Training Program Analysis for Incidents in Hydrogen Refueling Stations

As the number of hydrogen refueling stations has increased rapidly in recent times, evaluating their incident training programs for first responders, has gained importance. In this study, the Delphi method was used for investigating the training programs, and the importance of the consensus programs was analyzed using the analytical hierarchy process (AHP). Location and operating methods of the emergency shutdown devices, safety distance, and response procedures depending on the hydrogen refueling station and hydrogen vehicle, were deduced. The results reveal that the training regarding emergency shutdown devices is the most important, followed by the one regarding safety distance. Quantitative analysis with regard to the training programs for hydrogen refueling stations can improve the response capability of first responders.

Radiographic evaluation of the congruency of the first metatarsophalangeal joint in hallux valgus

Background The congruency of the first metatarsophalangeal (MTP) joint was extremely important for the selection of operating methods and prognosis, while its radiographic evaluation method was relatively lacking. The purpose of this article was to explore the radiographic indicators for evaluating the congruency of the first MTP joint. Methods The patients who had X-ray of weightbearing in the outpatient system were selected, excluding patients with trauma, deformity, and history of operation. 183 patients with 245 feet were included. The hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), metatarsophalangeal joint angle (MTPJA), congruency index (CI) and tibial sesamoid position (TSP) were measured and do statistical analysis. Results The higher the degree of hallux valgus, the higher the proportion of incongruency of the first MTP joint. Significant differences were found in DMAA, MTPJA and CI between the congruency and incongruency groups of patients with moderate to severe hallux valgus (P < 0.05). The area under curve (AUC) of the receiver operating characteristic(ROC) curve for MTPJA and CI was 0.906 and 0.884, the sensitivity and specificity reached 0.791 and 0.862, 0.949 and 0.644, and the critical values were 10.67 and 0.765 respectively. The correlation test indicated that in the congruency group, DMAA and HVA had positive correlation, but MTPJA, CI and HVA had low correlation coefficients. DMAA and HVA were not correlated in the incongruency group, while MTPJA and HVA were significantly positively correlated, and CI and HVA showed a negative correlation (P < 0.05). Conclusion MTPJA and CI are indicators that can quantitatively evaluate the congruency of the first MTP joint, taking 10° and 0.765 as the demarcation points respectively. Clinically, the congruency of MTP joint should be considered when choosing operating methods for different degrees of hallux valgus, MTPJA and CI can be used as quantitative evaluation indicators.

Development of a Lab-Scale Prototype for Validating an Innovative Pitting Method of Oil Olives

In olive oil extraction processes, different operating methods used for the preparation of olive pastes significantly affect their rheological characteristics, as well as the extraction yields and qualitative characteristics of the oils. To enhance and improve the characteristics of high-quality EVOOs (Extra Virgin Olive Oils), milling technologies have implemented olive pitting in the preparation of olive pastes to be processed for olive oil extraction. Commonly used pitting machines employ the percussion and centrifugal projection of drupes, which often involve the heating of pastes, breaking of kernels, and emulsion of oils. Aiming to improve olive oil pitting processes, the CREA Research Centre for Engineering and Agri-food Processing in Treviglio, Italy, has conceived an alternative method, which is based on the low-speed constriction and mutual abrasion of drupes inside a rotative working chamber. This paper describes the process that led to the hypothesis of an innovative pitting method and to the validation of the hypothesis through the development of a lab-scale pitter prototype. The development steps and the assessment of the results of the prototype trials are reported.

Demand Side Management Studies on Distributed Energy Resources: A Survey

The number of distributed environmentally friendly energy sources and generators necessitates new operating methods and a power network board to preserve or even increase the efficiency and quality of the power supply. Similarly, the growth of matriculates promotes the formation of new institutional systems, in which power and power exchanges become increasingly essential. Because of how an inactive entity traditionally organizes distribution systems, the DG’s connection inevitably changes the system’s qualifications to which it is connected. As a consequence of the Distributed Generation, this presumption is currently legal and non-existent. This article glides on demand side management and analysis on distributed energy resources. Investigation of DSM along with zonal wise classification has been carried out in this survey. Its merits and applications are also presented.

Adult Pulmonary Intensive and Intermediate Care Units: The Italian Thoracic Society (ITS-AIPO) Position Paper

The imbalance between the prevalence of patients with acute respiratory failure (ARF) and acute-on-chronic respiratory failure and the number of intensive care unit (ICU) beds requires new solutions. The increasing use of non-invasive respiratory tools to support patients at earlier stages of ARF and the increased expertise of non-ICU clinicians in other types of supportive care have led to the development of adult pulmonary intensive care units (PICUs) and pulmonary intermediate care units (PIMCUs). As in other European countries, Italian PICUs and PIMCUs provide an intermediate level of care as the setting designed for managing ARF patients without severe non-pulmonary dysfunction. The PICUs and PIMCUs may also act as step-down units for weaning patients from prolonged mechanical ventilation and for discharging patients still requiring ventilatory support at home. These units may play an important role in the on-going coronavirus disease 2019 pandemic. This position paper promoted by the Italian Thoracic Society (ITS-AIPO) describes the models, facilities, staff, equipment, and operating methods of PICUs and PIMCUs.

The Fixated Threat Assessment Centers

Fixated threat assessment centers (FTACs) have been established in the United Kingdom, Australia, and New Zealand. The model was developed to assess and manage risk from isolated loners who write concerning communications or make problematic approaches to politicians or the British royal family. It has recently been expanded to encompass risks of lone actor grievance-fueled violence more broadly. The essential feature of FTACs is that they are police units jointly staffed by police officers and psychiatric staff from the health service. Given the central role that mental state and motivation play in the assessment of risk, the presence of psychiatric personnel greatly enhances the power of risk assessment and catalyzes multiagency interventions with fixated loners, a population with high psychiatric morbidity. This chapter describes the function, structure, and operating methods of FTACs. The FTACs deal with forms of psychotic pathology rarely seen in psychiatric services, but well described by 19th-century phenomenologists.

Detection of Movement Intention for Operating Methods of Serious Games

In many post-stroke cases, patients show dysfunctions in movement, cognition, sense, and language, depending on the damaged area of the brain. Active and repetitive physical rehabilitation centered on the stroke-affected side is essential for effective and rapid neurological recovery of upper extremity dysfunction due to hemiplegia. A symmetric upper extremity trainer is utilized to assist the patient body, depending upon the degree of hemiplegia. In this study, we developed a novel balance handle as a symmetric upper extremity trainer capable of extension, flexion, pronation, and supination of the upper extremity. We collected the surface electromyogram (sEMG) signal data while the subjects were playing a serious game and recorded the electroencephalogram (EEG) signal data while the subjects were performing basic movements with the balance handle, to analyze the effectiveness of the device as an assistive tool for rehabilitation. The triceps brachii were activated during the extension movements, whereas the biceps brachii and deltoid muscles were activated during the flexion movements. With the balance handle, the peak event-related desynchronization (ERD) values were relatively lower while showing higher peak event-related synchronization (ERS) values compared to other types of operating methods, such as hand gripping and gamepad operation. Movement intention of tilting the balance handle for the α and β waves was clearly distinguished from the other tasks. These data demonstrated the potential of various applications using the developed proof-of-concept upper extremity trainer to bring out an excellent rehabilitative effect not only through muscle growth but also via identification of large movement intentions inducing brain activation exercise.

Colorectal reconstructions following Hartmann’s procedure: challenges and solutions

The availability of a stoma after Hartmann’s procedure significantly limits the patient’s ability to work and worsens the quality of his/her life, as it partially isolates him/her from society. Performing plastic colon surgeries is challenging due to the active formation of intestinal adhesions and low rectal stump. At present many different devices, equipment, operating methods, and techniques have been proposed for reconstructive surgery on the colon. However, the issues of access to the surgical area, providing constant visual control, both at the stage of isolation for the short stump of the rectum in the narrow pelvis and in formation process of low colorectal anastomosis, are not covered in the scientific publications.
