본 논문에서는 시맨틱 웹 환경의 핵심기술인 온톨로지 기술을 블로그에 접목하기 위한 블로그 모델링 방식을 제안한다. 블로그에 사용되는 개념과 개념 간의 관계를 온톨로지로 표현하여 공유된 지식으로 이용함으로써 블로그 상에서 보다 세부적이고 정확한 검색 및 추론을 가능하게 하였다. 블로그에 시맨틱 웹 기술인 온톨로지를 적응시킴으로써 사용자의 특성에 맞는 개별화된 블로그 서비스를 제공할 수 있으며 사용자에게 관심 블로그 커뮤니티에 대한 링크 추천이나 사용자 관점에 따른 커뮤니티를 동적으로 구성 할 수 있다. 또한 사용자가 중요하게 생각하는 관점에 따라 원하는 블로그 컨텐츠 검색이 가능하다.

시맨틱 웹의 구현을 가능하게 하는 핵심기술은 도메인 내의 개념들과 개념들 사이의 관계들을 정형적으로 기술한 온톨로지이다. 그러나 온톨로지 생성을 위한 기존 관련연구들의 상당한 부분들은 몇몇의 휴리스틱을 가지는 수작업 형태를 띠고 있다. 기존 연구들의 수작업을 통한 온톨로지 생성은 어려운 작업일 뿐 아니라 시간이 많이 소비되는 문제점을 갖는다. 따라서 본 논문에서는 도메인 온톨로지를 (반)자동으로 생성하는 방법론을 제안한다. 제안한 방법론에서는 데이터마이닝 기법들인 AOI(Attribute-Oriented Induction)와 ID3 알고리즘을 사용한다. 우리는 제안한 접근법이 온톨로지 자동 생성에 있어 실현 가능한 접근법임을 예제로써 증명한다.

The designers pursue the thoughtful and wide thinking through the accumulation of knowledge and cultivation of insights for making use of high-level design philosophy and language. The purpose of this study is to investigate characteristics of concept figuration types based on designer's 'memory' in landscape design. The results of this study are as follows. First, the design idea starts to be based on the language and image memory of the designer. The figuration types are composed of the verbal and visual view which are representative communication means. Second, the verbal concept figuration of landscape design consists of two types. The symbolic language of the title as a design theme can be a 'phrase', and it should have a hierarchial balance between the master and the sub. 'Descriptive shape of conceptual scenario' is a text that expresses the concept narratively in order that the reader virtually experiences designed landscapes. Third, visual concept figuration of landscape design is divided into three types. 'Simple visualization of a diagram' is easily embodied through a simple graphic using symbols, comments, images and key words. 'Concept sketch and shape of core idea' is useful to grasp the core of the idea such as physical element, form attribute of space and spatial relation at the initial phase of the concept. 'A collage and montage that create a new shape with a combination of images' are a collection of materials and images that provide a new perspective. These are tools to depict them in a compressed way after recording landscapes phenomenon.

Gut, Korean shamanist performance, is the archetype of Korean art therapy. It is because gut has the archetype of Korean mind and expresses the archetype in an artistic and therapeutic way. This paper compares and analyzes Gunung-geori of Hwanhaedo-gut and art therapy theories from two perspectives: the range of therapy and the therapeutic principles of performing ways. Gunung-geori aims to solve prolonged conflicts within a family, linking individual problems to family relationship. Such a therapeutic effect of Gunung-geori is well explained through the theory of Bowen's Family Therapy. Also the therapeutic principles that Gunung-geori's performing way are closely related to "transference" of Freud and "putting in the role" in drama therapy.

In this paper, the necessity calling for a paradigm shift in information organization is summarized: an attempt is being made to move from a web of documents to a web of data. In this, the principles used to make a universal library network, as part of the semantic web, or linked data, are described. Popular RDF vocabularies are also briefly introduced emphasizing FRBR and RDA vocabularies. Some library-related linked data projects are also summarized, describing the steps necessary to make a library catalogue available as linked data, as well as a rationale for doing so. Lastly, proposed models for a universal library network focusing on linked data are suggested. Some implications for the use of library applications for linked data, among others, are also presented.

This study suggests new perspective of interorganizational communication. The importance of communication quality is increasing because it affects performance of marketing channels. In perspective of information exchange, communication quality consists of accuracy, availability, timing, and credibility. In research model, the antecedents of communication quality adopt willingness of information sharing and capability of efficient communication. To examine effects of communication quality on channel performance, research model includes relation of communication quality and conflicts. For empirical test, relation of PC makers and their dealers is decided as a focal dyad. Findings indicate that overall hypotheses are supported except the relation of willingness of information sharing and communication quality.

This study aimed finding effective models for the teaching the concept of function. We selected two models. One is discrete model which focuses on the 'corresponding relation of the elements of the sets(domain and range). The other is continuous model which focuses on the dependent relationship of the two variables connected in variable phenomenon. A vending machine model was used as a discrete model, and a water bucket model was used as a continuous model in our study. We taught 2 times about the concept of function using two models to the 60 students (7th grade, 2 classes) living in Taebak city, and tested it twice, after class and about 3 months later. A vending machine model was helpful in understanding the definition of function in the 7th grade math textbook. Also, it was helpful to making concept image and to recalling it. On the other hand, students who used the water bucket model had a difficultly in understanding the all independent variables of the domain corresponding to the dependent variables. But they excelled in tasks making formula expression and understanding changing situations.

This study identified terminologies related to the proximity and frequency of disaster by social network analysis (SNA) and text mining, and then expressed the outcome into a mind map. The termdocument matrix of text mining was utilized for the terminology proximity analysis, and the SNA closeness centrality was calculated to organically express the relationship of the terminologies through a mind map. By analyzing terminology proximity and selecting disaster response-related terminologies, this study identified the closest field among all the disaster response fields to disaster response and the core terms in each disaster response field. This disaster response terminology analysis could be utilized in future core term-based terminology standardization, disaster-related knowledge accumulation and research, and application of various response scenario compositions, among others.

Causal questions are prevalent in scientific research, for example, how effective a treatment was for preventing an infectious disease, how much a policy increased utility, or which advertisement would give the highest click rate for a given customer. Causal inference theory in statistics interprets those questions as inferring the effect of a given intervention (treatment or policy) in the data generating process. Causal inference has been used in medicine, public health, and economics; in addition, it has received recent attention as a tool for data-driven decision making processes. Many recent datasets are observational, rather than experimental, which makes the causal inference theory more complex. This review introduces key concepts and recent trends of statistical causal inference in observational studies. We first introduce the Neyman-Rubin's potential outcome framework to formularize from causal questions to average treatment effects as well as discuss popular methods to estimate treatment effects such as propensity score approaches and regression approaches. For recent trends, we briefly discuss (1) conditional (heterogeneous) treatment effects and machine learning-based approaches, (2) curse of dimensionality on the estimation of treatment effect and its remedies, and (3) Pearl's structural causal model to deal with more complex causal relationships and its connection to the Neyman-Rubin's potential outcome model.
