Previous research on online games has suggested that virtual world activities improve problem solving and interpersonal skills, but FPS and MMORPG are not well distinguished in various monomeric and difficult activities. The reason for this is that qualitative considerations of activities in the virtual world have not yet been made. Therefore, Tom Clancy's Rainbow Six-Siege, one of the most popular FPS in Japan, focused on the difficulty of supporting groups, and participated in observation and interviews to investigate the quality observation and interviews. The results showed that the first high-difficulty quest requires problem-solving skills and interpersonal skills in an environment where most of the nonverbal information is blocked. Second, it is important to extract players' thoughts and actions from high-difficulty quests, and to identify problems, confirm evidence and facts, propose causes and solutions, and to work together with coordinated actions and harmonious actions. Furthermore, it has been found that these capabilities are provided as two important leadership functions in actual collective work.

Hydraulic conductivity is an important parameter, representing permeable property of the groundwater in aquifers, in the issues of groundwater development, groundwater contamination, and groundwater flow, etc. We estimated a relationship between hydraulic conductivity and electrical properties (formation factor, chargeability, and time constant) of silty sand in the laboratory. For this study, we conducted grain size analysis, constant head permeameter test, and measured electrical resistivity and spectral induced polarization of silty sand samples collected from the riverside alluvium of the Nakdong River in Nogok-ri area, Dasan-myeon, Goryeong-gun in Gyeongbook Province, Korea. In the laboratory test, we used soil samples of approximately uniform porosity with 0.5% error range, and kept the electrical resistivity of pore water with 100 ohm-m. As a result, the relationship between effective particle size and hydraulic conductivity agrees fairly well with the existing empirical formulas. Hydraulic conductivity was correlated with formation factor, chargeability, and time constant: hydraulic conductivity increased with increasing formation factor and time constant as well as with decreasing chargeability.

We estimated the hydraulic conductivity of the sediments using constant-head permeability tests and electrical resistivity measurements with Jumoonjin standard sand of a uniform size and glass beads of different grain sizes. In this study, we determined the variations of the porosity, the hydraulic conductivity, and the resistivity in case 1 (changing the packing of the Jumoonjin standard sand) and in case 2 (varying the size of the glass beads). The results of case 1 showed that the hydraulic conductivity decreased with an increase in the electrical resistivity. This occurred because the sand grain while packing became rhombohedral with the a decrease of both the pore size and porosity. The results of the case 2 showed that the hydraulic conductivity increased due to the increase in the pore size as caused by the increased glass bead size. In addition, the porosity decreased and the electrical resistivity increased. Therefore, the relationship between the hydraulic conductivity and the electrical resistivity is negatively proportional as regards the grain packing with a change from cubic to rhombohedral whereas this relationship is positively proportional to the increase in the grain size.

Objectives : The cardiorespiratory fitness including maximal oxygen uptake(VO, max) in diabetics is generally known to be low, but it is also reported to vary depending upon the type of diabetes mellitus and presence or absence of complicating coronary heart disease and/or cardiovascular autonomic dysfunctions. The purpose of our study is to assess cardiorespiratory fitness and energy metabolism at maximal exercise in non-insulin dependent diabetics without these complications. Methods : Symptom-limited maximal exercise tests by Bruce protocol were carried out in 28 non-insulin dependent diabetic men with neither clinical cardiopulmonary diseases nor cardiovascular autonomic dysfunctions and in 103 matched controls. Comparisons of HR max, VO2 max and their derivatives, and respiratory exchange ratio(RER) and energy expenditure(EE) were made between the diabetics and the controls. In addition, the correlations of RER and EE with the various body characteristics including age were computed. Results: The mean of various parameters reflecting cardiorespiratory responses to maximal exercise and indices of energy metabolism such as RER and EE showed no significant differences between the diabetics and the controls. However, the EE at maximal exercise in the diabetics was significantly inversely correlated with the age alone(r=-0.61, p<0.001), whereas in the controls, it showed a slight negative correlation with age(r= -0.37, p<0.01). Conclusion: These findings suggest that cardiorespiratory fitness level and energy metabolism at maximal exercise in non-insulin dependent diabetic men unaccompanying cardiovascular diseases and autonomic dysfunctions are essentially similar to the normal controls. Nonetheless, the fact that the EE at maximal exercise is highly correlated with the age in the diabetics may be of value to be considered in exercise prescription for these patients.

The purpose of this study was to investigate the factors affecting the succession of small-sized enterprises based on the data of 2015 Market, Shopping Street and Store Management Survey conducted by the Small Enterprise And Market Service(SEMAS). This study was intended to find out whether sales, maintenance period, inherited business, three costs (labor cost, raw material cost, rent fee) have an effect on succession intention of small-sized enterprises by using logistic regression. The result showed that sales, maintenance period, and inherited business positively influence the possibility of succession intention while rent fee negatively affect outcome variables. Further analysis was conducted about whether sales, maintenance period, and the three cost factors have influenced on the consensus about re-succession intention by using logistic regression. The result showed that sales and duration period positively influence increasing the re-succession intention, but only the rent fee negatively influence decreasing the possibility. Based on the results of this study, implications and future research were discussed.

It is necessary and important for professors to activate students' participation in a massive class at a university, because it can't insure the success of a university class without participation of students. In this critical mind, this study is to survey of teaching methods which activate students' participation. Every researcher of this study suggest one or two teaching methods to activate students' participation and discuss concrete application in a massive class and strength and weakness of each suggested method. They are question and answer, cooperative learning, discussion, class using cell phone, symposium, talk show, discussion using ICT. The suggested teaching methods have respectively their own strength and weakness. Therefore it is important to select appropriate methods according to the goal and characteristics of the class. It can be helpful to use some methods together to activate students' participation in a massive class.
