Published: January 2023

Background:Studies have shown that the lipid metabolism mediator leukotriene is associated with the pathogenesis of allergic rhinitis (AR). The aim of this study was to identify key lipid metabolism-related genes (LMRGs) related to the diagnosis and treatment of AR.
Material and methods: AR-related expression datasets (GSE75011, GSE46171) were downloaded through the Gene Expression Omnibus (GEO) database. First, weighted gene coexpression network analysis (WGCNA) was used to get AR-related genes (ARRGs). Next, between control and AR guoups in GSE75011, differentially expressed genes (DEGs) were screened, and DEGs were intersected with LMRGs to obtain lipid metabolism-related differentially expressed genes (LMR DEGs). Protein‒protein interaction (PPI) networks were constructed for these LMR DEGs. Hub genes were then identified through stress, radiality, closeness and edge percolated component (EPC) analysis and intersected with the ARRGs to obtain candidate genes. Biomarkers with diagnostic value were screened via receiver operating characteristic (ROC) curves.Differential immune cells screened between control and AR groups were then assessed for correlation with the diagnostic genes, and clinical correlation analysis and enrichment analysis were performed. Finally, reverse transcription-polymerase chain reaction(RT‒qPCR) was made on blood samples from control and AR patients to validate these identified diagnostic genes.
Results: 73 LMR DEGs were obtained, which were involved in biological processes such as metabolism of lipids and lipid biosynthetic processes. Sixty-six ARRGs and 22 hub genes were intersected to obtain four candidate genes. Three diagnostic genes (LPCAT1, SGPP1, SMARCD3) with diagnostic value were screened according to the AUC > 0.7, with markedly variant between control and AR groups. In addition, two immune cells, regulatory T cells (TReg) and T follicular helper cells (TFH), were marked variations between control and AR groups, and SMARCD3 was significantly associated with TFH. Moreover, SMARCD3 was relevant to immue-related pathways, and correlated significantly with clinical characteristics (age and sex). Finally, RT‒qPCR results indicated that changes in the expression of LPCAT1 and SMARCD3 between control and AR groups were consistent with the GSE75011 and GSE46171.
Conclusion: LPCAT1, SGPP1 and SMARCD3 might be used as biomarkers for AR.

Purpose
The diagnosis of sessile serrated lesions (SSL) and SSL with dysplasia (SSLD) using blue laser/light imaging (BLI) has not been well evaluated. We analyzed the diagnostic ability and specific endoscopic findings of BLI for SSL and SSLD compared to those of narrow band imaging (NBI).
Methods
We retrospectively reviewed 476 resected lesions from the cecum to the descending colon, which showing Type1 of the Japan NBI Expert Team (JNET) classification completely or partially with magnified NBI or BLI between 2014 and 2021 in our institution. The comparison of the NBI and BLI groups after matching was performed regarding the diagnostic ability of SSL and SSLD. The endoscopic findings of SSL on NBI and BLI were defined as expanded crypt opening (ECO) or thick and branched vessels (TBV) based on previous reports. Additionally, those of SSLD originally defined as network vessels (NV) and white dendritic change (WDC) were analyzed.
Results
After matching, the sensitivity of lesions with either ECO or TBV for diagnosing SSL and with those with either WDC or NV for diagnosing SSLD in the NBI/BLI were 97.5%/98.5% (p = 0.668) and 81.0%/88.9% (p = 0.667). Regarding the comparison of specific endoscopic findings between the SSLD and SSL, there were significant differences in WDC (66.4% vs. 8.6%, p < 0.001), NV (55.3% vs. 1.4%, p < 0.001), and either WDC or NV (86.8% vs. 9.0%, p < 0.001).
Conclusions
There was no difference in the diagnostic ability of NBI and BLI for SSL and SSLD. NV and WDC might be useful for diagnosing SSLD.
Primary adenoid cystic carcinoma in the lung: reporting a recurrent case at an advanced stage and mini-literature review.
Authors: Bendari Ahmed
Published: January 2023

Introduction: Primary adenoid cystic carcinoma (ACC) of the lung only account for less than 0.2% of all primary lung tumors. ACC in lung usually arises from the peribronchial glands and they are usually proximally located which makes it often challenging for surgical resection
Case presentation: A 65-year-old woman who was diagnosed with adenoid cystic carcinoma in 2017 at another institution and treated with lobectomy. In 2021, she presented at our hospital with frequent cough and dyspnea at rest and on exertion. Chest radiography showed bronchial obstruction and lung atelectasis, for stent placement for symptomatic relief. Repeated chest CT in 2022 showed progression of the tumor involving beyond the lung parenchyma into pleura and diaphragm Finally, the patient had left posterolateral thoracotomy, extra pleural pneumonectomy, En bloc pericardiectomy and En bloc resection of left diaphragm. Now she is on lung cancer surveillance with chest CT every 6 months. Last chest CT did not show any residual tumor or recurrence.
Conclusion: Despite its rarity, primary ACC of the lung should be well recognized by the pathologist and clinicians to make accurate diagnosis. . Although ACC of the lung usually has an indolent clinical course and behavior, recurrences are relatively frequent. The prognosis depends on the most dominant histological pattern, tumor staging and surgical margin status.
A core-shell electrospun scaffold including extracellular matrix and chitosan to promote articular cartilage tissue regeneration
Authors: Movahedi Mehdi , Karbasi Saeed
Published: January 2023

Electrospinning is known as a versatile technique for articular cartilage tissue regeneration (ACTR) due to its excellent potential to produce a fibrous scaffold that mimics the extracellular matrix (ECM) of native tissue. However, there is a need to promote the biological performance of scaffolds maintaining their mechanical strength. In this study, a core-shell polyhydroxybutyrate (PHB)-starch/halloysite nanotubes (HNTs) @ ECM-chitosan (Cs) scaffold was prepared via the coaxial electrospinning method. The results exhibited a narrower fiber diameter of up to 164 ± 24 nm with an appropriate pore size and porosity after incorporating Cs and ECM. Moreover, the core-shell scaffold showed an enhanced Young’s modulus up to 4.45 ± 0.1 MPa that could support chondrocyte cell growth. After that, the wettability and in vitro degradability of the core-shell scaffold were induced due to the hydrophilic nature of shell components. Also, chondrocyte cells had more viability and attachment on the core-shell structure proving the potential of core-shell fibers for biomedical applications. In conclusion, the results showed that the core-shell structured PHB-starch/HNTs @ ECM-Cs could be a suitable candidate for further trial towards ACTR.

Published: January 2023

The continuous advancement of modern technology enables its users to engage in various interactions in the online public sphere, including conversations about multiple ideas and perspectives. It has now played a significant role in our modern society, paving the door for several participatory cultures and social movements such as the so-called cancel culture. Even if this movement aims to call out individuals or businesses, it has undoubtedly encouraged mob mentality and damaged civil dialogue, ultimately driving them out of the community. Thus, this study looked at the diverse experiences of victims of cancel culture and how it influenced their social and personal lives. It reveals that the victims suffered a backlash, public humiliation, and cyberbullying that harmed their mental health. This study has established that cancel culture is an example of online abuse and has become more commonplace in the online public realm, rendering social media sites less of a safe haven.

Authors: dos Santos Brito Giovane , Maria de Sá e Silva da Cruz Osilene , Schenka Ribeiro Nayla
Published: January 2023

O processo de ensino e aprendizagem de Língua Portuguesa para surdos sempre foi alvo de profundas discussões. Com a oficialização da pandemia da COVID-19, em março de 2020, inúmeras transformações socioeconômicas e educacionais aconteceram no Brasil. Em decorrência do rápido contágio da doença, um distanciamento social foi imposto, provocando a mudança do ensino presencial para a modalidade remota. Este estudo objetivou analisar os discursos de discentes surdos do ensino superior sobre o ensino de Língua Portuguesa como Segunda Língua e as práticas docentes utilizadas nesse processo, utilizando os aportes teórico-metodológicos da Linguística Sistêmico-Funcional, desenvolvida por Halliday (1994), das legislações referentes à Educação de Surdos e das reflexões de Barbara e Macêdo (2010), Pereira (2014) e Fernandes (2008). A coleta de dados se deu pela análise das respostas de graduandos surdos do Brasil a um questionário bilíngue, encaminhado virtualmente. Trata-se de uma pesquisa descritiva, realizada sem o auxílio de softwares específicos do campo linguístico, sob a natureza quantiqualitativa, considerando a metafunção ideacional da teoria-base do estudo, reconhecendo três representações distintas sobre o ensino e aprendizagem da Língua Portuguesa como Segunda Língua para surdos. Concluiu-se que as práticas didático-metodológicas realizadas na educação de surdos continuaram a desconsiderar cultura, identidades e especificidades linguísticas desses sujeitos.
Ophthalmic Manifestations, Evaluation, and Guidelines for Testing of Concussion
Authors: Shteyman Amy , DeBroff Brian M
Published: January 2023

Early detection and treatment of concussions is crucial to preventing further brain damage. Current subjective standard-of-care tests used to diagnose concussions, such as symptom reporting and standardized concussion checklists, can often underdiagnose patients with concussions. This review will cover novel biomarkers of concussions related to concussion-associated visual deficits and how they can be used to more accurately monitor patient concussion symptom improvement. Visual deficits are seen in up to 90% of patients within hours after a concussion-inducing trauma and can serve as objective biomarkers in diagnosing and monitoring concussions. Some of the key visual deficits that are seen in patients with concussions include convergence insufficiency, problems with accommodation and smooth pursuit eye movements, saccade dysfunction, and decreased optokinetic nystagmus gain. Patients frequently report blurred vision, challenges reading, double vision and eyestrain, dizziness, visual field defects, and light sensitivity, related to concussions. Promising eye tests to detect and track concussions include pupillary light reflexes, the circle test, and the Samandarani group’s non-spatially calibrated binocular motility test/algorithm in conjunction with video oculography and eye tracking equipment. The EYE-SYNC eye-tracking device allows for portable and accurate detection of eye movements in the field and is a promising tool for detecting concussions both in the field and clinic. Optical coherence tomography and other retinal imaging modalities also represent a promising method of identifying individuals who have sustained a concussion.
Effect of Driver Response on Efficiency of Vehicular Communication using Penalty Cost Function (EVCPCF)
Authors: Iskandarani Mahmoud Zaki
Published: January 2023

Background and Objective:

This study examines and takes into account three key timing factors that have an impact on the effectiveness of human-machine interfaces (HVI). A threshold-based mechanism is created to account for both cooperative driving and advanced vehicle control system (AVCS) scenarios. For AVCS and cooperative driving, the developed model takes into account on-board machine interface time, human interface time, and transmission time.

Methods:

A threshold function that represents the penalty cost of a slow driver reaction is presented in order to enable adaptive intelligence, enhance HVI design, and increase vehicle safety. The Penalty Cost Function (PCF) is used to make vehicle control systems intervene and take control in situations where the driver responds slowly to safety and warning messages. Additionally, this study demonstrates that AVCS-based vehicular systems are more responsive overall and are less impacted by the PCF function than cooperative systems.

Results:

The mathematical models created through this work allowed for a limiting efficiency value and capping for each driving scenario, according to comparative plots. This will improve the creation of more reliable control systems as part of a vehicle's mechatronics, impacting how vehicles communicate with one another in a cooperative setting. MATLAB simulation was used to verify the mathematical model. The simulation covered two limiting cases of 0.33 and 0.5 and used incrementing numbers of vehicles (10, 20, 30, 40, 50) to check the impact of increasing vehicle numbers on communication efficiency and examine whether both AVCS and AVCS with cooperative will have close levels and converge at limiting values.

Conclusion:

The successfully completed simulation demonstrated that throughput decreased as the number of vehicles increased, although in the limiting case, both scenarios and the driving system changed virtually by the same percentage.

Authors: Kermavnar Tjaša , Visch Valentijn T , Desmet Pieter M A
Published: January 2023

Background

The COVID-19 pandemic introduced an urgent need for effective strategies to disseminate crucial knowledge and improve people’s subjective well-being. Complementing more conventional approaches to knowledge dissemination, game-based interventions were developed to create awareness and educate people about the pandemic, hoping to change their attitudes and behavior.

Objective

This study provided an overview and analysis of digital and analog game-based interventions in the context of the COVID-19 pandemic. As major pandemics and other large-scale disruptive events are expected to increase in frequency in the coming decades, this analysis aimed to inform the design, uptake, and effects of similar future interventions.

Methods

From November 2021 to April 2022, Scopus, Google, and YouTube were searched for articles and videos describing COVID-19–themed game-based interventions. Information regarding authorship, year of development or launch, country of origin, license, deployment, genre or type, target audience, player interaction, in-game goal, and intended transfer effects was extracted. Information regarding intervention effectiveness was retrieved where possible.

Results

A diverse assortment of 23 analog and 43 digital serious games was identified, approximately one-third of them (25/66, 38%) through scientific articles. Most of these games were developed by research institutions in 2020 (13/66, 20%) and originated in Europe and North America (38/66, 58%). A limited number (20/66, 30%) were tested on relatively small samples, using a diversity of research methods to assess the potential changes in participants’ knowledge, attitudes, and behaviors as well as their gameplay experience. Although most of the evaluated games (11/20, 55%) effectively engaged and motivated the players, increased awareness, and improved their understanding of COVID-19–related issues, the games’ success in influencing people’s behavior was often unclear or limited.

Conclusions

To increase the impact of similar future interventions aimed at disseminating knowledge and influencing people’s attitudes and behaviors during a large-scale crisis, some considerations are suggested. On the basis of the study results and informed by existing game theories, recommendations are made in relation to game development, deployment, and distribution; game users, design, and use; game design terminology; and effectiveness testing for serious games.

Published: January 2023

Abstract: Mobile Ad hoc Network is a network in which numerous are contained. These nodes are dynamic in nature and utilize multi-hop communication for communicating with one another. There isn’t any central controller included in such a network. These nodes have random mobility and they are allowed to move in any direction due to the infrastructure less quality of this network. DFCP is a routing algorithm using which a path can be established amid source and target. The link failure leads to mitigate the efficacy of this protocol whose enhancement is required for maintaining the QoS. This research work suggests the enhancement of DFCP algorithm to recover the path when the link is failed. NS2 is applied to deploy the suggested algorithm. The simulation outcomes exhibit that the suggested algorithm outperformed the traditional methods concerning higher throughput and lower packet loss.

The Threshold Level of Economic Growth in BRI and Non-BRI Developing Countries for Better Environmental Quality
Authors: Kon Yee-Qin , Chin Mui-Yin , Ong Sheue-Li
Published: January 2023

This study investigates the nexus between economic growth and carbon dioxide (CO2) emissions. Specifically, this study employs a dynamic panel threshold model to identify and compare the threshold levels of economic growth between developing countries participating and not participating in the Belt and Road Initiative (BRI). The findings signify a nonlinear relationship between the sampled countries’ economic growth and their CO2 emissions in both categories. Furthermore, the result of dynamic panel threshold model reveals that the threshold level of economic growth, in the category of BRI developing countries, was lower (US$ 887.49) as compared to non-BRI developing countries (US$ 1358.57). This implies that the impact of economic growth in developing countries participating in the BRI was less harmful to the environment, and that these countries are more alert to environmental issues once the threshold of their gross domestic product per capita was achieved. Hence, Chinese authorities should put in more effort in facilitating sustainable infrastructure development to attract more developing countries to join the BRI to mitigate environmental degradation.

This study aims to analyse the market structure, conduct, and performance of the star hotel industry in North Sumatra. The study was conducted in 2019 with time series data for the period of 2013 to 2018. The market structure is measured using the methods of concentration ratio, Herfindahl-Hirschman index, and barriers to entry, while descriptive methods are used to analyse the conduct and performance of five-star hotels. The results of the study show that: (i) there is a concentration of three- and four-star hotels, and that the concentration of four- and five-star hotels have an oligopolistic structure; (ii) the market structure of star hotels tends to be monopolistic; (iii) the minimum efficient scale index of star hotels is relatively small, which means that new hotels have a good opportunity to get a larger market share; (iv) the level of service and the level of availability of star hotel facilities are classified as good; and (v) the star hotel market structure influences hotel business behaviour in North Sumatra, which in turn affects hotel business performance.
Annam Mata cha Brahma Remembering Amma(mother) Through the Kongu Food Culture
Authors: Maya Maya , Shabin Shabin
Published: January 2023

Perumal Murugan is an acclaimed Indian novelist, essayist and poet who writes in Tamil language. He has been hailed by audiences and connoisseurs alike for his excellent storytelling, attention to detail and representation of the brutal realities of the rural agrarian communities of Kongu Nadu Despite the whirlpool of controversies and threats that surrounded Murugan’s life and writings, nothing has deluded him from the path of being a committed writer determined to use writing as a weapon to expose the societal inconsistencies. The present interview revolves around the role of food in his creative works. It includes a discussion of the various culinary traditions and food paradigms of his ancestral village, the reverence for food and environment amongst agrarian communities, the difference that food preferences create amongst people, and the entry of the fast-food culture due to globalization. Along with his other literary works, the interview also briefly discusses his memoir Amma, where Murugan recollects the cherished food memories of his childhood and also of his mother whose values and love for cooking have shaped both his identity and culinary preferences. Murugan’s penning or narrativizing of these memories through various creative forums has assisted in what David Sutton calls as “prospective memory” (163) aiding the process of how people plan to remember meals and how tasty they would be.
Underground Nuclear Testing: The Leading Cause of Global Warming
Authors: Hansen Clay
Published: January 2023

This paper aims to document a scientific linkage between the underground
testing of nuclear weapons and global warming. An empirical analysis of
CO2 and fossil- fuel data post-1945 suggests that global warming is not
clearly attributable to greenhouse gas emissions alone. Our data
indicates beyond statistical doubt a direct linkage between the rise in
CO2 levels and underground bomb testing; rendering adverse consequences
like global warming, radioactive contamination of terrestrial and marine
ecosystems, and major disruptions to temperature patterns around the
world. The derivative carbon footprint of underground nuclear testing is
colossal and can bring about devastating human-induced climate changes
which are not just massive but potentially irreversible.
The basic features of typical consumers of organic food
Authors: Mitic Vladimir , Colovic Milica
Published: January 2023

The major goal of current research is to determine the general frequency of
buying organic food and the elementary demographic features of a typical
consumer of organic food. Six hundred participants of different genders,
ages, levels of education, material and marital statuses, incomes and living
areas were comprised. A Google questionnaire was used, in the period from
June to December 2021, and it was sent to 800 people, out of whom 600 people
filled out the questionnaire completely. The metric characteristics of the
applied questionnaire were, as in previous researches in which this
instrument was used, at an appropriate level. SPSS version 26 was used for
data processing and analysis. Nonparametric techniques have been used due to
the irregular distribution of scores on the measured variables. Descriptive
statistics was used to adequately present the sample, and the Mann-Whitney U
test and the Kruskal-Wallis test were employed to detect the existing
differences between the groups of participants. It has been shown that the
frequency of buying organic food in Serbia is still at a very low level.
Classic customers of organic food are mostly older women with higher

The current study is performed to identify the flow regimes of oil-gas two-phase flow experimentally in a vertical pipe has an internal diameter of 6.7 cm. It also aims to provide more details about the possibility of using Differential Pressure Transducers (DPT) for indicating flow patterns. A flow development of oil and gas has been investigated in a vertical pipe of 6 m in length and operated at atmospheric pressure. A series of experiments have been run to cover a range of inlet oil superficial velocities from 0.262 to 0.419 m/s, and inlet gas superficial velocities from 0.05 to 4.7 m/s. Wire Mesh Sensors (WMS) have been used to collect the obtained void fraction values of the flow. The Differential Pressure Transducer (DPT) is utilized to measure the pressure drop values of a one-meter along the pipe. The flow patterns are classified according to the analysis of void fractions, pressure gradients regarding time series, tomographic images, probability density functions of the void fractions, and pressure gradients. A bubbly flow is observed at low superficial velocities of gas and liquid, slug flow is observed at the lower flow rate of liquid and moderate flow rates of gas, while the churn flow pattern is recognized at the higher rates of liquid and gas. Also, the result has revealed the possibility of using Differential Pressure Transducers (DPT) to classify the gas-oil flow patterns in vertical pipes.

Cities in Jordan, especially the capital, Amman, are witnessing traffic jams due to the increase in the number of cars and the increase in population (whether it is a natural increase or an increase due to successive migrations from the neighboring countries). This study aims to evaluate and improve the level of service (LOS) and delay of the Elba-house intersection in Amman city, Jordan. The required data were collected from the governorate traffic departments and also directly from the field. The intersection was evaluated using SIDRA INTERSECTION 5.1 software. The results show that the level of service is F, and the intersection is crowded with a total delay time of about 285.8 seconds. A tunnel in addition to a roundabout was proposed to decrease the average delay and increase its level of service. The reanalysis of the intersection provided good results whereas the level of service can be increased to B and the average delay reduced to 13.3 seconds.

Authors: Tontini Julia , Sarturi Greici , Stocker Fabricio
Published: January 2023

Objetivo: Este estudo tem como objetivo analisar a relação entre distribuição de valor e a satisfação dos funcionários.
Referencial Teórico: A pesquisa utiliza como lente teórica a teoria dos stakeholders, abordando o conceito de valor e seu impacto no contexto organizacional. Utilizou-se o modelo de valor desenvolvido por Harrison e Wicks (2013).
Método: A coleta de dados foi realizada por meio de um questionário, aplicado em 32 funcionários de uma empresa do setor de agribusiness. Para análise dos dados, foi empregada a técnica de regressão linear simples e múltipla pelo método dos Mínimos Quadrados Ordinários (MQO).
Originalidade/Relevância: Este estudo avança na discussão sobre distribuição de valor para os stakeholders e apresenta uma nova relação de mediação entre valor e satisfação dos funcionários.
Resultados: Os resultados indicaram que a variável mais relacionada a satisfação com a empresa é a afiliação, ou seja, quanto mais os funcionários identificam-se com os valores da empresa, maior é a sua satisfação para com ela. Em seguida está a utilidade associada aos custos de oportunidade, destacando que quanto mais os colaboradores percebem ter feito um bom negócio em trabalhar na empresa, em relação aos concorrentes, mais esta pessoa está satisfeita.
Contribuições teóricas/metodológicas: Esta pesquisa apresenta duas contribuições. Primeiro, este estudo contribui para a teoria dos stakeholders ao testar empiricamente o Modelo de Harrison e Wicks (2013) e a relação da distribuição de valor com a satisfação do grupo de stakeholders funcionários. Em segundo lugar, apresenta-se evidências de uma relação de mediação entre os tipos de valor indicados no modelo e a satisfação do funcionário.
Contribuições sociais/para a gestão: O estudo também é importante para os gestores, à medida que orienta acerca de quais valores podem ser mais importantes para a satisfação do grupo de stakeholders funcionário.

Authors: Dias Regina
Published: January 2023

Este artigo tem como objetivo investigar as trajetórias escolares e a prática docente de professoras pertencentes às camadas populares que atuam na educação infantil e nos primeiros anos do ensino fundamental. Procurar-se-á refletir, com base na análise de memoriais acadêmicos elaborados em 2009 por um grupo de alunas-professoras do último período do curso Normal Superior, acerca da formação escolar e da prática docente desses sujeitos. Devido ao espaço restrito deste artigo e à abrangência da temática, neste trabalho será descrita e analisada especialmente a trajetória escolar narrada por uma dessas professoras. Utilizou-se no estudo uma abordagem biográfica. Assiste-se, nos últimos anos, a um aumento no número de docentes oriundos dessas camadas sociais. O trabalho pretende contribuir para que possamos compreender melhor quem são essas professoras, suas particularidades. Acredita-se que tal conhecimento seja fundamental para orientar nossas práticas como formadores de docentes e repensar a estrutura curricular dos cursos que formam esses profissionais da educação.

Peranan Echinodermata di perairan laut adalah sebagai pembersih limbah dan sampah, mempunyai nilai ekonomis tinggi. Echinodermata mempunyai cara dan kemampuan berbeda dalam menentukan lokasi yang cocok untuk tempat hidupnya, sehingga perbandingan jenis dan kelimpahan Echinodermata di suatu lokasi pada waktu yang berbeda perlu untuk dipelajari. Penelitian ini bertujuan untuk mengetahui struktur komunitas Echinodermata di Pulau Barrang Lompo Kecamatan Ujung Tanah Kota Makassar. Penelitian ini bersifat deskriptif. Pengambilan sampel dilakukan di tiga titik stasiun yaitu stasiun I (Zona lamun), stasiun II (Zona berpasir), dan stasiun III (Zona karang). Penelitian ini dilakukan pada bulan Februari 2016, dengan menggunakan metode transek kuadran. Parameter yang diukur meliputi parameter fisika (temperatur), parameter kimia (pH, salinitas, DO), dan parameter biologi (keanekaragaman dan kelimpahan Echinodermata). Dari hasil penelitian pada tiga tiga titik stasiun ditemukan 11 jenis Echinodermata dalam empat kelas yaitu Asteroidea, Holothuroidea, Echinoidea, dan Ophiuroidea dengan indeks keanekaragaman (H’) tergolong rendah (nilai 0,9), indeks keseragaman populasi (e) rendah (0,3), dan indeks dominansi (C) menunjukkan ada jenis/kelas yang mendominasi (0,5).
