The Effect of Motivation and Work Environment on Employee Performance at PT. Gapura Angkasa at Lombok International Airport

Advances in technology and information development affect a performance achievement. Employee performance can be influenced by motivation. In addition to motivation, employee performance is also influenced by the work environment. One of the main problems in human resources is how to improve the performance of employees. This study used a quantitative method by distributing questionnaires. The questionnaire in this study was distributed to 46 respondents. This study used data analysis techniques, namely instrument testing, classical assumption testing, regression analysis and hypothesis testing. The results of this study are that there is a joint influence between motivation and work environment on the performance of employees of PT. Gapura Angkasa at Lombok International Airport. This is reinforced by the results of the calculation of the coefficient of determination where R is 0.768 with R2 of 58.9%.

RIS-Enhanced Secure Transmission in MTC Networks With Finite Blocklength

In this paper, we propose a reconfigurable intelligent surface (RIS) assisted secure finite blocklength transmission framework in machine-type communications (MTC) networks, where the integration of millimeter-wave (mmWave) communication and non-orthogonal multiple access (NOMA) technology is considered to alleviate the problem of insufficient spectrum resources caused by massive MTC devices (MTCDs). For improving the ability of anti-eavesdropping, we aim to maximize the achievable sum secrecy capacity (SC) by jointly optimize the MTCDs’ transmission power, RIS phase coefficient and receive beamforming design. To handle the nonconvexity of the proposed optimization problem, we decouple it into three sub-problems, where the first two are solved by successive convex approximation (SCA) method. A minimum mean squared error successive interference cancellation (MMSE-SIC) scheme is proposed to tackle the receive beamforming problem for uplink NOMA networks. Furthermore, an alternating optimization based joint power, phase, and beamforming allocation (AO-JPPBA) algorithm is developed to implement joint optimization. Simulation results show that: 1) the security performance of the proposed AO-JPPBA is improved by 612.26% than the baseline scheme; 2) the proposed MMSE-SIC beamforming scheme is more effective in improving sum-SC of uplink NOMA networks; 3) RIS’s location has an obvious impact on sum-SC when considering eavesdroppers with strong wiretapping ability.

Use of the entropy approach in water resource monitoring systems

Effective management of water resources is possible only with an effectively organized monitoring system. After the emergence and development of information theory, the concept of information entropy found its place in the field of the development of water monitoring systems. The purpose of this work is to review research related to the construction of water monitoring systems and networks that applied the entropy theory in the design process. Methodology. Entropy terms used in the construction of water monitoring systems are summarized. Recent applications of the entropy concept for water monitoring system designs classified by precipitation are reviewed; flow and water level; water quality; soil moisture and groundwater. The integrated method of designing multifactorial monitoring systems is also highlighted. Results. The review analyzes studies and their implementation in the design of water monitoring networks based on entropy. The use of various methods of information theory and their adaptation for use in the design of monitoring networks is demonstrated, with the goal of network design methods being the selection of stations that provide the most information for the monitoring network, while being independent of each other. Through extensive testing, information theory has proven to be a reliable tool for evaluating and designing an optimal water monitoring network. Scientific novelty. This review focuses on studies that have applied information theory or information entropy to construct monitoring networks and systems. Information theory was developed by Shannon in the middle of the last century to measure the information content of a data set and was subsequently applied to solving water resources problems. To date, there are no review studies regarding the design of water monitoring networks based on the concept that entropy will be able to characterize the information specific to the monitoring station or monitoring networks. The main goal is to have the maximum amount of information. Practical significance. The optimal design of the monitoring network can be built based on the specified design criteria; however, the practical application of a new optimal monitoring network is rarely evaluated in a hydrological or other model. It is also important to identify the benefits of entropy-based network design to convince decision-makers of the importance of entropy-based approaches. The optimal network can be subjective, based on the choices made during the entropy calculation and the design method chosen, especially when additional objective functions are considered in the design. This applies to the method chosen to construct the optimal monitoring network, whether it is found using an iterative method where one station is added at a time, or a collection of stations that are added simultaneously. Research has also shown that data length, catchment scale, and the order can affect optimal network design. when using discrete entropy, it was shown that the binning method affects the final network design. Therefore, when selecting options based on the intended application of the monitoring network, a clear understanding and further research is needed to provide recommendations specific to water monitoring networks. In particular, more work is needed on the spatial and temporal scaling of the entropy calculation data to provide robust recommendations for decision-makers.

Resource Leveling using Two-Stage Scheduling Model for a Highway Construction Project at Jakarta

Project scheduling relates to series of activities that can have dependencies on each other during implementation. Each series of activities can cause problems from planning resource such as labor, costs, time, and heavy equipment to project implementation. The purpose of this study is to find out how to apply the two-stage scheduling optimization method for resource leveling, create a workforce histogram, and print the results of optimization resource scheduling in the form of LSM (Linear Scheduling Method) diagram. The existence of resource leveling is expected to avoid the problem of sudden resource needs or excessive resource accumulation. The biggest challenge in doing resource leveling is the increasing project duration. The two-stage scheduling optimization model has characteristics of CSP (Constraint Satisfaction Problem) so it will avoid increasing project duration. This optimization model will be carried out twice, assisted by using Microsoft Excel software with add-ins solver. The first stage will optimize the entire activities while the second stage will optimize the segment of non-controlling activities based on the CAP (Controlling Activity Path) that was formed during the first stage. The object of research used is a highway construction project at Jakarta. The results showed a new schedule with lower resource fluctuations.

Agricultural Water Quality Assessment and Application in the Yellow River Delta

Irrigation is the primary agricultural utilization of water resources worldwide, and it produces 36% of the food. The quality of irrigation water influences crop growth and food safety. The coastal river delta region supplies huge area lands for developing agriculture, and the irrigation in this area is composed of many resources for its special location. This study investigated the agricultural water with different resources and evaluated its quality in the Yellow River Delta. The water samples included irrigation water, underground water, and drainage water. The sampling points were designed in the typical areas of Kenli county and Guangrao county in Dongying city, which is the core area of the Yellow River Delta. Through testing the ions composition and the parameters of electrical conductivity (EC), pH, and so on, six evaluation methods were conducted to assess the water quality. The results suggested that the Yellow River water has good quality for irrigation or unconventional water utilization. The high concentration of Na+ and Cl− was the primary problem of the water resource. The rainfall was also another water resource supplement in this region. Therefore, developing saline water irrigation incorporated with salt-tolerant crop cultivation is a rational measure for improving coastal agriculture in the Yellow River Delta.

Between Support and Control: Quality Discourse on Informal Care in Austria

Ensuring quality of care is a key objective of welfare state action. In this context, also informal care is increasingly expected to meet quality standards. This article examines how and why quality assurance in informal care is demanded in political discourse, the problems of informal care that are addressed, and how different measures of quality assurance are legitimized and institutionalized. The analysis was carried out by means of a "framework analysis of political discourses". All parliamentary debates/queries around the topic of "quality assurance of informal care" for the period 1993-2021, as well as Austria's care provision reports (Pflegevorsorgebericht) 1994 to 2020 served as material. The results indicate an underdetermined concept of quality, which contains only vague ideas of what high-quality home care should look like. Quality assurance measures are primarily focused on supporting and relieving the burden on informal caregivers and thus address a resource problem. One of the aims of quality assurance is to maintain care "in one's own four walls" for as long as possible. In the context of a quality assurance discourse, the state mainly fulfils a supporting and controlling function, while urgent issues of care provision recede into the background.

Three types of calls admission control methods considering seek‐bar operation

AbstractMany network devices, such as a smartphones and tablets, and streaming services, such as YouTube and Netflix, have become widespread. This causes network‐bandwidth congestion, so users require stable and consistent communication quality. Call admission control (CAC) has been proposed to solve these bandwidth resource problems. Some CACs have been proposed in order to maintain QoS. However, these CAC does not assume user behaviour. If CAC assumes some user behaviour, optimal control parameter derived conventional CAC may change because traffic load change by considering user behaviour. This article assumes that arriving types of flows are of three types: narrowband flows, broadband flow without seek‐bar operation, and broadband flows with seek‐bar operation. Under this assumpution, two CAC methods with single threshold or two thresholds are proposed. With these methods, it is assumed that all arriving flows result in the same user satisfaction when accommodated in a network. Under this assumption, the maximum of each user satisfaction is the same as the maximum number of accommodated flows. Using the call loss probability characteristics of Method 1, the objective function in Method 2 is modified. By using the modified objective function, CAC can be realised while properly accommodating broadband users who have been excessively rejected.

A remote sensing image rotation object detection approach for real-time environmental monitoring

For the problems of resources and environment faced in sustainable development, the use of remote sensing image object detection technology is an effective means to detect and analyze this major problem. Aiming at the problems of low accuracy and slow detection speed of existing remote sensing image rotation object detection algorithms implemented based on Transformer, a remote sensing image rotation object detection method based on dynamic position information Transformer is proposed. Firstly, to improve the detection accuracy, the cross-attention operation of the decoder is improved, and the obtained results are iteratively updated with the position information of the object queries and used as the initial object queries for the next decoder; secondly, to improve the robustness of the network for remote sensing image object detection, the data processing method of image pyramid is designed; Finally, a rotating IoU matching loss function more suitable for oriented object detection is introduced to improve the accuracy of matching the predicted boxed to the true boxed. The detection algorithm proposed in this paper is experimentally verified on DOTA and SSDD datasets, and the average detection accuracy is 73.70% and 90.3%, respectively, which effectively improves the average detection accuracy of Transformer-based rotating object detection algorithm in aerial remote sensing images and has better real-time detection performance.

UV resistance and biodegradation of PLA-based polymeric blends doped with PBS, PBAT, TPS

The design of new biodegradable polymers is important for solving the fossil resource and environmental pollution problems associated with conventional plastics. New PLA-based mixtures with the addition of PBAT, PBS and TPS, with different contents, were prepared to investigate their behavior after accelerated aging, as well as their potential for the biodegradation process. Their mechanical properties, mass, hardness, morphology, gloss and color change during UV irradiation progress, have been investigated. The samples were exposed to UV radiation for 21 d, their accelerated aging properties, were assessed weekly and compared with the non-aged samples. The degree of disintegration was determined after soil burial. The results showed that the mechanical properties, especially formability, as well as gloss and color, changed significantly after accelerated aging. All tested matrices are degradable, as shown by soil burial tests. Testing the stability of the functional properties of biodegradable plastics, which are assessed by end users, is important for the wider use of these plastics.

Evaluation and obstacle factors of marine resources and environment carrying capacity in Beibu Gulf Urban Agglomeration

With the strong support of the Chinese government, the Beibu Gulf Urban Agglomeration has responded positively to the national call to vigorously develop the marine economy. However, a series of marine resource and environmental problems such as over-exploitation of marine resources and excessive discharge of marine pollutants in the Beibu Gulf Urban Agglomeration has also arisen along with the rapid development of the marine economy, limiting the space for the development of the marine economy in the Beibu Gulf Urban Agglomeration. Based on the panel data of seven coastal cities in the Beibu Gulf urban agglomeration from 2011-2021, the DPSIR model was used to construct a marine resources environmental carrying capacity evaluation index system including five dimensions of driving force, pressure, state, impact and response, and the TOPSIS model with combined weighting was used to make a comprehensive evaluation of the marine resources carrying capacity of the Beibu Gulf urban agglomeration, and then the barrier degree model was used to explore the barriers to the carrying capacity of marine resources and environment in the Beibu Gulf Urban Agglomeration. The empirical results show that, on the whole, the marine resources and environment carrying capacity of the seven coastal cities in the Beibu Gulf Urban Agglomeration show an upward trend. From the situation of each subsystem, the pressure subsystem and response subsystem have greater evaluation values, while the evaluation of the driving force, state, and influence subsystem needs to be improved; from the analysis of obstacle factors, the main single indicator obstacle factors include per capita coastline length, total import and export volume, and port cargo throughput, etc. The status subsystem is the main classification indicator barrier factor affecting the improvement of the marine resource and environmental carrying capacity of the Beibu Gulf Urban Agglomeration. Based on the results of the empirical analysis, corresponding suggestions are put forward.

An Enhanced Deep Reinforcement Learning-Based Global Router for VLSI Design

Global routing is a crucial step in the design of Very Large-Scale Integration (VLSI) circuits. However, most of the existing methods are heuristic algorithms, which cannot conjointly optimize the subproblems of global routing, resulting in congestion and overflow. In response to this challenge, an enhanced Deep Reinforcement Learning- (DRL-) based global router has been proposed, which comprises the following effective strategies. First, to avoid the overestimation problem generated by Q -learning, the proposed global router adopts the Double Deep Q -Network (DDQN) model. The DDQN-based global router has better performance in wire length optimization and convergence. Second, to avoid the agent from learning redundant information, an action elimination method is added to the action selection part, which significantly enhances the convergence performance of the training process. Third, to avoid the unfair allocation problem of routing resources in serial training, concurrent training is proposed to enhance the routability. Fourth, to reduce wire length and disperse routing resources, a new reward function is proposed to guide the agent to learn better routing solutions regarding wire length and congestion standard deviation. Experimental results demonstrate that the proposed algorithm outperforms others in several important performance metrics, including wire length, convergence performance, routability, and congestion standard deviation. In conclusion, the proposed enhanced DRL-based global router is a promising approach for solving the global routing problem in VLSI design, which can achieve superior performance compared to the heuristic method and DRL-based global router.

The purposeof the proposed research is to create a metaphysical portrait sketch of Melitopol in the symbolic circle "honey -milk -water" in the context of attracting symbolic resources problem in tourism.In an intensive way, and following thestrengtheningof homo viator phenomenon in the global world, research in the touristic field and philosophy of tourism are increasingly turning their attention to the "internal resource", including in this concept, in addition to natural and cultural-historical, also symbolic resource. The work uses such methods as dialectical and metaphysical, the principle of comprehensiveness of research, the general logical method, and other methods of scientific research. Tourist legend as an applied direction can become an effective marketing mechanism, as a result of which it is possible, using a symbolic resources variety and tools, to create humanitarian and social development perspectives, agreed and identified through analysis of mythological structures and conceptual shells for harmonious and effective development of these territories. In this aspect, tourism as oneof the mass culture branches will produce tourist flows directed to previously elaboratedterritorial brands.

Performance Analysis of Automatic Hidden Ligthpaths in Multi-Layer Networks

The problem of resource provisioning in multi-layer networks is an important issue. We discuss and analyze resource provisioning in terms of the visibility of optical resources for the virtual layer in a network. In this context, we propose the diversification of the optical spectrum in such a way that some resources are hidden for the virtual layer and used when needed. We introduce and investigate automatic hidden lightpaths to improve resource utilization in multi-layer networks. Our solution uses a software-defined networking concept to automatically set up and release hidden lightpaths, which are not visible at the network layer. We evaluate and analyze two main approaches to resource provisioning in terms of the blocking probability. Future research should focus on resource diversification and the usage of the hidden elastic optical spectrum in modern networks as a promising solution.

Edge Computing Task Offloading for Environmental Perception of Autonomous Vehicles in 6G Networks

The most basic requirement for autonomous vehicles is accurate environmental perception. However, the lack of onboard computing resources makes it difficult for such a vehicle to process all environmental information. Through the edge computing technology and 6G networks, vehicles can offload computing tasks to edge servers for execution, which alleviates the problem of insufficient onboard resources. The environmental perception task offloading problem for autonomous vehicles is studied. The purpose is to improve the environmental perception quality through reasonable task offloading. After assigning dynamic priorities to tasks generated by autonomous vehicles, the multi-vehicle and multi-server task offloading process is abstracted as a Markov decision process, and an offloading decision algorithm based on deep reinforcement learning is designed to select edge nodes for task execution to obtain better long-term benefits. The earliest deadline first algorithm is improved to consider the deadline and priority of each task, allowing the edge node to complete more high-priority tasks within the specified time. Experimental results show that the proposed method can guarantee the basic environmental perception requirements of every vehicle, and performs better than existing methods in terms of the total priority of the discarded tasks in each scheduling period and the completion rate of key tasks.

Environmental Risks of Water Resources in the Belarusian Polesie

The article is devoted to the problems of water resources in Belarusian Polesie. Surface water resources analysis was carried out for the different types of runoffs. There was a significant decrease in maximum spring runoff and a decrease in the average annual runoff. A statistically significant increase in the minimum winter runoff is observed for the rivers of the Pripyat River basin. For the minimum summer–autumn runoff, there was no unambiguous trend in the runoff change. Quality of natural waters analysis included investigation of the annual concentrations of priority substances in the water of some rivers in Polesie for dissolved oxygen, phosphates, nitrogen, petroleum products, copper, zinc, etc. In general, there have been trends toward a pollution decrease in the Polesie Rivers. The possible consequences of changes in river runoff due to climate change are considered. The priority tasks of research on solving the Polesie water problems are outlined.

Complex modifier based on alumina cement and pozzolanic addition

Introduction. The most popular binders for the concrete production are inorganic binders. Composite binding agents (CB) based on Portland cement are increasingly being used to produce high-quality concretes, improve the efficiency of cement use in concrete, as well as to solve the problem of energy and resource saving by reducing the amount of clinker inthe cement composition.
 Materials and methods. The properties of a composite binder consisting of Portland cement, alumina cement, natural gypsum and an active mineral additive, were studied. The Box – Wilson experiment design method was used. To determine the standard consistency of the cement paste, the standard test method was chosen according to GOST 310.3–76.The research was carried out in the laboratory of the Department of Building Materials Science of Moscow State University of Civil Engineering.
 Results. It was found that with the introduction of additives normal density of the cement paste increases. This is explained by the fact that the composition of the complex additive includes tripoli and alumina cement. Tripoli is a natural porous rock with a highly developed surface. Alumina cement has a great influence on the normal density and setting time as it reacts very quickly to form new hydration compounds in the first minute from the start of mixing the binder with water.The dependence of normal density on the quantitative content of additives is presented as a regression equation and surface image.
 Conclusions. Based on the results of this study, in the future the authors will continue to study the properties of binders based on a complex expanding and pozzolanic addition.

Initiatives on exploring the mechanism of eco‐hydrological response to land surface change and adaptive regulation in the Yellow River Basin

AbstractThe Yellow River Basin faces water scarcity and ecological fragility. Changes on the land surface, characterized by large‐scale soil and water conservation measures, have a significant impact on river runoff and ecological environment. However, there are still great uncertainties in the scientific understanding of the mechanisms by which multiple driver impact eco‐hydrological processes due to the diversity of land surfaces and the complexity of the coupling processes. As an international scientific frontier on interdisciplinary studies in climatology, hydrology, ecology, and other related fields, it is significant to study the mechanisms and assess the impacts of land surface change on eco‐hydrological risk to support ecological restoration plan and sustainable water resources utilization in the Yellow River Basin. Taking the Yellow River Basin as the study area, this study proposes several important research initiatives, focusing on addressing the ecological and water resources problems in the Loess Plateau. These initiatives include (1) to quantify the individual effect of land surface elements (e.g., vegetation, terraces, and check dam) and reveal the nonlinear driving mechanisms of multiple drivers on eco‐hydrological processes; (2) to construct a distributed eco‐hydrological model that couples dynamic land surface features, and simulate eco‐hydrological processes in a changing environment; (3) to improve the ecological risk assessment indicator system and methods for assessing the impacts of land surface changes on eco‐hydrological synergistic functions and ecological risk; (4) to establish an ecological regulation model based on multiobjective game theory and adopt an adaptive regulation mode for ecological risk management. The research could enrich the scientific understanding and theory of eco‐hydrology, and prompt disciplinary studies of ecology, hydrology, climatology, and other fields. The expected academic achievements will innovate eco‐hydrological simulation and assessment techniques in a changing environment, and strongly support the implementation of the national strategy for ecological protection and high‐quality development in the Yellow River Basin.
