  • In the area of speech processing, raw signals used to be presented in 2D format and different kinds of algorithms use the format to solve their problems. However, such kinds of presentation methods have limitations to extract characteristics from the signal, even though the algorithms are quiet good. The basic reason is that not much information can be detected from the 2D signal. Strange attractor in the field of chaos theory provides the 3D presentation method. In the area of the recognition problem, signal construction method is very important because good features can be detected from a good shape of attractors. This paper discusses a new presentation method that can be used to construct strange attractor in a different way. Normal strange attractor uses time-delay idea while the new method uses time-delay and vector average. This method provides us good information to be applied to speaker recognition problem.

  • 멀티미디어 연출을 재생하는 단말기나 통신망이 다양해짐에 따라 멀티미디어 데이터를 저장하고 있는 근원지의 데이터 서비스 품질과 재생하는 목적지의 서비스 품질이 다른 경우가 많이 발생하고 있다. 이러한 멀티미디어 연출을 재생하기 위해서 근원지의 데이터를 목적지에서 요구하는 재생 서비스 품질에 맞추어 변환하는 과정이 반드시 필요하다. 문제는 하나의 멀티미디어 연출 프로그램이라도 그것이 재생되는 단말기나 통신망의 환경에 따라 변환 경로가 달라져야 한다는 점이다. 즉 고정된 변환 경로를 사용할 수 없고 재생되는 단말기나 통신망이 정해지면 그에 맞는 변환 경로를 다시 생성해야 한다는 점이다. 본 논문은 주어진 변환 자원과 통신망을 고려하여 근원지 데이터를 목적지에서 요구하는 재생 서비스 품질에 맞게 변환하는 경로를 찾는 알고리즘과 그 경로가 목적지에서 요구하는 서비스 품질에 맞게 재생 가능한지를 검사하는 방법을 제시한다. 본 논문이 제시한 변환 경로를 생성하는 알고리즘은 변환 자원과 변환 규칙을 문맥 자유 문법(Context Free Grammar)으로 기술 할 수 있도록 함으로 변환 경로를 컴파일러 기법을 이용하여 생성할 수 있도록 하였다. 그리고 재생 가능성을 검사하기 위하여 변환 과정에서 소요되는 시간과 지연 등을 계산하는 방법과 요구하는 시간 내에 이루어 질 수 있는지 검사하는 방법을 제안하였다. 그리고 이러한 방식을 실험실에서 개발한 Transcore라는 멀티미디어 스트림 엔진과 VIP라고 하는 저작도구에 구현하였고 간단한 시나리오에 적용한 결과를 마지막으로 기술하였다.

  • This paper described the effect of subjective approach in case of the human sensibility experiments. The procedure is proceeded subjectively. Human faces are selected as the image presentation media. Pleasant and unpleasant images are selected directly by examiner, And also the image presentation system, which is executed with a computer and has the square-type black box monitor equipment, is manufactured. Images are presented with the step-variation time interval technique. questionnaire test and EEG signal detection data are analyzed. The analysis parameters are a “frequency band integral value” and a “band differential variation ratio”. he results show the high sensibility and fast response. The fact that image presenting repetition alleviates is verified.

  • In this paper, I examined the trends of standardization and electronization of trade documents and SWIFT network. Also, I reviewed on emerging electronic documentary credit for electronic payment and electronic presentation of documents. New international trade customs and practices are being established and changed as a result of the growth of the Internet and other on-line networks. At the same time there is increasing pressure to move from existing paper-based documentary credit to electronic documentary credit. Several projects devoted to development of an electronic letter of credit infrastructure have recently been proposed such as Bolero, SWIFTNet, UNeDocs and eUCP, etc. Yet, little can be done until the presentation process is electrified between traders and banks. Also, interbank communication of letters of credit has long been electronic, mainly through the SWIFT. However, it is not functioned between applicant and beneficiary, although the solution of SWIFTNet has recently been developed. The Banking Commission of International Chamber of Commerce established a working group consisting of experts in the related fields to prepare the appropriate rules as a Supplement to UCP 500 for Electronic Presentation: eUCP. The eUCP will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. Some problems of electronic presentation under the eUCP, exist such as format, presentation of electronic records and the way of beneficiary's notice for completeness under the Article e5 if more than one record is to be presented electronically by third parties. Therefore, it is encouraged to provide more detailed guide for eUCP Article e5.

  • In the Spring of 2000, the Banking Commission of the ICC decided to appoint a working group to draft a supplement to the UCP 500 to clarify the position regarding electronic presentation under a documentary credit. Provisions was drafted to supplement its existing rules for documentary credit, that is, UCP 500. These new provisions known as Supplement to UCP 500 for Electronic Presentation was approved by the ICC Banking Commission at the beginning of November 2001 and came in force as of 1 April 2002 The eUCP covers matters such as definitions of key terms such as electronic record, electronic signature, format, paper document, received. An eUCP Credit must specify the formats in which electronic records are to be presented and if not, electronic records may be presented in any format. Electronic records may be presented separately and need not be presented at the same time. The purpose of this paper is to understand the main substance of eUCP and to facilitate the introduction of electronic letter of credit by studying the problems and revision of eUCP and new electronic UCP. The main substances of eUCP are electronic address as place for presentation of electronic records, flexibility of the formats of electronic records to be presented, endowment of the notice of completeness of presentation to the beneficiary, one electronic record satisfying one or more originals or copies of an electronic record, the electronic records to be examined including the electronic record at the hyperlink to an external system or the referenced system, no remark as to the time period for the examination of documents. The Roles of eUCP are the Promotion of the Electronic Trade, the Supply of Basis on the Uniform Rules for Electronic Letter of Credit, the introduction of Electronic Trade Model. The characteristics of eUCP are a supplement to the UCP, no address of any issues relating to the issuance or advice of Credit electronically, independence of specific technologies and developing electronic commerce system, that is, Bolero Service. The Problems of eUCP are flexibility of format of electronic record, heavy burden on the side of banks, and the problems regrading the number of presentation, the notice of completeness of presentation, no provision in regard to the time to examine the electronic records, and representation of the electronic records. In the revision of eUCP to resolve the problems, the things to be taken into consideration are as follows; the designation of the format allowing the banks to examine electronically, prohibition of the paper documents, the development of the system receiving the electronic records, the addition of the reception notice on the side of the banks, the setting of the time to examine the electronic records, the construction of the backup system or the dual processing system.

  • Objectives: The aim of this study was to determine the rate of peer-reviewed publication of abstracts presented at the annual meetings of the Turkish Association of Oral and Maxillofacial Surgeons (TAOMS) and to identify the time to publication, subspecialty, and study design. Materials and Methods: All abstracts accepted for presentation at a TAOMS meeting between 2007 and 2009 were identified from a book of abstracts and were searched for publication using PubMed and Google Scholar. The following variables were evaluated: publication rate, type of presentation (oral or poster), time to publication, subspecialty, study design, and name of the journal in which the article was published. Results: A total of 478 abstracts were presented at the TAOMS meetings between 2007 and 2009. Of these, 140 abstracts (29.3%) were subsequently published in peer-reviewed journals, including 38.2% of oral presentations and 26.6% of poster presentations. The mean time from presentation to publication was 22 months. Regarding publication fields, research and emerging technologies presentations had the highest publication rate (100%). With regard to study type, animal study (70.0%) and basic research (55.0%) had the highest publication rates. Conclusion: Only 29.3% of abstracts presented at the TAOMS meeting were subsequently published as full-text articles. This rate was found to be similar to the previously reported publication rates in the field of oral and maxillofacial surgery.

  • Sample presentation, which means how to set samples to an NIR instrument, is very important in Near Infrared (NIR) Spectroscopy. When sample presentation is not suitable for the samples that you use, very good spectra can not be obtained even if you use a sophisticated NIR instrument. In my presentation, various NIR sample presentations for agricultural products such as intact fruits, single grains, vegetable juice and the others will be explained. In case of peaches with thin peel, the fiber optics of Interactance can be used. However, the fiber optics are not suitable for oranges with relatively thick peel. In this case, transmittance method is useful. As for a small sample such as single grains, a specially designed cell is needed. The cell in transmittance mode has been developed and then applied to single kernels of rice and soybean. In this case we also used the fiber optics. As regards liquid type of sample, a cuvette cell made of quartz in transmittance mode is popular. However, it is time-consuming to wash and dry it. In order to compensate this disadvantage the sample presentation using normal test tubes as sample cells have been developed and applied to milk, rumen juice and urine of a milking cow. An individual test tube can be used for each sample if you use the calibration equation with sample cell compensation. The test tube cell has also been applied to spinach juice for determination of undesirable constituents. It is concluded that sample presentation is most important for NIR Spectroscopy.

  • 분산 멀티미디어 문서 시스템은 네트워크로 연결된 여러 서버에 있는 미디어들은 검색하여 제시된 시간 관계에 따라 미디어들을 프리젠테이션한다. 효과적인 프리젠테이션을 위해서는 동기화가 지원되어야 하며, 특히, 분산 환경에서의 프리젠테이션은 네트워크 대역폭과 지연시간 등에 의해 영항을 받기 때문에, 그러한 요소들이 고려되어 동기화가 지원되어야 한다. 본 연구에서는 분산 환경에서 프리젠테이션을 효과적으로 수행할 수 있는 분산 멀티미디어 프리젠테이션 시스템을 제안하고, 프리젠테이션을 위해 미디어들이 각 서버로부터 전송될 때 네트워크의 상태와 자원을 검사하여 그에 따른 변화를 서버에 피드백시켜, 서버로부터 전송되는 데이터의 양을 조절함으로서 동기화를 지원하기 위한 기법을 제안한다. 네트워크의 상태 변화를 효과적으로 파악하여 서버로 피드백하기 위해, 버퍼에 경계점을 설정하여 버퍼를 관리하는 기법과 서버로부터 패킷이 전송되는 시간과 클라이언트에 도착하는 시간의 차이를 체크하는 기법을 함께 사용하고 있다.

  • 프레젠테이션은 제한된 시간에 청중의 행동을 이끌어 내기 위한 의사소통의 한 형태이다. 프레젠테이션은 청중과 소통을 하는 한 가지의 도구로 중요성은 시간이 흐를수록 강조되고 있으며, 능력을 표현하는 방법으로 변화하고 있다. 그렇게 때문에 프레젠테이션을 진행하기 위해서는 다양한 보조도구를 활용한다. 이에 본 논문에서 프레젠테이션에서 활용할 수 있는 모바일 네트워크를 활용한 프레젠테이션 원격 제어 시스템을 설계 및 구현하였다. 기존의 원격 제어 애플리케이션은 네트워크 연결 기능 구현에 오류가 있으며, 사용법에 대한 설명이 없어 사용에 어려움이 있다. 본 시스템은 기존 시스템의 단점을 보완하여 설계 및 구현하였다. 개인용 PC와 스마트폰을 소켓을 통하여 연결 지향적 통신 프로토콜 TCP로 통신한다. PC에 연결하여, 바탕화면 경로의 프레젠테이션 파일 목록을 수집하여 사용자에게 전송한다. 사용자는 수신된 파일 목록에서 프레젠테이션 파일을 선택하여 원격에서 발표 진행을 제어할 수 있도록 하였다.
