  • In this study, the current regulation of the water source energy, one of the renewable energy, was analyzed, and the improvement plan for the high efficient data center cooling system was suggested. In the improvement plan, the design and construction guidelines of the water source energy system permit to adopt the cooling and heating system with or without heat pump. In addition, it should also include the system operated in the cooling mode only all year-round. The domestic test standards to consider the water source operating conditions should be developed. Especially, it is highly recommended that the test standards to include the system with forced cooling and free cooling modes related with the enhanced data center cooling system adopting the water source energy.

  • The dichotomous-choice contingent valuation method is applied to estimate the landscape value of Jeju mandarin(orchard). A distribution-free approach, Turnbull empirical distribution model, is employed to solve negative willingness to pay and truncation problems. The data used are collected from the interviews with tourist about willingness-to-pay at the various donation amount levels of Jeju mandarin(orchard)'s landscape value. The evaluation result is shown that the average amount of willingness to pay for the Jeju mandarin's landscape value is 12,926 won per person with standard deviation of 1,874.7 won/person. When the number of Jeju visitors is considered, the economic value of Jeju mandarin's landscape rises every year(2005:64.89 billion won, 2011: 84.43 billion won). The average economic value of Jeju mandarin's landscape are estimated 59.65 billion won during 2000-2005 and 76.88 billion won during 2006-2011, respectively.

  • In India, the current operation of condenser cooling system & effluent disposal system in existing power plants aims to reduce drawal of seawater and to achieve Zero Liquid Discharge to meet the demands of statutory requirements, water scarcity and ecological system. Particularly in the Steam-Electric power plants, condenser cooling system adopts Once through cooling (OTC) system which requires more drawal of seawater and effluent disposal system adopts sea outfall system which discharges hot water into sea. This paper presents an overview of closed-loop technology for condenser cooling system and to achieve Zero Liquid Discharge plant in Steam-Electric power plants making it lesser drawal of seawater and complete elimination of hot water discharges into sea. The closed-loop technology for condenser cooling system reduces the drawal of seawater by 92% and Zero Liquid Discharge plant eliminates the hot water discharges into sea by 100%. Further, the proposed modification generates revenue out of selling potable water and ZLD free flowing solids at INR 81,97,20,000 per annum (considering INR 60/Cu.m, 330 days/year and 90% availability) and INR 23,760 per annum (considering INR 100/Ton, 330 days/year and 90% availability) respectively. This proposed modification costs INR 870,00,00,000 with payback period of less than 11 years. The conventional technology can be replaced with this proposed technique in the existing and upcoming power plants.

  • The authors present a unique case of osteonecrosis of a cortical half of a fibula free flap that has not been reported in the literature yet. This complication was associated with the impairment of the vascularization of periosteum in the cortical half of fibula that was fixated with a nonlocking reconstructive 2.0-mm plate and screws but other factors could have been involved. The patient was submitted to excision of a cemento-ossifying fibroma that resulted in a left hemimaxilectomy mesoinfrastructure defect classified as the Cordeiro type 2B. The 42-year-old female patient was submitted to reconstruction with an osteomusculocutaneous fibula free flap plus a segment of fibula graft. The two bone segments of the free flap used to reconstruct the anterior and left alveolar crest were fixated with a reconstructive 2.0-mm plate of matrixMANDIBLE system. The only reported complication was an oronasal fistula that healed with conservative treatment and the referred osteonecrosis of the external cortical half of the fibula free flap with plate exposure at 2.5 years postoperatively. Surgical excision of the osteonecrosed cortical half of the fibula with the plate and screws was performed, while the other cortical underwent bone union as corroborated by computed tomography scans.

  • The author installed $3.75mm\times10mm$ $Br{\aa}nrmark$ osseointegrated implants and $3.5mm\times8mm$ I.T.I. hollow screw implants(Benefit) as a free standing abutment to replace lower left and right molars of 44-year-old female patient. Form the foregoing procedure, the author obtained the following results. 1. Free-standing $Br{\aa}nrmark$ and I.T.I. Hollow screw implants(Benefit) could be used to replace molars effectively without reduction of adjacent natural teeth, 2. Rotation of occlusal gold screw of $Br{\aa}nrmark$ implants was observed under occlusal force. 3. Adjustment of height of I.T.I. abutments was necessary in the mandibular second molar because of the limited occlusal clearance. 4. Form the oral examination, patient comments, panoramic and periapical radiographs, there were no pain, gingival imflammation and mobility, but slight reduction of alveolar bone level was shown around both implant systems. 5. Patient comments were comfortable on both systems. but the patient complained about economic problem of $Br{\aa}nrmark$ system and long treatment treatment time of both systems.

  • The establishment of the WTO system means that the global age of trade has officially arrived. Since the integration of the world economy brings about the free movement of goods and services between nations, it is inevitable that sea-bound freight will continue to increase. A recent World Bank report says that China and Korea will be the first and seventh largest economic Powers, respectively, by the year 2020. In particular, the Korea peninsula has a geo-political advantage in being developed as a major Northeast Asian container center. Moreover China's swift uprising needs new order of trade for economy belt in Northeast Asia. Therefore, it can be said that Kunsan Port. which has already been designated as a free trade zone, has greater potential to rise as a regional beach-head port and main region for foreign investment. As such. Kunsan Port will play a major role in accelerating the emergence of the West Sea in international trade. There are several strategies for developing Kunsan Port into a central container port: 1) develop Kunsan port Into an import/export front base f3r multinational corporations, 2) develop Kunsan container port into the core composite container-linked central port, 3) attract foreign investment to the Kunsan Free Trade Area so as to promote balanced development among the regions of Korea, 4) support the central government and local governments to accelerate the coming of the "West Sea Era." These recommendations call for urgent implementation.

  • 첨단 미래사회에서 우리는 왜 삶을 위협하는 다양한 위기로부터 자유로울 수 없는가? 재난은 습관적이고 제도화된 행동 양식을 중단시키고 사람들을 사회적 개인적 변화에 따르게 하는 일종의 사회적 충격을 낳는다. 역사적 재난 사례연구는 역사적 재난의 맥락 이해를 통한 현재 재난관리의 재검토가 가능하고, 미래 재난을 해결하기 위한 해답을 찾을 수 있다. 또한 재난 관리의 새로운 패러다임과 방식을 도출할 수 있다. 이 논문의 주된 목적은 역사 속에서 나타난 재난관리를 통한 현대 국가의 재난관리의 발전 방향을 발견하는 데 있다. 연구결과에서 흥미로운 사실은 1925년 을축년 대홍수 당시 재난관리 컨트롤타워 역할이 적절히 이루어졌고, 일원화된 재난관리 체계로 유관기관과의 협조가 원활히 이루어 졌다는 것이다. 그리고 재난관리 조직의 동기부여를 통한 조직몰입에 긍정적 영향을 미쳤다. 역사의 기록을 통한 성찰과 학습을 교훈삼아 현재의 제도 개선을 끊임없이 이루어 나간다면 미래 안전사회를 위한 혜안을 찾을 수 있을 것이다.
