In design of a deep geological repository for the high level wastes, it is very important that the temperature of the bentonite block should not be over $100^{\circ}C$ to maintain the integrity of the bentonite buffer block from the decay heat. In this study, for the layout of the repository to meet the requirement, the analysis of the disposal tunnel and disposal pit spacing was carried out. To do this, based on the reference repository concept, several cases of cooling times and disposal tunnel and disposal pit spacing were compared. The thermal stabilities of the disposal systems were analyzed in terms of the cooling time and spacing. The results showed that it was more desirable to determine the layout of the repository in terms of disposal pit spacing than the disposal tunnel spacing. The results of these analyses can be used in the deep geological repository design. The detailed analyses with the exact site characteristics data will reduce the uncertainty of the results.

The purpose of the HLW deep geological disposal is to isolate and to delay the radioactive material release to human beings and the environment for a long time so that the toxicity does not affect to the environment. The main requirements for the HLW repository design is to keep the buffer temperature below $100\;^{\circ}C$ in order to maintain its integrity. So the cooling time of spent fuels discharged from the nuclear power plant is the key consideration factors for efficiency and economic feasibility of the repository. The disposal tunnel/disposal hole spacing, the disposal area and thermal capacity required for the deep geological repository layout which satisfies the temperature requirement of the disposal system is analyzed to set the optimized spent fuels cooling time. To do this, based on the reference disposal concept, thermal stability analyses of the disposal system have been performed and the derived results have been compared by setting the spent fuels cooling time and the disposal tunnel/disposal hole spacing in various ways. From these results, desirable spent fuels cooling time in view of disposal area is derived. The results shows that the time reaching the maximum temperature within the design limit of the temperature in the disposal site is likely shortened as the cooling time of spent fuels becomes short. Also it seems that the temperature-rising and-dropping patterns in the disposal site are of smoothly varying form as the cooling time of spent fuels becomes long. In addition, it is revealed that a desirable cooling time of spent fuels is approximately 40-50 years when spent fuels are supposedly disposed in the deep geological disposal site with its structural scale under consideration in this study.

우리나라에서 운영하는 원자력발전소는 PWR형과 CANDU형 2종류가 있으며, 원자력발전에 의한 지속적인 에너지 공급을 위하여 이들로부터 발생하는 사용후핵연료에 대한 안전관리는 매우 중요한 인자이다. 사용후핵연료 처분을 위한 연구는 1997년부터 시작하여 한국형 사용후핵연료 처분시스템을 개발하였으며, 현재는 개발된 기술에 대한 실증 및 처분시스템의 효율향상을 위한 연구를 진행하고 있다. 또한, PWR형 사용후핵 연료의 경우 사용후핵연료 재활용 공정을 거쳐 원료물질로 다시 사용하는 연구가 진행 중이므로, 이들 공정으로부터 발생하는 고준위폐기물을 처분하는 방안을 강구하고 있다. 이에 따라 본 논문에서는 PWR형과 CANDU형 사용후핵연료 모두를 직접 처분하는 개념으로 개발한 한국형 사용후핵연료 처분시스템을 바탕으로 CANDU형 사용후핵연료 처분 시스템의 처분효율을 향상시키는 방안을 도출하고자 하였다. 이를 위하여, 한국형 사용후핵연료 처분시스템의 CANDU 사용후핵연료 처분용기를 개선하여 현재 원자력발전소에서 사용하고 있는 사용후핵연료 60 다발(Bundle) 용량의 저장바스켓을 포장 활용하는 개념을 도출하고, 열해석을 통하여 처분시스템 완충재의 온도가 $100^{\circ}C$를 넘지 않도록 하는 요건을 만족하는 처분터널 및 처분공 간격을 정하여 이들에 대한 처분시스템 개념을 도출하였다. 이렇게 설정된 개념들을 단위면적당 열효율, 우라늄밀도(U-density), 처분면적, 굴착량, 완충재 및 폐쇄 물질량 측면에서 분석하여 처분효율이 가장 높은 방안을 제안하였다. 본 연구의 결과는 추후 실제 부지특성자료와 연계하여 PWR 사용후핵연료 재활용공정으로부터 발생한 고준위폐기물 처분시스템과 함께 복합 처분장 설계에 활용될 것이다. There are two types of nuclear reactors in Korea and they are PWR type and CANDU type. The safe management of the spent fuels from these reactors is very important factor to maintain the sustainable energy supply with nuclear power plant. In Korea, a reference disposal system for the spent fuels has been developed through a study on the direct disposal of the PWR and CANDU spent fuel. Recently, the research on the demonstration and the efficiency analyses of the disposal system has been performed to make the disposal system safer and more economic. PWR spent fuels which include a lot of reusable material can be considered being recycled and a study on the disposal of HLW from this recycling process is being performed. CANDU spent fuels are considered being disposed of directly in deep geological formation, since they have little reusable material. In this study, based on the Korean Reference spent fuel disposal System (KRS) which was to dispose of both PWR type and CANDU type, the more effective CANDU spent fuel disposal systems were developed. To do this, the disposal canister for CANDU spent fuels was modified to hold the storage basket for 60 bundles which is used in nuclear power plant. With these modified disposal canister concepts, the disposal concepts to meet the thermal requirement that the temperature of the buffer materials should not be over $100^{\circ}C$ were developed. These disposal concepts were reviewed and analyzed in terms of disposal effective factors which were thermal effectiveness, U-density, disposal area, excavation volume, material volume etc. and the most effective concept was proposed. The results of this study will be used in the development of various wastes disposal system together with the HLW wastes from the PWR spent fuel recycling process.

In this study, analysis of the disposal tunnel spacing and disposal pit pitch was carried out, as a factor of the design to estimate the scale and layout of the repository. To do this, based on the reference repository concept and the engineered barrier concept, several cross sections of the disposal tunnel and disposal pit were established. After then, the mechanical and thermal stabilities of the established tunnels were analyzed. Also, an optimized disposal tunnel spacing and the disposal pit pitch reducing the excavation volume was proposed. The results of these analyses can be used in the deep geological repository design. The detailed analyses by the exact site characteristics data to reduce the uncertainty of the site and the modification for the optimization are required.

The biggest change for Korea in the 21 st Century has been the advent of multicultural society. There are over a million foreigners living in Korea. Multiculturalism now sounds familiar to Koreans. Thus, Korea is no longer an ethnically homogeneous nation but, rather, a multi-ethnic nation. This study focus on the Chinese brides of Koreans living in Seoul, Gyeonggi Province, and Incheon. The aim of this study is to survey the responsiveness of Korean government when they receive public services. It then determines the differences between groups and analyzes how it changes according to different independent variables. In this study, multicultural Korean government services for foreign brides of Koreans are divided into six parts, as education, culture, welfare and consultation, medicine, employment, and legal services. The theoretical research checked the background of public administration responsiveness, and draws conclusions and political implications from the analysis of the survey. The results show that the responsiveness of the Korean government is highest in education and culture. Chinese brides feel lower responsiveness the older they are. There is also a clear difference between Chinese and Chinese-Korean brides. The Korean government should provide a greater variety of programs and make a cooperative network for them in order to help them adapt to Korean society.

본 연구에서는 산림에 대한 기능을 공익적 기능과 경제적 기능으로 구분하여 의사결정의 구조를 응용한 계층분석법(AHP)을 통해 전문가들을 대상으로 산림가치의 중요도 및 우선순위에 대한 분석을 시도하였다. 분석결과, 첫째, 산림기능의 1차적 수준인 공익적 기능과 경제적 기능의 1단계 분석에서는 공익적 기능이 경제적 기능보다 더욱 중요한 것으로 인식하고 있는 것으로 나타났다. 둘째, 산림기능의 가치에서 2차 수준에 대한 2단계 분석에서는 공익적 기능은 환경보전기능, 경제적 기능은 산림소득기능이 더욱 중요한 것으로 나타났다. 셋째, 산림기능의 가치에서 3차 수준으로 3단계 분석에서는 환경보전기능은 자연환경보전기능, 산림서비스기능은 산림레저기능이 더욱 중요한 것으로 나타났다. 그리고 산림소득기능은 임업경제기능, 지역경제활성화기능은 지역소득창출기능이 더욱 중요한 것으로 나타났다. 마지막으로, 산림기능에 대한 종합중요도 및 우선순위에 대한 종합분석에서는 자연환경보전기능이 가장 높은 중요도를 차지하는 것으로 나타났으며, 다음으로 전체 측정요소의 중요도가 ‘자연환경보전기능 → 산림레저기능 → 생물환경보전기능 → 건강증진기능 → 임업경제기능 → 지역소득창출기능 → 산림권리기능 → 일자리창출기능’의 순으로 나타났다. The research divided the performance of forests into a public group and an economic group. The research analyzed the importance and priority of forest values through AHP based on the structure of decision-making, conducting a survey of experts in related fields. First, the first stage of the analysis of the first level of the public performance and economic performance of forest values revealed that the former is considered more valuable than the latter. Second, during the second stage of analysis of the second level of forest values, environmental conservation and forest income turned out to be meaningful for public performance and economic performance, respectively. Third, the third stage of the analysis of the third level of forest values reported that environmental conservation performance values nature conservation while forest income performance regards forest leisure performance as important. Added to this, forest income again considers forestry economic performance significant while the revival of the regional economy believes regional income creation to be important. Lastly, the synthetic analysis of the importance and the priority of forest performance showed that nature conservation performance is the highest priority followed by forest leisure performance, bioenvironmental conservation, health improvement, forestry economy, regional income creation, forest rights, and job creation.

소방공무원과 건축물 관계인의 소방검사 업무 만족도에 관한 연구

이종열(Jong Youl Lee)(李鍾烈),배수연(Soo Yeon Bae)(裵洙延) 위기관리 이론과 실천 2012 Crisisonomy Vol.8 No.2

This study is to show how satisfied firefighters and building managers are with fire inspections and their differences using a questionnaire. As a background, current realities and policies are analyzed. One interesting finding is with respect to contracting-out of the inspection work. Most firefighters prefer it, but most building managers oppose it. The reason why they are against it is that it produces a cost burden. Both parties agree on such desirable directions like active participation of building managers, reducing the scope of inspection, enhancing expertise of inspectors, clarification of punishment, and avoiding overlapping inspections. 본 연구는 소방검사에 대한 현 실태 분석 그리고 소방공무원과 건축물 관계인이 현재 시행하고 있는 소방검사 업무에 대해 얼마나 만족하고 있는 지에 대한 설문조사 실시와 그 결과를 비교 분석한 것이다. 분석 결과 두 집단의 큰 차이는 소방검사 업무의 전면적인 민간위탁에 대한 견해이었다. 소방공무원은 찬성하는 인원이 많았으나, 건축물 관계인은 반대하는 인원이 많았다. 많은 건축물 관계인은 소방검사 업무를 민간에 위탁할 시 일어날수 있는 비용부담을 가장 우려하고 있었다. 이러한 우려를 해소하기 위해서는 지속적인 연구를 통해 건축물 관계인이 만족할 수 있는 대안을 마련해야 한다. 소방공무원 및 건축물 관계인 모두가 만족할만한 소방검사 업무의 방향은 소방검사 개념의 재정립, 건축물 관계인의 능동적 참여 유도, 소방검사 대상 축소 및 검사 항목 조정, 소방검사 인력의 전문성 확보, 처벌규정의 명확화와 처벌의 실효성 확보, 관계기관의 중복된 합동점검 지양, 민간위탁(종합정밀점검)대상의 합리적 선정 및 확대 등을 들 수 있다.
