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.

The purpose of this study was to investigate the mediating pathways of emotional regulators in relation to self-conscious negative emotions, including non-suicidal self-harm, guilt, shame, shyness, and internal hostility, further examining the gender difference in the mechanisms. The study subjects of were 652 college students from three universities in J district. Self-report questionnaires on self-harm, self-conscious negative emotions, and emotional control were administered to them. An analysis performed using model 4 of the process macro indicated that self-conscious negative emotions had a significant correlation with self-harming behavior and that this correlation was mediated by the emotional regulation of brooding. These results suggest that negative self-conscious emotions have a significant influence on self-harming behaviors, and brooding reinforces negative emotions then the risk of self-harming behaviors is amplified.

Recently due to increase of tobacco users, many problems have been issued. Not only smoking in public places, smoking indoors as well causes harm to non-smoking people. Smoking booths that are installed but the quality is considerably less and purification devices are not correctly installed, which leads to harm the people around the smoking booth. In this paper, we introduce the "Augmented Reality Billboard" in order for smokers to effectively recognize the non-smoking warning image and healthy warning messages, Kinect Camera Sensor and Augmented Reality (AR) functions are used to recognize the motion of a person to coordinate the corresponding coordinate values.

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.

In this paper, we quantitatively analyzed the required UAV(Unmanned Aerial Vehicle) failure rate of small UAV (≤25kg) based on the harm to human caused by UAV crash to fly over the populated area. We compute the number of harm to human when UAV falls to the ground at certain descent point by using population density, car traffic, building to land ratio, number of floors of building data of urban area and UAV descent trajectory modeling. Based on this, the maximum allowable UAV failure rate is calculated to satisfy the Target Level of Safety(TLS) for each UAV descent point. Then we can generate the failure rate requirement in the form of map. Finally, we divide UAV failure rate into few categories and analyze the possible flight area for each failure rate categories. Considering the Youngwol area, it is analyzed that the UAV failure rate of at least 10^-4 (failure/flight hour) is required to access the residential area.

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.

A radiographer is a job in charge of diagnostic imaging equipment, and must contribute to the promotion of public health by suggesting an appropriate level of work. To this end, we intend to present an appropriate level of work through evaluation of human harm according to work, statistical evaluation through questionnaires, and domestic and international trends. In the case of human harm evaluation, considering radiation exposure, 42.6%, shield work, 69.7%, and in the case of magnetic resonance imaging, the maximum length of stay in the examination room should be adjusted to 15 minutes and not exceed 30 times. According to the survey statistics, it was confirmed that the physical and mental burden increased due to the high workload and difficulty compared to working hours. Based on domestic and international trends, it is necessary to adjust the examination standards for domestic radiographers to 36.8% to promote national health through qualitative improvement of radiological examinations. something to do.

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.
