민법은 유언의 자유를 인정하여 피상속인으로 하여금 자기의 재산을 자기의 의사대로 처분할 수 있는 자유를 인정하면서도, 유언자유의 원칙을 무제한적으로 관철할 경우 발생할 수 있는 여러 가지 폐단을 방지하고자 유류분제도를 규정함으로써 피상속인에 의한 재산처분의 절대적 자유를 제한하고 있다. 이처럼 유언자유의 원칙과 법정상속 간에 존재하는 모순을 해결하고자 도입된 제도가 바로 유류분제도이다. 유류분제도가 유언자유의 원칙과 법정상속제도의 절충안이라고 일컬어지고 있는 것도 이러한 이유에서이다. 근래 선고된 대법원 2012. 5. 24 선고 2010다50809 판결은 유류분반환청구권의 행사방법, 유류분권 내지 유류분반환청구권의 양도, 공동상속인이 아닌 제3자에 대한 유류분반환청구권의 행사 등 주요 법적 쟁점들을 망라하고 있다는 점에서, 학리적(學理的)으로 매우 중요한 의미를 갖는다. 이에 본고(本稿)에서는 이 판결을 소재로하여 유류분반환청구권의 행사에 관한 법적 쟁점들을 검토하였다.

The products from polymer pyrolysis at $450^{\circ}$ are cooled with ice, then liquid and gaseous portions are analysed by gas chromatography. Di-2-ethyl hexyl sebacate column, silicone oil column, silica gel column and tetraethyleneglycol dimethylether column, which was most effective for the separation of hydrocarbon gases, are used. Identification of isomers could be secured more effectively by gas chromatography than mass spectrometry. Elucidation of the mechanism for thermal decomposition of polymers could be done through the identification of pyrolysis products. Although more extensive work is needed, some patterns of polymer pyrolysis are discussed.

Region of interest (ROI) is the most informative part of a medical image and mostly has been used as a major part of watermark. Various shapes ROIs selection have been reported in region-based watermarking techniques. In region-based watermarking schemes an image region of non-interest (RONI) is the second important part of the image and is used mostly for watermark encapsulation. In online healthcare systems the ROI wrong selection by missing some important portions of the image to be part of ROI can create problem at the destination. This paper discusses the complete medical image availability in original at destination using the whole image as a watermark for authentication, tamper localization and lossless recovery (WITALLOR). The WITALLOR watermarking scheme ensures the complete image security without of ROI selection at the source point as compared to the other region-based watermarking techniques. The complete image is compressed using the Lempel-Ziv-Welch (LZW) lossless compression technique to get the watermark in reduced number of bits. Bits reduction occurs to a number that can be completely encapsulated into image. The watermark is randomly encapsulated at the least significant bits (LSBs) of the image without caring of the ROI and RONI to keep the image perceptual degradation negligible. After communication, the watermark is retrieved, decompressed and used for authentication of the whole image, tamper detection, localization and lossless recovery. WITALLOR scheme is capable of any number of tampers detection and recovery at any part of the image. The complete authentic image gives the opportunity to conduct an image based analysis of medical problem without restriction to a fixed ROI.
