The defense industry export of Korea has been steadily risen since 2006. It is attained $340million, the highest export amounts ever, in 2013. As the defense industry export increase, Defense Acquisition Program Administration (DAPA) built defense industry export and import management system to assist export and to protect defense technologies. In this paper, we study factors to activate the defense industry export and import management system using Technology Acceptance Model(TAM) in compulsive usage environment. The significance of this study is as follows: First, we prove the reliability and feasibility of measurement variables in defense industry of compulsive usage environment. Second, we suggest factors to activate the defense industry export and import management system. Third, we present methodology to find factors in computation systems of public institute using TAM.

We write down explicity a recursive formula of one-pointed gravitational Gromov-Witten invariants and reduce the computation of them to a combinatoric problem which is not solved yet. The one-pointed invariants were played important role in Givental’s program in mirror symmetry. In section 3, we describe the combinatoric problem which can be read independently.

This paper presents the iterative procedure with the concept of expanded waves in the spectral and spatial domains using the fast modal algorithm. We presents its applications to microwave integrated circuits on resistive substrate. The advantage is a reduction in computation time. These calculated results are checked by comparison with the experimental and simulated results by Sonnet and Momentum program.

In this paper, we propose a new method to parallelize multidimensional subscript loop with non-uniform distance. A loop comprise most of the computation in a program and the most important source of parallelism. Multidimensional subscript within a loop difficult to determine for distance to be required loop dependence Elimination. Therefore we Propose new methods that is three algorithm to search subscript.

The problem of finding shortest paths between every pair of points in a network is solved employing and optimal network decomposition in which the network is decomposed into a number of subnetworks minimizing the number of cut-set between them while each subnetwork is constrained by a size limit. Shortest path computations are performed on individual subnetworks, and the solutions are recomposed to obtain the solution of the original network. The method when applied to large scale networks significantly reduces core requirement and computation time. This is demonstrated by developing a computer program based on the method and applying it to 30-vertex, 160-vertex, and 273-vertex networks.

The Bayesian nonparametric estimation of two uniformly stochastically ordered distributions is studied. We propose a restricted Dirichlet Process. Among many types of restriction we consider only uniformly stochastic ordering in this paper since the computation of integrals is relatively easy. An explicit expression of the posterior distribution is given. When square loss function is used the posterior distribution can be obtained by easy integration using some computer program such as Mathematica.

농업기계 이용비용 절감을 위해서는 영농규모와 사용목적에 맞는 적절한 규격의 농업기계를 선택하여 사용하는 것이 필요하나 농업기계의 선택과 관련하여 농업인이 참고할 만한 자료가 미흡한 실정이다. 이에 따라 농업기계의 기종별, 규격별로 경제적으로 이용 가능한 규모와 소요비용에 대해 농업인이 쉽게 이용할 수 있는 자료의 개발, 보급이 필요한 실정이다. 따라서, 본 연구에서는 농업인이 농업기계의 경제적 이용규모와 소요비용 등을 시산 할 수 있는 프로그램을 개발하고, 이 프로그램을 이용하여 부담면적과 기계이용비용, 손익분기 규모를 시산 하였다.

In this study. an experiment has been performed to investigate distributions of static pressure around a circular cylinder in a uniform shear flow which is made by a specially designed wind tunnel. From the computation program(BLAYER), various boundary layer value are obtained depending on the shear flow rate. It is basical design data that boundary layer flow phenomenon of nuclear power plant heat exchanger tube surroundings. airfoil. and others flow fields.

Stability aspects have often been incorporated in the dispatch/pricing procedure using trial and error methods, or approximated in the dispatch optimization directly as a set of linear constraints on generation/transmission. This paper presents introduction of PSS/OPF and voltage instability analysis using the program. Additional advantages offered by FSS/OPF are easier procedures, less computation and avoidance of engineering judgement in identifying the amount of shunt requrement at the candidate buses.

In this paper, we describe a method for fuzzy polynomial regression analysis for fuzzy input-output data using shape preserving operations based on Tanaka’s approach. Shape preserving operations simplifies the computation of fuzzy arithmetic operations. We derive the solution using general linear program.
