소프트콘택트렌즈의 착용시간의 증가에 따른 소프트콘택트렌즈의 순간적인 움직임 변화를 알아보기 위하여 8종의 소프트콘택트렌즈를 안질환을 가지고 있지 않는 10명에게 착용시키고 초고속촬영기(FASTCAM ultima 1024)를 이용하여 측정하였다. 착용 15분 후에 순목으로 인한 각막에서의 움직임을 비교하였을 때, 8종의 소프트콘택트렌즈 모두 수직방향이 수평방향보다 약 2배 정도 더 많이 움직였으나, 그 정도는 렌즈에 따라 상이하였다. 순목시 소프트콘택트렌즈가 순간적으로 움직인 거리는 렌즈의 종류에 따라 차이가 있어 일일 착용렌즈인 A 렌즈, B 렌즈의 경우 다른 렌즈에 비해 움직임이 상대적으로 많았으며 통계적으로도 유의성 있는 차이를 보였다. 이러한 순목에 의한 순간적인 움직임은 8시간 동안 착용한 후에는 모든 렌즈에서 크게 감소하였다. 렌즈에 따라 수평방향은 24.6~60.0% 수준까지, 수직방향은 20.4~94.3% 수준까지 감소하였다. 상대적으로 함수율이 높은 A, B, C 렌즈에서 움직임의 감소가 컸다. 따라서 소프트콘택트렌즈를 착용함에 의해 움직임의 감소가 나타나고 이로 인하여 누액순환이 영향을 받을 수 있으리라 사료된다.

이 연구에서는 1920~30년대 『동아일보』, 『조선일보』에 게재된 이동도서관 설립 운동 및 독서지도론을 중심으로, 아동 독서운동의 전개상을 고찰하였다. 즉 당대 두 신문에서는 아동독서의 중요성을 강조하면서, 아동도서관 설립의 필요성, 아동 독서지도 및 독서경향 관련된 기사들을 꾸준히 게재했다. 본고에서는 이를 주목하며 다음과 같은 내용을 분석하였다. 첫째, 1920~30년대 아동 독서를 강조한 배경적 의미와 이와 병행된 아동서관 설립에 대한 논의들을 탐색했다. 이를 통해 일제강점기 민족운동과 아동교육의 관계, 당대 독서가 지니는 의미 등을 검토했다. 둘째, 이와 함께 당시 활발하게 전개되었던 아동도서관 운동 전개 양상과 독서란을 통해 제시되었던 독서교육 방법론을 분석하였다. 이 시기는 그 어느 때보다 아동 독서교육에 대한 관심이 지대했다. 여기에 아동도서관 운동이 활발하게 전개되면서 각지에 소년문고가 다수 설치되기도 했다. 한편 신문의 독서란에는 학교와 가정에서의 독서지도법도 다수 게재되었으며, 선진적인 해외 독서교육 사례를 통해 그 모본을 제시하기도 했다. 이상의 분석 결과를 통해 1920~30년대는 아동 독서운동이 적극적으로 전개된 시기임을 알 수 있다.

시계열 데이터를 예측하는 것은 매우 어려운 작업이다. 비선형적인 특성을 갖는 신호에서 얻어지는 데이터들이 불확실성을 가지고 있기 때문이다. 본 논문은 특정 시계열 데이터의 정확한 예측을 위하여 시계열 자료가 어떤 패턴에 따라 변화한다는 전제하에서 과거 자료들을 평균하여 미분으로써, 시계열 변화 패턴의 찾았다. 또한 미분 데이터의 반영 비율에 따라 특이성을 갖는 시계열데이터를 일반화하기 위하여 확률변수를 적용하였다. 순환변동과 계절변동을 소거하고, 불규칙 변동만을 추출하여 경향의 추세를 더한 예측값을 계산하게 된다. 이렇게 예측된 값은 이동평균과 단순이동평균에 의하여 가장 좋은 결과값을 갖는 알고리즘과 비교를 통하여 제안 알고리즘의 우수성을 입증하였다.

In this research the energy degrader, which is the most fragile part of the security of a target, has been newly designed to improve the performance of the gas target. Also, the numerical analysis of the heat movement and mechanical movement during the operation of the target has been accomplished. The heat analysis and structure analysis which are using the cooling water flow and pressure in the energy degrader and the Nastran mediocrity finite element analysis program, has been considered with the heat movement and mechanical movement according to the current capacity of proton beam which determines the production yield of the radioactive isotope. Also the possible use range has been determined, and at the same time the most suitable running condition according to the current capacity of proton beam has been suggested.

In the rainfalll-runoff relation, consideration of the spatial movement of storms is very unportant in designing a hydraulic structure or evaluating an environmental influence for land usage. Because of thins reason, this study has suggested the finite element model which consider the spatial movement of a storm and it was applied on a small river basin(Wi stream basin). In the application of the model, the basin was treated as a pivot point and the storms are simulated 10 movement in each directions. As a result, It shows that the storms moving from north to south have higher peak discharge and faster peak time than the storms moving in other directions. So these characteristics have to be considered In the designation of a hydraulic structure or evaluation of an environmental influence.

When people recognize a landscape, they first need to see it for a definite period time. This study clarified the way green space in a landscape is recognized using eye movement analysis, and evaluated the Pffi9bility for quantifying stress-reducing effects of seeing a landscape. The results of the experiments on eye movement analysis suggest that the way of recognizing green space in a landscape may depend on a ratio of the amount of scenic greenery in a landscape, color and greenery layout. Especially, this study also suggests that the possibility of the greenery layout guiding eye movement could be verified by conducting a study on planting patterns. In addition, the results of the experiments for quantifying stress-reducing substances found that it is likely that a green space in an urban area has stress-reducing effects.

In this experiment, we proposed and implemented a disease forecasting system using a received signal strength indication ZigBee-based wireless network with a 3-axis acceleration sensor to detect illness at an early stage by monitoring movement of experimentally infected weaned piglets. Twenty seven piglets were divided into control, Salmonella enteritidis (SE) infection, and Escherichia coli (EC) infection group, and their movements were monitored for five days using wireless sensor nodes on their backs. Data generated showed the 3-axis movement of piglets (X-axis: left and right direction, Y-axis: anteroposterior direction, and Z-axis: up and down direction) at five different time periods. Piglets in both infected groups had lower weight gain and feed intake, as well as higher feed conversion ratios than the control group (p<0.05). Infection with SE and EC resulted in reduced body temperature of the piglets at day 2, 4, and 5 (p<0.05). The early morning X-axis movement did not differ between groups; however, the Y-axis movement was higher in the EC group (day 1 and 2), and the Z-axis movement was higher in the EC (day 1) and SE group (day 4) during different experimental periods (p<0.05). The morning X and Y-axis movement did not differ between treatment groups. However, the Z-axis movement was higher in both infected groups at day 1 and lower at day 4 compared to the control (p<0.05). The midday X-axis movement was significantly lower in both infected groups (day 4 and 5) compared to the control (p<0.05), whereas the Y-axis movement did not differ. The Z-axis movement was highest in the SE group at day 1 and 2 and lower at day 4 and 5 (p<0.05). Evening X-axis movement was highest in the control group throughout the experimental period. During day 1 and 2, the Z-axis movement was higher in both of the infected groups; whereas it was lower in the SE group during day 3 and 4 (p<0.05). During day 1 and 2, the night X-axis movement was lower and the Z-axis movement was higher in the infected piglets (p<0.05). Overall, the movement of infected piglets was altered, and the acceleration sensor could be successfully employed for monitoring pig activity.

The purpose of this study is to research characteristics of costume which is expressed in Gustav Klimt's Paintings. In the end of 19th century and the beginning of 20century Vienna, considered to be the fashion Mecca after Paris, the creativity of such artists allowed the 'Anti-Fashion Movement' to set itself up against the frippery of the costume of the time. The Secession Movement received the effect of Art Nouveau and Symbolism and Klimt led of this movement as a forerunner in Vienna. Many women appealed in Klimt's Painting with unique costume which contrast to traditional fashion that period time. The characteristics of costume in his paintings are as follows. Firstly, Klimt drew in the women's costume which made by designers of Vienna Workshops, at one of motive of his work of art. Costume got a opportunity became a new art field, because there was no conceptual thinking of a fashion designer at that time. Secondly, the costume of Klimt' paintings had both anti-fashion design and elements of fashion, so he gained considerable support from leaders of high fashion who was the upper classes. Thirdly, both anti-fashion and fashion appeared in his painting at first period. Costume which made at the Vienne Workshop appealed portraits of Klimt paints at the second period. Klimt interested in Naturalism, Japonism, Orientalism and Greece style and expressed his characteristic techniques at the last period. Lastly, Klimt liberated the woman from a physical and spirit restriction through his various artistic presentations.
