The rapid development of the internet may not have occurred without techniques of linking and framing, which provide users flexible and easy access to other website. These techniques have enabled internet users to navigate the internet efficiently and sort through the products, services and information available on the internet. The Advent of the global information structure and the do-called EC revolution raise countless new issues and questions. There are no limitations regulating the expressions on the cyberspace due to internet's of quality anonymity? diversity? spontaneity. Therefore, the freedom of speech is expanded in both areas of time and space, which was impossible with the old communicating system. Although online technology raises many new legal issues, the law available to help us resolve them, at least today, is largely based on the world as it existed before online commerce became a reality. Thus the challenge is to predict how these new legal issues may be resolved using the current law. As a result of the drastic change of the environment for international trade of which that has taken took place in parallel with the global information technology revolution on a global basis, the scope of issues to be addressed which should be resolved by the conflict of laws principles has been remarkably expanded, and various new issues of an entirely which are quite new in its type and nature have arisen been raised. Further more in addition, the old act prior act was regarded as insufficient in that it lacked rules on international governing law to adjudicate, or international adjudicatory governing law, where as the expectation of the public was that the private international law should function as the basic law of the legal relational encompassing rules on governing law given the increase of It international disputes. for the move the private international law has also attracted more attention from the korean.

The aim of the study was to investigate the seroprevalence of equine herpesvirus type 1 (EHV-1) and type 4 (EHV-4), equine influenza virus (EIV), and Streptococcus (S.) equi subspecies equi in the horse population of Jeju. Serum samples were taken from 71 horses, regularly vaccinated with EHV-1 and strangles twice (April and November) a year. In April 2014, seropositive rates of EHV-1 and strangles were 24.5% and 84.5%, while in November, were 26.8% and 62.0%, respectively. A total of 1,144 serum samples, including Jeju native horses, Halla horses, and Thoroughbred horses were collected from slaughter house for 4 years (2014 to 2017) and it is unclear the animals were vaccinated or not. The seropositive rates in Jeju was 21.9% (250/l,144) for EHV-1, 96.4% (1,103/1,144) for EHV-4, 14.6% (129/882) for EIV, and 79.3% (879/1,108) for strangles. The seropositive rate was the highest in Thoroughbred, but lowest in Hala horse.

This paper discusses to what extent the party autonomy can be allowed in intellectual property dispute resolution agreements in determination of governing law, international jurisdiction, and ADR agreement for arbitration, etc. in considering of the territoriality principle of IP. The party autonomy in choice of governing law and jurisdiction can be fully enjoyed in IP contract disputes. However, the freedom of choice is limited to the disputes regarding IF infringement disputes. The party autonomy is denied in the issues of determination of validity of patent or other IP rights. The author seeks the possibility to allow as much freedom in making choice of applicable law or jurisdiction, or entering into arbitration agreement.

In the present work the second-order perturbation solutions of the simple physical model for liquid pool spreading is obtained for the case of instantaneous spill. To generalize the solution governing equations are non-dimensionalized, and two dimensionless parameters, dimensionless evaporation rate and aspect ratio of the initial pool, are identified to control the governing equations. The dimensional governing equations have three parameters. The second-order solution improves fairly the first-order solution for the pool volume.

This paper presents a maneuver analysis of a full-vehicle featuring electrorheological (ER) suspension and ER brake. In order to achieve this goal, an ER damper and an ER valve pressure modulator are devised to construct ER suspension and ER brake systems, respectively. After formulating the governing equations of the ER damper and ER valve pressure modulator, they are designed and manufactured for a middle-sized passenger vehicle, and their field-dependent characteristics are experimentally evaluated. The governing equation of motion for the full-vehicle is then established and integrated with the governing equations of the ER suspension and ER brake. Subsequently, a sky-hook controller for the ER suspension and a sliding mode controller for the ER brake are formulated and implemented. Control performances such as vertical displacement and braking distance of vehicle are evaluated under various driving conditions through computer simulations.

The governing equations of wave propagation in one dimension of elastic continuum materials are investigated by taking the influence of the initial stress into account. After a short review of the theory of elastic wave propagation in a rock mass with an initial stress, results indicate that the initial stress differentially influences P-wave and S-wave propagation. For example, when the initial stress is homogeneous, for the P-wave, the initial stress only affects the magnitude of the elastic coefficients, but for the S-wave, the initial stress not only influences the elastic coefficients but also changes the governing equation of wave propagation. In addition, the P-wave and S-wave velocities were measured for granite samples at a low initial stress state; the results indicate that the seismic velocities increase with the initial stress. The analysis of the previous data of seismic velocities and elastic coefficients in rocks under ultra-high hydrostatic initial stress are also investigated.

We have derived the general transfer equation for governing the continuity, energy transfer, mass and momentum transfer, and turbulent energy dissipation rate within the fire compartment which has the 800t fire source at the center of the floor. The governing transfer equations have been descretized using the finite volume approach and numerically experimented under the SIMPLE algorithm. In order for the SIMPLE algorithm approach to be physically reliable, the test results are compared with those of Morita's SOR Method using Conjugate Residual Method and found to be close to physical values though the computational convergence time still remains to be upgraded. The treatment of source terms in the system of finite difference equations has been critical in order to converge the governing equations within the appropriate time steps. The criteria of convergence allowance for the whole domain have been checked and the sudden change of the non-linear effects from the source term have been avoided. The criteria has been allowed to be for 5$\times$10$^{-5}$ .

Unsteady groundwater flow in a three-layer unconfined aquifer has been studied theoretically and experimentally. Two different methods have been used in solving the governing equations of the flow, the nonlinear partial differential equations; (1) The governing equations are linearized for each layer and approximate solutions are obtained. (2) The governing equations are transformed to nonlinear ordinary differential equations, which are solved numerically by Runge-Kutta procedure. Fine, middle sized and coarse sands are used in the experiments. It is found that the solutions from the method(2) ( the reduction of partial differential equations to ordinary differential equations) give better agreement with the experimental results than the solution from the method(1).

Modern electric controlled valves are demanded that its solenoid actuator should be smaller size, lighter weight, lower consumption power, and higher response time. For achieving these purposes, the major design factors of solenoid actuator such as magnetic flux density, coil turn numbers, plunger size, bobbin dimension, and etc. are must be optimized. In this study, for optimal design of high speed solenoid actuator for hydraulic servo valve operation, we draw up governing equations which are composed by combination of electromagnetic theories and empirical knowledge, and deduct the values of major design factors by use of them. For more increase the operating speed, voice coil are used as main armature in manufacturing of prototype actuator. And, we have proven the propriety of the governing equations and speed increasing method by experiments using the hydraulic valve assembly adopted the prototype of solenoid actuator.
