In this study, characteristics of the problem solving process of the balancing redox equations was ana-lyzed by mental capacity and problem solving methods, and the pertinent teaching and learning guidance for oxidation-reduction unit was suggested. Participants were 79 senior high school students and 57 science high school students. Tests were conducted to measure the mental capacity, the understanding of the oxidation-reduction concepts and the com-pletion of the balancing redox equations. The framework was made to find the patterns of failure and success. As the analysis of the influence on the performance of mental capacity,understanding of the oxidation-reduction concepts, and problem solving methods, students who had lower understanding of oxidation-reduction concepts selected the trial and error method, and their performance were influenced by mental capacity. The students that had higher understanding of the oxidation-reduction concepts had good performance by using oxidation number method regardless of their mental capacity. As the results of analysis for the patterns, the success patterns of solving the problems, those of mostly the sci-ence high school students, were the cases of using oxidation number method well and lessening problem solving steps. The patterns of failure in solving problems by using trial and error method showed that students had mistakes in cal-culating, errors in making unknown equations, no consideration for all variables, or stopped solving the complicated problems. The patterns of failure in solving problems by using oxidation number method showed that many students had wrong oxidation number or no consideration for mass and charge balance.

Present study investigated the relationship between children's psychiatric disorders and their mothers' psychological problems. Ninety-one psychiatric outpatients from a children's hospital were classified into three diagnostic groups - internalizing symptom group(n=35), externalizing symptom group(n=35), and developmental disorder group(n=21) - based on their psychiatric problems. A normal control group was formed by matching on the age and education of mothers. Mothers' MMPI profiles which were classified into five types - normal, depression, anxiety disorder, somatization disorder, and personality disorder - were examined in relation with children's diagnoses. The profiles of the mothers in the normal control group were mostly normal, while depressive profiles were dominant among those of the clinical groups regardless of the children's diagnoses. Therefore, the data implied association between children's psychiatric problems and their mothers' psychological problems. A possibility of negative reciprocal interactions between children and their mothers was discussed. It was also suggested that further research need to examine the specific effects of children's psychiatric problems on the psychological adjustment of their mothers, as well as the effects of parental psychiatric problems on the adjustment of their offsprings.

Chronotype (CT) is defined as an inter-individual difference in sleep-wake cycles and daily activities. Previous studies have suggested that this individual difference can influence our biological and psychological functioning. Literature regarding the psychometric properties and validity of CT measures are reviewed. We provide an overview of biological indicators (sleep-wake cycle, body temperature, cortisol, and melatonin) that are used for distinguishing two chronotypes: morningness (MT) and eveningness (ET). We also review the differences between CT in relation to personality traits and the occurrence of psychopathology. In addition, the methodological limitations of studies on CT are discussed. Finally, future research directions in terms of CT are proposed.

Objectives : Few studies have examined the relation between the attachment styles of the primary caregivers and the behavioral problems of their children. This study was performed to identify the impact of the insecure parental attachment patterns on the development of their higher grades elementary school children's psychiatric manifestations and disorders. Methods : 504 higher elementary pupils and their primary caretakers were included in our study. Relationship Questionnaire, Kovacs Children's Depression Inventory, Spielberger's State-Trait Anxiety Inventory for children, and Korean Child Behavior Checklist were applied to them. Results : The grade-school children of the parents who belonged to preoccupied attachment type revealed higher Withdrawn, Anxious/depressed, Social Problems, Attention Problems, Delinquent Problems, Aggressive Problems, Internalizing Problems, Externalizing Problems, Total Behavioral Problems scores than ones of securely attached parents (p<0.01). Internalizing Problems score of preoccupied parents' children was highest, and one of avoidant and secure typed parents' kids followed in order (p=0.004) . More youngsters revealed Total Behavior Problem score high enough to clinically meaningful level in insecure parental attachment style than in secure one (p=0.038). Higher CDI score in insecure parental group was reported than in secure one (p=0.040). Conclusion : Parental insecure attachment can be associated with the development of the behavioral problems and psychiatric illness of their children.

Objectives : Some studies have reported that chronotypes, among several factors, could contribute to problematic drinking. However, there is little evidence confirming this relationship between chronotype and problematic drinking based on gender differences in mood disorder. This study is to investigate the difference of the relationship between chronotype and problematic drinking according to gender differences in mood disorder. Methods : Two hundred fifteen patients with mood disorder were recruited. Problematic drinking and chronotypes were assessed by the Alcohol Use Disorder Identification Test in Korea(AUDIT) and the Korean translation of composite scale of morningness(KtCS). We analyzed the correlation between KtCS and AUDIT using Pearson's correlation, and compared AUDIT scores according to chronotypes classified by KtCS between male and female patients using analysis of variance(ANOVA). Results : There was no significant difference in AUDIT scores between the male and female patients(t=0.91, p=0.183). In female patients, eveningness had significantly higher AUDIT scores than other chronotypes(F=0.199, p=0.033). Meanwhile, in male patients, there was no significant difference in AUDIT score among chronotypes(F=0.008, p=0.933). Conclusion : This study suggests that eveningness might be associated with problematic drinking in female patients who suffer from mood disorder. It also suggests that chronotherapeutical treatment might be able to help improve the course in female patients with mood disorder. In the future, a large-scale prospective study is needed to confirm these results.

This study is attempted to examine Korean teachers’ perceptions of mental health problems in students and their attitudes towards psychiatric consultations through a questionnaire survey. The results of this study are as follows. 1) Teachers thought that 5.3% of their students had mental health problems, 1.9% of students required psychiatric evaluation, and 1.2% of students were referred or recommended psychiatric evaluation by their teachers. 2) The most frequent mental health problems in students discovered by teachers were distractibility and inattention, lack of academic skills, and language difficulties in elementary schools；distractibility and inattention, conduct problems, and lack of academic skills in middle schools；and conduct problems, distractibility and inattention, physical symptoms, and substance abuse in high schools. 3) Teachers thought the mental health problems in students were caused by the family environment, psychological factors, the educational system, and a lack of mental health services. 4) Teachers desired smaller classes, improvement of the school environment, more time, regular mental health education, a special program for students with mental health problems, and the counseling staffs or consultants for the school mental health. 5) Teachers consulted with other teachers, the parents of the students, the counseling teachers, the health care teachers, the counseling institutes, the psychiatric clinics, and the principals in descending order to handle the hard case problems. The frequent reasons for failing in psychiatric consultations were the prejudice of parents against psychiatric services, the teachers’ sense of superiority in dealing with the problems of students, the prejudice of teachers themselves against psychiatric practice, and inaccessible professional consultation. 6) About 20.4% of teachers reported they had proposed psychiatric consultations or had recommended their students to receive psychiatric evaluations.

The current study aimed to explore the suicidal behaviors and risk factors of completed suicides using psychological autopsy and use them as index variables to classify suicidal types. In addition, this study looked into the influential factors that affect each suicidal type. related to suicidal behaviors and suicidal risk factors by psychological autopsy. In addiction, the distinctions among the classes were analyzed. For this, psychological autopsies were conducted on the families and the close ones of 128 completed suicides. Then, the index variables were finally chosen for classifying suicidal types. The selected index variables for suicidal risk factors were mental disorders, suicide/self-harm, significant changes in physical appearance, marital conflict, adjustment and relationship issues at work/school, unemployment/layoff, jobless status and serious financial problems. The selected index variables for suicidal behaviors were expressing their suicidal attempts, writing suicidal notes, asking for help, the time/place/method of suicidal behavior, past suicidal/self-harm experience and the first person who witnessed the suicide. The Latent Class Analysis(LCA) and the 3-step method were used for classifying suicidal types. Then external variables(financial changes, cohabitation, existence of stressors, changes in stress level or relationships and family members with mental disorder/alchohol problems/ physical disorders, and work/school stisfaction) were applied for distinguishing classes. As a result, 5 classes(financial problems, adjustment problems, complex problems, psychiatric problems, and response to event[s]) were revealed on suicidal behaviors and 3 classes(residence- suicidal attempt- found by family, nonresidence- nonsuicidal attempt- found by acquaintances, residence- nonsuicidal attempt- found by family) were presented on suicidal risk factors. External variables such as gender, marital status, cohabitation, changes in relationships significantly differentiated among the 3 classes. Especially, class 3(residence- nonsuicidal attempt- found by family) tended to cohabit with others, were married, and had a significantly high level of interpersonal conflicts. When comparing the 5 classes of suicidal risk factors, auxiliary variables such as economic changes, cohabitation, stress, relationship changes, and family-related problems, and school/work satisfaction significantly differentiated the 5 classes. Especially class 3 (complex problems) experienced comparatively less family-related problems, but showed an aggravating level of personal stress. Suicial prevention strategies should be provided considering the characteristics of each class and the influential factors.
