La depresión como relacionalidad científico-cultural
Authors:   , Huerta Muñoz Laura
Published: April 2024

La presente investigación se enfoca en el estudio de la relacionalidad ciencia-cultura para la conceptualización de la depresión como categoría psicológica, a través del análisis documental y su comparación con narrativas recogidas en entrevistas. Las conclusiones de la investigación son: 1) cultura y teoría se influyen mutuamente para concebir la depresión y la normalidad; 2) el estudio de la depresión obedece a una demanda social tanto como a la búsqueda de prestigio dentro del campo científico, mientras la intervención clínica satisface una demanda social; 3) que la heteronomía del campo psi se vincula con intereses no sólo económicos sino también políticos y culturales; 4) que en los últimos cincuenta años el estudio de la depresión en términos de su etiología se ha centrado en aspectos neurológicos pese a que no exista evidencia suficiente que sostenga tales hipótesis; 5) que no existe una “verdad” unívoca sobre lo que es la depresión, sus causas y desarrollo; 6) que la comprensión actual de la depresión gira en torno a presupuestos morales sobre cómo las personas deberían funcionar en la vida social; y, 7) que la percepción del malestar y el bienestar está enmarcada por la definición colectiva que se hace sobre ellos. A partir de los resultados de la investigación, se propone que: 1) el concepto “depresión” (forma objetivada de representaciones sociales) supone un objeto que permite narrar la experiencia personal, al mismo tiempo que como objeto de estudio científico permite enmarcar la experiencia según una serie de definiciones y prescripciones. Es a la vez estructurado y estructurante, por lo que se vuelve objeto institucionalizado para la ciencia y objeto incorporado (encarnado) para la comprensión de los estados internos y comportamientos individuales; y, 2) que existen ajustes estructurales en función de los cambios en la posición del agente, a la vez que las decisiones y cambios en la vida práctica de las personas afectan sus posiciones en la estructura, provocando desplazamientos tanto del agente como de otros agentes, lo cual conlleva a una constante relacionalidad (ajustes entre los agentes y la estructura) que llevan a conceptualizar e intervenir sobre la depresión.

Published: April 2024

The present study deliberates the recovery of sodium fluoride (NaF)-natrite (Na2CO3)-sodium chloride (NaCl) ternary fluxing agent from hazardous aluminum dross waste using three types of heating methods, including direct heating on a hotplate, heating by a drying oven, and microwave heating. Deionized water was used as a green solvent for the recovery experiments. Investigating the effects of time and temperature on recovery percentage showed that a recovery percentage of around 96.5% can be achieved under time and temperature of 90 min and 95 ℃, respectively. The recovered fluxing agent salt was characterized by XRD, FTIR spectroscopy, FESEM, and energy dispersive X-ray spectroscopy (EDS) elemental analysis. Rietveld fitting analysis of phases detected in the XRD patterns showed that the recovered fluxing agent contained 74–81 wt.% NaF, 8–11 wt.% NaCl, and 11–14.7 wt.% Na2CO3. The FESEM micrographs revealed that the retrieved salts were in nano scale. The recovered fluxing agent showed different morphologies including needle-like, round shape, and a mixture of both, corresponding to microwave, drying oven, and hotplate heating methods, respectively. The nano-needles exhibited diameter of the tip and base in the range of 39–60 nm and 50–103 nm, respectively.

Published: April 2024

Recognizing pneumonia sufferers can be done by analyzing chest X-ray images. Pneumonia sufferers experience pleural effusion, where fluid is between the lungs’ layers. It causes the lungs’ X-ray picture to be cloudy or hazy. It differs from the appearance of X-rays on normal lungs which are dark in color. These differences in X-Ray images can be classified automatically with the help of Artificial Intelligence This research used convolutional neural networks and support vector machine methods to recognize X-ray images of pneumonia. This research applied Principal Component Analysis and Wavelet Transformation support to both methods. This research aimed to evaluate the performance of each model combination. The PCA-SVM model gave the best performance, with an accuracy of 94.545% and an F1 score of 94.675%. The SVM model outperforms the CNN model in recognizing images; in this case, it could be due to the relatively small amount of training data.
Quickly Assess the Acceptability Sentiment of White Paracetamol Intake Using KNN-SMOTE Based On Receptive Deciding
Authors: Malik Rio Andika , Riza Faizal , Defit Sarjon
Published: April 2024

This research aims to develop a fast and adaptive sentiment evaluation approach related to the use of white paracetamol using a combination of the K-Nearest Neighbors (KNN) algorithm, Synthetic Minority Over-Sampling Technique (SMOTE), and the Receptive Deciding concept. Imbalances in the dataset, where positive sentiment may predominate, are addressed through the use of SMOTE to synthesize minority class samples. The KNN algorithm is applied to build a sentiment classification model, while Receptive Deciding is used to provide adaptive intelligence to changes in sentiment. The SMOTE oversampling process is carried out to achieve class balance, while KNN is used to classify sentiment. Receptive Deciding is applied to increase the model's adaptability to changes in sentiment. The research results show that the integration of the SMOTE, KNN, and Receptive Deciding methods provides an effective approach in assessing sentiment accurately and adaptively. The developed model is able to recognize changes in sentiment over time and provide balanced evaluation results. These findings are expected to contribute to understanding public sentiment towards the use of white paracetamol, as well as being the basis for developing more effective health communication strategies.

Multiverse atau Multisemesta, jagat raya majemuk, atau multiversum merupakan hipotesis berupa kemungkinan adanya beberapa alam semesta termasuk alam semesta yang kita tempati. Alam semesta ini terdiri dari segala sesuatu yang ada yakni: keseluruhan ruang dan waktu, materi, energi serta hukum fisika didalamnya. Secara filosofis, di alam semesta tidak pernah ada sesuatu hanya satu. Planet Bumi bukan satu-satunya planet yang istimewa, karena faktanya kita punya tujuh planet lainnya. Matahari juga mungkin hanya satu dari banyak bintang di galaksi yang ada di alam semesta. Sehingga tentu bukan hal yang tidak mungkin jika ada lebih dari satu alam semesta yang mungkin tidak terhitung jumlahnya. Tujuan penulisan arikel ini adalah memberikan gambaran bagaimana konsep multiverse, mulai dari sejarah perkembangan tentang Multiverse terjadi hingga pro dan kontra yang menyertainya menurut pandangan filsafat dan sains. Metode penulisan dalam artikel ini menggunakan pemaparan kualitatif yang bersumber dari kajian literatur (literature review) dari berbagai sumber yang relevan. Hasil kajian menunjukkan bahwa sepanjang sejarah perkembangan konsep multiverse menuai pro dan kontra yang belum terselesaikan hingga kini.

In the midst of the pandemic Covid-19, many Indonesians have opened E- Commerce to fullfill their daily needs because they have been affected by this Covid-19 pandemic. This program is one of the forms of E-Commerce that was created during the Covid-19 pandemic, starting from December 2020 which was named Maniak Mainan at Indonesian E-Commerce, Tokopedia. Currently the products listed on Tokopedia Maniak Mainan is around 6100 products, therefore a recommendation program is made to provide users with suitable choices according to the price chosen through the bottom of the product page. This program also has a customer loyalty feature that allows users to get discounted prices by adding the nominal amount of purchases on the Maniak Mainan website. The recommendations and customer loyalty made using the K-Means Clustering method obtained using original sales and product data from Tokopedia Maniak Mainan. However, this cluster center will adjusted when the admin uploads a product with a higher or lower price, and the customer loyalty tier will also change if the user's purchase nominal exceeds the previous highest nominal. Through the results of the test, it can be concluded that 20 cluster centers are the right distance for this because it includes the price of products that are nearby. The compatibility test was carried out with the Silhouette Score with the results of 0.579 on the recommendation and 0.689 on the customer tier

Communication is a habitual thing for every human, whetherit's communicating directly orindirectly. When a natural

disaster happens, problems can occur on communication systems. These problems can lead to information being not

received properly, so the two parties communicating didn’t know the content of the message. In this situation,

a two-way radio device is the best solution that can be used to communicate. A two-way radio device enables the user

to communicate without any cellular network or internet, because the radio can be both a transceiver or a receiver

in its own frequency. A common two-way radio device uses UHF frequency range (400 MHz - 520 MHz) because

of the characteristics of this frequency range that can penetrate buildings or vegetation that usually interfere with the

radio signal. However, a two-way radio device has a broadcast and unencrypted characteristic, so that every

conversation that is happening between the radio users can be heard by other users. In an emergency situation such

as a natural disaster, important and confidential information shouldn’t be heard by an unauthorized person. So in

this project, the writers have a goal to design an encrypted text based communication system that works on the UHF

frequency band.

Abstract. We investigate the impact of the percentage of clean water access, the percentage of handwashing habit, and the toilet category factors on the upper quantile of toddlers’ diarrhea risks in Bandung city, Indonesia using Geographically Weighted Quantile Regression model. We analyzed  districts in Bandung, applying Geographically Weighted Quantile Regression with the predictors are the percentage of clean water access, hand washing habit, and toilet category. We focus on the 75th percentile ( . Breusch-Pagan test was used to detect the spatial heterogeneity. The optimum bandwidth was selected using cross-validation. The results shows that the significance, strength, and direction of the relationship between diarrhea and its risk factors are found to depend on the location. At the upper quantile τ = 0.75, the district named Panyileukan district is predicted to have the highest diarrhea risk. In this district, all of the three predictors are significantly affecting the toddlers’ diarrhea risk with the variable of percentage of houses practicing hand washing habit is observed to reduce diarrhea risk the most. In conclusion, clean water access, handwashing habits, and toilet category are the potential risk factors of high-risk childhood diarrhea. The significance, strength, and direction of the effect varies between districts. This method is powerful as it would allow the decision maker to handle the diarrhea problem aptly based

Published: April 2024

Abstract. Various daylight simulation tools, which are rapidly developed, become a reliable way for simulating the complex daylighting environment. Empirical validation of the daylight simulation tool is essential in determining its reliability, especially in simulating light transport and shading system in the Tropics. Distinct from previous research, the validation involves Horizontal Light Pipe (HLP), a side window with shading systems in different room aspect ratios and orientations. This study aims to validate the simulation results of Integrated Environmental Solutions-Virtual Environment (IES-VE) Radiance IES with the measurement results of physical scaled models for evaluating HLP, light shelves, and blinds' daylight performance under intermediate and overcast sky conditions. Two physical scaled models 1:10 represent office rooms with HLP and shading systems with different room aspect ratios were constructed. Daylight Factor (DF) and Daylight Ratio (DF) of physical scaled model measurement and IES-VE simulation were compared. The results showed that under intermediate and overcast sky conditions, the Pearson correlation between simulation and measurement results using DR and DF was strong, significant, and positive, as high as 0.84 and 0.80, respectively. The Mean Bias Error between simulation and measurement results under intermediate and overcast sky conditions were -12% and -7.7%, respectively. IES-VE is reliable to evaluate the HLP and shading systems' daylight performance with different room orientations in the Tropics.
Surfactant Flooding Performance Between Carbonate Reservoir and Sandstone Reservoir
Authors: Setiati Rini , Jasmine Gabriella
Published: April 2024

Abstract. High energy consumption must be balanced with an increase in oil reserves. One of them is to increase reserves from existing fields. So far, abundant oil production is still sourced from old or brownfields. This makes many oil companies still make efforts to increase their production on the brownfields. One of these efforts is implementing Enhanced Oil Recovery (EOR), intending to maximize recovery (RF) from the oil field. Enhanced Oil Recovery (EOR) can be categorized as a tertiary production stage to obtain oil in various types of reservoirs, especially heavy oil reservoirs. Around 60% of the world's oil reserves are in carbonate reservoirs, and the rest is sandstone and other lithologies. Therefore, it is crucial to know the characteristics of the reservoir to support the success of the EOR carried out. The stages of tertiary oil production are mainly carried out by chemical means. One widely used method in the field is surfactant injection or surfactant flooding. Surfactant flooding is an EOR method by injecting a surfactant-brine solution into a reservoir filled with oil that the previous step cannot wash away. Of course, surfactant injection carried out in both types of reservoirs will give different results considering the characteristics of each rock. The parameters examined were surfactant adsorption ability by both rocks, alteration of wettability after surfactant was injected, and recovery factor after injection. It was found that the surfactant adsorption on sandstone was low compared to carbonate rock; the wettability alteration was also more effective on sandstone compared to carbonate rock. So that from these two parameters, a higher recovery factor value is obtained in sandstone than carbonate rock reservoir.
