概括
在YouTube上支持化物的视频更可靠,但反化物内容在易于理解的情况下获得了吸引力. 仅仅是科学准确性并不能保证口腔健康信息的参与.
科学领域:
- 口腔健康沟通口腔健康沟通
- 健康信息传播 传播健康信息
- 数字健康素养 数字健康素养
背景情况:
- YouTube是健康信息的重要平台,包括化物.
- 评估支持和反化物含量的质量和参与度对于公共卫生至关重要.
- 了解影响受众接触健康信息的因素至关重要.
研究的目的:
- 在可理解性,可操作性,流量,可靠性和参与度方面,比较支持和反对化物的日本YouTube视频.
- 用验证的工具评估与化物相关的视频内容的质量.
- 分析视频特征与观众参与度 (查看率) 之间的关系.
主要方法:
- 分析了84个日本YouTube视频 (49个是支持化物,18个是反对化物,17个是其他).
- 使用PEMAT-A/V,全球质量评分 (GQS) 和修改后的DISCERN (mDISCERN) 评估视频质量.
- 通过查看率来衡量参与度,并将其与可理解性和质量指标相关联.
主要成果:
- 与反化物视频相比,支持化物的视频显示出更高的可靠性 (mDISCERN) 和整体质量 (GQS).
- 在支持和反对化物的视频之间,在可理解性或可操作性方面没有发现显著的差异.
- 在反化物视频中,更高的浏览率与更好的可理解性和GQS相关;在支持化物视频中,这种相关性不存在.
- 只有27%的视频达到PEMAT-A/V的可理解度值.
结论:
- 虽然可靠的反化物视频的覆盖范围有限,但易于理解的反化物内容可以实现更广泛的参与.
- 仅仅科学准确性并不能保证观众在YouTube上达到或参与.
- 口腔卫生当局应该创建清晰,可操作和算法意识的,以证据为基础的视频,以改善公共卫生信息.

pH
The potential of hydrogen (pH) is a measure of the acidity or basicity of a water-based solution determined by the concentration of hydronium ions (H3O+). In one liter of pure water at neutral pH, there are 1×10−7 moles of hydronium ions. However, the extensive range of hydronium ion concentrations present in water-based solutions makes measuring pH in moles cumbersome. Therefore, a pH scale was developed to convert moles of hydronium ions into the negative logarithm of the hydronium ion...
Determining the pH of Salt Solutions
The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution. In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7. For...
Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene
Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.
Effects of Chemicals: Overview
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
