This research examined how pilots perceive risks when faced with emergency flight situations. We had 116 commercial airline pilots evaluate riskiness of 39 non-routine flight situations. The pilots' risk perception was analyzed as a function of their position (captain vs. first officer), expertise (expert vs. novice), and military flight experience (with vs. without military experience). Results showed that captains evaluated potential-risk situations and low-risk situations more dangerous than first officers. However, there were no differences between experts and novices, and between pilots having military flight experience and pilots not having military flight experience in risk perception. The analysis of multi-dimensional scaling revealed that the pilots used controllability as a key dimension for evaluating riskiness, though the other dimensions they used varied with their position, expertise, and military flight experience.

This study was intended to investigate the influences of consumer's self-monitoring, pioneer brand awareness, types of endorsers on quality perception of "me-too" brands with a focus on outdoor brands. The design of this research was comprised of 2 types of self-monitoring(high vs. low), 2 types of pioneer brand awareness(high vs. low), 2 types of endorsers(professional expert vs. typical consumer). The study was carried out by using samples from residents of Seoul and Gyeonggi area. The number of subjects used in the final analysis totaled 243, with age of the consumers ranging grom 20's to 50's. The results of this study were as follows. Self-monitoring, pioneer brand awareness and types of endorsers had shown a statistically significant correlation effect on the quality perception of me-too brands. Especially, in the high-level self-monitoring group, the effect of pioneer brand awareness on quality perception of me-too brand was significant when typical consumer model was given. The result presents that using a professional expert model in the market rather than a typical consumer model can offset the quality perception of pioneer brand with low awareness.

Many studies have shown that having perception of spatial information is important for air traffic control officer (ATCO) since it helps them understand the current situation and predict the situation it leads to. However, little or no research has been done to investigate if there is any difference at the levels of expertise in perceiving spatial information and predicting a prospective situation. This study investigates the difference between expert and novice ATCO groups in how accurately each group of ATCO perceive spatial information such as position, altitude, speed, and flying direction, and predicting such information they will encounter shortly. In completing a task to watch the movement of airplanes displayed on the computer monitor as a blip, the participants were asked to predict the position, speed, and the altitude of the aircraft in a minute by marking on the sector map. The results show that the expert group performed better in accuracy and had tendency to overestimate on position and altitude; however, no significant difference was found between the two groups in terms of reading a flying direction. Therefore reading a flying direction may not be a reliable indicator to judge expertise of ATCO. But the expert group shows better predicting performance by perceiving spatial information such as airplane's position and altitude with feeling on time. The study suggests that it is important to enhance perceptive skills in ATCO training in improving their expertise in predicting accuracy traffic situation, preventing from air collision, and improving productivity for more efficient air traffic flow. A further study on the relationship between the perception of spatial information and the sense of time in predicting future information and effectiveness as an independent factor would contribute to providing more insights into expertise of ATCOs.

Purpose: The purpose of this study was to describe and understand elementary school health teachers' role perception in their own perspectives. Methods: Data were collected from three focus groups composed of five participants for each group. Each focus group had an interview for two and a half hours on the average. The main question was "What is your perception on the roles of health teachers in elementary schools?" Qualitative data from transcribed notes and field notes were analyzed using qualitative content analysis. Results: Five main roles were identified from the participants. The participants perceived themselves as 'an expert of health education in school and community', 'a health service provider for school members', 'a health guardian for school members, the coordinator of healthcare related works in school, and the leader of school health. Conclusion: The participants have multiple role identities, which are very important for health management of school members. And the roles such as an expert of health education and a leader for school health are recently emphasized. The findings of this study can provide useful information to design orientation programs for newly appointed health teachers and continuing education programs for enhancing role performance of health teachers in elementary schools.

There are enormous challenges in the Istanbul Strait- one of the most important, congested and narrow waterways in the world - from the view point of risk determination and risk mitigation for the local traffic. Previously several traffic parameters such as; traffic volume for local vessels, traffic flow and potential encounters of local traffic, in addition to the possibility of collision, were investigated in order to determine the degree of dangers in the southern entrance of the Istanbul Strait. Furthermore, risky zones were also determined in this waterway. On the basis of the results of those, a group of expert was surveyed. These experts were pilots, Vessel Traffic Services Operators (VTS-O), Local Traffic Vessel Captains and Master Mariners who had several experience of navigation through the Istanbul Strait. In order to assess experts perceptions of danger and to propose further studies based on this survey. The questionnaire was analyzed by using SPSS (Statistical Package for the Social Sciences) program version 13.0. Finally, some differences and/or shares on risk perceptions of expert in the Istanbul Strait are considered.

This study presents the new method which can transfer the expert's skill to deburring robot through neural network. The expert's skill is expressed as associationmapping between the characteristics of the burr and human expert's action. Under the fundamental idea that the state of the deburring processcan be extracted via the visual sense of the human,we employ vision system for the perception and identification of the changing burr. Form the demonstration of human experts, force data are measured. Finally the characteristics of the burr and coressponding force are associated by the neural network which is trained through many demonstrations. The proposed method is verified in the deburring process of welding burr.

To resolve the knowledge acquisition bottleneck in the expert systems, the connectionist expert systems have been proposed, which facilitate learning capability of neural networks. This paper is to modify Gallant's connectionist expert network so that it can be applied to more general problems : 1) The hidden nodes are added between the input nodes and an output node, so that the back propagation learning algorithm is used instead of perception based Pocket algorithm. 2) Inference engine is thus modified by modeling that a node may have uncertainties due to unknown inputs.
