  • In this thesis, a printed score is read by using handy scanner and the recognition process is excuted in parallel, finally, on Mesh-Connected Computer. What is read is classified into certain patterns and is recognized, based on knowledge. The preprocessing steps are minimized and simple operations are used in the algorithm proposed in this thesis. The score symbols on a printed score can be recognized irrespective of their sizes but their diversity males it difficult to recognize them all, so it is programmed so as to recognize some symbols that is used necessarily and frequently. The recognized result is transformed into the MIDI standard file format. It is required to use a parallel processing system with multiprocessors because the high speed image processing is required. A digitized two-dimensional image is appropriate in processing on the SIMD Mesh-Connected Computer(MCC). Therefore, we explain this architecture and present parallel algorithm using SIMD MCC with n processors that achieves time complexity0(n).

  • In order to deeply understand the significance of death aesthetics in contemporary art, this research first summarizes the development process of death aesthetics in art works with popular perspectives, and then classifies and discusses death aesthetics in modern art works. The results of this study are as follows: First, the aesthetic expressions of death are divided into two types: death reproducibility and death symbolism. Death reproducibility includes reproducibility of real objects and reproducibility of imaginary objects. The symbolism of death can be divided into external and internal manifestations. Secondly, in contemporary art, the reproducibility of death through the description of death scenes has increased the various problems and philosophical significance caused by death. Third, in contemporary art, the symbolism meaning of death is not just something directly related to death, it also shows the various psychological states brought about by death. Subsequent research will promote the artists' visual expression of the aesthetics of death in artworks, and the profound changes in meaning that result from it.

  • Nowadays, spatiotemporal data models deal with objects which can be potentially useful for wide range applications in order to describe complex objects with spatial and/or temporal facilities. However, the information needed by each application usually varies, specially in the geographic information which depends on the kind of time oriented views, as defined in the modeling phase of the spatiotemporal geographic data design. To be able to deal with such diverse needs, geographic information systems must offer features that manipulate geometric, space-dependent(i.e, thematic), and spatial relationship positions with multiple time oriented views. This paper addresses problems of the formal definition of relationships among spatiotemporal objects and their properties on geographic information systems. The geographical data are divided in two main classes : geo-objects and geo-fields, which describe discrete and continuous representations of the spatial reality. I study semantics and syntax about the temporal changes of attributes and the relationship roles on geo-objects and non-geo-objects, This result will contribute on the design of object oriented spatiotemporal data model which is distinguishied from the recent geographic information system of the homogeneously anchored spatial objects

  • To reduce the amount of seismic damage, several design codes are being improved considering the earthquake resistant systems, and many researches are being conducted to develop the earthquake damage evaluation techniques. This study develops the Korean seismic fragility function using the modified HAZUS method applicable to PSC-I girder bridges in Korea. The major coefficients are modified considering the difference between the seismic design levels of America and Korea. Seismic fragility function of the PSC-I girder bridge (one of the standard bridge types in Korea) is evaluated using two methods: numerical analysis and modified HAZUS method. The main coefficients are obtained about 70% of the proposed values in HAZUS. It is found that the seismic fragility function obtained using the modified HAZUS method closes to the fragility function obtained by conventional numerical analysis method.

  • Information technology (IT) revolution rapidly advanced from the end of the 20th century has caused an extreme change in the publication market, which brought fierce struggle for existence. In this whirlpool, magazine, which is settling as a part of culture and as a center field of publication, presswork, is concentrating in making new determined position with comparatively liberal theme. So identity study that enables readers to remember a magazine more easily, will suggest a new direction of improvement as a culture business by inducing the brand-making of a magazine. This study is focused on the ability of configuration of its unique image of a magazine building an identity in the magazine design field. Each type of magazine has common characteristics but even though it is grouped into same type, it shows mobility on the relative importance of application according to the strategy of the magazine rather than matching perfectly to the type. The result is limited to the range of professional design magazine. However, through result-pursuing study procedure, it is anticipated of its gui dance of improvement of magazine design at large as well as professional design magazine by inquiring of consequence and utility of Magazine Identity in the digital age and clarifying the role of magazine design.

  • As the number of attacks on vehicles has increased, studies on CAN-based security technologies are actively being carried out. However, since the upper layer protocol of CAN differs for each vehicle manufacturer and model, there is a great difficulty in researches such as developing anomaly detection for CAN or finding vulnerabilities of ECUs. In this paper, we propose a method to infer the detailed structure of the data field of CAN frame by analyzing CAN trace to mitigate this problem. In the existing Internet environment, many researches for reverse engineering proprietary protocols have already been carried out. However, CAN bus has a structure difficult to apply the existing protocol reverse engineering technology as it is. In this paper, we propose new field classification methods with low computation-cost based on the characteristics of data in CAN frame and existing field classification method. The proposed methods are verified through implementation that analyze CAN traces generated by simulations of CAN communication and actual vehicles. They show higher accuracy of field classification with lower computational cost compared to the existing method.

  • Construction industry has a relatively higher accident rate compared to other industries, especially the serious accident rate including death. Ministry of Employment and Labor has not only implemented safety consciousness but also initiated the basic occupational safety and health training for the construction industry. Despite the effort, only a few sites follow the obligatory task and there are reports stating the effect of the education is minimal. As a result, this research aims to determine and analyze the current state of the basic occupational safety and health training including its lesson plan and method. Furthermore, by analyzing the preliminary study on the effective instructional method, this research suggests an effective method to implement safety consciousness to the workers. An improvement plan is also suggested by supplying appropriate educational material to different workers by differentiating the characteristics and the cause of death at various work types in construction sites.

  • Since modern mathematics textbooks were introduced in the late 19th century Korea, arithmetic experts started to teach modern mathematics using Arabic numerals at village schools and churches. After the Gabo Education Reform of 1894, western mathematics education was included in public education and the mathematics textbooks began to be officially published. We explored most of Korean mathematics textbooks from 1895 to 2016 including the changes of mathematics curriculum through 1885-1905, 1905-1910, 1911-1945, 1945-1948, 1948-1953, 1954-1999, and 2000-2016. This study presents the characters of modern mathematics textbooks of Korea since 1885.

  • As defined by the experts, safety education is the basic method through which people can protect themselves from the dangers in workplace. Therefore, safety education is an important safety measure that can be effectively utilized in disaster prevention without any certain limit. The current practice of safety education in construction sites, however, is all formal and has no substance. Safety education became a mere boring time to workers since the material is not related to them, and does not reflect the individual personalities, which cannot induce voluntary participation of workers. Thus, it is vital to develop various safety education models suitable for individual personalities of construction workers. This study aims to provide the basic data necessary to establish safety education models according to individual personalities of construction workers. Based on the analysis of the preliminary stuff and interviews, the typical individual personalities of construction workers and safety education factors were examined, and the frameworks for each were established. Based on results of applying them to actual cases, directions to improve safety education in construction sites are presented.
