Проверка представлений о кариесогенной ситуации при помощи таблиц истинности

Abstract

У роботі зроблена спроба за допомогою побудови таблиць істинності визначити, наскільки правильні уявлення Кейза. Для побудови таблиць істинності було використано онлайн калькулятор, оскільки подібні програми, розміщені в інтернеті, значно скорочують витрачаємий надані операції час. В результаті проведених досліджень випливає висновок про недоцільність збільшення величин, які корелюють між собою, про що нами було вказано в одній із зазначених вище наших робіт. Все вищеперелічене говорить про те, що межі, в яких відбувається каріозний процес, не визначені і не існує міри, якою можна опрерувати при роботі над дослідженням цього феномена; В работе сделана попытка при помощи построения таблиц истинности определить, насколько правильны представления Кейза. Для построения таблиц истинности использован онлайн калькулятор, поскольку подобные программы, размещенные в интернете, значительно сокращают затрачиваемое на данные операции время. В результате проведенных исследований следует вывод о нецелесообразности увеличения коррелирующих между собой величин, о чем нами было сказано в одной из указанных выше наших работ. Все вышеперечисленное говорит о том, что границы, в которых происходит кариозный процесс, не определены и не существует меры, которой можно опрерировать при работе над исследованием этого феномена; Introduction. In previous works, building on the provisions of the Case using logical constructs, we proposed a system in which the carious process is implemented. The title of the first of these sources, as a result of the correction, there was a tautology. In fact, the title of the article sounds like a “Status of methodology in cariesology and opportunities for its improvement” that can be seen from the English summary of this work. The purpose of the study. For this purpose, us can use a method such as tabulations truth. These tables are most frequently used in Boolean algebra, as well in similar systems multivalued logic. Subject and methods. In this paper, we will try using this technique to determine how well the provisions of the Case’s. To construct the truth tables, we will use an online calculator, such as this program situated in the Internet, significantly reducing spent on these operations time. Results and discussion. Recall that according to the theory of the Case’s caries develops only when the coincidence of the three conditions: cariogenic microflora, digestible carbohydrates and low resistance of enamel. When translated into the language of his charts of logical operations such actions correspond to the conjunction (logical multiplication) – a ˄ b ˄ c, where: a - the low resistance of enamel; b - digestible carbohydrates; с - cariogenic microflora. Only by combination of these three factors can occur caries. However, we know that subsequent researchers have perfected the concept of cariogenic situation, adding such factors as the time. Logical formulas such statements will also be represented by a conjunction – a ˄ b ˄ c ˄ d, where: a - the low resistance of enamel; b - digestible carbo¬hydrates; с - cariogenic microflora: d - time. Only when the coincidence of the four conditions can be tooth decay. Let’s try to add a fifth factor, such as the regular use of fluoridated toothpaste. Logical formulas such statements will be presented again conjunction – a ˄ b ˄ c ˄ d ˄ e, where: a - the low resistance of enamel; b - digestible carbo-hydrates; с - cariogenic microflora: d - time; e - the regular use of fluoridated toothpaste. Only in the presence of these five factors can be the tooth caries. However, regular use of fluoridated toothpaste, as we know, has the opposite effect. From these judgments clearly that the accumulation of such elements in the logical construction can lead us to the wrong understanding of the phenomenon of caries. Conclusion. From the above it follows that the increase correlation each other quantities is not always indicative of a direct link between them. Indirect communication may also have a huge number of intermediaries, which threatens might fail in finding the true relationship between variables. It also follows the conclusion of inappropriate increase in the quantities correlated with each other, as we mentioned in one of the above-mentioned our work. All of the above suggests that real border, in which there is carious process to date has not identified and there is no action that can be measure when working on the study of this phenomenon, which affects both its meaning and its research.
