박용범,진병문,Park, Yong-Bum,Chin, Byoung-Moon 한국정보처리학회 1998 정보처리학회논문지 Vol.4 No.1

프로토콜에 대한 적합성시험을 기술하기 위한 국제 시험 표준 언어인 TTCN(Tree and Tabular Combined Notation)은 추상시험스위트의 전체적인 구조, 시험 목적의 표현 그리고 각 시험 기술 요소에 대한 개념과 표기법을 제공하고 있다. 이 논문에서는 TTCN을 사용하여 프로토콜 시험 규격 즉 추상시험스위트를 기술함에 있어서 추상시험스위트의 각 요소에 대해 고려하여야 할 점을 설명하고, 실제적인 시험 기술 경험을 토대로 시험 적용범위의 검증이 용이하고 사용자에게 많은 정보를 줄 수 있는 시험제약과 시험경우에 대한 명명법을 제안하였다. 또한 이 논문에서는 추상시험스위트를 수행 가능한 형태로 변환하여 시험대상에 대해 적용할 때 실제 환경의 제한으로 인하여 발생할 수 있는 문제점을 분석하고 이를 추상 시험스위트 작성 단계에서 미리 해결하는 방안을 제시하였다. 이 논문에서는 ATM Forum UNI 3.1 신호방식 프로토콜 스택 중 AAL(ATM Adaptation Layer)계층의 부계층인 SSCOP(Service Specific Connection Oriented Protocol) 프로토콜을 대상으로 하여 사례를 제시하고, 이를 바탕으로 TTCN 사용의 문제점을 고찰하고 그 해결 방안을 제시하였다. TTCN(Tree and Tabular Combined Notation), as an international standard, provides a concept and notation to describe a protocol test specification. In this paper, we explain some considerations on each components of Abstract Test Suite and propose naming conventions for Constraints and Test Cases based on the experience of describing Test Suite for real protocol. We also analyze some problems on real application of Test Suite and propose an approach to avoiding such problems in the stage of Test Suite specification. In this paper, we use the SSCOP(Service Specific Connection Oriented Protocol) protocol, that is a sub-layer of ATM Forum UNI 3.1 protocol stack, as an example to proposals on naming conventions on Constraints and Test Cases.

N/A Background: Bronchial asthma is a chronic airway inflammatory disorder involving lymphocyte activation. Lymphocytes express various surface markers upon activation, including CD25 (IL-2 receptor α) on T cells and CD23 on B cells. Objectives : To evaluate whether the surface markers of activated lymphocytes are useful indicators of the disease activity in bronchial asthma. Method: We measured serum sCD25 and sCD23 in 42 patients with mild bronchial asthma, and in 26 normal control, volunteers. They were compared with other markers in asthma(methacholine PC20, pulmonary function, total IgE, blood eosinophil counts). Results : Levels of sCD23 were higher among patients than among normal controls and they correlated significantly with sCD23, and FEV1%, but, not with methacholine PC20. Levels of sCD23 were not higher among patients than among normal controls and did not correlate with methacholine PC20, pulmonry function and total IgE level. Conclusion: It appears that sCD25 is related to airway obstruction in bronchial asthma. But, the clinical implications of these markers should be further examined.

전기철도에 전력을 공급하기 위하여 철도변전소에서는 급전특성상 방면별 급전을 시행하고 있으며, 급전계통에 고장 이 발생하는 경우를 대비한 공통반 차단기와 같은 예비설비와 전차선로 고장 발생 시 고장위치를 찾기 위해 고장점 표정장치 를 설치하여 사용 중에 있다. 그러나, 고장 발생 시 공통반 차단기를 사용하여 급전계통을 운용하는 경우에는 고장점 표정반 과의 인터페이스가 되지 않아 고장위치를 찾는데 어려움이 있다. 본 논문은 이러한 문제점을 해결하기 위한 고장점 표정반 자동절체 시스템을 설계하고 동작 상태를 검증한다. 또한 자동절체 시스템을 공통반 차단기에 설치한 후 검증방법으로 설정 된 24회의 지락시험을 통하여 성능시험을 수행하였으며 고장점 표정장치를 이용하여 기존의 고장위치를 효율적으로 검지하 는 방법을 제시하는 데 있다. A directional feeding method at the railway transformer is applied for supplying the power to the electric railway substations, and the pre-installed facilities with common feeder are utilized in preparation for the failure of feeding system and in finding a fault location in case that the catenary failure occurs. However, it is some difficulty in finding the fault location since there is an interface problem with the facilities when the supplying power system operates. In this paper, Auto Fault Locator Transfer Drive System (ALTDS) is designed to search for the fault location efficiently, and the measuring data are obtained and compared with the KORAIL standards. Further, the ground connection test is accomplished 24 times as the verification method, and it is shown that the methodology provides better performance than the existing traditional one.

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 aims to suggest developing directions of marine sports equipments so that many and more people could get to be interested in marine sports and take part in as twenty first century has arrived. As a result of this research, following conclusions are found. Above all, when it comes to marine resorts construction as a form of developing institutions for marine sports, local characteristics should be considered, and the resort should be environment friendly. When it comes to driving off system, environmental and social conditions ought to be considered. About marine theme park building, it should be developed and operated in order to develop, control, and preserve marine resources, and educational benefits should be considered important, too. Secondly, when it comes to marine resource development, comprehensive measures ought to be searched in order to make the approach easier, and make the most and broad use of utilization. When it comes to marketing, a marketing strategy needs to be sought so that target market users would be chosen so that they could be tempted to the marine land and stay there for a long time.
