  • This paper will describe integrated system design process and its application. Integrated design process is performed activities concurrently and sequentially for product development. For a group of activities to be truly integrated, the flow of deliverables among them must be well defined, and committed to. For this purpose, the study will suggest procedure that is executed context analysis of standard process, interface definition from activity decomposition, integration of related activities, and definition of concurrency & sequential activities flow, This procedure and method will contribute to minimize time loss that is emerged from activities iteration by not definitely definition of activities interface.

  • Arvesen (1969) has shown a procedure which produces an approximate confidence interval for a variance component in unbalanced one-way classification model. In this paper, his work is extended to the case when the model of interest is unbalanced two-way classification. Following the procedure described in this paper, approximate confidence intervals are computed by a Monte Carlo simulation.

  • Experimenters often want to test whether a specific treatment is really better than the others. In such a problem we derive the likelihood ratio test and compare the result with other multiple comparisons procedures. A nonparametric procedure based on ranks is also considered. Pitman efficiency of the rank-sum procedure relative to the likelihood ratio test is computed.

  • The role of medical service quality to provide patients enhances influence on the hospital performance under being severe competition among the large size hospitals and increasing the right of patients. When a large hospital perceived factors of quality that a customer expects and feels value of care and it invests its resources to improve the factors of quality, it can get successful performances. Therefore, the purpose of the study explores the factors of quality affecting the trust of care and the patient satisfaction, and tests relationship among the trust of care, patient satisfaction and revisit intention. When considering the factors, a large size hospital can increase the trust of care and the patient satisfaction, through this process the hospital can assure patients' revisit and increase its revenue. This study uses interview data on outpatients visiting clinics in about 1000 beds sized training hospital located in Seoul. This study uses casual relationship model for the analysis. This study finds that 1) the trust of care and the procedure of care significantly influence the value of care felt by patients, 2) the trust of care, quality of doctors' care, procedure of care significantly influence the patient satisfaction, 3) the trust of care increases the patient satisfaction, and 4) the value of care and the patient satisfaction increase revisit intention.

  • Advances in computer and sensor technology have made it possible to obtain superlarge manufacturing process data in real time, letting us extract meaningful information from these superlarge data sets. We propose a systematic data analysis procedure which field engineers can apply easily to manufacture quality products. The procedure consists of data cleaning and data analysis stages. Data cleaning stage is to construct a database suitable for statistical analysis from the original superlarge manufacturing process data. In the data analysis stage, we suggest a graphical easy-to-implement approach to extract practical information from the cleaned database. This study will help manufacturing companies to achieve six sigma quality.

  • The Computerized Procedure System (CPS) is one of the primary operating support systems in the digital Main Control Room. The CPS displays procedure on the computer screen in the form of a flow chart, and displays plant operating information along with procedure instructions. It also supports operator decision making by providing a system decision. A procedure flow should be correct and reliable, as an error would lead to operator misjudgment and inadequate control. In this paper we present a modeling for the CPS that enables formal verification based on Petri nets. The proposed State Token Petri Nets (STPN) also support modeling of a procedure flow that has various interruptions by the operator, according to the plant condition. STPN modeling is compared with Coloured Petri net when they are applied to Emergency Operating Computerized Procedure. A converting program for Computerized Procedure (CP) to STPN has been also developed. The formal verification and validation methods of CP with STPN increase the safety of a nuclear power plant and provide digital quality assurance means that are needed when the role and function of the CPS is increasing.

  • 국가통계의 활용도가 높아질수록 통계에 대한 객관적인 품질평가 필요성도 높아지게 된다. 과거에 대표적인 품질평가지표로 간주되어 온 평균제곱오차나 응답률은 유용성에 많은 문제가 있으므로 통계이용자의 다양한 요구사항을 반영할 수 있는 새로운 품질지표 개발의 필요성이 대두되었다. 따라서 본 논문에서는 정부기관에서 작성하고 있는 표본통계조사를 대상으로 통계작성 절차의 흐름을 분석하고 각 절차별 투입자료와 산출결과를 인식함으로써 최종 집계결과의 품질에 영향을 미칠 수 있는 절차별 품질지표를 개발하는 방법이 연구되었다. 또한 발굴된 절차별 품질지표에 다른 통계간 또는 동일 통계간 품질을 비교할 수 있도록 품질지수 산출방법이 논의되었다.

  • Objectives South Korea's air quality standards are insufficient in terms of establishing a procedure for their management. The current system lacks a proper decision-making process and prior evidence is not considered. The purpose of this study is to propose a measure for establishing atmospheric environmental standards in South Korea that will take into consideration the health of its residents. Methods In this paper, the National Ambient Air Quality Standards (NAAQS) of the US was examined in order to suggest ways, which consider health effects, to establish air quality standards in South Korea. Up-to-date research on the health effects of air pollution was then reviewed, and tools were proposed to utilize the key results. This was done in an effort to ensure the reliability of the standards with regard to public health. Results This study showed that scientific research on the health effects of air pollution and the methodology used in the research have contributed significantly to establishing air quality standards. However, as the standards are legally binding, the procedure should take into account the effects on other sectors. Realistically speaking, it is impossible to establish standards that protect an entire population from air pollution. Instead, it is necessary to find a balance between what should be done and what can be done. Conclusions Therefore, establishing air quality standards should be done as part of an evidence-based policy that identifies the health effects of air pollution and takes into consideration political, economic, and social contexts.

  • Multistage screening is a common practice when a component has a critical effect on the function of the assembly. A defect in a component might incur malfunction of an electronic device, resulting in a great amount of loss. Multistage screening, including duplicated screening inspections, may provide a good solution for this problem when inspection errors are present. In the company studied here, the manufacturing process of the multiple layer chip capacitor includes two-stage screening. In the first stage, screening inspection is performed repeatedly until no defects are found in the lot. In the second stage, sampling inspection is performed by a group of experts prior to shipment. In this article, we review the procedure used in the field and suggest a revised model of the multiple screening procedure and solution method for this situation. The usefulness of the proposed model is discussed through a practical example.
