Aims: Feasibility study of accurate three lead ECG recording (Einthoven I, II and III) using an Apple Watch Series 4. Methods: In 50 healthy subjects (18 male; age: 40 ± 12 years) without known cardiac disorders, a 12-lead ECG and three bipolar ECGs, corresponding to Einthoven leads I, II and III were recorded using an Apple Watch Series 4. Einthoven I was recorded with the watch on the left wrist and the right index finger on the crown, Einthoven II with the watch on the left lower abdomen and the right index finger on the crown, Eindhoven III with the watch on the left lower abdomen and the left index finger on the crown. Four experienced cardiologists were independently asked to assign the watch ECGs to Einthoven leads from 12-lead ECG for each subject. Results: All watch ECGs showed an adequate signal quality with 134 ECGs of good (89%) and 16 of moderate signal quality (11%). Ninety-one percent of all watch ECGs were assigned correctly to corresponding leads from 12-lead ECG. Thirty-nine subjects (78%) were assigned correctly by all cardiologists. All assignment errors occurred in patients with similar morphologies and amplitudes in at least two of the three recorded leads. Erroneous assignment of all watch ECGs to leads from standard ECG occurred in no patient. Conclusion: Recording of Einthoven leads I-III by a smartwatch is accurate and highly comparable to standard ECG. This might contribute to an earlier detection of cardiac disorders, which are associated with repolarization abnormalities or arrhythmias.

Every year cardiovascular diseases kill the highest number of people worldwide. Among these, pathologies characterized by sporadic symptoms, such as atrial fibrillation, are difficult to be detected as state-of-the-art solutions, e.g., 12-leads electrocardiogram (ECG) or Holter devices, often fail to tackle these kinds of pathologies. Many portable devices have already been proposed, both in literature and in the market. Unfortunately, they all miss relevant features: they are either not wearable or wireless and their usage over a long-term period is often unsuitable. In addition, the quality of recordings is another key factor to perform reliable diagnosis. The ECG WATCH is a device designed for targeting all these issues. It is inexpensive, wearable (size of a watch), and can be used without the need for any medical expertise about positioning or usage. It is non-invasive, it records single-lead ECG in just 10 s, anytime, anywhere, without the need to physically travel to hospitals or cardiologists. It can acquire any of the three peripheral leads; results can be shared with physicians by simply tapping a smartphone app. The ECG WATCH quality has been tested on 30 people and has successfully compared with an electrocardiograph and an ECG simulator, both certified. The app embeds an algorithm for automatically detecting atrial fibrillation, which has been successfully tested with an official ECG simulator on different severity of atrial fibrillation. In this sense, the ECG WATCH is a promising device for anytime cardiac health monitoring.

Consumer rhythm-monitoring devices, such as the Apple Watch, are becoming more readily available. Irregular pulses can be detected using an optical sensor that is built into the wearable device. The Apple Watch (Apple Inc., Cupertino, CA, USA) is a class II medical device with pulse rate and electrocardiography (ECG) monitoring capabilities. Here, we report a case in which an arrhythmia that was conventionally perceived but undiagnosed was identified as an atrial fibrillation by the self-acquisition of the ECG data using an Apple Watch.

Some of the recently released smartwatch products feature a single-lead electrocardiogram (ECG) recording capability. The reliability of obtaining 3-lead ECG with smartwatches is yet to be confirmed in a large study. This study aimed to assess the feasibility and reliability of smartwatch to obtain 3-lead ECG recordings, the classical Einthoven ECG leads I-III compared to standard ECG. To record lead I, the watch was worn on the left wrist and the right index finger was placed on the digital crown for 30 s. For lead II, the watch was placed on the lower abdomen and the right index finger was placed on the digital crown for 30 s. For lead III, the same process was repeated with the left index finger. Spearman correlation and Bland-Altman tests were used for data analysis. A total of 300 smartwatch ECG tracings were successfully obtained. ECG waves’ characteristics of all three leads obtained from the smartwatch had a similar duration, amplitude, and polarity compared to standard ECG. The results of this study suggested that the examined smartwatch (Apple Watch Series 4) could obtain 3-lead ECG tracings, including Einthoven leads I, II, and III by placing the smartwatch on the described positions.

Background: Smartwatches that are able to record a bipolar ECG and Einthoven leads were recently described. Nevertheless, for detection of ischemia or other cardiac diseases more leads are required, especially Wilson’s chest leads. Objectives: Feasibility study of six single-lead smartwatch (Apple Watch Series 4) ECG recordings including Einthoven (I, II, III) and Wilson-like pseudo-unipolar chest leads (Wr, Wm, Wl). Methods: In 50 healthy subjects (16 males; age: 36 ± 11 years, mean ± SD) without known cardiac disorders, a standard 12-lead ECG and a six single-lead ECG using an Apple Watch Series 4 were performed under resting conditions. Recording of Einthoven I was performed with the watch on the left wrist and the right index finger on the crown, Einthoven II was recorded with the watch on the left lower abdomen and the right index finger on the crown, Einthoven III was recorded with the watch on the left lower abdomen and the left index finger on the crown. Wilson-like chest leads were recorded corresponding to the locations of V1 (Wr), V4 (Wm) and V6 (Wl) in the standard 12-lead ECG. Wr was recorded in the fourth intercostal space right parasternal, Wm was recorded in the fifth intercostal space on the midclavicular line, and Wl was recorded in the fifth intercostal space in left midaxillary line. For all Wilson-like chest lead recordings, the smartwatch was placed on the described three locations on the chest, the right index finger was placed on the crown and the left hand encompassed the right wrist. Both hands and forearms also had contact to the chest. Three experienced cardiologists were independently asked to allocate three bipolar limb smartwatch ECGs to Einthoven I–III leads, and three smartwatch Wilson-like chest ECGs (Wr, Wm, Wl) to V1, V4 and V6 in the standard 12-lead ECG for each subject. Results: All 300 smartwatch ECGs showed a signal quality useable for diagnostics with 281 ECGs of good signal quality (143 limb lead ECGs (95%), 138 chest lead ECGs (92%). Nineteen ECGs had a moderate signal quality (7 limb lead ECGs (5%), 12 chest lead ECGs (8%)). One-hundred percent of all Einthoven and 92% of all Wilson-like smartwatch ECGs were allocated correctly to corresponding leads from 12-lead ECG. Forty-six subjects (92%) were assigned correctly by all cardiologists. Allocation errors were due to similar morphologies and amplitudes in at least two of the three recorded Wilson-like leads. Despite recording with a bipolar smartwatch device, morphology of all six leads was identical to standard 12-lead ECG. In two patients with acute anterior myocardial infarction, all three cardiologists recognized the ST-elevations in Wilson-like leads and assumed an occluded left anterior descending coronary artery correctly. Conclusion: Consecutive recording of six single-lead ECGs including Einthoven and Wilson-like leads by a smartwatch is feasible with good ECG signal quality. Thus, this simulated six-lead smartwatch ECG may be useable for the detection of cardiac diseases necessitating more than one ECG lead like myocardial ischemia or more complex cardia arrhythmias.

Background The use of wrist worn wearable fitness trackers has been growing rapidly over the last decade. The growing popularity can be partly attributed to the improvements in technology, making activity trackers more affordable, comfortable and convenient for use in different fitness and environmental applications. Fitness trackers typically monitor activity level, track steps, distance, heart rate (HR), sleep, peripheral capillary oxygen saturation and more, as the technology continuously is advancing. In terms of measuring HR, photoplethysmography (PPG) is a relatively new technology utilised in wearables. PPG estimates HR through an optical technique that monitors changes in blood volume beneath the skin. With these new products becoming available it is important that the validity of these devices be evaluated. Therefore, the aim of this study was to assess the validity of the Polar Vantage M (PVM) watch to measure HR compared to medical grade ECG on a healthy population during a range of treadmill exercise intensities. Methods A total of 30 healthy participants (n = 17 males, n = 13 females) were recruited for this study. The validity of the PVM watch to measure HR was compared against the gold standard 5-lead ECG. The study was conducted on 2 separate testing days with 24–48 h between sessions. Participants completed the Bruce Treadmill Protocol, and HR was measured every 30 s. Validation of the PVM watch in comparison to the ECG was measured with an Intraclass Correlation Coefficient (ICC) and associated 95% confidence intervals (CI) and levels of agreement were identified with Bland–Altman plots with 90% limits of agreement. Linear regression analysis was performed to calculate the value of r2 computing the variation of HR obtained by the PVM watch and ECG. Results In total, 30 participants completed the protocol, with data from 28 participants utilised for statistical analysis (16 males, 14 females, 26.10 ± 3.39 years, height 52.36 m ± 7.40 cm, mass 73.59 ± 11.90 kg). A strong and significant correlation was found between the PVM watch and ECG, demonstrating good criterion validity (p < 0.05, r2 = 0.87). Good validity was seen for day 1 and day 2 for stage 0 (ICC = 0.83; 95% CI [0.63–0.92], ICC = 0.74; 95% CI [0.37–0.88]), stage 1 (ICC = 0.78; 95% CI [0.52–0.90], ICC = 0.88; 95% CI [0.74–0.95]), and stage 2 (ICC = 0.88; 95% CI [0.73–0.94], ICC = 0.80; 95% CI [0.40–0.92]). Poor validity was demonstrated on day 1 and day 2 for stages 3–5 (ICC < 0.50). Conclusion This study revealed that the PVM watch had a strong correlation with the ECG throughout the entire Bruce Protocol, however the level of agreement (LoA) becomes widely dispersed as exercise intensities increased. Due to the large LoA between the ECG and PVM watch, it is not advisable to use this device in clinical populations in which accurate HR measures are essential for patient safety; however, the watch maybe used in settings where less accurate HR is not critical to an individual’s safety while exercising.

Based on one simulated skin-electrode electrochemical interface, some electrochemical characteristics based on skin-electrode contact pressure (SECP) for dry biomedical electrodes were analysed and applied in this research. First, 14 electrochemical characteristics including 2 static impedance (SI) characteristics, 11 alternating current impedance (ACI) characteristics and one polarization voltage (PV), and 4 SECP characteristics were extracted in one electrochemical evaluation platform, and their correlation trends were statistically analysed. Second, dry biomedical electrode samples developed by the company and the laboratory, including textile electrodes, Apple watch, AMAZFIT rice health bracelet 1S, and stainless steel electrodes, were placed horizontally and vertically on the “skin” surface of the electrochemical evaluation platform, whose polarization voltages were quantitatively analysed. Third, electrocardiogram (ECG) collection circuits based on an impedance transformation (IT) circuit for textile electrodes were designed, and a wearable ECG acquisition device was designed, which could obtain complete ECG signals. Experimental results showed SECP characteristics for dry electrodes had good correlations with static impedance and ACI characteristics and the better correlation values among 2-10 Hz. In addition, polarization voltages in vertical state were smaller in horizontal state for dry biomedical electrodes, and polarization voltage of electrode pair (PVEP) values for Apple watch bottom was always smaller than ones for Apple watch crown and LMF-2 textile electrode. And the skin-electrode contact impedance of IT textile electrodes was less than the traditional textile electrodes.

Background Wearable devices with photoplethysmography (PPG) technology can be useful for detecting paroxysmal atrial fibrillation (AF), which often goes uncaptured despite being a leading cause of stroke. Objective This study is the first part of a 2-phase study that aimed at developing a method for immediate detection of paroxysmal AF using PPG-integrated wearable devices. In this study, the diagnostic performance of 2 major smart watches, Apple Watch Series 3 and Fitbit (FBT) Charge HR Wireless Activity Wristband, each equipped with a PPG sensor, was compared, and the pulse rate data outputted from those devices were analyzed for precision and accuracy in reference to the heart rate data from electrocardiography (ECG) during AF. Methods A total of 40 subjects from patients who underwent cardiac surgery at a single center between September 2017 and March 2018 were monitored for postoperative AF using telemetric ECG and PPG devices. AF was diagnosed using a 12-lead ECG by qualified physicians. Each subject was given a pair of smart watches, Apple Watch and FBT, for simultaneous pulse rate monitoring. The heart rate of all subjects was also recorded on the telemetry system. Time series pulse rate trends and heart rate trends were created and analyzed for trend pattern similarities. Those trend data were then used to determine the accuracy of PPG-based pulse rate measurements in reference to ECG-based heart rate measurements during AF. Results Of the 20 AF events in group FBT, 6 (30%) showed a moderate or higher correlation (cross-correlation function>0.40) between pulse rate trend patterns and heart rate trend patterns. Of the 16 AF events in group Apple Watch (workout [W] mode), 12 (75%) showed a moderate or higher correlation between the 2 trend patterns. Linear regression analyses also showed a significant correlation between the pulse rates and the heart rates during AF in the subjects with Apple Watch. This correlation was not observed with FBT. The regression formula for Apple Watch W mode and FBT was X=14.203 + 0.841Y and X=58.225 + 0.228Y, respectively (where X denotes the mean of all average pulse rates during AF and Y denotes the mean of all corresponding average heart rates during AF), and the coefficient of determination (R2) was 0.685 and 0.057, respectively (P<.001 and .29, respectively). Conclusions In this validation study, the detection precision of AF and measurement accuracy during AF were both better with Apple Watch W mode than with FBT.

IntroductionPersonal digital devices that provide health information, such as the Apple Watch, have developed an increasing array of cardiopulmonary tracking features which have received regulatory clearance and are directly marketed to consumers. Despite their widespread and increasing use, data about the impact of personal digital device use on patient-reported outcomes and healthcare utilisation are sparse. Among a population of patients with atrial fibrillation and/or atrial flutter undergoing cardioversion, our primary aim is to determine the impact of the heart rate measurement, irregular rhythm notification, and ECG features of the Apple Watch on quality of life and healthcare utilisation.Methods and analysisWe are conducting a prospective, open-label multicentre pragmatic randomised clinical trial, leveraging a unique patient-centred health data sharing platform for enrolment and follow-up. A total of 150 patients undergoing cardioversion for atrial fibrillation or atrial flutter will be randomised 1:1 to receive the Apple Watch Series 6 or Withings Move at the time of cardioversion. The primary outcome is the difference in the Atrial Fibrillation Effect on QualiTy-of-life global score at 6 months postcardioversion. Secondary outcomes include inpatient and outpatient healthcare utilisation. Additional secondary outcomes include a comparison of the Apple Watch ECG and pulse oximeter features with gold-standard data obtained in routine clinical care settings.Ethics and disseminationThe Institutional Review Boards at Yale University, Mayo Clinic, and Duke University Health System have approved the trial protocol. This trial will provide important data to policymakers, clinicians and patients about the impact of the heart rate, irregular rhythm notification, and ECG features of widely used personal digital devices on patient quality of life and healthcare utilisation. Findings will be disseminated to study participants, at professional society meetings and in peer-reviewed journals.Trial registration numberNCT04468321

The Apple Watch is capable of recording single-lead electrocardiograms (ECGs). To incorporate such devices in routine medical care, the reliability of such devices to obtain precordial leads needs to be validated. The purpose of this study was to assess the feasibility and reliability of a smartwatch (SW) to obtain precordial leads compared to standard ECGs. We included 100 participants (62 male, aged 62.8 ± 13.1 years) with sinus rhythm and recorded a standard 12-lead ECG and the precordial leads with the Apple Watch. The ECGs were quantitively compared. A total of 98 patients were able to record precordial leads without assistance. A strong correlation was observed between the amplitude of the standard and SW-ECGs’ waves, in terms of P waves, QRS-complexes, and T waves (all p-values < 0.01). A significant correlation was observed between the two methods regarding the duration of the ECG waves (all p-values < 0.01). Assessment of polarity showed a significant and a strong concordance between the ECGs’ waves in all six leads (91–100%, all p-values < 0.001). In conclusion, 98% of patients were able to record precordial leads using a SW without assistance. The SW is feasible and reliable for obtaining valid precordial-lead ECG recordings as a validated alternative to a standard ECG.

In the past years, utilization of ECG for verification and identification in biometry is investigated. The topic is investigated in this thesis. Recordings from ECG ID database from PhysioNet and our own ECG recordings recorded using Apple Watch 4 are used for training and testing this method. Many of the existing methods have proven the possibility of using ECG for biometry, however they were using clinical ECG devices. This thesis investigates using recordings from wearable devices, specifically smart watch. 16 features are extracted from ECG recordings and a random forest classifier is used for verification and identification. The features include time intervals between fiducial points, voltage difference between fiducial points and PR intervals variability in a recording. The average performance of verification model of 14 people is TRR 96,19 %, TAR 84,25 %.

Thesis (MPhil)--Stellenbosch University, 2015.
ENGLISH ABSTRACT: About half a million students matriculate from South African high schools each year, with limited environmental education and an underdeveloped capacity to live sustainable lives. This does not seem to be the case in some other parts of the world, where many high school students appear to be receiving education that is relevant to the socio-ecological crisis. The rationale of this thesis was to understand this phenomenon and explore what could be done to improve the situation for South African teenagers. This was a desktop study based upon systematic literature review methodology. The primary research objectives were to describe the local context of the study, explore emerging environmental education theoretical themes and detail a number of practical initiatives from around the world. The research process culminated in the fourth objective, which was to consolidate the work into key learnings for South Africa, with particular reference to South African teenagers. A backdrop to environmental education was provided that included a discussion on the global socio-ecological crisis, development and sustainable development in South Africa. The definition and use of the term “environmental education” was justified. In this instance, it is an inclusive definition that incorporates eco-literacy, ecological learning and education for sustainability. In addition to this, a brief comparative history of sustainable development and environmental education has been tabulated. Key theoretical themes in environmental education cluster around the centrality of place. Six themes are presented, namely space and place, trans-national education and third-culture kids, claims of transformation, principles of environmental education, institutional innovation, and the sustainability researcher. Three kinds of practical initiatives emerged in the literature review. These are “green fields” environmental education (brand new institutions), “moving train” environmental education (adaption of existing organisations) and “plug-in” environmental education. Eight initiatives are described, providing examples for all three of these groups. The key learnings for environmental education in South Africa and South African teenagers conclude this thesis. Among other key learnings, the value of the radical perspective is presented, as well as the benefit of perceiving environmental education through different lenses, including a historical one. The link between environmental education and food is explored. It is suggested that the theory and praxis of place-based education exerts a gravitational pull on many aspects of this work. It seems that place-based education provides a “holding space” for environmental education in South Africa, and a starting point for future research or practical application.
AFRIKAANSE OPSOMMING: Ongeveer ’n halfmiljoen studente matrikuleer jaarliks aan Suid-Afrikaanse hoërskole. Hierdie leerders beskik oor beperkte omgewingsopvoeding en ’n onderontwikkelde vermoë om volhoubare lewens te lei. Dít blyk nie die geval te wees in ander wêrelddele nie, waar baie hoërskoolleerders oënskynlik onderrig ontvang wat met die sosio-ekologiese krisis verband hou. Die beweegrede vir hierdie tesis was om hierdie verskynsel te verstaan en te bepaal wat gedoen kan word om die stand van sake vir Suid-Afrikaanse tieners te verbeter. Die navorsing het bestaan uit ’n lessenaarstudie op grond van ’n stelselmatige literatuuroorsig. Die hoofnavorsingsdoelwitte was om die plaaslike konteks van die studie te beskryf, ontluikende teoretiese temas op omgewingsopvoedkundige gebied te verken, en ’n aantal praktiese inisiatiewe van oor die hele wêreld te beskryf. Die navorsingsproses het uitgeloop op die vierde doelwit, naamlik om die studieresultate in kernlesse vir Suid-Afrika, bepaald met verwysing na Suid-Afrikaanse tieners, te verwerk. Eerstens word die agtergrond van omgewingsopvoeding geskets, wat onder meer bestaan uit ’n bespreking van die wêreldwye sosio-ekologiese krisis sowel as ontwikkeling en volhoubare ontwikkeling in Suid-Afrika. Die omskrywing en gebruik van die term ‘omgewingsopvoeding’ word ook geregverdig. In hierdie geval word die term inklusief gebruik om ook na eko-geletterdheid, ekologiese leer en onderwys vir volhoubaarheid te verwys. Daarbenewens bied die studie ’n bondige vergelykende geskiedenis van volhoubare ontwikkeling en omgewingsopvoeding in tabelvorm. Die vernaamste teoretiese temas op omgewingsopvoedkundige gebied draai om die kernrol van plek. Ses temas word aangebied, naamlik ruimte en plek, transnasionale onderwys en derdekultuurkinders, bewerings van transformasie, beginsels van omgewingsopvoeding, institusionele innovasie, en die volhoubaarheidsnavorser. Drie soorte praktiese inisiatiewe het uit die literatuuroorsig na vore getree, naamlik “braakland”-omgewingsopvoeding (splinternuwe instellings), “bewegende trein”-omgewingsopvoeding (aanpassing van bestaande organisasies) en “inprop”-omgewingsopvoeding. Agt inisiatiewe word beskryf, wat voorbeelde van ál drie hierdie groepe bied. Die tesis bied ten slotte die belangrikste lesse vir omgewingsopvoeding in Suid-Afrika en vir Suid-Afrikaanse tieners aan. Dit sluit onder andere in die waarde van die radikale perspektief, sowel as die voordeel daarvan om omgewingsopvoeding deur verskillende lense, waaronder ’n historiese een, te beskou. Die koppeling tussen omgewingsopvoeding en voedsel word verken. Die studie kom tot die gevolgtrekking dat die teorie en praktyk van plekgebaseerde onderwys ’n soort ‘beweegruimte’ vir omgewingsopvoeding in Suid-Afrika, sowel as ’n wegspringplek vir toekomstige navorsing of praktiese toepassing, bied.

Medical data generated by wearables and smartphones can add value to health care and medical research. This also applies to the ECG data that is created with Apple Watch 4 or later. However, Apple currently does not provide an efficient solution for accessing and sharing ECG raw data in a standardized data format. Our method aims to provide a solution that enables patients to share their Apple Watch’s ECG data with any health care institution via an iPhone application. We achieved this by implementing a parser in Swift that converts the Apple Watch’s raw ECG data into a FHIR observation. Furthermore, we added the capability of transmitting these observations to a specified server and equipping it with the patient’s reference number. The result is a user-friendly iPhone application, enabling patients to share their Apple Watch’s ECG data in a widely known health data standard with minimal effort. This allows the personnel involved in the patient’s treatment to use data that was previously difficult to access for further analyses and processing. Our solution can facilitate research for new treatment methods, for example, utilizing the Apple Watch for continuous monitoring of heart activity and early detection of heart conditions.

The Internet of Things (IoT) is a huge deal all around the world. It can be used in a variety of fields, including industrial, healthcare, agriculture, and the environment. Due to a lack of interaction among patients and doctors in the past, correct diagnosis was difficult to come by, and fatality rates were high. They were incapable of dealing with epidemics and pandemics. The Internet of Medical Things (IoMT) was recently developed to better and improve the healthcare profession. IoMT is a medical gadget that allows for increased patient convenience, price healthcare treatments, improved medical therapies, and more customized care. Wearable gadgets have been on the rise, with several benefits in terms of keeping watch of vitals and healthcare, igniting the growth of the Internet of Medical Things (IoMT). It allows electronic technologies to collect, analyze, and send information to cloud systems. This allows you to examine the patient's health status at any time and from anywhere, including body temperature, pulse rate, hearing beats utilizing ECG sensors, temperature, pressure, and observation. Digital gadgets have been designed and are widely used as a result of these systems. Doctors may keep track of a patient's health status in real time and prescribe medicine, vitamins supplements, and healthcare advice to them through. IoMT aids in the detection of body changes such as the growth of irregular masses of undifferentiated cells, the recognition of neural disorders, the checking of diabetic patients' glucose levels, the detection of psychiatric conditions using heartbeat, the real-time tracking of chronic disease symptoms, the screening of internal organ dysfunction, and the monitoring of cardiac blocks that cause heart attacks. IoMT assisted doctors in identifying and diagnosing COVID-19-affected patients and assisting them in providing appropriate therapy remotely. Clinical decisions were made with the help of IoMT as Artificial Intelligence (AI), telemedicine, and sensor technologies advanced. In the context of smart cities, IoMT introduces a new issue in the healthcare sphere. This chapter provides an outline as to how IoMT operates and how it has improved the lives of many patients through the use of modern technologies. This also includes a design and overview of IoMT, as well as numerous activities in the health-care industry, pop-up technologies, and several IoMT case studies in medical applications. It also lays out the IoMT's cybersecurity rules and indicates issues which need to be tackled at the parliamentary and community sectors.

The expectation of the growing child is to develop the skills to mature into an individual that can eventually survive to cope independently in their environment. To do this, the child must develop skills in the key functional areas of gross motor, fine motor, and vision, speech–language, and social. The acquisition of these skills is sequential with age. There is variability in the time it takes to acquire skills and their acquisition is affected by factors that are intrinsic (e.g. genetic) and extrinsic (e.g. antenatal factors, postnatal insults, exposure to stimulation, nutrition, etc.) to the child. Achieving an expected developmental skill is known as a developmental ‘milestone’. A delay in achieving a key milestone in a functional area by a certain limit of time that most children would be expected to have reached is called ‘developmental delay’. Delay in all key functional areas of development is known as ‘global developmental delay’. The paediatrician must have a good grasp of what degree of skill acquisition should be expected for the child’s chronological age, know when to watch and wait, and when to refer and investigate further. This is in order to identify problems early, treat any underlying cause, and instigate timely interventions to support the child to maximize their developmental potential.

Chapter 2 examines Forest’s work from the 1980s through the mid-1990s, which was characterized by greater emphasis on simulation, symbolism, and the sensory; a more varied “palette” of artistic production ranging from more conventional multimedia installations to ambitious attempts to create temporary alternative channels of networked mass communication; and a series of conceptual experiments in metacommunication as defined in the Aesthetics of Communication movement. Works discussed in Chapter 2 include The Territory of the Square Meter (1980), The Stock Exchange of the Imaginary (1982), Here and Now (1983), Press Conference of Babel (1983), Learn How to Watch TV with Your Radio (1984), In Search of Julia Margaret Cameron (1988), The Electronic Bible and the Gulf War (1991), Telephonic Faucet (1992), and The Watchtowers of Peace (1993). Chapter 2 also discusses Forest’s greater interest in ecological themes, the ramifications of globalization, and more explicitly political subjects (e.g., the collapse of Communist regimes in Eastern Europe, the Gulf War, and the Yugoslav Wars) in the late 80s and early 90s.

Mental health problems are estimated to affect one in four people each year in the UK, making mental illness one of the commonest presentations to GP surgeries, outpatient clinics, and Emergency Departments. Yet many doctors and medical students feel uncertain about how to approach patients with a psychiatric disorder. The key to becoming a good psychiatrist lies in the clinical interview. There are few physical signs or investigations that allow doctors to diagnose psychiatric illness, so a detailed history and mental state examination are important. As a psychiatrist, you are in the privileged position of having patients tell you their personal stories, and the skill is in listening attentively and asking relevant questions to help to clarify parts of the story. The best way to practise these techniques is to watch experienced clinicians at work and to interview patients yourself. Obviously diagnosis is important, so you need to be aware of the types of symptoms that fit with each type of disorder, as well as the medical conditions that may mimic psychiatric illness. Investigations may be necessary to rule out other diseases, and you need to be able to request these appropriately. Psychiatrists have access to a range of treatments—medical (e.g. antidepressants), psychological (e.g. cognitive behavioural therapy), and physical (e.g. electroconvulsive therapy)—and you need to know which ones to recommend. Most of these treatments are delivered in conjunction with the multidisciplinary team, so you should be clear about the roles of each team member. Finally, there is overlap between psychiatry and the law, which can raise interesting ethical issues. It is sometimes necessary to treat a person against their will, for the safety of that person or others, so you need to know about mental health law. Psychiatrists are also often requested to provide a second opinion in difficult capacity assessments.

Predators are extremely effective agents of selection. After all, if an individual member of a prey species does not survive long enough to reproduce, it will have lost its chance (kin selection considerations apart) to bequeath its genes to future generations. It is not surprising, therefore, that many cases of population difference have been attributed to geographic variation in risk. These population differences can take a variety of forms and may, for example, involve modifications to morphology or to life-history traits. The correlation between armor and predation in the three-spined stickleback, Gasterosteus aculeatus, is one case that has been well documented (see Reimchen 1994 for a review and discussion), while another is the association between reproductive allotment and risk (Reznick and Endler 1982) and male color pattern and risk (Endler 1980) in the Trinidadian guppy, Poecilia reticulata. However, such adaptations can be futile if they are not accompanied by effective antipredator behavior. For instance, a cryptic color pattern confers no advantage if its holder chooses the “wrong” background or behaves in a conspicuous manner. Behavior is also flexible in a way that life histories or morphology may not be, and it allows moment-to-moment changes in response as risk increases or decreases. Because it is such an important weapon in the evolutionary arms race, antipredator behavior provides important insights into the causes and consequences of natural selection. Some of the best examples of geographically variable antipredator responses occur in populations of freshwater fish (see, e.g., Bell and Foster 1994). The predation regime of these populations is relatively easy to classify—at least in terms of the presence and absence of predatory species—and the distribution of key predators can explain much of the documented variation in antipredator behavior (see p. 140). Covariance in predation regime and antipredator responses is compelling evidence for natural selection. Moreover, because predation regimes can change (or be manipulated) over relatively short periods of time, there is an opportunity to record heritable changes in antipredator responses—in other words, to watch evolution in action.

This paper investigates the proper synchronization of sketch data and cognitive states in a multi-modal CAD interface. In a series of experiments, 5 subjects were instructed to watch and then explain 6 mechanical mechanisms by sketching them on a touch based screen. Simultaneously, subject’s brain waves were recorded in terms of electroencephalogram (EEG) signals from 9 locations on the scalp. EEG signals were analyzed and translated into mental workload and cognitive state. A dynamic time window was then constructed to align these features with sketch features such that the combination of two modalities maximizes the classification of gesture from non-gesture strokes. Quadratic Discriminant Analysis (QDA) was used as classification method. Our experimental results show that the best temporal alignment for workload and sketch analysis starts from 30% time lag with previous stroke and ends before 30% time lag with next stroke.

ntracardiac echocardiography (ICE) catheter, known to have a strong ability to visualize cardiac structures and blood ﬂow from within the heart, is now being favorably used in cardiac catheterization and electrophysiology as an advanced imaging approach. However, clinicians require substantial training and experience to become comfortable with steering the catheter to localize and measure the area of treatment to watch for complications while device catheters are deployed in another access. Thus, it is reasonable that a robotic-assist system to hold and actively manipulate the ICE catheter could ease the workload of the physician. There exist commercially-available robotic systems [1] and research prototypes [2, 3] for ICE catheter manipulation. They all use existing commercially available ICE catheters (e.g. ACUSON AcuNav ICE catheter family, Siemens Healthineers) based on multiple tendon-sheath mechanism (TSM). To motorize the existing TSM-based ICE catheter, the actuators interface with the outer handle knobs to manip- ulate four internal tendons. However, in practice, the actua- tors are located at a sterile, safe place far away from the ICE handle [3]. Thus, to interface with knobs, there exist multi- ple coupled gear structures between two, leading to a highly nonlinear behavior (e.g. various slack, elasticity) alongside hysteresis phenomena in TSM [2]. Since ICE catheters are designed for single use, the expen- sive actuators need to be located in a safe place so as to be reusable. Moreover, these actuators should interface as di- rectly as possible with the tendons for accurate tip controls. In this paper, we introduce a separable ICE catheter robot with four tendon actuation: one part reusable and another disposable. Moreover, we propose a practical model and cal- ibration method for our proposed mechanism so that four tendons are actuated simultaneously allowing for precise tip control and mitigating issues with conventional devices such as dead-zone and hysteresis with simple linear compensa- tion. We consider an open-loop controller since many avail- able ICE catheters are used without position-tracking sen- sors at the tip due to costs and single use.
