  • The types and quantities of Hazmat and Hazmat transportation are gradually increasing, keeping pace with industrialization and urbanization. At present the safety management for Hazmat transportation only considers reducing accident probability, but even when an accident involving Hazmat-carrying vehicles occurs, that is not regarded as a Hazmat-related accident if the Hazmats do not leak out from the containers carrying them. Thus the methods to reduce risk (Risk=Probability$\times$Consequence) have to be developed by incorporating accident probability and consequence. By using Geographic Information System (GIS), a technical method is invented and is automatically able to evaluate the consequence by different types of Hazmat. Thus this study analyzed the degree of risk on the links classified by the Hazmat transport pathways. In order to mitigate the degree of risk, a method of 7-step risk management on Hazmat transportation in railway industries can be suggested. (1st step: building up GIS DB, 2nd step: calculating accident probability on each link, 3rd step: calculating consequence by Hazmat types, 4th step: determination of risk, 5th step: analysis of alternative plans for mitigating the risk, 6th: measure of effectiveness against each alternative, and 7th step: action plans to be weak probability and consequence by the range recommended from ALARP). In conclusion, those 7 steps are used as a standardization method of optimum transportation routing. And to increase the efficiency of optimum transportation routing, optional route can be revise by verification.

  • The purpose of this study examined the differences in work-family spillover process and domains in dual-earner couples with children, using a multidimensional measure of work-family spillover. The subjects of this study were 285 working couples with children. The research tool was questionnaires which consisted of general characteristics of the subjects and multidimensional measure of work-family spillover scale. For data analysis, factor analysis, Cronbach ${\alpha}$, t-test, and paired t-test were performed. Based on analysis of data using factor analysis, three-distinct work-family spillover process can be measured for both wife and husband, time interference, psychological distraction, and energy depletion and the multidimensional measure of work-family spillover is able to validly assess different domains of family life into which spillover occurs. The main results of this study were as following: First, there were significant differences in work-family spillover process according to sex. In work${\rightarrow}$family spillover, male more experienced negative time interference than female, on the other hand, in family${\rightarrow}$work spillover, female more experienced negative energy depletion than male. Second, there were significant differences in domains which work-family spillover occurs according to sex. Male more experienced negative work${\rightarrow}$family spillover than female in marital relations and parent-child relations domains while female more experienced negative family${\rightarrow}$work spillover than male in parent-child relations and home management domains. Third, there were significant differences between wife and husband in work-family spillover process. In work${\rightarrow}$family spillover, husband more experienced negative time interference than wife, on the other hand, in family${\rightarrow}$work spillover, wife more experienced negative energy depletion than husbands. Forth, there were significant differences between wife and husband in domains which work-family spillover occurs. Male more experienced negative work${\rightarrow}$family spillover than female in marital relations, parent-child relations, and leisure life domains. And while husband more experienced negative family${\rightarrow}$work spillover than wife in parent-child relations, wife more experienced negative family${\rightarrow}$work spillover than husband in home management domains.

  • Purpose: The purpose of this study was to investigate the effects of an integrated management program on climacteric symptoms and depression in middle-aged women. Methods: A nonequivalent control-group design was used. The subjects consisted of 65 middle-aged women with climacteric symptoms. The experimental group (n=33) participated in the program for six 60-min sessions. To measure the climacteric symptoms and depression level of the subjects, two self-reporting questionnaires were used. Data were analyzed using SPSS Statistics 17.0 program. Results: The women in the experimental group reported the average score of 13.80 in climacteric symptoms, 14.38 in depression. The hypothesis that the climacteric symptoms of experimental group would be reduced more than that of the control group was supported (t=3.92, p<.001): physical symptoms (t=4.04, p<.001); psychological symptoms (t=1.80, p=.077); sexual symptoms (t=2.85, p=.006). The second hypothesis that the degree of depression of the experimental group who used the integrated climacteric symptoms management program would be reduced more than that of the control group was also supported (t=2.30, p=.02). Conclusion: The integrated management program for middle-aged women with climacteric symptoms was effective in reducing their climacteric symptoms and depression level.

  • This study examines whether expenditures in information technology (IT) are associated with increases in Tobin's q ratios, a measure of management performance, in the banking industry. The association between IT expenditures and Tobin's q ratios is different, depending upon the banks' size (national vs regional) and strategic orientation (wholesale vs retail), in the Korean commercial banks for the period studied 1990-1996, For national commercial banks which have more clients and electronic banking systems than regional banks, IT expenditures appear to increase Tobin's q ratios. This may indicate that IT is linked to the ability to achieve economies of scale or network effects when large banks use IT as a strategic tool. The association between IT expenditures and management performance measures is also positive and statistically significant for retail-oriented banks. This research makes two important practical contributions with respect to financial reform. First, the evidence suggested that Korean commercial banks need to apply IT strategy in conjunction with restructuring strategy to be a super-bank and, hence, reap substantial competitive advantage from IT applications. Second, since the government recently encouraged commercial banks to increase credit loans as a means of financial reform, most banks tend to focus on retail banking. IT used in the retail banking sector contributes to improve management performance as the evidence suggested.

  • In Korea, the road transport industry is pointed out as a major cause of air pollutants, so management control is needed. Existing studies used only positive input and output variables to measure regional efficiency. However, it is necessary to consider the environmental pollution problem in efficiency analysis. In this study, an undesirable SBM analysis using CO2 was conducted to measure efficiency of domestic regions. In addition, SDM was conducted to examine the ripple effect between domestic regions. As a result of the analysis, the efficiency of the capital area such as Seoul, Gyeonggi, and Incheon was high in the road transport industry. However, the efficiency of the road transportation industry in Daegu and Gangwon was low. In the SDM analysis, it was found that the regional equipment capabilities had a great influence on efficiency. In order to improve efficiency, it is necessary to increase and improve the equipment capacity of the road transport industry.

  • Recent concerns over national and corporate competitiveness have stimulated a renewed interest in organization's performance. The organization's performance primarily depends on resources including human resources, budget, physical based resources, and so on. Especially because the relationship between organization's performance ;md individual capabilities is more evident in R & D organizations where the knowledge base is embodied in people, there has taken an increasing interest in the methodologies for measuring the capabilities of R & D personnel. This paper presents new methodological approach to measure the capabilities of R & D personnel. And the model is empirically applied to ETRI, a public R & D organization in Korea. On the basis of the results, the implications for R & D management are discussed, with regard to R & D business and human resources management.

  • Forest roads failure is one of the most common problems caused by heavy rainfalls. This study investigated the characteristics on stabilization measures installed for cutting slopes failure of forest road resulted from heavy rainfalls. Three primary factors (slope length, slope gradient, soil type) affecting cutting slope failure were considered and stabilization measures were classified into two types (A type: wooden fence, vegetation sandbag, stone masonry; B type: wire cylinder, gabion, concrete retaining wall) through discriminant analysis based on their capacity of resistance to slope failure. Results showed that A type was mainly installed in such conditions as cut slope <8 m, cut slope gradient $30-40^{\circ}$ and soil type with soil while B type occurred in locational conditions as cut slope length >8 m, cut slope gradient < $30^{\circ}$ and > $30^{\circ}$, and soil type of gravelly soil and rock.
