DISTANCE LEARNING EXPERIENCES OF JUNIOR HIGH SCHOOL MATHEMATICS STUDENTS

Field: Social Sciences (Social Sciences)

COVID-19 had resulted in significant educational reforms. Face-to-face classrooms were transformed into other learning modalities, including distance learning. Learning was possible but has challenges as well. As a result, the purpose of this study was to determine the experiences of junior high school students in the District 1 Province of Batangas in the pre-implementation of distance learning in the new normal. Specifically, it aimed to achieve the following statements: [1] describe the distance learning experiences of mathematics students in the following as assessed by teachers and students themselves specifically with [1.1] modular distance learning; [1.2] online distance learning; and [1.3] tv/radio-based instruction, [2] find the difference in the assessments made by the teachers and students, and [3] identify the coping mechanism in the difficulties encountered in distance learning. The respondents were selected through a multi-stage sampling and answered the survey questionnaire through a Google form. The documented assessments were recorded and coded. Results identified that the student’s experiences in the new normal can be summarized into three significant themes: having difficulties answering their modules, spending their whole day finishing their assignments, and fearing nothing learned in the modality they chose for their distance learning. However, there was a significant difference in the assessment made by mathematics students and teachers in modular distance learning. On the other hand, there was no significant difference in the assessment made in online distance learning. Additionally, the students' coping mechanisms had three themes; taking a bath, organizing things for a conducive environment, and thinking positively. The following conclusions were drawn based on the findings: In distance learning, the majority of students struggled to study independently; there was a significant difference in teacher and student assessments in modular distance learning; and students in distance learning require support from their parents and teachers.
Chicken Primordial Germ Cell Surface Marker

Field: Agricultural and Biological Sciences (Life Sciences)

The creation of transgenic chickens holds significant promise for the agricultural and biotechnological sectors, offering potential improvements in disease resistance and production efficiency. The preferred method for generating gene-edited chickens involves the genetic manipulation of primordial germ cells (PGCs), making the identification and isolation of these cells a growing focus of research. PGCs are the precursors to sperm and oocytes, responsible for transmitting genetic material to the next generation. In humans, PGCs are characterized by their large size, round nuclei, and refractive lipids in the cytoplasm, and can be identified using periodic acid–Schiff (PAS) staining and the surface marker stage-specific embryonic antigen 1 (SSEA1). Similarly, chicken PGCs express SSEA1, but their most specific marker is the chicken vasa homologue (CVH), the avian equivalent of the RNA-binding factor gene vasa. However, SSEA1, along with other known surface markers, does not bind to all PGCs or lacks specificity, while CVH, although highly specific to PGCs, is intracellular and unsuitable for isolating viable cells. This study aims to develop an antibody targeting a PGC surface marker with the same specificity as CVH. Despite the importance of identifying surface markers for PGC characterization, to date, such reagents are limited. To address this, whole chicken PGCs were injected into mice, leading to the generation of a panel of monoclonal antibodies. One antibody was found to bind cultured chicken PGCs and showed reduced expression upon differentiation with retinoic acid, indicating its specificity to PGCs. Immunoprecipitation followed by mass spectrometry identified the antigen as myosin heavy chain-like (MYH9) protein. The antibody, αMYH9, was further characterized and shown to bind circulating PGCs and embryonic gonadal PGCs (Hamburger Hamilton (H-H) stage 30, embryonic day 6.5–7). Whilst our primary aim was to determine the binding to PGCs, further investigation is required to determine potential binding to somatic cells. In conclusion, this study provides the characterization of a surface marker for chicken PGCs, with significant implications for advancements in avian genetic preservation, agriculture, and biotechnology.
A Compact and Scalable Hardware/Software Co-design of SIKE

Field: Computer Science (Physical Sciences)

We present efficient and compact hardware/software co-design implementations of the Supersingular Isogeny Key Encapsulation (SIKE) protocol on field-programmable gate arrays (FPGAs). In order to be better equipped for different post-quantum scenarios, our architectures were designed to feature high-flexibility by covering all the currently available parameter sets and with support for primes up to 1016 bits. In particular, any of the current SIKE parameters equivalent to the post-quantum security of AES-128/192/256 and SHA3-256 can be selected and run on-the-fly. This security scalability property, together with the small footprint and efficiency of our architectures, makes them ideal for embedded applications in a post-quantum world. In addition, the proposed implementations exhibit regular, constant-time execution, which provides protection against timing and simple sidechannel attacks. Our results demonstrate that supersingular isogeny-based primitives such as SIDH and SIKE can indeed be deployed for embedded applications featuring competitive performance. For example, our smallest architecture based on a 128-bit MAC unit takes only 3415 slices, 21 BRAMs and 57 DSPs on a Virtex 7 690T and can perform key generation, encapsulation and decapsulation in 14.4, 24.4 and 26.0 milliseconds for SIKEp434 and in 52.3, 86.4 and 93.2 milliseconds for SIKEp751, respectively.
“The Faggot God is Here!”

Field: Arts and Humanities (Social Sciences)

This chapter analyzes the language of religious music among radical faeries, a gay subculture founded in Neopagan religion. The analysis focuses on Ye Faerie Hymnal, a collection of songs used during faerie gatherings (in which faeries meet together in a rural or outdoor setting, usually for several days). Particular attention is given to Bakhtin’s concept of chronotopes, or the spatial and temporal associations indexed by a particular use of language. The songs in the hymnal index chronotopes associated with anti-Christian stances. The songs include multiple appropriations from religious traditions that have historically been oppressed by Christian groups. The songs also index chronotopes specific to radical faerie history, including prior faerie gatherings. Particular attention is given to the ways in which the songs reproduce radical faerie ideologies of gay male androgyny.
Financial systems, investment in innovation, and venture capital: the case of China

Field: Economics, Econometrics and Finance (Social Sciences)

This book examines the role of venture capital institutions in financing technology-based ventures both in developed and developing countries. It also explores that part of venture capital activity which is hitherto vastly under-researched; namely the ability of venture capital institutions to render a whole host of value-added support functions. These include setting up management teams and designing strategic plans for fledgling enterprises. The latter issue is operationalized through a series of carefully chosen case studies.
Unusual complications of ventriculo peritoneal shunt surgery

Field: Medicine (Health Sciences)

ABSTRACT Ventriculo peritoneal (VP) shunt surgery is one of the common neurosurgical procedures employed in the management of hydrocephalus. Numerous complications related to this procedure are reported in the literature. Peritoneal catheterrelated complications are the usual causes of the shunt malfunction. We report three unusual cases of peritoneal shunt catheter migration in children. Two cases are of anal and one vaginal extrusion. Possible mechanisms of migration and management strategies were discussed.
Ratoon rice allows millions of smallholders to meet production and environmental goals

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract

China aims to increase rice production and reduce associated negative environmental impact. However, increasingly limiting and expensive rural labor has driven a shift from double- to single-season rice, posing a threat to national food security. Here, we evaluated the impact of an alternative ratoon rice system on production and environmental outcomes using smallholders’ survey data together with spatial crop modeling. We showed that ratoon rice adoption would ensure rice self-sufficiency and drastically reduce nutrient losses, pesticide use, greenhouse gas emissions, and labor requirements. We conclude that ratoon rice is a viable option to meet the dual goal of increasing production and reducing negative environmental impacts.
Nursing Students’ Perceptions and Acceptance of Online Learning during the COVID-19 Pandemic in Indonesia

Field: Nursing (Health Sciences)

BACKGROUND: The COVID-19 pandemic has changed the order of life in various aspects of life, including the field of education in Indonesia. AIM: The purpose of the study was to determine student perceptions and acceptance of the online learning process during the COVID-19 pandemic. METHODS: The research is in the form of a survey using Google Forms about the perception and acceptance of online lectures during the COVID-19 pandemic for nursing students at universities in Indonesia, a questionnaire sent via Whatsapp. Held from July 1, 2021, to July 30, 2021. RESULTS: The many of respondents aged 17-19 years (50%) with a Diploma-students (62.9%). Most of them have intermediate-level skills in using information technology (82.2%). The platform that is often used is Zoom meeting. While other platforms are Whatsapp and Edmodo. The advantages of online learning are that students state that they can study from home (22.2%) and easily access online sources of material (19.9%) and can obtain recordings of each lesson (18.6%). Constraints that are often faced are technical problems (24.6%), very minimal interaction with lecturers (18.4%) and very minimal interaction between students (17.5%). Age and skills in using technology, information, and communication have a significant effect on students' perceptions of online learning (p<0.05). Most respondents have a negative perception (52.2%) about online learning. CONCLUSION: Although there are several advantages to online learning, students' perceptions of the learning process are negative, meaning that they are happier and still want face-to-face learning.
Creating Stronger Design Systems for Collaboration: Skills, Resources, and Practices Needed to Support an Effective Co-Design Experience

Field: Health Professions (Health Sciences)

This paper describes a design case that addressed a healthcare training need for clinicians and administrators about Value-Based Care (VBC) through the design, development, implementation, and evaluation of seven massive open online courses (MOOCs). The context was an industry-academic partnership that linked subject matter experts in VBC with university faculty and designers. Courses were developed using a co-design approach to provide multiple perspectives on the issues involved, ensure the accuracy of the content, and enhance the alignment between the design and stakeholders’ needs. The team worked collaboratively to define the opportunity, brainstorm ideas, prototype solutions, evaluate prototypes based on identified needs, and ultimately design online educational experiences for a wide variety of learners in different healthcare contexts. This paper shares lessons learned about creating stronger design systems for collaboration in the areas of selecting and supporting co-design teams, fostering collaborative learning environments, and modeling collaboration in the instructional design process. Reflections about this design case underscored the importance of forming relationships among team members, which was a key outcome of the co-design structure and, facilitated the communication and psychological safety needed to support the iterative cycles of feedback during course development.
FORMATION OF INFORMATION AND DIGITAL COMPETENCE OF EDUCATION SEEKERS WHEN TEACHING MATHEMATICS

Field: Social Sciences (Social Sciences)

The transformation of education is associated with the penetration of digital technologies into everyday life. There is an information overload, which requires the ability to work with information, evaluate, consider different aspects of problem solving, and draw the right conclusions. There is a need to form one of the key competencies in schoolchildren – information and digital when teaching subjects, in particular, mathematics. The purpose of the article is to study the features of the formation of information and digital competence of education seekers and to describe mathematics tasks that, using digital technologies and modern teaching methods, contribute to the formation of 21st-century skills in schoolchildren. For this purpose, the following research methods were used: analysis of literature, regulatory documents, description, and generalization. An analysis of literature, regulatory documents showed that international educational policy, including in Ukraine, is focused on personal and competency-based learning, which involves the formation of information and digital competence in education seekers. The authorʼs vision of the formation of information and digital competence of education seekers in mathematics lessons is highlighted, and a description of its implementation is made through the task of finding the smallest values of quantity. The influence of the selection of developmental mathematics tasks using activity and search and research approaches on the formation of schoolchildren's information and digital competence was revealed, which contributes to the development of flexibility, creative thinking, and the ability to produce new things. As a result of the study, the conclusion was made that the formation of schoolchildren's information and digital competence in mathematics lessons in modern realities is a necessary condition for high-quality education today.
The clinical presentation of Von Meyenburg complexes.

Field: Medicine (Health Sciences)

Von Meyenburg Complexes (VMCs) is a rare clinicopathologic entity, consisting of small (<1.5cm), usually multiple and nodular cystic lesions. VMCs typically cause no symptoms or disturbances in liver function and thus in most instances they are diagnosed incidentally. We present four VMCs cases, each with a distinct clinical presentation. In two of our cases, VMCs caused mild, non-specific abdominal symptoms, including diffuse abdominal pain and discomfort. In the other two cases, in a 60-year-old woman and a 25-year-old man, the clinical presentation was implicative of an infectious hepatic process reminiscent of cholangitis and liver abscesses respectively. In each case the diagnosis was based on magnetic resonance imaging and magnetic resonance cholangiopancreatography findings showing multiple hyper-intense cystic nodules not communicating with the biliary tree. Physicians should be aware of the entire clinical spectrum of VMCs and its unique radiologic features in order to differentiate VMCs from other cystic liver lesions.
Human Hair Growth Deficiency Is Linked to a Genetic Defect in the Phospholipase Gene LIPH

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The molecular mechanisms controlling human hair growth and scalp hair loss are poorly understood. By screening about 350,000 individuals in two populations from the Volga-Ural region of Russia, we identified a gene mutation in families who show an inherited form of hair loss and a hair growth defect. Affected individuals were homozygous for a deletion in the LIPH gene on chromosome 3q27, caused by short interspersed nuclear element–retrotransposon–mediated recombination. The LIPH gene is expressed in hair follicles and encodes a phospholipase called lipase H (alternatively known as membrane-associated phosphatidic acid–selective phospholipase A1α), an enzyme that regulates the production of bioactive lipids. These results suggest that lipase H participates in hair growth and development.
A model for Jupiter's proton radiation belt

Field: Physics and Astronomy (Physical Sciences)

A model for electron and proton energy and density in Jupiter's radiation belt is proposed. It is assumed that electrons diffuse inward from the solar wind. The Davis and Chang diffusion model, in which there is a very steep L-shell dependence in density and energy, is scaled outwards from the peak of the belts at about 1.5 to 2 Jupiter radii to the magnetopause as defined by the magnetic moment. The energetic electron density is calculated to be one billionth of the density in the solar wind, and that is assumed to be the trapping ratio of Jupiter's synchrotron belts. It is further assumed that the same figures apply to protons. The flux density at 80 MHz was measured by the Culgoora ring to be identical to that at 3000 MHz, implying a constant flux density of the synchrotron source of over 20 or 30 to 1 in frequency. It is suggested that the synchrotron spectrum is flat over more than an order of magnitude of frequency. Jupiter is an enormous synchrotron source and has a strong magnetic field, causing long diffusion times for electrons in the magnetosphere.
Induction of Integral Membrane PAM Expression in AtT-20 Cells Alters the Storage and Trafficking of POMC and PC1

Field: Neuroscience (Life Sciences)

Peptidylglycine α-amidating monooxygenase (PAM) is an essential enzyme that catalyzes the COOH-terminal amidation of many neuroendocrine peptides. The bifunctional PAM protein contains an NH2-terminal monooxygenase (PHM) domain followed by a lyase (PAL) domain and a transmembrane domain. The cytosolic tail of PAM interacts with proteins that can affect cytoskeletal organization. A reverse tetracycline-regulated inducible expression system was used to construct an AtT-20 corticotrope cell line capable of inducible PAM-1 expression. Upon induction, cells displayed a time- and dose-dependent increase in enzyme activity, PAM mRNA, and protein. Induction of increased PAM-1 expression produced graded changes in PAM-1 metabolism. Increased expression of PAM-1 also caused decreased immunofluorescent staining for ACTH, a product of proopiomelanocortin (POMC), and prohormone convertase 1 (PC1) in granules at the tips of processes. Expression of PAM-1 resulted in decreased ACTH and PHM secretion in response to secretagogue stimulation, and decreased cleavage of PC1, POMC, and PAM. Increased expression of a soluble form of PAM did not alter POMC and PC1 localization and metabolism. Using the inducible cell line model, we show that expression of integral membrane PAM alters the organization of the actin cytoskeleton. Altered cytoskeletal organization may then influence the trafficking and cleavage of lumenal proteins and eliminate the ability of AtT-20 cells to secrete ACTH in response to a secretagogue.
Dysregulation of cyclin D1 by translocation into an IgH gamma switch region in two multiple myeloma cell lines [see comments]

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Translocations involving the IgH locus at chromosomal locus 14q32.3 are a common event in many B-cell malignancies. The translocations, which generally occur into JH and switch regions, are mediated by errors in the two developmentally regulated, lymphocyte-specific pathways: VDJ- and switch-mediated recombination. Dysregulation of cyclin D1 by a t(11;14)(q13;q32) translocation occurs in most cases of mantle-cell lymphoma and in approximately 30% of multiple myeloma (MM) tumors in which a 14q32 translocation can be detected. We show here that in two of three myeloma lines that overexpress cyclin D1, there is an 11;14 translocation into a gamma switch region, suggesting an error in switch recombination. By contrast, 11;14 translocations in mantlecell lymphoma are invariably into or near a JH segment, suggesting an error in VDJ recombination. This is consistent with the fact that myeloma cells have undergone lgH switch recombination, whereas mantle-cell lymphoma cells generally have not.
Accelerated aging of Quercusnigra seed: biochemical changes and applicability as a vigor test

Field: Agricultural and Biological Sciences (Life Sciences)

A decline in germination capacity (vigor) of Quercusnigra L. (water oak) seed lots within 108 h was observed when seeds were aged at 41 °C and 100% relative humidity. Aging for less than 108 h increased germination rate. Seed moisture and amino nitrogen contents increased with period of aging, whereas starch content gradually declined. There was no definitive pattern of change in the contents of reducing and nonreducing sugars. These changes reflected an overall elevated metabolism that resulted in an increased rate of utilization of seed energy reserve and a consequent decline in seed vigor.
ETIOLOGIC STRAINS OF TRICHOPHYTIA IN OUR CLINIC DURING THE PAST 6 YEARS.

Field: Medicine (Health Sciences)

For the past 6 years we have cultivated 322 strains isolated from cases of trichophytia in our clinic. Microsporon japonicum was isolated from all of 35 cases with trichophytia superficialis capillitii, Trichophyton asteroides from 4 with kezion celsi, and 236 strains of Tr. purpureum, 22 strains of Tr. asteroides, 3 strains of Mic. japonicum and each 11 strains of Tr. interdigitale and Epidermophyton inguinale from several other clinical types of trichophytia superficialis.The comparison of these with the results obtained during the preceding 9 years revealed a noteworthy fact that the number of cases of Tr. purpureum and Ep. inguinale increased.

Mobility management of interconnected virtual LANs over ATM networks

Field: Computer Science (Physical Sciences)

One of the most powerful virtual LAN (VLAN) features is the capability to group users into broadcast domains, which are independent of their locations on the physical network. This paper deals with VLAN services using ATM LAN emulation technology which operates on a client/server model, and focuses on the issues of supporting transparent VLAN services for mobile terminals. A mobile VLAN architecture is proposed to efficiently maintain multiple VLAN broadcast domains over ATM networks even if the topology is changed dynamically due to mobility. This architecture exploits a hypercube over tree (HOT) hierarchical structure, i.e., trees are connected in a hypercube manner, to interconnect different VLANs servers. To filter excessive server-to-server traffic, an intelligent frame forwarding algorithm is proposed for the servers. The proposed mobile VLAN system brings us a step closer towards facilitating mobility and conforms to existing LAN emulation environment.
