The purpose of this research was to determine whether multimodal cues in an online shopping environment could enhance tactile consumer mental imagery, purchase intentions, and attitudes towards an apparel product. One limitation of online retail is that consumers are unable to physically touch the items. However, as tactile information plays an important role in consumer decisions especially for apparel products, this study investigated the effects of multimodal cues on overcoming the lack of tactile stimuli. In experiment 1, to explore the product, the participants were randomly assigned to four conditions; picture only, video without sound, video with corresponding sound, and video with discordant sound; after which tactile mental imagery vividness, ease of imagination, attitude, and purchase intentions were measured. It was found that the video with discordant sound had the lowest average scores of all dependent variables. A within-participants design was used in experiment 2, in which all participants explored the same product in the four conditions in a random order. They were told that they were visiting four different brands on a price comparison web site. After the same variables as in experiment 1, including the need for touch, were measured, the repeated measures ANCOVA results revealed that compared to the other conditions, the video with the corresponding sound significantly enhanced tactile mental imagery vividness, attitude, and purchase intentions. However, the discordant condition had significantly lower attitudes and purchase intentions. The dual mediation analysis also revealed that the multimodal cue conditions significantly predicted attitudes and purchase intentions by sequentially mediating the imagery vividness and ease of imagination. In sum, vivid tactile mental imagery triggered using audio-visual stimuli could have a positive effect on consumer decision making by making it easier to imagine a situation where consumers could touch and use the product.

This is an experimental research with the theoretical background of agenda setting effect and elaboration likelihood model studying 'whether visual cues such as imagery and subtitle of TV environmental news have effect on the viewers' perception?', 'whether visual cues such as imagery and subtitle of TV environmental news have differential effect on the viewers' perception, depending on the viewers' involvement in the environmental issue?'. This experimental research found that the more highly exposed subjects considers environment issue more important than the less exposed, during the process, visual cues such as imagery and subtitle in TV news have an effect on agenda setting. Futhermore visual cues such as imagery and subtitle have stronger effect on the perception of the less involved than that of the more highly involved as a unified peripheral cue. However the effect of environmental involvement as independent peripheral cue couldn't have meaningful statistical support. Despite the fact that many previous researchers have shown that verbal cues of TV news have effect on the perception of viewers, little attempt has been made to investigate effect of visual cues on the TV viewers' perception. Therefore, this research has an important implication as an early proof in a new stream of visual agenda setting and elaboration research.

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.

Since we use internet every day, the internet privacy has become important. We need to find out what kinds of personal information is exposed to the internet and to eliminate the exposed information. However, it is not efficient to search the personal information using only fragmentary clues in web search engines because the ranking results are not relevant to the exposure degree of personal information. In this paper, we introduced a personal information retrieval system and proposed a process to remove private data from the web easily. We also compared our proposed method with previous methods by evaluating the search performance.

Prospective memory (PM) is memory for activities to be performed in the future, such as remembering to purchase a piece of fruit on the way home or remembering to give someone a telephone message. Theoretically, PM retrieval can be accomplished either by controlled monitoring of intended action or by a more automatic process that spontaneously responds to the presence of intended event. The present study examined the effect of meta-cognitive awareness in PM retrieval process. In Experiment 1, we manipulated PM condition with a salient cue to stimulate participants' meta-cognitive awareness. Results showed the salient cue condition spontaneously triggered remembering to perform an intended action. In Experiment 2, we manipulated participants' meta-cognitive awareness about PM task difficulty and about the degree to which cognitive capacity is required to realize the PM task. Results showed that PM retrieval process varied with meta-cognitive awareness (i.e., more resources were allocated if the PM task was expected to be difficult). These results imply that participants' meta-cognitive awareness play an important role in PM retrieval process.

Previous research have demonstrated that the external factors (ex., money, appearance) are more influential in Easterners' self-views and conditions for happiness than those of Westerners'. Based on these results, the current study examined whether 1) children and adolescents acquired these tendency as they grew up and 2) this tendency had relevance with social comparison. Total 954 students (260 elementary, 216 middle school, 260 high school and 218 college students) participated in the study. The results showed that elementary and middle school students regarded the internal factors (ex., thinking, feeling) as more important. But high school students considered the external factors as more important, and there was no difference in college students. Also, the results revealed that elementary and middle school students regarded the harmony of family and peace of mind as more important conditions for happiness. These results contrasted with preference for better educational backgrounds, better occupation, and money in high school and college students. In addition, age and social comparison tendency had positive relation with external self-concepts and negative relation with self-esteem. Especially, high school students showed strongest external self-concepts and social comparison tendency among four age groups. They also showed strongest preference for external conditions for happiness, but their self-esteem was the lowest. This might reflect fierce competition for college education in Korea, and the results of the current study have demonstrated that adolescents developed a tendency to prefer external factors to internal factors as they grew up in a competitive environment.

최근 들어 휴대성을 강조한 휴대폰이나 PDA 같은 다양한 모바일 기기의 등장으로 언제 어디서나 원하는 정보를 탐색할 수 있게 되었으나 기기는 점점 작아지는 반면, 기능은 증가하고, 많은 기기들이 데스크톱 인터페이스를 그대로 차용하여 작은 모바일 기기에는 적합하지 않은 결과를 낳고 있다. 따라서 본 연구는 청각 피드백을 이용한 공간정보 단서를 제공하여 작은 기기의 사용성을 높이는데 초점을 두고 있다. 이를 위하여, 실험 1에서는 두 가지 메뉴 구조에서 세 가지 청각 피드백의 영향을 조사하였는데, 격자메뉴와 한 줄 메뉴에서 각 청각피드백이 미치는 영향과 사용자의 선호도를 조사하였다. 실험 결과, 격자메뉴에서 수행이 좋았으나, 청각 피드백 유형별 수행 차이는 나타나지 않았고, 각 피드백에 대한 선호도에서도 차이가 나타나지 않았다. 실험 2에서는 실험 1에서 사용된 정보를 제공하는 청각적 피드백을 음 높이와 음의 개수 속성으로 세분화하여 PDA에서 메뉴 탐색 수행을 4블록으로 나누어 조사하도록 설계하였다. 실험 결과, 음 높이 속성만 갖는 피드백은 블록이 진행되면서 반응 시간에 있어서 피로도가 나타난 반면, 음 개수 속성만 갖는 피드백은 블록이 진행되어도 피로도가 나타나지 않았다. 한편, 두 속성을 모두 갖는 피드백은 블록이 진행되면서 보행 속도가 유의미하게 줄어드는 것을 발견하였다. 본 연구의 결과는 앞으로 유비쿼터스 환경에서 사용자에게 효율적인 청각 피드백을 통해 공간 정보를 제공함으로써 휴대기기의 사용성을 높일 수 있는 한 가지 가능성을 제시한다는 데 의의가 있다.

The purchase-related responses of MZ generation consumers may vary depending on the environmental factors of the fitting room. Therefore, this study extracted and systematized fitting room characteristics in the retail fashion environment. In-depth interviews were conducted with a total of 50 informants to collect data on the experience of using the fitting room. Then, a qualitative analysis was performed. First, results confirmed that the environmental factors of the fitting room include physical (spatiality, functionality, comfort, and convenience) and human (interactivity and congestion) aspects. Next, additional analysis was performed on functionality and interactivity to clarify the influence of environmental characteristics of the fitting room. These factors were classified into qualitative categories. The study results confirmed that, in the case of functionality, preferred lighting and mirror factors vary depending on the clothing product type, the place and situation for wearing, and individual characteristics. Furthermore, regarding interactivity, the preference for the presence of sales staff or companions differed according to personal traits and the need for additional information and evaluation. The study provides valuable information for effective fitting room space planning for offline fashion stores to meet the needs of MZ generation consumers.
