The objective of the present study is to review of the system, type of care and utility of the Geriatric Health Care Facility(GHCF) in Japan. Geriatric Health Care Facilities in Japan were started with subsidies from the Ministry of Health and Welfare in 1987 to encourage return of the elderly from hospitals to their homes rather than other destinations such as nursing homes or hospitals. Concerning to the type of care, there is the difference between GHCF and other geriatric care facilities(i.e., geriatric hospital and nursing home). GHCF provides both medical and nursing care. The following services are available for the GHCF's user's. As institutional care services, rehabilitation training, ADL exercise, nursing care and management of medicine, are available. For the out-patients, supplying meals, taking a bath, and rehabilitation services, are also available. The medical treatment fee at the facilities is about US $ 1,500 per month. Expenses for meals, daily necessities, shall be borne by the recipient, Those expenses are about US $ 360 per month. In anticipation of the coming of the aging society, the Goverment must be formulated consecutively several vital policies of measures, especially GHCF, for the elderly in the future few years.

In this study, large-current (75 - 400 A), high-voltage (500 - 1000 $V_{rms}$), reliable capacitors with capacitances (C) of 100 - 1000 nF were developed for energy storage facility applications. Mica was used as the dielectric of the capacitors. In order to form a parallel stack of a capacitor element, 50 ${\mu}m$ thick mica sheets with a size of $30mm{\times}35mm$ were used with lead foils for the plate lead type of mica capacitors (HCM-L), while the same sizes of mica sheets coated by Ag paste were employed with lead foils for the parallel plate terminal type (HCM-C). The developed capacitors exhibited well behaviored device characteristics which meet the requirements of the capacitors. The developed capacitors also showed excellent characteristics for thermal shock test. The stability characteristics of developed capacitors for large current stress was superior to those measured for the capacitors prepared recently by CDETm.

The purpose of this study was to improve the refuge safety area in the high-rise building type. Each simulation was conducted to evaluate the performance of three types in improving the refuge safety area. Targeting the first 63 floors (no refuge safety area), secondly, to target up to the $30^{th}$ floor (refuge safety area on the $30^{th}$ floor, $47^{th}$ floor) specified in domestic laws, and finally, the $20^{th}$ floor (evacuation safety area on the $20^{th}$ floor, $42^{th}$ floor) were considered as targets. Through this analysis, the following results were obtained : The floor for the refuge safety area through simulations showed that the evacuation time is low. It is necessary to improve the floor for the refuge safety area by using the characteristics of the domestic fire fighting vehicle. The first floor for the refuge safety area from the ground floor differs according to the distance and height of the building floor. However, in the case of a business facility it is 15F, and in the case of apartment housing, it is 20F.

The purpose of this study is to propose our direction of long-tenn care facility for elderly. The long-tenn care insurance plays an important role for human well-being. The functional and architectural changes of Japanese elderly care facilities have been analysed in order to predict changes in Korean welfare facilities. In Japan, Unit-care and private rooms are essential elements after reforming welfare facilities for aged. This study proposes components of unit-care through the analysis of 20 facilities for the aged. A unit is basically consist of private rooms, rest room, public living area, kitchen, health care service station, and bath room. Besides, smoking room, tea room, public terrace, guest room, court yard, and so on can be added. A unit can be connected with other unit by semi-public spaces or can be independently organized. This relationship has been classified into 2 types; Open unit type and Separated unit type.

The present study performs a test of a change in a condenser pressure on two kinds of power plants having different condenser pressure-heat rate correction curve and evaluates the results. According to a result of the test, it is confirmed that a sub-critical drum type steam power plant is optimally operated at the condenser pressure of 38㎜Hga that is designed, even during winters. On the other hand, it can be found that a supercritical once through type steam power plant operated at the condenser pressure that is reduced below a design value, that is, up to 28㎜Hga during winters is advantageous in view of turbine efficiency and is operated without a problem in facility operation such as moisture erosion, turbine vibration, etc. Also, the present study compares and reviews a condenser pressure-heat rate correction curve proposed by a manufacturer and a test value. The present study proposes optimum condenser operation pressure capable of concurrently satisfying the stable operation and efficiency improvement of the power plant facility that is operating, making it possible to support an efficient operation of a power plant.

This paper details a testing facility ("NATURAL FIRE FACILITY") that allows closely-controlled experimental testing on full-scale sub-frames while reproducing the spatially transient temperature conditions measured in real fires. Using this test facility, an experimental investigation of six steel sub-frames under a natural fire was carried out at the Department of Civil Engineering of the University of Coimbra. The main objective of these tests was to provide insight into the influence of these connection types on the behaviour of steel sub-structures under fire. The experimental layout is defined by two thermally insulated HEA300 columns and an unprotected IPE300 beam with 5.7 m span, supporting a composite concrete slab. Beam-to-column connections are representative of the most common joint type used on buildings: welded joints and extended, flush and partial depth plate. Finally, the available results are presented and discussed: evolution of the steel temperature; development of displacements and local deformations and failure modes on the joints zone.

Objectives : This study aims to analyze differences in the use of postpartum care services and identify the factors affecting their use. Methods : Data were collected from the 2008-2014 Korean Health Panel. Chi-square tests were conducted to analyze differences in the characteristics of women after birth by the use of postpartum care services. Logistic regression analysis was used to identify factors affecting the use of each type of postpartum care service. Results : Participants with higher education and household income levels were more likely to use a postpartum care facility. Individuals with a lower number of household members, who gave birth in 2011-2013, and who used hospitals specializing in obstetrics and gynecology had a greater likelihood of using a postpartum care facility. The probability of using a postpartum caretaker was higher when participants did not perform any economic activities. Conclusions : It is meaningful to confirm that use patterns and determinants of postpartum care facilities and postpartum caretakers are completely different and that the socioeconomic status of women affects the utilization of postpartum care facilities.
