Authors: YEŞİLÇİÇEK Tuncay
Published: November 2022

In this study, some basic biological parameters (e.g. sex ratio, condition factor, LWRs and LLRs) of G. artvinicus (Artvin gudgeon) inhabiting Borçka Reservoir and its tributaries from the lower Çoruh River Basin were investigated for the first time. Fish specimens were collected from June 2017 to May 2018 and totally 120 Artvin gudgeon (65 females and 55 males) ranging from 8.1 cm to 13.2 cm in TL were sampled. The sex ratio (F:M) was calculated as 1.18:1.00 in favour of females, but did not deviate from the expected ratio of 1:1 (χ²=0.834, P˃0.05). The total length-weight relationships were determined as W= 0.008TL3.159 (r2=0.971, P˃0.05) for females, as W= 0.012TL2.971 (r2=0.980, P˂0.05) for males and as W= 0.009TL3.088 (r2=0.970, P˃0.05) for all individuals. While the b-values which reflect the body shape were significantly different from the isometric growth indicating positive allometric growth for females and all individuals (Pauly’s t- test, P˂0.05). however, the b value of males did not differ from the isometric growth (b=3) pattern (Pauly’s t- test, P˂0.05). The slopes (b values) were found statistically significant for both sexes (ANCOVA, P 0.9) for each sex and relationship. Mean Fulton's condition factor values were calculated as 1.128±0.011 for females and 1.102±0.008 for males indicating a good growth condition in this habitat. The present study will provide a baseline on some biological parameters of G. artvinicus to provide a guideline for the fisheries management authority and fisheries scientists for further investigations as well as presents the first known reference on the LWRs and LLRs of this species for the FishBase database. Furthermore, the reported results will contribute to the conservation and sustainability of this species in the area.

This study aimed to determine the optimum stocking density that supported optimization of water quality and production of white shrimp (Litopenaeus vannamei) ponds. This study was conducted in 2 different cycles, namely cycles 14 and 15 and with different shrimp stocking densities in each cycle, namely 94 and 150 shrimp/m2. Each cycle and stocking density was represented by 2 ponds, namely ponds B5 and B6. Experimental animals used were white shrimp post-larvae stadia 9-10 (PL 9-10) with a size of 9-12 mm. Experimental parameters observed included water quality parameters (brightness, salinity, temperature, dissolved oxygen, pH, alkalinity, ammonium, and nitrite) and production performance (average body weight, average daily growth, biomass, feed conversion ratio, survival rate, and feed intake). Water quality of rearing medium reached the optimum value at a stocking density of 94 shrimp/m2. This was indicated by higher dissolved oxygen (4.0-5.3 mg/l) and lower ammonium (0.5-3.0 mg/l) compared to rearing ponds with a stocking density of 150 shrimp/m2 (4 0.0-5.0 mg/l; 1.0-3.0 mg/l). A stocking density of 94 shrimp/m2 showed a higher production performance than a stocking density of 150 shrimp/m2. This was indicated by the higher average body weight, average daily growth, and SR (18.20-19.77 g/shrimp; 0.30-0.48 g/day; 80.60-80.90%) and the lower FCR (1.11-1.33) at stocking density of 94 shrimp/m2 compared to 150 shrimp/m2 (17.18-17.40 g/shrimp; 0.45-0.50 g/day; 73, 92-78.32%; 1.64-1.75). The results of this study indicated that stocking density could affect water quality and shrimp production performance. The optimum shrimp stocking density in this study was 94 shrimp/m2.

Background: Diabetes will remain a threat to global health. No longer just a disorder of mature age, there is now a well-recognized trend towards the young. Early diagnosis leads to early intervention and prevention of complications in this susceptible but vital portion of the population. Objective: To compare the risk factors predisposing adults to early-onset (<40 years old) versus late-onset (≥40 years old) type 2 diabetes at the University of Santo Tomas Hospital from January 2015-December 2017. Methods: This is a retrospective review of medical records. All adult patients who fulfilled the inclusion criteria from January 2015 to December 2017 were included in the study. Data from charts were reviewed and analyzed. Results: The early-onset group had a mean age of 34 years, while the late-onset group had a mean age of 51 years. The early-onset diabetics were mostly obese, had higher HbA1c, worse lipid profiles, and had a positive family history of diabetes. Only a BMI of >27.50 kg/m2 was found to be a significant risk factor contributing to early-onset of diabetes. Myocardial infarction and nephropathy were more frequent in the late-onset group while retinopathy was more common in the early-onset group. Lastly, only retinopathy and neuropathy were significantly associated with longer duration of diabetes. Conclusion: The mean age of Filipinos was at least 5 years younger than the studies done on Caucasians. Most patients in the early-onset group were obese and had worse metabolic profiles. Retinopathy was more common in the early-onset group, while myocardial infarction and neuropathy were more common in the latter.
The Need to Vaccinate Against COVID-19

Globally, now in the third year of the pandemic, COVID-19 deaths have exceeded more than 6 million. As new subvariants emerge and spread, vaccines work to limit the worst of COVID-19 and continue to be important. Restraints are lifted, and COVID-19 may be seen as done for some, but COVID-19 is not yet done with others, no matter how badly everyone wants it to end. The SARS-CoV-2 pandemic has caused considerable morbidity and mortality worldwide. The protection provided by vaccines and booster doses offer a method of mitigating severe clinical outcomes and mortality. As debates over additional booster shots for COVID-19 intensify, many researchers are looking to the universal coronavirus vaccine model as a guide for managing future variants of SARS-CoV-2 and preempt the next COVID-19 surge.

Functional overload of teeth and implants is one of the most important reasons for their loosening and removal. Predicting the overload of teeth and implants is possible using digital technologies and special programs. Each study requires a basic study of functional stress indicators in an identical (preferably three-dimensional) mathematical model, as close as possible to clinical conditions.

The aim of the study was to study the maximum stresses in the hard tissues of the tooth and in the alveolar socket under vertical and inclined functional loads using three-dimensional mathematical modeling.

A differentiated analysis of the maximum integral stresses in a single-rooted tooth (mandibular canine) and the surrounding alveolar segment: enamel, dentin, cementum, cortical bone, spongy bone was carried out. A three-dimensional mathematical model of the segment was created, in which the fabrics corresponded to natural ones in their properties. A load of 150 N was applied to the cutting edge of the tooth in the vertical direction and at an angle of 45° from the buccal side. The maximum integral stresses according to Mises were analyzed.

According to the results of three-dimensional mathematical modeling in the hard tissues of the tooth, the maximum stresses under vertical and inclined loads are most significant in magnitude in enamel, then in dentin and in cement (with an inclined load, respectively, up to 77.610 MPa, 56.469 MPa, 15.832 MPa). An oblique load significantly increases the stresses in the hard tissues of the tooth and the surrounding bone compared to a vertical load (by 77.4% in the case of enamel). With a vertical load, the zones of maximum stresses in enamel and dentin are localized in the zone of the cutting edge, in cement – in the cervical and apical parts of the root; oblique load concentrates stresses in the cervical part of the tooth and the upper third of the root.

Stresses in the cortical bone tissue in the vertical direction of the load of the tooth are distributed along the tooth hole and along the outer surface of the jaw at the transition to the basal margin; with an oblique direction of the load, the stresses in the cortical bone are concentrated in the region of the neck of the tooth; maximum stresses under vertical and inclined loads 5.066 MPa and 27.909 MPa. Stresses in spongy bone tissue are recorded under the zones of maximum stresses in the adjacent cortical bone; maximum stresses under vertical and inclined loads 1.382 MPa and 4.375 MPa.
Afectos de la tristeza: representaciones del dolor/melancolía en Nocturno de Chile
Authors: Serrano Ezioly
Published: November 2022

Este artículo busca analizar la obra de Roberto Bolaño, Nocturno de Chile (2014), desde una perspectiva filosófica que parte de los planteamientos sobre las pasiones tristes o afectos de la tristeza, dolor/melancolía, que Baruch Spinoza señala en su Ética. Asimismo, se tomarán las ideas de “resentimiento” y “mala conciencia” esbozadas por Friedrich Nietzsche, a partir de las fuerzas activas y reactivas, para establecer una relación de continuidad entre los pensamientos de ambos filósofos sobre el dolor. De esta forma, y siguiendo esta línea de conexiones, este artículo toma como centro el personaje principal de la novela de Bolaño, Sebastián Urrutia Lacroix, como personificación literaria de un cuerpo colmado de dolor que se va descomponiendo entre el silencio y la literatura, a partir de los afectos y pasiones tristes mencionados por Spinoza y enmarcadas en la Mela-cholé: bilis negra, para, finalmente, convertirse en un “resentido” afectado por las fuerzas activa y reactivas de Nietzsche que se desdobla entre el joven envejecido y la culpa.
Nietzsche y Darío: una nota de lectura sobre el relato “El salomón negro”
Authors: Neme Sánchez Rauf
Published: November 2022

Esta nota de lectura examina la representación del filósofo Friedrich Nietzsche a partir del tópico del doppelgänger en el cuento fantástico “El Salomón Negro” de Rubén Darío. La asociación de Nietzsche como contraparte del bíblico y mítico rey Salomón proyecta en el fondo la percepción ambivalente de Darío sobre la influencia del pensamiento de Nietzsche para su generación.

O geossistema analisado se insere na Área de Proteção Ambiental do Lagamar do Cauípe, a qual possui dois corpos hídricos principais, sendo o maior o próprio lagamar e o segundo, localizado a norte e conhecido como lagoa ou Barra do Cauípe, próximo à foz de homônimo rio. No entorno desse complexo existe uma Área de Proteção Ambiental, criada pelo Decreto Estadual nº 24957 de junho de 1998, sendo uma Unidade de Uso Sustentável de acordo com a Lei nº 9985 de 2000. A área de Proteção Ambiental compreende ao todo 1884,46 hectares, sendo as suas porções mais ao sul compostas por embasamento cristalino inserido na Província Borborema, o qual é recoberto por material sedimentar tércio-quaternário na porção norte (a Formação Barreiras, criando os tabuleiros costeiros); e ao longo da faixa litorânea, ocorrem praias e dunas. Analisou-se nessa unidade de conservação os índices de qualidade das águas em quatro pontos específicos ao longo da área de proteção nos anos de 2020 e 2021, para tanto utilizou-se a portaria do Ministério da Saúde nº5 de 28 de setembro de 2017. A análise de uso e ocupação foi realizada através de visitação in loco com equipamentos específicos e auxílio de geoprocessamento digital com o emprego do software QGIS 3.16.16 para a produção das peças cartográficas; sendo estas elaboradas com o emprego de imagens satelitárias das constelações CBERS e LANDSAT. Os resultados indicam que há premente necessidade de ação fiscalizatória estatal na área de proteção, além do  ordenamento de usos e ocupações devido ao aumento da deposição irregular de resíduos sólidos, bem como por conta do declínio da pujança de qualidade vegetacional.
‘Chińczyki trzymają się mocno.’ Dynamika obrazu Chińczyka w Polsce (1988-2018)
Authors: Nowicka Ewa , Zhanaev Ayur
Published: November 2022

Artykuł jest poświęcony analizie kształtu i historycznej dynamice stereotypu Chińczyka w społeczeństwie polskim. Oparty jest na badaniach sondażowych zespołu Ewy Nowickiej (1988 i 2018) oraz na nielicznych wynikach badań ilościowych i jakościowych innych autorów. Wizerunek Chińczyka uznaliśmy za szczególnie interesujący w badaniach nad społecznym dystansem jako klasyczny stereotyp zbiorowości „obcego nieznanego”, zbudowany na informacjach pośrednich (głównie medialnych) a nie na wiedzy płynącej z kontaktów osobistych, gdyż są one bardzo ubogie (liczba przebywających na terenie Polski obywateli Chin w r. 2020 niewiele przekraczała 20 tys.). Mała wiedza o Chinach i sąsiadach tego kraju powoduje, że czasami Chińczycy są w społeczeństwie polskim pojmowani w sposób uogólniony, jako Azjaci. W takiej sytuacji społecznej stereotyp obcej grupy skonstruowany jest wokół wartości kluczowych dla kultury społeczeństwa stereotyp tworzącego. W polskim stereotypie Chińczyka dominuje bardzo pozytywnie w kulturze polskiej ceniona cecha „pracowitość” (i jej pochodne). Jest ona związana z trzecią co do częstości cechą – „uległością wobec władzy” (brakiem dążenia do wolności indywidualnej i zbiorowej), a także z drugą co do częstości wskazań grupą cech związanych z uprzejmością, spokojem i ugrzecznieniem. Na skali sympatii Chińczycy lokują się nisko – należą do kilku najmniej lubianych narodów i grup etnicznych. W ostatnich latach następuje wzrost pozytywnego wizerunku Chińczyka, co posiada ewidentny związek ze wzrostem ekonomicznego znaczenia Chin na świecie. To ostatnie zjawisko w odpowiedziach respondentów wyraża się nie tylko w kategoriach podziwu, ale też niepokoju. Badanie przeprowadzone w połowie roku 2018 ukazuje wizerunek Chińczyka w społeczeństwie polskim tak jak on wyglądał niedługo przed wybuchem pandemii COVID-19.
Sąsiad na płótnie malowany. Edukacyjno-informacyjny wymiar wystawy „Ukraina. Wzajemne spojrzenia”
Authors: Dębicki Marcin
Published: November 2022

Artykuł jest próbą przyjrzenia się sposobowi, w jaki w ramach wystawy artystycznej Ukraina. Wzajemne spojrzenia (prezentowanej w Krakowie od września 2021 do stycznia 2022 roku) skonceptualizowano owe tytułowe państwo, a także polsko-ukraińskie sąsiedztwo. W tym celu wyodrębniono dziesięć „zworników dyskursu”, ilustrując je przykładami stosownych eksponatów, niekiedy opatrując je także komentarzem historyczno-kulturowym i odnosząc do stosownych koncepcji teoretycznych. Drążąc edukacyjno-informacyjny wymiar ekspozycji, wpisano ją w ramy analizy treści, zadając sobie pytania: kto mówi poprzez wystawę, co, do kogo i w jakim celu? Zgodnie z zamysłem jej kuratorek, w analizie treści ekspozycji uwzględniono polską publiczność jako jej głównego odbiorcy.

Abstract

     The industrial revolution was not only in terms of machine technology but also developed into information technology, such as the internet and applications. Micro businesses are growing rapidly along with technological developments. Kementerian Koperasi dan Usaha Kecil Menengah (Kemenkop UKM) launched a total of 3.79 million micro, small and medium enterprises (MSMEs) that have used online platforms to market their products. This number is around 8 percent of the total MSME players in Indonesia, which is 59.2 million. Supporting the development of the Indonesian Institute of Accountants issued the Accounting Standards for Small Medium Enterprises in 2016 and effective January 2018. The UKM Ministry of Cooperatives followed up on the implementation of the standard by issuing applications for the preparation of microfinance reports under the Lamikro (Microfinance Report) in October 2017. September 2018 Lamikro has been downloaded more than 5000 downloaders. Convenience, simplicity and flexibility of the application attracts business people to use it. Lamikro's implementation on the achievement of these figures has not been said to be successful when compared to the 3.79 million business people who use online platforms especially if compared to 59 million micro-entrepreneurs in Indonesia. This essay aims to explore the potential of using Lamikro and offer alternative solutions so that the implementation of Lamikro effectively.
