Objective: The aim of this study is to suggest some improvement ideas based on the validity and the reliability analyses of the current safety culture measurement method applied to the Korean nuclear power industry. Background: Wrong safety culture is known as one of the major causes of the disasters such as the space shuttle Columbia disaster or the Fukushima Nuclear Power Plant accident. Assessment of safety culture of an organization is important to build a safer organizational environment as well as to identify the risks hidden in the organization. Method: A face validity of the current safety culture measurement method was analyzed by comparison of the key factors of safety culture in the Korean nuclear power industry with those factors reviewed in the previous studies. The current interview method was analyzed to identify the problems which degrade the consistency of evaluation. Results: Most safety culture factors reviewed in the literatures are covered in the list of the Korean nuclear power industry safety culture factors. However the unstructured questions used in the interview may result in inconsistency of safety culture evaluation among interviewers. Conclusion: This study suggests some examples which might improve the consistency of interviewers' evaluation on safety culture such as a post interview evaluation form. Application: An extended post interview evaluation form might help to increase the accuracy of the interviewing method for Korean nuclear industry safety culture evaluation.

The purpose of this study is to provide basic data needed to examine the relationship between father and son by investigating correlations among male college students' perceptions of the degree of closeness to their fathers their fathers' paternal role and their own paternal role in the future. The subjects of this study were 474 male college students(sophomores juniors and seniors) from Seoul and Daegu. The questionaire the means of this research is composed of classified questions on related studies and on the researches of reference literatures, Statistical methods applied for data analysis were frequencies mean standard deviation Pearson's correlation. Major findings are as follows; 1) When a son perceives that he is on intimate terms with his father he perceives that his father performs paternal role well. Intimate relation between the father and the son can be considered essential to good performance of paternal role. 2)When a son perceives that he is on intimate terms w th his father he believes that he will perform his own paternal role will in the future. That is the son seems to accept his future paternal role positively as he feels close to his father. 3) Male college students who perceive their fathers' paternal role is properly performed tend to believe they will perform their own paternal role well in the future. Judging from the relation between fathers' performance of paternal role and sons' perception of thir future paternal role we can say good performance of paternal role is important is building up sons' affirmative perception of paternal role.

Standing in front of the huge benefits that shipping industry brings about in economy, politics and society of a country, many countries, especially the developing countries have strived hard to invest and develop their shipping industry (if any) by many methods such as economic reform act, tax allowance or even raising capital from domestic and foreign resources which seems very difficult to implement in the 21st century. According to analysis of A. Gerschenkron - a Russian economic historian at around 60 years ago, developing countries, who regarded shipping as an industry of strategic value with multi-dimensional affects for economic development, had utilized their backward advantages and imported modern technology, capital and skillful labor from more advanced countries in the course of fast industrialization in their countries. In fact, Gerschenkron model has applied in shipping industry of many backward countries. Korea's industrialization in shipping analyzed by Tae-Woo Lee (1996) could considered as a good example, in which the country makes use of policies on capital of tonnage finance, ideology, labor management in order to develop the industry. In this paper, the authors try to find the applicability of the Gerschenkron model to the shipping industry in developing countries, especially in Vietnam. And some questions which are necessary for the author's next paper about developing strategies to shipping industry in developing countries will be asked.

The objective of this paper is to evaluate of fisheries competitiveness in Korea, China and Japan. A joint research with researchers from Korea, China and Japan from 2007 to 2008 was conducted to analyze competitiveness of each respective fishery industry. An industry's competitiveness means the aggregated and potential abilities of the infrastructure, producers and other operators in the industry. The study improved the Norway-Iceland Model developed by the FCI Team(2005) and applied it to the fisheries of the 3 countries. To compare competitiveness of each fishery from the 3 countries, the study examined 87 items including 64 questions and 23 statistics items. Korea fisheries' competitive advantage over China is in marketing capability. Capabilities of fishing companies and fishing processors are also slightly over Japan's performance. However, Korea holds an absolute disadvantage over China and Japan when it comes to the macroeconomic environments and government support, industrial environments and infrastructure, and production and management. Korea's fishing companies and fishing processors especially are much weaker than those of China. In conclusion, Korea needs strategies to advance the industry's structure, China needs to expand the industry's base and Japan needs to differentiate the industry.

In every sectors of industry, the Business Process Reengineering(BPR) has been applied for taking competitive advantage under rapidly changing environment. A company adopting the BPR has begun to consider the introduction of Enterprise Resource Planning ERP systems. ERP systems can integrates many core activities of business, such as manufacturing management, human resource management, financial management, supply chain management by applying the best practices to facilitate a rapid decision-making, cost reductions, and organizational control. Unfortunately, however, many tentative risk factors are existed through each phase of the introduction of ERP systems. As a result, it can bring an enormous benefits to a company or it can be a disastrous for organization. Therefore, two critical questions regarding the introduction of ERP systems should be analyzed before actual introduction has happened. They are "how can ERP systems be introduced successfully\ulcorner" and "what are the critical success factors for each phase of introduction of ERP systems\ulcorner". Through this research, We studied and analyzed the characteristics of critical success factors requiring at each phase of the introduction of ERP systems by applying the questionnaire survey method. Finally, we suggest the list of barriers and critical success factors for each phase of introduction of ERP systems.tion of ERP systems.

Water is an indispensable input to human's existence and industrial production. In these days, people are getting more concerned about their health and the interest in the safety of drinking water has increased. In this situation, this paper attempts to measure the economic benefits of the tap water quality improvement. The study area was restricted to Busan, the second largest city in Korea, where local government is planning to implement a tap water quality improvement program. We apply a one-and-one-half bounded dichotomous choice contingent valuation (CV) method to obtain at least a preliminary evaluation of the benefits. CV is developed for valuing goods or services that cannot be valued either directly or indirectly from market observations and has been applied to several environmental goods. The CV survey was rigorously designed to comply with the guidelines for best-practiced CV studies. We surveyed a randomly selected sample of 400 households in Busan and asked respondents questions in person-to-person interviews about how they would be willing to pay for the water quality improvement. Respondents overall accepted the contingent market and were willing to contribute a significant amount (US$1.66), on average, per household per month. We can also calculate the aggregate value of the program which improves the water quality in Busan. This study is expected to provide policy-makers with useful information for evaluating and planning environmental policies relating specifically to water.

One of the unresolved questions in articular cartilage biomechanics is the magnitude of the dynamic modulus and tissue compressive strains under physiological loading conditions. The objective of this study was to characterize the dynamic modulus and compressive strain magnitudes of bovine articular cartilage at physiological compressive stress level and loading frequency. Four bovine calf shoulder joints (ages 2-4 months) were loaded in Instron testing system under load control, with a load amplitude up to 800 N and loading frequency of 1 Hz, resulting in peak engineering stress amplitude of ${\sim}5.8\;MPa$. The corresponding peak deformation of the articular layer reached ${\sim}27%$ of its thickness. The effective dynamic modulus determined from the slope of stress versus strain curve was ${\sim}23\;MPa$, and the phase angle difference between the applied stress and measured strain which is equivalent to the area of the hystresis loop in the stress-strain response was ${\sim}8.3^{\circ}$. These results are representative of the functional properties of articular cartilage in a physiological loading environment. This study provides novel experimental findings on the physiological strain magnitudes and dynamic modulus achieved in intact articular layers under cyclical loading conditions.
