Purpose: The purpose of this study was to describe breastfeeding knowledge, attitude and nursing practice of neonatal intensive care unit (NICU) nurses. Methods: Survey methodology using a self administered questionnaire was employed as the research design. A total of 153 questionnaires from 7 university hospital NICUs in Seoul, Daejeon, and Daegu were used for data analysis. Results: The percentage of correct answers on the breastfeeding knowledge questions for the NICU nurses was 59.3%. The nurses in NICU reported a somewhat positive attitude to breastfeeding, mean per item $3.70{\pm}0.41$ on a scale of 5 points. Their breastfeeding nursing practice was at a moderate level, mean per item, $3.26{\pm}0.74$. Breastfeeding knowledge had significant correlations with breastfeeding attitude (r=.554, p<.001) and nursing practice (r=.203, p=.002). Also, There was a significant correlation between breastfeeding attitude and nursing practice (r=.243, p=.002). Conclusion: These results suggest that breastfeeding educational programs and strategies for NICU nurses should be developed to increase their breastfeeding knowledge, attitude, and nursing practice.

Purpose: In this study an examination was done of the effects of a adolescent smoking cessation motivational program on smoking temptation, internal motivation, stage of smoking cessation and quit rate. The study was done with a nonequivalent control group pretest-posttest design. Methods: Participants in the experimental group were adolescents who smoked and were referred to the program by their high school teachers. They participated in the smoking cessation motivational program for 60 minutes per session, once or twice a week for six weeks. Participants in the control group were selected from the same age group within the school and the program was provided after the posttest was completed. t-test, Mann-Whitney test, and ${\chi}^2$-test were used to analyze data. Results: The level of smoking temptation, internal motivation and stage of smoking cessation had significant change in comparison to the pretest whereas the control group did not exhibit these changes. Conclusion: The results of the study indicate that a smoking cessation motivational program for adolescents is an effective strategy to increase smoking cessation motivation in adolescents, and can be utilized as an effective intervention for adolescents who smoke.

The purpose of this study was to evaluate the efficacy of the newly-developed $Qraypen^{TM}$ (All In One Bio, Korea) system for the diagnosis of early proximal caries by comparing it with the conventional methods of visual inspection and periapical radiography. This study was carried out from July 2015 to April 2016 targeting 32 children aged 7~12 years who visited Y-Dental Clinic for school oral health examinations. Two investigators selected and examined a total of 153 primary molars that had not undergone restorative treatment. Comparisons were carried out between visual inspections, readings of posterior periapical radiography images, and readings of $Qraypen^{TM}$ images. This study revealed that the percentage of interproximal surfaces of primary molar teeth without caries incidence was 83.7% using $Qraypen^{TM}$ imaging and 84.9% using visual inspection and periapical radiography. The differences between the two methods were not statistically significant. Thus, $Qraypen^{TM}$ is expected to be a useful and convenient auxiliary diagnostic device that can facilitate the detection of hidden proximal caries in primary molars.

Objectives : Characteristic symptoms, including hyperactivity and easy distractibility, in children with attention-deficit hyperactivity disorder (ADHD) suggest that their brain status, even at rest, might differ from that of healthy children. This study was conducted in order to determine whether resting state brain activity is compromised in medication-naive children with ADHD. Methods : Twenty medication-naive children with ADHD (mean age $10.3{\pm}2.5$) and 28 age- and gender-matched healthy volunteers (mean age $10.3{\pm}2.0$) underwent measurements for resting state brain activity using functional magnetic resonance imaging (fMRI). Among resting state related-independent components (RSICs) extracted from fMRI data using independent component analysis, a significant difference in RSICs was observed between groups, using a mixed Gaussian/gamma model. Results : Except for IQ, which was higher in the healthy control group, no demographic difference was observed between the two groups (p<.001). Significantly less activation of one RSIC, which includes the bilateral precuneus/posterior cingulate cortex, occipito-temporal junction, and anterior cingulate cortex, was observed in the ADHD group, compared with the control group (p<.05). Conclusion : An abnormal RSIC, posterior default mode network (DMN), was observed in the medication-naive ADHD group. Results of our study suggest that abnormality of posterior DMN is one of the main pathophysiologies of ADHD.

The purposes of the study are to examine the relationship amongst adolescents' internet usage, fandom activities, sense of community and their mental health in the digital era and to probe into the effect of internet usage, fandom activities, sense of community on adolescents' mental health. The results are as follows: First, there were statistically significant correlations among those four factors. Secondly, it shows that the effect of internet usage, fandom activities and sense of community on the adolescents' mental health have a difference by gender. In the case of female adolescents, there is no effect of internet usage on their mental health. But, the study reveals that adolescents' internet usage and fandom activities which now are accepted as a part of their culture, could be combined with the sense of community and could have an effect on the adolescents' mental health. Furthermore, the study casts a light on the possibility to build a strong point on adolescents' activities, education, counseling and policy making for the purpose to enhance adolescents' mental health in the future.

'Beauty and the Beast' was generated as a novel in 1740 and descended to date with the musical movie in 2017. This study is to understand what contents has been derived and expanded from one story for 277 years upon analyzing 'Beauty and the Beast' with the background of the times. Due to the limitation to include all the folktales and stories, the subjects of this study are limited with the contents that had been known and recorded as 'Beauty and the Beast.' 'Beauty and the Beast' has been expanded to 7 types of contents including novel, fairytale, movie, drama, animation, musical and film opera. It was created as a novel in the eighteenth century, made as a fairytale, and developed as a movie by Jean Cocteau, a movie director. With Industrial Revolution and the development of science, 'Beauty and the Beast' which derived into animation, drama, and musical contents, has been developed as the film opera thanks to the new trial of Philip Glass and the development of music industry. 'Beauty and the Beast' is still regenerating with a variety of contents continuously upon the development of computer technology and the fad of global remake. With anticipation of further analytical studies on 'Beauty and the Beast,' it is expected that the data of this study can be contributed as a reference in the other studies.

The purpose of this study was to compare and evaluate various hand functions in the most common position (chair sitting, standing, floor sitting) used by cerebral palsied children with spastic diplegia. The results, analysed statistically, could be useful in suggesting treatment strategy for the improvement of hand function in such patient. For this study, 27 children mild or moderate spastic diplegia were chosen. They were patients of the Rehabilitation Hospital, Yonsei University Medical Center. Both dominant and nondominant hands were tested by the Box and Block Test. Bilateral hand function was tested by bead striding and card sorting activities. Collected data was analysed using univariate correlation analysis and MANOVA. Results were as follows: 1) In chair sitting there was a significant positive correlation between dominant hand scores in the Bloc and Box Test and chronological age, gestation period, and time of treatment initiation. In bilateral hand function, card sorting scores correlated positively with time of treatment initiation. 2) In standing, there was a significantly positive correlation between dominant hand scores in the Block and Box Test and time of treatment initiation. 3) In floor sitting, there was a significantly positive correlation between the dominance hand scores in the Block and Box Test and the tine of treatment initiation. Bead stringing, a bilateral hand activity, correlated positively with gestation period and birth weight but negatively with the postnatal incubation period. 4) That score of children who walked showed no significant difference in any of the three postures. 5) Highest test scores in children who could nat walk were in the Box and Block Test for nondominant hand in bead stringing for bilateral hand function. There scores occurred with the children in thee chair sitting posture. The results showed that, in order to improve hand function in children with spastic diplegia, it is necessary to maintain a well supported upright trunk posture with variations allowed for relevance to the chosen position of thee improvements hand activity being performed.

Emotion in early childhood has been observed to make an important effect on behavioral development. The teacher has coached to develop good behavior based on considering emotional response rather than rational response. This study was to determine significance of emotional coaching for behavior development according emotion recognized by non-verbal measurement system developed specially in this study. The participants were 44 people and were asked to study in four experimental situation. The experiment was designed to four situation such as class without coaching, behavioral coaching, emotion coaching, and emotion coaching based on emotional recognition system. The dependent variables were subjective evaluation, behavioral amplitude, and HRC (Heart Rhythm Coherence) of heart response. The results showed the highest positive evaluation, behavioral amplitude, and HRC at emotion coaching based on emotional recognition system. In post-doc analysis, the subjective evaluation showed no difference between emotion coaching and system based emotion coaching. However, the behavioral amplitude and HRC showed a significant response between two coaching situation. In conclusion, quantitative data such as behavioral amplitude and HRC was expected to solve the ambiguity of subjective evaluation. The emotion coaching of teacher using emotional recognition system was can be to improve positive emotion and psychological stability for children.

Tooth anklylosis is defined as the adhesion state of alveolar bone to dentin or cementum. Trauma, disturbed metabolic disease, and congenital disease have been given as etiologic factors. Complications of tooth ankylosis are tipping of the neighboring teeth, space loss, and supraeruption of the opposing teeth. Particularly if dental ankylosis occurs in maxillary incisors of a growing child, the ankylosed tooth can not move vertically with subsequent disturbance in vertical growth of the alveolar process. With an appropriate treatment approach, an esthetic condition must be achieved especially in the maxillary anterior region. In this report, two cases are presented which were treated by the surgical repositioning method. One is treated by alveolar bone distraction osteogenesis which used a tooth-borne type distraction device and the other by single tooth osteotomy.
