The Ministry of Education. Science and Technology had revised the 'The professional Engineers Act' in 2007 in order to enhance the efficiency of the professional engineers. The Ministry also had adopted "The International Professional Engineer Registration System which included APEC engineer and EMF international professional engineer and has worked on various MRA of professional engineer and has worked on various MRA of professional engineers through FTA with USA, Singapore. EU, Canada and Australia etc. The Ministry will participate in the negotiation meeting For MRA of professional engineers with Singapore in coming November and also will negotiate positively MRA of professional engineers with USA upon the ratification of National Assembly.

The wide spread of DC electric railway systems such as urban rapid transits including heavy rail and light rail transits has significant ramification as the stray currents from return conductor rails can cause the electrochemical interference, that is, the electrolytic corrosion of both rails and outside underground metallic infrastructures. The immature understanding of either the railway authority who is responsible for establishing the necessary provisions at the design stage or the affected parties makes it difficult to prepare the optimum range of solutions for the long-pending interference problem. In advanced countries, however, numerous assessment studies have been carried out on the stray current interference, by which protective standards and regulations are provided under the collaboration and agreement of the related parties. In this paper, we introduce a european standard from IEC, namely, "IEC 62128-2:2003 railway applications-fixed installations -part 2: protective provisions against the effects of stray currents caused by d.c. traction systems" and a "Code of Practice" produced by Victorian electrolysis committee (VEC) based on "Electricity Safety Act 1998" and "Electricity safety (stray current corrosion) regulations 1999" of Victoria state, Australia.

Transformation behavior of rapidly solidified Ti-47.3Ni (at%) alloy ribbons and thermal stability of the R phase in the ribbons were investigated by means of differential scanning calorimetry (DSC), X-ray diffraction, and transmission electron microscopy. Rapidly solidified Ti-47.3Ni alloy ribbons showed the two-stage B2-R-B19' martensitic transformation behavior. The B2-R transformation in the ribbons was observed even after annealing at 1,223 K, which was attributed to the fact that a specific orientation relationship between $Ti_2Ni$ and matrix in the ribbons is maintained after annealing at 1,223 K. The DSC peak temperature of the B2-R transformation ($T_R^*$) decreased with raising annealing temperature, which was attributed to the increased volume fraction of $Ti_2Ni$, thus causing an increased Ni content in the matrix.

This paper addresses on new codes of practice, limit state design; load resistance factored design and Eurocode 7, which have recently been adopted by foundation engineers in North America and European Communities. A brief description of the limit state design concepts and some introductions to Australia and Sweden national code for pile foundation are made on behalf of pile capacity determination. Also, simple closed form solution for rational resistance factor when resistance is log-normally distributed, has been derived for pile foundation.

Generally, there are two types of regulation strategies for encouraging renewable energies ; regulation by quantity and price. With examples of quantity regulation, there RPS (Renewable portfolio standard) system in United States America, Renewable obligation in England, and MRET system in Australia. Countries that chose the price regulation are Germany, Spain, France, Portugal. This Paper overviews the current trends of regulation system on policies for renewable energies in foreign countries on these days.

In knowledge based society of 21c, engineers require not only their own speciality but also engineering basic competency such as creative thinking, the ability of working together, the ability of communication. Engineering colleges responsible for educating engineers consider developing curriculum including Engineering Basic Competency which is reflecting the needs of the times. By utilizing the accreditation programs of engineering education, UK-SPEC of UK Engineering Council, EA(Engineering Australia) standards/handbook of the Institute of Engineers Australia, O*NET of U.S. Occupational Network, this study generates core elements of engineering basic competency to prove the capability of engineering basic competency required to desired engineers. Core constituents derived from the study were categorized into 3 major areas of the basic engineering literacy in Humanities and Social Sciences(HSS), the ability of Creativity Engineering Design, Career development and each category and constituents were surveyed and checked by engineers in the field to deduce engineering basic competency that should be educated in the engineering college.

This study was conducted to estimate the design flood by the determination of best fitting order of LH-moments of the annual maximum series at six and nine watersheds in Korea and Australia, respectively. Adequacy for flood flow data was confirmed by the tests of independence, homogeneity, and outliers. Gumbel (GUM), Generalized Extreme Value (GEV), Generalized Pareto (GPA), and Generalized Logistic (GLO) distributions were applied to get the best fitting frequency distribution for flood flow data. Theoretical bases of L, L1, L2, L3 and L4-moments were derived to estimate the parameters of 4 distributions. L, L1, L2, L3 and L4-moment ratio diagrams (LH-moments ratio diagram) were developed in this study.

Ground test of model Scramjet engine was performed with T4 free-piston shock tunnel at University of Queensland, Australia. Test condition of free stream was Mach 7.6 at 31 km altitude. With this condition, variation effects of fuel equivalence ratio, cavity, cowl setting were investigated. In the results, supersonic combustion or thermal choking was observed depending on the amount of fuel. Cavity and W-shape cowl showed early ignition and enhanced mixing respectively.

Korea Aerospace Research Institute(KARI) made a scramjet engine test contract with the University of Queensland in October 2006. The experiments were conducted at Mach 7.6, Altitude 31.2 km condition in the T4 free piston-driven shock tunnel in June 2007. In this paper, the short introduction and data processing technique of the T4 free piston-driven shock tunnel will be explained.
