Recently, with the development of biotechnology and molecular genetics, research using human biological materials has been receiving attention, and the demand for the use of human- biological materials has also increased significantly. In particular, human biological materials contain the personal information of the person providing them, so special care must be taken to protect personal information throughout the entire process from drafting the human biological materials research plan, Institutional Review Board (IRB) review, and research progress. In addition, it is important to appropriately utilize residual human biological materials obtained during medical diagnosis and treatment at medical institutions to achieve scientific results, while protecting the rights of human biological materials providers and improving the method of expressing consent so as not to damage the trust of human biological materials providers in researchers. To this end, it is necessary to provide sufficient information and education so that researchers and IRB members can understand and apply related laws such as the Bioethics Act and the Personal Information Protection Act.

Corporate governance has received massive attention in academic research nowadays due to several recent corporate failures. Inefficiency of corporate governance mechanisms have driven the minds of the researchers and the policy makers to look with more insights into this area. Board composition, as part of corporate governance mechanism, plays a significant role to achieve company's goals or objectives and ensure transparency and accountability. The objective of this study is to find out the efficiency of board composition through board size, independent directors and female directors on firm performance in the listed manufacturing firms of Bangladesh. In this study, a sample of 162 firm years are considered as the sample during the period of 2011 to 2016. This study finds that large board is the significant explanatory variable in improving firm performance. This study also shows that board independence and female directors have no significant association with firm performance which implies that instrument of corporate governance mechanism particularly board composition is very weak. This study recommends that code of corporate governance, specially the role of independent directors and female directors, should be reformed in the light of cultural and institutional context along with the effective enforcement.

Information boards installed in Seoul subway stations are currently in four languages: Korean, English, Chinese, and Japanese. Informational announcements are provided to inform the main information or operation information through the LCD monitor installed in the train and in Korean. However, users are confused because the subway guide board screen displays advertisements more heavily than driving information As a research method, we grasped the current status and problems of the subway guide board installed on the Seoul subway, and presented an improved new subway guide board drafts. An online survey was conducted on 67 people, ranging from teens to 60s who mainly use the Seoul Metro. As a result of the study, the screen design is different for each boarding route, so it is necessary to unify the subway guide board that provides only necessary information. In particular, since the user transfers the subway several times in order to move from place to place, the subway guide board design should function as an emergency disaster guide or boarding information, not an advertising signboard.

In this paper, we implemented the sign board that is able to display the located based information by adding the GPS module to the board that display the DARC information and user`s message. The global positioning information from GPS module gets more correct by DGPS from DARC module. This information help this system select the located based information for broadcasting. From the experiment, we confirmed that this system displayed user`s data, DARC information data and located based information.

There are two methods for train control in information transmission by using track circuit system and installing wayside transmitter. Information signal is transmitted to the on-board antenna by using rails. Continuous information about train intervals, speed and route is received by on-board antenna in AF track circuit system. The information signal is included with carrier wave and received by magnetic coupling in the on-board antenna. Therefore, it is important to define standard current level in the AF track circuit system. When current flowed to rails is low, magnetic sensors are not operated by decreasing magnetic field intensity. Hence, SNR is decreased because electric field intensity is decreased. When the SNR is decreased, there is the serious influence of noise upon demodulation. So, the frequency of information signal is not extracted in frequency response. Thus, it is possible to happen to train accident and delay as the information signal is not analyzed in the on-board antenna. In this paper, standard energy density is calculated by using Parseval's theory in UM71c track circuit. Hence, detection time of information signal is presented.

Internet bulletin boards have been used to exchange their idea and information among Internet users. But the existing Internet bulletin boards can not satisfy user's personal view. In this raper, Web 2.0 based customized Internet bulletin board is to design. The proposed Internet bulletin board provides each user with personalized information which are established by user beforehand. So user can retrieve his interested information fast. Moreover user can generate his own personalized bulletin board to collect one's interested information automatically. The personalized bulletin board is connected to several Internet bulletin boards with RSS feeds.

Previously, in order to send information from the local controller to the display board, the hardware or software had to be handled and run through 3-phases, which include the PC-card or PC-add Board, I-F card and Sub board. This study will attempt to design a board that handles information by connecting the USB port of the PC directly to the Sub board. In addition, an MPU will be attached to the previously complex hardware circuit to design a software drive engine module, which allows for the development of new products by modifying only the software engine and not the hardware.

In this paper, I analyze the success factors of the mobile game "Marble for Kakao", and propose the factors that should be emphasized when converting the board game to digital. has converted to digital game using board game widely known in Korea. At this time, it differs from the existing , reducing the time required to play the game once, allowing the user to concentrate for a short period of time by giving a visual expression, and to repeatedly play the game several times. It also allows users to experience a variety of maps and character enhancement systems so that they can continue to be interested. Thus, Marble for Kakao has optimized the digital environment, not digitally portraying existing board games.

Monte-Carlo GO is a computer GO program that is sufficiently competent without using knowledge expressions of IGO. Although it is computationally intensive, the computational complexity can be reduced by properly pruning the IGO game tree. Here, I achieve this by using a potential model based on the knowledge expressions of IGO. The potential model treats GO stones as potentials. A specific potential distribution on the GO board results from a unique arrangement of stones on the board. Pruning using the potential model categorizes legal moves into effective and ineffective moves in accordance with the potential threshold. Here, certain pruning strategies based on potentials and potential gradients are experimentally evaluated. For different-sized boards, including an official-sized board, the effects of pruning strategies are evaluated in terms of their robustness. I successfully demonstrate pruning using a potential model to reduce the computational complexity of GO as well as the robustness of this effect across different-sized boards.
