Traditional slicing techniques make slices through dependence graph and improve the accuracy of slices. However, traditional slicing techniques require many vertices and edges in order to express a data communication link because they are based on static slicing techniques. Therefore the graph becomes very complicated. We propose the representation of a dynamic system dependence graph so as to process the slicing of a software system that is composed of related programs in order to process certain jobs. We also propose programs on efficient slicing algorithm using relations of relative tables in order to compute dynamic slices of a software system. Using a marking table from results of the proposed algorithm can make dynamic system dependence graph for dynamic slice generation. Tracing this graph can generate final slices. We have illustrated our example with C program environment. Consequently, the efficiency of the proposed dynamic system dependence graph technique is also compared with the dependence graph techniques discussed previously. As the results, this is certifying that the dynamic system dependence graph is more efficient in comparison with system dependence graph.

This study examined the impact of trivial baselines obtained from GNSS single-baseline processing into a network adjustment in terms of accuracy and estimated coordinates sets. To this end, depending on the inclusion of the dependent baselines, three different types of experimental GNSS networks were composed and adjusted. The results showed that the networks including the trivial baselines are generally overestimated, but differences in the derived coordinates are limited at the millimeter level. A comparison of the adjusted coordinates with those published by the national geodetic agency showed that results of the network consisting of only the independent baselines are more constant than those of the networks with trivial baselines. Finally, a trivial baseline should be excluded from the GNSS network adjustment with a consideration of the realistic accuracy presentation and data processing burden.

It is very important to analyze online customer reviews, which are small documents of writing opinions or experiences about products or services, for both customers and companies because the customers can get good informations and the companies can establish good marketing strategies. In this paper, we did not propose only dependency network model which is tool for analyzing online customer reviews, but also designed and implemented the system based on the dependency network model. The dependency network model analyzes both subjective and objective sentences, so that it can represent relative importance and relationship between the nouns in the sentences. In the result of implementing, we recognized that relative importance and relationship between the features of products or services, which can not be mined by opinion mining, can be represented by the dependency network model.

In vocabulary recognition systems based on HMM(Hidden Markov Model)s, training process unseen model bring on show a low recognition rate. If recognition vocabulary modify and make an addition then recreated modeling of executed database collected and training sequence on account of bring on additional expenses and take more time. This study suggest efficient context dependent process modeling method using decision tree-based state tying. On study suggest method is reduce recreated of model and it's offered that robustness and accuracy of context dependent acoustic modeling. Also reduce amount of model and offered training process unseen model as concerns context dependent a likely phoneme model has been used unseen model solve the matter. System performance as a result of represent vocabulary dependence recognition rate of 98.01%, vocabulary independence recognition rate of 97.38%.

The representation of a procedural program cannot be applied directly to object oriented program representation consisting of class, object, inheritance, and dynamic binding. Furthermore, preexisting program dependence represented the dependence among statements, but not among variables. That is, it could not solve the problem of which variables make an effect on given variables. Consequently, this study presents the method dependence model representing implementation level information including the dependence among variables in an object oriented program. I also propose implementation-based class testing technique based on the test adequacy criterion of an object-oriented program. Considering inter-data member dependences and a set of axioms for test data adequacy, it generates sequences of methods as test cases which satisfy a flow graph-based testing criterion. For a derived class testing, it considers inheritance relationship and the resuability of the testing information for its parent classes which verified the reduction of test cost through the experiment.

In this paper, the input pattern vectors are extracted and the learning algorithms is designed to recognize EEG pattern vectors. The frequency and amplitude of alpha rhythms and beta rhythms are used to compose the input pattern vectors. And the algorithm for EEG pattern recognition is used SOM to learn initial reference vectors and out-star learning algorithm to determine the class of the output neurons of the subclass layer. The weights of the proposed algorithm which is between the input layer and the subclass layer can be learned to determine initial reference vectors by using SOM algorithm and to learn reference vectors by using LVQ algorithm, and pattern vectors is classified into subclasses by neurons which is being in the subclass layer, and the weights between subclass layer and output layer is learned to classify the classified subclass, which is enclosed a class. To classify the pattern vectors of EEG, the proposed algorithm is simulated with ones of the conventional LVQ, and it was a confirmation that the proposed learning method is more successful classification than the conventional LVQ.

In this paper, we propose an evaluation model of systems level using modified eigenvector method and fuzzy subordination relations. This model is desibmed to evaluate the level of system in enterprise. In here. modified eigenvector method is proposed to compute the weights of each criteria in two evaluation group. Also, fuzzy subordination relations is used to evaluate the relationship between the criteria by painvise comparison. In this paper. we can get the evaluated score for the present level of system. This method will help to manage and improve the systems. We show the efficiency of the this method by means of a case study for evaluation problem of environmental management systems.

자유시장 경제를 신봉하는 사람들은 국가간 교역의 증대는 비교우위에 따른 무역의 증대를 의미하고 이것은 국가간 상호이익을 도모함으로써 세계적인 부를 증진시킨다고 주장한다. 세계화로 다른 나라의 다양한 물품을 우리나라 소비자들이 싼 값에 살 수 있고, 생산자도 세계의 넓은 시장에서 판매활동을 할 수 있으므로 세계적인 부를 증진시킨단 말은 일면 타당해 보인다. 그러나 후진국의 경제발전(특히 수입대체산업의 육성)에 악영향을 미칠 것이며, 선진국 경제에 후진국이 종속되는 결과를 낳을 것이라고 한다. 또한 세계화는 이익을 보는 계층과 손해를 보는 계층을 극명하게 나눠 놓음으로서 분쟁과 갈등을 증대시키는 면도 있다. 예를 들면 최근의 농산물시장의 개방에 따른 우리나라 농민들의 피해, 자본의 대량유입과 대량유출에 따른 외환위기의 위험성 등 개발도상국을 비롯한 중.후진국이 감수해야 할 지도 모르는 부담이 상당하다. 경제적인 종속 이외에도 사회적, 문화적인 종속을 우려하는 시각도 있다. 이러한 가운데 세계화를 주장하는 미국과 대립되는 상황이 나타나는데 이는 자국 문화를 수호하려는 정부의 노력으로 보인다.
