The aim of teaching writing is not to memorize a single piece of knowledge but to acquire higher thinking that could be related to other fields using learners' various reading experiences and schemata. Among several strategies or techniques to write well, it is recommended to use a mind-map technique. A mind-map software applies the mind-map technique into computer for learners to study autonomously. However, the mind-map software is not common in educational fields yet and there are only few studies on the effect of it. Therefore, this study analyzed various curricula to extract the elements of writing and developed a mind-map software program which was applied and tested. As a result, the writing program using the mind-map software was effective in promoting learners' motivation and lowering anxiety. It also improved learners' competence of writing such as understanding, analytic thinking, creativity, ability to organize, and expression.

Mind map is a very useful technique for brainstorming. Therefore, it can be effectively used for collaboration as a creative group conception. However, existing mind map software is not possible to collaborate because it is difficult to share mind map or discuss among members. In this study, we developed a mind map system that can support collaborative work as well as individual authoring and editing. This can incorporate individual mind maps of members into mind map of team, share and discuss them, and modify the mind map. This is convenient because it does not require a separate program installation, and verifies usability to support the process of collaborative process through usability evaluation.

The use of the Internet of things plays a major role in the Fourth Industrial Revolution, and a series of tasks of accumulating, converging, analyzing and reusing various data and services becomes very important. Because the pace and scope if the paradigm shift in Fourth Industrial Revolution is so rapid and unpredictable, the development and utilization of a system to fulfill this role for IOT are urgently required. In this paper, we introduce the Web-based IOT management system, which connects the IOT with OKMindmap, which is a domestic open source software and service, and the Node-RED service. This system combines the advantages of OKMindmap with the advantages of Node-RED, which is capable of visual component based programming, so that it can easily and flexibly connect the IOT based on Web browsers, and various data and services can be integrated and linked. We developed a camera module, a temperature and humidity sensor module, and the motor control module in Raspberry PI basically, and tested the operation successfully. We plan to extend the IOT component gradually by using Arduino and System On Chip.
