분산 시스템에서 글로벌 스케쥴러를 위한 Meta_Level Control 설계 및 성능 평가
강봉한(BongHan Kang),안정원(JeongWan Ahn),김영찬(YoungChan Kim) 한국정보과학회 1990 한국정보과학회 학술발표논문집 Vol.17 No.2
분산 시스템에서는 시스템의 상태와 task의 특성이 동적으로 변화하므로, 하나의 스케쥴링 기법으로 모든 상황에서 최적으로 작동하기는 힘들다. 그러므로 노드와 통신 네트워크의 상태, task의 특성 등에 따라 좋은 효율을 얻기 위하여 스케쥴링 기법과 parameter를 조정하는것을 meta-level control이라 한다. 본 논문에서는 글로벌 상태 정보를 얻기 위한 통신 비용의 감소를 목적으로 하는 계산주도형 기법(베이지안 이론)을 이용한 부하균등화를 모델을 기반으로 노드의 상태에 따라 상태 정보 갱신 주기를 유동적으로 변화시켜 상태 정보 획득 횟수를 줄이고도 성능을 향상시킬수 있도록 설계하였고, 각 node의 상태가 급변할 때 통신주도형 방식인 입찰(bidder)방식을 이용하여 정확한 결론을 얻을 수 있도록 하여, 고려된 모든 상황에서 near-optimal한 결과와 안정된 상태를 유지할 수 있도록 설계하였다.

본 연구는 태양광 발전사업의 확산과 무분별한 입지에 따른 농어촌 지역 경관관리와 신재생에너지 산업의 균형적 발전 방법을 모색하기 위한 것이다. 이를 위해 약 60여 개의 섬과 다양한 해안선을 함께 보유하고 있는 전라남도 해남군을 대상으로 최근 3년간의 농어촌 태양광 발전시설 인·허가 현황을 전수조사하여 설치 특성을 파악하고 전라남도 22개 시·군 전체를 대상으로 태양광 발전시설의 무분별한 확산을 방지하기 위한 유도·규제 현황을 분석하였는데 구체적인 연구 결과는 다음과 같다. 조사대상 지역인 전라남도 해남군은 도내 타 시·군에 비하여 연중 일조량이 풍부하고 해안에 면하는 지역이 넓어 태양광 발전사업에 비교적 용이한 것에 영향받아 최근 3년간 농어촌태양광 발전시설 허가건수가 총 2,357건에 달하는 등 지속적인 증가 추세를 보였다. 그러나 농어촌 태양광 발전시설 설치가 이루어지는 부지의 지목이 대부분 전(밭)과 답(논)이라는 점과 우수 문화 및 해안경관으로서의 가치성이 인정되는 염전이 상당 부분 태양광 발전사업 부지로 편입되는 경향을 보이고 있다는 점 그리고 용도지역상 생산관리지역과 농림지역에 집중하여 이루어지고 있다는 점, 농어촌 태양광 발전시설 사업주체(사업자)의 대부분이 외지인(87.6%)으로서 농어촌 태양광 발전사업의 취지에 어긋나고 있다는 점 등의 문제가 있음을 것을 확인할 수 있었다. 반면 농어촌 태양광의 무분별한 확산을 막고 적성성 유지를 위한 유도·규제 방법으로 전라남도 22개 시·군 모두에서 자치단체 조례 등을 통해 태양광 발전시설 사업과 관련된 제한 사항을 마련하여 운용하고 있는 것으로 나타났는데, 내용적으로 태양광 발전시설의 규모나 형태 등에 대한 구체적인 사항보다는 국도·군도 등 도로나 주거지, 관광지·공공시설 그리고 문화재 등 특정 시설로부터의 이격거리 제한이 주를 이루는 것으로 나타났다. The purpose of this study is to minimize the impact on the rural landscape due to the spread of solar power plant businesses and reckless location choices, and to seek a balanced development method of the renewable energy industry. To this end, the characteristics of Haenam-gun, Jeollanam-do, which has about 60 islands and various coastline types, was investigated for three recent years of planning permission for solar power plant facilities in rural areas. In addition, the status of induction and regulation to prevent the indiscriminate spread of solar power plants in 22 cities and counties in Jeollanam-do was analyzed. The detailed research results are as follows. Haenam-gun has abundant sunshine throughout the year and has a wide area facing the coast, compared to other cities and counties, Therefore, it is relatively easy for solar power plant business. Because of this the number of permits for solar power plant facilities in rural areas reached 2,357 in the past three years, and there was a continuous increase every year. Moreover, most of the sites where solar power plant facilities were installed were in rural areas such as on fields or rice paddies, and there were many located on salt fields that are recognized for their excellent culture and value as a coastal landscape. By using the City Planning Area, there were many PMA(Production Management Areas) and AFA(Agricultural and Forest Areas). Therefore, it was confirmed that there is a problem regarding the loss of agricultural land and salt fields and that there is a problem that most of the business operators are outsiders (87.6%), which is contrary to the purpose of the solar power plant business. On the other hand, it was found that all 22 cities and counties in Jeollanam-do established and operated restrictions related to solar power plant facility businesses through the ordinances of each local government as a method of induction and regulation to prevent the indiscriminate spread of solar power plants in rural areas. In terms of this, it was found that the limitation of the distance from specific facilities such as roads, residential areas, and cultural properties was focused on rather than matters about the size or shape of the plants. Therefore, it is considered that there is a need for a comprehensive approach to conduct further research on the induction and regulations related to the establishment of solar power plant facilities in rural areas.

The purpose of this study was to analyze the relationship of the floor classification and the main-living behavior, and the tendency of using furniture and space by surveying the situations of using An-bang space by apartment dwellers. An-bang is a factor that influences on the unit-plan organization, the whole spatial arrangements, and the spatial relation and size, and has the most severe friction between the tradition and western culture. Given seeing the results shown in the main-living behavior by floor type, that the rest and TV watching were shown to be high in terms of a free-standing type can be said that An-bang is more for the individual rest than far the purpose of family harmony. On the other hand, that the family courtesy was shown to be a little higher a sitting-down type, could be understood that the sitting-down style, which is a traditional living mode, is appearing in An-bang.

The purpose of this study is to deduce dwelling selection criterion and to consider change of values and consciousness of dwelling on people who return to farming & going to village. For that, questionnaire of evaluation of housing choice is conducted by people who return to farming & going to village in Jellanam-do by the AHP. The results are as follows. First, four factors as the primary hierarchy structure and 12 factors as the secondary hierarchy structure of dwelling selection criterion are deduced. The primary hierarchy are "education environment", "economic & Convenience in life", "residence safety and image", and "economic value". Second, weight value deduced from the primary hierarchy structure is showed that "economic & convenience in life(0.345)" is the highest and next is "education environment(0.262)". "Residence safety and image(0.237)", and e "economic value(0.157)" is relatively low(C.I. 0.213). Third, for the secondary hierarchy structure, the case of life convenience is showed that economic condition(0.403) is the highest, the case of educational condition is showed that education facilities(0.479), the case of residence safety and image is showed that residence area(0.490) is the highest, and the case of economic importance is showed that financial technology(0.470) is the highest.

This research is studied changes of outdoor lavatories in use of detached houses in rural areas. Out of 40 houses studied in a 1995 survey, 23 houses were performed again in 2015. Number of lavatories installed in indoor and outdoor both in 1995 are more than in 2015. However, number of indoor lavatories in 2015 are more because outdoor lavatories were demolished. Among 23 houses, 15 outdoor lavatories have been installed in 13 houses. Out of these 15 lavatories, eight have been used continuously from 1995 through 2015. Currently four are used for other purposes, and five have demolished. Outdoor lavatories tend to be built in the rear of the housing site. Those located in rear tend to be demolished rather than in front side because of decreasing in use. In rural areas, outdoor lavatories not only serve as spaces to fulfill basic human needs, but are used to store agricultural tools. Changes of family composition and member also exert an influence. When family members were decreased, outdoor lavatories tended to be demolished. However, although family members were decreased, the reason that outdoor lavatories have been used continually is for exterior work or farming and temporarily increasing family members in holiday and family events. The more family members used, the more outdoor lavatories are managed well. The more houses where the aged reside in, the more outdoor lavatories are not improved.
