1. The Purpose of the Research Historical study on the early woodblock printing in Korea has been mostly focussed on woodblock-printed books. Whereas, researches on those who pioneered to develop the advanced culture of the times have been very scant. Meanwhile, extant temple woodblock publications contain well preserved descriptions about Monk-Engravers and Sextons together with respective colophons at the end of the books. These records are very important research materials in the study of woodblock printing history and are also very useful source materials for discernment in conducting historical research about woodblock-printed books. Based on these records, this research has revelaed the characteristics of the Engrevers and realities of engraving activities, and by doing this, has clarified the characteristics of temple woodblock publications, and discussed the historical research about the woodblock-printed-publications by means of the Engravers. 2. Research Methods Temple woodblock publications with colophons in the nation's major libraries have been directly investigated and 3,059 Engravers were identified in 510 different woodblock-printed books, based on which this research and analysis have been conducted. 3. Research Results As a result of the research the followings have been clarified. A The Engravers' status composition and the motivation of engraving. B. The realities and tendencies of the Engravers' activities. C. The characteristics of the times found in the Engravers' lists. D. Historical research methods through the names of the Engravers.

The purpose of thesis is to analyze the radiation characteristics of the parabola reflector antenna. The equivalent sources are used to compute the radiation fields in the far-zone utilizing the aperture integration. Using these results, we obtain the efficiency parameters associated with reflector : aperture efficiency, spillover efficiency, as the function of F/D, diameter beam squint angle and misarrangement.

In this study, we examine the electrical properties of diketopyrrolopyrrole (DPP) containing polymer semiconductors that have been reported to show high performance with ambipolar characteristics. We prepared three different DPP based polymer semiconductors (PDPPTPT, PDPP3T, and PDPP2T-TT) and fabricated organic thin film transistors (OTFTs) with ambipolar polymer semiconductors as an active layer. All three DPP polymers showed only p-type properties at initial measurements. However, after annealing in vacuum oven for 24 hours, it was found that the DPP based polymers have both p-type and n-type properties. It is speculated that the residual impurities supposedly regarded as a strong electron trap source were eliminated during the vacuum process.

An understanding of quality attributes is relevant for the software organization to deliver high software reliability. An empirical assessment of metrics to predict the quality attributes is essential in order to gain insight about the quality of software in the early phases of software development and to ensure corrective actions. In this paper, we predict a model to estimate fault proneness using Object Oriented CK metrics and QMOOD metrics. We apply one statistical method and six machine learning methods to predict the models. The proposed models are validated using dataset collected from Open Source software. The results are analyzed using Area Under the Curve (AUC) obtained from Receiver Operating Characteristics (ROC) analysis. The results show that the model predicted using the random forest and bagging methods outperformed all the other models. Hence, based on these results it is reasonable to claim that quality models have a significant relevance with Object Oriented metrics and that machine learning methods have a comparable performance with statistical methods.

This study aims to implement the electronic record management systems that can preserve and utilize local festival records and archives. To accomplish the goal, this study used open source software for Namwon chunhyang festival as a case. This paper revealed the fact that there is no constructive system for preserving local festival records. To solve this problem, this study implemented electonic records management system based on Open Source Softwares, which are called AtoM(Access to Memory) and OMEKA. Also, both OSSs were compared and evaluated according to Characteristics of Local festival records. As a result, ERMS for Festival based on AtoM was appropriate comparatively.

Organic field-effort transistors (OFETs) are of interest for use in widely area electronic applications. We fabricated a copper phthalocyanine (CuPc) based field-effect transistor with different metal electrode. The CuPc FET device was made a top-contact type and the substrate temperature was room temperature. The source and drain electrodes were used an Au and Al materials. The CuPc thickness was 40nm, and the channel length was $50{\mu}m$, channel width was 3mm. We observed a typical current-voltage (I-V) characteristics in CuPc FET with different electrode materials.

This study aims at establishing a markup system for 17-19th century culinary manuscripts. To achieve this aim, we, in section 2, look into various theoretical considerations regarding encoding large-scale historical corpora. In section 3, we identify and analyze the characteristics of textual theme and structure of our source text. Section 4 proposes a markup scheme based on the XML standard for bibliographical and structural markups for the corpus as well as the grammatical annotations. We show that it is highly desirable to use XML-based markup system since it is extremely powerful and flexible in its expressiveness and scalable. The markup scheme we suggest is a modified and extended version of the TEI-P5 to accommodate the textual and linguistic characteristics of premodern Korean culinary manuscripts.

Fashion is the social process concerned with the spread of a new product from its source to consumer. Fashion leadership may be associated the shopping-related behaviors, such as shopping motives, on-going information search, impulse buying behavior. In order to study the relationship between the fashion leadership and the shopping-related characteristics, Three research problems were set up for the study as follows: Research problem 1: To investigate the fashion leadership. Research problem 2: To analyze the relationship between the fashion leadership and the characteristics of shopping-related behavior. Research problem 3: To analyze the relationship between the fashion leadership and other fashion-related behaviors. After statistical analysis using the SPSSWIN, the following results was found. Fashion leadership approximates the normal distribution curve, and its structure consists of one dimension. Using the factor analysis, the two kinds of shopping motive was confirmed hedonic motive and cognitive motive. Fashion leadership was related to the hedonic shopping motive. Also there were positive associations between the fashion leadership on-going information search behavior, and the impulse buying behavior. And there was significant association between the fashion leadership and expense for clothes and spending time for shopping.

Newspaper Article Information is an important source of information on social phenomenon with historical value. The development of computer and technology of information communication enables the construction of Newspaper Article Database by CTS and service through computer communication. It made it possible for the peoples to utilize the Newspaper Article Information easily. However, it is very difficult to utilize the currently prevailing system. There are differences in classification system of Newspaper Article Database and the Data Display Format. This survey aims to review the characteristics of Newspaper Article Database and current domestic computer communication service system. By comparing the classification system of Retrieval Menu and Data Display Format, I intended to suggest the standardized way of utilization which enables the users utilize them more easily and conveniently. The results of this survey is as follows : 1. More sub-divided distinction of classification item is required. 2. Separate classification item should be established for the distinction of article form which is very difficult to classify the subject. 3. Data Display Format should be equi n.0, pped with standardized format and signal which enables the users recognize it easily.
