The knowledge-based 21st century requires lifelong education for the development of qualification of man's life and self-development. Schools are considered a place of lifelong education due to easy access to human resources as well as facilities. Furthermore, schools need a more multi-functional openness in order to lead lifelong education of the local society. Jeju schools are in the early stages of creating multi-functional facilities to meet to the needs of the knowledge-based 21st century. In order to bring change into the local school s, this needs to be solved. therefore, the purpose of this research is to complement the elements to needed to open schools, project, management, and operation of multi-functional facilities, so that schools can play a role In lifelong education. To achieve this purpose, this research examined programs and the area of lifelong education at schools through investigating documents on the definition of local society and lifelong education, and analyzed the relationship of schools and local society, and public access of schools' facilities. The results of this study are summarized as follows; 1) Comparing to traditional middle and high school facilities, it occurs various types of plane and the area is somewhat expanded in the school with same class size, however, it needs to improve facility standards in its reality to deal with the change of future educational environment actively. 2) Spatial composition of educational facilities should functionally designed considering that the characteristics of design process mood. In facilities arrangement of middle and high schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. Therefore, it requires an expansion of space size and facilities for the change of school life outside class.

The purpose of this study is to find out distributional principles of the shop-houses in residential district through physical composition of residential area. Through the research that are based on literature and field survey, it analysed the relation between physical composition of residential area and the shop-houses of selected four sites under similar urban condition where land readjustment project were held. The consequences of this study are summarized as follows; 1) A road that is not penetrating the inside a residential area is seemed to have low occupancy of shops comparing to other roads with similar hierarchy. And the shops functions as convenience facilities. It can be inferred from the statement above that even a road with higher hierarchy is not easy to form commercial area if without penetrating the residential area. 2) According to the size and the arranged method of Inner blocks of residential area towards major roads, distribution of shop-houses appear to be different. In other words, when shop-houses are located along the roads, the proportion of shop was higher than when located perpendicular to the roads. 3) When the number of average lots are little and the size of block is small, usually, street ratio and the number of corners gets higher, which eventually increases the number of shop-houses.

In this paper, a predictive method accounting for the scaling effects of rockfill materials in the numerical deformation analysis of rockfill dams is developed. It aims to take into consideration the differences of engineering properties of rockfill materials between in situ and laboratory conditions in the deformation analysis. The developed method is based on the modification of model parameters used in the chosen material model, which is, in this study, an elasto-plastic model with double yield surfaces, i.e., the modified Hardening Soil model. Datasets of experimental tests are collected from previous studies, and a new dataset of the Nam Ngum 2 dam project for investigating the scaling effects of rockfill materials, including particle size, particle gradation and density, is obtained. To quantitatively consider the influence of particle gradation, the coarse-to-fine content (C/F) concept is proposed in this study. The simple relations between the model parameters and particle size, C/F and density are formulated, which enable us to predict the mechanical properties of prototype materials from laboratory tests. Subsequently, a 3D finite element analysis of the Nam Ngum 2 concrete face slab rockfill dam at the end of the construction stage is carried out using two sets of model parameters (1) based on the laboratory tests and (2) in accordance with the proposed method. Comparisons of the computed results with dam monitoring data indicate that the proposed method can provide a simple but effective framework to take account of the scaling effect in dam deformation analysis.

Forty alcohol yeast strains were isolated from the main mashes (10 strains from each mash) for brewing of 4 different kinds of Korean traditional liquor (3 different types of Yakju and 1 Takju). Thirty-eight out of 40 strains were identified to be the same strain, Saccharomyces boulardii, by the Automated Bacteria, Yeast, and Fungi Identification System (Biolog Co., U.S.A.) based on the metabolic fingerprints. One strain that showed the highest ethanol production among the 38 strains in YPD medium, designated SHY 111, was selected and used for differentiating from other yeast type strains using the polymerase chain reaction (PCR). Amplified DNA, from transcribed internal spacers of SHY 111 chromosomal DNA, was found to be the same in both size and sequence as those of S. cerevisiae KCCM 11215 (formerly S. coreanus) and S. boulardii along with that of S. cerevisiae AB 972, which was used as a type strain for the yeast genome project. However, when PCR was carried out with the intron splice site primer, it resulted in the amplification of the SHY 111-specific DNA fragment which was about 200 bp in size. When PCR was carried out using the primer to test diversity of 40 isolated yeast strains, it was found that the PCR patterns were similar to each other except for the 200 bp bands derived from all the 10 strains from one Yakju, and 2 strains from another Yakju. These results suggest the strain identified as S. boulardii by the Automated Identification System to be a dominant strain for the fermentation of Korean traditional liquors.

본 논문은 기능점수 소프트웨어 규모에 기반하여 개발노력과 일정과의 관계를 유도하는 소프트웨어 공식을 제안하였다. 기존의 소프트웨어 공식은 라인수에 기반을 두고 있다. 라인수는 개발언어에 따라 큰 차이를 보여 소프트웨어 규모 추정에 어려움이 많이 지적되고 있다. 먼저 라인수를 기능점수로 변환하는 방법을 고려하였다. 그러나 이 방법은 개발언어별로 라인수와 기능점수간 변환비율이 명확히 결정되지 않고 있고, 또한 특정 개발언어에 대해서는 변환비율이 제시되어 있지 않아 소프트웨어 공식을 유도하는데 실패하였다. 따라서 기능점수에 기반하여 개발된 대용량의 프로젝트 데이터를 대상으로 소프트웨어 공식을 직접 유도하였다. 첫 번째로 개발 프로젝트들 중에서 타당한 개발기간이 설정된 데이터들을 분류하였다. 두 번째로, 이 데이터에 대해 회귀분석을 통해 기능점수와 개발노력, 기능점수와 개발기간과의 관계를 유도하였다. 마지막으로 이들 관계로부터 소프트웨어 공식을 유도하였다. 제안된 모델은 라인수 기반의 모델이 갖고 있는 적용상 문제점들을 해결하여 실무에 쉽게 적용이 가능한 장점을 갖고 있다.

This research, which is designed to introduce the concept of the WHO's health promoting hospital project to Korea, was conducted in a total of 34 local hospitals across the nation. To evaluate the level of health promotion at hospitals, an evaluation index for health promoting hospital environments was made using the Analytic Hierarchy Process Decision-Making Method, from which a total of 20 questions were developed in the five areas of no-smoking, moderation in drink, exercise, nutrition and rest in Korea. Through this analysis, it was found that local hospitals across the nation were on average excellent in terms of their no-smoking environments, but poor in their rest and moderation in drink environments. A comparison of local public hospital environments by region showed that Busan, Daegu, and South Gyeongsang Province were good, while South Chungcheng Province, Jeju Province and Gwangwon Province were poor. In terms of the number of beds, mid-size local hospitals (200-299 beds) came first. This research revealed that local hospitals across the nation had different health promotion environments according to area and size, and in particular, their environments for rest and moderation in drink turned out to be lacking, which vividly showed that these areas desperately needed to be supplemented in order to introduce the concept of health promotion at hospitals in Korea.

This study was conducted to calculate the LCC of a apartment complex with a type of heating system, district heating and cogeneration system. For the purpose of analyzing LCC according to size of apartment complex, 500, 1,500 and 4,000 houses of model apartment selected. This research performs design of heating system and the life cycle cost analysis including an initial cost, energy cost, maintenance and operation cost, replacement cost and renovation cost during the project period(15years). According to the calculated results, 1) Initial cost of cogeneration system with 500, 1500 and 4000 houses is higher than district heating system each of 20%, 13%, 12%. 2) In case of cogeneration system, the payback period by electric generation is 5.21, 4.92 and 4.47 years and saving cost was calculated 29 billion won, 94 billion won and 262 billion won after payback period. 3) Cogeneration system LCC was 1.12, 1.07 and 1.06 times larger than district system with the size of apartment complex. According to the case of this study district heating system is more efficient than cogeneration system in terms of the reduction of LCC. 4) Gas Engine Co-generation System is more efficient than other systems because it can collect progressive part from electric charge progressive stage system. However, the efficiency is decreasing because of raising of fuel bills(LNG) and lowering of power rate for house use. Especially the engine is foreign-made so the cost of maintenance and repair is high and the technical expert is short. 5) District heating is also affected by fuel bills so we should improve energy efficiency through recovering of waste heat(incineration heat, etc.). Also, we should supply district cooling on the pattern of heat using of let the temperature high in winter and low in summer.
