  • Gyeonggi Province is trying to increase the number of public libraries from 100 as of December, 2006 to 150 in 2010. However most of existing public libraries preferred mid-to-large scale libraries, so they were restricted to be located in around a zone of life. For this reason most local residents have been excluded from right to use libraries and have difficulties to get library services for the knowledge and information society of the 21st century. The alternative to the small library is a school library. Both schools and public libraries are located in around a zone of life because residents can get an access to them easily. First, considering that small-scale public libraries of communities usually service about 10,000-20,000 people, I estimate that an open-style school library services 24class, 840people (24class*35people) of elementary school by 2003 Korean Library Standard (edited by Korean Library Association). Second, it requires systematic protection policies so that the open-style school of library can function as a local public library and a part of library cooperation system in accordance with local plans. All the open-style school libraries don't intend to open and we had better consider the suitable service areas. Third, it's desired for the management efficiency that the open-style school libraries being established afterward are divided into a branch-scale, a hall-scale and so on, not being uniform management model. And it also needs that one of them in the area enlarges the scale, and then supports other school libraries. According to these results of the research, as cooperation between the public library policy of a local government and school library policy, it needs a systematic support.

  • In recent years, concerns have been growing globally regarding greenhouse gases. Open burning of biomass causes emission of a number of greenhouse and other gases and substances. This paper studied an analysis on the characteristics of four types of biomass using duel type cone calorimeter. Cone calorimeter is widely used for assessing combustibility of materials in Europe. As a result, we evaluated several characteristics of biomass, such as heat released rate, smoke production rate, CO, $CO_2$ production and mass loss rate, and so on. $CO_2$ is currently responsible for over $60\%$ of the enhanced greenhouse effect, and may be the most important contributor to future. $CO_2$ production for biomass in the range of $1.74\~1.99kg/kg$ is similar to previous research conducted by Bhattacharya et al. (2002a).

  • The purpose of this study is to present the direction of the plan to transform the residential complex into a space that can provide an open residential environment that can lead to social communication and exchange without being closed to the urban residential environment, especially in the apartment complex environment, which is becoming more dense. As a result of the Openness analysis of the 'Codan Shinonome Canal Court', the overall accessibility was good in terms of space utilization, and the openness was low in terms of the spatial composition, which is a physical environment due to the dense block type. When looking at the overall openness of the Codan Sinonome complex in terms of analysis by block, the corrected openness index (C.O.I) for all six blocks was 0.245, the corrected accessibility index (C.A.I) was 1.447 and the openness composite index (O.C.I) was assessed at 1.692. This was due to the formation of high-density block-type urban dwellings and the introduction of S-shaped streets and the layout of low-rise urban support facilities and commercial facilities. The Codan Sinonome Canal Court, which is considered an "open city residence," quantitatively confirmed that it embodies macro-space structure and human-scale space environment even in high-precision environments.

  • 대기오염에 관한 연구가 진행되면서 광화학반응의 기여도가 높고, 인체에 직,간접으로 영향을 미치는 VOC를 포함한 비기준성 대기오염물질을 실시간으로 측정 할 수 있는 방법에 대한 필요성이 크게 증대하고 있다. Open-path 광학기기는 가스크로마토그래피 등 종래 sampling 방법과는 달리, 대상지역내 대기오염물질을 별도의 채취없이 실시간으로 측정함으로써, 대기오염물질 채취에서 야기되는 오차를 제거하고 여러화학종의 동적 변화에 관한 자료를 제공함으로써 대기오염물질 거동에 중요한 자료를 제공하고 있다. (중략)

  • DOAS (Differential Optical Absorption Spectroscopy) System은 대기 중에 존재하는 기준물질들이 특정 파장영역에서 빛을 흡수하는 원리를 이용하고 있다. 현재 독일을 중심으로 한 유럽과 선진국에서는 대기 환경 기준물질의 모니터링 기술들이 주로 광 투과방식을 이용한 Open path의 모니터링 기술들을 개발하고 있다. 기존의 측정 방법과 Open Path 모니터링의 기법을 비교 할 때 Open path 시스템은 실시간 측정 및 분석이 가능하므로 기존의 화학적 측정방법에서 제기되어져왔던 화학 반응시의 방해 물질의 간섭제거 및 시간 분해도 향상등에 큰 장점이 있다.

  • This study investigated the difference of perception and needs among director, teacher, and parent for an open-childcare center focused on parent participation. The subjects of this study consisted of 56 directors, 231 teachers, and 299 parents in childcare centers in Seoul, Gyeonggi, Incheon, Chungcheong, and Gyeongsang province. They completed a questionnaire about the perception and needs of an open-childcare center, which was later analyzed by SPSS ver. 23.0. The findings were as follows. First, five areas of open-childcare center were 'participating activities as various roles,' 'willingness of parent participation,' 'reflection of parent needs,' 'concern about CCTV,' and 'sharing outdoor spaces.' Second, the perception of directors concerning open-childcare centers were higher than the ones for teachers or parents; however, there were differences in perception depending on their perspective position. The biggest perception of directors was 'participating activities as various roles,' and parents' one was 'concerned about CCTV.' However, the perceptions of teachers were a lower level than the other two groups'. Third, the directors showed a higher level of needs to promote an open-childcare center (except for one concerned about CCTV). Parents also showed their needs 'increasing awareness of open-childcare program,' 'promoting to parent's participation,' 'communication with on-line,' and 'concerning CCTV.' The implication of these results were discussed as action plans to promote an open-childcare center.

  • In order to address housing issues, alleviate the concentration of urban populations, and resolve other issues regarding residential spaces, large residential complexes have been developed in Korea since the 1970s. The changes to the residential culture due to such development projects propagated rapidly, making the apartment complexes the most representative form of housing in Korea. In developing such large-scale complexes, plans for public open spaces, which play an important role in formulating the quality of residential environment, have been mostly the same, only utilizing the spaces remaining after planning other types of spaces. The current study looks at the case of Tama New Town development project, a Japanese new town development project that has a similar public open space system in large scale residential complex development projects in Korea. In doing so, the current study aims to identify the features of public open space plans. In the conclusion, the study first finds that various public open spaces must be reviewed and introduced in term of predicting social demands. Second, the study suggests the policy-makers should actively introduce pedestrian paths as a public open space. Third, the study deduces the planning implications of applying the principle of original landscape preservation.
