The purpose of this study is to investigate (1) the relationship between gender-role attitude and psychological well-being related to the division of household labor and (2) the effect of congruency between gender-role attitude and the division of household labor on psychological well-being for the elderly. In this study, independent variable is gender-role attitude, mediating variable is the division of household labor and dependent variable is psychological well-being. Psychological well-being consists of depression and happiness. The hypotheses of this study are as follows: 1) Gender-role attitude affects psychological well-being of the elderly. The more egalitarian gender-role attitude, the higher degree of psychological well-being, whereas the more traditional gender-role attitude, the lower degree of psychological well-being. 2) The division of household labor influences psychological well-being of the elderly. The higher degree of division of household labor is likely to show the higher degree of psychological well-being. 3) The congruency between gender-role attitude and the division of household labor affects psychological well-being. As the relationship between gender-role attitude and the division of household labor is more congruent. psychological well-being increases. The results of the study are summarized as follows: 1) There is no relation between gender-role attitude and psychological well-being for the elderly. 2) The division of household labor affects psychological well-being for husband. The higher degree of division of household labor, the higher degree of psychological well-being. The result shows that husbands are involved in household labor involuntarily. 3) Congruency between gender-role attitude and the division of household labor affects psychological well-being. As the relationship between gender-role attitude and the division of household labor is more congruent, the degree of depression decreases. 4) Wives participate in most of household labor. Gender segregation in household labor is found in elderly family. 5) Health, income, network of children or sibling, and community network affect psychological well-being. The healthier, higher income and stronger network are likely to show the higher degree of psychological well-being.

This study examined the effects of the division of household labor on the marital satisfaction of husbands and wives in dual-earner families. Data were collected from 193 couples in dual-earner families; the questionnaire measurements were based on recommendations from the literature review. The questionnaire consisted of inquiries concerning gender role attitudes, marital communication efficiency, division of household labor, satisfaction in the division of household labor, and marital satisfaction. Each of these categories had an individual measurement scale that enabled measurement of its impact on marital satisfaction. The major findings of this study are as follows: The couples in dual-earner families showed egalitarian gender role attitudes and high levels of marital communication efficiency. They also reported high levels of satisfaction with their division of household labor and their marital lives. Wives in dual-earner families had more egalitarian gender role attitudes compared with their husbands, and husbands perceived themselves to be investing more time in performing household chores (that is, in the division of household labor) than was perceived by their wives. Husbands were also more satisfied with the division of household labor and marital life compared to their wives. Finally, hierarchical multiple regression analysis revealed that satisfaction in the division of household labor and in marital communication efficiency (as perceived by the couples) significantly predicted husbands' marital satisfaction. On the other hand, wives' age, marital communication efficiency, and the differences in the division of household labor (as perceived by the couples) significantly predicted wives' marital satisfaction.

This study focused on Japanese families engaging in childrearing to discover changes in their daily lives, such as in the role division between husband and wife and hours spent on housework and childcare, caused by the unexpected crisis of COVID-19. An empirical analysis attempted to determine whether changes in the working environment, such as working and commuting hours, affected the role division between husband and wife, as well as housework and childcare hours spent. The data analyzed were extracted from the 2021 "3rd Survey on Changes in Lifestyle Awareness and Behavior Due to the Impact of COVID-19" conducted by the Japanese Cabinet Office. A total of 983 couples aged 20 or older, living with their spouse, having at least one child under the age of 18, and both employed were selected. The analysis results were as follows: First, the division of roles between husband and wife changed in the direction of increasing the husband's role in housework and childrearing. Second, the decrease in working and commuting hours increased the husband's role. Third, housework and childcare hours were more clearly related to changes in the working environments of husbands and wives than to changes in role division between husband and wife. In conclusion, changes in men's working and commuting hours had a greater impact on role division, as well as housework and childrearing hours in the family, than changes in women's working and commuting hours. In the future, an analysis that considers labor market factors is necessary.

The purpose of the study was to investigate the wife and husband role division in household financial management between dual-income household and single-income household. Household financial management included the following five categories: financial planning, consumption/expenditure management, savings/investment management, risk management and credit management. Data for this research was collected through 610 married women living in Seoul, Korea. Using SAS-PC program, Chi-square and t-test Analyses were executed. The results showed that dual- and single-income households tend to have different perspectives on marital role division in household management. Wives of dual-income households had more significant roles in financial management rather than wives of single income households. Especially, wives of dual-income managed more active credit management and saving/investment management. On the other hand, wives of single-income households played a major role in making decision over cheap items than that of wives of dual-income household.

Turnip yellow mosaic virus (TYMV) RNA has two hairpins in its 5' untranslated region (5'-UTR). To investigate the role of the hairpins in replication of TYMV, mutants lacking one or both of the two hairpins were constructed. The TYMV constructs were introduced into Chinese cabbage by an Agrobacterium-mediated T-DNA transfer method, called agroinfiltration. Analysis of total RNA from agroinfiltrated leaves showed that replication of the mutant TYMV RNA lacking both hairpins was about 1/100 of wild type. This mutant was also impaired in systemic spread. Deletion analysis of each hairpin revealed that both hairpins were needed for maximal replication. The deletion analysis along with sequence modification of the hairpin structure indicates that the second hairpin plays a role in efficient long-distance systemic movement of TYMV.

Purpose - This study examines the impact of company ownership nature and of the dual role of CEO and board chair on R & D investment intensity, as well as the moderating effect of this dual role. Most previous research focused on the impact of the dual role of CEO and board chair on firm performance. Design/methodology/approach - This study uses A-share companies listed on the Shenzhen and Shanghai stock exchanges in China from 2008 to 2017. The univariate and the multivariate regression analysis were hired In order to analyze the data. Findings - The results show that there is a significant negative relationship between state-owned companies and R & D investment intensity. In addition, there is a significant positive relationship between the dual role and R & D investment intensity. The effect of state ownership on R & D investment intensity is more negative when CEO-board chair duality exists. This means that in case of state-owned companies, if CEO serves as the board chair, the propensity to invest in R&D is further reduced. Research implications or Originality - This is a pioneering study that considers the joint effect of state-owned companies and dual role on R & D investment intensity in the Chinese economy.

We have investigated the novel function of tissue transglutaminase (tTG) in the germinal vesicle breakdown (GVBD) of mouse oocyte. tTG was identified in ooplasm and germinal vesicle by immunostaining assay. Spontaneous maturation of the oocytes elevated in situ activity of tTG by over 2.5 fold at 3 hr, which was determined by a confocal microscopic assay. However, incubation with monodansylcadaverine (MDC), a tTG inhibitor, blocked the activation of tTG. The possible role of tTG in GVBD was investigated by the use of two tTG inhibitors, MDC and cystamine. MDC largely inhibited the GVBD by a concentration dependent manner. GV-stage oocytes were matured to the GVBD stage by 78% at 3 hr in BWW culture medium. However, in the oocytes incubated with MDC for 3 hr, the GVBD rates were 43 and 11% by 50 and 100 mM, respectively. MDC also blocked the entry of 70 kDa TRITC-dextran from the ooplasm to the compartment of germinal vesicle, indicating a possible inhibition of nuclear pore disassembly by MDC. The role of tTG in GVBD was further investigated by microinjection with cystamine. The control oocytes, injected with DPBS, showed about 80 % of GVBD at 3 hr. But the oocytes injected with cystamine showed 15% of GVBD at 3 hr and a little higher rate at 6 hr. In addition, the inhibition of GVBD maturation by MDC was reversible by washing. These results suggested that tTG was involved in the early event of mouse oocyte maturation

Purpose - This study aims to elucidate the status of women as consumers and observe their consumption trends in relation to culture. Research design, data, and methodology - Past studies of women as consumers were observed and their consumer behaviors were noted. The stigma of women in society and how it has impacted the market industries were examined. Additionally, the role of culture in consumerism for women were also reviewed and elucidated. Results - The stereotypical roles that are placed in women in society are still prevalent for the marketing industry and is reflected in their businesses. Additionally, the role of culture plays a significant role in the consumer behaviors of women and thus businesses should understand its intricate differences between countries. Fashion industry is one that plays a prominent role in women's consumerism and the impact of culture has a prominent impact on women's consumer habits as well. Conclusions - Additional studies should be conducted to understand the consumerisms of women in the marketing industry. Businesses should also be aware of the vastly different cultural norms of various countries and tailor to their preferences. Only through a thorough examination and understanding of the consumer behavior in women will markets be able to flourish and gain solid ground in global businesses.
