在國際貿易活動，買賣雙方可能因為互不信任，買方擔心預先支付款項後，賣方不按交易合同要求出貨；賣方也擔心在出貨或提交貨運單據後買方不依約付款。因此需要兩家銀行作為買賣雙方的保證人，幫忙代為收款交單，以銀行的信用代替商業信用，銀行在這一方面的活動中所使用的工具就是信用狀(Letter of Credit，L/C)。 區塊鏈(Blockchain)，是一個分散式的帳本系統，採用密碼學技術來確保交易的正確性，公開、公正、透明及無法竄改特性，經濟學人稱之為信任機器(Trust Machine)。 本研究所採用的區塊鏈信用狀系統，應用區塊鏈加快‪國際貿易信用狀處理流程，則是利用區塊鏈(Blockchain)技術特性，建立一個區塊鏈交易應用平台，協助解決國際貿易時，各方參與角色的信任問題，達到傳統銀行的信用狀功能，使其中間交易支付過程可不需透過銀行，如此便可降低了銀行風險，以及降低貿易上的費用及縮短交易支付時間，根本上解決了貿易上最重要的信任問題，達到國際貿易的目的。 / In the case of international trade activities, buyers and sellers may be mistrustful and the buyer is worried that the seller will not be required to ship the goods after the advance payment; the seller is also concerned that the buyer will not pay the contract after the shipment or delivery of the shipping documents. So the two banks as the guarantor of buyers and sellers, to help on behalf of the payment of orders to the bank's credit instead of commercial credit, the bank in this area activities used in the tool is the letter of credit (Letter of Credit, L/C) The Blockchain is a decentralized ledger system that uses cryptography to ensure the correctness, openness, fairness, transparency and tampering of transactions. Economists call it Trust Machine. The blockchain trust system used in this research, the application of blockchain to speed up the international trade credit processing process, it is the use of blockchain technology characteristics, the establishment of a blockchain trading application platform to help solve international trade , The parties involved in the role of the trust of the problem, to the traditional bank's L/C function, so that the process of intermediate transactions can not be through the bank, so that can reduce the bank risk, as well as reduce trade costs and shorten the transaction payment time. It is easy to solve the most important issues of trust. To achieve the purpose of international trade.

Ensaio sobre as metamorfoses e a centralidade do mundo do trabalho e Os sentidos do trabalho: ensaio sobre a afirmação e a negação do trabalho, com o intuito de constatar a contribuição dessas obras para o Serviço Social. Para tanto, inicialmente fez-se uma incursão preliminar a partir dos trabalhos publicados nos eventos mais relevantes do Serviço Social brasileiro: CBAS (2007 e 2010) e ENPESS (2008 e 2010), tendo como critério, os trabalhos fundamentados nas duas obras supracitadas, com o intuito de verificar como os assistentes sociais têm se apropriado da discussão complexa sobre a categoria trabalho, sobretudo sua centralidade, questionando a potência revolucionária da classe trabalhadora. Num segundo momento, fizemos pesquisa empírica, com entrevista semiestruturada com o profº Dr. Ricardo Antunes, com vistas a esclarecer criticamente as questões constatadas na apropriação de suas obras e contribuir com o relevante debate sobre a categoria trabalho no Serviço Social. Os resultados das pesquisas realizadas evidenciaram a relevância das obras do profº Ricardo Antunes para o Serviço Social, constituindo-se um marco histórico no debate sobre a centralidade da categoria trabalho na sociedade contemporânea. Por fim, espera-se com essa tese de doutorado, contribuir com a produção de conhecimentos para o Serviço Social (e áreas afins), a partir desta discussão teórica relevante e pertinente atualmente à categoria, com vistas a responder à visão endógena e reducionista que persiste no Serviço Social. Pretende-se, ainda, evidenciar a importância das referidas obras de... / This Doctoral Thesis, defended at the Graduate Program in Social Work from the State University - UNESP-Franca/SP, aimed to discuss and reflect on the appropriation of Ricardo Antunes’s studies by the Brazilian Social Work, prioritizing its two classics: Goodbye to work? Essay on the metamorphosis and the centrality of the working world and The meanings of work: essay on the affirmation and negation of work, in order to observe the contribution of these works for Social Work. For this purpose, initially made up a preliminary foray from papers published in the most important events of the brazilian Social Work: CBAS (2007 and 2010) and ENPESS (2008 and 2010), taking as a criterion, the works based on the two aforementioned works, in order to verify how social workers have appropriated the complex discussion about the working class, especially its centrality, questioning the revolutionary power of the working class. Secondly, we made an empirical research with semi-structured interview with Ricardo Antunes, with a view to critically clarify the issues noted in the appropriation of his work and thus, contribute to the important debate about the work in the Social Work category. The results showed the relevance of the works of Ricardo Antunes for Social Work, becoming a landmark in the debate on the centrality of the work category in contemporary society. Finally, it is expected that this thesis contribute to the production of knowledge in social work (and related fields), from this theoretical discussion relevant and pertinent to the current category, in order to respond to the endogenous and reductionist vision which persists in Social Work. It is intended also to highlight the importance of the works of Ricardo Antunes as a watershed in the social sciences and humanities, emphasizing the real possibility of human emancipation enunciated by Karl Marx in the nineteenth century / Esta tesis doctoral, defendida en el Programa de Posgrado en Trabajo Social de la Universidad del Estado de São Paulo - UNESP-Franca/SP, tuvo como objetivo debatir y reflejar sobre la apropiación de las obras de Ricardo Antunes por el Trabajo Social brasileño dando prioridad a sus dos clásicos: Adiós al trabajo? Ensayo sobre la metamorfosis y la centralidad del mundo del trabajo y Los sentidos del trabajo: ensayo sobre la afirmación y la negación del trabajo, con el fin de observar la contribución de estas obras para el Trabajo Social. Para ello, inicialmente compuesto por una incursión preliminar de los trabajos publicados en los eventos más importantes del Trabajo Social brasileño: CBAS (2007 y 2010) y ENPESS (2008 y 2010), tomando como criterio, los trabajos basados en las dos obras mencionadas, con el fin de verificar cómo los trabajadores sociales se han apropiado de la compleja discusión sobre la clase obrera, sobre su centralidad, cuestionando el poder revolucionario de la clase obrera. En segundo lugar, hemos hecho una investigación empírica a través de entrevista semi-estructurada con el profesor Dr. Ricardo Antunes, con el fin de aclarar críticamente las cuestiones señaladas en la apropiación de su trabajo y contribuir al debate importante sobre el trabajo en la categoría de los trabajadores sociales. Los resultados de las investigaciones realizadas demostraron la relevancia de las obras del profesor Ricardo Antunes para el Trabajo Social, constituyéndose en un punto de referencia en el debate sobre la centralidad de la categoria trabajo en la sociedad contemporánea. Por último, se espera que esta tesis contribuya a la producción de conocimiento para el Trabajo Social (y afines), a partir de esta discusión teórica relevante y pertinente para la categoría actual, con el fin de contestar la visión endógena y reduccionista que persiste en el Trabajo Social...

The presented thesis deals with the design and assembly of the generator for pulse magnetron sputtering. The designed device is capable of generating two square wave signals via its counter-working outputs. Both signals have independently adjustable frequency, pulse count and duty ratio. Both signals originate from two frequency syntheses controlled by microcontroller PIC16F877A. All the settings are entered by four buttons and are shown on an alphanumeric display with 16x4 characters. The duty ratio is adjusted using a special module.
