The purpose of this study was to research the effects of socio-demographic factors and values in each group on satisfaction with life by categorizing the activity types of the elderly into volunteer work and economic activities. The subjects of this study were 60 years an old higher. The questionnaires were categorized depending on activity types and collected. The voluntary work group consisted of 201 people (76 males, 36.8% and 125 females, 62.2%), The economic activity group consisted of 219 people (127 males, 58.0% and 92 females, 42.0%). The SPSS 14.0 Windows program was used to analyze data. Frequency, average, standard deviation, factor analysis, Pearson correlation coefficient, t-test, One-Way ANOVA analysis, and hierarchical multiple linear regression were analyzed. The major findings of this study indicate that the elderly in the voluntary work group have a high collectivism value, higher income earned by performing economic activities, and good cognitive health affected by a high satisfaction with life. From these research results, it was proved that a collectivism value is a common factor that affects satisfaction with life in both of the economic activity group. Those who were older had a traditional collectivism value. The voluntary work group showed a stronger collectivism value and higher satisfaction with life than the economic activity group. Thus, the diverse types of voluntary work should be developed and a systematic system should be established as methods for improving quality of life and satisfaction.

This study analyzed the cause of Corona Blue and tried to find out ways to improve the mental health of our society. The external activities decreased and the household economy got worse after COVID-19, so Corona Blue increased. The media use and the negative media information problems increased Corona Blue. The online activities had no effects. In order to relieve Corona Blue, it was suggested to increase the external activities personally, to make the social and economic conditions of women and the economic weaker better, to improve the quality of media disaster information, and for the media consumer to use the media properly.

The purpose of this study is to examine how female labor force participation, family policies, and gender equality are related to fertility rate across countries. Multiple measures has been collected from various data sources(such as OECD, UNDP, and WVS) and the panel data set which includes (mostly) OECD countries range from 1990 to 2019 are analyzed. The major findings are as follows. First, based on OECD countries samples, female labor force participation is positively associated with the fertility rate, which implies that women's labor force participation does not lead to a reduction in fertility rate. Second, the length of paternity leave is positively associated with fertility rate whereas the direction is the opposite for the relationship between the length of maternity leave and fertility rate. This is attributed to the possibility that a longer period of maternity leave incurs the a higher opportunity cost of earning income, which leads to a reduced fertility rate. Third, countries with higher gender inequality index tend to have a higher fertility rate. Similarly, countries with higher gender equality value have a lower fertility rate. When the gender equality value is devideed into three sub-categories, education, politics, and employment, the gender equality value in education is the only sub-category which is negatively associated with the fertility rate. This study confirms that female labor force participation may not be a contributing factor in the lowering of fertility rate but instead can be positively associated with the fertility rate. Also, the results show that family policies or gender equality values can be significantly affect fertility rate.

This paper develops a dynamic structural equation model, which captures relationships among socio-demographics, activity participation(i.e., time use) and travel behavior in consideration with time variation effects. The data used in developing the model are two waves(the year 1991 and 1992) from Puget Sound Transportation Panel (PSTP). which is surveyed in Puget Sound Region in United States. The PSTP is widely used in transportation behavior analysis and includes various information of traveler's socio-economic, travel patterns, and activity participation. In the model, we use 10 endogenous variables including activity participations and travel behaviors and 10 exogenous variables composed of time variant and invariant traveler's socio-demographic variables. The empirical model shows that strong relationships exist not only between socio-demographics and travel behavior, but between waves. We also confirm needs of panel data set to identify and understand time variation effects and travel behaviors.

This paper verifies if the engagement in social activities mediates the effects of human, economic and cultural capitals on successful aging in elderly citizens. The questionnaire survey data collected from 356 elderly citizens aged 65 and over in Busan undergoes structural equation modeling for analysis. The analysis highlights the following. First, human and cultural capitals influence social engagement activities whereas economic capital does not. Second, economic capital affects successful aging whereas human and cultural capitals do not. Third, engagement in social activities impacts on successful aging. Fourth, engagement in social activities mediates the effects of human, economic and cultural capitals on successful aging. Based on these findings, this paper makes suggestions for improving the capitals and social activities of the elderly for successful aging.

This study predicts the economic activity level of the elderly in Korea using various machine learning methods. While the previous studies mainly focused on testing the relationship between the economic activity level and the life satisfaction or the social security system, this study aims at the accurate prediction on the economic activity level of the elderly using various machine learning methods and the forecast combination. Dependent variables such as the activity rate, employment rate, etc and independent variables such as the income, average wage, etc compose the dataset in this study. Five different machine learning methods and two forecast combinations are applied to the given dataset. The prediction performances of the machine learning method and the forecast combination varied across the dependent variables and prediction intervals, but it was found that the forecast combination was relatively superior to other methods in terms of the stability of prediction. This study has significance in that it accurately predicted the economic activity level of the elderly and achieved the stability of the prediction, raising practicality from a policy perspective.

This study will be used as basic data for the prevention of suicide ideation and the promotion of oral health of economic activity by studying the data of National Health and Nutrition Survey in Korea to find out the relationship between the oral health and suicidal ideation in Korea economic activity. The collected data was based on the IBM SPSS Statistics 20.0 program, and the analysis method is to analyze the frequency of complex samples, Chi-square test of complex samples and logistic regression analysis of complex samples were performed. According to the study, discomfort chewing 2.49 times higher in relation to oral health and suicidal ideation. Therefore, it suggests the need for oral health care to prevent suicide ideation of economic activity.

본 연구에서는 기술표준원이 (주)코리아데이터네트워크에 의뢰하여 작성된 설문조사결과를 활용하여 기업의 표준화활동 결정요인을 분석하였다. 표준화활동을 유형(혹은 범주)에 따라 기업의 전사적 표준경영, 국내표준화활동, 국제표준화활동, 인증획득 등으로 구분하였고, 그 결정요인으로 기술혁신활동(R&D와 특허출원), 기업규모, 수출, 네트워크, 기업조직특성, 산업별 특성 등을 고려하였다. 분석된 표본은 제조업에 속한 636개 기업으로 정성적 분석방법인 로지스틱 회귀모형 (logistic regression)을 사용하였다. 분석결과, 첫째 기술혁신활동 변수 중 R&D집약도는 국제표준화활동을 제외하고 표준화활동에 영향을 미치지 않는 것으로 나타났다. 둘째, 특허출원은 전사적 차원에서의 표준경영과 인증획득활동에 대해 정 (+)의 유의한 효과를 보여 주었다. 셋째, 소기업과 대기업보다는 중간규모의 기업에서 전사적 차원에서의 표준경영과 인증획득활동이 활발하다는 역U자 가설이 성립하는 것으로 분석되었다. 넷째, 표준화에 대한 경영진의 관심은 모든 표준화활동의 유형에 대해서 중요한 결정요인으로 나타났다.
