노민기,하지아,안성진 한국융합보안학회 2002 융합보안 논문지 Vol.2 No.2

그리드는 지리적으로 흩어져 있는 이종의 자원들을 고속 네트워크로 연결하여 협업하기 위한 기반구조이다. 그리드 응용의 수행되기 위해서는 먼저 네트워크의 안정성과 신뢰성이 보장되어야 함으로 네트워크 자원들은 관리되어야 한다. GMA는 대규모 분산된 자원의 모니터링을 위한 효과적인 구조를 제안한다. 본 논문에서는 GMA를 기반으로 실제적이고 전체적인 네트워크 관리를 위한 웹 기반 그리드 네트워크 관리 시스템을 설계하였다. 그리드 네트워크 관리 시스템은 여러 분산된 관리 시스템을 스스로 유지시키면서 연결할 수 있어야 한다. LDAP 인증을 이용하여 시스템 접근에 대해 관리자 인증을 수행하여 그리드 네트워크 관리 시스템의 안정성을 보장한다. Grid is a infrastructure to connect heterogeneous resources that are scattered over areas with high-speed network and to cooperate with each other. To carry out Grid application, first, network resources should be managed, since the network has to be safe and reliable. GMA suggests an effective architecture for monitoring of resources that are scattered over a wide area. In this paper, basing on GMA, Grid network management system based on web for practical and general network management is designed. Grid network management system has to operate and connect various distributed management system. Using LDAP authentication, as one access system, Grid network management system maintain stability.

노민기,이찬균,장민석,석우진 한국통신학회 2019 KNOM Review Vol.22 No.2

The paradigm of science and technology and R&D system changes from the existing form of independent research to community research which transmits and stores large-capacity data generated from observation and experiment to the research site through a high-speed network. Network-dependent advanced research is improves form of collaboration, sharing, globalization. For this purpose, not only the integration of science and IT technology, but also the optimized network infrastructure and technology for real-time sharing of the enormous data is necessary. This paper explains the direction of change through the case of KREONET's network-dependent advanced research and analyzes the technology and network resources supported in each research field. Through this, we propose a network optimization model for each advanced research field with the main data flow and satisfy the network required performance by advanced applications on KREONET. 과학기술·연구개발체계의 패러다임은 기존 단독형 연구수행 형태에서 변화하여 관측과 실험에서 발생한 대용량 데이터를 고속 네트워크를 통해 연구현장에 송수신하고 저장하며, 이를 각 연구자 (기관)의 목적에 맞도록 활용하는 형태로 변화하고 있다. 네트워크형 첨단연구는 협업화, 공유화, 공용화, 글로벌화 하는 형태로 발전하고 있으며, 이를 위해 과학기술과 IT기술의 결합 뿐 아니라, 점점 거대화되는 데이터의 실시간 공유와 활용을 위해 최적화된 네트워크 환경과 기술 간의 융합이 필요하다. 본 논문에서는 국가과학기술연구망 (KREONET)의 네트워크형 첨단연구의 사례를 통해 변화의 방향을 제시하고, 데이터흐름을 분석한다. 이를 통해 주요 데이터흐름과 용량에 따른 네트워크 최적화 모델을 제시하였으며, 네트워크형 첨단연구에서 요구되는 실시간성 연구수행 성능을 충족하였다.

노민기 ( Min Ki Noh ),안성진 ( Sung Jin Ahn ) 한국컴퓨터교육학회 2009 컴퓨터교육학회 논문지 Vol.12 No.2

대용량 연구자원과 실시간 데이터 전달을 필요로 하는 대용량 어플리케이션은 현재의 인터넷 환경보다 더 안정적이고 성능이 우수한 네트워킹 환경을 요구하고 있다. 최근의 글로벌 연구망에서는 이러한 어플리케이션의 요구를 충족하기 위해 람다 네트워킹 기술과 자원할당 시스템의 활용에 초점을 맞추고 있다. 본 논문에서는 성능과 안정성이 우수한 람다네트워킹의 장점을 반영하기 위해 기존 DRS(Dynamic Right-Sizing) 모델을 수정하였다. 아울러, 융합형 NRPS(Network Resource Provisioning System) 모델에 본 논문의 수정된 DRS 모델을 적용한 고성능 람다 네트워크의 설계방안을 제시한다. Large-scale applications, that needs large-capacity R&D resources and realtime data transmission, have demanded more stable and high-performance network environment than current Internet environments. Recently, global R&D networks have focuses on utilizing Lambda networking technologies and resource reservation systems to be satisfied with various applications` requirements. In this paper, we modify the existing DRS (Dynamic Right-Sizing) model to reflect various advantages in terms of the stability and high-capacity of Lambda network. In addition, we suggest the design methodology of high-performance Lambda network, which can integrate NRPS (Network Resource Provisioning System) into our modified DRS model.

상·하악 제2대구치 발치를 동반한 II급 부정교합의 치료

노민기(Min-ki Noh) 대한치과교정학회 2021 대한치과교정학회 임상저널 Vol.11 No.2

If a third molar has satisfactory shape and position, it can be a good substitute of the second molar. A 21-year-old woman had been referred to the clinic. She wanted to get an orthodontic treatment before prosthetic treatment. To minimize prosthetic treatment, the maxillary and mandibular third molars were planned to substitute the second molars. After second molar extraction, the maxillary third molar erupted with a slight mesial angulation without any intervention, which was corrected with minor adjustment using fixed appliance. The mandibular third molar was successfully protracted by loop mechanics using stainless steel wire with a root-mesial moment.

긴 레버암과 골격성 고정원을 이용한 돌출입 환자의 설측 교정 치험례

노민기(Min-ki Noh) 대한치과교정학회 2023 대한치과교정학회 임상저널 Vol.13 No.4

27-year-old woman came to the clinic. Her chief complaint were lip protrusion and lower anterior teeth crowding. She wanted a lingual orthodontic appliance on the maxilla and a labial appliance on the mandible. Because she had lip protrusion with large overjet, premolar extraction treatment was selected. The retraction wire with a long lever-arm and skeletal anchorage system was applied for torque and vertical control of upper anterior teeth. Moreover, additional over-torque was applied on maxillary anterior teeth during making set-up model to prevent excessive torque loss. After orthodontic treatment, the appearance of the lip protrusion was improved. Angle Class I molar and canine relationship were accomplished. The large overjet of anteriors were improved without excessive torque loss of upper anteriors.

노민기(Min-ki Noh) 대한치과교정학회 2022 대한치과교정학회 임상저널 Vol.12 No.1

A 23-year-old woman with an anterior open bite malocclusion was referred to the clinic. Because she was a skeletal Class II hyperdivergent pattern with retruded mandible, molar intrusion was planned to correct the open bite as an effective strategy. Newly designed modified bonded TPA was applied to intrude the maxillary molars without the excessive vertical change of the incisors which was in normal range. Molars were successfully intruded bilaterally without any buccolingual tilting. The autorotation of the mandible was accompanied with molar intrusion, which contributed to the improvement of facial esthetics.
