Human Electroencephalogram

The visual design elements and principles (VDEPs) can trigger behavioural changes and emotions in the viewer, but their effects on brain activity are not clearly understood. In this paper, we explore the relationships between brain activity and colour (cold/warm), light (dark/bright), movement (fast/slow), and balance (symmetrical/asymmetrical) VDEPs. We used the public DEAP dataset with the electroencephalogram signals of 32 participants recorded while watching music videos. The characteristic VDEPs for each second of the videos were manually tagged for by a team of two visual communication experts. Results show that variations in the light/value, rhythm/movement, and balance in the music video sequences produce a statistically significant effect over the mean absolute power of the Delta, Theta, Alpha, Beta, and Gamma EEG bands (p < 0.05). Furthermore, we trained a Convolutional Neural Network that successfully predicts the VDEP of a video fragment solely by the EEG signal of the viewer with an accuracy ranging from 0.7447 for Colour VDEP to 0.9685 for Movement VDEP. Our work shows evidence that VDEPs affect brain activity in a variety of distinguishable ways and that a deep learning classifier can infer visual VDEP properties of the videos from EEG activity.

Abstract. Music video (MV) content is frequently measured using researcher descriptions. This study examines subjective or viewers’ notions of sex and violence. 168 university students watched 9 mainstream MVs. Incidence counts of sex and violence involve more mediating factors than ratings. High incidents are associated with older viewers, higher scores for Expressivity, lower scores for Instrumentality, and with video orders beginning with high sex and violence. Ratings of sex and violence are associated with older viewers and lower scores for Instrumentality. For sex MVs, inexperienced viewers reported higher incidents and ratings. Because MVs tend to be sexier but less violent than TV and film, viewers may also use comparative media standards to evaluate emotional content MVs.

The Brain

Over 20 years ago, Watt and Hameroff (1987 ) suggested that consciousness may be described as a manifestation of deterministic chaos in the brain/mind. To analyze EEG-signal complexity, we used Higuchi’s fractal dimension in time domain and symbolic analysis methods. Our results of analysis of EEG-signals under anesthesia, during physiological sleep, and during epileptic seizures lead to a conclusion similar to that of Watt and Hameroff: Brain activity, measured by complexity of the EEG-signal, diminishes (becomes less chaotic) when consciousness is being “switched off”. So, consciousness may be described as a manifestation of deterministic chaos in the brain/mind.

(1) Background: As the literature analysis shows, cancer patients experience a variety of different needs. Each patient reacts differently to the hardships of the illness. Assessment of needs allows providing more effective support, relevant to every person’s individual experience, and is necessary for setting priorities for resource allocation, for planning and conducting holistic care, i.e., care designed to improve a patient’s quality of life in a significant way. (2) Patients and Methods: A population survey was conducted between 2018 and 2020. Cancer patients, as well as their caregivers, received an invitation to take part in the research, so their problems and needs could be assessed. (3) Results: The study involved 800 patients, 78% women and 22% men. 66% of the subjects were village residents, while 34%—city residents. The mean age of patients was 62 years, SD = 11.8. The patients received proper treatment within the public healthcare. The surveyed group of caregivers was 88% women and 12% men, 36% village residents and 64% city residents. Subjects were averagely 57 years old, SD 7.8. At the time of diagnosis, the subjects most often felt anxiety, despair, depression, feelings of helplessness (46%, 95% CI: 40–48). During illness and treatment, the subjects most often felt fatigued (79%, 95% CI: 70–80). Analysis of needs showed that 93% (95% CI: 89–97) of patients experienced a certain level of need for help in one or more aspects. (4) Conclusions: Patients diagnosed with cancer have a high level of unmet needs, especially in terms of psychological support and medical information. Their caregivers also experience needs and concerns regarding the disease. Caregivers should be made aware of the health consequences of cancer and consider appropriate supportive care for their loved ones.

Are political parties in young democracies responsive to the policy preferences of the public? Compared to extensive scholarship on party responsiveness in established democracies, research on party responsiveness in young democracies is limited. We argue that weaker programmatic party–voter linkages in post-communist democracies create incentives for parties to respond to their supporters rather than the more general electorate. Such responsiveness occurs in two ways. First, parties follow shifts in the mean position of their supporters. Second, drawing on the research on party–voter congruence, we argue that parties adjust their policy positions to eliminate previous incongruence between themselves and their supporters. Analyses based on a comprehensive dataset that uses expert surveys, parties’ manifestoes and election surveys to measure parties’ positions, and several cross-national and national surveys to measure voters’ preferences provide strong support for this argument.

Music Stimulus

People feel different emotions when listening to music on certain levels. Such feelings occur because the music stimuli causing reduced or increased brain activity and producing brainwave with specific characteristics. Results of research indicated that classical piano music can influence one’s emotional intelligent. By using Electroenchephalography (EEG) as a brainwave recording instrument, we can assess the effect of stimulation on the emotions generated through brain activity. This study aimed at developing a method that defines the effect of sound to brain activity using an EEG signal that can be used to identify one's emotion based on classical piano music stimulus reaction. Based on its frequency, this signal was the classified using DWT. To train Artificial Neural Network, some features were taken from the signal. This ANN research was carried out using the process of backpropagation

Background: Signage provides information and direction. It is important as a medium to show direction in offices and public buildings. It is more crucial for emergency services, specifically hospitals. Incomplete information and confusion of signage are among common issues being raised by the public to hospital management. Objective:This study is carried out to determine user height preferencesof Hospital Kajangs signage and to proposean appropriate height forits future signage. Approach: Thirty five respondents (20male and 15 female) participated in this study. They are aged between 18 to 60 years old with the mean of age at39years old. Their stature height and eye-level height are measured using SECA Stable Stadiometer.They are asked to give a rating using 1-10 scaleon threequestions to measure their preferences towards the present signage.The studied signage is also measured using standard measuring tape. The data is analyzed using SPSS.Results:It is found that 25 respondents (71.43%) agree to say that the height of signage in Hospital Kajang is too highwhile10 of them (28.57%) disagree. The signage should be10.5 cm lower from present height in order to optimize its function for both groups. The proposed signage height should be 187.5 cmfrom the floor. Conclusion:The present signage in Hospital Kajang requires necessaryheight readjustment to satisfythe majority of its staffs and visitors. The improvement is vital to ensure the signage meet the directional purpose.

Purpose The purpose of this paper is to present an empirical study on the time needed to load and disburse cash using bill validators on slot machines and stand-alone cash dispensers in casinos in British Columbia under a Ticket In Ticket Out (TITO) system. Design/methodology/approach Testing took place over two days, using 18 machines. The results were extrapolated to estimate the approximate time required to process $1,000,000 with different average bill amounts in the cash mix and three different bill validator machines in common use. The average value per bill using the cash mix used by the public in the casino was $33.11 [standard error (SE) $2.11]. Findings The mean time/accepted note ranged from 4.12 to 9.65 s, depending on bill validator type. This implies that the time needed to load $1,000,000 onto credit slips using bill validators on slot machines ranges from 35 to 81 h, excluding rest breaks and other breaks. The time needed to redeem $1,000,000 is estimated to be 3 h. Practical/implications The implications of these finding for illicit actors to successfully launder large amounts of cash are discussed. Given the time needed to physically handle the cash, and other control systems currently in use in casinos in British Columbia, processing large amounts of cash using bill validators on slot machines would require a highly organized team that would find it difficult to elude detection. Originality/value The trial results provide a baseline estimate to be used going forward when investigating or proposing money laundering methodologies that include slot machines.

Chronic Problem

An aggressive logging becomes a chronic problem in Indonesia. There is an inappropriate paradigm in the understanding and treating of the environment, especially trees and forests. This article examines the discourse of nature conservation based on Balinese local wisdom as presented in visual cartoons of Bog-Bog magazine (No 10, Vol 10, 2012) which theme is tree. Information data taken from cartoon Bog-Bog magazine No. 10, analyzed by the theory of semiotics and supported by the theory of visual design elements. The pictures from the Bog-Bog cartoon show the artistic, critical and humorous efforts of the Bog-Bog cartoonists in constructing Balinese local discourse based on customs, belief, and Hindu religion in an important message of preserving the forest in particular and nature in general. Analysis shown that Bali has a number of local wisdom such as the sacred trust system of tree as one of the ecological messages for forest preservation. An example is the concept of palemahan in the Hindu philosophy of Tri Hita Karana which is important for the harmony of human relationship with nature as a source of prosperity. Bog-Bog cartoon successfully convey the nature conservation discourse based on Balinese local wisdom with the construction of humor, critical, and parody discourse.

ABSTRACT Objective To describe the profile of lawsuits related to drug requests filled at the Federal Justice of the State of Paraná. Methods A cross-sectional study, and the data were obtained through consulting the lawsuits at the online system of the Federal Justice of Paraná. Results Out of 347 lawsuits included in the study, 55% of plaintiffs were women, with a median age of 56 years. Oncology was the field with more requests (23.6%), and the highest mean costs. A wide variety of diseases and broad variety of requested drugs were found in the lawsuits. Approximately two-thirds of them were requested by the brand name, and the most often requested drugs were palivizumab and tiotropium bromide. Only 14.5% of the requested medicines were registered in the National Medication Register. The Public Defender’s Office filled actions in 89.6% of cases and all lawsuits had an interim relief. The mean time for approval was 35 days and 70% of requests were granted. Conclusion Oncology was the field with the highest demand for medicines at the Federal Justice of Paraná in 2014. A great variety of medications was requested. The Public Defender´s Office represented most lawsuits. All demands had an interim relief, and the majority of requests were granted, within an average of 35 days.
