장은아,표용수,Jang, Eun-Ah,Pyo, Yong-Soo 영남수학회 2009 East Asian mathematical journal Vol.25 No.3

In this paper, we conduct a questionnaire survey on the actual conditions and the test on the basic scholastic ability of the students who register for the course, Introduction of Business Mathematics. We want to find the ways to improve the teaching-learning methods for this course. Especially, the registered students have difficulties in the following the course because they have not studied Calculus in their high school. So we give them several assignments on the Webwork system, an internet based homework management system, and analyze its effect on the students' scholastic achievement. And we propose a teaching-learning method suitable for the course.

소수지만 사회에 항상 존재하고 불편함을 안고 살아가야 하는 사람들은 장애를 가진 사람들일 것이다. 그들은 항상 소외되어 사회의 한 일원으로 자신들의 권리를 정당하게 주장하는 것조차 꺼려왔다. 그래서 항상 숨고, 피하고, 자신들만의 사회를 만들어 지낸다. 덕분에 그들과 비장애인들과의 거리는 점점 더 멀어지게 되고 따라서 더 큰 소외감과 이질감이 그들을 가두는 반복적인 현상이 나타난다. 이를 해결하기 위해 모션인식을 통해 글자로 바꿔주는 시스템을 적용한 실시간 통역 앱 개발을 연구 중에 있다. 때문에 이 앱이 청각장애인들이 꼭 필요로 하는 것인지 니즈 조사가 필요하여 청각장애인들과의 인터뷰를 하기로 했고, 대상은 시립 서대문 농아 복지관에서 프로그램을 이용하거나 소통을 하는 청각장애인을 타겟으로 정하였다. 이를 토대로 앱 개발에 있어 가장 필요한 부분이 무엇인지 분석하고 연구하여 GUI 적용에 도움이 되고자 하였다. Hearing-impaired person has difficulty to opinion his or her proper right from surrounding people`s eyes and prejudice. Therefore, they always hide, avoid and make their society for themselves. As a result, disabled people grow away from the main stream and confined themselves. Therefore, I wanted to develop a mobile application to solve communication method among the hearing-impaired people and the normal. I surveyed and interviewed hearing-impaired people at the municipal seodaemun deaf community welfare center in order to get their insights. I analyzed and studied their needs to apply to the GUI design guidelines.

The purpose of this study was to determine the effects of the service quality of boxing clubs on the switching barriers and customer loyalty. For this purpose, data were obtained from 495 persons in a population consisting of boxing club customers in Gyeonggi Province as of 2014 and were then processed by frequency analysis, factor analysis, reliability test, correlation analysis, and multiple regression analysis using an SPSS 18.0 program. The following conclusion was drawn: First, as for the effects of the service quality of boxing clubs on the switching barriers, the functional quality among the sub-factors of the service quality positively affected switching costs and the technical quality had the greatest positive impact on interpersonal relationships, followed by the functional quality. In contrast, the technical quality negatively affected alternative attractiveness. Second, as for the effects of the service quality of boxing clubs on customer loyalty, the technical quality among the sub-factors of the service quality had the greatest positive impact on customer loyalty, followed by the functional quality. Third, as for the effects of the switching barriers of boxing clubs on customer loyalty, interpersonal relationships among the sub-factors of the switching barriers had the greatest positive impact on customer loyalty, followed by switching costs. In contrast, alternative attractiveness negatively affected customer loyalty.

This study conducts a site survey and an attitude survey to visitors on the environmental explanation status on Mountain Odae National Park. According to the result of the survey, we found problems such as insufficient capability of commentators, heavy workload during the peak season and indifference of visitors, and simplification of programs. In order to settle such issues, the followings are suggested. 1) Conduct a certification for environment commentators and establish an institute and a system to certify the qualification and capability of environment commentators. 2) Expand the number of environment commentators to resolve the over workload during the peak season. e.g. association with the forest commentators of Forest Service. 3) Differentiation of environmental explanation according to the audience ages. e.g. program reorganization respectively for childhood, youth and middle-aged, and elderly.

이계림(Lee, Kye Rim),장은아(Jang, Eun Ah),김승인(Kim, Seung In) 한국디지털디자인협의회 2013 디지털디자인학연구 Vol.13 No.1

본 연구는 대표적 모바일 라이브 스트리밍 애플리케이션으로 이용되는 아프리카 TV(Afreeca TV)와 유스트림(USTREM)의 사용성을 평가하여 시청과 방송의 편리성을 도모하고 개선하는데 이의가 있다. 연구 방법으로 문헌연구와 사용성 평가를 실시했으며 사용성 평가는 4인의 전문가가 참여하는 휴리스틱 평가 방법 (Heuristic Evaluation)을 수행하였다. 또한 30인의 사용자에게 설문조사를 통해 라이브 스트리밍 애플리케이션의 선호도와 주 사용 기능에 대한 차이를 분석하고 불편한 점과 개선 사함에 대한 의견을 인터뷰하였다. 휴리스틱 사용성 평가는 아프리카TV와 유스트림 시청 시 23개와 6개, 방송 측면에서는 각기 14개와 0개의 문제점이 도출되었으며, 아프리카 TV는 사용성과 매력성의 원칙, 유스트림은 검색성의 원칙과 관련된 문제가 있는 것으로 나타났다. 사용자 인터뷰 결과 아프리카 TV 사용자는 방송 영상을 저화질 또는 고화질로 선택할 수 있는 기능과 콘텐츠 카테고리의 다양성이 부족하디고 답했다. 유스트림의 사용자는 검색할 정보를 세분화할 수 있기를 원했다. 본 연구의 결과는 추후 모바일 라이브 스트리밍 애플리케이션의 사용성 증대를 위한 개선 방안 모색에 참고 자료로 사용될 수 있을 것으로 기대된다. As the world"s fastest-growing, a range or devices such as smart phones and tablet PC are widespread. So people from all over the world are available on the mobile applications and utilize live streaming service because can be enjoyed high-definition in real time. In this study, we performed usability comparative analysis of two different live streaming applications. The Afreeca TV and the USTREAM applications were targeted. In this study, we does literature research and usability evaluation methods. We performed Heuristic evaluation method that participation of the 4 experts and in-depth interview that participating 20 users in accordance with the six kinds of usability principles. Usability evaluation results, Heuristic usability evaluation announced when watching Afreeca TV and USTREAM has occurred 23 problems and 6 problems. And then, a part of broadcasting has occurred 14 problems and 0 problems. So we conducted classification and analysis by 5 different screen components. Afreeca TV problem was Usable, Desirable and USTREAM problem was Findable. The results of in-depth interview showed that Afeeca Tv users expect the ability to select low or high quality definition and said that the lack of diversity of contents categories and USTREAM users wanted segmenting the information what they want to search. We expect improvement of the usability for live streaming mobile application for using the references or improvement.

Purpose: This study aimed at understanding terminal care provided in nursing homes. Method: An interview survey with staff in charge of terminal care was conducted in 97 nursing homes using questionnaires. The questionnaire was reviewed by 3 experts and pretested at 5 facilities. Data were analyzed using descriptive statistics, chi-square test, and Fisher's exact test. Result: Dyspnea was the most prevalent symptom predicting death. The most prevalent services were vital sign check for physical care, providing services by talking despite an unconscious state for psychosocial care, and respecting the faith of the elder for spiritual care. Employment of a registered nurse showed a significant difference in tube feeding (p=.035), analgesic administration (p=.022), informing the elder of end-of-life state (p=.020), helping an elderly person say good-byes through a visit with friends and acquaintances (p=.023), and helping express feelings related to death (p=.002). Lack of service was noticed for elderly resident, family, and staff after death of an elder. Problems related to terminal care were indifference of family members, difficulty in obtaining medical prescription, difficulty in predicting death, and so forth. Conclusion: Terminal care must be improved by making specific guidelines and it must become a part of nursing home evaluation.

In this study, stability of 4 sulfur compounds (H₂S, CH₃SH, DMS, and DMDS) was investigated for up to 96 h (at 6, 12, 24, 48, 72, and 96 h time points). For these experiments, each sulfur standard was prepared at 10 nmol/mol in a 10 L sampling bag (Teldlar bag). To investigate the stability of the sulfur compounds, regression analysis was applied to the data obtained by the concentration reduction over time at the 95% confidence level. According to regression analysis, the concentration of sulfur compounds in 48 h had statistically significant difference (P-value < 0.05) from stability of 4 sulfur compounds (H₂S, CH₃SH, DMS, and DMDS). The results also indicated that the heavy sulfur compounds (DMS and DMDS) tend to show more rapid concentration reduction than lighter sulfur compounds (H₂S and CH₃SH). This study can be used to improve the reliability of analysis by judging quantitative concentrations of sulfur compounds when controlling odor-polluted areas.
