Objectives : This preliminary study investigated the effect of acupuncture treatment on short-term ketogenic diet-induced weight loss and glucose intolerance in mice. Methods : Six-week old male C57BL/6J mice were randomly assigned to 3 groups: normal, KD, and KD+ACU. All the mice except normal group were fed with ketogenic diet formula for 7 weeks and mice in KD+ACU group received acupuncture treatment three times a week. Body weights were measured three times a week, and glucose level was measured on week 1,3,5, and 7. Ketone level was measured on week 3,5, and 7. Results : Ketogenic diet showed short-term weight loss effect, however, acupuncture treatment did not affect on the weight loss. Ketone level was increased in KD fed mice compared to normal diet fed mice and the level was decreased in KD+ACU group on week 3. However, the change was not significantly different compared to KD group on week 7. Glucose intolerance was improved in KD+ACU group compared to KD group. Conclusions : Acupuncture treatment was effective in relieving glucose intolerance, and the results suggest that combining acupuncture treatment with ketogenic diet may complement each therapeutic intervention by improving glucose intolerance but not effecting on weight loss. This study provides meaningful evidence as a preliminary study of acupuncture treatment on ketogenic diet.

본 연구에서는 열화 온도가 아민 (D-230), 아마이드 (G-5022), 그리고 산무수물 (HN-2200)에 의해 경화된 에폭시 접착제의 질량변화, 유리전이온도 및 모폴로지에 미치는 영향을 고찰하였다. 실험 결과, 3가지 접착제 시편의 질량감소는 열화 온도가 증가함에 따라 증가하였다. 이는 열화 온도가 증가함에 따라 시편의 표면에서 더 많은 열화가 발생하여 시편의 질량이 감소한 것으로 판단된다. DSC 분석결과에 따르면 DGEBA/D-230과 DGEBA/G-5022 시편의 유리전이온도는 열화 온도에 따라 증가하였으며, DGEBA/HN-2200 시편의 유리전이온도는 열화온도 $150^{\circ}C$, 열화 시간 7일 이상에서 일정한 값을 나타내었다. SEM 결과에서 열화 이후의 DGEBA/G-5022 시편의 표면은 DGEBA/D-230 또는 DGEBA/HN-2200 시편보다 거친 모폴로지를 나타내었다. 이 결과는 시편의 질량 변화에서 얻은 결과와 일치하였다.

The purpose of this study was to investigate the effect of alkali treatment on EG solution of polyester/silk union cloth(P/S cloth) . Tensile strength, moisture regain, crease resistance, and reduction ratio of the treated P/S cloth were measured. The results of this study were as follows ： 1) The weight loss of P/S cloth treated with EG solution was three times higher than those of P/S cloth treated with $H_2O$. The weight loss of P/S cloth was increased greatly with increasing concentration of NaOH, temperature, and time. Favorable weight reduction of treating condition could be obtained when lower concentration of NaOH was used with longer time. 2) If it was added $H_2O$ on EG solution, weight loss of polyester increased, while those of silk decreased. In addition, decreasing ratio of tensile strength warp direction (polyester) was lower, while those of weft direction(silk) was higher. 3) Moisture regain of P/S cloth treated with EG solution increased with weight loss up to 10% . Crease resistance of P/S cloth was the highest at weight loss of 10~15%.

The aluminum extruded panel used for a high speed train shows the largest contribution to sound insulation performance of the train body. However, comparing with the flat panel having the same weight, the transmission loss falls sharply in the local resonance frequency band. Such fall of transmission loss can be improved by increasing the damping of local resonance. This study examines the charging effect of an urethane foam on the aluminum extruded panel of a high speed train. We charged the urethane foam with different mass density and in different way in the core part of the extruded panel. We measure the transmission loss and compare the sound insulation performance according to the density and charging method. Finally, Improvement effect of the transmission loss is compared and analysed in aspect of weight increment.

This study was conducted to investigate the influence of addition of cetyl trimethyl ammo­nium bromide (CTAB), and amine [ethylamine (EA) or ethylene diamine (EDA)] to aqueous sodium hydroxide (NaOH) solution on polyester alkaline hydrolysis, The experimental vari­ables such as CTAB concentration, EA or EDA concentration, NaOH concentration, tempera­ture and time were compared, and the changes in physical and chemical properties of alkaline­hydrolyzed PET fabrics depending on their treated conditions were measured, The results are as follows: 1. By adding CTAB and amine in aqueous NaOH solution, increasing effect on weight loss of PET fabrics was obtained in simultaneous addition of CTAB and EDA, but not in CTAB and EA. 2. By adding CTAB & EDA simultaneously, increasing effect on weight loss was obtained regardless of EDA concentration, time and temperature, and it was more effective at lower NaOH concentration. :l. The increase of void space (or irregularly grooved surface), of softness, of wickability, of dyeability on PET fabric, and the decrease of tensile strength, of molecular weight were observed according to the weight loss on the PET fabrics. These changes were equal to all alkaline-hydrolyzed PET fabrics regardless of addition of CTAB and amine. l. There was little changes on crystallinity, thermal behavior when PET fiber was treated with ,aqueous NaOH solution with CTAB and EDA. These results supported that increasing effect on weight loss take place without inducing of fine structural change of PET fibers.

This study initiates from the question of whether current advertising regulations are appropriate to be applied to the market. It confirms the relationship between misleading online advertisements of weight-loss food and consumer damages. This study argues that it is necessary to enforce monitoring and regulating (strengthening monitoring) for situations where misleading advertisements are exposed in the market with subsequent consumer damages. However, deregulation is needed for advertisements exposed in the name of misleading advertisements but with no consumer damages. In conclusion, the regulations of current weight loss foods are properly established $vis-{\grave{a}}-vis$ the market situation. However, misleading advertisements are prevalent for all regulated types: Type I (product quality and effect), Type II (endorsement and warranty), Type III (ways to use and safety), Type IV (comparison and superiority), and Type V (company information). Promotion targeting businesses, market monitoring and control are necessary to ensure that advertising regulations (which have existed only as an institution) can be appropriately applied. It is also confirmed that 'comparison advertising' (applicable to Type IV where consumer damages were not shown compared to other regulations) does not have an actual effect as a consumer protection regulation that should be considered in regulation revisions. Consumers also did not recognize Type III and V in the purchasing stage while consumer damages were demonstrated; consequently, this implies that consumers need to check and become attentive to these types.

Broad, mercerized broad, mercerized twill cotton fabrics and rayon fabric were treated with cellulase for 30~480 minutes at different temperature, concentration, time, and also treating methods such as continuously-treated or repeatedly-treated, and dyed with two direct dyes before or after enzyme treatment. From the experimental result by treating under the various conditions above, it was obtained that the weight loss increased more in thin fabric than thick one. In addition, it was considered that the treatment in 5$0^{\circ}C$ for 240 minutes brought about the ideal weight loss and flexible hand of the specimens. For both broad and mercerized broad, repeated treatment showed more weight loss than continuous. Direct dye on cotton fabric apparently inhibited hydrolysis. Ionic surfactants showed the inhibition effect of the catalytic hydrolysis of enzyme, on the other hand, nonionic surfactant did not.

Alkaline treatment gives Sea-Island type yam to produce microfiber and silk-like touch. But this treatment have some problems in dyeing and finishing process. To solve some problem occurred in dyeing and finishing of polyester fabric, the ultrasonic treatment technique was used recently. This study was carried out to confirm the effect of the ultrasonic treatment on alkaline weight loss finishing of polyester fiber under general alkaline treatment conditions; NaOH concentration 2, 3, 4, and 5％, treatment time 5, 10, 15, and 20 minutes, treatment temperature 70, 80, 90, and 99'E, respectively. On the other hand, the three way lay out method was used to test of significant obtained data from alkaline treatment. It was found that weight loss increased with increasing the NaOH concentration, temperature, and time. Also, in case of PET/Co-PET fabrics by ultrasonic, weight loss and dissolution of microfiber were superior to PET/Co-PET fabrics without ultrasonic. Tensile strength and modulus decreased with increasing NaOH concentrations and hydrolysis time. Therefore, the effect of alkali hydrolysis by ultrasonic application was better than that of the conventional method.
