Authors: Haryanti Ni Putu Premierita , Suhartika I Putu
Published: February 2023

This study examined how librarians at university libraries in Bali used e-DDC. This objective of the study was to ascertain how often e-DDC is used among university libraries and what factors affect that utilization. This study used a descriptive quantitative approach. All members of the library staff or librarians who had utilized e-DDC at university libraries in Bali made up the population and samples used in this study. Total sampling was the chosen sample method. The data were obtained through questionnaires, observations, and interviews. The findings of this study demonstrated that the library personnel preferred using printed DDC over electronic ones. As a result, they do not profit fully from using e-DDC. This was due to the fact that the information in printed DDC is more comprehensive than that in electronic form, making e-DDC utilization less than ideal. External factors like user training, accessibility, term clarity, and convenience of use affected how e-DDC was used. The DDC system must be re-maximized (upgraded) as a result, and the librarian or other library personnel must also be more receptive and adaptable to the current system in the library. The main purpose of using e-DDC is to make it simpler for users to find the needed classification numbers and to improve the processing section's unit.

To meet the demands of the workplace, archivists need to understand how soft skills develop. Digital technology development is a task that needs to be accelerated right away. This article attempts to discuss the findings of studies on how archivists work from home (WFH) during the COVID-19 pandemic in Indonesia led to developing soft interpretative skills. A case study approach was employed in this descriptive qualitative research. Questionnaires and interviews were used as the primary data-collecting methods for samples from the local government, the business sector, and ANRI. The findings demonstrated that the perception of soft skills has evolved into an implicative function rather than a meaning-based one. Based on the study's findings, it was determined that soft skills provide an essential and crucial purpose, precisely the demand for digital literacy. It was also determined that the implementation of WFH during the COVID-19 pandemic demonstrated the use of digital literacy abilities.

Published: February 2023

This paper attempts to understand the progressivity of economic regionalism in Southeast Asia. Unlike previous researches, this paper will explain how the complexity of Southeast Asia region affecting liberalism in ASEAN. This can be seen from how the mega-regional competition between TPP and RCEP hinders ASEAN centrality, signified by the fact that Vietnam, Singapore, Malaysia, and Brunei chose to participate in both cooperation, despite knowing that RCEP should be part of ASEAN centrality agenda. This paper will pay attention on two types of condition: (1) understanding the transformation into mega-regional partnership in Asia-Pacific; (2) understanding the decision of four ASEAN countries who choose to participate in both mega-regional models. The theory which will be used in this paper will be the ‘new trade strategy’ developed by Aggarwal and Lee (2011). In the end, this paper finds that there is a renewal in perception, interest, and domestic institution in the creation of RCEP and TPP. Meanwhile, the decision of Vietnam, Malaysia, Singapore, and Brunei to participate in both RCEP and TPP is the result of rational calculation in terms of economic advantage, political economy, domestic structure improvement, and security. These four calculations can be seen in all country, especially those who utilize greater economic liberalization.

Authors: Flis-Olszewska Ewelina
Published: February 2023

Głównym celem pracy była analiza warunków termicznych w okresie 1960–2019 na stacji pomiarowej Lublin-Felin oraz porównanie zmian temperatury powietrza ze zmianami liczby przymrozków wysokich (200 cm n.p.g) i niskich (5 cm n.p.g.) oraz długości okresu bezprzymrozkowego. Zaobserwowano tendencję wzrostową średniej rocznej temperatury powietrza wynoszącą 0,5°C/10 lat, a jednocześnie spadek liczby przymrozków wysokich w tempie –1,4/10 lat oraz przymrozków niskich o –2,4/10 lat. Długość okresu bezprzymrozkowego na przestrzeni wielolecia ulegała stopniowemu wydłużeniu o ok. 4 dni/10 lat. W przypadku dalszego wzrostu temperatury powietrza można spodziewać się dalszego spadku liczby dni z przymrozkami, jak również wzrostu długości okresu bezprzymrozkowego, który będzie rozpoczynał się wcześniej, a kończył później niż obecnie.

Authors: Kraska Piotr , Andruszczak Sylwia , Gierasimiuk Paweł , Chojnacka Sylwia
Published: February 2023

Badania przeprowadzono w latach 2015–2017, opierając się na eksperymencie polowym założonym jesienią 2014 r. w miejscowości Rogów (powiat zamojski). Celem badań była ocena wpływu podpowierzchniowego wprowadzania zróżnicowanych dawek wieloskładnikowego nawozu mineralnego Polifoska®6 NPK(S) 6-20-30(7) na plon oraz wybrane cechy jakości plonu nasion soi. Soję wysiewano w zmianowaniu soja – pszenica ozima – kukurydza w warunkach uprawy bezorkowej. Nawóz mineralny w dawce 200 i 400 kg∙ha–1 wnoszono pod powierzchnię gleby równomiernie w zakresie 10–30 cm głębokości pracy elementu wysiewająco-spulchniającego. Obiekt kontrolny stanowiły poletka z powierzchniową aplikacją nawozu. Po zbiorze oceniono plon i elementy struktury plonu. Wykonano również analizy chemiczne nasion soi celem określenia jakości zebranego plonu.
Wgłębna aplikacja nawozu mineralnego korzystnie wpłynęła na poziom plonowania soi oraz przyczyniła się do zwiększenia zawartości aminokwasów Met i Trp, a także P, K i Mg w nasionach. W porównaniu z powierzchniowym wysiewem nawozu stwierdzono jednak zmniejszenie zawartości Glu i Ala w nasionach. Nasiona soi zebrane z powierzchni, na którą wniesiono wyższą dawkę nawozu Polifoska®6 odznaczały się większą zawartością białka ogólnego i P. Z kolei więcej włókna, aminokwasów (z wyjątkiem Cys, Met i Trp), a także N, K i Mg zawierały nasiona soi w wariancie z niższą dawką nawożenia mineralnego.
Logarithmic Barrier Method Via Minorant Function for Linear Semidefinite Programming
Authors: Leulmi Assma
Published: February 2023

We propose in this study, a new logarithmic barrier approach to solve linear semidefinite programming problem. We are interested in computation of the direction by Newton’s method and of the displacement step using minorant functions instead of line search methods in order to reduce the computation cost.

Our new approach is even more beneficial than classical line search methods. This purpose is confirmed by some numerical simulations showing the e˙ectiveness of the algorithm developed in this work, which are presented in the last section of this paper.

Empirical Research on Investor Behavior in Pre-Listing and Post-Listing Periods - A Comparative Analysis Between the Regulated Market and the MTF Aero Administered by the Bucharest Stock Exchange
Authors: Spătăcean Ioan Ovidiu , Todoran Dorinel-Vasile
Published: February 2023

Investor behavior around an initial public offering or private placement can make the difference between a successful investment or a potential loss. Through the present research, the correlation of investors’ behavior with the possible discount of the share granted in the case of initial offers was sought. The large number of companies listed on the Bucharest Stock Exchange in 2021(23) compared to 2020(3) denotes the fact that the SARS-COV2 virus was a certain catalyst of interest for investors and companies to enter the Romanian capital market. From another point of view, we observe a strong orientation of companies towards MTF AeRO. Out of the total of 26 analyzed companies, only 3 of them chose the regulated market for trading
Multiple exposure to thunderstorm sound in Nile tilapia (Oreochromis niloticus): physiological response and stress recovery
Authors: Kusku Halit , Yigit Murat , Yilmaz Sevdan , Yigit Ümüt , Ergün Sebahattin
Published: February 2023

The present study investigated the impacts of multiple thunderstorm-sound exposures on growth and respiratory parameters in Nile tilapia (Oreochromis niloticus) in order to evaluate the acoustic stress response. Thunderstorm-sound exposure for 3 hours triggered respiration speed with an alarm reflex and rapid elevation of opercula beat rate (OBR) and pectoral wing rate (PWR), which increased two-fold over the control with no sound treatment, and peaked (OBR, 71.33±5.86 beat/min; PWR, 75.00±3.61 beat/min) in 10 hours after initiation of sound. Thereafter, respiration rates declined over the following days and returned to near-initial levels (45.33±4.04 beat/min OBR and 43.00±1.00 beat/min PWR) by day 3, an indication that fish recovered from thunderstorm-sound stress after 3 days of exposure. However, the same reaction course was observed each time of multiple sound exposures, repeated 20 times in a row with 4-day intervals, underlining that fish could not attune to repeated thunderstorm sound. Reduced voluntary feed intake as a result of anxiety and appetite loss was recorded in fish exposed to multiple thunderstorm sound, resulting in 50% less growth compared to those without sound treatment by the end of the 80-day experimentation. Therefore, it is advisable to monitor fish behavior during the 3-day stress period after a thunderstorm event in order to prevent waste from excess feeding, that in turn may contribute environment-friendly aquaculture for the future and sustainability of the oceans.

Commercial broilers have a short production cycle and a high requirement for energy (3000 kcal/kg in starter phase and 3200 kcal/kg in finisher phase). Therefore, the need to add energy rich lipids to their diet is inevitable. Digestibility of fat depends on its multiple properties: chain length, the composition of fatty acids, ratio of saturated/unsaturated fatty acids and free fatty acids. The high cost of vegetable oils and less availability due to their consumption in human diet are the main reasons for searching for cheaper alternative fat sources. Animal oils like poultry and fish oil are the by-product of rendering plants and after refining, they are used in poultry diets as an energy source. Due to presence of impurities and free fatty acids, the digestibility of animal fat is lower. There is a limited amount of bile acids and lipase available during early age and when birds are reared on high energy diet (finisher phase). Supplementation of emulsifier or lipase in broilers’ diet increase fat utilisation. Emulsifiers increase fat digestibility by increasing active surface area of lipid droplets. Lysolecithin and lysophospholipids are produced from hydrolyses of lecithin and phospholipids by phopholipase A2. The bile acids are mainly composed of cholic acid, hyodeoxycholic acid and chenodeoxycholic acid and have strong emulsification properties. Triacylglyceryl acylase (lipase) is an enzyme involved in catalysis and the hydrolysis of lipids. It can be concluded that use of emulsifier and lipase in broiler diet improves growth performance, nutrient digestibility and intestinal histology in broilers.

Authors: Vlčko Tomáš , Bokwa Krzysztof , Jarosz Iwo , Szymkowiak Andrzej , Golian Jozef , Antoniak Marcin , Kulawik Piotr
Published: February 2023

A growing interest has been noted among both industry operatives and consumers in cell-based meat (CBM), as visible in the increasing investment into this technology by major food industry corporations. However, in almost all countries worldwide, there is a lack of clear legislation with regard to the labeling of such products. The aim of the article is to collect and review current legal regulations concerning the international approval and labeling of these types of products. In the manuscript, we review and analyze the legal situation of CBM and its labeling in countries from 4 different continents (EU members, the UK, the USA, Canada, Australia and New Zealand, Japan, Singapore and Israel). Aside from Singapore, no other country has approved CBM for placement on the market. The US has reached an agreement and established regulatory frameworks on CBM matters, where both the USDA and the FDA will be the control institutions. Within the European Union, CBM products will be evaluated under the Novel Food Regulation. The most anticipated process in other countries is the evaluation of CBM under the legislation on novel foods and subsequent amendments. Since local laws are still being developed, special care should be taken by the policymakers to avoid implementing local laws which could cause a negative approach to the technology by the consumers.

It has been hypothesized that mutations in the ghrelin gene in pigs may play a similar role as in humans and may be associated with obesity. The aim of study was to analyse the polymorphisms of ghrelin gene and to evaluate its effect on pigs’ carcass traits. The effect of c.-93A>G, 4428T>C and g.4486C>T polymorphisms at the ghrelin gene on slaughter performance was analysed in 346 gilts represented by three breeds (Polish Landrace, Duroc, Pietrain). Animals were fattened from 30 to 100 (±2.5) kg body weight. After slaughter, the carcasses were chilled for 24 hours (4ºC), weighed and the right half-carcasses were dissected and evaluated. A number of data were obtained including: meat weight in primary cuts, weight of ham, backfat thickness and carcass yield. From breeding and production point of view, the favourable results were obtained for pigs with the GG genotype at the c.-93A>G locus, characterized by better carcass results than those with the AA genotype, e.g. higher ham weight and lower average backfat thickness. In pigs with the TT genotype at the g.4428T>C locus, we found lower mean backfat thickness than in pigs with the CC genotype.

Published: February 2023

The current work aimed to find substitutes for antibiotics because of the side effects of antibacterial agents and the expansion of bacterial resistance to these agents. The scope of this study was to evaluate the antibacterial activity of gold and silver nanoparticles (AuNPs and AgNPs) against selected animal pathogens (Staphylococcus aureus, Klebsiella pneumonia, Streptococcus pneumoniae, Escherichia coli, Bacillus abortus and Mycobacterium bovis). The synthesized nanoparticles were distinguished by scanning electron microscopy (SEM) analysis and tested for antibacterial activity with the broth microdilution method, well diffusion assay, and minimum bactericidal concentration procedure. Results showed that both AuNPs and AgNPs displayed good antibacterial activity against all tested bacteria. The strongest antibacterial action of AgNPS (18 mm) was against E. coli. AuNPs displayed good antibacterial activity against S. aureus and B. bovis with a suppression area of 14 mm. Therefore, it is suggested that AgNPs and AuNPs could be effectively used against animal pathogens and may contribute to reducing antibiotic resistance. However, there is a need for further research on the in vivo toxicity and mechanisms of action of AuNPs and AgNPs.
Exploring DNA methylation data for diagnostic classification of Diffuse large B-cell lymphoma in Dogs
Authors: Giwa Abdulazeez , Adu Oluwaseun
Published: February 2023

Diffuse large B-cell lymphoma (DLBCL) is a common B-lymphocyte tumor in dogs, making up 60-70% of cases. We assessed the utility of DNA methylation data for the diagnostic classification of DLBCL in dogs. We also assessed the utility of the classification features identified in cDLBCL for diagnostic classification of DLBCL in humans. The GSE94913 cDLBCL DNA methylation dataset from the Gene Expression Omnibus (GEO) was used for analysis. Differential methylation analysis was performed between the 37 cDLBCL and seven control lymph node samples in the dataset. 1701 differentially methylated probes were identified between the cDLBCL and control lymph nodes groups. Applying recursive feature elimination on the 1701 significant probes, 20 probes were selected for machine learning classification tasks. The methylation values of these 20 probes were used to build an SVM model and create the training and testing set. 100% of the test samples were accurately classified by the SVM model. The diagnostic classification utility of the identified differentially methylated CpGs/CDS was also assessed in humans using the GSE28094 human DLBCL dataset. 95% of 98 DLBCL and leukocyte samples obtained from this dataset was correctly classified using clustering techniques on 11 CpG sites of 5 genes (ERBB4, IGF2, PGF, PITX2, TJP1). The utility of DNA methylation data for the diagnostic classification of DLBCL in dogs is demonstrated. Further exploration of this data type for potential biomarker discovery in cDLBCL is necessary.

Microsporidia are enteric intracellular pathogens infecting animals and humans. It causes life-threatening diarrhoea in humans. Microsporidia species have been isolated from several domestic and wild animals, however, data on microsporidia infection in animals in Nigeria is still very scanty. This study was conducted to clarify and improve our knowledge of the possibility of the zoonotic origin of Enterocytozoon species in the environment. Two hundred and fifty (250) animal faecal samples from various farm animals were examined for their frequency of microsporidia spores using Weber’s chromotrope stain and Indirect Fluorescence Antibody Test (IFAT). Enterocytozoon bienuesi were detected in 6 (24.0%) turkeys, 2 (8.0 %) goats, 3(12.0 %) cattle, and 4(16.0%) rams. No reactivity was detected with other species of microsporidia by IFAT. This study confirms the presence of E. bienuesi in the animals examined and shows that animals can be a significant source of zoonotic transmission in the environment.
Spiraea decumbens Koch subsp. tomentosa (Poech) Dostál, novelty for the flora of Slovenia and the Dinaric Alps
Authors: Dakskobler Igor
Published: February 2023

In Govci under Mt. Poldanovec above the Trebuša Valley we found a new locality of southeastern-Alpine (Alpic) endemic Spiraea decumbens subsp. tomentosa, which is new to the flora of Slovenia and the Dinaric Alps. Its closest known localities are in the western Julian Prealps in Northeastern Italy. A small population of several ten shrublets occurs at elevations of about 570 m in shady, almost vertical dolomite rocks, in a stand of the endemic association Phyteumato columnae-Primuletum carniolicae. Despite a very small population we assume there are other localities in this area, where numerous gorges are very difficult to acces and have therefore not yet been sufficiently studied.

Authors: Peregrym Mykyta , Koopman Jacob
Published: February 2023

There are 96 species of the genus Carex (Cyperaceae) known in the flora of Ukraine, but so far there are no data about its hybrids for the country yet. However, the first one, C. × takhtadjanii [C. diluta × C. distans], was discovered in Starobilsk town (Luhansk region) during a field investigation in 2021. Detailed information about this floristic finding with the description of morphological characters of this hybrid and its habitat is given. Also a map with known locations of C. × takhtadjanii around the world is compiled, as well as the main morphological differences between this hybrid and its parental species are reported.

The Euphorbia resinifera is melliferous and medicinal plant and one of the endemic species of Moroccan Atlas Mountains. It is very well known for its honey of high nutritional and therapeutic quality. The objective of our study is to characterize and evaluate the phenotypic variation of this spontaneous species. Seventeen qualitative and quantitative morphological characters related to the bush, stem, spine, flower, and fruit of the plant were used to assess the morphological variability of twelve natural populations collected from its geographical range in Morocco. The results of the analysis of variance showed significant differences between the studied populations for the most examined traits reflecting the existence of a high phenotypic variability within this species. The principal component analysis showed that E. resinifera populations were clustered in three distinct groups not related to mountain range type. The results highlight a high phenotypic diversity within studied populations of this species in Morocco. This work aims to study the phenotypic variability of E. resinifera to delineate conservation strategies and also to establish forms of rational economic exploitation.

Published: February 2023

Introduction

Canine periodontitis results among other factors from a disturbed balance of dental plaque microflora and an inadequate host inflammatory response to a stimulus. This investigation sought to identify microorganisms associated with canine periodontitis.

Material and Methods

Microbiological analysis was undertaken of gingival pockets in an experimental group of 36 dogs with periodontal diseases. Swabs were collected with the use of Pet Test (MIP Pharma, Berlin, Germany) from patients with gingival pockets deeper than 5 mm. Samples were aggregated and placed in separate shipping containers with the Pet Test kit.

Results

Identification was made of the most common microorganisms, e.g. Porphyromonas gingivalis, Treponema denticola and Prevotella intermedia. The red complex constituted the largest proportion of all analysed organisms (84.26%). Capnocytophaga gingivalis was isolated from 33 dogs, Peptostreptococcus micros from 32 dogs, Fusobacterium nucleatum from 29 animals and P. intermedia from 20.

Conclusion

The highest percentage of pathogens was supplied by P. gingivalis (61%). It is thought that dogs acquire them by means of cross-species transmission. The inter-study variability of results may depend not only on the method of periopathogen detection, but also on environmental factors, host immune status or genetic background. Depending on the state of periodontal disease, patients show varied microbiological profiles of the gingival pockets.

This review summarizes the history, function, application, and achievement of the RheumCloud App as a novel smartphone application. This App reflects the development of the Chinese Rheumatism Data Center (CRDC), which provides not only a technical platform for the database and registry of rheumatic diseases (RDs) in China, but also a close tie between Chinese rheumatologists and patients with RDs. Throughout the past decade, CRDC has successfully built the world’s largest nationwide database for RDs. A total of 2074 tertiary referral centers consisting of 8051 rheumatologists participated in the registry. RheumCloud App, which is representative of the success of CRDC, has played a central role in supporting patient cohort registration, biosample collection, and patient education. Based on the data of the Rhuem-Cloud App, three national key research projects have been funded and a series of research papers have been published.
Echo Answers in Chinese
Authors: Wei Ting-Chi
Published: February 2023

This paper studies echo answers to yes-no questions in Chinese with respect to their distributions, derivations, and typological patterns. We reconsider Simpson’s (2015) verb-raising analyses of verb echo answers (VEAs), finding that his analysis is inspiring in describing the significant properties of VEAs but that he has not discussed issues pertinent to the role of le in VEAs, adverbial echo answers, and multiple verb echo answers. This paper proposes that the derivation of short echo answers in Chinese is two-fold: the verb echo answer involves V-to-v movement, pro-drop, and VP-deletion; and the adverbial short answer involves focus movement and TP deletion. The aspectual markers, the post-verbal le1 denoting perfective and the sentence-final le2 encoding a change of state in Chinese, play a crucial role in determining the grammaticality of certain verb-echo answers via aspectual anchoring. This analysis avoids analytical problems posed by V-to-C (domain) (Holmberg 2016; Simpson 2015, etc.). Evidence from information focus and negative scope reversal supports this two-track analysis of echo answers in Chinese. Finally, we conclude that typologically, Chinese, a language using verb-echo answers, is close to Vietnamese and Finnish in allowing adverbial short answers and akin to Thai and Finnish in allowing multiple verb echo answers.
Oral health-related salutogenic factors: reviewing factors promoting oral health in older people and exploring dental professionals' perspective
Authors:   , Shmarina Elena
Published: February 2023

The overarching aims of this thesis were to study oral health-related salutogenic factors among older people and explore dental professionals’ perceptions of their role in the practice of oral health promotion.Study I was an integrative review describing salutogenic factors reportedly associated with oral health and oral health-related quality of life in older people. A framework for identifying salutogenic factors, combining two theories of health, was developed. 58 papers were included in the review and 77 salutogenic factors were identified. However, there is a lack of studies with specific reference to salutogenic factors among older people. Study II was a cross-sectional study based on data for patients 60 years or older derived from a previous population-based epidemiological study. Several significant associations between outcome variables and salutogenic factors were identified. Of those, 13 previously unreported salutogenic factors could be added to the framework developed in Study I. Studies III and IV were qualitative interview studies using in-depth interviewsfor data collection and qualitative content analysis methodology for data analysis. Study III focused on exploring salutogenic factors related to oral health in twelve orally healthy patients 75 years or older. The findings highlighted the importance of patients’ internal resources, dental professionals, family, and society in supporting and reinforcing lifelong oral health. Study IV focused on exploring dental professionals’ perceptions of their role in the practice of oral health promotion and included eleven dentists and dental hygienists. The participants perceived promotion of oral health to be an important aspect of their professional role. They aspired to patient participation in the decision-making process and educational activities, as well as practicing and evaluating skills development. In conclusion, there is a need for consistency in definition of outcomes measures and hypothesis-driven research within salutogenic research in oral health field. The large number of salutogenic factors found supporting oral health among older people indicates the complexity of salutogenesis and the need for robust analyzing tools. Combining two theories of health was useful for exploring salutogenic factors related to oral health and for providing a plain overview of areas lacking knowledge, which in turn can facilitate the generation of hypotheses and therefore relevant salutogenic research.This combination could contribute to a more balanced image of factors influencing oral health, including dental professionals’ roles, and help identify critical next steps in determining priorities and allocating resources promoting good oral health in individuals and populations. Moreover, oral health-related salutogenic factors identified in the qualitative studies; i.e., categories, merit further exploration in quantitative research.

Published: February 2023

La gestión del agua en el valle de la Sabana y sus cuencas aledañas en el área periurbana de la ciudad de Acapulco, se ha realizado sin considerar las condiciones socio-ambientales que subyacen entre la pobreza, la marginación y su interacción con los recursos naturales por lo que, continúan persistiendo la construcción de riesgos por déficit en los servicios de agua potable y su saneamiento en un contexto de vulnerabilidad socio-ambiental de sus habitantes. El objetivo fue determinar los factores preponderantes que inciden en la vulnerabilidad socio-ambiental ante la falta de servicios de agua potable y saneamiento en la Micro-Cuenca Arroyo Las Cruces. Se aplicó el enfoque sistémico y de cuenca, así como la técnica multivariante Análisis de Correspondencias Múltiples (ACM). Con base al análisis relacional de los resultados del ACM, los factores que determinan la vulnerabilidad socio-ambiental son la carencia de servicios públicos, dependencia de la población por recursos naturales contaminados y baja participación comunitaria para hacer frente a sus problemas comunitarios ante la prevalencia de conflictos. La relación sistémica entre estos factores limita las capacidades socio-organizativas lo que podría incidir en los procesos participativos para la gestión del agua bajo un esquema local de gobernanza que contribuya en asegurar el abastecimiento de agua y saneamiento en áreas marginales en este espacio periurbano.
