The purpose of this study is to understand how the unit objectives and contents associated with environment are reflected on the 6 kinds of chemistry- I textbooks in the 7th curriculum and to present how to deal with the environmental education in chemistry- I. The results of this study are as follows. First, units associated with environment account for an average of 43.7% on chemistry- I in 7th curriculum. Second, contents of units related to environmental education on chemistry- I in 7th curriculum are environmental pollution(17.8%), environmental preservation and environmental pollution prevention(15.9%), environmental hygiene(12.2%), and any other things, Environmental pollution takes up a considerable part of environmental education. Third, the results for analyzing the objectives of chemistry- I in 7th curriculum show that Information Knowledge Awareness(34.0%) and Skill (29.9%) take up most parts. Fourth, Orientation (I) as analysis standard for objective of the units related to environmental education accounts for 10.2% of the total. It is clear that environmental education is carried out from STS point of view. In conclusion, environmental education in Chemistry- I focuses on fostering students' ability to apply the fundamental notion of chemistry to real life associated with environments. Therefore, it is necessary that environmental education in Chemistry- I should include value, attitude and participation and that improve students' ability to approach the environmental problem comprehensively.

Jeongrimsaji as temple remains of Baekje Sabi period, its re-excavation has been carried three times in full scale. As a result, the buildings in left and right of lecture hall was largely identified in 3 forms. First, layout of small buildings in left and right of lecture hall. Second, layput of corridor in left and right of lecture hall. Third, layout of construction site in the north of corridor in left and right of lecture hall. Above second is included into remains of Gorye, the third is included into remains of Baekje - the remains were almost ruined then. The first form and third form in above is different each other in size of buildings, form of layout, and location. It is important to investigate these points: the time of constructing the buildings; what position have the use and function of the buildings in the temple? ; transition process of layout of the Buddhist temple. In this context, of temple remains in Baekje during the 5~7th century, the cases where construction sites in left and right of lecture hall and construction site in the north of corridor are identified, have been reviewed. Based on this review, the use and function of buildings, their transition process were investigated. The survey results show that small buildings in left and right of lecture hall existed in the middle and later period of the 6th century. During the later 6th century ~ the 7th century, construction site in narrow and long square shape was located in left and right of lecture hall instead of small buildings in the north of corridor. Therefore, it is identified that the aforementioned thing is earlier stage and the latter thing is later stage.

토끼의 족서부 피하로 Bovine Gamma Globulin과 Ineomplete Freud's Adjuvant를 주입한 후 국소임파절내의 항체생산 세포인 형질세포의 rER을 경시적으로 관찰한 결과를 요약하면 다음과 같다. (1) 항원투여전의 형질세포의 rER 는 일반적으로 편평낭상 (flattened sac) 을 정하고, 항원 투여 후 3 일째에는 일반적으로 소포상 (vesic lar) 를 그리고 7 일내지 10 일째에는 공포상 (vacuolar) 를 정하고 그 강내에는 intracisternal granule 이 다수 출현하며 20 일째에는 다시 확장낭상 내지는 편평낭상을 정하게 된다. 이상의 연구성적으로 보아 편평낭상을 정하는 형질세포의 rER에 항원성 자극을 가하면 처음에는 소포상으로 되었다가 공포상으로 변화하며, 항원 성자극이 소퇴하면 다시 편평낭상으로 복귀된다고 생각된다.

Purpose: The purpose of this study was to develop an instrument to measure breastfeeding empowerment for the Korean mother, and to test the validity and reliability of the instrument. Method: The items of instruments used was based on literature review. Nineteen item scales were developed with five domains. In order to test reliability and validity of the scale, data was collected from 99 mothers who were within 4weeks, postpatum and 88 mothers who had had children within 1 year. Data was collected between September 2nd and 24th by a self-reported questionnaire. Result: The results were as follows: As a result of factor analysis three times, 19 items were selected from the total of 24 items. Five factors evolved by factor analysis, which explained 65.7% of the total variance. The first factor 'breastfeeding skill' explained 34.1%, the 2nd factor 'group empowerment' 10.6%, the 3rd factor 'breastfeeding will' explained 7.8%, the 4th factor 'social policy empowerment' 7.0%, and the 5th factor 'adherence to exclusive breastfeeding' 6.2%. Cronbach's alpha coefficient of this scale was .8781. Conclusion: The study supports the reliability and validity of the scale. Because the main concept of breastfeeding empowerment was breastfeeding skill, there were distinct differences in the dimensions of breastfeeding empowerment scales.

Female genital morphology of Cryptocercus Kyebangensis is described, focusing on the structural features of ovipositors at each developmental stage. Ovipositor valves were the first genital structures to appear in female nymphs. The caudal margin of the 9th sternum was nearly straight in the 1st instars of both sexes, with a slight median notch, but was deeply concave in the female nymphs of the End instar. The 1st valve of ovipositor budded off from membranous fold between the 8th 8nd 9th sternum and a pair of the 2nd valve came from the 9th sternum. Separation of styli occurred in the female nymphs of the 8th or 9th instar. Some parts of the female genitalia were sclerotized after the final molt. Spermathecae were the fork type and leaned a little to the right in the middle line of the genital chamber from ventro-posterior view. The trace sealed with sclerite materials existed on the spermathecal opening. The genital segments (segments Ⅷ, IX, and X) were concealed completely by the 7th tergum and sternum posteriorly expanded. Terminal lobes which exist in the Blattidae were not observed in C. Kyebangensis. Instead, the apicolateral emargination existed on the terminal abdominal segment of C. Kyebangensis females.

To investigate the etiology, pathogenicity and virological properties of NYJ-1-87 strain of Aujeszky's disease virus (ADV) that was isolated from the diseased piglet in Korea, the virus at $10^{6.0}TCID_{50}/0.1ml$ was inoculated intranasally and subcutaneously into 30 to 35 days-old piglets. Results obtained through the experiments were summarized as follows. 1. Ten of the infected piglets were clinically observed for 15 days. On the 2nd day post-inoculation(pi), the signs of pyrexia, anorexia and convulsion were noted. On the 4th to 7th days pi, nervous signs of incoordination and intermittent spasm were shown in the most of piglets, and one out of 5 piglets infected intranasally was died with severe nervous signs at the 7th day pi. The signs became relieved on the 8th day pi and all of remainder were completely recovered on the 13th to 14th days pi. 2. In hematological study, prominent decrease in the number of total leukocyte and lymphocyte was shown in the ADV-infected piglets on the 6th day pi. On the 8th day pi, the cell numbers were slightly increased and returned to normal level on the 10th day pi. 3. Viral excretion of the ADV-inoculated piglets was examined by swabbing of nasal and oral cavities, and rectal feces. During the periods of the 3rd to 11th days pi, the virus was excreted intermittently from nasal and oral cavities, and rectal feces. The nasal excretions were shown the highest virus concentration of $10^{5.2}TCID_{50}/0.1ml$ at the 5th day pi. 4. Recovery of the inoculated virus from various organs of the piglets that were died or experimentally slaughtered was attempted, and the virus was isolated from the tissues of brain and tonsil by the cultured cell-inoculation method. The highest recovery rate was noted in the tonsil. By indirect immunofluorescence antibody assay using ADV-monoclonal antibody, the viral antigens were detected in tissues of spleen and liver as well as brain and tonsil on the 7th to 9th days pi. The virus was not isolated from blood and the tissues of lung and kidney throughout the experiments. 5. Titers of virus neutralizing antibody in the piglets experimentally infected with ADV became increased after the 6th to 9th days pi in both of intranasal and subcutaneous inoculation showing the highest titers of 64 to 128 on the 29th day pi. When the antibody levels were measured by radial immunodiffusion enzyme assay, the reactive diameter was enlarged to be positive after the 4th to 6th days pi in both of intranasal and subcutaneous inoculation showing the largest diameter of 13 to 14mm on the 29th day pi.
