        The purpose of this study was to analyze attack skills and scores in 8 weight classes of female Taekwondo athletes who participated in the semi-final and final matches(48 athletes) in the 14th Asian Games(2002, Busan). The 14th Asian Games was chosen for this study because it is in these games that the rules were revised to a variable scoring system. The results obtained from this analysis were as follows; 1. Korean female athletes: No significant difference was found in attack frequency in the light weight class and the heavy weight class. The attack frequency in the light weight class was shown to be in the following order: momtong-dolryeochagi(217 times), naraechagi(48 times) and dichagi(15 times). The attack frequency in the heavy weight classwas shown to be in the following order: momtong-dolryeochagi(263 times) and tchikeachagi(15 times). 2. Foreign female athletes: No significant difference was found in attack frequency in the light weight class and the heavy weight class. The attack frequency in the light weight class was shown to be in the following order: momtong-dolryeochagi(555 times), naraechagi(32 times) and dichagi(12 times). The attack frequency in the heavy weight class was shown to be in the following order: momtong-dolryeochagi(555 times), tchikeachagi{35 times) and naraechagi(35 times). 3. There is a significant difference in attack frequency in the light weight group of Korean female athletes and foreign female athletes, Between groups, in case of quick body attack, such as momtong-dolryeochagi and naraechagi, the frequency of korean athletes was shown to be higher and scores obtained were higher. In case of high score face attack, such as eolgul-dolryeochagi and tchikki, the frequency of foreign atheletes was shown to be higher 4. There is a significant difference in attack frequency in the heavy weight group of Korean female athletes and foreign female athletes, Between groups, in case of quick body attack, such as momtong-dolryeochagi and naraechagi, the frequency of Korean athletes was shown to be higher and the foreign female athletes' eolgul-dolryeochagi and dwitchagi score rates were shown to be the higher.

      • 신경회로망을 이용한 호 접수제어기

        허정석,양성룡 울산대학교 1993 공학연구논문집 Vol.24 No.1

        B-ISDN의 전송 및 교환 기법으로 정착되고 있는 ATM망의 폭주제어를 위하여, 신경회로망을 이용한 호 접수 제어기를 설계한다. 신경회로망을 이용한 호 접수제어는 가입자가 선언한 트래픽 기술인자의 불확실성에 대한 정보를 제어기가 가지고 있기 때문에, 실제 트래픽이 호 설정요구시 협약된 트래픽의 특성과 다소 상이하더라도 견고성(Robustness) 있는 트래픽 제어를 할 수 있는 장점을 가지고 있다. 본 연구에서는 신경회로망 제어기를 보다 효율적으로 학습시킬 수 있도록 두가지 학습 패턴 테이블(호 연결 요청 수락 패턴 테이블과 호 연결 요청 거절 패턴 테이블)을 이용하는 학습 알고리즘을 제안한다. 또한 모의 실험을 통하여, 제안한 신경회로망 호 접수 제어기의 성능을 분석한다. This paper describes a call admission controller by neural network to control the traffic in ATM network for service quality. Because the information of the traffic descriptor declared by users has a characteristic of uncertainty, the design and implementation of efficient controller in the network is very difficult task. The proposed ATM call admission controller by neural network is adaptive and easy to implement. We use two learning table for efficient learning of back-propagation neural network in controller. The performance of the proposed call admission controller is evaluated by simulation, and the results are compared with those of the other control technique.

      • CORBA 기반 망관리 시스템 통합에 관한 연구

        윤채운,김명균,허정석 울산대학교 1999 공학연구논문집 Vol.30 No.2

        통신망이 커지고 복잡해짐에 따라 통신망 관리는 더욱 중요해지고 있다. 이러한 통신망을 효율적으로 관리하기 위해 국제 표준화 그룹인 ITU와 ISO는 CMIS/CMIP 기반의 OSI망 관리 모델 [1]을 표준화하고 IAB에서는 SNMP [7] 기반 망관리 모델을 표준화하였다. 이들 망관리 모델은 통신망 요소들의 관리에는 효율적이지만 복잡한 망들의 관리나 서비스 관리에는 많은 문제들이 있다. 이러한 문제들을 해결하기 위해 본 논문에서는 분산 객체 지향 기술인 CORBA[3]를 이용하여 기존의 망관리 시스템들을 통합하기 위한 방법에 대해 기술한다. CORBA 기반 통합 망관리 구조를 제시하고 CORBA와 OSI망관리 모델사이의 관리정보 및 관리기능 변환 기능을 위한 CORBA/CMIP 게이트웨이 구조를 제시한다. 또한 COBRA 관리자에서 OSI객체들을 접근하기 위� 기법과 OSI객체에서 발생하는 이벤트를 CORBA 관리자에 전달하기 위한 기법들에 대해 기술한다. Network management systems become more important as the communications networks evolve larger and more complicated. For the efficient management of the communications networks, the international standard organizations, ITU and ISO, have standardized OSI network management model [1] based on CMIS/CMIP, and IAB has proposed SNMP [7]as the Internet management model. The traditional management models are efficient in managing simple communications netwrks, but have many problems in managing complicated networks and services. To solve those problems, this paper proposes an integration method of network management systems based on CORBA [3] which is a distributed and object-oriented technology. We describe an integrated network management architecture based on CORBA/CMIP gateway. The CORBA/CMIP gateway converts the management systems. We also describe how the CORBA managers access the OSI managed objects and how the events occurred in the OSI managed objects are delivered to the CORBA managers.

        선택적 자궁동맥 색전술을 이용하여 자궁경부 임신을 보존적으로 치료한 1예

        허정수,이기수,정봉진,윤정신,정의중,황진석,권중혁 대한산부인과학회 2002 Obstetrics & Gynecology Science Vol.45 No.5

        자궁경부임신은 자궁경관 내에 수정란이 착상하는 자궁외임신의 한 형태로서, 드물고 생명을 위협하는 경우이다. 자궁경관은 주로 섬유 조직으로 구성되며 자궁경부임신은 경관 조직 내 노출된 혈관으로부터 대량 출혈을 유발할 수 있다. 과거에는 자궁경부임신이 생명을 위협하는 출혈로 인해 흔히 자궁 적출술을 시행하였다. 최근에는 생식력 보존을 희망하는 경우에 있어서 소파 수술 전에 자궁동맥 색전술을 포함한 몇 가지 보존적 치료가 가능하게 되었다. 저자들은 자궁경부임신을 소파수술 전 선택적 자궁동맥 색전술을 시행하여 성공적으로 치료한 1예를 간단한 문헌 고찰과 함께 보고하는 바이다.

        Levels of common salivary protein 1 in healthy subjects and periodontal patients

        Heo, Seok-Mo,Lee, Sol,Wang, HongTao,Jeong, Jeong Hyeok,Oh, Sang Wook Korean Academy of Periodontology 2016 Journal of Periodontal & Implant Science Vol.46 No.5

        Purpose: Human saliva, as a vital part of the immune defense system, contains a number of distinct proteins and peptides. Recently human common salivary protein 1 (CSP1) has been identified as an abundant salivary protein and may play a role in promoting the binding of cariogenic bacteria to salivary pellicles. However, nothing else is known regarding the role of CSP1 in periodontology. The aim of this study was to quantify and compare CSP1 levels between healthy subjects and periodontal patients. Methods: This controlled clinical study was conducted in periodontally healthy individuals and patients with chronic periodontitis Chonbuk National University Hospital, with Institutional Review Board approval. Whole saliva samples were collected from 36 healthy subjects and 33 chronic periodontitis patients and analyzed. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immune blotting were conducted to ensure that anti-CSP1 monoclonal antibody (mAb) binds to CSP1 in human saliva. A sandwich enzyme-linked immunosorbent assay (ELISA) system was house-fabricated using mAb-hCSP1#14 and mAb-hCSP1#4 as a capture and a detector mAb, respectively. The CSP1 concentrations in saliva from 36 healthy subjects and 33 periodontal patients were quantified using the CSP1 sandwich ELISA system, and the results were analyzed using the Student's t-test. Results: Immunoblot analysis using mAb-hCSP1 as a probe confirmed that CSP1 in human saliva existed as a single band with a molecular weight of approximately 27-kDa. The quantification of CSP1 concentrations by CSP1 ELISA showed that the median values (25th to 75th percentiles) of periodontal patients and healthy subjects were 9,474 ng/mL (range, 8,434.10,139 ng/mL) and 8,598 ng/mL (range, 7,421.9,877 ng/mL), respectively. The Student's t-test indicated the presence of a statistically significant difference between the 2 groups (P=0.024). Conclusions: The presence of a significant difference in CSP1 levels between healthy subjects and periodontal patients suggests that CSP1 may be a potential biomarker for the detection or screening of periodontitis patients.
