There is a rental housing policy in Korea to support low income citizen. However, the living condition of tenants through this rental program is not work for improving, unlike the initial purpose of providing rental housings. Rental housings, which were planned to improve the residential welfare and enhance self-reliance ability of low income groups and the elderly. It's not effective any more in terms of policy purpose. To solve this problem, plans are needed to support for the construction by Farm-Housing(FH) so that the residents of can support their self-reliance by promoting creating jobs and cooperation. This paper analyze and propose some solution in terms of legal system, financing and streamlining of planing process and permission to support FH program. The paper focus purpose to help identify a new area through such proposals and retain a power of leading technology by bridging the gap between the realistic aspect and ideal aspect.

본 연구는 한국청소년정책연구원에서 제공하는 한국아동 청소년 패널조사(Korean Children and Youth Panel Survey) 3차년도(2012) 자료를 이용하여, 중학교 3학년 2,040명의 자아존중감이 삶의 만족도에 미치는 영향을 분석하였다. 생태학적 관점에서 삶의 만족도에 대한 영향요인으로 환경특성(부모친밀도, 친구친밀도, 교사친밀도, 학습적응도)과 개인특성을 고려하였다. 개인특성으로서 자아존중감을 긍정적 자아와 부정적 자아에 대한 평가라는 별개의 두 차원으로 구분하였을 때, 삶의 만족도에 대한 영향요인으로서 두 평가 수준의 상호작용 효과가 존재했다. 즉 부정적 자아평가가 삶의 만족도에 미치는 영향은 긍정적 자아평가 수준에 따라 달랐는데, 긍정적 자아를 높이 평가할수록 부정적 자아가 삶의 만족도에 미치는 음(-)의 영향은 감소했다. 또한 부정적 자아평가 수준이 낮을수록 삶의 만족도가 높았지만, 긍정적 자아평가가 상대적으로 낮은 수준에서는 삶의 만족도가 높지 않았다. 이러한 결과는 청소년의 부정적 자아 형성의 문제를 해결하는 것이 긍정적 자아 형성으로 이어지지 않을 수 있으며, 삶의 만족도를 증진시키기 위해서는 부정적 자아 형성의 문제해결을 넘어 긍정적 자아 형성을 위한 방안과 정책들이 모색되어야 한다는 것을 제시한다.

The global process of transition from industrial to information society, as well as socio-economic changes taking place in Ukraine, require significant changes in many areas of state activity. It is especially connected with the reforms in the sphere of education. Today, national programs provide for the development of education on the basis of new progressive concepts, the introduction of the educational process of new pedagogical technologies and scientific achievements, the creation of a new system of information education, entrance of Ukaine into the transcontinental computer information system. Information technologies are qualitatively changing the key resources of development: this is no longer a space with fixed production, but primarily mobile finance and intelligence. They have a direct impact on the formation of personal growth, professional content and self-organization, emotional and psychological maturity and consciousness, and so on. One of the main factors in ensuring the stability and social education of the country's citizens is the culture of security, the formation and development of which is an urgent problem today. Comprehensive and systematic development of security culture will significantly increase the readiness of the population, the level of environmental, labor and patriotic education, reduce human losses, material damage from emergencies. Ecological education can be carried out more successfully only gradually and in accordance with the socio-psychological periods of one's development: kindergarten - school - college - university. The creation of such a system of environmental education should be enshrined as the basis of state environmental policy as a constitutional norm with the usage of information technology. Graduates of universities, who are the future of our country, after mastering the skills of basic environmental education must have a high level of environmental culture, which is, in turn, part of general human culture, and investigate environmental issues from the standpoint of their profession. It is known that with the help of environmental education the collective intelligence of society is formed, which can predict human activities and processes occurring in nature, and in some way to help with the elimination of crises. It is through environmental education that another system of human values is being formed, which places great emphasis on intangible wealth and solidarity, and great responsibility of humanity for the ecological state of the native country; provides a higher standard of living as a result of sustainable development, through the introduction of information technology in this system. To improve the quality of life, we need better knowledge, which must be implemented through information technology at the international level.

Bacteria that are resistant to high temperatures and alkaline environments are essential for the biological repair of damaged concrete. Alkaliphilic and halotolerant Bacillus sp. AK13 was isolated from the rhizosphere of Miscanthus sacchariflorus. Unlike other tested Bacillus species, the AK13 strain grows at pH 13 and withstands 11% (w/v) NaCl. Growth of the AK13 strain at elevated pH without urea promoted calcium carbonate (CaCO₃) formation. Irregular vaterite-like CaCO₃ minerals that were tightly attached to cells were observed using field-emission scanning electron microscopy. Energy-dispersive X-ray spectrometry, confocal laser scanning microscopy, and X-ray diffraction analyses confirmed the presence of CaCO₃ around the cell. Isotope ration mass spectrometry analysis confirmed that the majority of CO₃^2- ions in the CaCO₃ were produced by cellular respiration rather than being derived from atmospheric carbon dioxide. The minerals produced from calcium acetate-added growth medium formed smaller crystals than those formed in calcium lactate-added medium. Strain AK13 appears to heal cracks on mortar specimens when applied as a pelletized spore powder. Alkaliphilic Bacillus sp. AK13 is a promising candidate for self-healing agents in concrete.

This study was conducted to modify the surface properties of papers by formation of hydrophobic self-assembled monolayer(SAM) on paper surface with silanes. A base paper I(0.5% AKD) and base paper II(1.0-1.5% AKD) were reacted with silanes(PFDTES, DMDCS, MODDCS) by immersion method and vapor deposition method. Hydrophobic SAMs(contact angle value>$120^{\circ}C$) were obtained on all papers after treatment with $10^{\mu}l$ PFDTES for 15min, with $50^{\mu}l$ DMDCS for 30min, with $50^{\mu}l$ MODDCS for 300min. When applying PFDTES to paper surface, lower silane concentration and shorter reaction time were required, whereas MODDCS with long alkyl chain required the longest reaction time of 300min. The st$\ddot{o}$ckight sizing degree of silane treated papers were increased between 105sec(base paper I) and 130sec(base paper II). The wet tensile strength of PFDTES-treated base papers(I, II) increased by 10-34% after SAM formation. However, the wet tensile strength of the DMDCS-treated base paper(I) was found to decrease from 0.067kN/m to 0.038kN/m; this may due to the cellulose degrading as a result of generated hydrogen chloride when hydroxyl group of cellulose were reacted with DMDCS. No apparent changes of PPS roughness on silane-treated papers are observed. The ATR-IR spectrum showed absorption peak located at 465 and 1200cm-1 which can be assigned to the Si-O-C asymmetric stretching and Si-O-C bonds, respectively.

The purpose of this study was to analyze the educational program that is offered on the information menu in the homepage (Familynet) of the Healthy Family-Support Center (HFSC) and suggest developmental directions. For this purpose, first, it deduced that the managerial principles of the education program, from related theories, are included in the family-system, family-structure, family-structure analysis, family life-cycle and ecological system theories. Second, it analyzed the educational programs of 44 local centers that are connected to the homepage (familynet.or.kr) of HFSC. Finally, it suggested developmental directions for managerial improvements of educational programs. As a result, the most popular part in the educational program was parent education, especially the visiting-father education program. The number of couple-related education programs were fewer than those for parent education, because it is difficult for couples to be present at the same time. Family and Self-Cognition programs cover insufficient contents in the parent-education program. Though total program in familylife education is quite large, the number of programs in each separate part is far too small for such a wide subject. So, each part in the program should be made more sufficient. Finally, it suggested the development of an evaluation system and a coaching process as special services for families that are in different development stages and have different family experiences, resources, needs and goals.

Founding himself on 'The Principle of Self-making' that is the instrument of 'the natural construction' and accomplishing the various interdisciplinary researches, Frei Otto could explicate the fundamental structure of life that is able to make visible the self-making processes in the nature, the technique and the architecture. It is the flexible pneumatic construction that is grounded on the fibrous organization. This was a milestone not only for him who wanted to put the idea of the new architectural form into practice, but also for the contemporary architecture that faces on the style-pluralistic disorientedness. The architectural form of the natural construction includes in itself three constitutional sub-ideas. One of them is 'the adaptable architecture', which is inclined to the architecture similar to the organization of human body, and the other 'the light architecture' that is in the pursuit of the optimal form through the minimal material. The last one is 'the ecological architecture' that aims to realize the optimal dwelling environment based on the effective energy consumption by accumulating knowledges of the always fluid and unstable nature. With these architectural ideas Frei Otto could develop a new architectural form language 'the light architecture of the natural construction'. This study is purposed to explain the various experiments that were made by his team and the basic principles of the structural dynamics of 'the architecture of the natural construction' and then to analyze the structures that were built on the ground of those principles.

Self-thinning was measured in Salix communities on Bam Island in Seoul at various age stages. $D^2H$ was used to estimate tree biomass, where D is stem diameter at breast height or 10 cm height for plants with height <1.5 m, and H is height. A log-log plot of density versus $D^2H$ and correlation analysis indicated a significant relationship between density and biomass with equation 'log $D^2H$ = -1.27 log N + 7.06'. This indicates that self-thinning affects biomass in the Salix community with -1.27 as the thinning coefficient. If we assume a thinning exponent -3/2, then the allometric coefficient of the equation, log w = a log $D^2H$ + b, is 1.18. This is much higher than that for any other species studied in Korea. There were statistically significant relationships between age and density and between age and basal area and these relationships suggest guidelines for transplantation of willows and for the assessment of Salix community restoration projects in riverine wetlands based on standard density, basal area, and age. The results of this study may also increase understanding of succession processes in Salix community restoration in riverine wetlands.
