This study is to construe the spatio-temporal characteristics of temperature in cities and the changes of climatical regions by analyzing a climate change in Korea peninsular. We used daily mean air temperature data which were collected in South and North climate stations for the past 34 years from 1974 to 2007. We created temperature maps of 500m resolution with Inverse Distance Weight in application with adiabatic lapse rate per month in linear relation with height and temperature. In the urbanization area, the data analyzed population in comparison with temperature changes by the year. The south climate region in Korea by the Warmth index was expanded to the middle climate region by the latitude after 1990s. A rise of mean temperature was $0.5{\sim}1.2^{\circ}C$ in urban areas such as Seoul, metropolitan and cities which had a rapid urbanization and industrialization with the population increase between 1980s and 1990s. In case of North Korea, cities such as Pyeongyang, Anju, Gaecheon, and Hesan had the same pattern.

Baeja(背子), which was excavated from the tomb of Sim, Su-ryun(沈秀崙, 1534-1589), a civil official, has a distinctive pattern. Two rectangles are connected by button knots on both shoulders and below the armpits, and surround the front and back of the upper body. Also, the back is shorter than the front, while the center-front is not opened. It also has a round neckline without a collar. Jeojuji(楮注紙), which is a traditional Korean paper made from mulberry bark, is put between the outer shell and lining of this clothing as an interlining. The purpose of this study is to perform a morphological feature analysis of the Baeja to examine its characteristics and name, and clothes with similar features, attire relic, pictorial and ceramic materials as well as precedent studies were used in the analysis. The Baeja, which was excavated from the tomb of Sim, Su-ryun, has the same pattern as Yangdang(裲檔), which was worn in the ancient northern region and China. Its composition and the way it was worn are very simple. Also, the shorter back length can be used as evidence that it was worn as everyday outer clothing, and not in a ceremony. Jeojuji, used as an interlining, made it easy to sew and maintain attire pattern and played a role of maintaining warmth. Therefore, this Baeja is presumed to be an outer clothing simply worn in the everyday life for convenience and warmth. In regards to its morphological feature, it was most likely a Yangdang in Joseon Dynasty.

The thermal properies of the pure linen fabrics available in the market and linen blended woven fabrics were measured at the moisture content of 0%, 20%, 40% and 60% using KES-F7 system (Thermo Iabo II type). The experimental properties were statistically analyzed by the rate of water absorbent. The main results were as follows; There is a positive correlation between the thermal insulation value (TIV) and thickness of pure linen fabrics and linen blended woven fabrics by water absorption. Whereas an negative correlation exists between the TIV and cover factor. There is a high positive correlation among the thermal conductivity (k), thickness and weight of pure linen fabrics and linen blended woven fabrics by water absorption. Wherase a high negative correlation exist between the k and air' permeability (Ap). There is a high positive correlation between the feeling of warmth/coldness and bulk density of pure linen and linen blended woven fabrics by water absorption. Wherase a high negative correlation exists between the feeling of warmth/coldness and porosity. There is a negative correlation between TIV and $q_{max}$ of pure linen fabrics and linen blended woven fabrics. The higher the rate of water absorbent, the lower the TIV. This means that TIV decreases by water absorption. As for the thermal property by rate of water absorbent $q_{max}$ and k increase by water absorption and reach max-value at 60% rate of water absorbent. The TIV decreases by water absorption and has +value at 0% rate of water absorbent, whereas it has -value with a feeling of coldness at 20%, 40%. and 60% rate of water absorbent.

This paper investigated wear comfort property of heat storage knitted fabrics for high emotional garment. For this purpose, ZrC imbedded PET knitted fabric was prepared and various physical properties such as thermal, wicking and drying characteristics were measured. In addition, far-infrared emission characteristics of ZrC imbedded PET was analysed and tactile hand property and dye affinity of ZrC imbedded knitted fabric were also studied in comparison with regular and other commercial heat storage PET knitted fabrics. It was observed that Zr imbedded amount in the yarn was 19.29% by ingredient analysis and far-infrared emission energy was $3.65{\times}10^2W/m^2$, emissivity was 0.906 at the range of wavelength $6{\sim}20{\mu}m$. It was found that maximum heat flow (Qmax) of ZrC imbedded PET knitted fabric was lower than that of regular PET one and warmth keepability rate was higher than that of regular PET one, which means ZrC imbedded PET have heat storage property. Drying property of ZrC imbedded knitted fabric was better than that of regular PET one due to heat by far-infrared emitted from ZrC in the core of filament. It revealed that wicking property of the ZrC imbedded fabric was not influenced by far-infrared emission, but affected by fibre physical properties. Tactile hand property of ZrC imbedded knitted fabric was not influenced by imbedding ZrC in the filament but affected preferably by structure of knitted fabric. Dye affinity of ZrC imbedded PET knitted fabric was less influenced by dyeing temperature and time than regular PET knitted one.

This article aims to determine the interrelation among exfoliation strength, the repeated laundry number, the coefficient of friction and the cover factor about the fusible interlining produced by using different amount resin. The practicality of stiffness and warmth of the fusible interling were examined. The results are summarized as follows: 1) As a factor that affecting the exfoliation strength of fusible interlining, the coefficient of friction and the cover factor about the fusible interlining produced by using different amount resin. (2) Regardless of the weight of the resin, the exfoliation strength of fusible interlining declined gradually as the repeated laundry number increased. This tendency arises much more in the case of the filament yarn fabric than in that of the spun yarn fabric. The stability of the exfoliation strength was better, regardless of the increase of the repeated laundry number, when the weight of the weight of the resin was 10 g/$m^2$. (3) The spun yarn fabric, which has more fuzz than the filament yarn fabric, is more suitable for the fabric of fusible interlining. The smaller the cover factor difference between the face cloth and the interlining cloth, the stronger the exfoliation strength. (4) When the stability of the shape is a necessary factor in the consumption of the fusible interlining, a resin weight of 20 g/$m^2$ is the most suitable; however when stiffness and warmth are necessary factors, a resin weight of 10 g/$m^2$ is the most suitable.

Consumer and property evaluation of wetsuit materials were conducted to obtain useful data for developing competitive products that meet consumer expectations and improving industrial competitiveness. Data were collected through online surveys of 213 domestic consumers who have experienced wearing wetsuit among marine leisure activities. Five types of commercial wet suit materials by brand and four types of commercial wet suit materials with the same quality by thickness were collected. Then, their physical properties, salt water resistance and thermal insulation rate were evaluated and compared. As a result, the most commonly used wetsuit material is 3 to 5 mm thick, and the basic jersey material is bonded on both sides. As a processing for imparting functionality, processing for improving warmth and reducing surface resistance are most frequently used. Consumers often feel uncomfortable when wearing a wetsuit, such as wearing comfort, weight, ease of movement, stretchability, and clothing pressure, which are different from those of casual wear. Also, mechanical strength and warmth were considered to be the most important criteria for selection of wetsuit material for purchase or rental. The mechanical properties of brand A and B were better than those of brand C, D, and E. Resilience and thermal shrinkage were better in brand C, D, and E. On the other hand, there was no significant difference in the physical properties due to the difference in thickness of the material at the same quality. Also, it was found that the thicker the material, the more stable it is in the heat. Brand A and B had superior salt water resistance than brand C, D, and E. In the thermal insulation test, brand A and B showed better insulation characteristics than brand C, D, and E, but the types of bonded fabric and surface finishing of materials were thought to have affected. In comparison of the thickness, the thicker the materials, the better the salt resistance and the thermal insulation.

A smiling face usually has a positive effect on interpersonal relationships by delivering a warm impression. However, the stereotype content model and compensation effect between warmth and competence suggested that warmth perceptions caused by a smiling face could influence competence perceptions negatively. This study examined the negative impact of the advertising endorser's smile on purchase intention in an expensive product category by adopting the self-construal level. The study results showed that consumers with independent-self construal (vs. interdependent self-construal) showed a lower purchase intention when exposed to an ad containing an endorser's smile. In comparison, consumers with interdependent-self construal (vs. independent self-construal) showed a lower purchase intention when exposed to an ad without an endorser's smile. Thus, this study demonstrated a moderating role of self-construal in the relationship between advertising endorser's smile and purchase intention. These findings provide valuable theoretical and practical implications for effective advertising strategies in the expensive product category.

The purpose of this study is to find out the factors that explain the sense of touch and preference of man-made leather. Date base of descriptors for man-made leather was collected by interviewing 50 consumers, 33 different kinds of commercial man-made leathers(synthetic leather and artificial leather) were assessed subjectively by 605 consumers using the 9-point scale of 34 pairs of bipolar descriptors based on the data base. Subjective ratings were analyzed by principal axis factoring with varimax rota-tion. The sense of touch of man-made leather is explained by five factors ; surface property stretchiness thickness& weight thermal property(warmth & coolness) and moisture property (sticky & clingy). The difference in the sense of touch of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leather is explained by three factors ; surface property stretchiness and quality. Higher preference is found in man-mad leather of better quality touch and softness.

This study investigated child's self-esteem by the mediational role of mother's parenting self-efficacy and its relations to perceived social support, parenting behavior, and stress, and to child's temperament and gender. Participants were 403 Korean children(188 boys, 215 girls) and their mothers living in Seoul. Structural equation modeling for boys and girls and their mothers indicated that parenting self-efficacy mediated the relation between social support and parenting behaviors including Warmth-Acceptance and Rejection-Restriction. In these models, parenting self-efficacy related to child's self-esteem through parenting behavior. Child's temperament related to self-esteem directly in three parenting behavior models. In Permissiveness-Nonintervention, parenting self-efficacy mediated between social support and self-esteem in both boy's and girl's models, between child's temperament and self-esteem in only boy's model.
