Smarthome is one of the remarkable fields of the industrial revolution 4.0, which are popular in many countries such USA, EURO, Japan and Korea. However, how Vietnamese people are considering and having intension to use smarthome devices is still a question for marketers and researchers. This study develops a comprehensive research model that can explain potential customers' behavioral intentions to adopt and use Smarthome services in Viet Nam and figure which key factors affect the intention. This study proposes and validates a new theoretical model that extends the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2). The model consists of eight factors that affect one element (Behavioral Intention), specifically: Habits, Perceived usefulness, Perceived ease of use, Trust, Innovativeness Personal, Perceived value, Hedonic motivations and Social influences. Data were collected from 304 Vietnamese citizens by sending the email to survey questionnaire, direct contact with the experienced smarthome users. Through regression analysis, data from samples were analysed with SPSS 20 software and verification of hypotheses, the results show the key determinants affecting the intention to use smarthome appliances in Vietnam: Perceived Value, Social Influence, Perceived Usefulness, Perceived Ease of Use and Trust. From this result, several recommendations have been suggested to to smarthome devices vendors and marketer to improve products as well as marketing approaches to meet customer needs.

스마트워치의 확산이 예상과는 달리 더디게 진행되고 있다. 스마트워치 공급업체들은 현재의 캐즘을 극복하기 위해 새로운 전략을 수립할 필요가 있다. 그러나 스마트워치의 어떠한 속성을 전략적으로 활용하여 시장 확산을 이루어야 하는가를 타당하게 수행한 연구는 매우 드물다. 본 연구는 스마트워치가 가져다줄 것으로 예상되는 혜택과 이를 위해 치러야 할 비용을 소비자 관점에서 분석하고, 소비자의 혁신성향이 시장 확산에 기여할 수 있는지를 살펴보았다. 이를 위해 323개의 유효데이터를 확보하여 구조 방정식 분석을 실시하였다. 분석 결과, 스마트워치의 두 가지 혜택(utilitarian and hedonic)과 세 가지 비용(usability, performance, and finance)이 가치인식을 통해 사용의도에 영향을 주는 것으로 나타났다. 또한 소비자의 혁신성향이 가치인식과 사용의도의 관계를 조절하는 것으로 드러났다. 주목할 점은, 소비자들이 스마트워치가 사회적 혜택을 가져다 줄 것으로 기대할 것이라는 가설이 기각되었다는 점이다. 즉, 스마트워치 사용이 소비자에게 이미지 향상을 가져다 줄 것이라는 전략은 스마트워치 확산에 큰 기여를 하지 않을 수 있다. 스마트워치의 시장 확산을 이루기 위해서는 혁신성향이 높은 소비자들을 대상으로 소비자들이 기대하는 혜택을 활용하는 전략을 수립해야 한다.

Infringement of information security has caused the corporate image to be damaged and share price to fall, and it is emerging as an organizational risk. The value of information assets in enterprises has led to a higher level of security than in the past. As a result, companies are aware of the need for officers to protect information and to oversee a security management system. However, despite the growing importance of information security officers, there is a lack of research on their roles and characteristics. This study validates the relationship between determinants that affect the performance of information security. And a structural equation model was presented and empirically analyzed to see the impact of the internal and external characteristics of the staff in charge of information security on the organization's information security performance.

The mobile Internet (M-Internet) service is a form of subscription-based information Systems (IS) services in which usage continuance is essential for the eventual success of the service providers. However, previous research on IS continuance has focused mainly on the technology user aspects despite the fact that the user plays a dual role of being a technology user and service consumer in many IS usage contexts. This study thus aims to examine IS continuance based on the theoretical foundation of dedication-based and constraint-based customer relationship development in the context of M-Internet service. Four customer relationship development factors (satisfaction, perceived value, familiarity, and switching costs) are identified and tested on how they affect continuance intention from a survey conducted on M-Internet service users. Then, the results of this study are discussed along with its limitations and implications.

The drastic structural changes in telecommunications industry are imposing new strains on operators, regulators and customers. Many researchers have offered diverse frameworks for the changes from the perspectives of sociology, technology, and/or economics. However, there have been few attempts to document the competitive phenomena from management perspectives because of the technological complexities and dynamism in the fundamental transition of competition. In this study, we examine competitive environment in telecommunications industry, and identified five structural elements; telecom operator, competitors, regulation, suppliers, and customer demand. The suggested framework is used to provide a basis for explaining the changes in the characteristics of individual elements and the interactions among them. The dynamic industry-specific changes will be explained through an evolutionary model. We specify the characteristics of progressive stages and the determinants of the evolution. Changes are reviewed in terms of five criteria; regulations and competitions, value chain, technology, customers demand, and internal operations. The result of this study will be useful in analyzing and predicting industry structure and major participants' strategic behaviors and decision patterns. This study can alse be extended to other industries facing dynamic structural changes.

The adoption of technology has always been of interest to academicians and practitioners of the field of Management Information System. This is so because without proper and adequate adoption, technology-no matter how beneficial or advanced it may be-will be of little value to users. Numerous researches, such as the researches of the Technology Acceptance Model (TAM) or the Unified Theory of Acceptance and Use of Technology (UTAUT), had been conducted to understand the human nature in association with the adoption or rejection of technologies that have bombarded the users. The coming of smart technologies (i.e., smart phones and devices), however, seems to have fundamentally changed the environment for adoption. The ubiquity combined with mobility of technology, especially when it comes to mobile apps, seem to make the old PC era of two-stage-pre and post-adoption models obsolete. A new model of adoption that identifies the determinants of technology acceptance and continuance is needed for the smart age. To this end, this paper undertakes an empirical study, by analyzing 229 users of Social Networking Service (SNS) mobile apps, to identify the role of user experience on the multi-stage adoption of technology, and provides results that User Experience (UX) plays the crucial role of bridging the separate stages of pre and post adoption of technologies. The paper concludes by providing practical implications of the new model as it relates to mobile apps and technologies, and recommendations for further studies to get a better understanding of technology adoption in the smart age.

As knowledge-based society comes to the fore, sharing knowledge becomes a hot issue. Among various types of knowledge, a significance of software(applications) and contents is a huge in a current society. Moreover, along with appearance of smartphone, for instance iPhone, Application Store(also known as AppStore) utilized as a common gateway for sharing software and contents, brings a big interest for many users and developers. However, prior research to understand users' behavior on AppStore has been a scant. Therefore, the main purpose of this study is to investigate the impact of key smart service environmental factors on AppStore in order to empirically explain users' psychological feelings of intention to use AppStore. Based on a well-known technology adoption model, TAM, the study incorporates three main characteristics(user, society, and service) with six constructs(Innovation, Enjoyment, Subjective Norm, Information Level, Content variety, and Cost), influencing perceived usefulness, which then affects users' intention to use AppStore. Results provide evidence that support the tested hypotheses. The implications of the findings suggest a new theoretical work for future AppStore research and offers suggestions that the researchers and practitioners of AppStore should consider regarding the development of application and contents.

The main attractant of portable multimedia player(PMP), is often their versatility : being able to load and play different formats of video, audio, digital images, and interactive media. In this paper, we investigate the factors influencing the usage the PMP, based on the extended version of the Technology Acceptance Model. Using the data collected from online survey, we show that perceived usefulness, perceived ease of use, and perceived enjoyment are the major determinants for using PMP. Factors, including ubiquitousness, community, and image are shown to directly or indirectly determine the level of perceived usefulness and ease of uses. In addition, we classify PMP users into two groups, users seeking hedonic value and utilitarian value, and examine the differences in path coefficients. Properties of the causal paths, including standardized path coefficients, the significance of difference, in the hypothesized model, are also presented, so that we can investigate the relative influences of different dominants, demonstrating how two groups differ in their decision-making processes regarding the PMP usage.

임팩트 투자는 사회적 가치와 재무적 이익을 동시에 추구하는 소셜벤처에 대한 투자로, 재무적 수익을 창출하는 동시에 다양한 사회문제를 혁신적으로 해결하는 데 중점을 둔다. 국내 임팩트 투자 생태계는 정부 및 공공기관의 주도 하에 성장하였으며, 2021년 운용자산 기준 총 7,000억원으로 3년만에 3.5배 증가하였다. 이러한 양적 성장과 함께 질적 성장을 견인하기 위하여 벤처투자와 구분되는 임팩트 투자에 대한 연구가 필요한 시점이다. 이에 본 연구는 임팩트 투자만의 차별화되는 영향요인을 실증 분석하는 것을 목적으로 하였다. 먼저 선행연구 고찰을 통해 투자 결정에 영향을 미치는 요인을 확인하고 임팩트 투자사 대표 및 심사역 11명을 대상으로 델파이 조사를 수행하여 주요 요인을 도출하였다. 이후 임팩트 투자 심사역 10명을 대상으로 AHP 조사를 실시하여 중요도 우선순위를 확인하였다. 상위 요인의 중요도는 시장>창업가(팀)>제품·서비스>재무의 순서로 높게 나타났으며, 세부요인의 중요도는 '시장의 경쟁강도 및 진입장벽>신시장 창출 가능성>시장성장 및 확장 가능성>팀의 전문성 및 역량>제품·서비스의 차별성 및 경쟁력'의 순서로 나타났다. 연구 결과, 선행연구에서 밝힌 벤처투자 결정요인과 다르게 임팩트 투자는 시장 관련 요인을 중요하게 평가하고 특히 투자 결정 시점에서 소셜벤처의 사회적 가치 보다 비즈니스 모델의 지속가능성과 수익을 중요하게 고려한다는 점을 확인하였다.

To achieve the widespread use of Mobility as a Service (MaaS), a novel transportation platform, it is important to increase consumers' intention to use MaaS. Therefore, this study clarifies the determinants of consumers' intention to use MaaS based on the UTAUT2 model. The research model is tested using structural equation modeling based on data from a web-based questionnaire survey of Japanese consumers. The results show that performance expectancy, social influence, hedonic motivation, and price value have significant effects on the intention to use MaaS. Moreover, the relationship between the intention to use MaaS and independent variables is moderated by old age. Theoretical and practical implications are discussed based on the findings.
