  • The Internet of Things(IoT) market is growing exponentially as a core growth engine of the future. Major companies of the world are competitively providing the IoT services to dominate the IoT market first and create ecosystem around their companies. In order to establish the IoT services and contribute to the related industry, they will need to make efforts to provide the IoT services that the users desire, and which the users can have new experiences with. Thus, we attempted to draw out the user value factors to help successful IoT service development. For this purpose, we explored the meaning and concept of IoT, drew out a trend matrix of IoT through the literature review related to IoT and conducted a survey through the user values established by the literature related to IoT and the focus group interviews. As a result, we identified thirteen user value factors of the IoT services, which are manageability, relationship, familiarity, expandability, simplicity, entertainment, safety, economic feasibility, compensation, automation, rapidity, informativity and environment-friendliness. This study is expected to be used as a basic material in understanding the IoT services and as standards or assessment items to develop the IoT services that the users want.

  • The study on social robots has been actively conducted in the robot research community. In the area of robot design, however, there are few studies regarding robot motions that are one of the methods for interaction between humans and robots. This is a preliminary study to find preferred human motions that can be applied to social robots. We conducted a two-phased empirical study about preferred human motions. In the first phase, four representative human motions, such as 'greeting', 'I don't know', 'positive answer', and 'giving', were captured through 28 body makers and video recording. 10 young and 6 elderly Singaporeans participated in the motion capture process. In the second phase, the communication efficiency, emotion, and satisfaction of the human motions recorded in the first phase were measured by a questionnaire and 31 young Koreans, 35 young Singaporeans participated to investigate cultural differences. We drew the conclusion that motions used in the same culture are efficient in communication and also give friendliness and satisfaction. In addition, regardless of user's culture, young people's motions and female motions were preferred in terms of communication efficiency, emotional aspect, satisfaction.

  • A multi-dimensional thermal-hydraulic system analysis code, MARS 1.3.1, has been developed in order to have the realistic analysis capability of two-phase thermal-hydraulic transients for pressurized water reactor (PWR) plants. As the backbones for the MARS code, the RELAP5/MOD3.2.1.2 and COBRA-TF codes were adopted in order to take advantages of the very general, versatile features of RELAP5 and the realistic three-dimensional hydrodynamic module of COBRA-TF. In the MARS code, all the functional modules of the two codes were unified into a single code first. Then, the source codes were converted into the standard Fortran 90, and then they were restructured using a modular data structure based on "derived type variables" and a new "dynamic memory allocation" scheme. In addition, the Windows features were implemented to improve user friendliness. This paper presents the developmental work of the MARS version 1.3.1 including the hydrodynamic model unification, the heat structure coupling, the code restructuring and modernization, and their verifications.their verifications.

  • This paper studied about the design and implementation of tactical communication network simulator in order to obtain tactical communication network parameter, such as link capacity and routing plan, and a number of exceptional cases that may occur during actual deployment by conducting simulation of a large-scale tactical communication networks. This tactical communication network simulator provides equipment models and link models of commercial OPNET simulator for tactical communication network. In addition, 6 types of simulation scenario writings convenience functions and traffic generation models that may occur in situations of tactical communication network environment were implemented in order to enhance user friendliness. By taking advantages of SITL(System-In-The-Loop) function of OPNET, the tactical communication network simulator allows users to perform interoperability test between M&S models and actual equipment in operating simulation of tactical communication network, which is run on software. In order to confirm the functions and performance of the simulator, small-scale of tactical communication network was configured to make sure interoperability between SITL-based equipment and a large-scale tactical communication network was simulated and checked how to cope with traffic generated for each network node. As the results, we were able to confirm that the simulator is operated properly.

  • Computer simulations are widely used to analyze passenger safety in simulated traffic accidents. ATB, Articulated Total Body, is a computer simulation model developed to predict gross human body response to such dynamic environments as vehicle crashes and pilot ejections. ATB, whose code is open, has high flexibility and application capability that users can easily insert defined modules and functions. ATB is, however, inconvenient as it was coded in FORTRAN and it needs a formated input file. Moreover, it takes much time to make input files and to modify coding errors. This study aims to increase user friendliness by adding a preprocessor program, WINATB(WINdows ATB), to the conventional ATB. WINATB, programmed in Visual C++ and OpenGL, uses ATB IV as a dynamic solver. The preprocessor helps users prepare input files through graphic interface and dialog box. An additional postprocessor makes the graphical presentation of simulated results. In these case of the frontal crash, the rear impact and the side impact, the simulation results obtained by WINATB and MADYMO(MAthematical Dynamic Model) are compared to validate the effectiveness of WINAIB.

  • In recent years, much attention has been paid to the development of intelligent vehicles that integrate automotive technology into the information technology, with the aim of improving user friendliness and stability. The representative function is a autonomous driving and a cruise control. In designing such vehicles, it is critical to address the real-time issues (i.e., real-time vehicle control and timely response). However, previous research excluded the real-time scheduling. We develop a model car with unmanned cruise control, design the real-time scheduler using cyclic executive to easily adapt the model car, and provide some insight into potential solutions based on various experiments.

  • This study identifies key determinants and types of participation in UCC Services. The research examines the how the major factors in perception of social presence, fun and entertainment, self-expression, arousal, human relations, positive feedback, information sharing, monetary business opportunity, and user friendliness of web structure contribute to participation in UCC Services. The data used in this study were collected by a web-based survey so that 629 internet users were available for analysis. Some of the practical implications of the results are follows. We have categorized that the type of people participating in UCC Services were readers, modifiers, remixers, and creators. Digital consumers directly connected with other consumers by producing their own digital contents. Multiple regression analysis among the creators group was not included due to small sample size. Self expression, fun and joy and the convenience of the web interface showed strong positive significant impacts on the UCC Service participation of all participation types. Information sharing, other's positive reputation and arousal showed a positive significant impact on the modifiers or remixers type groups. Monetary business opportunity and human relations were not significant in any UCC type group.
