Presence Architecture for RFID-based Supply Chain
최선완,김은숙,강신각,J.J. Garcia-Luna-Aceves 안양대학교 산업기술연구소 2004 自然科學硏究 Vol.11 No.1
RFID-based supply chain is performed by using RFID tags and readers to pass RFID tag numbers, and then leveraging the Internet to access large amount of associated information that can be shared among authorized users [6]. The information is for physical objects such as foods, items, goods, equipments, or transportations. They move through supply chain such as manufactures, distributors, and retailers. The movement incurs the change of location (spatial and/or temporal) and ownership. The status of change should be notified to information recipients. This paper defines presence architecture for the RFID-based supply chain. This paper adopts the previous work of the IETF GEOPRIV WG, which applies mobile devices, such as GPS device and cell phone, to a present architecture for the distribution of location objects by examining the existing IETF works [2,3].
Comparative Study of Undoped and Nickel-Doped Molybdenum Oxide Photoanodes for PEC Water Splitting
Garcia-Garcia, Matias The Korean Electrochemical Society 2022 Journal of electrochemical science and technology Vol.13 No.3
The current global energy supply depends heavily on fossil fuels. This makes technology such as direct water splitting from harvesting solar energy in photoelectrochemical (PEC) systems potentially attractive due to its a promising route for environmentally benign hydrogen production. In this study, undoped and nickel-doped molybdenum oxide photoanodes (called photoanodes S<sub>1</sub> and S<sub>2</sub> respectively) were synthesized through electrodeposition by applying -1.377 V vs Ag/AgCl (3 M KCl) for 3 hours on an FTO-coated glass substrate immersed in molibdatecitrate aqueous solutions at pH 9. Scanning electron microscopy (SEM), atomic force microscopy (AFM), energy-dispersive X-ray spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS) were used for microstructural and compositional characterizations of the photoanodes. In addition, the optical and photoelectrochemical characterizations of these photoanodes were performed by UV-Visible spectroscopy, and linear scanning voltammetry (LSV) respectively. The results showed that all the photoanodes produced exhibit conductivity and catalytic properties that make them attractive for water splitting application in a photoelectrochemical cell. In this context, the photoanode S<sub>2</sub> exhibited better photocatalytic activity than the photoanode S<sub>1</sub>. In addition, photoanode S<sub>2</sub> had the lowest optical band-gap energy value (2.58 eV), which would allow better utilization of the solar spectrum.
Market Integration through Smuggling: China's Sanction on Norwegian Salmon
Roberto J. Garcia(Roberto J. Garcia ),Thi Ngan Giang Nguyen(Thi Ngan Giang Nguyen ) 세종대학교 경제통합연구소 2023 Journal of Economic Integration Vol.38 No.1
Popular press accounts and the political-economics literature link awarding the 2010 Nobel Peace Prize to a Chinese dissident to China's trade sanction on Norway's whole, fresh/chilled salmon exports. Norway lost its dominant supplier share of the Chinese market as its total salmon exports to China decreased. Then, in 2011, Vietnam dramatically increased its imports of Norwegian salmon. A structural break divides the data series into two sub-periods: July 1997 to February 2011, and March 2011 to December 2018 (the sanction period). This provides statistical evidence of China imposing an unannounced trade sanction. During the sanction period, Vietnam's current monthly imports are negatively affected by China's lagged monthly imports. A decrease in China's previous monthly salmon imports from Norway “Granger causes” an increase in Vietnam's current imports. No such relationship existed before the sanction, implying that China and Vietnam's salmon markets became integrated through smuggling.

This study aims to estimate the welfare gains of the Philippine milkfish industry in establishing local fry hatcheries to reduce imports from Indonesia and Taiwan. It also seeks to establish the industry stakeholders who gain from this import substitution industrialization (ISI). The economic surplus model was used to estimate the welfare gains from ISI of hatchery-bred milkfish fry in the fishery sector. Specifically, the changes in consumer and/or producer surplus per stakeholder were compared to determine who the biggest gainers are. Results of the study showed that the consumer surplus from the milkfish fry industry was larger than its producer surplus. On the other hand, the reverse was true for the grow-out industry. It is interesting to note that the consumers in the fry industry and the producer in the grow-out industry were the same set of stakeholders, i.e., the milkfish grow-out operators, who gained the most from the ISI of the hatchery-bred fry. The study also showed that the commercialization of the local milkfish hatchery technologies can bring about more benefits to the country than importing frys and fingerlings. Hence, ISI of local hatcheries for other aquaculture species can be expected to bring similar welfare gains. More importantly, the technical and financial assistance that were extended by the government’s fishery sector through the GAINEX project as pioneered by DOST-PCAARRD can serve as an effective catalysts to prospective hatchery operators in reducing the risks, especially when setting-up a new enterprise like the hatchery-bred fry for an emerging aquaculture species in the country.

PURPOSE. In this study, a temporal abutment fixation screw, designed to fracture in a controlled way upon application of an occlusal force sufficient to produce critical micromotion was developed. The purpose of the screw was to protect the osseointegration of immediate loaded single implants. MATERIALS AND METHODS. Seven different screw prototypes were examined by fixing titanium abutments to 112 Mozo-Grau external hexagon implants (MG Osseous$^{(R)}$; Mozo-Grau, S.A., Valladolid, Spain). Fracture strength was tested at $30^{\circ}$ in two subgroups per screw: one under dynamic loading and the other without prior dynamic loading. Dynamic loading was performed in a single-axis chewing simulator using 150,000 load cycles at 50 N. After normal distribution of obtained data was verified by Kolmogorov-Smirnov test, fracture resistance between samples submitted and not submitted to dynamic loading was compared by the use of Student's t-test. Comparison of fracture resistance among different screw designs was performed by the use of one-way analysis of variance. Confidence interval was set at 95%. RESULTS. Fractures occurred in all screws, allowing easy retrieval. Screw Prototypes 2, 5 and 6 failed during dynamic loading and exhibited statistically significant differences from the other prototypes. CONCLUSION. Prototypes 2, 5 and 6 may offer a useful protective mechanism during occlusal overload in immediate loaded implants.

This work deals with the validation of a high-fidelity multiphysics system coupling the Serpent 2 Monte Carlo neutron transport code with SUBCHANFLOW, a subchannel thermalhydraulics code, and TRANSURANUS, a fuel-performance analysis code. The results for a full-core pin-by-pin burnup calculation for the ninth operating cycle of the Temelín II VVER-1000 plant, which starts from a fresh core, are presented and assessed using experimental data. A good agreement is found comparing the critical boron concentration and a set of pin-level neutron flux profiles against measurements. In addition, the calculated axial and radial power distributions match closely the values reported by the core monitoring system. To demonstrate the modeling capabilities of the three-code coupling, pin-level neutronic, thermalhydraulic and thermomechanic results are shown as well. These studies are encompassed in the final phase of the EU Horizon 2020 McSAFE project, during which the Serpent-SUBCHANFLOW-TRANSURANUS system was developed.

<B>ABSTRACT</B><P>The saimiri transforming protein oncogene, called STP-A, of herpesvirus saimiri (HVS) subgroup A is not required for viral replication but is required for lymphoid cell immortalization in culture and lymphoma induction in primates. Here we report that STP-A interacts with cellular tumor necrosis factor receptor-associated factors (TRAF2 and TRAF6) and Src family protein tyrosine kinases (SF-PTKs) in a genetically and functionally separable manner and that each interaction constitutively elicits independent cellular signal transduction. The amino-terminal and central proline-rich motifs of STP-A were responsible for TRAF6 and TRAF2 interactions, respectively, and STP-A and TRAF6 interaction contributed to the majority of NF-κB activation, whereas STP-A and TRAF2 interaction played a minor role in NF-κB activation. On the other hand, interaction of STP-A with SF-PTKs through its SH2 binding motif effectively elicited AP-1 and NF-AT transcription factor activity. One cellular gene targeted by STP-A is intercellular adhesion molecule 1 (ICAM-1), which participates in a wide range of inflammatory and immune responses. Both TRAF and SF-PTK signal transductions induced by STP-A were required for the marked increase of ICAM-1 expression. These results demonstrate that the viral oncogene STP-A independently targets two vital cellular signaling molecules and that these activities likely contribute to HVS-mediated lymphoid cell immortalization in culture and lymphoma induction in primates.</P>
