The Efficacy of Motivational Interviewing with Cognitive Behavioral Treatment on Behavior Changes in Heavy Drinkers

This study aimed to investigate the efficacy of motivational interviewing (MI) with cognitive behavioral treatment (CBT) on behavioral changes of heavy drinkers. This study used embedded mixed methods that integrate sequential qualitative interviews with quantitative evaluation. Of a total of 47 participants, 24 belonged to an intervention group, which participated in the MI with CBT on behavioral changes once a week, 25-30 min on average, for 8 weeks. A total of 23 participants were assigned to a control group, which received a 7-page booklet containing information about alcohol. A t-test, generalized linear model, and qualitative analysis were used to evaluate the effects of MI with CBT. The interview data (n = 13) were analyzed using qualitative content analysis. There was a statistically significant change in participants' beliefs concerning the immediate effects of drinking (F = 3.827, p = 0.025). Additionally, the intervention group had a significantly higher drinking refusal self-efficacy than the control group (F = 4.426, p = 0.015). Four themes emerged from the analysis of qualitative data: reduction of benefits of drinking, changes in thoughts about costs of drinking, changes in drinking behavior, and achieving self-efficacy. The MI with CBT significantly promoted awareness of problem-drinking behaviors among heavy drinkers and increased their self-efficacy, improving their ability to make positive behavioral changes for themselves. Since this intervention is simple and easy to apply, it will be useful for problem drinking-prevention strategies in the public health sector. Therefore, efforts to disseminate these strategies will be worthwhile from sustainable perspectives.Y

Factors Affecting the Deterioration of the Physical Health Status of Taxi Drivers by Age Group

With the rapidly aging population, taxi drivers are aging at a fast pace, and competition in the taxi industry is intensifying due to the emergence of various transportation platforms. A descriptive secondary data study was conducted (on a total of 936 subjects) to determine the factors affecting the deterioration of taxi drivers’ physical health status (PHS) according to their age group. The increased incidence of chronic diseases and cognitive decline among taxi drivers aged 55–64 years had the greatest influence on the deterioration of their PHS. Driver obesity was more likely to be related to deterioration of the PHS in the drivers aged 55–64 years (OR: 2.459, <0.001) and 35–54 years (OR: 2.133, <0.001). Among the financial factors, a driver’s income and their number of dependent family members were correlated with the deterioration of the PHS for drivers aged 55 years or over. Therefore, chronic diseases, obesity and cognitive decline were related with deterioration of the physical health status. This suggests that attention should be paid to healthcare policies not only for the elderly aged over 65 years but also those aged 50 to 64 years, i.e., middle-aged people at the beginning of the transition to old age

Subgroups of depressive symptoms in Korean police officers: A latent class analysis

The prevalence of depressive symptoms is common among police officers; however, studies that identify the patterns of depressive symptoms in police officers and occupational characteristics related to the specific subgroups of depressive symptoms are scarce. A total of 493 police officers in South Korea participated in this descriptive cross-sectional study between October and December 2019. Depressive symptoms were measured using the Patient Health Questionnaire-9. Latent class analysis was used to identify the subgroups of depressive symptoms. To identify the characteristics and predictors of the subgroup, χ2 tests, analysis of variance, and multinomial logistic regression analysis were performed. Four latent classes of depressive symptoms were identified: “at-risk” (10.8%), “anhedonic” (21.5%), “somatic” (17.2%), and “minimal” (50.5%). Compared to the minimal group, drinking behaviors were higher in the at-risk group (odds ratio [OR] = 1.10, 95% confidence interval [CI] [1.03, 1.11]), and working hours were greater in the somatic group (OR = 1.01, 95% CI [1.00, 1.02]). Additionally, sleep quality (OR = 1.35, 95% CI [0.82, 2.22]) and fatigue (OR = 1.02, 95% CI [1.00, 1.04]) were found to be related in the anhedonic group. This study identified the heterogeneity of depressive symptoms among police officers. It is necessary to accurately identify the factors associated with the depression subgroups of police officers to develop support strategies and prevent an increase in their depression severity. The association between risk factors such as working hours and drinking behaviors might inform strategies to reduce depression in police offers

Comparison of Physical, Occupational, and Sociocognitive Characteristics of Corporate and Private Taxi Drivers in Korea

Taxis are a form of public transport which is very closely related to the safety of the public. Although private and corporate taxis have quite different characteristics, there have only been a few studies comparing the characteristics of corporate and private taxis. Moreover, among various characteristics, research was conducted mainly focusing on occupational characteristics. This study was undertaken to compare various physical, occupational, and sociocognitive characteristics of corporate and private taxi drivers. A descriptive cross-sectional study was conducted from 22 August to 11 September 2018. The subjects of this study were 960 corporate and private taxi drivers over 30 years old in Seoul to compare the means and association between private and corporate taxi drivers’ characteristics. In terms of the physical characteristics, corporate taxi drivers’ general physical health status was worse. In terms of the occupational characteristics, corporate taxi drivers had a high working intensity, and the incidence rate of traffic accidents and near misses was also high. This comparison of the characteristics of corporate and private taxis is expected to serve as evidence for developing tailored policies and programs to improve the health of corporate and private taxi drivers

Risk Factors Influencing Cyberbullying Perpetration among Middle School Students in Korea: Analysis Using the Zero-Inflated Negative Binomial Regression Model

This cross-sectional descriptive study identified risk factors and predictors related to the perpetration of and potential for cyberbullying among adolescents, respectively. The analysis included a zero-inflated negative binomial regression model. Data were assessed from 2590 middle-school student panels obtained during the first wave of the Korean Child and Youth Panel Survey 2018. Of these respondents, 63.7% said they had not experienced the perpetration of cyberbullying. However, a subsequent count model analysis showed that several factors were significantly associated with cyberbullying, including offline delinquency, aggression, smartphone dependency, and smartphone usage on weekends (either 1–3 h or over 3 h). A logit model analysis also showed several predictive factors that increased the likelihood of cyberbullying, including gender (boys), offline delinquency, aggression, smartphone usage during weekdays (1–3 h), computer usage during weekends (1–3 h), and negative parenting. These identified risks and predictors should be useful for interventions designed to prevent the perpetration of cyberbullying among middle school students

Purification, crystallization, and X-ray crystallographic analysis of Vac8p complexed with Atg13p from Saccharomyces cerevisiae

Vac8p is a vacuolar protein that plays pivotal roles in both vacuole inheritance and the formation of nucleus vacuole junction (NVJ) in yeast. The Vac8p directly interacts with Atg13p, a component of the autophagy machinery, and mediates cytoplasm-to-vacuole targeting (Cvt) pathway, resulting in the maturation of aminopeptidase I (Ape1p). Here, we coexpressed and purified Saccharomyces cerevisiae Vac8p complexed with Atg13p in Escherichia coli bacteria cells, and crystallized the complex proteins under the condition of 25% (v/v) PEG 400, 100 mM Tris pH 8.5, 2% (v/v) Ethylene glycol, 2% (w/v) PEG 3350, 1.5% (w/v) PEG 20000, 5 mM DTT at 293K. X-ray diffraction data of the crystals were collected to 2.9 Å resolution at the synchrotron radiation. The crystals belong to the orthorhombic space group P212121 with unit cell parameters a = 62.7 Å, b = 92.4 Å, and c = 139.9 Å. The asymmetric unit contains one Vac8p-Atg13p heterodimer with a corresponding VM of 2.92 Å3 Da-1 and solvent content of 57.8%
