다양한 연령층에서 시청자가 늘어나고 있는 개인방송에서도 VR 서비스가 확대되고 있다. 기존의 VR 방송은 360도 카메라로 촬영된 영상을 시청자들이 VR로 보거나 개인방송 크리에이터들이 HMD를 착용하고 콘텐츠를 플레이 하는 영상을 시청자들이 시청하도록 구성되어있다. 시청자들의 몰입감과 흥미를 더욱 유발하기 위해 본 논문에서는 시청자의 입장에서 크리에이터가 진행하는 방송도 시청할 수 있고, 그 콘텐츠를 직접 즐길 수 있는 선택적 방송 시스템을 제안한다. 제안된 시스템은 기존의 시스템보다 시청자로 하여금 몰임감을 향상시키고 참여 한계를 극복할 수 있다.

정보통신기술의 발달에 따라 컴퓨터, 스마트폰과 같은 스마트 기기가 대중화됨에 따라 개인 블로그나 SNS 등을 기반으로 하여 개인이 다양한 콘텐츠를 생산하고 공유하는 커뮤니케이션 플랫폼인 1인 미디어가 활성화 되었다. 효율적으로 1인 방송시스템을 구축하기 위해서는 기존 방송 시스템의 체계는 유지하면서 개인의 협소한 공간을 효율적으로 활용할 수 있는 방안을 요구하게 된다. 따라서 본 논문에서는 각각의 방송장비들을 노트북, 어플과 같은 스마트 기기와 연동시켜 효율적이고 편리한 1인 미디어 방송 시스템을 구축하기 위한 방법을 제안하였다.

In the analysis of the mass distribution and SMD (Sauter Mean Diameter), planar laser imaging technique Is a convenient and useful one when compared to the mechanical patternator or PDPA (Phase Doppler Particle Analyzer). But for the accurate usage of this laser technique, it is required to compensate the signal attenuation and to find the attenuation coefficients. In the present research, we considered effects of the spray distributions on the attenuation coefficient and improved the accuracy of planar laser imaging technique by the reduction of errors issuing from the signal attenuation.

With its critical pending task of putting the management into the right track, it is extremely important for the Korea Railroad Corporation to incorporate more reasonable distribution into train consists to cut down its operation costs and attain higher income surplus in the Metropolitan Train Business. Furthermore, for Jung-ang Line soon to be operated without any crew on-board, more adequate train formation looks very indispensable mainly to satisfy transportation demands as well as enhance the passenger safety. This paper will examine the Jung-ang Line with hourly-basis congestions and inter station O/Ds to get the better operation schedules and trainset numbers.

Urban has been operating Korail and the local autonomous entity in Korea. Over 70 LRTs will be constructed in the future, but it is hard to manage them due to structural deficit from construction debt, so Public finance plays a very important role in order to overcome a deficit. Therefore, it is necessary to plan detailed analysis and planned system about the expenditure of the amount which is borrowed from country and local government and business income from railroad companies like government grants, PSO. This research wishes to grasp the problem and present model about reasonable and efficient financial program, analyzing about increasing import and expenses of Urban.

Pulsed supersonic liquid jets injected into an ambient air are empirically studied by using a high pressure ballistic range system. Ballistic range systems which are configured with high-pressure tube, pump tube, launch tube and liquid storage nozzle. Experimental studies are conducted to use with various impact nozzle geometry. Supersonic liquid jets are generated by an impact of high speed of the projectile. High speed liquid jets are injected with M = 3.2 which pressure is 1.19 GPa. Multiple jets which accompany with shock wave and pressure wave in front of the jet were observed. The shock-wave affects significantly atomization process for each spray droplets. As decreasing orifice diameter, the averaged SMD of spray jets had the decreasing tendency.

Various types of alkaloids observed in several herbal medicines were analyzed by electrospray ionization tandem mass spectrometry in positive ion mode. In the present study, MS/MS spectralpatterns were investigated for eight-types of alkaloids (aporpine, protoberberine, tetrahydroprotoberberine, benzylisoquinoline, protopine, phthalide, morpine, and bisbenzylisoquinoline). For aporpine- and protoberberine-type alkaloids, main fragmentations occurred at substituted groups on rigid ring structures, not showing ring fusion. Interesting fragmentations due to iminolization and retro-Diels-Alder (RDA) reaction were observed in MS/MS spectra of protopine- and tetrahydroprotobereberine-type alkaloids. Also, several types of fragmentations such as inductive cleavage and ${\alpha}$-cleavage, or bond cleavage between two ring structures were observed depending on their structural characteristics. These fragmentation patterns are expected to allow instant classification of the specific alkaloid type in various MS/MS spectra of alkaloids.

본 논문에서는 매입형 영구자석 동기전동기로 Belt-Type ISG(Integrated Starter Generator)를 설계하였다. 전동기는 저속영역에서 동손이 크고, 고속 영역에서는 철손의 비중이 크게 나타난다. ISG의 경우 전동기로 동작하는 저속영역은 동작시간이 짧기에 효율이 크게 중요하지 않지만 발전기동작은 고속영역에서 장기간 이루어지기에 이 구간에서 효율을 높이는 것이 중요하다. 특히 분포권에서는 전체 손실성분 중에서 회전자의 영구자석 기본파와 고조파 기자력에 의해 발생하는 치에서의 철손이 가장 큰 비중을 차지한다. 본 논문에서는 분포권에서의 철손에 대해서 분석하고 주된 손실의 원인인 치에서의 철손을 저감하는 설계를 수행하여 효율을 향상시켰다.
