The Recently, several countries have been affected by respiratory diseases, resulting in renewed research interest in their prevention and control. One such example was the 2015 outbreak of Middle East Respiratory Syndrome (MERS) in South Korea and COVID-19. In this study, we performed experiments and simulations based on concentration decay using CO2 as the tracer gas to elucidate the pollutant-removal efficiency for different inlet and exhaust locations and outdoor air-supply ratios. The wall inlet exhibited a higher pollutant-removal efficiency, owing to the upward movement of the air from the lower zone to the upper one. In conclusion, it is recommended that a total air-conditioning plan for isolation rooms be established as well as efficient system operation for pollutant removal and air-flow control to prevent the transmission of infections from the patients to others.

The demand for radiant cooling systems is increasing deamatically as the standard of living continues to improve. Especially, because of characteristic of heat transfer as cooling air comes down and warm air goes up, radiant cooling system beneath ceiling is more profitable than others system. The characteristics of heat transfer in the radiant cooling system beneath ceiling was investigated in use of simulation program. The radiant cooling system is intervened on air capacity and temperature. There are the variable numbers of air temperature and air velocity According to the results of thermal performance analysis simulation for cooling system beneath ceiling, control of cooling air temperature is more effective than control of its velocity.

Objectives: The purpose of this study is to review the trend of chinese clinical studies of herbal treatment for infertility caused by Polycystic Ovary Syndrome (PCOS). Methods: We searched the clinical studies published from `` to ;0`` through CAJ (Chinese Academic Journal) with keywords of “PCOS and 不孕” or “多囊卵 巢綜合證and 不孕”. We analyzed the intervention type of clinical studies. In addition, We re-searched randomized controlled trials (RCTs) published from ;00 to ;0``, assessed the quality of RCTs using the Jadad Scale and reanalyzed the intervention type of RCTs. Results: One hundred and seventeen clinical studies were finally selected. Clinical studies of herbal treatment for infertility caused by PCOS increased remarkably after the ;000s in China. Combined herbal medicine and western medicine was used the most frequently. RCTs published from ;00 to ;0`` were fifty. Average of Jadad score of RCTs was ``.;. Combined herbal medicine and western medicine was also the most frequently used as intervention in RCTs. Conclusions: Clinical studies on effect of combined herbal medicine and western medicine for infertility caused by PCOS were mostly published in China. But Quality of studies was generally low. Further research on effect of herbal treatment for infertility caused by PCOS is needed.

With the improvement in economic power and diversification of living patterns, the demands of household energy-consumption devices have changed. The household energy consumption accounts for 20 percent of the entire energy consumption in Korea. Among household energy consumption, electric-power consumption is expected to increase as the number of household energy-consumption devices has been on the rise. The purpose of this work is to investigate the possibility of household energy saving through the "the way of reducing the use hours of devices and their use" as the other energy saving way than "choice of highly efficient devices". To achieve the purpose, this researcher conducted a questionnaire survey with 2,250 households in the country to look into the state of the possession and use of household energy-consumption devices. And we investigate into the energy-saving behavior. The results are as follows. First, A household possessed 16.21 household energy-consumption devices. when we are grouping by energy-saving behavior, there is no difference the numbers of energy-consumption devices. Two, group 1 can save energy-cost about 11,000won in the winter and 15,000won in the summer by energy-saving behavior.

The purpose of this study was to find out the present condition of indoor thermal environment and to investigate the environmental needs of olds with the measurement of physical thermal environment elements-floor and indoor temperature, relative humidity, air velocity, and globe temperature, and the questionary survey of the response to thermal environment in a welfare facility for the aged during summer of 2001 in Daegu. The 38 residents among the total of 240 residents were asked to record their feelings. The result of study was as follows; The indoor thermal environment in the facility subjected for this study was seemed to be comfortable comparatively. But the indoor thermal environment in welfare facilities for the aged during summer needed not only to be controled with the cooling equipment but also to ventilate appropriately for keeping the indoor air quality freshly.

As the korean economy and society continue to develop, the cumber of underground commercial spaces are expected to increase. This increase will demand greater heating and cooling energy as well as a sharp rise in overall energy consumption. This study was aimed at the development of energy conservation and analyzed for 2 underground commercial spaces. This study shows the information, that is, tables, graphs and charts as possible of the trend in energy efficiency in underground commercial spaces between 1999 and 2001.6. We suggested the practical application for energy conservation methods and efficient energy use which was based on the investigations and analyses.

This study applied fuel cells, photovoltaic heat, and geothermal heat, some of new and renewable energy sources, to public office facilities in a complex way, evaluated their economy, environmental effect, technology, and complexity, and calculated a payback period by reflecting changing nominal discount rates to the optimal ratio based on complexity. The research content was summarized as follows: 1) The study tested the reliability of annual energy consumptions of the subject building by the load based on EnergyPlus and the calculations based on the KRESS program with MBE and Cv(RMSE). 2) The optimal ratio of top 5% was obtained with KRESS based on the economy, technology, environmental effect, and complexity of photovoltaic, geothermal, and fuel cell systems. 3) The percentage of fuel cells had big impacts on economy and complexity; that of geothermal heat did on technology; and that of photovoltaic heat did on environmental effect. 4) Every 2% increase of nominal discount rate(NDR) led to an increase of payback period by 3 to 7 years for each alternative. The study also presented a relational expression between NDR and payback period.
