This research proposes a concept of multi-aspect Social IoT platform that enables human, machine and service to communicate smoothly among them, as well as a means of an automatic process for transforming exiting domain knowledge representation to generic ontology representation used in the platform. Current research focuses on building a machine-based service interoperability using sensor ontology and device ontology. However, to the best of our knowledge, the research on building a semantic model reflecting multi-aspects among human, machine, and service seems to be very insufficient. Therefor, in the research we first build a multi-aspect ontology schema to transform the representation used in each domain as a part of IoT into ontology-based representation, and then develop an automatic process of generating multi-aspect IoT ontology from the domain knowledge based on the schema.

Digital broadcast environment led to the emergence of UHDTV following HDTV. The demands for realistic images which are created with the use of UHDTV have been applied to various fields. Of various application methods, multiplanar imaging, which is used to display high definition image contents after multiple HD or UHD displays are connected with each other up and down, and left and right, is often applied to display images and the advertising market. Today, the firms that make high-definition multiplanar images mostly use their independently developed program. Therefore, it costs higher than other general works. For the reason, multiplanar image contents are mostly made in the way of enlarging HD images over 2 to 5 times. In this experiment, the software application widely known for UHDTV based multiplanar images is applied to test a method of implementing UHD panoramic realistic images without quality degradation.

The development of digital image technology has realized high definition throughout the image industry including film and broadcasting. Such high definition images are used in various media and forms through convergence with innovative displays. The analog image production mode is combined with image content production using digital technology. The purpose of this research is to present a method to reconstitute high definition multiplanar images on the wider and bigger screen by applying the Cinerama system, one of the analog image systems in the past, to digital technology.

해상 해수면에서 운영되는 등부표의 한정된 면적과 공간에서 전력공급을 할 수 있는 한계가 있다. 정보통신기술(ICT) 발달로 e항로표지, 집약관리시스템등 해양교통시설에 최첨단 기술 접목으로 등부표에 소비전력연동시스템 증가로 인해 절대적인 전력량이 부족하다. 이러한 문제를 해결하기 위하여 비바람으로 인한 사방팔방 격동, 격랑, 회전 요동으로 직달 및 산란광을 태양 전지판에 최대로 입사할 수 있도록 태양의 이동궤적에 따라 자동추적되는 신 구조의 다면구체형 태양광 발전시스템을 개발하였다.

The purpose of this study is to examine the relationship between the Minnesota Multiphasic Personality Inventory(MMPI-2) clinical scales and the self-regulation quotient of the brain quotient. The test in this study was performed by 41 adults over 20 years old and was done using the MMPI-2, which is a self-reporting method. EEG was performed using a 2-channel EEG System at Fp1 and Fp2. The analysis showed a negative correlation between scale 2(D), which is the MMPI-2 clinical scale, and the SRQ(Self Regulation Quotient) relaxation status, which is the related alpha rhythm. Scale3(Hy) showed a positive correlation with the SRQ concentration status and low ${\beta}$ rhythm. Scale7 in the MMPI-2 clinical scales showed a negative correlation with the SRQ relaxation status, which is the alpha rhythm. This means that MMPI-2 and SRQ can be used complementarily in the field of counseling. These results could be interpreted in three ways. First, people with depression are sensitive to other people's attention and evaluation. Therefore, they tend to expend a lot of energy when forming interpersonal relationships, and if they do not learn to relax, their fatigue can easily be increased. Second, people who seek other people's interest and have a cheerful spirit are considered to be highly active. Third, highly stressed people with anxiety and tension seem to easily become tired and their irritation and discomfort may be increased in consequence.

Filming using multiple cameras is required for the production of the multi-screen content. It can fill the viewer's field of view (FOV) entirely to provide an increased sense of immersion. In such a filming scenario, it is very important to monitor how images captured by multiple cameras are displayed as a single content or how the content will be displayed in an actual theatre. Most recent studies on creating the content of special format have been focused on their own purposes, such as stereoscopic and panoramic images. There is no research on content creation optimized for theatres that use three screens that are spreading recently. In this paper, we propose a novel content production system with a rig that can control three cameras and monitoring software specialized for multi-screen content. The proposed rig can precisely control the angles between the cameras and capture wide angle of view with three cameras. It works with monitoring software via remote communication. The monitoring software automatically aligned the content in real time, and the alignment of the content is updated according to the angle of camera rig. Futher, the producion efficiency is greatly improved by making the alignment information available for post-production.

A survey showed that the public perception of the shipping industry's overall image and economic role was relatively positive. The survey revealed that public perception was mixed with respect to the multifaceted role of the shipping industry. Based on the results of this survey, this paper proposes three approaches to improving the public perception of the shipping industry. The organization contact approach includes establishing shipping institutes for city people, holding various events targeted at the public, establishing a shipping memorial hall, developing a shipping-related culture and tourism, reinventing the image of the shipping industry through a shipping-culture movement, and creating new views of the shipping industry by conducting formal education. The goods and services contact approach includes building a brand image for shipping services, providing B2C services, utilizing the national image for the shipping industry, and participating in international cooperation projects. The text contact approach includes B2B advertising, advertisements focused on the national economic and multifaceted role of the shipping industry, package advertisements for the shipping industry and related industries, the Internet and high-technology media, government-initiated PR activities regarding the multifaceted role of the shipping industry, and funding for advertising the shipping industry.

To establish an effective performance appraisal system, ratee accountability is essential because it increases the likelihood of meaningful utilization of performance appraisal feedback. In the context of a multi-rater performance appraisal system, this study examines the effect of the ratee general accountability and accountability to the supervisor and peers on the ratee's intention to change behavior based on the performance appraisal feedback. This study further explored the moderating effect of perceived feedback specificity on the relationship between the ratee accountability and behavioral change intention. Hierarchical multiple regression analysis was conducted using the survey data from 153 employees in eight firms with multi-rater performance appraisal systems. The results showed that ratee general accountability was positively associated with the intention to change behavior. Furthermore, perceived feedback specificity attenuated the positive relationship between the ratee general accountability and behavioral change intention, which was the opposite of the hypothesized direction. The findings indicate the importance of managing and facilitating ratee accountability for implementing a multi-rater performance appraisal system. The result also emphasizes the critical role that performance appraisal feedback plays in motivating performance improvement by providing flexible, constructive advice and behavioral change strategies instead of inducing self-defense or justification.

회사에서 사원 평가 항목에서 다면 평가가 활용되는 경우는 많지만 대부분의 중소기업들은 자체적인 인사관리 시스템이 부재로 인해서 많은 시간과 노력을 필요로 하면서 효율적이지 못하면서 공정하지 못한 평가로 이루어지지 못한 실정이다. 따라서 본 연구는 회사에서 원하는 다면 평가 시스템 구축에 관해서 자동화로 이루어 질 수 있게 한다.
