The objective of this study was to design a fashion storytelling method, which is a strategic instrument for constructing a fashion show with artistry and popularity, based on the principle and structure of storytelling. In order to understand the concept and principle of storytelling composed of story and telling and to introduce storytelling into fashion shows, we associated fashion design with the substance of a story, a show with the form of telling, and a fashion show with storytelling. Based on these associations, we analyzed the relationship between fashion show and storytelling and developed basic elements and structure necessary to design a fashion storytelling method. Through this study, we designed a fashion storytelling method with five steps, which are story planning, story development, fashion show structure design, fashion show production, and fashion show execution. These steps were again classified into contents setting step, structure design step, and expression step. The contents setting step included story planning and development for creating stories, and the structure design step means the design of fashion show structure that adds telling to the stories. Lastly, the expression step included fashion show production and execution that forms a storytelling by combining the stories and the telling.

As the population of the aged and the disabled increases, the needs for universal design is also growing. Universal design is to design for diverse users including all ages from children to the elderly, the disabled and non-disabled, the pregnant, the tourist, and etc. This study is intended to develop the design evaluation tool and guidelines of universal design for applying to space design. In order to achieve this, four basic spaces in human living such as residential space, educational space, working space, and cultural space were selected. Then, the elements of universal design were chosen for each space. The numbers of areas in each space were 12 for residential spae, 5 for educational space, 6 for working space, and 6 for cultural space. Also, 60 elements of universal design for residential space, 53 for educational space, 36 for working space, and 46 for cultural space were selected. The field observation with photos and user evaluation survey were carried out for each space by using these elements. Finally, the elements and guidelines of universal design applied for spatial design were suggested. This consisted of 8 areas and 67 elements. This would be useful for designing space for all people.

In recent years, the development of application programs for distribution system analysis and control has been essential part for distribution management system (DMS). In this paper, we propose the common database for application programs of distribution management system. The proposed database model has several characteristics as followings. First, the proposed database model is designed for the common use of almost the whole distribution application software. The static equipment model and dynamic type tables are mixed and the parallel table structure is applied. Second, the linked list structure of database are used for the fast processing of applications. The database model includes the hierarchy and non-hierarchy distribution system structure. Third, the reduction method of distribution database is applied. For this, we present the network reduction rules. The basic concept of reduction rules are the electrical unification of successive line section which has not lateral branches and the removal of simple lateral branches which has no devices and other laterals. Proposed database model is tested for the Jeju system of Korea Electric Power Corporation (KEPCO). Through the test, we verified that the proposed database structure can be effectively used to accomplish the distribution system operation.

Most of developed countries, the consumption of fossil fuels has been serious problems that cause serious environment pollution like acid rain, global warming. Also, we have faced that limitation fossil fuels will be exhausted. Currently, small hydropower attracts attention because of its small, clean, renewable, and abundant energy resources to develop. By using a small hydropower generator of which main concept is based on using the different water pressure levels in pipe lines, energy which was initially wasted by use of a reducing valve at the end of the pipeline, is collected by turbine in the hydropower generator. A propeller shaped hydroturbine has been used in order to use this renewable pressure energy. In this study, in order to acquire basic design data of tubular type hydraulic turbine, output power, head, efficiency characteristics due to the flow coefficient are examined in detail. Tubular-turbine among small hydraulic power generation can be used at low-head. The purpose of this study is to research turbine's efficiency due to runner vane angle using CFD analysis.

Even though geometry is an important part basic to mathematics, studies on the program designs and teaching strategies of geometry are insufficient. The aims of this study are to propose the model of program design for autonomous learners taking their characteristics of the mathematically gifted into consideration. The core of teaching materials are analytic geometry and projective geometry. And the new teaching strategy will introduce three steps ; a draft strategies step(problem presentation, problem solving), a supportive strategies step(abstraction of a mathematical concept, mathematical induction, and extension), a transference strategies step to teaching strategy suitable for mathematically gifted. As a result, this study will suggest the effective methods of geometry teaching for the mathematically gifted.

The development of large-scale environmental friendly livestock complex in the reclaimed tideland is one of different alternatives to increase the competitiveness of internal livestock industry against an international opening markets as DDA and FTA in agricultural field. Recently, it is possible to introduce an environmental friendly livestock complex in the reclaimed tideland by an amendment of the acts for agricultural land. However more studies that are on the basis of nitrogen and phosphorus mass balance need to preserve the agricultural environments as the quality of agricultural water and soil in rural area. In this study, the reference for feasibility study is Whaong reclaimed tideland which located at Whaseong city, Gyeonggi Province, and a basic concept of environmental friendly livestock complex is the production of forage crops with the supply of liquid fertilizer and the production of bioenergy such as biogas by the recycling of pig slurry as a resource. The mass balance of nitrogen based on between forage crops such as maize, barley and liquid fertilizer supplied at the reclaimed tideland, and also it was estimated an economical efficiency as anaerobic digestion plant for treating pig slurry of $100m^3/day$ introduce in an environmental friendly livestock complex.

The pilot aptitude test so far has been conducted with a dichotomous concept of cognitive factor and non-cognitive factor, so it was not easy to explain concrete factors about pilot aptitude. Therefore, an integrated approach is needed to construct pilot aptitude test including all factors that can predict pilot aptitude. In previous study, we developed questionnaire items for the Pilot Aptitude Personality Test(PAPT) which can predict the flight training achievement through personality and personal characteristics. And those items were categorized as personality, cognition, and motivation factors. The flight training grades were correlated with all the test factors of the items, and the cognitive factors were high. As a result of the regression analysis, the total score of the three factors together accounted for 16% of the flight training grades. The results of the ANOVA showed that the cognition factors and motivation factors had significant effects on the completion of the flight training. The factors of PAPT predicted not only the completion of the flight training but also the flight performance. This is because the existing paper-pencil pilot aptitude test can only discriminate the flight training completion status. This is also a result of the fact that the introductory flight training consists of various factors including not only basic cognition but also personality and motivation.

In this research, a way to design a more convenient road for walking by creating more pedestrian space for streets located in busy areas due to many people crowded together was looked into. A symbol or characteristic was given to the street representing the image or regional culture of the area, and effort was given to create convenient yet characteristic street landscape by turning an environmentally sound, open area into pedestrian space. The basic concept of pedestrian space design was taken as the correlations between physical and psychological factors that appear on the environmental aspect of landscape. Areas for which it was difficult to come up with, a method to create a unique open space for pedestrians was looked into by analyzing with other known cases where the pedestrian area landscape was compared with that of the area in question.
