  • 3차원 날개면이 부착된 복합지지형 고속선의 정상상태에서의 조파저항을 포텐셜 기저 판요소법으로 해석하였다. 계산에 사용된 고속선은 물 속에 잠겨있는 몸체와 몸체의 중간 및 후방에 붙어 있는 3차원 날개면과 수면을 관통하는 앞, 뒤의 스트럿트로 구성되었다. 물체 표면(몸체, 날개면 및 스트럿트)에는 쏘오스와 다이폴을, 자유표면에는 쏘오스를 분포하였고, 선형화된 자유표면 조건과 방사조건을 만족시키기 위해 4점 유한차분을 이용하였으며, 날개면의 유동해석을 위해 준압력 Kutta조건(semi-linear pressure Kutta condition)을 적용하였다. 패널사이의 틈새 문제를 개선하기 위해 비 평면성이 고려된 쌍곡면 판요소법을 적용하여 각 선체 표면에서의 수치 계산 정도를 높이고자 하였다. 수치 계산 결과는 회류수조에서 모형 시험을 수행한 결과와 비교하였으며, 이로부터 본 연구에서 개발된 수치 계산법은 고속선의 최적 선형 개발에 이용 가능한 도구가 될 수 있는 것으로 나타났다.

  • This study aimed at investigating the change of fat in each body part according to the wearing of sport underwear made of specially-processed materials. in this study. 6 females made up of three early twenties, and three later thirties took part in the exercises for 12 weeks to to out the change of fat amount in body, square of body part by CT and obesity after and before an exercise. The results are as follows: In the obesity condition after and before an exercise, Roller's index shows that in case of 51 and 54, one level was lowered concerning the basic physical strength and optimal index was not changed. In the silhouette between body frames. there are differences between ages. The body fat rate decreased 35.95% on the average. and the amount of the body fat of females in twenties was more than that in thirties. The amount of body fat decrease with the lapse of exercising time, while the amount of body fat shows increased of 0.75%, which showed the minus correlation. The rate of averaged flat by CT went up after an exercise in every body part. and also the decreased value of subcutaneous fat was not proportioned to that of weight and girth. Inbody parts, the lower abdomen was shown 49.7%, navel part 47.7% and waist part 37.3% each in numerical value. In the thickness of subcutaneous fat concerning waist, the value of front-center line was the lowest, and followed by rear-center line and lateral line. 1204degree part in the navel showed the most fat layed, and the lowest fat layed was in the lateral part. Concerning the lower part of abdomen, under-skin fat was the most layed in 120degree part like that of navel part.

  • Background: Both objective body shape and perceived body image have been known to influence the mental health. The purpose of this study was to explore the relationship of a combination between actual body mass index (BMI) status and perceived body image with anxiety depressive condition (ADC) in Korean men and women. Methods: This cross-sectional study analyzed data of 26,239 subjects ${\geq}20$ years old from the National Health and Nutrition Examination Survey (2010-2014). This study performed a Rao-Scott chi-square and multivariate logistic regression analyses reflecting survey characteristics and used a variety of independent variables such as socio-demographics and health behavior factors. Results: With all independent variables considered, people with normal weight who perceived themselves as overweight were more likely associated with ADC than a referent group with normal weight who perceived themselves as normal weight, as shown for both men (odds ratio [OR], 1.52; confidence interval [CI], 1.07-2.15) and women (OR, 1.25; CI, 1.06-1.48). Meanwhile, compared to the referent group, men with underweight who perceived themselves as underweight showed a lower association with ADC (OR, 0.63; CI, 0.41-0.97), whereas women with underweight who perceived themselves as underweight showed its higher association (OR, 1.47; CI, 1.10-1.96). Conclusion: A certain group of people categorized as a combination between actual BMI status and perceived body image showed a relatively high likelihood of having ADC, and the gender difference in the likelihood of having the condition for a group was clear. Therefore, this study suggests the need to identify the group at a high risk of ADC on the basis of actual BMI status and perceived body image and to develop an appropriate mental health management program for the group.

  • Objective: The present study aimed to determine the impact of ewe body condition score (BCS) (over a range of 2.0 to 3.0) and nutritional treatments (consisting of differing herbage masses) during very late pregnancy and lactation and their potential interaction on the performance of twin-bearing ewes and their lambs to weaning. Methods: On day 142 of pregnancy, twin-bearing ewes with a BCS of 2.0, 2.5, or 3.0 were allocated to a "Moderate' or 'Unrestricted' nutritional treatment until day 95 of lactation (weaning). The nutritional treatments aimed to achieve average herbage masses of 1,200 to 1,300 kg dry matter (DM)/ha (Moderate) and 1,500 to 1,800 kg DM/ha (Unrestricted). Results: There were no three-way interactions between ewe BCS group, nutritional treatment and time for any ewe or lamb parameter. The nutritional treatments had no effect (p>0.05) on lamb birth or weaning weight. Lambs born to Moderate ewes had greater survival and total litter weight at weaning (p<0.05). Regardless of BCS group, Unrestricted treatment ewes had greater body condition and back-fat depth at weaning than Moderate treatment ewes (p<0.05). Ewes of BCS 2.0 group reared lighter lambs to weaning (p<0.05) and tended to have a lower total litter weight (p = 0.06) than BCS 3.0 group ewes. Conclusion: This study suggests farmers should aim to have all ewes with a BCS of 2.5 or 3 in late pregnancy for optimal lamb weaning performance. Furthermore, there is no benefit to lamb production of offering ewes pasture masses >1,200 kg DM/ha during very late pregnancy and lactation.

  • The transformer is major equipment in power receiving and substation facilities. Necessary conditions required for the transformer are compactness, lightness, high reliability, economic advantages, and easy maintenance. The pole-mount transformer installed in distribution system is acting direct role in supply of electric power and it is electric power device should drive for long term. Most of modem transformer are oil-filled transformer and accident is happening considerable. The mold transformers have been widely used in underground substations in large building and have some advantages in comparison to oil-transformer, that is low fire risk, excellent environmental compatibility, compact size and high reliability. In addition, the application of mold transformer for outdoor is possible due to development of epoxy resin. The mold transformer generally has cooling duct between low voltage coil and high voltage coil. A mold transformer made by one body molding method has been developed for small size and low loss. One body molding transformer needs some cooling method because heat radiation between each winding is difficult. In this paper, The thermal analysis of pole mount mold transformer with one body molding by duct condition is investigated and the test result of temperature rise is compared with simulation data.

  • Objectives The purpose of this study is to find out the relationship between mid parental height (MPH), birth weight, current growth condition of children (height, weight, BMI, body fat percentage, bone age) and final height of the future. Methods The study was conducted with 237 children, who were 12 - 14 years old. They were analyzed to find out the relationship between MPH, birth weight, height, current weight, BMI, body fat percentage, bone age and predicted height. Results 1. As MPH was increased, height and predicted height were also increased. As MPHs in girls were increased, 'bone age - chronological age' were decreased. As MPHs in girls were increased, body fat percentages were decreased. 2. As birth weights were increased, height, weight, BMI and body fat percentages were also increased in boys. 3. As body fat percentage was increased, predicted height was decreased. As 'bone age - chronological age' was increased, predicted height was decreased. As BMI was increased, 'bone age - chronological age' was increased. As body fat percentages in boys were increased, heights were decreased. As body fat percentages in girls were increased, 'bone age - chronological age' were increased. Conclusions MPH, birth weight, current growth condition (height, weight, BMI, body fat percentage, bone age) and predicted height are correlated to each other. There are some differences between boys and girls in these relationships.

  • After studying the theory of JangBu(臟腑), that is a physiology of Sasang Constitutional Medicine, in Sasang Constitutional Medicine, the author could draw a conclusion as these. 1. The basic thought of Sasang Constitutional Medicine is emphatic on the human beings itself unlike the idea of traditional Oriental Medicine, that accentuate the universe.(The traditional Oriental Medicine has a concept that the human beings follows the order of universe, but Sasang Constitutional Medicine has a different idea that human beings has the free will to the universe and newly comprehend the relationships between human beings and universe.) 2. Like the preceding, the theory of JangBu(臟腑), the physiology of Sasang Constitutional Medicine, is based on the autonomic mechanisms of human body itself. 3. The medical philosophy of Sasang Constitutional Medicine is Sasang(四象), that is Sa(事), Sim(心), Sin(身) and Mul(物). This Sasang is a classification of universe include human beings.(Sa(事) is event, Sim(心) is mind, Sin(身) is body, and Mul(物) is things. these four elements express the universe and human.) 4. The JangBu(臟腑) theory of Sasang Constitutional Medicine regard mind condition as important. The mind condition is divided into two factors. The one is Seong(性) the other is Jeong(情). The Seong(性) is an attitude toward the world, and the Jeong(情) is response to the stimulation from the world. 5. By the actions of Seong(性) and Jeong(情), the human body has different JangBu(臟腑) function, so the human body can be grouped in four constitutions. 6. Because of emphasis on mind condition, the Sasang JangBu(臟腑) theory has activism of human beings itself. 7. This activismor practical philosophy of Sasang JangBu(臟腑) theory, that is a physiology of Sasang Constitutional Medicine, gave birth to ethics or morality in Medical philosophy, that the human practice of ethics or morality bring a health and well being of human body.

  • Objective: Two series of experiments were conducted to determine how the incremental levels of sodium metabisulfite (SMB)-treated fruit and vegetable discards (FVD) in diet of Hanwoo heifers and cows affect their performance and health. Methods: In Exp. 1, 36 Hanwoo heifers were stratified by age (13.3±0.83 mo) and initial body weight (305±19.7 kg), and divided randomly to one of three diets containing 0%, 10%, or 20% SMB-treated FVD (as-fed basis). The experiment lasted 110 d, including 20 d of adaptation. In Exp. 2, 24 multiparous Hanwoo cows were divided into three groups based on age (48.2±2.81 mo) and initial body condition score (2.64±0.33). Cows in each block were assigned randomly to one of three diets containing 0%, 11%, or 22% SMB-treated FVD (as-fed basis). The experiment lasted 80 d, including a 20-d adaptation period. In both experiments, SMB-treated FVD was used as a replacement for wet brewers grain in total mixed ration (TMR). Results: Growing heifers exhibited no differences in their daily feed intake (6.58±0.61 kg/d dry matter [DM]), average daily gain (0.60±0.07 kg/d), and body condition score when they consumed the incremental levels of SMB-treated FVD. Although most blood metabolites were unaffected by treatments, blood urea-N and β-hydroxybutyrate levels decreased linearly as the SMB-treated FVD level increased in TMR. Similar to Exp. 1, minor differences were found in daily feed intake (8.27±0.72 kg DM/d) and body condition score of Hanwoo cows. Most blood metabolites remained unaffected by treatments, but blood urea-N decreased as the SMB-treated FVD level in TMR increased. Conclusion: Our findings suggest that SMB-treated FVD could be safely incorporated into the diet of Hanwoo heifers and cows, potentially improving N-use efficiency in the body while not impairing performance or health.
