Objectives The purpose of this study was to validate the biopsychological structure of Sasang Personality Questionnaire (SPQ) measuring Yin-Yang temperament with Junior version of Temperament and Character Inventory (JTCI) for temperament and Body Mass Index (BMI) and Pondera Index (PI) for physical constitution in elementary school students. Methods 903 Korean elementary school students (430 boys and 473 girls) completed SPQ, JTCI, and height and weight measures. Then they were analyzed by their genders and age groups. The correlation between SPQ and JTCI subscales were examined. The differences found in the SPQ and JTCI subscales, BMI and PI among high (30%), middle (40%), and low (30%) SPQ groups were investigated by analysis of variance. The profile analysis was also performed to compare JTCI subscale profiles of three SPQ total score groups. Results The SPQ score was significantly (p<0.001), and positively correlated with the JTCI Novelty-Seeking and negatively with the JTCI Harm-Avoidance. The JTCI Novelty-Seeking score of high SPQ group was significantly (p<0.001) higher than that of low SPQ group, and the JTCI Harm-Avoidance score of low SPQ group was significantly higher than that of high SPQ group. The JTCI subscale profiles for three SPQ groups were significantly (p<0.001) different for boys and girls. Significant correlations between BMI and SPQ were not found. PI and BMI of high and low SPQ groups were not significantly different. Conclusions The SPQ was shown to have robust biopsychological structure in elementary school students. It would be useful clinical measures for Sasang typology in pediatric patients.

Objective : High-risk pregnant women are exposed to the physical and emotional crisis associate with the condition of high-risk pregnancy, making these women emotionally unstable, exhibiting such conditions as depression and anxiety. The aim of this study was to examine what effects the temperament and character of high-risk pregnant women had on their depression, anxiety, and maternal-fetal attachment. Methods : A hundred and five high-risk pregnant women were recruited in the maternity ward of the Keimyung University medical center. All subjects were administered a sociodemographic and obstetric questionnaire, Temperament and Character Inventory, Beck Depression Inventory-II, State Trait Anxiety Inventory-State, and Maternal-Fetal Attachment Scale. Results : First, higher scores on the harm-avoidance scale and lower scores on the self-directedness scale were associated with higher depression scores. Second, higher scores on the harm-avoidance and reward-dependence scale were associated with higher anxiety scores. Lastly, higher scores on the cooperativeness scale were associated with higher maternal-fetal attachment scores. Conclusion : Temperament and character in high-risk pregnant women were associated with the degree of depression, anxiety, maternal-fetal attachment. Based on these findings, it is suggested that examining temperament and character in advance and screening for vulnerability in pregnant women can help to prevent emotional problems for high-risk pregnant women.

본 연구에서는 죄책감, 수치심, 수줍음, 내부 적대감을 포함하는 자의식적 부정정서와 비자살적 자해의 관계에서 정서조절기제의 매개효과를 규명하고자 하였다. 본 연구의 대상은 J지역 3개 대학교에 재학 중인 대학생 652명으로, 이들에게 비자살적 자해, 자의식적 부정정서, 정서조절에 대한 자기보고식 설문지를 실시하였다. Process macro의 model 4를 사용한 매개분석 결과, 자의식적 부정정서는 자해행동과 유의한 관련성을 보였으며, 부정적 반추의 정서조절이 그 관련성을 매개하는 것으로 나타났다. 이러한 결과는 자의식적 부정정서가 높을수록 비자살적 자해 행동이 증가하며, 부정적 반추가 부정정서를 더욱 강화시켜 자해 행동을 증폭시킴을 확인할 수 있었다.

Suicide is a major public health issue that causes over 800,000 deaths each year globally. Korea ranks high in suicide rates, in which around 24.3 per 100,000 individuals are reported to have died by intentional self-harm in 2017 according to Statistics Korea. The aim of this study was to examine the current status and trend of suicide ideation and attempt using data from the following five sources: Korean National Health and Nutrition Examination (KNHANES, '07-13, '15-17), Korean Community Health Survey (KCHS, '08-09, '13, '17), Korean Wealth Panel Study (KOWEPS, '12-17), Korea Health Panel Survey (KHP, '10-13), and Statistics Korea (1983-2017). Suicide ideation and attempts were also further examined based on equalized household income levels. Data published by Statistics Korea were used to show the updated suicide rate and number of deaths by intentional self-harm. The rate of suicide ideation at the recent year was 4.73% (KNHANES, '17), 6.96% (KCHS, '17), 1.63% (KOWEPS, '17), and 5.39% (KHP, '13). That of suicide attempts as recent year was 0.71% (KNHANES, '17), 0.32% (KCHS, '17), and 0.09% (KOWEPS, '17). Annual percentage change of suicidal ideation was -15.4% (KNHANES, '07-17), -2.5% (KCHS, '08-17), -8.6% (KOWEPS, '12-17), and -10.9% (KHP, '10-13). Annual percentage change of suicide attempts was -4.0% (KNHANES, '07-17), -4.4% (KCHS, '08-17), and -14.9% (KOWEPS, '12-17). Individuals with lower income levels were more likely to experience suicide ideation and attempts. Considering that Korea still shows a high suicide rate despite the continuously decreasing trend of suicide ideation and attempt, continuous observation and appropriate policy implementation regarding suicide related problems are necessary.

Objectives: This study aimed to investigate the characteristics of early maladaptive schemas and their associations with clinical symptoms in patients with schizophrenia. Methods: Forty-eight patients with schizophrenia, 49 patients with major depressive disorder, and 50 healthy controls completed the Young Schema Questionnaire and symptom measures including the Brief Psychiatric Rating Scale-Expanded (BPRS-E). Results: The schizophrenia group had significantly higher scores than the healthy controls and lower scores than the depression group in most schemas. Compared with healthy controls, the schizophrenia group exhibited higher scores in 10 schemas, i.e., mistrust, social isolation, failure, dependence, vulnerability to harm, enmeshment, insufficient self-control, subjugation, emotional inhibition, and negativity schemas (all p<0.001). Moreover, vulnerability to harm, enmeshment, subjugation, and negativity schemas were correlated with total scores of the BPRS-E (0.37≤r≤0.43, all p<0.05). Regarding the five BPRS domains, emotional deprivation schema showed significant relationships with negative (r=0.50, p=0.005) and disorganization (r=0.39, p=0.033) symptoms, while no schemas showed correlations with positive symptoms. Conclusion: These results suggest that most schemas in patients with schizophrenia pertain to impaired autonomy and performance as well as disconnection and rejection domains and may improve our understanding and the treatment of schizophrenia from a perspective of schema therapy focused on these domains.

Background: With the increasing demand for industrial robots and the "noncontact" trend, it is an appropriate point in time to examine whether risk assessments conducted for robot operations are performed effectively to identify and eliminate the risks of injury or harm to operators. This study discusses why robot accidents resulting in harm to operators occur repetitively despite implementing control measures and proposes corrective actions for risk assessments. Methods: This study collected 369 operator-injured robot accidents in Korea over the last decade and reconstructed them into the mechanism of injury, work being undertaken, and bodily location of the injury. Then, through the techniques of Systematic Cause Analysis Technique (SCAT) and Root Cause Analysis (RCA), this study analyzed the root and direct causes of robot accidents that had occurred. Causes identified included physical hazards and complex combinations of hazards, such as psychological, organizational, and systematic errors. The requirements of risk assessments regarding robot operations were examined, and three case studies of robot-involved tasks were investigated. The three assessments presented were: camera module processing, electrical discharge machining, and a panel-flipping robot installation. Results: After conducting RCA and comparing the three assessments, it was found that two-thirds of injury-occurring from robot accidents, causative factors included psychological and personal traits of robot operators. However, there were no evaluations of the identifications of personal aspects in the three assessment cases. Conclusion: Therefore, it was concluded that personal factors of operators, which had been overlooked in risk assessments so far, need to be included in future risk assessments on robot operations.

Background: Injury is one of the major health problems in South Korea. Few studies have evaluated both intentional and unintentional injury when investigating the association between exposure to air pollutants and injury. Objectives: We aimed to explore the association between short-term exposure to ambient air pollution and years of life lost (YLLs) due to injury. Methods: Data on daily YLLs for 2002~2019 were obtained from the the Death Statistics Database of the Korean National Statistical Office. This study estimated short-term exposure to particulate matter with an aerodynamic diameter of <10 ㎛ (PM₁₀), particulate matter with an aerodynamic diameter of <2.5 ㎛ (PM_2.5), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and ozone (O₃). This time series study was conducted using a generalized additive model (GAM) assuming a Gaussian distribution. We also evaluated a delayed effect of ambient air pollution by constructing a lag structure up to seven days. The best-fitting lag was selected based on smallest generalized cross validation (GCV) value. To explore effect modification by intentionality of injury (i.e., intentional injury [self-harm, assault] and unintentional injury), we conducted stratified subgroup analyses. Additionally, we stratified unintentional injury by mechanism (traffic accident, fall, etc.). Results: During the study period, the average daily YLLs due to injury was 307.5 years. In the intentional injury, YLLs due to self-harm and assault showed positive association with air pollutants. In the unintentional injury, YLLs due to fall, electric current, fire and poisoning showed positive association with air pollutants, whereas YLLs due to traffic accident, mechanical force and drowning/submersion showed negative associations with air pollutants. Conclusions: Injury is recognized as preventable, and effective strategies to create a safe society are important. Therefore, we need to establish strategies to prevent injury and consider air pollutants in this regard.
