Purpose: Constipation is a common pediatric problem worldwide. This study aims to describe the clinical characteristics of pediatric constipation in south Jordan according to gender and age group. Methods: All patients with constipation managed at our pediatric gastroenterology service between September 2009 and December 2012 were included. Hospital charts were reviewed. Demographic data, clinical characteristics, and final diagnosis were recorded. Data were analyzed according to gender and the following age groups: infants, pre-school, school age, and adolescents. Results: During the study period, 126 patients were enrolled. The number (percentage) of patients according to age were the following infants: 43 (34.1%), pre-school: 55 (43.7%), school age: 25 (19.8%), and adolescents: 3 (2.4%). Males made up 54.8% of the study population. There were no statistical gender differences in any age group. The most common symptom in all age groups was dry, hard stool. Infrequent defecation was found in almost one-half of the patients. Fecal incontinence was more common in school-aged children compared to pre-school-aged children and adolescents. Abdominal pain was seen in almost 40% of the constipated children. Abdominal pain was more prevalent in girls and older children. Fecal mass in the rectum was the most common physical finding, with constipated boys exhibiting higher rates. Functional constipation was the most common etiology. Conclusion: Clinical characteristics of constipation in children vary according to age group and gender. Older children had less frequent bowel motions, a longer duration of symptoms, and a higher prevalence of long-standing constipation compilations (fecal incontinence and abdominal pain).

The primary goal of the present study was to explore more detailed evidence for the influence of aging and gender effects on the capability of Korean healthy, ears to generate DPOAEs. DPOAEs were examined in series of human subjects, with clinically nonnal hearing, ranging in age from 10 to 65 years. All 60 Koreans were divided into 6 age groups. Each age group included 10 participants, 5 females and 5 males. The gender effects on the difference between the absolute amplitude and noise floor value in DPOAEs did not exist. The difference increased as the frequency increased. The aging effects on the difference between the absolute amplitude and noise floor value in DPOAEs did exist. The difference increased as the frequency increased but orderly age effects could not be found. The principle finding was that, when compared between emissions in young and old ears, DPOAEs accurately tracked the systematic deterioration of high-frequency hearing in aging individuals. Such results support the need to reestablish the criterion for interpretation of DPOAEs in the elderly.

The purpose of this study was to exam the effects of gender-role identity on adolescents' self esteem, clothing behaviors and favorite clothing image, focusing on analysis by adolescent' sex and age variable. The research method was survey and the subjects were 447 male and female adolescents in Daejeon, Korea. The questionnaire consisted of 4 measurement instruments (gender-role identity, self-esteem, clothing behaviors, and favorite clothing image) and subject' demographic attributions. The data were analyzed by factor analysis, $X^2$ test, t-test, ANOVA(analysis of variance), Duncan's multiple range test, and Pearson's correlation analysis, using SPSS program. The results are as follows. First, adolescents' gender-role identity and self- esteem were different by age rather than sex. Middle school students were represented by undifferentiated type while high school students were represented by androgynous type, and high school students had higher self-esteem than middle school students. Second, four factors emerged on clothing behaviors(clothing interest & psychological dependence, ostentation, conformity, and comfort), and favorite clothing image(characteristic, neat, active, and romantic image). Third, gender-role identity had important effects on self esteem; androgynous type had higher self esteem than other gender-role identity type. Forth, self-esteem had significant relationship with clothing behaviors and favorite clothing image, and these relationships were different by adolescent' sex and age variable. Fifth, gender-role identity had important effects on clothing behaviors; and rogynous type had more clothing interest, ostentation and comfort than any other gender-role identity type. Sixth, gender-role identity had important effects on favorite clothing images; androgynous type pursued more various clothing images than any other gender-role identity type.

Objective: This study was performed to evaluate gender and age differences in hygienic behavior among the general population, focusing on hand-washing habits and the microbial load of hands. Methods: A self-administered questionnaire survey and a separate microbial examination were performed. The Pearson's correlation between hand-washing habits and microbial load was analyzed. Results: In the questionnaire survey on hand-washing habits, gender differences were found in hand-washing frequency, use of hand-washing agents, and hand drying methods (p<0.05). Age differences were found in numbers of washing parts of the hands and also in hand drying methods (p<0.05). Females showed better habits washing hands than did males, as did older people compared to younger. In the microbial examination of indicator bacteria on their hands, younger people tended to show a higher load of total aerobic bacteria than did the older, and females showed a higher load of total coliforms than did males (p<0.05). There were significant relationships between the load of total aerobic bacteria and hand-washing frequency, duration, and method of turning-off water (p<0.05). Conclusions: Although females were expected to show a better practice of hand-washing than were males based on the survey results, they showed a higher level of total coliforms in the hand examination. The older age group showed better hand-washing habits than did the younger age group and had less total aerobic bacteria on their hands. These inter-gender and age differences highlight the need for development and implementation of gender-and age-specific educational programs or campaigns.

The global trend for women's policy has selected gender mainstreaming to change unequal gender relation. The gender mainstreaming means that the gender perspective is integrated into all policy processes to accomplish gender equality. In other words, 'gender' should be considered as a basic factor such as classes, regions, and races when a policy is established and implemented. The government has implemented various gender mainstreaming policies to integrate gender perspectives. This study is to examine officials' perception about various gender mainstreaming policies. The survey was conducted for Daejeon city officials (699 men and 457 women). Officials' perception is very important, because it is an important means used as a tool in shaping and implementing policies. Variables such as gender, age, position, length of service, work place, etc. were chosen and the differences between variables were analyzed. The analysis showed that gender mainstreaming policies were perceived as ones only for women. Therefore, various education programs according to gender, age, position and length of service should be developed to improve the effectiveness of gender mainstreaming policies. In addition, education programs for officials to improve gender sensitiveness should be developed and expanded.

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.

The purpose of this study was to examine the developmental trends in children's gender-role flexibility across different areas of gender-role concept(appearance, activities, occupations, personality trails). Participants included 74 children(1st, 3rd, 5th graders). They were interviewed on a series of 16 pictures depicting cross-gender characteristics. Analyses revealed that (a) flexibility reached its peak at around age 8, which then remained the same except in appearance, (b) girls showed higher flexibility than boys except in occupations, (c) children showed the lowest flexibility in appearance and the highest in occupations, (d) children showed the lowest flexibility toward a male target child with cross-gender characteristic, and (e) children's justifications for flexibility were varied according to the situations. The results suggest that children's gender-role flexibility is influenced by age, sex, areas of gender-role concept, and target persons.

Background: Preoperative dexamethasone improves the surgical outcome after laparoscopic cholecystectomy(LC). The purpose of this study was to determine the effect of preoperative dexamethasone on the postoperativepain according to age and gender in patients who undergo LC.Methods: In this double blind prospective study, 400 patients, males or females :< 45 yr and males or femaless 65 yr (n = 50 in each of eight groups) who undergoing LC were randomized to receive dexamethasone 8mg (5 ml) or saline 5 ml intravenously 100 minutes before their operation, Postoperative pain was assessedon a visual analog scale (VAS) at 1, 6, 12, and 24 hour, and the time to administering the first postoperativeanalgesics was recorded.Results: Dexamethasone was administered without consideration for age and gender, and it reduced thepostoperative pain VAS score at 1, 6, and 12 hours, and the opioid analgesic requirement, but there was nosignificant difference between administering saline or dexamethasone in the same gender and age groups.Females U 45 yr who were administered saline had the most pain sensitivity and males S 65 yr who wereadministered dexamethasone had the least pain sensitivity.Conclusions: Preoperative dexamethasone reduces the pain intensity and opioid consumption, but does notreduce the pain intensity, according to age and gender in the patients undergoing LC. As a result, Preoperativedexamethasone should be considered for routine use for patients who are undergoing laparoscopic cho-lecystectomy. (Korean J Pain 2008; 21: 51 56)

This study was designed (1) to examine adolescents' body cathexis, ideal body image, clothing behavior, and clothing purchasing behavior, and (2) to identify gender and age differences. Descriptive statistics, Chi-Square ($\chi^2$) analysis, Analysis of Variance (ANOVA), and Duncan-Test were employed to analyze the data collected from the convenience sample of 729 middle- and high-school students in Gyeongnam, Korea. Adolescents tended to be dissatisfied with their body, while female high school students' dissatisfactory degrees were higher The ideal body image was thinner than normal, and neither gender nor age differences were observed. Adolescents showed higher dependences compared to other clothing behaviors including conformity, fashion, popularity, brand, and exhibition, and gender and age differences were observed. Fit/comfort and clothing displayed in store were most important evaluative criterion and information search method. Adolescents tended to prefer shopping in department store with friends or parents in less than 3 hours. Gender and age differences were observed in those clothing purchasing behavior. Marketing strategies generated from the results of this study were suggested.

Gender differences in the trace elements of monkey sino-atrial (SA) node were investigated in a process of age-dependent alterations. Sixty hearts from Japanese and rhesus monkeys (30 male and 30 female) used were aged ranging from 1-day- to 30-year-old. The elements were analyzed using an inductively coupled plasma-atomic emission spectrometer (ICP-AES). Advancing age decreased all the trace elements. Ca, P, S and Mg significantly decreased. The correlation coefficients of Ca and P were $-0.178{\pm}0.081$ (p<0.05) and $-0.088{\pm}0.022$ (p<0.05) in male (n=30), and $-0.095{\pm}0.026$ (p<0.05) and $-0.069{\pm}0.017$ (p<0.05) in female (n=30), respectively. The age-dependent coefficients for Fe/Ca, Zn/Ca, Fe/P, Fe/S, Zn/S, Fe/Mg and Zn/Mg were exhibited markedly in male, but all was less in female. In gender-related differences, only a ratio of P/Ca (p<0.05) was significantly observed with ageing. The trace elements such as Cu, Se and Sn were less detected in the SA nodes. These results indicate that the age-dependent changes in the ratios of elements are appeared more rapidly in male monkey SA node, and the gender difference is observed in ratio of P/Ca. The different attenuations may be involved with the age- and gender-related SA nodal functions.
