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.

The causes of aortic dissection are usually hypertension, connective tissue disease such as Marfan syndrome, congenital valvular abnormality such as bicuspid aortic valve, iatrogenic injury, pregnancy and drugs. Previous studies have shown that 50% of all dissections in women less than 40 years age were associated with pregnancy. Almost all aortic dissections during pregnancy occur during the third trimester or during labor and delivery. Marfan's syndrome is a particularly important predisposing factor for aortic dissection during pregnancy. We report here on a case of surgical treatment for acute type II aortic dissection in a Marfan syndrome patient who was 24 weeks pregnant, and we include a review of literature.

The increasing prevalence of inactivity and obesity, along with aging, has implications on work capacity of labor force. This study reports the relationships between activity level and BMI by age with objectively measured physical workload. Data were examined from a sample of 19 481 Finnish employees using an estimate of minute-to-minute oxygen consumption based on R-R interval recordings. The mean estimated %VO₂max during the working day was 12.1 (±3.6) and 15.1 (±4.5)% for men and women, respectively. Based on a linear model, the mean %VO₂max increased by 1.5%-unit per 10-year increase in age, by 2.1%-unit per 5 kg/㎡ increase in BMI, and decreased by 1.6%-unit if improving physical activity class by two (p < 0.001 for all). Overweight and obesity, together with inactivity, notably increases workload throughout the career, even though at young adulthood, the daily workload is almost the same for each person regardless of the BMI, activity level, or gender. This study highlights the importance of regular physical activity and normal weight in protecting the worker from excessive physical (cardiovascular) workload during the whole working career.

Objectives : A safety issue on acupuncture and moxibustion treatment during pregnancy is as important as effectiveness. To establish a rationale and research strategy for future studies, a traditional literature review was performed to summarize how and for what conditions acupuncture and moxibustion treatment was given during pregnancy. Methods : An extensive traditional literature search for acupuncture and moxibustion treatment during pregnancy was conducted in texts on acupuncture and moxibustion, obstetrics and gynecology, and comprehensive medical texts. Treatment conditions, methods, and contraindications were summarized and tabulated. Results : Twenty-eight books were included in our review. Most frequent description of acupuncture and moxibustion treatment use during pregnancy was for difficult delivery including breech presentations; commonly used acupuncture points for difficult labor included LI4, SP6, BL67, BL60, KI6, ST30, SP12, LR4, LR3, PC6, CV3, CV14, KI13, and GB21, indicating that they may have to be avoided during pregnancy. Descriptions of other symptoms or conditions were sparse. For habitual abortion or recurrent miscarriage, moxibustion on GV4, BL23, CV3, KI8, and KI2 was indicated. A combination of LI4 and SP6, and CV4 were contraindicated during pregnancy consistently across the reviewed books. Conclusions : Our traditional literature review has shown that the use of acupuncture and moxibustion treatment during pregnancy has been limited. Given that more and more pregnant women are interested in safe and effective treatment, further research of acupuncture's safety and efficacy during pregnancy is urgently needed.

The objective of our study is investigating the effects of the minimum wage on a producer price index (PPI) and selected restaurant menu prices. As an identification strategy, we exploit inter-industrial and inter-regional variations in the share of workers who are affected by the minimum wage. Estimation results show a significant relationship between the share of workers affected by the minimum wage and prices. Specifically, a PPI and selected restaurant menu prices tend to rise by 0.77~1.68% and 0.16~1.86%, respectively as the share of workers affected by the minimum wage increase by 1%p. These estimates imply that during the period of our analysis 0.82~3.01% and 4.45~47.04% of overall changes in a PPI and selected restaurant food prices are associated with the adjustment in the minimum wage.

South Korea and Japanese governments have never responded cooperatively to North Korea cyber threats in the past 10 years or even before that. There are two reasons: First, The historical and political conflicts between the two countries were so deep that they did not discuss their mutual needs. Second, officially, Japan had not been subjected to a North Korean cyberattack until 2022 . In particular, the issues of comfort women and forced labor during World War II were holding back the reconciliation between the two countries. With the inauguration of the Yoon Seok-yeol administration, Korea-US relati ons improved dramatically. Tensions in Northeast Asia reached their peak due to the conflict between the US and China. It has become a situation where peace cannot be garaunteed without close cooperation between Korea and Japan led by the United States.

This study was aimed to implement and evaluate worksite nutrition counseling for industrial workers with hyperlipidemia in Kyung-buk area. Forty-six subjects consisted of 41 men and 5 women who were diagnosed hyperlipidemia though health examination had their average age, 40.3$\pm$ 6.0 and half of them were office workers and one third labor workers. Twenty-eight subjects had fatty liver with or without other complications and six had gastric problems. The subjects were interviewed using questionnaires on food habit, food frequency, smoking, drinking and exercise, and they were given nutrition counseling which was continued for 7 months. Desirable food selections were practiced using foods or food models and various written materials individually or as group during lunch times and breaks. After counseling, smoking and drinking were reduced and exercise and food habits were improved. Average levels of initial serum total cholesterol(T-Chol), HDL-cholesterol(HDL-Chol) and triglyceride(TG) were 214$\pm$ 44, 45.07$\pm$ 7.14 and 281$\pm$ 13mg/dl respectively and were not changed significantly except 2.30$\pm$ 7.04mg/dl increase of HDL-Chol(p<0.1) after nutrition counseling. However, subjects who improved their food habits and smoking, drinking and exercise habits had higher tendency to have reduced serum T-Chol and TG levels compared with those who drank less. Food habit score was negatively correlated with serum TG levels(r=-0.378, p<0.01). It is concluded that an efficient and regular nutrition counseling by dietitian at worksite is beneficial for health of industrial workers.
