Purpose The purpose of this study was to examine the relationship between physical activities, sleep disturbance, and health related quality of life (HRQOL) in patients with chronic obstructive pulmonary disease (COPD). Methods A descriptive survey design used pretest dataset of COPD symptom management intervention study (N=245). Measures included the international physical activity questionnaire, the COPD and asthma sleep impact scale, and the St. George's respiratory questionnaire of HRQOL. The data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficients, and simultaneous multiple regression by the SPSS WIN 18.0 program. Results The mean scores (SD) of HRQOL and sleep disturbance were 36.04 (19.43) and 14.33 (6.20), respectively. About 32% of participants were physically inactive. The multivariate approach showed the patients who have more sleep disturbance (β=.27), lower levels of FEV1 % predicted (β=-.23), lower physical activities (β=-.19), lower household income (β=-.16), and diagnosed longer than 5 years (β=.14) reported lower HRQOL (R²=.34). Conclusion The findings of this study suggest that improving the quality of sleep and physical activities can be efficient strategies for HRQOL in patients with COPD. Future research in enhancing HRQOL through improving sleep quality and physical activities is needed.

Recently, A utilization request of the U-Healthcare services are increasing rapidly. This is because the increase in smartphone users and ubiquitous computing technology was developed. Furthermore, the demand for access to and use of medical information systems is growing rapidly with a smartphone. This system have the advantage such as they can access from anywhere and anytime in the healthcare information system using their smartphone quickly and easily. But this system have various problems that are a privacy issue, the location disclosure issue, and the potential infringement of personal information. this problems are arise very explosive. Therefore, we propose a secure information security system that can solve the security problems in healthcare information systems for healthcare workers using smartphone. Our proposed system, doctors record, store, modify and manage patient medical information and this system would be safer than the existing healthcare information systems. The proposed system allows the doctor to perform further authentication by transmitting using SMS to GOTP message when they accessing medical information systems. So our proposed system can support to more secure system that can protect user individual information stealing and modify attack by two-factor authentication scheme. And this system can support confidentiality, integrity, location information blocking, personal information steal prevent using cryptography algorithm that is easy and fast.

Background: The left main coronary artery surgical angioplasty has become the choice of surgical procedure in isolated LM disease. We have performed 22 cases of LMCA surgical angioplasy since 1996. We report the immediate and long term result of the surgical angioplasty with their postoperative angiography. Material and Method: Between July 1994 and October 2000, 22 patients(11 men and 11 women) were subjected to surgical patch angioplasty of the LMCA, 1 patient had an additional angioplasty performed on the proximal right coronary artery. The LMCA was approached anteriorly with or without transection of the main pulmonary artery(21 cases), and in a patient who had undergone an aortic valve replacement, LMCA was approached superiorly with transection of the ascending aorta. Additional grafting was required in 5 cases. The on-lay patch was used with autologous pericardium in 6 cases and bovine pericardium in 16 cases. Result: There was no operative mortality. There was 30~50% stenosis of the anastomosis site in 3 cases at the postop. coronary angiography. Coronary angiography was reperformed in 5 cases between 5th months and 15th months postoperatively. There was 40~60% stenosis of the anastomosis site in 2 cases. There was one death at 42nd months postoperatively but the cause was unknown. No patient complained of angina with a mean follow up of 48.$\pm$22.5 months. Conclusion: There were only several coronary angiographic results in long term follow-up but we had relatively good clinical results for LMCA surgical angioplasty in the immediate and long term. The excellence of LMCA surgical angioplasty needs the result of the long term follow-up.

Purpose: In this report we are going to discuss about the functional evaluation and the outcome of treatment of metastatic tumor in the lower extremities treated with tumor prosthetic arthroplasty. Materials and Methods: This report is based on nine patients diagnosed as a metastatic tumor and treated by tumor prosthetic arthroplasty, from June 1998 to December 2001. Age of the patients ranged from 49 to 63 with the average of 56.3. The average follow up period was 23.4 months. Two patients had lung cancer, three had breast cancer, two had renal cancer, one colon cancer, and one had multiple myeloma. All these were primary cancers. The site of metastasis were six in proximal femur, two in distal femur, and one in proximal tibia. Tumor excision was performed after biopsy in following the principle of primary tumor management. Excision with wide surgical margin was tried as possible could. Six cases were treated with tumor prosthesis, and the other three cases were reconstructed with bone cement and arthroplasty. Results: The functional evaluation in the extremities at the last follow up was performed on Enneking evaluation score with 6 categories. The highest scored 26, and the lowest scored 10, with an average of 19.5. A case in which the patient died 15 days after the operation was excluded from the evaluation. Among the categories, emotional acceptance to postoperative function and pain relief were highly scored. At the final follow up, seven patients survived, and one colon cancer patient died 68 days after operation. Conclusion: Metastatic tumor occurring in joints of lower extremities could be treated in accordance to the treatment principle of primary tumor. By insertion of tumor prosthesis, we can get satisfactory results of function in the lower extremity and pain relief especially. So, this aspect of medical favor must be considered in treating patients.

Background : The prone position is often used for operations involving the spine and provides excellent surgical access. The complications associated with the prone position include ocular and auricular injuries, and musculoskeletal injuries. In particular, the prone position during general anesthesia causes hemodynamic changes. To evaluate the cardiovascular effects of the prone position in surgical patients during general anesthesia, we investigated the effects on hemodynamic change of the prone position with the Jackson spinal surgery table. Materials and Methods : Thirty patients undergoing spine surgery in the prone position were randomly selected. After induction of general anesthesia, intra-arterial and central venous pressures (CVP) were monitored and cardiac output was measured by $NICO^{(R)}$. We measured stroke volume, cardiac index, cardiac output, mean arterial pressure, heart rate, CVP and systemic vascular resistance (SVR) before changing the position. The same measurements were performed after changing to the prone position with the patient on the Jackson spinal surgery table. Results : In the prone position, there was a significant reduction in stroke volume, cardiac index and cardiac output. The heart rate, mean arterial pressure and CVP were also decreased in the prone position but not significantly. However, the SVR was increased significantly. Conclusion : The degree of a reduced cardiac index was less on the Jackson spinal surgery table than other conditions of the prone position. The reduced epidural pressure caused by free abdominal movement may decrease intraoperative blood loss. Therefore, the Jackson spinal surgery table provides a convenient and stable method for maintaining patients in the prone position during spinal surgery.

This paper proposes that people with disability can be successfully supported by smart homes only when their needs of the technological interventions are understood and integrated in traditional universal design. Understanding the patient's home environment is an integral part of treatment and discharge planning. This paper suggests on architectural barriers commonly found in the home, ways to eliminate them and a general overview of methods for assessment and intervention. It is expected that the electronics, information and communication technology can be an alternative of traditional universal designs for motor dysfucntion, sensory dysfunction and cognitive dysfunction.

Purpose: The purpose of this study was to explore adult diabetics' eating styles and factors which influence them. Method: The study adopted an ethnographic method based on a perspective which views the eating style as a cultural phenomenon. Data was collected through a personal interview, participant observation, and documented materials from Oct.2001 to Sept. 2002. In this study, fifteen adult diabetics, with an average age of 57, participated. Data analysis was done by the Spradley's taxonomic analysis technique. Result: The patients' eating styles were rooted in their viewpoint on illness as well as the meaning of food. Eating styles were classified into 4 types: Pathology-centered, symptom-centered, need-centered, and role-centered. Conclusion: A conventional approach to the treatment and management of diabetes did not consider the patient's inner world which may play an important role in the successful management of the disease. We found that it was critical for health care personnel to understand patients' values, beliefs and their way of life in order to facilitate the most successful self-care diet.

Successful root canal treatment can be obtained by the removal of microorganisms from the pulpal space of the root canal system through biomechanical technique with instruments and irrigation. Due to the difference in the dimension of the pulpal structure such as thin wall of the root, large portion of chamber, the primary teeth should be considered in a different way of approach. Traditionally, fluids have been dispensed passively into the root canals for improve the cleansing. The use of sodium hypochlorite as an irrigant in root canal treatment is widespread and common, because it meets requirements for the ideal irrigants.
