This study was undertaken to assess grade and gender differences in dietary behavior, food preference and perception about body image of students in 4, 5 and 6th grades in elementary school in Kwangju. Anthropometric data showed that mean height and weight were 137.98±6.79㎝, 32.69±6.09㎏ in the 4th grade, 144.11±6.91㎝, 36.88±7.60㎏ in the 5th grade and 151.52±7.47㎝, 42.68±8.06㎏ in the 6th grade. Height and weight of male and female students of each grade were very similar to those of the Korean standard Growth data. Females in the 5th and 6th grades were taller than those in male students, which suggested the height growth spurt in females. Furthermore, both genders showed marked variability even in the same group. All the three different obesity indices(BMI, Ro¨hrer and % of ideal body weight) showed higher value in males than in females consistently. Male respondents desired taller and heavier body shape while females perceived they were heavy and desired only taller and thinner body image. There were significant differences in satisfaction with height, weight and body image by grade(P<0.05). 36.7% of subjects responded that they did not eat despite hunger. In higher grade they felt guilty after eating sweet things. Strikingly, it was noted a small number of students tried to take a diet pills or vomited on purpose. Data on food preference showed that female did not like sweet food and pork. While male students preferred red meat and chicken. Thus result indicated that there was a great difference in food preference by gender.

This study was undertaken to assess nutritional status of the low income elderly residing in Gwangju. Anthropometric data showed that mean height of the subjects was lower than that of korean Standard growth data but weight was similar to that standard value. As the subjects became older, their heights and weights were decreased. Body mass index (BMI) in males and females were 22.9 and 24.4 respectively. However, BMI distribution showed that 56% of the elderly females under 75 were underweight. Advancing age contributes significant difference in triceps skinfold thickness in females (p<0.001). Total cholesterol level was higher in the elderly females than the males. It was found that a considerable number of subjects had anemia determined by hemoglobin and hematocrit level, which indicated un iron deficiency. Twenty-four hour dietary recall revealed that, except for phosphorus and vitamin C, all the nutrient intakes of the subjects were below 75% of Korean RDA. Surprisingly, vitamin A and riboflavin intakes of the elderly were below 50% of Korean RDA. Energy intakes of the elderly males and females were 58.7% and 59.6% of Korean RDA respectively. Unbalanced energy ratios of carbohydrate, protein and fat were noted in both genders. Nutrient intakes of females' were lower than those of males'. Thus, there was a significant gender difference in nutrient intakes. It might be further suggested that an appropriate nutritional program should be developed and implemented to improve the poor nutritional status of the low income elderly living in cities.

적정 토양 양분 및 수분 상태에서 대기 CO₂농도 상승에 따른 사과나무의 최적 광합성 온도 증가

노희명 서울대학교 농업개발연구소 2001 농업생명과학연구 Vol.5 No.-

Grwoth and photosynthetic responses of apple saplings (Malus domestica Borkh. cv. Fuji) acclimated to 3-years of exposure to contrasting atmospheric CO_2 concentrations (360 and 650 ppm) in combination with current ambient or elevated (ambient+5℃) temperature patterns were determined. Soil moisture regimes were automatically controlled by drip-irrigation scheduled at 50 kPa of soil moisture tension. For the elevated CO_2 concentration alone, overall tree growth was suppressed. However, tree growth was slightly enhanced when warmer temperatures were comnbined with the elevated CO_2 concentration. The elevated CO_2 concentration increased starch accumulation, but the elevated temperature reduced starch accumulation. Light-saturated rates of leaf photosynthesis were suppressed due to the elevated CO_2 concentration, but this effect was removed or enhanced with warmer temperatures. The elevated CO_2 concentration increased optimum temperature for photosynthesis by ca. 4℃, while the warmer temperature did not.

Storage mites are believed one of the most important allergens in farmers and rural regions. Tyrophagus putrescenitiae, belonging to storage mites, is found not only within storehouses but also in the house dust, and the third most common mites following Dematophagoides farinae and Dermatophagoides pteronyssnus in house dust in Korea. The sensitization rate to Trophagus putrescentiae was reported as high as that of house dust mite in patients visiting the allergy clinic in large cities in Korea. We experienced a 69-year-old man who had suffered from dyspnea, wheezing, and coughing for 10 years. He retired from the teaching profession, and had lived in a large city. Deajeon. The skin prick test showed a positive reaction to Tyrophagus putrescentiae and negative reactions to house dust mites. The bronchial challenge test with Tyrophagus putrescentiae showed late asthmatic reaction. We confirmed a Tyrophagus putrescentiae induced asthma in non occupational setting.

Detection of thyroid stimulating hormone receptor(TSHR) autoantibodies has clinical value in establishing the diagnosis of Graves ' disease, and in predicting its clinical course with high sensitivity and high specificity. Especially, TBII using radioreceptor assay has been widely used. Recently, for detecting thyroid stimulating antibody(TSAb), a sensitive method using human TSH receptor-transfected Chinese Hamster Ovary(CHO) cells has been developed and clinically used. The aims of this study are to determine the change and discrepancy of 2 TSHR autoantibodics in clinical course and to evaluate the correlation between 2 autoantibodies. We measured TSAb and TBII in 30 newly diagnosed and untreated patients and in 73 previously diagnosed as Graves ' disease and treated with antithyroid drug. Also we compared the changes of the antibodies in clinical course and correlation between 2 antibodies. Thes results are summarized follows. 1. In newly diagnosed patients, all of the 30 patients had positive TBII and/or TSAb. None of them had negative TBII and negative TSAb. And in newly diagnosed patients, mean TBII and mean TSAb values are 46.8% and 361%, respectively. In 73 treated patients mean values are 18. 7% and 196% each other. Therefore, newly diagnosed group has significant greater TBII and TSAb than antithyroid drug-treated group. 2. TBII was significantly different between euthyroid group and thyrotoxic group in antithyroid drug-treated patients, but TSAb was not. 3. TBII was sequentially decreased as increased medication duration, but TSAb was not shown sequential decrease as increased medication duration. 4. There was significant negative correlation between cumulative doses of antithyroid drug and TBII, but no significant correlation between cumulative doses and TSAb. 6. There was significant positive correlation between TBII and TSAb in total patients group and in antithyroid drug medication group, but not in newly diagnosed group. In conclusion, in Graves ' disease patients, detection of TSHR antibodies are clinical values in establishing the diagnosis and prediction of clinical course. A method detecting TSAb using hTSHR-CHO cells should be further studied for standardization of measurement, and for detecting the changes of TSAb in clinical course, long-term follow-up of patients are important.

본 연구의 목적은 대체의학을 선택하는 사람들의 심리사회적 변인을 다차원상에서 분석해 봄으로써 이 요인들이 어떤 방식으로 선택 과정에 영향을 미치는가를 살펴보고, 대체의학을 선호하는 사람들의 특성을 탐색해 보는 것이다. 서울시에 거주하는 일반인 200명(남 92명, 여 108명)을 대상으로 인구 통계학적 특성, 대체의학에 대한 인지도, 정통의학 기법과 대체의학 기법의 특성, 경험한 대체의학 기법의 종류, 성격변인, 대처방식, 건강에 대한 통제감, 사회적 지지를 측정하였다. 본 연구결과, 연구대상 중 약 80%는 한약을 포함한 대체의학적 치료법을 경험해본 것으로 드러났다. 또한, 대체의학적 기법을 선호하는 사람들일수록 대체의학에 대한 인지도가 높고, 연령수준이 높으며, 적극적-행동적 대처방식을 지니고 있고, 건강에 대한 내적 통제감을 지닌 것으로 드러났다. 대체의학에 대한 관심이 급격히 증가하고, 정통의학 기법과는 달리 대체의학적 치료법의 선택에는 심리적인 요인의 영향이 크다는 점을 감안할 때 앞으로 이 분야에 대한 연구가 보다 폭넓게 진행되어야 하겠다. This study examined the characteristics of people who have preference for complementary medicine and also the psychosocial factors that are related to the selection of complementary medicine. Two-hundred subjects recruited from the community were included in this study. Demographic variables, medical service characteristics, health locus of control, social support, coping style, and personality characteristics such as self-esteem, neuroticism, and hypochon-driasis were measured. It turned out that nearly 80% of the subjects had already experienced at least one alternative therapy in the past. However, past experience was not significant in predicting future complementary medicine usage. People who were older in age, had more information about complementary medicine, used active-behavioural coping styles, and had internal locus of control were more likely to use complementary medicine in the future. Recommendations for furthur research is indicated.

This study has parallelogram trajectory tracking of Three Joint Planar type Robot Manipulator. The equation of motion for the three joint planar manipulator are obtained by substituting Lagrange's energy expression into Euler-Lagrange's equation and forming the appropriate derivative. Lagrangian method allows us to obtain the dynamics equations for very complicated systems in the simplest manner possible. SISO model is used for design of the controller. The design of controllers may be considered primary controller for manipulators to track the desired trajectory under ideal conditions and secondary controller to compensates for undesirable deviations of the motion from the trajectory caused by external and internal disturbances. The aim of this paper is to evaluate the efficiency by self-tunning adaptive control and considering a characteristic of control. Through the computer simulation, obtained the following results 1) selt-tunning adaptive control is superior to PD control, 2) During the learning period, the adaptive control algorithm is searching proper estimates and controller gains. After this period, the outputs of the joints start tracking closely the desired valued.

This paper describes very fast rising high voltage pules generation using the traveling wave theory of the transmission line. This very fast rising high voltage pulse generator consists of a charging coaxial cable, a discharging switch, and a terminating resistance. The results of the study show that the rising time of pulses is very fast about 30 [nsec]. The length of the coaxial cable and the charging voltage can regulate the duration and the amplitude or the polarity of the pulse. In addition, rod to plane electrodes are suitable as a short switch and the overshoot of pulse was improved with the larger radius of the rod electrode.

This paper presents the measurement method using a spinning cylinder system for streaming electrification of transformer oil. The spinning cylinder system has a simple mechanical construction, and requires less oil compared to the other methods. Also, the effects of various admixtures on the static electrification properties of transformer oil can be easily investigated. Experiments showed that addition of the BTA reduced the streaming electrification and the polarity of static electrification was converted to negative at 50∼70[ppm] of BTA.

郭熙魯 崇田大學校 1984 論文集 Vol.14 No.1

本 論文에서는 送電線路에서 雷擊電流가 大地로 흐를 경우 時變塔脚接地抵抗에 의한 鐵塔의 過渡過電壓特性에 대하여 硏究檢討하였다. 時變塔脚接地抵抗을 갖는 鐵塔을 simulation하고 雷擊電流에 의한 鐵塔의 過渡過電壓을 Nodal Solution Method에 의해 計算하였다. 그 결과로 부터 誘導性塔脚接地抵抗의 上限値를 定常値로 決定할 경우 애자련의 CFO 電壓보다 높은 過渡過電壓을 유발할 수 있고 逆閃絡率을 計算할 때 애자련의 T-V 特性도 고려되어야 함을 알 수 있었다. This paper investigated the characteristics of transient overvoltages on the tower caused by time varying tower footing resistance in the path of lightning stroke current entering earth on transmission lines. The tower with time varying tower footing resistance was simulated and the transient overvoltages on the tower due to lightning stroke current were computed by Nodal Solution Method. From the results, it was found that the determination of the steady state values as a limit of inductive tower footing resistance causes higher transient overvoltages than CFO voltages of insulator strings and V-T characteristics of the insulator strings should be considered for computation of backflashover rate.
