Domestic digital signage industry has been growing in line with the Internet and intelligent devices like smart phones. However, policies for digital signage need to be supplemented because existing policies are only focused on regulations for outdoor advertisements. Moreover, while digital technologies have been developed, there are few contents technologies to support the digital technologies. In this context, this research aims to identify the problems in relation to the domestic digital signage industry and seek for measures to solve the problems. Various case studies and literature review were conducted to identify problems in terms of policy, technology and service, and measures for revitalizing the digital signage industry were suggested. The research is expected to help digital signage to serve as new convergence media available for customization targeting and user participation.

This paper deals with the development of a simulation model for the container terminal, which consists of 3 berths, 8 container cranes, and 16 yard blocks with each yard crane and 90 yard trucks in order to evaluate the various operational rules. The proposed operational rules are 3 ship-dispatching rules, 3 berth allocation rules, 2 crane allocation rules, 2 yard allocation rules, and 2 yard truck allocation rules. These rules are simulated using 4 performance measures, such as ship time in the terminal, ship time in the port, the number of ships processed, and the number of containers handled. The simulation result is as follows: 1) there is no difference among 3 ship-dispatching rules, 2) berth allocation rules depend on performance measures, 3) dynamic crane allocation is better than fixed policy, 4) pooling yard allocation is better than short distance yard allocation rules, and 5) fixed yard truck allocation by berth is a little better than pooling policy.

The Ministry of the Energy and Resources is planning to invest a great deal of public funds in the energy conservation measures in order to conserve the energy. This study aims at applying the project scheduling model, especially to the energy conservation measures. In the study, we develop the project scheduling model, which is based on the modified Rorie-Savage problem. And the model is applied to the X-enterprise, which is one of the leading metal industry in the nation. The result shows that the model enables the top management to choose the set of projects which promises the largest profit among the entire projects. It appears that the proposed policy of the study is more profitable than the existing policy which is namely based on the qualitative consideration.

Half a century has passed since the academic field of library and information science, which was born at the end of the 19th Century in the Western world, was introduced to Korea. Despite years of quantitative growth and qualitative maturation, the field has been facing the inconvenient truths of discrepancies in education levels arising from varying education providers, and weakened public confidence in librarian certification. Based on analysis of librarian training and education programs and the certification system, this research seeks to point out the limitations of the national librarian certification system, which is losing public confidence, and present a model for improvement. Library and information science education has expanded from universities to the academy of librarian education and lifelong education centers, and the librarian certification system has emerged as a target of reform. This research presents measures to improve the librarian certification system to government bodies and the Committee on Library and Information Policy with the purpose of providing grounds for policy enforcement.

This paper investigates two discrete time queueing inventory models with positive service time and lead time. Customers arrive according to a Bernoulli process and service time and lead time follow geometric distributions. The first model under discussion based on replenishment of order upto S policy where as the second model is based on order placement by a fixed quantity Q, where Q = S - s, whenever the inventory level falls to s. We analyse this queueing systems using the matrix geometric method and derive an explicit expression for the stability condition. We obtain the steady-state behaviour of these systems and several system performance measures. The influence of various parameters on the systems performance measures and comparison on the cost analysis are also discussed through numerical example.

This paper suggests a new paradigm of science and technology (S&T) policy for the purpose of the new national development that pursues not the scale expansion of a industrial production but the qualitative enhancement of industrial and S&T comparativeness. The new S&T policy paradigm includes new policy directions such as the density increasement of high quality- brain power and the energy supply for crossing the threshold from imitative R&D to creative R&D. Also, this paper argues that it is necessary not only to acquire the support of the local S&T community and policy-makers on the new S&T policy paradigm, but also to develop and implement policy measures in details on the basis of the new paradigm suggested by the paper.

Pollution emissions from international shipping and port activities have a significant impact on public health and global climate changes. The purpose of this paper is to review the status of pollution mitigation measures implemented to date in port industry and find out some implications for Korean ports. For this aim, the clean air strategies of the world major ports including six USA ports (Los Angeles/Long Beach, Now York/New Jersey, and Seattle and Tacoma), two European ports (Rotterdam and Gothenburg) and Busan Port were considered. Various measures to reduce emission from ports are evaluated by sectors-ocean going vessels, cargo handling equipments, truck and rail-, on the basis of categories such as reduction control technologies, operational changes and market-based measures. The policy implications of this paper are as follows. First, Clean Air Act Plans of Korean ports are required as soon as possible. Second, integrated approach is required to reduce emission effectively. Finally, the effect of port-related emission reduction can be maximized when various measures are conducted on a regional basis including neighboring ports. Furthermore, regional or global-based approach is useful to guarantee the level playing field among ports.

Due to growth of diversified media, content screening is the definite procedures. The procedures of screening varies from country by country in various reasons. Therefore, reason of conducting such study is to compare & contrast screening process by countries. In order to clarify definition of terms that measures screening, "censorship" means "legislative filtering process prior to public appearance". In contrary "Rating and/or Classification" is defined opposite of it. After defining these terms, Screening is dignified into two distinctive measures, which are "legislative intereference" and "voluntary notification". Those two measures are again sub-categorized into eight distinctive operational definition. Utilizing those distinctive measures, our study has concluded as US, Japan and some laissez-faire countries use "voluntary notification" systems but in contrast China and Brunei use "legislative filtering" system.? Korea and Australia uses unique combination of both system. In order for Korea to adopt "voluntary notification system", legislative intereference must be weaken and develop strong "voluntary notification" system.

For web application vulnerability diagnosis, from the development stage to the operation stage, it is possible to stably operate the web only when there is a policy that is commonly applied to each task through diagnosis of vulnerabilities, removal of vulnerabilities, and rapid recovery from web page damage. KISA presents 28 evaluation items for technical vulnerability analysis of major information and communication infrastructure. In this paper, we diagnose the vulnerabilities in the automobile goods shopping mall website and suggest security measures according to the vulnerabilities. As a result of diagnosing 28 items, major vulnerabilities were found in three items: cross-site scripting, cross-site request tampering, and insufficient session expiration. Cookie values were exposed on the bulletin board, and personal information was exposed in the parameter values related to passwords when personal information was edited. Also, since the session end time is not set, it was confirmed that session reuse is always possible. By suggesting security measures according to these vulnerabilities, the discovered security threats were eliminated, and it was possible to prevent breaches in web applications and secure the stability of web services.

This study intends to present policy proposals to make the transition from policy adjustment system based on hierarchial authority to deal with energy policy to network establishment based on the central government, local government, industry and civic group, that can be converted into governance. To this end, the legal foundation to make the network-based policy adjustment for government's energy policy possible first. Second, contribution should be made to establish governance related to central government's energy policy. Third, contribution should be made to establish governance related to local government's energy policy. Based on this, this study intends to secure policy measures to establish and improve governance related to energy policy in Korea.
