Global construction projects manifest more risks than do other industries. Often, firms doing business in construction markets find these risks intimidating. To secure corresponding profits, many global contractors attempt to forecast the effects of risks and establish risk management strategies. However, one key problem with present-day risk management methods is that they are basically analytical or mathematical-oriented approaches which are not easy to adopt in real business. Based on preliminary investigations and evaluations of current tools, this research elicits more practical algorithms for risk checklist by constructing risk scenarios over the whole period of project execution. For the application of the algorithms, a "SE/RF" (Source-Event/Regular-Floating) checklist is suggested, which sorts out risk sources and their subsequent events, as well as dividing various risk factors into either regular or floating categories. In addition, the "PIS" (Probability-Impact-Significance) method is introduced, in place of traditional "PI" (Probability-Impact) methods, by adding the additional criterion of "risk significance" to determine the degree of risk exposure in a more realistic way. As a result, we draw the significant finding that the "PIS" method presents a closer evaluation regarding degree of risk exposure as compared to the level of expert judgments than those from traditional methods. Finally, we provide an integrated procedure for international project risk management with all of the research achievements being incorporated.

We attempted to evaluate the effectiveness of cold blood potassium cardioplegia [Group B] compared with that of intermittent aortic cross clamp with topical hypothermia [Group A] in each six dogs. The studies were performed under the extracorporeal circulation with moderate hypothermia by using Mongrel dogs. 1. In Group A [6], it was difficult to maintain the temperature below 20?. but in Group B [6], it was possible to maintain the temperature. 2. In blood pressure and myocardial recovery ability, Group B was more excellent than Group A. 3. There was no significant difference in Na+, Ca++ and Cl- between both groups, but in K+ level, Group A was mild decreased and Group B was nearly normal level. 4. In serum LDH level, Group A was higher than Group B, but in SGOT level there was no significance between both groups. 5. On electromicroscopical study, Group A showed severe change in mitochondria, but Group B was nearly normal view. Thus we suggest that cold blood potassium cardioplegia would be more effective than intermittent aortic cross clamp with topical hypothermia for myocardial protection in open heart surgery.

The present study aimed to survey doctors working in five university hospitals about internal customer satisfaction and organization commitment level in order to identify casual relationships through structure equations. According to the analysis, organization management had the biggest impact on internal customer satisfaction level, and the sooner the factor was named personnel, leadership, job, and compensation, the bigger the impact it had on the level. The research model was generally found to be good in terms of goodness of fit, considering the value of $x^2$ calculated as 103.314, the degrees of freedom of 38, GFI 0.924, AGFT 0.868, NFI 0.888, CFI 0.925, and RMSEA 0.086. In conclusion, the internal customer satisfaction level of doctors was significantly proportionate to organization commitment by means of their general satisfaction level, while also being directly proportionate to organization commitment (p<0.05). Meanwhile, statistical significance could not be found when measuring the effects of the doctors' basic characteristics on the levels of internal customer satisfaction and general satisfaction in hospitals.

The landscape of the education market is changing. As part of efforts to deal with the decrease of a school-age population in Korea, Korean universities and colleges are endeavoring to attract foreign students. Chinese students, the largest share of foreign university students in Korea, are becoming an important element at Korean universities and colleges. Chinese students face various kinds of difficulties while trying to cope with new environments in the country. This study aims to analyze the impact of academic factors and psychological factors of Chinese students on the level of adaptation to university life and their satisfaction with it. Data on 128 Chinese students attending D University located in Busan were collected and a path analysis was conducted using partial least squares (PLS) regression. Research results are as follows. First, professors as an academic factor and the level of interest of university staff have significant impact on the level of adaptation to university life while Korean language proficiency does not have significant impact on the level of adaptation to university life. Second, homesickness as a psychological factor is correlated to the level of adaptation to university life with significance while acculturative stress is not correlated to it. Third, the level of adaptation to university life is correlated to the level of satisfaction with university life. Based on these findings, the significance, limitations and future directions of this study are discussed.
