Bank Guarantee system is commonly used as useful financial instruments to support various overseas and domestic business activities by providing bank guarantees. Therefore, it will be able to develop as a useful socio-economic useful system. However, some procedural problem can arise from the processes under demands for payment. Therefore, it is very important to review the requirements of the demand for payment and compliance standard for the examination of a presentation under the guarantee system. It is necessary to examine main issues under the revised URDG 758. The URDG introduced the same examination principle of "need not be identical to, but shall not conflict with' as that of UCP 600. The main changes of the URDG 758 like this imply the mitigation of the compliance standard for examination. So, This paper is to provide a comparative study of the regulations and laws for the examination standard and propose their implications and practical notes under bank guarantee system. For this purpose, this study will be examined the practical and legal issues focusing on the relative regulations of the revision URDG 758. It will also be reviewed and compared with the URDG, ISP98, UCP 600 and so on.

We intended to show some basic requirements for spectrum analysis of electroencephalogram (EEG) by visualizing the differences of the results according to different values of some parameters for analysis. Spectrum analysis is the most popular technique applied for the quantitative analysis of the electroen- cephalographic signals. Each step from signal acquisition through spectrum analysis to presentation of parameters was examined with providing some different values of parameters. The steps are:(1) signal acquisition; (2) spectrum analysis; (3) parameter extractions; and (4) presentation of results. In the step of signal acquisition, filtering and amplification of signal should be considered and sampling rate for analog-to-digital conversion is two-time faster than highest frequency component of signal. For the spectrum analysis, the length of signal or epoch size transformed to a function on frequency domain by courier transform is important. Win dowing method applied for the pre-processing before the analysis should be considered for reducing leakage problem. In the step of parameter extraction, data reduction has to be considered so that statistical comparison can be used in appropriate number of parameters. Generally, the log of power of all bands is derived from the spectrum. For good visualization and quantitative evaluation of time course of the parameters are presented in chronospectrogram.

분산 멀티미디어 환경에서 교재 제시를 위한 미디어내${\cdot}$미디어간 동기화는 전송 데이터의 지연과 손실 및 미디어별 전송 특성 등과 같이 비동기 오차로 인해 미디어들간의 정확한 시간 관계성을 보장하기가 매우 어렵다. 미디어내 동기화는 표현률에 영향을 받기 때문에 네트워크 지연으로 인한 미디어 도착률이 비정상적일 때 지터 현상이 발생한다. 그리고 각각의 미디어 스트림에서 지터의 누적된 결과로 미디어간 스큐가 발생한다. 이런 현상은 원거리 교육에서 네트워크 지연으로 인해 학습자의 내용 인식에 혼란을 야기시키고, 송${\cdot}$수신측의 효율적인 상호 작용을 제공하지 못하고 있다. 따라서 본 논문에서는 미디어 또는 하나 이상의 미디어 사이에서 시간 관계성의 요구 사항을 유지함으로써 네트워크 지연으로 인한 문제점을 해결할 수 있다. 또한 표현률에 영향을 받는 미디어내 동기화 방법을 제안하고, 원격 교육을 위한 교재 제시 시스템을 구현하였다.

Intestinal duplication is a rare congenital anomaly. The diagnostic approach is difficult because of the differences in its location and clinical presentation. To evaluate the diagnostic as well as the therapeutic approaches in children, the medical records of 20 patients with intestinal duplications which had been operated upon from July 1980 to October 2002 were analyzed, retrospectively. The range of age was from 1 day to 11 years. The variables, such as age, sex, clinical presentation, diagnostic method, localization, anatomic type, treatment, complication, and combined anomalies were analyzed. Most of the cases were presented as incidental finding. The majority of the duplications except hindgut were cystic type. Treatment included segmental intestinal resection, excision of the lesion without intestinal resection, and septotomy. Seventy-five percent of the patients were detected before 1 year of age. The anatomic type of the lesion was closely related with its location. The cases of hindgut were almost always tubular type except 1 case. Clinical presentation was related to age, location, and anatomic type. There were no specific diagnostic methods. Perfect localization and application of appropriate operation are the most important requirements for successful treatment.

A museum represents a country's history, culture and life. With the development of science and technology, museum is no longer simply a space that concentrates on display and management of the collection but a space for education that visitors can directly experience and feel interest. The purpose of the present study is firstly through theoretical approach and research to grasp the status quo of the exhibition of the National First Level museums located in Beijing, which is the capital city of the People's Republic of China. Secondly, by analyzing the themes of exhibition and the exhibition presentation methods, it is aimed at finding out the problems of the status of museums in China so as to seek the requirements and the direction of improvements. Through this research, it is confirmed that in order to induce more active exhibition participation, the museums should expand the number of direct experience style exhibition presentation methods. Also, the museums in China need technical introduction of new cutting-edge exhibition medium so as to meet emotional demands of spectators and make the most ideal experience environment. Furthermore, it is confirmed that the development of new exhibition themes and the improvement of the museums in aspect of management and operation are necessary.

Beneficiary must present all documents stipulated in the Credit. If the documents conform in all respects with the terms and conditions of the Credit, beneficiary has a right to payment from an issuing or confirming bank. And banks must examine all documents presented by beneficiary for taking up the documents. If the documents appear on their face not to be in compliance with the terms and conditions of the Credit, banks may refuse to take up the documents. But standard for compliant documents with the terms and conditions of the Credit in the UCP or Section 5 of UCC is unclear. Because UCP Article 13(a) provides merely that banks must examine all documents stipulated in the Credit ${\cdots}$ to ascertain whether or not they appear, on their face, to be compliance with the terms and conditions of the Credit. ${\cdots}$ Documents which appear on their face to be inconsistent with one another will be considered as not appearing on their face to be in compliance with the terms and conditions of the Credit. Also UCC Section 5-108(a) provides merely that. ${\cdots}$ an issuer shall honor a presentation that, ${\cdots}$ appears on its face strictly to comply with the terms and conditions of the letter of credit. All problems are not resolve with easy by these regulations. Accordingly, I examined requirements for compliant documents with the terms and conditions of the Credit on the basis of the UCP and cases. To analyse this, I divided into three requirements ; (1) Completeness, (2) Regularity, (3) Linkage.
