Negative experience related to work-family multiple roles has been associated with internalizing problems in mothers. In particular, employed mothers with preschool children report high degree of stress. As such, the need to examine potential factors that may explain and alleviate such difficulties has been emphasized. The purpose of this study was thus to examine the mediating effect of sociotropy on the relationship between negative work-family multiple roles and internalizing problems in employed mothers with preschool children. The Negative Experience of Work-Family Multiple Roles Scale, Adult Self Report (ASR) Scale, and Personal Style Inventory-II (PSI-II), were completed by 208 employed mothers with preschool children through an online survey. The results indicated that the direct effect of negative experience of work-family multiple roles on internalizing problems was statistically significant and the indirect effect of sociotropy in this relationship was significant. These findings suggest that sociotropy in employed mothers may indirectly explain internalizing problems related to multiple roles. The implications of sociotropy in negative experience of work-family multiple roles and internalizing problems are discussed.

In this paper, 1 examined role gratification and role strain of South Korean working mothers. The results show that South Korean working mothers experienced very similar level of role gratification and role strain as taking their multiple roles. The findings also show that the factors of caregiving demands, employment demands, caregiving resources, employment resources are not strongly related to role gratification and role strain. Among the 12 caregiving demand variables and employment demand variables, number of children, type of family, number of hours worked were significantly related to producing role gratification. Among the 12 caregiving demand variables, number of hours worked, number of husbands absence due to night work were significantly related to producing role strain. Among the 8 caregiving resources, participants satisfaction due to income contribution, look to make a purchase new electric home appliances were significantly related to produce role satisfaction. Among the 8 caregiving resources, number of family support policies in the husbands workplace, participants satisfaction due to income contribution were significantly related to producing role strain.

The purpose of this study is to investigate the influence of family-friendly life environment factors including local community's living environment satisfaction (safety, convenience, comfort, accessibility, exchange of neighbor satisfaction), family support facility satisfaction, family support program satisfaction and nurture and education environment satisfaction, and local community's living information accessibility on the effect of multiple roles of married men and women with children. Data were collected from 380 married men and women with children located Seoul, GyeongGi-Do, ChungCheongBuk-Do, and KyungSangNam-Do. The results show that, first of all, related to general trend of role satisfaction and role strain, the subjects have higher experience of role satisfaction than role strain. Secondly, the variables of social demography, such as monthly income, non-regular full-time working system, white collar occupation, number of children and level of education, and living environment variables, such as satisfaction of living environment stability and satisfaction of neighbor exchange in living environment were significantly related to role strain. Thirdly, social demography variables, such as average monthly earnings, gender (male), non-regular part-time working system, satisfaction of stability in living environment, and satisfaction of convenience in living environment were significantly related to role strain.

The aim of the present study is to test multiple mediating effects of job-efficacy and resiliance in the links between work-life balance (WLB) and deviant behavior. The date applied in empirical analysis was collected from employees working at Jeju island and 400 sets of questionnaires were spread and among collected 355 sets, 298 sets were used. Hypotheses was examined with SPSS Macro statistical package. As expected, WLB was positively related to job-efficacy and resiliance respectively and negatively associated with deviant behaivor. Moreover, mediating effects of both variables was different, in detail, job-efficacy was fully mediated in that path but not significant in case of resiliance. Findings of this study was to expand the roles of WLB from productive behaviors to counter-productive behaviors and it enables to provide a few theoretical and empirical implications.

해안지역에서 염수침입을 저감하기 위한 지하댐은 전세계적으로 많이 사용되고 있으며, 일반적으로 염수를 포함하고 있는 지하수의 이동을 차단하는 역할을 한다. 이러한 차단으로 인해 지하댐 내 바다 방향으로 향해있는 영역과 해안 내륙에서의 오염물질과 염분의 축적이 발생될 수 있다. 기존의 염수칩입을 저감하기 위해 이용되는 지하댐의 연구는 대부분 불투수성으로 고려하여 수행되었으나 본 연구에서는 투수성 다공성 지하댐에 대한 효과를 수치적 기법을 이용하여 분석하였다. 이러한 투수성 다공성 지하댐은 해수위의 변화에 따라 염수와 담수의 흐름을 원활하게 할 수 있으며, 이로 인해 오염물질과 염분의 축적이 최소화 될 수 있을 것으로 기대할 수 있다. 본 연구에서는 상용 유동모의 및 해석 소프트웨인 ANSYS CFX 모형을 이용하여 투수성 다공성 지하댐의 유효높이와 유효폭 그리고 단일 그리고 다중 양수에 따른 염수침입의 특성을 분석하였으며, 이에 대한 지하댐의 최적 위치에 대한 분석을 수행하였다.

Multilayered structures include lamination by relatively thick plies and thin interlayers. For efficient peridynamic analysis of dynamic fracturing multilayered structures, the interlayer is modeled using ghost peridynamic particles while the ply is formulated via real peridynamics. With the nonlocal ghost interlayer, one may keep the discretization resolution low for the ply. In this study, the characteristics of dynamic wave propagation through the nonlocal ghost interlayer in peridynamic analysis are investigated. It is observed that the interlayer not only binds adjacent plies, but also significantly influences energy transfer between plies, and thereby their deformation and motion. In addition, near a surface or boundary, peridynamic particles do not have a full nonlocal neighborhoods. This causes the effective material properties near the surface to be different from those in the bulk. Surface correction based on neighborhood volumes is employed. The impact of surface correction on wave propagation in multilayered structures is investigated.

다자간 데이터 송수신을 필요로 하는 다자간 화상 회의, 일대다 스트리밍, 일대다 파일 전송 등의 응용에서는 멀티캐스트를 사용하여 데이터 전송 부담을 줄일 수 있다. 그러나 IP 멀티캐스트가 인터넷 상에서 널리 지원되지 않고 있기 때문에, 멀티캐스트를 응용 계층에 구현하려는 연구가 활발히 진행되고 있다. 본 논문에서는 일대다 대용량 파일 전송에서 효과적으로 전송시간을 단축할 수 있는 응용계층 멀티캐스트 기법을 제시한다. 신뢰적 전송을 위하여 Forward Error Correction (FEC)를 사용하여, 전송시간 단축을 위해 데이터 소스 외에 수신자들이 가상적으로 소스의 역할을 수행하도록 한다. 즉, 임의의 수신자는 데이터 소스뿐만 아니라, 다중 가상 소스로부터도 데이터를 수신할 수 있으므로 파일 수신 시간을 단축시킬 수 있다.

본 연구에서는 딥 러닝을 이용하여 완전 자동화된 다중 클래스 전체 심장 분할 알고리즘을 제안하였다. 제안된 방법은 recurrent convolutional block과 residual multi-dilated block을 삽입하여 기존 U-Net을 개선한 인공신경망 모델을 사용하였다. 평가는 자동화 분석 결과와 수동 평가를 비교하였다. 그 결과 96.88%의 평균 DSC, 95.60%의 정확도, 97.00%의 recall을 얻었다. 이 실험 결과는 제안된 방법이 다양한 심장 구조에서 효과적으로 구분되어 수행되었음을 알 수 있다. 본 연구에서 제안된 알고리즘이 의사와 방사선 의사가 영상을 판독하거나 임상 결정을 내리는데 보조적 역할을 할 것을 기대한다.
