Learnings from User Digital Trail Post-Occupancy Evaluation before COVID-19 for Future Workplace Analysis and Design

Data are required for optimizing workplace design, assessing user experience, and ensuring wellbeing. This research focuses on the benefits of incorporating post-occupancy evaluation (POE) data analysis by studying the digital trail of employees generated by the existing Wi-Fi infrastructure of the office. The objective is to enable a safe return to offices through compliance with COVID-19 space-capacity regulations and in consideration of the health and wellbeing of employees. Workplaces, teams, and people have become more digitalized and therefore more mobile due to the globalization of knowledge and cutting-edge technological innovations, a process that has been accelerated by the COVID-19 crisis. Now, hybrid work and fully remote working routines are increasing in a significant number of companies. Nevertheless, with the return to the office, understanding how to calibrate spatial capacity is now key for workplaces and companies. Traditional assessment methods are obsolete; new methods that respond to mobility, changing occupancy rates, and comfort are essential. This paper analyzes, through the case study of a pre-COVID-19 activity-based office, the advantages of using digital indoor-location techniques (such as Wi-Fi networks, which additionally have the advantage of being previously installed in the majority of these spaces). The paper demonstrates that the incorporation of digital POE of user trends enabled a more seamless, accurate, and scalable return to a new normal office work scenario and an improved post-COVID-19 design of workplaces.

Asymptotic Analysis for Systems with Deferred Abandonment

This short paper concerns the analysis of the M/M/k queueing system with customer abandonment. In this system, service managers provide a finite buffer space, which is a waiting area that prevents customers from abandoning the system. Abandonment of the system can occur from reneging (exiting from the queue while waiting), and/or balking (leaving the system without waiting). We derive an analytical expression to represent the impact of the buffer space capacity on the delay probability and the abandonment probability for a system with deferred abandonment. The result indicates the provision of the buffer space in a large system could only increase the delay probability while the abandonment probability remains unchanged. Despite the benevolent intentions of service managers, providing a buffer space may exacerbate the performance of larger systems.

PARKING PULL IN THE TAMAN PASUK KAMELUH TOURISM AREA (STREET S. PARMAN, PALANGKA RAYA CITY)

This type of research used in this research is descriptive research with a qualitative approach. The data needed to complete this research includes primary data obtained from field surveys which are used to obtain parking attraction and parking space capacity, while secondary data is obtained from the Perkim Service (Public Housing and Settlement Service) Palangka Raya City. The results of this study indicate that, Parking Space Capacity = 53 ÷ 0.75 = 70.6 motorbikes = 71 motorbikes, the highest parking accumulation is on Sunday at 15.00 WIB - 16.00 WIB for 62 motorbikes, the highest parking volume on Sunday is 258 vehicles/days/space, parking turnover rate (trun over) = 258 ÷ 145 = 1.7 vehicles/day/space, the average parking index per day is 10.71%, 11.41%, 6.1%, and park parking needs are 33 x 53 = 1,749 m2. Based on the results of the calculation of the parking attraction that occurs in the Taman Pasuk Kameluh area, Palangka Raya City, it is 258 vehicles/day/space. For travel attraction compared to the number of motorbike parking lots available to accommodate vehicles in the Kasuk Kameluh park area, it is 70.6 vehicles/day. So based on the results obtained, the demand for parking space exceeds the existing parking capacity, only 53 parking pedals (demand) exceed the existing parking capacity.

KAJIAN STRUKTUR SOSIAL MASYARAKAT NELAYAN DI EKOSISTEM PESISIR (Study of Social Structure of the Fisherman Community in Coastal Ecosystem)

Research aim is to analyse any social changes and dynamic of space capacity and critical point of social structure in coastal ecosystem. The main factor of structural change is external factor of structural formation (individu , system), or increase of community access to the change of local social environment, and external social environment. Dynamics of space capacity of social structure in coastal ecosystem of Bungus Teluk Kabung Padang during periode of research can be explained through the two indicators, objective and subjective. There are a general critical point and a special critical point. This results explain that a evolution theory suggest a high possibility to be synthesized with any other theories, e.g. a conflict theory, an equilibrium theory, and a “timbul-tenggelam” theory. The synthesis process is an operational stage in a schematic mapping of theories by Appelbaum. Dynamics of social structure must be known bt any goverment and NGO, which have any development plans in the fisherman community.

Queueing Systems with Random Volume Customers and their Performance Characteristics

In the paper, we consider non-classical queueing systems with non-homogeneous customers. The non-homogeneity we treat in the following sense: in systems under consideration, we characterize each customer by random capacity (volume) that can have an influence on his service time. We analyze a stochastic process having the sense of the total volume of all customers present in the system at given time instant. Such analysis for different queueing systems with unlimited or limited total volume can be used in designing of nodes of computer and communication networks while determining their buffer space capacity. We discuss basic problems of the theory of these systems and their performance characteristics. We also present some examples and results for systems with random volume customers

Milling Activation for the Solvent-Free Synthesis of Zeolites. A Practical Guide

The paramount challenge of current chemical technology, including catalysis, is meeting the ecological sustainability requirements. The feasible production of zeolites is crucial because they constitute the principal group of heterogeneous catalysts. However, current zeolite manufacturing via hydrothermal synthesis is connected with considerable consumption of water resources, generation of wastewater, and significant equipment costs. Solvent-free strategies have attracted great attention as high-yielding methods for sustainable synthesis, particularly beneficial in terms of water consumption minimization and an outstanding increase in production due to the efficient use of synthesis space capacity. So far, the solvent-free preparation of numerous zeolite materials has been performed with the preceding grinding of reagents in a mortar. The proposed article describes recent advances in the application of automatized milling instead of manual work. Pretreatment automatization makes the entire process well-controlled, less sensitive to human factors, and is significantly more relevant to industrial scale-up. Moreover, the automatized milling activation unlocks opportunities for solvent-free synthesis from a broader range of common reagents, where the manual treatment is not efficient. Possibilities and limitations of the milling methods are discussed on the basis of a comprehensive analysis of parameter optimization, activation mechanisms, and applicability of common reagents used for zeolite production.

АДАПТАЦІЯ FASHION-ІНДУСТРІЇ ДО ГЛОБАЛЬНИХ СВІТОВИХ ПРОЦЕСІВ

The moods and categories of consumers of fashion industry goods analysis in the context of global processes are the main purposes of this study. Methodology. An analytical method was used to study consumer trends in the fashion industry. The main categories of consumers of the fashion industry are determined by the method of synthesis. It is recommended to integrate the obtained categories by the induction method into the marketing activity of the fashion brands. Results. The most important moods of world consumers in the conditions of global world processes were investigated in the work. Four main sentiments have been identifi ed: fear, just resilience, a desynchronized society, and radical optimism. In order to establish the main ways of behavior of players in the market of the fashion industry, the categories of consumers of industrial goods were identifie d: stabilizers, settlers, new optimists. The key areas of new methods of interaction of fashion brands with consumers are the following: - ease of decision-making (sales in stores with a limited range will grow);- quiet trade (rejection of daily uncertainties);- unifi ed commerce (creates uninterrupted interaction with customers on all channels);- referral to archives (resale industry shows signs of acceleration);- hyperlocalized social commerce (possibility of earning a commission for all participants of the offline / online retail chain);- attracting attention to the cities of the second level (shifting attention from oversaturated cities of the 1st level to remote cities of the 2nd level, providing high-speed logistics);- AR / VR purchases (use of virtual reality);- evolution on demand (simplifi cation of US-design (user experience) in the online space - capacity (and savings) of packaging (group purchases at reduced prices, minimization of packaging).The obtained data are recommended for implementation in marketing and management activities of Ukrainian fashion brands.
