Currently the mobile augmented reality does not require supplemental hardware, such as markers like specific images or depth cameras, in order to acquire 3D environment information. This allows for increased accessibility and usability for the general user, and also broadened scope of development. The market research enterprise Counterpoint Research predicted that the growth of the augmented reality market will reach 70 trillion Korean Won by 2021. Application developments are also progressing. Wargaming, the developer of the global game World of Tanks, has launched an application that uses AR core at the GDC 2018. Thus, we must prepare for the impending augmented reality market and acquire top class augmented reality technology using 3D environment. This paper outlines the development of a game using AR CORE SDK to acquire 3D environment and Unity 3D game engine to combine camera images and 3D graphics, which all comes together to construct a natural augmented reality.

Edge computing, which is computing on the edge of the network, is becoming a market value as a means of overcoming the fear of communication disconnection and delay reduction, which are the technical weaknesses of cloud computing. Edge computing is continuously expanding applications in various applications such as safety industry, smart factories, autonomous vehicles, mobile communications, and AR/VR. Looking at edge computing trends from Microsoft, IBM, HPE, and Dell EMC, current edge computing must be understood as an integral binding technology and not as a simple complement to the cloud. This paper examines market trends in edge computing and analyzes the impact of edge computing on major related industries.

We have reviewed the potential impact of blockchain technology on the music industry by analyzing the views of academia and the industry experts. The music industry had rapid changes from the physical market to the digital market in the past decades. The consumers download and stream music online and mobile during the digital dominant market. While streaming music has been recently growing at a fast rate, fair distribution of revenue to the artists continues to be an issue. Some industry experts believe that the issue of fair distribution of revenue to the artist may be resolved using blockchain technology, while some are skeptical about the application or the duration of impact. The blockchain may enhance speedier payment using smart contracts, provide additional revenue and promote the music if excellent fan support is achieved. The positive impact on the music industry may only be possible if there are detailed consideration of the industry and careful understanding of the customers.

The purpose of this study was to select market variables that a foodservice company should consider when expanding overseas and to regional market analysis by variables. Twenty-three different variables were derived from 17 previous studies. These were: population, urbanization rate, women employed, enrollment in tertiary education, gross domestic product, value added by service, total number of mobile cellular telephone subscribers, number of internet users, total Asian highway, inward foreign direct investment, total service imports, inflation rate, international tourist arrivals, energy use by industry, growth rates of the food consumer price index, access to urban sanitation, per capita total expenditure on health, male life expectancy at birth, adult literacy rate, contributing women family workers, passenger car, and country risk assessment. The selected variables were collected as secondary data from the UN, Asian Development Bank, International Bank for Reconstruction and Development, and Michigan State University.

Laser-based crystallization techniques are ideally-suited for forming high-quality crystalline Si films on active-matrix display backplanes, because the highly-localized energy deposition allows for transformation of the as-deposited a-Si without damaging high-temperature-intolerant glass and plastic substrates. However, certain significant and non-trivial attributes must be satisfied for a particular method and implementation to be considered manufacturing-worthy. The crystallization process step must yield a Si microstructure that permits fabrication of thin-film transistors with sufficient uniformity and performance for the intended application and, the realization and implementation of the method must meet specific requirements of viability, robustness and economy in order to be accepted in mass production environments. In recent years, Low Temperature Polycrystalline Silicon (LTPS) has demonstrated its advantages through successful implementation in the application spaces that include highly-integrated active-matrix liquid-crystal displays (AMLCDs), cost competitive AMLCDs, and most recently, active-matrix organic light-emitting diode displays (AMOLEDs). In the mobile display market segment, LTPS continues to gain market share, as consumers demand mobile devices with higher display performance, longer battery life and reduced form factor. LTPS-based mobile displays have clearly demonstrated significant advantages in this regard. While the benefits of LTPS for mobile phones are well recognized, other mobile electronic applications such as portable multimedia players, tablet computers, ultra-mobile personal computers and notebook computers also stand to benefit from the performance and potential cost advantages offered by LTPS. Recently, significant efforts have been made to enable robust and cost-effective LTPS backplane manufacturing for AMOLED displays. The majority of the technical focus has been placed on ensuring the formation of extremely uniform poly-Si films. Although current commercially available AMOLED displays are aimed primarily at mobile applications, it is expected that continued development of the technology will soon lead to larger display sizes. Since LTPS backplanes are essentially required for AMOLED displays, LTPS manufacturing technology must be ready to scale the high degree of uniformity beyond the small and medium displays sizes. It is imperative for the manufacturers of LTPS crystallization equipment to ensure that the widespread adoption of the technology is not hindered by limitations of performance, uniformity or display size. In our presentation, we plan to present the state of the art in light sources and beam delivery systems used in high-volume manufacturing laser crystallization equipment. We will show that excimer-laser-based crystallization technologies are currently meeting the stringent requirements of AMOLED display fabrication, and are well positioned to meet the future demands for manufacturing these displays as well.

현행 항공교통이용자 분석은 주로 통계적인 분석이 주류를 이루고 있으나, 이동경로, 지역별 이용자 수, 공항접근 소요시간 등 세부적인 사항에 대한 분석이 어렵다는 한계가 있다. 한편 빅데이터 기술 발전과 데이터3법 개정에 따라 빅데이터 기반 교통분석이 활성화되고 있으며, 모바일 통신 데이터는 휴대전화 단말기의 위치를 상세하게 파악할 수 있어 교통분석을 위한 좋은 분석자료가 될 수 있다. 이에 본 연구에서는 기존 항공교통이용자 분석방법의 한계를 극복하기 위해 이동경로 전체를 분석할 수 있는 모바일 통신 데이터를 기반의 교통이용자 O/D(Origin/Destination) 추출 알고리즘을 제시한다. 본 연구에서 제시하는 알고리즘은 각 공항에 공항신호탐지 구역을 설정하고, 해당 구역의 기지국 접속이력을 토대로 항공교통이용자를 추출하고 해당 이용자의 출발지-도착지 경로상의 기지국 접속 데이터를 토대로 이동경로를 추정하는 것이다. 본 연구에서는 2019년 1~12월의 기간을 대상으로 모든 국내 공항에 대하여 국내/국제선 이용자에 대해 O/D를 추출하였다. 또한 추출된 데이터의 검증을 위해 모바일 통신데이터 기반 항공교통 이용자 O/D 데이터와 항공통계데이터에 대해 상관성 분석을 수행하였다. 이를 통해 총량에는 차이가 있으나(국내선 4.1, 국제선 4.6) 상관성 0.99로 상관성이 높아 활용 가능할 것으로 판단되었다. 본 연구에서 제시한 알고리즘은 기존과 다르게 항공교통이용자의 이동행태, 지역별/연령별 비율 등 폭넓고 상세한 분석을 가능하게 하며, 향후 공항관련 정책 마련이나 지역별 시장분석 등 다양한 분야에서 활용할 수 있다.

The mobile-phone which Camera was put on was released at the end of 2000 and dramatically puts up the deployment ratio because not only simple Camera but also a function that the photograph which I took is dispatched was added. It is the force that demand in this year presses 600,000,000 sale of a mobile-phone is estimated to be 960,000,000 of them in 2006, and to be able to include two errands with a support model after 3G. A person of entry to a camera-module appear much. In addition, the various kinds of products open markedly which a product comes to be known widely in the world, and the application range has opened widely, and considered QCDT come to be key issues for answer to market demand. By manufacturing industry, there is peculiar culture to each industry, camera-module is the composition the various industries. The construction of true Supply-chain becomes unavoidable to make a good product. I describe the point that the situation of each supply-chain and the direction for the future by the view point of module assembly maker.
