People's thinking and aging ways, which are spread in the abnormal situation called the reoognition panic, are different from those in the normal situation. So the design which is applied to this situation have the different points to be considered. The design in the abnormal situation is as important as that in the normal situation. This study is to evaluate the basic usability of the icons which are applied to this situation. The basic data about the recognition course, icon and metaphor have been collected and analyzed, and then the experiments based on this have been planned. The proprieties and conclusions about the ways have been generalized through accomplishing and analyzing the planned experiments. The most important meaning of this study is to suggest the examples of the usability estimating ways of the design works in the abnormal situation where the recognition panic may happen with high frequency. I hope that this study will be used for checking and improving in advance the difficulties of using the design which may happen in the real situation, by using actively the similar ways to this experiment.

This study was conducted to investigate the possibility of using gaze entropy to evaluate an operator's situation awareness in an emergency accident situation of a nuclear power plant. Gaze entropy can be an effective measure for evaluating an operator's situation awareness at a nuclear power plant because it can express gaze movement as a single comprehensive number. In order to determine the relationship between situation awareness and gaze entropy for an emergency accident situation of a nuclear power plant, an experiment was conducted to measure situation awareness and gaze entropy using simulators created for emergency accident situations LOCA, SGTR, SLB, and LOV. The experiment was to judge the accident situation of nuclear power plants presented in the simulator. The results showed that situation awareness and Shannon, dwell time, and Markov entropy had a significant negative correlation, while visual attention entropy (VAE) did not show any significant correlation with situation awareness. The results determined that Shannon entropy, dwell time entropy, and Markov entropy could be used as measures to evaluate situation awareness.

Situation awareness is defined as a person's perception of the elements of the environment within a volume of time and space, the comprehension of their meaning and the projection of their status in the near future. Situation awareness is important in attempting to evaluate human behavior in operating complex systems such as aircraft, air traffic control, and nuclear power plant systems. From the literatures this study reviews the relationship between situation awareness and numerous individual, system and environmental factors, and also reviews the methodologies for the empirical measurement of situation awareness applicable to Korea Next Generation Reactor (KNGR) design project. Attention, working memory, workload, stress, system complexity, and automation are presented as critical factors limiting operator's situation awareness. Mental models and goal-directed behavior are hypothesized as important mechanisms overcoming these limits. This study summarized hypothesized guidelines for interface design to improve situation awareness of reactor operators. Some of the guidelines should be tested in the KNGR evaluation experiments in the future.

The situation recognition can be implemented by configuring several situation in the school zone system. Such the recognized situations can use the result informing to the event through appropriate output format. In this paper, we propose the design scheme of situation output in the school zone system.

The specific purpose of this was to investigate if ir was feasible to design and execute garments that were multi-functional in purpose for women living in an expended world of social and occupational interaction which rerequired flexibility and convenience in their clothing appropriate to their multiple roles in society. The study was to carry out based on the selected situations(business situation-social situation and private situation-social situation) and designs deduced from the situations. The garments could permit flexibility in style through adjustable features which could be attached to, or detached from, the garment depending on the occasion and need of the wearer. As the results of the study, the characteristics of multi-functional garments were found as follows : First, the garments could bring about flexibility in garment formation through adjustable details, overlay and patch, in order to increase the multi-functional usage of the garments. Second, the style of garments could be expressed design images to meet the needs of flexibility and convenience for the various occassions. Third, the multi-functional garments could meet the needs for time and economic values for the women who play multple roles.

The college students selected by random sampling were classified into four groups by their body cathexis and clothing attitude to investigate differences in the consumer's Impulse-Buying in a negative consumer situation. Consumer cluster were classified into four groups: positive congruity(G1), positive incongruity(G2), negative congruity(G3), negative incongruity(G4). The result are as follows: G1 had high impulse. After Impulse-buying in a negative consumer situation they had negative attitude. G2 tends to do Impulse-buying a lot in a negative consumer situation. G3 had low impulse. After impulse-buying in a negative consumer situation they had both positive and negative attitude. After impulse-buying, G4 had negative and they tend to do a pure impulse buying in a negative consumer situation. As a result, the buying-impulse could cause the impulse-buying.
