The prominent malar region has been recognized a sign of youth and beauty in caucasian who generally have a dolichocephalic and long face. But in the orients, especially Koreans who generally have a mesocephalic or brachycephalic face, it is considered an agressive, unesthetic facial appearance. So many patients require the shaving of prominent malar eminence and arch, and many methods of its reduction have been devised. For the exposure of malar complex, infraorbital skin incision, intraoral approach, preauricular approach, supraauricular scalp incision, and coronal approach have been used. And for the reduction of bony structure, direct shaving, contouring and repositioning of the malar complex after extirpation, and medially fracture of zygomatic arch have been used with its own merits. We performed the reduction malarplasty through intraoral approach. After two parallel oeteotomy at medial part of the zygomatic bone, the midsegment is removed. The posterior arch of zygoma was bended or green stick fractured. When more correction was required, the posterior arch was fractured medially through the step incision at skin. This method has a some advantages. Compared with the method for extirpation of malar complex, the infection rate is diminished, the resorption is small because of no free bone graft. And cheek drooping is prevented. Compared with the method of coronal approach, the surgical trauma is minimal. Now we report some cases of reduction malarplasty performed through intraoral approach and disscus the surgical technique and results.

Elementary science textbooks are the major instructional materials which contain sceientific objectives to be acquired by students. The purpose of this study is to analyze the development system, to evaluate the inquiry activity in current elementary science testbooks, and to make suggestions for the improvement of them. The questionnaires were administered to 116 subjects that participated in development of the 5th elementary science textbooks, and 86 of the subjects responded. Based on the data gathered and analyzed in this study, the major findings are as follows. First, regarding the analysis and evaluation of elementary science textbooks. 1. The instructional objectives in elementary science textbooks are analyzed. The proportions of comprehension objectives is 38%, scientific inquiry process objectives 21%, experimental skills objectives 7%, scientific attitudes and interests objectives 4%. 2. The science concepts in elementary science textbooks of the 3rd grade required the preconcrete operational level(82%) and of the 6rd grade required the postconcrete operational level (73%) by J. Piaget. 3. The inquiry activities in elementary science textbooks are emphasizing gathering and organizing results and evaluation, and hypothesizing and designing an experiment. Inquiry index of the elementary science textbooks is 76. This is significantly higher than 35∼50 of America and U.K. 4. The number of questions per class hour is mostly three, and most of them require the students to explain phenomena in nature or in experiment Second, regarding the development system of elementary science textbooks. 1. The budget for and the period of the development of elementary science textbook should be expanded. 2. For the improvement of elementary science textbooks, more abundant resources and time should be used for the basic study and the field trial of textbooks. 3. The elementary science textbook must include the affective objectives as well as the scientific knowledges and scientific inquiry skills. 4. It is not desirable to assign equal number of pages to the content of physics, chemistry, biology, and earth science. 5. Closer cooperation system is needed among the ministry of education, development research center and the field trial schools.

In 1970's, a modern industrilization in Jeonbuk has been remarkably developed in the basis of ExportEnter-prise, aparted from the past various vulnerability, in addition to this, the authorities concerned have developed the Jeonbuk province into a positive industrial inclination, pursued after the Ho-Nam High way opening to traffic in the begining of 1970's. It has been expected for us to be Promising the hoped-for 1980's, because of not only turning the three city, that is, Jeonju, si and Kunsan into a development zone which can be a linking industrial belt but also enlarging the quadric street, Bun Yung into the biquadratic traffic road. We, herewith, have to grope the development industrial zone for promoting export project in Jeonbuk Province, under the basis of Export Orieoted System in 1980's. Judging such a thing from the foregoing view-point, I will name, in this preface, the complemental main-factor one by one as follows, except the general condition referred in the main discourse. 〈Promotive Guidance〉 ⓐ Utilizing the outer & inner information given by and overseas market movement groped for 〈example〉 Foreign marketing movement illustration meeting, Overseas superior goods display etc. ⓑ Improvement of the design and packing 〈example〉 Industrial design exposition, Display of the export commodity compared with ⓒ Enlargement of the administrative education for the Foreign Trade Practice. 〈Bringing up Scheme〉 ① Large-unit of the industrial factory belt. ② Modernization of the industrial facility. ③ Inducement plan of the foreign investor and drastic technical induction. ④ Making a industrial strategy and forming a relative industry to be induced 〈example〉 Establishment of the inter-related plant etc. ⑤ Backing up the positive government subsidy and inducing the public investment organization. Viewed with the said-point, we dare say that Jeonbuk, export-oriented local society, will go directly toward the Export Tower of Ivory of the 20000million dollor in the hoped-for year, 1980's, added with this, we will set our eyes on the second and third in dustrial block, width of 300 myriad pyong in Kunsan, the second its block, width of the 50 myriad in Jeonju and the same block invested 8700 million won in lrilocalty. Following this, administrative government will input the money, 80000 million won to the coastal industrial zone, the second & third block becoming a heavy chemical industry base. Viewed with this, it goes without saying that Jeonbuk industrialized development condition is will favorable, compared with the other province, as to the locational condition, for example, the low price of the land base, an unrestricted supply of the industrial water and a smooth transport means through land and sea etc, those mentioned above exactly have been proved to be true. Through the establishment of a full industrial base in 1970's, Jeonbuk Local society will be transformed into the heavy chemical industrialization from the Light Industry in 1980's.

In the cultivation of the garlic, the limitted factor was known as the soil temperature in the spring, injury Hylemyia antiqua and soil moisture. This study was carried out to find out the effect of various mulching treatment on the growth of gralic, and the influence of various mulching such as transparent plastic film, straw and black plastic films on the soil temperature, soil moisture, appearance of Hylemyia antiqua, and development of clove and yield. The mulching treatment was applied on 30th March 1977, and Susan local variety was exermined as sample. The result were summerized as follows, 1. In the early period of growth, the soil temperature was raised about 5.2℃ by double mulching (straw under, transparent vinyl top),4.6℃ by transparent vinyl, 2.7℃ by black vinyl, 1.5℃ by straw compare with control. The latter period of growth, there was no different on the soil temperature between mulching treatment. 2. Moisture content in the soil was high by the mulching treatments at dry season. In mulching, double mulching (straws under, transparent vinyl top) treatment was effective, and the order of subsequently was straw, black vinyl, double mulching (trans-parent vinyl under, straw top), transparent vinyl, control. After the rain, the straw mulching was highest moisture content and the order of subsquently, control, double mulching (straw under, transparent vinyl top), double mulching (transparent vinyl under, straw top), black vinyl, transparent vinyl. 3. Appearance of weeds was significantly decreased double mulching (straw under, trans-parent vinyl top, black vinyl, double mulching (transparent vinyl under, straw top), and straw, but transparent vinyl was signinificantly increased the weed appearance. 4. The root dry weight was increased more by mulching treatment than control, and among the treatments, double mulching (straw under, transparent vinyl top) treatment was heaviest in root dry weight. 5. For the protection of Hylemyia antiqua, the mulching treatment was effective. But straw mulching was not. The fresh weight, the diameter, and the clove weight were increased by mulching treatment, auld among the treatment, double mulching (straw under, transparent vinyl top) treatment was most effective. In the early growth stake, the growth under the transparent vinyl mulching was more effective than double mulching (straw under transparent vinyl top) treatment, but in later growth stage, double mulching (straw under, transparent vinyl top) treatment promoted the growth more than transparent vinyl mulching. 7. The bulb weight was increased by mulching treatment more than control. Among the treatment, double mulching (straw under, transparent vinyl top) treatment was most effective.

ABO_(3)형태의 Perovskite계열 복합 산화물 촉매를 사용하여 SCR공정(Selective Catalytic Reduction Process)에서 프로필렌을 환원제로 사용하여 HOx 및 SOx제거 활성을 조사하여 보았다. LaCoO_(3)촉매는 NO제거 활성이 A Site에 Ce이 40%치환되었을 때, 최고의 활성을 나타내었으며 B Site에는 60%의 Fe을 부분치환하였을 경우 저온에서의 활성향상이 있었다. 또한 전체적인 NOx제거활성 결과와 산소결함(Oxygen Vacancy)측정 결과가 선형적으로 비례함을 얻을 수 있었고, 이로 부터 Perovskite형 촉매의 반응원리를 산소결함량과 연관하여 설명할 수 있었다. In this article, ABO_(3) type Lanthanoid Perovskite catalysts have been investigated to remove NOx and SOx simultaneously in S.C.R Process(Selective Catalytic Reduction Process) using propylene as reducing agent. When the catalysts were substituted 40% of A site by Ce, it was up to the maximum activity for LaCoO_(3) catalysts. In case that B site of the catalysts were partially substituted 60% by Fe, there were improvement of the low temperature activity. Activity of these catalysts is related to the presence of Oxygen Vacancy in the catalysts. Reaction mechanism of perovskite type catalysts in S.C.R Process would be examined based on the upper results.

朴炳端,金永基,柳根宇 順天大學校 1987 論文集 Vol.6 No.1

메탄올, 에탄올, 아세토니트릴, 아세톤 및 THF의 수용성 이성분 혼합용매계어서 네가지 벤젠술폰산 벤젠치환체들의 가용매 분해 반응을 35℃에서 연구하였다. 반응속도는 비양성자성 수용성 혼합용매계에서 보다는 양성자성 수용성 혼합용매계에서 빠름을 알 수 있었으며, 이것은 양성자성 혼합용매계에 의한 친전자성 및 친핵성 보조작용이 전이상태를 안정화시키기 때문이라는 것을 알 수 있었다. 가용매분해반응 속도상수를 Grunwald-Winstein 식, 확장된Grunwald-Winstein 식 및 Hammett식으로 해석하였다. 본 반응의 결과로 부터 비양성자성 수용성 혼합용매계서 용매에 의한 친전자성 보조 작용이 크게 나타남을 알 수 있었다. Solvolysis of four benzyl benzensulfonates have been studied in aqueous methanol,ethanlo,acetonitrile,acetone and tetrahydrofuran mixtures at 35℃. The rates were faster in protic solvent-water mixtures than in aprotic solvent-water mixtures. This was considered in the light of transition state stabilization by electrophilic and nucleophilic solvent assistance of protic solvent mixtures. The rates of solvolysis are analyzed in terms of the Grunwald-Winstein equation, extended Grunwald-Winstein equation and Hammett equation. The results showed that strong electrophilic assistance of solvent is operative in the aprotic solvent-water mixtures.
