A jamming design scheme to disturb target position estimation of a bistatic multiple-input multiple-output(MIMO) radar system is presented. The proposed method exploits the received signals from distributed multiple electronic sensors and combines them to produce a jamming signal. The proposed algorithm can eliminate the target by transmitting the delayed sum or the weighted sum of the received senor signals. Simulation results confirm the performance of the proposed method.

The article presents the concept of ICT - competence, which is considered as the most important characteristic of professional competence, which includes a combination of the following components: motivational-value (orientation of the individual to the development of his ITC-competence in future professional activities); technological (complex of skills and abilities of ICT activities); cognitive (a system of knowledge of modern technologies of future professional activity); it is determined that the pedagogical support of the formation of ICT competence of future specialists is the individualization of the process training, due to their personal and professional needs and the specifics of a regional university, providing the necessary conditions for the implementation of this process.

This study presents a new fashion wearable product, a classical music stage costume design, using an Arduino LilyPad that can control light-emitting diodes(LEDs) and a sound sensor that can set an environmental range of LED light. As a theoretical background, LED fashion design research and stage costume design research status were reviewed, and Arduino LilyPads, sensors, LEDs, and batteries required for LED stage costume production were investigated. Based on prior research, the LED stage costume design for the soprano stage was presented in a three-step process of design planning, development, and production, and an actual prototype was produced. This process produced meaningful information and materials for making clothes with the added function of a wearable computer. In particular, fashion designers or fashion majors can easily access the Arduino LillyPad and use not only LEDs, but other light emitting materials. It is expected that it will be used as a basic material for the use of the Arduino LillyPad that can develop new creations that have been utilized.

The article assesses the functioning of the DE system or a separate educational institution, where it can be carried out on the basis of developed criteria or on a regulatory basis. The assessment was carried out on the basis of a qualitative and quantitative nature by comparing the actual state of affairs with a certain "ideal" (educational standard), which must be defined and used as a kind of benchmark against which the assessment is made. Conducted an assessment based on a regulatory framework that represents an alternative approach. It has been emphasized that the exceptional difficulty in determining the ideal indicators (norms) of the activities of universities, it has been found that the normative approach, in which the activities of traditional and open universities are compared, taking into account the differences in social, cultural and economic conditions, is the most acceptable.

The trend of satisfying consumer needs (payment for mobile communication, music services, cab ordering, banking products, and food delivery) on a unified online platform has shaped a digital ecosystem, an instrument creating a unified space of economic interaction. Representatives of e-commerce are major stakeholders in the development of such tools. In particular, subscription services (multiservice subscriptions) allow users to create their own ecosystems based on their personal preferences. The rate of subscription service use is growing around the world, yet understanding of the peculiarities of development of this e-commerce sphere is limited due to insufficient research.The study aims to determine the motives and barriers to the use of subscription services (multiservice subscriptions) by consumers and their relationship with consumer characteristics.Proceeding from an online survey of 200 users, the study determines the relationship between the gender and income of consumers and their use of subscription services, motives and motivators for using subscription services, and barriers to the choice of a particular subscription service. The obtained results may serve as a basis for managerial decisions in e-commerce and for improving the effectiveness of marketing solutions.

The techniques of estimating angle of arrival(AOA) have played a key role for enhancement of wireless communications using array antennas. Among those techniques, the superresolution algorithms, such as MUSIC and ESPRIT, calculate the covariance matrix of the array output vectors which are observed at the array antennas, and then by using eigen-decomposition of the covariance matrix, they estimate AOAs of the received signals with high accuracy. However, superresolution algorithms based eigenvalue decomposition fails to estimate AOAs under multipath environments. Under multipath environments, it is difficult to estimate AOAs of the received signals due to coherency and high-correlation. To resolve coherent signals, the covariance matrix is calculated by using the conventional spatial smoothing technique, and then the techniques based on eigen-descomposition is applied. The result of the conventional spatial smoothing technique, however, is obtained at the cost of losing effective spatial aperture. Moreover, the conventional technique ignores any information in the cross-correlations of the array outputs the subarrays. As the result, the performance for AOA estimation is degraded. In this paper, we propose a new spatial smoothing technique, which consider the cross-correlation for subarrays. By computer simulation, the AOA estimation performance of the proposed method is compared with the conventional method and evaluated.

본 연구에서 제작한 음악 플레이어인 Symphony(이하 심포니)는 사용자의 음악적인 공감을 돕고, 그에 따른 음악을 기반으로 한 2차 창작의 접근성과 자유도를 높여주는 기능을 포함하는 복합적인 프로그램이다. 기존 플레이어는 음원의 유통과 선별적 재생에만 초점을 두는 경향이 있는데, 심포니는 음악 플레이어의 개념을 사용자 입장에서 확장하여 가사 시스템, 춤 시스템, 플레이어 스킨, 사운드 비주얼라이저, DSP 설정 및 실시간 DSP 스크립팅 등을 추가하거나 개선하였다.

본 논문에서는 on-line을 통한 교육방법의 하나인 e-learning(Web Based Instruction)을 활용한 음악과 수업모형을 개발하여 교육적 활용 효과를 검증하였다. 웹 기반 교수학습 자료를 구축하고 각종 학습 자료를 탑재하여 수업에 활용하였으며, 교육 효과를 보다 정확히 알아보기 위해 수준별(상,중,하) 3개 그룹으로 나누어 e-learning 기법을 적용 사전평가 및 사후평가를 통하여 얻어진 결과를 통계 처리하여 검증하였다. 본 논문에서는 학습자의 능력과 필요에 따라 능동적인 학습이 이루어지도록 하였다. 개별학습, 반복학습 및 자기주도적 학습을 진행할 수 있도록 구성하였으며, 그 결과 구체적이고 실질적인 학습 효과를 얻을 수 있었다. e-learning 활용수업을 실시한 실험 집단 전체에서 off-line 수업을 실시한 통제집단보다 학습 성취도에 있어서 효과적인 것을 확인할 수 있었다. 상위, 중위 그룹의 학생들에게는 웹 기반 교수학습 활용수업이 학습효과에 있어서 큰 차이가 없었지만 하위 그룹의 학생들에게는 크게 효과적인 것으로 나타났다.
