Experts have recently highlighted a decline in food production, especially potato production when combined with climate change. With fluctuations in rainfall, planting time greatly influences potato production. To stabilize it, we can adjust the potato planting time by analyzing climate changes and land changes. So that the use of technology for forecasting planting times that is suitable for potatoes can be done to create sustainable potato production. The study area for this research is Batu City. This is because Batu City is one of the productive potato producing areas. Data acquisition was carried out using secondary data from two government agencies, namely the Water Services Agency and the Meteorology, Climatology and Geophysics Agency. Table data obtained on monthly averages was processed using open source software, namely QGIS 2.14 (essen). Through research, we found a method to predict the appropriate potato planting time based on rainfall data. January to April is the recommended time to plant potatoes. Meanwhile, from June to October it is not recommended to plant potatoes.

Energy and its changes are one of the materials taught in primary education. Learning about energy and its changes is very much related to everyday life so it is very important to master. The learning outcomes of energy and change are still quite low. The low-energy learning outcomes and changes are caused by the use of methods that do not follow the characteristics of the research material. Essay tests are used to determine understanding or learning outcomes based on the material students learn after doing activities. This study was conducted to determine the implementation of experimental methods on energy and change learning. Action Research was conducted on 21 grade IV students as a research sample. The action is carried out three times to obtain maximum results. Action results using the experimental method showed that there was a gradual increase in learning outcomes from the first, second, and third cycles

Lump-Sum Payment for Purchasing Residential Premises as an Additional State Guarantee for State Civil Servants of the Russian Federation: Exercise of Right
Authors: Bashurov V. B.
Published: March 2024

The subject of the study is the norms of the legislation of the Russian Federation on the state civil service of the Russian Federation. These norms provide additional guarantees for state civil servants of the Russian Federation for lump-sum subsidy aimed at acquiring accommodation. The purpose of the study is to consider the legal significance of a lump-sum subsidy for buying accommodation, to identify the conditions for the right to this subsidy, to determine whether it is mandatory or optional for the constituent entities of the Russian Federation to exercise their powers to provide employees of the subject of the Russian Federation with a lump-sum subsidy for the accommodation, to propose amendments to the legislation. The methodology of the study are such scientific methods as formal legal, structural functional approaches, comparison, research and analysis of studies and regulations. The study uses scientific research in the field of social security law and economic sciences. As a result of the study, the paper substantiates that a lump-sum subsidy for accommodation is provided in order to ensure the social security of civil servants of the Russian Federation. The right to this payment should be assigned only to those civil servants of the Russian Federation who need it and who, without the state support, are not able to change their financial situation and acquire accommodation. The paper proves the need for codifying the conditions for the right to this lump-sum subsidy. Using the analysis of federal and regional legislation that defines the powers of public law entities in the sphere under consideration, the paper proves the obligatory adoption of legal acts aimed at exercising the right of a civil servant of the Russian Federation to a lump-sum subsidy for the accommodation, regardless of the finances of the relevant budget. In order to have a unified legal regulation of the relations under consideration, the study substantiates the need to combine basic and additional state guarantees for civil servants of the Russian Federation, and presents specific proposals for changing federal legislation.

Authors: Vural Alper , Karaçam Cemil
Published: March 2024

Consider a set of vectors, L, which consists of vectors whose coordinates are 0 or 1. We find explicit formulas that counts the number of lattice paths from origin to (a,b,c,d) for using vectors in {(1,0,0,0),(0,1,0,0),(0,0,1,0),(0,0,0,1)} ∪ L for various choices of L. In some cases we also give the recursive formulas for the same problem. Next we determine the minimum number of vectors that must be used to reach (a,b,c,d), also called the minimum distance problem, for different sets of vectors.

Authors: Yulianti Lyra , Welyyanti Des , Yanita Yanita , Fajri Muhammad Rafif , Saputro Suhadi Wido
Published: March 2024

The metric dimension of an arbitrary connected graph G, denoted by dim(G), is the minimum cardinality of the resolving set W of G. An ordered set W = {w1, w2,..., wk} is a resolving set of G if for all two different vertices in G, their metric representations are different with respect to W. The metric representation of a vertex v with respect to W is defined as k-tuple r(v|W) = (d(v,w1), d(v,w2),..., d(v,wk)), where d(v,wj) is the distance between v and wj for 1 ≤ j ≤ k. The Buckminsterfullerene graph is a 3-reguler graph on 60 vertices containing some cycles C5 and C6. Let B60t denotes the tth  B60 for 1 ≤ t ≤ m and m ≥ 2. Let vt be a terminal vertex for each B60t. The Buckminsterfullerene-net, denoted by H:=Amal{B60t,v| 1 ≤ t ≤ m; m ≥ 2} is a graph constructed from the identification of all terminal vertices vt, for 1 ≤ t ≤ m and m ≥ 2, into a new vertex, denoted by v. This paper will determine the metric dimension of the Buckminsterfullerene-net graph H.

Authors:   Ph.D., Assistant Professor, Department of Applied English, Shu-Zen Junior College of Medicine and Management, Kaohsiung, Taiwan, Liang Shu-Chuan
Published: March 2024

The main goal of this study is to evaluate the effectiveness of the Quizlet flashcard app for learning English dental terminology. 100 dental-technology students from a five-year junior college in southern Taiwan participated in this study. Participants had access to Quizlet for learning281 dental terms. By using a quasi-experimental research design, data were collected from vocabulary quizzes and a questionnaire. Vocabulary quiz results were compared to measure the effectiveness of Quizlet’s assistance. The questionnaire was distributed after the use of Quizlet to evaluate satisfactory features of the software. Preliminary research findings have shown a positive correlation between frequency of Quizlet use and the acquisition of dental vocabulary, at a significance level of p < .001~.005. In addition, the participants gave positive feedback on Quizlet’s functions with mean scores ranging from 4.71~5.0 (on a 6-point scale). Unexpectedly, the perceived benefits of using Quizlet did not result in satisfactory test scores because the students did not use it extensively. Future research can focus on the correlation between students' perceptions of educational apps and their eagerness to use them.
Elementary structures of public policies
Authors: Di Giovanni Geraldo
Published: March 2024

This article proposes an integrated approach to analyzing public policies. Considering that the historical observation of different types of public policy has shown the occurrence of common aspects in all of them, the analysis proposal assumes that these are structured and recurring relationships. It also assumes that it is possible to grasp the primary elements that make up these relationships by verifying the degree of organicity, coherence and consistency that is established between them. The “elementary structures” are examined in four dimensions: formal, substantive, material and symbolic. The concept of public policy is evolving. Likewise, the analysis of its elementary structures must reflect the changes that have taken place over time.
Key factors contributing to postgraduate students’ success: Making a case for Coronavirus-19 and beyond
Authors: Sosibo L
Published: March 2024

Coronavirus-19 (COVID-19) pandemic caused major disruptions to the education sector, with detrimental effects on the supervision of postgraduate students and their success. Higher education institutions (HEIs) shut down to observe COVID-19 protocols and minimise the spread of the virus. University closures forced postgraduate-supervision processes to be conducted online, resulting in students experiencing many challenges, such as, loss of social networks and social interaction, lack of access to university computer laboratories and software, inability to collect face-to-face data, and wellness and mental problems. Whereas abundant research exists on COVID-19, little is known about factors that contributed to postgraduate students’ success during the COVID-19 pandemic. This qualitative case study reports on the factors that promoted student success during the COVID-19 pandemic, from the perspective of 23 postgraduate students. Data were collected through an online questionnaire and analysed through colour-coding and thematic categorisation. Results revealed that both students and supervisors contributed to the success of postgraduate students. They also showed that some students possessed certain attributes that enhanced their success, as well as that some postgraduate supervisors employed novel approaches to students’ supervision that promoted students’ success. This article encourages HEIs to leverage these factors to promote postgraduate student success beyond the COVID-19 pandemic.
A study of doctoral time-to-degree in selected disciplines at South African public universities
Authors: van Lill M.H.
Published: March 2024

Scholarship on doctoral success highlights differences in timely degree attainment between disciplines. However, research on doctoral education in South Africa is limited to identifying general factors that affect the successful completion of a doctoral degree with very little reference to differences across disciplines. This study’s objective is to compare time-to-degree, as the number of years between a doctoral student’s commencement year and graduation year, across selected disciplines as well as to identify factors, above and beyond that of disciplinary field, which are explanatory of shorter time-to-degree. The study investigates the role of selected student demographics (such as commencement age, gender, race, and nationality), institutional (type of higher education institution), and situational factors (such as part-time or full-time enrolment) in predicting doctoral time-to-degree. Results of multiple linear regression models indicate that mode of enrolment is the strongest predictor of completion time with part-time students recording a statistically significantly longer time-to-degree when compared to full-time students. A student’s discipline, nationality, and institution are also identified as statistically significant predictors of time-to-degree while gender, race, and age are not. However, the interaction between commencement age and enrolment mode is indicated to be a strong predictor of doctoral completion time. Although shorter completion times can be considered an indicator of efficiency at doctoral level, it is imperative to consider wider contextual factors in thinking about this issue.
Promoting student success in online post-graduate studies at a South African University: The role of professional and administrative support
Authors: Johannes E , Lalendle L
Published: March 2024

Post-graduate online students studying in cohorts are expected to collaborate effectively with their peers and instructors in the virtual environment and are presumed to have the necessary skills needed for self-directed online learning. However, studies have shown that the low retention and success rates in online learning could be attributed to individual students experiencing a sense of isolation in a community of online students. Providing various non-academic support is as crucial for ensuring success as academic support services. More importantly, the support should acknowledge and address the unique set of skills, experiences, and expectations of the individual student in the community of online learners. This study aimed to ascertain whether professional and administrative student support that focused on the individual needs of the post-graduate student promotes retention and success in online studies. A qualitative case study at a business school at a South African higher education institution evaluated the professional and administrative support types, range and timing in promoting success in online post-graduate studies. This included the content analysis of key documents such as the self-evaluation report and the survey report on evaluation, impact and lifelong learning of a post-graduate qualification, followed by a focus-group session to ascertain staff perceptions of the professional and administrative services and resources in promoting success in online post-graduate studies. Using Simpson’s Proactive Motivational Support model (PaMS) as a lens, the study revealed a lack of motivational aspects of student support for online post-graduate students. Furthermore, the results affirmed the presumption of post-graduate students as a homogenous group prepared to succeed in online learning communities. Moreover, that limited provision was made to support online post-graduate students from remote areas and for those with disabilities. The study concludes that a more personalised approach to student support will motivate post-graduate students to become successful self-directed students in a community of online learners. Moreover, a focused school, college and institutional approach and an integrated inter- and intra-institutional collaboration are needed to enhance self-directed learning, foster a sense of belonging, and promote success in online post-graduate studies.

Numerical models of bone remodelling have traditionally been used to simulate bone loss in postmenopausal women and the response to drug treatments. These models simulate the menopausal estrogen decline by altering certain signalling pathways. However, they overlook the simultaneous effect that ageing can have on bone cells function and thus on bone loss. Considering ageing and estrogen decline together is important for designing osteoporosis treatments that can counteract one of the two factors.A previously developed bone remodelling model was adapted to consider the effect of ageing through: (1) decreased TGF-beta content within bone matrix; (2) increased sclerostin production by non-skeletal cells. Estrogen deficiency is simulated in three different ways: (a) increased RANKL expression; (b) decreased OPG production; (c) increased responsiveness of osteoclasts to RANKL. The effect of ageing was validated using clinical BMD data of vertebral trabecular bone from males. The joint effect of ageing and estrogen deficiency was validated using the corresponding clinical data in women.In ageing, the effect of increased sclerostin production is more important than the decrease in TGF-beta. The three mechanisms used to simulate the effect of estrogen deficiency yielded almost identical responses. The results show that early menopause leads to lower density in the fifth decade, but after the sixth decade density is almost independent of the age at menopause on average. Osteoporosis treatment with denosumab was also simulated, concluding that the treatment proves more necessary after 10 years since menopause or after age 60.

Pneumonia is an infection that affects one or both lungs and is caused by fungus, bacteria, or viruses while Malnutrition is defined as a dietary imbalance. Pneumonia and malnutrition are two different illnesses, however, they often coincide andcan have a substantial impact on child mortality in pneumonia-endemic regions.Considering their geographical proximity, there has been no mathematical analysisof their co-dynamics. To address this gap, we develop a deterministic pneumonia mathematical model that divides children into two groups: well-nourished andundernourished, to investigate the potential effect of malnutrition on pneumonia dynamics. The basic reproduction number of the proposed model is computed usingthe Next-Generation Matrix and both local and global stability of the disease-freeequilibrium is examined. Using the model parameters, the sensitivity analysis isperformed by using the Normalized forward sensitivity index to establish their effects on the basic reproduction number. Furthermore, Numerical simulations areprovided based on the model parameter values chosen. The results show that individuals who are malnourished have a higher chance of acquiring and dying frompneumonia than well-nourished individuals.
Experimental evidence of the molecular and macroscopic origins of circular dichroism in chiral metal-halide networks
Authors: Abhervé Alexandre
Published: March 2024

Clockwise or counter-clockwise spin coating? In the current hot research topic of chiral metal-halide semiconductors, several investigations have been undertaken in order to reveal their natural optical activity and have reported dissymmetry factors (gabs) for thin films of many hybrid compounds, usually without considering the macroscopic anisotropies inherent to solid-state samples. Yet, CD in the solid state can be strongly modulated by the co-existence of linear dichroism (LD) and linear birefringence (LB). Theoretical studies recently revealed the importance of such macroscopic interferences in the CD response of solid-state samples, often referred as symmetric (sLDLB) and antisymmetric (aLDLB) effects. Based on the newly synthesized one-dimensional lead-halide networks of formula (S/R-HP1A)PbBr3 and (S/R-HP1A)PbI3, an experimental method to accurately discriminate between CD, sLDLB and aLDLB in chiral metal-halide networks is here presented. The main experimental conditions influencing sLDLB and aLDLB amplitude are also highlighted, such as the concentration of the precursor solution and the spin-coating rotation direction, finally providing a complete experimental guide for the forthcoming chiroptical investigations of such important family of chiral hybrid materials.

Purpose
To analyze the evolution of uveitis diagnosis over a 10-year period, emphasizing the change in etiological diagnosis, and the factors associated with recurrences.
Design:
Retrospective chart review
Methods
A total of 15000 patients with uveitis presented to our tertiary care institute in North India between 1992 and 2023. Of these,123 patients completed 10-year follow-up and were included in the study. The data of patients was collected on an offline purpose-built uveitis registry portal:Ocular Autoimmune Systemic Inflammatory and Infectious Study(OASIS).
Results
The study included 123 patients (48.78% males; mean age:29.11 ± 15.22 years).The most common anatomical and etiological diagnosis at presentation were anterior (49/123,34.96%) and idiopathic(59/123,47.97%) uveitis respectively.At the end of 10 years, anterior uveitis remained the most common anatomical diagnosis(43/123,39.83%) while the most common etiological diagnosis was immune-mediated uveitis(50/123,40.65%). An etiological diagnosis could be established in 50.85%(30/59) of patients initially labelled as idiopathic.Tuberculous uveitis(39/44,88.63%) and Juvenile Idiopathic Arthritis associated uveitis (16/49,32.65%) were the commonest infectious and immune-mediated etiologies at the 10-year follow-up. Ninety-six(80.67%) patients experienced multiple episodes of ocular inflammation with a mean recurrences rate of 0.386 ± 0.24 recurrences/year. Anterior uveitis(p = 0.01), the change in etiological diagnosis after the first year(p = 0.03), positive HLA-B27 at baseline(p = 0.04), and the diagnosis of a systemic disease prior to onset of uveitis were associated with higher recurrences rates(p = 0.03).
Conclusion
Over 10-year of follow up, half of the uveitis diagnosis evolved from idiopathic to specific infectious or immune-mediated etiologies.Our results indicate that patients with a high recurrence rate may benefit from re-evaluation to find the definitive cause of uveitis.

Published: March 2024

Purpose
Potentially toxic metals can directly induce various adverse effects on reproductive organs or interrupt essential metals' physiological activities. Despite intensive efforts to reduce these metals in the environment, chronic and low-level exposure remains a public health problem. The present study aimed to investigate prenatal metal exposure, including arsenic (As), copper (Cu), lead (Pb), manganese (Mn), rubidium (Rb), selenium (Se), and zinc (Zn), effects on birth weight.
Methods
We collected 579 blood samples before the 16th week of gestation from apparently healthy women with singleton pregnancy in Iran and Japan. Blood metal concentrations were measured using inductively coupled plasma-mass spectrometry.
Results
Prenatal blood levels of As, Mn, Pb, and Zn were significantly higher, while Cu, Rb, and Se were significantly (p < 0.01) lower in Iranian participants than in Japanese. Adjusted linear regression analyses and Bayesian Kernel Machine Regression (BKMR) overall exposure-response functions showed inverse relationships between metals and birth weight.
Conclusion
The study findings, using data from geographically diverse countries, suggest prenatal blood metal exposure as a potential risk factor for lower birth weight. Therefore, women of reproductive age should minimize encountering to potentially toxic metals as much as possible.

Due to its sustainability, direct epoxidation of propylene into propylene oxide (PO) with molecular oxygen alone is believed to be an ideal route. Despite constant research efforts, numerous catalysts struggle with the trade-off between activity and selectivity, which typically results in poor PO yield. In this contribution, we presented an atomically distributed Cu catalyst that had precisely controlled Cu–N coordination numbers of 1:2, termed as Cu1–N2 SAC. In contrast to traditional Cu-based oxide catalysts, this catalyst features exclusive Cu–N coordination, replacing all Cu–O interactions. The synthesized Cu1–N2 SAC catalyst acquired an unprecedented PO formation rate of 5.9 mmolPO gcat–1 h–1 at 275 °C, outperforming any other catalysts reported so far. Sophisticated characterizations and density functional theory calculations revealed that the enhanced catalytic performance was attributed to exclusively forming the electrophilic oxygen species without nucleophilic oxygen species. As a result, these electrophilic oxygen species preferentially target the C=C bond instead of α C–H bond in propylene. These insights pave the way for a new avenue in the optimization of metal oxide catalysts through the precise manipulation of metal-nitrogen (M–N) coordination environments.
