Since the urban subway is normally constructed under the groundwater level, the drainage system will be one of the most important factors during maintenance period. Therefore, to investigate suitability of the design approach and the construction specification, the inflow and the contents of the groundwater in the Route 5 of Seoul subway system are analysed. From these, the possibility of the design improvement and the economy of the maintenance cost are proposed.

본 연구는 서울·평양 공동 올림픽 개최와 스포츠 저널리즘의 역할에 대해 분석하는데 목적이 있다. 연구방법은 질적연구 방법으로 스포츠를 담당하는 국내 신문기자와 방송 기자, PD에 대한 심층 인터뷰(in-depth interview)를 통해 공동 올림픽에 대한 기자들의 인식을 파악 했다. 첫 번째, ‘한국 스포츠 저널리스트의 남북 공동 올림픽 개최에 대한 인식’에 대한 연구결과는 1) 공동 올림픽 개최에 대한 긍정적인 면을 정치, 경제, 사회적인 측면에서 나타내고 있다. 2) 남북 스포츠 단일팀 사례를 제시하며 전 세계에 알렸던 남북 화합과 공동 올림픽 개최에 대한 효과를 매우 긍정적으로 바라보고 있다. 3) 변화 무상한 북한의 분의기를 경험해 볼 수 있고 남북 공동 올림픽 개회가 가져올 평화의 분위기를 예측하고 있다. 두 번째, ‘편집국(보도본부)내 남북 공동 올림픽 개최 취재보도와 관련 의사결정 과정’ 연구결과는 1)편집국내 의사결정 과정에서 부정적인 판단 없이 적극적인 사전준비와 취재진의 판단으로 프로그램 기획 및 개발 할 수 있는 분위기가 잡혀 있음을 알 수 있다. 2) 공동 올림픽의 의제 설정은 진보나 보수의 입장에서 벗어났으며, 남북 엘리트 선수 육성시스템에 대한 보완점을 제시하였다. 3) 의제설정 과정에서 보다 객관적인 자세로 취재에 임하고, 북한 스포츠에 대한 궁금증을 풀어갈 저널리스트로서의 역할도 제시했다. The purpose of this research was to analyze the role of sports journalism in Seoul and Pyeongyang co-hosting the Olympic Games. This research was done qualitatively as sports journalists, broadcast reporters and television producers were interviewed in depth in order to investigate the preception and awareness of co-hosting the Olympic Games among the media personnel. First of all, the results regarding ‘the perception among the South Korean sports journalists concerning the South and the North Korea co-hosting the Olympic Games’ were as following: 1) positive opinions in regard to the co-hosting are being shown in political, social and economical aspects. 2) showing the harmony between the South and the North with the case of a unified team in the past, the effects of co-hosting the Olympic Games are being viewed very positively. 3) could be an opportunity to experience the ever-changing atmosphere of North Korea, and it is also being anticipated that the co-hosting would bring peace mood to the Korean peninsula. Secondly, researching the ‘decision making process in the editorial department (or the newsroom) regarding reporting of co-hosting the Olympic Games’ yielded the following responses: 1) along the decision making process within the editorial department, the tone is set so the reporters can actively prepare and use their discretion to plan and develop a program without any negative perception. 2) the agenda setting in regards to the co-hosting has become independent of any political views, and suggested the ways to improve the elite athlete development system both in the South and North Korea as well. 3) the role of journalist which could satisfy the curiosity about the athletics in North Korea was suggested during the agenda setting process, as well as the importance of taking more objective views in reporting.

최근, 철도 건설의 활성화로 국내외적으로 장대 터널이 증가하고 있다. 그러나, 장대 터널에서 화재가 발생할 경우, 많은 인명 피해와 경제적 손실을 초래한다. 따라서, 터널 화재로 인한 콘크리트 구조물의 단면 손상 정도를 예측하기 위해서는 철도터널에 적합한 화재 곡선을 얻는 것이 중요하다. 본, 연구에서는 이미 제안된 4종의 화재 곡선을 사용하여 수치해석을 실시하였으며, 콘크리트에 대한 온도변화, 폭열 현상 등을 분석하였다. 그 결과 4종의 화재 곡선 가운데 철도터널 화재를 모사할 수 있는 곡선은 RABT곡선 및 HMC인 것으로 분석되었다. Recently, Long railroad tunnel increases due to the activation of the railroad construction. But the fire occurs in a long railroad tunnel, the many damage of human life and the economic losses are caused. Accordingly, it is important that the suitable fire curve for the railroad tunnel is selected to predict damages of the concrete structure. In this study, the finite element analysis was conducted by using the already suggested 4 kinds of fire curves. And the temperature change and the spalling of the concrete were analyzed. As a result, the RABT curve and HMC can be show the railroad tunnel fire phenomenon similarly among the 4 kinds of the fire curves.

Resently, Fiber Reinforced Concrete is used for not only preventing crack of concrete but also reinforcing general methods. Steel Fiber and PP(poly-propylene) Fiber are usually used as fiber reinforced materials. However, using these materials for shotcrete on Railway tunnel can cause some problems such as damage of pressure hose and shotcrete rebound. In addition, Steel fiber is an expensive material and it can cause safety problems during applying to shotcrete. PP Fiber can cause a problem in fiber balling during applying to shotcrete railway tunnel construction. A purpose of the research is applying a development of PET(Poly Etylene Terephtalate) fiber by recycling pet bottles to the shotcrete tunnel exposed to explosion spalling. To investigate the reinforcement effect of the PET fiber, some basic tests are accomplished to physical properties and explosion spalling by fire. As a result of the tests, a concrete mixing the PET fiber has stronger resistance effect in the explosion spalling by high temperature than another strong fiber concrete does, and that the former concrete is also equal or more effective on the result of the above tests to physical properties like compression and strain than the latterone is demonstrated.
