Microwaves are high frequency radiation capable of generating very rapid, uniform and efficient heating of textile material. Microwave heated dyeing of polyester fabric was tried with different solvent systems, irradiation time and dye concentration. Microwave fixation methods were used with 100% water,30% urea, EG and DMF, respectively, pad-baths in which the padded fabrics were exposed over a heated or boiling water bath to maintain sufficient moisture content during irradiation. In order to ascertain the relation between the dyeing property of polyester fabric and the microwave irradiation condition caused by microwave heating, the K/S values and fastness properties of dyed fabrics such as light, washing and sublimation fastness were measured.

It is said that the highlights of Naadam festival, the biggest festival of the year in Mongolia, are three athletic contests: wrestling, horse racing, and archery, where contestants display their courage, strength, dexterity, and marksmanship. This paper explores the characteristics of the uniforms worn in such athletic events The findings are as follows. First, wrestlers' costume is completely unique in that it consists of shuudag, snug shorts, zodog, a jacket with sleeves but with no front, a traditional hat, and gutul, traditional boots. The main material used in the costume is several pieces of embroidered red or blue silk. Second, horse riders, usually young children lighter than the adults in weight, wear a bright, colorful, and comfortable uniform of a simple jacket and a pants. Third, archers' mostly put on their traditional costume, deel and hats. The hats are of two kinds: the traditional ones or the European-style ones for men, which were introduced around 1930s.

The situation of wearing of surgery gown and their awareness were surveyed to clinicians and nurses in operation rooms of major university hospitals in the country to develop and manufacture surgery gowns for medical personnels. The survey result was quantified to be used as a base data for design of surgery gowns with freshness and convenience as well as safety to wearers. In the inspection of surgery gowns focused on materials (cotton raw material and disposable nonwoven) and dissatisfaction, there was no significance in the activity and freshness with p-0.745 and p-0.367, respectively, however, there was a significance in safety and management with p-0.011 and 0.049, respectively: disposable nonwoven gown showed higher satisfaction level in safety and management compared to cotton gowns.

This study investigates the behavior of water vapor permeability of a layered system to find out a comfortable combination of a layered system for outdoor activities and examines the water vapor permeability of various types of outdoor clothing fabrics. The layered system includes the base layer such as sportswool and polyester/cotton fabrics, the middle layer such as single and double sided fleece fabrics, and the shell layer such as polyurethane-coated, PTFE-laminated and microfiber fabrics in this experiment. Results show that the layered system was applied, it was working together as a whole having some influence on each other layer, though every layer offered varying degree of water vapor permeability. Water vapor permeability of layered system exactly followed the same trend as the shell layer, which is all vapor permeable water repellent fabrics as a single layer. The rate of water vapor transfer through a layered system is mainly related to the type of vapor permeable water repellent fabrics used for the shell layer.

As in our $20^{th}$ century, the dramatic advance of the science and medical technologies has led the advance of living standards. Even though the elderly people are increasing, the underwear for elderly women is not so various. As getting older, women's body shape is changing. But the most of underwear in the market are designed for the twenties whose body shape and proportion is generally stable. Besides, as the color and material of underwear are designed for young women, the elderly women have a poor choice of the underwear. The results of this study are listed in the following: (a) analyzing the current status of the underwear market for elderly women (b) searching what elderly take inconvenience in underwear, and (c) wearing test for search what elderly take inconvenience in brassier.

In this study, natural substance and mineral materials was used for architectural interior wallpaper. Because natural substance and minerals are environment-friendly material with moisture adsorption and desorption properties. Natural substance and mineral materials was evaluated in moisture adsorption and desorption properties. Also, in the diatomite, the pores were observed on SEM photographs. Thus, it is supposed that moisture adsorption and desorption properties were influenced by the microstructure of the pore. The wallpaper according to the ratio of the mixture was analyzed for physical properties and moisture adsorption & desorption properties. As a result, we developed a wallpaper having excellent hygrothermal performance.

Microcapsules containing 2, 4, 4'-trichloro-2-hydroxydiphenyl ether and perfumes were prepared by the coacervation using poly (vinyl alcohol) and crosslinking agents. Effects of dispersing agents, core materials, agitating speed and crosslinking agents on microcapsule size were investigated. The mean and deviation of microcapsule diameters decreased with increasing agitation speed. The diameters of m;crocapsules decreased with increasing dispering agent concentration at 6, 000 rpm of agitation speed, but it was not changed at 10, 000 rpm. The dispering effect of PVA is better than that of gum arabic. The slight increase in the diameter of microcapsule was observed when the amount of core material was increased. As the amount of crosslinking agent was increased, the diameter of microcapsule was decreased.

The purpose of this study is to investigate the dyeability, antibacterial activity on silk and rayon fabrics dyed with cochineal. The result are as follows; 1. The K/S value of silk fabric was higher than that of rayon fabric. 2. The optimum conditions are mordant concentration $0.5{\sim}1%$, dyeing material concentration 2.0%(o.w.f), dyeing temperature $60^{\circ}C$, PH 3 and dyeing time 30minutes. 3. Pre-mordanting method had higher dyeing absorption than post mordanting method in case of silk and rayon fabrics. 4. The antibacterial activity of dyed silk fabrics were higher than that of dyed rayon fabrics and the antibacterial activity was increased by mordanting. 5. The lightfastness and perspiration fastness of silk fabric were improved but these of rayon were not. Dyeing fastness was improved by Fe mordanting on both fabrics.

Porous carbons have beef used as adsorbents, filters, catalyst supports, etc. due to well-development pore structure. Porous carbons can be prepared by two different activation processes i.e. physical activation by steam or CO$_2$, and chemical activation by KOH, H$_3$PO$_4$ etc. from various raw material. Recently, agricultural wastes such as rice hulls [1], coconut shell [2-31 and straws [4] are growing interest as precursors fur porous carbons due to its easy availability and cheapness. (omitted)

A novel bioabsorbable suture material, poly(glycolide-caprolactone) (PGLCL) monofilament, was prepared by spinning of the PGLCL copolymer. The physical properties, strength retention, biocompatibility, and organism resolvability of the PGLCL monofilament were investigated. The results showed that the knot pull strength of the monofilament was higher than that stated in European Pharmacopoeia. The in vivo retention strength following implantation was 64%, 23%, 7%, and 0% after one, two, three, and four weeks, respectively. Mortality, clinical signs, validation, and sterility tests indicated that all items had passed. Organism resolvability tests showed that the PGLCL monofilament, as a suture, was absorbed within 91 days.
