Recently, AI, big data, and IoT technologies are being used in various solutions such as fire detection and gas or dangerous substance detection for safety accident prevention. According to the status of occupational accidents published by the Ministry of Employment and Labor in 2021, the accident rate, the number of injured, and the number of deaths have increased compared to 2020. In this paper, referring to the dataset construction guidelines provided by the National Intelligence Service Agency(NIA), the dataset is directly collected from the field and learned with YOLOv4 to propose a collision risk object detection system through object detection. The accuracy of the dangerous situation rule violation was 88% indoors and 92% outdoors. Through this system, it is thought that it will be possible to analyze safety accidents that occur in industrial sites in advance and use them to intelligent platforms research.

This purpose of this study is to present a new theoretical framework on birthrate recovery in advanced countries in the 21st century. As a result of socioeconomic development and individualism diffusion, the central axis of the family has transformed from the vertical axis of the father-son relation, to the horizontal axis of the husband-wife relation. This process is divided into 2 stages. In the industrialization stage, a nation or a society achieves equality of the individual in family formation, including marriage or divorce. In the post-industrialization stage, it accomplishes the couple equality in family maintenance, including child rearing and household labor. This paper grouped 33 OECD member countries as post- industrialization countries and 103 countries as industrialization countries. This study utilizes 6 variables affecting marriage and childbearing based on previous research. Research results find that during the industrialization stage, the birthrate falls as the education level of women is higher. In the post-industrialization stage, the birthrate rises as gender equality level is higher.

Objectives: The purpose of this study was to examine the relationship between the differences in employment status and self assessed health in Korea. Methods: We analyzed 4 year follow-up data generated by the Korean Labor and Income Panel Study(KLIPS), which was conducted on 1,207 men and 582 women who had undergone a change in employment status. The study subjects were placed into 1 of the following 4 groups based on their employment history; Non-precarious workers, Precarious to non-precarious workers, Non-precarious to precarious workers and Precarious workers. Logistic regression was then used to examine the relationship between the changes in employment status and self assessed health. Results: When males were considered, self assessed health was better among the precarious to non-precarious workers (OR 1.58, 95% CI=1.57-1.60) and the precarious workers (OR 1.29, 95% CI=1.28-1.30) than in the non-precarious workers, after adjusting for age, socioeconomic status (education level, occupational class, marital status, average equivalent household income and average number of hours worked per week), health behavior (smoking, drinking and exercise) and medical service access (regular medical examination, have chronic disease or hospitalized within 1 year). When female workers were considered, the precarious to non-precarious workers (OR 1.89, 95% CI=1.86-1.92), non-precarious to precarious workers(OR 1.24, 95% CI=1.23-1.26) and precarious workers (OR 1.27, 95% CI=1.25-1.28) all reported poorer health than the non-precarious workers after adjusting for the aforementioned factors. Conclusions: This study showed that changes in employment status were associated with differences in self assessed health among men and women. Specifically, the results of this study showed that a corresponding positive outcome based on self assessed health was greater for employees that changed from precarious to non-precarious jobs and for male employees with precarious jobs., whereas female employees with non-precarious jobs had higher self assessed health. However, additional longitudinal studies on the health effects of employment status should be conducted.

The study analyzes divorce rates in Korea and makes suggestions for the future research of divorce rates. Based on the data from Korea Statistical Information System (KOSIS) of the National Statistics Organization, trends for divorce rates change and the relations between divorce rates and macro environmental factors are analyzed. Macro environmental factors include socioeconomic factors such as, Korean War, Vietnam War, oil shock, IMP economic crisis and gross national income (GNI), whereas demographical factors include population structure, rates of female labor participation, and geographical location. The principle characteristics of divorce rates are as follows: 1) the Crude divorce rates (CDR) and the number of divorced had been increased from 1970 to 2004, then the trend changed to a decrease; 2) the slope of the change were the highest during 1998 to 2004 after the IMP economic crisis. The relations between socioeconomic factors are as follows: 1) during the war there was a small increase of CDR for a short period of time; 2) the economic crisis of the nation tend to increase the CDR, while the IMP economic crisis had a strong impact on an increase of CDR because of the interaction effect among the population structure, women's sex role changes as well as the level of standard of living. The increase in CDR from 1990 to 2000 can be explained partly by the population of baby Boomers passing through their marriage and divorce process. The number of population residing in the rural area and the middle class households, and the mobility of population also had an impact on the divorce rates changes. The recommendations for the future research were as follows: 1) the need to develop new divorce statistics that are based on a marriage cohort or a birth cohort because family behavior is a mixture of personal, social and political responses, and because CDR is not an accurate measure of divorce rate since it was influenced by population structure; 2) the need to include micro personal factors as well as macro social factors in a model to find an interaction effect between those variables.

This paper seeks to empirically analyze the effect of WLFP on fertility in Korea using the 1985~2010 Korean Population and Housing Census 1% Sample data. The results show that except in year 1985(+0.336) WLFP had a significant negative effect on fertility rates in years 1990, 2000, 2005, 2010. The size of the negative effect increases from 1990(-0.611) to 2005(-2.273). In 2010(-0.793), however, the negative effect considerably decreases when compared with the 2005 result. This alleviation is partially due to policies that have promoted compatibility between work and family life. Policy makers should therefore focus on expansion of policies for the compatibility of work and family, and give more attention to increasing take-up rate for the current policies.

In this study we find that relatively high minimum wages should make the employment ratios of youth, old, and woman lower very significantly in those regions concerned, futhermore, make the overall employment ratios of those regions lower also by using a proxy variable, the Regional Minimum Wages-Half Median Wages Ratio which represents well the very stable differential structure of wage distributions among regions in Korea. In large Cities those effects become much stronger. But we find also that those effects on the rates of regional unemployment are somewhat double-faced except the case of youth because of the probable generating of many discouraged unemployed among the old and women. So, we can conclude that because of the differential regional economic situations it is not sustainable to increase the overall minimum wages uniformly and excessively and strongly necessary to explore ways toward introducing the proper system of regional minimum wages.

The economic penalty of care and gender inequality reinforce each other. Unequal distribution and treatment of care are at the basis of gender inequality. Care creates economic penalty that deepen gender inequality. Those who perform care work tend to take the position of the vulnerable in socio-economic power relations. Due to their weak position, it is difficult for them to voice out a fair treatment and reward for their work. As a result, care workers both at home and in the public sector suffering from lower economic value of care are positioned in unequal gender relations with more vulnerable socioeconomic status. The basic income system may have the potential to mitigate multifaceted gender inequalities in our society. For the introduction of basic income to help realize the real freedom for women, it is necessary to understand unique natures of care work and tackle economic penalties of care work. This paper examines the relationships between care penalties and basic income, focusing on the debate on the introduction of the basic income system. We argue that if the economic penalties caused by unique natures of care work are not eased or resolved, the introduction of the basic income may not contributes to alleviating gender inequalities.

Precarious employment is negatively associated with mental health including depression. The aim of the study is to suggest the multidimensional definition of precarious employment and examine its impacts on depression. Using the fifth save of the Korean Working Condition Survey, we first measured six different dimensions of employment precariousness: temporariness, disempowerment, vulnerability, difficulty exercising rights, unpredictability of working times, and low wage. All of six precariousness indicators consisted of a scale from 0 to 100. Then, we conducted logistic regression to examine the association between employment precariousness and depression. For men, the risk of depression increased by 3.1%, 1%, and 0.5%, respectively, for each one point increase in vulnerability, difficulty in exercising rights, and unpredictability of working times. For women, the risk increased by 0.5%, 2.3%, and 0.8%, respectively, for each one point increase in temporariness, vulnerability, and difficulty in exercising rights. Our findings suggest that not only a secure employment contract, but also their substantive labor rights should be guaranteed for health for workers.

Korea is facing a significant problem with historically low fertility rates, which is becoming a major social issue affecting the economy, labor force, and national security. This study analyzes the factors contributing to the regional gap in fertility rates and derives policy implications. The government and local authorities are implementing a range of policies to address the issue of low fertility. To establish an effective strategy, it is essential to identify the primary factors that contribute to regional disparities. This study identifies these factors and explores policy implications through machine learning and explainable artificial intelligence. The study also examines the influence of media and public opinion on childbirth in Korea by incorporating news and online community sentiment, as well as sentiment fear indices, as independent variables. To establish the relationship between regional fertility rates and factors, the study employs four machine learning models: multiple linear regression, XGBoost, Random Forest, and Support Vector Regression. Support Vector Regression, XGBoost, and Random Forest significantly outperform linear regression, highlighting the importance of machine learning models in explaining non-linear relationships with numerous variables. A factor analysis using SHAP is then conducted. The unemployment rate, Regional Gross Domestic Product per Capita, Women's Participation in Economic Activities, Number of Crimes Committed, Average Age of First Marriage, and Private Education Expenses significantly impact regional fertility rates. However, the degree of impact of the factors affecting fertility may vary by region, suggesting the need for policies tailored to the characteristics of each region, not just an overall ranking of factors.

In Korea home economics in the secondary school level was only taught to girls until 1995. So. home economics education only for girls was criticized to sexist education by the feminists. According to the 6th revision of curriculum. home economics has been taught to girls and boys. But some of curriculum developers raises another questions on home economics education. They argue that home economics is a subject which prepares students for the demand of their day-to-day lives. but they can manage their lives well without school learning. The purpose of this study is to explore the educational values of home economics in secondary education from the gender-sensitive approach. For this study, a literature survey on the nature of home economic education in secondary education and the content analysis on 12 secondary school textbooks of Home Economics were employed. The results are as follows : First, the educational values of home economics education should not be underestimated. The aims of home economics education is to help students grew into a independent person by managing their daily lives. The home is charged with fostering a side of our life which we might call Personal, private. intimate and nurturing. The management of the home needs good skills and attitudes. and many knowledges on the child rearing, family relation, marriage, love and sex, which can not be successfully acquired without school learning. And home economics education for boys and girls can help break down the barriers between the sexes because it can change the attitudes of students regarding the private sphere. which is traditionally where women have worked. Second. most of contents of Home Economics were composed of the women-oriented contents. There was a trend still describing that domestic labor mainly be carried out by mother. And the ideas that only the family consisting of two parents and their children is normal were founded. Finally directions of development of the Home Economics Education are suggested.
