In this paper, we introduce ETRI AI Strategy #3, "Leading Future Technologies of Network, Media, and Content." Its first goal is "to innovate AI service technology to overcome the current limitations of AI technologies." Artificial intelligence (AI) services, such as self-driving cars and robots, are combinations of computing, network, AI algorithms, and other technologies. To develop AI services, we need to develop different types of network, media coding, and content creation technologies. Moreover, AI technologies are adopted in ICT technologies. Self-planning and self-managing networks and automatic content creation technologies using AI are being developed. This paper introduces the two directions of ETRI's ICT technology development plan for AI: ICT for AI and ICT by AI. The area of ICT for AI has only recently begun to develop. ETRI, the ICT leader, hopes to have opportunities for leadership in the second wave of AI services.

The purpose of this study was to explore how consumer traits(technology anxiety and need for interaction) explain attitude toward self-service technologies in fashion retail stores. We examined if technology anxiety influences perceived productivity and attitude toward self-service technologies, and if so, how the need for interaction with employees moderates the impact of technology anxiety on perceived productivity and attitude. For the purpose of the study, a web-based survey with Korean consumers was conducted. The final sample size was 214. Structural Equation Modeling Analysis and PROCESS in SPSS were employed to test the proposed hypotheses. The findings indicated that technology anxiety negatively affected perceived productivity and attitude toward self-service technologies in which perceived productivity affected attitude positively. Need for interaction with employees was found to moderate the relationship between technology anxiety and perceived productivity. It also moderated the relationship between technology anxiety and attitude. This study contributes to the self-service technology literature by identifying two antecedents of consumer attitude toward self-service technologies: technology anxiety and the need for interaction. The findings further provide valuable insights to retailers and marketers as to how technology anxiety, perceived productivity, and the need for interaction work in enhancing consumer attitude toward self-service technologies in the context of fashion retail.

Due to the phenomenon of aging, a new consumer segment known as the "new-silver generation" is emerging. Unlike the previous silver generation, this generation possesses significant economic power and consuming willingness, attracting attention from consumer goods companies. However, both the new-silver generation and the elderly face challenges in adopting contactless or self-service technologies such as self-order kiosks, resulting in negative reactions. Therefore, this study aims to investigate the attitude and response of the newsilver generation towards kiosks, as well as the factors influencing their resistance to such technology. By applying theoretical perspectives from the innovation resistance model, technostress theory, and the value-based model, this study identifies influencing factors for innovation resistance among the new-silver generation when using contactless technologies implemented in fast-food restaurants. The findings indicate that a lower awareness of new technologies and services corresponds to decreased adoption resistance, while a higher perceived value leads to more positive behaviors and attitudes among the new-silver generation utilizing kiosks at fast-food restaurants.

Future MEMS systems will be composed of larger varieties of devices with very different functionality such as electronics, mechanics, optics and bio-chemistry. Integration technology of heterogeneous devices must be developed. This article first deals with the current development trend of new fabrication technologies; those include self-assembling of parts over a large area, wafer-scale encapsulation by wafer-bonding, nano imprinting, and roll-to-roll printing. In the latter half of the article, the concept towards the heterogeneous integration of devices and functionality into micro/nano systems is described. The key idea is to combine the conventional top-down technologies and the novel bottom-up technologies for building nano systems. A simple example is the carbon nano tube interconnection that is grown in the via-hole of a VLSI chip. In the laboratory level, the position-specific self-assembly of nano parts on a DNA template was demonstrated through hybridization of probe DNA segments attached to the parts. Also, bio molecular motors were incorporated in a micro fluidic system and utilized as a nano actuator for transporting objects in the channel.

In this paper, we have recently created self-driving cars and self-parking systems in human-friendly cars that can provide high safety and high convenience functions by recognizing the internal and external situations of automobiles in real time by incorporating next-generation electronics, information communication, and function control technologies. And with the development of connected cars, the ITS (Intelligent Transportation Systems) market is expected to grow rapidly. Intelligent Transportation System (ITS) is an intelligent transportation system that incorporates technologies such as electronics, information, communication, and control into the transportation system, and aims to implement a next-generation transportation system suitable for the information society. By combining the technologies of connected cars and Internet of Things with software features and operating systems, future cars will serve as a service platform to connect the surrounding infrastructure on their own. This study creates a research methodology based on the Enhanced Security Model in Self-Driving Cars model. As for the types of attacks, Availability Attack, Man in the Middle Attack, Imperial Password Use, and Use Inclusive Access Control attack defense methodology are used. Along with the commercialization of 5G, various service models using advanced technologies such as autonomous vehicles, traffic information sharing systems using IoT, and AI-based mobility services are also appearing, and the growth of smart transportation is accelerating. Therefore, research was conducted to defend against hacking based on vulnerabilities of smart cars based on artificial intelligence blockchain.

싸이월드는 디지털글쓰기를 통한 인간관계 형성이라는 새로운 사회적 현상을 만들어 내었다. 싸이월드는 글쓰기 방식에 있어서 기존의 자기 고백적이고 참회적인 글쓰기에서 자신을 그룹의 중심에 놓고 가상공간의 타자들에게 나를 기술하고 유포하는 방식으로 변화시켰다. 이에 본 연구에서는 디지털시대의 변화된 글쓰기 양상과 자기기술방식에 대해 알아보기 위해 싸이월드를 이용하는 사용자 100명의 미니홈피를 분석, 싸이월드 안의 시각적 이미지가 디지털 글쓰기 방식에 어떠한 영향을 미쳤는지를 살펴보고, 데이터 공유를 통한 글쓰기 방식의 변화를 분석하고, 싸이월드에서 만들어낸 가상화된 가족의 형태가 글쓰기에 어떠한 영향을 미쳤는지에 대해 알아보았다. 연구를 통해 밝혀진 자기고백적 디지털 글쓰기의 특징은 (1)자기기술의 시각화 (2)자기기술의 네트워크화 (3)비밀의 공유방식을 통해 찾아 볼 수 있다. 싸이월드의 글쓰기는 비밀의 아닌 공유를 목적으로 만들어 졌으며 자신이 속한 사회(싸이월드 가족)를 통해 유포되어진다. 공개된 비밀은 치밀하게 준비된 보여짐이기 때문에 타인 신뢰가 바탕이 되어야 하고 따라서 이미지의 사용은 불가피한 것이 된다.

A venturi scrubber is an important element of Filtered Containment Venting System (FCVS) for the removal of aerosols in contaminated air. The present work involves computational fluid dynamics (CFD) study of dust particle removal efficiency of a venturi scrubber operating in self-priming mode using ANSYS CFX. Titanium oxide ($TiO_2$) particles having sizes of 1 micron have been taken as dust particles. CFD methodology to simulate the venturi scrubber has been first developed. The cascade atomization and breakup (CAB) model has been used to predict deformation of water droplets, whereas the Eulerian-Lagrangian approach has been used to handle multiphase flow involving air, dust, and water. The developed methodology has been applied to simulate venturi scrubber geometry taken from the literature. Dust particle removal efficiency has been calculated for forced feed operation of venturi scrubber and found to be in good agreement with the results available in the literature. In the second part, venturi scrubber along with a tank has been modeled in CFX, and transient simulations have been performed to study self-priming phenomenon. Self-priming has been observed by plotting the velocity vector fields of water. Suction of water in the venturi scrubber occurred due to the difference between static pressure in the venturi scrubber and the hydrostatic pressure of water inside the tank. Dust particle removal efficiency has been calculated for inlet air velocities of 1 m/s and 3 m/s. It has been observed that removal efficiency is higher in case of higher inlet air velocity.
