Completeness is an important indicator of data quality in cancer registry programs. This study aimed to estimate the completeness of registered cases in a population based cancer registry program implemented in five provinces of Iran. Capture-recapture methods were used to estimate the number of cases that may have been missed and to estimate rates of completeness for different categories of age, year, and sex. The data used for this study were obtained from three sources: 1) National Pathology Database; 2) National Hospital Discharge Database; and 3) National Death Registry Database. The three sources were linked and duplicates were identified based on first name, last name, father's names, and date of birth, ICD code, and case's residency address using Microsoft Excel. Removing duplicates, the three sources reported a total of 35,643 cases from March 2008 to March 2011. Running many different multivariate models of capture-recapture and controlling for source dependencies revealed an overall under-reporting of 49% in all five registries combined. The estimated completeness differed based on age, sex, and year. The overall completeness was higher for males than females (71.2% for males and 59.9% for females). Younger age had lower rates of completeness compared to older age (38.1% for <40 years, 55.4% for 40-60 years, and 76.7 for >60 years). The results of this study indicated a moderate to severe (depending on the age, sex and year) degree of completeness in the population based cancer registration of Iran.

The purpose of this study is to investigate the need of home economics education on high School male students for purpose, the questions raised in this study are as follows. 1. Does home economics education on high school male students needs\ulcorner and are whether not or home economics education on high school male students need different according to sex, age, edu-cation, income, occupation\ulcorner 2. If home economics education on high school male students need or not. What is the reason of that\ulcorner and are the reason of that different according to sex, age, education, income, occupation\ulcorner 3. If home economics education on high school male students need, what is the contents of home economics education and are that different according to sex, age, education, income, occupation\ulcorner The subjects of the study consisted of 183 men and women in Ch’ong ju City(over 21 years old) The data were analiged by statistical procedures such as frequency, X(sup)2, oneway ANOVA, two-way ANOVA, Duncan’s Multiple Range Test. The major results of the study were summarized as follow: 1. The response rate on home economics education on high school male students was absolutely high(91.8%). of demographic variables, the only sex appeared the significant differences. the men groups responsed higher not to need than the women groups. 2. As the reasons of home economics educations on high School male students needing the respons of the highest response rate were that ‘as family community, family members understant, cooperated, and are responsible with each other or one anther’and that ‘as society becomes in-dustrial gradually, family members have to have the accurate perception, or attitudies on home life’of demographic variables, sex, income, and occupation appeard the significant differences. In the contrast of that, as the reaspon of home economics education on high school male stu-dents not needing, the reasons of the highest. response rate were that ‘as sex, the role is different’and that ‘home economics education needs not essentially to learn through the school education’. and there were not differences according to demographic variables. 3. As home economics education contents for high school mal students, the most need content part was child part. the second content part was family development and family relationships part. There was the significant differences according to all the demographic variables. Particulary, the lower the lever of education, in come and occupation were, the less the degree of need on all content part was.

The objective of this study was to investigate the effects of hatch and sex on the body weight and shank length of growing pheasant. Least squares means of body weight at the age of 0, 4, 8, 12, 16 and 20 wks were 17.9, 96.0, 296.4, 563.4, 709.0 and 757.4 g for female, and 18.3, 104.4, 349.1, 728.5, 1001.4 and 1101.6 g for male, respectively. The hatch effect on body weight was significant at the age of 4, 8, 12 and 16 wks (P＜0.05), but the effects on shank length were significant at the age of birth and 8 wks only. There was no significant hatch effect on both the body weight and shank length at the age of 20 wks(P＞0.05). Least squares mean differences between female and male were significant(P＜0.01) over all wks of age except at hatch.

This study was designed to test the differences in children's social information-processing patterns and bahavioral characteristics among four different groups of peer status, and to evaluate the predictability of peer status from social information-processing and social behavior. In addition, age and sex differences were assessed. The subjects were 80 boys and 80 girls identified as popular, average, neglected, and rejected by their peers in the first and the third grade. They responded to a sociometric test and three hypothetical social dilemmas, while behavioral characteristics were rated by their teachers. The data were analyzed by ANOVAs, and discriminant analyses. The results showed that children's social information-processing patterns were not significantly different by peer status except the number of interventions requested. Whereas children's behavioral characteristics were different by peer status in all of the four domains. Children's social information-processing patterns and behavioral characteristics were different in part by age and sex. The important predictors of peer status were hyperactive-distractive, anxious-withdrawn, sociable-prosocial behaviors, and the number of interventions requested.

The aim of this study was to provide the basic 2-dimensional statistics requisite in the siting system and design of gloves. The 64 static measurements were selected to provide information about hands. Participants in the study were 824 adults, aged between 18 and 64. Subjects were divided into four age groups: 18 to 29, 30 to 39, 40 to 49, and 50 to 64, and separated according to sex. Statistical tests such as Descriptive Analysis, and Anova were conducted to analyze the data and ascertain the differences among the ages. The disparities between sex groups were compared by T-test. In addition, correlation among the 57 measurements was analyzed and the results were compared to the data from Japanese and other studies. The results indicated that all the measurements were significantly larger in the male group. There were significant differences among age groups for most hand circumferences, breadths and thickness items. As the age increased, the hand circumferences, breadths and thickness items became wider and thicker. In addition, as the age increased, the mean measurement value of the length items decreased, so that it became shorter. Hand length was highly correlated with finger length, palm length and height. Maximum hand circumference II was highly correlated with hand circumferences, hand breadth and weight.

This study explored proverb comprehension and use in elementary school children by familarity and concreteness of proverbs and children's age, sex, experience of living with grandparents. The 529 fourth and sixth grade participants completed a questionnaire probing knowledge of 16 proverbs; 4 each in four categories(familiar-concrete, familiar-abstract, unfamiliar-concrete, and unfamiliar-abstract). Results showed highest comprehension scores for familiar-concrete proverbs. Sixth graders obtained higher comprehension score than fourth graders in all four proverb categories. There was no difference between grades in frequency of proverb usage. An interaction effect between grade and sex showed that female sixth graders had the highest comprehension score. These results suggest a possibility of relationship between figurative language and cognitive development related to abstract thinking in late school-age children.

Objective: To investigate sex-specific correlations between the dimensions of permanent canines and the anterior Bolton ratio and to construct a statistical model capable of identifying the sex of an unknown subject. Methods: Odontometric data were collected from 121 plaster study models derived from Caucasian orthodontic patients aged 12-17 years at the pretreatment stage by measuring the dimensions of the permanent canines and Bolton's anterior ratio. Sixteen variables were collected for each subject: 12 dimensions of the permanent canines, sex, age, anterior Bolton ratio, and Angle's classification. Data were analyzed using inferential statistics, principal component analysis, and artificial neural network modeling. Results: Sex-specific differences were identified in all odontometric variables, and an artificial neural network model was prepared that used odontometric variables for predicting the sex of the participants with an accuracy of > 80%. This model can be applied for forensic purposes, and its accuracy can be further improved by adding data collected from new subjects or adding new variables for existing subjects. The improvement in the accuracy of the model was demonstrated by an increase in the percentage of accurate predictions from 72.0-78.1% to 77.8-85.7% after the anterior Bolton ratio and age were added. Conclusions: The described artificial neural network model combines forensic dentistry and orthodontics to improve subject recognition by expanding the initial space of odontometric variables and adding orthodontic parameters.

This study aimed to measure the impact of societal participation of Saudi banks on customer satisfaction and determine the statistical differences in customer satisfaction according to sex, age, income, education, and work type. Societal participation has economic and environmental dimensions. The study population includes all Saudis in the government, military, and private sectors reaching 3.58 million in 2021. The unit of analysis is Saudi customers of commercial banks. The 12 banks have societal programs. The research tool is a "Questionnaire," It is distributed face-to-face at places of work. The study concludes that economic participation has no impact on customer satisfaction; however, the impact of environmental participation on customer satisfaction is proved. The study shows no statistical differences in customer satisfaction according to mediators (sex, age, income, education, and work type). Despite the environmental participation being the tangible product by Saudi banks in the local market, the study concludes the positive relationship between societal participation and customer satisfaction. The study presents a set of recommendations for enhancing societal participation in the Saudi businesses environment.

The effect of sex ratio on behavior and welfare indexes in broiler chickens was investigated. Five variants of the sex ratio (male to female), namely, 100:0 (T1), 75:25 (T2), 50:50 (T3), 25:75 (T4) and 0:100 (T5) were tested in broilers between the ages of 7 to 35 days. It was found that the most common behavior in all sex ratios was resting behavior, ranging over 74.4 % of total behavioral frequency. The ranges of other behavior traits of total behavior traits were as follows: pecking, 5.4 to 23.1 %; standing, 1.8 to 24.8 %, and moving, 0.6 to 11.5 %. The behavioral frequency of resting, pecking, standing and moving were not affected by the sex ratio and between male and female. But the percentage of pecking, resting and moving behavioral frequency was significantly different by the age of birds (P<0.05). Age of birds had no effect on standing behavioral frequency. It seems that gait, food pad and hock burn score were no affect by sex ratio but tend to decreased in female than male. Claw length of 21 and 35 days was not affected by sex ratio and between male and female. The duration of tonic immobility (TI- reaction) was tend to decreased age of 21 than 35 days, and female than male. Both male and female of the study, hock burn score, claw length and TI-reaction were tend to lower in T4 than other treatments. The results suggest that, when male and female broilers are reared together, sex ratio can influence broiler welfare indexes in this study.

A statistical analysis on the cardiothoracic ratio in insurance medicine was carried out for 5,200 insured persons who were medically examined including photofluorography of the chest at the Honam medical department, Dong Bang life insurance Company, Ltd from November, 1979 to August, 1984. The results were as follows: 1. The mean value of the cardiothoracic ratio in all of the insured was $44.2{\pm}4.3%$. The mean value of the cardiothoracic ratio was $43.1{\pm}4.1%$ in all males and $45.2{\pm}4.2%$ in all females, and the difference of the values between males and females showed statistical significance(P<0.001). In each age group, the mean value of the cardiothoracic ratios of female was higher than that of male without exception and the difference of the values between males and females showed statistical significance(P<0.001). The mean value of the cardiothoracic ratio showed gradual increase with age from the second to sixth decade in male(P<0.05 or 0.001 after fourth decade) and from the second to seventh decade in female(P<0.05 or 0.001 from the second to sixth decade). 2. Correlation between both sexes and among age groups relating to the cardiothoracic ratios of the insureds seen to be a physiological phenomenon of the cardiac size and should be considered on the rating of the cardiothoracic ratio. Based on the correlation above mentioned and an author's assumption that the incidence of normal and abnormal cardiothoracic ratios in each age group would show the same rate in male and female, author prepared a modified rating table from the existing table; in male group the existing rating table is used and in female group the ratings of 0, 30-50, 50-100 and 100-D are to calculate by the cardiothoracic ratio of 51%or under, 52-56%, 57-61% and 62% or over respectively in the age group below 39, by the cardiothoracic ratio of 52% or under, 53-57%, 58%-62% and 63% or over respectively in the age group of 40-49, by the cardiothoracic ratio of 53% or under, 54-58%, 59-63% and 64% or over respectively in the age group over 60. 3. The relative frequency distribution polygons of the cardiothoracic ratio of both sexes drawn in a pair on one coordinate plane revealed lying in juxtaposition each other horizontally and showed the shifting of females polygon to male's one toward the direction of greater value of the cardiothoracic ratio at a short distance which increased gradually with age. 4. The minimum cardiothoracic ratio was 31.2% and the maximum cardiothoracic ratio was 63.6% in all of the insured. 5. In each age group, no significant sex difference was found in the relative frequency distribution of ratings by the cardiothoracic ratios of 5,200 insureds by using the rating table modified by author, while significant sex difference was found by using the existing rating table.
