Background: Occupational therapy (OT) cognitive interventions requires a standardised cognitive outcome measure to help explain the effectiveness of the interventions. Now, there is a lack of measures to use for Thai older adults with cognitive impairments. Therefore, a new Occupational Therapy Cognitive Outcome Measure (OTCOM) for Thai older adults with cognitive impairments was developed to support evidence-based OT cognitive interventions. Objectives: To examine the psychometric properties including internal consistency, inter-rater and intra-rater reliability, known-group construct validity, concurrent validity, and responsiveness of the OTCOM. Materials and methods: A prospective cohort design was used in this study. One hundred and ten older adults; sixty-one older adults with cognitive impairments and forty-nine older adults without cognitive impairments, were recruited. The Cronbach’s alpha coefficient was calculated for internal consistency. Intraclass correlation coefficient (ICC) was used to analyse rater reliability. Analyses of concurrent and known-group construct validity were done using Pearson correlation and independent t-test, respectively. Both effect size (ES) and standardised response mean (SRM) were calculated for responsiveness of the OTCOM. Results: The results showed good internal consistency (α=0.88), and excellent inter-rater and intra-rater reliability (ICC=0.99). A high correlation between the OTCOM and the Dynamic Lowenstein Occupational Therapy Cognitive Assessment-Geriatric (DLOTCA-G) and the Thai Cognitive-Perceptual Test (Thai-CPT) was found, indicating good concurrent validity. There was a significant difference between older adults with cognitive impairments and without cognitive impairments, suggesting good construct validity by the known-group method. Responsiveness was shown as large ES and SRM in the total score. Conclusion: The OTCOM showed good psychometric properties, making it useful in OT practice after revisions

Background: Brain multi-detector computed tomography (MDCT) is commonly performed for diagnosis of traumatic or non-traumatic brain injury cases. During brain CT scan, the eye lens is highly sensitive to radiation and may cause radiation-induced cataracts irradiated by CT primary beam. Objectives: This study aimed to determine and compare entrance surface air kerma (ESAK) to the eye lens in clinical routine head protocols between 32-MDCT and 64-MDCT using an anthropomorphic phantom. Materials and methods: A PBU-60 head phantom was scanned by 32-MDCT and 64-MDCT in helical, axial, and tilted axial modes used in clinical routine head protocols with tube voltage of 120 kVp, tube current of 108-150 mAs for 32-MDCT, and 200-310 mAs for 64-MDCT. The NanodotTM optically stimulated luminescent dosimeters (OSLDs) was used to measure ESAK to eye lens. Dose length product (DLP), normalized volume CT dose index (nCTDIvol), and normalized mean ESAK were compared between two CT scanners. Results: The ranges of mean normalized ESAK to the eye lens in each scanning mode was found from 0.41±0.01 to 0.51±0.01 mGy/100 mAs for 32-MDCT and 0.30±0.01 to 0.40±0.01 mGy/100 mAs for 64-MDCT. The normalized ESAKs obtained from 64-MDCT were lower than 32-MDCT by 21.57-37.50%. The lowest normalized ESAK of 0.30±0.01 mGy/100 mAs was obtained in tilted axial scanning mode in 64-MDCT with the difference of 37.50% compared to 32-MDCT of using identical scanning mode. Conclusion: This study demonstrated that normalized mean ESAK to the eye lens for 64-MDCT in all brain scanning protocols was lower compared to 32-MDCT. In addition, using tilting gantry in axial scanning mode as well as using an automatic tube current modulation system could be beneficial for reducing radiation dose to eye lens during brain CT in clinical routine
PEDAGOGIA DO MST: UMA CONSTRUÇÃO COM A PRESENÇA DE PAULO FREIRE
Authors: Baldo Ana Maria , Garcia Elisete Enir Bernardi
Published: March 2022

O presente artigo, de natureza bibliográfica, excerto de dissertação de Mestrado em desenvolvimento, visa analisar a presença da perspectiva freireana na pedagogia do Movimento dos Trabalhadores e Trabalhadoras Rurais Sem Terra - MST. Nas análises parciais que obtivemos, podemos perceber que a pedagogia do MST está fundamentada, em sua maior parte, por esta perspectiva. A experiência do Movimento Sem Terra com sua pedagogia nos mostra caminhos viáveis e concretos para uma educação voltada para a transformação social e a emancipação humana. Freire deixou um forte legado para a construção da pedagogia do MST, sendo um de seus maiores inspiradores. O MST reconhece ter herdado de Freire características importantes de sua pedagogia, bem como, tem em Freire, além de um inspirador, um companheiro de luta; há uma relação de reciprocidade de afeto e conhecimentos trocados por ambos.
ORGANIZAÇÃO E FUNCIONAMENTO DE CONSELHOS ESCOLARES EM REDE MUNICIPAL DE ENSINO: LIMITES E POSSIBILIDADES
Authors: De Queiroz Silva Soares Carolina , Martins Angela Maria
Published: March 2022

Este artigo apresenta e discute ações encetadas na organização e no funcionamento do Conselho Escolar de unidades escolares da rede municipal de ensino de Poá, cidade localizada na Região Metropolitana da Grande São Paulo. Trata-se de pesquisa qualitativa tendo como procedimentos a análise documental e a realização de entrevistas semiestruturadas com equipes de gestão. Os resultados evidenciaram que apesar de os profissionais reconhecerem o papel do CE na efetivação da gestão democrática da escola, não foi possível identificar sua relevância na implementação e avaliação de atividades pedagógicas, limitando-se a tratar de assuntos financeiros e burocráticos. Nesse cenário, faz-se necessário instituir espaços coletivos de discussão no âmbito das escolas, para que professores e equipes de gestão aprimorem seu conhecimento acerca da indivisibilidade de questões administrativas, financeiras, logísticas e pedagógicas.

Published: March 2022

O ano de 2020 foi interrompido pela pandemia do coronavírus, quando abruptamente universidades, escolas, comércio e serviços não essenciais foram paralisados. Neste contexto adverso foi criado o projeto “A COVID 19 e a determinação social da saúde”. Uma pesquisa qualitativa, com enfoque na estratégia do diagnóstico participativo, que buscou discutir com a comunidade de uma escola pública federal, localizada em Niterói/RJ, sobre as condições de saúde e vulnerabilidade social impactadas pela pandemia, provocando reflexões e ações sobre as iniquidades em saúde. Neste artigo descrevemos as ações desenvolvidas pelos bolsistas deste projeto, analisando seus desdobramentos sob a luz da teoria da determinação social da saúde e da educação popular em saúde. Apesar das limitações impostas pelo distanciamento social, conseguimos dialogar virtualmente com a comunidade através das ações do projeto, promovendo discussões e reflexões importantes para o fortalecimento mútuo, contra todo tipo de ataque que insiste em aprofundar as desigualdades sociais.
SOBRE (RE)APRENDER A DO-DISCÊNCIA COM AS CRIANÇAS: UM DESAFIO VIVIDO COM AS TURMAS MULTI-IDADES DA UNIDADE DE EDUCAÇÃO INFANTIL IPÊ AMARELO/UFSM
Authors: Goelzer Juliana , Ilgo Henz Celso
Published: March 2022

Neste artigo apresentamos alguns dos constructos de uma pesquisa realizada com professoras de turmas multi-idades da Unidade de Educação Infantil Ipê Amarelo, uma Unidade da Universidade Federal de Santa Maria/RS, que teve o objetivo de investigar os possíveis desafios que a escuta sensível e o olhar aguçado às crianças nessas turmas provocam para os processos auto(trans)formativos com as professoras. O percurso metodológico, orientado pela Pesquisa-auto(trans)formação, foi realizado a partir de Cartas Pedagógicas e de Círculos Dialógicos Investigativo-auto(trans)formativos realizados com onze professoras que atuaram/atuam nessas turmas. Os constructos apontam que um dos maiores desafios auto(trans)formativos enfrentados por essas professoras foi o de reelaborar o olhar acerca da criança e de (re)aprender a do-discência (FREIRE, 1995) com elas, tendo em vista que, ao longo da formação inicial, segundo essas professoras, pouco se pensava em construir uma professora que aprende com as crianças.

Authors: Galhardo Oliva Sanches Beatriz , Gemignani Peterossi Helena , Avella Ramirez Rodrigo
Published: March 2022

A Educação Profissional, mais especificamente a de nível médio integrada à modalidade de Educação de Jovens e Adultos (EJA), é um campo marcado pela falta de regularidade, carente de estudos em que muitas questões surgem e se fazem necessárias. Neste cenário, o presente trabalho surgiu como uma reflexão sobre a Educação Profissional e Tecnológica, o papel dos docentes e da escola na formação dos sujeitos tendo em vista seus marcos legais em nosso país, em especial as iniciativas e programas para o Ensino Técnico Integrado ao Médio na modalidade EJA, no contexto do Centro Paula Souza. Outro aspecto examinado é a percepção discente sobre o componente curricular “Língua Portuguesa, Literatura e Comunicação Profissional” proposto no itinerário formativo em questão. Assim, este artigo pretende analisar a experiência de uma Escola Técnica Estadual para investigar como os alunos percebem a importância da disciplina e sobre como compreendem a aquisição das habilidades linguísticas.

Knowledge brokering organisations: a new way of governing evidence
Authors: MacKillop Eleanor , Downe James
Published: March 2022

Background:

Government-funded knowledge brokering organisations (KBOs) are an increasingly prevalent yet under-researched area. Working in the space between knowledge and policy, yet framing themselves as different from think tanks and academic research centres, these organisations broker evidence into policy.

Aims and objectives:

This article examines how three organisations on different continents develop similar narratives and strategies to attempt to inform policymaking and build legitimacy.

Methods:

Using documentary analysis and semi-structured interviews, it shows how the organisations construct their credibility and legitimacy, and make sense of their emergence, activities and relationships with policymakers.

Findings:

The study responds to the lack of political focus on many existing studies, examining how KBOs make sense of their origins and roles, articulating notions of evidence, and mobilising different types of legitimacies to do so. The research also addresses an empirical gap surrounding the emergence and activities of KBOs (not individuals), analysing organisations on three different continents.

Discussion and conclusions:

KBOs developed similar narratives of origins and functions, despite emerging in different contexts. Furthermore, they build their legitimacy/ies in similar ways. Our research improves our understanding of how a new ‘tool’ in the evidence-informed policymaking (EIPM) arsenal – KBOs – is being mobilised by different governments in similar ways.
Modeling nonlinear high-pressure sensors based on degenerate four-wave mixing in photonic crystal fibers
Authors: Nallusamy Nagarajan , Arzate N. , Vasantha Jayakantha Raja R. , Singhal Rahul
Published: March 2022

We propose a high-pressure sensing mechanism in solid-core silica photonic crystal fibers (PCF) that is based on the nonlinear optical process of degenerate four-wave mixing. A quite simple configuration for the pressure sensor is given and is theoretically investigated by obtaining signal gain spectra. We focus on the Stokes and anti-Stokes sidebands that are generated during propagation of the field along the PCF due to the interplay of dispersion and nonlinear optical effects. We have considered wave propagation in the normal dispersion regime with the inclusion of negative fourth-order dispersion. We have also considered a pumping field with wavelength of 1076 nm and peak power of 3000 W that propagates along a PCF with 40 cm of length. We have optimized sensitivity, varying lattice pitch and air-hole diameter, and we have obtained high sensitivities of the Stokes and anti-Stokes lines of 3.672 and

Soiling induced nano-defects on aluminum telescope mirror coatings
Authors: Willers Guido , Hagendorf Christian , Naumann Volker , Holzlöhner Ronald , Guisard Stéphane
Published: March 2022

Airborne contaminations on telescope mirrors are an important issue that is significantly affecting their reflectance, IR emissivity, and light scattering properties. Microscopic damage caused by environmental contaminants is of major interest for high-performance telescope mirror coatings. We have exposed unprotected Al coated mirrors under real operation conditions at the Very Large Telescope on Cerro Paranal/Chile for three years. The unique finding is that, in spite of a dry and low-dust environment, the reflective layers are damaged by interaction between dust particles on the Al mirror surface and capillary condensation. We analyze this particular damage mechanism at the microstructural level.
Anti-mutation load and error stability of a large aperture lens based on parallel collimation locking
Authors: Zhang Donghui , Zhang Chao , Liu Zhigang , Zheng Liunian , Pang Xiangyang , Zhu Jianqiang
Published: March 2022

Based on the lens of spatial filter parallel auxiliary assembly and collimation method, aiming at the unloading and locking problem of the filter lens after collimating, a lens parallel adjustable axial locking structure was proposed. A special elastic chuck structure was designed to realize clamping axial friction locking; each branch realized interference fit, and the adjustable structure of “line-line-line” contact realized equivalent fixation through spring pre-tightening. Compared with radial locking, the abrupt error of the axial locking lens in the unloading process of a collimating auxiliary machine was small, and the posture state maintenance and structural response stability were strong. The established homogeneous transformation matrix (HTM) and lens global error showed that the pose torsion roll error of the radial locking structure was significantly suppressed. The relative stability experiment showed that the angular drift error of the lens axial locking structure was ± 0.2 µrad. The design effectively improved the unloading anti-mutation characteristics and stability of the filter lens, which provided an experimental basis for the application of intelligent collimation assisted assembly and adjustment scheme in the upgrading of a high-power laser device.

Pulse rate multiplier based on the temporal Talbot effect in birefringent optical filters
Authors: Driouche Youcef , Hamdi Rachid , Graini Leila , Halassi Abderezzaq , Benkelfat Badr-Eddine
Published: March 2022

In this paper, we propose a novel approach to implement a pulse rate multiplier based on the temporal self-imaging effect using, for the first time to our knowledge, a birefringent optical filter. The proposed filter, with periodic quadratic phase-only filtering induced through engineered polarization mode dispersion, contains

N

-stage hybrid birefringent crystals set between an input polarizer and an analyzer. Each stage is composed of an identical section and a variable section. An optimization algorithm is used to determine the opto-geometrical parameters of the filter. Preliminary results for 10-stage, 12-stage, 16-stage, and 20-stage birefringent filters show very high fidelity for multiplying a 10 GHz input pulse rate by factors of two, four, six, and eight, respectively, without distorting the individual pulse properties.
Damping of relaxation oscillations, photon-photon resonance, and tolerance to external optical feedback of III-V/SiN hybrid lasers with a dispersive narrow band mirror
Authors: Rimoldi Cristina , Columbo Lorenzo Luigi , Bovington Jock , Romero-García Sebastian , Gioannini Mariangela
Published: March 2022

We address the stability of a tunable hybrid laser based on a III-V Reflective Semiconductor Optical Amplifier (RSOA) edge-coupled with a Silicon Photonic (SiPh) dispersive mirror through a model of time-delayed algebraic differential equations that accounts for the narrow band mirror. Our results allow to (i) analyze the stability of single mode lasing, (ii) quantify the impact of the mirror bandwidth on the damping of the laser relaxation oscillations and the emergence of photon-photon resonance, and (iii) study the tolerance of the laser to the external optical feedback. Thanks to this analysis, we find a mirror design that gives ultra-high stability up to an external feedback level of −10 dB. The aim of the work is providing a tool for understanding and interpreting the dynamics of these lasers and design configurations for isolator-free operation.

Published: March 2022

An Er:Yb:Ba3Gd(PO4)3 crystal was grown by the Czochralski method. Spectral properties of the crystal associated with 1.5–1.6 µm laser operation were investigated, including the absorption and fluorescence spectra and the fluorescence decay at room temperature. The fluorescence quantum efficiency of the 4I13/2 level of Er3+ ions and energy transfer efficiency from Yb3+ to Er3+ ions were calculated. A CW diode-pumped Er:Yb:Ba3Gd(PO4)3 laser at 1.5–1.6 µm with output power of about 73.9 mW and slope efficiency of 16.3% was achieved for the first time in the Er3+/Yb3+ co-doped phosphate crystal.
Don’t you tweet me badly: Anxiety contagion between leaders and followers in computer-mediated communication during COVID-19
Authors: Gruda Dritjon , Ojo Adegboyega , Psychogios Alexandros
Published: March 2022

Do organizational leaders’ tweets influence their employees’ anxiety? And if so, have employees become more susceptible to their leader’s social media communications during the COVID-19 pandemic? Based on emotional contagion and using machine learning algorithms to track anxiety and personality traits of 197 leaders and 958 followers across 79 organizations over 316 days, we find that during the pandemic leaders’ tweets do influence follower state anxiety. In addition, followers of trait anxious leaders seem somewhat protected by sudden spikes in leader state anxiety, while followers of less trait anxious leaders are most affected by increased leader state anxiety. Multi-day lagged regressions showcase that this effect is stronger post-onset of the COVID-19 pandemic compared to the pre-pandemic crisis context.
Régimen y paráfrasis: sobre el tratamiento lexicográfico de las colocaciones verbonominales
Authors: Pérez Benavente Pablo
Published: March 2022

La Teoría Sentido-Texto (TST) integra las colocaciones en el diccionario mediante funciones léxicas, un lenguaje formal que recoge de forma sistemática este tipo de expresiones e informa, aunque solo de manera parcial, sobre su combinatoria. Esta información se incluye en todas las entradas lexicográficas, por lo que el uso de funciones léxicas puede entenderse como una consecuencia del estatuto ambiguo de las colocaciones, a medio camino entre el frasema y la combinatoria libre. En ocasiones es imposible predecir completamente la combinatoria sintáctica de una colocación más allá de lo incluido en la propia fórmula de la función léxica. En un diccionario que se pretende exhaustivo, como el empleado en la TST, esta información es importante no solo para un correcto procesamiento y producción de textos (el principal enfoque de la TST), sino también para la paráfrasis (otro de los puntos fuertes del modelo). El presente trabajo intenta aportar diversas ideas a esta reflexión a partir de un conjunto de colocaciones verbonominales pertenecientes a dos campos semánticos de comportamiento dispar: el de los golpes y el de los sentimientos. En primer lugar, se ha realizado un análisis sintáctico-semántico de los regímenes de las colocaciones y sus verbos plenos equivalentes siguiendo el modelo lingüístico de la TST. A continuación, se han comparado ambas combinatorias con el objetivo de asegurar la máxima fidelidad en el proceso de sustitución por paráfrasis. Finalmente, se han recogido diversos instrumentos lexicográficos, coherentes con la estructura del diccionario empleado en la TST, que tratan de describir el comportamiento observado en el análisis, complementado con mecanismos que ponen en comunicación unas secciones del diccionario con otras. Estos dispositivos mixtos permitirían la caracterización precisa de las colocaciones sin que sea necesario el tratamiento particularizado de cada expresión como si se tratase de unidades léxicas plenas.

Background Acute kidney injury (AKI) is an underrecognized complication of severe malaria and an independent risk factor for mortality among children.

Objective To determine the incidence and factors predictive of AKI as defined by the pediatric risk, injury, failure, loss, and end-stage (pRIFLE) criteria in children with severe malaria and to assess in-hospital mortality rates in malarial AKI (MAKI).

Methods This was a prospective cohort study in 170 children aged 0.5 to 14 years with confirmed Plasmodium falciparum on peripheral blood smears and clinical and/or laboratory features of severe malaria. Serum creatinine was determined using the Jaffe method and glomerular filtration rate (eGFR) was estimated using the Schwartz equation. The primary outcome was the incidence of AKI as defined by the pRIFLE criteria. Secondary outcomes included in-hospital mortality comparison between AKI and non-AKI groups, as well as factors predictive of AKI.

Results The incidence of MAKI was 61.2% (104/170) and was comparable between males (66.7%) and females (70.6%). Mean eGFR was lower among children with AKI than those without [42.00 (SD 22) vs. 98.7 (SD 3.9) mL/min/1.73m2, respectively; P=0.005]. Children with MAKI were categorized as having risk (47/104; 45.2%), injury (33/104; 31.7%), or failure (24/104; 23.1%). Mortality rates in AKI and non-AKI subjects were comparable (4.8% vs. 4.6%; P=0.888). Predictors of MAKI were hemoglobinuria [adjusted OR (aOR) 3.948; 95%CI 1.138 to 8.030], deep acidotic breathing (aOR 2.991; 95%CI 3.549 to 66.898), and longer hospital stay (aOR 2.042; 95%CI 3.617 to 12.156). Children with MAKI were more likely to have a longer hospital stay by a mean of 2.5 days.

Conclusion AKI is a common complication in children with severe malaria. MAKI has a low mortality rate comparable to those with severe malaria but without AKI.  Hemoglobinuria, deep acidotic breathing, and longer hospital stay were predictive of MAKI.

Authors: Mangunatmadja Irawan , Fauziyah Ricca , Rafli Achmad
Published: March 2022

Encephalitis is a neurological disorder that develops rapidly into a progressive encephalopathy caused by inflammatory processes in the brain. The incidence of encephalitis in developed countries is 5-10 per 100,000 per year. Encephalitis can affect all ages and cause long-term effects on patients, their families, and society.1-3 Autoimmune encephalitis, including anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, is increasingly recognized as a cause of encephalitis in children and has a considerable mortality rate of 5-7%.4  Physicians should suspect anti-NMDAR encephalitis in patients with prominent neuropsychiatric symptoms and movement disorder.1-3 We report here a case of anti-NMDAR encephalitis and discuss the role of clinical criteria in diagnosing anti-NMDAR encephalitis in children.

In object-oriented information extraction from high-resolution remote sensing images, the segmentation and classification of images involves considerable manual participation, which limits the development of automation and intelligence for these purposes. Based on the multi-scale segmentation
strategy and case-based reasoning, a new method for extracting high-resolution remote sensing image information by fully using the image and nonimage features of the case object is proposed. Feature selection and weight learning are used to construct a multi-level and multi-layer case library
model of surface cover classification reasoning. Combined with image mask technology, this method is applied to extract surface cover classification information from remote sensing images using different sensors, time, and regions. Finally, through evaluation of the extraction and recognition
rates, the accuracy and effectiveness of this method was verified.

This article proposes an estimation method for assessing urban sprawl using multispectral remote sensing data: SNPP-VIIRS, DMSP/OLS, Landsat 5-TM, and Landsat 8-OLI. This study focuses on the impacts of human activities, in terms of increased electrical-power consumption (EPC) due to
urbanization. For this purpose, night-time light data are used to measure the EPC growth from 2000 to 2020. We also perform a suitability analysis using geographic information-systems techniques to propose a new urban town in Lahore to mitigate urbanization and EPC increase. We found an overall
increase of 33% in urban area and an EPC increase of 21.6% in the last two decades. We also find that the best proposed site for the new urban town is in the northwest of Lahore.

Computed tomographic coronary artery calcium scanning enables cardiovascular risk stratification; however, exposing patients to high radiation levels is an ongoing concern. New-generation computed tomographic systems use lower radiation doses than older systems do. To quantify comparative doses of radiation exposure, we prospectively acquired images from 220 patients with use of a 64-slice GE LightSpeed VCT scanner (control group, n=110) and a 256-slice GE Revolution scanner (study group, n=110). The groups were matched for age, sex, and body mass index; statistical analysis included t tests and linear regression.

The mean dose-length product was 21% lower in the study group than in the control group (60.2 ± 27 vs 75.9 ± 22.6 mGy·cm; P <0.001) and also in each body mass index subgroup. Similarly, the mean effective radiation dose was 21% lower in the study group (0.84 ± 0.38 vs 1.06 ± 0.32 mSv) and lower in each weight subgroup. After adjustment for sex, women in the study group had a lower dose-length product (50.4 ± 23.4 vs 64.7 ± 27.6 mGy·cm) than men did and received a lower effective dose (0.7 ± 0.32 vs 0.9 ± 0.38 mSv) (P=0.009). As body mass index and waist circumference increased, so did doses for both scanners.

Our study group was exposed to radiation doses lower than the previously determined standard of 1 mSv, even after adjustment for body mass index and waist circumference. In 256-slice scanning for coronary artery calcium, radiation doses are now similar to those in lung cancer screening and mammography.

Gastropoda adalah salah satu biota yang dapat berasosiasi dengan lamun. Kondisi padang lamun pada kedua lokasi akan mempengaruhi tingkat kerapatan dan kelimpahan biota yang berada di perairan. Penelitian ini bertujuan untuk mengetahui tingkat kerapatan lamun yang berbeda dan kelimpahan gastropoda serta hubungan antara tingkat kerapatan lamun yang berbeda dengan kelimpahan gastropoda. Pelaksanaan penelitian ini dilakukan pada bulan Mei dan Agustus 2020 di Perairan Teluk Awur dan Pulau Panjang, Jepara. Metode yang digunakan dalam penelitian ini adalah studi kasus yang bersifat deskriptif berdasarkan 3 kerapatan yang berbeda, yaitu kerapatan jarang, sedang, dan padat. Hasil penelitian menunjukkan terdapat 4 jenis lamun di Perairan Teluk Awur dan 5 jenis lamun di Perairan Pulau Panjang, yaitu Enhalus acoroides, Thalassia hempricii, Cymodocea serrulata dan Cymodocea rotundata dan Halophila ovalis. Kelimpahan gastropoda di kerapatan lamun jarang, sedang, dan padat di Teluk Awur adalah 67,5 ind/m², 97 ind/m² dan 10,5 ind/m², sedangkan kelimpahan gastropoda di kerapatan lamun jarang, sedang, dan padat di Pulau Panjang adalah 96 ind/m², 97,5 ind/m² dan 336,5 ind/m². Berdasarkan hasil regeresi menunjukkan antara kelimpahan gastropoda dengan kerapatan lamun terdapat korelasi yang erat, sehingga semakin tinggi kerapatan lamun akan diikuti oleh tingginya kelimpahan gastropoda. Seagrass beds are one of the marine ecosystems located in coastal areas and have an important role in the waters. Gastropods are one of the biota associated with seagrass beds. The conditions of the seagrass beds in both locations will affect the density and abundance of biota in the waters. This study aims to determine the different levels of seagrass density and abundance of gastropods and the relationship between different seagrass density levels and the abundance of gastropods. This research was carried out in May and August 2020 in the waters of Teluk Awur and Panjang Island, Jepara. The method used in this research is a descriptive case study based on 3 different densities, namely rare, medium, and dense. The research steps taken were sampling, identification, data analysis and data evaluation. The results showed that there were 4 types of seagrass in Teluk Awur  waters and 5 types of seagrass in Panjang Island waters, namely Enhalus acoroides, Thalassia hempricii, Cymodocea serrulata and Cymodocea rotundata and Halophila ovalis. The abundance of gastropods in the rare, medium, and dense seagrass density in Awur 67,5 ind/m², 97 ind/m² dan 10,5 ind/m², while the abundance of gastropods in the rare, medium and dense seagrass density in Panjang Island was 96 ind/m², 97,5 ind/m² dan 336,5 ind/m². Based on the regression results, there is a strong correlation between gastropod abundance and seagrass density, so that the higher the seagrass density will be followed by the higher gastropod abundance.
