이 실험의 목적은 침엽수(Paraserianthes falcataria)와 활엽수(Shoreasp) 골목에서 두 개의 Ganoderma lucidum 균주의 자실체 발생과 성장을 연구하고 자실체의 organic germanium 과 crude ganoderic acid 함량을 측정하기 위함이다. 두 개의 Ganaderma lucidum중 하나는 인도네시아 본지에서 분리한 것이고 또 다른 하나는 Fungi Perfecti, USA에서 구입한 것을 사용하였다. 일반적으로 활엽수에서 생성된 자실체의 농도가 침엽수에서 자란 것보다 훨씬 높다. 두 종류의 골목 모두에서 상업용 균주에서 생산된 자실체의 organic germanium 농도가 인도네시아의 균주에서 생산된 자실체의 organic germanium 농도보다 높았다. 이에 반하여 버섯 자실체의 crude ganoderic acid 농도는 두 개의 균주로부터 생산된 자실체에서 거의 같은 농도를 보였다. 인도네시아 균주는 상업용 분리균주와 비교했을 때 생산된 자실체의 총 organic germanium과 총 crude ganoderic acid의 생산성이 높았다.

The purpose of the present research is to determine, for a sample of female college students, the effects of body-cathexis and importance of ideal body image on satisfaction with ready-to-wear. The sample included 177 female college students aged from 18 to 25. To measure the variables, an instrument was developed based on previous studies. Body-cathexis and importance of meeting the ideal body image were measured for five areas of body parts; head/upper body, lower body, height, weight, and torso. Satisfaction with ready-to-wear includes satisfaction with the fit at pant length, thighs, hips, waist, bust, and neckline, and with the variety in ready-to-wear. Research hypotheses were tested using multiple regression. The results showed that there was a positive impact of body-cathexis for a specific body area on ready-to-wear satisfaction which is related to the body area. The effect of importance of meeting the ideal body image on ready-to-wear clothing was different in regard to different areas of body parts.

Purpose: This study was to examine the effect of an obesity management program on the body weight, body-mass index, and physiological index of obese female high school students. Method: Students from one school were selected as the experimental group, and students from another school as a control group so the latter group wasn't exposed to the experiment. The experimental group and the control group were each organized with 20 students. The experimental group received 60 minutes of behavior modification once a week, for eight weeks. Result: The Body weight, and Body mass-Index of the experimental group significantly decreased after the obesity management program. Total-cholesterol, T-G, and LDL-C significantly decreased and HDL-C increased in the experimental group. Total-cholesterol, T-G, LDL-C and HDL-C between the experimental group and control group showed significant differences. Conclusion: These results indicate that the obesity management program had a great effect on decreasing the body weight and body-mass index of the female obese high school students, normalizing their physiological index. In conclusion, this program turned out to be one of the safest and most effective obesity-management methods that could be applied to female high school students.

Purpose. The purpose of this study was to investigate the relationship between body image, self-esteem, and family strengths in female university students. Methods. One hundred ninety nine female university students participated in data collection. Data on body image, self-esteem, and family strengths were collected via questionnaire between April 2013 and May 2013. Data analysis was done using PASW 18.0 program and included one-way ANOVA, independent t-test and Pearson correlation coefficients analysis. Results. The mean score of body image was 24.20, self-esteem was 25.30, and family strengths was 83.71. Results showed a positive correlation among body image and self-esteem(r=.19, p<.001), and family strengths(r=.16, p<.001). Conclusion. The results indicate that it is necessary to increase body image, self-esteem, and family strengths among female university students. To ensure resonable body image in female university students, self-esteem, and family strengths should be reinforced.

Purpose: This study was conducted to compare the postural habits, body image, and peer attachment of adolescents with idiopathic scoliosis and healthy adolescents, and to examine the correlation between body image and peer attachment in each group. Methods: Eighty-three adolescents with idiopathic scoliosis and 83 healthy adolescents were recruited from 4 middle schools located in W city. Data were collected from November 22 to December 6 2010 using a structured questionnaire including items about postural habits, body image, and peer attachment. Data were analyzed using descriptive statistics, $X^2$-test, independent t-test and Pearson Correlation Coefficient. Results: Compared to healthy adolescents, adolescents with idiopathic scoliosis were more likely to use one hand, to lean back while seated, and to put weight on one leg while standing. The score for body image was significantly lower for adolescents with idiopathic scoliosis compared to healthy adolescents, but peer attachment was not significantly different between the two groups. Body image was significantly correlated with peer attachment only for the adolescents with idiopathic scoliosis. Conclusion: Interventions to promote balanced postural habits in adolescents with idiopathic scoliosis are needed. Information on body image and peer attachment for these adolescents should also be considered when developing interventions.

This paper deals with the development of biomechanical model on a seat with backrest support in the vertical direction. Four kinds of biomechanical models are discussed to depict human motion. One DOF model mainly describes z-axis motion of hip, two and three DOF models describe z-axis of hip and head, and while nine DOF model suggested in this study represents more motion than the otehr model. Three kinds of experiments were executed to validate these models. The first one was to measure the acceleration of the floor and hip surface in z-axis, the back surface in x-axis, and the head in z-axis under exciter. From this measurement, the transmissiblities of each subject were obtained. The second one was the measurement of the joint position by the device having pointer and the measurement of contact position between the human body and the seat by body pressure distribution. The third one was the measurement of the seat and back cushion by dummy. The biomechanical model parameters were obtained by matching the simulated to the experimental transmissiblities at the hip, back, and head.

The Primary type of swinging motion in human movement is that which is characteristic of a pendulum. The two types of pendulums are identified as simple and compound. A simple pendulum consist of a small body suspended by a relatively long cord. Its total mass is contained within the bob. The cord is not considered to have mass. A compound pendulum, on the other hand, is any pendulum such as the human body swinging by hands from a horizontal bar. Therefore a compound pendulum depicts important motions that are harmonic, periodic, and oscillatory. In this paper one discusses and compares two algorithms of Newton's method(F = m a) and Euler's method (M = $I{\times}{\alpha}$) in compound pendulum. Through exercise model such as human body with weight(m = 50 kg), body length(L = 1.5m), and center of gravity ($L_c$ = 0.4119L) from proximal end swinging by hands from a horizontal bar, one finds kinematic variables(angle displacement / velocity / acceleration), and simulates kinematic variables by changing body lengths and body mass. BSP by Clauser et al.(1969) & Chandler et al.(1975) is used to find moment of inertia of the compound pendulum. The radius of gyration about center of gravity (CoG) is $k_c\;=\;K_c{\times}L$ (단, k= radius of gyration, K= radius of gyration /segment length), and then moment of inertia about center of gravity(CoG) becomes $I_c\;=\;m\;k_c^2$. Finally, moment of inertia about Z-axis by parallel theorem becomes $I_o\;=\;I_c\;+\;m\;k^2$. The two-order ordinary differential equations of models are solved by ND function of numeric analysis method in Mathematica5.1. The results are as follows; First, The complexity of Newton's method is much more complex than that of Euler's method Second, one could be find kinematic variables according to changing body lengths(L = 1.3 / 1.7 m) and periods are increased by body length increment(L = 1.3 / 1.5 / 1.7 m). Third, one could be find that periods are not changing by means of changing mass(m = 50 / 55 / 60 kg). Conclusively, one is intended to meditate the possibility of applying a compound pendulum to sports(balling, golf, gymnastics and so on) necessary swinging motions. Further improvements to the study could be to apply Euler's method to real motions and one would be able to develop the simulator.

The purpose of this study was to examine differences in clothing shopping orientation among female adults according to their level of self-esteem and body cathexis. The subjects included 460 women ranging in age from 20 to 69, living in the Daegu area. The data was analyzed by frequency, factor-analysis, mean calculation, ANOVA and the Duncan-test using the SPSS-package. The overall results are as follows: First, clothing shopping orientation fell into five categories: 'hedonic', 'trend conscious', 'store-patronizing', 'economic', and 'independent' shopping orientation. Second, there were measurable differences in clothing shopping orientation related to one's level of self-esteem. Third, there was a significant difference in clothing shopping orientation according to the one's level of body cathexis. It appears that high levels of body cathexis do predict a tendency towards a more 'independent' clothing shopping orientation.

This paper investigates two-hop extension communication in wireless body area networks. Many previous studies have demonstrated that two-hop extended topology outperforms single-hop topology. Although many researchers have proposed using two-hop extension communication to improve link reliability, no one has considered using a relay selection algorithm or provided a suitable solution for wireless body area networks. The design goal of the proposed algorithm is selecting a proper relay node to retransmit failed packets distributively. The proposed algorithm configures the carrier sensing period to choose one relay node promptly without requiring additional interaction. We analyze the link conditions corresponding to various body postures and investigate which factors are proper to determine the carrier sensing period. The empirical results show that the proposed algorithm reduces the expected number of transmissions required to deliver a packet successfully.
