This study examines the difference of surface properties according to napping characteristic of artificial suedes, measuring surface structure observation, the contact/non-contact method roughness, warm-cool feeling of touch, and subjective hand evaluation. Surface and cross-section observations showed a discernible difference in fineness, curl, length, mount of napping, and covering power of base fabric. The surface properties of artificial suede evaluated by KES-FB4 showed that the shorter napping length the more smooth surface and the roughness increased reciprocally with friction resistance and surface contour when the nap length reaches a high level. The surface roughness measuring system applied a laser displacement sensor by a non-contact method to assess napping characteristic and the base fabric and napping height. Surface roughness decreased when napping was uniformly covered with base fabric; however, the surface roughness increased specifically with the uneven covering power of the base fabric. For qmax of the suedes, those that had short and smaller amounts of napping increased; however, the napping of length and amount at some stage generated a low qmax value. The warm sensation in all suedes were strongly perceived, but the cool sensation of the perception was lower in the subjective evaluation. Smoothness and softness were perceived when the suede has a long and large amount napping; however, smoothness and hardness were perceived when the suede was short and with the uneven covering power.

The purpose of this study was to determine conditions of dining behaviors, sleep patterns, rates of obesity and intake of snacks and self-purchased snacks deriving from the lack of sleep in academic high school students. The anthropometric characteristics, height and weight (p<0.05), and the distribution of obesity index (p<0.001) showed significant differences between males and females. Dining scores for both male and female students decreased as the frequency of day time napping increased. Although, there was no significant difference in obesity-related "lack of sleep" between males and females, the rate of "being overweight" was slightly higher in female students who indicated that they experienced a "lack of sleep" than female students that indicated "no lack of sleep". While, whether intake of snacks and self-purchased snacks or not, day time napping frequency affected not to male students. However, the frequency of day time napping among females who ate snacks one or more times a day was higher (p<0.05), and a greater frequency of eating self-purchased snacks correlated with a greater frequency of day napping (p<0.01). Consequently, lack of sleep was identified as one of the factors increasing the frequency of intake of snacks and self-purchased snacks in females. Thus, this study suggests that dining behavior guidance should be given along with systematic and continual nutrition education so that the intake of snacks and self-purchased snacks can be moderated to optimize the physical and mental growth and development of adolescents.

The purpose of this study is to provide the dyeing and physical characteristics of napped knit fabrics composed of latent crimped yarn. The K/S values, dyeing fastness, thickness, bulkiness, and shrinkage characteristics of three knit fabrics were investigated. The original knit fabric (SK) was composed of 1ply latent crimped yarn (75/36) in the ground and PET DTY (70/100) in the pile loop, in order of napped process the napped knit fabric (SN) was napped SK fabric. In order to compare of latent crimped yarn content, the last knit fabric (DN) was napped 2ply latent crimped yarn were included in the same structure of SK. Dyeability of three knit fabrics was similar but the shrinkage properties of DN fabric were significant different. The bulkiness shows a tendency to increase the bulkiness as increasing the dyeing temperature, and the bulkiness of the SN was higher because of the napping process and optimal content of latent crimped yarn.

Digital Magnetic Compass(DMC) has a robust feature against interference in the indoor environment better than compass which is easily disturbed by electromagnetic sources or large ferromagnetic structures. Ultrasonic Sensors are cheap and can give relatively accurate range readings. So they ate used in Simultaneous Localization and Mapping(SLAM). In this paper, we study the Simultaneous Localization and Mapping(SLAM) of mobile robot in the indoor environment with Digital Magnetic Compass and Ultrasonic Sensors. Autonomous mobile robot is aware of robot's moving direction and position by the restricted data. Also robot must localize as quickly as possible. And in the moving of the mobile robot, the mobile robot must acquire a map of its environment. As application for the Simultaneous Localization and Mapping(SLAM) on the autonomous mobile robot system, robot can find the localization and the mapping and can solve the Kid Napping situation for itself. Especially, in the Kid Napping situation, autonomous mobile robot use Ultrasonic sensors and Digital Magnetic Compass(DMC)'s data for moving. The robot is aware of accurate location By using Digital Magnetic Compass(DMC).

This study aims to contribute to the development of male incontinence underwear with an anti-aging effect that meets customer requirements by examining the types, sorts, sizes and specifications of male incontinence underwear currently sold on the market. The results of an analysis of a total of eight commercial products are as follows. 1) Among the samples, six types of incontinence underwear were of a pull-on style like regular underwear; two types were of a pad insertion style. With respect to the underwear design, four (50%) types of incontinence underwear were brief style. The rest were drawers (3, 37.5%). Only one was of a trunk (12.5%) style. 2) With respect to size, the percentage of Size 3 was 50%, followed by Size 4 (50%). Most of the size of the underwear uses hip measurement whereas Japanese products (3, 37.5 %) use waist circumference. 3) With respect to the materials of the incontinence underwear, natural fibers such as cotton were mostly used and a polyurethane or polyester was mixed to enhance the wearing sensation and stretchability of the underwear. Finally, for the structure of the pad area, a napping finish was the largest (3, 37.5%), single knit 2(25%), twill weave 2(25%), and rib weave 1.

The purpose of this study is to investigate the effects of napping of knitted fabric on wear sensation and physiological responses. Experimental garments were four types of warm-ups made of either $100\%$ PET or $65/35\%$ P /C and either napped or unnapped respectively. Two healthy young female adults were chosen as subjects for the experiment. Experimental room conditions were as follows: Temp., $22\pm0.5^{\circ}C$ R.H., $54\pm3\%$ and Air Velocity, 0.25m/ sec or 2. 86m/sec. The subjects exercised on bicycle ergometer and rested alternatively for totally 45-min. The results are summarized as follows. 1) With napped Warm-up, chest, back, mean skin temp. and microclimates, i.e., temp., relative humidity and water vapor pressure inside the clothing, were higher than with unnapped warm-up. And there was no difference in pulse rate between napped and unnapped warm-ups. 2) Wear sensations of thermal, humidity, tactile and comfort were 'more hot' and 'more uncomfortable' in 0.25m/sec air velocity. but in 2.86m/sec condition the tactile sensation was 'better' and 'more comfortable' with napped warm-ups. According to Pearson's Correlation, among various kinds of wear sensations, tactile is most related with comfort. From these results, it can be concluded that napped fabric decreases the rate of heat trans? mission and moisture diffusion through the clothing. Therefore skin and body temp. and temp., R.H., Vapor Pressure inside the clothing are increased.

It is judged that there has to be study on bad quality of sleep along with state which university students undergo because of anxiety of finding employment and uncertain future. So 272 students' life style were measured. This study is based on Alameda 7. Also PSQI questionnaire was used to measure the quality of sleep. The results were that in the case of smoking, PSQI was 6.97, drinking 6.49, drinking coffee 7.53, nutritive conditions 6.49 and napping 6.25. These results show that smoking, drinking, drinking coffee, state of supplying nutritions and napping lower quality of sleep. Lastly, health education has to strive for promotion of university students' health and enrich quality of sleep allowing students to lead their healthy university lives.

This paper is presented simultaneous localization and mapping (SLAM) based on feature map and path-planning using modified genetic algorithm for efficient driving of autonomous vehicle. The biggest problem for autonomous vehicle from now is environment adaptation. There are two cases that its new location is recognized in the new environment and is identified under unknown or new location in the map related kid-napping problem. In this paper, SLAM based on feature map using ultrasonic sensor is proposed to solved the environment adaptation problem in autonomous driving. And a modified genetic algorithm employed to optimize path-planning. We designed and built an autonomous vehicle. The proposed algorithm is applied the autonomous vehicle to show the performance. Experimental result, we verified that fast optimized path-planning and efficient SLAM is possible.

With increased social participation of married women and with the notion of importance of pre-school childhood on human development, the importance of nurseries is being emphasized. The transformation of the traditional family system into a nuclear family system and the deterioration of the traditional child education have also put nurseries as a primal social interest. But, at present, at the end of 1994, only 10% of the children have benefitted from such facilities, the supply not being able to meet demand. Also, the spatial organization and the management of such facilities has been unsatisfactory. In this perspective, this study aims to grasp the present condition of nurseries, to investigate and analyse case studies, to suggest standards and reform measures, and based on these, to produce basic information for the formation of an architectural spatial model. We've selected investigation of present conditions and case studies, interviews, and observation as investigative methods and through these we've assessed tangible spatial planning and spatial proportion by parts. 1. The most preferred grouping method is toddler/preschooler type, and the group size and staff-to-child ratios vary according to the children's age 2. The younger children's activity rooms are located in the lower level, and the activity room of the children on the similar development stages are located adjacent to one another 3. Most of the facilities do not have the public spaces(indoor playrooms, dinning rooms, napping rooms, bathrooms, sickrooms) For dinning and napping, activity rooms are being used, and for sickrooms, director's room or staff rooms 4. As for the correlations of the spaces(home bases, activity rooms and its outdoor spaces, day-care-centers and its community), closed plan type is 90% over, and modified open plan is 10% min.
