Authors: Isnaningsih Tantiana , Setyaningsih Nisa Angraeni
Published: February 2022

Pendahuluan: Indonesia merupakan salah satu negara yang menghadapi beban ganda atau double burdenof Malnutrition (DBM) terhadap permasalahan gizi yang berimpas pada kualitas sumber daya manusia. Saat ini Pemerintah terus berupaya untuk melakukan perbaikan gizi dengan cara meningkatan mutu gizi pada individu dan komunitas. Stunting merupakan masalah kesehatan masyarakat yang sangat penting karena memiliki dampak yang besar terhadap kualitas SDM pada satu generasi. Menurut UNICEF tahun 2018 bahwa hampir 3 dari 10 balita Indonesia menderita stunting atau terlalu pendek untuk usia mereka. Dampak yang ditimbulkan dari adanya stunting bukan hanya dirasakan oleh setiap individu saja, melainkan berdampak pada keluarga, masyarakat, komunitas, bahkan sampai negara. Hal ini disebabkan karena menurunnya tingkat produktivitas, tidak mampu bersaing produktif sesuai dengan usianya, pendapatan yang rendah ketika bekerja, sehingga secara otomatis terjadi penurunan kualitas sumber daya manusia yang secara nasional akan menghambat pertumbuhan dan perkembangan negara dalam berbagai bidang. Metode: Desain penelitian ini adalah penelitian deskriptif dengan rancangan cross sectional. Sampel sebanyak 30 ibu dari bayi usia 6-24 bulan yang masuk kategori stunting di Desa Pakunden, Desa Bligo dan Desa Blongkeng dipilih menggunakan proporsionate stratified random sampling. Data dianalisis dengan menggunakan uji chi square. Hasil: Terdapat korelasi antara pengetahuan ibu dalam pemberian MP-ASI dengan kejadian stunting pada bayi usia 6-24 bulan yaitu nilai p = 0,029 < a = 0,05 dan terdapat korelasi antara sikap ibu dalam pemberian MP-ASI dengan kejadian stunting pada bayi usia 6-24 bulan yaitu nilai p = 0,013 < a = 0,05. Kesimpulan: Ada hubungan antara pengetahuan ibu dalam pemberian MP-ASI dengan kejadian stunting pada bayi usia 6-24 bulan dan ada hubungan antara sikap ibu dalam pemberian MP-ASI dengan kejadian stunting pada bayi usia 6-24 bulan

The intricate Pinguicula crystallina/hirtiflora-complex
Authors: Fleischmann Andreas
Published: February 2022

The Pinguicula crystallina/hirtiflora-species-aggregate (Pinguicula section Cardiophyllum, which will be further simply called the “P. crystallina-complex” here) comprises rosetted perennial temperate butterworts of homophyllous growth type (the latter means that carnivorous leaves are produced throughout the year, no hibernacula or non-carnivorous winter leaves are present, and the plants hibernate with open leaf rosettes) that are distributed in the Mediterranean (southern Italy, the Balkans, and Greece) and Asia Minor (Cyprus and Turkey).
Germinating Nepenthes seed: Putting myths to rest
Authors: McNair Mason , Harris Jeremiah
Published: February 2022

The Internet is full of personal accounts and guides on how to grow Nepenthes from seed. However, there is a plethora of misinformation available. Many of these myths involve the treatment of Nepenthes seeds before they are sown. In particular, whether they require a dark period in order to induce germination. A period of darkness after being sown has been shown to increase germination in other genera of plants such as Cyclamen, but there has been no conclusive study whether Nepenthes require a dark period to germinate. Others swear that treating seeds with gibberellic acid (GA3) can aid in the germination of Nepenthes seed. Again, no conclusive study has been published on this claim. The final claim is that sowing seeds and putting the pot on top of a heat mat will increase germination. Again, no study has been published legitimizing this claim. This study is an attempt to put many of these myths to rest. We hypothesize that none of the treatments will yield better results than the control treatment.

Is long-term survival of dried turions of aquatic carnivorous plants possible?
Authors: Adamec Lubomír
Published: February 2022

Turions of perennial aquatic carnivorous plants of the genera Aldrovanda and Utricularia are dormant, overwintering buds and are formed by extreme condensation of short, modified leaves in the shoot apex at the end of the growing season. These tough organs represent also storage organs both for carbohydrates and some mineral nutrients (N, P) and their respiration rate is greatly reduced as compared to that of summer shoots.
Hypothesis of mucilage-assisted dispersal of Drosera seeds
Authors: Gibson Robert
Published: February 2022

Several Drosera taxa occur in seasonally wet herbfields on the upper slopes of isolated granite outcrops in inland South Western Australia. These habitats are naturally irrigated by runoff from adjacent rock surfaces. Many of these sundews that grow here, particularly rosetted tuberous sundews (Drosera subgenus Ergaleium section Erythrorhiza) and fan-leaved sundews (D. subgenus Ergaleium sect. Stolonifera) produce spherical seeds around 1 mm diameter that lack obvious surface characters to readily facilitate dispersal to other granite outcrops. Yet these sundews are common components of these habitats in the region. How then did these sundews spread across the landscape when their seed appear to be poor candidates for long-distance dispersal?
An equation for determining percentage of herbivory on Pinguicula moranensis ' A correction
Authors: Baldwin Michael , Baldwin Robert
Published: February 2022

Recently Alcalá et al. (2010) explored the potentially defensive function of sticky traps in Pin- guicula moranensis. Specifically, the authors assessed the defensive role of glandular trichomes in the interaction between P. moranensis and its insect herbivores. Alcalá et al. (2010) offered a unique digital photography tool and a method for determining the amount of herbivory. To create a baseline level of insect herbivory the authors developed an equation to determine the percentage of leaf herbivory. Unfortunately, the equation published in the article contained an error. The goal of this article is to offer a correction to the error.

Published: February 2022

We present a taxonomic analysis of contents of Nepenthes smilesii Hemsley, 1895 (Nepenthaceae) pitchers collected in Bi Doup – Nui Ba National Park (South Vietnam). 230 specimens of insects, belonging to 7 orders and 17 families, as well as 7 specimens of arachnids (2 orders), 2 specimens of chilopods, 2 specimens of isopods and 1 specimen of oligochaetes were identified. Animal composition from N. smilesii pitchers is dominated by flightless and poorly flying invertebrate forms. Small ant species Technomyrmex yamanei Bolton, 2007 is a predominant prey. Besides ants, Heteroptera and Blattodea are groups dominating in ration, that distinguishes N. smilesii from other Nepenthes species, studied before in this context.

Drosera pauciflora Banks ex DC is a flat-rosetted sundew endemic to the Western Cape of South Africa which produces flowers up to 6 cm diameter that are the largest in the genus. These magnificent flowers make Drosera pauciflora an apt queenly partner to the king sundew, Drosera regia. Drosera pauciflora is perhaps better known from plants in cultivation than in the wild, to help rectify this I present information from field and herbarium studies to give this species more context.
The search for all of the victims and all of the killers
Authors: Darnowski Douglas W.
Published: February 2022

Carnivorous plants often claim the name “insectivorous” for the simple reason that most carnivorous traps usually contain insects, and, even when not insects, trapped prey are usually close cousins of the insects from within the Phylum Arthropoda. An example of this is when bladderworts (Utricularia spp.; Lentibulariaceae) trap crustaceans such as amphipods and copepods, which are arthropods, like insects. Indeed, Darwin’s book on the carnivorous plants recognizes this fact with its title Insectivorous Plants. Splitting open a pitcher from Sarracenia leucophylla, as an example, usually reveals one chitinous arthropod exoskeleton after another.

Literature Review on the Effect of Balanced Scorecard on Employee Wellbeing
Authors: Peri Cignitas Ceren , Antonio Torrents Arevalo Juan , Vilajosana Crusells Jordi
Published: February 2022

Employee well-being is an important key area of human resource development (HRD), such as performance measurement, employee productivity, employee development, and motivation. Employees are a key element in realizing the organization's strategies. For this reason, measuring employee performance is important in terms of ensuring the efficiency and sustainability of the system and is an HR Strategy. The aim is to determine whether there is a quasi-experimentally demonstrable relationship between. Balanced Scorecard (BSC), and employee well-being. The study conducted qualitative and quantitative research based solely on the bibliographical review of previous theoretical/conceptual and empirical articles on the subject. Quantitative measurement data were collected from 9 empirical studies, and a total of 121 qualitative studies were reviewed. The findings of the study proved that there is a strong relationship between employee happiness and the increase in performance of organizations, while the BSC application increases employee happiness and indirectly the happiness of the organization. This article is an important reference work for HR development with Balanced Scorecard strategies.
The Marginal Propensity to Consume of 2020 COVID-19 Stimulus Payments in Peru
Authors: Crozier Stephen L. , Zavaleta Fernando Burgos
Published: February 2022

The COVID-19 pandemic has led to unprecedented economic challenges across the world. To combat these challenges, the government of Peru used fiscal stimulus in the form of direct subsidies paid to vulnerable populations for social protection and to stimulate the economy. Using 514 survey responses collected both in-person and online, the objectives of this study were to calculate the marginal propensity to consume (MPC) for Peruvian subsidy recipients and to evaluate the heterogeneity amongst beneficiaries based on four individual factors: pre-pandemic savings, financial inclusion (bank account ownership), survey response type (online vs in-person), and domicile location (residing in Lima Metro or not). Overall, survey responses showed an average MPC of 0.89, which was greater than subsidy-inspired MPC studies from high-income countries like the United States, United Kingdom, and Japan. There was a statistically significant relationship between MPC and liquidity, which corroborated previous studies on MPC from other countries. Relationships between similar programs in Peru and high-income countries for the impact, effectiveness, and purpose of direct stimulus payments are discussed.

Published: February 2022

Education plays an important role in human development. Through learning, humans are enabled to write, speak, and create. The Covid-19 pandemic has disrupted education, especially for those who depend on free educational programs that rely on volunteers for day-to-day operation. Children in the golden age are the most affected. Online learning can never cover the social interaction provided by offline learning. This research was done in Rumah Langit, which is a free community learning center for children, located in Rusunawa Urip Sumoharjo, Surabaya. After several months of getting to know the people involved, their surrounding environment, and participating in their daily activities, it could be clearly seen that Rumah Langit was lacking learning media. Especially learning media for children in the golden age who are often very curious and are in the stage of developing their five senses. OTTM (One, Two, Three, More?) is a modular furniture unit specifically developed for learning media at home for preschoolers, designed using the six steps of the design thinking method (Understand, Observe, Define Point of View, Ideate, Prototype, and Test). With its endless configurations, OTTM can be used as an open storage, a table and chair set for preschoolers, a seating chair for adults, and learning media for kids. It was inspired by the Montessori method of learning, which allows children to be creative and learn at their own pace. OTTM offers an easy and fun way of learning at home for children, especially for children in the golden age. By using OTTM, children can learn about basic counting, colors and how primary colors create secondary colors, and about shapes, from geometric to organic shapes.

Liver Histology in Septic Patients: Is It All About Ductular Cholestasis?
Authors: Bsirini Caroline , Katerji Roula , Lee Edwin J. , Gonzalez Raul S.
Published: February 2022

Context.—

Cholestasis within bile ductules is touted as a key histologic finding in septic patients but is not entirely sensitive or specific. The spectrum of other histopathologic findings in septic patients has not been thoroughly studied.

Objective.—

To evaluate histologic features in liver biopsies from septic patients, as well as mimics.

Design.—

For 121 liver samples where sepsis was mentioned in provided clinical information or in the pathologic differential diagnosis, we compiled patient outcome, clinical impression (sepsis or not), and blood culture results. We evaluated each case for inflammatory and cholestatic histologic findings, comparing them between patients with and without clinical sepsis, and between patients with gram-positive versus gram-negative results on blood culture.

Results.—

Cases from clinically septic patients (n = 77) showed portal mononuclear inflammation (52 cases, 68%), lobular neutrophilic inflammation (45, 58%), ductular reaction (58, 75%), lobular cholestasis (68, 88%), ductular cholestasis (52, 68%), and acidophil bodies (36, 47%). Findings between clinically septic and nonseptic patients were similar, though the latter more often had lobular mononuclear inflammation (19% versus 45%, P = .004). Ductular cholestasis rates were similar in both groups (68% versus 55%, P = .17). Ductular cholestasis had a sensitivity of 68%, a specificity of 45%, a positive predictive value of 68%, and an accuracy of 60% for the diagnosis of sepsis. Gram-positive and gram-negative sepsis caused comparable findings.

Conclusions.—

Ductular cholestasis can be present in septic and nonseptic liver samples, though its presence does suggest the possibility of sepsis. Other common findings in sepsis include lobular cholestasis, ductular reaction, portal mononuclear inflammation, and lobular neutrophilic inflammation.

Published: February 2022

Background/Aim: This investigation aimed to evaluate the intensity of self-reported pain and frequency of self-medication with analgesics during the initial phase of orthodontic treatment with fixed appliances and to compare possible differences between the maxillary and mandibular teeth. Material and Methods: In this observational clinical trial 68 patients had similar orthodontic forces (the same bracket-slot and prescription, archwire size and material, and treatment plan) applied on maxillary and mandibular teeth. The patients recorded pain intensity and use of analgesics for the first seven days of treatment. Comparisons between maxillary and mandibular teeth regarding the pain intensity and self-medication frequency were performed by Wilcoxson Signed Ranks Test and McNamara Test for Matched Pairs, respectively. Results: The patients reported moderate pain in both jaws which decreased significantly with each day of treatment. Still, during the initial three days of treatment intensity of pain for maxillary teeth was significantly lower compared to the mandibular teeth. Patients reported analgesics consumption for both jaws, without a statistically significant difference between them. Conclusions: The patients have reported orthodontic pain of higher intensity in the mandibular arch compared to the maxillary arch during the initial phase of orthodontic treatment with fixed appliances.

Inspite the constantly growing body of biomedical knowledge and techniques, scientists are still far from a complete understanding of molecular system dysfunctions and their relevance in atherogenesis. Accordingly, cellular non specific esterases represent a special field of research, due to their role in a wide range of diseases, including atherosclerosis. This paper deals with linear correlation between relative a-naphthyl acetate esterase (ANAE) score values and different degrees of carotid stenosis in patients with various morphological atherosclerotic lesions of this blood vessel. In our study analysis of ANAE cytochemical activity was performed in imprints of carotid plaques obtained from patients with different morphological groups of atherosclerotic lesions (n=100), as well as in control group of patients with kinking and/or coiling of carotid arteries (n=25). ANAE status was determined by cytochemical scoring system (Hayhoe and Quaglino's method modified by Cvetković, Radak and Đorđević Denić). Our results show that there is difference in relative score value of ANAE activity in carotid artery/plaque tissue between investigated groups of patients. One can, also, observed linear correlation between relative ANAE score values and different degrees of carotid stenosis in patients with various morphological atherosclerotic lesions of this blood vessel. This findings may indicate importance of ANAE in atherogenesis.

Published: February 2022

Purpose: This study was performed to explore and describe the overall clinical practice adaptation experiences among nursing students during the COVID-19 pandemic.Methods: This qualitative study applied the grounded theory method by Corbin and Strauss. Data were collected from May to August 2021 through individual in-depth interviews with 14 nursing students from three universities in B metropolitan city.Results: From open coding, 20 sub-categories and 10 categories were identified. Analysis revealed that the core category was the process of “keeping the place of learning while adhering to the restrictions of the era of pandemic” and that it consisted of four phases: confusion, withdrawal, adjustment, and growth. Through this process, participants utilized various action/interactional strategies such as “shifting to positive thinking,” “building a shield to protect oneself,” and “focusing on learning.” The consequences of these strategies were “adapting to the reality of the infectious disease situation” and “strengthening a foothold to grow as a future nurse.”Conclusion: An in-depth understanding of nursing students’ experiences of adapting to clinical practice during the COVID-19 pandemic will guide nursing educators to promote effective teaching strategies to better support nursing students in a time of infectious disease crisis.

Published: February 2022

Purpose: This study was conducted to investigate the effect of tuberculosis-related knowledge and family support on medication adherence in tuberculosis patients.Methods: The data were collected from 175 patients diagnosed with tuberculosis at three general hospitals located in two provincial cities in South Korea from September 1 to November 31, 2020. The 160 questionnaires were analyzed using IBM SPSS WIN 25.0.Results: The patients’ average score for tuberculosis-related knowledge was 15.85±5.87 (out of 25), for family support it was 22.03±9.20 (out of 35), and for medication adherence it was 5.11±2.68 (out of 8). There were significant differences in tuberculosis-related knowledge, family support, and medication adherence according to patients’ general characteristics and significant positive relationships among tuberculosis-related knowledge, family support, and medication adherence. Factors affecting patients’ tuberculosis medication adherence were history of stopping the medication, the importance of treatment among tuberculosis-related knowledge and family support, and these factors could explain 78% of patients’ taking tuberculosis drugs.Conclusion: It could be concluded that the importance of tuberculosis treatment and family support are very important for improving patients’ rates of medication adherence. Therefore, medical staffs caring for tuberculosis patients need to manage patients’ medication of tuberculosis drugs with continuous consultation.

Published: February 2022

Artykuł ma charakter teoretyczno-koncepcyjny. Jego celem jest wskazanie możliwości wykorzystania dualizmów stosowanych w socjologii w konceptualizacji i operacjonalizacji badań nad rozwojem społeczno-gospodarczym oraz w wyjaśnianiu mechanizmów zmiany społecznej – siły napędowej rozwoju. Artykuł podkreśla rolę struktury oraz podmiotowego sprawstwa w wyjaśnianiu mechanizmów rozwoju, proponuje prowadzenie badań na kilku poziomach jednocześnie w nawiązaniu do dualizmów metodologicznych w socjologii, a także podaje przykłady dychotomicznych kategoryzacji oraz struktur społecznych, pomocnych w zrozumieniu mechanizmów rozwoju. Włączenie dualizmów socjologicznych w rozważania geograficzne nad rozwojem może wnieść nowe spojrzenie na proces projektowania samych badań, triangulację (łączenie różnych metod analizy), a także wnioskowanie. Dzięki ich wykorzystaniu łatwiej będzie podważyć skłonność geografów do formułowania deterministycznych zależności i postrzegania czynników rozwoju jako sterowalnych i kontrolowanych.
Construcción de masculinidades en los discursos de estudiantes migrantes en Chile
Authors: Contreras-Salinas Sylvia , Ramírez Pavelic Mónica , González-Martínez Carolina , Silva Mendez Matías
Published: February 2022

El objetivo principal del presente artículo fue identificar, en los discursos y contradiscursos de estudiantes varones migrantes con edades entre 12 y 14 años, las concepciones y representaciones asociadas a la construcción de sus masculinidades desde una perspectiva de género. Para ello se utilizó la metodología cualitativa, con la técnica de entrevista grupal y notas de campo. La información recogida fue analizada desde el enfoque psicológico discursivo de Korobov y Bamberg (2004) y desde el análisis de discurso. En el desarrollo de la investigación fue posible visualizar hallazgos relacionados con la percepción de los niños de ser hombres en construcción y de la inexistencia de aportes de la escuela a los procesos de construcción de sus masculinidades. Otro elemento a considerar es la relevancia que los estudiantes migrantes otorgan a su familia y particularmente a la madre, principalmente en aspectos como el cuidado y la afectividad. Asimismo, una de las principales conclusiones, que coincide además con otras investigaciones, revela que, a pesar de algunas excepciones, los estudiantes mantienen una idea patriarcal de lo que significa ser hombre y del rol de este en el orden social, plasmado en la premisa de ser el principal responsable de procrear y proveer.
Holothuriophilus trapeziformisNauck, 1880 (Decapoda: Pinnotheridae) from the Pacific coast of Mexico: taxonomic revision based on integrative taxonomy
Authors: Cortés-Carrasco Fernando , Elías-Gutiérrez Manuel , García-Madrigal María del Socorro
Published: February 2022

Background

Holothuriophilus trapeziformisNauck, 1880 is a holothurian-dweller pinnotherid crab representing one of the two species of the genus distributed along the Pacific coast of Mexico and Chile, respectively. While the parasitic ecological interaction with its host is well established, the morphology of the male remains unknown, and DNA information for the species is not available. Furthermore, the only morphological trait separating both species of the genus is subjective and corresponds to the presence or absence of a gap between the fingers of the chelae. Our goal is to complete and clarify the taxonomic status ofH. trapeziformisand describe the male morphology with the use of the integrative taxonomy, providing additional characters to differentiate this species.

Methods

We collected new biological material in the Pacific coast of Mexico including the topotypes. We also reviewed material from national collections to integrate morphology (based on a complete and detailed description and illustration of the species using light microscopy), ecological data (based on the identification of the host and the place where it was located within the host), and the mtCOI gene information (commonly known as DNA barcode) to differentiateHolothuriophilus trapeziformisfrom other related crabs.

Results

This species presents marked sexual dimorphism only in the primary sexual characters. For the first time we describe morphological variability of traditionally stable characters. In addition to the gap between the fingers of the chelae,Holothuriophilus trapeziformisdiffers fromH. pacificus(Poeppig, 1836) by their ornamentation, the shape of the male abdomen, and the gonopod. Cytocrome Oxidase 1 gene (COI) distance divergence was >3% between bothHolothuriophilusspecies forming a clear clade. DNA barcoding indicates only one taxon, with a maximum divergence of 2.2%. All the specimens have the same Barcode Index Number (BIN; BOLD: ADE9974). All the hosts forH. trapeziformiswere identified asHolothuria(Halodeima)inornataSemper, 1868; the presence of the crab in the host’s coelomic cavity was confirmed, and for the first time we found it within the intestine. The geographical distribution is the Pacific coast of Mexico. Based on the data presented here, the taxonomic status ofHolothuriophilus trapeziformisis now complete.

Published: February 2022

Background

Animal models are significant for understanding human osteoarthritis (OA). This study compared the synovial fluid proteomics changes in surgical and chemical induced OA models.

Methods

Thirty rabbits either had anterior cruciate ligament transection (ACLT) procedure or injected intra-articularly with monosodium iodoacetate (MIA, 8 mg) into the right knee. The joints were anatomically assessed, and the synovial fluid proteins analyzed using two-dimensional polyacrylamide gel electrophoresis (2DGE) and MALDI TOF/TOF mass spectrometry analysis at 4, 8 and 12 weeks. The proteins’ upregulation and downregulation were compared with control healthy knees.

Results

Seven proteins (histidine-rich glycoprotein, beta-actin-like protein 2 isoform X1, retinol-binding protein-4, alpha-1-antiproteinase, gelsolin isoform, serotransferrin, immunoglobulin kappa-b4 chain-C-region) were significantly expressed by the surgical induction. They characterized cellular process (27%), organization of cellular components or biogenesis (27%), localization (27%) and biological regulation (18%), which related to synovitis, increased cellularity, and subsequently cartilage damage. Three proteins (apolipoprotein I-IV precursor, serpin peptidase inhibitor and haptoglobin precursor) were significantly modified by the chemical induction. They characterized stimulus responses (23%), immune responses (15%), biological regulations (15%), metabolism (15%), organization of cellular components or biogenesis (8%), cellular process (8%), biological adhesions (8%) and localization (8%), which related to chondrocytes glycolysis/death, neovascularization, subchondral bone necrosis/collapse and inflammation.

Conclusions

The surgical induced OA model showed a wider range of protein changes, which were most upregulated at week 12. The biological process proteins expressions showed the chemical induced joints had slower OA progression compared to surgical induced joints. The chemical induced OA joints showed early inflammatory changes, which later decreased.
Disentangling bias for non-destructive insect metabarcoding
Authors: Martoni Francesco , Piper Alexander M. , Rodoni Brendan C. , Blacket Mark J.
Published: February 2022

A fast and reliable method for obtaining a species-level identification is a fundamental requirement for a wide range of activities, from plant protection and invasive species management to biodiversity assessments and ecological studies. For insects, novel molecular techniques such as DNA metabarcoding have emerged as a rapid alternative to traditional morphological identification, reducing the dependence on limited taxonomic experts. Until recently, molecular techniques have required a destructive DNA extraction, precluding the possibility of preserving voucher specimens for future studies, or species descriptions. Here we paired insect metabarcoding with two recent non-destructive DNA extraction protocols, to obtain a rapid and high-throughput taxonomic identification of diverse insect taxa while retaining a physical voucher specimen. The aim of this work was to explore how non-destructive extraction protocols impact the semi-quantitative nature of metabarcoding, which alongside species presence/absence also provides a quantitative, but biased, representation of their relative abundances. By using a series of mock communities representing each stage of a typical metabarcoding workflow we were able to determine how different morphological (i.e., insect biomass and exoskeleton hardness) and molecular traits (i.e., primer mismatch and amplicon GC%), interact with different protocol steps to introduce quantitative bias into non-destructive metabarcoding results. We discuss the relevance of taxonomic bias to metabarcoding identification of insects and potential approaches to account for it.

Cerebral blood flow (CBF) monitoring is of great significance for treating and preventing strokes. However, there has not been a fully accepted method targeting continuous assessment in clinical practice. In this work, we built a noninvasive continuous assessment system for cerebral blood flow pulsation (CBFP) that is based on magnetic induction phase shift (MIPS) technology and designed a physical model of the middle cerebral artery (MCA). Physical experiments were carried out through different simulations of CBF states. Four healthy volunteers were enrolled to perform the MIPS and ECG synchronously monitoring trials. Then, the components of MIPS related to the blood supply level and CBFP were investigated by signal analysis in time and frequency domain, wavelet decomposition and band-pass filtering. The results show that the time-domain baseline of MIPS increases with blood supply level. A pulse signal was identified in the spectrum (0.2–2 Hz in 200–2,000 ml/h groups, respectively) of MIPS when the simulated blood flow rate was not zero. The pulsation frequency with different simulated blood flow rates is the same as the squeezing frequency of the feeding pump. Similar to pulse waves, the MIPS signals on four healthy volunteers all had periodic change trends with obvious peaks and valleys. Its frequency is close to that of the ECG signal and there is a certain time delay between them. These results indicate that the CBFP component can effectively be extracted from MIPS, through which different blood supply levels can be distinguished. This method has the potential to become a new solution for non-invasive and comprehensive monitoring of CBFP.
Role of Epigenetics in Developing Therapeutic Strategies against COVID-19

Epigenetics showcases an interconnection between genes and the environment. The expression or repression of genes can result from epigenetic regulatory mechanisms like Deoxyribonucleic Acid (DNA) methylation, histone modifications and chromatin remodelling. The Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) regulates host epigenetic machineries to mutate itself, improve its replication and increase its persistence by alienating the host's antigen-presenting molecules and modulating interferons expressing genes. The previous outbreak of Middle East Respiratory Syndrome Corona Virus (MERS-CoV) reveals that DNA methylation by the virus plays a crucial role in the loss of antigen-presenting molecules in the host. Since these coronaviruses share an ancestorial link, it is believed that the new coronavirus acts similarly. Recent reports of increasing morbidity, mortality and persistence of COVID-19 points to the rapid mutation and evading of immunity of the host. Vaccines, although they have helped to prevent the pandemic but their action remains questionable with new developing variants. We explore the possibility of developing epigenetic-based drugs and vaccines and other immune modulators that are being investigated to end the present COVID-19 pandemic and open new avenues for any such pandemics in the future. Comprehensive review regarding COVID-19 was obtained from PubMed and other search engines. Insights about the COVID-19 vaccines were reported from scientific sources. Epigenetics is a crucial subject to explore for the development of therapeutic strategies against the COVID-19 virus. Epigenetic modulators that can be re-programmed to counter the replication and infection efficiency of this virus and medications, including transcription suppressors, nucleoside inhibitors, can be one of the new strategies which may have a better outcome.

The current economic times demand that both men and women must get income to support their families. Women therefore have an additional responsibility of balancing between work life and family life. Therefore it was important to establish effect of work-life balance program on performance of women employees at horticultural sector in Kenya with a case of Uhuru Flowers Farms in Timau. The objective of the study was to establish how family responsibility affects performance of female employees. The research design employed was descriptive research design that helped describe the state of affairs of work-life balance at Uhuru Flowers. The target population for the study was 200 female employees employed at Uhuru Flowers. The sample size was 127 respondents selected using both stratified and simple random sampling. Data was collected by use of questionnaires. Results have been presented using frequency and percentage tables. Ethical issues were put into consideration which included seeking for permission from the organization and maintain confidentiality of the responds and win their trust. This study was supported by a budget of Kshs 220,000. The research findings indicate that family responsibility (p=0.005<0.05) significantly influences women employee performance in Uhuru flowers farms in Timau Kenya. The recommendations derived from the study is that management should also have a proper programme to ensure that women employees are able to address family issues accordingly since family responsibility significantly contributes to employee productivity.

Currently, data analysis literacy has attracted more and more attention from all walks of life. Many relevant problems about it have been studied except the cognitive degree of pre-service high school mathematics teachers on the implementation for data analysis literacy. In order to better implement the data analysis literacy in the process of middle school education, this study investigates the understanding of pre-service high school mathematics teachers on the implementation of data analysis literacy. This research design adopts the combination of quantitative and qualitative methods. 51 pre-service high school mathematics teachers from a university are selected through cluster sampling. Their cognition of implementing data analysis literacy is investigated through interview, and then the data are classified and coded by list method. It is found that: 1. The scope of cognition of the current pre-service high school mathematics teachers on the implementing for data analysis literacy is not wide, and more than half of the content on the implementing for data analysis literacy previously proposed has not been realized by many pre-service teachers yet; 2. The understanding focuses on that students should experience the whole process of data analysis; 3. The cognition of many pre-service teachers is not reasonable and lacks feasibility or effectiveness, which needs to be further explored and thought. Therefore, it is suggested that: 1. Experts and teachers responsible for training work should provide more teaching practice opportunities for pre-service teachers; 2. Pre-service teachers should pay attention to observing students' learning status in the process of practice, reflect on whether their cultivation strategies are reasonable, and then make further adjustments according to the actual situation of the school and classroom.

Aims: This study aims to analyze and assess the concept of forest management based on local wisdom and the implementation of the concept of forest management by Forest Commander based on local wisdom in North Aceh District. This activity is carried out by the Forest Institution's Customary Institution which has been confirmed in Aceh Regulation No.10 of 2008 concerning Customary Institutions.

Study design:  This research is an empirical legal research with a qualitative approach that uses primary data and secondary data. In obtaining primary data, respondents and informants were determined.

Place and Duration of Study: North Aceh, between June 2020 until May 2021

Methodology: This study uses empirical legal research with a qualitative approach using primary data and secondary data. In obtaining primary data, respondents and informants were determined.

Results: Forest management is carried out based on customary law as local wisdom in North Aceh. management is carried out by the Forest Commander as the head of the customary institution. However, the existence of the Forest Commander has not been maximized in implementing customary law. Ironically, this sub-district has a large area of ​​forest, and various regulations in the Aceh Government Law and Aceh Regulation have confirmed the existence of the Forest Commander.

Conclusion: The concept of forest management based on local wisdom existed in the people of North Aceh Regency in ancient times. Because, in customary forest law contains warnings such as which trees can be cut or not so that it does not cause disaster for the village.
