Novel Particle Swarm Optimization Algorithm to Solve the Internet Shopping Optimization Problem with Shipping Costs

In this paper, we approach the Internet Shopping Optimization Problem with Shipping Costs (IShOP), an NP-hard-relevant problem in the current e-commerce environment. To our knowledge, several solution metaheuristic algorithms have been reported in the literature. In this paper, we propose a novel Particle Swarm Optimization algorithm (PSO) to solve the problem. PSO incorporates a neighborhood diversification technique (NDT), a local search (LS) technique, and an adaptive parameter tuning (APT) method. The proposed algorithm (NDTLSAA-PSO) includes two techniques at the end of each iteration to avoid premature convergence in the search process, balancing exploration and exploitation in selecting candidate solutions. A comparison of the performance of the proposed algorithm has been made against the performance of the best state-of-the-art memetic algorithm solution of the IShOP. A total of 90 instances classified into three groups of small, medium, and large sizes were resolved. The Wilcoxon and Holm non-parametric tests were applied to validate the significance of the differences observed between these two algorithms. The results show that the proposed NDTLSAA-PSO algorithm is superior to the memetic algorithm. In addition, the proposed algorithm obtains the best results in all the in-stances evaluated in terms of quality.

Comparing the effectiveness of educational videos and booklets in enhancing knowledge about odontogenic infections and awareness about seeking dental treatment

Objective: Odontogenic infections are common but often disregarded due to a lack of awareness and knowledge about oral health. Effective health promotion through educational media can enhance understanding and encourage better oral hygiene practices. This study at Universitas Airlangga Academic Dental Hospital is conducted using visual and audiovisual media to educate patients, aiming to assess the efficacy of these media in increasing knowledge and awareness about odontogenic infections, ultimately promoting dental treatment-seeking behaviour. Material and Methods: One hundred eighty-two participants from the Universitas Airlangga Academic Dental Hospital completed the questionnaires to assess knowledge and awareness score increase using either videos or booklets. Results: The statistical test results using the non-parametric Wilcoxon test indicate that both methods influenced the knowledge and awareness scores. The Mann-Whitney test showed P=0.000, which means that the post-test scores of both methods were significantly different. Regarding N gain analysis, the increase in knowledge and awareness was higher when using booklets, with average scores of 2.5585 and 1.7457, compared to using videos, which resulted in increases of 0.3680 and 0.1683, respectively. Conclusion: Booklets were more effective than videos in increasing knowledge about odontogenic infections and awareness of seeking dental treatment.

Factors such as regular lifestyle habits including diet, sleep, and exercise; sudden changes in lifestyle, mood swings, sexual tendencies and irrational beliefs such as suicide, as well as difficulties in adhering to daily routines, financial resources, sudden lifestyle changes, mood swings, and bipolar disorder; sudden changes in sexual tendencies and bipolar disorders have no direct relationship.

Association between paediatric eye injuries, later aca-demic success and social performance

<p><strong>Aim</strong> <br />To investigate an association between eye injury and later academic and social performance.<br /><strong>Methods</strong> <br />A retrospective longitudinal study of taking measurements multiple times was conducted including all severe eye injuries admitted during 2011-2017 at the main regional clinic to investigate changes in academic success and social inclusion before and after an injury. Parents/caregivers were surveyed asking questions on academic performance, and community/social involvement. In 2023 data on employment status were obtained. Kappa (ĸ) and non-parametric Wilcox-on signed-rank test for multiple comparisons were used. For association of employment status and post-injury visual acuity Fisher score was tested.<br /><strong>Results</strong> <br />The total sample for assessing social inclusion and academic success was 36 and 25 children, respectively. In the following academic year ĸ agreements decreased from 0.88 (p<0.001) comparing pre-injury with a one-year post to 0.5106 (p<.0001) in the second year and 0.4750 (p=0.003) in the third, suggesting a deteriorating trend. A comparison of academic success before injury to two and three years after injury showed the trend significantly worsening with time (p=0.005, and 0.003, respectively). No association between an eye injury and social inclusion, as well as between employment and final visual acuity was noticed. <br /><strong>Conclusion</strong> <br />Our findings suggest no association between social inclusion, employment, and eye trauma, while in later years academic success may be more impacted by the eye injury. Due to eye injury unpredictability in childhood age, both an informed and supportive climate environment at home and school is essential to minimize deleterious responses to eye trauma.</p>

Impact of Joint Laxity on 2-Year KOOS Outcomes of Posterior Stabilized Total Knee Arthroplasty.

The objective of this study was to determine relationships between intraoperative posterior cruciate ligament (PCL) sacrificing posterior stabilized (PS) total knee arthroplasty (TKA) laxity measurements throughout flexion and patient outcomes at 2 years post-TKA and to define clinically relevant laxity thresholds to optimize patient outcomes.In a single-surgeon study, PCL sacrificing TKA using a robotics-assisted platform with a digital joint tensioning device was performed in 115 knees in 115 patients. Final intraoperative joint laxity was recorded, and 2-year Knee Injury and Osteoarthritis Outcome Scores (KOOSs) were obtained. A Simulated Annealing optimization algorithm was used to identify medial and lateral laxity windows which maximized the 2-year KOOS pain score. Wilcoxon nonparametric tests were used to compare outcomes between groups.Significant associations were found between intraoperative joint laxity and 2-year KOOS pain outcomes throughout flexion. Clinically relevant laxity windows were defined medially and laterally in mid-flexion and flexion for improved outcomes, whereas only a lateral laxity window could be defined in extension. When all laxity windows were satisfied, a 14.5-KOOS point improvement was found (97.2 vs. 77.8, p = 0.0060) compared to knees which did not satisfy any window. Improvements in Activities of Daily Living (Δ8.8, p = 0.0143), Sports (Δ22.5, p = 0.0108), and Quality of Life (Δ18.7, p = 0.0011) KOOS subscores were also found in knees which satisfied all windows versus 0-1 window.Intraoperative joint laxity is associated with postoperative outcomes in a PS knee design, wherein patients balanced within identified laxity targets reported improved outcomes over those that did not. Clinically significant thresholds were defined and were predominately found in mid-flexion and flexion for medial and lateral laxity. When target windows were combined further improved outcomes were identified.

Relationship between family function and anxiety among nurses during the COVID-19 pandemic: a mediating role of expressive suppression

BackgroundThe aims of the present study were to investigate the incidence of nurses who suffered anxiety during the COVID-19 pandemic and to explore how expressive suppression influences the relationship between family function and anxiety.MethodsThis study used cross-sectional research and simple random sampling. A total of 300 questionnaires were distributed and 254 questionnaires were qualified after invalid questionnaires were proposed, thus a total of 254 female nurses from a tertiary hospital were included in this study. The measurement included General demographic questionnaires, the Self-Scale Anxiety, Scale (SAS), Emotion Regulation Strategies Questionnaire (ERQ), and Family Function Assessment (FAD). T-test, nonparametric Wilcoxon or Kruskal-Wallis test, χ2 test, Pearson or Spearman correlation analysis, multiple stepwise regression and bootstrap methods was performed to analyze the data.ResultsIn this study, 22.4% of the nurses exhibited anxiety symptoms, with 17.7% eliciting mild anxiety symptoms, 4.3% showing moderate anxiety symptoms and 0.4% with severe anxiety symptoms. Family function and expressive suppression were positively associated with anxiety severity. And family function influenced anxiety among nurses via direct and indirect (Expressive suppression -mediated) pathways.ConclusionsExpressive suppression partially mediated the influence of family function on anxiety symptom. To this end, nurse administrators should establish a robust mental health support system encompassing psychological counseling and emotional support groups. Furthermore, nurse administrators should consistently inquire about nurses’ family situations, encourage nurses to articulate their emotions and needs candidly, both within the domestic sphere and the workplace, while refraining from excessive self-repression.

Assessment of Intraday Variations in Skin Indentation Resistance.

Information about the mechanical properties of skin and their changes with age and other conditions is important to help characterize skin physiology and pathological changes. One method to obtain this information is to measure the force required to indent the skin to a specified indentation depth (FORCE). This process measures the tissue's resistance to indentation or its compressibility and is related to the tissue's elastic modulus. Since such measurements are made in clinical and other settings at various times of day (TOD), it is useful to estimate the extent of intraday variations in FORCE that may be expected. This report focuses on this issue. FORCE was self-measured on the volar forearm, 5 cm distal to the antecubital fossa, every two hours from 08:00 to 24:00 hours on two consecutive days by 12 medical students (six females and six males) who were trained in the measurement process using an indentation device (SkinFibroMeter). Variability in FORCE versus TOD was analyzed using the nonparametric Friedman test and differences between genders by the nonparametric Wilcoxon test. Differences between the first day (day 1) and the second day (day 2) were tested at each TOD. The whole-body fat percentage (FAT%) and water percentage (H2O%) were determined for each participant via bioimpedance measurements at 50 KHz. The age and BMI of the combined group (mean ± SD) were 24.5 ± 1.5 years and 23.2 ± 3.3 kg/m2.The overall average FORCE (mean ± SD) for the day over the 16 hours was 84.1 ± 22.7 mN and for day 2, it was 83.4 ± 28.5 mN with no significant difference between day 1 and day 2. For females, the overall two-day average FORCE (mean ± SD) over the 16 hours was 81.8 ± 20.3 mN and for males, it was 85.7 ± 30.1 mN with no significant difference between them (p = 0.271). Overall, there was no statistically significant difference in FORCE among TOD (p = 0.568). FORCE was not correlated with either FAT%, HTO%, or BMI. The findings indicate no statistically significant variation in indentation force in females, males, or combined concerning the TODof the measurement or differences between consecutive days at corresponding times. This suggests that whether such measurements are done in a research setting or within a clinic, they can be done at various TODwith minimal expected variation for a given subject. However, an extension of these findings to persons with skin conditions or ages not herein evaluated must await further study.

Regional features of the incidence of diseases of the musculoskeletal system and connective tissue during the COVID-19 pandemic in the Volga Federal District.

Diseases of the musculoskeletal system (MSMS) are highly common among the population, causing high rates of temporary and permanent disability in those affected. The problem is also determined by the wide age range of the sick — from young to elderly, which dictates the need to assess the prevalence and regional characteristics of musculoskeletal pathology among the population, including those of working age. The purpose of the study is to investigate the regional features of the primary incidence of the adult population of working age in the Volga Federal District (VFD) with diseases of class ICD-10 XIII (M00‑M99) «Diseases of the musculoskeletal system and connective tissue» during the COVID-19 pandemic in 2020–2021. Methods of descriptive and applied statistics were used in the research process. Statistical collections with information on the incidence of BCM in the adult population and the population over working age were studied. For a comparative assessment, we used the construction of a 95 % confidence interval for the average incidence value for the period 2012–2019. method of generating repeated samples (bootstrap). Growth rate ( %) of the incidence rate in 2020–2021. calculated to average values for 2012–2019. Using the non-parametric Wilcoxon test, the differences between the values of all studied indicators and primary incidence (PI) for 2020–2021 (p) were assessed. The variability of indicators was assessed using coefficients of variation (Cv). For statistical processing of the generated database, the Microsoft Excel program and the Wolfram Research Mathematica v.11.3 system were used. During the studied period, the adult population living in the Volga Federal District was characterized by a decrease in the incidence of diseases of the musculoskeletal system. Significant fluctuations in primary incidence were revealed. In 2020–2021 For most of the studied indicators, there was an increase in Cv of primary morbidity, differences in morbidity levels for individual nosological forms of diseases of the musculoskeletal system in the regions of the district. During the pandemic of the new coronavirus infection in the Volga Federal District, multidirectional changes in the levels of primary incidence of diseases of the musculoskeletal system were observed, which was most likely due to the limitation of the provision of specialized medical care in certain regions.

Two-Year Mortality Predictors in Fragility Fractures-A Medical Records Review Study.

To evaluate two-year mortality predictors in all subtypes of fragility fractures. Medical records review, single-center study with Portuguese patients with fragility fractures; A univariate analysis, with chi-square for categorical variables and parametric t-student and non-parametric Wilcoxon tests for continuous variables, was performed. Posteriorly, a survival analysis, with subsequent Cox regression was conducted to establish independent risk factors/ predictors of two-year mortality in fragility fractures. 758 patients were enrolled in the study. We found a total of 151 deaths within the first two years post-fracture. On Cox regression, older age [OR1.10 CI (1.05-1.11)], male sex [OR1.85 CI(1.24-2.75)], anemia at baseline [OR2.44 CI(1.67-3.57)], malignancy [OR4.68 CI (2.13-10.27)], and multimorbidity [OR1.78 CI(1.11-2.87)] were found as independent predictors for two-year post-fracture mortality. Our study suggests that male sex, older age, anemia, malignancy, and multimorbidity are mortality predictors in the first two years after fragility fractures, reinforcing the importance of comorbidity management in preventing or, at least, minimizing adverse outcomes following fragility fractures.

ExoBand, A Passive Wearable Device as a Walking Aid in Neuromuscular Patients: First Quantitative Assessment.

Exoband (by Moveo, Padova, Italy) functions as a walking brace, comprising a belt and two leg loops connected by a mechanism that stores energy during the initial phase of the gait cycle and releases it in the subsequent phase. This enhances hip flexor thrust, leading to functional improvement in walking for individuals with conditions characterized by proximal weakness. It has been approved as a passive wearable device for individuals with impaired walking abilities. Objective of this study was to establish a protocol to assess the use of Exoband in patients with various neuromuscular disorders. This exploratory retrospective study includes consecutive patients diagnosed with neuromuscular disorders (CIDP, motor polyneuropathy, MND), exhibiting a proximal involvement and gait abnormalities. The evaluation protocol incorporated specific walking-related outcome measures, the 10-meter walk test (10mWT), Time-up-and-go test (TUG), and 2-minute walking test (2MWT). The assessments were conducted both with and without the Exoband under standard conditions. Eight patients (6 males, aged 60-78 years) were tested. An increase in velocity was observed in the 10mWT (median 13.4 sec, IQR 12.0-15.7 vs. 12.2 sec, IQR 11.3-14.2 seconds, p < 0.05) and the TUG (14.0 sec, IQR 13-16.2 vs 13.35 sec, IQR 11-13.8; p < 0.05, by non-parametric Wilcoxon test), and a trend of increase in 2MWT (median 88.2 vs 92.6 m, n.s.). Six out of 8 patients reported subjective benefits from the very first use, including improved walking stability, speed, confidence, and reduced fatigue. Our protocol provides a quantitative assessment of Exoband usefulness for patients affected by neuropathies with gait abnormalities. Further investigations are warranted to assess the long-term effects of its regular Exoband use, its efficacy in specific neuromuscular diseases, and its potential role as a rehabilitation device.

Poster 382: Predictors of Clinical Outcomes and Quality of Life after Sternoclavicular Joint Reconstruction with Hamstring Tendon Autograft

Objectives: Instability of the sternoclavicular joint (SCJ) is a rare but potentially devastating pathologic condition, particularly when it occurs in young or active patients. SCJ reconstruction using hamstring tendon autograft is a commonly used treatment option, yet results are limited to small case series, to date. To date, studies on baseline preoperative demographic factors and their association with postoperative outcome are limited. The objective was to assess the clinical and sport specific outcomes and survivorship after SCJ reconstruction using hamstring tendon autograft in patients suffering from SCJ instability and to determine whether baseline demographic factors were associated with postoperative outcomes or patient satisfaction. Methods: Patients who underwent SCJ reconstruction with a hamstring tendon autograft for SCJ instability between October 2005 and October 2020 were enrolled in this retrospective, monocentric study. At a minimum of 2-years postoperatively, clinical outcomes were collected, including the following patient reported outcomes (PROs): the 12-Item Short Form Survey (SF-12) physical component summary (PCS) and mental component summary (MCS) scores, American Shoulder and Elbow Surgeons (ASES) score, Quick Disabilities of the Arm, Shoulder and Hand (DASH) score, Single Assessment Numeric Evaluation (SANE) score, VAS pain score, VAS pain at worst and subjective postoperative satisfaction with the procedure (0 = very unsatisfied to 10 = very satisfied). Sport specific parameters were investigated via questionnaire. The predictive role of patient demographic factors, including age, sex, and injury in dominant arm, on postoperative PROs and satisfaction at short term follow-up was evaluated using bivariate analysis. According to their respective distribution, continuous variables were compared employing a parametric unpaired t test or the non-parametric Mann–Whitney U test. Categorical variables were compared performing the binary Fisher’s exact test or the Chi-square test. The non-parametric Wilcoxon test for two related samples was used to compare pre- and postoperative values of each outcome parameter. Spearman rank correlations coefficients were calculated in the predictive factor analysis. Results: A total of 49 patients (age: 29.6 ± 16.2 years, range 13.8-67.1, 27 females) were included in the final analysis. Surgery was performed on the dominant shoulder in 26 (63.4%) of the cases. At a mean follow-up of 3.9 ± 2.1 years, all PROs had significantly improved. These included the SF12 PCS (40.4 ± 6.8 to 52.6 ± 6.9, p&lt;0.001), ASES (54.9 ± 20.4 to 91.0 ± 11.3, p&lt;0.001), QuickDASH (41.2 ± 18.5 to 10.2 ± 9.1, p&lt;0.001); SANE (50.2 ± 21.1 to 88.3 ± 8.8, p&lt;0.001), VAS pain (4.4 ± 2.6 to 0.8 ± 1.4, p&lt;0.001) and VAS pain at its worst (7.4 ± 2.5 to 3.3 ± 2.6, p&lt;0.001). The median postoperative satisfaction score was 9 (1-10). Revision-free survivorship was 95.9%. Of those, all patients returned to athletic activity. However only 45% of the overhead athletes returned to their preinjury level. Male patients had a significantly lower VAS pain at worst compared to female patients (2.6 ± 2.6 vs. 4.1 ± 2.4; p=0.045), higher age was significantly correlated with a worse Quick-DASH score (correlation coefficient: 0.314*; p=0.036) and overhead athletes had a significantly lower propensity to return to sports compared to non-overhead athletes (p=0.043). Conclusions: The significant improvements in clinical and sports specific outcomes and high patient satisfaction after SCJ reconstruction with a hamstring autograft demonstrate the success of this procedure in treating SCJ instability. Male sex and younger patient age are associated with superior outcomes, while overhead athletes have to be counseled about difficulties of returning to preinjury level of sport, postoperatively.

Research on the performance of GMCBO methodology based on model updating of a pedestrian bridge

Consider the loss of diversity of the bodies at the later optimization stage and the low efficiency of the global searching ability of the traditional colliding bodies optimization algorithm in dealing with complex optimization issues of practical structures. Herein, an improved colliding bodies optimization method combing Gaussian-white-noise mutation and innovative collision mode is proposed. The introduction of Gaussian-white-noise is mutating the positions of the selected bodies and enriching the diversity during the whole optimization process. The changed collision mode from ‘one to one’ to ‘one to best’ is accelerating the process to global extremum. During searching the global extremums of the 12 test functions which are unimodal, multimodal and multimodal with fix dimension, the proposed shows relatively better accuracy and efficiency. The comparison based on the maximum, minimum, average, standard deviation and non-parametric Wilcoxon test of the optimization results by the above algorithms confirmed the outstanding performance of the proposed method. Through the application of the proposed method to the model updating of a pedestrian bridge, all the differences of the first five frequencies between the measured vibration data and finite element model are reduced from approximate 25% to nearly 5%, and the updated dynamic characteristics show great agreement with the practical structure. From the comparison of the responses between updated model and human-induced vibration experiment, most of the response differences are around 10%. The application of the above real structure further verifies that the proposed method is feasible and strongly recommended in optimization issues of practical structures.

Should Hypervascular Incidentalomas Detected on Per-Interventional Cone Beam Computed Tomography during Intra-Arterial Therapies for Hepatocellular Carcinoma Impact the Treatment Plan in Patients Waiting for Liver Transplantation?

Current guidelines do not indicate any comprehensive management of hepatic hypervascular incidentalomas (HVIs) discovered in hepatocellular carcinoma (HCC) patients during intra-arterial therapies (IATs). This study aims to evaluate the prognostic value of HVIs detected on per-interventional cone beam computed tomography (CBCT) during IAT for HCC in patients waiting for liver transplantation (LT). In this retrospective single-institutional study, all liver-transplanted HCC patients between January 2014 and December 2018 who received transarterial chemoembolization (TACE) or radioembolization (TARE) before LT were included. The number of ≥10 mm HCCs diagnosed on contrast-enhanced pre-interventional imaging (PII) was compared with that detected on per-interventional CBCT with a nonparametric Wilcoxon test. The correlation between the presence of an HVI and histopathological criteria associated with poor prognosis (HPP) on liver explants was investigated using the chi-square test. Tumor recurrence (TR) and TR-related mortality were investigated using the chi-square test. Recurrence-free survival (RFS), TR-related survival (TRRS), and overall survival (OS) were assessed according to the presence of HVI using Kaplan-Meier analysis. Among 63 included patients (average age: 59 ± 7 years, H/F = 50/13), 36 presented HVIs on per-interventional CBCT. The overall nodule detection rate of per-interventional CBCT was superior to that of PII (median at 3 [Q1:2, Q3:5] vs. 2 [Q1:1, Q3:3], respectively, p < 0.001). No significant correlation was shown between the presence of HVI and HPP (p = 0.34), TR (p = 0.095), and TR-related mortality (0.22). Kaplan-Meier analysis did not show a significant impact of the presence of HVI on RFS (p = 0.07), TRRS (0.48), or OS (p = 0.14). These results may indicate that the treatment plan during IAT should not be impacted or modified in response to HVI detection.

However, few combined cost-sensitive learning and Stacking to predict financial distress. In this article, a cost-sensitive learning method for FDP, namely cost-sensitive stacking (CSStacking), is put forward. In this work, a two-phase feature selection method is used to select the optimal feature subset. A CSStacking ensemble model is developed with selected features to make a final prediction. The paired T test and non-parametric Wilcoxon test are employed to check the significant differences between CSStacking and benchmark models. An experiment over Chinese listed company dataset is designed to investigate the effectiveness of CSStacking. The experimental results prove that CSStacking can forecast listed companies’ financial distress five years ahead and improves the identification rate of financially distressed companies, highlighting its potential to reduce economic losses caused by misclassifying financially distressed companies. The results of comparing CSStacking with four types of benchmark models show that CSStacking performs significantly better than benchmark models. Furthermore, the findings illustrate that “asset-liability ratio”, “current ratio”, “quick ratio”, and “industry prosperity index” are critical variables in predicting financial distress for Chinese listed companies.
