To build autonomous agents who can make a decision on behalf of humans in time-critical complex environments, the formulation of operational knowledge base could be essential. This paper proposes the methodology of how to formulate the knowledge base and evaluates it in a practical application domain. We analyze threat data received from the multiple sensors of Aircraft Survivability Equipment(ASE) for Korean helicopters, and integrate the threat data into the inductive model through compilation technique which extracts features of the threat data and relations among them. The compiled protocols of state-action rules can be implemented as the brain of the ASE. They can reduce the amounts of reasoning, and endow the autonomous agents with reactivity and flexibility. We report experimental results that demonstrate the distinctive and predictive patterns of threats in simulated battlefield settings, and show the potential of compilation methods for the successful detection of threat systems.

The purpose of this study is to diagnose problems of the permanent judge system by examining the cases of practical running of the permanent judge system, and to provide basic materials for the settlement of fair and transparent judge culture. The findings of the case studies are as follows. First, the difficulties in selection, allocation, and education of judges caused by the operation of the permanent judge system. The problems in allocation are forceful allocation, conflict over allocation with general judges. The problems in evaluation are individual evaluation and limits of fairness, lack of evaluation rules. Second, the unpredictability of whether the permanent judge system survive or not. Third, there are some environmental constraints of the permanent judge system. Lack of protective apparatus is lack of rescue method and solution for intentional protest. Forth, there is a problem of low recognition of the permanent judge system. As the federation has been not active in publicizing the permanent judge system, the system is not well known.

According to the dispostions of 1967 Space Treaty, the contracting states should assume legal obligation to assure an authorization and continuing supervision with regard to the national space activities. Any space activities have to abide by the rules of international law as well as specified obligations set by the Treaty. Among several treaty obligations, International responsibility to be bome by the state, and the liability principles are deemed as major outstanding obligations which the state should takeinto account. While nation's first launch site is to be operational in a few years, korean government should assure that its national space activities, such as launching of space object, operation of satellites, etc. should be under governmental authorization and supervision. A legislative effort would be most desirable undertaking for this regard. Especially a specific legislation needs tobe studied forwith such authorization regime so that international responsibilty and the liability as to thelaunching of space object should be under the regulatory scheme. This study focuses upon the necessity of such legislation and proposes some major items and framework for the legislation

MIB(Management Information Base), one of the key components of network management system, is a conceptual repository for the information of the various managed objects. MIB stores and manages all the structural and operational data of each managed resources. Therefore, MIB should be protected properly from inadvertant user access or malicious attacks. International standard ISO/IEC 10164-9 describes several managed object classes for the enforcement of MIB security. Those managed object classes described access control rules for security policy. But the exact authorization procedures using those newly added managed object classes are not presented. In this paper, we divide managed object classes into two groups, explicit and implicit ones, and describe the access authorization procedure in Z specification language. Using Z as a description method for both authorization procedure and GDMO's action part, the behaviour of each managed object class and access authorization procedure is more precisely and formally defined than those of natural language form.

In this paper, we proposed a new circuit construction method that reduced the number of CMOS devices of singleton fuzzy controller(SFC) through the proposing a new membership function circuit(MFC) which uses the language variable selecting and the coefficient selecting circuit. According to the range of input values, we can choose the language variables beforehand which will be used in the inference. So we proposed the new MFC which generates the only necessary language variables. Also, we removed all rules of which adapting degree of their antecedents is zero through proposing the coefficient selecting circuit which beforehand selects the coefficients which will influence the inference result. Though this method, we simplified the structure of SFC and reduced the size of hardware. And to solve the problem in the current mode with respect to the restriction of the fan-out number, voltage-input and current-out membership function circuits are constituted of operational transconductance amplifiers. A membership function circuit which includes the language variable selecting circuit, a minimum operation circuit we implemented by current mode CMOS devices. As a result of applying proposed method, total numbers of blocks and devices wave decreased. If the number of variables and antecedents are getting larger, this method is more efficient.

A remarshalling is studied as an important operational strategy in an automated container terminal to enhance the productivity of container handling. This means the rearrangements of the containers scattered at a vertical yard block. The dispatching problem for remarshalling is selecting the remarshalling operation considering the available operation time and deciding the operation sequencing to maximize the effectiveness of remarshalling. This study develops the optimal mathematical model for yard crane dispatching problem with mixed integer program and explains dispatching problem using an example. However it is difficult to apply this model to a field problem because of its computational time. Therefore, we compare the representative 5 dispatching rules for real world adaption. In a numerical experiment, maximum weight ratio(MR) rule shows an overall outstanding performance.

In this paper, we propose military symbols for cyber operations to understand the situation in cyberspace intuitively. Currently, standardized military symbols are mainly for kinetic operations, and they do not consider cyber operations. Although, MIL-STD-2525D includes some symbols for cyber operations, only icons that are composed of three letters are standardized. So there is a limit to effectively expressing cyber operations. That is why we propose military symbols for cyber operations compatible with existing military symbol building rules. In addition to merely presenting the symbols, we present examples of expressing various cyber situations using the proposed symbols. It proves the usefulness of the proposed symbol. The small number of symbols proposed in this paper will not be able to represent all cyber situations. However, based on the proposed symbols, it is expected that more symbols will be standardized in the future to more clearly express the cyber situation.

Major IT vendors expect that cloud computing technology makes it possible to reduce the contents service cycle, speed up application deployment and skip the installation process, reducing operational costs, proactive management etc. However, cloud computing environment for massive content service solutions requires high-performance data processing to reduce the time of data processing and analysis. In this study, Efficient_Cloud_Processing_Scheme(ECPS) is proposed for allocation of resources for massive content services. For high-performance services, optimized resource allocation plan is presented using MapReduce programming techniques and association rules that is used to detect hidden patterns in data mining, based on levels of Hadoop platform(Infrastructure as a service). The proposed ECPS has brought more than 20% improvement in performance and speed compared to the traditional methods.
