Objective: There is still no consensus on the time period of wearing protective collar after Anterior Cervical Discectomy and Fusion (ACDF). We aim to investigate the optimal time period of wearing collar after ACDF. Methods: We retrospectively reviewed patients with cervical spondylosis who underwent one or two segment ACDF during January 2016 and December 2017, and included 97 patients who met inclusion and exclusion criteria. Patients were divided into three groups, 1-4 week group, 5-8 week group and 9-12 week group, according to the actual time period of wearing collar after ACDF. We analyzed Japanese Orthopedic Association (JOA) score, Axial Symptom (AS) score and Neck Disability Index (NDI) before surgery and at post-operative 3 months to investigate the optimal time period of wearing collar after ACDF procedure. Results: 1) JOA score: All three groups have a better post-operative JOA score compared with that before surgery (paired t test, p<0.05). There is no significant difference among the three groups with respect to post-operative JOA (ANOVA, p>0.05). 2) AS score: The post-operative AS scores of 1-4 week group and 5-8 week group were significantly better than that before surgery (paired t test, p>0.05). While the post-operative AS score of 9-12 week group was significantly worse than preoperative AS score (paired t test, p<0.05). 3) NDI: All three groups have a better post-operative NDI compared with that before surgery (McNemar test, p<0.05). Of note, in 5-8 weeks group, the percentage of no deficit increased by 45%, and the percentage of mild deficit decreased by 45% accordingly. That percentage is 26% and 31% in 1-4 week group and 9-12 week group, respectively. There was significant difference among these three groups (Fisher’s exact probability test, p<0.05). Conclusion: For cervical spondylosis patients who underwent 1 or 2 segment ACDF, the optimal time period of wearing protective is 5-8 weeks. This time period results in comparable neurological outcome, least risk of axial symptoms, and highest chance of no deficit with neck function.

Tuberculosis (TB) is an essential problem for healthcare systems especially in developing countries. TB continues to pose a significant global health burden [1]. Bacillus Calmette-Guérin (BCG) is an important vaccine used to prevent Tuberculosis (TB), especially meningeal TB and disseminated TB disease in children [2]. BCG is prepared from live bovine tuberculosis bacillus, and is given to protect against TB. Although vaccination against TB by means of BCG is widespread all over the world and is generally considered to be safe, but serious adverse reactions can occur. These may be minor such as abscess formation or skin ulceration at the site of vaccination to major adverse reaction such as fatal disseminated infection especially in patients with immune deficiency [3]. These adverse reactions after BCG vaccination depend on the BCG dose, vaccine strain, vaccine administration method, injection technique, and recipient’s underlying immune status [4]. The aim of this case report is to point out that clinical suspicion of BCG-induced osteomyelitis is warranted in pediatric patients with chronic symptoms of pain, limping, swelling and a limited ROM in the extremity. We also aimed to remind that imaging and culture studies may guide the clinician although tissue biopsies and genetic tests can confirm the histopathology and to review related articles.

Background: Essential Tremor (ET) is the most common movement disorder, yet the location of the primary disease substrate continues to be a matter of debate. In this study, we aimed to evaluate ocular movement abnormalities with Electrooculography (EOG) in patients with ET to find a possible location of disease pathology. Methods: Electrooculographic evaluation including saccade, tracking, optokinetic, gaze and positional tests were performed to 36 ET patients and 36 healthy subjects. Patient age on the onset of the tremor, duration of the disease, characteristics and the location of the tremor were also investigated. Fahn- Tolosa-Marin tremor rating scale was used to determine the tremor severity. Differences of abnormal test results between patient and control groups were analysed with Pearson’s and Fisher’s Exact and correlation analyses of EOG tests and clinical data were performed with Spearman’s and Pearson’s correlation tests. Results: There was not any significant difference in EOG tests between the ET patients and controls. Significant correlation was only found between EOG abnormality and patient age in correlation analyses. Conclusions: Our results showed that ET patients may not have specific EOG test abnormalities. These tests would be used especially in the different diagnosis of other movement disorders.

Objective: Genuvarum deformity experience knee instability. This deformity can lead the patient to sever osteoarthritis. The recovery of postural stability is very important to prevention of these patients. Strategies aimed at stabilizing the muscle can have a long-term effect on the joint. This study was performed to determine the relationship between muscle stabilization strategies and knee instability, in order to determine how people with knee Genuvarum, respond to rapid absorption and muscle co- contraction during landing task. Methods: Twenty female participants, (10 normal and 10 Genuvarum) in the present study. The subjects were land by preferred lower limb from a table (30 cm high) on a force plate. Vertical ground reaction force, time to peak of vertical reaction force, velocity of vertical ground reaction force to reach the maximum, time to stability in X and Y directions and resultant vector were calculated as postural control parameters. Also surface electromyography of transverse abdominal/int. oblique, vastus medialis, vastus lateralis, lateral gastrocnemius, and medial gastrocnemius muscles were recorded during landing. Motor control strategy were measured by similarity index and voluntary response index. Results: There are significant difference between Genuvarum and Healthy subjects in motor control strategy (P<0.05).A significant difference are detected in postural control parameters between two groups (P<0.05). Conclusion: Genuvarum deformity may be linked to altered quadriceps, abdominal and gastrocnemius muscles reciprocal co-activation patterns during landing task. In addition, may be affected voluntary motor control strategy in synergy concepts. Postural control is affected in these deformity and shock absorption may be reduced in parallel to increase of response vector and reduce of instability in landing task.

Method: The research participants were recruited via disseminating an electronic survey on Facebook Messenger. We used the sample of 812 participants from our previous study that focused on resilience toward C19P. Result: Most coping styles correlated statistically significantly with the level of C19P at different domains including psychological, psychosomatic, economic, and social factors. At least two nations out of the five had statistically different scores for all 14 coping styles (p <0.05). The coping styles including selfdistraction, use of emotional support, use of instrumental support, behavioral disengagement, humor, religion, and self-blame were statistically significantly affected by age (p <0.05).
Long-term dynamics for stocks of sablefish Anoplopoma fimbria in the western Bering Sea and prospects for their fishery
Authors: Zolotov A. O.
Published: July 2021

Sablefish is an endemic species of the North Pacific. Its range extends from California Peninsula, along the Pacific coast of the US and Canada to Aleutian Islands and further, along the Pacific coast of Kamchatka and the Kuriles to the central part of Honshu Island. They dwell also in the Bering Sea and southeastern Okhotsk Sea. Sablefish are the most abundant in the southeastern Bering Sea and in the Gulf of Alaska, that is conditioned by favorable conditions for their larvae and juveniles. In the Asian part of the range, the environments are generally more severe, and reproduction of sablefish is rather risky. Following to the results of modern genetic studies, the sablefish stocks are distinguished by high genetic homogeneity that suggests a common population with the main spawning grounds in the southeastern Bering Sea, at the Pacific coasts of Aleutian Islands, in the Gulf of Alaska, and at the coasts of British Columbia, Washington, Oregon and California. Dynamics of the sablefish biomass is considered on the data of bottom and midwater trawl surveys conducted by TINRO in 2003–2020, fishery statistics, and accessible data of NOAA (USA). Sharp increasing of the biomass and annual catches is noted both in the eastern and western Bering Sea in the last few years because of appearance of several strong year-classes. Western Bering Sea stock depends on migration of recruits from the common spawning grounds in the southeastern Bering Sea. For the western Bering Sea, two main ways of such migration are possible: i) active migration of juveniles with benthic habitat; and ii) passive transfer of pelagic larvae and early juveniles across the Bering Sea through the system of surface currents. The latter mechanism supports the sablefish recruitment in the bays of the western Bering Sea and, to a lesser extent, at the eastern coast of Kamchatka. Sablefish in the West Bering Sea fishery zone were caught in 2010–2020 mostly as by-catch for trawling and longline fishery (93 %), other 7 % were landed by specialized longline fishery. The basic points for managing the sablefish fishery in the West Bering Sea zone are defined. About 400 t of sablefish is permissible to catch annually in the West Bering Sea fishery zone in conditions of modern high stock of this species. This value includes 100–120 t that will inevitably be caught as by-catch and the rest of 280–300 t is a foreseeable resource for organization of specialized fishery.

HIGHER EDUCATION IN ONLINE ENVIRONMENT – CHALLENGES AND POSSIBLE SOLUTIONS
Authors: Drăghicescu Luminiţa Mihaela , Stăncescu Ioana
Published: July 2021

In the current national and international context, the education “hosted” in the online environment, which was once only a secondary solution, rarely used, has become the main way to ensure the continuity of the learning process. In this study, we aimed to capture the reactions of those who were the first to experiment an exclusively online, learning process, i.e. the reactions of the students. We used an investigative approach focused on the following objectives: identifying the perception of students/learners regarding the efficiency and quality of the educational process carried out in the online environment and highlighting ways to improve teaching activities conducted online. The main research method was the questionnaire-based survey. The questionnaire was administered online, integrating a series of items that addressed issues such as: students’ participation in educational activities, problems encountered, solutions to optimize the didactic process conducted in the online environment. Following the investigative approach, the main conclusions are the following: most of the surveyed students consider that the educational activities carried out in the online environment do not have the same efficiency as the direct activities (face to face); the main problems highlighted by the respondents were: overload, fatigue, demotivation, learning difficulties in understanding and operating with certain content, poor Internet connection, but also the lack of necessary indications to facilitate learning. We appreciate that the results of our study may be relevant for practitioners in the field of education, especially for those from higher education, but also for all those interested in digital education.

It is suggested that jujube might benefit exercise-induced immune fluctuations, specifically on neutrophils’ apoptosis regulation, but its cellular mechanism is unclear. This study aimed to investigate the effect of one-week supplemen- tation with Ziziphus jujuba on pro- and anti-apoptotic protein levels of neutrophils in response to a session of circuit resistance exercise. Fourteen young, healthy male students completed a session of circuit resistance exercise (75% 1RM, nine exercises, three sets) in two groups (n=7). While one group received a placebo, the other group was supplemented with jujube (0.5 g/kg body weight suspended in 2.5 cc distilled water) started a weekday before the exercise session. Blood samples were collected 30 minutes before, immediately, and two hours after the exercise. Neutrophils were col- lected and pro- (Calpain-1, Bax, Caspase-3) and anti-apoptotic (Calpastatin, XIAP) proteins measured with ELISA. In- tracellular calcium ([Ca 2+ ]i) was assessed using the Atomic Absorption/ Flame Emission method. Repeated-Measures ANOVA was used for the interaction effects of TIME×GROUP (3×2) at the significance level (p) of 0.05. The SPSS software was used for analyses. Levels of ([Ca 2+ ]i), expression of calpain-, and caspase-3 were increased in response to circuit resistance exercise (p<0.05). In contrast, supplementation with jujube suppressed these changes (p<0.01). The data indicate that a single session of intensive circuit resistance exercise elevated apoptosis signalling in human neutrophils with the involvement of [Ca 2+ ]i-Calpastatin-Calpain axis upstream caspase-3. Supplementation with the jujube solution attenuated cell death signalling, possibly by providing energy for neutrophils. Otherwise, the improvement of the anti- oxidant status might be protective against ROS-induced apoptosis during exercise.

Published: July 2021

A segurança à navegação é um fator primordial para garantir aos navios acesso aos portos. Obras de dragagens são necessárias para a manutenção dos canais de navegação diante do processo de assoreamento em regiões estuarinas. Entretanto, o volume, em metros cúbicos dragados, na região portuária do Complexo Estuarino de Paranaguá (CEP), aumentou ao longo do tempo. O presente estudo se restringe aos setores que interessam à navegação e às instalações portuárias, isto é, o eixo E-W do CEP, que abrange os trechos do canal de acesso aos portos paranaenses nas baías de Paranaguá e Antonina. O total de sedimentos realocados entre 1999 e 2018 nos trechos do canal foi da ordem de 42.517.662,79 m³. A manutenção destes setores é extremamente onerosa, uma vez que mais de 4.000.000 m³.a-1 de material sedimentar são retirados atualmente para garantir acessibilidade aos navios. Ao estimar a produção de sedimentos na área de drenagem do CEP, obteve-se o valor anual de 197.017,23 ton. Dessa forma, torna-se necessário desenvolver estratégias para a retenção de sedimentos nas áreas fonte, a fim de garantir a prosperidade das atividades portuárias nos próximos anos. Recomendações à expansão dos portos na região foram apresentadas ao final.  Silting in the Bays of Antonina and Paranaguá - PR: Integrated Analysis of Sedimentation Sources and Dragging WorksA B S T R A C TSafety in navigation is a primordial aspect to the ports. Dredging works are necessary for the maintenance of the navigation channels before the process of silting in estuarine regions. However, the volume in cubic meters dredged in the port region of the Paranaguá Estuary Complex (CEP) has increased over time. This study is restricted to sectors that are of interest to navigation and to port installation, in other words, the E-W axis of the CEP that includes the sections of the access channel to the ports of Paraná in the bays of Paranaguá and Antonina. The total of relocated sediments between 1999 and 2018 in the canal segments is of the order of 42.517.662,79 m³. The maintenance of these sectors becomes extremely costly, since more than 4.000.000 m³.a-1 of sedimentary material is removed to guarantee accessibility to the ships. When estimating the sediment production in the CEP drainage area, the annual value of 197,017.23 tons is obtained. Thus, it becomes necessary to develop strategies for retaining sediments in the source areas, in order to guarantee the prosperity of port activities in the coming years. Recommendations for expanding ports in the region were presented at the end.Keywords: Hydrographic Units. Sedimentary Dynamics. Sedimentary Disposal. Port Environmental Management.

O entendimento dos efeitos climáticos e do uso do solo em conjunto é crucial para análise ambiental e prevenções de desastres naturais. O objetivo deste trabalho é analisar a vulnerabilidade à erosão hídrica do solo na bacia hidrográfica do rio Araguaia. Usou-se dados de precipitação (Agência Nacional das Águas); uso e ocupação da terra (Projeto MapBiomas); declividade (Instituto Nacional de Pesquisas Espaciais) e de solo (Empresa Brasileira de Pesquisas Agropecuária) no cálculo de mapas através do geoprocessamento para obter-se a representação da erosão hídrica do solo. A bacia hidrográfica do rio Araguaia caracteriza-se na maior parte por zonas de transição de estabilidade e vulnerabilidade, porém destaca-se as áreas estáveis nas proximidades da foz, regiões críticas á sudoeste (Rio das Mortes), nos limites (leste) do Alto Araguaia, nas partes sudeste e sudoeste do Baixo Araguaia. Na escala climática, a precipitação não apresenta riscos significativos. No entanto, o intenso uso e ocupação da terra na região foi a forçante que maior agravou a vulnerabilidade, principalmente em áreas (declives e solo) naturalmente instáveis. Assim, algumas cidades precisam estar em alerta para possíveis eventos erosivos.     Vulnerability to soil water erosion, Araguaia basin riverA B S T R A C TThe Understanding climate effects and land use together is crucial for environmental analysis and natural disaster prevention. The objective of this work is to analyze the vulnerability to soil water erosion in the hydrographic basin of the Araguaia river. Rainfall data (National Water Agency) was used; land use and occupation (MapBiomas Project); slope (National Institute for Space Research) and soil (Brazilian Agricultural Research Corporation) in the calculation of maps through geoprocessing to obtain the representation of soil water erosion. The hydrographic basin of the Araguaia river is characterized in the most part by transition zones of stability and vulnerability, however the stable areas in the vicinity of the mouth stand out, critical regions to the southwest (Rio das Mortes), on the (eastern) limits of the Alto Araguaia, in the southeast and southwest parts of the Lower Araguaia. On the climate scale, the rainfall does not present significant risks. However, the intense use and occupation of land in the region was the forcing that increased the risk, mainly in naturally unstable areas (slopes and soil). Thus, some cities need to be alert to possible erosive events.

Published: July 2021

Water is one of the most important requirements in daily life, which represents the largest part of the Earth. As a result of the economic, industrial and social development in most countries led to increased pollution in water resources. It is, therefore, necessary to monitor water quality continuously to prevent a future catastrophe that adversely affects the quality and quantity of water wealth. Geographic Information System (GIS) is used in various fields to monitor, analyze data collected from different geographical locations. Integration of GIS and other technologies has become an indispensable tool. This gives us direct control over solution expansion, cost reduction, powerful complex case analysis as well as increased accuracy and efficiency of geospatial data. In recent years, many combinations of GIS with different technologies such as remote sensing, wireless sensor networks, internet of things approaches have been proposed due to the rapid progress of technology development in many applications. However, in last several years, there is no survey paper has been published about water quality using the integration of GIS and other technologies. Therefore, this paper investigates the status of continuous search in the field of GIS and its integration with other technologies (Remote Sensing, Internet of Things, Web, etc.) for water quality management and monitoring to maintain the water resources in a proper way. As conclusions, the integration of the GIS with these technologies is a powerful platform for analyzing and processing big data and mapping geographic remotely in less time, less cost, high speed and with more accurate details and in real time compared to traditional geographic information systems. This paper also highlights future research trends about the cooperation of GIS with other technologies for matters that are related to water quality. Doi: 10.28991/HIJ-2021-02-03-10 Full Text: PDF

As the twentieth anniversary of 9/11 approaches, we contemplate and reflect on the current social/political imagination of terror(ism) and U.S./Canadian patriotism. For educators seeking to unpack 9/11 and its reverberations, it is important to highlight Islamophobic and anti-Muslim racism, discrimination, prejudice, and violence, as well as to consider Muslim students’ lived experiences. (Re)thinking about whose voices are included (or not) within the nexus of sociopolitical power is an important step toward justice and then rapprochement within and beyond the classroom. We consider this assemblage of articles to be a distinctly communal effort that responds to and attempts to disrupt the (perpetual) echoes of terror(ism) which became amplified by/through the events of 9/11.

Published: July 2021

AbstrakPenelitian ini bertujuan untuk menjelaskan transmisi memori peristiwa 65 dari generasi pertama ke post-generasi dalam karya sastra. Metode penelitian yang digunakan, yakni deskriptif kualitatif. Penelitian ini merupakan kajian postmemory Marianne Hirch. Sumber data penelitian adalah novel Pulang karya Leila S. Chudori dan Amba karya Laksmi Pamuntjak. Data penelitiannya adalah frasa, kalimat, atau paragraf yang merepresentasikan gambaran generasi pertama dan post-generasi, proses transmisi memori, dan rekonstruksi memori. Teknik analisis data menggunakan teknik interaktif, yaitu dengan cara reduksi data, sajian data, dan penarikan kesimpulan. Hasil dari penelitian ini menunjukkan bahwa (1) terdapat tiga generasi dalam proses transmisi memori, yaitu generasi pertama sebagai tokoh yang mengalami peristiwa 65 secara langsung, generasi 1.5 dan kedua sebagai penerima transmisi memori; (2) familial postmemory dilakukan melalui garis keturunan keluarga dan afiliative postmemory melalui buku, museum, foto, surat pribadi, dokumen sejarah, dan narasi yang berkembang di masyarakat; (3) konstruksi memori oleh tokoh post-generasi yang diwujudkan dengan penerimaan maupun penolakan. Penerimaan memunculkan rasa trauma, was-was, atau perubahan identitas yang mirip dengan generasi pertama. Sementara itu, sikap penolakan menempatkan cerita sebagai mitos yang sudah kedaluwarsa. Kata kunci: post-memori, generasi pertama, post-generasi, peristiwa 65 AbstractThis study aims to explain the memory transmission of events from the first generation to the post-generation in literary works. The research method used is descriptive qualitative. This research is a postmemory study of Marianne Hirch. The source of the research data is the novel Pulang by Leila S. Schudori and Amba by Laksmi Pamuntjak. The research data are phrases, sentences, or paragraphs that represent first-generation and post-generation descriptions, memory transmission processes, and memory reconstruction. The data analysis technique used interactive techniques, namely by way of data reduction, data presentation, and drawing conclusions. The results of this study are (1) there are three generations in the memory transmission process, namely the first generation as a character who experiences events directly, the 1.5 generation and the second as a memory transmission receiver; (2) familial postmemory is carried out through family lineages and affiliative postmemory through books, museums, photos, personal letters, historical documents, and narratives that develop in society; (3) memory construction by postgeneration figures which is realized by acceptance or rejection. Acceptance creates a sense of trauma, anxiety, or a change of identity similar to that of the first generation. Meanwhile, the attitude of rejection places the story as an outdated myth. Keywords: postmemory, first generation, post-generation, event 65
