Introduction. Concept Statement: Human Being in Nursing Theory Human beings are regarded as open energy fields, possessing unique experiences. They could be placed in broader contexts and, therefore, they differ from the unity of their parts that are impossible to predict based on knowledge of separate parts. As holistic beings, humans are represented as sentient, dynamic, and multidimensional entities who are capable of creativity, abstract reasoning, self-responsibility, and aesthetic appreciation. Further, human could also be considered unique individualities due to the peculiarities of language, caring, and empathy patterns that a person employs while interacting in a social environment. From spiritual and moral viewpoints, humans are defined as valued, respected persons who are understood with the right to making choices concerning their health. All these dimensions of concept analysis are considered in various theories, particularly in Johnson’s Behavior System Model and Science of Unitary Human Being. Describing the Concept within Two Nursing Theories Johnson’s Behavior System Metaparadigms According to Dorothy Johnson, the founder of the behavior system model, human beings should be evaluated from the perspective of two main systems: the behavior system and the biological one. The task of the medicine consists in resorting to the biological system, whereas the main scope of nursing is confined to focusing on the behavioral system (Theoretical Foundation of Nursing, 2011). At this point, the concept of human being could be regarded as the behavioral model that seeks to make constant adaptations to maintain, regain, or achieve balance to the state that implies the adjustment process. Philosophies According to Johnson’s Behavioral System Model, nursing focuses on promoting efficient behavioral functioning of a patient for the purpose of noticing and preventing illness. At this point, the patient is presented as a behavioral system that consists of seven subsystems, including dependency, affiliative, ingestive, sexual, eliminative, achievement, and aggressive (Theoretical Foundation of Nursing, 2011). There are three functional requirements that imply protection from harmful influence, motivation for growth, and insurance of a nurturing environment. The failure of any of the described systems can lead to disequilibrium. At this point, the main role of nurses lies in assisting the patients in sustaining the balance. Additionally, it should be stressed that the theory focuses solely on individual level and, therefore, its basic concept does not cover families, relatives, groups and communities (Theoretical Foundation of Nursing, 2011). The main concept defines how a person’s behavior is represented in terms of psychological development. Classifying various types of behavior within the proposed seven subsystems allows nurses to work out specific interventions. The quality of case provided by the nurse can be diminished as a result of fractionalized care that does not support a holistic approach to treating an individual. Conceptual Model The nursing model is used to measure the patient progress along with the managerial determination of the personnel levels. The importance of the proposed model is applicable to both nurses and their patients and relies on d
