The present study was designed to develop the standardized formula for the preparation Jeung-Pyun with added raw soy flour and to investigate the applicability of Jeung-Pyun as the substitute of regular pizza crust made with wheat flour. The effect of adding raw soy flour at 3%, 5% level on fermentation time and viscosity of batters and texture and general desirability of Jeung-Pyun pizza were also studied. As the level of raw soy flour was increased the time required for 1 st and 2nd fermentation decreased and viscosity of batters increased significantly. Jeung-Pyun crust after steaming found to have appropriate texture and form for a substitute of wheat flour pizza crust. Texture parameters determined by QST showed that Jeung-Pyun crust with added raw soy flour had lower values in hardness, cohesiveness and gumminess without any significant difference. However, chewiness of 5% raw soy flour group was significantly lower than control group. Texture of Jeung-Pyun crust and general desirability of Jeung-Pyun pizza were determined by sensory evaluation. Textural parameters of Jeung-Pyun crust were evaluated on the basis of hardness, cohesiveness, adhesiveness, tenderness and wetness. As a result of sensory evaluation Jeung-Pyun crust made with 5% raw soy flour had significant lower values in hardness, cohesiveness, tenderness and wetness than the control. However, the textural parameters between control and 3 % raw soy flour group were not significantly different. Jeung-Pyun pizza with topping were evaluated by sensory panel. Jeung-Pyun pizza made with 3% raw soy flour received the highest score in apperance and general desirability without any significant difference. 5% raw soy flour group had significantly lower score in general desirability among 3 treatment groups. In conclusion, Jeung-Pyun crust made by traditional Jeung-Pyun preparation method will be a good alternative to replace wheat flour pizza crust. Adding raw soy flour at 3% level did not affect the quality of Jeung-Pyun crust and had an effect of promoting fermentation. Jeung-Pyun Pizza crust was expected to have tender texture and slower retrogradation rate than regular pizza crust with wheat flour.

This study was carried out to estimate the effects of glucono-$\delta$-lacton (GDL) on prolongation of shelf-life on Kimchi. Final concentration of added GDL was determined 0.3% according to the result of sensory evaluation. Chemical characteristics and microbiological parameters were monitored during fermentation at 1$0^{\circ}C$. GDL Kimchi showed the initial sharp decrease in pH and gradually increase of pH due to osmotic pressure and then the pH of GDL Kimchi was slowly decreased compared with that of control Kimchi during fermentation. The acidity of control Kimchi was markedly increased around pH 4.5 by growth of microorganism. Otherwise, GDL Kimchi showed that t]le formation of organic acids was slow and little amount compared with that of control Kimchi. HPLC analysis showed oxalic acid, lactic acid, acetic acid, malic acid and succinic acid appeared by fermentation. The production of lactic acid changed a lot in control Kimchi, where as little in GDL Kimchi. Growth of L. mesenteroides at initial stage of Kimchi fermentation was remarkably inhibited by adding 0.3% GDL. It retarded also the growth of L. Plantarum and L. breuis at late stage of Kimchi fermantation and led to reduce the softening of texture and retard over ripening of Kimchi. Tn sensory evaluation of Kimchi, GDL Kimchi showed the similar characteristics to the control Kimchi. This result suggested that GDL can be successfully used for the prolongation of shelf-life and sensory evaluation on Kimchi.

The aim of the research is to analyze the feasibility of rapid quality evaluation method for blast furnace slag using hydrometer based on the former research of the prediction method for concrete compressive strength using hydrometer. Using this method, it is expected to provide a new application for blast furnace slag quality evaluation easily and rapidly during the receiving inspection. According to the experimental results, the settling time period of hydrometer was delayed with increased fineness of blast furnace slag. By using the regression equation of y = 198 120 x - 193 936(R=0.9398) obtained from the correlation between density of suspension at three minutes and fineness, it was possible to evaluate the quality of blast furnace slag fineness rapidly. Therefore, for ready-mixed concrete receiving inspection, the suggested method can be used as a cheap, a simple, and a rapid inspection method.

A conventional phased array system can control an ultrasonic beam electronically by adjusting the excitation time delay of individual elements in a multi-element probe and produce an ultrasonic image. In Contrast, full matrix capture (FMC) is a data acquisition process that allows receiving ultrasonic signals from one single shot of the phased array transducer element through all the other elements and captures the complete dataset from every possible transmit-receive combination. This FMC data can be used to create the ultrasonic image in post processing. It is possible to produce not only images equivalent to conventional phased array image but also total focusing method (TFM) images with improved resolution and sharpness, which is virtually focused at any point in a region of interest. In this paper, the system that can perform FMC by using a conventional phased array instrument is developed, and a study was conducted on the imaging algorithms to reconstruct sector B-scan and TFM images from FMC dataset.

A conventional phased array ultrasonic system offers the ability to steer an ultrasonic beam by applying independent time delays of individual elements in the array and produce an ultrasonic image. In contrast, full matrix capture (FMC) is a data acquisition process that collects a complete matrix of A-scans from every possible independent transmit-receive combination in a phased array transducer and makes it possible to reconstruct various images that cannot be produced by conventional phased array with the post processing as well as images equivalent to a conventional phased array image. In this paper, a basic algorithm based on the LLL mode total focusing method (TFM) that can image crack type flaws is described. And this technique was applied to reconstruct flaw images from the FMC dataset obtained from the experiments and ultrasonic simulation.

The purpose of this study was to evaluate the value of dacryoscintigraphy with Tc-99 m Pertechnetate, which is useful in functional nasolacrimal duct obstruction diagnosis in human medical science, by applying it to normal dogs. Dacryoscintigraphy was performed on six clinically healthy beagle dogs to confirm normal passage of their lacrimal ducts. The scintigraphic images of both lacrimal system were obtained at 5 min, 10 min, and 20 min after Tc-99 m Pertechnetate administration, respectively. If lacrimal duct does not come into view within 20 min, delayed images at 30min, 45min and 60 min were gained. After drawing ROI of left and right canaliculus, lacrimal sac, and nasolacrimal duct acquired after dacryoscintigraphy, we measured each counting rate and developed a counting rate table for each time interval. Of the total of 12 places, 10 (83.3%) showed patency within 20 min, and 11 (91.6%) showed patency within 30 min. In one dog, a functional obstruction of right lacrimal canal was observed. Dacryoscintigraphy could provide useful information about functional and anatomical lacrimal duct obstruction in veterinary medicine as well as in clinical research.

For playing a multimedia presentation in a Internet, the case that the presentation QoS(Quality of Services) at a destination nay be different from the QoS of multimedia data at the source occurs frequently. In this case, the process of trancoding the multimedia data at the source Into the multimedia data satisfying the QoS at the destination should be requited. In addition, even the presentation description having the homogeneous QoS at both sides may have different transcoding paths due to the limitation of display terminals or network bandwidth. That is, for a multimedia description, it is required to regenerate a proper transcoding path whenever the displaying terminals or the network environment gets decided. And the delay time required to go through the transcoding path may affect the playability of the give presentation. Therefore it should be checked whether the presentation requiring a transcoding process is able to be played in a real time. In this paper, the algorithm for generating all the possible transcoding paths for a given multimedia description under a fixed set of transcoders and the network environment is proposed. The algorithm adopts the concept of QoS transition diagram to Prevent from a trancoding Path being cycled by the repetition of a cyclic Path which generates the same QoS of multimedia data as its input QoS. By eliminating all the cyclic Paths, the algorithm can guarantee the termination of the process. And for the playability check, a method of computing the transcoding time and the delay lime between logical data units are proposed.Finally all the proposed methods were implemented in the stream engine, called TransCore and the presentation-authoring tool, called VIP, we had developed. And the test results with sample scenarios were presented at the last.
