본 연구는 도시확장이 원도심 쇠퇴의 원인으로 작용할 수 있을 것으로 가정하고, 그 가능성을 공간구문론(Space Syntax) 방법론으로 검토하고자 제주읍성 일대의 원도심을 대상으로 도시공간구조 분석을 수행하였다. 도시공간구조에 관한 종단적 분석의 시점은 일제강점기부터 현재 사이에 1914년, 1972년, 1982년, 1996년, 그리고 2021년 현재의 5개 시점으로 설정하였다. 도시공간구조 분석은 공간구문론의 ASA(Angular Segment Analysis)를 활용하였다. 분석결과, 제주시 동지역의 도시구조는 1914년에서 2021년 사이에 큰 변화를 겪어왔다. 도심은 단일핵 구조에서 다핵 구조로 변화하였으며, 원도심이 위치한 구제주 지역은 지리적으로 바다와 접하여, 도시확장이 한라산 자락의 남측으로 편중되어 도시중심부의 위치도 점차 남쪽으로 이동하였다. 이에 따라 제주시 원도심은 도시공간구조의 역동성에 의하여 도시중심부의 중심지에서 주변지역의 하나로 전락하였다. 이와 같이, 도시확장에 의한 도시공간구조 변화 과정에서 원도심의 도시중심부 이탈이 이루어졌다는 점에서, 원도심 쇠퇴의 한 요인으로서 도시확장의 가능성을 확인할 수 있었다.

In order to make reliable earthquake-resistant design of civil engineering structures, one of the most important considerations in a region with high seismicity is to pay attention to the local soil condition of regions. It is aimed in the current study at specifying dynamic soil characteristics of Kirikkale city center conducting the 1-D equivalent linear and non-linear site response analyses. Due to high vulnerability and seismicity of the city center of Kirikkale surrounded by active many faults, such as the North Anatolian Fault (NAF), the city of Kirikkale is classified as highly earthquake-prone city. The first effort to determine critical site response parameter is to perform the seismic hazard analyses of the region through the earthquake record catalogues. The moment magnitude of the city center is obtained as $M_w=7.0$ according to the recorded probability of exceedance of 10% in the last 50 years. Using the data from site tests, the 1-D equivalent linear (EL) and nonlinear site response analyses (NL) are performed with respect to the shear modulus reduction and damping ratio models proposed in literature. The important engineering parameters of the amplification ratio, predominant site period, peak ground acceleration (PGA) and spectral acceleration values are predicted. Except for the periods between the period of T=0.2-1.0 s, the results from the NL are obtained to be similar to the EL results. Lower spectral acceleration values are estimated in the locations of the city where the higher amplification ratio is attained or vice-versa. Construction of high-rise buildings with modal periods higher than T=1.0 s are obtained to be suitable for the city of Kirikkale. The buildings at the city center are recommended to be assessed with street survey rapid structural evaluation methods so as to mitigate seismic damages. The obtained contour maps in this study are estimated to be effective for visually characterizing the city in terms of the considered parameters.

In the present circumstance of exploring measures for sustainable development, finding and using planning elements of historical city is getting important as a urban planning tool. Thus this study aims to examine the characters of Korean traditional urban form through three periods, Josun, modern and contemporary eras. Three urban centers representing different characteristics were selected; historical center based on 14th century's traditional planning, modern period urban center, which is related with development of railway, and contemporary urban center of late 20th century. Analyse of urban tissue, composed with form and scale of street network, blocks and plots, shows that each urban center of Seoul has certain common attributes in terms of morphology in spite of the difference of formation and development period. However this historical urban forms are rarely applicated in the current urban planning, such as new-town planning or district unit plan. This shows the necessity of modification of urban regulation for preserving the identity of our city and pursuing sustainable development.

We had prepared MLV liposome with Hibiscus Esculentus Ext.(HEE) which have fluorescent light in order to evaluate its percutaneous absorption about hairless rat skin. Then we investigated particle size of MLV using confocal laser scanning microscope(CLSM) and transmission electron microscope(TEM), respectively. Stability of MLV liposome and penetration of MLV liposome to hairless rat skin was measured by CLSM. As a result of experiments, MLV was globular shape and the rage of particle size was 0.3-0.5$\mu\textrm{m}$ mostly. Cream-type MLV had high stability comparatively. When we treated with MLV to rat skin, skin penetration was enhanced, especially, the optimum concentration of MLV on penetration to rat skin was 10%. Optimum penetration time was 6hr-12hr. And MLV-type HEE was more effective on percutaneous absorption than HEE-cream or liposome-type HEE.

The recent change of social environment has influence on the configuration of space for the social welfare center. And so the relation of space and function required the change of spatial configuration. The social welfare center fills the role of family welfare, domiciliary care, community organization etc. In such sence, this study explore the conditions of spatial configuration for the domiciliary and community care unit of social welfare centers in small city. For this study, it was investigated the space role and funtion, the service program, the usage characteristics, the room satisfaction of social workers. In sum, the useful data were collected, analyzed, and colligated by case study. It could be used in the design criteria of domiciliary care unit for the social welfare center in small city.

Aging populations and the increasing mental health issues among them have set a new challenge for the international community, governments, and people. Given this, society's role is very important, and involving the local community in resolving the problems can play a pivotal role. The current study presented the systematic review of the financing mechanism and cost-effectiveness of the "social prescribing" (SP) project in the United Kingdom and how SP can be adapted for other settings. The data showed comparatively low running costs and the overall effectiveness of SP projects. The running cost of SP projects varied between £54,525 and £1.1 million. The cost-effectiveness of the projects reported as 12% and the return of investment was about 50% depending on the type of analysis and the activities implemented. This type of intervention can be one of the options that support solving the issues of aging populations and their accompanying mental disorders.

The purpose of this study is to know the characteristics of the ancient city through the basic composition of Jericho city. But there are little documents in the ruins of Jericho, and so there are the limit to understand the basic characteristic of the ancient city. And so this study is going to know the symbolic meaning of the ancient city of the Jericho city, through the transcriptions remains. Producing the concept that Jericho is the old city in the world, this study is significant that utilizing with the basic document of helping to understand the basic composition and characteristic in the ancient city. Also because the bible documents of Jericho is explained the city in the bronze age, this study sets bounds to BC 15C, and to know the symbolic system in Jericho. In the christian transcriptions, it is represented the Jericho city BC 15C. Jericho city here is described the type of the labyrinth is composing of the city in the center and surrounding by the walls. The circular type of the labyrinth city has symbol of the 'protect' having the magic power against the opposite party. Also the walls of labyrinth are the boundary territory of 'abstract conception' to round seven times. The center in the shape of Jericho is 'closing field' against circumferences, and this is different from the labyrinth on the floor in the medieval Cathedral is symbolized 'opening field'

The purpose of this study was to investigate the space feature of day care center in Taegu city. This study was conducted by means of the observation on the equipments, the actual measurement of space of day care center and environment, and the questionnaire survey by the chief of day care center. The samples for analysis were 20 day care center located in Taegu city. The Major findings were as follows; 1) The chief's satisfaction of the facilities of day care center was generally low. 2) The door design, the lighting conditions, and the toilet need to be improved. 3) According to observation on the equipment, it was suggested that the environment of day care center was not desireable.
