Sistemas auxiliares de desinfeção em Endodontia

Introdução: O objetivo da terapia endodôntica é eliminar a infeção presente nos canais radiculares e prevenir a reinfeção dos mesmos, criando assim as condições para a manutenção da peça dentária em função e livre de patologia pulpar ou peri-apical. A complexa anatomia dos canais faz com que seja impossível uma limpeza completa dos mesmos. Para se conseguir um bom resultado clínico é de extrema importância utilizarmos técnicas e procedimentos que visem uma utilização combinada de instrumentação mecânica e desinfeção com soluções de irrigação. Objetivo: Revisão bibliográfica sobre sistemas auxiliares de desinfeção em Endodontia, abordando as suas principais vantagens e limitações e apresentando estudos que provam a sua importância para o sucesso do tratamento endodôntico. Materiais e métodos: Realizou-se uma pesquisa eletrónica nos principais motores de busca online tais como PubMed, B-On, Scielo e Science Direct e em livros científicos sobre a temática, utilizando palavras-chave em inglês tais como “irrigation techniques”, “sonic irrigation”, “EndoVac”, “EDTA”, “hypoclorite sodium”, “passive ultrasonic irrigation”, “apical negative pressure irrigation”, “root canal irrigation”, “EndoAtivator”, e ainda alguns termos em português tais como “insucesso em endodontia”, “hipoclorito de sódio” “ácido cítrico” e “irrigação sónica e ultrasónica”. Da pesquisa efectuada entre Junho e Novembro de 2015 e cujo critério de inclusão foram artigos datados de 2001 a 2015, escolheu-se 65 artigos em inglês, 4 em português e 1 em espanhol, dos quais se utilizaram 44 artigos. Além dos artigos analisou-se 2 livros, dos quais se utilizou 1. Resultados: Os artigos analisados apresentam como principais resultados que a combinação de instrumentação mecânica e a irrigação reduz mas não elimina totalmente as bactérias. Até à data não existem soluções de irrigação ideais. Têm-se desenvolvido técnicas capazes de combater as dificuldades encontradas e aumentar as potencialidades da irrigação, cada uma apresentando suas vantagens e desvantagens. Dos resultados constatados, a literatura científica aparenta reconhecer o Sistema EndoVac como o melhor em termos de biossegurança e o sistema de irrigação ultrasónica passiva como o melhor em termos de desinfecção e limpeza. Conclusão: Uma combinação de soluções com uma sequência específica é aparentemente necessária para atingir o sucesso endodôntico, bem como uma escolha adequada da técnica. As novas técnicas desenvolvidas tais como a ativação dinâmica manual, irrigação ultrasónica passiva, ativação sónica e sistemas de pressão apical negativa apresentam melhores resultados quando associados a irrigantes adequados como o hipoclorito, EDTA, ácido cítrico, clorohexidina e álcool. No entanto, concluiu-se que mais investigação é necessária para melhorar o sucesso do tratamento endodôntico não-cirúrgico.

The Effects of World War II on Significant Composers of Music for the Flute

World War II was one of the most devastating events in history, and it profoundly affected European culture and art. I examined the period around World War II, and the effects it had on the lives of composers and their flute music. I investigated who wrote for flute during the war, what they were composing, and what effects, if any, the war had on them and their music. After examining the biographies of nine composers and studying eleven of their works, I found that in some cases the war affected their flute music, but in others the music shows no apparent influences of the war. Interestingly, most of the flute music written by composers affected by World War II was happy and joyful rather than dark and dismal. I performed three recitals during my research. I studied nine composers and performed some of their most important works for flute. Recital One is “Sonatas for Flute.” Recital Two is “Virtuosic Flute Music,” and my final recital is “Emotional Overview of Flute Music During World War II.” I discovered that many of these composers had to change their lives in drastic ways due to the war, but most them wrote music that had did not reflect the horror or destruction of war—perhaps music represented an escape from their horrible circumstances, or an effort to recall better times. I also found that a few of these composers used music to mock the Nazi regime. They used music as an emotional outlet, which could have been dangerous for them during that time. Other composers used music to share their own personal experiences while fighting in the war.

Processus d’adaptation des personnes vivant avec la schizophrénie et ayant un soutien social limité

Résumé : La schizophrénie est un trouble mental grave qui affecte toutes les facettes de la vie de la personne. En outre, le manque de soutien social est un problème important qui contribue à l’aggravation de la maladie, notamment en influençant négativement la capacité d’adaptation. Chez les personnes atteintes de schizophrénie, la capacité à utiliser des stratégies d’adaptation adéquates et efficaces est essentielle afin d’améliorer la santé, le bien-être et la prévention des rechutes. Cette recherche utilise la conception de l’adaptation de Roy (2009). De nombreuses études confirment la présence de difficultés d’adaptation chez ces personnes. De plus, le processus d’adaptation lui-même reste mal connu. La question de recherche était : Quel est le processus d’adaptation des personnes vivant avec la schizophrénie lorsque leur soutien social est limité ? Cette question sous-tendait deux objectifs : 1) décrire le processus d’adaptation des personnes atteintes de schizophrénie dans un contexte de soutien social limité et 2) contribuer au développement du modèle de Roy dans le contexte des troubles mentaux graves. Le devis de recherche était la théorisation ancrée constructiviste, auprès de 30 personnes vivant avec la schizophrénie. Les données étaient composées d’entrevues et de résultats de trois questionnaires qui ont contribué à décrire de façon plus détaillée le profil des participants. Les résultats sont une modélisation du processus d’adaptation nommée « les filtres dans le processus d’adaptation des personnes vivant avec la schizophrénie ». Cette modélisation met en lumière le fait que le potentiel d’adaptation des personnes vivant avec la schizophrénie est affecté à la fois par des éléments de l’environnement social et des éléments inhérents à la maladie elle-même. Ces éléments altèrent la possibilité et la capacité à utiliser des stratégies d’adaptation adéquates et efficaces. Ces résultats de recherche pourraient permettre d’améliorer l’évaluation des personnes atteintes de schizophrénie et de diminuer les « inconnues » dans l’effet des interventions, tout comme de favoriser les actions visant à lutter contre les conditions sociales qui nuisent à l’adaptation.

É preciso ter coragem: um estudo das narrativas de mulheres na política

É na busca por compreender a inserção e participação de mulheres na política partidária na contemporaneidade que esta dissertação, situada na linha de pesquisa Culturas, Linguagens e Utopias, tem como objetivo analisar as narrativas de vereadoras de municípios que estão localizados na região sul do Rio Grande do Sul no período de 2009-2012. O corpus de análise constitui-se de entrevistas individuais semiestruturadas com as onze vereadoras participantes a partir da metodologia de investigação narrativa. Partindo das contribuições dos Estudos Culturais e de Gênero em suas vertentes pós-estruturalistas procurou-se problematizar alguns discursos e práticas que emergiram nas narrativas com base nas contribuições da análise do discurso de Michel Foucault. Assim, verificou-se que a representação cultural das mulheres neste campo político está fundamentada em concepções essencialistas do gênero feminino como a sensibilidade. Isso vem provocando discussões na ciência política e nos estudos de gênero a partir de termos como política de ideias, política de desvelo que discutem a presença das mulheres em decorrência ou não desses atributos. O fato é que esses discursos vêm instituindo diferenças na participação de homens e mulheres na política e constituindo formas de ser mulher na política partidária e de fazer política diferenciada das dos homens de forma menos “dura”, “rígida”. Ao debruçar-se na inserção das mulheres nessa esfera pública constatou-se uma trajetória marcada pelas noções de público e privado que impediu ao longo de nossa história a participação das mulheres no campo político e o desenvolvimento de sua cidadania. Além disso, nas narrativas das vereadoras fica evidente que as mulheres não foram constituídas para participarem do que hoje é um direito seu: a esfera pública de decisão da política. Isso foi constatado a partir do convite que foi feito para a candidatura pelos partidos que a partir das cotas partidárias procuraram mais significativamente por mulheres para concorrer. Também se observou neste estudo o capital político de ingresso das mulheres nessa esfera: o capital familiar, capital dos movimentos sociais e capital de ocupação em cargos públicos. Quanto a participação das mulheres no cotidiano de seus mandatos identificamos a dificuldade de ser mulher e política na atualidade. As negociações com os partidos e os colegas, a conciliação entre a família e a vida pública; os focos de atuação dedicados as áreas sociais e nesse destacamos mais significativamente a educação. Por fim, o que pretendemos foi desconfiar da máxima “lugar de mulher não é na política” e conhecer as trajetórias e histórias de mulheres que cotidianamente entre conflitos e disputas lutam pelo seu lugar na esfera pública, pelo exercício de sua cidadania.

Roda dos sentidos: a formação continuada de professores em espaços de coletividade

A dissertação de mestrado aqui apresentada está vinculada ao Programa de Pós Graduação em Educação – PPGEdu, da Universidade Federal do Rio Grande – FURG, situada na linha de pesquisa Culturas, Linguagens e Utopias. O objetivo do estudo é contribuir para que os professores possam pensar em outras práticas de formação docente dentro dos espaços educativos nos quais atuam, desenvolvendo suas ações pedagógicas, a partir da reflexão sobre cotidiano docente no coletivo. A pesquisa envolve um grupo de professores que se propôs a estudar a categoria trabalho e seus entrelaçamentos com o trabalho docente a partir da perspectiva marxista. Tal grupo organizou-se tendo em vista a metodologia das Rodas de Formação, conforme a perspectiva de Warschauer, intitulando-se Roda dos Sentidos. Como corpus de análise foram utilizados os registros escritos em um portfólio coletivo, realizado a cada semana por um dos professores da Roda. Tal escrita era alternada entre os sujeitos para que, assim, todos contribuíssem, ao seu modo, na composição dos registros da Roda dos Sentidos. Foram analisadas as escritas dos anos de 2011 e 2012, buscando-se responder ao questionamento: ―que significados de formação docente são vivenciados em espaços coletivos como os da Roda dos Sentidos?‖ A análise dos dados foi inspirada na Análise Textual Discursiva – ATD, de Moraes e Galiazzi, inicialmente realizou-se a impregnação do material produzido pelos sujeitos da pesquisa, para então proceder com a unitarização, a construção de categorias analíticas e a escrita de metatextos. As problematizações realizadas no decorrer da dissertação foram apontando compreensões sobre a importância da formação docente no coletivo, constituída pelos estudos e diálogos vivenciados pelos sujeitos envolvidos; a compreensão das amarras do sistema societário que interferem no trabalho docente, salientando a necessidade dos professores resgatarem, enquanto categoria, sua capacidade de luta, seu sentido de união e coletividade no trabalho, fortalecendo suas representatividades através dos sindicatos; a compreensão da profissão docente como interpelada pelas relações humanas, ao entrelaçar a construção do conhecimento aos sentimentos como afetividade, respeito, alegria e esperança, envolvidos nesse processo, estão, nesse sentido, os professores constituindo sua humana docência. A partir das análises realizadas, compreender-se que as vivências de estudo e formação na Roda dos Sentidos, proporcionaram momentos de avanços teóricos, realizados a partir de diálogos sobre o trabalho e o trabalho docente, potencializados pelos registros escritos e compartilhados nos encontros da Roda, possíveis a partir da construção do sentido de coletividade, compreendendo-se, assim, a importância dos elos afetivos na constituição docente.

Modelagem eletroquímica e do distúrbio ácido-básico em atletas de karatê participantes do campeonato mundial WKO 2014

The objective of this study was to analyze the electrochemical and acid-base disorders in high performance athletes during the World Karate Championship hosted by the WKO (World Karate Organization) in 2014. In this study 19 male athletes were analyzed (age 34 ± 8), black belts and with over 5 years of experience in the sport. Capillary blood samples from the digital pulp of the finger were collected in three stages: rest, 5 minutes after and 10 minutes after fighting (kumite). The sample was analyzed using blood gas analyzer GEM Premier 3000, using the parameters pH, Na+, K+, Ca2+, lactate e HCO3−. The values related to acid-base disturbance presented statistical differences (p <0.05) in most of the collected moments. The lactate levels found were 2.77 ± 0.97mmol / L in rest, 6.57 ± 2.1 for 5 minutes after and 4.06 ± 1.55 for 10 minutes after combat. The samples collected for the electrolytic markers showed no statistical differences in their values (p <0.05). Through the data collected, we conjecture that the sport can be characterized as a high-intensity exercise and with a predominance of the glycolytic system. The analysis of acid-base disturbance is an efficient method to assist in the control of training loads.

Managing university records and documents in the world of governance, audit and risk: Case studies from South Africa and Malawi

There are enormous benefits for any organisation from practising sound records management. In the context of a public university, the importance of good records management includes: facilitating the achievement the university’s mandate; enhancing efficiency of the university; maintaining a reliable institutional memory; promoting trust; responding to an audit culture; enhancing university competitiveness; supporting the university’s fiduciary duty; demonstrating transparency and accountability; and fighting corruption. Records scholars and commentators posit that effective recordkeeping is an essential underpinning of good governance. Although there is a portrayal of positive correlation, recordkeeping struggles to get the same attention as that given to the governance. Evidence abounds of cases of neglect of recordkeeping in universities and other institutions in Sub-Saharan Africa. The apparent absence of sound recordkeeping provided a rationale for revisiting some universities in South Africa and Malawi in order to critically explore the place of recordkeeping in an organisation’s strategy in order to develop an alternative framework for managing records and documents in an era where good governance is a global agenda. The research is a collective case study in which multiple cases are used to critically explore the relationship between recordkeeping and governance. As qualitative research that belongs in the interpretive tradition of enquiry, it is not meant to suggest prescriptive solutions to general recordkeeping problems but rather to provide an understanding of the challenges and opportunities that arise in managing records and documents in the world of governance, audit and risk. That is: what goes on in the workplace; what are the problems; and what alternative approaches might address any existing problem situations. Research findings show that some institutions are making good use of their governance structures and other drivers for recordkeeping to put in place sound recordkeeping systems. Key governance structures and other drivers for recordkeeping identified include: laws and regulations; governing bodies; audit; risk; technology; reforms; and workplace culture. Other institutions are not managing their records and documents well despite efforts to improve their governance systems. They lack recordkeeping capacity. Areas that determine recordkeeping capacity include: availability of records management policy; capacity for digital records; availability of a records management unit; senior management support; level of education and training of records management staff; and systems and procedures for storage, retrieval and dispositions of records. Although this research reveals that the overall recordkeeping in the selected countries has slightly improved compared with the situation other researchers found a decade ago, it remains unsatisfactory and disjointed from governance. The study therefore proposes governance recordkeeping as an approach to managing records and documents in the world of governance, audit and risk. The governance recordkeeping viewpoint considers recordkeeping as a governance function that should be treated in the same manner as other governance functions such as audit and risk management. Additionally, recordkeeping and governance should be considered as symbiotic elements of a strategy. A strategy that neglects recordkeeping may not fulfil the organisation’s objectives effectively.

How effective are acoustic signals in territorial defence in the Lusitanian toadfish?

The function of fish sounds in territorial defence, in particular its influence on the intruder's behaviour during territorial invasions, is poorly known. Breeding Lusitanian toadfish males (Halobatrachus didactylus) use sounds (boatwhistles) to defend nests from intruders. Results from a previous study suggest that boatwhistles function as a 'keep-out signal' during territorial defence. To test this hypothesis we performed territorial intrusion experiments with muted Lusitanian toadfish. Males were muted by making a cut and deflating the swimbladder (the sound-producing apparatus) under anaesthesia. Toadfish nest-holder males reacted to intruders mainly by emitting sounds (sham-operated and control groups) and less frequently with escalated bouts of fighting. When the nest-holder produced a boatwhistle, the intruder fled more frequently than expected by chance alone. Muted males experienced a higher number of intrusions than the other groups, probably because of their inability to vocalise. Together, our results show that fish acoustic signals are effective deterrents in nest/territorial intrusions, similar to bird song.

Estudo das preferências do consumo de pão na região de Viseu

O pão, um dos alimentos mais consumidos a nível mundial, tem como principal função o fornecimento de energia ao organismo. Considerado como um alimento funcional é igualmente dotado de benefícios nutricionais que podem ajudar no combate do excesso de peso e obesidade, sendo indispensável para uma dieta saudável. Deste modo, o objetivo deste trabalho consiste em dar a conhecer os hábitos de consumo de pão e as preferências dos consumidores da região de Viseu, pretendendo-se aferir em que medida os hábitos de consumo, compras e entendimento relativo ao consumo do pão, diferem com base nas variáveis individuais. O estudo foi realizado através de um inquérito por questionário, por entrevista direta. Os dados demográficos, hábitos de consumo, compras e o entendimento relativo ao consumo de pão, foram os parâmetros selecionados para a estruturação do inquérito. A amostra era composta por 500 inquiridos, onde 35,40% pertenciam ao género masculino e 64,06% ao género feminino. A maioria da população em estudo gosta de pão e inclui pão na sua dieta. Observou-se que o pão de mistura era o pão mais consumido e a refeição onde se ingeria mais pão seria ao pequeno-almoço. Os filhos dos inquiridos ao pequeno-almoço consumiam mais leite e o pão era o terceiro alimento mais consumido. De um modo geral, os inquiridos valorizavam mais as características sensoriais no ato de compra do pão. O local mais requisitado para comprar de pão era a pastelaria. No que diz respeito ao nível de conhecimentos, a grande maioria dos inquiridos respondeu corretamente a pelo menos metade das questões. Pode-se concluir que o pão faz, em geral, parte da dieta alimentar da população da amostra em estudo. Comparativamente com um estudo nacional efetuado em 2011 pela Federação Portuguesa de Cardiologia e o Museu do Pão, existem semelhanças nos resultados, no que diz respeito às refeições onde se consome mais pão e ao tipo de pão consumido. Existe uma falha de informação a nível nacional, sobre o tema pão, havendo a necessidade de este tema ser mais estudado/explorado.

Content analysis model to analyze facets of social mission of public library on the Facebook and in the websites

In this paper we present the development and the implementation of a content analysis model for observing aspects relating to the social mission of the public library on Facebook pages and websites. The model is unique and it was developed from the literature. There were designed the four categories for analysis Generate social capital and social cohesion, Consolidate democracy and citizenship, Social and digital inclusion and Fighting illiteracies. The model enabled the collection and the analysis of data applied to a case study consisting of 99 Portuguese public libraries with Facebook page. With this model of content analysis we observed the facets of social mission and we read the actions with social facets on the Facebook page and in the websites of public libraries. At the end we discuss in parallel the results of observation of the Facebook of libraries and the websites. By reading the description of the actions of the social mission, the general conclusion and the most immediate is that 99 public libraries on Facebook and websites rarely publish social character actions, and the results are little satisfying. The Portuguese public libraries highlight substantially the actions in the category Generate social capital and social cohesion.

Um enfermeiro presidente da República. Você sabia?

Descreve a vida de Samora Machel, um enfermeiro moçambicano, que liderou guerrilhas até obter a independência e criar a República de Moçambique. Narrar sua história de vida e seu papel na saúde de seu país, tem por objetivo mostrar que a política pode ser um meio para que outros enfermeiros, em outros países, possam também seguir por esse caminho para o beneficio de toda uma população e através do exercício da liderança, também contribuir para melhorar a saúde e as condições de vida das comunidades. Além de lutar contra o racismo, a discriminação, o analfabetismo, a pobreza e a seca durante mais de dez anos em seu governo, Samora Machel teve que lutar internamente contra forças políticas oponentes. De qualquer modo, ele se tornou um exemplo em seu país onde é reverenciado e venerado como herói nacional.

Avaliação das atividades anti-inflamatória, anticoagulante e antiproliferativa do inibidor de quimotripsina das sementes de erythrina velutina (EvCI)

Studies indicate that several components were isolated from medicinal plants, which have antibacterial, antifungal, antitumor and anti-inflammatory properties. Sepsis is characterized by a systemic inflammation which leads to the production of inflammatory mediators exacerbated by excessive activation of inflammatory cells and disseminated intravascular coagulation (DIC), in which the human neutrophil elastase plays an important role in its pathogenesis. Several epidemiological studies suggest that components of plants, especially legumes, can play a beneficial role in reducing the incidence of different cancers. A chymotrypsin inhibitor of Kunitz (Varela, 2010) was purified from seeds of Erythrina velutina (Mulungu) by fractionation with ammonium sulfate, affinity chromatography on Trypsin-Sepharose, Chymotrypsin-Sepharose and ion exchange chromatography on Resource Q 1 ml (GE Healthcare) in system FPLC / AKTA. The inhibitor, called EvCI, had a molecular mass of 17 kDa determined by SDS-PAGE. The purified protein was able to inhibit human neutrophil elastase (HNE), with an IC50 of 3.12 nM. The EvCI was able to inhibit both pathways of HNE release stimulated by PAF and fMLP (75.6% and 65% respectively). The inhibitor also inhibited leukocyte migration in septic mice about 87% and prolonged the time of coagulation and inhibition factor Xa. EvCI showed neither hemolytic activity nor cytotoxicity. EvCI showed a selective antiproliferative effect to HepG2 cell lines with IC50 of 0.5 micrograms per milliliter. These results suggest EvCI as a molecule antagonist of PAF / fMLP and a potential use in fighting inflammation related disorders, disseminated intravascular coagulation (DIC) and cancer

O fenômeno da corrupção na esfera pública brasileira

This work aims to understand the phenomenon of corruption in the Brazilian public sphere and its implications for society. It has brought concepts of corruption, and has referred to its highest incidence in the public sphere in the three levels of government (despite its infiltration also in the privative sector) and has called attention to two subjects which intertwine public administration (as a means of ordering social life) and corruption (as a form of denial to the collective welfare). Through literature search whose analysis shows that the phenomenon contains the entire country history, from discovery to present day it was found to be common several dictatorial and democratic political regimes. Finally, it has emphasized the importance and necessity of citizen participation in process, as well as the organization of civil society and media, in addition to highlighting the relevance of autonomy and independence of Powers set for its effective confrontation and fighting

More Than A Movement: Unpacking Contemporary Anti-Human Trafficking Efforts in Washington, D.C.

Trafficking in persons has attracted seemingly boundless attention over the last two decades and the work aimed at fighting it is best understood when this cause is contextualized against the backdrop of other social forces—economic, social, and cultural—shaping contemporary nonprofit activities. This project argues that the paid and volunteer labor that takes place in metro Washington, D.C., to combat trafficking in persons can be understood as both a movement and an industry. In addition to arguing that anti-trafficking work is part of a nonprofit industrial complex that situates activist and advocacy work firmly inside state and economic institutions, this project is concerned with the ways in which trafficking work and workers conduct their business collectively. As an organizational study, it identifies the key players in the D.C. region focused on this issue and traces their interactions, collaborations, and cooperation. Significantly, this project suggests that despite variations in objectives, methods, priorities, and characterizations of trafficking, thirty organizations in metro D.C. working on this issue “get along” because they are bound by the benign common goal of raising awareness. Awareness, in this context, is best understood as both a cultural anchor facilitating cohesion and as a social currency allowing groups to opt into joint efforts. The dissertation concludes that organizations centralize awareness in their collective activities over more drastic priorities around which consensus would need to be gained. This is a lost opportunity for making sense of the ways that individual bodies—men, women, and children—experience not just trafficking, but the world around them.

Espionage against Poland in the Documents and Analyses of the Polish Special Services (1944 - 1989) - as Illustrated by the Intelligence Activities of the USA

The text analyses the intelligence activity against Poland in the period 1944-1989. The paper also contains a case study, i.e. an analysis of the American intelligence service activity held against Poland. While examining the research thesis, the author used the documents and analyses prepared by the Ministry of Internal Affairs. In order to best illustrate the point, the author presented a number of cases of persons who spied for the USA, which was possible thanks to the analysis of the training materials of the Ministry of Internal Affairs directed to the officers of the Security Service and the Citizens’ Militia. The text tackles the following issues: (1) to what extent did the character of the socio-political system influence the number of persons convicted for espionage against Poland in the period under examination?, (2) what was the level of interest of the foreign intelligence services in Poland before the year 1990?, (3) is it possible to indicate the specificity of the U.S. intelligence activity against Poland? 1) The analysis of data indicates that the period 1946-1956 witnessed a great number of convictions for espionage, which is often associated with the peculiar political situation in Poland of that time. Up to 1953, the countries of the Eastern bloc had reproduced the Stalin’s system, which only ceased due to the death of Stalin himself. Since then, the communist systems gradually transformed into the system of nomenklatura. Irrespective of these changes, Poland still witnessed a wave of repressions, which resulted from the threats continuously looming over the communist authorities – combating the anti-communist underground movement, fighting with the Ukrainian Insurgent Army, the Polish government-in-exile, possible revisionism of borders, social discontent related to the socio-political reforms. Hence, a great number of convictions for espionage at that time could be ascribed to purely political sentences. Moreover, equally significant was the fact that the then judicial practice was preoccupied assessing negatively any contacts and relations with foreigners. This excessive number of convictions could ensue from other criminal-law provisions, which applied with respect to the crimes against the State, including espionage. What is also important is the fact that in the Stalin’s period the judiciary personnel acquired their skills and qualifications through intensive courses in law with the predominant spirit of the theory of evidence and law by Andrey Vyshinsky. Additionally, by the decree of 1944 the Penal Code of the Polish Armed Forces was introduced; the code envisaged the increase in the number of offences classified as penalised with death penalty, whereas the high treason was subject to the military jurisdiction (the civilians were prosecuted in military courts till 1955; the espionage, however, still stood under the military jurisdiction). In 1946, there was introduced the Decree on particularly dangerous crimes in the period of the State’s recovery, which was later called a Small Penal Code. 2) The interest that foreign intelligence services expressed in relation to Poland was similar to the one they had in all countries of Eastern and Central Europe. In the case of Poland, it should be noted that foreign intelligence services recruited Polish citizens who had previously stayed abroad and after WWII returned to their home country. The services also gathered information from Poles staying in immigrant camps (e.g. in FRG). The activity of the American intelligence service on the territory of FRG and West Berlin played a key role. The documents of the Ministry of Internal Affairs pointed to the global range of this activity, e.g. through the recruitment of Polish sailors in the ports of the Netherlands, Japan, etc. In line with the development in the 1970s, espionage, which had so far concentrated on the defence and strategic sectors, became focused on science and technology of the People’s Republic of Poland. The acquisition of collaborators in academic circles was much easier, as PRL opened to academic exchange. Due to the system of visas, the process of candidate selection for intelligence services (e.g. the American) began in embassies. In the 1980s, the activity of the foreign intelligence services concentrated on the specific political situation in Poland, i.e. the growing significance of the “Solidarity” social movement. 3) The specificity of the American intelligence activity against Poland was related to the composition of the residency staff, which was the largest in comparison to other Western countries. The wide range of these activities can be proved by the quantitative data of convictions for espionage in the years 1944-1984 (however, one has to bear in mind the factors mentioned earlier in the text, which led to the misinterpretation of these data). Analysing the data and the documents prepared by the Ministry of Internal Affairs, one should treat them with caution, as, frequently, the Polish counter-intelligence service used to classify the ordinary diplomatic practice and any contacts with foreigners as espionage threats. It is clearly visible in the language of the training materials concerned with “secret service methods of the intelligence activity” as well as in the documents on operational activities of the Security Service in relation to foreigners. The level of interest the USA had in Poland was mirrored in the classification of diplomatic posts, according to which Warsaw occupied the second place (the so-called Group “B”) on the three-point scale. The CIA experienced spectacular defeats during their activity in Poland: supporting the Polish underground anti-communist organisation Freedom and Independence and the so-called Munich-Berg episode (both cases took place in the 1950s). The text focuses only on selected issues related to the espionage activities against Poland. Similarly, the analysis of the problem has been based on selected sources, which has limited the research scope - however, it was not the aim of the author to present the espionage activity against Poland in a comprehensive way. In order to assess the real threat posed by the espionage activity, one should analyse the case of persons convicted for espionage in the period 1944-1989, as the available quantitative data, mentioned in the text, cannot constitute an explicit benchmark for the scale of espionage activity. The inaccuracies in the interpretation of data and variables, which can affect the evaluation of this phenomenon, have been pointed out in the text.
