Will orange scent enhance video reality if it is presented with a video which vividly illustrates orange juice? Or, will romantic scent improve video reality if it is presented along with a date scene? Whereas the former is related to reality improvement when concrete objects or places are present in a video, the latter is related to a case when they are absent. This paper reviews previous research which tested diverse videos and scents in order to answer the above two different questions, and discusses implications, limitations, and future research directions. In particular, this paper focuses on measurement methods and results regarding acceptability of olfactory information, perception of scent similarity, olfactory vividness and video reality, matching between scent vs. color (or color temperature), and description of various scents using emotional adjectives. We expect this paper to help researchers or engineers who are interested in using scents for video reality.

This study was designed to examine the effect of depressive mood on identification of emotional facial expression. Participants were screened out of 305 college students on the basis of the BDI-II score. Students with BDI-II score higher than 14(upper 20%) were selected for the Depression Group and those with BDI-II score lower than 5(lower 20%) were selected for the Control Group. A final sample of 20 students in the Depression Group and 20 in the Control Group were presented with facial expression stimuli of an increasing degree of emotional intensity, slowly changing from a neutral to a full intensity of happy, sad, angry, or fearful expressions. The result showed that there was the significant interaction of Group by Emotion(esp. happy and sad) which suggested that depressive mood affects processing of emotional stimuli such as facial expressions. Implication of this result for mood-congruent information processing were discussed.

In this paper, we analyze the effect of the depth perception, volume perception and visual discomfort according to the change of the quality of the depth image and the depth of the major object. For the analysis, a 2D image was converted to eighteen 3D images using depth images generated based on the different depth position of a major object and background, which were represented in three detail levels. The subjective test was carried out using eighteen 3D images so that the degrees of the depth perception, volume perception and visual discomfort recognized by the subjects were investigated according to the change in the depth position of the major object and the quality of depth map. The absolute depth position of a major object and the relative depth difference between background and the major object were adjusted in three levels, respectively. The details of the depth map was also represented in three levels. Experimental results showed that the quality of the depth image differently affected the depth perception, volume perception and visual discomfort according to the absolute and relative depth position of the major object. In the case of the cardboard depth image, it severely damaged the volume perception regardless of the depth position of the major object. Especially, the depth perception was also more severely deteriorated by the cardboard depth image as the major object was located inside the screen than outside the screen. Furthermore, the subjects did not felt the difference of the depth perception, volume perception and visual comport from the 3D images generated by the detail depth map and by the rough depth map. As a result, it was analyzed that the excessively detail depth map was not necessary for enhancement of the stereoscopic perception in the 2D-to-3D conversion.

In Korea, the lower elementary grades are applying a topic-oriented integrated curriculum. It causes a lack of science content and inquiry experience for young children. The purpose of this study is to understand the scientific experiences and perceptions of the lower elementary graders and to inquire about the meaning of those experiences in their science learning. Four students (male 2, female 2), their parents, and their first-year homeroom teachers participated in the study. The data collection was mainly conducted through in-depth interview of them. Results showed that the 'experiments' were the student's the main perception of science, and the epistemic emotion that students mainly feel about science was 'curiousness'. Since most experiences were dependent on non-formal educational experience, the parents were an important factor to determine their experiences about science. Various factors, such as students' scientific experiences, their epistemic emotions, and the parents, interacted to form children's perception of science. The positive perception of science affected the level of motivation and expectation for science learning as the third grade. It is suggested that improvement of curriculum and textbooks should emphasize scientific exploration for the lower graders of elementary school, which provides them meaningful scientific experience in school.

Minimal architecture is generally expressed in a simple and pure form, this characteristic of minimal architecture was first introduced by the architect, Mies Van der Roche, in the beginning of 20th century. The objective of this study is to identify wether minimal architecture is just a reappearance of the beginning of 20th century's modern architecture or a suitable form for contemporary aesthetics. As a result, it can be concluded that minimal architecture is based on human emotion and one's experienced perception which is very different from the modern architecture which is more focused on functionality and mechanical esthetics. Minimal architecture uses two systems which are multi-sensual perception and conceptual perception; however, it focuses more on conceptual perception which is also used in comtemporary architecture. In conclusion, simplicity is just one of the necessary conditions which is not sufficient enough to represent minimal architecture.

The purposes of the study are to investigate Koreans' perception about Vietnam by analyzing social big data and to seek changing direction in perception. For the purposes, the texts about Vietnam in Naver Blog and Twitter and the number of search and click for Vietnam in Naver were analyzed by Social Metrics of Daum Soft and Datalab of Naver. The study also analyzed the annual change of their interest in Vietnam based on social media. The results showed that Koreans still remember the Vietnam war, have a positive emotion toward Vietnam, and view Vietnam as a country where we can gain mutual benefit by exchange. The findings also indicated that Koreans perceive Vietnam as a favorite tourist spot regardless of age. Meanwhile, children under 12 showed a different pattern of an annual change in perception. It might be a positive sign that Koreans' interest region toward Vietnam would be diversified because children under 12 would be the central axis of cultural contents.

The acting of physical action of the director Kang Yang Won's plays is mostly simple and repetitive. This acting induces the audience to sensuous perception and certain corporal emotions. In addition to semiotic meaning of dialogue a stimulus is given directly to sense of the audience. Therefore, the audience participate in creating a performative space with assistance of atmosphere. So, the feedback-loop of autopoiesis is made and the emergence of meaning is experienced due to felt perception. This emergent meaning springs unexpectedly by imagination, remembrance, and association etc. and is not produced on purpose. In addition, the audience participates in the performance together by the intersection of the perception for representation and perception for presence, and is especially affected by the presence of acting of physical action. In this paper, the study of four major performances of the theatre troupe Dong performed since the 2010s confirmed not only the individuality of each performance, but also the commonality that encompasses the entire performances. This led to discovering the discrimination power of the aesthetics of theater of the director Kang Yang Won and the theatre troupe Dong.

As a part of integrated study for technical communication between consumer and manufacturer of functional clothing, functional clothing consumers were categorized based on their perception of the functional outdoor jacket and the differences in the source of information and use of hang-tag were examined according to the groups. Questionnaire survey was conducted on 472 males and females in their 20s to 60s, who have experience of purchasing functional outdoor jackets. Perception of functional outdoor jackets was classified into four factors ('functionality', 'price', 'experience/knowledge' and 'brand/design') and the respondents were categorized into three groups according to the factors: 'unconversant/brand & design pursuing group', 'conversant/function pursuing group' and 'high-priced products preferring group'. 'Unconversant/brand & design pursuing group' was composed of high rate of office workers and students in their 20s and 30s who use internet most frequently as source of information while 'conversant/function pursuing group' was composed of high rate of professionals in their 40s and 50s who make the most frequent use of information on hang-tag. 'High-priced products preferring group', which has high rate of the elderly in their 60s and housewives, obtain their information mainly from salespersons. 'Unconversant/brand & design pursuing group' was satisfied with functional information more than other two groups and 'conversant/function pursuing group' concerned for the hang-tag and required more explanation of terminology used in hang-tag. The results effectively explained the features of consumer groups and their different responses toward the information of functional outdoor jacket.

LED technology offers versatile lighting control while having a very low environmental impact. Consequently, increasing attention is being paid to the emotional impact of LED lighting. This study investigated whether the chromacity of LED lighting influences people's time perception. To this end, two empirical studies were conducted: First, in experiment I(N=28), the subjects compared their perception of the time duration, which was varied from 3s to 20s, for 6 chromatically nuanced lighting conditions, respectively, with that under a daylight condition. The results showed that, in warm-color nuanced lighting conditions, the subjects perceived time to pass more slowly than in the daylight condition. On the contrary, in cool-color nuanced lighting conditions, the subjects perceived time to pass more rapidly than in the daylight condition. Then, in experiment II(N=39), the subjects were asked to count for 90 seconds while simultaneously performing some cognitive tasks. Confirming the results found in experiment I, the subjects perceived time to pass more rapidly in cool-color nuanced lighting conditions than in warm-color nuanced lighting conditions, although the difference was not statistically significant(p>0.05). In addition, the subjects tended to perceive the time to be shorter when the nuanced color of the light was closer to their preferred color.
