이두형,배공영,박소홍,강연지 한국환경농학회 1999 한국환경농학회지 Vol.18 No.2

대기오염과 병충해발생과의 관계를 규명하고자 은행나무에 SO₂가스를 처리한 후, 잎끝마름병균을 접종하여 식물의 생리·생화학적인 변화를 조사하였다. 0.1㎕/ℓ의 SO₂가스를 하루 8시간씩 7일간 은행나무에 처리한 결과 Chlorosis등의 가시피해는 나타나지 않았으나, 광합성이 대조구에 비해 40%가량 감소되고, CO₂이용효율과 수분이용효율이 감소되는 현상을 보였다. 가스처리 후 병원균을 상처접종시키고 42일 뒤 SI와 SFI의 발병도를 조사한 결과 SI가 SFI에 비해 3배 가량 빠르게 병이 진전되어 있었다. 병원균의 먹이가 되는 당의 함량은 대조구, SFI, SI간에 유의성을 보일 만큼의 차이는 보이지 않았으나, 광합성은 SI가 SFI에 비해 11%가량 저하되었다. 광합성이 저하되었음에도 불구하고 당의 함량이 유지되었으므로 탄소 고정관계를 알아본 결과 CO₂ 이용효율이 저하되지 않았음을 알 수 있었다. 이와 함께 수분이용효율이 SI에서 SFI에 비해 13.2% 증가되었다. 이상의 결과를 종합해 보면, 이온유출량 등으로 보아 SO₂가스처리로 인해 식물이 연약해져 병원균에 대한 저항력이 낮아졌고, 수분이용효율의 증가로 인해 탄소 고정이 활발하게 이루어짐으로써 당이 원활히 합성되는 한편 내부적인 변화로 인해 합성된 당의 전류가 억제되어 잎에 당이 축적되었기 때문에 SI의 발병도가 훨씬 높았던 것으로 생각된다. To examine the relationship between air pollution and occurrence of disease in plants, we investigated the alteration of physiology and biochemistry of Ginkgo biloba by inoculating with Coniothyrium sp. and fumigating with 0.1㎕/ℓSO_(-2) Visual damage did not appear but photosynthesis, CO₂use efficiency(CUE) and water use efficiency(WUE) were reduced when G. biloba was exposed to SO₂for 7days (8 hours a day). When inoculated with Coniothyrium sp., the seventies of damage in G. biloba showed a threefold difference between SO₂-treatment (SI) and SO₂-free treatment (SFI) at day 42 from initial inoculation. Little difference was observed in sugar contents that may be used pathogens feed, among control, SFI and SI. In spite of the reduction in photosynthetic rate, sugar contents and CUE were maintained. WUE was enhanced 13% more at SI than SFI. The CO₂fixation boosted because of enhanced WUE, and thus sugar synthesis was not affected. In addition, sugar transport seems to be retarded for some internal alteration. Consequently, the severity of SI was more serious than that of SFI because Coniothyrium sp. easily invades into the physical texture of G. biloba weakened by SO₂fumigation and because sugar was accumulated in leaves of G. biloba.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

방향족화합물의 무차원 헨리상수(Air/Water 분배계수 : K_(aw))를 headspace sampler(HSS)와 gas chromatography(GC)를 이용하여 318.15-355.15 K 온도 범위에서 온도를 변화시키며 측정하였으며, 이 방법으로 시료와 평형 및 채취, 분석 과정에 있어서 용질의 휘발로 인한 오차와 수작업에 의한 측정 오차를 최소한으로 줄이고자 하였다. HSS내 평형용기의 기상과 액상조성은 GC의 피크면적과 물질수지 식으로부터 계산하였으며, 이 관계식을 이용하여 benzene을 비롯한 몇 개의 방향족 화합물의 무차원 헨리상수를 온도별로 측정하였고 문헌값과 비교하여 방법의 신뢰성을 확인하였다. 또한 온도와 무차원 헨리상수의 함수관계를 통해 온도에 따른 무차원 헨리상수 값을 유추하는 방법의 가능성을 살펴보았다. Dimensionless Henry's law constants of aromatic compounds in water were measured at various temperatures between 318.15-355.15K using a headspace autosampler with a gas chromatography. This measuring system prevent, sample losses due to volatilization from equilibration, sampling, and chemical concentration analysis by a high precision headspace sampler and gives relatively accurate results. Dimensionless Henry's law constant is calculated by thermodynamic relation and the mass balance with gas chromatographic peak area. Different equilibrium concentration in gas phase was made by using different gas-liquid volume ratio in sample vial. The temperature dependence of dimensionless Henry's law constant was correlated with the classical van't Hoff equation as a function of temperature. The extrapolated data at 298.15K from correlated equation were compared with available literature data in order to test this method.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

Objective: To investigate the relationship between body mass index (BMI) and liver function abnormalities in the general population in Korea. Methods: The study subjects were 5765 persons who were received questionnaire survey and health examination of national health and nutrition survey in 1998, 20-59 years in age and had no history of viral hepatitis. BMI was categorized by quartile and abnormal liver functions were defined aspartate aminotransferase (AST) >30 U/L or alanine aminotransferase (ALT) >35 U/L in serum level. In order to identify the association of BMI and abnormal liver function, chi-square test and multivariate logistic regression analysis were used. Results: The abnormality rates of AST were 35.0% in male and 13.4% in female. The abnormality rates of ALT were 35.8% in male and 11.1% in female. After controlling for the other covariates, the multivairate logistic regression analysis showed that BMI was the significant related factor of abnormal AST (male; odds ratio=1.25; 95% confidence interval=1.15-1.36, female; odds ratio=1.14; 95% confidence interval=1.02-1.26) and abnormal ALT (male; odds ratio=1.87; 95% confidence interval=1.71-2.04, female; odds ratio=1.56; 95% confidence interval=1.38-175). Conclusions: We identify that BMI was the significant risk factor of non-viral liver disease with abnormal liver functions. A large-scale investigation will be suggested in the future to demonstrate the causal-effect issue between abnormal liver function and obesity.

One of the most important problem during summer plug plant production is the succulent growth. The possibility of controlling height of plug seedlings by temperature drop shock(TDS) was investigated in Pharbitis, Impatiens and Callistephus. The most sensitive plant to TDS was Pharbitis. By 2℃ water irrigation, height of Pharbitis decreased by 33%. Impatiens showed 16% reduction in height by 2℃ water irrigation. Callistephus showed no reduction in height by any treamtnet. In all plants, stem diameter increased about 10% by the cold water irrigation. Leaf injury such as leaf spot of Saintpaulia was not observed. These results suggested that TDS could be used for controlling height of summer plug seedlings such Pharbitis which is sensitive to TDS.

박소연,최민우 한국관광정보학회 2001 觀光情報硏究 Vol.- No.9

This study is approached with a view to forward progressive alternative of existing factor by finding out current factor on hosting of international conference in hotel. First, in 1995, there was 39.1% drop off in number of cases, in contrast to 92 cases in the previous year. This resulted, Korea to be ranked at 35th in the entire world and 9th in Asia, since 1997, there was a gradual rise of induction tendency by making 5th in Asia (95 case Hosted). From a new trend in hosting international conference, the number of cases in international event being hosted, by Korea who made progression by 7.89% on yearly average basis since '88, has not only almost doubled in number(from 216 case of '88 to 428 case of '97) but also tripled in terms of foreigners who joined the international events from 91(479 in '88 to 299, 148 in '97). Therefore, we can say this showed a rapid improvement. As a result from the above study, as considering high productivity of the additional value of the establishment for the convention in deluxe hotels. The establishment of convention hotels for the convention is needed. Therefore, a permanent personnel for reception that can support these facts are needed to be trained and to be disposed. I judge that high quality of service have to be supported by the above factors.
