본 연구는 수술간호팀 간호사의 환자존엄성에 대한 실천과 관련 요인을 파악하기 위한 서술적 조사연구이며 수술환자의 존엄성에 대한 간호사의 실천을 높이기 위한 기초 자료를 마련하고자 시도되었다. 본 연구는 경기도 소재 일 대학병원에 근무하는 수술간호팀 간호사 103명을 대상으로 2018년 2월 5일부터 2월 9일까지 자료를 수집하였다. 구조화된 질문지법을 이용하여 Ferri 등(2015)과 박연옥 등(2006)이 개발한 도구를 수정·보완한 도구로 수술간호팀 간호사의 환자존엄성 실천과 인식을 측정하였다. 환자존엄성 실천의 장애정도는 Macaden 등(2017)이 환자존엄성 실천에 방해가 되는 요인을 도출한 모형을 토대로 구성한 도구로 측정하였다. 본 연구의 결과를 요약하면 다음과 같다. 1. 대상자의 환자존엄성 실천은 평균평점 4.14점(5점 만점)이었다. 하위 영역에서 신체적 프라이버시 영역(4.08점)의 실천 정도가 가장 낮았고 정보 및 자율성 영역(4.17점)과 간호사-환자 상호작용 영역(4.17점)의 점수가 같았다. 대상자의 환자존엄성 인식은 평균평점 4.57점(5점 만점)이었다. 하위 영역에서는 정보 및 자율성 영역(4.60점), 신체적 프라이버시 영역(4.58점), 간호사-환자 상호작용 영역(4.54점)순으로 인식 정도가 높게 나타났다. 대상자의 환자존엄성 실천의 장애정도는 평균평점 3.29점(5점 만점)이었고 업무적 요인(3.66점), 조직적 요인(3.50점), 환경적 요인(3.36점), 개인적 요인(2.68점) 순으로 높았다. 대상자의 일반적 특성에 따른 실천의 차이는 통계적으로 유의하지 않았다. 2. 대상자의 환자존엄성 실천은 환자존엄성 인식, 환자존엄성 실천의 장애정도와 각각 통계적으로 유의한 상관관계를 나타내었다(r= .53, p〈 .001, r=.-46, p〈 .001). 환자존엄성 인식과 환자존엄성 실천의 장애정도 간의 상관관계는 통계적으로 유의하지 않았다(r= -.17, p= .084). 3. 대상자의 환자존엄성 실천의 영향요인은 환자존엄성 인식(β=.60, p〈.001)과 환자존엄성 실천의 장애정도(β=-.32, p〈.001)로 총 41.4% 설명력을 나타내어 유의한 예측 요인으로 나타났다(R2=.414, F=35.28, p〈.001). 이상에서 수술간호팀 간호사의 환자존엄성 실천의 영향요인은 환자존엄성 인식과 환자존엄성 실천의 장애정도임을 확인하였다. 따라서 환자존엄성 실천을 높이기 위해서는 간호사의 환자존엄성에 대한 인식을 높이고 환자존엄성 실천의 장애요인을 개선하기 위한 전략이 필요하다.

경력단절 기혼 여성의 취업교육 실태 및 발전방안 연구 : 수도권 여성인력개발센터를 중심으로

장희수 한국방송통신대학교 평생대학원 2009 국내석사

While the increased opportunities for the education of women as well as social progress increased the married women's demand for employment Still, women's career interruption still happens caused by task performance in the life cycle of married women. Long career interruption lowers married women's status in the labor market and makes worse imbalance between their demand for employment and employment conditions in the labor market, which seems to result from prejudices against them and from their lack of understanding of social changes. Therefore, systematic education ranging from basic training to cope with social change to vocational education arc essential for career-interrupted women who want to be employed. However, vocational education institutions for women cannot get a correct understanding of married women's demand for employment or that of the employment field going through various changes, thus failing to provide efficient vocational education. Since even national employment support projects for married women fail to fully consider their environment and characteristics and associations with employment, with significance given to quantitative increase rather than qualitative improvement, it is hard to expect long-term effectiveness from the projects. Such a phenomenon is more serious in Seoul and the Metropolitan area where disproportionate emphasis is laid on woman resources. Prior studies dealt with causes of failing to activate employment of married women, mainly in terms of their will and attitude for getting a lob, child-rearing, maternity protection system, or policies. Considering universalization of the phenomenon of hiagher education among women, however, it will be necessary to compare differences by other employment factors, such as age, career, and the interruption period. So this study set the following questions to conduct a research. First, how do employment motives among career-interrupted married women in the Metropolitan area differ by age, educational background, and the period of career interruption? Second, how do views of vocational education among career-interrupted married women in the Metropolitan area differ by age, educational background, and the period of career interruption? Third, how do views of employment projects among career-interrupted married women in the Metropolitan area differ by age, educational background, and the period of career interruption? A sample was made of 220 married women participating in vocational education at such vocational education institutions for women in the Metropolitan area as the Seoul Women's Skills Development Institute, the Dongdaemun Woman Resources Development Center, and the Northern Gyeonggi Province Women Vision Center to conduct a survey. 179 valid ones were analyzed by using SPSS PC win 12.0, with the exception of 32 which were completed by unmarried women or contained insincere responses, consequently drawing the following conclusions. First, composition and background properties of married women, who are trainees in vocational education institutions for women in the Metropolitan area, are as follows: As for the general composition of trainees in vocational education institutions for women in the Metropolitan area, more than 80% were in their thirties or forties; 79.4% were at a high education level as college graduates or higher; 80.4% had experience of being employed; and the majority of them had the interruption period of 3 to 5 years. This implies that higher-education married women in the middle class have their consciousness of employment spread positively and that it is necessary to make qualitative improvement in vocational education to meet their participation. Second, there were statistically significant differences by education background and age in terms of their employment motives, criteria for selecting a job, obstacles of employment, and desired job. The criteria for selecting a job differed by employment motives: women in their thirties mentioned economic reasons, which reflects realistic matters, such as child-rearing or child education, and many of those in their forties and fifties suggested preparation for their old age. Most of the women in their twenties wanted professional work, those in their thirties or forties wanted educational service work, and those in their fifties wanted general service work. The higher educational level and the younger, the higher average monthly income they wanted. As for views of necessary support for employment, the majority of them suggested "diversification of vocational education programs," regardless of age, educational background, or interruption period, contrary to expectation. This demonstrates that married women urgently need development of various new job models and vocational education programs suitable for their age group. Third, respondents' views of vocational education are as follows: Most of the married women needed education for employment; as for a proper period of vocational education, women in their fifties or over suggested three months or less while those in their twenties suggested one year or less, which implied that the older women were, the earlier employment they wanted. In other words, older married women have greater anxiety about employment due to the age limits. They were visiting such educational institutions for women as women development centers and woman resources development centers to get vocational education; as for motives of participation in education, many of them expected getting a certificate through short-term education or possibilities of association with employment. Most of the married women in their forties or over who lacked information skills were getting information about employment through people around them, and were primarily visiting educational institutions for women to get vocational education because of lower educational expenses or expectation of association with employment. This implies that differentiated types of vocational education are necessary by age or career interruption period. Fourth, respondents' views of nationally-supported employment projects are as follows; As for experience of participating in nationally-supported employment support projects, the majority of them had no such experience, mostly because of insufficient institutional PRs. They still have low awareness of nationally-supported projects because most of the beneficiaries are restrictively those in their thirties to 49, probably because of lack of active PRs by educational institutions. On the basis of the results, the following improvement direction can be suggested in terms of vocational education for career-interrupted married women. First, it is necessary to provide more specifically segmented and diverse vocational education programs for career-interrupted married women according to various requirements and personal skills by regional conditions and their background properties. Second, it is necessary to support service equipment of educational institutions for trainees. Educational institutions for women mainly have trainees in their thirties to forties. The biggest burden against vocational education for them is child-care and child-rearing. It is therefore necessary for them to supplement service facilities for their trainees. Third, it is necessary to develop effective, rational nationally-supported vocational education and projects in consideration of married women's circumstances. Fourth, it is necessary to reinforce expertise of educators in order to improve vocational education institutions for married women. In conclusion, as the aging phenomenon and low childbirth become serious social problems, it is first necessary to provide differentiated, rational support to meet local conditions by fully considering requirements and views of employment according to their background properties and age in order to settle career-interrupted married women's employment as a natural social phenomenon.

본 연구의 목적은 학교문화예술교육의 파트너십에 관하여 예술강사의 경험을 살펴보고, 예술강사의 입장에서 그 경험을 통해 인식한 파트너십의 필요성에 대한 정보를 제공하는 데 있다. 본 연구는 예술강사로서 학교문화예술교육의 경험을 통하여 연구문제를 탐색하였다. 연구의 목적을 달성하기 위해 예술강사로 지내온 시간과, 학교문화예술교육 현장에서의 파트너십에 관한 성찰이라는 연구 문제를 설정하여 자문화기술지의 방법으로 탐구하였으며 두 가지의 연구 결과를 도출하였다. 첫 번째 연구 결과는 연구자 본인이 예술강사로 지내온 시간에 대한 성찰을 하였다. 먼저 예술강사로 지내온 교육경험의 기간을 세 가지 시선을 기점으로 나누었으며, 그 시기에 예술강사로서 경험한 사례를 통하여 예술강사의 정체성 형성과정에 대한 성찰을 확인하였다. 두 번째 연구 결과는 학교문화예술교육 현장에서의 파트너십에 관한 성찰을 확인하였다. 예술강사의 시각에서 바라 본 학교문화예술교육의 파트너십의 유형에 따라 학교문화예술교육에서의 직·간접적 관여자를 분류하였으며, 학교문화예술교육에서의 파트너십의 필요성을 예술강사의 위치에서 경험한 사례와 관계자 유형에 따라 분류하여 성찰한 결과를 나타내었다. 본 연구는 학교문화예술교육에서의 파트너십의 필요성에 대하여 연구자 본인의 예술강사로 지내온 시간에 관하여 성찰하고, 더 나아가 학교문화예술교육의 현장에서의 파트너십에 관한 성찰을 하게 되었다. 본 연구에서 다룬 예술강사의 시각에서 살펴 본 학교문화예술교육의 파트너십에 대한 내용만으로는 예술강사 모든 예술강사의 입장을 일반화하기에는 어려움이 있을 것이다. 하지만 본 연구를 통하여 학교문화예술교육에서 발생할 수 있는 다양한 상황이나 어려운 문제에 있어서 또 다른 시각으로 살펴보는 것에 도움을 줄 것이라 기대한다.

아동권리 교육 프로그램에 대한 교사와 부모의 인식 조사

장희수 세종대학교 교육대학원 2009 국내석사

아동은 태어나면서부터 자신의 권리를 향유할 가치 있는 권리의 주체로 존재하며 아동의 권리증진을 위해서는 교사와 부모들이 아동권리에 대한 필요성을 인식하는 것이 중요하다. 자신의 기본 권리를 존중받지 못한 아동들의 경험은 자신의 권리와 타인의 권리를 존중하고 옹호하는 성인으로 자라나기 힘들기 때문이다. 연구자는 세이브더칠드런에서 제공한 프로그램을 기초로 수정 보완된 생존권, 보호권, 발달권, 참여권에 대한 아동권리프로그램들을 현장에서 5년 동안 유아들에게 직접 적용하여 아동권리 교육 프로그램을 개발하였으며, 현장에서 유아들과 생활하는 교사와 유아들의 부모들에게 아동권리교육 프로그램을 제시하였다. 이에 본 연구는 교사와 부모를 대상으로 아동권리 교육 프로그램에 대한 필요성과 지식수준을 조사하여 아동권리프로그램의 효과적인 운영을 위한 기초자료를 제공하고자 하였다. 본 연구의 목적을 달성하기 위한 연구문제는 다음과 같다. 1. 교사와 학부모의 인구사회학적 변인에 따른 아동권리 교육 프로그램의 지식 수준과 필요성 인식비교 2. 아동권리 교육 프로그램에 대한 지식수준 3. 아동권리 교육 프로그램에 대한 필요성 인식 4. 아동권리 교육 프로그램에 대한 지식수준과 필요성에 영향을 미치는 변인들 의 영향력 위 문제를 알아보기 위하여 서울시에 위치한 국·공립 어린이집 20곳을 선정하여 그곳에 재직 중인 교사와 재원 중인 영유아의 학부모에게 각각 170부를 배포였으며 교사 159부, 학부모 153부가 최종 분석 자료로 사용되었다. 수집된 자료의 분석을 위해 평균과 표준편차를 산출하였으며 t-test, One-way ANOVA, Scheffe 사후검증, 단계적 중다회귀 분석을 실시하였다. 본 연구에서 제시한 연구문제에 따른 결론을 요약하면 다음과 같다. 1. 교사와 학부모의 인구사회학적 변인에 따른 아동권리 교육 프로그램의 지식수준과 필요성을 다음과 같이 해석하였다. 첫째, 교사의 연령, 경력, 담당연령에 따라 아동권리 교육 프로그램의 지식수준과 필요성의 차이는 없는 것으로 나타났다. 둘째, 학부모를 조사한 결과 연령, 학력, 소득수준, 자녀수에 따른 지식수준에는 차이가 없었으나 필요성 인식에 있어서는 자녀의 수가 1명인 경우에는 2명 이상일 경우와 비교하여 더 높게 인식하는 것으로 나타났다. 2. 교사와 학부모의 아동권리 교육 프로그램에 대한 지식수준을 알아본 결과는 다음과 같다. 첫째, 교사와 학부모의 지식수준에서는 기본개념, 생존권, 보호권, 발달권, 참여권의 모든 영역에서 교사가 학부모보다 유의하게 높게 나타났다. 이는 교사가 학부모보다 아동권리 교육 프로그램에 대한 정보에 접근이 용이하며, 아동권리에 대해 더 잘 알고 있는 것으로서 유아교육과 보육의 전문가로서 매우 의미 있는 결과라고 해석된다. 둘째, 아동권리협약의 기본개념에 대한 프로그램 지식수준에서는 교사와 학부모 모두 아동권리와 역사에 대한 지식수준이 가장 낮게 나타났다. 이는 아동권리의 기본개념에 대한 정확한 지식과 홍보가 미흡해 프로그램을 접해보지 못한 현실적인 어려움으로 해석될 수 있다. 3. 교사와 학부모의 아동권리 교육 프로그램에 대한 필요성에 대한 인식수준을 알아본 결과는 다음과 같다. 첫째, 교사와 학부모의 아동권리 교육 프로그램의 필요성 인식을 비교해본 결과 교사가 학부모보다 아동권리 교육 프로그램의 필요성을 더 높게 인식하는 것으로 나타났다. 연구 결과 보호권에 대한 프로그램 필요성이 가장 높게 나타났으며, 기본개념에 대한 필요성이 가장 낮게 나타났다. 둘째, 아동권리협약 기본개념에 대한 프로그램 필요성의 인식을 알아본 결과 교사와 학부모가 유의미한 차이를 보인 문항은 ‘비차별’과 관련된 문항이며, 학부모가 교사보다 높게 나온 문항은 ‘체벌’과 관련된 문항이다. 4. 교사와 학부모의 아동권리 교육 프로그램에 대한 지식수준과 필요성에 영향을 미치는 관련변인들의 영향력을 알아보았다. 첫째, 교사의 인구사회학적 변인들 중 연령, 학력, 경력, 담당아동연령이 아동권리 교육 프로그램 지식수준에 미치는 영향을 알아보기 위한 단계적 중다회귀분석 결과가 유의한 설명력을 가지지 못하는 것으로 나타났다. 이러한 결과는 교사의 아동권리 교육 프로그램에 대한 지식과 프로그램의 필요성에 대한 인식이 적기 때문이다. 둘째, 학부모 가정의 인구사회학적 변인들 중 연령, 성별, 학력, 소득, 자녀수가 학부모의 아동권리 프로그램 지식수준에 미치는 영향력을 알아본 단계적 중다회귀분석 결과에서도 위 변인들이 유의한 설명력을 가지지 않는 것으로 나타났다. 이러한 결과는 앞서 설명한 교사의 경우와 마찬가지로 학부모에게 아동권리와 관련된 정보를 제공하는 교육이 실시된다면 프로그램의 필요성과 인식도 높아질 것임을 보여준 의미 있는 결과라고 할 수 있겠다. 본 연구를 통해 얻을 수 있는 제언은 다음과 같다. 첫째, 아동권리협약에 대한 프로그램을 모든 유아교육기관이 적용할 수 있고 이해하기 쉽게 연구 개발이 필요하다. 둘째, 아동들의 참여를 독려하는 참여권 교육이 From the moment he is born, a child is the subject of rights who can enjoy his rights. That is to say, a child is not an adult's property, nor an incapable being that should always be protected only because he is young. A child who had experienced his basic rights being ignored is less likely to become an adult who respects his and other people's rights. To enhance children's rights, it is important for teachers and parents to know the necessity of children' rights. Thus, in this study, I have presented and developed programs about right to live, right to be protected, right to be developed and right to participate by monitoring and modifying a program for children's rights based on the program provided by Save the Children, and an educational program for enhancing children's rights that has been used in my day care center for five years. I wanted to know the necessity and the knowledge level toward children's rights by presenting educational program for children's rights to teachers and parents and by studying their awareness of the issue. Research topics are as below. 1. Compare the necessity and knowledge level toward children's rights educational program based on the change of sociology of population of teachers and parents 2. Knowledge level toward children's rights educational program 3. Necessity toward children's rights educational program 4. The effectiveness of changes that affect necessity and knowledge level toward children's rights educational program In order to study the above topics, 20 day care centers in 00-gu in Seoul both state-run and public were chosen, 170 copies were sent to teachers working there and parents whose kids were using the centers each, and 159 copies from the teachers and 153 copies from the parents were used for the final analysis. To know the necessity and knowledge level toward children's rights educational program through statistical analysis of the collected materials, average and standard deviation were calculated. To verify the difference as the necessity and knowledge level changes when the object of study changed, t-test and One-way ANOVA, scheffe post verification have been conduted, and to figure out the effectiveness of the changes, multiple regression analysis was used. Conclusions to the research topics in summary are as below. 1. I have interpreted the necessity and knowledge level toward children's rights educational program based on the change of sociology of population of teachers and parents as such. First of all, there were no differences of the necessity or level of knowledge toward children's rights educational program based on a teacher's age, educational background, career experience or the age of the child the teacher is taking care of. Second, for the parents, the knowledge level showed no difference. However, parents with the only child were more likely to think that the program is necessary than those with two children or more. 2. The level of knowledge toward children's rights educational program of teachers and parents was as below. First of all, through the entire part, teachers knew remarkably better than parents about children's rights educational program. This is a meaningful result for an expert in child education and nurture. Second, among the questions about knowledge level of basic concepts of the convention on the rights of the children, both teachers and parents showed the lowest level about children's rights and history. This shows that until now, not many have encountered programs about basic concepts of the rights of children. 3. The awareness of the necessity toward children's rights educational program of teachers and parents was as below. First, by comparing the necessity level of teachers and parents, more teachers have been proven to think that children's rights educational programs are necessary that parents. Among them, the necessity level toward a program related to the right to be protected was the highest, while the lowest was a program about basic concepts. Second, the results of necessity toward a program related to basic concepts of the convention on the rights of the children, those answers showed a remarkable difference between teacher and parents were questions about nondiscrimination, and the questions in which parents felt more necessary than teachers were about 'punishment'. I think 'sharing the feeling of being punished' has been difficult for teachers. 4. I studied on the effectiveness of changes that affect necessity and knowledge level toward children's rights educational program. First of all, it turned out that the results of multiple regression analysis to see the effectiveness of teachers' changes in sociology of population such as age, educational background, career experience, and the age of the child the teacher is taking care of, have not provided a good explanation. This is because the knowledge and necessity toward children's rights educational program of teachers were low. Second, it turned out that the results of multiple regression analysis to see the effectiveness of parents' changes in sociology of population such as age, sex, educational background, family income, and the number of their children, have not provided a good explanation either. This is a meaningful result that suggests a meaningful lesson that when there are programs that provide information about children's rights to parents, their necessity and knowledge level will go up. The proposals this study is offering are as below. First of all, programs about the convention on the rights of the children should be developed in a way that everyone can easily understand and adopt. Second, education programs that encourage more participation of children should be applied more often. Third, as the research shows that the more you know about children's rights educational program, the better you feel the necessity. Thus, it is important to let people know more about children's rights and hav

In biological systems, numerous biological components work with complexed pathway, but a series of procedures of reaction cascade are regulated in a sophisticated manner. As the key components involved in sophisticated regulation are discovered, many researchers have published their studies about engineering application of the biological system. In this work, among the various biological reactions, we focused on identification strategy of selective coupling reactions between biological components for biosensor applications. In order for identification of reaction signal, we used polydiacetylene (PDA) nanomaterial and gold nanoparticle (AuNP) which has unique optical properties. This thesis divided to four chapters. In first chapter, we described research background and, especially introduced physical and optical properties of nanomaterials to aid understanding of this study. In second chapter, we described several identification results for engineering application that based on PDA nanomaterial. We developed hydrogel encapsulated PDA based genetically modified (GM) crop detection sensor and fish-gill like microfluidic channel embedded PDA sensor for bacteria detection, and PDA functionalized paper-based toxin, bacterial spore, detection kit. In third chapter, we introduced AuNP based identification result and engineering applications. We developed AuNP coated plastic chip based portable GM crop detection system that utilize localized surface plasmon resonance (LSPR) phenomenon of AuNP, and we introduced simplified bioreceptor evaluation kit based on AuNP embedded lateral flow immunoassay (LFIA) strip. In forth chapter, we summarized this work and overlooked future research. Through this study, we could be able to identify invisible biological coupling interactions for engineering applications. We expected that the detection and evaluation platform that developed in this study for specific purpose could be able to apply in practical application such as the point-of-care testing (POCT) platform.

Today, crime victims are no longer bystanders in criminal proceedings. They can participate in criminal proceedings to protect their rights and losses. The Constitution and criminal procedure law adopted new provisions regarding crime victims rights. New legislations also followed to achieve the objectives of the new provisions. There are several provisions in constitutional law such as article 10(provision of human dignity, worth and the right to pursue happiness), article 17(provision of inviolable right to privacy of life), article 21 (4) (provision that speech or the press shall not violate the honor or rights of other persons), article 27 (5) (provision that a victim of a crime shall be entitled to make a statement during the proceedings of the trial of the case involved as under the conditions prescribed by Act), article 30(provision that any citizen who has suffered physical injury or death due to criminal acts of others may receive aid from the State under the conditions as prescribed by Act) which are constitutional bases of victim support. These are very significant in point of presenting the legislation direction against a victim support law and becoming standards which are used for interpretation for relation law and execution of victim support policy. The protection for a crime's victim is specified in the Act to Protect Crime's Victim. Act to Help Crime's Victim, Act on Punishment of Sexual Violent Crime and Protection for Victim, etc., Act on Criminal Procedure. Act on Public Prosecutor's Office. Rule on Criminal Procedure. Rule on Duties of Judicial Police Officer. Act on Road Traffic, Criminal Act, Special Act on Punishment of Special Crime of Violence, Act on Children's Welfare, Special Act on Punishment of Crime of Family Violence, Act on Prevention of Family Violence and Protection of Victim, and Special Act on Lawsuit Facilitation, etc. Although the protection for victims is thought to be thoroughly guaranteed with such laws, the subject is mainly limited to a particular crime relating to female victims from a sexual violence, family violence, and prostitution, etc. And there is a limitation due to an insufficient finance and specialized manpower, etc. regarding the protection and support for victims of such crimes. which is the current reality. This article describes the reactions to the crime-victim protections by the police as mechanisms of Criminal Justice System for the purpose of protecting the victims. Even though the basic duty of the police is to protect the people from the crimes the police has usually emphasized not on the crime-victims but only on the assaulters. Although crime victims were given an unfair encroachment, they endure prejudice and blame of social. Owing to these situation, most of criminal victims don't reveal the truth honorably and be distressed. It is tried to find the countermeasure toward crime-victim protections in the police on the basis of the practical operation in the advanced countries.

Predictive Models for Blockchain, Cryptocurrency, and Derivatives Market

장희수 서울대학교 대학원 2018 국내박사

This dissertation aims to conduct the empirical analysis for the financial derivative and cryptocurrency market and to develop analytical techniques based on machine learning models suitable for prediction and estimation of each field. In the financial derivative market, a Markov chain Monte Carlo (MCMC) methods employ the candidate probability distribution nearest to the target probability distribution to acquire sample distributed from the posterior density. Choice of the candidate probability distribution affects the practical convergence speed of the MCMC methodology and the fitness of the sample. In this dissertation, we propose a MCMC framework possible to samples from the candidate distribution nearest to the target probability density without the specification of the candidate distribution. We confirm that the jump diffusion models and Bayesian neural networks have the best performance in estimating and predicting given the data of the recent day for the model estimation given S&P index options in 2012. Especially, the jump diffusion model has a very high performance in terms of domain adaptation between the American option and the European option. This difference is reflected in the fact that the jump diffusion model is based on the common asset of the American option and the European option. Based on this empirical precedent study, we proposed a machine learning model called generative Bayesian neural network (GBNN) to overcome the disadvantages of the machine learning model. GBNN maximizes posterior probability through the GBNN obtains prior information from the GBNN data learned up to the previous day, and learns likelihood probability from actual trading data of learning day. We identify that the GBNN model outperform other benchmark models in terms of model prediction. Bitcoin is a successful cryptocurrency, and it has been extensively studied in fields of economics and computer science. In this dissertation, we analyze the time series of Bitcoin price with a BNN using Blockchain information in addition to macroeconomic variables. We conduct the empirical study that compares the Bayesian neural network with other linear and non-linear benchmark models on modeling and predicting the Bitcoin process. Our empirical studies show that BNN performs well in predicting Bitcoin price time series and explaining the high volatility of the Bitcoin price in Aug. 2017. In addition, we suggested the enhanced GRU model for correlation analysis between cryptocurrency markets. Assuming that the gate value obtained from the GRU model is the parameter of the VAR model, it makes possible to visualize the correlation between various alternative currencies in the cryptocurrency market. As a result, it is confirmed that there is a very significant correlation between the currencies separated from the existing currencies and the existing currencies.

Despite the rising importance of visual landscapes as well as the importance of landscape elements according to the types of landscapes, there is a shortcoming in interest and research regarding the citizens who directly benefit from this landscape. Although the subject has been addressed in many studies, there is a divergence in the perspectives of specialists and users, and there were relatively view studies which took the characteristics of users under consideration. Among these individual characteristics, there have been a dearth of research regarding different age groups which will reflect social experiences and the trends of the era have been shortcoming. The present study identified open spaces and public facilities among the types of landscapes and accordingly categorized types and specific factors. These factors were employed to conduct a comparison of variances in perception according to age. For this purpose, the following factors were established based on the results extracted from theoretical examinations and a study of the region selected as the subject of research. The designated research subject region was the site including the intercity bus terminal and the express bus terminal in the Gagyeong- dong, Heungdeok-gu in Cheongju city of the Chungcheongbuk-do province. The types of landscapes were determined to consist of open spaces and public facilities. The landscape elements of the open spaces and the detailed components to be researched were accordingly established as the following. ?E Pleasantness ?V Open public sites, green spaces, rest areas ?E Accessibility ?V vehicle roads, pedestrian roads, plazas The landscape elements of the public facilities and their detailed components were established to be the following. ?E Public amenities - benches, pergolas, bicycle storage racks, public phone booths, guide signs ?E Functionality ?V waste baskets, street lamps, production lighting, and booths for management of facilities ?E Eco-friendliness ?V roadside planters, street lining trees, flower beds ?E Safety ?V traffic lights, protective fences, bollards, bus stops (bus shelters) The component elements were designates as above. Also, prior to the survey an on-site investigation was conducted, which was followed by the survey of 167 persons using the site of research. The results of the survey thus implemented were analyzed using the PASW Statistics 18 program of SPSS Inc. for statistical processing. The results demonstrated that across all age groups, the open space landscapes were perceived to be the more important type of landscape than public facilities. Broke down by age group, respondents in their teens perceived accessibility as an important component, and among the specific elements, pedestrian roads were regarded as important. Among respondents in their twenties, pleasantness and accessibility in open spaces were prioritized with equal ratios and green spaces and pedestrian roads were respectively perceived to be important specific components of pleasantness and accessibility. Respondents in their thirties perceived accessibility to be the important component, and pedestrian roads to be the important specific element. Meanwhile, unlike respondents in the younger age groups who had prioritized accessibility, those in their forties perceived pleasantness to be of greater importance, and regarded green spaces and rest areas to be equally important specific components. Lastly, respondents in their fifties or older were found to identify pleasantness within the landscape type of open spaces to have greater relative importance as in the cases of those in their forties, and they considered green spaces to be the important specific component. As different age groups thus had varying perceptions, henceforth when dealing with landscapes it will be necessary to pay more prudent aware of social responses, in particular to take close attention to potential variances in responses accordingtothevarietyofagegroups. This study illuminates the importance of the impact exercised by the variances in age groups on landscape perception, and may be utilized as important foundational data for planning and designing landscapes.

All over the world, COVID19 has reached such a serious stage that the World Health Organization (WHO) has declared a pandemic. As a result, indoor activities have increased in countries around the world, such as regulating contact between people and refraining from outside activities. This phenomenon is leading to the growth of services that can enjoy leisure time at home, and online learning platforms that can receive education remotely are drawing attention. This trend has led to the online transition of craft education, which has long been available offline. The online craft education is generally a hobby education, and provides a curriculum to purchase materials and online tickets from the online craft learning platform to create high-quality works with a small effort. However, we could see that the satisfaction level of online craft learning dropped significantly compared to offline, even though small efforts could create high-performing works. Accordingly, the purpose of this study was to develop an online craft learning platform usability evaluation item considering the online and offline craft learning experience to improve the problem of using crafts that were offline as they switched online. The concept of online craft learning platform, ease of use, and UI design was reviewed and case studies were conducted based on this. In the case study phase, the contents, UI design, and GUI design of online craft learning platform were investigated for the top four platforms with market share. Afterwards, a survey was conducted on online and offline craft learning experiences to investigate learning status, learning satisfaction and learning obstruction factors, learning convenience and experience, convenience and UI satisfaction at the learning stage, and improvement items. Based on the contents of the case study and survey, we drafted an online craft learning platform usability evaluation tool and used Delphi techniques to go through three modifications and reviews to a group of experts. The Delphi survey resulted in an assessment of the ease of use of online craft learning platforms. Task performance times for each platform were then measured and observed by designing tasks according to the craft learning steps. In addition, we conducted an in-depth survey to classify the items of convenience of using online craft learning platforms as three factors, and validate their reliability through reliability analysis. Later, based on items with secured reliability, the convenience of use and overall satisfaction between online craft learning platforms were compared and analyzed. As a result of this study, the online craft learning platforms "Class 101" and "ideas" were compared and analyzed based on 11 tasks according to the learning stage and 10 of the usability evaluation items. For the overall task, class 101 has the shortest performance time, indicating high usability. Characteristically, the task, which showed a large gap between platforms, was shown as lecture page movement, question entry, and lecture movement task. The 21 questions of online craft learning platform evaluation items derived through the Delphi survey were derived from 10 questions after deleting items that were not secured with reliability through factor analysis and reliability analysis. As a result of factor analysis, the evaluation items could be classified as three factors: "Accessibility to Learning Information," "Communication between Professors and Students," and "Academic Information Recognition." Analysis of each platform in 13 sub-items according to three factors resulted in the highest overall satisfaction of Class 101 and the lowest satisfaction of the Harvey Pool. In the future, online craft learning platforms will need to improve the course of exploration, such as search engines and the visibility of categories, so that they can easily reach learning information. It will also be necessary to improve communication between professors and students so that questions generated during the course can be easily solved and quickly entered and received feedback during the course. It is expected to increase the loyalty of online craft learners if they improve the online craft learning experience to recognize it as an emotional experience through overall content diversification as well as in terms of ease of use. This study is intended to improve the ease of use and learning satisfaction of online craft learning platforms, and could serve as a foundation to complement the problems of existing online craft learning platforms. 전 세계적으로 코로나19(Covid19)이 대유행함에 따라 세계보건기구(WHO)가 팬데믹을 선포할 정도로 심각한 단계에 이르렀다. 이에 따라 세계 각국에서는 사람 간의 접촉을 규제하고, 시민들은 외부 활동을 자제하는 등 실내 활동이 증가했다. 이러한 현상은 집에서 여가생활을 즐길 수 있는 서비스들의 성장으로 이어지고 있고, 원격으로 교육을 받을 수 있는 온라인 학습 플랫폼들이 주목받고 있다. 이러한 흐름은 오랫동안 오프라인 방식으로 제공되던 공예 교육을 온라인으로 전환하도록 이끌고 있다. 온라인상에서 진행되는 공예 교육은 전반적으로 취미교육에 해당하는 내용으로, 온라인 공예 학습 플랫폼에서 손질된 재료와 온라인 수강권을 구매해 작은 노력으로 완성도 높은 작품을 만들어 볼 수 있는 커리큘럼을 제공하고 있다. 그러나 작은 노력으로 성취도 높은 작품을 만들 수 있음에도 불구하고 온라인 공예 학습의 만족도가 오프라인에 비해 크게 떨어지는 것을 볼 수 있었다. 이에 따라 본 연구에서는 오프라인으로 이뤄지던 공예 교육이 온라인을 전환함에 따라 사용편의성이 떨어지는 문제를 개선하고자 온·오프라인 공예 학습 경험을 고려한 온라인 공예 학습 플랫폼 사용편의성 평가항목을 개발하는 것을 목적으로 진행되었다. 온라인 공예 학습 플랫폼, 사용편의성, UI 디자인의 개념에 대해 알아보고 이를 바탕으로 사례 조사를 실시했다. 사례 조사 단계에서는 시장 점유율 상위 4개 플랫폼을 대상으로 온라인 공예 학습 플랫폼의 콘텐츠, UI 디자인, GUI 디자인에 대해 조사했다. 이후 온·오프라인 공예 학습 경험자를 대상으로 설문조사를 실시하여 학습 현황, 학습 만족도 및 학습 방해요소, 학습 편의성 및 경험, 학습 단계별 편의성 및 UI 만족도, 개선 항목에 관해 조사했다. 사례조사와 설문조사의 내용을 바탕으로 온라인 공예 학습 플랫폼 사용편의성 평가도구 초안을 제작하였고, 이를 델파이 기법을 활용하여 전문가 집단에게 3차례에 걸친 수정 및 검토 과정을 거쳤다. 델파이 조사를 통해 온라인 공예 학습 플랫폼 사용편의성 평가항목을 도출했다. 이후 공예 학습 단계에 따른 Task를 설계하여 각 플랫폼 별 Task 수행 시간을 측정 및 관찰했다. 또한 심층 설문조사를 실시하여 온라인 공예 학습 플랫폼 사용편의성 평가항목을 3개의 요인으로 분류했으며, 신뢰도분석을 통해 신뢰도를 검증했다. 이후 신뢰도가 확보된 항목을 토대로 온라인 공예 학습 플랫폼 간 사용편의성과 전반적인 만족도를 비교 분석했다. 본 연구는 결과적으로 온라인 공예 학습 플랫폼 ‘클래스101’, ‘아이디어스’를 학습 단계에 따른 Task 11개와 사용편의성 평가항목 중 10개 항목을 토대로 비교 분석했다. 전반적인 Task에 있어서 클래스101의 수행 시간이 가장 짧아 사용편의성이 높은 것으로 나타났다. 특징적으로 플랫폼 간의 격차가 크게 나타난 Task는 강의 페이지 이동, 질문 입력, 강의 이동 Task로 나타났다. 델파이 조사를 통해 도출한 온라인 공예 학습 플랫폼 평가항목 21문항은 요인분석과 신뢰도분석을 통해 신뢰도가 확보되지 않은 항목을 삭제 과정을 거쳐 10문항을 도출해 이를 바탕으로 플랫폼 별 비교 분석을 진행했다. 요인 분석 결과 평가항목은 ‘학습 정보 접근성’, ‘교수자와 수강생의 소통’, ‘학습 정보 인식성’ 3개의 요인으로 분류할 수 있었다. 3개의 요인에 따라 13개의 하위 항목으로 각 플랫폼을 분석한 결과 전반적으로 클래스101의 만족도가 가장 높게 나타났고, 하비풀의 만족도가 가장 낮게 나타났다. 향후 온라인 공예 학습 플랫폼은 사용자가 원하는 공예 학습 콘텐츠를 검색할 수 있도록 검색엔진을 강화하는 등 강의 탐색 과정 개선해야할 것이다. 또한 수강 과정에서 발생한 질문을 쉽게 해결할 수 있도록, 질문 입력 UI를 제공하여 교수자와 수강생 간의 소통을 개선해야할 것이다. 향후 사용편의성 측면뿐 아니라 전반적인 콘텐츠 다양화를 통해 온라인 공예 학습 경험을 감성적인 경험으로 인식할 수 있도록 개선한다면, 온라인 공예 학습자들의 충성도를 높일 수 있을 것으로 예상한다. 본 연구는 온라인 공예 학습 플랫폼의 사용편의성과 학습 만족도 향상을 위한 것으로 기존 온라인 공예 학습 플랫폼의 문제점을 보완하는 기초자료가 될 수 있을 것이다.
