聽覺障碍兒에 關한 臨床聽覺學的 硏究 : Prevalence, Causative Diseases and Audibility

李圭植 韓社大學特殊敎育硏究所 1980 特殊敎育硏究 Vol.8 No.-

This investigation was concerned with the prevalence, the causes of hearing los and audibility of hearing impaired children. Total number of subjects was 110,387 comprising 79,532 students from urban area and 30,855 from rural areas. The subjects, 79,532 students from 34 schools selected in urban area were audiologicaly examed:-51,593 students in ten elementary schools: 15,152, in ten middle schools; and 12,789, in 14 high schools-, and 30,855 students from 50 schools in the rural:-16,542 students in 27 elementary schools; 7,902, in 14 middle schools; and 6,411, in nine high schools. This survey and analizing of the data have been continued for a period of five years since 1975. Prevalence of Hearing Impairment The prevalence of the students having hearing loss over 27dB should five per 1,000 students. Those who having hearing loss over 41dB requiring special class showed 1.5 per 1,000. And 0.23 out of 1,000 students fell into a category of a 71dB hearing loss requiring special education in a deaf school. The cases with hearing loss were distributed to five categories as follows in severity according to the classification of the International Standard Organization (I. S. O.) : 0.35% mildly impaired, 0.09% moderately impaired, 0.04% moderate severely impaired, 0.02% severely impaired, and 0.003% extremely impaired. Otherwise they were pathologically classified into three types being conductive impairment, sensory-neural impairment and mixed impairment : the rates were 0.34%, 0.07% and 0.1% respectively.

컴퓨터 비젼시스템을 이용한 평면상에 있는 점위치 결정에 관한 연구

장완식,이규태,김재확 朝鮮大學校 機械技術硏究所 1998 機械技術硏究 Vol.1 No.1

비젼 시스템이 개발되기 시작한 것은 1973년에 PDP-10 컴퓨터를 이용한 물펌프 조립이 시각정보를 이용하여 Stanford 연구진에 의해 수행되었다. 그 이후, 비젼 시스템이나 비젼센서가 활용되는 예로는 용접, 운반, 조립, 측정 검사 등이 있으나, 지능로봇중의 한 분야로 로봇 비젼시스템을 생산현장에 적용하는 경우가 늘고 있다. 비젼을 사용하면 매니퓰레이터가 우주 공간이나 수중등 실제 공간에서 그 위치와 방향이 불확실하게 알려져 있을지라도 작업을 수행할 수 있다. 따라서, 로봇 비젼 시스템은 주로 대상물의 위치가 불규칙하거나 기구학적으로 위치결정을 하기 어려운 작업의 자동화에 적용이 널리 확대될 것으로 예상된다. (1)(2)(6)(7)(8) 로봇에 비젼을 적용할 때 실제 공간은 3차원인 반면에 비젼 정보는 2차원이기 때문에 카메라 좌표계와 매니퓰레이터나 실제 공간 좌표계를 일치시켜 주는 보정은 가장 중요한 요소중의 하나이다. 카메라 교체시나 카메라 위치 수정시에도 필히 보정을 다시 시켜줄 필요가 있다. 만약 보정이 정확하게 되어 있지 않으면 매니퓰레이터의 경우 올바른 제어를 하지 못할 우려가 있고, 또한 부적절한 보정계수 산출로 인한 목표점의 추정이 어긋나게 된다.(3) 이리하여 본 연구는 이러한 문제점을 해결하기 위하여 6개의 시각 매개변수를 이용한 새로운 비젼 시스템 모델을 제시하고, 2차원 평면 점위치 결정 실험을 통하여 제시한 비젼 모델의 적합성을 검증한다. 본 실험에서 사용되는 비젼 시스템은 두 대의 고정된 카메라를 작업공간에 설치하여 이용한다. 본 연구의 제한 조건은 평면상에 존재하는 알려지지 않은 물체의 위치 결정을 위해서는 그 물체 주위에 알려진 몇 개의 좌표값이 존재해야 한다는 것이고, 본 연구에서는 알려지지않은 점으로부터 위치가 알려진 점과의 거리에 대한 상관관계, 위치가 알려진 점의 개수에 대한 상관관계 및 결정된 물체 위치의 정확성을 실험을 통하여 검증하고자 한다. This paper presents the application of computer vision for the purpose of determining the position of the unknown point in the plane. The presented control method is to estimate the six view parameters representing the relationship between the image plane coordinates and the real physical coordinates. The estimation of six parameters is indispensable for transforming the 2-dimensional camera coordinates to the 3-dimensional spatial coordinates. Then, the position of unknown point is estimated based on the estimated parameters depending on the cameras. The suitability of this control scheme is demonstrated experimentally by determining position of the unknown point in the plane.

기본 물리 단위에 대한 고찰

A fundamental standard has two principal characteristic : it is accessible and it is invariable. In order to satisfy this condition, the fundamental standard has been required to change its former definition, The meter is now defined in terms of the speed of light in vacuum; the kilogram, the only SI unit still defined by a physical artifact, is the mass of the international prototype of the kilogram; and the second is defined in terms of the transition between the two hyperfine levels of the ground state of cesium-133, For the definition of the SI electrical units, the Ampere is replaced by the volt and the Ohm, The fundamental standards for the volt and the ohm have been based on the Josephson effect and quantum Hall effect respec-tively. These new standards are introduced to improve the accessiblity and invariance.

We reriewed the stability of the scalar fields in 2 dimensional and the vortex-like solutions in 3 dimensional. Also we explain the reason of the existence of the magnetic monopole in Non-Ablian theory and discuss the instanton which has a finite energy in the Euclidean Space. In addition to there, we give a rough explanation for the Chern-Simon theory.

This study was conducted to investigate the biomechanical characteristics of the gait pattern in an amputee for the purpose of improving the proper gait posture and designing the prosthetic. The subjects were six males amputees and one normal person. The ground reaction force was measured using AMTI force platform. The conclusions were as follows; 1. In case of amputee group, the ground reaction force was revealed in specific figure according to position in which they used the prosthetic, whereas in case of normal person the ground reaction force was revealed in the figure of two humps in regard of vertical axis. 2. In case of amputee group, the ground reaction force in time between fight foot contact and left foot contact was deviated from a figure of rectangle, whereas in case of normal person the ground reaction force was revealed in the figure of rectangle. 3. In case of amputee group, the ground reaction force referred to both feet angle point of view was revealed in irregular figure, whereas in case of normal person the ground reaction force was revealed about 47。

This study was carried out to investigate the storage conditions and methods required for commercializaion of Jeung-Pyon. The storage characteristics of Jeung-Pyon were examined with Universal Testing Machine (UTM. Instron model 1000) for textural properties during storage of tinder the conditions such as sealing, nonsealing, and temperatures. The differences in storage characteristics on the different varieties and years of rices were not shown. When the Jeung-Pyon was lost it's quality as a commercial product, the measured value of UTM was increased as hardness 0.74㎏ to 1.0㎏, gumminess 0.23㎏ to 0.59㎏, chewiness 6㎏.mm to 18㎏.mm, but decreased in adhesiveness 0.65㎏.mm to 0.40㎏.mm, cohesiveness 0.61 to 0.34, springiness 41㎜ to 32㎜. The nonsealed Jeung-Pyon was lost it's quality for storing at room temperature because of the case-hardening after 2 days. In the case of sealed Jeung-Pyon, the case-hardening phenomena by the evaporation of moisture was not occured, therefore it was a significant factor for an extension in sealed Jeung-Pyon. The shelf-life of sealed Jeung-Pyon was 20 days and 5 days respectively during storage at -20℃ and 20℃ The sealed Jeung-Pyon stored at 5℃ was lost it's quality, in consideration of cold chain this temperature was suitable for retrogradation of starch. The Jeung-Pyon sealed with air and mosture proof packaging material stored at the accelerated condition as 92% R.H. and 35℃ lost it's quality within two or three days.
