This study was to investigate the differences of functional health status and medical service experience and needs between general and vulnerable older people in community. This study is a cross-sectional descriptive research. The data obtained through direct visit surveys from November to December 2016. The target population of the study was older people over 65 years old, the final study subjects were 444 older people residing in one district of Seoul. The chi-square test was conducted to confirm the difference in their functional health areas and medical service experiences, and the necessity of medical service utilization in accordance to the social class. In the experience of abnormality in functional health, the vulnerable older people had higher experience in cognitive function, nutrition, hydration, pain, and falling than the general older people. The rate of experience of using medical service to solve the cognitive function problem for general older people was 31.9%, higher than that of the vulnerable older people. In contrast, the medical service utilization needs of the vulnerable older people in the pain management category was significantly higher than that of the general older people. In setting policy of public medical service programs for general and vulnerable older people in community may be differentially developed based on this study. In order to improve the medical accessibility of the vulnerable older people, public medical institutions should be actively supported to overcome obstacles to medical use due to economic barriers.

The purpose of this study is to assess the relationships of alcohol consumption patterns to mental distress and self-rated health. Data of 19,856 adult drinkers over 19 years of age and older from the Korea National Health and Nutrition Examination Survey were evaluated by multivariate logistic regression analysis. Risks of experiencing perceived high stress, depressive symptoms and suicidal thoughts were higher in alcohol use disorder group in male, whereas the risks were higher in both alcohol use disorder and hazardous drinking groups in female, reflecting higher susceptibility to mental distress. In both male and female, former drinkers presented poor self-rated health compared with low-risk drinkers, although no difference was found in the prevalence of mental distress. Specialized mental health management measures for female drinkers are required, and former drinkers are suggested to be assessed separately from never or low-risk drinkers for their physical and mental health status.

The purpose of this research examined the relationship between the level of news usage on Influenza A(H1N1) and media users' behavioral intention toward health protection. Specifically, the study investigated causal relationships among exposure of media information on Influenza A(H1N1) as an independent variable, psychological protection motivation factors such as perceived severity, vulnerability, response efficacy, & self-efficacy as mediated variables and behavioral intention on personal and public health protection as dependent variables using structure equation model analysis. Self-reported questionnaires were administrated to 460 college students. The result indicated the followings. First, the level of news usage on Influenza A(H1N1) was not statistically significant on influencing behavioral intention toward personal and public health protection. Second, perceived severity, vulnerability, and self-efficacy were significant variables on behavioral intention toward personal health protection whereas perceived vulnerability and response efficacy were significant on public health protection. The function among factors in protection motivation theory is dependent upon whom protected from illness.

The purpose of this study is to clarify the concept of the frail elderly and to obtain theoretical evidence. The research method was conducted using the basic principles for conceptual analysis of Walker and Avant(2005). As a Result of a review of the literature about how to utilize the concept of a frail elderly, frail elderly might be in the intermediate state of health and disease. They can be defined as physically vulnerable in the sarcopenia, inflammation, insulin resistance, and preceding advanced disease, lead to hospitalization, falls, disability, and death. The attributes were physiological, psychological, and socio-environmental and economic factors, so they had multidimensional factors. They were required the assist daily living of another person. Also, their attributes had decreased the amount of recovery time and degree, and exhaustion. The attributes of frail elderly consisted of these facts: dynamic process, multidimensional factors, dependency, vulnerability. The frail elderly was a dynamic process that involves the possibility of change to health and disease, and include physical, mental, cognitive, and social environmental factors. In addition, the frail elderly was difficulty in daily life, physical vulnerability and difficulty in adaption. In conclusion, frail elderly as defined by the results of this study will contribute to the foundation of health care systems, including community visiting nursing to understand the level of frail elderly and systemic management to do not go into long term care.

P. Kocher에 의해 DPA 공격이 소개된 이후 이를 방어하기 위한 연구가 활발하게 진행되고있다. 그에 대한 일환으로 블록암호알고리즘 구현 시 소프트웨어적인 대응방안으로 마스킹 기반의 대응기법이 많이 사용되고 있으며 이는 1차 DPA 공격에 안전한 것으로 인지되어 왔다. 본 논문에서는 부주의하게 구현된 마스킹 기반의 대응기법이 2차 DPA 공격이 아닌 1차 DPA 공격에도 취약한 사실을 증명하였으며 이를 실험을 통해서 검증하였다.

The purpose of this study is to design the easy payment service research model and to find the influencing effect on the intention for the reuse of easy payment service by analysing the factors such as the social influence, the promotion condition, the security and the convenience as UTAUT model has. Also the research model employs the trust and the user satisfaction as parameters. The result shows that even though people feel the trust due to the convenience by the social influence, it has a negative influence on the user satisfaction if the risk recognized in the easy payment service and the weakness in the security are anticipated. The results of this study are academically meaningful as they established the research model for the easy payment service and the theoretical basis of the easy payment service area; they have provided the various practical implications.

An anonymous asymmetric fingerprinting protocol combined with watermarking techniques, is one of the copyright protection technologies keeping both right of a seller and that of a buyer, where a seller and an anonymous buyer perform such a protocol that employs various cryptographic tools in order that the seller does not know the exact watermarked copy that the buyer receives, while inserting an invisible non-removable fingerprint i.e., each different unique watermark, into each copy of the digital content to be sold. In such a protocol innocent buyers are kept anonymous during transactions, however, the unlawful reseller is unambiguously identified with a real identity as a copyright violator. In 2007, Yong and Lee proposed an anonymous asymmetric fingerprinting scheme with trusted third party. In this paper we point out the weakness of their scheme such as: the buyer with intention can remove the fingerprint in the watermarked content, because he/she can decrypt the encrypted fingerprint with a symmetric key using man-in-the-middle-attack; a real identity of a buyer can be revealed to the seller through the identification process even though he/she is honest. Furthermore, we propose an improved secure and efficient anonymous asymmetric fingerprinting scheme which enables to reduce the number of communication between the participants.

전 세계적으로 대형 재난의 발생으로 인해 사회문화적 관습이나 신체조건 등의 차이로 남성보다 여성의 피해가 크다는 사실들이 다양한 사례와 연구를 통해 보고되었고, 개발도상국은 여성의 피해가 큰 반면에 선진국은 여성들의 재난 안전 및 교육 관리에 적극적인 참여를 통해 전반적인 대응 능력을 보일 수 있다는 연구들도 존재한다. 우리나라의 경우에도 빈번하게 자연 재난이 발생하고 있지만, 실제로 재난 안전 인식에 대한 성별 분석을 하기 위한 자료가 부족한 상황이다. 그러므로 본 연구에서는 이와 같은 문제점을 파악하기 위해 한국 국민 남녀 489명을 대상으로 재난위험인식에 대한 설문을 실시하고, 거주지 주변 발생 가능한 재난을 인지하고 있는지, 대피소의 위치를 인지하고 있는지, 안전 관리 교육 경험이 있는지 등의 문항으로 구성하여 실시하였다. 본 연구의 목적은 국민들의 재난 안전의 위험도에 대한 인식 수준이 어떠한지 분석하고, 영향 요인을 탐색 하는 데에 있다. 조사결과 안전취약계층은 스스로 대피 하는 데에 있어 큰 어려움이 있으며, 이중 여성은 남성에 비해 안전교육과 훈련의 접근성이 적음에 따라 위험도가 더 큰 것을 확인 할 수 있었다. 그럼에도 불구하고, 재난 및 안전관리 교육 및 훈련에 참여하고자 하는 의지는 남성과 여성의 차이가 없었다. 본 연구를 기반으로 재난 안전교육의 필요성을 가지고 재난 안전 시뮬레이션 프로그램이 구축되는 필요성이 있다고 사료되어지고, 미래에 자연재해 발생 시 문제점을 파악하고 인명 피해 감소가 될 전망으로 기대가 된다.
