The purpose of this study was to determine the relationship between children's dietary self-efficacy, general characteristics and mother's parenting self-efficacy among elementary school students. Mother's parenting self-efficacy was significantly higher as parents' educational levels increased (p<0.001), as family monthly income level increased (p<0.001), and when father's job was professional or managing work (p<0.001). Children's dietary self-efficacy was meaningfully higher when parents' educational levels were higher (p<0.01), and family income level was higher (p<0.01). Mother's parenting self-efficacy showed a correlation with children's dietary self-efficacy (p<0.001). All factors comprising parenting self-efficacy, such as 'general parenting self-efficacy' (p<0.001), 'healthy parenting self-efficacy' (p<0.001), 'communication parenting self-efficacy' (p<0.001), 'educational parenting self-efficacy' (p<0.001), and 'control parenting self-efficacy' (p<0.001) showed correlation with children's dietary self-efficacy. It is suggested that in order to improve children's dietary self-efficacy and mothers' parenting self-efficacy, families, schools, and communities must put forth a concerted effort. By complementing existing nutritional programs focusing on nutritional knowledge, one can develop a education program and social support to enhance children's dietary self-efficacy and mothers' parenting self-efficacy.

Purpose: The aims of this study were to describe the levels of personal coping resources, perceived organizational supports, and job stress, and to examine factors that affect job stress in hospital-based home care nurse practitioners. Methods: A cross-sectional survey was conducted. Data were collected from 170 subjects with a structured questionnaire from April to July, 2016 and analyzed using descriptive statistics, t-tests, One-way ANOVA, Pearson's correlation, and multiple regressions. Results: The means for personal coping resources, perceived organizational supports, and job stress were $3.7{\pm}0.43$, $3.4{\pm}0.55$, and $3.4{\pm}0.55$ out of 5, respectively. Personal coping resources and perceived organizational supports were significantly correlated. However, both had no associations with job stress. In the multiple regression analysis, the experiences of home care nursing and hospital location were found to be predictors of job stress. Both personal coping resources and perceived organizational supports were not statistically significant predictors of job stress. Conclusions: It is necessary to carry out organization-based educational programs and support systems aimed at enhancing personal abilities to cope with stress at work. Additionally, further studies are needed to identify other hospital-related characteristics that can lead to job stress in home care nurse practitioners.

Purpose: The study was aimed at qualitatively enhancing and promoting a home visiting nursing program established in Korea on July 1, 2008, as part of the Long-Term Care Insurance for the Elderly program. Methods: Structural, procedural and consequential aspects of home visiting nursing care wereclassified on the horizontal axis by applying the standard notions for the evaluation of medical care (Donabedian, 1998). At the same time, the home visiting nursing care service support system and the service provision system weredivided on the vertical axis with reference to the accreditation standards for home visiting nursing care organizations suggested by the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO, 2008). The data were collected from June 4, 2008 to October 27, 2008, and were analyzed using SPSS ver. 15.0. Results: Twenty-two (proposed) standards, centered on the standard elements under the conceptual framework of the study, were developed, and comprised structural aspects (n=10), procedural aspects (n=6) and consequential aspects (n=6). Those criteria and indicators underwent two content validity surveys among groups of home visiting nursing care research and training experts. The research produced 22 proposed standards, 50 proposed criteria and 166 proposed indicators. Conclusion: The home visiting nursing care standards developed pursuant to the Long-Term Care Insurance for the Elderly Act and the applicability of these standards need to be verified by home visiting nurses. These proposed standards should prove useful in developing an assessment tool to encourage the qualitative enhancement of visiting nursing care in Korea.

In order to support efficiently the multimedia applications, such as virtual classroom, video conferencing and tele-medical, the efficient multipoint-to-multipoint(MP-to-MP) connection management function is essential. Shared tree is reported as the most useful method for this purpose. In this paper we propose a new MP-to-MP connection setup & management scheme, called CIMA(Cell Interleaved Multiplexing on ATM) scheme,which is a VC merging method for MP-to-MP communication using shared tree. In the CIMA scheme,MRM cell delivers the cell merging information to the next node. The receiving node can identfy cells which arrived through a channel using the same VPI/VCI by the merging information in the MRM cell. Therefore the CIMA scheme can solve easily the Cell Interleaving Problem(CIP) that happens in VC merging. We analyzed the overhead of the proposed CIMA by mathematical analysis,and simulated the buffer usage of CIMA with OPNET. As the result of analysis,we found that the CIMA scheme has acceptable merging overhead and doesn't cause the buffer scare problem.

The trophectoderm is one of the earliest cell types to differentiate in the forming placenta. It is an important for the initial implantation and placentation during pregnancy. Trophoblast stem cells (TBSCs) develop from the blastocyst and are maintained by signals emanating from the inner cell mass. However, several limitations including rarity and difficulty in isolation of trophoblast stem cells derived from blastocyst still exist. To establish a model for trophoblast differentiation, we isolated TBSCs from human term placenta ($\geq$38 weeks) and characterized. Cell cycle was analyzed by measuring DNA content by FACS analysis and phenotype of TBSCs was characterized by RT-PCR and FACS analysis. TBSCs have expressed various markers such as self-renewal markers (Nanog, Sox2), three germ layer markers (hNF68, alpha-cardiac actin, hAFP), trophoblast specific markers (CDX-2, CK7, HLA-G), and TERT gene. In FACS analysis, TBSCs isolated from term placenta showed that the majority of cells expressed CD13, CD44, CD90, CD95, CD105, HLA-ABC, cytokeratin 7, and HLA-G. Testing for CD31, CD34, CD45, CD71, vimentin and HLA-DR were negative. TBSCs were shown to decrease the growth rate when cultured in conditioned medium without FGF4/heparin as well as the morphology was changed to a characteristic giant cell with a large cytoplasm and nucleus. In invasion assay, TBSCs isolated from term placenta showed invasion activities in in vivo using nude mice and in vitro Matrigel system. Taken together, these results support that an isolation potential of TBSCs from term placenta as well as a good source for understanding of the infertility mechanism.

This study was conducted to identify families' perception and attitude toward application of physical restraint(PR) in general neurological wards. The study is based on subjects from 70 family members who have cared patients applying PR. Data was collected using self-report questionnaires and reviewing of patients' medical records. 68.6% of subjects were female and the mean age was 47.9 years old. Family members were either sons, daughters or spouses. The questionnaires analyzed families' perceptions based on a score of 5, the results showed a mean score of 4.2, and items related to maintaining therapeutic tools scored the highest. The application of PR with two hands was perceived by families as more important than PR applied with one hand. In families' attitude toward PR, there was general agreement that families had the right to decide to apply and remove PR. Continuous education and information regarding PR is required to support families.
