1~10kVA 대의 소형 발전기는 엔진, 알터네이터와 제어기로 구성되어 있다. 소형 발전기의 소음은 주로 엔진에서 발생하며, 이 소음은 전투 중 아군의 위치를 적군에게 노출시킬 수 있으므로 소음 저감이 요구된다. 소형 발전기의 소음을 저감하는 방법으로 차음상자를 이용할 수 있다. 소형 발전기의 경우 이동이 용이하여야 하므로 무게 및 부피가 연료의 소모, 엔진의 내구성 등에 비해 더 중요시 된다. 따라서 본 논문에서는 소형 발전기의 이동의 용이성을 고려하여 사람이 들 수 있는 가벼운 무게의 근접(close-fitting) 차음상자를 설계하고자 한다.

The purpose of this study is to investigate the change of students' perceptions by comparing factors affecting e-learning intention before and after e-learning experience based on longitudinal data. For this purpose, a research study was conducted targeting university students at Y and K universities in Gyeongsangbuk-do. As a result, first, the convenience of learning time, the ease of learning process, and the usefulness of e-learning had an effect on e-learning intention regardless of the learning experience. Second, the convenience of the learning space was different in the perception before and after the learning experience, and it was found to affect the intention to use after the e-learning experience. Third, college students who have experienced e-learning have shown that the ease of learning process has the most influence on their intention to use. The results of this study can provide an effective direction of e-learning activation and provide basic data for longitudinal research on e-learning learners.

360 product photography is one of the realistic media technologies that can observe subjects from various angles as one of the real-world VR production methods. This study examined the effect of 360 product photography on the intention to Continuous Use through the technology acceptance model. The results of the online survey showed that informative, which is the characteristic of 360 product photography, affects both ease of use and perceived usefulness, while reliability and entertainingness affect only perceived usefulness. Internal innovation had an impact on perceived ease, but not on perceived usability. Ease of use, both mediators, had a positive effect on sustained use intention. These findings can be used as a reference for various studies in the field of 360 product photography which is still insufficient. In addition, it can provide strategic implications for the production direction of 360 product photos.

In multi-media, multi-channel era, video viewing using various digital devices via the Internet, not the existing broadcasting network, is emerging as a new broadcasting viewing behavior. OTT service is regarded as the main service of this change of viewing behavior. It is a video service that can seamlessly use any content desired by the user at any time, at any time, any device, any contents, if the Internet connection is available. The purpose of this study is to investigate the factors affecting the satisfaction of OTT service by applying the technology acceptance model (TAM). As a result of analyzing through 303 questionnaires of the early users of OTT service, social pressure, perceived popularity, perceived cost, user reputation, individual innovation, and esthetics set as external factors in this study are partially affects perceived usefulness, perceived ease of use, and perceived enjoyment. In addition, perceived usefulness, ease of use, and enjoyment are directly influencing satisfaction. Based on these results, we discuss the theoretical and practical implications and propose future research direction.

전자책에 대한 사회적인 관심과 다양한 장점에도 불구하고 현재 상이한 전자책 문서 포맷을 사용한 결과 전자책 컨텐츠에 대한 교환 및 공유를 어렵게 하여 결과적으로 전자책의 시장 활성화를 가로막는 가장 큰 장애가 되고 있다. 미국과 일본에서는 이미 관련 표준안을 제정한 바 있으며, 한국에서도 2001년 한국전자책 컨소시엄(EBH의 표준화 분과위원회를 통하여 전자책 산업 표준인 한국전자책문서표준(EBKS)을 제정하였다. 한국에서의 전자책 표준 EBKS는 HTML 및 PDF보다 다양한 장점을 제공하는 XML을 기반으로, 전자책 컨텐츠에 대한 정확한 교환 한국출판환경의 특징 반영, 생성 용이성, 관련 표준과의 호환성 제공 등을 기본 방향으로 한다. 한편 EBKS는 DTD 측면에서 고정된 문서구조, 확장메커니즘 제공, 세로 쓰기 다단 편집 그리고 한글 및 고어 특성 반영 등과 같은 특징을 포함하며, 스타일의 경우 교환을 위해서는 XSL-FO를 이용하여 컨텐츠와 스타일을 분리하고 있으며, 출력을 위해서는 XSL-FO를 권고한다. 그리고 EBKS 메타데이터는 사용의 용이성 교환 및 호환성 등을 제공하기 위하여 한정어(qualifier)를 사용하지 않는 dc-metadata와 확장을 위한 x-metadata로 구성된다. 한편 본 논문에서는 이러한 EBKS의 활용예로 XSL-FO를 이용한 전자책 컨텐츠에 대한 정교한 출력 결과를 제시한다.

With the development of the information and communication technology, tourism items or products based on new technology is created or developed for tourists. This study examines tourist's satisfaction about VR program, "Secret Wind Forest", which is the story of Gotjawal, one of famous Jeju eco-tourism attraction. In order to achieve the study goal, it identified a study model from the previous studies. It collected data using survey from visitors who used VR program. The total of 227 questionnaires was utilized for data analysis. Based on the study model, it accepted five hypotheses (H1~H5), which are as follows. Firstly, individual innovativeness has a significant effect on perceived usefulness. Secondly, individual innovativeness influenced perceived usefulness, and perceived usefulness and ease influenced usage satisfaction. These results have both theoretical and practical contribution in terms of the development to tourist products using VR program. Academics can provide basic theories such as tourism activities, behaviors, and attitudes to tourism consumer-related studies on VR tourism program in terms of content application. Practically, it can help tourist marketers who want to use VR tourism program and content developers who use VR devices to construct VR program stories using tourism resources and to plan and execute contents considering the target market.

This study aims to determine the factors that affect learning satisfaction and continuous use intention in metaverse-based non-face-to-face classes. Therefore, a hypothesis was established based on the technology acceptance model and information system success model, and a survey was conducted from November 22, 2021 to January 03, 2022 for students who had class experience using Gather.town-a metaverse platform. PLS Structural Equation was conducted on 122 copies, excluding the questionnaires with insincere responses. The results reveal that "all platform quality" factors influenced "easiness," "content quality" influenced "usefulness," "easiness" influenced "usefulness," "easiness" and "usefulness" influenced "learning satisfaction," "usefulness" and "learning satisfaction" had a positive effect on "continuous use intention." This study is significant because it empirically analyzes the variables that affect learning satisfaction and continuous use intention in metaverse-based non-face-to-face classes. In follow-up studies, additional research is required on the variables that affect learning satisfaction and continuous use intention targeting various metaverse-based platforms, including Gather.town.
