The purpose of this study was (1) to examine the impact of chronic diseases and emotional-behavioral problems on school-age children's self-perceived QOL, and (2) to investigate what factors were related to the QOL of children. Participants were 972 Korean 4th, 5th, & 6th grade students and 47 teachers. Children completed a questionnaire to evaluate their self-perceived well-being and subjective health. Also they reported their height/weight and physical health state indicating whether they have chronic diseases or not. Teachers reported each child's psychosocial health problems and also reported whether the child has chronic diseases or not. Major findings were as follows : 1. Physical and psychosocial health status had significant impact on school-age children's QOL. Moreover, physical and psychosocial health status were interrelated. 2. Presence of physical and psychosocial problems contributed to substantial declines in self-perceived QOL of school-age children. Children who have chronic diseases and emotional-behavioral problems reported significantly lower QOL compared with children in a normal state. 3. Peer relationship was found to be the significant factor that contribute to the QOL of all children.

The aim of this study was to determine the extent to which sociodemographic and health related life-style variables explain body weight distribution and to understand weight contol behavior. To study this study 298 students were selected, it was consisted of obesity group(101) and control group(197). The average age of subjects was 14.2 and the prevalence of obesity was 2-3 per class as 5.6% among 1,793. 71% among same subject was showed higher weight pattern than last one year, ovesity group which was obesity both in 93 and 94 was 34%. Correlation between body weight(under weight/obesity) and independent variables including sociodemographic factor and health- related life style tested through Multiple Classification Analysis was very significant, explained 36% of the total variance. Sociodemografic and hereditary factors such as education level, age of father and physical features of parents, life style factors as exercise preference and perceived health status showed highly contribution to body weight. Concretely, there were showed a higher obesity prevalence tendency when education level and age of father was high, physical features of parents was obesity. In otherwise, there were showed a higher underweight prevalence tendency when education level and age of father was low. Experience rates of weight control was 53% generally, 84% in obesity group, and 11% in underweight group. There were utilized weight control behaviors through diet method mainly in obesity group, diet and exercise methods in underweight group. There were showed that underweight group are prefer exercise to obesity group. Conclusionally, These findings suggest that education, age, physical features of parents, exercise preference and perceived health status is important factors related to body weight among middle school girls. Therefore, there will be considered as valuable factors when we practice health education and consultation related to body weight. Furthermore it is necessary to provide of various informations about weight control and to develop systematic weight control program.

Objective: This study aimed to evaluate the zygomaticotemporal suture (ZTS) maturation, analyze the age distribution patterns of ZTS maturation stages, and investigate the relationship between ZTS and cervical vertebral maturation (CVM). Methods: A total of 261 patients who underwent cone-beam computed tomography (112 males, mean age, 13.1 ± 3.3 years; 149 females, mean age, 13.7 ± 3.1 years) were examined to evaluate the ZTS stages. The ZTS stages were defined based on a modified method from previous studies on zygomaticomaxillary sutures. Differences between groups and correlations between indicators were analyzed using the Spearman correlation test, intraclass coefficient of correlation (ICC), one-way analysis of variance and rank sum test. Statistical significance was set at p < 0.05. The diagnostic value of CVM stages in identifying ZTS maturation stages was evaluated using positive likelihood ratios (LRs). Results: A positive relationship was found between the ZTS and CVM stage (r = 0.747, ICC = 0.621, p < 0.01) and between the ZTS stage and chronological age (r = 0.727, ICC = 0.330, p < 0.01). Positive LRs > 10 were found for several cervical stages (CSs), including CS1 and CS2 for the diagnosis of stage B, CS1 to CS3 for the diagnosis of stages B and C, and CS6 for the diagnosis of stages D and E. Conclusions: The ZTS maturation stage may be more relevant to the CVM stage than to the chronological age. The CVM stages can be good indicators for clinical decisions regarding maxillary protraction, except for CS4 and CS5.

Developmental changes of dental arch width and length from 6.6 to 13.6 yews of age have been studied in twenty boys and thirteen girls in Korean school children. A series of 8 dental casts obtained from each child was measured in the intercanine width, intermolar width and arch length. Afterwards, mean value and each standard deviation of each age group and each gender were obtained, and corresponding graphs were drawn. The finding of this study can be summarized as follows : 1. Maxillary intercanine widths increased until age of 13.5 in males and age of 12.5 in females. On the other hand, mandibular intercanine widths increased until age of 11.5 in males and age of 9.6 in females and after there were no changes. 2. Maxillary intermolar widths increased until age of 13.5, but annual increments reduce from age of 12.5 in both sex. Mandibular intermolar widths increased until age of 13.5 in males and age of 12.5 in females. Annual increments of maxillary intermolar width greater than those of mandibular intercanine width in both sex. 3. Maxillary dental arch lengths increased until age of 10.6 in both sex, and after decreased until age of 13.6. Mandibular dental arch lengths increased until age of 10.5 in males and age of 9.6 in females, and after decreased until a9e of 13.6. 4. Developmental changes of dental arch width and length showed individual variation.

To estimate the incidence rate of coronary heart disease in Korea, of all residents in Taegu city aged 25 or above, those who had an acute MI or a fatal coronary event between 1 July 1996 and 30 June 1997 were registered. Seven hundreds and eight patients were registered during the study period(685 were identified at hospital and 23 were autopsy cases). Age-standardized annual incidence rate of men in city area was 93 per 100,000(95% CI; 61-142) and 35% CI; 16-67) in women(100 in men and 20 in women aged 35-64). The incidence was rapidly increased after age 40 in men, however, in women after age 60. Twenty-eight-days case fatality rate was 45% in men and 47% in women. However, in the age group of 45-59 case fatality rate in women was two times higher than that in men. In conclusion, crude annual incidence rate of CHD in city area was 73 per 100,000 in men and 33 in women. The age-standardized annual incidence of CHD in men(93 per 100,000) was 2 times higher than that in women (33 per 100,000) in Korea.

Purpose: This paper aims to examine the subjective structures and types of school age children's perception of death through an investigative study on their perception of death in order to provide a basic material for them to understand death, and develop and carry out an effective death education program. Methods: The study method used the Q Methodology which can investigate the subjective structures and types of school age children's perception of death. For Q-population, 20 school age children were used as subjects for neutral interviews and open surveys, and through documentary research, a total of 132 statements were collected, For Q-samples, 23 statements (Q-samples) were derived through a non-structural method. P-samples were 31 school age children (8-13 year olds), Q-sorting was carried out using Q-cards, and the collected data was analyzed using the PC QUANL program. Results: As a result of the study, children's perception of death was divided into five types. The first type was functional type, characterized by prominent subjective perception regarding the elements of death, such as non-reversibility, universality, non-functionality, and causality. The second was after-life type, characterized by a strong, focus on life after death in one's perception of death, and it included children with Christian background and those who had experienced death in their immediate family. The third was religious type, characterized by a strong belief in being able to still watch over one's family and friends after one's death, resulting in a positive faith in the after-life. The fourth was fearful type, characterized by a deeper fear of death in comparison to other types. The fifth was realistic type, characterized by a strong and positive assent to the perception of good death. Conclusion: The significance of the results of this paper's study to Nursing is as follows. In terms of understanding the subjectivity of school age children's perception of death in nursing practice, and understanding the compositional elements of death presented with strong emphasis in existing literature and studies, the results will expand these understandings and allow us to understand the level of perception in school age children regarding the definition of death, after-life, and good death, be utilized as useful material in developing an effective death education program for them according to their type characteristics, and become the fertilizer for enabling the children to live a proper life and preventing the tendency to make light of death that occur in adolescence and the spread of suicides. In terms of nursing theory, the description and examination of the subjective structures and the characteristics of the different, types of school age children's perception of death can be utilized as useful material for building a model of school age children's perception of death, and be further used for teaching respect for life. In terms of nursing research, the results can contribute to research describing the effects of nursing intervention strategies and developing tools for providing psychosocial nursing in terms of giving school age children a positive perception of death according to their types as well respect for life.

This study aims at helping cerebrally palsied children to overcome and minimize their sufferings, inducing them to perform ordinary activities of daily living for themselves by coducting ADL Tests which are fundamental activities in daily life and presenting treatment plan for their overall rehabilitation and basic data for achieving the training objective. For that purpose, 173 cerebrally palsied children were selected and given ADL performance Tests from Dec. 1987 to Oct. 1988 and the following results were obtained. 1. Correlation coefficients for each ADL category indicated significant statistical value at .01 level. 2. Correlation coefficient between school-year variable and ADL category variable was significant at .01 level. 3. Correlation between age variable and ADL variable category proved significant at .01 level as well. 4. Correlation coefficients between each category in terms of functional state of extremities were significant at .01 level. 5. The difference in ADL achievements between each category by school year were as follows ; 1) In the category of meeting nature's tall, the age span of more than 4 school years showed statistical significance. 2) In the category of putting off and on clothing, the age span of 3 school years indicated statistical significance. 3) In taking meals statistical significance was found in the age span of 4 school years. 4) In finger movements the age span of more the 4 school years indicated statistical significance. 5) In walking activities statistical significance was noticed in the age span of 2 or 3 school years. Besides, in category by school year, and exceptional case was noticed that the 6th graders were lower than the 5th graders in self-reliance rate. 6. the difference in ADL achievements by type of palsy, children of triplegia were the lowest, while those of monoplegia were the highest. 7. The difference in ADL achievements by kind of palsy, patients of athetosis showed lower rate of self-reliance than those of spasticity, and particularly the latter showed a high rate of self-reliance in taking meals$(83.5\%)$. The former were relatively low in self-reliance and lowerst in meeting nature's call $(59.8\%)$.

Background: We investigated four factors, height, weight gain since age 20, physical activity, and alcohol drinking, for associations with risk of breast cancer (BC) according to menopausal status, using the latest data of the Japan Collaborative Cohort Study (JACC Study). Materials and Methods: We confined the analysis to 24 areas available of cancer incidence information, excluding women with a previous diagnosis of BC. Baseline data were collected from 38,610 (9,367 premenopausal, and 29,243 postmenopausal) women during 1988 and 1990. The study subjects were followed-up at the end of 2009, and 273 (84 premenopausal, and 189 postmenopausal) cases of BC were newly diagnosed in 501,907 person-years. The Cox model was used to estimate a hazards ratio (HR) and its 95% confidence interval (CI) of BC risk. Results: As a result of the multivariate analysis adjusting for age at baseline survey, age at menarche, number of live births, and, age at first delivery, weight gain since age 20 of 6.7 kg-9.9 kg, and ${\geq}10.0kg$ were significantly associated with increased risk for postmenopausal BC (HR=2.48, 95% CI 1.40-4.41, and, HR=2.94, 95% CI 1.84-4.70, respectively). Significantly increased trend of BC risk was also observed in weight gain since age 20 (p for trend, p<0.001). Amount of ethanol intake per day${\geq}15.0g$ was significantly associated with increased risk for postmenopausal BC in the multivariable-adjusted analysis (HR=2.74, 95% CI 1.32-5.70). Conclusions: Higher weight gain in adulthood and larger amounts of ethanol intake were significantly associated with increased risk of BC in Japanese postmenopausal women. None of the investigated factors were significantly associated with BC risk in Japanese premenopausal women.
