사람은 실내나 인공구조물을 가진 실외 환경에서 깊이를 지각하는데 소실점이라는 강력한 깊이 지각 단서를 활용한다. 소실점은 관찰자로부터 가장 먼 거리의 지점에 대응된다. 인간은 단안영상이 가지는 기하학적 성분을 이용해서 소실점을 추정하고, 소실점의 위치와 관찰자의 시점을 기준으로 상대적 깊이지각을 할 수 있다. 본 논문에서는 하나의 소실점을 가진 2차원 단안영상에서 유효한 소실점을 추정하고, 입력영상에 대한 소실점의 위치 관계를 이용한 상대적 깊이지도의 생성 방법을 제안한다.

The purpose of this study was to analyze the perceptions of local residents towards the tourism impacts. The region of this study, Anmyeon-do has been developed as an international tourist destination since 1993. This study was trying to estimate the perception differences between groups of resident in teams of socio-demographics, geographic characteristics and psycho-behavioral characteristics. Self-administered questionnaire survey was administered for the residents. Frequency analysis, factor analysis, t-test, and ANOVA was tested for the perception differences. Using segmentation approaches, it was revealed that geographic characteristics and psycho-behavioral characteristics were relatively useful to test the perceptions differences of residents towards tourism impacts. Implications are drawn for regional tourism policy and management.

The purpose of this study is to investigate the predictability of variables among technology easy to use, perceived usefulness, and technostress that had impacts on kindergarten preservice teachers' technology intention to use. For this study, the survey data collected by 64 students who were enrolled in the kindergarten preservice teacher education were analysed by using multiple regression analysis. The results of this study showed as follows. First, technology easy to use significantly affected perceived usefulness. Second, technology easy to use negatively affected technostress. Third, perceived usefulness significantly affected technology intention to use while technostress negatively affected it. From this results, it is revealed that various technology training opportunities would be provided for improving preservice teachers' technology intention to use and lessing preservice teachers' technostress. Furthermore, effective teaching-learning strategies for utilizing technology as an educational media should be developed in the early childhood educational environment.

This study is focused on analysing the relationship among ethical consumption concept, fair tourism attitude and purchasing intention of ethical consumption on tourism social media with considering risk perception of ethical consumption as a mediator between fair tourism attitude and purchasing intention of ethical consumption. We found the results as follows. First, the statistically positive relationship is found between ethical consumption concept and fair tourism attitude and between fair tourism attitude and purchasing intention of ethical consumption. And also we observed that the moderating effects of risk perception of ethical consumption on the relationship between fair tourism attitude and purchasing intention of ethical consumption. The most important is resulted as offering fair tourism information through social media.

This study investigated the purchase intention of TikTok Live Commerce users by applying the Decomposed Theory of Planned Behavior(DTPB). This study conducted a survey of 512 users with experience in purchasing TikTok Live Commerce in China. Result of the analysis, first, it was found that attitudes, subjective norms, and perceived behavioral control all had effect on the purchase intention of TikTok live commerce. Second, it was found that perceived usefulness, interactivity, and perceived enjoyment had a positive effect on attitudes, but perceived ease did not have a statistically significant effect. The third,friend was found to have an effect on subjective norms. It was found that self-efficacy had a significant effect on perceived behavior control, but the facilitating condition did not significantly affect perceived behavior control.

스발바드 서측에 위치하는 스피츠버겐 하부의 암석권맨틀의 분화시기를 규명하기 위하여, 두 개의 독립적인 방사성동위원소 시스템인 Lu-Hf과 Re-Os 시스템을 스피넬 페리도타이트(spinel peridotite)에 활용하였다. 전암에 대한 Re-Os 계통(Re-Os 에러크론, 알루미노크론, Re-결핍연대 등)은 연구지역의 페리도타이트가 대류하는 맨틀로부터 고기원생대/후기시생대에 분리되었음을 지시한다. 흥미롭게도 이런 연대는 페리도타이트내 단사휘석 결정들에 대하여 얻어진 Lu-Hf 에러크론 연대와 일치한다. 또한 시료 내에 지구화학적으로 기록된 현무암질 액의 결핍정도 역시 계통적으로 위의 연대를 지지한다. 위 연대는 스피츠버겐 서측부에 보고된 가장 오래된 지각의 연대와 일치한다. 따라서 연구지역의 암석권맨틀이 연약권으로부터 분리된 것은 접촉하고 있는 지각과 동시기적으로 이루어진 사건임을 알 수 있다. 연구지역은 팔레오세 이래로 복잡한 지구조적 응력장 변화(압축에서 신장환경으로의 변화)를 겪었다. 그럼에도 불구하고 지각과 커플링된 암석권맨틀이 현존한다는 것은 연구지역내 응력장변화가 대규모의 암석권 디라미네이션(delamination)을 유발하지는 않았다는 것을 의미한다. 그러므로 북극권의 화산활동을 설명하기 위하여 북극권 상부맨틀에 존재한다고 알려진 듀팔(DUPAL) 같은 부화된 물질의 성인으로 일부의 연구자들이 주장하여 온 디라미네이션된 암석권맨틀의 존재는 설득력이 없다고 판단된다.

While the importance of adopting cloud computing service has been emerged, comparatively little research has been conducted on examining factors of an individual user's intention to switch toward cloud computing service. Hereafter, this study presents and empirically tests users' intention to switch to cloud computing. Our model posits that the characteristics of cloud computing such as effectiveness, economics, accessability, switching cost, security concern, and satisfaction toward existing IT service to cloud service affect perceived value, which in turn, influences intention to switch. An experimental study using student subjects provided empirical validation for our proposed model. Survey data from 204 respondents was used to test the model using partial least square analysis. As the result of the analysis, five hypotheses out of seven hypotheses were supported. According to our results, among the characteristics of cloud computing, effectiveness, economics, switching cost, and security concern were found to have significant impact on users' intention to switch that mediated by perceived value. Based on our research findings, we hope that this research will stimulate researchers' interest in the emerging area of cloud computing adoption.

With the advent of smart media, short and fast-paced video content appeared, and conditions for viewing changed to viewing in environments where the perception is dispersed due to distracting and complicated external situations in a short period of time. Accordingly, smart media videos are quickly delivering meaning while keeping the eyes of viewers who lack patience. Our eyes and brain have a hard time accepting image information that flows through the constraints of a small screen. Our visual perception is limited in terms of acceptable visual information and, in particular, less cognition in moving images, so the production of smart media images should be directed in a way that enhances perceptual understanding. To be able to effectively communicate what you want to talk about while reducing the visual burden, intuitive image comprehension is needed by applying intuitiveness and behavioral induction to the moving images. Close-up shot, stable structure such as frontality and three-division structure, and color have such 'visual affordance' Therefore we need to use that device appropriately.
