The method and process of research and development (R&D) is changing when we develop artificial intelligence (AI), and the way R&D results are dispersed is also changing. For the R&D process, using and participating in open-source ecosystems has become more important, so we need to be prepared for open source. For product and service development, a combination of AI algorithm, data, and computing power is needed. In this paper, we introduce ETRI AI Strategy #4, "Expanding AI Open Platform." It consists of two key tasks: one to build an AI open source platform (OSP) to create a cooperative AI R&D ecosystem, and another to systematize the "x+AI" open platform (XOP) to disperse AI technologies into the ecosystem.

This article aims to analyze the experience of designing and operating a class model linking undergraduate and graduate students in engineering education and suggest its development direction. To achieve these objectives, the undergraduate-graduate linked class model was applied to community problem-solving education and a case was analyzed. It also specifically presented the process of how we design the class model and what the actual operational performances and improvements are. This study found that undergraduate and graduate students could build integrated and horizontal cooperative relationships in their classes through undergraduate-graduate linked education and, particularly, graduate students could gain meaningful educational experiences. However, it was difficult to obtain tangible performances through the team activities of these students within a semester. In order for engineering colleges to operate undergraduate-graduate linked education, it would be necessary to provide a longer and more systematic educational environment and better curriculum. The study tried to seek specific tasks and ways to improve them.

Last year, the Autonomous Vehicle Act was enacted to respond to deployment of autonomous vehicles. But the Act stipulates the operation of autonomous vehicle pilot zones, In addition, in order to analyze autonomous vehicle accidents and establish a reasonable damage compensation system, the Automobile Damage Compensation Guarantee Act was revised. But, It is necessary to seek plans for institutional development such as detailed concepts of self-driving cars and driving, a security certification system for securing safety of autonomous cooperative driving, and enhancement of the effectiveness of special cases related to personal information processing. I would like to seek ways to improve the legal system to respond reasonably to the deployment of autonomous vehicles.

With the recent opening of The National Library for Individuals with Disabilities, interests in library services for the disable have been increasing. For the purpose of promoting library services for the disabled all the more, the study is to provide cooperative plans in policy between the social welfare and the library and information service based on library perceptions of social workers as specialists in disability and welfare fields. Cooperative plans in policy provided by this study are as follows: (1) The unique communication channel between librarians and social workers should be constructed through social networks. (2) Public relations on the value and necessity of both the library and librarians should be enhanced. (3) Education on the expertise of the social welfare for librarians should be enriched. (4) Clear-cut identities between librarian's and social worker's tasks should be established.

The proposed cooperative 3D modelling system enables more efficient modeling works by improving current cooperation systems. Current 3D modeling tasks work on off-line and most of works are cooperation systems which communicate by files. These cooperation system cannot be interactive, occurs time delay while feedback and must have some programs which can read the files. This paper solves these problems using web that has the characteristics of network and proposes new cooperation system form. Using WebGL(Web Graphics Library) which is proposing technology in technical realization of Web 3D modeling, we make 3D objects in web browser and these objects can be manipulated by server-client communication. Therefore, if people use this system, they can use real time interaction and feedback. Also this system lowers a software installation necessity and can access everytime if web browser is installed.

With the explosive proliferation of smart devices that may be connected to the fast Internet, virtual desktop interfaces(VDI) are being implemented in enterprises allowing employees to work anywhere anytime in the same technological environment. As this kind of systems are intended to raise the work performance, a research model is constructed from the review of research literature on service quality and work design. The model consists of VDI system service quality (ubiquity, availability, compatibility, security and ease of use), system satisfaction, task performance and job satisfaction. As VDI is designed as a support system for cooperative work, the task interdependence adopted from the work design theory is postulated here as moderating the effect of user satisfaction on task performance and job satisfaction. 147 data points were collected by a survey of VDI users in a global firm and subjected to PLS analysis. Interestingly, ubiquity and compatibility seem to be not statistically significant for user satisfaction while availability, security and ease of use of VDI system are statistically significant. Task interdependence is found to be a relatively strong mediator between system user satisfaction and task performance, however, interestingly, the coefficient come out as negative. This may indicate that the influence of VDI user satisfaction on task performance would not be high in highly interdependent tasks. Considering that VDI is intended for supporting 'interdependence' in cooperative work, this finding is a bit surprising. In-depth discussions are made in the discussion followed by future research directions.

In this research, we observed the co-works among novice and expert science teachers who were involved in a science teacher association and explored their interactions. The science teacher association is K-12 science teachers' gathering near Seoul. This study is a case study with the participant observation and the private interview of 8 novice teachers and 3 expert teachers. Based on the collected data, interaction between novice and expert teachers was categorized as seven types; question and answer, demonstration, presentation, co-working, providing materials, listening, and showing interest. Several factors supporting such an active interaction were derived from this study; 1) Teachers perceived well about the importance and the merits of co-working with other science teachers. 2) The open and cooperative environment of the science teacher association supported teachers' interaction. 3) There were tasks that teachers needed to co-work such as the science fair and the science camp. 4) There were opportunities of interactions for publishing books and developing modules. 5) Lots of expert teachers were willing to help and co-work with novice teachers. We found that novice teachers could continue to grow in terms of the professional development under interactive, continuing and cooperative environment with expert teachers.

Agricultural Extension Services in Korea have accomplished a significant role in self- sufficiency of rice, a national staple food, through green revolution in 1970's; supplying green vegetables even during the winter season through white revolution in 1980's; and establishing technical agriculture by organizing rural leaders and 4-H members. In 1990s changes were made in international situations under the Uruguay Round multilateral trade negotiations and inauguration of the World Trade Organization. This was followed by localization of the extension staffs and the functions of extension services in Korea changed dramatically from national government to local governments. Thus, a weakened national function resulted in loosening of the linkages of research and extension in central government and local extension offices. Difficulties were reported in diffusion of new agricultural technology and efficient management of extension personnel. Developmental tasks for better extension services for the 21st century in Korea would include recovering national functions of agricultural extension, and developing a new paradigm for extension service. This should include the following measures; 1) Cooperative extension service should be adapted to involve national as well as local governments and non-government organization. 2) The target groups for extension services should be expanded to include farmers, noel residents as well as urban consumers. 3) The role of the extension service should cover agricultural technological diffusion of innovations as well as managerial skills and leadership development for rural organizations. 4) Extension services should be introduced to small farmers as well as consultation services for advanced farms. Diversified approaches should be employed for mama effective services. 5) Pre-service as well as in-service education should be offered to secure better extension educators equipped with knowledge, understanding and abilities on agricultural technology, information, agricultural philosophy, instructional methods and communication skills.
