This article explores the relationship between the gender composition of scientific research teams and scientists' individual performance. The gender composition of research teams is an important feature of workplace settings and influences the way people interact and communicate; however, previous research has not directly examined its relationship with scientists' individual performance. Drawing on data collected on university faculties in China in 2016, this article tests several hypotheses about individual's performance in teams with different gender compositions. The results show that team gender composition has a clear gendered effect on scientists' individual performance. The effects of tokenism for women in men-majority teams is proven, but men in women-majority teams appear to be unaffected by tokenism. Moreover, the theories claiming that homogenous teams are more conducive to better individual performance than mixed teams are supported for men but not for women. The findings of this research suggest that recruiting more women into the scientific workforce may improve their performance and thereby help diminish the gender gap in performance. It also indicates that the Chinese preferential policies towards women in science formulated in recent years have had positive impacts. However, considering that more than half of the researchers in the survey are working in men-majority teams, the task of narrowing the gender gap in performance remains a challenge. Further work is needed to explore the tensions and benefits of working with the opposite gender.

This study examined the gender differences' composition affecting poverty in Busan and possible strategies for overcoming poverty. It was found that there were both common and differentiating points regarding gender in poverty situations. Poverty stricken women, tended to be older and less educated than their male counterparts. In the case of men, they were more likely to have physical disabilities than women. There were more women compared to men when regarding divorce and separation due to the death of a spouse as contributing to poverty. Women estimated that it was much easier to overcome their poverty situation as they were younger and had more income. However, there were gender differences in regard to actual re-establishment. For men, education level was the most important variable for overcoming poverty while for women; the existence of a spouse was the important variable. These results suggest that a gender sensitive approach is necessary to address and find solutions to the poverty issue. Therefore, it is hoped that this study's findings may provide valuable information and support for changes to the welfare policy.

To achieve effective learning, knowledge must be shared and developed through interaction with peer learners. Therefore, science education emphasizes small group inquiry activities that solves tasks through the interaction of members. The effect of small group inquiry activities depends on how to compose small groups. The way in which a group is composed is a very important factor for improving interaction. In particular, it has been reported that the gender of peer is a very important factor in the interaction between students in the composition of small groups. Meanwhile, studies are being conducted on the types and stability of verbal interactions in small group inquiry activities using social network analysis. The purpose of this study is to analyze the types and stability of verbal interaction types and stability according to gender-grouping in elementary school students' small group activities using social network analysis. To this end, 60 5th graders in elementary school were conducted with different gender in the composition of the group of male, female and mixed-gender students. The study found that the composition of a group by gender had little impact on the type or stability of verbal interaction. However, the frequency of verbal interactions was higher in mixed-gender groups than in other groups. Through this process, the gender-grouping in elementary school students' small group activities suggests a mixed-gender group.

The present study was designed to investigate health-related life habits, food preference, body composition for proper dietary habits, health promotion of communities in Incheon area. The effects of personal characteristics and health-related life habits such as gender, age, having breakfast, smoking, drinking, and exercise were analyzed using a surveying. 961 community subjects (262 males and 699 females) were investigated using a questionnaire and Inbody. Data were analyzed by descriptive statistics, chi squared test, and one-way ANOVA (analysis of variation) with SPSS/WIN 21.0. The result of gender distribution showed there were 262 males and 699 females, and with respect to the effect of gender on health-related life habits, smoking, drinking, and exercise showed significant differences (p < 0.05), whereas having breakfast was not significantly difference (p>0.05). Therefore, the present provide evidence of a relationship between health-related life habits and gender. Regarding the effect of BMI on health-related life habits, exercise showed significant differences (p < 0.05), whereas smoking, drinking, and having breakfast were not significantly difference (p>0.05). Thus, the present study also provides evidence of a relationship between health-related life habits and BMI. Our analysis shows that food preference and body composition were significant different from health-related life habits such as smoking, drinking, exercise, and having breakfast (p < 0.05). Our analysis showed that body composition was significant differences from health related habits such as smoking, drinking, exercise, and breakfast (p < 0.05).

The aim of this review is to address some characteristics that influence meat quality. Genetic groups, nutrition, finishing systems and gender are the major factors that change carcass characteristics, chemical composition and fatty acid profile. Genetic groups that have zebu genes in their composition show higher hot carcass dressing than genetic groups without zebu genes. Genetic groups that have European breeds in their composition have higher marbling scores. On the other hand, genetic groups that have zebu breeds show low marbling scores. Bulls finished in feedlots present higher final weight than steers, cull cows and heifers. Fat thickness is one of the principal parameters that are affected by different gender. Cull cows (4.72 mm) and heifers (4.00 mm) present higher values than bulls (1.75 mm) and steers (2.81 mm). The major effects observed by different systems of termination are fat thickness and marbling. Crude protein presents variation due to nutrition. Nutrition influences variation of fatty acid profile. Genetic groups also influence fatty acid profile. Genetic groups that have zebu genes in their composition show high percentage of PUFA. The major class of fatty acids that is changed with nutrition is PUFA. The better ratios of PUFA/SFA and n-6/n-3 are found in Longissimus muscle of animals finished in pasture systems.

We examined the prevalence of sarcopenia and age-related changes in body composition in Korean older persons. Community dwelling 77 men and 65 women($60{\sim}88\;yr$) were recruited for this study. Fat-free mass and the percent body fat were determined using bioelectrical impedance analysis. Isometric grip strength was measurement using grip strength dynamometer. Serum levels of fasting glucose, total cholesterol, HDL-cholesterol, and triglyceride were assayed. The prevalence of sarcopenia was found to increase with aging (men in their sixties 82.6%, seventies 96.6% and eighties 100%, and women in their sixties 47.4%, seventies 63%). In both gender groups, handgrip strength was inversely correlated with age and positively correlated with height, lean mass, and fat free mass. Better handgrip strength was related with higher weight in the men and with lower heart rate in the women. Fat free mass, age, and gender were found to be independent factors significantly associated with handgrip strength in the multivariate analysis. In summary, results of the present study suggest that handgrip strength is well associated with age, gender, and fat free mass and the prevalence of sarcopenia is increased with age and is exceeded by 40% among Korean persons older than 60 years.

The effect of slaughter weight and gender on fatty acid composition of homogenised rib samples of Hungarian Simmental (HS) and Holstein-Friesian (HF) cattle breeds was investigated. In the first experiment 22 Hungarian Simmental and 18 Holstein-Friesian cattle's meat, in the second experiment 15 females and 12 males Holstein-Friesian cattle's meat was analysed on fatty acid content. Saturated and mono- or polyunsaturated fatty acid profile did not seem to vary either by breed or by slaughter weight categories. The effect of gender, however, proved to be significant in influencing the quantity of polyunsaturated fatty acids, including linoleic and linolenic acids, as well as polyunsaturated fatty/saturated fatty acids (PUFA/SAFA) ratio. The amount of polyunsaturated fatty acids (PUFA) was higher in males than in females. Negative correlation was established between the quantity of PUFA and the amount of adipose tissue in rib samples.

This study was designed to investigate the dietary habits, life habits, physical symptoms, and body composition of male and female students attending college in incheon, based on which to encourage proper dietary habits among and enhance the physical and psychological health of college students. The effects of personal characteristics (such as gender, grade level, residence type, means of transportation), health relative life habits (exercise, smoking and alcohol consumption), dietary habits, physical symptoms and body composition measurement were analyzed by using the questionnaire and Inbody. The subject pool was composed of 96 male and 149 female students. Smoking, drinking, exercise, and fruit intake showed significant differences between the genders (p<0.05), whereas meat intake was not significantly different (p>0.05). Differences on dietary habits and the intake of fruit showed significant differences (p<0.05) between the genders. Especially, more female than male students showed a higher frequency of fruit intake. Physical symptoms such as headache, common cold, dizziness, easy fatigue, poor concentration, indigestion and constipation showed significant differences (p<0.05) between the genders, whereas stomatitis, anorexia and pale face were not significantly different (p>0.05). Differences between the genders on body composition, height, weight, BMI, muscle soft lean mass, body fat mass, skeletal muscle mass and waist-hip ratio were also significantly different (p<0.05). The correlation analysis of college students by gender was negative between intake of milk and physical symptoms (p<0.01), whereas intake of cooked food and physical symptoms showed a positive correlation (p<0.01, p<0.05).
