This study aims to determine whether employment status moderates and mediates the effect of parenting stress on parenting efficacy through mental health and hope targeting women raising children and to find ways to improve parenting efficacy by utilizing mental health and hope. The survey was conducted nationwide, a purposive sampling method was used to select the survey subjects, and data were collected through a survey. The total number of subjects used in the final analysis was 300 women. Data were analyzed by applying frequency analysis, reliability analysis, correlation analysis, and moderated mediation effect analysis. The results of the study are as follows. First, as a result of correlation analysis, parenting stress showed a negative correlation with mental health, hope, employment status, and parenting efficacy. On the other hand, other variables except parenting stress showed positive correlations with each other. Second, employment status moderated and mediated the effect of parenting stress on parenting efficacy through mental health and hope. In other words, employment status played a buffering role in reducing the negative impact of parenting stress on parenting efficacy through mental health and hope. Based on these results, a plan to protect parenting efficacy was proposed.

This paper describes a test case generation algorithm for Simulink/Stateflow models based on the Rapidly exploring Random Tree (RRT) algorithm that has been successfully applied to path finding. An important factor influencing the performance of the RRT algorithm is the metric used for calculating the distance between the nodes in the RRT space. Since a test case for a Simulink/Stateflow (SL/SF) model is an input sequence to check a specific condition (called a test target in this paper) at a specific status of the model, it is necessary to drive the model to the status before checking the condition. A status maps to a node of the RRT. It is usually necessary to check various conditions at a specific status. For example, when the specific status represents an SL/SF model state from which multiple transitions are made, we must check multiple conditions to measure the transition coverage. We propose a unique distance calculation metric, based on the observation that the test targets are gathered around some specific status such as an SL/SF state, named key nodes in this paper. The proposed metric increases the probability that an RRT is extended from key nodes by imposing penalties to non-key nodes. A test case generation algorithm utilizing the proposed metric is proposed. Three models of Electrical Control Units (ECUs) embedded in a commercial vehicle are used for the performance evaluation. The performances are evaluated in terms of penalties and compared with those of the algorithm using a typical RRT algorithm.

In the last decade, rapid developments in molecular biotechnology and of genomic tools have enabled the creation of dense linkage maps across whole genomes of human, plant and animals. Successful development and implementation of interval mapping methodologies have allowed detection of the quantitative trait loci (QTL) responsible for economically important traits in experimental and commercial livestock populations. The candidate gene approach can be used in any general population with the availability of a large resource of candidate genes from the human or rodent genomes using comparative maps, and the validated candidate genes can be directly applied to commercial breeds. For the QTL detected from primary genome scans, two incipient fine mapping approaches are applied by generating new recombinants over several generations or utilizing historical recombinants with identity-by-descent (IBD) and linkage disequilibrium (LD) mapping. The high resolution definition of QTL position from fine mapping will allow the more efficient implementation of breeding programs such as marker-assisted selection (MAS) or marker-assisted introgression (MAI), and will provide a route toward cloning the QTL.

Objectives: The purpose of this article was to investigate the current status of clinical studies of acupuncture treatment for depression using neuroimaging method, focusing on SCI papers. Methods: We searched for clinical trial studies of acupuncture treatment for depression using neuroimaging method in the MEDLINE (Pubmed), OASIS, and RISS database. Once the online search was finished, studies were selected manually by the inclusion criteria. Finally, we analyzed the characteristics of selected articles and reviewed the neural substrates of acupuncture treatment in depression. Results: Total eight studies were included in this study. The most frequently utilized modality was functional MRI. The most frequently selected acupoint for depression was GV20. Several studies revealed that acupuncture treatment could improve the symptoms of depression. In this manuscript, we demonstrated that neuroimaging techniques could capture the neural substrates associated with depression and acupuncture treatment may modulate the activation of brain areas which were impaired in depression in a different way from sham acupuncture. Conclusions: Utilizing neuroimaging methods to explore neural mechanism of acupuncture treatment on depression would be helpful in clinical trials and more efforts should be needed in this fields.

Three benefits of incorporating writing in engineering curricula are presented. The first benefit is in improving the communication skills which are essential for engineers and are attained through practice. The second benefit is in enhancing learning and is achieved by utilizing the complex process of writing to heighten the level of understanding. The third benefit, though difficult to recognize and even more difficult to promote in a society (and educational institutes) steeped in the behaviorist tradition, is in promoting meaningful learning by cultivating motivation internal to students themselves. The boundaries of writing activities are broadened to include that of stating a paragraph or even one complete sentence such that it may be incorporated in engineering without undue strain. A two-year trial of incorporating four types of writing assignments in six different courses (a total of 12 classes) at Michigan Technological University shows that writing assignments can be designed to achieve different degrees of the three aforementioned benefits. It is found that different types of writing activities need to be assigned depending on the status of course (elective vs. required) and on the composition of the students taking the course (upper division vs. lower division; majors vs. non-majors).

The meanings of colors vary with time and space. For the most important events in a person's life, such as wedding or funeral, people use color to symbolize their identities or roles. Traditionally, the colors of dress had indicated the wearer's age, class, or marital status in Korea. However, Korea's exposure to western cultures has affected in many dimensions of its modern history. Especially, influenced by social change, the traditional dress has undergone many modifications in forms, silhouettes, materials, and color. However, women's mourning dress has been maintained as a long lasting tradition and the use of white in mourning dress has been regarded as a norm until recently, while men have worn a regular black suit with a black tie. But, the shift from white to black in mourning dress has been observed in recent mourning practices. To examine this change of color in Korean traditional mourning dress, a historical approach utilizing multiple resources, such as interview, observations of events, documents, and archival records was applied.
