Objectives : This study aimed to investigate the validity and standardize the Spielberger State-Trait Anxiety Inventory (STAI) in middle and hi? school students and find the factors which influenced their anxiety. Methods : 1,033 middle and hi? school students were selected randomly from 7 regions around the country. The State-Trait Anxiety Inventory (STAI) was applied in all subjects and the Beck Anxiety Inventory (BAI) was applied with it to calculate the coexistence validity. To find the causes of adolescent anxiety, Beck Depression Inventory (BDI), Subjective Happiness Scale, The Satisfaction With Life Scale, Rosenberg Self-Esteem Scale (RES), Parent-Adolescent communication family inventories, In family social scene were all applied and correlation with STAI was investigated. Results : Reliability issues, such as internal coherence, the coherence between specific phobia and anxiety state were Satisfactory and the coexistence validity with BAI was high. The result of factor analysis shows that factor structures were similar to previous studies. High school students showed higher anxiety levels than middle school students, and girls higher than boys. For socio-economical factors, Poverty and poor grades related to higher anxiety. Among psychological factors, happiness and Self-esteem showed high correlation wi anxiety. Conclusion : The State-Trait Anxiety Inventory (STAI) showed high validity and reliability in middle and hi? school students and proved itself a reliable scale. When treating their anxiety, age, sex, socio-economical and psychological factors should all be considered.

Objective The effect of acute noise on cognitive function has long been a topic of study, yet these effects remain a serious problem for learning performance in school children. Methods From November 15, 2010 to December 8, 2010, we enrolled 268 students from three elementary schools (135 boys and 133 girls, 10–12 years old) in Ulsan, Korea. The study subjects were divided into two groups according to their test conditions (background versus additional noise), and tests were conducted using psychological examination tools. Chi-square tests and general linear models were used to assess the differences of impacts on cognition between the two groups. Results After adjusting for socio-demographic covariates, the noise significantly affected the results of full-scale IQ, verbal IQ, Continuous Performance Test scores, and Children’s Color Trails Test and Stroop test scores. The groups at high risk of learning difficulties were more affected by noise than low-risk groups. Conclusion These findings suggest that noise is hazardous to the attention and performance of elementary school students, particularly for groups at greater risk for poor academic achievement. Additional studies are needed to identify subject-specific levels of noise that can affect attention and cognitive function.

Objectives:This study examined the prevalence of psychiatric problems in children with scholastic difficulties who had been referred for mental health services from the Office of Education in Ulsan Metropolitan City. Methods:Child psychiatrists evaluated the referred children using the DSM-IV. Evaluation tools included the Wechsler Intelligence Scale for Children-III, the Children’s Depression Inventory, the Korean form of the State-trait anxiety Inventory for children, the ADHD rating. Results:Seventy-six children consisting of 64 boys (84.2%) and 12 girls (15.8%) participated in the study. The average age was 10.3 (SD=0.93) years old. Approximately 74% of the children referred for scholastic difficulties were diagnosed with mental retardation. The Axis I diagnosis among these children were ADHD (86.8%), depression (21.1%), learning disorder (9.2%), communication disorder (4.8%), pervasive developmental disorder (3.6%), internet addiction (1.3%), and mood disorder (1.3%). Their overall measure according to the Child Depression Inventory was 22.7 (SD=16.8), that for the State-Trait Anxiety Inventory for Children was 33.3 (SD=7.9)/32.4 (SD=9.5), and that for the ADHD rating scale was 18.9 (SD=10.9). Conclusion:These results suggest that many children with scholastic difficulties have both complex psychiatric and educational problems.

Objectives:This study was conducted to investigate the prevalence of victims of bullying and the demographic characteristics of victims, and their related psychopathology, in a Korean nationwide sample of youths in middle and high school over a one month period. Methods:During the autumn of 2009, students in the 7th to 12th grades at 23 secondary schools participated in a nationwide, cross-sectional study. The study subjects completed the Adolescent Mental Health and Problem Behavior Screening Questionnaire-II (AMPQ-II) and Symptom Checklist-90-Revision (SCL-90-R). Based on the data acquired, descriptive statistics, correlation coefficients and multiple logistic regression analysis were performed. Results:Among the 3364 participants, 2272 (67.54%) completed the questionnaire. The prevalence of victimization was 28.9%. Male gender was positively associated with victimization, and grade level was negatively related to victimization. The AMPQ-II bullying score (Factor 4) was significantly (p<.001) and positively correlated to the AMPQ-II student total score (r=0.50), Worry and thought (Factor 1 ; r=0.38), Mood and suicide (Factor 2 ; r=0.31), Academic and Internet-related problems (Factor 3 ; r=0.24), Rule violations (Factor 5 ; r=0.23), and AMPQ-II teacher total score (r=0.11). Somatization (r=0.23), Obsessive-compulsive behavior (r=0.24), Interpersonal sensitivity (r=0.30), Depression (r=0.33), Anxiety (r=0.26), Hostility (r=0.30), Phobic anxiety (r=0.22), Paranoid ideation (r=0.36), and Psychoticism (r=0.31) results from the SCL-90-R were also found to be positively related to the AMPQ-II bullying score, and remained significant after adjusting for age and gender. A total of 26% of the victims reported suicidal ideations as compared to 9% of non-victims over the month prior to the evaluation (χ2=119.595, df=1, p<.001). The multiple logistic regression analysis indicated that the AMPQ-II bullying score significantly increased the risk of suicidal ideation [Exp(b)=1.55, df=1, p<.001] after adjusting for age and gender. Conclusion:School bullying was highly prevalent among Korean middle and high school students. This study provided strong evidence that suicidal ideation and psychopathology were serious problems among the victims of bullying.

Objectives:The purposes of this study were to develop a mental health screening questionnaire and the practical intervention programs or guidelines which can be used in middle and high schools by students and teachers. Methods:The Adolescent Mental health & Problem behavior Screening Questionnaire II (AMPQ-II) was developed and was tested for reliability and validity using nationwide data from 2,180 middle and high school students and 2,145 teachers. Results:The AMPQ-II was measured by both students and teachers. The correlation coefficient of the test-retest test was 0.567 and internal consistency was high (Cronbach?s alpha=0.878). Five factors such as worry and thought, mood and suicide, academic and Internet-related problems, peer problems, and rule violations were proposed. We also developed a practical guideline and manuals which can be easily used by secondary school teachers to screen for and manage mental health problems at school. Conclusion:The AMPQ-II can be a useful and reliable tool to screen for mental health problems in middle and high schools in South Korea.

N/A Background/Aims: Chronic gastrointestinal (GI) symptoms are believed to be common in the general population, but there is a lack of data from Korea. The aim of this study was to es1imate the prevalence of chronic gastrointestinal symptoms in a rural community in Korea by using the Bowel Symptom Questionnaire (BSQ), which was based on the multinational diagnotic Rome criteria for functional bowel disorders, as a measure of GI symptoms. Methods: A cross-sectional survey, using a reliable and valid questionnaire based on the fulfillment of the Rome criteria, was performed in a densely populated district in a Korean rural community on the residents aged l8-69 yr (mean 48±14 yr). 95,5% responded (n=420). All respondents were interviewed at their home or offices by a team of interviewers. Results: Two thirds of Korean rural residents experience gastrointestinal symptoms and one fifth of them visit a clinic or hospital at least once a year. Prevalences of weekly heartburn, gastroesophageal reflux disease, dyspepsia, irritable bowel syndrome (IBS), and chronic constipation were 5.2% (95% confidence interval [CI], 3.l-7.4, 2.6% (95% Cl, 1.1-4.2), 15.5% (95% CI, 11.9-19.0), 8.6% (95% CI, 3.8-11,3), and 24.3% (95% CI, 20.1-28.5) respectively. The prevalence of dyspepsia was 25%, taking medication usage into consideration. Ulcer-like dyspepsia (11.2%) was the most common subtype and 40% of the subjects with dyspepsia were classified into more than one subtype of dyspesia. There was an overlap between subjects with IBS and dypepsia with 6.1% of dypeptics having IBS and ll,l% of IBS patients having dypepsia. Conclusions: The prevalence of GERD was low in Korea compared with that of the Western countries. The prevalences of dyspepsia and IBS were similar to those of the Western countries. The most common gastrointestinal symptom in a rural community in Korea is dyspepsia, (Korean Journal of Castrointestinal Motility 2000;6:31-43)

연구목적 : 청소년 범죄에서 정신건강의 문제와 범죄가 관련성이 높다는 것은 잘 알려져 있지만 국내에서는 아동청소년 범죄자들의 정신건강에 관한 연구가 거의 없다. 뿐만 아니라 아동청소년정신건강 영역에서 기계학습을 적용한 연구는 아직 초기단계이다. 본 예비연구에 서는 여자청소년 재소자들에서 정신건강 문제 중 우울증의 예측에 기계학습 알고리즘을 적용하여 적합한 지를 알아보고자 한다. 방 법 : 대상자는 청주소년원에 재소중인 87명의 여자청소년을 대상으로 하였다. 대상자들에게 설문지 패키지 (인구학적 정보, 범죄관련 정보, 자기보고척도 설문지(아동기부정적경험 설문지, 벡우울척도)를 배부하여 정보를 수집하였다. 기계학습 기법을 이용하여 수집된 재소자들의 기본 정보를 바탕으로 우울증을 예측할 수 있는 6개의 모델(Logistic regression, Random forest, Supportive vector machine, Decision tree, Nearest neighbor, Adaboost)을 생성하여 각 모델간의 예측 성능을 비교해 보았다. 결 과 : 대상자를 벡우울척도(절단점 13)로 군을 분류한 결과 정상군 18명(21%)과 우울증군 69명(79%)이었다. 6개 모델의 우울증 예측 정확도는 Logistic regression 81.8%, Random forest 81.8%, Supportive vector machine 68.18%, Decision tree 72.7%, Nearest neighbor 77.3%, Adaboost 63.6%였다. 그중에서 Random forest 모델의 AUC score는 0.75로 다른 모델들과 비교하여 가장 높았다. 결 론 : 본 연구는 재소청소년의 정신건강에 중점을 두어 현황을 파악하고,우울증의 예측에 기계학습 기법을 적용을 하여 높은 정확도를 확인하였다는 점에서 의의가 있다. 또한 취약계층의 정신건강 영역에 기계학습 기법을 적용하여 관리 및 감시에 적용 가능성에 대한 근거를 제공하였다. Objectives : It is well known that mental health problems and crime are highly related to youth crime, but there is little research on the mental health of young offenders in Korea. Furthermore, research on the application of machine learning in the mental health of children and adolescents is still novel. This preliminary study aims to investigate whether it is appropriate to apply machine learning algorithms to predict depression among female adolescent inmates. Methods : The subjects were 87 young females in Cheongju Juvenile Center. A questionnaire was distributed to the subjects to gather their demographic information and crime-related information, as well as their adverse childhood experiences and Beck depression inventory scores using self-reported scale questionnaires. Based on the collected information, six models (logistic regression, random forest, supportive vector machine, decision tree, nearest neighbor, Adaboost) that can predict depression were created to compare the predictive performance between models using machine learning techniques. Results : Results showed that 29 victims (25.7%) met the criteria of PTSD and 19 victims (16.8%) met the rigid criteria of PTSD. But, according to the subscales, 41 victims (36.3%) were diagnosed as PTSD. Victims with PTSD had more serious depression, anxiety, sleep disturbance, anger, social withdrawal and life stresses. Conclusion : This study identified the current mental health status of female inmates with high accuracy by applying machine learn-ing techniques to predict depression. The applicability of machine learning techniques to the management and surveillance of mental health in vulnerable groups was also highlighted.

Objective The purpose of this study was to examine the effects of the Soma experiencing motion (Soma e-motion) program on interoceptive awareness and self-compassion among novices. Methods A total of 19 adults (clinical group=9, non-clinical group=10) participated in the intervention. Psychological and physical changes after program were qualitatively analyzed using in-depth interviews. The Korean Multidimensional Assessment of Interoceptive Awareness (K-MAIA) and the Korean version of the Self-Compassion Scale (K-SCS) were used as quantitative measures. Results The non-clinical group showed statistically significant differences in the K-MAIA scores (z=-2.805, p<0.01) and K-SCS scores (z=-2.191, p<0.05); however, the clinical group showed no significant differences (K-MAIA: z=-0.652, p>0.05; K-SCS: z=-0.178, p>0.05). According to the in-depth interviews, the results of the qualitative analysis were categorized into five dimensions (psychological and emotional, physical, cognitive, behavioral, and aspects participants found challenging and needs improvement). Conclusion The Soma e-motion program was feasible for improving interoceptive awareness and self-compassion in the non-clinical group. However, further research is needed to investigate the clinical efficacy of the Soma e-motion program for clinical group.

Locally Delivered Growth Factor Enhances the Angiogenic Efficacy of Adipose-Derived Stromal Cells Transplanted to Ischemic Limbs

Bhang, Suk Ho,Cho, Seung-Woo,Lim, Jae Min,Kang, Jin Muk,Lee, Tae-Jin,Yang, Hee Seok,Song, Young Soo,Park, Moon Hyang,Kim, Hyo-Soo,Yoo, Kyung-Jong,Jang, Yangsoo,Langer, Robert,Anderson, Daniel G.,Kim, Wiley (John WileySons) 2009 Stem Cells Vol.27 No.8

<P>Ischemia is a potentially fatal medical event that is associated with as many as 30% of all deaths. Stem cell therapy offers significant therapeutic promise, but poor survival following transplantation to ischemic tissue limits its efficacy. Here we demonstrate that nanosphere-mediated growth factor delivery can enhance the survival of transplanted human adipose-derived stromal cells (hADSCs) and secretion of human angiogenic growth factors per cell, and substantially improve therapeutic efficacy of hADSCs. In vitro, in hypoxic (1% oxygen) and serum-deprived conditions that simulate in vivo ischemia, fibroblast growth factor-2 (FGF2) significantly reduced hADSC apoptosis and enhanced angiogenic growth factor secretion. In vivo, hADSCs delivered intramuscularly into ischemic hind limbs in combination with FGF2 resulted in significant improvements in limb survival and blood perfusion, as well as survival of the transplanted hADSCs and secretion of human angiogenic growth factors (i.e., vascular endothelial growth factor, hepatocyte growth factor, and FGF2). Interestingly, the majority of transplanted hADSCs were localized adjacent to the microvessels rather than being incorporated into them, suggesting that their major contribution to angiogenesis might be to increase paracrine secretion of angiogenic growth factors. This study demonstrates the potential of hADSCs in combination with growth factors for use in the treatment of ischemia.</P>
