This study applied a segmented hard shell design on knee protectors for children with the objective of increasing mobility. The prototype of the hard shell that does not correspond to movement of the body among components of the knee protector was developed. Surface modeling was conducted based on 3D knee data to enhance comfort through optimized fit on the knee joint where the hard shell would be worn. For this, previous studies on changes in skin near the knee joint during knee flexion were reviewed to establish basic segmental lines. The basic design included six segments, and the number of segments was used as the design variable by increasing or decreasing it to 0, 3, 6, 9, and 14 segments. A prototype was produced from 3D printing with TPU material, worn for wearing assessment. Results revealed fewer numbers of segments resulting in less fit with the body, while actual appearance was stable. Meanwhile, the number of proper segments improved better fit with the body during movement. The wearing assessment revealed the amount of gap reflects change in skin length depending on movement. Assessment results demonstrated basic segment design, S6 with 6 segments, had the best design and most optimized fit. Findings in this study can provide key data for designing knee protection products for children.

This study collected the basic data required to develop a slim-fit jeans pattern for upper grade elementary school girls. First, a fit evaluation was made by selecting five slim-fit jeans of ready-to-wear brands. Subjects were four girls aged 11-12 with an average body size that evaluated the appearance and motion functionality of five brands of jeans. Five experts also evaluated their appearance. Second, pattern sizes were analyzed and compared with the average size of upper grade elementary school girls by measuring the pattern sizes of five brands jeans. As a result, Brand A received a high score in appearance and motion functionality. Brand E scored high with Brand A in appearance, while Brand E had the lowest score in motion functionality. For most of the five brand jeans, (+) ease was added to include a wide range of body sizes for upper grade elementary school girls, but the hip circumference, thigh circumference, and knee circumference of Brand E jeans were smaller than the average size of girls. The (-) ease was applied to make the figure look slim, which resulted in a high appearance score. However, since Brand E received a low score in the motion functionality, it could be seen that the (-) ease was not suitable for subjects although the material was stretchable. The result of this study will be used to develop a slim-fit jeans pattern suitable for upper grade elementary school girls.

This research predicted the fit of the basic bodice patterns worn on adolescent girls' 3-dimensional scanned bodies. Six 3-dimensional scanned bodies were selected from the sixth Size Korea data. Each of them had good body posture and represented one of the three garment sizes: 79-160, 82-160, and 85-160. Experimental basic bodice patterns were drafted by three basic bodice pattern making methods. The fit of the basic bodice pattern was analyzed by the CLO 3D virtual clothing system. The results showed that the experimental basic bodice patterns did not fit well at the neck, shoulder, and back for adolescent girls. The fit of the basic bodice patterns varied by pattern making method or size. The basic bodice pattern A with the waist darts ending above the breast line showed the best fit among the three different types of experimental pattern. Among the three sizes 79-160, 82-160, and 85-120, size 79-160 basic bodice pattern showed the worst fit for adolescent girls. The results show that the placement and size of the bodice darts affect the basic bodice pattern fit. The basic bodice pattern making method of size 79-160 for adolescent girls should be studied in a future study.

This study helps develop a cool body armor that maintains a tight-fit configuration to the body surface and evaluates the performance of newly developed body armor in a wear test. Three types of body armor were used for evaluation. One was a tight fitting body armor that was constructed to improve the degree of fit and ease of movement for Korean soldier using 3D technology. Another was ventilating body armor with attached spacers on the shoulder to reduce the thermal stress on the soldier. The third was a prevailing body armor produced by a Korean body armor company. In order to evaluate the performance of the body armor, a human wear test, a thermal mannequin test, and computational fluid dynamics (CFD) were executed. Five subjects participated in the wear test. Subjective wear sensation, total amount of sweat and dynamic change of clothing microclimate were observed during and after exercise on a treadmill; subsequently, it was found that subjects rated tight fitting body armor and ventilating body armor lighter, drier, and easier to move than the conventional body armor (p<.05). Total amount of sweat was the least in the case of ventilating body armor. The thermal resistance and vapor resistance of the ventilating body armor were improved remarkably. In addition, the skin temperature of the ventilating body armor with spacers was lower than the tight fitting body armor by at least $1^{\circ}C$ in the CFD result. It is noted that thermal-wet comfort of the 3D body armor with ventilating feature is superior to the conventional body armor, especially when the ventilating channel is not closed due to a backpack.

When we develop the tight-fit 2D pattern from the 3D scan data, segmentation of the 3D scan data into several parts is necessary to make a curved surface into a flat plane. In this study, Garland's method of triangle simplification was adopted to reduce the number of data point without distorting the original shape. The Runge-Kutta method was applied to make triangular patch from the 3D surface in a 2D plane. We also explored the detailed arrangement method of small 2D patches to make a tight-fit pattern for a male body. As results, minimum triangle numbers in the simplification process and efficient arrangement methods of many pieces were suggested for the optimal 2D pattern development. Among four arrangement methods, a block method is faster and easier when dealing with the triangle patches of male's upper body. Anchoring neighboring vertices of blocks to make 2D pattern was observed to be a reasonable arrangement method to get even distribution of stress in a 2D plane.

This study was initiated to study suitability of the apparel sizing systems that utilized in women's ready-to-wear market. To achieve this, the researchers surveyed 383 women from the ages of 18 through 59. The result of this study are followed. 1) The targeted age of the apparel brand does not always correspond with the purchaser's age. The subjects tend to prefer the brands targeting younger women than their age. The women who prefer the brand targeting younger women than their age were less satisfied with the jacket size available in Korean apparel market. They also took into consideration their body size. 2) The subjects who prefer the brands aimed for younger women were dissatisfied with fit at waist and hips. 3) The result of this study also shows that the more sizes are needed for short and tall women. The subjects pointed out that hips of the pants gave worst fit. 4) KS standard size designation system which listed body measurements bust-hips stature was not well known to the consumers.

The purpose of this study was to provide information on how to improve the current sizing system of infant coveralls through analysis of the present system. In order to compile the information about dissatisfaction with the appropriateness of the fit of infant coveralls, a questionnaire was administered to mothers of 241 infants (aged under 36 months) living in Seoul, and analyzed using the SPSS WIN.10.0 program. Also, the manufacturers'basic body sizes were investigated. The results of this study were as follows : 1. The results of the comparison between the manufacturers'basic body sizes and the body measurement values obtained as the physical standard of the nation(1997) show that in terms of length and hip circumference, the manufacturers'body sizes were larger. On the other hand, in the waist circumference, the manufacturers'body sizes were smaller than the national average. 2. Research on the production sizing system of domestic and international brands, showed that the sizing interval of domestic brands were 6 months, whereas the international brands were 3 months f3r infants under 12 months. 3. Concerning fit, the areas causing most dissatisfaction were: the trunk length, sleeve length, inside leg length, and neck depth. The results showed that dissatisfaction with the suitability of the sizing of current infant coveralls according to the body part differed among the groups according to the month of age.

The present study describes the analysis of the multiphasic growth function (MGF) to body weight in laboratory and wild mice. Three genetic groups of laboratory mice (Mus musculus domesticus) designated $CF_{{\sharp}1}$, C3H/HeNCrj and C57BL/6NCrj, and a genetic group of Yonakuni wild mice (Mus musculus molossinus yonakuni, Yk) were used. Mean body weights of each genetic group-sex subclass from birth to 69 days of age taken at 3-day intervals were analyzed by a monophasic, diphasic and triphasic functions for describing growth patterns. A comparison among the three functions of the MGF was based on the goodness-of-fit criteria: residual standard deviation (RSD), adjusted R-square (Adj $R^2$) and Akaike's information criterion (AIC). Result of this study indicated that body weight averaged heavier for males than for females. Among the four genetic groups within both sexes, $CF_{{\sharp}1}$ showed the highest, subsequent followed by C3H/HeNCrj, C57BL/6NCrj and Yk. Comparison among the three functions revealed that the triphasic function was the best fit to growth data, with the lowest RSD, the highest Adj $R^2$ and the lowest AIC, for the four genetic groups. For the triphasic function, RSD within each genetic group-sex subclass was similar for males and females. Adj $R^2$ was 0.999 for all genetic group-sex subclasses. AIC for laboratory mice males and females ranged from -70.48 to 66.50 and from -92.81 to -68.64, respectively; whereas for Yk wild mice males was -74.29 and females -78.42.
