지난날 경쟁력과 부가가치 창출의 원천이 토지 노동 자본에서 창출되었다면 오늘날 21세기 지식기반경제에서 새로운 성장의 동력으로 기술이 주목 받고 있다. 이러한 세계경제 패러다임의 변화는 국제적 기술이전의 확산을 가져왔고 국제거래에 있어서 물품과 같은 유형재뿐만 아니라 특허나 노하우 등 대표되는 무형재의 거래도 점차 증가하고 있다. 국제라이선스계약은 기술이전의 대표적 형태로 기술제공자가 기술의 소유권은 그대로 보유한 채로 기술이용자에게 일정기간 기술의 실시만을 허락하고 그 대가로 로열티를 취하는 계약이다. 이러한 기술거래를 통한 경제적 이익은 계약의 원만한 이행과 종료로 실현할 수 있다. 한편 국제라이선스계약은 기술이라는 무형재를 대상으로 하면서 일정기간 대여를 목적으로 한다는 점에서 당사자간 의무가 국제상거래의 대표적 형태인 매매계약과 상이한 부분이 많다. 이에 본고에서는 국제라이선스계약상 당사자의 주요 의무와 각 의무에서 분쟁이 될 수 있는 쟁점을 살펴봄으로써 분쟁의 사전적 예방에 도움이 될 수 있는 시사점을 도출하고자 함을 목적으로 한다.

The technology transfer agreements, which transfer technology from industrialized countries to developing countries, are subjected to control and restrictions in many developing countries in order to protect national interests. The licensors endeavour, therefore, to ensure that their activities fit satisfactorily into the technological policies and plans of the host countries, and contribute to the development of national scientific and technological potential, including the establishment and improvement in host countries of their capacity to innovate. Secondly, the licensors adopt in the course of their business activities practices which permit the rapid diffusion of technologies with due regard to the protection of industrial and intellectual property rights. Thirdly, the licensors endeavour to grant licenses for the use of industrial property rights or to otherwise transfer technology on reasonable terms and conditions.

The inverse heat conduction problems is the calculation of surface heat transfer coefficients by utilizing measured temperature. The numerical technique of finite element analysis and optimizition is introduced to calculate temperatures and heat transfer coefficients. The calculated heat transfer coefficients and temperature distribution are good agreement with the results of direct analysis. The inverse method has been applied to the control valve of nuclear power plant.

In this paper, a semi-analytical method will be discussed for free vibration analysis of rotating beams with variable cross sectional area. For this purpose, the rotating beam is discretized through applying the transfer matrix method and assumed the axial force is constant for each element. Then, the transfer matrix is derived based on Euler-Bernoulli's beam differential equation and applying boundary conditions. In the following, the frequencies of the rotating beam with constant and variable cross sections are determined using the transfer matrix method in several case studies. In order to eliminate numerical difficulties in the transfer matrix method, the Riccati transfer matrix is employed for high rotation speed and high modes. The results are compared with the results of the finite elements method and Rayleigh-Ritz method which show good agreement in spite of low computational cost.

In this rapidly changing knowledge-based society, technology is regarded as one of critical factors for competitive edge and sustainable growth. Therefore, most of countries in the world have strengthened their efforts to promote industrial technology innovation and development. In Korea, KIAT(Korea Institute for Advancement of Technology) newly established m May 2009 as a quasi-government institute with the integration of six organizations including KTTC(Korea Technology Transfer Center) has played a crucial role in transferring and commercializing industrial technologies between public and private sectors. Generally, technology transfer and commercialization have been conducted by the contracts which are very detailed, complex and diverse. To solve any disputes and controversies between the parties, it is essential to make a prior agreement on the amicable settlement by the use of Arbitration Clause. By reviewing the characteristics, process, current situation and model contracts of domestic technology transfer in Korea, it is quite recommend for arbitration-related organizations such as KCAB(Korean Commercial Arbitration Board) to foster the strong campaign for the popular use of Arbitration Clause. It will contribute to settle any disputes and controversies between the parties more speedy, economically and rationally, thereby promoting the technology transfer and commercialization in Korea.

A basic heat flow model has been developed to estimate the heat transfer coefficient at the casting/mold interface during squeeze casting. Based on the measured temperature profiles in squeeze casting of Al-4.5%Si alloy, heat transfer coefficients which vary with time were calculated by numerical method. The influences of the load and the amount of fraction solid on the heat transfer coefficient have also been studied. Using the calculated heat transfer coefficient two dimensional solidification analysis in the squeeze casting process was carried out by the finite difference method, and the results were in good agreement with the experiments. It may be concluded that heat flow analysis in the squeeze casting process with accurate heat transfer coefficient at the casting /mold interface is important for a proper design of cooling in die and finally for improving productivity and die life as well.

Stability is impaired in capsules in which there is a transfer of water vapor from capsule to the contents of the capsules. The water vapor transfer between AEA-coated capsules and corn starch, magnesium trisilicate in the closed container was examined. Experimental eguilibrium relative humidity after water vapor transfer and estimated values calculated from a formula of these substances were in close agreement with each other.

It is important to completely understand heat/mass transfer from a flat plate because it is a basic element of heat/mass transfer. In the present study, local heat/mass transfer coefficient is obtained for two flow conditions to investigate the effect of boundary layer using the naphthalene sublimation technique. Obtained local heat/mass transfer coefficient is converted to dimensionless parameters such as Sherwood number, Stanton number and Colburn j-factor. These also are compared with correlations of laminar and turbulent heat/mass transfer from a flat plate. According to experimental results, local Sherwood number and local Stanton number are in much better agreement with the correlation of turbulent region rather than laminar region, which means analogy between heat/mass transfer and momentum transfer is more suitable for turbulent boundary layer. But average Sherwood number and average Colburn j-factor representing analogy between heat/mass transfer and momentum transfer are consistent with the correlation of laminar boundary layer as well as turbulent boundary layer.

This study presents an idea of using analogy concept to the heat transfer studies regarding the HTGR development. Theoretical backgrounds regarding the idea were reviewed. In order to investigate the predictability of a mass transfer system for heat transfer system phenomenology, an electroplating system coupled with a limiting current technique was adopted. Test facilities for laminar forced convection and natural convections under laminar and turbulent conditions were constructed, for which heat transfer correlations are known. The test results showed a close agreement between mass transfer and heat transfer systems, which is an encouraging indication of the validity of the analogy theory and the experimental methodology adopted. This paper shows the potential of the experimental method that validates the little-understood heat transfer phenomena, even in complex geometries such as HTGR.

Heat treatment is one of the critical manufacturing processes that determine the quality of a product. This paper presents experimental and analytical results for the quench of a ring gear in stagnant oil. The goal of this study is to develop heat transfer predicting model in an overall analysis of the quenching process. Thermal conductivities which are dependant on temperatures and convection coefficients which are obtained by inverse method are used to develop the accurate heat transfer model. The results of heat transfer model have a good agreement with experimental results.
