  • Women's nutrition has received little attention in nutrition programming, even though clinical trials and intervention trials have suggested that dietary improvement or supplementation with several nutrients may improve their health, especially in low-income settings, the main focus of this paper. Most attention so far has focused on how improvements in maternal nutrition can improve health outcomes for infants and young children. Adequate vitamin D and calcium nutrition throughout life may reduce the risk of osteoporosis, and calcium supplementation during pregnancy may reduce preeclampsia and low birth weight. To reduce neural tube defects, additional folic acid and possibly vitamin $B_{12}$ need to be provided to non-deficient women before they know they are pregnant. This is best achieved by fortifying a staple food. It is unclear whether maternal vitamin A supplementation will lead to improved health outcomes for mother or child. Iron, iodine and zinc supplementation are widely needed for deficient women. Multimicronutrient supplementation (MMS) in place of the more common iron-folate supplements given in pregnancy in low-income countries may slightly increase birth weight, but its impact on neonatal mortality and other outcomes is unclear. More sustainable alternative approaches deserve greater research attention.

  • Purpose: The purpose of the study was to evaluate the effect of the immediate postoperative nutritional status and calorie adequacy on clinical outcomes in liver transplant recipients. Methods: A total number of 99 patients who received liver transplants were recruited from a tertiary university hospital. Demography, subjective global assessment, clinical outcomes and calorie adequacy were evaluated through personal interviews, electronic medical records and dietary records. Anthropometric measures, body mass index and percent of ideal body weight were also obtained. Results: At admission to the Surgical Intensive Care Unit (SICU), the triceps skinfold thickness and mid-arm muscle circumference were significantly lower in the malnourished group than in the well-nourished group (p<.05, respectively). In the clinical outcomes, transfusion of red blood cells, mechanically ventilated hours, length of stay in the Intensive Care Unit (ICU), length of stay in the hospital, and prothrombin time were significantly higher in the malnourished group than in the well-nourished group (p<.05, respectively). The mechanically ventilated hour was significantly higher in the group with less than 50% of their required energy intake (p<.05). Conclusion: Therefore, it is important to assess the nutritional status of immediate postoperative patients. Furthermore, studies on nutritional interventions are urgently needed to provide adequate nutritional care for patients in ICUs.

  • Purpose: This study was designed to investigate the survey of analyzing nursing interventions and nursing outcomes of the patients with liver transplantation. Method: The subjects of this study consisted of 83 patients and fifteen nurses who took care of them. The methods of this study were retrospective and descriptive survey. Result: The mean age of patients was 42.7 years and the subjects were 62.7% males. 56.7% of these patients were diagnosed with liver cirrhosis of B type. The mean duration of hospitalization was 48.6 days. Ninety-five nursing interventions were performed at least daily. The most frequent used interventions were "environmental management: comfort", "medication administration: parenteral", "cough enhancement", and " oxygen therapy". Even though SGOT level to identify nursing outcomes was decreased, SGOT was not within normal limits. Therefore, even after discharge of patients, There is a need to take care of them carefully. Conclusion: These findings revealed the significance and need of nurse practitioners who performed professional nursing intervention for the patients with liver transplantation. Especially, it is necessary needs to develop the nursing intervention programs for comfort.

  • The objective of this study is to investigate the effects of different meeting modes and task types on the outcomes of group decision making. The hypotheses postulate the potential effects of different meeting modes on appropriation process; different meeting modes on group outcomes; and the appropriation process on group outcomes. A laboratory experiment was conducted. A GSS was developed using Lotus Notes for this experiment. The results provide partial support for the hypotheses derived from the theoretical model. The interaction effects between meeting modes and tasks are not always observed in the analyses. However, groups using a face-to-face meeting mode in negotiation task reach significantly higher levels of perceived outcome quality, of satisfaction with the outcome, and of satisfaction with the process than groups using a dispersed-synchronous meeting mode. It suggests that a face-to-face meeting mode can enhance the effectiveness of groups working on a negotiation task such as stakeholder analysis. Furthermore, the manner in which groups appropriate the technology significantly influence the group performance. The results support the validity and usefulness of the IRT and the AST as a GSS research framework.

  • In order to explore a relationship among KM context, KM effects, and sustainability of competitive advantage of organizations, a contingency model of KM, which is based on resource-based as well as knowledge-based theory, is developed from the information systems and strategic management literature. To put it concretely, our motivation for this paper was to answer the following questions: (1) What factors affect the degree to which an organization achieves KM effects? (2) Is there a positive relationship between KM effects and organizational performance achieved by linking KM to competitive advantage? A detailed exploratory analysis of survey responses from 79 Korean companies provides the following significant findings: (1) This study found support for the proposed research model. (2) The organization's degree of process and organizational outcomes of KM effects is determined by technical and social resources and its capabilities. Furthermore, the influence of technical and social resources of KM context on process and organizational outcomes of KM effects is controlled by different types of organizational perspectives on KM. (3) There is a relationship between process and organizational outcomes of KM effects and organizational performance enhanced by linking KM to competitive advantage.

  • With the rapid development of information technology, e-learning is growing in corporate. However, there are still problems in learning, such as low learning persistence rate. Learning outcomes are complex phenomenon influenced by a multitude of factors, it is need to considering the direct and indirect causal relationship among various factors. Therefore, the purpose of this study was to develop the causal model that explains the learning outcomes (satisfaction learning persistence) in corporate e-learning. This study was also intended to examine the causal relationship between the interaction and learning persistence through satisfaction mediators. For this, online survey was conducted with a sample of 270 learners who enrolled in cyber training course at A company. The major findings of this study are as follows: First, internality (internal locus of control, ${\beta}=.154$), interaction (${\beta}=.489$), satisfaction (${\beta}=.304$) have direct effect on learning persistence. Second, the interaction has direct effect on the satisfaction (${\beta}=.320$). Third, the satisfaction has direct effect on the learning persistence, and mediating the interaction and learning persistence. This result will contribute to build a learning strategy to improve learning outcomes.
