Environment is the important issue in many field of study. EU introduced multifunctionality of agriculture in 1980s and adopted strong policy to support that in 1990s. Environment is very important factor of multifunctionality of agriculture. But multifunctionality is not purpose in itself. It is exceptional rule and a means to an purpose. Multifunctionality of agriculture is relation to logic of economics. Mutifunctionality of agriculture was introduced in Korea in 1990s. Owing to different paradigm approach, multifunctionality of agriculture and environmental education have different concept and basis. The purpose of this study is to introduce socio-economical context of multifunctionality of agriculture and enhance mutual understand. More study activities should be encouraged to improve mutual understand and interdisciplinary research.

Heidegger's speculation on "Disclosure" makes it possible to know on image expression fundamentally. "Disclosure" means that the 'earth' and the 'world' are not fixed into one, but harmonize dynamically with each other under continuous mutual tension and mutual support. When they are well-weaved with each other, the two ways are collectively defined as "disclosure Image". In regard to the technique, the study analyzed 'allegory' and 'reactivation'. The former refers to showing image potentially, while the latter means embodying and revealing image apparently. Le Corbusier's late Architecture provides a simultaneous reactivation of various images through continuous cross-weaving rather than being inclined to either the earth or the world.

Seafarers from 21 APEC economies, are not only an indispensable source of human capital for the global maritime industry, covering at least 56% of the world's seafaring population (BIMCO, 2015), but also pivotal in providing support to their economies as a major industrial pillar, specifically in developing economies where the development of skills and enhancement of labor mobility of human resources is essential in creating sustainable and inclusive regional growth. This paper examines challenges and barriers in seafarer mobility in relation to policies in APEC economies and investigates mutual collaborative actions that can be taken to address the issues identified in a coordinated and harmonised manner.

Purpose: The purpose of this study is to confirm the relationship between nursing students' self-determination and life satisfaction in order to clarify the mediating effect of grit and social support, which can have a mutual influence on self-determination and life satisfaction. Methods: The data collection for this study was conducted from January 1 to 31, 2022, with nursing students enrolled in nursing departments at six universities located in three regions. The data collected in this study were analyzed using the IBM SPSS statistics 25.0 program. Results: The study found correlations between life satisfaction and self-determination (r=.64, p<.001), grit (r=.41, p<.001), and social support (r=.46, p<.001). Grit (B=0.06) and social support (B=0.06) showed a mediating effect in the relationship between self-determination and life satisfaction. Conclusion: Based on the results of the study, it is suggested that a program that can enhance the life satisfaction of nursing students be developed and implemented by focusing on social support, which is an external resource, and self-determination and grit, which are internal resources.

Previous research on elderly care in rural areas has focused on inter-generational support, ignoring the possibility of elderly care among community members in the rural areas of Korea. This study attempts to explore the roles and potentials of community-based elderly care in rural areas where nearby family or formal services are unavailable. For this purpose, data was collected from the elderly in three Korean rural villages using qualitative case study methods. Each village was studied as a separate case study and in-depth interviews with the elderly in each village were conducted. All interviews were tape-recorded and transcribed verbatim for the analysis. The data was analyzed using the Reflective Qualitative Analytic Technique. Results showed that rural elderly in all three villages had lunch, talked, and played together; almost everyday in the winter. However, the nature of care among rural elderly varied depending on the characteristics of the rural community (the traditional rural, the rural mixed with the urban, and the neighboring rural with the urban). Specifically, the use of mutual aids (providing food, repairing housing, and checking personal safety by telephone or visit, etc.) was most consistent at the traditional rural village. Because both the rural village mixed with the urban and the neighboring rural village with urban have better access to many aids and programs from formal institutions, mutual aids among community members decreased compared with the traditional rural village. However, regular group activities such as sports, dancing or debate help to provide pleasure and integrate the community. These results suggest that community relationships as a substitution for social support provide by family or formal services can be utilized in rural areas.

이동 호스트란 시간과 공간의 제약 없이 필요한 기능을 수행하고, 또한 원하는 정보에 접근할 수 있는 휴대용 컴퓨터를 일컫는다. 이동 컴퓨팅 환경이란 이러한 이동 호스트들을 지원할 수 있도록 구성된 분산 환경이다. 따라서 이동 컴퓨팅 환경에서의 분산 알고리즘은 정적 호스트만을 고려한 기존의 분산 환경에서와는 다르게 이동 호스트의 여러 가지 특성들을 고려하여 제안되어야 한다. 즉, 이동 컴퓨팅 환경의 도래로 인하여 이동성과 휴대성, 그리고 무선 통신과 같은 특성들을 고려한 새로운 분산 상호 배제 알고리즘이 필요하다. 이제까지 이동 컴퓨팅 환경에서의 상호 배제 알고리즘은 토큰 링 구조에 기반을 두고 설계되었다. 토큰 링 구조는 이동 호스트들의 위치를 유지하기 위하여 높은 비용을 필요로 하는 단점을 가지고 있다. 본 논문에서는 균형 높이 트리(height-balanced tree)라는 새로운 모형을 제안함으로써 정적 분산 환경과 이동 분산 환경이 혼합된 환경에서 상호 배제 비용을 감소시킬 수 있는 새로운 알고리즘을 제안하며, 각 경우에 있어서의 비용을 산출하고 평가한다.Abstract The mobile host is a potable computer that carries out necessary functions and has the ability to access desirable informations without any constraints in time and space. Mobile computing environment is a distributed environment that is organized to support such mobile hosts. In that environment, distributed algorithms of which environment not only with static hosts but with mobile host's several properties should be proposed. With the emergence of mobile computing environments, a new distributed mutual exclusion method should be required to consider properties mobile computing system such as mobility, portability, and wireless communication. Until now, distributed mutual exclusion methods for mobile computing environments are designed based on a token ring structure, which have the drawbacks of requiring high costs in order to locate mobile hosts. In this paper, we propose a distributed mutual exclusion method that can reduce such costs by structuring the entire system as a height-balanced tree for static distributed networks and for networks with mobile hosts. We evaluated the operation costs in each case.

본 연구의 목적은 현대화과정에서 나타나는 노인부양의 변화과정을 농촌노인의 관점에서 재구성하는 데에 있다. 이를 위해 6쌍의 노인부부와 3차례에 걸쳐 Schütze의 '생애사적-이야기식 인터뷰' 17개를 하였고, 분석도 그의 '생애사적-이야기식 인터뷰 분석' 방법에 따라 하였다. 연구결과, 본 '생애사주체들'이 경험한 노인부양은 '가족부양'이 주를 이루는데, 현대화과정을 거치면서 '이중적으로 구조전환'된 것으로 나타났다. 즉 한편으로는 '세대 간 상호부양 차원의 가족부양'이 '세대 내 자기부양 차원의 가족부양'으로 변환되는 '내적 구조전환'이, 다른 한편으로는 '가족부양의 사회화'가 이루어지는 '외적 구조전환'이 나타났다는 것이다. 또한 이러한 '이중적 구조전환' 과정에서 나타난 부양규범과 부양행위는 '괴리'를 이루고 있는 것으로 나타났으며, '이중적 구조전환'에 대한 인식은 '양가적'으로 나타나고 있음을 분석하였다. 이러한 연구결과에 근거하여 현대화이론에 대한 비판적 논의를 하였고, 노인부양을 위한 실천적 함의도 제시하였다.
