I suggested the design learning environment based on affordance concept approach for supporting and improving learners' behavior and outcome for convergent design education in this study. The design learning space should be applied teaching and learning activity, especially learners' behavior, physical space condition to support the design thinking process. The design learning space needs openness, individuality and connectivity to support the learners' behavioral to immerse, participate, cooperate, understand, think and fulfill the design thinking process. The composition principles of the learning environment for convergent design education supports communication and collaboration among members for independence and interaction. The spaces for design research and teaching needs high privacy while facilitating visual communications through special materials and wall structure design. Also, for connectivity to improve the learners' physical and visual contact, the environment of the classrooms requires flexibility and mobility by providing an open space integrating unit cells for realizing learning purpose. These are provided by formed of an open structure for inducing visual communication and physical contact to involve the design activities and the mutual interchange.

Though weight manufacturing has in national gross production is decreasing, it has still a decisive role in economic growth of Korea, and foreign competitiveness of manufacturing has a great influence on our whole economy. Therefore, as this study speculates export competitiveness of manufacturing item by item, the results can be used for selection of strategic export-oriented products. The results of the analysis are summarized as follows: first, products that are found as competitive through analysis of trade specialization indexes are plastic, rubber, fabric, home electronic appliances, computers, communication equipment, automobiles and their spare parts. Second, electronic-electric industry such as semi-conduits, communication equipment, home electronics, computers was decided as advantageous through analysis of comparative advantages at present, while paper, print and publishing, and leather industries were classified as comparatively disadvantageous. Its political implications are presented as follows: Private corporations should develop more advanced technology and government should give more support to secure export competitiveness of manufacturing toward America. Governmental policies should be prepared to induce consistent and daring investment to technology-intensive products for export products with high-added value.

It is usually that some people who did not plan to buy anything walk into e-mart, but walk out with something in hands. Obviously, these people were stimulated and the result is purchasing something maybe are not really needed. As a consumer, sometimes we are interested in what somebody else is using, and sometimes we cannot help trying a kind of new drink when we found many of people around are drinking it. In this paper, conformity psychology's effect in the advertisement will be checked in the hope of helping improve the advertisement effectiveness.

In this paper, we present the study on the proposed design of a real-time transmission of a video from the drone to broadcasting station (OBVan) by using F8L10D-N LoRa Module. Nowadays, LoRa technology is proved to be the mass of low cost, long range machine-to-machine connectivity. Particularly in the field of broadcasting and communication system, F8L10D-N LoRa RF Module spread spectrum technology with long transmission distance and strong penetrative ability that is double stronger than traditional FSK as well as PSK modulation scheme.

This research want to discuss some issues about payment system of America. This research focuses on comparing ACH with Fedwire. Firstly Fedwire is the payment system for only large-dollar transfer(Large-Value Transfer System; LVTS), while ACH(Automated Clearing House)payment mainly applies a consumer account. Secondly ACH transaction is either credit or debit transfer, while Fedwire is only credit transfer. Thirdly the communication system of Fedwire has twoway method, telephonelike communication network, but ACH is oneway store and forward electronic mail. At present LVTS divides into RTGS(Real-Time Gross Settlement) and DNS(Deferred Net Settlement). However Fedwire uses either RTGS(instantaneous for every transaction) or DNS(net net transaction) but ACH uses only DNS(net net transaction). Fourthly ACH is substantially cheaper than the Fedwire payment. lastly security is important in both Fedwire and ACH, it is even more crucial in Fedwire In addition, for each transaction, Fedwire may entail individual instantaneous confirmation to the originator and notification to the receiver, whereas ACH do not.

This study begins with investigation of the purpose and background of the International convention on Standards of Training, Sertification and Watchkeeping for seafarers 1978, London(STCW) which will be put into force on and after 28th April 1984. Author tried to confirm those common points on requirement of the qualifications between the radio officer regulated it. the STCW Convention and radio communications between the radio officer regulated in the STCW convention and radio communication operator's general certificate in the Radio Regulations annexed to the International Telecommunication convention. Then, Japanese communications administration is taken as a model for the comparative analysis, as Japan and Korea have many resembling aspects, especially legal and social aspects. Therefore, as one of urgent tasks of Korean Communications Administration preparing for the STCW convention, Istressed on partial amendment of the Korean Radio Regulatory Act.

Recent development of IT industry including smart phones and communication technologies has resulted in rapid growth of Internet of Things (IoT) technology and relevant markets. The access to IoT is becoming easier thanks to the boards and IoT products, such as Arduino and Raspberry Pi. Large-scale business sites use IoT technology to manage inventories, but small-scale business sites do not. In the present study, We ported Linux-based Raspbian to Raspberry Pi, It utilizes web server communication to control the Arduino through the application We used a color sensor to figure out the kind of inventory. We also built a database using MySQL to store the data. We used raspberry pi to check whether the proposed system works and apply it to small-scale business.
