Authors: Herdian Cevi , Kamila Ahya , Agung Musa Budidarma I Gusti
Published: January 2024

Di dalam pemodelan pembelajaran mesin (Machine Learning), data terbagi menjadi jenis data numerik dan jenis data teks. Tetapi Machine Learning lebih cenderung efektif dalam mengenali pola pada jenis data numerik karena algoritma Machine Learning, terutama yang berbasis statistik dan matematika, dirancang untuk memproses dan menganalisis data numerik. Sehingga bentuk data teks harus dirubah ke dalam bentuk data numerik yang merupakan bagian dari Feature Engineering. Pada penelitian ini, peneliti membanding sebuah hasil akurasi dari prediksi Machine Learning yaitu linear regresi pada teks label data yang telah dilakukan perubahan menjadi numerik dengan metode Feature engineering Label Encoding dan juga Feature Engineering One-Hot Encoding. Pada penelitian ini didapatkan hasil R-Square untuk Label Encoding 0.54 dan R-Squared untuk One-Hot Encoding 0.85 (hasil One-Hot Encoding lebih baik). Sehingga tentu saja yang harus dipilih untuk model yang dibuat adalah Feature Engineering One-Hot Encoding. Untuk kedepannya bisa dilakukan pengujian dengan metode lain untuk merubah data teks menjadi numerik seperti Bags of Words (BoW), Term Frequency-Inverse Document Frequency (TF-IDF), dan yang lainnya.

Published: January 2024

Background: One mode of action of 5-ALA with SFC is the induction of Heme Oxygenase-1, a key regulator in anti-oxidative and immunological processes, leading to the hypothesis that the product supports faster recovery from infections such as COVID-19. Objective: The main objective was to assess the safety and immune-supportive potential of the food supplement 5-aminolevulinic acid phosphate (5-ALA) with sodium ferrous citrate (SFC) in patients with COVID-19 when co-administered with standard of care medications (SoC).Methods: A patient group with moderate COVID-19 symptoms (four males and three females, mean age 43 years) and one group with severe symptoms (12 males, mean age 48 years) received daily oral doses of 500 mg/750 mg 5-ALA with 286 mg/430 mg SFC for the first 7 days (≤7.5 times higher than the recommended dose for the marketed product). For the subsequent 21 d, the daily dose was reduced to 250 mg 5-ALA with 143 mg SFC in both groups. Adverse events and several immunological laboratory parameters were collected. Moreover, the mean hospital stay was compared with historical data of patients solely treated with SoC. Results: Two patients in the moderate group showed elevated liver enzymes; however, these seemed to be related to SoC. In the severe group, one patient experienced constipation. No serious adverse events were observed. In the severe group, a significant decrease of C-reactive protein (109.42 5.41 mg/L; p <0.005), procalcitonin (0.87 to 0.07 ng/mL; p <0.005), and interleukin 6 (20.07 to 5.06 pg/mL; p <0.05) and an increase of the cluster of differentiation 4 (250 to 880 cells/µl; p <0.05) and the cluster of differentiation 8 (190 to 623 cells/µL; p <0.05) were detected. The hospital stay of the severe group was markedly shorter (8 d only) than that of the control group (16 d).Conclusions: 5-ALA with SFC was evaluated as safe for administration in COVID-19 patients. Moreover, there were signals detecting its immune-supportive potential. The small number of included patients limits interpretation of the significance of the results; however, the study is useful in deciding future development strategies. Trial Registration: The study was registered on ClinicalTrials.gov (https://clinicaltrials.gov/) on September 06, 2020 (registration no. NCT04542850.Keywords: 5-aminolevulinic acid; COVID-19; SARS-CoV-2; food supplement
Digital skills within the Public Sector: A missing link to achieve the Sustainable Development Goals (SDGs)
Authors: Cordella Antonio , Gualdi Francesco , van de Laar Mindel
Published: January 2024

Academic literature has mostly discussed digital skills concerning end-users’ capability to access and use single technologies. Against this background, the paper sheds light on a missing element: the digital literacy of those who frame ICT-mediated policies that pursue sustainable development. The paper offers a novel conceptualization of digital skills as the capabilities to understand the socio-technical assemblages that emerge in social contexts after the adoption of ICT-mediated policies. Exploring the case study of the United Kingdom’s Government Digital Service, the paper argues that empowering public administrators and civil servants with these digital skills is paramount to design, implement, and manage ICT-mediated policies that aim to achieve Sustainable Development Goals.

Background: 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) regulates intracellular cortisol and its inhibition by the small molecule inhibitor, Xanamem™, may provide a disease-modifying strategy for Alzheimer’s disease (AD). Animal models suggest a range of 30–60% enzyme inhibition may suffice to provide neuroprotection. Objective: To determine the regional brain occupancy of 11β-HSD1 by Xanamem™ in cognitively normal participants (CN) and mild cognitive impairment (MCI)/mild AD patients to investigate potential dosing ranges for future efficacy studies. Methods: Seventeen MCI/AD and 23 CN were included. Regional brain time-activity curves (TAC), standardized uptake values (SUV40–60) and volume of distribution (VT) from Logan plot with image derived input function from 11C-TARACT positron emission tomography (PET) were used to assess the degree of 11β-HSD1 occupancy by increasing doses of Xanamem™ (5 mg, 10 mg, 20 mg or 30 mg daily for 7 days). Results: All measures showed high 11β-HSD1 occupancy with Xanamem to similar degree in CN and MCI/AD. The dose-response relationship was relatively flat above 5 mg. Respective median (interquartile range [Q1-Q3]) 11β-HSD1 occupancy in the MCI/AD and CN groups after treatment with 10 mg Xanamem were 80% [79–81%] and 75% [71–76%] in the neocortex, 69% [64–70%] and 61% [52–63%] in the medial temporal lobe, 80% [79–80%] and 73% [68–73%] in the basal ganglia, and 71% [67–75%] and 66% [62–68%] in the cerebellum. Conclusions: TAC, SUV40–60, and VT measures indicate Xanamem achieves high target occupancy levels with near saturation at 10 mg daily. These data support exploration of doses of≤10 mg daily in future clinical studies.

Conventional low-frequency electromagnetic wave (LFEM) transmitting antennas are enormous in size, which limits the application of LFEM in underground space. Rotating-magnet Based Mechanical Antennas can realize the miniaturization of low-frequency antennas, which is expected to bring new possibilities for underground electromagnetic detection or ground penetration communication. Firstly, this paper establishes a synthetic field method for solving the electromagnetic field of a rotating permanent magnet in the air-earth cross-domain case. The method equates the magnet as an orthogonal superposition of vertical and horizontal dipole sources, and the phase difference between vertical and horizontal dipole sources is 𝜋/2. Based on the half-space theory of multilayer planar media, the quasi-analytical solution of the electromagnetic field of the magnetic dipole in the case of air-earth trans dimensionality can be found by superposition. Secondly, based on the finite element numerical model, the trans-earth propagation characteristics of the electromagnetic field excited by the rotating permanent magnet across the air-earth dual domain are studied. At the same time, the radiation characteristics in the rotating plane of the permanent magnet are also studied. Again, this paper systematically investigates the influence of parameters such as earth conductivity, emission frequency, and propagation distance on the electromagnetic field propagation. Finally, the principle prototype is developed and experiments are carried out. The results show that the finite element numerical model established in this paper is correct, the experimental results are consistent with the theoretical values, and a field strength signal of 0.9 nT can be received at 20 m. The research work in this paper lays the foundation for the future use of mechanical antennas for electromagnetic detection and ground penetration communication.

BACKGROUND: Lung cancer is one of the most common malignant tumours that threaten human health globally. Radical resection under thoracoscopic guidance has been accepted as the major therapeutic option for treating lung cancer clinically. However, the procedure still has some adverse impacts on the comfort of patients following thoracoscopic surgery. OBJECTIVE: To analyse the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery and to evaluate patient comfort. METHODS: With 210 patients with lung cancer undergoing endoscopic surgery as the participants, this study was performed to assess the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery, with the assessment performed by eight experts. RESULTS: The postoperative comfort scale included 28 items and consisted of four dimensions (physiological, psychological, socio-cultural and environmental). The total Cronbach’s alpha coefficient of the scale was 0.851, and the split-half reliability coefficient was 0.875. Meanwhile, the content validity index (CVI) was 0.875∼1, and the scale-level average CVI was 0.99. The Chi-square/degree-of-freedom ratio of construct validity was 2.844, suggesting a good model-fitting. Furthermore, the overall average score of patient comfort was 3.72 ± 0.57, with scores ranging between 3.59 ± 0.71 and 3.83 ± 1.06 across all four dimensions, with the lowest score in the physiological dimension. CONCLUSION: The postoperative comfort scale has good reliability and validity and can be applied for the postoperative comfort assessment of patients undergoing endoscopic surgery for lung cancer. Overall, the degree of patient comfort in this assessment was moderate, meaning targeted measures may be required to further improve patient comfort, especially in the physiological dimension.

Bent Functions and Strongly Regular Graphs
Authors: Smaldore Valentino
Published: January 2024

The family of bent functions is a known class of Boolean functions, which have a great importance in cryptography. The Cayley graph defined on \(\mathbb{Z}_{2}^{n}\) by the support of a bent function is a strongly regular graph \(srg(v,k,\lambda,\mu)\), with \(\lambda=\mu\). In this paper we list the parameters of such Cayley graphs. Moreover, a condition is given on \((n,m)\)-bent functions \(F=(f_1,\ldots,f_m)\), involving the support of their components \(f_i\), and their \(n\)-ary symmetric differences.

Introduction: Surgical treatment of abdominal aortic aneurysms poses a significant challenge in the field of vascular surgery, with numerous factors influencing operative technique and surgical outcome.

This study aimed to assess the outcomes of open surgical treatment for patients with abdominal aortic aneurysms at the Vascular Surgery Service of University Hospital Centre “Mother Teresa” Tirana and provide recommendations for improving outcomes.

Material and Methods: A single-center, non-randomized, retrospective study of the results of open surgical treatment of abdominal aortic aneurysms in 206 patients from January 2008 to December 2015 was performed at the Vascular Surgery Service of University Hospital Centre “Mother Teresa” Tirana. The study only included patients with a histologically confirmed diagnosis of abdominal aortic aneurysm, while patients with ruptured abdominal aortic aneurysm were excluded.

The study evaluated the incidence of abdominal aortic aneurysms, clinical and imaging findings of the disease (ultrasound, tomographic, and arteriographic), frequency of involvement of the iliac artery in the pathological process, and postoperative complications. Transabdominal access was the most commonly utilized, while retroperitoneal access was deemed the safest. No significant differences in recurrence rates were noted between the two approaches.

Results: During the study period, 206 patients underwent surgery for AAA and met the inclusion criteria. Of these, 188 (91.3%) were male and 18 (8.7%) were female. The mean age of the patients was 67.8±5.7 years, with 67.7±5.9 years for men and 69±3.1 years for women. There were no statistically significant differences in age between genders (p>0.05).

Conclusion: In all other cases of abdominal aortic aneurysms, surgical treatment should be strongly recommended. Finally, given the clinical benefits of using surgical treatment of asymptomatic aneurysms to reduce mortality, it is necessary to conduct an economic assessment of the feasibility of abdominal aortic aneurysms screening in the population over 55 of the age of both sexes.
