Early in the communist era, many cities in modern China experienced a special period of passive industrialization during which the construction of urban spaces laid the spatial urban foundation. During this period, the city construction was carried out rapidly under the administrative intervention of the government. The passive industrialization caused by taking economic construction as the center made the city construction deviate from the correct track and resulted in a variety of problems. Focusing on ecological space change, this paper selects Zhengzhou as an example of many similar cities in China, and analyzes the impact of passive industrialization on urban ecological spaces from the perspectives of city scale, city layout and city construction management system. The analysis results reveal that the construction of urban ecological space under the influence of passive industrialization induced a lagging characteristic, led to insufficient integrity of urban ecological space, and placed great pressure on the urban environment. Finally, the paper puts forward some methods to optimize the urban ecological space.

Purpose: The principal objective of this study was to assess the relationships of depression, fatigue, BMI, and health locus of control between urban and rural female middle school students. Methods: The study subjects included 377 girls in randomly-sampled middle schools in urban and rural provinces. The data were collected via self-recorded questionnaires from April 21.- to May 2. 2008, and analyzed using the SPSS Win 12.0 program. Results; 1) The mean score of depression was $10.22{\pm}5.72$ (urban), $10.81{\pm}4.92$ (rural). 2) The mean fatigue score was $50.43{\pm}1.57$ (urban), $51.90{\pm}9.70$ (rural). 3) BMI was classified into 3 groups: leptosomic, normal weight, and obesity groups. The mean BMI score was $18.73{\pm}2.05$ (Seoul), and $20.31{\pm}3.26$ (provincial). 4) The internal locus of control was higher than the external locus of control (urban). 5) Fatigue was correlated with depression (r=.512, p=.000) in both areas. The health locus of control was correlated with Fatigue (r=.153, p=.042) in province. Conclusion: An effective program to reduce the levels of fatigue and depression for middle school girls and to maintain normal weight is required. In particular, the high-risk depression group can be managed through community mental health care center deep interviews, and close observation.

As de-schooling students (students who leave schools) have been produced and increased in middle and high schools every year since 1990s, urban alternative schools have founded with Seoul as the center. The objects of such urban alternative schools are de-schooling teenagers, and their educational goal is to make the students to discover their own values and grow as members of the community by accomplishing their healing and growth. Most of students in alternative schools have excessive self-centered feeling than ordinary people, and since they don't have exchanges with others, they have to receive holistic healing along with education. Here, 'healing' is a method of approaching to health through environmental, psychological, social and cultural supports unlike 'treatment' used for medical means. Therefore, holistic healing for alternative schools' students has to accomplish self-knowledge, self-control, and self-healing without repulsion through spaces of healing environments instead of heavy-handed exchanges. This study has integrated a theory of Max $L{\ddot{u}}scher$ who suggested a psychological healing theory in terms of internal character and a theory of Rudolf Steiner who suggested it in terms of practical and holistic sense and analyzed Sungmisan School, one of urban alternative schools in Seoul through the integrated theory. The analysis of the integrated theory are intended to emphasize the importance of healing environments and suggest methods in creating healing environments for urban alternative schools in the future.

도시농업의 기술 중 하나인 수경재배 농법은 공간의 물리적 제약이 다른 도시농업 활동에 비해 적고 재배환경을 어디든지 쉽게 구축할 수 있다는 장점이 있어 그 활용 가치가 높지만, 기존의 연구 대부분이 기술 개발에 초점 맞추어져 있어 도시민의 여가 문화적 가치를 내포하는 도시농업의 문화적 활용성 측면에서 연구가 부족하였다. 따라서, 본 연구는 수경재배를 활용한 도시농업 활동에서 학내 구성원이 인식하는 참여제약요인을 파악하고 도시농업 여가 향유의 관점에서 참여 의사결정에 영향을 미치는 변수 간 구조적 관계를 파악하였다. 근거이론과 선행연구 고찰을 통하여 수경재배 도시농업의 참여제약요인을 3가지 측면으로 나누고, 서울대학교 구성원을 대상으로 설문 조사를 수행한 후 R software를 활용하여 요인분석 및 구조모델에 대한 평가를 시행하였다. 그 결과로 첫째, 수경재배를 활용한 도시농업 활동에서의 참여제약요인은 크게 내재적 요인, 대인적 요인, 구조적 요인으로 나뉘었다. 둘째, 가설 모형 검증 결과로 대인적 제약이 참여자의 참여의지와 기대행동에 유의한 영향을 미치는 것으로 나타났다. 본 연구는 옥상이라는 도시공간에서 행해진 수경재배 도시농업에 대한 학내 구성원의 다원적 가치 인식을 파악하였으며, 연구 결과를 활용하여 도시공간이나 옥상에서 이루어지는 수경재배 도시농업 활동에 더 적극적 참여를 유도하는 전략에 근거를 제시할 수 있다.

Background and objective: The vitalization of urban agriculture has increased various forms of experience-based education using school gardens, which raised the importance of school gardens in terms of value as well as the need to develop an implementation system for education-based agricultural experience service using school gardens. Thus, we reset the evaluation indicators from the previous study to establish objective evaluation indicators that enable quantitative comparison of school garden education services. Methods: Analytic hierarchy process (AHP) and direct question (DQ) surveys were conducted on 20 experts from October 12 to 19, 2020 after establishing the purpose and subjects of evaluation, and then the weights were calculated using the Expert Choice 2010 program. Results: First, we analyzed the problems of the previous indicators by categorizing the performance indicators and comparing and verifying them with six requirements of valuation. Then, we added 'welfare values' and established sub-indicators accordingly. The importance of value indicator in AHP was in the order of education values (0.544), health values (0.182), welfare values (0.164), environmental values (0.062), and economic values (0.049). The importance of environmental and economic values was relatively low, less than 0.1. The importance of sub-indicators was highest in cultivating character (0.144), followed by enhancing ecological sensitivity (0.141) > promoting mental health (0.134) > cultivating agricultural literacy (0.120) > improving social skills (0.104). And mitigating climate change in environmental values was lowest (0.009). Increase in income was the lowest (0.036). This can be regarded as the expression of change to increase the educational effect based on collective life and the connotative meaning of 'school'. In the case of DQ, the AHP weight and order were the same, but the environmental and economic values were relatively low, and the result was different from AHP weight. For sub-indicators, the importance in DQ was highest in promoting mental health (0.136), followed by promoting physical health (0.085), ]cultivating character (0.082), social integration (0.072), and enhancing ecological sensitivity (0.071). After reviewing related experts, we came up with 5 evaluation indicators and 16 sub-indicators for school garden education service, which are objective evaluation indicators that enable quantitative comparison. Conclusion: In the future, we will validate the socioeconomic values of school garden education services and contribute to revitalizing school gardens by establishing policy alternatives for effective operation and management of school gardens.

The purpose of this paper is to propose a simple analysis method of axial deformation of base-isolation rubber bearings in a building subjected to earthquake loading and present its applicability to the analysis of the bound of the aspect ratio of base-isolated buildings. The base shear coefficient is introduced as a key parameter for the bound analysis. The bound of the aspect ratio of base-isolated buildings is analyzed based on the relationship of the following four quantities; (i) ultimate state of the tensile stress of rubber bearings based on a proposed simple recursive analysis for seismic loading, (ii) ultimate state of drift of the base-isolation story for seismic loading, (iii) ultimate state of the axial compressive stress of rubber bearings under dead loads, (iv) prediction of the overturning moment at the base for seismic loading. In particular, a new recursive analysis method of axial deformation of rubber bearings is presented taking into account the nonlinear tensile behavior of rubber bearings and it is shown that the relaxation of the constraint on the ultimate state of the tensile stress of rubber bearings increases the limiting aspect ratio.

Remote sensing data is collected and analyzed to enhance understanding of the terrestrial surface. Since Landsat satellite was launched in 1972, many researches using multispectral data has been achieved. Recently, with the availability of airborne and satellite hyperspectral data, the study on hyperspectral data are being increased. It is known that as the number of spectral bands of high-spectral resolution data increases, the ability to detect more detailed cases should also increase, and the classification accuracy should increase as well. In this paper, we classified the hyperspectral and multispectral data and tested the classification accuracy. The MASTER(MODIS/ASTER Airborne Simulator, 50channels, 0.4~13$\mu$m) and Landsat TM(7channels) imagery including Yeong-Gwang area were used and we adjusted the classification items in several cases and tested their classification accuracy through statistical comparison. As a result of this study, it is shown that hyperspectral data offer more information than multispectral data.
