  • Purpose: The purpose of this study was to identify the relationship between spiritual well-being, depression and life satisfaction majoring in human service area. Methods: The subjects were 212 college students. Data was collected from september 15 to October 26, 2009 using questionnaires. Means with standard deviation, t-test, ANOVA, and Pearson correlation coefficients were used to analyze the data. Results: According to general characteristics of the students, there were statistically significant differences in spiritual well-being for religion and religious influence, in depression, there was statistically significant difference for health status, and in life satisfaction, there were statistically significant differences monthly pocket money, health status, current survival parents status, current problem. significant correlations were seen between spiritual well-being and depression (r=-.386, p =.000), life satisfaction (r=.536, p =.000). Conclusion: Spiritual well-being was significantly effects on depression and the life satisfaction. The finding suggest that it is needed to develop effective programs to improve spiritual well-being for college students.

  • The relative importance of single-shot kill probabilities, rates of fire, weapon allocation strategies, and the size of initial force in warfare between two force with heterogeneous multiple weapon systems are considered by examining their effect on a natural measure of effectiveness, the expected number of survivors. Attrition equations are derived via stochastic formulation to represent the mean course of battle having an underlying probability distribution. It is assumed that each side uses indirect area fires. Level of intelligence activities are reflected in the availability of spontaneous information on the current enemy status. Depending on the availability of the information on the current enemy status, each participatory unit may follow 1) a prescribed attack pattern (fraction of the available units assigned to various enemy targets) or 2) an adaptive attack pattern depending on the enemy status at that time. Conditions for possible stalemate are discussed.

  • Regarding the implementation of ROMM project (Rehabilitation, Operation, Maintenance & Management), which is one of overseas development projects, it is very important to diagnose the exact current status of aged thermal power plant. However, when people visit the power plant for the purpose of prediagnosis to implement the ROMM project, most target power plants for diagnosis, in general, are under operation. This can be a big interference factor to diagnose the exact current status of power plants. Therefore, in order to solve such interference factor, based on the 30 years of know-how in the field, the present study has developed a regression curve for a simple life time assessment and the calculation of rehabilitation cost that may be used as a reference relatively for the quantitative diagnosis on the status of a relevant power plant even during the operation of the power plant.

  • This study has been conducted to propose an optimal design guidance of underfloor air distribution system by examining air pattern and proper exhaust status of floor plenum using CFD (Computational Fluid Dynamics). Simulation shows deficient air pattern and exhaust status at BPG (Bypass Grille) of the current design. As a means to find an alternative design, four cases have been developed and tested. Case 1, 2 and 3 show similar results in comparison to the current design. However, case 4 shows improved air pattern and exhaust status at BPG(Bypass Grille), and has been chosen as the optimal alternative.

  • Facilities are getting more automated and informative in modern manufacturing systems, especially in semiconductor and LCD plants. These systems keep a great deal of such information on its current and near-future status as the arrival time and job completion time of their parts. This paper presents an efficient policy for AGV and part routing using information on the future status of the system where AGVs are playing a central role for material handling. Efficient control of AGVs is very important because AGV systems often become the bottleneck and limit the total production capacity of a very expensive plant. The cell controller records the future events chronologically in Next Event Schedule, and uses this list to determine to which place the AGVs and parts to be sent.

  • Using survey data from 323 families headed by the unemployed this study investigated the characteristics of the current living status and their coping strategies according to their job status(blue or white color) Descriptive statistics t-test and chi-square test were used to analyze the data. The results revealed that families headed by the unemployed have been experiencing economic hardship hardship in housing and problems of family functoning as well as decreased level of living. The effects of unemployment were various depending upon the job type of head of the family. The family utilized several positive coping strategies to reduce financial hardships of the family Discussions and recommendations for the future research and practical welfare policy implication s for the families are identified.

  • The purpose of this study is to explore the status of current ICT convergence technology in the agrifood area through reviewing articles. For this, we classified the ICT convergence technology into four categories including RFID technology, smart sensing technology, USN technology, and other ICT convergence cases and reviewed by extracting the cases related to the convergence technology that is recently conducted depending on each category from the Journal of Computers and Electronics in Agriculture between January 2012 and June 2014. Additionally, by combining the reviews of cases, we conducted the study in the direction of analyzing the recent ICT convergence technology status in the current agrifood area.

  • This paper investigated the qualitative introduction status of domestic major construction company. And that focused on a point of suggestions about CM at Risk introduction. The survey analysis showed that three importan suggestions. First, the biggest obstacles factors to CM at Risk introduction that related laws is lagging amendment. Second, we have to improve the available hands ability in domestic major construction company. And last, we have to do that using uncomplicated design and standard design form. Consequently, environmen analysis for the introduction and example project is urgently required.
