Published: June 2023

Autonomous surgical task execution has the potential to improve surgeons’ working conditions, increase hos- pital throughput, and better patient outcomes in the future. While fully autonomous robotic minimally inva- sive surgery (RMIS) is currently unrealistic for several reasons, partly automated surgery – or task autonomy [1] – is being explored for different surgical tasks. One such task is suturing, which involves complex motions in a challenging environment. Automating the suturing task using surgical robots has been attracting research interest (see, e.g., [2]–[4] for recent studies). Despite these advances, automated suturing is still lim- ited to controlled environments and is not yet applicable in realistic surgical settings. This paper presents a step towards autonomous robotic suturing. Specifically, we propose a method for suture needle state estimation during insertion into soft tissue based on electrical bioimpedance (EBI) sensing. EBI is an advantageous sensing modality in RMIS, given that it is non-invasive and requires only minor modifications to existing surgical instruments. In this study, we equip a surgical robot with EBI sensing capabilities, allowing the robot to measure the electrical impedance between a needle driver instrument and a common ground elec- trode. The proposed method requires a suture needle with insulation coating except for its tip, end, and notch in the middle. We conducted an experiment for concept validation based on ex vivo animal tissue where we obtained a 98.8 % prediction accuracy on four different suture needle insertion states. Most interestingly, we could accurately determine when the needle tip exits after being pushed through soft tissue, which is chal- lenging to do with, e.g., computer vision due to the needle’s small size and occlusions. The needle tip exiting is valuable information as often one wishes to grasp the needle tip with a second manipulator to complete the suture throw by pulling the needle through the tissue.

The development of future surgical therapies has driven the efforts to increase the precision of robot-guided manipulators beyond sub-millimetre accuracies. Medical applications such as reconstructive microsurgery, vitreoretinal eye surgery and cellular level neurosurgery still require achieving precision comparable to the size of human cells [1]. Most commercially available systems can achieve millimetre accuracies with a few examples of higher precision instruments including ophthalmic and reconstructive microsurgery robots achieving accuracies within the range of hundreds of microns [1]. A parallel robot is a closed-loop mechanism where the end-effector is coupled to the base via multiple sequences of links. These devices are mostly used in industrial pick and place applications due their advantages including high precision, stiffness, speed, and low moving inertia [2]. However, a major disadvantage is their limited workspace and rotational capabilities. In the context of cellular level surgical applications, having a reduced workspace does not represent a disadvantage given that, as in most of the cases, the surgical procedure is to be performed within a reduced manipulation volume. This paper presents an integrated methodology outlining the design and testing of a delta robot based on linear actuators achieving micron level end effector positioning accuracy. The main application of the here presented design is to perform superficial tissue optical biopsy with future prospects of being able to conduct cellular level surgeries. The design methodology considers two parameters determining the robot geometry and dimensions these are: the end-effector workspace (~ 5 mm3) and the end-effector motion resolution (1 μm). The robot performance was evaluated using a non-contact metrology approach based on bright field microscopy (BFM) to characterize the precision and kinematic performance. Our results demonstrate that the presented methodology can be used for designing high precision robots achieving accuracies <1 μm.

America’s Occupation of Iraq and its Implications
Authors: Nakdon Tenzin , Ladol Chimat
Published: June 2023

The US-led invasion of Iraq took place on 20 March 2003. The question that arises is what made the US to invade, occupy, destroy and then to reconstruct Iraq state and to what extend the occupation is legitimate? A debate continued throughout the period of the US occupation over Iraq as to the legitimacy of the US invasion. It first started with the WMD and its threat to the world peace. The war that started in 2003 with the motive of removing Saddam with the false claim of Iraq’s possession of WMD has led to death of thousands of people on both the sides. Despite having no evidence, the Bush administration also tried to convince people that Saddam had a hand in 11 September attack and thus started the invasion of Iraq as a part of ‘war on terrorism’. When US failed to find any link between Saddam and al-Qaeda and the 11 September attack, the public support towards the war gradually declined.
Documentation of Surface Soil Characteristics as Indicator of Soil Erosion: A Case of East Khasi Hills in and around Shillong, Meghalaya
Authors: Saha Snehasish , Sarkar Bandana , Das Mantu
Published: June 2023

Soil characteristics are the result of the interaction of pedogenic elements and processes in a specific location. The hilly and mountainous regions are equipped with a diverse set of environmental elements that impact soil spatial variability. This research work is mainly focused on documentation of surface soil characteristics of East Khasi Hills. So many factors are responsible for soil erosion here and dominantly the anthropogenic activities. With the increase of population, changing land use patterns with unscientific manners is one of the ecological phenomena in Meghalayan landscapes. This causes heavy soil erosion especially their agricultural activity such as slash and burn process that makes the land very infertile. Data on surface soil characteristics or surface soil status has been collected from primary field surveys. Base maps were prepared related to this research work with the help of Q-GIS (version 3.6) software and statistical analysis was done using MS Excel 2013 on the basis of both primary and secondary database. Rain induced soil erosion associated with supersaturated soil matrix failure is the major attestation of soil erosion here. Authors mainly have tried to make some inferences towards the correlation of surface soil characteristics and erodibility of the soil.

#EspañaInvadida. Disinformation and hate speech towards refugees on Twitter: A challenge for critical thinking
Authors: Essalhi-Rakrak Abdellah , Pinedo-González Ruth
Published: June 2023

Disinformation is not a new phenomenon, but it is widespread in our society since social media have become a media loudspeaker. The outbreak of war in Ukraine has produced a social debate, partly reflected on social networks, about the treatment of Ukrainian refugees compared with other refugees from the South. For this reason, this research proposes a study that follows a qualitative interpretative methodology with an exploratory and descriptive scope that analyses in depth the content of the discourse on Twitter about refugees and uses computer-mediated discourse analysis as a technique for obtaining data. Specifically, it compares the content published under the hashtags #NotRefugees and #Refugees, and for this purpose, a data analysis has been carried out using Atlas.ti. The results show a differentiated treatment between refugees from the North and the South, as well as a propagation of misinformation through hate speech, in which a favourable and welcoming treatment of Ukrainian refugees is shown, while various types of hate speech towards the rest of the refugees from the South are evident. Hate towards refugees from the South on Twitter is justified on the grounds that they threaten national security, economy, and identity. This phenomenon reflects the urgent need to develop critical and ethical digital competence in the face of disinformation in social networks and media, where the development of critical and ethical thinking is essential.

Published: June 2023

La recherche sur l’intelligence artificielle (IA) appliquée à la médecine d’urgence et son utilisation au quotidien dans les structures d’urgences (SU) ont augmenté significativement ces dernières années. L’IA doit être considérée comme un outil d’aide à la prise en charge diagnostique et thérapeutique des patients et d’amélioration de l’organisation des SU, notamment par la prise en compte de contraintes « métiers », contextuelles, relatives aux patients et plus généralement structurelles. L’IA comporte des avantages (reproductibilité, rapidité) mais aussi des risques (erreur, perte d’esprit critique). À l’image du Règlement général sur la protection des données et notamment de santé, la Commission européenne a publié un projet de règlement nommé « AI Act » pour la conception, le développement et l’utilisation des algorithmes d’IA. Elle souhaite imposer, entre autres, une garantie humaine, autrement dit une supervision humaine pour assurer la sécurité des patients, des soignants et des institutions. La mise en place d’un collège de garantie humaine pluriprofessionnel visant à garantir la supervision des outils d’IA de la conception au développement, au déploiement et à l’utilisation quotidienne permettra ainsi d’assurer durablement la sécurité des patients.
Scolarité des élèves atteints de cancer et rôle des enseignants : une étude exploratoire en Suisse romande
Authors: Diezi M. , Caputo C. Fawer , Naef F.
Published: June 2023

S’il reste rare, un diagnostic de cancer chez un élève a souvent un impact majeur non seulement sur l’enfant malade, sa famille et son entourage, mais également sur sa scolarité. L’absentéisme lié aux traitements, les possibles effets secondaires et les divers troubles cognitifs que la maladie peut engendrer amènent parfois à des décrochages scolaires. Pourtant, une réintégration dans une vie la plus normale possible est souhaitable et participe à la stabilité du jeune. Elle nécessite toutefois la collaboration de multiples intervenants, dont les enseignants qui jouent un rôle essentiel dans ce retour à la normalité. Or, diverses études ont démontré que les enseignants les mieux informés sur le cancer de l’enfant étaient aussi ceux qui prenaient le mieux en compte les besoins de l’élève malade et qui mettaient en place des aménagements scolaires adaptés. Dans notre article, nous exposons les résultats d’une étude exploratoire que nous avons menée en Suisse romande auprès d’enseignants exerçant dans l’école ordinaire et par le biais d’un questionnaire non standardisé, posté dans des réseaux professionnels. L’objectif de cette recherche était d’établir un premier état des lieux en les interrogeant sur les mesures adaptatives mises en place pour leur élève, les collaborations internes et externes à l’école, la gestion de la classe, les difficultés éprouvées et leurs besoins.

Published: June 2023

Technological networks have established a new social morphology of the modern world. The paper provides an understanding of the notion of the networked public sphere by examining all the seminal notions to theorize the ‘Networked Public Sphere’. The paper reflects that the boundaries between old and new media have been blurred and the new media technologies have established a hybrid environment in which there is a huge interplay between conventional media and new media. The paper concludes that the political use of social media among citizens in the networked public sphere helps to devise strategies to be engaged in online and offline political activities and generate a public discourse among them that influence the political domains of the society.

Authors: Mahmood Qasim , Salim Amna , Zulfiqar Amna
Published: June 2023

Ads with adult themes are produced devoid of the consideration that there might children amongst the viewers watching these themes and are being cognized sexually. The current study aims to analyze the issue of sexualization in children of Pakistan through exposure to sexual themes used in TV advertisements. The current research employed dual research methods. In the first stage, qualitative content analysis of television ads was conducted, and in the second stage; focused group interviews were conducted with the children to validate the findings of the first method. The results indicate that children learn and imitate what they watch through TV advertisements. It concludes that exposure of children to such advertisements containing sexual content and themes leads to the adaptation of behavior that is not suitable for the children.

Authors: Yuan Xingyun , Zhao Haojin , Shan Yuanjun , Huang Jiacheng , Hu Jinrong , Yang Jie , Peng Zhouzhou , Kong Weilin , Guo Changwei , Zi Wenjie , Yu Nizhen
Published: June 2023

OBJECTIVE

Authors of this study aimed to evaluate the effects of collateral status on the prognostic value of endovascular treatment (EVT) in patients with basilar artery occlusion (BAO) due to large-artery atherosclerosis (LAA).

METHODS

The study included 312 patients from the BASILAR (Endovascular Treatment for Acute Basilar Artery Occlusion Study) registry who had undergone EVT for acute BAO due to LAA and whose composite collateral scores were available. The effects of collateral status on EVT were assessed based on the composite collateral score (0–2 vs 3–5). The primary outcome was a favorable outcome (modified Rankin Scale score of 0–3) at 90 days.

RESULTS

The composite collateral score was 0–2 in 130 patients and 3–5 in 182. A good collateral status (composite collateral score 3–5) was associated with a favorable outcome (66/182 [36.3%] vs 31/130 [23.8%], adjusted odds ratio [aOR] 2.21, 95% CI 1.18–4.14, p = 0.014). A lower baseline National Institutes of Health Stroke Scale (NIHSS) score was an independent predictor of a favorable outcome in the poor collateral status group (aOR 0.91, 95% CI 0.87–0.96, p = 0.001). In the good collateral status group, there was a significant correlation between favorable outcomes and a younger age (aOR 0.96, 95% CI 0.92–0.99, p = 0.016), lower baseline NIHSS score (aOR 0.89, 95% CI 0.85–0.93, p < 0.001), lower proportion of diabetes mellitus (aOR 0.31, 95% CI 0.13–0.75, p = 0.009), and shorter procedure time (aOR 0.99, 95% CI 0.98–1.00, p = 0.003).

CONCLUSIONS

A good collateral status was a strong prognostic factor after EVT in patients with BAO underlying LAA. A shorter procedure time was associated with favorable outcomes in patients with a good collateral status.
Real-world benefit of intracranial pressure monitoring in the management of severe traumatic brain injury: a propensity score matching analysis using a nationwide inpatient database
Authors: Shibahashi Keita , Ohbe Hiroyuki , Matsui Hiroki , Yasunaga Hideo
Published: June 2023

OBJECTIVE

Intracranial pressure (ICP) monitoring is recommended for the management of severe traumatic brain injury (TBI). The clinical benefit of ICP monitoring remains controversial, however, with randomized controlled trials showing negative results. Therefore, this study investigated the real-world impact of ICP monitoring in managing severe TBI.

METHODS

This observational study used the Japanese Diagnosis Procedure Combination inpatient database, a nationwide inpatient database, from July 1, 2010, to March 31, 2020. The study included patients aged 18 years or older who were admitted to an intensive care or high-dependency unit with a diagnosis of severe TBI. Patients who did not survive or were discharged on admission day were excluded. Between-hospital differences in ICP monitoring were quantified using the median odds ratio (MOR). A one-to-one propensity score matching (PSM) analysis was conducted to compare patients who initiated ICP monitoring on the admission day with those who did not. Outcomes in the matched cohort were compared using mixed-effects linear regression analysis. Linear regression analysis was used to estimate interactions between ICP monitoring and the subgroups.

RESULTS

The analysis included 31,660 eligible patients from 765 hospitals. There was considerable variability in the use of ICP monitoring across hospitals (MOR 6.3, 95% confidence interval [CI] 5.7–7.1), with ICP monitoring used in 2165 patients (6.8%). PSM resulted in 1907 matched pairs with highly balanced covariates. ICP monitoring was associated with significantly lower in-hospital mortality (31.9% vs 39.1%, within-hospital difference −7.2%, 95% CI −10.3% to −4.2%) and longer length of hospital stay (median 35 vs 28 days, within-hospital difference 6.5 days, 95% CI 2.6–10.3). There was no significant difference in the proportion of patients with unfavorable outcomes (Barthel index < 60 or death) at discharge (80.3% vs 77.8%, within-hospital difference 2.1%, 95% CI −0.6% to 5.0%). Subgroup analyses demonstrated a quantitative interaction between ICP monitoring and the Japan Coma Scale (JCS) score for in-hospital mortality, with a greater risk reduction with higher JCS score (p = 0.033).

CONCLUSIONS

ICP monitoring was associated with lower in-hospital mortality in the real-world management of severe TBI. The results suggest that active ICP monitoring is associated with improved outcomes after TBI, while the indication for monitoring might be limited to the most severely ill patients.
The ivy sign as a radiological marker for follow-up of postoperative cerebral perfusion status in adult moyamoya disease

Published: June 2023

OBJECTIVE

Little is known about the relationship between postoperative changes in cerebral perfusion and the ivy sign representing leptomeningeal collateral burden in moyamoya disease (MMD). This study aimed to investigate the usefulness of the ivy sign in evaluating cerebral perfusion status following bypass surgery in patients with adult MMD.

METHODS

Two hundred thirty-three hemispheres in 192 patients with adult MMD undergoing combined bypass between 2010 and 2018 were retrospectively enrolled. The ivy sign was represented as the ivy score on FLAIR MRI in each territory of the anterior, middle, and posterior cerebral arteries. Ivy scores, as well as clinical and hemodynamic states on SPECT, were semiquantitatively compared both preoperatively and at 6 months after surgery.

RESULTS

Clinical status improved at 6 months after surgery (p < 0.01). On average, ivy scores in whole and individual territories were decreased at 6 months (all p values < 0.01). Cerebral blood flow (CBF) postoperatively improved in three individual vascular territories (all p values ≤ 0.03) except for the posterior cerebral artery territory (PCAt), and cerebrovascular reserve (CVR) improved in those areas (all p values ≤ 0.04) except for the PCAt. Postoperative changes in ivy scores and CBF were inversely correlated in all territories (p ≤ 0.02), except for the PCAt. Furthermore, changes in ivy scores and CVR were only correlated in the posterior half of the middle cerebral artery territory (p = 0.01).

CONCLUSIONS

The ivy sign was significantly decreased after bypass surgery, which was well correlated with postoperative hemodynamic improvement in the anterior circulation territories. The ivy sign is believed to be a useful radiological marker for postoperative follow-up of cerebral perfusion status.
Outcomes of endoscopic treatment for early correction of craniosynostosis in children: a 26-year single-center experience
Authors: Domínguez Leonardo , Rivas-Palacios Claudio , Barbosa Mario M. , Escobar Maria Andrea , Puello Florez Elvira , García-Ballestas Ezequiel
Published: June 2023

OBJECTIVE

Surgery is the cornerstone of craniosynostosis treatment. In this study, two widely accepted techniques are described: endoscope-assisted surgery (EAS) and open surgery (OS). The authors compared the perioperative and reconstructive outcomes of EAS and OS in children ≤ 6 months of age treated at the Napoleón Franco Pareja Children’s Hospital (Cartagena, Colombia).

METHODS

According to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement, patients with defined criteria who underwent surgery to correct craniosynostosis between June 1996 and June 2022 were retrospectively enrolled. Demographic data, perioperative outcomes, and follow-up were obtained from their medical records. Student t-tests were used for significance. Cronbach’s α was used to assess agreement between estimated blood loss (EBL). Spearman’s correlation coefficient and the coefficient of determination were used to establish associations between the results of interest, and the odds ratio was used to calculate the risk ratio of blood product transfusion.

RESULTS

A total of 74 patients met the inclusion criteria; 24 (32.4%) belonged to the OS group and 50 (67.6%) to the EAS group. There was a high interobserver agreement quantifying the EBL. The EBL, transfusion of blood products, surgical time, and hospital stay were shorter in the EAS group. Surgical time was positively correlated with EBL. There were no differences between the two groups in the percentage of cranial index correction at 12 months of follow-up.

CONCLUSIONS

Surgical correction of craniosynostosis in children aged ≤ 6 months by EAS was associated with a significant decrease in EBL, transfusion requirements, surgical time, and hospital stay compared with OS. The results of cranial deformity correction in patients with scaphocephaly and acrocephaly were equivalent in both study groups.

Published: June 2023

OBJECTIVE

Lateral lumbar interbody fusion (LLIF) is a workhorse surgical approach for lumbar arthrodesis. There is growing interest in techniques for performing single-position surgery in which LLIF and pedicle screw fixation are performed with the patient in the prone position. Most studies of prone LLIF are of poor quality and without long-term follow-up; therefore, the complication profile related to this novel approach is not well known. The objective of this study was to perform a systematic review and pooled analysis to understand the safety profile of prone LLIF.

METHODS

A systematic review of the literature and a pooled analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All studies reporting prone LLIF were assessed for inclusion. Studies not reporting complication rates were excluded.

RESULTS

Ten studies meeting the inclusion criteria were analyzed. Overall, 286 patients were treated with prone LLIF across these studies, and a mean (SD) of 1.3 (0.2) levels per patient were treated. The 18 intraoperative complications reported included cage subsidence (3.8% [3/78]), anterior longitudinal ligament rupture (2.3% [5/215]), cage repositioning (2.1% [2/95]), segmental artery injury (2.0% [5/244]), aborted prone interbody placement (0.8% [2/244]), and durotomy (0.6% [1/156]). No major vascular or peritoneal injuries were reported. Sixty-eight postoperative complications occurred, including hip flexor weakness (17.8% [21/118]), thigh and groin sensory symptoms (13.3% [31/233]), revision surgery (3.8% [3/78]), wound infection (1.9% [3/156]), psoas hematoma (1.3% [2/156]), and motor neural injury (1.2% [2/166]).

CONCLUSIONS

Single-position LLIF in the prone position appears to be a safe surgical approach with a low complication profile. Longer-term follow-up and prospective studies are needed to better characterize the long-term complication rates related to this approach.

Published: June 2023

OBJECTIVE

The objective of this study was to calibrate an updated predictive model incorporating novel clinical, radiographic, and prophylactic measures to assess the risk of proximal junctional kyphosis (PJK) and failure (PJF).

METHODS

Operative patients with adult spinal deformity (ASD) and baseline and 2-year postoperative data were included. PJK was defined as ≥ 10° in sagittal Cobb angle between the inferior uppermost instrumented vertebra (UIV) endplate and superior endplate of the UIV + 2 vertebrae. PJF was radiographically defined as a proximal junctional sagittal Cobb angle ≥ 15° with the presence of structural failure and/or mechanical instability, or PJK with reoperation. Backstep conditional binary supervised learning models assessed baseline demographic, clinical, and surgical information to predict the occurrence of PJK and PJF. Internal cross validation of the model was performed via a 70%/30% cohort split. Conditional inference tree analysis determined thresholds at an alpha level of 0.05.

RESULTS

Seven hundred seventy-nine patients with ASD (mean 59.87 ± 14.24 years, 78% female, mean BMI 27.78 ± 6.02 kg/m2, mean Charlson Comorbidity Index 1.74 ± 1.71) were included. PJK developed in 50.2% of patients, and 10.5% developed PJF by their last recorded visit. The six most significant demographic, radiographic, surgical, and postoperative predictors of PJK/PJF were baseline age ≥ 74 years, baseline sagittal age-adjusted score (SAAS) T1 pelvic angle modifier > 1, baseline SAAS pelvic tilt modifier > 0, levels fused > 10, nonuse of prophylaxis measures, and 6-week SAAS pelvic incidence minus lumbar lordosis modifier > 1 (all p < 0.015). Overall, the model was deemed significant (p < 0.001), and internally validated receiver operating characteristic analysis returned an area under the curve of 0.923, indicating robust model fit.

CONCLUSIONS

PJK and PJF remain critical concerns in ASD surgery, and efforts to reduce the occurrence of PJK and PJF have resulted in the development of novel prophylactic techniques and enhanced clinical and radiographic selection criteria. This study demonstrates a validated model incorporating such techniques that may allow for the prediction of clinically significant PJK and PJF, and thus assist in optimizing patient selection, enhancing intraoperative decision making, and reducing postoperative complications in ASD surgery.
Outcomes and reoperation rates of adult spinal deformity patients with baseline sagittal malalignment based on the cranial axis to the hip at 2 years postoperatively

Published: June 2023

OBJECTIVE

The aim of this study was to discern whether patients with a cranial sagittal vertical axis to the hip (CrSVA-H) > 2 cm at 2 years postoperatively exhibit significantly worse patient-reported outcomes (PROs) and clinical outcomes compared with patients with CrSVA-H < 2 cm.

METHODS

This was a retrospective, 1:1 propensity score–matched (PSM) study of patients who underwent posterior spinal fusion for adult spinal deformity. All patients had a baseline sagittal imbalance of CrSVA-H > 30 mm. Two-year patient-reported and clinical outcomes were assessed in unmatched and PSM cohorts, including Scoliosis Research Society–22r (SRS-22r) and Oswestry Disability Index scores as well as reoperation rates. The study compared two cohorts based on 2-year alignment: CrSVA-H < 20 mm (aligned cohort) vs CrSVA-H > 20 mm (malaligned cohort). For the matched cohorts, binary outcome comparisons were carried out using the McNemar test, while continuous outcomes used the Wilcoxon rank-sum test. For unmatched cohorts, categorical variables were compared using chi-square/Fisher’s tests, while continuous outcomes were compared using Welch’s t-test.

RESULTS

A total of 156 patients with mean age of 63.7 (SEM 1.09) years underwent posterior spinal fusion spanning a mean of 13.5 (0.32) levels. At baseline, the mean pelvic incidence minus lumbar lordosis mismatch was 19.1° (2.01°), the T1 pelvic angle was 26.6° (1.20°), and the CrSVA-H was 74.9 (4.33) mm. The mean CrSVA-H improved from 74.9 mm to 29.2 mm (p < 0.0001). At the 2-year follow-up, 129 (78%) of 164 patients achieved CrSVA-H < 2 cm (aligned cohort). Patients who had CrSVA-H > 2 cm (malaligned cohort) at the 2-year follow-up had worse preoperative CrSVA-H (p < 0.0001). After performing PSM, 27 matched pairs were generated. In the PSM cohort, the aligned and malaligned cohorts demonstrated comparable preoperative patient-reported outcomes (PROs). However, at the 2-year postoperative follow-up, the malaligned cohort reported worse outcomes in SRS-22r function (p = 0.0275), pain (p = 0.0012), and mean total score (p = 0.0109). Moreover, when patients were stratified based on their magnitude of improvement in CrSVA-H (< 50% vs > 50%), patients with > 50% improvement in CrSVA-H had superior outcomes in SRS-22r function (p = 0.0336), pain (p = 0.0446), and mean total score (p = 0.0416). Finally, patients in the malaligned cohort had a higher 2-year reoperation rate (22% vs 7%; p = 0.0412) compared with patients in the aligned cohort.

CONCLUSIONS

Among patients who present with forward sagittal imbalance (CrSVA-H > 30 mm), patients with CrSVA-H exceeding 20 mm at the 2-year postoperative follow-up have inferior PROs and higher reoperation rates.

Selain gandum dan padi, jagung (zea mays) adalah salah satu tanaman pangan yang memiliki kandungan karbohidrat. Kulit jagung dan tongkol jagung merupakan limbah padat dari hasil pengolahan jagung. Peningkatan nilai ekonomis dari kulit jagung yaitu dengan manfaatkan kulit jagung tersebut sebagai adsorben. Pada kulit jagung terdapat kandungan selulosa 41% dan hemiselulosa 36%. Pada Penelitian ini bertujuan untuk mengetahui proses pembuatan adsorben berjenis karbon aktif  dan efektifitas karbon aktif kulit jagung untuk mengelola air sungai terhadap kadar COD, TSS, dan TDS. Tiga proses utama dalam pembuatan karbon aktif ini yaitu proses dehidrasi, karbonisasi, dan aktivasi. Aktivasi karbon aktif menggunakan H2O2 1 M, dengan kondisi operasi 500°C durasi 30 menit. Karbon aktif kemudian diuji dengan sample air sungai menggunakan variasi sebanyak 0 g; 1 g; 2 g ;3 g; 4 g; 5 g dan waktu kontak perendaman 24 jam. Variasi massa karbon aktif 4 gr merupakan hasil optimal yang didapatkan. Penurunan yang mampu dihasilkan dari pengujian air sungai tersebut adalah COD sebesar 12,8 mg/l ; TSS 10 mg/l ; TDS 120 mg/l  daripada tanpa menggunakan adsorben COD sebesar 25,6 mg/l ; TSS 19 mg/l ; TDS  200 mg/l . Karbon aktif yang dibuat dari kulit jagung ini efektif digunakan pada pengolahan air sungai dibuktikan dengan adanya penurunan nilai COD,TSS dan TDS.

Abstract: Line planning is the transportation service's fundamental, which directly affects the subsequent operation plans. It is better to focus on the operational profit when considering the market competition for transportation operation plans. This paper aims to maximize the operational profit when optimizing the high-speed railway network line plan by constructing a mixed integer nonlinear programming model. The model integrates line planning and passenger route choice behaviors. An adaptive simulated annealing algorithm with neighborhood search is applied based on a given line pool. A heuristic passenger assignment method is developed to ensure a high level of passenger satisfaction. The proposed model and algorithm are experimentally evaluated. The instance results show that the operational profit and capacity utilization can be significantly improved. Compared with the designed greedy heuristic algorithm, the proposed algorithm performs better in operational profit improvement and has high efficiency.

Paroki Santa Maria diangkat Ke Surga Eban merupakan salah satu Paroki yang diresmikan pada tanggal 23 Maret 1952 oleh Vikariat Apostolik Atambua-Timor. Paroki ini terletak di Miomaffo Barat, Kabupaten Timor Tengah Utara-Provinsi Nusa Tenggara Timur dengan jumlah umat berkisar 12.000 jiwa yang tersebar pada 23 lingkungan. Aktivitas kegiatan pelayanan yang diberikan oleh Pastor Paroki dicatat dan disimpan oleh Sekretariat Paroki dengan cara sebagian manual dan sebagian menggunakan aplikasi komputer. Sistem pengolahan data yang digunakan belum memiliki database yang tersimpan dalam sebuah komputer sehingga bila gereja atau umat membutuhkan suatu informasi maka setiap file yang ada harus diperiksa satu per satu untuk memperoleh data yang dibutuhkan. Sehingga akan memakan waktu yang lama dalam proses pencarian. Berdasarkan permasalahan tersebut, maka dibutuhkan Sistem Informasi Administrasi Paroki (SIAP) yang berbasis website sehingga dapat memberikan pelayanan yang lebih baik dalam penyampaian informasi yang ada. SIAP diharapkan dapat mengelola data administrasi seperti pendaftaran Pelayanan Sakramen. Sakramen yang dilayani berupa Sakramen Baptis, Komuni Pertama, Sakramen Krisma dan Sakramen Perkawinan. Pengembangan SIAP menggunakan model pengembangan sistem Incremental. Alasan digunakan metode ini karena metode ini dianggap mampu mengamodasikan perubahan secara fleksibel dan memiliki resiko yang lebih rendah terhadap proses pengembangan sistem.
ENKRIPSI SMS DENGAN MENGGUNAKAN MODE CIPHER FEEDBACK (CFB) 8-BIT BERBASIS ANDROID
Authors: Widiana Siska Ayu , Iqbal Firdaus
Published: June 2023

Tujuan dari penelitian ini adalah untuk mengurangi faktor-faktor yang mengancam keamanan isi pesan dengan menggunakan aplikasi enkripsi SMS dengan menggunakan mode cipher feedback 8-bit pada aplikasi android. Faktor pertama, yaitu faktor fisik adalah jika telepon selular dipegang oleh orang lain maka orang tersebut dapat membaca dan mendapatkan informasi dari pesan di dalam telepon selular. Faktor kedua adalah keamanan pesan di dalam sistem, penyebabnya karena operator selular hanya mengenkripsi pesan pada saat proses transmisi, sedangkan dalam proses penyimpanan pesan di operator selular berbentuk plainteks. Tahapan proses pada mode cipher feedback 8-bit dimulai dengan menginput SMS yang akan dikirimkan, yaitu berupa plainteks dan ditambah dengan menginput initialization vector (IV) dan kunci yang di proses melalui fungsi enkripsi menggunakan algoritma AES 128 untuk menghasilkan keystream. 8 bit awal hasil dari keystream ini lalu di exclusive or (XOR) kan dengan 8 bit awal plainteks dan  hasil yang didapat akan dikembalikan lagi ke blok paling kiri dari IV awal dengan proses register geser, dan begitu pun selanjutnya sampai dihasilkan sebuah pesan yang berbentuk cipherteks yang berbentuk deretan heksadesimal. Hasil cipherteks tersebut lah yang akan dikirimkan kepada penerima pesan melalui server sehingga pesan asli yang ditujukan kepada penerima dapat dijaga kerahasiaannya. Sesuai dengan hasil diatas maka dapat disimpulkan bahwa isi pesan yang dikirimkan tidak akan bisa dibaca kecuali oleh pengirim dan penerima saja.
