Purpose: This study analyzed the increase in disposal rate of femoral heads in the bone bank of a single hospital from medical disease and drug history, as assessed by the Korean health insurance review and assessment service. Materials and Methods: The disposal rate and cause of 340 femoral heads were analyzed according to the regulations of the bone bank based on the standard model of the Ministry of food and drug safety. Results: One hundred and seven (33%) of 323 femoral heads collected from 2009 to 2018, and 65 (46%) of 142 femoral heads collected from 2015 to 2018 were discarded. The most common causes were related to the history of dementia and the administration of radioisotope for nuclear medicine. Conclusion The current methods and screening tools can lead to errors in disposing of the available tissues in a bone bank. Thus, improved standards and screening methods are needed.

Purpose: The purpose of this study was to understand the parenting stress and health promotion behavior of working women, and to investigate the mediating effect of supporting resources. Supporting resources were set as social support of spouse and community, and institutional support of the organization to which the subject belongs based on previous studies and an ecological system theory. Methods: The participants were composed of 214 female workers residing in 17 cities and provinces nationwide and having at least one child aged 1~12 years old. Data were collected online from February 19 to February 28, 2021. The collected data were analyzed using the SPSS 20.0 program to understand the level and correlation of the general characteristics and major variables, and to test the mediating effect, after controlling the variables significantly from univariate analysis, step regression analysis was performed. Results: Among the supporting resources, the mediating effect of social support of spouse and community was statistically significant. Conclusion These findings suggest that it is necessary to seek ways to increase the social support of working women's spouses and people around them in order to increase the health promotion behavior of working women.

OBJECTIVE: The suicide rate in South Korea was the second highest among the Organization for Economic Cooperation and Development countries in 2017. The purpose of this study is to understand the characteristics of people who died by suicide in Korea from 2013–2017 and to better prevent suicide. METHODS: This study was performed by the Korea Psychological Autopsy Center (KPAC), an affiliate of the Korea Ministry of Health and Welfare. According to the Korea National Statistical Office, the number of suicide victims nationwide was estimated to reach about 70,000 from 2013 to 2017. Comprehensive suicide records from all 254 police stations in South Korea were evaluated by 32 investigators who completed a 14-day didactic training program. Then, we evaluated the characteristics of suicide victims in association with disease data from the National Health Insurance Database (NHID), which is anonymously linked to personal information of suicide victims. RESULTS: Thirty-one of 254 police stations in the Seoul metropolitan area were analyzed by August 10, 2018. Findings showed that the characteristics of suicide victims differed according to the nature of the region. CONCLUSION: Our results suggest that different strategies and methods are needed to prevent suicide by regional groups.

PURPOSE: The purpose of this study was to examine the differences in requirement and activity related to workers' health promotion according to business type and enterprise size. METHODS: This study is a secondary analysis of data extracted from a survey on the Enterprise Health Promotion Index. For the present analysis, 7,784 companies were selected. RESULTS: Requirements for lifestyle management and activities to prevent musculoskeletal disorders were the highest. The requirement and activity of musculoskeletal disorders and cerebrovascular disease were high in the manufacturing industry. Meanwhile, in the non-manufacturing industry, the requirement and activity of job stress management were high. Small-sized companies had a high requirement to prevent musculoskeletal disorders and cerebrovascular disease. CONCLUSION Government support should be strengthened in workers' lifestyle management. Additionally, workers' health promotion in small-sized companies needs to focus on preventing musculoskeletal disorders and cerebrovascular disease.

Gender differences in aggression viewed from an evolutionary and sociocultural perspective have traditionally explained why men engage in more direct and physical aggression, and women engage in more indirect and relational aggression. However, psychological and behavioral studies offer inconsistent support for this theory due to personal or social factors, and little is known about the gender-based neurobiological mechanisms of aggression. This study investigates gender differences in aggression through an analysis of electroencephalography (EEG) and electrocardiography (ECG) based neurobiological responses to commonly encountered stimuli, as well as psychological approaches in healthy Korean youth. Our results from self-reports indicate that overall aggression indices, including physical and reactive/overt aggression, were stronger in men. This agrees with the results of previous studies. Furthermore, our study reveals prominent gender-related patterns in γ signals from the right ventrolateral frontal cortex and changes in heart rate through stimulation by aggressive videos. In particular, gender differences in EEG and ECG responses were observed in response to different scenes, as simple aversion and situation-dependent aggression, respectively. In addition, we discovered decisive gender-distinct EEG signals during stimulation of the situation-dependent aggression regions within the right ventromedial prefrontal and ventrolateral frontal regions. Our findings provide evidence of a psychological propensity for aggression and neurobiological mechanisms of oscillation underlying gender differences in aggression. Further studies of oscillatory responses to aggression and provocation will expand the objective understanding of the different emotional worlds between men and women.

PURPOSE: This study was conducted to evaluate the validity of the ‘ Enterprise Health Promotion Index’, a tool for assessing health promotion activities of worksite developed by the Ministry of Employment and Labor and the Korea Occupational Safety and Health Agency. METHODS: This is designed a methodological study that evaluates the validity of the Enterprise Health Promotion Index. For this study, a questionnaire survey was conducted for the workplace health professional and safety professional, and a total of 297 data were extracted as final data. We developed the informal health promotion needs and activity measurement tools. The correlation coefficient between the score of the enterprise health promotion index and the score of the informal health promotion tool was analyzed for the criterion validity evaluation. RESULTS: The criterion validity of the Enterprise Health Promotion Index and activity index were supported by finding moderate (r=.597) and high (r=.783) correlation coefficient. However, the requirement index has low levels of criterion validity (r=.364). CONCLUSION: Based on these results, we suggest to improve the utility of the corporate health promotion index by developing user manual, active public relations, and providing briefing sessions.

This study aimed at constructing a draft genome of the adult female worm Toxocara canis using next-generation sequencing (NGS) and de novo assembly, as well as to find new genes after annotation using functional genomics tools. Using an NGS machine, we produced DNA read data of T. canis. The de novo assembly of the read data was performed using SOAPdenovo. RNA read data were assembled using Trinity. Structural annotation, homology search, functional annotation, classification of protein domains, and KEGG pathway analysis were carried out. Besides them, recently developed tools such as MAKER, PASA, Evidence Modeler, and Blast2GO were used. The scaffold DNA was obtained, the N50 was 108,950 bp, and the overall length was 341,776,187 bp. The N50 of the transcriptome was 940 bp, and its length was 53,046,952 bp. The GC content of the entire genome was 39.3%. The total number of genes was 20,178, and the total number of protein sequences was 22,358. Of the 22,358 protein sequences, 4,992 were newly observed in T. canis. Following proteins previously unknown were found: E3 ubiquitin-protein ligase cbl-b and antigen T-cell receptor, zeta chain for T-cell and B-cell regulation; endoprotease bli-4 for cuticle metabolism; mucin 12Ea and polymorphic mucin variant C6/1/40r2.1 for mucin production; tropomodulin-family protein and ryanodine receptor calcium release channels for muscle movement. We were able to find new hypothetical polypeptides sequences unique to T. canis, and the findings of this study are capable of serving as a basis for extending our biological understanding of T. canis.

Caudal pulmonary artery diameter (CPAD) to body surface area (BSA) ratios were measured in ventrodorsal thoracic radiographs to assess the correlation between CPAD to BSA ratios and systolic pulmonary arterial pressure (PAP) in dogs. Thoracic radiographs of 44 dogs with systolic pulmonary arterial hypertension (PAH) and 55 normal dogs were evaluated. Systolic PAP was estimated by Doppler echocardiography. CPADs were measured at their largest point at the level of tracheal bifurcation on ventrodorsal radiographs. Both right and left CPAD to BSA ratios were significantly higher in the PAH group than in the normal group (p < 0.0001). Linear regression analysis showed positive associations between PAP and right and left CPAD to BSA ratio (right, p = 0.0230; left, p = 0.0012). The receiver operating characteristic curve analysis revealed that the CPAD to BSA ratio had moderate diagnostic accuracy for detecting PAH. The operating point, sensitivity, specificity, and area under the curve were 28.35, 81.40%, 81.82%, and 0.870; respectively, for the right side and 26.92, 80.00%, 66.67%, and 0.822, respectively, for the left. The significant correlation of CPAD to BSA ratio with echocardiography-estimated systolic PAP supports its use in identifying PAH on survey thoracic radiographs in dogs.
