Objective : The purpose of this study was to assess the effect of job strain on stress and health status among elementary school teachers. Methods and Material : The subjects in this study were 300 teachers who were selected from among 588 teachers in 13 out of 42 elementary schools in the city of Gimhae. Through the questionnaire, demographic characteristics, Karasek's Job Content Questionnaire(JCQ) and the Psychosocial Well-being Index (PWI) to assess their occupational characteristics and psychosocial stress level were surveyed. Medical checkup results of them were adopted to measure their Health status. Results : 24.9 percent of the general teachers were low strain group, and 16.3 percent of them were high strain group. In the senior teachers, 19.7 percent belonged to a low strain group and 21.3 percent belonged to a high strain group. In regard to health status, more senior teachers than junior teachers suffered from obesity(24.6%) and diabetes(11.5%) (p<0.O5), and they also were higher in DBP(p<0.057), total cholesterol(p=0.039) and blood sugar level(p=0.000), the low strain group perceived more social support(p=0.000), and the high strain group felt bigger physical overload(p=0.000). Concerning psychosocial stress, the low strain group was more aware of teacher social role and put more confidence in themselves(p=0.004). The high strain group was more depressed(p=0.001), but no difference was detected in health status. The health status difference between the high strain and low strain groups was significant in depression of psychosocial stress(OR=3.823, 95%CI=1.584-9.224). Conclusion : The senior teachers group was more morbid to obesity, diabetes and hyperlipidemia, which implies that some measure should be studied to help senior teachers manage those diseases properly. The high strain group suffered more from physical overload and was high 'Social support'. Therefore it's required for high strain group to be given more support from colleagues and supervisors, and a stress management program should be implemented to reduce their psychosocial stress.

Al-Mg-Si合金의 時效擧動에 미치는 加工熱處理의 影響

趙顯麒,李基大,朴定國 慶北大學校 1980 論文集 Vol.30 No.-

Effects of Thermo-Mechanical Treatment(TMT) on ageing behaviours in Al-Mg-Si alloy is investigated by means of tensile test, hardness measurements and transmission electron microscopy. The maximum 0.2% proof stress of the TMT materials in final ageing is higher by 10%∼20% than that of the two-step aged materials. The strength of TMT materials also increases more rapidly than that of two-step aged materials. The maximum 0.2% proof stress of the TMT materials with pre-ageing is higher than that of the TMT materials without pre-ageing. The strength of TMT materials increases with rising pre-ageing temperature, and it decreases with rising final-ageing temperature. Consequently, this type of TMT would have some practical significance in improving the mechanical properties of 6061 alloy.

Abstract-In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxatriol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

상악동에 발생한 국균증 2례

조용석,김경원,박현진,강지연,이건국,신향미 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.1

국균증은 토양, 유기체 그리고 모든 형태의 유기물 잔사에 광범위하게 존재하는 국균 (Aspergillus) 속에 의하여 발병한다.이 균의 포자는 공기 중에서 전염될 수 있으므로 가장 흔한 감염 진균 중 하나이다.부비동에 발생한 국균증은 초기 임상 증상이 만성 부비동염과 유사하며, 방사선 사진 등을 이용한 검사상도 일반 세균성 감염과 구별하기가 매우 어렵다.대개는 병리조직학적 검사로 국균을 확인해서 확진을 내리게된다.국균증의 치료는 외과적으로 상악동내의 병소를 완전히 제거하고 비강에로 충분한 공기를 통기시키는 것이 가장 중요하며 보조적으로 전신적인 항진균제를 사용해야한다. 증례는 40세와 24세인 여자 환자들로서 전신적으로는 건강했으며 임상적 방사선적으로 만성 상악동 증세를 보였다.상악동 근치술을 시행하면서 국균종으로 여겨지는 암갈색 덩어리들이 관찰되었고 술 후 병리조직검사상 국균증으로 진단되었다.국균증으로 진단 후 보조적으로 전신적 항진균제를 투약하였으며 재발없이 치유되었다. Aspergillus is a fungus of the Acetomyces class that is most commonly encountered in the human environment.Aspergillosis of the maxillary sinus is not common and it requires special consideration to diagnose and eradicate. The disease is characterized by a wide range of initial symptoms, and should be considered as a possible diagnosis in sinusitis refractory to antibiotics and antral lavage. Generally the diagnosis of sinus aspergillosis can be confirmed by histologic examination, however, characteristic radiographic appearance such as coherene of radiodense sinus concretions can be found by careful examination of the radiograms. The choice of treatment of maxillary sinus aspergillosis is radical surgery with adjunctive systemic antifungal therapy. We experienced two cases of maxillary sinus aspergillosis, which initially diagnosed as chronic maxillary sinusitis and showed a necrotic mass intraoperatively and histologically diagnosed as aspergillosis.We reports theses cases with review of literature.

茵蔯蒿가 흰쥐 肝조직내 Na^+·K^+ -ATPase 活性에 미치는 영향

金柱賢,申國鉉,趙台淳 成均館大學校 科學技術硏究所 1987 論文集 Vol.38 No.2

In order to investigate the effects of Artemisia on bile flow, the bile volume and the activities of Na^+·K^+-ATPase in liver plasma membrane and liver homogenate were examined in rats orally administered methanol extract of Artemisiae messer-schmidtiana Besser var. viridis Besser for 3 days. In the case of bile juice, the flow rate was increased 30∼70%. The activities of Na^+·K^+-ATPase was increased to 2.5 fold in liver homogenate and 2.1 fold in liver plasma membrane. On the other hand activities of Mg^++-ATPase was slightly increased in both liver homogenate and liver plasma membrane.

탈지 환원유에서 Bifidobacterium longum의 호기성 고농도 배양에 관한 연구

구동환,하상우,조수현,박기문,김동운,강국희 성균관대학교 생명과학자원연구소 1997 生命資源科學硏究 Vol.4 No.1

The objectives of this study were to investigate the optimal condition for growth and highly concenterated culture of Bifidobacterium longum (Bif longum). The effects of additives were compared with titratable acidity and viable cell counts, and 10% reconstituted skim milk (no additive) was used as a control. Correlation coefficient for the growth of Bif. longun between CO_2 anaerobic jar method and overalaid medium method was R=0.99. When 1% Bif. longurn was inoculated on 12%, 14%, and 16% reconstituted skim-milk, viable cell counts were 8.60, 8.89, and 8.93 Log CFU/ml, respectively. When Lactose, Glucose, Glucosamine, Fructose, Peptone, N-acethyl-D-glucosamine, D-galactose, and liver extract were added to 16% reconstituted skim-milk, the viable cell counts were 8.61, 9.05, 9.15, 9.24, 8.82, 9.75, 9.17, and 9.64 Log CFU/ml, respectively. Therefore, D-galactose, liver extract, and N-acethyl-D-glucosamine were selected as final additives. When Bif longum was inoculated on Fermentor-I (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% D-galactose and 0.5% liver extract), Fermentor-II (16% reconstituted skim milk containing 0.190% yeast extract, 0.590% N-acethyl-D-glucosamine and 0.5% liver extract), Batch culture-I (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% D-galactose and 0.5% liver extract), and Batch culture-II (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% N-acethyl-D-glucosamine and 0.5% liver extract), viable cell counts were 10.46, 9.37, 9.03, and 8.83 Log CFU/ml, respectively. Although liver extract was the important additive for the highly concentrated culture of Bif. longum in this study, it caused serious off-flavor when liver extract-1 (contained cell mass) was added to Fermentor culture. However, flavor was improved when liver extract-2 which was removed cell mass, was used instead of liver extract-1. Addition of 2% liver extract-II and 1% D-galactose had the similar effect with addition of 0.5% Liver extract-I and 0.5% D-galactose on the growth of Bif. longum.
