Sostenibilidad del cultivo de olivo bajo un enfoque climatológico en una región árida, cabecera del desierto de Atacama
Authors: Pino Vargas Edwin Martin , Ascencios David Ricardo
Published: November 2022

La región de Tacna, Perú, caracterizada por su hiperaridez, se encuentra ubicada en la cabecera del desierto de Atacama, donde la agricultura es uno de los principales sectores económicos y el cambio climático causa grandes impactos, especialmente sobre la sostenibilidad del cultivo de olivo reflejada en la baja producción de aceituna. En este trabajo buscamos identificar la sostenibilidad del cultivo de olivo en la región de Tacna, basada en un enfoque climatológico, correlacionando la producción del cultivo con el fenómeno El Niño-Oscilación del Sur (ENOS). La sostenibilidad del cultivo está directamente relacionada con el clima, siendo la temperatura el factor principal, con amplitud de tolerancia térmica de -7 °C a 40 °C, amplitud óptima entre 15 °C y 25 °C y amplitud en la región de estudio entre 7 °C y 32 °C, lo que consideramos adecuado según los rangos establecidos, donde se obtienen rendimientos relativamente altos respecto a otras regiones del mundo. Por su lado, el fenómeno ENOS, identificado en los años de baja producción: 1980, 1983, 1992, 1998, 2009, 2015 y 2016, reportó volúmenes de producción que se reducen drásticamente. Un caso muy marcado ocurrió en el año 1998, en el cual la producción nacional (Perú) y regional (Tacna) se redujeron a 1,5 y 1,0 miles de toneladas (t), respectivamente, mientras que los valores máximos corresponden a 190,0 y 148,0 miles de t, respetivamente, para el periodo 1979-2020. Hacia el año 2025, convergen las producciones local y nacional, representando que la local sería el 100 % de la nacional.

Published: November 2022

Background

Diabetes self-management is crucial for patients with type 1 diabetes, and digital services can support their self-management and facilitate flexible follow-up. The potential of using digital patient-reported outcome (PRO) measures in routine outpatient care is not fully used owing to a lack of adapted PRO measures.

Objective

This study presents the process of identifying and adapting a digital PRO measure for use in clinical diabetes practice and describes the preferred item topics of the adapted PRO measure, as reported by patients and diabetes specialist nurses.

Methods

With the involvement of patients, diabetes specialist nurses, management, and researchers, we hosted a series of workshops and 2 dialogue conferences. Scoping searches to identify relevant PRO measures formed the foundation for the process. An in-person dialogue conference was conducted with diabetes specialist nurses as participants, and a digital dialogue conference was conducted with patients with type 1 diabetes as participants. A diabetes-specific PRO measure was translated and adapted to our digital platform. Notes and summaries from the dialogue conferences were imported into NVivo (QSR International) and thematically analyzed as a single combined data set.

Results

The thematic analysis of the 2 dialogue conferences aimed to explore the views of patients with type 1 diabetes and diabetes specialist nurses on the outcomes necessary to measure. An overarching theme, Ensuring that the PRO measure captures the patients’ needs precisely and accurately, in a way that facilitates care and communication with health care personnel, was identified and supported with data from both the patients and diabetes specialist nurses. This theme contained four categories: The need for explanatory text after questions to ensure understanding and accurate response, Capturing individual needs in standardized questions, getting to the heart of the patient’s problem, and The questions increase patient reflection.

Conclusions

We successfully conducted an iterative process that identified a PRO measure aligned with the topics raised by the diabetes specialist nurses. Similarly, the patients found the PRO measure to be relevant and one that was addressing their needs. Only minor adjustments were necessary when programming the PRO measure in the digital platform. Our management, patients, and diabetes specialist nurses had a valuable impact on the results. User involvement facilitated a specific focus on the clinical requests to be met by PRO measures and how they must be adapted to local and digital platforms. Overall, this has facilitated the current implementation of the adapted digital PRO measure.

Authors: Edwards Caitlyn , Orellana Elisa , Rawlings Kelly , Rodriguez-Pla Mirta , Venkatesan Aarathi
Published: November 2022

Background

Several barriers to diabetes treatment and care exist, particularly in underserved medical communities.

Objective

This study aimed to evaluate a novel, culturally adapted, Spanish-language mHealth diabetes program for glycemic control.

Methods

Professional Spanish translators, linguists, and providers localized the entirety of the Vida Health Diabetes Management Program into a culturally relevant Spanish-language version. The Spanish-language Vida Health Diabetes Management Program was used by 182 (n=119 women) Spanish-speaking adults with diabetes. This app-based program provided access to culturally adapted educational content on diabetes self-management, one-on-one remote counseling and coaching sessions, and on-demand in-app messaging with bilingual (Spanish and English) certified health coaches, registered dietitian nutritionists, and certified diabetes care and education specialists. Hemoglobin A1c (HbA1c) was the primary outcome measure, and a 2-tailed, paired t test was used to evaluate changes in HbA1c before and after program use. To determine the relationship between program engagement and changes in glycemic control, a cluster-robust multiple regression analysis was employed.

Results

We observed a significant decrease in HbA1c of –1.23 points between baseline (mean 9.65%, SD 1.56%) and follow-up (mean 8.42%, SD 1.44%; P<.001). Additionally, we observed a greater decrease in HbA1c among participants with high program engagement (high engagement: –1.59%, SD 1.97%; low engagement: –0.84%, SD 1.64%; P<.001).

Conclusions

This work highlights improvements in glycemic control that were clinically as well as statistically significant among Spanish-preferring adults enrolled in the Vida Health Spanish Diabetes Management Program. Greater improvements in glycemic control were observed among participants with higher program engagement. These results provide needed support for the use of digital health interventions to promote meaningful improvements in glycemic control in a medically underserved community.

La presenza della "Celestina" nelle commedie di Luigi Groto, Liquidi e Ruzante
Authors: Simonato Edoardo
Published: November 2022

L’articolo mostra come la commedia Il Tesoro (1583) di Luigi Groto, il Cieco d’Adria, rappresenti uno degli esempi più fulgidi della fortuna della Celestina nel teatro italiano del Rinascimento. Una fortuna che è stata per lo più negata dalla critica, ma di cui invece si rilevano tracce evidenti in una “linea veneta” di personaggi di ruffiane comiche che muove da Ruzante per arrivare fino a Groto, passando per il teatro della “scuola d’i Liquidi”. Proprio questi esempi veneziani di primo e medio Cinquecento guidarono il Cieco (autore pienamente inserito nel contesto teatrale veneto) verso il tardo repêchage del testo spagnolo.

Cajuput  oil  is one of the  essential oils that  widely used  as materials for  medical  or pharmaceutical products, this makes the cajuput oil become the most wanted products in essential oils industries. Cajuput oil demand is currently increasing with the growing variety of utilization of cajuput oil. Cajuput oil productions in Indonesia run into fluctuations and tend to decrease. There are several factors that affect production and quality of cajuput oil, and one of them is distillation technique. Moreover fractionation or isolation of the 1,8-cineol compound also have not been done by the cajuput oil entrepreneurs, whereas this is important in order to use 1.8 cineol compound further.Distillation of cajuput leaves is done by three distillation methods, namely water distillation, water steam distillation and steam distillation. Calculating the yield after cajuput oil obtained and then testing the physical and chemical properties of cajuput oil in accordance with the Indonesia National Standard (SNI 06-3954-2006). And then doing fractionation of cajuput oil to obtain at least 85% 1,8 Cineol compound.            The results showed that water steam distillation method produces the highest yield, the yield is  2.5%, followed by water distillation method, the yield is 1.8% and then steam distillation method, the yield is 1.5%. Physical and chemical properties that exist on cajuput oil that produced by water and steam distillation method and steam distillation method are appropriate with the Indonesia National Standard. After doing fractination processes for two time, the fractination process produced 1.8 cineol compound 79.90% in first fraction, 87.90% at second fraction and then 89.78% at third fraction.

Published: November 2022

This study deals with the effort to release new revolution of renewable energy concept. Key issue in generating hydro power from low head, low flow sources until now has been impractical, expensive in efficient and complex technology. The idea of using Hydro Coil instead of turbine gives an economic advantage that it is relatively cheaper. The apparatus allows us to exploit sides that would not be practical at all for conventional small hydroelectric power.Hydro Coil turbine in experimental prototype has been designed, built and tested. The turbine includes 4 inches acrylic with ribbon-like curved shape insert, which present a gradual curve of approximately 70 degrees from the axial flow of water progressing to a tightly curved angle perpendicular to the flow of water at the exit point. The gradual curve is used to reducing the axial velocity of water, thereby further as consequence of transfer energy from water to ribbon, thus the central axle and ribbon rotated. This rotation is initiated at the low frequency coil, with energy incrementally transferred as water, hitting the low frequency coil, turning the ribbon slowly, progressing gradually to higher frequency, tight coil where maximal energy to the transfer occurs.Characteristics and efficiency of Hydro Coil turbine can be identified after laboratory experimental already finished. Turbine efficiency in 92.93% of this prototype exceeds expectation in the experiments. It thus demonstrates the promising potential of Hydro Coil technology to extract power from incoming water flow in low head sources.

Authors: Fajarsari Aspita Dyah , Sulaiman Muhammad , Setiawan Bakti
Published: November 2022

Yogyakarta Province until 2014 has built a total of 10 (ten) micro hydropower plants (MHP). However, from these ten MHPs, there is only 1 (one) which is still in operation, namely Kedungrong MHP. This Kedungrong MHP was selected as the research area due to its success in managing the MHP so that the electricity generated can be used by its local residents until now. Based on this best practice, the other MHPs which are still under construction or that have ‘stalled’ should learn from Kedungrong MHP to be able to reoperate so that they will be sustainable.This research employed mixed methods, between the quantitative research method and the qualitative research method. First, the data were collected using surveys, interviews and observation and then the model of the management system that Kedungrong MHP applies was described and evaluated.The findings of the research suggest that a sustainable MHP integrates three aspects, namely technical and environmental, social as well as economic aspects. The technical aspects deals with civil, mechanical and electrical components at the stages of planning, developing to operation and maintenance. The social aspects look carefully at community participation at the stages of planning, developing to operation and maintenance. Finally, the economic aspects pay attention to sources and forms of financing at the investment stage, the operation stage and the maintenance stage. In relation to the MHP scale, of those three aspects, the one that has the most significant impact on the sustainability of the MHP is the social aspects.

Published: November 2022

The business world has experienced a paradigm shift towards a more modern concept. Many business processes are carried out through the internet or commonly known as e-commerce, by utilizing a platform known as Marketplace. One of the marketplaces that are quite well-known and in great demand in Indonesia is Shopee. The high online shopping activity in the current marketplace indirectly encourages business actors to understand the online market. However, one of the obstacles that are quite often faced by sellers, especially new sellers who are starting to enter the digital realm, is the emergence of confusion in the selection of products to be sold due to a lack of information regarding the demand for what products are in demand in the market.The process of searching for information related to the demand for products of interest is carried out through clustering analysis to find out the groups of products that are of interest to those that are less attractive to the public. The data used is product data from 6 categories in the Shopee market which was taken using web scraping techniques. The clustering processes used the K-means approach by determining the number of K and the optimal center point through the calculation of Sum Square Error (SSE) by looking at the elbow graph. The final results show the optimal number of K clusters that are different in each category, namely in category women’s clothing, men’s clothing, and electronics are at K=4 then for products in the category of Muslim fashion, care & beauty and household appliances are at K=3. Based on the validation results using the Davies Bouldin Index, values were obtained in6 categories, namely 0.391, 0.438, 0.414, 0.357, 0.387, and 0.377, which means that the cluster structure and the level of information formed in each category using the K-Means method is quite good.

Authors: Aprieza Feikal , Ridwan Mohammad Kholid , Wilopo Wahyu
Published: November 2022

The COVID-19 pandemic as a global pandemic on 2020 has encouraged the Indonesian Government to establish pandemic response policies in many provinces. The policies that had been restricting mobility during the pandemic showed significant impacts in many aspects in the Special Region of Yogyakarta. A shifting pattern in electricity consumption can be seen as the growth of economic sectors in the GDP encountered contraction after the decline of community mobility. Electricity demand forecasting is required to analyze the impact of the COVID-19 pandemic by applying three scenarios, specifically an unlikely pandemic scenario or Business As Usual (BAU), moderate scenario (MOD), and optimistic scenario (OPT). Also, the household, industrial, business, social, and public sectors are analyzed in order to see the shifting pattern in electricity consumption through the scenarios that have been given. Energy modeling is conducted with Low Emission Analysis Platform (LEAP) software to analyze electricity demand forecasting from 2019 to 2030 based on the three scenarios. The results show that the electricity demand in 2030, according to BAU, MOD, and OPT scenarios, in the amount of 5,301.58 GWh, 4,489.11 GWh, and 4,648.12 GWh, respectively. According to the MOD and OPT scenarios, the electricity demands of the household and industrial sectors will increase relative to the BAU scenario. Meanwhile, according to both scenarios, the electricity demands of the business and social sectors will decrease. In the public sector, the MOD scenario shows the decline of electricity demand relative to the BAU scenario, while OPT scenario shows the opposite.

Lockdown is one way to reduce the transmission rate of COVID-19. Nevertheless, on the other hand, lockdowns also increase human psychological problems to cause the emergence of emotional eating. In addition, social media exposure that presents food photos can trigger the desire to eat. However, this only applies to high-fat and high-calorie foods, while healthy foods do not have the same stimuli. Therefore, more research is needed on the properties of healthy food photos desired by consumers in order to be able to create or design healthy food photos with an effect that resembles photos of high-fat and high-calorie foods. This study employed the Kansei Engineering approach in designing healthy food photos. Through Kansei Engineering, we can determine the nature of healthy food photos consumers want. The type of Kansei engineering used in this study was Kansei Engineering Type I and was limited to the Semantic Space stage. The process of factor reduction from the results of the semantic differential was carried out by using factor analysis to obtain the most critical factors related to healthy food photos. The semantic space spanning resulted in 23 pairs of Kansei words that related and represented healthy food photos. Based on the factor analysis results, these Kansei words were then into 6-factor groups. Each of the factor groups was represented by the Kansei word pair with the highest loadings value. The selected pair of Kansei words showed that healthy food photos could be represented by Kansei words attractive, contrast, proper lighting, neat, high-quality image, and straightforward.

Published: November 2022

Mass media plays an important role in our lives and society to a greater degree. As a primary source of information that people tend to go for, the kind of information mass media provides matters. The problem is that every message we see in the media is constructed and that even texts like news reports are not entirely authentic. Previous studies have shown that news media do have their own tendency in writing their news reports, through which the minority communities are usually the ones to receive the short end of the stick. On that account, this study, through conducting critical discourse analysis, attempts to see the media framing in Mauree Turner’s 2020 Oklahoma state legislative election news reports and find an underlying motive behind such framing. The finding shows that in general, the media framed Turner positively in their reports and that this positive frame implies an inherent gender bias and religious discrimination within American society.

Published: November 2022

Objectives This study aims to understand preservice kindergarten teachers’ belief systems on teaching and their recognized meaning of teaching so that they can redefine their own perceptions of teaching. Methods To this end, this study selected 90 consistently participatory students out of a total of 102 students enrolled in the childhood education program’s third term early childhood teacher education course at a 4-year college of education in the S district of Jilin province, China, and collected data through multiple methods including conducting discussions, image analysis, and kindergarten class video analysis. Results The study’s results showed that Chinese preservice kindergarten teachers’ understanding of the meaning of teaching can be broadly categorized into: two-way interaction, social responsibility and duty, problem-solving situations in daily life and directly related activities, and optimistic and harmonious emotional development and related activities. Conclusions The findings show that first, teaching is not merely a means to an end but an act pursuing goodwill in and of itself, is a practical execution that goes beyond being a tool, and is a “relative” practical execution that requires the responsibility of having the ability to react. Second, as an act that tells the learner the direction they should go in and passes on an understanding of the directionality learners ought to make judgments with, teaching is an act that requires responsibility and a sense of duty. Thus, the meaning of teaching to a teacher must expand and teachers must develop the ability to independently recognize and judge the way they teach. Third, as the act of teaching is related to problem-solving in daily life, practical knowledge must be emphasized and developed. Fourth, since the act of teaching is related to optimistic and harmonious emotional development, the perception of teaching and a positive job identity are very important. The conclusion of this study suggests that recognizing teaching morality before executing the teaching role at the preservice kindergarten teacher stage and making philosophical reflections about teaching are necessary.
