As smartphone usage has increased recently, so has smartphone addiction. Many of the smartphone users, however, do not even recognize the risk of smartphone addiction. In this experiment, smartphone users have been categorized into two groups by smartphone addiction measure (S-measure) developed by 2011 National Information Society Agency (NIA): A high risk group and a normal group. The changes of brain waves have been observed when the subjects were watching emotional videos of anger, sadness, happiness, and fear. The results show that the values of FP1 and FP2 (frontal lobe) theta band of the high risk group have been measured to be high, which indicate anxiety disorder. Although happiness and fear videos showed no difference between these groups, sadness and anger videos showed significantly different results for these groups: the brain waves of the high risk group showed higher values than those of the normal group. Therefore, this experiment showed that the high risk group takes feelings of sadness and anger more sensitively than the normal group.

This study investigated the relationships between eating disorder risk, body image perception, weight control, and dietary habits in Korean women. Body shape perception, the Eating Attitude Test (EAT-26) and dietary habit information were collected by a self-administered questionnaire to 373 adult women and the data were analyzed by the Chi-square test. 31.4% of the women were classified in the eating disorder group by a score of over 20 points on the EAT-26. Compared to the normal group, more women in the eating disorder risk group perceived that a thin body shape was the ideal body shape and were dissatisfied with their body shape. This group was also more interested in weight control and more likely to try weight control methods. The eating disorder risk group was more likely to skip meals and snacks than the normal group. In addition, they had a greater appetite and a higher frequency of overeating than the normal group. Over 30% of the Korean women surveyed were categorized at high risk of eating disorders. They were more likely to overestimate body weight and shape and tried to control their weight by inappropriate methods. To prevent eating disorders in adult women, nutrition education programs should incorporate strategies to change inaccurate self-body image and to disseminate information about healthy weight control methods.

This study investigated the clinical characteristics of the Internet addiction risk group using MMPI-2 and discussed whether the MMPI-2 can be used for diagnosis, evaluation and intervention of the Internet addiction risk group. We verified the difference in the MMPI-2 scales between the addiction-risk group and the general user group, and verified whether the substance-related scales MAC-R, AAP, and AAS scales can distinguish between Internet addiction risk group and general users. The results of the analysis of the MMPI-2 characteristics of 39 Internet addiction risk group and 21 general user group who visited internet addiction counseling center showed significant difference in the D, Pa, Pt, Sc, and Si scales on the clinical scale. There was no difference in the MAC-R, AAS, and APS scales between the Internet addiction group and the general user group. This suggests, that it is not possible to screen the Internet addiction risk group with the supplementary measure, and it is necessary to develop a new scale to diagnose internet addiction.

This study analyzed the influence of smartphone addiction on adaptation to school life by using the questionnaire survey method of 431 students of radiological science in six regions. The results showed that 89.6% of students are the general user group, 6.3% the high risk group and 4.2% the potential risk group. Adaptability to school life was found to be social adaptability 3.71, righteous adaptability 3.17 and academic adaptability 2.95. Academic adaptability was 3.06 for male students and 2.79 for female students. And righteous adaptability was 3.26 for male students and 3.03 for female students. As a result, male students were more adaptable than female students in academic adaptability and righteous adaptability, which was statistically significant. And Social adaptability was 3.73 for female students and 3.68 for male students, but there was no significant difference(p<.001). Adaptability to school life by smartphone addiction level was found to be the general user group 3.19, the potential risk group 3.05 and the high risk group 2.81. The difference of righteous adaptability between the general user group and the high risk group was statistically significant. And social and academic adaptability of the general user group and the high risk group was no significant(p<.01).

This study explored resilience and protective factors in children at-risk. Teachers of 755 children in child care centers replied to questionnaires regarding resiliency and behavior problems; children's mothers replied to questionnaires about risk factors, own parenting, and family hardiness. The data of 216 vulnerable children and 355 children in a comparative group who had not been exposed to any risk factors were analyzed. Findings showed that resilience was differentiated by gender and age; that is, resilience in the vulnerable group covaried as a function of gender and age. The resilience level of the vulnerable group was lower than the comparative group. Children with fewer behavior problems had a higher level of resilience, and resilience was higher for vulnerable children with higher levels of protective factors.

This study was conducted to investigate the association between initial nutritional status and treatment outcome of hepatoma patients. Initial nutritional status was measured based on weight, serum albumin and total lymphocyte counts. Treatment outcome was measured in the three categories such as complication, treatment status at discharge and mortality. The study subjects were 120 patients with hepatoma cancer admitted at a university hospital in Seoul. The information about initial nutritional status and treatment outcome was collected from medical records. Chi-square test was used to test the association between initial nutritional status and treatment outcome As a result. 76.6% of the subjects were classified as the nutritional risk group based on initial nutritional states. Prevalence of complication was higher in nutritional risk group I and II than that in non-risk group(p<0.05). Death rare of the nutritional risk group was significantly higher than that of non-risk group(p<0.001). The findings suggest the strong association between the initial nutritional status and treatment outcome of hepatoma cancer.

Purpose: The purpose of this study was to identify factors associated with high risk drinking in adults. Methods: Multi-variate logistic regression was used to analyze the data of 15,949 adults age 19 years or older from the sixth (2013-2015) Korea National Health and Nutrition Examination Survey. Results: Factors associated with high risk drinking included education level, employment and smoking status among the age group of 19-39. In the 40-59 year age group, the associated factors were gender, employment, smoking, obesity, and depressive mood. In the over 60 year age group, related factors included gender, employment, smoking, abdominal obesity, and subjective health status. Conclusion: The result of this study suggests that early risk factor screening may be helpful to avoid the progression to high-risk drinking. An individualized approach for each age group can be used as a preventive measure.

The purpose of this study is to examine children's/adolescents' motives for playing internet games and adaptation to school in accordance with their frequency levels of playing internet games. Participants were 236 children from grades 4, 5, and 6 in two elementary schools and 237 adolescents from grades 1, 2, and 3 in one middle school. They were measured on frequency levels of playing internet games, motives for playing internet games, and adaptation to school. Collected data were analyzed by SPSS WIN 12.0 for reliability, frequency, Chi-square test, t-test, Pearson's correlation, and one way ANOVA. Major findings of the research are as follows: First, children's/adolescents' frequency levels of playing internet games differed by their gender. The male ratio was much higher than the female ratio in the potential risk group and the high risk poop. In contrast, no grade differences on the frequency levels of playing internet games were found. Second, children's/adolescents' motives for playing internet games differed by their gender. Especially, among the motives the greatest difference between male and female was marked for 'Social Relationship'. Third, children's/adolescents' motives for playing internet games differed by their frequency levels of playing internet games. For 'Conformity,' the low risk group differed from the high risk group. For 'Spending Time', 'Benefit', 'Competition', and 'Social Relationship', the low risk group differed from the potential risk group and also from the high risk poop. Fourth, children's/adolescents' adaptation to school differed by their frequency levels of playing internet games. The high risk group exhibited a low level of adaptation in 'Academic Activities', 'a subcategory of adaptation to school.

Cardiotoxicity assessment of all drugs has been performed according to the ICH guidelines since 2005. Non-clinical evaluation S7B has focused on the hERG assay, which has a low specificity problem. The comprehensive in vitro proarrhythmia assay (CiPA) project was initiated to correct this problem, which presented a model for classifying the Torsade de pointes (TdP)-induced risk of drugs as biomarkers calculated through an in silico ventricular model. In this study, we propose a TdP-induced risk group classifier of artificial neural network (ANN)-based. The model was trained with 12 drugs and tested with 16 drugs. The ANN model was performed according to nine features, seven features, five features as an individual ANN model input, and the model with the highest performance was selected and compared with the classification performance of the qNet input logistic regression model. When the five features model was used, the results were AUC 0.93 in the high-risk group, AUC 0.73 in the intermediate-risk group, and 0.92 in the low-risk group. The model's performance using qNet was lower than the ANN model in the high-risk group by 17.6% and in the low-risk group by 29.5%. This study was able to express performance in the three risk groups, and it is a model that solved the problem of low specificity, which is the problem of hERG assay.
