The problem of outdated and surplus facility-items in existing Rural Living Environment Renewal Program(RLERP) makes this study focus on restricting the range of facility sorts for the purpose of coㅁins with the changing rural living environment. In the four aspects of plan establishment, project implementation, comprehensiveness and linkage between programs, this study made an analysis of the existing RLERP that has 4-stage hierarchy, namely, Gun(county), Myun(primary administrative district), village and project site level Firstly, Myun and upper level policy programs fulfill the comprehensiveness and planning aspects, but have defects in the implementation and linkage aspects. Secondly, the village level programs satisfies more or less the four condition, but give rise to the problems of equity between the project target village and the non-target, and of generalization of the planning method applying to a specific village. At last, project level programs, controlled by several ministries, have defects in comprehensiveness and linkage aspects, exposing the sectoralism of central government. Above all, the existing RLERP has so many facility items, which have led to inefficient investment till now. Therefore, it's necessary that the environmental facilities should be selected(simultaneously reduced ), referring to following 5 criteria. (1) Exception of facilities relating to agricultural production. (2) Confined to public facilities to be constructed by government support. (3) Common-use facilities located in small town and below level area. (4) Consideration of not only the present need but also the future need of rural residents. (5) Reflection of a regional difference of mountain, plane and suburban area. Just 13 kinds of living environmental facilities are finally selected as the result of the selecting work, which can be an new alternative for RLERP. Concludingly, the selected facility items should be integrated into a designated project site by the prepared plan in order to enhance the efficiency of RLERP, investment and also to satisfy the four analytic aspects mentioned above.

This study was conducted to survey and inspect the currently operating anaerobic digestion facilities for animal manure. Recently, the number of anaerobic digestion facility for livestock manure is on the rise thanks to growing interest in developing alternative energy. A anaerobic digestion system has been constructed in large scale farms or animal manure public resource center. Currently, most animal manure anaerobic digestion facilities in operation are producing biogas from the pig slurry which contains 97% water. Methane gas can be used to operate a engine generator which then produces electricity. Anaerobic digestate, a by-product of digestion, is mostly utilized as a liquid fertilizer after curing processing. Only in a few cases, it can be discharged after wastewater treatment process. The problem of anaerobic digestate treatment is the imbalance of C/N ratio. The content of N was too high to keep it into normal process.

The propose of this study was to investigate the management characteristics of assisted living facility(ALF) as an housing alternative for semi-dependent elderly. For this purpose, 5 ALFs which have been well known as best practices in rural Virginia were selected for a multi- site case study. Face-to-face interview with administrators or assistant administrators of i facilities were done. In addition to this, written materials about the each facility and personal record from researcher were used to analyze the data. Six management categories including 82 open-ended questions were analyzed and successful examples and management difficulties were identified from best practices. Based on the results, some recommendations for development of ALFs in Korean elderly were suggested. In short, this study found that best practices which were selected and analyzed in this study showed that successful management was resulted from continuous efforts of the stalls to provide better services in order for improving the quality of life of their residents.

Eco-village adopted its basis on continual notion as one of the alternative dwelling models in the dwelling sector and it suggests a dwelling pattern of modern society. Ansolgi village was organized in 2000 as an intended Eco-village for the first time in Korea and after 8 years, the village seems different to that of the earlier period. The cause of the difference can be originated from changes of planning strategies and notion of life. The village is different from its original design due to lack of space resorted from installation of many facility and overall layout of the village. The different look of the village can be categorized in 4 types; village layout, community facility, Eco-based facility and hydro circulation. Therefore, the purpose of this paper is to suggest actual data about Eco-village establishment plan by performing a comparison analysis on the current status and the initial design on the basis of the intended Ansolgi village, the village that had been organized 8 years ago.

The rectilinear-distance location problem combines the property of being a very appropriate distance measure for a large number of location problems and the property of being very simple to treat analytically. An obvious question to be asked at the optimal point which is obtained by the rectilinear distance method is, "what if the point is not available as a location site\ulcorner." The point may, for example, be inaccessible or may coincide with the location of another structure, a river, or a municipal park. In this case, one approach that may be employed is to construct contour lines (also called iso-cost or level curves) of the cost function. Contour lines provide considerable insight into the shape of the surface of the total cost function as well as a useful means of evaluating alternative locations for the new facility. But, when there is an obstacle which divides the application area into two. The optimal location(which is acquired by the rectilinear distance method) is not coincide with the minimal cost point and the contour line is occasionally of no use, this paper shows the method of finding a way to decide an optimal point of single facility location in this case.this case.

Two different type scramjet models with side-wall compression and top-wall compression inlets have been tested in HPTF (Hypersonic Propulsion Test Facility) under the experimental conditions of Mach number 5.8, total temperature 1700K, total pressure 4.5㎫ and mass flow rate 3.5kg/s. The liquid kerosene was used as main fuel for the scramjets. In order to get fast ignition in the combustor, a small amount of hydrogen was used as a pilot. A strut with alternative tail was employed for increasing the compression ratio and for mixing enhancement in the side-wall compression case. Recessed cavities were used as a flameholder for combustion stability. The combustion efficiency was estimated by one dimensional theory. The uniformity of the facility nozzle flow was verified by a scanning pitot rake. The experimental results showed that the kerosene fuel was successfully ignited and stable combustion was achieved for both scramjet models. However the thrusts were still less than the model drags due to the low combustion efficiencies.

This study is intended to prepare an revitalization plan of region where rural development project is completed through an analysis of the actual condition of facility operation and maintenance in the region where the project is completed. The results of survey of actual condition of facility operation in the region where rural development project was completed showed that the facilities were not self-sufficient in terms of operation and maintenance cost. Therefore, a prerequisite to the revitalization of region where the project is completed is to prepare an alternative plan for increasing the efficiency and applicability of currently already prepared facilities. Second, a project operation organization system should be streamlined and the competency of operation personnel should continue to be strengthened. Third, it is necessary to prepare a support system and establish cooperation networks for increasing the extensibility of project and continuing to induce community revitalization in the region where the project is completed in the future.

The purpose of the target system for the muon spin rotation, relaxation, and resonance (µSR) facility at the Rare isotope Accelerator complex for ON-line experiments (RAON) is to induce the production of a significant number of surface muons in thermally stable experiments. The manufactured target system was installed at RAON in the Sindong area near Daejeon in 2021. The design was made conservatively with a sufficient margin of safety through ANSYS calculations; however, verification experiments had to be performed on the ANSYS calculations. Because the 600-MeV proton beam has not yet been provided, an alternative way to reproduce the calculation conditions was required. The radio frequency (RF) heating method, which has not yet been applied to the target verification experiment but has several advantages, was used. It was observed that the RF heating method has promise for testing the thermal stability of the target, and whether the target system design process was performed conservatively enough was verified by comparing the RF heating experiments with the ANSYS calculations.

Recently, with traffic SOC investment policy changing from road-centered to railway-centered according to environment-friendly and sustainable development, issues regarding overlapping and overinvestment of traffic facility have been raised. Regarding investment of various traffic facilities of which departure and destination are similar to each other, academia, civic organizations, government, etc. are recognizing problems including overlapping investment of budget, environmental destruction, etc., but not suggesting definite solutions. Objective transportation network analysis is required because various positive effects including solutions of delay/congestion may occur due to provision of alternative way and distribution of the amount of traffic when accidents occur, as well as negative effects suggested by some of civic organizations in various transportation facility investment of similar departure and destination. Hereupon, this study tries to suggest a tool that can objectively evaluate interrelations of transportation network by applying multi-criteria analysis including economic feasibility regarding analysis of interconnections between and within means of transportation.
