The soil-transmitted and contagious helminthes, such as Ascaris lumbricoides, whipworm, hookworm and pinworm are the commonest and the most widespread human parasites in Korea. However, the first intestinal nematode infection has been taken into account as the great endemic parasitic disease in this country. Data cited from KAPE(korean Association for Parasite Eradication) were analyzed on the bases of infection rate, fertilized ova passers/unfertilized ova passers and the evaluation of the effect of mass control on primary school-children during the past 10 years from 1969 to 1978. The results were summarized as follows: 1) The overall prevalence of Ascaris infection was decreased from 57.1% in 1969 to 22.8% in 1978 and the cumulative percent of decrease during that period was 34.3% and the mean annual decrease rate represented as 3.8%. 2) The cumulative rate of decrease in primary school children was in the range of 32.2-36.8% by school year. 3) The prevalence of Ascaris infection of primary school-children in rural area was 60% in 1969, it decreased to 17-30% in 1978, while the rates tangibly dropped to about 10% level in urban primary-school children. 4) The positive rate of A. lumbricoides in 1973 was composed of fertilized and unfertilized ova passers in the ratio of 43.l% :9.2% (F/U=4.68). Five years later in 1978 it changed to 3.22. 5) By applying the present results to the statistical model of Hayashi(1977), the theoretical infection rate per month and cure rate per treatment were computed as 2.54% and 33.3% respectively in primary-school children during the past 10 years. And the observed data were coincide with the theoretical data. From the above statistical analyses, it is distinct that the prevalence and F/U ratio remarkably decreased by efficient mass control on primary school children during the past 10 years from 1969 to 1978.

田玉蓮,金聖美 啓明大學校 生活科學硏究所 1990 科學論集 Vol.16 No.-

The purpose of this study is to grasp nutrition knowledge and lactation attitudes of mothers in lactation now and to be basic data which encourage breast-feeding in future. The subject of this study was 106 mothers of infant in lactation until 15 months old after delivery in Daegu Area (Naedang-dong,Sungdang-dong)and Dalsung Area (Hyeonpoong-myeon,Yuga-myeon, Guji-myeon.) All participating mothers of infant were randomly chosen. The time of this study was conducted from January 5th to January 25th,1988. The method of this study was that the researcher visited with mothers of infant and interviewed with them using questionaire. The collected materials were analyzed using frequency distribution,percentage,mean,X²test (Chi-Square)and F-test. The results of this study were as follows ; 1. Conducting the F-test,the score of nutritional knowledge according to age, educational level and monthly incomes showed significant differences. The score of nutritional knowledge was shown to be high among older mothers, the well-educated, city-dwellers and people with high incomes. 2. In lactation patterns according to the score of nutritional knowledge, the groups with the lower score gave their infants breast-feeding, whereas higher scoring groups provided them with bottle-feeding. 3. The sources of information about nutition knowledge and weaning did not show significant difference between division of ages and education levels. 4. In educational level and resident area of mothers, the educational level of country dwellers was low, whereas the educational level of city-dwellers was high. 5. In lactation patterns according to mothers'age, the groups who were younger than 25years old gave their infants breast-feeding, whereas the groups who were older than 30years old provided them with bottle-feeding. 6. In lactation patterns according to educational level,the groups who had lower education gave their infants breastfeeding, whereas the higher educated mothers provided them with bottle-feeding. 7. In lactation patterns according to resident area, countrydwellers gave their infants breast-feeding, whereas city-dwellers provided them bottle-feeding. 8. In lactation patterns according to monthly income,the lower income groups seemed to have breast-feeding, whereas the higher income groups seemed to have bottle-feeding. 9. The time of onset of the weaning was found to be earlier in the old aged, the higher educated and city-dweller groups. 10. The time of the termination of the weaning was found earlier in higher educated, city-dweller groups.

Hume의 「動物의 理性」에 關한 批判

千玉煥 건국대학교 1979 學術誌 Vol.23 No.1

The purpose of this thesis is a criticism on Hume's animal reason. Hume insist that an animal has thought and reason like a man. The man pursues the pleasure and avoid the pain. In this sense, the animal acts like the man. With this kind of external similarity we may analogize that the man as well as the animal have the thought and reason. It is told that the difference between the man and the animal is the reason. According to Aristotle, the man is animal rationale. And the rationalist buck as Descartes, Spinoza and Leibnitz, etc. assorted that man has innate treason. But Hume protested that theory based on the empirical position. Hume denied that the man has born with the innate reason. In recent time, Cassirer argued that the man has a symbolic ability based on the theory of Funktionskreis of Uexku‥ll. Cassirer continued to assist that the man has the feature of language with the symbol. With the language, the man bas developed the human culture. Blanshard classified four differences between the man and the animal: 1.Animal thought is tied to perception; human thought is not. 2.The cleverest of animal mind is brought to a stop by the hurdle of an abstraction; man takes the hurdle in the stride whenever he use language. 3.The animal mind cannot infer explicitly ; human minds can. 4.Human reason has added an extra dimension to the animal consciousness in the form of self-consiousness. According to the consideration as I mentioned above, I have concluded that the assumption of Hume's theory has made the fault analogy.

봉지종류 및 괘대시기가 ‘원황’ 및 ‘화산’ 배 과실의 수확기 품질에 미치는 영향

정억근,이욱용,안영직,이혁재,황용수,천종필 충남대학교 농업과학연구소 2013 농업과학연구 Vol.40 No.2

We tested fruits quality and skin coloration of two pear cultivar ‘Wonhwang’ and ‘Whasan’ produced by bagging with different kinds of paper bags in the Cheonan area, Chungnam Province, Korea. The fruits were bagged at 35, 45, 55 or 65 days after full bloom (DAFB) with 3 kinds of double layer paper bag which consisted of grey color, yellow color and newspaper for outer layer. The great extent of light interruption was observed in grey colored outer paperbag among three kinds of paperbag which showed only 0.46% of lowest light transmittance when compared with 43.7% and 40.0% of yellow paper and newspaper, respectively. The development of skin redness (a*) increased with the delay of bagging time in two pear cultivars. But the fruits treated at 65 DAFB showed uneven coloration and excessive development of redness which represented low fruit external appearance value. Uniform flesh firmness was attained at the fruits bagged with grey outer color paperbag regardless of bagging time, although the fruit quality indices including soluble solids and titratable acidity did not change significantly by using different kind of fruit bags and bagging time in two pear cultivar. Based on our results, it was explained that the grey-colored fruit bag had positive effect on the development of skin coloration without any detrimental effect on fruit quality factors in ‘Wonhwang’ and ‘Whasan’ pears.

우리나라와 일본의 중학교 가정과 교육과정의 비교연구

정옥님,김영숙,전옥하 조선대학교 교육연구소 1986 교과교육연구 Vol.9 No.-

Every country in the world has unique curriculums. This is because the expectation of individuals differs with each country's situation, social environment and social needs. Since our country is no exception, in legal limitation the educational curriculum is organized and restricted directly by the goverment. That is, the educational curriculum is organized to embody the national educational ideals. In this respect it is possible to explain the organization of the educational curriculum with respect to the socio-cultural background. The content of educational curriculums, receiving social influence, is determined in the of viewpoint sociology of knowledge through social analysis of the ideological and cultural background and organization process for the selection of content. From this point of view the middle school home economics curricums in Korea and Japan have been comparatively analyzed. Viewing the educational curriculum as being related to political ideology, national political ideology is to build an ideal society with the aid of educational activities to cultivate the ideal individual. In order to do this, political ideology is taken into account in the selection of content that is realizable as having political pursuable value by applying tactical and systematic restrictions on the educational curriculum. The organization of Korean and Japanese educational curriculums are formed in this context. Therefore, the educational ideals, educational laws, and educational objectives have been compared and their relationships surveyed. As a result, it has been found that the educational curriculum has been organized with the purpose of individual happiness and citizenship in Japan and individual character-building and social development in Korea. It has also been found that the objective of home economics education in Korea is a search of one's role and direction in society, and in Japan emphasis is placed on individual personality development and social adjustment. It can be said that this comes from the differences in the socio-cultural environments that the two countries have. So far the Korean educational curriculum has been revised four times and problems have always arisen in the adaptability of the curriculum. But, because our educational curriculum is formed under policy and systematic restrictions, before evaluating adaptability it is more desirable to reflect on the necessary content in preparation for life in society in order to meet changes and the future by finding adaptability in our present situation.

종양형성에서의 Ku단백질의 역할

조병옥,박춘매,장인엽 朝鮮大學校 附設 醫學硏究所 2007 The Medical Journal of Chosun University Vol.32 No.2

Ku is a protein which act as a repairing enzyme for the DNA double strand breaks (DSBs). It has a heterodimeric structure composed of two subunits, Ku70 and Ku86. The detail mechanism of Ku in DNA repair processes is still not unknown, but it is certain that Ku is a one of key protein in maintenance of chromosomal integrity and cell survival. Recent studies reported that dysfunction of Ku protein is related to the development of radioresistance in case of overexpression of Ku and tumorigenesis with Ku underexpression. As Ku may act as either a tumor suppressor or an oncoprotein, precise regulation of Ku function may be important for the tumor suppression. Ku may be used for the treatment of cancer to resist radiotherapy or chemotherapy.

崔應鈺,金泰淵,丁銓殷 고려대학교 의과대학 1989 고려대 의대 잡지 Vol.26 No.1

PYROST® is a biocompatible porous matrix implantable as a bone graft substitute. This biomaterial has been used in a variety of experimental settings over the past years and more recently has been used in clinical applications for the filling of bone defects. Its use in human may help to eleminate the morbidity of autogenous bone graft donor sites and resorption of autogenous bone graft. We studied the new bone regeneration within a PYROST® block which were placed end to end in a subperiosteal pocket on the nasal dorsum of 1.8-2.0 ㎏ New Zealand white rabbit. En block specimen were harvested at 4, 8 and 12 weeks post onlay. These were then decalclfied, imbedded and sectioned in the sagittal plane. For the confirmation of bone regeneration within a PYROST® we used weighing the PYROST and light microscope. point-counting technique and fluorescent microscope. The results obtained were summarized as follow: 1. There was no volume change of PYROST® 2. The activation of osteoblasts and bone matrix were found at 4 weeks and matrix of lamellar pattern was found 12 weeks post onlay. 3. The quantity of the regenerated new bone within a PYROST® was increased at 12 weeks(3.2±2.1%) than 4 weeks(1.5± 1.8%).

全泰玉,朴春根 동아대학교 환경문제연구소 1981 硏究報告 Vol.5 No.1

This study has analyzed examined an experiment on the frictional wear of tool materials at high speed. The results of experiment are as follows. 1. With the increase in the frictional velocity and the contact pressure, the decrease of the frictional coefficient is influenced more by the softness of the frictional surface layer than by oxide. 2. Specific wear rate is influenced more by the frictional velocity than by the contact pressure. 3. The character of the specific wear rate and the contact pressure of each test piece is similar to one another.
