The purpose of this study is to explore the philosophical position of various scientific theories based on the scientific worldviews for science education. In addition, it aims to expand science education, which has usually dealt with epistemology and methodology, to ontology, that is, to the problem of metaphysics. It can be said that there exists a physical realism, traditionally defined as a strong determinism of the metaphysical belief. That is fixed and unchanging objective scientific knowledge independent of our minds, which was established by Newton, Einstein and Schridinger. What can be seen in the natural laws of dynamics can be called 'mathematicization'. Einstein also shook the traditional views to some extent through the theory of relativity, but his theory was still close to traditional thinking. On the contrary, to escape from this rigid determinism, we need anthropomorphic concepts such as 'possibility' and 'chance'. It is a characteristic of the modern scientific worldviews that leads the change of scientific theory from a classically strong deterministic thought to a weak deterministic accidental accident, probability theory, and a naturalistic point of view. This can be said to correspond to Darwin's theory of evolution and quantum mechanics. We can have three types of epistemological worlds that justify this ontological worldviews. These are rationalism, empiricism and naturalism. In many cases, science education does not tell us what kind of metaphysical beliefs the scientific theories we deal with in the field of education are based on. Also, science education focuses only on the understanding of scientific knowledge. However, it can be said that true knowledge can bring understanding only when it is connected to the knowledge of learned knowledge and the learner's own metaphysical belief in the world. Therefore, in the future, science education needs to connect various scientific theories based on scientific worldviews and philosophical position and present them to students.

본 논문은 신재생에너지 발전전원 중 단속적 특성이 강한 풍력발전 전원의 용량가치 평가방법에 관한 것이다. 풍력발전의 설비가치는 확률론적 접근방법과 용량률에 의한 결정론적 접근방법을 사용할 수 있으며 미국의 주요 산정방법을 살펴보고 국내 적용가능한 대안을 수립한다. 풍력발전의 설비가치를 실효성있게 산정하기 위해서는 관련자료의 확보가 우선되어야 하나 국내의 자료확보체계 및 그 기간이 짧은 관계로 용량률에 근거한 단순기법이 실효성이 있을 것으로 판단된다.

This research has a purpose to verify whether the Internet diffusion through the Official Development Assistance (ODA) can bring about democratic changes in authoritarian political system of developing countries. This research has found out that IT ODA has 'positive(+)' effect on the Internet diffusion in recipient countries. It seems to support the expectation of donor countries that they can lead the political democratization by constructing infrastructure and promoting the use of the Internet. However, as the impact of IT ODA on the Internet diffusion is not considerable as well as the Internet diffusion has no strong influence on the development of democracy in developing countries, and also each of these aspects of countries looks different, it is hard to see that the democratization hypothesis based on the optimistic technological determinism is reasonable. Therefore, this paper argues that IT ODA must be based on not blind optimism that IT transfer will lead to the political democratization in developing countries, but the social structuralism which is based on distinctiveness and uniqueness of countries. and suggests that the discuss of the effect of IT ODA proceed with the constructive way.

C-axis-oriented ZnO thin films were successfully deposited on p-Si (100) in an RF magnetron sputtering system. Deposition conditions such as deposition power, working pressure, and oxygen gas ratio were varied. Crystalline structures of the deposited ZnO films were investigated by a scanning electron microscope (SEM) technique. Results show that the deposition parameters can have a strong impact on the preferred orientations and grain sizes of the deposited ZnO films.

고주파 마그네트론 스퍼터법을 이용한 YIG(yttrium iron garnet)박막 제조시 기판유형, 기판온도, 스퍼터전력, 스퍼터가스 등의 증착변수와 증착후 열처리 조건이 YIG 박막의 결정성, 화학조성, 미세구조 그리고 자기적 특성에 미치는 영향에 대하여 고찰하였다. 75$0^{\circ}C$ 이상의 온도에서 수행한 증착후 열처리에 의하여 비정질 박막이 결정화되었으며, 특히 GGG(gadolinium gallium garnet)기판 위에 제조된 박막은 강한 (111)우선배향성을 나타냈다. 박막조성은 스퍼터가스 내의 산소분율에 민감하게 영향을 받았으며, 산소분율이 20%인 스퍼터가스를 사용하여 제조된 박막은 Y2.88Fe3.84O12의 조성을 나타내었다. 증착후 열처리 온도가 90$0^{\circ}C$로부터 110$0^{\circ}C$로 증가함에 따라, GGG 기판위의 박막의 표면거칠기는 2.5nm에서 40nm로 증가하였으며, 보자력과 강자성 공명 선폭은 감소하였다.

본 연구는 가족의 구매의사결정에 대한 실증조사로서 성별역할관념론 및 자원이론과 가족구성원의 지각된 영향 간의 관계를 규명하였다. 영향을 주는 구성원은 남편과 아내와 자녀로 한정했으며, 영향을 지각하는 가족구성원은 남편과 아내로 제한하였다. 성별역할관념변수는 Scanzoni Sex-Role Scale(SSRS)로 측정하였으며, 자원변수는 남편과 아내 각자의 수입과 교육수준으로 측정하였다. SSRS 는 요인분석을 사용하여 차원(요인)을 파악한 후 자원변수와 함께 지각된 영향 간의 관계를 규명하기 위하여 다변량 회귀분석을 사용하였다. 요인분석 결과는 Scanzoni(1975)의 분석 결과와 요인구조 면에서 차이가 있었다. SSRS 는 아내의 척도 2 개 차원과 남편의 척도 3 개 차원으로 구성되어 있다. 그러나 본 연구에서 남편의 척도는 1 개의 차원으로 나타났다. 조사대상이 된 제품은 TV, 냉장고, 세탁기, 침대, 장롱, 식탁, 자동차, 남성정장, 여성정장, 여행지로 모두 10 개 였다. 성별역할관념변수의 영향을 분석한 결과는 "제품 특이적"이거나, 영향을 지각하는 "지각주체 특이적"이거나, 성별역할관념의 "차원 특이적" 현상을 보였다. 또한 우리나라의 남편들은 성별역할관념변수에 상관없이 자기의 영향을 더욱더 크게 지각하는 반면, 아내의 영향을 더욱더 적게 지각하는 경향이 있었다. 아내들도 남편보다는 자기의 영향을 더욱더 크게 지각하는 경향이 있으나 남편만큼 강한 것은 아니었다. 이 결과를 분석하면 남편들은 남성우월의 전통을 유지하려는 경향이 높은 반면 아내들은 이런 전통에 변화를 기대하는 진보적 성향을 띠고 있는 것으로 해석된다. 본 연구의 결과 자원이론은 지지를 받지 못하는 것으로 나타났다. 다시 말해 자원이론은 부부사이에서 기대했던 영향과 반대 방향으로 나타났을 뿐만 아니라 부모와 자식 간에도 기대했던 것과 반대 방향으로 나타났다.

Les positions qu'essait d'expliquer les $probl{\grave{e}}mes$ divers ${\grave{a}}$ propos de la $sexualit{\acute{e}}$, faisaient ressortir les points biologiques des actions $d^{\prime}{\hat{e}}tre$ humain par ${\acute{e}}volutionnisme$ plutot qu'explique les $probl{\grave{e}}mes$ de la nature humaine, $d{\acute{e}}sirs$ sexuelles, par les $sci{\acute{e}}t{\grave{e}}s$, les cultures et les'institutions. En face des questions des $possibilit{\acute{e}}s$ d'explications biologiques sur toutes les actions sexuelles, ils sont $plac{\acute{e}}s$ en crise. Le fait que $l^{\prime}{\hat{e}}tre$ humain est un'etre historique, n'implique pas ce qu'il est evolutionnaire. Pour cette raison, c'est difficile qu'on accepte le determisme biologique, $l^{\prime}{\acute{e}}volutionnisme$, sans conditions. En opposition avec cettes $id{\acute{e}}es$, Michel Foucault voudrait insister sur le fait de penser au sexe comme les $r{\acute{e}}sultats$ des productions sociologiques, politiques. Selon Foucault, la $sexualit{\acute{e}}$ n'est pas $donn{\acute{e}}$ de la nature que le pouvoir essaierait de mater, ou un domaine obscure que le savoir tendrait de $d{\acute{e}}voiler$, mais une sorte de dispositif historique. Donc, dans cet article, j'essaie d'examiner les processus, les differences, et les $probl{\grave{e}}mes$ entre les deux positions, puis je considere les limites philosophiques, des deux argumentations, et ses implications philosophique. Cela permet d'approcher ${\grave{a}}$ l'horizon divers du discours sexuelles de la $compr{\acute{e}}hension$.

It has become important to have some proper guidelines of how to provide public transport information services in response to the rapid IT developments and the wide spread of public information services. The current study takes a contextual approach to the analysis of public transportation information use under a dynamic decision situation, complementing the conventional cross-sectional approaches. Using the CHAID of decision tree induction based on decision table formalism applied to the survey data of activity travel and information use, the study found that the information type and medium choices are strongly affected by the decision contexts in addition to the individuals' socio-demographic characteristics. The results suggest an important implication to the market segmentation of information services for public transportation.

C-axis oriented zinc oxide thin films were deposited on Si(100) substrate by rf magnetron sputtering. The effects of deposition parameters on the crystallinity and electrical properties of ZnO films were investigated. As-deposited ZnO films showed the strong c-axis growth andexcellent crystallinity under the deposition conditions as follows ; substrate temperaturec : $200^{\circ}C$, rf power : 150W, gas ratio : $O_2/Ar=50/50$, chamber pressure : 10mTorr. The resistivity of ZnO films was significantly affected by deposition parameters. With increasing percentage of oxygen, and decreasing substrate temperature, the resistivity of ZnO films increased.

Zinc Oxide(ZnO) thin films on Si (100) substrate were deposited by RF magnetron sputter with changing sputtering conditions such as argon/oxygen gas ratios, RF power, and substrate temperature, chamber pressure and target-substrate distance. To analyze a crystallographic properties of the films, ${\Theta}/2{\Theta}$ mode X-ray diffraction, SEM analyses. C-axis preferred orientation highly depended on RF power.
