Bilinear approximation used in the derivation of the memory function of mode-coupling theory (MCT)is reviewed and reconsidered by means of an operator identity . Within two-body approximation, a correction partis derived from usually neglected part from the fluctuating force of MCT. Finally, a modified MCT equation,which is able to adjust the glass transition temperature to more accurate point than that of ordinary MCT, is derivedon several assumptions.

The synergistic extraction of Gadolinium(III) has been studied to the porous resin impregnated with amixture of LIX 51, and a neutral ligand, 4,7-dimethyl-1,10-phenanthroline (dmp). The synergistic enhancementof the extraction of Gd(III) occurred by the addition of dmp in the impregnated resin system as well as the solventextraction system. The maximum amount of the extracted Gd(III) was almost consistent with the calculated valuefrom amounts of reagents held in the resin. The recovery of Gd(III) extracted with the resin, and the reuse of theimpregnated resin was also discussed.

A noble system, which can recognize both finger and gesture signs and can synthesize theircorresponding voice, has been developed, in order to enable people unfamiliar with a sign language to make aconversation with hearing-handicapped persons. Finger and gesture signs are sensed both with bending andacceleration sensors. Acquired sensor data are transferred through wireless sensor networks to a host computer.Finger signs are recognized from bending information of finger, and gesture signs are discriminated by analyzingarm's movements by hidden Marcov model method. Finally, recognized signs are converted into correspondingvoices by a free software of Aques Talk or PWM function of microcomputers. As a result of evaluation, it has beenproved that 60-100% of finger signs and more than 90% of gesture signs consisting of six kinds of gesture aresuccessfully discriminated and converted into voices.

We prepared the TiO2 thin film electrodes for artificial photosynthesis by using the RF magnetronsputtering method. The TiO2 thin films deposited on MgO, LaAlO3, Al2O3, LaSrAlTaO and SrTiO3 single crystalsubstrates had an anatase, rutile and brookite crystal structures. We found that the crystal structure of TiO2 thinfilms depends on deposition conditions, such as total sputtering pressure, substrate materials and crystal planes ofsubstrate surface.

Resorcinol cyclic tetramer (n-Host) interacts with polar organic compounds such assugars, alcohols and carboxylic acids via multiple hydrogen-bonding. The host also extractsniacins from its water solution to a nonpolar organic solvent via same manner. Niacins used arenicotinamide, isonicotinamide, picolinamide, nitcotinic acid, isonicotinic acid, and nicotinamidederivative compounds. Extraction rate of niacins increases in order of affinity of host-guestinteraction. Especially, n-Host interacts strongly with nicotinamide via double hydrogen-bondinginteraction, because amide group and N-atom on pyridine of nicotinamide are able to interactconveniently with binding-sites of n-Host. On the contrary, n-Host interacts weakly withisonicotinamide, because amide group and N-atom on pyridine aren't able to interact simultaneouslywith n-Host.

In order to improve the giving hydrophilicity of poly(vinyl chloride) (PVC) and to synthesizethree-dimensional PVC gel, I prepared novel telechelics having the reactive groups on the both ends, and graftedthose onto PVC. This grafting was performed by substitution of chlorine atoms of PVC with triazinethiols oftelechelic poly(2-alkyl-2-oxazoline)s (PROZO). The substitution of PVC was experimentally conducted by twomethod, using thiol type telechelics with potassium carbonate, or sodium thiolate type telechelics in1-methyl-2-pyrrolidone. The results indicated that the rate of substitution, the degree of introduction of graft chains,grafting and the molecular weight are controllable by kinds of alkyl groups in the telechelics, the feed ratio, and thereaction temperature.

The titanium oxide aerogel as photocatalyst was prepared by supercritical carbon dioxide drying to remove solvent alcohol, followed by crack-free wetting gel synthesis of sol-gel method. Titanium alkoxide, 2-propanol, water, and HCl compositions were optimized to find the best molar ratio for the synthesis of crack-free aerogel. We also introduced dimethylformamide (DMF) as a drying control reagent into the synthesis of wetting gels. Wetting-gel cracks were inhibited quantity of the suitable HCl, and DMF concentration. The aging with high temperature and long aging time do not improve aerogel properties. The mass of consumed CO2, and CO2 flow rate are important parameter to prevent crack and shrink on the aerogel. The drying of wetting gel finished by using CO2 volume 10000 g-CO2/g-wetting gel during the weight of dried gel approached that of TiO2 aerogel. Preparation parameters such as drying procedure influence on aerogel properties revealed by means of X-ray diffraction, acetaldehyde decomposition profile, and transmission electron microscope. The x-ray diffraction analysis of calcinated aerogel identified as anatase phase of titanium oxide.

Enterococcal surface protein (esp) gene in Enterococcus faecium was used as an indicator of humanfecal pollution. A real-time PCR could not detect the esp gene directly in wastewater sample and in any enterococciisolated from sewage influent. Contrastingly, the uidA gene specific to Escherichia coli was detected in wastewatersample, and shown to be useful indicator of fecal pollution. However, it was not detected in low polluted samplessuch as seawater.

The restration on Cheong-Gye-Cheon is a project which was renovated from the high way where wasbusy by 17 thousands of traffics per day into a river with a rich nature. This paper considers on what the urbanstrategy in the restration project on the Cheong-Gye-Cheon is, seeing on the roots of the urban planning based onthe Feng-Shui, the construction of the project and the bus traffic reform.

Hachinohe National College of Technology (HNCT) and Gahanna Lincoln High School in Ohio, inthe USA have been having cultural exchange programs and a good relationship since 2007. Gahanna LincolnHigh School sent their students to HNCT in 2007, and HNCT has sent their students to Gahanna Lincoln HighSchool three times; 2008, 2011, and 2012. In this paper, significance of the oversea short program in the USA forthe younger students at National College of Technology was examined from the students' perspectives. Allparticipants believe their oversea short program is very significant for them. Not only they have come to knowthat they need communication skills in foreign languages but also they strongly think they have become moreopen-minded and have gained confidence, the ability to understand different cultures, and the flexibility to acceptfor different values, through the oversea short program. Moreover, they have come to think about their society,life, study, etc. from the other point of view.

In this global society, the students at National College of Technology are required to have not onlytechnical skills but also English communication skills and kokusairyoku, in other words, the ability to understanddifferent cultures, such as customs, traditions, religions, and cultural values, from different points of views. In thispaper, the kokusairyoku of the younger students at National Colleges of Technology is examined. Theseparticipants are those who have participated in the Short Overseas Study Program inMalaysia in 2011 or 2012. Thesame questionnaire was conducted in both years. Moreover, the questionnaire was conducted twice: before andafter each program, and all of the participants answered these questionnaires. The results show that the students'kokusairyoku have been improved after the Short Overseas Study Program inMalaysia.

Opinion of the lectures of general chemistry has been investigated for the second grade non-majorchemistry students of our college. It was found that most of the students thought the basic concepts of chemistrywere useful for their future career-path promotion, but they had frequently faced the problems of the difficulties inunderstanding the fundamental concepts of atomic and molecular structures during the lectures of generalchemistry.
