This study was initiated in order to find alternative fuel substituting for light oil the most common fuel for heating greenhouse. The tire oil used in this research was produced by pyrolysis process, one of the final products besides steel string and carbon black in which waste tires as a form of chopped pieces broken by shredding machine are heated up to 200~30$0^{\circ}C$ with maximum restraining of oxygen supply. In order to justify light oil equivalent qualities in tire oil combustion characteristics were defined in the way of comparing kinetic viscosities in the wide range of temperature flame sizes and exhaust gas components in the various combustion conditions. We found that kinetic viscosity of tire oil was lower than light oil by 1 to 2 cSt in the temperature range showing better flowing mobility in the fuel line of the burner and no significant difference in flame size between the two oils in the all combustion treatments. However much more NO and SO$_2$ were detected from the exhaust gases of tire oil than light oil combustions. In fact tire oil contains more nitrogen and total sulfur, by 25 times and 40 times respectively than light oil according to the composition analysis. Tolerable limit for SO$_2$discharge amount defined by the national air pollution standards is under 540ppm so tire oil combustion satisfies the requirement though. It is desirable if sulfur and nitrogen filtering process shall be added in the tire oil production line. Except the exhaust gas components all greenhouse heating qualities of tire oil including hot air temperature are very identical to those of light oil.

소프트웨어 개발 시 프로젝트 크기를 늘리는 것(scaling up)은 간단한 프로젝트를 가져다가 각 부분을 좀 더 크게 만드는 단순한 문제가 아니다. 프로젝트의 크기가 증가 할 때 의사소통도 유지되어야 하고, 비용, 생산성, 품질, 개발활동, 개발방법론 등도 고려되어야 한다. 본 논문에서는 소프트웨어 프로젝트의 크기로 인해 개발 될 소프트웨어 프로젝트가 실패하지 않도록 하기 위한 중요 요소들의 효율적인 사용방법들에 대해서 논의한다.

Facility Management (FM) is a project phase to maintenance and to increase the qualities of product which is planned on the design phase and ensured on the construction phase. In addition, since the approximate time occupied in operation and maintenance phase is the longest from construction project as total approximate cost is about 85% of whole the project, it could be managed and realized primarily. The information of facility is not created on the specific point of project, but it might be created on the whole process of subject project widely. Thus, as the information could not be lost and it can be delivered into computer aided facility management system, it is necessary to manage the facility information. This paper proposed the necessities and the problems of BIM-based data interoperability on the Korean construction projects.

The purposes of this study were to investigate the qualities of infant day-care centers and the caregivers' interactions with infants. Forty-six day-care centers from Seoul, Daejeon, and Daegu were enrolled in this study. Two kinds of methods were used for data collection; one was the Assessment Scale for Infant/Toddler Care Center developed by Choi and the other was the Qualitative Rating Scale for Caregiver used in the NICHD Early Child Care Project. Frequency, percentile, Crollbach's, one-way ANOVA, and Pearson's correlation were calculated for data analysis. Qualities on 5 factors of infant day-care centers were ranged from 3.44∼4.35, the highest with health managing and the lowest with support system in the Likert 5-point scales. Sensitivity, developmental stimulation and positive regard to child, which are the caregiver's positive interactions with infants were rated minimally or usually characteristic. In addition, intrusiveness, detachment, negative regard to child and flatness, which are negative interactions with infants were rated never or minimally characteristic. Finally, some suggestions for good quality and facilitation of infant care were made.

거듭 발전해온 여러 분야의 기술들은 공간과 물건들 그리고 우리들의 상호관계에 더욱 더 많은 영향을 주고 있다. 그러나, 그럼에도 불구하고 그 기술들로 이루어진 제품과 서비스를 이용하는 방법에는 한계성을 가지고 있다. 즉 아날로그의 우리의 생활환경과 디지털 정보환경의 존재 적 상이성으로 제품과 그 서비스의 사용성의 소통은 원활하지 못하고 있다. 예를 들어 ON과 OFF는 마치 BLACK과 WHITE처럼 표현되어 우리가 일상적으로 생활하는 아날로그 환경과는 달라 불편함을 느낄 때도 있다. 이 시점에서 디지털 정보환경의 사용성을 아날로그 적인 요소 (HUMAN QUALITY)를 가진 입력장치(INPUT DEVICE)의 개발과 제안은 의미가 있다. 이 연구의 궁극적인 목적은 제품과 그 제품이 가지는 서비스의 가치를 사용성을 중심으로 개선하고 제안하고자 함이다. 예를 들어 제품의 가치를 소통할 수 있는 방법은 그 기능에 접근성을 가진 SWITCH라고 할 수 있는데, 그 디지털 적 행위의 소통성으로 가진 스위치들은 제품의 기능과 서비스를 이해하기에 상당한 한계성을 가진다. 그래서 본 연구는 제품의 특성과 환경에 맞는 아날로그 입력장치를 개발하고 제안하고자한다. 시간, 패턴, 자유, 리듬 등을 ON과 OFF사이에 설정함으로서 존재하지만 볼 수 없었던 제품과 그 서비스의 가치를 찾아 좀더 자연스럽고 따뜻한 HUMAN QUALITY를 가진 제품을 만들고자 함이다. 단순히 ON, OFF가 아닌........

Futurism can be defined as a movement in the early 20th century founded by Italian writer Marinetti apposing to traditional and conservative art. Though its life as a movement seemed to be fairly short, it can be said that the very essence of futurism can be seen whenever there is radical change in our society such as the information revolution. Even though the information revolution has brought us many positive improvements our life including art and design, lately there are also discussions about the defects in our life. Ron Arad may be considered as a designer and artist whose intentions and expressions are very similar to those of futurism. This study investigates concepts, meanings, and expressions of futurism in art history and then those of Ron Arad's shown in interior design projects. By examining selected project examples the author defined that rather than optimistic viewpoints, avant-garde and technological aspects were found to be strong in symbolic qualities. As for expressive qualities, dynamism and continuity appeared to be Ron Arad's unique expressions, very similar to those of futurism on the other hand, purity and temporarily were found less. It is hoped that the study may be a help in better understanding futuristic qualities of Ron Arad, one of the radical and experimental designers of our age.

Stakeholder management in construction projects is an important factor in project performance creation. The purpose of this study is to verify the effect of the recognition of the importance of the quality influence factors among the stakeholders of the construction project on the perceived quality and the project performance. The impact of the project management methodology on the project performance has been actively researched, but there is little research result on the project stakeholders. The projects to be researched are apartments and buildings that have been completed within the last five years of domestic large construction company. The method of survey is to measure the consensus of the importance of the quality influential factors among the three parties such as the ordering party, the design supervisor and the constructor, and confirm whether the agreement affects the quality of the actual project. Finally, the research model was verified by surveying the satisfaction of the client on the final product. The results are as follow. The degree of agreement on the importance of quality influential factors among stakeholders has a significant effect on perceived quality. In the relationship between perceived quality of influence factors, organizational (support) quality influenced technological quality and managerial quality, and technological quality and managerial quality also have significant influence on resource quality. The results of analysis showed that perceived quality of resources strongly influenced project performance. The remaining three experienced qualities also significantly affect project performance.

This study based on the hypothesis which the spatial qualities in the Mies's early works are not extinct but potentially immanent in his latter works. In Mies's early works, destruction of outline, centrifugal extension of fluid space, and asymmetry are distinctly showed. These qualities probably revert to the indefiniteness of space. In Mies's latter works, however, these dynamic qualities are disappeared. Geometrically precise outline and exact grid structure represent universal space derived from zero-degree pure box. These qualities probably revert to tile definiteness of space, characterized by the unmovable emptiness. Although Mies works vary in external form, his expression technique of space reveals continually both the qualify of definitive and indefinitive space. For example, in the Museum for a Small City(1942) unbuilt project. elements defined by the perspective are fixed and static, but elements defined by the collages are floated and dynamic. The former reigns over the realized buildings of Mies, while the latter seems to be latent in terms of Schein which transcends reality. If we can penetrate this point, it's possible to read the other side of Mies' architectural works, distinct from both the canonized interpretation and the excessive criticism. Point is that later works of Mies must be understood as interplay of universal space appeared as phenomenon and flowing elements latent in. Architectural space of Mies keeps a distance with actual space through latent manner of being while preserves the empirical actuality It provides us with an occasion which appears only in an instant, in which even the ordinary things reveal its poetics.
