기후변화는 지구 온난화와 같은 인위적인 변화와 기후 자체의 자연적인 변동성에 기인하고 있으며 기후변화의 영향으로 인해 물관리 분야에도 영향을 받고 있다. 이러한 기후변화의 영향은 가용 수자원량의 예측과 이를 관리하는 측면의 불확실성을 증가 시키고 있으며 미래 물관리가 더욱 어려울 것으로 전망되고 있다. 이에 본 연구에서는 기후변화에 대응한 수자원의 종합적인 관리 차원에서 시공간적 물수급 불균형 해소를 위한 방법론을 제시하고자 유역 물관리 모형인 KModSim을 이용하여 낙동강유역을 대상으로 수자원 네트워크를 구축하였다. 유역의 자연유량을 산정하기 위하여 SWAT 모형을 이용하였으며, 현실적으로 유역의 물관리 문제에 접근하기 위해서 낙동강 유역의 수리시설물, 생 공용수 및 농업용수, 댐용수 및 하천수 점용허가 등의 수리권 자료에 근거하여 KModSim을 구축하였다. 미래 기후변화 시나리오(온실가스 배출이 현 수준에서 지속될 것으로 가정한 균형적 발전 시나리오인 A1B 사용)를 적용하였으며 현재(1980~2009년)와 미래(2011~2100년)를 각각 30년씩 구분하여 기후변화에 대한 생활 공업 농업용수의 수요량 변화, 하천유지용수의 공급 변화, 다목적 댐 모의 운영 결과를 검토하였다. 낙동강 유역의 상류 다목적댐의 용수공급 능력은 2040년 초반부터 저류량이 감소 등 물공급에 심한 영향을 받을 것으로 전망되었다. 이와 같은 기후변화의 영향은 수요량에 대응하는 저수지의 공급능력에 영향을 주게 되어 물공급 시설의 운영에 어려움이 있을 것으로 전망되었다. 농업용수에 대한 기후변화의 영향평가 결과 또한 2041년부터 2070년의 기간에 부족이 발생하는 것으로 모의되었다. 생활과 공업용수의 물공급은 기존의 물공급 시설 투자 덕분으로 기후변화의 영향이 두드러지지 않은 것으로 나타났으나 일부 지역은 기후변화에 영향을 고려하지 않더라도 취약한 것으로 모의 되었다. 하천유지유량의 경우 지류가 본류에 비해 하천유지유량의 확보가 어려운 것으로 나타났지만 양적으로는 본류가 부족량이 더 많은 것으로 모의되었다.

A civil-military facility sharing project is a part of mutual cooperative efforts, which enables the military to use any civilian (local government or company) or a civilian to use any military facility. Such facility sharing project may reduce or clear possible conflicts with the local residents in the surrounding area of a military facility while being available to save budgets for new construction or maintenance of a defense or military facility. Various measures have been proposed for institutional resolutions on conflicts with the local residents in the surrounding area of a military facility. This study collects and organizes previous cases of the civilian-military facility sharing projects, and analyzes the characteristics of such cases based on the project types. In addition, by organizing and proposing the project characteristics, plans (ideas) and determination criteria to expand and vitalize are presented regarding the project types having restrictions. AHP technique is employed to research on the matrix for the project feasibility determination. Also, the opinions organized through the cause analysis are categorized and presented as a project for the expansion and vitalization of future project. According to the rearch result, Type I, II and III are determined to be projects that can be implemented without difficulties. Type IV, on the other hands, is determined as not illegal, yet inadequate so that some legal and institutional complements are required to expand and vitaliza this facility sharing project.

The purpose of this study is to analyze the interior color characteristics of elderly housing facilities in Korea. For this purpose, a filed survey was conducted between October 16 and October 25, 2003, visiting 10 elderly housing facilities. A three step analysis of the facilities was involved. First, floor, walls, ceiling, base boards and doors in common spaces were examined for the color scheme using the 'Pantone for Fashion and Home Color Guide' for each room. Measured Pantone numbers were converted to RGB color using 'Chooser 3.0 of Pantone, Inc.' Finally, the conversions were recorded as Munsell numbers. The results are as follows. First, the brightness used in elderly housing facilities ranges from high value to low value while the chroma ranges from the middle chroma to low chroma. The warm colors of Y and YR are mainly used, followed by GY and R. Second, the colors used for elderly housing facilities are found inter-related. For example, the main color in the lobby is also used for corridor and used again in dining room, library, and treatment room. Third, in terms of the color scheme, it is best help the elderly, who generally have lower recognition capability, by highlighting the distinction and attention by using the dearly distinctive accent color for the transition space, edge of the hallways or in front of the door to the units and having different color for each floor. But in most facilities except one or two, this consideration is ignored. Fourth, there is difference in color selection between elderly housing with low and high rental value. Only one facility, the most high priced one, has aggressive color arrangement, and the others show very little consideration of the elderly's needs.

Using multi beam echo sounder, side scan sonar and scuba diving equipment, ceramic type, uneven type and semicircle-ramus type reefs into sandy bottom were ascertained, the depth of submersion in 7.2-10.3m on the coast of Gangneung, East of Korea, forty uneven type artificial reefs(AR) were totally buried into the sandy bottom. Two of five semicircle-ramus type ARs had only of their top area exposed. For most of the 45 ceramic reefs, only the upper 25-150cm of ARs were visible. The burial pattern is different in west and east side of the reefs, where the east side is deeply buried compared to the west side. From these results. it is recommended that sufficient analysis of bottom structure and materials especially in the sandy sea area should be undertaken in order to determine the best type of artificial reefs to be deployed and the best location for depoloyment.

국도는 사회간접자본 중 하나로서 지속적으로 관리되어야 그 기능을 발휘할 수 있는 국가의 중요한 자산이다. 지금까지는 국도를 포장관리시스템이라는 체계로 관리하여왔다. 이 포장관리시스템은 시설물유지관리차원에서 사회기반시설을 관리하는 것으로서 주로 관리자 관점에서 공학적 판단을 기준으로 최소의 비용으로 공용수명을 최대화하는 모델이다. 그러나 경제발전으로 국민의 소득수준이 올라감에 따라 기본적인 욕구가 해결되어 이제는 납세자로서 국민의 동의는 국가의 정책을 결정하는데 중요한 변수로 작용하기 시작했다. 따라서 사용자 관점의 평가는 이러한 요구의 수준을 측정할 수 있는 중요한 척도가 되었으며 이에 기반한 LoS(Level of Service, 서비스 수준)라는 지수를 시설물 자산관리에 활용하려는 여러 가지 시도가 있다. 이 논문에서는 기존 국도포장관리시스템의 정보모델과 KTAM-40(Korea Total Asset Management-40)이라는 자산관리 정보모델을 비교하여 LoS의 필요성과 도로포장자산관리에서 LoS가 사용자 관점을 반영하는 방식을 조명해 이의 장점을 밝히고자 한다.

최근 기후변화의 영향일 것으로 추정되는 이상가뭄의 발생빈도가 잦아지는 상황에서 이에 대한 대비책으로서 댐의 비상용량을 비상용수로 공급하는 방안이 조심스럽게 제기되고는 있으나 현재까지 국내에서는 비상용수에 대한 명확한 정의조차 제시되지 않는 등 다소 생소한 개념이라고 할 수 있다. 본 연구는 비상용수 공급의 국내 외 사례와 비상용수 공급편익 산정에 관한 국내 외 연구를 검토하여 댐에 의한 비상용수 공급의 가능성과 가치를 평가하는 것을 목적으로 한다. 비상용수의 수요는 정기적으로 발생하지 않는 특수한 경우이고 용수공급을 대체할 만한 대안이 거의 없는 극한 상황에서 발생한다. 그러므로 생 공용수의 편익산정 방법에 일반적으로 이용되는 대체시설비용법과 같은 편익산정 기법을 적용하는 것은 여의치 않을 것으로 판단된다. 그리하여 본 연구는 비상용량이 사용될 때의 갈수빈도와 갈수피해액의 관계를 설정하고 피해경감액을 추정함으로써 연평균 편익을 산출하는 방안을 검토하는 방안을 제안하고자 한다. 비상용수 공급편익의 합리적인 계량화하기 위해서는 적절한 이수안전도의 설정과 이에 따른 이수기능의 평가가 선행되어야 한다. 그러나 아직까지 갈수규모에 따른 비상용수 공급편익의 산정방법에 대한 명확한 기준이 마련되지 않은 실정이다. 따라서 향후 비상시 댐의 이수기능을 최대한 활용하고 이에 대한 올바른 가치평가를 위해서도 관련분야에 대한 기초연구가 시급히 이루어져야 할 것이다.

In this study, interviews are held with the faculties of two elementary schools on narrow sites located in Seoul to examine the existing problems of the elementary school on narrow site and the need for the new facilities of the elementary school on narrow site in order to derive the implications for the planning guidelines of such school construction. As a result of the survey, it was found that the substitutes of the playground installed in the elementary school on narrow site were not suitable for physical play activities, physical education class activities, and other curriculum operations. In order to secure an adequate physical activity an space for elementary schools, faculty members were demanding that the entire floor or rooftop of the school building be spatialized for physical activities. Additionally, problems such as noise generation and the lack of special rooms and public space were occurring in the elementary schools on narrow sites and are being deteriorated by accommodating an over number of students, and therefore policies are required to ensure that the appropriate number of students are maintained in the case of the schools on narrow sites.

According to the Framework Act on Sustainable Infrastructure Management, which has been enforced since 2020, reservoirs should be managed to minimize life cycle costs caused by aging through preemptive management such as systematic maintenance and performance improvement. For maintenance in consideration of the life cycle, it is essential to derive the end of life due to continuous performance degradation as the common period increases. For this purpose, it is necessary to develop a performance-predicting model for reservoirs. In this study, a reservoir was divided into main complex facilities to develop a model for the maintenance of the life cycle. A model was developed for each facility. For model development, maintenance information data were collected under management by the Rural Community Corporation. The data available for model development were selected by analyzing the collected data. The developed model was used to predict the expected life expectancy of the reservoir in the current maintenance system and the expected life expectancy in the case of no action. By using the developed model, it is expected that it will be possible to support decision making in operation management and maintenance while considering the life cycle of the reservoir.

In recent years, many infrastructure have been rapidly aging around the world, which grows interest in the maintenance of the infrastructure. Among the social infrastructure, bridge is a very important structure to transport lots of human and various products. The performance evaluation of bridge can be divided into the condition evaluation and safety evaluation, proposed by Korea Infrastructure Safety and Technology Corporation. However, there are no separate criteria for the performance evaluation of three-class bridges. In general, the performance of bridge is dominated by the results of the condition evaluation, which is lower than that of the safety evaluation. Therefore, this study assessed the correlation between the condition evaluation of superstructure and bridge and also between the condition evaluation and the safety and load-carrying capacity of bridge. The results of the study would provide a basic data for the more quantitative and higher relevant performance evaluation of the existing bridges, particularly for three-class bridges.
