Although the demand and necessity for the facilities of nature environmental conservation and its utilization have been increased recently, the local governments has been experiencing difficulties to launch the facilities since there are no confirmed principles or guidelines for the direction of the facility and distinctions from the ordinary parks. In this regard, the aim of this paper is to provide the overall framework for establishing the facility by equipping checklists from planning to operational stage. The stages are disengaged into 5 steps of siting feasibility, planning, preliminary environmental assessment and environmental impact assessment, design, construction, and operation. This paper also include the recommendations to vitalize the existing facilities, of which expansion of educational program development; utilization of various manpower; provision of appropriate settings; strengthened monitoring; and increased public relations. Furthermore, it is suggested to consider the strengthened local characteristics, reviewing management plan at the stage of applying a new facility establishment to the concerned authority, fostering experts, and expansion of the facilities through restoration of environmentally damaged areas for a new facility.

This study analyses the management and utilization of Korean inland fisheries and suggests directions for reorganizing the fisheries in order to achieve qualitative growth. Inland fisheries developing into a unique fishery according to various aquatic systems in different areas have played various roles such as the efficient use of aquatic resources, development of local areas and economy vitalization in under-developed local areas. However, recently Korean inland fisheries are facing a lot of difficulties due to the circumstantial changes surrounding the fisheries. Even though it is difficult to expect the external expansion of the Korean inland fisheries, we could expect qualitative internal growth by achieving the sustainable management and aquatic ecosystem health. Therefore, this study suggests the followings in order to achieve the qualitative growth of the Korean inland fisheries : first, construction of integrated management system according the aquatic systems ; second, organization of fishermen's interest groups such as cooperatives or associations in order to increase the competitive advantage and spread voluntary fisheries management ; third, boosting stock enhancement through systematic stock assessment and stocking ; fourth, expansion and activation of administrative system and research organizations.

There are many types of the geometric transitions such as dent, bulge, protrusion, expansion, etc, on the inner and outer surfaces of heat exchanger tubes, steam generator tubes, and condenser tubes of nuclear power plants. Such geometric transition causes a local residual stress in heat exchanger tubes and acts as a structural factor accelerating the evolution of defects, in particular stress corrosion cracks. In the conventional eddy current test methods, the bobbin coil profilometry can provide 2-dimensional geometric information on the variation of the average inner diameter along the tube length, but the 3-dimensional distribution and the quantitative size of a local geometric transition existing in the tube cannot be measured. In this paper, a new eddy current probe, developed for the 3-dimensional profile measurement, is introduced and its superior performance is compared with that from the conventional bobbin coil profilometry for the various types of geometric transition. Also, the accuracy of the probe for the quantitative profile measurement is verified by comparing the results with that from the laser profilometry. It is expected that the new eddy current probe and techniques can be effectively used for an optimization of the tube expansion process, and the management of tubes with geometric transitions in service.

This study aims to investigate the effects of e-purchasing on increasing transparency, expanding market access, and the efficiency of the government procurement process. This study also investigates how transparency of the procurement process, improved market access and the efficiency of the procurement process in e-purchasing will decrease the level of fraudulent government procurement in Indonesia. The questionnaires were distributed to the Procurement Service Units (ULP) of Local Governments through email. There are currently 542 ULPs in Indonesia based on the data of the Government Procurement Policy Institute (LKPP). However, only 520 ULPs had their email addresses traced, 120 ULP returned the questionnaires and the response rate is lower than it was expected. The data research was analyzed by a structural equation model (SEM) by using WarpPLS 7.0. The results reveal that the e-purchasing effect on the transparency, the expansion of market access, and the efficiency of the government procurement process. The other findings show the negative effect between efficiency in government procurement and fraud in government procurement. The findings of this study suggest that efficiency in the process of government procurement will minimize fraud in government procurement. However, transparency in government procurement and the expansion of market access was not sufficient to minimize fraud in government procurement.

In this study, we reviewed access transportation, operating companies, and airport infrastructure to revitalize Cheongju International Airport. Regarding access transportation infrastructure, it is necessary to promote a railway network connecting the metropolitan inland line and the central inland region. In addition, active administrative support from local governments is required to ensure smooth progress in railway and highway infrastructure linkage projects, such as the Osong Connecting Line and Chungbuk Line, high-speed rail network promotion, and expansion of the Chungbuk Eastern Axis Expressway and Central Expressway. Regarding operator access infrastructure, continuous efforts are required to add and attract airlines based at Cheongju International Airport. Regarding airport infrastructure, the Cheongju International Airport runway needs complete resurfacing due to its deterioration. Domestic passenger capacity has exceeded 6.5%, and considering the increase in import and export of high value-added goods in the North Chungcheong region, it is necessary to build and expand passenger terminals and cargo terminals. Cheongju International Airport's runway does not have enough runway length to operate large and ultra-large aircraft, so if it is extended from the existing 2,744m to 456m to 3,200m, several benefits can be expected in terms of revitalizing Cheongju Airport, such as route expansion.

As the demand for natural gas that satisfies environmental regulations increases, the quantities of natural gas cargo that carrier can load is also increasing. Natural gas is transported in a liquefied state at -163 ℃ to increase loading efficiency. Among several LNG CCS types, MARK-III types are generally adopted in terms of loading efficiency. The secondary barrier adhesives of the MARK-III, nevertheless, is subjected to tensile stress due to thermal contraction and tension in the environment. In terms of these reasons, local analysis of the adhesive to evaluate the stress state must be carried out. According to previous studies, local analysis is unavailable since material properties for secondary barrier adhesives have not been reported. Thus, in this study, the cryogenic tensile test and coefficient of thermal expansion of epoxy and polyurethane (PU15, PU45), which are most widely used at cryogenic temperatures, were experimentally analyzed. At cryogenic temperature, the mechanical behavior of the polyurethane adhesive was better than epoxy of the adhesive. the joint of FSB and epoxy adhesive of the secondary barrier has the maximum coefficient of thermal expansion difference at 25 ℃ and minimum at -150 ℃, respectively.

By the IMF condition, tax revenues of local governments are decreasing, under these conditions, container tax take important proportion in financial resources in Pusan Metropolitan City. However the container tax have time limit until 2001, that is, purposeful tax. But after the creating container tax, the level of accomplishment is very insufficient. So for the activation of local economy, we need active study on the existence problem of container tax. Though the abolition of container tax item is frequently discussed in central government, If the worst case comes, namely the abrogation, it gives big damages to the financial management of Pusan Metropolitan City. Therefore the container tax should be existent for both residents and local government. Because the expansion rate of container tax is so rapid, it makes very critical contribution to the stability and sound condition of Pusan Metropolitan City's finances.

This paper aims to examine the characteristics of social enterprises in Jinju City, Korea and to provide policy recommendations for promoting the competitiveness of local social enterprises. There are 11 social enterprises in Jinju City that are certified by central and local governments. The survey shows that the majority of social enterprises in Jinju City are based on the local community and their activities are public in nature, including supporting the self-reliance of local under-privileged class or contributing to local socio-economic development. However, it is also revealed that local social enterprises have a great deal of difficulty in making a profit. Particularly, they have much trouble with sales of their services and products, largely due to the vulnerability of marketing and financial ability. This means that the local social enterprises are not capable of being viable in a severe market competition. Thus I suggest some important policy recommendation for invigorating local social enterprises, including the reform of governance system, expansion of public purchase of the products made by local social enterprises, and the facilitation of inter-organizational networking among local social economy agents.

On the framework of Tolman spacetime model, the caustics around a local perturbed region in redshift is due to the local expansion rate induced by a local density inhomogeneity in real space. We have compared the caustics in redshift space, which are analytically obtained, with the observed redshift-distance patterns of galaxies which are belonging to Coma and Perseus clusters. For the Abell density distribution model and polytropic density profiles which are well-fitting the optical and X-ray observations, respectively, the size of caustics which is defined by "turnaround radius" of a local density perturbed region should give constraints on the sizes and masses of rich clusters and give also a clue to understand the state of hot X-ray emitting gas.

This study was conducted to explore ways to create a cultural city using local cultural resources. To that end, the qualitative case study was applied. As the original city center had been declining due to the expansion and changes of city space caused by the changes of city function and social change, the old downtown of Andong city was selected as an example. For the result, research shows that the region's historical resources and culture have to blend and develop together with abundant cultural resources, such as contents development, city's symbolic space settings, differentiated cultural and artistic establishment, comfort in living, utilization of cultural infrastructure, and supporting facilities which are suitable for cultural diversity. In particular, we found that the importance of establishing a new city image that leads local residents willing to participate and of forming a consensus among tourists. Therefore, for the implementation of a cultural city, policies, undertaking, and administrative support that meet to the city's conditions and environment are required, and a further study on that issue is needed.
