Recently, it becomes more important to carry out the feasibility study on government R&D projects since the amount of R&D funds increases. For this purpose, until so far the general framework on the preliminary feasibility study for government driven research projects has been built and modified, and well applied to several domains. However, there is still the limitation in applying the method of preliminary feasibility study to system development research projects. The system development research projects have many different features compared to general research projects, for example, long-period development, lots of stakeholder involvement, multi-disciplinary works, and so on. Considering these characteristics, it is necessary to improve the method for the preliminary feasibility study. In this vein, this study deals with looking into the improvement points of the preliminary feasibility study in terms of the application of the system development projects.

Since 2001, the Pangyo district multipurpose rural water development project has been promoted as a new target project for stable supply of agricultural water and improvement of the living environment of rural areas in Seocheon-gun. Detailed data analysis and logic must be reinforced, focusing on the items reorganized by the reorganization of the preliminary feasibility study. The purpose of this study is to promote the smooth promotion of projects by conducting a policy effect assessment following the reorganization of the preliminary feasibility study system. This study conducted a policy assessment of agricultural infrastructure improvement project for preliminary feasibility study. The policy assessment is divided into three parts: project implementation conditions, policy effects and special assessments. The newly established policy effect is to assess the job effects, living conditions impact, environmental evaluation, and safety evaluation that contribute to the quality of life. Sixteen policy assessment items were selected and evaluated quantitatively and qualitatively. The results of the study are expected to provide basic data for the comprehensive judgment of the preliminary feasibility study of agricultural infrastructure improvement project in the future.

The purpose of this research was to provide basic data to the welfare policy for the aged by studying the relation of health concern, health behavior, and subjective health condition between the aged and the preliminary aged group. Subjects were composed of a total of 259 (116 males, 143 females) living in seoul, aged 50-64(preliminary old people) and over 65(old people), and they were asked to answer the survey Questionnaires The data were analyzed by descriptive statistics, chi-square test, and spearman's correlation coefficient. As a result of the study, the preliminary aged group was significant than the aged group in all three variables. In the relation of health concern and health behavior, there was significance both for the preliminary aged(p〈0.01) and the aged group(p〈0.001). Also, there was significance in the relation of health behavior and subjective health condition of two groups(p〈0.001). However, in the relation of subjective health condition and health concern, there was significance only for the aged group(p〈0.001). For the correlation among three variables, there was significance in the relation between health concern and health behavior and between health behavior and subjective health condition of the preliminary aged group(p〈0.01), but there was significance in the relation between health concern and health behavior and between health behavior and subjective health condition of the aged group(p〈0.01).

In the standards, minimum reinforcement ratios are presented as the least reinforcement ratios that bearing elements should have in a way to include all systems and in general. However, naturally these general minimum ratios might be presented as being lower than the normally required reinforcement ratios by criteria such as system size, bearing system arrangement, section situation and distributions of the elements and earthquake effect. In this case, minimum reinforcement ratios may remain as meaningless restrictions. Then grouping the criterion that might affect reinforcement ratios according to certain parameters and creating minimum reinforcement ratios regarding preliminary design will provide ease and safety during the project designing. Moreover, it will enable fast and simple examinations in the beginning of project control and evaluation process. By means of the data which could be defined as "preliminary design & minimum reinforcement ratios", a more realistic and safe restriction compared to general minimum reinforcement ratios could be presented. As a result of numerous comprehensive studies, reinforcement ratios to include all certain systems might be obtained. Today, thanks to the development level of finite elements programs which can make reinforced concrete modelling, with the studies that are impossible to carry out beforehand, this deficiency in the minimum reinforcement ratios in the standarts may at least be partially made up with the advisory regulation of preliminary design & minimum reinforcement ratios. As the structure of the system to be examined and the diversity of the parameters range from the specific to the general, preliminary design & minimum reinforcement ratios will approximate to general minimum reinforcement ratios in real terms. By focusing on a more specific system structure and diversity of the parameters, preliminary design and even design reinforcement ratios will be approximated. In this preliminary study, a route between these two extremes was attempted to be followed. Today, it is possible to determine suggested practical ratios for project designs through carrying out numerous studies.

This study developed preliminary assessment methodology for priority listing of soil and groundwater contamination sources, considering source characteristics, local environments and risk receptors. Source characteristics were evaluated by scoring relative risk of contamination sources. Local environments were evaluated by scoring annual rainfall, hydraulic conductivity of aquifer, and annual groundwater use. Risk receptors were evaluated by scoring local population, direct distance to surface water, direct distance to drinking-water wells. Scores of each parameter were allocated by analysing distribution of parameter values obtained from government databases. Distributed scores of source characteristics local environments: risk receptors were 12 : 12 : 12. The preliminary assessment scored 0 to 36 for each soil and groundwater sources. Inventory of soil and groundwater sources consisted of 7 categories. This study applied the preliminary assessment methodology to Manan-Gu, Anyang City, Korea. The number of car repair and washing facility was the largest in the contamination source inventory. Petroleum storage facilities showed the highest assessment score. The preliminary assessment methodology also indicated that Anyang-Dong was the priority section among Anyang-Dong, Suksu-Dong, Bakdal-Dong. This study is the first trial for relative ranking soil and groundwater contamination sources by considering source and local characteristics. Therefore, further researches and revision of the preliminary assessment methodology need to be pursued for various applications.

This study was carried out to P University of Education 111 students who participated in science materials study course 1 in spring semester 2011. Students have taken the course pre-service teachers of elementary school classes to target elementary school earth science field, they selected one of the sections to create a class and the students have fulfilled 15-minute classes in respectively from the first week of May 2011 to until end of that course. In this class, colleagues evaluated the classes and we used evaluated scores to determine level of instructional motivation strategy. The obtained results from this study are as follows; First, motivational strategies used by preliminary elementary school teacher were questions, presentation of pictures and photographs, storytelling, presentation of contradictory concepts and phenomena, pilot experiments Second, among preliminary elementary teachers' motivational strategies for teaching in the field of the earth storytelling, presenting contradictory phenomena and concepts, pilot experiment, presentation of contradictory concepts, questions got higher scores in the order. Third, storytelling received the highest scores by the evaluators. So we can consider storytelling as a good strategy for the next class. In particular, storytelling used by animism were more effective. Fourth, preliminary elementary school teachers used life knowledges and dairy experiences as instructional motivation.

The purpose of this study is to understand the effects of ego-resilience, empathic ability of preliminary broadcasters on communication ability and to explore what university should do. The subjects of the study analyzed the relationship between self-resilience, empathic ability and communication ability among 333 preliminary broadcasters in the journal and broadcasting, media related departments of five universities in Busan. As a result of the research analysis, first, the preliminary broadcasters had the highest empathic ability, followed by communication ability and ego-resilience. Second, ego resilience according to the general characteristics of preliminary broadcasters was significantly different according to gender, major satisfaction, and club activities. There were significant differences according to satisfaction and club activities. Third, the correlation between ego resilience, empathic ability, and communication ability of preliminary broadcasters has a significant static correlation, and the correlation between empathic ability and communication ability is the highest. Fourth, the factors influencing communication ability were empathic ability, ego resilience, and gender. It will be meaningful as a study that the factors influencing communication ability related to preliminary broadcasters are empathic and ego resilience. Therefore, it is necessary to prepare a plan such as opening a curriculum to improve the communication ability of preliminary broadcasters.

The paper describes the preliminary ship design method using deterministic approach and probabilistic approach. In deterministic approach, there are computational aspects to applying not only the integration concurrently of principal dimension decisions and hull form variations but also hydrostatic coefficients that applied to optimization iterative process. Therefore, this paper developed that actual design concept at the preliminary ship design more than sequential design which separated in principal dimension decisions and hull form variations. Furthermore, a probabilistic approach at the preliminary ship design is applied to efficiently solve design information uncertainty that compared to deterministic approach.

The objective of this study is to present and to analyze preliminary orientation design factors in the design stage of sustainable architecture in the viewpoint of technocentrism. Typically people interpret solar energy system architecture as simply being part of a mechanical system. Yet, even before considering energy-consuming physical systems in buildings, it is very important to consider the outer parameters of sustainable design factors and the design process itself for the effective and suitable energy-saving design methodology. By analyzing the evolving phases and history of technocentrism and solar energy systems in sustainable architecture through examples and case studies, this paper focuses on and proposes preliminary orientation design factors that should be considered when starting the architectural design process in the viewpoint of technocentrism.
