소프트웨어 개발비용의 증대로 레거시시스템을 재사용하기 위한 방안과 이를 지원하기 위한 자동화 도구에 관한 관심이 고조되고 있다. 따라서, 본 논문에서는 레거시시스템에 대한 정의와 개념 나아가 등장 배경을 실질적인 시장과 공급사와 기술적 동향을 통해 이를 밝히고 있으며, 레거시시스템을 처리하는 구체적인 개발절차 그리고 구축사례, 평가기준과 이를 효율적으로 처리하기 위한 자동화 도구를 설계하고 개발하였다. 또한, 본 논문에서 제시하는 LM(Legacy to Modern System) 지원도구를 활용하여 레거시 시스템을 분석하고 후보 컴퍼넌트를 추출하여 정제한 다음 저장하여 재사용하는 과정을 구현하였다. 본 LM지원도구를 레거시 시스템의 마이그레이션에 적용할 경우 소프트웨어 재사용의 효과를 통해 비용절감, 개발기간 단축 나아가 기존의 지적재산을 승계하는 효과를 기대할 수 있다. Due to increased software development cost, interest about the method and automated tool for reusing legacy system have been running high. Therefore, In this study, it proves the definition, concept and also background of legacy system by showing real market and technology trend. Automation tool is designed and developed to handle the concrete development methodology, procedure and reference. Also, we implemented the process that analyze the legacy system and extract, refine, store and reuse the candidate components by using LM(Legacy to Modern System) supporting tool presented in this paper. If LM supporting tool is applied to legacy system migration, we can expect cutting costs, shortening the developing period and succeeding the intellectual property by software re-engineering.

본 연구에서는 기존의 소프트웨어 품질 평가 기술 및 표준화 연구에 대해서 종합적으로 정리하고, 이를 토 대로 요구분석을 통한 소프트웨어 품질 평가 모델을 개발하였다. 또한, 현재 소프트웨어 품질 평가 국제 표준화 동향 에 있어서도 소프트웨어의 품질 평가 국제 표준화 문서 ISO/IEC 9126과 ISO/IEC 14598의 두 문서를 통합하여 ISO/IEC 25000으로 제정하기 위한 내용을 참조하였다. 그리고 사용자 관점의 요구사항을 고려하여 각 분야별 특성을 파악해 모바일 RFID 품질 평가 모델을 개발하고 평가자 관점의 모바일 RFID 시험방법을 개발하여 모바일 RFID 품 질을 향상시키는데 목적이 있다. This study has comprehensively summarized existing research on the technology for evaluating software quality and its standardization. Based on this, the study developed a model for evaluating software quality via needs assessment. Also, in terms of the trend toward international standardization of software quality evaluation, this study has consulted details relating to the combining of two documents on such intranational standardization as the ISO/IEC 9126 and ISO/IEC 14598 and enacting them as a single document, the ISO/IEC 25000. Further, the purpose of this study is to develop a model for evaluating mobile RFID quality based on recognition of the characteristics of each area, after taking into consideration the demands made from the perspective of the user. Another purpose is to improve the quality of mobile RFID by developing a testing method for mobile RFID from the perspective of the evaluator

게임을 제작하는 최대의 목적은 플레이어가 재미있어하는 게임을 만들어 성공적으로 판매하는 것이다. 재미있는 게임을 만들기 위하여 게임의 재미요소를 구분하고 플레이어들의 성향을 정확히 분석해야한다. 본 논문에서는 게임 재미요소를 비교하고 이를 바탕으로 가장 세분화된 재미요소를 선택하여 AHP를 이용하여 요소별 중요도를 정량화하였다. 정량화된 값을 바탕으로 다량의 게임 플레어들이 평가한 재미요소값을 활용하여 게임의 장르별 재미 만족도를 조사하였다. 본 연구의 결과는 게임의 재미 만족도를 위한 평가 시스템으로 활용될 수 있으며, 장르별 게임의 재미 요소 구현에 관한 개발 방향성을 제시하였다. The ultimate purpose of producing game is to make successful sale as making players to be fun. We have to identify fun factors of game and analyze player activities more detail to make fun game. In this paper, we compare game fun factors and select the most detailed one of them and then computed weight factors with AHP method. Based on survey of game players of the selected fun factors, we quantified satisfaction of game fun factors. The result of this paper can be used for assessment of game fun satisfaction and establish game development strategy to implement fun factors according to game genre.

Most of the korean coal seam are so irreguler in thickness steep in slope that there are much difficulties in mechanization of coal seam development From the 1980', Dae han coal cooperation having pushed the business of mechanization of coal development had hard effectivity and productivity The East pit 12 level(-210m in sea level) of this mine was changed 2 1m×2 1m(7′×7′) into 3 3m×2 1m in cross section and also shifted into iron 3 mesh steel arch(GI-100) from timber prop to increase the effectivity of production As a result of this changes, the increase of depth ratio was from 15m per year to 5m per year and the production ratio was also increased to 33% on the other hand, the mechanization of this mine showed 20 percent of decrease in man power and proved to be increased in recovery The temperature of this mine pit was 25℃ in average, 90% of humidity and 0 25% of average CO₂ gas It was confirmed that this mine was running properly according to mining safety regulation

梁海承 조선대학교 기초과학연구소 1988 自然科學硏究 Vol.11 No.1

In Dong-Mine of Hwasooon Coal mines, considerable amount of roks are developed within coal seams by repeated folding with reional metamorophism in sandstone seams. Such condition prevents mechanization of mining operations which has been exercised. Therefore, in this study, sub-level mining method is adapted for rook raise connects the upper and lower level with 45? inclination and sub-level is installed in the middle of blocks every 10M distances. And mono-rail or coolie car was installed for the materials. Another chute was driven for the coal and waste. Such system was maintained from January to October, 1987 with favorable results. The annual deepening ratio was reduced to 4M/Year, the recovery increased 40%, accident rate reduced to 79%, and OMS was increased 30%. Adaptation of sub-level coal mining method for the seams with rooks are developed in Hwasoon Coal Mines.

This study aimed to investigated the temperature and the air ventilation guantity of tunnel which has deepened owing to the increasing coal development. In this experiment, the air ventilation quantity was analysed, and air velocity was measured by the digital rotameter and Taylor anemometer and its result was averaged. The value of ventilation resistance was evaluated by the measurement of pressure difference and showed in the Table 1. And the columnar mercury thermometer was used as the measurement of the temperature of tunnel, in every 50m intervals. The result showed that it was 25℃ in maximum but much less than the value of Korean mine safety regulation.

Three clay types of korean clays were chosen for comparative purposes in surface char-acteristics. The electrophoretic mobility and setting velocity of each clay sample was measured with its suspension. The isoelectric point of the kaolinite type clay was found in the strong acidic region, but other clays showed themselves always charged negatively and of high zeta potential.

This research is to check the results of intake air quantity, outlet air quantity and the temperature of pits which are operating in first, second and third incline of Dong Gan(eastern pit) in Whasoon coal mine. The total intake air volume and it outlet volume measured in this pit was 2.319㎥/min and 2.419㎥/min, respectively. The average operating temperature of this mine was 28℃. The ventilation quantity based upon the required volume of ventilation and temperature was 6.6㎥/min per man by thedretical calculation method and on the other hand, the ventilatin quantity based on the pit temperature was calculated as 642㎥/min. These results means that this mine is properly operating according to the mine safy regulations.
