  • 대부분의 빈발 패턴은 패턴이 트랜잭션 데이터베이스에 나타나는 support를 패턴 interestingness의 핵심 척도로 다루어 왔으나 패턴의 횟수는 패턴의 completeness가 가지는 정보를 최대치로 가정하고 있다. 그러나 실제적으로는 임의의 패턴 X의 completeness는 트랜잭션에서 서로 다르게 나타나기 마련이다. 따라서 패턴이 가지는 정보의 손실을 줄이기 위해서는 가중치에 의한 support와 completeness에 의한 유용한 패턴 마이닝을 고려하여야 한다. 즉, 높은 completeness율을 갖는 패턴은 더 높은 recall로 이어질 수 있고 높은 빈도수를 갖는 패턴은 보다 높은 정밀도로 이어진다. 본 논문에서는 동적인 항목들의 가중치에 따른 적응된 support와 completeness를 고려하는 WSCFPM 패턴 마이닝 알고리즘을 제안한다. 제안한 방법은 모노톤 또는 반 모노톤 속성이 가중치에 의한 support와 completeness에 영향을 미치지 않기 때문에 탐색과정을 줄일 수 있다. 실험결과를 통하여 제안된 알고리즘이 효과적이며 확장성이 좋은 것임을 보인다.

  • Quantity take-off (QT) is one of the most important tasks for determining the total cost of a construction project, and it requires accuracy and reliability for the result. Accuracy and reliability in BIM-based QT are also required to assure the completeness of the result. However, there has been no basis to measure the completeness of the BIM-based QT result. As BIM is increasingly being adopted in the construction industry with a wide variety of purposes, it becomes more important to have a method to improve the completeness of BIM-based QT and criteria to measure it. This research focuses on the hypothesis that the completeness of BIM-based QT relies on the accuracy and reliability of BIM and the BIM-based QT process. As a basic research to determine the completeness of BIM-based QT, this research analyzes and derives factors that affect the completeness of BIM-based QT.

  • Completeness is an important indicator of data quality in cancer registry programs. This study aimed to estimate the completeness of registered cases in a population based cancer registry program implemented in five provinces of Iran. Capture-recapture methods were used to estimate the number of cases that may have been missed and to estimate rates of completeness for different categories of age, year, and sex. The data used for this study were obtained from three sources: 1) National Pathology Database; 2) National Hospital Discharge Database; and 3) National Death Registry Database. The three sources were linked and duplicates were identified based on first name, last name, father's names, and date of birth, ICD code, and case's residency address using Microsoft Excel. Removing duplicates, the three sources reported a total of 35,643 cases from March 2008 to March 2011. Running many different multivariate models of capture-recapture and controlling for source dependencies revealed an overall under-reporting of 49% in all five registries combined. The estimated completeness differed based on age, sex, and year. The overall completeness was higher for males than females (71.2% for males and 59.9% for females). Younger age had lower rates of completeness compared to older age (38.1% for <40 years, 55.4% for 40-60 years, and 76.7 for >60 years). The results of this study indicated a moderate to severe (depending on the age, sex and year) degree of completeness in the population based cancer registration of Iran.

  • 본 논문에서는 SW감정에서 많이 사용되는 완성도와 기성고의 용어의 정의를 재조명하고, 최근 SW분쟁에서 요구하는 완성도와 기성고의 의미와 산출 방법을 제시한다. 일반적으로 SW감정에서의 완성도는 최종 구축/구현된 SW의 기능상의 완성된 정도를 의미하고 있으며, 기성고는 개발비를 정산하기 위하여 현재까지 완료된 산출물 또는 기능을 기반으로 비용을 산출하는 것을 의미한다. 따라서 완성도는 최종적으로 개발 완료된 제품/산출물의 기능이나 인터페이스를 기준으로 판단하며, 기성고는 SW개발 단계별로 산출물 및 투입된 비용으로 산출된다. 최근에는 SW감정이 복잡해지고 완성도와 기성고에 대한 요구사항이 구체적으로 변화되고 있으므로, 본 논문에서는 각 용어의 의미와 목적을 다시 살펴보고 그 산출 방법을 제시한다.

  • Background : Medical records are used to assess clinical performance of physicians and quality of care. The contents which are written in medical records are considered as the objective evidences to know what the doctors think about the patient's problems. But the problem to use medical records as the assessment tools is the incompleteness of medical recording. The purpose of this study is to know if the completeness of medical recording is correlated to quality of care for inpattients and it can predict physicians's quality of care. Method : 32 clinical physicians reviewed 200 patients' medical records who were selected randomly from the inpatients who were admitted to the university hospital during July, 1995 and June, 1996. The reviewers used the structured evaluation questionnaires which were composed of two part. One part evaluated the completeness of the medical recording and the other evaluating appropriateness of diagnosis and treatment processes. We summated the scores of each items and calculated percentile scores. Results : The mean percentile score of completeness of the medical recording was 67.9% in 1995 and 79.8% in 1996. The mean percentile score of appropriateness was 52.2% in 1995 and 69.5% in 1996. This change between 1995 and 1996 was statistically significant. In non-surgical patients, the percentile scores of the completeness and those of the appropriateness were correlated positively and this correlation was statistically significant(p<0.05). In surgical patients, the positve correlation between the completeness and the appropriateness was also statistically significant(p<0.05). Discussion : In conclusion, the completeness of medical recording is considered as the good predictor of the quality of care for inpatients.

  • Cancer registration is an important component of a comprehensive cancer control program, providing timely data and information for research and administrative use. Capture-recapture methods have been used as tools to investigate completeness of cancer registry data. This study aimed to estimate the completeness of lung cancer cases registered in Ardabil Population Based Cancer Registry (APBCR) with a three-source capture-recapture method. Data for all new cases of lung cancer reported by three sources (pathology reports, death certificates, and medical records) to APBCR for 2006 and 2008 were obtained. Duplicate cases shared among the three sources were identified based on similarity of first name, last name and father's names. A log-linear model was used to estimate number of missed cases and to control for dependency among sources. A total of 218 new cases of lung cancer was reported by three sources after removing duplicates. The estimated completeness calculated by log-linear method was 26.4 for 2006 and 27.1 for 2008. The completeness differed according to gender. In men, the completeness was 26.0% for 2006 and 28.1 for 2008. In women, the completeness was 36.5% for 2006 and 46.9 for 2008. In conclusion, none of the three sources can be considered as a reliable source for accurate cancer incidence estimation.
