Purpose The purpose of this paper is to explore the differences in the external factors influencing intention to donate via social network sites (SNSs), and the online donation knowledge and awareness effect on the willingness to donate via SNS in the future between Malaysian and South Korean users. Design/methodology/approach In total, 288 samples’ data obtained from online survey using the snowball technique were analyzed through using cross-tabulation with χ 2 tests and multiple regression an

The relationships between pipe breaks of service pipes and mains and several factors were examined. Historical pipe breaks, and water and soil temperatures were also modeled by an artificial neural network to predict pipe breaks for efficient management and maintenance of the pipe networks. It was observed that the breaks of pipes increased after the temperatures of water and soil crossed in spring and fall. The pipe breaks were closely related to water and soil temperature, especially mains wer

This study aimed to examine how information quality (IQ) attributes affect perceived usefulness and customer satisfaction of SNS-based commerce from the perspective of Malaysian SNS users. Although many studies have been conducted to identify possible IQ attributes in the context of e-commerce, only a limited number of studies have tested and examined the direct effects of the IQ attributes on perceived usefulness and customer satisfaction, particularly in the s-commerce context (i.e., SNS-based

Although the information systems success model has been used widely in measuring the success of e-commerce, limited studies have been conducted focusing on identifying service quality (SQ) determinants that lead to the e-commerce success particularly s-commerce. This study examines the effect of SQ determinants on social networking site (SNS)-based commerce in the s-commerce context from the customer’s perspective by adapting the IS success model and combining it with a modification of SERVQUAL.

This study presents empirical evidence of the benefit of viewing narrative video clips on embedded virtual reality (VR) websites of hotels to relieve travel anxiety. As the effectiveness of using VR functions to relieve travel anxiety has been shown, we proposed that a VR website enhanced with narrative video clips could relieve travelers' anxiety about accommodations by showing the important aspects of a hotel. Thus, we created a website with a narrative video showing the escape route from a ho

When users begin to feel uncomfortable about the influence of social network services (SNSs) on their lives, they react with various discontinuance behaviors. This comparative study intends to provide a comprehensive explanation of how the fatigue or regret phenomenon is related to users’ diverse reactions against SNSs. This study attempts to answer two questions: (1) How do specific types of relationships influence social overload from SNS interactions on Facebook? and (2) How does social overl

This study aims to analyze whether technological changes in the fourth industrial revolution (4IR), as independent variables, can influence employment, a dependent variable. It categorizes scientific technology changes in the 4IR based on related research, and identifies six factors and corresponding research hypotheses. The paths for the six hypotheses were analyzed using 275 effective samples. Results show that life-convenience technology and blockchain technology variables significantly influ

Twelve sampling locations in a network from a water treatment plant to consumers' taps were selected for measuring residual chlorine loss, THMs, TOC, etc. and 24 hour sampling in the locations was conducted on a bimonthly basis for one year. Chlorine bulk decay and THM formation tests were carried out by bottle tests under controlled temperatures for three locations: a water treatment plant, a large service reservoir, and a pumping station. Water quality modelling of chlorine loss in the distrib

This study discusses the employability of the workforce in relation to information communication technology. There is a difference in understanding in terms of items of importance/satisfaction during/after employment processes when considering organizations related to the information technology workforce. An empirical analysis of Korean employability based on literature from Asia was conducted. It indicated that differences in the perception of the 12 items comprising importance and satisfaction

최근 스마트폰 스파이웨어는 PC의 여러 가지 유형의 바이러스 요소들을 닮아가고 있으며, 점점 심각해지고 있는 추세이다. 또한 스마트폰 스파이웨어의 성장속도에 비해 스마트폰의 보안과 관련된 측면들은 매우 취약한 상태이지만 사용자들은 그러한 위험 요소들을 심각하게 인지하지 못하고 있는 실정이다. 이에 본 연구는 개인적 성향과 스파이웨어에 대한 인식을 바탕으로 정보보안이 스마트폰 선택에 미치는 영향을 살펴본다. 연구 모델의 주요 변수는 독립 변수로 개인별 위험성 감수정도와 스마트폰 스파이웨어 위험성을 선정하고, 종속 변수로 스마트폰 구매 의향을 설정하였다. 현재 스마트폰을 사용하고 있는 사용자를 대상으로 설문조사를 통해 얻은 200부의 유효한 자료를 SPSS 21 통계 프로그램을 이용하여 검증하였다. 연구결과에 의하면 개인별 위험성 감수정도에 따라 스마트폰 스파이웨어의 위험성을 인지하는 것과, 스마트폰 스파이웨어의 위험성을 인지할수록 스마트폰 구매의향에 영향을 미치는 것으로 나타났다. 즉

Today, IT governance has also become a subject of attention along with recent technologies such as ITSM (IT Service Management), PPM (Project Portfolio Management) and Compliance. At the national level, the market is fairly recent, and therefore, lacks detailed research in the field. Models specifically related to EIM has not yet been presented to this day, hence, firms that are considering EIM as a potential part of their information management system may fall into a state of disorder in the pr

최근 의사에게 진단을 받았음에도 불구하고 다른 의사를 방문하여 견해를 듣고자 하는 환자의 경향인 의사선택(doctor shopping)이 증가하고 있다. 본 연구의 목적은 인터넷 정보에 대한 사람들의 인식을 조사하고 닥터쇼핑에 영향을 주는 변수가 무엇인지 실증분석을 통해 제시하는 것이다. 2009년 10월 16일부터 11월 6일까지 설문조사를 실시하여 질병 치료를 위해 의료서비스를 이용한 223명의 유효 데이터를 수집했다. 연구결과 닥터쇼핑에 영향을 주는 변수는 의사의 치료에 대한 신뢰와 인터넷 정보에 대한 신뢰인 것으로 나타났다. 소비자로서의 환자는 자신이 가지고 있는 정보를 기반으로 상품을 쇼핑하듯 의료서비스를 선택하며 인터넷은 닥터쇼핑 행동의 촉매제 역할을 일부 하고 있는 것으로 파악되었다.
