The rate of donations made by individuals is relatively low in Korea when compared to other developed countries. To address this problem, we propose the DONA, an urban donation motivating robot prototype. The robot roams around in a public space and solicits donation from passers-by by engaging them through a pet like interaction. In this paper, we present the prototype of the robot and our design...
Various studies propose that robots can be an effective tool for language teaching and learning. Especially they have been remarkably successful in elementary English classes . The purpose of this study was to investigate some effects of a teaching assistant robot, Langbot, in elementary English classes in Korea. We adopted IROBIQ as Longbot for a pilot study. We designed some activities for elementary...
In this presentation, we introduce an open radio map based indoor navigation system. The system is implemented on a Google android phone and tested on 3rd floor, Main-building, KAIST Munji Campus, Korea. The open radio map for the system is constructed by partly participatory approach. That is, the radio map data for rooms and laboratories are collected by ordinary users of smart phones, and for corridors...
The application of ubiquitous technology in Korea has been expanded with city as the center, but establishing U-Technology utilization plan for farm village and forest is required now according to pan-national growth strategies recently came to fore including national balanced development, sustainable development, and green growth. Therefore, in order to organize the concept of U-Territory, U-Land,...
This paper describes DC railway loadflow algorithm that is essential process to determine the capacity of the energy storage system which is good at energy. By calculating the loadflow for 12 lines on Korea, the needs of energy storage devices are verified.
The train control system (TCS) plays the core role to secure the safety and punctuality for railway train operation. There are various systems applied to urban transit lines which are developed differently and independently from other countries. The national standard specifications and guidelines have been established and maintained for the TCS in Korea. As the requirements of the high-efficient and...
The value of national brand is important in these days. Korea realizes the importance of national brand value, and tries to improve it as well. However, it is only in industry and Korea is overlooking the important of national power. This paper is suggested the reformation of cultural products design. The National Museum of Korea is a representative of Korea and the subject of this paper is limited...
The importance of network among university, industry and research institute can not be overemphasized. In the paper, the concept of university, industry, and research institute network was briefly reviewed and policy case study was done for the Gyeonggi Province in Korea. In the Gyeonggi Province, the Industrial Innovation Cluster Committee (IICC) policy was developed to promote the network among...
As the competition between mobile telecom operators becomes severe, it becomes critical for operators to diversify their business areas. Especially, the mobile operators are turning from traditional voice communication to mobile value-added services (VAS), which are new services to generate more ARPU (average revenue per user). That is, cross-selling is critical for mobile telecom operators to expand...
Korea possesses a high-speed network infrastructure that excels those of other advanced countries, as a result of a series of network advancement projects; however, although small farming and fishing villages in remote places can access the Internet, the data rate remains low. As a result, various convergence services cannot be used in these areas, unlike in metropolitan cities and small and medium...
Conversion technology between IT(Information Technology) and automotive technics creates the new industry of ITS (Intelligent Transport systems) and the new paradigm in electronics, communication and traffic fields. Specially, Vehicular communication in ITS field is one of the most important technologies necessary to connect among driver, vehicle and provider to provide quality services. Solutions...
Software is widely used in the railway system such as train propulsion system, brake system, train control system, train detection system and driver display unit. Unfortunately, there is no software criteria and development procedure that are required to get the qualified software. Although analysis and evaluation of each step in the software lifecycle are the basic activity, direct coding to get...
In this paper, a test field of high-data rate PLC using overhead medium voltage power line (MV BPLC) for applications to automatic meter reading (AMR) and distribution automation system (DAS) is introduced. It was established in Jeju island, Korea and 8.2 km long. For the MV BPLC, a MV coupler for BPLC with internal impedance matching transformer was developed. For repeating, techniques of both time...
In general, solar array is used for primary power source of satellite. For solar array design, required power and voltage are considered to perform the mission successfully. Also, solar cell degradation and string failure at EOL (End of Life) are considered for its design. In this paper, solar array design that is reflected design consideration for Korea LEO (low earth orbit) satellite is introduced...
Electric vehicles are now drastically distributed among U.S.A, Japan and European Countries. Especially hybrid cars are main target of electric vehicle. Now the cars which can charge electricity from outer AC grid(110V/220V/380V) were made and they are called PHEV (plug-in hybrid electric vehicle). In 2012 PHEV will be produced in Korea. In this time it is very important that we predict its future...
Recently, Korea has made a plan to allocate CH 14~CH 51 (470 MHz-698 MHz) for DTV. Therefore, it is necessary to take into account compatibility and sharing between DTV and other potential service systems. This paper assumes that DTV operates on CH 51 (692 MHz~698 MHz) and radio microphones operate on CH 52 (698 MHz~704 MHz) in spare band, and then analyzes compatibility between DTV and radio microphones...
This paper presents the interference of ultra wide-band (UWB) sensor applied in Korea into wireless broad-band (WiBro) system based on orthogonal frequency division multiplexing (OFDM) using frequency of 2.3 GHz. The minimum coupling loss (MCL) method and spectrum engineering advanced Monte Carlo analysis tool (SEAMCAT) are used to evaluate the interference effects of UWB sensor on WiBro. The required...
This research applies a multi-perspective decision-making approach [6,7] and the concept of discounting or planning horizons as a framework to study the influence of culture on technology policy and management in Korea. Korea has invented the world's first metallic type and MP3 player and they had great opportunities to develop them earlier than other technologically advanced countries. However, these...
In this paper, we consider Starbucks stores in Korea, which have been spread most rapidly in the world, as an exemplary social network. We define two kinds of influence models and analyze the diffusive power of each node in a network. One is Dynamic Influence Model for time-varying diffusion analysis and the other is Static Influence Model for cumulative spreading power analysis. The physical features...
Due to the widespread use of cellular phones, various kinds of mobile services have been introduced to improve userspsila convenience, utilization, and entertainment. Since differences exist in technological infrastructures, government policies, cultures, and competitive landscapes, the configurations and utilization of mobile services vary in different countries. In this paper, we describe the differences...
