Aquatic macrophyte vegetation as foodplants for waterfowl in Jukrim and Maekdobranches, Yongwon inlet and Junam reservoir was investigated from April 1984 through April 1985. These areas interrelated to the total Nakdong wintering ground for waterfowl. Aquatic macrophyte flora in Jukrim branch included 14 species of 11 genera of 9 families, and 21 species of 16 genera of 11 families in junam reservoir. In Yongwon inlet Zosterra marina was only distributed. In these areas except Yongwon inlet, dominant species was Trapa japonica and the fruits, not the leaves and stems of it was very important as food source for swans and geese. The biomass of the aquatic weed vegetation in Jukrim branch increased quickly from April to July 1984 and continued to grow until October of the same year. However, it remarkably decreased from October to November as it was consumed by migrating and wintering waterfowl. Thus, the foodplant biomass dropped sharply in the midwinter. The biomass of early April in 1985 was 1.6g??, which was only 0.8% out of total biomass in October the previous year. All above results show that aquatic plants are under heavy feeding pressure in Nakdong estuary and related area.

저수탱크의 혼화특성 평가

윤재흥,정혜원,오정우 대한상하수도학회 2003 상하수도학회지 Vol.17 No.1

Storage tanks have two types of function. One is to maximize the disinfection capability by inducing plug flow, and the other is to regulate the water quality by mixing flow completely. Hence the mixing indices to represent the flow characteristics in tanks are required to identify if the tank performs its function well. As a result of evaluating the existing indices with fluoride-tracer and dye tests, T_10/T and T_90/T_10 proved relatively good indices. However, T_10/T showed some limits to representing the characteristic of residence time distribution, and T_90/T_10 had too wide range of the values to be easily used for assessing the flow characteristics. An index proposed in this study can properly represent both the completely mixed and plug flows as well as short-circuit flow, and can be used as an index of assessing mixing characteristics.

Midazolam have been used widely as adjuvants in both regional and general anesthesia and in high risk patients in the intensive care unit. In the present study we evaluated the effect of midazolam and antagonistic effect of flumazenil on isolated rat tracheal preparations mounted for recording isometric contractile force. Trachea smooth muscle were contracted with acetylcholine (10^-5M, Ach) and potassium chloride (40mM KC1). Midazolam 5x10 exp (-6)M and 5x10 exp (-5)M produced dose-dependent relaxation and flumazenil (3.2 x 10 exp (-7)M), central antagonist of benzodiazepine, pretreatment had no significant change midazolaminduced relaxation. Midazolam probably did not relax airway smooth muscle by activatong central benzodiazepine receptors, as flumazenil did not block the concentration-related relaxation of midazolam. Our study suggests that flumazenil may be used satety for asthmatic patients who have been with midazolam, as flumazenil did not antagonize airway relaxation elicited by midazolam.

韓·美 女性의 社會的 處遇에 關한 比較 硏究 : 李朝時代와 植民地時代의 比較

尹惠源 淑明女子大學校 1976 論文集 Vol.16 No.-

In this comparative study of woman's situation between Yi-Dynasty and colonial days of America, I can find out some similarities as well as other differences inspite of different two countries, east and west. Under the authorized paternity, woman in both countries was not estimated a human-being but a mechanic which produced a boy as a inheritor of the compound family system in Yi-Dynasty, or a labor force as a worker in the field of Free-Land in American Colonies. Because woman was in the situation of Civily-Dead, she had no right to live for herself, but been subordinated to man like a salve. Thehe were two views of woman's moral which enfored woman to be subordinated and restricted within the home and social life. One was Chu-Za Confucianism in Yi-Dynasty and the other Protestantism in American Colonies. In such similarities, I can find that there were also some different kind of images of subordination of woman in both countries. In the former, woman was completely belonged to compound family system including ancesters, so she was not permited to be married again even though after becoming a widow, she had to stay in the husband's house to serve parents-in-law and to hold the memorial service of the family ancestors. The other hand, she was protected and treated hospitality at home as house-mother, not owing to her own dignity but to the ancestor's authority. In the latter, even though the moral of Protestantism taught woman to be obedient, to man and to be diligence, and abstinence, in order to build the new home and society in the New-Land, a widow was estimated to be better wife than virgin as a labore force. In conclusion, there was no place for Korean woman to stand up as an individuality, in the society tightly restricted within the tradition of Chu-Za Confucianism. But in the latter, as the time passed, woman acknowledged herself individuality, and resisted against the authorities of religion and paternity and at last she fought for woman suffrage. I think that those different images of woman's subordination in both countries, came from their different social condition and historical traditions which originated from the moral of Chu-Za Confucianism and Protestantism.

자궁근종에서의 Phospholipase C 발현에 관한연구

윤혜원 동국대학교 경주대학 1993 東國論集 Vol.12 No.-

Phosphoinositide-specific phospholipase C(PLC) is one of the key molecules in signal transduction for celular activity such as proliferation and differentiation. However, the biological significance of their molecules in carcinogenesis or tumor progression is not defined yet. Using PLC isozyme - specific antibodies, the relative contents of PLC isozyme have been examined in uterine myoma and normal myometrium. Immuno-reactive analysis revealed considerably hither levels of PLC-γ1 protein in all uterine myoma and little difference in PLC-β1, when compared to normal myometrial tissue. From Western blotting, PLC-γ1 showed 3 to 4 fold more expression in uterine myoma than that in normal myometrial tissue. There also is a linear relationship between activity and amount in PLC-γ1 increase of myoma. Taken together, the fact that the majority of uterine myoma displays elevated level of PLC-γ1 expression implies that PLC-γ1 mediated signal transduction may have significant role in proliferation and differentiation of myoma.

Objectives : This study was carried out to suggest preventive methods for hypertension in cold-exposed workers. Methods : In 11 refs·iteration industries, 68 workers working in refrigerated areas more than one time per day were selected as the exposed group, and 68 workers not exposed to cold were selected as the control group. We interviewed the subjects with a questionnaire covering occupational history, and conducted clinical and laboratory tests including measurements of blood pressure and core temperature. Results : The systolic blood pressure in the exposed group(130.0±13.3 mmHg) was significantly higher than that recorded In the control group(118.3±12.1 mmHg), as was the diastolic blood pressure in the exposed group(82.7±8.5 mmHg) versus the control group(77.4±8.7 mmHg). The core temperature in the exposed group(36.1±0.7℃) was significantly lower than that experienced in the control group (36.4±0.5℃). In logistic regression analysis, age, cold exposure severity and milk intake were significant variables, with odds ratios of 5.204(95 % CI 1.440∼18.812), 2.674(95 % CI 1.080∼6.618), and 0.364(95 % Cl 0.141∼0.942) , respectively. Conclusions : Our study suggests that cold-exposed workers have higher a higher risk of hypertension, and that their core temperature is lower. Risk factors affecting hyper-tension of cold-exposed workers include age, cold exposure severity and milk intake. For the prevention of hypertension, cold-exposed workers should minimize cold-exposure time as much as possible.

Purpose : This preliminary study was done to identify sex related characteristics and sex knowledge of high school students. Methods : 622 high school students participated in the survey living in Gangreung city area. The data collection was done from May 1st to October 31st, 2000 using the self administered questionnaires. Results : The teachers and the peer students had a critical position in high school sex education. Reproductive physiology such as relations with the opposite sex, AIDS, STI, and contraceptions should be intensified in further sex education for high school students. There were sex differences in contraception and permission with sex relationship. And the false belief regarding sex assaults and knowledge deficit in AIDS were discovered. Conclusion : Sex education program development and application are necessary based on the educational needs and attitude evaluation for the sexual health improvement of high school students. In further study, developing the reliable measurement tool and various educational methodologies will be studied which are enough for the include the sex education concepts.

Urapidil, Labetalol의 투여가 기관내 삽관시 심혈관계에 미치는 영향

신용섭,윤석화,손수창,이원형,이정은,황원재,김만수,김영주,김혜자,최세진 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.
