The existing model transformation researches have focused on various transformation format supports, scalability or applicability of model transformation mechanism itself or how it is easy to understand transformation rules without verification of the transformation. In this paper, as defined in the MDA based model transformation studies of a graph based mode transformation, and how to perform model transformation verification through transformation profile with model property information and redefining graph comparison algorithm. A case study in AGG tool is presented to illustrate the feasibility of the model transformation verification with model property information.

고종원 ( Jong-won Ko ),송영재 ( Young-jae Song ) 한국정보처리학회 2008 한국정보처리학회 학술대회논문집 Vol.15 No.2

국내 표준무선인터넷플랫폼인 WIPI 에 대한 확장성 연구는 미들웨어 차원에서 여러 연구로 진행되었지만 이 논문에서는 애플리케이션 레벨에서 MDA 에서의 모델변환을 적용, 다른 플랫폼에서의 애플리케이션을 쉽게 WIPI 플랫폼으로 포팅할 수 있는 방법을 제안한다. 도메인 모델의 식별과 메타모델 정의, 그리고 변환규칙 등을 정의하여 XML 및 XSLT 를 이용한 모델변환을 수행한다. 또한 서로 다른 개발 플랫폼에서의 API 매핑과 WIPI 기반 도메인 제약조건 등을 인식하고 향후 제한적이지만 제안사항을 적용한 모델변환도구의 개발과 테스트 기능 지원으로 연구를 진행한다..

소프트웨어 개발 효율성을 높이기 위해 모델 차원에서의 재사용성을 목적으로 한 OMG의 MDA 의 모델 변환기술에 대한 최근연구는 입력모델과 목표모델 간의 그래프 비교를 통한 변환모델에 대한 검증방법이나 그래프 패턴을 이용한 모델검증은 두 모델의 구조를 단순히 Version Tree 형태로 모델을 나타내고 있으며, 단순노드와 에지를 통한 상호 그래프 모델을 비교함으로써 실제 설계모델 자체의 구조적인 특징이나 모델이 지니는 다양한 형태의 정보를 정확히 나타내기에 한계점이 많다. 본 논문에서의 모델속성정보를 정의하여 그래프 변환 모델을 다시 재정의하고 기존의 그래프 기반 비교 알고리즘을 개선하여 소프트웨어 모델의 의미정확성을 검증할 수 있는 메카니즘을 제안하고 있다. 또한 AGG 변환도구를 이용한 사례연구를 통해 UML 클래스다이어그램과 RDBMS모델 간의 그래프기반 모델변환에서의 의미정확성을 보장하기 위한 그래프변환규칙 및 그래프 모델속성정의를 적용한다. The existing model transformation tools have focused on various transformation format supports, scalability or applicability of model transformation mechanism itself or how it is easy to understand transformation rules without verification of the transformation model generated through mainly model transformation engines. we supported verification mechanism of transformation model with model property information, dynamic analysis in this paper. Therefore, by increasing reliability of model transformation and furtherapplying test issues on the software development process to the software mode at software design phase. A case study in AGG tool is presented to illustrate the feasibility of the model transformation verification with model property information.

고종원 ( Jong-won Ko ),송영재 ( Young-jae Song ) 한국정보처리학회 2004 한국정보처리학회 학술대회논문집 Vol.11 No.1

임베디드 시스템에 탑재될 자바가상머신을 기능별 모듈로 컴포넌트화 하여 이식될 플랫폼의 요구사항에 맞추어 재구성한다면 컴포넌트 기술의 장점인 소프트웨어의 재사용과 재구성을 통한 빠르고 신뢰성있는 자바가상머신 개발이 가능하다. 이러한 자바가상머신 컴포넌트 재구성을 위한 컴포넌트 모델의 정의 및 명세를 위한 지원도구가 필요하며, 명세도구의 지원 하에 보다 시각적인 컴포넌트 구성 및 각 명세요소 정의를 바탕으로 한 자바가상머신 컴포넌트의 재구성에 요구되는 여러 제약조건이나 각 컴포넌트 간의 관계정의 등이 명세 되어질 수 있다. 또한 임베디드 시스템이 가지는 실시간 속성에 대해서 정의하여 이를 명세도구를 통해서 속성명세 및 설계 시에 예측성을 지원하기 위한 WCET 계산이나 우선순위 정의 등을 명세할 수 있다. 따라서, 본 논문에서는 명세방법을 제안하고 실시간 속성 중심의 자바가상머신 컴포넌트 명세도구를 설계하고 구현하였으며, 기존에 제안된 내장형 실시간 컴포넌트 개발도구와 비교하였다.

박은숙 ( Eun Suk Park ),고종원 ( Jong Won Ko ) (사)한국마이스관광학회(구 한국컨벤션학회) 2016 MICE관광연구 Vol.16 No.1

As the usage of tour information service through smartphone is on its tendency of increase, selecting products by using mobile phone is receiving enormous attention as a new market. Following research is to analyze how the tour-information, which utilize the application of mobile phone while it’s broadly available, practically affects consumers, and how did the acquisition of information via these application systems of mobile phone is boosting up the satisfactory outputs. Assaying, standing on the basis of the survey, age groups between 20’s to 50s’ are used to select and analyze the courses, which they’ll be traveling, using mobile phones. In other words, every attention is concentrated on the functions of mobile phone, diversification of its application systems, and quick alteration in tour-information, since industries using mobile phone is rapidly growing and people’s taste in spending and traveling is drastically mobile-centered. Through this, considering the tendencies, we can see that for the growth and development in tourism industry; sight-seeing developers, travel agencies, application developers; research in depth is needed as tour, mobiles, since various ages of people depend on mobile phone and also regarding the fact that utilizing one’s mobile phone is essential in making decisions in traveling.

백수진(Su-Jin Baek),고종원(Jong-Won Ko),송영재(Young-Jae Song) 한국콘텐츠학회 2011 한국콘텐츠학회논문지 Vol.11 No.8

초기에 예측하지 못한 환경에 대응하기 위한 핵심 요소로 비즈니스 활동 모니터링이 주목받고 있다. 그러나 기존의 이벤트 처리 기반 모니터링 시스템과 실시간 조기 경보 비즈니스 활동 모니터링은 고정된 환경을 가정하여 설계 시 룰 기반으로 표현하여 경보 여부를 결정하거나, 이벤트 속성값이 입력되는 매시점마다 측정하여 경보를 내리게 된다. 따라서, 복잡한 환경에서의 새로운 외부 상황 문제에 대한 발생 범위와 심각한 정도 등을 판별하는데 한계가 있으며, 추상화하지 못한다. 본 논문에서는 외부에서 발생하는 새로운 시나리오의 서비스 요구를 기존의 실행중인 모니터링을 통해 지속적인 서비스 제공을 보장하도록 목표 시나리오를 이용한 비즈니스 프로세스 외부상황 평가 모델을 제안하였다. 외부 상황에 따른 새로운 요구사항을 목표 시나리오 기반으로 분석을 하고, 유사 프로세스 모델을 찾아 유사도와 연관도를 합하여 파악한 뒤 프로세스를 사전에 중단 시키거나 원하는 방향으로 변경하도록 한다. The scope of the problems that could be solved by monitoring and the improvement of the recognition time is directly correlated to the performance of the management function of the business process. However, the current event-managing monitoring system and the real-time advanced alarming business monitoring system decided whether to apply warnings or not by assuming a fixed environment and showing expressions based on the design rules. Therefore, there is a limit for distinguishing the range of occurrence and the level of severity in regard to the new external problems occurring in a complicated environment. Such problems cannot be abstracted. In this paper, evaluation model of business process contextual situations using goal scenario is suggested to provide constant services through the current monitoring process in regard to the service demands of the new scenario which occurs outside. The new demands based on the outside situation are analyzed according to the target scenario for the process activities. Also, a similar process model is found and identified by combining similarity and interrelationship. The process can be stopped in advance or adjusted to the wanted direction.

제주도 중산간 개척에 따르는 농업경영 진단

고종원,오현도 제주대학교 1970 논문집 Vol.2 No.-

This study has been conducted to investigate and diagnose the adaptability, profitability and marketability of the agricultural crops grown in the reclaimed land of the mid-mountain region of Cheju-Do, with the purpose of furnishing both the government officials and the farmers with scientific data and information for a more rational management of their farming. 1. Adaptability(Crop-growing Conditions) The mid-mountain area has more rain fall and less fertile soil than the coastal farm lands long under cultivation, Because of these unfavorable conditions, the former cannot reach the latter in the production rate. The following table shows the percentage of the yield, as compared with that of the coastal farm lands. Upland Rice : 82.0% Sweet Potato : 76..0% RapeSeed : 83.6% Beer Barley : 69.5% White Potato: 82.0% Chinese Cabbage : 82.4% 2. Profitability The most profitable crop rotation was to plant "rape" first and then Chinese cabbages. This kind of crop rotation was found to earn 7,154￦ for 500 pyung of the mid-mountain land a year. The rotation of rape and sweet potatoes ranked second and earned area 6,787￦ for the same acreage. When the earning amount of each individual crop was examined, rape-seed was the first among commercial crops. It earned a net profit of 4,343 for a year, while the sweet potatoes, standing second, earned 2,440￦. 3. Marketability In 1968, the total output of sweet potatoes amounted to 250,000 tons and still, most of them were sold as raw materials for starch and for alcohoI. But in 1969, the Government remeved the ban of imorting "molasses", a better material for manufacturing alcohol. Moreover, the Government is pushing forward a plan for the "ethylene,, alcohol production in Korea, with the aim of starting it in 1971. These two factors becloud the prospect of the demand for sweet potatoes. Unless new markets are exploited, any drive for production increase should be withheld. In 1968, Cheju-Do produced about 7,000 tons of rape-seed, nut of which 4,270 tons were sold through tne regular channel, i. e. through agricultural cooperatives, for industrial processing and 2,000 tons were consumed for home use. But this means that several hundred tons of rape-seed could not be used or consumed during the year and that the production exceeded the demand. Therefore one urgent task will be to acquire and exploit new markets for both rape-seed and sweet potatoes.
