Authors: He Jiajun , Fan Xin , Chen Lin , Chen Haoruo , Luo Jin , Huang Zirui
Published: June 2023

With the decisive results of poverty alleviation in China, figuring out how to consolidate the results and transform them into the driving force of rural revitalization is an important adjustment for rural revitalization and high-quality development. The efficiency of policy implementation as well as the sustainable development of the areas out of poverty are both reflected in rural households’ satisfaction with the ex-suit poverty alleviation policy for relocation. Based on survey data collected from 293 households in County M, Sichuan Province, this paper selects 23 indicators of satisfaction with post-relocation support policies from livelihood capital, political trust, policy participation, and public service perception. On this basis, we use the multinomial logistic model to analyze the impact of each influencing factor on the post-relocation support policy’s satisfaction degree for rural households. The results show that the satisfaction degree of relocated households with post-relocation support policies is upper-middle. Among the livelihood capital of relocated households, the proportion of non-agricultural income, cultivated land area, infrastructure conditions, number of family workers, and number of civil servants are all factors that positively affect policy satisfaction. In addition, with regard to relocating households’ engagement in political trust, policy participation, and public service perception, it should be pointed out that policy results trust, policy understanding, opinions expressed, local government, back-up personnel, policy process, and support funds all have appreciably positive effects on policy satisfaction. These evaluation results can serve as a reference for the revision of post-relocation support policies in China and other developing countries.
Why Don’t Scientists Follow the Water Footprint Assessment Manual? Example of One Study
Authors: Ansorge Libor
Published: June 2023

A recently published study by Parra-Orobio et al. looked at a water footprint assessment in low-income urban neighborhoods from developing countries; specifically, this is a case study of the Fátima site in the municipality of Gamarra, Colombia. However, that study deviates significantly from the water footprint methodology described in the Water Footprint Assessment Manual. Therefore, the results of the study cannot be compared with similar studies. In this Letter to the Editors, different parts of the application of the water footprint methodology used in the mentioned study are analyzed and several main deviations from the standard water footprint methodology are pointed out. It is, therefore, suggested that the authors of the article “Assessment of the Water Footprint in Low-Income Urban Neighborhoods from Developing Countries: Case Study Fátima (Gamarra, Colombia)” should expand or modify this article to clarify any deviations from the standard water footprint methodology.

Published: June 2023

The transportation industry plays a key role in reducing urban emissions of air pollutants and energy consumption. The transition from traditional fossil fuel-based vehicles (TFFBVs) to new energy vehicles (NEVs) is critical to China’s strategic goal of reaching peak carbon dioxide (CO2) emissions before 2030 and achieving carbon neutrality before 2060. On the basis of the environmental status and development of NEVs in Chongqing in 2020, we designed scenarios for replacing TFFBVs in Chongqing with NEVs according to targets such as the number of proposed NEVs in China’s 14th Five-Year Plan. Following this, we evaluated the environmental and health benefits of NEVs and their monetary value using exposure–response and disease–cost methods. Replacing 18%, 35%, and 50% of TFFBVs with NEVs can create health benefits of approximately CNY 11.391 billion, CNY 21.696 billion, and CNY 30.443 billion, accounting for 4.56%, 8.68%, and 12.18%, respectively, of Chongqing’s GDP in 2020. These amounts exceed the cost of government subsidies. Greater health benefits were derived from reducing the toxic emissions of nitrogen dioxide (NO2); the reduction in deaths caused by cardiovascular diseases created the best benefits for health endpoints, exceeding a 59% reduction in all three scenarios. Our study provides empirical support for promoting NEVs.

Authors: Mensah Leviticus , Bein Murad Abdurahman
Published: June 2023

The study aimed to compare the effect of sound corporate governance on manufacturing companies in South Africa, Nigeria, and Ghana on financial performance. The study used a purposive sampling method to select 60 manufacturing companies, of which twenty-nine (29) were from South Africa, 17 were from Nigeria, and 14 were from Ghana. The study employed GMM and FMOLS to estimate the effect of corporate governance on the firm’s financial performance. According to the study, South Africa has the longest average board tenure at 7.85 years, followed by Nigeria at 4.7 years and Ghana at 3.9 years. The average board tenure was found to have a positive and statistically significant effect on the return on invested capital (ROIC) of the firms in South Africa and Ghana, and a positive and statistically insignificant effect was found for the firms in Nigeria. The study indicated that the firms in South Africa have the highest percentage of female directors at 24.26%, followed by Ghana at 17.8% and Nigeria at 17.3%. The study showed that female representation on the corporate board has a positive and statistically significant effect on all firms’ return on net operating assets (RONOA). The study provides policy implications for shareholders, boards of directors, and other stakeholders by enabling them to build confidence in the corporate governance structure of manufacturing companies in the three countries.

As the research on national corruption continues to expand, village corruption research has gained attention in the public eye in the last 10 years. A growing number of researchers have called for a more extensive discussion on village corruption. In response, this paper conducts a comprehensive review of village corruption research to portray the trend and evolvement of village corruption literature over the past 30 years and also to find out the dominant elements of village corruption research for providing future research agendas aimed at addressing village corruption. The study analyzed 158 articles from the Web of Science database. The data were analyzed first using two bibliometric software packages, Histcite 12.3.17 and VOSviewer 1.6.19, and then by content analysis to obtain a more comprehensive result. The findings overlay visualization indicates that the research on village corruption has evolved from African countries to Asia. Studies from the economics and politics fields are the most common research areas on village corruption since 1992, followed by research on management. Research in the accounting and information technology fields remain relatively scarce. The institutions based in the USA have dominated publications, and World Development is the most influential journal. This research provides future research agendas as smart villages on corruption eradication and village sustainability.

Authors: Liang Rui , Zheng Xichuan , Liang Jia , Hu Linhui
Published: June 2023

We aim to create a feasible quantitative method to calculate the energy efficiency of building designs that are carbon-neutral and to develop a workable way of calculating energy efficiency in buildings that achieve carbon neutrality and the system for such a building’s design energy efficiency function. This paper first clarifies the idea of the design energy efficiency function for a carbon-neutral building over its whole life cycle. Subsequently, through the efficient analysis of carbon-neutral design dimension measures, this paper summarizes and integrates the mature theories of various disciplines, puts forward the energy efficiency function model of carbon-neutral design background, propulsion, and coverage, and implements the energy efficiency function model of carbon-neutral design in the whole life cycle of buildings. The index value of a building’s carbon emission factor is established based on the carbon accounting factor published by the Intergovernmental Panel on Climate Change, and a carbon neutrality energy efficiency model for buildings over the duration of their whole life cycle is constructed. The results were as follows. 1. Technology energy efficiency is far better than scale energy efficiency and comprehensive energy efficiency. 2. The better the energy efficiency value inside the building stage, the less consumption and the higher the production. 3. Construction is when technical energy is used the least. This paper refers to a systematic design method that makes the level of building carbon neutrality design technologically advanced with the aid of all types of big data related to the building life cycle and various innovative design theories in order to fully represent the fundamental level, development potential, and the effectiveness of choosing the strategy of building carbon neutrality.
Novel Analysis between Two-Unit Hot and Cold Standby Redundant Systems with Varied Demand
Authors: Malhotra Reetu , Alamri Faten , Khalifa Hamiden
Published: June 2023

Decisive applications, such as control systems and aerial navigation, require a standby system to meet stringent safety, availability, and reliability. The paper evaluates the availability, reliability, and other measures of system effectiveness for two stochastic models in a symmetrical way with varying demand: Model 1 (a two-unit cold standby system) and Model 2 (a two-unit hot standby system). In Model 1, the standby unit needs to be activated before it may begin to function; in Model 2, the standby unit is always operational unless it fails. The current study demonstrates that the hot standby system is more expensive than the cold standby system under two circumstances: a decrease in demand or the hot standby unit’s failure rate exceeding a predetermined threshold. The cold standby system’s activation time is at most a certain threshold, and turning both units on at once is necessary to handle the increasing demand. In that case, the hot standby will be more expensive than the cold standby system. The authors used semi-Markov and regenerative point techniques to analyze both models. They collected actual data from a cable manufacturing plant to illustrate the findings. Plotting several graphs and obtaining cut-off points make it easier to choose the standby to employ.

Published: June 2023

Soil pollution is a global environmental problem. Nanoscale zero-valent iron (nZVI) as a kind of emerging remedial material is used for contaminated soil, which can quickly and effectively degrade and remove pollutants such as organic halides, nitrates and heavy metals in soil, respectively. However, nZVI and its composites can enter the soil environment in the application process, affect the physical and chemical properties of the soil, be absorbed by microorganisms and affect the growth and metabolism of microorganisms, thus affecting the ecological environment of the entire soil. Because of the potential risks of nZVI to the environment and ecosystems, this paper summarizes the current application of nZVI in the remediation of contaminated soil environments, summarizes the various factors affecting the toxic effects of nZVI particles and comprehensively analyzes the toxic effects of nZVI on microorganisms, toxic mechanisms and cell defense behaviors to provide a theoretical reference for subsequent biosafety research on nZVI.

Industrial areas play an important role in the urban ecosystem. Industrial site environmental quality is linked to human health. Soil samples from two different cities in India, Jamshedpur and Amravati, were collected and analyzed to assess the sources of polycyclic aromatic hydrocarbons (PAHs) in industrial areas and their potential health risks. The total concentration of 16 PAHs in JSR (Jamshedpur) varied from 1662.90 to 10,879.20 ng/g, whereas the concentration ranged from 1456.22 to 5403.45 ng/g in the soil of AMT (Amravati). The PAHs in the samples were dominated by four-ring PAHs, followed by five-ring PAHs, and a small percentage of two-ring PAHs. The ILCR (incremental lifetime cancer risk) of the soil of Amravati was lower compared to that of Jamshedpur. The risk due to PAH exposure for children and adults was reported to be in the order of ingestion > dermal contact > inhalation while for adolescents it was dermal contact > ingestion > inhalation in Jamshedpur. In contrast, in the soil of Amravati, the PAH exposure path risk for children and adolescents were the same and showed the following order: dermal contact > ingestion > inhalation while for the adulthood age group, the order was ingestion > dermal contact > inhalation. The diagnostic ratio approach was used to assess the sources of PAHs in various environmental media. The PAH sources were mainly dominated by coal and petroleum/oil combustion. As both the study areas belong to industrial sites, the significant sources were industrial emissions, followed by traffic emissions, coal combustion for domestic livelihood, as well as due to the geographical location of the sampling sites. The results of this investigation provide novel information for contamination evaluation and human health risk assessment in PAH-contaminated sites in India.
Transgenic Drosophila to Functionally Validate Fall Armyworm ABCC2 Mutations Conferring Bt Resistance

Published: June 2023

The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith; Lepidoptera: Noctuidae) is an invasive agricultural pest with a global distribution, causing major crop losses annually. Its control strategies largely rely on chemical insecticides and transgenic crops expressing Bacillus thuringiensis insecticidal proteins (Cry and Vip toxins); however, the development of high resistance poses a significant issue. The ATP-binding cassette transporter C2 (ABCC2) has been linked to Cry toxin pore formation, acting as a receptor of some Cry toxins. Recently detected mutations in the SfABCC2 gene in extracellular loop 4 (ECL4) have been associated with Bt toxin resistance in FAW. In the present study, we expressed the SfABCC2 gene in Drosophila melanogaster, a species normally unaffected by the Bt toxins. We demonstrate that susceptibility can be introduced by the ectopic and tissue-specific expression of wildtype SfABCC2. Next, we introduced mutations into ECL4—both individually and in combination—that have been recently described in Brazilian FAW and functionally validated by toxicity bioassays against the foliar Bt product Xentari. Our results provide an efficient demonstration of the suitability of transgenic Drosophila for validating FAW ABCC2 resistance mutations in ECL4 against Bt toxins, and potential cross-resistance issues between closely related proteins that use ABCC2.

Published: June 2023

Understanding variations in contaminant concentrations and exploring their driving factors are essential for pollution control and water environment improvement. The Huaihe River Basin, as an important region in the eastern region of China, has attracted much attention to its water environment issues in recent years. Therefore, an in-depth analysis of spatiotemporal patterns of water quality parameters was carried out on the Huaihe River–Hongze Lake system, for the period 1998–2018, using the Mann–Kendall test (MKT) and wavelet transforms (WTs). Significant decrease trends of ammonia nitrogen (AN) and chemical oxygen demand (COD) concentrations were detected in the Huaihe River (HR) before 2008 using the MKT. High concentration in the contaminant load was a result of the effect of increased construction and decreased forest on increasing input of pollutants during this period. The results of the WT showed how factors (e.g., streamflow and water temperature), except land use, affect the variations in AN and COD concentrations. The comparison of spatiotemporal patterns of AN and COD between the HR and Hongze Lake (HL) showed their differences in contaminant transport regimes. The contaminants were rapidly transported downstream along the HR with high streamflow during the wet season, while these in the HL were less responsive due to the long residence time of the water body. In addition, rebounds of contaminant concentrations occurred many times at the confluence between the HR and the HL due to strong river–lake interactions, especially in the flood season. These results have implications for future water environment management in the Huaihe River Basin and in similar settings worldwide.

Published: June 2023

The management and disposal of wastewater treatment sludge can be a costly and resource-intensive process. To provide a cost-effective and sustainable alternative, Sludge Treatment Wetlands (STW) have emerged as a viable solution for enhancing sludge quality through dewatering and biodegradation. In this study, the effectiveness of a full-scale STW for stabilizing and dewatering digested microalgal biomass from a domestic and agricultural wastewater treatment system was evaluated. The properties of the treated digestate in the STW were assessed after 35 weeks of operation and a resting period of 4 weeks. The dry matter content was found to be 12.8%, and the average macronutrient content was K: 3.8 mg/g DW, P: 4.9 mg/g DW, and Ca: 95 mg/g DW. The highest contents of micronutrients were for Fe: 7.8 mg/g DW and Mg: 7.6 mg/g DW, while heavy metals and pathogen contents were below the EC limits for sewage sludge reuse in agriculture. The STW was found to be a cost-effective and environmentally friendly option for treating mixed wastewater-based sludge for land application. The STW outperformed reference systems using centrifuge dewatering techniques, particularly in terms of eutrophication potential and acidification potential. However, the STW’s economic performance was slightly worse than that of the dewatering system in terms of unit production cost. This study is the first in the literature to investigate the use of STW for treating digested microalgae and its possible reuse in arable land, suggesting that STW infrastructures have great potential for the development of sustainable and eco-friendly sludge treatment technologies.
Comparison of Residual Kidney Function Assessment Between the Hemodialysis 2-Day and 3-Day Interdialytic Interval
Authors: Wong Gabriella , Zimbudzi Edward , Kerr Peter G.
Published: June 2023

Key Points

There was no detected difference in measured residual kidney function between the short and long interdialytic intervals.

Sample collection for assessment of residual kidney function can occur at either interdialytic interval without concerns surrounding comparability of results.

Background

Residual kidney function (RKF) is a dynamic marker having been shown to demonstrate fluctuations over successive days of the interdialytic interval. This study compares measured RKF between the long interdialytic interval (LIDP) and short interdialytic interval (SIDP).

Methods

This was a prospective cohort study. Thirty-four clinically stable, ambulatory facility hemodialysis patients were recruited. Urine samples collected in the last 12 hours of each interdialytic interval were paired with a blood test at the conclusion of each 12-hour interval to evaluate measured RKF through a mean of urinary urea and creatinine clearances. The paired Student t test and the Wilcoxon matched pairs signed-ranks were used, respectively, to compare differences in assessed mean and median RKF.

Results

Although average serum creatinine (607±219 µmol/L versus 547±192 µmol/L, P = <0.01) and serum urea concentrations (25±15 mmol/L versus 19±5 mmol/L, P = 0.01) were higher in the LIDP compared with SIDP, there was no statistically significant difference in urine volume (630±460 ml versus 520±470 ml, P = 0.06), urine urea (116±49 mmol/L versus 118±90 mmol/L, P = 0.87), or urine creatinine (7816±3943 µmol/L versus 8926±5752 µmol/L, P = 0.06) concentrations. On the whole, there was no significant difference in assessed RKF between the LIDP and SIDP (mean 8±6 ml/min versus 6±4 ml/min, P = 0.24; median 6.3 [3.2–10.4] versus 5.8 [3.8–8.9], P = 0.13).

Conclusions

There was no statistically significant difference observed in assessed RKF between the LIDP and SIDP. Measured RKF through samples collected from the LIDP and SIDP is comparable.
Evaluating Extension Program Impacts Through Comparison of Knowledge and Behavior of Extension Clientele Versus Others
Authors: Wang Tong
Published: June 2023

A new method for evaluating the influence of Extension programming involves exploring whether Extension clientele differ from others in knowledge and behavior related to a particular topic. Analysis of South Dakota farm survey data allowed for the assessment of potential impacts of Extension through comparison of knowledge and adoption regarding soil conservation practices among farmers who did and did not use Extension. Results suggest that, controlling for some farmer and farm characteristics, use of Extension is associated with higher levels of knowledge and greater adoption rates. The new evaluation methodology can be used for assessing broad-scale impacts across Extension program areas.

Published: June 2023

To assist Extension professionals working in Texas's Little River Watershed with efforts to educate landowners about reducing amounts of bacteria there, we assessed motivations for and barriers to landowners' adopting best management practices (BMPs). We surveyed 275 landowners in the watershed. Respondents were at least somewhat familiar with nine of 11 identified BMPs. Additionally, they agreed that 10 of 13 listed factors were motivators for adopting BMPs and that six of 14 listed factors were barriers to adopting BMPs. Extension professionals can help landowners move through the innovation-decision process by targeting educational programming and materials to motivations for and barriers to adoption of such practices.

Published: June 2023

Objectives. The aim of this study was to evaluate histological effects of a new combination folkloric medicinal plant extract on bone healing in premaxillary suture expansion in rats.

Materials and methods. Thirty male Sprague–Dawley rats were used in this study. Rats were evenly divided into three groups (one control and two experimental groups) of ten each. The animals were subjected to premaxillary suture expansion by helix springs. The only expansion group is defined as the control group (Group A). The experimental groups are defined as OstokinPlus-10 (Group B) and OstokinPlus-20 (Group C). In the experimental groups, 10 and 20 ml/kg OstokinPlus herbals were applied systemically after the expansion by use of an orogastric tube during the time of study. The springs were placed and activated to deliver a 30 cN force. After 5 days, the springs were removed and replaced with short lengths of rectangular retaining wire. Tooth separation was maintained for 15 days. After a consolidation period of 15 days, the animals were euthanatized and the maxillary bone containing the midpalatal suture cartilage was surgically removed. The specimens were prepared for histomorphometric assessment of the regenerated bone.

Results. The midpalatal suture was successfully distracted following application of the activated helix spring. The distracted premaxillary suture was filled with new bone formation and unorganized fibrous tissues. Newly formed bone percentage and the bone area were found to have significant differences (p< 0.05). For investigated parameters, Group B and Group C revealed more positive results than Group A.

Conclusion: OstokinPlus herbal had positive effects on bone healing and formation during premaxillary suture expansion

Authors: Li Xiaoman , Xu Xingyu , Zhou He , Gu Yunjiao , Liu Fenghua , Wu Weiping
Published: June 2023

Broadband metamaterial-based perfect absorbers (MPAs) have significant potential in many applications. However, the design and fabrication of ultra-broadband terahertz MPAs pose considerable challenges. Most terahertz MPAs reported rely on complex, multilayer, or three-dimensional structures that are difficult to fabricate and hard to meet the miniaturization and integration requirements. In this study, we propose and investigate a novel tunable, ultra-broadband terahertz MPA of atomically thin monolayer graphene and hierarchically structured plasmonic metamaterials. The metamaterial MPA consists of alternating T-shaped gold bars, a dielectric layer, and a graphene layer on the bottom gold layer. These near-perfect absorbers exhibit an exceptional absorption of nearly 90% over an ultra-broad frequency range from 20.8 to 39.7 THz; the bandwidth is as high as 18.9 THz. Furthermore, a quantitative analysis of the impact of geometrical parameters on the absorption spectra is conducted. Additionally, the modulation of the absorption window by tuning the Fermi level of graphene is investigated, and the potential applications are discussed.
Optimal Multi-impulse Linear Rendezvous via Reinforcement Learning
Authors: Xu Longwei , Zhang Gang , Qiu Shi , Cao Xibin
Published: June 2023

A reinforcement learning-based approach is proposed to design the multi-impulse rendezvous trajectories in linear relative motions. For the relative motion in elliptical orbits, the relative state propagation is obtained directly from the state transition matrix. This rendezvous problem is constructed as a Markov decision process that reflects the fuel consumption, the transfer time, the relative state, and the dynamical model. An actor–critic algorithm is used to train policy for generating rendezvous maneuvers. The results of the numerical optimization (e.g., differential evolution) are adopted as the expert data set to accelerate the training process. By deploying a policy network, the multi-impulse rendezvous trajectories can be obtained on board. Moreover, the proposed approach is also applied to generate a feasible solution for many impulses (e.g., 20 impulses), which can be used as an initial value for further optimization. The numerical examples with random initial states show that the proposed method is much faster and has slightly worse performance indexes when compared with the evolutionary algorithm.

Collective oscillations is typical phenomena observed in the systems biology including neurons. Investigating the mechanisms for which it occurs in neural networks evokes a significant interest among neuroscientists. From mathematical point of view, the coupling schemes rule the neuron’s behaviours ranging from microscopic to macroscopic scales. This paper aims to study the impacts of coupling schemes in a minimal network of two fully coupled identical oscillators (e.g., neurons). We proceed with the research by employing the numerical approach and time-series analysis. We consider both Kuramoto-like oscillator and Leaky integrate-and-fire neuron as the objects of study. In the former case, we found the phase of two oscillators are perfectly locked and stable if their frequency are identical, as stated by the main theorem. In the latter case, the membrane potentials of two neurons are perfectly synchronized, characterized by the same firing rate, due to the effect of excitatory delta pulses.

AlN with a large bandgap energy is one of the most attractive materials for high-temperature applications. However, performance of AlN devices at high temperatures has been limited by technical problems with electrical characterization systems. Here, we show that Schottky-barrier diodes (SBDs) and metal-semiconductor field-effect transistors with Si-implanted AlN channels can operate at 1100 K and 1000 K, respectively. The breakdown voltage and barrier height of the AlN SBD were 610 V and 3.5 eV, respectively. We found that the high barrier height and thermal stability of the Ni contact on AlN greatly contributed to high-temperature operation of the devices.

A Insuficiência renal crônica (IRC) é caracterizada pelo declínio progressivo e irreversível da função renal, com uma diminuição da taxa de filtração glomerular dos rins, impedindo a manutenção da hemostasia interna do organismo, o que pode levar a necessidade de diálise, ou ao transplante renal. O objetivo deste estudo é relatar os achados bucais e o manejo no atendimento odontológico de uma paciente pediátrica com IRC. Paciente K.A.L.B, sexo feminino, 14 anos, compareceu à Policlínica Odontológica da Universidade do Estado do Amazonas, para consulta de rotina. Na anamnese, informou realizar hemodiálise três vezes na semana, haver alterações salivares (xerostomia) e recorrentes estomatites urêmicas na mucosa oral; em exames de rotina, os valores de ureia, antes da realização da hemodiálise, estavam alterados. No exame físico, observou-se palidez, devido ao quadro de anemia estabelecido. No exame clínico intraoral, verificou-se palidez da mucosa oral, presença de acúmulo de biofilme e cálculo dentário nas regiões de molares inferiores. O tratamento realizado foi raspagem sub e supragengival, profilaxia, aplicação tópica de flúor e orientações de higiene bucal. Os principais achados neste caso nos conduziram à conclusão de que pacientes com IRC podem apresentar alterações bucais que apontam o agravamento do seu quadro clínico. Além disso, para o correto manejo do tratamento odontológico desses pacientes, o cirurgião-dentista deve estar apto a reconhecer tais manifestações e, assim, dar as devidas orientações, em um âmbito interdisciplinar.

Mental health issues among college students are a growing concern, with estimates of prevalence varying widely depending on the population studied and the criteria used to define mental health issues. In this study, we aimed to explore the relationship between mental health, academic performance, and self-social mental health recovery among college students. A cross-sectional survey was conducted among college students, and data were collected on mental health, academic performance, and self-social mental health recovery. Descriptive statistics, correlation analysis, multiple regression analysis, and ANOVA were used to analyse the data. The results showed that college students reported above- average levels of mental health and academic performance, with prevalence and severity of mental health issues and factors contributing to poor mental health also rated high. The study found a significant positive relationship between factors contributing to poor mental health and self-social mental health recovery, as well as between mental health and academic performance and self-social mental health recovery. However, no significant relationship was found between prevalence and severity of mental health issues and self-social mental health recovery. The findings suggest that addressing factors contributing to poor mental health and promoting mental health and academic performance may be key in improving self-social mental health recovery among college students. Future research is needed to explore these relationships further and to identify effective strategies for promoting mental health and well-being among college students.

As the significance of employee welfare continues to grow in the management field and literature, researchers and practitioners are obliged to pay more attention to hearing and incorporating employee voice. With a focus on SK innovation in South Korea, this study examines the process by which management hears and accepts employee voice. The ‘Workplace Innovation’ project, which has been promoted by the government for more than two decades, aims to improve organizational performance and the quality of work life by fostering the collaboration of labor and management. In practice, however, the project was primarily driven by managerial decisions in the form of system introduction, organizational restructuring, and practice innovation, subsequently losing its original intent and showing limited impact. Regarding employee welfare, the necessity and urgency of each employee vary depending on individual needs and preferences, limiting the effectiveness of collective interests adjustment by a labor union. Therefore, the purpose of this study is to identify the process in which a company collects various demands from the field, individual workers make suggestions for each agenda, and the suggestions and demands of individual workers are converged to establish priorities. This case intends to contribute to establishing a foundation for further enhancing the participation of individual workers and labor unions in the process of achieving and continuing Workplace Innovation. Using the “voice-exit theory” as a framework, the process by which individual employees actively voice their thoughts and opinions are combined is classified into four types in this study. For theoretical and practical validation through a case study, this study provides an example of enhancing employee benefits and welfare at SK Innovation's Ulsan plant and describes in detail how members' opinions are collected and implemented into actual policies, focusing on the Happiness Council operation. Through the implementation of a system that facilitates regular and direct communication between members, labor, and management, the SK Innovation Happiness Council is an example of empowering employees and increasing their awareness of participation in the sense that individual members participate directly in decision-making. The present case has significant implications for Korean enterprises as it facilitates the involvement of employees and labor unions in the workplace innovation processes and enables them to establish a self-enhancing workplace innovation environment through consistent communication between labor and management.
