치환에 의해서 야기되는 Benzene ring의 변형에 관한 고찰

서정선,조정랑 명지대학교 1978 明大論文集 Vol.11 No.-

The small deformations induced by subtitution in the skeletal geometry of the benzene ring are analysed in detail in a number of monosubstituted benzene derivatives. It is shown that the available structural data, which come mainly from room Temperature X-ray diffraction experiments, are unsuitable for a detailed investigation of the bond length distrbution within the ring, because of the effects of the thermal motion. They are suitable, however, for a study of the internal bond angles. The observed dependence of the ring geometry upon the σ-electronwithdrawing or-releasing properties of the substituent and the extent of its conjugation with the ring is discussed in terms of ① hybridization effects at the carbon atom at which substitution takes places ② valence shell electron pair repulsions ③ intramolecular non-bonded interactions, and ④ coulombic attractions between formally charged atoms. If appears that the experimental evidence is best rationalized in terms of either hybridization changes or valence shell electron pair repulsions.

남랑균,임수원 경북대학교사범대학부속 중등교육연구소 2005 중등교육연구 Vol.53 No.1

본 연구는 대도시, 중 · 소도시, 농 · 어촌 지역의 중 · 고등학교 남 · 여학생들을 대상으로 학생들의 여가의식을 분석함으로써 청소년들이 여가를 어떻게 활용하고 있는지 실태를 파악하고, 또 앞으로 전면적인 주5일 수업제 시행시 바람직한 청소년 여가문화의 정착을 위한 기초자료를 제공하고자 하는데 그 목적이 있다. 이러한 목적을 달성하기 위해 대구광역시와 경상북도에 위치한 중 · 고등학교에서 편의추출법으로 남 · 여 480명을 집락표집하여 설문지조사를 실시하였으며, 수집된 자료의 분석을 통해 도출된 결과는 다음과 같다. 첫째, 현재 학생들이 가장 많이 참여하고 있는 여가활동은 스포츠 부문과 관람 감상 부문이었다. 둘째, 여가활동 불만족 이유로 시간적 여유가 없다는 답변이 높게 나타났는데 이는 학생들이 대부분의 시간을 학교생활 학업 보충활동에 소비하고 있기 때문이라고 생각된다. 셋째, 주5일 수업제 하의 여가활동의 필요성에 대해서는 긍정적인 답변이 대체적으로 많았는데 이것은 주5일 수업제로 인해 여가 시간이 많아짐으로 여가활동을 할 수 있는 여유가 생길 것이라는 기대감에 기인 한 것으로 보인다. 넷째, 주5일 수업제에 따른 여가활동 참여 이유로 심신의 휴식과 스트레스 해소를 위함이라는 응답이 높게 나타났는데 이는 학교의 정규 과정과 학원 등에서의 학업으로 인하여 청소년들이 여가활동을 할 시간적 여유가 없다는 것에 기인 한다. 다섯째, 주5일 수업제 시행 시 여가활동 참여시간 투자 여부에 대해서는 긍정적인 답변이 대체적으로 많았는데 이를 통해서 학생들이 앞으로 심신의 휴식과 스트레스 해소, 자아발전을 위해 많은 시간을 여가활동에 투자할 것이라고 예상할 수 있다. The purpose of this study is to research the consciousness of adolescents in metropolises, small towns and rural districts to identify the actual conditions of their leisure participation and analyze their consciousness of leisure time for the upcoming Five-day-work-week School System. The data was acquired from total 480 middle and high school students in Daegu Metropolis and Kyungsangpook Province. Among them, 240 were boys and 240 were girls. They were selected by the convenience sampling method. For data analysis, frequency analysis and chi-square with SPSS Window 10.0 Version Program were used. From the analysis of the data, the following conclusions were obtained; It was found that the most popular two leisure activities were doing sports games and going to the movies. The answers to the need for leisure activities under the five-day-work-week system were mostly positive. Under that system, students can have more leisure time and it seems that their anticipation for the increasing leisure time results in positive attitudes toward leisure activities. Under that system, facilities for physical training and recreation are strongly needed so it is essential to establish infrastructure for education and social welfare and ask for support of other organizations that has leisure facilities. Finally, it is needed to improve leisure facilities and programs so as to execute the conclusions from the analysis and make the most use of the increasing leisure time according to the five-day-work-week.

木材의 맞춤 技法에 關한 硏究

申朗浩,金政虎 三陟大學校 1998 論文集 Vol.31 No.3

목재의 접합이란 목재가 지니고 있는 단점을 보완하는 방법 중의 하나로서 각각의 기능이나 용도에 맞게 두 개 이상의 부재를 이어서 한 개의 부재로 접합하는 것을 이음이라 하고, 각각의 부재를 쓰임에 따라 직각 또는 경사지게 맞추는 방법을 맞춤(짜임)이라 한다. 가구나 건축에서의 맞춤은 그 정밀도에 따라서 제품의 수명도 달라지고, 같은 조건에서도 어떤 맞춤 방법을 사용하느냐에 따라 제품의 아름다움이나 질이 달라지므로 맞춤의 기법을 공정과 함께 세부적으로 인지하고 있어야 한다. 목재의 접합은 일정한 강도를 유지하는 것 외에도 힘에 대한 변위(變位)가 적어야 하며, 적절한 강성을 지녀야 하는데 구조재에 작용하는 압축, 인장, 전단 등의 응력을 파악하고 맞춤 하고자 하는 장소와 부재의 구조 방법에 따라 적절한 기법을 선택하여 사용하여야 한다. 이러한 의미에서 본 장에서는 맞춤 기법의 종류와 사용 방법 공정 등에 대하여 연구하고, 나아가 맞춤에 사용되는 공구류에 대하여도 세부적으로 살펴본다. The technique of joining is one of the most effective methods for the correction of shortcoming of woods. According to the function and the uses of it, it has two different main types. One called 'connection' is a method which is used when we want pur at least two boards together side by side, and another called 'joint' is used when we put pieces of wood together at the end of pieces at a right angle or slant. An accurate joint can make all the difference in the life span of furniture and architecture. Even though all the conditions are the same in processes, the appearances and the qualities of outcoming can be very different by the types of joint that is used. So, it is necessary to know about all the details of joining techniques along with the processes of wood working. Because joints are the places where the structures of furniture or architecture should be properly selected according to the factors like the compression stress, the expansive stress, and the conductivity of each constructions. In these senses, in this chapte, we'll study more about all the different types and the processes of joints and we'll get more specified information about tools for joining techniques as well.

申朗浩 三陟大學校 1998 論文集 Vol.31 No.3

The development of craftworks that is based on the beauty of tradition with the life and spirit of a nation and that takes the modern life style into cosideration not only paves the way for the restoration of the vein of a vanishing tradition of craft but also gives an opportunity to success traditional culture. However, the abandonment of principles and the thoughtless inflow of western culture in modern Korean history led the Korean traditional craft to a state of structural disorder, Besides, the lack of general understanding of tradition of Korean craft became a barrier to the development of traditional handcraft and even threatened the maintenance of its life. Today, the world is making efforts to find an active and diversified way of improvement of products by the intensification of the international competitive power through technical innovations, introductions of new materials and new designs. according to this tendency, we persue a renovation of living environment by the development of diverse materials and techniques with a renewed understanding of the traditional craft, but we still have a lot of problems in development of characteristic which is peculiar to the Korean traditional craftwork. In this point of view, it will be very significant outcome as a basis of succession of tradition and creation of new design if we can apply the traditional way of Korean Nacre Inlay lacquer Handcraft to the contemporary living environment and to the preference of people. In addition, we will be able to show a possibility to innovate products as an cultural things as well as the development of crafts to export for the national economy. Therefore, in this project. I pur an emphasis on the development of Korean Nacre Inlay Lacquer Handcraft through design based on the tradition, understanding of the origin, development, way of proceeding, material and techniques of it.

未成熟 흰쥐子宮의 Estrogen 受容體의 細胞內 分布 및 Progesterone 受容體에 對한 Tamoxifen의 作用

朴朗韻,鄭泰浩,曺準承 慶北大學校 醫科大學 1990 慶北醫大誌 Vol.31 No.3

Estrogen의 작용은 세포내의 특이수용체와의 결합을 통해 특정유전자의 발현을 유도함으로써 이뤄진다는 정도로 밝혀져 있을 뿐 그 자세한 기전에 대해서는 잘 이해가 되지 않고 있어 estrogen 및 항estrogen의 표적조직내 존재여하에 따른 estrogen수용체의 세포내 분포에 대해서 알아보고자 하였다. 미성숙 흰쥐에 100㎍의 tamoxifen을 일회 투여하고 2, 6, 12, 24, 48, 72시간이 지난 후에 자궁에서 나타나는 변화를 살폈다. 자궁무게와 자궁내 DNA함량, 그리고 progesterone수용체의 함량은 tamoxifen투여후 시간이 지남에 따라 모두 증가되었다. Tamoxifen을 투여하지 않은 대조군에서의 estrogen수용체 핵과 세포질에 각각 50%씩 분포하였고 tamoxifen투여후에는 세포질내수용체가 점차 감소하고 핵내수용체는 증가되는 경향을 보였다. 또한 대조군에서는 거의 모든 수용체가 유리형으로 존재하였던데 반해 tamoxifen의 투여로 결합형 수용체의 증가와 함께 유리형의 감소가 초래되었다. 이상의 결과로써 미성숙 흰쥐 자궁세포내에는 핵과 세포질 모두에 유리형 수용체가 존재하며, tamoxifen은 이들 양 분획의 수용체에 모두 결합하고 세포질내에서 핵내로 수용체의 전이를 유발하며 동시에 새로운 수용체의 합성도 유도하는 것으로 사료된다. Although it is widely accepted that specific intracellular receptor proteins are involved in the estrogenic regulation of gene expression and growth in reproductive tissues, the precise nature of the regulation is poorly understood. Among the unresolved issues are the distribution and dynamics of the estrogen receptor protein in target tissues in the presence and absence of estrogens and antiestrogens. In this study, the effect of antiestrogen, tamoxifen, on subcellular distribution of estrogen receptor in immature rat uterus was determined. A single dose of tamoxifen(100㎍/rat) increased uterine wet weight, DNA content, and cytoplasmic progesterone receptor content 2, 6, 12, 24, 48, 72 hours after injection. Total estrogen receptor content progressively increased, peaked 48hr post-injection, while cytoplasmic receptor content decreased. In control uteri, nuclear estrogen receptors were almost unoccupied, but occupied receptors increased afrter tamoxifen treatment. The amount of unoccupied cytoplasmic receptors rapidly decreased 2hr postinjection and then gradually restored to that of control which was 74% of cytoplasmic receptors. These results suggest that in immature rat uterus both cytoplasm and nucleus contain unoccupied, free estrogen receptors and also suggest that tamoxifen can bind both cytoplasmic and nuclear 'estrogen receptros, increase total estrogen receptor content, and elicit some estrogenic effect.

나날이 발전해가는 경제성장과 더블어 한층 심각해져만 가는 환경오염을 피부로 느끼면서 생활하는 현대인들은 누구나가 자연 그 지체로 돌아가고 싶다는 마을을 가지리라 생각한다. 근본적인 자연 그 자체로 들어가지 못하는 마음을 현대 생활속에서 항상 접하는 어떠한 물건에서 찾는다면, 그것은 바로 인간에게 가장 자연스러운 친금감을 주는 재료인 나무로 만들어진 제품이라 하겠다. 즉, 목재는 역사가 시작된 이래 부드럽고 따뜻하며 자연스런 친금감을 준다는 질감의 특성으로 인하여 인간과 더블어 가장 밀접한 관계를 계속 유지해 왔다고 볼 수 있다. 따라서 예부터 우리나라에서는 삼면이 바다로 둘로 싸여 있고, 남북으로 길게 위치해 있다는 지리적, 위치의 특성으로 인하여 수종이 매우 다양하고 풍부하였다. 그래서 이러한 목재는 가구재나 건축재로 많이 사용되어져 왔다. 그러나 새로운 건축자재가 다양하게 발달됨으로써 목재의 사용 용도 또한 건축용재에서 장식용재 및 공예재료로 차츰 전환되어 가고 있다. 이러한 의미에서 우리가 쉽게 접할 수 있는 목재의 종류와 구조 및 성질에 관하여 연구하고, 더믈어 목재를 기본 재료로하여 만들어진 새로운 재료의 특성 및 종류에 관하여 살펴본다. Almost every modern people who is living a life getting the feel of environmental polution wit the skin that is worsening in line with the increasing economic growth, is believed to have a great mind to return to nature. If we can suggest an object which is touched in everyday life the moderns with who can not return to the orginal nature, it will be works made of wood which gives a feeling of intimacy to human beings. That is, wood is regarded to have had a close relationship with man due to its characteristic that have produced friendly feelings to man since the begining of human history. Accordingly, owing to the geographic character of our country that is surrounded by sea on all sides but one and stretches from south to north, it abound with and has a variety kind of wood. So such woods have been used as materials for building and furniture. But in accordance with various development of new building materials, the use of wood have undergone a change from the materials for building to the ones for decoration and craftwork. In this respect, the kinds, structure and character of wood which is easily touched with us, is studied and the special character and kinds of new materials that are made on the basis of wood, are examined.

沙土에 있어서 감자栽培의 生態的 調査硏究

李瑯雨 대구교육대학교 1974 論文集 Vol.10 No.-

Raising crops have been so far impossible on the sandy soil of rivers. But the results obtained from this test has shown that growing crops on such soil are possible with the help of chemical fertilizer and plant growth hormone through the crops thus raised are not so good in quality and quantity as those raised on the ordinary plough land. It is expected that continuing study will bring about better effect on both quality and quantity.

華角工藝를 利用한 工藝品 開發에 關한 硏究

申朗浩 三陟大學校 1993 論文集 Vol.26 No.-

Among traditional craft arts in Korea, Wha-Gak handicraft is recognized as an orgianl craft art, because its material has been improved and developed. The author attempted to find out its historic and social background and production processes through boks and trial manufacture. The author tried to recognize its value as a traditional craft arts. As for Wha-Gak handicraft , it is intially made by sheets of thin horn paper. On this paper, various patterns are drawn with colors and attached on the object as a decoration. It was influenced by ancient Chinese Dae-Mo-Bok-Chae technique and it is estimated that these days horn paper is used instead of Dae-Mo as a main material. The oldest remain that we know are produced during the Silla Dynastry and kept at Jung Chang Won in Japna, The essence of color on Wha-Gak handicraft is pattern design and the horn paper. Judhing from patterns and colors on the remains we can understand that popular belief and story have been shaped and symbolized in limited areas. Chinese color, gold and silver foil have been used and flowers, longevity symbols, dragons, tigers, magpie tigers and jumping carps seen oncfolk painting and embroidery have been repeatedly described on the remains. These old remains are feminine articles such as sewing boxes, mirrors, Korean socks case, combs, fans, jewelry boxes and sewing measures. The reason why this Wha-Gak handicraft has been developed so slow is that its production process was difficult, it was restricted because it was regarded as aristocratic craft arts and remains could not be spread out because of horn paper's weakness. I think that recently production problems are solved by recognition of traditional craft arts, mechanized production of horn paper and development of tools.

복수내 Fibronectin, Adenosine Deaminase, Sialic Acid 및 지질의 감별진단적 의의

여승엽,박낭운,조준승 慶北大學校 醫科大學 1990 慶北醫大誌 Vol.31 No.3

복수를 일으키는 질환의 감별진단에 사용하기 위하여, 복수액에서 몇가지 생화학적 지표를 측정하고, 각 지표들의 감별진단적 의의를 검정하여 보았다. 총 39명의 환자로부터 복수액을 채취하였는데, 그 중 16명이 악성종양, 5명이 결핵 그리고 18명이 간경변증 환자였다. Fibronectin과 sialic acid치는, 악성종양성 및 결핵성복수에서 간경변성복수에 비해 각각 유의한(p<0.01) 차이를 나타내었으나, 악성종양과 결핵 사이에서는 유의한 차이를 보이지 않았다. Adenosine deaminase치는 악성종양성, 결핵성 및 간경변성복수 모두에서 서로간에 유의한(p<0.01) 차이를 나타내었다. 또한 복수내 백혈구수, 단백질농도, 포도당농도, lactate dehydrogenase, 지질농도등 기존 생화학적 지표들이 측정치의 분포에 있어 이들 세군 사이에 상당한 중복을 나타낸 반면에 fibronectin, sialic acid, 그리고 adenosine deaminase측정치의 분포는 각각 세군 사이에 명확한 차이를 보여주었다. 이상의 결과로 미루어보아 복수액에서 fibronectin, sialic acid 및 adenosine deaminase를 측정함으로써 원인질환의 감별진단이 더욱 용이하고 정확하게 되리라 사료된다. Trying to find accurate markers to differentiate ascites, several biochemical parameters were measured in ascitic fluids. Ascitic fluid samples from 16 patients with maligancy, 5 patients with tuberculosis and 18 patients with liver cirrhosis were investigated. The levels of fibronectin and sialic acid were significantly higher in malignant and tuberculous ascites than cirrhotic ascites(p<0.01) but showed no significant difference between malignant and tuberculous ascites. The activities of adenosine deaminase in malignant, tuberculous and cirrhotic ascites were significantly different from one another(p<0.01). Fibronectin, sialic acid and adenosine deaminase did not show the significant overlaps among 3 groups while several other parameters-leukocyte, protein, glucose, LDH and lipids analyzed simultaneously in theses samples showed the considerable overlaps. These results suggest that determinations of fibronectin, sialic acid and adenosine deaminase in ascites may improve the accuracy of differential diagnosis of ascites.
