Objectives. Changes in lung function are frequently used as biological markers to assess the health effects of criteria air pollutants. We tried to formulate the prediction models of pulmonary functions based on height, weight, age and gender, especially for children aged 12 years who are commonly selected for the study of health effects of the air pollution. Methods. The target pulmonary function parameters were forced vital capacity(FVC) and forced expiratory volume in one second(FEV1). Two hundreds and fifity-eight male and 301 female 12-year old children were included in the analysis after excluding unsatisfactory tests to the criteria recommended by American Thoracic Sosiety and excluding more or less than 20% predicted value by previous prediction equations. The weight prediction equation using height as a independent variable was calculated, and then the difference of observed weight and predicted weight (i.e. residual) was used as the independent variable of pulmonary function prediction equations with height. Results. The prediction equations of FVC and FEV1 for male are FVC(ml) = $50.84{\times}height(cm)+7.06{\times}weight$ residual 4838.86, FEV1(ml) = $43.57{\times}height(cm)+3.16{\times}weight$ residual - 4156.66, respectively. The prediction equations of FVC and FEV1 for female are FVC(ml) = $42.57{\times}height(cm)+12.50{\times}weight$ residual - 3862.39, FEV1(ml) = $36.29{\times}height(cm)+7.74{\times}weight$ residual - 3200.94, respectively.

In Pingyu, China, 2003, murders caused by the game occurred. The perpetrator murdered 17 people under 20 years old by imitating the character of warrior of the game in the real world. This event was to draw the public's attention to a change of mentality and morality of the youth from the game. People have pointed to the problem of emotional design in the process of designing online games. Game designers have not considered making the game in the most ethical component. The moral element of the game design is a very important factor in forming the psychological changes and outlook on life and values of gamers. Therefore, to understand the rational moral standards is an important part of the online game design. This paper aims the design of a "moral system" role, contents and tasks settings and community game design elements of the game by using a systematic process of the moral element in online gaming. Hence the result is the formation of moral attitudes and values to the user of the online game allows the gamers to introduce a moral system in online games.

Objectives: This study investigates the current state of consuming breakfast among elementary school students residing in Malang, East Java, Indonesia, and to identify factors that influence breakfast behavior. Methods: The research model was set up as per the health belief model, and slightly modified by adding the subjective normative factors of the theory of planned behavior. The survey was conducted from July 17 to August 15, 2017 using a questionnaire, after receiving the permission PNU IRB (2017_60_HR). Results: The subjects were 77 boys (49.4%) and 79 girls (50.6%) suffering from malnutrition with anemia (21.2%) and stunting ratio of Height for Age Z Score (HAZ) (11.5%). Furthermore, moderate weakness (14.8%) and overweight and obesity (12.3%) by Body Mass Index for Age Z Score (BMIZ) were coexistent. According to the results obtained for breakfast, 21.8% did not eat breakfast before school, with 18.8% of the reasons for skipping breakfast being attributed to lack of food. Even for subjects partaking breakfast, only about 10% had a good balanced diet. The average score of behavioral intention on eating breakfast was 2.60 ± 0.58. The perceived sensitivity, perceived severity, perceived benefits, and self-efficacy of the health belief model correlated with breakfast behavior. Of these, self-efficacy (β=0.447, R²=0.200) and perceived sensitivity (β=0.373, R²=0.139) had the greatest effect on breakfast behavior. Mother was the largest impact person among children. Conclusions: In order to increase the level of breakfast behavior intention among children surveyed in Indonesia, we determined the effectiveness by focus on education which helps the children recognize to be more likely to get sick when they don't have breakfast, and increase their confidence in ability to have breakfast on their own. We believe there is a necessity to seek ways to provide indirect intervention through mothers, as well as impart direct nutrition education to children.

Analysis on Kandinsky's Work as a Case Study of Art Therapy. This study attempts to analyze a work of W. Kandinsky, who placed great emphasis on the relationship between the form and the color of an object, from the viewpoint of art therapy. Most papers related with fine art work analysis approach it from the aesthetical point of view and there are few attempts to interpret art works in terms of art therapy. This study tries to present a new angle to the studies of art therapy Practiced up to now and research is made on its potentiality. With an analysis on the relationship between human psychology, and color and form that convey visual language, research is made on the feasibility of art therapeutic methods through the approaches based on color psychology, Gestalt theory and perception psychology. The final purpose of this study is to apply the results to the development of illustrations, education program for children, and educational instruments and toys that will promote children's healthy emotional growth based on the color psychology and the form psychology of human being. As an initial study, a piece of Kandinsky's work, titled ' CERCLES DANS CERCLE', is analyzed as a case study of art therapy both from theoretical standpoint and from the viewpoint of art therapy. Through this effort, it can be utilized as a new case study of art therapy that will influence human emotion positively and lead to healthful emotional catharsis.

The purpose of this study was to examine the effect of eating with family or alone on the self-rated mental or physical health and then work out strategies of making people recognize the importance of eating with family and its practice. Study subjects were 610 primary school 5th- and 6th-grade students in Daejeon Area. A questionnaire survey was carried out. 57.9% of students had working mothers. The frequency of meal in a day was $2.90{\pm}0.42$ and this frequency was lower in students who had working mothers (p < 0.05). The frequency of skipping breakfast (times/week) was $1.02{\pm}1.77$. The frequencies of eating alone (times/week) were $1.04{\pm}1.65$ for breakfast and $0.97{\pm}1.52$ for dinner. Also, the frequency of eating alone for dinner was higher in students who had working mothers (p < 0.001). When the frequency of eating alone for breakfast or dinner was higher, the frequencies of skipping breakfast and dinner were also higher (for all, p <0.01). When the frequency of eating alone for breakfast or dinner was higher, the self-rated positive mental health were lower (p < 0.05 and p < 0.01 respectively) and the self-rated negative mental health (for dinner, p < 0.05) and the self-rated negative physical health was higher (p < 0.05 and p < 0.01 respectively), thus presenting negative health. The frequencies of eating with family (times/week) were $3.37{\pm}2.50$ for breakfast and $4.14{\pm}2.19$ for dinner. Also, the frequency of eating with family for dinner was lower in students who had working mothers (p < 0.01). When the frequency of eating with family for breakfast was higher, the frequency of skipping breakfast was lower (p < 0.01). When the frequency of eating with family for dinner was higher, the frequency of skipping dinner was lower (p <0.01). In addition, when the frequency of eating with family for breakfast or dinner was higher, the self-rated positive mental health were higher (for both, p <0.01) and the self-rated negative mental health was lower (for breakfast, p < 0.01) and self-rated negative physical health were lower (for both, p <0.01), thus presenting positive health. Therefore, in order to maintain positive health, it is necessary to recognize the importance of eating with family at home and educate people to carry out a systematic and continuous dietary life, thus increasing eating with family and reducing eating alone and skipping a meal.

This paper illustrates the inter-relationship between the theta/alpha ratio of the EEG signal and multiple HRV related parameters associated with the cardiovascular system response during event-related stimuli. Both EEG and PPG signals were simultaneously recorded in 21 healthy subjects. All subjects had their attention focused on the CNT program for nine minutes. Time-frequency analysis was applied to the EEG and PPG signals. The theta/alpha ratio was extracted from the EEG results, and the HRV features, including beat interval(1), SDNN(2), RMSSD(3), NN50(4), LF(5), HF(6), and LFIHF(7), were extracted from the PPG. Through multiple linear regression, the relationship ($R^2$) between the multiple combined features and the theta/alpha rhythm was identified. As a result, the combinations of $R^2$($R^2=0.253$; seven dimensions) and the theta/alpha ratio indicated a higher inter-relationship value than those of other combinations. The combinations of features that were greater than three dimensions, based on {SDNN(2), HF(6)}, generally showed higher $R^2$ value. We demonstrate that the high dimensional combinations had a higher correlation than did the low dimensional combinations.

This study examined the oral health knowledge of childcare teachers and their awareness of the prevention effects against dental caries. The subjects in this study were 433 childcare teachers in Seoul, Gyeonggi Province, Busan and South Gyeongsang Province, on whom a survey was conducted for five months, beginning in March, 2013. Hospitals (56.6%) were the most common route by which the childcare teachers acquired oral health knowledge. Regarding the distribution of the correct answers on oral health knowledge, every teacher gave the correct answer to the item "When a tooth comes out, it should be kept in milk and then be brought to a dental clinic," and the smallest number of them (35.1%) gave the correct answer to the item "When a tooth comes out, it should be washed with water." Concerning the level of oral health knowledge, the respondents, who worked in Busan and South Gyeongsang Province (p<0.001), who worked in childcare centers with more children (p<0.001), who were younger (p<0.001), and who were junior college graduates (p=0.002) had better oral health knowledge. In regard to the awareness of the prevention effects against dental caries, the respondents who were older (p<0.001) and who were married (p=0.002) were more aware of the prevention effects. According to position and career, teachers who were assistant principals (p=0.023) and had worked for 10 years or more (p=0.009) were more aware of the effects. Therefore, child care teachers should acquire accurate knowledge to improve the oral health of children, and regular training programs for age and education are needed.

Purpose: Maternal-fetal attachment in a pregnant woman is important for her health and for her child's emotional stability. This study was done to identify the contribution of maternal fatigue, social support, and Taegyo to maternal-fetal attachment based on a survey of pregnant women. Methods: The study was a descriptive correlation study. Participants were 211 from two women's health clinic centers. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. Results: Mean scores for maternal-fetal attachment, Taegyo, maternal fatigue, and social support were 93.74 (range 25-125), 64.76 (17-85), 24.12 (10-40), and 54.43 (22-132), respectively. There were significant differences in maternal-fetal attachment according to parity, breast feeding experience, and putting prenatal education into practice. Multiple regression analysis showed that the key determinants of maternal-fetal attachment, were Taegyo (${\beta}$=.67), maternal fatigue (${\beta}$=.21), and social support (${\beta}$=.13), and these explained 55% of the total variance of attachment. Conclusion: The results suggest a need to encourage Taegyo in prenatal management program and provide methods for fatigue resolution and promotion of social support.

This study aimed to evaluate the relationship between parenting styles and childhood dental caries using a sample of 3 to 6 years old children in Korea. The subjects were 158 children aged 3 to 6 years old and their parents in Korea. The parenting styles were divided into three groups (authoritative, authoritarian, and permissive) using a translated version of the Parenting Styles and Dimensions Questionnaire (PSDQ). Among the 353 parents/child dyads, 158 questionnaires were returned. Authoritative parenting style was the majority (95.6%), followed by authoritarian (3.8%), and permissive (0.6%). There were no statistically significant differences between dental caries and parenting styles. The mean of dft index in authoritative group was lower than others. In the authoritative domain, the higher the authoritative tendency, the lower the dft index. Overall, authoritative parenting styles resulted in low rates of dental caries for the children. The stronger the authoritative tendency of the parents, the lower the experience of dental caries in the children. Therefore, parenting styles were likely to affect the oral health of a child, but it seemed necessary to supplement the evaluation tool to evaluate the parenting styles.
