This article deals with international space law for the environmental protection in outer space especially for space debris arising from space activities. After studying 1967 Outer Space Treaty, 1968 Rescue Agreement, 1972 Liability Convention, 1975 Registration Convention and 1979 Moon Agreement, we could find few provisions dealing with space environment in those treaties. During the earlier stages of the space age, which began in the late 1950s, the focus of international law makers was the establishment of the basic rules of space law governing the states' activities in outer space. Consequently the environmental issues and the risks that might arise from the generation of the space debris did not receive priority attention within the context of the development international space law. Although the phrases such as 'harmful contamination', 'harmful interference', 'disruption of the environment', 'adverse changes in the environment' and 'harmfully affecting' in relation to space environment were used in 1967 Outer Space Treaty and 1979 Moon Agreement, their true meaning was not definitely settled. Although 1972 Liability Convention deals with compensation, whether the space object covers space debris is unclear despite the case of Cosmos 954. In this respect international lawyers suggest the amendment of the space treaties and new space treaty covering the space environmental problems including the space debris. The resolutions, guidelines and draft convention are also studied to deal with space environment and space debris. In 1992 the General Assembly of the United Nations passed resolution 47/68 titled "Principles Relevant to the Use of Nuclear Power Sources in Outer Space" for the NPS use in outer space. The Inter-Agency Space Debris Coordination Committee; IADC) issued some guidelines for the space debris which were the basis of "the UN Space Debris Mitigation Guidelines" approved by COPUOS in its 527th meeting. In 1994 the 66th conference of ILA adopted "International Instrument on the Protection of the Environment from Damage Caused by Space Debris". Although those resolutions, guidelines and draft convention are not binding states, there are some provisions which have a fundamentally norm-creating character and softs laws.

The purpose of this study is to estimate the perception of elderly residents on the residential environment improving projects and suggest the political implications. The survey include questionnaires about the importance and the satisfaction level on the project maintenance factors. The results were statistically analyzed by Importance-Performance Analysis (IPA). As the result of the study, firstly, it shows that 'the possible overkill area' on the IPA action grid includes none of factors except 'landscape' which is very similar to mean of performance score. the result of analysis means that the project is very efficient. Secondly, the policy is necessary to improve 'pedestrian passage', 'public open space' and 'transportation environment'. Considering elderly residents especially 'pedestrian passage' and 'public open space' are in need of improvement immediately. In detail 'traffic facility', building 'urban park' and 'pedestrian passage', 'paving of pedestrian passage', 'children's playground' are in need of improvement as well. The results of analysis on elderly and non-elderly residents of Yonnam project may be important foundation for future strategies for improvement.

The performance of the retail industry in a country, which simultaneously reflects the demand for retail space, is significantly influenced by the macroeconomic environment of said country. However, in the case of Malaysia, studies regarding this issue are limited. Therefore, this paper aims to identify the macroeconomic determinants of the demand for retail space in shopping centers in Malaysia through the study of six variables: per capita income, private expenditure, inflation rate, interest rate, total population, and the number of tourists arrival. The nexus between these variables and the demand for retail space in shopping centers were examined by cointegration and causality tests, and regression analysis using quarterly data for the period 1993Q1 to 2016Q4. The results from bivariate cointegration tests indicate that inflation rate, interest rates, population size, and the number of tourists arrival have significant long-run relationships with the demand for retail space of Malaysian shopping centers. Meanwhile, the Granger causality tests show that only population size can cause the demand for shopping centers' retail space. Finally, the results from the regression analysis revealed that income per capita, private expenditure, interest rates, and population are the variables that significantly influence the demand for the retail space of the Malaysian shopping centers.

The organic material is one of the most popular material for the satellites and the spacecrafts in order to perform the thermal management, and to protect direct exposure from the space environment. The present paper observes material property changes of organic material under the space environment by using ground facilities. One of the representative organic thermal management material of satellites, 2 mil ITO(Indium Tin Oxide) coated aluminized KAPTON was selected for experiments. In order to investigate the single parametric effect of protons in space environment, MC-50 cyclotron system in KIRAMS(Korea Institute of Radiological and Medical Science) was utilized for the ion beam irradiation of protons and ion beam dose was set to the Very Large August 1972 EVENT model, the highest protons occurrence near the earth orbit in history. The energy of ion beam is fixed to 30MeV(mesa electron volt), observed average energy, and the equivalent irradiance time conditions were set to 1-year, 3-year, 5-year and 10-year exposure in space. The procedure of analyses includes the measurement of the ultimate tensile strength for the assessment of quantitative degradation in material properties, and the imaging analyses of crystalline transformation and damages on the exposed surface by FE-SEM(Field Emission Scanning Electron Spectroscopy) etc.

Korea Astronomy and Space science Institute (KASI) partnered with the Australian National University (ANU) to develop the adaptive optics (AO) system at the Geochang observatory with a 100 cm optical telescope for multiple applications, including space geodesy, space situational awareness and Korean space missions. The AO system is designed to get high resolution images of space objects with lower magnitude than 10 by using themselves as a natural guide star, and achieve a Strehl ratio larger than 20% in the environment of good seeing with a fried parameter of 12-15 cm. It will provide the imaging of space objects up to 1,000 km as well as its information including size, shape and orientation to improve its orbit prediction precision for collision avoidance between active satellites and space debris. In this paper, we address not only the design of AO system, but also analyze the images of stellar objects. It is also demonstrated that the AO System is achievable to a near diffraction limited full width at half maximum (FWHM) by analyzing stellar images.

In order to create future-oriented special school facilities with a high-quality educational environment in response to various changes and demands of the times, it is necessary to break away from the existing uniform and formal framework to find appropriate special school space. This study was a basic research to construct an active detailed model of new and creative educational space that reflects the changes of future society and educational direction. In this study, we proposed a criteria based on case studies and expert advice, deviating away from the limitations and problems that existing special schools' educational space had. The direction of plan was presented based on the compilation of expert consultation and analysis of best practice facility survey across the nation. Based on the results of this study, it is intended to maximize the effectiveness of educational policies in the long term by preparing a specific facility model for the establishment of special school planning standards.

This study explored what impacts can be brought to students, teachers, schools, and community by the improvement of physical environment of school spaces. For the purpose, we studied 5 schools (2 elementary and 3 middle schools) who took part in the Happy School Project funded by the Ministry of Culture, Sports, and Tourism in 2008. Ten series of Focus Group Interviews were carried out with a sample of 28 students and 20 teachers who experienced both before and after the school renovation project. The analysis of the interview data revealed that although the project was concerned with a part of school space such as restroom or reading room, it could bring multiple effects such as following: First, the students addressed that they felt "good" about school environment, which led them to feel good about their "schools." This change was found out to bring about more positive attitudes towards a school in general, public manners, peer relationships, emotional well-being, and learning. Second, the teachers became to value more their principals' leadership, being more satisfied with their work environment and more concerned about management of school facilities, and happier with students in terms of teaching and guidance than before. Third, all the 5 schools seem to go through a noticeable change in terms of a school climate and ethos in a more positive and harmonious way. Finally, 'spread', 'promotion', and 'openness' effects were discussed with regard to the relationships between the schools and local community.

The purpose of this study was to compare student's satisfaction with school food service environment to improve the quality of middle school meal service. A survey was conducted of 680 students (boys 246, girls 433) from 6 middle schools providing school meals from October to November 2007. The questionnaires were directly distributed to the subjects for comparison of satisfaction of school meals depending on the eating place. As for the quantity of food, classroom group (3.40) expressed significantly higher satisfaction than cafeteria group (3.16, P < 0.01), but as for the satisfaction on hygiene, classroom group (2.76) showed significantly lower satisfaction than cafeteria group (3.03, P < 0.01). About the satisfaction of school meal environment, classroom group showed more satisfaction on distribution time, eating place, eating atmosphere (P < 0.001). The classroom group showed higher satisfaction than cafeteria group in cases of quantity, diversity of types of soup, dessert, and the cost of school meal. To improve eating place and hygiene of school meal, sufficient cafeteria space and pleasant environment is needed to be established.

Since the introduction of the new Variation Type school, few studies have focused on students' adaptation to the changes in their learning environments at school. This paper is based on the Stage-Environment Fit theory, which asserts that a successful school life(in terms of motivation to learn) is ensured only when the school environment meets the social and emotional needs of students. Focusing on the third-grade student's adaptation to a new Variation Type school during their middle school period, the following conclusions were drawn. First, the transition to a new Variation Type school during middle school is much more difficult than adjusting to a new Variatio Type school upon admission to middle school. Second, this difficulty in adaptation is caused by socio-emotional dissatisfaction in adolescent students, for whom deconstruction of previous friendships can hinder motivation to learn. Third, third-grade students who experienced stress due to spatial changes tended to have a negative attitude towards the new Variation Type itself as they feel more tired from failing to use the space properly. Fourth, to transition successfully to a new Variation Type school, socio-emotional problems must be solved through the reduction of scale of the homebase, and the provision of various choices increasing the number of homebase.
