  • Magnetic resonance imaging (MRI) is a standard imaging modality for diagnosing spinal stenosis, which is a common degenerative disorder in the elderly population. Standardized interpretation of spinal MRI for diagnosing and grading the severity of spinal stenosis is necessary to ensure correct communication with clinicians and to conduct clinical research. In this review, we revisit the Lee grading system for central canal and neural foraminal stenosis of the cervical and lumbar spine, which are based on the pathophysiology and radiologic findings of spinal stenosis.

  • The Purpose of this study Gerber company AM-300 system of the automatic system of Producing the original form the automatic system of Producing the original form of "Jogori(a Korean Jacket)' and Grading by the usage of computers and find out its efficiency. In the result, the auther has found out the following facts and became confident on the facts; The AM-300 program of the automatic system enabled to produce the original form of 'Jogori' and Grading fitting in a short time and definately, and which indicated that the automatically producing system of the original form of 'Jorgori' and Granding is efficient. Even in the aspect of education, it has been acknowledged that there is necessity of using computers, the accumulation of techincs and technology based on traditions by cultivating professional designers, and computerization so that the composition of 'Hanbok' (Korean clothes) should be rational and scientific. In addition, advertisement and education on the traditionalism and superiority of 'Hanblk' are indispensable and absolutely necessary. Also, to succeed folk costumes rightly, the usage of computers is thought to be a way to effectiveness. So far in the study, only the automatic system of producing the original form of 'Jogori' and Grading through computers is emphasized on, however in the future, such an automatic system should be continuously supplemented, studied on and developed even in other various fields such as in pattern making, design, products planning, etc..

  • Objectives The objective and universal grading system for the facial nerve palsy is needed to the objectification of treatment in Oriental medicine. In this study, the facial nerve palsy grading was developed with combination of image processing technique and Nottingham scale. Methods The developed system is composed of measurement part, image processing part, facial nerve palsy evaluation part, and display part. With the video data recorded by webcam at measurement part, the positions of marker were measured at image processing part. In evaluation part, Nottingham scales were calculated in four different facial expressions with measured marker position. The video of facial movement, time history of marker position, and Nottingham scale were displayed in display part. Results & Conclusion The developed system was applied to a normal subject and a abnormal subject with facial nerve palsy. The left-right difference of Nottingham scores was large in the abnormal compared with the normal. In normal case, the change of the length between supraorbital point and infraorbital point was larger than that of the length between lateral canthus and angle of mouth. The abnormal case showed an opposite result. The developed system showed the possibilities of the objective and universal grading system for the facial nerve palsy.

  • 자동차 운전면허 시험에서 객관적인 평가가 중요하다. 특히 도로 주행시험은 실제 도로에서 운전능력, 규칙준수, 상황판단능력 등을 종합적으로 시험하는 것이다. 이를 위하여 본 논문에서는 GPS와 센서 데이터 및 기기조작 정보를 활용하여 운전면허 시험의 자동채점시스템을 제안한다. 자동채점 시스템은 차량탑재장치, 채점용단말, 데이터 제어장치, 데이터 저장 및 처리를 위한 서버로 구성되어 있다. 차량탑재장치는 차량에 설치된 센서 데이터를 수집한다. 채점 단말은 차량탑재장치로부터 받은 데이터를 활용하여 기준에 따라 자동채점 한다. 또한 이동 중에 GPS 오차로 인하여 차량이 도로를 벗어나 표현되므로 지도매칭 기법과 경로이탈 및 복귀 알고리즘을 적용하였다. 이 시스템은 기존 시험 채점 방식과 달리 자동 채점이 가능하며, 시험 결과에서 정확한 차량위치 표시와 GPS 음영지역을 벗어났을 때 10초 이내로 경로 복귀를 하였다. 이 시스템은 도로 주행 교육에도 활용될 수 있을 것으로 기대된다.

  • 컴퓨터를 활용한 강의 지원시스템은 오래전부터 개발되어 사용되고 있으나, 완벽한 강의지원이란 쉬운 일이 아니다. 따라서 본 시스템은 대학 강의에 적합한 온라인 강의지원 관리 시스템을 개발하는데 그 목적이 있다. 본 개발 시스템은 대학에서의 데이터베이스과목 관리에 목표를 두고 주로 시험과 채점관리에 초점을 맞추어 개발되었다. 강의관리를 위한 출석관리, 리포트관리, 퀴즈와 같은 수시시험관리 및 정규(중간, 기말)고사의 실시 및 채점을 주목적으로 하였다. 시험의 경우 객관식, 주관식, 단답식 그리고 SQL로 나누어 개발되었다. 특히 SQL의 경우 구분분석을 통해 채점할 수 있는 시스템을 개발함으로서 보다 효과적인 채점관리에 주력하였다. 주관식 및 단답형의 경우는 수작업을 통한 채점방식을 사용하였으며, 이 모든 과정을 학생 스스로 확인할 수 있도록 하여 채점과 관련한 문제를 해소하도록 하였다.

  • An on-line real time grading and sorting system for dried oak mushrooms was developed for on-site application. Quality grades of the mushrooms were determined according to an industrial specification. Three dimensional visual quality features were used for the grading. A progressive color computer vision system with white LED illumination was implemented to develop an algorithm to extract external quality patterns of the dried oak mushrooms. Cap (top) and gil (stem) surface images were acquired sequentially and side image was obtained using mirror. Algorithms for extracting size, roundness, pattern and color of the cap, thickness, color of the gil and amount of rolled edge of the dried mushroom were developed. Utilizing those quality factors normal and abnormal ones were classified and normal mushrooms were further classified into 30 different grades. The sorting device was developed using microprocessor controlled electro-pneumatic system with stainless buckets. Grading accuracy was around 97% and processing time was 0.4 s in average.

  • The necessity of remodeling performance grading system is getting increased for the systematic management of existing housing stock, providing the resident's right to know and promoting the remodeling projects. A quantitative and objective evaluation method that has reflected the characteristics of remodeling must be developed because there is an aspect of having difficulty of assessment by an ordinary person as remodeling performance contains specialized details while the difficulty of applying the criteria of new buildings in terms of assessment items, criteria and methods. Accordingly, this study sets the goal as setting up the development objectives of performance grading system that has considered the remodeling characteristics. This study has analyzed the various assessment systems related to the domestic apartments as well as setting up the organization system of the remodeling performance grading system, perspectives of performance assessment and scope of assessment through literature, etc. It has also established the principles for setting up the assessment items of remodeling performance grade to present the directions for setting up assessment items and criteria.

  • Objectives : This study was to observe clinical application of auto-microneedle therapy system (AMTS) in patients with peripheral facial paralysis. Methods : 27 peripheral facial paralysis patients were observed after taking AMTS at Facial Palsy Center, Kyung Hee University Oriental Medicine Hospital from March 1, 2011 to January 9, 2012. We assessed the symptoms of facial paralysis with Yanagihara unweighted grading system, Sunnybrook facial grading system(SBGS) and facial disability index(FDI), and observed adverse events and total safety of the treatment. Results : The scores of facial palsy scales increased after AMTS in Yanagihara grading system and Sunnybrook facial grading system. AMTS-related adverse events were mild pain(5.9%) and fatigue(3.5%), which needed no extra treatment. The total safety evaluation was between 'safe' and 'nearly safe' level. There were no other serious adverse events. In addition, patients were satisfied with subjective improvement including facial tingling and numbness. Conclusions : AMTS can be applied as an adjunctive treatment for patients with peripheral facial paralysis due to its safety and clinical usefulness. It is easier to stimulate wide skin area in a short time. Further clinical research is required to investigate the effectiveness of ATMS in a more rigorous RCTs.
