Due to the construction of Incheon Grand Bridge, there is driven a necessity for rearranging the function of Inner Port with the development of Outer South Port. In this paper, I'd like to simulate the port operation levels of Lock Gate in Inner Port with estimating the traffic volumes of 2011 and 2015, which will reveal the Demurrage Cost and the Accumulation Cost of Freight in Inner Port. Finally I will evaluate the economic movement effects of the container ship's calling from Inner port to South Port/Outer South Port from 2011 to 2015. The results are as followings ; (1) The average utilization of Lock Gates are reduced by $7\sim8$ percentage point. (2) The mean queueing value are saved by 25 percentage point. (3) The Demurrage Cost and the Accumulation Cost of Freight except Lock Gate charges and the Benefit of Routeing Reduction are saved about 800 million Won annually.

Agricultural extension programs in Korea had focused mainly on increased production, and the biggest pride of extension was the achievement of rice self-sufficency in 1970s and abundant vegetable and animal production in 1980s. Farming in Korea has changed rapidly in recent years and extension system on commercialized crops have not been satisfactorily developed to mete farmers` demands. Facing the emerging challenges of international competition and trade liberalization for agricultural commodities, the goals of extension should be focused on increased income and the welfare of coral communities. The transfering of agricultural extension educator from central government jobs to local ones has emerged recently under the trends of localization which resulted unstable job environment of extension educator. Intensive pre-service and in-service training of extension workers on current and advanced techologies are essential to upgrade the quality of extension services, and the future directions for professional development of agricultural extension educators in Korea were suggested as follows: 1. Establishing a national network on agricultural extension system to promote exchanges of information among counties and provinces, to conduct meetings and to publish information on agricultural extension. 2. Determining the implications of recent national and global trends on agricultural extension, and strenthening communication at local, national and international levels for an effective extension system in the era of localization, internationalization and globalization; 3. Recognizing the effect of number and quality of extension staff on the impact of extension and providing opportunities development and advancement of extension personnel through education, training, incentives and rewards; 4. Giving a higher priority to agricultural extension in national policies in order to ensure the adequacy of budgetary support and recognition of importance of extension by the ministries concerned and mass communications.

The subjects of ttis study were middle-aged women in their 40s$\sim$50s and older women aged 60 and over who were living in Seoul and Kyonggi-do, Korea. Through studying the participants' responses to the questions regarding the attributes of image preference in terms of the levels of satisfaction and importance, the target consumers' demand has been studied. And, they are applied to a QFD Matrix, to find out the relationship between the attributes of product quality and the guidelines of clothing design. For this study, clothing image preference is categorized as three types: fashionable and urbane image, elegant and formal image, comfortable and active image. It has also been found that middle-aged and older women think the clothing that projects fashionable and urbane image needs more improvement that those for other images. To review demands for the clothing image preference attribute of formal suits for middle-aged and older women, the priority of these attributes through QFD Matrix that shows the relationship between the attributes and dress elements emphasized by designers has been examined. In reflecting clothing image preference by consumers for their formal two-piece suits, the most important design elements related to material in order of importance were material type, style, thickness and texture, and those related to color were the number of colors used and coloring type.

The subjects of this study were middle-aged women in their 40s$\sim$50s and older women aged 60 and over who were living in Seoul and Kyonggi-do, Korea. Through studying the participants' responses to the questions regarding the attributes of apparel quality in terms of the levels of satisfaction and importance, the target consumers' demand has been studied. And, they are applied to a QFD Matrix, to find out the relationship between the attributes of product quality and the guidelines of clothing design. For this study, apparel product quality is composed of five parameters: practicality, aesthetics, brand image, ease of care and fit. For the parameters of apparel product quality, the result of this study show that product improvements are needed in fit, aesthetics and practicality(in order of importance). The level of satisfaction(how satisfied consumer feels) was marked higher in brand image than that of importance(how important it is). To review demands for the apparel product attributes of formal suits for middle-aged and older women, the priority of these attributes through QFD Matrix that shows the relationship between the attributes and dress elements emphasized by designers has been examined. Material was the most important design element in designing formal suits. The shape of the pants was the second because the harmony between the jacket and the pants is important in formal suits. These were followed by trim and color tone of the jacket.

Objectives : This study is aimed to seek how to promote oral health care by leading the clients with dental fears to change their behaviors in oral hygiene care based on the analysis of the relationships between the dental fears and oral health care behaviors of the clients who visit the Dental Hygiene Education Room. Methods : This study analyzed the 361 dental hygiene records of the subjects with finished treatment and accurate records among a total of 370 clients who had received dental hygiene care at the Dental Hygiene clinic in Y University from March 2007 till June 2009. According to their general features, the study analyzed whether they had any dental fears and why such fears occurred and conducted Chi-square test to compare their oral hygiene care experiences and behaviors with dental fears. Data analysis was made using the SPSS 12.0K for Window, with level of significance set at 0.05. Results : 1. In terms of dental fear or non-fear, the comparison by gender showed that women had a higher level than men, with 76 women(47.2%) answering yes; the comparison by age showed that the age group of 30 years old or older had a higher level than other groups. 2. In terms of dental fear reasons, "the past pain experiences" recorded 34.2%, showing the highest rate. 3. In addition, dental fears had influences on regular dental examination, scaling and dental hygiene education and the subjects without dental fear showed higher levels in terms of tooth-brushing frequency and time. Conclusions : To control "the past pain experiences", future dental treatment should place priority on preventive treatment and get clients to cope with pains through the preliminary education with pains. Besides, to make an effective oral health care of the clients with dental fears, dental hygienists should control the fears of the clients and perform an appropriate oral health care for them using the communication techniques to make friendly and trustworthy impressions.

PCK(pedagogical content knowledge) has been frequently discussed in the field of subject matter education as well as education in general. Considering the fact that PCK characterizes teacher professionalism, and the distinction of mathematics education from neighboring disciplines, PCK is one of the core concepts in the discourse of mathematics education. This study focused on KCS(knowledge of content and students) among the areas of PCK. The purpose of this study to investigate the KCS of pre-service teachers attending a private university located in Seoul. An in-depth interview with 30 pre-service teachers was conducted in a semi-structured manner, using four questions dealing with common student errors, students' understanding of content, and student developmental sequences. The pre-service teachers gave mathematical answers while in others they gave priority to pedagogical considerations. The implication drawn from the interview data is that the teacher training program should fully reflect the complexity of mathematical concepts which appeared in school mathematics over several grade levels and content areas.

Objectives: We describe the development of a smoking and drinking prevention program for adolescents, using intervention mapping. Methods: The study sample consisted of 1,000 high school second-grade students from 6 high schools in Seoul. The PRECEDE model was applied for the needs assessment. We carried out a social diagnosis by assessing the factors such as the quality of life, happiness level, and satisfaction with school life; an epidemiological diagnosis on the perceived health status, stress levels, and priority of health issues; a behavioral diagnosis on the smoking and drinking rate and the intention to smoke and drink; and an educational diagnosis on knowledge, beliefs, attitudes, self-efficacy, outcome expectations, social norms and life skills. Results: The development process included a needs assessment, identifying factors that influence smoking and drinking among adolescents. Intention, knowledge, perceived norms, perceived benefit, perceived cost, perceived susceptibility, self-efficacy, and life skills were identified as determinants. Three performance objectives were formulated to describe what an individual needs to do in order to avoid smoking and drinking. Subsequently, we constructed an intervention matrix by crossing the performance objectives with the selected determinants. Each cell describes the learning objectives of the smoking and drinking prevention program. The program used methods from the transtheoretical model, such as consciousness raising, outcome expectations, self-reevaluation, self-liberation, counterconditioning, environmental reevaluation, and stimulus control. The program deals with the effects of smoking and drinking, self-improvement, decision making, understanding advertisements, communication skills, social relationships, and assertiveness. Conclusions: By using the process of intervention mapping, the program developer was able to ensure a systematical incorporation of empirical and new data and theories to guide the intervention design. Programs targeting other health-related behavior and other methods or strategies can also be developed using this intervention mapping process.

This study describes approaches to fisheries management that restrict access by fishers to an area in some way. When fishery closure is established as a technical conservation measure it is a form of input control as a Korea fisheries management system. There are many compelling reasons why a fisheries manager should seriously consider closed areas and/or time restrictions, either as a complement to other measures or as the primary facet of the Korean fisheries management strategy. Fishery closures have been shown to be effective in many fisheries and are an important tool in the management armoury. In many respects justifications for their use and the process of implementation are likely to be relatively straightforward compared to permanent area closures. From a Korean fisheries management perspective, the benefits that flow from fishery closures are usually less easy to predict than for other management measures. Moreover, even if one accepts that implementation of fisherg clossures will provide higher production levels in adjacent fished areas, the potential benefits may often be in danger of being largely dissipated. If, for example, the fishery remains open access, the increased production is likely to attract new entrants into the fishery, thereby driving it back towards bioeconomic equilibrium. From a Korean wider fisheries conservation perspective, however, fishery closures have important and clearly defensible roles to play and some form of zoning arrangement will often effectively serve conservation values. Given the increasing trend towards the establishment of national networks of fisherg closures, it seems likely that fisheries managers throughout the world will need to ensure that they are familiar with the issues surrounding these approaches. The importance of being explicit about the goals for fishery closures in Korea have been continually emphasised throughout this study. There may, of course, be multiple justifications for the measure, in which case it is important to try and specify them in order of priority.

The lack of research on the suitability of park green spaces as a form of earthquake shelter leads to difficultiesin highlighting the functions of these shelters. In this study, the weight value and priority of 27 indexes derived from previous studies are calculated by the AHP method and then a score table was established via a transformed score method. The final evaluation grade is divided into five levels: very inadequate, inadequate, general, adequate, highly adequate. Finally, indexes that were difficult to judge were explained. Based on this, the suitability evaluation of park green spaces as a form of earthquake shelter can be performed. The evaluation results can reflect the advantages and disadvantages of park green space as a form of earthquake shelter and indicate directionsfor construction in the future.

In this paper, we reviewed the assessment criteria and conservation value used to evaluate vegetation. The Degree of Green Naturality (DGN) and the Grade of Vegetation Conservation (GVC) are both sets of criteria that estimate the degree of human disturbance or natural value of vegetation. The criteria are extensively used in decision-making about the natural environment conservation and environment impact assessment. Sometimes, social issues can rise because the criteria are not clear. This study aims to evaluate the criteria based on the many aspects of the related literatures and suggest reasonable revised criteria. In addition, criteria for representing the relative value of valuable vegetation conservation are suggested. The DGN and GVC are essentially same; both have 11 degrees and 5 grades. While the DGN is subdivided into levels of anthropogenic disturbances, the GVC indicates the priority for conserving valuable vegetation. Therefore, the DGN is very useful for assessing land development projects, etc., while the GVC is needed to delineate the Ecological Assessment Map(EAM). In conclusion, it is desirable that both criteria should be used together appropriately.
