Effect of Psychological Meaningfulness on Job Involvement, Proactive Behavior, and Performance: Focusing on the Mediating Effect of Self-Efficacy
Authors: Kim Jeong-Sik
Published: June 2023

Employee well-being and productivity are crucial factors for organizational success, and understanding the relationships between psychological meaningfulness, job involvement, proactive behavior, and performance can help organizations to create more supportive and engaging work environments. This empirical study aimed to examine these relationships, with a particular focus on the mediating role of self-efficacy. Research models and hypotheses were derived from a literature review and tested using structural equation analysis on data collected from a questionnaire survey of 398 employees. Results indicated that psychological meaningfulness was significantly related to self-efficacy, job involvement, proactive behavior, and performance. Self-efficacy was found to play a significant mediating role in the relationship between psychological meaningfulness and job involvement, between psychological meaningfulness and proactive behavior, and between psychological meaningfulness and performance. These findings suggest that fostering employees’ psychological meaningfulness can improve their self-efficacy, job involvement, proactive behavior, and, ultimately, their performance. These results have important implications for organizations seeking to enhance their employees’ well-being and productivity.

Authors: Wang Dingran , Dai Rengqi , Luo Zihan , Wang Yuhui
Published: June 2023

Urban built-up areas confront significant environmental challenges and growing demand for enhanced residents’ well-being. Prioritizing urban green infrastructure (UGI) interventions is crucial for sustainable urban renewal. We propose a six-step framework that integrates urgency, synergy, feasibility, and typology to identify UGI intervention priorities. The framework targets detailed planning units (DPUs) and was applied to Xi’an, China. First, we assess the risks of supply–demand mismatches related to four key urban ecosystem services (UESs), namely air purification, temperature regulation, runoff regulation, and recreation. K-means clustering analysis is utilized to classify the risk typology. Next, we use the dynamic weighting method to diagnose the urgency of comprehensive risk, then evaluate the potential for synergy optimization between DPUs using local univariate and bivariate spatial autocorrelation analysis. The proportion of urban renewal land area in DPUs is employed as an indicator to evaluate the feasibility of the method. Lastly, we adopt the TOPSIS method to identify the priority ranking. Our research reveals that 51.7% of DPUs in Xi’an are at high risk of multiple supply–demand mismatches for UESs and that seven risk types need targeted optimization strategies. The DPUs ranked in the top 30 can be selected as priority UGI intervention units based on urgency, synergy, and feasibility. This study provides a scientific basis for decision making on UGI interventions in sustainable urban renewal.

Published: June 2023

This review paper explores the potential of bioleaching as a sustainable alternative for recovering metals from solid matrices. With over 12 billion tons of solid waste annually worldwide, bioleaching provides a promising opportunity to extract metals from solid waste, avoiding harmful chemical processes. It explains bacterial and fungal bioleaching techniques that extract copper, gold, zinc, and other metals from solid matrices. Fungal bioleaching effectively extracts a wide range of valuable metals, including nickel, vanadium, aluminium, molybdenum, cobalt, iron, manganese, silver, platinum, and palladium. The review highlights different solid matrices with metal contents that have the potential to be recovered by bioleaching, presenting promising bioprocess alternatives to current industrially available technologies for metal recovery. The optimal conditions for bioleaching, including pH, temperature, agitation–aeration, and pulp density are also discussed. The review shows that bioleaching has the potential to play a crucial role in the transition to a more sustainable and circular economy by providing an efficient, cost-effective, and environmentally friendly method for metal recovery from solid matrices.

Authors: Amezquita Lucio , Castillo Oscar , Soria Jose , Cortes-Antonio Prometeo
Published: June 2023

In this work, we present multiple variations of the Multi-verse Optimizer Algorithm (MVO) using chaotic maps, using it in the formation of new solutions. In these new variations of the MVO algorithm, which we call the Fuzzy-Chaotic Multi-verse Optimizer (FCMVO), we use multiple chaotic maps used in the literature to substitute some of the parameters for which the original algorithm used a random value in the formation of new universes or solutions. To implement chaos theory on these new variants, we also use Fuzzy Logic for dynamic parameter adaptation; the first tests are performed only using chaotic maps, and then we merge the use of Fuzzy Logic in each of these cases to analyze the improvement over the Fuzzy MVO. Subsequently, we use only the best-performing chaos maps in a new set of variants for the same cases; after these results, we observe the behavior of the algorithm in different cases. The objective of this study is to compare whether there is a significant improvement over the MVO algorithm using some of the best-performing chaotic maps in conjunction with Fuzzy Logic in benchmark mathematical functions prior to moving on to other case studies.

Authors: Chen Ye , Shen Lei , Bian Yuchen , Zhang Xi
Published: June 2023

Over the past two decades, there has been a surge in digital innovation. China is the world’s second-largest digital economy entity and the national strategy to build a digital China is in full swing. Chinese enterprises have received great support while pursuing digital transformation. This study aims to explore the impact of digital transformation on firm dynamic capital structure adjustment by taking evidence from Chinese listed firms. Based on the data of 3855 Chinese A-share listed firm-year observations during 2011–2021, this study employed a panel data fixed effects model to ascertain the association between the proposed variables. The results indicate that digital transformation has a significant positive effect on accelerating capital structure adjustment speed. Furthermore, we show that digital transformation promotes dynamic capital structure adjustment through financial flexibility. The impact of digital transformation on dynamic capital structure adjustment is characterized by heterogeneity in the ownership type, asset size, and credit cycle. In addition, reduced financing constraints and growing economic policy uncertainty will moderate the relationship between digital transformation and dynamic capital structure adjustment. Our findings provide insights into how digital transformation is driving companies to accelerate their capital structure adjustment speed to the optimal, and supplements the existing literature on the determinants of dynamic capital structure adjustment.

Authors: Labaška Miroslav , Gál Miroslav , Mackuľak Tomáš
Published: June 2023

Chemical warfare agents (CWAs) are one of the most toxic compounds. Degradation of CWAs using decontamination agents is one of the few ways to protect human health against the harmful effects of CWAs. A ferrate (VI)-based potential chemical warfare agent decontaminant was studied for the degradation of persistent nitrogen mustard (tris(2-chloroethyl)amine, HN3). By optimizing the reaction conditions, the complete degradation of HN3 was achieved in 4 min. The degradation products contained mostly reduced Fe species, which confirmed the environmental friendliness of the proposed decontamination solution.

Published: June 2023

Peanut seeds are susceptible to Aspergillus flavus infection, which has a severe impact on the peanut industry and human health. However, the molecular mechanism underlying this defense remains poorly understood. The aim of this study was to analyze the changes in differentially expressed genes (DEGs) and differential metabolites during A. flavus infection between Zhonghua 6 and Yuanza 9102 by transcriptomic and metabolomic analysis. A total of 5768 DEGs were detected in the transcriptomic study. Further functional analysis showed that some DEGs were significantly enriched in pectinase catabolism, hydrogen peroxide decomposition and cell wall tissues of resistant varieties at the early stage of infection, while these genes were differentially enriched in the middle and late stages of infection in the nonresponsive variety Yuanza 9102. Some DEGs, such as those encoding transcription factors, disease course-related proteins, peroxidase (POD), chitinase and phenylalanine ammonialyase (PAL), were highly expressed in the infection stage. Metabolomic analysis yielded 349 differential metabolites. Resveratrol, cinnamic acid, coumaric acid, ferulic acid in phenylalanine metabolism and 13S-HPODE in the linolenic acid metabolism pathway play major and active roles in peanut resistance to A. flavus. Combined analysis of the differential metabolites and DEGs showed that they were mainly enriched in phenylpropane metabolism and the linolenic acid metabolism pathway. Transcriptomic and metabolomic analyses further confirmed that peanuts infected with A. flavus activates various defense mechanisms, and the response to A. flavus is more rapid in resistant materials. These results can be used to further elucidate the molecular mechanism of peanut resistance to A. flavus infection and provide directions for early detection of infection and for breeding peanut varieties resistant to aflatoxin contamination.

Chihuahua is the largest state in Mexico. The ecosystem of this region is composed of large area of bushes, forests, and grasslands, which allows for a specific diversity of fauna; among them are interesting species of non-lethal scorpions. Most of the Chihuahuan scorpions have been previously morphologically and molecularly described; however, this manuscript could be the first to describe the composition of those venoms. This work aimed at the collection of two scorpion species from the region of Jiménez (Southwest of the State of Chihuahua), which belong to the species Chihuahuanus cohauilae and Chihuahuanus crassimanus; the two species were taxonomically and molecularly identified using a 16S DNA marker. Reverse-phase high-performance liquid chromatography (RP-HPLC) of C. coahuilae and C. crassimanus venoms allowed the identification of three fractions lethal to mice. Additionally, three fractions of each scorpion displayed an effect on house crickets. In the end, three new fractions from the venom of C. coahuilae were positive for antimicrobial activity, although none from C. crassimanus venom displayed growth inhibition. Despite being a preliminary study, the venom biochemical analysis of these two uncharacterized scorpion species opens the opportunity to find new molecules with potential applications in the biomedical and biotechnological fields.

Effective control of diseases transmitted by Aedes aegypti is primarily achieved through vector control by chemical insecticides. However, the emergence of insecticide resistance in A. aegypti undermines current control efforts. Arachnid venoms are rich in toxins with activity against dipteran insects and we therefore employed a panel of 41 spider and 9 scorpion venoms to screen for mosquitocidal toxins. Using an assay-guided fractionation approach, we isolated two peptides from the venom of the tarantula Lasiodora klugi with activity against adult A. aegypti. The isolated peptides were named U-TRTX-Lk1a and U-TRTX-Lk2a and comprised 41 and 49 residues with monoisotopic masses of 4687.02 Da and 5718.88 Da, respectively. U-TRTX-Lk1a exhibited an LD50 of 38.3 pmol/g when injected into A. aegypti and its modeled structure conformed to the inhibitor cystine knot motif. U-TRTX-Lk2a has an LD50 of 45.4 pmol/g against adult A. aegypti and its predicted structure conforms to the disulfide-directed β-hairpin motif. These spider-venom peptides represent potential leads for the development of novel control agents for A. aegypti.
Cytotoxic T Lymphocytes Control Growth of B16 Tumor Cells in Collagen–Fibrin Gels by Cytolytic and Non-Lytic Mechanisms
Authors: Majumder Barun , Budhu Sadna , Ganusov Vitaly V.
Published: June 2023

Cytotoxic T lymphocytes (CTLs) are important in controlling some viral infections, and therapies involving the transfer of large numbers of cancer-specific CTLs have been successfully used to treat several types of cancers in humans. While the molecular mechanisms of how CTLs kill their targets are relatively well understood, we still lack a solid quantitative understanding of the kinetics and efficiency by which CTLs kill their targets in vivo. Collagen–fibrin-gel-based assays provide a tissue-like environment for the migration of CTLs, making them an attractive system to study T cell cytotoxicity in in vivo-like conditions. Budhu.et al. systematically varied the number of peptide (SIINFEKL)-pulsed B16 melanoma cells and SIINFEKL-specific CTLs (OT-1) and measured the remaining targets at different times after target and CTL co-inoculation into collagen–fibrin gels. The authors proposed that their data were consistent with a simple model in which tumors grow exponentially and are killed by CTLs at a per capita rate proportional to the CTL density in the gel. By fitting several alternative mathematical models to these data, we found that this simple “exponential-growth-mass-action-killing” model did not precisely describe the data. However, determining the best-fit model proved difficult because the best-performing model was dependent on the specific dataset chosen for the analysis. When considering all data that include biologically realistic CTL concentrations (E≤107cell/mL), the model in which tumors grow exponentially and CTLs suppress tumor’s growth non-lytically and kill tumors according to the mass–action law (SiGMA model) fit the data with the best quality. A novel power analysis suggested that longer experiments (∼3–4 days) with four measurements of B16 tumor cell concentrations for a range of CTL concentrations would best allow discriminating between alternative models. Taken together, our results suggested that the interactions between tumors and CTLs in collagen–fibrin gels are more complex than a simple exponential-growth-mass–action killing model and provide support for the hypothesis that CTLs’ impact on tumors may go beyond direct cytotoxicity.

Published: June 2023

Foot-and-mouth disease (FMD) is a highly infectious disease affecting cloven-hoofed animals and causes significant economic losses to the livestock industry. The Type O PanAsia-2 (O PA-2) vaccine strain is protective against a wide range of serotype O FMD virus (FMDV) strains in East Asia, and A22 Iraq/24/64 (A22 IRQ) is the most widely used vaccine strain in FMD vaccine antigen banks. The aim of this study was to produce antigens from O PA-2 and A22 IRQ viruses using a 100 L bioreactor and evaluate the protective efficacy of varying antigen concentrations in pigs. More than 2 μg/mL of the antigen was recovered from the O PA-2 and A22 IRQ virus-infected supernatants. Further, inactivation of O PA-2 and A22 IRQ by binary ethyleneimine revealed that the viral titers decreased below 10−7 TCID50/mL within 13 h and 9 h, respectively. The O PA-2 and A22 IRQ vaccines, containing 10 μg and 5 μg of antigen, respectively, provided protection against homologous viruses in pigs. This is the first report demonstrating that the antigens obtained from the pilot-scale production of O PA-2 and A22 IRQ are viable candidate vaccines. These results will pave the way for industrial-scale FMD vaccine production in South Korea.
Recovery of Routine Immunisation: Mapping External Financing Opportunities for Reaching Zero-Dose Children
Authors: Tougher Sarah , Mandalia Nikhil , Kou Griffiths Ulla
Published: June 2023

The COVID-19 pandemic has precipitated large declines in childhood vaccination coverage and, consequently, substantial increases in the number of zero-dose children. To effectively respond to these declines, it is necessary to direct resources for recovery. We mapped active external financing for immunisation and primary healthcare in 20 countries with the highest numbers of zero-dose children to promote transparency and donor coordination. We found that countries have disparate access to external financing, with the two upper-middle-income countries (Brazil and Mexico) only having access to loans from the International Bank for Reconstruction and Development. Domestic resource mobilization is, therefore, key in these two countries, although fiscal space is likely constrained. Four additional countries (Angola, Indonesia, Philippines, and Vietnam) do not have allocations from Gavi, the Vaccine Alliance for Health Systems Strengthening, or Equity Accelerator Funding, but are eligible for support under Gavi’s Middle-Income Countries Approach. Our methods, which focus on current donor financing, are novel and reveal substantial variations in access to external financing to support immunisation in high-burden countries. The available data differ considerably across financing mechanisms, making it difficult to synthesise the results across funding sources.
Expression of E. coli FimH Enhances Trafficking of an Orally Delivered Lactobacillus acidophilus Vaccine to Immune Inductive Sites via Antigen-Presenting Cells
Authors: Vilander Allison C. , Shelton Kimberly , LaVoy Alora , Dean Gregg A.
Published: June 2023

The development of lactic acid bacteria as mucosal vaccine vectors requires the identification of robust mucosal adjuvants to increase vaccine effectiveness. The E. coli type I fimbriae adhesion protein FimH is of interest as a mucosal adjuvant as it targets microfold (M) cells enhancing vaccine uptake into Peyer’s patches and can activate the innate immune system via Toll-like receptor (TLR) 4 binding. Here, we displayed the N-terminal domain of FimH on the surface of a Lactobacillus acidophilus vaccine vector and evaluated its ability to increase uptake of L. acidophilus into Peyer’s patches and activate innate immune responses. FimH was robustly displayed on the L. acidophilus surface but did not increase uptake into the Peyer’s patches. FimH did increase trafficking of L. acidophilus to mesenteric lymph nodes by antigen-presenting cells including macrophages and dendritic cells. It also increased transcription of retinaldehyde dehydrogenase and decreased transcription of IL-21 in the Peyer’s patches and mesenteric lymph nodes. The N-terminal domain of FimH did not activate TLR4 in vitro, indicating that FimH may stimulate innate immune responses through a not-yet-identified mechanism. These results indicate that E. coli FimH alters the innate immune response to L. acidophilus and should be further studied as an adjuvant for lactic acid bacterial vaccine platforms.

Published: June 2023

(1) Background: Here, we investigate the incidence of mpox and factors associated with vaccine uptake in mainly well-treated men who have sex with men and are living with HIV (MSMWH). (2) Methods: This study included 727 MSMWH from the Copenhagen co-morbidity in HIV infection (COCOMO) study from 1 May to 31 October 2022. Mpox infection and vaccination status were obtained from the Danish Microbiology Database and The Danish Vaccination Register. Vaccination willingness was assessed through an online survey. (3) Results: At a median follow-up of 180 days, 13 (1.8%) participants had laboratory-confirmed mpox infections. Furthermore, 238 (32.7%) had received the mpox vaccine. A sexually transmitted disease (STD) in the preceding two years was associated with a higher risk of mpox infection (hazard ratio 7.1; 95% confidence interval (CI) [1.9–26.9]) and with higher odds of vaccination (adjusted odds ratio 3.1; 95% CI [2.2–4.6]). 401 (55.2%) participants responded to the survey. 228 (57.0%) reported very high vaccination willingness. The self-perceived risk of infection was associated with vaccine uptake. (4) Conclusions: The incidence of mpox was low. A prior STD was associated with both a higher risk of mpox infection and higher odds of vaccination. Despite high-risk sexual behavior and high vaccination willingness, a sizable fraction of participants had not been vaccinated.
The Indirect Antiglobulin (Coombs’) Test Is Specific but Less Sensitive Than the Direct Antiglobulin Test for Detecting Anti-Erythrocytic Autoantibodies and Thereby Immune-Mediated Hemolytic Anemia in Dogs
Authors: Idalan Nadine , Müller Elisabeth , Giger Urs
Published: June 2023

The immunodiagnostic assessment of dogs suspected of having immune-mediated hemolytic anemia (IMHA) is based on persistent autoagglutination of erythrocytes (after three saline washes), marked spherocytosis, and a positive direct antiglobulin (Coombs’) test (DAT). However, the value of using the indirect antiglobulin test (IAT) for the detection of anti-erythrocytic autoantibodies in serum from dogs suspected of having IMHA is unclear. To evaluate the IAT, leftover serum samples from a large cohort of 94 dogs suspected of having IMHA and for which DAT results were known were incubated with DAT− erythrocytes, and five IAT techniques were performed (in part with different reagents and temperatures): microtiter plate (MICRO), microcapillary, laboratory gel column, gel minitube kit (GEL KIT), and immunochromatographic strip kit. Two IAT techniques (MICRO at 37 °C and GEL KIT with rabbit anti-dog polyvalent reagent) detected autoantibodies against erythrocytes in serum from 53% and 57% of DAT+ dogs, respectively, while other IATs performed less well. Moreover, while the analytic specificity of the IAT methods compared to the DAT ranged from 96–100%, the sensitivity range was only 9–57%. Thus, we still recommend DAT for diagnosis and monitoring of IMHA in dogs but conclude that a positive IAT result may aid diagnostically when serum is available, but fresh red blood cells are not.
The Importance of Assessing Water Quality in Tributaries: A Case Study in an Urban Waterway Using Zebrafish (Danio rerio)
Authors: Malik Sabine , Cohen Annastelle , MacAvoy Stephen E. , Connaughton Victoria P.
Published: June 2023

Tributaries are important for fish recruitment and diversity. Here, we examine the biological impact of inorganic and organic contaminants in Paint Branch stream (PBS), a tributary of the Anacostia river in Washington D.C. The Anacostia has suffered severe ecological damage because of decades of pollution and deposited wastewater runoff; however, PBS, which connects to the northern part of the river, is forested and less urbanized, suggesting higher water quality. However, the impact of PBS water on early fish development has not been studied. To address this question, we examined if chronic (28 day) exposure to water collected from PBS can support the proper early development of zebrafish (Danio rerio), a vertebrate model in toxicological studies. We assessed their overall growth and swimming behaviors and correlated these results with a water quality analysis. The water chemistry identified high levels of calcium, sodium, and nitrate in PBS water samples. A gas chromatography–mass spectroscopy analysis of extracted non-polar compounds in the water column revealed siloxanes (congeners D6–D10) were the only component identified with >90% certainty. In our fish experiments, we observed age-dependent increases in growth and eye development, consistent with normal development. In contrast, general swimming behaviors showed an early increase in angular velocity at 7 days postfertilization (dpf; p = 0.001) and a decreased total distance traveled at 14 dpf (p = 0.015) for PBS-treated larvae. Using the open field test, we observed that the PBS-treated fish made fewer visits to the edge at 7 (p = 0.01), 14 (p < 0.001), and 21 dpf (p = 0.038) and spent significantly more time at the edge at 21 dpf (p < 0.001). Fewer visits to the center were also noted at 14 and 21 dpf, suggesting reduced overall movement at these two ages in response to chronic PBS water exposure. Interestingly, by 28 dpf, no differences were noted in any parameter measured. Overall, these results indicate zebrafish larvae grew well in PBS water; however, their reduced movement and anxiogenic behavior suggested subtle behavioral abnormalities. The identified chemicals likely originated from runoff or sewage and have potentially deleterious consequences for fish living in PBS or migrating to/from upstream spawning/nursery locations.

Published: June 2023

The sepiolite/ZrO2 composites were prepared by sepiolite (Sep) modification with zirconium propoxide in toluene at room temperature for 24 h (Sep–ZrI) or 95 °C for 4 h (sample Sep–ZrII). The efficiency of the obtained composites for the removal of phosphate from aqueous solutions at initial pH = 4 and pH = 8 was investigated. Characterization of the samples shows that synthesis at a higher temperature for a shorter time provides a slightly higher content of amorphous Zr phase, which is deposited on the sepiolite fibers as a thin layer and agglomerated nanoparticles. Compared to Sep, the composites have a lower point of zero charge and higher specific surface area and pore volume. The adsorption kinetics follow the pseudo second-order model. The adsorption capacities of the composites are approximately the same at both initial pH and higher at initial pH = 4 than at pH = 8. The XPS and ATR-FTIR of Sep–ZrI before and after adsorption identifies the formation of inner-sphere complexes as the mechanism of phosphate adsorption. The slow release during desorption with NaOH solution confirms the strong bonds of the phosphates with the surface of the composites.

Published: June 2023

Not so long ago one of the main and traditional problems of Russia has been that culture was not considered to be a subject of political life. Before the bill "About Culture” each region in the country used to live in different cultural context and to understand aspects of culture in different manners. At the edges of 20th–21st cc. the understanding of the problems of Russia-Caucasian social and cultural communication actualized. North Caucasian region is a complicated system of very many cultures. It was a contact zone and at the same time a kind of a barrier among civilizations and empires in The Mediteranian region, South-Western Asia and Eastern Europe. The today culture of North Caucasian region has been formed as a result of the dialogue among Caucasian mountain, Islam and Russian civilizations and cultures, and also the processes of modernization during 20th-21-st centuries. The problem of preserving of cultural traditions is a central one in "ases of state culturally politics" (2014). Cultural bridges among the peoples and countries should be kept even in times of war conflicts and military actions.
July 8, 2020 — World Allergy Day
Authors:   RSAHI Tomsk Regional Clinical Hospital, Tomsk, Guseva G. R.
Published: June 2023

The decision to mark World Allergy Day was made in 2005 at the initiative of the World Allergy Organization. The purpose of the holiday is to inform the general population about the symptoms of allergic manifestations and promote regular examinations and checkups. A third of the adult population of the Russian Federation and a quarter of children and adolescents periodically suffer from manifestations caused by allergies. This disease is an immunopathological reaction of the body to the effects of any agent as a result of the development of sensitization to it. Currently, there is a trend towards a steady increase in the manifestations of allergic reactions, which scientists attribute to the increasing daily use of various preservation agents, chemicals, dyes, new drugs, and cosmetics. The main symptoms and manifestations of allergies include a runny nose, redness of the eyes, watery eyes, wheezing, bronchospasm, shortness of breath, various skin rashes, and sometimes a headache. One of the most dangerous manifestations of allergy is anaphylactic shock, which manifests itself in the form of itching, pronounced respiratory failure, excessive sweating, thready pulse, and a drop in blood pressure. If medical assistance is not provided in time, such a condition can be fatal.
Neoliberal narrative about competition and equality of chances
Authors:   Department of practical psychology, Omsk state pedagogical University, Il'in A.N.
Published: June 2023

The article criticizes the position of neoliberal ideology, according to which every person in a market society has an equal chance of success. Various factors neutralizing the validity of this thesis are considered. Depending on the economic, social and cultural capital of the family, a person has chances for vertical mobility. The thesis of equality of chances seems to be a mythologeme, specially constructed and replicated for political purposes. It is proved that inequality is an integral aspect of the neoliberal order. We are talking about inequality both at the microsocial level and at the international level. Free competition is presented as an unattainable ideal.

The Covid-19 pandemic has harmed freshwater fish cultivators, mainly gourami. Cultivators complained and were threatened with bankruptcy because not only have the selling price been low since the start of the pandemic, but the price of feed has also continued to rise. The situation encouraged gourami cultivators to switch to other types of cultured fish, like catfish and ornamental fish such as koi. The Community Service Team initiated to offer a solution in increasing the added value of gourami through processing it into nutritious fishball. The main result of this activity was to increase the added value of the product to increase selling value, product quality, industrial productivity, employment, income, and the welfare of gourami cultivators and their families. The activity was carried out by applying a participatory approach model and training in processing and producing gourami fishball for several groups of cultivators in several villages in Kalidawir District, Tulungagung.

This service activity aims to improve the capability of local tour guides in buffer villages in the Bromo Tengger Semeru National Park (TNBTS) area. One of the locations chosen by the Service team is Wonokitri Village, which is located close to the tourist destination of Mount Bromo. Based on the results of field observations, there are several problems why Wonokitri Village is only able to survive as a 'transit village' which is indicated by the low occupancy of tourists staying at local guest houses. This is due to the low communication skills of local tour guides to attract both domestic and foreign tourists to stay longer in Wonokitri Village. In fact, based on the narrative of local residents, they are trying to develop other tourist objects that are expected to be able to support the local economy. Through this service activity, the Proposing Team arranged a series of mentoring and training activities for members of the Tourism Awareness Group (Pokdarwis) in Wonokitri Village, Tosari District, Pasuruan Regency. The service activities consist of first, training in communication skills for tour guides and tourism actors (owners of guest houses, stalls, and souvenir sellers). Second, assistance in making social media as a promotional media, branding as well as local tourism marketing. Finally, thirdly, English language skills training in the context of tourism for tour guides and other tourism actors. The outputs of this activity are publications in the mass media, activity documentation, scientific articles presented at national seminars, and scientific articles published in accredited national journals.

Hal ini disebabkan oleh beberapa aplikasi yang didownload dan terpasang di handphone para milenial, dimana kurangnya awareness-nya dengan tidak menghiraukan aturan kesepakatan dalam permulaan instalasi setiap aplikasi atau kadang kurangnya pemahaman aturan kesepakatan aplikasi yang sering disediakan dalam bahasa inggris. Bahkan tidak sedikit, mahasiswa yang tidak sengaja terjebak dalam pinjaman online dengan menyerahkan data pribadi dan informasi personal lainnya dalam mengakses data didalam handphonenya.
