In this study, we evaluated the efficiency of chemical marking of black rockfish scales by immersion in oxytetracycline hydrochloride (OTC, 500 ppm), alizarin red S (AR, 250 ppm) and calcein (CARL, 250 ppm) diluted rearing water. Immersion treatment of chemicals had no effects on both mortality and growth of black rockfish. Marking sucess was 100% in all treatment durations (24, 48 and 72 hours) with three chemicals and marking quality was higher in 48 and 72 hours than 24 hours treatment. Marking retention rates at 24 weeks after treatment were 100% in OTC and CAL treated group, but marking quality was higher in CAL treated group (brilliant 92%, bright 8% and dim 0%) than in OTC treated group (brilliant 4%, bright 70% and dim 26%). AR treated group had lower marking retention rates and marking quality than OTC and CAL treated group. As a results, immersion treatment with OTC and CAL was effective in marking scales of black rockfish and practical in releasing program and other studies requires same rearing environment.

This study intended to compare and analyze marking efficiencies of tailored jacket based on different cloth and production conditions, 'the width of cloth', 'the number of marking pieces' and 'the direction for marking deployment'. The results were as follows. For the two pieces of markers, the efficiency of the cloth width of 110cm was higher than that of 150cm. As the number of markers increased, the efficiency of cloth width of 150cm was higher than that of 110cm. In the case of one-directional deployment, the results obtained was that the efficiency of two markers was higher than that of three markers, while, in the case of bi-directional deployment, the efficiency of three markers was higher than that of two markers. In the case of one-directional deployment for each size, the marking efficiencies were higher in two markers at the cloth width of 110 cm and higher in three markers at the cloth width of 150 cm. Then, in marking efficiencies according to the direction for marking deployment, bi-direction marker was the most efficient marker, followed by one-direction for each size marker and one-direction marker.

In this paper, we have proposed a novel re-marking strategy at tbe ingressive edge router to improve TCP fairness of DiffServ Assured Services. Our re-marking strategy introduces a configuration method of the Temporary Permitted Rate (TPR). By using this new configuration method of TPR, IN packets of greedy TCP flows are re-marked to OUT packets pertinently and constantly whenever the network traffic changes. Simulation Results show that this novel re-marking strategy can regulate the packet transmission rate of each TCP flow to the contract rate without a decrease in the link utilization.

In this paper reviewed are the past studies on the plate forming and introduced is the computer aided marking data generation system which should precede the automation system for plate forming by line heating method. The developed computer aided marking data generation system has been applied to a real surface which is frequently found in the bow and the stern area of a ship. From its application results, the estimated surface by the present marking data generation system is very close to the given surface and the generated marking data also shows reasonably good agreement with those in the real practice in ship yard at present. shows very good agreement. When the marking data generation system has been complemented through more applications to real surface models, then it can be practically used in the real practice in ship yard.

There is no overall understanding about the road marking situation in Korean national highway nowadays. In addition road marking increases risk in traffic accidents especially while it's raining at night because of diffused reflection. So administrator has a lot of problems to maintain and make a decision about the road marking. In this paper, literature review and field investigation about the road marking are carried out from the viewpoint of road safe and the propriety in retroreflective performance of the road marking is grasped. Also, improvement methods about retroreflective performance of the road marking are proposed on the basis of the result in field investigation.

This paper proposes an algorithm of CAD data extraction for the computer controlled marking system. In general, logo has been directly designed at the marking controller, but that is not an effective method because of the very limited working area. In this paper, for the data extraction we used a general PC and Auto CAD for logo design, and developed the software with GUI(Graphic User Interface) method. Then the data is transferred to the marking controller for marking on the object. With experimental result we showed the proposed algorithm to be very effective in the computer controlled marking system.

In this paper, laser marking systems dedicated to cylinderical parts was developed. We first develop the marking device which consists of Nd-Yag laser, galvano scanner and additional rotational axis, then develop algorithm for supporting the digital image with bmp data format. Additional rotational axis is so attached as to rotate the cylinderical parts for marking its whole surface. The image is separated into line by line and the separated line image is sent to galvano scanner while rotating the additional axis simultaneously. CxImage library, famous open source code, is employed for the image processing. The developed method was tested with various images and shows that it reduces marking time significantly without reducing marking quality.

The laser marking system is widely used in many industrial manufacturing companies as an effective process, because it is versitile, clean, and fast to run. Minimal heat deformation and zero tool wear can be obtained using fast and non-contact process of laser marking. As an introductory level, the basic knowledges about laser marking system layout and its components are presented with diagrams. The effects, requirements, and application example of laser marking process are also described in this paper.

Since seagrasses are highly productive and provide a source of organic carbon for a wide variety of marine organisms in coastal and estuarine ecosystem, accurate assessment of seagrass production is critical to understand the functions and values of seagrasses in these ecosystems. Zieman's leaf marking technique has been mostly used to estimate seagrass leaf production rates. However, inherent problems on the traditional leaf marking technique have been discussed by the several researchers, and these problems can cause underestimation of seagrass production. To develop an accurate and reliable assessing method for seagrass production, production rates of eelgrass, Zostera marina in three bay systems on the south coast of the Korean peninsula were estimated using the conventional leaf marking technique and the plastochrone method. The plastochrone method has been recently suggested as an effective method for reliable assessments of seagrass production. In the present study, leaf production rates estimated by the plastochrone method were significantly higher than the rates derived from the traditional leaf marking technique. Annual eelgrass leaf production assessed using the leaf marking technique was about 65 to 89% of the estimated production using the plastochrone method. The differences in annual productions between assessment techniques imply that the conventional leaf marking technique significantly underestimated eelgrass leaf production. Total eelgrass productions estimated using the plastochrone method in the present study sites were about 600 to 806 g DW $m^{-2} y^{-l}$, and below-ground production accounted for about 20 to 23% of the total production. The plastochrone method was suggested to be an effective and accurate assessing method for eelgrass production.
