Since Civil Law recognizes the freedom of a testament, it recognizes the freedom allowing the decedent to dispose his/her own property at his/her own intention. However, in order to prevent various abuses which may occur when the principle of freedom of testament is carried out unlimited, secured portion system is stipulated. So, absolute freedom of property disposed by the deceased is limited. Likewise, the secured portion system is introduced as the system to resolve the contradiction that exists between principle of freedom of testament and legal inheritance. Since Supreme Court Decision 2010DA50809 delivered on May 24, 2012 includes major legal issues such as how to exercise of claim of return for secured portions, transfer of the secured proportion or the claim of return for secured portions, and exercise of claim of return for secured portions against a third party. So, it has a very important meaning. In this paper, legal issues regarding the exercise of claim of return for secured portions have been reviewed with this decision.

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.
