The predicament of Turkish modern identity: The east-west oscillation in Snow
Authors: Brameswari Catharina , Iskarna Tatang
Published: July 2024

This research uses Orhan Pamuk’s Snow in order to reveal the tension and oscillation between the East and the West which is represented by Ataturk’s forced modernization on the restriction of veils in schools and public places. Pamuk uses Kars, a small city in Turkey’s border which always coved by snow, to describe this tension. The women are presented as the oppressed who silently end their life as their way to protect their beliefs and tradition as well as the weapon to fight against the oppressor. To dismantle Pamuk’s work that highlights the endless oscillation, I employ the method of library research by presenting the internal struggle experienced by the main characters that are forced to embrace Western tradition. This research deals with two issues namely oscillation and complex desire to imitate the Others experienced by the main characters the as well as the solutions to the predicament that are offered by Pamuk in Snow. This research is also accompanied by Said’s Orientalism and Bhabha’s Postcolonialism that are employed to illuminate the solutions. Additionally, the information on Turkey’s history and socio-politic condition are presented. This research is a way to show how the oscillation can be solved by embracing one culture without leaving the other. Additionally, it is also a tool to raise the readers’ awareness towards the problem on the predicament of the East and West and develop their critical thinking towards the forced modernity by the oppressor.

Folklore is a reflection of a society from which we can see how the society lives with various aspects of life including women’s images and roles. This study aims to describe (1) the comparison of structure of the two stories; (2) the comparison of the women’s images in the two stories; and (3) the comparison of the women's roles in the two stories. This study used a comparative qualitative descriptive method with comparative literature studies. Comparative literature studies were based on the comparison of the two stories to identify the similarities and differences with the support of the structuralism theory by A. J. Greimas. Besides, to examine the women’s images and roles, this study used feminist literary criticism. The data were folklore that has been documented in a book entitled Ni Anteh Pergi ke Bulan transcribed by Sukardi (2006) and The Bamboo-Cutter’s Tale transcribed by Kawauchi (2000) which was translated by McCarthy. The data were analyzed by describing the data, interpreting the data, and drawing conclusions. The results of this study indicated that the two stories: (1) have differences in terms of the structure of the story; (2) have similarities and differences in women's self-image and social image; and (3) have similarities and differences in the women’s roles. Based on the women’s images and roles presented in the stories, there is a feminist struggle that discourses on gender equality.

Code Mixing Used by English Lecturers in English Language Teaching (ELT) for Non-EFL Students
Authors: Fitria Tira Nur
Published: July 2024

This research is to know the type and reasons for code-mixing used by English lecturers in teaching non-EFL students at ITB AAS Indonesia. This research uses descriptive qualitative. The analysis shows that English lecturers use code-mixing during the English teaching and learning process by inserting Indonesian words, phrases, and clauses. In their utterances, they insert words consisting of parts of speech including pronouns, verbs, adjectives, adverbs, prepositions, and conjunction. They insert phrases including noun phrases, verb phrases, adjective phrases, and adverbial phrases. They also insert clauses including an independent clause. The lecturers use bilingualism such as code-mixing by using two languages both English and Indonesian in the delivery of learning materials and instructional instructions to avoid miscommunication. Therefore, code-mixing is felt to be very necessary to bridge communication in learning between lecturers and students. Practically, the use of code-mixing serves as a way to teach English more easily. Besides, other several reasons for using code-mixing in English language teaching are clarification of ideas and opinions, giving instructions effectively, translation points and notes, socialization and communication, showing linguistics competence, changing/shifting topics, ease of expression, emphasis, and highlighting points, checking understanding, repetitive functions, and create a sense of belonging.

Published: July 2024

Mindfulness is the basic human ability to be fully present, aware of where they are and what they are doing, and not overly reactive or overwhelmed by what is going around them. The growing evidence of the use of mindfulness practice on promoting psychological wellbeing and self-regulation is in line with the increasing use of mobile applications in this digital era nowadays especially during the COVID-19 pandemic era. This study aims to find out the influence of two mobile-based mindfulness apps, Calm and Headspace, on the pre-service teachers of English as a Foreign Language (EFL) in Indonesia studying online during COVID-19 pandemic era. The 43 subjects were given 20-session-mindfulness intervention (guided and independent trainings) using the two mobile-based mindfulness apps. The data from the Five Facet Mindfulness Questionnaire (FFMQ), the classroom observations, and the written interviews were analysed quantitatively and qualitatively. The results from the t-test analysis on the FFMQ show that there was an improvement on the subjects’ mindfulness level after the intervention. Furthermore, the results of the observation and the interview show that the oral narrations of the contents in the apps were found useful as a means to provide positive learning environment before and during the learning practice. Moreover, the oral narrations of the contents in the apps were specifically found useful as a means to practice listening comprehension. Therefore, besides being served as a means to practice and improve the pre-service teachers’ mindfulness level, mobile-based mindfulness apps could also be used to enhance one’s English listening comprehension skills. The use of mobile-based mindfulness applications can be promising for pre-service teachers in Indonesia who need to have balance academic and social-emotional skills to support their role in teaching students in the future.

Published: July 2024

The study of Indonesian language issues in higher education states that the low positive attitude of Indonesian citizens towards Indonesian language is the root of the birth of problems surrounding Indonesian language. Therefore, this study affirms the position of Indonesian in the global competition.  Through regular and serious efforts to increase vocabulary, the ability of Indonesian vocabulary in expressing intellectual thoughts or in the development of science, technology and art cannot be underestimated. This optimism is supported by the positive attitude of the Indonesian people towards the Indonesian language, the increase of groups who cannot speak Indonesian and groups who are not proficient in Indonesian, the dissemination of codification results (Indonesianization of foreign words and terms) to Indonesian speakers, and the publication of codification results and language development as much as possible. In addition, this study reveals the central position of Indonesian as a means of studying philosophy. This point is intended to further convince the academic community of the philosophy campus of the importance of Indonesian as a means of revealing cultural treasures, a means of logical consideration, and a means of personality development.

Published: July 2024

The plant is called tarum in Sundanese, nila in Sanskrit and indigo in English. This plant is considered a source of inspiration for place naming (toponymy) in Sundanese landscape. Some of the places and natural phenomena that are considered to be inspired by the tarum plant are Ci Tarum as the largest river in Sundanese landscape, Tarumanagara as the kingdom with the oldest epigraphic evidence in landscape Sundanese, and Pataruman which is historically believed to be the center of tarum processing activities that produce natural blue dye. There are still other variations of names with the word tarum, such as Tarumajaya located in the southern area of Bandung in the upstream area of Ci Tarum and Banjar Patroman (Banjar Pataruman) located in the eastern area of Priangan, which is believed by the surrounding community to be one of the centers of tarum processing in the past. The naming of places and natural phenomena is an important linguistic phenomenon in the cultural aspects of Sundanese society that requires critical, fundamental and analytical analysis. Thus, conceptual precision that relies on the meaning and basic meaning of tarum as a working tool for disclosing information and knowledge that is more holistic and comprehensive, is expected to open up insights and provide valuable contributions regarding the cultural construction and historical aspects of Sundanese society in the past in landscape Sundanese more clearly and accurately.

Authors: Sánchez González Jorge Juan
Published: July 2024

This research aims to examine humor as a pragmatic-social phenomenon applied to the use of two Greco-Latin formants with comic intention. This objective seeks to demonstrate the use of two elements with Greco-Latin roots in the formation of a humorous pattern that manifests itself in the virtual environment. To achieve this, both suffixes have been applied to lexical bases that are in principle unrelated to these elements. This research will provide a brief explanation of the suffixes -ina and -oide, commonly used in the scientific-technical field, but in this case they are adopted by speakers as a strategy to generate comedy in the virtual environment of the social network Twitter. Finally, the General Theory of Verbal Humor will be applied to the 756 tweets that make up the compiled corpus. A pragmatic analysis of the most representative texts in which both suffixes published on said platform are used will be presented and will serve as an example of such uses.

BACKGROUND: Postmenopause is accompanied by several body changes, including those in the immune system. Studying the molecular pathways linking the decrease in the level of sex steroids in the postmenopausal period with immune aging is important to completely understand the pathophysiology of immune aging, which will allow for accurate identification of potential therapy targets for autoimmune, oncological, cardiovascular diseases and prevention of infectious diseases in women during the postmenopausal period.
AIM: To compare cellular immunity and cytokine profile parameters in women during perimenopause and early postmenopause.
MATERIALS AND METHODS: The single-center, cross-sectional study included 50 women aged 45–59 years of reproductive stage, perimenopause, and early postmenopause. The main subpopulations of blood cells, namely, cytotoxic T lymphocytes (CD3+CD8+), T helper cells (CD3+CD4+), NK cells (CD56+CD16+), B lymphocytes (CD3–CD19+HLA–DR+), and classical (CD14++CD16–), nonclassical (CD14–CD16++), and intermediate (CD14+CD16++) monocytes and proinflammatory (CD86, CD80, CD40, and CX3CR1) and anti-inflammatory (CD163, CD206) markers on isolated monocyte populations were analyzed using flow cytometry (FACSCalibur; Becton Dickinson, USA). To detect blood plasma cytokines, a multiplex analysis method was used (Bio-Plex Human Cytokine Screening Panel; Bio-Rad Laboratories, USA).
RESULTS: In women, reproductive aging during the transition stage of reproductive aging from perimenopause to postmenopause is accompanied by increased monocyte-associated inflammatory reaction and humoral response, which is expressed in the redistribution of the monocyte population toward nonclassical monocytes (p=0.034) and increased level of B lymphocytes by 1.8 times (p=0.023) and significantly (p=0.022) increases levels of MCP-1, a marker associated with inflammation.
CONCLUSION: Immune system aging in both sexes is a natural process of ontogenesis, and in women, it correlates with the entry into the postmenopausal period. Hormonal background changes with the shutdown of ovarian function are naturally reflected in the composition of immune cells in the blood and the cytokine composition of its plasma.

The Bedretto Underground Laboratory for Geoenergies and Geosciences (BULGG) is located in south-central Switzerland in the middle of a 5.2-km-long tunnel, which connects the Bedretto valley to the Furka railway tunnel. BULGG is a multidisciplinary laboratory that facilitates experiments and research across various fields. From a seismological perspective, a dense seismic network is deployed that allows real-time monitoring of both natural and induced seismicity occurring in the tunnel and the surroundings. In addition, a multilevel monitoring approach during experiments leads to the generation of real-time high-resolution earthquake catalogs issuing event-based alerts and is the input for a simple traffic light system (magnitude and/or ground-motion based), which provides essential information for the advanced traffic-light system (probabilistic approach). We have set up two separate real-time monitoring systems that monitor the background seismicity, as well as injection experiments, with both systems built on the SeisComP framework. The background monitoring, serving as the backbone network, includes broadband sensors at the surface and along the tunnel, as well as strong-motion sensors and high-frequency geophones along the tunnel and in boreholes. The sampling rate is divergent and depends on sensor type and proximity to faults (200–2000 Hz). Acoustic emission sensors and high-frequency accelerometers sampled at 200 kHz constitute the experimental setup that locates in multiple experimental volumes, which include fluid injections, extractions, and tunneling activities. All sensors transmit real-time data to a common server (SeedLink), which serves multiple clients for processing, real-time visualization, archiving via SeisComP, and risk control via dedicated software. A standardized workflow is applied to both background and experimental monitoring, encompassing automatic picking, automatic phase association and location, and magnitude estimation. Advanced methods are implemented in real time that include double-difference relocation and earthquake detection based on waveform cross correlation. BULGG provides a unique environment to implement novel methods in observational and network seismology across scales.
Exergy Balance Applied to a Gas Turbine in a Modified Brayton Cycle to Assess the Power Output Recovery
Authors: Forero Florian Daniel Eduardo
Published: July 2024

Introduction— Gas turbines play a key role in the power generation industry. The UPME (Unidad de Planeación Minero-Energética), in its monthly report of the generation variables and the Colombian electricity market, quoted data from December 2016, highlights that the net effective capacity in megawatts is 2,093 and represents about 12.61% of the total energy capacity through gas thermal plants. During hot seasons, the performance of the turbines is affected by the elevated air temperature flowing into the cycle, because the power output depends on the air mass flow through the compressor, the mass flow decreases as the temperature increases, resulting in a decline in efficiency and power generation.
Objetivo— A gas turbine in open cycle was analyzed based on the first and second law of thermodynamics, irreversibilities were considered using exergy as the criterion to establish the overall performance of the system.
Methodology— An alternative analysis was proposed modifying the ideal Brayton cycle, humidity of the air, the height above sea level, and the detailed molar composition by component were considered. Furthermore, the heat adding process was replaced by an adiabatic and isobaric combustion progression with a subsequent cooling by means of an adiabatic mixture of ideal gases with the compressor discharged air to condition the incoming flow mixture of gases to the turbine aimed to maintain the maximum allowed temperature controlled.
Results— The simulation was developed in the software EES (Engineering Equation Solver) and the free software CEA (Chemical Equilibrium with Applications) from NASA was used to validate results for the combustion process, under the criterion of chemical equilibrium. Few investigations about inlet cooling methods for gas turbines have supported the implementation of such kind of technologies by means of exergy balance, which is the main goal of this research.

Published: July 2024

Introduction— This research is motivated, by the current world situation, caused by the pandemic declared by the WHO before the spread and severity of the coronavirus disease (COVID-19), notified for the first time in Wuhan (China) on December 31 of 2019. Through mathematical and statistical analysis, it seeks to show and explain in an expeditious manner, the causes for which there is a higher rate of contagion and lethality due to the virus, in different countries, taking into consideration patterns associated with social political behavior and economic, as a first approach to knowing statistics that allow generating forecasts for future periods, given the conditions.
Objective— The main objective of this work is to define the correlation of the economic, social and demographic variables of the countries of America, with respect to the contagion of the virus, proposing a forecast model on the level of contagion in each cluster proposed by the different regions of the American continent.
Methodology— The study performs clustering (grouping) of the countries of America with respect to their geographical position North America, Central America and the Caribbean islands and South America, followed by a search for statistical data on social, economic and demographic indicators of the countries of America in recent years and statistics of levels of contagion of COVID 19 in sources such as international organizations regulating health issues. Next, a characterization and correlation of the collected data was carried out, to finally, based on the results of the correlation, make a forecast of the level of contagion that would be reached by each of the regions.
Results— The purpose of this document is to provide information on the countries of North America, Latin America and the Caribbean with respect to the analysis of mortality from COVID-19, through methods of analysis of mortality from all causes as one of the approaches proposed to contribute to the assessment of the true magnitude of the burden of the COVID-19 epidemic in these countries.
Conclusions— The results show interesting information, since the Latin American curve turned out to be much less pronounced than that of the United States, in terms of contagion and deaths, despite the socio-demographic conditions, economic, technological and political opportunities. This analysis invites us to find out which are those correlations that directly impact the behavior of infections, taking into account variables such as age, gender, stratum, level of education, and other sociodemographic characteristics that may influence the spread or containment of the virus.
Evaluación de la contaminación por aluminio del agua para consumo humano, región central de Colombia
Authors: Ospina Zúñiga Oscar Efrén , Cardona García Oscar Hernán
Published: July 2024

Introducción: el aluminio se incorpora al agua de manera natural y/o antrópica, con niveles de riesgo para la salud por encima de 0,2 mg/L según la normativa colombiana. Puede surgir como contaminante emergente al utilizarse inadecuadamente coagulantes de sales de aluminio en la clarificación del agua potable.
Objetivo: evaluar la contaminación por aluminio del agua para consumo humano de la región central de Colombia, determinando su potencial origen y cumplimiento de la normativa vigente.
Metodología: la investigación de carácter exploratorio, analizó la presencia de aluminio en agua cruda y tratada durante el período 2007–2018, mediante muestras y ensayos de laboratorio, así como la evaluación hidráulica y de operación de plantas de tratamiento de agua, en municipios de los departamentos de Tolima y Cundinamarca, región central de Colombia.
Resultados: en más del 30% de los municipios evaluados se evidenció la presencia de aluminio en el agua para consumo humano, por encima del máximo permitido por la normativa vigente. En varios casos se debió a deficiencias en el proceso de tratamiento donde se utilizan sales de aluminio para la coagulación, sin dosificación adecuada como ocurrió en el municipio de Melgar, o por altas concentraciones presentes en las fuentes hídricas de abastecimiento, como es el caso del río Magdalena en la región central de Colombia.
Conclusiones: el aluminio en agua para consumo humano, se da por su presencia en fuentes hídricas y producto de deficiencias hidráulicas y operativas en el proceso de clarificación de las plantas de tratamiento donde se usa sulfato de aluminio como coagulante, por inadecuada aplicación de dosis óptimas, deficiente intensidad de agitación y de gradientes de velocidad en mezcla rápida y floculación, tiempos de floculación y sedimentación fuera del rango óptimo

Introduction- In recent years, the use of renewable energies and eco-friendly fuels has increased, among which one of the best performance is biodiesel, the paper shows an upgrade in the efficiency and effectiveness laboratory level's biodiesel obtaining.
Objective- Evaluating the production of biodiesel employing ultrasound is presented, leading to improve the response time and efficiency of the reaction, concerning the conventional method using only temperature.
Methodology-. In the transesterification process, castor oil, methanol, and potassium hydroxide are used, obtaining biodiesel and glycerin. A factorial design with two levels for transit time, mixing temperature, and ultrasound intensity were applied in an instrumented scale reactor to control these variables.
Results- In the tests, values close to the reference stoichiometric value of the reaction were obtained. The statistic indicates a normal behavior of data, and identifies it as a factor of incidence in the efficiency of the reaction to the intensity of the ultrasound, concerning the response time of the reaction, the mixing temperature and the intensity of ultrasound.
Conclusions- The efficiency of the reaction concerning the studied factors, it only depends on the ultrasound obtaining up to 95.7% of the stoichiometric value; and the response time of the reaction depends on the temperature and ultrasound, obtaining times of formation of product four times faster.
