Due to the increase of aged housing demolition in preparation for the rapid growth of the market, Eco-friendly remodeling demolition work which can minimize environmental destruction have been studied. However, the owner or contractor to apply for eco-friendly remodeling demolition work does not reflect the characteristics of the site can not have a potential for many variables. In addition, There is no standard which can find effective part and catch a problem by performing eco-friendly remodeling demolition. Therefore, the project owner and construction company executives in the Pre-construction stage to the implementation of eco-friendly remodeling demolition construction by providing a model for the pre-evaluating the project. In this paper, the performance of eco-friendly remodeling of demolitions is proposed for the pre-evaluating model. After the eight items were drawn affecting the performances which are influence to accomplishment of the eco-friendly remodeling demolition, evaluation criteria was suggested for each item. Also By classifying and assessing the evaluation items, It will be able to identify the problems and supplements for eco-friendly remodeling demolition. Through the final evaluation sheet, The works of the appropriacy and supplement will be checked for the eco-friendly remodeling demolition. Finally The preinvestigation model is helpful for making the plan of systematic demolition, futhermore It is contribute to the expansion of the eco-friendly remodeling demolition.

Tourism is a major sector of the national and regional economy in Southeast Asia endowed with rich natural environment and a variety of cultural and historical heritages. Tourism has been recognized as the industry without chimneys. However, as tourism sector is getting larger and being globally standardized, various problems such as environmental degradation as well as profits leakage from locals have been gradually aggravated. Against negative impacts from massive tourism various efforts have been tried and community-based ecotourism(CBET), seeking environmental conservation and community development at the same time, has emerged as a noteworthy alternative. By comparing the two cases of CBET in Indonesia and Cambodia, this paper aims to review the current status and future challenges of community development through ecotourism in Southeast Asia's rural villages. In the concrete, this paper analyses in-depth on case of JED(the village ecotourism network) in Bali, Indonesia and CBET project in Ramsar wetland reserves of Steung Treng province, Cambodia and founds out the possibility and main obstacles of community developmental strategy through CBET. Both cases have proven the positive outcomes in terms of environmental protection, local people's awareness improvement, and direct/indirect economic gain from CBET project. However, there are significant, but differentiated limitations in management capacities and stabilities of internal governance of two villages. Both villages are still in need of brisk networks with and assistance from the outside. In the conclusion part, this paper suggests CBET development program in Southeast Asia through Korea's social enterprises as one of the possible ODA programs(in tourism sector).

The Cancun Agreements under the United Nations Framework Convention on Climate Change require developing countries aiming to undertake REDD+ activities to develop a national strategy or action plan, addressing the drivers of deforestation and forest degradation, a measurement, reporting and verifying (MRV) system including forest monitoring system, and safeguards to ensure equity and co-benefits for local communities and indigenous peoples, and biodiversity. The Government of Indonesia and the Government of Norway established REDD+ cooperation through signing a 'Letter of Intent' in May, 2010. Indonesia agreed on 'a two year suspension on all new concessions for conversion of peat and natural forest'. In turn, Norway agreed to support Indonesia's REDD+ implementation efforts up to one billion United States dollars. Indonesia's REDD+ national strategy (June, 2012) accepted most of the requests included in the 'Letter of Intent'. The REDD+ national strategy, however, does not reflect requests of the Cancun Agreements which noted identification of the drivers of deforestation and forest degradation and guarantee of real greenhouse gas emissions reductions. Indonesia lays emphasis on Norwegian requests which includes expected financial support rather than the Cancun Agreements which have a weak legally-binding requirements.

The International Civil Aviation Convention (Chicago Convention) has been a backbone of international air transport system whereby air transport between States should be based on bilateral agreements, and in particular, international airfares, which are set up through IATA(International Air Transport Association) rate-fixing machinery could be approved by the governments concerned. International airfares are fares for transporting passenger and freight and their conditions between two or more countries. However, since U.S. pursued th deregulation policy in 1978 whereby routes, capacity and fares could be freely determined by airlines, many States have been following so called open-skies agreements. In many cases, aeronautical and competent authorities have been reviewing whether airlines' commercial activities including air fares could possibly conflict with free competition rules envisaged in relevant laws and regulations. As competition among airlines gets intense, airlines often resort to cooperation with other airlines in the forms such as equity exchange, M&A, code-sharing, fares consultation and resource pooling, mainly with a view to effectively use resources available and to avoid monopoly situation resulting from excessive and destructive competition among players. Whereas bearing in mind that application of competition laws is important to secure consumers' interests by preventing airlines's malpractices such as bargaining exorbitant fares, it is also important to comprehensively consider as many factors as possible, from that unilateral measure by governments may bring about retaliatory measures by the governments affected, to that airlines' cooperative practices may rather increase consumers' benefits by lowering air fares.

Although international construction market gradually takes a important position among the export industries, the previous studies about international construction entry strategy have just focussed on trend investigation or suggestion for revitalization. Moreover, in order to prepare the market uncertainty such as world financial crisis and to plan the long term strategy, specific strategy studies based on corporate level are required. Therefore, this study estimates the nine strategic index and four financial index of 31 companies that performed 1920 international projects from 1993 to 2007 and evaluate the performance as three periods by multi-regression analysis. Also, this study analyze dynamic correlation between these index and the performance considering times. this study verifies that market diversification, product diversification, localization and decrease of debt to asset ratio make a good effect on the international order as long term strategy and shows that collaborated entry with domestic corporations, alliance entry with host country's company, alliance entry with third country's company, portion of labor cost and portion of management expense differently make a influence on the performance as times. these results will be helpful for the construction companies to plan the international entry strategy reasonably and specifically.

This paper deals with the cancellation performance of loop back interference signal in the case of multihop relay of 16-QAM received signal at the USN radio network. For this, it is necessary to the exchange of information with long distance located station by means of the relay function between the node in the USN environment. In the relay node, the loop-back interference signal which the retransmitting signal is feedback to the receiver side due to the antenna of transmitter and receiver are co-used or very colsely located or using the nonlinear device. Due to this signal, the performance of USN system are degraded which are using the limited resource of frequency and power. For improve this, it is necessary to applying the adaptive signal processing algorithm in order to cancellating the unwanted loop-back interference signal at the frontend of receiver in relaying node, we can get the better system and multi hop performance. In the adaptive signal processing, we considered the 16-QAM signal which has a good spectral efficiency, firstly, than, the QR-Array RLS algorithm was used that has a fairly good convergence property and the solving the finite length problem in the H/W implementation. Finaly, we confirmed that the good elimination performanc was confirmed by computer simulation in the learing cuved and received signal constellation compared to the conventional RLS.

The purpose of this study is to find out the structural and developmental characteristics of inter-organizational community network of the school social work and the characteristics of direct workers and the school social work organizations delivering services to the children in low-income families, and to identify the magnitude of efficient structure for networking for the children living in Kayang-dong. By searching out the central organization and block modeling, this study attempted to show the characteristics of inter-organizational community network for the children. The research sample was 18 organizations, and the data were collected by a survey questionnaire and analyzed by SPSSWIN 12.0 and UCINET 6.29. The main results show that the social welfare organization is the central organization in almost every dimensions(information exchange, client referral, cooperation, resource exchange) and education organizations play an important role in betweenness centrality. Also it can be evaluated that the present developmental stage of the network is collaboration. Based on the research results, implications for the future practice are discussed.

The service that has been recognized as both a non-productive activity and auxiliary activity of manufacturing have become the driving force of the customers' demand with the 'service' itself. The service base is expanding and evolving rapidly. It is important to look at changes in service concepts to understand service systems. Because the service system itself has a cyclic nature based on the concept of service, it can help in the study and the "how" of service by looking at changing the system according to the evolution of the service concept. The ability to organize and utilize relationships is considered to be an important factor for managers in the service economy era. However, the attention of corporate is focused on their internal capabilities and they are familiar with external resources (knowledge and competence of customers). In this case study for each type of service, we analyzed the activities of interacting service providers-consumers in service relationship, and constructed a new service system model emphasizing intangible value and long-term outcome. This study is worth re-examining the role of customers in today's service economy era and actively utilizing a new service model for business performance.

The construction of National Spatial Data Infrastructure (NSDI) started from 2008 and was completed at 2012, with the aim of co-utilizing public agencies' national spatial information by integrating and linking. Despite the existence of the NSDI, an update of spatial data is not fully reflected because the spatial information has not been updated simultaneously by NSDI and public agencies. By examining the public agencies' services using the spatial information, a national budget is wasted because the re-usable similar services are duplicated. These issues could be solved by adopting a cloud system, whose concept is co-utilizing IT resources, to the NSDI. This study examined the service cloud based expansion and development plan for NSDI. The plan included an implementation strategy for a spatial information service cloud system and an establishment plan for a governance system. The service scenarios, concept diagram, and service functions for the system were derived in a system implementation plan. For the service functions, the unit functions of two modules were proposed and specific functions were derived. In the establishment of a governance system, the business roles and business processes were defined for organizations managing service cloud based NSDI. The business role and process were defined and derived by each service life-cycle step. With the proposed system implementation plan, a detail system design and composition of the organization could be possible, and a service cloud-based NSDI system could be implemented.

This study reviews recent changes in parenting support policy in Japan, and examines the roles and functions of day-nursery as the base for parenting support in the local community. The purpose of this study is to provide implications for the direction of the parenting support policy and child-care facilities for the local communities in South Korea. The analysis concentrates on the official national reports such as the Declining Birthrate White Paper and Japan's National Guidelines for Care and Education at Day Nursery by the Japanese Cabinet Office. The study finds that the Japanese government has introduced comprehensive medium and long-term policies for all the members of the community with recognizing the changes in the domestic and foreign child-rearing environments and social needs. These policies have also helped to improve the social awareness of parenting. The role of the day-care center has been raised as a significant part of the support for child-rearing in the local community due to the revision of the Child Welfare Act for nursery school teachers in 2001 and the official announcement of Japan's National Guidelines for Care and Education at Day Nursery in 2008. The study also concludes that the social responsibility of the nursery center has been strengthened by being utilized as a public resource for the community. From the findings, we can elicit the conclusions and implications that the roles and functions of child care centers as a significant base for parenting support in the local communities need to be considered. We also listen to the voices of stakeholders such as parents and staff of child care centers. Last but not least, we would understand the social role and importance of bringing up children by cooperation of the community members, and promote the role of child care centers as a central place providing and communicating information on child-rearing in the local communities.
