MPEG-21 멀티미디어 프레임워크 환경에서의 툴 서버의 구조와 기능을 제안한다. MPEG-21의 목적은 멀티미디어 콘텐츠의 전자적 생성, 배포, 거래를 투명하게 이용할 수 있도록 상호 운용 가능한 멀티미디어 프레임워크를 제공하는 데에 그 목적이 있다. MPEG-21을 구성하는 주 요소로서 DIP(Digital Item processing)와 DIA(Digital Item Adaptation)가 있다. DIP의 역할은 디지털 리소스에 메타 데이터 정보를 구조화하여 표현할 수 있는 DI(Digital Item)를 생성하고 소비하는 기능을 가진다. DIA는 사용자가 터미널 또는 네트워크 특성에 맞게 고유의 DI를 적응시켜서 보내주는 기능을 한다. 툴 서버(Tool server)는 DIP 또는 DIA로부터 필요로 하는 구동 툴을 검색하여 적합한 툴을 제공해 주는 기능을 한다. DIA가 DI 자체를 사용자 요구에 맞게 적응시켜 소비시켜 주는 일을 한다면 툴 서버는 사용자 터미널 환경에 맞추어 DI를 생성 또는 소비하는데 적합한 소프트웨어 툴을 찾아서 다운로딩하고 생성 또는 소비할 수 있게 해 주는 기능을 한다. 전체 논문의 구성은 다음과 같다. 1장에서 MPEG-21 멀티미디어 프레임워크에서 툴 서버의 필요성과 역할을 알아본다. 툴 서버가 가져야 할 요구 사항은 2장에서 논한다. 3장에서는 툴 서버의 기본 구조와 각 모듈별 기능을 살펴본다. 그리고 3장에서는 툴 서버를 DIP 또는 DIA와 연동했을 때 상호간에 이루어지는 시나리오를 설명한다. 또한 시나리오를 토대로 간단히 테스트용 툴 서버를 구현한다. 마지막 4장에서 결론을 맺는다.

The purposes of this research are to examine the effects of muscle relaxation to the rheumatoid arthritis patients' physiological, psychological, and social adaptation, and to verify that the technique Is an effective tool for improving the patients' adaptation. This research utilized a qusi-experimental design that compares the pre-experiment measures and the post-experiment measures. The subjects of this study were 37 out-patients who were diagnosed for rheumatoid arthritis in P university hospital and K clinic between September 12, 1993 and November 30, 1993. The experimental group consisted of patients treated on Monday, Wednesday and Friday. The control group consisted of patients treated on Tuesday, Thursday and Saturday The pre-experimental survey utilized the following tools. The physiological adaptation was measured by a graphic rating scale for pain and activity of daily living. The psychological adaptation was measured by Zung's depression scale and Rosenberg's self-esteem scale : and the social adaptation was measured by Derogatis' psychosocial adjustment scale. The experimental group received muscle relaxation treatment for 15 minutes per day for the period of 2 weeks, the control group received no treatment and had quiet time. The post-experiment measurement was carried out similar to the pre-experiment survey, SPSS $PC^+$ is used to analyze the collected data. The reliabilities of the measurement tools were examined by Cronbach's ${\alpha}$ coefficients. The homogeneities between the experimental and control groups were tested by t-test and chi-square test, hypotheses were tested by t-test. This research found that the general characteristics between the groups were statistically homogenious. The physiological, psychological, and social adaptation between the groups in the pre-experimental survey were also statistically homogenious. The results of this research can be summarized as follows : 1. Concerning the Physiological adaptation, the experimental group showed a statistically lower pain score than the control group. Thus, muscle relaxation was effective to relieve the pain of rheumatoid arthritis patients (t=-2.95, p=.006). 2. Concerning the psychological adaptation, the experimental group showed a statistically lower depression score than the control group. Thus, muscle relaxation was effective to reduce the patient's depression(t=-4.00, p=.001). 3. Concerning social adaptation, the experimental group showed a statistically higher score for the health maintenance and disease control than the control groups. Thus, muscle relaxation was effective for the health maintenance and disease control (t=2.09, p=.004). This research showed that the muscle relaxation is a nursing intervention that can promote the physiological, psychological and social adaptation of the rheumatoid arthritis patients in terms of short-term and cognitive changes. However, more fundomental changes in behavior and long-term physiology could not be found through such a short-term relaxation treatment.

본 논문에서는 OFDM 시스템의 성능의 중요한 부분을 차지하는 FFT 알고리즘의 성능 비교와 제안된 SRFFT를 설계/구현 및 검증으로 우수성을 확인한다. 대부분의 OFDM 통신시스템에서는 단일 입력, 단일 출력형태를 사용하므로 SRFFT 적용이 매우 비효율적일 수 있다. 그러므로 OFDM 시스템에 적합한 구조의 필요성이 요구되고 기존에 나와 있는 SRFFT 구조를 변형하여, 단일 입력, 단일 출력의 Pipeline 구조를 갖는 FFT / IFFT 블록을 구현한다. 제안된 SRFFT는 Matlab과 Synthesis 및 Simulation Tool을 이용하여 유효성 확인과 기존 알고리즘과의 성능을 비교하고 동작을 검증하였다.

This paper presents the role and its function of Tool server. MPEG-21 means multimedia framework for delivery and consumption of multimedia which is being discussed in ISO/IEC 21000. A view of MPEC-21 aims to define multimedia framework to enable transparent use of multimedia resource across a wide range of networks and devices used by different communities. MPEG-21 will enable all-electronic creation delivery and trade of digital multimedia content and transparent usage of various content types on network device. Therefore, we can provide access to information and services from almost anywhere at anytime with various terminals and networks. In order to support multimedia delivery chain that contains content creation, production, delivery and consumption, we need many standards(elements) for identify, describe, manage and protect the content. Thus, we define Digital Item Player(DIP), Digital Item Adaptation(DIA) server and Tool server as primary objects of MPEG-21 multimedia framework. DIP provides a function which creates and consumes Digital Item(DI) as a kind of a digital object by user. A DI contains both media resources and metadata including rights information. DIA server deals with the usage environment description schema of the user characteristics, terminal and network characteristics and natural environments. DIA server adapts the original DI to the usage environment description sent from the terminal and transmits the adapted DI to the terminal. Tool server searches for a tool requested from DIP or DIA and downloads the best tool to DIP or DIA server. In this paper, we present how Tool sewer is organized and is used among 2 primary objects. The paper is structured as followings: Section 1 briefly describes why MPEG-21 is needed and what MPEG-21 wants. We see requirement that tool server must equip functionally in section 2. The proposed tool server,its structure and its functionality are presented in section 3. Section 4 explains a scenario that tool server transmits tool to DIP and shows the experimental result. The paper concludes in section 5.

Prokaryotes encode clustered regularly interspaced short palindromic repeat (CRISPR) arrays and CRISPR-associated (Cas) genes as an adaptive immune machinery. CRISPR-Cas systems effectively protect hosts from the invasion of foreign enemies, such as bacteriophages and plasmids. During a process called 'adaptation', non-self-nucleic acid fragments are acquired as spacers between repeats in the host CRISPR array, to establish immunological memory. The highly conserved Cas1-Cas2 complexes function as molecular recorders to integrate spacers in a time course manner, which can subsequently be expressed as crRNAs complexed with Cas effector proteins for the RNA-guided interference pathways. In some of the RNA-targeting type III systems, Cas1 proteins are fused with reverse transcriptase (RT), indicating that RT-Cas1-Cas2 complexes can acquire RNA transcripts for spacer acquisition. In this review, we summarize current studies that focus on the molecular structure and function of the RT-fused Cas1-Cas2 integrase, and its potential applications as a directional RNA-recording tool in cells. Furthermore, we highlight outstanding questions for RT-Cas1-Cas2 studies and future directions for RNA-recording CRISPR technologies.
