Authors: Ali Machrus , Rukslin Rukslin , Hasyim Cholil 
Published: November 2022

In this paper, the efficiency of photovoltaic panels is improved by adding two solar tracking systems. The solar tracking system is used to track the sun so that the photovoltaic always faces the sun. This system uses a dual axis consisting of a horizontal rotation axis and a vertical rotation axis. The motion of the horizontal axis of rotation follows the sun's azimuth angle from north to south. The motion of the vertical axis of rotation following the sun's azimuth angle from east to west is the vertical axis motion. Both types of movement are controlled using PID and Fuzzy controllers which are optimized with an artificial intelligence approach, namely Ant Colony Optimization (ACO). Experiments with PID control approach and CES control were optimized using the ACO method (Hybrid PID-CES-ACO method). In this research, PID-CES-ACO was the best model, obtained on the horizontal axis of overshot 1328 pu, the smallest undershot was 0.116, and the fastest settling time was 0.183 s, on the vertical axis the smallest overshot was 1.246 pu, the smallest undershot was 0.044, the fastest settling time was 0.163 s

Published: November 2022

In recent studies, researchers have focused on using various modalities to recognize emotions for different applications. A major challenge is identifying emotions correctly with only electrocardiograms (ECG) as the modality. The main objective is to reduce costs by using single-modality ECG signals to predict human emotional states. This paper presents an emotion recognition approach utilizing the heart rate variability features obtained from ECG with feature selection techniques (exhaustive feature selection (EFS) and Pearson’s correlation) to train the classification models. Seven machine learning (ML) models: multi-layer perceptrons (MLP), Support Vector Machine (SVM), Decision Tree (DT), Gradient Boosting Decision Tree (GBDT), Logistic Regression, Adaboost and Extra Tree classifier are used to classify emotional state. Two public datasets, DREAMER and SWELL are used for evaluation. The results show that no particular ML works best for all data. For DREAMER with EFS, the best models to predict valence, arousal, and dominance are Extra Tree (74.6%), MLP and DT (74.6%), and GBDT and DT (69.8%), respectively. Extra tree with Pearson’s correlation are the best method for the ECG SWELL dataset and provide 100% accuracy. The usage of Extra tree classifier and feature selection technique contributes to the improvement of the model accuracy. Moreover, the Friedman test proved that ET is as good as other classification models for predicting human emotional state and ranks highest. Doi: 10.28991/ESJ-2023-07-01-011 Full Text: PDF

Published: November 2022

Despite the growth of empirical evidence in this field, little review research exists that assesses the theoretical aspects, marketing drivers, and consequences of market mavens. In this study, therefore, a systematic literature review (SLR) was utilized to perform a thorough analysis of market maven literature, encompassing articles published over 23 years on the Scopus and Web of Science indexed journals. It was found that the social and psychological aspects had not been widely explored and remained the weakest pillar. The results highlight that the theory of planned behavior has been the most commonly applied theory in the literature, as it has been used in six studies. Moreover, there is a very limited understanding of the existing literature's psychological and motivational characteristics and their role in cyber-market mavenism. To the best of the authors’ knowledge, this is the first SLR that addresses market maven literature. This research offers a comprehensive study agenda that focuses on various critical areas that need more consideration, such as the cultural role of market mavens and the differentiation between the roles of market mavens and non-mavens in sharing information on social network sites. Scholars might also look at the influence of the generational difference between people and whether or not placing an age or gender limit on people is important in terms of the nature of social networks.

Published: November 2022

Since early childhood obesity has increased dramatically in the recent year, many researchers observe the relationship of excess fat mass during childhood and many health consequences including with bone health.
This review aims to examine the relationship between childhood obesity and bone health. The results are conflicting. Several results show that fat mass have a strong positive relationship with increase bone mass and bone area, while other studies found obesity may increase the risk of fracture and may be detrimental on bone health. By these findings, further studies should be conducted to examine the effect of childhood obesity and bone health, also to evaluate the mechanisms how excess fat mass may increase or reduce bone growth.
VORICONAZOLE-INDUCED HEPATOTOXICITY
Authors: Aini Siti Rahmatul 
Published: November 2022

Voriconazole, a triazole antifungal, is widely used as the first line treatment of invasive aspergillosis in patients with haematological malignancies and hematopoietic stem cell recipients. Like other triazole antifungals, voriconazole is potentially hepatotoxic. Repeated dose oral studies in rats, mice and dogs have shown the liver to be the main target organ, with a range of adaptive and functional changes such as increasing liver weight,
centrilobular hypertrophy, smooth endoplasmic reticulum proliferation and cytochrome P450 induction. Based on the Infectious Diseases society of America (IDSA)â€™s guidelines for the treatment of invasive aspergillosis,
monitoring voriconazole levels and adjusting the dosage are recommended instead of switching to alternative antifungal drugs because of better survival and improved responses on initial therapy with voriconazole. However, if hepatotoxicity occurs, voriconazole will often be discontinued. Considering this, we try to investigatethe voriconazole-induced hepatotoxicity mechanism by reviewing the literature. Based on the similarity of metabolism pathway between ketoconazole and voriconazole, we assume that the mechanism of voriconazole induced hepatotoxicity is mediated probably through N-oxide voriconazole. N-oxide voriconazole is oxidized by flavin-containing monooxygenase (FMO) on the fluoropyrimidine ring. It produces further metabolites showing toxic consequences that produces hepatic injury.

Traumatic posterior atlantoaxial dislocation without fracture of the odontoid process: illustrative case
Authors: Liu Huan-Dong , Li Ning , Miao Wei , Su Zheng , Cheng Hui-Lin 
Published: November 2022

BACKGROUND
Traumatic posterior atlantoaxial dislocation without fracture of the odontoid process is extremely rare. Only 24 cases have been documented since the first patient was reported by Haralson and Boyd in 1969. Although various treatment strategies are reported, no consensus has been yielded.

OBSERVATIONS
A 58-year-old man experienced loss of consciousness and breathing difficulties after being struck by a car from behind. An immediate computed tomography scan showed subarachnoid hemorrhage, a posterior atlantoaxial dislocation without C1–2 fracture, and a right tibiofibular fracture. After the patient’s respiration and hemodynamics were stabilized, closed reduction was attempted. However, this strategy failed due to unbearable neck pain and quadriplegia, resulting in surgical intervention with transoral odontoidectomy and posterior occipitocervical fusion. The patient developed postoperative central nervous system infection. After anti-infective and drainage treatment, the infection was controlled. At 1-year follow-up, the patient did not complain of special discomfort and was generally in good condition.

LESSONS
The authors report their experience with transoral odontoidectomy and concomitant posterior occipitocervical fusion in a case of posterior atlantoaxial dislocation without related fracture. Although these procedures are highly feasible and effective, particular attention should be paid to their complications, such as postoperative infection.
Coexisting ossification of the posterior longitudinal ligament, intramedullary hemangioblastoma, and syringomyelia of the cervical spine: illustrative case
Authors: Li Chi-Ruei , Lee Cheng-Ying , Cheng Wen-Yu , Li Hsin-Ni , Liao Chih-Hsiang , Shen Chiung-Chyi 
Published: November 2022

BACKGROUND
Ossification of the posterior longitudinal ligament (OPLL) is a rare but potentially devastating cause of severe spinal cord compression and degenerative cervical myelopathy. Because OPLL is rarely accompanied by prominent syringomyelia, when both are observed, other causes of syringomyelia should be considered. Simultaneous presentation of OPLL and hemangioblastoma of the cervical spine is a rare encounter and has never been reported in the English-language literature.

OBSERVATIONS
The authors present a case of a 64-year-old man with muscle weakness of the right upper limb and worsening dysesthesia of the right thumb and index finger. Noncontrast magnetic resonance imaging (MRI) of the cervical spine from another institution revealed OPLL from the C2 to C6 levels with severe spinal cord compression and prominent syringomyelia. Repeated MRI with contrast showed an intramedullary tumor, about 11 mm in diameter, at the right posterior aspect of the C4 level. The authors performed laminectomies from C1 to C6 with posterolateral fusion and removed the C4 tumor. Pathohistological examination of the tumor demonstrated hemangioblastoma.

LESSONS
Careful evaluation of the preoperative imaging study is extremely important in surgical decision making. Although rare, concomitant cervical hemangioblastoma should be listed in the differential diagnosis when OPLL is accompanied with prominent syringomyelia.
Authoritarianism as a “Wicked Problem” in Contemporary International Relations
Authors: Ficek Ryszard 
Published: November 2022

This study aims to explore the concept of authoritarianism, which – presented in terms of the “wicked problem” of the contemporary world – seems to be a severe challenge to present-day International Relations (IR), both theoretically and practically. The author of the article defines the concept of authoritarianism as a form of the political system in which the power and material resources of the state have been centralised, appropriated, and put at the disposal of either an individual or an elitist group “in power.” In this way, the possibilities of integrating the authoritarian state – both politically and economically – with the global system of international relations are limited, and the vital administrative institutions of the state have been manipulated and appropriated. The applied research method allows for interpreting the discussed issues in a complex – albeit specific – systemic form, characteristic not only for politically fragile or declining countries and regions but also for politically stable and economically developed ones. The author’s analysis allows for the presentation and reinterpretation of the issue of contemporary authoritarian regimes concerning international relations in terms that not only define but often legitimise some of the most despotic, autocratic, and hegemonistic forms of the political systems in modern times.
Hypomagnesemia and Type-2 Diabetes Mellitus
Authors: Karmakar Pijush , Jahan Iffat , Islam Md Zakirul 
Published: November 2022

Diabetes mellitus (DM) has been suggested to be the most common metabolic disorder associated with several macrovascular and microvascular complications. Hypomagnesemia has been reported to occur at an increased frequency among patients with type-2 DM. Those who have poor glycemic control and longtime DM are more likely to decrease the blood magnesium (Mg) level. Mg deficit may also coexist with deficiencies of other dietary elements, such as vitamins, calcium (Ca++) and potassium (K+). Despite numerous reports linking hypomagnesemia to chronic diabetic complications, attention to this issue is poor among clinicians. This article reviews the literature on physiology & biochemistry of Mg++ diagnosis and incidence, features, causes, complications and management of hypomagnesemia in patients with type-2 DM.

Diagnostic impact of CEA and CA 15-3 on monitoring chemotherapy of breast cancer patients
Authors: Hasan Diya 
Published: November 2022

Objective: Serum tumor markers has been evolved as an effective tool to determine prognosis and treatment efficiency in different types of cancer. The aim of this study was to explore the chemotherapy monitoring efficiency and prognostic sensitivity of tumor associated cancer antigen 15-3 (CA 15-3) and carcinoembryonic antigen (CEA) markers in early (II) and late (IV) clinical stages of breast cancer patients.

Methods: CA 15-3 and CEA serum levels were assessed in 56 breast cancer patients at early II (n = 26) and late IV (n = 30) clinical stages with primary inclusion criteria: who received adjuvant chemotherapy AC (Adriamycin & Cyclophosphamide) or AC-T (Adriamycin & Cyclophosphamide followed by Taxane) regimes and human epidermal growth factor receptor 2 (HER2) negative by using particle enhanced turbid metric assay.

Results: Higher elevation of CA 15-3 as compared to CEA in pre-treatment group of breast cancer patients as compared to healthy control was observed. Late-stage patients showed higher positive serum levels as compared to early-stage one for both markers with preference of CA 15-3 over CEA. AC-T chemotherapy regime treatment in both clinical stages revealed significantly higher level of both markers as compared to AC regime with preference of CA 15-3 over CEA at late stage. Both markers levels were significantly higher in late-stage group as compared with early-stage ones for both chemotherapy regimens.

Conclusion: CA 15-3 is more efficient as prognostic monitoring marker in comparison with CEA and revels a positive connection between chemotherapy regime system and staging, more observed in late-stage.
