It is a world wide tread for museums to become specialized museums emphasizing their characteristics, but Seongbo museums(museums that preserve Buddhist artifacts) are more general and show no specialization or characterization. The purpose of this study is to emphasize the special character of the Seongbo museum which manages and maintains sacred Buddhist cultural artifacts, and to understand the architectural characteristics of the building distribution and interior composition to implement a more systematic spatial composition plan. For our analysis we selected 6 currently operating museums as our subjects, and analyzed the characteristics of their spatial composition through their plans including the plot plans and ground plans. As a result, we found that most of them were small scale museums, and that the character and rank of each building changed according to its positioning. In terms of areas, the museums consisted of exhibition areas, storage areas, maintenance areas, and other miscellaneous areas and were lacking areas for research and education. It is necessary for these museums to possess facilities for managing these cultural artifacts as well as adequate exhibition and storage spaces. Seongbo museums, which are connected with Buddhist temples, must possess differentiated preservation and maintenance methods unlike museums dealing with artifacts that need only be preserved, and must have an area plan suitable to the characteristics of the various artifacts near and around the temple so as to help build our Buddhist cultural heritage in a systematic and continuous matter.

This study aims to make a revitalizing plan for managing and maintaining of facilities which were installed after the rural development projects. The survey was conducted to examine some issues of operating facilities from the developing plan. There were some factors that should be considered in the establishment stage of the project plan when promoting rural development projects. Among them, the preservation and maintenance of rurality, consistency with business plans, connectivity with local resources, and ease of maintenance were less reflective than its importance. And for each facility, systematic consulting on appropriate scale and operational management plans and detailed planning is needed.. It's also necessary to plan action so that the local community can lead. The current or future rural development project will be succeeded when local governments support to strengthening their local groups or people's abilities.

식품의 신선도를 유지하기 위한 효과적인 식품 포장 물질로서 항균성질을 갖는 신선도 유지 성분인 겨자 유를 적용한 다공성 필름의 성능과 효능을 알아보기 위하여 GC-MSD 분석과 식빵에 대한 곰팡이 실험을 하였다. 겨자유에서 얻을 수 있는 AITC와 같은 물질은 기체상 접촉을 통한 적용법이 항곰팡이성 효과가 크게 나타나므로 GC-MSD 분석을 통해 겨자 유를 함유한 포장 소재에서의 항곰팡이 효과와 식품의 저장기간의 효과를 최대화 할 수 있는 조건을 찾고자 하였다. 필름 크기와 포장 조건을 찾기 위해 4가지 다른 조건으로 실험하여 당일과2일 후의 AITC을 측정하였다. 그 결과 항균층 폭이 25 mm, 길이 20 cm인 필름 2개를 사용했을 때가 항균층 50 mm 필름 1개를 사용했을 때 보다 밀폐된 포장 용기에 AITC가 더 많이 보유되어 있음을 알 수 있었다. 이 결과는 필름제조 시 안쪽 필름의 $20\;{\mu}m$의 기공 쪽보다 옆 단면 층과 층사이의 기체 확산이 더 크게 일어난다는 것을 보여주었다. 식빵 저장 실험에서 곰팡이 유무를 확인한 결과 작은 사이즈 2개를 넣었을 때가 저장 일이 25일로 가장 길게 나타났다. 또한 필름에 남아있는 AITC 양을 측정하기 위하여 크기가 다른 밀폐 용기에서 실험한 결과 부피가 43 mL 공간에서 많이 측정되었고 반면 500 mL, 1000 mL는 공간이 다름에도 불구하고 AITC는 그다지 차이가 없게 나타났다. 오픈한 상태에서 당일 1일, 2일, 4일 후에 AITC량을 측정한 결과 초기에 급격하게 기체가 배출되어 4일 후에는 거의 남아있지 않았고 특히 국산제품이 수입품보다 더 빨리 기체가 배출됨을 나타내었다. 신선도 유지성분인 겨자유의 방출 특성과 조건을 분석함으로써 항곰팡이성 효과를 극대화 할 수 있는 필름조건을 조사하여 식품에 대한 적용 확대가 기대 된다.

현대의 경찰 활동은 경찰공무원 개인에 의한 독자적인 수행보다는 조직구성원의 상호 작용을 통해서 이루어지고 있다. 국민의 생명과 신체 및 재산을 보호하고 사회 질서를 유지하기 위한 경찰 조직의 목표 달성에 있어서 적합한 경찰공무원의 선발 및 입직 후 경찰공무원의 자질 향상과 역량 강화는 중요한 요소이다. 하지만 경찰 조직은 팀별 활동에 기반을 두고 있는 특성을 갖고 있기에 조직 특성에 적합하게 활동하고 사회질서 유지를 위해서는 무엇보다 경찰공무원들의 상호 협력이 더욱 중시되고 있다. 따라서 본 연구는 초동적인 경찰 업무 활동을 하고 있는 외근 경찰공무원으로 국한하여 이들의 사회질서 유지를 위한 조직효과성에 대한 인식 차이를 살펴보았다. 실증 분석 결과, 외근 경찰공무원의 인구사회학적 특성에 대한 개인별 변수 중에서 성별, 연령, 근무지역, 경찰서 급지, 계급, 근무기간에 따라 조직효과성 인식은 통계적으로 유의미한 차이가 있는 것으로 조사되었다. 그러나 경찰공무원의 학력과 결혼여부에 따른 조직효과성의 인식은 차이가 없는 것으로 파악되었다. 이를 통해 경찰공무원의 조직효과성을 향상 시킬 수 있는 방안이 시급히 마련되어야 할 것이고 획일적인 운영과 관리에서 탈피하여 성별, 연령별, 지역별, 경찰서 급지별, 계급별, 근무기간에 따라 세분화하여 차별화된 교육 훈련이 필요하다고 본다. 내부 구성원의 조직효과성을 향상시키고 나아가 외부 고객인 국민의 만족을 유발하여 궁극적으로 사회질서 유지에 이바지할 수 있을 것이다.

Industrial facilities are becoming more complex and various with rapidly developing technologies. A number of installations and equipments are increased to improve productivity, and they are operated under the condition of high temperature and pressure. They are continuously repaired, replaced or abolished because of the deterioration with time, but their repair and replacement are not easy for economical and environmental concerns. If possible, the deteriorating equipments should be inspected and repaired effectively considering the state of maintenance and preservation, economic efficiency, and safety. That's where RBI(Risk Based Inspection) fits in. Even if RBI technology has been known among specialists, there were no tools readily available and it was hard to practice and apply RBI in industrial inspection and safety management. In the development of the qualitative RBI, the overall algorithm adopted API-581 BRD. The qualitative RBI program was developed to search the appling process.

Environmental conservation is becoming the major conversation topic in the 21st century, the era of environment. In the Law for the Preservation of Water Quality, article 53 states "A business unit which is doing business causing pollution caused by non-point pollutant or builds waste water discharge facilities, should report the installation of the non-point pollutant and install the required pollution control facilities". Environmental pollution caused by oil leaks during operation or maintenance has been found in the railway sector. Especially, rolling stock depot is most likely to be affected by environmental pollution. Therefore, in this paper We have investigated non-point pollutant in the rolling stock depot area and have studied adequate disposal method to minimize the effect of the non-point pollutant, hoping to supply the preliminary data for building an environment-friendly rolling stock depot.

The Act on Safety Management of Social Assets was established on 1995 and revised on 1999 to relieve maintenance cost of managing offices. The provision for load bearing test before opening was deleted and the number of load bearing test after opening was reduced in the Revised Act on 1999. The effect of revision is the main concern in this study. 176 technical reports on load bearing test of long span bridges are analyzed. The results show that various structural defects are inherent in recent bridges constructed since 1995. So the preservation of provisions deleted in original act is needed up to now.

The ovarian follicles develop initially from primordial follicles. The majority of ovarian primordial follicles are maintained quiescently as a reserve for the reproductive life span. Only a few of them are activated and develop to an advanced follicular stage. The maintenance of dormancy and activation of primordial follicles are controlled by coordinated actions of a suppressor/activator with close communications with somatic cells and intra-oocyte signaling pathways. Many growth factors and signaling pathways have been identified and the transforming growth factor-beta superfamily plays important roles in early folliculogenesis. However, the mechanism of maintaining the dormancy and survival of primordial follicles has remained unknown for decades. Recently, since the first finding that all primordial follicles are activated prematurely in mice deficient forkhead box O3a, phosphatidylinositol 3 kinase/phosphatase and tensin homolog (PTEN) signaling pathway was reported to be important in the regulation of dormancy and initial follicular activation. With these informations on early folliculogenesis, clinical application can be expected such as in vitro maturation of immature oocytes or in vitro activation of follicles by PTEN inhibitor in cryopreserved ovarian cortical tissues for fertility preservation.
