우리나라는 전세계적으로 가장 많은 원유를 수입하는 국가 중에 하나이다. 그리고 국내 몇몇 항들에 수입한 원유를 육상 시설로 이송하기 위한 원유브이가 설치되어 운영되고 있다. 이러한 상황에서 최근 울산항에서 울산 신항의 개발에 따른 방파제 신설로 기존에 설치되어 있는 원유브이를 이설하고 추가로 1기의 원유브이를 추가로 설치할 예정이다. 이에 따라 이설 및 신설하고자 하는 원유브이의 최적 위치 설정이 필요하게 되었는데 현재 국내외적으로 원유브이 위치 설정에 대하여 일정한 그리고 일관된 기준이 수립되어 있지 않은 실정이다. 본 연구에서는 이러한 실정에서 국내외 원유브이 설치 운영 사례 및 관련 선행 연구 자료를 분석 검토하고, 관련 기관 및 전문가 의견 수렴을 통하여 원유브이 설치 기준을 도출하여 제시하고자 한다.

Recently, Korea government make an effort to make jobs through public information disclosure and a public-private partnerships. In this regard, the MOLIT (Ministry of Land, Infrastructure and Transport) is pushing the V-World Business. The V-World is the public platform for the government to disclose spatial and adminstration information. However, the V-World is still not been able to fulfill the role of a public platform, private partnerships window, Warehouse jobs. So, the molit is promoting the V-World advanced project, creating a long-term plan. This study performed a user satisfaction survey and analysis, this result are used as a basis data of the efficient execution of the V-World advanced project and creating long-term planning. Also, we suggested V-World Service Improvement, Open API Service Improvement, future service direction. This study improve the current the V-World, will be utilized as basic data of improving utilization of the use.

As communicating with friends by recording their daily lives in video clips has become a trend for the Z-generation or the Millennial generation, interest in the vlog is increasing. This study analyzed the effects of motivation and user characteristics on use satisfaction and intention to use vlog in 168 participants in their 20s and 30s who have experience using YouTube vlog. The results of the study showed all hypotheses established in this study were adopted. Specifically, habits and killing time, information-seeking, entertainment and relaxation, voyeurism, openness and emotional identification were found to have a positive effect on the use satisfaction. Also, satisfaction with the use of vlog has a significant impact on continuous use intention. Therefore, it can be seen that exploring the vlog will provide theoretical and practical implications.

This study research how beginner utilization guild is made of beginner utilization guild for expanding the V-World. We classified the subjects and investigated the purpose of the visit through satisfaction surveys, Depending on the purpose of the visit, we categorize a beginner, intermediate and advanced user of the V-World visit. This paper studies making beginner utilization guild in the majority of visitors of using map-based services. We carried out analyzing function of the V-World, configuration beginner utilization guild, creation contents, making guild. The V-World is a public service that the spatial information of having built of the country provide to Citizens.

Korea is one of the world's major oil importers. And a few domestic ports are operating SBMs for transferring imported crude oil to shore facilities. Recently, Ulsan port is planning to install additional new SBM and to move the existing two SBMs to other places according to the establishment of breakwater caused by the development of Ulsan New Port. However, there are no systematic and consistent standards for fixing the most suitable position domestically and internationally. This study aims to propose the standard of SBM installation using SAW after analyzing the examples of SBM operation and previous researches at home and abroad, and proposing the distribution rate based on opinion survey of exports and related organizations.

해상용 브이 시스템은 안정적인 전력공급이 필요하다. 현재 해양시설물은 독립적인 전력 시스템을 위해 태양광 발전을 많이 이용한다. 태양광 발전은 많은 분야에 쓰이고 있지만, 해상에서는 육상에서 만큼의 효율을 갖지 못한다. 또한, 날씨가 흐리거나 밤에는 발전을 할 수 없기 때문에 발전량이 낮아지는 문제가 발생한다. 이를 보완하기 위해 파력 발전과 태양광 발전을 함께 사용하여 복합발전 시스템을 구축하였다. 본 논문은 복합 발전 시스템을 통해 해상용 브이 시스템에 안정적인 전력 시스템 구축을 위한 연구를 수행하였다. 실험을 통하여 태양광 발전과 파력 발전이 상호 보완적임을 증명하였고, 해양 시설물에 복합 발전 시스템의 적용 가능성을 입증하였다.

Ocean buoys are operated for safe navigation and collecting ocean data. Recently, to reducing marine buoy's damage by ocean weather's bad condition and collision with vessels has been conducted in several field research. This paper's experiment is buoy condition monitoring about predefined data form by users. As a result using Wireless remote control board applying a radio signal processing algorithms, it can observe buoy's state at an interval of three minutes on the land. Acquired data type is changeable according to ocean weather condition or buoy's purpose of using in advance. Also, this paper conducted an experiment such as data-transmission's stability and wireless communication's availability. As results of the analysis of the transmitted data, the solar, wind and wave power indicates the maximum amount of power, 50 W, 20 W and 40 W respectively. The communication system proven through this research can apply to buoy or other ocean facility.

This study attends to the phenomenon of major domestic corporations advertising their respective brands on official YouTube channels, reflecting the increasing importance of YouTube as a medium for marketing communication. One hundred vlogs of corporations with an official YouTube channel were content analyzed and their banded content attributes, advertising model's characteristics, advertising appeals, creative strategy, and consumer responses were investigated. Results show that the vlogs of employees were generally formulated with information on their colleagues' tasks and interviews. Findings also demonstrate that the characteristics of the model featured in vlogs had the most significant effects on consumer responses. Amongst the creative strategies, the user image had positive effects. However, branded content characteristics and advertising appeal types were found to have relatively weak effects. This research offers a theoretical understanding of the factors that influence consumer responses to the new type of advertising, corporate vlogs, in terms of branded content characteristics and advertising strategies. From a strategic point, it is anticipated that the reinforcement of user image and the utilization of an attractive model will produce positive responses from consumers.

This study investigated the influences of Vee diagram and regulative metacognitive learning strategies upon 6th-graders' achievement, difficulty toward science lesson, self-efficacy, and learning approach. The Vee diagram and regulative metacognitive learning strategies were modified in a pilot study. Before instruction, an achievement test was administered, and its score was used as a blocking variable. A previous science grade was used as a covariate for post-achievement. Tests of difficulty toward science lesson, self-efficacy, and learning approach were also administered, and the test scores were used as covariates. After instruction, a researcher-made achievement test and post-tests of the above variables were administrated. Two-way ANCOVA results revealed that although there were no significant differences in the achievement test scores, the application subtest scores of the two treatment groups were significantly higher than those of the control group. There were no significant differences in the difficulty toward science lesson and learning approach, but self-efficacy scores for the students with Vee diagram and regulative metacognitive learning strategies were significantly higher than those of the other groups. The perceptions of the students using Vee diagram were also analyzed.

The V-world, Spatial information open platform map service, provides various national spatial data. Recently, with the development of IT technology, demand for 3D geospatial data that can be merged with new industries such as Internet of Things(IoT) and autonomous vehicles is increasing. Because 3D geospatial data is large and complex, many computer resources are used to provide map services. Most of the 3D map services, such as Vworld, are constructed binary data in consideration of performance. However, this type of data is incompatible because it is difficult to use in other services if there is no precise understanding of the specification. In this paper, we propose a data serialization method to improve the compatibility of new Vworld 3D format which is constructed in binary form. The performance of binary data and serialized binary data is tested and compared. As a result, it is expected that the data using the serialization technique will be similar to the binary data and contribute to improve compatibility.
