No-tillage cultivation of corn is a method to be recommended at the places where soil erosion is considerable. This experiment was conducted to investigate the responses of corn hybrids under conventional and no-tillage cultivations. The field used for this experiment was the site which corn was grown in previous year. Averge grain yield of nine corn hybrids under no-tillage was similar to that of conventional tillage, however, the responses among hybrids were quite different each other. Hybrid NC246 x Ga209 and Kwanganok significantly increased under no-tillage, but CIM A21 x Ga209 and P3160 decreased significantly. Days to tasseling were similar in both cultivations. Plant and ear heights were higher in conventional tillage. Yield components of conventional tillage were higher than those in no-tillage, also indicated higher variations among hybrids.

李鍾赫,安樂善 忠州大學校 1996 한국교통대학교 논문집 Vol.31 No.1

In this paper, I have studied on the harmonic drive compared with actual profile. I have obtained the result as follows:The analysis carried out in a plane mechanism. From the analysis of the motion of the rigid gear and the flexible gear, the shapes of the rolling contact plates which move together with each tooth are derived, assuming that the toohh of the flexible gear is rigid although the tooth groove is flexible and that the pitch if the tiith on the unstrechable neutral line of the flexible gear is contact. 1. Harmonic drive could obtain high speed ratio, high torque capacity and high reduction ratio. 2. Harmonic drive has largely used as a gool gearingtooth form. 3. We can obtain a good proper shift coefficiented by strength analysis.

이용호,권혁찬,김진목,이상길,임청무,박용기,박종철 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

We report on the design, fabrication and performances of a low-noise Nb SQUID sensor for neuromagnetic measurements. The main features of the developed sensor are i) large flux-to-voltage transfer, making the SQUID readout electronics simple, and ii) use of the integrated planar pickup coil to eliminate the environmental magnetic field noises. The magnetic field noise of the developed SQUID sensor is below 5 fT/√Hz at 100 Hz, which is low enough to be used in neuromagnetic measurements.

Renal transplantation is the treatment of choice in management of patients with end stage renal disease. We have experienced the 2 cases of renal transplantation with complications successfully managed by medical treatment. One case of erythrocytosis and another case of severe, recurrent acute graft rejection were observed respectively and recovered by medical management. In all cases, triple immunosuppressive agents(prednisolone, azathioprine and cyclosporine) was administerd. In the first case, 54 days later after transplantation, the hematocrit of the patient has risen to 57%. With 2 trials of phlebotomy, hematocrit became to 48% 141 days later and persisted below the level of 48% after that time. In the second case, during 2 weeks after operation, there were 2 episodes of severe, acute rejections. With aggressive steroid pulse therapy, these rejection episodes were managed without renal dysfunction. We report the 2 cases of renal transplantation with complications successfully managed by medical treatment.

The purpose of this study was to investigate the effect of modified constraint induced movement therapy(mCIMT) on activities of daily living(ADL) and quality of life(QOL) for patients with stroke. Methods : Thirty subjects were randomly allocated into two groups: mCIMT, an experimental group(n=15) and traditional occupational therapy group, a control group(n=15). Both groups also received the usual occupational therapy after the first intervention. The ADL performance ability of both groups was assessed using Motor Activity Log(MAL) and QOL was assessed by Stroke Specific Quality of Life(SS-QOL). Results : ADL performance ability had a meaningful increase statistically for both groups. QOL also had a meaningful increase statistically for both groups. ADL performance ability showed statistically significant correlations with QOL. Conclusion : It was found that carrying out mCIMT with occupational therapy has an effect on ADL performance ability and QOL of patients with stroke. It was also found that ADL performance ability influences QOL.

建設工事 監理制度의 改善方案에 관한 硏究

李培浩,李梁圭,朴鐘奕 중앙대학교 기술과학연구소 1989 기술과학연구소 논문집 Vol.19 No.-

海外工事에서는 技術用役業者에 의한 工事監理制度가 一般的으로 運營되고 있으며 우리나라에서는 最近에 정부工事에 監理制度가 導入되어 部分的으로 運營되고는 있으나 建設工事의 運營에 問題點이 있음을 알 수 있다. 즉 監理豫算의 確保 및 執行에 따른 問題 資格監理要員의 配置. 監理要員의 業務上의 倫理 監理業務의 運營등이다. 보다 나은 監理制度가 되기 위해서는 建設工事 監理制度가 적절한 자격을 갖추도록 하는 중요한 정책이 있어야 한다.建設工事의 진보적인 기능과 개선된 품질관리를 위하여 監理制度는 제도화 하는것이 필요로 한다. 보통 정부난 지방자치단체에서 지시한 일부 建設工事는 품질관리와 특성이 요구된다. 監理制度의 執行은 확립되지 않은 監理用役회사로 원치않은 현상을 초래 할 수도 있다. 그런 환경때문에 대부분의 用役회서는 아마도 그 특성이라는 결핍을 가져올 수 있다. 왜소한 확립성이 없는 用役회사 역시 다른 문제점을 초래한다. 따라서 정부는 재정적으로 그리고 제도적으로 監理用役회사를 보조해서 촉진 시켜야 한다. 契約制度의 고용도입과 적절한 지불은 시급히 요망된다. 적절한 지불규정은 법률화 하는것이 감리제도 개선의 선행방안이다. Technology consultant service agents normally manage to control construction supervision in overseas constructions. Recently in domestic constructions the supervision system is partially introduced to government-operated building. But there are still a lot of problems in the management of constructions. That is, for normal supervision the procurement and execution of budget, the replacement and functional ethics of qualified supervisors are difficult problems. For a better perspective of supervision the following are important policies that should be designed to help construction supervision get its proper status. To institutionalize the supervision system for both advanced function and improved quality control of constructions is necessary. Some constructions above average ordered by central or provincial governments need such quality control and speciality. The execution of supervision system may bring unwatned phenomena of irregular circumstances most consultant companies. Under such circumstances most consultant companies probably fall into the lack of speciality. The smallness of such irregular consultant companies is also another problem. Thus the government should support and promote supervision consultant companies financially and institutionally. The introduction of employment of contract system and appropriate payment is urgently needed. To legislate suitable payment regulations is prerequisite to the improvement of supervision system.

현대 사회에 이르러 생활 환경의 향상과 기술의 발달로 복지에 대한 관심이 높아졌으나 국내의 장애인에 대한 복지 시설은 아직 미비한 수준이다. 보도의 점자 블록이나 신호등의 보행 음향 외에 시각 장애인이 실외 활동을 하기 위한 안내 시설이 거의 없어 많은 불편을 초래한다. 따라서 시각장애인을 위한 안전하고 편안한 보행을 위한 보조장치가 필요하다. 본 연구에서는 시각장애인에게 보다 안전하고 편리한 보행보조 수단을 제공하기 위하여 계단 승월이 가능한 유도로봇을 개발하였으며, 이의 시스템은 실외에서 장시간사용이 가능하도록 저전력 구동이 가능한 이동로봇 제어부, 외부 위치 정보를 GPS에 의해 유도가 가능하도록 자기위치추정시스템과 계단 승월이 가능한 메카니즘부로 구성하였다. 제안된 시각장애인 유도로봇의 구동을 위하여 이동 로봇 구동 및 운용 소프트웨어를 개발하였으며, 초음파 센서 어레이를 이용한 장애물 인식을 통한 스테레오 음성 유도 알고리즘, 관성항법시스템을 이용한 주행 경로 보정 시스템 및 알고리즘, 시각 장애인 유도를 위한 점자 보도 블록 인식 기법을 개발하였다. 자기위치추정시스템에서는 자기위치 추적 시스템 H/W와 사용자 인터페이스 개발로서 DGPS수신 모듈과 점자 입력기 및 인터페이스 기법을 개발하였으며, 계단 승월을 위한 유도로봇 메카니즘으로 유성 차륜 방식을 이용하여 이동 메커니즘을 설계하였다. Interest about welfare by upgrade of living environment and development of technology to reach in modern society but welfare facilities about disabled person are unprepared level yet. It causes many discomforts because there is seldom guidance equipment that the visually impaired except Braillewriter type block or walk sound of signal lamp does outdoor activity. Therefore, we need auxiliary equipment for more safe and well walk for the visually impaired. The purpose of this study is to develop a stair-climbing guide robot as auxiliary equipment for the visually impaired. We developed a control part with low-power usable for many long hours outside the door, self-localization system guiding the robot by using the GPS of localization information and mechanism part with an ability of climbing stairs. We developed mobile robot driving and operating software to operate the guidance robot for the visually impaired such as obstacle detection with ultrasonic sensor array, obstacle avoidance through the sound imaging method, position calibration using INS (Initial Navigation System) and detection of braille blocks. In self-localization system, we developed a self-localization H/W and user interface, we adapted DGPS receiver module and suggested a method to interface for braille keypad. For ability of climbing stairs, we constructed wheel mechanism of a guide robot using planetary type.
