Since early times, paper has been the leading means of expression in human civilization. Along with the development of languages, people have used paper as their major intermediation measures to flourish the culture. At this point of time when studies in latest design are various and abundant, these fixed ideas on paper should be eliminated first for inventive thinking and freedom of expression. Because breaking the established notion helps to diversify the function of paper. We can see furniture made of paper come in useful to our ancestors in their daily life with the development of "Hanjiquot;. Each piece of paper furniture had its own function and beauty depending on processing method. Not only has been used for materials of basic modeling in the process of modern furniture designing, paper has also been used for the main material for the purpose of a new trial. If we try to find out the ways to take diverse characteristics of paper and develop them, while overcoming the defects of the material, paper has great potentiality for many kinds of use in furniture industry.

This paper describes a method for vision-based person identification that can detect, track, and recognize person from video using multiple cues: height and dressing colors. The method does not require constrained target's pose or fully frontal face image to identify the person. First, the system, which is connected to a pan-tilt-zoom camera, detects target using motion detection and human cardboard model. The system keeps tracking the moving target while it is trying to identify whether it is a human and identify who it is among the registered persons in the database. To segment the moving target from the background scene, we employ a version of background subtraction technique and some spatial filtering. Once the target is segmented, we then align the target with the generic human cardboard model to verify whether the detected target is a human. If the target is identified as a human, the card board model is also used to segment the body parts to obtain some salient features such as head, torso, and legs. The whole body silhouette is also analyzed to obtain the target's shape information such as height and slimness. We then use these multiple cues (at present, we uses shirt color, trousers color, and body height) to recognize the target using a supervised self-organization process. We preliminary tested the system on a set of 5 subjects with multiple clothes. The recognition rate is 100% if the person is wearing the clothes that were learned before. In case a person wears new dresses the system fail to identify. This means height is not enough to classify persons. We plan to extend the work by adding more cues such as skin color, and face recognition by utilizing the zoom capability of the camera to obtain high resolution view of face; then, evaluate the system with more subjects.

In this study of strategies used by young children in solving rectangular covering tasks before they have been taught area measurement, 75 5-, 6-, and 7-year-old children were asked to solve 3 rectangular covering tasks with a moveable unit. Three different sized units (4 cm., 2 cm., and 1 cm. cardboard squares) were provided and the children were asked to work out how many would be needed to cover a drawn rectangle. The resulting 5 developmental levels include incomplete covering, incomplete arrangement, complete covering, estimating, and measuring. Children using more advanced strategies were able to find correct number of units. While the tendency among older children was to use more advanced strategies, even 5-year-olds had an intuitive understanding of rectangular area measurement.

Since the 1960s when paper began to use as a structural material in furniture, design, the way of using paper was dramatically changed. Before the 1960s, paper was used mostly in decorative purposes like paper $mach\acute{e}$. The development of consumer culture in the 1960s created a new trend for paper in design. Paper became a material for dresses and chairs. Also, the types of paper that adapted on furniture varies from cardboard, paper tubes, glassine paper, honeycomb, etc. The variation of the material results to make possible to create a new form. Moreover, paperboard was broadly used in current society in such area that mostly structural based as architecture. Paper gives great opportunity not only to consumers to buy furniture in inexpensive price also to manufacturers to produce furniture and to test market easily, Moreover, paper furniture is mostly fun. Therefore, the creation of paper furniture becomes diverse in terms of design concept. This study explored the characteristics of paper furniture responding to social backgrounds by decade. Relation between types of paper and the characteristics is one of main points in this research. This study covers furniture design from the 1960s to present and mostly focuses on seating furniture where paper used as structural material. Researching on patent records and contemporary periodicals gave me helpful information on details of design process and consumer culture.

Elemental mercury exposure can result in significant toxicity. Source decontamination and remediation are often required after larger elemental mercury exposures, but the details of these processes are infrequently reported. In the case described herein, a 64-year-old woman and her husband were exposed to elemental mercury in their home after the husband purchased it online for the purpose of recreational barometer calibration. After the mercury reportedly spilled during the calibration process, a vacuum cleaner was used to decontaminate the affected surface; this led to extensive mercury contamination of the home. The couple was relocated from the home while remediation occurred over the course of several weeks. Vacuum cleaning of an elemental mercury spill can lead to extensive volatilization and recirculation of mercury vapor. For smaller mercury spills, careful removal of visible mercury beads by using an eyedropper, cardboard, and masking tape is recommended. Larger spills require professional decontamination and remediation and may necessitate involvement of governmental resources. Vacuum cleaning should not be used as an initial method of decontamination after elemental mercury exposure. Careful attention to source decontamination can reduce the emotional and financial costs associated with extensive remediation after elemental mercury exposure.

본 연구에서는 변화 탐지 수행에서 주의와 의식이 미치는 각각의 효과 크기에 대해 관찰하였다. 주의와 의식이 결합된 단서조건과 의식적 접근이 차단된 주의 단서가 제시된 조건에서 과제 수행결과를 비교하여 의식의 효과 크기를 확인하였으며, 의식적 접근이 차단된 주의 단서조건과 주의 단서가 없는 통제 조건에서 과제 수행결과를 비교하여 주의의 효과 크기를 확인하였다. 이를 위해 변화 탐지과제와 연속 플래시 억제(continuous flash suppression, CFS) 현상을 사용하였다. CFS는 한 쪽 눈에 빠르고 연속적으로 변화하는 몬드리안 패턴이 제시되었을 때 관찰자의 다른 쪽 눈에 제시된 정적 시각 자극을 인식하지 못하는 현상이다. CFS 현상을 촉발하기 위해 선행연구에서 주로 사용된 거울입체경 대신 스마트폰과 구글 카드보드를 사용하였다. 실험 1-1에서는 새로운 실험 기기로 구현한 CFS 현상이 시각자극의 인식을 억제하는데 선행연구와 유사한 결과를 보이는 것을 확인하였다. 실험 1-2에서는 강제선택과제를 수행할 때, 새로운 실험 기기를 통해 제시된 비의식적 자극이 단서로 충분히 작용하는지 알아보았다. 실험결과, 선행연구와 비교하여 비의식적 자극이 단서로서 주의를 끄는데 더욱 강하게 작용함을 알 수 있었다. 실험 1-1과 1-2를 통해서 스마트폰과 구글 카드보드를 사용하여 촉발한 CFS 현상을 후속연구에 사용하는데 적합하다고 판단하였다. 실험 2에서는 변화 탐지과제를 수행할 때, 제시되는 단서의 의식 수준을 조작하여 과제 수행에 의식과 주의가 미치는 효과크기를 알아보았다. 독립변인을 제외한 나머지를 유지하는 방법으로 해당 요인이 전체 수행에 미치는 효과를 분리하였다. 실험결과, 단서자극을 의식하는 수준에 따라 변화 탐지수행의 평균 정확도에서 유의미한 차이가 나타났다. 비의식적 단서는 의식적 단서가 제시되는 조건이나 단서가 제시되지 않는 조건과 다른 변화 탐지 패턴을 보임으로써 변화 탐지와 같은 인지적 처리과정에서 주의와 의식이 미치는 효과가 다름을 확인하였다. 이를 바탕으로 정보처리과정에서 의식과 주의가 과제수행에 미치는 효과의 크기를 관찰할 수 있었다.

The purposes of this study were to quantify and compare the kind and amount of solid waste generated in two school foodservice operations located in urban and rural areas. A waste stream analysis was conducted to quantify and characterize the kind of waste in the production and service parts of each operation. The SPSS 10.0 for window was used for data analysis. Non-parametric test (Mann-Whitney) was adopted to determine if significant differences exist in amounts of waste generated in the urban school and the rural school. An average of 415 meals, including 43 adult meals, were served daily in the urban school, while an average of 177 meals, including 24 adult meals, were served daily in the rural school. Food waste generated in the production part in the urban school composed approximately 87% and 45%, while that in the rural school composed 71% and 28% by weight and volume, respectively. Waste per meal was not significantly different between the urban school and the rural school in the production part except the cardboard waste. The total waste per meal at lunch was 154g or 465m1 in the urban school and 51g or 334m1 in the rural school. Students in the urban school discarded significantly more food waste and milk than students in the rural school did. The research results suggest that school foodservice dietitians should evaluate the acceptability of menu items based on food waste per meal, and assess the feasibility of implementing a plan for recycling packaging waste and composting organic waste.
