        Introduction to "Binding Maritime China: Control, Evasion, and Interloping"

        Eugenio Menegon 고려대학교 민족문화연구원 2017 Cross-Currents Vol.0 No.25

        Maritime Asia is a confusing morass of contested sovereignties and geopolitical rivalries. Yet the seaways of Asia have, in their history, also fostered cultural exchange and economic integration. The liminal maritime zone surrounding China remains a paradox between seas and ports teeming with legal and illegal exchange and governmental policies attempting to monopolize and restrict that exchange. Vast and fluid, maritime China has long hindered state control and fostered connections determined as much by bottom-up economic and cultural logic as by top-down official impositions. This issue of Cross-Currents proposes to reexamine the rich history of maritime China and adjacent areas by tracing the interactions of the three initiatives of control, evasion, and interloping. This special issue stems from a conference the guest editors organized in Boston in 2015, with support from Boston University, Brandeis University, Northeastern University, and the Taiwan Ministry of Education. We invited a distinguished group of scholars to explore the many facets of maritime China’s history. Our key postulation was that state control, evasion from that control, and interloping within the interstices of China’s maritime world literally bound an array of actors and locales for distinct but interrelated goals, from the early modern era to the modern era. This concept is encapsulated in the title of the current issue, “Binding Maritime China.” What “creates” and gives coherence to the concept of maritime China as a social, economic, political, and geographic space is, to a large extent, how human actors (Chinese and Western merchants and businessmen, navy officers, bureaucrats, fishermen, pirates, missionaries, and so on) productively interacted or experienced conflicts and resisted one another’s control. They did so across oceanic and coastal spaces, administrative boundaries, class lines, bureaucratic institutions, commercial organizations, and competing imperial formations...

        Interlopers at the Fringes of Empire: The Procurators of the Propaganda Fide Papal Congregation in Canton and Macao, 1700-1823

        Eugenio Menegon 고려대학교 민족문화연구원 2017 Cross-Currents Vol.0 No.25

        The office of the procurator of the papal Sacred Congregation for the Propagation of the Faith (Sacra Congregatio de Propaganda Fide) offers a unique case study of noncommercial interloping in the long eighteenth century in the Pearl River Delta, and reveals the complexity and fluidity of life at the intersection of Asian and European maritime environments in that special human ecosystem. The oceanic infrastructure of the Age of Sail and the Sino-Western trade system in Canton sustained the Catholic missionary enterprise in Asia, and the professional figure of the procurator represented its economic and political linchpin. Procurators were agents connected with both European and Qing imperial formations, yet not directly at their service. They utilized existing maritime trade networks to their own advantage without being integral parts of those networks’ economic mechanisms. All the while, they subverted Qing prohibitions against Christianity. Using sources preserved in Rome, this article offers new insights into the global mechanisms of trade, communication, and religious exchange embodied by the procurators-interlopers and their networks, with significant implications for the history of the Sino-Western trade system, Qing policies toward the West and Christianity, and the history of Asian Catholic missions.

        A Method to Estimate Occupational Health and Safety Costs in Construction Projects

        Eugenio Pellicer,Gloria I. Carvajal,M. Carmen Rubio,Joaquín Catalá 대한토목학회 2014 KSCE JOURNAL OF CIVIL ENGINEERING Vol.18 No.7

        This paper presents the results of a research project carried out in Spain that aims to develop a method that let employers to assess, during the design phase, the occupational health and safety costs of a specific construction project. This method classifies costs in four categories: insurance costs, prevention costs, accident costs, and recovery of costs. Labor accident data were obtained from 1990 to 2007 for the entire Spanish construction industry, and these data were subsequently homogenized and exploited. A mathematical model was created for computing each cost category. This method allows employers and project managers to estimate aprioristically the cost incurred as a result of occupational health and safety during the project, based on tangible values such as the construction project budget or the work schedule, as well as statistical data. An application to this method in a case study illustrated that the occupational health and safety costs for that construction project came to approximately 5% of the total cost of the budget.

        BlockHealth: Blockchain-based Secure and Peer-to-peerHealth Information Sharing with Data Protection and Right to be Forgotten

        Eugenio Balistri,Francesco Casellato,Carlo Giannelli,Cesare Stefanelli 한국통신학회 2021 ICT Express Vol.7 No.3

        To identify health risks in working environments, it is crucial for companies to share personal health data demonstrating to clients and suppliers their employees are healthy, while being compliant with data protection legislation. Based on these considerations, our Blockchain-based BlockHealth solution allows personal health data sharing with tamper proofing and data protection. Traditionally, the Blockchain guarantees data immutability but not confidentiality. On the contrary, BlockHealth stores in the Blockchain only hash values of data. Health data is stored in private databases managed by companies, thus also allowing to delete data in compliance with the right to be forgotten.

        LCF/TMF MODEL BASED APPROACH FOR THE PREDICTION OF FATIGUE LIFE OF COMPONENTS IN LIGHTWEIGHT AUTOMOTIVE ENGINES

        Eugenio Brusa,Enrico Ossola,Raffaele Bonavolontà,Andrea Mazzetto 한국자동차공학회 2020 International journal of automotive technology Vol.21 No.2

        The life prediction of mechanical components in presence of Thermo-Mechanical Fatigue (TMF) is a crucial issue of the design activity. In the combustion engine, that action looks rather difficult because of a superposition of several damage phenomena. Some TMF models are currently available in the literature, but they include many parameters, whose calibration usually requires an onerous testing activity. Therefore, industry requires an assessment of those techniques, to be implemented through some simplified and reliable procedures. In this paper, the prediction of TMF life of a lightweight engine component is based on a new procedure, exploiting the isothermal Low-Cycle Fatigue (LCF) and creep tests, some theoretical approaches applied to TMF and numerical modeling. The A356 Aluminum Alloy is analyzed, as an example of strategic material used to design the new automotive lightweight engines. The calibration of TMF models based on the isothermal LCF and creep tests was found reliable. The fatigue life prediction looks compatible with some preliminary experimental results. Therefore, the proposed approach is suitable to simplify the design procedure, to decrease costs, especially related to testing, and to perform a preliminary trade-off activity of the engine layout.

        Cyclic fatigue resistance, torsional resistance, and metallurgical characteristics of M3 Rotary and M3 Pro Gold NiTi files

        Eugenio Pedullà,Fabio Lo Savio,Giusy Rita Maria La Rosa,Gabriele Miccoli,Elena Bruno,Silvia Rapisarda,장석우,Ernesto Rapisarda,Guido La Rosa,Gianluca Gambarini,Luca Testarelli 대한치과보존학회 2018 Restorative Dentistry & Endodontics Vol.43 No.2

        Objectives To evaluate the mechanical properties and metallurgical characteristics of the M3 Rotary and M3 Pro Gold files (United Dental). Materials and Methods One hundred and sixty new M3 Rotary and M3 Pro Gold files (sizes 20/0.04 and 25/0.04) were used. Torque and angle of rotation at failure (n = 20) were measured according to ISO 3630-1. Cyclic fatigue resistance was tested by measuring the number of cycles to failure in an artificial stainless steel canal (60° angle of curvature and a 5-mm radius). The metallurgical characteristics were investigated by differential scanning calorimetry. Data were analyzed using analysis of variance and the Student-Newman-Keuls test. Results Comparing the same size of the 2 different instruments, cyclic fatigue resistance was significantly higher in the M3 Pro Gold files than in the M3 Rotary files (p < 0.001). No significant difference was observed between the files in the maximum torque load, while a significantly higher angular rotation to fracture was observed for M3 Pro Gold (p < 0.05). In the DSC analysis, the M3 Pro Gold files showed one prominent peak on the heating curve and 2 prominent peaks on the cooling curve. In contrast, the M3 Rotary files showed 1 small peak on the heating curve and 1 small peak on the cooling curve. Conclusions The M3 Pro Gold files showed greater flexibility and angular rotation than the M3 Rotary files, without decrement of their torque resistance. The superior flexibility of M3 Pro Gold files can be attributed to their martensite phase.
