Bloodletting at the ear apex for acute stroke: A systematic review and meta-analysis of randomized controlled trials.

Background: Stroke is a major cause of death and disability worldwide. Despite innovative developments in acute stroke treatment techniques in modern society, many stroke survivors still experience complications, leading to a demand for complementary and alternative medicines, including traditional medicine. Bloodletting at the ear apex (BLEA) is a nonpharmacological intervention used for various diseases, including acute stroke, in traditional medicine in East Asian countries, including China and Korea.

System-level interventions for fall risk assessment, fall prevention and fall injury prevention in long-term care facilities: a scoping review.

Objectives: Older adults living in long-term care facilities (LTCFs) are at high risk for falls. Interventions to prevent falls and fall-related injury in this population may be individual-level or system-focused interventions. However, relatively little attention has been given to research on system-focused interventions.

Bloodletting for Acute Stroke Recovery: A Systematic Review and Meta-Analysis.

Background: Bloodletting is a non-pharmacological treatment commonly used for acute stroke in traditional East Asian medicine. This study evaluated the efficacy and safety of bloodletting in acute stroke recovery.

Methods: We conducted a comprehensive search of eight electronic databases up to 4 June 2024 to identify relevant randomized controlled trials (RCTs).

A novel design of journal bearings for stability under shock loads.

Mechanical systems are expected to operate under various load conditions, and it is necessary to use a lubrication system to achieve reliability and stable performance. Journal bearings, which are used to achieve such stable lubrication, are representative of hydrodynamic lubrication bearings. In this study, groove-shaped structures and rubber were applied to the ends of the bearings to ensure stable lubrication performance under conditions where, for various reasons, shock loads are applied in addition to static loads under misaligned conditions.

Investigating Factors Influencing the National Cancer Screening Program among Older Individuals in Republic of Korea-Data from the Korea National Health and Nutrition Examination Survey VIII.

This study aims to determine the influencing factors of the participation of older individuals aged 65 years and above in South Korea's National Cancer Screening Program (NCSP) using data from the eighth wave (2019-2021) of the Korea National Health and Nutrition Examination Survey (KNHANES VIII), and discuss potential problems and coping strategies. Variables were selected based on Andersen's healthcare utilization model. "Participation in the NSCP" was considered the dependent variable, with independent variables including sociodemographic characteristics (sex, marital status, residence, education level, income level, economic activity, medical coverage type, and private insurance), health conditions (subjective health status, hypertension, and diabetes), and health behaviors (physical activity, monthly alcohol consumption, and current smoking status).

Numerical Analysis for Appropriate Positioning of Ferrous Wear Debris Sensors with Permanent Magnet in Gearbox Systems.

In order to improve the measurement sensitivity of ferrous wear debris sensors with a permanent magnet, a new numerical approach to the appropriate position of the sensor is presented. Moreover, a flow guide wall is proposed as a way to concentrate flow around the ferrous particle sensors. The flow guide wall is intended to further improve measurement sensitivity by allowing the flow containing ferrous particles to flow around the sensor.

Numerical Approach and Verification Method for Improving the Sensitivity of Ferrous Particle Sensors with a Permanent Magnet.

This study aimed to improve the sensitivity of ferrous particle sensors used in various mechanical systems such as engines to detect abnormalities by measuring the number of ferrous wear particles generated by metal-to-metal contact. Existing sensors collect ferrous particles using a permanent magnet. However, their ability to detect abnormalities is limited because they only measure the number of ferrous particles collected on the top of the sensor.

Varnish Formation and Removal in Lubrication Systems: A Review.

This study presents the current literature regarding the investigation of varnish contamination among the various types of lubricant contaminations. As the duration of use of lubricants increases, the lubricant deteriorates and may become contaminated. Varnish has been known to cause filter plugging, sticking of the hydraulic valves and fuel injection pumps, flow obstruction, clearance reduction, poor heating and cooling performance, and increased friction and wear in various lubrication systems.

Assessment of Condition Diagnosis System for Axles with Ferrous Particle Sensor.

This study presents a condition diagnosis system based on a ferrous particle sensor to estimate the durability of axles in construction equipment. Axles are mechanical devices that play the role of the differential gear in construction equipment that move with wheels and require high reliability. In the durability testing of new axles, failure identification and real-time diagnosis are required.

Application of Condition Monitoring for Hydraulic Oil Using Tuning Fork Sensor: A Study Case on Hydraulic System of Earth Moving Machinery.

In this study, we focus on the correctness of oil condition monitoring, specifically of a tuning forks sensor in hydraulic systems. We also aim to analyze the correlation between the online monitoring sensor signal and offline oil analysis by periodically sampling the hydraulic oil. In recent years, condition-based monitoring (CBM) of hydraulic oils has played a key role in extending earthmoving machinery uptime and reducing maintenance costs.
