Purpose : This systematic review was conducted to identify which dyadic intervention could be implemented for heart failure patient-family caregiver dyads to improve patient and/or their family caregivers outcomes. Method : Eleven databases were searched from their inception to July, 2021. This review considered any randomized controlled trials that evaluated the effectiveness of intervention including heart failure patient-family caregiver dyads. Two reviewers independently evaluated the methodological quality using the Cochrane Collaboration's tool for assessing risk of bias and extracted details of the included studies. The studies included in this review were not suitable for meta-analysis and therefore the results were presented as a narrative summary. Results : Six studies including 900 dyads were included and mainly primary family caregiver of patients was spouse. Majority of dyadic intervention were focused on psychoeducational intervention excepting one study on mobile health intervention. All studies included in this review focused on patients' outcomes compared to family caregivers' outcomes and dyadic outcomes. Individual interventions improved quality of life among heart failure patients and their family caregivers in two articles. The overall quality of selected articles was low. Conclusions : This study provides moderate support for the use of a dyadic intervention to improve quality of life among heart failure patients and their family caregivers. More rigorous high-quality studies investigating interventions to meet the needs of patient and family caregivers in heart failure care are needed.

본 연구는 노년기 부부의 남편과 아내가 경험하는 부부관계 만족과 우울이 시간에 따라 어떻게 변화하는지를 모형화하고, 부부관계 만족의 변화가 우울의 변화를 어떻게 설명하는지를 확인하였다. 분석에는 한국고용정보원에서 수집하는 고령화연구패널조사(KLoSA)의 1차(2006)부터 5차(2014)까지의 종단 짝 자료가 사용되었다. 본 연구는 남편과 아내의 상호의존성을 고려하여 '부부'를 분석 단위로 하는 통계모형을 적용하였다. 부부관계 만족과 우울의 변화 궤적에 대한 분석에는 이자성장모형(DGM)이 사용되었다. 이 변화 궤적들 사이의 상호의존적 관련성을 분석하기 위해서 이자성장 행위자-상대방 상호의존 모형(DG-APIM)을 제안하고 이를 적용하였다. 분석결과 조사 기간 동안의 부부관계 만족의 평균은 남편이 아내에 비해 더 높았지만 관계 만족의 감소율도 더 높았다. 또한 남편의 우울은 아내에 비해 평균적으로 더 낮았지만 시간에 따라 더 크게 증가하였다. 남편과 아내의 우울 평균 수준은 배우자의 부부관계 만족의 평균 수준에 의해 설명되는 상대방 효과를 보였으며, 우울의 변화율의 크기는 자신의 관계 만족의 변화율의 크기에 의해 설명되는 자기효과를 보였다. 이러한 결과는 남편과 아내의 부부관계만족도와 우울 사이에 종단적 상호의존성이 존재한다는 것과 우울의 결혼 불화 모형이 종단적 변화에서도 지지된다는 것을 보여준다.

The study aims to investigate new theoretical approaches in an effort to resolve conceptual contradictions regarding the impact of organizational culture on developing culture for change, first by providing socio-structural frameworks supporting intrapreneurship, and second through encouraging professional culture behavior with management practices or organizational members acting as agents of change forming a deeper culture of values and behavior. The design of this research is quantitative. This study employs survey data of managers and section heads, which met the sampling requirements. Data analysis in this research used structural equation modeling (SEM) with the help of the AMOS program. The results show that all hypotheses are supported. The findings of this study suggest that the organizational culture transformation and dyadic social intrapreneurship based on professional culture (DSIBPC) have significant positive influence as antecedents of competitive advantage. This research also shows that DSIBPC is able to act as an important mediator that fills a gap in the relationship between organizational culture transformation toward competitive advantage, as well as being an alternative strategy for organizations in an effort to increase their competitive advantage. Referring to the results of this research, organizations need to focus and pay attention to the DSIBPC.

The main purpose of this article was to examine the general tendency of self-disclosure and perceived self-disclosure in married couples, and to study the effect of demographic variables on them. and to find out how dyadic trust affects on self-disclosure in married couples. Considering those purposes, the following research questions have been raised : 1) What is the general tendency of self-disclosure in married couples? 2) What is the general tendency of perceived self-disclosure in married couples? 3) Does perceived self-disclosure affect on self-disclosure in married couples? 4) How do the demographic varibles affect on self-disclosure in married couples? 5) Does dyadic trust affect on self-disclosure in married couples? To solve these questions, a questionnaires which consisted of 8 items for demographic variables, of which 8 questions are for dyadic trust, and 36 questions for self-disclosure in married couples was made. This reserch 몽 been conducted from April 4, 1990 to April 15, 1990. which surveyed 560 married men and women who are living in Seoul. Only answers from 432 married men and women were analysed out of them. The analytic methods adopted in this study were the frequency, the perentage, t-test, oneway ANOVA, DUNCAN -tst, and pearson's r. Especially SPSS/${pc}^+$ program was used in order to promate the feasibility in statistical analysis. The major findings of the study are as follows : 1) Self-disclosure in married couples in generally higher than expected(M=40.4) : wife's self-disclosure(M41.5) is higher than husband's self-disclosure(M=39.4) 2) Between self-disclosure and perceived self-disclosure in married couples correlated considerably high(husband r=0.67, wife r=.75) 3) Self-disclosure in married couples are affected by the variables such as age, length of marriage, everage family income a month. 4) Self-disclosure in married couples correlated relatively low with dyadic trust(husband r=0.21, wife r=.31)

Purpose: The purpose of this study was to explore recognition of mother-child interaction by preschoolers' mothers. Methods: Data were collected through in-depth interviews with mothers of 12 preschoolers. The data were analyzed following Downe-Wamboldt's content analysis methodology. Results: From the data, 170 significant statements were selected and were classified into 7 categories and three domains (maternal, child, dyadic). First, the maternal domain consisted of maternal sensitivity, acceptable responsiveness, and child developmental encouragement. Second, the child domain consisted of child's sensitivity, responsiveness, and initiative. Third, the dyadic domain consisted of mutuality. Conclusion: These results suggest that preschoolers' mothers recognize the significant qualitative aspects of interaction with their children. Based on these results, instruments for preschooler-mother interaction need to be developed.

For GPR(Ground Penetrating Radar) applications, an accurate analysis of the scattered field is necessary to identify the unknown target. Dyadic Green's function of the multilayered medium is developed and applied to analysis of the underground conducting object. We used method of moment(MOM) with dyadic Green's function, and Discrete Complex Image Method(DCIM). To reduce the computational complexity, fast multipole method is introduced and we showed the accuracy of the method comparing with the conventional method of moment. For investigating the underground conducting target, several numerical experiments were accomplished using this method.

This study showed that the association between solidarity and conflict is mediated by the communication of grandmothers and an adult child at the dyadic level. The common fate model (CFM) was designed to model mediation effects at the level of dyads. Participants consisted of 297 grandmother dyads and their adult child who were rearing preschool-aged grandchildren in Seoul and Gyeonggi-do. For analysis at the dyadic level, grandmothers and adults responded to the same questionnaire on the same variables. SPSS 23.0 performed descriptive statistical analysis and correlation analysis. The structural equation model (SEM) was estimated with AMOS 23.0. We tested the mediation model using the maximum likelihood method. Model fit index used the chi-square statistic, the incremental fit index (IFI), the comparative fit index (CFI), the root mean square error of approximation (RMSEA). The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, in the CFM, the direct effect between solidarity and conflict was significant. Therefore, the higher the solidarity, the lower conflict of grandmothers and an adult child. Second, the association between solidarity and conflict is mediated by communication at the dyadic level. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandmothers and an adult child.
