I have empirically investigated the relationship between work-family facilitation and perceived team performance and the moderating effect of wellness climate between work-family facilitation and perceived team performance. For testing hypothesis, hierarchical linear regression was conducted. The results of analysis are followings; hypothesis 1, work-family facilitation is positively related to perceived team performance, was significantly supported. Hypothesis 2, wellness climate moderates the association between work-family facilitation and perceived team performance. The results imply that when the HR practitioners design job and welfare program of employees should consider work-family facilitation. Additionally, to improve the performance of organization should consider not only work-family facilitation but also climate of organization supporting work-family facilitation, wellness climate.

This paper developed a home wellness robot platform to perform the roles in basic health care and life care in an aging society. A robotic platform and a sensory platform were implemented for an indoor wellness service. In the robotic platform, the precise mobility and the dexterous manipulation are not only developed in a symbiotic service-robot, but they also ensure the robot architecture of human friendliness. The mobile robot was made in the agile system, which consists of Omni-wheels. The manipulator was made in the anthropomorphic system to carry out dexterous handwork. In the sensing platform, RF tags and stereo camera were used for self and target localization. They were processed independently and cooperatively for accurate position and posture. The wellness robot platform was integrated in a real-time system. Finally, its good performance was confirmed through live indoor tests for health and life care.

Panax ginseng C. A. Meyer is well known as traditional herbal medicine, and ginseng berries are known to exhibit potential immune-enhancing functions. However, little is known about the in vivo immunomodulatory activity of Korean ginseng berries. In this study, crude Korean ginseng berries polysaccharides (GBP) were isolated and their immunomodulatory activities were investigated using cyclophosphamide (CY)-induced immunosuppressive BALB/c mice. In CY-treated mice, oral administration of GBP (50-500 mg/kg BW) remarkably increased their spleen sizes and spleen indices and activated NK cell activities. GBP also resulted in the proliferation of splenic lymphocytes (coordinating with ConA: plant mitogen which is known to stimulate T-cell or LPS: endotoxin which binds receptor complex in B cells to promote the secretion of pro-inflammatory cytokines) in a dose-dependent manner. In addition, GBP significantly stimulated mRNA expression levels of immune-associated genes including interleukin-1β (IL-1β), IL-2, IL-4, IL-6, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), toll-like receptor 4 (TLR-4), and cyclooxygenase-2 (COX-2) in CY-treated mice. These results indicate that GBP is involved in immune effects against CY-induced immunosuppression. Thus, GBP could be developed as an immunomodulation agent for medicinal or functional food application.

Korean ginseng (Panax ginseng C. A. Meyer), a member of the Araliaceae family, is known as a traditional medicinal plant to have a wide range of health properties. Polysaccharides constitute a major component of Korean ginseng, and its berries exhibit immune-modulating properties. The purpose of this study was to investigate the immune effects of crude polysaccharide (GBPC) extracted from Korean ginseng berry on peritoneal macrophages in mice with cyclophosphamide (CY)- induced immunosuppression. BALB/c mice were divided into eight groups: normal control, normal control + CY, levamisole + CY, ginseng + CY, and four concentrations of 50, 100, 250, and 500 mg/kg BW/day of GBPC + CY. Mice were orally administered with samples for 10 days. Immunosuppression was established by treating mice with CY (80 mg/kg BW/day) through intraperitoneal injection on days 4 to 6. The immune function of peritoneal macrophages was then evaluated. Oral administration of 500 mg/kg BW/day GBPC resulted in proliferation, NO production, and phagocytosis at 100%, 88%, and 91%, respectively, close to the levels of the normal group (100%) of peritoneal macrophages. In CY-treated mice, GBPC of 50-500 mg/kg BW/day also dose-dependently stimulated the proliferation, NO production, and phagocytosis at 56-100%, 47-88%, and 53-91%, respectively, with expression levels of immune-associated genes, such as iNOS, COX-2, IL-1β, IL-6, and TNF-α, of about 0.32 to 2.87-fold, compared to those in the CY group. GBPC could be a potential immunomodulatory material to control peritoneal macrophages under an immunosuppressive condition.

This study was a survey study to provide the base data necessary to prepare efficient management plans for the mothers with disabled children by type, comparing degrees of disability acceptance, stress, coping method and wellness between mothers with physical functional disordered children and developmental disordered children. The study subjects were a mother who raises disordered children. Data collection was conducted from October 2018 to April 2019, and differences between the two groups were analyzed as t-test, ANOVA, and Pearson correlation. In results, Studies have shown that there are differences between the two groups as mothers with physical functional disordered children and mothers with developmental disordered children as degrees of disability acceptance, stress, treatment and wellness. Disability acceptance and coping method of mothers with physical functional disordered children (r=0.23, p=.033), disability acceptance and Wellness (r=0.51, p<.001) have shown positive correlations and disability acceptance and stress (r=-0.72, p<.001) have shown negative correlations. Disability acceptance and wellness (r=0.40, p<.001) of the mother with a developmental disordered child have shown a significant positive correlation, and disability acceptance and stress (r=-0.71, p<.001) have shown a significant negative correlations. The higher the degree of disability acceptance, the lower the stress level and the higher the coping method and wellness mothers with physical functional disordered children had. The higher disability acceptance, the lower stress degrees and the higher wellness degrees mothers with developmental disordered children had. In order to improve disability acceptance by mothers with physical functional disordered children, it was necessary to improve both coping methods and wellness with stress reducing strategy, while the mother with developmental disordered children were needed strategies to reduce stress and improve wellness.

The aim of this paper is to review recent developments and commercialized products in the field of wearable wellness sensors and devices (WWSD). Although there are several dedicated researches, the completed theories and systematic techniques have not been well established. Therefore, we divided the WWSD into four different topics (healthcare, safety & prevention, gaming & lifestyle, and sports & fitness), and review the state of the arts and challenges on the applications on the sensor and device technologies with particular focus on WWSD. We also review the limitations of the current technologies on the developments and commercialized products. Finally, we suggest and discuss new research topics related on the four topics of the WWSD.

This study was conducted to investigate the effectiveness of a nonviolent communication program on nurse's interpersonal competence, job stress and spiritual wellness. This study was a inequality similar to the control group experimental design study of repeated measurements before and after. The data for this study were collected from June 1 to October 20, 2013 from 29 clinical nurses. The self-administered questionnaires used consisted of questions regarding general characteristics, interpersonal competence, job stress and spiritual wellness. The results were: 1. For interpersonal competence, the interaction between time and group was significant (F = 7.726, p = 0.002). 2. For job stress analysis, the interaction between time and group was not significant (F = 0.142, p = 0.851). 3. For spiritual wellness, the interaction between time and group was significant (F = 31.355, p < .001). These results suggest that the nonviolent communication program had a positive effect on rejected clinical nurse's interpersonal competence and spiritual wellness, but not on job stress. A follow-up replication study will be necessary.
