It is important that students are provided opportunities to practice their skills in acquiring radiographic images. However, these opportunities are currently limited because of the risk of radiation exposure. To overcome this limitation, a new augmented reality-based radiography simulator was developed that enables students to practice radiographic techniques as part of self-directed learning without time and space constraints. Subsequently, cross-sectional images of a manikin phantom head obtained via computed tomography were reconstructed into a three-dimensional object. An image marker that could be recognized by a mobile device and could allow users to practice dental radiography techniques was devised. The three-dimensional object was augmented to the mobile device; consequently, among 106 stored dental radiographs on the device, a radiograph corresponding to specific imaging conditions was opened when users performed radiographic procedures. This technology could improve dental students' understanding of dental anatomy and contribute to improving their competency in acquiring dental radiographs.

Owning to rapid infrastructure development, Asia is experiencing dramatic economic growth. There are not a few cases in which, however, economic growth is achieved by increasing the external diseconomy. Pursuit of sustainable development is one of the most important issues for mankind. Under the post-industrial capitalism society, however, there seems a big risk of increase in the external diseconomy worldwide. The objectives of this manuscript are to discuss importance of risk management of construction practice in present and future. Regarding the latter, a particular attempt is made to discuss how project risk communication should be done to reduce the external diseconomy. Presently, one of the important issues in implementation of infrastructure projects is practice of risk management to properly manage time, cost, quality, and safety: mainly maximization of internal economy. Multi-party risk and uncertainty management process (MRUMP) is one of tolls to assist it. The idea on MRUMP can be used to reduce the external diseconomy through identifying, sharing, and tuning people's rhythms.

최근 해외시장에서는 Single Point Responsibility 개념의 선호와 프로세스사업관리능력의 중요성으로 건설사업관리 (Construction Management: 이하 CM)방식이 프로젝트 조달의 중요한 방안으로 사용되며 국내에서도 최근 CM 발주량의 획기적인 증가추세로 사업수행능력 향상을 위한 도구 개발이 절실하다. 가장 유용한 도구로는 국내${\cdot}$외 CM 수행사례 분석을 통해 이에 저해되는 요인과 모범사례 등을 파악하여 산업계로 하여금 체계적 점검과 벤치마킹을 통해 수행능력을 제고할 수 있는 핵심성공요인과 Best Practice의 보급 발간이다. 따라서 본 논문은 최근 감사원에 의해 모범선행사례로 선정된 무주 하천 1,2급 수해복구 건설사업관리 용역에 대한 CM성과를 분석하여 핵심성공요인과 Best Practice를 제공하는 것을 주요 목표로 한다. 본 CM용역에서는 무엇보다도 무주군내 수해복구공사에 CM 사업방식을 도입한 것은 현명하고 진취적이며 시기 적절한 일이라고 판단되며 이러한 선도적 기자체의 의욕적인 시도가 지방에서 수행되는 공공공사의 수준을 한 차원 높이는 계기가 됨은 물론 항구적인 복구공사기법의 하나로 정착하기를 기대한다. 또한 산업계는 CM관련 중심기관을 통하여 이러한 모범사례의 연속적인 분석과 보급을 통해 산업계 전반적인 CM수준을, 제고하여 국내외 CM확대 적용의 기반을 조속히 조성할 수 있기를 바란다.

The purpose of this paper is to develop a technical writing model suitable for engineering students based on the practice of technical writing using the patent application form for engineering students. The Dick & Carey model was used to design the teaching of technical writing using the patent application form. In particular, the instructor communicates with the learner and instructs the learner to produce and express students' own ideas. Instruction design in technical writing progresses consists of four steps, such as creating ideas by brainstorming, comprising contents, exercising writing, and feedback. Feedback occurs between an instructor and a learner and also does among students. As writing is proceeding step by step, instruction design for technical writing should come forth with specific methods to make students practice writing in work. Following these steps will help engineering school students to make up new products after graduating university.

The AEC industry is highly interested in effective ICT adoption and deployment, including its utilization within the design process. However, its capabilities have not yet been fully exploited and it is an obvious area for further research. Architects and engineers tend to have some technological support to monitor and evaluate the possible impacts of decisions made throughout the design process. Many aspects are left out of consideration and the entire project is broken up into independent fragments or domains that are combined together at a later, post hoc stage. Impact of separate decisions on each others have to be interpreted on a person-to-person basis between the involved design stakeholders. This paper attempts to evaluate current design practice and associated challenges towards design integration with advanced technologies, such as BIM, by conducting an online survey targeted at designers and engineers, who are most affected by its emerging issues. The outcomes of this study are presented and analysed, concluding that the current design process fails to meet expectations and needs improvements. It goes further to propose the requirements for an integrated system as a means for an effective solution for the identified problem.

In respond to the demand of an open, fair, transparent, and efficient environment for procurement, many governments have incorporated the use of internet in their procurement systems with online procurement (e-procurement). Given the different policies and laws which have to be complied with, the practice of government e-procurement system varies from one country to another. Thus, experiences in running e-procurement will vary as well. The achievements and obstacles of one country's experience will be a constructive reference for other countries in establishing e-procurement system. In this regard, government e-procurement system practices in two Southeast Asia countries i.e., Thailand and Indonesia particularly in public works are consecutively presented and finally compared in this paper. The government of Thailand has applied Online Auctions (e-Auctions) as the national procurement practice since 2005 and performed the e-Auctions in two types: Reverse Auction and Sealed Bid Auction. Contrary to the common practice of e-procurement, the Thai government, with some rationales, runs the bid documents obtaining manually as well as qualification and technical documents submission and holding the e-Auctions at bidding office. Whereas Indonesian government runs Online Sealed Bid Bidding (e-Procurement) and most of the bidding stages are performed electronically except bid evaluation for both technical and financial. The advantages and drawbacks of these two e-procurement practices are discussed as well as improvements that have to be made for successful of e-procurement.

As an activity of one working group for the Good Practice program at Kumamoto University, we proposed a questionnaire survey on the degree in which students understand the uppermost points of importance in their classes in addition to the usual type of class questionnaire. Each class lists three uppermost points of importance which are essential for understanding the class content. The degree of understanding is classified into four levels: full, most, insufficient, and not at all understandings. Through the analysis of questionnaire replies, the degree of understanding for bachelor students in the Department of Engineering was discovered to be meaningfully affected by the degree of difficulty, the effectiveness of audiovisual aids, self-study time, and class attendance.

Jilin Province is one of the principal production bases of traditional Chinese medicine (TCM) in China with its typical preponderance in TCM resources, research and development power, and industrialization capacity. The province has 2,790 species of TCM materials in total. Over 20% of the TCM materials in common use are from Jilin Province. The province has established 36 good agricultural practice bases for 22 typical TCMs. The overall situation, in terms of collection, processing, and preparation, and the implementation of good agricultural practice of TCM materials in Jilin Province are summarized.
