On the basis of sustainable long-term water resources planning, the development of ground water resources should be interlocked with the surface water development In considering the intertemporal equity, overpumping of groundwater may diminish or eliminate the groundwater resources stock of post-generations. Regulatory landuse zoning for groundwater resources recharge area is indispensable measures to prevent groundwater pollution. Adequate treatment of polluted water from various sources such as municipal sewage, industrial wastewater, landfill site leachate, and abandoned boring wells, is also necessary for groundwater protection. To preserve groundwater resources as common property goods, groundwater use tax should be imposed upon the large scale groundwater use. Finally, the establishment of groundwater development license system is recommended to achieve the social optimal production and to avoid external diseconomy.

As far as recent investment in railway, disused railway yards is increased in each line and region. As a result, related local government and agencies has been increased interest for utilization of disused railway yard. In this study, we investigated the status of the disused railway yards and conducted legal review on the use of disused railway yards. In addition, we analyze the disused railway yards use practices through case analysis and suggest plans to diversify ways to use.

The variations of cleft lip deformities imposed the difficulty to the surgical correction for them. Straight line technique for cleft lip surgery has been ignored quite long since other techniques were developed. Initially the straight line technique was introduced and widely accepted because it is simple and easy to perform during the period of no adequate anesthetics. But it was abandoned for its several shortcomings such as tighten lip, vermilion notching, anatomical distortion, and wound contractures. Recently, some groups advocated the usefulness of straight line technique which has a significant modification from its original form. Additionally the variable degree of cleft lip deformity allows simple straight line closure for those patients. Here a case of simple straight line technique was presented and discussed for its reliability and plausible results as well.

This paper examines Japan's Science and Technology (S&T) Basic Plans in accordance with its S&T Basic Law. The Basic Plans promote two major innovation (Green Innovation and Life Innovation) towards the creation of new markets and jobs, specifically under the Fourth S&T Basic Plan enacted on August 2011. Successful smart community demonstration projects at four urban localities were launched under plans to promote Green Innovation research and development of renewable energy technologies. However, the expectation that renewable energy such as solar or wind power can replace nuclear power is not backed by sufficient evidence. Furthermore, the electricity produced by these sources is expensive and unstable owing to its reliance on weather conditions. The Fukushima nuclear power plant accident on March 2011 has also seriously affected Japan's future energy plans. According to a government estimate, electricity charges would double if nuclear power generation were abandoned, imposing a heavy burden on the Japanese economy. Japan is in need of energy policies designed on the basis of more far-sighted initiatives.

As expensive and valuable metals being used in electronic and semiconducting industries are abandoned as industrial wastes after use of them, it is required to recover them from e-wasted electronics parts. Gold which is used for printed circuit boards or electronic equipments, accessories, etc., is one of e-Wasted materials and recently indium, gallium, zirconium, cobalt, molybdenum and lithium are bacome valuable metals to be recovered from the e-wastes. Since the amount of precious metals is now being faced with scarcity, lean too much on area and instability of supply, and industrial demands are rapidly increasing every year, it becomes more important to recover the valuable metals from the industrial wastes. In this review, we introduced technologies and research trend of the recovery processes of valuable metals from the e-wastes in high-tech devices over the world.

Recently produced concrete has a tendency to overcome environmental defects. Porous and planting Eco-concrete requires the neutralization process and enough void in concrete to contain water, to pass air freely, and provides necessary nutrients to vegetation roots. The biological environment in concrete is not suitable for planting because the concrete possesses strong alkali constituent of pH 11-13. This study evaluated the strength and serviceability of concrete as well as the chemical characteristics of concrete mixed by low-grade iron ore left in the abandoned mine and treated by Ammonium monohydrogen phosphate, $(NH_4)_2HPO_4$. Test variables include two kinds of coarse aggregates such as crushed stones and low-grade iron ore, the duration time and the period for neutralization treatment by Ammonium monohydrogen phosphate, $(NH_4)_2HPO_4$, and the proportion ratio of cement, blast furnace slag and silica fume.

Most parts of facilities in domestic petroleum plants and power plants are needed to be abandoned, repaired or replaced, because in Korea they were built in the 1960s and, they have been used under severe conditions and exposed corrosive environments. 2.25Cr- lMo steels have excellent high-temperature mechanical properties. Therefore, the material have been widely used as heat exchanger tubes, boiler headers and its tubes in such industries. But, those microstructural evolutions in high temperature such as precipitation and carbide coarsening give a reason to degrade the material. Especially, in case of this material, carbides induced embrittlement(CIE) is the primary reason for degrading mechanical properties at over 50$0^{\circ}C$. In this paper, we introduce a electrochemical polarization method for detecting CIE quantitatively.

This study explored the life histories of intermarried Korean men for more than one year before and after their family dissolution. Researcher had in-depth interviews with participants who were selected by purposive sampling from the intermarried Korean men with dissoluted family conditions. Researcher employed the holistic-content approach to analyze the interviewed materials. Mandelbaum(1973)'s conceptual framework-dimensions, turnings, and adaptions-has been taken to present the analyzed contents. The dimensions of men consisted of 'request of continuous money', 'limitation of comprehensible communucation', 'premise terminated marriage: leaving home', 'inassurance of marriage maintenance'. Turnings involved 'abandoned person', 'parents' excessive protection', 'community among themselves', and 'greedy mediator'. Adaptions were observed by 'various feeling card', 'worrying about men's child', 'expecting the future', and 'stopping on foreigner as a partner'. Discussion and suggestion were presented on the basis of these findings: examination of marriage genuineness, Korean men's preparation of marriage, intervention and service for their mental health, supports for their children and strengthen of multicultural family center's function for dissolved family.

본 연구에서는 낙동강, 영산강을 대상으로 과거 사행하도 구간을 직강화함에 따라 절단된 폐천의 형태를 조사하고 이에 대한 유형화를 수행하였다. 폐천 및 구하도 구간을 선정하기 위한 기준은 1918년 근세한국오만분지일지형도를 이용하여 현재의 수치지도와 좌표보정 후 중첩, 비교함으로써 폐천 구간을 파악하였다. 낙동강의 경우 인위적 변형(하도절단형)에 따른 유형분류로 살펴보면, 세부적으로 하도보존형, 타용도전용형, 하도유실형은 각각 9 개소, 2 개소, 3 개소로 조사되었다. 영산강은 세부적으로 하도보존형이 4 개소로 나타났고, 타용도전용형, 하도유실형이 각각 4 개소, 10 개소로 나타났다. 이와 같은 폐천 현황 조사결과는 향후 구하도 복원을 위한 대상지 선정 시 기초자료를 제공하는 기회를 마련할 수 있을 것으로 판단된다.

The purpose of this study is to make an in-between space considered as an abandoned thing to the central place of commercial area by utilizing it to form the each places' identities. The methodology of the design is not about one complete form but about a continuous process by negotiation. This process is proceeded by holding council between public institution and private owners of the buildings and applied the rules to various cases in similar places in the commercial area. This project has been developed in order to construct a healthy network to connect buildings nearby and programs in a block. This place could provide the ground for public communication between any group to visit this place and make the spatial milieu of the city.
