This research investigates the pivotal role of AI-enabled technologies in vitalizing the local economy. Collaborating with a leading search engine company, we examine the direct and indirect of an AI-based location search service on the success of sampled 7,035 local restaurants in Gangnam area in Seoul. We find that increased use of AI-enabled search and recommendation services significantly improved the selections of previously less-discovered or less-popular restaurants by users, and it also enhanced the stores' overall conversion rates. The main research findings have contributions to extant literature in theorizing the value of AI applications in local economy and have managerial implications for search businesses and local stores by recommending strategic use of AI applications in their businesses that are effective in highly competitive markets.

최근 사회구조의 복잡화, 산업구조의 다변화, 기후변화 등에 의해 자연재해 및 산업재해, 도시재난이 급증하고, 그 규모 또한 대형화하고 있다. 이로 인해 에너지, 통신, 교통, 금융 등 공공 인프라의 피해가 급증하면서 작은 재해도 큰 재난으로 변하는 예가 늘어나고 있다. 한편 현대사회에 대한 IT의 관여도가 급속도로 늘어나면서 IT 서비스의 궁극적인 형태이자, 모든 산업을 수용하는 개념의 플랫폼(Platform)이 IT를 넘어서 글로벌 사회의 절대적 지배자로 등장했다. 또한 전 세계 유저들의 관점에서 보면 개개인들이 손에 든 스마트폰이 생활의 모든 분야에 걸쳐 소통, 정보, 쇼핑, 제보, 오락 등 모든 활동의 수단으로 절대적 가치를 창출하고 있다. 이는 스마트폰이 가진 스마트 데이터 생산 및 공유 기능에서 비롯된다. 이처럼 스마트 데이터를 기반으로 한 IT플랫폼이 중요한 위치를 점하지만, 아직 재난관리 분야에서 이를 본격적으로 도입, 활용하지 못하고 있다는 점은 큰 문제이다. 국내의 사정을 보면 다행히 벤처기업들을 중심으로 이 같은 플랫폼 구축 움직임이 시작되었으며, 여기에 활용될 데이터 자원을 창출할 수 있는 솔루션 및 특허기술들 역시 속속 등장하고 있다. 시민들이 재난현장을 스마트폰으로 실시간 공유하면 이 스마트 데이터들이 이미지 및 음향정보, 위치기반(GPS)정보, 시각정보, 3D정보, 빅데이터 정보, 센서정보 등으로 분류되어 플랫폼 안에서 인공지능(AI) 딥러닝 방식에 의해 분석되고, 이를 즉시 재난당국 및 시민들에게 재난긴급문자 등 자동으로 경보로 전해주는 것이 이 플랫폼의 핵심 기능이다. 몇몇 벤처기업이 보유한 특허기술을 기반으로 공공자본이 투입되어 이러한 플랫폼이 구축될 경우 국내 재난관리 수준의 획기적 발전은 물론 전 세계를 시장으로 한 플랫폼 수출 또는 글로벌 재난정보 수집능력에서도 엄청난 힘을 발휘할 것으로 기대된다.

Recently, due to the development of ICT technology, changes to the convergence service platform of information systems are accelerating. Convergence services expanded to cyber systems with 5G communication, IoT, AI, and cloud are being reflected in the real world. However, the field of cybersecurity audit for responding to cyber attacks and security threats and strengthening security technology is insufficient. In this paper, we analyze the international standard analysis of information security management system, security audit analysis and security of related systems according to the expansion of 5G communication, IoT, AI, Cloud based information system security. In addition, we design and study cybersecurity audit checklists and contents for expanding security according to cyber attack and security threat of information system. This study will be used as the basic data for audit methods and audit contents for coping with cyber attacks and security threats by expanding convergence services of 5G, IoT, AI, and Cloud based systems.

This study analyzes the 'performance efficiency' of AI-based reading assistance systems in the field of radiology by measuring their 'time behavior' properties. Due to the increase in medical images and the limited number of radiologists, the adoption of AI-based solutions is escalating, stimulating a multitude of studies in this area. Contrary to the majority of past research which centered on AI's diagnostic precision, this study underlines the significance of time behavior. Using 50 chest X-ray PA images, the system processed images in an average of 15.24 seconds, demonstrating high consistency and reliability, which is on par with leading global AI platforms, suggesting the potential for significant improvements in radiology workflow efficiency. We expect AI technology to play a large role in the field of radiology and help improve overall healthcare quality and efficiency.

In this study, we propose a language and platform to describe and manage the MLOps(Machine Learning Operations) workflow for time series data anomaly detection. Time series data is collected in many fields, such as IoT sensors, system performance indicators, and user access. In addition, it is used in many applications such as system monitoring and anomaly detection. In order to perform prediction and anomaly detection of time series data, the MLOps platform that can quickly and flexibly apply the analyzed model to the production environment is required. Thus, we developed Python-based AI/ML Modeling Language (AMML) to easily configure and execute MLOps workflows. Python is widely used in data analysis. The proposed MLOps platform can extract and preprocess time series data from various data sources (R-DB, NoSql DB, Log File, etc.) using AMML and predict it through a deep learning model. To verify the applicability of AMML, the workflow for generating a transformer oil temperature prediction deep learning model was configured with AMML and it was confirmed that the training was performed normally.

While applying new digital technologies, interest in software and artificial intelligence is quite high. In particular, many changes are being made for the development of software and artificial intelligence in the field of education. From 2025, software and artificial intelligence-related curricula will be applied to public education in elementary, middle and high schools. The Ministry of Education is also conducting various camps to experience software and artificial intelligence in various ways in elementary, middle and high schools before they are applied to public education. Several platforms for experience camps related to software and artificial intelligence are also being used. In this study, we intend to increase the educational efficiency of the learning method for software and artificial intelligence to be developed in the future by designing a model for software and artificial intelligence experiential learning platforms.

In this study, by using Entry text model learning, educational contents for artificial intelligence education of elementary school students are developed and applied to actual classes. Based on the elementary and secondary artificial intelligence content table, the achievement standards of practical software education and artificial intelligence education will be reconstructed.. Among text, images, and sounds capable of machine learning, "production of emotion recognition programs using text model learning" will be selected as the educational content, which can be easily understood while reducing data preparation time for elementary school students. Entry artificial intelligence is selected as an education platform to develop artificial intelligence education contents that create emotion recognition programs using text model learning and apply them to actual elementary school classes. Based on the contents of this study, As a result of class application, students showed positive responses and interest in the entry AI class. it is suggested that quantitative research on the effectiveness of classes for elementary school students is necessary as a follow-up study.

The goal of this paper is to propose the use of machine learning platforms in education to train learners to recognize data biases. Learners can cultivate the ability to recognize when learners deal with AI data and systems when they want to prevent damage caused by data bias. Specifically, this paper presents a method of data bias education using MachineLearningforKids, focusing on the case of AI baseball referee. Learners take the steps of selecting a specific topic, reviewing prior research, inputting biased/unbiased data on a machine learning platform, composing test data, comparing the results of machine learning, and present implications. Learners can learn that AI data bias should be minimized and the impact of data collection and selection on society. This learning method has the significance of promoting the ease of problem-based self-directed learning, the possibility of combining with coding education, and the combination of humanities and social topics with artificial intelligence literacy.

The importance of cultural arts education utilizing digital tools is increasing in terms of enhancing tech literacy, self-expression, and developing convergent capabilities. The creation process and evaluation of innovative multi-modal AI, provides expanded creative audio-visual experiences in users. In particular, the process of creating music with AI provides innovative experiences in all areas, from musical ideas to improving lyrics, editing and variations. In this study, we attempted to empirically analyze the process of performing tasks using an Audio and Music Generative AI platform and discussing with fellow learners. As a result, 12 services and 10 types of evaluation criteria were collected through voluntary participation, and divided into usage patterns and purposes. The academic, technological, and policy implications were presented for AI-powered liberal arts education with learners' perspectives.
