A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance benficiaries selected by simple random sampling from a Dong(Township) in Taegu. Well-trained surveyers mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical aid beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease. In medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferrable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was afford ability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.

The purpose of this study is to investigate the determinants of job satisfaction among care givers. Finding out the determinants of job satisfaction among care givers, the dependent variables were defined 3 groups with 9 sub-factors, such as personal factors of growth needs and self-efficacy, job factors of job diversity, job autonomy, job importance, role clarity and workload, organizational factors of comradeship, education & training. For the study, data were collected form 479 care givers working in 52 care facilities of Chung Nam Province and analyzed them by regression analysis technique using the SPSS 20.0 statistical package. The results are as followings, job diversity, job importance, comradeship, education & training have positive effects on job satisfaction respectively, workload effects on it negatively, but growth needs, self-efficacy, job autonomy, role clarity no effectiveness on job satisfaction. Based on the results of study, theoretical implications are discussed for care givers to promote the job satisfaction and suggested the directions for further study. Further more, the findings provide the basic sources for care giver human resource management in long term care facilities which are suffering from recruiting of care giver, and it also contribute to successful management of long term care insurance system as a meaningful suggestion.

The purpose of this study is to understand attributes, stress and burnout related to job environment of healthcare facilities workers for the aged, care-givers, analyze the effect of these factors on job satisfaction, and improve their organizational task to help advance the quality of life and the healthcare facilities for the aged. A survey was made on 129 care-givers working in the healthcare facilities for the aged(care facilities, in-home facilities for the aged) located in Jeonbuk Gunsan area. This study showed that sub-factors of care-givers' job environment such as human environment, compensation system and job expertise have a significant effect on the job burnout, stress and satisfaction. This means that a well-organized compensation system, which is proportionate to the job expertise and ability for human environment, and achievement of innovative thinking, will make a positive relationship, reduce the job burnout and stress, and improve the job satisfaction at the same time. Compared to the rapid increase of old aged patients for long-term care and care-givers' real role and job in the facilities, the job specialization has to be guaranteed to improve job environment of care-givers as various beneficial workers for welfare - professional workers - and the compensation system needs to be properly systematized according to their job capacity. Consequently, the production and participation of professionals with high self-esteem may raise organizational commitment through the maximization of job satisfaction by the participation and devotion to the organization of more professionals by removing factors, which can reduce the frequent job burn-out and stress of care-givers.

컴퓨터가 다루고 있는 정보의 기밀성(confidentiality of information)을 보호하는 일은 매우 중요하며, 그 중요성은 날이 갈수록 증가하고 있다. 그럼에도 불구하고, 실제로 정보의 기밀성과 무결성(integrity)을 완벽하게 보호해 주는 컴퓨터 시스템은 매우 찾기가 어렵다는 것이 또한 알려진 사실이다. 기존에 존재하는 이론적인 프레임워크들은 기밀성을 표현하기에는 부적절하며, 기밀성 보호를 위한 실제적인 시스템들 역시 이론적인 면에서 충분히 만족스럽지 못하다. 이와 같은 현실에서 타입시스템을 가지는 프로그래밍 언어가 정보 기밀성 보호를 위한 효과적인 방법으로 새로운 관심을 받고 있으며, 상당한 연구가 이 방향으로 진행되고 있다. 본 논문에서는 이제까지 진행되었던 연구들을 중심으로 프로그래밍 언어를 이용한 정보 기밀성 보호의 연구 동향과 주요 과제들을 소개하고자 한다.

개인정보보호가 단순히 개인의 권익에 관한 문제로 국한되지 않고, 기업의 사활을 좌우하는 이슈로 대두되고 있다. 또한 개인정보의 활용과 보호라는 두 가지 상충되는 기업 내 목표와 관련 개인정보보호법이나 규정 준수 등 대내외 요구사항을 만족시켜야 한다. 기업 내 개인정보보호활동의 효과성을 높이기 위해서는 현재 산발적으로 진행되는 개인정보 영향평가 등 단순 기법이나 정보유출방지 솔루션 도입 등의 접근방법으로는 한계가 있으며 새로운 접근방법이 필요하다. 본 고에서는 일상적 관리활동의 하나로서 개인정보보호를 위한 관리체계의 필요성과 관리과정을 소개하며 이를 평가, 지시 및 모니터링 할 수 있는 거버넌스의 목표와 중요성에 대해 기술한다.

The purpose of this study is to find out the effectiveness of drivers' satisfaction over protected and permissive left-turn (PPLT) traffic signal operation. A structural equation model was established for analyzing the effectiveness of various drivers' factors (e.g., personal characteristics, driving attitude, expectation to PPLT, etc.) on the PPLT preference based on questionnaire survey. As a result, the analysis is satisfied with the critical values, such as Q value, RMR, GIF, AGIF, and NFI. The study reveals that PPLT preference increases in case of driver who is male with long social carrier related to transportation affaire and long driving experience without traffic accident involvement. Moreover, PPLT preference increases as the expectation of PPLT to improvement of traffic safety, traffic operation, and traffic environment increases. Therefore, it is recommended that the PPLT should be preferentially operated in urban area of less traffic accidents and the promotion of PPLT be actively conducted for positive effectiveness.

The importance of bumper system lies not only in the styling of vehicles, but also in the protection of vehicles and pedestrians from reasonable impact. In this study, we proceed to search a method for efficient bumper system without using the impact test and the computer simulation to analyze the bumper system. In the process of the research, we proposed the each method that is used to search the shape that satisfy each regulations in first, because bumper's dimensions to satisfy 'vehicle protection' regulations and form's dimensions to satisfy ‘pedestrian protection' regulations are difficult to exist together. After that we proposed the calculate method and design algorithm that is used to search a reasonable point satisfying the two regulations together.

There have been a lot of researches on providing privacy in MANET (Mobile Ad hoc NETwork) using trapdoor, onion, and anonymous authentication. Privacy protection in MANET can be divided into satisfying ID privacy, location privacy, route privacy, and unlinkability between sessions. Most of the previous works, however, were unsatisfactory with respect to location privacy or route privacy. Moreover, in previous schemes, cryptographic operation cost needed to meet the privacy requirements was relatively high. In this paper, we propose a new efficient anonymous routing protocol that satisfies all the privacy requirements and reduces operation costs. The proposed scheme does not use onion or anonymous authentication techniques in providing privacy. We also provide a more accurate analysis of our scheme's efficiency by considering all the nodes involved in the route establishment.
