종교상징에서 '문장(紋章, emblem)'은 '상징적 표지(標識, symbol mark)'로서 다른 대상이나 종교를 구별하게 한다. 또한 특정 종교를 확정하고 인식할 수 있게 하는 표상적(表象的) 혹은 개념적 특성을 가지게 한다. 한국의 대표적 민족 종단인 대순진리회 역시 상징이 되는 문장이 존재한다. 하지만 이 상징에 대한 공식 명칭은 없으며, 이 문장의 도안이 도기(道旗)로 제작되어 알려져 있다. 이 문장의 도안은 1978년 5월 11일 제작되었고, 이후 같은 해 10월 20일에 공식 게양되어 지금에 이르고 있다. 도기에 있는 대순진리회의 문장은 종단의 상징적 표지로서 종단과 관련한 여러 디자인에 활용되고 있지만, 이에 관한 학술 연구는 현재까지 이루어지지 않았다. 그리하여 본 논문은 기존의 도기 관련 자료들을 비교 정리하고, 나아가 현시점에서 대순진리회의 문장과 이 문장을 담고 있는 도기의 상징과 의미를 어떻게 바라보아야 할 것인지 대하여 언급하고자 한다. 물론 이는 상징이 가지는 다의성(多意性)으로 인한, 문장의 의미에 관한 하나의 관점을 제안하고자 하는 것이다. 본 글에서 대순, 삼원(三圓), 사대(四大), 중앙의 도안을 각각 제시하였는데, 이렇게 상정할 때 기존의 도기 해석보다 더 풍부한 상징성을 가질 수 있고, 그에 따른 대순사상적 의미를 도출해 낼 수 있음을 살펴보았다. 이러한 시도로 인하여 기존과는 구별되는 상징과 의의를 살펴보자면, 첫째로 문장의 중심을 이루는 원을 지원(地圓)이나 인원(人圓)이 아닌 대순의 중심이라고 언급하여, 천지인의 중심과 그 근본을 이루는 무극과 태극의 상징성을 도출해 내었다는 것이다. 둘째는 중앙에서 토(土)의 상징을 인원과 분리해 그 중화와 조화의 상징을 사대절로 드러내었다. 셋째는 원에 있는 돌기의 방향성을 통해 그 의미를 도출한 것이다.

본 논문에서는 영화 후반 제작 단계의 편집 및 시각특수효과(Visual Effects; VFX) 과정 사이에서 효율적인 변환 작업을 위한 eXtensible MarkUp Language (XML) 기반 메타데이터의 활용 방법을 제안한다. 국내 영화의 후반 작업 단계에서 편집과정으로부터 시각특수효과과정으로 데이터를 제공할 때 Cineon DPX 혹은 TGA와 같은 영상 시퀀스 형태의 작업 방식을 취한다. 이러한 방식은 결과적으로 렌더링 과정을 두 번을 거치게 되어 처리 시간과 데이터 용량의 증가를 초래한다. 반면 XML을 이용한 방식은 메타데이터를 사용하여 렌더링 과정을 대체하기 때문에 시간과 데이터 용량을 줄일 수 있다. 또한 이 방법은 다양한 편집 및 시각특수효과 프로그램에서 지원이 가능하고, 영상편집 관련 분야뿐 만 아니라 영상의 콘텐츠 정보, 그리고 온라인 콘텐츠와의 융합도 가능한 장점이 있다. 이를 웹 기반의 XML의 구조로 발전시키면 영상뿐만 아니라 다양한 다른 매체와의 융합도 가능할 것이다. 본 논문에서는 영화 제작 환경에 적합한 메타데이터 저장 방식과 저장된 메타데이터를 공유하여 편집과정과 시각특수효과과정에서 작업 효율을 높일 수 있는 방법을 제시한다.

실세계는 불연속성의 물체와 지표면의 개념으로 공간적인 모델링이 된다. 생성된 데이터 모델은 벡터와 래스터 형태로 표현된다. 비록 공간에 관련된 문제를 해결하기 위해서 단지 한 종류의 데이터를 사용해도 충분한 경우가 있기는 하지만 일반적으로 GIS는 다양한 형태의 데이터를 사용하게 된다 최근에는 GIS 분야의 발달로 다양한 형태의 데이터 모델이 소개되어지면서 이들 다양한 형태의 데이터를 효과적으로 다루기 위한 요구가 점점 커져가고 있는 추세이다. 지리정보 분야의 표준에 대한 연구를 수행하고 있는 Open GIS Consortium은 다양한 형태의 공간 데이터를 저장하고 활용하기 위해서 GMLJP2(Geographic Mark-Up Language JP2) 포맷을 소개하였다. GMIJP2 포맷은 웨이블렛 영상 압축 기법을 기반으로 하는 JPEG2000(JP2) 포맷을 기반으로 해서 확장성 및 호환성이 좋은 GML 데이터를 압축된 영상 위에 추가한 포맷이다. 이번 논문은 GMLJP2 포맷의 고찰과 다양한 공간데이터를 활용하고 관리하는데 활용될 수 있는 가능성을 검증하고자 한다. 항공사진, 수치지도와 LIDAR 데이터를 변환시켜서 GMLIP2 파일을 성공적으로 생성할 수가 있었다. 또한, GMLJP2 파일을 처리할 수 있는 응용프로그램을 설계 및 구현시켜 단일 파일에서 다양한 형태의 공간데이터를 효율적으로 처리되는 것을 확인하였다.

The spinning apparatus and production of secretory silk from silk gland of the black widow spider, Latrodectus mactans were studied with scanning and transmission electron microscopes. The silk glands were located in seven groups on the spinnerets including each pair of major and minor ampullate, 3 pairs of tubuliform, 1 pair of flagelliform, 2 pairs of aggregate, about 50 pairs of pyriform and over 250 pairs of aciniform glands, respect- ively. Each group of silk gland feeds silk into one of the three spinneret pairs. Secretory silk is synthesized from rough endoplasmic reticulum (rER) of glandular epithelial cells. The secretory silk is transported from toe rER into the secretory vacuoles which are grown up by fusion with the surrounding small vesicles including the secretory silk. The secretory vacuoles, which show a gradual increase in electron density with the process of maturity, are formed without involvement of the Golgi complex, suggesting that they do not play an important role in the processing of the secretory silk. The secretory silk products are released by the mechanism of apocrine secretion, losing part of their cytoplasm. Moreover, another type of silk precursor, possibly protein, appears as granular material, and is also discharged to the luminal cavity.

Recently many studies have been done on the Random Early Detection(RED) algorithm as an active queue management and congestion avoidance scheme in the Internet. In this paper we first overview the characteristics of RED and the modified RED algorithms in order to understand the current status of these studies. Then we analyze the RED dynamics by investigating how RED parameters affect router queue behavior. We show the cases when RED fails since it cannot react to queue state changes aggressively due to the deterministic use of its parameters. Based on the RED parameter analysis, we propose a self-adaptive algorithm to cope with this RED weakness. In this algorithm we make two parameters be adjusted themselves depending on the queue states. One parameter is the maximum probability to drop or mark the packet at the congestion state. This parameter can be adjusted to react the long burst of traffic, consequently reducing the congestion disaster. The other parameter is the queue weight which is also adjusted aggressively in order for the average queue size to catch up with the current queue size when the queue moves from the congestion state to the stable state.

This study was conducted to develop a prototype of adjustable desk and chair for students from elementary to high school. The development process started with identifying the problems of existing adjustable desks and chairs that are currently available in the market. The following fundamental design criteria were established and then applied to develop the prototype. The criterion of minimization of production cost yielding lower the market selling price was the most critically considered in view of the school furniture buyers' price-consciousness. Other design criteria used in this development were designing for stable and solid structure, requiring few motions and no tools to adjust, requiring the use of only one hand to adjust, unrestricting the adjustable interval, providing extra space for foot and knee area, reducing weight to move easily, and requiring not to move around for cleaning up floor. To evaluate the performance of the prototype, the adjustability of prototype was specifically compared with both dimensions suggested by KS G 2010(Korean Standards for desks and chairs for students) and current anthropometric dimension in terms of the flexible range of accommodation. Results of this study illustrate that the prototype developed in this study could be accommodated for the both dimensions. As a concluding mark, appropriate adjustable range for various grades and age groups were presented.

This paper gives an overview of HIGIPS design concepts and prototype HIGIPS configuration, and discusses its application to recognition of the 3-D motion of a human arm. HIGIPS which employs the combination of pipeline architecture and multiprocessor architecture, is a high-speed, high-performance and low cost N * M multimicroprocessor parallel machine, where N is the number of pipeline stages and M is the number of processors in each stage. The algorithm to recognize the motion of a human arm with a single TV camera was developed on personal computer (NEC PC9801 series). As a constraint condition, some simple ring marks are used. Each joint of the arm is attached with a ring mark to obtain its centroid position when the arm moves. These centroid positions in the three-dimensional space are linked at each of the successive pictures of the moving arm to recover its overall motion. This algorithm takes about 2 seconds to process one image frame on the general-purpose personal computer. This paper mainly discuses how to partition this algorithm and execute on HIGIPS, and shows the speed up. From this application, it is clear that HIGIPS is an efficient machine for image processing and recognizing.

The Korean Auto industry has developed remarkably over the past 30 years. In 2000 alone, Korea produced 3.11 million vehicles, and the number of vehicles registered surpassed the ten million mark. As the number of vehicles registered in Korea has increased, yew after you, a rising number of cars have been scrapped. In 2000, a total of 455,592 automobiles were scrapped, up dramatically from only 101,158 in 1989. The system for handling of ELV(End-of-Life Vehicles) in Korea is governed by the "Motor Vehicle Control Act". The Act places the responsibility for vehicle scrapping directly on the vehicle owners. h vehicle owner can only can eel a vehicle registration after he gets a certificate from an authorized vehicle dismantler showing that his vehicle was properly scrapped according to the law. The take-back rate of ELV reaches nearly 100% in Korea. The vehicle scrapping process in Korea is very similar to those in other countries. fluids such as fuels and oils are first removed, and recyclable parts are collected and separated. Engines and transmissions are dismantled and recycled for use as raw material. Plastics, which are not easily reused, are generally treated as industrial wastes. The "Motor Vehicle Control Act" prohibits reuse of certain parts in order to guarantee the safety of the used auto parts. However, some restrictions on the reuse of auto parts have recently been eased to promote recycling. In this paper, additionally, car recycling policy of the foreign countries such as Japan, Germany and EU were reviewed.

The Internet banking service, through which customers process their banking-related works, was introduced in July 1997. The service has since spread quickly, and as of the end of June 2000, just one year after its introduction into Korea, its subscribers numbered 1.23 million people. This figure is ten times larger than the 120,000 subscribers recorded over the six months period up to the end of 1999. In addition, since the end of June 2000, subscriptions on average increase by more than 10,000 a day, and by the end of December 2000, it is expected to pass the 3 million mark. There has been no empirical study conducted on the invigorated Internet banking's status and its services. Therefore, this research is designed to conduct a survey on the Internet banking service status, to conduct actual transactions from the viewpoint of customers and then make a empirical evaluation of it. This will indicate directions for improvement and development of the domestic Internet banking service. We have evaluated ten areas of the Internet banking service including financial service, customers service, users'convenience, and system safety. As of the end of June 2000, 18 out of 20 commercial domestic banks are providing an Internet banking service, and we have conducted evaluations of all these banks. The evaluation is divided into ten categories with 100 points as a maximum score. These are then classified into six grades AAA, AA, A, BBB, BB and B. The outcome of this evaluation was featured in the major domestic journals, and the banks, acknowledging the value of the report, declared that they would adopt it as their criteria for evaluation.
