Design and development of a one-degree-of-freedom force-reflecting manual controller prototype for teleoperation

The present research is carried out from the viewpoint of primarily space applications where human lives may be in danger if they are to work under these conditions. This work proposes to develop a one-degree-of-freedom (1-DOF) force-reflecting manual controller (FRMC) prototype for teleoperation, and address the effects of time delays commonly found in space applications where the control is accomplished via the earth-based control stations. To test the FRMC, a mobile robot (PPRK) and a slider-bar were developed and integrated to the 1-DOF FRMC. The software developed in Visual Basic is able to telecontrol any platform that uses an SV203 controller through the internet and it allows the remote system to send feedback information which may be in the form of visual or force signals. Time delay experiments were conducted on the platform and the effects of time delay on the FRMC system operation have been studied and delineated.

Landscape of fear : a social history of the missile during the early years of the cold war, 1950-1965

The missile's significance has been central to national security since the Soviet launching of Sputnik, and became increasingly important throughout the years of the Cold War. Much has been written about missile technology, but little has been written about how the development and deployment of this weapon affected Americans. The missile was developed to both deter war but also to win war. Its presence, however, was not always reassuring. Three areas of the United States are studied to evaluate the social implications of the missile during these pivotal years: San Francisco, home of multiple Nike installations; of Cape Canaveral, Florida, the nation's primary missile test center; the Great Plains, the location of the largest ICBM concentration in the country. Interviews were conducted, tours of facilities were taken, and local newspapers were reviewed. In conjunction with national newspapers and magazines and public opinion polls, this information provided a local social context for missile history. Nationally and locally, Americans both feared and praised the new technology. They were anxious for government funding in their cities and often felt that the danger the missile brought to their communities by making it as a Soviet target was justified in the larger cause for national security.

Labor turnover : its causes, consequences, and control strategy in five selected restaurants in the Miami area

The purpose of this study is to identify and analyze the basic causes of food service employee turnover in five selected restaurants in the Miami area. The withdrawal behavior in this study is treated in terms of controllable turnover, for the purpose of management, learning more about what action to take to solve this problem which has eaten into the fabric of the hospitality industry. The aim is to find out from the food service employees and management view of work for the purpose of identifying the variables which cause an employee to voluntarily leave a job. The objective is therefore, to analyze and describe the problem of labor turnover in these selected restaurants. Such description must precede efforts to arrive at solutions to the problem if these efforts are ever to be more than haphazard and superficial. Sigmund Freud once stated: "The true beginning of scientific activity consists in describing phenomena and only then in proceeding to group, classify and correlate them."1 The nature of the study is basically descriptive survey. Data is collected by the use of management questionnaire, food service employee questionnaire and finally employees job description index. The survey consisted of a series of well defined questions with open and closed endings dealing with employee with employee turnover. As Robert Ferber and P. J. Verdoom state in their book titled Research Method in Economics of Business: "Structured questionnaires, by supplying question formulations in very specific terms as well as the different possible answers are easier for the sample members to answer and also serve to reduce the danger of interviewer bias."2 The answers to the prepared questionnaire by sample members were then recorded. The results of the questionnaire responses were then compiled for presentation and analysis. 1 Julian Simon, Basic Research Methods in Social Science. Random House, New York, 1969, p.53. 2 Robert J.

Reflexões fenomenológicas sobre o sofrimento em relação ao trabalho

The literature review reveals that the field of Work Organizational Psychology, as well as the Mental Health of Work has been developing relevant research about the suffering and the world of work. This research intended to approach the unique experience of suffering in relation of the work, from the clinical view, taking the Heidegger’s phenomenological hermeneutics perspective as a reference. Inspired by the thought of the philosopher, sought to understand the suffering in their ontic and existential dimensions, in its limiting aspects; as the one who restricts the possibilities of relationship that man with others, putting in danger significances networks woven for him to deal with things and to live with others. The world of work has been envisioned as a space of possibilities for realization of the existence. Thus, the objective of this study is to understand how the suffering is experienced in relation to work, from the experience of professionals inserted in a judicial organization. The research, with the qualitative approach, used semi-structured individual interviews, whose narratives were analyzed from the heideggerian hermeneutic perspective. Three employees collaborated into this research. The narratives showed that the suffering is related with excess and diversity of tasks carried out by the same employee, associated with lack of acknowledgment of the work executed, and also with working relationship. In general way, the suffering revealed itself as helplessness, loneliness and lack of sense to the existence. We hope that this study enables the opening towards new horizons of understanding about the meanings and sense of work and their relationship networks, as well as contributes to the field of psychology in general

O direito penal do inimigo na atualidade: Mutual Legal Assistance Treaty – MLAT, em matéria penal, celebrado entre a República Federativa do Brasil e os Estados Unidos da América bem como seus reflexos na jurisdição brasileira

In view of the climate of instability and deep social inequalities, it has been evident in the Brazilian reality, a new way to punish systematic already developed and consolidated in other countries, in which, among other things, the criminality is anticipated only by danger that the individual sports. It appears, therefore, that the theory developed by Günter Jakobs, nominated Criminal Law of the Enemy, became subtly inserted in the Brazilian reality as well as in international relations signed. In this sense, the Brazilian State, in order to carry out the international legal cooperation in the criminal field, signed a mutual assistance agreement with the government of the United States of America. Forward the conclusion of Mutual legal Assistance Treaty (MLAT), the signatory countries voiced a desire to cooperate in order to facilitate the implementation of tasks of the authorities responsible for law enforcement in both countries, comprising research, investigation, prosecution and prevention of crime, said internalized adjustment in the Brazilian legal system by means of Decree No. 3810 of 02 May 2001. Alongside these considerations, the present study aims to analyze the Criminal law of the Enemy today, seeking to find evidence of that theory in the MLAT, international legal cooperation instrument signed between the government of the Federative Republic of Brazil and the government of the United States of America. Moreover, it has the objective to describe its effects on the Brazilian jurisdiction, especially as concerns the relativity and the suppression of human rights. Once done the introit, analysis will be carried out in the first chapter, on the definition and main features of the theory of Criminal Enemy of the law, it is imperative to approach the humanistic aspect that preceded the theory as well as the dealings given to some controversial issues surrounding it, such as the anticipation of the enemy's punishment and the disproportionality of the penalties imposed. In the second chapter will present the conceptual assumptions, historical evolution and the positives aspects, as well as the barriers and the pursuit of effectiveness of international legal cooperation. In the chapter, bedroom effective analysis of specific modality of cooperation will be held, the Mutual legal Assistance Treaty - MLAT in criminal matters, signed between the Federative Republic of Brazil and the United States of America, in which the general aspects will be addressed and the MLAT reflections on the Brazilian jurisdiction, which includes analysis about the relativity or suppression of human rights, future trends and creating stricter laws, followed by the presentation of the seized conclusion on the subject, in which, among other approaches, will be voiced understanding about the unconstitutionality certain service requests that, from these, there is the bad use of the agreed instrument.

Seismic Retrofitting of a Historic Structure with Limited Construction Documentation

Many buildings constructed during the middle of the 20th century were constructed with criteria that fall short of current requirements. Although shortcomings are possible in all aspects of the design, the inadequacies in terms of seismic design present a more pressing issue to human life. This risk has been seen in various earthquakes that have struck Italy recently, and subsequently, the codes have been altered to account for this underestimated danger. Structures built after these changes remain at risk and must be retrofitted depending on their use. This report centers around the Giovanni Michelucci Institute of Mathematics at the University of Bologna and the work required to modify the building so that it can withstand 60% of the current design requirements. The goal of this particular report is to verify the previous reports written in Italian and present an accurate analysis along with intervention suggestions for this particular building. The work began with an investigation into the previous sources and work to find out how the structure had been interpreted. After understanding the building, corrections were made where required, and the failing elements were organized graphically to more easily show where the building needed the most work. Once the critical zones were mapped, remediation techniques were tested on the top floor, and the modeling techniques and effects of the interventions were presented to assist in further work on the structure.

A crença sobre a morte e o coping religioso-espiritual em pacientes internados com doenças crônicas

The human being is understood as an integral being, complex, which has multiple dimensions: social, biological, psychological, anthropological, spiritual and others. As its biological dimension, the man presents the possibility of physical illness, which means that the body requires care. The sick away from humans in health and safety conditions, approaching them directly from the finitude and vulnerability condition, leading us to contact the major uncertainties of life: suffering of disease and death. Religiosity and spirituality are important coping strategy for human when faced with borderline situations. When people turn to religion to cope with stress is the religious and spiritual coping. The objective of this research was to evaluate the relationship between the views on death and the religious-spiritual coping in patients with chronic diseases hospitalized. The study included ten patients hospitalized for chronic disease complications Medical Clinic Unit of a public hospital in the city of Uberlândia/MG. two psychological scales were used: Scale Religious-Spiritual Coping Brief (CRE-Brief Scale) and Scale Brief Diverse Perspectives of Death and a structured interview (audiogravada) on the subject of death and religious and spiritual coping. The results indicated that 80% of the sample (N = 8) consisted of patients hospitalized due to chronic diseases, while 20% accounted for patients with AIDS complications. Analyzing the results of scale CRE-Brief, it emphasizes the use of strategies of religious and spiritual coping by participants as compared to CRE Total, all study participants had average or high scores for this index, with a low utilization CRE negative and average utilization CRE Positive. Regarding views on death, the results obtained by the Different Perspectives Quick Scale on Death suggest that this sample agrees with the view death as something that is part of the natural cycle of life (M8 - Death as a natural end) and features the prospect of death as uncertainty, mystery and ignorance (M4 - death as Unknown). The correlations between the measures the factors and items of CRE-Bref and dimensions of Short scales on different perspectives of Death notes the prevalence of correlations of M4 dimensions - Death as unknown and M8 - Death as a natural order to the creditor scale soon. In the interview analysis revealed a positive influence of religion/ spirituality on health, from the perspective of the respondent, highlighting the protection promoted by religion. It also noticed the use of prayer as a coping strategy of hospitalization and illness. Regarding the interview about the topic of death, there was a predominance of issues related to "afterlife", "unknown" and "abandonment", which are associated with the visions of death and mystery and death as a natural end. In the interviews there belief clues about death as a terrifying mystery connected, so the unknown and the feeling of fear on the same. The experience of illness can therefore be considered as a source of vulnerability, since it is present personal perception of danger (external) - own illness and possible death, especially in those patients undergoing ICU - and where control is insufficient for the sense of security, since the hospital providing care to the patient are delegated to third parties and patients assume a passive role. This fact is important and relevant to health professionals who deal daily with patients hospitalized for chronic diseases, since the recourse to religion and spirituality as a coping strategy that psychic movement was not constituted in a form of negative distance or even denial of health condition. On the contrary, it refers to a movement in search of comfort and security provided by the religion and spirituality.

The making and unmaking of heritage

Heritage is defined by history which is by nature multi layered. The passage of time and the perspectives it affords, enables and even necessitates constant reexamination and reinterpretation of history. What effect do changes in historical perspective then have upon the definition of heritage which relies on an understanding of its history? The present paper attempts to engage with the notion of heritage, criteria of its definition, and the mutable nature of such designations with specific reference to architectural constructions and historical cities that enjoy or have enjoyed in the past the status of a ‘World Heritage Site’. Examples such as the Louvre museum in Paris or the King’s Cross station in London make an interesting study as they not only allow insight into the past but reflect the changes and adaptation over a period of time. Multiple alterations, some very recently, have modified them extensively since the time they were accorded the ‘World Heritage Site’ status. The above examples are contrasted by sites ridden with conflict such as the Bamiyan Valley. This site has been placed under the ‘World Heritage In Danger’ list by UNESCO taking into account the destruction of the Buddha statues in the region. The act of vandalism itself has had dual implications. While causing an irreparable loss to mankind of its heritage, it also serves as an effective symbol of religious fanaticism that is a pressing concern of our times. The paper then moves on to explore the case of Dresden which lost its ‘World Heritage’ status with the construction of the Waldschlösschen Bridge. This is a particularly interesting case because with the absolute destruction of the city during the Second World War, it was necessary to reconstruct the historical city while simultaneously acknowledging and addressing the modern day requirements. During the reconstruction, with the readaptation of the spaces, it was almost impossible to replicate the original architectural program or to undertake such a large reconstruction project employing only the traditional techniques and materials. This essentially made it a new city constructed in the image of the old. The recent necessity of a growing city was met by the construction of a bridge that has caused it to lose its ‘World Heritage’ status. Finally, this paper endeavours to foster discussion of questions central to the definition of heritage such as what happens when we have to adapt a living space to avoid its deterioration and descent into dereliction by overuse. Does it necessarily lose its historical value? What exactly is Historical value?.

Information Interventions to Reduce Maternal Mortality in Indonesia

Indonesia consistently records higher levels of maternal mortality than other countries in Southeast Asia with its same level of socioeconomic development. I use a quasi-experimental, difference-in-differences approach to understand whether the role of information on the risk of death in childbirth can change women’s reproductive behaviors. In the first two chapters, I use the Maternal Mortality Module from the Demographic and Health Survey (DHS) in Indonesia to examine fertility and reproductive behavior responses to a sister’s death in childbirth. Fertility desires remain relatively unchanged but women take up behaviors in subsequent births that avert the risk of maternal death. In the last chapter, I combine population-representative data from the DHS with a village-level census (PODES) on service availability to understand how a village-level intervention to improve obstetric service use using a birth preparedness and complications readiness (BPCR) approach may improve obstetric service use. In this study, I find that the Desa Siaga intervention in Indonesia improved knowledge of the danger signs of complications among women but not among men relative to villages that did not get the program while controlling for endogenous program placement. More women got antenatal care due to the program but use of a skilled birth attendant and postpartum care did not change as a result of the intervention. Both genders report discussing a blood donor in preparation for delivery.

Wounds that heal and wounds that don't - The role of the IL-33/ST2 pathway in tissue repair and tumorigenesis

IL-33 is a member of the IL-1 family of cytokines. IL-33 is predominantly located within the nucleus of cells where it plays a role in gene regulation. Given the right combination of signals and cellular damage, stored IL-33 is released from the cell where it can interact with its receptor ST2, triggering danger-associated responses and act as a cellular "alarmin". Whilst IL-33/ST2 signalling has been shown to induce potent pro-inflammatory responses that can be detrimental in certain disease states, a dichotomous, protective role of IL-33 in promoting wound healing has also emerged in multiple tissues types. This review will explore the current literature concerning this homeostatic role of IL-33/ST2 in tissue repair and also review its role in uncontrolled wound responses as seen in both fibrosis and tumorigenesis.
