The passing of property in goods affects contractual rights and duties. It is the point on which depend issues as diverse as the seller's entitlement to sue for the price and the incidence of risk of loss of casualty to the goods. The passing of property may also have an incidental effect on the remedies of the parties, including specific performance. But Incoterms do not deal with how the goods should reach the agreed point of delivery. While Incoterms specifically deal with questions of division of risk of loss of or damage to the goods between seller and buyer, they do not deal with property or transfer of title of the goods. Indeed, it was not even possible to agree on uniform rules on these questions in the CISG. Therefore, the parties to a contract of sale should provide for these matters themselves in the contract of sale and closely observe what the applicable law requires for the transfer of ownership to the goods and other property rights.

This study is to characterize the material property of early age high performance concrete emphasizing compressive strength using nondestructive testing methods. Three high performance concrete slabs of 600, 850 and 1100kg/$cm^{2}$ compressive strengths were prepared together with cylinders from same batches. Cylinder tests were peformed at the ages of 7, 14, 21 and 28 days after pouring. Using the impact echo method, the compression wave velocities were obtained based on different high performance concrete ages and compressive strengths. The equation to obtain the compressive strengths of high performance concrete has been developed using the obtained compression wave velocities. Using the SASW (spectral analysis of surface wave) method, the equation have also been developed to obtain the compressive strengths of high performance concrete based on the surface wave velocities.

The assessment of fatigue property is one of the most indispensable factors to design mechanical structures or parts. For accurately assessing fatigue property, it is necessary to precisely identify the loading condition and material property of the objective structure. However, there are many kind of problems in conducting predictive activity for a design concerned with variable factor such as fatigue phenomenons and environments. Therefore, most of the fatigue problems have been assessed from exiting experiment data and prediction method. In this study, expert system is developed for simply conducting performance assessment of weldments based on Finite element Analysis carrying out performance improvement and safety assessment of welded structures.

This paper presents the property of the Squeeze Film Damper (SFD) using Magneto-Rheological fluid (MR fluid). The damping property of a SFD for a flexible rotor system varied according to vibration mode. MR fluid is known as a functional fluid with controllable apparent viscosity of the fluid by applied magnetic field strength. When the MR fluid is applied in the SFD, the SFD using MR fluid can effectively reduce vibrations of the flexible rotor in a wide range of rotating speed by control of the applied magnetic field strength. To investigate in detail the SFD using MR fluid, the SFD to support one mass was constructed and its performance was experimentally investigated in the present study. The damping property of the SFD using MR fluid has viscous damping by Newtonian fluid, but not Coulomb friction by Bingham fluid. Therefore, The system damped by the SFD can be considered as a linear system.

Nanofiltration of aqueous dye solutions was carried out using polyamide (PA) nanofiltration (NF) composite membranes. The PA composite membranes were prepared by the interfacial polymerization of piperazine (PIP) and trimesoyl chloride (TMC) on the surface of microporous polysulfone (PSf) ultrafi1tration (UF) membranes. After characterization in terms of their permeation performance and surface ionic property, they were used for the separation of dye solutions such as Direct Red 75, 80, 81, and Direct Yellow 8 and 27. The separation conditions were varied to study the factors affecting on the permeation performance of the membranes: different concentrations of dye solutions, operating temperature and time, and flow rate of a feed solution. The surface property of the membrane, especially its ionic property, as a function of operating time was examined with a zeta-potentiometer and the relationship between the surface chemistry of the membrane and its permeation properties was also studied.

Since a declaration between North and South Korea was adopted, North and South Korea has strengthened the interchange and cooperation between each other in many fields. Especially, the interchange and cooperation in the field of industrial property right, such as patent and trademark, are required to keep up with the age of the knowledge industry. But, until a recent date, there has been little interchange or cooperation in the field of industrial property right, and a few major companies were attempt to apply for the patent in North Korea through the Third country The system of industrial property laws in North and South Korea are very different because of time and political ideology barriers. To unify the system of industrial property laws in North and South Korea, firstly, North and South Korea must try to recognize and understand the dissimilarity between them. In this article, I compared the system of industrial property law of South Korea with that of North Korea to search commonalities and dissimilarities. Furthermore, it is needed to establish systematic devices for understanding of between North and South Korea, for instance, conducting a interdisciplinary seminar or dispatching a judge mutually. Finally, it is necessary to phase in a practical plan for unification. In the short run, mutual application and registration have to be authorized, and in the long view, unifying the practice of industrial property law service is needed. At the conclusion, the industrial property laws in North and South Korea can be unified systematically. In other words , to unify system of industrial property laws in North and South Korea, it is prerequisite that mutual understanding of industrial property laws and performance of the unify plan. The interchange and cooperation in this field will not only promote technical development but also create common interests of North and South Korea by expanding an opportunity for creating and utilizing industrial property.

Owing to advantages of polymeric materials for hydrogen tank liner like light-weight property and high specific strength, polymer based composites have gained much attention. Despite of many benefits, polymeric materials for fuel cell tank cause problems which is critical to applications as low gas barrier property, and poor processability when adding fillers. For these reasons, improving gas barrier property of polymer composites is required to study for expanding application fields. This work presents impermeable polymer nanocomposites by introducing thin barrier coating using layer by layer (LBL) deposition method. Also, bi-layered and quad-layered nanocomposites were fabricated and compared for identifying relationship between deposition step and gas barrier property. Reduction in gas permeability was observed without interrupting mechanical property and processability. It is discussed that proper coating conditions were suggested when different coating materials and deposition steps were applied. We investigated morphology, gas barrier property and mechanical properties of fabricated nanocomposites by FE-SEM, Oxygen permeation analyzer, UTM, respectively. In addition, we revealed the mechanism of barrier performance of LBL coating using materials which have high aspect ratio.
