Abstract. The COVID-19 pandemic prompted schools to close in 2020, and with its negative impact on the quality of learning, the conversation shifts to the re-opening scenarios. In this study, we coupled a COVID-19 agent-based model (ABM) with social contact probabilities from pre-pandemic estimates. We then simulated school re-opening and vaccination scenarios in Quezon City, Philippines using our ABM. Our toy simulations suggest that the city could already re-open schools with 50% vaccination coverage. However, we suggest that students shall be vaccinated first, mask-wearing and physical distance shall be strictly observed, and schools shall only be re-opened by 25% as a precaution. Policymakers may take insights from the study.

As a result of increase in the number of residents of megacities, the anthropogenic impact on the public, recreational and agricultural areas is increasing. Anthropogenic load causes degradation of the natural structure of the city and has a negative impact on public health. In current situation, more recreational areas are organized for residents of the city. However, the organization of recreational areas does not always comply with the population requirements. In the formation that sort of spaces, it is necessary to obtain complete and reliable information about the quality of the environment, which can only be obtained through the regular monitoring studies. This article considers a number of recreational, agricultural and public areas under the noise exposure. The spatial organization of recreational areas should be carried out taking into account the main goal of creating a comfortable architectural and planning structure of the urban environment. This article shows the insolvency of the public, recreational and agricultural areas as comfortablespaces.

The article analyzes the impact of digitalization on the life population quality, identifies areas, identifies the positive and negative impact of digitalization on the qualitative characteristics of the population’s life. The life quality is one of the important indicators of the level of development of society; it is a complex systemic integral characteristic of satisfaction with material and non-material factors of life of the population living in a certain territory. Since the environment and environmental conditions are constantly changing, various trends and patterns occur, the trends and requirements of our time, inevitably affect the life quality. One of such conditions, gaining momentum at the present time, is digitalization. Digitalization is the introduction of modern digital technologies in various spheres of life and production. Currently, in all types and levels of economic processes in the world and in individual countries, the so-called “digitalization” is gaining momentum - the active use of information and communication technologies. There is a need to accept digitalization as a universal process, adapt to it and use its levers for the best possible result for society. In nine areas, digitalization directly affects the life quality - the city, education, healthcare, economy, finance, information systems, infrastructure, business, and agriculture.

ABSTRACTCities are spatial plans on the surface (land) with administrative boundaries that have been determined where there is concentration of the population in it along with various economic, social and political activities. The city is a residential spatial structure with a large number of people on limited urban land, which is generally non-agrarian. The development of the city does not always have a positive impact, but it has a negative impact including the emergence of slum areas around the city center. Around the city center there are various centers of activity including tourism, health, education and trade as well as services in the city, provincial and national levels. The five activities are developing quite rapidly which has resulted in the development of residential areas around the city center and the poor development of slums in these locationsThe purpose of this study is to analyze the factors that influence the development of slums. The research location is in the city of Bukittinggi, West Sumatra Province. This study uses primary data by distributing questionnaires to households throughout the City of Bukittinggi. The analysis used is logistic regression analysis. The results showed the factors that influence the development of slums including the Quality of Dwelling, Building Density, Education and Road Accessibility. These influencing factors can be used as a reference for alleviating slums in Bukittinggi City.Keywords: cities, households, slum areas. ABSTRAKKota merupakan suatu tempat pemusatan berbagai kegiatan manusia baik dari kegiatan sosial, kegiatan ekonomi, maupun kegiatan politik dimana berkonsentrasi pada satu tata ruang di atas permuakaan (darat) yang memiliki batas-batas wilayah administrasi yang sudah ditetapkan. Kota merupakan suatu tata ruang permukiman berpenduduk dengan jumlah yang banyak di atas lahan perkotaan yang terbatas, yang pada umumnya bersifat non agraris. Perkembangan kota tidak selalu menimbulkan dampak positif, namun memiliki dampak negatif diantaranya munculnya kawasan permukiman kumuh di sekitar pusat kota. Di sekitar pusat kota memiliki berbagai pusat  kegiatan diantaranya pariwisata, kesehatan, pendidikan dan perdagangan serta jasa baik di lingkup kota, provinsi maupun nasional. Kelima kegiatan tersebut berkembang dengan cukup pesat yang mengakibatkan berkembang kawasan permukiman di sekitar pusat kota dan buruknya berkembang permukiman kumuh di lokasi tersebut. Tujuan dari penelitian ini adalah untuk menganalisis faktor-faktor yang mempengaruhi perkembangan permukiman kumuh. Lokasi penelitian berada di Kota Bukittinggi Provinsi Sumatera Barat. Penelitian ini menggunakan data primer dengan menyebarkan kuesioner ke rumah tangga se-Kota Bukittinggi. Analisis yang digunakan adalah analisis regresi logistik. Hasil penelitian menunjukkan faktor-faktor yang mempengaruhi perkembangan permukiman kumuh diantaranya Kualitas Hunian, Kepadatan Bangunan, Pendidikan dan Aksesibilitas Jalan. Faktor-faktor yang mempengaruhi ini dapat dijadikan sebagai acuan guna pengentasan permukiman kumuh di Kota Bukittinggi.Kata kunci: kota, rumah tangga, permukiman kumuh.

AbstractBackgroundThe nonpharmaceutical interventions (NPIs) for contact suppression have been widely used worldwide, which impose harmful burdens on the population and the local economy. The evaluation of alternative NPIs is needed to confront the pandemic with less disruption. By harnessing human mobility data, we develop an agent-based model that can evaluate the efficacies of NPIs with individualized mobility simulations. Based on the model, we propose the data-driven targeted interventions to mitigate the COVID-19 pandemic in Hong Kong without city-wide NPIs.MethodsWe develop a data-driven agent-based model for 7.55 million Hong Kong residents to evaluate the efficacies of various NPIs in the first 80 days of the initial outbreak. The entire territory of Hong Kong is split into 4,905 500m×500m grids. The model can simulate detailed agent interactions based on the demographics data, public facilities and functional buildings, transportation systems, and travel patterns. The general daily human mobility patterns are adopted from Google’s Community Mobility Report. The scenario without any NPIs is set as the baseline. By simulating the epidemic progression and human movement at the individual level, we proposed model-driven targeted interventions, which focus on the surgical testing and quarantine of only a small portion of regions instead of enforcing NPIs in the whole city. The efficacious of common NPIs and the proposed targeted interventions are evaluated by extensive Monte Carlo simulations.FindingsWithout NPIs, we estimate that there are 128,711 total infections (IQR 23,511-70,310) by the end of the 80-day simulation. The proposed targeted intervention averts 95.85% and 94.13% of baseline infections with only 100 (2.04%) and 50 (1.02%) grids being quarantined, respectively. Mild social distancing without testing results in 16,503 total cases (87.18% infections averted), rapid implementation of full lockdown and testing measures (such as the control measure in Mainland China) performs the best, with only 805 infections (99.37% infections averted). Testing-and-quarantining 10%, 20%, 50% of all symptomatic cases with 24-hour/48-hour avert 89.92%/ 87.78%, 95.47%/ 92.42%, and 97.93%/ 95.61% infections, respectively.InterpretationBig data-driven mobility modeling can inform targeted interventions, which are able to effectively contain the COVID-19 outbreak with much lower disruption of the city. It represents a promising approach to sustainable NPIs to help us revive the economy of the city and the world.

Bandung is known as the capital of West Java. Bandung also develops as a culinary city. As a form of the Government's responsibility to facilitate tourists who come to Bandung, the Government has officially announced the "Bandros" Tourism Bus (Bandung Tour on Bus). But practically, there are many problems faced by stakeholders. Standardization of prices among passengers, limits on the number of buses that cannot serve passengers, unclear routes including departures and arrivals, unhealthy management for safety factors and an increase in the number of passengers that have a negative impact due to the quality of service. The purpose of this study is to describe service quality, community satisfaction and community interest in reusing Bandros, and also to obtain the results of an analysis of the extent to which service quality affects community satisfaction and its impact on community interest in reusing Bus Bandros. In this study, researchers used the descriptive-verification method. This method is used to verify the quality of service perception, community satisfaction and community intentions to reuse Bus Bandros by involving 500 respondents who wish to use Bus Bandros. The distribution and selection of respondents was carried out using convenience sampling. Path analysis is also used in this study. Based on the results of the statistical testing process found significant perceptions between service quality variables and brand image with public interest in the city of Bandung to use Bus Bandros. For recommendations in this study, clarity of information can increase the public's intention to use Bus Bandros, because the information submitted will provide clarity in order to increase public intention to ride Bus Bandros.

Background: More than 122,000 COVID-19 associated deaths have been reported in Colombia and about 27,000 in the city of Bogotá by the first week of August, with vaccination coverage in the city at 30% for complete schemes and at 37% for partial vaccination. As the incidence of cases currently decreases, questions remain about the potential impact of the delta variant already present in the city. Methods: We used an agent-based model calibrated to data on age-structured deaths and dominance of variants in Bogotá. We used efficacy data for the portfolio of vaccines available, including known changes for SARS-CoV-2 variants. We modelled scenarios of early and delayed introduction of the delta variant in the city along with changes in mobility and social contact, and vaccine strategies over the next months. Findings: We estimate that by mid July, vaccination may have already prevented 17,800 (95% CrI: 16,000 - 19,000) deaths in Bogotá. The delta variant could become dominant and lead to a fourth wave later in the year, but its timing will depend on the date of introduction, social mixing patterns, and vaccination strategy. In all scenarios, higher social mixing is associated with a fourth wave of considerable magnitude. If an early delta introduction occurred (dominance by mid July), a new wave may occur in August/September and in such case, age prioritization of vaccination and second dose not postponed are more important. However, if introduction occurred one or two months later (dominance by mid August/September) the age-prioritization is less relevant but maintaining the dose scheme without postponement is more important. In all scenarios we found that increasing the vaccination rate from the current average of 50,000/day to 100,000/day reduces the impact of a fourth wave due to the delta variant. Conclusions: In Bogotá, the delta variant could still lead to a fourth wave, whose magnitude would depend on its introduction time and the level of social mixing. Its impact can be mitigated by increasing vaccination rates to achieve high coverage quickly, with non-delayed second doses. We found that, at this point, suspending the age prioritization to achieve higher coverage with first doses does not seem to have a major effect on deaths and ICU demand. But, delaying the second dose may not be beneficial and may even increase the incidence of severe outcomes.

Capacity building is a process that occurs within the community itself.Outsiders cannot develop people, organizations, or communities, but it is the people,organizations or communities themselves who can develop themselves. Outsiders canonly support by facilitating the process to accelerate their development, and help findaccess to the resources and inputs needed .Currently, improving the quality of learning isthe dream of all teachers. The existence of an active role from all components willrealize learning that is truly quality and also of high quality. The quality of learning canbe realized and achieved when teachers are able to, among others, boost students'learning motivation. Motivation is a psychological condition that encourages someone todo something. Ibtidaiyah madrasas in the city of Surabaya, the majority of their learningquality is still far from expectations; and this is due to the low capacity of teachers.Thus,mentoring at MI Al Hidayah Margorejo Surabaya to develop teacher capacity inincreasing students' learning motivation is urgent and significant in order to equip themto be later applied in learning activities for the convenience of achieving competence forstudents. This assistance can contribute in the form of developing teacher capacity inincreasing student learning motivation at MI Al Hidayah Margorejo Surabaya.
