In this paper, we implemented the full stack platform design with MongoDB database of open source platform Raspberry PI 3 model. We experimented the triggering of event driven with acceleration sensor data logging with wireless communication. we captured the image of USB Camera(MS LifeCam cinema) with 28 frames per second under the Linux version of Raspbian Jessie and extended the functionality of wireless communication function with Bluetooth technology for the purpose of making Android Mobile devices interface. And therefore we implemented the functions of the full stack platform for recognizing the event triggering characteristics of detecting the acceleration sensor action and gathering the temperature and humidity sensor data under IoT environment. Especially we used MEAN Stack for developing the performance of full stack platform because the MEAN Stack is more akin to working with MongoDB than what we know of as a database. Afterwards, we would enhance the performance of full stack platform for IoT clouding functionalities and more feasible web design with MongoDB.

In a four-wheel independent drive platform, four wheels and motors are connected directly, and the rotation of the motors generates the power of the platform. It uses a skid steering system that steers based on the difference in rotational power between wheel motors. The platform can control the speed of each wheel individually and has excellent mobility on dirt roads. However, the difficulty of the straight-running is caused due to torque distribution variation in each wheel's motor, and the direction of rotation of the wheel, and moving direction of the platform, and the difference of the platform's target direction. This paper describes an algorithm to detect the slip generated on each wheel when a four-wheel independent drive platform is traveling in a harsh environment. When the slip is detected, a compensation control algorithm is activated to compensate the torque of the motor mounted on the platform to improve the trajectory tracking performance of the platform. The four-wheel independent drive platform developed for this study verified the algorithm. The wheel slip detection and the compensation control algorithm of the platform are expected to improve the stability of trajectory tracking.

Purpose The purpose of this study is to examine the effect that insecurity and autonomy of platform work have an influence on work-life balance and psychological well-being in an era of platform economy based on two characteristics of online platform work and self-determination theory. Design/methodology/approach This study suggested the structural equation model integrating two antecedents, insecurity and autonomy, work-life balance, and psychological well-being and proposed five hypotheses driven from the research model. A total of 334 valid samples were collected from platform workers by employing questionnaire including 24 question items of four constructs. Findings Three hypotheses were supported and one hypothesis was not supported at the significance level of 0.05. Insecurity of platform work has a negative influence on work-life balance at the significance level of 0.01, whereas insecurity of platform work has no a significant influence on psychological well-being. Autonomy of platform work has a positive influence on both work-life balance and psychological well-being at the significance level of 0.01. Work-life balance has a positive impact on psychological well-being at the significance level of 0.001. Insecurity have an influence on psychological well-being indirectly through mediation of work-life balance. Implications for academicians and practitioners were suggested.

This study explores the effect of experiential value of AR fashion platform on platform preference. Based on the SOR theory, the effects of visual appeals, entertainment, service excellence, and efficiency on platform attitudes, mediated by intrinsic enjoyment and escapism, are tested. The participants respond to the questions after watching the video clip, using an AR fashion platform. A total of 252 data is analyzed using SPSS 26.0 for descriptive statistics and reliability analysis and AMOS 26.0 for confirmatory factor analysis and structural equation modeling. The results show visual appeals, entertainment, and efficiency influence platform preference, mediated by intrinsic enjoyment. Entertainment also influences platform preference, mediated by escapism. The moderating effect of the AR service pre-experience is also explored. For the group with the AR service experience, entertainment and efficiency has a positive effect on intrinsic enjoyment, leading to AR platform preference. For the group without an AR service experience, only entertainment influences the AR platform preference, mediated by intrinsic enjoyment; however, there are no factors which increase escapism. The findings of this study contribute to find the marketing directions for the AR service users, by offering appropriate experiential values based on their prior AR experience.

Fashion brands communicate with consumers through the use of fashion films that are effective in the delivery of the image. This is because digital media (such as fashion films) are popular and accessible as well as effective in attracting people's attention. The reasons why fashion films have become a new fashion media among many others is becuase they are based on an existing platform. This study will examine offline platforms of fashion film: flagship store, fashion exhibition, and fashion show. The offline platform of a fashion film is a physical space where a fashion film can be exhibited and viewed as a medium that can effectively convey fashion film to consumers. As a research method, the concept of an offline platform of fashion film is established based on a literature review of fashion films and platform that is followed by an empirical case study. The study results show that the offline platform of a fashion film is in the progress of turning into an autotelic space where the consumption of such culture as cinema and theater has become possible.
