최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

배상수,이훈재,이창옥,조희숙 韓國保健敎育.健康增進學會 2003 보건교육건강증진학회지 Vol.20 No.1

The objectives of this study were to verify the determinants of regular exercise behavior in female worker by applying a modified Theory of Planned Behavior. The variables investigated for this study were health status, health concern, health habit, attitude (7 items), subjective norm (3 items), and perceived behavioral control( 5 items). Data was collected from 204 female workers using a self-administered questionnaire. The results of this study were as follows. 1) Regular exercise behavior was significantly influenced by perceived behavior control for time, pleasurable attitude, and the subjective norm of their colleagues. 2) A modified Theory of Planned Behavior is particularly useful in explaining exercise behavior of female workers. We suggest that health care providers should focus on not only attitude and social norms but also perceived behavioral control in order to improve the exercise behavior of female workers.

백서에 있어서 가령에 따라 악관절 원판에 가하여지는 기계적 부하의 변화에 따른 악관절 원판의 형태, 탄성섬유 및 세포의 미세구조의 적응등의 변화양상을 관찰하기 위하여, 생후 1일, 7일, 17일, 27일, 55일, 1년 이상군의 백서의 악관절 부위를 적출하여 광학 및 전자현미경으로 관찰하여 다음과 같은 결론을 얻었다. 악관절 원판의 형태는 1일 및 7일군에서는 중앙부의 얇은 부위가 전후방으로 상당히 길게 뻗쳐 있고 전부 및 후부의 최대 풍융부를 향한 경사가 완만하여 하악와 및 하악과두에 적합되지 않는 양상을 보였으나, 17일군부터는 전부 및 후부가 하악와쪽으로 풍융해짐과 동시에 중앙부의 얇은 부위가 전후방으로 좁아지고 전부 및 후부의 최대 풍융부를 향한 경사가 급하여져, 악관절 원판이 하악과두를 감싸는 형태를 취하여 하악와 및 하악과두에 적합되어 가는 양상을 보였다. 가령에 따라 세포밀도는 점점 감소하였으며, 1일 및7일군에서는 세포내 골지장치, 과립성 내형질망, 유리 리보솜 등의 세포질 및 세포간 기질을 활발하게 합성하는 세포 소기관들이 발달 되어 있었으나 세포질내 세사는 발달되어 있지 않았다. 17일, 27일 및 55일에서는 기질합성에 관여하는 세포 소기관의 발달과 아울러 손가락 모양의 세포돌기, 용해소체, 사립체등의 세포간 기질의 개조에 관여하는 세포 소기관이 발달된 세포가 다수 관찰되었으며, 가령에 따라서 세포질내 세사가 점점 축적되어지는 양상을 보였고, 섬유성 물질에 둘러 싸인 chondroid cell들이 증가하였다. 1년이상군에서는 대부분이 세포가 chondroid cell로 구성되어 있었으며 세포질내의 대부분을 세사가 차지하고 세포내 소기관이 거의 발달되지 않는 등 대사 활동이 미약하며 주로 기계적 부하에 적응하기 위한 구조로 이루어져 있었으며 때로는 변성과정에 있는 세포도 다소 관찰되었다. The purpose of this study was to investigate changes in the shape and ultrastructrue of the articular disc of the rat mandibular joint with aging. Mechanical stress applied to the articular disc changes during neonatal, suckling, juvenile, adult and senile stages. Mandibular joints of 6 groups of rats (1-,7-,17-,27-,55-day and over-1-year groups) were removed en bloc and processed for light and electro microscopic study. The changes in the shape of articular disc were examined by light microscope in each group. Structural and ultrastructural changes in the articular disc were examined by light and electron microscope in each group. The results were as follows: In the 1-day and 7-day groups, the articular disc was long and slender in shape and the articular disc was not fitted with the shape of the mandibular fossa and condyle. However, after that time, the anterior and posterior portions of the articular disc were more bulged and the middle portion was shorter and biconcave. Thus the articuler disc was well fitted with the shape of the mandibular fossa and condyle. The cell density decreased wth aging. In the 1-day and 7-day groups, the Golgi apparatus, rough endoplasmic reticulum and free ribosome, which are involved in the synthesis of intracellular and extracellular matrix. were developed. In the 17-day, 27-day and 55-day groups, not only the cell organelles involved in the synthesis of the intracellular and exracellular matrix but also the cell organelles involved in the remodeling of the extracellular matrix(i.e., finger-like cell process, lysosome and mitochondria) were well developed. With advancing age, intracytoplasmic microfilaments were more accumulated and condroid cells increased. In the over-1-year group, the majority of cells of the articular disc were chondroid cells. The majority of cytoplasmic compartment were filled with intracytoplasmic microfilaments and cell organelles were not developed. Therefore, metabolic activites of the cell was markedly reduced and cells contained structures enduring mechanical stress, and cells which were in the process of degeneration were observed occasionally.

The purpose of this study was to evaluate the effect of cellular activity on PDL cells dependent on intermittent and continuous compressive force by determining the alkaline phosphatase activity. An intermittent and continuous compressive force were applied on PDL cells at the confluent stage. The alkaline phosphatase activity was measured on control and experimental groups every 24, 48, 72hours. The experimental group were consist of continuous and intermittent compressive group which were compressed by 300g/㎠ of diaphram pump. The intermittent compressive group was connected by timer which was worked on 10 minutes and off 10minutes. The results were as follows; 1. The alkaline Phosphatase activity of intermittent compressive group was lower than control at 24 hours(p>0.05). 2. The alkaline Phosphatase activity between each groups showed no significant differences at 48hours. 3. The alkaline Phosphatase activity of continuous compressive group was significantly higher than control group at 72 hours(p>0.01).

To evaluate the degree of bone mineral density according to physical activity, lifestyle in pre- and postmenopausal women. The subjects were 951 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to Januaty, 2001. The test for bone mineral density. The physical activity and life style were evaluated by questionaire through interview. The results were summarized as follow. 1) The prevalence rates of reduced bone mineral density and osteoporosis in premenopausal women were 23.8% and 1.6%, respectively. However, these values were increased to 46.1% and 28.1% in postmenopausal women. 2) The regular exercise was revealed to have preventive effect for osteoporosis in pre- and postmenopausal women. Among the types of exercise, the most effective exercise was bowling and moderately effective exercise was swimming on prevention of osteoporosis, however, bare hand physical exercise was not significant effect on bone mineral density. 3) The risk for reducing bone mineral density was decreased in women who have higher educational background and income in pre- and postmenopausal. The bone mineral density was highest in white color worker and lowest in blue color worker. 4) The premenopausal women who favor meat were revealed higher bone mineral density than the women who favor vegetable. The women who have drunk none or small amount of alcohol were revealed increased bone mineral density and smoking was a risk factor for osteoporosis. These results suggested that to prevent osteoporosis, the systemized program for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

The purpose of this study is to show the influence of congruity with Ads, levels of arousal and operating effect of amount of message information on perception of Ads durations and effects in the traits of background music of radio Ads. In this study, 168 subjects of male and 208 subjects of female were conveniently sampled, and randomly assigned to one of 8 conditions in a 2(congruity, high/low) × 2(amount of information, high/low) × 2(levels of arousal, high/low) factorial design. The results of this study showed that there were main effects of the levels of arousal and amount of information, that is, under the 'condition of low arousal' and 'condition of high congruity condition', there were high scores in the Ad duration the longer. Under 'high congruity condition', there were high scores in the Ad effects consistently, only in the purchase intentions there were interaction effect between amount of information and congruity, therefore operation effect of information was confirmed. There was marginal interaction effect between congruity and amount of information in the Ad effects. Also, there was main effect in the brand attitude, that is, under 'high arousal condition', subjects had the more positive attitude but it is contrary to the hypothesis. And under 'high amount of information', subjects had the more positive attitude in the brand attitude, but it is the results not to be expected by the hypothesis. Finally, implications, limitations and further research about this study were discussed.

플라즈마 아크 광원을 사용하는 광중합기를 저출력 할로겐 광원을 사용하는 전통적인 광중합기와 비교 평가하기 위하여 세 종류의 복합레진을 두께가 2, 3, 4, 5mm인 몰드에 충전하고 레진 상면을 할로겐 광으로 40초간 플라즈마광으로 3, 6, 9초간 조사한 후 레진 상면과 하면의 표면미세경도를 각각 측정하였다. 레진시편 상면의 표면경도와 하면의 표면경도 간의 차이는, 두께 2mm 시편에 할로겐 광을 40초간 조사하였거나 플라즈마광을 9초간 조사한 경우들을 제외하고, 모두 유의하였다(P<0.05). 레진시편 상면의 표면경도는 전체 실험군들에서 서로 유의한 차이가 없었다. 레진시편 하면의 표면경도는 전체적으로 보아 할로겐 광을 40초간 조사한 군들에서 가장 높았고 플라즈마광의 조사시간이 감소함에 따라 감소하였으며 레진시편의 두께가 증가함에 따라 감소하였다. 이상의 결과는 복합레진의 중합깊이 측면에서 볼 때 3, 6, 9초간 조사하는 고출력 플라즈마광의 중합능력이 40초간 조사하는 저출력 할로겐광의 중합능력에 미치지 못함을 시사한다. The purpose of study was to compare the plasma are light with the halogen light in compostie resin curing. Three composite resin materials(Z-100. 3M, USA; Tetric Ceram. Vivadent, Liechtenstein; SureFil, Dentsply, USA) were filled in the teflon molds (4mm in diameter and 2,3,4,5mm in thickness) and cured with esther the conventional low-intensity light curing unit with a halogen lamp (Optilux 360, Demetron, U.S.A) for duration of 40 seconds or with the high-intensity light curing unit with a plasma are lamp (Flipo, Lokki, France) for duration of 3, 6, and 9 seconds. The intensity of halogen light was about 370mW/cm2 and that of plasma light was about 1,900mW/cm2. After one week, the surface hardnesses of both the top and the bottom of the resin samples were measured with a microhardness tester(MXT70, Matsuzawa, Japan). There ware significant differences in the hardness between the top and the bottom of the resin samples except the 2mm thickness samples cured by halogen light for 40s or by plasma light for 9s. There was no significant difference between the hardness values of the top surfaces of the thickness groups. The hardness values of the bottom surfaces decreased as the curing time decreased and as the thickness of resin samples increased, and the three kinds of resin composites showed similar patters. The results suggest that the halogen light for 40 seconds might be able to cure greater depth of resin composites than the plasma light far 3, 6, or 9 seconds.

배용철,경희문,장병천,성재현 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.4

This study was conducted to examine the changes in the shape of the Sprague-Dawley rats' articular disk following postural hyperpropulsion by observing their articular specimens through light and electronic microscopes after following 2-week and 4-week postural hyperpropulsion from their four weeks of age. The findings of this study are summarized as follow. It was shown that as compared with the control group, the experimental group indicated a significant increase in thickness of the 2-week groups' anterior and posterior portion of the articular disc. The experimental group showed statistically more significant increase in thickness of the 4-week groups' anterior portion of the articular disc than the control group. Light micrograph showed that the experimental group had more fibroblast in the anterior portion of the 2-week and 4-week groups than the comparing group. The 2-week groups showed in the findings through the electronic microscope that there were found the well developed and dilated RER which see-ms to actively synthesize the extracellular matrix including collagen, the cells with the well developed RER without distention which seems to actively synthesize the intracellular microfilaments due to the well developed free ribosome, and the typical chondroid cells. In addition, there was more fibroblast cell with the distended and well developed RER in the anterior area of the experimental group than that of the control group while fibroblast with the well developed RER and free ribosome was quite abundat. Based on the above result of this study, it was shown that the functional hyperpropulsion of the mandible causes the changes in the nature of the mechanical load to the certain portion of the articular disk. As a result, it seems that there may be occurred some changes in morphology of the disc by adaptation or confrontation with these changes at the cellular level.

성재현,배용철,박매자,주강,경희문 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.3

The purpose of this study is to investigate the effect of loss of incisal function on the thickness, growth activities, ultrastructure of the condylar cartilage and on the muscle fibers of masseter superficialis, anterior belly of digastric muscle in the growing rats. 37 day-old-rats of which incisors had been trimmed every day received soft diet from weaning and were studied by the autoradiography, electron microscopy and muscle histochemistry. The results obtained were as follows ; The thickness of the fibrous, proliferative layer in superior, posterosuperior portion of the condylar cartilage was significantly(p<0.01) reduced in experimental groups and the decrease rate of fibrous layer thickness was greater in posterosuperior portion than in superior portion of cartilge and was greater than in proliferative layer. In normal group, more cells of posterosuperior portion moved more rapidly towards the medullary cavity. In experimental group, the labelling index of posterosuperior portion was decreased in proliferative layer at 2 hours, in transitional layer at 1, 2 days, in hypertrophic layer at 4 days after injection relative to posterosuperior portion of control group. But labelling index of superior portion was not different form that of control group at all time course after injection. From the muscle histochemistry, the diameter of type IIB fibers in masseter superficialis muscle, type ⅡA, type IIB fibers in anterior belly of digastric muscle decreased significantly(p<0.01) relative to controls in experimental group. From electron microscopic study, in the fibrous layer of the posterosuperior portion of condylar cartilage in normal group, many fibroblast like cells near the joint cavity showed extensive remodelling activities in ultrastructure. There was no morphological changes between experimental and control group in all cartilage cell layers of superior portion but cells near the joint cavity in fibrous layer of posterosuperior portion of experimental group showed morphologically inactive state relative to control group.
