  • In this paper, we propose a simple and relative electrode contact monitoring method. By exploiting the power line interference, which is regarded as one of the worst noise sources for bio-potential measurement, the relative difference in electrode impedance can be measured without a current or voltage source. Substantial benefits, including no extra circuit components, no degradation of the body potential driving circuit, and no electrical safety problem, can be achieved using this method. Furthermore, this method can be applied to multi-channel isolated bio-potential measurement systems and home health care devices under a steady measuring environment.

  • The existing digital signage systems inside the elevators are a lack of tailored contents appropriate to the space and environment inside or outside the elevators. Also, they almost impossible to flexibly respond to various contents disclosure according to the demand of the consumers or the elevator markets. Therefore we design and implement an IoT(Internet of Things)-based smart digital signage system for the safety of elevator passengers.. In order to provide IoT-based information to the smart digital signage within the elevator, we propose an IoT system as a set-top box with gyroscope sensor, acceleration sensor, RFID(Radio-Frequency Identification), fine dust sensor, etc., which processes various data collected by the sensors and provides the elevator passengers with various tailored contents such as elevator driving information, environmental information inside and outside the elevator, and disaster information in addition to simple advertisement information. The proposed IoT system is a set-top box that operates the smart digital signage and has an independent information control processor based on the IoT sensors that do not depend on the elevator control system. For the proposed smart digital signage, it supports an operating system that is independent of the elevator driving service as well as the media service. So the smart signage system has a characteristic that it does not depend on the elevator control system since it is a stand-along IoT-based information control system. With the proposed system providing intuitive content for the surge, steep descent, and radical movements of an elevator due to an emergency situation, the elevator passengers should be able to recognize the situation quickly and respond accordingly. In the near future, the proposed system will expand the market of digital signage applied in conjunction with the development of contents in the disaster, safety and environment fields, and expect expected to revitalize related industries associated with signage.

  • While the life in the fishing villages in old days was characterized by accepting the sea as destiny by birth, it became an industrial one nowadays with industry - scale fisheries as the mainstream. It is expected, however, that nature - friendly life will be prevailing in the fishing villages in the future In these days, the status of fishing village is on a very terrible situation due to the decrease in population, low income, environment destruction, and so on. However, the fishing village should be revitalized because of its public benefits at least. Recently, a kind of affirmative appearance in fishing village is that people who are willing to visit fishing village are increasing. The fishermen are supposed to use this opportunity for its economic and social interests. This paper suggests a kind of way, enjoyable fishery after catching and farming fishery, to use it. Enjoyable fishery consists of watching (learning by observation) fishery and doing (experience) fishery. The example of watching fishery is inspecting the fixed net fishery, doing fishery is experience of small dragnet fishery. The activation devices of the enjoyable fishery are suggested as follows; 1) fixing the identification of regional tourism 2) the development of regional enjoyable 3) opening of one day's fisherman school. 4) networking with fishing village amenity improvement 5) driving sisterhood system with urban area.

  • The Industrial Innovation Movement, based on win-win cooperation with SMEs, is a structure that enables suppliers who have struggled with corporate growth through productivity innovation due to poor manufacturing environment and lack of innovation. To this end, consultants and technical experts will support production innovation activities to improve production methods and improve productivity through process and management consulting. The purpose of this study was to explore the driving factors of the industrial innovation movement to improve the corporate ecosystem by improving the productivity of SMEs using modified IPA. The research results are as follows. First, in order to revitalize the Industrial Innovation Movement, the CEO-related elements of the participating companies should be maintained and strengthened. The motivation, education support, innovation organizational culture, the establishment of an innovation promotion system requires centralization of efforts for improvement. Second, in order to revitalize the Industrial Innovation Movement, the consultant's ability to analyze problems and suggest alternatives should be continuously strengthened. Third, in terms of the Central Promotion Headquarters, it was found that the Industrial Innovation Movement would be successful if the public information, industrial inspection for benchmarking, and provision of various information to support innovation activities were urgently improved.

  • 虚拟社区(virtual community, VC)今年来发展迅速, 越来越多的人参与到虚拟社区中交换信息和分享观点. 虚拟社区是通过计算机布告板和网络进行非面对面的知识和语言交流的一种大众集合体. B2C电子商务网站虚拟社区则是商业性的虚拟社区, 通过培养信任环境来促进消费者在该网站的购买行为. B2CVC通过信息交流, 如推荐, 评论, 买者与卖者评级等, 来建立社会性的氛围. 目前, 虽然学术界已经认识到B2CVC的重要性, 但是关于社区成员的口碑传播行为的研究还不充分. 本研究提出了一个理论模型, 探讨在B2C网站社区中参与度, 满意度, 信任度, 粘度和口碑传播之间的关系. 本研究的目的有三个: 1, 通过整合信念, 态度和行为的测量来实证检验B2C网站社区模型; 2, 更好地理解各因素对口碑传播的影响关系; 3, 更好地理解B2C网站社区黏度在CRM营销中的作用. 研究模型包含以下要素: 1, 社区成员的信念变量, 通过参与度来测量; 2, 社区成员的态度变量, 通过满意度和信任度来测量; 以及3, 社区成员的行为变量, 通过网站黏度和口播传播意愿来测量. 参与度是消费者在虚拟社区的参与动机. 对于社区成员来说, 信息的查找和发布是他们参与到社区的主要目的. 满意度是成员对社区整体评价的重要指标, 反映了成员与社区的交互程度. 虚拟社区的形成与发展依靠成员分享信息和服务的自愿程度. 研究者已经发现信任是促进匿名交互的关键, 因此构建信任被看作是虚拟社区的重要研究课题. 此外, 虚拟社区的成功依靠成员的粘度来提高购买潜力. 社区成员间的观点交流和信息交换代表一种 "写作式" 的口碑传播. 因此口碑传播是推动B2C虚拟社区在互联网上扩散的主要因素之一. 研究模型及假设如图一所示. 本研究通过实证调查中国携程旅游网虚拟社区成员来验证模型. 数据收集过程中共发放243份问卷, 其中有效问卷204份. 通过实证数据验证了参与度, 满意度和信任度影响粘度和口碑传播之间的假设关系. 结构方程模型(SEM)方法用来进行数据分析. 模型的拟合指数结果为χ2/df 是2.76, NFI是 .904, IFI是 .931, CFI是 .930, 以及RMSEA是 .017. 结果表明, 参与度对满意度具有显著的影响(p<0.001, ${\beta}$=0.809). 参与度可以解释满意度的方差比例超过50%, 调整R2为0.654. 参与度对信任度具有显著影响(p<0.001, ${\beta}$=0.751), 解释率为57%, 调整R2为0.563. 此外, 满意度对黏度的影响显著(${\beta}$=0.514), 但是信任度对黏度的影响并不显著(p=0.231, t=1.197). 黏度对口碑传播的影响显著, 且解释率超过80%, 调整R2为 0.846. 总之, 研究结果支持了大部分的研究假设, 但是信任度显著影响粘度的假设没有得到支持. 本研究丰富了电子商务网站虚拟社区的学术研究成果, 深入探讨了在B2C电子商务环境下的用户信念, 态度和行为等因素. 研究成果有助于实践者进行更有针对性的资源开发和市场开拓. 网络营销人员可以针对B2C网站社区来有针对性地制定营销策略, 如对于国际旅游业务, 营销人员可以针对中国的B2C网站社区用户开展营销活动, 如为活跃的用户提供特殊折扣以及为早期参与者提高社区黏度定制营销计划等. 未来的研究应该拓展社区成员行为的研究, 并在不同的行业, 社区和文化背景下开展研究.

  • 최근, 기업 및 공공기관에서는 고객 상담과 응대 분야에 챗봇(Chatbot)서비스를 적극적으로 도입하고 있다. 챗봇 서비스의 도입은 기업이나 기관에게 있어서 인건비 절감 효과를 가져올 뿐만 아니라 고객과의 빠른 커뮤니케이션 효과를 기대할 수 있다. 데이터 분석 기술의 발전과 인공지능 기술의 고도화는 이런 챗봇 서비스의 성장을 견인하고 있다. 하지만 기술중심으로 개발된 챗봇은 사용자가 내재적으로 원하는 바와 괴리가 있을 수 있으므로, 챗봇이 단순히 기술의 영역이 아닌 사용자 경험의 영역에서 다루어질 필요가 있다. 본 연구는 사용자 경험 분야의 대표적 방법론인 디자인 사고 접근법을 챗봇 개발에 적용하여, 사용자 니즈 기반의 챗봇 개발 프로세스를 제안하고자 한다. 사용자 관찰을 통해 팩트(Fact) 수집을 시작으로, 인사이트(Insight)를 도출하고 기회영역(Opportunity)을 발굴하는 추상화의 과정을 수행한다. 이어서 사용자의 멘탈모델에 맞는 기능을 제공하고 원하는 정보를 구조화하는 구체화의 과정을 통해, 사용자의 니즈에 부합하는 챗봇을 개발할 수 있을 것으로 기대한다. 본 연구에서는 제안한 프로세스의 실효성을 확인하기 위하여 국내 화장품 시장을 대상으로 실제 구축 사례를 함께 제시한다. 본 연구는 챗봇 개발 프로세스에 사용자 경험을 접목한 점에서 이론적 시사점을 가지며, 기업이나 기관이 바로 적용 가능한 현실적인 방법을 제안한다는 면에서 실무적 시사점을 가진다.
