Abstract
The gas flow distribution inside a blast furnace affects its smelting. Laser surface detection technology can control the gas flow distribution and promote the stable and smooth running of blast furnace by observing and adjusting the surface condition in the blast furnace in real-time. The laser surface inspection technology in blast furnace gas flow control and optimization was introduced, with Masteel 4,000 m3 blast furnace as an example. The results showed that the 30 W high-power laser had good penetration performance and could obtain clear scanning images of the material surface. In the process of strengthening smelting, the laser detection system determined that the central airflow of blast furnace was insufficient, resulting in a decrease in furnace condition stability, and promptly took measures to adjust the angle of the mineral coke fabric equipment and lifting line. After adjusting the material line, the central airflow was properly suppressed and stabilized, the angle of edge platform increased, the airflow developed properly, and two suitable gas flows were formed, which finally stabilized the furnace condition. Meanwhile, the small duct airflow other than the central airflow was found in time through the laser detection system, which provided conditions for operators to take measures to effectively eliminate the duct airflow, thereby avoiding big impacts on the blast furnace operation and technical and economic indexes. Therefore, the laser surface detection technology could effectively judge the gas flow distribution in the furnace, which contributed to timely adjustment of process parameters and optimization of blast furnace operation.

Published: March 2024

Les communs urbains comme concept et pratique sociale représentent une nouvelle logique socio-économique et territoriale en urbanisme durable. Ils prennent des formes différentes et comprennent plusieurs groupes sociaux, ce qui génère une multitude d’idées et de pratiques, parfois nouvelles, parfois en continuité avec le passé. Nous explorons comment les expériences de communs urbains contribuent aux débats dans les études territoriales, en particulier autour des questions de participation citoyenne et de gouvernance territoriale. À travers deux études de cas de communs urbains dans la ville de Bologne en Italie, nous analyserons les conditions structurelles et contextuelles qui ont conduit à leur création ainsi que les dynamiques associatives développées. Nous offrons un aperçu de comment ces projets contribuent au développement territorial participatif en comparant six éléments : l’inclusion et les pratiques démocratiques; les besoins visés et comblés; l’appropriation de l’espace urbain; l’aspect politique; les valeurs et pratiques féministes; et les valeurs et pratiques écologiques.

Cette étude explore les choix des entreprises de transport maritime en matière de réduction des émissions de gaz à effet de serre (GES) sur la Voie maritime du Saint-Laurent. Pour mener cette étude, une approche qualitative a été adoptée. Elle a consisté principalement à la collecte des données à travers des entrevues semi-structurées auprès des entreprises de la Voie maritime du Saint-Laurent. Une analyse thématique a permis de donner un sens aux données collectées. Les résultats montrent que la majorité des choix des entreprises se concentrent sur les mesures d’efficacité énergétique, mais peu sur les sources d’énergie de rechange. De même, ils révèlent que toutes les entreprises sondées ne s’impliquent pas dans la transition énergétique pour réduire leurs émissions de GES.

Pulmonary tuberculosis (TB) is one of the infectious diseases caused by Mycobacterium tuberculosis and is one of the highest causes of morbidity and mortality rates with a low level of treatment outcome. Indonesia is the second country in the world with the largest tuberculosis burden. This study aims to determine the relationship of sociodemographic characteristics with the results of pulmonary tuberculosis therapy at Banyumas Regional Public Hospital for the period 2019-2021. This study used a case-control method. The inclusion criteria in this study were new pulmonary tuberculosis patients at the Banyumas Regional Public Hospital and patients aged ≥18 years, both male and female. Multi-drug resistance (MDR) TB patients and patients with incomplete medical record data were excluded. There were 166 patients enrolled in this study. Data analysis was performed by univariate analysis and bivariate analysis by chi-square test. The results showed that the sociodemographic characteristics were dominated by male patients (57,2%), patients aged <65 years (66,3%), patients weighing <55 kg (53%), not graduating from college (94%), currently working (64,5%), married (68,7%), have health insurance (94%), and close distance (<10 km) to the hospital (53%). The conclusion is that gender ((P=0,028; OR 2,112; 95%Cl(1,129 – 3,951)), age (P=0,014; OR 2,413; 95% Cl (1,242 – 4,689)), body weight (P=0,000; OR 3,306; 95%Cl (1,748 – 6,252)), and distance from the patient's house to the hospital (P=0,020; OR 2,190; 95% CI (1,176 – 4,077)) have a significant relationship with the outcome of pulmonary TB therapy at Banyumas Regional Public Hospital.

Published: March 2024

BACKGROUND AND OBJECTIVE
Inadequate postintubation sedation (PIS) can lead to unplanned extubations, conscious paralysis, and overall unsafe care of patients. From 2018 to 2020, we realized at our hospital that ∼25% of children received sedation in an adequate time frame in the pediatric emergency department, with 2 unplanned dislodgements of the endotracheal tube. Our objective was to reduce time to initiating PIS from a mean of 39 minutes to less than 15 minutes in our pediatric emergency department by September 2021.

METHODS
A multidisciplinary team was formed in March 2020 to develop a key driver diagram and a protocol to standardize PIS. Baseline data were obtained from December 2017 through March 2020. The primary measure was time from intubation to administration of first sedation medication. Plan-do-study-act cycles informed interventions for protocol development, awareness, education, order set development, and PIS checklist. The secondary measure was unplanned extubations and the balancing measure was PIS-related hypotension requiring pressors. An X-bar and S chart were used to analyze data.

RESULTS
Protocol implementation was associated with decrease in mean time to PIS from 39 minutes to 21 minutes. Following educational interventions, order set implementation, and the addition of PIS plan to the intubation checklist, there was a decrease in mean time to PIS to 13 minutes, which was sustained for 9 months without any observed episodes of PIS-related hypotension or unplanned extubations.

CONCLUSIONS
Quality improvement methodology led to a sustained reduction in time to initiation of PIS in a pediatric emergency department.

Asystole induced by electrical stimulation of the left cingulate gyrus
Authors: Leung Howan , Schindler Kasper , Kwan Patrick , Elger Christian 
Published: March 2024

ABSTRACTThe cortical control of the autonomic system may account for the clinical phenomenon of ictal asystole which, in turn, has been speculated to be a potential mechanism for sudden unexpected death in epilepsy (SUDEP). We report an 18‐year‐old patient with frontal lobe epilepsy who had intracranial electrode placement showing bifrontal seizure‐onset. This patient received electrical stimulation to the left cingulate gyrus and developed cardiac asystole within 3 seconds of electrical stimulation. Intracranial monitoring showed epileptiform discharges in the left frontal polar, frontal lateral and interhemispheric electrodes. We suggest that the left cingulate gyrus, as part of the central autonomic network, may mediate bradyarrhythmia through the vagal pathway. There remains the possibility that other brain regions were also involved due to the time lag between asystole and epileptiform discharges, and the lack of intracranial exploration in the mesial temporal and insular regions.[Published with video sequences]
Screen sensitivity in photosensitive children and adolescents: patient‐dependant and stimulus‐dependant factors
Authors: Bruhn Katia , Kronisch Saskia , Waltz Stephan , Stephani Ulrich 
Published: March 2024

ABSTRACTTelevision viewing is the most frequent cause of photogenic attacks in daily life. In the present study, we examined 48 photosensitive children and adolescents to find out: 1) whether hypersynchronous activity is induced less often by viewing a PC monitor than a television screen and 2) whether certain images are more likely to cause hypersynchronous activity than others. All subjects were tested for sensitivity to intermittent photic stimulation (IPS) and to a black and white striped pattern on cards. Additionally, all were subjected to stimuli from four different images (vertical black and white striped pattern, geometric figures, text, and a painting by Max Pechstein – 1913, Italian church), presented on a television screen (with an image regeneration frequency of 50 Hz) and on PC screens (with regeneration frequencies of 48 and 100 Hz). A total of 21 non‐photosensitive, healthy children and adolescents served as controls. Of the 48 photosensitive subjects 13% were also pattern sensitive (cards), and 33% exhibited screen sensitivity. No differences were found between the three monitor types. However, the hypersynchronous reactivity to the four images presented was significantly different, with high contrast vertical striped pattern being the most provocative. Non‐photosensitive subjects did not react to any of the stimuli. The results of the present study show that screen‐dependant factors are less important than image‐dependant factors.

ABSTRACTWe report on a case of frontal lobe epilepsy in an eight‐year‐old girl. Seizure semiology and EEG indicated an epileptogenic zone localized in the mesial frontal structures, without clear‐cut lateralization. MRI showed a lesion in the right cingulate gyrus, initially regarded as a hamartoma. Ictal SPECT did not have a localization value. MR spectroscopy revealed two metabolic abnormalities: one in the area of the MRI lesion and a second contra‐laterally. Invasive monitoring using subdural electrodes covering the convexity and mesial part of the right frontal lobe including mesial strips with bilateral contacts was used. The invasive monitoring failed to localize ictal onset in the right hemisphere; however, electric stimulation induced seizures from electrodes facing the left supplementary sensorimotor area (“through” thefalx cerebri). We re‐implanted the electrodes over the left frontal lobe and the second invasive monitoring clearly localized the ictal onset zone in the left supplementary sensorimotor area, which was subsequently resected. Histopathology found MRI‐negative focal cortical dysplasia. The contralateral lesion was reassessed as nonspecific enlargement of perivascular spaces. The patient has been seizure‐free for more than two years.[Published with video sequences]
Epilepsy in a rural elderly population
Authors: Baran Mona , Stecker Mark M. 
Published: March 2024

ABSTRACT

Purpose
The first goal of this study was to describe the characteristics of elderly patients with epilepsy and the antiepileptic drugs used to treat them. Next, the factors (such as epilepsy type, seizure frequency, medical comorbidities, etc.) influencing antiepileptic drug choice and living situation were explored.

Methods
Retrospective chart review of patients older than 70 with epilepsy seen in a rural health care system. This yielded 449 patients with epilepsy, 54 patients with isolated seizures and 38 patients with syncope as the primary diagnosis.

Results
The most commonly used antiepileptic drug was phenytoin. New generation AED's which had fewer side effects were used much less frequently than old generation AED's but the probability of using new generation AED's was increased in patients with renal failure and congestive heart failure as well as in patients that had seen a neurologist. Patients with acute symptomatic seizures, dementia, chronic obstructive pulmonary disease, frequent seizures and advanced age were less likely to be independent. Patients that had seen a neurologist as an outpatient were more likely to live independently.

Conclusions
The elderly are a vulnerable population because of difficulty communicating their symptoms and their needs. This leads to the suboptimal use of AED's as well as poor outcomes. Careful attention to seizure control and medication side effects is critical in promoting good outcomes in this patient group. This retrospective study suggests that access of elderly patients with epilepsy to specialty care improves outcomes in terms of living status. This important information needs to be confirmed by prospective studies.
