본 연구에서는 클라우드 환경에서 기하급수적으로 증가하는 전사적 정보 연계를 위한 시맨틱 기반 개념 망을 이용하여 전사적 데이터들의 효율적 연계와 활용이 가능하도록 프레임워크를 제안한다. 개념 망은 기존 온톨로지에 접근하는 방식은 유사하지만, 사용자가 보다 효율적으로 정보 연계 검색을 하고자 객체와 개념 사이의 연관성을 구축 한다. 본 논문에서는 개념 망을 3가지로 구분하여 제안 프레임워크에 적용한다. 본 연구의 개념 망은 마스터 정보 개념 망, 키워드 개념 망, 그리고 비즈니스 프로세스 개념 망을 기반으로 온톨로지 형태로 구축된다. 이 개념 망은 사용자 요구사항에 따라 데이터들 간의 연관성을 기준으로 하여 검색 및 활용을 가능하게 한다. 그리고 마스터 정보 개념과 키워드 개념이 결합되어 검색 키워드의 빈도 및 카테고리의 빈도 추적을 제공함으로써, 사용자의 검색의 편의성과 신속성을 향상시킬 수 있도록 하였다.

It is not easy to find desired information in the world wide web. In this research, we introduce a notion of concept network that is useful in finding information if it is used in search engines that are specialized in domains such as medicine, law or engineering. The concept network that we propose is a network in which nodes represent significant concepts in the domain, and links represent relationships between the concepts. We may use the concept network constructor as a preprocessor to speci-alized search engines. When user enters a target word to find information, our system generates and displays a concept network in which nodes are con-cepts that are closely related with the target word. By reviewing the network, user may confirm that the target word is properly selected for his intention, otherwise he may replace the target word with better ones discovered in the network. In this research, we propose a detailed method to construct concept net-work, implemented a prototypical system that constructs concept networks, and illustrate its usefulness by demonstrating a practical case.

This study analyzed an operational concept for the D Information Resource Management Information System (DIRMIS) to manage any IT resources effectively in defense area. We first deduced the concept of the information resource management (IRM) for defense area from the literature review, and we suggested a guideline, which has used in defense area, of the documentation for the operational concept description (OCD). Moreover, we developed the operational concept for the DIRMIS following the guideline. Especially, this study is a practical approach for suggesting of a case, and the share of accumulated cases will contribute to advance in System Integration (SI) industry as well as academic research.

The writer has made efforts to solve the weaknesses of the traditional systems through reconstructing cost information systems by introducing 'logical circuit concept' instead of account. As the new designed systems also allow the basic thought of double entry, they are compatiable with the traditional ones. For this, the writer included both monetary and physical information in the systems, replaced the concept of debit & credit with the concept of inputs & outputs, and changed transfer concept between accounts based on reverse logic into flow concept between unit systems based on proceeding logic.

본 논문은 모바일 클라우드에서 급격하게 증가하는 정보 검색을 위한 키워드 기반의 개념 망을 이용한 데이터를 효율적으로 검색 가능하도록 한 모델을 제안한다. 키워드 기반의 개념 망은 온톨로지를 적용한 방식이지만, 사용자가 효율적인 정보 검색을 하도록 지원하기 위해 개념 사이의 연관성을 추가한 것이다. 따라서 본 논문에서는 키워드 중심의 개념 망, 전문가 그룹이 추천한 분야 개념 망 그리고 프로세스 개념 망으로 구성한다. 이러한 3가지 종류의 개념을 이용하여 사용자는 모바일 클라우드 내에서 키워드 기반으로 정보를 검색하고, 검색된 결과에 따라 연관성 있는 정보를 검색할 수 있다.

Objectives: This study was conducted to investigate the effect of professional self-concept and ethical awareness of dental hygiene (department) students attending a university located in Gwangju and Jeollanam-do on patients' willingness to protect personal information. Methods: Professional self-concept, ethical disposition, and patients' personal information protection intention according to general characteristics were analyzed using t-tests and one-way ANOVA. After confirming the correlation through Pearson's correlation analysis, the effect on the patient's personal information protection intention was confirmed using multiple regression analysis. Results: Professional self-concept, ethical disposition, and the patients' willingness to protect personal information all showed positive correlations. The higher the communication skills of professional self-concept and the higher the idealism of ethical orientation, the higher the patients' willingness to protect personal information. Conclusions: This study, ascertained the effect of dental hygiene students' professional self-concept and ethical consciousness on patients' personal information protection practices. The results suggest that it is necessary to develop an educational program that can enhance the practice of dental hygienists to protect patients' personal information, and to develop and conduct continuous policy development and research.

본 논문에서는 개념망을 이용한 효율적인 정보검색을 위한 방법을 제안한다. 본 논문은 일반적인 개념망을 기반으로 시스템을 설계하였기 때문에 온톨로지와 접근 방식은 같지만 사용자가 보다 효율적으로 정보검색을 하고자 하는 객체와 개념사이의 협업 관계를 구축하여 사용할 수 있도록 개념망을 제안한다. 제안한 시스템은 다음과 같다. 첫 번째, 입력 키워드 중심의 키워드 개념망과 전문가 그룹이 추천한 전문가 개념망 그리고 테마 개념망 이러한 세 종류의 개념을 이용하여 협업적 검색을 하며, 이를 기반으로 사용자가 원하는 정보를 검색할 수 있는 효율적인 검색 시스템을 제안한다. 그리고 전문가 개념과 키워드 개념이 결합되어 키워드의 빈도 및 카테고리의 빈도를 제공함으로써, 사용자가 입력한 검색어와 관련된 키워드를 추천하는 역할을 할 수 있다. 그리고 테마 개념망을 이용하여 사용자의 관심 테마에서 사용되는 키워드 또는 카테고리를 알려주는 기능도 제공한다. 두 번째, 사용자가 입력한 키워드가 없을 경우 2차 검색을 통해 입력 키워드와 관련 있는 키워드를 제공해줌으로써 관련키워드를 이용하여 검색의 목적달성이 가능하다. 세 번째, 이러한 정보들은 대부분 분산되어 관리되고 있기 때문에 이렇게 분산되어 관리되는 정보는 표현방식이 다를 뿐만 아니라 시간에 따라 정보가 변하게 된다. 따라서 분산된 정보의 효율적 데이터 접근 및 통합을 위해 XMDR(eXtended Mata-Data Registry)을 이용하였고, 본 논문에서는 분산된 데이터를 통합하기 위한 기법 및 검색 시스템을 제시한다.

Information culture is a concept with multiple and sometimes conflicting definitions. Nevertheless at a time when social and cognitive aspects of information and communication systems are recognized as being of similar significance as the technological functionality, the concept of information culture is demonstrating considerable value. This paper explains the concept of information culture and considers its value from two main perspectives: firstly as providing an analytical tool, and secondly as a means of providing practitioners with insight and sensitivity to the organisational contexts of their workplaces.

Purpose: To define the concept of digital health literacy and identify its attributes. Methods: Walker and Avant's approach was employed for concept analysis. Attributes, antecedents, consequences, and the definition of digital health literacy were derived from a review of 28 studies. Results: Digital health literacy was identified to possess the following five attributes: health information seeking, health information processing, health information communication, health-related knowledge translation, and utilizing digital technology. Basic literacy skills, health concerns, motivation to use technology for health information, and access to digital technologies were all antecedents of the concept. The consequences of the concept were health behaviors, patient engagement, health status, and quality of life. Digital health literacy is the ability to seek relevant health information utilizing digital technology to solve health problems and improve quality of life. Furthermore, it refers to the translation of health-related knowledge obtained through health information processing-finding, understanding, and evaluating health information and health information communication-into the context in which individual and social factors interact. Conclusion: This study presented a new definition of digital health literacy that goes beyond existing internet-based eHealth literacy, by incorporating the context of emerging digital technologies. This proposed definition can serve as a foundation for the development of instruments and educational programs to improve individuals' digital health literacy.

In this paper, we constructed a two-phase spam-mail filtering system based on the lexical and conceptual information. There are two kinds of information that can distinguish the spam mail from the ham (non-spam) mail. The definite information is the mail sender's information, URL, a certain spam keyword list, and the less definite information is the word list and concept codes extracted from the mail body. We first classified the spam mail by using the definite information, and then used the less definite information. We used the lexical information and concept codes contained in the email body for SVM learning in the 2nd phase. According to our results the ham misclassification rate was reduced if more lexical information was used as features, and the spam misclassification rate was reduced when the concept codes were included in features as well.
