To study the visual evaluation on the effect of ruffle's gather, the aesthetic evaluation on the gather's measurements and the image evaluation were performed. Evaluated fabrics were cotton, wool ani synthetic fiber, and 3 kinds of thickness for each fabric were selected. In order to seek for aesthetic gather's measurements, we performed the sensory test by the Rank Method on 5 kinds of gather's measurements(I.5 times, 1. 8times, 2times, 2.5 times, 3 times). For the image evaluation on the effect of the gather, we performed the sensory test by the Semantic Differential Method on the gather's measurements were got high score in the sensory test of the gather's measurements and analyzed by means of a Factor Analysis. The results were as follows. 1. Except 2 times of fabric $A_1$(thin cotton), the aesthetic gather's measurements of the ruffle were evaluted 2.5 times in cotton and synthetic fiber, and 2 times in wool. Generally the aesthetic gather's measurements of the ruffle were 2$\~$2.5 times. 2. The image characteristics of the ruffle were established the characteristics of the fabrics as factor 1, the characteristics of the atomosphere as factor 2 and the characteristics of the drape as factor 3. Therefore, we must consider the characteristics of the fabric, the atomosphere and the drape of the ruffle in production of the ruffle.

Authors have studied the adsorption of anionic surfactant from detergent solutions on cotton fabric during washing process and have measured the concentration of the residual surfactant in rinsing solution. The relations with temperature and pre-soaking time to rinsing process have been studied. The adsorption of sodium dodecylbenzene sulfonate by various textile fibers has also been investigated. The results of this study are; 1. Three times rinsing is sufficient as, without pre-soaking, the concentration of the surfactant on fabric is stable from that time on. 2. The rinsing efficiency increases with temperature; at $25^{\circ}C$, $40^{\circ}C$, and $55^{\circ}C$, the concentrations of surfactant on the fabric after-rinsing are 68, 59, 51 mg/100 g of fiber respectively. 3. The longer the pre-soaking time, the lower the rinsing efficiency is; the 4hrs presoaked fabric shows increased surfactant concentration than the one without-soaking. And the increment is 35.8%. 4. The adsorption of sodium dodecylbenzene sulfonate on fabrics differs greatly with the chemical nature of the fiber; wool, silk and nylon which are thought to be ionic-adsorbants shows greater adsorption. 5. The adsorption of surfactant is more affected by the ionic character than the physical one, and the one with higher crystallinity such as cotton and polyester shows lower value than rayon or acetate.

In recent years, the home meal replacement (HMR) market has expanded and the consumption of ready-to-heat (RTH) rice has significantly increased. In this study, RTH rice products containing seaweed were prepared with different types of grain: white rice, a mixture of white rice and barley, barley, and mixed grains. The control was a commercial RTH white rice without seaweed. The proximate components, total dietary fiber, in vitro starch digestibility, and antioxidant activity were compared. The ash content of the RTH seaweed rice was higher than that of the control (P<0.05). The total dietary fiber of the RTH seaweed rice was in the range of 1.03-6.57%, which directly impacted the in vitro starch digestibility. The in vitro antioxidant activity including total phenolic content, reducing power, DPPH (2,2-diphenyl-1-picryl-hydrazyl) and ABTS⁺ (2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid) radical scavenging activity of the seaweed rice with barley and the white rice/barley mixture was greater than that of the other rice products (P<0.05). These results indicate that the in vitro digestibility and antioxidant activity of the HMR RTH seaweed rice were greater than those of the control. In addition, when the RTH seaweed rice was prepared with barley, the functional activity improved.

We need to diversify the colors by natural dyeing for promotion and extention of the natural dyes market, because natural dyestuffs have the limitation the number of the colors to express, compare to synthetic dyestuffs. It was investigated that wool and silk fabrics could be dyed to green colors using natural mugwort and indigo as one of color diversification, in order to express green color that is difficult to be shown by natural dyeing. The mugwort dyebath was prepared to concentration of $25{\sim}100g/l$ using dried mugwort plant and indigo dyebath was prepared to concentration of $5{\sim}20g/l$ using natural indigo powder. Wool fabrics and silk fabrics were dyed to green(GY, G, BG in Munsell color wheel) by two batch methods using the mugwort and indigo dyebaths. the mugwort dyeing was applied at $80^{\circ}C$ for 20minutes and indigo dyeing applied for $5{\sim}7$ minutes in room temperature. The colorfastness to drycleaning and abrasion of the dyed fabrics were shown good as grade 4-5 or 5.

This study investigated whether social and psychological factors were related to nutritional status of the elderly. Food habits, social contacts and psychological the test score were collected from 86 institutionalized elderly women aged 65-96 in Chon-buk area. Social health status was measured by score of social contacts with others. Depression, self-esteem and locus of control were measured to evaluate psychological health status by using Zung DSI(Depression Status Intentory), Rosenberg SES(Self-esteem scale) and Rotter's vs external control, respectively. Social contacts of the total subjects were lowered, and in the group of over 85, contacts with relatives were significantly decreased compare to under 85 years of age groups. Psychological health status such as depression and self-esteem were also lowered, but locus of control showed internal control that indicates positive attitude to eating behavior. Most of the nutrients intake were positively correlated to self-esteem scores(p<0.05), but not to nutritional risk index score. Intake of vitamin C was related to social health status as well as psychological health status. Increasing the number of contact with relatives, intakes of carbohydrates, fiber, vit B1, vit C, Ca and P were elevated(p<0.05). As the score of self-esteem increased, intakes of fiber, Fe, vit B1, niacin, vit C, and vit A were increased. It is suggested that social activity and health education programs will be needed to improve the nutritional status of the institutionalized elderly.

The purpose of this study was to examine the effect of temple food intake on health improvement. The survey was conducted from September to October 2013. The subjects in this study were 46 adults who participated in short-term 'Temple Stay' program. Every meal was prepared according to prearranged temple food menu, and it was provided to subjects for 4 weeks. Dietary intake, anthropometric measurements and biochemical parameter were measured and nutritional & health status were analyzed to find the effect of the program. Nutrients content of the temple food was sufficient to dietary reference intake while content of fat, fiber, vitamin A and calcium from the meal was significantly higher than the subjects' usual diet. Mean body weight, BMI and blood pressure (systolic and diastolic) related with obesity and hypertension decreased after the program. The index referring to liver function and cardiovascular disease risk such as serum ALT, ${\gamma}$-GTP, TG and LDL decreased while HDL increased thereby showing positive effect. The above results anticipate that temple foods with an affirmative effect in improving health status have a potential benefit that can be applied to general food service. Further detailed study might provide information in developing healthy diet for a corresponding clinical problem.

This study is to furnish basic data for making appropriate and comfortable pillow. This research was carried out in reference to 260 males and 339 females whose ages are above 20 in Daegu, from Aug. 1. 1984 to Oct. 15. 1984. RESULTS : 1. In the shape of pillow, the western style is more used than Korean style. 2. The mean size, 50.9$\times$29.1 cm, of pillows is too small for the preceding studies of which, the most comfortable size is 65$\times$45 cm. 3. The mean height, 10.1 cm, of pillows is much higher than the appropriate height, 5.0$\pm$1cm, in the preceding studies. 4. The mean weight, 1587g, of pillows seems to be too heavy. 5. The most used stuffing of pillows is fascicular fibers, the second chaff, the third husks of buckweat, the fourth sponge, and then feather, 6. Considering of pillow-slip material, 68.8% of pillows consist o synthetic fiber.7. The mean compression rate 14.5% is much lower than the comfortable compression rate 40~50 in the preceding studies. 8. Considering the way obtainment, ready-made articles are more used than the domestic-made articles. 9. The same pillows are used throughout for seasons, and that seems not to be appropriate because climate is changeable according to seasons in our country. 10. The sterilization by sunlight is rarely carried out and that is unhygienic because pillows used to absord much of sweat during using time.

The purpose of this study was to understand the diversity and speciality of Aztec dress which has not been well known, and to overcome ethnocentrism in clothing perceptions. From 15 century to early 16 century, the Aztec empire based on the unique view of the world, most flourished in Mesoamerica. Ritualistic and official side of Aztec life was reflected well on dress. Most Aztec garments consisted of unsewn pieces of cloth, draped on the body as loincloth, mantle and wraparound skirt. Slightly more complicated garments such as women's blouses(huipils) and men's simple jackets were created by sewing together two or more pieces of material. In the sharply stratified world of Aztec, strict sumptuary laws controlled dress. The garments of lower classes were made of maguey or yucca fiber, and only the upper classes were allowed to wear cotton clothing. In addition to material, color, elaborateness and even manner of tieing the mantle were carefully controlled by government edict. As the Aztec empire expanded and became wealthier, the sumptuary laws could not actually dictate what people wore everyday but rather provided a set of rules governing clothing for ceremonial occasions. Aztec's warrior costumes, consisted of headdress, towering back devices, feather garments, were sufficient to suggest the theatrical grandeur of what must have been one of the most magnificiently attired armies ever assembled.

Moisture related properties of fabrics in dynamic modes are considered to be important in the judgement of the subjective comfort characteristics of clothing fabrics. In the current study, an attempt to improve the cobaltous chloride test method was made which has been known as a convenient screening test for dynamic surface wetness. The color changes of cobaltous chloride treated fabrics on the simulated sweating skin were calibrated against standard color strips. The standard color strips were made of all typs of test fabrics and installed inside of the test tubes containing a series of saturated salt solutions, which gives more quantitative informations on dynamic moisture transfer Influences of fiber types and finishes on dynamic moisture transfer in textiles were studied using a single layer of fabric samples. Fiber types included $100\%$ cotton, C/P 50/50, C/P 35/65. Durable press and soil release finished cotton and C/P 50/50 fabrics were also included. There were significant fiber effects on the dynamic moisture transfer. The order of time taken to reach to the specified $\%$ RH was C/P 35/65$100\%$ cotton fabrics. It was possible to detect significant finish effects by increasing the concentrations of cobaltous chloride solutions. The order of time taken to reach to the specified $\%$ R.H was durable press$100\%$ cotton, C/P 50/50, C/P 35/65 and $100\%$ PET were placed at the inner side of the outer layer and tested. It was shown that cobaltous chloride treated $100\%$ cotton fabirc was easier to detect color changes than C/P blend fabic in the double layer experiments. By placing test sample under the cobaltous chloride treated cotton fabrics, it was able to detect the differences among the test samples, some of which were known to be difficult in padding with cobaltous chloride solutions. Besides, the double layer method would provide with the broader application of the cobaltous chloride method in !uture, since it is possible to test the dynamic moisture transfer of clothing as worn.
