This study aimed to examine the mechanisms underlying digital game usage behavior by applying the Theory of Planned Behavior and the Balance Theory. It investigated the influences of attitude, subjective norms, and perceived behavioral control on the intention to use digital games, as well as the differences in the application of the Theory of Planned Behavior model based on the balance state among individuals, significant others, and digital games. A total of 315 responses from adult PC game users were collected through an online survey conducted from October 21 to 25, 2021, and were analyzed using multiple regression analysis. The results revealed that attitude and perceived behavioral control had a significant positive impact on the intention to continue using digital games, while subjective norms did not exert a significant influence. By categorizing groups into balanced, unbalanced, and imbalance states based on the balance relationship, the application of the Theory of Planned Behavior model showed that in the unbalanced and imbalance groups, both perceived behavioral control and attitude had a positive impact on the intention to continue using digital games. However, in the balanced group, attitude only had a positive impact on the intention to continue game usage. This study contributes to understanding digital game users by examining both individual psychological factors and the influence of others on digital game usage behavior.

Along with the development of creative building design ideas, how to effectively sign design concepts is also an important consideration on environmental design. The research goals established in order to solve these problems are to develop structures of sign design and analyze the cases of it. This paper explains structures of sign design in two ways: the compositional elements of signs and the relationships of visual perception. Among various relationships among sign design compositional elements this study uses relationships based on the Gestalt theory, the balance theory by Rudolf Arnheim, and the optical away theory by Gibson. The design principles investigated on the basis of the visual perception theories include the relationships between compositional elements and background space, visual weight balance, horizontal and vertical balances, grouping, and visual layout patterns

Basin evapotranspiration is the result of water balance and energy balance, which is affected by climate and underlying surface characteristics, the process is complex, and spatial and temporal variability is large, the evapotranspiration estimation of river basin is an important but difficult problem in the field of hydrology, over the years, many scholars devoted to the basin actual evapotranspiration estimation and achieved excellent results. We discuss Budyko coupled water-energy balance theory and evaporation paradox, then use the Fu's equation to estimate actual evapotranspiration yearly in different areas with different dryness. The result shows that Fu's equation has high precision for estimating evapotranspiration yearly in our selected study area, and the estimation result has higher precision in the area with high dryness. Then, we propose an improved formula which can be used to estimate actual evapotranspiration monthly. Furthermore, we found that the parameter in the formula reflects general conditions of underlying surface and it is affected by several factors, at last, we tried to propose the calculation formula. The study indicates that Fu's equation provides a reliable method for evapotranspiration estimation in dry regions as well as semi-humid and semi-arid regions, which has great significance for forecasting river basin water resources and inquiring into ecological water requirement.

This study was conducted for the purpose of comparing the advertising effect of Korean companies and Vietnamese domestic companies by applying the balance theory to Vietnamese consumers emerging as a new market for Korean companies. An experiment was conducted on female university students, and cognitive, emotional, and behavioral responses to advertisements in the two countries were investigated. The results showed that there was no difference in the cognitive dimension of Vietnamese consumers' evaluation of advertisements in Korea and Vietnam, but there is a difference in the emotional dimension and the behavioral dimension. This study contributed theoretically to the possibility of applying the balance theory to the study of international advertising effects, and the implications of international advertising of Korean companies in the underdeveloped markets were discussed.

As a solution to spectrum under-utilization problem, Cognitive radio (CR) introduces a dynamic spectrum access technology. In the area, one of the most important problems is how secondary users (SUs) should choose between the available channels, which means how to achieve load balancing between channels. We consider spectrum load balancing problem for CR system in frequency domain and especially in time domain. Our objective is to balance the load among the channels and balance the occupied time length of slots for a fixed channel dynamically in order to obtain a user-optimal solution. In frequency domain, we refer to Dynamic Noncooperative Scheme with Communication (DNCOOPC) used in distributed system and a distributed Dynamic Spectrum Load Balancing algorithm (DSLB) is formed based on DNCOOPC. In time domain, Spectrum Load Balancing method with QoS support is proposed based on Dynamic Feed Back theory and Hash Table (SLBDH). The performance of DSLB and SLBDH are evaluated. In frequency domain, DSLB is more efficient compared with existing Compare_And_Balance (CAB) algorithm and gets more throughput compared with Spectrum Load Balancing (SLB) algorithm. Also, DSLB is a fair scheme for all devices. In time domain, SLBDH is an efficient and precise solution compared with Spectrum Load Smoothing (SLS) method.

Along with the development of creative design ideas, how to effectively present design concepts is also an important consideration on housing plan process. This could consequently make it possible to automate presentations. In spite of such needs of presentations any significant efforts for the systematic design presentation have not been made yet. The research goals established in order to solve these problems are to develop structures of presentation and analyze the cases of it. This paper explains structures of housing plan presentations in two ways: the compositional elements of panel presentations and the relationships among the elements. The elements include a project title, a synopsis, design concepts, building layouts, floor plan1 and 2, longitudinal and latitudinal elevations, sections, projection and perspective views, and model photographs. Among various relationships among panel compositional elements this study uses relationships based on the Gestalt theory, the balance theory by Rudolf Arnheim and the optical array theory by Gibson. The relationships investigated on the basis of the visual perception theories include the relationships between compositional elements and background space, visual weight balance, horizontal and vertical balances, grouping, and visual layout patterns.

Given that most of the link prediction algorithms for signed social networks can only complete sign prediction, a novel algorithm is proposed aiming to achieve both link prediction and sign prediction in signed networks. Based on the structural balance theory, the local link tightness and global link tightness are defined respectively by using the structural information of paths with the step size of 2 and 3 between the two nodes. Then the total similarity of the node pair can be obtained by combining them. Its absolute value measures the possibility of the two nodes to establish a link, and its sign is the sign prediction result of the predicted link. The effectiveness and correctness of the proposed algorithm are verified on six typical datasets. Comparison and analysis are also carried out with the classical prediction algorithms in signed networks such as CN-Predict, ICN-Predict, and PSNBS (prediction in signed networks based on balance and similarity) using the evaluation indexes like area under the curve (AUC), Precision, improved AUC', improved Accuracy', and so on. Results show that the proposed algorithm achieves good performance in both link prediction and sign prediction, and its accuracy is higher than other algorithms. Moreover, it can achieve a good balance between prediction accuracy and computational complexity.

This study attempted to explore the experience related to the work-family balance of working moms during the COVID-19 period. To this end, in-depth interviews were conducted by recruiting 17 part-time and full-time working moms with at least 1 child under the age of 13. As a result of analyzing the data using the method of grounded theory, 106 concepts, 50 subcategories, and 24 categories were derived. The central phenomenon that working moms experienced in the process of work and family balance were "physical and emotional exhaustion", "anxiety and guilt about not doing well in situations of role conflicts between various roles", "job crisis experienced by working mothers" and "deepening family conflicts". The process of working moms overcoming the central phenomenon and achieving work-family balance was identified as five stages: the 'shock and confusion stage', the 'struggling stage', the 'actively coping and making compromise stages', the 'acceptance stage', and the 'post-traumatic growth stage'. Based on these results, discussions on the work-family balance of working mothers during the COVID-19 period was dealt as well as suggestions for follow-up studies.

Balance function is one of the joint factors to determine fall in risk theory. It helps to moderate the progression and riskiness of falls for detecting balance and fall risk factors. Nevertheless, the objective measures for balance function require expensive equipment with the assessment of any expertise. We establish the existence and uniqueness of a multi-order fractional differential equations based on ${\psi}$-Hilfer operator on time scales with balance function. This class describes the dynamic of time scales derivative. Our tool is based on the Schauder fixed point theorem. Here, sufficient conditions for Ulam-stability are given.

Based on the space vector pulse width modulation (SVPWM) theory, this paper realizes an easier SVPWM strategy, which is equivalently implemented by CBSPWM with zero-sequence voltage injection. The traditional SVPWM strategy has no effect on controlling the neutral-point voltage balance. In order to solve the neutral-point voltage unbalance problem for neutral-point-clamped (NPC) three-level inverters, this paper proposes a neutral-point voltage balance controller. The proposed controller realizes controlling the neutral-point voltage balance by dynamically calculating the offset superimposed to the three-phase modulation waves of an equivalent SVPWM strategy. Compared with the traditional SVPWM strategy, the proposed neutral-point voltage balance controller has a strong ability to balance the neutral-point voltage, has good steady-state performance, improves the output waveforms quality and is easy for digital implementation. An experiment has been carried out on a NPC three-level inverter prototype based on a digital signal processor-complex programmable logic device (DSP-CPLD). The obtained experimental results verify the effectiveness of the proposed neutral-point voltage balance controller.
