The aim of this study is to determine if intra-bursal morphine and Bupivacaine mixed infusion provided useful analgesia after subacromial arthroscopic operation. At the end of the subacromial arthroscopy, continuous intra-bursal infusion catheter was inserted. In a double-blind randomized trial, Sixty patients were allocated to one of two groups: placebo group(n=30) received continuous saline infusion. Study group received mixed 5㎖ of 0.5% Bupivacaine, 2㎎ of morphine and 0.05㎖ of 1/1000 epinephrine as bolus and mixed solution of 40㎖ of 0.5% Bupivacaine and 8㎎ of morphine as maintenance dose with continuous infusion pump(0.5㎖ hourly). In the placebo group, two patients were discontinued due to leakage and catheter coming out each. Intensity of pain was evaluated preoperatively and postoperatively for 3 days by 10 graded visual analogue scale. Night pain, pain on motion, sleep disturbance, lying on painful shoulder and amounts of intramuscular pain killer were recorded. Analgesic effect for pain was cleared at 1st and 2nd postoperative day and there was less sleep disturbance for 3 days postoperatively in study group. There was no difference in pain on motion postoperatively. In study group, less pain killers were used in the first 48 hours postoperatively. The continuous intra-bursal infusion decreased perception of pain at resting stage and reduced supplemental analgesic requirement for 2 days postoperatively.

This research analyzed the HRV signals by using wavelet transform to observe the activities of autonomous nervous system in a sleep state. This research also restructured the HRV signals from electrocardiogram and by using coefficient which was obtained through wavelet transform, analyzed the signals by frequency bandwidth. Then compared the analyzed results with existing frequency analyzing method using AR model techniques. The suggested wavelet coefficient from power spectrum component in the study shows a similar tendency with the results from FFT or AR model technique. Therefore, it can be found that power spectrum analyzing method by wavelet coefficient is a useful as a tool for analyzing autonomous nervous system activities using HRV signals. Since the suggested method able to clearly depict the progression of change in time zone, which was once impossible with the existing methods, it is presumed that it will be useful in other physiological signals.

In various sensor network applications, such as climate observation organizations, sensor nodes need to collect information from time to time and pass it on to the recipient of information through multiple bounces. According to field tests, this information corresponds to most of the energy use of the sensor hub. Decreasing the measurement of information transmission in sensor networks becomes an important issue.Compression sensing (CS) can reduce the amount of information delivered to the network and reduce traffic load. However, the total number of classification of information delivered using pure CS is still enormous. The hybrid technique for utilizing CS was proposed to diminish the quantity of transmissions in sensor networks.Further the energy productivity is a test task for the sensor nodes. However, in previous studies, a clustering approach using hybrid CS for a sensor network and an explanatory model was used to investigate the relationship between beam size and number of transmissions of hybrid CS technology. It uses efficient data integration techniques for large networks, but leads to clone attacks or attacks. Here, a new algorithm called SBEA (Snowball Endurance Algorithm) was proposed and tested with a bow. Thus, you can extend the battery life of your WSN by running effective copy detection. Often, multiple nodes, called observers, are selected to verify the reliability of the nodes within the network. Personal data from the source centre (e.g. personality and geographical data) is provided to the observer at the optional witness stage. The trust and reputation system is used to find the reliability of data aggregation across the cluster head and cluster nodes. It is also possible to obtain a mechanism to perform sleep and standby procedures to improve the life of the sensor node. The sniffers have been implemented to monitor the energy of the sensor nodes periodically in the sink. The proposed algorithm SBEA (Snowball Endurance Algorithm) is a combination of ERCD protocol and a combined mobility and routing algorithm that can identify the cluster head and adjacent cluster head nodes.This algorithm is used to yield the network life time and the performance of the sensor nodes can be increased.

Objectives: Nasal continuous positive airway pressure (CPAP) corrected elevated blood pressure (BP) in some studies of obstructive sleep apnea syndrome (OSAS) but not in others. Such inconsistent results in previous studies might be due to differences in factors influencing the effects of CPAP on BP. The factors referred to include BP monitoring techniques, the characteristics of subjects, and method of CPAP application. Therefore, we evaluated the effects of one night CPAP application on BP and heart rate (HR) reactivity using non-invasive beat-to-beat BP measurement in normotensive and hypertensive subjects with OSAS. Methods: Finger arterial BP and oxygen saturation monitoring with nocturnal polysomnography were performed on 10 OSAS patients (mean age $52.2{\pm}12.4\;years$; 9 males, 1 female; respiratory disturbance index (RDI)>5) for one baseline night and another CPAP night. Beat-to-beat measurement of BP and HR was done with finger arterial BP monitor ($Finapres^{(R)}$) and mean arterial oxygen saturation ($SaO_2$) was also measured at 2-second intervals for both nights. We compared the mean values of cardiovascular and respiratory variables between baseline and CPAP nights using Wilcoxon signed ranks test. Delta ($\Delta$) BP, defined as the subtracted value of CPAP night BP from baseline night BP, was correlated with age, body mass index (BMI), baseline night values of BP, BP variability, HR, HR variability, mean $SaO_2$ and respiratory disturbance index (RDI), and CPAP night values of TWT% (total wake time%) and CPAP pressure, using Spearman's correlation. Results: 1) Although increase of mean $SaO_2$ (p<.01) and decrease of RDI (p<.01) were observed on the CPAP night, there were no significant differences in other variables between two nights. 2) However, delta BP tended to increase or decease depending on BP values of the baseline night and age. Delta systolic BP and baseline systolic BP showed a significant positive correlation (p<.01), but delta diastolic BP and baseline diastolic BP did not show a significant correlation except for a positive correlation in wake stage (p<.01). Delta diastolic BP and age showed a significant negative correlation (p<.05) during all stages except for REM stage, but delta systolic BP and age did not. 3) Delta systolic and diastolic BPs did not significantly correlate with other factors, such as BMI, baseline night values of BP variability, HR, HR variability, mean SaO2 and RDI, and CPAP night values of TWT% and CPAP pressure, except for a positive correlation of delta diastolic pressure and TWT% of CPAP night (p<.01). Conclusions: We observed that systolic BP and diastolic BP tended to decrease, increase or remain still in accordance with the systolic BP level of baseline night and aging. We suggest that BP reactivity by CPAP be dealt with as a complex phenomenon rather than a simple undifferentiated BP decrease.

Purpose: The purpose of this study was to investigate the levels of physical symptoms, anxiety, depression, and quality of life (QOL) during chemotherapy for colorectal cancer patients in South Korea and to identify factors influencing their QOL. Methods: Data were collected from 144 colorectal cancer patients receiving chemotherapy during 2012 at one general hospital located in Seoul. Physical symptoms were measured by the M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module, and anxiety and depression were measured by the Hospital Anxiety Depression Scale. QOL was measured by the Functional Assessment of Cancer Therapy-Colorectal. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, $Scheff{\acute{e}}$ post hoc test, Pearson correlation and stepwise multiple regression. Results: Mean age of the participants was 56.6 and most of them were not employed. In terms of cancer stage, 38.2% were in stage 3, followed by stage 4 (34.7%). The most frequent symptom was lack of appetite, followed by sleep disturbance and fatigue. The mean score for anxiety was 5.40 with a prevalence of 23% and that of depression 8.85 with a prevalence of 64.6%. The mean score for quality of life was 81.93 out of 136 and 75.3% of the variance in QOL was explained by depression, symptoms, anxiety, treatment place, and occupational status. Depression was the strongest predictive factor. Conclusion: Oncology professionals need to pay special attention to relieving depression as well as physical symptoms to improve QOL during chemotherapy for colorectal cancer patients.

Objectives: The purpose of this study was to identify the stages of change distributions for nine major health behaviors among poor children in underserved area, and to provide basic information for developing specific objectives and strategies for health education program. Methods: The health behavior data were obtained with a self-administered questionnaire and analysed for 3,081 poor children in 106 local children's centers nationwide. Stages of change classification were based on self-reported responses to five statements. The health behaviors included were balanced diet, safety behavior (helmet and protective device use while riding), regular exercise, smoking, alcohol use, drug use, sleep pattern, weight management and stress management. Results: Poor children were more likely in precontemplation and less frequently in action and maintenance stages for a safety behavior. 33.1% of respondents were precontemplators, 29.9% contemplators, and 6.5% in preparation stage. Only 4.3% and 9.6% were in action and maintenance stages, respectively. Gender differences were apparent. Boys were more likely to be precontemplators for nine health behaviors. Children from the lowest socioeconomic status and disrupted family were more likely to be in precontemplation for weight management and exercise behaviors. Children living with both parents were more likely to be in the action and maintenance stages for nine health behaviors. Stages of change for balanced diet and smoking were significantly related with those for other eight health behaviors. And the stage of exercise adoption was found to be significantly related with those for other seven health behaviors. Conclusion: Safety education must receive high priority in health education program for low income children. Balanced diet smoking cessation and regular exercise could be a possible gateway behavior toward healthier lifestyle practices.

Objectives : We investigated the prevalence and composite score of the neuropsychiatric symptoms in patients with mild cognitive impairment(MCI), and dementia of Alzheimer's type(AD). The aim of this study is to analyze the correlation between the result of Korean Neuropsychiatric Inventory(K-NPI) and cognitive function. Methods : A total of 163 patients diagnosed with MCI or AD was divided into three groups(55 MCI patients, 56 dementia patients with mild stage, and 52 dementia patients with moderate, severe stage). We examined neuro-psychiatric symptoms by K-NPI and compared the prevalence and composite score of each subdomain in K-NPI among three groups. Results : The most common symptoms in the MCI group were depression/dysphoria, sleep/night-time behavior, anxiety, and irritability/lability. In mild AD group, the most frequent disturbance was agitation/aggression, depression/dysphoria, anxiety, apathy/indifference, and sleep/night-time behavior. In moderate to severe AD group, the most frequent disturbance was apathy/indifference, depression/dysphoria, agitation/aggression, and delusion. The frequencies of delusion, hallucination, agitation/aggression, apathy/indifference, aberrant motor behavior, appetite/eating change were statistically significant. The total NPI score showed a negative correlation with MMSE-KC and a positive correlation with GDS. Conclusions : Neuropsychiatric symptoms are common features of MCI and AD. These symptoms observed in MCI are similar to those of mild AD. Psychosis is most common in moderate to severe AD, leading to a faster rate of cognitive decline. Therefore, proper management according to the neuropsychiatric symptoms of MCI and three stages of dementia is needed.

Purpose: The purpose of this study was to examine the effect of a swallowing rehabilitation program for elderly on the stage of dysphagia, nutritional status, and swallowing-quality of life. Methods: The research design was Pretest-Posttest Nonequivalent Groups Design. The subjects of this study consisted of 85 elderly patients hospitalized at geriatric hospitals between August 23rd and October 25th in 2012. Eighty five research subjects were assigned to experimental (42 patients) and control (43 patients) groups. The rehabilitation program was provided to the experimental group 5 days per week for 8 weeks. The effects were evaluated by measurement of Mid-upper Arm Muscle Circumference (MAMC), Total Lymphocyte Counts, albumin, Total Cholesterol, and Swallowing Quality of Life (SWAL-QOL). The collected data were analyzed with x2-test and independent t-test using PASW WIN 18.0. Results: Changes in the stage of dysphagia were not significant (p>.05). In nutrition status, the degree of MAMC points in the experimental group was significantly increased compared with that in the control group (t=2.36, p=.021). In swallowing quality of life, the score of SWAL-QOL in the experimental group was significantly increased, particularly burden (t=3.34, p=.002), frequency (t=2.68, p=.011), fear (t=2.44, p=.019), mental health (t=2.47, p=.018), and sleep (t=2.08, p=.044). Conclusion: Based on the results, this swallowing rehabilitation program for elderly would be helpful in promoting their nutritional status and swallowing-QOL in geriatric hospitals.
