Purpose: In 2012, the Child Welfare Act was revised to provide better support to children with severe disabilities in Japan. Previously, inpatient facilities had been classified according to the type of disabilities of patients. After the revision of the Act, however, these facilities were assigned into the category of "medical-type facilities for children with disabilities", or "welfare-type facilities for children with disabilities." The focus of the study is to evaluate the reorganization of the Child Welfare Act and to analyze the new layout of Center K after its transition from a facility for children with motional disabilities to a medical-type facility for children with disabilities. Methods: A literature review was conducted to identify the trend in the treatment for persons with disabilities and the process of policy making in Japan. Field research was performed twice in 2015 and 2016, before and after the renovation of the Center K facilities depending upon the revision of the Child Welfare Act. Results: There is an increasing tendency of the population of persons with disabilities in Japan, and the severity level of disability of children with disabilities. In the case of Center K, two types of ward constructed to meet the two types of disability has been reconstructed into three types of unit following the various severity level of disability. Implications: As a result, it could be argued that it is also necessary in Korea to reorganize the facilities for persons with disabilities to deal with the fact that the population of persons with disabilities in Korea has been growing and their degree of disabilities also getting severe.

Most of the intake facilities of small agricultural reservoirs are conduits and they are regarded as serious defects due to the structural weakness that penetrates the body of the dam, and countermeasures are needed. This study suggests the application method of siphon type water intake facility by hydraulic model test and physical scale model test of siphon type water intake facility which has high safety and easy maintenance. Experimental results show that sufficient flow rate can be secured for the purpose of intaking water according to the differential head between the reservoir and the discharge part, and the flow rate can be controlled by the valve. The negative pressure was -31.5 kPa, and vibration and noise did not occur during the operation of the siphon. The maximum flow velocity in the discharge outlet was 1.11 m/s which meets the criterion for irrigation canals. Therefore, scour risk would be very low. As a result of the inflow distribution experiment, even if the inflow part is separated by only about 0.8 m, the flow velocity is remarkably decreased, so that the clogging by debris would not appear. When the pump was operated only once for the first time and the inside of the siphon was filled with water, continuous operation was possible by only valve operation. The results of this study are expected to be used for the design guidelines of the water intake facilities and improve safety and maintenance convenience of agricultural reservoirs.

Over the years, great attention has been shown to the function of the campus facilities that should be well-equipped, operated and maintained to better support university's two main goals: providing education and supporting research. Properly managing campus facilities is the initial step to be prepared to meet the rapidly changing global educational standard. However, so far, no definitive answer has been given to the question of what service level/scope is appropriate for the effective campus facility management (FM) in Korea. Therefore, at the outset, it is imperative to establish the framework for the standardized campus FM services. The main focus of this research is to provide comprehensive understanding on the campus FM by establishing the framework in the form of FM performance indicator (PI). As the first step, FM standards set by Korean Agency for Technology and Standards (KATS) has been thoroughly reviewed and analyzed to establish the framework for FM standards applicable to campus facility management. Secondly, extensive literature review on the development of performance indicator (PI) for the educational facilities has been conducted to classify PI types and complement FM_KS. Finally, specific guideline and PIs developed by APPA which is globally well-known association in the field of FM for higher education facilities has been added to the combined PI which is the mixed form of FM_KS and PIs from the previous literature. This research provides campus facility managers and FM outsourcing service providers with framework in the form of PI to support future directions of effective campus FM services.

In this research magnetic field reduction effect of each passive loop was analyzed by using the scale down models of transmission lines. This paper examined magnetic field reduction effect of the passive loop that will be applied to actual facility through the experiment, which is about double vertical transmission line and horizontal transmission line. Consequently, by confirming the fact that magnetic field reduction effect can be obtained to 50 % by passive loop without reactive compensation, we insured technology about application of passive loop. And the case of 3 turns of loop showed two times reduction effect than that of 1 turns of loop in reducing magnetic field. Vertical passive loop is more efficient than horizontal passive loop in the aspect of reducing magnetic field on double vertical transmission lines. What is more, vertical passive loop showed good effect of reducing magnetic field in a far distance as well as in a short distance.

The aim of this study was to examine the scale and market share of Chinese's research facility & equipment in the domestic research equipment market of basic and analytical science field for analyzing the difference of the number and amount of construction by year of acquisition, national research facility equipment standard classification code, and type of institution based on the information of the research equipment invested by the Korean government for the past 14 years. In addition, we analyzed the correlation among the year of acquisition, equipment standard classification code, and type of institution variables. As of January 1 2019, from 2005 to 2018, 50 Chinese's research facilities & equipments (main equipment with a construction cost of 30 million won or more) built in the basic and analytical science fields were selected for this study and their number of construction, amount of construction, year of acquisition, type of institution, and standard classification code were analyzed. Differences of the number and amount of construction with-in and by year of acquisition, standard classification code, and type of institution were tested using a single sample Chi-square test, Mann-Whitney U test, and Kruskal-wallis test. The correlation among the three variables was analyzed by using the Chi-square test of cross-tabulation analysis. And there was a statistically significant correlation among the year of acquisition, standard classification code, and type of institution (p<.05). Compared to the 2000s, in the 2010s, high-priced Optical Electronics/Video Equipment was installed at private universities, private enterprises, and government-affiliated research institute. Therefore, the domestic construction status of Chinese's research facility & equipment in the basic science and analytical science field is less than that of the domestic ones, but the number and the amount of construction are increasing statistically. So it is necessary for the government to be able to recognize the possibility that the Chinese's research facility and equipment can encroach on the domestic research industry market and to prepare related provision.

The objective of this research study was twofold; 1) to explore and identify health supportive design factors in Swedish elderly care homes and 2) to understand their usefulness and suggest implication in Korean elderly care settings. A descriptive and explorative method was applied using a combination of field studies and semi-structured interviews. Three study trips were carried out during Sept. $14^{th}$ and Oct. $12^{th}$ 2005; two facilities situated in Stockholm suburbs and one in the south of Sweden. According to this research, the valuable factors to support health and well-being for the elderly are as follows; 1) Community integration: These elderly care homes are generally places close to a residential area center or a city center. Services are often shared between residents and community members at large, consequently there is a flow of "visitors" of all ages connecting with the facility on a daily basis. 2) Homelike environment: A noteworthy aspect of Swedish elderly care homes is keeping the facility appearance as homelike as possible. The associations with home may be explored through the appearance and configuration of both the exterior and interior of the building. These homes seemed to be designed with a conscious aim to create a homelike setting. 3) Small scale approach: Clustering of resident rooms is one method through which the small scale approach can be achieved in larger facilities. With unit clusters, the facility can foster opportunities for social interactions among resident. 4) Accessibility to garden and nature: The courtyard is a well developed concept in planning elderly care homes in Sweden. They are generally safe and easily accessible to the residents. Studying Swedish models may provide practical knowledge of how the physical setting may improve resident's health in Korean elderly care homes.

Recently, improvement of materials and technologies for the manufacturing of gas pipe has it possible to reduce the buried depth. Compared to the criteria from advanced countries, Korea has conservative criteria for the buried depth of pipeline(about 50cm deeper). Therefore, this study investigated the effect of various buried depth(0.8m, 1.0m, 1.2m) on the stress and strain distribution of gas pipe. Numerical analysis and field tests were carried out with API 5L steel gas pipes. From the results, it can be suggested that the change of buried depth would not significantly affect the stress and strain distribution of gas pipe.
