Ikseon-Dong 166 is one of the traditional urban resident area developed during 1930's. The purpose of this research is to analyze the structural relationship between a conventional housing unit plans and modern block plans based on orthogonal geometry. To fully explore the selling point of the new urban development, the planner or real estate developer in private sector did not abandon or compromise the conventional house layouts, consists of single layer of rooms keeping the main room facing south. This study concludes the following factors connecting the urban and architectural plans. Oblong block plans following east-west direction did not allow the southern exposure of courtyard and main room, which was the absolute requirement for traditional house units, the longer side of block plan followed north-south direction as a result. Considering the possibility of rent, having entrance at the east or west side of individual site enables two separate household maintain their spatial privacy. In addition to the factors mentioned above, when the blocks are to be divided into individual addresses, north-south oblong block plans maintained the length to face the front road minimum while the southern exposure maximized. These factors explains why the private developers maintained their blocks elongated to north-south direction when the block plans laied out by public sectors which did not care that much of southern exposure show random orientation in the view point of solar exposure.

This study aims to clarify the transformation of urban spatial structure around old castle in cheong-ju city. The urban spatial structure is composed with road system, block division, and lot system with original cadastral map in 1913 and 2011 GIS. Transformation of road system is classified into control of road line, construction and extension of road. Construction of arterial road was divided into Nam-juro and Mang-sunro with 2 blocks and lot system was destoyed. Transformation of block has not been developed except 4 blocks. The 4 blocks were divided into east-west or north-south direction and became 8 blocks. Transformation of lot system is classified into maintained, subdivided, and destroyed lots in shape and size of lots. Maintained lots were found in large lot in size for public office and park. Subdivided lots were mainly represented with the existing main road, an active alleys, and so on. Destroyed lots by road construction and extension were showed in Nam-juro. Although all these transformations are used to enhance urban spatial structure. The old systems have remained around old castle in cheong-ju city.

The train control and monitoring system(TCMS) is an on board computer system in railway vehicles performing the control, supervisory and diagnostic functions of the complete train. This system replaces a lot of hardwired relays and minimizes the necessaries vehicle wiring thus increasing the reliability of the train. In this paper, we proposed a software design technique of TCMS using CASE tool (SAO+). The TCMS functions are implemented in software easily programmed, using a functional block, graphic programming language. We applied the compressor air module to a case study.

본 연구는 수원시 도심에 위치한 도시공원인 효원공원을 대상으로 여름철 대기온도 저감효과를 확인하고, 공원을 구성하는 서로 다른 피복유형별 특성을 파악하기 위하여 열 환경을 실측하고 분석하였다. 도시공원의 여름철 대기온도저감효과는 도심주거지 (매탄동) 대비 평균 4.4-4.5%로 통계적으로 유의하였고 (p< 0.001), 수원시의 외곽주거지 (상광교동) 보다는 약 0.8% 낮은 수준이었다. 도시공원 내 피복유형 (보도 블럭, 잔디 식재지, 소나무-잔디 식재지, 수목 차광지 및 혼합림 조경지)에 따른 열환경은 자연소재의 유형일수록 일평균기온, 일최고기온, 여름일수가 낮은 경향을 보였다. 그러나, 일최저기온 및 열대야일수는 피복유형에 따른 상관관계가 뚜렷하게 나타나지 않았다. 오후시간대 (13:00-15:00)에 혼합림 조경지, 수목 차광지, 소나무-잔디 식재지의 불쾌지수 (DI), 습구흑구온도 (WBGT) 및 열지수 (HI)의 평균값이 보도 블록과 잔디 식재지보다 낮아서 자연소재의 피복 유형의 열쾌적성이 양호한 것으로 나타났다. 그러나 각 지수에 대한 등급은 모든 피복 유형에서 '가장 높음' 또는 '주의' 단계로 동일하였다. 한편 오전 (06:00-08:00)에는 토지 피복유형별 열쾌적성에 차이가 없었다. 결론적으로 도시에서 열 환경을 개선하기 위하여는 초지, 숲 및 개방 지역의 토지 피복 유형을 증가하여야 한다.

Usually urban railways are built under ground thus the necessary condition of urban railroad, a linear-shaped track, causes a difficulty in enhancement of speed limits of urban rail. Also the underground construction of city railroad produces speed limit values reduced according to a speed code array, in case of speed decision according to the conventional block section division, thus onventionally it could not but apply speed limit values lower than actual safety speeds. In this study, The above two facts induced the author to study on a method to enhance speed limit values for CBTC within existing urban railroad sectors. Since it is possible to exchange data continuously and to control speeds in case of railroads based on CBTC, the author applied result values of speed limits, which were gained based on a railroad condition, a linear track, to the CBTC system without correction of the result values and then the author compared and analyzed, through simulation, the running times and the efficiencies of running energies between railway stations, between the existing fixed-block system and the CBTC system. As a result simulation, the improvement of speed and the deceleration distance of reduction confirmed that it was effective to reduce the time to travel between stations. A fixed block the set of constraints on the speed limit, he way the operation is optimized based CBTC speed limit by suggesting ways to reset the scheduled speed measures to improve were extracted.

Bongik-dong, Kwonnong-dong, Ikseon-dong and Nakwon-dong are areas around Donhwamun-ro in Seoul. These residential areas began to be developed collectively from the 1920s and the construction period was the fastest among hanok residences collectively formed in urban center. At that time, houses were developed with high density. In the 1920s, many medium-sized plots of less than 3,300m² were distributed around Donhwamun-ro. Private developers such as Jeong Se-kwon(Konyangsa), Shin Tae-jong, and Yoon Heung-rim, who were active at the time, purchased medium-sized plots. Developers sold out the land directly or after constructing Hanok on the divided plot and then selling them. This method of developing hanok residences by private developers in the 1920s have influenced on hanok residences which began to be developed after the 1930s. Currently, many urban Hanoks still remain in areas around Donhwamun-ro. The initial aspects of the hanok development in the 1920s could be grasped through blocks, plot division, alleys, row house Hanok etc around Donhwamun-ro.
