  • Monitoring of pesticide residues were conducted at three sites in the Southern Area of Seoul, Korea (Gang-nam, Gang-dong and Song-pa). We measured pesticide residues within soil samples using multi-pesticide residues analysis. Samples were collected at the three sites with 60 sampling spots. The amount of pesticide residues in the soil samples were as follows [(minimum-maximum), mg/kg] endosulfan 0.002-0.999, procymidone 0.002-1.200, diazinon 0.003-0.024, metalaxyl 0.012-0.075. In soil treated with 0.445 mg/kg of endosulfan, the pesticide absorbed by chamnamul, was 0.157 mg/kg (Absorption rate : 35.3%). However, in soil treated with 0.358 mg/kg of endosulfan, the pesticide absorbed by lettuce, was 0.004 mg/kg (Absorption rate : 1.1%).

  • 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.

  • The inspection processing is for reducing loss which occurs fault because of fabric appearance. Up to now inspection machine which is used from inspection process is classified with the macrography inspection machine and the full automatic inspection machine. The macrography inspection machine is low price and efficient equipment but does not record information of fault. On the other side, the automatic inspection machine is high price, also the detection rate of one changes with effect of environment variable but able to record information of fault. It developed semi-automatic cloth inspection machine with the weak point of the macrography inspection machine and the automatic inspection machine was complemented. And when it uses information which was collected by semi-automatic cloth inspection machine, the loss rate of original fabric is able to calculate. So sewing factories will be able to predict fabric consuming quantity.

  • In manual inspection of Lead Screw of computers many workers are needed to inspect samples, and its main disadvantage is that such types of inspection system not only gives low production, but also gives low perfection. Besides, in manual inspection system, the inspection cost of samples is higher than that of the automatic inspection system. Therefore, in this study to compensate these shortcomings, an automatic inspection system is developed. For the inspection of the surfaces and different dimensional parameters of computer Lead screw, a $360^{\circ}$ rotating machine vision system is developed. From the detailed analysis of the inspection results using the present developed inspection system, it is observed that the developed Lead Screw automatic inspection system is superior to those of manually inspection system.

  • 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.
