최근 국제적인 여건과 사회적인 상황이 급변하여 대량생산-대량소비지향으로 인한 폐기물의 대량방출사회에서 지구환경보전을 중시하는 사회로 전환되어 가고 있다. 지구환경의 보전을 위하여 다양한 분야에서 각종 논의가 진행되고 있는 가운데 건축분야에서도 지구기후변화에 영향을 미치는 것으로 알려져 있는 이산화탄소배출의 억제와 폐기물 삭감 등에 대한 관심이 증대되고 있다. 최근 관심이 집중되고 있는 건축물의 장수명화와 리모델링도 이러한 움직임과 궤틀를 같이 하는 것이다. 물론 리모델링은 신축시장의 급감에 따른 대체시장으로서 검토되고 있는 측면이 더 크게 작용하고 있는 것도 사실이지만, 그동안 신축에 대한 집중적인 투자에 중점이 두어져 재고건축물에서 간과해 왔던 유지관리와 리모델링에 대한 중요성 인식이 결부되어 있다고 보여진다. 사실 지금까지 리모델링이 전혀 이루어지지 않았던 것이 아니라 일반건축물 부문에서는 상당부분 이루어져 왔으며, 공동주택 부문에서도 극소수 이루어져 왔다. 리모델링에 대한 정의와 개념을 어떻게 보느냐에 따라 많은 차이가 있을 수 있지만, 리모델링은 건축물 또는 외부공간의 성능 및 기능의 노후화나 진부화에 대응하여 보수, 수선, 개수, 부분증축 및 개축, 제거, 새로운 기능추가 및 용도변경에 이르는 광범위한 행위를 포함한다. 리모델링을 통하여 건축물의 성능을 유지하거나 향상시켜 쾌적하고 건강한 건축물의 재고 를 구축함과 아울러 건강한 지역환경을 조성하여 국민생활의 질적인 향상을가져옴으로써 환경을보전하 고 자원낭비를 줄여 지속가능한 건축물과 사회를 만들어 갈수있도록 하는 것이다. 건축물에서 리모델링을 하게 되는 동기는 시간이 흘러 물리적인 측면이나 기능적인 측면에서 노후화가 발생하거나 기능적인 요구가 변화함에 따라 건설당시의 성능이나 기능유지가 어렵거나 건설당시의 기능만으로는 요구조건을 만족함 수 없기 때문에 건설 당시의 수준을 유지하거나 새로운 요구에 적합하도록 향 상시키기 위해서는 물리적 또는 기능적인 개선이나 개량이 필요하기 때문이다. 물리적인 개선이나개량을위하여 중요한것은건축 물을 구성하는 자재나 부품의 수명문제이다. 수명의 길이차이가 건축물의 리모델링에 영향을 주고 있을 뿐만 아니라 서로 다른 수명의 자재나 부품의 접합상태가 리모델링 공사에 많은 영향을 미치게 된다. 리모델링 공사가 신축공사의 70-80% 정도의 공사비가 소요되기 때문에 리모델링 공사가 어렵다는 업체의 불만은 바로 이러한 점을 극명하게 드러내는 좋은 사례이다. 본 고는 이러한 측면에서 건축물의 장수명화를 근간으로 한 설비의 리모델링을 용이하게 하기 위한 건축 계획 및 구법에 대하여 고찰하고자 한다. 그리고 본 고는 기존건축물의 설비자체의 보수나 개수를 용이하게 하는 것에 초점이 맞추어진 것이 아니라 건축설계 및 시공시에 향후 설비부분을 용이하게 개.보수할 수 있도록 배려하는 측면을 중심으로 설명하였다.

Contemporary hospital has more and more extension because the growth and change of hospital has to respond the various needs. For expanding, the sky bridge(sky walk) becomes one of the method to interconnect two or more buildings on the air. Sometimes the designers don't know exactly how the sky bridge works after construction. Beyond the role of interconnecting two buildings, the role of sky bridge is transformed the main axis of pedestrian in the whole hospital organization. This scope of analysis is about the sky bridge of Hanyang University hospital. The first method is the investigation of the utilization in this time. The second is the analysis of design drawings got form the designing of the past(1994-1998). From this analysis, the conclusions are followings.；The designer who wants to apply the sky bridge should more consider about, 1) how the sky bridge impacts the whole spatial system such as the pedestrian, patients, physicians, service's facilities etc. 2) what the inside of sky bridge has something such as natural light, ventilation, and the height, depth, width of aisle, the sign for seeking orientation. etc. In future the research relating sky bridge should be studied some hospital as well as one hospital for comparing the characteristics of the concepts and organizations

This study examined the remodeling characteristics of traditional urban housing for lease focusing on Hanok in the traditional urban housing neighborhood of Bukchon. Furthermore, the space syntax was used as the main analytic approach to objectively revealing the change in social properties of each spatial element because each room forms its status in the structural relation with many rooms and accommodates the special change in traditional housing and modern life. These findings revealed the following; spatial division between the landlord and tenant results in a hierarchical change in the yard and main hall and strengthens the privacy of the space of the landlord.

SBAS is a satellite based navigation correction system that provides correction information and integrity information of GNSS signal through geostationary satellite based on analysis of GNSS signal in ground station. KASS, a Korean SBAS, is aiming at the APV-1 class SoL service in 2022. Sufficient ground and flight tests must be performed in advance to provide SoL services. However, since KASS, the Korean SBAS, has not yet been added in Korea, specific detailed evaluation items are not presented. EGNOS, which is expected to be the most compatible with KASS and is being serviced after its development, has already been evaluated. In this paper, we analyze the regulations applied to EGNOS construction and analyze the criteria of ground and flight test evaluation items required for flight testing, which is expected to be referenced to the flight inspection process in the future.

Because of the rapid rising of water related disasters due to the global warming, the extreme design criteria of levee construction for severe flood has been applied in several developed countries such as USA and Netheland. In Korea, the national river restoration projects were carried out on 4 major rivers in recent several years. The projects consisted of riverbed dredge and levee reinforcement, and new construction have caused wide change of river environment. However, concrete countermeasures for levee safety and river management have not been suggested until now. Therefore, this study assesses the levee safety of Yulji levee located in Hoechon, Nakdong Basin, where the Levee Seepage Monitoring System installed. The stability of levee is assessed based on the simulation performed by SEEP/W(2D unsaturated seepage model) and the simulated results are compared with the observed data. The effects of the flood wave and levee shape on the levee safety are investigated through several simulations.

Using existing tunnel for section enlargement and remodeling is being considered as an optimal alternative in order to solve traffic jam in tunnel. The existing method has been performed while blocking the traffic flow. Recently, New enlargement method was developed which can maintain traffic flow during the construction by using protector. It can minimize social loss due to keeping traffic flow. On the other hand, installing and operating protector can cause economic disadvantages. So, social cost estimation considering traffic flow should be considered for relevant economic evaluation of tunnel section enlargement methods. This paper presents the social cost estimation method of tunnel section enlargement methods considering traffic flow. In addition, to compare economic efficiency existing method with new method, suggested method was applied to Maebong Tunnel.

When Korea opened its ports and underwent Japanese colonization, many Japanese style houses were built in Korea. Following Korea's independence from Japan, Koreans began to reside in these houses. The objective of this study is to examine the current state of Japanese style residence areas and Japanese style houses in Korea, and to determine the change in the characteristics of dining kitchens that have taken place since Koreans have lived in them. In the process, while assimilation occurred, there was also a conflict between the residential lifestyles of the two cultures, developing into a state where two housing cultures co-existed. The dining kitchens showed the most sensitive adjustments to social changes, facilitating a number of important changes in the process of modernizing houses. In this regard, the intention is to determine how the dining kitchens responded to other areas within the house as they were being transformed. Research for this study is based on previous studies that were carried out in 1991 on Japanese style houses, in order to clearly define the process of change chronologically rather than from a single examination. In consequently, From the process of changes where from a conventional kitchen to DK anger, 1) The public space - wooden floor, living room, etc - had been formed in house spaces. 2) In the lifestyle, privacy secured. It was separated each functional spaces that greeting space for guests and family's space in the lifestyle. 3) The cause of variation could be summarized that differences of living style, a change of life and fuel.
