The sound levels and citizen's responses at urban core of Pusan city in Korea on end and beginning of the year were investigated by the questionnaires and the field measurements. Based on the results, the urban core area was that the sound levels were 70.9dB(??) by mean, 72.8dB(??) by mena. And the frequency range in urban core area were 49.5~66.5dB(??) in day, 50.7~66.5dB(??) in evening. The frequencies with 60dB over were 250~4,000Hz. The citizen's responses for noise were very complaint. The sources of noise were speaklouder sounds of retailers, pedestrian and motorcar etc. The effect of noises were conversation disturbance, mental effect, disturbance of auditory organ, noneffect in order. The citizen's attitudes for life on end and beginning of the year were normal life.

이 연구는 어머니-다운증아의 상호작용을 통한 문제해결과정에서 어머니의 기대성향이 어머니 교수중재의 양과 수준에 미치는 영향과 다운증아의 적목피라미드 문제해결과제에 미치는 효과를 밝히는데 두고 다운증아 어머니의 기대성향에 따른 어머니의 비계화 교수와 아동의 문제해결학습간의 관계를 탐색하고자 하는 것으로,만 6세인 다운증아 남아 3 명과 여아 3명인 전체 6 명 그리고 그 어머니들을 대상으로 하였다. 어머니-아동의 문제해결상호작용과정을 비디오로 촬영하여,어머니의 교수중재는 중재 수준,중재 양,유관 및 비유관 여부를 중심으로 그리고 아동의 문제해결은 성패를 중삼으로 양적 · 질적 분석을 병행 하였다. 연구결과 어머니의 기대성향이 긍정적일수록 아동의 문제해결 성패에 기반하여 중재 양과 중재 수준을 조절하는 유관 중재를 많이 사용하고 문제해결학습에서 부정적 기대성향의 다운증 자녀보다 더 긍정적 학습결과를 보인다. 또한 어머니의 비계화 교수 변인과 자녀의 문제해갤학습 변인사이에는 상호 관련작 양방향성 효과가 있다. The purpose of this study was to examine the relationships between maternal expectancy and maternal use of scaffolded instruction and problem-solving skills of children with Down syndrome. For this purpose, three boys and three girls with Down syndrome whose age were six years old and their mothers participated in this study. The mother-child interaction regarding problem-solving tasks was videotaped and analyzed. The qualitative and quantitative analyses were conducted to find out the condition and quantity of scaffolded instruction used by mothers, and degree of their contingency of the tasks. In addition, it was analyzed whether these children resolved given problems successfully or not. As a result, it was found that the mothers who had more positive expectancy relied more on contingent intervention that regulated the quality and quantity of instructions based on the success or failure of their child' s problem solving tasks, and that their children produced better learning outcome than the children of the mothers who had more negative expectancy. In addition, two-way interrelationships between the scaffolded instruction variable of the mothers and their children ’ s problem-solving learning variable were found.

Visual evoked potentials were elicited by flash in 29 patients with a variety of cerebral lesions and in 10 normal controls. In 12 patients with focal brain lesions, no wave form could be recorded in one side. Of the remaining 23 sides, the average P₁ latency showed no difference from that of the normal controls. In 17 patients with diffuse brain lesions no wave form could be elicited in 12 sides. Average P₁ latency of remaining 22 sides showed statistically significant difference from that of normal controls. In this study it appears that delayed P₁ latencies are associated with diffuse cerebral lesions rather than with localized lesions.

The nitrite scavenging effect of three kinds of edible wild plants belong to Umbelliferaeceae family was investigated. The contents of crude protein, crude lipid and β-carotene of the plants were in the range of 22.99∼31.00%, 3.51∼5.08% and 5.40∼19.81 ㎎%, respectively. The content of ascorbic acid was very low and selenium was not detected in any samples. The contents of linoleic acid and linolenic acid were 66.46∼77.44%. The content of total phenol was 875.77 ㎎% in Ledebouriella seseloides WOLFF, which was the highest among the samples. The methanol fraction of the plant extract showed higher nitrite scavenging effect than the water fraction. The nitrite scavenging effects of the samples were the highest at pH 1.2 and lowest at pH 6.0, suggesting that it's pH dependent. Nitrite scavenging effect of methnol-soluble fractions obtained from Ledebouriella seseloides WOLFF was 95.3% at pH 1.2, which was the greatest among tested samples. There was a high correlation between the nitrite scavenging effect and the total phenol content.

Recently the development of CNC machine tools seems to bring about progressional high speed, precision, and automation in cutting processing, but is unlikely to avoid the generation of burr arising from plastic deformation, which may result in deterioration of improvement in the precision and productivity of products. This study conducted a comparative analysis of the sizes of burrs via two-dimensional low speed cutting experiments under varied different cutting conditions by taking as its materials of cutting A6061, A2014, STS304 and SM40C commonly used for precision machine paets, motor cars, aircrafts, and so on. When the depths of burrs increase, the size of the burrs are inclined to increase linearly at their final stage rather than the lateral sizes of the burrs. When cutting becomes fast in speed, the lateral sizes of burrs appear consistent, but from a relative perspective the sizes of the final burrs tend to be remarkably increased. An increase in the angle of inclination of α is seen as effective in reducing the thickness of burrs, and burrs were more decreased in size on coating tools rather than in uncoating tools.

The significance of the angle of anteversion of the femoral neck is widely recognised, especially in congenital dislocation of the hip, cerebral palsy, Legg-Calve´-Perthes' disease, and in-toeing gait. And many methods of measuring the anteversion have been described since the early work by Drehmann (1909) who determined anteversion by fluoroscopy. But there has been no reliable methods of measuring the angle until recently. The authors studies the comparative accuracy and reproducibility by the use of experimental model of femur on computerized tomography, axial technique (Dunn), biplanar method (RyderCrane) and fluoroscopic method (Rogers) and reported the results with consideration in clinical utility. 1. The most accurate and reproducible method is computerized tomography, but it has much clinical disadvantages such as uneconomy, limitid supply, more time requiring in measuring, and also limited information until the ossification of the femoral head was not occur (below the 18 months of age) 2. The next accurate and reproducible method is fluoroscopic method and this is widely useful except. the case of limited motion of hip joint. 3. The Ryder-Crane's biplanar method is very difficult measuring technique, limited in the situation of contracture, deformity around the hip. 4. The axial technique of Dunn are also useful in any state of hip joint and simple in its procedure. 5. The more applicable clinical selection of measuring the femoral anteversion are the combination of the above two or three methods and comparing it with the opposite hip.
