Korea's modern waterworks began with construction of DDukdo water treatment plant in 1908 and has been growing rapidly along with the country's economic development. As a result, water supply rates have reached 98.5% based on 2013. Despite multilateral efforts for high-quality water supply, such as introduction of advanced water treatment process, expansion of waterworks infrastructure and so on, distrust for drinking tap water has been continuing and domestic consumption rate of tap water is in around 5% level and extremely poor comparing to advanced countries such as the United States(56%), Japan(52%), etc. Recently, the water management has been facing the new phase due to water environmental degradation caused by climate change, aging facilities, etc. Therefore, K-water has converted water management paradigm from the "clean and safe water" to the "healthy water" and been pushing the Smart Water City(SWC) Pilot Project in order to develop and spread new water supply models for consumers to believe and drink tap water through systematic water quality and quantity management combining ICT in the whole water supply process. The SWC pilot projects in Pa-ju city and Go-ryeong county were an opportunity to check the likelihood of the "smart water management" as the answer to future water management. It is needed to examine the necessity of smart water management introduction and nationwide SWC expansion in order to improve water welfare for people and resolve domestic & foreign water problems.

When the castle of the city was destructed from 1911 through 1915 in Cheongju, the city's spatial structure was reorganized and "Han-ok Housing", a dwelling site filled with Korean traditional houses, was newly formed around the former castle site. These days, the Han-ok housing in Seoun-dong, Cheongju in which elderly couples and senior citizens live is enclosed by modernized roads and three or four-story buildings, leaving the housing as an isolated island in the city block. Nonetheless, the Han-ok housing not only plays an important role in sustaining the historic and local identity of the city, but also offers environmental benefits in terms of daylighting and ventilation. The purpose of this study is to reorganize the housing suitable for those who currently live and recreate it by adding new functionality. Consequently, three strategies are established; the conservation of existing building through the improvement of existing facilities; the conversion of vacant buildings into a new use; and the creation of the urban mid-rise Han-ok housing at street sides. The first strategy has a significance in that the traditional building's single wing plan, small room sizes and lack of storages now cause great inconvenience for current life style. The second strategy also promotes the practical use of abandoned buildings through alterations and additions. Finally, the creation of the urban mid-rise Han-ok housing that is accomplished by the combination of reinforced concrete and wooden structure interacts with or respond to the city's development. As a result, this study for the adaptive reuse of Han-ok housing proves how the traditional properties can be maintained in a careful manner and how its creative reuse can be achieved.

During the liquefaction of hydrogen, the ortho hydrogen is converted into the para form with heat release that evaporates the liquefied hydrogen into the gaseous one backwards. The ortho-para conversion catalysts are usually used during liquefaction to avoid such boil-off. In order to compare and analyze the performance of the ortho-para hydrogen conversion catalysts, in-situ FT-IR device was designed and manufactured to measure the para hydrogen conversion rate in real-time. $LaFeO_3$ and $La_{0.7}Sr_{0.3}Cu_{0.3}Fe_{0.7}O_3$ perovskite catalysts were prepared by the citrate sol-gel method and their spin conversion characteristics from ortho to para hydrogen were investigated by in-situ FTIR spectroscopy at 17K. It was found that the spin conversion was affected by surface area, particle size, and crystallite size of the catalysts. Thus, the $La_{0.7}Sr_{0.3}Cu_{0.3}Fe_{0.7}O_3$ perovskite catalyst that had higher surface area, higher crystallite size, and smaller particle size than $LaFeO_3$ showed the better spin conversion property of 32.3% at 17K in 120min interaction with the perovskite catalysts.

This paper studied the present condition of social welfare activities of Living Condition Improving Committee of Kimpo City in order to activate the social welfare services of women agricultural organizations. The main results are as follows; First, the general characteristics of the respondents in this study are forty or fifty years of age with above high school education with main income source of agriculture and middle class women living in agricultural communities more than 10 years. Second, considering the present and future planned activities of the Living Condition Improving Committee of Kimpo City this study finds that there is high expectation of helping poor people and joining voluntary services. Third, the members of the Living Condition Improving Committee of Kimpo City have actively participated in the local welfare service programs however, there is significant difference among people according to the age, living standard and joining period. Fourth, out of social welfare activities managed by the Living Condition Improving Committee of Kimpo City the welfare service activities for old people and local community are most active and the participants in the welfare service activities for women and the youngsters are small. Thus, according to this study the Living Condition Improving Committee of Kimpo City should consider the following three points in order to activate the social welfare service activities; First, as the members are expecting to expand the individual activities and to enhance the private improvement, the social welfare service activities should meet with the demands to improve self satisfaction of the participants. Second, new programs should be developed after reviewing the current programs in order to meet with the need of the members. Third, as the committee has not established a network system with government administrative organizations and relating institutions, and as its activities are concentrated in particular areas the committee should establish a new system to provide more efficient services in line with the cooperation with public organization and welfare resource suppliers.

본 연구는 대규모의 주택건설로 신도시가 지속적으로 형성되고 있는 수도권 지역에서 도시성장에 따른 주택시장의 분화에 영향을 주는 요인과 공간적 분화 패턴, 주택하위시장의 분화와 교외화의 관련성 등을 실증적으로 규명하고자 하였다. 용인시는 지리적 장점뿐만 아니라 주택시장의 제도적 사회적 환경 변화가 강력히 뒷받침해준 결과 2000년대 수도권 지역에서 가장 역동적으로 성장한 지역으로 주택시장의 변화에 관하여 미시적 스케일에서 주택하위시장의 공간적 분화 패턴을 밝히기에 적합한 장소이다. 용인시 주택시장은 4개의 하위시장으로 대별되었는데, 이에는 강남 분당과의 접근성, 경부 및 영동고속국도 등의 지리적 요인, 주택규모와 가격, 점유형태 등 주택재고의 특성, 그리고 세대구성 학력 및 소득수준 등의 사회경제적 요인이 중요하게 작용하였다.
