The 5-aminolevulinic acid (5-ALA)-induced tumor fluorescence is a useful intraoperative marker for the diagnosis and the detection of various malignancies, but its use in meningioma is only reported infrequently. In meningioma, a complete resection of the tumor mass is crucial for the prevention of recurrence and postoperative morbidities. Deep sylvian meningioma is a rare type of meningioma where complete tumor removal is complicated by its deep anatomical location and close involvement with the middle cerebral artery. From our experience, 5-ALA-mediated fluorescence facilitated a safe excision whilst preserving critical neurovascular structures. To our best knowledge, this is first report from use of 5-ALA in a deep sylvian meningioma.

In this paper, we consider the distribution-free confidence intervals for the reliability of the stress-strength model when the stress X and strength Y depend linearly on some explanatory variables z and w, respectively. We apply these confidence intervals to the Rocket-Motor data and compare the results to those of Guttman et al. (1988). Some simulation results show that the distribution-free confidence intervals have better performance for nonnormal errors compared to those of Guttman et al. (1988), which are designed for normal random variables in respect that the former yield the coverage levels closer to the nominal coverage level than the latter.

The alkaloids of thirty five Korean plants which belong to Rhamnaceae, Sterculiaceae, Celastracea, Urticaceae and Rubiaceae were screened. Plant was extracted and solvent fractionated to yield ether soluble alkaloidal fraction and butanol soluble fraction. Each fraction was subjected to alkaloidal test by Dragendorff's reaction. The result showed eighteen plants strong positive, fourteen weak and six negative to alkaloidal test.

The photoreactivity of twelve anthraquinone derivatives was examined to evaluate its usefulness as a photo-reagent for the analysis of ginsenosides using photoreduction fluorescence (PRF) detection method. Among the tested compounds, 2-tert-butylandthraquinone (TBAQ), 2-chloroanthraquinone (CAQ) and anthraquinone (AQ) showed good characteristics as photoreagents. The detection limits of ginsenoside $Rg_{1}$PRF-HPLC method using TBAQ, CAQ or AQ as a photo-reagent were found to be ca. 35 ng, 50 ng and 50 ng, respectively.

코드리뷰는 소프트웨어의 신뢰성을 향상시키며, 개발 기간을 단축시킨다. 기존의 코드리뷰 도구들은 문법적인 오류는 검출하지만, 논리적인 오류를 찾아내지 못하는 한계가 있다. 본 논문에서는 Git 히스토리를 이용하여 코드 간의 연관성 그래프를 만들고, 이를 이용하여 논리적인 오류를 찾아내는 도구를 구현하였다. 코드상의 논리적 오류를 검출하여 프로그램 개발을 용이하게 하고, 내부에 잠재되어 있는 결함을 예방할 수 있다.

In this paper, fabricated is a motion capture and attitude detection system for Head Mounted Display HMD composed of three low-price and low-grade micro gyroscopes and a micro-controller, To calculate attitude of a body, modified INS algorithm is used. Because the micro gyroscope has much bias drift error, scale factor error, and run-to-run bias error, the motion of a body can not be measured exactly if the general INS algorithm and micro gyroscopes are used. To reduce the errors, three accelerometers can be used. In this case, however, the size and power consumption become too large to use in HMD system. The modified INS algorithm use the grid map and the characteristics of the human motions.
