Background:

GNAO1 is an emerging disorder characterized with hypotonia, developmental delay, epilepsy, and movement disorder, which can be potentially life threatening during acute exacerbation. In the USA, deep brain stimulation (DBS) has been licensed for treating children with chronic, treatment-resistant primary dystonia, who are 7 years old or older.

Case Description:

A 4-year-old girl diagnosed to have GNAO1-related dyskinesia and severe global developmental delay. She had severe dyskinesia precipitated by intercurrent infection, requiring prolonged intensive care for heavy sedation and related complications. Her dyskinesia improved dramatically after DBS implantation. Technical difficulties and precautions of DBS in preschool children were discussed.

Conclusion:

DBS should be considered early in the treatment of drug-resistant movement disorders in young children with GNAO1, especially after dyskinetic crisis, as they tend to recur. Presurgical counseling to parents and close monitoring of complications is also important in the process.
Unusual vascular anatomical variant leads to spontaneous hemorrhage in a cavum septum pellucidum in an adolescent: A case report and literature review
Authors: Salem Raghad Hany , Almubarak Abdulaziz Oqalaa , Hassounah Maher
Published: July 2022

Background:

Hemorrhagic lesions of the septum pellucidum are rare and usually occur in neonates. They can be due to a number of etiologies. Here, we report a rare case of adolescent nontraumatic septum pellucidum hemorrhage with a review of literature.

Case Description:

A 16-year-old girl presented with a 1-month history of gradual visual deterioration in the left eye, intermittent headache, and vomiting. Brain imaging showed hematoma located between the leaflets of the septum pellucidum with obstructive hydrocephalus. Transcallosal resection of interventricular mass was done. The patient was discharged with improved neurological symptoms; however, the left eye vision did not recover. Imaging demonstrated a unique anatomical variant in deep vascular structures.

Conclusion:

Cavum septum pellucidum hemorrhage is rare in adults. Many theories were constructed to explain its etiology. Bleeding due a vascular anatomical variant was not previously encountered. Understanding the embryological origin and anatomical details are important for proper clinical assessment and management of these patients.

Construction on permafrost in the harsh climatic conditions of the Arctic requires the use of both innovative materials and special engineering solutions. It is well known that the heat released during the operation of buildings can cause thawing of a frozen base, which leads to a loss of stability, irreversible deformations and the occurrence of accidents. One of the problem solutions is to maintain the base of the structure in a frozen state throughout the entire period of operation by using heat-insulating materials. The Arctic zone of Russia has inexhaustible local raw materials: opal-cristobalite and zeolite rocks for obtaining environmentally friendly heat-insulating material and providing the regional construction industry. Thus the authors propose a new technology of low-rise construction on permafrost foundations with the use of granulated foam-glass ceramic. They aim the study at the establishing the effect of a heat-insulating layer of granules on the temperature regime of permafrost foundation of low-rise building.
Comparative analysis of family values in Iranian and Russian cinema
Authors: Kosinova M. I. , Solgi T.
Published: July 2022

The purpose of this study is to analyze family values in Iranian and Russian cinema. The main objective of the study is to identify key trends related to the subject of the work based on the analysis of a number of Iranian and Russian films. As a result of the study, the authors found out that in the modern cinema of these countries, we often encounter negative trends indicating the disintegration of the traditional family. The source of these trends is the negative influence of the West, and in particular, Western cinema. The relevance of this topic is determined by the fact that the family as a social institution plays an important role in the society and culture of the country. In turn, cinema as a cultural tool has an impact on the process of forming the institution of the family. In this regard, a certain repertoire policy, regulated at the highest, state level, is able to influence a certain development of the institution of the family of a particular country. The article analyzes the activities of Russia and Iran at the state level aimed at protecting their culture. The main laws and draft laws that contribute (or will contribute) to the strengthening of traditional family values in the culture of Russia and Iran in general and cinema in particular are analyzed.

In the article, the authors investigate the problem of using unmanned aerial vehicles (drones) in company warehouses and consider their use as one of the ways to optimize the logistics business processes of companies. Technologies are considered, on the basis of which modern unmanned aerial vehicles, drone models of various companies, the main functionality of drone’s work. The authors high-light the strengths and weaknesses of unmanned aerial vehicles, key factors determining the success of the use of drones, and favorable conditions for their use in warehouses. The authors are considering the possibility of sharing drones and RFID technology. Barriers to the active introduction of drones into the logistics business processes of warehousing systems and requirements for warehouse complexes planning the use of unmanned aerial objects have been identified. Promising areas of application of technology in warehouse logistics are also considered: creation of anti-theft and fire protection systems, using drones to read CIS marks. The authors used data from analytical reports and data collected by the authors themselves, as well as empirical research methods.

Published: July 2022

Fluid flow is an inherent aspect of solution processing of conjugated polymers. Much of the existing work investigating the effect of flow has been phenomenological, lacking a direct and quantitative connection between the flow gradients and measurable quantities of the conformation or alignment of the conjugated polymers in solution. Furthermore, while aggregation of conjugated polymers in solution has been demonstrated to result in highly aligned thin-films, there are few studies that probe the interplay between the structures that form during aggregation and flow-induced alignment during processing. Here, we explore in detail the influence of flow type, solution aggregation, and concentration on the flow-induced alignment of conjugated polymers. We apply a microfluidic platform to systematically subject the conjugated polymer solution to large and controllable shear and extensional strain rates and use flow-induced retardance (birefringence) measurements to characterize the degree of alignment. By using flow-induced retardance in combination with small angle X-ray scattering (SAXS) and electron microscopy of freeze-dried solutions we are able to determine the solution state structure and clearly demonstrate the interplay between solution aggregation and fluid flow. We determine the overall relaxation time of the material and the strengths of shear and extensional flows required to align conjugated polymer aggregates. Furthermore, we find that although enhanced aggregation can facilitate flow-induced alignment, the type of aggregation and the presence of interparticle interactions at higher concentrations can diminish the effectiveness of flow. The results here demonstrate that there is a complex interplay between the conjugated polymer solution state and fluid flow and that simply increasing the conjugated polymer’s aggregation, concentration, or the strength of flow does not necessarily lead to better or more effective alignment in solution. A careful understanding of the synergy between these two aspects can help to establish design rules in solution processing for improving conjugated polymer film morphology.

The dopamine D4 receptor (D4R), a G protein-coupled receptor, is predominantly expressed in the prefrontal cortex in which it plays an important role in cognition, attention, and decision making. Studies have indicated D4R-selective ligands as promising therapeutic targets for the treatment of neuropsychiatric conditions such as substance use disorders (SUD). D4R ligands have been shown to alter cognition and behavior in animal models of drug addiction. A better understanding of D4R-mediated signaling is essential to treating D4R-associated disorders, including SUD. Despite its clinical importance, there are currently no FDA approved medications that target the D4R, and for example, treat cocaine use disorder. The present study focuses on the design of D4R-selective ligands based on the parental phenylpiperazine scaffold and pharmacokinetic analysis in rat and human liver microsomes, followed by in vivo pharmacokinetic and behavioral analysis. We identified several compounds with high binding affinity and D4R selectivity (Ki ≤ 6.87 nM and >91-fold vs. other D2-like receptors (D2R, D3R)) with diverse partial agonist and antagonist profiles. Based on the affinity profiles, 5f (CAB-01-019) was selected for an in vitro metabolic stability assay in rat and human liver microsomes which displayed an acceptable stability profile. Based on these results, we moved 5f forward into in vivo pharmacokinetic analysis in rats where it displayed excellent brain penetration with AUCbrain/plasma > 3. The full antagonist 5f (5, 15 and 30 mg/kg, i.p.) was tested in cocaine self-administration studies in rats, using a within-session multidosing procedure. 5f dose-dependently decreased the number of i.v. infusions obtained for three-unit doses of cocaine under a fixed ratio (FR) FR3 schedule of reinforcement, suggesting that the selected D4R antagonist reduced the rewarding effects of cocaine. Together, these results support the development of D4R-selective antagonists for SUDs and support 5f as a new probe for studying D4R-specific behaviors.
Adsorption, activation, and conversion of carbon dioxide on small copper-tin nanoclusters

Published: July 2022

Carbon dioxide (CO2) conversion to value-added chemicals is an attractive solution to reduce globally accelerating CO2 emissions. Among the non-precious and abundant metals tested so far, copper is one of the best CO2 catalysts capable of converting this molecule into more than thirty different hydrocarbons and alcohols. However, the selectivity for desired products is often too low. Here, we present a computational investigation of nanostructuring and Cu/Sn alloying effects on the activity and selectivity of CO2 conversion. We have employed density functional theory calculations to explore the possibility of using small Cu−Sn clusters, Cu4−nSnn (n = 0–4), to activate CO2 and convert it to carbon monoxide (CO) and formic acid (HCOOH). First, we have considered a detailed analysis of the structure, stability, and electronic properties of Cu4−nSnn clusters and their ability to absorb and activate CO2. Then, we report the kinetics of the gas phase CO2 direct dissociation on Cu4−nSnn to generate CO. We then discuss the mechanism of electrochemical CO2 reduction to CO and HCOOH on Cu4−nSnn clusters and the competition with the hydrogen evolution reaction. Based on our results, we conclude the Cu2Sn2 system has the highest potential as a stable and selective catalyst for the electrochemical CO2 conversion to CO. We found the Cu2Sn2 to suppress the competitive hydrogen evolution and be highly selective toward CO. This study demonstrates that Cu2Sn2 clusters are a potential candidate for the electrocatalytic conversion of the CO2 molecule. Moreover, it identifies insightful structure-property relationships for CO2 activation, highlighting the influence of composition on CO2 activation.
Chiral and Achiral Pendant-Bound Poly(biphenylylacetylene)s Bearing Amide and/or Carbamate Groups: One-Handed Helix Formations and Chiral Recognition Abilities
Authors: Ikai Tomoyuki , Okuda Shogo , Aizawa Motoki , Yashima Eiji
Published: July 2022

A series of cis-poly(biphenylylacetylene) (PBPA) derivatives bearing chiral and achiral pendant groups at the 4’-position of the biphenyl units through an amide (–NHCO–) or carbamate (–NHCOO–) linker were synthesized by polymerization of the corresponding biphenylylacetylene (BPA) monomers that can be readily prepared in one step from a novel amino-functionalized BPA. An excess one-handed helix induction in the PBPAs through covalent and noncovalent chiral interactions and their chiral recognition abilities when used as chiral stationary phases (CSPs) for high-performance liquid chromatography (HPLC) were investigated. PBPAs bearing optically-pure L-amino acid residues showed unique two-state helical conformational changes between the extended and contracted helices regulated by the solvent-mediated on/off switching of the intramolecular hydrogen-bonding formations between the pendants or at each pendant. The chiral recognition abilities of the helical PBPAs were significantly influenced by the kinds of the pendant L-amino acid residues. The preferred-handed contracted helical PBPA carrying an L-leucine derived pendant showed an excellent chiral resolving power toward various racemic compounds including axially and point chiral compounds and chiral metal complexes. The elution orders of some racemates were completely reversed when its helical conformation was changed to the extended helix. On the other hand, the trans-enriched nonhelical L-leucine-bound PBPA derived from its preferred-handed cis-helical PBPA and achiral pendant-bound cis-helical PBPAs induced by noncovalent chiral interactions and subsequent static memory of the helicity showed a poor and no chiral recognition, respectively.
Self-Experience and the Unconscious
Authors:   , Mathieson Darryl
Published: July 2022

In contemporary philosophy of mind and psychiatry, a phenomenon that attracts a lot of attention is a symptom of schizophrenia called thought insertion. People living with thought insertion claim that some of the thoughts they experience are not produced by them and are authored by someone else. To explain this phenomenon, philosophers and psychologists commonly distinguish between the sense of being the subject of one’s mental activity and the agent of that activity, arguing that thought insertion involves a breakdown in the sense of agency for some thoughts. Given this explanation, recent work has concluded that we normally have a substantial experience of ourselves as the thinker of our thoughts. In this thesis, I argue against this conclusion and the explanation of thought insertion underlying it. In the first chapter, I argue that cases of thought insertion do not entail self-experience. In the second chapter I raise two problems for the assumption that there is a sense of agency in thought in the first place. First, I argue that the phenomenology of thinking is passive, not active. Second, by appealing to some recent psychological research claiming that unconscious processes do the real work even in some paradigmatic examples of mental action, I argue this gives us further reasons to doubt that we normally have a sense of agency in thinking. Following this, in the third chapter I show that we can make better sense of thought insertion without appealing to a missing sense of agency in thinking, freeing us from having to assume its ordinary presence in normal subjects to explain thought insertion. I conclude in chapter four by discussing the implications of my arguments along with some directions for further research.

A Fuzzy Low-Dimensional Intersection Graph Representation Approach for Graph Compression and Anonymization. (c2021)
Authors:   ,   Lebanese American University, Yamout Youssef
Published: July 2022

The large amount of data represented as a network, or graph, sometimes exceeds the resources of a conventional computing device. In particular, links in a network consume a great portion of memory in comparison to the number of nodes. Even if the graph were to be completely stored on disk with the aid of virtual memory, I/O operations would require exhaustive computing power as opposed to queries that consult the main memory. However, rigorous edge storage is not always necessary to extract useful information and meaningful insights. In this context, we propose a fuzzy lowdimensional representation by mapping any given graph onto a k-dimensional space such that the distance between any two nodes determines their adjacency status. The proposed mapping utilizes an intersection graph representation where k-dimensional balls represent the nodes, and the likelihood of adjacency of two nodes is measured by whether the corresponding balls intersect. The objective is to answer adjacency queries as accurately as possible and to achieve an effective compression. We examine several heuristic algorithms in an attempt to achieve these two main objectives and conduct a thorough experimental analysis providing evidence of the effectiveness of our graph mapping approach. An additional perk of this work is the capability of completely hiding private information in networks.
The Impact of Electoral Engineering on Political Moderation and Stability in Divided Societies. (c2021)
Authors:   ,   Lebanese American University, Khoueiry Youssef
Published: July 2022

Politicization of ethnic identities is a major impediment to moderation in deeply divided societies. Two schools of thought dominate the literature on democracy in those types of societies, consociationalism and centripetalism. Consociationlaists support the philosophy of inclusion, power-sharing and mutual vetoes whereas, Centripetalists, promote the engineering of political institutions that encourage moderation through vote-pooling. Consequently, institutional engineering, more specifically electoral engineering is as a key tool to manage cleavages. This thesis aligns itself with centripetalism and evaluates Lebanon’s electoral law passed in 2017 against centripetalist core concepts, both in theory and using empirical case studies from the results of Lebanon’s 2018 elections. Theoretical evaluation of Lebanon’s electoral law showed that district formation, seats allocation and single preferential voting largely contradicts centripetalists concepts of bargaining, vote-pooling and moderate political discourses. Also, empirical results in Lebanon’s 2018 parliamentary elections showed that cross-confessional and cross sectarian votes of minority groups are very high in districts with established majorities and vice versa. However, these votes are found to be very minimal in districts where sectarian groups have an equal number of voters and parliamentary seats. Empirical results showed that the electoral law in Lebanon will encourage, with a high likelihood, the Lebanese voter to cast a sectarian vote in districts where sectarian groups have approximately equal number of voters and. The thesis concludes that should political moderation be promoted in Lebanon; proportional representation is be rectified by redefining district formation and seats allocation. Also, single preferential vote should be substituted by multiple preferential voting with ranking system.
THE MEDIATING IMPACT OF EMPLOYEE COMPANY IDENTIFICATION ON ETHICAL LEADERSHIP AND EMPLOYEE ENGAGEMENT. (c2021)
Authors:   ,   Lebanese American University, Bou Samra Waad
Published: July 2022

This study examines the relationship between ethical leadership and employee engagement in the presence of employee company identification, and whether perceived organizational politics have a moderating effect on the relationship between ethical leadership and employee company identification. To our knowledge, researches that studied these constructs and their relationships are scarce, and we expect to fill this gap in the literature. Drawing upon the social exchange, ethics, perceived organizational politics theories a conceptual model was developed and empirically tested. The study was conducted in Lebanon where questionnaires were collected from employees working in different industries. Data were analyzed using SPSS and Smart PLS. The results of our study provided support to the direct relationships and indicated that employee company identification fully mediated the relationship between ethical leadership and employee engagement. In addition, there was no evidence in this study that perceived organizational politics have any moderating impact on this relationship. The findings of this study provide theoretical and practical contributions.

Consumption of substances constitutes a health problem, especially among youth globally. Substances become a problem when they are consumed against professionals’ advice. Thus, this study analyses youth involvement in the consumption of psychotropic substances in Apapa Local Government, Lagos State. The study focused on the following objectives: to determine the predisposing factors to the harmful consumption of psychotropic substances; find out the types of psychotropic substances commonly consumed; examine the health problems associated with harmful consumption of psychotropic substances by the youths in Apapa Local Government Area of Lagos State. The Edwin Sutherland’s Differential Association theory was adopted as the theoretical framework for the subject matter. A qualitative narrative research design with the use of an in-depth interview guide was employed to gain insight and understanding about the experiences of thirty-two (32) psychotropic users, who were selected from across six wards of the study area through purposive and snowball sampling techniques. Findings revealed that lack of parental supervision; availability of drugs; and the need to gather extra energy to work for long hours, among others were largely responsible for harmful consumption of the substances. The various types of psychotropic substances consumed by youths in the study area include cannabis [popularly known as Indian hemp], alcohol, tramadol and codeine. The study further reveals that the youth involvement in harmful consumption of psychotropic substances had made them suffer health challenges, such as chronic cough, weight loss, tooth decay, bad breath, dry mouth and throat and headache. The study concludes that harmful consumption of psychotropic substances exposes youth to terminal illnesses and premature deaths. The study therefore recommends that treatment programs such as counselling, medication and other behavioural therapies should be readily available and be effective in attending to the multiple needs of addicted psychotropic users’ problems to mitigate their involvement in the consumption of the psychotropic substances.

Physics Course Content of University Physics Education Programme as Reference to Content Distribution of JUPEB and WAEC Syllabi
Authors: Badmus Olalekan T. , Bada Abiodun A. , Jita Loyiso C.
Published: July 2022

The evolution of curricula at any level of education remains relevant based on evolving developments, challenges, and policy direction of society. A university physics education programme has evolved over the years to accommodate, and in some instances, remediate the societal dynamics using the principles of physics. The training of physics teachers for post-basic or secondary education has changed over the years to accommodate solutions to various infractions. We examine the physics course content of a university physics education programme with a view to providing data on content distribution of both advanced and ordinary level physics syllabi. This study is qualitative research of the case study type which sampled the content of two syllabi and course content of a physics education programme. Content analysis was employed to analyse topics and subtopics among three documents. From the result, topics and subtopics were fractionalised to provide an overview of each of the three examined documents. The implication of this is that amendments can be systematically made to accommodate the newly introduce theme physics in technology. Thus, this study proffers a justifiable template for moderating textbooks to authors, bridging the gap between present and future additions and exposing areas of capacity building for physics teachers, among others.

Published: July 2022

Background

There is a paucity of data on community-based Clostridioides difficile infection (CDI) and how these compare with inpatient CDI.

Aim

To compare data on the populations with CDI in hospitals vs the community across 12 European countries.

Methods

For this point-prevalence study (July–November 2018), testing sites sent residual diagnostic material on sampling days to a coordinating laboratory for CDI testing and PCR ribotyping (n = 3,163). Information on whether CDI testing was requested at the original site was used to identify undiagnosed CDI. We used medical records to identify differences between healthcare settings in patient demographics and risk factors for detection of C. difficile with or without free toxin.

Results

The CDI positivity rate was 4.4% (country range: 0–16.2) in hospital samples, and 1.3% (country range: 0–2.2%) in community samples. The highest prevalence of toxinotype IIIb (027, 181 and 176) was seen in eastern European countries (56%; 43/77), the region with the lowest testing rate (58%; 164/281). Different predisposing risk factors were observed (use of broad-spectrum penicillins in the community (OR: 8.09 (1.9–35.6), p = 0.01); fluoroquinolones/cephalosporins in hospitals (OR: 2.2 (1.2–4.3), p = 0.01; OR: 2.0 (1.1–3.7), p = 0.02)). Half of community CDI cases were undetected because of absence of clinical suspicion, accounting for three times more undiagnosed adults in the community compared with hospitals (ca 111,000 vs 37,000 cases/year in Europe).

Conclusion

These findings support recommendations for improving diagnosis in patients presenting with diarrhoea in the community, to guide good practice to limit the spread of CDI.

As the COVID-19 pandemic began in early 2020, primary care influenza sentinel surveillance networks within the Influenza - Monitoring Vaccine Effectiveness in Europe (I-MOVE) consortium rapidly adapted to COVID-19 surveillance. This study maps system adaptations and lessons learned about aligning influenza and COVID-19 surveillance following ECDC / WHO/Europe recommendations and preparing for other diseases possibly emerging in the future. Using a qualitative approach, we describe the adaptations of seven sentinel sites in five European Union countries and the United Kingdom during the first pandemic phase (March–September 2020). Adaptations to sentinel systems were substantial (2/7 sites), moderate (2/7) or minor (3/7 sites). Most adaptations encompassed patient referral and sample collection pathways, laboratory testing and data collection. Strengths included established networks of primary care providers, highly qualified testing laboratories and stakeholder commitments. One challenge was the decreasing number of samples due to altered patient pathways. Lessons learned included flexibility establishing new routines and new laboratory testing. To enable simultaneous sentinel surveillance of influenza and COVID-19, experiences of the sentinel sites and testing infrastructure should be considered. The contradicting aims of rapid case finding and contact tracing, which are needed for control during a pandemic and regular surveillance, should be carefully balanced.
A human in the history of family: the crisis of identity in the novel “OST” (“Moroz’s Village”) by Ulas Samchuk
Authors: Pidburtna Diana
Published: July 2022

Colonial and postcolonial literature is essentially different from the literature of the colonizing states, in particular, this is manifested in the aspect of self-identification of characters. However, in this study, we are dealing with emigrant literature, which is a qualitatively different product that has absorbed the features of colonized and at the same time decolonized consciousness. This was reflected in the characters in the novels of émigré writers. The aim of the research is to analyze the peculiarities of the self-determination of characters in Ulas Samchuk’s novel “OST” (“Moroz’s Village”). The subject is the national identity of the characters, and its social conditionality. The study used such general scientific methods as analysis and synthesis, as well as the actual philological — aspect, image analysis, and historical and literary methods.

The focus was on national identity, the connection between generations and memory, tradition, and its preservation or rejection. The relevance of the study is due to a certain shift in perspective, and therefore considered aspects that scientists who have studied this problem, considered in part or bypassed. This is, in particular, the connection between the family and social identity of the Moroz family, the problem of memory and forgetting or separating oneself from the family; traced dynamics of self-awareness: the position of the characters throughout the novel is constant or variable. The novelty of the study connected with a deeper immersion in the social context of the struggle of 1917–1919 in the Cherkasy region, depicted by a writer who could afford to write in an uncensored environment and describe events without adhering to party doctrine. As a result, we found that a person’s self-determination depends entirely on society, but the environment around him is more important in adulthood than the family circle but provided that he rejected or did not preserve family memory, and illustrated this on the material of the novel “OST” (“Moroz’s Village”). The prospect of further research is to apply the chosen approach to the works of various writers of the past and present, which will see the formation and development of identities of characters under the influence of socio-political situations.

El objetivo de este artículo es presentar el discurso de las imágenes donde se encuentra retratado uno de los gobernantes más importantes de la dinastía Kaanuʔl del Clásico Tardío: Yuhknoʔm Yihch’aak K’ahk’, mejor conocido actualmente como Garra de Jaguar, quien gobernó en Calakmul entre los años 686 y 695, y murió en 697. Los ejemplos de sus retratos se encuentran en una estela, tres paneles de juego de pelota y una vasija, y tienen detrás un discurso que legitima e inmortaliza a este gobernante. Se considerará el texto que acompaña cada retrato para confirmar que es el gobernante en cuestión, y se argumentará su posible referencia si no existe un jeroglífico nominal. A Yuhknoʔm Yihch’aak K’ahk’ se le retrata ataviado como el dios patrono de su dinastía, que genera el movimiento permanente del cosmos, y vinculado con el centro de México.

Teachers should pay attention to the deep integration of information technology and mathematics courses, so as to achieve the effect that traditional teaching methods are difficult to achieve. Conic section in high school is an important carrier for cultivating students' mathematical literacy, but it is highly abstract and comprehensive, making it a "difficult point" in high school mathematics teaching. Hawgent dynamic mathematics software has powerful dynamic and visual functions, which can effectively assist the teaching of ellipse in high school. The questions to be studied in this paper are: (1) describe how teachers use Hawgent dynamic mathematics software to design learning media when teaching the content of conic section and stimulate students' for knowledge; (2) describe how Hawgent dynamic math software be used in class to help students understand the definition of conic section effectively. This research was used the research method combining ADDIE model and teaching experiment to analyze the class using Hawgent dynamic mathematics software to design learning materials and the class using traditional teaching method. Research sample was 130 high school students. Mathematical software design learning materials, can give students an intuitive presentation of the formation process of the conic, so as to help students effectively understand mathematical concepts and stimulate students' curiosity for knowledge.

This study discusses the urgency of introducing the concept of numeracy literacy in early childhood. Numerical literacy is one of the most needed skills in facing the 21st century, especially for the young generation. The question still remains, when should these skills be introduced and trained to the young generation candidates. Should it be introduced and taught from an early age? The purpose of this study was to determine the urgency of introducing the concept of numeracy literacy in early childhood. This study uses a literature review method where the authors collect 7 studies related to numeracy literacy in early childhood. From the results of the review that the author conducted on the seven related articles, there are 3 (three) important reasons why numeracy literacy should be introduced to early childhood. Based on these reasons, the authors conclude that the urgency of introducing the concept of literacy to early childhood is quite high, because numeracy literacy is a basic skill that must be possessed in the 21st century and early childhood is a golden age where the level of intellectual maturity of children is formed up to 80%.

Sliced kebab meat is produced by roasting raw kebab meat to make it easier to distribute at cold temperature. However, its quality could be damaged if it is distributed for long period, so preservative is needed. The study consisted of two phases. The first phase determined the type and concentration of preservatives consisting of potassium sorbate at concentrations of 750, 1000, 1250 ppm, and sodium nitrite at concentrations of 30, 50, and 100 ppm used a completely randomized design. The second phase was carried out to study the stability of sliced kebab meat with the addition of selected preservatives during refrigeration storage (5°C). The results showed that the best treatment was the use of potassium sorbate at 1250 ppm which resulted in the lowest mean total plate count (TPC), mold yeast values, and the highest scores of sensory attributes. The stability could be maintained at refrigeration storage for up to 14 days. On the 14th day, the sliced kebab meat had a pH value of 6.59, aw of 0.70, total acidity of 0.55%, TPC of 2.81 logs CFU/g, the color score of 3.8 (slightly brownish red), the aroma of 4 (typical meaty smell), the taste of 3.8 (slightly the savory), the texture of 3.5 (neutral) and overall of 3.5 (rate as liked).

Amaç: Bu çalışma, Giresun’un farklı ilçelerinde (Merkez, Bulancak, Espiye, Eynesil, Güce, Keşap, Tirebolu ve Yağlıdere) yetiştirilen ‘Hayward’ kivi çeşidinin (Actinidia deliciosa) solunum hızı, ağırlık kaybı, meyve eti sertliği, suda çözünür kuru madde miktarı (SÇKM), titre edilebilir asitlik ve C vitamini gibi kalite özelliklerinin soğukta muhafaza süresince değişimini belirlemek amacıyla yürütülmüştür. Materyal ve Yöntem: Meyveler, 0±0.5 °C ve %90±5 oransal nem koşullarında 5 ay boyunca muhafaza edilmiştir. Ölçüm ve analizler aylık olarak yapılmıştır. Araştırma Bulguları: Soğukta muhafaza süresinin tüm ölçüm dönemlerinde, Espiye Merkez, Keşap (150. gün hariç), Tirebolu ve Yağlıdere’de yetişen meyvelerin benzer seviyede, fakat Bulancak, Eynesil ve Güce ilçelerinde yetişen meyvelere kıyasla önemli derecede daha düşük ağırlık kaybına sahip olduğu görülmüştür. Soğukta muhafazanın 120. ve 150. gününde, tüm meyvelerin solunum hızı benzer seviyede bulunmuştur. Soğukta muhafaza süresince, Merkez ilçede yetişen meyvelerin sertliği (dijital ölçüm), diğer yetiştiricilik alanlarına kıyasla önemli derecede daha yüksek olmuştur. Soğukta muhafazanın sonunda Bulancak ilçesinde yetişen meyvelerden, diğer meyvelere kıyasla önemli seviyede daha yüksek SÇKM ölçülmüştür. Halbuki Bulancak, Keşap ve Yağlıdere’de yetişen meyvelerde diğer meyvelere kıyasla önemli seviyede daha yüksek pH belirlenmiştir. En yüksek titre edilebilir asitlik ise Merkez’de yetişen meyvelerden elde edilmiştir. C vitamini içeriği bakımından Bulancak ve Tirebolu ilçelerinde yetişen meyvelerin diğer ilçelere kıyasla önemli derecede daha yüksek seviyede olduğu görülmüştür. Sonuç: Giresun ilinin farklı ilçelerinden hasat edilen ‘Hayward’ kivi çeşidi meyvelerinin muhafaza süresince kalite özelliklerinin değişimi üzerinde ekolojik koşulların farklılığının etkili olduğu saptanmıştır.

Amaç: Bu çalışmada ultraviyole ışık ve sıcak havayla kurutma uygulamalarının üç farklı kayısı çeşidindeki (Prunus armenica L., var. Hacıhaliloğlu, Prunus armenica L., var. Kabaaşı, Prunus armenica L., var. Şekerpare) yüzey mikroorganizma yüküne (psikrofilik ve mezofilik aerobik bakteriler, maya ve küf) etkileri araştırılmıştır. Materyal ve Yöntem: Ultraviyole ışık ortalama doz oranı 6.70 W/m2 ve ışıma maruziyeti (dozaj) 2.01 kJ/m2 olarak uygulanmıştır. Kurutma 70 °C de kayısıların nem içeriği %19’a düşünceye kadar yapılmıştır. Araştırma Bulguları: Çalışma sonucunda Şekerpare çeşidinin diğer iki kayısı çeşidine göre başlangıç mikrobiyal yükünün açıkça daha yüksek olduğu görülmüştür. Ultraviyole ışık ve sıcak hava ile kurutma uygulamaları kayısıların yüzeyinde bulunan doğal mikroflorayı azaltmıştır. Bu azalma, sıcak hava ile kurutma uygulaması için sadece Şekerpare çeşidinde önemli bulunmuştur. Ultraviyole ışık uygulamasının etkisi maya ve küf açısından tüm çeşitlerde önemsizken, mezofilik ve psikrofilik aerobik bakteriler için sadece Şekerpare çeşidinde, toplam mikrobiyal yük için ise Şekerpare ve Hacıhaliloğlu çeşidinde önemli olmuştur. Ultraviyole ışık ve ardından sıcak hava ile kurutma uygulanması durumunda ise meydana gelen azalma mezofilik aerobik bakteriler ile maya ve küf sayıları açısından Şekerpare çeşidinde, psikrofilik aerobik bakteri sayıları ve toplam mikrobiyal yük açısından ise tüm çeşitlerde önemli bulunmuştur. Sonuç: En etkili yöntem UVC ve sıcak hava ile kurutma uygulamasının birlikte uygulanması olduğu sonucuna varılmıştır. Bu yöntemlerin ayrı ayrı kullanılması durumunda etkinlik sırasının değiştiği ve yapılan uygulamaların en fazla psikrofilik aerobik bakteri sayınının azaltılmasında etkili olduğu da tespit edilmiştir.
