Service quality comes from a comparison between customer expectations about the service they should receive with the service they actually get. An important service unit in state universities such as the University of Jambi is the library service. The library is a service unit that provides services in the field of literature. The needs of library users, especially students, for science and other educational media are difficult to separate. Therefore, the library is one of the academic support facilities needed by library users such as students and lecturers. Based on the results of observations, various efforts have been made by the FST UNJA’s Library to improve services, but these improvements are still not optimal. Therefore, it is necessary to analyze the factors that influence service quality to assist the FST UNJA’s Library in reviewing the factors that affect service quality. The Structural Equation Modeling (SEM) method is a multivariate statistical method that can be used to look at the factors that influence the quality of the service. SEM is an appropriate analysis used in social research. In this study, there are two exogenous variables used, the first is employee competency which has manifest variables to measure it, such as knowledge, understanding, ability and attitude. The second is library facilities that have manifest variables to measure them, namely library space, library equipment and reading book collections. As well as the endogenous variables used in this study is the quality of service which has five manifest variables of reliability, responsiveness, assurance, empathy and tangible. The research data is primary data obtained by researchers by distributing questionnaires to visitors to the FST UNJA’s library

Global approach to qualitatively new consideration of the problem of food security of the Republic of Kazakhstan and state of agro-industrial complex, which in the current conditions needs to find and implement effective forms and mechanisms of state regulation and support for agricultural producers in order to stabilize domestic food market - all this becomes particularly relevant. The goal is to develop comprehensive methodology for analyzing food problem in the republic based on system of indicators that determine current situation and assessment criteria. Methods – monitoring the correlation between main parameters and threshold values. The availability of food (financial, economic, physical), quality and food safety, and availability of resource potential of agro-industrial production were taken into account and analyzed. Results - it is noted that the degree of financial affordability of food products for employed population and retirement age has decreased; coefficients assessing economic accessibility of food products are within normal limits. At the same time, physical accessibility indicators indicate difficulties with food supply. Conclusions - it was revealed that the level of food supply in Kazakhstan exceeds the average data in the countries of Central Asia. The food program is complex and multi-factorial, including economic, social, cultural and environmental indicators. By maintaining competitiveness of national producer, country gains the opportunity for more sustainable and efficient development of its own agricultural sector. Assessing the parameters of the effective functioning of AIC becomes main content of monitoring process, based on the results of which one can judge the possibilities and prospects of providing the population of the Republic of Kazakhstan with food in the required volume of quantitative and qualitative aspects of their needs.

Methods – comparison of calculated levels of dynamics of economic activity of an economic entity, abstract-logical, generalizations. Results - the state of the existing mechanism for providing budgetary funds to agricultural formations is analyzed. The trends in receiving financial assistance from the state are considered based on the use of information about their goals, strategy and competitiveness. The parameters of production of crop and livestock products at the analyzed facility over the past five years have been studied; for the same period, the volumes of funding received have been indicated, the amounts of which are not stable over the years; a direct relationship between the increase in the amount of subsidies and the increase in the volume of products produced has been substantiated. The one-sided nature of the amounts of financial investments provided, which are focused mainly on the crop production industry, is noted. The author states that despite the decrease in production indicators, there is a significant increase in gross and net profit, which helps improve the financial position of the agricultural company. Conclusions - as measures to improve the system of providing financial support to agricultural producers, it is advisable to increase public investment in agricultural enterprises in priority areas, primarily for the production of livestock food products, as well as to reduce interest rates; provide for the issuance of loans for the development of livestock farming. To ensure the sustainable functioning of an agricultural enterprise, an effective economic instrument is needed, based on a combination of state regulation and self-control, and the implementation of a balanced pricing and financial and credit policy.

The study of formation and effective development of agricultural cooperatives in rural areas is of particular importance in the context of improving the legislative and legal mechanism for increasing the competitiveness of agricultural industry, effectiveness of mutually beneficial economic relations, and promotion of cooperative processes in agro-industrial production. The goal is to substantiate the need to optimize the system of state regulation and support for agricultural cooperation. Methods – analytical, monographic, comparison and generalization. Results show the problems that make it difficult to unite small forms of farming in rural areas: low labor productivity, limited access of farmers to technical and information resources and services, lack of modern equipment. The authors note that regulatory governance and oversight, financial support, advisory services and training are needed. Conclusions - cooperation of medium and small enterprises is the only opportunity to produce a modern and competitive product comparable in cost to the products of large agricultural producers. They are of great socioeconomic importance, since they provide employment to a significant number of villagers, contribute to their effective functioning in a market economy through the expansion of agricultural production, the growth of competitive potential, which facilitates entry into the market, ensuring the profitability of business entities, and allows solving issues of import substitution and development of the infrastructure of RS, improving the level and quality of life of the rural population. Such cooperatives adapt their operations to agricultural technological innovations in the use of fertilizers, growing crops and livestock, agricultural mechanization, and the use of new resource-saving energy sources and communication systems. Small farms united on cooperative principles can fully demonstrate their inherent advantages in the future.

The snack sector has a significant market today. It is expected that the snacks will look as promised on the packaging and that the product will have no deformations or defects. The entire area of liquid chocolate- covered snack products entering the chocolate cooling tunnel must be cooled homogeneously. If all surfaces of the chocolate are not sufficiently cooled, a problem of sticking to the conveyor belt can occur. This study investigates the performance of roll-bond heat exchangers under different operating conditions to solve the snack sector’s technical problems. For this purpose, a CAD model of a roll-bond heat exchanger is created. A steady-state heat transfer problem is established in the SolidWorks Flow Simulation environment, and the problem is solve numerically. The maximum, minimum, and average values of the fluid temperature, pressure difference, fluid velocity, and solid temperature distributions are calculated for different inlet velocities and temperatures. In addition, the standard deviations of the solid temperature values are calculated and evaluated. The results show that the roll-bond heat exchanger applies to the chocolate cooling tunnel and is much more efficient for heat transfer than the conventional design.

In light of the ever-increasing problem of environmental pollution, photocatalysis represents one of the most promising solutions for the remediation/decomposition of wastewater pollutants. Among the materials used for the photocatalytic degradation of organic pollutants, titanium dioxide has been widely investigated due to its unique and favourable properties. On the other hand, its limitation in absorbing only about 5% of solar light and its relatively wide band gap and rapid recombination of electron-hole pairs restricts its practical application. In order to overcome this drawback and improve photocatalytic ability, various methods have been investigated. Some of the significant methods that have been extensively studied over the past decades involve the preparation of binary oxides, mixed oxide systems, composite materials, etc. This short review provides a comprehensive summary of scientific reports of titania-ceria composite materials and their applications in photocatalytic reactions reported in the literature.

Phthalic acid esters (PAEs) are organic compounds extensively used as plasticisers. Their widespread use has resulted in their presence in aquatic and terrestrial ecosystems, making them a high-risk pollutant. PAEs are detrimental to human health as they disrupt the endocrine system and can potentially cause cancer. Although their impact on humans is relatively well-known, more research is necessary to comprehend their effects on phytoplankton. This work aimed to examine the influence of different concentrations (50, 100, 150, 200, 250 µg/L) of benzyl butyl phthalate (BBP) on the growth of several most common phytoplankton species (Microcystis sp., Anabaena variabilis, Chlorella sp., Scenedesmus sp.) in laboratory conditions. Phytoplankton growth was monitored spectrophotometrically to determine the concentration of chlorophyll a. The results showed that higher concentrations of BBP significantly inhibited the growth of A. variabilis and Microcystis sp. Green algae showed a considerably lower sensitivity, especially Chlorella sp., where significant growth inhibition was not observed. After the experiment, the detection and quantification of BBP in extract samples were performed using gas chromatography with mass spectrometry (GC-MS). BBP was detected only in the extracted sample with Scenedesmus sp., but the detected concentration was insignificant. The results indicate that all tested organisms could probably absorb and metabolize BBP, of which Scenedesmus sp. has the least ability.

Investors and service providers in the cryptocurrency market are exposed to significant risks. High volatility, technological characteristics and anonymity create: investor risk, risk associated with money laundering and financing of terrorism and systemic risk. The market is full of fraudsters and there are too few adequate rules to protect investors and prevent market manipulation and insider trading. Also, the value of cryptocurrencies is very volatile, and their prices change from day to day. Investors in cryptocurrencies are exposed to higher risks of loss than investors in other assets. Cryptocurrencies can potentially be used for money laundering and financing of terrorism. Negative consequences can be reflected through economic as well as overall social disruptions that manifest themselves through disruption of the monetary system, economic and social stability, transparency and efficiency of the financial system, etc.

The development of technologies and the Internet conditioned the development of video surveillance systems. In modern video surveillance systems, the complete content recorded by a camera can be publicly available, i.e., visible on the Internet. The mass use of this type of camera has led to the fact that the cameras record everything and everyone and that the recorded content violates privacy. In order to protect privacy, different types of technologies and software are applied. One of those technologies is machine learning. By applying machine learning, it is possible to mask people's faces on recorded material. In this way, in publicly available content, as well as in case of unauthorized access, the identity of people is not compromised. This paper describes the architecture of a system that enables the application of machine learning for the purpose of protecting the identity of a person, where only an authorized person would have access to the original unmasked content.

Purpose: To assess the awareness of diabetic retinopathy among Type 2 diabetes mellitus from central India.

Method: A cross-sectional study involving 350 patients with type 2 diabetes mellitus was conducted between August 2022 and January 2023. Participants completed a 21-point questionnaire on diabetic retinopathy awareness and knowledge. Results were expressed in frequencies and percentages.

Results: 54.3% (190 participants) had awareness about diabetic retinopathy. Education significantly influenced awareness, with 72% of educated participants showing higher awareness. 66% of urban residents were more aware than 47.1% of rural residents. No significant gender difference was observed. Younger participants demonstrated better awareness (63.9%) than older individuals (17.3%).

Conclusion: About 54.2% of the participants were aware of Diabetic Retinopathy (DR). Younger patients, patients from urban areas and the group with a higher level of education were found to be more aware of DR. Effective health education and regular eye screenings are essential to improve awareness about DR, aiding in its prevention and better disease management among individuals with type 2 diabetes.
Review of Thyroid Cartilage Compression of the Vertebral Artery
Authors: Kong Leon
Published: January 2024

Thyroid cartilage compression of the Vertebral Artery (VA) has been implicated as a rare cause of Rotational Vertebral Artery Occlusion (RVAO). 10 cases have been reported in the literature. This has a higher tendency to affect males and younger patients than other forms of stroke. Patients present with multiple episodes prior to diagnosis. Radiologic studies prove crucial for confirming this condition. An aberrant VA course appears to be a necessary factor. All cases suffer from right side VA compression by the superior thyroid cornu. Conservative therapy with antiplatelet treatment is employed commonly. Most patients have definitive treatment with surgical resection of the right superior thyroid cornu. Theories proposed for these characteristics include VA dominance, structural variability in the thyroid cartilage between genders and also variable thyroid cartilage ossification. Given these findings, we propose the term “thyro-vertebral artery syndrome” for this condition.

With various policies issued by the government to limit the space for people to move in order to prevent the spread of the virus, this has made people, including female students, more stimulated to shop online. One of the e-commerce that was popular even before the Covid-19 pandemic was Shopee. Moreover, Shopee provided Shopee Pay Later (Spay Later) feature. While numbers of existing literatures deal with purchasing decision using quantitative approach and consumer legal protection, this article is focused on how female students interested in using Spay Later and how this impacted on their life.
This research was conducted between September 2021 and March 2022 through social media regarding the Shopee application, using a qualitative approach. There are 15 female students who participated in this research and who use Spay Later. Data was collected using in-depth interview and observation.
The study indicates that online shopping through Spay Later has increasingly stimulated because Shopee has a Spay Later feature that makes shopping easier during pandemi Covid-19. One of the Spay Later users who use this application a lot is female college students. They use Spay Later because of the convenience of shopping provided by Shopee, both in terms of shopping and payment methods. Discounted prices and postage are another reason why Spay Later is a shopping choice for female students. So even though they have no intention to shop, these offers stimulated them to shop. Shopping by using Spay Later is also an option because of the availability of various goods, anything is sold at Shopee, so shopping is like a “one stop shopping” without having to go anywhere and even if they do not have enough money to shop.  It carries the slogan: "Buy Now Pay Later". However, the use of Spay Later has impacted on its users, both positively and negatively. While the former includes save energy and time because they don't have to leave the house; the latter consists of  the emergence of concerns and the tendency to behave consumptively.  When the due date is approaching but they have not yet received remittances from their parents, the concerns are mounted because they not only have to pay the total price of the goods, but also pay arrears of 5% of the price of the goods. In addition, with the various conveniences provided by Shopee and Spay Later, shopping depends on the tip of the index finger, when a person cannot control herself, it will be very easy to get caught in consumerism. Therefore, female students must learn to manage their finances and learn to be able to refrain from prioritizing desires over needs.

Indonesia is one of the countries with a fairly large number of K-pop fans, which is also supported by a significant number of social media users. These two aspects create a phenomenon that is popular among fans who are active on social media, named roleplayers. Roleplayer is a term that refers to K-pop fans who create a fictional figure through a new identity on social media and live their lives and roles through such identity while keeping their true identity a secret. This article focuses on the virtual communication method that roleplayer has improved from K-pop fans.
This study was conducted between March and July 2022, involving 18 informants who were interviewed through Zoom Meeting and Goggle Meet. Virtual participant observation was also carried through Twitter as one of the most dynamic and crowd social media with the researcher being a roleplayer and observing the uploads of roleplayer accounts and being directly involved in their communication.
The roleplay performed by K-pop fans on social media Twitter is a fictional figure with a new identity called a roleplayer. Roleplayers live a double life with different identities, one as a roleplayer who "lives" in a virtual space and the other is a real self who lives in an actual space. Their lives in the actual world with real identities are called real life, while the roleplayer world is a "space" where they "live" with a fictional identity. Roleplayer identity and real identity must be strictly separated so that life in the roleplayer world and real life do not intersect with each other. In an effort to develop identity, roleplayers create story lines, namely a series of essays of events/stories made by roleplayers, so that it is as if the essay is a "journey of life" for them. In addition, roleplayers also establish relationships with other roleplayers, both personally and in groups. Communication is needed in carrying out these relationships. However, because the existence of roleplayers only revolves around Twitter and closes themselves to direct interaction, their method of communication is limited to text by utilizing Twitter features. However, roleplayers strive to be able to communicate as much as possible by improvising their communication methods through the use of special terms and abbreviations, imagining through text, and visualizing the text through images or videos. Basically, all identities attached to roleplayers are just fantasy or fictitious being transferred to a virtual space. But all the affection felt by the roleplayers is real, especially when a roleplayer is in a relationship with other roleplayer. Therefore, the fantasy that exists in the relationship becomes a "common property" fantasy that is connected to each other.
