A five years old female Shih-tzu was referred to the veterinary medical teaching hospital at Chungnam national university with soft bloody diarrhea and tenesmus. On rectal palpation, solid mass was palpated in colorectal region. In radiographs, small intestine was deviated cranially, descending colon and rectal junction were deviated caudoventrally in lateral projection of the abdomen. In ultrasonographs, hypoechoic nodulation of mesenteric lymph node in colorectal junction, mixed echoic thickening of colorectal wall and irregular margination were observed. Rectal endoscopy revealed that colorectal men was partially obstructed due to compression of the mass. Also, severe ulceration, inflammation and hemorrhage were also observed in descending colon. The mass was resected through the laparotomy. In histopathology, it was diagnosis of lymphoma in the colorectal junction.

9종류의 어란에서 지방산을 추출하여 GC-MS로 분석한 결과 다음과 같은 결과를 얻었다. 1. 어란중 지방산을 GC와 GC-MS로 분석할 때 초기온도를 60°C로 하고 승온률을 9°C/min, 마지막 온도를 220°C로 하는 승온법이 목적 성분을 분리하는데 가장 좋은 결과를 얻었다. 2. 가자미, 날치, 대구, 명란, 농어, 성어, 오징어, 참치, 청어의 알에서 지방산을 추출하여 GC로 분석한 결과 포화 지방산은 myristic acid, palmitic acid, stearic acid, arachidic acid가 검출 되었고, 불포화 지방산은 oleic acid, linolenic acid 가 각각 확인 되었다. 3. 포화 지방산은 myristic acid가 명태알에 11.8㎍/g 으로 가장 많이 함유되어 있었고, palmitic acid는 오징어알에서 106.32㎍/g으로 가장 많이 함유되어 있었다. Stearic acid는 농어알에 53.03㎍/g, arachidic acid는 대구알에 8.5㎍/g으로 가장 많은 양이 함유되어 있었다. 4. 불포화 지방산인 oleic acid와 linolenic acid의 함량을 분석한 결과 oleic acid는 가자미 알에 linolenic acid는 명태알에 각각 109.12㎍/g, 62.48㎍/g으로 가장 많은 양이 함유되어 있었다. Fatty acids were extracted from the roe of flounder, flying fish, Pacific cod, Alaska Pollack, mero, shark, squid, tuna, and herring. They were methylated and analyzed by GC and GC-MS. Most of fatty acids found from 9 different roe were myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, and linolenic acid. The roe of Alaska Pollack, squid, mero, and Pacific cod contained 11.8ug/g, 62.48 ug/g, of unsaturated fatty acids such as oleic acid and linolenic acid, respectively. The roe of flounder and shark had higher content unsaturated fatty acids than rest of the roe. The roe of Pacific cod, Alaska Pollack, mero, squid, tuna, and herring had larger amount of saturated fatty acids than the rest of the roe.

Epichlorohydrin Polymer의 배합에 의한 성능변화 및 그 응용에 관한 연구

李明煥 서울여자대학교 1978 서울여자대학논문집 Vol.- No.7

The purpose of this study is to establish an effective way to utilize the application of Epichlorohydrin polymer compound. The results are shown as follow: 1. For the most effective heat-resisting compound of epichlorohydrin hose and tube either red lead or Dyphos/Dythal family is recommended to be used as acid acceptor, either NBC and Niclate as fire-fighting aid, and ethylene thiourea (NA-22, Thiate N or Pennac CRA) for crosslinking. Imidazol too appears to be the most effective for air aging, and especially the vulcanizer made under sufficient curing time turns out to have excellent heat-resisting effect. For the coulping agent Silane-189 was used, and when silica was charged in, long-range heat-proof quality was far better than that when in black compounding . 2. In long-range heat-proof air aging effect heat-resisting epichloro hydrin polymer compund was superior to CR, CSM or NBR, but in air aging effect was a little inferior heat-proof EPDM. In the meantime, epichlorohydrin only polymer compound shows a higher numerical value in long-range aging test than EPDM. The compound which showed the highest antioxidizing effect was ACM/ECO blend.

In order to develop an appropriate health care service program for a population. it is of utmost importance that the particular population's demograhic and socio-economic characteristics are taken into consideration. The purpose of this research was to determine which of the demographic and socio-economic factors gathered from basic family health records contribute to the decision by people to use either the hospitals and clinics. or health centers for their children's health care. The target area of this study was Guro 6 dong. Guro-Ku, Seoul. A sampling method of choosing families whose children(1-3 years old) had already received their third DPT vaccination resulted in 405 subject familes out of 3904 family health records which were on file at the Guro 6 dong health subcenter A general survey of the households under study revealed that 61.9% of the children received the vaccinations at a health center. and 38.1%. at a clinic or a hospital. The demographic. socio-economic. and maternal health behaviour characteristics were all analyzed for each of the 405 families. In addition. the likelihood of each family to use either the clinic and hospital or the health center was analyzed. Significant differences in the data were determined by the Chi-squared methcd. The factors affecting the utilization of medical facilities ware examined through a stepwise discriminant analysis. using the type of medical facility utilized as group variable, and the demographic characterlistics socio-economic characteristics. or maternal health behaviour as discriminant variable. 1. Of the demographic characteristics. father's education. the mother's age. mothor'education. and the mother's occupation had a hit ratio of 58.0% 2. Upon the analysis of socio-economic characteristics, type of housing, status of ownership of the house, household income, and whether the family had a telephone had a hit ratio of 69.9%. 3. Using maternal health behaviour. as the discriminating variable, and prenatal care, postpartum care had a hit ratio of 70.9%. 4. The stepwise discriminant analysis resulted in postpartum care, type of housing, ownership status of the house, mother's occupation, monthly income, and ownership of telephone having a hit ratio of 73.4%. The collection of basic health information of a population is essential for planning an appropriate health care service program. This research has shown that, as part of the basic information, demographic, and scoio-economic, as well as maternal health behavior characterisics are very important in determinizing an individual's preference for a particular type of medical facility from the available ones. Furthermore, these specific characteristics of a population may be used in planning a comprehensive health care service program to make certain appropriate facilities and programs are available. More need to be done in the future to discover the factors which influence the effective utilization of health service programs available to the population.

名詞化의 語彙的 接近

In the process of nominalization we come into the problem whether nominals are derived transformationally or lexically. Transformationalists depend largely on a great deal of descriptive complexity in order to derive nominals, Therefore language learners should deal with large numbers of related transformations to do it. On the other hand, according to the lexicalist hypothesis language learners have only to learn the differences in the deep structure. Chomsky (1970) says the extension of a lexicon enables the categorial component to be simplified. The difference between the lexicalist and the transformationalist in approaching to nominalization lies in the method of derivation With the properties lying in the base structure lexicalists extend them, establishing D-structure close to S-structure to simplify the transformational component, relating it to the transformation, joining the semantic representation to D-structure through categorial components. The appliation of X-convention to the derivation of nominalization enables the lexicalists to derive nominals directly without violating the basic lexicon. But of-insertion by adjunction satisfies CRP in S-structure, violating the projection principle, which shows N?=P? proving to be contradictory. Among the three solutions suggested by Chomsky(1981) and Stowell(1981), we consider Chomsk's explanation. (45) c, in which a neutralized category charing properties of NP-PP is proposed, is most proper.

Pyrolytic analysis based on pyrolysis-gas chromatography(PGC) technique have been performaed for identification of NR, BR, SBR, CR, EPDM and their blends. The results each of characteristic peak of single rubber showed dipentene, 4-vinylcyclohexene, styrene, chloroprene, 2,4-dimethy1-1-heptene. Since the physicochemical properties of blends of NR/EPDM. BR/EPDM, SBR/EPEM, CR/EPDM,NR/EPDM, BR/SBR/EPDM were heavily affected by their blending ratio, it was found to be essential to confirm the blending ratio of the blends. Finally, the standard calibration curves for characterization of various blending ratio in each system were obtained on the basis of their pyrograms.

Apple wine was prepared by using apple juice which was inoculated with Saccharomyces cerevisiae and Kluyveromyces Lactis. Those chimical compositions such as alcohols and organic acids were determined with gas chromatographyt to investigate the variation of its content by the fermentation. Alcohols such as methyl, n-propyl, I-amyl alcohols were found in the most apple wine. Alcohol contents in teh groups SCⅢ and KLⅢ were slightly higher than SCⅡ KLⅠ group. Lactic acid and succinic acid were concentrated and organic acids such as malonic, succinic, maleic, tartaric acids were also detected in the most samples. The acid contents were increased whereas the pH were decreased as the duration of fermentation was prolonged. The value of pH was lowest in the SCⅡ group and was reduced in the order of SCⅠ, KLⅢ, KLⅠ, KLⅡ and SCⅠ group. The total acid content was highest in SCⅡ. The total acidities and pH values were showed almost the similar changing pattern. The metal contents were increased as the fermentation time was prolonged. The contents of Ca and K which were transferred from the raw material were found to be 52.74-95.36, and 139.49-169.58 ppm, respectively.
