Objectives : The Center for Epidemiologic Studies Depression scale-Revised is a recently revised scale which has been reported as a valid tool for the assessment of depressive symptoms. It encompasses cardinal symptoms of depression described in the Diagnostic and Statistical Manual of Mental disorders, fourth edition. In this study, we assessed the reliability, validity and psychometric properties of the Korean version of the CESD-R(K-CESD-R). Methods : Forty-eight patients diagnosed as major depressive disorder, dysthymia, depressive disorder NOS according to the DSM-IV criteria using Mini International Neuropsychiatric Interview and 48 healthy controls were enrolled in this study. They were assessed with K-CESD-R, K-MADRS, PHQ-9, KQIDS-SR, STAI to check cross-validation. Statistical analyses were performed using calculation of Cronbach's alpha, Pearson correlation coefficient, Principal Component Analysis, ROC curve and optimal cut-off value. Results : The Cronbach's alpha of K-CESD-R was 0.98. The total score of K-CESD-R revealed significantly high correlations with those of K-MADRS, PHQ-9, KQIDS-SR(r=0.910, 0.966 and 0.920, p<0.001, respectively). Factor analysis showed two factors account for 76.29% of total variance. We suggested the optimal cut-off value of K-CESD-R as 13 according to analysis of the ROC curve which value sensitivity and specificity both equally. Conclusions : These Results showed that the K-CESD-R could be a reliable and valid scale to assess depressive symptoms. The K-CESD-R is expected as a useful and effective tool for screening and measuring depressive symptoms not only in outpatient clinic but also epidemiologic studies.

In this paper, wave responses of buoyant flap-typed storm surge barriers was studied numerically. Wave motions were modeled by using a linear potential wave theory, and behaviors of structures were represented as a Newton's 2nd law of motion. The near field region of the fluid was discretized as conventional quadratic iso-parametric elements, while the far field was modeled as infinite elements. Comparisons with the results from hydraulic model tests show that the present model gives good results. By using the model, the applicability of a buoyant flap-typed storm surge barrier in Masan bay was investigated considering field environmental conditions.

Objectives : Homocysteine has been associated with cognitive impairment and various psychiatric symptoms. This study was designed to examine the relationship exists between plasma homocysteine concentration and behavioral and psychological symptoms of dementia(BPSD). Methods : 41 subjects with dementia of Alzheimer's type were included in this study. We carried out history taking, physical examination, and cognitive assessment for the diagnosis of dementia of Alzheimer's type based on DSM-IV. We scored the Mini Mental State Examination(MMSE), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), and the Korean Neuropsychiatric Inventory(K-NPI). We also measured levels of homocysteine, folate, and vitamin $B_{12}$ in the plasma. Results : We found statistically significant positive correlations between homocysteine concentration with NPI total score, and with scores of several sub-domains such as delusion, agitation/aggression, depression/dysphoria, and elation/euphoria. No significant correlation existed between homocysteine levels and scores of MMSE, GDS, and CDR. Conclusions : This study shows that plasma homocysteine levels are associated with BPSD. Further research is necessary to identify pathophysiologic mechanisms underlying these relationships.

Objective : This study was designed to evaluate the incidence and characteristics of posttraumatic stress disorder(PTSD) after motor vehicle accidents(MVA) in 44 consecutive MVA victims referred to psychiatry for the diagnosis, treatment and psychiatric assessment. Method : The diagnosis of posttraumatic stress disorder was made on the basis of DSM-IV criteria, and posttraumatic stress symptoms were assessed by the Clinician-Administered PTSD Scale(CAPS). Correlation between the extent of physical injury and the severity of PTSD symptoms using the Abbreviated Injury Scale(AIS) was analyzed and the frequency of psychiatric comorbidity of PTSD was invested. Result : Twenty-two(45.5%) MVA victims met DSM-IV criteria for PTSD, while thirteen(29.5%) showed a subsyndromal form of it. AIS scores significantly related with the development of posttraumatic stress symptoms(r=0.565, p=0.0001). PTSD group showed high percentages of each of the 17 symptoms(criterion B, C, D), while subsyndromal PTSD group showed relatively high percentages of criterion Band D. The most frequent symptom was 'distressing dreams' of criterion B in both group. A high percentages(56%) of the MVA-PTSD group also met the criteria for current major depression. Conclusions : These findings suggest that there is apparently a high likelihood of developing all or part of the PTSD syndrome after motor vehicle accidents. So it does appear that for those MVA victims who seek medical attention and eventually need psychiatric referral, diagnostic possibility of PTSD should be taken into account in treatment planning and early intervention.

Objects：This study was carried out to develop the Korean form of Moral Development Inventory for Adolescents designed to assess the principled morality in adolescents. And the auther also intended to find the demographic variables that influence the moral development. Methods：The Korean form inventory was applied to 507 middle and high school adolescents, and retest was done in 42 second year middle school adolescents with 3 weeks interval. Together this inventory, short form of Rest moral development which had been proved its reliability and validity, were administered to the all subjects for concurrent validity. And then the author examined whether this inventory discriminates between conduct disorder patients, psychiatric controls and normal controls in the level of moral development. Results：Test-retest reliability and internal consistency were very satisfactory. Concurrent validity with this inventory was also high level. And conduct disorder patients were scored significant lower than psychiatric and normal controls in the level of principled morality. The mean PM scores did not show significant difference according to the variables such as sex, birth order and religion. But there was significant difference according to the educational level of mother and places. Conclusions：These results indicate that the Korean form of Moral Development Inventory is a reliable and valid rating inventory to assess the moral development level in Korean adolescents.

Purpose: This study was conducted to analyze the association between spirituality and stress of mental health social workers, which could be used in development of a program to help them manage stress and offer spiritual support. Methods: Participants were 154 mental health social workers in Korea. Data were collected from November 1 through November 30, 2011. The study employed the Korean version of the Spirituality Scale and Psychosocial Well-being Index-Short Form (PWI-SF). Data were analyzed using SPSS/Windows 17.0. Results: The mean score for the Spirituality Scale was 3.63 and for PWI-SF 18.78. Spirituality scores showed a significant difference among participants by age, education, religion and marital status. Psychosocial stress scores also significantly differed by marital status. Spirituality scores were negatively correlated with psychosocial stress scores (r=-0.548, P<0.001). Conclusion: In this study, a significant negative association was found between spirituality and stress in mental health social workers in Korea. A follow-up study with a larger sample of participants is needed to confirm these findings.

Objectives: The objective of this study was to confirm the Chiljeong (七情) characteristics of Hwa-byung patients using the core seven-emotions inventory-short form. Methods: We conducted a retrospective observational study based on the electronic medical records from a Korean medicine hospital. We included patients who were diagnosed with Hwa-byung and examined with Core Seven-Emotions Inventory-short Form (CSEI-S) during hospitalization periods. We presented the characteristics of Hwa-byung by demographic information, CSEI-S, Hwa-byung scale, and Korean Symptom Checklist 95. A correlation analysis was performed between CSEI-S and other clinical and psychological characteristics. Results: The Chiljeong characteristics of Hwa-byung were high in the order of Sorrow (悲), Thought (思), Fear (恐), Fright (驚), Depression (憂), Joy (喜), and Anger (怒). There was no significant difference between each emotion. After combined Korean medical treatment, Sorrow (悲) and Thought (思) significantly decreased. There were static correlations between sorrow (悲) and fright (驚), thought (思) and sorrow (悲), depression (憂) and sorrow (悲), depression (憂) and fright (驚), thought (思) and depression (憂), fear (恐) and fright (驚), anger (怒) and thought (思), thought (思) and fright (驚), sorrow (悲) and fear (恐). Sorrow (悲) and Hwa-byung characteristics scale showed static correlation. Joy (喜) showed a static correlation with disharmony between the heart and kidney scores of the Hwa-byung pattern identification. Between KSCL-95 and CSEI-S, static correlation appeared in depression (憂) with depression, anxiety, and sleep problem scale, sorrow (悲) with depression and anxiety, fright (驚) with depression and obsessive symptoms. Conclusions: Despite several limitations due to the study design and small sample size, this research successfully used CSEI-S to study the Chiljeong (七情) characteristics of Hwa-byung for the first time.

Objectives : Genome-wide association studies (GWASs) and meta-analyses indicate that single-nucleotide polymorphisms (SNPs) in the a-1C subunit of the L-type voltage-dependent calcium channel (CACNA1C) gene increase the risk for schizophrenia and bipolar disorders (BDs). We investigated the association between the genetic variants on CACNA1C and schizophrenia and/or BDs in the Korean population. Methods : A total of 582 patients with schizophrenia, 336 patients with BDs consisting of 179 bipolar I disorder (BD-I) and 157 bipolar II disorder (BD-II), and 502 healthy controls were recruited. Based on previous results from other populations, three SNPs (rs10848635, rs1006737, and rs4765905) were selected and genotype-wise association was evaluated using logistic regression analysis under additive, dominant and recessive genetic models. Results : rs10848635 showed a significant association with schizophrenia (p=0.010), the combined schizophrenia and BD group (p=0.018), and the combined schizophrenia and BD-I group (p=0.011). The best fit model was dominant model for all of these phenotypes. The association remained significant after correction for multiple testing in schizophrenia and the combined schizophrenia and BD-I group. Conclusion : We identified a possible role of CACNA1C in the common susceptibility of schizophrenia and BD-I. However no association trend was observed for BD-II. Further efforts are needed to identify a specific phenotype associated with this gene crossing the current diagnostic categories.
