For understanding skin temperature based on clothing design from a viewpoint of comfortable wearing, the skin temperature, physiological reactions(body temperature, blood pressure and pulse) and physilolgical response(thermal sensation, comfort sensation and perceptive sweaty sensation) were measured on condition tha t5 naked healthy male exposed to serveral environmental temperatures,( $20{\pm}1.0^{\circ}C$ ,$28{\pm}1.0^{\circ}C$ and $32{\pm}1.0^{\circ}C$). As the results of this testing, the regional skin temperature was varied for 90min just after expose to those the environment but was generally stabilized for the nest 90min. It was proved the difference of the regional skin temperature at low temperature environmental($20{\pm}1.0^{\circ}C$) was larger than at high temperature environmental($32{\pm}1.0^{\circ}C$) and inder serveral environmental temperature,the degree of the regional skin was not equal. Except in case of the thigh, the front of all regional skin temperature turned out higher than the back of them. According to change of environmental temperature, body temperature and pulse were altered. In the pshycological response, 'thermal sensation-comfort sensation' was felt to 'slightly warm - comfortable' at $28{\pm}1.0^{\circ}C$of the environmental temperature, and 'perceptive sweaty sensation', wneh it was said 'sweat' at only $32{\pm}1.0^{\circ}C$ of it.

The purpose of this study is to assess abdominal sensation after free TRAM flap for breast reconstruction. 74 patients underwent breast reconstruction with free TRAM flap by authors and were followed up to check the sensation on abdomen following the surgery at the out patient clinic. They are compared with 20 female volunteer controls. Abdomens were divided into 13 zones, and assessed for superficial touch, superficial pain, temperature, two-point discrimination, and vibration. For all five sensory modalities, subjects were found to have decreased sensation in the umbilical and infraumbilical regions. This was statistically significant compared with controls. Division following pedicle dissection showed more reduction of sensation than non-dissection side. Both Inguinal areas below the donor site closure also showed markedly decreased sensation. Sensation on most area of abdomen recovered in postoperative 1 year, however, there were remained hypoesthesia in umbilical and infraumbilical area after post operative 1 year. This study clearly demonstrates that there is a significant and persistent reduction in abdominal sensibility following free TRAM flap surgery.

The purpose of this study was to investigate the sensation seeking tendency and knitwear purchase behaviors of high school girls. The data were obtained from 475 high school girls at 6 high schools located in Daejeon. The method of study is a survey consisted of sensation seeking tendency items, knitwear purchase behavior items and demographic attribution. Data were analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS WIN 17.0 program. The results of study are as follows. First, high school girls generally liked knitwears by reason of comfort and activity. Most girls purchased the knitwears to wear ordinary casual wear(81.5%). They usually thought sweater and cardigan to be representative of knitwears. Also, they mostly purchased the knitwears of simple and active design, achromatic color, 100% cotton, and solid or simple stripe pattern. The design and price were considered as important evaluation criteria in knitwear purchase. The information sources used by them were store display, friends, and internet. Second, the knitwear purchase behaviors of high school girls showed the difference between groups with high- and low-sensation seeking tendency. The most important factor of knitwear purchase was an unique and characteristic design in high group and a simple and active design in low group. In conclusion, high school girls liked knitwears and had different knitwear purchase behaviors according to the sensation seeking tendency.

The purpose of this study is to investigate the physiolosical responses and subjective wear sensation to the clothes with different cellulose composition. The experimental garments were four types of cellulosic fabrics, respectively composed of $100\%$-cotton, $100\%$-Rayon, cotton/Flax 85/15, and rayon/Flax 85/15 (weft blended), were sewn in blouses with half-length sleeves. Four healthy women were chosen for this experiment. The condition of the experimental room were in two environments: Temp., $25{\pm}1^{\circ}C$, R.H. $60{\pm}3\%$ and Temp., $30{\pm}1^{\circ}C$, R.H. $70{\pm}3\%$, and air velocity was maintained at 0.25 m/sec. The results are as follows. 1) At $25^{\circ}C$, rayon blouse showed the pleasantest feeling because of its excellent humidity sensation and tactile sensation. At $30^{\circ}C$, rayon and flax blended blouse showed most comportable sensation. In both environments, blouse of $100\%$ cotton showed the least pleasant because of high vapor pressure inside the blouse and bad tactile sensation. 2) Vapor pressure inside the blouse and tactile sensation play the most impotant role in comfort. Consequantly the blouse made of $100\%$-cotton which bring low air permeability, moisture regain and water vapor permearbility showed more unpleastness than rayon blouse because it raises temperature, relative humidity and vapor pressure inside the blouse under the hot circumstances In the conditions with much sweat, rayon and flax blended blouse with high stiffness increases comfort better than $100\%$ rayon because the former prevents sticking to the skin.

Purpose: The aim of our study was to evaluate natural recovery of neurologic injury after minor dental surgery based on subjective neurologic evaluation. Materials and Methods: From December 2005 through July 2009, 30 patients from Seoul National University Bundang Hospital were identified as having been treated with minor dental surgery. The patients were composed of 12 men and 18 women, with a mean age of 50.6 years. The median duration of this study was 62 weeks. Results: The patients were treated by implants (17 cases), tooth extractions (6 cases), bone grafts (4 cases), inferior alveolar nerve transpositions (2 cases) and periodontal surgery (1 case) prior to the occurrence of altered sensation. Areas of altered sensation after minor surgery included the lip (36.7%), chin (30.0%) and tooth (21.7%), and at final follow-up, there was no change of ranking. Altered sensations expressed by patients included numbness (33.3%), discomfort (22.9%), relieving sense (14.6%), tingling (14.6%) and itching (14.6%). There was no change of ranking of altered sensation at the last follow-up. Patients experienced the altered sensation always (47.8%), during tactile stimulation (26.1%), when chewing food (13.0%), and talking (13.0%). Mean visual analogue scale (VAS) was $3.43{\pm}2.84$ for pain and $6.64{\pm}2.72$ for paresthesia. VAS of pain was decreased significantly between the first visit and the end of follow-up, and paresthesia also showed a significant difference. Conclusion: Altered sensations may occur at any time after minor dental surgery, but we observed that natural recovery of altered sensation occurred as time went on.

The purpose of this study is to suggest sleeve cap height with a satisfying wearing sensation and appearance on jackets for women in their twenties so that high-consumer demand jackets can be produced. Five experimental jackets with sleeve cap heights of [(AH/3)-1cm], [(AH/3)-0.5cm], [AH/3], [(AH/3)+0.5cm] and [(AH/3)+0.8cm] were made for 30 subjects to try on after which the subjects were then surveyed for their assessment of appearance, wearing sensation and preference. On the basis of the results, the optimum height of the sleeve cap has been proposed along with the following contents and results of this research. 1. [AH/3] [(AH/3)+0.8cm] of sleeve cap height was assessed to beof desirable appearance. 2. [AH/3] of sleeve cap height garnered a high opinion in terms of intuitive wearing sensation, while [(AH/3)-1cm] [AH/3] were the heights with overall satisfaction of intuitive and movement wearing sensations. If discomfort in the upper sleeve at 'straight arm' posture can be tolerated, the sleeve cap height can be set to [(AH/3)-1cm]~[(AH/3)+0.5cm]. 3. [AH/3] and [(AH/3)+0.5cm] were found to have a high preference among wearers, which indicated that the women in their twenties prefer a slim type of sleeve, putting appearance above wearing sensation. Consequently, [AH/3] is desirable when appearance, wearing sensation and preference are considered, [(AH/3)+0.5cm] is fit for business uniform for static duties or formal dress focused on aesthetic impression and [(AH/3)-1cm]~[AH/3] are desirable for work clothes when considering active duties.

The purpose of this study was to better assess and understand current needs and wearing sensation, including clothing behavior for early elderly women in the Korea and USA. The subjects in this study were 135 and 173 early elderly women in the Korea and USA. This research was done by a survey method and chi-square test. The major objectives of this study were as follows; First, it was found that the early elderly women of Korea utilize mostly human information as information source when purchasing clothing, whereas those of USA mostly media information. The women of Korea were found to put most emphasis in esthetic aspects of clothing, whereas those of USA in comfort. The most frequently worn clothes by the early elderly women of Korea were jumper, T-shirt and slacks, whereas jacket, sweater and slacks by those of USA. As for skirt, flare skirt was highly preferred in Korea, whereas A-line skirt in USA. Second, regarding the wearing sensation of ready-made clothing, the wearing sensation of jacket was found to be worst on the shoulder in Korea, whereas on the waist in USA. And the early elderly women of both Korea and USA had poor wearing sensations due to the length of sleeve, of trouser, of skirt and of one-piece dress. The comparison of the clothing behavior and wearing sensation of the early elderly women between Korea and USA showed a greater difference in clothing behavior than in wearing sensation.

In the field of 'Human Vibration', it has been interested subjects to make equal sensation curves related to translational and rotational direction of whole-body, hand-transmitted and head-transmitted vibration, etc. When we consider the vibration of a vehicle, the main factor is vertical whole-body vibration. Until now, most of equal sensation curves used to derive frequency weighting function had been made using Western people. However, because of the inherent differences (for example, characteristic and shape of body parts, muscular and cellular tissue) between the Western people and the Oriental people, equal sensation curves based on Oriental people might be required. Also, the weight differences between the samples which consist of average-weighted and over-weighted group might cause the difference of equal sensation curves. So, in this study, 20 male Korean people were used to find equal sensation curves subject to vertical whole-body vibration on seated posture. Among 20 males, an over weighted group consisted of 10 male persons and an average weighted group was the others. Integrating and analyzing the data of two groups, some of non-parametric tests such as 'The Wilcoxon Signed Rank Test' and 'The Mann Whitney U test' were used.

The human sense of touch provides us with an important source of information about our surroundings. Because of its unique position at interface between our bodies and the out world, touch sensation supplies sensory data which helps us manipulate and recognize objects and warn of harmful situation. But tactile sensation was recognized less important than visual sense and auditory sense but it plays an important immersing role in virtual reality and computer game. Tactile sensation can be used to influence to objects according to power and supplied sensory feedback to the player in a virtual environment. This paper investigated the characteristics of tactile sensation of human being and proposed method of sturdy using force sensing sensor, simple force modeling and data structure form for virtual reality and computer game. As a result, force distribution, depth, center point can be calculated using sensor output and this information is very effective to specific position for actions and reactions. This study can used as basic information for tactile sensation and it's application in computer game and virtual realty.

The purpose of this study was to examine to what extent teenagers accepted sexual relations, and to determine in which way that was affected by their disposition of stimuli, one of the psychological factors, and by their adjustment to school life, one of the environmental factors, as those factors seemed to have impact on that. This study was of descriptive correlational approach, and the subjects were 962 boy and girl students randomly selected from regular and business high schools. The data were collected from May through July 2002, and SPSS win 10.0 program was employed for data analysis. The major findings of this study were as follows; First, the students investigated got a mean of 44.49 marks on school adjustment. Their sensation seeking got an average of 130.10 marks. Their sexual allowance got a mean of 38.90 marks. Second is to regard the influence of their general characteristics on school adjustment, sensation seeking and sexual allowance. school adjustment was significant on gender, grade, career track, religion, school record, economic state, sexual intercourse. Sensation seeking was significant on all of their general characteristics. Sexual allowance was significant on all except economic state. Third, concerning correlation among sexual allowance, school adjustment and sensation seeking, sexual allowance was positively correlated to sensation seeking and negatively to school adjustment. The above-mentioned findings suggested that school adjustment and stimuli pursuit was associated with sexual attitude, and the findings of this study are expected to make any contribution to creating an ideal sexual culture for the youth.
