Problems of Teeth and Gums Expert System

Our gums (gingiva) act as a significant barricade in guarding our teeth and their neighboring support structures. A tiny known fact is that gum disease is the foremost cause of tooth loss in grown persons. Healthy, strong, teeth are reliant on on healthy gums. The core culprit for gum problems is bacteria in dental plaque. The bacteria in plaque yield harmful toxins that generate an inflammatory process that happens in the gum tissue. If left for a sufficient period of time, bacterial plaque causes hurt to our teeth as well as our gums. In this paper, we present a knowledge based system that help people with teeth and gums problems to diagnose their problems and get recommendation for the treatment. This expert system was designed and implemented using SL5 Object language for knowledge based system

PM10 emitted from gravel crushers and their effects on complete blood counts for workers, middle gover-norate–Gaza, Palestine

Case-control study was conducted during the period from April to August, 2013 on all gravel crushers at Middle Gaza Governorates. There were 87 individuals participants invloved in this study, out of which 40 were case (exposed) and 47 control (non-exposed) groups respectively. PM10 (Particulate matter with an aerodynamic diameter of 10 micrometer or less) concentration level was measured in the six crushers, and all participants were subjected to Complete Blood Counts (CBC). This was conducted to evaluate the level of PM10 air pollution in crusher’s plants, and their impacts on complete blood counts (CBC) for crushers workers. Results showed that an average of particulate matter contributions is 15153 μg/m3 (microgram/cubicmeter), which is about 100 times higher than PM10 existing standard of 150 μg/m3. As well as, it showed clear links between PM10 exposure and CBC changes among exposed group. Increasing in white blood cells count were more common among the exposed group, whereas in the non-exposed group, CBC did not change. Therefore, we can conclude that PM10 concentration level in crushers plants were much higher than the existing standard. Occupational exposure to PM10 leads to CBC changes especially increasing in white blood cells count

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning

The Digital Trust : A qualitative study of the generation millennials’ attitudes toward and trust in the Bitcoin cryptocurrency and its value

Purpose: The purpose of this study is to develop an understanding of millennials’ attitudes toward and trust in the Bitcoin cryptocurrency and its value. The study also aims to analyze what this trust is based on. Theoretical frame of reference: Several theories are used to formulate a theoretical frame of reference. The theories of planned behavior, Word of mouth and Electronic Word of Mouth concern consumer behavior and are applied to millennials’ in this case. To take into account the value of Bitcoin, the study also incorporates the theory of trust in technology, which discusses among other things, how trust in technology is essential as it influences whether a person will use the product or service. Methodology: The study uses a qualitative method based on 12 semi-structured interviews conducted via Zoom or Skype. The selection for this study is made through goal-directed selection, which is a selection of respondents who to some extent have knowledge of, or affected by, what the study intends to analyze. Conclusion: The conclusion indicates that millennials who have information about cryptocurrency in advance tend to experience more confidence in Bitcoin, as it is based on their information about the technology behind Bitcoin. Millennials also experience trust in Bitcoin according to their perception that it is not controlled by a third party; however, the cryptocurrency’s value depends on how it is liked by its investors or users. The respondents with a negative attitude were found to lack general information about the cryptocurrency and were, therefore, unwilling to accept the risks that accompany it. The respondents with a positive attitude proved to have confidence in the technology behind Bitcoin and, therefore, spread positive information about it by Word of Mouth.
