Abstract
Maintaining the hotel’s operational stage and its tangible value is significant for hotel industry as the industry relies on customer satisfaction towards the service. Since the hotel industry services are vary and complex, it is crucial to recognize the contextual characteristics and understand the surrounding environment of operations through its performance effectiveness during its operational. However, issues on the maintenance management of aesthetic performance, service hospitality and awareness on sustainable interiors products are significant concerns in the hotel’s performance in operational stage. Hence, this paper aims to develop a conceptual framework consisting of the sustainable interior design (SID) criteria and components that relates to hotel’s operational performance effectiveness. A semi-structured interview was carried out in this study involving 18 experts comprises of interior designers’, architects, and maintenance managers of green certified hotels. The data is analysed using ATLAS.ti9© qualitative software. The findings revealed that there are eight (8) sustainable interior design (SID) components consists of biophilic, energy efficiency, water consumption, health and social flexibility, environmental comfort, ergonomics, green awareness as well as sustainable site planning and management. It was found that there are 37 SID components sub-divided from the criteria which relates to the hotel’s performance effectiveness. This study is significant for the hoteliers in identifying critical elements contributed to the successful performance by integrating facilities management to the SID.

Abstract
Forming a bond with nature is very important in children’s lives to improve their well-being as a child and later as adults. However, nowadays, children are disconnected from the natural and outdoor environments. Children’s leisure activities have changed from being actively involved in outdoor activities to passively being confined to indoor activities aided by gadgets. Children face various problems as the consequences of being disconnected from nature. Hence, it is important to reconnect children with nature by including nature through biophilic design in their spaces. However, limited is known on the trends of biophilic design application at children’s spaces. Also, limited is known on the benefits of biophilic patterns in children’s spaces on children. Based on a systematic review, this paper presents a review on the trends of biophilic design application in children’s spaces that include the biophilic pattern used, the benefits of biophilic elements on children, study context, respondents and participants. The review also highlights the methodology used with children in the studies. The result shows evidence that children’s spaces, such as schools, should implement biophilic elements to strengthen the relationship between children and nature and improve their well-being. Gaps from previous research were discussed. Also, directions for future study were outlined.

Abstract
This paper is devoted to the issue of post-war reconstruction of damaged buildings and, in particular, panel construction as the most massive in Ukraine. The main structural features of large panel system (LPS) buildings are given and the existing experience of their renovation. Taking into account the state of the industrial base in Ukraine and the impossibility of quick rebuilding of panel houses from the elements of this construction system (precast panels), a new precast-monolithic frame is proposed, which is based on the production of structural elements in a permanent formwork printed using a 3DCP. Basic solutions for columns, beams and slabs have been developed. As an implementation, numerical simulation of a damaged 16-storey panel building with the proposed superstructure system is performed. The obtained results confirmed compliance with all the requirements of regulatory documents for the ULS and SLS limit states and al-lowed the reconstruction of the building to be implemented.

Abstract
Nowadays, the war in Ukraine brings not only material and human losses, but also significant environmental damage. The full-scale Russian invasion of Ukraine led to serious environmental consequences for the country’s northern, southern and eastern regions. Water treatment from surface sources occurs according to various technological schemes. Still, the most common scheme for water treatment plant with productivity of 30,000 m3/day or more is a two-stage scheme with a horizontal settling tank in the first stage and rapid sand filters in the second stage. Disadvantages of horizontal settling tank are uneven water distribution across the sump, longitudinal circulation, an insufficiently efficient drainage system for clarified water, and unsatisfactory operation at low temperatures. To intensify the operation of horizontal settling tanks, we proposed next solution: to place thin-layer continuous settlers with countercurrent water movement at the beginning of the sedimentation zone. Such an arrangement makes it possible to retain suspended particles at the facility’s beginning, reduce the mud load on the horizontal settler and increase the water velocity in thin-layer settlers. This research aims to intensify the operation of horizontal settling tanks and improve the quality of water clarification. Experimental studies of the combined horizontal settling tank design were conducted. It shows the efficiency of its work, improving the quality of water treatment.

Abstract
A fundamentally new technology of intensive saturation of the porous space of concrete or reinforced concrete has been developed, which makes it possible to significantly increase the degree of filling the pores and, therefore, to extent increase the strength and density of the material being saturated with a hardening liquid. The results of the experiments show that the strength of concrete has increased, and the water absorption rate has significantly decreased. This is achieved by creating an internal vacuum in the cement matrix. The structure of the porous space of concrete after impregnation became significantly denser: capillaries, pores, microcracks and various defects were filled with sodium silicate and created a structure that practically does not allow moisture to penetrate into the concrete body, the water absorption value decreased to 1.15%.

Abstract
Calculations of the characteristics concerning the heat exchange equipment of the Flash/ORC power plant for the usage in waste heat recovery (WHR) cogeneration plants are presented. The use of hybrid power plants with water steam and organic working fluids, on the one hand, leads to an increase in the mass of the heat exchange equipment, and on the other hand, it ensures the generation of electrical energy and heat at high temperatures of the heat source, when the use of high-temperature working fluids is limited their thermal stability (for example, the thermal stability of silaxanes is about 300 ºC). Calculations are performed for a heat source with temperatures of 250ºC and 350 ºC. The generated electrical power of the power plant at a heat source temperature of 350ºC is 460 kW. The generated thermal power by capacitors is 1755.3 kW. The mass of the capacitors of the second and third circuits is 5000 kg and 14500 kg, respectively. It is shown that when the temperature of the heat source decreases to 250ºC with a double-circuit design, the mass of the heat exchange equipment decreases. Thus, the mass of the condenser is 12700 kg, and the generated thermal power is 1430.2 kW. The values of the heat exchange surface area of a direct-flow steam generator with flue gases, and an intermediate steam generator between the stages of the thermal circuit of a regenerative heat exchanger, as well as a water-cooled condenser are given. When the condenser is cooled by atmospheric air, the surface area of the condenser increases significantly. A characteristic feature of organic working fluids is the low efficiency of heat exchange in heat exchangers, especially at low temperatures. The heat transfer coefficient in heat exchangers with organic working fluids is about 1500-2800 W/(m2•K), which causes an increase in the heat exchange surface area. In this case, it is necessary to reduce the diameters of pipes in the heat exchangers of the steam generator, to use the pipes with internal ribs, and coil pipes in order to reduce the pipe length. The use of steam generators with coil steam-generating channels, characterized by a higher heat exchange intensity, is promising. The selection of the optimal structure and parameters of the ORC installation is carried out taking into account the mutual influence of steam turbine units on the efficiency of working processes in general.

Published: August 2024

Abstract
Current economic relations show that the market for road construction materials needs competitive products of relatively low cost. Such products can be obtained, inter alia, using local natural raw materials, industrial waste and processing. The article is devoted to the current topic of using industrial waste in the field of road construction for the purpose of recycling and rational use of traditional road building materials. In recent years, against the backdrop of a significant increase in road construction, options for using phosphogypsum for the construction of roads of all categories are being actively proposed. Currently, about 50 million tons of phosphogypsum have been accumulated in the dumps of industrial enterprises, and these numbers are increasing every year. Phosphogypsum is calcium sulfate dihydrate and can be used as a binder for strengthening soils, constructing foundations, during repair work, in asphalt concrete and cement concrete mixtures. The use of phosphogypsum is possible both in its pure form and modified to improve the performance properties of the final product. The article presents the positive results of experiments on the use of phosphogypsum modified with sulfur in crushed stone-sand mixtures for the construction of foundations, asphalt concrete and cement concrete mixtures. The purpose of this study is to analyze ways to reduce the cost of construction, reconstruction and major repairs of low-category roads by using production and consumption waste in the structural layers of road pavements.

Published: August 2024

Abstract
The paper aims to investigate the significance of energy efficiency during Ukraine’s post-war recovery and strategies to improve energy efficiency in buildings in mass housing estates. The motivation for improving energy efficiency is to strengthen the country’s energy independence, reduce the burden on the national budget, meet political commitments, and reduce negative environmental impacts. Currently, energy efficiency in Ukraine lags behind that of European Union countries, necessitating a review of policies and strategies in this field. The inefficient energy use by outdated housing structures has a negative impact on overall energy efficiency. To improve energy efficiency in the housing stock, it is crucial to target Soviet-era mass housing estates, which represent a considerable proportion of the country’s housing supply and fail to meet modern standards. This article provides an overview of the energy-efficient renovation strategies applied in Germany. These endeavors involve reducing heat losses caused by convection and conduction, regulating solar gains, and improving the energy efficiency of technical systems that cater to building services and occupant comfort.

Published: August 2024

Abstract
A conceptual scheme of a monitoring mechanism for early diagnosis of crisis socio-economic situations in regions and the choice of preventive measures aimed at reducing the level of socio-economic tension (SET) in regional systems operating under the influence of “shocks” is proposed. Implementation of the modules of the proposed mechanism for these regions of Ukraine was carried out, analysis and predictive modelling of the level of socio-economic tension in the regional systems of Ukraine was carried out using such machine learning methods as cluster analysis, taxonomy, reduction methods, classification methods with training, regression analysis on panel data, vector autoregressive models and error correction models. The results obtained made it possible to single out regions with different types of development. An analysis of the regions by the level of economic tension showed that 79% of the regions of Ukraine belong to regions with a high level of economic tension. The share of regions (58%), which are characterized by crisis development, remains high. Inertial and alternative scenarios for the socio-economic development of the region have been formed, and the best scenarios have been identified to reduce the level of SET. The proposed management mechanisms are universal and can be used for adapting regional strategies.
Analysis of variable fluidic properties with varying magnetic influence on an unsteady radiated nanofluid flow on the stagnant point region of a spinning sphere: a numerical exploration
Authors: Bag Raju , Kundu Prabir Kumar 
Published: August 2024

Abstract
The purpose of this article is to invent the impact of inconstant properties of fluids on the nanofluidic stream towards the stagnation area of a revolving sphere. The motion is treated as an unsteady radiated flow with a nonlinear sort of heat radiation. It is presumed to have Brownian motion & thermophoretic impact in our flow model. Additionally, a variable magnetic influence is addressed perpendicularly on the spherical surface. A suitable alteration has been applied to make dimensionless of our prime flow profiles. The translated equations and the limiting restrictions are solved through a numerical approach. The well established method RK4 Shooting technique is utilized here with Maple 2017 software. In the exploration of the consequences of requisite parameters on thermal, concentration, and flow features, numerous schematics are involved. The nature of physical quantities like Nusselt numbers, friction coefficients, and Sherwood numbers is stated in a tabular manner. It is perceived from the outcomes that the fluid velocity towards the x-direction is reduced for the variable viscosity parameter, whereas the unsteadiness parameter promotes it. The enhancement of inconstant thermal conductivity brings a positive influence on the thermal profile of fluid. Nusselt number drops against the thermal radiation & variable viscosity with a rates 4.50% and 25.88% correspondingly.

Abstract
Water reducing agent as an important admixture. It is used to decrease the initial water content in cement paste, improving its fluidity. Polycarboxylic acid water reducing agent (PCE) is a high-performance type with advantages such as low dosage, high water reduction rate, environmental friendliness, and a simple synthesis process. In this study, the third monomer (TPEG-SAA-SHES) was synthesized by modifying isopentenol polyoxyethylene ether (TPEG) with sodium hydroxyethyl sulfonate (SHES). Subsequently, a modified ether polycarboxylic acid-based water reducing agent (PCE-S) was synthesized with TPEG and acrylic acid (AA). The experimental conditions for the synthesis of PCE-S were optimized through orthogonal tests. The synthesized PCE-S showed a certain degree of improvement in the initial net slurry flow compared to PCE, with a maximum enhancement of 19.64%. The adsorption increased by 18.25% when the TSS dosage was 5%. PCE-S enhances the hydration products of cement, increasing the compactness of the structure. The product is environmentally friendly, safe, and durable, effectively reducing the dosage of additives and helping to cut costs. It lays the foundation for the next industrialized mass production.
Constructing Social Rights for the Poor
Authors: Leisering Lutz , Weible Katrin 
Published: August 2024

Abstract
Universal social rights are the core of the welfare state. However, in the Global South, until recently only the minority of workers in formal employment and public sector employees enjoyed the right to social security. This has changed since the 2000s through the rise of non-contributory ‘social cash transfers’ (SCT) for the poor. We investigate what entitlements to SCT have been created, and how close they come to human rights standards, based on a self-constructed dataset that covers the entire Global South. In conjunction with the analysis of SCT, the chapter also makes a more general contribution to the conceptual analysis of social rights. We argue that rights-based social security has a multidimensional and systemic nature that requires complex institutional designs, and these may be elusive in many countries of the Global South. First, multidimensionality: the right to social security is multidimensional, and social security must be designed in a way to meet human rights standards in all dimensions. Universal coverage, on which policymakers focus (‘universal social protection’), is only one of these dimensions. Second, systemic design: the ensemble of all programmes in a country (the national SCT system or ‘regime’) counts when it comes to assessing the human rights quality of social security. Therefore, the challenge is to design composite systems rather than only single programmes, on which policymakers focus. Third, institutional designs must be systemic also in normative terms: to be accepted as socially just, a national SCT system needs to combine diverse normative principles, and these must be rooted in citizens’ beliefs and attitudes as well as national politics—reference to broad global ideas such as universalism, inclusiveness, or even human rights is not enough. These three requirements are demanding, and we find that most SCT designs do not meet human rights standards. At the same time, we argue that the right to social security is only broadly defined and can be realized through a variety of institutional designs, thereby creating leeway for rights-based policies.
Gender in Welfare in the South
Authors: Sambo Cleopas Gabriel 
Published: August 2024

Abstract
This chapter focuses on gender in the implementation of social assistance programs, particularly cash transfers, in the Global South. While social cash transfers (SCTs) target the most vulnerable populations, they are designed not only for consumption soothing but also to address the underlying structures that perpetuate vulnerability and deprivation. In Zambia, where evidence of gendered poverty is prevalent, SCTs have prioritized women as recipients and ‘managers’ of the transfer within households, intending to foster their empowerment. However, current scholarship on the feminization of poverty suggests that merely centring women as transfer recipients without critically examining the norms contributing to their subjugation may hinder their progress towards empowerment. Drawing on interviews with individuals in poverty who receive cash transfers, this chapter examines the inherent contradictions between assumptions and realities of gender and empowerment in SCT households in Zambia. It interrogates the impact of gender norms embedded in this welfare programme on intra-household dynamics and the subsequent consequences for the empowerment of both men and women benefiting from such programmes. The chapter argues that the indiscriminate adoption of gender norms originating from the Global North, although perceived as progressive, often reinforces existing stereotypes and perpetuates gendered inequalities. It emphasizes the need for gender-sensitive social protection interventions encompassing broader livelihood strategies. It demonstrates the complexity of gender as a social category in welfare programming, particularly within the Global South.
Absenteeism and Delayed Enrollment

Published: August 2024

Abstract
Although attenuated learning progress was predicted in the early days of school closures, two major unanticipated challenges developed that have persistently impeded efforts to remediate learning losses. Chronic absenteeism, which is negatively associated with cognitive and psychosocial development as well as vocational achievement, has dramatically increased, even though schools have reopened. Chronic absenteeism rates have doubled in some areas, compared to 2019, and marginalized groups have been disproportionately affected. Schools have also suffered critical declines in student enrollment, and they have experienced delayed school entry; nationwide, more than 200,000 students have simply been lost to the system. These factors are known to impact educational and vocational attainment and long-term economic, health, and cognitive outcomes.
