20세기 이후 산업화한 소비사회에서 생산된 기성품들은 '파운드 오브제 (Found object)'라는 새로운 소재로 미술작가들에게 채택되어 작품 속에서 넓은 의미로 재해석 되고 있다. 이를 활용해서 새로운 의미를 부여하는 방법은 표현양식뿐만 아니라 개념적으로도 확장된 새로운 패러다임을 생성한다. 현대미술에서 최초로 파운드 오브제가 사용된 1912년 파블로 피카소(Pablo Picasso)의 이후 다다이즘과 초현실주의, 그리고 팝아트를 통해서 파운드 오브제의 전개를 파악하고 20세기 후반 파운드 오브제의 표현에 대해서 알아본다. 본 연구에서는 파운드 오브제가 작품에서 혼합된 방식에 따라서 '가공되지 않은 오브제', '변용된 오브제', 그리고 '차용된 오브제', 등 3가지 유형으로 구분하여 작가와 작품을 분석한다. 본 연구를 통해서 파운드 오브제를 융복합한 작품은 대상을 물질적으로 발전시킬 뿐만 아니라 미술의 전통적 규범에서 벗어나 자유로운 개념의 미술을 실천할 수 있도록 한다는 점에 주목한다.

The aim of this study is to investigate the relationship between the object ability, basic movement ability, and mathematical ability of young children. Next, through this study, the influence of young children's object manipulation ability and basic movement ability on mathematical ability was investigated. The subjects of this study were 80 children aged 5 years old. As a research tool, the non-mobile movement and mobile movement, the basic movement development test scale, and the young children's picture-mathematical ability test scale were used. This survey was conducted from October 2018 to January 2019. For data analysis, correlation analysis and hierarchical multiple regression analysis were performed using the spss program. As a result of the study, it was found that there was a significant positive correlation between the non-mobile ability, movement ability, object manipulation ability and mathematical ability of young children. It was found that young children's ability to manipulate objects and non-movement abilities had positive effect on their mathematical abilities. The movement ability of young children had both negative and positive effects on mathematical ability, but it was not found to be statistically significant. This study is meaningful in that it investigated the effects of non-mobile movement, mobile movement ability, and object manipulation ability, which are sub-capabilities of basic movement ability, which had not been investigated so far, on the mathematical ability of young children.

This paper introduces the industrial problem, the solution, and the results of the research conducted with Define Inc. The client company wanted to improve the performance of an object detection model on the floor plan dataset. To solve the problem, we analyzed the operational principles, advantages, and disadvantages of the existing object detection model, identified the characteristics of the floor plan dataset, and proposed to use of YOLO v5 as an appropriate object detection model for training the dataset. We compared the performance of the existing model and the proposed model using mAP@60, and verified the object detection results with real test data, and found that the performance increase of mAP@60 was 0.08 higher with a 25% shorter inference time. We also found that the training time of the proposed YOLO v5 was 71% shorter than the existing model because it has a simpler structure. In this paper, we have shown that the object detection model for the floor plan dataset can achieve better performance while reducing the training time. We expect that it will be useful for solving other industrial problems related to object detection in the future. We also believe that this result can be extended to study object recognition in 3D floor plan dataset.

Optical observation is one of the most common techniques used for characterizing the physical properties of unknown objects and debris in space. This research presents measurements and properties of the new object 96019 from ground-based optical methods. Optical observations of this small object were performed using a charge-coupled device (CCD) camera and the Santel-500 telescope at the Zvenigorod Observatory. The orbital elements and physical properties of this object, such as area-to-mass ratio, have been determined. The results show that this small object has a low area-to-mass ratio, between 0.009 and $0.12m^2/kg$. The light curve of object 96019 is given: Over the time intervals, variations in brightness are analyzed and the maximum brightness was found to be 12.4 magnitudes. The observational results show that, this object brightens by about three magnitudes over a time span of three minutes. Based on these observations, the characteristics and physical properties of this object are discussed.

본 연구의 목적은 도구를 사용하더라도 닿지 않는 거리에 놓인 대상에서 도구 길이에 따라 지각된 거리가 상이한 정도로 압축되는지, 그리고 가리키는 대상에서만 도구 길이에 따라 지각된 거리가 압축되는지를 검증하는 것이다. 자기중심적 거리를 측정한 실험 1은 도구를 사용하여 닿지 않는 거리에 놓인 대상에서도 도구 길이가 길어질수록 대상까지의 거리를 더 가깝게 지각한다는 것을 발견하였다. 자기중심적 거리를 측정한 실험 2는 가리키는 대상과 가리키지 않는 대상이 시야에 공존할 때 도구 길이가 가리키지 않는 대상까지의 거리 지각에 영향을 미치지 않는다는 것을 발견하였다. 실험 3은 실험 2와 동일한 환경에서 표적과 측정 대상 사이의 거리인 대상중심적 거리를 측정하여 도구 길이가 표적의 거리지각에만 영향을 미친다는 것을 발견하였다. 이와 같은 실험 결과는 도구를 사용하여 닿을 수 없는 거리에서도 지각된 거리의 압축 현상이 나타나며 이와 같은 지각된 거리의 압축 현상은 가리키는 대상에 국한된다는 것을 시사한다.

In this paper, a new target extraction algorithm is proposed, in which the coordinates of target are obtained adaptively by using the difference image information and the optical BPEJTC(binary phase extraction joint transform correlator) with which the target object can be segmented from the input image and background noises are removed in the stereo vision system. First, the proposed algorithm extracts the target object by removing the background noises through the difference image information of the sequential left images and then controlls the pan/tilt and convergence angle of the stereo camera by using the coordinates of the target position obtained from the optical BPEJTC between the extracted target image and the input image. From some experimental results, it is found that the proposed algorithm can extract the target object from the input image with background noises and then, effectively track the target object in real time. Finally, a possibility of implementation of the adaptive stereo object tracking system by using the proposed algorithm is also suggested.

This study proposes the concept and measurement of object-oriented systems modelling activity based on the previous research in the area of systems engineering, object-oriented modelling, and information systems. The modelling activity is related to information systems development success for exploring the correlation of each other. The object-oriented modeling activity is found to be related to user satisfaction with developed information systems, But the modeling activity does not have relation to the other successes, such as cost, development schedule, and maintenance. This study contributes to systems development modeling research, systems success, and object-oriented systems modelling research. Practically, the results support the usefulness of object-oriented modelling effort in the field in terms of user satisfaction.

본 연구는 두 가지 이론적 모델인 통합된 객체 모형과 특장 병렬-독립 저장 모형을 검증함으로써 시각작업기억 표상의 특성을 조사하였다. 실험 I에서 참가자들은 색상 사각형, 방위 막대 또는 두 가지 모두로 구성된 배열을 기억한 뒤 이를 토대로 변화탐지과제를 수행했다. 단일 특징 조건에서 기억배열은 하나의 특징(방위 또는 색상)으로만 구성된 반면, 두 가지 특징 조건은 둘 모두를 포함했다. 두 조건간 변화탐지 수행의 차이는 없었으며 이는 병렬-독립 저장 모형보다는 통합된 객체 모형을 지지한다. 실험 II에서는 이등변삼각형의 방위, 색상 사각형 또는 두 특징 모두로 구성된 기억배열을 대상으로 회상과제가 실시되었으며, 단일 특징과 두 가지 특징 조건 간 회상 수행이 비교되었다. 두 조건 간 회상 정확도에는 차이가 없었으나 표상 선명도와 추측반응에 대한 분석 결과는 강한 객체 모형보다는 약한 객체 모형을 시사했다. 본 연구의 결과는 시각작업기억의 표상 특성을 둘러싼 현시점의 논쟁에 있어서 병렬-독립 저장 모형이 아닌 통합된 객체 모형의 우세를 지지한다.

Though the studies on object-oriented software design which software component corresponds to phrases appearing in sentences of natural language have been going on, the design methodology has not been clearly set up yet. In this paper, the module structure of good quality was found not only by nouns that indicate class of object but also by subdividing sentences. I also suggested objected-oriented methodology observing the interdependency between objects and their relationships, and assessed the control problem of lift as an example.

In this paper, we propose a method to search the evidence such as a knife found in the crime scene based on GHT from an image database Such objects like knives are simitar in shape. The proposed method utilizes the small shape differences among objects as much as possible to distinguish an object from similar shaped objects. It consists of the GHT based candidate generation and top-down candidate verification. For the fast generation of the candidate 1ist, the GHT operation is performed un the down sampled edge list. The test results show that it can retrieve the correct object even with a pan of object in reasonable time.
