This paper describes a design of a Wavelet Adaptive Filter(WAF) for the removal of the baseline wandering and the minimization of the signal distortion using by wavelet transform and adaptive filter in the ECG signal. WAF consists of two parts. The first part is wavelet transform that decomposes the ECG signal into seven frequency bands using Vaidyanathan and Hoang wavelet. The second part is adaptive filter that uses the signal of seventh low frequency band among the wavelet transformed signals as primary input and a unit impulse sequence as reference input. For the evaluation of the performance of WAF, we used several baseline wandering elimination filters such as commerical standard filter with cutoff frequency of 0.5Hz and general adaptive filter. We made use of MIT/BIH database and real patient data for the evaluation. In conclusion, WAF showed a lower ST segement distortion than standard filter and adaptive filter and has a higher eliminated noise power than standard filter and adaptive filter.

This paper proposes a new method for planning randomized clinical trials. This method is especially suited to comparison of a best standard or control treatment with an experimental treatment. Patients are allocated into two groups by a random or chance mechanism. Patients In the first group receive standard treatment; those in the second group are asked if they will accept the experimental therapy; if they decline. they receive the best standard treatment. In the analyses of results. all those in the second group. regardless of treatment. are compared with those in the first group. Any loss of statistical efficiency can be overcome by Increased numbers. This experimental plan is indeed a randomized clinical trial and has the advantage' that, before providing consent, a patient will know whether an experimental treatment is to be used.

The TMO may contain two types of methods, time-triggered methods(also called the spontaneous methods of SpMs) which are clearly separated from the conventional service methods (SvMs). The SpM executions are triggered upon design time whereas the SvM executions are triggered by service request message from clients. In this paper, we describes the application environment as the patient monitor telemedicine system with TMO structure. Vital sign information web viewer systems is also the standard protocol for medical image and transfer. In order to embrace new technologies as telemedicine service, it is important to develope the standard protocol between different systems in the hospital, as well as the communication with external hospital systems.

The cerebrospinal fluid tap test (CSFTT) is recommended as a key step in the diagnosis of idiopathic normal pressure hydrocephalus (iNPH). While there is no generally accepted evaluation period for ascertaining a CSFTT responder, a substantial number of patients are evaluated only once within 24 hours of the test for improvement in gait. We report an iNPH patient with a favorable response to shunt surgery, who was first judged a non-responder by this standard, though subsequently was judged a responder in virtue of repetitively testing gait over 7 days. A 68-year-old man presented with progressive impairment of gait, balance, and memory. He was diagnosed as iNPH with an Evans' ratio of 0.35. At first hospitalization, change in gait was evaluated 24 hours after the CSFTT. He didn't show any significant improvement and was judged as a non-responder. However, at the second CSFTT, we repetitively tested his change in gait over seven days. Forty-eight hours after the tap, he showed significant improvement in his gait. He was then confirmed as a responder. After the operation, the gait difficulties were almost fully resolved. Further studies developing the standard procedure of the CSFTT should be considered.

1. Objectives The objective of this paper is to understand on treatment of in critical state patients based on the text book of Sasang Constitutional Medicine. We expect this study can be helpful in treating the critical state patients. 2. Methods The study is mainly based on the bibliographical research on the "Dongyisoosebowon" and on the "Principle of dosing for patient in critical state". 3. Results and conclusions Lee je-ma suggested a health scale which people can measure his health grade from a standard healthy state to severe diseases. We investigated the treatment of 'critical state' patients according to his scale. Lee je-ma also confirmed the standard dose of herbs and how to take herbs in compliance with the state which each patient in. We tried to find a rules of treating the critical state patients based on the text "Dongyisoosebowon" and we suggested brief principles in treating patients.

Purpose: Addressing current status of nursing handoff provides information as to where to change practice for improvement in patient care. The aim of this study was to develop nursing a handoff practice guideline and standardsfor Korean hospitals. Methods: A questionnaire was used to collect data in a cross-sectional survey with 207 head nurses and 697 nurses working in general hospitals. Results: The practice guideline consisted of 2 items on purpose of handoff, 5 items on policy, 3 on environment, 5 on process, 7 on content, 3 on evaluation, and 1 on the function of education, for a total 26 of items. Standard instruction was developed related to Patients, Assessment, Situation, Safety concerns, Background, Actions, and Recommendations. Conclusion: The findings of this study indicate that the guideline can be applied in real nursing practice to improve the effectiveness of handoff procedures. It can be used to guide nurses to follow the standardized content, which presents patient details clearly. The guideline provides consistency and structure for the information that is handed over.

Mobile Health (M-Health) system is a recent term for medical and public health practice supported by mobile devices, such as mobile phones, PDAs, and other wireless devices. Mobile Health system has been successfully establishing at few general hospital in Korea. However, to use diverse devices manufactured by various company cause inoperability, and lack of security disappoints customers often. Although the outstanding health environment, most of hospitals are unavailable to share electronic patient records due to lack of standard protocol to handle the interoperability each other. Health Level 7 (HL7) is the best solution for the problem. In this paper, we will analyse a current M-Health service in terms of security and mobile device, and suggest iPhone for the best device against hospital environment. Also, for keep confidentiality of health information and patient privacy, enhanced security mechanism is introduced. As a consequence, interoperable standard, and most appropriate device for supporting staffs and M-Health performance, and enhanced securirty mechanism will be integrated in order to propose improved M-health model.

Background: Small cell lung cancer (SCLC) tends to grow more rapidly and spread much faster than non-small cell lung cancer (NSCLC). A concurrent combination of chemotherapy and thoracic radiotherapy is suggested as the standard conventional treatment, but it is more challenging for elderly patients having pulmonary and cardiovascular comorbidities. Case presentation: Here we present a case of an 80-year-old male, current smoker diagnosed with SCLC in limited stage T3N0M0 (36mm right upper lobe, satellite nodule) in Dec, 2015. The standard concurrent chemoradiotherapy was not available for his comorbidities, which included chronic obstructive pulmonary disease (COPD) and angina pectoris. Furthermore, he and his family refused the recommended chemotherapy or radiotherapy exclusively. Alternatively, he received various non-conventional treatments including local radiofrequency hyperthermia, mistletoe, and Traditional Korean medicine including acupuncture, moxibustion and herbs since Jan. 2016. Despite the progression in primary tumor size, there have been no other distant relapse so far, and the patient has been in stable condition ever since. Conclusion: We suggest that a combination of various alternative treatments could be a candidate for elderly patients intolerable to conventional cytotoxic treatments.

Stereotactic radiosurgery is one of the most sophisticated forms of modern advanced radiation therapy. Unlike conventional fractionated radiotherapy, stereotactic radiosurgery uses a high dose of radiation with steep gradient precisely delivered to target lesions. Lars Leksell presented the principle of radiosurgery in 1951. Gamma Knife^® (GK) is the first radiosurgery device used in clinics, and the first patient was treated in the winter of 1967. The first GK unit had 179 cobalt 60 sources distributed on a hemispherical surface. A patient could move only in a single direction. Treatment planning was performed manually and took more than a day. The latest model, Gamma Knife^® Icon^TM, shares the same principle but has many new dazzling characteristics. In this article, first, a brief history of radiosurgery was described. Then, the physical properties of modern radiosurgery machines and physicists' endeavors to assure the quality of radiosurgery were described. Intrinsic characteristics of modern radiosurgery devices such as small fields, steep dose distribution producing sharp penumbra, and multi-directionality of the beam were reviewed together with the techniques to assess the accuracy of these devices. The reference conditions and principles of GK dosimetry given in the most recent international standard protocol, International Atomic Energy Agency TRS 483, were shortly reviewed, and several points needing careful revisions were highlighted. Understanding the principles and physics of radiosurgery will be helpful for modern medical physicists.
