Authors: Aulia Rina , Adhilla Fitroh , Yusoff Rushami Zien
Published: December 2024

Purpose- Technology is one of the most essential things in human life. The advancement and development of technology, especially communication technology, cause every telecommunications company to continue improving its products' excellence to keep up with technological developments. This study aims to determine the effect of price, product quality, and brand image on consumer satisfaction of iPhone Smartphone users in Yogyakarta, Indonesia.
Design/Methodology/Approach- The study subjects were people in Yogyakarta, Indonesia, with a sample size of 100 people selected using a purposive sampling technique. This research uses a quantitative approach and data collection techniques, such as distributing questionnaires. Instrument tests were carried out with measurement models, validity tests, reliability tests, and structural model testing through bootstrapping. The analytical tool used in this research was Smart PLS 3.0.
Findings- The study's findings show that consumer satisfaction is positively impacted by price, product quality, and brand image. Customers are satisfied when the price is determined according to the demands or advantages they want. Customer satisfaction will be determined by the product's quality. Furthermore, the brand image will give an impression of a product. When using or buying a product, consumers will choose products with a familiar brand image because it will give the assumption that a positive brand image will provide consumers with a feeling of satisfaction.
Research limitations/implications- The limitation of this research is the process of collecting data from respondents, which takes quite a long time. The distribution of online questionnaires was only addressed to respondents who used iPhone Smartphones in Yogyakarta, so the respondents' answers could not represent all Smartphone users of various brands in Yogyakarta, Indonesia.
Originality/value- There is still little research on the antecedents that cause consumers to use iPhone smartphones, especially in Yogyakarta. Similar studies only discuss Smartphone users in general in Yogyakarta or iPhone Smartphone users in several regions in Indonesia.

Authors: Abidin Zainal
Published: December 2024

Purpose-Advances in digital technology impact various business activities, such as digital marketing through e-commerce. Digital marketing through e-commerce can expand consumer reach while reducing business operating costs. In digital marketing, each seller will try to attract consumers to buy their products. Many factors certainly influence consumer intention to buy. Therefore, this study aims to determine the effect of perceived usefulness, perceived ease of use, and lifestyle on purchasing intentions in e-commerce users.
Design/Methodology/Approach-This study's population consisted of all e-commerce users in Asia, and the sample obtained was 100 people selected based on specific criteria. The data was collected by distributing questionnaires online and measuring them using a Likert scale. The data obtained from respondents was then processed using SPSS software.
Findings-Based on the test results, perceived usefulness, perceived ease of use, and lifestyle positively affect the purchase intention of e-commerce users. The perceived usefulness of this study has proven to be positive but insignificant to consumer purchase intentions. This means that perceived usefulness only partially encourages consumer buying intentions because other factors highly influence buying intentions, such as perceived ease of use, lifestyle, and other factors not examined in this study.
Research limitations/implications-This research is limited in that the respondents' sample only represents e-commerce users in Asia, so the respondents' answers cannot represent all e-commerce users worldwide. In addition, e-commerce currently circulating is diverse, and this research has not discussed specific e-commerce users, so future research is expected to use specific e-commerce user respondents.
Originality/value-Research on the factors that influence purchase intention through e-commerce in Asia still needs to be improved. This research discusses e-commerce users in the Asian region by considering the aspects of perceived usefulness, perceived ease of use, and lifestyle.

Use of bitter melon seed oil (Momordica Charantia) to Improve the photoprotective effect of Sunscreen Formulations
Authors: Winarti Lina , Refayani Ema Prastiwi
Published: December 2024

Bitter melon seed oil (BMSO) was identified as having potential as an anti-UV radiation agent due to alpha-oleo stearic acid, flavonoids, tannins, polyphenols, and phytosterols, which have the potential as antioxidants. Antioxidants are the main protection for the skin from the dangers of solar radiation, making BMSO a good quality if developed in sunscreen cream. This research aims to determine the effect of adding variations in the concentration of BMSO on the physical characteristics and in vitro photoprotective effectiveness of cream of oxybenzone and octyl methoxycinnamate. Sunscreen creams are made with each BMSO concentration of 0%, 6%, 8%, 10%, and 12%. The result shows that the greater the concentration of BMSO added, the lower the viscosity and pH values, the spreadability and SPF (sun protection factor) values of the cream increase, and the %TP (percentage of transmission pigmentation) and %TE (percentage of transmission erythema) become smaller. The best formula is the formula that contains the highest concentration of BMSO (12%). The characteristics of the best formula are a slightly yellowish, soft cream appearance and a slight smell typical of bitter melon. The spreadability value of the best formula cream is 6.6 ± 0.1 cm, pH of 6.57 ± 0.01, and viscosity of 88.3 ± 4.1 dPa.s, SPF value of 24.27 ± 0.28, %TE of 0.931 ±0.084, and %TP of 0.981±0.0001. These results show that BMSO has the potential to be an active ingredient in sunscreen to reduce the negative effects of using synthetic sunscreen, such as allergenic and irritant.
The redox titration of Fe (II) ions with K2Cr2O7 using a potentiometry method the effect of EDTA and SCN- ligands
Authors: Herlina Herlina , Razali Muhammad
Published: December 2024

Complexometric titration is often used for determining the metal content, either through direct titration or back titration. This study aimed to investigate redox titration between Mohr salt solutions and potassium dichromate in an acidic atmosphere in the pH range 2. The results showed that the reaction proceeded effectively at pH 2, with Mohr's salt solution acting as titrant. Furthermore, experiments were conducted to compare the effectiveness of EDTA ligands and SCN- ligands in improving the sharpness of the Fe2+/ Cr2O72- redox titration curve at pH 2. Results show that EDTA ligands are more effective than SCN- ligands in improving the sharpness of the titration curve. However, it should be noted that the addition of EDTA ligands can shift the equivalent point volume earlier, so adjustments need to be made in redox titration analysis. Research has also shown that adding excess moles of EDTA to total Fe (II) ions can decrease redox potential in Fe2+/ Cr2O72- systems. These results provide additional insight into the use of EDTA ligands in redox titration analysis and their relevance to redox potential changes in the systems studied.

Authors: Prasetya Rahmad Aji , Arifiyana Djamilah , Syulthoni Zain Budi
Published: December 2024

Despite low nicotine levels, cigarettes and vape liquids can cause addiction, which makes quitting smoking difficult owing to withdrawal syndrome. Hence, we created a nicotine-free liquid vape using essential oils (EOs) like peppermint (Mentha piperita), lavender (Lavandula latifolia), and tangerine (Citrus reticulata) to substitute the nicotine in inducing relaxation without addiction. Thus, this study aimed to examine (1) the safety profile of this nicotine-free liquid vape by observing chemical characteristics using gas chromatography-mass spectrometry (GC-MS) and (2) its efficacy in reducing short-term anxiety in healthy volunteers who had previously used nicotine vape. The most complicated vape liquid formula (F4), containing propylene glycol, vegetable glycerin, with those three EOs, was injected into GC-MS, and the mass spectra were compared to the Wiley mass spectral library to identify the compound name. For the efficacy test, subjects who met inclusion criteria and fulfilled informed consent were randomly assigned to five groups (four groups received test liquids formula (F1-F4) while one group received placebo). Before and after using the vape liquid, subjects were asked to complete the State-Trait Anxiety Inventory (STAI) questionnaire to assess its anxiety-reduction effects. The result showed that nicotine-free vape liquids containing three EOs did not show any foreign substances that had never been encountered before, which means our product is safer than nicotine-containing vape liquids. This safety was also supported by all study subjects who did not report any adverse effects. The efficacy test showed that subjects who used vape liquids with essential oils (F1-F4) experienced a significant decrease in heart rate and systolic blood pressure. At the same time, 50% had a lower post-test STAI score, indicating a decrease in anxiety, although it was not statistically significant.
Cost Optimization for Logistics Services: A Simulation Approach to Delivery Alternatives
Authors: Sihotang Farida
Published: December 2024

An essential activity in the delivery of goods by logistics service companies is how to deliver goods to consumers according to the agreed time with minimal costs. A case study was conducted on one of the logistics service companies in Bandung, which has an exciting feature: promising goods to consumers within 24 hours. The interesting thing about this company is that it uses the rest of the luggage of travelers traveling to the destination city by plane. In existing conditions, problems often arise, namely, goods do not reach customers according to the agreed time. This causes losses to the company because it must pay a late penalty. Therefore, the author designed several alternatives to meet freight forwarding in less than 24 hours. This study aims to optimize the cost of shipping goods from various alternatives by considering the delivery time of less than 24 hours. This study uses an experimental method with a system model to conduct simulations. Parameters use primary data from the company and secondary data from websites. The author designed two alternatives to shipping goods if no match was found with the traveler. The first alternative is to use air cargo at Bandung Airport. The second alternative is that if it is predicted that the goods will not reach the customer within 24 hours through Bandung Airport, they will be sent to Soekarno Hatta Airport Jakarta using a truck. A match with the traveler at the airport will be sought. The second alternative is also considered if there is no match with the traveler, then the delivery of goods uses air cargo. The simulation results provide a total cost for alternatives 1 and 2 of IDR 69,779,084.40/month and IDR 107,025,296, respectively, for goods that do not meet the delivery of less than 24 hours for alternative 1, namely nine items/month or 1% of the total shipment and alternative 2, namely 19 goods or 2% of the total delivery. The simulation in this study resulted in choosing the first alternative as the best alternative with the lowest cost.

This sector processes agricultural products through various methods, adding value and yielding higher profits than raw commodities. Corn, a staple in Indonesian agriculture, is predominantly cultivated with limited post-harvest activities, impeding rural economic growth. This study examines the supply chain management of the corn agro-industry to enhance value addition and competitiveness. Utilizing the Hayami method, the research identifies stages in the corn processing chain, including cleaning, grinding, filtering, and drying, and evaluates the value added at each stage. The analysis reveals that the supply chain involves multiple stakeholders, from farmers to retailers, and highlights the disparity in value addition among different actors. The study concludes that effective supply chain management, risk mitigation, and strategic interventions are vital for sustaining the corn agro-industry. Recommendations include extended mentorship for farmers and the implementation of efficient production practices to ensure long-term sustainability and economic growth.
Sentiment Analysis and Emotional Language as Predictors of Drug Satisfaction in User Reviews
Authors: Lumintu Ida
Published: December 2024

This study investigates how emotional expressions in user-generated drug reviews predict satisfaction ratings using sentiment analysis and emotion detection. By analyzing over 370,000 reviews from the UCI Machine Learning Repository, the study aims to bridge gaps in understanding the emotional drivers behind user satisfaction across different drug categories. For sentiment analysis, VADER, a Python-based lexicon tool, was used to categorize sentiment polarity, while the NRC Word-Emotion Lexicon provided a nuanced mapping of emotions like joy, sadness, and anger. Results reveal that emotions such as joy and trust are positively correlated with higher ratings, while anger and disgust are linked to lower satisfaction. However, the R-squared value (~0.043) indicates that emotions alone do not fully predict ratings, highlighting the need to consider additional factors like drug efficacy and side effects. This low R-squared value suggests that while emotions significantly influence satisfaction, other elements play a substantial role. The study's findings have critical implications for pharmaceutical companies and healthcare providers, suggesting the need for emotion-driven marketing strategies and improved patient support systems. Future research could explore more advanced machine learning models, such as BERT or GPT-based approaches, and investigate specific user demographics or drug side effects to enhance predictive accuracy.

Published: December 2024

Lung cancer remains the leading cause of cancer-related deaths worldwide. Pulmonary nodules, indicative of tumor growth, present significant diagnostic challenges due to their varying sizes and shapes. Computed Tomography (CT) is commonly used for lung cancer screening due to its high sensitivity and efficacy in detecting these nodules. However, differentiating between benign and malignant nodules can be difficult due to their overlapping characteristics. To address this challenge, we propose a Rebuild Convolution Block Attention Module-based Convolutional Neural Network (RCBAM-CNN) designed to accurately classify lung nodules from CT scans. The RCBAM-CNN integrates a Rebuild Convolution Block Attention Module (RCBAM), which includes reshaped layers and redefined spatial attention mechanisms to enhance the network’s focus on relevant features while minimizing noise. The performance of the proposed method is evaluated using the LIDC-IDRI dataset. Data augmentation techniques, including rotation, rescaling, and both vertical and horizontal flips, are applied to improve the model’s robustness and generalization. Subsequently, U-Net is employed for precise image segmentation, ensuring accurate delineation of nodule regions. The proposed RCBAM-CNN demonstrates exceptional performance, achieving an accuracy of 99.72%, surpassing existing methods such as adaptive morphology with a Gabor Filter (GF) and Capsule Network-based CNN. This approach represents a significant advancement in lung nodule classification, offering improved diagnostic accuracy and reliability.

Nowadays, online reviews wield considerable influence over consumer decision-making processes. Surveys show 84% of people compare their trustworthiness to recommendations from personal connections in these online reviews. Online reviews of services or destinations can significantly benefit the tourism industry. Therefore, our primary intent of this study is to leverage Machine Learning (ML) and Natural Language Processing (NLP) for sentiment analysis of hotel reviews in Jordan in order to assist both hotel owners and tourists. In this study, we proposed a ML-based approach using Support Vector Machine (SVM) and TF-IDF to perform sentiment analysis of hotel reviews into positive or negative. In addition, our experiments were performed using our real dataset, “JOHotelRating”, which was gathered in the Jordanian context. In the feature extraction stage, we utilized the Term Frequency-Inverse Document Frequency (TF-IDF) method. In the machine learning (ML) classification phase, we utilized various algorithms such as Support Vector Machine (SVM), Multinomial Naïve Bayes (MNB), Bernoulli’s Naïve Bayes (BNB), Decision Tree (DT), and Random Forest (RF). SVM with TF-IDF for feature extraction, emerged as the standout performer, achieving an impressive 97% accuracy in sentiment classification. Our proposed approach offers the hotel owners a time-saving method to identify positive and negative reviews, allow them to understand trends, and enhance the overall customer experience. On the tourist side, the study attempts to tackle the challenge of comprehending numerous reviews by providing sentiment analysis, ultimately aiding them in making better-informed decisions when selecting a hotel in Jordan.

UAVs have become key in various applications lately, from catastrophe relief to environmental monitoring. The plan of powerful and reliable directing protocols in UAV networks is seriously hampered by the dynamic and habitually eccentric mobility patterns of UAVs. This study proposes a novel technique to beat these challenges by utilizing the Modified Smell Bees Optimization (MSBO) algorithm to upgrade the weights of CNNs. This study’s principal objective is to further develop UAV network routing decisions by using CNNs’ ability for design recognition and the Modified SBO’s optimization abilities. Our methodology comprises of randomly relegating CNN weights to a populace of bees at start, evaluating their wellness by fitness of directing performance, and iteratively fine-tuning these weights utilizing local and global search procedures got from bee searching. Broad simulations and performance evaluations show that our recommended approach incredibly expands the general dependability of UAV’s, brings down communication latency, and improves directing productivity. Future exploration in UAV network improvement gives off an impression of being going in a promising direction with the integration of CNNs for pattern recognition and the Modified SBO for weight enhancement. In addition to progressing UAV routing conventions, this work sets out new open doors for machine learning applications of bio-inspired optimization algorithms.

PERFUSION INDEX VALUES ARE CONSISTENT ACROSS COMMON LYING SURGICAL POSITIONS
Authors: Perez Etxeberria-Arteun Mikel , Walzel Simon
Published: December 2024

Perfusion Index (PI) is an important vital sign in medical practice, with increasing utility in a variety of medical specialties. Its relevance extends to critical care and serves as a valuable measure of anesthetic efficacy. Despite its growing importance, there is a notable lack of literature on the potential impact of different surgical positions on PI measurements. Therefore, this study attempts to fill this gap by investigating whether PI exhibits variance in four different surgical positions: supine, prone, right and left lateral decubitus. The interventional prospective study included 27 volunteers who underwent PI measurement in each position in a randomized order. Using a one-way analysis of variance (ANOVA) for repeated measures, the results showed that at a 5% significance level, no significant differences were found in measured PI values between supine, prone, right and left lateral decubitus positions. Higher standard deviations in the right (±4.46%) and left (±4.58%) lateral decubitus positions indicate greater PI variability than in the supine (±3.91%) and prone (±3.88%) positions. The results suggest consistency of PI measurements across different surgical positions, adding to the knowledge of standardization of PI measurements and interpretation of measured absolute PI values.

Published: December 2024

Uma tensão existente entre biologia e cultura no desenvolvimento humano foi o mote que perpassou psicologia e educação. No começo do século XX essa discussão se fazia presente de forma acentuada nos manuais de formação de professores. Este artigo tem por objetivo fazer uma análise do tensionamento entre biologia e cultura na educação brasileira por meio da análise documental de manuais de formação de professores utilizados nas primeiras quatro décadas do século XX. A análise histórica cumpre não só o objetivo de resgatar a memória e descrever o contexto e o espírito de um tempo, mas também permite ver as implicações de uma época para os fatos que se desenrolaram. Amplamente baseada em aspectos biológicos e higienistas a educação brasileira deu seus primeiros passos rumo à cientificidade. O debate em educação de forma alguma pode estar distanciado das demandas econômicas, políticas e culturais de uma época.

Authors: Quatrochi Gabriel , De Souza Cinthia , Ferreira de Araújo Renan
Published: December 2024

The article aims to show how financialization intensifies the subordination of peripheral economies in relation to the central ones, focusing on Brazil. Financialization is defined as a systemic pattern of wealth, driven by financial liberalization after the collapse of Bretton Woods. The integration of peripheral economies into this hierarchical global market of currencies and financial assets occurs unequally, with peripheral countries attracting speculative capital through high interest rates and deregulation. The article analyzes the process of financialization in Brazil since the 1980s, proposing a periodization that reveals how Brazil’s economic structure consolidated a specific type of financialization.
The rate of profit and changes in the composition of capital
Authors: Araujo Elizeu Serra de
Published: December 2024

This article discusses two aspects of the influence of the value composition of capital (VCC) on the evolution of the rate of profit. First, it shows how changes in this composition caused by variations in the value of the material elements of constant capital or variable capital affect the rate of profit. Second, it discusses the effect of organic changes in the VCC and of their combination with changes in value on the rate of profit. The conclusion relativizes the theoretical importance of the fall in the rate of profit resulting from an increase in value compared to that resulting from an increase in the organic composition and emphasizes the distinction between tendency and countertendencies in the context of the law of the tendential fall in the rate of profit, based on the distinction between the concepts of value and organic composition of capital.

Background:

Cardiogenic stroke is associated with substantial morbidity and mortality, necessitating a better understanding of its clinical characteristics for improved patient outcomes. This study aimed to identify clinical characteristics influencing short-term functional prognosis in patients with cardiogenic stroke.

Methods:

The study prospectively enrolled 212 patients with cardiogenic stroke, collecting their clinical data and laboratory results. The modified Rankin Scale score at 90 days was used to define functional prognosis, with patients having a good prognosis (modified Rankin Scale ≤2; n = 164) or poor prognosis (modified Rankin Scale ≥3; n = 48).

Results:

The poor prognosis group had higher rates of total anterior circulation infarcts (12.5% vs 0.0%; P < .001) and posterior circulation infarction (50.0% vs 38.4%; P < .001) compared with the good prognosis group. Lesion characteristics differed significantly, with the poor prognosis group exhibiting more large-area lesions (39.6% vs 18.9%; P < .001) and multiple confluent lesions (56.3% vs 24.4%; P < .001). Admission-based National Institute of Health Stroke Scale scores were higher in the poor prognosis group (median [IQR], 12 [8-18] vs 5 [4-7]; P <.001), correlating with worse outcomes. The admission National Institute of Health Stroke Scale score predicted patients’ 90-day prognosis with good accuracy (area under the curve, 0.937 [95% CI, 0.895-0.965]; P < .001), with a threshold of 7 yielding 85.42% sensitivity and 85.37% specificity.

Conclusion:

Higher admission National Institute of Health Stroke Scale scores were significantly associated with poor functional prognosis at 90 days, highlighting the importance of early National Institute of Health Stroke Scale–based assessment for improved outcomes.

There are more than 3000 species of wild mushrooms in Slovenia. These wild mushrooms represent a promising source of bioactive compounds that can also be used as a source of novel enzymes, thus offering potential economic benefits for a wide range of industries and medicine. In this work, the cellulase, xylanase, protease, and lipase activities were measured in aqueous extracts of 64 Slovenian wild mushrooms of different lifestyles (symbiotic, saprobic, parasitic). We have shown that many of the mushroom extracts tested contain a variety of specific hydrolases. Of the 64 wild mushroom extracts, 16 showed cellulase, 24 xylanase, 30 lipase, and five protease activities. These are the first reports of these enzymatic activities for some of the mushrooms tested.

In this study, kindergarten children aged 5-6 years were subjected to a motor performance test and to continuous 24-hour measurement using a multifunctional wireless holter recorder to obtain basic physiological data on heart rate, physical activity, sleep information, and autonomic nervous system activity, and to examine the relationship between these data and motor performance. In the motor performance tests, boys showed higher values than girls in the 25-m run, standing long jump, and hard tennis ball throw. The total heart rate and mean heart rate upon awakening were significantly correlated with the 25-m run. Boys showed significantly higher basal metabolism, physical activity, fat burning and total energy consumption than girls, and significant correlations were also found between the 25-m run and the hard tennis ball throw. The number of times boys got up from sleep was significantly higher than that of girls. Concerning 25-m running, jumping over both feet, and catching the ball, the right side of the body showed significant correlations, while body support duration was significantly correlated with the number of arousals. Autonomic nervous activity during sleep was divided into Pattern 1 (standard type, with low sympathetic and high parasympathetic activities), Pattern 2 (sympathetic and parasympathetic activities alternating evenly), and Pattern 3 (opposite of standard type). Boys who excelled in running, jumping, and throwing also tended to excel in physiological data, suggesting the importance of early childhood athletic play.

The Uvira health zone has never benefited from a study on low birth weight, while the neonatal mortality rate remains high. Low birth weight is an important public health indicator because of the strong association between birth weight and infant morbidity and mortality. This is a cross-sectional, retrospective study conducted over a ten-month period, from June 2021 to March 2022. In order to achieve a representative study of the city of Uvira, we identified 6 maternity hospitals willing to provide data from their facilities during the study, and spread over the 3 communes of the city of Uvira, with 2 most frequented maternity hospitals per commune. We selected births from the delivery registers of six health facilities in the city between June 2021 and March 2022 (n=802). We estimated the frequency of new borns with a birth weight of less than 2500 grs, explained the trends and also checked whether early maternal age, increased parity and small inter-genesic space deviation increased the risk of low birth weight. We describe for the first time data on low birth weight in the city of Uvira. A total of 21.1% of 802 births were associated with low birth weight. A strong correlation between low birth weight and maternal age (r=0.02, CI=95%, P-value=0.00000), parity (r=0.003, CI=95%, P-value=0.000001) and inter-genesic space (r=0.02, CI=95%, P-value=0.000809) was noted. It is important to conduct further studies to establish the cause-effect relationship for other determinants with a view to specific interventions to reduce perinatal morbidity and mortality.
