Screen Quota is very important topic at our whole society not only film industry. Moreover the opinions are sharply divided. So, journalism, at the objective and neutral position, has the responsibility to present objective field to discuss and neutral information. This script censoriously focuses that how Korean Journalism handles Screen Quota issue from the upper mentioned premises. The first point is Korean Journalism gives legitimacy to the Governmental persistence, which is fixing Screen Quota as a hurdle for the FTA settlement so that it should be reduced. Secondly, Korean Journalism has been reducing the importance of the Screen Quota issue as the problem of film industry itself own, describing it as combat between Government and Film Industry. Third, it describes the Screen Quota as a privilege granted to the Film industry only. Finally, it provides power to the point of view of the Government which insists to reduce the Screen Quota mentioning the superiority of the competitiveness of the Koran Films discriminatingly. In conclusion, I could not but define that Korean Journalism is only speaking for America and Korean Government especially about the Screen Quota issue which is divided sharply. What it means is Korean Journalism has not been providing not only objective information but also impartial dispute field to the public for the issue which has very importance socially. The news and discussions about Screen Quota shows that this issue is not free from the progress of FTA which includes the Screen Quota problem. Further on, it could be deduced that the discussion about Korean film industry has kept on focusing its topic to the choice of decreasing or maintaining Screen Quota. The cultural contents have been expanding its importance day by day. Endeavors to settle the enormous problems of film industry should be preceded to strengthen the competitiveness and to prepare against market opening. Consequently, to solve the problems of film industry, Screen Quota should be positioned as a protect policy rather than a remedy for every ill, at the same time all the possibilities should be considered especially for the problems that Screen Quota could not solve.

Gotjawal areas have the unique ecosystem and we need to approach as the inhabit of animals to conserve Gotjawal. This study was conducted in Hangyeong-myeon Cheongsu-ri located in the western part of Jeju Island belonging to Hangyeong Andeok Gotjawal Zone and Jocheon-eup Seonheul-ri located in the eastern part of Jeju Island belonging to Jocheon Hamdeok Gotjawal Zone. Survey on advent of the birds was done twice a month from February 2013 to December 2014. A total of 66 species and 4,140 individuals in two Gotjawals were observed during the survey period. In Seonheul Gotjawal area, 53 species and 1,907 individuals were observed while it was 49 species and 2,233 individuals in Cheongsu Gotjawal area. The number of species between two Gotjawal areas was not significantly different, but the number of individuals between two Gotjawal areas was significantly different. Thirty-six species were found in both Gotjawal areas as common species and the index of similarity was 0.7. A total of 23 species were classified as the residents, 15 species as the winter visitors, 16 species as the passage migrants, 11 species as the summer visitors, and 2 species as the vagrant. Twelve species as legally protected birds including the natural monument and the endangered species were found and 8 species were found in Seonheul Gotjawal area while it was 10 species in Cheongsu Gotjawal area. The species that directly using a wetland or food resources related to water were 12 in the Seonheul and 6 species were observed in the Cheongsu Gotjawal area, but there is no significant difference between two Gotjawal areas. However, the number of individuals in Seonheul Gotjawal area was significantly higher than in that of in Cheongsu Gotjawal area. We need to research the wetlands and micro climatic condition existing in Gotjawal forests to find the cause of difference of two areas and this difference must be considered as an important indicator for the protection of Gotjawal forests.

The objective of this study is to uncover the standard and procedure of the review for the online game to export to China and try to find a plan how to solve a problem such as regulation for the online game imported into China depending on a protective policy for homemade game. The literatures related to the policy of China online game industry and the present condition of the wholistic restriction are reviewed and the standard and procedure of the review of China online game which is veiled was able to find definitely by using the case study on Korean company which was a great success as localization in China. As a result of this study, we found that the key factor on the review standard of China online game is the anti-social personality, such as 'the overthrow of Chinese socialist system', 'the territorial issue as the eviction of Hong Kong or the acknowledgment of Taiwan government', 'independence problem of the minorities', and 'damage to property as national treasure', et cetera. While the review of the homemade game in China takes about a month through just two steps in review process on online game, that of foreign game is required over at least three months through four steps in it. Moreover, it is difficult for foreign games to obtain the license due to total amount regulation for online game by 'General Administration of Press and Publication of the People's the Republic of China'. In the case of the joint-venture company, it is most important to the smooth communication between Korean company and Chinese company in order to overcome these strong regulation for online game review in China. Furthermore, as Chinese company in outward appearance it is need to be positioned absolutely in Chinese marketplace. The definite positioning strategy enables foreign companies to avoid the strong regulation about the foreign game in China. To understand, finally, deeply politics, society, and culture presented in Chinese ethics textbook permits the foreign companies to predict the exact standard of the review for online game. Therefore, this study is concluded with key implications to sustain guidelines on the deliberation for foreign companies which want to export online game to China to improve the predictability and accountableness about the review of the online game in China.

The rise of income and introduction of 5 day a week working system give korean people opportunities to enjoy their leisure time. And many korean people have much interest in oceanic sports such as yachting and also oceanic leisure equipments. With the popularization and development of the equipments, the scope of oceanic activities has been expanding in Korea just as in the advanced oceanic countries. However, The current conditions for the sports in Korea are not advanced and even worse than underdeveloped countries. In order to develop the underdeveloped resources of Korean marina, we need to customize the marina models of advanced nations to serve the specific needs and circumstances of Korea As such we have carried out a comparative analysis of how Austrailia, Newzealand, Singapore, japan and Malaysia operate their marina, reaching the following conclusions. Firstly, in marina operations, in order to protect personal property rights and to preserve the environment, we must operate membership and non-membership, profit and non-profit schemes separately, yet without regulating the dress code entering or leaving the club house. Secondly, in order to accumulate greater value added, new sporting events should be hosted each year. There is also the need for an active use of volunteers, the generation of greater interest in yacht tourism, and the simplification of CIQ procedures for foreign yachts as well as the provision of language services. Thirdly, a permanent yacht school should be established, and classes should be taught by qualified instructors. Beginners, intermediary, and advanced learner classes should be managed separately with special emphasis on the dinghy yacht program for children. Fourthly, arrival and departure at the moorings must be regulated autonomically, and there must be systematic measures for the marina to be able, in part, to compensate for loss and damages to equipment, security and surveillance after usage fees have been paid for. Fifthly, marine safety personnel must be formed in accordance with Korea's current circumstances from civilian organizations in order to be used actively in benchmarking, rescue operations, and oceanic searches at times of disaster at sea.

A total of 24 families, 44 species, and 658 benthic macroinvertebrates were identified, and Ecdyonurus dracon Kluge (13%) was the dominant species in forested streams within the Yeonyeopsan (Mt.). A total of four habit categories (i.e., clingers (56%), burrowers (19%), swimmers (14%), and sprawlers (56%)) were identified, and clingers were the dominant habit at all survey points except point one (UP1). Habitat characteristics were depended on the hydraulic factors (e.g., flow velocity, depth, and substrates), water quality (e.g., DO and water temperature), and the habitat characteristics were differed in the riffle, which has a faster the flow velocity, compared by in the stagnant pool. In other words, in riffles, the clingers dominated in high flow velocity with the large maximum and median grain size for substrates in the habitats regardless of depth, but the burrowers and sprawlers were dominant in low flow velocity with the small maximum and median grain size for substrates in the habitats. Moreover, DO and flow velocity were in positive correlation (y = 0.6666x - 0.659, R² = 0.0851), and the habitat for burrowers was wider than that for sprawlers or clingers. The water depth was negatively correlated with water temperature (y = -26.397x + 283.87, R² = 0.1802) since the water temperature is more sensitive to insolation in shallow depth. pH was positively correlated with water temperature. The investigation of the habitat characteristics by separating the relations between pH and DO in upstream and downstream showed the low pH and high DO in the upstream with a high crown density of 68%, regardless of community composition. On the other hand, high pH and low DO in the downstream with a relatively low crown density of 51%. It was considered that the riparian forest played a role in suppressing the growth of attached algae and the controlling water temperature in headwater streams. Our findings identified the habitat characteristics of benthic macroinvertebrates in a headwater stream. We expected that the finding can provide reference data for suggesting conservation and management plans in a headwater stream and increasing academic value.

Widespread popularity of wireless data communication devices, coupled with the availability of higher bandwidths, has led to an increased user demand for content-rich media such as images and videos. Since such content often tends to be private, sensitive, or paid for, there exists a requirement for securing such communication. However, solutions that rely only on traditional compute-intensive security mechanisms are unsuitable for resource-constrained wireless and embedded devices. In this paper, we propose a selective partial image encryption scheme for image data hiding , which enables highly efficient secure communication of image data to and from resource constrained wireless devices. The encryption scheme is invoked during the image compression process, with the encryption being performed between the quantizer and the entropy coder stages. Three data selection schemes are proposed： subband selection, data bit selection and random selection. We show that these schemes make secure communication of images feasible for constrained embed-ded devices. In addition we demonstrate how these schemes can be dynamically configured to trade-off the amount of ded devices. In addition we demonstrate how these schemes can be dynamically configured to trade-off the amount of data hiding achieved with the computation requirements imposed on the wireless devices. Experiments conducted on over 500 test images reveal that, by using our techniques, the fraction of data to be encrypted with our scheme varies between 0.0244％ and 0.39％ of the original image size. The peak signal to noise ratios (PSNR) of the encrypted image were observed to vary between about 9.5㏈ to 7.5㏈. In addition, visual test indicate that our schemes are capable of providing a high degree of data hiding with much lower computational costs.

Studies on target motion in 4-dimensional radiotherapy are being world-widely conducted to enhance treatment record and protection of normal organs. Prediction of tumor motion might be very useful and/or essential for especially free-breathing system during radiation delivery such as respiratory gating system and tumor tracking system. Neural network is powerful to express a time series with nonlinearity because its prediction algorithm is not governed by statistic formula but finds a rule of data expression. This study intended to assess applicability of neural network method to predict tumor motion in 4-dimensional radiotherapy. Scaled Conjugate Gradient algorithm was employed as a learning algorithm. Considering reparation data for 10 patients, prediction by the neural network algorithms was compared with the measurement by the real-time position management (RPM) system. The results showed that the neural network algorithm has the excellent accuracy of maximum absolute error smaller than 3 mm, except for the cases in which the maximum amplitude of respiration is over the range of respiration used in the learning process of neural network. It indicates the insufficient learning of the neural network for extrapolation. The problem could be solved by acquiring a full range of respiration before learning procedure. Further works are programmed to verify a feasibility of practical application for 4-dimensional treatment system, including prediction performance according to various system latency and irregular patterns of respiration.

This study is to identify the influence of major variables that affect the participation intention of securities type crowdfunding investors and how participation intention and perceived behavioral control affect investors' herd behavior including indirect effect analysis based on the theory of planned behavior. The ultimate purpose of this study is to understand the investment behavior of securities type crowdfunding investors and to help the relevant parties to develop various policies and business plans to revitalize the system and protect investors. An online survey was conducted on people who are interested or have experience in securities type crowdfunding to receive a total of 276 responses. Excluding outliers, a total of 261 responses were taken into account for the final analysis. For the data analysis, structural equation model analysis using SPSS 22.0 and Amos 22.0 statistical package was conducted. As a result, two of the major variables of the theory of planned behavior-attitude and subjective norm-have been found to have a positive effect on the participation intention of securities type crowdfunding investors. And after analyzing the indirect effect, the participation intention was found to play a mediating role between attitude, subjective norm and herd behavior. However, the perceived behavioral control presented as a major variable of behavioral intention in the theory of planned behavior showed that the effect on participation intention was statistically insignificant. Instead, it was found to have a direct positive effect on herd behavior. This is significant because it empirically confirmed that even if investors perceive securities type crowdfunding as easy to participate, perceived behavioral control does not seem to have a significant impact on participation intention because securities type crowdfunding is an investment in an early-stage business with a high risk of loss. On the other hand, the study has great significance in that it empirically confirmed that domestic securities type crowdfunding investors perceive the funding progress information provided by the platform as a signal and imitate many other investors, showing herd behavior when they actually make an investment. It is expected that this study will provide meaningful insights for the policy making of crowdfunding supervisory offices and platform operators by empirically identifying major variables that influence the participation intentions and herd behavior of domestic securities type crowdfunding investors.

Reusing livestock manure have various advantages in securing soil organic resources. In this study, the N-loading and recycling capacity assessment of animal manure was analyzed by comparing between the cultivated areas of crops and the amount of manure units that are generated from livestock manure. From this assessment, the possibility of recycling resources of livestock manure was evaluated. The amount generated of livestock manure in Gyeonggi-do were evaluated by applying the manure units to the number of livestock manure. The analysis of manure unit per ha shows that the N loading by MU is quite different by region. When it comes to nitrogen loading, the MU per ha of cultivated land in excess of the N-amount was the highest in the Gyeonggi-do province with 2.70 MU/ha, which is higher than the appropriate level. The Chungcheongnam-do province came next with 2.31 MU. So the recycling capacity assessment was carried out mainly based on areas of forage crops, rice that can be provided by recycling livestock manure. The recycling capacity ware highest in Jeollanam-do and Jeollabuk-do. In order to properly apply the livestock manure into organic resources, the seasonal situation that effects the nitrogen demands of crops along with the regional effects crop cultivation should be seriously analyzed. In addition, a system that can effectively produce and manage fertilizer should be established.
