A study on the global trend of accreditation for mediators implies many important aspects of controlling of the quality of mediation. Firstly, whether or not having an accreditation system, most European countries and the U.S. have a common understanding on the fact that mediators need to be trained to mediate disputes, apart from their own expertise on the subject matters. Secondly, private-led accreditation has been utilized in countries having a Anglo-American law system such as the United Kingdom and the U.S. a while nation-managed one has been operated in the countries having a continental law system such as Austria, Belgium, Italy and Germany. Thirdly, private mediation service providers (usually institutions or companies) play an active role in the training and accreditation of mediators and further make them act as mediators in the disputes referred to them. Fourthly, the countries having a nation-managed accreditation system usually stipulate a certain mediation training and accreditation requirement by law. Fifthly, there is no uniform trend on the minimum hours of training required for accrediting the mediators. Sixthly, mediation training generally focuses on the practical mediation capacity-building, including mediation theory and role-playing, mediation simulations, peer review and supervision. And finally, the mediation theory mainly includes the role of mediator, mediation procedures, mediation communication, negotiation and communication skills, mediation ethics and mediator's code of conduct, etc.

The purpose of this study was to investigate the effect of parental attachment on the subjective well-being of undergraduate students and the role of perfectionism. Undergraduate students(N=416) were administered a questionnaire on parent and peer attachment, and the results were characterized by the well-being scale, and multidimensional perfectionism scale. The results indicated that trust had a positive effect on life satisfaction, whereas isolation had a negative effect on life satisfaction. Parental communication had a positive effect on self-oriented perfectionism and socially prescribed perfectionism. Self-orientated perfectionism and socially prescribed perfectionism had a positive effect on positive affection and life satisfaction and, socially prescribed perfectionism had a positive effect on negative affection. A hierarchial strategy for multiple regression was conducted to examine the role of perfectionism. The result indicated that self-oriented perfectionism mediated the effect of communication on positive affection, and socially prescribed perfectionism mediated the effect of trust on negative affection. In addition, socially prescribed perfectionism mediates the effect of isolation on negative affection.

기존의 네트워크 환경에서 서비스 제공자들은 사용자들이 사용하고 있는 네트워크의 느린 속도와 가상 IP 사용으로 인해 빠른 대역폭과 대형 저장 공간, 그리고 고정 IP를 가진 서버를 운영함으로써, 사용자들에게 일방적으로 서비스를 제공하는 방식으로 발전해왔다. 그러나 인터넷 사용자의 폭발적인 증가와 함께 네트워크의 속도가 향상되어 각 사용자들은 서버를 경유하지 않고 사용자간 직접적인 파일 송수신을 할 수 있게 되었다. 각 단체에서는 이러한 P2P 환경의 장점을 이용하여 여러 P2P 응용프로그램들을 개발하였지만, 네트워크 그룹에 참여하기 위하여 프로그램 내부에 서버의 IP가 지정되거나 사용자가 직접 IP를 입력해야 하기 때문에 서버가 더 이상의 서비스를 제공하지 않는다면 일반 클라이언트를 사용하는 사용자들은 서비스를 제공받지 못하는 문제점이 발생하게 되었다. 본 논문에서는 이러한 문제점을 해결하기 위해 순수 P2P 환경에서 각 피어들은 인접한 피어로부터 다른 피어들의 IP를 얻어 목록으로 관리함으로써, 소켓으로 연결된 피어가 종료하여도 목록에 유지된 다른 피어에게 연결하여 네트워크 그룹에 지속적으로 연결 유지를 할 수 있는 기법을 제안하고자 한다. 이 제안기법은 죄초 실행시 기존의 방식과 같이 특정 피어의 IP를 지정해주지만, 이후의 동작과정에서는 어떠한 피어 IP도 지정하여 주지 않기 때문에 더욱 더 안정된 서비스를 제공받을 수 있다.

Most of comparative studies in science teacher education so far have been conducted in terms of teacher education policy, pre- and in-service training system and curriculum, and certificate system. While such superficial information can be readily obtainable, it does not necessarily enable us to make access to reality of science teachers' professional development in respective countries, because practice in professional development among science teachers is deeply embedded into respective socio-cultural environment or climate. In order to get information on reality in science teachers' professional development, alternative approaches of research should be developed. This paper aims at pursuing an alternative way to approach reality of Japanese science teachers' professional development. An email survey of free description method with 29 in-service science teachers with a variety of years of experience in Ibaraki Prefecture, Japan, revealed that Japanese science teachers have developed their expertise through very close daily-based communication with their peer science teachers. At least, within their consciousness, neither formal in-service training programs, nor pre-service training programs have had much stronger effects on their professional development than such non-formal, daily-based, deep, apprenticeship-typed or in some sense, family-typed communication. The results suggest that in order to conduct meaningful comparative studies, we should take much more attention to how to make access to reality of science teachers' professional development.

Lecture theatres and computing laboratories are common types of classrooms used for teaching and learning in this study; both were equipped with a computer network through which teachers and students can access learning management system, digital library, educational software, and so on. Students were divided into groups of two or three; each group of students collaborated on the worksheets in the laboratory and naturally sat together when attending a class held in the lecture theatre. The social organization of classroom learning would promote student learning but what drives student learning; how to engage students with learning; and how to maintain their interest in learning are of research interest in the present study. The study illustrated the theoretical and empirical links, student motivation has a relation to rich collaboration with peers, communication as verbal interactions as well as teacher-student interactions. These are within socio-cultural contexts for learning to take place. The study was extended to make comparisons of the motivational orientations between student genders. It was found that female students were keener on fun or enjoyment in learning, peer communication, and teacher's intervention, whereas male students were concerned more about digital learning tools, a positive working relationship, social reciprocity, and interpersonal relationships.

This study investigated the impact of a safety coaching program on the safety behavior and safety climate among expressway safety patrols. Four to seven patrols from each of the three branches participated in this study. The safety coaching program was developed based on the GROW model, with main contents including recognizing individual differences, exploring safety values, communicating near-misses, providing effective and efficient feedback, employing non-violent communication, and fostering commitment toward safety behaviors. Additionally, each session included self-monitoring and peer review of each item based on a critical behavior checklist developed for this study, with challenging goals set based on the monitoring and review. The safety coaching program comprised six sessions in three branches, while three other branches were assigned as a control group. A non-equivalent control group experimental design was applied. Dependent variables included observed and perceived safety behavior, safety climate, psychological safety, and feedback. The results indicated that the safety coaching program effectively increased patrols' safety behavior and safety climate. Furthermore, psychological safety and feedback improved. These findings suggest that the developed safety coaching program could serve as an alternative method to enhance safety management for expressway safety patrols. Finally, the implications, limitations, and directions for future research are discussed.

WebRTC (Web Real-Time Communication) is a technology that enables browser-to-browser communication. Therefore, a signalling mechanism must be negotiated to create a connection between peers. The main aim of this paper is to create and implement a WebRTC hybrid signalling mechanism named (WebNSM) for video conferencing based on the Socket.io (API) mechanism. WebNSM was designed over different topologies such as simplex, star and mesh. Therefore it offers several communications at the same time such as one-to-one (unidirectional/bidirectional), one-to-many (unidirectional) and many-to-many (bi-directional) without any downloading or installation. In this paper, WebRTC video conferencing was accomplished via LAN and WAN networks, including the evaluation of resources in WebRTC like bandwidth consumption, CPU performance, memory usage, Quality of Experience (QoE) and maximum links and RTPs calculation. This paper presents a novel signalling mechanism among different users, devices and networks to offer video conferencing using various topologies at the same time, as well as other typical features such as using the same server, determining room initiator, keeping the communication active even if the initiator or another peer leaves, etc. This scenario highlights the limitations of CPU performance, bandwidth consumption and the use of different topologies for WebRTC video conferencing.

Recently, cache sharing methods have been studied in order to effectively reply to user requests in mobile P2P networks. In this paper, we propose a cache sharing scheme based on a cluster considering the peer connectivity in mobile P2P networks. The proposed scheme shares caches by making a cluster that consists of peers preserving the connectivity among them for a long time. The proposed scheme reduces data duplication to efficiently use the cache space in a cluster. The cache space is divided into two parts with a data cache and a temporary cache for a cache space. It is possible to reduce the delay time when the cluster topology is changed or the cache data is replaced utilizing a temporary cache. The proposed scheme checks the caches of peers in a route to a cluster header and the caches of one-hop peers in order to reduce the communication cost. It is shown through performance evaluation that the proposed scheme outperforms the existing schemes.

Blockchain is a technology that directly connects each node to P2P method, except for the central server. A public blockchain is one of the blockchain types, anyone can participate without any restriction. If some node find nonce, which node can broadcasted data to all nodes. At this time, if a node that finds a nonce hides malicious code in the block, all nodes participating in the chain may be infected with malicious code due to the characteristics of the decentralization system of the blockchain. In this paper, to solve the problem that hackers can participate as an any node, we propose that a user with malicious intent can not participate as a node through a firewall with AI technology. This will improve the reliability of the propagated data over existing data.
