The induction of chromosome aberrations in Hordeum vulgare germs after irradiation is studied for the dose range of 10 to 1,000 mGy. The relationship between the frequency of aberrant cells and the absorbed dose is shown to be non -linear and has a dose-independent plateau within the range of 56-467 mGy where the level of cytogenetic damage is statistically significantly distinguished from the spontaneous level. The comparison of the goodness of the experimental data fitting with mathematical models of different complexities, using the most common quantitative criteria, demonstrates the benefit of the piecewise linear model over the linear and polynomial ones in approximating the cytogenetical disturbance frequency. The results of our study support the conclusion about indirect mechanism of chromosome aberrations induced by low doses or dose rates mutagenesis.

This project has been designed for people to experience and understand the process, importance and benefit of coal fire plants. As the biggest and first typical Korean fire plant using coal, Boryeong fire plant has had important roll for the Korean industries. Even so, people has had wrong prejudice for the fire plant in terms of environmental protection. To do these kind of rolls, this museum has been designed with theme, "Boryeong fire plant mating symbiotic relationship between nature, human and technologies." The space was zoned with five major themes: i. circulation of energy in nature, ii. electric power and eco-fire plant, iii. future energy, iv roll for future of environment, v. Korea as the leading energy industry. The design has been developed focused on spatial experiences to make 'Design Sequence' with linear circulations haying several important destinations. The interior has been finished with minimal color and materials projected by big sized movie and various LED movie system. Concept of appordance has been used to make interactive experiences between exhibits and visitors.

The purpose of this study is (1) to investigate how children's peer interaction type and joint problem-solving performance differ, depending on a partner's age, in such a situation as they are asked to solve problems with their peer and (2) to investigate relationship between children's peer interaction type and joint problem-solving performance. Results reveal that children's problem-solving performance receives more benefit in the interactions with older peers, rather than those with younger ones. It can also be improved by higher level of collaborative interactions such as abstract collaborative explanations in joint activities. It is influenced positively by collaborative interactions, expecially when the children are in the same age groups. Results here were discussed in terns Piagetian and Vygotskian theories.

Police officers' job satisfaction has usually been measured by quantitative methods such as survey. This research is the first attempt to interview police officers in Korea to find how satisfied they are with their job. Based on e-mail interview with fourteen police officers in Korea, the study measured the multiple dimensions of job satisfaction including work condition, relationship with supervisors and colleagues, personnel management, pay and benefit, and discretion. The results suggested that police officers' attitude toward their job and motivation of becoming police officers may influence their job satisfaction. Other findings and policy implications are also discussed.

Epidemiology studies indicate that diet or specific dietary components can reduce the risk for cancer, cardiovascular disease and diabetes. An underlying cause of these diseases is chronic inflammation. Dietary components that are beneficial against disease seem to have multiple mechanisms of action and many also have a common mechanism of reducing inflammation, often via the $NF{\kappa}B$ pathway. Thus, a plant based diet can contain many components that reduce inflammation and can reduce the risk for developing all three of these chronic diseases. We summarize dietary components that have been shown to reduce cancer risk and two studies that show that dietary walnut can reduce cancer growth and development. Part of the mechanism for the anticancer benefit of walnut was by suppressing the activation of $NF{\kappa}B$. In this brief review, we focus on reduction of cancer risk by dietary components and the relationship to suppression of inflammation. However, it should be remembered that most dietary components have multiple beneficial mechanisms of action that can be additive and that suppression of chronic inflammation should reduce the risk for all three chronic diseases.

The importance of Information technology (IT) has been growing. Thus, it is critical for firms to choose the optimal information technology development mode in order to ensure that maximum benefit is derived from IT. Despite its importance, however, there is little comprehensive research on choosing the IT development mode that firms undertake. To fill this gap, this study attempts to propose a parsimonious as well as comprehensive IT development framework based on strategic value and the uniqueness of IT resources. In addition, this study analyzes the impact of the fit between the theoretically proposed IT development mode and the actually used mode on the performance of Korean firms. This study contributes to and expands the literature on IT development modes by considering various development modes in real time. Moreover, the results serve as a stepping stone for managers who want to develop or adopt IT effectively.

This paper examines how online product information changes the customers' purchase intentions from subjectivity-objectivity dichotomy perspective. Quality and Preference are proposed as product evaluation criteria and their marginal changes with product information differentiation are hypothesized. An experimental survey was conducted to 57 subjects and the hypotheses were partially supported through PLS path comparison method. The study contributes to IS research by proposing a simple and effective product evaluation framework and by abstracting the impact of product information from other factors. Finally, we suggest the utilization of product information with the optimization of the cost-benefit structure between information and purchase intention.

To improve maritime security and enhance international shipping commerce within US ports in addition to ISPS (International Ship and Port Facility Security Code), the TWIC (Transportation Worker Identification Credential) program is working on the maritime field from the October 15, 2008 in the United States. In this paper, the program is reviewed and investigated in terms of goal, benefit, solution, and related legislation so forth In addition, other maritime security programs including MMD (Merchant Mariner Document), FAST (Free and Secure Trade), SIDA (Security Identification Display Areas). and Air Cargo security program was analyzed and compared in order to obtain relationship and difference with the program in terms of enrollment frequency, list and method of security check, and profile of each program As a result of this paper, the program is mostly to improve maritime security, protect individual privacy, and enhance commerce rather than other programs.

With the advent of the Internet era, most industries are actively taking part in the web-based electronic commerce markets. To come up with the trend, Korean shipping companies have built their own websites and tried to take advantage of the state-of-the-art technology. This paper aims to analyze recent developments in e-commerce of shipping industry and, Also the study suggests several solutions to invigorate the virtual transactions. To analyze recent developments, this paper carries out a cases study on the websites of 5 major shipping companies in Korea. Each sites are evaluated with respect to 4C's(Contents, Commerce, Community, Connection) analysis.
