Authors: Romero Stephanie , Hazera Nicole
Published: March 2023

Siempre es una constante, revisar y mejorar en las guías curriculares para la cátedra de diseño gráfico. Plantear un aprendizaje transversal que estimule a construir nuevos conocimientos, una meta. Tomando como referencia a los autores Sergio Tobón y Juan A. García Fraile, quienes en sus textos mencionan que aplicar nuevas estrategias puede ser interesante, pero que, se debe sin embargo realizar bajo el enfoque de los contenidos y de las competencias como metas requeridas, para no desviar el objetivo, emprendimos la búsqueda de aplicaciones en red, para encontrar como recursos de asistencia, las herramientas tecnológicas adecuadas que permitan realizar clases invertidas apoyándonos en las nuevas tecnologías y las redes sociales. Se realizó una investigación documental, buscando en redes, blogs, páginas web, libros y prácticas con grupos experimentales con promedio de 8 a 12 alumnos universitarios en diversos espacios de tiempo.

Innovation is presented as the competitive weapon by which companies respond to the challenges of a dynamic environment. However, devising a strategy that balances the needs for short-term profitability and long-term survival becomes more complex when it comes to small and medium-sized businesses. Their limited resources, both in terms of human capital and financial means, hinder the development of organizational ambidexterity within these structures. The contribution of our qualitative study is manifested through the detection of the mechanisms enabling the SME to respond to the dual requirements of exploitation innovations and exploration innovations, particularly in a turbulent environment. We are therefore interested in the market of dermocosmetic products because it represents a young and growing market. The results obtained from the in-depth analysis of two cases, show that the simultaneous pursuit of these two imperatives is possible under certain conditions. We highlight three prerequisites: The necessity to rethink management and to conduct a new organizational and strategic adaptation process; The promotion of a culture and a social context stimulating ambidextrous behavior; Maintaining strong relationships with stakeholders.

Leer noticias en las que se reconocen derechos a los ríos como el “Atrato” en Colombia, el río “Ganges y Yamuma” en India, el río “Yarra” en Australia el río “Te Urewera” en Nueva Zelandia, o el reconocimiento de la amazonía colombiana como sujeto de derechos y en el ámbito nacional tenemos el proyecto de ley N°06957/2020-CR, a través del cual se pretende “reconocer que la madre naturaleza, los ecosistemas y las especies son titulares de derechos y sujetos de protección por parte del Estado, por tratarse de entes vivos, con valor intrínseco y universal, que tienen derecho a existir, desarrollarse naturalmente, regenerarse, restaurarse y evolucionar” y a nivel local tenemos la ordenanza Municipal  N° 018-2019-CM-MPM/A del 23 de setiembre del 2019 Reconoce a “la cuenca del río Llallimayo como sujeto de derecho con el fin de institucionalizar y generar los mecanismos y estrategias municipales que garanticen la conservación y gestión sostenible en beneficio de la población y de los ecosistemas” y la Ordenanza Distrital N° 006-2019-MDO/A del 26 de diciembre de 2019 en cuyo Artículo 1° reconocer a la madre agua-Yaku-Unu Mama como un ser viviente sujeto de derechos en todas sus formas: puquios, manantiales, ríos, lagunas, lagos. Nos provoca la siguiente pregunta: ¿es el momento histórico para incorporar constitucionalmente derechos a la naturaleza? ¿Es el momento histórico para incorporar principios que cimienten un biocentrismo? Es pues una tarea pendiente que debe ser debatida nuevamente en nuestro futuro próximo.
Confucian Inheritance in Nguyen Trai’s Thought – Its Characteristics And Meaning in Today’s Era
Authors: Ngoc Uyen Phan Thi , Minh Ho Chi
Published: March 2023

Nguyen Trai (1380 – 1442) was a great thinker of Vietnam in the late fourteenth and early fifteenth centuries. His thought was formed and developed in the tumultuous historical period of Dai Viet society with the task of defeating the invading Ming invaders, protecting national independence and territorial integrity. Besides, his thought is also the inheritance and fusion of Vietnamese social traditions with the philosophy of Confucianism, Buddhism and Taoism. In which, Confucianism is the theoretical foundation of Nguyen Trai. Nguyen Trai inherited and renewed the theories of traditional Confucianism to suit the social reality at that time, in order to carry out the task of saving the country and the people. Today, the contents of Confucianism inherited and transformed by him still have certain values in the cause of building Vietnam today.

Published: March 2023

Developing countries are undergoing rapid urbanisation to fulfil the high demands of incremental population growth, construction, and development. Excessive development has negative impacts on biodiversity by altering or destroying habitats. However, each bird species may respond differently to habitat alteration. Therefore, this study was conducted to determine the distribution of urban bird species in metropolitan cities and nearby areas in Peninsular Malaysia. The main objective of this study was to determine the distribution patterns of six aesthetically valuable urban bird species (Black-naped Oriole [Oriolus chinensis], Yellow-vented Bulbul [Pycnonotus goiavier], White-throated Kingfisher [Halcyon smyrnensis], Pink-necked Green-Pigeon [Treron vernans], Coppersmith Barbet [Psilopogon haemacephalus] and Common Iora [Aegithina tiphia]) in Greater Kuala Lumpur (the Klang Valley region) using observations from a citizen science (eBird) database. We mapped species abundance throughout the focal area using ArcGIS and analysed the data using Minitab. Three urban bird species dominated, with the highest number of observations recorded: Yellow-vented Bulbul (46.59%), Pink-necked Green-Pigeon (19.25%), and Black-naped Oriole (13.00%). While, the Coppersmith Barbet had the lowest recorded observations (2.76%). Species abundance differed significantly across the study region (F=5.12,p<0.05), with the studied species’ occurrence increasing as green spaces increased. Such dynamic mapping is crucial for better understanding the mechanisms of the persistence of urban biodiversity. We suggest creating more green areas and planting roadside trees to provide green corridors within cities to help sustain urban biodiversity.

As a generalization of pseudoorders, the weak pseudoorder in ordered (semi)hyperrings was defined by Qiang et al., and some results were studied. In order to further study, we apply weak pseudoorders for an ordered superring R and show relations with pseudoorders of R. Moreover, we present some illustrative examples and regular equivalence relation σ on ordered superring R, such that R/σ is an ordered superring. Furthermore, we show that if η is a weak pseudoorder on an ordered superring R, F is the set of all weak pseudoorders on R/η* and E = {ζ | ζ is a weak pseudoorder on R such that η ⊆ ζ}, then card (E) = card(F).

Published: March 2023

Introduction: The influence that academic life exerts on lifestyle of university students is a recognized fact. As a strategy adopted to prevent the massive spread of the SARS-CoV-2 virus, the Argentinian government decreed isolation and social distancing measures in 2020 that led to the cessation of attendance by students at universities; therefore, this particular situation represented an unknown scenario. Objectives: To evaluate changes in habits eating and physical activity (PA), in the context of confinement by COVID-19, in students of the Universidad Nacional del Litoral. Materials and Methods: A cross-sectional, observational and descriptive study was carried out from June to August 2020. An online questionnaire was used to investigate demographic data, diet and PA, developed ad hoc and validated by experts (reliability: Cronbach's alpha=0.85) and pilot test. The population sample (non-probabilistic method) included 1259 students, 22 ± 3 years old, predominantly female (78%). Results: 63% lived in the same place as during the attendance and 96% were accompanied. Moreover, 63% perceived that confinement measures modified their relationship with food, mostly for emotional reasons (71%). On the other hand, 81% increased their consumption of homemade meals and 26% used delivery more frequently. 49% of the students described their diet as moderately healthy; the majority (71%) ate all four main meals, and among those who skipped at least one (29%), the main reasons were not being hungry (38%) and getting up late (34%). Among those who drank alcohol, 56% consumed less. In other matters, 62% decreased physical activity and 20% maintained it. Conclusions: Social confinement had a negative impact by decreasing physical activity, while diet was modified by both negative and positive aspects. This information is valuable to capture interventions aimed at maintaining healthy lifestyles in this university population. Keywords: COVID-19 lockdown; college students; feeding; physical activity.

Introduction: In the field of foodborne diseases, Salmonella spp. can cause salmonellosis through foods such as chicken eggs, a basic food component, of which various qualitative parameters can be evaluated. The objective of the study was to evaluate the quality and the presence of Salmonella spp. in eggs sold in Libertador San Martín, Entre Ríos. Material and methods: The study was developed in the Nutrition Laboratory of the Universidad Adventista del Plata in Libertador San Martín, and a Chemical Analysis Laboratory in Paraná, from May to August 2020. The design was descriptive, retrospective and cross-sectional. The sample consisted of 114 eggs obtained from 3 local supermarkets, in which all egg suppliers in the city were represented. Results: Salmonella spp. wasn´t isolated in none of the samples analyzed. Each unit was clean, although 49 did not present centric yolk, being 57.01 % (n = 65) of A quality, with respect to the shell and content. The average weight was 56.89 g, with a predominance of large eggs, SD ± 3.72. For the shape index, the mean was 74.71, SD ± 2.45, highlighting those with optimal shape. With reference to the flotation test, most were fresh from the day. Regarding the yolk index, the mean was 0.38, SD ± 0.09, with the majority classified below B quality. There was a statistically significant relationship between this last parameter and the state of the shell and content (p = 0.010). The average pH of the white was 8.8, SD ± 0.39 and of the yolk 8.0, SD ± 0.71. Conclusions: The qualitative and microbiological parameters are acceptable, except the index and pH of the yolk. It is essential to continue ensuring the safety of the egg. Keywords: Foodborne diseases; Salmonella; safety.
A ESCOLA E A EDUCAÇÃO DEMOCRÁTICAS: UMA QUESTÃO PENDENTE NO CONTEXTO MOÇAMBICANO E UM DESAFIO ATUAL
Authors: Mechiço Rosa Alfredo
Published: March 2023

Relativamente à eventualidade da escola e a educação democráticas serem tomadas como uma questão pendente no contexto Moçambicano e um desafio actual interessa, antes de tudo, ressaltar que para a percepção do estágio actual da educação e escola moçambicanas, sobretudo a pretensão de edificarem-se e consolidarem-se como democráticas, é essencial levar em linha de conta que a escola e a educação democráticas constituem alguns dos instrumentos de consecução de uma sociedade democrática, a medida que universalizam o saber sistematizado e, igualmente, permitem a convivência democrática através da vivência de experiências democráticas, essenciais para o exercício da democracia. Concomitantemente, a medida que a democracia capitaliza experiências democráticas no processo educacional, a agência escolar se torna um vector real da democracia. Dado que a consolidação da democracia e da cidadania democrática passa, inevitavelmente, por uma educação-formação democrática, o grande desafio para o Estado moçambicano prende-se com o facto de tomar como prioridade e urgente a necessidade de investir-se na escola como agência de formação democrática, isto é, tomá-la na qualidade de factor gerador de competências e habilidades democráticas, tais como o diálogo, a liberdade de expressão, a participação, a tolerância, a solidariedade, a cooperação, o respeito pelas diferenças,  etc.
RELEVÂNCIA CURRÍCULAR NO ENSINO BÁSICO: DAS SILHUETAS À PERFORMATIVIDADE NA ESCOLA
Authors: Sapane Benedito
Published: March 2023

A presente reflexão questiona a relevância curricular do Ensino Básico em Moçambique a partir de uma abordagem hermenêutica. Ela problematiza os instrumentos de regulação veiculados por especialistas e técnicos de educação e pelos actores educativos na escola, com vista a sustentação da “fabricação e modelação do professor.” Assim, nesta reflexão se assume a ideia segundo a qual torna-se relevante examinar os documentos produzidos pelas instâncias centrais da educação para a implementação das políticas educativas e, por conseguinte, perceber de que forma eles podem produzir formas de regulação da autonomia docente nas escolas, tencionando a relação entre o currículo escrito, as políticas de avaliação e a autonomia docente. Para tal, nesta abordagem toma-se em linha de conta a tese da qual a exposição dos referidos contornos (silhuetas) permitirá a explicitação da relevância do currículo do Ensino Básico em Moçambique, considerando os pressupostos conceptuais, epistemológicos e pedagógicos que lhe são inerentes.
MATRIZES MÍTICAS E IMAGINÁRIAS DA PEDAGOGIA DA ESPERANÇA DE PAULO FREIRE

Published: March 2023

Este artigo visa, muito mais do que apresentar o conteúdo da Pedagogia da Esperança em Paulo Freire, identificar os traços míticos e imaginários que se escondem sob o viés de uma racionalidade que caracteriza o discurso pedagógico. Em outras palavras, identificar, na perspectiva de Paulo Freire, a produção simbólica (porque todo discurso é sempre simbólico) das imagens que dão conta da constituição do sentido da ação de Freire.

It becomes important to identify these diseases at an early stage to prevent their spread.
A Systematic Review on Anomaly Detection
Authors: Jaiprakash Prajapati  , Prof. Nilesh Choudhary
Published: March 2023

Anomaly detection has been used for many years to perceive and extract anomalous points from data. This is an important question that has been explored in various research areas and application domains. Many anomaly detection techniques are specifically designed for specific application domains, while others are more general. Many data science strategies had been used to come across anomalies. One widely used technique is deep machine learning, which play an important role in this field. This research paper provides a systematic literature review analysing ML models for detecting anomalies. Our review analyses the models from four perspectives: the Problem nature and challenges, Classification and formulation, Review of past work, and the future opportunities. When applying a given technique to a particular domain, these assumptions can be used as guidelines to assess the effectiveness of the technique in that domain. We also discuss the computational complexity of the technique, as this is an important issue in real application domains. We hope that this paper will provide a better understanding of the different directions in which research has been done on this topic, and how techniques developed in one area can be applied in domains for which they were not intended to begin with.

Nihonggo No Benkyou: The Case of Filipino ESL Teachers in Graduate School
Authors: Lumabi Bethany Marie
Published: March 2023

In 2010, the Commission on Higher Education (CHED) institutionalized the offering of foreign languages in the curricular programs of higher education institutions to accord global acceptance of local graduates in the Philippines. In graduate school, Nihongo is one of the foreign languages commonly offered in the local university.  Theoretically, the second language acquisition of adult learners (i.e., graduate students) is crucial and different from adolescent language learners. And there is a dearth of literature on Filipinos learning Nihongo; most of them involve college students and overseas Filipino workers (OFWs) and less among ESL teachers in graduate school. This study: (1) contributed to the limited evidence in Japanese language learning of Filipino students; showed qualitative evidence on the CPH of adult learning a third or fourth language. Results revealed that though most of the ESL teachers in graduate school were middle-aged, they partly considered their age crucial in learning Nihongo and declared that their age was not the only factor in recognizing their difficulties in learning a foreign language rather other learning limitations such as affective factors, learning environment, workload, etc.; (2) presented the ESL teachers’ difficulties in learning Nihongo language in the graduate school such as writing and translating sentences and phrases, vocabulary and pronunciation; and (3) showed their strategies in learning the Japanese language as an academic requirement were creating mental linkages, applying images and sounds, reviewing well, and employing actions. Thus, this study presented recommendations for the effective teaching of Japanese language among graduate students in the Philippines.
Estado de exceção, política do inimigo e (des)politização por meio das barreiras visíveis e invisíveis aos migrantes internacionais
Authors: Silva Bianca Guimarães , Villarroel Ivette Esis , Rocha Thiago Gonçalves Paluma
Published: March 2023

As barreiras físicas ou morais aos migrantes escancaram as tensões envolvendo o fluxo migratório. Nesses espaços, questiona-se a existência de regimes de exceção em concomitância com a democracia. Atestou-se o uso de artifícios como a securitização das fronteiras, o confinamento dos indocumentados e a construção da identidade do migrante como criminoso para condenar migrantes à vida nua, despolitizando-os como sujeitos políticos. Este estudo além das teses de Agamben, também utiliza a concepção de inimigo político, criada por Schmitt, para compreender a exclusão dos não nacionais. Deste modo, associa-se valor aos migrantes apenas por sua utilidade econômica. Identificou-se a existência de campos de exceção nas democracias liberais. Esses locais atestam as contradições existentes entre a pretensão de homogeneidade nacional e o multiculturalismo na era da globalização. Justificam-se, por meio do medo do contato com o diferente, a construção de muros e a despolitização de sujeitos políticos.
Application of Realistic Mathematics Education (RME) To Improve The Students’ Mathematical Communication Ability
Authors: Harahap Irham Habibi , Sari Dwi Novita
Published: March 2023

This article will discuss the communication skills of SMP IT Al Ikhwan students in class VII-1 and VII-2 each with a total of 32 students, after being given learning through RME. Determination of the sample is done by simple random. The research instrument used in this study was a test that was statistically analyzed using N-Gain. After carrying out a series of activities starting from the pretest, treatment and posttest, it can be concluded that the use of RME was apparently good for improving mathematical communication skills as seen from the N-Gain acquisition for each class that was sampled. The learning process that uses RME opens opportunities for students to be able to play a more active role in expressing themselves in solving mathematical problems and realistic mathematics education gets a very good response, students really like it and feel very excited.
Social and spatial impacts of changing urban form in Ayazağa, Turkey
Authors: Kırtaş Emine Ecem , Tomruk Banu
Published: March 2023

The politics of spatial reproduction have been at the heart of Turkey’s economic growth over the past two decades, accelerating rapid urban change in İstanbul. In addition to the transformation of the existing building stock in the city, natural spaces are also being developed through the partial revision of master plans and reproduced through large- scale new investments. This study examines the spatial changes in the Ayazağa Neighbourhood on the northern periphery of İstanbul. The region has become one of the areas where large capital owners have invested extensively in the last decade. Most of the new spatial interventions are large- scale mixed- use buildings. Based on morphological analysis and in- depth interviews with residents, the study investigates the existing urban fabric and the new interventions through four specific cases. The reproduction of urban space in the case study areas is discussed in terms of spatial characteristics and social aspects. As a result, the lack of public open spaces, massive new buildings with privately owned public spaces, and the social and spatial segregation between the residents of the informal settlements and the new upper- class housing are addressed as problem areas.

Rwanda’s economy is inextricably linked to its water supply, with agriculture employing nearly 70% of its population and making up half of the country’s export revenue. It aspire to become an upper-middle-income country by 2035, and a high-income country by 2050. But rising temperatures and more prolonged dry spells threaten crop production and strain water supply. Rwanda’s Vision 2050 policy details the country’s long-term goals and provides the planning blueprint to guide Rwanda’s development. But such growth, coupled with climate change, will profoundly affect its water supply and demands. Gaining a clearer understanding of the changing water supply and demand, as well as the nexus between water, energy, and food production, is critical to Rwanda’s success. The Water Resources Group (2030 WRG) is a public-private-civil society partnership hosted by the World Bank to help governments balance water security with longterm development and economic growth. The recently established Rwanda Water Resources Board (RWB), the Ministry of Agriculture and Animal Resources, and Ministry of Environment tasked the 2030 WRG in 2020 with performing a Hydro-Economic and Climate Change Analysis (HECCA), with the following directives: 1. Conduct a strategic assessment of the water sector that demonstrates how water and the economy are inter-linked; 2. Recommend concrete actions toward sustainable water resources management; and 3. Support a dialogue to identify and align joint initiatives among sectors, both public and private, towards sustainable water resources management, and enable long-term economic growth through 2050.
Epidemiology and subtype distribution of Blastocystis among asymptomatic volunteers in Korea: a multicenter study
Authors: Kim Seong Hoon , Byun Jung-Hyun , Oh YeJin , Liu Changseung , Bae Mi Hyun , Won Eun Jeong
Published: March 2023

Background: Blastocystis is a genus of intestinal, anaerobic protozoan parasites that can be isolated from humans, animals, and the environment. We aimed to determine the distribution of Blastocystis and subtypes (STs) using stool samples obtained from healthy volunteers at collection centers in Korea. Methods: A total of 478 stool samples from volunteers were collected at five collection centers throughout Korea. The presence of Blastocystis was determined using PCR based on the small subunit (SSU) rRNA gene, and Blastocystis STs were confirmed through sequencing of the SSU rRNA gene. Results: Molecular analysis revealed the presence of Blastocystis in 27 (5.6%) of the enrolled participants. Two STs were identified: ST3 (66.7%) and ST1 (33.3%). The positive rates of Blastocystis varied by geographical region, ranging from 1.2%–12.0%. ST3 was the predominant subtype in all centers except one, where only ST1 was isolated. Phylogenic analysis showed clustering based on ST, but no significant differences were found among the regions. There was no association between Blastocystis colonization and either age or sex of the participants. Conclusions: The results of this multicenter study demonstrated colonization by Blastocystis, mainly ST3, in the gastrointestinal tracts of asymptomatic individuals in Korea.

Background: A bloodstream infection is a life-threatening medical emergency, with a mortality rate of up to 30%. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) can be used to identify pathogens directly from positive blood cultures. Two commercial preparation kits, SepsiTyper (Bruker Daltonics, Germany) and SepsiPrep (ASTA Corp., Korea), and two MALDI-TOF MS systems, MALDI Biotyper Sirius (Bruker Daltonics, Germany) and VITEK MS PRIME (bioMérieux, France), are available in Korea. We examined these kits and MALDI-TOF MS systems to analyze their performance. Methods: We assessed the effectiveness of direct identification using 47 blood cultures and 3 bile cultures positive for microbial growth. The VIRTUO system (bioMérieux, France) was used to incubate the samples after they were collected in Bact/ALERT aerobic and anaerobic bottles. The manufacturers’ protocols were followed for both the SepsiTyper and SepsiPrep kits. Results: The SepsiTyper yielded considerably more accurate identifications than did the SepsiPrep, when utilized in MALDI-TOF MS systems (P = 0.0044). However, the SepsiPrep was easier to use and the results more quickly obtained than with the SepsiTyper. The MALDI Biotyper Sirius produced more accurate identifications with the SepsiTyper than did the VITEK MS PRIME (P = 0.0736). The SepsiTyper enabled the accurate identification of five of six polymicrobial cases, utilizing either the MALDI-TOF MS systems. Conclusions: Among the pathogen ID kits tested in this study, the SepsiTyper with MALDI Biotyper Sirius performed the best. In clinical laboratories utilizing VITEK MS PRIME, it is recommended that the either the SepsiTyper or SepsiPrep kit be used for direct identification, while considering certain limitations in terms of performance.

Бидай дақылының тіршілігінде жапырақ, сабақ, масақ және тамыр массасының өсіп-дамуы маңызды роль атқарады. Оның көлемі болашақ өнім құрылымы мен сапасын анықтайды. Сондықтан, танаптық зерттеу жұмыстары жаздық жұмсақ бидай сорттарының биомасса қалыптастыру сипатын, оларға агротехникалық шаралардың әсері мен сорттар арасындағы ерекшеліктерді анықтауға бағытталды. Бидай дақылының жапырақ массасының максимум деңгейі масақтану кезеңіне, ал жалпы құрғақ биомассаның максимум деңгейі балауызданып пісу кезеңіне сәйкес келді. Биомасса қалыптастыру ерекшеліктері бойынша жаздық бидай сорттарында (Айна, Гранни және Шортандинская 2012) генотиптік өзгешеліктер ± 24,78 пайызға дейін ауытқыды және түзілетін өнім деңгейіне жоғары корреляциялық байланыстың болуымен (P < 0,05, r =0,52-0,94) ерекшеленеді. Жаздық жұмсақ бидай сорттары қалыптастырған биомасса өнімнің құрылымдық элементтерінің салмақтық өлшемдеріне тығыз корреляциялық байланыстың болуымен (1 масақтағы дән массасы P < 0,05, r = 0,51-0,85 және 1000 дәннің массасы P < 0,05, r = 0,4-0,57), ал сандық көрсеткіштеріне (өсімдік биіктігі - r = -0,19-+0,17; өнімді түптенуі - r=-0,12 +0,24; масақ ұзындығы - r=0,12-0,24) әлсіз тәуелділіктің болуымен сипатталды. Жаздық бидайдың орта мерзімде пісетін сорттарының биомасса қалыптастыру деңгейі ауа-райына, қолданылған агротехникалық шаралар мен қоректену жағдайына тікелей тәуелді болып келеді. Ылғалды жылы жаздық бидайдың орта мерзімде пісетін сорттарын ерте мерзімде (Орталық Қазақстан өңірі үшін 15 мамыр), жоғары мөлшермен сеуіп, кешенді тыңайтқышты енгізгенде (Айна - 7258 кг/га, Грани -7903 кг/га, Шортандинская 2012 - 7406 кг/га) максималды биомасса қалыптастырады, ал құрғақшылық жылдары орта және кеш мерзімде (Орталық Қазақстан өңірі үшін 20 мамыр), ұсынылған мөлшердің минимальды немесе орта мөлшерімен сеуіп, тек фосфор тыңайтқышын енгізгенде максималды мол биомасса (4258-4915 кг/га) түзеді.

Alat penukar kalor adalah alat yang digunakan untuk memindahkan panas dari sistem ke sistem lain tanpa perpindahan massa dan bisa berfungsi sebagai pemanas maupun sebagai pendingin. Biasanya, medium pemanas yang dipakai adalah air yang dipanaskan sebagai fluida panas dan air biasa sebagai air pendingin (cooling water). Petrokimia Gresik memiliki alat penukar kalor tipe cangkang dan pipa (shell and tube) yang berfungsi sebagai pendingin pada proses absorpsi. Alat penukar kalor berfungsi untuk mengatur temperatur H2SO4 yang akan masuk ke absorber. Oleh karena itu, alat penukar kalor E-1303 dituntut untuk memiliki kinerja yang baik agar produk berupa H2SO4 diperoleh secara maksimal. Data yang digunakan berupa data desain dan data aktual dimana diperoleh tekanan turun pada cangkang (ΔPS) sebesar 9,5403 psi dan tekanan rendah pada pipa (ΔPT) sebesar 9,3537 psi untuk data desain serta nilai tekanan rendah data aktual pada shell (ΔPS) sebesar  9,4606 psi dan tekanan rendah pada pipa (ΔPT) sebesar 7,5972 psi. Hasil tersebut menunjukkan tekanan rendah yang didapat dibawah nilai penurunan tekanan. Oleh karena itu, dapat disimpulkan bahwa kinerja alat penukar kalor E-1303 berdasarkan data desain dapat dikatakan dalam kinerja yang baik dinilai dari aspek faktor pengotor (Rd) dan tekanan rendah.

In this study, Turkey and German state of North Rhine-Westphalia mathematics curriculum have been examined in the context of the algebra learning area. The learning outcomes have been investigated similarities and differences of the in terms of quantity and quality; classified in terms of knowledge and cognitive process dimensions of the revised Bloom's taxonomy. This study, in which the qualitative research approach was adopted, was carried out with the descriptive screening. Document analysis technique has been used in the data collection process. As a result of the analysis, it is determined that the learning outcomes are similar in terms of knowledge dimension; difference in terms of cognitive process dimension. While it is seen that the outcomes in the Turkey curriculum are in the analyze step as the highest cognitive level; Germany curriculum also includes outcomes fof higher level skills such as evaluate and create. Moreover, it is seen that the outcomes are mainly included in the procedural knowledge and apply step for both curriculums. Although it is seen that the outcomes in the Turkey curriculum are quantitatively higher than the outcomes in the Germany curriculum, it has been determined that the outcomes in terms of content are of a nature to cover each other. When the implementation suggestions were examined, it was seen that they were included in both curriculums in a detailed and rich way. On the other hand, when the distribution of the themes used in comparative education studies in the literature according to the countries was investigated, it was determined that the studies mostly focused on the elements of the curriculum (aim/goal, content, educational situations and testing situations). In the process of making sense of basic mathematical concepts and acquisition of high-level cognitive skills, teaching environments and programs can be designed by considering real life problems and process-based teaching models. On the other hand, since technology is a part of life, the education process can be integrated with digital games and/or stories, and programs and learning outcomes can be prepared in a way that includes teaching materials with digital content. In addition, different types of representation can be used in the mathematics teaching process and appropriate activities can be designed.
