This study analyzed the creative properties of public service advertisements and public content in outdoor advertising. The results of a case analysis focusing on outdoor advertisements for fundraising are as follows. First, government ministries were mainly found as advertisers. Second, most of the advertising messages were about policy promotion by the government and public institutions, with few public content or public interest messages. Third, in terms of expression, text took up more weight than visual elements, and illustrations were the main visual expression element. This proves that the public content of domestic outdoor advertisements mainly has a strong purpose of conveying direct information.

In order to promote the commercial space activities of the private sector, the Trump Administration announced the commercial space regulatory reforms by issuing the Space Policy Directive-2 (SPD-2) on May 24, 2018, followed by the SPD-3 dealing with a separate issue of the space traffic management on June 18. Both executive orders, based on the recommendations prepared by the National Space Council (NSC) reconstituted in June 2017 and signed by the President, involve regulatory reform policy related to launch services, commercial remote sensing, establishment of one-stop shop office in Commerce Department, radio frequency spectrum, export control, and space traffic management, providing a strong guidance to the Federal Government. The commercial space regulatory reform policy can be seen in broader terms of the National Security Strategy earlier announced on Dec. 18, 2017, and as such, it pursues the economic growth of the U.S. and the national security as well. The U.S. law and policy prioritizing its national interests by promoting commercial space activities may lead to concerns and debate on the potential breach of the provisions of the Outer Space Treaty. Hence, it is worth noting the legal implications as derived from the U.S. space policy and domestic legislation, thereby accelerating international discussion to build on international norms as appropriate to the pr ogress of space technology and space commercialization.

MANET은 노드가 이동성을 가지고 있으며, 네트워크 위상을 자율적으로 결정하는 특성을 가지고 있다. 정책기반 망 관리 시스템을 MANET에 도입하기 위한 연구는 이러한 네트워크 특성을 고려하여 신뢰성과 효율성을 확보하기 위해 이루어지고 있다. 또한, 정책기반 망 관리 시스템은 유선 네트워크를 기반으로 제안되어 있으므로 이를 MANET에 도입하기 위해서는 여러 가지 수정이 필요한 부분이 있다. 정책 기반 망 관리 시스템은 SNMP의 MIB나 LDAP를 이용하는 정책 저장소와 노드의 상태를 수신하여 정책을 배포하는 정책결정자, 그리고 정책을 수신하여 수행하는 정책 수행자 노드가 있다. 본 논문에서는 MANET 라우팅을 이용하고 표준 정책 기반 망 관리 시스템에서 정책 결정자와 정책수행자 사이의 프로토콜로 제안된 COPS-PR을 MANET에 특성에 맞게 수정한 능동적 PDP 탐색 메커니즘을 이용한 테스트베드를 설계하고 구현한다.

The overall focus of this study was to identify marketing and promotion strategies that can maintain and enhance environmentally friendly farm and organic production and processing activities. This is particularly important as the volume of environmentally friendly farm and organic produce that is generally available is increasing, and significant players, such as Organic Marketing Initiatives(OMI) and conventional marketing co-operatives, are becoming involved in the market. The rapid increase in production of environmentally friendly farm products and organic food is creating new and more complex challenges for marketing, from vegetable box schemes large co-operatives supplying the precise quality and volume required by supermarkets. A possible strategy for many farmers is to co-operate in regionally or nationally operating marketing initiatives. The main objective of any public relations(PR) activity should to enhance publicity and to improve an OMIs image. No promotion, no perception of OMI performance.

Nowadays, domestic photovoltaic system market has been expanded and the governmental dissemination policy has been continued. There is only PV system output performance analysis which is called Performance Ratio(PR) analysis. However, there exists many parameters that can affect PV system output. This papers shows the PV system energy performance analysis using meteorological monitoring data. The meteorological monitoring system was installed in the H university and we analyzed the PV system which installed in the H university. We also investigated other three PV systems which located less than 3 kilometers from H university. We evaluated total 4 PV systems through the field survey data, design drawing data and power generation data. Finally, we compared the actual measuring data with the simulation data using PVSYST software.

The total system is composed of the main system (MS) and the failure detection equipment (FDE) which detects failures of MS. The analysis of system reliability is performed when the failure of FDE is possible. Several repair policies are considered to determine the order of repair of failed systems, which are sequential repair (SQ), priority repair (PR), independent repair (ID), and simultaneous repair (SM). The states of MS-FDE systems are represented by Markov models according to repair policies and the main purpose of this paper is to derive the system availabilities of the Markov models. Analytical solutions of the stationary equations are derived for the Markov models and the system availabilities are immediately determined using the stationary solutions. A simple illustrative example is discussed for the comparison of availability values of the repair policies considered in this paper.

The purpose of the study was to perform a comparative analysis of the success and failure cases to increase the completeness of vault "Shirai-Kim Hee Hoon" technique. The subject of the study was "K" a male gymnast from Korean Artistic Gymnastic National team. The results obtained through the three-dimensional analysis during international as well as practice session are as follows: Firstly, excluding BC, the lead time in each PrF, HC and PoF phases were shorter during successful trials than in failure trials. Secondly, during successful trials, the horizontal and vertical velocity appeared to be higher during taking off, which contributed positively to the leaping motion in the horizontal direction. Thirdly, when compared with successful and failure trials, the body's angular rotation was highly maintained during the takeoff from the spring board followed by larger thigh angular displacement at the vault before actually attempting the backward rotation.

The PBNM on MANET is being researched to ensure the reliability and efficiency between mobile nodes. Therefore, it is essential to determine the cluster effectively which will perceive the movements of nodes and distribute the policies. In PBNM mechanism, to determine the node cluster for PDP and manage PEP nodes, Active PDP Discovery Protocol is proposed as a mechanism which is more efficient than preexistent techniques. While k-hop cluster selects the PEP nodes which PDP node manages, Active PDP Discovery actively selects the PDP node among the moving PEP node. This method prevents orphan nodes that are not connected to PDP and reduces continual broadcasting messages. This paper implements Active PDP Discovery which determines cluster in the real networks and analyzes its capability, expanding COPS-PR to detect the movement of nodes and adding MNL to PDP node.

As the media environment surrounding us has changed rapidly, the influences of traditional media decrease whereas promotions using new media have been developing remarkably, Under this circumstance, cross-media advertising, which strategically integrates advertisements on multiple media, is getting attention as an effective marketing communication approach. This study investigated consumer responses to cross-media advertising using both online and offline media, focusing on the effects of product involvement, attributes of media connection, and gender. The experiment was conducted towards adult consumers aged 20 to 39. Results confirmed that the interaction effect between product involvement and attributes of media connection on brand attitude and behavioral intention was significant by a moderating role of gender. Based on the results from this study, both theoretical and practical implications were discussed, as were directions for future research.

The purpose of this study was to examine the effects of age and gender on Eastern and Western cultural values imbedded in online advertising. This study conducted a survey of 180 men and women ages between 10s and 60s who lived in Seoul, Korea. They responded the acceptance degree of six online advertising emphasized three Korean traditional values and three Modern values. Research hypotheses of this study were the acceptance of cultural values in online advertising is different between ages, but similar between gender. The hypotheses were supported as the previous studies. Findings suggest several theoretical and practical implications that convergence between modern and traditional values is a more important variable to study in the research of online advertising.
