This study proposes the suggested amount of clothing (SAC) and examines the preferred amount of clothing (PAC) for thermal comfort in mild cold conditions. Six male and nine female college students were systematically exposed to mild cold conditions by reducing the amount of clothing (Step I, 1.2clo ${\rightarrow}$ Step II, 1.0clo ${\rightarrow}$ Step III, 0.8clo ${\rightarrow}$ Step IV, 0.7clo). The subjects were then asked to adjust the amount of clothing to attain overall thermal comfort until they maintained thermal comfort for 10 minutes without changing the amount of clothing (Step V). The experiment was carried out in a climatic chamber at $19.5^{\circ}C$, 50%R.H. Body composition was measured and individual cold climate adaptability was surveyed before starting the experiment. Rectal temperature ($T^{re}$), skin temperature ($T_{sk}$), and oxygen consumption ($\dot{V}O_2$) were measured and the overall thermal sensation was voted in each step. PAC was obtained from the garments weight selected by each subject in Step V. SAC was proposed based on the change of oxygen consumption (${\Delta}\dot{V}O_2$). As a result, males showed higher $\bar{T}_{sk}$ and greater $O_2$ than females (p<.01). SAC obtained from $\dot{V}O_2$ were 652.0 (SE 3.9) g/$m^2$ for males and 766.0 (SE 2.5) g/$m^2$ for females and it was significantly different between groups (p<.01). PAC of males and females were 1.6 and 1.5 times heavier than SAC. In conclusion, females were more sensitive to the cold stress and recommended larger amount of clothing than males.

This study analyzed the perception types of women over the age of 60 in regards to attitude and the effect of wearing brassiere. In addition, it was also to provide the basic data demand for the development of a brassiere for elderly women. Q methodology was used for this study. Analyze the data using the QUANL pc program. Type 1 was the nipple cover non-preferred type. Type 1 thought brassiere has uplifting effect, but is uncomfortable and only worn when going out. Type 2 was a function-oriented preference type. They wore a brassiere for beauty and psychological satisfaction. The brassiere push-up the breast and enhanced volume. Type 3 was the pursuit of vibration reducing and beauty type. The brassiere reduced breast vibration and kept armpits comfortable. The brassiere was worn for beauty. In the future, the actual development of brassieres for elderly women should be investigated for wearing sensation and satisfaction.

The purpose of this study is to experimentally analyze the relationship between structural characteristics of cotton fabrics and their cool-and-warm felling in order to develop more comfortable fabrics. Comfort in textile products has been emphasized as consumers preferred performance to fashion of clothing. Thermal comfort of clothing is a basic parameter of the comfort sensation which is usually represented by the cool-and-warm feeling felt by human skin. Cloo-and-warm feeling is perceived by the heat flux which transfers heat energy stored in an object to skin. We feel warm (cool) if the temperature of nerve extremity in skin ascends (descends). As cool-and-warm feeling determines the comfort sensation of clothing, it is important to develop new comfort fabrics. Although considerable works have been made on the body, clothing, and environment, there has been no research study on the structural characteristics of fabrics and their cool and warm feeling. Cool-and-warm feeling is closely related to the transient heat transfer property. This research study used the cotton fabrics manufactured in Korea as sample and measured $q_{max}$ value with thermal property measuring instrument (Thermo-Labo II type). $q_{max}$ values estimated by polynomial regression equation were compared with those observed in this study. This study also identified the structural parameters of cotton fabrics for a specific range of $q_{max}$ values. The findings of this study can be summarized as follows: 1) As the thickness, porosity and air permeability of cotton fabrics increase, $q_{max}$ value decreases. 2) As the fabric count and over factor of cotton fabrics increase, $q_{max}$ value also increases. 3) $q_{max}$ values have been estimated by simple and polynomial regression equations developed in this study. Regression curves which have been plotted by polynomial regression equations also provided with the range of structural parameters for a specific range of $q_{max}$ values of cotton fabrics. This study would be significant in that it has identified the structural Parameters for the cool-and-warm feeling of cotton fabric at $65\%$ relative humidity.

The purpose of this research was to investigate the property of sensibility of silk fabrics by the linen-like finishing-used polyurethane resin. Subjective evaluations of preference and related sensory descriptors were estimated. Also, related physical and psychological variables were measured. And their correlations were investigated. The value of EM, WT, WC, MIU, and qmax of silk fabrics treated with polyurethane resin decreased and LT, B, 2HB, G, 2HG, 2HG5, and SMD increased. Physical variables which affected on the preference of summer fabrics are B, 2HB, G, 2HG5, qmax, MIU and LT. It was confirmed that silk fabrics treated with polyurethane resin were preferred as a summer fabric. Individual sensibilities that had effects on the preference of summer fabrics were softness including rough and cold. The intensities of weight value on sensory descriptors, which were related with the preference in summer environments, were in following orders: cold, rough, slippery, flexible, stiff and damp. There was no relationship between the subjective evaluation of preference and related sensory descriptors on the fabric and comfort sensation of fabric was derived from psychological variables

The research is committed to inquire about the attributes of color schemes and their image, and the results are as follows : One, the preference of ranges of neon colors was explicit, and the frequency of use of neon colors distinctively diverged season by season. Two, it was observed that, with neon colors, an achromatic color scheme was a more preferred arrangement. As for chromatic colors, neutral and mid-tone natural colors were more favored since they did not tarnish the properties of neon colors and, yet, more effective exhibiting images in diversity and variety. Three, the neon color fashion generally displayed a dual image: its original classification embellished with neon colors rendering the image of powerful and futuristic sensation. Having been around since the early 2000's, the frequency and range of use of neon colors have been increasing rapidly mostly by the sports, leisure and related industries. Regardless of the fact, neon colors will be rediscovered with a variety of color schemes and expand their application.

To identify optimized thermal properties of mold brassiere cup for improved thermal comfort during summer, we compared the thermal resistance and the water vapor permeability of Polyurethane (PU) foam, 3D spacer fabric and the two combined materials of the PU foam and the 3D spacer fabric. Four experimental mold brassieres were made of the materials for wearing test. Six women in their twenties evaluated the wearing sensation in the hot and humid environment. The changes in microclimate temperature and humidity while wearing test brassiere cups were measured. Results indicate that thermal resistance increased as more PU foam were combined, while the water vapor permeability was higher as the content of the 3D spacer fabric increased at thickness of 18mm and over. However, in the wear test, the PU foam brassiere was the most preferred in all ambient conditions due to its soft, flexible and smooth texture, despite its high thermal resistance and low water vapor permeability. This indicates that the textures of mold foams are more dominant properties than thermal properties for mold foams in determining the wear comfort of mold brassieres.

Although innate color preference of motile organisms may provide clues to behavioral biases, it has remained a longstanding question. In this study, we investigated innate color preference of zebrafish larvae. A cross maze with different color sleeves around each arm was used for the color preference test (R; red, G; green, B; blue, Y; yellow). The findings showed that 5 dpf zebrafish larvae preferred blue over other colors (B > R > G > Y). To study innate color recognition further, tyrosinase mutants were generated using CRISPR/Cas9 system. As a model for oculocutaneous albinism (OCA) and color vision impairment, tyrosinase mutants demonstrated diminished color sensation, indicated mainly by hypopigmentation of the retinal pigment epithelium (RPE). Due to its relative simplicity and ease, color preference screening using zebrafish larvae is suitable for high-throughput screening applications. This system may potentially be applied to the analysis of drug effects on larval behavior or the detection of sensory deficits in neurological disorder models, such as autism-related disorders, using mutant larvae generated by the CRISPR/Cas9 technique.

In this study, girdle wearing was surveyed on the female college students in Seoul and Seoul satellite cities. Data were collected by convenient sampling method, and sample size was 252 subjects in 18 to 29 years. Questionnaire was composed of 5 parts: experience of girdle wearing, the preference of girdle type, degree of dissatisfaction/discomfort in wearing girdle, wear sensation evaluation of girdle fabrics, including demographic and anthropometric data. The results of surveys are as follows: Experience of girdle wearing (season of wearing girdle, main intention of wearing girdle, frequency of wearing, body part to want to be shaped by girdle) was examined. Especially body parts to be shaped by girdle were in order of abdomen > hip > thigh > waist-hip sideline. Therefore, it would be considered that female college students want to care about the shape of abdomen or hip. The long leg panty type was most preferred among the girdle types. The reason of preference of long leg panty type was cost > easiness of putting on-and-off > shaping many body parts at once. For dissatisfaction/discomfort in wearing the commercial girdles, it showed in order of poor ventilation at sweating > static electricity with outer garment > difficult breathing due to pressure > deformation after laundering.

As for the purposes of the research: First, on the wearers of snowboard wear on the market, I intend to investigate contents related with purchase, price, brand, style, etc., and grasp requirements and complaints. Second, I intend to know the evaluations of users according to itemized questions on the snowboard wear on the market. Third, I like to provide basic materials by investigating itemized requirements for the development of snowboard wear. On the male & female snowboarders on a skiing ground, I carried out a preliminary investigation in December, 2001, and a main investigation from January to February, 2002. The results are as follows: 1. Many of them purchased imported quality goods, and the rate purchase was high between 20～25 year. Loose two-piece suits of different colors were preferred. The most uncomfortable part proved to be a neck part. 2. The degree of general satisfaction with the snowboard wear on the market was 4.60. And in terms of itemized evaluation, dissatisfaction was found in Clothing construction, facility of laundry and handling, price and brand rather than in style, fiber composition and tactile sensation. 3. In the investigation of the requirements in case of snowboard wear development, the most common requirement was the facility of action. I believe this should be met by study on the choice of pertinent margin and the pattern development.

This study investigates sound, scenery, and soundscape preferences, which are sensory factors that users feel in a healing forest, comparing the difference in recovery by the soundscape. In the barrier-free, wooden walking path of the National Daegwallyeong Healing Forest, a survey site with five different conditions was selected. Users prefer water sounds the most and places with open views for scenery. For the complex sensation of soundscapes, the most preferred is a space where water sounds can be heard, and either a waterfall or an open view can be seen. A profile of mood states test was use to compare users' psychological recovery by the soundscape. It was found that users felt the most positive mood with water sounds and open views. In addition, users' preference for artificial sounds, scenery, and soundscape was the lowest. In the mood state test, it was found that the artificial soundscape incited the most negative emotions.
