The purpose of this study is Korean fashion designers' tendency and degree to adopt and receive overseas fashion trends, as a founding work to suggest a direction for Korean fashion industry and designers to select and adopt overseas fashion trends. 204 survey results out of 270 ones from the same number of fashion designers in 68 brands, who work in domestic mass-fashion female-garment brands for more than 3 years, are used as final analysis data. For the data analysis, SPSS, ${\chi}^2$-verification, variable analysis and MANOVA are executed, and statistical significance is verified at significance level 0.05. Conclusions obtained from the result and discussions of study are as follows: 1) The periods for domestic fashion industry to need to adopt overseas fashion trends are during 1992-94, and 1986-88. 2) There are discrepancies of utilization of design factors per brand concept. 3) When a line which is not suitable to domestic consumers is presented as subject of fashion trend, there are difficulties to reflect, and per brand concept there are differences of reflection sequence. 4) Whether or not to develop independent themes is dichotomized per brand concept.

순차적인 관찰값을 바탕으로 하고 신호검출에 소요되는 시간이 고정된 신호검출기의 제작에 관한 방법을 제안하며 이는 하드웨어의 복잡도를 감소시키는 장점이 있다. 제안된 방법은 Voronoi 다이어그램과 Delaunay 분할을 사용한다. 제안된 신호검출기 제작은 또한 고정 지연 트리 검색 검출 (FDTS) 방법에 기반을 둔다. FDTS 는 효율적인 순차적 신호검출 알고리즘이며 심볼간 간섭이 존재하는 채널에서 결정 궤환 등화기법 (DFE)과 결합하여 최적화에 근접한 성능을 보인다. 이러한 접근방법에서는 Voronoi 다이어그램 혹은 등가적으로 Delaunay 분할에 포함된 정보를 활용하여 다차원 유클리드 공간에서의 상대적인 관찰값의 위치를 계산하며 이러한 방법이 효율적인 계산을 유도하는 신호검출기의 제작에 이용된다.

In this paper an effort is made to develop an innovative spatial arrangement concept pertaining to ship building industry. The spatial scheduling is the problem that concentrates on effective planning of available space and arrangements of blocks and in a priority manner. In order to create an effective spatial scheduling. a database providing the priority has to be available to make the erection sequence. Such a system works hand in hand with erection sequence generator program The erection sequence program works on the conventional network analysis method which uses a typical parent-children idea for the calculation of the ENT(possible earliest network start time) and LNT(possible latest network start time). This program works in a cyclic manner taking turns by calculating the ENT in upward trace and LNT on the return trace thereby generating the entire erection sequence diagram for the requisite problem The generated database serves as an input data for spatial scheduling problem. When the system works it takes into consideration the entire system based on heuristic concepts as mentioned. There system uses the spatial aspects such as the available area of the P. E area and plan area of the corresponding blocks and its priority of erection from the erection sequence generator program develops the spatial scheduling arrangement. In this paper using all these concepts an innovative spatial schedule development system developed.

시공단계에 따른 철근콘크리트 구조물의 장기변형 해석은 설계 및 시공에 있어서 매우 중요한 요소이다. 하지만 기존의 많은 해석적 연구들은 그 적용기법의 단순화로 인하여 실제 구조설계 및 시공에 대부분 반영되지 못하고 있다. 동바리와 기둥에서는 축력 재분배가 시간에 따라 계속적으로 변화되기 때문에 콘크리트 타설, 거푸집 제거, 동바리 재설치, 동바리 제거 및 이에 따른 추가하중의 작용과 같은 전반적인 시공단계를 그대로 적용하여 해석하는 것은 매우 중요한 요소이다. 따라서 본 논문에서는 이와 같은 시간에 따른 시공단계별 해석을 객체지향 알고리즘으로 개발하였다. 본 시스템에서는 입력모듈, DB 모듈, DB저장 모듈, 해석모듈 및 결과분석모듈로 구분하였으며, 각 모듈간의 연계는 visual c# 루틴으로 처리하였다. 또한 그래픽 인터페이스와 DB 테이블은 사용자 편의성을 고려하여 개발하였다.

본 논문에서는 동역학계를 해석하는 방법들 중의 한가지인 다차원 셀룰라 오토마타에 기초한 난수열 발생 시스템을 제안하였다. 제안된 난수열 발생 시스템은 키의 사용이 요구되는 경우와 요구되지 않는 경우에 모두 적용이 가능하도록 구성되었으며, 키를 사용하는 경우 키의 크기는 128bits에서 256bits까지 가변적으로 사용할 수 있게 구성되었다. 제안된 난수열 발생 시스템의 수행속도는 Pentium MMX 200MHz (64M RAM, Windows 98) 환경에서 약 280Mbits/sec로 측정되었다.

This study is concerned with the scheduling problem for mixed-model assembly lines in Just-In-Time(JIT) production systems. The most important goal of the scheduling for the mixed-model assembly line in JIT production systems is to keep a constant rate of usage for every part used by the systems. In this study, we develop two heuristic algorithms able to keep a constant rate of usage for every part used by the systems in the single-level and the multi-level. In the single-level, the new algorithm generates sequence schedule by backward tracking and prevents the destruction of sequence schedule which is the weakest point of Miltenburg's algorithms. The new algorithm gives better results in total variations than the Miltenburg's algorithms. In the multi-level, the new algorithm extends the concept of the single-level algorithm and shows more efficient results in total variations than Miltenburg and Sinnamon's algorithms.

Narratologists have long raised the question of how narrative theories could be applied to other disciplines that involve stories and storytelling. Focusing on recently revitalized concepts of space, sequence, and story, this article attempts to illustrate narrative constructions in various fields of arts and humanities and examine them particularly in typographical works. Through the concept of narrativity, this article highlights the prevalent uses of narrative in typography and scrutinizes the ways in which a sense of storyness is forming and emerging in some typographical works. Particularly emphasized are the importance of and interplay between the formal and cultural attributes of narrative that transform the spatial world of visual images to the temporal world of stories. Narrative is arguably the most familiar, interesting, and effective medium of communication regardless of age, race, and culture, and can be critically rethought to apply to typography and design.

In this report, as the active position measurement system, a new method for two-dimensional position measurement system using a concept of semi-open type signal field has proposed. The feature of this system is realizing a position measurement only by scanning the encoded laser beams from scanning points to a measurement field, and observed it. First, both system configuration and encoding method are considered concretely, and M-sequence signal is selected for encoding. Next system design is performed to realize the theoretical measurement accuracy, and applied to a position measurement experiments. Experimental results show that measurement precision is larger than theoretical values. Furthermore, method for improving the measurement ...

"Motion Stereo" is quite useful for visual guidance of the robot, but most range finding algorithms of motion stereo have suffered from poor accuracy due to the quantization noise and measurement error. In this paper, 3-D position estimation and refinement scheme is proposed, and its performance is discussed. The main concept of the approach is to consider the entire frame sequence at the same time rather than to consider the sequence as a pair of images. The experiments using real images have been performed under following conditions : hand-held camera, static object. The result demonstrate that the proposed nonlinear least-square estimation scheme provides reliable and fairly accurate 3-D position information for vision-based position control of robot. of robot.

A musical key is a fundamental concept in Western music theory. It is a collective characterization of pitches and chords that together create a musical perception of the entire piece. It is based on a group of pitches in a scale with which a music is constructed. Each key specifies the set of seven primary chromatic notes that are used out of the twelve possible notes. This paper presents a method that identifies the key of a song using Hidden Markov Models given a sequence of chroma features. Given an input song, a sequence of chroma features are computed. It is then classified into one of the 24 keys using a discrete Hidden Markov Models. The proposed method can help musicians and disc-jockeys in mixing a segment of tracks to create a medley. When tested on 120 songs, the success rate of the music key identification reached around 87.5%.
