The Industrial Revolution brought a variety of new forms of structure, and as a group they are usually called 'industrial architecture'. Steam engines contributed greatly to architecture with a unique structure called 'water tower' to provide water for steam engines, especially the adoption of it. This study is to examine the changes of the building materials and architectural features of the water towers of railway stations built in the early twentieth century in South Korea. This study also attempts to describe the modern features of the industrial architecture, which did not get a chance to be noticed. Through this examination on water tower, which is a part of industrial architecture with sheer integration of function and pure geometric form, we would like to find the meaning of modern architecture in Korea. As we can see in the Korean oldest railway station water tower constructed in masonry at Yeonsan Station in 1911, early water towers were divided into the masonry machine room and the steel water tank. However, the masonry structure was soon turned into concrete structure with its formal features maintained as it was. The steel water tank was also replaced with concrete structure. As a result, while its basic structure remained, concrete structure had substituted for the every components of water tower. Concrete-built water towers were the high-tech architecture of that time and the most perfect structures built in concrete. Nevertheless, the perfection of the water tower form and the technology it attained were not transferred to other modern and contemporary architecture in South Korea. Since the subject to railway station water towers was the Japanese government, and steam engines were replaced with diesels in the midst of a complicated domestic situation after the independence, the need for water towers in railway stations disappeared and therefore, it became ignored and was difficult to look over the architectural features and values of early railway station water towers.

Energy Saving Methods in existing railway vehicle are considered by active approach such as regenerative energy storage and utilization, eco driving, etc. On the other hands, energy saving measures in railway station are operated by passive method such as reduction of operating time in ventilation system, cooing system and power equipment. To reduce energy and for independence in railway system, it requires an active energy saving measures. It needs to its own power source besides the power source of electric supply company such as renewable energy and regenerative energy and take the advantage of power storage system and stored power are used in optimum time. This paper deal with 3-level NPC inverter and T-type NPC inverter that used in various multi-level topology applicable to the railway system.

한국에서 철도역은 열강의 수탈 및 대륙침략을 위한 목적으로 설치되었으나 한편으로 역이 설치된 지역에 있어서 교통수단의 중심이자 지역사적 사건의 무대로 기능해왔다, 그러나 지속되는 구조조정과 철도개량으로 기존의 철도역은 큰 변화를 겪고 있다, 철도역의 지역사적 위상과 기억을 재현하기 위한 수단으로 사진은 여러 유용성을 지니고 있으나 다른 매체에 비하여 기록 관리가 이뤄지지 못하고 있으며, 분단국가라는 특수성으로 인하여 사진으로 이를 남기는 작업도 어려운 상황이었다. 본 연구는 이러한 상황에서 철도역을 사진으로 기록하기 위한 방안을 제안하기 위하여 우선 무엇을 기록할 것인가에 대한 접근을 시도했다. 선행 기록화 연구에서 주로 활용된 업무 및 기능의 분석으로는 철도역과 직 간접적으로 연관을 가진 행위 및 시설물을 재구성하기 어려운 한계를 극복하기 위해 철도역의 가치를 분석하고, 이러한 가치를 기반으로 각각의 기록화 영역을 설정하여 각각의 기록화 영역별로 어떠한 세부대상이 기록화 될 수 있는지를 구체적인 사례로 제시했다. 또한 기록화 영역의 설정 과정에서 만들어진 계층성을 기반으로 분류체계에 적용하고, 세부대상의 변화에 따른 분류체계의 추가 및 수정에 대한 사례를 제시했다.

The purpose of this study is to analyze the principal causes of increases in air temperature on platforms of railway station. We analyzed the distribution of air temperature on Shinkansen platforms at Station 'A' using Computational Fluid Dynamics (CFD). We focused on the factors that influence the temperature dynamics associated with heat generated by trains and station buildings and their effect on the ambient temperature on platforms. In the case of heat generated by trains, air temperature on Shinkansen platforms increased by 4 to 7 degrees compared to when trains generated no heat. When a 50-m high station building was located on the windward side of the platforms, air temperature on Platform X was 2 degrees higher than when the station buildings were absent. Air? temperature on platforms VII to IX increased progressively, and the maximum air temperature on platform VIII was 3 K higher than if station buildings were absent.

도시철도 역사의 안전사고는 사고 당사자에게 피해를 주는 것에 그치지 않고 대중교통 이용을 기피하는 원인이 되기도 한다. 본 논문은 도시철도 역사에서 발생하는 안전사고를 감소시키고 이를 근본적으로 예방하기 위해 도시철도 역사 설계 시 고려해야 할 디자인 요소를 도출하는 데 그 목적이 있다. 특히 최근 새로이 등장하고 있는 모든 사람을 위한 디자인, 즉 유니버설디자인 관점에서 도시철도 역사의 안전을 위해 역사 설계 시 고려해야 할 요소를 도출하고자 한다. 이를 위해, 본 연구는 도시철도 역사에서 발생하는 안전사고를 유형별로 분류하여 위험도를 분석하고 사고 원인을 분석하였다. 이를 통해, 도시철도 역사에서 발생하는 안전사고와 관계가 높은 요소를 도출하고, 이를 유니버설디자인 관점에서 그 중요도를 고려하여 디자인 요소를 도출하였다. 본 연구 결과는 도시철도 역사의 개량 및 설계 시 안전사고를 최소화 하고 예방할 수 있는 디자인을 위한 기초자료로 활용될 수 있을 것이다.

As accident rate have been reduced into half since 2005, no train accident fatality occurred in recent year. Level crossing accident also been reduced that no more than 5 fatalities occurred every year. As a result 98% of accident fatalities occurred in station and track. So railway station safety measures are more and more important but only few research have been done on railway station safety. In this study status on safety measures on railway stations are reviewed and basic research have been done based on expert interview for the development of new safety measures.

Insight into behaviour of pedestrians as welt as tools to assess passenger flow condition is important in such instances as planning and geometric design of railway station under regular and safety-critical circumstances. Algorithm for passenger flow analysis based on DEM (Discrete Element Method) is newly developed. There are lots of similarity between particle-laden two phase flow and passenger flow. The velocity component of 1st phase corresponds to the unit vector of calculation cell, each particle to passenger, volume fraction to population density and the particle velocity to the walking velocity, etc. And, the walking velocity of passenger is also represented by the function of population density. Key algorithms are developed to determine the position of passenger, population density and numbering to each passenger. To verify the effectiveness of new algorithm, passenger flow analysis for the basic models of railway station is conducted.

Advancement in information technology have enabled applying vision sensor to railway, such as CCTV. CCTV has been widely used in railway application, however the CCTV is a passive system that provide limited capability to maintain safety from boarding platform. The station employee should monitor continuously CCTV monitors. Therefore immediate recognition and response to the situation is difficultin emergency situation. Recently, urban transit operators are pursuing applying an unattended station operation system for their cost reduction. Therefore, an intelligent monitoring system is need for passenger's safety in railway. The paper proposes a vision based monitoring system and object detection algorithm for passenger's safety in railway platform. The proposed system automatically detects accident in platform and analyzes level of danger using image processing technology. The system uses stereo vision technology with multi-sensors for minimizing detection error in various railway platform conditions.
