Objective-Experiencing traumatic events in childhood is related to various psychiatric problems in adulthood, and a comprehensive tool for measuring childhood trauma is necessary in this field. This study aimed to examine the psychometric properties, and factor structure of the Korean version of the Early Trauma Inventory Self Report-Short Form (ETISR-SF). ETISR-SF measures the childhood trauma, including physical, and emotional sexual abuse, as well as general traumas. Methods-A clinical and nonclinical samples comprising of 97 subjects from a local community, and 207 patients with the ETISR-SF, were assessed. Other tools, including the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI) were used to assess clinical symptoms. Additional data from 69 college students was used to examine the test-retest reliability. Results-The original four-factor model was supported by the confirmatory factor analysis scale [χ2 (351, n=304)=3374.025, p<0.001, TLI=0.969, CFI=0.972, RMSEA=0.030]. The ETISR-SF was found to be a reliable instrument (Cronbach’s α=0.869). Comparison of the ETISR-SF scores discriminated the clinical group from that of the control group. The measure showed good convergent and divergent validity, in that the scores were correlated higher with the scores on the CTQ-SF (0.691) than with the scores on the BDI or BAI (0.424, 0.397 respectively). The ETISR-SF was found to be temporally stable, showing the moderate to high correlation (0.844). Conclusion-These findings suggest that the Korean version of the ETISR-SF appears to be a reliable and valid instrument for the measurement of reported childhood trauma.

The goal of the study was to examine the prevalence and psychiatric comorbidities of Internet addiction in a nationwide sample of Korean adults. Among a total of 6,022 participants involved in Korean Epidemiological Catchment Area study in 2011, 3,723 Internet users were assessed for their Internet addiction using Young’s 8-item Diagnostic Questionnaire. The results showed that of the 3,723 Internet users, 39 (1.0%) had Internet addiction. Addicted Internet users were younger, more likely to be males and unemployed compared to non-addicted Internet users. Internet addiction was associated with alcohol and nicotine use disorders, depressive disorders, and anxiety disorder after controlling for age, gender, and occupational status. Internet addiction was associated with suicidal plans even after controlling for psychiatric disorders and socio-demographic factors. This study showed that Internet addiction is highly associated with variety of different psychiatric disorders and suicidal plans. Therefore, clinicians should carefully evaluate them when treating addicted Internet users.

Objective The purpose of the present study was to investigate the association between Body Mass Index, suicide, perceived stress, and life dissatisfaction in a general population sample of Korean adults. Methods A total of 6,022 nationally representative adults aged 18 to 74 were selected using a multistage cross-sectional cluster sampling method. Questionnaires regarding suicide behaviors, perceived stress, and life satisfaction were completed by the participants. They also reported their heights and weights, which were used to calculate BMI. Psychiatric disorders were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, using the Korean version of the Composite International Diagnostic Interview. Results The results showed that being underweight was associated with higher risk for suicide ideation [odds ratio (OR), 1.6; 95% confidence interval (Cl), 1.18-2.05] and suicide attempt (OR, 2.0, 95% Cl, 1.23-3.31). Likewise, obesity also increased the risk of suicide ideation (OR, 1.3; 95% Cl, 1.11-1.56) although not suicide attempt. Furthermore, underweight individuals were more likely to report severe level of perceived stress (OR, 1.7; 95% Cl, 1.26-2.17) and life dissatisfaction (OR, 1.3; 95% Cl, 1.07-1.68). All of the results remained significant after adjusting for age, gender, education, and psychiatric illnesses. Conclusion This study found that being underweight is a significant risk factor for suicide and poor subjective wellbeing in Korea. It suggests that BMI status may be an important modifiable factor for improving mental health in Korea.

Frontal Lobe Dysfunction in a Depressed Patient Who Survived a Suicide Attempt by Jumping from the Bridge on the Han River

Kiwon Kim,HongJin Jeon 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.6

Suicide attempts at the Han river are rapidly increasing, which are 4.11 times from 2005 to 2015, whereas the rate of completed suicide in South Korea increased 1.07 times during the same period. However, few studies have been conducted on the issue because many suicide attempters were seriously injured after a fall in the Han river. We present a case of a patient with major depressive disorder (MDD) who attempted suicide and minimally injured after jumping from the bridge at the Han river. We could assess his psychological and neurocognitive functions before and immediately after his attempt. From this case, we can identify that higher cognitive aspect of executive dysfunction, especially in the frontal domain of selective attention and inhibition, may be associated with his suicide attempt. In conclusion, we suggest psychiatric treatments for cognitive impulsiveness and safety barriers at the bridge to prevent suicide attempts of patients with MDD.

Childhood Exposure to Psychological Trauma and the Risk of Suicide Attempts: The Modulating Effect of Psychiatric Disorders

Subin Park,JinPyo Hong,HongJin Jeon,Sujeong Seong,MaengJe Cho 대한신경정신의학회 2015 PSYCHIATRY INVESTIGATION Vol.12 No.2

Objective-We examined whether childhood exposure to psychological trauma is associated with greater suicidality and whether specific psychiatric disorders modulate this association in a representative sample of Korean adults. Methods-The Korean version of the Composite International Diagnostic Interview 2.1 was administered to 6,027 subjects aged 18–74 years. Subjects who experienced a traumatic event before the age of 18 years, the childhood-trauma-exposure group, were compared with controls without childhood trauma exposure. Results-Childhood exposure to psychological trauma was associated with lifetime suicidal ideation (OR=3.19, 95% CI=2.42–4.20), suicide plans (OR=4.15, 95% CI=2.68–6.43), and suicide attempts (OR=4.52, 95% CI=2.97–6.88). These associations weakened after further adjustment for any psychiatric disorders, but they were not eliminated. The risk of suicide attempts related to childhood trauma increased with the presence of a concurrent alcohol use, depressive, or eating disorder. Conclusion-In terms of clinical implications, patients with these disorders who have a history of childhood trauma should be carefully assessed for their suicide risk and aggressively treated for psychiatric disorders.

Ji-Eun Hwang,Su-Gyeong Jeon,Kil-Su Jang,Oh-Hun Kwon,Tae-Young Kwon,Hongjin Long,Min Gui,Qiuyue Zhong,Lei Du 한국육종학회 2013 한국육종학회 심포지엄 Vol.2013 No.07

Fruit quality traits like heat, color and flavor are unique and important for pepper cuisines and industrial use. Pepper pigments include chlorophyll, carotenoids, anthocyanin and red pigments like capsanthin are unique carotenoids to capsicum spp. So developing carotenoids-rich peppers and use of red pigments extraction along with capsaicinoids are one of interest pepper breeding goals in the world. Horticultural traits of 113 germplasms introduced by international cooperative research with YASS of China were evaluated to select promissing materials for high quality peppers during the past 3 years. All of germplasms including 60 local peppers were belong to C. annuum and fruit characteristics were diverse. Especially fruit chemical compositions like ASTA color, capsaicinoids and sugars were evaluated compared with korean commercial peppers. Average contents of ASTA color was 98±37, 55±63mg in capsaicinoids and 12±6% in total sugars. ASTA color which generally means red pigments content was over 120 in 25 germplasms including over 200 in 2 germplasms. Higher ASTA colors were observed in different fruit types. Capsaicinoids content was over 90mg/100g in 24 germplasms including 5 germpalsms over 200mg. Especially higher capsaicinoids were higher in local peppers with round and wrinkled fruit shape. And total sugar content was over 20% in 10 germplasms. Germplasms of different fruit shapes and characteristics will be useful materials for diverse fruit quality breeding.

Although in the U.S perchloroethylene is the most commonly used in commercial dry cleaning shops, petroleum based dry cleaning solvent is the most frequently used in Korea. The solvent is a mixture of hydrocarbons, straight or branched chain aprraffins, naphthenes, and aromatic hydrocarbons. Exposure assessment at the cleaning shop was mainly focused on highly toxic substances, especially benzene, toluene, xylene, ethylbenzene, and 2-butoxyethanol in the solvents. However the contents of the toxic substances in the solvents are very small. Not only the exposure assessment for highly toxic substances is important, but also exposure for the petroleum based solvent itself is more important in dry cleaning shop. The specific aim of the present study was to identify the physical and the chemical properties of petroleum based dry cleaning solvents and to investigate the possivility of using occupational exposure standard of stoddard solvent for overall expostreassessment of petroleum based solvent. Four different petroleum based solvent(solvent A~solvent D). commonly used in Korda were analyzed and investigated for identifying the phtsical and chemical properties of those solvents. Molecula species of those solvents were C8~C12, and predominant molecular species were C10~C11 for solvent A, solvent C, solvent D. C9~C10 for solvent B. The proportion of paraffin, aromatic, naphthenic,and olefin compounds in dry cleaning solvents was 45.5~54.5%, 16.0~21.4%, 7.9%~15.8%, and 0.8%~1.0%, respectively. The range of boiling point, specific grabity, flash point found in material safety and data sheet made by the solvent manufacturing company was 150 ~210˚C. 0.76~0.79, and 30~44˚C., respectively. We conclude that petroleum based solvents used in dry cleaning shop is almost similar to stoddard solvent defined by ACGIH and NIOSH, and the occupational exposure standard of stoddrd solvent could be used in total exposure assessment of those solvents.

Agoraphobia and Follicle-Stimulating Hormone Levels between Tamoxifen and Goserelin versus Tamoxifen Alone in Premenopausal Hormone Receptor-Positive Breast Cancer: A 12-Month Prospective Randomized Study

JungYoon Heo,Hawoo Yi,Maurizio Fava,David Mischoulon,Kiwon Kim,Sechang Yoon,HongJin Jeon,JeongEon Lee 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.4

Objective-Tamoxifen is an estrogen receptor antagonist used to prevent recurrence of breast cancer, which may provoke depression and anxiety and increase follicle-stimulating hormone (FSH) to patients. We compared anxiety and depression symptoms and FSH levels who received conventional tamoxifen alone and combination treatment of goserelin, a gonadotropin-releasing hormone (GnRH) analogue, with tamoxifen. Methods-Sixty-four premenopausal women with hormone receptor-positive early-stage breast cancer were included and were assigned randomly to receive either tamoxifen and goserelin combination or tamoxifen alone for 12 months. The participants were evaluated blindly using the Hamilton Depression and Anxiety Rating Scale, the Beck Depression Rating Scale, and the Albany Panic and Phobia Questionnaire (APPQ). Blood FSH levels were assessed at baseline, 6 and 12 months. Results-A significant time×group difference was detected in the agoraphobia trends subscale of the APPQ and in FSH levels. The combination group showed significantly less increases in agoraphobia subscale of APPQ and greater decreases in FSH level than those in the tamoxifen-alone group from baseline to 12 months of treatment. No significant differences for age, tumor grade, body mass index, or family history were found at baseline between the two groups. Conclusion-Our results suggest that the combination treatment of tamoxifen and goserelin resulted in less agoraphobia than tamoxifen alone in premenopausal women with breast cancer, which may associated with FSH suppression of goserelin.
