Security systems must be continuously developed in order to cope with new challenges. One example of such challenges is the proliferation of sexual harassment against women in public places, such as public toilets and public transportation. Although separately designated toilets or waiting and seating areas in public transports are provided, enforcing these restrictions need constant manual surveillance. In this paper we propose an automatic gender classification system based on an individual’s facial characteristics. We evaluate the performance of QLRBP and MLLPQ as feature extractors combined with SVM or kNN as classifiers. Our experiments show that MLLPQ gives superior performance compared to QLRBP for either classifier. Furthermore, MLLPQ is less computationally demanding compared to QLRBP. The best result we achieved in our experiments was the combination of MLLPQ and kNN classifier, yielding an accuracy rate of 92.11%.

The City

Ecological and digital transitions alongside concerns over social inequalities have signalled the advent of complex new challenges for contemporary cities. These challenges raise issues pertaining to the dynamic capability of urban planners: more specifically, their ability to revise their tools and planning routines in urban projects. New paradigms of collective action for the transition towards innovative cities have been developed in large organisations. European companies, especially in public transportation, have developed such tools based on innovative design theories. One of these methodological tools, the Definition-Knowledge-Concept-Proposition (DKCP) process, was used to generate a new range of planning options for an urban district in Montreal, Canada. For many municipal organisations, the formulation of innovative ideas only concerns one stage of the process, represented by the ‘P’ phase. However, innovative routines should rather include the earlier phases of identifying the scope of possible innovations, the search for intriguing knowledge and disruptive design activities. The desire to tackle the complex challenges of 21st century cities has led to a new professional identity: the ‘innovative urban planner’.

This paper presents a novel gender classification method based on geometry features of palm image which is simple, fast, and easy to handle. This gender classification method based on geometry features comprises two main attributes. The first one is feature extraction by image processing. The other one is classification system with polynomial smooth support vector machine (PSSVM). A total of 180 palm images were collected from 30 persons to verify the validity of the proposed gender classification approach and the results are satisfactory with classification rate over 85%. Experimental results demonstrate that our proposed approach is feasible and effective in gender recognition.

Abstract Importance The COVID-19 pandemic has resulted in more than 3.5 million cases and 245 thousand deaths worldwide as of May 6, 2020. Determining the extent of the presence of the virus on public surfaces is critical for understanding the potential risk of infection in these areas. Objective To evaluate the presence of SARS-CoV-2 RNA on public surfaces in a densely populated urban area in Brazil. Design and Setting A total of 101 samples were collected from different surfaces in public places in the region of Belo Horizonte with the highest number of COVID-19 cases. Samples were collected near the hospital and public transportation areas using sterile swabs, and then submitted to nucleic acid extraction and genomic detection and quantification by one-step qPCR. Results Seventeen of the 101 samples tested positive (16.8%) for SARS-CoV-2 RNA, including samples from bus stations/terminals, public squares, and sidewalks, including those near hospitals. Conclusions and Relevance Our data indicated the contamination of public surfaces by SARS-CoV-2, especially near hospital areas, highlighting the risk of infection for the population. Constant monitoring of the virus in urban areas is required as a strategy to fight the pandemic and prevent further infections. Key points Question Can SARS-CoV-2 be detected on surfaces in public areas used by a large proportion of the population? Findings SARS-CoV-2 RNA was detected in different locations, including bus stations/terminals, squares, and sidewalks, especially those near hospitals, in a densely populated area of Belo Horizonte, Brazil. Meaning This study highlights the need for constant monitoring for the presence of SARS-CoV-2 RNA in urban areas to support better strategies to fight the COVID-19 pandemic and prevent further infections.

Introduction: Childbirth can be a normal and nonintervention process, but sometimes the process gets out of normal and requires immediate medical intervention. Thus, home delivery cannot be considered safe without coordination with the treatment staff. Sometimes fear of Covid-19 epidemic prevents mothers to go to the hospital for childbirth and they decide to do it in an unsafe condition, which puts the health of the mother and the neonate at risk. Presentation Case: Our case was a pregnant woman  with a negative blood group (A-)  who did not come to the hospital because of fear of contracting Covid-19 from the hospital and decided to give birth at home without medical and midwifery support. After giving birth at home, she called the midwife who was taking care of her pregnancy. But she was still afraid to go to the medical center for postpartum care. The midwife informed the mother and her husband that they would be transferred to the midwifery clinic for further care and follow-up, with the necessary counseling and assurance of protective care to control Covid 19 transmission. Conclusion: Counseling and training of protective methods during pregnancy can reduce the concerns of pregnant women. It is also recommended that pregnant women avoid unnecessary travel, public places, use of public transportation and contact with sick people, and most importantly, observe personal and public health issues. Some pregnant women may experience severe anxiety and depression during epidemics such as Covid 19, which require educational psychological counseling and continuous psychological support to prevent unintended consequences.

Gender Based

Background: Gender recognition is one of the most challenging perceptible tasks that receiving attention in the increasing digital data era as the requirement of personalized, reliable and ethical system inevitable. A problem that we address in this paper, greatly deals with the gender based identification system. We are motivated by this problem as many recent social interactions and existing services rely on the gender of an individual, and also in forensic identification, the gender information provides the feasibility for easy and quick investigation. Objective: The paper primarily focused on the gender based identification problem and culminate a robust gender based recognition system with the higher accuracy rate. We attempted to perceive the gender of an individual through the multimodal biometric system by integrating the three prominent biometric traits namely: fingerprint, palm-print and hand in a specific manner. The proposed multimodal biometric for gender recognition system provides a better accuracy rate improvement with the optimal feature set which are generated from available high dimensional features set. Method: Aiming for the objective to reduce the search space, a hybrid meta-heuristic approach GSA-Firefly (GFF) is introduced in this paper. The optimization approach GFF is proposed to retrieve the optimal number of features from the high dimensional features generated by fusing the texture features of all the three considered biometric traits along with the fingerprint minutiae features. Further, the decision tree classifier is used to classify the gender of an individual. Results: The feasibility of the proposed approach is measured with different qualitative performance parameters. In light of achieving the accuracy rate of 99.2%, it shows that its performance comparatively better against other techniques reported in the literature with the different sets of classier. Conclusion: The hybridization technique that effectively integrate meta-heuristic approaches GSA and firefly outperforms other similar approaches with respect to obtaining the optimal features of multimodal biometric for gender based identification system. Further, the novel technique enhance the overall performance of the system by reducing the search space over time and space.

Background: Although the government of Bangladesh made the use of masks mandatory in public settings during COVID-19, individuals have been reluctant to follow. We intended to know how many people used face masks in public settings during COVID-19. Methodology: This study was conducted in several public settings in Shahbag, an urban sub-district of Dhaka; and Sirajdikhan, a rural sub-district of Munshiganj in Bangladesh on November 2020. A total of 4011 people were identified from the video-graphic data captured from 20 public places for monitoring the use of masks. Finding: More than two-thirds of those observed had no face masks or did not utilize them properly. People in urban regions (43%) used mask more in an appropriate manner than those in rural areas (26%). Females wore masks comparatively more than males (53% vs. 35%, p-value <0.001). People used masks more in the morning than in the afternoon (39% vs. 34%, p-value <0.001). People were seen to use a mask more in hospital areas (60%) than in other places. However, in public transportation stands only one-fourth (25%) of the people wore a mask in an appropriate manner. In binary logistic regression male sex, rural area, public places and time of observation (afternoon) were found as risk factors for not wearing a mask. Interpretation: The general population of both rural and urban areas of Bangladesh is reluctant to wear face masks. Along with the ongoing vaccination campaign, people of Bangladesh need to wear masks for the prevention of COVID-19. Funding: This research has been partially supported by Bangabandhu Sheikh Mujib Medical University.

<em>Sexual harassment is still considered irrelevant to voice, let alone to fight for. People tend to put more concerns on family honor, and even consider sexual harassment as a shameful act and degrading their family’s name. Apart from at home, sexual harassment also often occurs in public places—public transportation, workplaces, schools, and other public facilities. Saling Jaga is a forum that voices concerns on sexual harassment that occurs in public spaces, and is the result of a collaboration amongst 3 undergraduate programs, (1) Law, (2) Communication Studies, and (3) Visual Communication Design, at President University. Saling Jaga forms a team that is hailed as Guardians. The purpose of this movement is to raise the awareness of everyone who witnesses sexual harassment in public places and has the courage to look after each other (bystander intervention) through activities in the form of socialization on Instagram social media, exhibition installations, and seminars to secondary schools in Kuningan.</em>
