Along with the developing of mobile communication technology, plenty of data transmission turn into possible in mobile environment. As the foundation, it can provide diverse mobile service. Especially the service which use electronic signature, and as the transmission of XML technology among the terminal digital signature information. By now, allowed plenty of validity confirmation questions that the digital signatures about the characteristic induced application of physical property XML. For this question, it can be solved through XML by Canonical XML 1.0 standards provided in W3C. But, because the question in the XML namespace attribute inheritance, proposed the restrictive solution. In order to solve this problem, proposes candidate plan of Canonical XML 1.1 standardized in W3C, and also even more standardization. In this paper, in order to support the widespread XML standardization in the moving environment. Standardizes Canonical XML 1.1 standard as the underlies, safeguarding the theoretical mutual identity of the XML documents, and constructing and realizing the XML standardization system.

Game object inheritance and multiple components allow for visualization of system architecture, good code reuse, and fast prototyping. On the other hand, objects are more likely to rely on high latency between game objects and components, static casts, and lots of references to things like null pointers. Therefore, It is important to design a game in such a way so that the dependency of objects on multiple classes could be reduced and existing codes could be reused. Therefore, we designed the game to make the classes more modular by applying Dependency Injection and the design patterns proposed by the Gang of Four. Since these dependencies are attributes of the game object and the injection occurs only in the initialization pass, there is little performance degradation or performance penalty in the game loop. Therefore, this paper proposed an efficient design method to effectively reuse APIs in the design and implementation of survival games.

The Weapon Target Allocation(WTA) problem is the NP-Complete problem. The WTA problem is that the threatful air targets are assigned by weapon of allies for killing the targets. A good solution of NP-complete problem is heuristic algorithms. Genetic algorithms are commonly used heuristic for global optimization, and it is good solution on the diverse problem domain. But there has been very little research done on the generation of their initial population. The initialization of population is one of the GA step, and it decide to initial value of individuals. In this paper, we propose to the population initialization method to improve a Genetic Algorithm. When it initializes population, the proposed algorithm reflects the characteristics of the WTA problem domain, and inherits the dominant gene. In addition, the search space widely spread in the problem space to find efficiently the good quality solution. In this paper, the proposed algorithm to verify performance examine that an analysis of various properties and the experimental results by analyzing the performance compare to other algorithms. The proposed algorithm compared to the other initialization methods and a general genetic algorithm. As a result, the proposed algorithm showed better performance in WTA problem than the other algorithms. In particular, the proposed algorithm is a good way to apply to the variety of situation WTA problem domain, because the proposed algorithm can be applied flexibly to WTA problem by the adjustment of RMI.
