The purpose of this study was to evaluate the usefulness of cerebral angiography in each energy level by using dual energy technique in CT. Methods were performed on 15 DE images and SE images of CT angiography. For the analysis of images, mean value, standard deviation, SNR and CNR value were determined by setting ROI on MCA, brain parenchyma tissue, and back ground. As a result of concurrent visual evaluation with Likert 5 point scale, the clearest MCA image was confirmed at DE 40 keV and SE 120 kVp(p>0.05). The SNR value of the SE image was measured to be similar to the 40 keV energy level of the DE image. The low energy level image of 40 keV and 50 keV was measured with a high SNR and the contrast ratio was higher than that of the high energy image.

A positive destination image has an impact on the tourist arrivals and economic growth of the tourist destination. Recently, the content generated by sharing tourist experiences and destination information on the internet has been increasing. The online content has the potential to become a major tourist decision source and provide more in-depth materials and richer content to extract destination image, insight and tourist's perceptions of the destination. This study was designed to explore the destination image of Daegu online and draw lessons for successful image management in an era of big data. Text mining approach and social network analysis were conducted to extract destination image determining elements and assess the influence of the elements. The result showed that destination image elements related to tourist infra-structures and culture, history and art affected the overall destination image of Daegu. Destination marketers should make an effort to grasp these precise destination image and seek ways to boost competitiveness as a tourist destination.

The purpose of this study is to understand the social welfare approach and to suggest implications for the establishment and expansion of social welfare techniques in recent urban regeneration to overcome the limitation of physical approach to urban regeneration. We used the method of the content analysis to extract social welfare programs in project plans of urban regeneration regions and vulnerable residence regions and then let them be categorized according to characteristic and form of their programs. As a result of the analysis, there are 4 welfare programs in urban regeneration regions; setting the economic fundament, improving the residential environment focusing on welfare, pursuing community integration and social service providing. And each type was classified into 12 subtypes. Based on the result of this study, some implications are suggested to operate social welfare techniques in a stable manner in urban regeneration projects; link of the suitable jobs for regional characteristics, the participation of local residents in the project process, empowerment for community integration and expanded provision of social services.

This study, the Fear of Missing Out Scale (FoMO Scale) developed by Przybylski et al. (2013) was adapted and validated to the Korean culture. 3-factors were constructed through EFA and item content analysis. In the CFA, 3 models were constructed to verify the fit of the model. Compared the goodness of fit, 3-factors model with 8 items proved to be the most appropriate. Sub-factors extracted through the characteristic context and rationale of Korean culture are 'belonging needs', 'extrinsic motivation', and 'relative deprivation'. K-FoMO scale and the reliability level of each sub-factor were good. Convergent validity was assessed by significant correlation the K-FoMO scores with life satisfaction, positive emotions, negative emotions, and SNS addiction proneness. Discriminant validity was assessed by low correlation with gratitude. At the end, limitation and suggestions for the future research were discussed.

The purpose of this study is to present the mental model of young adolescents' media environment and the use and to provide several educational suggestions drawing on the revealed model. For this, the data were collected through 4 activities such as interview, picture drawings, word association experiment, and sentence completion task with ten 4-5th graders in elementary schools; they were qualitatively analyzed by 2 researchers. First, the meaning components driven by sentence completion task, word association experiment were totally 6 components: media device, connection(alienation), competence(provision), entertainment, adverse effects, ambilaterality. Second, the components of media mental model driven by pictures were 4 components: functions/competence, entertainment, conflict with paper books/sharing, harmfulness/ambilaterality. Third, the components from interview consisted of conflict between paper books and electronic media, communication-centeredness, fear(addiction) and users' qualification. Based on those results, careful examination in cyber talk, necessity of addiction prevention, active development of learning media and their balanced utilization with books, and healthful media literacy education and reinforcement of critical thinking were suggested.

To generate a complete 3D model from depth images of multiple RGB-D cameras, it is necessary to find 3D transformations between RGB-D cameras. This paper proposes a convenient view calibration technique using a spherical object. Conventional view calibration methods use either planar checkerboards or 3D objects with coded-pattern. In these conventional methods, detection and matching of pattern features and codes takes a significant time. In this paper, we propose a convenient view calibration method using both 3D depth and 2D texture images of a spherical object simultaneously. First, while moving the spherical object freely in the modeling space, depth and texture images of the object are acquired from all RGB-D camera simultaneously. Then, the external parameters of each RGB-D camera is calibrated so that the coordinates of the sphere center coincide in the world coordinate system.

The theme is the core of the work in all media including the games. In order to develop successful games, it must effectively express the game theme. In order to express the game theme, it must be able to understand and to utilize the characteristics of the game theme. This Study extracted 11 characteristics of the game theme through the precedent literature research and found 4 core characteristics of the game theme through interviews with 11 experts. This Study conducted a survey about 4 core characteristics of the game theme in Final Fantasy X of Japan and Skyrim of USA. As a result, degree of an expression about 4 core characteristics of the game theme received high-rated in common(3.45~4.59 / 5). It may become guidelines for the theme studies in the other games. I will contribute to develop successful games through understanding and utilizing the 4 core characteristics of the game theme.

This paper proposes an ATR (Automatic Target Recognition) algorithm for identifying non-occluded and occluded military vehicles in natural FLIR (Forward Looking InfraRed) images. After segmenting a target, a radial function is defined from the target boundary to extract global shape features. Also, to extract local shape features of upper region of a target, a distance function is defined from boundary points and a line between two extreme points. From two functions and target contour, four global and four local shape features are proposed. They are much more invariant to translation, rotation and scale transform than traditional feature sets. In the experiments, we show that the proposed feature set is superior to the traditional feature sets with respect to the similarity-transform invariance and recognition performance.
