As the modern industrial processes become more complex, it is getting more difficult to model and control the processes. Naturally, an advanced type of DCS(Distributed Control System) with higher level functions is being sought. Advanced DCS is a DCS with advanced functions such as fault diagnosis, GPC(Generalized Predictive Control), NN(Neural Network), and Fuzzy Control. In this thesis, we have studied a fuzzy control algorithm for realizing an advanced DCS. Its algorithm is implemented in a form of function code which is a process control language, being used by the industrial engineers. To verify the realized function code of the fuzzy control, the function code is applied to a continuous casting process of the Pohang Iron & Steel Works in Kwangyang. The rules of the fuzzy control were collected via interviews of the field operators and their operation documents. Finally under a real-time operating system environment, usability of the function code of the fuzzy control is shown via simulation for the continuous casting process.

Recently, WRMSD(Work-Related Musculoskeletal Disorders) that can be frequently found among simple and repetitious works has been a big occupational safety issue, and has begun to being studied actively by many Korean researchers. However, those researches have been largely relied on foreign ones, due to the lack of basic data in Korea. In this study, we have tried to search the actual conditions and factors on WRMSD of press workers in a local company. In addition, we examined how the contents of works and postures of the workers affect the disease. It is expected that the data collected in this study will be able to used for planning the preventive measures on WRMSD effectively and for implementing its corresponding programs.

One of the representative side effects in current information and knowledge society is internet addiction. Nowadays single-parent families become popular due to various reasons such as increasing divorce ratio and government supports for single-parent family. National research works showed that internet addiction ratio of single-parent family children is higher than that of children of intact families. The research purpose of this paper is to investigate correlation between internet addiction and parent types. For this purpose, extensive and national survey works of NIA(National Information Society Agency of Korea) are collected and analyzed. Based on statistical analysis work, it is concluded that there is no meaningful correlation between internet addiction and parent types.

In navigation systems that use collected trajectory for routing, the number and diversity of trajectory data are crucial despite the infeasible limitation which is that all routes should be collected in person. This paper suggests an algorithm combining trajectories only by collected GPS data and generating new routes for solving this problem. Using distance between two trajectories, the algorithm estimates road intersection, in which it also predicts the correlated direction of them with geographical coordinates and makes a decision to combine them by the correlated direction. With combined and generated trajectory data, this combination way allows trajectory-based navigation to guide more and better routes. In our study, this solution has been introduced. However, the ways in which correlated direction is decided and post-process works have been revised to use the sequential pattern of triangles' area GPS information between two trajectories makes in road intersection and intersection among sets comprised of GPS points. This, as a result, reduces unnecessary combinations resulting redundant outputs and enhances the accuracy of estimating correlated direction than before.

Animation works have been peformed by the objective sensitivity and experience so far. Software designs have been also manufactured based on intelligent data because they are easy to objectify and digitalize. In contrast, there are many elements, which human senses are hard to objectify and digitalize. This study investigates how to digitalize and objectify human senses and how to use them as the quantitative data and its subject is a flying path. In the experiment, this study collects some sensitive words for how human beings express the living path. The evaluation words for sensitivity through the collected sensitive words are extracted and the sketch images for the flying path are collected from the extracted evaluation words for sensitivity. Based on the collected sketch images, the samples of real moving image, which are the core of this study, are manufactured. Then, quantification theory III and I are used in order to analyze the correlation between the sensitive words representing the flying path and the samples of moving image. As a result, this study can figure out the structure of sensitive words and the samples of moving image and analyze the physical stimulating elements for the flying path. The flying path corresponds to the path that the object has passed. Some unique sensitive words are expressed by means of interacting some sensitive stimulating elements after looking at such a path. There are some elements that stimulate the senses and they include the physical elements such as speed, rotation, pattern and length of arc. The purpose of this study is to objectify and quantify the animation works that are created by animators' subjective thought and experience and to use them in animation works in the future.

This study analysed work types of Chinese bibliographical records based on FRBR model to identify how many useful data there are in bibliographical records and how much difference in usefulness there is according to themes. For the purposes, the study randomly extracted samples of 2,200 Chinese books with 100 cases of 22 kinds from "Chinese Library Classification" through National Library of China's OPAC, targeting Chinese books collected by the National Library of China to analyse the work types of Chinese bibliographical records and their usefulness in application of the FRBR model according to themes and data types. The results are summarized as follows: Firstly, in applying the FRBR model for Chinese bibliographical records, 18.6% was considered as useful works for which simple work was added to complex work. Secondly, although it is a fact that usefulness is higher as bibliographical relations are more complex, only works by famous people collected in 'Marxism-Leninism'(A) and some classics and modern masterpieces collected in 'Literature'(I) have diverse versions of works such as sequels, revision, reproduction, adaptation, and critical books. However, if criticism, review, explanation and bibliographical introduction are included in specific subjects of 'Military'(E), 'Language and Words'(H), 'Literature'(I) and 'Comprehensive Book'(Z), it was clear that their usefulness is relatively high.

In this world of globalism, achieving the winning position in the competitive international market is essential in the area of fashion industry. For this reason, we should accomplish this task by adapting our own traditional beauty to the modern fashion design through the modernization of the Korean traditional style. Therefore, this study attempted to analyze the fashion design works of the active Korean fashion designer, Sul Yoon-Hyung, focusing on the subject how she incorporated the modern fashion design with the traditional motives. In order to study this research subject, both quantitative and qualitative research methods were used to collect and analyse the textile motives used in the designer's works found from the major fashion magazines, Bazaar, Vogue, Marie Claire, ELLE, WWD, and Fashion Today during the last seven years(1993-1999). The collected research data, 68 works, was counted and analyzed in terms of the categories of Korean traditional motives they were adapted from, the application techniques, and the aesthetic characteristics. As a result of the study, it was found that Sul Yoon-Hyung has adapted different kinds of Korean traditional motives including motives borrowed from the nature such as flowers and animals, geometrical forms, and Chinese letters with different specific symbolic meanings for each motif and many different techniques were utilized to apply these motives. It was apparent to note that the Korean traditional motives were successfully incorporated into her fashion design works expressing the beauty of oriental grace, naturalism, sophistication, and above all, the modern sense.
