정은영,제회복,전홍기,윤재득,지영미,천두성,조해월,장경립,Chung, Eun-Young,Je, Hee-Bok,Jun, Hong-Ki,Yoon, Jae-Deuk,Jee, Young-Mee,Cheon, Doo-Sung,Cho, Hae-Wol,Jang, Kyung-Lib Korean Society of Life Science 2002 생명과학회지 Vol.12 No.1
Development of a rapid method possessing the requisite sensitivity and specificity for virus monitoring is necessary for protection of the shellfish-consuming public. Oysters tissue usually contains virus particles in relatively small concentrations along with various other substances that can interfere with detection steps. Therefore, the critical point concerning the detection of viruses in shellfish tissues resides in the processing of samples. The current study demonstrated the possibility of purifying small amounts of virus particles at the interface of a 10/50% sucrose gradient after a single round of sucrose gradient ultracentrifugation. We could detect HAV and poliovirus simultaneously from oyster tissues by using two different sets of primer. Furthermore, the method showed a high level of virus recovery rate (>95%) as determined by plaque assays of the final samples. Taken the advantages of the simple and sensitive methods, it was possible to detect 2 pfu of HAV in 5 g of oyster digestive tissues within 24h.

한국 노인의 여가 시간 좌식활동 관련요인 차이 : 도시 및 농촌 지역 비교
정은영(Chung, Eunyoung),김미정(Kim, Mijung) 한국노인간호학회 2020 노인간호학회지 Vol.22 No.3
Purpose: The purpose of this study was to explore individual, interpersonal, and environmental correlates associated with excessive leisure-time sedentary behavior among older Korean adults residing in urban and rural area. Methods: Using data from 2017 National Older Koreans involving 10,052 (urban=6,912, rural=3,140) participants,we performed multivariate logistic regression analysis to calculate the odds ratios of excessive leisure-time sedentary behavior (≥5 hours per day) for each individual, interpersonal, and environmental factors, stratified by residential area. Results: Excessive leisure-time sedentary behavior was associated with several individual and interpersonal factors including number of comorbidity, exercise time, work time, and neighborhood relationship for the whole sample. Access to facilities was found to be a significant correlate only for the participants in rural area.Conclusion: The findings showed that excessive leisure-time sedentary behavior was associated with not only individual factors including socio-demographic, health status and behavioral characteristics but also interpersonal factors such as relationship with neighborhood. Furthermore, it should be noted that the environmental factor was also important to older adults residing in rural area. Intervention programs to reduce sedentary time of older adults may be more effective if they take these factors into account.

지방의료원의 성과분석: Data Envelopment Analysis와 패널분석
정은영 ( Eun Young Chung ),서영준 ( Young Jun Seo ),이해종 ( Hae Jong Lee ) 한국보건행정학회 2015 보건행정학회지 Vol.25 No.4
This study aims to examine the performance of public municipal hospitals through the analysis of data envelopment analysis, efficiency, profitability, and publicness by using panel data during period from 2006 to 2010. The main findings of the study are as follows. First, as a result of efficiency analysis during the period from 2006 to 2010, it was revealed that the number of staff by each job category, labor cost ratio, the number of operating beds need to be decreased. Second, the performance data represented by the indicators of efficiency, profitability and publicness were complementary and showed a tendency of being increased or decreased in same direction. Third, from the result of panel analysis, the efficiency was mainly influenced by the structural factors, while the profitability was influenced by managerial factors, and the publicness by medical environment. In conclusion, in order to enhance the performance of public municipal hospitals in Korea, it is important to harmonize the effort for effic ency, financial and policy support by central and local government, and the continuous participation of community residents.

신입 및 경력 비서의 교육 개선을 위한 한국, 미국, 일본의 비서 교육 프로그램 분석
정은영(Chung, Eun-young),조덕주(Jo, Dukjoo) 한국비서학회 2016 비서·사무경영연구 Vol.25 No.1
이 연구의 목적은 한국, 미국, 일본의 신입 비서와 경력 비서 교육 프로그램을 비교 분석함으로써 국내 비서 교육을 위한 개선 방향을 탐색한 것이다. 분석 준거는 교육의 체계, 프로그램의 목적, 프로그램의 내용이다. 연구결과, 첫째, 비서 교육 체계에 있어서 한국의 비서 교육은 비서유형이 주로 업무비서인 반면, 미국과 일본 대학의 경우에는 비서유형을 보다 전문화・다양화하고 있으며, 경력비서의 경우도 업무수행능력 제고 및 경력개발을 위해 다양한 교육 참여 기회가 제공되고 있다. 둘째, 프로그램의 목적을 보면, 한국과 일본은 지식․기능․태도 모두를 강조하고 있는데 비해, 미국은 비서의 전문성 제고라는 목적 하에 지식과 기능이 보다 강조되고 있다. 셋째, 프로그램의 내용을 보면, 일본과 미국의 경우 교육 목적에 따라 이에 적합한 교과목 들이 제시되어 있다. 즉, 일본의 경우 인성을 중시하는 교육목적에 적합한 교과목들이 제시되어 있고, 지식․기능․태도 관련 교과목들이 균형 있게 제시되고 있으며 미국의 경우도 비서의 전문성 제고라는 목적에 적합한 교과목들이 제시되어 있다. 이러한 연구결과를 토대로, 비서 교육 체계의 측면에서는 신입과 경력 비서 교육 체계의 다양화, 목적의 측면에서는 비서 교육의 명확한 목적 설정 및 인문적 소양의 강조, 내용의 측면에서는 목적 달성에 적합한 교과목의 제공 및 기능․태도․지식 관련 교과의 균형 있는 개설 등의 시사점을 제시하였다. This study aims to analyze the educational programs of entry-level and experienced secretaries in Korea, USA, and Japan and to explore the desirable directions of improvement of secretarial programs in Korea. A comparative analysis is conducted based on three criteria: the structures, purposes and contents of the programs. First, from the viewpoint of their structures, the secretarial education programs in the USA and Japan are more varied and have more professional characteristics than those in Korea. Second, in Korea and Japan, their purposes are well established focusing on knowledge, skills and attitude in a balanced way. Specially, in Japan, professional attitudes are more emphasized than in Korea. In the USA, the development of professional skills is stressed as the major purposes of the secretarial program. Third, the adjustment of the program contents(subjects) according to the purpose is found in all three countries. That is, in Japan, many subjects are included which help to develop the attitude of a professional secretary, and, in the USA, various subjects are developed to foster their competences.

마이크로 셀룰러 네트워크에서의 CRSVP기반 QoS 보장 기법
정은영(Eun-Young Chung),박상윤(Sang Yun Park),엄영익(Young Ik Eom) 한국정보과학회 2002 한국정보과학회 학술발표논문집 Vol.29 No.2Ⅲ
이동 컴퓨팅 환경에서 양질의 멀티미디어 서비스를 제공하기 위해서는 트래픽에 대한 QoS가 보장되어야 한다. 그러나 기존의 자원 예약 기법은 유선 네트워크를 위해 설계된 것이므로 무선 이동 네트워크에서의 QoS 보장 문제를 상당 부분 해결하지 못하고 있는 실정이다. 또한 최근에는 마이크로 셀들로 구성된 네트워크가 증가함에 따라 빈번한 핸드오프로 인한 전송지연 문제와 이동호스트(MN: Mobile Node)의 위치 이동을 신속하게 제어해야 하는 문제 등이 발생하고 있다. 따라서 이러한 마이크로 셀룰러 환경에서는 기존의 Mobile IP와 RSVP 연동기법을 사용하는 것만으로는 한계가 있다. 본 논문에서는 마이크로 셀룰러 네트워크에서 QoS를 보장하기 위해 CRSVP(Cellular RSVP Protocol)라는 새로운 프로토콜을 제안한다.

Objective : The number of geriatric hospitals and long-term care facilities had been rapidly increased during the past ten years. However, the characteristics of regional distribution for the organizations were not analyzed yet. This study purposed to analyze the spatial characteristics of geriatric hospitals and long-term care facilities in Korea, and analyzed the relationships between their locations and socio-demographic features of regions. Methods : The locations of organizations were identified based on the data from the Ministry of Health and Welfare and the Health Insurance Review and Assessment Services, and geocoding method was used for the analysis. The number of geriatric hospital was 1,215 and the number of long-term care organizations was 4,184. Statistical analysis was conducted based on the City, Gun, Gu administrative regions (N=299). Number of population over 65 years, number of employees, number of business, and number of vehicles per capita variables of regions were included in the analysis. Along with the Ordinary Least Square (OLS) regression analysis, Geographic Weighted Regression (GWR) analysis was performed. ArcMap v10.2 was used for the spatial analysis. Results : The geriatric hospitals and long-term care facilities were more likely to locate in urban areas. In OLS analysis, number of population over 65 years and number of vehicles per person were significant in explaining the distribution of organizations. GWR showed better model performances compare to those of OLS. The coefficients of number of population over 65 years and number of vehicles per person showed different directions depending on regions in geriatric hospitals after GWR analysis. Conclusion : These results suggests that geriatric hospitals were not regionally equally distributed in Korea according to the socio-demographic factors. Further study will be required to quantify the unequal distribution of organizations for older people, and to develop policy interventions to improve their accessibility to care services.
