The purpose of this paper was to investigate the relations among wife's job and family life structure of couples, and to compare them between Japan and Korea. The data for this study was obtained from a survey of 247 Japanese couples who were risiding in Osaka and 235 Korean couples in Deagu, 1992. The major findings of this study can be summarized as follow: 1. The contents of Household works is classified into three factors-daily routine houseworks, child-rearing, economic-management of household, in Korea, and into two factors-daily routine houseworks, child and economic management, in Japan. The contents of descision making is classified into four factors-husband's personal sphere, family life management, wife's personal sphere, and home economic sphere, in Korea, and three factors-husband's personal sphere, economic life management of family, and wife's personal sphere, in Japan. 2. In Korea and Japan, wife's job have not effect on couple's marital satisfaction, directly. However, wife's job contribute to husband's share of daily routine houseworks.

Electricity sales are directly measured from individual consumers, which could minimize the time gap between data collection and public announcement. Furthermore, industrial electricity sales are highly linked with production and output. Therefore, industrial electricity consumption can be used to track production and output in real time. By using the high-frequency data of industrial electricity sales, this study develops the daily electricity business index (DEBI) to capture the daily economic status. The steps used to formulate DEBI are as follows: (1)selection of the explanatory variables and period, (2) amendment of the seasonal adjustment to eliminate daily temperature and effective day effects, (3) estimation of the weighted value via variables by using PCA, (4) calculation of DEBI and commencement of validation tests. Our empirical analysis and the Hodrick-Prescott filter analysis show that DEBI is highly related to existing economic indices.

This paper examines the effects of financial crises on the long memory volatility dependency of daily exchange returns focusing on the Asian crisis in 97-98 and the Global crisis in 08-09. By using the daily KRW-USD and JPY-USD exchange rates which have different trading regions and volumes, this paper first applies both the parametric FIGARCH model and the semi-parametric Local Whittle method to estimate the long memory volatility dependency of the daily returns and the temporally aggregated returns of the two exchange rates. Then it compares the effects of the two financial crises on the long memory volatility dependency of the daily returns. The estimation results reflect that the long memory volatility dependency of the KRW-USD is generally greater than that of the JPY-USD returns and the long memory dependency of the two returns appears to be invariant to temporal aggregation. And, the two financial crises appear to affect the volatility dynamics of all the returns by inducing greater long memory dependency in the volatility process of the exchange returns, but the degree of the effects of the two crises seems to be different on the exchange rates.

This study aims to investigate the effects of restrictions in economic activity on the spread of COVID-19 in the Philippines. This research employs daily time-series data of confirmed new COVID-19 cases, Apple mobility trends (i.e., use of public transport to destinations, volume of people driving, and amount of walking to destinations) and Google community mobility (i.e., visits to transit stations, visits to workplaces, and staying-at-home) indicators covering the period February 17 to September 11, 2020. The analysis starts by establishing the correlation pattern of new confirmed COVID-19 daily infections to each independent variable. The results show negative linear correlation of the number of new COVID-19 daily infections with less visit to transit station, increase stay-at-home, less use of public transport, and less amount of walking to destinations. Interestingly, the number of new COVID-19 daily infections indicates some form of positive linear correlation with visits to workplaces and volume of people driving. Moreover, employing robust least square regression via the method of MM-estimation, major findings reveal that across mobility measures, staying-at-home has the highest impact on reducing the spread of COVID-19, followed by visiting transit stations less, less use of public transport, less amount of walking, and less workplace visits.

연구목적: 노인의 주관적 건강 수준과 ADL(Activities of Daily Living), IADL(Instrumental Activities of Daily Living)의 관계를 통해 집단 간 동질성과 이질성을 살펴보고자 한다. 연구방법: 2014년도 노인실태조사를 이용하여 주관적 건강 수준을 독립변수로 ADL과 IADL의 제한을 종속변수로 설정하였다. 로지스틱 회귀분석을 실시하였으며 성별로 비교하였다. 연구결과: 남성 노인에 비해 여성 노인이, 사회경제적 수준이 낮고 연령이 높은 노인일수록 주관적 건강 수준이 낮으며 ADL과 IADL의 제한이 있었다. 주관적 건강 수준이 낮을수록 ADL과 IADL에서 제한을 가질 확률이 높은 것으로 관찰되었다. 특히 그 관계는 여성 노인에 비해 남성 노인에서 뚜렷이 나타난다. 연구 결과를 통해 여성 노인의 취약성을 파악하는 한편, 중증도가 높은 질병에 국한해 본인의 건강 수준을 인지하는 남성 노인의 특성을 이해할 수 있었다. 결론: 노인의 삶을 이해하고 노인 정책을 시행하는데 있어 성인지적 접근과 더불어 주관적 건강 수준을 비롯한 다양한 지표를 활용하는 노력이 필요하다.

Purpose: The purpose of this study was to evaluate the association among of Activity of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), depression and isolation in disabled people. Method: The subjects consisted of 761 disabled people in Korea. Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlational statistics. Results: There were significant differences in age, cause of disability, type of disability, degree of disability, education, job, perceived health condition, and economic status between disabled people with high and low levels of ADL and IADL. Depression showed significant differences in type of disability, degree of disability, education, job, perceived health condition, and economic state; isolation showed significant differences in age, cause of disability, type of disability, education, job, residence, perceived health condition, and economic status. A significant association was identified between depression and isolation (r=.69, p<.001). Conclusion: There was a high incidence of depression in disabled men with high levels of isolation and ADL and IADL dependence. An effort to increase disabled people's ADL, IADL, and independence levels is needed, and nursing interventions should be designed and tested to increase their community involvement and decrease the sense of isolation and depression.

There is growing evidence that substance use such as tobacco or alcohol consumption influences health disparity among adolescents. Previous research papers have shown an inconsistency in the relationship between socio-economic status (SES) and substance use in adolescents. However, little is known about socio-economic differences in unhealthy behaviors among Korean adolescents. The purpose of the present study is to explore associations between SES and substance use in Korean adolescents. The analysis was performed using data from the 2009 Korean Youth Risk Behavior Web-based Survey (YRBS), which included a nationally representative sample of middle and high school students. Drinking/heavy drinking and smoking/daily smoking behavior indices were used for dependent variables, and perceived economic status, family affluence score, parents' education were used for independent variables. Chi-square test were used to compare tobacco and alcohol consumption among 3 SES groups. Logistic regression models were used to identify statistically significant socio-economic factors after adjusting other covariates. Higher perceived economic status and higher family affluence were associated with higher rates of smoking, daily smoking, drinking, and heavy drinking, while lower level of parents' education was related to higher use of tobacco and alcohol. Socio-economic status significantly influences health behaviors in adolescents, and it may consequently affect health disparity in their adulthood. Therefore, there is a need of continuous monitoring and follow-up research of health disparity among adolescents.

China has initiated a series of "economic sanctions" against South Korea, affecting Korean pop stars visiting China and Korean investments in China. Sanctions were imposed on South Korea in response to the decision of South Korea to deploy Terminal High Altitude Area Defense (THAAD) in 2016. Furthermore, the Global Daily assembled local population to boycott Korean products and investments in China. However, the Chinese Foreign Ministry has never positively confirmed these activities as economic sanctions to South Korea related to the THAAD installation. In other words, the Chinese government singled a relatively weak message via these sanctions to South Korea. As a result, the THADD implementation continued in South Korea. In the paper, I interpret China's rationale to impost puzzling economic sanctions, which have a weak resolution, to South Korea and Taiwan. As signaling theory argues, economic sanctions with insufficient resolution, which are more likely to fail, is a more provocative foreign policy. By reviewing China's sanctions usage to South Korea and Taiwan, I propose arguments of bureaucratic competition to answer why China launched such sanctions to other countries: those are caused by domestic institutions who are seeking reward from the Communist Party of China. By comparing shifts of leadership between domestic agencies, the paper provides evidence to support the proposed argument. I also include two alternative explanations to strengthen the proposed argument, albeit connecting the paper with other two larger streams of research, which address analyses of China's aggressive foreign policies as well as the domestic politics of economic sanctions.
