The goal of current study is to carry out comparative analysis on the relationship between nature perspectives and their corresponding utilities by taking integrated approach combining economic values with environmental ones. The results are as follows. First, empirical evidence shows that the structures of happiness function differ according to nature perspectives. The anthropocentric-nature perspective is centered on economic value. Whilst, environment and social trust play an statistically insignificant role in deciding happiness levels. Secondly, the eco-centric perspective possesses a multi-facted structure of happiness function composing of income, environment, and social trust. In this vein, it is no reasonable behavior, from happiness maximization view, to focus on economic value vis-a-vis use value.

In this study, the views and the meaning of nature between the Western world and East Asia were compared through literature analysis. In the West, it is recognized that nature and human beings are separate. Nature is understood as regular and rational. They, therefore, take the view of particle and mechanical theory. In East Asia, it is thought that nature and humans interact with each other, and take an attitude of compromise and tolerance. Since nature is recognized as an ever-changing being, they, therefore, take the position of wave theory. Scientific knowledge and concepts are accepted depending on the personal view of nature. In Korea, science education follows the view of modern western science without considering the personal pattern of cognition, though students can have various views of nature. The attitude is needed regarding the various viewpoints as rich resources in science and science education.

We investigated people's patterns of reasoning regarding the Korean traditional interpretation of Planet Occultation by the Moon. A questionnaire survey was administered to the sample which consisted of 632 participants: middle school students(n=164), high school students(n=157), university students(n=172), and the public(n=139). It was revealed that 15.7% of the participants agreed, 38.1% disagreed, and 46.2% were neutral to the traditional interpretation. A comparatively large portion of the university students made a scientifically correct judgement by disagreeing with the traditional interpretation. On the other hand, a relatively small proportion of the middle school students disagreed. Participants' views of nature and views of science were the major reasons for making their judgements. Most participants were fixed with similar views to the Korean traditional view of nature. Most of the participants valued using more extensive evidence and experimental proofs in science. High school and university students considered their metaphysical beliefs, such as view of nature and view of science, more important than other groups did. In contrast to this, middle school students and the public depended more strongly on their personal experiences. Participants' social experiences and their scientific knowledge were also important reasons for making their judgement. However the differences in their scientific knowledge seemed to exert different influences on their reasoning. The results of this study show differences in how an individual thinks as well as differences between communities. Thus, science education and research considering multicultural settings are needed. In addition, science educators and researchers should pay attention to pupils' metaphysical beliefs such as their views of nature and views of science.

Purpoose: For decades dental implants have been used widely in the field of prosthetic dentistry. However there is confusion when establishing treatment plans in cases where some teeth are remained but an insufficient number of implants can be used due to limited anatomical status and ecomomical problems. Many clinicians have tried to connect natural teeth and implants, and it still has controversy. But, there have been few studies on mechanical analysis of connecting natural teeth and implants with konus telescopic removable partial dentures. The purpose of this study was to analyze the stress distribution of prosthesis, abutment and alveolar bone when teeth and implants were connected with the konus telescopic denture, by means of 3-dimensional finite element analysis. Material and methods: The assumption of this study was that there were 2 mandibular canine (11 mm in length, 4 mm in diameter) and 2 implants(10 mm in length, 4 mm in diameter) which are located in the second premolar region. The mandible, teeth, implants, abutments, and connectors are modeled, and analyzed with the commercial software, ANSYS Version 8.1(Swanson, Inc., USA). The control group used implants instead of natural teeth. 21038 elements, 23544 nodes were used in experimental group and 107595 elements, 21963 nodes were used in control group, Stress distribution was evaluated under 150 N vertical load on 3 experimental conditions - between teeth and implants (Load case 1), posterior to implants (Load case 2), between natural teeth (Load case 3). Results: 1. In all load cases, higher von mises stress value was observed in the experimental group. 2. Maximum von miss stress observed in all load cases and all locations were as follows ; a. 929.44 Mpa in the experimental group, 640.044 Mpa in the control group in outer crown and connector - The experimental group showed 1.45 times high value compared with the control group. b. 145,051 Mpa in the experimental group, 142.338 Mpa in the control group in abutment - The experimental group showed 1.02times high value compared with the control group. c. 32.489 Mpa in the experimental group, 25.765 Mpa in the control group in alveolar bone - The experimental group showed 1.26times higher value compared with the control group. 3. All maximum von mises stress was observed in load case 2, and maxim von mises stress in alveolar bone was 32.489 Mpa at which implant failure cannot occur. 4. If maximum von mises stress is compared between two groups, the value of the experimental group is 1.02 times higher than the control group in abutment, 1.26 times higher than the control group in alveolar bone. Conclusion: If natural teeth and implants are connected with the konus telescopic denture, maximum stress will be similar in abutment, 1.26 times higher in alveolar bone than the control group. With this result, there may be possible to make to avoid konus telescopic dentures where natural teeth and implants exist together.

우리의 문화적 특성은 어떤 것인가 관심과 노력 그리고 연구는 오늘날까지 문화인류학, 사회학, 예술 등 다양한 분야에서 지속되고 있다. 디자인 분야에서도 마찬가지인데 특히 광고계에서 국적있는 광고, 한국적 과고라는 명제로 많은 크리에이터들이 그 실체를 찾으려 고민하고 있으며 각종 광고사보에 단편적인 글들이 게재되고 이다. 어떤 대상의 특질을 살피기 위해서는 시각(視角)의 중요성이 대두되는데 한 나라의 문화유형도 마찬가지임은 말할 것도 없다. 1994년부터 문화인류학적으로 연구된 유수한 저시로 오늘날까지 일본론의 고전이라할 루드베네딕드의 <국화와 칼>은 서양인의 눈에서 일본을 보고 서양과 비교하여 일본인을 서정적이며 자연을 사랑하는 우수한 민족으로 그리고 있다. 일본인이 쓴 일본에 대해<日本人\ulcorner表現心理>에서 \ulcorner\ulcorner\ulcorner는 "일본만큼 자연을 사랑하는 민족은 없다. 부자연 싫어한다. 자연관, 자주관은 담백, 표백, 무상"이라 쓰고 있다. 우리는 한국의 그림이나 도자기 등의 조형성을 이야기할 때 여백의 미라는 말을 종종한다. 그런데 차후 본 연구에서 다루어지겠으나 다나까이꼬의 그름에 대하여 가메꾸라유사구는 그것을 여백의 미라 하면서 일본적임을 강조하고 있다. 한국과 일본은 문화형성 배경에 있어 유사한 문화적 특질을 공유하고 있는 것은 사실이나 학문적 중립성에서 두 조형성을 비교해볼 때 일본인이 말하는 여백과 한국의 여백, 그리고 일본의 자연적인 것과 우리의 그것은 전연 상이한 것이다. 이렇게 일본과 지정학적으로 가까이 위치하고 있으며 고대사에서는 한 문화를 이루었고 근대사에서는 30여 년간 구체적인 문화를 경험한 한국인의 시각에서 바라본다는 것은 훨씬 근접한 이해에 도움을 줄 수 있을것이라 생각된다. 한국인의 시각에서 일본을 보면 베네딕드나 방하 수의 인식이 얼마나 편견인가 하는 것을 실감하게 된다. 본 연구는 일본의 문화속성 가운데 내재되어 있는 구체적인 조형성을 발굴함으로써 한구그이 조형성으로 필자가 유추하고 있는 '부드러움'이라는 개념을 상대적으로 명확히하고자 하는 데 그 의의가 있다.

The progress made by scientific development achieved the goal for making human environment convenient and functional. However, it also caused excessive expanse of artificial environment, which in turn produced undesirable segregation between human and nature. Recently we frequently see ecological space designs which try to be synchronized with nature not only in technological terms, but also in psychological terms. This paper examines various viewpoints for ecological space design. First, it studies philosophical backgrounds of ecological space design through comparative analysis between eastern and western ideas of nature. Then it classifies the types of viewpoints for ecological space design with supporting explanations from scientific proofs. Finally, it provides case analyses for each of these views. This research aims at proving the value of ecological space design so that it can guide future direction of space design toward reestablishing the organic relationship between human and nature.

The ultrasonic inspection system for the expansion/transition area of steam generator tube was successfully developed. Variety of artificial flaw and real track specimen was tested using the UT system to verify the performance of the system. All artificial flaws of which through-wall depth larger than 10% was clearly detected by UT system. Measurement results of through-wall depth of flaws larger than 20% had good linearity and reproducibility with 3.27 of standard deviation. Results of real crack specimen test suggested that the detection limit of real crack strongly depends on the track morphology. A potential for measurement of PRL(percentage of remaining ligament) was recognized by the real crack specimen test.
