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 S₁ and S₂ 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 S₂ exhibited better photocatalytic activity than the photoanode S₁. In addition, photoanode S₂ had the lowest optical band-gap energy value (2.58 eV), which would allow better utilization of the solar spectrum.

WHO BENEFITS FROM IMPORT SUBSTITUTION INDUSTRIALIZATION (ISI) OF THE PHILIPPINE MILKFISH HATCHERY-BRED FRY INDUSTRY?

Yolanda T. Garcia,Maria Esperanza T. Garcia,Arnulfo G. Garcia 한국무역학회 2019 한국무역학회 국제학술대회 Vol.2019 No.08

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.

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.

Nuclear Suppliers Group and the Non-Proliferation Treaty : A Case Study of China and Indian Relations

Garcia, Ashley,Togle, Manuel 동덕여자대학교 한중미래연구소 2019 한중미래연구 Vol.12 No.-

인도는 수년 동안 핵 공급자집단(NSG)의 가입을 모색해 왔다. 배타적 그룹의 48개 회원 중 대부분이 인도를 지지했지만, 오직 한 국가, 중국만이 인도의 가입에 대한 거부권을 행사해왔다. 핵공급자집단은 만장일치에 기반한 집단이기 때문에 중국이 결정을 바꾸지 않는 이상 인도는 회원국의 자격을 갖출 수 없다. 그럼 중국은 왜 인도의 회원 가입을 거부하는 것일까? 주로 중국-파키스탄 관계와 인도-미국 관계에서 그 원인을 찾는 이전의 연구들과 달리 것과 달리 본 연구는 중국-인도 관계의 변화를 추적하는 것을 통해 그 원인을 찾고자 한다. India has been seeking membership into the Nuclear Suppliers Group (NSG) for years now. While most of the 48 members of the exclusive group has vouched for India, one country in particular is vetoing this and that country is China. Because NSG is a consensus-based group, India cannot be given membership if China does not concede to their decision. Why China is vetoing India’s membership bid so much. This paper aims to view different possible reasons why this is the case, mostly focusing on China-India relations, alongside the dynamics of China-Pakistan and India-United States relations.

Fatigue experiments on steel cold-formed panels under a dynamic load protocol

Garcia-Palencia, Antonio J.,Godoy, Luis A. Techno-Press 2013 Structural Engineering and Mechanics, An Int'l Jou Vol.46 No.3

A dynamic load protocol has been used to experimentally simulate fatigue behavior in cold-formed metal panels with screwed connections under wind loading. The specific protocol adopted is an adaptation of SIDGERS, originally developed for non-metallic membranes, which is composed of levels each under increasing load values. A total of 19 tests were performed on 3.35 m long by 0.91 m wide panels, identified as Type B-wide rib and Type E, both with screw connections at the edge and at the center, thus conforming two-span specimens. In some configurations the panels were fixed at the valleys, whereas crest-fixed connections were also investigated. Reinforcing the connections by means of washers was also investigated to evaluate their efficiency in improving fatigue capacity. The experimental results show maximum load capacities in improved connections with washers of approximately twice of those with classical connections.

Garcia Paula Pontes,Cappoani Aline,Schelbauer Ricardo Susin,Correr Gisele Maria,Gonzaga Carla Castiglia 대한치과보존학회 2020 Restorative Dentistry & Endodontics Vol.45 No.4

Objectives: The aim of this study was to perform a clinical and radiographic analysis of endodontically treated teeth (ETT) restored with cast metal posts (CMPs) or prefabricated glass fiber posts (GFPs) and crowns. Materials and Methods: Fifty ETT were restored with 25 CMPs and 25 GFPs at a private dental clinic between 2001 and 2016. The restorations consisted of 12 all-ceramic crowns, 31 metal-ceramic crowns, and 7 composite resin crowns. Demographic data, type of teeth, type of post-and-core system, time of placement, crown restorations, the number of proximal contacts, the type of antagonist, and reports of any complications after post-and-core placement were recorded for each patient. Assessments were performed at baseline (radiographic) and follow-up (radiographic and clinical). Data were analyzed by the McNemar test, the Pearson χ2 test, and Kaplan-Meier survival curves (α = 0.05). The mean follow-up was 67.6 months. Results: No significant difference was observed for any of the radiographic parameters when the baseline and final radiographs were compared. In the clinical evaluation, anatomical form (p = 0.009) and occlusion (p = 0.001) showed significant differences according to the type of crown restoration; specifically, metal-ceramic and all-ceramic crowns outperformed composite resin crowns. Conclusions: CMPs and GFPs showed favorable results for restoring ETT after 6 years of follow-up. All-ceramic and metal-ceramic crowns showed higher survival rates and better clinical outcomes.

ISOMETRIC REFLECTIONS IN TWO DIMENSIONS AND DUAL L¹-STRUCTURES

Garcia-Pacheco, Francisco J. Korean Mathematical Society 2012 대한수학회보 Vol.49 No.6

In this manuscript we solve in the positive a question informally proposed by Enflo on the measure of the set of isometric reflection vectors in non-Hilbert 2-dimensional real Banach spaces. We also reformulate equivalently the separable quotient problem in terms of isometric reflection vectors. Finally, we give a new and easy example of a real Banach space whose dual has a non-trivial L-summand that does not come from an M-ideal in the predual.
