비즈니스 프로세스란 기업의 모든 고객에게 적절한 서비스를 제공하기 위해 순차적 또는 동시적으로 발생할 수 있는 모든 연관된 업무의 집합을 의미한다. 이러한 비즈니스 프로세스는 프로세스 설계 작업을 통하여 시스템 차원에서 관리함으로써 프로세스의 생산성 및 효율성 등을 확대하게 된다. 하지만 프로세스 설계 작업은 주로 사람에 의해 수행되기 때문에 예상하지 못한 오류들이 발생할 수 있게 된다. 이러한 설계 오류들은 기업이 원하는 과정으로 프로세스가 진행하지 않을 수 있으며, 이는 기업의 막대한 인적 손실 및 비용 손실을 초래하게 된다. 그러므로 비즈니스 프로세스 설계 단계에서 오류가 없도록 설계 하거나 또는 미리 정의된 오류 유형들을 설계 도구를 통하여 검출 할 수 있는 작업이 필요하다. 본 논문에서는 비즈니스 프로세스 설계 단계에서의 오류 검출 작업에 활용될 수 있도록 유형 별로 설계 오류들을 분석 하고 정의하였다.

화학제품 제조업에서 발생하는 사고는 인체에 치명적인 영향을 줄 수 있기 때문에 다른 어떤 작업장에서보다 높은 안전성과 신뢰도가 요구된다. 이전의 화학 제품 제조업에서 발생한 사고의 분석으로부터 작업자들의 인적오류가 사고의 주요 원인이라는 것이 입증되어 왔다.(중략)

The aim of study is to present a better teaching strategy to reduce writing errors of Chinese learners of Korean language after finding out what reasons of errors were after analyzing of their writing errors in Korean language. Analyzed contents were writhing in Korean language of 'how I think Korean', 'about Chinese and Korean culture', 'friends' and analyzed what errors were occurred. The vocabulary errors frequencies were counted by the criteria which was set by a researcher. The results were as follows. The frequency of substitute error was the most and were followed by spelling error, wrong type error, omission error and adding error. It is suggested when we teach Korean Language to Chinese learners and develop text for them, the vocabularies should be presented with examples of how to be used in context instead of presenting only vocabulary on the text. It would be a better way to reduce writing errors of Chinese learners of Korean language.

Digital Radiography is a big part of diagnostic radiology. Because uncorrected digital radiography image supported false effect of Patient's health care. We must be manage the correct digital radiography image. Thus, the artifact images can have effect to make a wrong diagnosis. We report types of occurrence by analyzing the artifacts that occurs in digital radiography system. We had collected the artifacts occurred in digital radiography system of general hospital from 2007 to 2014. The collected data had analyzed and then had categorize as the occurred causes. The artifacts could be categorized by hardware artifacts, software artifacts, operating errors, system artifacts, and others. Hardware artifact from a Ghost artifact that is caused by lag effect occurred most frequently. The others cases are the artifacts caused by RF noise and foreign body in equipments. Software artifacts are many different types of reasons. The uncorrected processing artifacts and the image processing error artifacts occurred most frequently. Exposure data recognize (EDR) error artifacts, the processing error of commissural line, and etc., the software artifacts were caused by various reasons. Operating artifacts were caused when the user didn't have the full understanding of the digital medical image system. System artifacts had appeared the error due to DICOM header information and the compression algorithm. The obvious artifacts should be re-examined, and it could result in increasing the exposure dose of the patient. The unclear artifact leads to a wrong diagnosis and added examination. The ability to correctly determine artifact are required. We have to reduce the artifact occurrences by understanding its characteristic and providing sustainable education as well as the maintenance of the equipments.

Recently a student's mathematical thinking and problem-solving skills are emphasized. Nevertheless, the students solved the problem associated with a given type of problem solving using mechanical algorithms. With this algorithm, It's hard to achieve the goal that are recently emphasized. Furthermore It may be formed error or misconception. However, consistent errors have positive aspects to identify of the current cognitive state of the learner and to provide information about the cause of the error. Thus, this study tried to analyze the error happening in the process of solving gearwheel-involved problem and to propose the correct teaching method. The result of student's error analysis, the student tends to solve the gear-wheel problem with proportional expression only. And the student did not check for the proportional expression whether they are right or wrong. This may be occurred by textbook and curriculum which suggests only best possible conditioned problems. This paper close with implications on the discussion and revision of the concepts presented in the curriculum and sequence related to the gearwheel-involved problem as well as methodological suggested of textbook.

Since the late 1950s, concerted efforts to reduce the accident rate in aviation have yielded unprecedented levels of safety. Although, the overall accident rate has declined considerably over the years, unfortunately reductions in human error-related accidents in aviation have failed to keep pace with the reduction of accidents due to environmental and mechanical factors. Today, a very large percentage of all aviation are attributable, directly or indirectly, to some form of human error. As a result of many study, a range of prevention of human error have been developed. but each of kind is lack of a precision, effectiveness and seem to be considered for aspect of deficiency as an systematic accessibility. So, we're going to analysis the most effective and systematic prevention of human error and study on consolidating method for human error and aviation safety. In this study, several alternatives for the prevention of human errors a priority to understand and solve problems by identifying the implications for human error to be presented.

The data are often missed and many errors of the data are generated in the input process for the post evaluation system on the construction projects, and the reliability of the data falls down much. Accordingly, the detailed analysis about missing and error of data was conducted to ensure reliability of the analysis results about post evaluation on the construction projects. As results in this study, a lot of input data were missed at the initial construction phase, and the data errors were found in the inaccuracy of reference reports, the lack of understanding about input data, and the failure of KRW unit.

When structural analysis modelling methods of practical fields are investigated, a slab is generally modeled by a finite element mesh using plate elements and a shear wall is modeled using a shell element or wall element for 3-D structural analysis. The point worthy of notice in this practice is that a shear wall is modelled using only one wall or shell element divided by floors and column lines to produce structural models. The modeling method like this can cause analysis errors according to the type of computer programs in use, and these errors reduce the reliability of the analysis results. Therefore, to secure the reliability of structural analysis, studies of the causes of errors and finding reasonable modeling methods are necessary. In this study, the causes of analysis errors according to the modelling methods of a shear wall, which are used in practical fields, were investigated and some considering matters for modelling a shear wall are presented to reduce the analysis errors on these analysis results.

한국어 문서에는 여러 어절을 검증해야만 처리할 수 있는 의미 오류와 문체 오류가 있다. 다수 어절 사이에 있는 오류는 부분 문장 분석을 한다. 논문에서는 의미 오류와 문체 오류를 처리할 때 어휘적 중의성 때문에 생기는 문제점을 제시하고 해결방법을 제안한다. 어휘적 중의성이란 한 단어가 두 가지 이상의 형태소 정보를 가짐을 뜻한다. 철자검사기와는 달리 문법 검사기에서는 어휘적 중의성을 제거하지 않으면 여러 가지 검사 오류가 발생한다. 이 논문에서는 의미, 문체 시스템에서 어휘적 중의성 때문에 검사 오류가 발생할 수 있는 과정을 크게 세 단계로 분류하였다. 연어 오류가 발생할 수 있는 검사단어가 어휘적 중의성을 가지면 표제어가 다른 규칙이 여러 개 존재한다. 이 때 규칙 선택 문제가 생긴다. 중의성 문제는 부분 문장분석 과정에서도 지배소와 의존소 사이의 의존관계를 정확하게 설정하기 어렵게 한다. 본 논문에서는 각 단계에서 발생한 문제를 최소화하여 문법 검사기의 성능을 향상시킨다.
