Leveraging Specialized Resources to Develop Innovative Library Services
Authors: Zhou Jia
Published: September 2024

Theme  libraries have emerged as a new service model to meet the demand from the public for a diverse service with resources that are both inclusive and specialized.  The "a library within a library" is currently the main practice model of theme libraries.  Influenced by that concept, the recently constructed and opened Suzhou Second Library includes a number of theme libraries, such as “Suzhou Literature Library," "Music Library," and "Design Library."  The establishment of these theme libraries within the Suzhou Second Library allows the library to build special community-focused collections that are culturally rich, to collaborate with local cultural organizations to create quality public programs that highlight the collections, and to actively engage the public with special events and exhibits surrounded by multimedia, digital special effects. These programmatic efforts have greatly improved public’s awareness of the valuable resources held at the library and thus increased the effectiveness of this new service model.

Published: September 2024

The use of smartphones, especially social media applications, has been widely used and used as a place to show what activities they do daily. From social media, the public can also see the activities of the celebrities they idolize. This has become a trigger for the community, especially students, to follow the lifestyle of their idols, for example in terms of fashion. The current fashion trend is very popular among students so that they still look cool and not out of date. Because they often follow fashion trends, students begin to be influenced by a consumptive lifestyle. To overcome this, self-control and financial literacy are needed to prevent students from behaving consumptively. This study aims to determine the effect of fashion trends, financial literacy, and locus of control on consumptive lifestyles. Data collection was carried out using a questionnaire distributed via Google Forms. The sampling technique used purposive sampling with a total sample of 185 respondents. The data were analyzed using multiple linear regression using SPSS 26 for Windows. The results showed that the fashion trend variable had a positive and significant effect on the consumptive lifestyle and the financial literacy and locus of control variables had a negative and significant effect on the consumptive lifestyle.
Keywords: trend fashion; financial literacy; locus of control; consumptive lifestyle; consumptive behavior.

Authors: Poh Stella , Hasan Djohan Gunawan , Sudiyono Krist Ade
Published: September 2024

Consumer shopping behavior has changed from brick-and-mortar to online shopping due to the COVID-19 pandemic. The development of online shopping was accompanied by social media technology, resulting in the emergence of the social commerce phenomenon. Social commerce, as a platform that supports two activities at once, has advantages over e-commerce platforms. However, in reality, the adoption of social commerce has not been utilized effectively by business actors, and not a few MSMEs have suffered losses due to the presence of social commerce platforms. This study was conducted to understand the adoption of social commerce platforms by utilizing social media content and live streaming to influence consumer purchases using the AIDA model and TAM model theories. This study uses quantitative methods by distributing questionnaires to 246 respondents and structural equation modeling (SEM) analysis techniques. The results showed that social media content and live streaming can inform consumers clearly and interestingly about products to build consumer attention and interest, which ultimately encourages consumer purchases. This study can be implemented by business owners to optimize the application of social media content and live streaming when running a business to increase consumer attractiveness and purchases.

Authors: Arif Nariswari Putri , Handayani Nur
Published: September 2024

This study analyzes the effect of economic, environmental, and social aspects of sustainability reporting on firm value, with financial performance as a mediating variable.  A sample of 20 companies from the basic materials and energy sectors listed on the Indonesia Stock Exchange from 2018 to 2022 was analyzed. Multiple linear regression was used to estimate the relationships among the variables, complemented by Sobel tests, to examine the intervening variable's mediating role and address the research gap. The findings reveal that environmental and social aspects positively and significantly impact a firm’s financial performance, unlike the economic aspect. Interestingly, the economic aspect negatively influences firm value, while the environmental aspect demonstrates a significantly positive effect, and the social aspect has no effect. Financial performance has a positive influence on firm value. Furthermore, the study finds that financial performance mediates the relationship between environmental and social aspects of sustainability reporting and firm value, not economic. These results highlight the crucial role of sustainability reporting in enhancing financial performance and ultimately creating long-term value for firms, particularly its environmental and social dimensions. The study emphasizes the need for companies to prioritize these aspects when crafting their sustainability reports to attract investors and achieve sustainable growth.

The green approach of nanoparticle preparation via biosynthesis method is known to be more economical, less toxic, and environmental-friendly as compared to the conventional chemical and physical methods which are hazardous and expensive. The advantages that are offered by this nanoscale material are their high surface area to volume ratio and the great stability which drive the performance to be effective. Among several nanoparticles, metal oxide namely tin (iv) oxide nanoparticles (SnO2 NPs) have attracted significant attention in recent years specifically in the nanotechnology discipline due to its wide applications in medical, catalysis, energy storage, coatings, sensors, dye-sensitized solar cells, and optoelectronics. The biosynthesis method was reported to be conducted using an aqueous extract of the green part of the plant, mostly the leaves and fruit segment. Within these plant parts, rich amounts of natural biomolecules are available that are capable of mediating the synthesis mechanism through capping and reducing action, which involves the chelating activity. Several characterization techniques were carried out to determine their unique characteristics in terms of crystallinity and morphological aspects such as XRD, TEM, SEM, EDX, FTIR, and UV-Vis. This paper summarizes the biosynthesis works of SnO2 NPs using leaves and fruit extract, and their properties were tested based on the photocatalytic performance as well as biomedical activities such as antimicrobial, antibacterial, antioxidant, and cytotoxicity.

Authors:   Department of Clinical Pharmacy, Faculty of Pharmacy, Universiti Teknologi MARA, 42300, Puncak Alam, Selangor, Malaysia, Rosli Nurbaiduri
Published: September 2024

Point-of-care pharmacogenetic testing (POCT) is a method employed by hospitals and community pharmacies for the detection of a patient's genetic profile related with drug response variability. The pharmacogenetic POCT has contributed significantly to the optimization of individualised medication therapy for patients. This strategy is extensively utilised in community pharmacies throughout developed nations, although Malaysia has yet to adopt it. The purpose of this study was to evaluate the knowledge, attitude, and practice of community pharmacists on the use of pharmacogenetic POCT in clinical practice. A cross-sectional study was conducted using a web survey comprising 36 items, with a response rate of 9.17% from 52 community pharmacists. The majority of respondents, predominantly females aged 31 to 40, exhibited diverse educational backgrounds and years of pharmacy practice. The study revealed a substandard level of knowledge, as indicated by a median score of 1. Despite this, participants displayed a positive attitude and eagerness to implement pharmacogenetic POCT in community settings. Notably, a statistically significant correlation was observed between knowledge and age (p=0.020), highlighting the need for targeted educational programs and training on pharmacogenomic POCT and its clinical application. To facilitate the optimal integration of this service locally, it is imperative to prioritize educational initiatives that enhance the understanding and application of pharmacogenetic POCT among community pharmacists. Addressing this knowledge gap can potentially revolutionize medication therapy, fostering a more personalized and effective approach to patient care.

Published: September 2024

En el siguiente trabajo de investigación se desarrolló un método para el análisis de luz natural. La motivación detrás de esta investigación radica en la escasez de programas diseñados específicamente para llevar a cabo este tipo de análisis. Si bien existen diversos programas disponibles para analizar la luz eléctrica o artificial, se ha recurrido al uso de un programa que originalmente no fue concebido para realizar análisis lumínicos. Sin embargo, debido a su enfoque en la calidad de representación de imágenes en modelos tridimensionales, este programa ha empleado análisis matemáticos y recursos de ecuaciones trigonométricas para simular la luz solar en un espacio virtual con características muy similares a las del sol. Como resultado, se han obtenido excelentes resultados en términos de representaciones gráficas. Para lograr estas visualizaciones, el programa en cuestión cuenta con herramientas como luxómetros, que permiten medir la luminancia e iluminancia en lux y candelas, respectivamente. Esto se realiza con el propósito de proporcionar confort visual y lumínico en el interior de los espacios arquitectónicos. Dado que en pocas ocasiones se disponen de imágenes previas con una calidad suficiente para representar con precisión el entorno, este enfoque se vuelve especialmente valioso. En el marco de este estudio, se llevaron a cabo análisis comparativos utilizando diferentes programas para corroborar la veracidad y efectividad de esta nueva herramienta en el análisis de luz natural.

This study investigates the impact of toll road construction on 59 micro, small, and medium enterprises in Kampar, Pekanbaru, and Dumai cities. The research aims to analyze the economic and environmental effects of infrastructure expansion on businesses’ profitability and sustainability, providing insights for policymakers and stakeholders to develop mitigation strategies to support MSMEs amidst ongoing infrastructure development. Structural equation modeling, spatial environmental impact analysis, and qualitative data analysis using five-level qualitative data analysis (FL-QDA) were all used together in a mixed-methods approach. Data collection involved observations, interviews, questionnaires, and geospatial analysis, including the use of a Geo-Information System (GIS) supported by drone reconnaissance to map affected areas. The study revealed that the toll roads significantly enhanced connectivity and economic growth but also negatively impacted local economies (β = 0.32, R2 = 0.60, P-value ≤ 0.05). and the environment (β = 0.34, P-value ≤ 0.05), as 49% of respondents experienced a 50% decrease in profitability. To mitigate the risk of impact, policymakers should prioritize the principle of prudence to evaluate the significance of mitigation policy implementation (β = 0.144, P-value ≥ 0.05). In a nutshell, toll road construction significantly impacts MSMEs’ business continuity, necessitating an innovative strategy involving monitoring and participatory approaches to mitigate risk.

Authors: Zhang Mengzhong , Kaur Manpreet
Published: September 2024

This paper examines the transformative potential of e-government in public administration, focusing on its capacity to enhance service delivery, transparency, accessibility, cost efficiency, and civic engagement. The study identifies key challenges, including inadequate technological infrastructure, cybersecurity vulnerabilities, resistance to change within public institutions, and a lack of public awareness about e-government services. These barriers hinder the seamless operation and adoption of digital government initiatives. Conversely, the study highlights significant opportunities such as streamlined service delivery, enhanced transparency through real-time access to government data, increased accessibility for marginalized and remote communities, substantial cost savings, and greater civic engagement via digital platforms. Addressing these challenges through targeted strategies—enhancing technological infrastructure, bolstering cybersecurity, managing organizational change, and raising public awareness—can help policymakers and public administrators implement more effective and inclusive e-government initiatives. Additionally, the integration of these digital solutions can drive sustainable development and digital inclusion, fostering social equity and economic growth. By leveraging these opportunities, governments can achieve more efficient, transparent, and accountable governance. Ultimately, the successful implementation of e-government can transform the relationship between citizens and the state, building trust and fostering a more participatory democratic process.

Published: September 2024

Introduction: An endoscopic intragastric balloon (IGB) placement is one of the minimally invasive methods of obesity treatment. One of the rare serious complications is mechanical bowel obstruction requiring operative management. We report a case of a male patient with small bowel obstruction due to IGB migration and the literature review of complications during IGB treatment. Detailed Case Description: A patient with a BMI of 28 kg/m2 was admitted to the hospital with spontaneous deflation of an IGB. Due to the suspected location of IGB in the ileum laparoscopy was performed. The enterotomy was performed and the IGB removed. The procedure and the postoperative period were uneventful. Discussion: Spontaneous IGB ruptures are reported in the literature with a frequency ranging from 0.6 to 23%. The majority of deflated devices are spontaneously excreted with the stool with no abdominal symptoms. Only 0.38% of IGBs cause mechanical bowel obstruction of requiring surgical management. Based on our own experience and literature review, we propose the diagnostic and therapeutic algorithm. Conclusion: Complications after IGB placement can range from mild to severe, that is why it is so important to make an early diagnosis based on the emerging symptoms and to implement prompt management to reduce or avoid serious complications. Any patient reporting disturbing symptoms occurring over a prolonged period of time requires hospitalization and careful observation for the occurrence of gastrointestinal obstruction. The ideal option is hospitalization in the center which implemented the IGB and start with the algorithm we proposed.

Published: September 2024

The effect of feeding spray dried porcine plasma (SDPP) to male turkeys during the first 4 weeks of life was evaluated at 20 weeks of age. A total of 648 male Hybrid Converter day-old turkeys were divided into two groups of 9 replicate pens of 36 birds each, and fed a commercial- type program of 7 diet phases. In phase 1 birds were fed a corn-soybean meal Control diet for 4 weeks, or a diet with 2% SDPP of similar nutrient density. Thereafter, both groups were fed common diets until the end of the trial at 20 weeks of age. At 4 weeks of age, birds were subjected to heat stress and crowding for a period of 24 hrs to simulate the stress induced commercially when moved from the brooder house into a grow-out building. Poults fed SDPP had greater body weight (BW) and body weight gain at 6 (p<0.05) and at 9 weeks of age (p<0.10). At 20 weeks of age, BW of turkeys fed SDPP vs Control was not different. However, the European Productivity Index (EPI) that incorporates final body weight, feed conversion ratio and livability, tended to be higher (p<0.10) for the SDPP group (EPI = 545 vs 529, respectively) because of the higher livability trend exhibited in SDPP group (96.91 vs 94.75%, respectively). Likewise, birds fed SDPP showed significantly lower frequency of foot pad lesions vs Controls (p<0.05) by the end of the study. In conclusion, SDPP fed early in life can reduce stress, improve performance and reduce incidence of foot pad lesions in turkeys.

Published: September 2024

This study analysed the influence of montelukast (MON), a cysteinyl leukotriene receptor antagonist, and nifedipine, an L‐type voltage‐gated Ca2+ channel blocker, on the contractility of the porcine uterine smooth muscle. Myometrial strips were collected from the sexually immature (n=8), cyclic (12-14 days of the oestrous cycle; n=8) and pregnant (27-28 days of pregnancy; n=8) gilts and stimulated with a) MON or nifedipine at concentrations of 10-8-10-4 M and b) increasing concentrations of nifedipine after previous administration of MON at a concentration of 10-4 M. The changes in the tension, amplitude and frequency of contractions were determined with the Hugo Sachs Elektronik equipment for measuring isometric contractions. Stimulation of the uterine strips with high concentrations of MON significantly reduced the amplitude of contractions in both the cyclic and pregnant group and the frequency of contractions in the pregnant group. In high concentrations, nifedipine significantly decreased the amplitude and frequency of contractions in all examined groups. Nifedipine administered after MON pre-treatment significantly decreased the tension in the pregnant group and the amplitude and frequency of contractions in all examined groups; this effect was more evident in comparison with nifedipine used alone. The results obtained indicate that the influence of MON and nifedipine on the contractile activity of the porcine uterus is dependent on the physiological status of the animal. Moreover, the blockage of the CysLT1 receptor enhances the relaxing effect of nifedipine.

Published: September 2024

Salmonella spp. is an important zoonotic and foodborne pathogen. It is spread worldwide and represents a public health risk. Pigs are a significant reservoir and are frequently subclinical carriers. The aim of this study was to detect the occurrence and antimicrobial resistance of Salmonella isolates being the five most important for public health Salmonella serovars in fattening pigs in Bulgaria. The isolation of Salmonella spp. was carried out according to EN ISO 6579-1 for the detection of Salmonella bacteria in feces and Salmonella serotyping following the Kauffmann-White scheme. All confirmed S. enterica isolates were analysed by the disk-diffusion method for susceptibility to 14 antimicrobials. Salmonella enterica was detected in 13 out of 32 tested farms in Bulgaria. The overall percentage of Salmonella positive pooled fecal samples was 6.8% (43 of 630 samples). The highest occurrence was present in fattening pigs aged between 121-180 days (16.3%; 20/123), followed by dry sows (6.5%; 4/62) and gilts (4.8%; 12/248). About 75% of the isolated strains belonged to three serotypes: Salmonella Infantis (41.9%), Salmonella Give (16.3%) and Salmonella Typhimurium monophasic (16.3%). All the tested isolates were resistant to Tilmicosin (100%), 88.4% to Ampicillin, followed by 69.8% to Tiamulin, 25.6% to Amoxicillin and Chlortetracycline. Multidrug resistance was recorded in 62.8 % of the tested strains. This study reports data regarding the circulation of the most important for public health five Salmonella serovars (S. Enteritidis, S. Typhimurium, S. Typhimurium monophasic, S. Infantis and S. Derby) in farrow-to-finish pig farms in Bulgaria and represent 74.4% of the total Salmonella spp. isolates. This phenomenon has critical effects for the health of consumers and therefore represents a key “one health” issue.
Integrated analysis of differential gene expression profiles in porcine alveolar macrophages induced by Mycoplasma hyopneumoniae strain 232
Authors: Wang G. , Li J. , Liu Y.
Published: September 2024

Porcine alveolar macrophages (PAMs) can resist infection caused by Mycoplasma hyopneumoniae (Mhp) through phagocytosis. However, it is unknown what gene expression changes occur in PAM after Mhp stimulation. Therefore, the differential gene expression (DGE) profiling technique was employed to analyze differentially expressed genes in PAMs infected with Mhp strain 232. Eighty-six and 889 differentially expressed (DE) genes were identified in PAMs at 12 hours post-infection (hpi) and 24 hpi. Using Gene Ontology (GO) analysis, DE genes were involved in 54 (12 hpi) and 128 (24 hpi) GO enrichment items. Using Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, DE genes were involved in 101 (12 hpi) and 250 (24 hpi) KEGG enrichment items. Using Ingenuity Pathway Analysis (IPA), DE genes were connected, forming 25 internally interacting subnetworks. STRING analysis revealed 131 proteins encoded by DE genes involved in network interactions. Five novel genes were closely related to clinical symptoms and pathological changes of Mycoplasma hyopneumoniae. This is the first study to investigate PAM transcriptional responses to Mhp infection using the DGE profiling technique.

Published: September 2024

The outbreak and prevalence of tembusu virus (TMUV) endanger the breeding industry of waterfowls. However, little is known about the molecular mechanism underlying TMUV infection. It was reported that heat shock protein 70 (HSP70) was a positive regulator of the infection of TMUV. In order to study the interactions between HSP70 and host immune response to TMUV infection, TMUV-infected cells with or without HSP70 inhibitor were harvested and subjected to deep sequencing to identify genes differentially expressed. We found 43 differentially expressed genes (DEGs) in HSP70 inhibitor-treated and mock-treated TMUV-infected DF-1 cells. Of these DEGs, 39 genes were down-regulated significantly. Gene Ontology analysis suggested that the DEGs were mainly involved in biological process, cellular component and molecular function. Kyoto Encyclopedia of Genes and Genomes analysis showed that the DEGs mainly related to the activation of innate immune response, including RIG-I-like receptor, toll-like receptor and NF-κB signaling pathway. Also, 12 down-regulated immune-related DEGs were selected for confirmation by reverse transcription quantitative real-time PCR verification, all these genes showed consistent expression between the result of reverse transcription quantitative real-time PCR and transcriptomic sequencing. These results revealed the important role of HSP70 in facilitating the innate immune response induced by TMUV infection. This is first to access the role of HSP70 in host response to TMUV infection, which provides a basis for further study of the pathogenesis of TMUV and contributes to the elucidation of TMUV-host interactions.

This study focused on continuous monitoring of the immunocontraceptive effect of Improvac ® vaccine on the sexual activity of male goats determined by measuring plasma testosterone levels, testicular biometric and ejaculate examination. The animals in the experimental group (n=12) were administered two doses of 2 ml of Improvac® at a four-week interval; the animals in the control group (n=5) received 2 ml of saline. Blood collection, semen collection and testicular measurements were performed at 14-day intervals. A total of 8 samples were collected from each animal. In 9 animals a significant decrease (p<0.05) in testosterone concentration was observed two weeks after the first dose. At the end of the experiment (16 weeks), eight goats reached a testosterone concentration below the detection limit and one goat had a concentration of 0.47nmol/L. The testicular size was significantly (p<0.01) smaller four weeks after the first dose. At the end of the experiment, the testicular size was approximately three times smaller (p<0.001). Motility was 0% in two goats at the end of the experiment, 1% in one animal and 10% in one animal. The median sperm concentration was significantly lower (p<0.01) at the end of the study. A significant (p<0.0001) shift in the percentage of morphological changes was recorded eight weeks after the first administration. At the end of the study, there were five animals with azoospermia, two with 100% morphologically altered sperm, one with 99% and one with 96% morphologically altered sperm. In the three male goats, a significant skin reaction occurred after the first application, which resulted in an inadequate response to the treatment. Our results show that Improvac had a significant effect on the sexual function and sperm production in 9 out of 12 male goats.

The aim of this study was to investigate the activity of thymoquinone (TQ), carvacrol (CAR) and thymol (TYM) against multi-drug resistant nontuberculous mycobacteria (MDR-NTM), alone and in combination with berberine (BER). Antimicrobial activity was first evaluated at concentrations from 8 to 512 μg/mL. Each of the compounds tested exhibited good activity against nontuberculous mycobacteria (NTM) isolated from fish, with MIC values of 32-128 μg/mL. In this study, we have shown for the first time the synergistic efficacy of BER with CAR, TYM or TQ against NTM strains. Thus, the combination of these compounds with BER seems to be a new approach for combating MDR-NTM strains.

Bisphenol A (BPA), an endocrine disrupting chemical, is an environmental toxicant widely used in the production of polycarbonate plastics, epoxy resins and paints. Ganoderma lucidum (GDL) is a plant with biological activities widely used in Chinese medicine. The present study aims to determine the effects of GDL against testicular dysfunction in rats exposed to BPA. For this purpose, a total of 24 Sprague Dawley rats, 6 rats in each group, were used in the study. Rats were administered 25 mg/kg/bw BPA and 300 mg/kg/bw GDL by oral gavage for 8 weeks. After the treatments, the rats were sacrificed, and testicular tissues were removed. One of the testes was used for biochemical analyses and the other for histopathologic examinations. The caudal part of the epididymis was trimmed, and semen was obtained. As a result, BPA increased MDA level in blood and testicular tissue, while it decreased CAT, GPx activity and GSH level. GDL treatment provided protection from the impaired oxidant balance (p<0.001). Furthermore, BPA caused decreased epididymal sperm motility and density, vesicular seminalis weight and blood testosterone levels, increased testicular and epididymal tissue weight (p<0.001). Histopathological examination revealed that BPA caused narrowing in testicular tubules and apoptosis, decreased germinal cell thickness and androgen receptor number. It was determined that GDL administration preserved testicular histology. As a result, it was determined that BPA caused toxicity in the testicular tissue of rats, whereas GDL administration was ameliorative.
Stern, Gamow, and the Shabbat Elevator Effect
Authors: Georgiou Loukas
Published: September 2024

In addition to being known for their other work, physicists George Gamow and Marvin Stern also published an analysis of an intriguing problem regarding their perception that although both worked on different floors, it seemed that the first elevator to arrive on their respective floors was traveling in the opposite direction of their destination. In this manuscript, a fictitious conversation occurs between the two in regards to the probability of the elevator stopping on every floor (which they term the Shabbat Effect). One claims that it is the number of elevator occupants that predominates whereas the other claims it is the number of floors in the building that predominates in giving rise to this effect. Equations for estimating the probability of the Shabbat Effect are developed and analyzed. The resulting equations show that the relationship between the number of elevator occupants and floors is surprisingly complicated. Consequently, no general rule can be given for whether the probability of the Shabbat Effect increases or decreases for an arbitrary change in the number of occupants and floors. However, it discovered that for similar changes in the number of occupants and floors, it is the number of floors that predominates in determining the probability of the elevator stopping on every floor.
