We investigated the physicochemical properties of brown rice by cultivar to select cultivar suitable for making brown rice porridge. The moisture content of the brown rice ranged from 8.79~11.78% with the highest varieties being ‘Geonyangmi’. The crude ash and crude lipid content ranged from 1.02~1.65% and 1.65~3.26%, while the rest were similar except for ‘Daebo’. Crude protein also had the lowest ‘Daebo’ and generally glutinous rice showed higher crude protein content than common rice. The hardness showed that ‘Seolgaeng’ and ‘Keunnun’ were the lowest, and ‘Haiami’ was the highest. In the RVA analysis, the setback was in the range －80.61~22.44 and was low in the order of ‘Wolbaek’, ‘Baekjinju'', and ‘Dongjinchal’. As a result of water binding capacity (WBC) measurement, ‘Sindongjin’, ‘Geonyang’ and ‘Samkwang’, were high in common rice, and ‘Dongjinchal’ and ‘Hwaseonchal’ were high in glutinous rice. Generally, solubility and swelling power in common rice was found to be lower than in glutinous rice. As a result, ‘Samkwang’ is considered suitable for brown rice porridge production because of high WBC, breakdown, and low setback.

국가기관과 기업은 정비사를 양성을 위한 고등학교부터 대학교, 기업 훈련센터 같은 교육기관을 만들어 숙련된 정비사로 훈련시키려고 많은 노력을 하고 있다. 하지만 교재를 이용한 이론교육과 현장에서 사용하지 않는 장비를 이용한 실습교육으로는 제대로 된 정비교육을 진행하지 못하며 특수 장비를 활용한 교육이나 위험한 상황을 가정한 정비의 교육은 매우 위험하여 영상이나 사진으로 교육을 진행하고 있었다. 최근에는 VR과 AR을 접목하여 단순정비에서 특수정비까지 시뮬레이션으로 안전하게 상황을 체험하고 문제를 해결하는 효과적인 교육 시뮬레이션이 연구되고 개발되는 사례가 많이 있다. 본 논문에서는 다누리 VR과 DisTi Engine, Remote AR을 비교분석하고, 유니티 엔진 기반으로 외부에서 전달된 정보를 기반으로 콘텐츠를 디바이스 화면에 최적화하여 출력하는 AR API 를 소개하고, VR 디바이스인 HTC Vive의 컨트롤러와 HMD의 정보를 실시간으로 수집하고 수집된 정보를 파일에 저장하는 VR API를 구현한 사례를 소개했다. 본 연구에서 구현한 API를 사용하면 콘텐츠를 제작할 때 도움을 줄 수 있을 것이다.

The fast pyrolysis of biomass (larch) in a circulating fluidized bed pyrolyzer was performed and the physico-chemical characteristics of biocrude-oil was investigated. Standard sand was used for fluidizing material and various reaction temperatures from 400℃ to 550℃ was applied. Wood (larch) sample was examined thorough proximate analysis and thermogravimetric analysis (TGA). From the results of the sample test, thermal decomposition characteristics of wood (larch) was investigated. Various analyses were carried out to determine the physicochemical properties of biocrude-oil such as Higher heating value (HHV), water content, viscosity, ash content and microscopic anaysis. The maximum biocrude-oil yield was 49.9wt.% at 550℃. At this temperature, HHV and water content were 4562.0 kcal/kg and 13.8wt.%, respectively. From the study results, wood (larch) has potential as an alternative energy source.
