This study is to examine the relation between self-consciousness and appearance management behavior; to grasp the appearance management behavior depending on self-consciousness which older women feel personally; to understand their needs more deeply; and to give support in planning and conducting marketing strategies effectively in the beauty and fashion market. The subjects of this study were aged women ranging 55 to 69 in age, living in Daegu and Geongsangbukdo. 500 questionnaires were distributed and 397 questionnaires out of 440 returned were used in the data analysis. The results through statistic analyses are following: 1. Among older women, the higher social self-consciousness group appeared to pursue six types of appearance management behavior(i.e., weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior) much more than the lower social self-consciousness group. 2. Compared with the lower private self-consciousness group, the higher private self-consciousness group appeared to care for not only weight body-shape care but also skin care, cosmetic care, and cosmetic surgery, clothing behavior with more interest in ordinary times. In terms of hair care, though, there was no significant difference between the higher private self-consciousness group and the lower private self-consciousness group. 3. There was no statistically significant difference between the higher social anxiety group and the lower social anxiety group in weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior.

The aim of this study was 1) to confirm the practical efficiency of a routine milk P4 monitoring system for postpartum reproductive management of a dairy herd, and 2) to evaluate the relationship between the blood metabolic profiles, milk quality and body weight of individual cows in the farm records, which may reflect the postpartum nutritional condition, and the time of postpartum resumption of ovarian activity of dairy cows. A total of 116 Holstein cows was used in the present study. First, during the period of Experiment 1, postpartum reproductive management based on weekly measured milk P4 concentration from individual cows was conducted. Compared with the reproductive records of the past two years without P4 monitoring, although the day from calving to first AI did not change, both the number of AI until pregnant (with P4; 1.9 times vs. without P4; 2.9 times) and the days open (with P4; 95.1 days vs. without P4; 135.8 days and 133.8 days) were significantly decreased. In Experiment 2, the measurement of blood constituents such as albumin, blood urea nitrogen, packed cell volume, ammonia, glucose, total cholesterol, non-esterified, AST and $\gamma$-GTP was performed on the blood samples taken once approximately 14 days postpartum, to monitor both health and nutritional conditions. The milk constituent parameters, such as milk protein (MP), milk fat (MF), SNF and lactose, collected from the monthly progeny test of individual cows, were used to monitor the postpartum nutritional status. Furthermore, the data obtained from the routine measurements of body weight were used to calculate the rate of peripartum body weight loss. The resumption day of the postpartum estrous cycle was assumed from the milk P4 profiles of individual cows. There was no clear relationship between each parameter from blood examination and those from resumption time. However, the cows had low values of MP, and SNF, which significantly affected the resumption of the postpartum estrous cycle. Similarly, a higher rate of body weight loss indicated a significant delay (more than 1 month) in the resumption of the postpartum estrous cycle, compared with the groups that had a medium or lower rate of body weight loss. The results of the present study demonstrated that the implementation of routine milk P4 monitoring-based postpartum reproductive management, together with milk quality parameters and routine BW data available in field conditions may be utilized as a practical approach for increasing the postpartum reproductive efficiency of a high yielding dairy herd.

The analysis of cow body parameters is important to provide some useful information fur cow management and cow evaluation. Present methods give many stresses to cows because they are invasive and constrain cow postures during measurement of body parameters. This study was conducted to develop the stereo vision system fur non-invasive analysis of cow body features. Body feature parameters of 16 heads at two farms(A, B) were measured using scales and nineteen stereo images of them with walking postures were captured under outdoor illumination. In this study, the camera calibration and inverse perspective transformation technique was established fer the stereo vision system. Two calibration results were presented for farm A and fm B, respectively because setup distances from camera to cow were 510 cm at farm A and 630cm at farm B. Calibration error values fer the stereo vision system were within 2 cm for farm A and less than 4.9 cm for farm B. Eleven feature points of cow body were extracted on stereo images interactively and five assistant points were determined by computer program. 3D world coordinates for these 15 points were calculated by computer program and also used for calculation of cow body parameters such as withers height. pelvic arch height. body length. slope body length. chest depth and chest width. Measured errors for body parameters were less than 10% for most cows. For a few cow. measured errors for slope body length and chest width were more than 10% due to searching errors fer their feature points at inside-body positions. Equation for chest girth estimated by chest depth and chest width was presented. Maximum of estimated error fur chest girth was within 10% of real values and mean value of estimated error was 8.2cm. The analysis of cow body parameters using stereo vision system were successful although body shape on the binocular stereo image was distorted due to cow movements.

Although adolescents' obesity prevalence increases recently in Korea due to Westernized dietary life, according to social and economic development, and physical activity decline, distorted body image and improper dietary habits are prevalent, because of excessive obsession with weight control, deriving from psychological impacts including appearance supremacy. This study conducted a survey on health oriented awareness and attitude related with dietary habits targeting adolescents, such as high school students and college students, younger than 24, from May 11 to May 29, 2015. In this study, 280 questionnaire copies were collected out of 300 distributed questionnaire copies, and used 269 copies as analysis data, except 11 copies of which responses were inadequate. The results of this study are as follows: First, the high school students showed higher dietary regularity than the college students. Especially, 95.5% of the college students showed very high irregularity of lunch, compared with just 4.5% of the high school students. Second, the adolescents showed distorted perceived body image in comparison with body mass index (BMI). As a result of examining BMI relationship, according to one's own perception on body type, 28.6% of the respondents perceived themselves fat, despite normal BMI, and 40.4% of the respondents perceived themselves normal, despite low BMI. Third, health behavior activities level was higher, as the regularity of breakfast (B=1.093), lunch, (B=0.650), and dinner (B=0.765) was higher. The variable affecting the most ( ${\beta}=0.372$) was the regularity of breakfast. As interest in weight control was higher, health behavior activities was lower. Because over-interest in weight control may be linked with improper dietary habits or weight control, a caution is needed. The results of this study are expected to be utilized as the basic data for the policy and health-oriented program development to improve adolescents' health behavior practice.

최근 유비쿼터스 헬스케어 서비스를 위한 무선 신체 망에 대한 연구가 IEEE 등을 중심으로 연구가 활발히 진행되고 있다. 무선 신체망은 전력제한 및 생체특성을 반영하여 멀티 홉 통신 기반의 부모노드 및 자식노드로 구성된 트리형태로 구성되는 경우가 많다. 이 경우 기존의 센서 네트워크와 달리 빈번한 신체의 움직임으로 망에 연결되어 있는 노드의 연결이 끊어질 가능성이 높으며 각 노드의 전력소모 제한으로 인해 각 노드에서 처리 가능한 노드 연결 수에 제한이 있다. 본 연구에서는 노드가 망과 연결이 끊어졌을 경우 노드가 전송할 패킷의 우선순위를 고려하여 QoS를 만족하면서 최적의 부모 노드를 선택하는 휴리스틱 알고리즘을 제안한다. 시뮬레이션을 통해 제안한 알고리즘의 성능분석을 하였으며 그 결과 본 연구에서 제안한 알고리즘이 망의 생존시간이 더 길다는 것을 확인하였다.

To clarify relationships between the abundance and biological characteristics of Pacific salmon Oncorhynchus spp., we analyzed spatiotemporal changes in fork length, body weight, and an index of relative abundance (catch per unit effort, CPUE) for pink salmon (O. gorbuscha), chum salmon (O. keta), and sockeye salmon (O. nerka) collected by research gill-nets from the T/V Oshoro-maru and the T/V Hokusei-maru of Hokkaido University in the North Pacific during 1953-2007. Populations of each species were distributed throughout the western Bering Sea, eastern Bering Sea (EB), western North Pacific (WNP), central North Pacific (CNP), eastern North Pacific (ENP), and Okhotsk Sea. Since 1970, the average body size of chum salmon at ocean ages 0.3-0.4 has generally declined in the WNP and CNP. However, the average body sizes of sockeye and pink salmon have not shown temporal changes. Chum salmon showed significant negative (positive) correlations between CPUE and body size for populations in CNP (ENP) at ocean ages 0.2-0.3 (age 0.1) for both sexes. In general, sockeye salmon also showed significant negative (positive) correlations between CPUE and body size for populations in the EB at ocean ages X.2-X.3 (age X.1) for both sexes, except in CNP at age 2. Our results suggest that better growth by chum and sockeye salmon in the early periods of their ocean life histories might produce higher abundance. This higher abundance, which might also be affected by overlapping distributions among Pacific salmon species and populations in certain seas, in turn appears to cause density-dependent declines in growth in the following ocean life history period due to the limited carrying capacity of the seas. To understand complex dynamics in Pacific salmon species in the North Pacific Ocean, research on interactions among species and populations is needed.

This study was performed to investigate the body fat-lowering effect of garlic powder in peroxisome proliferator-activated receptor ${\gamma}$ coactivator-$1{\alpha}$(PGC-$1{\alpha}$)-luciferase transgenic mice (TG). In this study, we generated transgenic mice with a PGC-$1{\alpha}$ promoter (-970/+412 bp) containing luciferase as a reporter gene. Mice were fed a 45% high-fat diet for 8 weeks to induce obesity. Subsequently, mice were maintained on either a high-fat control diet (CON), or high-fat diets supplemented with 2% (GP2) or 5% (GP5) garlic powder for an additional 8 weeks. Dietary garlic powder reduced the body weight in the GP2 and GP5 groups, compared to the CON group. Furthermore, garlic supplementation significantly decreased the plasma levels of triglycerides, total cholesterol, and leptin in the GP5 group, compared to the CON group. Specifically, luciferase activity in liver, white adipose tissue (WAT), and brown adipose tissue (BAT) was increased by garlic supplementation in a dose-dependent manner. These results suggest that the body fat-lowering effect of garlic powder might be related to PGC-$1{\alpha}$ by the increase in luciferase activity in liver, WAT, and BAT. Furthermore, transgenic mice might be useful for evaluating the body fat-lowering effect of various health functional foods.

Whole body fatigue detection is an important phenomenon and the factors contributing to whole body fatigue can be controlled if a mathematical model is available for its assessment. This research study aims at developing a model that categorizes whole body exertion into fatigued and non-fatigued states based on physiological and perceived variables. For this purpose, logistic regression was used to categorize the fatigued and non-fatigued subject as dichotomous variable. Normalized mean power frequency of eight muscles from 25 subjects was taken as physiological variable along with the heart rate while Borg scale ratings were taken as perceived variables. The logit function was used to develop the logistic regression model. The coefficients of all the variables were found and significance level was checked. The detection accuracy of the model for fatigued and non-fatigues subjects was 83% and 95% respectively. It was observed that the mean power frequency of anterior deltoid and the Borg scale ratings of upper and lower extremities were significant in predicting the whole body fatigued when evaluated dichotomously (p < 0.05). The findings can help in better understanding of the importance of combined physiological and perceived exertion in designing the rest breaks for workers involved in squat lifting tasks in industrial as well as health sectors.
