During compaction and sintering premixed Al-Cu powders, the effects of green density, sintering temperature and sintering time on dimensional change and hardness in sintered specimens were discussed and the phenomena of all conditions during age hardening were examined. The specimens were sintered in nitrogen atmosphere at temperatures ranging from 560℃ to 620℃ for 10, 20, 30 and 60 minutes. The dimensional changes of specimens during sintering are occurred in no time as the sintering temperature increased, and the expansion is occurred largely as the green density increased. The magnitude of peak hardness to age hardening is similar to wrought parts.

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.

중산간 농업용 만운저수지의 수질환경특성

남귀숙,장정렬,이광식,윤경섭,이상준 한국환경농학회 2003 한국환경농학회지 Vol.22 No.1

농촌지역의 도시화와 산업화에 따라 농촌 수질환경의 오염이 심화되고 있다. 경북 안동의 중산간지대에 위치한 만운저수지는 유역면적 23.8 km², 수표면적 0.4 km², 저수량 2.0×10^(6)m³의 부영양화 된 중규모 농업용저수지로서 1999년 수질환경특성조사를 실시하여 오염된 유사 농업용 저수지의 수질특성이해에 중요한 자료로 활용하고자 하였다. 만운저수지의 수질에 영향을 미치는 유역면적값(DA)/호수면적값(SA)의 비가 56.1로 국내 다른 농업용 저수지보다 높게 나타나 유역의 오염물질 부하가 높은 편이며, 평균 수심과 관련된 유효저수량(ST, m³)/수표면적(SA, m²) 비는 4.79로서 안동호, 팔당호보다 낮고 삽교담수호 등과 비슷한 값을 보여주어 부영양화의 잠재성이 높은 것으로 나타났다. 만운저수지의 수질조사결과 COD는 11.1 mg/L, 총질소 1.426 mg/L로 환경기준중 생활환경 Ⅳ등급인 농업용수 수질기준을 초과하였으며, 총인은 0.093 mg/L로 Ⅳ등급의 수질을 나타내고 있었다. 유입하천은 총질소(1.426~3.809 mg/L)가 비교적 높게 나타나고 있어 총질소에 기준한 수질개선 방안이 요구되었다. 식물성플랑크톤 조사결과 Oscillatoria와 근연종인 Lyngbya가 우점하였으며, 둥물성플랑크톤은 대부분의 지역에서 적조현상을 일으키는 와편모충인 Gynmodinium spp., 암색편모충인 Cryptomonas spp.이 우점하였다. 부영양화도지수(TSI)를 이용한 1999년도의 시기별 영양상태 변화는 9월에 과부영양상태를 보었으며, 연도별 TSI_(M)지수는 '96년, ‘97년에 부영양, '98년의 과영양으로 영양상태가 증가하였으나, 강우가 다소 많았던 '99년에는 강우의 영향으로 다소 개선되어 나타났다. 결론적으로, 저수지의 물리구조적 유역특성 및 수리학적 특성상 만운저수지는 부영양화에 취약한 특성을 가지고 있으며, 강우량에 영향을 받고는 있으나 전반적으로 부영양화도가 증가하는 추세를 보인다. 따라서, 이와 같은 추세변화를 정확히 인식하고 그에 적절한 대책을 마련하기 위해 농업용수 수질측정망 운영이 상당히 중요하게 인식되어지며, 수질환경 특성을 감안한 합리적 운영이 이루어져야 할 것으로 사료된다. Manun Reservoir, located in Andong district, has the capacity of 2 million tons in irrigation water supply with the drainage area of 23.8 km². Manua Reservoir is over fifty year old, and shallow in depth. The ratio of drainage area (DA) to reservoir surface area (SA) as an effective physical parameter on water quality was 56.1 and was higher than those of other agricultural reservoirs. The ratio of reservoir storage (ST) to SA in Manun Reservoir was 4.79, and the mean depth was below 8 m. Both ratios of DS/SA, total area (TA)/ST and ST/SA in Manua Reservoir were relatively higher than those in other agricultural reservoir and natural lakes in Korea. These physical parameters in Manun Reservoir, however, had a eutropic potential significance. Average of COD, TN, and TP in Manun Reservoir were 11.1 mg/L, 1.426 mg/L, 0.093 mg/L, respectively. In the inflow stream of Manun Reservoir, the TN (1.426~3.809 mg/L) was higher than those in reservoir. Only Lyngbya spp. was dominant in phytoplankton for this study period, and Gymnodinium spp., Peridinium spp., and Cryptomonas spp. were dominant in zooplankton. According to the Carlson's trophic status index, Manua Reservoir was eutrophic in 1996, 1997, and 1999, and hypertrophic in 1998.

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.

한국 여성스포츠 활성화를 위한 연구

윤상화,남동현,조임형 龍仁大學校 1997 용인대학교 논문집 Vol.13 No.-

Historically women have been discriminated not only in sports but also in another fields of social life according to the social cultural backgrounds and customes. This sex discrimination is due to the lack of the opportunity to participate sports, the ideological prejudice of male diversionism and the systematic inequality uttered in the nomological, institutional, environmental aspects of society. And the social conception on male adventage and female dependence enforces the present discrimination in the women sports. Theoletically, discussion on women sports has been focused on the dogma that man governs woman in the sense of sex inequility in sports, limitation of female opportunity in sports, inequility of conservative system and the relative deprival of employment opportunity from the point of liberal, marxist, radical, socialist view. The sex discrimination is due to the social, cultural circumstance of a specific society and prejudicial cultural tradition. The cultural tradition form the idea that woman can play the role only through the family and companion because of her biological and depentent character and enforce such a sex role and social training. The social-role prejudice which began in the family and companion would be enforced and magnified through the discrimitive management of the curriculum and phisical education program at school. The sex discrimination has such a tendency of aggravation and perpetuity because of male-prejudicial news and scarcity of role-model, which have been discussed in many researches. But woman's sports were advanced quite much in accordance with feminism movements and the change of social/cultural definition on woman. In spite of all of these, there still appears to be some prejudice in the psyological, social-psychological, institutional realms. To sum up the factors which prevent woman's sports activate, Firstly, negative cognition of common people on woman's sports. Secondly, the prejudice that women are not adquite for sports activity. Thirdly, women themselves have the prejudice that sports activity makes their body manly. And to sum up the important theoletical factors concerned with the woman's sports activation, Firstly, woman has psychologically the stronger emotional intentionality than man. Secondly, woman has the weaker motivation for sports psychologically, which is due to her parents' indifference and the incorrect belief of 'womanlikehood' or 'out to be womanlike' and so on. Thirdly, because woman's participating the sports activity is influenced by intermediate group like family, the opportunity-situation became the important variable. Some conclusion for activation of Women's Sports Activation acquired in the study is as shown in the followings. Firstly, We must change the ineffective sports activities in the whole society, including the system, which places the importance in the examination at the existing school, and the physical education program which lays stress on the sudents to comply with the characteristics and interests of women in the scope of life-time sports, and the education on the leader who controls these programs effectively is urgent. Secondly,Mass Media must be interested in the sports, physical education activities of women, and show the positiveness on the program related to the women's own improvement and culture and on the public-information related to the concrete practical method.

체내 납부담의 지표로서 누적 혈중 납량과 누적 혈중 ZPP가 납 관련 신기능에 미치는 영향

윤강호,김남수,김진호,김화성,이병국 대한산업의학회 2006 대한직업환경의학회지 Vol.18 No.4

목적: 체내 납부담의 지표로서 누적 혈중 납량과 누적 혈중 ZPP가 납관련 신기능에 미치는 영향을 알아보기 위하여 678명의 납 작업자들을 대상으로 본 연구를 시도하였다. 방법: 누적 혈중 납량과 누적 혈중 ZPP는 입사시부터 매 1년간의 혈중 납량과 혈중 ZPP를 누적하여 구하였다. 입사시기가 1983년 이전인 납 작업자의 경우는 최초 혈중 납량과 최초 혈중 ZPP를 그 이전의 값으로 추정하여 구하였다. 체내 납부담의 지표로서 골중 납량과 DMSA착화납량을 측정하였으며, 최근의 납 노출 지표로서는 혈중 납량과 혈중 ZPP를 측정하였다. 신기능을 평가하는 지표로서는 임상 신기능 지표로서 BUN과 혈청 creatinine을 측정하였고, 신기능 조기지표로는 NAG (N-acetyl-D- glucosamide)와 RBP (Retinol binding protein)를 측정하였다. 결과: 혈중 납량과 혈중 ZPP의 누적지수와 골중 납량과는 결정계수(r²)는 각각 0.72와 0.567로서 유의한 상관이 있었으며 이들 누적지수와 골중 납량은 곡선형적 모델이 더 적합하였다. 신기능 지표들을 종속변수로 하고 성, 연령, 직력 및 음주와 흡연을 통제한 후 혈중 납량과 혈중 ZPP를 독립변수로 한 중회귀분석에서 혈중 납량은 4개의 신기능 지표들 중 지수 변환한 NAG와만 유의한 관련이 있는 반면, 혈중 ZPP는 지수변환한 NAG를 제외한 신기능 지표들과 유의한 관련이 있었다. 한편 신기능 지표들을 종속변수로 하고 연령 및 직력과 음주와 흡연을 통제한 후 체내 납 부담노출지표들을 독립변수로 한 중회귀분석에서 골중 납량과 혈중 ZPP 누적지수는 4개의 신기능 지표들과 유의한 관련이 있는 반면, DMSA 착화납량과 혈중 납량 누적지수는 BUN을 제외한 신기능 지표들과 유의한 관련이 있었다. 결론: 상기한 결과로 보아 혈중 납량과 혈중 ZPP의 누적지수는 체내 납부담의 지표로서 효용성이 입증되었으며, 특히 혈중 ZPP의 누적지수가 혈중 납량의 누적지수보다 체내 납부담의 대리지표로서 더 좋은 것으로 나타났다. Objective: To evaluate the possibility of cumulative blood lead and blood ZPP as surrogates of lead body burden and to investigate their association with renal function as an index of lead body burden. Methods: The study subjects comprised 678 lead workers with past blood lead and blood ZPP data from their employment. Cumulative blood and ZPP were calculated by accumulating the every year mean value of both indices from the new employment since 1983. To assess the cumulative data of lead workers who started their lead work before 1983, the years before 1983 were simulated with the first available data from 1983. Study variables for lead body burden were tibia bone lead and DMSA chelatable lead, whereas those for current lead biomarkers were blood lead and blood ZPP. BUN and serum creatinine were selected as clinical renal biomarkers, while NAG (N-acetyl-D-glucosamine) and RBP (Retinol binding protein) were selected as early renal biomarkers. Results: The association between cumulative blood lead and blood ZPP with tibia bone lead was statistically significant with determinant coefficients (r²) of 0.72 and 0.567, respectively, and their relationships were better explained by the curvilinear regression model. In multiple regression analysis of current lead biomarkers on the renal biomarkers after controlling for possible confounders (age, sex, job duration, smoking and drinking status), blood lead was associated only with log-transformed NAG, whereas blood ZPP was associated with 3 other renal biomarkers. On the other hand, in multiple regression analysis of biomarkers of lead body burden on renal biomarkers after controlling for possible confounders (age, sex, job duration, smoking and drinking status), cumulative blood ZPP and tibia bone lead were associated with all 4 renal function biomarkers, whereas cumulative blood lead and DMSA chelatable lead were associated with 3 renal biomarkers except BUN. Conclusion: Cumulative blood and ZPP were demonstrated to be good surrogates of lead burden. Furthermore, the cumulative blood ZPP was confirmed to have a better association than the cumulative blood lead.
