Multi-agent systems have been developed for supporting intelligent collaboration of distributed and independent software entities and are be-ing widely used for various applications. For the collaboration among agents, conversation policies (or interaction protocols) mutually agreed by agents are used. In today's dynamic electronic market environment, there can be frequent changes in conversation policies induced by the changes in transaction methods in the market, and thus, the importance of ad hoc conversation policies is increasing. In existing agent platforms, they allow the use of only several standard or fixed conversation policies, which requires inevitable re implementation for ad hoc conversation policies and leads to inefficiency and intricacy. This paper designs an agent platform that supports ad hoc conversation policies and presents the prototype implementation. The suggested system includes an exchangeable and interpretable conversation policy model, a meta conversation procedure for exchanging new conversation policies, and a mechanism for performing actual transactions with exchanged conversation policies in run time in an adaptive way.

Architectural & Interior design communication is a process of exchanging information between architects and other professionals, clients, and prospectus users, and a design medium is a means of communication. Using non-immersive, conventional media, it is challenging for architects communicate physical details and users' activities in not yet built three-dimensional buildings to others. Recent advances online, Multi-User Virtual Environments (MUVEs) allow architects and other professionals to experience a virtually constructed building together using anthropomorphic avatars. In addition, MUVEs also enable them to be aware of the presence and activity of each other. Previous studies suggest that the aforementioned characteristics of MUVEs may facilitate communication between architects and others. But these are focused on communication in controlled experimental conditions. This paper discusses the ways in which MUVEs are applied for authentic and long-term collaboration, design studio, and cultural heritage reconstruction projects, produced by digital design group at the UC Berkeley and the Technion-Israel Institute of Technology, and analyzes the influences of MUVEs on those projects. MUVEs helped more precise communication between architects, electronic engineers, and medical staffs, who are collaborating for developing pioneering technology for hospitals. In design studios, MUVEs allowed students to experience other students' design outputs, and thus helped them share ideas mutually. In addition, in cultural heritage reconstruction projects, MUVEs were used for communicating with historians and residents in order to collect evidence. Based on this study, we propose that MUVEs have strong potential for enhancing the communication between architects and other professionals.

Though the rate of incidence of each rare disease, including mucopolysaccharidosis (MPS), is low, this is not the case if they are taken as a whole. Rare diseases often have genetic causes and vary in type. However, the signs and symptoms vary greatly by disease, making it difficult to make accurate diagnoses and conduct necessary research, which is why we believe it is a field that deserves more attention and research. It is important to establish an infrastructure of experts in each country and promote cooperation within the Asia-Pacific region in order to improve specialist training and communication. Given the need for a system of cooperation, the Asia Pacific MPS Network (APMN) was established by several MPS experts in South Korea, Japan, and Taiwan in January 2013. Thereafter, the Asia Pacific MPS Registry (APMR), an electronic remote data system, was established by the APMN. Then, the Association for Research of MPS & Rare Diseases (ARMRD), an academic society that supports research on MPS and other rare diseases, was established by President Dong-Kyu Jin in April in 2015. The main task of the ARMRD is to support APMN-related work. The ARMRD published a uniform guideline that reflects the characteristics and circumstances of local patients through the Korean MPS Expert Council. Now, the APMN, APMR, and the annual Korean MPS Symposium are supported by ARMRD. Organizations like the APMN and APMR are necessary because international cooperation and collaboration are needed to conduct clinical trials on those diseases. ARMRD members hope to encourage the interest of experts and researchers of MPS & rare diseases as well as active participation in the research and treatment of patients suffering from rare diseases, including MPS, to ultimately improve the quality of life of the patients as well as their families.

With the deregulation of electronic finance, FinTech has been revitalized. The discussion on artificial intelligence is active in the financial industry. However, there is a problem of increasing security threats behind new technologies. Security vulnerabilities have increased because we are more connected than before, and the channels and entities of the financial industry have diversified. Although there are technical and policy discussions on security, the essence of all discussions is human. Fundamentals of finance are trust and security, and attention to human factors is important. This study presents the role of human and artificial intelligence for financial security, respectively. Furthermore, this derives a collaborative model in which human and artificial intelligence complement each other's limitations. To support this, it first discusses the development of finance and IT, AI, human factors, and financial security threats. This study suggests that the security threats will intensify in the era of new technology, but it can overcome them by using machinery and technology.

With the advent of communication technologies including electronic collaborative tools and conferencing systems provided over the Internet, virtual collaboration is becoming increasingly common in organizations. Virtual collaboration refers to an environment in which the people working together are interdependent in their tasks, share responsibility for outcomes, are geographically dispersed, and rely on mediated rather than face-to face, communication to produce an outcome. Research suggests that new sets of individual skill, knowledge, and ability (SKAs) are required to perform effectively in today's virtualized workplace, which is labeled as individual virtual competence. It is also argued that use of online social networking sites may influence not only individuals' daily lives but also their capability to manage their work-related relationships in organizations, which in turn leads to better performance. The existing research regarding (1) the relationship between virtual competence and task performance and (2) the relationship between online networking and task performance has been conducted based on different theoretical perspectives so that little is known about how online social networking and virtual competence interplay to predict individuals' task performance. To fill this gap, this study raises the following research questions: (1) What is the individual virtual competence required for better adjustment to the virtual collaboration environment? (2) How does online networking via diverse social network service sites influence individuals' task performance in organizations? (3) How do the joint effects of individual virtual competence and online networking influence task performance? To address these research questions, we first draw on the prior literature and derive four dimensions of individual virtual competence that are related with an individual's self-concept, knowledge and ability. Computer self-efficacy is defined as the extent to which an individual beliefs in his or her ability to use computer technology broadly. Remotework self-efficacy is defined as the extent to which an individual beliefs in his or her ability to work and perform joint tasks with others in virtual settings. Virtual media skill is defined as the degree of confidence of individuals to function in their work role without face-to-face interactions. Virtual social skill is an individual's skill level in using technologies to communicate in virtual settings to their full potential. It should be noted that the concept of virtual social skill is different from the self-efficacy and captures an individual's cognition-based ability to build social relationships with others in virtual settings. Next, we discuss how online networking influences both individual virtual competence and task performance based on the social network theory and the social learning theory. We argue that online networking may enhance individuals' capability in expanding their social networks with low costs. We also argue that online networking may enable individuals to learn the necessary skills regarding how they use technological functions, communicate with others, and share information and make social relations using the technical functions provided by electronic media, consequently increasing individual virtual competence. To examine the relationships among online networking, virtual competence, and task performance, we developed research models (the mediation, interaction, and additive models, respectively) by integrating the social network theory and the social learning theory. Using data from 112 employees of a virtualized company, we tested the proposed research models. The results of analysis partly support the mediation model in that online social networking positively influences individuals' computer self-efficacy, virtual social skill, and virtual media skill, which are key predictors of individuals' task performance. Furthermore, the results of the analysis partly support the interaction model in that the level of remotework self-efficacy moderates the relationship between online social networking and task performance. The results paint a picture of people adjusting to virtual collaboration that constrains and enables their task performance. This study contributes to research and practice. First, we suggest a shift of research focus to the individual level when examining virtual phenomena and theorize that online social networking can enhance individual virtual competence in some aspects. Second, we replicate and advance the prior competence literature by linking each component of virtual competence and objective task performance. The results of this study provide useful insights into how human resource responsibilities assess employees' weakness and strength when they organize virtualized groups or projects. Furthermore, it provides managers with insights into the kinds of development or training programs that they can engage in with their employees to advance their ability to undertake virtual work.
