Since the National Geographic Information System(NGIS) project of 1995, the geographic information projects have been promoted in various areas such as central and local governments. In the fact that large scale budget has been invested to geographic information projects as a national policy, the cost-benefit analysis would be essential to enhance the efficiency of the resource allocation. In this circumstance, this study analyzes the costs and benefits of geographic information produced by NGI(National Geography Institute). As a result of the cost-benefit analysis, the total amount of benefits were estimated approximately 620 million dollars and the accumulated ratio of the cost to benefit was 1 to 4.4. Also, the internal ratio of the benefit was 38%, which justified the large scale investment. In case of adding qualitative benefits which can not be measured in a quantitative term, the overall benefits from using such geographic information would be much higher than quantitative benefits. Further research work is required for more objective verification of the large scale national project such as building nationwide geographic information.

The core technologies of the current transport network are OAM and protection switching to meet the sub-50ms protection switching time via a path redundancy when a link or node failure occurs. The transport networks owned by public network operators, central/local governments, and major enterprises are individually configured and managed with service resiliency in each own protected sub-network. When such networks are cascaded, it is also important to provide a node resiliency between two protected sub-networks. However, the linear protection switching in packet transport networks, such as MPLS-TP and Carrier Ethernet, does not define a solution of dual node interconnection. Although Ethernet ring protection switching covers the dual node interconnection scheme, a large amount of duplicated data frames may be flooded when a failure occurs on an adjacent (sub) ring. In this paper, we suggest a dual node interconnection scheme with linear protection switching technology in multiple protected sub-networks. And we investigate how various protected sub-network combinations with a proposed linear or ring protection process impact the service resiliency of multiple protected sub-networks through extensive experiments on link and interconnected node failures.

Waste lubricating oil(WLO)s have been recycled as energy source through direct fuel in cement kilns and fossil power plants, or as fuel oils, or re-refined lubricating base oils. In our country, they have been recycled as low grade fuel oil through chemical treatment process. In 2003, extended producer responsibility (EPR) system was adopted from deposit system on sale of lubricating oils in order to promote their recycleing rate. However, our recycling rate of WLOs have been stagnant(below 70%) for last 5 years. And there has been no research work on recycling of WLOs as re-refined base oil until now in this country. Stabilization technology of thermally cracked oils to reduce tar and malodor and to improve their color for production of high grade fuel oil, and a novel process production of high grade re-refined lubricating base oil from WLOs have been developed and commercialized recently in Canada and U.S.A., respectively. Several countries like Australia, Italy, Germany and U.S.A., etc. are encouraging recycling companies to recycle WLOs as re-refined lubricating oil by giving greater subsidies or benefits compared to other recycling methods. They also adopt a policy to purchase re-refined lubricating oil preferentially in the federal or local governments and to recommend consumers to purchase it willingly. Based on the facts that several advanced countries have adopted a policy to recycle WLOs as re-refined base oil for saving of petroleum resource and reduction of environmental pollution, it is right time to be considered that our present policy for recycling of WLOs should be reevaluated and the new policy of their environmental-friendly and sustainable recycling should be established.

This study aimed to analyze the relative influence of related variables on the university students' civic consciousness. The study sorted out the data for 1,200 university students from a larger data set collected by Son et al.(2009), and analyzed the data by a hierarchical regression analysis method. The study showed the major results in four aspects. First, personal characteristics and home environment variables had mostly no influence on the students' civic consciousness. Second, on the sub categories of the students' civic consciousness, almost no influence was found in case of the home environment variables on democratic constitution and participation-practice, and in case of the school environment variables on value and attitude. Third, among the home and school variables, parents' attitude(${\beta}$=.228) and professors(${\beta}$=.162) had positive influences on the students' civic consciousness. The results suggest that parents and professors should be the two principal axises in the cultivating process of the students' civic consciousness. Third, on the democratic participation and practice no positive influences were found in any of the social environment variables. Among the social environment variables, politicians(${\beta}$=-.238) and corporations(${\beta}$=-.097) had rather negative influences on the democratic participation and practice. These results raised the question on how school education and social political systems are operated in the democratic manners. Fourth, the study recommends that local government would establish the civic education centers, develop various civic education programs, and provide each school with the programs. The study also recommends that each university would democratize in all the school affairs, and actively implement the civic education for university students as a specialized project.

One of the fastest growing sectors in tourism industry is the use of applications from the MICE industry in various parts including business, politics, and cultural exchange due to globalization among the countries. The means-end chain theory suggests that convention participants perceive and judge convention destination as the means to achieving a desired end-state in a given destination selection situation. This study aims at establishing a convention destination's attributes, the benefits of consequences of using it, and the personal values it satisfies. A laddering interview was conducting in order to provide in-depth probing and to elicit responses from 96 visitors. This study presents the unique pyramid-structure of the means-end chain; a model linking perceived convention destination attributes to values. Understanding these concepts provides opportunities for convention destinations to target market segmentation and advertising based on the participants' desired end-states. In conclusion, the major correlations of attributions of the visitors, consequences, and the values are; informativeness(A), activity(A), tourist attraction(A) - sympathy(C), human relations(C) - self-development(V), and fellowship(V).

Recently, our company has entered the modern knowledge company, government policy and regulation has a big influence on people's lives. Also, unlike in the past, I am hoping for administrative intervention as a problem peculiar to the environment, such as environmental housing problems, urban transportation problems, misuse problems, etc. and corporate pending issues. In this study, through the 10th year of the Seoul Special Citizen Judicial Police Force, if the local autonomy is a special envoy, it will try to present the correctness in the organization luck. As a measure to secure the nature of administrative action, the method of investigation was through the study of the execution process of administrative penalty and its result based on the statistical data of Seoul City. Therefore, we will analyze the process and operation of the 10-year organizational change of the Seoul Metropolitan Government's police force and examine how the police force of the people's livelihoods, which is a special investigation organization, is expanding its duties in order to strengthen the enforcement power of the administration. Also, we will make future-oriented suggestions to encourage the readjustment of the current relevant laws, such as the Ministry of Patriots and Veterans Affairs, and to actively accommodate the expected changes of the special law police organization in charge of the enforcement of the police system.

This study examines the case of living lab applied in the R&D initiatives for solving societal problems and challenges. It discusses how to use the living lab in national R&D projects. The analyzed cases are 'Develop portable fundus camera for eye disease screening test to resolve health inequalities' and 'Auto-sensing integrated system development in rural pedestrian crosswalk'. As a result of the analysis, both cases were designed as a user participatory R&D structure by utilizing living lab. In other words, living lab has operated as a system that evolves technology-products-services into an infrastructure. It can realize final demand specification, product, service improvement and demonstration through continuous interaction of end users. As a result of the case analysis, the following policy tasks can be derived. First, living lab is a new concept and it is in the early stage of implementation in Korea. Therefore, it is necessary to monitor and evaluate living lab experiments and build suitable models for Korean society by sharing cases and achievements. Second, the strategic niche management are necessary for the introduction of living lab. Third, living lab can be used as a tool to transform the existing technology acquisition centered innovation policy to the policy for customer needs and problem solving. Fourth, there is a need for flexibility and adaptability in strategy and system to correct errors that appear in the living lab processes.

The Purpose of this study is to provide an effective way of developing GIS to UIS at the local level. For this purpose, the study typologically reviews the developing processes of UIS and utilizes a case study as research method. As the case, the study selects three types of UIS such as FM based UIS(Kwacheon), Urban Planning based UIS(Cheungju), and LIS based UIS(Taegu Nam-Gu). Based on these three UISs, the study concludes as follows. First, the developing process of GIS to UIS began with isolated approach through integrated model and finally to internet UIS. Second, UISs follows similar processes to that of GIS construction. Third, local governments focus on the development of FM based UIS of which construction budget is financed by the central government. Based on these findings, the study provides policy alternatives for the successful construction of UIS.

Governmental accounting system has changed from budgetary accounting on the basis of cash and bookkeeping by single entry to financial accounting on the basis of accrual and bookkeeping by double entry. In the context of this transition, infrastructure becomes considered an asset in accounting, and resulting accounting methods also take different approaches from conventional budgetary accounting. Financial accounting system defines expenditures into two categories, i.e. capital expenditure(CAPEX) and operational expenditure(OPEX), and stipulates that the expenditure shall be divided into those two categories before accounting. The construction and expansion of infrastructure must be considered a CAPEX because it means a sort of asset acquisition, but with regard to applications in practical accounting, it is actually challenging to judge whether any expenditure associated with maintenance works (including repair and service) during use of infrastructure acquired shall be considered CAPEX or OPEX. This paper suggested an asset management based accounting method for sewer maintenance expenditure. And it applied the method to actual accounting cases and analyzed them in comparison with conventional financial information. As a case study result, Sewer asset value of S city increased approximately 700 hundred won because sewer maintenance expenditure are classified between OPEX and CAPEX according to the proposed accounting method. It is expected that the proposed accounting method will contribute significantly to providing any proper sewer asset value information.

For successful privatization of environmental facility, a sound environmental policy is required to satisfy social motivation and economic. The primary purpose of environmental facility is not profit, but to supply a good quality service, an efficient management tool is needed to run the facility. In foreign countries, the privatization policy was originally based on the principle of complete competition achieving economic effiency. There were efficient cooperation and division of labor between civillian and public sector. First of all, the local government had independant budget. But, we found that the environmental facility have two important problems, the first is low effiency of operation and the second is comsumed to government finances as a homemade rate 50% in the technic application For a successful privatization of the environmental facility, The law of private capital introduction should be amended to promote fund raising. There are some other strategies ; overcoming of Nimbyism, research development of the privatization, field trip to the successful foreign environmental facilities. To support an efficient privatization policy, the environmental budget should be managed by cost-benefit analysis.
