The purpose of this study was to investigate 1) the effects of clothing styles on impression formation of middle and high school students and 2) the differences in impression in relation to perceiver variablex(sex, age, residence). The sample consisted of 60 subjects in each of 8 perceiver groups according to sex, age and residence. Stimuli consisted of 10 color photographs of male and female adolescent wearing each of 5 clothing styles respectively. Questionnaires consisted of 43 seven-point semantic differential scales measuring perceivers responses to the stimuli, open-ended Question and perceiver’s clothing style preference. Responses to the semantic differential scale were factor analyzed and 4 factors - Self-confidence/refinement, Sincerity, Intelligence, and Sociability - were emerged to account for the structure of the impression of the male stimuli. Five factors - Sincerity, Refinement, Self-confidence, Sociability, Intellience - were emerged in case of female stimuli. One-way ANOVA results showed that clothing styles had the effects on all the factors of impression except Sincerity. From the reset analyzing the effects of perceiver variables on impressions, age had the effects in all the clothing styles, sex had the effects in 6 clothing styles, and residence in 5 clothing styles. Clothing style 5(male stimuli) and style 10(female stimuli) were the most preferred clothing style in all the subject groups.

Purpose: This study compared health behaviors and health-related clinical characteristics between individuals with normal glucose levels without diabetes and those with undiagnosed diabetes. Factors that were associated with undiagnosed diabetes were identified by sex. Methods: This was an observational study with a cross-sectional design based on data from the eighth Korea National Health and Nutrition Examination Survey, which used a stratified, multi-stage, cluster-sampling design to obtain a nationally representative sample. Multiple logistic regression analysis was employed to compute the odds ratios of health behaviors and clinical characteristics to identify risk factors for undiagnosed diabetes. Results: The overall prevalence of undiagnosed diabetes was 5.2% (weighted %, n = 700, p < .001). Among individuals with undiagnosed diabetes, 58.3% were men. Univariate logistic regression for undiagnosed diabetes identified sex, age, house income, educational level, and triglycerides as influencing factors. In multiple logistic regression by sex, the factors associated with undiagnosed diabetes in men were age, perceived health status, a diagnosis of angina, and triglycerides. Conclusion: Strategies should be targeted to improve health behaviors and clinical characteristics for specific age groups, men in bad perceived health status, women with high systolic blood pressure, and high triglycerides. Moreover, healthcare providers should understand the barriers to health behaviors and health-related quality of life to effectively deliver healthcare services.

The aim of this study was to analyze the effects on growth and muscle development during the growing period of the sex-linked dwarf gene in the background of a Taiwan Country chicken strain, L2, selected for egg production. Eight crossbred males, heterozygous for the DW*DW mutation, were each backcrossed to six females of the L2 strain to produce two genotypes of BC females, either normal (DW*N+/-) or dwarf (DW*DW/-). The experiment included 251 normal and 207 dwarf pullets. The effect of the dwarf gene on body weight and shank length was highly significant from 2 weeks of age. The reduction of body weight by the dwarf gene reached 34.8% and 37.4% as compared to normal sibs at 16 and 20 weeks of age, respectively. Parameters of the growth curve were estimated: the age at inflection (TI) was higher in normal pullets (66.9 days) than in dwarf pullets (61.2 days). A significant effect of the dwarf gene on single muscle fiber cross-section area was found from 12 weeks of age onwards, whereas the dwarf gene had no effect on the total number of muscle fibers. Comparing the effect of the dwarf gene on shank length at different ages revealed an earlier effect on skeleton growth, observed from 2 weeks of age, than on muscle development, which was affected from 8 to 12 weeks of age.

The purpose of this study was to investigate the sexual knowledge and the needs of sex education for college students in order to develop sex education program. The data were collected from 271 students attedning K community college in Chungcheongbuk-do from November, 29 to December 3, 1999, using a self-administered questionnaire. Sexual knowledge in this study include 4 areas such as sexual physiology, contraceptive methods, venereal disease. and reproductive physiology. The results were as follows : 1. The mean score of the knowledge in sex was 15.42 out of 29, which is very low. Of the four areas of the knowledge, the students showed the lowest score in contraceptive methods. Woman students had significantly higher score in reproductive physiology than man students. 2. Seventy nine percent of the students felt the need for sex education being given by their college. Most students wanted to obtain sex education through special lectures $(55.7\%)$ or regular curriculum$(29.2\%)$, Those specialists in sex education were most prefered. with regard to the contents of sex education, sexual psychology was most frequently indicated followed by contraceptive methods, pregnancy, satisfy ways of sexual drive. About forty two percent of the students thought preschool age as the adequate stage for beginning sex education. 3. Sexual knowledge was statistically significant in terms of grade. major. and dwelling state.

This study analyzed the epidemiological trends of sexually transmitted infections (STIs) according to age and sex among individuals aged 50 years or older in South Korea from September 2018 to December 2020. We found that the positivity rate for Gardnerella vaginalis was the highest in the study group, followed by the positivity rate for Ureaplasma parvum (UP). Interestingly, the positivity rates for Mycoplasma hominis and UP were higher in female participants than in male participants. The positivity rate for Treponema pallidum was very low in the female participants. During the study period, the positivity rate for herpes simplex virus 2 increased in the female participants, while the positivity rate for Candida increased in the male participants. These results show that the STI positivity rate varies according to age and sex, and a difference was observed in the average age of positive participants according to the type of STIs. We found a clear pattern of infection in the elderly population and according to sex. Our findings are expected to be used as baseline data for future research, education, and prevention of STIs in the elderly population.

The haematological profiles of camel calves of either sex were monitored at monthly intervals between 1-12 months of age. RBC, Hb and PCV increased with age for several months, with corresponding increases in MCH and MCHC, and a relative reduction in MCV. WBC and lymphocyte counts were highest at the age of 1 month, fell progressively during the following 6 months, and stabilized thereafter. Neutrophils were also highest at the age of one month and decreased slowly with advancing age. Eosinophils, monocytes and basophils fluctuated only from month to month. Age effect was significant for WBC, lymphocytes and neutrophils, and all the erythrocytic parameters, except MCV. Sex effect was significant for Hb and eosinophils.

The aim of this study was to examine the effect of differences in age and sex on vestibular evoked myogenic potentials (VEMP), particularly in normal participants. Briefly, the VEMP is a response elicited by loud clicks or tone bursts recorded from the tonically contracted sternocleidomastoid muscle. A total of 72 participants were divided into 6 groups according to their age and sex (20~30/F, 20~30/M, 40~50/F, 40~50/M, ${\geq}60/F$, ${\geq}60/M$). We got the data of latency, amplitude, and asymmetry index of the amplitude(ASI) from them. As a result of this study, there are variations in VEMP amplitudes and ASI depending on the muscle tension and the intensity of stimuli. In contrast, the latency of the response is usually less varied and does not differ significantly.

This study was described the movement patterns when rising from supine to erect stance. Two hundred eighty seven subjects, ranging in age from 6 year to 28 were filmed while rising from a supine position. Movement Patterns were classified using categorical descriptions of the action of three body regions-the upper and lower extremity, head-trunk region. This study was designed to determine whether within the rising task the movement patterns of different regions of the body vary with age level and sex. The incidence of each movement pattern was calculated and graphed with respect to age level and sex. The most common form of rising for subject in the 6, 7 year mate group usually involved push and reach pattern with upper extremity, half kneel pattern with lower extremity, partial rotation pattern with head-trunk. In the 6, 7 year female group usually involved symmetrical push pattern with upper extremity, symmetrical squat with balance step pattern with lower extremity, symmetrical interrupted by rotation pattern with head - trunk. In the teenage and twenties both sex group usually involved symmetrical push pattern with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern with head-trunk.

Purpose: The purpose of this study was to determine the important factors on juvenile delinquency and to examine relationships between sex, age, the family environment, the personality of adolescents, smoking, and juvenile delinquency. Methods: Data collection was done through questionnaire surveys. The subjects for this study consisted of 1,948 adolescents delinquents : 784, students : 1,164 in Korea, using proportional stratified random sampling method. Statistical methods employed were chi-square, t-test and path analysis. Results: The results of this study were as follows : 1. The delinquent adolescents were reared in a more dysfunctional family environment, and had a higher maladaptive personality than the other student adolescents. 2. The delinquent adolescents showed the larger amount of smoking than the student adolescents. The cause of increased smoking tendency among delinquents simply were 'for social relation', 'for diversion', 'for nicotine addiction', whereas 'for tension relieving' among non-delinquent adolescents. 3. The most powerful contributors on delinquent behavior were antisocial personality tendencies, smoking, sex, strength of parent- child relationships, and the age of the adolescents in this order. Conclusions: Our cross-sectional findings indicate that smoking was one of the most powerful contributing variables to delinquent behavior, but family environment, personality, sex and age of adolescents were also proved to be strong exogenous variables to smoking in adolescents.
