  • This study describes the development of a web-based system that collects all data generated in the research conducted to set pre-harvest residue limits (PHRLs) for agricultural product safety control. These data, including concentrations of pesticide residues, limit of detection, limit of quantitation, recoveries, weather charts, and growth rates, are incorporated into a database, a regression analysis of the data is performed using statistical techniques, and the PHRL for an agricultural product is automatically computed. The development and establishment of this system increased the efficiency and improved the reliability of the research in this area by standardizing the data and maintaining its accuracy without temporal or spatial limitations. The system permits automatic computation of the PHRL and a quick review of the goodness of fit of the regression model. By building and analyzing a database, it also allows data accumulated over the last 10 years to be utilized.

  • Purpose: This study explored factors affecting the purchase of fair trade hand-made products. We focused on the difference between the mediating effect of purchase intention and purchase purpose, and verified the additional effectiveness of premium prices. Research design, data and methodology: The data was collected through an online survey. The reliability and validity of each variable used in the questionnaire were verified. Then, each hypothesis was analyzed through multiple regression analysis. Results: First, individual social responsibility and purchasing experience of general fair trade products have a definitive effect on the intention of purchasing fair trade hand-made products. Second, the willingness to pay premium prices varies depending on whether it is an individual's consumption or consumption for others. Third, the higher the individual's social responsibility and experience in purchasing fair trade products, the more willing he is to pay premium prices. Fourth, the purchase intention of fair trade hand-made products is to have the effect of partial mediation. Fifth, when choosing a gift for an adult, it was determined that the consumer was willing to pay premium prices the highest amount. Conclusions: In terms of factors affecting the purchase of fair trade hand-made products at premium prices, it was confirmed that individuals' social responsibilities and purchases of fair trade general products had an impact.

  • Reliability test is focusing to detect the unexpected reliability failure and solve them for the high quality of products. The test data should be used to assess and project the current level of interesting product reliability and so it is very important to have the accurately assessing methodology with test data. There are two type of trend for test data as constant and changing one during testing and this paper shows the difference in the assessing results of these two cases. There is less information how to define the existence of reliability growth rate changing and calculate the parameters of the reliability growth models to make an accurate assessment with such condition, so i established the process and mathematical model to calculate the parameters at such condition to make reliability growth curve with high Goodness of Fit. I validated the new method with the data made from Monte Carlo Simulation and case from Demko (1993). Even the assessed result with the new methodology may be different with the case by case because of very diversity in test condition and testing product quality, but the process and method founded in this research can be applied to any case using Duane and AMSAA model for their test data assessment. I also present the evaluation method to see the effectiveness with new one which is a conventional knowledge and not popular to use, so it is possible to compare the results with the newly presented and conventional method for better business decision.

  • The reliability guarantee insurance policy for parts and materials was introduced to the market in 2003. This policy indemnifies manufactures of products for the repair/failure costs, recall expenses of products and business interruption losses found to be defective by users or demand companies during the terms of guarantee and after the user acquired physical possession of the product. In this paper, owing to the nature of the policy, we propose a new rate-making system considering the type of product and industry, quality control circumstances, record of guarantee performance, and exposure.

  • 상용품목을 군용환경에서 적용하면 저비용, 빠른 조달시간, 기술적 발전 등 여러 가지 이점이 있다. 반면에 상용 제품, 표준, 관행 등이 군용 요구조건에 미달됨으로 인하여 신뢰도 및 병참 상의 문제가 발생할 수도 있다. 또한 상용 공급자들은 군용 병참을 지원하는데 필요한 기술적 자료를 제공한 경험이 거의 없을 수도 있다. 보다 많은 회사들이 제품 관련 데이터 수집 시스템을 구축하고 있어 상당한 분량의 사용현장 보증 데이터가 수집되었다. 사용현장 데이터는 전형적으로 주기별 판매량과 클레임 건수로 구성된다. 본 연구에서는 군용환경에서 작동하는 군용설비, 군용환경에서 작동하는 상용설비, 상용환경에서 작동하는 상용설비 등 세 가지 유형의 데이터를 고려하였다. 최대우도 기준 및 최소제곱 기준에 기초한 제품 신뢰도 추정 방법을 제안하고, 각 유형의 데이터에 대한 추정 모형을 구축하고 상용환경에서 군용환경으로 전환하는 신뢰도 변환방법을 제안하였다. 사례연구를 통하여 제안된 방법의 적용 가능성을 검증하였다.

  • The objective of this study is to propose a necessity of alternative certification for low-pesticide agricultural products (LPAP). For this, we conduct a survey consumer and distributor. Most of consumer does not aware an abolition of LPAP. After abolition, they will purchase pesticide-free, organic, conventional, GAP certificated in order. Both consumer and distributor need an alternative certification of LPAP and have willingness-to-purchase. However, it is necessary to make up for the reliability and objectivity on the alternative and to manage a poor certification. The results of this study is meaningful to distribution and consumption of environment-friendly agricultural products.

  • Determination of sex origin of cattle meat by fast and reliable molecular methods is an important measure to ensure correct allocation of export refunds particularly in European countries and also female cattle (cow) slaughter is legally banned in India because of religious beliefs. Based on the DEAD box protein gene located on the X and Y chromosomes, 2 pair of primers were designed and the system of PCR was optimized. Upon PCR amplification, male tissue showed 2 bands, while female tissue resulted in only one band. The accuracy and specificity of the primers was assessed using DNA template extracted from cattle meat of known sex. The protocol was subjected to a blind test and showed 100% concordance, proving its accuracy and reliability.
