A comparative study on analytico-synthetic systems and enumerative systems which have been used in Korea was dealt. The writer tries to compare the adaptability of both systems for Korean author notations. The following topics are discussed in detail: 1) The objectives of the book numbers. 2) Korean alphabet as author numbers. a) Brevity, simplicity and the possibility of expansion. b) A study on the defects of the analytico-synthetic notation devised by Professor Jai Chul Lee. c) A study on the pronounceability and the ambiguity. 3) A comparative study on filing efficiency of the Professor Lee's author marks and the writer's.

In this investigation the PFM(Pulse Frequency Modulation} will be used for optimizing PWM inverter pulse pattern. In traditional the pulse frequency of PWM is kept const. But modulated PWM's frequency in this study, the sinusoidal inverter's performance should be improved. The PWM pulsepatterns are definitely controlled so that the time-integral function of the voltage vectors in the space vector notation may show a circular locus. Further, performance index will be minimized because of minimizing distortion of output current. Finally, we will implement itusingsingle-chip microprocessor.

In this paper, SA-multiplexed filter is designed using SA (simulated ananealing) to recognize music notation patterns varying in size, shape, position and having considerably many similar shapes for optical pattern recognition system. This filter has correlation resutls at wanted location and can identify same class, classify similar class for scale-varianted or rotation-varianted music notation patterns havng learning process. Also, the optimum filter is oriented to analyze on the similar discrimination at acquired position using SA and enhances optical diffractive efficiency as well as peak beam intensity. Compared with POF *(phase only filter), cosine-BPOF(cosine-binary phase only filter), that has excellent discrimination capability even if the different rate is 0.1% quantitatively.

Human exists in environment. As environment affects in human movement, human reacts to everything happens in environment especially by the view point of visual continuity and changeability. This study has two purposes. The one is to clarify the visual changeability due to the Human movement from the visual point based on checking the visual field. And the other is to understand the applicable possibility of Philip Thiel's method through the experiment in passing ways. Condition of this study is that colors and figures are affective elements of visual environmental sequence by the Human movement. The Human movement is due to the visual phenomenon. That means it is not limited in Philip Theil's method(Node, District). In particular, the chroma which is checked by the BPA(Basic-Pattern-Area) is the most affective visual environmental element in contemporary shopping mall. Also, everything in visual environment and the movement is connected by the time axis. As an analytical method, the sequence notation devised by Philip Thiel was applied.

PC용 작곡 프로그램의 보편화에도 일반인들이 음악제작을 어려워하는 이유는 악기를 다룬 경험의 부족, 음악 또는 작곡의 지식부족, MIDI 소프트웨어 학습에 대한 두려움 등이다. 본 논문에서는 이러한 문제를 해결하기 위한 기술로 MIDI를 전혀 모르고, 악기를 다룬 경험이 부족하고 또한 악보조차 읽지 못하더라도 음악의 제작 및 작곡, 편곡이 가능한 효과적인 일반 텍스트 기반 음악 표기법을 제안한다. 이를 통해 음악을 좋아하지만 자신의 음악을 제작하지 못했던 많은 일반인들에게 음악을 제작, 보급하는데 큰 도움이 될 뿐 아니라 타인과의 협업을 통해 우수한 품질의 음악을 제작할 수 있다.

Most of the previous game development has proceeded in the approaches of the temporal-oriented synchronization because of producing game objects by using general authoring tools, and ad hoc or trial and error methods has been devised for representation of spatial concept. This paper is a study on the unification notation for spatio-temporal synchronization to conquest this fault. First of all, we classify game space as temporal object, spatial object, absolute/relative spatio-temporal space. The spatio-temporal relationships are divided into temporal extent, temporal location, spatial extent, and spatial location. In the paper the temporal and spatial relationships of game scene are defined to represent the synchronization, and we propose new unification notation by temporal and spatial concept to represent two concepts putting emphasis on space. Their relationships are presented on 3D by creating time axis related with time in scene unit of the two dimensional plane in the pivot on space. The usability of this representation method are shown by applying examples of game scenario.

With the development of computer music notation programs, when drawing sheet music, it is often drawn using a computer. However, there are still many use of hand-written notations for educational purposes or to quickly draw sheet music such as listening and dictating. In previous studies, OMR focused on recognizing the printed music sheet made by music notation program. the result of handwritten OMR with camera is poor because different people have different writing methods, and lens distortion. In this study, as a pre-processing process for recognizing handwritten music sheet, we propose a method for recognizing a staff using linear regression and a method for recognizing a bar using CNN. F₁ scores of staff recognition and barline detection are 99.09% and 95.48%, respectively. This methodologies are expected to contribute to improving the accuracy of handwriting.

In this study, we surveyed the current status and sizing system of the custom dress shirts sold through online shopping, compared with the sizing system of the ready-made dress shirts. We tried to collect the information needed to make the well fitted dress shirts for middle-aged men from this study. The 17 online custom dress shirt brands were selected and the sales type, sales price, design options and size options of each brand were analyzed. The sizing systems of online custom dress shirt brands were compared with the sizing system of the 10 ready made dress shirt brands. The result showed that online custom dress shirts brands offered a variety of design options and size options to meet the consumers' individuality, taste and demand for good fit. In the ready-made brands, all 10 brands were using the same size notation system. In the same size designation, the difference in product size among the ready-made brands showed a tendency to be smaller than the online custom brands. The online custom brands had the different size notation system among brands. The size notation, the number of size designation and the size interval were different for each brand. Also, in the online custom brands, the product size among brands differed from each other in the same size designation. Therefore, the standardized size information and sizing system for middle-aged men that could be used as criteria when making the product size and pattern design in online custom brands were needed.
