  • Relating to grasping sequential landscape characteristics in consideration of the behavioral characteristics of the subject experiencing visual perception, this study was made on the subject of main walking line section for visitors of three treasures of Buddhist temples. Especially, as a method of obtaining data for grasping sequential visual perception landscape, the researcher employed [momentum sequential viewpoint setup] according to [the interval of pointers arbitrarily] and fisheye-lens-camera photography using the obtained omni-directional angle visual perception information. As a result, in terms of viewpoint selection, factors like approach road form, change in circulation axis, change in the ground surface level, appearance of objects, etc. were verified to make effect, and among these, approach road form and circulation axis change turned out to be the greatest influences. In addition, as a result of reviewing the effectiveness via the subjects, for the sake of qualitative evaluation of landscape components using the VR picture image obtained in the process of acquiring omni-directional angle visual perception information, a positive result over certain values was earned in terms of panoramic vision, scene reproduction, three-dimensional perspective, etc. This convinces us of the possibility to activate the qualitative evaluation of omni-directional angle picture information and the study of landscape through it henceforth.

  • Environment perception and three-dimensional (3D) reconstruction tasks are used to provide unmanned ground vehicle (UGV) with driving awareness interfaces. The speed of obstacle segmentation and surrounding terrain reconstruction crucially influences decision making in UGVs. To increase the processing speed of environment information analysis, we develop a CPU-GPU hybrid system of automatic environment perception and 3D terrain reconstruction based on the integration of multiple sensors. The system consists of three functional modules, namely, multi-sensor data collection and pre-processing, environment perception, and 3D reconstruction. To integrate individual datasets collected from different sensors, the pre-processing function registers the sensed LiDAR (light detection and ranging) point clouds, video sequences, and motion information into a global terrain model after filtering redundant and noise data according to the redundancy removal principle. In the environment perception module, the registered discrete points are clustered into ground surface and individual objects by using a ground segmentation method and a connected component labeling algorithm. The estimated ground surface and non-ground objects indicate the terrain to be traversed and obstacles in the environment, thus creating driving awareness. The 3D reconstruction module calibrates the projection matrix between the mounted LiDAR and cameras to map the local point clouds onto the captured video images. Texture meshes and color particle models are used to reconstruct the ground surface and objects of the 3D terrain model, respectively. To accelerate the proposed system, we apply the GPU parallel computation method to implement the applied computer graphics and image processing algorithms in parallel.

  • 본 연구의 목적은 중소공급업체의 공정성 지각의 선행요인과 결과요인의 규명을 통하여 대기업과 중소기업간의 상생을 위한 요인을 파악하고자 하였다. 중소공급업체 공정성 지각의 선행요인으로는 수직적 조정, 협력지원, 정보공유, 법계약적지배의 네가지 변수를, 결과요인으로는 공급체인의존성과 공급체인유연성으로 가정하여 분석을 시도하였다. 첫째, 대형구매업체의 수직적 조정은 중소공급업체의 분배공정성 지각과 절차공정성 지각에 정(正)의 영향을 미치는 것으로 나타났다. 둘째, 대형구매업체의 협력지원은 중소공급업체의 분배공정성 지각과 절차공정성 지각에 영향을 미치지 않는 것으로 나타났다. 이는 대형구매업체가 중소공급업체에 더 큰 요구를 하는 경우가 많기 때문에 이런 결과가 나온 것으로 추정된다. 셋째, 대형구매업체의 정보공유는 중소공급업체의 분배공정성 지각에는 정(正)의 영향을 미치고 절차공정성 지각에는 직접영향은 주지 않는 것으로 나타났다. 넷째, 대형구매업체의 법계약적지배는 중소공급업체의 분배공정성 지각에 부(負)의 영향을 미치는 것으로 나타나고, 절차공정성 지각에 부(負)의 영향의 방향성은 나타났다. 다섯째, 절차공정성은 공급체인의존성에 직접영향을 미치지 못하는 것으로 나타났지만 공정성은 공급체인 의존성 및 공급체인 유연성에 직접, 간접적으로 영향을 미치는 것으로 나타났다.

  • With the popularity of mobile Internet and smart phones, the domestic digital music access platform has entered a period of rapid development. Existing studies in the academic circle have shown that experience has a positive impact on user perception and loyalty. However, the research on the relationship between brand loyalty, user perception and user experience of Internet products has not received much attention. Starting from the brand loyalty theory and user experience theory, this paper explores the mechanism of user experience, user perception and brand loyalty of digital music access platform. Based on the development status of digital music access platform in China, the purpose is to explore how the user experience of the mainstream digital music access platform can affect Usefulness Perception, Epidemic Perception. And to explore how the Usefulness Perception, Epidemic Perception can affect users' brand loyalty. also further explore the role of users' perception in this process to understand the relationship between brand and user experience. In practical operations, 398 formal questionnaires were issued online to collect first-hand data, and reliability analysis, factor analysis, correlation analysis and hypothesis analysis were carried out successively on the data in the later stage. Through research, it is found that the user experience of digital music access platform has a partial significant impact on the perception and loyalty of applications. The visual presentation and emotional feelings of digital music access platform are positively correlated with the perceived usefulness of applications. The visual presentation and emotional feelings of digital music access platform are positively correlated with the perceived popularity of applications. The e perceived usefulness and perceived popularity of the digital music access platform are positively correlated with the loyalty of the application. Through this research, it has certain guiding significance to the promotion of digital music access platform's brand loyalty degree.

  • This study analyzed purchase behavior according to the risk perceptions when customers buy Cosmetics at Internet Shopping Malls. Participants were 232 women in their 20s and 30s with more than one buying experience at an internet fashion shopping mall. Data were analyzed using factor analysis, Cronbach's analysis, cluster analysis, one-way ANOVA and a Duncan test. Results were as follows. Firstly, five factors of risk perception were identified: These were the payment risk, service risk, quality risk, price risk and experience risk. Secondly, customers of internet shopping malls could be categorized into three groups: A low risk perception group, a payment risk perception group and a high risk perception group. Factor analysis showed significant differences between these groups( p<.001). Thirdly, purchase behavior based on the purchase standards, purchase items, information searching were investigated according to the different groups of risk perception of internet shopping malls and results again significant differences between groups (p<.05, p<.001).

  • Purpose: The aim of this study was to identify the age-related differences in risk perception of breast cancer and the age-related differences in predictors of risk perception. Method: The subjects were 553 women aged from 15 to 64 who lived in Seoul, Kwang-Ju, Jeon-nam province. Data was collected by self-reported questionnaire surveys using convenience sampling. The collected data was analyzed using descriptive statistics, F-test with Scheffe test, and stepwise multiple regression with SPSS-Win 10.0 version. Result: Risk perception of breast cancer was different by age group. Especially, risk perception in teenagers and the 50~64 years group was lower than the other groups. Additionally, general fear of breast cancer, information seeking style, experience, and knowledge were different between the age groups. The results of multiple regression analyses predicting risk perception indicated the following significant predictors: general fear and knowledge in all the subjects, general fear and experience in the 20~29 years group, and general fear in the other age groups. Conclusion: These results suggested that the construction of educational messages for breast cancer prevention and early detection should be designed differently for each age group.
