The authors examined a college mathematics professor's change process in teaching practice by analyzing the teacher's reflective journal. Her change engaged cooperative learning method in a college Algebra course and was geared toward the reform-oriented methods. The change processes were revealed as a bumpy road that was full of struggles and challenges to both the teacher and students. The analysis also showed that a reflective journey needed a proper means and support system from a teacher's environment such as institution. This research clearly showed that brining a genuine change in teaching practice toward a broad educational goal was a combined effort among the participants of education.

This study researched that the remodeling was executed desirably in the side of deweller's household to the subject of ten apartment housings located in Gwang-ju, Jun-nam province. The study method was used the field study method and used in parallel with participant observation. As a result of the study, first, the problems of remodeling enforcement process are brought about standardized design, bad construction and the difficulty of solution in the defect occurrence. Second, By that request of the household is not reflected, the room except bedroom and the bathroom of inner room are low practical use degree. And wash space, garden space, assistant space of kitchen work were becoming hindrance factor of the residing environment because the use is irrational.

Fiber reinforced concrete (FRC) has been successfully used to enhance the flexural toughness of concrete. As fibers are randomly oriented in FRC, they sometimes produce clumps that reduce the mechanical performance, and a properly chosen mixing protocol can be a way to minimize this problem. In this research, the effects of mixing method on the mechanical properties of FRC were investigated. The compressive strength, flexural strength, and flexural toughness were measured using three different mixing methods. It was shown from the results that the compressive strength and peak flexural load were not affected by changes in mixing method. However, in terms of flexural toughness, the changes in mixing method clearly affected the flexural toughness of FRC. The truck-mixed FRC outperformed two pan-mixed FRCs.

With developments of architectural and information technologies at the knowledge-information oriented society in the 21st century, there are the needs on intelligent buildings equipped with advanced systems to integrate both technologies. The intelligent building means a smart building which provides comfortable environments, realizes fast and speed information and telecommunication network services, and maximizes work productivities by adopting various systems suitable to uses, sizes, and functions of buildings. In order to meet these needs of the times, the domestic intelligent building certification system has been enforced in 2006. Recently, the intelligent building certification system was newly revised for revitalizing the spread of intelligent buildings. Thus, this paper investigates rating criteria and assessment standards of the new certification system focused on office building projects and suggests strategies for obtaining certifications by analyzing cases which were certified on the previous version of the system.

With the development of industrial technology an amount of information has sharply increased and an information-oriented society had come. This information environment changed the function of library. Today's public library not only save and record the information but also encourages residents to use information and culture activities such as lifelong education. As the library plays a variety role, it has become an multiplex space. Added new function, various space has formed and each space requires their own interior images that fits it's character. Here this study is to research new changed library's characteristic in interior image through five library's on-the-spot survey.

오늘날 분산 컴퓨팅 환경은 사용자들에게 물리적인 위치와 상관없이 신속한 서비스를 제공하는 위치의 투명성이 부각되고 있다. 이를 위해 분산환경에서 객체를 설계하고 구현하는데 따른 표준화 방법으로 OMG에서는 OMA를 도입하여 OMA의 추상객체모델 위에 CORBA를 표준으로 정의하였다. 이러한 분산환경을 기반으로 복잡한 분산 어플리케이션의 개발과 관리의 복잡성을 줄이기 위해서는 객체들을 집합체적인 개념으로 그룹객체에 대한 정의를 필요로 한다. 따라서, 본 논문에서는 그룹객체 정의를 도입하여 현재 분산 시스템의 표준으로 사용하는 CORBA 기반에서 분산된 객체들을 효율적으로 관리할 수 있는 그룹객체 모델 즉, 구조를 제안한다.

The dynamic nature of the World Wide Web challenges Information Retrieval System to find information relevant and recent. Intelligent agents can complement the power of search engines to deal with this challenge. In this paper, we explain in manner of building Information Retrieval System based on intelligent agent technology. We present a tool called Websearcher. It was performed in Java environment. The object-oriented nature of Java and built-in facilities for multi-thread decreased our implementation effort. A modular software design makes it easy to configure the system for various experiments.

This study analyzes how well-being lifestyle and functional textile knowledge effect the perception of high functional sports/leisure wear importance. A survey was conducted among male and female sports/leisure wear consumers aged 15 and over in the Daegu and Gyeongbuk area from May $12^{th}$ to June $2^{nd}$ 2009. A total of 288 responses were analyzed using descriptive statistics, factor analysis, and regression. As a result, 9 factors were determined as sub-elements of a well-being lifestyle. Knowledge levels for functional textiles were high in elastic, UV blocking, air permeable, and antibacterial properties. The perception of high functional sports/leisure wear importance was positively influenced by functional textile knowledge and two well-being lifestyle constructing factors ('self-confidence/affirmative thinking' and 'health/environment oriented eating habits').

There are many researches on visual languages, but the most of them are difficult to support various collaborative interactions on a distributed multimedia environment. So, this paper suggests a collaborative visual language for interaction between multi-users. The visual language can describe a conceptual model for collaborative interactions between multi-users. Using the visual language, generated visual sentences consist of object icons and interaction operators. An object icon represents a user who is responsible for a collaborative activity, has dynamic attributes of a user, and supports flexible interaction between multi-users. An interaction operator represents an interactive relation between multi-users and supports various collaborative interactions. Merits of the visual language are as follows: supporting of both asynchronous interaction and synchronous interaction, supporting flexible interaction between multi-users according to participation or leave of users, supporting a user oriented modeling, etc. For example, an application to a workflow system for document approval is illustrated. So we could be found that the visual language shows a collaborative interaction.

Recently, the role of container ports is radically changing. These changes are largely driven by the innovation process of Logistics such as Supply Chain Logistics and Global Logistics due to the international expansion of industry. Under this environment, It is required that the container port should act as a integral part of a Supply Logistics Chain especially to provide the customer-oriented logistics service. This paper deals with the development strategy of container ports coping with these changes in the view point of container ports as a Logistics infrastructure to provide customer-response services and necessary to the economic promotion of hinterlands. Strategy is suggested in the phases of the customers desire, the pattern of container cargo, the economic promotion of hinterlands, and interrelation of container ports in north-east Asia and also domestics through the analysis of competiveness of container ports.
