  • The results of process development for the blending of waste salt from the electrorefining of spent fuel with zeolite-A are presented. This blending is a key step in the ceramic waste process being used for treatment of EBR-II spent fuel and is accomplished using a high-temperature v-blender. A labscale system was used with non-radioactive surrogate salts to determine optimal particle size distributions and time at temperature. An engineering-scale system was then installed in the Hot Fuel Examination Facility hot cell and used to demonstrate blending of actual electrorefiner salt with zeolite. In those tests, it was shown that the results are still favorable with actinide-loaded salt and that batch size of this v-blender could be increased to a level consistent with efficient production operations for EBR-II spent fuel treatment. One technical challenge that remains for this technology is to mitigate the problem of material retention in the v-blender due to formation of caked patches of salt/zeolite on the inner v-blender walls.

  • The novel microsphere blending and multiple emulsion method by single process was tried to prepare sustained release microspheres which release a physiologically active substance for long periods of time. A drug was separately dissolved in each of two or more oils containing biodegradable polymers to give the primary oil phases. The primary oil phases were dispersed in single aqueous phase in succession. From the drug-dispersed solution, the organic solvent was removed to produce microspheres. The accelerated drug release from the microsphere formulation prepared by single process through the multiple emulsion method was very similar to a physical blending of separately prepared microspheres using the same polymers. But long term release was not same. In this study, leuprorelin acetate loaded poly(lactide-co-glycolide) microsphere formulation for one-month delivery was developed by the multi-emulsion method followed by solvent extraction/evaporation method.

  • This treatise makes clear not only a structural methodology of 'the conceptual blending theory' using in a linguistics could be applied to the similar process in a hybrid design but also both methods include the same meaning construction in the sense of a mutual educational system. Both methods have something in common that they are fundamentally focused on a metaphorical expression which implies poetic messages to be concentrated on a formal structure. Therefore, the purpose of this treatise is to examine the structural characteristics in the hybrid design in order to analyze the rhetorical expressions(metaphor, allegory) as symbols of communication. One of the those is intertextuality that expresses metaphorically by blending and borrowing codes and another is hypertextual space where various texts twines around each other making brand-new and diverse organizations, as the combined allegory with a number of hidden expression. Ultimately, it is important that this approach could verify whether it deals the illogical present state of a spacial form or structure with a kind of mechanism of a 'conceptual blending theory' or not.

  • This study focused on the direct blending of bonding agents (resorcinol, hexamethylenetetramine, NaOH) into rubber compound to simplify the composite manufacturing process. The mechanism of direct blending system was studied by comparing the following two cases. The one is direct blending of bonding agents into rubber compound and then allows the reaction (Case I). The other is mixing of reactant obtained by reaction of bonding agents (Case II). According to the morphology analysis, the Case II showed the clean interfacial area between bonding agents and matrix rubber, while the Case I created the new interphase under proper processing condition. Also, the optimum adhesion strength between SBR and nylon cord could be obtained with bonding agents whose molar ratios of resprcinol/hexamethylenetetramine was 1.2/1 in the recipes.

  • This paper investigates the possibility to increase the economic value of the thinned young apple trough fermentation process. It is studies the optimal fermentation condition of thinned young apple by manipulating preparation treatment and sugar content. To do this following steps are done. Firstly, different preparation treatment for thinned young apple such as whole apple, cutting apple, and blending apple were done. The different sugar content such as $24^{\circ}Brix$, $15^{\circ}Brix$ and $4^{\circ}Brix$ was added. Secondly, the sugar contents and pH level were measured during fermentation process. Finally, statistical analysis was used to examine the relation between the preparation treatment, sugar content and pH level during the fermentation process. The experimental result shows that the different preparation treatment influences to the fermentation process. The blending apple treatment gave lower pH level compared to other kind treatments. The sugar content of thinned young apple was decrease during the fermentation process. The statistical analysis shows that the manipulation preparation treatment and sugar content affect the final pH level and whole fermentation process. Experimental result shows that the thinned young apple fermentation could be proposed as new alternative product in the market. The best fermentation process was obtained from blending thinned young apple treatment with $24^{\circ}Brix$.

  • In essence, Musical theatre is a multimedia show, so when you listen to musical numbers, you will experience it through multiple senses. Therefore, in order to analyze musical numbers, emphasis should be placed on its interaction with various media such as lyrics, dance, and theatre, which have a direct association with the music. Through the Conceptual Blending Theory, which can comprehensively consider the combination of text and music, the combination of movement and music, and the combination of visual elements and music, this study analyzes the music of Musical . By exploring the result of interaction between lyrics and music, the interaction between choreography and music, and the interaction between stage and music, the artistry and intrinsic value of the work can be proved. In addition, we can discover the process and system of integrated interpretation through music analysis applying Conceptual Blending Theory. Therefore, Conceptual Blending Theory has sufficient utility as a methodology for music analysis of musical theatre.

  • In this paper, PVA(polyvinylalcohol), oxidized starch and SBR latex were used as binders for ink-jet printing papers, and their effects of the type and blending ratio of binders on ink-jet printing properties were compared. In case of coating color using PVA mainly used for a binder in ink-jet printing, spreading of printed letters decreased and excellent images were manifested resulting from strong hydrophilic of PVA. However, increasing solids content of coating color was somewhat limited because of the interaction of PVA and functional groups in silica as well as high molecular weight of PVA. When oxidized starch and SBR latex were mixed with PVA at desirable ratio to solve these problems, runnability in coating process was improved and good printing properties were shown. Gloss was improved when latex was used along with PVA as a binder because of the thermoplastic property of the latex. From this result, possibilities of high solids content and high gloss ink-jet printing papers were investigated.

  • The fibrogram theory is newly derived from the superposition principle of the conventional staple diagram, in which the left-hand ends of the fibers have to share a common starting point in order for the fiber length distribution to be measured, and the right-hand ends of the fibers form points. It is shown that the fibrogram is the staple diagram of the fiber sample having different random starting points, as well as the double cumulative distribution function of the frequency length function in the length biased sample. Also, the various means, viz. the numerical mean length, numerical mean length in median, length biased mean length, and length biased mean length in median, and the various upper half means, viz. the numerical upper half mean length, numerical upper half mean length in median, length biased upper half mean length, and length biased upper half mean length in median, are discussed in relation to the cotton blending process.

  • Nowadays blending ratio of OMG (old magazine) in recovered paper used for manufacturing newspaper have been increased. When large amount of OMG is consumed in newsprint mill, brightness can be improved by inorganic pigments of coating layer. On the other hand decrease in yield of deinking process will be encountered because the pigments can be removed as reject of froth flotation process. Therefore selection of the optimal deinking agent is an important. Non-ionic surfactant have been used widely in newsprint mill. Non-ionic surfactant has amphoteric characteristics. Hydrophilic group is ethylene and propylene oxide that can induce hydrogen bonding with water molecules. In this regard, cloud point is an important parameter in order to control efficiency of deinking process because hydration of the hydrophobic group can be varied according to temperature of a system. In this study, deinking properties of ONP at high blending ratio of OMG was analyzed according to cloud points of non-ionic surfactants. $L^*$, $a^*$, $b^*$, brightness and effective residual ink concentration did not affected by the change of cloud points. Especially, flotation reject decreased significantly according to increase in cloud point of the non-ionic surfactant. Consequently, when a nonionic surfactant having a cloud point higher than the temperature of the system is used, properties of the deinked pulp can be maintained and yield of deinking process can be improved.

  • In this paper, we propose a novel seamless video composition method based on shape matching and Poisson equation. Video composition method consists of video segmentation process and video blending process. In the video segmentation process, the user first sets a trimap for the first frame, and then performs a grab-cut algorithm. Next, considering that the performance of video segmentation may be reduced if the color, brightness and texture of the object and the background are similar, the object region segmented in the current frame is corrected through shape matching between the objects of the current frame and the previous frame. In the video blending process, the object of source video and the background of target video are blended seamlessly using Poisson equation, and the object is located according to the movement path set by the user. Simulation results show that the proposed method has better performance not only in the naturalness of the composite video but also in computational time.
