Aging is characterized by an age-dependent reduction in bone density. Pronounced bone loss by postmenopausal estrogen deficiency induces a bad effect on dynamic balance of bone metabolism. The purpose of this study is to examine what are the effects of the Ssangbohwan(SBH) on the ovariectomized rat model of postmenopausal osteoporosis. The results were summarized as follows : 1. Body weight in control group showed significant increase in comparison with sham, but that in SBH-treated showed no change in comparison with control. 2. The level of serum albumin in control group showed significant decrease in comparison with sham. That in SBH-treated was slightly decreased in comparison with control, which showed no efficacy. 3. The level of serum ALP activity in control group showed significant increase in comparison with sham, but that in SBH-treated was slightly decreased in comparison with control, which showed no efficacy. 4. The level of serum phosphorous in control group showed significant increase in comparison with sham, but that in SBH-treated showed no change in comparison with control. 5. The level of serum calcium in control group showed no change in comparison with sham, but that in SBH-treated was significantly decreased in comparison with control. 6. The level of serum T3 in control group showed no change in comparison with sham, but that SBH-treated showed significant decrease in comparison with control. 7. The level of serum T4 in control group showed significant increase in comparison with sham, and that in SBH-treated showed significant decrease in comparison with control. 8. Trabecular tibia strength in control group showed significant decrease in comparison with sham, but that in SBH-treated was slightly imcreased in comparison with control, which showed no efficacy. According to the above these results, SBH has shown to be capable of preventing and curing osteoporosis caused by old-aged and postmenopause

Research on unused energy continues due to the limits of fossil fuel and the destruction of the environment. Therefore this study was performed as follows. The collectable amount of exhausted heat for an air-conditioning was calculated by the subway thermal environment prediction program. And the electric power needed by conventional heat source equipment was compared with one by unused heat source equipment when the exhausted heat was used by heat pump in heating and hot water supply. The results are summarized as follows 1. Forced ventilation should be conducted to keep optimal temperature in the subway tunnel in summer as well as in winter. According to the simulation, the temperature in tunnel was higher than that on the ground in summer when the forced ventilation was conducted only in the winter. 2. Ventilating time should be calculated out to the optimal condition for not only the saving power of the ventilation fan but reusing exhausted heat. By the simulation, it is certain that the exhausted heat should be eliminated in air-conditioning time. 3. The use of the exhausted heat source heat pump could save 8% of electric power per hour in comparison with existing heat pump. This was based on a present heat generation and traffic for ventilating time of general air-conditioning, but could be different by ventilating time. 4. As the traffic increases up to 1.5 or 2 times, electric power consumption of the conventional heat pump increases to 11% or 13.5% per mean hour in comparison with that of the exhausted heat source heat pump, though all-day ventilation.

Since the 1930s there has been a running debate about the relative efficacy of monetary and fiscal policy. Especially, the controversy accelerated in many empirical studies since the St. Louis model was developed by L.C. Andersen, J.L. Jordan, and K.M. Carlson. They conducted firstly the empirical test on the subject by using the St. Louis equation[Andersen-Jordan(1968), Andersen-Carlson(1970)]. Their conclusion is that monetary policy has a significant and lastinf effect on nominal GNP but fiscal policy has no lasting effect. A number of critiques appear after the publication of the A-J and the A-C papers. The criticisms are focused on various technical and applied econometric aspects of their works such as the specification error, simultaneous equation bias, inappropriate indicators of policy actions, and inappropriate restrictions. The purpose of this parper is to survey the literature of the empirical results and the criticisms that emerges following the publication of the St. Louis equation, and finally to evaluate the St. Louis model that has been used mostly as a forecasting tool.

The humidity control is conducted not only for industrial applications but also for domestic ones. High humidity is a factor causing discomfort, thus the importance of using a LiCl(Lithium Chloride) solution has been recognized in recent years in connection with the high quality of goods to be manufactured. as well as cleanliness in a special environment against air pollution and environmental protection. This paper will examine the solar energy regenerator as a part of an open cycle solar energy absorption system for dehumidifying and drying purposes using LiCl solution. An outdoor experiment was done to find out how much could be regenerated in summer. It was found that regeneration rate was about 10kg/day at best in August, and about 5kg/day in September.

For the purpose of processing weather data for air conditioning equipment design in Busan area Korea, this study collected weather observations made by Busan weather Administration from 1970 to 2003, and then established external conditions for heating and air-conditioning design. For changes of temperature in external conditions for design, the highest temperature had little changed, whereas the lowest had been on the rise as the years went by through the 1970s, 1980s, 1990s, and 2000s, but insolation has a little lessened. Absolute humidity does not show a significant change but an incessant rise.

The subject of this study is development of wave height algorithm and sensor. Principle of wave height algorithm was written and made with vertical acceleration measurement by means of an accelerometer placed on a Tilt Assembly System. The field-test of two times for data analysis of wave height sensor was lasted for 8 days with Development Sensor Buoy, Waverider Buoy(Waverider-SG) and Wave Radar(SM-050) in the east costal area. In data analysis of Development Sensor Buoy and Waverider Buoy, the implications of the results were a difference not exceeding 20㎝.
