  • Objectives: Small enterprises have higher exposure to occupational hazards compared to larger enterprises and further, they have fewer resources to control the risks. In order to improve the working environment, development of efficient measures is therefore a major challenge for regulators and other stakeholders. The aim of this paper is to develop a systematic model for the design of tailored intervention programmes meeting the needs of small enterprises. Methods: An important challenge for the design process is the transfer of knowledge from one context to another. The concept of realist analysis can provide insight into mechanisms by which intervention knowledge can be transferred from one context to another. We use this theoretical approach to develop a design model. Results: The model consist of five steps: 1) Defining occupational health and safety challenges of the target group, 2) selecting methods to improve the working environment, 3) developing theories about mechanisms which motivate the target group, 4) analysing the specific context of the target group for small enterprise programmes including owner-management role, social relations, and the perception of the working environment, and 5) designing the intervention based on the preceding steps. We demonstrate how the design model can be applied in practice by the development of an intervention programme for small enterprises in the construction industry. Conclusion: The model provides a useful tool for a systematic design process. The model makes it transparent for both researchers and practitioners as to how existing knowledge can be used in the design of new intervention programmes.

  • Non-Functional Requirements (NFR) play a crucial role during the software development process. Currently, NFRs are considered more important than Functional Requirements and can determine the success of a software system. NFRs can be very complicated to understand due to their subjective manner and especially their conflicting nature. Self-adaptive systems (SAS) are operating in dynamically changing environment. Furthermore, the configuration of the SAS systems is dynamically changing according to the current systems context. This means that the configuration that manages the trade-off between NFRs in this context may not be suitable in another. This is because the NFRs satisfaction is based on a per-context basis. Therefore, one context configuration to satisfy one NFR may produce a conflict with another NFR. Furthermore, current approaches managing Non-Functional Requirements trade-off stops managing them during the system runtime which of concern. To solve this, we propose fragmentizing the NFRs and their alternative solutions in form of Multi-entity Bayesian network fragments. Consequently, when changes occur, our system creates a situation specific Bayesian network to measure the impact of the system's conditions and environmental changes on the NFRs satisfaction. Moreover, it dynamically decides which alternative solution is suitable for the current situation.

  • Are intentions important in deciding the outcome of an action such as sharing misinformation among social media users during the pandemic? What is their role and how far they are important for the very act of fake sharing news? The social media users' actions on the social platform are determined by what they plan to do themselves; however, their motivation has an immense role to play in the dissemination of fake news on social media. The study proposes a conceptual model for understanding how select factors affect fake news sharing motivation and intentions of social media users. The study scrutinizes the relationship between content and context, fear of missing out (FoMO), news verification and news sharing gratification on the motivation and intention of social media users of networked Asian society. Empirical Data were drawn from social media users (N = 243) from India, using an online questionnaire based on prior studies and structural equation modeling (SEM) approach was used to analyze the data collected. Results indicate that news content, news verification, and news sharing gratification have a direct and positive relationship with sharing motivation. On the other hand, news context and content, FoMO and news sharing gratification have a positive significant relationship with sharing intention. Likewise, it was discovered that news verification will decrease sharing intention of the social media users. However, news context, that is the pandemic in the case of the present study and FoMO were not identified as determinant variables for sharing motivation among social media users. The research limitations and further scope were discussed.

  • An essential prerequisite for negotiating governance of 'internet,' a world of 'end to end' nature, is to guarantee end-users' participation. Internet Governance Forum (IGF), the outcome of World Summit on the Information Society(WSIS) Tunis Agenda, has played an important role as a representative mulitistakeholder - based governance model, which puts emphasis on wide range participation of stakeholders. Notwithstanding multistakeholderism materialized in IGF has been challenged, IGF itself is a unique place for participation to broad internet governance discourse, as all voices get hearing grounded on openness, inclusion, and transparency, quite distinct from the multilateral negotiation based model such as 'Conference on Cyberspace.' Therefore civil society which represents end-users' interest, as a crucial stakeholder of internet governance, should establish more strategic and coordinated approach to IGF itself as well as reformation discourse of internet governance. In this regard, civil society groups of Korea, began with hosting workshops and Open Forum at the 2013 IGF in Bali, Indonesia. This report also describes the detailed activities of Korean civil society group in 2013 IGF.

  • 모바일 환경으로 업무 환경이 변화함에 따라 발생할 수 있는 요구사항인 탈 사무실화, 기기의 다양성, 실시간성을 만족하면서 보안성을 유지하기 위해 context aware RBAC 모델이 적용되고 있다. 하지만 기존의 상황인식 역할기반 접근제어 모델은 주변 사용자에 대한 고려가 없고 사용자의 단독적인 정보 유출이 가능하다는 단점을 가지고 있다. 이를 해결하기 위해 본 연구에서 제안하고 있는 사용자간의 관계를 고려한 상황인식 역할기반 접근제어 모델에서는 기존의 기법에서 고려하지 않은 주변 사용자의 역할 및 관련된 사용자와의 관계를 고려하여 위치와 시간만으로 제어되지 않는 정보에 대한 유출을 방지한다. 이 모델을 적용할 경우 주변사용자의 권한에 의해 사용자의 권한이 통제되므로 문서에 대한 내부자의 편법적인 사용을 방지하는 것이 가능하고 실시간으로 문서에 대한 권한을 부여할 수 있다. 또한 문서에 대한 권한을 모두 부여할 경우와 동일한 업무 효율성을 가지면서 필요하지 않은 시간에 발생할 수 있는 보안 위협을 방지할 수 있다.

  • With the progress of information technology and the rapid development of the gamification marketing, corporate marketing through virtual CSR co-create as customer acquisition, customer retention strategy has become the hot topic, but the reality results show that the effect of virtual CSR co-create fails to reach an enterprise's marketing purposes. Based on the success model of D&M information system, from the perspective of customer engagement, this study analyzes how enterprises achieve customer engagement and bring gameful experience to customers through gamification marketing in the context of virtual CSR co-create. The empirical results show that the quality of game information -- social interaction and sense of achievement in the context of virtual CSR co-create have a significant positive impact on consumers' gameful experience, and customer engagement plays a partial mediating role between social interaction, sense of achievement and consumers' gameful experience.

  • To provide a fundamental understanding on the inherent relationship between IT capabilities and sustainable firm heterogeneity, we investigate the dual roles that institutional pressures play, namely, as antecedents of IT capabilities and as moderator of the relationship between IT capabilities and IT innovation success, where IT innovation success plays a mediating role between IT capabilities and firm performance. The structural model was tested, and the results of the PLS analysis provided general support for the proposed hypotheses. IT capabilities had an indirect effect mediated by IT innovation success on firm performance. With IT activities assumed to be embedded in the institutional context, the dual roles of institutional pressures are verified. This study contributes to the literature on IT capabilities by considering both the determining role of institutional pressures on IT capabilities and the institutional context of the chain that connects IT capabilities to firm performance. The results suggest that a firm not only manages various institutional pressures to foster its IT capabilities but also adapts to different contexts with a certain level of institutional pressures to facilitate its IT capabilities and outperform its competitors, which could be sustained through IT innovation success.

  • The building production system has been analysed by the dichotomy "employer-contractor" relationship, which failed to take into account of the role and function of multiple stakeholders within the life-cycle supply chain. This is further observed in the current conflict resolution model, which, in my argument, struggles to contribute to industrialize the building production and achieve better efficiency and effectiveness as expected. The purpose of this paper is to critically assess the issues of current programme-based conflict resolution model, and discuss alternative models how they can be modelled and applied to the construction projects. The conclusions of findings are; First, the current model is framed around the contracts and dispute resolutions based on the legal concept of "claimant and respondent" where one party(s) advances a claim once and the other(s) objects, as such it fails to reflect the nature of construction projects where multiple stakeholders are involved concurrently and for a long period of life-cycle of buildings. Second, an alternative is "Six-stakeholders model" which represents the multiple stakeholders and clarifies the flow of obligation-liability-monetary relationships among participants for a long period of life-cycle of buildings. Further, with reference to both historical and recent cases, a reflection and insight into pros and cons of programming method is added, especially as to why this method is considered to have become a mandate of the modern construction management, and how academics and practitioners should deal with it more cautiously and prudently.

  • Human Emotion Recognition is an exciting topic that has been attracting many researchers for a lengthy time. In recent years, there has been an increasing interest in exploiting contextual information on emotion recognition. Some previous explorations in psychology show that emotional perception is impacted by facial expressions, as well as contextual information from the scene, such as human activities, interactions, and body poses. Those explorations initialize a trend in computer vision in exploring the critical role of contexts, by considering them as modalities to infer predicted emotion along with facial expressions. However, the contextual information has not been fully exploited. The scene emotion created by the surrounding environment, can shape how people perceive emotion. Besides, additive fusion in multimodal training fashion is not practical, because the contributions of each modality are not equal to the final prediction. The purpose of this paper was to contribute to this growing area of research, by exploring the effectiveness of the emotional scene gist in the input image, to infer the emotional state of the primary target. The emotional scene gist includes emotion, emotional feelings, and actions or events that directly trigger emotional reactions in the input image. We also present an attention-based fusion network, to combine multimodal features based on their impacts on the target emotional state. We demonstrate the effectiveness of the method, through a significant improvement on the EMOTIC dataset.

  • Increasing competitive pressure, the constantly accelerating transformation of the economy, and a stronger focus on value creation have initiated the search for sustainable sources of competitive advantage in organizations. In this context, the concept of treating organizational knowledge as a valuable strategic resource has become quite popular recently. Knowledge has become the most critical component in the struggle for sustained competitive advantage and knowledge management (KM) has also been described for its possible role in creating sustainable competitive advantage. In order to examine the contingency between KM resources, KM strategies, and KM performance of organizations, a contingency model of KM, which is based on resource-based theory as well as knowledge-based theory, is developed from the information systems and strategic management literature in order to assess the following questions: (i) What KM resources affect the organization's KM strategies? (ii) Is there a relationship between KM strategies and organizational performance enhanced by KM? A detailed exploratory analysis of survey responses from 79 Korean companies provides the following significant findings: (i) This study found support for the proposed contingency model of KM; (ii) The organization's KM strategies are determined by social resources and its capabilities; (iii) An organization with a culture-based KM strategy is more likely to enhance organizational KM performance than an organization with a technology-based KM strategy.
