이 논문에서는 한국어 형태소 분석기 KMM(Korean Malaga Morphology)을 소개하고자 한다. KMM의 개발 동기는 이후 자연언어 처리 단계의 기반으로 사용될 수 있을 뿐 아니라 이론 형태론 연구의 도구로도 사용될 수 있도록 상세한 형태 동사 의미 정보를 제공하는 것이었다. 이론적 틀은 좌연접 문법(Left-Associative Grammar)에 기초한 LA-MORPH이며, 좌연접 기반 문법 개발 도구인 MALAGA로 구현되었다. LA-MORPH에 기반한 KMM은 분석 실행중이 아닐 때에는 사전의 규모를 최소한으로 유지하다가 분석에 필요할 때에만 분석용 사전을 자동으로 생성한다. 형태소 분석은 분석용 사전에 근거하여, 매칭과 결합이라는 단순한 알고리즘만을 사용한다. KMM의 분석은 동사 어절의 경우, 시제, 서법, 문형, 대우법, 명사 어절의 경우 격정보, 수사 결합어절의 경우 추출된 수랑 정보 등과 같은 상세한 정보를 제시한다. 세종 말뭉치와 KIBS 말뭉치를 KMM 을 이용해서 분석한 결과 각각의 94.96%와 94.59%의 분석률과 88.4%와 90.7%의 정확도를 보였다.

In this day and age physical and cyber boundaries have converged due to the development of new technologies, such as the Internet of Things (IoT) and the Cyber Physical System (CPS). As the relationship between physical system and cyber technology strengthens, more diverse and complex forms of risk emerge. As a result, it is becoming difficult for single organization or government to fully handle this situation alone and cooperation based on information sharing and the strengthening of active defense systems are needed. Shifting to a system in which information suitable for various entities can be shared and automatically responded to is also necessary. Therefore, this study tries to find improvements for the current system of threat information collecting and sharing that can actively and practically maintain cyber defense posture, focusing particularly on the structuring of information sharing platforms. To achieve our objective, we use a risk communication theory from the safety field and propose a new platform by combining an action-oriented security process model.

In this paper, we developed Korean Morphological Analyzer for an automatic indexing that is essential for Information Retrieval. Since it is important to index large-scaled document set efficiently, we concentrated on maximizing the speed of word analysis, modularization and structuralization of the system without new concepts or ideas. In this respect, our system is characterized in terms of software engineering aspect to be used in real world rather than theoretical issues. First, a dictionary of words was structured. Then modules that analyze substantive words and inflected words were introduced. Furthermore numeral analyzer was developed. And we introduced an unknown word analyzer using the patterns of morpheme. This whole system was integrated into K-2000, an information retrieval system.

The World Wide Web is a dynamic collection of pages that includes a huge number of hyperlinks and huge volumes of usage informations. The resulting growth in online information combined with the almost unstructured web data necessitates the development of powerful web data mining tools. Recently, a number of approaches have been developed for dealing with specific aspects of web usage mining for the purpose of automatically discovering user profiles. We analyze sequence data, such as web-logs, protein sequences, and retail transactions. In our approach, we propose the clustering algorithm for sequence data using rough set theory. We present a simple example and experimental results using a splice dataset and synthetic datasets.

The development of computer-based modeling system has allowed the operationalization of cognitive science issues. Human cognition has become one of most interesting research subjects in artificial intelligence to emulate human mentality and behavior. This paper introduces a methodology well-suited for designing the intelligent system of human cognition. The research investigates how to elicit and represent cognitive knowledge obtained from individual city-dwellers through the application of fuzzy relational theory to personal construct theory. Crucial to this research is to implement formally and process interpretatively the psychological cognition of urbanites who interact with their environment in order to offer useful advice on urban problem. What is needed is a techniques to analyze cognitive structures which are embodiments of this perceptive knowledge for human being.

This paper introduces a fundamental investigation into the establishment of a framework for integrating fieldwork into special education teacher preparation programs. This paper introduces a comprehensive framework for the implementation of semester-based practicum systems in special education teacher training programs. The paper delineates essential stages including preparation, adaptation, responsibility readiness, mutual responsibility, and evaluation, emphasizing the importance of collaboration, hands-on training, and feedback interactions. Moreover, the study delves into practical learning frameworks such as the Experiential Learning Model, Sociocultural Theory, and the Apprenticeship of Observation Model. It highlights their significance in connecting theoretical concepts with practical applications and in cultivating reflective practices among pre-service special education teachers. Moreover, the study explores two significant practicum models, namely the Class-Academy Model and the Professional Development Schools (PDS) Model, examining their elements, advantages, and impacts on teacher education programs. The paper provides valuable insights into improving the preparation of special education teachers by incorporating structured practicum experiences and innovative models that blend theoretical knowledge with practical application.

This paper shows the case of the evolution of Korean e-Government services in the theoretical lens of Actor-Network Theory and Structuration Theory. It presents how human actors (i.e. presidents and the central administrations) and non-human actors (i.e. law, standards, and relay systems) have established as the one network together, and how this network affects the evolution of Korean e-Government services. This case demonstrates in public sector can adopt not only Actor-Network Theory, but also Structuration Theory to explain both micro and macro contexts. The practical implications are given especially for the developing countries in pursuing the rapid development process of e-Government services.

This study investigated the differential effects of childhood trauma, especially neglect, emotional abuse, and physical abuse on stress perception in relation to the ToM (theory of mind), among one-hundred and fifty five college students. For this purpose, self-reported childhood neglect, emotional abuse, physical abuse, and stress levels during the previous week were measured. Social cognition was measured using a ToM questionnaire which asked respondents to guess the intentions of the person in each vignette by providing additional hints. In order to examine the predicting role of childhood trauma and mediating role of ToM, two distinct structural models assuming full (Model 1) and partial (Model 2) mediational effects were compared using structural equation modeling. The partial mediational model was supported and the main results were as follows. First, childhood neglect indirectly predicted stress perception through the effect of the ToM. Second, childhood emotional abuse directly predicted stress perception. Third, childhood physical abuse had no distinct effect on stress perception. Finally, the limitations of this study and the implications for future studies are discussed.

Although both ecosystem theory and empowerment have become the most prevalent candidate for integrated paradigm for social welfare practices, they could not overcome completely the long-standing and sharp divides between micro and macro practices, that is, between subject and structure as a main explanatory element in social welfare realm. Along with such traditional dualism and tension, a new emerging divide between modernism and postmodernism regarding intrinsic mission and roles of social welfare has urged strongly to develop the overarching theoretical framework for social welfare practice. In this regard, this study aims to recast the ecosystem theory and empowerment through the reflexive modernization theory of critical sociologist Anthony Giddens. With relatively strong emphasis on human capability coined as the reflexivity, Giddens's own creative theory of modernization can be thoroughly expected to provide a solid foundation of integrated paradigm enough to bridge the existing dualisms in social welfare theory and practice. Especially, his unique account of integrated way of how human agency is involved in the construction of social structure and how to transform each other recursively has profound implication for empowerment to be adequate and proper comprehensive framework for social welfare practice.
