In the current Korean seismic design guide, the site classification and the corresponding site coefficients were determined based on the UBC-1997 (Uniform Building Code). In order to develop the current site classification system, it is important to compare the local site conditions in Korea to other countries which have similar seismic design guides. In the eastern United States, New York City(40degrees 45minutes north latitude, 73degrees 59minutes west longitude) suggested that current design guidelines are unsuitable to shallow bedrock depth sites. So the 3-parameter methods are performed for new criteria in New York City. In this study, site response analyses were performed at 181 study sites using one-dimensional equivalent linear to evaluate the site-specific earthquake ground motions at inland areas in the Korean peninsula and reclassify the results according to similar ground motions using the 3-parameter methods. It is effective that multi-parameter methods for Korean site characteristics in comparison with single parameter method.

The purpose of this study is to construct a database for landscape ecological planning with evaluation and analysis of structure of biotope of city center area for the preservation of species and biotope examining Jung-gu district of Daegu Metropolitan City which is the most extremely and rapidly urbanizing area. The assumption of this study is that the biotope structure of a city center area would be different from the other city area. The results of this study were as follows. 1) The results of the biotope type classification is that there were 11 biotope type groups and 41 detailed biotopes. 2) The primary evaluation is the process for grading general value of classified biotope types, and the result of primary evaluation is that there were 5 biotope types that were greater than third grade besides the biotope type of artificial riverbank with abundant green high water level land. The first grade of biotope type have not appeared in this area, however the fifth grade of biotope type have appeared total of 19 biotope types with the biotope type of the general shopping area with scarce green fields. 3) The secondary evaluation is the process for searching biotopes which are special value, and the result of secondary evaluation is that there were 2 biotopes for la, 7 biotopes for 1b, 2 biotopes for 2a, 1 biotope for 2b and there was no biotope for 2c, and for example, la is the large area that has many magor biotope site in terms of the living space. 4) Finally. scientific method for biotope type classification, the derailed investigation plan of high value biotope and the improvement plan based on the biotope map of city center area must be continued.

The research focused on the landscape of mountains and hills drawn in a landscape picture. The purpose of the research is to classify patterns of landscape drawning in landscape pictures and to clarify the characteristics of the pattern by a quantitative index. We selected 21 landscape pictures to understand the Landscape Setting Here(LSH) and Landscape Setting These(LST). We investigated size quantitative indices using 1 landscape picture. The index is a follow: altitude, Visual Distance, Angles, Angle of Appearance Size, Inclination, and Angle of Incidence. The following results were obtained by using this data. 1) It has been understood that we offer an important city view because the LSH of this research can establish understanding of the city structure. 2) We dividing 3 patterns by the LST space drawn in the landscape picture. 3 patterns are Ferry point, Beauty point, an Signal-fire point. 3) We clarified the landscape characteristics of each pattern and the characteristics between patterns by using the index according to this pattern. 4) We understood the problem concerning the Seoul city landscape examining the pattern of this research with the ordinance of Seoul city. It is necessary to standardized a system of pattern classification utilized in landscape pictures to establish a universally interpreted detailed quantitative index, which can be applied to research.

The city means not only a geographical area as a role of the spatial boundary, but also a socio-economic place to communicate with each part. It requires various functions to get the income and activities. But city has a limitation of a available land to provide the required function and a sufficient space to supply the activity. Therefore, the development trend of city has not been to spread to the horizontal area any more and considered the vertical area. In addition, various functions put into a massive building because many people want to solve the daily requirements without spending time and cost. In this paper, it aimed at classifying the mixed-use building into function, circulation, relation between the public and private space and the building shape to provide the design information according to the development constraints such as land area, functional limitation, accessibility, etc. The classification of the mixed-use buildings is divided into four areas. The data are collected with foreign countries in Japan, Europe and US.

본 연구는 LANDSAT TM영상을 이용하여 도농중심도시인 김제시의 토지이용변화를 분석하고 미래 변화예측을 시도한 것이다. 감독분류 시 새로운 시도로 훈련영역 선정 시 HSB(Hue, Saturation, Brightness) 변환영상을 이용함으로써 약 5% 이상의 분류정확도 향상을 가져왔다. 분류결과와 해당지역의 구역 별 인구, DEM, 도로망, 수계 등 GIS데이터를 고려하여 셀룰라오토마타 알고리즘을 발전시킨 Markov Chain 기법으로 토지이용변화예측을 실시하였다. 토지변화비율을 비교 분석한 결과 지형적인 특성이 토지이용의 변화에 가장 크게 영향을 미치는 것으로 판단되었다. 또한 2030년 후의 토지이용변화 예측 결과 김제시 전체에서 산악지의 21.67%가 농경지로 13.11%는 시가지로 변화될 것으로 예측되었다. 주된 변화는 도심 중심부에 위치한 규모가 작은 산악지인 것으로 예측 되었다. 연구결과 미래의 토지이용변화를 예측함으로써 식량자원의 확보를 위한 도농도시의 토지이용계획에 도움이 될 것으로 확신한다.

본 연구에서는 u-Eco City 건설을 위한 u-City 기술 연구의 첫걸음으로서 기반시설 관점에서 u-City기술을 분류하고자 한다. 이는 u-City를 구현할 때 기반시설에 u-City기술을 접목함으로써 u-City서비스를 실현할 수 있기 때문에 의미가 있다. 즉, "유비쿼터스 도시건설 등에 관한 법률"에서 언급하고 있는 u-기반시설의 개념을 도입하여 기술을 분류함으로써 서비스-기술-기반시설의 연계성을 명확하게 파악할 수 있다. 본 연구에서 제시하고자하는 u-City 기술의 분류는 u-City기술의 범위를 정하고, 추후 기술개발의 전략적 목표 설정 및 기술전략 수립의 기초자료로써 활용될 수 있으리라 기대된다.

KUbiquitous city(U-City) is a recent trend in urban planning and management across the globe. Currently, several typologies were developed and presented classifying U-City services, but validation research of these typologies are scarce. In this study, efforts were made to qualitatively validate the usability and practicality of a typology of u-city services. Using 228 U-City services identified in previous studies, classifying exercises were conducted against a typology. Three experts were involved in this expert heuristic exercise, against a most popularly used and comprehensive typology of U-City services. Findings indicates that the selected typology is high on comprehensive exhaustiveness, and empirical applicability while low on mutual exclusivity, simplicity and theoretical contribution. Implications for the typology improvement are suggested followed by limitations and directions for further research.

1. Objectives: This research was proposed to reinterpret "Soeumin Bumron(少陰人 泛論)"through development of Soeumin exterior disease in Sasang Constitutional Medicine(SCM). 2. Methods: We chronically compared the conceptions, symptoms, mechanisms and treatments of Soeumin exterior disease from "Donguisusebowon-GabObon(東醫壽世保元甲午本)"(DGO) to " "Donguisusebowon-ShinChukbon(東醫壽世保元辛丑本)"(DSC) 3. Results and Conclusions: (1) The classification standard of Soeumin exterior disease was different in DGO and DSC. (2) Soeumin exterior disease classified Taeyang Disease(太陽病), Yangmyoung Disease(陽明病) in DGO and Ulkwang-syndrome(鬱狂證), Mangyang-syndrome(亡陽證) in DSC. (3) Based on the changes of understanding about Soeumin exterior disease from DGO to DSC, we attempted to reinterpret "Soeumin Bumron(少陰人 泛論)" in view of DSC. In view of DSC, the classification standard of Soeumin exterior disease focused on Warm Yang Qi(陽煖之氣), Healthy energy(保命之主) of Soeumin.

본 연구에서는 국내 도시가스 인수량에 대한 예측 모델을 개발하였다. 국내의 도시가스 회사는 KOGAS에 차년도 수요를 예측하여 보고해야 하므로 도시가스 인수량 예측은 도시가스 회사에 중요한 사안이다. 도시가스 사용량에 영향을 미치는 요인은 용도구분에 따라 다소 상이하나, 인수량 데이터는 용도별 구분이 어렵기 때문에 특정 용도에 관계없이 영향을 주는 요인으로 외기온도를 고려하여 모델개발을 실시하였다.실험 및 검증은 JB주식회사의 2008년부터 2018년까지 총 11년 치 도시가스 인수량 데이터를 사용하였으며, 전통적인 시계열 분석 중 하나인 ARIMA(Auto-Regressive Integrated Moving Average)와 딥러닝 기법인 LSTM(Long Short-Term Memory)을 이용하여 각각 예측 모델을 구축하고 두 방법의 단점을 최소화하기 위하여 다양한 앙상블(Ensemble) 기법을 사용하였다. 본 연구에서 제안한 일별 예측의 오차율 절댓값 평균은 Ensemble LSTM 기준 0.48%, 월별 예측의 오차율 절댓값 평균은 2.46%, 1년 예측의 오차율 절댓값 평균은 5.24%임을 확인하였다.
