Published: July 2021

Purpose:

To evaluate medication and follow-up adherence in incarcerated patients examined at an academic glaucoma clinic, in comparison to nonincarcerated controls.

Methods:

Retrospective, case-control study. Consecutive prisoners presenting for initial visits in the Glaucoma Clinic at the Illinois Eye and Ear Infirmary between December 2015 and December 2017 were included in the study. Nonincarcerated patients seen in the same Glaucoma Clinic with similar initial visit dates, age, race, sex, and disease severity were selected as controls. Glaucoma Clinic visits from each patient were reviewed until December 2018. Examination information, surgical intervention, follow-up and treatment recommendations, and patient-reported medication usage were recorded for each visit. Number of visits, loss to follow-up, follow-up delays, and medication nonadherence were studied as primary outcome measures.

Results:

Twenty-four prisoners and 24 nonincarcerated controls were included. Prisoners had an average of 2.46 ± 2.38 visits during the study period, compared to 5.04 ± 3.25 for controls (P = 0.001). Follow-up visits occurred more than 30 days after the recommended follow-up time in 57.4% (95% confidence interval [CI]: 44.2%–70.6%) of prisoners, compared to 17.9% (95% CI: 10.2%–25.6%) of controls (P < 0.00001). 70.8% of prisoners (95% CI: 66.3–74.5%) were lost to follow-up, compared to 29.2% of controls (95% CI: 25.5%–32.9%; P < 0.01). Medication nonadherence rates were similar between prisoners (13.6%; 95% CI: 12.1%–15.2%) and controls (12.0%; 95% CI: 11.4%–12.6%; P = 0.78).

Conclusions:

Glaucoma follow-up adherence was significantly worse in prisoners compared to a nonincarcerated control population. Further study into causative factors is needed.

Authors: Ahmed Salwa Abdelkawi , Ghoneim Dina Fouad , Morsy Mona Ebrahim , Hassan Aziza Ahmed , Hassan Mahmoud Abdel Rahman
Published: July 2021

Purpose:

To evaluate the effects of low-level laser therapy (LLLT) on the retina with diabetic retinopathy (DR).

Methods:

Eight Wistar rats were used as a control group, and 64 rats were injected intraperitoneally with 55 mg/kg of streptozotocin to induce diabetes and served as a diabetic group. After the establishment of the DR, the rats were separated into (a) 32 rats with DR; did not receive any treatment, (b) 32 rats with DR were exposed to 670 nm LLLT for 6 successive weeks (2 sessions/week). The retinal protein was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, total antioxidant capacity (TAC), hydrogen peroxide (H2O2), and histological examination.

Results:

LLLT improved retinal proteins such as neurofilament (NF) proteins (200 KDa, 160 KDa, and 86 KDa), neuron-specific enolase (NSE) (46 KDa). Moreover, the percentage changes in TAC were 46.8% (P < 0.001), 14.5% (P < 0.01), 4.8% and 1.6% (P > 0.05), and in H2O2, they were 30% (P < 0.001), 25% (P < 0.001), 20% (P < 0.01), and 5% (P > 0.05) after 1, 2, 4, and 6 weeks, compared with the control. DR displayed swelling and disorganization in the retinal ganglion cells (RGCs) and photoreceptors, congestion of the capillaries in the nerve fiber layer, thickening of the endothelial cells' capillaries, and edema of the outer segment of the photoreceptors layer. The improvement of the retinal structure was achieved after LLLT.

Conclusion:

LLLT could modulate retinal proteins such as NSE and NFs, improve the RGCs, photoreceptors, and reduce the oxidative stress that originated in the retina from diabetes-induced DR.

Published: July 2021

Purpose:

To determine the prevalence of fusional vergence dysfunction (FVD) and its relationship with age, sex, and refractive errors in a population-based study.

Methods:

In this cross-sectional study, all residents of Mashhad, northeast of Iran, aged >1 year were subjected to random stratified cluster sampling. After selecting the participants, they all underwent complete optometric examinations including the measurement of visual acuity and refraction, assessment of binocular vision and accommodative status, and slit-lamp biomicroscopy.

Results:

Of 4453 invited individuals, 3132 participated in the study. After applying the exclusion criteria, statistical analysis was performed on the data of 1683 participants. The prevalence of FVD was 3.2% in all participants, 4.0% in men, and 2.9% in women (P = 0.234). The prevalence of FVD increased linearly with aging from 2.3% in the age group of 10–19 years to 5.4% in the age group of 40–49 years (P = 0.034). The prevalence of myopia, hyperopia, and emmetropia was 11.1%, 29.6%, and 59.3% in participants with FVD and 16.7%, 26.4%, and 57% in participants without FVD, respectively (P = 0.570). Multiple logistic regression analysis only showed a significant association between age and FVD (odds ratio =1.03 95% confidence interval: 1.02–1.05, P = 0.031).

Conclusion:

The prevalence of FVD in this study was higher than most previous reports and increased significantly with aging. FVD had no significant association with sex and refractive errors.

Authors: Gupta Richa , Chauhan Lokesh , Varshney Abhishek
Published: July 2021

Purpose:

To assess digital eye strain (DES) among schoolchildren during lockdown.

Methods:

An online questionnaire-based, cross-sectional study was conducted. A validated, self-administered, electronic questionnaire was circulated among students of 5–18 years of age. The duration of data collection was from May 18, 2020 to May 24, 2020. Rasch-based Computer-Vision Symptom Scale was deployed to measure the DES.

Results:

A total of 654 students (mean age: 12.02 ± 3.9 years) completed the survey. The average per day digital device exposure was 5.2 ± 2.2 h. A total of 507 (92.8%) children reported experiencing at least one asthenopic/dry eye symptom (AS/DS). The most prevalent symptoms were eye redness (69.1%) and heaviness of eyelids (79.7%). Significant positive correlation was reported between age and per day duration of digital device exposure (Pearson correlation 0.25; P < 0.001). Computer vision syndrome (CVS) score for spectacle users was significantly higher (P < 0.001). CVS score was found to correlate significantly with age and duration of digital device exposure (P < 0.001).

Conclusion:

Most of the students surveyed, experienced at least one symptom of DS or AS, indicating a need to educate them about the possible deleterious effects and help them adapt to the currently evolving education system.

Published: July 2021

The aim of this study was to compare the dosimetric parameters of Co-planar Intensity modulated radiotherapy (C-IMRT), non-coplanar (NC-IMRT), and volumetric arc therapy (VMAT) planning technique in hippocampal sparing (HS) whole brain radiotherapy (WBRT). Fifteen patients of brain metastasis (BM) treated with hippocampal sparing whole-brain palliative radiation were selected for this study. C-IMRT, NC-IMRT and VMAT plans were generated for the comparison. Generated plans were evaluated based on planning target volume (PTV) coverage, conformity index (CI), homogeneity index (HI), beam-on time (BOT) and dose delivered to organs at risk (OARs) for the prescribed dose (PD) of 30 Gy in 10 fractions. Statistically significant difference was found in PTVD95%, PTVmax, HI, BOT, MU, Dmax of the brainstem, Dmean of eyes, Dmax of lenses and Dmax, Dmean and D2% of the bilateral hippocampus. However, a non-significant difference was observed in CI, D100% of both the hippocampus, Dmax of the optic chiasm, optic nerves, and Dmax of eyes in all the three planning techniques. Considering the superior plan quality, both NC-IMRT and VMAT are better than the C-IMRT planning technique. Based on beam-on time and delivery efficiency VMAT is found to be superior to both the C-IMRT and NC-IMRT technique. Doses to OARs are very well within the limits in all the three planning techniques.

Authors: Sharma Deepti , Sharma Navneet , Roy Bal G. , Pathak Mallika , Kumar Vinod , Ojha Himanshu
Published: July 2021

Traumatic wounds are the wounds that damage both the skin and the underlying tissues. Bacterial load in wounded tissue triggers elongation of the inflammation phase of wound healing. In case of excessive inflammation, the wound may undergo delayed healing that can lead to complications such as sepsis or amputation. In the present work, a hydrogel using green-synthesized silver nanoparticles (AgNPs) was synthesized and characterized in terms of homogeneity, viscosity, spreadability, excipient compatibility, etc. The hydrogels containing different percentages of AgNPs were tested for healing efficacy in full-thickness excision wound model in adult female Sprague–Dawley (SD) rats. Safety study of hydrogels was performed in SD rats as per the OECD guideline 410. The prepared hydrogels were stable for over 3 months and remain intact on parameters such as homogeneity, pH balance, good spreadability, and extrudability. Healing efficacy study showed that an increased amount of AgNPs in hydrogel enhanced wound contraction over 100% with increased tensile strength and dense aligned collagen fibers in treated wound tissues as compared to standard (silver sulfadiazine), placebo, and sham groups. Dermal toxicity studies showed that there were no signs of irritation, inflammation, and edema on the dorsum of SD rats. Besides, there was no local and systemic toxicity in hydrogel-treated groups.
Study of ambient gamma dose levels at national atmospheric research laboratory, Gadanki, India
Authors: Kumar K Charan , Prasad T. Rajendra , Kamsali Nagaraja
Published: July 2021

Simultaneous observations of ambient gamma dose levels, temperature, relative humidity, and atmospheric pressure were carried out at National Atmospheric Research Laboratory (NARL), Gadanki, India (13.459°N and 79.175°E), from November 2011 to May 2014. The results show that about 92% of ambient gamma dose values lie between 150 and 200 nSv/h and best possible fit resulted in Gaussian fit with adjusted R2 of 0.99. A weak Pearson's correlation coefficient was found between ambient gamma dose levels and selected meteorological parameters measured over the location. No seasonal trend was observed in ambient gamma dose levels, but pronounced seasonal variations in temperature, relative humidity, and air pressure were found. A sudden increase in ambient gamma levels was observed during precipitation event (Nilam cyclone) and may be attributed to an additional contribution of precipitation washed 222Rn progeny aerosols within the atmosphere. The mean ambient gamma dose over NARL was 186 ± 4.3 nSv/h and is within world average given by UNSCEAR.

The State of the Cardiovascular System Under the Action of Industrial Electromagnetic Fields
Authors: Gazya G. V. , Eskov V. V. , Filatov M. A.
Published: July 2021

The influence of industrial low-frequency electromagnetic fields on the human body is currently insufficiently studied. However, such fields are quite common in modern automated production, where various electric drives are used, and they significantly affect the quality of human life. This is especially evident in the conditions of the North, where special ecological factors cause significant changes in the systems of regulation of the body's functions. This study examines the influence of such fields on the parameters of the cardiovascular system of female workers in the oil and gas industry in Russia. Four groups of women were studied, differing in age and electromagnetic field exposure. As a result, the effects of influence of the fields were revealed, especially for the older age group.
The Political Economy of Ivory as a “Conflict Resource”
Authors: White Natasha
Published: July 2021

The past year has seen attention directed, both in policy discourse and the media, towards the implication of Central African non-state armed groups in poaching and ivory trafficking. Engaging with both mainstream political economy analyses and work on the “geographies of resource wars,” this paper turns to the case of ivory as a “conflict resource,” through the case study of the Lord’s Resistance Army. It begins by outlining the contextual specificities and conditions of access, before assessing the compatibility of the resource’s biophysical, spatial and material characteristics with the needs of regional armed groups and the LRA in particular. Though the direction of causality is difficult to untangle, the paper finds that poaching and the trade in ivory by armed groups in Central Africa appears to incur low opportunity costs for relatively high potential gains. Moreover, that ivory qualifies as a “conflict resource” under Le Billon’s (2008) definition in the extent to which it is likely to be implicated in the duration of conflict in the region, both financing and benefitting from a context of insecurity. Future research would benefit from more accessible and robust data; interesting avenues would include an evaluation of the effects of the increasing militarization of poaching strategies - including shoot-to-kill policies - and the potential of igniting grievance-based conflict.
The Components of Dehumanization
Authors: Luna Aniuska
Published: July 2021

Dehumanization is a complex, relational and subjective phenomenon. Studies on it primarily focus on how it enables abuse in the midst of conflict, or how it shapes perceptions of others. Scholars, however, have not deconstructed it into components. The current article breaks down dehumanization into three components: elements, characteristics, and dimensions. It is hoped that the discussion of the connection between the three can encourage additional discussions on how each of the components contributes to dehumanization and how that can help towards undermining it. Until the phenomenon is understood from its most basic to its most elaborate parts, undermining dehumanization as a means to securing positive peace will remain challenging. The components came to the fore through the content analysis of dehumanization in anecdotes from survivors of the Holocaust. The latter study looked into the use of non-human referents applied to humans or their lived experiences. The findings were additionally considered in light of the literature on perpetrators and of samples that matched search criteria but were not deemed dehumanizing.
Looking for Peace in the Australian National Curricula
Authors: Standish Katerina
Published: July 2021

Education can be a source of cultural attitudes—a transmission belt—a cultural institution that can dispense communal values and cultural ideals in both teaching and curriculum. This empirical mixed-methods study utilizes the methodologies of directive (qualitative) and summative (quantitative) content analysis to analyse the national curricular statements of Australia (Early Learning, Foundation to 10 and, Senior 11-12) to determine if three elements common in peace education programs appear: recognition of violence (direct, structural or cultural); addressing conflict nonviolently; and, creating the conditions of positive peace. It finds that despite a copious amount of violent content, overall, the curricula does not recognize such deeds as deliberate acts of harm, that the curricula encompasses limited content regarding transforming conflict nonviolently and that aspects that contribute to positive peace are infrequent and largely lack the intention of creating equanamous space.
Reflections on Peace from Interculturality
Authors: Garcia-Gonzalez Dora
Published: July 2021

This article purpose to think about interculturality in connection with what peace means, since many of the great conflicts in the history of humankind have been provoked by the failure to settle conflicts, by the absence of genuine dialogue and the inability to listen, thus producing violence among persons and among cultures. Therefore, to overcome these situations it is necessary a deep understanding of what peace means, as well as of its relation to justice and ethics. This will make it possible to seek the development of a positive interculturality, within a framework of peace. The existence of interculturality does not necessarily generate violence, even when there are conflicts. Transforming and overcoming these conflicts is the prerequisite for establishing peaceful intercultural relations. The argument in this article is that such transcendence is possible by resorting to the ethical imagination: a creative resource that makes what is absent and desired present and that generates possibilities thought to be inexistent in existing situations. The ethical imagination introduces a constructive view of social change in scenarios in which conflicts are deeply rooted, thereby, facilitating transformation.
Sport and Peace-Building in Divided Societies: A Case Study on Colombia and Northern Ireland
Authors: Cardenas Alexander
Published: July 2021

In recent years, sport has been acknowledged by a broad range of organisations as a viable tool to promote peace in highly volatile contexts. Acknowledging the complexity and myriad of issues that shape and define the Colombian and Northern Irish struggles, this article explores the use of sport to advance peace-building as seen through the lenses of the personnel involved in designing, supporting and implementing sport-based peace interventions (SDP officials) in both regions. This paper found points of commonality and divergence between Colombia and Northern Ireland showing that the unique conflict dynamics in both cases have played a major role in shaping the perceptions of SDP officials with regards to the peace-building dimension of sport, their role as drivers of change and the structure and content of sport for development and peace programs.
Zionism, Imperialism, and Indigeneity in Israel/Palestine: A Critical Analysis
Authors: Ukashi Ran
Published: July 2021

This article explores the similarities and differences between Zionism and archetypical European modes of settler colonialism to demonstrate the incongruence between the two phenomena. This analysis is contextualized around the recent discourse surrounding the competing claims of indigeneity to historic Israel/Palestine. The claims of both the Jewish and Palestinian Arab communities are explored to demonstrate that both communities can rightfully claim degrees of Indigenous connection to the territory, but that Palestinian Arab claims of being the sole Indigenous inheritors of the land are dubious. The analysis utilizes Burton's unmet human needs theory, and Kriesberg's theories on identity and conflict intractability to demonstrate how perpetuating such claims serves to exacerbate inter-group conflict between Israelis and Palestinians. Furthermore, the relationship between Ottoman and British imperialism in the development of both nationalisms is expounded to illustrate the contributory factors of imperial policies to the development of the national aspirations of both social groups.
Capturing the Flag: The Struggle for National Identity in Nonviolent Revolutions
Authors: Hancock Landon , Gurung Anuj
Published: July 2021

One goal of nonviolent resistance movements is to legitimize themselves in opposition to governments by undermining the latter’s leadership. We argue nonviolent groups that can ‘own’ the national identity are more likely to succeed, as they can assert the legitimacy of their vision for the state, and persuade other sectors of society to support their cause. Our argument is supported by the Arab Spring uprisings, where those resistance movements that were able to identify and claim ownership over a homogeneous national identity were more successful in pressing their claims. We view national identity as a component of symbolic power in both successful and unsuccessful nonviolent revolutions. We supplement our argument via a comparison of the Arab Spring uprisings featuring Egypt, Bahrain, and Libya, with nonviolent movements of the past: the ‘early’ cases (Northern Ireland, Iran, and the Philippines) and the color revolutions (Serbia, Georgia, and the Ukraine). We posit that the role of national identity, while not a determinant of success, can play an important role in the struggle for legitimacy, which may help determine the prospects of success for these movements.
Doing Participatory Action Research as a Doctoral Student in the Peace and Conflict Studies Field
Authors: Gittins Phill
Published: July 2021

There is still little written about doing participatory action research (PAR) as a doctoral student. This paper provides a missing first-person account of doing a PAR Ph.D. in the Peace and Conflict Studies (PACS) field. Based on the author’s own experience of using PAR as part of his PACS doctoral degree this paper reflects on why he decided to use PAR in his doctorate project and how he went about doing it. It further highlights some of the benefits (academic and non-academic) of doing a PAR Ph.D., as well as challenges faced and responses to them. Four key lessons learned are also offered with the hope that they will be helpful to others embarking on PAR. The paper also includes a discussion of the broader implications for those interested in doing PAR, as well as a call for more PAR in the PACS field, making the argument that it offers a powerful means for narrowing the oft-cited gap between peace research and peace action.
Getting Graphic: Depictions of Single Stories in Non-Fiction Graphic Novels about Israelis and Palestinians
Authors: Reingold Matt
Published: July 2021

Six recent non-fiction graphic novels about the Palestinian-Israeli conflict are analyzed in order to understand how narratives are constructed and presented about each community. What emerges when considered together is that while complex narratives that challenge hegemonic stereotypes are depicted about the community that the authors favour, their depiction of 'the other' often relies on either stereotypes or omissions and these depictions present single stories of entire communities. I argue how the inclusion of alternative narratives within graphic novels can enhance the text, provide opportunities for readers to gain deeper knowledge about the conflict, and begin to appreciate and recognize the rights of the other can emerge.
Rethinking Peace: Discourse, Memory, Translation, and Dialogue, edited by Alexander Laban Hinton, Giorgio Shani and Jeremiah Alberg. Reviewed by Mohammed Moussa.
Authors: Moussa Mohammed
Published: July 2021

Peace is a protean concept that equally eludes academics and practitioners on the one hand and perpetrators and victims on the other hand. However, this conundrum has not discouraged the preoccupation of peace and conflict studies with fixing the definition of peace once and for all for immediate export to war zones. In this essay, I review the timely book of Rethinking Peace: Discourse, Memory, Translation, and Dialogue which explicitly aims at not only rethinking peace but also providing self-reflexive viable alternatives. My review proceeds according to two steps: first, I identify the key themes of each part and of each chapter; second, I situate the edited volume in a context characterized by two increasingly significant conversations, the interpretivist turn and the decolonizing of knowledge, that at times overlap.

Con motivo de la actualización de la geología regional del Cuadrángulo de Puno (32v) a escala al 50,000, se han desarrollado diversas labores de campo, como ésta contribución que documenta nuevos resultados de rocas mesozoicas del Grupo Yura en las inmediaciones del Distrito de Tiquillaca, (al SO del Lago Titicaca), tales afloramientos solían asignarse a rocas jurásicas del Grupo Lagunillas. El afloramiento en estudio se halla en el Cerro Yana Apacheta, en cuya quebrada principal se elaboró una columna estratigráfica y el perfil correspondiente en el que se encontró el amonite Himalayites treubi DOUVILLE (1912), estableciendo una correlación con las formaciones Chachacumane y Labra. El taxón se describe con base en cinco ejemplares y sus parámetros estándares de tasa de enrollamiento y ornamentación del costillaje. Se considera que el hallazgo de amonites del Tithoniano en el Cuadrángulo 32v amplía y documenta la columna previamente reportada para la localidad y establece una clara correlación con sedimentos del sur de Asia (Indonesia).
 
ABSTRACT
On the occasion of the updating of the regional geology of the Puno Quadrangle (32v) at 50,000 scale, several field works have been developed, such as this contribution that documents new results of Mesozoic rocks of the Yura Group in the vicinity of the Tiquillaca District, (SW of Lake Titicaca), such outcrops used to be assigned to Jurassic rocks of the Lagunillas Group. The outcrop under study is located in Cerro Yana Apacheta, in whose main gorge a stratigraphic column and the corresponding profile was elaborated, in which the ammonite Himalayites treubi DOUVILLE (1912) was found, establishing a correlation with the Chachacumane and Labra formations. The taxon is described based on five specimens and its standard parameters of coiling rate and rib ornamentation. The finding of Tithonian ammonites in Quadrangle 32v is considered to extend and document the column previously reported for the locality and establishes a clear correlation with sediments from South Asia (Indonesia).
Covid-19 period and competences in higher education- study on cooperation and assertivity
Authors: Galinha Sónia Alexandre , São-João Ricardo
Published: July 2021

Within this pandemic associated with Covid-19, psychological health occupies a prominent place as a result of a situation of forced isolation. Impacts can lead to an increase in mental health disorders as well as a set of adaptive reactions inherent to the recovery.  Cooperation is conceived as the ability to jointly operationalize knowledge, attitudes and skills with a view to achieving a common purpose; and assertiveness is conceived as a bilateral behaviour that emphasizes the importance of considering the desires, thoughts and feelings of both the sender and the recipient of the assertive message, predictive of academic success. In this line, the main objective of this study is to present the results of the application of the Global Cooperation Assessment Scale (EAGC) and the findings levels of the Global Assertiveness Assessment Scale (EAGA). The study used a non-probabilistic sample for convenience of 101 Portuguese higher education students. EAGC and EAGA are a self-registration closed-ended Likert type 5 points, closed-response scales that allows assessing the degree of competence in respondents' cooperation and assertiveness. Both scales were administered online in spring semester 2019/2020, with the link to the questionnaire being made available to students the computer platform ensuring the response of a single survey per respondent whose participation in the study was voluntary. The treatment of the information, as well as its statistical analysis, was supported by the R software (R Core Team, 2020), having been assured the confidentiality and anonymity of the respondents. Sociodemographic variables were also used, which seemed promising in contextualizing, interpreting, and discussing the results. The value of the sample mean obtained at EAGC=35 (± 6.5), thus revealing a high capacity for cooperation and in the EAGA=31 (± 5.53), thus revealing a high assertive competence who attend higher education.

The conversion of mangrove forest to aquaculture activity leads to the destruction of habitat diversity and ecosystem. Shrimp farming is a sector of aquaculture that has a high potential for poverty alleviation and rural development in Tumpat, Kelantan. However, the development of this activity induces changes that potentially have negative impacts on the environment, one of which is vegetation deterioration. Pulau Terendak, Tumpat has been through the phase of conversion area which established as a shrimp farming area at year 1989. Using remote sensing technique, this study was implemented to identify the current status and total ranges of shrimp farming area by comparing vegetation losses from year 1989 to 2017. Land use and land cover maps of study area was analyzed through a process called image classification. Supervised classification using Maximum Likelihood algorithm was utilized to assess vegetation losses of the 45 hectare of shrimp farm area. Four main land use classes were detected namely water, bare area, dense vegetation and small vegetation. Result showed that in 25 years, vegetation of the area had decline to 23.3% while bare soil or open area increased to 8.5%. Digital analyzed data was compared to field verification procedure, accuracy assessment in this study was recorded at 64.3%. There are many causes for vegetation or mangrove loss but in this case the conversion of mangroves to shrimp farms has caused considerable attention whereby vegetation losses was found at serious state. Output of this study could suggest the authorities to plan a good strategy to address this issue in cost effective with maximum benefits for the environment and society.

Authors: Mensah Francis , Agyapong Kingsley , Acheampong Augustine
Published: July 2021

Purpose: The study sought to categorise students based on the preferences that influence their choice of distance education in Ghana. 

Methodology: Questionnaires were used to collect data from 120 students taking part in the UEW distance education programme at the Kumasi Girls SHS Study Center. Respondents were segmented into three clusters (highly, moderately, and least satisfied) based on four preferences (price, quality, packaging, and social boding) that influenced their satisfaction with the distance education programme.

Result: Findings from both hierarchical and non-hierarchical cluster analysis with squared Euclidean distance and Ward’s method showed that the highly satisfied cluster was driven by quality of service and the fees (i.e. price) of the UEW distance education programme. A further analysis of the differences between the clusters indicated that satisfaction with the UEW distance programme significantly differs across the three segments.

Unique Contribution to theory and practice: UEW must take advantage of the significant impact of service quality and price factors on customer satisfaction that runs through all the segments to develop and implement strategic decisions in order to achieve a competitive advantage in the distance education market

Objectives: The study explores the main health care workers (HCWs) clinical characteristics and related behaviors with procedures that impose risk of acquiring COVID.19 infection.

Method: This was a cross-sectional study conducted at East Jeddah Hospital. 100 Health Care worker participants who were detected as COVID-19 cases from March to July 2020 was obtained from the infection control department, and these HCWs were asked to fill out a questionnaire designed for this study. Data was analyzed using SPSS, and categorical data presented as counts and proportions.

Results: Among the100 HCWs who contracted COVID-19, there was a marked predominance of females (69.0%) over males (31.0%). When dealing with COVID-19 cases, 93.1% of HCWs reported wearing a surgical mask and 61% an N95 mask, while only 69–80% reported wearing gloves, a disposable gown and eye protection. The procedures found to increase the risk of infection were taking nasopharyngeal swabs (23.0%), inserting nasogastric tubes (22.0%), ventilation (17.0%), and tracheal intubation (14.0%).

Conclusion: This study confirms that noncompliance with the use of PPE as well as performing a specific procedure and working in close contact (<1.5 meters) for longer than 20 minutes increased the risk of infection. No minimal protective measures against SARS-CoV-2 infection.

Recommendation: Analysis of the data obtained in this study demonstrates the significant of using personal protective equipment's effectively among health care workers and its vital role in reducing rate of infection transmission. However, further cohort study required in the same field to obtain a comprehensive outcomes.
