This study aimed to investigate the correlation between speaker's chronological age (CA) and perceived age (PA) and to specify the effect of pitch and speech rate as acoustic cue on judging age, using perceptual testing and acoustic analysis. Three tasks were conducted to identify the degree of listener's accuracy about age estimation. Three perception tasks were conducted to measure the accuracy of 80 Korean listeners when presented with different types of speech. In all the tasks, participants listened to speech samples and gave their estimate of the speaker's age in figures. It was found that Korean listeners are able to gauge the age of a speaker fairly precisely. CA and mean PA were positively correlated in all three tasks. It is clear that the amount and type of information included in the voice samples affected the accuracy of a listener's judgement. Moreover, the result revealed that listeners make use of acoustic information such as pitch and speech rate to estimate speaker's age.

Luxury products are sold in various online shopping malls in China. Companies utilize celebrities as their advertising models or disclose their CSR information to lower perceived risk. This study scrutinized the effects of CSR information and celebrity models on the relationship between perceived risk and the intention to use online shopping malls. According to the elaboration likelihood model, when consumers perceive high risk, they use the central route to process information and form attitudes. Celebrity models and CSR information as secondary clues may not have a significant effect. To test the hypotheses, a 2 (risk H/L)×2 (CSR)×2 (model) factorial design was employed. Study results found in a low perceived risk situation, CSR information or a celebrity model endorsing their products significantly increased the intention to use the shopping mall (model w/ 3.407 vs. w/o 2.88; CSR w/ 3.29 vs. w/o 2.779). However, in a perceived high-risk situation, their effects were not significant. Therefore, it is noteworthy that celebrity models and CSR information are effective in increasing the intention to use online shopping malls only when consumers use peripheral routes in a perceived low-risk situation.

This study aimed to reveal how Vietnamese adult learners at three different proficiency levels perceive Korean word-initial obstruents and whether errors can be corrected through perceptual training. To this end, 105 Vietnamese beginner, intermediate, and advanced learners were given perceptual training on Korean word-initial. The training materials were created by actively utilizing Korean minimal pairs as natural stimuli recorded by native speakers. Learners in the experimental group performed five 20-40 minute self-directed perceptual training sessions over a period of approximately two weeks, while learners in the control group only participated in the pretest and posttest. The results showed a significant improvement in the perception of sounds that were difficult to distinguish before training, and both beginners and advanced learners benefited from the training. This study confirmed that large-scale perceptual training can play an important role in helping Vietnamese learners learn the appropriate acoustic cues to distinguish different sounds in Korean.

The conclusions shown by this study are as follows: Firstly, Despite the similarity of the objective distance caused by the geographic distance and cultural similarities. it is found that the psychic distance factor still exists. Secondly, a new affective factor of psychic distance has been noted. As to the shaping method, even though culture and psychic distance involve homeogenic factors, psychic distance is more complex in that it is affected not only by cultural changes but also by other affective factors. Culture is a very significant factor, which can have an effect on forming psychic distance, but it is short of being a measurement variable for measuring psychic distance. Thirdly, psychic distance can have a direct effect on customers' buying response. If it is just a belief shared among the people of a nation, it can't become an important notion.

동물계의 몇 곤충을 제외한 대부분 두 개의 눈을 가지고 시 생활을 하게 된다. 이런 두 개의 눈은 진화 과정에서 생존을 위해 필요 충분한 요인인 것이다. 눈의 시야계의 역할을 주변에서 일어나는 사항에 대해서 생존을 위한 즉각적인 대처를 할 수 있게 하고 주변 환경에 대한 정보를 정확하고 빠르게 수용하기 위한 것이며, 외부 환경의 3차원 세계의 정보를 지각하기 위한 것이다. 사람이 볼 수 있는 수평각은 $210^{\circ}$로 다른 동물에 비해 가장 작은 값을 갖으나, 두 눈을 동시에 한 사물을 관찰 할 수 있는 3 차원적 지각 각도는 $130^{\circ}$로 다른 동물에 비해 가 장 큰 값을 갖고 있다. 이런 현상은 사람에게 3차원 영상의 수용이 가장 진화된 것으로 이와 관련된 입체시와 양안 불일치의 형성 원리를 설명 할려고 한다. 양안 불일치는 양 눈과 관련되기 때문이다. 이런 단서는 두 눈은 서로 다른 위치에서 세계를 보기 때문 외부 세계에 대해서 두 개의 약간 서로 다른 시점을 가진다 라는 사실에 기인한다.

This study aimed to identify the differences in pitch perception between tonal and non-tonal language listeners. A total of 60 Korean and Chinese listeners participated in the perception test. A two-syllable nonsense word /paba/ was manipulated in five steps. The pitch height or contour on the second syllable was raised or lowered. Both groups were asked to select which of the two syllables had the higher pitch. The findings showed that the majority of Korean listeners (GK) perceived decreased pitch as each peak of the syllable was lowered and perceived increased pitch as it was raised, which means the pitch height is a primary perceptual cue for GK. However, Chinese listeners (GC) perceived sensitive pitch movements as the pitch contour changed. GC's perception may presumably be affected by the L1's tone sandhi. We found it reasonable to assume that language experience has a significant effect on the cross-linguistic perceptual differences between tone and non-tonal language listeners.

The perceived quality is a concept considered from the consumer's perspective. So it is differ from the objective determination of product quality. Thus the consumer perception of quality is a subjective judgement of an individual and an overall feeling on the characteristics which includes the product's reliability, performance and so on. In terms of product perception, consumers utilize the product cues in evaluating the product's quality before the purchase and the cues reflecting the quality can be classifisied into intrinsic and extrinsic ones. When the quality perception is limited to the purchase situation, purchase decision dependent on surrogate indicators such as price, are inclined to increase due to the lack of information. Therefore in this study the perceived quality of apparel is controled to the purchase situation in order to examine the consumer's reaction to the price cues and for the convenience of the exploratory investigation. As a result of the empirical study, consumers show differences in quality and value perceptions to the product with the same price depending on the perception whether the price is high or low. The apparel quality evaluation process goes through the steps of "product attributes - perceived quality - perceived value - purchase intention".

This paper is a reflective study of contemporary Korean scholars' claims that they criticize the explanation of Zhu Xi(朱熹, 1130-1200)'s psychology in which he explains that the 24th Hexagram of $F{\hat{u}}$[復卦] shows the state that the mind has not happened yet[未發]. Zhu Xi explains the 24th Hexagram of $F{\hat{u}}$[復卦] with the theory of no mind yet[未發說]. Several scholars in modern Korea, however, raise the question of whether "thoughtless[思慮未萌] but being not dark to perception[知覺不昧]" of the 24th Hexagram of $F{\hat{u}}$ is enough to explain the state of no mind yet. And they think that "thoughtless[思慮未萌]" is appropriate to explain the state in which the mind has not yet occurred, but it is not to "being not dark to perception". In this study, we would like to show that Zhu Xi's interpretation of the 24th Hexagram of $F{\hat{u}}$[復卦] fully explains the fact that "thoughtless[思慮未萌] but being not dark to perception[知覺不昧]" explain the theory of no mind yet[未發說]. Zhu Xi's 'the theory of no mind yet[未發說]' is divided into two periods, a period of 'old theory on $zh{\bar{o}}ngh{\acute{e}}$[中和舊說]' and a period of 'new theory on $zh{\bar{o}}ngh{\acute{e}}$[中和新說]'. He develops 'the theory of no mind yet[未發說]' on the basis of 'the theory that nature is body and mind is action[性體心用說]' during the period of old theory, and develops the theory[未發說] based on 'the theory that mind controls nature and feelings[心統性情說]' during the new theory. Between the two periods, the status of the mind changes from "the mind has already happened[已發]" to "through which the mind has not yet arisen and the mind has already risen[未發已發]". And its role also changes from 'what nature is happened' to 'presiding on nature and emotion.' This change affects the interpretation of the idea that the mind has not yet happened, that thoughts have not budged yet[思慮未萌], perception is not dark[知覺不昧].

We investigated whether human could perceive the heading direction from the optic flow made from random dots and real images simulating the motion of the observer and objects. When an object moves across the focus of expansion(FOE) in random dot simulation. the observer perceived the focus of expansion biased toward the motion direction of the object. supporting the hypothesis that the direction repulsion is produced between the expansional and the horizontal planar motion components. With real image display observers tended to perceive one's heading direction biased toward the c center of the scene regardless of the direction and position of moving 0bcts. And it was observed that the deeper the depth of the background was the larger the judgment error was. These results suggest it is more likely that human depends on different cues than the optic flow when they perceive or judge one's heading direction in the real environment.

This study intends to make a proposal the direction classification to develop the independent study of e-book's visualization. For this, we research into the e-book of Disney animation which achieved recognition in the literary value and amusement First of all, We grasp the meaning of the concept of e-book's aerial-image and perceptual principle. Next, We found the subject that starts the movement, and then observed the factor of the presentation to be possible to experience the actual spatial experience by the motion-produced cues. Through analysis process, We can classify the appearance elements, media, camera, and the readers' motion-produced cues into 13 parts and define as the codes. As we analysis the frequency of use of the analysis object, We separated it into the 46 combination exercises. According to the combination with the independent exercise, We separated them into 4 groups. There are the actual spatial experience, narrative spatial experience, the experience of characters. The basis for these, we can analyze the characteristics of the motion-produced cues. This study has the meaning of the expansion of e-book into the film language system by separating the e-book's narrative visualization type.
