This study investigates key factors affecting the activity of defense technology transfer through the questionnaire survey in Korea. Defense R&D investment has played an important role in promoting the commercial technology development as well as the targeted defense sector through the spin-off mechanism as shown in many countries. Recognizing the importance of effective and efficient investment in defense technology development, the advanced countries in defense technology are trying to establish optimal technology transfer mechanism to maximize the effect of the invested R&D at the national level considering the idiosyncratic features of their own countries. Because the technology transfer mechanisms are very distinct from country to country, it is natural to question "what are the determinants of the effective and efficient technology transfer in Korea?" We tested 19 potential factors and identified 11 factors that are significantly important as the determinants of technology transfer. From the empirical findings, we discuss some policy implications to promote the technology transfer.

This case study aims at investigating the factors which make venture firms successful. It analysedthree high-performance venture firms originated from the government-financed rese arch institute, the company and the university on the viewpoint of 'dynamic capability' theory. In this case study, technology integration capability and administrative innovation capability were identified as success factors of the three venture firms. The study also presented the role of the incubating organizations. Although incubating organizations supported technological and managerial resource-building of the entrepreneurs, there was not active interactive-learning between venture firms and incubating organizations after spin-off.

In this paper, we consider a model problem arising from a classical planar Heisenberg ferromagnetic spin chain $-{\Delta}u+V(x)u-{\frac{u}{\sqrt{1-u^2}}}{\Delta}{\sqrt{1-u^2}}={\lambda}{\mid}u{\mid}^{p-2}u$, x ∈ ℝ^N, where 2 ≤ p < 2^*, N ≥ 3. By the Ekeland variational principle, the cut off technique, the change of variables and the L^∞ estimate, we study the existence of positive solutions. Here, we construct the L^∞ estimate of the solution in an entirely different way. Particularly, all the constants in the expression of this estimate are so well known.

The term research institute spin-offs refers to new firms created by public research institutes. These spin-offs are different from other start-ups in two respects: on the one hand, they should be located in the Special Research and Development Zones and, on the other hand, these firms are supposed to commercialize the results of public R&D activities. These spin-off firms show higher rates of survival and job creation than general new firms, which means that their contribution to economic growth is not negligible. The present study analyzes the factors affecting research institute spin-offs using a random effect panel logit model and negative binomial model. From previous studies, four elements are identified as playing an important role in the commercialization of public R&D through spin-offs, namely their organizational character, research capability, technological character, and geographical location. The empirical results demonstrate that government research institutes with more researchers and patents are more likely to create new firms. In addition, the location of the institutes significantly affects the probability of their creating spin-offs and their number. When the technological stage and TLO size are considered, however, it turns out that the number of researchers and technological stage play important roles in the spin-offs.

The cross-section ratios of the nuclear isomeric pairs $^{80}$ B $r^{m, g}$, sup 81/S $e^{m, g}$, $^{104}$ R $h^{m, g}$, $^{116}$ I $n^{m, g}$ and $^{134}$ C $s^{m, g}$ through the radiative thermal neutron capture process have been studied. The experimental values of these ratios obtained by the activation method have been compared with the calculated ones deduced from the modified Huizenga-Vandenbosch method. Agreement between these values within 30% could be attained by controlling the spin cut-off parameter and gamma-ray multiplicity.

This research focuses on the case studies for operating scheme of technology venture incubation centers located at science parks, technology parks, and foreign universities. Technology venture incubation centers in foreign countries commonly vitalize local economy, create job markets, and promote new venture industry. There is a distinct difference in many ways between foreign and domestic incubation centers. Foreign countries consider the position of incubation centers at national policy level. They characterize the operation of incubation centers into technology fields. They install the networks cooperating with experts and promote the management. Tenant companies moved in incubation centers enhance the degree of completion through industry-university cooperation. Universities and research centers utilize the results of R&D to make the business, accelerate to venture establishment with technical skills, and foster technology entrepreneurs by spin-offs. Through case studies we propose implications helpful to manage domestic technology incubation centers and management methods to be successful centers.

A No Spin Differential (NSD) design has been improved from evaluation of two NSD models utilizing the axiomatic approach. New design parameters of the second level are developed to satisfy the independence axiom. The design matrices are determined to decouple the relationship between design parameters and process parameters. The values of process parameters are then determined to optimize and improve the NSD design. Consequently a unique and evolutionary NSD design is achieved with the aid of the axiomatic approach.

미국의 클린턴 행정부는 풍부한 영상 소프트웨어, 정보통신기술에서의 우위성, 고도의 네트워크를 바탕으로 21세기 정보사회에서의 주도권을 확보하기 위하여 노력하고 있다. 특히 냉전체제의 종식으로 인하여 국방분야에서의 여력이 생긴 연구개발 자원을 민생기술중심으로 전환하고 있으며, 국방분야에서 축적된 기술을 민간으로 확산하는 Spin-off 패러다임이 비판을 받으면서 Spin-on 패러다임을 동시에 구사하는 Dual-use전략을 사용하고 있다. 특히 NII구축을 통하여 다음 세기에서의 국가경쟁력을 강화하고, 국민의 삶을 질을 높이기 위한 노력을 선두적으로 추구하고 있는 상황임을 감안할 때, 미국에서의 정보통신기술정책 및 전략방향을 살펴보는 것은 초고속 기반구축사업을 추진하고 있는 우리 실정에 시사되는 바가 크리라 판단된다. 이를 위해서 미국의 정보통신기술 개발체계와 HPCC(High Performance Cumputing and Communications) 프로그램의 기술개발 현황을 중심으로 정보통신기술개발 동향을 분석하고 정보통신기술에 대한 장기적인 연구개발 방향을 분석하고자 한다.

Recently half-metallic full-Heusler alloy films have attracted significant interests for spintronics devices. As these alloys have been known to have a high spin polarization, very large TMR ratio is expected in magnetic tunnel junctions. Among these alloys, $Co_2MnSi$ full-Heusler alloy with a high spin polarization and a high Curie temperature is considered a good candidate as an electrode material for spintronic devices. In this study, the magnetic and structural properties of $Co_2MnSi$ Heusler alloy films were investigated. TMR characteristics of magnetic tunnel junctions with a $Co_2MnSi/SiO_2/CoFe$ structure were studied. A maximum MR ratio of 39% with $SiO_2$ substrates and 27% with MgO(100) substrates were obtained. The lower MR ratio than expectation is considered due to off-stoichiometry and atomic disorder of $Co_2MnSi$ electrode together with oxidation of the electrode layer.
