이 연구의 목적은 중학교 과학 수업에서 교사와 학생간의 언어적 상호작용이 실제로 어떻게 이루어지고 있는지를 관찰ㆍ분석하여 이에 대한 특징을 추출함으로써 과학 수업에서 교사와 학생간의 언어적 상호작용에 대한 기초 자료를 제공하는데 있다. 이를 위해 수업 분석 준거를 개발하였으며, 8명의 과학 교사의 수업 12차시를 관찰 및 녹화하였으며, 교사와의 면담을 실시하였다. 수업 분석 결과, 관찰한 과학 수업에서 교사와 학생간의 언어적 상호작용은 주로 교사의 단순 확인/기억 질문, 학생의 단답형 응답, 교사의 즉각적 피드백이 주를 이루었다. 교사가 사고 질문을 하고 지연 피드백을 부여 하는 경우 학생들이 자신의 생각을 드러내고 이를 기반으로 사고를 진전시켜 나갈 수 있었으나 이러한 사례는 그 수가 상당히 적었다. 교사들은 학생들의 사고를 유발하고 이를 진전시키기 위한 노력보다는 수업 내용을 논리적 흐름에 맞추어 체계적으로 제시하는 것에 더 큰 중점을 두는 경향이 있었다. 또한 관찰한 수업에서 교사가 시범 실험, 모형 혹은 실물 수업자료 등을 활용할 때 보다 많은 수의 학생들이 적극적으로 수업에 참여하여 자신의 생각을 드러내었으나 교사가 학생들의 생각을 바탕으로 학생들의 사고과정을 진전시켜 나가는 과정을 도모하지 않음으로써 학생들의 사고과정을 단절시키는 경우가 많았다. 따라서 수업 활동과 수업 자료 활용이 효과를 거두기 위해서는 각각의 활용에 있어서 학생들과 구체적으로 어떠한 상호 작용을 형성해야 하는지에 대해 연구가 이루어져야하며, 또한 교사는 교사의 질문이나 피드백이 학생들의 학습에 중요한 역할을 함을 인식해야 한다. The purpose of this study is to analyze verbal interaction between teachers and students in order to collect qualitative data on the characteristics of the interaction to enhance teaching efficacy. Total of 12 classes of eight science teachers were observed and were interviewed. The classes were video taped and all the verbal interactions were transcribed. The transcribed content and interviews were further analyzed to draw any conclusions on the verbal interaction between teachers and students. Analysis criteria for the data on the class and interview were developed based on the literature review and applied to analyze the collected content. The analyzed data showed that verbal interactions composed of confirmation questions for memorization, students' short responses and teacher's immediate feedbacks. The results of the study also suggested that there needs to be further studies on the interactional techniques for teacher in utilizing the class materials and activities. The teachers should acknowledge the importance of the questions and feedbacks of teachers for students to stimulate their sound learning through literatures.

팔당호의 생태학적 환경요인의 계절적인 변화를 분석하므로서 이것으로 인한 식물성 플랑크톤의 연관성을 고찰과 함께 오염과정을 파악하여 수질오염의 예방의 기초자료를 얻고자 본 실험을 수행하였다. 1994년 4월부터 1995년 10월까지 계절별로 3개 지점에서 시료를 채취하여 표층부와 저층부의 수질을 분석하였다 용존산소(DO)와 pH는 각각 7.0-11.6 ㎎/ℓ와 6.9-8.9의 범위이었으며 COD와 BOD농도는 각각 1.6-4.8 ㎎/ℓ와 0.8-2.9 ㎎/ℓ이었으며,SS는 1.8-8.6 ㎎/ℓ의 농도차를 보여 주었다. 또한 NH₃-N와 PO₄-P의 농도는 각각 0.161-0.478 ㎎/ℓ와 0.003-0.073 ㎎/ℓ이었다. 표층의 chlorophyll a의 농도는 낮게는 북한강 유입부위인 12.3 ㎎/ℓ로부터 가장 높은 경안천 유입부위 23.8 ㎎/ℓ의 범위를 보여주고 있다. pH,전도도, COD, BOD, SS ,총인, chlorophyll a의 농도는 하계절에 가장 높았으며 이 결과로 미루어 보아 하계절에는 하천에 오염물질이 가장 많이 유입되는 것으로 추정된다. Station별로 조사한 결과 이들의 농도는 경안천 하류인 St. 3가 남한강 하류인 St. 2이나 댐지역의 St. 4보다 높은 결과를 보여 주었으므로 경안천 상류에서 오염원이 가장 많이 유입되는 것으로 추정된다. 아울러 종속영양세균의 분포도 경안천이 다른 지역보다 가장 높게 나타났다. Seasonal variation of water quality was examined in the reservoir, lake Paldang on Han River, the inlet stations from three rivers, North Han River, South Han liver, Kyung-An stream, and the station of dam area of the lake. Water samples were collected bimonthly from surface and bottom layers at four different stations of the lake Paldang from April 1993 to August 1994. With respect to the seasonal variation, pH, conductivity, and concentrations of COD, BOD, SS, total phosphorus, and chlorophyll a were higher in summer compared with those of autumn or other seasons, while concentrations of DO, NH₃-N, and PO₄-P were increased in winter. Concentrations of COD, BOD, chlorophyll a, total nitrogen and phosphorus were the highest at the station of Kyung-An stream rather than those of other three stations. The average concentrations of chlorophyll a surface water were from 12.3 ㎎/ℓ at North Han River to 23.8 ㎎/ℓ at Kyung-An stream. Heterotrophic bacterial distribution showed higher at the station of Kyung-An steam than those of South Han River and the dam station of the lake.

This study examined the information and current trends of the study, which concern with the father's roles supposedly made impact upon the child development in Korea, by using the literatures written in Korea. The auther analysed the whole contents of the 108 literatures, mostly written for the last two decades from the 1970s, under the bases of the periods, the objects, and the methods of studies. The auther concluded the study as follows: 1. Year by year, the amount of the study has increased somewhat gradually, and the main topic been the schooling-aged children and adolescence. 2. The usual methodology among them was questionairing as to the cross-sectional approach and the positivistic survey;the tools used in the urvey were the writers' own studies and the previous materials that were newly translated or copy-read. 3. General contents in those studies were linked with father's appearance and disappearance or with his role-accomplishment:the variations can be summarised as personality, emotional, intellectual, and sex role development. The auther suggested that the new tools of studies fairly appropriate for Korean culture and the scientific technique to enhance the reliability of the study both required to develop for the further study in that field, and also that the multi-dimensional analyses, with father's role dimension and family systems deeply considered, by pervaded into the field.

최경순 服飾文化學會 1996 服飾文化硏究 Vol.4 No.2

The founding of ching costume system starts from the rule issued in second year of Te-chong reign that the clothing of Manchu people is prohibited to be chinesized. It has undergone many revisions and is officially established in the 37th year of Chien-lung reign. This study is Emperor's costumes during the year in chien-lung reign. The result are as follows: Emperor's costumes go to the travel are Chi-fu hat and Hsing -fu. Sea-dragon hat changes on otter skin or beaver hat and Ching-rong and ching-ni hat changes velvet hat. Light green informal wear is to be worn once a year. Name of sacrificial robes does not exist in Ching-hui-dien-tu but it take the place of Chao-fu I and Chao-dai II in Chuan dai dang-an. Sacrificial robes wear with indigo boots and the other cases wear blue boots and shoes and socks. The shape on ornaments in belt of sacrificial robes is tetragon stycle.

The strain producing biosurfactant was isolated from soil. The isolated strain was identified as the genus Tsukamurella through its morphological, cultural, physiological, menaquinone type, fatty acid composition characteristics. The highest biosurfactant production by Tsukamurella sp. 26A was observed after 4 days cultivation in the culture medium containing n-hexadecane 7%, NaNO₃0.2%, KH₂PO₄0.001%, K₂HPO₄0.02%, MgSO₄·7H₂O 0.02%, CaCl₂·2H₂O 0.02%, yeast extract 0.02%(pH 6.8-7.0, 30℃). The surface and interfacial tension of an aqueous solution reached 30 mN/m and 1.5 mN/m, respectively. The biosurfactant stabilized oil-in-water emulsion with a variety of hydrocarbones, edible oils and petroleum oils.

淸代 乾隆 42年《천대당안》服飾硏究

崔景順 服飾文化學會 1999 服飾文化硏究 Vol.7 No.5

Examine the dress which the Emperor actually wore in Gun-ryung 42nd year of Ching dynasty, comparison of 《Cheong-hoi-jeon-do》 with the Emperors year-round dress in Gun-ryung the 41st year was made and summarize the result as follows. It was used almost similar to the code of 《Cheong-hoi-jeon-do》. Though the materiasl, and colors were more diverse than those of the previous year, it seems that actual use of material was plain under the influence of mourning. All the materials for summer hat were rattans. And velvet was the material for the patrol hat, but actually used before they change to summer material after fur use was over according to the season, which can be said as more reasonable use than the code. Materials of coat were more diverse than the previous year and also they put on ko-hemp cloth which was not found in the previous year. This can be understood that they expressed their guilt-consciousness to the dead as dress material by wearing ko-hemp cloth during the summer after period of mourning was over. And they put on the ko-hemp, the Emperors ordinary dress, much longer time than the previous year and this seems to be coherent to the meaning of wearing ko-hemp cloth. They followed the Emperor's Jo-bok1 one for the Jae-bok which were not systematized and Jae-dae used Jo-dae2 as the Emperor's Jae-bok in 42nd year. This was the same as the Jae-bok code of the previous year. Jo-ju did not follow the code of 《Cheong-hoi-jeon-do》, but made a wide variety. For the belt, the same as 41st year, it marked the gem decoration style on the Jae-bok belt as a square type and the mourning dress by using the round type. The Emperors dress in 41nd year showed one side of the patrol clothes by the patrol of San-dong. On the contrary, it was also the chance to see one side of funeral garments in 42nd year. In Gun-ryung 42nd year, the Emperor put on the funeral garments for hundred days. Accordingly even in parts, we can see that the Emperor wore two kinds of dress for hundred days, that is, color dress and white dress. While on duty, in other words, everyday dress was only blue color and also the same clolr for the belt and shoes. But didn't put on Jo-ju. When they were in mourning, they wore white dress and belt as a funeral garments, which were called Hyo-bok, Hyo-bok.

조선조 가체논의와 그 요인

최경순 服飾文化學會 1996 服飾文化硏究 Vol.4 No.1

This study is concerned with the prohibition of False Hair(가체) and a primary factor in Lee Dynasty. Assuming that the trend of simplification in false hair is closely related to the idea of practical science to be the social and ideal background of those times, we researched. The results are as follows: Constant discussions and prohibitions against false hair were designed to differentiate between classes but to discard a cariety. Goge(고계) came to be a big problem during the reign of king Sung-Jong(成宗) and after on argument for the usage of false hair was in vogue king Young-Jo(英祖) and Jung-Jo(正祖). Finally the wearing of Hooge(후계) came to be a national regulation in manners and customs, and also brought the realization of prohibition against the usage of false hair. It is believed that the performance and the effect of the prohibition against the usage of false hair have a close relation with the idea of practical science.

아동-아버지 관계에 관한 연구(Ⅰ) : 영아-아버지 관계에 관한 문헌적 고찰

崔耕順 新羅大學校 1990 論文集 Vol.29 No.-

This study aims at emphasizing the importance of the paternal involvement in the social milieu of the infant. It is generally said that the paternal role, which we have considered in traditional contexts, is getting into change as time passes and social trends change, In this connection, we would like to make it clear, by using the numerous precedent studies in this field, that the experience in the infant-father interrelations/interactions contributes to the intellectual and societal development of the infant. By doing so, therefore, we would able to prepare the motivation to further the study on the infant-father relations which have long been overlooked in Korea. The results of the study can be summarized as follows: 1. The infant-father attachment development is influenced by the paternal early involvement in bringing-up(caregiving), preference, and sensitivity ; so as to enhance their ties, the earthier the contacts come, the more effective they become. 2. In the infant-father contacts, the infant preferred his/her father as the primary partner of the play, and the interactions through the infant-father play contributed to enhance the infant's intellectual and societal development. with the above results that were accumulated throught precedent studies, Ie wish to propose some points for the further studies in the field : First to consider the environmental variables of this family support-system which has great impacts on the infant-father interactions and second to grop for logitudinal study programs by adapting such various techniques as natural and operative experiments and investigations.
