The purpose of this study was to explore the perceptions of preservice teachers toward children from single parent families. 218 preservice teachers (209 female and 9 male) who were enrolled in the department of early childhood education and child care & education were participated in this study. A questionnaire was developed based on the questionnaire developed by Song, Sung, & Han (2003). Data were analyzed by using SPSS 11.5. The results were followed. First, preservice teachers' personal experiences of single parent families did not influence their perception of children from single-parent family. Second, preservice teachers who strongly held the view of keeping traditional family structure showed negative expectations of children's school adjustment. Third, preservice teachers reported the importance to help the children adjustment at school as well as to deal with their personal and family problem. The results presented that there was an increasing need in teacher education, to develop curriculum for preservice teachers to have balanced views or reduce their biased perception against diverse family structure and children from single parent families.

Purpose : This study identified the patterns of smoking of students attending middle schools and high schools, and analyzed its related health risk behaviors. Methods: The data was based on the survey of 1,517 middle students and 911 high students residing in Kyung-Gi district. Results: The current smoking rates of male and female middle students are 5.3%, and 3.1% respectively. The rates of experiences in smoking are 21.4% and 16.0%(male/female). The current smoking rates of male and female high students are 17.9% and 8.5%, whereas the rates of experiences in smoking are 34.2% and 23.3% respectively. On the other hands, 14.1% of middle students and 12.0% of high students were exposed to smoking for at least 2 hours per day. The majority of middle and high school smokers started smoking when they were in middle or high school. And the most popular places to smoke were children's playgrounds, public open area., parks, and so on. Whether having a smoker as a friend or not and students' own perception towards smoking influenced the decisions to smoke for middle and high students. Both middle and high students, regardless of their gender, who have higher rates of drinking experiences and the hours of computer usage were found to have higher rates of smoking experiences. Meanwhile, the sleeping hours is in reverse proportion to the rate of smoking experiences. There was statistically significant difference in smoking experiences related to the degree of obesity only in the female high students: underweight and overweight students showed higher rates of smoking experiences than those falling in the normal weight range. Conclusion: For the effective prevention of adolescence smoking, it is necessary to adopt a comprehensive approach, which classifies the target population according to their age and sex and cover all health risk behaviors.

This study investigated intake patterns of health functional foods(HFF) in elementary school children and requirements of their parents in the Daejeon area using a questionnaire by 432 parents. Participating parents were composed of female, 83.6% and male, 16.4%. Most of the parents were in their 40's(53.0%) and 30's(45.8%). 47.9% of the children were male and 52.1% were female. The school year of the children was distributed evenly, ranging from the first year to the sixth year. The intake rate of HFF for parents appeared to be 65.3% and for children it appeared to be 63.2%. The primary reason of using HFF to their child was 'For health promotion'(54.4%); the largest reason of non-using HFF was 'Do not feel necessity because is healthy'(48.8%). In regards to purchase place, 'Drugstore' was most selected by 26.1%, while the largest amount of purchase motive was 'Decided by oneself for children's health'(37.7%). The average expense per month was, 'Less than 50 thousand portion'(20.3%). The intake period, 'less than 6 months' was won' for 54.9%. For intake items, 'Vitamin supplementation products' was the largest portion'(20.3%) was indicated. The intake period, less than 6 months' was the most selected by 51.3%. Most people(66.7%) selected '1 kind' of intake item. As for intake effect, 45.4% claimed 'A little help'. In regard to experiencing side effects, 'Is not' was 92.7%, however, diarrhea, nettle rash, nausea etc. were a little. The biggest problem of HFF was 'Falsehood/exaggerative advertisement' as identified by 53.1%. For improvement of the HFF system was, 'Verify by more strict formality' as selected by 55.8%. In regards to experience of nutrition education on HFF, 'Is not' was most selected by 51.0%. The most desirous form of nutrition education was, 'Simple paper material'(31.3%). The most desirous content of nutrition education was, 'nutritional management of classified by life cycle'(37.2%). Therefore, HFF must be used properly to promote the health and growth development of children by acquiring scientific and reasonable information about the ability and usage of the food.

This study is focused on the effects of one's blood type on emotional character of children, by comparing each individual's brain wave. Observed records are from those kids who volunteered for KRIJUS(Korea Research Institute of Jungshin Science)'s brain wave measurement from September 2005 to December 2007. The whole 3018 kids(4-7) group consists of 1322 female and 1696 male. Blood types are A>B>O>AB dominately ordered. The relations between depressive attitude and blood type of an infant couldn't be found among female. However, male type B had the most numbers of activeness character while type O shown largest rate of depressed condition. Also, the result amongst infant had shown male type B had the most active-positive rate while type AB took large for depressed-negative. The result had shown no relative connection for activity inclination. Third, among the kids type O had highest awareness rate while type A had lowest. This study revealed meaningful relation between blood types and emotional character among several categories, while suggesting follow-up researches figuring out more detailed explanations for its effect and genetic role.

This study was designed to measure taste sensitivity and the five basic senses by an educational classification instrument. The instrument was a rice kit that could use samples in a dry powder form or oil extract after long-term storage To test for taste, sucrose, salt, citric acid, and quinine sulfate were made at different concentrations and taste sensitivity was measured on a scale from level 1 to level 5. To obtain baseline data, an inspection tool for the five senses was used and randomly applied on 101 schoolchildren in the third and fourth grade in the city of Cheonan in Korea. The inspection tool was composed of 17 questions; 5 questions regarding visual characteristics and three questions each for characteristics regarding taste, hearing, smell, and touch. The average age of the schoolchildren was 9.5 years old and there were 49 third grade students (9 years of age), and 52 fourth grade students (ten years of age). There were slightly more male students than female students, 56 (55.4%) compared to 45 (44.6%), respectively. The average height of female students was higher than that of males, but the average BMI (body mass index) of the male students was slightly higher than that of female students (18.28 compared to 18.09, respectively). Female students were slightly more sensitive to salty tastes than male students (2.8 compared to 2.5, respectively). In the score distribution for each sense, touch sense was the highest at 7.59, sight sense was 7.49, hearing sense was 5.43, smell sense was 5.24, and taste sense was lowest at 3.69. Therefore, schoolchildren first tend to recognize and deem important the touch and sight of food before its taste.

Objective: To estimate the projected cancer risk attributable to diagnostic cone-beam computed tomography (CBCT) performed under different exposure settings for orthodontic purposes in children and adults. Methods: We collected a list of CBCT machines and their specifications from 38 orthodontists. Organ doses were estimated using median and maximum exposure settings of 105 kVp/156.8 mAs and 130 kVp/200 mAs, respectively. The projected cancer risk attributable to CBCT procedures performed 1-3 times within 2 years was calculated for children (aged 5 and 10 years) and adult (aged 20, 30, and 40 years) male and female patients. Results: For maximum exposure settings, the mean lifetime fractional ratio (LFR) was 14.28% for children and 0.91% for adults; this indicated that the risk to children was 16 times the risk to adults. For median exposure settings, the mean LFR was 5.25% and 0.58% for children and adults, respectively. The risk of cancer decreased with increasing age. For both median and maximum exposure settings, females showed a higher risk of cancer than did males in all age groups. Cancer risk increased with an increase in the frequency of CBCT procedures within a given period. Conclusions: The projected dental CBCT-associated cancer risk spans over a wide range depending on the machine parameters and image acquisition settings. Children and female patients are at a higher risk of developing cancer associated with diagnostic CBCT. Therefore, the use of diagnostic CBCT should be justified, and protective measures should be taken to minimize the harmful biological effects of radiation.

The structure changes of the vocal folds are related to the fundamental frequencies (F0). In other words, the increasing in vocal fold length and thickness makes the result of dropping in the F0 during the mutational period. The purpose of this study was to investigate F0 of normal children's voice in mutational period. 360 children (180 boys and 180 girls) were participated in this experiment. The age was ranged from 11 to 16 years. The subjects were asked to produce sustained comer vowels (/a/ /i/ /u/) five times each and the data were analyzed using the MDVP of CSL. The result shows that the F0 are considerably decreased with age and reach to adults' F0 by 16 years in most cases. In particular, the F0 of male subjects were rapidly decreased between the ages from 12 ($226.98\;{\pm}\;19\;Hz$) to 13 years ($169.3\;{\pm}\;25\;Hz$), while the F0 of female subjects were slowly changed from the later period of 12 to 16 years old. This result may be used by the meaning of guideline and lead the basic data to differentiate between normal voice and voice disorder.
