Self-driving vehicles are a type of smart vehicle with the help of ICT technology, which means a vehicle that operates without the intervention of a driver.Vehicles with vehicle safety communication technology (V2X) applied use information detected from various sensors or other vehicles/infrastructures to enable the smart vehicle to accurately and quickly predict the driver's potential danger situation, contributing to more stable autonomous driving. In this paper, among V2X communication technologies, a vehicle-to-vehicle communication (V2V) simulation communication technology is used to present a scenario for preventing collisions in autonomous vehicles. A vehicle collision prevention system based on V2V simulated communication was implemented and the suggested collision prevention application scenario was demonstrated. The suggested collision prevention utilization scenario can be considered as one application case of V2V communication technologies that are currently being developed/applied.

빅데이터와 AI 의 인기에 힘입어 데이터 확보가 중요해지면서 대량의 개인정보가 무차별적으로 수집되고 있다. 그로 인하여 마이 데이터(Mydata)에 대한 관심 또한 대두되고 있다. 오늘날 데이터 수집의 주체들은 정보 수집시에 불필요하거나 대량의 웹 트래픽을 발생시켜 웹 자원을 소모하고 있다. 또한 그들은 정보의 소유자가 아닌 데도 불구하고 그를 이용하여 이득을 취하고 있지만 정보 소유자는 보상을 받지 못하고 있다. 정보의 활용에 대한 정확한 기록과 보상을 제공하고 웹에서의 불필요한 자동화 프로그램의 사용을 지양하기 위해 본 연구에서는, 블록체인(Blockchain)을 활용하여 사용자의 정보를 제어하는 시스템을 구축하고 기록된 정보를 바탕으로 구축된 웹 사이트 검색엔진을 제안한다.

Multi-tracking of general objects and specific faces is an important topic in the field of computer vision applicable to many branches of industry such as biometrics, security, etc. The rapid development of deep neural networks has resulted in a dramatic improvement in face recognition and object detection problems, which helps improve the multiple-face tracking techniques exploiting the tracking-by-detection method. Our proposed method uses face detection trained with a head dataset to resolve the face deformation problem in the tracking process. Further, we use robust face features extracted from the deep face recognition network to match the tracklets with tracking faces using Hungarian matching method. We achieved promising results regarding the usage of deep face features and head detection in a face tracking benchmark.

One of the characteristics of both on-line analytical processing(OLAP) applications and decision support systems is to provide aggregated source data. The purpose of this study is to discuss on the aggregation of multi-dimensional data. In this paper, we (1) examine the SQL aggregate functions and the GROUP BY operator, (2) introduce the Data Cube and MDX, (3) present an example for the practical usage of the Data Cube and MDX using sample data.

When content is presented within an appropriate context, that exposure for digital contents providers is most effective. We research on how DOI could increase the profitability of content distribution strategies. We examine traditional works of distribution channels and setup DOI-enabled scenarios.

In this study, four alternatives for the arrangement of Korean alphabets on computer keyboards are developed and analyzed to find the better design than the KS(Korean Standard) keyboard. Among the developed four modified models MOD 1 to MOD4, we suggest MOD3 as the best design which incorporates the keys usage frequencies and the compatibility of present standard.

This paper explored gifted students' perspectives on using educational technologies in their schools in the Saudi context. Adopting a descriptive research approach, a questionnaire was used to collect information from a sample of 196 gifted secondary school students in Jeddah. Findings showed that educational technology was used to a high degree, with an overall mean of 3.74 and 4.06 for the degree of importance of technological usage. Based on the findings, the researcher forwards some recommendations for effectively using such technologies to promote gifted students' abilities and talents.

This project is designed with the aim to facilitate the farmer or gardener to engage in green house systems and to improve agricultural technology. In order to reduce continuous monitoring of the soil parameters, excess time consumption for the farmers and excessive usage of water, "Smart irrigation and temperature control for a greenhouse system" has been developed. There are two different ways to irrigate the land namely traditional irrigation methods and modern irrigation methods.

The technology acceptance model (TAM) is a lot of cited in information technology adoption and usage researches. But TAM has been conducted primarily in volitional environments of the adoption of new technology. This paper discusses technology acceptance in accounting information systems to examine TAM with Characteristics of Organizations and Individuals in mandated using Combined Guard System. Combined Guard System is a scientific guard system that is composed of automated surveillance system, automated sensing system and control system. GOP Scientific Guard System is operated by GOP unit in Korean Army O Division from 2006. In this study, using the extended technology acceptance model, we have analyzed factors which affect the usage intention of GOP Scientific Guard System in mandated using environment. Based upon previous researches, we have selected Support of management unit, Training, Perceived Risk, Subjective Knowledge and Computer Self-efficacy, perceived usefulness, perceived ease of use, and usage intention as variables and proposed a research model. We collected 253 survey questionnaires from Korean army officer and soldier who are serviced at GOP unit in O Division, and analyzed the data using SPSS 12.0 and SmartPLS 2.0M3. According to the results by PLS analysis, According to the results by PLS analysis, Training and Subjective Knowledge did not affect Perceived usefulness, but the other hypotheses were accepted. And Perceived usefulness, and Ease of use influenced the Usage intention. The results of this study will increase Characteristics of Organizations and Individuals on GOP Scientific Guard System and eventually contribute to establishing the activation of Combined Guard System.
