Published: March 2022

Purpose: To investigate the effect of apatinib combined with chemotherapy on quality of life (QOL) and related complications in patients with advanced gastric cancer (AGC).

Methods: Clinical data for 102 AGC patients treated in The Affiliated Hospital of Hebei University (January 2018 - December 2019) were retrospectively analyzed. The subjects were randomly and equally split into chemotherapy group and combination group. Both groups of patients were treated with 180 mg/m2 of paclitacel, and patients in the combination group were additionally given 500 mg of apatinib daily, for a treatment time to disease remission in both groups. Clinical efficacy, QOL, complications as well as serum SIL-2R, VEGF and TNF-α levels in the two groups were compared to analyze the effect of apatinib combined with chemotherapy on AGC patients.

Results: Disease control rate (DCR) and overall response rate (ORR) of gastric cancer patients in the combination group were notably higher than those in the chemotherapy group (p < 0.05). After treatment, the serum SIL-2R, VEGF and TNF-α levels in the two groups decreased significantly, of which the levels in the combination group were clearly lower (p < 0.05). No notable difference in the incidence of complications was observed between the two groups (p > 0.05). After treatment, the QOL scores of both groups increased significantly, of which QOL score in the combination group was notably higher (p < 0.05).

Conclusion: Apatinib combined with chemotherapy effectively enhances the clinical efficacy of AGC patients, controls the overexpression of serum SIL-2R, VEGF and TNF-α, and improves the QOL of patients without increasing adverse reactions. Therefore, the combination therapy is safe and effective.

Purpose: To study the clinical effectiveness of a combination of Paiteling and cryotherapy in the treatment of vulval condyloma acuminatum (VCA), and its effect on late recurrence.

Methods: Eighty-six VCA patients were chosen as research subjects, and were randomized into group A and group B. Group A patients were treated with combination of Paiteling and cryotherapy, while group B patients received cryotherapy only. The clinical effects of the two treatment methods on VCA were evaluated by measuring area of damaged skin, levels of interleukin-6 (IL-6) and C-reactive protein (CRP), as well as degree of recurrence of VCA in the two groups, before and after treatment.

Results: Total clinical treatment effectiveness in group A was significantly higher compared with group B (p < 0.05). After treatment, the area of damaged skin, and levels of IL-6 and CRP were markedly lower in group A than in group B (p < 0.001). After 6 months of treatment, disease control was higher in group A than in group B (p < 0.05). There was also a lower incidence of adverse reactions in group A than in group B (p < 0.05).

Conclusion: These results indicate that the combination of Paiteling and cryotherapy is more effective than cryotherapy alone in improving treatment effectiveness and reducing late recurrence of VCA. Therefore, the combined treatment has potentials clinical application in the management of VCA.
A damage criterion based on energy balance for isotropic cohesive zone model
Authors: Chrysochoos André , Daridon Loïc , Renouf Mathieu
Published: March 2022

The objective of this paper is to present an energy damage criterion for cohesive zone models (CZM) within the framework of the non-linear thermodynamics of irreversible processes (TIP). An isotropic elastic damageable material is considered for isothermal transformations. Damage is then the only irreversible effect accompanying the deformation process and this mechanism is supposed to be fully dissipative. Once a separation law and a damage state variable have been chosen, the paper shows that the damage criterion can be automatically derived from the energy balance. From this observation, a CZM is derived for a given choice of traction-separation law and damage state variable and the quality of its numerical predictions is analyzed using an experimental benchmark bending test extracted from literature. Finally, damage, elastic and dissipated energy fields around the crack path are shown during this rupture test.
The Big-O Problem
Authors: Chistikov Dmitry , Kiefer Stefan , Murawski Andrzej S. , Purser David
Published: March 2022

Given two weighted automata, we consider the problem of whether one is big-O
of the other, i.e., if the weight of every finite word in the first is not
greater than some constant multiple of the weight in the second.
We show that the problem is undecidable, even for the instantiation of
weighted automata as labelled Markov chains. Moreover, even when it is known
that one weighted automaton is big-O of another, the problem of finding or
approximating the associated constant is also undecidable.
Our positive results show that the big-O problem is polynomial-time solvable
for unambiguous automata, coNP-complete for unlabelled weighted automata (i.e.,
when the alphabet is a single character) and decidable, subject to Schanuel's
conjecture, when the language is bounded (i.e., a subset of $w_1^*\dots w_m^*$
for some finite words $w_1,\dots,w_m$) or when the automaton has finite
ambiguity.
On labelled Markov chains, the problem can be restated as a ratio total
variation distance, which, instead of finding the maximum difference between
the probabilities of any two events, finds the maximum ratio between the
probabilities of any two events. The problem is related to
$\varepsilon$-differential privacy, for which the optimal constant of the big-O
notation is exactly $\exp(\varepsilon)$.

Published: March 2022

Se evaluaron dos genotipos altos y cuatro enanos de Yerba Elefante (Pennisetum purpureum Schum.) a tres intervalos de corte (IC) en dos localidades. Los rendimientos de materia seca (RMS) promedio de Merkerón y Merker (yerba altas) a IC de 45-, 65-, y 85-d (37.5, 48.8 y 52.8 t/ha/año, respectivamente) resultaron significativamente mayores (P = 0.05) que los de las yerbas enanas. El RMS promedio de las yerbas aumentó 15% (P = 0.05) de 45- a 65-d. La concentración de proteína cruda promedio de N75 y N127 (enanas) a IC de 45-y 65-d superó (P = 0.05) a las yerbas altas y a las restantes yerbas enanas. En muchos casos los rendimientos de proteína cruda de Merkerón y Merker excedieron (P = 0.05) los de las yerbas enanas. La altura de planta de Merkerón y Merker fueron superiores (P = 0.05) durante los tres IC. Las yerbas N75 (IC de 45-d) y N75 y N128 (IC de 65- y 85-d) registraron ios valores más altos (P = 0.05) de razón hoja:talio. No hubo diferencias significativas entre los seis Pennisetums en términos de digestibilidad aparente in vitro. Los resultados sugieren que las yerbas Merkerón y Merker pueden ser recomendadas para uso bajo corte y las yerbas enanas, especialmente N75 y N128 para pastoreo.

Published: March 2022

The roundjaw bonefish, Albula glossodonta, is the most widespread albulid in the Indo-Pacific and is vulnerable to extinction. We assembled the genome of a roundjaw bonefish from Hawai‘i, USA, which will be instrumental for effective transboundary management and conservation when paired with population genomics datasets. The 1.05 gigabase pair (Gbp) contig-level assembly had a 4.75 megabase pair (Mbp) NG50 and a maximum contig length of 28.2 Mbp. Scaffolding yielded an LG50 of 20 and an NG50 of 14.49 Mbp, with the longest scaffold reaching 42.29 Mbp. The genome comprised 6.5% repetitive elements and was annotated with 28.3 K protein-coding genes. We then evaluated population genetic connectivity between six atolls in the Western Indian Ocean with 38,355 SNP loci across 66 A. glossodonta individuals. We discerned shallow population structure and observed genetic homogeneity between atolls in Seychelles and reduced gene flow between Seychelles and Mauritius. The South Equatorial Current might be the limiting mechanism of this reduced gene flow. The genome assembly will be useful for addressing taxonomic uncertainties of bonefishes globally.

Published: March 2022

Chitinases are enzymes that digest the polysaccharide polymer chitin. During insect development, breakdown of chitin is an essential step in molting of the exoskeleton. Knockdown of chitinases required for molting is lethal to insects, making chitinase genes an interesting target for RNAi-based pest control methods. The Asian citrus psyllid, Diaphorina citri, carries the bacterium causing Huanglongbing, or citrus greening disease, a devastating citrus disease. We identified and annotated 12 chitinase family genes from D. citri as part of a community effort to create high-quality gene models to aid the design of interdictory molecules for pest control. We categorized the D. citri chitinases according to an established classification scheme and re-evaluated the classification of chitinases in other hemipterans. In addition to chitinases from known groups, we identified a novel class of chitinases present in D. citri and several related hemipterans that appears to be the result of horizontal gene transfer.
Unpacking Land Degradation Neutrality (LDN), An Emerging Paradigm to Conserve Land Systems’ Sustainability in the 21st Century? Meta-analysis of Challenges and Opportunities
Authors: Kesavan A. , Kaur H. , Chaudhuri S.
Published: March 2022

The UN Sustainable Development Goals specifically note the growing importance of land degradation management and mitigation strategies, advocating for global collaboration and innovative research and policy outlook. In this reflective summary, we synthesize the current worldview (post-2000) on land degradation neutrality (LDN), an emerging concept in the field of environmental sustainability that advocates a dynamic balance between degradation and restoration, to ensure no net loss in productive land resources. We first introduce the LDN Causal Framework (theoretical framework of LDN), followed by the Logic Model – guideline for on-ground LDN method implementation (comprising preparatory activities, followed by Integrated Land Use Planning (ILUP), and LDN Response Hierarchy (Avoid-Reduce-Reverse)). We draw attention to growing concerns about LDN technical problems: restore vs. rehabilitate; selecting indicator variables, and establishing a baseline. In the final section, we reflect on the social-ecological aspect of LDN – harnessing participatory action (multi-stakeholder engagement) and gender mainstreaming. Overall, LDN presents an umbrella vision for environmental regeneration and land capital management, that requires seamless integration of natural with social sciences, the policy with law, and requires strategic community mobilization.
A ORIGEM DOS RITUAIS INICIÁTICOS COMO REFORMULAÇÃO EXISTENCIAL DA VISÃO DO HOMEM
Authors: Pinto Paulo Mendes
Published: March 2022

As grandes narrativas foram palco de uma visão pouco promissora para o Homem. A humanidade foi muitas vezes desconsiderada e posta ao serviço, sem que se pudesse evocar outro destino; pelo menos até a passagem do II para o I milénio A.E.C. Depois deste foco de experiência existencial, os rituais iniciáticos, que compunham a trama literária, permitiram uma reformulação da categoria que o homem assumiu.

“Advancing our Collective Awareness in Doing Social Justice Research”: A Book Review of Anna CohenMiller and Nettie Boivin’s Questions in Qualitative Social Justice Research in Multicultural Contexts
Authors: Romm Norma
Published: March 2022

In the book, Questions in Qualitative Social Justice Research in Multicultural Contexts, the authors, Anna CohenMiller and Nettie Boivin, ask provocative questions meant to stimulate us as qualitative researchers to strengthen options for conducting “better” research which is likely to advance inclusion and equity for communities who have been historically marginalized, colonized and/or oppressed. The book is adeptly structured so to invite us to (re)consider possible answers to their questions posed. As part of explicating the diversity of approaches to questions that can and should be asked regarding the doing of inclusive qualitative research, they include vignettes of a range of additional contributors who thoughtfully present/narrate their “reflections from the field” towards the end of each chapter. The book re-opens discussion on topics such as: owning our power (and rebalancing power relations), developing trust through building relationships, reconsidering the “insider/outsider” divide, activating transformative research, working with cross-disciplinarity in a research team, undertaking ethical online research, and credentializing different ways of “knowing,” including arts-based productions. Readers of this book should surely be inspired to consider new possibilities for practicing social justice research. The book is about social justice research and as such does not directly address ecological justice from a non-anthropocentric perspective, but some of the reflections from the field refer to caring for non-sentient beings and other “being,” thus paving a way for us to include this in our considerations when pursuing a justice agenda in the research process.

The need for information and communication has become a fundamental thing in human life, marked by the increasing human activity that no longer sees the distance and time to communicate with and share information. In 1960, the US Department of Defense conducted research on computer networks. Research carried out is to build a computer network with a method that mimics the workings of the telephone network, where one computer can be connected to other computers, both in one location or area known as a Local Area Network (LAN), and even can be connected to a place or a different country known as a Wide Area Network (WAN). LAN limitations give birth to a VLAN technology that allows for the configuration of a virtualized computer network. The higher the level of demand and the increase in computer network users resulting in broadcasts and traffic on the network itself. The current condition of PT. EDS Manufacturing Indonesia does not yet have a computer network concept that is in line with company needs, computer network activities that occur every day require concepts that are appropriate to the company. Then it is necessary to design a VLAN concept that is expected to provide better results and make it easier for IP Address segmentation to manage broadcast and traffic on a computer network.

DNA Barcoding of Red Jungle Fowls (Gallus gallus philipensis Hatchisuka) from Different Mountain Areas in the Philippines
Authors:   University of the Philippines Los Baños, Bondoc Orville
Published: March 2022

Initially proposed as a global standard for rapid species identification, DNA barcodes (cytochrome c oxidase subunit I or COI in the mitochondrial genome) were determined to assess diversity and genetic distances among 25 red jungle fowls (Gallus gallus philipensis Hatchisuka) obtained from different mountain areas in 23 provinces of 12 islands in the Philippines. Results of the evolutionary analyses using Kimura two-parameter model in MEGA5 indicated existence of two main evolutionary clades, and effectiveness of DNA barcodes in identifying and differentiatiang red jungle fowls between and within clades. Genbank-accessed COI sequences of three subspecies of red jungle fowls (Gallus gallus gallus, Gallus gallus bankiva, Gallus gallus spadiceus) and three Gallus species (G. lafayettei, G. sonneratii, G. varius) were clustered in the intermediate zone between differentiated populations of Philippine red jungle fowls, but more recently diverged with those in Clade A. Based on 627 positions from 25 COI sequences, average genetic distance among red jungle fowls was 0.254 units, demonstrating close resemblance within clade, but greater divergence between clades (d>1). Genetic divergence within Clade A (d=0.294) was higher than Clade B (d=0.215). Moreover, pooled pair-wise genetic distance was not significantly correlated (P>0.05) with geographical distances among red jungle fowls between and within clades. Evolutionary analysis of the DNA barcodes of Philippine red jungle fowls provided important information on genetic variability and population structure useful to support decisions on agrobiodiversity conservation and research in upland areas.

Published: March 2022

Over the last decades, the implementation of an environmentally-proactive behavior has taken on a new priority as part of the environmental planning strategies at higher education institutions. Nonetheless, this trend has exerted a heterogeneous impact on business education centres. Moreover, prior studies have found that administrators’ efforts play a crucial role to foster a school climate supportive of environmental proactivity. This paper contributes to investigate how and why universities, i.e. organizations not guided primarily by financial profits, decide to undertake an environmentally-proactive behavior. Specifically, we analyze deans’ perceptions in relation to the economic advantages that may be derived out of different levels of environmental proactivity of the centres. To that aim, we draw on a sample of 74 deans. Contrary to our original expectations, results reveal that there are no significant differences in deans’ perceptions of the economic advantages from their centres’ environmental proactivity.

Published: March 2022

The province of Bulacan, Philippines is considered as the biggest producer of used lead acid battery (ULAB) in the country and in Southeast Asia. But with the boom of the ULAB industry, a continued concern on the industry’s effect to human health and the environment intensifies. The study was conducted in two municipalities of Bulacan, Philippines to determine the perception of the respondents on the effects of lead recycling to their health and their community. These two areas are where ULAB industry is concentrated. Data were gathered from primary and secondary sources. Interview schedule using a structured interview guide and key informant interview were used. The respondents believed that there are toxic and hazardous substances used in lead recycling that contributed to their health problems and environmental pollution. Identified pathways of pollution include air, soil and water. But while they are aware of the health and environmental risks this industry brings, they also recognized its economic contribution to their families and their respective communities. The complexity of the problem continues to pose a challenge that needs to be addressed soon to balance economic prosperity and the communities’ welfare.

Published: March 2022

The participation of farmers residing in agrarian reform communities towards the use of selected IPB-bred vegetable and peanut varieties was assessed. Purposive sampling of 18 pre-selected farmers was done and were trained on seed production and cultural management practices of these varieties at the Institute of Plant Breeding. After the implementation of seed production activities in their respective places, it was found that there was a dramatic increase in the amount of vegetable and peanut seeds produced in Antique, Samar, Davao del Sur and South Cotabato. The amount of seeds produced by farmer participants from Samar was highest at 96.2%. In contrast, the farmer participants from La Union produced the lowest amount of seeds. In relation to climate change adaptation, based from survey, the farmers will be considering a few adjustments in the future implementation of farming activities like adjustments to be made in the planting calendar of these varieties by the farmer participants due to heavy rains occurring starting September every year. Also, farmers will implement utilization of the legume residues for composting to produce organic fertilizers, which was considered by all (100%) farmer participants. The peanut that can fix nitrogen from the air were also considered for crop rotation by majority (83.33%) of the farmers in order to lessen the use of inorganic fertilizers causing soil acidity. Further, the farmers indicated that peanut will be utilized for sequential cropping after rice to bring back soil fertility. All farmer participants from Antique, Samar, Davao del Sur and South Cotabato indicated the further adoption of the IPB-bred varieties in future production system. There was a highly significant association of the farmer participants’ selected demographic variables with the amount of seeds produced.

Published: March 2022

The effects of oil spill on the ecosystem and human lives are unprecedented. Early response and containment of the oil spill is the best approach in reducing the environmental impacts. This study assessed the diesel oil absorption capacity of Kapok fiber packed in Nylon net then tested the ability of a consortium of bacterial species reported to have oil degrading properties. To evaluate the conditions for the application of ex situ bioremediation, the hydrocarbon conversion was determined qualitatively by monitoring some possible degradation products with hexadecane as reference. Kapok (Ceiba pentandra (L.) Gaertn.) fibers packed in Nylon net were found effective in adsorbing diesel oil with a sorption capacity of 15.5 g g-1 fibers. A consortium of Bacillus megaterium, Corynebacterium flavescens, Micrococcus luteus and Pseudomonas putida with nutrient amendment (0.15 g N and 0.03 g P gram-1 oil) was used to determine preliminary oil biodegradation. Microbial population was sustained for six weeks and all species were found to contribute in the degradation process. Biosurfactant production was also observed in the seawater media. Gas chromatographic analysis showed some degradation products of the adsorbed diesel oil after one week of treatment. The use of Kapok sorbents for Tier 1 and 2 oil spill clean-up and its bioremediation done ex situ to degrade the diesel oil hydrocarbons can be an option.

Contaminated water from Manila, Philippines must be remediated. The use of peel wastes from Ananas comosus(L.) Merr. (Pineapple), Sandoricum koetjape Merr.(Santol) and Citrus nobilis Lour. (Dalanghita) , as agents in removing heavy metals from water could be cost effective. This study aimed to evaluate the capacity of peels to remove lead and cadmium in contaminated water. Furthermore, it aimed to determine the optimum pH, effect of contact time and the initial concentrations of heavy metals on the bio-sorption in the identified peels. The study was carried out by batch process. Biomass was added to known amounts of metals in solution with adjusted pH. After vacuum filtration, the filtrates were analyzed for residual heavy metal concentration using atomic absorption spectroscopy. Peel bio-sorption was optimum at pH 5. The amount of heavy metals adsorbed increased with time until 120 mins. The percent bio-sorption efficiency decreased with an increase in initial heavy metal concentration. The peels followed the pseudo second order kinetics, and the langmuir isotherm model with the bio-sorption of lead. For cadmium removal, pineapple and santol followed Langmuir isotherm model. For the actual contaminated tap water from Manila, santol showed the highest percent biosorption efficiency for lead and cadmium.

The relationship between economic growth and environmental quality is generally considered as linear, N-shaped or inverse-U-shaped curve. However, due to the effects of economic structure on economic growth and pollutant emission, this relationship may not be suitable in China. In this study, multivariate regression modeling was performed to identify relationships among pollutant emission, economic structure and economic growth in China. Estimates obtained from integrated multivariate regression results reveal that local provincial economic growth and pollutant emission demonstrate an inverse-N-shaped relationship that is different from that under the Environmental Kuznets Curve (EKC) hypothesis. Further empirical results also indicate that particularly in China; pollutant emission has a negative effect on economic structure and economic growth; pollutant emission can reduce the positive contribution of economic structure to economic growth; and enforcement of emission reduction policies could stifle economic transformation and maintain sustainable economic growth.
Assessing Rainfall Contribution to Storm Flow on a Small Forested Catchment in Republic of Korea

Published: March 2022

The TOPMODEL was employed to analyze rainfall contribution to runoff generation in a 58.3-ha Myeongseong catchment in Korea. The parameters of the model were calibrated using Monte Carlo simulation by comparing the observed and simulated runoff volume across nine recorded storm events. Parameter estimations gave the model an efficiency of 0.93 for the entire event set. Mean fraction of rainfall to storm flow was 23.1%, ranging from 5.6 to 48.3%. Variations were also observed in rainfall contribution related mainly to antecedent moisture conditions and other hydrological properties of the catchment. Quick response flow that was estimated from the saturated overland flow in the model comprised 41.9 -75.9% of the total runoff for nine storm events, while base flow accounted for 41.7% of streamflow for all events. No significant relationship between rainfall amount and quick response flow was found. This study introduced a modeling approach to identify the source of streamflow on a forested catchment. Difficulties in predicting accurately the runoff were encountered. In general, immense and high quality data are required to overcome the complexity of hydrologic processes that occur in forested catchments.
Motives for Firms to Adopt Solid Waste Management Controls: The Case of Food Processing Sector in Sri Lanka
Authors:   Wayamba University of Sri Lanka, Jayasinghe-Mudalige Udith , Udugama Menuka
Published: March 2022

This study offers an empirical analysis of the economic incentives available for food processing firms in Sri Lanka to adopt environmental controls for solid waste management. A series of in-depth interviews (n=325) were carried out with managers responsible for environmental quality in five types of food processing firms (coconut-based products, essential oils, non-alcoholic beverages, processed fruits and vegetables, and other processed products). Confirmatory Factor Analysis techniques were applied to the data to quantify the effect of six market-based incentives (cost/financial implications, sales, reputation, commercial pressure, human resources and technical efficiency), two regulatory incentives (existing and anticipated government regulations), and the liability incentive on the firm’s adoption of solid waste management practices. The level of adoption of environmental practices at the firm level is low -- on average firms adopt only 1.2 compared to the recommended eight different possible practices. Costs of adoption and perceived improvements in technical efficiency are two factors that motivate adoption. Liability laws and anticipated future regulations also matter. The analysis suggests that older and larger firms are more responsive to environmental considerations. Interestingly, export oriented firms do not do better than domestic firms.
Climate and Human-induced Changes to Lake Ecosystems: What We Can Learn From Monitoring Zooplankton Ecology
Authors:   University of Sto. Tomas, Papa Rey Donne , Briones Jonathan Carlo
Published: March 2022

Long-term time-series data have been proven useful in analyzing the adaptability of zooplankton communities as a response to environmental change. The unique life history and importance of zooplankton in aquatic ecosystems, coupled with the capability of lakes to integrate changes in the surrounding watershed, has given each the recognition as “beacons and sentinels of climate change,” respectively. Aside from this, many lakes have undergone pollution through human-induced eutrophication attributed to extensive lake-shore town development, agricultural waste runoffs, and intensive aquaculture. Implementation of holistic lake management plans in many countries has resulted to the rehabilitation and even reversal of lake eutrophication, and this is, in part, due to regular monitoring and careful analysis of temporal zooplankton community data that came with implemented rehabilitation efforts. As such, monitoring lake zooplankton populations may give us clues as to how changes in the environment, either from human or climate induced changes have already affected lake ecosystems. It is unfortunate however, that such analysis is presently not available in our country due to lack of routine zooplankton monitoring programs. The paper reviewed several successfully implemented lake/zooplankton monitoring programs, highlighted their strong points. The researchers also suggest integrative feasible concepts that are applicable to the country.

Today, electronic information flows, like many industries, are changing the role of libraries in society in a positive way. The role of the United Nations, UNESCO and IFLA in this regard is also fragmented. Just an example. It is known that the UN Sustainable Development Program has been adopted and is being implemented in many countries. The program has 17 goals. The goals of sustainable development can be said to be a call for specific action to be put forward by developed and developing countries.

Published: March 2022

The article deals with a new direction of research and publishing activities in Ukraine, such as the creation of regional branch encyclopedic publications. The author, focusing on the fact that this is mainly a local history direction and more than 70 editions have already been prepared, emphasizes that this work is gradually developing in the field of librarianship. Тhus, an important event in generalizing the experience of the development of the theory and practice of librarianship in Ukraine is the preparation and publication in electronic format of the nationwide “Ukrainian Library Encyclopedia” (UBE), which since 2010 has been created largely by the staff of the Yaroslav the Wise National Library of Ukraine. Leading librarians and practitioners of many scientific, public and specialized libraries, specialized universities and research institutes take part in the implementation of this project. Every year, the preparation of the UBE finds an increasing resonance in the professional circles of library specialists. Thanks to the work on the creation of this branch encyclopedia, new information about many outstanding figures in librarianship is introduced into the historical and scientific circulation; new directions of studying the history of libraries are developing, new terms of library science, new directions of library activity are characterized. To date, UBE has already published about 900 articles.

The importance of using a virtual reference service in the process of independent learning
Authors:   National Library Of Uzbekistan named after Alisher Navoi, Abdukakhorova Muazzam
Published: March 2022

The article announces the capabilities of libraries in the modern era. Thus, it is emphasized that today most of the library resources are adapted to the online mode, which makes it easier to access the database and special collections via a computer. Nowadays readers can use the personal account of the library without even leaving home. But this does not mean that remote access will reduce the demand for librarian support. Traditionally, it is natural for a user in need of expert assistance to feel the need for support even remotely. Therefore, it is advisable to create a modern virtual (or digital) reference service in conjunction with the traditional information service. Along the way, the author explains some of the new services in the library system. A virtual reference is a type of service that allows librarians and users to communicate in real time via the Internet, email, chat, or instant messaging. Improving all of these capabilities is the hottest topic in libraries today.

Published: March 2022

In the modern era of advanced information technologies, the issue of improving the culture of reading is becoming more and more urgent. The rapid processes of globalization are shaping a generation that, unfortunately, is far from the deeply rooted thinking in our lives. The article, however, emphasizes that the culture of reading plays a special role in developing immunity against such dangers, in increasing the spiritual and intellectual potential, consciousness and worldview of the younger generation. Using the example of print media, in particular, the newspaper “Vatanparvar”, the author draws attention to the importance of ensuring the comprehensive interests of the reader, especially the younger generation. As the author notes, the first thought is that the editorial board of the newspaper has begun to search for and implement important innovative solutions in this direction. It is gratifying that an important semantic role in the propaganda function of the publication is played by the formation of a reading culture among the country’s defenders. By an innovative solution, the author emphasizes, we mean a process that directly in the editorial office is aimed at popularizing reading. And in this direction in the article, the convergent materials of the publication are commented in detail.
