Rahim Lotfi 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.6

Design pattern is a mechanism to show experience in object-oriented design, as well as an appropriate solution which has been provided by experts for particular problems and which can be used over and over throughout the design. Using design patterns helps improve software quality and reusability. There are different patterns for development of data source (database, file, array, etc.) systems but most of them have features that are not appropriate for code generation. We seek in this research new patterns for development of data source systems that can accelerate the development of such systems and reduce costs and are appropriate for code generation as well. This article deals with challenges related to prototype, singleton and MV* (MVC, MVP, MVVM) patterns. As a solution, we will propose two patterns called MVC+ and MVC++ as well as a tool called LCG for code generation. We compare the proposed patterns with similar patterns in terms of efficiency. MVC+ and MVC++ are appropriate for model-driven architecture, code generation and the development of windows form applications and web applications.

윤소미,임기훈,박철형 제주대학교 교육과학연구소 2020 교육과학연구 Vol.22 No.1

The purpose of this paper is to strength of lower extremity by the event characteristics of secondary school athletes. The subjects were 123 male elite athletes (7 sports) from Jeju middle school (7 schools, 65 students) and high school (11 schools, 58 students), and measured the subject's height, weight and Maximal Voluntary Contraction (MVC) and Rate of Force Development (RFD). As a result, first, there was a positive correlation between MVC and RFD. Second, there was a statistically significant difference in the strength levels of similar event sports at the MVC. Third, the anaerobic event showed statistically significant higher MVC than the aerobic event. Fourth, the higher the MVC than the average level, the more significant effect on the anaerobic event. At present, athletic performance is the most important indicator for predicting a athletes's performance. Understanding the characteristics of each event and applying appropriate training programs are essential elements for systematically nurturing student athletes and maximizing future development. 본 연구는 증등학교 운동선수들의 종목별 특성에 따른 하지 근력을 분석하는데 목적이 있다. 제주지역 중학교(7개교, 65명) 및 고등학교(11개교, 58명) 남자 엘리트 운동선수(7개 종목) 123명을 연구대상자로 선정하였으며, 신장, 체중, 하지 근력(자발적 최대근력(Maximal Voluntary Contraction, MVC) 및 힘 생성 비율(Rate of Force Development, RFD))을 측정하였다. 연구 결과 첫째, MVC와 RFD에서 정적 상관관계가 나타났다. 둘째, 유사종목별 근력 수준은 MVC에서 통계적인 유의한 차이가 나타났다. 셋째, 무산소성 종목이 유산소성 종목에 비해 MVC가 통계적으로 유의하게 높은 것으로 나타났다. 넷째, MVC가 평균 수준보다 높을수록 무산소성 종목에 유의한 영향을 미치는 것으로 나타났다. 운동능력을 통해 선수의 경기력을 예측하고, 종목별 특성을 이해하여 적합한 훈련프로그램을 적용한다면, 학생선수들을 체계적으로 육성하고 향후 발전 가능성을 극대화하는데 도움될 수 있을 것이라 기대된다.

Recently, human embryonic stem (hES) cells have become very important resources for ES cell basic research, cell replacement therapy, and other medical applications; thus, efficient cryopreservation methods for these cells are needed. This study examined whether a newly developed minimum volume cooling (MVC) vitrification method, which was tested through cryopreservation of sensitive bovine oocytes, can be used for freezing hES cells. Feeder-free cultured hES cell (MB03) colonies were mechanically dissected into several small clumps following enzymatic treatment. We compared the freezing efficiency of a slow-cooling method using a cryo-module (0.4-0.6C/min, 20-30 clumps/vial) and MVC vitrification using a modified 0.5-ml French mini-straw designated as a MVC straw (>/min, 10 clumps/straw) After thawing, in vitro survival of hES cell clumps was higher for MVC-vitrified cells (80.8%, 97/120) than for slow-cooled cells (38.2%, 39/102). Further, the proliferation rate of surviving MVC-vitrified cells was similar to that of control hES cells from 2 weeks after thawing. In addition, vitrified-thawed hES cells demonstrated a normal karyotype, were positively immunostained for surface marker antibodies (AP, SSEA-4 and TRA-1-60) and the Oct-4 antibody, and could differentiate into all three embryonic germ layer cells in vitro. This result demonstrates that hES cell clumps can be successfully cryopreserved by a newly developed MVC vitrification method without loss of human cell characteristics.

In this paper, we propose a flexible GGOP prediction structure to improve coding efficiency for multi-view video coding. In general, reference software used for MVC uses the fixed GGOP prediction structure. However, the performance of MVC depends on the base view and numbers of B-pictures between I-picture(or P-picture) and P-picture. In order to implement the flexible GGOP prediction structure, the location of base view is decided according to the global disparities among the adjacent sequences. Numbers of B-pictures between I-picture(or P-picture) and P-picture are decided by camera arrangement such as the baseline distance among the cameras. The proposed method shows better result than the reference software of MVC. The proposed prediction structure shows considerable reduction of coded bits by 7.1%.

장예진 ( Ye-jin Jang ),백종호 ( Jong-ho Paik ) 한국인터넷정보학회 2024 인터넷정보학회논문지 Vol.25 No.1

코로나19의 발생으로 인한 방역 및 소독업무의 중요성이 높아짐에 따라 소독원을 모집하고 싶은 소독사업자와 일하고 싶은 소독원의 수요가 증가했지만, 구인·구직은 쉽지 않은 실정이며, 소독 업무에 대한 자동화와 업무를 효율적으로 관리할 수 있는 시스템이 필요하다. 따라서 본 논문에서는 O2O 소독 서비스 시스템을 MVC 패턴을 사용하여 설계하고, MySQL, Ejs/BootStrap 뷰, Node.js를 통해 구현한다. 또한, AWS 클라우드 서비스와 연동하여 사용자가 언제 어디서나 시스템을 사용할 수 있게 한다. 제안한 O2O 소독 서비스 시스템을 통해 국내 소독방역 시장의 인력 채용의 어려움을 해결하고, 기존의 비효율적인 소독 업무 프로세스 개선을 기대한다. Due to the outbreak of COVID-19, the domestic disinfection and quarantine market has grown, and the demand for disinfection operators who want to recruit disinfectants and disinfectants who want to work has increased, but it is not easy to find jobs. In addition, there is a need for a system that can automate or efficiently manage work by hand-recording and writing a disinfection record for disinfection work. Therefore, in this paper, an O2O disinfection service system is designed using the MVC pattern and implemented through MySQL, Ejs/BootStrap view, and Node.js. Additionally, it connects with AWS cloud services so users can use the system anytime, anywhere. Through the proposed O2O disinfection service system, we hope to solve the difficulties of recruiting personnel in the domestic disinfection station market and improve the existing inefficient disinfection work process.

MVC 프레임 워크를 사용한 VoiceXML 다중 뷰 편집기의 설계 및 구현

유재우,염세훈 한국음향학회 2004 韓國音響學會誌 Vol.23 No.5

본 논문에서는 음성 웹 언어인 VoiceXML의 작성 효율을 향상하기 위한 다중 뷰 편집기를 설계 및 구현하였다. VoiceXML 다중 뷰 편집기는 다중 뷰를 제공하기 위해 MVC (Model-View-Controller) 프레임워크을 이용하였다. MVC 프레임워크를 이용한 다중 뷰 편집기는 핵심 자료구조인 모델과 인터페이스인 뷰, 모델과 뷰를 제어하기 위한 제어기로 구성된다. MVC 프레임워크에서 모델은 추상 구문 트리와 추상 문법으로 구성되며 뷰는 역파싱 규칙과 역파서로 구성되고 제어기는 명령어 처리기와 트리 조작기로 구성된다. VoiceXML 다중 뷰 편집기는 문서의 구조, 내용, 흐름을 동시에 보여주어 기존 XML 편집기의 단점을 극복할 수 있다. MVC 프레임워크가 적용된 VoiceXML 다중 뷰 편집기는 여러 편집기를 통해 동시에 다양한 편집 뷰 (View)를 제공함으로써 사용자에게 음성 웹 문서 작성의 편의성을 제공하여 효율을 높일 수 있으며 여러 개의 뷰가 하나의 모델을 가짐으로써 편집기들의 무결성을 보장하도록 하였다. In this paper, we design and implement a multiple-view VoiceXML editor to improve editing efficiency of the VoiceXML. The VoiceXML multiple-view Editor uses a MVC framework to support multiple views and paradigm. Our multiple-view editor consists of Model. View and Controller using MVC framework. A model, core data structure. is constructed of abstract syntax tree and abstract grammar. A view. user interface. is formalized in unparsing rules and unparser. A controller. to control model and view. is made of command interpreter and tree handler. The VoiceXML multiple-view editor overcomes a drawbacks of existing XML editors by showing document structure and context concurrently. as well as document flows. Our VoiceXML multiple-view editor. which MVC framework has been applied, provides various editing views concurrently to users. Thereby. it supports efficient and convenient editing environments for voice-web documents to users and it guarantees transparency of editors. as various views have a same consistent model.

Study of Mobile Application Development using MVC Framework

Ram Naresh Thakur,U. S. Pandey,Jyotir Moy Chatterjee 한국디지털융합학회 2019 IJICTDC Vol.4 No.2

Mobile Application should be secure, portable, cost-effective and be of good quality. The architecture choice is very important to ensure the quality of the application over time and to reduce development time. Model-View-Controller (MVC) is a very useful for developing Application. It has become the most powerful and leading Programming Architecture for developing a large scale of Application. MVC Developers can trust on the framework that is widely accepted as solutions for recurring problems and used to develop flexible, reusable and modular Application. In this study we investigate the advantage of using MVC Framework when building Mobile Application available on difference devices. In this study compares and contrasts two platforms, iOS and Android Devices, and discusses how to apply the MVC Framework in order to minimize the inherent differences between the platforms.

서비스 기반 모바일 어플리케이션의 MVC 아키텍처 및 적용 사례연구

이호중(Ho Joong Lee),라현정(Hyun Jung La),김수동(Soo Dong Kim) 한국정보과학회 2010 정보과학회 컴퓨팅의 실제 논문지 Vol.16 No.11

최근 들어 모바일 디바이스는 편리한 통신기능과 휴대성을 제공할 뿐 아니라, 다양한 어플리케이션을 실행할 수 있는 장비로 활용되고 있다. 그러나, 모바일 디바이스의 자원 제약성으로 인해 복잡도가 높은 어플리케이션에는 한계를 가지고 있다. Model-View-Control(MVC)아키텍처는 다양한 어플리케이션 설계에 널리 사용되고 있지만, 서비스 기반의 모바일 어플리케이션의 특징을 모두 반영하지 못한다. 본 논문에서는 고품질 고성능의 서비스 기반 모바일 어플리케이션 설계를 위해, 기존의 MVC 아키텍처를 확장한 효과적인 모바일 앱 아키텍처 모형과 적용 기법을 제시한다. 이를 적용하면, 자원제약성 문제를 크게 해소하고, 복잡도가 높은 어플리케이션 개발이 가능해 진다. Mobile devices are utilized not only for communications but also for running applications. However, applications with high complexity could not be deployed on mobile devices which have inherent resource limitation. While Model-View-Control(MVC) is commonly used in designing applications, it does not address mobile device specific characteristics. In this paper, we propose effective mobile application architectures which extend the conventional MVC architecture, to develop mobile application with high performance while remedying their resource constraints.
