저비용, 네트워크화 된 센서들, 언제 어디서나 쉬운 인터넷 사용과 같은 컴퓨팅 환경의 진화는 우리의 일상생활 속으로 진정한 모바일 환경을 실현 가능하게 만든다. 이런 모바일 환경의 발달은 다양한 모바일 에이전트들을 양산하며 사용자의 편의를 극대화 할 수 있도록 한다. 모바일 에이전트들은 사용자 정보, 주변 환경정보, 컴퓨팅 정보 또는 애플리케이션 정보 등을 XML 기반 표준 언어인 ACML(Agent Communication Markup Language)로 저장한 후 상호교환 및 분석을 하게 된다. 기존 테이블 형태의 정보를 기반으로 사용자의 행동패턴을 분석 및 예측했던 시스템과는 달리 에이전트 환경에서의 사용자 행동패턴 분석 및 예측은 트리구조를 대상으로 하기 때문에 새로운 방법이 요구된다. 본 논문에서 제안한 기법은 XML 기반 표준 언어인 ACML로 저장된 정보를 사용자의 상황(context)에 적합하도록 고려하여 언제, 어디서나 원하는 정보를 자동적으로 사용자에게 제공할 수 있도록 한다.

Mobile device will be able to use the various contents from the advancement of the wireless Internet and mobile device manufacture technique. Each devices HTTP headers about under using provides terminal information to contents provider which is provided the contents which is suitable in device. But there is not a standard for a terminal information proηsion and when using the contents of service network outside, interoperability problems mobile communication it will provides terminal information in different method. International Organization for Standard OMA UAProf about under using it solved interoperability problems from outside. But about under using it provides terminal information, MMS support and Smart Card support, against an external storage space supporting information it is not seen clearly UAProf not to be, it will not be able to provide terminal information which is complete. This paper hereupon it designed UAProf in base which provides the contents which has become optimize to the mobile device of domestic environment the mobile device description language which expresses device information which is necessary.

IPsec offers not odd Internet security service such as Internet secure communication and authentication but also the safe key exchange and anti-replay attack mechanism. Recently IPsec is implemented on the various operating systems. But there is no existing tool that checks the servers, which provide IPsec services, work properly and provide their network security services well. In this paper, we design and implement the rule based security evaluation system for IPsec engine. This system operated on Windows and UNX platform. We developed the system using Java and C language.

This research reviews the concept of Visual Literacy which is the critical base for performing convergence-style educational program of fine arts. The Visual Literacy means the ability to understand and properly deal with the visual information given to the agent such as the literacy to the written language. It is beyond doubt that the necessity of the Visual Literacy is raised because there is different visual information through new media for the entire life of young generation. Therefore, the Visual Literacy is the base for performing convergence-style education when it comes to performing convergence-style educational programs. It covers the communication abilities to utilize new media and exchange visual information one another.

Database Semantics (DBS) attempts to provide a comprehensive and integrated approach to human communication which seeks theory-implementation transparency. Two key components of DBS are Word bank as a data structure and left-Associative Grammar (LAG) as an algorithm. This study aims to provide a pilot implementation of Korean in DBS. First, it is shown how the three separate modules of grammar in DBS, namely, Hear, Think, and Speak, combine to form an integrated system that simulates a cognitive agent by making use of a simple Korean sentence as an example. Second, we provide a detailed analysis of the structure in Korean that is a characteristic of Korean involving numerals, classifiers, and nouns, thereby illustrating how DBS can be applied to Korean. We also discuss an issue raised in the literature concerning a problem that arises when we try to apply the LAG algorithm to the analysis of head-final language like Korean, and then discuss some possible solution to the problem.

Mobile device will be able to use the various contents from the advancement of the wireless Internet and mobile device manufacture technique. Each devices is HTTP headers about under using provides device information to contents provider in the provide the contents. However, There is no standard for device information provided, so interoperability problems, because external contents using mobile phone companies to provide the device information in a different way. International Organization for Standard OMA UAProf about under using it solved interoperability problems from outside. However, in using the UAProf can not provide for the complete device information, because MMS support information, smart card support, information and support for external storage is not specified. Thus, In this paper, we designed UAProf in base which provides the contents which has become optimize to the mobile device of domestic environment the mobile device description language which expresses device information which is necessar, and it used to design and implementation of the Contents Adaptation System.

Semantic role labeling task(SRL) is to extract predicate and arguments such as agent, patient, place, time. In the previously SRL task studies, a pipeline method extracting linguistic features of sentence has been proposed, but in this method, errors of each extraction work in the pipeline affect semantic role labeling performance. Therefore, methods using End-to-End neural network model have recently been proposed. In this paper, we propose a neural network model using the Biaffine Average Attention model for SRL task. The proposed model consists of a structure that can focus on the entire sentence information regardless of the distance between the predicate in the sentence and the arguments, instead of LSTM model that uses the surrounding information for prediction of a specific token proposed in the previous studies. For evaluation, we used F1 scores to compare two models based BERT model that proposed in existing studies using F1 scores, and found that 76.21% performance was higher than comparison models.

Recommendations of ITU-T and ISO stipulate the managerial abstraction of static and dynamic characteristics of network elements, management functions as well as management communication protocol. The current recommendations provide the formal mechanism for the structural parts of managed objects such as managed object class and attributes. But the current description method does not provide the formal mechanism for the behavioral characteristics of managed objects in clear manner but in natural language form, the complete specification of managed objects is not fully described. Also, the behaviour of managed objects is affected by their temporal and active properties. While the temporal properties representing periodic or repetitive internals are to describe managed objects behaviour in rather strict way, it will be more powerful if more dynamic temporal properties determined by external conditions are added to managed objects. In this paper, we added dynamic features to scheduling managed objects, and described, in GDMO, scheduling managed objects that support dynamic features. We also described behaviour of managed objects in newly defined BDL that has dynamic temporal properties. This paper showed that dynamic temporal managed objects provide a systematic and formal method in agent management function model.
