  • 본 연구는 강남일부(강남구, 강동구, 송파구)지역 시설재배지에서 시기별 잔류농약의 오염 실태를 파악하고자 하였다. 각 지역에서 2010년 4월부터 2011년 6월까지 토양시료 60 점을 채취하여 시료 중 농약 잔류량을 다성분 동시 스크리닝 분석법으로 분석하였다 시설재배지 잔류농약 조사결과, endosulfan 0.002-0.999 mg/kg, procymidone 0.002-1.200 mg/kg, diazinon 0.003-0.024 mg/kg, metalaxyl 0.012-0.075 mg/kg로 검출되었다. 시설재배지 토양의 잔류농약 모니터링 결과 검출빈도가 높게 나타난 endosulfan을 대상으로 참나물, 상추에 대하여 흡수 이행 정도를 조사하였다. 강남구 지역의 토양에서 잔류농약을 검사한 결과 endosultan이 0.445 mg/kg로 잔류하였고, 이 토양에서 참나물을 60일 재배 후 잔류농약 검사를 실시한 결과 endosulfan 0.157 mg/kg로 잔류하여 토양 대비 참나물 중 endosulfan 이행률은 35.3%를 보였다. 또한 강동구 지역의 토양에서 잔류농약을 검사한 결과 endosulfan이 0.358 mg/kg로 잔류하였고, 이 토양에서 상추를 60일 재배 후 상추 중 잔류농약 검사를 실시한 결과 endosultan 0.004 mg/kg로 잔류하여 토양 대비 endosulfan 이행률은 1.1%를 보였다.

  • General Administrative Procedures of the Preshipment Inspection 1. Initial notification Preshipment Inspection is initiated by Agency when it receives notice either from the importing country, or the seller, that an export needs to be imspected 1.1 Notice from the importing country 1.2 Notice from the seller 2. Preliminary price verification After receipt of initial notification, Agency undertakes, Where possible, a preliminary price verification, based upon the Inspection Order and other contractual documents received. 3. Customs classification When required by the Government of the importing country. Agency forms an opinion of the Customs Classification Code based upon the Customs Tariff Book and Rules of Classification of the country of importation. The Customs Classification Code determines the tariff rate on the basis of which the importer will be required to pay import duties. 4. Import eligibility 5. Arrangements for physical inspection 5.1 Inspection request from seller 5.2 Place of inspection 5.3 Date of inspection 5.4 Physical inspection procedures 6. Physical inspection results When the physical inspection is completed, the inspector submits his report to the Agency office and the result of inspection will be communicated to the seller and, where applicable, the place of inspection. The result will state: satisfactory or conditional of unsatisfactory. The seller is welcome to present his views in writting to Agency in the event there is any query regarding the issuance of a conditional of unsatisfactory inspection result. 6.1 Satisfactory 6.2 Conditional 6.3 Unsatisfactory 7. Shipment of the goods The seller is advised to check with Agency prior to shipment if the physical inspection result has not been received or there are any doubts concerning whether a Clean Report of Findings will be issued. 8. Final price verification and classification Based on the results of physical inspection and appropriate final documents, Agency finalises the price verification and the Agency opinion of Customs classification code. When the preliminary price verification has not resulted in any unresolved questions and the inspection result and other documents received are consistent with the preliminary documentation, Agency will not normally require any additional information. The main exception would be if the terms of sale require reference to prices at the date of shipment. 9. The Report of Findings 9.1 Types of Reports of Findings - Clean Reports of Findings(CRF) The Agency will issue a Clean Reports of Findings(CRF), or equivalent document, normally within two working days after receipt of the necessary correct final documents and a satisfactory result in all aspects of the inspection. - Discrepancy Report.

  • The inspection of bridge condition is of extreme importance. Current inspection codes for bridge inspection are vague and uncertain. So, the results are highly subjective and different from person to person and even day to day for a given person. To circumvent possible inconsistencies in inspection and rating of bridge components, the revised inspection guidelines have been proposed.

  • A methodology for determining optimal sampling plans for Bayesian multiattribute curtailed inspection models is proposed, whereby sampling inspection is terminated as soon as the disposition of the inspection lot is determined. An iterative solution procedure is developed for obtaining optimal multiattribute acceptance sampling plans under cuntailed sampling inspection.

  • 직물의 결점은 원단손실을 가중시키기 때문에, 검단공정에서 결점부위를 제거한다. 실제공장에서 이뤄지는 검단공정은 육안판정방식과 전자동 방식 중 하나를 채택하는데, 두 방식 나름대로 장단점이 있다. 본 연구에서는 육안판정과 전자동 방식의 장점만을 모아 검출은 사람이 하지만, 결점위치 정보 제공 및 결점정보 기록을 컴퓨터가 하도록 반자동 검단기를 개발하였다. 본 연구에서 개발한 레이저 그리드는 결점의 위치를 검단자가 쉽게 파악하도록 돕는 역할을 하며, 야드미터는 자동으로 결점의 위치를 측정하는 역할을 한다. 컴퓨터는 야드미터로 측정된 직물의 길이와 사람이 검출한 결점의 위치정보를 받아들여 저장하고 직물의 결점정보를 한눈에 보여주는 역할을 한다. 실제 사용되는 직물을 대상으로 특정 패턴으로 재단했을 때의 손실률을 계산하여 개발된 시스템의 성능을 객관적으로 평가하였다.

  • 컴퓨터용 Lead Screw는 검사방식이 수동검사로 이루어져 작업자의 주관적 판단으로 인한 미검출과 과검출이 발생하고, 생산성이 저하되는 단점이 있다. 따라서 본 연구에서는 이러한 단점을 보완하고자 Lead Screw 자동검사 시스템을 개발했다. 검사시스템은 Lead Screw 자동공급 및 이송을 위한 공급 이송 장치와, 표면검사를 위한 $360^{\circ}$ 회전장치, 치수검사를 위한 머신비젼 부분으로 구성된다. Lead Screw 자동검사 시스템으로 표면과 치수 측정결과, 오검률 및 미검률이 수동검사 결과보다 우수함을 보였다.

  • This work present a new method of sealing inspection system for vehicle in which foam rubber materials are used for sealing the vehicle parts. This system is composed from a devices comprising non-contact and real-time scanning on visual inspection in machine parts. We have been investigated qualitative factors that influenced on sealing system of vehicle structure which flexibly attenuated vibration and plenty of foam rubber materials having elastic property. However, there are different factors which still depended on outdated technique (personnel subjective judgment) in the performance inspection of rubber parts, specially for cross section inspection. Through a newly developed inspection system which recently applied for the production line, we successfully achieved more effective results of matching rate by about 80 % in the sealing performance inspection with 0.7% to 1.4% in the repeated errors. These are resulted from non-contacted response by CCD camera and vision program using geometry matching method. We expect that this system may be widely applied in the strict inspection parts of more diverse cross-section in future.

  • The periodic inspection of piping and pressure vessels welds in nuclear power plant has to provide reliable result related to weld flaws, such as location, maximum amplitude response, ultrasonic length, height and finally the nature or flaw pattern. The founded flaw in ultrasonic inspection is accepted or rejected based on these data. Specially, the amplitude of flaw response is used as basic parameter for flaw sizing and it may cause some deviation in length sizing result. Currently the ultrasonic inspections in nuclear power plant components are performed by specific inspection procedure which describing inspection technique include inspection system, calibration methodology and flaw characterizing. To perform ultrasonic inspection during in-service inspection, reference gain should be established before starting ultrasonic inspection by the requirement of ASME code. This reference gain used as basic criteria to evaluate flaw sizing. Sometimes, a little difference in establishing reference gain between calibration and field condition can lead to deviation in flaw sizing. Due to this difference, the inspection result may cause flaw sizing error. Therefore, the objective of this study is to compare and evaluate the ultrasonic amplitude difference between air filled and water filled pipe in nuclear power plant. Additionally, the accuracy of flaw sizing is estimated by comparing both conditions.
