Discussions and debates over media education abound in Korra as the number of both institutions that provide media related education and students enrollment for these programs increases rapidly in recent years. In spite of this rather impressive expansion, however, many have raised serious questions about media education of Korea for its not being able to meet the need of the Industry and students, and, moreover, inability to face the challenges brought by new communication related technologies. Who teaches What for what purposes are some of the fundamental questions underlying these heated debates and discussions. To understand these rather complex and interrelated issues more clearly, it is attempted to delineate the nature of these debates by exploring the evolutionary process of media education. The issues related to debates over purposes of media education, curriculum, and faculty qualification have changed through the history of media education, but the nature of the debates, that is the struggle between professionalism and academism, or the tension between practice and theory, has not. Upon this understanding, some argue that what distinguishes opposing sets of dichotomies, such as skills vs. knowledge, training vs. education, now-how vs. know-why. professional vs. academic, practice vs. theory, is more a reflection of social class division and group interests which have privileged theory over practice than a rational scholastic distinction. In addition, it has been often pointed out that the media studies have failed to establish ties with specific industries, and furthermore academic studies seriously lack solid theoretical and practical bases. In the case of the United States, leaders of the industry had contributed much for the Initiation of journalism education in a college setting. However, once inaugurated,, the process of its evolution has depended heavily on academicians. In a country like Korea, where academic and theoretical orientation is much stronger, these problems of media studies and education are even more acute. In this study, it is suggested that academicians and educators be more open-hearted to the realities of changing world, practices of the industries, and recruitment of professionals and practitioners to fill the gap between practice and theory, for the sake of the future of media studies and education.

Object-based classification methods provide a valid alternative to traditional pixel-based methods. This study reports the results of an object-based classification to examine land cover in the demilitarized zones(DMZs) of Inje-gun. We used land cover classes(7 classes for main category and 13 classes for sub-category) selected from the criteria by Korea Ministry of Environment. The average and standard deviation of the spectrum values, and homogeneity of GLCM were chosen to map land cover types in an hierarchical approach using the nearest neighborhood method. We then identified the distributional characteristics of land cover by considering 3 topographic characteristics (altitude, slope gradient, distance from the Southern Limited Line(SLL)) within the DMZs. The results showed that scale 72, shape 0.2, color 0.8, compactness 0.5 and smoothness 0.5 were the optimum weight values while scale, shape and color were most influenced parameters in image segmentation. The forests (92%) were main land cover type in the DMZs; the grassland(5%), the urban area (2%) and the forests (broadleaf forest: 44%, mixed forest: 42%, coniferous forest: 6%) also occupied mostly in land cover classes for sub-category. The results also showed that facilities and roads had higher density within 2 km from the SLL, while paddy, field and bare land were distributed largely outside 6 km from the SLL. In addition, there was apparent distinction in land cover by topographic characteristics. The forest had higher density at above altitude 600m and above slope gradient $30^{\circ}$ while agriculture, bare land and grass land were distributed mainly at below altitude 600m and below slope gradient $30^{\circ}$.
A shooting game is all game genres that hit targets through shooting. It include a lot of genres from a flying shot of game room to a personal shooting action game. In this point, a shooting game was regarded it as the origin of all game and it was developed from the early days of game. At present we can meet it in an electronic game room or personal computer, and mobile phone etc.. The popularity of shooting game caused to take aim by simple system, interface, and speedy play. Also it was enticed everyone to enjoy it easily. A shooting games is worked from old like ways until recently and a process of playing game is intuitive than another game. Therefore it popular with a PC player as well as persons of all levels. Beginners can train this game easily through direction such as control way of object, advent way of enemy aircraft and scroll way of background. But as an usability of working and controlling game, beginners of game development can pass over a shooting sense that shout and hit basically. And after design, they will feel that cannot convey realistic effect and thrill etc.. At a result, hitting sense happens to graphic elements and sound. Therefore a measure of effect on these elements is started from analysis of good shooting game. This study was to focus on the advance effect of hitting sense in shooting game through analysis centered for 'the Beetlewing' and '1945 Plus'.

In a view of rapidly changing business environment, the success and competing power of organizations depend on committed, highly motivated and satisfied human resources. Empowerment is mainly concerned with establishing and building trust between management and employees, and motivating their participation. Also, behavioral integrity emphasizing on the characteristics of effective leaders has shown as direct action that strengthens positive consequences in organizations. However, research regarding behavioral integrity is very limited. Based on the Self-determination Theory, this paper investigates the effect of empowering leadership on employee's job satisfaction and work engagement. Multi-group analysis based on behavioral integrity is also analyzed. An online survey was conducted and 298 employees' data were collected. Using structural equation modeling, results suggest as follows. First, empowering leadership had a positive effect on individual's job satisfaction mediated by their work engagement. Second, the result of the multi-group analysis showed that the effect of empowering leadership on work engagement is stronger in the group with high behavioral integrity. Contrary to the prediction, the result doesn't support the moderating effect on job satisfaction. These findings contribute to our understanding of empowering leadership process. Based on the results, several theoretical and managerial implications are discussed.
This research has developed the criteria and index for systematically and objectively assessing the quality of river water by fixing the various factors that affect Gyeongin ARA waterway's water quality through analysis with the Delphi Technique and analytic hierarchy program (AHP) Method. Based on the results, the highest criteria are, in order of importance, physical and environmental factors 28%, administrative factors 26%, natural fixed factors 26% and finally, cultural and social factors 20%. The three dimensions of the criteria show that for the internal physical and environmental factors, the most important are the loss of self-purification capacity, and the external factors are Gulpocheon and the sludge deposit due to Gyulhweon-weir the bridge. The facility factor in management was affected by the coagulation and waste water disposal facilities. The problem for the policy and institutional factors was seen in the regulatory area. The aquatic ecology/ point pollution source for the natural fixed factors show that it is due to the polluted water of Gulpo-cheon and the living environment/ non-point pollution source is shown through the inflow water from other rivers. Cultural and social factors show that the economical causes were due to the cargo and passenger flight operations and the external factors of having a lack of sewage treatment equipment have an importance effect. In order to estimate the order of priority through logical evidence and objectivity, future research must be continued on the evaluation indexes to measure the specific methodology and technique needed to improve the Gyeongin ARA Waterway.

Recently, the mobility of users and mobile communication technologies have developed rapidly. The users in this state also want to connect their devices and to receive services anywhere, anytime. Hierarchical Mobile IPv6 (HMIPv6) has been proposed by the Internet Engineering Task Force (IETF) to compensate for such problems as handover latency and signaling overhead when employing Mobile IPv6 (MIPv6). HMIPv6 supports micro-mobility within a domain and introduces a new entity, namely Mobility Anchor Point (MAP) as a local home agent. However, HMIPv6 has been found to cause longer handover latency when the inter-domain handover occurs. This is because a Mobile Node (MN) has to generate two addresses and register them to Home Agent (HA) a MAP, respectively. In order to solve such problems, we propose a scheme that an MN generates one address and registers it to HA for supporting fast handover during the inter-domain handover process. In the proposed scheme, the load of MAP and MAP domain is reduced because the number of MNs which are managed by MAP is decreased and the MAP does not perform proxy Neighbor Discovery Protocol (NDP) to intercept packets destined to MNs. We evaluate the performance of proposed scheme in comparison to HMIPv6 through the simulation and numerical analysis.

The numerous improved schemes of remote user authentication based on password have been proposed in order to overcome the security weakness in user authentication process. Recently, some of biometric-based user authentication schemes to use personal biometric information have been introduced and they have shown the relatively higher security and the enhanced convenience as compared to traditional password-based schemes. These days wireless sensor network is a fundamental technology in face of the ubiquitous era. The wireless sensor networks to collect and process the data from sensor nodes in increasing high-tech applications require important security issues to prevent the data access from the unauthorized person. Accordingly, the research to apply to the user authentication to the wireless sensor networks has been under the progress. In 2010, Yuan et al. proposed a biometric-based user authentication scheme to be applicable for wireless sensor networks. Yuan et al. claimed that their scheme is effectively secure against the various security flaws including the stolen verifier attack. In this paper, author will prove that Yuan et al.'s scheme is still vulnerable to the password guessing attack, user impersonation attack and the replay attack, by analyzing their security weakness.
Purpose: The aim of this study was to explore the relationship of being from low-income families on children's behavior problems and obesity. Methods: The research design was a descriptive survey study, and the participants were 197 children from low-income families who took part in activities at a local children's center. They were selected through convenience sampling. The participants completed a questionnaire, BASC-2 (Behavior Assessment System for Children). Results: The results are as follows: 22.3% had obesity, a rate higher than that of children in general. Further, 37.3% had attention deficit problems, 33.8% had problems adapting to school and 49% had other adaption problem. There was a gender-specific difference with respect to all of the behavior problems. Conclusion: The results of this study indicate a lack of an identified child policy for behavior problems and health, and suggest a need for various programs and policies which could lead to development of behavior screening programs for children from low-income families.
This study tried to anticipate the near future changes of domestic online video, music service and media usage through the status quo. The research group was focused on the twenties, University students because they are the active media contents users. It surveyed the students in Busan, and used the method of descriptive statistics analysis for the understanding of the present state and near future prospect. This study shows that almost half of them use both services, and three people out of ten are the heavy users who use the services for over 3 hours a week. The streaming method is higher proportion than download method in using type. They are getting accustomed to pay contents cost, but it couldn't be said the paying content cost has been established. Preferred contents genre appears to be the RMC(Ready Made Contents) such as existing broadcaster contents and movies. Notable result on media usage was the proportion of the so-called 'Zero-TV'. It was 32%, significantly higher than the proportion of the total population(4.4%). Integrating the analysis results, we can expect that the usage pattern will be changed gradually, thus the advent of various revenue models will emerge.
