Quality Ecoprint Results of Teak Flowers and Leaves (Tectona Grandis) on Blacu and Tencel Fabrics with Tingi Natural Dyes
Authors: Wahyuningsih S E , Atika  , Putri N A R 
Published: August 2024

Abstract
The results of the descriptive analysis show that on the calico fabric, the color direction of the teak flower motif leads to a yellow-orange color with the name putty, and the teak leaf motif leads to a gray-red color with the name light wood. Then on the calico fabric, the results were reviewed from the aspect of color fastness to washing the ecoprint flower and teak leaf motif soap, obtaining an average value of 4.50 with good criteria. On the tencel, the teak flower motif leads to a gray-yellow color with the name New Orleans, and the teak leaf motif leads to a gray-red color with the name bazaar. The conclusion of the study is that the quality of the ecoprint motifs of teak flowers and leaves on calico and tencel fabrics has a gray-yellow-red color direction with the result that the color fastness to soap washing is 4-4.5 with good criteria. The suggestion from this study is that you can make a teak leaf ecoprint motif on tencel fabric properly so that the fastness obtained is the same as the teak flower ecoprint motif, one of which is by increasing the fixation with alum mordant so that the solution absorbs more into the fabric.

Published: August 2024

Abstract
The periodic bridge maintenance is very prominent to be done to ascertain the actual condition of the structure. With the result that it can be ensured that the bridge structure can provide comfortable and safe services. Another objective that can be obtained is that the bridge structure can reach the service life as planned. To discover the condition of the bridge can be done visually or by using certain sensors which are now widely used. This study will discuss the identification of modal frequency at single-span pre-stressed concrete girder bridges using the peak picking method. Modal frequency as part of the dynamic properties of a structure will be used to find out the current and future condition of the structure. The first step is to collect vibration data using a velocity meter. The next stage is to analyze field data using the peak picking method to obtain frequency capital. From the field data analysis, it was found that the vibration frequency is 3.163 Hz as the fundamental frequency of the Kalipancur bridge structure, Semarang. Frequency data equipped with updated finite element model can be used to monitor the condition of the bridge structure in the future.

Published: August 2024

Abstract
The multi-criteria crow search algorithm proposed in this paper is a novel optimization method designed to address the control and stability challenges faced by bicopter systems. Bicopters, unmanned aerial vehicles with two rotors to use energy more efficiently, require precise control to maintain balance and maneuverability. This optimization approach leverages the Crow Search Algorithm (CSA) and aims to achieve a balanced control system for bicopters while considering multiple objectives simultaneously. The key goal of this approach is to optimize the PI control parameters employed in the bicopter system to enhance stability and maneuverability, represented by settling time and overshoot in transient response. Through a combination of exploration and exploitation, the algorithm searches for an optimal set of control parameters that satisfies these criteria, striking a better control system that can benefit from improved stability and maneuverability. As shown from the experiment, this algorithm offers a promising avenue for designing control strategies that address the inherent challenges of bicopter systems, especially after being compared to the existing approaches.
Evaluation of Road Functional Performance Using Pavement Condition Index (PCI) and International Roughness Index (IRI) Methods Using Hawkeye (Case Study: Demak Ring Road, Central Java Province)
Authors: Kartika Novianti P , Setyawan Ary , Pramesti F Pungky 
Published: August 2024

Abstract
The condition of the road pavement can be judged from the functional performance by measuring the surface condition of the pavement and the value of surface roughness. Pavement surface condition measurements are usually carried out using the Pavement Condition Index (PCI) survey method. While the measurement of surface roughness values is usually carried out with the Roughness survey method so that the International Roughness Index (IRI) is obtained. This study tries to evaluate the value of a pavement condition by reviewing functional performance to identify the value of the pavement condition. Checking road conditions in this study was carried out using two survey methods, namely the International Roughness Index (IRI) method, the Pavement Condition Index (PCI) method. The results of the examination are analyzed so that the correlation between each method can be known. The results of the study explained that based on the results of observations of the functional condition of road pavements with the Pavement Condition Index (PCI) method using the Hawkeye 2000 tool on the Demak Ring Road section, a PCI value of 65.34 was obtained with the “Fair” category, the functional condition of the road pavement with the International Roughness Index (IRI) method of the Hawkeye 2000 tool on the Demak Ring Road section obtained a IRI value of 6.60 with the category “Medium”, and the correlation of the functional condition of road work using the Pavement Condition Index (PCI) method with the International Roughness Index (IRI) on the Demak Ring Road section has no correlation.
Regional Typology in Central Java: Urban and Rural Relation based on Cluster Analysis
Authors: Rahadini A 
Published: August 2024

Abstract
Urbanization and industrialization are an initial indication of the growth and expansion of urban areas to rural area. This article provides an overview of rural-urban transformation in Central Java based on population, economic and socio-politic variables. This study is part of research about regional disparity in Central Java. The aim of the study is to observe the regional typology in Central Java in two different period. The analysis departs form the concept of growth pole. The concept argues that the development of cities as the urban area is expected naturally spread to the hinterland or rural areas. Urban area is the center of regional growth process. Rural-urban transformation is designated by the decrease of agricultural sector and the increase of population in some rural region. Industrialization is referred to the transition from agriculture to manufacturing and has been assumed as progress or modernization. Cluster analysis is a multivariate statistical method for classifying objects according to their related qualities. This clustering was applied to perform the most likely cluster in Central Java using several variables at once. This study uses data from 2010 and 2020 to compare the evolution of typology. However, during the pandemic period in 2020, even most region occurred negative growth, the urban interconnectivity was established as before. The result displays in two clusters solution. Both clusters describe that the typology was established from two different methods. The first method is described as urban growth process which the industrialization comes from higher region to its surroundings (Semarang-Surakarta) and it generates corridor pattern. The second method could be interpreted as the growth process coming from the lower region (e.g., Kudus and Cilacap), where change may occur distant from the urban area.

Abstract
Tensor networks (TNs) have seen an increase in applications in recent years. While they were originally developed to model many-body quantum systems, their usage has expanded into the field of machine learning. This work adds to the growing range of applications by focusing on planning by combining the generative modeling capabilities of matrix product states and the action selection algorithm provided by active inference. Their ability to deal with the curse of dimensionality, to represent probability distributions, and to dynamically discover hidden variables make matrix product states specifically an interesting choice to use as the generative model in active inference, which relies on ‘beliefs’ about hidden states within an environment. We evaluate our method on the T-maze and Frozen Lake environments, and show that the TN-based agent acts Bayes optimally as expected under active inference.
synphage: a pipeline for phage genome synteny graphics focused on gene conservation
Authors: Grosboillot Virginie , Dragoš Anna 
Published: August 2024

Abstract

Motivation
Visualization and comparison of genome maps of bacteriophages can be very effective, but none of the tools available on the market allow visualization of gene conservation between multiple sequences at a glance. In addition, most bioinformatic tools running locally are command line only, making them hard to setup, debug, and monitor.

Results
To address these motivations, we developed synphage, an easy-to-use and intuitive tool to generate synteny diagrams from GenBank files. This software has a user-friendly interface and uses metadata to monitor the progress and success of the data transformation process. The output plot features colour-coded genes according to their degree of conservation among the group of displayed sequences. The strength of synphage lies also in its modularity and the ability to generate multiple plots with different configurations without having to re-process all the data. In conclusion, synphage reduces the bioinformatic workload of users and allows them to focus on analysis, the most impactful area of their work.

Availability and implementation
The synphage tool is implemented in the Python language and is available from the GitHub repository at https://github.com/vestalisvirginis/synphage. This software is released under an Apache-2.0 licence. A PyPI synphage package is available at https://pypi.org/project/synphage/ and a containerized version is available at https://hub.docker.com/r/vestalisvirginis/synphage. Contributions to the software are welcome whether it is reporting a bug or proposing new features and the contribution guidelines are available at https://github.com/vestalisvirginis/synphage/blob/main/CONTRIBUTING.md.
357 An Audit of Quality of Discharge Summaries in Cardiac Surgery
Authors: Sogandji N , Ali J 
Published: August 2024

Abstract

Aim
We performed a single-centre closed loop audit assessing the completeness and quality of e-discharge summaries following cardiac surgery against local standards.

Method
The e-discharge summaries of patients who underwent cardiac surgery form 1/08/2023 to 10/08/2023 were audited against the standards set by the local hospital’s e-discharge summary template. Results and recommendations were shared at a team meeting of the hospital, and on a poster displayed in the MDT office. The same data was then collected for patients who underwent cardiac surgery from 25/10/2023 to 6/11/2023.

Results
110 patients were included across 2 cycles. Of 16 domains of interest, 5 were complete in 100% of e-discharge summaries in the first cycle, increasing to 7 in the second. The proportion of summaries with the ‘reason for admission’ misplaced in the clinical summary instead of the allocated field decreased from 43% to 40%, while proportion of GP requests with the reasoning in the allocated box rose from 55% to 57%.For those with no requests to the GP, this was initially specified in the mandatory field as N/A or equivalent in 23% rising to 48% in cycle two, whereas for those who had no ECHOs during the admission, this was specified in 20% initially, rising to 27%. The proportion avoiding acronym use decreased from 17% to 15%.

Conclusions
Even though compliance improved between the two cycles, the standard of 100% was not met for most criteria. Further team education and revision of the template itself is required to allow information reporting in a succinct, user-friendly format.

Authors: Mak R , Lee W T , Carney A , Olaifa F , Islam M , Smith T , Strachan D , Elseed A , Hard R 
Published: August 2024

Abstract

Aim
The COVID-19 pandemic has increased the number of emergency laparoscopic cholecystectomies due to elective surgery cancellations. However, the impact of COVID-19 on the timing of surgery remains unclear. The Association of Upper Gastrointestinal Surgery (AUGIS) advised to perform an emergency laparoscopic cholecystectomy within 72 hours of diagnosing acute cholecystitis. This audit aims to evaluate the impact of the post-COVID-19 period on the timing of emergency laparoscopic cholecystectomies.

Method
A retrospective analysis of patients who underwent an emergency laparoscopic cholecystectomy, in the post-pandemic period, between January and December 2022 was conducted. Primary outcomes include admission to imaging time, admission to theatre time, length of hospital stay, intra- and post-operative complications. Outcomes were audited against AUGIS guidelines and compared with previous audit cycles during the pre-pandemic (2019) and pandemic (2021) periods.

Results
In 2022, 411 patients underwent an emergency laparoscopic cholecystectomy. Median admission to imaging time was 11 hours (IQR 4.6-21.9). Median admission to theatre time was 70.7 hours (IQR 48.4-107.7), compared to 106.5 hours in 2019 and 76.7 hours in 2021. Median length of hospital stay was 5.6 days (IQR 4.0-8.1), compared to 7.5 days in 2019 and 5.3 days in 2021. There were 38 (9.2%) subtotal cholecystectomies, 112 (27.3%) on-table cholangiograms, and 57 (13.9%) CBD explorations performed. 61(14.8%) patients had post-op complications including 9 (2.2%) bile leaks, 5 (1.2%) retained stones, and 7(1.7%) collections.

Conclusions
Timings to emergency laparoscopic cholecystectomies continue to improve in the post-COVID-19 period and is consistent with AUGIS recommendations.
1160 Surgical Harmony: Optimising Referrals for General Surgical Excellence
Authors: Ravichandran S , Kumar A 
Published: August 2024

Abstract

Aim
The appropriateness of referrals is a crucial aspect of patient care. Emergency Departments often struggle to cope with increased patient attendance, and this led to the introduction of a 4-hour waiting time target. Inappropriate referrals can lead to delays in treatment, unnecessary procedures, and increased healthcare costs. The aim is to establish referral guidelines and include criteria for determining when a referral is necessary, documentation requirements, and communication and imaging protocols between the referral provider and the department.

Method
The study was conducted over 2 weeks in July 2020 during the Covid pandemic. The study included all patients referred from the ED to the General surgery department. It included both adult and paediatric patients.

Results
In this study, 78.37 % of referrals were appropriate. But 21.62 % of referrals were inappropriate. Of all the 111 referrals made, 24 patients were inappropriately referred to surgery. They were then referred to other specialities or sometimes treated by General surgery and sent home. Of these, 5 patients didn't have blood results, and 5 other patients were discharged without imaging to prove appropriateness. 19 patients had CT scans and were found to have no surgical pathology.

Conclusions
Routine use of CT scans for surgical abdomen may ameliorate inappropriate ED referrals and improve patient safety and care. Establishing guidelines to streamline when to send them to the acute abdomen pathway, educating healthcare providers, and providing feedback can help reduce inappropriate referrals, improve overall patient outcomes, and reduce the burden on the speciality and Emergency departments.

Published: August 2024

Abstract

Background/Aim
Performing breast reconstruction in large and ptotic breasts remains technically challenging with a high incidence of unsatisfactory cosmetic result and post-operative complications. In this study, we report the experience of Alexandria Main University Hospital (AMUH) in Egypt with skin reducing mastectomy (SRM) with direct to implant breast reconstruction without the use of acellular dermal matrix (ADM) or synthetic meshes.

Method
A prospective study was conducted in AMUH from October 2020 till October 2022. It included twenty female patients, indicated for mastectomy and having large and ptotic breasts, excluding non-motivated patients, inflammatory breast cancer, significant clinical comorbidities as well as patients indicated for adjuvant radiotherapy. All the operations were performed as a single stage in which the SRM was done by wise pattern skin incision with creation of a dermal sling to cover the implant without the use of ADM or synthetic mesh.

Results
The implant was inserted prepectoral, under the dermal sling in 10 cases. In the remaining 10 cases, implant was inserted partially subpectoral by detaching the lower part of pectoralis major from the chest wall and suturing it to the dermal sling. The most frequent complications were delayed healing of T-junction. None of the cases experienced infection, capsular contracture, or implant loss.

Conclusions
SRM and direct to implant breast reconstruction can be safely used in patients with large and ptotic breasts. The inferior dermal sling can be used to cover the implants; thus, it allows for a-single stage breast reconstruction without the need for ADM or synthetic meshes.

Authors: Shirke M , Badran A , Elghazouli Y , Tawil M , Harky A , Ohri S 
Published: August 2024

Abstract

Aim
A thoracic aortic aneurysm (TAA) is a diseased expansion of the thoracic aorta. There is morbidity associated with a dilated aorta, as well as significant mortality. Open thoracic surgery is the fundamental management for proximal lesions, offering definitive treatment with excellent results. This study aimed to summarize preoperative data and operative outcomes of patients who underwent TAA repair at our institution.

Method
Data were retrospectively collected from 234 patients who underwent elective open thoracic surgery at University Hospital Southampton for TAA disease, between 2015 and 2019. Demographics, clinical factors, surgical details, as well as outcome measures, were gathered.

Results
There were 166 males and 68 females, with an overall mean age of 66 years. The breakdown of operations comprised 105 aortic roots, 171 ascending aorta, 20 aortic arch, and 12 descending aorta cases. Mortality was associated with female gender, aortic root surgery, and prosthetic valves. Mean aortic diameters at the time of surgery for the non-genetic aortopathy and genetic aortopathy groups were respectively 4.93cm and 4.63cm in the aortic root, 5.56cm and 4.88cm in the ascending aorta, 5.08cm and 3.87cm in the aortic arch, and 6.63cm and 5.50cm in the descending aorta.

Conclusions
Several factors are associated with complications and morbidity, which should be considered when discussing the risks of intervention with patients. There were no neuroprotective strategies that altered post-operative neurological function. Current practice in our unit fits in with current international guidance.
164 Auto-Amputation of Prostate After Prostate Artery Embolisation for Benign Prostatic Hyperplasia
Authors: Patel P , Hanna G , Mahesan T 
Published: August 2024

Abstract
Prostate Artery Embolisation (PAE) is a treatment modality for Benign Prostatic Hyperplasia (BPH) which is considered to be effective with a low complication rate. It is used as an alternative to Transurethral Resection of the Prostate (TURP), for example, if the prostate is very enlarged or if the patient is unsuitable for general anaesthesia. This case study looks into an 84-year-old male who underwent PAE for Benign Prostatic Hyperplasia. The unusual complication of auto-amputation of the prostate which was found to be in the form of ‘a large (more than 10cm) sloughed tissue’ within the bladder. This finding was made 1 year post procedure with patient presenting with lower urinary tract symptoms, dysuria and ongoing haematuria, requiring multiple blood transfusions. Laser Cystolitholapaxy was initially done followed by Morcellation + completion TURP.
Given that this procedure is done by an Interventional Radiologist, it is important to raise awareness of it occurring and to ensure there is a standardized follow up plan available for these patients. Evidence shows TURP remains the more effective method over PAE in terms of symptom improvement. Therefore, it is important to find patients suitable for PAE by working with the Interventional Radiologists.
