This is to improve the complicate process of the existing CD copy flow in Department of Radiology. It is also to improve the medical service of the hospital to secure private information of patients. Survey: The patients who ask for CD copies in the Department of Radiology of this hospital(for 6 months in 2010). Time: Comparing the total amount of time of the previous and the modified CD copy flow. Using the SPSS 12.0 program for testing significance of independent two-samples t-test. Private information: Introducing the identification-system based on the medical law to supplement the security of personal information of patients. There was manifold complaints due to receipt and issuing the prescription in Admission and Discharging office and outpatient department. The time has been approximately 50% reduced from 70 mistunes to 32 mistunes due to simplifying the routes. The security of the personal information has been supplemented by let patients submit documentary evidence based on the medical law. The service in the hospital has been improved as a result of simplifying the whole process of the routes and receipt process. Therefore, the each stage of waiting time has been decreased. In addition, the personal information of the patients has been more secured.

Objective : This study examines whether functional motion is present at one or more years after Bioflex System placement. BioFlex System is a flexible rod system which has been used to preserve motion at the area of implantation. There has not been a scientific study showing how much motion is preserved after implantation. Methods : A total of 12 consecutive patients underwent posterior dynamic stabilization using the BioFlex System. Six patients were treated using a L3-4-5 construct and other six patients using a L4-5-S1 construct. Follow-up ranged from 12 to 33 months and standing neutral lateral, extension, flexion and posteroanterior (PA) radiographs were obtained at 3, 6, 9, and 12 months and at more than 12 months postoperatively. Range of motion (ROM), whole lumbar lordosis, and ROMs of motion segments from L2 to S1 were determined. Results : Patients with a L3-4-5 construct demonstrated a decrease in mean ROM for whole lumbar decreased from 40.08 to 30.77. Mean ROM for L3-4 (6.12 to 2.20) and L4-5 (6.55 to 1.67) also decreased after one year. Patients with a L4-5-S1 construct demonstrated L4-5 (8.75 to 2.70) and L5-S1 (9.97 to 3.25) decrease of mean ROM at one year postoperatively. Lumbar lordosis was preservep at both L3-4-5 and L4-5-S1 constructs. Clinical results showed significant improvements in both study groups. Conclusion : The present study provides preliminary information regarding the BioFlex motion preservation system. We conclude that the BioFlex System preserves functional motion to some degree at instrumented levels. However, although total lumbar lordosis was preserved, ROMs at implantation segments were lower than preoperative values.

In the development of the totally implantable artificial heart (TAH), the information of the preload condition is important to ind appropriate condition or the automatic control of the heart. Our TAH configuration consists of two artificial ventricles, and brushless DC motor within actuator. The pressure between ventricles could indicate the preload condition during the TAH operation. If we can measure accurately inspite of the noise induced from TAH and environmental condition. We suggested integrating a feedback loop to remove an unexpected DC drift. NPI 19-series Nova sensor was used which could measure pressure in gas and liquid. This method and sensor enabled us to develop the pressure transducer compact so (that) the systems can be implanted with TAH into patient. This system has been verified in vitro and in vivo test. This results showed that the output waveform of this system was stable irrespective of animal condition.

Background: Presently, a multidisciplinary team of doctors, pharmacists, nurses, and dietitians provides patient education to impart information on chemotherapy. However, studies on multidisciplinary education satisfaction are inadequate. In this study, we aimed to contribute to the improvement of quality of multidisciplinary education counseling for patients with cancer by developing a satisfaction questionnaire and analyzing the satisfaction survey. Methods: A questionnaire was developed by an expert group, and the responses were recorded using the 5-point Likert scale. After conducting a pre-test, factor analysis was performed to evaluate validity. The reliability of the questionnaire was measured by Cronbach's alpha coefficient. A satisfaction survey was conducted by self-administration method. Results: Based on the results of factor analysis, factors can be divided into two parts: "overall education" and "each team member's education" (total 14 questions). The construct validity and reliability of the questionnaire are sufficiently high. Fifty-one patients took the survey between January 2, 2018 and January 20, 2018. Twenty-six (51%) patients responded that they were "very satisfied" and 22 (43.1%) patients responded that they were "satisfied". Conclusion: By developing a questionnaire on multidisciplinary education counseling for patients with cancer, it is possible to perform evaluation and research of cancer patient education. This study will contribute to the management and improvement of quality of multidisciplinary education.

This study is to investigate the effects of manual lymphatic drainage of stressed hospital office employees on the autonomic nervous. A total of 30 stressed hospital office women voluntarily participated in the study. The participants were randomized to the manual lymphatic drainage groups and rest groups. The intervention was conducted for 20 minutes in each group. There were significant differences in sympathetic nerve, parasympathetic nerve, and pain within manual lymphatic drainage groups(p<.05). There were significant differences between groups for the sympathetic nerve, parasympathetic nerve, and pain(p<.05). Therefore, manual lymphatic drainage is an effective intervention for reducing the stress and pain of stressed hospital office employees.

Osteonecrosis of the femoral head (ONFH), a condition characterized by the presence of a necrotic bone lesion in the femoral head, is caused by a disruption in the blood supply. Its occurrence is more common in young and middle-aged adults and it is the main reason for performance of total hip arthroplasty in this age group. Its incidence is increasing along with increased use of glucocorticoids for management of adjuvant therapy for treatment of leukemia as well as organ transplantation and other myelogenous diseases. Current information on etiology and pathogenesis, as well as natural history, stage system, and treatments is provided in this review. A description of the Association Research Circulation Osseous (ARCO) criteria for classification of glucocorticoids-and alcohol-associated ONFH, 2019 ARCO staging system, and 2021 ARCO classification using computed tomography for the early stages of ONFH is also provided.

Purpose: To analyze trends related to demography and EMS and to provide supporting data for the appropriate deployment of EMS providers. Methods: In this cross-sectional study, data on patients transported by 119 EMS, demographics, and EMS factors were collected using the Korean Statistical Information Service (KOSIS) and the National Fire Agency annual report from 2017 to 2021. Results: During the study period, the total number of patients and those with severe disorders transported via 119 EMS showed an increasing trend. The total fertility rate and population during the same period tended to decrease, and the population density and number of households increased; however, there was a disparity between regions. The main demographic factors affecting the number of patients transported were population density and total fertility rate, while the main EMS factors were the number of ambulances and provision of emergency medical information services(hospital guidance, pharmacy information, and first aid guidance). Conclusion: From the perspective of EMS providers' force deployment, it is necessary to consider population density, population, number of households, total fertility rate, and number of emergency medical institutions and to strengthen the role of diverting the use of 119 EMS by minor patients by providing emergency medical information.

Objectives This study aimed to examine the efficacy of Korean traditional medicine treatments for recurrent lumbar disc herniation by analyzing randomized controlled trials (RCTs). Methods The following 6 databases were used Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, Research Information Sharing Service, ScienceON, PubMed, and China National Knowledge Infrastructure. Only RCTs were selected. The risk of bias was assessed by Cochrane's risk of bias tool. Results A total of 10 RCTs were analyzed, which utilized 8 types of interventions, including acupuncture, moxibustion, warm needling, electroacupuncture, herbal medicine, cupping, and chuna manual therapy. Acupuncture and moxibustion were the most frequently used treatments. There were 7 outcome measures, including the effective rate, visual analog scale, Japanese Orthopedic Association. The effective rate was assessed in all studies. Meta-analysis results indicated that warm needling therapy and traditional Chinese medicine interventions were more effective compared with the control. Conclusions In this study, warm needling therapy and herbal medicine interventions demonstrated beneficial effects. As the meta-analysis was conducted with only a subset of RCT studies, further large-scale, systematic RCT studies are needed.

Background: We analyzed changes in the doses, structure volumes, and dose-volume histograms (DVHs) when data were transferred from one commercial treatment planning system (TPS) to another commercial TPS. Materials and Methods: A total of 22 volumetric modulated arc therapy (VMAT) plans for nasopharyngeal cancer were generated with the Eclipse system using 6-MV photon beams. The computed tomography (CT) images, dose distributions, and structure information, including the planning target volume (PTV) and organs at risk (OARs), were transferred from the Eclipse to the MRIdian system in digital imaging and communications in medicine (DICOM) format. Thereafter, DVHs of the OARs and PTVs were generated in the MRIdian system. The structure volumes, dose distributions, and DVHs were compared between the MRIdian and Eclipse systems. Results and Discussion: The dose differences between the two systems were negligible (average matching ratio for every voxel with a 0.1% dose difference criterion = $100.0{\pm}0.0%$). However, the structure volumes significantly differed between the MRIdian and Eclipse systems (volume differences of $743.21{\pm}461.91%$ for the optic chiasm and $8.98{\pm}1.98%$ for the PTV). Compared to the Eclipse system, the MRIdian system generally overestimated the structure volumes (all, p < 0.001). The DVHs that were plotted using the relative structure volumes exhibited small differences between the MRIdian and Eclipse systems. In contrast, the DVHs that were plotted using the absolute structure volumes showed large differences between the two TPSs. Conclusion: DVH interpretation between two TPSs should be performed using DVHs plotted with the absolute dose and absolute volume, rather than the relative values.
