Previous research has mainly investigated the characteristics of expertise by using typical and routine tasks. This research to overcome these limitations included non-routine task situations and observed expert and novice pilots' situation awareness (SA) performance in routine and non-routine situations. Additionally, whether the ability to aware or perceive the environmental information in limited time varies with the level of expertise was tested. To this end, $2^*2^*2$ mixed factorial design was employed, including expertise (novice/expert) as a between-subjects variable and normality of fight situation (routine/non-routine) and stimulus display time (long/short) as within-subjects variables. As results, there was no performance difference in routine situations between experts and novices, while experts significantly outperformed novices in non-routine situations. When the display time became shorter, overall SA accuracy was decreased for both experts and novices, whereas experts' performance remained significantly higher than novices in short and long conditions. When we examined the interaction between the normality of fight situation and stimulus display time, there was no difference between experts and novices in routine situations for both short and long conditions. In non-routine situations, however, experts' SA accuracy was significantly higher than novices both in short and long conditions. Overall, non-routineness of flight situation does not have any impact on SA performance of experts, while it has a critical impact on SA performance of novices.

The globalization of Korean culture has spurred a steady increase in the participation of domestic fashion designers in global performance art. This study analyzes the formal elements of stage costume designs by fashion designers, and further evaluates the impact of these designers' aesthetic philosophies on overall performance. This analysis seeks to provide a foundation for the development of new directionality in performance art, with an enhanced competitiveness derived from diversity and creativity. The scope of this research spans 15 performances and eight fashion designers' works in the post-2010s era. These performances are characterized by their break from traditional artistic norms, illustrating the modernization of the performing arts and reflecting the designers' aesthetic philosophies. This modernization incorporates inspirations drawn from a diverse selection of movements, such as fusion, culture clash, kitsch, and minimal avant-garde. As a result, in combination with a pure reflection of the designers' aesthetics, these designs heighten overall performance, suggest a new direction for traditional performance art, tap into a popular sensibility to expand communication to a wider audience, and push the boundaries of tradition through artistic innovation.

Lighting industry is rapidly being developed as the ubiquitous society based on sensor network emerges. This kind of paradigm shift brings the society convergence of technologies which leads to smart lighting system as well as the integration of interior and sensibility control. However, standards for sensors have not been firmly established, and problems related to quality and malfunction have been brought up, thereby calling for careful approach to the enhancement and assessment of reliability of the item. In this article reliability assessment criteria for sensor module for lighting fixtures is established in terms of performance assessment criterion and reliability assessment criterion.

To review mass transfer trays from a process of view, the dependence of efficiency in loading ranges and maximum loadings with an acceptable efficiency of traditional tray have to be known. It is reported about the performance of the metallic Dualflex, relatively new high performance packing. Absorption, desorption and rectification tests as well as pressure drop and maximum capacity are concerned, indicate the superiority of the Dualflex over the general packing of comparable, main process. The process engineering characteristics show that Dualflex can be applied for all mass transfer precesses and it is to be recommended especially for those high capacity separations which requite allow low pressure drop because of the thermal sensibility of the product or because of the need of energy saving.

The purpose of the present driving simulation study was to examine the effect of cellular-phone use on driving performance when required driving speeds were systematically varied(60, 80, 100, or 120km/h) while either using cellular-phones(experimental condition; Hands-Free or Hands-Held) or not(control condition). Driving performance was measured both by longitudinal vehicle control(i.e., variabilities in driving speed and headway) and lateral vehicle control(variabilities in lane position). The results can be summarized as followings: (1) The significant difference in driving speed variation between the two cellular-phone usage conditions was found only at relatively higher driving speed conditions(i.e., over 80km/h). (2) Only in the experimental condition where cellular-phone was required to be used while driving, the magnitudes of variation in driving speed, headway and lane position were gradually increased as the required driving speeds were increased(this tendency was not found in control condition). And. (3) the dependent measures of this study appeared to suggest that cellular-phone usage itself (rather than the types of cellular-phone) had significant impact on driving performance. Finally, implication and issues related to this study were discussed.

Site-specific performance is always the real on-site work taking place at the site. Hence, it deals with the reality, in other words, the time of creation and formation. And it creates value and meaning through the interaction and continuous direct communication process between the performers, audience and the local residents. In this performance, the audience's status as the passive observer changes. They become the co-agent who actively lead and complete the performance through their own experience. We have examined the The Working Methods of Site-specific Performance and Aesthetics of Effect through four Korean performances ; Marie, An aesthetic experiment of site as the storyteller; Heterotopia and Urban Movement Research or Play: We Will Move Your Sofa, as performances which have Revealed history, politics, institution engraved in the site ; A Song of Mandala and Miracle, as a ritualistic site-specific performance at the historic site. Some remarks on Site-specific performance ; First, In Site-specific performance, the habitus peculiar to the stage art and the mode of reception are changed. Second, a new mode of theatrical communication requires creator and audience to have a sharp aesthetic sensibility and to change one's perceptual habit. Third, Site-specific performance can act as a demonstration for the viewpoints of political activism through what could be called a dramatic close-up effect. Fourth, Site-specific performance also has the risk of merely becoming an unfocused and scattered performance or degenerating into a pseudo-sightseeing. To avoid this, an in-depth study of the site and its socio-cultural context, and the clear motivation with which one is trying to reveal and tell from the site must be indispensable. As the co-agent, the audience should also be aware and think about what the given performance signifies today.

We examined the effect of delayed and immediate rewards on short- and long-term memory performance depending on the level of stress. It has been demonstrated that delaying feedback during memory tasks could lead to better retention than presenting it immediately (a.k.a., feedback delay benefit or delay-retention effect). In this study, we manipulated stress level(high-stress or low-stress), reward-timing(delayed or immediate reward), reward-existence(500 or 0 won) and retrieval-timing(delayed or immediate memory test). On the high-stress learning condition, one week later, the number of correct answers with delayed-rewards were significantly more than that of delayed-no-rewards but there was not any difference between immediate-rewards and immediate-no-rewards. On the other hand, in the high-stressful immediate memory test, immediate-rewards only had a positive effect on memory performance. The results indicated that delayed rewards improved long-term memory performance by promoting memory consolidation and the sensitivity to rewards was higher under the high-stress condition.

PET fabric is used as a regular clothing in the middle-east region which is called Chador as a women's clothing and Thobe as a men's clothing. Then there is a big difference of export price according to the minute hand characteristics of the PET fabrics, of which characteristics are due to the fibre and manufacturing process characteristics. This research surveys the optimum manufacturing conditions related to the fibre and fabric for the Thobe clothing which were developed in this study through comparison with high price Teijin Thobe manufactured in Japan. In this research, four kinds of Teijin fabrics made in Japan were prepared as a target quality specimen, and five kinds of developed fabrics were produced as an experimental specimens. These specimens were made by changing yarn denier, twist, yarn setting conditions and fabric density, which are also changed by twist contraction, weaving and finishing shrinkages. As a result of this study, the sensitive characteristics of Teijin Thobe fabrics can be analysed from fibre and fabric, and then the manufacturing design technology was constructed under the base of low twist texturing and 3 dimensional fabric design simulation technologies.
