Sensors collect information for Internet of Things (IoT)-based services. However, indoor construction sites have a poor communication environment and many interfering elements that make it difficult to collect sensor information. In this study, a network was constructed between a Bluetooth Low Energy (BLE)-based IoT device based on a serverless IoT framework and a router. This experimental environment was applied to large- and small-scale indoor construction sites. Experiments were performed to test the communication performance of BLE-based IoT devices and routers at indoor construction sites. An analysis of the received signal strength indication (RSSI) graph patterns collected from the communication between the BLE-based IoT devices and routers for different testbed site situation revealed areas with good communication performance and poor communication performance due to interfering factors. The results confirmed that structural components of the building as well as the materials, equipment, and temporary facilities used in indoor construction interfere with the communication performance. Construction project managers will require improved technical knowledge of IoT, such as optimizing the router placement and matching communication between the router and workers, to improve the communication performance for large-scale indoor construction.

Purpose: This study explored how Indonesian banks utilize digital marketing communication strategies to optimize their distribution channels, leading to enhanced customer trust and brand loyalty. It examined specific methods such as sponsorships, social media, institutional partnerships, and mobile banking application features as key components of this digital distribution strategy. Research Design, Data, and Methodology: This study employed mixed methods design to assess digital distribution impacts. It involved 385 Jakarta bank customers. The sample size was determined using the Lemeshow formula. Results: The findings indicate that effective digital distribution strategies, including sponsorships, social media engagement, and user-friendly mobile banking applications, significantly enhance customer trust and loyalty. However, overly complex features may negatively impact loyalty. Conclusion: Thisstudy demonstrates a clear connection between the strategic use of digital marketing channels, such as sponsorships, social media, institutional partnerships, and mobile banking features, and the development of customer trust and loyalty. The results provide valuable insights to Indonesian banks in designing digital distribution strategies that prioritize building trust and fostering integrated customer interactions. Tailored digital marketing approachesthat optimize distribution can significantly enhance both trust and loyalty among Indonesian bank customers.

In today's world, the design industry is becoming more complex, with the development of networks such as the internet and revolutionary changes in information and telecommunications. As the demand for designers to cope with various situations occurring in these industrial sites or solve problems in practice promptly is required, a capstone design program was developed in collaboration with the industry. Capstone design classes have positive effects on creative problem solving ability, academic achievement and learning satisfaction by allowing students to think and experience the practical problems of the industrial field. It is also effective in improving communication, creative thinking and critical thinking. The purpose of this study is to search for talent training methods needed in the fashion industry and to develop effective programs through capstone design class studies conducted in the fourth grade of fashion design majors from 2017 to 2019 (6 semesters). Through these studies, the aim is to search for talent training methods needed in the fashion industry and to develop effective programs. If the capstone design learning method is used as a method of solving problems through close communication between the company and the educational field as an industry-academia cooperation system, it is expected to be positioned as a field-type human resource education method that is required in the industrial field.

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.

블루투스 4.0은 블루투스 저전력 에너지 근거리 통신 기술로서 블루투스 3.0에 비해 소비전력이 낮아지고 전파도달 거리도 70m 까지 길어짐에 따라 활용범위가 커지고 있어 전력소모가 적어 모든 기기가 항상 연결되는 사물인터넷 구현에 적합하다. 따라서 본 논문에서는 비콘 기술 현황을 조사하고 비콘 기술을 이용한 음식점 광고/주문 시스템 설계원리를 기술한다. 또한 블루투스 4.0 기술에 기반한 발신장치인 비콘의 설계와 블루투스 4.0 수신 장치의 설계를 보여주고 이와 연동하는 스마트폰 앱 설계 방법을 제시함으로써 본 설계 방법이 음식점 광고/주문 상용시스템에 제작에 유용하게 활용될 수 있음을 보여준다.

우리나라에 대학교육이 시작되고 지금의 발전된 대학들의 모습이 있기까지는 많은 변화가 있었다. 디자인 교육도 해방직전부터 시작하여 지금에 이르기까지 많은 변화 속에 다양한 전공들이 생겨났다. '도안과'라는 전공으로 시작되어 지금은 컴퓨터 정보화 시대를 반영이라도 하듯 멀티미디어디자인 전공까지 탄생하기에 이르는 맡은 변화를 가져온 것이다. 이러한 변화와 더불어 고과과정도 개정을 거듭하게 되었고 그 속의 교육과목 또한 그 시대를 반영하면서 변화 되어왔다. 시각디자인 전공도 그 예외는 아니었다. 특히 시각디자인 전공은 시각에 전달하고자 하는 모든 매체의 수용을 해야하는 전공의 특성상 컴퓨터라는 새로운 매체를 어떻게 수용하여 가르칠 것이냐 하는 문제가 매우 중요시되고 있는 시점이다. 기존의 교육과목과 컴퓨터그래픽디자인 교육과목을 적절히 수용하여 활용하는 대학교육이 하루 빨리 정착되어야 하기 때문이다.

In a SoC (system-on-chip) design, a design complexity is a big bottleneck. In order to overcome the design complexity, platform based design method is widely adopted for designers. Most complex SoCs need a heterogeneous design development environment for hardware and software co-design. In this paper, we discuss about some kinds of verification approaches with platform based design methodology at various abstraction levels of SoC design. We separate the verification process to two steps according to the different levels of verification. We employ a flexible SoC design environment to support simultaneous hardware and software development. We demonstrate the verification strategy of a target SoC design, IEEE 802.11a WLAN SoC.

As the demand of the LED for lighting that emits light by p-n junction is increasing, studies on heatproof plate technology is being conducted to minimize the temperature of the LED lighting. As for the temperature of the LED devices, their light emitting efficiency decreases and the maximum lifespan drops down to 1/5. Therefore there are heat dissipation studies going on to minimize the heat. For LED heat dissipation, aluminum heat sink plates are mostly used. For this paper, we designed heat sink that fits residential 20W COB LED Down Light; packaged the heat sink and 20W COB and analyzed and evaluated the thermal properties through a Solidworks flow simulation. We are planning to design the optimal heat sink plate to solve the thermal agglomeration considering TIM(Thermal Interface material).

유선 통신의 포화지역이나 도심에서 벗어난 인구밀도가 낮은 지역 둥에서 고속 광통신을 위해 최근 무선 광통신이 새롭게 기대되고 있다. 본 논문에서는 이러한 무선 광통신을 위한 송신 광학계를 설계하였는데, 광원으로는 수평(7$^{\circ}$)및 수직(18$^{\circ}$) 발산각이 다른 비대칭 타원형 빔을 발산하는 레이저 다이오드(중심 파장 830 nm)를 사용하였다. 제안되는 송신 광학계는 장거리 전송(500 m∼1500 m)이 가능하고, 장거리 전송 후 수신단에서 빔 직경(3 m) 및 에너지 분포가 대칭형이 되도록 설계되었다. 이를 위해 비결상 광학계인 송신 광학계의 평가법으로 에너지 전달 효율과 복사 조도 분포를 계산하였다.
