The volume rendering has become an important technique in many applications along with hardware development. Understanding and perception of volume visualization benefit from visual cues which are available from shading. Better visual cues can be obtained from global illumination models but it's huge amount of computation and extra GPU memory need cause a lack of interactivity. In this paper, in order to improve visual cues on volume rendering, we propose an image space occlusion shading model which requires no additional resources.

This paper deals with a comparative analysis of changes in cognition of city image of Daegu City, focusing on image of representative and environmental conditions. Two-questionnaire surveys were conducted to compare the change of image cognition between the last decades. Major results are: Firstly, the most frequent representative images of Daegu City were hot weather, Palgong Mountain, textile industry, etc. and representative places were Palgong Mountain, Dongsung-ro Street, E world(Woobang Land), etc. Compared to the results of year 2000, the frequency of apple, and textile industry were remarkably decreased. Secondly, mean scores of image rating for environmental conditions were comparatively high in human environment such as women, and kindness. By individual variables, accessibility to Daegu City, women, living environment such as shopping, showed higher mean scores. Generally, mean scores of 2011 survey were higher than that of 2000. Thirdly, major factors affecting city image were human environment, living environment, natural environment, and transportation environment, respectively. These results can be used as a basic data for strategies to improve higher brand image of Daegu City.

The study was performed to measure structural relationship among service value, brand image, and royalty of patients in regional public hospitals in Korea. Based on the analysis, the study aims to establish strategic direction of the regional public hospitals. Through a review of related literatures, measurement variables were identified, and a path model was developed for the study. Five regional public hospitals were chosen, and questionnaire has been collected from 387 outpatients and 358 inpatients. The study found that service value has a positive direct effect on brand image, and brand image has a positive direct effect on loyalty. Based on the findings, it is desirable for the regional public hospitals should mange the issues with lower level of perception and those with bigger effect, and establish low pricing strategy with improving the quality of service they provide.

With the advance of digital technology, new methods which acquire color information and combine it with various contents are emerging. Color has some effect on emotion while it gives some information as component of an image. In addition, change in emotion and sensation from color stimulus makes some change in cognition. This research investigate the effect of color overlay on cognition depending on emotional state. With this goal, subjects consisting of 10 men and 10 women solved some problems with color overlay of red, orange, and green after watching short video clips which intend to induce target emotion. Experimental results show that red color overlay under positive emotion significantly reduces the average score of solving problems, while green overlay under negative emotion significantly increases it. It is also analyzed that there is not statistically significant difference in cognitive function with color overlay while it is significantly better under positive emotion than negative emotion without color overlay.

In this paper, a CMOS digital image sensor, which consists of A/D conversion, motion estimation circuits, and an attention module for ROI (Region of Interest) detection is presented. The functions of A/D conversion and motion estimation are implemented by $0.6{\mu}m$ CMOS processing circuit as hardware, and the attention module is implemented outside the circuit as software currently. Attention modules are taken to improve limited applications of the smart image sensor. The current smart image sensor responses to the changes of intensity, and uses the integration time to estimate motion. Therefore it is limited in its applications. To make up for inherent property of the sensor from circuit design and extend its applications we decide to introduce perception solutions to the image sensor. Attention modules for still and moving images are employed to achieve such purposes. The suggested approach makes the smart image sensor available with additional functions for such cases that motion estimation or intensity changes are not observed. Experimental result shows the usefulness and extension of the image sensor.

Though the education of culture and art for disabled children is very important, it has not been brisk yet until recently due to 'absence of the teaching methods suitable for disability types, levels and programs.'. In this situation, cartoon contents can be used as the most appropriate tools for culture and art education for mentally retarded children. Entertainment functions and genre features of cartoon contents can motivate the applicable children to participate more voluntarily and positively and function as teaching tools for interesting activities. Of course, since it is not proper to apply the cartoon contents for normal children to Special Education Field as they are, cartoon works should be made by understanding closely the characteristics and degrees of retardation of the applicable children and applying them to the composition of cartoons. However, for the contribution of this attempt to education field, it is thought that concrete guidelines for producing cartoon contents considering the concept of various types of disability, emotion, social behavioral traits, ability of cognition, school achievements, and the characteristics of language and physical health should be necessary, and to improve the application of the developed cartoon contents so that they will not remain as superficial results, sufficient communication with the applicable children such as application to classes in the process of development is necessary.

As online video advertising market grows, viral advertising is drawing attention. This study investigated factors influencing consumer's sharing intent of viral advertising each from four dimensions which are content, sender, consumer, and network. As a result, factors of persuasive intent, brand-ad image fit, perceived self-presentation, and bridging social capital were found to affect consumer's sharing intent of viral advertising. And persuasive intent of content was found to be negatively affect consumer's sharing intent. Social value and bonding social capital were not found to have significant influence on consumer's sharing intent of viral advertising. From the analysis of this result, this study suggested future research topic and academic/practical implications.

과거부터 사람들은 달을 인지해왔으며, 인류는 지속적으로 달을 관찰하고 탐구를 멈추지 않았다. 지역문화와 민족문화가 다르기 때문에 달의 이미지에 관한 다른 이해를 바탕으로 미술, 건축, 종교 등에 반영되어 왔다. 영화기술의 발전과 더불어 다양한 영상콘텐츠에도 달이 등장해왔다. 하지만 달에 대한 상징성 연구가 미흡하여 영상콘텐츠에서의 달 이미지 활용에 어려움이 있어왔다. 때문에 본 연구를 통해 영상콘텐츠에서 표현된 달 이미지를 연구하여 달의 의미를 분석하고 표현 방법에 대한 전문성을 높이고자 한다. 연구방법은 첫째, 지역 및 문화별 달의 의미를 제시한다. 둘째, 달과 여성의 이미지 사이의 관계를 이론적 배경으로 제시한다. 셋째, 달의 여성상징적 의미에 관한 영상콘텐츠 작품 사례를 분석하였다. 연구결과 동서양 신화에 등장하는 달의 여성상징은 영상콘텐츠에서 등장인물의 이름과 디자인의 활용 등이 주를 이루었다. 본 연구를 통해 달에 대한 상징에 대한 동서양의 특징을 도출하고, 향후 영상콘텐츠 작품 창작에 활용되기를 기대한다.

정보처리 기술이 발전함에 따라 정보에 대한 접근과 소통은 더욱 빠르고 편리하게 되었고, 동시에 사용자의 정보에 대한 요구 또한 세분화되고 다양해지면서, 이러한 다양한 요구에 대응하기 위해서 사용자의 경험과 소통하여 인지과정에 영향을 줄 수 있는 감성이 중요하게 인식되고 있다. 감성은 동일한 외부자극에 대해 개인의 경험, 환경 등에 따라 다르게 나타나기 때문에 객관적으로 측정하기가 어렵지만, 외부자극에 대해 반사적이고 직관적으로 발생하여 의사결정 과정에 지속적으로 영향을 주기 때문에 사용자의 경험과 소통하여 사용자의 요구를 이해할 수 있는 정보를 제공한다. 본 논문에서는 이미지 공유 사이트를 이용하여 이미지라는 외부자극에 대해 사용자들이 느낀 어휘들을 수집하고 긍정과 부정 감성을 분석하여 어휘를 기반으로 이미지의 감성을 측정하고 평가하였다.
