The research interprets the principles of sampling error design for quality statistics models such as hypothesis test, interval estimation, control charts and acceptance sampling. Introducing the proper discussions of the design of significance level according to the use of hypothesis test, then it presents two methods to interpret significance by Neyman-Pearson and Fisher. Second point of the study proposes the design of confidence level for interval estimation by Bayesian confidence set, frequentist confidential set and fiducial interval. Third, the content also indicates the design of type I error and type II error considering both productivity and customer claim for control chart. Finally, the study reflects the design of producer's risk with operating charistictics curve, screening and switch rules for the purpose of purchasing and subcontraction.

Even though ruin probability is a fundamental value to determine the insurance premium and policy, the complexity involved in computing its exact value forced us resort to an approximate method. In this paper, we first present an exact method to compute ruin probability under the assumption that the claim size has a GPH distribution, Then, for the arbitrary claim size distribution, we provide a method computing ruin probability quite accurately by approximating the distribution as a GPH. The validity of the proposed method demonstrated by a numerical example. The GPH approach seems to be valid for heavy-tailed claims as well as usual light-tailed claims.

An early detection system for warranty issues periodically collects customers' claim data and automatically reports alarms about emerging issues based on statistical algorithms. It helps companies to reduce an issue definition time and save the handling cost of warranty claims. This paper provides an evaluation framework to validate the economic effect of an early detection system project. For this purpose, we present economical index of a project with explicit formulas such as ROI(return on investment), PP(payback period), NPV(net present value), PI(profitability index) and IRR(internal rate of return) and analyze the sensitivities of the index according to the variation of project input parameters. The proposed analysis framework is expected to be used for evaluating economic values of various system integration projects.

Six sigma, contrary to TQM, offers the concrete process for accomplishing the management innovation. Nowadays it has become as a standard means. Many companies claim to stand for durable management and would like to get customers' satisfaction and more profit with total six sigma activities. Under the present conditions we propose how to maximize efficiency with six sigma application on transportation management that is an issue among many companies.

Background: This study examined what factors affected a complete examination of infant health checkup. Methods: We used Korean national health insurance claim data of 2,936,650 infants, taking examination in 2012. These claim data included enrollment status of householders and records of infant health checkup from 2008 to 2013. Results: Our results shows that for infant characteristics, the likelihood of complete examination of infant health checkup is significantly lower in female, older aged, and handicapped ones. For householder characteristics, the likelihood of complete examination of infant health checkup is also significantly lower in female, older group and self-employed ones. For household characteristics, the likelihood of complete examination is also significantly lower in single-parent families, multi-cultural families, parent with unexperienced health checkup and lower monthly premiums. Conclusion: It is necessary to support an additional use-guide and follow-up management services to improve incomplete examination of infant health checkup.

Construction Projects have many participants by characteristic, scale and contract. Those also have complicated communication structure. So, claim and dispute occur continuously for conflicting communication. In many claim and dispute cases, it usually occurs between builder and owner. Unfair practices by owners position cause main claim and dispute. This study analyses judgment type, cause and compensation ratio in korean commercial arbitration case and provides the dispute information for builder that has weak position by contract. It draws analysis information for managing and controlling dispute that order type, judgement type, cause and failure case. Using these analysis information, it hopes to help inducement of dispute agreement and save time and economic damage for builder during construction. It also hopes to rise construction completeness by providing dispute management information.

A new classification framework called 'support feature machine' was introduced in [2] for analyzing medical data. Contrary to authors' claim, however, the proposed method is not designed to guarantee minimizing the use of the spatial feature variables. This paper mathematically remedies this drawback and provides comments on models from [2].

Claims in the construction industry can have a serious impact on the profitability of the project or can even result in project failure if it fails to take appropriate prevention. In order to properly prevent and respond to the potential claims and legal disputes throughout the project execution, it is necessary to continuously accumulate informations and clearly define the roles and responsibilities of the important activities systematically. Based on these needs, this study develops and verifies the project information management system(PMIS) that can prevent and respond possible claims for construction projects. Developed system includes such management modules as schedule, cost, PM/CM, design, collaboration, and claims. The system was validated by adopting it to the practical projects. The results showed that information systems tailored to the construction claim need to elevate users' familiarity to be more useful. Besides, the system can be more functional when used by both owners and contractors.

All industrial Products of today are various demand of customers and are switchovered the manufacturing system of a small quantity batch production. Its life cycle was very shortened. An enterprise is improved to satisfaction with external customers and internal customers of infinity competition time. They can exist on achieving customer satisfaction management. In this paper, a new implementation of service information system (SIS) with real time using RFID and X-Internet in Ubiquitous environments is proposed. The proposed SIS system has Web architecture based on XML and has a new X-Internet environment overcoming limitation of Client/server architecture. The service information system analyze its material data and suppress the same CLAIM creation. The implementation method of real time SIS system using RFID and X-Internet is proposed for contribution of business market reducing F-Cost.
