This study was carried out to investigate the wearing silhouette of jackets according to the mechanical properties, primary hand value and total hand value of the 3 types of wool fabrics. Wool/PET(50/50), wool/PET(80/50) and wool(100%) fabrics were used as test specimens. Mechanical properties of specimens were measured by KES-FB system and primary hand value and total hand value were calculated by equation KN-203-LDY. We made three experimental jackets based on the precious jacket pattern and used Moir Photography to measure the amounts of space between the jacket clothes and body surface from the overlap cross section map. The results were as follows: 1) In mechanical properties, woo/PET(80/20) fabric showed higher bending and shear rigidity. 2) In evaluation of primary hand and total hand, wool 100% fabric showed higher NUMERI and FUKURAMI hand and total hand value. 3) From the reset of Moir Photography, the wearing shapes of the experimental jackets were influenced by the characteristics of fabrics. Except for the hip part, the garment ease of wool/PET(80/20) fabric was estimated more highly.

Twenty six subject drove screws with a screw driver into thick wooden sheet at three vertical and horizontal locations. Subjects drive screws for 3 minutes at each location and they assessed the conditon using the psychophysical scale. An ANOVA showed that only vertical location was a signicant factor in determining the pain ratings of various body parts. Driving screws at elbow height on the vertical surface ans with the lower arm close to the body on the horizontal surface were the work locations with the smallest ratings of perceived pain and discomfort. Wearing gloves had significant effects on reducing the pain of the hand.

Wearing ease is a critical factor when designing special uniforms such as flight pilot's garment and should reflect occupational properties for better performance. This study measured skin surface on 31 areas in seven postures that refer to the pilot's occupational postures as well as made six prediction models including linear mixed model (LMM) for each body part to find the best fit model. Skin surface measured from 3D body scanned images of 11 male pilot participants. There were significantly positive and negative changes in various areas from standing posture (P1) to dynamic postures (P2-P7). Six models were designed in various compositions using stature and chest circumference as fixed effects and subject and posture as random effects. The best models were linear mixed models with one fixed effect (chest circumference or stature, varies with body parts) and two random effects (subject and posture). The results of this study provide reference data to set wearing ease for pilot's garment and suggests a new methodology in this research area, but verifying the effect of diverse independent variables is left for future studies.

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.

Objectives : This study was conducted to investigate the actual state of dental hygienist's behavior for infection control during dental practice and radiologic examination and to evaluate the dental hygienist's awareness of the importance of infection control in dental office. Methods : A survey on 218 dental hygienists was carried out. The respondents to complete a questionnaire were the dental hygienists who were in dental office on Gwang-ju area or attended complementary training conducted by the Seoul Branch of Korean Dental Hygienists Association in April 2010. The data were collected and analyzed with $x^2$ test, t-test, ANOVA using SPSS program. Results : The ratios of educational experience for infection control in dental practice and radiologic examination room accounted for 87.6% and 30.3% respectively. Behavior degree of mask-wearing in the dental practice and radiologic examination room were $4.60{\pm}0.70$ and $3.77{\pm}1.09$ respectively. Behavior degree of glove-wearing in the dental practice and radiologic examination room were $4.40{\pm}0.91$ and $3.68{\pm}1.17$ respectively. In case of the relation between educational experience and behavior degree in mask-wearing or glove-wearing, there was no significant difference in the performance of mask or glove wearing during dental practice, and mask-wearing during radiologic examination. However, there was a significant difference (p<0.05) in the performance of glove-wearing during radiologic examination, which revealed that behavior degree between the respondents having educational experience and the others no having it were $3.92{\pm}1.19$ and $3.58{\pm}1.14$ respectively. The surface disinfection control for radiation and protective equipments used in radiologic examination room was done by occasional needs without premeditated schedules. Conclusions : The result of this study shows lower behavior degree during radiologic examination compared with one during dental practice. We suggest that there are needs to raise the awareness of infection control and to improve infection control behavior, and through this study, the importance of education was verified.

The effects of individual sweating rates on thermophysiological responses during the decrease phase of clothing surface temperature (Tcs) with cotton (C) and polyester (P) clothed subjects were examined. Seven women subjects were exposed in a climatic chamber at ambient temperature of $27.2^{\circ}C$, relative humidity of 50%, and their lower-legs were immersed in a water bath at a temperature of $35-41^{\circ}C$ for 70 min. During water immersion, Tcs in C-clothed subject rose immediately after the onset of sweating and then Tcs fell gradually. In C-clothed subjects, Tcs decreased directly (p<0.05) in proportion to total sweating rate (TSR), however no significant correlation was observed in P-clothed subjects. The relationship between TSR and changes in mean skin temperature, and skin blood flow showed negative correlation when wearing C-clothing (p<0.05), however, no significant correlation when wearing P-clothing. Individual TSR was correlated with threshold rectal temperature for sweating onset (p<0.05) with C- and P-clothed subjects. The results showed that individual TSR had significant effects on not only Tcs but also on thermoregulatory responses during the Tcs decrease phase.

This study analyzed the effect of wearing a vest with an attached electric fan. Korean men in their 20s were given test "fan vests" equipped with fans on the chest, stomach, upper back, or lower back to wear. Participants wore them in a climate chamber set to replicate a summer environment (30±3℃, 75±1%RH, 0.2 m/sec). Subjective sensations and surface temperatures were measured. The attached fan on the front of the vest lowered the temperature of the vest and the skin surface where the fan was positioned, regardless of whether the wearer engaged in exercise. However, a fan attached to the lower back of the vest was effective in lowering the lower back of the vest as well as the upper back, back of the arm, and back of the neck. In addition, subjective evaluations indicated that a vest with fans attached to the stomach and lower back provided a cool sensation. However, it was confirmed that the design of an auxiliary tool capable of dispersing the weight is necessary since the weight of the fans can interfere with the comfort of wearing the vest.
