This study aimed to identify binge-eating behavior and food addiction in Korean population and to determine their associations with obesity, eating behaviors, mental health and cognitive characteristics. We collected clinical questionnaire scores related to eating problems (e.g. binge eating, food addiction, food cravings), mental health (e.g. depression), and cognitive functions (e.g. impulsivity, emotion regulation) in 257 Korean adults in the normal and the obese weight ranges. Binge-eating and food addiction were most frequent in obese women (binge-eating: 46.6%, food addiction: 29.3%) when we divided the participants into 4 groups depending on gender and obesity status. The independence test using the data with propensity score matching confirmed that binge-eating and food addiction were more prevalent in obese individuals. Finally, we constructed the logistic regression models using forward selection method to evaluate the influence of various clinical questionnaire scores on binge-eating and food addiction respectively. Binge-eating was significantly associated with the clinical scales of eating disorders, food craving, state anxiety, and emotion regulation (cognitive reappraisal) as well as food addiction. Food addiction demonstrated the significant effect of food craving, binge-eating, the interaction of obesity and age, and years of education. In conclusion, we found that binge-eating and food addiction are much more frequent in females and obese individuals. Both binge-eating and food addiction commonly involved eating problems (e.g. food craving), but there was difference in mental health and cognitive risk factors. Therefore, it is required to distinguish food addiction from binge-eating and investigate intrinsic and environmental risk factors for each pathology.

This study was conducted to examine the reliability and validity of the internet (IOS-Q), Game (GOS-Q), and Smartphone (SOS-Q) Overuse Screening Questionnaires in a large community sample of adolescents. To achieve this goal, data from 9,336 middle school students (male: 4,796, female: 4,540) was divided into two groups and analyzed by conducting confirmatory factor analysis and exploratory factor analysis, respectively. We conducted another confirmatory factor analysis on a separate sample of data from 4,536 elementary school students (male: 2,260 male, female: 2,276) and 6,551 middle school students (male: 3,013, female: 3,538) from other populations. As a result of factor analysis, IOS-Q was consisted of 17 items, GOS-Q was consisted of 19 items, and SOS-Q was consisted of 18 items. The IOS-Q and GOS-Q factors were psychological dependence, failure to control use despite recognizing problems, dangerous use, and reduced interest in other areas while the SOS-Q factors were dangerous and obsessive use, failure to control use despite recognizing problems, reduced interest in other areas, and withdrawal/tolerance. Each factor reflected the major facets of behavioral addiction or impulse control disorder, and the questionnaires had good internal consistencies of .880-.915. Latent profile and ROC analyses were conducted to determine cutoff points for screening high-risk groups. Lastly, theoretical and practical implications as well as the limitations of this study were discussed.

Objectives : The purpose of this study was to quantitatively assess the degree of Graves' Disease affecting mental health through the results of multiphasic military personality inventory (MPI) in 19-year-old men. Methods : We collected and analyzed the results of the MPI for 592 healthy subjects and 148 Graves' disease patients among the 19-year-old men who visited the Military Manpower Administration from February 2008 to January 2010. Results : Among demographic characteristics, both Graves' disease and control group are 19-year-old men. Educational level, socioeconomic status, parental relationship, and BMI were not statistically different between the two groups (χ²=0.089, p=0.766; χ²=5.090, p=0.278; χ²=5.988, p=0.112 ; t=-0.635, p=0.526). In the MPI, among validity scales, the score of the faking-good subscale was significantly lower in the Graves' group (t=3.507, p<0.001), but in the faking-bad and infrequency subscales scores were not significantly different between two groups (t=-1.700, p=0.090; t=-0.519, p=0.604). Among the neurosis scale, anxiety, depression, somatization, and personality disorder subscale scores were all significantly higher in Graves' disease group (t=-3.323, p<0.001; t=-4.210, p<0.001; t=-6.202, p<0.001; t=-2.872, p<0.01). Among the psychopath scale, each score of schizophrenia and paranoia subscales were not statistically different between the two groups (t=-0.158, p=0.874; t=-0.846, p=0.398). Conclusions : According to MPI result, we can confirm that Graves' disease patients in 19-year-old-men may appear features such as anxiety, depression, somatization and personality tendency (introversion or impulsivity) than the control group.

Objectives：This study was conducted to compare the clinical and neuropsychological characteristics by DSM-IV subtypes of attention deficit hyperactivity disorder(ADHD) patients who did not have comorbid psychiatric disorders. Methods：5-15 year old children with ADHD were recruited at psychiatric outpatient clinic of Yeungnam University hospital and the patients with comorbidity or neurological abnormalities were excluded. Finally, total 404 children with ADHD were selected for this study. There were 234 subjects of ADHD-C(57.9%), 156 subjects of ADHD-I(38.6%) and 14 subjects of ADHD-HI(3.5%), who fulfilled the DSM-IV diagnostic criteria. The mean age of the total subjects was 9.63±2.49 years old. The psychopathology, IQ, behavioral problems, neuropsychological executive function were evaluated before pharmacological treatment. The measures were Korean Personality Inventory of Child(K-PIC) for psychopathology, 4 behavioral check lists(ADDES-HV, ACTeRS, CAP, SNAP) for behavioral symptoms of ADHD, K-ABC and KEDI-WISC for IQ and Conner's CPT, WCST, SST for neuropsychological executive functions. Results：1) The prevalence of subtypes was ADHD-C, ADHD-I, ADHD-HI in decreasing order. There was no sex difference of prevalence among three subtypes. The mean age of ADHD-I was older than other subtypes. 2) There was significant differences of psychopathology among subtypes, the ADHD-C and ADHD-HI had higher than the ADHD-I in the scores of delinquent, hyperactivity and psychosis；the ADHD-C had higher than the ADHD-I in the scores of family relation and autism, the scores of ego resilience were lower than the ADHD-I. However, there was no difference in anxiety, depression and somatization scores among them. 3) The results of behavioral symptom check lists, the ADHD-C had higher the score of inattention, hyperactivity and impulsivity than the ADHD-I. Meanwhile the results of ACTeRs, which rated by the teachers, were different. 4) There were significant differences of sequential processing scale and arithmetics among subtypes in IQ using K-ABC, but there was no significant difference between the ADHD-C and the ADHD-I after excluding the ADHD-HI due to small numbers. 5) There was numerical difference among subtypes but did not reach statistical significance in three neuropsychological executive function tests. Conclusion：In conclusion, our results revealed that there was significant difference in clinical features among three subtypes but, no significant difference in executive functions.

This study aimed increase the quality during ripening of Cheddar cheese made with proteinase-negative mutant of Streptococcus lactis KCTC 1913 selected by curing. The degradation of protein during cheese ripening were investigated by electrophoresis and chromatography. The results were summarized as follow ; 1. The number of lactic acid bacteria decreased with the ripening stage, and that of the control cheese decreased faster than that of the cheese made with mutant. 2. Polyacrylamide gel electrophoretic analysis of cheese caseins revealed no difference between the cheese made with mutant and the control cheese, but differences along with the ripening stage were evident. 3. On Sephadex G-25 column chromatography, the extracts of bitter components from the green cheese and 3 month ripended cheese were fractionated into 3 fractions. With the progress of ripening, bitter peptides were degraded to rather small peptides or free amino acids. 4. Sensory evaluation of the 3 month ripended Cheddar cheese found no significant differences in color but the cheese made with mutant evidenced higher palatability in flavor and better texture than the control cheese. 5. The yields of the cheddar cheese made with mutant was 0.14% higher than that of the control cheese.

This study was to know the influence of familial environment and moral development on conduct disorder. Subjects were composed of 47 male and female patients with conduct disorder(patients group), 113 general male and female students(normal group), and 173 juvenile prisoners(JP group). The Korean Form of the Family Environment Scale(FES) was used to assess the family environment of the subjects and the Korean Defining Issues Test(DIT) was used to assess the moral development. Conduct disorder was diagnosed with the DSM-III-R criteria for conduct disorder. The influence of familial environment and moral development on conduct disorder was analyzed with ANOVA and the differences among groups were verified with Scheffe test. There was no difference in the socioeconomic status and the physical abuse by the parents among the three groups. But the rates of divorce or separation of the parents were significantly highest in the JP group and higher in the patients group than in the normal group. Especially the subjects of the JP group experienced the divorce or separation of their parents during the preschool or the elementary school periods. In regard to the family environment, there was no difference among the three groups in the Subscales of Expressiveness, Independence, Intellectual-cultural orientation, Moral-religious emphasis, Organization, and Control. ‘Cohesion Subscale’ was significantly higher in the normal group than in the JP group. ‘Conflict Subscale’ was significantly higher in the JP and patients groups than in the normal group. ‘Achievement orientation Subscale’ was significantly lower in the JP group than in the patients and normal groups. ‘Activerecreational orientation’ was significantly lower in the normal group than in the JP and patients groups. In gegard to the moral developmental stage, the lower moral developmental step was higher in the JP and patients groups than in the normal group. The higher steps were significantly higher in the normal group than in the JP group. There was no significant correlation between the degree of ‘Moral-religious emphasis Subscale’ and the moral development. The clinical implication and limitation of present study were listed and discussed.

The purpose of this study was to investigate the PAI profile of the beauty major students. They were used through the PAI inspection result of 298 university students located in the chungcheong province in 2019. The results are summerized as follows; First, when comparing the average scale of college students majoring in beauty with those of college students majoring in general, college students majoring in beauty displayed a higher profile type in clinical scale than those of university students in general, with significant differences in SOM and ALC. Second, SOM, PAR, AGG, SUI that were significant when comparing beauty majors and general majors to navigate the PAI scale that significantly predicts beauty majors. As a result of conducting stepwise regression analysis on the four factors as a search factor, the scale of SOM is extracted, and it becomes a diversion that can predict college students in the beauty major. Therefore, beauty majors are more obsessed with physical problems than the ordinary students, and have an impulse-oriented behavior. These results will be used as materials for selecting, managing, educating or consulting a student majoring in beauty and will provide many implications for career choices after graduation.

Objectives：Body image is closely related to self-esteem and weight-control related behaviors. In particular, relationship between two factors would be stronger in female adolescents. False recognition on body image and weight can be a risk factor of eating disorder, depression, and suicidal ideation. This study aimed to examine the effects of body image and eating disorders on developing depressive symptoms and suicidal ideation in female adolescents. Methods：Two hundred thirty nine students of a Girls' Commercial High School in Seoul were recruited. Eating Attitude Test for Korean Adolescents, Self-Esteem Scales, Impulsiveness Scale, Beck's Depression Inventory and Beck's Suicidal Ideation Scale were used to measure eating attitude and severity of psychiatric symptoms. Results：Among 239 subjects, the estimated risk group of eating disorders was 10%(n=24). They experienced more depressive symptoms than the control group. The bigger discrepancy in current and ideal body mass index was significantly related with higher depressive mood, suicidal idea, abnormal eating habits and lower self-esteem. Discrepancy between current and idea BMI was the most meaningful predictive factor about depression and suicidal thoughts by linear regression analysis. Conclusion：In spite of normal weight range of enrolled subjects, they experienced significant depressive mood, suicide thoughts and lower self-esteem associated with the discrepancy of their own subjective body image and current body mass index. Hence educational approach regarding normal body image and healthy weight control is needed for their mental health and preventing eating disorder.

Korea has the highest suicide rate among Organization for Economic Cooperation and Development countries, with increasing rates observed among children and adolescents with low levels of life satisfaction. Patients in these age groups exhibit particularly turbulent and impulsive behaviors, which make suicide highly contagious and fatal. The loss of meaningful work or activities increases the risk of suicide, especially in young people. Following revisions to the Mental Health Welfare Act (2016), which has included occupational therapists among mental health professionals, a multidisciplinary approach including occupational therapy has been emphasized upon in mental health services. Screening tools for preventing suicide in children and adolescents include the Suicidal Ideation Scale, Beck's Suicidal Ideation Scale, Columbia-Suicide Severity Rating Scale, Reasons for Living Scale for Adolescents, and the Student Emotional and Behavioral Characteristics Test. The Canadian Occupational Performance Measure, which is an occupational therapy evaluation tool, is also used. Various suicide prevention programs have been proposed across academic disciplines; however, due to the urgent nature of high-risk groups, there is a need for timely services. Currently, most existing programs focus primarily on the cognitive-behavioral aspects. In this study, we aimed to introduce diverse suicide prevention programs for mental health professionals working with high-risk children and adolescents in order to equip them with the relevant information and help apply their learnings effectively in different situations.
