Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.

Regarding urban design in this 21st century, cities pursue human-oriented urban design through which nature, cities, and human beings are unified and interact with one another. For such urban design maintenance, it is needed to conduct systematic analysis and synthesis on various and complex factors of cities expressing urban images. Also, it is necessary to secure methods to evaluate those cities based on urban users' visual information. Thereupon, this study aims to suggest urban design evaluation methods which accept human behavior or needs and also allow us to figure out desirable images. For this, the study established the construction system of the most basic urban design components that form cities through literature review and expert evaluation. And it examines correlation among those factors with statistic means. Through this, the study suggests a new urban design evaluation system and evaluation process divided into experts and users so as to reflect user behavior or needs.

In this paper, the difficulties involved in analyzing and designing a management system for product development are discussed with reference to reducing the impact of products on the environment. We propose some models and methods to analyze information behavior in the process of product development based on a fusion model which integrates the assessments of users’ needs, the environment, and available technology. These models and methods are subsequently applied to the development of a new packaging material. The results of this case study allow us to identify effective information for the design of a management system for product development to reduce the impact of products on the environment.

The low use of e-vehicles in Yogyakarta City and Pekanbaru City is an essential issue for local governments to maximize e-government policies in both regions. The purpose of this research is to analyze people's attitudes and factors influencing the community of e-Samsat (e-Vehicle tax) users in developing the UMEGA theory, namely technology and government trust. This is a quantitative research based on the philosophy of positivism, which is used to examine populations and individual samples. Data were collected using research instruments and quantitatively analyzed. Furthermore, the hypothesis of the obtained data was tested using SEM-PLS. The results showed that social influence does not affect attitudes of e-Samsat (e-Vehicle tax) users. Furthermore, the study showed that the development of umega theory by adding variables of trust in technology and government affects people's behavior in using e-Samsat services.

Today, news avoidance has become an inevitable trend, particularly exacerbated since the outbreak of the COVID-19 pandemic in 2020. To delve deeper into the shifting tendencies of news consumers towards news avoidance and unveil the motivations behind this avoidance, this study recruited 500 Chinese news consumers aged between 20 and 60 years old, employing survey questionnaires as the research method. Through an indepth examination of their news consumption behavior at different stages of the COVID-19 pandemic, we discovered that individuals' risk perceptions and efficacy beliefs significantly influence their patterns of news consumption. Furthermore, we identified negative emotions, information overload, and media distrust as the primary reasons for news avoidance among Chinese news consumers during the COVID-19 crisis. These findings Not only provide crucial insights into understanding the dynamics of news consumption behavior but also offer valuable reference points for the news industry to better fulfill its role and value during crises in the future.

클라우드 서비스의 등장과 진화는 정보통신기술 발전에 기여한 가장 큰 잠재력을 가진 기술 중에 하나이다. 클라우드 서비스의 잠재력을 발휘하기 위해서는 서비스 제공자와 소비자관점에서 다양한 이슈들에 대한 명확한 정의와 이해가 필요하다. 클라우드 서비스에 대한 기존의 논의는 주로 사업자의 입장에서 클라우드 비즈니스 모델의 발굴, 수익 모델의 발굴, 기술 발전에 따른 전망 등에 초점을 맞추어져 왔고 정작 서비스 이용자는 상대적으로 낮은 관심을 받아온 것이 사실이다. 본 논문에서는 클라우드 서비스 중 SaaS 서비스의 이용자 측면에서 서비스 이용행태를 분석하고 이를 기반으로 향후 SaaS 서비스의 발전 전략에 대하여 논의하고자 한다. 이를 위해 SaaS 서비스 이용자를 현재 서비스를 이용하고 있는 이용자군과 현재에는 SaaS 서비스를 이용하지는 않지만 향후에는 서비스를 이용할 의도를 가지고 있는 잠재 이용자군으로 구분하여 설문조사를 수행한 설문결과를 토대로 이용자의 이용행태를 분석하였다. 궁극적으로 본 연구에서는 이용자의 행태분석 결과 기반의 SaaS 서비스의 발전 전망, 발전 전략 및 정책과제를 제시하였다.

The functional behavior of a portable consumer electronic (PCE) product is nearly all expressed with human-machine interaction (HMI) tasks. Although physical prototyping and computer aided design (CAD) software can show the appearance of the product, they cannot properly reflect its functional behavior. In this paper, we propose a virtual prototyping (VP) system that incorporates virtual reality and HMI functional simulation in order to enables users to capture not only the realistic look of a PCE product but also its functional behavior. We obtain geometric part models of the product and their assembly and kinematics information with the help of CAD and reverse engineering tools, and visualize them with various display tools. We adopt state transition methodology to capture the HMI functional behavior of the product into a state transition chart, which is later used to construct a finite state machine (FSM) for the functional simulation of the product. The FSM plays an important role to control the transition between states of the product. The proposed VP system receives input events such as mouse clicks on buttons and switches of the virtual prototype model, and it reacts to the events based on the FSM by activating associated activities. The VP system provides the realistic visualization of the product and the vivid simulation of its functional behavior. It can easily allow users to perform functional evaluation and usability testing. Moreover, it can greatly reduce communication errors occurring in a typical product development process. A case study about VP of an MP3 player is given to show the usefulness of the proposed VP system.

This research aimed (1) to study and analyze the ability of current information retrieval (IR) systems based on views of information behavior (IB), and (2) to propose a conceptual framework for an IB model based on the collaboration between the system and user, with the intent of developing an IR system that can apply intelligent techniques to enhance system efficiency. The methods in this study consisted of (1) document analysis which included studying the characteristics and efficiencies of the current IR systems and studying the IB models in the digital environment, and (2) implementation of the Delphi technique through an indepth interview method with experts. The research results were presented in three main parts. First, the IB model was categorized into eight stages, different from traditional IB, in the digital environment, which can correspond to all behaviors and be applied to with an IR system. Second, insufficient functions and log file storage hinder the system from effectively understanding and accommodating user behavior in the digital environment. Last, the proposed conceptual framework illustrated that there are stages that can add intelligent techniques to the IR system based on the collaboration perspective between the user and system to boost the users' cognitive ability and make the IR system more user-friendly. Importantly, the conceptual framework for the IB model based on the collaboration perspective between the user and system for IR assisted the ability of information systems to learn, recognize, and comprehend human IB according to individual characteristics, leading to enhancement of interaction between the system and users.
