The aim of this study was to establish the basic data on anthropometric characteristics of Korean farmers in a sitting posture. 533 Korean farmers(Male: 236persons, Female: 297persons) volunteered for this study from 8 different provinces nationwide in 2010. Subjects were classified according to their sex and categorized into 4 age groups from 40s to 70s and over. Statistical tests such as descriptive analysis, independent t-test, one-way and two-way ANOVA were conducted to analyze the data. The results were as follows: Korean farmers generally edged toward obesity. The older the farmers were, the smaller their body sizes were, but fatter in the abdominal areas. There were significant differences on the waist-related measurement items between farmers and the public. The farmers' waist-related sizes were larger than that of the public of all age groups in the male group, but only the forties age group in the female group. It tended to differ according to sex and age groups that we analyzed from the measurement values on other items between farmers and the public.

Contraception, abortion and ejection are contents they poorly informed of. 3. As a result of the examination on experienede of sex education, 83% of men and 100% of women have experienced sex, education, but their degreeof satisfaction to it is very low. And 49% of the whole is dissatisfactory to it. There is some difference between male and female students.(p=0.000) That result translates that female studeuts are educated on sex tjhrough more systematic subjects than male ones. In addition, it turns out that teenagers get most information on sex through friends, seniors, and mass media such as videos, TV and radios. Correct and systematic sex education is need because wrong information on sex culd be taught and bring them to misbehave. 4. 87.5% of the respondents answer that sex education is necessary, so that degree of necessity for sex education, turns out to be very high. Also the main subject that should perform sex education is in the order of school(50%), Society(24.5), home(18.5%). They respond that most appropriated period for the beginning of sex education is about elementary school age(43%), and 34% believes it to be put ahcad of elementary school age. Anurse teacher accounts for 54% for the main subject that addresses sex education, to male students visit teachers are most favored for 50%. As a result of those, it could be concluded that most high school students want sex education from responsible persons who have systematic and professional knowledge on sex. 5. In order to perform proper sex education by the above results, better educational effects are obtained when characteristics and natures of teenagers are known and most wanted knowledge by them is taught in priority in times of planning sex education. Besides, the contents of sex education suitable for each school should be planned before elementary school age and sex education should be performed in accordance with students' demand. In addition, sex education should be attentively performed by home, all organizations of society as well as school. Therefore, sex education will play a great role in making teenagers reestablish their conception on sex when the traditional and moral value systems of our country and the new value systems which are being formed under the influence of the western culture are in harmony.

Background: Cystic fibrosis (CF) is an autosomal recessive disorder with several clinical presentations. This study was undertaken in the Azeri Turkish population in Iran, to investigate gender differences in the age at onset and diagnosis, age of death, and duration of illness of CF. Methods: The data of 331 CF patients from 2001 to 2015 was surveyed. Parameters including age, sex, ${\Delta}F508$ mutation, age at onset, age at diagnosis, age of death and clinical presentations were evaluated for both sexes, using descriptive analysis. The association of gender with these variables was studied using logistic regression, chi-square test and Mann-Whitney U test by SPSS version 18. Odds ratio with a confidence interval of 95% and $p{\leq}0.05$ was considered statistically significant. Results: The study included 191 males (57.7%) and 140 females (42.3%), all showing statistically significant difference (p<0.001). Age duration differed between genders. Male and female patients were further under 9 and 4 years, respectively. The occurrence of ${\Delta}F508$ mutation was 0.51 times more in females than in males. Age, diagnosis and sex were closely associated: males were diagnosed at a significantly later age than females (p=0.05). While this compression performed based on clinical presentations, males with respiratory disease had a later median age at diagnosis than females at lifespan (p=0.001). The risk of infertility in males was approximately two times greater than in females (p=0.02). Conclusion: These findings indicate gender differences in CF patients. Future studies are needed to establish other differences and evaluate the causes for the gender variations.

Osteoma is benign tumor composed of mature compact or cancellous bone. Generally it is classified as periosteal(or peripheral) osteoma and endosteal(or central) osteoma by its origin. Clinically, periosteal osteoma on forehead is usually asymptomatic. From March 2002 to February 2005, We experienced 20 patients(23 cases) of histologically confirmed frontal osteoma. 20 patients are classified as sex, age, the number of osteoma, size, location and shape. Out of 20 patients, 16 were female and 4 were male in sex and mean age was 46. 18 patients have only one lesion but one patient has two lesions and another patient has three lesions. The size of osteoma varied from $7{\times}5{\times}3mm$ to $16{\times}14{\times}6mm$ and mean size is $12{\times}10{\times}5mm$. All osteomas were located at midline of forehead and shape of attachment was all sessile type. Surgical excision was superficial ostectomy through direct cutaneous incision or endoscopic approach. we obtained satisfactory result without specific complication.

High fructose diet is associated with the global metabolic syndrome (MtS) pandemic. MtS develops in early life, depending on prenatal and postnatal nutritional status. We hypothesized that ovariectomy increases the chances of developing MtS in adult offspring following high fructose intake by the mother. Pregnant C57BL/6J mouse dams drank water with or without 20% fructose during pregnancy and lactation. After weaning, the pups were fed regular chow. The offspring were evaluated until they were 7 months of age after the mice in each group, both sexes, were gonadectomized at 4 weeks of age. The offspring (both sexes) of the dams who had high fructose intake developed MtS. In the offspring of dams who drank tap water, orchiectomy increased the body weight gain and body fat accumulation, while ovariectomy increased the body fat accumulation as compared to the sham controls. In the offspring of dams with high fructose intake, orchiectomy decreased the body weight gain, body fat accumulation, visceral adiposity, and glucose intolerance, while ovariectomy exacerbated all of them as compared to the sham operations. These data indicate that ovariectomy encourages the development of MtS in adult offspring after maternal high fructose intake, while orchiectomy prevents the development of MtS. The sex difference indicates that male and female sex hormones play contradictory roles in the development of MtS.

Different aspects of morality, namely, moral belief, moral judgement and moral behavior have been studied seperately. This study examined the development of these three aspects of morality in relation to internal attribution in one sample. A total of 371, third -and sixth- grade children from Masan city were responded to questionnaires on moral belief, moral judgement, and attibutional tendency. In addition, children's moral behavior was measured by the teachers' 5-item rating scale. As results, there were signigicant but low correlations among three components of morality. There were developmental differences in moral belief and moral judgement but there was no age difference in moral behavior. Compared to third graders, sixth graders were higher in moral judgement but lower in moral belief. Social experience as well as cognitive development on moral relativity could explain this paradoxical developmental trend in moral belief. There was a sex difference only on moral behavior : Girls were rated higher in moral behavior than boys. Internal attribution was significantly correlated with all three aspects of morality, .15 with moral belief, .45 with moral judgement, .14 with moral behavior, respectively. There was a significant developmental difference but no sex difference in attributional tendency: Sixth graders reported higher internal attribution than third graders. However, there was no developmental difference in correlations among internal attribution and three aspects of morality. Most importantly, internal attribution explained morality better than either age -or sex- variable. It was suggested that educational programs on morality need to focus on the internalization of it.

The purpose of this investigation was to study the hematological response of Saudi Arabian Baladi fowl to protein rearing regimens. Males and females were subjected to the following 4 protein rearing regimens: conventional, C; reverse protein, RP; 2 single-stage low protein, $SS_1$ and $SS_2$ using 15% and 12% CP diets, respectively. Regimen effect was highly significant ($$p{\leq_-}.01$$) on BW, PCY, TP and U-Ac and significant ($$p{\leq_-}.05$$) on TL. Serum chol levels were not affected by regimen. In general $SS_{2}$ birds showed the lowest values for all parameters studied, except for PCV. However, the differences were not significant in each case. Age and sex effects were highly significant ($$p{\leq_-}.01$$) for all parameters, however, the regimen X sex interaction was not significant except for PCV. Regimen X age interaction, on the other hand, was highly significant ($$p{\leq_-}.01$$) only for BW, TP and U-Ac concentrations. The data may suggest that low levels of protein in the rearing regimen is an important factor influencing levels of the blood parameters studied. The data also indicate a lack of clear relationship between hen-day egg production and the blood parameters studied.

Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.
