Efficient neighborhood evaluation for the Maximally Diverse Grouping Problem
Authors: Schulz Arne 
Published: December 2023

Abstract
The Maximally Diverse Grouping Problem is one of the well-known combinatorial optimization problems with applications in the assignment of students to groups or courses. Due to its NP-hardness several (meta)heuristic solution approaches have been presented in the literature. Most of them include the insertion of an item of one group into another group and the swap of two items currently assigned to different groups as neighborhoods. The paper presents a new efficient implementation for both neighborhoods and compares it with the standard implementation in which all inserts/swaps are evaluated as well as the neighborhood decomposition approach. The results show that the newly presented approach is clearly superior for larger instances allowing for up to 160% more iterations in comparison to the standard implementation and up to 76% more iterations in comparison to the neighborhood decomposition approach. Moreover, the results can also be used for (meta)heuristic algorithms for other grouping or clustering problems.
Assessment of Soil Erosion Dynamics and Vulnerable Areas in the Upper Gillo Region, Baro Akobo Basin, Ethiopia
Authors: Mengistu  
Published: December 2023

Abstract
Study Region: This has a look at specializes in the Upper Gillo place within the Baro Akobo Basin, Ethiopia
Study Focus: The objectives are to estimate soil erosion charges and become aware of vulnerable regions through the usage of the Universal Soil Loss Equation (USLE) and Geographic Information System (GIS). Through GIS evaluation of rainfall, soil traits, topography, and land cover statistics, soil loss charges and erosion-contributing elements were quantified. Results showed varying soil loss rates, with a mean annual lack of 20 lots in keeping with hectare. Steep slopes and mountainous regions skilled better fees above 50 heaps in keeping with hectare annually, even as 31.88% of the watershed had lower erosion risk
New Hydrological Insights for the Region: These findings highlight the number one driver of soil erosion inside the Upper Gillo place and the pressing need for erosion management measures. High-danger areas, together with the Gillo River, valleys, and floodplains, require on-the-spot attention. Vegetated and cultivated areas showed decreased soil loss fees, emphasizing the significance of plant life cover in erosion discount. The integration of USLE and GIS enables informed choice-making for sustainable land management inside the Baro Akobo Basin. The quantified soil loss fees and identified susceptible regions provide valuable statistics for policymakers, land managers, and stakeholders to put into effect effective erosion manipulation strategies, mainly to step forward environmental resilience and sustainable improvement

Abstract

Purpose
To investigate the clinical value of the bacterial culture of fluid in the surgical area in laparoscopic transanal total mesorectal excision (Lap-taTME) and laparoscopic total mesorectal excision (Lap-TME).
Methods
Clinical data of 106 patients who had successfully undergone radical resection of rectal cancer at gastrointestinal surgery department of the First Affiliated Hospital of Chongqing Medical University from September 2017 to August 2019 were retrospectively collected. There were 56 patients in the Lap-taTME group and 50 patients in the Lap-TME group. In the Lap-taTME group, the initial pelvic fluid, the rectal cavity fluid after purse-string suture, and the pelvic cavity fluid after anastomosis were collected and recorded as culture No.1, No.2, and No.3, respectively. In the Lap-TME group, culture No.1 and No.3 were collected as done in the Lap-taTME group. The postoperative pathology, culture results, and postoperative complications were statistically analyzed.
Results
The postoperative pathological results showed that the positive rates of distal margin, proximal margin, and circumferential resection margin were zero in both groups, and there were no significant intergroup differences in the total number of lymph nodes detected and pathological TNM stage (all P > 0.05). The positive rate of culture No.1 was zero in both groups, and there were six cases (10.7%) with positive culture No.2 in the Lap-taTME group. However, the number of patients with positive culture No.3 in the Lap-taTME group (7, 12.5%) was significantly higher than that in the Lap-TME group (0) (P < 0.05), and the number of cumulative positive culture cases in the Lap-taTME group (11, 19.6%) was significantly higher than that in the Lap-TME group (0) (P < 0.05). Pelvic infection occurred in four (7.1% of all cases) of the eleven cases with positive culture (19.6% of all cases) in the Lap-taTME group, accounting for 36.4% of the cases with positive culture (4/11). There were no significant intergroup differences in anastomotic leakage and pelvic infection (all P > 0.05).
Conclusions
Positive bacterial culture of fluid during Lap-taTME indicates an increased risk of pelvic infection after operation. Lap-taTME is more prone to intraoperative contamination than Lap-TME but does not significantly increase the risk of postoperative pelvic infection.
University Teachers’ Agency in Relation to Technology Use in Teaching: A Quantitative Investigation
Authors: Nøhr Liv , Hvid Stenalt Maria , Hagood Danielle 
Published: December 2023

This study investigates Danish university teachers’ agency in using digital technologies in teaching. Furthermore, it explores how teachers’ conduct and experienced constraints are connected to different dimensions of teachers’ agency.
The paper is based on survey responses from 344 teachers about their agentic will and power to influence aspects of technology usage in teaching. Using an exploratory factor analysis, we identify three distinct factors and their relations: 1) wanting to control digital data and having the power to do so is distinct from 2) teachers’ power and will to control the technologies adopted and 3) how technologies are applied in teaching. Furthermore, all factors correlate with the teachers’ conduct (extent to which technology facilitates education interactions), while there are factor-specific patterns to the constraints (e.g., time, experience).
The results provide a basis for revisiting teachers’ role in university decision-making. We include a discussion on the entangledness of agency across institutional levels.

Authors: Marrón Fernández Yolanda I , Martínez-Aznar María Mercedes 
Published: December 2023

El artículo describe la competencia digital de los docentes y de los alumnos desde una perspectiva internacional y nacional. Emplea un método cualitativo de carácter descriptivo, con un enfoque documental. Enuncia los programas que están realizando las comunidades autónomas españolas para la promoción de la competencia digital. Además, analiza los procedimientos de acreditación realizados en las comunidades autónomas a lo largo del curso académico 2022/23 un fenómeno de gran actualidad que implica al profesorado. También compara las competencias que deben tener los ciudadanos según el marco europeo CompDig de 2022 con el currículo español vigente para tratar de establecer una correspondencia con las competencias que adquirirán al terminar la escolaridad obligatoria.
Los resultados indican una escasa regularidad en dichos procesos y ponen de manifiesto la necesidad de revisión de la formación, tanto inicial como permanente de los docentes de nuestro país para dar respuesta a una realidad cambiante en un mundo globalizado y digitalizado. También se plantea la necesidad de un diseño de la formación del profesorado en competencia digital que tenga en cuenta la especificidad de las diferentes materias, la motivación y el compromiso con el aprendizaje, para conseguir un cambio real que impacte en el alumnado.

Abstract

This research applies artificial intelligence algorithms for optimizing the water quality monitoring network in a representative basin with intensive agricultural and livestock activities. This study used the water quality database provided by the National Water Commission (CONAGUA). Bi-monthly monitoring was registered from 2013 to 2020 for 23 water quality parameters in 23 sampling locations in tributaries and the mainstream river. Therefore, it was necessary to apply principal component analysis to reduce the dimensionality of the data and thus identify the parameters that contribute most to the variation in the water quality. This artificial intelligence algorithm promoted the ease of clustering sampling sites with similar water quality characteristics by reducing the number of variables involved in the database. The reduction highlighted nutrients (TN and TP), parameters related to dissolved organic matter (NH3-N and TOC), and pathogens such as fecal coliforms. The similarity of sampling sites was determined through hierarchical clustering using the Euclidean distance as a measure of dissimilarity and the Ward method as a grouping method. As a result, nine clusters were obtained for the rainy and dry seasons, reducing approximately 50% of the sampling sites and generating an optimized network of 11 sampling sites.

Published: December 2023

Abstract

The application of a hybrid-fruit-peel (HFP) coagulant used as an external carbon source (ECS) in both simulated water and real sewage having a low carbon source treated with sequencing batch reactor (SBR) was studied, compared with that of sodium acetate (NaAc). The impact of HFP on sludge properties (such as extracellular polymer substance (EPS), dehydrogenase activity (DHA), charged property, size, microscopic images and bacteria phase) was characterized. The results showed that as an ECS, HFP basically gave similar nitrogen removal to NaAc and also gave a similar developing trend of both dissolved oxygen (DO) and pH. HFP promoted more proliferation of microorganisms and posed higher levels of protein (PN) and polysaccharide (PS) than NaAc, but gave slightly lower DHA than NaAc. After HFP was added as an ECS, the types and quantities of microorganisms increased significantly, the effluent qualities were improved and the sludge size and extensibility became larger, which was conducive to direct contact and remove pollutants. HFP played a similar role to NaAc as ECS and can be used as a quality and slow-releasing ECS for low carbon source wastewaters.

Background
Depression is the most common psychiatric disorder among older adults. Despite the effectiveness of pharmacological and psychological therapies, many patients with late-life depression (LLD) are unable to access timely treatment. Telecare has been shown to be effective in addressing patients' psychosocial issues, while its effectiveness in serving patients with LLD remains unclear.

Objective
This study aimed to evaluate the effectiveness of telecare in reducing depression and anxiety symptoms and improving quality of life (QoL) in patients with LLD.

Methods
Databases including the Cochrane Library, Web of Science, PubMed, Embase, and EBSCO were searched for randomized controlled trials (RCTs) evaluating the effectiveness of telecare for LLD from database establishment to December 28, 2022.

Results
A total of 12 RCTs involving 1663 participants were identified in this study. The meta-analysis showed that (1) telecare significantly reduced depressive symptoms in patients with LLD compared to those in usual care (UC; standardized mean difference [SMD]=–0.46, 95% CI –0.53 to –0.38; P<.001), with the best improvement observed within 3 months of intervention (SMD=–0.72, 95% CI –1.16 to –0.28; P<.001); (2) other scales appeared more effective than the Patient Health Questionnaire-9 for LLD in telecare interventions (SMD=–0.65, 95% CI –0.96 to –0.35; P<.001); (3) telecare was more effective than telephone-based interventions for remote monitoring of LLD (SMD=–1.13, 95% CI –1.51 to –0.76; P<.001); (4) the reduction of depressive symptoms was more pronounced in patients with LLD with chronic conditions (SMD=–0.67, 95% CI –0.89 to –0.44; P<.001); (5) telecare was more effective for LLD in Europe and the Americas than in other regions (SMD=–0.73, 95% CI –0.99 to –0.47; P<.001); (6) telecare significantly reduced anxiety symptoms in patients with LLD (SMD=–0.53, 95% CI –0.73 to –0.33; P=.02); and (7) there was no significant improvement in the psychological components of QoL in patients with LLD compared to those receiving UC (SMD=0.30, 95% CI 0.18-0.43; P=.80).

Conclusions
Telecare is a promising modality of care for treatment, which can alleviate depression and anxiety symptoms in patients with LLD. Continued in-depth research into the effectiveness of telecare in treating depression could better identify where older patients would benefit from this intervention.

Published: December 2023

Endoscopic ultrasound (EUS) is a high-tech ultrasound examination that simultaneously combines the options of endoscopic and ultrasound diagnosis of diseases of the gastrointestinal tract, pancreas, bile ducts and liver. The advantages of endoscopic ultrasound over traditional transabdominal ultrasound are that the ultrasound transducer can be guided directly through the lumen of the gastrointestinal tract to the object under visual control. The EUS is the method of choice for the study of submucosal lesions in the upper gastrointestinal tract. It is the most accurate method for the detection and diagnosis of submucosal formations due to its high sensitivity, specificity, is used as the next research method after endoscopy and can provide information about the origin, size, borders, homogeneity, as well as the choice of treatment method: endoscopic or surgical one. A more important application of EUS is the determination of the stage of malignant neoplasms of the gastrointestinal tract, as it determines the treatment and predicts the disease. And the real-time strain elastography, which allows analyzing the stiffness of tissues, helps in this. The high accuracy of this study allows for the differential diagnosis of benign and malignant neoplasms. The article presents cases of examination of patients with submucosal neoplasms of the stomach who were treated in the SI “Institute of Gastroentero­logy of the National Academy of Medical Sciences of Ukraine”.

Evaluasi Penggunaan Lahan Mengacu pada Indeks Potensi Lahan dan Kesesuaiannya Terhadap Rencana Tata Ruang Wilayah di Kabupaten Wonosobo
Authors: Ndofah Tiara Ana , Santosa Purnama Budi 
Published: December 2023

Seiring pertumbuhan penduduk, kebutuhan akan lahan untuk berbagai keperluan semakin meningkat, misalnya untuk permukinan, perdagangan, industry, jasa. Hal ini mengakibatkan perubahan penggunaan lahan yang pada beberapa daerah mengorbankan lahan pertanian. Indeks Potensi Lahan (IPL) menunjukkan nilai potensi sebuah lahan dilihat dari ciri fisik lahan tersebut. IPL sering digunakan dalam evaluasi lahan berdasarkan potensinya. Penelitian ini bertujuan untuk mengevaluasi penggunaan lahan berdasarkan IPL dan kesesuaiannya terhadap RTRW Kabupaten Wonosobo. Penyusunan IPL dilakukan dengan metode Multi Criteria Analysis (MCA). Parameter IPL yang digunakan adalah kemiringan lereng, jenis tanah, batuan induk, produktivitas akuifer, dan kerawanan bencana (banjir, banjir bandang, dan tanah longsor). Peta kemiringan lereng disusun dari SRTM 30 m dan SRTM 90 m. Adapun penyusunan peta tutupan lahan dilakukan dengan digitasi On Screen Citra SPOT 6 tahun 2020 dan SPOT 7 tahun 2021. Hasil analisis menunjukkan bahwa di Kabupaten Wonosobo luas kelas IPL sangat tinggi adalah 12.224,209 Ha (12,129%), kelas IPL tinggi adalah 30.317,934 Ha (30,082%), kelas IPL sedang adalah 47.129,223 Ha (46,763 %), kelas IPL rendah 10.787,906 Ha (10,704 %), dan IPL sangat rendah adalah 323,719 (0,321 %). Selain itu, dari 20 kelas penggunaan lahan tahun 2021, presentase kebun campuran adalah sebesar 41,355%, ladang atau tegalan 17,236 %, dan sawah 12,401%. Jika dianalisis berdasarkan IPL-nya, maka penggunaan lahan di Kabupaten Wonosobo dapat dikatakan cukup sesuai dengan potensinya mengingat luas lahan IPL paling mendominasi adalah kelas IPL sedang dan tinggi yang mana secara keseluruhan penggunaan lahan yang mendominasi di kedua kelas IPL tersebut pun adalah lahan-lahan produktif yang meliputi lahan kebun campuran, ladang/tegalan, sawah, dan hutan produksi terbatas. Sebesar 71,774 % penggunaan lahan tahun 2021 sesuai, 9,335 % tidak sesuai, dan 18,891 % belum sesuai dengan rencana pola ruang Kabupaten Wonosobo Tahun 2011 – 2031.

Objective: To determine the diagnostic yields of the different types of cell indices alone or in combination with C-reactive-protein(CRP) to distinguish between Pulmonary-tuberculosis(PT) and community-acquired-pneumonia(CAP).
Methods: A retrospective cohort study was conducted in a high-complexity care center in Colombia, evaluating different types of cell indices in PT and CAP patients. A-receiver-operating-characteristic (ROC)-curve was plotted, and the area-under ROC-curve was calculated for each of these indices, as well as for CRP and procalcitonin values.Results: A total of 544 subjects were included in the final analysis. Of these, 270(49,6%) were diagnosed with PT and 274(50,4%) with CAP. Patients with CAP had significantly higher levels of leukocytes, neutrophils, monocytes, hemoglobin, hematocrit, and platelets than patients with PT (p < 0,05for-all-comparisons). Procal-citonin did not show significant differences between the groups (p=0,061). CRP has the highest ROC-curve for differentiating between PT and CAP, with ROC-curve of 0,76 (95%CI:0,71-0,88) and 0,75 (95%CI:0,71-0,80), respectively. Procalcitonin did not show discriminatory power for these two diseases, with an ROC-curve of 0,60 (95%CI:0,50-0,71).
Conclusion: CRP and blood-cell-markers were the best markers to differentiate between patients with PT and CAP. The performance of these markers was acceptable, suggesting that they could be useful in clinical setting for suspected tuberculosis or CAP.
