지금의 IPTV는 IP기반 방송융합 서비스로서 현재 세계 유명 통신 사업자들을 중심으로 빠르게 발전하고 있다. 하지만 'IP+방송' 이라는 그저 단순한 결합과 부가서비스들의 제한으로 인해 기술의 비효율성이 드러나 있으며, 주로 IPTV서비스를 필두로 현재 콘텐츠에 대한 유출사고가 이루어지고 있다. 따라서 변화된 새로운 형태의 차세대 IPTV서비스와 더불어 그 특성에 맞게 보안 서비스에 대한 요구사항이 필요하다. 본 연구에서는 유무선 통합 환경에서 제공되는 IPTV서비스에서의 안전하고 효율적인 콘텐츠 서비스 제공을 위한 'CAS 적응형 DRM 모델'을 제안하였다. 사용자가 다운로드한 DRM이 적용된 콘텐츠를 안전하고 효율적으로 자신이 소유한 디바이스에서 이용할 수 있는 방안을 제시한다.

The purpose of this study was to examine the relationships between anger expression, social supports, and adjustment to college life among nursing students. A convenience sample of 266 students in two colleges participated in the study. Data were analyzed using t-tests, ANOVA, Pearson correlation coefficients, and multiple stepwise regression. The mean score for adjustment to college life was above average. The mean score for adjustment to college life differed significantly according to students' reasons for applying to college and perceived health status. Adjustment to college life significantly correlated with anger expression and social supports. Multiple stepwise regression analysis showed that anger expression (Anger-Out, Anger-In, and Anger-Control), social supports, and perceived health status explained 27.1% of the variance in adjustment to college life. The study findings suggest that interventions intended to promote nursing students' adjustment to college life should focus on improving anger management, social supports, and perceived health status.

The purpose of this study was to identify the facility adaptation characteristics, and the relationship between facility adaptation and the potential affective factors; ADL, self-efficacy, and quality of care facility, and to identify the affective factors on facility adaptation for elders in long-term care facility. Data were collected from 177 none dementia elders over 65 in 9 long-term care facilities from Jan.2, 2011 to March 15, 2011. The data were analysed through t/F test, correlation coefficient, and multiple regression (stepwise). The major findings of this study were as follow; Facility adaptation shows significant difference from admission decision maker(p=.004), religion(p=.027), and motive of admission(p=.009). And facility adaptation has weakly correlated with ADL and quality of care facility. The affective adaptation factors were decision maker, motive of admission, personal interview, religion, and perceived health status, but showed 22.8% of explanation. Thus the findings from this study could be used as bases for nursing intervention supporting elders' care facility adaptation.

The aim of this paper is to develop a web-based Virtual Learning System for discrete mathematics learning using CAS (Computer Algebra System), The system contains a series of contents that are common between secondary und university curriculum in discrete mathematics such as sets, relations, matrices, graphs etc. We designed and developed web-based virtual learning contents contained in the proposed system based on Mathematia, webMathematica and phpMath taking advantages of rapid computation and visualization. The virtual learning system for discrete math provides movie lectures and 'practice mode' authored with phpMath in order to enhance conceptual understanding of each movie lesson. In particular, matrix learning is facilitated with conceptual diagram that provides interactive quizzes. Once the quiz results are submitted, Bayesian inference network diagnoses strong and weak parts of learning nodes for generating diagnostic reports to facilitate personalized learning. As part of formative evaluation, the overall responses were collected for future revision of the system with 10 university students.

Home care services, this study dependent family resilience and family stress, family adaptation through any route in order to examine the impact the Gwangju JeonNam home care services for elderly dependents, a survey of 203 people was conducted. The study of home care services dependent family adaptation family stress family tension without affecting the direct communication of the factors affecting indirectly through was. Based on the results of these studies look more family stress, family resilience to adapt because it affects family adaptability in order to improve the existing defects to reduce family stress perspective rather than focusing on the strengths of family resilience must be done in terms of the transition is proposed.

This paper proposes the system to manage profiles effectively that are necessary for content adaptation services. The proposed profiles for providing content adaptation services are used in the various services. However, currently, there are lack of the interoperability in profiles due to the different configuration, which is affected by different services. The service providers also spend a lot of operating costs by operating profiles respectively. To solve theses problems, the system which can integrate and manage the various kinds of the profiles is necessary. Based on profile services architecture and the previous profile research to the necessary functions for the proposed integrated management system of profile are derived. The proposed integrated management system of profile supports also the functions such as receiving, processing, saying, managing, providing and supports profiles that are made of RDF form and comply with the CC/PP specification. The metadata constitution technique and dynamic technique for effective content adaptation also are applied. As a result of performance evaluation the proposed techniques improve the performance 4% compared with the previous techniques.

This study aims to analyze the cultural intelligence and it's relationship with cross-culture adjustment satisfaction, and performance, and then, we prove the moderating role of international experience between cultural intelligence and cross-culture adjustment with staying in the host country. An exploratory pilot study was conducted with a sample of 188 Chinese expatriates working in Korean company in Korea. Then, we proved the moderating role of international experience between cultural intelligence and cross-cultural adjustment. The results of this study have three implications for human resource development. First this study expanded the research of CQ up to the area of empirical investigation. Second, the empirical findings also supported an incremental and predictive validity that CQ increased explained variance of cross-cultural adjustment. Third, the moderating role of international experience in this study showed the importance of both CQ and international experience with staying in the host country.

The present study set out to explore the acculturative stress and mental health(depression) of Korean women living in Britain according to socio-demographic factors, social relations and social supports level. 152 Korean women's data were collected and analyzed with frequency, correlation, ANOVA. Analysis revealed that women's acculturative stress and depression level was 2.50(moderate) and 1.66(slightly low) respectively. Acculturative stress level showed correlation with depression level. Among demographic variables, acculturative stress was significantly different from residence period in Britain, marriage and economic state and the level of depression was also different from job and economic state. The group which has frequent relationships with British and high level of social supports showed low acculturative stress. The group has high level of social supports also showed low depression. These findings highlight the importance of concerns and interventions about acculturation and mental health of Korean immigrant women and community services for the new immigrant women to improve their acculturation and mental health.

The purpose of this study was to investigate the effects of marital conflicts on dyadic adjustment and the mediating effects of positive emotion and sex-role attitude. The participants were total 270 middle-aged married people and data was collected from April 12 to June 24 in 2014. The data was collected with structured questionnaire and analyzed with the SPSS 17.0 and AMOS 18.0 programs. Results were as follows. First, marital conflicts had a significant direct effect and indirect effect through the mediation of positive emotion on dyadic adjustment. Second, positive emotion had a significant mediating effect but sex-role attitude did not. Third, The modified model showed a good fitness indices( ${\chi}^2$=38.90 standardized ${\chi}^2$=1.77(CMIN/df), GFI=.97, AGFI=.94, NFI=.98, SRMR=.02, CFI=.99, RMSEA=.05) and explanation power was 88.9%. These results suggest that middle-aged dyadic adjustment can be improved by increasing positive emotion. This study results will be contribute to develop intervention program for enhancement of marital relationship and education program for middle-aged.
