채규연 ( Kyu Yeon Chae ),조영희 ( Young Hee Cho ) 한국특수체육학회 2010 한국특수체육학회지 Vol.18 No.3

본 연구의 목적은 특수체육지도자들의 스페셜올림픽 참여경험이 교육신념에 영향을 미치는지를 규명하는데 있다. 특수학급 교사, 사회복지기관의 특수체육 담당교사와 지도자 300명을 대상으로 설문 중 참여자 108부, 비참여자 111부, 총 219부 설문지를 분석하여 자료처리 하였다. 본 연구에서 사용된 조사도구는 Spodek(1985)의 신념분류기준과 Peters 등(1985)이 제시한 신념측정도구(Beliefs Test Inventory)와 최선미(2001)와 임종미(2005)의 교육신념에 관한 연구에서 사용된 설문지를 중심으로 본 연구의 목적에 알맞게 수정, 보완하여 사용하였다. 자료 분석 방법으로 수집된 자료의 통계처리는 SPSS 12.0 Version을 활용하여 빈도분석, 독립표본 t-test, 일원변량분석을 실시하였다. 연구결과는 다음과 같다. 첫째, 특수체육지도자의 스페셜올림픽 참여에 따른 교육신념은 스페셜올림픽에 참여한 집단이 비참여 집단에 비해 교육신념이 높게 나타났고, 하위요인은 성숙, 행동, 상호작용 순으로 높게 나타났다(p<.001). 둘째, 스페셜올림픽에 참여한 특수체육지도자의 일반적 특성에 따른 교육신념을 살펴보면, 성별에 따른 교육신념은 남자가 여자에 비해 높게 나타났고, 하위요인 중 행동주의에서만 유의한 차이가 나타났다(p<.05). 특수체육 전공유무에 따른 교육신념은 특수체육 전공한 지도자가 비전공자에 비해 높게 나타났고, 하위요인 중 상호작용에서만 유의한 차이가 나타났다(p<.01). 지도경력에 따라서는 3년 이하-5년 이하의 경우 교육신념의 정도가 높게 나타났으나 5년 이상에서 낮아졌다. 근무시설에 따른 교육신념에서는 특수학교가 사회복지시설, 일반학교 특수학급에 비해 높은 교육신념을 나타냈다(p<.05).셋째, 특수체육지도자의 스페셜올림픽 참여횟수가 많을수록 교육신념이 높은 것을 알 수 있었으며(p<.05), 하위요인별로는 성숙과 행동주의적 교육신념에서 6회 이상 참여한 특수체육지도자의 교육신념이 가장 높게 나타났다(p<.01). 또한 스페셜올림픽에 참여한 특수체육지도자의 대회규모에 따른 교육신념에서는 국내, 국제대회에 모두 참여한 특수체육지도자들의 교육신념이 가장 높게 나타났고, 교육신념의 하위요인별로는 성숙과 행동주의적 교육신념에서 또한 국내, 국제대회에 모두 참여한 특수체육지도자들의 교육신념이 높게 나타났다(p<.01). The purposes of this study was to investigate how adapted physical education teachers and instructors` participation in Special Olympics influences their educational faith. The subjects of this study were 219 adapted physical education teachers and instructors of special school, special class and welfare center, including 108 who participated in special olympics and 111 who did not. The research tools employed by this study include Spodek(1985)`s categorization of beliefs, the Beliefs Test Inventory by Peters(1985), and the questionnaire used in Choi Seon-mi`s 2001 study, modified from the original questionnaire used in some past studies on educational faith (Oh Chae-seon, 1990; Han Ji-hye, 1992; Heo Hye-gyeong, 1994; etc.) to suit adapted physical education instructors. For statistical analysis of the collected data, the SPSS 12.0 statistical package was used for frequency analysis, independent sample t-test and one-way ANOVA. The results of the analysis were as follows; First, those who had participated in Special Olympics showed a higher level of educational faith than those who had not. Among the sub-factors of educational faith, maturity, behavior, and interaction were found to be relevant, with a statistically significant difference (p<.001). Second, no significant differences were observed among the Special Olympics-experienced adapted physical education instructors with respect to age. As for the college major of the participant, those who majored in adapted physical education exhibited a higher level of educational faith, but the difference was not statistically significant. Among the sub-factors of the educational faith, only interaction was found to be statistically significant (p<.01). With respect to the length of experience, the participants with 1 to 5 year experience showed an increase in their educational faith, but the level of faith was found to decrease after 5 years. In regard to the facility type, those working at special schools showed a higher level of educational faith than those working at welfare facilities or those teaching special classes within regular schools, with a statistically significant difference (p<.05). Third, the analysis revealed a statistically significant increase (p<.05) in educational faith proportional to the number of times each instructor had participated in Special Olympics. As for the sub-factors of educational faith, a significant difference was observed in maturity and behavior of those who had participated in Special Olympics 6 times or more (p<.01). There was no significant difference in interaction. As for the size of the event, those who had participated in both domestic and international events demonstrated a higher level of educational faith while those who had participated only in international events were found to have the lowest level of educational faith (p<.01). The instructors with both domestic and international Special Olympics experiences were also found to be higher in educational faith in terms of maturity and behavior (p<.01) while no significant difference was found in terms of interaction.

經濟作物 改良을 위한 遺傳工學 技術의 開發 : I. Nicotiana PlumBaginifolia의 葉肉細胞에서 原形質體 裸出과 再分化 I. Protoplasts isolation from leaf mesophyII cells of Nicotiana plumbaginifolia and regeneration

蔡永岩,崔奎煥 서울大學校 農科大學 1985 서울대농학연구지 Vol.10 No.1

Various innovations for the genetic modification of plants are being investigated in aiming to produce new varieties that can not be made by the conventional plant breeding scheme. One of the most promising approach in plant transformation is to introduce new genes into plant protoplasts and regenerate these protoplasts into whole plants with new improved characteristics. Before embark directly on a target economic crop, however, it seems a right way to establish firstly the feasibility of the protoplast approach in a model plant species where the cycle of plant to protoplast to plant is well established. When the protoplast approach was worked beautifully on the model species, then this technique would be extended to a economic crop with its difficulties in plant regeneration from the protoplasts. This report describe the procedures established through a serious of experiments for the optimum growth and regeneration conditions of the protoplasts isolated from Nicotiana plumbaginifolia leaf mesophyll cells.

Objects : Many studies have demonstrated greater frequency of soft neurologic signs in patients with schizophrenia than in controls. However, factors associated with chronicity,institutionalization, individual differences and neuroleptic medication make it difficult to interpret these results. We report on our ongoing study of soft neurologic signs and their relationship to neuroleptics and institutionalization in schizophrenia. Methods : Soft neurologic signs were examined with a standardized instrument, Neurological Evaluation Scale- Korean Version(NES-K) in 11 neuroleptic-naive patients with schizophrenia, 17 neuroleptic-treated patients and 14 chronically institutionalized patients. Results : Scores of total items(p<0.05), sensory integration(p<0.05), sequencing of complex motor acts(p<0.05) and others(p<0.01) functional areas of NES-K were significantly different among three groups. There was no difference in the area of motor coordination. Posthoc analysis showed that scores of total items(p<0.005) and sensory integration areas(p<0.01) of NES-K were significantly higher in the institutionalized patients than those of neurolepticnaive group. However scores of sequencing of complex motor act and others categories were not different in the institutionalized and neuroleptic-naive patients. Conclusion : These findings suggested that neuroleptic treatment or chronic institutionalization might partially affect soft neurologic signs, especially sensory integration area, in patients with schizophrenia. However, the soft neurologic signs of motor coordination area could be a biological trait marker of schizophrenia independent of confounding variables.

채규성,김창우 경희대학교 레이저공학연구소 2006 레이저공학 Vol.17 No.-

Two types of SiGe HBT MMIC double balanced frequency up-converter have been fabricated to compare linearity improvement : one using a gilbert-cell configuration with an emitter degeneration resistor and the other using a conventional gilbert-cell configuration. The frequency up-converter chips were fabricated using STMicroelectronics' 0.35 ㎛ Si-BiCMOS process. The frequency up-converter with an emitter degeneration resistor produces a P_(1-dB) of -10.5 dBm with a conversion gain of 10.5 dB, while the frequency up-converter without same resistor produces a P_(1-dB) of -14.7 dBm with a conversion gain of 16.3 dB. The frequency up-converter with a emitter degeneration resistor exhibits higher linearity than the conventional one.

This thesis is to present a useful data on accounting problems of changing prices that should be considered as the suitable accounting system of business society in Korea through the analysis of the accounting systems of changing prices in the United States. Especially, this thesis intends to regard the developing process and current status of an accounting systems of changing prices through the following statements. 1) APB Statement No. 3 issued by the Accounting Principles Board. 2) ASR No. 190 issued by the Securities and Exchange Commisson. 3) SFAS No. 33 and No. 82 issued by the Financial Accounting Standards Board. ASR No. 190 and SFAS No. 33, No. 82 are the pronouncement of the accounting systems of changing prices that are currently employed in the United States. But it seems to be replaced by uniform standards by the researches of the Financial Accounting Standards Board. The Basic guidelines of the SFAS No. 33 and No. 82 which were issued by the FASB summarized five categories : (1) considerations of special industry problems, (2) measurement of current cost by indexing and direct pricing, (3) miniature of the disclosure scope of supplementary information relating to changing prices(e.g., inventories, tangible assets, cost of good sold, depreciation), (4) presentation by separate item on holding gain or loss, (5) presentation by separate item on general purchasing power gain or loss. Therefore, it seems that applicability and usefulness of accounting information on suggested accounting systems of changing prices were taken into account as significant factors by the FASB. As balance sheet is excluded from supplementary information that should be disclosed, it is difficult to observe the financial status of an enterprise that has reflected the effects of changing prices.
