Objectives: The purpose of this study is to empirically verify the difference between traditional gender role attitude and realistic dual earner attitude. Most preceding studies analyzed gender role attitude by summated rating scale while few studies have been conducted on the difference between traditional gender role attitude and dual earner attitude. Method: By using the 9th Korea Welfare Panel Data (year 2014), this study extracted households of married couples and with children in working age (18 through 64 years of age) who are the main subjects in work-family relationship. First, this study classified traditional group and modern group in their gender role attitude and passive group and active group in their dual earner attitude and by crossing these attitudes, drew out 4 gender role/dual earner attitudes. For analysis, this study investigated frequency of attitude types through descriptive statistics. By conducting ANOVA, study verified if there are significant differences in the satisfaction with family relationship depending on the types of gender role/dual earner attitudes. Lastly, study examined the effect of socio-economic status and demographic characteristics on the types of gender role/dual earner attitudes by conducting multi-nominal logistic regression analysis. Results: As the result of analysis, first, half of respondents belonged to 'equal-role-oriented type' who has modern gender role attitude and active dual earner attitude. However, there were not a few 'dual-earner-avoiding type' who has modern gender role attitude but passive dual earner attitude and 'incongruous attitude type' who has traditional gender role attitude but active dual earner attitude. Next, 'incongruous attitude type' had significantly low level of satisfaction with overall family life, relationship with spouse and relationship with children than other attitude types. Lastly, those whose incomes belong to poor strata, those who are high school graduates and lower, males and those who are over the age of 60 had significantly higher probability of belonging to 'incongruous attitude type.' Conclusion: The results of analysis demonstrate that the difference between gender role attitude and dual earner attitude is an important matter and since 'incongruous attitude type' exhibits low level of satisfaction with family relationship, scrupulous policy approaches are required for those who have high possibility of belonging to 'incongruous attitude type.'

Objectives: This study aims to investigate the effect of marital relationship on parenting stress among dual- and single-earner families. In particular, this study focuses on the interaction effect of marital relationship and father's child-rearing involvement on the parenting stress. To access factors associated with parenting stress, we included marital satisfaction and marital conflict as the dimensions of marital relationship in this study. Method: We employed data from the 5th wave of the Panel Study of Korean Children(PSKC) data. Our analysis sample consisted of 1,515 parents having at least one child aged under 4 years. Also, this study conducted descriptive statistics and multiple regression analysis. Results: First of all, marital satisfaction and marital conflict were significantly related to parenting stress for both mother and father in dual-earner families. While both indicators were significantly related to parenting stress for father, marital conflict only was a significant predictor for mother in single-earner families. Second, father involvement was a significant predictor for parenting stress for father in both dual- and single-earner families. Third, interaction effects were found between father involvement and marital conflict in the dual-earner families and between father involvement and marital satisfaction in the single-earner families. Conclusions: Based on the results, we recommended programs designed to enhance father's child-rearing involvement such as parenting education and community-based campaign. In addition, we recommended that policy and practice need to identify marital relationship dynamics to promote father's involvement and to reduce marital conflict in both dual- and single-earner families accordingly.

This study has surveyed 379 social workers to recognize how much they believe their behaviors are ethical related to dual relationship and how many they have experienced dual relationships with their clients. In addition, we also examined if there were significant differences in social workers' beliefs and experiences according to their socio-demographic characteristics and organizational properties. To accomplish this purpose, we conducted frequency analysis, single sample t-test and one-way analysis of variance focusing on sexual, bartering and private relationships. Respondents tend to have a little permissive attitude about dual relationships while they little experienced of them. Social workers's beliefs and experiences are different depending on gender, education level, work experience, position, training experience of ethics and service target. From these results, it suggested that code of ethics for social workers and the curriculum of social work ethics should be revised reflecting on present field situation and inspiring ethical sensitivity.

Objectives: The purpose of this study is to analyze the relationship between dual smoking and mental health. Methods: This study was conducted on 5,879 Korean adults, and a logistic regression analysis was conducted to investigate the relationship between smoking type and mental health. Results: The types of smoking were surveyed as 'dual smoking' 6.1%, 'electronic cigarette' 1.7%, 'general smoking' 12.1%, and 'non-smoking' 80.1%.. The risk of diagnosing depression in the dual smoking group was 2.87 times higher than in the non-smoking group, the risk of depression was 1.66 times higher than in the non-smoking group, and the risk of stress was 1.62 times higher. Conclusion: Even in adulthood, health education such as smoking prevention education and smoking cessation education should be conducted.

In this paper, we present a new construction for self-dual codes that uses the concept of double bordered construction, group rings, and reverse circulant matrices. Using groups of orders 2, 3, 4, and 5, and by applying the construction over the binary field and the ring F₂ + uF₂, we obtain extremal binary self-dual codes of various lengths: 12, 16, 20, 24, 32, 40, and 48. In particular, we show the significance of this new construction by constructing the unique Extended Binary Golay Code [24, 12, 8] and the unique Extended Quadratic Residue [48, 24, 12] Type II linear block code. Moreover, we strengthen the existing relationship between units and non-units with the self-dual codes presented in [10] by limiting the conditions given in the corollary. Additionally, we establish a relationship between idempotent and self-dual codes, which is done for the first time in the literature.

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.

On the basis of the equity theory, as the couple perceives their relationship is equitable, they tend to make decisions jointly and are satisfied with their family lives. Therefore this study is aimed to identify the relationship among perception of equity, decision-making styles and family life satisfaction in dual-career couples. As a result of analyzing the cause-effect relationship, it shows that many socioeconomic$.$psychological variables have direct indirect impact on family life satisfaction through medium factor, so this study proves the application of the cause-effect modes. However the influence of the perception of equity of wives were higher than husbands.

The wear behavior as the hardness of the sliding elements on the dry wear has been investigated using a dual leaf-spring. The materials of the specimens are used as ten kinds along their hardness. In this study, both upper and lower specimens have been used the same materials. Using experimental data, we figured the relationship between wear coefficient and friction coefficient, and the relationship between wear coefficient and friction temperature. Also we combined friction temperature and friction coefficient instead of wear coefficient. We substituted this into wear equation of Archard. The result had been derived a newly wear equation in using dual leaf-spring wear system.
