This study aims to examine the status and problems of trade risk management of Korean companies in Incheon area trading with China and to suggest some improvement measures. On the survey with twenty five questions on company profiles, business process and transactions, claims and trade risks, etc. with Chinese trading partners, the following facts are found. In general, Chinese policies on foreign trade, finance, labour, investment, etc. and China's logistics system have caused great worries to Korean companies in Incheon area. This kind of risks from Chinese government policies and China's economic structure are beyond control of each company. Korean government should take more effective measures to negotiate with Chinese government. In the stage of contract, procurement and transportation, settlement, disputes resolution and etc. Korean companies in Incheon area also have many problems with relatively high risks with Chinese trading partners. Based on these survey results, some suggestions for better trade risk management are given.

There has been a lot of researches on the major motivation of consumer's choice for airlines. Due to the competition in airline industries, most of airlines offer a various level of benefits to customers such as a frequent traveller bonus, a schedule, services in flight including a meal and an entertainment program, a discounted fare and an intangible part of personal service. However, it is very difficult to measure the performance of the customers' benefit and to identify the weight of each factor being considered on the airline choice. In this paper, we focus on the airline choice process for the business travellers. The AHP is applied to evaluate the factors reflecting the business travellers' choice for airlines. This study will be useful to build a marketing plan for the business traveller's market.

Experimental study was carried out to investigate the structural performance of composite beams with steel fiber concrete and angle. For this purpose, seven specimens composed of two RC beams with or without steel fiber and five composite beams with steel fiber and angle were constructed and tested. All specimens had no web shear reinforcement. Main variables for the specimens were tensile reinforcement ratio and fiber volume fraction. Based on the test results, structural performance such as strength, stiffness, ductility and energy dissipation capacity was evaluated and compared with the predicted strength. The prediction of flexure and shear strength gives a good relationship with the observed strength. The strength, ductility and energy dissipation capacity are increased, as the fiber volume fraction is increased. Meanwhile, high tensile reinforcement ratio resulted in the reduction of ductility and energy dissipation capacity for the composite beams.

Recently, Korea brings to remarkable levels about industrialization, modernization, population and development of technology. Especially, the rapidly growing from this technology has increased the burden on existing industrial waste landfills. The purpose of this research is to existing knowledge base of landfill cover liner behavior during periods freeze/thaw. Although these tests have been invaluable in clarifying the problem of freeze/thaw, extending the results of such experimental studies to prototype landfills are questionable. For this investigation, the author utilized a large scale laboratory simulation allowing inclusion of the field depth of the cover systems, layered soil profiles, rainfall simulation, a cold climate and boundary conditions similar to those encountered in the landfill. And the soil materials used stabilized soils (mixed clays, cements, and minerals) instead of clays. The bottom liners are made up of drainage layer (30cm), stabilized layer (75cm), and leach collection layer (60cm). The stabilized layers are made up of supporting layer (45cm) and impermeable layer (30cm) - consisted of $P_A$ and $P_B$ layer.

The purpose of this study was to investigate preservice elementary school teachers' views on the relationship between science/technology and society. Freshmen (n=93) and seniors (n=82) at three universities of education were asked to express their views with 8 items in the Views On Science-Technology-Society, which consisted of two subcategories; 'influence of science/technology on society' (4 items) and 'influence of society on science/technology' (4 items). Mann-Whitney U test revealed that the scores of the freshmen were higher than those of the seniors. This trend was notable particularly in the item concerning 'influence of corporations on science/technology' and 'influence of interest groups on science/technology'. In comparing the scores by gender, a significant difference was found in the item concerning 'influence of policy on science/technology' for the freshmen.

Science-related affective domain is considered as a very important domain for achieving students' scientific literacy. Most science educational objectives include some objectives about affective domain such as scientific attitudes, values, curiosity, interests and concerns about nature and science. In this research, the evaluation framework and items of science-related affective domain were developed. The evaluation framework consists of three main categories such as cognition, interest and scientific attitudes and 16 subcategories. The validity of the evaluation framework is tested by ten science educators. Forty-eight items are selected among item pool by considering item response analysis and item-test correlation coefficient. The Cronbach ${\alpha}$ of the tests is 0.83(cognition and interest) and 0.86(scientific attitudes). The results of the test are as follows. First, boys got higher scores than girls. Second, elementary students got higher scores than secondary students. Finally. students in urban areas showed higher scores than those in rural areas.

The recent domestic violence research has emphasized an integrated approach to wife battering and child abuse to overcome separated understanding and problem-solving alternatives of the two phenomena in the past. This phenomenological study is designed to understand struggles and dilemmas of battered women and their children related to their surviving and coping with domestic violence in a mother-child relationship. In-depth interviews were conducted with ten battered women who have children and reside in shelters in Seoul and Anyang, and were analyzed by Atlas.ti(a qualitative software program) to maximize the efficiency of data analysis. Domestic violence can be transformed into and integrated with child abuse anytime, so battered women and their children share their crises and challenges related to motherliness and filial love. However, the mutual, existential meaning embedded in the mother-child relationship can be the most important sources to mobilize their life energy and resilience in their copping efforts. The social work interventions for battered women and their children should be integrated with a premise of deep understanding of the complex realities of domestic violence victims.

Due to the characteristics of 3 ${\times}$ 3 Latin square design which is composed of two block effects and one main effect, powers of rank transformed statistic for testing the main effect are very superior to powers of parametric statistic without regard to the type of population distributions. By order of when all three effects are fixed, when on one block effect is random, when two block effects are random, the rank transform statistic for testing the main effect shows relatively high powers as compared with the parametric statistic. Further when the size of main effect is big with one equivalent size of block effect and the other small size of block effect, powers of rank transformed statistic for testing the main effect demonstrate excellent advantage to powers of parametric statistic.

This study is the result of a fuzzy-AHP-based evaluation of the support policy for the export of Chinese software, for which nine Class 1 evaluation indexes were established. Following a survey of 10 Chinese software experts, fuzzy AHP was used to assess and evaluate the absolute and relative importance of each index. The evaluation revealed that the support policy had relatively positive effects. More specifically, the analysis showed that several indices - technology development, HR development, marketing reinforcement, fund support, platform establishment, and product support - carried relatively significant importance. Quality management and tax deductions, on the other hand, showed no importance, while the importance of international certification was relatively small. In light of these discoveries, there is a need to train experts, increase software quality, and reconsider software brands.

Climate change affects human and natural environment. Many countries, including Korea, are trying to develop climate change adaptation strategies to minimize adverse impacts of climate change. To deal with climate change efficiently, decisions have to be made among many options. The objectives of this paper is to analyzes methodologies for prioritizing climate change adaptation measures. Each methodology has strength and weakness and information requirements are differ. We find multi-criteria analysis is one of useful tools considering current level of understanding on climate change adaptation. We suggest climate change risks(timing, likelihood, intensity of climate change impacts), feasibility of policy (equity, main-streaming, democracy), effectiveness (economic effectiveness, co-benefits, propagation effects) of adaptation measures as main evaluation criteria of prioritization.
