This study evaluates the fitness of brassieres through size measurement, comparative pattern analysis, cross section map analysis, 3-D shape analysis number, and fitness evaluation with a focus on domestic and overseas brands. Experimental brassieres were selected as mold brassieres of 3/4 cup in 75A size that is considered a popular design. Brands of selected brassiere were 2 domestic brands (A, B), 1 licensed brand (C), and 2 overseas brands (D, E). Subjects were 8 women in their early 20's. Data were analyzed by descriptive statistics, analysis of variance, reliability analysis, and factor analysis. The results were as follows; the size and pattern of brassieres showed a difference by each brand even though brassieres are the same design. In the wearing effect of brassieres, overseas brand brassieres played a major role in the breast-up effect, but they were not appropriate for the somatotype of Korean women. Domestic brand brassieres showed the volume-up effect, that was confirmed by the increasing bust circumference, bust depth when subjects wore it. In addition, the licensed brand brassieres showed the correction effect of body shape. Therefore, when purchasing a brassiere, the most important condition is to consider the individual characteristics of the somatotype. The results of factor analysis through a functional evaluation show that wearing satisfaction, size satisfaction, and the position of the bust point were important factors for fitness satisfaction and purchase.

[Purpose] We conducted a meta-analysis to evaluate the effects of Taekwondo training on the physical fitness factors in Korean elementary students comprehensively and quantitatively. [Methods] We classified research studies published until November 2018 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and selected a total of 17 research items; a meta-analysis of these items was then conducted. We used the Comprehensive Meta-Analysis 3.0 and Review Manager 5.3 to analyze the mean effect size, study quality, and publication bias. [Results] Taekwondo training improved the cardiopulmonary endurance, muscle endurance, and power of the elementary students, but was not practical or less useful on other physical fitness factors. The meta-regression analysis of the cardiopulmonary endurance and power items showed that the effect size was large when the sample size was small. Therefore, it is necessary to consider the sample size in interpreting the effect size for these two items. Further, during correction of the publication bias for the power items, the improvement effect by Taekwondo training was eliminated. [Conclusion] Taekwondo training is helpful for improving the cardiopulmonary endurance and muscle endurance of Korean elementary students but is not useful for other physical fitness factors.

This study investigated domestic and foreign cycle wear sizing systems for the domestic market and provided basic data for development of a high functional cycle wear with excellent fitness qualities. Each brand was found to have different dimension items and different sizes as well as size deviation and range according to each item. Therefore, a size selected by referring to the dimension items would be expected to have confusion when selecting a size. Domestic brands are able to selects sizes relatively easily because they suggest sizes mainly by height and weight (which are a universal size). However, the development of a sizing system for domestic cycle wear brands is needed because each brand have different sizes according to its dimension items. Foreign brands are also different from domestic brands in size marking items and sizes according to items. Therefore, the establishment of a sizing system standard for foreign brands is necessary because there could be a problem with fitness in the same sizes selected for domestic brands. Cycle wear is also able to cover various body types due to the elasticity of its material; however, and evaluation of fitness and a follow-up study will be necessary to develop cycle wear with a fitness that is proper for a Korean body type.

A fitness facility in an apartment complex is not a simple sports facility. It has important roles in improving the residents' physical and mental health, and in forming a sense of community. This study analyzed the number of users in the fitness facility of the apartment complex, which is a significant criterion in determining the dimension. A comparative analysis between the past and the present function and dimension was performed in finding out the optimal solutions. In conclusion, the number of users in the fitness facility is influenced not by the number of households in the complex but by the facility's size and creating a desired environment. The users' favorite sports equipments were figured out to meet those needs. Moreover, comparing the facilities' size, user satisfaction, area per person, an optimal dimension for the facility, and rates of equipments were found out.

Reproductive activity in the economically important insect, Antheraea mylitta is very important because the female reproduces only once in her life time and the aging is very rapid and costly. It is a capital breeder and strictly a monoandrous species. To know how strategically the insect behaves and the male allocates its ejaculate resource more prudently during its successive mating with virgin females to maximize its own fitness and the fitness of the female with whom it mated, both being most important to sericulture industry. So, the present study was undertaken and the results revealed fresh and virgin females always prefer to mate with fresh virgin males (84%) and receives high dose of ejaculates leading to higher hatchability than to virgin males of one day old (13.7%) and one day old males with mating experience (2.3%). The ejaculation size (as referred to eupyrene sperm count in the ejaculation) declined significantly over successive mating (r = -0.9931, P < 0.001), so also the male body weight (r = -0.9560, P < 0.001). The quantity of ejaculate passed to female also dramatically declined during aging (r = -0.9982, P < 0.001). It was found that male weight contribute substantially to the quantum of ejaculate (r = -0.9519, P < 0.001), so also higher fecund females receive relatively more ejaculate than the lower group to reach higher reproductive fitness. The life time fecundity was found to be $334{\pm}31$.

Fitness of clothes becomes a major concern in apparel industry. In order to improve clothing fitness, it's very important to suggest a systematical sizing system. The Purpose of this study was to suggest a standard sizing system for junior-high school girls'lower clothes. The subjects were 402 middle-high school girls of 13 to 15 year-old. 4 clusters were categorized by cluster analysis and the sizing system was classified according to four lower body types. The size intervals of waist girth and hip girth were 3cm and 4cm respectively. The most frequent size were 64-86 in the short and small figure type 1,67-90 in the fattest figure type 2, 61-86 in the average size type 3 and 64-90 in type 4 taller than others types. The sizing system, which had frequencies more than 4%, was classified 9 cases, 11 cases, 8 cases and 9 cases respectively by lower body types. This result will contribute to clothing fitness of consumer and the amount of production.

The purpose of this study is to examin wearing satisfaction and needs of the caregivers' uniforms. The questionnaire survey was conducted on 303 who are serving in the geriatric hospital and general hospitals in Seoul and Gyeonggi, Chungcheong region. It was coherently found on the whole that the irrelevance to the fitness of size system influenced the discomfort, and the relation between discomfort and satisfaction revealed negative-correlation, and the higher the discomfort is and the lower satisfaction is, the higher their improvement needs are. Particularly, the higher the discomfort on the fitness of size system is and the lower its satisfaction is, the higher the improvement needs on the size system and activities are. As a result, the clothing construction and the selection of materials for the complement of the fitness and discomfort's incongruity is required. Namely, the yoke of the back area and the various detail for the activity, the materials satisfying stretch, good-touch, antibiotic functionality, and the expansion of the size system are needed.

This study was performed to investigate purchasing practice and size satisfaction in order to offer basic data to establish marketing strategy and produce ready-made clothes for the male college students according to their body type. For data analysis, crosstabs, factor analysis and one-way ANOVA were used. Results were as follows; first, this study considered the somatotype distribution of male college students. The results showed that inverted triangle -shaped torso was the ideal somatotype in all the classified four actual somatotypes. Second, people in standard body types significantly considered price and appearance such as design, color, pattern and price while people in triangle-shaped torso placed the most importance in the practicality and wearability. People with inverted triangle-shaped torso was found to significantly consider the perceptual quality such as brand, a/s and fashion. Third, this study considered the wearing satisfaction of ready-to-wear. The respondents placed more emphasis on the practicality and wearability as their actual somatotypes were not ideal for them. Fourth, the examination of the difference in size fitness depending on clothing by somatotype when wearing ready-to-wear showed that breast on the top was small when wearing it in the remaining somatotypes except for standard somatotype. The upper body showed better size fitness in triangle-shaped torso. There is a difference in fitness according to somatotypes classified by the form factors even though they have the same body mass index.

The objective of this study is to develop a sizing system of fitness clothing that can properly accommodate various body sizes of Korean senior women. The sizing system of upper and lower fitness clothing was developed in the present study by selection of key variables, identification of size category candidates, and determination of an optimal sizing system. First, key anthropometric dimensions (stature and bust circumference for upper clothing and stature; waist circumference for lower clothing) were identified by factor analysis on the direct body measurements (n = 272) and 3D whole-body scan data (n = 271) of Korean senior women in Size Korea. Second, sizing system candidates based on the key dimensions of upper and lower clothing were explored using a grid method and an optimization method. Lastly, among the sizing system candidates, optimal sizing systems of upper and lower clothing were selected in terms of accommodation rate. Five size categories (short/small, short/medium, tall/small, tall/medium, and tall/large) were selected as the optimal sizing systems of upper and lower clothing with 89% and 78% of accommodation rate, respectively, for the Korean senior women. The anthropometric characteristics of the representative humans of the optimal size categories would be of use in the design of fitness compressive wear for the better fit and effectiveness of exercise and health of Korean senior women.
