The paper presents the results of quantitative studies of the heart rate variability detected when the subject was exposed to the preferred light stimulus with a wavelength of 460 nm (blue color). The use of the variational pulsometry method showed the possibility of assessing the state of homeostasis, the interaction of sympathetic and parasympathetic regulation circuits. In the course of the experiment, the activity of various links of the regulatory mechanism was assessed and a general picture of the adaptive response of the organism to the preferred blue light was revealed.
The Tibetan method of pulse diagnosis takes a prominent place among various diagnostic approaches. A considerable knowledge base for diagnosing various pathological states of the human body on the basis of pulse parameters has been accumulated [1], and the information stored in the knowledge base is sufficiently large and structurized to be described in formal terms.Research studies of recent years have shown that the problem of formal description of the information on the Tibetan pulse diagnosis is solvable in principle [3, 5,6]. Sensor devices for detecting pulse signals and general methodological approaches to the signal processing have been developed. There is an opportunity to compile a pulse signal catalog or a database of quantitative and qualitative formal descriptions of pulse signals that correspond to various nosological forms discernable by Tibetan medicine. The development of the database would allow implementation of automatic diagnostic methods. In addition to Tibetan medical experts, the solution of the problem requires that European medical physicians be involved. This also requires a qualitatively new software to be developed.The developed software should meet the requirement of completeness of entered and stored information, functional flexibility, and it should have a friendly user interface.Diagnostic information should be stored on hard disk. It contains the patient questionnaire (name, date of birth, age, sex, height, body weight); informal verbal description and expert evaluation of patient's pulse (in terms of traditional Tibetan medicine); preliminary verbal diagnosis (in terms of European medical nosology) if necessary; pulse signals recorded from an analog-to-digital converter; service information, including experimental settings (sampling frequency, duration of testing, amplification coefficients of pulse probes, etc.). In addition, each file contains information on the results of data processing by various algorithms, data identification, the structure of the data, and their detailed description. This model allows easy data processing and comparison between various expert descriptions of pulse signal and its formal evaluation.The developed software is based on the concept of object-oriented programming (OOP) because this allows a compact package and fast coding/decoding. The software is implemented in an IBM PC computer under MS DOS. Basic OOP features (encapsulation, non-transparency, inheritance) were implemented by a standard procedural language (Pascal) [2] and by specific programming technology. The principle of the technology is that the program is composed of individual modules connected by object links. The input/output and data processing procedures were considered as abstract methods. Each method implements a specific algorithm of data arrangement in accordance with internal variables. The output information of each method is tagged and identified by a special control algorithm. In general, the data processing includes the following operations: structuring of input data an...
