Associations of combined work schedules and atypical working hours with mental health among South Korean police officers
Atypical working hours, including long working hours and weekend work, are established psychosocial risk factors for poor mental health and suicide in the general working population. Despite South Korea’s demanding working environment—characterized by extended hours—the mental health effects of combined atypical working hours and work schedules remain poorly understood, particularly in high-risk occupations such as policing. This study compared m…
Comparison of mortality prediction models for road traffic accidents
This study presented the results of an empirical comparison of the validity of sampling techniques and classification algorithms that affect the accuracy of imbalanced samples by combining two techniques. The findings could be used as reference data in classification analyses of imbalanced data in the medical field
Comparison of Prediction Models for Mortality Related to Injuries from Road Traffic Accidents after Correcting for Undersampling
In this study, four models-logistic regression (LR), random forest (RF), linear support vector machine (SVM), and radial basis function (RBF)-SVM-were compared for their accuracy in determining mortality caused by road traffic injuries. They were tested using five years of national-level data from the Korea Disease Control and Prevention Agency's (KDCA) National Hospital Discharge In-Depth Survey (2013 through to 2017). Model performance was meas…
Comparing Logistic Regression Models with Alternative Machine Learning Methods to Predict the Risk of Drug Intoxication Mortality
(1) Medical research has shown an increasing interest in machine learning, permitting massive multivariate data analysis. Thus, we developed drug intoxication mortality prediction models, and compared machine learning models and traditional logistic regression. (2) Categorized as drug intoxication, 8,937 samples were extracted from the Korea Centers for Disease Control and Prevention (2008-2017). We trained, validated, and tested each model throu…
Exclusionary Labor and Partially Inclusionary Marriage Immigration Incorporation
Globalization has brought about significant human mobility, along with developments in IT and transportation since the early 1990s, the case of East Asia is no exception. While a huge number of workers in developing countries have been migrating to work abroad, a growing number of women have been migrating, specifically seeking to marry men in East Asia. This paper aims to elucidate which migration theories illustrate labor and/or marriage migrat…
High-risk work, cultural conflicts and labor mobility
One of the most influential theories of embedded workplace is Stephen Frenkel’s macro-, meso- and micro-linkages. Indeed, the current neoliberal economic hegemony in Korea engenders an environment in which foreign workers have the right, albeit a restricted right, to move from one job to another. However, it is far more complicated on the micro-level than he argued, if we take into consideration the nature of foreign workers, with combined workpl…
Managerial Styles, Workforce Composition and Labor Unrest
This paper investigates how labor disputes have been differentially affected by the interplay of organizational characteristics, institutional structure, work conditions, as well as the characteristics of labor force by country origin of East Asian-owned firms and location of industry in China. It also analyzes how different managerial styles such as personal (arbitrarily regulatory), authoritarian and institutionalized paternalism affect workers…
