The effects and interactions of $4{\beta}-phorbol$ 12,13-dibutyrate(PDB) and polymyxin B(PMB) with adenosine on the electrically-evoked norepinephrine (NE) release were studied in the rat hippocampus. Slices from the rat hippocampus were equilibrated with $^3H-noradrenaline$ and the release of the labelled product, $^3H-NE$, which evoked by electrical stimulation$(3\;Hz,\;2\;ms,\;5\;VCm^{-1},\;rectangular\;pulses)$ was measured. PDB$(0.3{\sim}10\;{\mu}M)$, a selective protein kinase C(PKC) activator, increased the evoked NE release in a dose related fashion while increasing the basal rate of release. And the effects of $1\;{\mu}M$ PDB were significantly inhibited by $0.3\;{\mu}M$ tetrodotoxin(TTX) pretreatment or $Ca^{++}-free$ medium. $PMB(0.03{\sim}1\;mg)$, a specific PKC inhibitor, decreased the NE release in a dose dependent manner while increasing the basal rate of release. Adenosine $(1{\sim}10\;{\mu}M)$ decreased the NE release without changing the basal rate of release, and this effect was significantly inhibited by 8-cyclopentyl-1,3-dipropylxanthine$(2\;{\mu}M)$, a selective $A_1-receptor$ antagonist, treatment. Also, adenosine effects were significantly inhibited by PDB-and PMB-pretreatment. These results suggest that the PKC plays a role in the NE release in the rat hippocampus and might be participated in a post-receptor mechanism of the $A_1-adenosine$ receptor.

The purpose of this study is to examine losely how the Rococo style, which reached its summit in the history of French furniture, was realized in its social background and mode of life. Based ion this examination , this study will explore desirable directions for developing our domestic furniture design. For this purpose , existing literature will be referred to and analyzed to arrange into a new system. Rococo furniture style was the product of joyous and aristocratic living . This was based upon the historical development of French interior design, established by the national mode of Versailles Palace. Hereafter, royal style came into fashion paralleled with the luxuries of the court. Pursuit of new , interesting or beyond-expectation fashions encouraged the creation of new and imaginative forms and designs . The elegnant taste of customers, the new techniques of furniture manufacturing , and the unique sales strategies of merchants were social phenomena which contributed to the development of Rococo furniture. Furthermore , Louis XV`s private and personal life led to society`s pursut of comfortable and convenient living . Under these circumstances, small and cozy rooms for various uses came into the interior. Accordingly, the scales of furniture became smaller and any types of furniture with their own uses and feminine nature were manufactured , especially by the bnistes. Rococo furniture with fmine beanty and refined line, beatifil proportion and elegant sculpture, and solidity and clarity in general , is not only furniture for the use of man, but also furniture in harmony with man. As we see the stages of development and the characteristics of Rococo furniture, development of Korean furniture is a common task which can be accomplished through the participation of the designer, manufacturer, seller and consumer. Based on this co-operation , the furniture industry must make an improvement in furmture design, lestablish a permanent store in which new works are displayed. publicize activities and sales, promote exhibitions and seminars, and encourage technical development through the government and other interested organizations.

Membrane electrode assembly (MEA) for polymer electrolyte fuel cell (PEFC) are commonly prepared in the research laboratory by spraying, screen-printing and brushing catalyst slurry onto membrane or other support material like carbon paper or polyimide film in a batch style. These hand applications of the catalyst slurry are painstaking process with respect to precision of catalyst loading and reproducibility. It has been generally mentioned that the adoption of continuous process is very helpful to develop the reliable product. In the present work, we report the results of using continuous type coater with doctor-blade to coat catalyst slurry for preparing the MEA catalyst layers In a faster and highly reproducible fashion. We show that while expectedly faster than batch style, the machine coater requires the use of slurry of appropriate composition and a properly selected transfer decal material in order to achieve superior MEA plat lnw loading reproducibility. To make highly viscous catalyst slurry that is imperative for using coater, we use 40wt.% Nafion solution and minimize the content of organic solvent. And the choice of proper high surface area catalyst is important in the viewpoint of making well-dispersed slurry. After catalyst coating onto the support material, we transferred the catalyst layer to both sides of Nafion membrane by hot-pressing In this case, the degree of transfer was Influenced by hot-pressing condition including temperature, pressure, and time. To compare the transferring ability, we compared so many films and detaching papers. And among the support, polyethylene terephthalate(PET) film shows the prominent result.

Purpose: The main purpose of this study is to analyze the case of the transparent PET bottle resource circulation project of BYN Black Yak Co., Ltd., present implications, and propose ways to spread it in the future. Methods: In this study, the logic of the Double Diamond Model is applied to analyze the development process of sustainable fashion made from BYN Black Yak Co., Ltd.'s PET Bottle Resource Circulation System. Results: The K-rPET Resource Circulation Project of BYN Black Yak Co., Ltd. is recognized as a best example for its contribution to eco-friendly activities, solving social problems, raising consumer awareness, and sharing recycling habits. Before the plastic bottle becomes a garment, five steps are taken (discharge of PET bottle → collection of PET bottle → recycling of PET bottle → fabrication of yarn → production of the finished product out of the fabric). BYN Black Yak Co., Ltd. has successfully commercialized it by recycling reverse-recovery PET bottles by making solutions to problems that have not been solved at each stage. Conclusion: In addition to efforts to find and strengthen weak links presented in the Theory of Constrains (TOC), it appears to have systematically carried out activities to convert stakeholder discomforts into a package of gain points. As shown in the slogan "We are all in!" the proposal and implementation for the completion of a true environmental system is judged to have truly performed ESG management well for the company's business. ESG management activities at BYN Black Yak Co., Ltd. are expected to continue.

Consumers' interests in the environment have been growing; hence, their consciousness about the environment has changed and affected their clothing shopping behavior. Prior study indicated attitude-behavior inconsistency in eco-friendly consumer behavior. It was because consumers' consciousness or attitude was often measured at an abstract level, not at a product specific level. This study investigated eco-friendly clothing knowledge, eco-friendly clothing consciousness, and ecological clothing consumption behavior. The effects of consumers' level of clothing involvement and subjective norms in this process were also investigated. For the empirical research, a questionnaire was developed, and responses from 480 women in their 20s to 50s were statistically analyzed. Results indicated that interest and fashion consciousness dimensions of clothing involvement had a significant influence on eco-friendly clothing knowledge, which thereby significantly influenced the three factors of eco-friendly clothing consciousness: social responsibility, health orientation, and clothing resource-saving consciousness. Such factors had different roles in the clothing consumption process. Social responsibility had a significant influence on the entire process of clothing consumption: shopping, purchasing, using, and disposing behaviors. Health orientation consciousness had a significant influence on shopping and purchasing behaviors, whereas resource-saving consciousness had a significant impact only on shopping behavior. Subjective norms were significantly correlated with all aspects of the clothing consumption process. Influence on disposing behavior was relatively weaker than other aspects of clothing consumption behavior.

Background: Artificial grafts such as polyethylene terephthalate (Dacron) and expanded polytetrafluoroethylene (ePTFE) are used for various cardiovascular surgical procedures. The compliance properties of prosthetic grafts could affect hemodynamic energy, which can be measured using the energy-equivalent pressure (EEP) and surplus hemodynamic energy (SHE). We investigated changes in the hemodynamic energy of prosthetic grafts. Methods: In a simulation test, the changes in EEP for these grafts were estimated using COMSOL MULTIPHYSICS. The Young modulus, Poisson ratio, and density were used to analyze the grafts' material properties, and pre- and post-graft EEP values were obtained by computing the product of the pressure and velocity. In an in vivo study, Dacron and ePTFE grafts were anastomosed in an end-to-side fashion on the descending thoracic aorta of swine. The pulsatile pump flow was fixed at 2 L/min. Real-time flow and pressure were measured at the distal part of each graft, while clamping the other graft and the descending thoracic aorta. EEP and SHE were calculated and compared. Results: In the simulation test, the mean arterial pressure decreased by 39% for all simulations. EEP decreased by 42% for both grafts, and by around 55% for the native blood vessels after grafting. The in vivo test showed no significant difference between both grafts in terms of EEP and SHE. Conclusion: The post-graft hemodynamic energy was not different between the Dacron and ePTFE grafts. Artificial grafts are less compliant than native blood vessels; however, they can deliver pulsatile blood flow and hemodynamic energy without any significant energy loss.
