Purpose: Perceived barriers to exercise were investigated for adults. Method: A total 1266 subjects were selected by a quota sampling method with age, gender, and residence. Perceived barriers were categorized under 4 groups: knowledge, psychological, physical, and external factors. All 23 items of perceived barriers were responded on a dichotomous (yes/no) scale. Result: Mean number of perceived barriers was 4.61 and 87.9% subjects perceived at least one barrier which prevented involvement in exercise. External barriers ranked highest, followed in order by psychological, knowledge, and physical barriers. Most factors of perceived barriers were found to be different by age, gender, and residence, in that, the younger, female, living in Daejeon subjects were found to respond with more barriers than the older, male, living in Chungju or Seoul. Conclusion: Perceived barriers to exercise are differenct by age, gender, and residence. Therefore, it is recommended that age, gender, and residence of subjects must be considered in order to develop exercise programs and public campaigns.

The purpose of the study was to provide the basic information that is needed to build marketing strategies related to consumers' brand-switching, through investigation into sport shoe consumers' motivations for brand-switching, as determined by their age and gender. The study was implemented by means of a descriptive survey method using a questionnaire. The sample consisted of 534 consumers between the ages of 13 and 59, residing in the Seoul area. The survey for the study was conducted during the period of October 10 through December 5, in 2008. Descriptive statistics, t-test, ANOVA and Duncan's Test were employed for the analysis of data gathered. The results revealed that there are differences with regard to the degree that the functional/aesthetic factors of sport shoes contribute to the motivation for brand-switching, when assessed with respect to the age and gender of consumers. The contributory degrees of situational factors and social/emotional curiosity factors of consumers are also different with regard to the motivation for brand-switching behavior of sport shoe consumers in accordance with their age and gender. Therefore, marketing strategies related to brand-switching behavior will be more effective when they are differentiated according to the target age and gender, even with respect to the same type of product, such as sport shoes.

This study was carried out to investigate the relationship of the cadmium and lead levels in blood by age, gender and smoking status among 181 students in Gyeongnam province from June 2005 to July 2006. The cadmium and lead levels in blood was analyzed by atomic absorption spectrophotometer. Subjects were classified for the investigation according to smoking status as smokers and nonsmokers, age and gender. Mean blood cadmium level in male and female was $1.65{\mu}g/dl,\;1.10{\mu}g/dl$ respectively. Male was significantly higher than that of female. Blood cadmium levels in heavy smokers ($11{\sim}20\;ea/day$) and light smokers ($1{\sim}10\;ea/day$) were $2.34{\mu}g/dl,\;1.10{\mu}g/dl$ respectively. Heavy smokers were significantly higher than those of light smokers. In the comparison of age, gender and smoking status in blood Lead levels were no significant differences. In conclusion, heavy smoking was the most significant risk factor to increase blood cadmium levels. The further study will need analysis of the other factors related to the elevation of the cadmium and lead levels.

The problem of classifying of age, gender, and race images still poses challenges. Despite deep and machine learning strides, convolutional neural networks (CNNs) remain pivotal in addressing these issues. This paper introduces a novel CNN-based approach for accurate and efficient age, gender, and race classification. Leveraging CNNs with residual blocks, our method enhances learning while minimizing computational complexity. The model effectively captures low-level and high-level features, yielding improved classification accuracy. Evaluation of the diverse 'fair face' dataset shows our model achieving 56.3%, 94.6%, and 58.4% accuracy for age, gender, and race, respectively.

Formant is one of the essential vocal features for research of voice production, recognition and synthesis. Numerous studies were established on foreign languages including English vowels. However, studies related to Korean were done with a limited number of voice data. In this study, we compare four formants according to age and gender using a large number of Korean monophthongs. A total of 2614 Korean speakers participated in our experiments. We summarize statistical results by mean and standard deviation for each formant of five monophthongs. The results show a notable difference in each age and gender group. A quantitative study based on a large dataset is suggested for future studies on Korean speech sounds.

Purpose: This study was done to identify the relationship between gender-role stereotypes, sexual assault awareness and permissible limits in the college students. Methods: With a structured survey, a sample of 756 college students who agreed to participate in the study completed a self-administered questionnaire. Results: The result showed that gender-role stereotypes differed significantly depending on gender and age, while awareness of sexual assault differed significantly depending on gender, age, and location of residence. The permissible limits in sexual assault differed significantly according to gender, relationship with parents, and location of residence. There were significant relationships among awareness of sexual assault, gender-role stereotypes, and permissible limits of sexual assault. Conclusion: The result will provide preliminary data and strategies to develop sexual assault prevention programs.

This study was to find out children's Negotiation Levels(NLs) according to their age and gender. The subjects for this study were 143 children of 7, 9, 12 years. Two children dyads participated in the experimental play situation with Rokenbok Electronic Toy Systems. The NLs in children's interactive dialogue & actions were scored with Stone, Robinson & Taylor(1980)'s 'Negotiation of Task Completion Coding Manual'. They were coded into Level 0(no interaction), Level l(one way interaction), Level 2(reciprocally interaction), Level 3(mutual or cooperative interaction). The results were as follows; 1) 12-year-old children negotiated with higher level than 7-and 9-year old children 2) Boys' NLs average were higher than girls'. These results imply that 1) the fluctuation of NLs in childhood, especially around 10 years, should be interpreted carefully, 2) various measuring kits for negotiation should be developed considering children's characteristics, such as age, gender etc.

The present study investigated whether there are differences in articulation rate by gender, age, and individual speakers in a spontaneous speech corpus produced by 40 Seoul Korean speakers. This study measured their articulation rates using a second-per-syllable metric and a syllable-per-second metric. The findings are as follows. First, in spontaneous Seoul Korean speech, there was a gender difference in articulation rates only in age group 10-19, among whom men tended to speak faster than women. Second, individual speakers showed variability in their rates of articulation. The tendency for some speakers to speak faster than others was variable. Finally, there were metric differences in articulation rate. That is, regarding the coefficients of variation, the values of the second-per-syllable metric were much higher than those for the syllable-per-second metric. The articulation rate for the syllable-per-second metric tended to be more distinct among individual speakers. The present results imply that data gathered in a corpus of Seoul Korean spontaneous speech may reflect speaker-specific differences in articulatory movements.

It was assumed that the effect of estrogen on wound healing would be variable according to patient's gender and age since estrogen is a sex steroid. This study was designed to determine the variability of the effect of estrogen on proliferation of human dermal fibroblasts and collagen synthesis which are most important in wound healing considering patient's gender and age. Fibroblasts were isolated from the dermis of female patients in premenstrual, menstrual, or postmenopausal age group and that of male patients. The isolated fibroblasts were cultivated in the presence of estrogen($1.0{\mu}g/ml$). The cells were seeded at $5.0{\times}10^3cell/well$ in Dulbecco's Modified Eagle's Medium/Ham's F-12 nutrient including 5% fetal bovine serum in 96-well plates. The cells were incubated for 3 days. For fibroblast proliferation MTT assay method was used. To measure the production of collagen, the collagen type I carboxy- terminal propeptide enzyme immunoassay was carried out. Estrogen stimulated the proliferation of fibroblasts in female patients, but not in male patients. The greatest cell proliferation and collagen synthesis was seen at women in menstrual and postmenopausal age. These results demonstrated that effects of estrogen on dermal fibroblast proliferation and collagen synthesis were variable with gender and age.
