사물인터넷 시장은 미래의 핵심성장 동력으로 폭발적인 성장을 하고 있다. 이에 세계의 주요 기업들은 사물인터넷 시장 선점과 자사 중심의 생태계 조성을 위해서 사물인터넷 서비스를 경쟁적으로 제공하고자 노력하고 있다. 하지만 이러한 사물인터넷 서비스가 정착되고 기업의 발전에 기여하기 위해서는 사용자들이 진정으로 원하고 체감할 수 있으며 새로운 경험을 할 수 있는 사물인터넷 서비스를 제공하는 것이 필요하다. 이에 본 연구에서는 성공적인 사물인터넷 서비스를 제공하기 위해 사용자 가치 요인을 도출하였다. 이를 위하여 먼저 사물인터넷의 개념과 의미를 파악하고 사물인터넷과 관련한 문헌들을 고찰하여 사물인터넷의 트렌드 매트릭스를 도출하였다. 그리고 사물인터넷 관련 문헌에서 잠재적 서비스 가치 항목을 정리하고, 표적집단면접을 실시하여 문헌에 나타나지 않은 사용자의 실제적 욕구와 기대 항목을 추가하여 사용자 가치 요인을 도출하기 위한 문항을 정리하였다. 마지막으로 이렇게 준비된 문항을 활용하여 설문조사를 진행하였으며, 사물인터넷 서비스의 사용자 가치 요인으로 관리성, 관계성, 친숙성, 확장성, 단순성, 오락성, 안전성, 경제성, 보상성, 자동화, 신속성, 정보성, 환경성의 13가지 요인을 도출하였다. 본 연구는 사물인터넷 서비스를 이해하는데 기반 자료로 활용될 수 있으며, 사용자들이 원하는 사물인터넷 서비스를 개발하기 위한 기준이나 평가 항목으로 활용될 수 있을 것으로 기대된다.

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.

The purpose of the study was to give a help in making a successful expansion of fashion brand by making a close inquiry into an effect of the main brand in fashion brand on an image of the second brand and into an effect of satisfaction and loyalty for main brand on satisfaction and loyalty for the second brand. The study made a survey of the total eight brands including four main brands and each second brand, and used 217 questionnaires. The results of this study are as follows. First, The main brand image and second brand image did not match. Second, the satisfaction of the main brand affected the satisfaction of their second brand, especially in the main brand of the image, design, user experience, staff friendliness, variety of products and brands on display. Third, the ranking of main brand loyalty and the ranking of second brand loyalty were different. All the main brand loyalty had a significant effect on the second brand. The consumers who preferred the main brand had a high confidence and a strong tendency to repurchase.

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.
