Background: Resting-state functional connectivity (rs-FC) may aid in understanding the link between painmodulating brain regions and the descending pain modulatory system (DPMS) in fibromyalgia (FM). This study investigated whether the differences in rs-FC of the primary somatosensory cortex in responders and non-responders to the conditioned pain modulation test (CPM-test) are related to pain, sleep quality, central sensitization, and the impact of FM on quality of life. Methods: This cross-sectional study included 33 females with FM. rs-FC was assessed by functional magnetic resonance imaging. Change in the numerical pain scale during the CPM-test assessed the DPMS function. Subjects were classified either as non-responders (i.e., DPMS dysfunction, n = 13) or responders (n = 20) to CPM-test. A generalized linear model (GLM) and a receiver operating characteristic (ROC) curve analysis were performed to check the accuracy of the rs-FC to differentiate each group. Results: Non-responders showed a decreased rs-FC between the left somatosensory cortex (S1) and the periaqueductal gray (PAG) (P < 0.001). The GLM analysis revealed that the S1-PAG rs-FC in the left-brain hemisphere was positively correlated with a central sensitization symptom and negatively correlated with sleep quality and pain scores. ROC curve analysis showed that left S1-PAG rs-FC offers a sensitivity and specificity of 85% or higher (area under the curve, 0.78, 95% confidence interval, 0.63-0.94) to discriminate who does/does not respond to the CPM-test. Conclusions: These results support using the rs-FC patterns in the left S1-PAG as a marker for predicting CPM-test response, which may aid in treatment individualization in FM patients.

The purpose of this study was to develop a new nursing unit which can meet changing health care needs, enhance patients' satisfaction and nurses' job satisfaction, and finally guarantee quality nursing care with present manpower. For this, one medical unit was selected as a unit for quality care. And one medical unit which is similar in staffing and patients' characteristics was selected as a control unit. To assess present problems and identify the remedies to the problems a hospital-wide survey and a workshop were performed. According to the survey results, educational programs and improvement of the facilities and equipment supply system, managereal support for interdepartmental cooperation and intensification of bed-side nursing care were adopted as main principles for operating model unit, This model unit was operated for 3 months from Sep. 1, 1992 to Nov. 30, 1992. To evaluate the effectiveness of the model unit, derect/indirect nursing care hours, patients' satisfaction to nursing care, nurses' job satisfaction, and quality care index were measured. Direct/indirect nursing care hours were compared with that of the control unit, and patients' and nurses' satisfaction and quality care index were measured before and after operating model unit and compared with each other. The results of the study were as follows; 1. In the model unit mean direct nursing care hours per cach shift was 146.88 minutes and indirect nursing care hours was 354.72 minutes. The ratio of the direct nursing care hour to indirect nursing hour was 29.6 ; 70.4 and that of the control unit was 26.9 : 73.1. Direct nursing care hour in model unit was longer than that of the control unit. But, the difference was not significant. In subcategories of direct nursing care, the time spent in mobility and exercise, conservation of body temperature, hygiene, and communication and health education were longer than that of the con" trol unit. 2. Indirect nursing care hour in model unit was shorter than that of the control unit. But, the difference was not significant. In subcategories of indirect nursing care, the time spent in drug management and ward arrangement was shorter than that of the control unit. 3. Patients' satisfaction to nursing care was increased significantly after operating the model unit (T=-3.48, P=-0.002) and satisfaction to subcategories of physical comfort measure, psychological cate, and unit management components were significantly higher than before. 4. In the model unit, nurses' total job satisfaction was increased significantly after operating the model unit(Z=2.1004, P=.0357) and satisfaction to subcategory of satisfaction to administration was significantly higher than before (Z=-2.0732, P=.0382). 5. After operating the model unit, quality care index was increased from 89 to 93. With this results, it can be summarized that all the measures tried for quality care, such as educational programs, managereal support for interdepartmental cooperation, and improvement of the equipment and facility provision resulted in partial increase in direct nursing care hours, nurses satisfaction to their job and patients' satisfaction to nursing care. In can be postulated that managereal support and motivation without proper staff supplementation is not enough for increasing direct nursing care hours. And for the enhancement of the level in clinical nursing, and staff supplement must be considered sincerely and the measures for reducing indirect nursing care hours, such as computerization of nursing care activities, improvement of facilities and equipment and facilities supply system, must be instituted in addition.

There has recently been a trend that IT industry is united with traditional industries such as military, aviation, automobile, and medical industry. Therefore, embedded software which controls hardware of the system should guarantee the high reliability, availability, and maintainability. To guarantee these properties, there are many attempts to develop the embedded software based on COTS (Commercial Off The Shelf) hardware components. However, it can cause additional faults due to software/hardware interactions beside general software faults in this methodology. We called the faults, Linkage Fault. These faults have high severity that makes overall system shutdown although their occurrence frequency is extremely low. In this paper, we propose a new software reliability model which considers those linkage faults in embedded software development with COTS hardware components. We use the Bayesian Analysis and Markov Chain Monte-Cairo method to validate the model. In addition, we analyze real linkage fault data to support the results of the theoretical model.

This paper convergent examined caregiver burden, depressive symptoms and health related quality of life of 226 caregivers of stroke patients, who had been hospitalized in 7 general hospitals located in Cheongju and Daejeon Metropolitan city. The quality of life was measured using SF-8, which is a short version of HRQoL. According to Multiple regression Analysis, dependence of a patient were important factors in the physical related quality of life. These results suggest that in order to improve the quality of life related to the physical health of the stroke patient's caregiver, the elderly long-term care insurance system and the caregiver system and the ward of the Ministry of Health and Welfare are expanded ward without a caregiver. There is a need to raise expectations for recovery through education and family support groups.

This study was designed to investigate differences in some aspects of value conceptions in fundamentals of nursing functions between nursing service personnel and nurse-educators. The purpose of the study was to identify the difference of value conceptions between the hospital nurses and school instructors, to contribute as a reference in strengthening the educational program in establishing nay hinder professional growth. The questionaries of this study were focused in the following aspects: 1) establishment of nursing service management system, 2) strengthening of the professionalization of nursing service, 3) hindrance in accomplishment of independent nursing functions, 4) communication skills in nurse-patient relationship, 5) activities directly related to nursing care planning, 6) communication skills in nurse-doctor relationship, 7) attitude towards taking responsibilities for patient- centered nursing approach, and 8) nursing educational approach towards preparation of professional competence in practicing independent nursing functions. 265 graduate nurses from 14 general hospitals and 88 nursing instructors from 18 schools, collegiate and diploma, were sampled. The main findings of the study were as follows; 1. Both groups responded highly in the lack of public recognition of nursing profession and hospital administrators support in establishment of nursing service management system. Further investigation is needed to define some relationship between the intrinsic and extrinsic factors which might give influence to the professional development. 2. while hospital nursing personnel responded on environmental pressure such as a heavy nursing load as the factor giving hindrance to independent nursing functions, the nurse educators responded highly on lack of nursing competence of individual nurses. An emphasis should be placed on the development of nursing interaction through professional education. If the professional model is not well established, nursing function will be limited to medical assistance. 3. 3. The patient-centered approach for nurse-patient communication had given positive respond for both group, tut lacks in team concept in problem solving process. There exist a social distance between nurses and other professional co-workers in the hospital hierarchy. 4. It was indicated that, as an intrinsic factor in the development of nursing service and nursing education, building up a philosophical basis is an utmost importance. This question is opened for further and extensive study to clarify whether existence of philosophical absence or philosophical stasis in nursing profession hinders the development.

As the elderly population increases, real-time personal health monitoring is gaining new ground with advances in wireless communications. Such an approach is particularly beneficial to elderly and physically challenged people, as well as those who live alone and are not be able to seek help in case of medical emergencies. The aim of this study is to implement a wearable band which monitors personal vital signs, such as the body temperature and heart rate, and assists with healthcare decisions using a fuzzy logic based decision support system. Since the vital sign data measured from sensors are imprecise and their normal variation with age is nonlinear and not crisp, a fuzzy system is employed to deal with this imprecise or uncertain information. The proposed wearable band is designed to continuously capture and transmit vital signs and healthcare decisions to suitable apps developed for smartphones. In this way, health alerts can be sent to the guardian or caregiver who is registered in the apps.

With high interest in the patient satisfaction of emergency medical services, there is a lot of effort into improving the process of Emergency Department(ED) utilizing the technology of Internet of Things(IoT). In this study, the core technologies of smart ED are examined and a decision support algorithm for medicine tasks is proposed. The proposed algorithm minimizes the decision risks such as task selection accountability, patient complaints, care delays and longer stay time. It can reduce the nurses burnout and improve the patient care with kindness and consideration. Ultimately, patient satisfaction, job satisfaction and professional identity of nurses can be increased. The comparative study was carried out by simulation in terms of the average length of patient stay in a simplified hypothetical ED system. In all the cases, the proposed algorithm was shown to perform substantially better than the other rule.
