Authors: Sankar K , Krishnan V Gokula , Kumar S Sendil , Pushpa P , Laxmi B Prathusha
Published: October 2023

The brain, which has billions of cells, is the largest and most complex organ in the human body. A brain tumor is the primary malignant intracranial tumor of the central nervous system that develops most frequently. They are frequently found too late for effective therapy. The use of minimally invasive procedures is necessary to make a diagnosis and monitor a tumor of the central nervous system's response to therapy. There exist three distinct classifications of tumors, namely benign, premalignant, and malignant. This study concentrated on using deep learning to identify brain tumors (BT) using normal or abnormal brain pictures. Numerous methodologies have been employed to augment the quality of images, encompassing image smoothing and noise restoration procedures. The present study employs the proposed Adaptive Weighted Frost filter as it has been identified as the optimal approach for noise reduction in BT photographs. The Swin Transformer technology is employed for the purpose of classifying the BT. The efficiency of the Tree Growth Optimization (TGA) model for Swin transformer hyper parameter tweaking has been evaluated in this work. Before using our unique BT dataset for extensive experimental comparisons, medical specialists carefully examined it down to the pixel level. The predicted model achieved the greatest F1 score of 99.82% and the maximum accuracy, recall, and 100%, respectively.

The Relation of E. Cassirer's Theory of Myth to the «Phenomenology of Spirit» by Hegel
Authors:   Saratov State University, Isaeva A.V.
Published: October 2023

The article analyses the relation of E. Cassirer’s theory of myth to the «Phenomenology of Spirit» by Hegel. The original basis for the theory of mythic thought by E. Cassirer and his philosophy of symbolic forms is Hegel’s philosophy. Carrying out the historicophilosophical investigation, it’s impossible not to notice a direct connection between Cassirer’s analysis of symbolic forms and Hegel’s phenomenology of spirit – the detailed structure and architectonics of the «Philosophy of Symbolic Forms» reproduces Hegel’s dialectic to the smallest detail. Nevertheless, considerable difference of E.Cassirer’s phenomenology is the application of transcendental method to analyse the individual phenomena of consciousness.

Losartan Has a Comparable Effect to Human Recombinant ACE2 in Reducing Interleukin-6 (IL-6) Levels on Human Adipocytes Exposed to SARS-CoV-2 Spike Protein
Authors: Hermawan Hanestya Oky , Ardiana Meity , Suryawan I Gde Rurus , Harsoyo Primasitha Maharany , Rafli Muhammad
Published: October 2023

BACKGROUND: High angiotensin-converting enzyme 2 (ACE2) expression in adipocyte cells facilitates the initiation of SARS-CoV-2 infection and triggers a cytokine storm. This finding suggests that obesity is an independent risk factor for the severity of the symptoms caused by COVID-19. The use of cardiovascular medications that focus on ACE2, such as angiotensin II receptor blockers, remains controversial, and their effects on inflammatory cytokine production and ACE2 expression in cells, especially adipocytes, remain inconsistent.METHODS: The human adipocytes were isolated from obese donor subcutaneous adipose tissue and infected with the subunit S1 spike protein from SARS-Cov-2. The adipocytes were later treated with either hrsACE2 or losartan. The levels of ACE2 and inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α were measured using enzyme linked immunosorbent assay (ELISA). ACE2 and S1 spike protein binding assays were also performed. RESULTS: ACE2, IL-6, and TNF-α levels were significantly increased in human adipocyte cells infected with SARS-Cov-2 but not IL-1β. There was a statistically significant positive correlation between ACE2 and IL-6 (r=0.878, p<0.001). Administration of losartan and hrsACE2 was shown to reduce ACE2 levels and its binding to the SARS-CoV-2 S1 spike protein, and IL-6 levels were statistically significant, but had no significant effect on IL-1β or TNF-α levels.CONCLUSION: This study shows that the administration of losartan in COVID-19 may not be harmful, but instead has a protective effect similar to that of hrsACE2 in preventing a cytokine storm, especially IL-6.KEYWORDS: obesity, SARS-CoV-2, losartan, IL-6, ACE2

Long COVID: A Chronic Shortage of Blood. Pathophysiology and Treatment Proposal
Authors: Molenaar Pieter A.
Published: October 2023

My hypothesis is that the signs and symptoms of Long COVID can be explained by a shortage of blood in the body and a resulting deficient blood flow through nearly all organs. This shortage arises through damage to the blood-producing organs during the acute phase, while the breakdown of blood continues as normal, after an initial increase. In order to ensure the perfusion of organs that are directly necessary for survival, the body takes the emergency measure of diverting blood from other organs and tissues. The perfusion of the blood-producing organs is also affected by this distribution measure, which hinders the smooth recovery of the total blood volume. The body is stuck in this vicious circle: a shortage of circulating blood hinders the recovery of blood production. This explains the long duration of Long COVID. My proposed treatment of Long COVID focuses on the recovery of the correct volume of blood in the body of the right composition by the very careful administration of donor blood products under continuous expert supervision. A trial treatment can be performed in any hospital without much additional preparations, and has a lower associated risk for the patient than analysing the total blood. A diagnosis ex juvantibus, by therapeutic response, is therefore preferable, and will result in the healing process starting earlier. Indications in blood laboratory values of a shortage of blood are a high serum ferritin due to internal breakdown of blood and values for haematocrit and albumin at reciprocal extremes of the reference ranges due to a stagnation of blood production.

Published: October 2023

Measles remains a highly contagious and potentially severe infectious disease, necessitating high vaccine coverage. However, misinformation and measles vaccine hesitancy/resistance posed significant challenges to achieving this goal. The COVID-19 pandemic further exacerbated these challenges, leading to a measles outbreak in Jordan in 2023. This study aimed to investigate the acceptance of the Measles-Rubella (MR) vaccine among parents in Jordan and identify its associated determinants. This cross-sectional questionnaire-based study was conducted using a previously Arabic-validated version of the Parental Attitudes towards Childhood Vaccines (PACV) survey instrument. Data collection took place in October 2023, and the final study sample comprised a total of 391 parents, with mothers representing 69.8% of the participants (n = 273). The majority of participating parents expressed either resistance (n = 169, 43.2%) or hesitancy (n = 168, 43.0%) towards MR vaccination, while only 54 participants (13.8%) expressed MR vaccine acceptance. Multivariate analysis revealed that trust in vaccine safety/efficacy, behavior, and having fewer offspring were significantly associated with MR vaccine acceptance. The current study revealed a concerning level of MR vaccine hesitancy/resistance among parents in Jordan. Urgent and targeted interventions are strongly recommended to address this issue, including mass campaigns aimed at building trust in the MR vaccine safety/efficacy. Additionally, there is an urgent need for effective public health initiatives to ensure sufficient measles vaccine coverage to prevent future outbreaks of this serious disease.

Published: October 2023

Outcome of redo-mitral valve replacement in the small mitral annulus with the use of the chimney technology is not well documented. From 2019 to 2020, 77 consecutive patients underwent redo-mitral valve replacement with the use of the chimney technology because of a small mitral annulus. To evaluate heart structural integrity and clinical outcomes, postoperative clinical data and echocardiograms were examined. Mean age was 56.7 ± 15.98 years. All patients underwent mitral valve surgery of which 62 were mitral valve replacements, 7 mitral valve repairs, and 8 double valve replacements. Preoperative Mitral valve mean gradient was 18.07 ± 9.40 mmHg. Postoperative mitral prosthesis size 28.51 ± 1.22 mm. The median increment of mitral size enlargement was 4 (0, 6) valve sizes. Mean mitral gradient coming out of the operating room was 10.34 ± 2.12 mmHg and at follow-up echocardiogram performed at 3 years after the procedure was 10.36 ± 1.70 mmHg. One-year survival was 93.3%, while 4-year survival was 89.3% with no reoperation. Use of the chimney technology in small mitral valve re-mitral valve replacement results in larger valve sizes. Moreover, the mean gradients over the mitral valve are acceptable intraoperatively and over time.

Tourism carrying capacity remains pivotal for ensuring sustainable development within protected terrains, accentuating the balance between conservation, socio-economic benefits, and visitor satisfaction. This study delves into the intricate dimensions of this balance, focusing on the Katon-Karagay National Park (KKNP). Merging comprehensive empirical data accrued from fieldwork within the park, calculations surrounding recreational loads, and a synthesis of relevant literature, the study designed a methodology. This included calculated techniques incorporating ecological and tourist social capacities, the psychocomfort approach, and an ongoing monitoring approach, supplemented by exclusive data from the park's administration. Key findings underscored the significance of an adaptive balance, revealing specific permissible recreational loads for different park zones. For instance, zones of quiet recreation evidenced up to 5 people/ha, while active recreation zones fluctuated between 20 to 100 people/ha. Monitoring evidenced critical environmental changes, shaping recommendations for effective tourism flow regulation, ensuring alignment with established norms and ecological preservation. The exploration substantiates the indispensability of a meticulously structured approach to ascertain tourism carrying capacity, emphasizing the harmony achievable between environmental sanctity and human pursuits. KKNP's empirical data serves as a paradigm, guiding sustainable tourism frameworks for similar ecologically sensitive regions.

Published: October 2023

The main purpose of this study is to determine how pre-school teacher candidates' epistemological beliefs affect their views and conceptualizations about teaching philosophy with children. The secondary aim is to determine the epistemological belief levels of preschool teacher candidates. In order to achieve these goals, a mixed method, which combines qualitative and quantitative research methods, was used. The research was carried out with 52 participants studying in the field of pre-school education at a foundation university affiliated to YÖK in Istanbul. First, the Epistemological Belief Scale for Learning was applied to the participants in order to reach quantitative data, and the results were analyzed through descriptive statistics. Three subgroups of three persons (lower, middle and upper epistemological profiles) were formed within the framework of the epistemological belief scores reached. Opinion form for learning philosophy with children was applied to the sub-samples. In order to analyze the qualitative data obtained, an inductive content analysis was carried out through the continuous comparison method. Within the scope of the analysis results, it is seen that the average of epistemological belief scores of preschool teacher candidates is higher than the general average of the scale. At the same time, it is seen that pre-school teacher candidates with high epistemological beliefs emphasize the vision of science literacy within the scope of teaching philosophy with children, thinking skills, sense of curiosity, and child-centered approaches.The results were discussed within the framework of the relevant literature and suggestions were made in this context.

Çocuk Haklarının Kısa Felsefi Tarihinde ‘Çocuklar için Felsefe’
Authors: YOLSAL MURTEZA Eylem
Published: October 2023

Bu çalışmada genel olarak çocuk haklarının felsefi ve tarihi gelişimine odaklanılacaktır. Düşünce tarihinde çocuk hakları son bir yüz yıldır meşru bir inceleme konusu olmuştur. Bu görece yeni ilginin nedenlerini insan ve çocuk hakları bildirgelerinin ilan edilmesinde bulabiliriz. Ancak bundan bile önce Fransız Devrimindeki kadın hakları hareketlerine ve 1989 Çocuk Haklarına Dair Sözleşme’sine doğrudan etkileri söz konusu olan Jean-Jacques Rousseau’nun düşünceleri mevcuttur. Çocukluk safhalarını ve çocuk eğitimini klasik argüman dışında inceleyen Rousseau aynı zamanda 19.yy daki bir çeşit çocuk kurtuluş hareketine de yön vermiştir. Bildirgeler ve felsefi düşüncede ön plana çıkmaya başlayan çocuk ve hakları konularının özellikle günümüzde demokrasilerdeki önemini ise Çocuklar için Felsefe’nin John Dewey’e götürülen kökeninde inceleyeceğiz. Dewey’in demokrasiyi bir yaşam tarzı olarak görmesinden yola çıkarak hem çocuk haklarının bu kısa tarihinde haklarla edinilen kazanımların tekrar kaybedilmemesi hem de yeni hakların gelişmesi ve gündeme gelebilmesi amacıyla demokratik yurttaşlığın öneminden bahsedilecektir. Demokrasi, yurttaşlık ve çocuk haklarının kavranılması konularının ise Çocuklar için Felsefe metoduyla etkili bir biçimde gerçekleşeceğini ve yurttaşlar arasılığı güçlendireceğini öne süreceğiz.

Published: October 2023

Permeability variation in the vertical direction, a typical sandstone reservoir heterogeneity, can trap a large amount of oil in the low-permeability layer. We performed water-alternating-gas (WAG) injection and CO2 foam flooding on a specially constructed millimeter-sized layered sandstone and investigated fluid distribution using high-resolution X-ray microtomography. Based on the segmented images, CO2 capillary-trapping capacity, oil recovery, Euler number, shaper factor, capillary pressure, and fluid flow conductivity were calculated. Our results show that increasing the number of WAG cycles favored CO2 capillary trapping, and oil recovery was enhanced by the WAG strategy. However, there was still a significant amount of oil trapped in the low-permeability layer. After the WAG injection, the connectivity of the residual oil clusters decreased, the capillary pressure of the oil clusters increased, and oil flow conductivity decreased. This was not conducive to further oil recovery. The subsequent injection of CO2 foam effectively recovered the oil in the low-permeability layer. During the no-injection period, we observed a crossflow phenomenon caused by gravity segregation (the high-permeability layer was located below the low-permeability layer), i.e., oil in the low-permeability layer decreased while oil in the high-permeability layer increased, which is beneficial for subsequent oil production. Furthermore, CO2 moved upward driven by gravity, and although capillary barriers could prevent CO2 from escaping, subsequent water injection was essential to improve the stability of CO2 capillary trapping. This work accurately quantifies the distribution of oil and gas in high- and low-permeability layers, thus providing fundamental data for oil recovery and CO2 trapping in reservoirs with vertical heterogeneity. Although the sample used in the experiment was not natural reservoir rock, our results imply that when the permeability ratio between the two layers is greater than 2, sufficient attention must be paid to the fluid distribution differences caused by this layered heterogeneity. Different displacement strategies, such as WAG and CO2 foam flooding, or gravity differences between oil and gas can be used to enhance oil recovery.
Lymphatic drainage of sinonasal malignancies and the role of sentinel node biopsies
Authors: Kashani Fatemeh , Weiss Bernhard G , Bartenstein Peter , Canis Martin , Haubner Frank
Published: October 2023

Background: Locoregional recurrence is a critical factor in the prognosis of sinonasal malignancies. Due to the rarity of these tumours, as well as the heterogeneity of histologies and anatomical subsites, there is little evidence regarding the rate and location of regional metastases in sinonasal malignancies. Elective regional lymph node dissection in the therapy of sinonasal malignancies has become controversial. On the one hand, elective regional lymph node dissection is considered to be an overtreatment in the cN0 cases. On the other hand, undetected occult lymphatic metastases are associated with a poor prognosis. In this study, we discuss the role of lymph node scintigraphy as a minimally invasive procedure in the treatment of sinonasal malignancies based on our two years of practical experience and the currently available data.
Results: This is a descriptive, monocentric, retrospective study, including 20 cases of cN0 malignant sinonasal neoplasm, that underwent a surgical therapy between 2020 and 2022. The following aspects were investigated: tumour entity, localisation of the primary tumour, tumoral stage, localisation of the sentinel lymph nodes, and postoperative complications. Squamous cell carcinoma was the most frequently diagnosed tumour entity (50%), followed by adenocarcinoma (20%) and malignant melanoma (15%), adenoid cystic carcinoma and mucoepidermoid carcinoma. Sentinel lymph nodes were most frequently found in the ipsilateral neck region I (45%), followed by the ipsilateral neck region II (40%). In all cases, the removed lymph nodes were free of malignancy. There were no postoperative complications due to lymph node biopsy. There were no recurrences during the study period.
Conclusion: Sentinel node biopsy adds more safety to the management of cN0 sinonasal malignancies due to its low morbidity. Elective neck dissection can be avoided in these cases.
Chloroprocaine 3% for anesthesia during cesarean section in a patient with dopa-responsive dystonia: a case report
Authors: zhou wenqin , Luo Dong
Published: October 2023

Background
Dopa-responsive dystonia (DRD) is a rare autosomal dominant hereditary disorder with a prevalence of 0.5 per million population. The disease is characterized by onset of dystonia in childhood, progressive aggravation of the dystonia with diurnal fluctuation, and complete or near complete alleviation of symptoms with low-dose oral levodopa. The incidence of DRD is low, and only a few publications have described this disorder connected with anesthesia.
Case presentation
We present a case involving a pregnant woman with DRD who continued levodopa/benserazide throughout the pregnancy. The perioperative anesthesia management was described. We used chloroprocaine 3% for epidural anesthesia during cesarean section.
Conclusion
In summary, levodopa/benserazide was continued throughout our patient’s pregnancy with a good obstetric outcome, and chloroprocaine was safely used in epidural anesthesia without deterioration of her dystonic symptoms.
Pioneering Discoveries in Wireless Power Generation across Wide Geographical Ranges Harnessing Medium-Wave Radio Broadcasting Infrastructure
Authors: Shoji Eiichi
Published: October 2023

This study conducted field experiments using the radio-wave energy harvester of hoop-shaped radio (HOOPRA) to elucidate the relationship between the distance from the medium-wave (MW) radio broadcasting station and the resonance voltage as an index of harvested energy. Accordingly, we derived a numerical equation that described the relationship between the distance and voltage with a strong correlation coefficient of R2 > 0.996. HOOPRA can illuminate ultrabright white, green, and red LEDs within a 5 km radius of the public NHK JOFG (927 kHz, 5 kW) in Fukui, thereby serving as a valuable energy source for the 150,000 residents (60,000 households) in this region. The public JOAK (594 kHz, 300 kW) and JOAB (693 kHz, 500 kW) were examined for similar field experiments in the Kanto region. The results revealed that HOOPRA could illuminate ultrabright white, green, and red LEDs within a radius of 30 km and ultrabright red LEDs within a radius of 50 km from JOAB, which will benefit the 23 million residents (1.1 million households) in this region.
Implementing a PROM tool to improve the supportive care services referral patterns of adult idiopathic pulmonary fibrosis patients in a pulmonary clinic: A quality improvement pilot project
Authors: FOWORA TEMITOPE
Published: October 2023

Background: Delayed referrals to supportive care services often result in impaired health-related quality of life (HRQL) among patients with idiopathic pulmonary fibrosis (IPF). Pulmonologists can adhere to the ATS clinical treatment guidelines through the use of the patient-reported outcome measure (PROM) tool, which can improve referral to supportive care services.
Local problem: No PROM tool in the pulmonary clinic could assess patients' health-related quality of life (HRQL) of patients due to the disease burden of Idiopathic pulmonary fibrosis (IPF), hence delayed referral to supportive care services.
Method:  A pre and post-retrospective analysis of the chart
Intervention: The King's Brief Interstitial Lung Disease (KBILD) questionnaire was implemented as an evidenced-based PROM tool in the pulmonary clinic
Result: The use of the K-BILD questionnaire increased pulmonologist's awareness of stability or progression of disease burden among IPF patients based on HRQL, hence an increase in the referral of patients to supportive care services
Conclusion: The results suggest that implementing an evidence-based PROM tool such as the KBILD questionnaire can increase referrals to supportive care services in a busy pulmonary clinic
Technology everywhere! But who’s got the time? The influence of time pressures on technology integration in Australian secondary mathematics
Authors: Zunica Ben
Published: October 2023

Over the past 30 years, teachers have been urged to increase their use of digital technology in the classroom. However, mathematics teachers have been slow to integrate ICT, even though mathematics is naturally aligned with technology. While researchers have documented a variety of time and other related factors that contribute to this resistance, there has been little in-depth analysis of teacher reasoning that inhibits technology integration in mathematics. This article presents four case studies of secondary mathematics teachers employed in Australian schools that investigates the adverse effects of time pressures in not only inhibiting a teacher’s desire to use technology but removing as an option altogether. Data was collected in the form of interviews, lesson planning documentation and notes from observation lessons. Thematic analysis was used to determine how time pressures inhibited participants ability to use technology in their pedagogy. Three time-related obstacles were identified. The first was a lack of time to prepare lessons, the second was content-laden syllabuses and finally, the need to prepare students for traditional assessments. Participants claimed that these obstacles often proved too great to overcome, causing them to abandon any use of technology. I argue that when the obstacles to technology integration are perceived as too difficult to overcome, it is not enough to provide poorly targeted professional learning or encouragement to work harder to integrate technology. Rather, existing time pressures must be alleviated in terms of workload and syllabus demands if we want to remove the inhibitors to technology integration in mathematics.

Background
The role of metals and trace elements in the progression of cancer can be both passive and active. While some metals have clearly emerged as carcinogens, the homeostasis of other trace elements only trails cancer evolution and therefore offers some potential prognostic values. At this stage, modern-standard datasets including a large number of elements are missing. The present analysis established a first metallomic spectrum by relating the blood concentration of metals and trace elements in patients with sarcoma with survival data.
Methods
Patients with sarcoma and controls were retrospectively selected from the International Sarcoma Kindred Study database. Blood samples were prospectively collected at the Leon Bérard Cancer Center from February 2012 to July 2019. Stable specimens and copper isotopes (65Cu/63Cu) were analyzed using Triple Quadrupole ICP-MS and the MC-ICP-MS Nu Plasma HR 500. Wilcoxon rank sum test, log-rank test, and multivariate Cox regression models were used for statistics.
Results
In total, 151 patients and 59 healthy controls were included. At the time of blood sample collection, 62% of patients had locally advanced or metastatic disease, and 49% were undergoing chemotherapy. The median overall survival (OS) was 16.6 months. Copper (Cu), copper/zinc (Cu/Zn) and potassium /rubidium (K/Rb) ratio were significantly higher in patients compared to controls, whereas δ65Cu, selenium (Se), sulfur (S), Rb, K, phosphorus (P), iron (Fe) and Se / S ratio were significantly lower. Cu, Cu / Zn and K / Rb were also significantly higher in advanced compared to early stage disease. Of note, whereas S and Se were significantly correlated in patients, no correlation was observed in controls. Importantly, levels of K, Rb, Se, Fe, P, Si, S, δ65Cu, Cu, S / Se and Cu/Zn ratio were independently associated with OS.
Conclusions
These results depict the metallomic spectrum in sarcoma and highlight substantial variation associated with survival, some of them paving the way for future anti-cancer therapy development

Ultimate scaling limit in ferroelectric switching has been attracting broad attention in the fields of materials science and nanoelectronics1,2. Despite the immense efforts to scale down ferroelectric features, however, only few materials have been shown to exhibit ferroelectricity at the unit cell level3,4. Here, we report a controllable unit cell-scale domain in the brownmillerite oxides consisting of alternating octahedral/tetrahedral unit cells. By combining atomic-scale imaging and in-situ transmission electron microscopy, we directly probed unit cell-wide ferroelectricity patterned by neutral unit cell-wide walls and its switchable characteristics. The first-principles phonon calculations confirm that the phonon modes related with oxygen-octahedra are fully decoupled from those with oxygen-tetrahedra in the brownmillerite oxides, and such localized oxygen-tetrahedral phonons stabilize the unit cell-wide domain. Unit cell-wide ferroelectricity in our study provides unprecedented scaling limit of ferroelectric thin films for designing high-density memory devices at the quantum limit.

Published: October 2023

Objectives: To investigate the effectiveness of AcceleDent Aura vibrating device on rate of canine retraction.
Materials and Methods: Thirty-two patients requiring extraction of upper first premolars and canine retraction were randomly allocated with a 1:1 ratio into either no-appliance group or the AcceleDent Aura appliance group. Canine retraction was done applying 150gm of retraction force using NiTi coil springs on 16*22 stainless steel archwires. The duration of the study was 4 months. Digital models were obtained directly after extraction of upper first premolars and at monthly intervals during canine retraction for recording the monthly as well as the total distance moved by the canine. Digitized models were superimposed on the initial model and data were statistically analyzed. Anchorage loss, rotation, tipping, torque and root condition were evaluated using cone beam computed tomography imaging. Pain was evaluated by visual analog scale.
Results: No patients were dropped-out during this study. There was no statistically significant difference between both groups regarding the total distance travelled by the canine (P=0.436), as well as the rate of canine retraction per month (P=0.17). Regarding the pain level, there was no statistically significant difference between the two groups at day 0 (P=0.721), after 24 hrs.(P=0.882), after 72 hrs. (P=0.378) and after 7 days(P=0.964).
Conclusion: AcceleDent Aura was not able to accelerate orthodontic tooth movement. Pain level couldn’t be reduced by vibrational force with an AcceleDent device during orthodontic treatment. Root condition was not affected by the vibrational forces.
A step towards sustainability: Life cycle assessment of coffee produced in the indigenous community of Ocotepec, Chiapas, Mexico

Published: October 2023

Coffee is one of the tropical crops of great relevance. Mexico occupies one of the first places to produce it. Chiapas is the state that contributes the most significant amount of grain to the national and international market, harvested by organized groups such as cooperatives of origin indigenous. In these regions, cultivation is divided into five stages: cultivation, harvest, wet processing, dry processing and roasting. Thus, the agroecological approach based on the agroforestry system of coffee in the community of Ocotepec allowed generating an intercultural dialogue with a Zoque indigenous cooperative, where its members expressed the need to develop information regarding their production process and thus take the relevant decisions. Concerning environmental impacts. The life cycle analysis was applied as a methodological tool to evaluate the process of producing a kilogram of ground coffee in its honey and speciality varieties offered to the national market, showing the most significant impacts for both types of coffee. Cultivation level (water consumption around 80% and land use with effects close to 98%), wet processing (impacting the ecotoxicity of water sources close to 99% followed by marine ecotoxicity with 73%) and in its distribution stage affecting at least 15 environmental categories, likewise, comparative tests were carried out to calculate the carbon footprint and the water footprint, with shade-grown honey coffee being the type of coffee that has the most negligible environmental impact and contributes the most profits to the cooperative.
