A projection-based active information display system was proposed. The proposed system is based on Intelligent Space and a steerable projector mounted mobile robot which is called Ubiquitous Display (UD). In order to transfer visual information for a human in the Intelligent Space, the UD projects a certain shape of an image with a fixed size. Due to redundancy of degree of freedom (DOF), there are lots of situations to project a same shape and size of the image on a surface. In this paper, we describe a method to determine a goal posture of the UD. Here, the goal posture is the most efficient position and orientation of the UD so as to project visual information and it is determined by the Intelligent Space. To verify the proposed method, simulation and demonstration are carried out.

Best value in value engineering has relation to cost and performance. But a severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient and practical methodology for accomplishing best value in construction projects is proposed. This study developed a more objective approach for performance measurement approach of mega projects and suggested a systematic process of performance quantitative analysis verifying value improvement. The proposed performance measurement method would be very useful for better communication and consensus between stakeholders and VE team especially through value engineering.

With the growth of information and communication technologies adoption in construction projects, it could be anticipated that more property owners and construction firms will attempt to use electronic gears and gadgets for site monitoring or surveillance purposes. As the construction workers may be the major group of project team members being monitored, from managerial perspectives and for ethical reasons, it is essential to investigate their degree of acceptance on site monitoring systems. Indeed studies on office workplace monitoring suggest that a monitoring system could shape or control the behaviors of employees. With adequate refinements, their research models could be applicable in the construction industry. This paper presents a model for analyzing the antecedences that affect workers' acceptance level on electronic monitoring, and investigating if there is any behavioral change.

The evaluation items to assess the consumer needs are thought to be varied depending on their age, education and income. It should be noted that consumer needs are getting too diversified to notice them in time due to the rapid economic, social and cultural development. It is, therefore, considered improper to try to assess the level of consumer satisfaction and correct consumer needs by employing one evaluation method for the vastly diversified consumer types. This research is going to conduct a written questionnaire survey to the apartment dwellers in order to identify like dweller groups according to their age, income and education. Then the scope of personal characteristics of each group will be identified and the importance assessment model will be developed. Then the items on the POE will be weighted according to the assessed importance. Finally a method of developing the customer satisfaction index will be produced to quantify how much the consumers are satisfied with the project.

본 연구에서는 비 정보과 교사들의 효과적인 SW 교육 교수효능감 함양을 위하여 팀 프로젝트 기반 융합 교육 프로그램을 개발하였다. 개발된 교육 내용은 융합교육 및 팀 프로젝트에 대한 이해를 바탕으로 수학, 과학, 정보 등이 융합된 다양한 프로젝트를 실습한 뒤, 직접 문제 해결을 위한 프로젝트의 설계 및 개발과 발표, 동료 평가 및 피드백의 과정으로 구성되어 있다. 이는 10주간 비 정보과 교사들에게 처치되었고, 사전-사후 t-검정 결과, 통계적으로 유의한 향상을 나타내었다. 하지만 본 연구의 실험은 단일집단을 대상으로 하였기 때문에 추후 통제집단과의 비교를 통하여 향상에 대한 통계적 비교가 필요로 된다.

Detecting and assessing human-related risks is critical to improve the on-site safety condition and reduce the loss in lives, time and budget for construction industry. Recent research in neural science and psychology suggest inattentional blindness that caused by overload in working memory is the major cause of unexpected human related accidents. Due to the limitation of human mental workload, laborers are vulnerable to unexpected hazards while focusing on complicated and dangerous construction tasks. Therefore, detecting the risk perception abilities of workers could help to identify vulnerable individuals and reduce unexpected injuries. However, there are no available measurement approaches or devices capable of monitoring construction workers' mental conditions. The research proposed in this paper aims to develop such a measurement framework to evaluate hazards through monitoring electroencephalogram of labors. The research team developed a wearable safety monitoring helmet, which can collect the brain waves of users for analysis. A bispectrum approach has been developed in this paper to enrich the data source and improve accuracy.

본 연구는 신산업분야 특화 선도전문대학 지원사업 연구를 통해 개발된 CK-AR/VR PBL 교수법을 팀 프로젝트 기반의 캡스톤디자인 정규 교과목 수업에 적용해봄으로써, 해당 교수법의 장점 및 문제점을 파악하고 활용방안을 모색하기 위해 진행되었다. CK-AR/VR PBL 교수법은 기존 PBL(문제중심수업) 교수법의 특징과 장점을 유지하고 AR/VR 게임콘텐츠 특성에 맞는 특징을 중심으로 구축된 교수법으로 15주 정규교과목 수업인 '취업과창업을위한차세대게임창작프로젝트(캡스톤디자인)' 수업과 '취업과창업을위한차세대게임 포스트프로덕션(캡스톤디자인)' 수업을 수강한 200여 명의 학생에게 적용하였고 장단점을 파악하게 되었다. 이를 바탕으로 게임 개발 팀 프로젝트 교육과정을 운영 중인 교육 관계자들이나 앞으로 유사한 교육과정을 운영하기 위해 준비 중인 교육 관계자들에게 조금이나마 도움을 주고자 한다.

In this paper, we present unrecorded protozoans of Korea that were discovered, through the 'Discovery of Korean Indigenous Species' project hosted by the 'National Institute of Biological Resources (NIBR)'. A taxonomic account is provided for each identified species, offering comprehensive information such as species name, Korean name, collection site, synonyms, specimen vouchers, diagnoses, and figures. This study introduces 13 previously unrecorded Korean protozoan species that are classified into three phyla: Amoebozoa, Cercozoa, and Ciliophora. Notably, the cercozoan family Chlamydophryidae was recorded in Korea for the first time, together with the discovery of three previously unreported genera: Diaphoropodon within Cercozoa, and Metauroleptus and Hemicycliostyla within Ciliophora.

This paper deals with the design of the manufacturing information system which is able to respond rapidly to various requirements of customers in make-to-order environment. The system is required to maintain a consistent flow of information from the start to the end. For this, we adopt an approach based on Information Engineering (IE) methodology, which consists of four stages: planning, analysis, basic design, and detail design. The first is a planing stage which establishes a project goal and organizes a project team. In the second stage, current activities are analyzed and problems are defined. The basic design is accomplished in the third stage, where a project scope is defined and an overall feature of the new system is presented. And then, in the last stage, the operation plan of each subsystem is drawn up in detail and all subsystems are integrated. This study applies the methodology to the case of H company and focuses on designing forms which are easy-to-write, easy-to-understand, and field-oriented. These forms are interrelated and can be used for systematic analysis and design. By applying them to the system design, we have obtained effect of reducing cost and time.
