Authors: Lokman Rackmawatie , Daud Sity , Hoo Chiew Ping
Published: October 2022

South Asia’s international relations dilemma is not mainly about power struggles among the regional states but also includes the significant presence of major powers. This article analyses the factors leading to South Asia’s geopolitical challenges, serving the role of regional powers with their strategic allies, notably the US and China that appear to influence the region’s stability. Based on findings from unstructured interviews with experts and research on China-Pakistan’s extending relations in CPEC, this article contends that the phenomenon may potentially bolster power rivalry in South Asia, particularly between India and Pakistan. Against this backdrop, states may be involved in power struggles, whether through band wagoning or hedging, among themselves or with other major powers for their strategic interests. Thus, this article aims to discuss the CPEC’s impacts on South Asia’s geopolitical orientation, serving power rivalry among the actors in the region. Two major arguments are discussed, namely, (1) South Asia’s international relations and (2) External Powers’ Rivalry.
Merapatkan Jurang Pemahaman Konsep Tenaga antara Ahli Fizik dan Pelajar Fizik Sekolah Menengah
Authors: Ispal Azlinah , Ishak Mohd. Zaki
Published: October 2022

Menurut sejarah, istilah tenaga sudah lama diguna pakai dalam perbualan harian untuk menjelaskan aktiviti yang berkaitan dengan kemampuan melakukan kerja, tetapi istilah ini tidak semestinya boleh digunakan dalam semua bidang. Kajian lepas menunjukkan terdapat pelbagai konsep pengetahuan alternatif terpahat dalam minda pelajar yang mungkin sama atau bertentangan dengan pemahaman saintifik ahli fizik. Oleh itu, penyelidikan yang berteraskan tradisi pendidikan Jerman-Didaktik telah dijalankan. Menurut tradisi ini guru mesti “mengelementarisasikan” isi kandungan pengetahuan fizik dan menyepadukannya dengan konsep pengetahuan alternatif pelajar untuk melaksanakan PDPC yang berkesan. Penyelidikan ini dijalankan untuk memahami bagaimana jurang pemahaman konsep tenaga antara ahli fizik dan pelajar fizik sekolah menengah boleh dirapatkan dengan menggunakan Model Pembinaan Semula PdPC (MPSP). Oleh itu, penyelidik telah meneliti 15 penerbitan utama untuk menentukan pemahaman saintifik ahli fizik tentang tenaga, menjalankan temu bual separa berstruktur melibatkan 12 orang pelajar fizik sekolah menengah untuk mencari konsep pengetahuan alternatif tenaga mereka dan menganalisis semula 23 kajian terdahulu yang berkaitan dengan isu yang sama. Kaedah analisis kualitatif kandungan dan analisis metafora digunakan untuk membantu penyelidik merungkai makna yang tersurat dan tersirat di sebalik bahasa fizik mahupun bahasa perbualan harian yang mengandungi konsep tenaga, dan bagaimana bahasa-bahasa ini saling berinteraksi. Dapatan kajian diwakili oleh laluan pembelajaran yang menghubungkan konsep fizik berorientasikan aktiviti harian dan fizik. Laluan pembelajaran ini memaparkan jurang pemahaman antara ahli fizik dan pelajar fizik sekolah menengah dan bagaimana mereka berkait antara satu sama lain.
The Emergence and Development of Split Log Coffins in South Korea during the Iron Age
Authors:   Yeongnam Archaeological Review, Oh Kang Won
Published: October 2022

The split log coffin burial in South Korea is largely divided into seven stages. Stage I(250~200 B.C.) featured an attached-round rim vessel and a bronze implement; Stage II(199~100 B.C.) a type Ⅰ rectangular cast-iron axe; Stage III(101~50 B.C.) an attached-triangular rim vessel, a type-II rectangular cast-iron axe, a type-I lozenge cast-iron axe, and a type-I rectangular flat iron axe; Stage IV(49 B.C.~1 A.D.) a nascent soft gray pottery, a type-II and type-III rectangular cast-iron axe, a type-II lozenge cast-iron axe, a type-II rectangular flat iron axe, and a type-II short lozenge flat iron axe; Stage V(1~50 A.D.) a type-III rectangular cast-iron axe, a type-III lozenge cast-iron axe, and a type-II long lozenge flat iron axe; Stage VI(51~100 A.D.) a type-III long lozenge flat iron axe; Stage VII(101~150 A.D.) the latest type of a gray pottery in the early period, etc.
The split log coffin burial in South Korea arose in the context of South Korea on its own. It is thought that only beliefs and rituals for old big trees and big trees existed from late the first half of the Bronze Age to the first half of the Songgugni type culture, and that there were rituals for big trees(立大木) in the second half of the Songgugni type culture or in the first half of the slender bronze dagger type culture. It is also thought that returning to the Daegok-ri type culture, the creative chiefdom stratification of the Daegok-ri group that dominated the bronze implement technology occurred as old big trees and big trees were converted to split log coffins. Split log coffins generated in the inland area of Jeollanam-do were distributed in the Man-kyung river basin and Gyeonggi region before 100 B.C. Since then, they spread to the eastern part of South Korea which later became the core part of their distribution, and they became extinct according to the change of burial concept before and after 150 A.D.
O Sujeito Pronominal De Primeira Pessoa Em Revistas Da Turma Da Mônica: Uma Análise Em Tempo Real De Curta Duração
Authors: Amorim Zanellato Carolina
Published: October 2022

No presente estudo, buscamos observar, por meio de uma análise em tempo real de curta duração, a variação da expressão do sujeito pronominal de primeira pessoa em revistas da Turma da Mônica em três sincronias distintas: década de 1970, década de 1990 e década de 2010. No português brasileiro, essa variável pode aparecer de duas formas: preenchida (“Como eu gostaria que a humanidade perdesse o olfato”) e nula (“ø Vamos voltar pro céu!”). Utilizamos como base teórica a Sociolinguística Variacionista (LABOV, 2008 [1972]) e os trabalhos de Duarte (1993 [2018]) e Silva (2004), que trazem resultados distintos para o fenômeno. Os resultados mostram uma estagnação na mudança do sujeito pronominal em direção ao preenchimento, que se mantém acima de 50% nas três sincronias: 66,5% em 1970; 52,8% em 1990 e 54,2% em 2010, o que prova que o PB ainda possui parâmetro pro-drop parcial.
Performance of dredged sediments based controlled low-strength material
Authors: SOLANKİ Pranshoo
Published: October 2022

The process of depleting the natural sources of virgin sand and aggregate makes it challenging to satisfy the demand for construction work. Therefore, in a context of sustainable construction, this study examined the feasibility of utilizing dredged sediments (DS) as a substitute for sand in non-structural controlled low-strength materials (CLSM). A total of two types of dredged sediments, coarser and finer, were collected from two different sources. Then, nine CLSM mixtures were prepared by using different proportions of natural sand (virgin sand) and dredged sediments. Each mixture was tested for flowability, unconfined compressive strength, density and excavatability. Flow consistency decreased with the amount of dredged sediments and presence of finer material in CLSM. Strength results were found within required specification for all nine CLSM tested in this study. Overall, flow consistency, strength and excavatability were found dependent on the characteristics of dredged sediments. This study showed that dredged sediments can be successfully used as a sand substitute for CLSM production.

Authors: BAYSAL Ataberk , YAYLA Paşa , TÜRKMEN Halit Süleyman
Published: October 2022

Fiber-reinforced polymer composites are well-studied and established products and today they are being used in different industrial and non-industrial areas. However, the increased interest in recyclability and the concerns about climate change caused materials scientists to look for a non-petroleum-based alternative to synthetic fibers and polymers. Since the beginning of this century, natural fibers and biopolymers have seen an increased interest each year for composite applications. Thanks to this interest, the studies on natural fibers and biopolymers have increased significantly. Despite the high number of studies on natural fibers and natural fiber-reinforced polymers (NFRP), there are gaps in the literature. This work reviews the studies on natural fibers, biopolymers, and biocomposites with their advantages, disadvantages, and limitations. The studies that focus on the ways to reduce or eliminate these disadvantages and limitations have also been looked at. Also, current challenges and future perspectives for natural fibers, biopolymers, and NFRPs have been discussed
An Evaluation of Vertical Dynamic Stress Attenuation for Compacted Coarse-Grained Soils
Authors: SUN Kuangbiao , FANG Mingjing , SHU Donglin , PU Yang , WANG Wenbing
Published: October 2022

Coarse-grained soil (CGS), as a filler with the characteristics of high bearing capacity but difficult compaction for embankment construction, requires an appropriate thickness of a single compaction layer according to the influence depth of vertical dynamic stress. In this paper, a numerical analysis using PFC2D was conducted by following a scale model test with different particle gradations of compacted CGS fillers by adopting a modified PFWD. The results show that the influence depth is about 50 cm under the impact maximum stress 0.066 MPa if defined the depth as the maximum stress attenuation to 20%. The compacted CGS filler with the dense particle gradation and high strength has a rapid attenuation on vertical dynamic stress. Meanwhile, with the increase of stone content (P5, particle size ≥5 mm), the vertical dynamic stress of compacted CGS is attenuated exponentially. The maximum particle size also affects the attenuation of vertical dynamic stress, which needs further research. The findings support the development of non-destructive devices to rapidly inspect the compactness of subgrade construction.

Published: October 2022

Recently, it is known that carbon fiber, which is a conductive fiber, is used in different mixture designs and developing electrically conductive cementitious materials. However, the evaluation of ferrochrome as a recycled aggregate in the mixture of these special concretes has still not been investigated. In this study, electrically conductive mortars were produced by using 100% recycled ferrochrome aggregate with a particle size of less than 1 mm as filling material and using carbon fiber (CF) in 4 different ratios, 0%, 0.5%, 0.75% and 1%. 2, 14, 28, 90 and 180 days electrical resistivity properties of the obtained samples were investigated. In addition, 28-day compressive strength, flexural strength, dynamic resonance, ultrasonic pulse velocity (UPV), Leeb hardness, scanning electron microscope (SEM) and X-Ray Diffraction (XRD) tests were performed on all samples. The obtained results were compared with the literature and it was proved that ferrochrome can be used as a reasonable aggregate in conductive mortars.
DIGITALIZATION AND FINANCIAL INCLUSION IN AFRICA
Authors: FIGUET Jean-Marc , KERE Asrafil Safilidin
Published: October 2022

The ineffectiveness of economic development policies over the past few years has been largely due to the exclusion of the population from participating in wealth creation. This is probably the main source of income inequality. To remedy this problem and bridge the gap, technological innovation and financial digitalization are effective tools for development actors. This paper aims to assess the impact of the digitalization of financial services on financial inclusion using panel data from 48 African countries over the 2011- 2017 period. Our results show that mobile money and digital payments have a positive and significant impact on bank account penetration, access to credit and savings mobilization. However, the digital inclusion process is hampered in many countries by the dearth of Internet servers, the lack of infrastructure and lengthy administrative procedures.
HFTS AND NON-HFTS ALONG THE LIMIT ORDER BOOK
Authors: Beardsley Xiaoxin W. , He Zheng
Published: October 2022

Using NASDAQ high frequency trading and limit order book data over 120 stocks between 2008 and 2010, we document that HFTs are active in order placement along the book with an average placement at the 5th step, slightly ahead of NHFTs. HFT orders are further ahead during market crisis, though price-wise they retreat. Liquidity provider in trades, not consumer, matters in order placement along the book. Traders becomes more (less) aggressive placing orders when their own (the other) kind provides liquidity in trading. Trades between HFTs (NHFTs) are significantly related with less aggressive orders from NHFTs (HFTs) along the book.

Published: October 2022

A male 16.9m fin whale (Balaenoptera physalus) was stranded on 3 April 2019 at Chanduy southwestern Ecuador (2°23’29.4” S, 80°44’17.96” W). Its coloration pattern, including the white-colored right side of the mouth and around 200 cream-colored baleens, are characteristics of the species. This is the first confirmed record of the species in almost a century in mainland Ecuador. A skin sample was taken for molecular studies. Fragments of the D-loop and CytB mitochondrial genes were amplified and compared with global databases. The D-loop fragment matched with a haplotype found in a fin whale from the Central-south of Chile and the CytB with several populations in both hemispheres. Our findings confirm that the Ecuadorian coast is part of the distribution area of southeastern Pacific fin whales.

Authors: Siaw Gladys Apreh
Published: October 2022

Purpose: Despite evidences that training helps improve health and safety practices in hotels, there is modicum of knowledge of how being a Technical and Vocational Education and Training-trained housekeeper influences health and safety practices in hotels in Central Region, particularly Cape Coast and Elmina. This study, in response to this gap, examined the effect of being a TVET-trained housekeeper on health and safety practices in hotels in Cape Coast and Elmina.

Methodology: The explanatory research design was employed. Data were collected, using self-administered questionnaire, from 100 conveniently selected housekeepers of 51 hotels in Cape Coast and Elmina in the Central Region. Data collected were analysed using means, standard deviations and regression analysis.

Findings: The results showed that seven dimensions account for about 60% of the variance in health and safety practices. Also, the general level of health and safety practices in hotels in Cape Coast and Elmina was high – with higher average scores recorded among TVET-trained housekeepers compared to non-TVET-trained housekeepers. Additionally, the study revealed a statistically significant positive effect of being a TVET-trained housekeeper on health and safety practices in hotels.

Recommendation: It was recommended that for improved health and safety practices in the hotels in Cape Coast and Elmina, there is the need for TVET-trained housekeepers; thus, hotel operators should give preference to employing TVET-trained housekeepers.

FOLLOW-UP PROCEDURES FOR CRIMES OF ABUSE OF AUTHORITY IN ALGERIAN LEGISLATION
Authors: BOUAMRA Brahim , HAFDALLAH Abdellali
Published: October 2022

The abuse of authority is considered one of the most serious crimes due to the consequent waste of rights and freedoms, as well as the fact that it constitutes a serious violation of the integrity of the job that represents the public of state authorities and agencies, and based on this, the Algerian legislator criminalized the abuse of power represented in violating the sanctity of the home, and the crimes of abstinence It also approved a number of punitive and procedural texts to punish the perpetrators of this crime, where the public official in the abuse of power constitutes the main axis of its establishment along with the purpose of the pillars. To be criminal, disciplinary, or civil. Thus, the Algerian legislator tried to reduce the crime of abuse of authority by referring the job with punitive rules to the employees so that they would object to them performing the work entrusted to them to the fullest without any manipulation that could undermine the citizen’s confidence in the state and its structures. There is a link between the committed crime and the work of their job. They are responsible for these crimes, and a number of legal measures are taken against them that the legislator monitors by virtue of the status or capacity they hold, So that the authority authorized to carry out these legal procedures must respect and apply them to the fullest extent in order to avoid any violation of individual rights and freedoms. Accordingly, the legislator has listed a set of penal and disciplinary measures for the public servant that must be followed during his follow-up. Accordingly, this study highlights its importance in that the crimes of abuse of authority are among the serious crimes that conflict with the integrity of the public office and lead to violating the rights and freedoms of individuals, and it may reach the point of disturbing public order and harming the public interest. As for the problem posed by this research paper, it revolves around a fundamental question: To what extent is the Algerian legislator in line with limiting the crimes of abuse of authority through the monitored follow-up procedures? Accordingly, this study aims at a set of objectives, to be summarized in clarifying the basis for criminalizing the abuse of authority, and to identify the forms of the crime of abuse of authority and the follow-up procedures monitored for it through the Algerian legislation. In order to answer the problem posed, a methodological approach was followed that relies on the analytical method by analyzing the relevant legal texts.
THE PROBLEM OF THE RELATION SHIP BETWEEN PRONUNCIATION AND MEANING IN THE ISLAMIC RHETORIC FIELD
Authors: LAROUSSI Nadia
Published: October 2022

This research aims to shed light on the problem of the relationship of the word with the meaning in the Islamic rhetoric field, because it is the basic epistemological linguistic problem that occupied the forefront in the rhetoric cognitive system, and it has worked to crystallize it since the era of codification, as this dilemma was a subject of dispute among scholars with their various references in the deliberative Islamic field, but in the history of mankind as a whole, which extends through times and epochs, this problem was raised in the Greek era by the poles of Greek philosophy as an integral part of the study of ontology, as the philosophy of language that concerned itself with language in its general and abstract concept was not a self-contained philosophy for them. Pioneers of Greek philosophy who are credited with developing linguistic and logical studies. It has been associated with Islamic thinkers, especially among jurists, with understanding the Qur’anic text and determining its true and intended meaning, which requires that the truth matches between human understanding or human knowledge on the one hand and the intended divine meaning expressed in the Qur’anic text on the other hand. They defend it against the anti-Islam sects, as they add to this problem a metaphysical dimension, which is organically related to the issue of "creating the Qur'an", and it was not confined to linguistics and forensic sciences only, Rather, it was strongly present among the logical philosophers who were influenced by Greek philosophy to the point of fascination, and the positions of the rhetoricians differed according to their different starting points.

Published: October 2022

The crystals of pure and L-Proline doped Potassium nitrate and Sodium nitrate were grown in solution by slow evaporation technique using supersaturated solution of the salts. Characterization studies of the crystals have been done to find the impact of the L-Proline on the regular lattice arrangement of the pure crystal. The Powder XRD spectrum reveals that the pure and doped KNO3 crystals belong to orthorhombic structure; and pure and doped NaNO3 are rhombohedral in nature. This is a unit cell with parameters a = b = c; α = β = γ ≠ 90°. There are small changes in the unit cell dimensions but the structure of the pure and doped crystals remain to be orthorhombic in nature. The FTIR spectrum shows the functional group analysis of the samples. The various decomposition process of the crystals with respect to temperature have been carried out in thermal analysis. The dielectric properties exhibit the variation of dielectric constant, and capacitance with frequency at various temperatures for pure and doped crystals. The doped crystals found to have considerable effect on the optical, thermal and dielectric properties.

HIGHLIGHTS

Effect of dopant L-Proline on the growth of Potassium nitrate and Sodium nitrate crystals by solution growth was carried out for the first time

The studies based on dielectric properties and thermal analysis gives a broad understanding about the influence of the dopant on the pure crystals

Variation of dielectric constant, resistance, and capacitance with respect to frequency at various temperatures reveals that the dopant L-Proline has a significant effect

Authors: Sudsila Pupe , Thongteeraparp Ampai , Aryuyuen Sirinapa , Bodhisuwan Winai
Published: October 2022

The Topp-Leone (TL) distribution is introduced by Topp and Leone [1]. Its probability density function is a simple function with only one parameter. Even though the TL distribution has been discussed and applied in many research fields, but there is a limitation about its shape. In this article, we propose the T-TL family of distributions using quantile function of  family of distributions to generate generalized TL distributions including the Weibull-TL{exponential}, the log-logistic-TL{exponential}, the logistic-TL{extreme value}, the exponential-TL{log-logistic} and the normal-TL{logistic} distributions. Some associated properties and inferences are discussed. Some graphical representations related to the probability density function are shown. Finally, 3 real datasets are applied to illustrate the generalized TL distributions.

HIGHLIGHTS

The Topp-Leone distribution is introduced in 1955. Its probability density function is a simple function with only one parameter. It has been discussed and applied in many research fields

The T-Topp-Leone family of distributions using quantile function of family of distributions to generate generalized Topp-Leone distributions including the Weibull-Topp-Leone{exponential}, the log-logistic-Topp-Leone{exponential}, the logistic-Topp-Leone{extreme value}, the exponential-Topp-Leone{log-logistic} and the normal-Topp-Leone{logistic} distributions

Some statistical properties, such as reliability function, hazard function, quantile function of T-Topp-Leone family, Shannon entropy, moments, mean deviation and median deviation are discussed

All generalized Topp-Leone distributions are applied to three real datasets and the results indicated that five distributions obtained from the new family can be used as good alternatives to the Topp-Leone, beta and Kumaraswamy distributions

Published: October 2022

High-impact practices (HIPs) have been adopted by many universities around the world to enhance student learning. The aim of this qualitative study was to analyzed how building ePortfolios may impact student learning experience via weekly reflections. A total of 47 senior undergraduate English as a foreign language (EFL) students enrolled in research projects shared reflections about their research experiences via the development of ePortfolios. Data analysis was carried out through deductive coding of the transcribed focus groups and weekly reflections. Findings suggest that the participants used their ePortfolios to improve their writing skills and increase their knowledge. Students were able to track their progress and felt more engaged in learning. They also showed appreciation to the feedback provided by their instructors on their reflections. However, the students shared some challenges they faced while developing their ePortfolios. Despite these challenges, there was a positive impact of ePortfolios on students’ learning experiences. Implications and further directions for research are discussed.

Authors: Memon Atia Bano , Memon Shakeel Ahmed
Published: October 2022

The present paper deals with designing a criteria catalog for the definition and characterization of academic innovation facilities established within premises of higher education institutes. The in-depth content analysis of available scientific literature on the topic and web description of existing innovation facilities from their official websites is carried out following a purposive observational approach. As a result, a criteria catalog of 12 aspects including 6 functional and 6 structural aspects along with their possible field configurations is devised and proposed herein. The proposed catalog should assist in defining a particular innovation facility in more standardized manner and thereby serve as a guideline for planning and establishing new academic innovation facilities. The catalog should also enable to cross-compare and distinguish multiple innovation facilities across different geographies in order to reveal their relative strengths and weaknesses.
Clinical Characteristics and Outcome of Infants with Biliary Atresia in Bahrain
Authors: Isa Hasan M. , Irshad Zainab
Published: October 2022

Objectives: Though the prevalence of biliary atresia (BA) in the Middle East is low, its role in causing life-threatening liver diseases is disproportionately high. This study aimed to assess the prevalence, clinical presentations, diagnosis, surgical interventions, and long-term outcomes including survival rate, and to analyze prognostic factors affecting the survival of infants with BA in Bahrain. Methods: A retrospective cohort review of cases of infants diagnosed with BA between January 1993 and December 2021 at Salmaniya Medical Complex, Bahrain, was conducted. Demographic, clinical, laboratory, imaging, and histopathological data were analyzed. Outcomes measured included 5-year native liver survival (NLS) and overall liver survival (OLS) rates. Results: Out of 27 infants diagnosed with BA, 26 were included in the study. The overall prevalence was 0.007% and was significantly higher among Bahraini (0.006%) compared to the non-Bahraini population (0.001%), p< 0.001. Most patients had clay-colored stool (19 of 22; 86.4%) and hepatomegaly (18; 81.8%). Kasai procedure was performed in 23 (88.5%) patients and primary liver transplant (LT) in three. Ten (38.5%) infants required LT after the Kasai procedure. The median age at diagnosis was 56 days with interquartile range (IQR) of 30–90, and the median age at the Kasai procedure was 61 days (IQR = 56–90). NLS and OLS rates were 53.8% and 65.4%, respectively. The overall mortality rate was 34.6%. Six of the 13 (46.2%) patients who were subjected to Kasai procedure alone died awaiting LT donors. Infants with lower birth weight and older age at diagnosis had significantly better odds of survival (p< 0.029 and p< 0.044, respectively). Conclusions: BA is uncommon among infants in Bahrain. Despite effective treatment options, late diagnosis can lead to significant morbidity and mortality. Our study found a relatively low prevalence of NLS (53.8%) and OLS (65.4%). Since the majority of the diagnosed patients had presented with clay-colored stools, implementing an infant stool card for screening may be beneficial in raising parental awareness and detecting BA early. Early detection and treatment using novel therapies are likely to improve the survival rates.

Esse entendimento e a maneira como os professores concebem opções para enfrentar tensões e contradições da prática educativa, visando à garantia do direito à educação, recorrentemente, configuram objeto de estudo e compromisso político-pedagógico da Didática no contexto das disputas de classes nos limites do capitalismo, mediadas pela educação escolar. No Brasil, a crise política, agravada pela pandemia da covid-19, revelou retrocessos significativos. Na Educação, tal circunstância toma conformação nas contrarreformas curriculares, na afirmação do neotecnicismo pedagógico e na atuação marcante das tecnologias na escolarização. Objetiva-se problematizar os influxos dessa realidade no trabalho didático do professor, seus rebatimentos na efetivação do direito à educação, na organização do ensino e na docência. Reporta-se à análise teórica sustentada por formulações vinculadas a uma Didática crítica e intercultural. Questiona-se: Como pensar o trabalho didático do professor no contexto contemporâneo, caracterizado por tantos retrocessos? Quais as possibilidadesda Didática contribuir paraa interlocução do fazer docente com a formação,considerando a atual disputa no concerto da prática educativa?

Purpose

Although assessment of the orbital structures using magnetic resonance imaging (MRI) is well described in the literature, there is no consensus as to which measurement method is the most useful in exophthalmos assessment. The aim of the study was to correlate 2 MRI methods of exophthalmos measurement with exophthalmometry results and to determine a proper technique of exophthalmos measurement.

Material and methods

Fifty-four patients (108 orbits) with exophthalmos in the course of Graves’ orbitopathy were enrolled in the study. Two measurements on axial T2W orbital MRI images were performed by 2 independent radiologists: the distance from the interzygomatic line to the anterior surface of the globe (AD) and the distance from the interzygomatic line to the posterior sclera (PD). Within 4 weeks, an exophthalmometry was performed by an ophthalmologist using a Hertel exophthalmometer. The inter-observer variation was assessed using the Pearson correlation coefficient. Values were presented as mean and standard deviation, and the differences in values were explored with Student’s t-test.

Results

The mean AD measured on MRI by the first observer was 20.6 ± 3 mm, and 20.6 ± 2.9 mm by the second observer. PD values were 2.9 ± 2.8 mm and 3.4 ± 2.8 mm, respectively. The mean exophthalmometry result was 21 ± 3.3 mm. The correlation was very high between observers for AD measurements (r = 0.98, p = 0.01) and high for PD measurements (r = 0.95, p = 0.01). AD measurements on MRI and exophthalmometry results were strongly correlated (r = 0.9, p = 0.01).

Conclusions

The AD measurement has better reproducibility and is directly correlated with Hertel exophthalmometry. This method could be sufficient in routine practice.
