본 연구에서는 디지털 신호에 포함되어 있는 잡음을 효과적으로 제거하기 위한 방법으로 프로그램 가능한 디지털 FIR 필터를 제안한다. 이러한 필터는 Altera의 FPGA(Field Programmable Gate Array)인 cyclone II EP2C70F89618를 이용하여 설계하고 구현하였다. 데이터 신호 잡음 제거 알고리즘을 바탕으로 한 영상 신호 제거 결과는 출력 영상으로부터 알 수 있듯이 필터 적용 후 출력 영상은 적용 전의 출력 영상에 비해 월등히 구분이 가능한 출력 영상 특성을 보임을 확인하였다.

The prolonged untact era, which has continued since the end of 2019, further accelerated the spread of distribution platforms that provide cultural contents in digital form. Digital content distribution platforms are fiercely competing in the market as the central axis of cultural content planning, production and distribution. In this study, we apply the open innovation theory as a competitive element of digital content distribution platforms to assess whether competitiveness can be secured in terms of multilingualization of content.

Lone Death is increasing as elderly population increases. Lone elderly is vulnerable in society for many reasons. This paper explores digital solution to protect solitary in society. First, sensor and AI care robot can be used to collect digital data and situation check. Second, digital device is checked regularly and visiting is expanded in digital environment. Third, digital emergency security system should be established. Fourth, user education is to be regularly carried out including complementary education.

Characteristics of digital broadcasting are multi-channel, high-definition and multi-function. especially, multi-function is enable us to do a variety of services except for an image and a voice. This paper, therefore, is analyzed propagation environment in Busan into ETRI model application about 지상파 DMB service. It takes to be simulated in Busan area around the mountains area and high building. So it measures the electric field strength in standards. Distribution pattern are similar with mutually in the 이론 and real measurement. Even areas are almost the same, but urban areas and mountains are different with mutually. Therefore, we conclude that ETRI propagation model and theoretical modeling in a free space in Busan area is not suitable.

This video is based on the newly emerged next-generation Media 360 VR. With the development of technology, digital content has developed and the opening of the COVID-19 pandemic untact era, people have found content that they can enjoy without going directly. 360 VR is a next-generation media that allows users to enjoy content in a three-dimensional manner as if they went to the site without having to go to the site. Using this, we would like to study the effective creation of local promotional videos.

The purpose of this paper is to find the direction by analyzing the synchronization phenomenon and the change rate of apartment charter rate in Korea, Seoul, Busan, Daegu, Gwangju and Daejeon. For this purpose, this study used a total of 239 monthly data from January 2000 to November 2019 in Kookmin Bank housing statistics. In the correlation analysis, Korea showed the highest relationship in order of Seoul, Busan, Incheon and Daegu. Seoul showed a low figure of 0.3 without any distinctive features from other cities. On the other hand, Busan, Daejeon and Daegu showed high correlations. As a result of the regression analysis, Korea and 5 major cities were all moving in the same direction with positive(+) values. And Busan and Seoul responded significantly to Korea. In the shock response, Korea is most shocked by the change in Seoul. Daegu is relatively shocked by Busan and Daejeon. Seoul's charter rate has declined most strongly in the last three years. Therefore, it is time to be careful not to incur losses due to gap investment. If we look at the relationship between the charter rate and the sale price in future studies, we can better understand the Korean apartment market.

인포믹스 유니버설 서버(IUS)가 국내에서 본격 발표됐다. 지난해 2월 일러스트라사를 인수한지 거의 1년만에 양사의 기술력 결합이 '객체관계형 DBMS, 인포믹스 유니버설 서버'로 결실을 맺게 된 것이다. 한국인포믹스는 지난달 18일의 서울행사를 기점으로 대전, 대구, 부산 등지의 지방로드쇼도 이달 11~13일중에 가질 예정이다.

Mini-implant has been reported as an alternative method to conventional diameter implants in the treatment of mandibular anterior region with narrow ridge. However, one-piece type mini-implant showed biological and technical complications, such as peri-implantitis by residual cement and prosthetic detachment. Recently, one-piece type mini-implant with additional retentive structure has been introduced to increase the retention and stability of the mini-implant. The mini-implant is based on spreading the upper retentive structure with a spreader and connected it with the inner surface of the zirconia prosthesis. In two cases, we tried to reduce these complications through the mini-implant on the narrow mandibular anterior region, and it was possible to reduce the overall treatment period through a digital system. In this case report, restoration using the digital mini-implant system showed improvement of patient satisfaction on the aspect of function and esthetic in the narrow mandibular anterior region.
