Hip joint is one of the most deeply located joint in human body. Moreover, most clinical symptoms of various hip diseases are vague and confusing. In these reasons, the imaging modalities of hip have been extensively studied and developed. From a plain radiograph to more complex MR arthrography, various techniques are now available. In this brief review, the long and short of imaging modalities and clinical examples of common hip diseases will be introduced. The most important significance of diagnostic imaging is its clinical relevance. It is because when we know the characteristics of the imaging modalities and the disease itself, the optimal approach to a patient can be achieved, but when we do not know, the expensive images can only be a meaningless picture.

Tuberous sclerosis is reported rarely and is associated with systemic lesions including central nervous system, skin, heart, eye and kidney. Approximately 5-15% of individuals with tuberous sclerosis will develope brain neoplasia, almost invariably subependymal giant-cell astrocytoma (SGCA). We experienced a case of SGCA with tuberous sclerosis operated by the transcallosal approach and report with literature review.

Lately, result that the myopathy occurrence rate such as muscle disease and brain apoplexy by the tribe of momentum by aging society and information-oriented society, imbecility, Parkinson's disease, motor nerve disease is increasing rapidly and investigates the occurrence rate, was expose that increased more than man case 2 double and man and woman of mortality increases by about 50% with Parkinson's disease and motor nerve disease. <중략> Is going to apply to myopathy patient of other disease if supplement system hereafter, and this research tried to study rain standardization special quality and approach producing poetic theme width directly.

In this abstract, introduces a system that enables communication by tracking the pupils of Lou Gehrig's disease patients who are unable to move their bodies. Face and eye pupil tracking perform using OpenCV, and eye movement recognition and character selection by eye movement is obtained using Python. In this paper, you will use the webcams, track your eyes, determine eye movements based on the coordinates of your pupils, and print characters that meet your preferences. It can easily output text messages using Bluetooth.

We have experienced five cases of atrial septal defect closure under complete port access using the da Vinci system. We used only six 8∼12 mm ports without thoracotomy or sternotomy for operation.

We propose the various Telemedicine applications using collaborative PACS environment. Traditionally, almost all medical images have been printed on radiological films. These films are expensive to produce and easy to misplace and usually only one copy exists, thus limiting the number of persons who have simultaneous access to the images. But the merit of this system including PACS(Picture Archiving and Communications System ) is very many which are small depository, low maintenance expense, good efficience(storage, speed) and good flexibility but the development costs is higher. This research has been done creating multimedia-based Telemedicine system for home PCs in network environment. Most of Telemedicine used hardware and exclusive line of high cost as CATV broadcasting technique. But this system will contribute to change the Home-PC for better use of collaborations among doctor and patients through various modes of interactions in cyberspace.

The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. In particular, we address the communication security issues of access sharing of health information resources in the ubiquitous healthcare environment. The proposed scheme resolves the sender and data authentication problem in information systems and group communications. We propose a novel key management scheme for generating and distributing cryptographic keys to constituent users to provide form of data encryption method for certain types of data concerning resource constraints for secure communications in the ubiquitous healthcare domains.

Purpose: There are various approaches for open reduction surgery for orbitozygomatic fractures. After the incisions are performed, patients might have various complications. In this point of view, we conducted a retrospective study of the usability of infraorbital incision on elderly patients, generally more vulnerable to scleral show and ectropion. Methods: In this study, 20 patients who are relatively more vulnerable to scleral show and ectropion through snap-back test having infraorbital incision were reviewed. We monitored the duration of the surgery, and complications resulted from the incision. We evaluated the scars with the researcher's observations and with the patient's level of satisfaction on a scale of 1 to 5. Results: On average, 5 minutes was spent between the skin incision and the fracture exposure. No case of scleral show and ectropion occurred. One year follow-up observation revealed 4 cases of visible scars, 9 cases of barely visible scars, and 7 cases of invisible scars. The subjective satisfaction level of the patients' scar is an average of 4.0. Conclusion: Infraorbital incision has many advantages. First, it can reduce the complications such as scleral show and ectropion. Second, it can shorten the operation time. Third, it can diminish incision-related scars.

Congenital malformation is observed in about 2-5% of newborns and is a leading cause of infant mortality. The prognosis of malformation is dictated mainly by proper treatment followed by correct diagnosis at an early age. In practice, etiological consideration and classification of a malformation is critical for diagnosis. Malformations can be classified as belonged to minor or major anomaly. It is clinically important to clarify the pathogenesis of the anomalies among malformation, deformation, disruption, and dysruption. Genetic counseling aids this process by helping patients or family members understand and the nature of the malformation and risk assessment.

We report our experience with a case of urethrolysis using a transvaginal suprameatal approach without lateral perforation of the urethropelvic ligament. A 43-year-old woman suffered from voiding difficulties such as hesitancy, frequency, urgency, decreased urinary flow, residual urine sensation after Marshall-Marchetti-Krantz operation concurrent with hysterectomy. The results of multidisciplinary work-ups of urethral obstruction such as history, vaginal examination, voiding cystourethrography, urodynamic study, showed that she had urethral obstruction due to a previous operation. Since clean intermittent catheterization and alpha-blocker therapy did not improve her symptoms, suprameatal transvaginal urethrolysis was performed to resolve the symptoms. Postoperative follow-up for 5 months showed that the patient remained free from voiding difficulty in their life. We believe that suprameatal transvaginal urethrolysis is worth attempting for urethral obstruction associated with anti-incontinence surgery.
