본 연구에서는 가상현실을 이용한 단서노출치료가 흡연자의 니코틴 갈망수준을 감소시키는지를 알아보았다. 이를 위하여 8명의 흡연청소년을 대상으로 6회기의 가상환경 단서노출치료를 실시하였다. 또한 단서노출치료 실시전과 후에 흡연관련 사진과 중립사진을 제시하는 동안 참가자들의 뇌를 기능성 자기공명영상장치(fMRI)로 측정하였다. 그 결과 단서노출실시 전에는 prefrontal cortex(PFC), Anterior cingulate gyrus(ACC) 영역을 비롯한 7개의 영역이 활성화되었고, 단서노출치료 후에는 right middle frontal gyrus, right uncus, left medial frontal gyrus, right fusiform gyrus, 그리고 right superior frontal gyrus 영역이 활성화되었다. 단서노출치료 전과 후의 비교에 서는 PFC가 관찰되었다. 본 연구의 결과로 흡연자의 흡연 갈망은 감소되었으며, 가상현실단서노출치료는 흡연자들 뿐 아니라 여러 물질의존자들의 치료에 유용한 방법이 될 것이라는 것을 시사한다.

The purpose of this paper is to show their distinctive auditory cues. Until now research of acoustic characteristics has been confined to simple experiments concerning the restricted conditions. Therefore this paper examines all of the acoustic characteristics of the lax and tense Fricative Consonants and shows to how acoustic characteristics can be used to differentiate lax and tense Fricative Consonants. The results of this paper are (a) auditory cues are especially important if there is a large difference between acoustic characteristics, (b) the lax and tense Fricative Consonant's distinctive auditory cues contain a hierarchy, and (c) there is a different hierarchy between CV and VCV.

The purpose of this study was to identify whether environmental evidence and experiences respectively could affect brand attitude in Korean restaurant. Also, this study investigated a moderating effect of brand reputation in the causal relationship between environmental evidence and brand attitude and, between experiences and brand attitude. Questionnaires were given to a sample of customers who visited branches of H or B Korean restaurant brand which ranked within 20th in sales volume among Korean restaurant brands. A total of 353 questionnaires were analyzed with hierarchical regression analysis using SPSS/PC+. There were four major empirical research findings. Firstly, among components of environmental evidence, space, aesthetics, cleanliness and pleasance affected brand attitude. Secondly, all components of experiences, act, relate, think and feel affected brand attitude. Thirdly, brand reputation had a moderating role in the causal relationship between aesthetics dimension and brand attitude, but space, cleanliness, convenience and pleasance dimensions did not have a moderating role of brand reputation to the relationship of brand attitude. Fourth, brand reputation had a moderating role in the causal relationship between act and brand attitude, but relate, think and feel didn't have a moderating role of brand reputation to the relationship of brand attitude. Based on these findings, marketers of Korean restaurants were recommended to strengthen environmental evidence and experiences. Also, they are advised to strengthen brand reputation with use of marketing.

According to developments of digital signal processing, 3D sound come into focus on multimedia systems. Many studies on 3d sound have proposed lots of clues to create realistic sounds. But these clues are only focused on binaural systems which two ears are normal. If we make the 3d sound using those clues at monaural systems, the performance goes down dramatically. In order to use the clues for monaural systems, we have studies algorithms such as duplex theory. In duplex theory, the sounds that we listen are affected by human's body, pinna and shoulder. So, we can enhance sound localization performances using its characteristics. In this paper, we propose a new method to use psychoacoustic theory that creates realistic 3D audio at monaural systems. To improve 3d sound, we calculate the excitation energy rates of each symmetric HRTF and extract the weights in each bark range. Finally, they are applied to emphasize the characteristics related to each direction. Informal listening tests show that the proposed method improves sound localization performances much better than the conventional methods.

최근 음악을 재생할 수 있는 다양한 소형기기들의 발전이 이루어지고 있다. 휴대용 음향기기에서 곡을 탐색할 경우, 곡 탐색 습관의 특성상 눈으로 확인하지 않고 손을 사용한 촉각적 피드백만을 이용하는 것이 대부분이다. 또한 곡 탐색 과제는 청각적인 표적을 찾는 것임에 반하여, 지금까지 청각적인 단서에 대한 연구의 대부분은 시각적인 표적을 찾는 것에 집중되어 있었다. 본 연구에서는 청각적인 표적을 탐색하는데 있어 청각적 위치 단서가 미치는 영향을 알아보고자 하였다. 주어진 곡 리스트를 암기한 후, 화면에 제시되는 표적 곡을 탐색하는데 있어 청각적인 위치 단서가 있는 좌우 조건, 가운데 조건, 그리고 무음 조건의 경우에 따른 곡 탐색의 정확률과 반응 시간을 측정하였다. 과제는 정상과 오류 두 가지 유형으로 구성되었다. 결과는 청각적인 위치 정보가 포함된 좌우 조건이 정상 과제와 오류 과제에 있어서 가운데 조건과 무음 조건에 비하여 모두 유의미하게 짧은 반응 시간을 보였다. 본 실험 결과는 휴대용 음향기기뿐만 아니라 위성항법장치(GPS), 가상환경(Virtual Environment) 등과 같이 청각적인 표적을 찾아야 하는 과제를 포함하는 환경에도 적용될 수 있을 것이다.

This study aims to understand what aspects among perceived environmental cues affect on satisfaction and behavior intention of visitors with the object of Gwangju Chungjang Festival 2008, which is a city festival. The survey was performed in the festival period, from October 7 through, 12 2008 with 300 visitors who finished the touring of the Festival. All the 300 questionnaires were returned, but only 270 out of 300 were used, except for the unfaithful responses, for the analysis. For statistical process of the collected data, frequency analysis, reliability analysis, factor analysis and multiple regression were performed by using SPSS 12.0 for Windows via the process of data coding. As the result, first, the factor, environmental cues of city festival were shown differently in three dimensions of satisfaction. In other words, 'food factor' is an important factor for festival satisfaction. Second, for re-visit intention, which is the consequence variable and behavior intention of satisfaction regarding the environmental cue factor, 'convenient facility factor' and 'accessibility and promotion factor' were significant and 'promotion and guidance factor' for the recommendation factor was significant. On the contrary, 'food factor' did not have significant impact. Third and finally, as the analysis result of impact of festival satisfaction on re-visit intention and recommendation intention, which are the behavior intentions, festival satisfaction was significant. This study aims suggestion of development strategies for Gwangju Chungjang Festival 2008. It is appropriate time for this study at the point of promoting city festivals. Also, suggestions in this study can help promotion of development direction.

This experimental study examines whether paralinguistic behavior is a deception cue in an interrogation. 92 college students participated in an experiment and were randomly assigned to two conditions. Participant were then asked to take the money or not to take the money according to the condition they were assigned. Then participants had a face-to-face interrogation. During the interrogation, participants' paralinguistic behavior was recorded and used for coding and analysis. Results reveal that participants' paralinguistic behaviors differ depending on question types and deceptive paralinguistic cues are speech speed and fillers for the closed critical question and response latency, response length, and fillers for the open critical question. These findings implicate that part of paralinguistic behavior could be a deception cue and thus these cues might be applicable to deception detection in real world criminal investigations.

Previous research found that merely touching an object can create psychological ownership and the endowment effect. It was also found that just imagining touching an object without actually touching the object can make the same effect on psychological ownership. Prior research on haptic imagery examined the effect of haptic imagery induced by direct instruction of imaging on psychological ownership. We investigate a new method which can induce the haptic imagery in a more natural way than direct instruction of imaging. We manipulated imagery conditions such as visual-haptic congruence multimodal cue, visual-haptic incongruent multimodal cue, direct instruction condition and control condition, and examined the effects on imagery vividness, feeling of physical control, perceived ownership, and purchase intention. We conducted the experiment on 140 undergraduate students and our results showed that visual-haptic congruence multimodal cue condition is more effective than direct instruction of haptic imagery while visual-haptic incongruence multimodal cue condition is not effective. Our study extends prior haptic imagery research by making important marketing implications for online retailing.

인간에게 경험이란 삶의 흔적이며 과정이다. 어떤 경험을 했는지, 느낌을 갖게 되었는지, 본적이 있는지, 만진 적이 있는지 등 다양한 인지 요소들은 그 기억만으로 그 인간의 특성이 되고 성질이 된다. 이러한 모든 경우를 재인이라고 한다. 이러한 기억 인출 단서들이 현존감이 강한 가상환경에서 발견되느냐, 발견되지 않느냐에 따라 미디어적 환상성이 아닌 사용자에게 가상에서의 '현실'을 제공하는 중요 요소로 작용할 것이다. 또한 가상현실 콘텐츠의 이해가 미숙한 사용자라도 가상환경에서 선행경험에 대한 재인요소를 제공받을 수 있는 중요한 단서가 될 수 있다면, 콘텐츠에 대한 높은 만족감을 기대할 수 있을 것이다. 본 연구는 가상현실 콘텐츠의 만족도를 올리는 요소로서, 재인에 대하여 고찰하고 개인의 재인과 가상현실 콘텐츠 만족과의 상관관계를 연구하여 양질의 콘텐츠 서비스를 제공하는데 기여하고 가상현실을 경험하는 사용자의 심리적인 영역까지 이해의 폭을 넓히고자 함이다.
