Continuous loading is applied the sample has been developed to overcome some of the problems associated with the incremental loading consolidation test. Therefore, it is able to reduce the test time and provide a well defined the curve of effective stress versus strain due to continuous stress-strain points. Also, the constant rate of strain consolidation(CRSC) test has been accepted widely as a standard method in foreign countries because of its many advantages. However, in Korea the CRSC test has not been used in engineering practice and experimentally verified. Because there is not a precise criterion of testing despite consolidation characteristics are influenced on strain rate and Pore pressure ratio. Consequently, it is difficult to apply in engineering practice. In this study, artificial neural networks are applied to the estimation of th proper strain rate and pore pressure ratio of the CRSC test. This study shows the possibility of utilizing the artificial neural networks model of estimation of the strain rate and pore pressure ratio in the CRSC test.

This study analyzed the influencing factors of learning engagement and teaching presence in online programming practice classes. The subjects of this study were students enrolled in an industrial specialized high school, who practiced creating Arduino circuits and programming using a web-based virtual practice tool called Tinkercad. This research adopted a tool that can measure task value, learning flow, learning engagement, and teaching presence. Based on this analysis, learning flow had a mediating effect between task value and online learning engagement, as well as between task value and teaching presence. Increasing learning engagement in online classes requires sensitizing the learners about task value, using hands-on platforms available online, and expanding interaction with instructors to increase learning flow of students. Furthermore, using virtual hands-on tools in online programming classes is relevant in increasing learning engagement. Future research tasks include: confirming the effectiveness of online learning engagement and teaching presence through pre- and post-tests, and conducting research on various practical subjects.

This paper has investigated the cultural practices influencing business performance and integrity in selected Malaysian contractors and has discussed culture related issues to improve the management of cultural capitals in the Malaysian construction industry. Issues of current enterprise culture and applicable cultural practices, leadership styles, enterprise axiology and integrity, cultural practices and loyalty, and identification of organizational culture are discussed during the semi-structured interviews and questionnaire survey. Conclusions has been drawn that the people oriented and task oriented management style have a similar quantity of supporters in Malaysian contractors. The integrity and profit are respectively identified as the enterprise axiology in the ethical and economic perspective. The monkey culture is considered as the most applicable type for the cultural practice and the current enterprise cultures applied in the Malaysian contractors are mostly positive to both the organizations and society.

In Japan, it has been argued between architects and contractors that which process is desirable, the traditional process or the design-build process. It is called the contractor-designer issue. In 1968, Kajima Corporation chairman Morinosuke Kajima and the Japan Architects Association had a public controversy over it. On the other hand, in practice, architects and contractors have secured quality of buildings thorough a close communication in the design and construction process of building. What are the relationships between architects and contractors? What roles do architects and contractors have in practice? This study has two aims. First one is to analyze the contractor-designer issue based on roles and relationships between architects and contractors, and then to show conflicts between them. Second one is to consider issues which architects face in the relationships with contractors.

Small islands in humid and hot climates have received less attention development due to lack of resources and difficulties for in-situ construction. This paper addresses this problem by presenting a modular system for sustainable construction of a resort hotel in accordance with the international tourism standards, in addition to, minimizing undesirable effects on nature. This has been achieved by review of literature in the scope of off-site construction and identification of the natural geographical features of Herndurabi Island. According to the information acquired, a feasibility study and design practice have been conducted to achieve a reasonable solution to equip Hendurabi Island as a sample with a self-sufficient prefabricate resort hotel. Findings indicate that the volumetric prefabricated modules would be a solution to devising a framework for design and construction in remote regions.

This study is on the practice and limitation of the environment improvement project in the delinquent residential areas implemented as part of the urban restoration project that this study was carried out with the subject of the Saeddeul Village Project in Balhan Dongmunsan District of Donghae City that is implemented as part of resident-participating urban rehabilitation that has emerged as a socially important issue. In particular, at a time the issues of increasing senior population and poverty resulted thereof have surfaced in the society that this study has taken a look at the characteristics in the planning and practice process in the Saeddeul Village Project area for the purpose of improving the mental health. In the planning process and practice process, those human-care project and resident competency strengthening projects, together with physical environment improvement, are implemented, and the contents implemented by respective project are purported to establish the community identity through voluntary participation of local residents together with the environment improvement of the villages on the basis of resident participation as well as leading the economic independence by the village with its own discretion. However, the limitations in the practice process and exposure of problems that may be experienced in the field have made difficulties in such approach and provokes the difficulties of project performance depending on the conflicts in community constituents. Under such a relationship, it is required to have the endeavors to facilitate the community and solution of issued, and this study presents the need of access for revitalizing the regional welfare system.

최근 SW 실습 교육을 위해 수강생 별로 PC를 구비하는 대신 클라우드 상의 가상 PC를 할당해서 운영하는 사례가 늘고 있다. 본 논문에서는 클라우드를 이용해서 각 수강생의 SW 실습 환경을 효율적으로 구축할 수 있는 리눅스 기반 플랫폼을 설계하고 구현하였다. 본 논문의 플랫폼에서는 강사가 모든 수강생의 가상머신 템플릿을 일괄적으로 생성 및 통제할 수 있으며, 수강생들은 한 학기 동안 관리자 권한으로 본인의 머신을 관리하고 실습을 수행할 수 있다. 이때, 개별 머신에 발생하는 문제를 강사가 해결하거나 복원하는 효율적인 기능 또한 제공된다. 한편, 이러한 방식을 클라우드에서 실현하기 위한 가장 큰 어려움은 소요 비용을 미리 예측하기 어렵다는 데에 있다. 본 논문에서는 클라우드 이용 요금을 실시간으로 예측할 수 있는 모델을 설계하고, 사용자별 가상머신에 데몬을 두어 자원의 사용량 및 요금을 실시간으로 예측한다. 본 논문의 방식이 오버헤드가 거의 없음에도 실제 클라우드 사업자가 측정한 자원 사용량을 정확하게 예측하는 것을 확인할 수 있었다. 제안한 모델의 검증을 위해 리눅스 실습 강좌에서 한 학기 동안 클라우드를 활용한 결과 실제 청구 요금과 제안한 모델의 결과가 매우 유사한 것으로 확인되었다.

본 연구는 과학공학 융합 수업을 통해 학생들의 공학과 공학자에 대한 인식이 어떻게 변화되었는지 알아보기 위한 연구이다. 본 연구에서 사용한 과학공학 융합 수업은 제한된 예산과 시간동안 공학적 문제를 해결하는 24차시 수업으로 설계되었으며 20명의 초등 과학 영재 학생들에게 적용하였다. 본 연구의 주요데이터는 공학자 그림 그리기와 설명문항, 그리고 이에 대한 개별 인터뷰와 초점 집단 면접을 통해 수집되었으며, 공학자 그리기에 대한 설명과 인터뷰는 전사내용을 토대로 양적(빈도분석과 대응표본 t-검증), 질적 분석 방법을 모두 사용하여 분석하였다. 과학공학 융합 수업은 과학 영재 학생들의 공학 설계에 대한 이해에 긍정적인 영향을 미치는 것으로 나타났다. 또한 공학과 공학자, 그리고 공학과 사회의 관계에 대한 인식도 바람직한 방향으로 변화하였다. 공학은 여러 명이 협력하는 사회적인 활동이라는 인식, 그리고 공학자의 윤리의식, 공학의 사회적 가치 등 공학과 사회의 관계에 대한 인식도 바람직하게 변화하였다.
