The world is changing, Korea is in the middle of the road which is up to the development of culture industry, high profittable industry. The key words of culture industry are the movie ``Avatar`` and I-phone. ``Avatr`` is not simply the conventionally technical film, rather is a phenomenon for hybrid with cutural and technomogical values which is from technologies such as 3D, computer graphics, compositing, and virtual realities. Also, I-phone is not just a receiver, but a surprise as a portal for any contents within small pc, lap top, and game station. The creation of ``Avatar`` and I-phone has the fuction for developing the related culture industries. Their profitabilities are enormous. It has been a long time that The Korea has plunged into the competative market vying for forerunner in the line of digital industry or culture industry. But the question of this paper is whether the proper education is put on this area or not and then the purpose of this essay to pinpoint the blind spot, to anlalyse the cause, and to present the alternative to reality. The author doesn`t have any intentions to harm technological development. The development of technology is unstoppable because it`s a direction to contemporary civilization and profitable pursuit for industry. Even it does not only mean to interrupt the technological development but also to have the conviction that the raising a queston is necessary and positive for how it is proper way to culture creation.

The purpose of this study is to evaluate at which stage of tooth germ would develop into normal calcification and hence to increase the success rate of transplantation. Therefore, tooth germs on the 15th, 17th embryonic day and the 3rd day of birth were separated for allotransplantation into maxilla of adult rat of 11 weeks. Calcification processes were analyzed radiographically and histopathologically at 4 weeks and 8 weeks after allotransplantation. The results are as follows: 1. Allotransplanted tooth germ at 4 weeks and 8 weeks showed delayed calcification compared to that of normal odontogenesis. 2. At 4 weeks, abnormal calcified tissue, such as odontoma and ankylosis of osteodentin with surrounding alveolar bone were observed. 3. At 8 weeks, allotransplanted tooth germs of the 15th and 17th embryonic day showed calcification and osteodentin surrounded by periodontal ligament. 4. At 8 weeks, allotransplanted tooth germs of the 3rd day of birth showed calcification composed of cementum and osteodentin. In this study, we observed small sized and amorphous calcified tissue from allotropic allotransplantation of tooth germs. Since these calcified tissue were underdeveloped and shaped irregularly, for calcification into normal tooth form, further study needs consideration about the reduction of surgical trauma, developmental stage of transplanted tooth germ, blood supply from recipient site, fixation method in transplanted site and period of transplantation. 외상이나 치주 질환,유전적 결함 등에 의하여 치아가 상실되었을 경우,보철 수복이나 임플란트로 치료하고 있다. 그러나 보철 수복이나 임플란트는 자연치가 아닌 인공치를 이용한 치료로서 기능성과 섬미성 등에서 자연치에 비하여 한계 가 있으므로 자연치를 이용한 이식 방법에 관심이 증가하고 있으며 치아 이식의 성공률을 높이기 위한 이식 치아의 발육과 성장에 대한 연구가 진행 중이다. 이 연구는 세 가지 단계의 치아싹을 발치와에 동종 이식하고 치아싹이 발육하여 석회화가 이루어지는지 평가하기 위하여 임선 15일과 17일,출생 후 3일 된 흰쥐의 치아싹을 분리하여 11주 된 흰쥐의 발치와에 이식하고 4주와 8주 후 방사 선학적 그리고 병리조직학적으로 석회화 과정을 관찰하여 다음과 같은 결과를 얻었다. 1. 발치와에 이식된 임신 15일과 17일,출생 후 3일 된 치아싹에서 4주와 8주 후 석회화된 조직이 형성되었다. 2. 임신 15일과 17일,출생 후 3일 된 치아싹을 발치와에 이식하고 4주 후 치아종 같은 비정상적인 석회화 조직과 인접 치조골과 유착된 골양상아질이 관찰되었다. 3. 임신 15일과 17일 된 치아싹을 발치와에 이식하고 8주 후 골양상아질이 보였으며 치주인대로 둘러싸인 것도 관찰되었다. 4. 출생 후 3일 된 치아싹을 발치와에 이식하고 8주 후 골양상아질과 백악질이 형성되었다. 이 연구는 치아싹을 흰쥐의 발치와에 이식한 후 치아싹의 발육을 관찰한 것으로 이식 조직에서 크기가 작고 무정형의 석회화 조직이 형성되었다. 정상적인 치아보다 형태가 불규칙하고 발육이 늦었으므로 이식된 치아싹이 정상적인 치아 형태로 석회화되도록 하기 위해서는 이식 조직의 발육 정도와 이식 조직을 절제할 때 외과적 손상의 감소,치아싹으로의 풍부한 혈류 공급,이삭 기간,이식 조직의 고정을 고려하여 더 많은 연구가 필요할 것으로 생각된다.

Uranium-containing aqueous wastes have been treated by electrosorption on a carbon electrode composed of activated carbon fibers(ACFs) in a continuous flow-through cell. Effective uranium (VI) removal is accomplished when a negative potential in the range of -0.3 to -0.9V (vs. Ag/AgCI) is applied to the carbon electrode. For a feed concentration of 350mg/l, the concentration of U(VI) in the cell effluent is reduced to less than lmg/l. Electrosorption capacity over 552 mg_uranium/g_ACF is reached.

InSb의 결정성장 및 특성

정양준,양순철,이형재 木浦大學校基礎科學硏究所 1989 基礎科學硏究誌 Vol.7 No.-

InSb crystals, both doped and undoped, were grown using the zone-refining technique in vacuum. The unintentionally doped crystals exhibit n-type conduction with the lowest carrier concentration of ??. The pure crystals show intrinsic characteristics even at very low temperatures. Hence very heavily doped n-type crystals were grown in an effort to determine the electron behaviors, not disturbed by the other bands over a wide temperature range. All the InSb crystals prepared in this work were self-seeded along the (111) direction, and the volatilization turned out to be very efficient in reducing the residual impurities during the growing process. The electrical conductivity and Hall coefficient were measured as a function of temperature from 90 to 570K. Theoretical calculations were carried out using a three-band model with the ?? and two hole bands taking into account scattering mehanisms. The results were consistently fitted to the experimental data with the adjustable parameters used in describing the temperature variation of band gap, heavy hole effective mass??, deformation potential??. The final fitting was obtained with the following values, ??, ??, ??. At high temperatures polar optical scattering is dominant for electron scattering and electron-hole scattering becomes very important.

Examined the characteristics of the students who entered Duksung Women's University in 2007. The total number of 1066(out of 1281) undergraduates completed an autobiographical questionnaire which inquires about demographic variables, family environment, satisfaction with the university, expectancies of a campus life, value system, self-concept, and lecture subject. Results show that a majority of the students were graduated from high schools located in Seoul. Both of their parents are alive, in the middle or higher socioeconomic groups and of high educational accomplishment(at the lowest, high school graduates). One of the replicated findings is that students are highly interested in career development. A great proportion of career preparation. The result also indicate that many students have chosen our university solely based on their grades. And many students report that they are satisfied with their choice, which is very encouraging. Other result such as the characteristics unique to each college are also summarized and several suggestions are presented In the discussion section.

In this paper, we proposed pilot channel assisted MMSE-RAKE receiver, which use adaptive filter to provide relatively simple structure and good performance in the DS/CDMA downlink. Especially, utilizing normalized LMS(NLMS) algorithm to resolve the defect of LMS algorithms. And we explained pilot channel assisted method to estimate the multipath fading channel coefficients. With the result of performance analysis, we accepts that the adaptive MMSE-RAKE receiver much relys on the performance of channel estimator.

한국수출기업의 고객지향전략이 해외바이어만족과 관계에 미치는 영향 : 영남지역의 주요 수출국가간 비교를 중심으로

정준식,공재형 한국관세학회 2009 관세학회지 Vol.10 No.1

The main aim of this paper is to investigate the effects of Korea exporting firms' customer orientation strategies on satisfaction and correlation, by comparing Chinese, American and Japanese buyers. For this purpose, this study classified the customer orientation strategies into three types of strategies (i.e. product, transaction, trust orientation) on the basis of previous studies. A email survey was conducted to collect to data for testing eleven hypotheses. Data were analyzed using multi-structural equation modeling by means of AMOS 7.0. The key findings of this study are as follows. Degree of customer orientation (i.e. product & service orientation) of the export firms was found to be related to degree of buyer's satisfaction. It was also identified that the degree of market orientation is a determinant of relationship quality (i.e. trust and commitment).
