정보통신 기술의 발달은 학습 환경에도 많은 변화를 가져왔다. U-learning을 비롯해 많은 학습 방법들이 과거의 제한된 장소에서의 학습이 아닌 언제 어디서든 자유롭게 학습할 수 있는 환경을 제공하고 있다. 본 연구에서는 QR-Code와 U-learning을 이용해 학습자들이 시공간의 제약 없이 학습 할 수 있는 환경을 학습의 장인 학교에 접목시켜 스마트 러닝이 가능하도록 하였다. 학습자들의 흥미를 이끌어내어 원하는 장소에서 원하는 시간에 언제든지 학습이 가능하도록 하여 학습 능력 향상을 기대하고 나아가 자기 주도적 학습에 도움이 될 것으로 기대된다.

In the paper, we design a autonomous mobile robot for freight transportation and propose an operation method of the robot in the warehouse. In order to implement autonomous navigation, it is needed to recognize the position of the robot and track the path to the target. Previous methods are hard to change the workspace environment and need high cost to install and keep a maintenance of the system. The lifter of freight transportation robot is designed to load and unload a baggage through up and down motion. Also, ultrasonic sensor, RFID, QR-code and camera sensor is used to carry out various functions while the robot navigates in the various environment. We design an operation method of the mobile robot in order to effectively arrive a goal position and transport a freight. The proposed methods are verified through various experiments.

Recently, Kiosks, a wireless ordering system, has been introduced as the system where employees and customers order in person has disappeared in most stores. However, Drive-Thru, which is serviced in stores, still has a system where employees and customers communicate directly to order. In this paper, we propose the design of a Drive-Thru system in which customers order direct communication between Drive-Thru's employees and customers without facing them using QR-Code. The non-face-to-face Drive-Thru system aims to provide a more automated system by minimizing employees in the store. As a result, customers receive more accurate services and have the effect of improving the quality of consumption.

Purpose: This study aimed to investigate the effect of a video-based enteral nutrition education program using QR codes on the perception, knowledge, and performance of enteral nutrition for intensive care unit (ICU) nurses. Methods: This was a quasi-experimental study with a nonequivalent control group pre- and post-test design. The participants were nurses working at six ICUs within a single university hospital, with 55 nurses in the experimental group and 55 nurses in the control group. The video-based enteral nutrition education program using QR codes was repeated three times to the experimental group. Results: There was a statistically significant pre-post difference in perceptions between the two groups (Z = -4.04, p < .001) with 2.00 points (± 5.57) for the control group and 7.89 points (± 7.95) for the experimental group, in knowledge (Z = -7.48, p < .001) with 0.02 points (± 1.91) for the control and 4.18 points (± 2.33) for the experimental, and in performance (Z = -2.20, p = .028) with 0.06 points (± 3.96) for the control and 2.00 points (± 5.14) for the experimental. Conclusion: The video-based enteral nutrition education program using QR codes was effective in improving the perceptions, knowledge, and performance of enteral nutrition among ICU nurses. This enteral nutrition education program using QR codes in clinical education can contribute to evidence-based nursing practice by improving perceptions and knowledge of enteral nutrition.

This study explores the process of the actual content production and distribution, by creating a YouTube channel to promote the popular music contents produced by the researcher, which thus reflects the reality where the production of video contents rapidly increases. A YouTube channel titled "Alida Music", of which the focus was to promote indie musicians, was created on February 2019. The contents of 10 indie musicians were produced in one-take live format. The information of the indie musicians was displayed in the form of a screen business card, with their e-mail address and SNS account at the top. Therefore, this promotional design was named "Card Live". Promotional video contents marked with the QR code in the lower right on the screen were produced, along with the promotional phrase "Communicate directly with the artist through the QR code", which allows viewers to watch other contents of the indie musician when they scan the QR code. This research conducted a study on how to improve and promote "Card Live" contents of "Alida Music", which were produced through this process. A group interview targeting five indie musicians, among whom one participant deemed significant was selected to conduct a one-to-one in-depth interview. As a result of the study, the following three conclusions were drawn. First, YouTube was found to be the medium with the greatest influence and highest efficiency at the lowest cost. Second, the evaluation of the participants on "Card Live" were divided into the three categories: need for one-take live, the design elements of "Card Live", and scanning issues of the QR code. Third, there is a need for promotional methods that can effectively utilize the media aspects of YouTube: the channel management issues such as raising public awareness as well as the number of subscribers of "Alida Music" should be resolved and measures to effectively use various media including other SNS should be developed. In terms of its content, it is imperative to recruit diverse performers to make various contents, as well as to come up with ways to link "Card Live" contents with offline. Based on these results, "Card Live" contents should be further revised and complemented in order to provide interesting contents to consumers, which will further develop "Alida Music" as a platform where various musicians and companies meet, thereby inducing contracts with popular music agencies and generating advertising revenues. However, since this study was carried out only with the limited number of participants, future studies should include more participants to bring forth a variety of promotional plans and improvement measures. Also, in the era of consuming contents through smart devices, the fact that some features of "Card Live" were available only on PC, did not fully reflect the characteristics of the times. In the future research, various contents that smartphone users can access and view freely without PC should be produced.

이 논문은 비콘과 QR코드를 이용해 방문자 식별 및 원격제어를 구현한 스마트 도어락 시스템을 제안한다. 1인가구의 지속적인 증가에 따라 도어락에 원격제어와 보안의 필요성이 부각된다. 기존 논문에서는 동영상 전송방식, 블루투스 통신 방식 등 다양한 기술을 이용하여 구현한 도어락 시스템을 제안한다. 하지만 동영상 전송방식은 센서가 방문자를 오판단하는 경우가 발생하고, IoT기반의 실시간 스트리밍 기술을 이용한 도어락은 해제 후에 사용자가 집의 내부를 모니터링할 수 없다. 이 논문은 비콘과 안드로이드 어플리케이션, 라즈베리파이를 이용한 방문자 식별 및 원격제어를 구현한다. 또한 3D 프린팅을 이용하여 제작한 프로토타입을 보인다.

This paper proposes and implements an on-line instruction manual system which can generate the instruction manual page for the target device at the smartphone on the spot. The instruction manual app. on smartphone scans a QR code or reads NFC tag attached in the instruction manual management module embedded in the target device, and receives instruction manual data from the instruction manual management module through the Bluetooth communications and finally shows the refined instruction manual pages on the smartphone display using a Web-based templates. For the evaluation we embedded the instruction manual management module for an industrial generator with its instruction manual data. Assuming a circumstance of blackout we show that the proposed system can reduce the repair work within two steps compared to three steps in the existing one without the proposed system.
