Doping by athletes is a serious problem plaguing competitive sports around the world. Reviewing history, the traditional British endurance race is the source of doping in modern sports. Science and technology is the main driving force of social development. The competitive level of human beings has reached the height close to the limit of human potential, and it is difficult to improve sports performance by using conventional training methods, which makes athletes seek external and powerful means to improve their performance, and the achievements of natural science just meet this demand. This has also become a seemingly unavoidable phenomenon. On the one hand, this practice has been condemned by the public, on the other hand, it has become a serious problem in sports.

With the in-depth development and widespread application of educational informatization, digital education has also become one of the important features of educational modernization. Designing and completing a visual teaching system based on Web technology is of great significance for promoting further reform and development of teaching, especially for achieving remote education, which has great application value. Based on visual teaching needs analysis and B/S architecture, effective system development is achieved through Access database. According to the specific needs of teaching functions, the system can be divided into multiple modules, and the management and login of teaching resources for users can also be smoothly achieved. This has important research value for achieving the goal of remote visualization of teaching.

Socrates argues that individuals can continue to behave morally when trying to explore virtue, distinguishing between copying a moral person’s actions and acting on the basis of virtue itself. This study proves the limitations of South Korea’s moral education, which values moral knowledge as a driver of moral behavior, by analyzing the art of measurement presented by Socrates as a method of recognizing virtue. Consequently, Protagoras was examined to identify the characteristics of the art of measurement, and “all pleasure is good” and “knowledge directly drives action” was problematized. The study concluded that moral knowledge is not a decisive factor in guiding moral behavior in the right direction.

What is “truth”? This is the main philosophical question that many of the contemporary philosophical theories (e.g., consistency theory, correspondence theory, semiotics, and pragmatism) tried to investigate over the past decades. However, these theories mostly approached “truth” from logical and epistemological perspectives. On the other hand, Santayana’s theory of truth embarks in a different direction. His perspective was laid out in his book “The Realm of Truth”, which is considered one of the parts of his seminal work “The Realms of Being”. Santayana's theory of truth founded on the “critical realism” to which he belongs, and thus his approach was “realistic” or “ontological”. The novelty of Santayana's theory of truth is that it brings the “theory of truth” out of the fields of logic, epistemology, and philosophies of language, and into the field of being, ontology, or the realm of lived experience. In this paper we introduce an analytical and critical account of Santayana's theory of truth, and its moving from logic to realism.

All sectors have an increasing interest in smart phone applications based on their many advantages that support business, especially the medical sector, which is constantly competing to develop the medical services provided, and accordingly in this research study we industrialized a mobile medical supplies and equipment ordering application (mobile medical app) classic and make an effort to authenticate it factually. When clients (hospitals doctors) create consumptions on the application, three dimensions can be identified: platform emotion stage, fear effect, and familiarity with product. This research designed to reinforce and brighten the most important magnitudes that improve a physician’s judgment of mobile medical app and the purpose to usage. Furthermore, this study inspected the availability of the model between hospital physicians in UAE. The classic ideal was observed by means of a model of 340 UAE clinic physicians and their personal assistant who utilize mobiles facilities in overall. The review technique, a calculable method, was applied; the fractional smallest cubes organizational calculation exhibiting systems was owned to inspect the planned agenda. The platform emotion dimension, especially fear and resistance to change, and the familiarity with the products were evaluated, and it was discovered that these factors positively influenced the objective to use the application. And the other side, the first dimension of emotion, fear, manifested as “apparent threat”, had no outcome on the purpose to using. These discoveries recommended that scholars should emphasis more on the facilities, merchandises, and the key task of the mobile medical app to control their inspirations on clients’ ordering purpose. This will progress the purchasing ways associated to acquiring medicinal materials utilizing mobile medical app and/or on other operational stages in unambiguously in UAE and the Central East at great.
