Background With an increasing number of vehicles becoming autonomous,intelligent,and connected,paying attention to the future usage of car human-machine interface with these vehicles should become more relevant.Several studies have addressed car HMI but were less attentive to designing and implementing interactive glazing for every day(autonomous)driving contexts.Methods Reflecting on the literature,we describe an engineering psychology practice and the design of six novel future user scenarios,which envision the application of a specific set of augmented reality(AR)support user interactions.Additionally,we conduct evaluations on specific scenarios and experiential prototypes,which reveal that these AR scenarios aid the target user groups in experiencing a new type of interaction.The overall evaluation is positive with valuable assessment results and suggestions.Conclusions This study can interest applied psychology educators who aspire to teach how AR can be operationalized in a human-centered design process to students with minimal pre-existing expertise or minimal scientific knowledge in engineering psychology. 展开更多

Resilience is the psychological capability to recover from difficulties quickly.Healthcare professionals are especially vulnerable to job-related stress and burnout.Unitary Caring Science is the framework for Watson’s Human Caring Theory,providing a philosophy of practice in healthcare.With the high rates of clinician burnout and psychological issues,it will be significant to unify the human caring theory with research-informed psychological and neuroscience evidence to develop clinicians’resilience-building strategies.The purpose of this article is to introduce a Unitary Caring Science Resilience Model and explain the science behind the core strategies based on Unitary Caring Science philosophy and the psychological and neuroscience research.This model includes six strategies:Embracing loving-kindness for self and others;Nurturing interpersonal and intersubjective connections/relations;Deepening a creative use of self and sense of belonging;Balancing self-learning,self-awareness,and an evolved selfconsciousness;Valuing forgiveness and releasing negativity;Inspiring and maintaining faith-hope.The caring-theory guided resilience-building strategies are proven to alleviate the depletion of clinicians’energy and emotions.Healthcare practices are challenging but rewarding.Clinicians can be emotionally,psychologically,and physically exhausted if they always consider themselves‘giving’and‘doing’institutional tasks without a sense of purpose or fulfillment.The practice can be rewarding if it becomes more aligned with clinicians’value to serve humanity.Through the unitary caring science resilience strategies,clinicians can build resilience as an antidote to clinician burnout and depletion. 展开更多

World War I had brought great pain to people, old beliefs had been lost and new beliefs were badly-needed. On the road to discover new beliefs, therefore, the surrealism originated from so-called "surreal" and "super-reasonable" dreams became an attempt. As a leading brand of fashion and jeans, with its distinctive symbolic meaning Levi's is a typical symbol of American clothing. Much spiritual, cultural and artistic temperament was given to Levi as time changes, and Levi became a symbol of personality and rebellion ever since. This paper analyzed how designers of Levi applied the realism thinking in advertising design,and gave uniqueness and attraction to Levi's advertisement, based on which, the paper conducted a comprehensive theoretical research on Levi's design. 展开更多

The paper presents a design method that ensures the ingenuity of the product form as well as the whole and exact expression of user’s needs. The key idea is to establish an automatic design system which can transform the user’s language needs into the product features in real-time. A rifle was taken as a research instance and soldiers were chosen as evaluation customers. The theory of fuzzy set and semantic difference are adopted to evaluate the relationship between user’s needs and product features as well as their alternatives. FAHP (fuzzy analytic hierarchy process) is utilized to judge the user’s satisfactory forms. This method can also be applied to other product form designs. 展开更多

Frequent itemset mining is an essential problem in data mining and plays a key role in many data mining applications.However,users’personal privacy will be leaked in the mining process.In recent years,application of local differential privacy protection models to mine frequent itemsets is a relatively reliable and secure protection method.Local differential privacy means that users first perturb the original data and then send these data to the aggregator,preventing the aggregator from revealing the user’s private information.We propose a novel framework that implements frequent itemset mining under local differential privacy and is applicable to user’s multi-attribute.The main technique has bitmap encoding for converting the user’s original data into a binary string.It also includes how to choose the best perturbation algorithm for varying user attributes,and uses the frequent pattern tree(FP-tree)algorithm to mine frequent itemsets.Finally,we incorporate the threshold random response(TRR)algorithm in the framework and compare it with the existing algorithms,and demonstrate that the TRR algorithm has higher accuracy for mining frequent itemsets. 展开更多

Previous clinical trials have demonstrated the efficacy of yokukansan, a traditional Japanese medicine, for the treatment of behavioral and psychological symptoms of dementia (BPSD). However, less evidence is available for the treatment of BPSD with yokukansankachimpihange (YKSCH), which consists of yokukansan and two additional herbal ingredients. The present study was conducted to investigate the efficacy and safety of YKSCH for treating BPSD in patients with Alzheimer’s disease (AD). We enrolled outpatients with mild-to-moderate AD who exhibited BPSD and obtained a Neuropsychiatric Inventory (NPI) score of >3 including subscale scores for “agitation”, “anxiety”, “irritability”, and “sleep and night-time behavior change”. A daily YKSCH dose of 7.5 g was administered for 12 weeks with concomitant administration of anti-dementia medication. BPSD was evaluated using the NPI at baseline and every 4 weeks during the intervention. We also examined apathy using the Japanese translation of the Apathy Scale, the short version of the Japanese version of the Zarit Caregiver Burden Interview, and the Modified Crichton Rating Scale for Predicting Activities of Daily Living. Cognitive dysfunction was evaluated using the Mini Mental State Examination and the AD Assessment Scale-Cognitive (Japanese version). Five participants were enrolled. The NPI total score tended to decrease between the baseline and 8-week evaluations during the YKSCH intervention (Wilcoxon signed rank test, P = 0.063). In terms of the NPI subscale scores, “apathy”, “agitation”, “delusions”, and “sleep and night-time behavior change” decreased after the intervention in those who exhibited each symptom at baseline. There were no significant differences in the other scores examined. No serious adverse events were observed. YKSCH could ameliorate BPSD in patients with mild-to-moderate AD with agitation, anxiety, irritability, and sleep and night-time behavior change, and it was well-tolerated. 展开更多

Parkinson’s disease (PD) is a neurodegenerative disease mainly caused by motor disorders, mostly occurring in middle-aged and elderly people. The incidence of PD has been increasing year by year, and up to now, PD is still an incurable disease. However, more and more data show that early implementation of deep brain stimulation and early medical, psychological, social and other interventions can significantly improve the quality of life and prolong the survival time of patients with Parkinson’s disease (PD). Mental health guidance, cognitive behavioral intervention, psychogenic therapy and scientific nursing for PD patients may improve the functional recovery after Deep Brain Stimulation (DBS) for Parkinson’s disease. This paper discusses the nursing and psychological intervention methods of deep brain stimulation (DBS) implantation in patients with Parkinson’s disease (PD), aiming to scientifically discuss the clinical effect of nursing psychological intervention and improve the quality of life in patients with Parkinson’s disease. Basic nursing and psychological cognitive behavior intervention measures for PD patients can improve the daily activity ability of PD patients, improve the outcome of PD patients, and effectively improve the satisfaction of PD patients with nursing work, which has certain clinical promotion significance. 展开更多

Vygotsky (1896-1934) pursued the objective of reformulating psychological theory. His historical-cultural analysis of the "crisis in psychology" showed that, beyond contradictions between the two main methodological currents---"objective/explanatory" and "subjective/intuitive"--psychology is primarily influenced by its empirical-sensory foundations. This influence is actually at the origin of the disagreement since it maintains the obligation for the two currents to make reference to empirical-sensory data. Only a general model of the developing human being, assessed by its usefulness, will allow reorienting psychology towards a broader science. This would lead to a general theory of psychology, which could then facilitate the search for tools for an indirect method enabling it to go beyond empiricism. 展开更多

For telecommunication operators, how to improve the utilization of bandwidth resources is always a problem which worthy of study, nowadays, this issue has become more and more important, since the traffic load bursting in the mobile Internet. So the key to solving this problem is that we need to find a kind of traffic model to predict the traffic load that users need. According to the predicted traffic load to allocate bandwidth to each base station dynamically.But the traffic consumption behavior of a single base station is random, it is difficult to predict[ 1 ]. For this reason, we based on reality that, when the user moves, it may get traffic load from different base stations, therefore, there will have some kind of relationship between those base stations.We use this relationship to establish a kind of Spatial Collaborative Network.consequently, we make use of stability algorithm to divided those base station cluster into different communities, According to the traffic load usage rules which these communities indicated to us, we get a traffic model.At the same time, we studied bow to use this traffic model in the future networks to dynamically allocate bandwidth resources, then we propose a new kind of EPS architecture based on SDN, on this platform, we can deploy our strategy through it's programmable interface.Finally, we designed an experiment to test the performance of our dynamic strategy, and the result shows that our method enables bandwidth utilization has been greatly improved. 展开更多

To observe the differences in psychological status between Bell’s palsy (BP) patients and healthy subjects, and to examine the relationship between psychological factors and the severity of BP, we conducted a case-control, multi-center clinical investigation. A total of 695 subjects were assigned to the case group (n=355) and the control group (n=340). House–Brackmann grading system and Facial Disability Index (FDI) were adopted to assess the BP patients; Kessler Psychological Distress Scale (K10) and 16 Personality Factor (16PF) scale were employed to evaluate the psychological distress and personality profiles of all subjects. Two independent samples t test was used to compare the differences between cases and controls, and to compare the differences among different BP patients. Pearson correlation analysis was used to examine the relationship between psychological factors and severity of facial paralysis. The results showed that psychological distress (K10) in case group (27.09±5.80) was significantly higher than that in control group (13.43±3.02) (t=–37.219, P=0.000). The scores of personality factor Warmth (A), Openness to Change (Q1), Self-Reliance (Q2) were lower in cases than in the controls (P<0.01, P<0.05, P<0.05, respectively), whereas the scores of Sensitivity (I), Vigilance (L), Apprehension (O), and Tension (Q4) were significantly higher in cases than in the controls (P<0.05, P<0.01, P<0.01, P<0.01, respectively). In addition, the psychological distress was significantly higher in female patients, severe (HB score Ⅳ–Ⅵ) patients, and subacute (onset time 72–168 h) patients compared with that in male patients, mild (HB score Ⅰ–Ⅲ)patients, and acute (onset time≤72 h) patients (P<0.05). The scores of personality factor in female patients, severe patients, and subacute patients were also significantly different from male patients, mild patients, and acute patients (P<0.05). The result of Pearson correlation analysis showed that psychological factors (K10, personality A, F, L, N, O, Q4) were closely related to HB scores. We are led to conclude that the psychological status between BP patients and healthy people are different; psychological distress and personality factors are closely associated with severity of facial paralysis. 展开更多
