This paper introduced the system of real-time pulse signal acquisition based on CC2430.the original pulse signal was collected by projected pulse sensor, and then after shaping, filtering and amplification, we can get the pulse wave signal, which was stable and synchronized with the heart. After that this signal was input to the CC2430 chip, and reached the PC by ZigBee wireless communication, therefore the real-time monitoring from doctor to patient could be achieved. There were many advantages, such as simple, low power consumption, real-time coercion, etc. We can also expand the functional modules interfaces ,such as body temperature, ECG, blood pressure, to achieve the real-time monitoring more physiological parameters.

Over the past several years, transplantology has become one of the fastest developing areas of medicine. The reason is, first and foremost, a significant improvement of the results of successful transplants. However, much controversy arouse among the public, on both medical and ethical grounds. The article presents the most important concepts and regulations relating to the collection and transplantation of organs and tissues in the context of the European Convention on Bioethics. It analyses the convention and its additional protocol. The article provides the definition of transplantation and distinguishes its types, taking into account the medical criteria for organ transplants. Moreover, authors explained the issue of organ donation ex vivo and ex mortuo. The European Convention on Human Rights and Biomedicine clearly regulates the legal aspects concerning the transplantation and related basic concepts, and therefore provides a reliable source of information about organ transplantation and tissue. This act is a part of the international legal order, which includes the established codification of bioethical standards.

This chapter addresses the question of which syntactic environment constitutes the most reliable source of information on variable object placement in Latin. The relevance of this question is illustrated by showing that very different results are obtained when one compares the rate of VO in two different syntactic contexts, namely clauses with a single synthetic verb and clauses with a modal verb and a dependent infinitive. It is argued that the OV/VO alternation is best studied to clauses with more than one verb, as in such clauses, more object positions can be unambiguously identified. The final part of the chapter is devoted to the phrase structure analysis of clauses with the modals possum ‘be able’ and debeo ‘have to’. These structures are argued to constitute monoclausal domains, in which the modals are raising predicates that originate in functional heads in the extended projection of lexical verbs.

AbstractMedieval Romance texts in the Greek alphabet are generally considered a very reliable source of information about spoken vernacular varieties, mainly due to the intrinsic independence of their writers from the Latin graphic tradition. Nevertheless, as first observed by Alberto Varvaro and Anna Maria Compagna in 1983, these valuable documents, like any other kind of written evidence, are not immune from some degree of conventionality. This paper will focus on the problems raised by the codification of Romance languages in the Greek alphabet, which requires the study of multilingualism, language contact and coexistence of different (written and oral) cultural traditions. Exemplification will come from Italo-Romance texts produced in Sicily and Southern Italy before 1500, but also from texts of other Romance areas like the Gallo-Romance 13th Century

Regular monitoring of common physiological signs, including heart rate, blood pressure, and oxygen saturation, can be an effective way to either prevent or detect many kinds of chronic conditions. In particular, cardiovascular diseases (CVDs) are a worldwide concern. According to the World Health Organization, 32% of all deaths worldwide are from CVDs. In addition, stress-related issues cost $190 billion in healthcare costs per year. Currently, contact devices are required to extract most of an individuals physiological information, which can be uncomfortable for users and can cause discomfort. However, in recent years, remote photoplethysmography (rPPG) technology is gaining growing interest, which enables contactless monitoring of the blood volume pulse signal using a regular camera, and ultimately can provide the same physiological information as a contact device. In this paper, we propose a benchmark comparison using a new multimodal database consisting of 56 subjects where each subject was submitted to three different tasks. Each subject wore a wearable device capable of extracting photoplethysmography signals and was filmed to allow simultaneous rPPG signal extraction. Several experiments were conducted, including a comparison between information from contact and remote signals and stress state recognition. Results have shown that in this dataset, rPPG signals were capable of dealing with motion artifacts better than contact PPG sensors and overall had better quality if compared to the signals from the contact sensor. Moreover, the statistical analysis of the variance method had shown that at least two HRV features, NNi 20 and SAMPEN were capable of differentiating between Stress and Non-Stress states. In addition, three features, IBI, NNi 20, and SAMPEN were capable of differentiating between tasks relating to different levels of difficulty. Furthermore, using machine learning to classify a stressed or unstressed state, the models were able to achieve an accuracy score of 83.11%.

The ambiguity regarding the mechanism and limits of the authority of the arresting operations carried out by the corruption eradication commission raises public assumption that the authority exercised by the corruption eradication commission has violated the law and even violated human rights, namely taking arbitrary actions (unprocedure).The problem in writing this study is How can the legal force of the operation of the corruption eradication commission arrest if viewed from the aspect of the Criminal Procedure Code and Law Number 30 of 2002 Concerning the Corruption Eradication Commission? What are the criteria for an alleged crime using a arrest operation? What is the ideal way for the Corruption Eradication Commission to carry out arrest operations? This study uses a Normative and Empirical Juridical approach. Normative research is carried out on matters that are theoretical principles of law, whereas an empirical approach is carried out to study law in reality. The results of the study found that legal force of the act of arrest operations of the corruption eradication commission if viewed from the aspect of the Criminal Procedure Code and Law Number 30 of 2002 Concerning the Corruption Eradication Commission actually the act of arrest operations of the corruption eradication commission does not have a strong legal basis from the juridical aspects of criminal law. problem of violating the principle of due processof law Criteria for Alleged Crime Using a hand arrest operation due to the type or quality of the target of corruption is not a simple crime and therefore the need for a hand arrest operation, and ideally the commission of asan corruption In carrying out arrest operations, it is necessary to have a good case administration system starting from the stage of collecting data and information that is based on an accurate and reliable source of information, after that conducting an investigation in accordance with the standard operating procedures that have been determined then at the execution stage such as conduct monitoring, undercover, tapping and then the operation of arresting the authority must be in accordance with the legislation. The suggestion that can be done is that the legal basis for Operation of Catching Hands must be immediately included in the article instrument in the corruption eradication commission law so that its authority is not at issue

Abstract With the goal of achieving consistence in interpretation of an arterial pulse signal between its vibration model and its hemodynamic relations and improving its physiological implications in our previous study, this paper presents an improved vibration-model-based analysis for estimation of arterial parameters: elasticity (E), viscosity (η), and radius (r0) at diastolic blood pressure (DBP) of the arterial wall, from a noninvasively measured arterial pulse signal. The arterial wall is modeled as a unit-mass vibration model, and its spring stiffness (K) and damping coefficient (D) are related to arterial parameters. Key features of a measured pulse signal and its first-order and second-order derivatives are utilized to estimate the values of K and D. These key features are then utilized in hemodynamic relations, where their interpretation is consistent with the vibration model, to estimate the value of r0 from K and D. Consequently, E, η, and pulse wave velocity (PWV) are also estimated from K and D. The improved vibration-model-based analysis was conducted on pulse signals of a few healthy subjects measured under two conditions: at-rest and immediately post-exercise. With E, r0, and PWV at-rest as baseline, their changes immediately post-exercise were found to be consistent with the related findings in the literature. Thus, this improved vibration-model-based analysis is validated and contributes to estimation of arterial parameters with better physiological implications, as compared with its previous counterpart.

On their own, photos and videos are not a reliable source of information about what is taking place in a school. It’s easy to react emotionally or with outrage to a video of a fight, a child being picked on, or some other display of abuse or wrongdoing. But everyone knows from highly publicized incidents posted on YouTube, Twitter, or other social media sites that photos and videos can be taken out of context. They tell a story, but they don’t tell the whole story. Even so, they can be used by administrators to discern whether the action shown in the photo or video is an isolated incident or could be a symptom of a larger problem. If an alarming photo or video taken at a school is receiving attention from the media, it’s better to talk about it with the school community as soon as possible than to pretend it didn’t happen. Situations like these create an opportunity to examine and share other sources of data about school safety, violence, and victimization. Too often, one incident can cause the public to draw conclusions about a school that are not accurate. That’s why a monitoring system is necessary— to put such an incident in context. Administrators who can refer to other sources of data regarding violence, drug use, or weapons can respond with more confidence when faced with criticism over one incident. As part of a monitoring system, photos, videos and other technology can be used for positive purposes. They allow students who might skip questions on a survey or don’t want to speak up during a focus group to express themselves in a different way. There are many examples of projects in which students are given cameras and microphones and encouraged to express themselves and present their experiences in school through this media. In addition to the individual students benefitting from such experiences, school leaders, staff members, and parents get the opportunity to see the school from the students’ perspectives.
