This study focused on social connection apps and support among various measures to prevent 'killing and abandonment of infants', which has recently become a social issue. The research method attempted to show the necessity of a social-linked app by analyzing the contents of 12 cases with peculiarities in the infant murder process in the judgment after 2021. Infanticide mothers were found to be economically and socially vulnerable, and they killed infants to continue their lives. Focusing on the mind of human respect rather than the judicial meaning of punishing crime, the development of social connection apps and support services that allow both mothers and infants to be healthy and socially protected were proposed. The first is a great transformation of economic support and awareness for pregnancy, childbirth, and parenting. Second, it is necessary to develop a confidentiality counseling and information app that can comprehensively support medical directions and social welfare in consideration of the health status of the fetus and women and the socio-economic situation. Third, it is proposed to promote the use of the Internet such as joint childcare facilities of social communities, child protection institutions, and adoption systems. The government should investigate the reasons for not being able to register birth, the root causes of killing and abandonment of infants, and come up with practical plans and policies for them.

In digital marketing, the strategic use of emojis in social media advertising, particularly on the Xiaohongshu app, significantly influences consumer acceptance and purchase behavior. This study examines the impact of emoji-laden advertisements and the role of brand metaphorical warmth on consumer perceptions. Employing a tailored questionnaire, the research explores how emojis affect brand advertisement reception, filling a gap in empirical research on emoji advertising effectiveness. Findings indicate that emojis, when used judiciously, enhance consumer acceptance and contribute to a positive brand perception. However, excessive use may undermine trust. Brand metaphorical warmth emerges as a crucial factor, suggesting that emojis can effectively convey warmth, fostering a deeper emotional connection with consumers. These insights offer practical implications for refining social media marketing strategies, advocating for a balanced approach to emoji usage in advertisements to optimize engagement and influence consumer behavior.

본 논문에서는 안드로이드 앱을 사용한 원격 데이터베이스 모니터링의 시스템을 제안한다. 기존 원격 데이터베이스 모니터링 방식은 CS(Client/Server) 기반이다. 기존 CS기반의 시스템은 공간적인 제약과 다수의 관리자의 접근시 데이터베이스 성능을 저하시킬 수 있다는 단점이 있다. 본 논문에서 제안한 시스템의 장점은 첫째, 웹 애플리케이션 기반 인터페이스를 사용하기 때문에 프로그램 유지보수의 용이하며 또한, 웹 브라우저를 통한 인터넷 접속이 가능한 환경이라면 언제 어디서든 시간과 공간의 제약 없이 모니터링이 가능하다. 둘째, 제안한 시스템은 앱 기반의 기술이므로 연결세션과 질의수행 증가로 인해 데이터베이스 성능에 영향을 미치지 않는다. 셋째, 원격 데이터베이스에 문제가 발생할 경우 이를 소셜 네트워크를 통해 관리자의 스마트 폰으로 즉시 통보하므로 관리자가 해당 문제를 실시간으로 확인할 수 있다.

Purpose This study aims to analyze the current status of consumer awareness on Internet banks by conducting a full investigation and collecting user opinions presented on Google Play. After cateogorizing the current dissatisfaction, we would like to present not only the direction of the Internet bank service of but also the improvements of the platform. Design/methodology/approach Using opinion mining, subjectivity analysis, polarity analysis, and polarity information analysis of comments were conducted step by step to extract negative and positive keywords. The extracted keywords analyzed the weights of the frequently appearing positive and negative keywords using the TF-IDF model. Based on previous studies that negative information is more sensitive to positive information, we tried to confirm the connection, proximity, and mediation of negative keywords. Semantic Network Analysis (SNA) was used to visualize the connection relationship between the negative comment keywords of the three Internet banks. Findings Domestic Internet banks such as Kakao Bank, K-Bank, and Toss Bank have attracted a lot of attention even before they were established, and after establishment, they have secured a wide range of users through platforms that are completely different from existing banks. This study found out that the convenience of the app affects the opening and transaction of non-face-to-face accounts, which are characteristics of domestic Internet banks, which also affects the bank's business strategy. In addition, this study shows that the business characteristics of the company can be identified.

SNS(Social Networking Service)와 쇼핑몰을 결합하면 오프라인 거래에서처럼 단골 관계를 형성할 수 있다. 농산물 직거래의 예를 들면, 소비자는 자신의 SNS 홈에서 기존의 단골 관계인 생산자의 소식(파종, 농사, 수확, 신상품 등)을 타임라인에서 확인하여 필요한 상품을 원클릭(one click)으로 구매할 수 있고 생산자는 소비자에게 뉴스 및 할인 등의 정보를 제공하여 단골로 만드는 고객 관리가 가능하다. 이처럼 SNS의 인맥 마케팅 기능에 더하여 시스템은 생산자의 판매 물품을 자동 분류한 카테고리로 소비자의 SNS 홈 페이지에 쇼핑물의 기능을 제공하여 소비자가 원하는 상품을 검색하고 구매할 수 있으며 구매는 자동으로 소비자와 생산자를 단골관계로 이어준다. 구매자는 구매한 상품에 대한 추천 및 리뷰 작성을 통해 기존의 리뷰 재배포도 가능하며 서로 알지 못하는 구매자 간의 소통을 가능하게 한다는 것이 이 시스템의 가장 큰 특징이다.

Objectives: The aim of the present study was to assess the frequency of use, and preferences regarding information and communication technologies (ICTs) among Ecuadorian patients with chronic kidney disease (CKD) undergoing hemodialysis. Methods: We conducted an anonymous cross-sectional survey-based study from January 2016 to April 2017, involving 393 patients with end-stage renal disease from 9 hemodialysis centers, in which they rated their use and preferences of various ICTs through a modified version of the Michigan Questionnaire. The questionnaire collected information regarding demographics, patients' interest in obtaining health-related information through ICTs, and interest in using ICTs as a potential way to communicate with their healthcare providers. A chi-square test for association and adjusted regression analyses were performed. Results: Among all patients who participated, 64.3% reported owning a cellphone, with less than a third reporting active Internet connection. The most used ICT for obtaining information about CKD and/or hemodialysis was web-based Internet, followed by YouTube. SMS was rated the highest to receive and seek health-related information, followed by Facebook. Younger age and higher levels of education were associated with a higher overall usage of ICTs. Finally, more than half of the patients reported interest in using WhatsApp for communicating with their healthcare providers. Conclusions: Understanding the preferences of ICTs among patients with CKD undergoing hemodialysis could help to improve their outcomes through the potential uses and benefits of ICTs. Further research is needed to assess their role in improving the care of patients with chronic diseases.

Smart phone zombie or Smombie means pedestrians who walk without attention to their surroundings because they are focused upon their smart phone. Because the traffic accidents and injuries caused by Smombie have been increased rapidly in recent years, the social attention and policies are needed to prevent it. This study was conducted to analyze Smombie's current status and some solutions used before and to propose new improved method through the latest ICT trend. In this study, we did the field survey to check Smombies at several places in Seoul through people counting, and found that a lot of pedestrians still use the smart phone while walking. And we analyzed many case studies about some solutions to prevent Smombies previously. The case studies include legal regulations, government policies, smart phone app services and facilities that are used before. We studied them through internet searches and reference studies and we also checked the current operating situation as visiting several places that the solutions actually has been operated. Therefore, we found there are some limitations in previous solutions in terms of effectiveness and management. To consider new solution that can be expected to overcome the limitations, we analyzed the latest ICT trends focused on features to utilize the Smombie prevention, especially video recognition and digital signage. In these days, video recognition has been developed rapidly with assistance of AI technology and it can recognize the specific pedestrian's characteristics such as holding smart phone as well as hair style, clothes, backpack and etc. On the other hands, the digital signage is the convergence device that includes big display, network connection and various IoT sensors. It can be used as public media in many places for public services as well as advertising. Through these analysis results, we show the requirements and the user scenario for the improved method to prevent Smombie. Finally, we propose to develop R&D technology to recognize Smombie exactly as pedestrian attributes and to spread creative contents to increase pedestrian's interest and engagement for Smombie prevention through digital signage.
