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.

The aim of this study was to investigate the variation in shape, size and area of the pharynx and adenoids, and to analyze the relationship between pharyngeal cavity and upper facial cranium which effected on morphology of those parts in Korean. Age changes and sex differences in those areas were comprised in this study. Materials included 272 lateral cephalograms, which were divided into 4 groups by age; (1) 7-year-old group consisted of 29 males and 30 females, (2) 12-year-old group consisted of 30 males and 30 females, (3) 17-year-old group consisted of 30 males and 40 females, (4) 20-year-old group consisted of 37 males and 46 females. In subjects each variable was measured and evaluated statistically introducing 17 reference points and 17 reference lines respectively. Conclusions from this study were as follows. 1. Linear measurements of the bony nasopharynx revealed that the depth and height were larger in male than those in female in 17 and 20-year-old groups. 2. Linear measurements of the upper facial cranium were larger in male than those in female in all age groups. 3. Angular measurements of the bony nasopharynx and upper facial cranium did not show, on an average, sex differences in each age group. 4. As regards area of the bony nasopharynx, it increased gradually with age in both sexes. And the area was greater in male than that in female in 17 and 20-year old groups. 5. There were sex differences in area of the adenoids of which the area was larger in male than that in female in 17 and 20-year-old groups. And the area reached a peak at 17-year-old group in male and at 12 year-old group in female. 6. Area of the pharyngeal cavity increased gradually with age in both sexes, but no sex differences were noted in each age group. 7. Rate of area of the adenoids to that of the pharyngeal cavity decreased continually with age, and no sex differences were noted in all age groups. 8. In amounts and its differences of the growth, there were sex differences in the posterior upper facial height, and were not in area of the bony nasopharynx, pharyngeal cavity and adenoids in each age group.

Objective: The aim of this study was to compare carcass traits, meat quality and sensory attributes in two different genotypes of geese according to age and sex. Methods: The experiment was carried out on 160 birds of two genotypes of geese: the Czech Goose (CG) breed and a Eskildsen Schwer (ES) hybrid. One-d-old goslings were divided into four groups according to genotype and sex. Two dates for slaughtering (at 8 and 16 wk of age of goslings) were undertaken. Results: The slaughter weight, cold carcass weight and dressing percentage were affected by all the studied factors, and significant interactions between age, genotype and sex were detected in the slaughter weight (p<0.001) and cold carcass weight (p = 0.004). The pH was not affected by any of studied factors, whereas in terms of meat colour parameters there were observed significant effects of age on $L^*$ and $b^*$ value and a significant effect of sex on $a^*$ value. The meat fat content was higher (p = 0.002) in ES. Higher score for overall acceptance of goose meat was recorded for ES at both ages compared to CG. Conclusion: ES had higher dressing percentage and better sensory attributes, whereas CG exceled in the favourable nutritional value of the meat.

Objective: Pain following the insertion of separators and archwires varies with age, sex, race, ethnicity, threshold, and health status. This study aimed to evaluate the characteristics of pain in orthodontic patients after the insertion of elastomeric separators, its effects on daily life, and its association with age and sex in a population not previously studied in this regard. Methods: A cross-sectional study of 130 patients undergoing orthodontic treatment included collecting data on demographics, pain experienced following the placement of separators, time of onset, duration, characteristics, change in dietary pattern or chewing side, intake of analgesics, and severity of pain on the Wong Baker's scale. The results are reported as counts and percentages. Associations between sex and age were evaluated using Pearson's chi-square test. Results: Among the 130 patients, 56.2% were 9-20 years old, 63.8% experienced pain following the insertion of separators, 22.9% had their first episode of pain at 4 hours, 56.6% experienced intermittent pain, and 37.3% experienced discomfort; 18.1% males and 81.9% females experienced pain following the insertion of separators. Pearson's chi-square test showed a significant association between pain and sex (P = 0.04). Most patients (37.3%) reported "hurts little more" for pain intensity on Wong Baker's scale and 21.7% reported all four quadrants as sites of pain. Conclusions: The pain experienced after separator insertion was associated with sex and age. Females experienced more pain than males and patients between the age range of 21 and 36 years suffered more pain during mastication than between 9 and 20 years old.

Vertebral left atrial size can be used as a radiographic tool to evaluate left atrial size in dogs. Vertebral left atrial size has been studied in dogs; however, few studies have been conducted on breed-specific differences in healthy dogs. To study the median vertebral left atrial size differences by breed and to investigate the association between age, sex, body condition score, thoracic depth-to-width ratio, and vertebral left atrial size. A total of 220 dogs of the following breeds: Maltese (n = 73), Beagle (n = 30), Poodle (n = 41), Shih-tzu (n = 44), and Mongrel (n = 32) were reviewed retrospectively. Sex, body weight, age, and body condition score of each dog were collected. Thoracic radiography was conducted for dorsoventral and right/left lateral views in all dogs to measure the vertebral heart score, vertebral left atrial size, and thoracic depth-to-width ratio. No significant differences in the median vertebral left atrial size were found among the breeds. There were no effects of sex, age, body condition score, and thoracic depth-to-width ratio on vertebral left atrial size. There was a significant positive correlation between the vertebral heart score and vertebral left atrial size. Breed, age, sex, and chest conformation did not correlate with vertebral left atrial size.

Thirty Holstein calves were used to determine effects of age, environment and sex on blood metabolite concentrations during 1 to 90 d of age. Calves were weaned at 75 d of age. Environmental effects are grouped by the difference in month at birth and site of feeding. Blood samples were obtained every 2 or 3 d. The mean metabolite concentration every 3 d was used for the statistical analysis. Dairy bodyweight gain was not affected by environmental group and sex effect. Concentrations of plasma glucose, nonesterified fatty acids (NEFA), triglyceride, total cholesterol and total ketone changed with growth. These developmental changes in metabolite levels would be caused by ruminal maturation with increment of grain intake. Levels of plasma urea nitrogen, glucose, NEFA, triglyceride and total cholesterol drastically changed during a few weeks after birth, indicating that the physiological state in calves greatly changed during that time. Effects of the environmental group and sex were significant in almost all metabolites. Temperature influenced plasma metabolite concentrations. The plasma metabolite concentrations were affected more intensely by heat stress in the infant period than in the neonatal period.

The purpose of this study was to investigate children's conceptions about gender and the relation between gender conceptions and preference for gender related tasks. 130 children were interviewed about gender and gender related tasks. Data were analyzed with the component model of gender schema. Results indicated that children's gender schema in the attitudes domain was significantly different with age in all components but not different with sex. The gender schema in the knowledge domain was significantly different with age in within component and between component links, and with sex in the gender label-component and within component links. The difference between the gender inhibitory score and gender facilitative score was significantly different with age, sex, and children's gender schema. The findings that gender schema influenced the children's preferences for gender related tasks suggests a theoretical rationale of gender schema theory.
