  • The purpose of this study is to propose the effective development a fashion coordination website by computer graphics and web animation programs. Today, the internet fashion shopping malls come into the spotlight as the way of marketing. The amount of clothing products sold on the internet shopping mall and interest in the website design is increasing. This means many people consider that the web site design is one of the most important thing to lead customers to purchasing. For this reasons, this study develop fashion coordination items which was designed by the computer graphics software named 'photoshop 6.0'and propose the more visual effect of fashion coordination web image which was designed by animation software named 'flash 4.0'. As a result of this study. 1 It can accumulate a database of trend garment. 2.

  • In the Internet of Thing (IoT) framework, massive machine-type communications (MMTC) have required large spectral efficiency. For this, non-orthogonal multiple access (NOMA) has emerged as an efficient solution. Recently, a non-successive interference cancellation (SIC) NOMA scheme has been implemented without loss. This lossless NOMA without SIC is achieved via correlated superposition coding (SC), in contrast to conventional independent SC. However, conventional minimum high-correlated SC for only 2-user NOMA schemes was investigated in the lossless 2-user non-SIC NOMA implementation. Thus, this paper investigates a 3-user low-correlated SC scheme, especially for an inflated achievable sum rate, with a design of 3-user low-correlated SC. First, we design the 3-user low-correlated SC scheme by taking the minimum sum rate between 3-user SIC NOMA and 3-user non-SIC NOMA, both with correlated SC. Then, simulations demonstrate that the low correlation in the direction of the first user's power allocation inflates the sum rate in the same direction, compared to that of conventional minimum high-correlated SC NOMA, and such inflation due to low correlation is also observed similarly, in the direction of the second user's power allocation. Moreover, we also show that the two low correlations of the first and second users inflates doubly in the both directions of the first and second users' power allocations. As a result, the proposed 3-user low-correlated SC could be considered as a promising scheme, with the inflated sum rate in the future fifth-generation (5G) NOMA networks.

  • 스마트폰과 같은 단안 카메라를 이용하여 이동 궤적을 추정하고, 주변 3차원 영상을 구성하는 기술은 실내 위치 추정뿐만 아니라 메타버스 서비스에서도 핵심이다. 이 기술에서 가장 중요한 것은 이동하는 카메라 중심의 좌표를 추정하는 것인데, 본 논문에서는 기하학적으로 이동 거리를 추정하는 새로운 알고리즘을 제안하였다. 첫 번째와 두 번째 사진으로 3차원 물체점의 좌표를 구하고, 첫 번째와 세 번째 사진의 일치되는 특징점을 이용하여 이동 거리 벡터를 구한 후에, 세 번째 카메라의 원점 좌표를 이동하며 3차원 물체점과 세 번째 사진의 특징점이 일치되는 위치를 구한다. 실제 연속적인 영상 데이터에 적용하여 그 가능성과 정확성이 검증되었다.

  • 최근 인터넷을 기반으로 사물을 연결하여 사람과 사물 간의 정보 소통을 가능하게 하는 지능형 서비스로서 사물 인터넷 서비스(IoT)에 대한 관심이 증가하고 있다. 특히 스마트 기기의 발전과 더불어 실내 위치 기반 서비스에 대한 수요는 급격히 증가하고 있다. 실내 위치 정보 측정을 위해 BLE(Bluetooth Low Energy) 기술의 iBeacon이 제공하는 기본적인 신호만을 이용하면 신호 간섭 등의 다양한 이유로 신뢰할 수 없는 신호 데이터로 인해 실내 위치 정보의 신뢰도는 현격히 낮아지게 된다. 본 논문에서는 iBeacon의 신호 정보로 부터 신뢰성 있는 위치 정보를 얻기 위해 유전 연산을 통해 효과적이고 신뢰도 높은 위치 정보를 얻는 기법을 제안한다.

  • 우리가 살아가는데 있어서 인터넷이란 일상생활에서 없어서는 안 될 중요한 인프라가 되었다. 그러나 이러한 사이버 공간이 확장되고 일상화 되면서 여러 가지 역기능을 동시에 가져다주었다. 이러한 역기능을 최소화하기 위해서는 사이버공간에 적용될 새로운 질서가 정립되어야 한다. 사이버침해는 정보사회가 초래한 가장 심각한 문제 가운데 하나이다. 사이버 상에서는 상대방이 보이지 않으므로 그에 대한 죄의식이 희박하고 불안함도 적으며, 사이버 범죄의 처벌에 대한 무지도 생각할 수 있다. 본 연구에서는 공공부문과 민간부문에 대한 사이버침해정도를 알아보고, 공공부문과 민간부문의 사이버 침해현황을 분석하고 이를 바탕으로 사이버침해사고에 대한 대응방안을 제시하고자 한다.

  • Smart city is currently the main direction of development. The automatic management of instrumentation is one task of the smart city. Because there are a lot of old instrumentation in the city that cannot be replaced promptly, how to makes low-cost transformation with Internet of Thing (IoT) becomes a problem. This article gives a low-cost method that can identify code wheel instrument information. This method can effectively identify the information of image as the digital information. Because this method does not require a lot of memory or complicated calculation, it can be deployed on a cheap microcontroller unit (MCU) with low read-only memory (ROM). At the end of this article, test result is given. Using this method to modify the old instrumentation can achieve the automatic management of instrumentation and can help build a smart city.

  • By the increase of internet usage, communicating online became an everyday thing. Thereby various people have experienced profanity by anonymous users. Nowadays lots of studies tried to solve this problem using artificial intelligence, but most of the solutions were for non-real time situations. In this paper, we propose a Telegram plugin that detects swear words using word2vec, and an algorithm to find the target of the sentence. We vectorized the input sentence to find connections with other similar words, then inputted the value to the pre-trained CNN (Convolutional Neural Network) model to detect any swears. For target recognition we proposed a sequential algorithm based on KoNLPY.

  • Smart metering is one of the most implementable internet-of-thing service. In order to implement the smart metering, a wireless communication network should be newly designed and evaluated so as to satisfy quality-of-service of smart metering. In this paper, we consider a wireless network for the smart metering implemented with multi-purpose wireless chips and channel coding-functioned micro controllers. Especially, channel coding is newly adopted to improve successful frame transmission probability. Based on the successful frame transmission probability, average transmission delay and delay violation probability are analyzed. Using the analytical results, service coverage expansion is evaluated. Through the delay analysis, service feasibility can be verified. According to our results, channel coding needs not to be utilized to improve the delay performance if the smart metering service coverage is several tens of meters. However, if more coverage is required, chanel coding adoption definitely reduces the delay time and improve the service feasibility.
