        본 연구는 가시부 전영역에 감광하는 전자사진용 감광체를 만들기 위하여 400nm부근에 흡수파장을 갖는 sunfast yellow와 700nm부근에 흡수파장을 갖는 α,β-copperphthalocyanine의 색소를 산화아연(ZnO)에 흡착분산시켰다. 각종 결합제(Binder)의 감도와 , 산화아연과 결합제와의 조성비에 따르는 변화실험의 결과 5.5:1에서 가장 좋은 결과를 나타냈다. 전자사진 감광체의 적합성을 확인하기 위하여 정전특성과 분광감도를 측정해 본 결과 sunfast yellow와 β-copper phthalocyanine을 혼합사용한 것이 가장 좋은 감도를 나타냈으며, 이 때 측정된 전자시진감도는 E1:2=1440 luxㆍsec이었다. 또한 분광감도 측정결과는 가시부전역에 걸쳐 감도를 감광체임을 확인하였다.

        To examin ripening in peach types, cell wall contents and Polygalacturonase activity were compared in Changbang, Daegubo and Yumyung peaches. Among peach types, the hardness of Daegubo was the lowest. Yumyung peach had the highest content of alcohol-insoluble substances and Changbang peach of cell wall. The contents of total and insoluble pectic substances were little different between Changbang and Yumyung peach, while the lowest in Daegubo. Daegubo peach had the highest activity of polygalacturonase, Changbang and Yumyung peach in succession.

        Toxohormone-L is a lipolytic factor, found in ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. A substance that inhibited the lipolytic action of Toxohormone-L was isolated and purified from Korean red ginseng powder. This substance had a pectin-like a 1, 4-polygalacturonan backbone with some acetoxyl groups, and so was an acidic polysaccharide. It inhibited Toxohormone-L induced liploysis in a dose dependent manner at concentrations higher than 10㎍/㎖. Purified acidic polysaccharide yield(PG_4-3 and PG_4-4 fraction) was about 0.03%. And also pectic acid that inhibited the lipolytic action of Toxohormone -L.

        The population variation of Spanish mackerel (Scomberomorus niphonius) according to its major prey abundance was analyzed using monthly catches of coastal set net fisheries in the southern waters off Gyeongsangnam-do and eastern waters off Gyeongsangbuk-do of Korea from 2006 to 2019. The abundance of Spanish mackerel and its prey species fluctuated almost simultaneously with time lags of +2 to -2 months between the set net fisheries in the southern and eastern waters. The generalized additive model revealed that the abundance of Spanish mackerel was influenced by its prey species such as hairtail and anchovy in southern waters, and common mackerel and horse mackerel in eastern waters. The model deviance explained 49% and 42% of Spanish mackerel abundance in southern and eastern waters respectively. These results suggest that the abundance of Spanish mackerel is affected by seasonal migratory prey fish species in the coastal areas and can be linked to their northerly migration.

        한국의 전통적인 민간 약재로 사용되어져온 흰민들레의 잎절편체로 부터 기관형성을 통한 재분화를 시도하였다. 잎 절편체를 BA (0-4mg/L)와 2,4-D (0-1mg/L)가 혼합 첨가된 MS 기본 배지에 치상하여 배양한 결과, 배양 3주후부터 신초가 발생되었다. 신초 분화율은 2mg/L BA 첨가된 조건에서 가장 높았으며, 배양 4주째 4mg/L BA 첨가된 조건에서는 캘러스가 유기되었다. 잎령에 따른 부정아 형성율, 발생빈도, 건량, 생중량을 조사한 결과, 발아 후 7주된 잎 절편체에서 평균 11.5개의 신초를 형성하였다. 유도된 신초는 0.5mg/L NAA가 첨가된 배지에서 발근되었으며, 화분에 옮겨 완전한 식물체로 재분화 되었다.

        본 연구는 전통사회 관련 아동교육 학위논문을 대상으로 하여 연도별로 연구수량, 연구내용, 연구방법을 분석하여 전통사회 관련 아동교육 학위논문의 연구경향을 구체적으로 알아보는데 목적이 있다. 연구결과 첫째, 학위논문의 연구수량은 제1기와 제2기에는 연구의 수량이 적었고, 제6기와 제7기에 급격히 증가하였다. 둘째, 연구내용은 초기에는 아동교육에 대한 연구가 많았고, 제6기와 제7기에는 전통문화교육의 인식과 실태, 전통문화교육 프로그램 및 학습법 개발, 전통문화교육의 효과에 대한 연구가 크게 증가 하였다. 셋째, 연구방법은 제1기와 제2기에는 문헌연구, 조사연구, 실험연구가 주로 사용되었고, 제5기부터 연구방법이 다양해지면서, 제7기에는 실험연구, 개발연구가 크게 증가하였으나, 내용분석은 감소하였다.

        Young-Soon Kim. 2001. Discourse Functional Interpretation of the Word Order Variation. Studies Modern Grammar 24, 137-159. In many linguistic studies there has been a dichotomy between formal and functional approaches. This paper will attempt to connect the two approaches because linguistic expressions always simultaneously have formal grammatical properties and functional pragmatic properties. In order to do it, this study explains the concept of the discourse-grammar, demonstrates the discourse-grammar relationship of Korean, German, and English, and deals with the motivation of word order variation in English. There are expressions of discourse functions in English, for example, the left attachment and the right attachment. The former has the interpretation of marked topicalization and the latter has the effect of creating a new focus of statement. The outline of results in this study is as follows: Korean and German are pragmatical languages, which make use of grammatical means to cope with discourse-functional requirements in quite a different way from English.

        Lim, Ji-Ryong & Young-Soon Kim. 1999. The Integration of the Signification and the Semiosis. Studies in Modern Grammar 18, 129-196. This study handles two important semiotical concepts, i.e., signification and semiosis, within the framework of theoretical semiotics. We have called the academic field `semiotics` as a science of signs, which consist of two elements like the signifier and the signified. According to Saussure (1916) and Hjelemslev (1943), the signified means a mental meaning and the signifier means its material. In general, the signification can be understood as the connection of mental meaning with its material and the semiosis as the process of signs. For Peirce (1931/1935) the semiosis means the action, of signs which must be interpreted. The signification and semiosis seem to be not conceptional differentiated, but correlated with each other. In this study we attempt to find out the clear interaction between the signification and the semiosis. Moreover, on the basis of this interaction we propose the integral semiotic program for the communication, which is composed of signification and semiosis.
