The objective of this study is to design an automatic abstracting system through the analysis of natural language texts. For this purpose a knowledge-based system operating on the basis of domain knowledge was developed. The procedure of generating an abstract consists of three steps: (1) A knowledge-base containing domain knowledge necessary to understand a text is constructed using frame and semantic network structures,and preliminary abstracts are prepared for various cases. (2) Input text is analysed on the basis of domain knowledge in order to extract information filling slots of the abstract with. (3) A Preliminary abstract corresponding to the input text is called and filled with the information, completing the abstract.

Records related to a certain cultural heritage are concrete evidence that prove the value of the cultural heritage and become a criterion for long-term preservation of its records. The value of the records is as important as cultural heritage value. In the case of specific cultural heritage with national or socially important values, various studies are conducted on cultural heritage as one theme, and various programs about cultural heritage are developed. However, it is difficult to grasp the scope, record types, and contents of the records because they have been distributed and managed in many institutes. They also appear in various forms. As a solution to these problems, this study collected records of a major cultural heritage with social and historical values such as Hwangnyongsa from 11 public institutions and web services and analyzed the types of records, activities related to the records, and metadata. Through data analysis, an ontology that can understand the range and relationship of the entire record was suggested so that the record can be understood with a focus on specific cultural heritage.

본 연구의 주제는 텍스트를 어떻게 회화적이미지로 전환시킬 수 있을까?에 대한 것이다. 오늘날 디지털 환경 속에 있는 우리는 이미지 중심의 세계 속에 살고 있다. 과거 텍스트가 해왔던 정보의 생산과 전달 그리고 저장의 역할을 오늘날은 상당부분 이미지가 하게 되었다. 하지만 그럼에도 불구하고 아날로그 방식과 정서는 여전히 우리 곁에 남아있는 것도 사실이다. "Yesterday to Today"는 문자의 최소 단위인 알파벳을 통하여 이미지를 재현하려는 작품이다. 이 작품은 크게 두 가지 Idea로 이루어지는데 하나는 복수개의 실시간 영상 소스를 이용하여 이미지를 구성해내는 것과, 다른 하나는 텍스트에 의한 이미지의 변환이다. 복수개의 실시간 영상 소스는 프로그램이 작동하는 컴퓨터와 직/간접적으로 연결되어 전달되는데, 직접적으로 연결되어 근거리의 특정한 지점으로부터 영상 소스를 받을 수 있고, 또 하나의 방법은 인터넷을 통한하나 이상의 원거리 지점으로부터 보내어지는 영상을 조합하여 받을 수 있다. 프로그램 구현 개념은 픽셀 소스 카메라에서 캡쳐된 최초 이미지를 명도, 색상, 채도로 분류하고, 이것의 각각을 26개의 구간-자판의 개수에 의하여 정해짐-으로 나누고, 다시 그 각각의 구간을 26단계로 나눈다. 이렇게 나누어진 구간들은 알파벳과 1:1로 대응시켜 결과이미지의 해당 부분을 수치대로 재현하도록 프로그램 시킨다. 이미지의 부분들을 지정하기 위하여 특정한 텍스트로부터 알파벳의 빈도수를 조사했는데, 이 조사를 바탕으로 빈도수의 많고 적음에 따라 이미지부분들이 26개 구간으로 정해졌다. 이미지 재현 방법은 사용자가 모니터 위의 Result Image Cam을 통하여 얻고자 하는 이미지를 캡쳐한 후, 특정한 텍스트를 타이핑하면 이미지를 재현할 수 있는데, -입력된 텍스트의 알파벳은 프로그램이 지정한 HSI 컬러 모델의 영역과 1:1로 대응하게 하였다-이 이미지는 특정 장소에 실시간으로 받아진 영상을 데이터화 한 소스에 의하여 만들어진다. 이미지를 재현할 때 텍스트에 따라 알파벳 빈도수는 달라질 수 있으므로 비록 최초 이미지가 동일할지라도 얻고자하는 결과 이미지가 달라진다. 그러므로 사용자는다양한 창조적 경험을 할 수 있다.

This Study is an analysis of the tourism geography for Past thirty years and an indicator for the future. I searched for the specificity by classifying of subjects, periods, and Researcher's achievements and tendencies. The Results are followings: (1) Sightseeing places are superior to visitors in research activities. Research activities are outstanding in developing sightseeing site and Its effect as well as geographical research about city and hot spring. The research activity to tourist was occupied a great number tourist behaviour to tourism place but the research was insufficied somewhat inhabitants in tourism place. (2) According to the period and results analysis. The period of domestic study is divided in to 3 steps. 1970s are said to be the pre-step for developing, 1980s are said to be growth step, but 1990s are considered as the age of maturity in the multiful research realm and broad theme. Finally, I think it is difficult to analyse total outcome to the tourism geography by limited data. This study will be evidencied on the objective standard by multiful data in nearly future because this indwelled in the subjectivity on the subject choice and process of the object classification.

The purpose of this study is to develop theme-based integrated science unit by the interdisciplinary approach and to analyze it's effects on the science achievement and the attitude towards science learning. 'Interaction' and 'Stability' were selected as the integrated themes, and the main concept and subconcept in relation to the themes were extracted from the four areas of science, and the learning contents were constructed in the integrated ways. While the main concept have relevance to subconcept in the interaction, the main concept have little relevance to subconcept in the stability. Therefore, the stability was to fit with middle school integrated science theme, but the interaction was not. The theme-based integrated science units developed was implemented in middle school, and the results are follows. First, the science achievement of group of theme-based integrated science teaching is significantly higher than those of group of traditional teaching. Second, the scores of the test of attitude toward science learning of the group of theme-based integrated science teaching is significantly higher than those of group of traditional teaching. Third, the students' perception of theme-based integrated science teaching was positive. The students have participation, interest, motivation in theme-based integrated science teaching, and students have difficulty in learning theme-based integrated science teaching.

This study comparatively analyzed the instrumentation and the voicing structure, which were shown in the film music titled "Star Wars-Main Title" by John Williams(1932~), with analytical technique that the writer mapped out, and aimed to discover the progression principle in orchestration based on the results. Also, it applied a functional part-division method that was classified and distributed into 3 functional parts according to auditory cognitive level as for each of functional elements such as the musical element. And, it made it pattern for the vertical structure and the voicing structure in musical instruments, which were distributed to each functional part based on this, and comparatively analyzed the standard point in a change which were shown according to progression of music, namely, the operating technique. As for the results of this study, first, each theme has specific instrumentation pattern. Unity was emphasized by consistently organizing those things in exposition, reprise, and recapitulation of each theme. To reinforce diversity, an attempt was made such as adding and reducing auxiliary instruments in the middle part and the rear part. Second, even in a change of instrumentation pattern by passage in accordance with a change in theme amid each part, the same instrumental group was organized in the middle part, thereby having maintained unity. Third, to strengthen diversity by clause, which is forming each theme, a continuous change in voicing pattern was created by adding or omitting a part. Fourth, the voicing concentration was maintained the structure of "thinness-thickness" in the whole musical piece. However, in part 2 that is repeated theme 3, diversity was pursued with a unique change of "thickness-thickness." Fifth, in part 4 that is indicated theme 4, the other diversity was intensified with the inverted range in the front part and the middle part. Accordingly, based on the conclusions that were indicated in this work, it is desired to be conducive to understanding the horizontal consideration and the progression principle of orchestration.

This paper's purpose is to get hold of the recent research trend by analyzing the variables uesd in startups related papers. The startups related papers in this paper are the papers which include 'startups' in the title of the registered papers from the year 2013 to the year 2020. This study's analysis methods are text-mining of all variables and text-network analysis of affected variables. Visualizing tool for network analysis is Gephi. The result of variables' analysis is as follows. First, independent variables consist mainly of variables about startups' internal factors and outside environment, but due to startups' features like early stage company's features, innovative features, most of variables are about enterprise internal competitiveness, marketing 4P strategy, entrepreneurship, coopreation method, transformational leadership, enterprise features, lean startup strategy, enterprise internal communication, value orientation, task conflict, relationship conflict, knowledge sharing, etc. Second, dependent variables are mainly about outcome, and are classified into financial performance and non-financial performance by overall concept. In other words, startups related papers have higher interest in non-financial performance, like management performance, team performance, SCM performance as well as financial performance like sales quantity owing to startups' immaturity in getting good financial performance. Through this study we can find out as follows. Although there are not many officially registered papers dealing with startups, those papers include various themes about stratups. For example, there are trendy themes like lean startups strategy, crowdfunding, influencer and accelerator, etc.
