With the rapid development of AI technology, ChatGPT and other AI content creation tools are becoming common, and users are becoming curious and adopting them. These tools, unlike search engines, generate results based on user prompts, which puts them at risk of inaccuracy or plagiarism. This allows unethical users to create inappropriate content and poses greater educational and corporate data security concerns. AI content detection is needed and AI-generated text needs to be identified to address misinformation and trust issues. Along with the positive use of AI tools, monitoring and regulation of their ethical use is essential. When detecting content created by AI with an AI content detection tool, it can be used efficiently by using the appropriate tool depending on the usage environment and purpose. In this paper, we collect data on AI content detection tools and compare and analyze the functions and characteristics of AI content detection tools to help meet these needs.

개인용 컴퓨터와 인터넷의 발달은 교수자와 학습자, 학습자와 학습자의 관계변화를 야기하였으며 대표적으로 전통적인 학습방법으로서의 일대일, 면대면 수업방식은 디지털 기반의 학습모형으로 변화를 죄하고 있다. 이러한 환경의 변화는 새로운 교육 정보로서의 적절한 디자인 도구와 재료의 등장이 교수와 학습, 모두의 입장에서 필요하게 되었음을 의미한다. 본 연구는 디지털 기술 기반에서의 효과적인 기초디자인 수업을 위하여 새로운 형식의 그래픽 툴(Basic Graphic Tools)을 개발하는 데 있다. 전통적인 학습 환경과의 차이는 최소화하면서 디지털 기술에서 가능한 재료와 도구의 다양성을 최대로 이끌어내는 것이다. Basic Graphic Tools(이하 BGTs)는 학생들의 선수 지식 유무와 학습 기술의 편차, 전통적인 훈련 방식과 첨단의 방식이 공존하는 상황에서 학습자에게는 기초디자인 과정에서 요구되는 디자인 원리를 학습하고 시야를 넓힐 수 있는 디지털 디자인 도구로서, 교수자에게는 효율적이고 생산적인 강의를 위한 새로운 교육 도구로 개발되었다. 기초 디자인 훈련프로그램으로서의 BGTs개발과 실험을 통해 새로운 교육 도구로서의 활용 가능성을 살펴보고 기초디자인 교육과정에서 학습자로 하여금 수월성을 갖게 하는 것이다. 기초디자인 학습 툴로서의 신뢰성 향상을 위해 C 대학에 개설된 e강의실을 통해 디자인 작업 일부가 시행되었다. 이를 근거로 Learning Guide/Performance Test가 이루어졌으며 그 결과 매우 높은 사용 가능성을 확보하였고 동시에 추후 연구과제로서 BGTs를 이용한 기초디자인 프로그램의 개발 가능성을 타진하였다.

본 연구는 수학교육에서 중요한 수단이자 교육적 도구인 수학체험교구를 체계적으로 개발하기 위한 기초연구이다. 최근 활동이론(action theory)에 근거한 수학교육이 강조되면서 다양한 수학체험교구가 개발되고 교육현장에서 다양한 비교과활동을 통해 활용되고 있지만, 실제 수학수업에서 개념을 설명하기 위한 도구로 수학체험교구가 개발되어 활용되는 사례는 부족한 실정이다. 특히, 수학과 교육과정에 부합되고, 수학적 근거가 명확한 체험교구는 체계적으로 개발되지 못하고 있다. 이에 본 연구에서는 수학체험교구를 개발하기 위한 체계적인 방법으로 체험교구 개발 모형을 제안한다. 또한 제안한 개발 모형에 따라 최대공약수 체험교구를 개발하였다. 본 연구를 통해 제안된 모형과 실제 구현된 체험교구를 통해 다양한 수학체험교구의 개발이 실제적으로 실행되고, 수학적 기초에 근거한 수학체험교구가 다양하게 개발될 것으로 기대된다.

Background and Objective: The use of potentially inappropriate medications (PIMs) increases the risk of negative health outcomes, including drug-related admissions. Tools for structured medication review have been developed to ensure optimal medication use and safety. Here, we aimed to evaluate medication use review (MUR) tools for community-dwelling older patients. Methods: We performed a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA). We searched PubMed, Embase, and the Cochrane Library from 1991 to 2020, excluding tools that are specifically applied to hospitalized patients or nursing home residents. We identified the most common inappropriate medications, drug-disease interactions, drug-drug interactions and prescribing omissions presented among tools. Results: From among 9,788 identified reports screened, 60 met our inclusion criteria; finally, 27 were eligible for data analysis considering originality and up-to-dateness. Most tools presented explicit criteria (93%), and only one was specific to community-dwelling elderly. The most common PIM was tricyclic antidepressants. Use of diltiazem and verapamil in patients with heart failure and the combination of nonsteroidal anti-inflammatory analgesics and warfarin were the most frequent disease-specific PIM and drug-interaction, respectively. Conclusions: Although several medication review tools have been developed for older adults, specific guidelines for community-dwelling populations remain limited. Furthermore, the list of PIMs differed among available tools. In future, specific but integrating MUR tools need to be developed for clinical practice considering this population.

In order to support the mission of the institution in which they are attached, academic libraries provide services in both manual and digital but COVID -19 pandemic that spanned between March and September, 2020 has changed the scenario. With particular reference to Nigeria, about 249,606 cases were confirmed and in order to curb the scourge of this deadly disease, physical academic activities were prevented by Nigeria Centre for Disease Control (NCDC). With this development, innovative tools became indispensable tools for successful delivery of library services in Nigerian academic libraries. Whether or not these tools are still in use for reformation of library service during post- Covid era remains unclear, hence, need for this study. This study examined librarians' use of innovative tools for information dissemination in Nigerian academic libraries during the post-Covid era using a descriptive survey design. Data were obtained both in quantitative and qualitative formats from one hundred and forty-four librarians as respondents. A total enumeration sampling technique was adopted because the population was minimal. Findings of the study revealed that innovative tools such as videoconferencing, WhatsApp, teleconferencing, Facebook, LinkedIn, and web-based learning applications are still in use by librarians for the dissemination of information during the post-Covid era. These tools are useful and beneficial to librarians during the post-COVID era, as they facilitate easy participation and engagement of library users in various discussions. Inadequate funding and lack of advanced technology skills were also identified as major impediments to the successful use of innovative tools for information dissemination. As a result, it was suggested that academic libraries throughout Nigeria prioritize staff training on the necessary digital skills needed to cope in this advanced technology era.

Purpose: The purpose of this study was to evaluate the psychometric quality and feasibility of measurements for screening dysphagia in older adults to identify the 'right tool' for nurses to use in nursing homes. Methods: A systematic review was done. Electronic databases were searched for studies related to dysphagia screening measurements. A checklist was used to evaluate the psychometric quality and applicability. Tools were evaluated for feasible incorporation into routine care by nurses. Results: 29 tools from 31 studies were identified. Dysphagia screening tools with an acceptable validity and reliability had sensitivity between 68% and 100% and specificity between 52% and 100%. The Gugging Swallowing Screen (GUSS) and the Standardized Swallowing Assessment (SSA) were the tools with high psychometric quality, especially with high sensitivity, that nurses could perform feasibly to identify the risk and to grade the severity of dysphagia and aspiration of nursing home residents. Conclusion: Results show that GUSS and SSA are reliable and sensitive tools for screening dysphagia which nurses can use in nursing homes. Further research is needed to examine feasibility of screening with identified tools, and also, to establish effective and standardized protocols for these tools so they can be effectively incorporated into routine care.

We will improve tools performance without the change of a tools' physical shape, if we process mirror like finishing on the surface of cutting tools. Because cutting tools' shapes are very complex, the general method of polishing can't be polished. So we will apply new method of polishing which is magnetic fluid grinding technique. Magnetic fluid grinding technique can polish complex shape's workpiece by pressing the surface of workpiece with magnetic and abrasive grains in magnetic field. Therefore we developed the polishing equipment to improve the performance of cutting tools and experimented on various polishing conditions to determine the polishing conditions of cutting tools.

Virtual machine tools have been magnified recently as manufacturers could estimate performances of machine tools before design and manufacturing of them. However, it requires much time and efforts to make FEM models and predict precision of machine tools well because machine tools are composed of many joints such as bolt joints, LM joints, rotational bearing joints and mounts. Especially, we have studied computational modeling methods of bolt joints to predict precision of machine tools well in this paper. Stiffness and damping coefficients of bolt joints are investigated and generalized with respect to fasten forces through experiments and FEM analysis. Matrix 27 element of ANSYS is used and bolt joints are simplified as square areas with 8 nodes to apply stiffness and damping simultaneously. Additionally, coordinate transformation of matrix 27 for bolt joints is induced to apply to skewed bolt joints of machine tools and evaluate it using FEM analysis.
