The major objective of this study is to develop and verify the KAUSAT-5 based on the modular 3U CubeSat standard platform. In the mechanical system design of a 3U standard platform, subsystem and micro equipment functions/performance should be integrated and miniaturized on micro-sized PCBs and electrical capability was maximized to accommodate multiple payloads. KAUSAT-5 is 3U-sized Cubesat which will be operated in Low Earth Orbit(LEO), which implements mainly two scientific missions; one is to observe the Earth through infrared camera and the other is to measure space radiation with a Geiger Muller tube. An additional mission is to verify the equipment(device) such as VSCMG and fuzzy logic-based MPPT internally developed. The results of ETB, qualification and acceptance level environmental tests were shown to verify standard platform and KAUSAT-5 Cubesat.

The emergence of diverse medical Internet of Things (IoT) devices has facilitated the collection and analysis of medical contexts to assess health conditions. However, the complexity of IoT-based systems for health assessment is quiet high and it requires high development cost, since the designs of the systems highly depend on the heath aspects to be evaluated. In this paper, we propose a design of the platform that provides generic functionalities to various health evaluation applications. We first define a metric for computing a health index, which is a generic health assessment model. And, based on the proposed generic health index, we propose a design of the platform to evaluate diverse aspects of the health including its hardware architecture, software architecture and database design. We describe the result of developing Rainbow Toilet System based on the proposed platform, and assess the practical applicability.

The objective of this study was to evaluate the characteristics of the fashion narrative from the commercial and artistic viewpoints by identifying and evaluating the attributes of the fashion narrative and analyzing the fashion narrative focusing on various cases according to fashion media. Louis Vuitton, a brand of the Louis Vuitton $Mo{\ddot{e}}t$ Hennessy (LVMH) group that operates the entire fashion community platform, is recognized as an influential luxury company with enormous capital and capabilities. This study targeted Louis Vuitton to examine the fashion narrative. The common results of Louis Vuitton's fashion narrative according to the communication platform are as follows. First, it emphasizes well-designed craftsmanship and artistry to convey the value and meaning of the brand. Second, it expresses the lifestyle of the bourgeoisie using traveling for finding life purpose, nature, and freedom as common denominators. Louis Vuitton connects, shares, and engages with customers by crossing the communication platform and trying multi-sensory changes based on the fashion narrative of the 'artification' message encompassing craftsmanship, innovation, and travel. The fashion narrative of Louis Vuitton applies tools (e.g., design, direction, stage, and props) differently according to the nature of media. In other words, the fashion narrative in the form of transmedia storytelling is a marketing communication strategy that indicates the representation means and direction of a brand's goals by remediating the brand narrative in various ways through the communication platform.

We propose a human-robot interaction(HRI) platform based on motion capture and mapping. Platform consists of capture, processing/mapping, and action parts. A motion capture sensor, computer, and avatar and/or physical robots are selected as capture, processing/mapping, and action part(s), respectively. Case studies-an interactive presentation and LEGO robot car are presented to show the design and implementation process of Kinect based HRI platform.

This paper proposes an ontology-based context-aware home healthcare platform employing environmental factors obtained from home. The proposed platform manages the health of home residents, and notifies relatives or a medical team of critical condition through context-awareness based on home ontology by using information sensed from various sensors. The ontology definition of context-awareness from the sensed information provides technically more precise decision for us. Therefore the platform can be aware of the health state of residents and environment by reasoning exactly from data gathered from various sensors and heterogeneous devices. The platform also can individually provide the customized service for users by setting priority for critical status that can be occurred in the health state of residents.

The pressure-transient on platform screen doors in side platforms caused by passing trains with various operating conditions have been investigated numerically. The transient compressible three-dimensional flow simulations are performed with actual operating conditions of two trains by adopting moving mesh technique. To achieve more realistic results, the detailed shape of train and the subway station including tunnels connecting the adjacent stations are represented in the computational domain. Numerical analyses are carried out for cases considering arriving/passing/departing train with or without train stopped on the opposite track, and both trains on the move in opposite direction. From the numerical results, the maximum pressure on the platform screen doors, which is predicted in the case of two passing trains, satisfied the design standards for similar stations.

Recently, payment method is one of the most hot issues for transaction of contents in mobile and internet markets. Many kinds of mobile contents services are rapidly growing with the combination of internet application services. Payment method algorithms are demanded for the stable transaction between producer and consumer. Security protocol algorithms are widely adapted for mobile Platform terminals. In this Paper, we described security mechanism for the current wireless internet services and compared with the performance result. There are security protocols that based on java machine platform or WAP protocols. The system is based on J2ME technology for the java mobile platform. Based on this technology, a security system is proposed for the service of mobile commerce electronic payment. The system is designed for the stability of transaction so that it enables to apply into many kinds of internet payment system.

The existing DSRC(Dedicated Short Range Communication) scheme has a limitation in providing various services through short-range wireless communication. Therefore, it is necessary to develop an intelligent WAVE/DSRC hybrid wireless platform that can improve data transmission speed and extend the effective communication range. This paper introduces WAVE/DSRC integrated platform technology using WAVE(Wireless Access in Vehicle Environments) to overcome the disadvantages of DSRC. First, the desinged software configuration of the WAVE/DSRC integrated platform is described. Then each task operation scheme and WAVE software design are described. By applying the WAVE/DSRC integrated platform, we can compensate the shortcomings of DSRC. It can provide more accurate and reliable services.
