Summary
A new touchscreen version of DriveSafe effectively identifies at-risk drivers by automatically scoring environmental awareness. This cognitive screening tool accurately differentiates drivers needing further evaluation based on hazard identification accuracy.
Area of Science:
- Gerontology
- Human Factors Engineering
- Cognitive Psychology
Background:
- DriveSafe assesses driving environment awareness as part of the DriveSafe DriveAware cognitive fitness-to-drive screening.
- The DriveSafe tool was adapted to a touchscreen format for simplified administration.
- An automated data collection and scoring system was developed to replace expert rater decisions.
Purpose of the Study:
- To develop and validate an automated scoring system for the touchscreen DriveSafe.
- To determine if the scoring parameters can differentiate at-risk drivers from a comparison group.
Main Methods:
- Thirty at-risk older drivers and 30 younger comparison drivers completed the touchscreen DriveSafe.
- Participants recalled object/hazard details (type, location, movement) by touching the screen after image presentation.
- Scoring parameters were analyzed using descriptive statistics and Fisher's exact test.
Main Results:
- The automated scoring system successfully discriminated at-risk drivers from the comparison group.
- At-risk drivers exhibited significantly higher rates of missed or misidentified object types, directions, and locations.
- Significant differences (P < 0.05) were found in 24 of 28 location zones and 18 of 28 direction ranges.
Conclusions:
- The automated data collection and scoring system accurately reflects expert rater decisions.
- This system effectively discriminates between at-risk and comparison drivers.
- Further psychometric evaluation is needed before clinical implementation of touchscreen DriveSafe.

01:14Design Example: Resistive Touchscreen
735
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

01:30Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors
2.5K
Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

01:18Additional Routes of Drug Administration
4.9K
Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

01:18Routes of Drug Administration: Enteral
6.4K
Medications can be administered through the enteral route using liquids, capsules, or tablets.
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

01:25Routes of Drug Administration: Parenteral
2.9K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

01:22Routes of Drug Administration: Overview
9.6K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
