Due to the development of information technology, Convergence and Creative Economy became hot issues. For example, products become more intelligent and services are likely to be connected and integrated around core services or provided as bundle solution. Meanwhile products and services are integrated in the context of mutual supplementation, which leads to Servitization of Products and Productization of Services in many industries. Previous studies have addressed Convergence with different terms and definitions such as Convergent, Multicategory Multifunctional Product, Clouding Service, Bundle and so on from one perspective such as consumers, suppliers or technology according to a wide range of academic approaches. Thus, this study attempted to suggest the most typical convergence products released in the convergence environment and categorize those products. Furthermore, this study has pointed out the problems in the New Product Development Framework discussed in the studies on marketing by taking the situation of the public sector into account and then suggested "New Service Development Framework in the Public Sector" that are different from traditional e-Gov. approach basically and will enable the government to create public information service and provide them to enterprises or citizens. It also emphasized the importance of Business Conceptualization Stage in the framework; argued that there is a necessity of an integrative study from the perspective of technology on the basis of the approach from the perspective of marketing and Policy such as a study of consumer behaviors, design and marketing channel and Policy Integration for the development and dissipation; and furthermore suggested the cases-the development/Diffusion of Transportation Card Service in Seoul and CFC (Call for Collaboration) in Singapore-in order to verify the framework. There is a need to supplement New Service Development Framework so it is able to reflect the distinct characteristics of the public sector from the academic perspective and be used as practical guidelines for SI (System Integration) business to shift into IT Service business. Last but not the least, this study has suggested the limitations and the directions for the future studies.

가정 내의 가전기기들이 디지털화되고 있고, 이것들을 네트워크로 연결하여 원격지에서 제어하는 스마트 홈 관련 기술들이 현실화되고 있다. 이러한 환경에서의 컴퓨팅을 위해서는 응용 프로그램간의 호환성 뿐 아니라 데이터의 호환성, 그리고 이종의 프로토콜간의 연동이 필수적이다 따라서 이를 위한 소프트웨어가 바로 스마트 홈 미들웨어이다. OSGi(Open Service Gateway Initiative)(8)는 장비 연결 및 제어로 얻을 수 있는 유효한 서비스나 여러 미들웨어들 간의 통합을 위한 제반 환경 제공을 목표로 하는 비 표준화 단체로써 OSGi 프레임워크 환경에서 서비스들은 서비스 게이트웨이와 서비스 번들의 life-cycle을 따라 동적으로 전개된다. 본 저자들은 SMF(Service Management framework)(9)를 사용하여 OSGi를 기반으로 한 Smart Home Service Bundle에 관해서 연구하였다.

모바일 시스템에 비해 안드로이드 기반 스마트TV 셋톱박스의 경우 직접 전원 연결을 통한 시스템 전원을 공급받기 때문에 갑작스러운 전원차단으로 인한 메모리기반 파일시스템의 손상이 발생하게 된다. 이를 개선하기 위해 init의 중복 실행을 통해 스마트TV OS 프레임워크가 시작되기 전에 해당 파일 시스템의 손상 유무를 판단하여 시스템 체크를 수행하는 방법에 대해 연구한다.

차세대 이동 네트워크에서는 다양한 무선 접속 기술이 공존하게 된다. 이에 따라, 다양한 무선망을 지원하기 위한 분산방식의 호 수락 제어 구조인 SmartCAC를 제안한다. 우리는 네트워크간 정보 수집이 필요없는 분산방식을 위하여 모바일노드와 네트워크간의 상호동작을 이용한다. SmartCAC는 기본적으로 VHO call과 new call의 구분을 가능하도록 함으로써 VHO call에 handoff를 위해 예약된 채널을 사용할 수 있도록 한다. 또한, 이종망에서 네트워크 필터링을 할 수 있도록 모바일노드의 스피드를 이용한다. 이 때 효율적인 호 수락 제어 방식을 위하여 QoS 요구와 네트워크 사용에 대한 cost를 다룬다. 특히 우리는 이종망의 상태정보를 알 수 없는 모바일 노드가 네트워크의 상태정보를 받아 비교할 수 있도록 확장된 프로토콜을 제시하고, 시뮬레이션 연구에서 복잡도와 프로토콜 효율성에 따른 SmartCAC 평가를 수행하여 복잡도는 낮추고 효율성은 높이는 결과를 얻는다.

본 논문에서는 기존 레거시 웨어러블 기기들을 활용한 CE기기들의 제어 방법을 분석하고 개선 필요 사항들을 도출하였다. 이러한 선행 연구들에서는 추가적인 웨어러블 형태의 기기들을 착용해야만하고, 제어 명령 전송 등을 위한 특정 공간으로 이동해야만 하는 단점이 존재하였다. 이러한 문제점들을 해결하기 위해, 본 논문에서는 일반적인 스마트와치 형태의 웨어러블 기기를 활용하여, 기기를 제어할 수 있는 새로운 형태의 웨어러블 프레임워크를 제안하였다. 이를 통해, 스마트홈 서비스와 효과적으로 연계할 수 있는 시스템 구조와 제안 시스템의 효율성 검증 실험 결과를 소개하도록 한다.

As the utilization of technology in the tourism field becomes familiar, it greatly impacts people's tourism activities. These changes could also affect the behavior of tourists during the pandemic. To investigate consumers' adaptation to the self-service technology (SST) environment during the coronavirus disease of 2019 (COVID-19) pandemic, we adopted a model of absorptive capacity as the main framework for empirical research. To track the social effects of COVID-19, consumers' behavioral intentions for four different points in time are collected. The analysis was conducted using latent growth and structural equation modeling. We set the organizational and environmental characteristics as the first step of the model, with assimilation and trust as a middle step. Intention to use a kiosk is placed at the final step as an exploit. Findings indicate that organizational characteristics and environmental characteristics positively influenced assimilation and trust, except for environmental characteristics. Consumers' assimilation in SST encourages immediate intention to use a kiosk. Consumers' trust in kiosks positively impacts both immediate and continuance intention to use a kiosk during COVID-19.

The continuous information technology and telecommunication (ICT) developments inspire several Saudi Arabia citizens to transact and interact online. However, when using online platforms, several people are likely to lose their personal information to cybercriminals. In the survey, 553 Saudi Arabia citizens and 103 information technology (IT) specialists confirm the expansion of digital economy and the need for smart cities with various services, including e-commerce and solid cyber security. 96.6% of the participants believe Saudi Arabia is digitalizing its economy; yet, 33.3% of the participants believe that residents are uninformed about living and operating in smart cities. Several people (47.29%) with medium internet speed are more aware about smart cities than those with fastest internet speed (34%). Besides, online transactions via credit cards subjected 55.5% of the participants to privacy and security issues. These findings validate the essence of cyber security awareness programs among Saudi Arabia citizens and IT professionals to boost public trust and acceptance of cybersecurity frameworks.

This research proposed a particle swarm optimization (PSO) based seismic retrofit design of moment frame structures using a steel frame assembly. Two full scale specimens of the steel frame assembly with different corner details were attached to one-story RC frames for seismic retrofit, and the lateral load resisting capacities of the retrofitted frames subjected to cyclic loads were compared with those of a bare RC frame. The open source software framework Opensees was used to develop an analytical model for validating the experimental results. The developed analytical model and the optimization scheme were applied to a case study structure for economic seismic retrofit design, and its seismic performance was assessed before and after the retrofit. The results show that the developed steel frame assembly was effective in increasing seismic load resisting capability of the structure, and the PSO algorithm could be applied as convenient optimization tool for seismic retrofit design of structures.
