소프트웨어 개발 생태계의 변화에 따른 소프트웨어 개발의 다양화 및 Time-to-Market으로 인해 사용자들이 요구하는 소프트웨어 품질수준이 높아졌다. 그러나, 소프트웨어 품질을 향상하는 여러 가지가 방법의 하나로 완벽한 테스트를 통해 가능하다. 하지만, 완벽한 테스트를 수행하는 것은 불가능하다. 이를 해결하기 위해 정형화된 올바른 테스트 프로세스를 적용하여 품질을 높이고자 한다. 본 논문에서는 조직의 테스트 성숙도 수준을 평가할 수 있는 TMMi와 테스트 프로세스를 개선할 수 있는 TPI next의 매핑을 기반으로 조직의 테스트 성숙도 측정과 함께 테스트 프로세스 수준 향상을 위한 가이드를 제공하고자 한다. 이를 위한 절차로 TMMi(level2)와 TPI next의 매핑, 비/공통 요소 추출을 통해 조직의 테스트 프로세스 개선을 위한 가이드를 제공하고자 한다.

신뢰성 기술은 제품이 고장 없이 일정기간 사용할 수 있게 하는 기술로 시장점유율과 고객만족을 높이는 효과적이고 전략적인 필수 요소이다. 검사시점의 적합성에 대한 평가가 아닌 제품 및 시스템의 설계에서부터 폐기까지의 제품수명주기에 대한 신뢰성 평가를 다루는 제품의 신뢰성인증과 신뢰성경영시스템 인증 확보가 시급한 과제이다. 이를 위한 제품 수명의 평균과 분산을 효과적으로 관리할 수 있는 신뢰성 식스시그마 기술개발과 확보가 중요 현안과제이다. 정규분포를 가정한 대부분의 품질경영시스템에서의 식스시그마 접근법은 비정규 분포를 따르는 신뢰성특성과 실험계획기법 등을 고려해야 하는 신뢰성 식스시그마에서의 적용의 한계가 많다. 본 연구에서는 품질혁신 방법론인 식스시그마 기법을 토대로 신뢰성경영시스템에서 맞는 식스시그마 구축의 방향성을 제시하고자 한다.

The quality of the casting process generates the largest source of defects in the manufacturing process, so its management is a key factor in productivity and quality evaluation. Based on the results of factor analysis, correlation analysis, and regression analysis with process data, this study aims to optimize the machine learning model to reduce the defect rate and verify the data suitability for smart factories.

This study was carried out to investigate the quality characteristics of commercial breakfast cereals. The results showed that as water absorption index (WAI) increased, water soluble index (WSI) decreased. WSI has an effect on Bowl life, so Bowl life became longer as WSI enhanced. The size, shape and texture of breakfast cereals were also affective factors of their Bowl life. The quality describing terms of breakfast cereals were surveyed and the terms were classified to brittleness, roasted nutty taste, sweetness, hardness and aftertaste, especially brittleness was the most important quality determining terms among these. Significantly, sweetness had positive correlationship with roasted nutty taste. Overall eating quality had positively correlationship with color and roasted nutty flavor, and negatively with pain in mouth, adhesiveness and additive taste.

본 연구에서는 정보시스템의 품질향상을 위하여 정보시스템 감리결과를 종합적, 체계적으로 평가하는 방안을 제시하였다. 기존 감리보고서 위주보다는, 감리 산출물과 행위를 기준에 기반을 두어 평가하였다. 감리행위도 하나의 프로젝트이므로 중요한 성공요인을 평가기준으로 하였고, 감리 산출물도 하나의 프로덕트이므로 프로덕트 평가 프레임워크를 명가기준으로 하였다 따라서 18개 행위, 산출물 명가항목을 도출하여 각각 5단계 배분의 가중치를 적용하는 방안을 제시하였다 각 평가항목에 대하여는 세분화된 평가요소를 도출하여 어떻게, 무엇을 평가한다는 것을 명확히 하였다. 이러한 평가기준에 따른 방안은 감리결과에 대한 신뢰성, 정당성을 높이며. 이는 감리에 대한 정확성, 객관성이 보편적으로 인식되어 그 효과성이 더욱 높아진다.

There are various types of disasters now, and accordingly it is practically difficult to manage all types of disasters effectively. If we are able to reconstruct the disaster event and investigate the cause, it may be possible to prepare the recurrence of similar patterns of disasters. The vehicle-based system equipped with state-of-the-art sensors has been proposed in order to reconstruct the disaster site as much as possible and help the disaster investigator to analyze the cause of the disaster by providing high-quality information. However, the data quality obtained from the sensors can be lowered due to unpredictable circumstances of disaster site. In this aspect it is essential to provide practical procedures that assess and analyze the performance of the equipment on site. In this paper, we selected critical elements of performance that can evaluate the vehicle-based image acquisition system, since it is the most critical piece of information in the disaster sites. The quality of the images obtained from vehicle-based image system was analyzed and verified on the test site. From the results of spatial resolution based on GRD(Ground Resolved Distance), we were able to identify maximum 5mm of spatial resolution at a distance of 70m distance. The result of field test is expected to be used for data acquisition plan in future disaster situations.

For efficient and effective university-industry linked training programs, it is critical to design customized educational systems including various curriculums for specific needs from industries. To do that, we need to understand that the quality of collaboration between large companies and their vendors. Therefore, in this study, we provided SCQM(Supply Chain Quality Management) and QCI-SCM(Quality Collaboration Index for Supply Chain Management) to evaluate the quality levels of collaboration between large sized companies and their sub-vendors. And we tried to find the critical factors for successful SCQM and global quality management competitiveness.

The scale of game development are rapidly increasing as the blockbuster games which cost $7\~20$ billion won, often appear on the markets. The game mechanics which is concentrated on technological elements of the game, necessarily requires the management of quality. In this paper, we propose a computer simulator for the quality evaluation of game mechanics which can analyze the quality accurately and economically in the design phase. The proposed simulator provides Petri net[7,8] and Smalltalk[9] for convenient modeling. The simulator gives the realistic evaluation like play test because it uses the realistic data of gameplay environment such as player action-pattern, game world map, and item DB but the previous evaluation methods can not consider the realistic gameplay environment and can only cover a limited scope of evaluation. To prove good performance of the proposed simulator, we have 80 simulations for the quality evaluation of the game mechanics of Dungeon & Dragon[13,14] in a given world map. The simulation results show that the proposed simulator can evaluate the faultlessness, optimization, and play balance of the game mechanics and gives better good performance than other evaluation methods.

This study conducted empirical analysis through user experience and questionnaire to find out whether the technical and contextual elements of the 'COVID-19 SABER' VR game produced and developed through initial research affect the improvement of the user's visual immersion. As a result first, the hypotheses regarding the resolution, viewing angle, effect, and design quality of the technical elements were accepted, but the hypotheses regarding the frame rate and the brightness of the lighting were rejected. Next, as for the hypothesis of the contextual elements, the hypothesis about background, directing, color and texture, interest and fun was adopted, and the hypothesis about storytelling was rejected. In summary, it was concluded that in order to increase the visual immersion of VR games, technical elements resolution, viewing angle, effect, design quality, contextual elements background, directing, color and texture, interest and fun must be designed and produced. The results of this study are expected to serve as basic data for the production and development of VR games that can induce and improve user's visual immersion in the future.
