Background: Parkinson's disease (PD) is a neurodegenerative disorder that is the second most common disorder after Alzheimer's disease. PD includes both "motor" and "non-motor" symptoms, one of which is pain. The aim of this study was to investigate the clinical characteristics of pain in patients with PD. Methods: This cross-sectional study included 250 patients diagnosed with PD, 70% of which had mild to moderate PD (stages 2/3 of Hoehn and Yahr scale). The average age was 67.4 years, and the average duration since PD diagnosis was 7.1 years. Relevant data collected from PD patients were obtained from their personal medical history. Results: The prevalence of pain was found to be high (82%), with most patients (79.2%) relating their pain to PD. Disease duration was correlated with the frequency of intense pain (R: 0.393; P < 0.05). PD pain is most frequently perceived as an electrical current (64%), and two pain varieties were most prevalent (2.60 ± 0.63). Our findings confirm links between pain, its evolution over time, its multi-modal character, the wide variety of symptoms of PD, and the female sex. Conclusions: Our results demonstrated that the pain felt by PD patients is mainly felt as an electrical current, which contrasts with other studies where the pain is described as burning and itching. Our classification is innovative because it is based on anatomy, whereas those of other authors were based on syndromes.

기존의 CPM 관리방식은 정해진 시간과 비용 내에서 프로젝트를 완료하기 위한 목적으로 건설분야에 활용되어 공기지연이 발생하지 않도록 관리하는데 초점을 두고 있으나, 조기 완공을 유도하지는 못하여 왔다. 기존의 CPM 공정계획의 경우에 학생증후군(Student Syndrome)과 파킨슨법칙(Parkinson's Law)이 작용할 경우 조기 완공의 효과를 얻기는 어렵다. 본 연구는 건설 프로젝트의 공기 산정에 제약이론(Theory of Constraints)을 적용하였으며, 이는 공정계획에서의 새로운 관리기법을 개발하는데 사용되어온 Critical Chain을 일컫는다. 이러한 Critical Chain의 개념은 기존 공정계획 방법에서의 문제점을 해결하기 위하여 이용되었다 본 논문에서는 기존 공정계획 방법의 문제점을 해결하기 위하여 Critical Chain의 개념을 적용하여 확률적인 공기산정과 공정버퍼(buffer)를 이용한 공정계획 합리화 방안을 제시하였다.

The aim of this study is to confirm clinical usefulness of magnetocardiogram (MCG) by analyzing MCG data of health subjects and patients with Wolff-Parkinson-White (WPW) syndrome and dilated cardiomyopathy (DCM). Measurement of MCG signals was done with a home-made 40-channel SQUID system. MCG signals of 30 healthy subjects were measured as the reference of MCG signals. Among the DCM patients, 7 patients showed abnormal the direction of T wave vector. For a WPW syndrome patient, we measured the MCG signals before and after the surgery. and compared the difference. From the measured magnetic field distribution, current vector map was obtained to show the myocardium current activity. By comparing the MCG signals and current maps, we showed the differences in the analysis results between the healthy subjects and patients with heart diseases.

목적 : 좌각차단이나 우심실조율박동과 같은 부정맥을 가진 환자들에서 심근관류는 의미있게 변화한다는 것이 알려져 있다. 비정상적인 심근관류는 심실조기흥분에 의해서도 야기될 수 있다고 알려져 있지만, 그 위치 범위 강도와 부전도로와의 관계는 아직 정립되어 있지 않았다. 이에 WPW 증후군 환자에서 부전도로의 위치와 SPECT상에서 관류양상의 관계에 대해 알아보고자 하였다. 대상 및 방법 : WPW 증후군 환자 11명에 대해 Adenosine 99m-Tc MIBI 또는 Tl-201 심근관류 SPECT를 시행하였다, 관류결손은 Fitzpatrick's algorithm을 기초로 한 심전도 또는 전기생리학적검사 및 전극도자 절제술을 이용한 부전도로의 위치와 비교하였다. 결과: 11명의 환자들의 평균 나이는 $39.9{\pm}8.6$세 였고, 비특이적인 흉통을 호소하거나, 증상이 없었다. 11명 모두 관삳동맥의 위험도에 관한 계산도표를 이용하여 관상동맥질환의 확률을 예측했으나 0.1 이하로 위험도가 낮았고 이중 4명은 관상동맥조영술을 시행한 결과 3명은 정상이었고 1명은 관동맥 협착 (50%) 부위의 심근혈류가 정상이었다. 4명의 환자에서 전기생리학적검사 및 전극도자 절제술을 시행하였다. 9명의 가역적 그리고 1명의 비가역적 관류결손이 관찰되었고. 범위는 소에서 대까지 강도는 경도에서 중등도까지 나왔다. 부전도로의 위치가 우외측인 1명은 관류결손이 없었으나, 그 외의 환자들은 다양한 양상을 보였다. 부전도로의 위치가 좌외측인 환자중 1명에 대해 전극도자 절제술을 시행하였고 6주후에 SPECT를 한 결과 시술 전에 있던 관류결손의 범위가 현저하게 감소하였다. 결론: WPW환자에서 심근관류결손은 다양한 범위, 강도 및 위치를 가진다. 거의 대부분의 환자에서 비정상적인 관류결손이 나타났으나, SPECT 소견으로 부전도로의 위치를 특이적으로 예측하기는 어려웠다. 그러므로 WPW증후군 환자에서 심근관류 SPECT의 결과를 주의 깊게 해석해야 한다.

It is well known that multipoint and computerized intraoperative mapping systems improve the results of surgery for Wolff-Parkinson-White syndrome and show tremendous potential for opening an entirely new era of surgical intervention for the more common and lethal types of supraventricular tachyarrhythmias such as atrial flutter and atrial fibrillation. In addition, the ability to map and ablate the sometimes fleeting automatic atrial tachycardia is greatly enhanced by computerized mapping systems. In this study, we have developed 64 channel computerized data analysis system using microcomputer (Macintosh ${II}_{x}$) for basic research of electrophysiology and electrical propagation. The bipolar electrogram information is acquired from 64 cardiac sites simultaneously at a sampling rate of 1 ksampls/sec with continuous and total data storage of up to 30 seconds. When the reference electrogram is selected and reference point is picked up, delay time from the reference point is displayed on two dimensional diagram of the heart. System design permits easy expansion to almost 256 simultaneous sites. this system is expected to enable us to study pathophysiology of cardiac arrhythmia and to improve the result of diagnosis and surgical treatment for cardiac arrhythmia.

Purpose: We evaluated caregivers' understanding of patients' diseases and disuse syndrome, the understanding of exercise and massage related to rehabilitation and the necessity of education about these, the difference in education and realities of the care-giving field, and the extra services needed in the field. Methods: The survey using questionnaires was performed from June 2008 to August 2008 with 220 people participated in caregive education programme in daegu city and area near dagu city. Among the 220 submitted questionnaires, 184 which were faithfully answered were selected and they were analyzed by i-STATistics statistical program. Results: The educational focus of the first and second level caregivers, as defined by the second clause of the 29th article of the Elderly Welfare law, is on basic knowledge of diseases such as dementia, stroke, and depression. However, other diseases are not covered and the information does not include information on decreased function, complications, functional rehabilitating exercises, or preventing disuse syndrome for long term patients. The most common diseases, in order of prevalence, are stroke, dementia, diabetes mellitus, Parkinson disease, arthritis, and geriatric inertness. The general level of awareness about disuse syndrome was low, and patients, while understanding the need for massage and rehabilitative exercise, receive little education about the proper methods and therefore cannot use them. Patients also did not understand how participating in these activities could reduce medical fees, indicating that further education on massage and rehabilitative exercise is needed. Caregivers desired to include positive rehabilitation, massage, and exercise-related services in their services. Finally, differences in caregiver education and reality resulted from a lack of diversity in education. Conclusion: We suggest providing education on disuse atrophy and improving the lack of diversity in the care-giving education system.

MicroRNAs (miRNAs) are small noncoding RNA molecules that negatively regulate gene expression via degradation or translational repression of their target messenger RNAs (mRNAs). Recent studies have clearly demonstrated that miRNAs play critical roles in several biologic processes, including cell cycle, differentiation, cell development, cell growth, and apoptosis and that miRNAs are highly expressed in regulatory T (Treg) cells and a wide range of miRNAs are involved in the regulation of immunity and in the prevention of autoimmunity. It has been increasingly reported that miRNAs are associated with various human diseases like autoimmune disease, skin disease, neurological disease and psychiatric disease. Recently, the identification of miRNAs in skin has added a new dimension in the regulatory network and attracted significant interest in this novel layer of gene regulation. Although miRNA research in the field of dermatology is still relatively new, miRNAs have been the subject of much dermatological interest in skin morphogenesis and in regulating angiogenesis. In addition, miRNAs are moving rapidly center stage as key regulators of neuronal development and function in addition to important contributions to neurodegenerative disorder. Moreover, there is now compelling evidence that dysregulation of miRNA networks is implicated in the development and onset of human neruodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Tourette's syndrome, Down syndrome, depression and schizophrenia. In this review, I briefly summarize the current studies about the roles of miRNAs in various autoimmune diseases, skin diseases, psychoneurological disorders and mental stress.

Purpose: Cardiac radiofrequency catheter ablation procedures using fluoroscopy were performed for the treatment of supraventricular and selected ventricular tachyarrhythmia. Fluoroscopy is used to localize the position of the intracardiac catheter. Fluoroscopically-guided procedures often involve high radiation doses to patient's skin, but the incidence of serious radiation injuries in these patients is rare. We reported two cases of severe postradiation skin injury on the back treated with the V-Y latissimus dorsi musculocutaneous flap. Methods: These two patients underwent radiofrequency catheter ablation under the diagnosis of Woff Parkinson White syndrome (WPW syndrome). They had radiation-induced skin injuries on the subscapular area and these lesions represented chronic ulceration, surrounding induration, hardness, and dyspigmentation. We treated these lesions with complete excision and coverage with V-Y latissimus dorsi musculocutaneous flap. Results: These two patients had no recurrence and no special complications during 20 months and 12 months follow-up periods and were satisfied aesthetically and functionally. Conclusion: V-Y latissimus dorsi musculocutaneous flap obtained better results functionally and aesthetically compared with conservative management and skin graft in severe radiation-induced skin injuries after cardiac radiofrequency catheter ablation procedure.

Essential tremor(ET) is the most common movement disorder however there has been little agreement in the neurologic literature regarding diagnostic criteria for ET. Familial ET is an autosomal dominant disorder presenting as an isolated postural tremor. The main feature of ET is postural tremor of the arms with later involvement of the head, voice, or legs. In previous studies, it was reported that ET susceptibility was inherited in an autosomal dominant inheritance. As with previous results, it would suggest that ET might be associated with defect of mitochondrial or nuclear DNA. Recent studies are focusing molecular genetic detection of movement disorders, such as essential tremor and restless legs syndrome. Parkinson's disease(PD) is a neurodegenerative disease involving mainly the loss of dopaminergic neurons in substantia nigra by several factors. The cause of dopaminergic cell death is unknown. Recently, it has been suggested that Parkinson's disease many result from mitochondrial dysfunction. The authors have analysed mitochondrial DNA(mtDNA) from the blood cell of PD and ET patients via long and accurate polymerase chain reaction(LA PCR). Blood samples were collected from 9 PD and 9 ET patients. Total DNA was extracted twice with phenol followed by chloroform : isoamylalcohol. For the analysis of mtDNA, LA PCR was performed by mitochondrial specific primers. With LA PCR, 1/3 16s rRNA~1/3 ATPase 6/8 and COI~3/4 ND5 regions were observed in different patterns. But, in the COI~1/3 ATPase 6/8 region, the data of PCR were observed in same pattern. This study supports the data that ET and PD are genentic disorders with deficiency of mitochondrial DNA multicomplexes.
