Body fat proportion is a major issue in health. The prevalence of obesity in childhood has been increasing on thesedays. A series of indirect estimates of body fat have been developed. There are hydrodensitometry, BIA and anthropometry equation for body fat. Hydrodensitometry has been regarded as a common criterion method. BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. The purpose of this unvestigation were to compare body fat and other body composition between boys & girls and to know which anthropometry equation for body fat was most closely associated with BIA in boys & girls respectively. The subjects were 148 4th grade elementary school students(male:70, female:78). They underwent BIA(InBody 3.0, Biospace Korea)to determine body fat and other body composition. Anthropometric measurements were taken of height, weight, skinfolds and circumferences. The results obtained are summarized as follow: 1) Weight, BMI and Rohrer index were $39.9{\pm}7.2kg$, $20.5{\pm}8.0$, $138.2{\pm}17.0$ for boys and $35.9{\pm}6.7kg$, $18.2{\pm}2.6$, $96.6{\pm}13.6$ for girls. 2) Total body fat and percent body fat determined by BIA were $10.3{\pm}4.3kg$, $25.4{\pm}6.6%$ for the boys group and $9.3{\pm}3.8kg$, $25.1{\pm}6.0%$ for girls. 3) Mean triceps skinfold thickness was $20.5{\pm}6.1mm$ in boys, $17.0{\pm}5.1mm$ in girls and mean WHR was $0.88{\pm}0.4$ in bodys, $0.82{\pm}0.4$ in female and the values were significantly different by sex. 4) Correlational nanlyses showed that estimation of body fat by BIA measurement seemed to be closely associated with Rohere index(boys r=0.854, girls r=0.909). Kim's equation was highly correlated with the body fat in girls(r=0.910) but less correlated in boys(r=0.710). We need to develop specific anthropometric equations based on age and sex to determine body fat for children.

목적: 양성 골종양 제거후 발생한 골결손을 골 대체물의 하나인 calcium sulfate를 이용하여 치료하고 그 결과를 보고하고자 한다. 대상 및 방법: 2000년 12월부터 2001년 11월까지 18명, 18례의 양성 골종양 환자에 대하여 calcuim sulfate(Osteoset$^{(R)}$:Wright Medical Co. USA)를 골 대체물로 이용하여 치료하였다. 남자 11명, 여자 7명이었으며 평균 연령은 28.4세였다. 모든 예에 대해 골결손 부위를 steoset$^{(R)}$을 이용하여 치료하였고, 자가골과 함께 사용한 경우가 6례, 동종골과 함께 사용한 경우가 2례, Osteoset$^{(R)}$ 단독으로 사용한 경우가 10례이었다. 추시기간은 최단 8개월에서 최장 19개월로 평균 12.3개월이었다. 주기적인 추시에서 관찰된 단순 방사선 사진에서 Osteoset$^{(R)}$의 흡수 정도와 골 생성 정도를 술 후 사진과 비교하여 백분율로 표시하여 관찰하였다. 결과: 술 후 3개월에 92 %의 흡수율을 관찰할 수 있었고, 술 후 6개월에는 89%의 골 생성을 관찰할 수 있었다. Osteoset 단독으로 사용한 경우나 자가골 또는 이종골을 같이 사용한 경우에서 흡수율이나 골 생성에 유의한 차이는 없었으며, 술 전 진단이나 병변 부위에 따른 차이도 발견할 수 없었다. 최종 추시시 특이한 합병증은 없었다. 결론: Calcium sulfate는 생체 적합성이 뛰어나고, 큰 골결손 부위에도 사용할 수 있으며 쉽게 사용 가능하고 골전도 작용이 있는 등의 장점을 가지고 있다. 따라서 양성 종양의 제거시 발생한 골결손의 치료제로, 특히 자가골 이식이 어려운 소아에서 유용하게 사용할 수 있을 것으로 사료된다.

Background: Breast cancer (BC) is the most common form of cancer in Iranian women, and it remains a major health problem. An increasing number of young women are being diagnosed with BC, and therefore, there is an increasing likelihood that more women will survive breast cancer for many years. Many opine that self-disclosure of BC diagnosis is important because talking about cancer helps people to make sense of their experiences; in fact, self-disclosure appears to play an important role in many health outcomes. However, this has not yet been studied in BC patients in Iran. Therefore, this study aimed to explore the status of self-disclosure of BC diagnosis by Iranian women to friends and colleagues. Materials and Methods: All BC records for 2001-2011 of employed women were studied at five hospitals in Mashhad. Data about the self-disclosure of BC diagnosis were gathered through telephone interviews, and the participants filled out a questionnaire about their status of self-disclosure of BC diagnosis to various groups of people. Results: The mean age of employed women at the time of diagnosis was $44.3{\pm}6.7$ years. Over 60% self-disclosed to work colleagues and over 90% to bosses/managers. Seventy per cent reported that they had support from their family and husband's family, while 95% reported that they had support from parents, siblings, children and friends. Conclusions: Most employed women self-disclosed freely to family, friends, colleagues and bosses/managers. Apparently, self-disclosure of breast cancer diagnosis may have negative effects at work. About half of patients reported that they had support from family, managers and colleagues; however, for nearly 28% of employed women, disclosure had less positive effects. In particular, it altered their perception of others, produced difficulties with work and family and diminished closeness with the people who were told. However, the stigma of BC is far less than it once was.

BACKGROUND/OBJECTIVES: Although the association of body mass index (BMI) with metabolic syndrome (MetS) is well documented, there is little knowledge on the independent and joint associations of BMI and physical activity with MetS risk based on a continuous scoring system. This study was designed to explore the effect of physical activity on interactions between excess body weight and continuous metabolic syndrome (cMetS) in a nationwide survey of Iranian children and adolescents. SUBJECTS/METHODS: Data on 5,625 school students between 10 and 18 years of age were analyzed. BMI percentiles, screen time activity (STA), leisure time physical activity (LTPA) levels, and components of cMetS risk score were extracted. Standardized residuals (z-scores) were calculated for MetS components. Linear regression models were used to study the interactions between different combinations of cMetS, LTPA, and BMI percentiles. RESULTS: Overall, 984 (17.5%) subjects were underweight, whereas 501 (8.9%) and 451 (8%) participants were overweight and obese, respectively. All standardized values for cMetS components, except fasting blood glucose level, were directly correlated with BMI percentiles in all models (P-trend < 0.001); these associations were independent of STA and LTPA levels. Linear associations were also observed among LTPA and standardized residuals for blood pressure, high-density lipoprotein, and waist circumference (P-trend < 0.01). CONCLUSIONS: Our findings suggest that BMI percentiles are associated with cMetS risk score independent of LTPA and STA levels.

Medical diagnostic X-ray workers are one occupational group that expose to the long-term low-dose external radiation over their working lifetime, and they may under risk of different cancers. This study aims to determine the relationship between the occupational X-ray radiation exposure and cancer risk among these workers in Jiangsu, China. We conducted Nested case-control study to investigate the occupational X-ray radiation exposure and cancer risk. Data were collected through self-administered questionnaire, which includes but not limits to demographic data, personal behaviors and family history of cancer. Retrospective dose reconstruction was conducted to estimate the cumulative doses of the x-ray workers. Inferential statistics, t-test and 2 tests were used to compare the differences between each group. We used the logistic regression model to calculate the odds ratio (OR) and 95% confidence interval (CI) of cancer by adjusting the age, gender. All 34 breast cancer cases and 45 esophageal cancer cases that detected in a cohort conducted among health workers between 1950~2011 were included in this presented study, and 158 cancer-free controls were selected by frequency-matched (1:2). Our study found that the occupational radiation exposure was associated with a significantly increased cancer risk compared with the control, especially in breast cancer and esophageal cancer (adjusted OR=2.90, 95% CI: 1.19-7.04 for breast cancer; OR=4.19, 95% CI: 1.87-9.38 for esophageal cancer, and OR=3.43, 95% CI: 1.92-6.12 for total cancer, respectively). The occupational X-ray radiation exposure was associated with increasing cancer risk, which indicates that proper intervention and prevention strategies may be needed in order to bring down the occupational cancer risk.

The purpose of this study were to develop a smoking preventive education program for elementary students and evaluate it's effectiveness. This study was a quasi experimental study under the nonequivalent control group with pretest-posttest design. The subjects of this study were 62 who are attending elementary school(31 for each group), 2 different district elementary school. The subjects were matched by grade, similar in anti-smoking educational background of smoking, as well as their residence and income level of their families. The instruments used in this study was 18 criterion referenced test items modeled by Dick & Carey that were developed by researchers for evaluating the subjects' knowledge and attitude about smoking. A pretest was administered a week before treatment The program given to the experimental group is composed of the texts explaining the poisonous substances in tobacco, social and cultural harmfulness of smoking to the body and psychology, indirect smoking, smoking of pregnant women, motives of smoking, refusal skills of smoking; and for the subjects' understanding and the better results of study - pictures, role play, discussion, text through computer based multi-media, puzzle searching for hidden pictures, cross-word puzzle, and finally compensation. The data were collected for 50 days form mid- September to the end of October in the year of 2000, composed of formative evaluation, pre-test and summative evaluation via 2 sessions. Accordingly, the collected data were analysed by t-test, paired t-test, repeated measure ANOVA by the SAS program. This research summarize the findings as follows; 1. There was a significant difference in knowledge between the experimental group(after 1 wks t=10.4680, p=.0001; after 4 wks t= 9.310, p=.0001) and control group(after 1 wks t=0.0420, p= .9669; after 4 wks t= -0.378 p=.7079) in between the results of 1 and 4 week after education in summative evaluation (F=27.45, P=.0001). 2. There was non statistical significant difference in attitude between the experimental group (after 1 wks t=1.2292, p=0.2286 ; after 4 wks t=1.330, p=0.1935) and control group (after 1 wks t=0.1819, p=0.8569 ; after 4 wks t=0.2970, p=0.7685) in between the results of 1 and 4 week after education in summative evaluation(F=0.71, P=0.494). To sum up, the statistics of conclusive analysis evaluative for the children under school age of the 'knowledge acquisition' about smoking harmfulness. On the other hand, as there was already sound attitude about smoking, the evaluation of attitude was non significant difference between control group and experimental group, just there was partially significant difference.

Objectives: The purpose of this study is to examine the different preferences between herbal medicine and health functional food, and analyze the reasons for the preferences to figure out the better way of promoting herbal medicine. Methods: 500 questionnaires has been handed out to the parents having elementary school students in Gyeonggi-do province, and 331 questionnaires has been collected and evaluated for this study. Results: Among the 331 responses, 58.4% were female, and 41.6% were male. The percentages of the subjects who consume health supplements and that of herbal medicines were 67.4% and 59.2% respectively. The preference rate for the health supplements was 57.6%, and for herbal medicines was 42.4%. The major reason of taking the health supplements was that they were convenient to consume(54%). The major reason for choosing herbal medicines was that people 'expect them to be more effective'(72.7%). However, the problem with Herbal medicine was their consumptions were inconvenient (39.8%), and their tastes was unfavorable. The most preferable form of herbal medication was pills(50.6%), followed by syrup(22.9%). Pertinent price for herbal medication, the participants were favorable to pay 30,000 within a week. For the question on when to start taking the herbal medication, 18 months after was the popular answers from the participants. Conclusions: Among the 331 subjects, the percentage of consuming the health supplements (67.4%) was higher than that of consuming the Herbal Medicine (59.2%). Also the preference was higher than the Herbal Medicine. The reason why the participant preferred health supplements was that they were 'easy to take', The reason for subjects' great preference in herbal medicine was based on their conception that herbal medicines were highly effective. When taking herbal medicine, participants addressed inconvenience in consuming, and unfavorable taste as the biggest problems. Also they thought that pills would be most convenient form of herbal medicine to consume. For the proper price, they were willing to pay less than 30000won, lower than a market price, per a week for the herbal medicine. Most parents thought that proper age of taking herbal medicine is ' 18 month after the birth'. Taking these into account, different perspectives on herbal medicine is necessary at the very moment.

1. Introduction Community medicine with the concept of comprehensive medical care and an ideal medical care delivery system not only for an individual or family but for the whole community has emerged. In April 1970, the Presbyterian Medical Center started a hospital based community health service project in order to improve the health of the people in rural areas. Prior to commencing a comprehensive medical care system, a family survey was needed. The major objective of this survey was to obtain information concerning the people and their environment so as to be able to plan and implement a comprehensive medical care program in Soyang-Myun. 2. Survey Method An interview using a family record form was carried out for each household. This family record form was designed to get information about demography, family planning, environmental sanitation and vital statistics. Prior to beginning, the members of the survey team were trained in interviewing techniques for three days. The team consisted of a public health nurse, four nurse-aides, a sanitarian and four health extension workers who are working in our project, The survey was carried out during the period November 1971 to March 1972. 3.
