The electrochemical properties of bare and Co 3 (PO 4 ) 2 -coated LiNi 0.8 Co 0.16 Al 0.04 O 2 electrodes after high current damage testing were characterized. Damage was induced by cycling with a high current density of 600 m Ag -1 . Co 3 (PO 4 ) 2 -coated LiNi 0.8 Co 0.16 Al 0.04 O 2 electrodes exhibit lower capacity loss and better charge retention than bare LiNi 0.8 Co 0.16 Al 0.04 O 2 electrodes after damage testing. The discharge capacity reduction of bare and Co 3 (PO 4 ) 2 -coated electrodes after damage testing were *27 and 15%, respectively. The impedance of cells containing bare electrodes remarkably increased after high current cycling, which may be induced by damage to the electrode surface. However, damage was successfully suppressed by the Co 3 (PO 4 ) 2 coating. Bare LiNi 0.8 Co 0.16 Al 0.04 O 2 electrodes developed large amounts of cracks and other extended defects after high current cycling. In contrast, Co 3 (PO 4 ) 2 -coated electrodes maintained stable features after high current cycling, indicating the coating layer effectively protected the surface of the LiNi 0.8-Co 0.16 Al 0.04 O 2 powder.

Microencapsulation of insulin has been difficult, due to the high sensitivity of insulin to the harsh conditions that can occur during the microencapsulation process. We have developed a method of preparing insulin-loaded microcapsules by using a monoaxial ultrasonic atomizer to form microdroplets of insulin in aqueous solution surrounded by poly(lactic-co-glycolic acid) (PLGA) solution. Administration of these insulin-loaded microcapsules to type 1 diabetic rats maintained plasma insulin concentrations for 30 days, due to the sustained insulin release properties of the microcapsules. In contrast, plasma insulin concentrations after subcutaneous injection of insulin solution reached near zero levels within 2 days. Insulin solution showed only an immediate pharmacological effect, with no reduction of glycemia after 3 days, whereas insulin-loaded microcapsules maintained blood glucose levels at 100-200 mg/dL for 55 days. Molecular imaging using fluorescein isothiocyanate (FITC)-insulin-loaded microcapsules showed in vivo sustained release of the FITC-insulin in microcapsules. Using insulin-loaded microcapsules, we observed inflammation only immediately after injection, indicating that the rats adapted to long-term insulin release. In conclusion, insulin-loaded microcapsules may reduce nonrepetitive insulin administration and show sustained pharmacological performance.

We examine the electroforming-dependent multifunctional resistive switching features by operating a merged Pt/Ta2O5−x/Ta–Ta/Ta2O5−x/Pt switching device under particular bias and polarity conditions.

Due to the improvement of high technology and the excessive congestion of cities, the number of high rise buildings has been increasing gradually. Also the number of studies about this issue has been rising relatively. However the previous research on super high rise buildings focused mostly on the use of public space from building plan perspective, survey ‘of residents’ satisfaction evaluation, construction technology and structural technology. Little research is done on the economic analysis of landmark factors. The purpose of this study is to find landmark factors that can be quantitatively measured, collect data on super high rise residential buildings in Seoul. Find the intrinsic values of the landmarks, and analyze how these values differ in areas with different densities, i.e. in Gangnam‐area and Yeongdeungpo‐gu and in other areas. It is expected that the results of this study can be used to set an appropriate price of super high rise building in consideration of its landmark value in different area. Santruka Del aukštuju technologiju tobulejimo ir pernelyg dideles miestu perkrovos ypač padaugejo aukštybiniu pastatu. Taip pat santykinai padidejo su šiuo klausimu susijusiu studiju. Tačiau atliekant ankstesnius ypač aukštu pastatu tyrimus daug demesio skirta viešosios erdves išnaudojimui pastato suplanavimo požiūriu, gyventoju pasitenkinimo tyrimo vertinimu, statybos ir struktūrinemis technologijomis. Mažai tyrimu atlikta analizuojant ekonominius žemes naudojimo veiksnius. Šio tyrimo tikslas ‐ išsiaiškinti kiekybiškai išmatuojamus žemes naudojimo veiksnius, rinkti duomenis apie ypač aukštus gyvenamuju namu pastatus Seule, rasti šiems pastatams būdingu vertybiu orientyrus ir analizuoti, kaip šie dydžiai skiriasi pagal skirtingo apgyvendinimo tankio teritorijas, t. y. Gamgnam, Yeongdeungpo‐gu ir kitose vietose. Tikimasi, kad šio tyrimo rezultatai gali būti naudojami nustatant tinkama ypač aukštu pastatu kaina, atsižvelgiant i žemes naudojimo verte skirtingose vietovese.
