Syringoadenoma papilliferum occurs as a solitary lesion appearing usually on the scalp. It's origin is not definitely known, and about one-third of cases are associted with nevus sebaseous. We describe a case of syringoadenoma papillferum associated with nevus sebaseous in a 29 year-old female who had developed bean sized verrucotic nodules on the Rt. temporal area of the scalp since 6 years after removal of nevus sebaceous. Histopathologic findings showed hyperkeratosis, acanthosis and villi that projected into a cystic lumen. And the villi were surrounded by two cell layers.

배경: 본 연구는 SCL-90-R에서 9개 증상차원의 요인구조가 어떻게 나타나는지를 알아보는 데 목적이 있다. 방법: SAS 프로그램을 이용하여 정신과적 장애로 진단받은 환자 188명이 수행한 SCL-90-R 자료의 요인구조를 분석하였다. 결과: 요인분석 결과 SCL-90-R의 9개 증상차원은 단일요인으로 나타났다. 결론: SCL-90-R의 요인분석 결과 단일 요인 모형이 탐색되었다. 추후 연구에서는 SCL-90-R의 9개 척도에 대한 확인적 요인분석이 필요할 것으로 생각된다. Background: To find of this study was to find exploratory factor analysis of the nine scales of the Symptom Checklist-90-Revision(SCL-90-R). Methods: This study was investigated the factor structures of nine scales of the SCL-90-R in 188 patients with psychiatric disorders using SAS 8.02 software. Results: The factor structure showed that the factor structures of nine scales of the SCL-90-R had one factor. Conclusion: The factor structures showed that the factor structures of the SCL-90-R had one factor. Further research is nedeed about confirmatory factor analysis of the nine scales of the SCL-90-R.

Booming Noise of a Automotive can be divided in Air Borne Noise and Structure Borne Noise. In this study, Booming Noise is reduced by the vector Synthesis method. The vibration that transferred by the engine is managed. The car that by the used model is composed of Mount system supported to three point with 2000 cc 14 engine FR vehicle. The vibration that is transmitted from propeller sharft and Differential Gear to Sub Frame and Suspention effect Booming Noise. but, The vibration that generated by the Mount has Booming Noise more than it. So, We research that sound generated by the Mount and reduce that Booming Noise used the Dynamic Damper. The Booming. Noise by the vector Synthesis. is reduced in 2000 ~ 4000 rpm front of vehicle. We know that Booming Noise is reduced into hoped for rpm by the vector Synthesis.

As a part of environmental pollution prevention and resources recycling, the regeneration of waste tire has been largely contributed to national industry. But, the worker has been evaded this regeneration process by reason of the best mischievous process condition among 3D industries.So, the first, the process condition of regeneratingwaste tire was analyzed. The second, the equipment or system was developed for the improvement of working strength and environment. The last, researchers intend to solve these problems

In this study, the researches classifying the natural flaws in welding parts are performed using the signal pattern classification method. For this purpose 500MHz storage digital oscilloscope including FFT function and enveloped waveform generator are used and the signal pattern recognition procedure is made up the digital signal processing, feature extraction, feature selection and classifier design. Specially it is composed with and discussed using the distance classifier is based in euclidean distance the empirical Bayesian classifier. In feature extracting, it is performed using the class-mean scatter criteria. And the signal Pattern classification method is applied to the signal pattern recognition problems of natural flaw that is porosity inclusion, slag inclusion, lack of penetration, lack of fusion. center crack, side crack, toe crack. root crack as the planar and volumetric flaw classification problem. According to this results, if appropriately learned the neural network classifier is better acquire the recognition rate of 86.31% above through it is different a little according to domain extracting the feature and the classifier

The purpose of this welding process of the exclusive welding-machine using welding torch-rotation type is to develop a mechanism which can solve the problem of twisting of welding wires and cables. The technique was developed by revising the revising the torch position and smooth controling of both the normal and reverse rotation. Some of the advantages of using the torch-rotation type apply to the work-rotation technique are the practical uses of increased work space and link work with the factory automation system. Do apply the welding process, I designed and made a special unit so called torch part in order to solve the problems of kinematical. And I made a control panel which can manipulate the progress of the entire process at the work shop. Even if it will be applied to another kind of axle casing's welding work, this process can be utilized if other sizes of the fixed pin and work part is produced and changed. The development of this exclusive welding-machine could reduce the manpower of skilled welding labor and increase productivity and better quality product in comparison to the handmade product.

BRS는 인간의 잠재능력을 적극적으로 계발 · 활용하여 임의의 시료에 대한 미지 (未知)의 생체정보 (Bio-Information)를 편리하게 분석할 수 있는 효과적이고 경제적인 분석장비이다. 그러나 BRS와 관련된 분석방법 자체의 정확도에 대한 연구는 충분하게 이루어지지 않고 있다. 그래서 BRS 분석방법의 정확도를 과학적으로 확인해보기 위해서 본 연구를 진행했다 실험결과, BRS에 의한 생체정보 분석방법 의 정확도는 측정자의 숙련정도에 따라 다르지만 고급 측정자의 경우에는 95% 이상의 높은 확률로 표준시료의 생체정보를 정확하게 분석할 수 있으며, 측정자의 분석능력이 떨어지는 경우에는 여러 명의 측 정자를 대상으로 비교검토(Cross-Check) 방식으로 실험을 보완하면 90% 이상의 정확도를 확보할 수 있었다. BRS is a sort of analysis-instrument which help to estimate some Bio-Information for a sample conveniently and effectively But, for lack of the study to verify the confidence-degree of the Bio-Information analysis method related to BRS, the availability of the method is not known clearly yet, It was the reason that made authors perform this study And It was possible to arrive at the following two conclusions I though the confidence-degree of the Bio-Information analysis method ny BRS was different according to the degree of the expertness of a person using the instrument in the case of the very skillful expert, the confidence-degree for the standard sample used in this study was reached to 95% up 2 In the general case, to improve of the confidence-degree of the Bio-Information analysis method by BRS, the cross-check method by the several measuring person can be introduced.
