Long term occupational exposure to solvent mixtures may cause adverse effects to the central nervous system with neurobehavioral symptoms. And some organic slovents have been suggested to cause impairment of tuberoinfundibular dopaminergic activity and neurochemical mechanisms controlling pituitary secretion. For the purpose of assessing neuroendocrine effects in occupational solvents exposure, hormonal study settings (shoes-manufacturing industry & fishing products industry) and compared with nonexposed controls(33 men, 85 women). Male workers exposed to solvent mixtures had significantly lower plasma level of follicle-stimulating hormone(FSH) than nonexposed male controls. While female workers exposed to solvent mixtures had significantly lower plasma levels of growth hormone(GH), and thyroid-stimulating hormone(TSH) than nonexposed female controls. The results of significant decrease in plasma concentrations of pituitary hormones(FSH, GH, and TSH) in workers exposed solvent mixtures indicate that occupational exposure to solvent mixtures may induce neuroendocrine effects through an effect on hypothalamic pituitary axis.

이종영,강승원,하명화,김중구,배삼덕,김두희,남복동 大韓産業醫學會 1996 대한직업환경의학회지 Vol.8 No.2

포항 지역 한 철강 제조업에서 1995년 1월부터 10월 사이에 실시한 정기 건강진단을 받은 남자 근로자 11,523명을 대상으로 HBsAg 및 Anti-HBs, HBeAg 및 Auti-HBe은 EIA법으로, SGOT 및 SGPT는 반응속도법(IU)으로 검사하였다. 그리고 이들 대상자에서 교육정보, 근무 형태, 음주 및 흡연습관과 간기능 이상 여부를 조사하여 다음과 같은 결과를 얻었다. 1. B형 간염 표지자의 분포를 보면 HBsAg(+)/Anti-HBs(-)는 8.1%, HBsAg(-)/Anti-HBs(+)는 60.5% 그리고 HBsAg(+)/Anti-HBs는 0.1%이었으며, HBsAg의 양성율은 8.2%, Anti-HBs 양성율은 60.6%이었다. 2. 연령에 따라 HBsAg(+)/Anti-HBs(-)와 HBsAg(-)-HBs(+)가 유의하게 증가한 반면(p<0.05), 교육정도와 근무형태에 있어서는 통계적으로 유의한 차이가 없었다. 3. 음주율은 HBsAg(+)/Anti-HBs(-)에서 HBsAg(-)/Anti-HBs(-)와 HBsAg(-)/Anti-HBs(+)의 84.6% 및 85.7%에 비해 낮지만 73.9%나 되었고, 흡연율은 HBsAg(-)/Anti-HBs(+), HBsAg(+)/Anti-HBs(-) 및 HBsAg(-)/Anti-HBs(-)에서 54.3%, 53.7% 및 53.0%의 순서로 나타났다. HBsAg(+)/Anti-HBs(-)에서 간기능 이상자가 40.1%이었으나 HBsAg(-)Anti-HBs(-)와 HBsAg(-)/Anti-HBs(+)에서도 각각 21.9% 및 18.4%를 차지하였다. 4. HBsAg(+)에서의 e항원에 대한 표지자의 분포를 보면 HBeAg(+)/Anti-HBe(-)는 31.3%, HBeAg(-)/AntiHBe(+)는 55.0% 그리고 HBeAg(+)/Anti-HBe(+)는 1.6%이었고 HBeAg(+)/Anti-HBe(-)는 연령에 따라 감소하고 HBeAg(-)/AntiHBs(-)와 HBeAG(-)/AntiHBe(+)는 증가하였다. HBsAg 양성자중 HBeAg의 총 양성율은 32.9%로 연령이 증가할수록 유의하게 감소하였다. 본 연구는 근로자의 B형 간염 표지자 조사에 있어 Anti-HBs의 검사에서는 EIA 방법으로 실시해야 하는 근거를 제시하는 것이며, 철강산업 근로자에서는 B형간염 이외의 간장질환에도 관심을 가져야 할 것으로 보이며 음주 문제에 대한 대책마련이 시급히 이루어 져야 할 것으로 생각된다. A study for seroprevalence of Hepatitis B virus markers (HBsAg, Anti-HBs, HBeAg and Anti-HBe) by EIA method and the Liver Function Test(SGOT and SGPT) using kinetic method was carried out from January to October 1995 among male workers of a major iron and steel manufacturing company located in Pohang. The results were as follows; 1. The distribution of hepatitis B virus markers showed that the proportions of HBsAg(+)/Anti-HBs(-), HBsAg(-)/Anti-HBs(+) and HBsAg(+)/Anti-HBs(+) were 8.1%, 60.5% and 0.1%, respectively. The positive rate of HBsAg in all subjects was 8.2%, whereas that of anti-HBs was 60.6%. 2. The proportions of HBsAg(+)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(+) increased significantly with age. While the distribution of hepatitis B virus markers exhibited no significant differences among the groups classified by educational background or work type. 3. The proportion of drinkers in HBsAg(+)/Anti-HBs(-)(73.9%) was significantly lower than those of HBsAg(-)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(+) (84.6% and 85.7%, respectively). The proportions of smoking for the three groups of HBsAg(-)/Anti-HBs(+), HBsAg(+)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(-) were 54.3%, 53.7% and 53.0%, respectively(p<0.01). The proportion of the subjects with abnormal liver function test in HBsAg(+)/Anti-HBs(-) was 40.1%, whereas those in HBsAg(-)/Anti-HBs(-) and HBsAg(-)/Anti-HBs(+) were 21.9% and 18.4%, respectively. 4. The distribution of e Ag markers among HBsAg(+) subjects showed that the proportions of HBeAg(+)/Anti-HBe(-), HBeAg(-)/Anti-HBe(+) and HBeAg(+)/Anti-HBe(+) were 31.3%, 55.0% and 1.6%, respectively. The proportion of HBeAg(+)/Anti-HBe(-) decreased significantly with age and those of HBeAg(-)/Anti-HBe(-) and HBeAg(-)/Anti-HBe(+) increased with age. The positive rate of HBeAg among HBsAg(+) subjects was 32.9%. In conclusion, as a screening method, EIA is recommended to test hepatitis B virus markers, especially when examining Anti-HBs more sensitively. For the workers of the iron and steel manufacturing company studied, liver diseases caused by other than hepatitis B should be given a special care including an education avoiding alcohol drinking.

The purpose of this study was to evaluate the nutrition status of calcium and iron in 116 elementary school students with different obesity index. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum calcium and iron levels were evaluated based on 24-recall dietary recalls, anthropometric measurements and blood analysis. The mean height, weight, obesity index and blood pressure of total subjects were 150.4 cm, 45.5 kg, 5.8% and 118.2/76.8 mmHg. The mean % of body fat, SBP and WHR were higher while LBM and TBW were lower in over weight subject than those of other group. The iron intake of overweight was lower than that of underweight and normal subjects(p<0.05) and average calcium intakes were only 50% and 60% respectively of the RDA for Korean. Serum calcium and iron levels of a three groups were within the normal range. There were no significant differences in serum calcium and iron concentrations among three groups, however those of underweight group were a slightly lower than those of other two groups. There were significantly negative correlations between iron of intake and weight, obesity index, systolic pressure and body fat percent. Systolic blood pressure was negatively correlated to the intakes of energy, carbohydrate and protein. Energy intake was also negatively correlated to serum iron. To summarize the results, calcium and iron intakes should be supplied to elementary school students, especially those who were overweight. These indicated that overweight group had improper mineral nutrition status. Therefore, nutrition education and profound studies from many different focus for overweight groups are highly required.

이화인,서여정 한국관광정책학회 1999 觀光政策學硏究 Vol.5 No.1

The domestic market of deluxe hotels in Seoul was segmented according to their life-style. Seven distinct life style groups were identified through a clustering procedure: (1) sense-pursuing, (2) leisure-oriented, (3) domestic sustainers, (4) convenience and ego seeking, (5) fashion-oriented, (6) social activities and achievement pursuing, and finally (7) utility seeking. The results indicated that these 7 groups significantly differ in terms of the attributes and criteria they use in choosing and evaluating hotel services as well as their patronizing behavior such as the frequency of using hotel F/B outlets, brand loyalty and brand switching behavior. In sum, it is concluded that life style is a useful variable to segment domestic hotel market and to understand the unique behavioral aspects of each segment.
