Legislation on Space Security: South Korean and Poland Challenges
Polkowska, Malgorzata Korea Society of AirSpace Law and Policy 2019 한국항공우주정책·법학회지 Vol.34 No.1
This article refers to the Space security legislation in South Korea and Poland. Both states have already prepared some legislation on Security in Space- the question is the following- if there is still a need of progress and if those presented legislation are sufficient for the practical purposes of the peaceful uses of Outer Space. South Korea is a much more experienced state in using space than Poland; the same seems with the legislation. Poland as less experienced state in this matter has lots of ambitions to create the efficient legislation on Space security, so it must follow the good examples of states and institution in this matter. One of them is Korea. On the other state, Poland as a Member of EU must implement the European law in space security (in particular SSA), which seems to be priceless and efficient for the international cooperation in Space.

Dogs commonly serve as a model for various human conditions, including periodontal diseases. The aim of this study was to identify the anaerobic bacteria that colonize the subgingival areas in dogs and humans by using rapid real-time polymerase chain reaction (RT-PCR)-based tests and to compare the results obtained in each species. Bacterial microflora evaluations, both quantitative and qualitative, were performed by applying ready-made tests on twelve dogs and twelve humans. Five samples were collected from each subject’s deepest gingival pockets and joined to form a collective sample. The results of the study revealed interspecies similarities in the prevalences of Porphyromonas (P.) gingivalis, Treponema denticola, Tannerella forsythia, and Fusobacterium nucleatum. Red complex bacteria comprised the largest portion of the studied bacterial complexes in all study groups, with P. gingivalis being the most commonly isolated bacterium. The results show similarities in the prevalence of bacterial microflora in dogs and humans. Microbiological analysis of gingival pockets by using rapid real-time PCR-based tests in clinical practice, both veterinary and human, can facilitate the choice of appropriate pharmacological treatment and can provide a basis for subsequent verification of the treatment’s effectiveness.

The purpose of this paper is to examine the microstructural evolution and mechanical properties of Ni/Ti laminatedcomposite produced by a cross-accumulative roll bonding (CARB) method. The SEM images showed that no void anddelamination were observed which indicates that the layers were strongly bonded together. In addition to the thicknessreduction and increased number of interfaces, plastic instabilities took place with an increase in CARB passes; the wavylikeinterfaces appeared as a result of the necking and shear bands formation. However, due to the effect of uniform rollingpressure and rotation of rolling direction during the CARB process, all layers remained continuous in all CARB passes. The most marked observation coming from EBSD analyses was the formation of fine grains surrounded by a high fractionof high-angle grain boundaries (HAGBs). Based on the microtexture analyses on Ti and Ni layers, it was found that byincreasing the rolling passes, a crystallographic texture formed in Ti layers gradually changes from the basic {0001}<112̅0 > system into the system dominated by {0001}<101 ̅0 > prismatic-like orientations. In the case of the crystallographictexture formed in Ni layers, there was a significant increase in the intensity of the Q{013}<231>; P{011}<122 > andGoss {011}<100>, indicating the formation of shear strain-assisted type of texture. Furthermore, with an increase in theCARB passes, the mechanical properties improved due to strong interfaces and grain refinement. The maximum values ofthe yield strength, tensile strength, and elongation reached 842 MPa, 936 MPa, and 7.1% respectively, in the final CARBpass. In addition, ductile fracture mainly occurred on fracture surfaces of Ti and Ni layers even though by increasingpasses, cleavage facets appeared due to strain hardening.
