  • The current study was conducted to determine the optimum length of feed withdrawal for pre-harvest broilers. A total of three hundred broilers were sampled from an industrial population, and 30 chicks for each weight group (e.g., 1.5 and 2.5 kg) were randomly assigned to feed withdrawal treatments for 0, 3, 6, 9 and 12 h. Weight loss, yield, muscle pH, objective meat color and weights of gastro intestinal contents, crop, gizzard, provenriculus, small intestine, caecum, and rectum were determined. Live weight loss was significantly (p<0.05) increased as length of feed withdrawal extended. A significant (p<0.05) carcass yield for both 1.5 and 2.5 kg groups coincided after 9 and 6 h feed withdrawal, respectively. Net weights of intestinal contents for crop and gizzard were significantly (p<0.05) reduced by 6 h, and the reduction for proventriculus and small intestine occurred from 3 h. A noticeable effect of feed withdrawal on pH for breast muscle at 3 h postmortem occurred only when chicks were fasted for 3 h of which pH (6.05) was significantly (p<0.05) higher than that for other groups including the control (5.74). There was a linear tendency of higher lightness (Hunter L* value) numerically for chicks fasted for longer periods. The highest coefficient of determinations of regression models to estimate weight loss as a function of fasting period and body weights were achieved, when the models included both linear and quadratic terms for fasting period, and linear term for both 1.5 ($R^2=0.76$) and 2.5 kg ($R^2=0.78$) body weight groups. Given the practical aspect, approximately 1.5 kg of body weight is dominant, weight loss could be predicted by the following function; live weight $loss=26.6-0.28{\times}(fasting period)^2+12.34{\times}pasting\;period-0.012{\times}body\;weight$, $R^2=0.76$. Current data implied that the optimum fasting time for pre-slaughter chicks varied depending on slaughter weight; 6 and 9-h fasting were recommendable for 2.5 and 1.5 kg chicks, with little effect on objective meat color.

  • The purpose of this study was to examine the effect of exposure to body image in media and bullet screen on weight loss intention by specifically focusing on Bilibili, a video sharing website of China. For the study, a 3 (Social viewing: no bullet screen vs. complimentary bullet screen vs. critical bullet screen) x 2 (Body image in media: ideal vs. realistic) between-subjects factorial design was conducted. A total of 310 Chinese women in their 20s were recruited to participate in an experimental survey. The main results showed that viewing the ideal body image with the complimentary bullet screen and realistic body image with the critical bullet screen strengthened the participants' intention on weight loss. Finally, the interaction effect of social viewing and the types of bullet screen were examined. The higher weight-loss intention was revealed when social viewing was conducted with the complimentary bullet screen of the ideal image. The results of this study can enhance the understanding of the bullet screen as a type of social viewing and its effect on user behavior intention.

  • The purpose of this study is to verify the effect of cellulase treatment on crease resistance of cotton. Cotton fabrics was treated with cellulase under different concentration at $50^{\circ}C$ for 40 min. Also to compare the effect of DMDHEU treatment, DMDHEU treatment was conducted before and after cellulase treatment, also with cellulase. Weight loss, crease resistance and tentile strength of each samples were measured and compared. Maximum weight loss showed at 1g/l con. with 40 min. treatment. Cellulase enzyme treatment was more effective than DMDHEU in the crease resistance and tensile strength. Crease resistant of cotton which treated under different condition with cellulase and DMDHEU showed in the order of cellulase+DMDHEU> cellulase> DMDHEU treatment. Also, tensile strength showed in the order of cellulase> cellulase+DMDHEU> DMDHEU. Among those treatment conditions, condition which treated with cellulase considered more effective to increase crease resistance while keeping tensile strength too.

  • Background: Mahuang (Ephedra sinica STAPF) is well known as an herbal medicine and has been widely used to reduce body weight and increase athletic ability. However, as a result of reporting many cases of adverse effects on the cardiovascular system, use of dietary supplements containing ephedra was prohibited by the FDA. Objectives : The object of this study was to find the effectiveness of ephedra on weight loss without severe adverse effect. Methods : 16 healthy volunteers consisting of an ephedra group (N=8) and a placebo group (N=8) were investigated. Study form was a randomized, controlled, double-blind clinical trial. The ephedra group took 12g of ephedra while the placebo group took 12g of glutinous rice powder. Both groups were measured with BCA (body composition analysis) on weight loss and with HRV (heart rate variability) on its adverse effect before and after medication. Results : The following results were obtained after taking 12g of ephedra for 14 days. In the ephedra group, body weight reduced significantly. In the placebo group, there were no significant differences of body weight between before and after placebo treatment. There was a slight increase of heart beat rate and deactivation of cardiac activity. Parasympathetic nerves were deactivated, but balances of autonomic nervous system were well maintained. Conclusions : The results suggest that ephedra in healthy adults tends to reduce body weight and deactivation of autonomic nervous system and cardiac activity.

  • MDABM and MDAEW, as a accelerating weight loss agents, were prepared by adding water to myristyldimethylbenzylammonium bromide(MDAB) and myristyldimethylethylammonium ethyl sulfate (MDAE) synthesized. As a result of weight loss finishing of the MDABW and MDAEW with NaOH on PET fiber, the ratio of weight loss of MDABW was very larger than that of MDAEW. This result showed that quaternary ammonium bromide had higher weight loss effect than quaternary ammonium sulfate, and the ratio of weight loss was greatly varied with the kind of quaternary ammonium salts used. In these conditions, proper treatment concentration, treatment time, and treatment bath ratio were about 8g/l, $6O{\sim}90min$, and $40:1{\sim}50:1$, respectively.

  • Weight loss experiments have been performed for unidirectional carbon fiber/epoxy laminates under both isothermal and cyclic thermal conditions. It was found that weight losses were the result of both specimen-geometry dependent oxidative degradation and volumetric geometry dependent thermal degradation. Thermal degradation was found to play a major role in the overall weight loss process, and photomicrographs of cross-sectioned, aged specimens confirmed this fact. A method to predict the effect of isothermal environment on the weight loss was introduced and found to be in good agreement with experimental data at temperatures near Tg (glass transition temperature).

  • Dietary therapy is one of the most important treatments for obesity. In general, it is difficult to maintain the recommended diet for weight control for a long time; therefore, it is difficult to achieve weight loss or maintain weight. Intermittent fasting has recently become one of the most popular diets for weight loss. Intermittent fasting is a strategy of repeating intermittent energy restriction and eating, unlike conventional diets of continuous calorie restriction. Studies on intermittent fasting have shown positive results not only in terms of weight loss but also improvement in metabolic indicators, such as glucose control and reduction of blood pressure. Therefore, it is important to maintain a long-term dietary strategy to prevent weight loss in obese individuals. The effect on weight loss was similar to that of an existing continuous energy-restricted diet. However, long term studies and safety data are still lacking, and large-scale studies with various populations are needed. If more evidence is secured for various individuals, it can be expected that intermittent fasting, including time-restricted eating, will be applied clinically in the future.

  • The purpose of this study was to elucidate the effect of weight loss of polyethylene terephthalate(PET) fabrics on the mechanical properties such as bending and shear. In order to compare the effect of treatment machine on the mechanical properies of treated PET fabrics, PET fabrics were hydrolyzed with NaOH aqueous solution using Tank machine and Liquor flow machine, respectively. The results were as follows : 1. The bending rigidity and shear stiffness of hydrolyzed PET fabric decreased markedly up to about 10% weight loss regardless of treatment machines. At the above 10% weight loss, the variation of these properties is nearly unchanged. In addition, the bending hysteresis and shear hysteresis also showed similar trend. 2. Weft density change of PET fabrics treated with Liquor flow machine decreased by 1pick/inch. It is assumed that this is attributed to the tension during the treatment of Liquor flow machine. On the other hand, the weft density change of PET fabrics treated with Tank machine is scarcely influeneced by the weight loss. While warp density of PET fabrics treated with Liquor flow machine had no change with weight loss, warp density of PET fabrics treated with Tank machine decreased by 6pick/inch due to the tension. 3. The bending rigidity and shear stiffness of PET fabrics hydrolyzed with liquor flow machine slightly higher than with Tank m/c at the above 10% weight loss. It is assumed that this is caused by the increasement of the crossing pressure of warp and weft yarn and contact points of filaments in the yarns. Also, the bending and shear hysteresis of PET fabrics treated with Tank machine were higher than that of liquor flow machine.
