The aim of this study is to examine the physical conditions of 40 runners newly selected by Korean Amature Athletic Association, to find out their capabilities for their future performances in their respective field, and to present some suggestions for training them hereafter. The items examined for this study are height, weight, the length of leg, the strength of legs, the strength of back, the flexibility, the ability for repetition of motions, the reaction time, the runner's maximum oxygen consumption and debt and his metabolism in rest. The results of this study are as follows: 1. In the male runners of the 25 selected champions, the 13 year-age group had excellent physical characters, but the other age groups were low in both physical characters and muscular functions. Among the female runners, the 12 and 14 year-age groups good physical characters and 15, 16 and 17 year-age groups showed good muscular functions. 2. No. 15 champion was found having promising conditions for a long-distance runner. His maximum consumption oxygen was 4.2 liters. 3. No. 16 champion was found more suitable for an intermediate distance runner than for a long-distance runner. His maximum oxygen debt was 15.33 liters. 4. No. 34 champion had excellent muscular functions and other good conditions for a short-distance runner. 5. No. 36 champion was most suitable for a 400 meters runner. Her maximum oxygen debt was 5.765 liters. 6. No distinguished physical fitness for a runner was found among the other champions at present. 7. In measuring the maximum oxygen consumption and maximum oxygen debt, the degree and time for loading were not enough for the cases of the most runners and especially in the case of the female runners the time of loading was too short.

OOP언어의 Cast 방법에 관한 연구

윤성일,남숭환,이봉하 공주영상정보대학 2002 논문집 Vol.9 No.-

OOP 언어인 Java, C++는 대표적인 객체지향 언어로서 널리 사용되고 있다. 이들 언어의 특징은 c1ass를 이용하며 다양한 cast방법에 의한 효율적인 프로그래밍 작성이 용이하다는 것을 볼 수 있다. 본 연구에서는 cast의 효율적인 설계방법과 작성기법들에 대하여 연구하였다. 클래스를 이용하여 모듈을 세분화 조립하는 경우 프로그램 성능향상에 현저히 드러난다. 또한 프로그램활용 목적에 따라 유용성, 이식성, 확장성 등을 고려하여 시스템을 디자인하는 것이 중요하다는 것이다. 쉬운 조작으로 많은 효과를 이를 수 있는 것이 COP언어의 특징이다. OOP 언어는 또한 컴파일 시간과 실행시간에 리턴하는 값이 다른 경우 프로그램에 치명적인 영향을 미치기 때문에 class를 이용한 casting 방법을 이용하는데 상당한 주의가 요구되는 것을 위의 예로 보았다. 이로서 향후 연구과제는 실행시간 리턴 값, 오브젝트 참조 값, 메모리의 효율적 사용방법을 위해 새로운 cast 연산자들인 const_cast, dynamic_cast, reinterpret_cast, static_cast의 효율적인 기능을 분석하는데 있다.

조선시대 충청권에 발생한 황충(蝗蟲)에 대한 문화곤충학

윤일,문태영,남상호 대전대학교 기초과학연구소 2002 自然科學 Vol.13 No.1

조선왕조실록을 통하여 황충(蝗蟲) 즉 풀무치로 추정되는 메뚜기의 대발생이 충청권에서는 어떤 양상으로 발생하였는가를 추적하였다. 충청권에서 대발생한 메뚜기는 다양한 형태로 기록되고 있으며, 충청북도보다 충청남도에서 더 많은 대발생이 기록되었다. 그런 원인으로는 충남에 경작지가 많아서일 것으로 추측되며, 경작지는 조선시대의 농경정책이 도작을 적극 권장함에 따라 삼국시대에 대발생하던 산지와 초지의 경계역에서 발생하는 풀무치와는 다른 메뚜기종도 포함될 가능성을 검토하였다. 또 대발생 경향도 우리나라에서는 오랫동안 높은 기온이나 습도 유지가 어려우므로 세대반복에 의한 폭발적인 개체수 증가에 의한 대발생 보다는 동시발생에 의한 밀도의 증가에 따른 군거성향 증가의 가능성을 제시하였다. It was assumed that the outbreaking locusts recorded during the Chosun dynasty were most likely to be Locustu migratorla migrutoriu and its impact on the Chungchung provinces were discussed in entomology and ecology based on historical records. The outbreaking patterns were recorded in various ways. The locusts were more frequently and widely recorded in the southern part than in the northern part of Chungchung provinces. It may be due to the fact that cultivation fields were more in the southern part. It is also suggested here the change of the outbreaking species because the political preference in agriculture encouraged to cultivate rice in Chosun dynasty while not so in ancient three kingdoms a s Shilla. Baekje and Kokuqe. The outbreaking types were also diagnosed. Because of the temperate climatic geography, it is difficult to maintain high temperature and humidity in a considerable period enough to allow locusts repeating their generations in Korea. Therefore, it may be reasonable to incline to the simultaneous hatching leading to high densty of locusts and then eventually to outbreaking .

國産高張力鋼의 熔接部의 機械的 性質에 關한 硏究

南勝義,金聖培,金錫胤 弘益大學校 1982 弘大論叢 Vol.14 No.2

A study has been performed on the mechanical properties and the micro-structure of the welded zone in the high tensile steel produced in Korea. The experimental results indicated that the tensile strength and the hardness were increased in welded zone. The micro-structure of the welded zone was finer than that of the base metal. It may be considered that the increase of the mechanical properties is due to the chemical composition of electrode being different from the base metal and to the structure getting finer through the course of solidification.

연구배경:인슐린저항성은 제2형 당뇨병과 심혈관질환의 주요한 위험 인자로 성호르몬과 상호 관계가 있다고 알려져 있다. 그러나 여성과는 달리 남성에서는 연령과 인슐린저항성에 따른 유리 테스토스테론과 성호르몬 결합 글로블린 농도의 변화에 대한 연구가 부족한 실정이다. 그러므로, 본 저자등은 제2형 당뇨병 남성 환자에서 정산인과 비교해서 유리 테스토스테론과 성호르몬 결합 글로블린 농도를 측정하고 연령에 따른 변화 정도를 알아보고자 하였다. 방법:대상 환자 모두에서 연령과 체질량지수, 총 콜레스테롤, 중성지방, 공복혈당과 인슐린 농도를 측정하였다. 혈중 유리 테스토스테론 농도는 방사면역측정법(radioimmunoassay)을 이용해서 측정하였고, 혈중 성호르몬 결합글로불린은 면역방사계측측정법(immunoradiometric assay)을 이용해서 측정하였다(Diagnostic System Laoratories, Wbster, TX, USA). 결과:1)제2형 당뇨병 남성 환자에서 정상 대조군 남성에 비해 성호르몬 결합글로불린은 104.1±35.0 vs 25.7±3.5 mole×10??로 의미 있게 높았으나(p<0.001), 유리 테스토스테론은 13.7±9.5 vs 13.6±6.5 ng/dL로 차이가 없었다. 2)연령과 성호르몬 결합 글로블린 사이의 상관 계수는 제2형 당뇨병 남성 환자에서 0.40로 중등고의 양의 상관 관계를 보였고(p<0.001), 정상 대조군 남성에서 0.11로 유의한 상관 관계를 보이지 않았다. 연령과 유리 테스토스테론 사이의 상관 계수는 제2형 당뇨병 남성 환자에서 0.08, 정상 대조군 남성에서-0.17로 모두에서 유의한 상관 관계를 보이지 않았다. 3)연령과 체질량지수를 보정한 후에 제2형 당뇨병 남성 환자와 정상 대조군 남성에서 혈중 인슐린 농도, 유리 테스토스테론과 성호르몬 결합 글로블린 사이에는 상관 관계가 없었다. 결론:제2형 당뇨병 남성 환자에서 정상 남성에 비해 성호르몬 결합 글로블린 농도가 증가되어 있었으며, 유리 테스토스테론은 차이가 없었다. 연령이 증가함에 따라 성호르몬 결합 글로블린이 제2형 당뇨병 남성 환자에서 정상 남성에 비해 증가 폭이 의미있게 컸으며, 유리 테스토스테론은 변화가 없었다. Background: Insulin resistance is a risk factor for cardiovascular disease and type 2 diabetes mellitus. There are many previous studies indicating that insulin lowers serum sex hormone-binding globulin levels, and there is inverse correlation between insulin resistance and serum sex hormone-binding globulin levels in women. However, in men, a limited number of studies are available to explain the effect of sex hormone on age and insulin. Therefore, the present study was undertaken to investigate the relationship among free testosterone, hormone-binding globulin and age in type 2 diabetic men and control subjects. Method: Age, body mass index, total cholesterol, triglyceride, fasting blood sugar, and insulin concentrations were examined on 89 type 2 diabetic men and 47 control subjects. The free testosterone level was measured by commercially available double-antibody system (Radioimmunoassay). The sex hormone-binding globulin level was also measured by commercially available double-antibody system(Immunoradiometric assay). Results: 1) Sex hormone-binding globulin level was significantly increased in patients with type 2 diabetes. However, there was no significantly difference in free testosterone level between the two groups. 2) Sex hormone-binding globulin was positively correlated with age (r=0.4, p <0.001) in patients with type 2 diabetes. Sex hormone-binding globulin and free testosterone were not correlated with age in control sujects. 3) Free testosterone and sex hormone-binding globulin concentrations were not significantly related to serum insulin concentration after adjusting for age and body mass index. Conclusions: We observed increased sex hormone-binding globulin concentration in diabetes man, and was a positively related to age. Further studies are needed to understand the relationships between age, insulin resistance, testosterone, and sex hormone-binding globulin concentrations(J Kor Diabetes Asso 24:699~707,2000).

비만의 예방과 치료에 관한 연구

윤상화,백남섭 龍仁大學校 體育科學硏究所 1995 體育科學硏究論叢 Vol.5 No.1

As our result shows, a fatness comes from eating too much and is fundamentally owing to lack of exercises. (Pyung Woo Lee, 1990). Thus, scholars and practitioners recommend a diet and exercises. Since lack of exercises causes a fatness, a fatness can be prevented and cured by proper exercises. However one should be cautious in choosing and practicing a specific exercise. Inattentive exercise will not be effective and sometimes harms the knee joint and ankle. Several studies including Lee(1990) and Shin(1992) have shown that one should practice a relatively moderate exercise for a long time. A dietary treatment is also essential for the fatness. One should try to have a proper dietary habit from an early pfase of one's life. Finally one's effort to preyent and cure a fatness should de accompanied by his neighbors including peers and family.

남해선,황규윤,,백병준,정윤영,오천환,조성란,박준수 순천향의학연구소;Soonchunhyang Medical Research Institute 2000 Journal of Soonchunhyang Medical Science Vol.6 No.1

To evaluate usefulness of application of MAST-CLA to indetify allergens, authors conducted MAST-CLA allergen-specific IgE assay and collected allergy related symptoms in 118 allergic patients diagnosed at Soonchunhyang University Chunan Hospital during October 1998 through January 2000. The results were as followings; 1. The mean (SD) age was 23.1 (±12.17) years old and teenagers accounted for 33.1% of patients. 2. The frequent allergic symptoms were sneezing (59.3%), rhinorrhea (53.4%), nasal stiffness (44.1%), itching sensation (24.6%), cough or sputum (16.1%), and eye symptom (8.5%) in order. 3. Among these subjects, 62.7% of patients revealed at least more than one specific allergen and 70.3% showed elevated total IgE levels by MAST-CLA. The three most frequent specific allergens were Dermatophagoides farinae (47.5%), Dermatophagoides pteronyssinus (45.8%), and house dust (30.5%). 4. While age was not significantly related to positive of both specific allergens and total IgE (P>0.05), sneezing and nasal stiffness were significantly associated with positive of specific allergen and total IgE, respectively (both P<0.05). 5. Total IgE increased with the number of specific allergens, but both specific allergen and total IgE were not significantly related to increases of allergic symptoms (P>0.05). In conclusion, our data suggest that MAST-CLA allergen-specific IgE assay is useful measure for identification of causative allergens in allergic patients, however, it is recommended that more specific allergic antigens should be determined and replaced or added to Korean inhalent panel of MAST-CLA.

전기영동에 의한 동양란(Cymbidium spp.)의 단백질 유형비교

윤경은,홍성숙,이남희 서울여자대학교 자연과학연구소 1991 자연과학연구논문집 Vol.2 No.-

본실험은 전기영동을 이용하여 단백질과 동위효소의 유형을 비교 분석함으로 종과 품종을 구분할 수 있는가의 가능성을 조사하고 전기영동에 적합한 난의 부위와 효소의 종류를 선정코자 실시하였다. 1. 한국춘란은 부위별로 꽃봉오리, 뿌리끝, 어린잎, 성엽을 6% polyacrylamide slab gel로 단백질을 비교한 결과 부위별로 유형을 달리하였으나 band의 분리가 명확하지 않았다. 2. 10% SDS polyacrylamide slab gel에서는 band의 분리가 명확하였고 영동재료로는 어느 때나 쉽게 채취가 가능한 잎이나 뿌리를 사용하는 것이 편리하나 뿌리는 phenol 함량은 적으나 단백질 함량이 극히 낮으므로 잎을 시료로 쓰는 것이 양호한 편이었다. 3. 잎을 시료로 쓰는 경우는 엽록소, phenol의 제거가 필요하나 배양중인 rhizome을 사용하면 이러한 난점이 없이 단백질 유형이 뚜렷이 나타나, 춘란(Cymbidium goeingii), 한란(C, kanran), 죽백란(C, lancifolium)을 구분할 수 있었다. 4. Rhyzome의 esterase, peroxidase, acid phosphatase, glucose phosphate isomerase의 동위효소를 비교한 결과 단백질 유형으로는 분류가 어려웠던 춘란(Cymbidium goeringii)과 춘란복륜(Cymbidium goeringii:variated leaves)도 구분할 수 있었다. Peroxidase는 band는 여러가지로 나타났으나 esterase와 같이 band pattern이 명확지 못하였고 acid phosphatase와 glucose phosphate isomerase는 한개씩의 band만이 나타나 분류에는 적합하지 않은 효소로 생각되어졌다. The buffer soluble proteins were extracted from flower, root, young leaves, old leaves, and cultured rhizome. Different patterns of general protein were observed among the tested organs. Among the samples rhizome were the most suitable for electrophoresis to differentiate cultivars. Band patterns of general protein, esterase, peroxidase showed typical band patterns among Cymbidium goeringii, Cymbidium kanran, and Cymbidium lancifolium which have similar appearance of vegetative leaves. The isozymes of esterase, peroxidase, acid phosphatase, and glucose phosphate isomerase in cultured rhizome were analized. The well-resolved zones of esterase activity were detected. The differentiation of Cymbidium goeringii and Cymbidium goeringii : variated leaves which was hard to differentiated by general protein patterns, could be done by esterase isozyme band pattern.
