  • College students show keen interest in advertising contest, and some contests link with class so that students participate the contest as a class assignment. But the interest is not just limited to students but to businesses. Until now five studies was made on this subject, and major findings of those dissertations are given to activating contest participation, corporate ethics and industrial-educational cooperation. It seems not enough to explain the over-heated phenomenon with the results, so that more research should be made on advertising contest. Required studies with this subject are analyzing the effectiveness relating between investment and result, theoretical establishment by empirical approach, comparative study depending on the style of contest, casual relationship between personal character and image of corporate hosting contest and so on.

  • As contest exhibits have been activated, a variety of organizations are holding contest with various purposes. Analysis on the guidelines prepared by various sponsoring bodies ranging from public organizations to privately owned businesses shows that sponsoring bodies tend to possess copyrights of entries. Parts of guidelines of contest exhibit are the contract. While sponsoring body shows its opinion on copyright through guidelines, individual participant tends to consider it simply as a form to submit for contest exhibit rather than a contract. Now is the time to bring out a question in respect of the copyright on the contest exhibit. The important fact is that copyright on corporate contents is important, but copyright on individual contents is equally important and it must be protected and respected. This study aims to bring out a question on copyright by analyzing possession and infringement of copyright that stands forth in the guidelines of contest exhibit. Provisions on copyright of contest exhibit play a role as a contract. Provisions on copyright of contest exhibit shall be the ones which can be understood and accepted by both sponsoring body and winner who are the A and B of a contract. For this, change in perception of sponsoring bodies ranging from public organizations to privately owned businesses with prominent position is strongly required. For the foregoing, First, Indication of Copyright: Clear and concrete terms must be used. Second, Scope of Interpretation: Concrete and detailed indication must be made for preventing indication that allows comprehensive interpretation. Third, Cost for Author's Property Right: In case sponsoring body needs to possess or use the author's property right of prize-winning work, proper rights on use considering prize money corresponding to possession or use of author's property right must be indicated. Fourth, Term of Use: The term for using author's property right must be indicated. Fifth, Scope of Rights: The scope of author's property right that sponsoring body requires must be limited and indicated. Sixth, Mutual Respect: Items related to copyright must be indicated on the basis of the concept of bilateral contract founded on mutual consideration and respect, not on the concept of unilateral contract.

  • This study aims to report on the problems of the Korean woodcraft in the past and to suggest a new direction for the development strategy, in line with the government policy to promote domestic craft culture industry. This includes the problems of the woodcraft in Korea which have been raising in contest-exhibits organized not only by industry and academia, but also by government. The survey asked 48 people (24 in industry and 24 in academia) shows as follows. The most serious problem shown in industry is the government-sponsored issue and it should be premised on offering the market in this case. The question in academia reports that the academic world little contributes to the development in industrial circles of the woodcraft, and the problematic issues of the contests are the appraisal standard and the method of evaluation. In brief, the government's aggressive support should be always first and foremost for the woodcraft industry which is often confronted with difficulties in research & development and in securing distribution channels due to it' small scale of business. Furthermore, the government-led contest and certificate of qualifications should be redesign for filling the original purpose and throughly carried out for the development of industries. Also university curriculum being far too disconnected from industries now should be focused on the collaboration between industry and university, the training mission and the related seminars to overhaul the contents of the department of the woodcraft and to create a progressive direction for the future accordingly.

  • In this study, a deep convolutional neural network (DCNN) model is proposed for short-term precipitation forecasting using weather radar-based images. The DCNN model is a combination of convolutional neural networks, autoencoder neural networks, and U-net architecture. The weather radar-based image data used here are retrieved from competition for rainfall forecasting in Korea (AI Contest for Rainfall Prediction of Hydroelectric Dam Using Public Data), organized by Dacon under the sponsorship of the Korean Water Resources Association in October 2020. This data is collected from rainy events during the rainy season (April - October) from 2010 to 2017. These images have undergone a preprocessing step to convert from weather radar data to grayscale image data before they are exploited for the competition. Accordingly, each of these gray images covers a spatial dimension of 120×120 pixels and has a corresponding temporal resolution of 10 minutes. Here, each pixel corresponds to a grid of size 4km×4km. The DCNN model is designed in this study to provide 10-minute predictive images in advance. Then, precipitation information can be obtained from these forecast images through empirical conversion formulas. Model performance is assessed by comparing the Score index, which is defined based on the ratio of MAE (mean absolute error) to CSI (critical success index) values. The competition results have demonstrated the impressive performance of the DCNN model, where the Score value is 0.530 compared to the best value from the competition of 0.500, ranking 16th out of 463 participating teams. This study's findings exhibit the potential of applying the DCNN model to short-term rainfall prediction using weather radar-based images. As a result, this model can be applied to other areas with different spatiotemporal resolutions.
