This study proposes the improvement of the system based on a result of a certain practice. As contemporary higher education information environments transform, this study highlights the significance of university identity and college identity that are formed continuously through independent activities of the students. Based on these discussions, the present study proposes a practical media environment design which facilitates the processes of organizational identity formation based on a continuous and cyclical model. Even if users change by this system, the communication system continues operation and cooperation. The activity becomes the archive and produces new activity. Based on the result, this study elaborates a plan with a re-design by a system from the viewpoint of second-order cybernetics. Systems theory is a theoretical foundation for our study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20work" title="collaborative work">collaborative work</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20management%20system" title=" learning management system"> learning management system</a>, <a href="https://publications.waset.org/abstracts/search?q=second-order%20cybernetics" title=" second-order cybernetics"> second-order cybernetics</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20theory" title=" systems theory"> systems theory</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20generated%20contents" title=" user generated contents"> user generated contents</a>, <a href="https://publications.waset.org/abstracts/search?q=viable%20system%20model" title=" viable system model"> viable system model</a> </p> <a href="https://publications.waset.org/abstracts/91229/design-of-collaborative-web-system-based-on-case-study-of-pbl-support-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91229.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Interaction of Glycolipid S-TGA-1 with Bacteriorhodopsin and Its Functional Role </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masataka%20Inada">Masataka Inada</a>, <a href="https://publications.waset.org/abstracts/search?q=Masanao%20Kinoshita"> Masanao Kinoshita</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobuaki%20Matsumori"> Nobuaki Matsumori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been demonstrated that lipid molecules in biological membranes are responsible for the functionalization and structuration of membrane proteins. However, it is still unclear how the interaction of lipid molecules with membrane proteins is correlated with the function of the membrane proteins. Here we first developed an evaluation method for the interaction between membrane proteins and lipid molecules via surface plasmon resonance (SPR) analysis. Bacteriorhodopsin (bR), which was obtained by the culture of halobacteria, was used as a membrane protein. We prepared SPR sensor chips covered with self-assembled monolayer containing mercaptocarboxylic acids, and immobilized bR onto them. Then, we evaluated the interactions with various lipids that have different structures. As a result, the halobacterium-specific glycolipid S-TGA-1 was found to have much higher affinity with bRs than other lipids. This is probably due to not only hydrophobic and electrostatic interactions but also hydrogen bonds with sugar moieties in the glycolipid. Next, we analyzed the roles of the lipid in the structuration and functionalization of bR. CD analysis showed that S-TGA-1 could promote trimerization of bR monomers more efficiently than any other lipids. Flash photolysis further indicated that bR trimers formed by S-TGA-1 reproduced the photocyclic activity of bR in purple membrane, halobacterium-membrane. These results suggest that S-TGA-1 promotes trimerization of bR through strong interactions and consequently fulfills the bR’s function efficiently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membrane%20protein" title="membrane protein">membrane protein</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid" title=" lipid"> lipid</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteriorhodopsin" title=" bacteriorhodopsin"> bacteriorhodopsin</a>, <a href="https://publications.waset.org/abstracts/search?q=glycolipid" title=" glycolipid"> glycolipid</a> </p> <a href="https://publications.waset.org/abstracts/72463/interaction-of-glycolipid-s-tga-1-with-bacteriorhodopsin-and-its-functional-role" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72463.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Effect of Burdock Root Extract Concentration on Physiochemical Property of Coated Jasmine Rice by Using Top-Spay Fluidized Bed Coating Technique </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Donludee%20Jaisut">Donludee Jaisut</a>, <a href="https://publications.waset.org/abstracts/search?q=Norihisa%20Kato"> Norihisa Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanutchaporn%20Kumrungsee"> Thanutchaporn Kumrungsee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiyoshi%20Kawai"> Kiyoshi Kawai</a>, <a href="https://publications.waset.org/abstracts/search?q=Somkiat%20Prachayawarakorn"> Somkiat Prachayawarakorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Patchalee%20Tungtrakul"> Patchalee Tungtrakul </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Jasmine Rice is a principle food of Thai people. However, glycemic index of jasmine rice is in high level, risk of type II diabetes after consuming. Burdock root is a good source of non-starch polysaccharides such as inulin. Inulin acts as prebiotic and helps reduce blood-sugar level. The purpose of this research was to reduce digestion rate of jasmine rice by coating burdock root extract on rice surface, using top-spay fluidized bed coating technique. Coating experiments were performed by spraying burdock root solution onto Jasmine rice kernels (Khao Dawk Mali-105; KDML), which had an initial moisture content of 11.6% wet basis, suspended in the fluidized bed. The experimental conditions were: solution spray rates of 31.7 mL/min, atomization pressure of 1.5 bar, spray time of 10 min, time of drying after spraying of 30 s, superficial air velocity of 3.2 m/s and drying temperatures of 60°C. The coated rice quality was evaluated in terms of the moisture content, texture, whiteness and digestion rate. The results showed that initial and final moisture contents of samples were the same in concentration 8% (v/v) and 10% (v/v). The texture was insignificantly changed from that of uncoated sample. The whiteness values were varied on concentration of burdock root extract. Coated samples were slower digested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=burdock%20root" title="burdock root">burdock root</a>, <a href="https://publications.waset.org/abstracts/search?q=digestion" title=" digestion"> digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a> </p> <a href="https://publications.waset.org/abstracts/60231/effect-of-burdock-root-extract-concentration-on-physiochemical-property-of-coated-jasmine-rice-by-using-top-spay-fluidized-bed-coating-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60231.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Investigating the English Speech Processing System of EFL Japanese Older Children </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiromi%20Kawai">Hiromi Kawai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the nature of EFL older children’s L2 perceptive and productive abilities using classroom data, in order to find a pedagogical solution to the teaching of L2 sounds at an early stage of learning in a formal school setting. It is still inconclusive whether older children with only EFL formal school instruction at the initial stage of L2 learning are able to attain native-like perception and production in English within the very limited amount of exposure to the target language available. Based on the notion of the lack of study of EFL Japanese children’s acquisition of English segments, the researcher uses a model of L1 speech processing which was developed for investigating L1 English children’s speech and literacy difficulties using a psycholinguistic framework. The model is composed of input channel, output channel, and lexical representation, and examines how a child receives information from spoken or written language, remembers and stores it within the lexical representations and how the child selects and produces spoken or written words. Concerning language universality and language specificity in the language acquisitional process, the aim of finding any sound errors in L1 English children seemed to conform to the author’s intention to find abilities of English sounds in older Japanese children at the novice level of English in an EFL setting. 104 students in Grade 5 (between the ages of 10 and 11 years old) of an elementary school in Tokyo participated in this study. Four tests to measure their perceptive ability and three oral repetition tests to measure their productive ability were conducted with/without reference to lexical representation. All the test items were analyzed to calculate item facility (IF) indices, and correlational analyses and Structural Equation Modeling (SEM) were conducted to examine the relationship between the receptive ability and the productive ability. IF analysis showed that (1) the participants were better at perceiving a segment than producing a segment, (2) they had difficulty in auditory discrimination of paired consonants when one of them does not exist in the Japanese inventory, (3) they had difficulty in both perceiving and producing English vowels, and (4) their L1 loan word knowledge had an influence on their ability to perceive and produce L2 sounds. The result of the Multiple Regression Modeling showed that the two production tests could predict the participants’ auditory ability of real words in English. The result of SEM showed that the hypothesis that perceptive ability affects productive ability was supported. Based on these findings, the author discusses the possible explicit method of teaching English segments to EFL older children in a formal school setting. <p
