Reactive diffusion couples between Fe-5.8at.%Si and (Si wafer, $FeSi_2$, or FeSi alloy) were heat-treated at 1423k. The only layer of $Fe_3Si$ phase was formed in each diffusion couple. The width of $Fe_3Si$ layer was proportional to square root of diffusion time in each kind of diffusion couple. Growth rate of $Fe_3Si$ layer was relied on the concentration of Si in the supplied source of Si atoms. Interdiffusion coefficient of $Fe_3Si$ has been determined from the derived relation between growth rate constant and interdiffusion coefficient in this work. It was shown that the behavior of Kirkendall's void in $Fe_3Si$ layer was not affected by the kind of Si source. But solid solution $\alpha$ was formed in the diffusion couple between Fe-5.8 at.%Si and $Fe_3Si$ alloy. Kirkendall's voids in diffusional $\alpha$ were neglectively smaller than the case of $Fe_3Si$ phase growth.

The purpose of this study was to investigate the role of anxiety in mediating the influence of family of origin characteristics on subsequent relationship processes. Using Bowenian theory as a foundation, this study examined the causal relationships among gender, religion, family of origin-fusion, intimacy, intimidation, personal-trait-anxiety, couple open communication and relationship satisfaction. Results of the path analysis indicated that: (a) gender, religion, family of origin-fusion, and family of origin-intimidation were directly related to personal-trait-anxiety, (b) personal-trait-anxiety was directly related to couple open communication and not related to relationship satisfaction, (c) couple open communication was directly related to relationship satisfaction, and (d) family of origin factors were not directly related to couple open communication and relationship satisfaction; rather, as it was expected, indirect associations, through the mediation of anxiety, were found. The results generally support Bowen's intergenerational process theory, which asserts that anxiety is the mediator of the process. Limitations of the current study and suggestions for further research were discussed.

This study explored how communication between married men and women is related to marital satisfaction, and verified the relationship through the medium effect of marital intimacy. A total number of 365 married men and women in their 30s-50s were surveyed. Statistical analysis was performed using SPSS 18.0 for technical statistics, frequency analysis, and regression analysis, and parametric analysis was performed using the method by Baron and Kenny(1986). The results of the study are as follows. First, as a result of the verification of differences in key variables according to the demographic characteristics, there were significant differences in the age group, education period and household income. Second, the analysis of the relationship through regression analysis shows that the demographic factors such as age, age of the youngest child, and more importantly couple communication, and marital intimacy are influential in marital satisfaction. Third, verification of the mediation analysis revealed that marital intimacy had partial mediation with communication and marital satisfaction. Through these research results, we verified that marital communication and marital intimacy are vital in order to improve marriage satisfaction for married men and women.

This study was done to investigate the effects of family relationship on satisfaction with life in women immigrants. The participants were 346 women immigrants in S city, Chungnam province. The data were collected through self-reported questionnaires which were constructed to include such scales as satisfaction with life and family relationship. First, satisfaction with family relationship ranked in order of couple, parents-in-law, and brothers-in-law and sisters-in-law. Second, as the women immigrants were younger, and their wedding time was shorter, satisfaction with couple was higher. Third, when women immigrants were between 20 and 30 years old in age, and between 2006 and 2010 in wedding year, satisfaction with parents-in-law were higher. Fourth, when women immigrants were between 20 and 30 years old in age, and 2006 and 2010 in wedding year, satisfaction with brothers-in-law and sisters-in-law were higher. Fifth, satisfaction with life was higher for women immigrants with younger age, lower educational level, and shorter residence and wedding time. Sixth, curve term more accounted for relationship between satisfaction with parents-in-law and life. Seventh, significant predictors influencing satisfaction with life were satisfaction with couple, and brothers-in-law and sisters-in-law.

In this article, analytical solution for free vibration of micro composite laminated beam on elastic medium based on modified couple stress are presented. The surrounding elastic medium is modeled as the Winkler elastic foundation. The governing equations and boundary conditions are obtained by using the principle of minimum potential energy for EulerBernoulli beam. For investigating the effect of different parameters including material length scale, beam thickness, some numerical results on different cross ply laminated beams such as (90,0,90), (0,90,0), (90,90,90) and (0,0,0) are presented on elastic medium. Free vibration analysis of a simply supported beam is considered utilizing the Fourier series. Also, the fundamental frequency is obtained using the principle of Hamilton for four types of cross ply laminations with hinged-hinged boundary conditions and different beam theories. The fundamental frequency for different thin beam theories are investigated by increasing the slenderness ratio and various foundation coefficients. The results prove that the modified couple stress theory increases the natural frequency under the various foundation for free vibration of composite laminated micro beams.

This study compared the pattern of couples' time-use in rural areas. Wives' and husbands' time spent in household work, leisure, and agricultural labor were compared. In addition, this study examined what factors determine the amount of time of couples spent in such activities. According to the results, in general, the pattern of couple's time-use in rural area was different. Regarding the pattern of time-use, three major results could be mentioned. First of all, husband in rural area spent most agricultural labour time in busy farming season. And then husband spent much time in leisure activities and wife spent in household work. Second, wife spent more time in inactive leisure and husband spent more time in active leisure. Third, husband in rural area spent less time in household work. In particular. they spent less time in female-typed work than male-typed work. To examine what factors determine the extent of time spent in such activities, three theories were employed and tested. According to the results, the models employed in this study were realistic in explaining the amount of time of couple in rural area, and more adjustable wife than husband. In conclusion, a combination of the multidimensional theoretical perspectives used in this study helpfully explains the variation in the amount of time-use of couple in rural area.

This study examines the effect of adult-children support network on the psychological well-being of the single and couple elderly households in rural areas. Adult-children support networks include both structural and functional characteristics. For the purpose of this research, 476 participants, who are older than 60 years old, living in rural areas, were selected. The results of this study are summarized as follows: the average degree of psychological well-being of the rural elderly was high. Emotional support from adult children was higher than economic or instrumental support. In the case of the single elderly households, adult children's economic support was the strongest variable affecting the psychological well-being. In the case of the couple elderly households, adult children's emotional support had the greater effect on psychological well-being. On the basis of this analysis, policy implications regarding the single and couple elderly households in rural areas were discussed.

The purpose of this study is to develop a Marriage Enrichment Program that can be applied to the actual lives of Korean families and couples, as well as adopted in family welfare programs. For this study, a quasi-experimental group design was employed and pre- and post- tests on Internal-External Control, Couple Communication, and Marital Satisfaction were conducted. Experimental participants consisted of six volunteer couples who responded to an advertisement by the Chonbuk Family Counseling Center printed in a daily newspaper. The experimental group received two hours of education on marital relationship enhancement every week for eight weeks. The control group received no such treatment. The effectiveness of the education was measured by Wilcox matched pair test, using a SAS program, as well as by the self-report of the participants. The results show that there was statistically significant improvement for the experimental group in all three areas of marriage-- internal control, couple communication, and marital satisfaction. In addition, the participants'evaluations were generally positive about the program. The participants reported that it was most helpful to learn through the educational program that individuals differ in basic needs and that they should not force personal beliefs on others. They also reported that their understanding of their spouse improved.

This study investigated a path model in which men's and women's communication behavior escalating marital conflict (CBEMC) may be influenced directly and indirectly, via negative interpretations of their spouse, by their spouse's problem behavior, the couple's turning toward bids, and dyadic perspective-taking. Self-report data were collected from 498 married men and women who were living in Busan, Korea. Multiple-group analysis revealed that the path model was not equivalent for men and women. Their couple's turning toward bids and dyadic perspective-taking for men, and their spouse's problem behavior and dyadic perspective-taking for women, had direct effects on CBEMC. Further, their spouse's problem behavior and the couple's turning toward bids had indirect effects on CBEMC through negative interpretations in both men and women. The indirect effect of dyadic perspective-taking on CBEMC was significant only for men. Finally, considering total effects, dyadic perspective-taking was the strongest predictor of CBEMC for both genders.

This study aims to identify the change of bathroom design characteristics through the investigation of bathroom space in apartment model houses. The bathroom space of each private exclusive area was analyzed from the plane characteristics perspective such as quantity, location, size and shape. For this study, site survey and observation was performed to analyze the characteristics of plane and design based on twenty seven model houses of seven large-sized construction firms with Seoul area focused on. Research object was restricted to from ten Pyeong's apartment to sixty Pyeong's in order to understand various characteristics of twenty seven model houses. Since analysis variables were not diverse, the main three factors - frequency, percentage and an average - were represented in Microsoft Excel worksheet, focusing on the quantity of each case, design characteristics and pattern. 1) The quantity of bathrooms: It was turned out that the quantity of bathroom was one in ten Pyeong's apartment while it was two in thirty, forty, and fifty Pyeong's apartment. There were mostly two bathrooms available in twenty Pyeong's apartment even if only one was planned in few cases. All powder rooms and dress rooms in twenty and fifty Pyeong's apartment were designed to be separated and be accessible through bedroom. 2) The size of bathrooms: As private exclusive area increased, the size of bathroom for both family and couple increased. Couple bathrooms had the tendency to be equipped with shower booth and bathtub at the same place or have more tubs than family bathrooms because couple bathrooms were bigger than family bathrooms. 3) The location of bathrooms: Couple bathrooms were usually located beyond dress rooms or powder rooms while family bathrooms were mostly located at the entrance side. 4) The shape of bathrooms: Shower booth was assumed to be in general vogue because family bathrooms, for the most part, were comprised of a flush toilet, a washstand and a shower booth. In the case of couple bathrooms, a flush toilet, a washstand, a shower booth and a tub were generally equipped in more than twenty Pyeong's apartments while a tub was not installed in twenty Pyeong's apartments.
