Purpose: The purpose of this study was to explore preserved belief system supporting Korean immigrant women's Taekyo practices and influencing factors while they observe the tradition within US sociocultural context. Methods: Leininger's exploratory focused ethnographic approach was used. Semi-structured in-depth interviews were conducted with purposive sample of sixteen Korean immigrant women who gave birth in the US within last 6 months. Researcher's observation and reflective field notes were also integrated into the interview data. Leininger and McFarland's four phases of ethnographic analysis guided data analysis process. Results: The perceived belief system supporting Taekyo practices included Taekyo as an enculturated Korean tradition, connecting parents with fetus, and positive impacts on fetal development. And Korean immigrant women's Taekyo practices were influenced by resources of information, woman's orientation toward Taekyo, pressure from local Korean community, and child order. Conclusion: The findings from this research would serve as an important knowledge base to expand US health care providers' understanding of Korean traditional Taekyo practices observed by Korean immigrant women's as important prenatal self-care practices. The findings could also aid in providing more patient-centered and culturally-tailored prenatal care plan to Korean immigrant by including Korean traditional belief system supporting Taekyo practices.

Purpose: This study was done to develop and test a palliative care program based on home care nursing. Methods: A quasi-experimental design was employed. Changes in the variables were evaluated to test effects of the developed program. Participants were patients with terminal cancer and their families receiving home care nursing from six hospitals (experimental group: 24 and control group: 22). Data collection was conducted from February to October, 2006. Chi-square test, Fisher's exact test, t-test, Mann-Whitney U test and repeated measures ANOVA were used to analyse the data. Results: Hypothesis 1, the experimental group receiving this program will experience less pain (severe, average, weak pain) than the control group, was supported. Hypothesis 2, the experimental group will have less symptom experience than the control group, was supported. Hypothesis 3, the experimental group will have higher QOL than the control group, was supported and the last hypothesis 4, family burden in the experimental group will be less than the control group, was supported. Conclusion: The home care nursing based palliative program developed in this study was found to be an effective program to reduce patient pain and symptom experience, to improve patient QOL and to decrease family burden.

Purpose: The purpose of this study was to investigate the nutritional support, gastric residual volume, and nutritional status of the intensive care unit (ICU) patients on enteral feeding. Methods: A descriptive longitudinal design was used to collect 5 day data on enteral nutrition of 52 ICU patients in an university hospital. Nutritional support was calculated with actual caloric intake compared to individual caloric requirement. Residual volumes were measured prior to routine feedings, and the serum albumin levels and the total lymphocyte counts were checked to evaluate nutritional status. The data were analyzed using one group repeated measures ANOVA, paired t-test, and Spearman's bivariate correlation analysis. Results: The subjects received their first enteral feeding on the $5.75^{th}$ day of ICU admission. The mean nutritional support rate was 49.1% of the requirement, however prescription rate and support rate were increased as time goes by. Gastric residual volumes were less than 10 cc in 95% cases. A significant negative correlation was found between nutritional support and nutritional status. Conclusion: The nutritional support for ICU patient was low compared to the requirement, and their nutritional status was worse than at the time of ICU admission. Further studies are necessary to develop nursing interventions for improving nutritional support for ICU patients.

Purpose: This study was conducted to analyze intubation survival rates according to characteristics and to identify the risk factors affecting deliberate self-extubation. Methods: Data were collected from patients' electronic medical reports from one hospital in B city. Participants were 450 patients with endotracheal intubation being treated in intensive care units. The collected data were analyzed using Kaplan-Meier estimation, Log rank test, and Cox's proportional hazards model. Results: Over 15 months thirty-two (7.1%) of the 450 intubation patients intentionally extubated themselves. The patients who had experienced high level of consciousness, agitation. use of sedative, application of restraints, and day and night shift had significantly lower intubation survival rates. Risk factors for deliberate self-extubation were age (60 years and over), unit (neurological intensive care), level of consciousness (higher), agitation, application of restraints, shift (night), and nurse-to-patient ratio (one nurse caring for two or more patients). Conclusion: Appropriate use of sedative drugs, effective treatment to reduce agitation, sufficient nurse-to-patient ratio, and no restraints for patients should be the focus to diminish the number of deliberate self-extubations.

This study was done to Identify the relations between psychosocial factors and symptoms of patient with rheumatoid arthritis. Its subjects were 150 outpatients selected at H. Rheumatism clinic from July to August in 1998. Data were collected by means of questionnaires using interview. Those data were analyzed by Frequency, t-test, ANOVA, pearson's correlation using SPSS window 8.0. The results were as follows : 1) The level of family support was relatively high and the level of self-efficacy and performance of daily living activities were average. Among their symptoms, fatigue and pain were frequent problems. 2) Family support was different by educational level, self-efficacy and physical, psychological symptoms were different by performance of regular exercise. 3) The family support was inversely related to physical symptoms especially ADL, while it was not related to psychological symptoms except a reverse correlation between depression and anxiety, and family support. Self-efficacy held a reverse correlation with both physical and psychological symptoms. And there was a close relationship between symptoms. In conclusion it was found that the promotion of family support, self-efficacy and exercise-performance holds a key post in reducing symptoms of rheumatoid arthritis.

Purpose: This retrospective study was designed to examine the frequency of unplanned extubation, and to identify the related factors of unplanned extubation in medical intensive care unit patients. Methods: Data were collected from medical records of patients who received intubation in a medical intensive care unit. One hundred eighteen patient charts were selected for the study. The Patient Severity Classification Scale and unplanned extubation risk factors were examined. Data were analyzed with descriptive statistics, $x^2$-test, Fisher's exact test and Mann-Whitney U test. Results: The incidence of unplanned extubation was 11 (9.32%) out of 118 patients who had undergone intubation. There were statistically significant differences between the unplanned extubation and work shift ($x^2$=61.52, p=.001), ventilation mode (p=.001), number of days of ventilator application (U=366.00, p=.038) and administration of sedatives (p=.025). Conclusion: Unplanned extubation is affected by the following variables: a) whether a nurse is in night shift, b) whether ventilation is mandatory, c) duration of ventilation use and d) administration of sedatives.

Electrocardiogram (ECG) signal gives a clear indication whether the heart is at a healthy status or not as the early notification of a cardiac problem in the heart could save the patient's life. Several methods were launched to clarify how to diagnose the abnormality over the ECG signal waves. However, some of them face the problem of lack of accuracy at diagnosis phase of their work. In this research, we present an accurate and successive method for the diagnosis of abnormality through Discrete Wavelet Transform (DWT), QRS complex detection and Support Vector Machines (SVM) classification with overall accuracy rate 95.26%. DWT Refers to sampling any kind of discrete wavelet transform, while SVM is known as a model with related learning algorithm, which is based on supervised learning that perform regression analysis and classification over the data sample. We have tested the ECG signals for 10 patients from different file formats collected from PhysioNet database to observe accuracy level for each patient who needs ECG data to be processed. The results will be presented, in terms of accuracy that ranged from 92.1% to 97.6% and diagnosis status that is classified as either normal or abnormal factors.

A novel approach for electrocardiogram (ECG) analysis within a functional sensor node has been developed and evaluated. The main aim is to reduce data collision, traffic overload and power consumption in healthcare applications of wireless sensor networks(WSN). The sensor node attached on the patient's body surface around the heart can perform ECG analysis based on a QRS detection algorithm to detect abnormal condition of the patient. Data transfer is activated only after detected abnormality in the ECG. This system can reduce packet loss during transmission by reducing traffic overload. In addition, it saves power supply energy leading to more reliable, cheap and user-friendly operation in the WSN for ubiquitous health monitoring.
