The purpose of this study is to investigate the possibility of using chatbots as a school library educational tool. In order to achieve the purpose of the study, 116 librarian teachers first investigated the types and contents of education conducted in the school library setting and the perception of chatbots there. In addition, 15 librarians (five elementary, five middle, and five high school) were asked to complete a structured questionnaire after using Google's Bard, Microsoft's Bing, and OpenAI's Nova to find out if it is possible to use chatbots in school library education. As a result, user and reading education chatbots were found to be common in school libraries, and 99% of librarians knew about them in some detail. However, the average chatbot performance by area was 2.9 out of 5 (2.6 points being the lowest). Nevertheless, chatbots are being developed utilizing deep learning methodologies and have excellent performance, and are very effective for content-based library education through problem-solving activities.

국내 게임 시장에서도 점차 멀티 플랫폼인 "스팀"을 통해 선정성이 높은 해외 성인 게임이 출시를 하고 있는 중이며 국내 게임 사용자들도 플레이를 해볼 수 있게 되었다. 하지만 국내에서는 심사기관의 제재로 인해 성인 게임을 플레이하고자 하는 사용자들의 의견과 충돌하고 있다. 따라서 본 연구에서는 해외 게임 심사과정과 현황을 조사하고 사용자 설문조사 결과를 통해 국내 게임 시장이 어떻게 받아들어야 하는지 제시하고자 한다.

Realistic Modeling is to maximize the reality of the environment in which perception is made by virtual environment or remote control using two or more senses of human. Especially, the field of haptic rendering, which provides reality through interaction of visual and tactual sense in realistic model, has brought attention. Haptic rendering calculates the force caused by model deformation during interaction with a virtual model and returns it to the user. Deformable model in the haptic rendering has more complexity than a rigid body because the deformation is calculated inside as well as the outside the model. For this model, Gibson suggested the 3D ChainMail algorithm using volumetric data. However, in case of the deformable model with non-homogeneous materials, there were some discordances between visual and tactual sense information when calculating the force-feedback in real time. Therefore, we propose an algorithm for the Volume Haptic Rendering of non-homogeneous deformable object that reflects the force-feedback consistently in real time, depending on visual information (the amount of deformation), without any post-processing.

Hair styling has a significant influence on human social perception. An increasing number of people are learning hair styling and obtaining hair designer licenses. However, it takes a considerable amount of money and time to learn professional hairstyle and beauty techniques for hair styling. Since COVID-19, there has been a growing need for offline and video lectures due to the decline in onsite training opportunities. This study provides a field practice environment in which real hair beauty is performed in a virtual space. Further, the hairstyle that is most similar to the user's hair taken with a webcam or mobile phone is determined through an image matching system using the speeded up robust features (SURF) method. The matching hairstyle was created into a three-dimensional (3D) hair model. The created 3D hair model uses a head-mounted display (HMD) and a controller that enables finger tracking through mapping to reproduce the haircutting scissors' motion while providing a feeling of real hair beauty.

리 서버란 게임 개발사나 퍼블리셔가 공식으로 제공하는 정상적인 서비스가 아니며 개인이 게임을 변조하여 배포하고 불법 운영하는 서버를 뜻한다. 게임 시장이 성장하고 발전하면서 그만큼 정상적인 게임 운영을 방해하거나 불법으로 기존 게임의 서버를 개설하여 저작권을 침해하는 사례도 적지 않다. 본 논문은 그러한 사례 중 K사의 서비스 종료 게임인 '그랜드체이스'의 프리서버 현황과 게임사의 대처 상황을 조사하고 플레이 경험이 있는 유저들을 주 대상으로 설문을 진행하여 프리서버에 대한 사용자 인식을 파악한 후 이를 바탕으로 적절한 대응 방안을 제시하려고 한다.

The coke oven plant on a steel works has not, in the past, been regarded as a prime user of modern instrument technology. The reason for this perception may be due to the fact that the basic design of the coke battery has been changed little over the years. The recording and analysis of oven pushing force on a routine basis is seen as a means of monitoring plant operation. A torque sensor is set up at the shaft of the rotor for measuring pushing force. Pushing force data which is communicated form torque sensor to staor by telemetry method are shown on MMI(Man-Machine Interface) screen and stored in the database automatically. Perhaps the most important feature is that is allows a problem oven to be identified at an early stage and for corrective action to be taken before it develops into a refusal to push. In this way the mechanical loads imposed on the battery structlure can be held to a necessary minimum, so helping to prolong its service life.

The purposes of this study are in threefold; to explain the interactivity in web site, to extend the Technology Acceptance Model(TAM) in the WWW context, and to examine its relationship with the existing TAM components. We proposed that the WWW is not just web systems but interactive spaces for virtual community. Web interactivity is represented by the two constructs: system interactivity and social interactivity. We extended and empirically examined the TAM for the web context. An individual's attitude toward the use of the web site is significantly affected by the individual's perception about ease of use, usefulness, and system interactivity. At the same time, behavioral intentions to use the web site is highly related to the social interactivity. The results showed that the system interactivity and social interactivity of a web site are important factors in affecting the user's beliefs and behavior intention of such a web site, So web page providers not only have to make the web site useful and easy to use, but also need to design an interactive web page by putting both systemic aspects and social aspects.

기술발전에 따른 혁신제품 및 서비스에 대한 연구는 유용성과 편의성을 중심으로 그 수용 및 저항을 서로 다른 관점에서 보아왔다. 그러나 소비자 혹은 사용자들이 느끼는 혁신제품 및 서비스에 대한 태도와 평가는 수용하려는 측면과 저항하려는 측면이 동시에 작용하며 그 결과로서 사용의도 혹은 구매의도가 결정된다고 볼 수 있다. 이에 본 연구는 혁신제품 혹은 서비스가 갖는 다양한 속성을 기술수용모형(TAM: Technology Acceptance Model) 에서의 지각된 유용성(Perceived Usefulness) 과 지각된 편의성 (Perceived Ease of Use) 개념을 사용자 지각에 기초하여 상대적 이점, 유용성, 편의성, 기술혁신성, 사용법의 변화 인식, 위험지각 등으로 구체화하고 각각의 개념이 수용적 태도와 저항에 미치는 영향을 분석하였다. 아울러 수용적 태도와 저항이 사용의도에 미치는 영향력을 동시에 분석 및 비교하였다. 연구에서 얻어진 결과를 중심으로 혁신제품에 대한 소비자 중심의 관리적 시사점도 제시하였다.
