As Japanese economy has been well developed, the manpower problem of farmland has also become one of the largest and the most crucial issues in the overall agricultural policy of the Japanese Government. Particularly, the energetic younger generation and a core of agricultural labor force, has drastically decreased, while the weak older generation has increased. The severity of manpower shortage in agricultural sector led to create a farmer training programs which had been vigorously begun by the Yamagata Prefecture, and a center for promoting local autonomy. The major purpose of education for enhancement of status of future farmers as well as the welfare of core farmhousehold is to provide them with technical of vocational education to give training to those who want to become agricultural technicians, rural leaders of practical farmers Educational program for future and young farmers put emphasis on practical trainings which are directly applied to proper farm management. As a supporting policy for promoting future farmers' activities, Prefecture-level supports were strengthened to develop technical capability, managerial and supervisory ability, and the ability to lead organized activity so that the farm youth may operate modern farms with higher efficiency and greater specialization. Political consideration was also made to develop a rich sense of farm management as well as the adaptability necessary to introduce technical and managerial innovations. Methological measurements on how the Korean government has to do for solving the problem of agricultural manpower facing in farmland in Korea were noted.

This study investigated the effects of the application of a variety of ICTs cause the effects on self-directed learning capability, creativity and problem-solving ability. In order to achieve the above aim, Web-Based Instructions(WBI) and instructions using CD-ROM Titles for the unit of 'the solar system and the galaxy' were applicated and analyzed which belongs to the area of 'the earth' in the subject 'science' for high school students. Instructions using WBI materials and CD-ROM titles were found to be effective on 'self-conception', 'creativity', 'future inclination', 'self-assessment ability', 'openness' and' initiative' improvement all of which belong to self-directed learning characteristics. They did not, however, show meaningful effect on improving 'learning eagemess' and 'responsibility' improvement. On looking into self-directed learning characteristics according to prerequisite learning levels, both groups and these for instruction using CD-ROM learning materials were found to have no effect on interaction. With respect to problem-solving ability improvement which is characteristic of the instruction using ICTs, WBI proved more fruitful than instruction using CD-ROM titles on improving scholastic achievement level. WBI was effective on 'fluency', 'originality' and 'resistance to premature closure'. It on the other hand, was of no use on 'abstraction of titles' and 'elaborateness' These results came from the following characteristics: WBI came into effect on 'fluency' and 'originality' in the areas of variety and vitality, which are characteristic of WBI. In the area of resistance to premature closure WBI was effective on organizing learning contents owing to the animation of picture materials which are variously presented in the web site. As a result of WBI questionnaire about WBI, an excellent effect on the structure of display, quantity of information, indication and instruction, supplementary study and further study were discussed.

Creativity is an essential ability for a successful design task, mainly because design is an activity creating something new. As the sphere of design has expanded and become complex, the design task goes beyond an individual designer's capability. Therefore, it is necessary to organize a design team consisting of various team members with diverse expertises. The aim of this study is to find out the impact of fundamental attributes of members on the group creativity in order to establish a guideline for building a creative design team. Heterogeneous teams and homeogenous teams were created according to three main factors of group creativity namely, personality, field and experience. The group creativity of each team were evaluated through protocol analysis of design activities as well as the comparison of problem solving processes and outputs. It was identified that the impact of design teams on the group creativity was distinctively different in four phases of the design process (preparation, divergence, convergence, and execution) regarding creativity properties such as fluency, elaboration, originality, usefulness. Based on these findings, a schematic model for building a design team in order to enhance the group creativity by composing the most appropriate team members for each phases of the design process was developed.

This study aimed to distinguish between predisposing factors influencing the entrepreneurial intentions of university and college students who completed an entrepreneurship education course and to empirically determine the relationship between entrepreneurial intention and entrepreneurial behavior. Since company foundation involves uncertainty, potential entrepreneurs are known to fear creating a new company. Entrepreneurship has been confirmed in advanced studies to not only reduce this fear but also positively influence one's entrepreneurial intention. This study presents a research model that connects entrepreneurship, entrepreneurial intention, and entrepreneurial behavior and verifies it via empirical analysis. It was confirmed as a result that entrepreneurial intention is positively influenced by actively engaging with changes of a certain product or service, problem-solving capability, resolving unexpected setbacks during company foundation, and expertise in the business field where the founded company belongs to. It was also confirmed that entrepreneurial intention has a positive influence on entrepreneurial behavior. In the conclusion of this study, importance and necessity of entrepreneurship education are discussed in order to essentially improve entrepreneurial intention and company foundation via entrepreneurship education.

The need for radio spectrum is recently considered as a huge hurdle towards the rapid development of wireless networks. Large parts of the spectrum are allocated to licensed radio services in proprietary way. However, enormous success of the wireless services and technologies in the unlicensed bands has brought new ideas and innovations. In recent years cognitive radio has gained much attention for solving the spectrum scarcity problem. It changes the way spectrum is regulated so that more efficient spectrum utilization is possible. Multi-hop relay technology on the other hand has intensively been studied in the area of ad hoc and peer-to-peer networks. But in cellular network, only recently the integration of multi-hop capability is considered to enhance the performance significantly. Multi-hop relaying can extend the coverage of the cell to provide high data rate service to a greater distance and in the shadowed regions. Very few papers still exist that combine these methods to maximize the spectrum utilization. Thus we propose a network architecture combining these two technologies in a way to maximize the system throughput. We present the throughput capacity equations for the proposed system model considering various system parameters like utilization factor by the primary users and primary users' transmission radius and through extensive numerical simulations we analyze the significance of work.

The finite element method (FEM), a powerful numerical modeling tool for solving various engineering problems, is frequently applied to three-dimensional (3-D) modeling thanks to its capability of discretizing and simulating the shape of model with finite number of elements. Considering the accuracy of the solution and computing time in modeling of engineering problems, it is preferable to construct physical continuity and simplify mesh system. Although there exist systematic mesh generation systems for arbitrary shaped model, it is hard to model a simple cylinder in terms of 3-D coordinate system especially in the vicinity of the central axis. In this study I adopt cylindrical coordinate system for modeling the 3-D model space and define the origin of the coordinates with mathematically clear coordinate transformation. Since we can simulate the whole space with hexahedral elements, the cylindrical coordinate system is effective in handling the 3-D model structure. The 3-D do resistivity modeling scheme developed in this study provides basie principle for borehole-to-surface resistivity survey, which can be a useful tool for the application to environmental problem.

This research is to provide a useful reference for the future revision of textbook by comparative analysis with the textbook in the 4th grade of elementary school in Japan. The results from this research is same as follows: First, Korean curriculum is emphasizing the reasonable problem-solving ability developed on the base of the mathematical knowledge and skill. Meantime, Japanese puts much value on the is focusing on discretion and the capability in life so that they emphasize each person's learning and raising the power of self-learning and thinking. The ratio on mathematics in both company are high, but Japanese ensures much more hours than Korean. Second, the chapter of Korean textbook is composed of 8 units and the title of the chapter is shown as key word, then the next objects are describes as 'Shall we do$\sim$' type. Hence, the chapter composition of Japanese textbook is different among the chapter and the title of the chapter is described as 'Let's do$\sim$'. Moreover, Korean textbook is arranged focusing on present study, however Japanese is composed with each independent segments in the present study subject to the study contents. Third, Japanese makes students understand the decimal as the extension of the decimal system with measuring unit($\ell$, km, kg) then, learn the operation by algorithm. In Korea, students learn fraction earlier than decimal, but, in Japan students learn decimal earlier than fraction. For the diagram, in Korea, making angle with vertex and side comes after the concept of angle, vertex and side is explained. Hence, in Japan, they show side and vertex to present angle.

This study is on improving the general engineering education for enhancing the quality of engineers at a local engineering school in which the students are not highly qualified for engineering education. Based on the analysis on the current engineering education by asking questions to professors, students and alumni of Hongik College of Science and Engineering, we have set the basic educational philosophy as educating practical engineers and have decided the goals of basic engineering education as changing to student oriented education, enhancing the field adaptation capability, improving the problem solving ability and introducing engineering design courses. For achieving the foregoing goals, we have changed several basic engineering courses. Mathematics, science courses, computer related courses, English, communication skill related courses are strengthened, but general college education courses are reduced. We also have encouraged students to participate the classes actively and study efficiently, think logically and creatively. For the operational details, we have tried to impose less courses to freshmen and sophomores, to impose the prerequisite courses, to activate summer and winter schools. Finally, we have tried to find the ways to support continuous improvement on the basic engineering education.
