  • In recent years, research and development has been carried out in order to increase the economical efficiency and stability in terms of efficient use of energy for the heating apparatus. Especially, technology development for high performance and new functional materials is actively being carried out. This paper focuses on the development of exothermic products with excellent energy transfer characteristics. The heating element used for bedding or mattress uses a heating wire. Since the heating wire is thin, the distribution of heat is concentrated only around the heating wire,. In addition, electromagnetic induction is harmful to the human body and energy consumption is high. Therefore, it is aimed to develop a planar heating panel using SiC ceramics which can radiate far-infrared rays and anions to be harmless to the human body, but also has excellent heat conduction to enhance energy efficiency.

  • Gamrosu is a modified fasting therapy beverage (431 kcal/d). A retrospective observational study was conducted to investigate the detoxification feasibility of Gamrosu. Three cases were reviewed which participants have finished the fasting with Garmrosu for 10 consecutive days. Detoxification profiles of Gamrosu were reviewed at pre- and post-fasting sessions. Post-Gamrosu session, -6.3% of average weight, -6.5% of average body fat mass and -6.6% of average muscle mass were reduced with the nutrition indices being improved. The inflammation indices showed the significant diminished profiles. Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners, however, marginal elevation of total bilirubin and mild ketoacidosis were observed. The indices of oxidative stress decreased and those of antioxidative activity increased. The fatigue scale scores indicated lower scores except insomnia symptom. Taken together, detoxification profiles of Gamrosu were sufficiently feasible and the observed findings should be considered for further clinical studies.

  • In manufacturing process of composite cylinders with metal liner, the autofrettage process which induces compressive residual stress on the liner to improve cycling life can be applied. In this study, a finite element analysis technique is presented, which can predict accurately the compressive residual stress on the liner induced by autofrettage and stress behavior after. Material and geometrical non-linearity is considered in the finite element analysis, and the Von-Mises stress of a liner is introduced as a key parameter that determines pressure cycling life of composite cylinders. Presented methodology is verified through fatigue test of liner material and pressure cycling test of composite cylinders.

  • As Kamisipjeondaebotang (KSD) extract is an herbal ingredient, safety is very important due to possible cell poisoning or heavy metal toxicity to organs when administered to humans or animals. Accordingly, this study examined the antioxidant and anti-inflammatory effects of KSD extract to confirm its medicinal safety by using RAW 264.7 cells after heavy metal screening, functional index test of the liver and kidney, and cell survival rate test. Heavy metals were not found in KSD extracts or were less than standard amounts. Liver function indices such as aspartate aminotransferase and alanine aminotransferase revealed low values and kidney function indices such as creatinine and blood urea nitrogen were not significantly different from the normal group. This proved the safety to the human. RAW 264.7 cells showed no poisoning compared to the control group in terms of survival rate. Regarding the antioxidant effect of KSD extract, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazo-line-6-sulphonic acid) radical scavenging activity increased at concentrations over $10{\mu}g/mL$. The anti-inflammatory effect of KSD extract significantly decreased based on the amount of nitric oxide at concentrations of 10 and $100{\mu}g/mL$ compared to the control group. Expression of interleukin (IL)-$1{\beta}$ and IL-6 decreased in a concentration-dependent manner. There was no significant difference in tumor necrosis factor-${\alpha}$ level. Based on the results, KSD can be regarded as a safe antioxidant with anti-inflammatory effects for fracture treatment.

  • We evaluated the bioavailability of a novel organic Ca supplement chelated with milk protein (CaMP) in growing rats and compared it with those of Ca carbonate and Ca citrate. Four-week-old male rats were divided into six groups (n=6/group) and fed AIN-93G-based experimental diets containing three Ca sources, Ca carbonate, Ca citrate, and CaMP at two levels, normal (0.5%, w/w) and high (1.5%, w/w), for 6 weeks. Growth, mineral contents of serum, Ca content and breaking force of femur, and Ca absorption were measured. There were no significant differences in weight gain or food intake, but food efficiency ratio (FER) of CaMP in the high Ca group was higher than those of other groups. Ca and P concentrations in serum were within normal range in all experimental rats. There was no difference in Ca content of the femur among all of the groups. Although there was no statistical significance in bone breaking force of the femur among the groups, the CaMP groups had a higher breaking force compared to other groups. Further, Ca absorption rate significantly increased in the CaMP groups (p<0.05). These results demonstrate that the CaMP supplement did not exhibit any negative effect on growth or Ca metabolism of the rats. Therefore, CaMP can be recommended as a good Ca supplement with regard to bone metabolism and Ca bioavailability.

  • In Japan, a country renowned for her traditional respect for handicraft, superior craft techniques have been transmitted from generation to generation. Modern Japanese textiles reinterprete these traditional techniques in a new light and combine them with modern technology, to make modern Japanese industrial textile both futuristic and traditional simultaneously. This combining of new technology and handicraft serves as a reservoir for a remarkable diversity and originality in the development of new technology and design, and constitutes an important trend in modern industrial textiles. The aim of this study is to investigate the developmental background of Japanese textile industry that championed this trend to make the Japanese development unique in modern textile industries and to consider the concept of modern textiles as well as the structural innovation as represented by this new trend, thus contributing to the development of creative textiles for the present and the future. The findings of this study can be summarized as follows. The combining of new technology and traditional handicraft: 1) was made possible by Japanese consciousness that values traditional culture and by early recognition of advanced textile industry, which awarded new meaning and value to the traditional handicraft leading to an expanded social role for textiles. 2) helped construct a modern concept of textiles by pursuing textile media that are state-of-the-art, aesthetic, and highly sensitive to satisfy the requirements of modern industrial textile such as high quality, high performance, and high sensitivity. 3) enabled new design ideas and creation of new styles by implementing structural innovation in industrial textiles that involved diversification of expression, diversity in materials, and emphasis on texture. In short, by combining new technology and traditional handicraft, Japan came up with a new sense of aesthetics that is highly original and high level and with which the rest of the world can easily sympathize, thereby presenting one of the most important guiding principles for future textiles.
