조선후기 경기지역은 한강수운을 비롯한 'X'자형 간선도로망의 중심에 입지하여 재 화와 정보, 기술의 유입이 他道에 비해 빠른 곳일 뿐 아니라, 행정. 상업.위수기능이 집중 하여 도회의 발전가능성이 많은 곳이었다. 조선후기의 도회는 고급행정중심지를 제외하면 대개 3,000-5,000정도의 인구를 보유한 작은 규모로 도회거주민은 관리, 상인, 장인, 노비 등 非農民層이 주류를 이루었다. 경기도 내에 비농업적인 도시기능을 수행한 곳은 한성과 개성 을 비롯해 모두 52곳이다. 이들 중 인구 3,000명 이상의 도회로 성장한 곳은 29곳인데 대부 분 조선시대의 간선도로망인 'X'자형 도로망중 서북-동남축을 따라 분포하였다. 경기도의 도회를 중심지의 인구규모와 도회기능의 소유 정도에 따라 계층화하면 6개의 등급으로 나눌 수 있다. 각 등급별 도회상황을 살펴 본 결과 1등급에서 4등급까지는 도회화의 정도가 차이 가 남을 알 수 있지만 4등급에서 6등급까지는 전체전인 도회의 모습에 있어서 그다지 큰 차 이가 나타나지는 않음을 알 수 있다.

This study aims at the development on the wood-frame house construction method in hilly areas. To obey the trend of public opinion to prohibit the troublesome development on a large scale in preparing housing sites, the small housing site development in hilly areas is on the rise and consequently wood-frame house which harmonized natural topography, geographical feature and environment in hilly areas is needed. The main contents are how to make housing sites, how to make roads, how to make pedestrian ways and surroundings of water to run downhill, how to locate house, how to make between road and house, how to view inner and outer and how to make retaining wall on the wood-frame house construction method in hilly areas.

Recently the necessity of road data is still being increased in industrial society, so there are many repairing and new constructions of roads at many areas. According to the development of government, city and region, the update and acquisition of road data for GIS (Geographical Information System) is very necessary. In this study, the fusion method with range data(3D Ground Coordinate System Data) and Intensity data in stand alone LiDAR data is used for road extraction and then digital image processing method is applicable. Up to date Intensity data of LiDAR is being studied. This study shows the possibility method for road extraction using Intensity data. Intensity and Range data are acquired at the same time. Therefore LiDAR does not have problems of multi-sensor data fusion method. Also the advantage of intensity data is already geocoded, same scale of real world and can make ortho-photo. Lastly, analysis of quantitative and quality is showed with extracted road image which compare with I: 1,000 digital map.

The existing leg-rest for transmission line construction was established on the ground as a structure. As a result of that, it caused some problems such as, a tremendous forest damage, excessive construction costs and the long time of construction period. In order to solve these problems, we suggest the protective net for an air installation. It is a new method of construction which has a dielectric strength with a light-weight and high-strength. And it's not influenced by a geographical feature. This excellent method doesn't affect a forest and can reduce tremendously the construction cost and period.

Recently the development of GIS and spatial information technology is used to construct very detail forest information. In addition, in order to classify forest characteristic, the geographical characteristic information of forest could be very useful for the forest classification, In this study sampling points were arranged to clarify the difference between the orm area and the land forest area. Also, forest feature pattern could be discriminated by using satellite images and SML. This study result should be constructed to efficiency forest management in especially forest area in Jeju Island

The purpose of this study was to investigate the middle-aged housewive's background characteristics influencing on the preference of elderly housing, depending on four aging-situations. The characteristics of the elderly housing dealt in thes study were geographical location. specially planned feature for the elderly, house type, the size of housing, housemate, the distance from the living quarter of their children, and whether they want to live in the rental house. The subject were 526 middle-aged housewives from middle-income householde living in the capital area. Questionnaires were sent through mail to the householde which tesponded positively on the information brochure about this study sent before. The characteristics of the elderly housing which perferred to was influenced by their age and socio-economic status, such as schooling, job, income, and the size of housing. This result suggests that it must be considered to develop various types of the elderly housing depending on socio-economic status.

To classify seafloor sediments using a probabilistic neural network (PNN), the frequency-dependent characteristics of broadband acoustic scattering, which make it possible to qualitatively categorize seabed type, were collected from three different geographical areas in Korea. The echo data samples from three types of seafloor sediment were measured using a chirp sonar system operating over a frequency range of 20-220 kHz. The spectrum amplitudes for frequency responses of 35-75 kHz were fed into the PNN as input feature parameters. The PNN algorithm could successfully identify three seabed types: mud, mud/shell and concrete sediments. The percentage probabilities of the three seabed types being correctly classified were 86% for mud, 66% for mud/shell and 72% for concrete sediment.

As car industry takes the DMB, geographical feature information and Internet service recently, the need of an electricity energy is the trend to increase. But existing 12V car electricity system is difficult to be satisfied rapidly increasing electricity need. A relation component company is adding the spur at a high electricity system development. In this paper we accomplished the hi-directional DC-DC Converter for high electricity system composed 42V configuration device. Through a simulation experiment, We looked into the control method and the operation characteristic of the circuit, We accomplished the comparison analysis for fit topoloy selection.

Korea is closed to China in the geographical position and is related to China as two countries have developed similar culture, art, and social systems. Architecture is a kind of culture and has advanced in the wooden architecture with a considerable change. The study investigated a phylogenetic relationship between two countries based on characteristics of architectural universality. With comparison and analysis on the common feature and difference of the beam and structure in the wooden architecture from the Koryo and Zhejiang Province(China), the systemicity of the wooden architecture was examined. The beam is a part of timber which is consist of the wooden structure frame and also a crucial subject to understand a development process of the wooden architecture.

Transverse stress and longitudinal crack which are induced by temperature difference in box-girder sections and slab of which box-girder is composed have an important effect on endurance and economical efficiency of bridges. The study on longitudinal behavior of bridges which are subject to thermal load is reflected on the design of bridges. But, the study on transverse behavior of bridges has been performed just recently in foreign countries of finding the cause of longitudinal crack and in Korea, has not been tried in spite of large temperature variance due to geographical condition. This study examines temperature distribution feature in box-girder sections and bridge behavior due to thermal load, with measuring temperature distribution and stress of PSC box-girder bridge which is being constructed actually, and investigates appropriateness of design thermal load of highway bridge design code.
