본 연구는 인플루언서 마케팅에서 경제적 대가 표시 여부가 소비자 태도 형성에 어떠한 영향을 미치는지 설득지식 모델의 관점에서 분석하였다. 이를 통해 인플루언서 마케팅이 나아가야 할 방향과 인플루언서가 견지해야 할 태도를 제시하였다. 실제 활동중인 유튜브 인플루언서의 콘텐츠를 활용하여 20~30대 성인 남녀 458명을 대상으로 실험을 진행하였다. 실험은 온라인 설문조사 업체를 통해 온라인으로 진행되었으며, 인플루언서와 브랜드에 대한 사전태도를 검사한 후, 2(경제적 대가 표시)X2(노트북/맥주), 총 네 개 집단에 무작위로 배치하여 자극물을 제공한 뒤, 설득지식 활성화 정도 및 사후태도를 측정하였다. 실험 결과, 경제적 대가를 표시하지 않는 것이 표시할 때보다 더 많은 설득지식의 활성화를 야기하였다. 또한, 경제적 대가를 표시하는 것이 더 긍정적인 인플루언서 태도를 형성하였으며, 브랜드 태도에는 유의하지 않았다. 설득지식 활성화 수준에 따라 구분한 집단 간의 차이는 고활성화 집단이 저활성화 집단에 비해 인플루언서와 브랜드에 대한 태도 모두에 부정적인 태도를 형성했다. 본 연구에서는 소비자들이 광고에 대한 지식을 충분히 축적하여 스스로 광고를 필터링할 수 있고, 광고를 인지함으로써 그에 대한 태도를 결정할 수 있다고 가정하였으며, 이에 대한 유의한 시사점을 도출하였다. 나아가 인플루언서 마케팅에 관한 방향성을 제시하고, 그 과정에서 인플루언서가 견지해야 할 태도를 제시하였다는 점에서 의의가 있다. This study examined how the presence of economic support disclosure affects consumer attitudes toward influencer marketing from the persuasion knowledge model perspective. An experiment using the content of currently active YouTube influencers was conducted among 458 adults in the age range of ‘20-’30s. This study used a 2 (Presence vs. Absence of economic support disclosure) x 2 (Notebook computer vs. Beer advertisements) factorial design. The experiment started with a pre-test survey asking about attitudes toward influencers and brands. Four experimental groups were randomly assigned to stimuli and asked to complete a post-experimental survey measuring attitudes and the degree of persuasion knowledge activation. Results showed that the group without economic support disclosure presented higher persuasion knowledge activation than did the group with economic support disclosure. Further, the group with economic support disclosure exhibited a more positive attitude toward influencers than did the group without economic support disclosure. However, there were no differences between the groups with and without economic support disclosure in attitudes toward brands. The group with high persuasion knowledge activation level was more likely than the group with low persuasion knowledge action level to form a negative attitude toward influencers and brands. The current study posed that consumers would build attitudes by accumulating sufficient knowledge about advertisements (ads), filtering the ads, and perceiving the ads. This study contributed to offering a direction of influencer marketing and understanding influencer attitudes toward marketing.

Excavators are universal equipment used in many fields due to their high applicability and economics to various kinds of work. However, the environment in which the excavator is used is very poor, and users are exposed to various noises, vibrations, and dusts, as well as high risk of industrial accidents such as falling rocks and falling. Therefore, it is necessary to prevent the danger of the user when working in the hazardous area. In addition, various sensors are installed to collect and analyze a lot of information for the safety of the equipment. However, the current technology has the disadvantage that the system configuration is complicated and expensive, and the cost increases because the equipment must be collected again when attached to the test equipment going abroad. Therefore, in this paper, we construct an Internet Database for 1.5ton excavator and construct a system that can remote system the excavator while reducing development cost using commercial microcomputer.

This paper presents an AI-based rotating machinery failure diagnosis method, using multiple sensors. Today, industrial sites are showing great interest in applying condition monitoring system because it can minimize the losses due to non-operation of the equipment and also by monitoring the equipment, immediate responses to possible unexpected situations can be carried out. The ultimate goal of monitoring system is to prognose and diagnose possible events that can occur in the future for the prevention of further fatal damages. Accordingly, various methods of monitoring and prediction technologies using vibration sensors have recently been developed. However, the demand for developing a corresponding complex solution is increasing in line with the advent of the 4th Industrial Revolution and the development of the computer industry. Therefore, a more reliable failure diagnosis method is presented through the establishment of an AI-based monitoring system using current, tacho and temperature sensors along with vibration sensors.

The combination of mechanical, hydraulic, electronic components, and any other modern technology becomes a very complex mechatronics system. At the same time, construction machinery must also meet these expectations regarding durability and ease of operation. This causes time-consuming, malfunctions, and commissioning procedures for equipment manufacturers and suppliers. Their solution is to increase virtual simulator usage in the development precess. In order to complete the simulation, the parameter must be stated in fixed form. In this paper, we will design the virtual hydraulic cylinder model and its parameter for the electric excavator by using least square method.
