Kansei Analysis of Liquid Laundry Detergent Bottle's Shape and Packages Design
Authors: Kang Namgyu , Kaito Nishiya
Published: June 2022

Nowadays, there are various bottles and packages of liquid laundry detergents in Japan. Many companies have tried to create not only more powerful detergency of the products but also the new value of design in the laundry detergent bottle and package. And our lifestyle is changing like an increasing nuclear family and single life and enjoying a shopping using the internet in recent. Since selecting a detergent might be linked depending on such lifestyle, we need to survey the relationship between the design of detergents such as a bottle shape or package and the user's lifestyle. Therefore, we focused on the shape of bottles and packages of liquid laundry detergents in this study. Therefore, this study aims to clarify the difference in impressions of the bottle's shapes and packages of laundry liquid detergent based on Kansei engineering.So, we have experimented with ten bottles and packages using the ranking evaluation method to clarify the relationship between participants' decision to want to use bottles and the following items; 1) Luxury feeling level, 2) Easiness level to grip, 3) Fit feeling level to the laundry space, 4) Easiness level to store the bottle up, 5) Fleeing level of detergency power, and 6)Preference level to want to use. As a result, the item of "Preference level to want to use" had a stronger relationship with the bottle's packages of liquid laundry detergents than the bottle's shapes concerned with the usability of liquid laundry detergents. Even though the handle helps grip the bottles, participants preferred these bottles that do not have any handles with a luxury feel. Moreover, for the "Preference level to want to use," the Kansei factors of the bottle's shape, such as "Luxury feeling level" and "Fit feeling level to the laundry space," are more critical than the Usability factors, such as "Easiness level to grip" and "Easiness level to store up." Also, in the bottle packages situation, the item "Preference level to want to use" had a more substantial relationship with the item of "Luxury feeling level" than "Fleeing level of detergency power." This "Preference level to want to use" and packages differ depending on the participants' lifestyle, such as 'living style' and 'number of washes clothes per week.' For example, the participants who live alone want to use the bottle with a luxury feeling and easy to store. In contrast, the participants who live with family want to use the bottle with a luxury feeling, which fits their laundry space. These participants who live with family showed a similar tendency as the number of washes increased. Moreover, there are different characteristics in evaluating liquid laundry detergent depending on each one's lifestyle. Also, these results mean we need to survey more the condition of laundry space in Japan to propose a new bottle package design as future work.

In future autonomous cars, users, free from the primary task of driving, will have time and space to engage in other activities while traveling, such as reading a book, working on a laptop or watching a movie. Although the option for these activities are one of the great advantages of autonomous cars, this will also likely increase motion sickness (MS) inside the car. MS affects numerous individuals, and it occurs when the information received through the eyes differs from what is perceived by the body and the inner ear. Plus, MS can have an impact on the emotional component of the individuals experiencing it, making the experience of traveling in autonomous cars uncomfortable and difficult. Emotional design studies focus on the emotional response of individuals to a product or service. These studies typically employ self-report scales as assessment tools, such as SAM (Self-Assessment Manikin) and PrEmo (Product Emotion Measurement instrument). We present the first study measuring emotional responses to MS using both SAM and PrEmo scales. In our study, we induced MS by asking participants to watch a highly dynamic video of a first-person car trip. We also asked subjects to answer to SAM and PrEmo before and after the visualization of the video. Our results showed a change in the answers in time, that is, before vs. after the experience of MS. MS significantly altered individuals' emotional responses, worsening their condition. These results support the need for studies that reduce MS to improve the experience and well-being of individuals in autonomous cars.

Published: June 2022

A method of human-computer interface color design based on aesthetic feeling is proposed, which provides a basis for the design practice in accordance with users' aesthetic preference. Taking the mobile interactive terminal interface of intangible cultural heritage display as an example, the color matching of Cloisonne, a traditional Chinese craft, was selected as the primary color, and the colors were extracted by k-means clustering algorithm to form four groups of color matching samples. Secondly, the interface element model is constructed, and the matching relationship between color matching samples and interface interaction elements is established and applied. Thirdly, the network text analysis method ROST was used to extract the perceptual image semantics of interfaces, and the four groups of interfaces were subjectively evaluated to obtain the optimal scheme and verify the effectiveness of the proposed color matching method. The results show that the aesthetically driven color design method is beneficial to improve the information transfer and aesthetic experience of human-computer interaction, and promote the creative transformation of intangible cultural heritage in digital mobile media.Keywords: Human-computer Interface, Ergonomics Design, Color Design Method, Perceptual Image, Aesthetic Evaluation
Prediction of health screening data with personal uncertainty using bayesian neural networks
Authors: Osawa Yusuke , Tawata Shohei , Watanuki Keiichi , Kaede Kazunori
Published: June 2022

In Japan, a specific health checkup has been conducted for people aged 40 and over since 2008. In the specific health checkup, public health nurses and dietitians provide health guidance according to the level of health based on the results of test values and questionnaire items. However, the content of the guidance for lifestyle improvement varies depending on the experience and judgment of the instructor. And the guidance is based only on the health checkup result report. Therefore, the evidence for lifestyle improvement is weak and does not lead to actual lifestyle improvement.In order to solve this problem, we have developed a system that predicts future test values based on past test values. In our previous research, we constructed a highly accurate model for predicting the next year's test values based on the past's health checkup test using a multichannel deep convolutional neural network, which is a type of machine learning. In addition, the features as the basis for the model's predictions were analyzed by sensitivity analysis in order to evaluate the validity of the predictions. However, there are the cases that some examinees may suddenly change their lifestyles, even if similar trends were observed in the previous year. In addition, even if the same health guidance was given in the previous year, the awareness of lifestyle improvement differ among individuals. In addition, even if the same health guidance was given in the previous year, the awareness of lifestyle improvement differ among individuals. The questionnaire includes items that ask about the awareness of lifestyle improvement, and these items have variations in the actual degree of lifestyle improvement among individuals. Thus, there is uncertainty in the prediction of test values for each examinee. In order to be convincing and safe, it is necessary considering the uncertainty of the previous year's data in predicting test values. The purpose of this study is to predict the test value considering the uncertainty of the test value due to the awareness of lifestyle improvement among examinees. A bayesian neural network (BNN) is a network that considers the weights in a neural network as random variables generated based on a certain probability distribution. We constructed a highly accurate BNN prediction model using the health checkup results concluding the basic data (age and sex), the test values of the past two years, and the results of questionnaire items as inputs, and the test values of the next year as outputs. The incidence of lifestyle diseases are predicted based on these diagnostic criteria using the BNN model outputs. In the future, we will compare the prediction of disease onset by the BNN model with that by the conventional neural network model using the actual diagnosis results of lifestyle diseases, and examine the explanatory of the two models.

Due to the shortage of labor force in Japan, skill transfer and training education are becoming increasingly important in the manufacturing industry. In recent years, virtual reality (VR) technology has attracted attention in work-related training, enabling simplified training, but there is a problem that human and time resources cannot be sufficiently allocated to training due to a lack of educators and an immature training system. In this study, we developed a method to automatically recognize tasks and actions to improve the efficiency of education and training. To recognize tasks and actions, we adopted a deep learning model that can recognize actions from videos in time series, and we pre-trained the model on a large open-source dataset. We evaluated the performance of the model on unlearned procedures and people by preparing a dataset with three different procedures and 10 participants. The overall validation metrics all exceeded 90%. Specifically, results of more than 90% were achieved for unlearned people, but a drop of more than 5% was observed for all unlearned procedures, suggesting that issues must be addressed for application to task training.

Authors: Siyi Zhu , Shang Huifang , Wang Chuanshun
Published: June 2022

Background: In recent years, the concept of medical treatment in China has gradually developed from traditional "therapeutic mode" to "preventive health care", and the demands of patients are more diversified. Then the social attribute of hospitals is improved, and the proportion of non-medical space in hospitals is significantly increased. As the main public space of the hospital, the medical main street connects various functional zones and has a variety of attributes such as circulation system, relaxation, social contact and commercial services. It is a place where patients mainly gather and stay for a long time in the hospital. Significance: Providing supportive design for medical space can effectively alleviate the pressure and tension of patients in the process of medical treatment, bring more comfortable medical experience, help to establish a safer, more efficient and humanized medical environment, and play a positive role in patient health. Methods: Therefore, from the perspective of supportive design theory, this paper studies the relevant literature of medical space, as well as the field research and analysis of the newly built medical main street in China. Aims: To explore the development tendency of medical main street design. Conclusion: Through the research, it is found that in the actual cases, designers pay more attention to the circulation system, way-finding system, visibility in the central area and space color of the medical main street, in order to help improve the medical efficiency. In the paper, researchers also pay close attention to the circulation system, way-finding system and visibility in the central area. It is considered that easy access to the required place is the main factor to reduce the anxiety in patients. Meanwhile, the researchers also take natural lighting, commercial services and the choice of social contact or privacy as important indicators of the medical main street, and believe that the safe, comfortable and energetic space will help patients feel respected, so as to reduce negative emotions. Viewpoint: Therefore, this paper believes that as the basic demand, the future design of medical main street will take convenience as the main indicator. On this basis, the service function have also been gradually incorporated into the evaluation system of medical main street design, and will be the main direction of future research, so as to improve the support of medical space and gradually build a safe, healthy, efficient and dynamic medical community.

Chronic sick leaves in Europe are strongly related to mental health issues. Ecological Momentary Assessment (EMA) enables collecting data on mental health, but it is challenging to implement in fast-paced and controlled work environments. We describe the design of an EMA device for workers in a garment factory, along with individual data visualisation, which were evaluated in naturalistic setting with eight workers for one week during work hours to understand whether and how participants would engage with the device. Participants easily used the device at work and appropriated it in different ways, mainly by extending its declared function. Confrontation with individual data visualisations led to episodes of self-discovery and participants suggested extending the use of the device to more operators to get a picture of workers’ wellbeing. However, participants expressed doubts about data validity.
Evaluation of Attention Guidance through Visual Subthreshold Stimulus Using a HMD
Authors: Maeda Yusuke , Watanuki Keiichi , Kaede Kazunori
Published: June 2022

Attention guidance is used as a means of conveying important information. Many attention guides use colors or color gradations that stand out from the surrounding environment, such as signs, or directional shapes such as arrows. In the past, some studies have used directional events such as the gaze of others, optical flow, and optical illusions to guide attention. However, such stimulus presentation methods may cause annoyance and discomfort to people because of their high degree of stimulation. For example, when an alert is displayed for a hazard that appears probabilistically when driving a car, it often causes annoyance and discomfort to the driver when the hazard does not appear. In this paper, we propose a new method of alerting the driver by affecting the unconscious region of the brain. In past research, it has been reported that displaying an object in the frame before the visual search task induced attention and shortened the reaction time. In addition, it has been reported that by displaying a short cue during eye movement, the gaze moved in the direction of the cue. The purpose of this study is to evaluate the validity of attentional guidance by presenting such visual subthreshold stimuli. The participants wore a head-mounted display and performed a visual search task in which they had to find and answer one search object different from the others among eight search objects. The time from the start of the visual search task to the finding of the target object and the trajectory of the gaze during the search were used as evaluation indicators. Ten healthy males in their twenties (22.8 years old ± 1.72 years old) with corrected eyesight cooperated in the experiment. The objects to be searched were placed 1 m away from the participants and at 30° to the up, down left, right. A masked image was inserted before the visual search task, and one of the explorers could be seen one frame (Approx. 0.01ms) before the visual search task, which was used as a visual subthreshold stimulus. These cues could be either consistent with or different from the search object to be found. The results of this experiment showed that there was no significant difference in mean reaction time between the three conditions: when the cue matched or differed from the search object to be found, and when the cue was not presented. However, there was a tendency that the position at which the participants first started their search was closer to the location of the cue. This suggests that the threshold stimulus has an effect of inducing attention, but there was no tendency to draw attention strongly. In addition, the speed of recognition was large for some participants, and cues were recognized in some cases. The reason for this result is thought to be the contrast ratio between the cue and the mask image and the presentation position of the cue. Therefore, it is necessary to examine the contrast ratio and the presentation position of the cue for each experimental collaborator.

This research aims to provide tourism information on the healing effects of forest bathing and power spots in response to the health consciousness of the After Corona and With Corona era. For this purpose, we will elucidate the following questions: "What exactly are the effects of forest bathing, and what brings about the healing effects? Specifically, by collecting and analyzing information that links brain waves and GPS location information, it will be possible to provide pinpoint information on which places and how much of a relaxing effect they have, such as where to go near a waterfall or under a huge tree. We will also elucidate the factors that bring about the relaxation effect and examine the possibility of reproducing the relaxation effect. Based on the results of these studies, we will improve the functions and performance of the Nikko Senjogahara guide application that we have been developing for seven years. Regarding measuring the effects of forest bathing, measuring the amount of cortisol at the beginning and the end of the bath is common. However, in that case, we can know the effects as an area; however, it is not easy to provide pinpoint information on which place and how much relaxation is good, for example, near a waterfall here or there, or under this huge tree. In addition, research on the default mode network, the idle state of the brain, has been progressing in recent years. When relaxing by taking a forest bath and paying attention to the inner world, a state of mind-wandering (thinking about many things in a daze) is created, which is expected to activate the default mode network. As a result, it is expected that memories in various parts of the brain under the conscious mind will be connected, and the brain will be in a state where creativity can be easily exercised. Suppose forest bathing or strolling promotes the activation state of the default mode network. In that case, we can measure the effect by continuously measuring EEG and know if there is any difference depending on the location. Once the location can be identified, it is possible to know which of the five senses of information are effective at that location, whether it is auditory, olfactory, or tactile. From this, we can expect to know the elements, such as the sound of water, wind, leaves rubbing, the scent of the trees, and the spray of wind and water, that bring about the effects of forest bathing. For that purpose, we have been developing a wearable EEG sensor with a startup. From the test on our campus using that EEG sensor, we had an interesting result. For example, α wave was increased around a fountain, and β wave was increased when taking photos. In 2022, we are planning to start collecting and analyzing EEG data and location data in Senjogahara and investigating the relationship between them.
An Investigation Into Interpersonal Space and Conversation Distances of Chinese People for Different Artwork Styles and Genders
Authors: Li Yiyue
Published: June 2022

In modern life, people's demand for quality of life is also increasing, and the five senses experience is becoming the goal pursued by urban life, among which visual perception is the most direct and primary experience for human beings to receive external information, and is the most basic way of emotional experience. The so-called "judging people by their appearance" is a visually oriented "love at first sight", which actually affects people's psychology. The prevalence of artwork in overly busy offices suggests the hypothesis that, in addition to making interior spaces more aesthetically pleasing, the content of artwork may also affect our interpersonal distance as people's eyes scan over it. This study explored the interpersonal space (IPS) and conversation distances of Chinese people influenced by the presence of artwork in their interiors, and assessed the effects of both gender and artwork style (positive, neutral, and negative) on interpersonal space (IPS) and conversation distances. Fifty-one participants were recruited for this study. Participants were required to follow the same approach procedures in a face-to-face interpersonal space (IPS) and conversation distance task. The results showed that both gender and artwork style type had significant effects on interpersonal space (IPS) and conversational distance (p<0.05), where both greater interpersonal space (IPS) and conversational distance were preferred when the participant was female, and the effect of artwork style type was slightly more significant than gender（d1>d2), where both greater interpersonal space (IPS) and conversational distance were preferred when the artwork style was cluttered lines, gray colors, and negative emotions, and The opposite was true when the artwork style was fine lines, bright colors, and positive emotions, while the interpersonal space (IPS) and conversation distance values were in the middle of the distance generated by the positive and negative factors when the artwork style was not emotionally biased. This study may help to understand the benefits of people using positive or negative art decorations in a busy office environment with applications to interior design and social interaction.
Education in context and the variation of moods throughout Covid-19: An emotional design perspective, using the BRUMS methodology
Authors: Margolis Iara , Sampaio João , Providência Bernardo
Published: June 2022

The year 2020 was marked by the Covid-19 pandemic, where in addition to the whole situation of the danger of the virus, it had several emotional and social impacts. As a result of this scenario, in some places – such as Brazil – higher education classes have migrated to remote spaces. It is worth to notice that the educational sector is an important sector for the market and for society, and one of its metrics for strategic decisions is the understanding of student satisfaction. In turn, emotional design aims to understand the human being from an affective perspective, beyond functional issues. In view of this, this study aims to analyze the fluctuations of students' moods in the educational context, throughout the 2020 pandemic year, in the face of various milestones of the academic cycle, through the self-report tool BRUMS (Brunel Mood Scale) from the perspective of the emotional design. In total, there were 6 data collection moments, in two educational cycles, between April and December 2020, accounting for a total of 144 responses. As a result, it was possible to perceive the fluctuation of students' moods throughout the educational cycle in the pandemic period, evidencing the tension in the test periods, the fatigue during the lockdown, the vigor in the beginning and end of the semester. Anger was the least activated mood throughout the cycle, followed by depression. It was possible to perceive that BRUMS is a tool that helps in understanding mood, throughout the service cycle, enabling decision-making and planning of more user-centered services, in addition to a greater concern in emotional aspects to, in this case, promote a better academic experience in the educational context.
Design of a family product and service system "DOSE" to fulfill the emotional needs of patients with depression
Authors: Wang Xinqiao
Published: June 2022

The latest data from the World Health Organization (WHO) in 2019 [1] demonstrate that more than 350 million people suffer from depression worldwide, and depression is estimated to be the world's largest burden of disease in 2030. The major treatment methods for depression are drug therapy and physical therapy, both of which have limitations reflected in the lack of emotional communication between patients and their families [2]. This paper aims to solve the problem of emotional communication reconstruction between patients with depression and their families. Specifically, an auxiliary treatment service system based on the patient-family model of "DOSE" is developed to enhance the emotional communication between the patient and the family and assist depression patients in completing the treatment. Furthermore, the feasibility of the "DOSE" system is tested and evaluated with the empathy theory [3] and five sense design theory [4].
Rationale and Application of Express Algorithms for Mental Health Assessment in Professional Selection and Screening Examinations
Authors: Lytaev Sergey
Published: June 2022

The aim of this study was the physiological substantiation of express algo-rithms for assessing cognitive functions according to the data of clinical, psy-chological and neurophysiological studies in conditions of time deficit. The in-tegrative indicator SCL-90-R - "general index of severity" has a high statistical significance (p <0.05) in both healthy subjects and neuropsychiatric patients. The effectiveness of the "Mini-Mult" method in conditions of time deficit is de-termined by the results of the scales of hypochondria, depression, hysteria, par-anoia, psychasthenia, schizoid and hypomania (p <0.05). We also used a block of logical techniques. A similar survey for 15 - 25 min can be used as a stand-ard for assessing neurocognitive status in screening studies of large groups. EEG power indices and spectra in theta, delta and alpha frequency ranges are an effective reflection of mental status.

Published: June 2022

The technological properties of a system delivering simulation experience are a cru- cial dimension of immersion. To create a sense of presence and reproduce drivers behaviour as realistically as possible, we need reliable driving simulators that allow drivers to become highly immersed. This study investigates the impact of a system immersion of a driving simulator on the drivers’ brain activity while operating a con- ditionally automated vehicle. Nineteen participants drove approximately 40 minutes while their brain activity was recorded using electroencephalography (EEG). We found a significant effect of the system immersion in the occipital and parietal areas, prima- rily in the high-Beta bandwidth. No effect was found in the Theta, Alpha, and low-Beta bandwidths. These findings suggest that the system immersion might influence the drivers’ physiological arousal, consequently influencing their cognitive and emotional processes.

Published: June 2022

Latent Dirichlet Allocation (LDA) and Sentiment Analysis have become prominent tools in natural language processing applications for both research and industry. While LDA is a generative probabilistic modeling methodology that is widely used in Topic Modeling to extract underlying themes and topics from a collection of words, Sentiment Analysis is defined as identifying the hedonic tone of a corpus of text. Here, supervised Sentiment Analysis is used to classify conversations between team gaming dyads in terms of valence. Additionally, LDA is utilized to label segments of cooperative conversation between dyads as topics. Fourteen participants were paired as dyads (7 teams) and instructed to complete thirty-two 150 second gaming scenarios (trials) in the first-person shooter (FPS) video game Overwatch. While completing the scenarios, participants were instructed to communicate with their respective teammate via a voice communication headset. The conversations from each scenario were transcribed from recorded voice channels before analysis was performed. Our approach examines the relationship between perceived task difficulty and both conversation sentiment scores and topic frequency in both novice experienced skill groups. Preliminary results indicate evidence that conversation topic, sentiment and perception dynamics are consistent with an encouragement and frustration sentiment paradigm.

Published: June 2022

Video games provide a high-octane competitive sports platform where players with diverse skills engage in tasks that require precise control of cognitive skills and emotional responses. Electrodermal activity (EDA) is a portable, non-invasive, and wearable physiological activity sensing modality that captures correlates of emotional responses. In this exploratory study, we analyzed the EDA skin conductance data that we collected from healthy adult participants over their left index and middle fingers, while they were playing a first-person shooter video game. Participants played solo against easy and hard AI opponents, where the objective was to either escort a truck to its destination or prevent the truck from being escorted to win the game. The in-game behavioral performance results showed that, as expected, novice players struggled with the game more than experienced players: novices had fewer kills, died more, and finished the scenarios slower. Furthermore, EDA skin conductance results showed that experienced players showed significantly higher electrodermal activity than novice players while playing the game, both in the context of the phasic and tonic activity.

Much work has been done to engineer robots’ mechanical capabilities to best suit the general demands of their users and tasks. However, minimal research has addressed the impact of individual differences on perceptions of robot trustworthiness. These conclusions can provide guidance to optimize adaptive robotic systems in education, healthcare, and industry settings. This study examined the relationship between personality and human robot interaction in two contexts: (1) error-free and (2) errors. Assessment of individual differences were achieved via the Interpersonal Reactivity Index (IRI) (Davis, 1980) and robot trust assessed using the Multidimensional Measure of Trust (MDMT) (Ullman & Malle, 2018). This project provided a novel contribution in the field of human-robot interaction, highlighting the influence of technological failure on trust impressions of a social robot. Additionally, we sought to understand the degree to which empathy levels mediate these changes in trust.
Relationship between activation of prefrontal cortex and testosterone in N-back task
Authors: Makiko Aoki , Suzuki Satoshi , Anzai Ryouma
Published: June 2022

Purpose: Individual and gender differences are an important topic in the study of human cognition. In general, it has been shown that women are superior at verbal ability and associative memory, while men are better at tasks related to numbers, logic, and spatial recognition. Among them, it has been reported that cerebral blood flow in the prefrontal cortex increases during the N-back task, a working memory task. The relationship between sex hormones and cerebral blood flow remains unelucidated, although sex hormones and depressive mood are both factors that affect the function of the prefrontal cortex (cognitive function). Therefore, the present study aimed to clarify the relationship between the testosterone and cognitive function.Methods: The subjects included 6men and 16 women aged 20–35 years. Near infrared spectroscopy (NIRS), a brain function imaging device, was attached to the forehead of the subjects, and Oxyhemoglobin (Oxy-Hb) was measured during the N-back task. Oxy-Hb was measured during the N-back task using a NIRS system in the CHs 1-4 (right side), CHs 7-10 (center), and CHs 13-16 (left side) , and saliva was collected to measure the testosterone concentration. Subsequently, the correlation coefficient between the initial activation and testosterone concentration was calculated. This study was approved by the Institutional Review Board of the Kanagawa institute of technology (No. 20191011-01).Result: The items that were significantly correlated with testosterone were the initial activation CH13-16 in the 0-back task (r=48, p=.02). And the correct response rate (r=.42, p=.03), reaction time (p=.46, p=.03) and initial activation of CH13-16 (r=.68, p=.007) in the 1-back task. Conclusion: In adults, testosterone was associated with initial activation of the NIRS Oxy-Hb signal in the 0-back and 1-back tasks. Furthermore, in the 1-back task, testosterone was associated with correct response rate, the reaction time, and initial activation of the NIRS Oxy-Hb signal of CH13-16. This result suggests that testosterone may be related to left prefrontal cortex activation and responsiveness to presentation of the N-back task.

Beauty has always been the goal of human activity. The meaning of beauty is defined during its creation. The discussion of beauty by mathematicians has created the computational aesthetics. This paper reviews the related works in computational aesthetics of visual arts and summarizes the features used in aesthetic measurement. The features extracted from the visual artworks are divided into five types including visual, compositional, statistical, perceptual and artistic features. Based on those features, the visual images are quantified and analyzed on their aesthetic and artistic properties. The previous studies are mostly focused on the aesthetics of art production, the continuous process for artistic creation cannot be represented. Moreover, new forms of visual arts such as generative art emerged, which provide new opportunities and challenges to the field of computational aesthetics. A prospective on the algorithms for the evaluation of this new forms of visual arts will be given.

The aim of the article is to discuss the risks resulting from expanding access to the network of new devices, and at the same time to show to what extent the implementation of procedures in the field of data security and architecture of systems used for data processing may affect the security of the continuity of the company's technological processes, but also data protection. The author draws attention to the fact that the problem of data and process security in the Internet of Things should be considered not only in terms of the protection of the content of information, but also its authenticity and topicality. On the other hand, inadequate formulation of the rules of the Internet of Things security policy in a given enterprise may mean limiting the availability of solutions and access to data, often eliminating the possibility of obtaining and processing them altogether. Enterprises must therefore act in such a way as to help maintain both the functionality and security of their systems.

Management of construction site financial engagement is one of prerequisite of an effective site management. In recent times Building informatics concept has been useful in developing state of art equipment and process. In this study therefore, building informatics planning was generated that could be used for financial management purpose on site. The research was carried out using qualitative and quantitative research method, quantitative research method involved the use of structured questionnaire developed in Likert scale 1 to 5. Therefore with the aid of purposive sampling method, fifty (50) samples were picked using purposive sampling method. Construction professional constitute the nucleus of the respondents. The statistical inference was carried out on the data with Relative agreement Index and presented in tables. Qualitative method was used to develop the proposed integrated system. The study developed an integrated system that could assist in overcoming the negative vices of payment on site. The following task was carried out in line with aim of the study: identification of existing web-based financial platform, critical success factor in deployment of payment interface, methods of preventing financial conflict on site, challenges of web- interface, critical success factor in deployment of payment interface, identification of strengths and weaknesses of existing web-based financial platforms, among others. The interface can help solve basic problem about financial payment difficulty on site. The direction of choice should be in automating different aspect of building and construction for maximum productivity. The system that was developed in the context of this study can help prevent cost overrun on site, payment conflict, and delay payment among others.

People living in long-term care facilities due to physical or mental impairments have few opportunities for self-determined activity. Virtual reality (VR) technologies offer a potential to expand individual experience through immersive presence in artificial environments, to activate mentally and to promote autonomy through the impact of self-efficacy. The overall goal of the Austrian project VR4Care was to research design basics for the development of a motivating, gender-sensitive, personalized and cost-effective VR technology to increase the activation and quality of life primarily of residents in inpatient long-term care. In the further development of VR for senior citizens, gender-specific differences were taken into account, such as gender-specific requirements for user interfaces, gender-specific preferences in interests with regard to content and different expectations of support when using the VR-based system.

Affective states play a prominent role in the context of human activation and motivation. Immersive VR-based presence provides opportunities to activate elderly people in the context of preferred leisure activities (Häussl et al., 2021) or to apply mindfulness interventions for their cognitive reserve (Paletta et al., 2021). The appropriate design of positively activating content is pivotal for appropriate changes in users’ affective states. The presented study provided insight into the potential of non-invasive VR-based eye tracking for automated estimation of affective state induced by video content, in an explorative pilot study with seven elderly persons living in a nursing home. The results indicate the feasibility of estimating mood change from typical eye movement features, such as, fixation duration and pupil diameter, as a promising future research topic.

Nowadays, wireless technologies are increasingly being used for human needs. Increasingly, technologies are emerging that are used by people not only for the need to transfer data. One of these technologies is the Internet of Things, which often uses wireless sensors with ZigBee data transmission technology as end devices.There are areas that require deployment of these networks on the territory, a large number of sensors are required, which must with sufficient accuracy “know” their position on the deployment area. Usually, devices with built-in GPS modules are used for this, but devices containing this module are significantly more expensive than without it. And if in a large distributed network with many segments, more than 1000 such devices are required, then a device with a GPS module can only be at most one for each segment. Therefore, if this is a forest where there are many thousands of trees and it is necessary to monitor fires at the initial stage, which take place in many US states in the summer, then the cognitive task of teaching those devices, that do not contain a GPS module, to determine their position is relevant. This paper proposes a mathematical formulation of the cognitive task of learning to determine the coordinates of devices in wireless sensor networks. The study of the mathematical model has been carried out. The purpose of these studies was to find new alternative teaching methods for determining the distance between objects of IoT sensor networks, using the function of localizing objects where an emergency occurred.
Cross-cultural differences in thought and risk behavior – Implications for safety management
Authors: Murata Atsuo , Doi Toshihisa
Published: June 2022

It has been pointed out that thoughts are affected by culture. While eastern people have a more holistic way of thinking, western people have a more focused analytic way of thinking. Western people tend to behave based on internal attributes. On the other hand, eastern people tend to behave based on the interaction between internal attributes and situational factors. In summary, Western people cannot see the forests for the trees, which generally means that they cannot review the overall situation before discussing the details, and that they seem to infer causes based on effects. To the contrary, eastern people cannot see the trees for the forests and tend to have comprehensive belief and thus judge that they cannot know trees without seeing forests.The cross-cultural difference in thought is expected to lead to the cross-cultural difference in risk behavior. We have clarified cross-cultural differences in baseball game and working hours. Cross-cultural differences are also identified in a variety of fields such as corporate, finance, investment, policy making, management, or traffic behavior. It has been pointed out that individualism has a positive association with corporate risk-taking, whereas uncertainty (risk) avoidance and harmony have negative associations with corporate risk-taking. It has also been demonstrated that apparent differences in risk preference in buying prices for risky financial options were associated primarily with cultural differences in the perception of risk of the financial options. The cross-cultural differences in simulated driver risk-taking behavior have also been clarified. The frequency of risk-taking behavior differed among countries. Risk-taking was found to be higher for domestic firms in countries with low propensity of risk aversion and high individualism (cannot behave more holistically).In this manner, it is expected that cross-cultural difference matters in thoughts and risk behavior of corporate, finance, investment, and management, etc. This paper reviewed cross-cultural differences in thoughts and risk behavior and gave some implications for irrational decision making that took account of cross-cultural differences especially in safety management.
