Purpose and methods: The purpose of this study was to find out the effect of environmental temperature and humidity on physiological responses during the bicycling exercise (the exercise on a bicycle ergometer). The variables measured were mean skin temperature, rectal temperature, perspiration volume, HR, and VO<sub>2</sub> in each environmental condition of experiment(25℃, 30℃ and 30%, 50%, 70%(RH) 2X3= 6 conditions). The exercise intensity was set at 50% VO<sub>2max.</sub> The subjects were 6 male collegiate students. Results: skin and rectal temperature went up as the environmental temperature and humidity did. The perspiration volume, HR, and VO<sub>2</sub> increased as environmental temperature and humidity went up. Local perspiration of back was much more than that of thigh Conclusion: The physiological responses(rectal temperature, mean skin temperature, perspiration volume, HR, VO<sub>2</sub>) indicated the meaningful difference in proportion to environmental humidity difference under same environmental temperature as well as environmental temperature under same environmental humidity.

Growing importance of online security on certification, many of the web-related security technology introduced day by day. Especially, using smart certificate (USIM) is recognized as one of the most safe and convenient method for the security of public certificate. The purpose of this study is to find the factors that affect the Intention of switching to smart certificate for the general public who use public certificate service. Based on migration theory, this study determined the relationship between pull factors, push factors and mooring factors which can affect the intention of switching to smart certificate. To empirically analyze the proposed hypothesis, the statistical analysis were conducted based on the response from 350 public certificate service users using SPSS 22.0 and Smart PLS 2.0. The results of this study can be summarized as follows. First, system quality, one of the pull factors has positive influence on perceived ease of use. On the other hand, the other pull factor, service quality has positive influence on both perceived ease of use and perceived usefulness. Second, push factors, user experience and information security awareness have positive influence on perceived ease of use only. Third, mooring factor, switching cost does not have influence on switching intention while perceived usefulness has positive influence on. The results of this research can be used for whom has interest to the switching intention of public certificate service for online security and provide the proper understanding about smart certificate service mechanism.

The purpose of this study is to design a computer program algorithm for exercise prescription at fitness center. To fulfill this object, the results of many studies on exercise and health are collected and analyzed. This algorithm makes distinctions among people to differentiate person who can exercise safely at fitness center. For this purpose, several tests were carried out such as par-Q test, Coronary heart disease risk factors, Blood-pressure. They were classified into four groups : hypertension, diabetic, obesity and health group by measuring Blood pressure, blood-sugar and fat mass. And then exercise types were selected and exercise intensity, amount, frequence were calculated for each person in each group. If this algorithm is complemented in some aspects and written a computer program in accordance with that algorithm, it will be used as a good tool in many places where need exercise prescription.
