스마트 폰 사용자 수가 2000만명 이상이 됨에 따라 모바일 맵 서비스에 대한 수요가 급증하고 있다. 한편, 모바일 기반의 맵 응용의 개발을 위해선 WINDEV Mobile 17과 같은 유료 개발 환경이 있지만 자동화 지원 경도가 미약하여 맵 응용의 생산성이 떨어지고 유지·보수 기간도 많이 소요된다. 우리가 설계하고 구현한 MobileMapGen은 GoogleMaps API를 사용하며 서버 측을 위해 CMS(Content Management System)인 Drupal 환경에 사용 가능 한 모듈들을 생성하고 클라이언트 측엔 iOS 앱을 생성해 맵 응용에 대한 생산성을 향상시켜 준다. 맵 컨텐츠와 그와 연관된 컨텐츠들을 함께 제공하는 모바일의 맵 응용 생성기인 MobileMapGen과 달리 WINDEV Mobile 17, MobilForms, 그리고 VisualStudio.NET는 맵 인터페이스를 지원하지 않거나 위치 정보 형태만을 표시한다. 그렇기 때문에 사용자가 원하는 지형/지물 컨텐츠 타입을 생성하거나 맵 상에 표시하고 관심의 대상인 지형/지물과 연관된 컨텐츠들을 검색할 수 없다.

An experimental investigation has been made to study the two-phase phenomena and heat transfer characteristics in porous media heated at the top and cooled at the bottom at one dimensional steady state. Experiment is conducted using glass beads and sand of mean diameter 0.9mm and 0.3mm respectively contained in a 22cm long, 5cm inner diameter Pyrex glass tube. Distilled water is used as a working fluid. Result of experiment shows that the two-phase zone is very sensitive to the system insulation and its length increases with the increasing heat flux, which is contrary to a pre-researcher. At this stage, this contradiction is supposed due to the variation of capillary pressure with the varying heat flux. The two·phase zone length of the lower permeability sand system is larger than that of the higher permeability system filled with glass beads. The total effective thermal conductivity of the system is enhanced with an increasing two phase zone length.

Electric Power cable is the apparatus that receives electric power from the Korea Electric Power Corporation and supplies electric power to electric train and annex facilities of each railway station. With substantial ripple effect during power blackout accidents, such power blackout accidents must be coped with by discriminating the status of insulation deterioration of electric power cable in advance. Discrimination of insulation deterioration of the electric power cable is normally executed while the power is disconnected and it is very difficult to discover, at early stage, the insulation deterioration of the power cable in operational state since the duration of inspection is limited. This research aims to consider method of diagnosing the insulation deterioration of electric power cable in On-Line state rather than diagnosis in Off-Line state in order to secure reliability of power supply by reducing duration of power blackout (accidental blackout and blackout during works) and by seeking reduction in equipment and manpower used in diagnosis of deterioration through prevention of the accident itself prior to occurrence through early restoration of accident due to insulation deterioration of the electric power cable and assessment of performance of the cable under operation.

Electric car tract plays the role of supply high electric power to the electric car from the substation by using Pantograph of the electric car. It is always exposed to the external atmosphere, which results in quite substantial fluctuations in current and voltage during operation of electric car. This generates possibility of occurrence of accident at all times. Since range of wiring metallic globe installed on the catenary cannot achieve complete electrical contact, accidents are occurring due to circulating current caused by arc caused by incomplete contact due to occurrence of hairline fracture of Pantograph due to pressure or vibration of wiring. Furthermore, rapid increase in the operational current due to increase in the operational frequency of the electric car is causing erosion and short circuit of the metallic globe at the contact points. This study on arc is generated as current transmitted out of the substation courses through power line or wiring metallic globe other than the main circuit as the current is being collected at the electric car through feeder and feeder divergence device. Accordingly, since heat generated by the arc becomes the cause for generation of circulating current due to melting of metal or softening of metal due to increase in temperature accompanying increase in contact resistance, this research shall describe causes and measures against occurrence of circulation current.
