일반적으로 자료의 효과 연속형인 경우 분산분석과 이산형인 경우 분할표 카이제곱 검정을 통계적 분석방법으로 사용한다. 다차원의 자료에서는 계층적 구조의 분석이 요구되어지며 자료간의 인과관계를 나타내기 위해 통계적 선형모형을 채택하여 분석한다. 선형모형의 구조에서는 자료의 정규성이 요구되어지며 일부 자료에서는 비 선형모형을 채택할 수도 있다. 특히, 설문조사 자료 구조는 문항의 특성상 이산형 자료의 형태가 많아 모형의 조건에 만족하지 않는 경우가 종종 발생한다. 자료구조의 차원이 높아질수록 인과관계, 교호작용, 연관성분석 등에 다차원 범주형 자료 분석 방법을 사용한다. 본 논문에서는 확률분포의 계산을 이용한 베이지안 네트워크 모형이 범주형 자료 분석에서 분석절차를 줄이고 교호작용 및 인과관계를 분석할 수 있다는 것을 제시하였다.

Efficient recovery assistance for individual households is one of the inevitable issues in management after a disaster. Discussion on how the assistance should be provided to them, however, has been put aside whereas amount or contents of it have been disputed every time a disaster happens. Public support system in a time of disaster in Japan is very complicated because many laws are related to recovery support and each law covers just a part of total recovery needs of affected household. It is difficult to see whole picture of the system for affected households. Therefore, households must have many interactions with various sections in charge of particular assistance service to know the contents of each assistance and requirements to receive it to decide combination of supports they use. It is crucial for efficient recovery assistance operation to manage those customer relations since considerable part of troubles in individual recovery came from failure in each interactions caused by lack of common understanding on each recovery process between them. In this paper, I want to introduce how support system in Japan is fragmented, a case of Anamizu town which adopted a customer-oriented framework of information management system for their assistance operation after Mar. 2007 Noto peninsula earthquake and what was learned from the case.

The central government has implemented policies to strengthen the competitiveness of small and medium sized cities for balanced development at the national scale. However, since it is often difficult to enhance the competitiveness through partial projects of each jurisdiction, many local governments collaborate at the regional scale. This suggests that a regional approach is important for the management of small and medium sized cities. On the one hand, the concept of network city suggests that various functional networks can affect the growth of small and medium sized cities. Given this background, the purposes of this study are to delineate regional boundaries at national scale and identify their relations of growth by using functional network and Moran's I index. The study uses the Markov-chain model and cluster analysis to delineate the regions, and Moran's I is employed to identify the relations of growth. The results show that interactions between jurisdictions through networks could be crucial factors for growth of small and medium sized cities, while the networks based on passenger travel and freight movement have different implications. The results suggest that policy makers should not only consider local level investments, but also take the characteristics of networks between cities into account for achieving balanced development and developing regeneration policies.

Densities (${\rho}$), Viscosities (${\eta}$) and ultrasonic speeds (u) of pure acetophenone (AP), propiophenone (PP), $p$-methyl acetophenone ($p$-MeAP), $p$-chloroacetophenone ($p$-ClAP) and those of their binary mixtures with $N$-ethyl aniline ($N$-EA) as a common component, were measured at 303.15 K over the entire composition range. These experimental data were used to calculate the excess volume $V^E$, deviation in ultrasonic speeds ${\Delta}u$, isentropic compressibility $K_s$, intermolecular free length $L_f$, acoustic impedance Z, deviations in isentropic compressibility ${\Delta}K_s$, deviation in viscosity ${\Delta}{\eta}$ and excess Gibbs free energy of activation of viscous flow ($G^{*E}$) at all mole fractions of $N$-ethyl aniline. These parameters, especially excess functions, are found to be quite sensitive towards the intermolecular interactions between component molecules. Theoretical values of viscosity of the binary mixtures were calculated using different empirical relations and theories. The relative merits of these relations and theories were discussed. The experimental results were correlated by using the polynomial proposed by Redlich-Kister equation.

Purpose: The use of video-recording offers important advantages in observing and assessing the relationship between specific behaviors in health care settings. The purpose of this systematic review is to investigate and synthesize the methodological characteristics of studies using video-technology for measuring interactions with the older persons with dementia and staff in long-term care facilities. Methods: We searched Medline, Embase and CINHAL databases for published articles in English using a video-recording method for both staff and the residents with dementia. Quantitative research design studies (e.g., descriptive or experimental studies) were included. Results: Among 5,605 searched papers, a total of 20 studies were selected for this review. Situations of video-recording were providing personal care (n=12), mealtime (n=6), and conversation (n=3). Concepts measured by video-recording were classified into two groups: 1) Staff [care practice by staff (n=13) and communication by staff (n=11)] and 2) residents [communication by resident (n=4), activities of daily life function of resident (n=8), and behavioral and psychological symptoms of dementia (n=10)]. Conclusion: This review demonstrates that video technologies are actively used to evaluate the relationship between quality of care and health outcomes of the elderly with dementia in many international nursing studies. This study provides the foundation for a future research using video-recording technologies to examine the interactions and relationships between staff and the residents in Korean long-term care settings.

본 연구의 주제는 정보의 관계를 사용자 중심으로 시각화하는 것이다. 생활 속에서 제공되는 대부분의 정보들은 보이지 않는 연결성을 가지고 있다. 이런 정보들의 공통적인 특성 및 관계의 분석를 통해 정보의 중요도를 측정 할 수 있고, 정보관계의 전체적인 특성을 파악할 수 있다. 사회 연결망 이론은 인간관계에 초점을 맞추고, 사회의 각 개체 간 관계를 분석하여 도식화하는 여러 방법론이 제시되어 있다. 본 연구는 제한된 사회라고 볼 수 있는 그리스신화를 소재로 선정하여 등장인물들 간의 관계를 파악하는데 사회연결망 분석법을 적용하였다. 하지만 시각화 측면에서 볼 때 현재 제공되는 사회 연결망 분석 도구는 사용자를 고려한 디자인 부분이 배제되어 단순히 정보를 일방적으로 보여준다는 한계를 지니고 있다. 미톨로지아는 사용자가 정보를 파악하는데 좀 더 효과적이고 용이한 시각적인 구성을 가진 모델을 제시하고자 했다. 사회 연결망 분석법으로 그리스 신화의 인물들이 가진 신분, 출현 빈도, 감정관계 등을 수치화하여 인물의 연결성을 분석하였다. 또한 정보와 사용자 간의 상호작용 기능을 제공함으로써 사용자의 이해도를 높였다. 기본 인터페이스는 인물노드에 쉽게 접근할 수 있도록 4가지 분류에 의한 인덱스의 형태를 가지며, 인물 간의 세밀한 관계는 선택에 의한 줌-인(zoom in) 기능을 통해 볼 수 있다. 이는 기존의 필터링 기능과는 달리 직접 관련된 정보 이외의 정보들은 감추어줌으로써, 사용자가 보고자하는 인물 관계만을 빠르고 직관적으로 파악할 수 있도록 해준다. 미톨로지아는 개괄적인 관계를 보여주는 레이아웃과 부분적이며 상세한 정보를 파악하기에 적합한 인터랙션 방법을 동시에 제공한다.

Purpose: 'The purpose of the present study was to understand students' experiences from their standpoint, to identify relevant variables and to examine into their relations by analyzing and describing what phenomenon 'nursing students' visiting ambulatory bathing service' is, what are the reasons for the phenomenon, and what interactions are in the phenomenon. Method: The subjects were thirteen students. Data were collected through in-depth interviews and analyzed by Strauss and Corbin's analysis method. Result: With regard to ambulatory bathing service, participants responded 'lack of education', 'inexperienced personal relations' and 'disappointment with recipients families'. They recognized 'burden' and 'compassion'. The intensity of generated 'burden' and 'compassion' was determined by volunteering persons, the degree of health care service, recipients' response and interaction of climate. When 'burden' and 'compassion' were generated, participants selected their own coping strategies. Strategies in the situation of 'burden' and 'compassion' were significantly influenced by 'burden' and 'compassion' and structural situation - 'mutual relation structure,' 'volunteers' capability,' 'the degree of volunteering guidance,' 'community participation,' 'recipients' environment,' 'information sharing,' 'special vehicle equipment' and 'economical burden.' Strategies include' service training,' 'receiving volunteering training,' 'preliminary service preparation,' 'volunteering.' 'connection to local medical center,' 'intention,' 'information sharing,' 'passive response to recipients' appreciation' and 'the understanding of publicity'. The results of selected 'burden' and 'compassion' are described with 'worthiness' and 'cohesion' as follows. Conclusion: This study is significantly meaningful in that it examined bathing service welfare in its initial stage. There are not much outcome from previous studies. However. it is meaningful that this study intended to develop theories on the nature of experiences and the relations among concepts derived from the visiting ambulatory bathing service process of nursing students. Professors who taught social volunteering in universities understood the experience of nursing students who did the visiting ambulatory bathing service. Consequently, professors will provide an effective instruction to enable these students to carry out visiting ambulatory bathing services efficiently in order to meet demands when they conduct the services. For the volunteering service activity in major-related fields among college students' social volunteering activities, they recognized the necessity of systematic education and preparation.

Korea and China are neighboring countries with close contacts in many areas from long time ago, and have shared interests in maintaining peace and stability on the Korean Peninsula, and in deepening economic relationship which has been mutually complementary in their nature. Therefore their bilateral relations has been developed at a remarkable pace to the extent that it can't be better than now. However, the differences in their responses to North Korean nuclear test and ensuing long-range ballistic missile test-fire and the Chinese strong concern on the possible deployment of THAAD (Terminal High Altitude Air Defence) anti-missile system in Korea show that there are some weaknesses in their relations. For example, Korea is not still confident that China would fully implement the sanction measures contained in the UNSC resolution and I argue that Chinese proposal of parallel negotiation of the denuclearization and the replacement of Korean armistice with the Peace Agreement is not much persuasive. In THAAD issue, if Korea comes to conclusion in the future that THAAD is the most effective way to counter North Korean threats, Korea should make every efforts to assure China that Korea-US alliance is not targeting China, and the THAAD is a defensive system, not damaging Chinese security. In the longer-term, deepening strategic distrust and competition between the US and China in this part of East Asia, changing nature of economic cooperation between Korea and China, and the revival of 'great country mentality' by Chinese people together with the rising nationalism in both Korea and China would cast shadow on Korea-China relation in the years ahead, unless properly handled. In this regard, I suggest that the security communications between the two countries be further strengthened, and the tri-lateral dialogue channel be established among the three countries of Korea, the US and China, particularly on North Korean issues. I also suggest the new pattern of economic cooperation be sought, considering the changing economic environment in China, while strengthening the efforts to understand each other through more interactions between the two peoples.

Rapidly aging society extends the span of aged life of the elderly people longer than before and this trend raises the issue of holistic health of the aged including their physical, psychological and social health making it necessary to study for environmental development to support this trend. This study intends to explore the direction of residential planning to support the deterioration phenomenon of social networks due to aging. Social networks here are treated as basic conditions for social health. This study researched the diverse types of elderly housings in preparation for the aged society and their spatial characteristics, social affordance characteristics and their potentials for social interactions from the viewpoint of their social relations. literature studies with contents analysis method was used. The results of this study were arranged primarily according to the characteristics of social relations by types of housings. Socially integrated types of housings can be found as inclusive housing type as they have both social characteristics that can be found in houses in general and the elderly housings, they should be considered as desirable types in Korea where collective houses are most popular. Form the existing housing plans housing plan direction should move toward socially integrated housing plans that can protect the elderly people collectively and the direction of housing plans here means the direction from more macro-perspective viewpoint. Therefore, the results of this study are meaningful in adding interpretation from the viewpoint of social relations respective housings and promoting housings for the elderly people more desirably.
