The aim of this study was to subdivide and present the units and the standards of knowledge integration in creating the students' integrated knowledge from content knowledge in college writing classes. For these, it analyzed three typical writing textbooks being used in colleges and examined the ways of presentation on forming integrated knowledge by text qualitative analysis methods. The analysis procedure and the presentation followed Creswell's spiral analysis model It is a method model which repeats the procedure from material collection and analysis to presentation circularly. This examination illustrates three dimensions of the units in forming content knowledge. Also, it suggested those should be all treated for the more systematic education: the units of the whole text, the paragraphs, and the sentences. In the next chapter, the standards and contents of knowledge integration were suggested in each process. For the process of knowledge selection, the suitability and the contradictoriness between the text materials and author's thesis were proposed as the standards and contents. For the process of organization and integration, the corresponsive integration, contradictive integration, background integration, synthetic integration were suggested. Finally the procedure knowledge such as correct expression and spelling, source indication were shown for the process of expression and citation. Furthermore, it showed, in terms of expression, the process of paraphrasing frequently practiced in writing textbooks needs to be exercised in the three dimensions including summarization, connection, and interpretation(or transformation). This result, however, calls for the further study about the subdividing processes to enhance the adequateness to writing textbooks in the level of universities and for a more refined syllabus on the systematic knowledge integration. Accordingly, it suggested the tasks mentioned above for further study.

For semantic retrieval in semantic web environment, it is an important factor to manage and manipulate distributed resources. Ontology is essential for efficient search in distributed resources, but it is almost impossible to construct an unified ontology for all distributed resources in the web. In this paper, we assumed that most information in the web environment exist in the form of RDBMS, and propose a matching method between domain ontology and the existing RDBMS tables for semantic retrieval. Most previous studies about matching between RDBMS tables and domain ontology have extracted a local ontology from RDBMS tables at first, and conducted the matching between the local ontology and domain ontology. However in the processing of extracting a local ontology, some problems such as losing domain information can be occurred since its correlation with domain ontology has not been considered at all. In this paper, we propose a methods to prevent the loss of domain information through the similarity measure between instances of RDBMS tables and instances of ontology. And using the relational information between RDBMS tables and the relational information between classes in domain ontology, more efficient instance-based matching becomes possible.

In the COVID-19 situation, digital textbooks have been used in many schools. In order for digital textbooks to become active even in the post COVID-19 era, the functions of digital textbooks must be improved. Digital textbooks are traditional book-type textbooks with glossaries, video materials, and evaluation questions added. Recently, they are being used usefully for practical education by providing realistic contents such as Augmented Reality, Virtual Reality, and 360 images. Therefore, in this study, in order to prepare for the post COVID-19, we found the functional problems of digital textbooks and suggested a way to improve them. First, the layout of digital textbooks should be developed as a responsive layout, deviating from the same form as a book-type textbook. Second, digital textbooks and learning management systems must be integrated. Third, by developing a digital textbook for teachers, teachers should be able to directly reorganize the contents or add external materials. Fourth, learning analysis should be possible using data recorded in digital textbooks. Fifth, in the 2022 revised curriculum, various subjects should be developed as digital textbooks.

Managing articles on exhibition in the museum these days are generally conducted in manual. With the reason, profound time as well as money is spent without generating proper results and this matter is regarded as a serous problem to be solved. Therefore, in this thesis, a suggestion to solve the consequently difficulty will be provided. In the suggested solution, both portable and fixed RFID readers and an active tag using 900Mhz frequency range are used. In constant, the methods of understanding realtime management of exhibited articles and integrated managing for museum would be developed effectively.

인터넷 접속서비스에 대해서는 사전적 규제를 하지 않는 것이 세계적인 추세였으나, 최근 유럽에서는 인터넷 접속서비스에 대해서 사전적 규제를 가할 수 있는 지침이 채택되었다. EU가 2003년 7월에 채택한 「2003년 프레임워크」는 종래의 수직 통합형 산업구조가 인터넷 기술발전에 따라 물리적인 네트워크, 전송서비스, 콘텐츠로 정보통신산업이 층별로 세분화되어 가고 있다는 사실을 반영한 새로운 규제체계로 평가할 수 있다. 이 규제체계의 방향성은 경쟁이 미진한 분야에는 사전적 규제, 경쟁이 활성화된 분야에는 사후적 규제를 가하는 것이다. 본 고의 목적은 일본의 인터넷 접속서비스에 관한 시장 및 규제 동향을 소개하는 것이다. 여기에서는 먼저 일본의 인터넷 접속서비스 사업자의 현황을 개관한 후, 인터넷 접속서비스에 대한 정부차원에서의 규제동향을 고찰한다. 일본에서는 인터넷 접속서비스에 대하여 사전적 규제를 하지 않고 있다는 점을 감안하여 일본의 대표적 ISP 사업자라 할 수 있는 JPIX와 NTT 동서를 대상으로 인터넷 접속서비스의 사업현황과 이들 기업에 접속하기 위한 접속조건 등을 살펴본다. 맺음말에서는 현재 일본에서 이루어지고 있는 인터넷 접속서비스에 대한 규제동향을 우리나라와의 비교 관점에서 고찰하고 우리나라에의 시사점을 제시하고자 한다.
