본 논문에서는 한국전자통신연구원 가상현실연구센터에서 개발한 탁상형 디지털 편집 시스템의 시제품인 "솔거"를 소개한다. 솔거는 PC 환경에서 MPEG2 데이터들을 처리하고 편집하는 통합형 비선형 편집기로, Directshow 기반의 서브모듈(sub-module)로 개발된 여러 필터들을 기반으로 다양한 시각/음향효과 처리를 제공한다. 이외에도 자유로운 모션 벡터 방향을 줄 수 있는 타이틀링 툴과 정지 영상을 편집할 수 있는 페인팅 툴을 갖추고 있다. 솔거의 특징은 시스템의 구성 가격을 낮추기 위하여 하드웨어 부가 장치 없이 모든 서브모듈을 소프트웨어만으로 구성하였으며 Directshow 기반의 필터개발로 시스템의 확장성과 이식성을 높였다. 이식성을 높였다.

As a basic research for development of the domestic portable XRF spectrometer, we discussed the analytical results of bench-top and portable XRF methods for RoHS materials of the Cd, Pb, Hg, Cr(IV), polybrominated biphenyls(PBB) and polybrominated diphenyl ehters(PBDE). The instrumental parameters such as measurement time of bench-top and portable XRF were optimized using certified reference materials of polyethylene and polypropylene with 5 hazardous materials of 0~1,200 mg/kg. The quantitative analysis of total-Cr, total-Br, Cd, Hg and Pb in certified reference materials and plastic samples were compared by empirical method, fundamental parameter method of bench-top XRF and portable XRF.

Background: A national health care initiative recommends routine spirometry screening of all smokers over age 45 or patients with respiratory symptoms. In response to the recommendation, new, simple, and inexpensive desktop spirometers for the purpose of promoting widespread spirometric screening were marketed. The performance of these spirometers was evaluated in vivo testing with healthy subjects. However, the clinical setting allows spirometric assessment of various pathologic combinations of flow and volume. Objective: The aim of this study was to compare the accuracy of a desktop spirometer to a standard laboratory spirometer, in a clinical setting with pathologic pulmonary function. Method: In a health check-up center, where screening pulmonary funct test was performed using the HI-801 spirometer. Subjects who revealed the ventilation defect in screening spirometry, performed the spirometry again using the standard Vmax spectra 22d spirometer in a tertiary care hospital pulmonary function laboratory. Pulmonary function test with both spirometer was performed according to the guidelines of the American Thoracic Society. Results: 109 patients were enrolled. Pulmonary function measurements (FVC, $FEV_1$, PEFR, FEF25%-75%) from the HI-801 correlated closely (r=0.94, 0.93, 0.81, 0.84, respectively) with those performed with the Vmax spectra 22d and showed the good limits of agreement and differences between the 2 devices; FVC +0.35 L, $FEV_1$ +0.16 L, PEFR +1.85 L/s, FEF25%-75%-0.13 L/s. With the exception of $FEV_1$, FEF25%-75%, these differences were significant(p<0.05) but small. Conclusion: The HI-801 spirometer is comparable to the standard laboratory spirometer, Vmax spectra 22d, with high accurary for $FEV_1$ and FVC and acceptable differences for clinical use.

In this paper the safety problems of bench grinder have been reported. The safety status of bench grinders in 169 companies in Kyungbuk province was investigated. It was found that the two most important safety problems are the improper installations of workrests and the use of side (instead of front) of the grinding wheels.
