Recently, many organizations are actively adopting Enterprise Architecture (EA) as a methodology to manage IT assets and build IT-based business system. However, most existing studies on EA have focused on the adoption stage of EA. Now the research concerning effective management and utilization of EA after adopting EA is keenly required. This study intended to empirically examine how the role of EA operating unit and the EA utilization capability of organizational members impact on EA performance at the post-adoption stage of EA. Based on Resource Based View (RBV), this study proposed the model and the hypotheses describing that the impact of the role of EA operating unit on EA performance is mediated by the EA utilization capability of organizational members. In order to test the hypotheses, the field survey whose respondents were seventy four Korean public agencies which have adopted EA was conducted by means of questionnaire. Data analysis was done with partial least square (PLS), which is a structural equation modeling (SEM) technique that uses a component-based approach to estimation. The results of the empirical analyses showed that the organizational operation ability of EA operating unit significantly influenced EA performance via the EA utilization capability of organizational members, but that EA education and training performed by EA operating unit did not. The results of this study provided a lot of theoretical and practical implications regarding EA management activities at the post-adoption stage of EA to enhance EA performance.

실시간 스케줄링 알고리즘에서는 비율단조(RM) 스케줄링 알고리즘과 마감시한(EDF) 스케줄링 알고리즘이 가장 일반적으로 사용되고 있다. 이러한 알고리즘에서는 태스크 집합의 전체 이용율 값을 가지고 수행 가능성을 판별하였다. 그러나 임의의 태스크에서 이용율 값이 초과되면 개별 태스크의 한계성을 전혀 예측할 수 없는 문제점이 있었다. 본 논문에서 제안한 알고리즘은 이용율 값이 초과한 태스크를 예측하고, 개별 태스크의 이용율 값을 기반으로 스케줄링 가능성 여부를 판단하는 방법을 제시하였다. 또한, 실시간 시스템에서 스케줄링 가능성 검사의 한계성을 시뮬레이션을 통해 예측하고 결과를 분석하였다.

Objectives : Recently, the number of elderly people has been rapidly increasing in Korea, and it led to increase demands of Korean traditional medical services. However, there is a lack of information on Korean traditional service utilization. Thus, this study was intended to identify Korean traditional service utilization patterns such as acupuncture, moxibustion and cupping, since Korean traditional services were specially used in treating chronic diseases for elderly people. It is important to understand health services utilization for quality improvement of healthcare systems. Methods:We used data of 'Survey in Daegu' in 2008 and analyzed characteristics of disease structure and utilization patterns of health care service of 1,097 cases of participated citizens. Results : The proportion of the elderly people (>50 age) in total participators is 52.4%. Male to female ratio is 1:1.65 and most common age group was between 50 and 59 years old. 84.2% of participators were admitted at oriental health care facilities. In addition, the results showed that female were more used the service than man. The most common treated disease is musculoskeletal disorders in both male and female. Conclusions : Acupuncture, moxa and cupping are widely used to treat chronic degenerative diseases such as musculoskeletal disorders at oriental health care facilities. Elders and female prefer to be admitted at oriental health care facilities.

Objectives: While the risk of depression is expected to substantially increase among older adults receiving community care, leisure life satisfaction can be regarded as a key component in enhancing the mental health of those receiving community care. However, it is not yet known whether community care utilization increases the risk of depression, or what role is played by leisure life satisfaction in these settings. This study investigated the relationship between community care utilization and depression, as well as the main effect and the moderating role of leisure life satisfaction on the link between community care utilization and depression among older adults. Methods: This study, using the 2019 Korean Welfare Panel Survey, conducted multiple regression analysis on data from 4494 elderly people aged 65 years or older. Results: After controlling for potential covariates, older community care recipients were more likely to report symptoms of depression than those who did not receive community care. Meanwhile, leisure life satisfaction was negatively associated with depression in older adults. The test for interaction between community care utilization and leisure life satisfaction revealed that leisure life satisfaction significantly attenuated the link between depression and community care utilization. Conclusions: The findings of this study imply that leisure life satisfaction could play a meaningful role in improving the mental health of older adults receiving community care. Welfare policies affecting older adults should consider leisure life satisfaction as an important resource for reducing depression in community care settings.

This experiment was canied out to select the optimum utilization method by various pasture types at National Livestock Research Institute, Suwon in 1992 and 1993. Tne main plot was two pasture types. wfiich were mainly top-grass(orchardgrass dominated pasture) and mainly bottom-grass(perennial ryegrass dominated pasture), and the subplot was three pasture utilization methods (grazing, grazing after the 1st cutting, and alternate utilization of cutting and grazing). Average dry matter yields of pasture were not affected by pasture types, but there was significant difference(p <0.05) by pasture utilization methods. Daily DM production of pasture was increased with alternate utilization of cutting and grazing at two pasture types. Also, pasture availability is increased by mainly top grasses and alternate utilization of cutting and grazing. Soil phsical chracteristics are improved by alternate utilization of cutting and grazing. According to the results obtained from this experiment, it is suggested that alternate utilization of cutting and grazing is effective for dry matter yield, pasture availability and soil phsical characteristics regardless of pasture types in Korea.

본 논문은 UNIX 시스템의 최적 이용률(Optimal Utilization)을 결정하는 방법을 제시한다. 제시된 방법은 사용자가 인내할 수 있는 응답시간(Tolerable Response Time)을 제공하는 범위에서 사용자에게 허용될 수 있는 최대 이용률이 최적 이용률이 된다는 정의(Definition)를 근거로 하여 개발되었다. 인내할 수 있는 응답시간이 길어지면 최적 이용률도 높아지므로 최적 이용률은 인내할 수 있는 응답시간의 최대값에서 구해진다. 인내할 수 있는 응답시간은 서비스 목표(Service Objective)가 주어지면 도출해 낼 수 있다. 본 논문에서는 인내할 수 있는 응답시간이 0.24초라는 것과 최적 이용률의 세 가지 구성요소는 %wio, %sys, %usr 이라는 것을 보여준다. 또한 최적 이용률을 결정하는 실제의 과정을 예시하기 위하여 UNIX 운영체제를 사용하는 IBM 컴퓨터의 최적 이용률을 구하는 과정을 예시한다.

The study aims at suggesting the direction of industrial utilization for harmful jellyfish which appears in large quantities in the Korean coastal areas. If the technology of industrial utilization for the jellyfish is developed, it will be possible to grow the industry to the export industry due to the mass appearance of jellyfish in Korean coastal areas. The industrial utilization of jellyfish should follow the direction of minimizing the damage by the jellyfish blooms and maximizing the resource recycling of the jellyfish. Therefore, Korea needs construction of infrastructure for the industrialization and promotion of R&D in order to activate the industrial utilization. Finally, the study suggested issues and tasks for promoting the industrial utilization of jellyfish as follows. First, Korea should stabilize the high quality raw material supply system. Second, mass processing technology should be developed for the industrial utilization of the jellyfish. Third, research and manual development should follow for the preparation of turning the jellyfish to the food. Fourth, extraction technology of useful non-food substance such as extracting collagen from jellyfish should be developed and accelerate the industrial utilization of non-food area.

전자상거래가 경제활동의 새로운 장으로 부각됨에 따라 이의 활용이 기업의 중요한 현안으로 등장하였다. 이에 따라 본 연구는 취약한 국내 중소기업의 전자상거래 활성화 방안 마련을 목적으로 현재 중소기업의 정보화 수준, e-비즈니스 활용 실태를 조사하였다. 조사결과 국내 중소기업의 PC, 인터넷 보급 등 기본적인 인프라는 만족한 수준이지만, 이들은 주로 사무자동화와 같은 기초적인 정보화 활용 수준에 그치고 있었다. 전자상거래 시스템 도입 등 본격적인 정보시스템 활용이 부진한 이유로는 중소기업의 정보화 인력, 기술, 자금 부족이 가장 큰 문제로 지적되었다. 이러한 상황을 고려할때 패키지 소프트웨어나 웹 호스팅 서비스의 보급에 의한 정보화 지원이 가장 적절할 것으로 판단되며, 정책적인 차원에서의 웹 기반 ASP(Application Service Provider)의 개발 및 보급과 자금지원, 교육, 자문을 구체적 방안으로 제시하였다. 또한 정보화 투자대비 효익에 대한 기업의 우려에 대해 우수사례 발굴과 홍보, BSC(Balanced Scorecard)를 통한 경영성과 측정지표의 개발이 필요하며, 이를 기반으로 효율성이 높은 분야에 대한 집중적 지원이 요구된다.
