  • Abuse liability of ephedrine was investigated by measurement of locomotor activity and self-administration in Sprague-Dawley rats. Locomotor activity was determined in rats treated with 3, 10 and 30 mg/kg ephedrine for 14 days. Self-administration by ephedrine (0.23, 1 and 2.3 mg/kg) was examined in food-trained rats. We also examined effect of dopamine receptor antagonist (spiperone, $30{\;}\mu\textrm{g}/kg$) on the ephedrine-induced response of self-administration. Body weight was not statistically difference between control and ephedrine treatment group, but locomotor activity was dose-dependently increased. Self-administration for ephedrine was decreased in the early response (day 1 and 2) but the response was increased by higher dose of ephedrine. Self-administration was decreased by dopamine receptor antagonist (spiperone). These data showed that ephedrine increased locomotor activity and induced response of self-administration, and the effects of ephedrine were partially related to the dopaminergic system, which suggest the ephedrine may have abuse liability.

  • Self-compactability is defined as a capability of concrete to be uniformly filled and compacted in every corners of formwork by its self-weight without vibration during placing. To evaluate the self compactability of self compacting concrete, the slump flow, the time of slump flow at 500mm and U-box apparatus testing methods are used. In this research, the fresh and hardened properties of self compacting concrete using ground granulated blast furnace slag as a part of cement were investigated for the volume contents of sand in the mortar. The workability, flowing characteristics, air content and compressive strength of concrete were tested and the results were compared with the different volume contents of sand in the mortar. In the experiment, we acquired satisfactory results at the point of flowing characteristics and strengths of self compacting concrete.

  • This study compares the perceived body image of female college students in Korea and Japan as well as explains the difference in the level of self-esteem, body cathexis, body image and fashion leadership based on nationality and body. The sense of fashion leadership affected by these factors was also analyzed. A high ratio of Korean and Japanese female students perceived themselves as obese compared to actual body physique. It was shown that body was highly distorted. They showed a comparatively low level of satisfaction with appearance in contrast to their high interest in their appearance and weight. Thin bodied individuals showed a high level of self-esteem and body cathexis; however, persons with an obese body showed a low level of body cathexis. They showed high interest in appearance regardless of body physique; however, they remain unsatisfied with their appearance. Individuals with an obese body and a standard somatotype showed a high concern with weight. A high fashion opinion leadership was reciprocal to a high interest in appearance and satisfaction with appearance. Korean female students showed an indirect positive effect on fashion opinion leadership through body cathexis, self-esteem, interest in appearance, and satisfaction with appearance. A thin body showed a positive effect on fashion opinion leadership and an obese body had a negative effect. Fashion innovativeness was directly influenced persons with a high degree of self-esteem and interest in appearance. Japanese female students were directly affected by fashion innovativeness; however, Korean female students were indirectly affected by fashion innovativeness through self-esteem and interest in appearance.

  • This study evaluated the effect of four different feeds on the larval weight and survival rate of Protaetia brevitarsis seulensis (PBS) over five weeks. Four different types of feed (self-fermentation medium, RM medium, Samsung livestock medium, and bean-curd dregs medium) were given to third-instar larvae of PBS. Weight changes and survival rates of PBS larvae were measured weekly for five weeks. During the experimental period PBS larvae showed the highest growth in Samsung livestock medium, followed by bean-curd dregs medium, RM medium, and self-fermentation medium. Survival rate of PBS larvae were the lowest in bean-curd dregs medium, and then in the Samsung livestock medium. Using the Samsung livestock medium can shorten the delivery period of PBS larvae by approximately 40 days based on the larva shipped on average 75 days. Therefore, this study provides information and data on insect farming techniques useful for insect industrialization.

  • In order to give basic data to teenager's healthcare, we investigated the food habits according to BMI (Body Mass Index), life style, dietary related self-efficacy and food intake through conducting a research surveying 732 middle school students of the Kwang-ju and Chonnam areas. The results of this study were compared groups in under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the male students, height was significantly differently in the UW group as $158.2\pm0.7$ cm compared to other NW and OW groups respectively as $163.7\pm0.6$ cm and $162.6\pm0.7$ cm but in the female students there was no significantly difference within groups. Weight was significantly different between the groups in the male students, whereas there were minor differences in the female students. The average of BMI was $20.7\pm0.1$ on the male students and $20.6\pm0.1$ on the female students which were all within the average, and their obesity was increased as the school grade was higher. Under less than 30,000 won of pocket money was dominating, and most of the students were in a nuclear family. In all male and female students, the inactive hours like watching TV and using computers had no differences between groups. The difference between groups was minor on breakfast time and most of the students thought their problems on unbalanced diet. There was significant difference in the OW group in female students as they thought their problems on unbalanced diets. The frequency of snack was significantly low in the OW group of male students but there were no differences in snack and eating-out food. All students chose fruits as snack food and Korean-style food as eating out food. The OW group in male students were significantly low in the dietary related self-efficacy when they were with their families and feeling depressed but there were no differences in female students between groups. When all students were getting higher BMI, they evaluated themselves badly in their self-dietary habits. Also the more male students had non-physical activity time, the less they had the dietary related self-efficacy and the more female students had physical activity time, the higher they had the dietary related self-efficacy. In conclusion, the OW group had good habits in physical activities for weekends, meal times, frequency of snack consumption but it showed undesirable when they were low in dietary related self-efficacy. Therefore we will provide the systematic nutrition education to them through this study.

  • Objectives : Psychological comorbidities are high in patients with obesity and are associated with a variety of medical and dietary problems. This study aims to examine the association between psychological factors and obesity. Methods : This study was performed in pre-menopausal obese($BMI{\geq}25kg/m^2$, waist circumference ${\geq}85cm$) women in Seoul, in 2008 (n=35). Every patient underwent the obesity treatment program. The program included dietary and exercise education, and abdominal mesotherapy for 6 weeks. Simple anthropometry including weight, BMI and Computed Tomography (CT) including Subcutaneous adipose tissue (SAT), Visceral adipose tissue (VAT) and Visceral adipose tissue/Subcutaneous adipose tissue ratio (VSR) were done. To assess psychological factors, the Rosenberg self-esteem scale (SES) questionnaire, Beck depression inventory (BDI) questionnaire and stress response inventory(SRI) questionnaire were administered. Results : 1. All of the obesity indicators (except VSR) decreased significantly after the obesity treatment program. 2. There was a significant relationship between self esteem (SES score) and visceral obesity (VAT and VSR) measured at the end of the program. 3. During the intervention, the more weight, BMI, and subcutaneous adipose tissue decreased, the more self-esteem (SES) increased. There was no relationship between depression (BDI) and obesity. And the change in stress response (SRI) was associated with the change of deep subcutaneous adipose tissue and total abdominal adipose tissue. Conclusions : This study proves that visceral obesity may contribute to low self-esteem, and there is a possibility that the other psychological factors could also be related with obesity in Korean obese women. Individualised antiobesity therapy may be required depending on the patient's psychological characteristics and weight loss could be helpful in order to treat psychological problem in obese patients.
