The major objective of this study is provide to basic data for developing of new chicken products. The findings from this study are as follow. Eating times of chicken is increased in comparison with National Livestock Cooperative Federation(NLCF) & Korea Chicken Council(KCC)s survey results. Consumers are frequently having fried chicken and this results are no difference in KCCs survey results. In eating place of chicken, consumers are mostly preferred to have chicken at home. In the use of chicken consumption, the ratio of replacing meal is high and this is no difference in previous study. However there are a few differences in consumption behavior by age and gender.

Two difference cavitation models based on the homogeneous mixture model are used to study cavitating flows through converging-diverging channel. Here, the cloud cavities, pressure distributions and other results have been obtained and compared to evaluate two cavitation models. What's more, differences are observed in the simulated results, due to the differences in characteristics of each model. Analytical results shows that the new improvement cavitation model is validated to have better effects on simulating cavitating flows

There have been many studies from the genetic system to physical activity and emotional expression such that there are gender differences. The purpose of this study was to determine how the structural characteristics of cortical thickness differ between males and females. This study used data from the Human Connectome Project (HCP). To analyze age-specific sexual dimorphisms of cortical thickness, selected 8-80 year old subjects were divided into five detailed age range groups according to each criterion. A total of 1,700 individual brain MRI T1 data were registered in stereotaxic space for analysis and classified into white matter (WM), gray matter (GM), and cerebro-spinal fluid (CSF). For surface-based analysis, the WM/GM surface was reconstructed from a spherical polygon model with 40962 vertices per hemisphere, and each vertex was extended to the GM/CSF boundary. Cortical thickness was then measured between each vertex using the t-link method. In the statistical analysis, intracranial volume was used as a covariate to exclude the effect of the difference in brain size of each individual, and the result of using age as a covariate was added to confirm the age effect within each group. Gender differences in cortical thickness had significant results by group. This may be an index to explain diseases with sexual dimorphism in prevalence or become a basis for explaining the characteristics of each sex that appear in behavior, personality, and aging. Therefore, the results of our study could be a criterion for age classification in future studies and for understanding 'normal' sexual dimorphism.

The purpose of this study was conducted to make a comparative biomechanical analysis of X-factor and X-factor stretch during driver and iron swing. The subjects were composed of 10 professional golfers with more than 10 years career. The result was as follows: First, the analysis of the back swing with driver and iron swing showed no differences statistically between both the timing in horizontal rotating of shoulder and hip, the time required for X-factor stretch also showed no differences statistically. Second, the back swing with a driver swing showed more maximum horizontal rotation of shoulder and hip joint than the back swing with an iron swing, but the twist of shoulder and hip that was X-factor stretch angle showed no difference. Third, the GRF of the max value for the left and right foot during shoulder and hip horizontal rotation of back swing showed no differences statistically in the movement of driver and iron swing during the back swing, and the GRF of X-factor stretch for the left and right foot showed no differences statistically in driver and iron swing. Therefore the result of this research showed that the operation of torso(X-factor stretch) and weight shifting were similar although the horizontal rotation of body was different during the driver and iron swing.

The purpose of this study was to analyze difference in clothing preference based on the perceived body types. The objects of this study were to prepare for the establishment of a marketing strategy and alternative plan intended for users operating in a subdivided market, after analyzing the differences in clothing preference based on the perceived body types. The respondents comprised 192 female adults, who were residents in Busan. The questionnaire was composed of three sections: style, textile, and color of clothing. Data were analyzed by frequency, factor analysis, cluster analysis, discriminate analysis, and ANOVA. Cluster analysis was employed to identify groups of respondents based on the five delineated measure items. Based on the findings, three distinct groups were formed: thin, normal, and obese. The result of this study showed statistically significant differences among the three groups in terms of style, textile, and color of clothing, as well as in terms of demographic characteristics. Marketing and management implications for effectively targeting the segments are discussed.

Due to the recent COVID-19 pandemic, SMEs are forced to converge themselves into online business to cope with the rapidly changing business environment. However, due to various difficulties of becoming an online business, most SMEs choose to use services provided by the online sales platform. These platforms offer valuable support such as DSS in return for the high amount of commission fee. We analyze a novel data set from Naver Corporation's 'Smart Store' platform with the quasi-experimental method (propensity score matching technique combined with the difference in differences analysis) to analyze DSS usage and SME's performance empirically. Our results suggest that DSS usage leads to an increase in SME's sales performance in means of sales frequency and sales amount. Additionally, we have found weak support that DSS usage enables SMEs to attract customers better than those not using DSS.

The shape of the male beard to be examined in this study was set as a mustache. This study used frequency analysis and cross-tab analysis to conduct T-test and one-way variance analysis using 300 final responses from the questionnaire that presented preference and non-preference reasons and demographic characteristics along with preference and non-preference options to measure the likability of whiskers. As a result of the study, there were differences in men's preference and non-preference for each beard formulation, and the level of difference was statistically significant between the male and female groups and the age group. In addition, it was found that each group category showed a difference in the reasons for judging likes/dislikes by beard form. There are differences in preference and non-preference according to men's beard formations, and it was confirmed that there are various differences according to perceptual characteristics in the main reasons for favorability and dislike, which are the basis for judgment. Through these results, academic and practical implications were presented in the field of beauty.

This paper aimed to investigate the difference of clothing behavior and desired image according to individualism-collectivism cultural tendency for women. A survey of 217 adult women was conducted from November to December 2006, mainly in Daegu. Reliability, frequency, percentage, factor analysis, ANOVA, t-test, Tukey test and an -analysis were used for data analysis by using SPSS WIN 11.0 package. The results were as follows: First, while the group with a higher tendency toward individualism valued personality and convenience above everything else, the group which has a higher tendency to collectivism disposition has a much greater interested in conformity and brand-orientation. Second, while the group with a higher tendency toward individualism pursued an bold image for their clothing, the group with a higher tendency toward collectivism preferred a feminine and plain image. Third, regarding the individualism-collectivism and demographic peculiarity, there were no significant differences between the two groups according to marital status and average monthly income. However, there were significant differences in individualism-collectivism among the groups determined by age, occupation, educational background and rural or urban background.

This study has analyzed body size of adult women between 20~59 years old in 2010 conducted by Size Korea and the study method is as follow. (1) Distribution ratio of bust circumference per age and distribution ratio of differences of bust drops were analyzed. (2) Analysis of one-way design of experiment was carried out for 20 items of body sizes according to differences of bust drops with regard to age groups of 20 and 40 years old in consideration of tourists who are unspecified target and for the whole ages groups. (3) Comparison analysis of 20 items of body sizes per bust circumference and according to level of differences of bust drops was carried out and (4) t-test of the two groups based on the standard of 12.5 cm of the differences of bust drops was conducted and was analyzed. Tthe differences of bust drops below 10 cm were reduced according to ages. 12.5 cm was the most in the group of ages of 20s and under 7.5 cm was reduced as ages were higher. Body items according to the differences of bust drops per ages had meaningful differences between groups except (acromion height-axilla height), height and shoulder length for the group of ages of 20s and in the whole ages groups, there was meaningful difference between groups in all items except height and shoulder length. Comparisons according to the differences of bust drops per section of 5 cm of bust circumference showed meaningful differences between groups in general in items of BMI, bust point-bust point, neck circumference, bust circumference, underbust circumference, neck point to bust point and weight. As the result of comparing the two groups of the differences of bust drops based on the standard of 12.5 cm, all had meaningful differences except stature and shoulder length.
