This paper describes implementation of the core DSM-CC UU interface. It briefly describes the reference model for the DSM-CC and related standards that should be reviewed for the implementation. The Common Object Request Broker Architechture, Revision 2.0 (CORBA 2.0) is sued as a remote procedure call (RPC) scheme for the UU Interface. Entire system was implemented with C++ on Windows NT platforms. The implementation procedure has been decomposed ito two tasks. The first task is to implement the Naming Service for service navigation. The Naming Service is one of the CORBA Services that extend the core CORBA specification. A client GUI is implemented for easy navigation among various services. The second task is to construct multimedia server and client for a Video-on-Demand (VoD) system. MPEG-2 Transport Stream is transported via ATM AAL5 using the Windows Socket 2.2 ATM extension API. A GUI enables the user to navigate the service domain and select a program. After the selection the user can control the MPEG-2 stream with VCR-like buttons.

Background/Aims: Transoral incisionless fundoplication (TIF) is an accepted anatomic treatment for gastroesophageal reflux disease in selected patients. In this report, we analyze our institution's programmatic allocation of resources during the safe implementation of TIF as a new procedure. Methods: A retrospective analysis of all patients who underwent TIF from January 2020 to February 2021 at our institution was performed. The process of initially allocating the operating room (OR) with overnight admission and postoperative esophagram for added safety, and subsequently transitioning TIF to the endoscopy suite (ES) as an outpatient procedure was described. Patient safety and outcomes were evaluated during transition. Results: Thirty patients who underwent TIF were identified. The mean age was 51.2±16.0 years. TIF was performed in an OR in nine patients (30%) and 21 (70%) in the ES. All the OR patients were admitted overnight and had routine esophagogram. In contrast, four (19%) from the ES group required clinically-indicated admission and three (14.2%) required esophagram. The mean procedure duration was significantly lower in the ES group (65.7 min vs. 84 min, p=0.02). Conclusions: A stepwise, resource-efficient process was described that allowed safe initiation of TIF as a new technique and its effective transition to a fully outpatient procedure.

`집합 제한 논리 언어`는 `집합 이론`을 프로그래밍에 도입한 언어이다. 본 논문은 A. Dovier 연구팀이 제안한 집합 제한 문제 풀이(solver) 절차를 소개하고, 이 절차가 논리 언어 Prolog 상에서 어떻게 구현 가능한 지를 보인다. 이 절차는 `다시쓰기 규칙(rewrite rule)`으로 표현되어 있는데 이 표현의 특징은 일반 프로그래밍 언어가 표현하기 힘든 비결정적 규칙 적용(nondeterministic rule application)과 수학적 변수 (mathematical variable)를 사용한다는 점이다. 본 연구에서는 이들 특징이 Prolog 언어에서 제공되는 비결정적 제어 (nondeterministic control), 논리적 변수(logical variable) 및 리스트(list) 자료구조의 사용으로 쉽게 구현 가능함을 보인다. 본 연구의 구현은 다음과 같은 의의를 가지고 있다. 첫째 본연구는 이 언어의 모든 기능을 완전하게 구현하였다는 점이다. 둘째 본 연구에서는 이 언어의 구현 방법을 누구나 알기 쉽게 기술하였다는 점이다. 셋째 기존의 구현이 상업적 Prolog인 SICStus Prolog를 사용하여 구현한 것과는 달리 본 구현은GNU GPL(General Public License)을 가지는CIAO Prolog를 사용하여 구현하였기 때문에 누구나 자유롭게 사용할 수 있는 점이다. 넷째 본 연구에서 개발된 소스 코드는 공개 소프트웨어이기 때문에 누구나 자유롭게 사용, 수정 및 배포할 수 있다는 점이다.

This paper presents the implementation procedure of encoding and decoding algorithms for Tornado code that can provide fault tolerance for storage and transmission system. The degree distribution satisfying heavy tail distribution is produced. Based on this distribution, a good random irregular bipartite graph is attained after plenty of trails. Such graph construction is proved to be efficient, and the experiments also demonstrate that the implementation obtains good performance in terms of decoding overhead.

In this paper, details of the design and implementation of a voice source simulator using Simulink and Matlab are discussed. This simulator is an implementation by model-based design concept. Voice sources can be analyzed and manipulated through various factors by choosing options from GUI input and selecting pre-defined blocks or user created ones. This kind of simulation tool can simplify the procedure of analyzing speech signals for various purposes such as voice quality analysis, pathological voice analysis, and speech coding. Also, basic analysis functions are supported to compare the original signal and the manipulated ones.

By operating on many part of a software system concurrently, the parallel processing computers may provide several orders of magnitude more computing power than traditional serial computers. If the Lagrangean approximation procedure is applied to a large scale manufacturing problem which is decomposable into many subproblems, the procedure is a perfect candidate for parallel processing. By distributing Lagrangean subproblems for given multiplier to multiple processors, concurrently running processors and modifying Lagrangean multipliers at the end of each iteration of a subgradient method,a parallel processing of a Lagrangean approximation procedure may provide a significant speedup. This purpose of this research is to investigate the potential of the parallelized Lagrangean approximation procedure (PLAP) for certain combinational optimization problems in manufacturing systems. The framework of a Plap is proposed for some combinatorial manufacturing problems which are decomposable into well-structured subproblems. The synchronous PLAP for the multistage dynamic lot-sizing problem is implemented on a parallel computer Alliant FX/4 and its computational experience is reported as a promising application of vector-concurrent computing.

This study introduced various theories and related studies on the evaluation of informal environmental education programs and suggested an evaluation procedure for them. The case study on the procedure and the result of Non-indigenous, Invasive Species Management/Education program evaluation was provided, which was conducted by Cornell University in cooperation with Cornell Cooperative Extension, The Nature Conservancy, and Finger Lake Land Trust. The procedure model that was used in this study was based on Herman et al. (1987) and slightly modified for the environmental education program evaluation. The procedure and results indicated that the implementation of NIS management/education program properly accomplished it's intended goal and objectives. This study also specifically described its implications for the evaluation of environmental education programs in informal settings.

Despite much attention of strategy implementation, there is rarely a study focusing on the ways to evaluate the strategy implementation competence. Therefore, based on broad literature review, we suggested a simple model and procedure to evaluate the technology strategy implementation competence based on importance-Performance Analysis (IPA). The proposed model applied to the case of 'Company A' in order to examine the feasibility. We grasped the importance of strategic direction by surveying the employees in 'Company A', and also measured relative importance and performance of critical technology strategy implementation factor. By analyzing the results of the survey, we can identify the barriers to implementing the technology strategy in 'Company A'.

This paper describes the issues associated with the real-time implementation of G.723.1A dual-rate speech coder on a TMS320VC5402 DSP. Firstly, the main features of the G.723.1A speech coder and the procedure involved in the implementation using assembly and C languages are discussed. Various real-time implementation issues such as memory/MIPS tradeoffs are also presented. For fixed-point implementation, we converted the ITU-T fixed-point ANSI C code into TMS320VC5402 code in the bit-exact way through verification using the test vectors. Finally, as the result of implementation, we present the MIPS and memory requirement for the real-time operation.

소프트웨어에 대한 저작권 분쟁에서 통상 감정절차를 거치는데 이 과정에서 상당한 기간이 소요되고 있는 점은 신속한 재판받을 권리를 구현함에 있어 장애로 지적된다. 이에 실무적으로 소프트웨어 감정 절차를 간이절차로 운영하고자 하는 논의가 오랜 기간 있어왔다. 기존의 논의는 주로 감정절차에 투입되는 자원을 줄이는 방식에 따르고 있는데, 이러한 방식은 필연적으로 감정을 통하여 도출되는 결과에 차이를 가져올 수밖에 없다. 이에 간이절차의 본질적 성격 및 재판 과정에서 소프트웨어 감정의 역할을 중심으로 기존 논의되던 소프트웨어 감정의 간이절차 운영에 대해 검토하였다.
