This study is purposed to prepare students in theological universities so that they contribute to their faith community as well as the broader social community in future through developing a practical course model for education of character formation. Facing the challenge of a high-tech revolution being progressed globally in this period, theological seminaries as the Christian-affiliated institute of higher education see the necessity to nurture their learners' competency of holistic personality comprehending cognitive, affective, behavioral, and more spiritual maturity as well as specialty in each subject matter. The holistic character capability of seminarians is closely related not only to their own self-realization, but also social community's well-being. This research had the following content and results. Chapter 1 brought up a subject to educational needs of the holistic character formation in the theological seminaries to meet the rapidly changing times. Chapter 2 considered the importance of character formation in the curriculum of the universities and theological seminaries in the times of high-tech revolution through the literature reviews related to. Chapter 3 clarified the elements of character education to be placed emphasis on theological seminaries and established the way of course planning. Chapter 4, using a course of Christian social education for illustration, described in order the whole process of course planning comprehending the need of planning, description of course concept, establishment and definition of learning outcomes, organization of learning experience(course content), teaching-learning activities, evaluation of learning outcome, and course improvement, which was visualized with the chart of the process of course design. Also, it provided a practical illustration of the conceptual map, an outline of content and an organization of units, and scope-sequence chart. Finally, chapter 5 gave an syllabus example in an integrative and digestive form as the course plan to be distributed to the students, which is the final result produced through the whole process of course planning. This research is intended not to present a overall curriculum planning of the university-level in the theological seminaries, but to develop a course-level curriculum focused on the formation of character. The author hope that this study would be used as a guideline in developing a course model to nurture the capability of the learners' holistic character.

Purpose: To evaluate the recovery time of biochemical changes of body after half-course marathon running. Materials and methods: Thirteen amateur half course marathon runners (12 males and 1 females) were studied. Their average age was 44 years old (range: $38{\sim}54$). Biochemical parameters with blood test including AST, ALT, CK-MB, Treponin, BUN, Cr Na, K were evaluated at finish line, 2nd days, 2nd weeks after running. Results: All the biochemical changes were within normal range throughout recovery time, AST reached its maximum level at finish line and continued until 2nd day after running and returned its pre-running level at 2nd week's test. CK-MB reached its maximum level 2nd day after running and recovered at 2nd week's test. Na, K, BUN and Cr reached to the maximum level at finish line, and recovered to pre-running level at 2nd day's test. Conclusion: In case of half-course marathon, the changes of the kidney enzymes due to dehydration were recovered after 2nd day. And the biochemical indicators of muscle fatigue recovered after 2nd week. It needs at least 2 weeks rest after half-course marathon to recover all the biochemical parameter of the body.

The majority of turfgrass composition of golf courses are zoysiagrass, and mingle with cool-season turfgrasses have been increased. As result of mingling the species, invading problem has been raised. In this study, 50 golf courses nationwide were surveyed of grass composition and invading problem with hetero-species of turfgrasses. Among the courses, 47 golf courses have invading problem with more than one species at least. The invading problem has been issued most of golf course in nationwide. Thirty-seven courses composited with zoysiagrass; at 25 courses showed creeping bentgrass invading and at 33 courses were invaded by kentucky bluegrass. Among 47 kentucky bluegrass composition courses, 43 courses had creeping bentgrass invading problem. Invading problem within the grass species (creeping bentgrass in zoysiagrass, kentucky bluegrass in zoysiagrass, creeping bentgrass in kentucky bluegrass); 14, 12, and 21 courses were detected single species, two species, and three species invading problem, respectively.

The purpose of this study is to investigate middle school student's conceptual change about Force and Motion by the courseware based on constructivism. It is well known to science educators that misconcrptions about physics concepts are hardly changed into scientific ones. So as to change student's misconceptions about force and motion, the courseware was developed through the analysis of students' conceptions. 20 students were tested before and after learning through the courseware. One of the questions was about the direction of force acting on the ball thrown in the air when it is rising, at the top, and falling. The other was about the magnitudes and directions of forces acting on a car when it is accelerating, in uniform velocity, and decelerating. The results are as follows: In case of vertical motion, all students had misconceptions before learning, but after learning 5 students(25%) have changed their ideas into scientific ones. In case of horizontal motion, 9(45%) out of 20 students who had misconceptions about force and motion have changed their ideas into scientific ones.

정부가 올해를‘벤처 활성화 원년’으로 만들겠다며 코스닥 시장 활성화, 자금 지원 등을 주내용으로 한‘벤처기업 활성화 대책’을 발표했지만, 건전한 벤처생태계 조성을 위해서는 보다 먼저 벤처기업과 대기업 간의 불공정 거래 관행 등 근본적인 제도 개선이 선행되어야 한다는 목소리가 드높다. 특히 글로벌 시대에 우리 경제의 신성장동력 창출을 위해서는 더욱 벤처기업과 대기업 간 협력의 필요성이 절실하다. 이익을 독점하는 이기주의는 일시적으로는 득을 보는 것 같으나 장기적으로는 모든 것을 잃는다. 벤처기업과 대기업이 불공정 관행의 사슬을 끊고 협력해서 파이를 더 키워 나누는 상생의 지혜를 발휘하자.

Minkowski sum of two polyedra is an operation to compute the sum of all pairs of points contained in the polyhedra. It has been a very useful tool to solve many geometric problems arising in the areas of robotics, NC machining, solid modeling, and so on. However, very few algorithms have been proposed to compute Minkowski sum of polyhedra, because computing Minkowski sum boundaries is susceptible to roundoff errors. We propose an algorithm to robustly compute the Minkowski sum boundaries by employing the controlled linear perturbation scheme to prevent numerically ambiguous and degenerate cases from occurring. According to our experiments, our algorithm computes the Minkowski sum boundaries with the precision of $10^{-14}$ by perturbing the vertices of the input polyhedra up to $10^{-10}$.

Major Characteristic of the 7th National Curriculum in science is to provide deep and supplementary learning, depending on the level of each learner. In the level-oriented curriculum, coursewares are used to present teaching materials to various levels. In most coursewares, however, they provide their contents at a uniform level and hence it is hard to expect level-oriented learning. This paper presents learner's modeling for developing student's level-oriented dynamic tutoring system for science class , Instructional module of this system made by component unit is able to be reconstructed dynamically. Learning module is constructed using a hybrid model mixed of Overlay and Bug model. Testing module interprets diagnostic errors to be established by given differentiated weight in accordance with item's difficulty and discrimination. Through ITS student modeling, this system presents various problem solving methods reconstructed by learner's level differentiated.

This papers is a study on design and implementation of a web-based courseware for learning Yungwol local community through the internet which is one of the self leading learning methods. Learners can learn Yungwol local community by using the web-based courseware and on the basis of this learning methods, learners can use them according to their wish at anytime and anyplace. The learner-centered teaching model can be offered by sharing, exchanging, and interacting the information each other. To achieve such purpose, two learning grounds are applied. One is the research learning ground which students can study for themselves in the course of searching for the changing cause which can affect to local community and culture. And the other is the experimental ground where is the changing cause searched from research learning ground. Social and physical environment of the lot of community can realized by surfing the network and e-mails producing web-based file through internet. If these web-based research community is more developed and used under the local area network school, self-leading research learning methods will be done regardless of the place and the time.
