This study examined the positive impact of workplace harassment on the employees' counterproductive work behavior at deluxe hotel in Seoul and Tokyo. The study verified a differentiated influence based on the nationality of the employees. The hypothesized relationships in the model were tested simultaneously by using structural equation modelling. First, isolation/exclusion (${\beta}=.403$), disrespectful behavior (${\beta}=.312$), physical aggression (${\beta}=.245$), and verbal aggression (${\beta}=.133$) had a positive impact on counterproductive work behavior. However, threats/bribes (${\beta}=.091$) did not show a significant impact. Second, no significant moderating effect based on employees' nationality (Korean versus Japanese) was observed in the relationship between the five workplace harassment factors and CWB. This study will investigate workplace harassment perceived by deluxe hotel employees in Korea and Japan, and the obtained data can also be used to help identify realistic plans to reduce workplace harassment between bosses and subordinates at an organizational level.

Currently the problem of air pollution caused by the motor vehicle emission is one of the most serious problems to be solved. Thus we needed the vehicle emissions audit procedure and technical innovation constraining the motor vehicle emission. The Korean Environmental Protection Agency currently audits automobiles for emissions compliance at assembly plants with multiple attribute multiple staged sampling plans. In order to establish the more reasonable audit procedure, the multiple staged sampling plan designed in this paper has been applied to the domestic vehicles by analyzing the statistic characteristics of the emission distribution. This paper summarizes the auditing procedure and develops methods for determining its statistical characteristics. Specifically, we consider how to evaluate a multiple staged sampling plan, give a procedure that efficiently estimates attribute-type probabilities from multivariate variables-type data, and quantify the effect of tightening the acceptable quality level of the sampling plan. As a result it can be proved that this audit procedure is the reasonable plan minimizing the AQL (Acceptable Quality Level) and is to be used effectively for the auditing procedure constraining the injurious gasses of the motor vehicles.

Mortality study is an essential component of actuarial risk management for life insurance policies, annuities, and pension plans. Life expectancy has drastically increased over the last several decades; consequently, longevity risk associated with annuity products and pension systems has emerged as a crucial issue. Among the various aspects of mortality study, a consideration of the cause-of-death mortality can provide a more comprehensive understanding of the nature of mortality/longevity risk. In this case study, the cause-of-mortality data in Korea and the US were analyzed along with a multinomial logistic regression model that was constructed to quantify the impact of mortality reduction in a specific cause on actuarial values. The results of analyses imply that mortality improvement due to a specific cause should be carefully monitored and reflected in mortality/longevity risk management. It was also confirmed that multinomial logistic regression model is a useful tool for analyzing cause-of-death mortality for actuarial applications.

Spread of internet service had a huge effect on usage and spread of SNS world widely. Variety of the service has increased from human network managing to commerce, education, payment method and so on. Also, it is expanding its service territory to not only PC area but also that of mobile equipment with development of information technology. Spread of use on SNS provides existing corporations the expansion of service area. Late SNS starter companies are advancing in diverse way for attracting users by serving shopping, games and other services with association with SNS. Therefore, analysis on consumers' thought and pattern which analyze users' demand, service's function and contents and other factors in order to reflect on plans and operations of SNS is needed. On this perspective, this research is suggesting properties that are crucially related to sustained usage of SNS and study factors of SNS's characteristics that influence trust and satisfaction on SNS and continuous usage intent of SNS.

The purpose of this study was to develop a standardized scale to diagnostic life planning in late adolescence. A preliminary 32 item scale was developed through a literature review & a survey. 896 people responded to an online survey using the preliminary scale. A series of test, such as test-retest, item-to-total correlation, factor analysis and Cronbach' ${\alpha}$ reliability were conducted using the survey data and a scale comprising 31 items was constructed finally. The diagnostic scale for life planning in late Adolescence consisted of seven factors : (1) complete growth minds (2) life- plan (3) variety experiences (4) close relationships (5) management of healthy body (6) practical finance-plans (7) active preparation of future job. The scale is useful as a guideline for managing life of the late Adolescence. And it is helpful to them to make plan for the better life.

The purpose of this study is to examine support policies regarding work and family reconciliation, to suggest plans to improve workplace policies, and to suggest directions for further studies. This study looks at OECD's work-life reconciliation policies as well as family friendly workplace policies in Korea to find a way to enhance business' receptiveness and implementation of the policies. By examining women's labor conditions, this study finds that family friendly workplace policies are necessarily imminent in our society of low fertility and ageing. Along with the evaluation of benefit level and the effectiveness of current policies, this study uses data from interviews with working mothers who have had the experience of family friendly benefits. The results of the analyses suggest that the government should focus on improving the workplace environment in companies that do not show bias against the use of family friendly policies. In order to farm more successful policies, future studies are needed to analyze the changes of fertility, working conditions, support programs, and benefits.

Construction Performance measurement and management has been interested by construction practitioners. However, current construction project management practices are related to short-term improvement plans rather than long-term and systematic approaches based upon performance analysis. AR a result, there is a need for developing of a collaborative plan over project life cycle. Therefore, this paper reviews extensive literature and proposes the construction performance estimating model using a system dynamics. The paper proposes casual maps for planning, design, procurement, and construction phases. Each casual map includes all performance indicators and factors that impact on performance directly or indirectly. These casual maps that were developed by system thinking will enhance the understanding of the relationships among performances and factors. After further data gathering, these models can be used to estimate construction performance and eventually these will save project costs and shorten project schedule.

This study aimed at the introduction of desktop method for assessment of environmental flows developed by IWMI(International Water Management Institute) recently and its application to Geum river basin. This scheme simulated the influence on aquatic ecosystem caused by watershed development and in turn the decrease of water quantity keeping the river's own flow regime. It was found to be as very effective method although it had simple structure. Flow duration curves for different environmental classes at Sutong and Gongjoo sites were estimated according to the natural conditional scenario of Geum river basin and the results were relatively compared well with the previous studies. The behaviors of monthly average runoff time series of both sites showed the level of A class. The results of this study would provide the fundamental data to establish the future plans of monitoring or management for aquatic ecosystem of Geum river basin.
