Published: October 2023

Based on the 2020 Community Service Program (KKN) team analysis, Pakembinangun Village has been planning tourism village development. Pakembinangun Village has yet to be visited by tourists visiting Kaliurang, even though it has natural resources suitable for tourism. The village also has complete health facilities and has long been known as a place of healing. Based on this analysis, healing tourism was chosen as the focus program. Healing tourism utilizes the potential of natural, artificial, and human resources to treat and improve physical, mental, spiritual, and social health. At present, truly holistic healing tourism has yet to be founded in Indonesia. This healing tourism development program aims to increase economic growth, improve people's welfare, increase business opportunities for the community, increase community involvement, build financial independence, and utilize natural and cultural resources. To achieve this goal, several methods used were observation, interviews, literature study, Focus Group Discussion, socialization, and student involvement through KKN. A growth center strategy model was used to realize this idea. The initial development strategy centered on one location (growth center) will spread growth to secondary and tertiary areas (production centers). Integrating governance for developing growth and production centers will produce a multiplier effect regarding quality, quantity, and sustainability. In addition, this strategic model will also encourage the emergence of superior product innovations in growth and production centers. The community involvement model is used to develop the services in Wijayakusuma Healing Park. The existence of these services opens up community business opportunities. It increases village incomes through visitor fees, healthy drinks, and food production by Farmer's Women Group or Kelompok Wanita Tani, tour guides, administrative officers, health checkers, gymnastics instructors, masseurs, accommodation provision, dance, etc.

The application of appropriate technology on the concatenate of silkworm (Tubifex tubifex) and catfish (Clarias sp.) aquaculture was carried out in Salak Malang and Salam Hamlets, Banjarharjo Village, Kalibawang District, Kulon Progo Regency, Special Region of Yogyakarta, Indonesia. The main concept of this appropriate technology is to establish a mutualism symbiosis by creating water recirculation between silkworms and catfish ponds. The results show that an increase in the water flow frequency from catfish ponds to silkworm culture areas has the potential to provide higher silkworm production. The integration of silkworm and catfish aquaculture may also reduce catfish's Feed Conversion Ratio (FCR) to around 0.7-0.9. This alleviation in FCR value indicates the feed efficiency that reduces feed costs, making catfish farming more effective and efficient. By applying this appropriate technology, the number of silkworms required for catfish seed in Banjarharjo Village would still be fulfilled, and simultaneously the availability of fish-based protein from catfish available for the silkworm farmer and the local community.

Wonosobo Regency is dominated by slopes where 80% of the land is careened for more than 20 degrees. In this condition, it is challenging to find a workforce for farming activity, resulting in a high cost for any agricultural activities—one of the activities that need much labor is the weeding activity. The introduction of appropriate technology is required to support agriculture’s sustainability which will efficiently reduce the production cost. This paper proposed an empowerment activity model for farmers in the slope area, which targeted two main goals: introducing the multifunction weeding tools to increase the rice weeding activity’s efficiency and increasing the farmer group competency in the operational management of the agricultural machinery. The empowerment activity was incorporated with a farmer group called Tani Sejahtera in Rojoimo village, Wonosobo. This group has become a model for other farmer groups owning several agricultural machineries and a workshop to develop appropriate technology in their farming. The empowerment was done through (1) the accompaniment in the appropriate weeding tool’s development from design to evaluation and (2) training for the farming group on the agricultural machinery’s operational management. These empowerment activities affected the farmer group’s independency accretion towards the appropriate technology development that is needed for the farming activities where the cost can be reduced, along with the farmer group's comprehension of agricultural machinery operational management is increased. This empowerment activity can be a model to escalate farmers’ independence in sloping land regarding the development and operational management of the appropriate agricultural tools and machinery.

One important oil center is in the Samigaluh sub-district, Kulon Progo, Yogyakarta, as there are several small business groups, and most produce clove oil. Gerbosari village, one of the villages in the Samigaluh sub-district, is one of Indonesia's largest clove oil producers. Yet, the development is not significant enough as distillation technology is still considered minimal and less profitable. The problem revolving around clove oil production for small businesses is that the produced oil's quality is deficient. A notable amount of iron (Fe) can still be found in the oil, resulting in a relatively low selling price. Community service was suggested based on applying appropriate technology targeting the clove oil refining actors or industry on the Medium, Small, and Micro Enterprises (MSME) scale in Gerbosari, namely MSME Surya Wulan, to obtain export quality clove oil eligible to Standar Nasional Indonesia (SNI) or National Standards of Indonesia. This year's community empowerment activities proceeded the previous year when the zeolite adsorbent was made, which was done at CV Fruitanol Energy and has undergone physicochemical characterization in FMIPA UGM's chemistry laboratory. Zeolite adsorbents were applied for the clove oil's purification process and then tested for quality to determine compliance with SNI standards and carry out chemical and physical properties characterization. This year's community empowerment focused on installing and applying clove oil purification technology using an energy-efficient distillation. Clove oil production's business feasibility study from this technology application was also carried out to describe the market's production potential, demand, and continuity. The results were summarized in an integrated module to transfer knowledge to MSME Surya Wulan. Furthermore, coaching will be carried out to MSME Surya Wulan to produce clove oils independently and sustainably.

The era of globalization can lead to changes in the lifestyle of more modern society. As a result, people tend to have a new culture that they deem more practical than local culture. One of the factors that cause the local culture to tend to be forgotten at this time is the need for future generations to be interested in learning and inheriting their own culture. It’s also a fact that Indonesian people prefer foreign culture to local culture because it is considered more practical and in accordance with the times. Many local cultures have faded because of the lack of future generations interested in studying. This research is applied in the context of efforts to preserve the local culture of the macapat song. The method used in this research is a direct practice through traditional performing arts activities of the macapat song; relevant literature studies also support it. The results show that the macapat song has various philosophical values ​​that can be used as references in life. These values ​​can be internalized in the attitudes and behavior of the nation's next generation. The values ​​in the macapat song are relevant to education for sustainable development.

As the COVID-19 pandemic emerged, hand soap demand is increasing compared to previous times. People are expected to wash their hands at offices, shopping centers, hospitals, and other public areas to prevent COVID-19 virus transmission. As the demand grows, there are more opportunities for people in local communities to produce hand soaps contributing to the high-quality hand soap needs fulfillment. The production method is effective, economically beneficial, and does not irritate the skin. Thus, hand soap production training (both online and offline), branding, and marketing were provided to achieve this objective. Several parties participated in the online activity, such as the Department of Chemistry's Chemical Physics Laboratory Employees, the Maxi Consulting Team, and the Head of HIPPI DIY--the event was also published in Majalah Kagama. The offline training was conducted in Ganjuran, Sleman, and Kasihan Bantul, as the midwives and women's groups participated. The branding and marketing training program had also been conducted four times (once online and thrice offline), along with monitoring activities to track marketing progress.
Keynote Talk: Education for Sustainable Development - Enabling Higher Education and Enhancing Community Engagement
Authors: Tabucanon Mario T.
Published: October 2023

The global calls to action on Sustainable Development (SD) have been triggered by the existential threat to human existence caused by unsustainable human actions. The critical issue is to have a clear understanding on what SD and Education for Sustainable Development (ESD) are about, and on the transformative societal actions they entail in the interface of the development and knowledge sectors. The role of higher education is to bring closer together science and SD. There have been positive trends to the effect that SD is being integrated into education, and vice versa, and ESD cuts across formal, non-formal and informal education sectors; but major works remain in accelerating and upscaling sustainable actions, as well as in having policy coherence on ESD across sectors and subsectors aligned with the roadmap to sustainability in higher education. The launching of the UN Agenda 2030 and the Sustainable Development Goals (SDGs) has shifted the focus of the ESD approach to one that enables and supports the implementation of the SDGs. Unfortunately, according to the UN ESCAP 2022 Report on SDG Progress, as of now, none of the SDGs are on track for 2030. None of the SDGs hit the 2021 timeline, and the full achievements of the targets based on current trajectories are getting delayed, especially on Climate Action (SDG 13) which is regressing. For effective SDG implementation, Quality Education (SDG 4; SDG 4.7 on ESD) and Partnership (SDG 17) are both enablers and integrators to be embedded in all implementation programs across the board. To be effective, SDG implementation needs to be rooted in community and local stakeholders’ engagements. SDGs must be localized, underpinned by local values, culture and heritage, focusing on holistic, whole-community approach, and transdisciplinary problem solving. The UNESCO ‘ESD for 2030’ Roadmap provides guidance through five priority action areas - Advancing Policy; Transforming learning environments; Building capacity of educators and trainers; Empowering and mobilizing youth; and Accelerating sustainable solutions at local level (community engagement). Two flagship initiatives of the United Nations University Institute for the Advanced Study of Sustainability (UNU-IAS) illustrate important roles of higher education in SD and community engagement - one is a network of higher education institutions known as the Promotion of Sustainability in Postgraduate Education and Research Network (ProSPER.Net); and the other is a regional/local network of organizations, the Regional Centres of Expertise on ESD (RCEs).
Keynote Talk: Community Empowerment Through Student Community Service
Authors: Prijambada Irfan Dwidya
Published: October 2023

Although the trend of poverty rate continues to go downwards, Indonesia is still facing a problem of poverty that cannot be ignored. The Central Statistics Agency (BPS) noted that the number of poor Indonesians is more in rural than in urban areas. Community empowerment program is the priority program of the government to alleviate poverty. In the community empowerment, the process of improvement in the quality of life of the population occurs with the community participation. In contrast to the development paradigm, the empowerment paradigm positions community not as an object but as a subject. In order to prepare students as members of society who are able to face present and future challenges, Universitas Gadjah Mada equips their students with various abilities to think critically and creatively, to communicate and to be able to solve problems. To develop these abilities, students need to participate in complex, meaningful projects that require sustained engagement, collaboration, research, management of resources, and the development of an ambitious performance or product. A community empowerment project is a form of project intended as a complex, and meaningful project. Involving students in community empowerment projects is a characteristic of Universitas Gadjah Mada (UGM) since its establishment. Student involvement in community empowerment projects is packaged in the form of Community Service Learning, which is named as Kuliah Kerja Nyata (KKN) in Bahasa Indonesia. KKN has a paradigm that places the community as the subject/actor while students participating in the KKN function as agents of change with the role of motivators, innovators, and facilitators for the community they accompanied. Such procedures should encourage joint learning between students and the community.

Purpose: to present our experience of surgical treatment of peripheral retinoschisis without macular involvement using a scleral buckle.Material and methods. 31 patients (31 eyes) with peripheral retinoschisis (PR) without macular involvement, including 19 cases complicated by retinal detachment, underwent scleral buckling with cryoretinopexy of rupture zones and vitreoretinal degeneration and transscleral drainage of subretinal fluid.Results. In 12 (39 %) cases, the retina reattached within 24 hours after the operation, in 11 (35 %) cases, it reattached within 1 week, while in 8 (26 %) cases complete resorption of the subretinal fluid and retinal reattachment occurred 1 to 6 months after the operation. By the end of the 6-month follow-up period, retinal reattachment was achieved in all cases.Conclusion. The surgical treatment tactics of PR without macular involvement by scleral buckling is effective and pathogenetically validated, especially in the case of progressing lretinoschisis.
The impact of technique of conjunctive wound suturing during sinus trabeculectomy on the formation of the filter bleb and the hypotensive efficiency of the operation
Authors: Gar’kavenko V. V. , Balashova P. M.
Published: October 2023

Purpose. To study how filtration blebs change in the postoperative period after applying the innovative patented suture during sinus trabeculectomy (STE).Material and methods. 105 patients (105 eyes) with primary open-angle glaucoma were randomized into 2 gender and age matched groups. In group 1, the conjunctival wound was sutured with separate continuous sutures on the conjunctiva and the Tenon's capsule. In group 2, the wound was sealed according to an innovative method. Before surgery, patients underwent a comprehensive examination, including visometry, tonometry, perimetry, and retinal tomography. In the postoperative period (1 day, 1, 2 weeks, 1, 3, 6 and 12 months after the STE), the changes of filtration blebs characteristics were assessed using the Würzburg bleb classification score (WBCS).Results. In group 2, one day after the surgery, IOP showed a decrease 0.8 mm Hg greater than in group 1. One month after surgery, the decrease was 1.5 mm Hg greater. The difference in IOP levels between the study groups persisted for up to 1 year (with a significant difference of 3.6 mm Hg after 3 months, and 3.8 mm Hg after 1 year, p = 0.001). The development of intraoperative and early postoperative complications was generally comparable. In group 1, an additional suture sealing was required in 11 8 % of cases due to external filtration. In group 2, no additional sutures were required (p = 0.01). The two groups revealed differences in the degree of vascularization of the conjunctiva and in the presence of conjunctival microcysts, as well as in the degree of encapsulation (p < 0.001) Group 2 treated by the innovative suturing technique showed better results.Conclusion. The innovative method of applying a sealing suture after STE quickens the normalization of the main characteristics of filtration blebs in comparison with the control group within 1 year after the intervention.

Published: October 2023

Inflammatory complications of cataract phacoemulsification are among the most urgent and potentially vision-threatening conditions. Corneal melting is a rare but clinically significant condition preceding corneal perforation. The main risk factors are the use of nonsteroidal anti-inflammatory drugs (NSAIDs), severe dry eye disease and rheumatic diseases. The paper presents a literature review and offers an analysis of a clinical case of corneal melting after cataract phacoemulsification in a female patient with severe dry eye disease, which was undiagnosed before surgery. The follow-up period was 5 years. The possibilities and limitations of multiple methods of corneal melting treatment at the stages of persistent epithelial defect and corneal ulcer are discussed. The mechanism of disease development and its link with the pathogenesis of dry eye disease and the role of topical NSAIDs as a trigger for the initiation and progression of corneal melting are considered.

Authors: Denisova E. V. , Geras’kina E. A. , Katargina L. A.
Published: October 2023

Familial exudative vitreoretinopathy (FEVR) is a hereditary disease characterized by abnormal angiogenesis and avascular zones (AZ) on the retinal periphery. The leading method of treatment of its early stages (1–3) is laser coagulation (LC) of AZ and pathological retinal vessels.Purpose. To study the efficiency of retinal laser coagulation in children with various stages of FEVR.Material and methods. 65 children with FEVR (82 eyes) were observed after retinal LC for 6 months to 10 years (on average, 3 years). The efficiency of laser treatment was evaluated after 2–3 months. We regarded the result as stabilization if no progression of the disease could be observed over the entire follow-up period (at least 12 months), either with or without an additional LC.Results. The efficiency of a single LC in children with FEVR in stage 1 was 100 %, in stage 2, 50 to 56 %, in stage 3, 10 to 50 %, in stage 4, 20 to 33 %. The proportion of cases with long-term (over 12 months) stabilization after additional LC sessions was diminishing according to the initial severity of clinical manifestations: from 75–100 % in stages 1–2 to 41–60 % in stage 3 and to 17–20 % in stage 4.Conclusion. LC efficiency of AZ and pathological retinal vessels in children with FEVR is inversely proportional to the stage of the disease. In more than half of the cases, repeated sessions of LC are required to achieve stabilization. The persistence of vascular activity after LC or the appearance of new vascular malformations are prognostic signs of further FEVR progression. The results obtained indicate the need for an early detection of the disease and an LC procedure to prevent the development of extensive retinal detachment, as well as regular dynamic observation of the patients and further study of the pathogenetic mechanisms of FEVR progression.

Published: October 2023

Purpose: to evaluate the effectiveness of transscleral micropulse cyclophotocoagulation (mCPC) in patients with end-stage glaucoma.Material and methods. 38 patients aged 76.6 ± 7.1 years with end-stage refractory glaucoma were examined, revealing subjective complaints, uncompensated IOP at the maximum hypotensive mode, prior multiple surgical interventions. Indications for mCPC to be performed on a SUPRA 810 device (Quantel Medical, France) according to a modified protocol, in which the laser energy flux is 121.8 J/cm2, were determined. In order to prevent postoperative inflammation after mCPC, a combined drug Floas-T® (glucocorticosteroid fluorometholone + tobramycin) was used.Results. A week after mCPC, the hypotensive effect was achieved in all 38 cases. IOP showed a 30.8 % decrease from the baseline. Considering an additional mCPC given to 14 patients, the entire group showed an IOP 22.8 % decrease (from 34.7 to 26.8 ± 2.9 mm Hg, p < 0.05) achieved after an 18 months’ follow-up. The combined drug Floas-T® was found to contribute to a subjective and clinical improvement, revealing no signs of an increased IOP.Conclusion. The use of mCPC in the treatment of patients with repeatedly operated refractory end-stage glaucoma who receive a maximum hypotensive mode should be estimated as a positive measure. The combined drug based on fluoroquinolone and tobramycin has demonstrated high effectiveness of anti-inflammatory prevention. A survey showed a subjective improvement in the patients’ quality of life. The mCPC method can be recommended as one of the components of a comprehensive rehabilitation program for patients with end-stage glaucoma.

Published: October 2023

Purpose: to analyze morphometric, clinical and functional manifestations of glaucomatous optical neuropathy in congenital childhood glaucoma (CG).Material and methods. We examined 103 children (163 eyes) with (CG), including 54 children (86 eyes) with primary congenital glaucoma (PCG) aged 1 month to 17 years. In addition to the regular ophthalmological examination, we performed optical coherence tomography of the optic nerve head (ONH), flash visual evoked potentials, total and rhythmic electroretinogram, oscillatory potentials (OP), echobiometry of the eye axial length.Results. The thickness of the retinal nerve fiber layer peripapillary (pRNFL) ranged from 32 to 120 μm, averaging 71.67 ± 18.2 μm. The thinning was detected in 83.0% of cases, primarily in the temporal sectors (90.6%). As the condition progressed, a tendency to progressive thinning of the RNFL was detected. The minimum rim width (BMO-MRW) ranged from 87 to 336 μm and was reduced in most children (14 out of 16, 87.5%). A strong inverse correlation of the neuroretinal rim with the depth (r = -0.69) and the width (r = -0.93) of the excavation was detected. Also, a strong direct correlation was established between the minimum neuroretinal rim width reduction and the thickness of the BMO-MRW and pRNFL (r = 0.79), as well as the upper and lower temporal sectors (r = 0.81 and r = 0.88, respectively). The thickness of the ganglion cell (GC) layer varied from 8 to 23 μm and averaged 14.64 ± 4.89 μm, with a reduction recorded in most cases (64.7%). All patients showed a decrease in oscillatory potentials (OP) by 40% or more (6.31 ± 2.33) as compared to the control group (20.24 ± 6.28). Thinning of the RNFL was registered in these eyes in 90.6% of cases averagely (p < 0.05) and in the upper and the lower temporal sectors (p < 0.05).Conclusion. RNFL thickness, the minimal width of the BMO-MRW and the OP are the most sensitive criteria to assess the degree of glaucomatous optic neuropathy in children with PСG. The study of the GC layer thickness can serve as an additional diagnostic criterion of assessing the state of the ONH.

Published: October 2023

Purpose: to study the prevalence of various chronic infections, the frequency of their reactivation and characteristic associations of microorganisms in patients with optic neuritis of various etiologies.Material and methods. 13 patients with optic neuritis (ON) and 12 patients with ON and multiple sclerosis were tested for a broad range of infectious agents in their blood serum.Results. All patients were shown to have mixed infections; 64 % of them had an association of 4 or more infectious agents. The patients of both groups were infected with Epstein-Barr virus (100 %), Cytomegalovirus (92 %) and Herpex simplex viruses (92 %) types 1 and/or 2 with serological signs of their reactivation. The combination of Herpes virus reactivation, Toxoplasma and urogenital infection was more often detected in patients with demyelinating ON. In patients with multiple sclerosis, a mutual correlation was detected: the higher the degree of infection (combination of 5 or more pathogens), the lower the visual acuity at the onset of the disease (p < 0.05) and the less favourable the vision prognosis.Conclusion. Possibly, mixed infection may play an important role in the pathogenesis of ON, including that of demyelinating etiology, as a trigger or an aggravating factor.

Astarlı örgü veya fleece kumaş olarak da adlandırılan iki iplik ve üç iplik yuvarlak örme kumaşlar, iyi termal konforları, düşük hava geçirgenlikleri ve soğuğa karşı korumaları sayesinde son zamanlarda spor ve outdoor giysiler için aranılan kumaşların başında gelmektedir. Çalışma ile iki iplik örme kumaşlarda zemin iplik besleme miktarı sabit tutulup astar iplik kasnak dereceleri değiştirilmek suretiyle elde edilen farklı astar ipliği oranlarının kumaş fiziksel özellikleri, patlama mukavemeti ve boyutsal özellikler üzerine etkilerinin ortaya koyulması amaçlanmıştır. Elde edilen bulgular SPSS 21 paket programı kullanılarak istatistiksel olarak değerlendirilmiştir. Çalışma sonuçları zemin iplik besleme miktarı sabit tutulduğu için ilmek yoğunluğu ile ifade edilen kumaş sıklığının değişmediğini, astar iplik oranının artmasıyla kumaş gramaj ve kalınlığının artarken patlama mukavemetinin kısmen düştüğünü, may dönmesi ve boyutsal değişim oranlarının etkilenmediğini göstermiştir.

Bu çalışmanın hedefi, lif çekimi sırasında polimere titanyum (Ti) nanopartikül katkılama yoluyla elde edilen Poliamid 6 (PA6) ipliklerin ve bu ipliklerden üretilen dokuma kumaşların fiziksel, elektromanyetik ve optik özellikleri üzerindeki etkisini araştırmaktır. Çalışma kapsamında; farklı oranlarda (%0,05-0,10-0,15) Ti nanopartikül katkılanmış PA 6 nanokompozit tekstüre iplikler (70 denye, kesitte 24 filament) üretilmiş ve deneysel olarak karakterize edilmiştir. Kontrol kumaş üretimi için Ti katkılanmamış standart PA 6 multifilament iplik de üretilmiştir. Sonuç olarak, Ti nanopartikül katkılama, PA 6 multifilament ipliklerin ve dokuma kumaş örneklerinin mekanik özellikleri üzerinde düşük seviyede anlamlı bir etki göstermiştir. Uygulanan Ti katkılama oranlarının, kontrol kumaşa göre katkılanmış kumaş örneklerinin elektromanyetik koruma etkinliği (EMSE) değerleri üzerinde anlamlı bir etkisinin olmadığı belirlenmiştir. Uygulanan oranlarda Ti katkılama, kumaş örneklerinin optik geçirgenliğini azaltma yönünde etki etmiş, dalgaboyu büyüdükçe bu etki artma eğilimi göstermiştir. Uygulanan katkılama oranları optik soğurma üzerinde pozitif yönde bir etki göstermiştir.

Published: October 2023

In this study, it is aimed to investigate the strength performance of slag-based geopolymer mortar with different percentages of silica fume and colemanite waste by mixing Na₂SiO₃ and NaOH as the alkaline activator for the geopolymerization reaction, and cured at room temperature were prepared, in terms of compressive strength, flexural strength, ultrasonic pulse velocity and freeze-thaw resistance parameters. Five different mixtures were prepared by using different amounts of silica fume and colemanite waste by using the same amount of ground granulated blast furnace slag, sand and 8M sodium hydroxide for these five mixtures. The mixture, including a paste proportion of 20% slag, 40% colemanite waste, and 40% silica fume, was used as a control mix. The maximum compressive strength (21.24 MPa, 38.32 MPa) flexural strength (5.86 MPa, 6.98), weight loss caused by freeze-thaw effect (0.56%) and ultrasonic pulse wave test (3082 m/s) results were noted as for 7th and 28th day, respectively. After -60 cycles [1 cycle consists of (-18 oC) for 90 minutes and (+4 oC) for 30 minutes], the maximum compressive and flexural strength was observed as (40.18 MPa and 4.92 MPa, respectively). The results indicated that the strength results were consistently increased as silica fume increased. The addition of a certain amount of silica fume gave promising results both in terms of the strength and durability aspects. Overall, according to this experimental study, the utilization of 30% colemanite waste and 50% silica fume can be recommended so as to balance both sustainability and engineering aspects.

In a practical scenario, only a modest amount of distilled water can be generated each day by a basic solar still with a single basin. Fin-type solar ponds, fin-type solar stills, and integrated fin-type solar stills with finned ponds are investigated. The theoretic performance and experimental studies on the proposed systems were carried out in Pongalur near Tirupur (10.9729° N, 77.3698° E), a region with a latitude of 10° north. Single basin solar still (SBSS), single basin solar still with fin, single basin solar still with pond, single basin solar still with finned pond, and integrated single basin fin-type solar still with a finned solar pond were developed. Adding fins to the small solar pond enhanced the thermal performance of SBSS, by increasing the daily water collection. The pace at which heat is transmitted from the basin to water has risen due to the fins. According to this study, the amount of water collected by single basin solar still with fin, single basin solar still with finned pond, and integrated single basin solar still with fins and finned pond grew by 46, 48, and 52% for each of these systems.

Pulsed electric field (PEF) technology has attracted considerable attention because it can efficiently treat pollutants that are difficult to degrade. In this study, a PEF system using iron as the electrode was constructed to investigate the effect of PEF–Fe on the growth and metabolism of aerobic denitrifying bacteria and the effectiveness of wastewater nitrogen removal. The chemical oxygen demand, NO3-–N and nitrate removal rates were 98.93%, 97.60% and 24.40 mg·L−1·h−1, respectively, under optimal conditions. As confirmed in this study, PEF–Fe could improve the key enzyme activities of W207-14. Scanning electron microscopy revealed that the surface of PEF–Fe-treated W207-14 was intact and smooth without any irreversible deformation. Flow cytometry combined with fluorescence staining analysis also confirmed reversible electroporation on the cell membrane surface of PEF–Fe-treated W207-14. Differentially expressed gene enrichment analysis showed that PEF–Fe activated the transmembrane transport function of ATP-binding cassette transporte (ABC) transport proteins and enhanced the cell membrane permeability of aerobic denitrifying bacteria. The significant differential expression of iron–sulphur cluster proteins facilitated the regulation of electron transport and maintenance of the dynamic balance of iron ions within the PEF–Fe system.
Pegmatite fields of São Pedro de Ferros, Antônio Dias and Marilac, Minas Gerais State, Brazil: petrographic characterization
Authors: Costa Raphael
Published: October 2023

Pegmatites are rocks of granite or metastatic origin with gigantic crystals that are formed in fluid phase of the magmatic liquid enriched with incompatible elements, thats why they can be considered as gemstones and industrial minerals deposits. Both studied areas in the present article were genererated by anatexia process or partial fusion. The Jatobá Mine in the Pegmatitic Field of Ferros-Antônio Dias, in Santa Maria de Itabira, explores the aquamarine gem, a beryl variety, in a pegmatite that is located closer to the granite system of the quartz core and is docked in a gnaisse granitic rock from the Guanhães Complex. The collected sample was denominated like Quartzo alkali feldspar sienite in the Diagram QAPF. The blue color of the beryl is given by the intrusion of Fe. The Duas Cores Mining represents the Pegmatitic Field of Marilac, near Governador Valadares, and the exploration of bi-color tourmaline will begin soon. This mineral is in a very weathered pegmatite, positioned more at the end of the granite system and docked in the mica-schist rock of the São Tomé Formation. The sample was named Tonalite by the QAPF Diagram. The color variation of the explored gem is related to the enrichment of the Li element at the site.
IMPLICAÇÕES DA CONTRARREFORMA DO ENSINO MÉDIO NA EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA BRASILEIRA
Authors: De Sousa Sampaio Fabrício
Published: October 2023

A contrarreforma educacional em curso objetiva reorganizar os currículos e direciona a educação brasileira para determinado sentido e finalidade capitaneados pelo empresariado do país e pelos organismos internacionais. Partindo do questionamento sobre os principais efeitos que a atual contrarreforma  educacional possa reverberar na educação profissional e tecnológica brasileira, esta pesquisa qualitativa bibliográfica e documental objetiva identificar e analisar os efeitos dessa contrarreforma na estruturação, organização e finalidade da EPT. Dentre os resultados parciais, podemos afirmar que a implementação da recente contrarreforma recupera a dualidade e a fragmentação do ensino médio, objetivadas por reformas anteriores e, fundamentalmente na EPT, desmonta o ideário da formação humana integral através da: ressignificação, hibridismo e esvaziamento de conceitos importantes para a defesa dessa modalidade; a educação para o empreendedorismo e a precarização da formação docente ao permitir o notório saber.

Published: October 2023

Neste artigo, apresentamos a história da implantação do Ginásio Estadual de Floraí – no estado do Paraná –, em 1959, e o processo histórico de formação da cidade. O município, que tinha menos de cinco anos de emancipação política quando a escola foi estabelecida, teve nessa uma aliada, na solidificação da estratificação social. A maior parte da população vivia ainda na zona rural e não havia transporte escolar para que as crianças pudessem chegar à cidade e a escola. A implantação de escolas fazia parte do plano de (re)ocupação dos espaços chamados “vazios”, os quais deveriam ser preenchidos para que pudessem ser produtivos economicamente. Assim, iniciou-se o maior ciclo de migração para o Norte/Noroeste do Paraná, com vendas de terras por companhias privadas alinhadas ao governo, as quais colonizaram ou recolonizaram regiões ainda não anexadas pela exploração capitalista no estado.
