Changes in the external environment surrounding a company require a change in the way the company works, which eventually leads to a change in the way performance management is performed. Prior to the change in the performance management system, it is inevitable to evaluate the existing performance management system. In other words, it is necessary to analyze and study how the performance management system contributed to the achievement of management goals, which is the purpose of performance management. This study began with the need to analyze how each factor constituting the performance management system affects the acceptance of performance indicators and how the acceptance of performance indicators affects organizational performance. Previously, a number of studies have been conducted on how the performance management system affects the organizational behavioral perspective such as immersion, motivation, and leadership felt by members of an organization or company. However, research to investigate the relationship between the performance management system and the organization's performance is insufficient, and most of the research was conducted on public organizations such as public institutions and government ministries. Therefore, this study differentiated it from existing studies by analyzing how the performance management system of a company affects organizational performance by mediating the acceptance of performance indicators. In order to achieve the above research objectives, this study derived the research model and research hypothesis of this study by analyzing the results of previous studies related to the company's performance management system, performance index, acceptance of performance indicators, and organizational performance. After that, in order to analyze the relationship between each variable, a survey was conducted on corporate employees across the country, and finally, 210 copies of the survey results were analyzed. The verification results of the research hypothesis through analysis are as follows. First, it was found that the characteristics of the performance management system had a positive (+) significant effect on the achievement of performance indicators. Second, it was found that achievement of performance indicators had a positive (+) significant effect on corporate performance, and it was found that achievement of performance indicators mediated the relationship between the characteristics of performance management system and corporate performance. Third, it was confirmed that the characteristics of the performance management system had a positive (+) significant effect on corporate performance. Finally, it was confirmed that the characteristics of the performance management system, the achievement of performance indicators, and the indirect effect of corporate performance were significant, and that achievement of performance indicators had a mediating effect between the characteristics of the performance management system and corporate performance. First, it was found that the organizational culture centered on performance management, members' participation in performance management, and performance management operation had a significant positive (+) effect on organizational performance. Second, it was found that acceptance of performance indicators had a significant positive (+) effect on the organization's customer performance, financial performance, and human resource performance. Third, it was confirmed that the performance management system →acceptance of performance indicators → indirect effect between organizational performance was significant, and it was confirmed that the acceptance of performance indicators had a mediating effect between the performance management system and organizational performance. The implications for corporate performance management through the results of this study are as follows. Since the organization's performance-oriented organizational culture, participation of members in performance management, and operation of performance management have a positive effect on organizational performance, establishing and operating an efficient performance management system at the personnel management level can contribute to improving organizational performance. Therefore, corporate leaders and personnel managers should endeavor to promote participation of members in corporate performance management, form an organizational culture centered on performance management, and establish a systematic performance management operation system. In addition, the overall process for managing performance indicators such as evaluation through performance indicators should devise measures to increase the acceptance of members 기업을 둘러싼 대외환경의 변화는 기업이 일하는 방식의 변화를 요구하고 있으며, 이는 결국 성과관리의 방식의 변화를 초래한다. 성과관리 체계의 변화에 앞서, 기존 성과관리 체계를 평가하는 일은 불가피하다. 즉, 성과관리 체계가 성과관리의 목적인 경영목표 달성에 어떻게 기여를 했으며 어떤 효과 있는지 분석 및 연구하는 것이 필요한 것이다. 본 연구는 성과관리 체계를 구성하는 각 요소가 성과지표 수용도에 어떤 영향을 미치는지, 또한 성과지표의 수용도는 조직 성과에 어떤 영향을 미치는지에 대한 분석의 필요성으로부터 시작되었다. 기존에는 성과관리 체계가 조직이나 기업의 구성원이 느끼는 몰입감이나 동기부여, 리더십 등의 조직행동론적 관점에서 어떤 영향을 미치는지에 대한 연구가 다수 이루어졌다. 그러나 성과관리 체계와 조직의 성과와의 관계를 규명하기 위한 연구는 미비한 상황이며, 대부분의 연구가 공공기관 및 정부부처 등 공공조직을 대상으로 이루어졌다. 따라서 본 연구는 성과지표의 수용도를 매개하여, 기업의 성과관리 체계가 조직 성과에 어떤 영향을 주는지에 대해 분석하여 기존 연구와 차별화를 두었다. 본 연구는 위와 같은 연구 목적을 달성하기 위해 기업의 성과관리 체계, 성과지표, 성과지표 수용도, 조직 성과 등과 관련한 선행 연구 결과를 분석하여 본 연구의 연구 모형과 연구 가설을 도출하였다. 이후 각 변수 간의 관계를 분석하기 위해 전국의 기업 재직자를 대상으로 설문조사를 진행하여, 최종적으로 210부의 설문 결과를 분석하였다. 분석을 통한 연구가설의 검증 결과는 아래와 같다. 첫째, 성과관리 체계 특성은 성과지표 달성에 정(+)의 유의한 영향을 미치는 것으로 나타났다. 둘째, 성과지표 달성은 기업성과에 정(+)의 유의한 영향을 주는 것으로 화인되어 성과지표 달성이 성과관리 체계 특성과 기업성과 간의 관계를 매개하는 것으로 나타났다. 셋째, 성과관리 체계 특성은 기업성과에 정(+)의 유의한 영향을 주는 것으로 확인되었다. 마지막으로, 성과관리 체계 특성과 성과지표의 달성, 기업성과의 간접효과가 유의한 것으로 나타나 성과지표 달성은 성과관리 체계 특성과 기업성과 사이에서 매개효과가 있음이 확인되었다. 첫째, 성과관리 중심의 조직문화, 성과관리에 있어서의 구성원 참여, 성과관리 운영은 조직성과에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 성과지표 수용도는 조직의 고객성과, 재무적 성과, 인적자원 성과에 모두 유의한 정(+)의 영향을 미치는 것으로 ㅎ나타났다. 셋째, 성과관리 체계→성과지표 수용도→조직성과 간의 간접 효과가 유의한 것으로 확인되어 성과지표 수용도가 성과관리 체계와 조직성과 사이에서 매개효과가 있음이 확인되었다. 본 연구 결과를 통해 기업의 성과관리에 시사하는 점은 다음과 같다. 조직의 성과 중심 조직문화, 성과관리에 있어서의 구성원 참여, 성과관리 운영은 모두 조직성과에 긍정적인 영향을 미치고 있으므로, 인사관리적 차원의 효율적인 성과관리 체계를 구축·운영하는 것은 조직 성과를 향상시키는데 기여할 수 있다. 따라서 기업의 리더와 인사 담당자는 기업의 성과관리에 있어서 구성원의 참여 촉진, 성과관리 중심 적인 조직문화 형성, 체계적인 성과관리 운영 체계 구축을 위해 노력해야 한다. 또한 성과지표를 통한 평가 등의 성과지표 관리를 위한 전반적인 과정은 구성원의 수용성을 높일 수 있는 방안을 강구해야 할 것이다.

유다혜 대구대학교 대학원 2012 국내석사

This study aims to analyze geographical pattern of migration and to classify them by looking into migration of Daegu in 2001 and 2009 in unit of eup, myeon and dong. The results of this study disclosed under such objective and summarized as follows. First, not only population of Daegu but the number of total migrating population show constant stagnation and decrease. The number of total internal migration in Daegu also decreases due to constant outmigration to outer si and do regions and decrease of population by that. Second, the pattern of short distance movement appears to be predominant regarding the migration. The short movement within an administrative territory of autonomous district at near geographical distance seems to be more active. Third, the migration gets influenced much by houses stock. Some large residential areas in outer-city have been planned and development directly by local authority. Housing complexes attracted the various infrastructure and due to locational inertia and it shows tendency that population moves to outer-cities therefore. Fourth, It appears to be different for each age and region and the migration at the ages of 20∼30 appears to be more active. And, it is recognized that there is relation between the ages at teenagers which is school-age and their parents’ age. Lastly, the migration regions of Daegu is analyzed through factor analysis and cluster analysis. 27 and 29 small migration regions appeared in 2001 and 2009 and they are classified into 4 large migration regions again. The migration regions appear without getting out of premeditated living sphere of Daegu. 인구이동의 흐름은 기원지, 목적지라는 공간 요소와 이동자의 수를 구성하는 양적 요소를 가지기 때문에, 어느 지역의 사람들이 얼마나 어떤 지역으로 이동하는지를 밝히는 인구이동의 공간 패턴에 대한 분석은 도시 연구에서 중요한 의미를 갖는다. 그러나 기존에 행해진 인구이동에 대한 연구는 수도권에 집중되어 그 범위가 편향적이고 다양하지 않다는 한계점을 가진다. 특히 대구시의 인구이동의 기초 연구는 상대적으로 미흡한 편이다. 따라서 본 연구에서는 대구시를 사례로 2001년과 2009년의 인구이동을 읍・면・동 단위로 살펴보아 인구이동의 지리적 패턴을 분석하고, 대구시 내부 인구이동의 이동권을 구분 짓는 것을 목적으로 한다. 이러한 목적 아래 밝혀진 본 연구의 결과는 다음과 같이 요약된다. 첫째, 대구시의 인구수뿐만 아니라 총 이동인구의 수 또한 지속적인 정체 및 감소를 보이고 있다. 지속적인 외부 시・도 지역으로의 인구 유출과 이로 인한 인구수의 감소로 인해 대구시 내부의 총인구이동 수 또한 감소하였다. 둘째, 인구이동에 있어서 근거리 이동의 패턴이 우세하게 나타난다. 대구시 내부 이동에 있어서 지리적 거리가 가까운 자치구의 행정경계 내의 이동이 가장 활발하게 나타나며, 구 경계를 넘는 이동에 있어서도 행정구역의 경계지역에서 많은 이동이 발생한다. 셋째, 인구이동은 주택의 영향을 많이 받는다. 직할시 승격이후 편입된 월배, 성서, 공산, 안심, 고산, 칠곡과 같은 도시 외곽지역을 중심으로 대규모 주택단지로 개발이 이루어지며 공간구조가 형성되었다. 주택단지는 입지적 관성으로 각종 기반시설을 유입시켰고, 이에 따라 도시 외곽지역으로 인구가 이동하는 경향을 보인다. 넷째, 20∼30대의 연령대에서 이동이 가장 활발하게 나타났으며, 연령대별로 지역별 이동이 다르게 나타난다. 또한 학령연령대인 10대의 연령대는 부모세대와의 이동의 연관성을 발견할 수 있다. 마지막으로 요인분석과 군집분석을 통해 대구시 이동권을 분석하였다. 2001년 27개, 2009년 29개의 小이동권이 나타났으며, 이는 다시 각각 4개의 大이동권으로 구분된다. 이동권은 대구시의 계획적인 생활권의 범위를 크게 벗어나지 않으며 나타난다.

The purpose of this study is to derive priorities for individual factors according to the importance of activating The untact performing art (non-face-to-face performing art). Through the results, it will grasp the priorities necessary for dancers and provide basic data to explore new turning points in the dance world in response to the continuous contact era. AHP analysis for dance experts to find out the priorities of the elements to revitalize the untact performing art. Through prior research analysis, the team derived five key attributes that are prioritized for activating the untact performing arts and 20 detailed factors, four for each upper-level factor. The analysis results are as follows. Among the top five items, "national institutional support (0.278)" was the most important item, "activating support projects (0.359), but the result seems to reflect the fact that the dance industry is focusing on support funds. This is because the production of works in the dance world is mainly conducted through public exhibitions or support projects. For example, a system where choreographers select dancers and receive support money if they meet the absolute criteria in auditions, such as the "Dancers Job Market" of the Specialist Dance Support Center, is a necessary support project for dancers. Through this project, choreographers will be able to discover dancers who will appear in their works and receive support from dancers for performances, which will greatly help choreographers and dancers to produce and manage dance performances. On the other hand, the bottom five were "recognition" (0.155), "physical conditions of dancers" (0.160), "explanation of dance works" (0.187), "implementation of the Portrait Copyright Protection Bill" (0.197), and "future-type technical education" (0.199), which ranked lower than the original factors. Dancers tend to immerse themselves in the work itself rather than in the additional elements that support the work, and they judged that even if less important factors were excluded, there would be no significant impact on the work. Of the five top-level items, the lowest importance of "education" was in stark contrast to the results of previous studies (hereinafter referred to as 2015), which put education at the top priority on education. This is because many previous studies on "popularization of dance" and "activation" have judged that "education in dance" is essential to the extent that the necessity of "dance education" is given top priority. Most of the issues raised in previous studies mentioned university dance studies and curriculum. Previous studies have shown that students are not given the opportunity to engage in independent artistry or career coordination related to dance because the current curriculum of the department focuses on training dancers and consists only of sequential exercises for performances. Due to the characteristics of the arts, it is important to learn directly or indirectly on the stage or on the spot, but theoretical education and practical learning based on it should be the foundation. In this way, the educational aspects of dance were mentioned as essential for popularization of dance, but in the survey results of dancers conducted in this study, education itself was not so important. In this regard, it was found that there were significant differences between the recommendations in the paper on dance activation and the results of this paper. The enactment of the Portrait Copyright Protection Bill (0.197), which was the least important of the top five categories, shows that dance art, which was mainly conducted in the field art, has not been legally effective in film productions, but can benefit from the spread of the untact performing art. As the untact performing arts can be stored through sound and video recordings, it is possible that the copyright and plagiarism of the works in question will be easily punished. Face-to-face performances have the characteristics of one-time, and extinction, but the untact performing arts can be preserved so that plagiarism can be clearly judged. Therefore, it is judged that such problems may be improved with the diffusion of the untact industry. In this age of the Fourth Industrial Revolution, the untact system has become an inevitable trend. At home and abroad, dance films and online live broadcasts are revolutionizing the dance industry as a whole, but the reality is very important, and dancers who breathe face-to-face with the audience need a new approach in the untact performance art. Untacts are becoming increasingly widely used, but they also have obvious limitations. There are limits to sophistication, creativity, and diversity, as well as severance of people-to-people relationships, and if a plan to overcome these limits comes up, Untact will be used more effectively to revitalize the dance field. By closely analyzing the current crisis situation and presenting a new perspective on innovation in the dance field, this research focuses on providing basic data for this research. In dance art, in which the characteristics of being on the spot, being on the spot, being on the spot, being on the spot, and being on the face-to-face were particularly important, the encounter between the untact and the dance will require continuous research. Therefore, the important factors presented in this study are all essential factors in dance performance art, but the priorities derived from this study gave us an idea of what should be done first and which factors were relatively less aware of the importance than necessary. I want to conclude this research by analyzing the factors that should be prioritized for the revitalization of the dance field with the untact method applied.

유다혜 공주대학교 대학원 2018 국내석사

뇌전증은 강직 발작, 간대 발작, 강직간대 발작 그리고 결여 발작을 증상으로 갖는 신경 질환이다. 이 질병은 뇌종양, 지주막하출혈 그리고 다른 뇌손상과 같은 후천적 원인뿐만 아니라 환경적 요소 그리고 유전적 요소들에 의해 발병한다. 유전적 뇌전증은 운반체, 수용체 그리고 이온 채널들을 암호화하는 다양한 유전자들 내 돌연변이에 의해 발병한다. 유전 공학 기술의 발달로 뇌전증과 연관되어 보고된 유전자들이 증가하고 있다. 본 연구에서는 엑솜 데이터로부터 1,412개의 뇌전증 관련 유전자들을 분석함으로서 두 개의 돌연변이와 위험 인자들을 동정하였다. POLG2와 LGI1 유전자 내 병원성 돌연변이는 각각 EF14 가족과 EF23 가족으로부터 발견되었다. POLG2 유전자 내 c.694G>A (p.Gly232Ser) 동형접합 돌연변이는 열 증상을 함께 보이는 전신 결여 뇌전증 (EF14 가계) 환자에게서 발견되었다. POLG2 돌연변이를 갖는 환자와 환자의 모친으로부터 3,484 bp 미토콘드리아 DNA 거대결손을 발견하였다. LGI1 유전자 내 c.988C>T (p.Arg330X) 이형접합 돌연변이는 전신강직발작을 보이는 (EF23 가계) 환자에게서 발견되었다. POLG2와 LGI1 유전자 내 돌연변이들은 이전에 각각 미토콘드리아 DNA 결손을 갖는 진행성 외안근마비와 가족성 관자엽 뇌전증을 일으킨다고 보고된 바 있다. POLG2 동형접합 돌연변이와 LGI1 이형접합 돌연변이는 dbSNP, 1000G, ESP, ExAC와 KRGDB에서 보고되지 않았다. 두 돌연변이 위치는 모두 GERP 점수가 높았으며, 이는 다양한 종에서 해당 변이 위치의 높은 보존성을 나타낸다. In silico 분석을 통해 돌연변이가 단백질의 구조나 기능에 영향을 줄 것으로 예측되었으며 (SIFT, PolyPhen2), 단백질의 안정성을 감소시킬 것으로 예측되었다 (MUpro). 뇌전증 위험 인자들은 네 가족들을 대상으로 분석하였다. SLC12A5 유전자 내 c.2855G>A (p.Arg952His) 돌연변이와 PRODH 유전자 내 c.1397C>T (p.Thr466Met) 돌연변이는 각각 전신 강직간대 발작을 보이는 환자와 전신 비정형 발작을 보이는 환자로부터 발견되었다. SLC12A5 유전자 내 돌연변이와 PRODH 유전자 내 돌연변이는 특발성 전신 뇌전증과 프롤린 탈수소효소 결핍증의 위험인자로 보고된 바 있다. 더불어 본 연구는 이전에 보고되지 않은 뇌전증 위험인자로 보이는 후보 변이들을 선별하였다. 본 연구는 엑솜 데이터로부터 1,412개의 뇌전증 연관 유전자 내 돌연변이를 분석하여 두 개의 병원성 돌연변이와 뇌전증 위험인자로 고려되는 후보 변이들을 발견하였으며, 이는 뇌전증의 분자진단 및 맞춤치료에 도움을 줄 것으로 기대된다. Epilepsy is a neurological disorder characterized by tonic, clonic, tonic-clonic and absence seizure. It is caused by not only acquired causes such as brain tumor, subarachnoid hemorrhage and other problems in brain, but also environmental and genetic factors in the etiology of epilepsy. Genetic epilepsies are caused by mutations in a number of different genes, many of them encoding ion channels, receptors or transporters. Development in genetic technology has led to the identification of an increasing number of genes associated with epilepsy. In this study, two pathogenic mutations and several risk factors were identified by analyzing mutations in 1,412 epilepsy-related genes from whole exome sequencing (WES) data. The pathogenic mutations in POLG2 and LGI1 were identified in each of EF14 and EF23 families. A homozygous c.694G>A (p.Gly232Ser) mutation in POLG2 gene was detected in a generalized absence epilepsy patient with fever symptom (family ID: EF14). A patient with POLG2 mutation also had 3,484 bp deletion of mitochondrial DNA (mtDNA) with his mother. A heterozygous c.988C>T (p.Arg330Ter) mutation in LGI1 gene was detected in generalized epilepsy patients with tonic-clonic seizure (family ID: EF23). It was reported that mutations in POLG2 and LGI1 cause each of progressive external ophthalmoplegia with mtDNA deletions and familial temporal lobe epilepsy before. Both of mutations’ sites had high GERP scores that indicate high conservation between other species. POLG2 homozygous mutation and LGI1 heterozygous mutation were not reported in dbSNP, 1000G, ESP, ExAC database and KRGDB. In silico predictions of the effect of mutation about protein structure and function revealed that it is highly likely to be deleterious (SIFT, PolyPhen2), and that the mutant protein has decreased stability (MUpro). Risk factors of epilepsy were analyzed from four families. A c.2855G>A (p.Arg952His) mutation in SLC12A5 and a c.1397C>T (p.Thr466Met) mutation in PRODH were detected in a patient with tonic-clonic seizure (family ID: EF07) and a patient with atypical seizure (family ID: EF13). Each of a SLC12A5 mutation and a PRODH mutation was reported as a risk factor of idiopathic generalized epilepsy (IGE) and Proline dehydrogenase deficiency. This study also selected candidate risk factors for epilepsy, which was unreported before. In conclusion, analysis of mutations in 1,412 epilepsy-related genes from WES data was enable to find two pathogenic mutations and candidate variants as the genetic risk factors for epilepsy. Additionally, this work is expected to help molecular diagnosis and tailored treatment of epilepsy.

Research Objective: The purpose of this study was to investigate the eating habits, vegetable intake status, perceptions, and preferences of some middle school students in Jeonju, and to prepare strategies and basic data for providing meals to improve and increase vegetable intake. Methods: The survey contents were analyzed by investigating general characteristics, eating habits, vegetable intake status and perception, and preference for providing vegetables. Research Results: The following presents the analysis results. The survey subjects were 44.3% of male students and 55.7% of female students, and the average age was 13.31 ± 0.81 years. The body mass index(BMI) obesity of all subjects was within the normal range. 67.3% of the survey subjects were found to be ‘a little bit’ picky depending on the food, and the frequency of eating vegetable side dishes in home meals was confirmed to be ‘3-4 a week.’ As for the types of picky food among the survey subjects, ‘vegetables’ was the highest at 47.7%, and As for the preferred side dishes, ‘meat’ was the highest at 39.2%. 71.7% of the survey subjects’ vegetable preference and avoidance factors were found to be the most disliked ‘bitter taste’, In addition, the texture of vegetables that hate the most was ‘squashy’ at 62.0%. Based on the survey subjects’ scores based on gender and picky eating, ‘eating vegetables will make my body healthy’ was the highest, ‘rice’ was the highest, and ‘stir-fry & roast’ was the lowest. In addition, in terms of the frequency of vegetable intake and vegetable preference, ‘bean sprouts’ were the highest, and ‘eggplant’ was the lowest. What should be improved in the opinions related to the provision of vegetables of the survey subjects was that both men and women had the highest ‘taste’ at 47.0%, and wanted to activate the provision of vegetables (46.0%). In addition, 64.0% of the students were confirmed to have no experience in vegetable consumption education at school. As for the need for vegetable consumption education for the survey subjects, ‘need’ was the highest at 33.7%, and male students had higher demands than female students. As a result, most of the survey subjects seem to have a positive perception of vegetable consumption. Conclusion: Therefore, as the survey subjects showed a positive perception of vegetables, it is believed that if students are given specific nutritional education on the efficacy and importance of vegetables, it will help increase their intake of vegetables. In addition, it is believed that research on the development of recipes that combine various menus by reflecting the preferred vegetables derived from this study is needed.

This study aims to analyze the actual conditions of abusing sports articles on the news services at domestic portal sites and to analyze the characteristics of articles on sports media in these portal sites. We aim to examine the problems of media coverage and suggest future directions for the sports articles. As the first step to achieve the purpose of our research, we selected Naver and Daum Kakao, which are the portal sites with the highest average inflow rate among the domestic portal sites, and we analyzed the actual conditions of abusing by using 6 representative keywords. As the result, Naver had greater amount of abusing articles compared to Daum Kakao, and the following were found with high frequency: “Park Inbi” among the keywords for people, “positive articles” for the keyword related to personality, and “international” articles for domestic and international issues. Based on these researches, our study suggests that it is necessary to analyze the actual conditions of abusing in the sports articles by adding keywords that are representing sports, and the causes and solutions of sports article abusing should be found in the later studies.

RFID용 HB 인증 프로토콜을 위한 태그 인식 기법에 관한 연구

유다혜 호서대학교 2008 국내박사

RFID is a crucial technology in today’s ubiquitous age. However security is becoming a major issue with the increase in the use of RFID. HB authentication protocol is currently under debating and researching to take action against it. HB authentication protocol is lightweight to make up for the low performance of tags However, it cannot be put to practical application due to identification problems with the tags. Hence this paper will propose a complemented HB authentication protocol without the tag identification problem yet retaining its strength of lightweight that could actually be used in reality. RFID기술은 유비쿼터스 시대에 있어 핵심적인 기술로 각광받고 있다. 하지만 RFID기술이 폭넓게 사용됨에 따라 보안문제가 대두되고 있다. 이 문제에 위한 해결책 중 하나로 최근 HB 인증 프로토콜에 대한 연구에 관심이 모이고 있다. HB 인증 프로토콜은 태그의 낮은 성능을 뒷받침 할만한 경량성을 갖추고 있지만 태그의 식별문제에 있어 해결책을 제시하지 못하여 프로토콜의 실용성이 낮다. 본 논문에서는 HB 프로토콜의 단점인 태그식별 문제를 해결하면서 HB 인증 프로토콜의 장점인 경량성을 살려 실질적으로 HB 인증 프로토콜이 상용화 될 수 있도록 보완된 프로토콜을 제안한다.
