For situations where there are several markets with different price/cost structures, economic complete inspection plans are developed for determining the market to ship the product to. Two complete inspection plans are considered; the plan based on the performance variable of interest, and the plan based on a variable which is correlated with the performance variable. Profit models are constructed which involve selling price, cost incurred by imperfect quality, and quality inspection cost. Methods of finding the optimal complete inspection plans are presented and a numerical example is given.

This paper presents a model that considers combinations of rework, repair, replacement and scrapping. Policy-Iteration method of inspection is proposed for a serial manufacturing system whose repair cost, scrap cost and inspection cost. when it fails, can be formulated by Markovian approach. Policy-Iteration stops when new inspection policy is the same as previous inspection policy. A numerial example is presented.

This study is concerned with the development of the economic sampling inspection plan when it is possible to carry out a nondestructive screening inspection for the rejected lots by substitutive characteristics closely related to the original quality characteristic. It is assumed that the probabilities of those errors depend linearly on the fraction defective of the process sampling inspection policy for isolated lot is studied where the probability of accepting the lot with bad quality from the results of sampling inspection is restricted to be small.

The inspection policy and inspection error are very critical factors which influence the outgoing quality. In other words, such factors influence the acceptance rate of the incoming matarials. Hence, the outgoing lot size is varied. This paper presents a method to compute the break-even point(pb1, pb2) under these two factors, which canbe used to determine the economic acceptance inspection type.

Objectives Eyes, one of visual inspection regions, present important clues to pathological patterns including deficiency and excess patterns to the clinicians. The purpose of this study was to develop Eyes Inspection Questionnaire (EIQ) and to examine which items among the EIQ were more predictive of clinicians' determination for the deficiency and excess patterns. Methods Nine questionnaire items for Visual Inspection of Eyes were extracted through the literature review. These items were presented to the 4 Korean medical doctors who are specialized in visual inspection to conduct the Delphi method. The Korean medical doctors were asked to rate the importance of each items for the corresponding Visual Inspection of Eyes, using a Likert 5-point scale(the 3 points of importance as a cut-off point). Then, out of 75 photographs submitted to the Society of HyungSang Medicine in 2009, 30 portrait pictures were selected as samples. The samples were copied to make 60 sample pictures, and then randomly assigned to 4 clinicians. The 4 clinicians evaluated the 60 samples for excess and deficiency of the eyes and were asked to check the 6 questionnaire items. The results were recorded as 5-points-scale, and their average and standard deviations were calculated. Intra- class reliability test and multi regression test were performed using SPSS 13. Results Intra-class correlation coefficient (ICC) was between 0.750 to 0.841 (P<0.05). Indices for visual inspection of the eyes were: endowment of the bone structure around the eyes; brightness of the eyes; upward deviation of the eyes; eye shapes; and definition of iris. 76.92% of deficiency symptom patterns and 86.42% of the excess symptom patterns matched the patterns predicted by the visual inspection of the eyes, according to the frequency analysis. According to the multiple regression analysis, were significantly related to the excessive symptoms, and to the deficiency symptoms. Conclusion This study is the first attempt of development for checklist of excess and deficiency of Visual Inspection of Eyes and quantitative measurement of excess and deficiency using the Visual Inspection of Eyes by the visual inspection experts. Still, additional studies are needed regarding the relationship visual inspection methods have with existing standards of diagnosis.

본 연구는 경기도에서 유통 중인 수입과실류에 대한 잔류농약 분석을 수행하였다. 총 22품목 124건의 시료를 구입하여 GC/NPD-ECD, TOF/MS, UPLC/PDA 및 HPLC/FLD, LC/MS/MS를 이용하여 218종 잔류농약을 동시 다성분 분석법으로 분석한 결과 18건의 과실에서 잔류농약이 0.003~0.3 mg/kg 범위로 검출되었으나 기준초과 시료는 없었다. 과실의 부위별 특성에 따른 잔류농약정도를 알아보기 위해 농약이 검출된 과실류 중 14건에 대하여 분리 실험을 실시하였으며, 그 결과 과피 14건에서 0.03~1.5 mg/kg, 과육의 경우 2건에서 검출한계 미만으로 나타났다. 실험결과 모두 잔류농약허용기준 이내에서 검출되어 정상적인 방법으로 섭취할 경우 위해도는 매우 낮은 수준이었다. 그러나 미량이라도 장기간 섭취시 인체에 유해할 수 있으며, 검출빈도가 높은 성분들이 검출되므로 수입과실에 대한 지속적이고 체계적인 모니터링이 필요하겠다.

본 연구에서는 2012년 1월부터 8월까지 농산물 중 엽채류에 대하여 GC-ECD 및 GC-MSD를 이용하여 uniconazole의 잔류실태조사를 실시하였다. 겨자채에 표준용액을 0.05, 0.5 mg/kg 농도로 하여 회수율을 측정한 결과 98.9%에서 109.4%까지 양호한 결과를 나타내었다. 2012년 1월부터 8월까지 서울지역에 유통되고 있는 농산물 중 엽채류 3,632건에 대하여 모니터링을 실시한 결과 14건에서 uniconazole이 검출되었다. Uniconazole의 검출양은 0.098 mg/kg에서 2.2 mg/kg로 나타났다. 본 연구를 통하여 동시분석법으로 보다 효율적인 검사가 가능할 것으로 기대된다.
