The purpose of this study is to investigate the effect of eyeshadow color(brown, purple), lipstick color(red, red purple, and yellow red), and lipstick tone(vivid, light, dull, and dark), clothing color(same, different), clothing tone(vivid, light, dull, and dark) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 128 color pictures manipulated with the combination of eyeshadow color, lipstick color, lipstick tone, clothing color, and clothing tone using computer simulation. The subjects were 768 female undergraduates living in Gyeongnam-do. Image factor of the stimulus was composed of 4 different components, attractiveness, visibility, stability, and softness). In the 4 image components, lipstick tone, clothing color and clothing tone showed independent effect. Eyeshadow color influenced independently on the attractiveness, visibility and stability. According to the variation of clothing color and tone, makeup color, it was investigated that the images for a clothing wearer were expressed diversely, were shown differently in image dimensions, and could be produced to different images.

The purpose of this study is to investigate the effects of eye shadow color(brown, purple), lipstick color(red, red purple, and yellow red), and lipstick tone(vivid, light, dull, and dark) and clothing tone(vivid, light, dull, and dark) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli consisted of 64 color photos manipulated with the combination of eye shadow color, lipstick color, lipstick tone, and clothing tone using computer simulation. The subjects were 384 female undergraduates living in Gyeongnam Province. Image factor of the stimulus was composed of 4 different components: attractiveness, visibility, cuteness, and stability. Eye shadow color, lipstick tone and clothing tone independently influenced on visibility, cuteness, and stability. Lipstick color independently influenced on the stability. In color coordination of clothing and makeup of the same hue, 1) visibility image can be created by the coordination of eye shadow color with lipstick color or clothing tone, or lipstick color with lipstick tone. 2) Cuteness image can be produced by the coordination of eye shadow color with lipstick or clothing tone, lipstick color with lipstick or clothing tone. 3) Stability image can be showed by the coordination of eye shadow color with lipstick tone.

본 논문은 2D 애니메이션 캐릭터의 자동 색 지정을 위하여 애니메이션 장면간의 캐릭터 색 변환 기술에 대해 제안한다. 사람이 지각하는 색은 조명이 달라지면 다른 색으로 지각된다. 이와 마찬가지로 애니메이션 장면에 등장하는 캐릭터도 의상, 피부 등의 색이 장면 분위기에 따라 각각 다르게 지정되고 있다. 본 논문은 이러한 2D 애니메이션 장면간의 캐릭터 색 지정을 수작업에 의존하지 않고 수학적으로 해결하기 위해 시도한 것으로써 조명에 따른 색 원리를 이용하여 장면간의 캐릭터 색 변환을 위한 행렬을 유도하였다. 이 색 변환행렬은 애니메이션 장면마다 각각 구해지는데, 기존의 2D 애니메이션에 등장하는 동일캐릭터의 기본색과 각 장면속의 색을 이용해서 구해진다. 이렇게 구한 색 변환행렬은 어떠한 캐릭터의 기본색만 주어진다면 다양한 장면 분위기와 잘 어울리는 색으로 변환이 가능해진다.

The influences of luminous environment on visual responses and fatigue sensation in art galleries were examined in this study. Field measurements and survey were performed in three galleries under various illuminance and luminous conditions. Result implies that vertical illuminance on art paintings needed to be somewhere between 200 lx and 300 lx to avoid visual discomfort. The vertical illuminance difference between consecutive paintings should not exceed 100 lx to keep visually comfortable environment. Visual comfort sensations were related to glare, visual stimulus, reflection from paintings, illuminance variation, and the sensation that subjects can clearly see the paintings. The sensation of fatigue was significantly influenced by the changes of luminous element that caused visual stimulus and discomfort. The sensation of eye fatigue among physical fatigue was primarily influenced by the glare, visual stimulus and comfort. The psychological fatigue was also influenced by eye fatigue, visual comfort, brightness and satisfaction with color of light.

Background and Objectives: The aim of this study is to evaluate the effect of music training on the characteristics of auditory perception of speech and music. The perception of speech and music stimuli was assessed across their respective stimulus continuum and the resultant plots were compared between musicians and non-musicians. Subjects and Methods: Thirty musicians with formal music training and twenty-seven non-musicians participated in the study (age: 20 to 30 years). They were assessed for identification of consonant-vowel syllables (/da/ to /ga/), vowels (/u/ to /a/), vocal music note (/ri/ to /ga/), and instrumental music note (/ri/ to /ga/) across their respective stimulus continuum. The continua contained 15 tokens with equal step size between any adjacent tokens. The resultant identification scores were plotted against each token and were analyzed for presence of categorical boundary. If the categorical boundary was found, the plots were analyzed by six parameters of categorical perception; for the point of 50% crossover, lower edge of categorical boundary, upper edge of categorical boundary, phoneme boundary width, slope, and intercepts. Results: Overall, the results showed that both speech and music are perceived differently in musicians and non-musicians. In musicians, both speech and music are categorically perceived, while in non-musicians, only speech is perceived categorically. Conclusions: The findings of the present study indicate that music is perceived categorically by musicians, even if the stimulus is devoid of vocal tract features. The findings support that the categorical perception is strongly influenced by training and results are discussed in light of notions of motor theory of speech perception.

This paper has identified some theoretical reasons and empirical evidence for negative scores that occur in Japan and Korea or unstable NPS scores that can be experienced. A psychological analysis of NPS results sheds light on the validity of the negative NPS scores that are often found in Japan and Korea. Usually customer experience surveys utilize a "single stimulus" such as the "company" or the "company's products / services." However, in the case of the "recommendation to friend" question of the NPS system there are two stimuli namely the "company product/service" and the influence of "friends." Hence, the survey outcomes from this question can be very different when compared with other single stimulus questions such as "overall satisfaction" or "repurchase." Japanese and Korean people may have a positive attitude towards the company but they will provide low NPS scores because they are reflecting that they would not run the risk of ruining their relationships with their friends by making a recommendation. As a result, in the NPS system these people will be labeled as "detractors" when in fact they are "ambivalent customers." Using several Japanese and Korean based marketing research industry examples and case studies, different strategies are proposed to address the issue of negative scores in the NPS system in Japan and Korea. The Customers Psyche appears to be the key determinant factors for both types of behavioural items (items with a single stimulus as well as items with two stimuli).

When the light stimulus was presented continuously, habituations were formed, after 13 and 14 hrs in amoeba and planaria, repectively. As amoeba more habituated, the light-escaping velocity of streaming was decreased with a negative-exponential function. in two-dimensional electrophoretic patterns of proteins of amoeba habituated, a newly synthesized protein (pI 7.0, MW 20 kD) was detected. Therefore, it is conjectured that similarity or commonality may exist between amoeba and planaria habituations to light, and in these behavioral modifications, specific protein(s) may be involved in molecular level.

Artificial neuromorphic devices are considered the key component in realizing energy-efficient and brain-inspired computing systems. For the artificial neuromorphic devices, various material candidates and device architectures have been reported, including two-dimensional materials, metal-oxide semiconductors, organic semiconductors, and halide perovskite materials. In addition to conventional electrical neuromorphic devices, optoelectronic neuromorphic devices, which operate under a light stimulus, have received significant interest due to their potential advantages such as low power consumption, parallel processing, and high bandwidth. This article reviews the recent progress in optoelectronic neuromorphic devices using various active materials such as two-dimensional materials, metal-oxide semiconductors, organic semiconductors, and halide perovskites
