  • Six sigma has been the most influential management innovation tool in order to achieve the customer's satisfaction and keep the competition in the age of limitless competition. The success in six sigma is to find the correct CTQ (Critical to Quality). QFD (Quality function deployment) is the efficient too ever created to tie product and service design decisions directly to customer wants and needs. One of the mistakes in QFD is to analyze using an inconsistent HOQ (House of quality) chart. An inconsistent HOQ chart is one in which the information from the correlation matrix is inconsistent with that from the relationship matrix. This study presents the consistency check and inconsistency check in case of failing the consistency check. Also we propose the procedures using the Limiting Probability in correlation matrix and the Median Rank in relationship matrix in order to be consistent in HOQ chart.

  • This study is aimed to validate errors for detected suspicious temperature data using various quality control procedures for 61 weather stations in the Republic of Korea. The quality control algorithms for temperature data consist of four main procedures (high-low extreme check, internal consistency check, temporal outlier check, and spatial outlier check). Errors of detected suspicious temperature data are judged by examining temperature data of nearby stations, surface weather charts, hourly temperature data, daily precipitation, and daily maximum wind direction. The number of detected errors in internal consistency check and spatial outlier check showed 4 days (3 stations) and 7 days (5 stations), respectively. Effective and objective methods for validation errors through this study will help to reduce manpower and time for conduct of quality management for temperature data.

  • In the most of the telecommunication industry, it is necessary to secure consistency to overcome gaps between business logics and information systems logics. We propose a model of provision check in order to secure information consistency of customer information among information systems. First of all, we understand the concept of provision check and design a proposed model for provision check. After an experiment in a business company, we analyze its experimental results and make proposals for effective and efficient provision check in the telecommunication industry.

  • The diagnosis of abnormalities in a nuclear power plant is essential to maintain power plant safety. When an abnormal event occurs, the operator diagnoses the event and selects the appropriate abnormal operating procedures and sub-procedures to implement the necessary measures. To support this, abnormality diagnosis systems using data-driven methods such as artificial neural networks and convolutional neural networks have been developed. However, data-driven models cannot always guarantee an accurate diagnosis because they cannot simulate all possible abnormal events. Therefore, abnormality diagnosis systems should be able to detect their own potential misdiagnosis. This paper proposes a rulebased diagnostic validation algorithm using a previously developed two-stage diagnosis model in abnormal situations. We analyzed the diagnostic results of the sub-procedure stage when the first diagnostic results were inaccurate and derived a rule to filter the inconsistent sub-procedure diagnostic results, which may be inaccurate diagnoses. In a case study, two abnormality diagnosis models were built using gated recurrent units and long short-term memory cells, and consistency checks on the diagnostic results from both models were performed to detect any inconsistencies. Based on this, a re-diagnosis was performed to select the label of the second-best value in the first diagnosis, after which the diagnosis accuracy increased. That is, the model proposed in this study made it possible to detect diagnostic failures by the developed consistency check of the sub-procedure diagnostic results. The consistency check process has the advantage that the operator can review the results and increase the diagnosis success rate by performing additional re-diagnoses. The developed model is expected to have increased applicability as an operator support system in terms of selecting the appropriate AOPs and sub-procedures with re-diagnosis, thereby further increasing abnormal event diagnostic accuracy.

  • 본 논문에서는 최종 변이영상의 정확도를 높이기 위해 영상의 특징점을 이용한 적응적 가변 정합창 방법과 교차 일치성 검사의 신뢰도를 높이는 방법을 제안한다. 제안한 적응적 가변 정합창 방법은 색상정보를 이용하여 영상을 분할하고 분할된 각 영상의 특징점을 찾아 그 특징점들의 유무에 따라 정합창의 크기를 적응적으로 가변시키는 방법이다. 또한 제안한 교차 일치성 검사 방법은 최적의 변이와 차상위 최적의 변이에 대한 비용함수 값들을 비교하여 비용하수 값 자체가 너무 크거나 두 비용함수의 차이가 너무 적은 경우를 찾아내어 처리하는 방법이다. 제안한 두 방법에 대한 Middleburry에서 제공한 네 가지 실험영상을 대상으로 실험한 결과 적응적 가변 정합창 방법은 최대 18.2%의 오차율을 감소시켰다. 또한 제안한 교차 일치성 검사는 최대 7.4%의 신뢰도를 향상시킨 것으로 나타났다.

  • The consistency between a building information model(BIM) and drawings are very important and has a critical impact on the usage of BIM throughout the project life-cycle. The purpose of this study is to develop a checklist for the consistency check between BIM and drawings. In this research, requirements for drawings in the construction documentation phase were analyzed. In generating drawings based on BIM, a checklist can help practitioners confirm what to modify in the BIM model and what to modify in CAD drawings. Finally, it is expected that the work efficiency will be improved by reducing the unnecessary work by distinguishing the elements that can be extracted from the BIM model from the elements that requires additional works when generating BIM-based drawings.

  • 한국어 띄어쓰기 규칙은 경우에 따라 예외 조항이 있어 띄어 쓰거나 붙여 쓰는 것을 모두 허용하는 경우가 있다. 이러한 이중적 규칙에도 불구하고 같은 문서 내의 같은 어절이나 어구들은 일관성 있게 띄어쓰거나 붙여 쓰는 것이 문서 교정상 올바르다. 본 논문에서는 음절 정보 및 형태소 정보를 이용하여 비일관적으로 쓰인 띄어쓰기를 효과적으로 검사하는 방법을 제안하고 실험하여 평가하였다.

  • 클라이언트의 캐쉬된 데이터 관리는 클라이언트 응용의 정확성을 보장하기 위해 필요하다. 캐쉬 일관성 알고리즘은 탐지 기반과 회피 기반의 두 부류가 있다. 탐지 기반의 캐쉬 일관성 방법은 일단 비일관된 데이터의 접근을 허용하고 완료하기 전 캐쉬된 데이터의 유효성을 검사한다. 반면, 회피 기반의 알고리즘 하에서 트랜잭션은 비일관된 데이터를 접근할 기회를 전혀 갖지 않는다. 이 논문에서는 회피 기반의 버전을 이용한 새로운 캐쉬 일관성 알고리즘을 제안한다. 제안하는 방법은 서버와 클라이언트에 이중 버전을 유지하여 단일 버전만 사용한 방법에 비하여 콜백으로 인한 메시지 교환을 제거하고 트랜잭션의 철회율을 감소시킬 수 있다. 또한 갱신 전달을 위하여 무효화와 전파를 혼합하여 사용함으로써 캐쉬 실패를 최소화하였다.

  • In the development of complex software system, it is important to use hierarchical use case model due to the complex scope of development procedure. The use case model is core factor of the OMG (Object Management Group)'s UML (Unified Modeling Language) diagrams. In this paper, we propose a novel method to check syntactic consistency automatically in use case models at the different level of abstraction. This method is a rule-based approach which utilizes actor tree, use case tree and use case description. The proposed method is simulated on ITS (Intelligent Transportation System) architecture for the verification.

  • Purpose: This study is exploratory research to check the survey instrument KDSQ-C used to measure cognition for agreement between the elderly and their caregivers. Methods: Elderly persons from 170 families, who are aged over 65, have never been diagnosed with dementia, and who have caregivers in S City and K City were randomly selected by their nurses. A survey was conducted in the time from September to November, 2009 through personal interviews using a questionnaire. Results: In terms of consistency among items, there was high consistency (0.813) in the responses regarding complex task competence for the statement 'it is hard to reach a destination alone with public transportation'. There was relatively low consistency (0.63) in the responses regard memory for the statement 'they forget an appointment'. When the subject elderly and caregiver live together, as when their children or spouses responded, consistency was greater than when the caregiver lived in a different home. Conclusion: KDSQ-C showed high agreement in measurement between the subject elderly and their caregivers, demonstrating that it can be used as a measurement scale for cognition which can be directly applied to the subject elderly.
