In a large number of literature on of inspection tasks, one of the most consistent findings is the existence of large and consistent differences among inspectors. It is possible that the individual difference is described by the difference of cognitive skills, because cognitive skills are required more than manual skills in inspection tasks. Therefore, a set of cognitive factors in human information processing may underly human performance in inspection tasks. In this study, a cognitive skill was described as the relative importance of the cognitive factors involved. A hierarchical task analysis and a fuzzy hierarchical analysis were used to represent how the importance of cognitive factors contribute to inspection performance. An experiment was conducted using the computer simulations of PCB inspection tasks. The results revealed that the subject group with better performance showed the importance weights of cognitive factors in the following rank; (attention, perception, judgement, classification, recognition)<(detection)$\ll$(memory). The results of the experiment can serve as a selection criterion for efficient inspection performance and the information of skilled learning for an inspection training program. The usefullness of a hierarchical task analysis and a fuzzy hierarchical task analysis for the analysis of cognitive tasks are also confirmed.

Due to economical or technological reasons. humans are responsible for inspection functions in many cases. Humans. however. are rarely perfect. thus allowing non-confirming parts to be processed. As the attributes of interest or the variety of products increases. the inspection system becomes less effective because of the sensory and cognitive limitations of human inspectors. Any means that can support or aid the human inspectors is necessary to compensate for inspection difficulty. Augmented reality (AR) offers a new approach in designing an inspection system as a means to augment the cognitive capability of inspectors by providing the 3D spatial proximity between two information channels. The experimental results suggest that AR might be an effective tool that reduces inspection time without sacrificing the measuring accuracy.

Currently rebar spacing inspection is carried out by human inspectors who heavily rely on their individual experience, lacking a guarantee of objectivity and accuracy in the inspection process. In addition, if incorrectly placed rebars are identified, the inspector need to correct them. Recently, laser scanning and AR technologies have been widely used because of their merits of measurement accuracy and visualization. This study proposes a technology for rebar spacing inspection and fixing by combining laser scanning and AR technology. First, scan data acquisition of rebar layers is performed and the raw scan data is processed. Second, AR-based visualization and fixing are performed by comparing the design model with the model generated from the scan data. To verify the developed technique, performance comparison test is conducted by comparing with existing drawing-based method in terms of inspection time, error detection rate, cognitive load, and situational awareness ability. It is found from the result of the experiment that the AR-based rebar inspection and fixing technology is faster than the drawing-based method, but there was no significant difference between the two groups in error identification rate, cognitive load, and situational awareness ability. Based on the experimental results, the proposed AR-based rebar spacing inspection and fixing technology is expected to be highly useful throughout the construction industry.

Due to recent enhance of safety law and regulations in construction sites, safety inspectors have been more required in construction sites. However, most of them are novice for safety inspection which have not enough experience and skill. Therefore, the novice safety inspector's performance on hazard recognition needs to be improved for effective safety management. The performance of safety inspection is influenced by the inspector's experience and background because the inspection is usually conducted by the inspector's eyes. Therefore, there is a difference in safety inspection performance between novice and experienced safety managers. This study aims to analyze the gap of risk perception between novice and experienced safety managers using quantitative visual data. For this objective, this study conducted eye tracking experiments for novice and experienced group to evaluate cognitive performance of safety risk factors. The results provides the level of safety awareness based on their experience in construction safety. The limitation of this study is a lack of the number of samples used in this study and did not consider the various characteristics of the participants. If these limitations are supplemented in future research, it can be used to develop safety education contents for novice safety managers.

세계화가 진행됨과 동시에 지역화가 이루어지면 지역문화에 대한 관심이 더 높아지고 있는 추세이다. 이러한 흐름에 맞춰 문화재청은 2016년부터 야간형 문화재 관광 콘텐츠로 '문화재 야행(夜行)' 사업을 추진하고 있다. 지역재생 사업의 일환인 문화재 야행은 지역의 문화유산을 중심으로 다양한 역사, 문화 관련 콘텐츠를 융·복합하여 새로운 부가가치를 창출한다. '문화재 야행(夜行)'이 크게 활성화 된 상황이지만, 지속적으로 이어가기 위해서는 변화가 필요하다고 판단된다. 고정된 야행 프로그램(8야(夜))이 전국적인 네트워크를 구축한다는 측면에서는 긍정적이지만, 획일화되어 다양한 형태로 확장하지 못하는 한계가 있기 때문이다. 이에 본 연구에서는 야행 프로그램의 의미와 한계를 파악하고, 야행 프로그램에 적용 가능한 인지시학 이론을 고찰하였다. 이러한 과정을 통해 인지시학의 '역동적 의미 구성을 위한 원형', '초현실적인 전경', '시간과 공간에서의 모험'이 야행 프로그램에 적용 가능하다는 것을 확인하였다. 실제로 인지시학을 야행 프로그램에 결합해 본 결과, 기존의 야행 프로그램과 차별화 된 야행 프로그램 구현 전략을 제시할 수 있었다.

Purpose: This study was conducted to identify the effects of a convergent web-based educational program on cognitive function, depression, and dementia prevention behavior among elders living in the community. Method: Participants were 16 elders over 65 years of age (8 in the experimental group and 8 in the control group). The educational program was given twice a week for 9 weeks. Results: Cognitive function and dementia prevention behavior improved in the experimental group. Cognitive function and dementia prevention behavior were reduced in the control group compared to the results of the pre-inspection; however, no statistically significant difference was found. As homogeneity test was not conducted previously for the assessment of depression, the assessment was conducted based on covariates, Although no significant difference found between the two groups, depression level did increase in the control group. Conclusion: Findings from this study indicate that the educational program prevented worsening of depression and was effective in reducing depression. For further assessment, it is necessary to conduct long-term research including a revision and supplementation of the contents and length of the program.
