자기 공명 영상(MRI)은 인간의 신경계 장애에서 뇌 구조의 변화를 검사하는 중요한 기술이다. 뇌 발달은 매우 복잡한 과정이며, 신경 생성과 유전자 프로그램의 영향을 받게 된다. 나이가 들어감에 따라 뇌의 다양한 구조 영역이 변화하면서 뇌 질환 형성에 기여하게 되며, 건강한 뇌의 발달에 영향을 미치는 다양한 변수 중 성별은 가장 큰 영향을 주는 요인 중 하나이다. 영상 데이터는 FSL(FMRIB software library)에서 제공하는 SIENAX, FIRST, 정점분석(Vertex Analysis)과 같은 다양한 프로그램을 통해 분석이 수행되었다. 우리의 결과는 특정 연령대의 피질하부영역에서 유의한 성별 관련 차이가 관찰되었음을 보여주고 있다. 성별과 볼륨간의 이러한 변화 정도 차이의 크기는 조사 된 영역에 따라 다르게 나타나고 있다. 이 연구에서 우리는 각 성별간 피질하부영역의 구조 분석을 위해 고해상도 3T MRI를 사용하였다. 또한, 정점 분석은 각 성별간의 피질 구조에서 체적 차이를 시각화하는데 사용되었다. 이 연구는 70대 그룹으로 제한되어 있으며, 향후 더 넓은 연령대를 대상으로 추가 연구가 필요하다.

This study classifies vanity into groups, analyzes age differences and categorizes price attitudes toward apparel products. Questionnaires were administered to 461 college students living in Daegu City and Kyungbok province. Data were collected using frequency, factor analysis, cluster analysis, correlation analysis, regression analysis, ANOVA, Duncan-test, and t-test. The findings were as follows. College student vanity was classified into three groups of appearance/ achievement pride, low vanity, and appearance/achievement concern. Vanity showed a significant correlation with sub-variables of age difference and price attitude towards apparel products. Appearance pride and achievement concern (sub-variables of vanity) had a significant effect on the conspicuous of price attitude toward apparel products. Appearance pride and Appearance concern (sub-variables of vanity) had a significant effect on information of price attitude toward apparel products. Gender of college students showed a distinction insub-variables of vanity factors such as appearance concern and price attitude toward apparel products such as information, quality, and using coupons. Male students were distinct in look and health as well as age differences by group; female students were distinct in age perception differences (a sub-variable of age difference).

Higher bone mineral density (BMD) at a young age, calcium intake, and exercise are important for prevention of osteoporosis later in life. We examined familial effects of BMD between mothers and children and adolescents aged 8-19 in Cheonan, Korea and the relationships between BMD and lifestyle parameters, including: food and nutrient intake and exercise. For daughters and sons, significant differences in BMD were observed at the three bone sites (total femur, femur neck, and lumbar spine) according to age, gender, body mass index, exercise, and milk consumption, compared to the reference value for each classification category. Mean differences in children's BMD were observed according to maternal BMD. Energy and calcium intake were lower in both children and mothers in comparison to the estimated daily energy requirement; however, their protein intake was much greater than the daily recommended intake. After adjusting for age and gender and for mother's age, body mass index, and total calorie intake, results of the food frequency test showed an association of a higher intake of meat, meat products, milk and milk products with greater BMD of total femur, femur neck, and lumbar spine of children. In addition, exercise was positively associated with higher BMD. Regression analysis showed a positive association of BMD with age, male gender, exercise, and mother's BMD. In conclusion, after adjustment for environmental parameters, maternal BMD had a positive influence on BMD in daughters and sons. This finding suggests that parents need to check their BMD in order to determine whether their children are at increased risk of low BMD.

The purpose of this study was to analyze the statistical differences and the correlation between eco-friendly attitudes and clothing selection criteria according to gender and age. 150 people in their 20s to 50s were surveyed for this study. The results were as follows. The factors to eco-friendly attitudes were drawn as seven factors. The difference analysis result for eco-friendly attitude according to gender and age showed a significant difference. The results of factor analysis showed that there were four factors in clothing selection criteria. The difference analysis result of clothing selection criteria according to gender showed a significant difference. The analysis results for the effect of eco-friendly attitude on clothing selection criteria showed that the eco-friendly group recognized health and eco-friendly property as more important clothing selection criteria, but the non-eco-friendly group recognized aesthetic as more important one. The result of this study will help product planners in the clothing product development and the market segmentation according to eco-friendly attitude.

Purpose: The aim of this study was to investigate gender differences in risk factors and sleep, depression, and mobility of Korean elderly with and without low back pain and sciatica. Methods: Data were derived from the 2011 Korean National Survey on Older Adults. Participants included 10,674 community-dwelling elderly. The group of elderly subjects with low back pain and sciatica and the group of elderly subjects without low back pain and sciatica were compared according to gender. Result: Age, monthly income, exercise, arthritis, osteoporosis, and providing caring support were significant risk factors for low back pain and sciatica in elderly male subjects. On the other hand, monthly income, living arrangement, arthritis, osteoporosis, providing caring support, and television watching time were significant risk factors in elderly female subjects. Significant differences in depression and mobility according to low back pain and sciatica were observed in both genders. Conclusion: Risk factors for low back pain and sciatica in elderly differed according to gender. Low back pain and sciatica showed an association with depression and mobility. These findings should be considered in planning for nursing intervention for low back pain and sciatica.

For an empirical study, 405 questionnaires were answered by respondents in their 20s and 30s with internet clothing purchase deferral experience. Data were analyzed using: SPSS for Windows 12.0 and descriptive statistics, reliability analysis, factor analysis, $X^2$-test, and regression analysis. The results of this study were as follows. First, the order of items with many purchase deferrals in internet clothing shopping were casual T-shirt>casual skirts>pants, one-piece>suits>sportswear>blouse/shirts and 58.3% of purchase deferrals happened when the price was below \50,000. Second, the significant differences in products, prices, and shopping malls for purchase deferrals were identified according to consumer demographics. There were significant differences in clothing items according to gender, age, marriage, and education; however, there were significant differences only according to gender in terms of price. There were significant differences according to gender, age, marriage, education, and income in terms of the used shopping malls. Third, for the analysis of the influence of diverse factors that can affect purchase deferrals for internet clothing shopping, the more information search, purchase deferral habits, perceived risks, and deficiency in shopping mall supply conditions were when higher purchase deferrals occurred. For a strong competitive online market, this study can help internet clothing shopping mall entrepreneurs manage products and customers by analyzing the lists of purchase deferrals indicated in "cart" and by administrating the influential factors for purchase deferral.

The purpose of the present study was to provide an assessment of the incidence of cancer of the larynx in Kazakhstan with especial attention to ethnicity and gender, as well as age. The retrospective design covered all new cases of laryngeal cancer in 11 years (1999-2009). The total number was 4,967 cases, 4,535 (91.3%) in males and 432 (8.7%) in women, with a gender ratio of 10.5:1. Patients of Kazakh (31.2%) and Russian (51.4%) ethnicity accounted for the vast majority (82.6%), with Russians predominating in both sexes, but particularly in females. Age peak in Kazakhs was 70 years and older ($14.6{\pm}0.70/0000$), and in Russians was 60-69 years ($21.6{\pm}1.30/0000$). In the dynamics, the rates had the tendency to decrease more markedly in Russian than Kazakh men, especially in the younger groups, while increase was noted in the youngest females of both ethnicities, but again greater in Russians, presumably reflecting change in underlying lifestyle factors.
