Abstract: A smart farm platform is disclosed for determining recommended selling prices of agricultural products based on state information of the agricultural products and operation history information of a plant grower, among information received from the plant grower, and a terminal displays the recommended selling prices of agricultural products through a display.

Abstract: A space is set substantially in a tropical rain forest type environment to activate a human's essential brain region and realize an environment suitable for the human's brain by arranging a device for setting the tropical rain forest type environment based on characteristics of activating human's essential brain region responsive to tropical rain forest type environment information, in a space such as an urban space, a housing space or other living space. The tropical rain forest type environmental information has higher density and higher complexity than those of urban space type environmental information, and includes at least one of auditory information, visual information, and super perceptual information of aerial vibration. The tropical rain forest type environmental information is comfortable for the human with no excessive stress, and is environmental information for effecting prevention and treatment of diseases due to stress by realizing the environment comfortable for the human's brain.

Abstract: A means is provided for generating a vibration or a vibration signal, which contains audible range components that are vibration components in the audible frequency range and super-high-frequency components within a range exceeding the audible frequency range up to a predetermined maximum frequency, and which has an autocorrelation order represented by at least either one of a first property and a second property. By applying the vibration or an actual vibration generated from the vibration signal to a human being, a fundamental brain activation effect activating the fundamental brain network system constituted of a fundamental brain including the brain stem, thalamus and hypothalamus that are regions to bear the fundamental function of the human being and the fundamental brain network of neuronal projection from the fundamental brain to various brain regions is introduced.

Abstract: A vibration presenting system includes a first vibration applying device for applying a vibration that is generated by a first vibration source and has frequency components within an audible range perceivable as a sound by an auditory sense system of a living body to the auditory sense system of the living body, and a second vibration applying device for applying a vibration that is generated by a second vibration source different from the first vibration source and has superhigh frequency components exceeding the audible range unperceivable by the auditory sense system of the living body to a living body component region other than the auditory sense system of the living body. The living body component region other than the auditory sense system of the living body is a body surface of the living body, which may include a head thereof.

The tropical rain forest type environmental information is comfortable for the human with no excessive stress, and is environmental information for effectively functioning on prevention and treatment of diseases due to stress by realizing the environment comfortable for the human's brain.

Abstract: In a sound generating apparatus, a sound generating space, a sound, and a method for generating a sound, a sound is generated which has a frequency within a first frequency range beyond a predetermined audible frequency range and up to a predetermined maximum frequency, and which is non-stationary so as to change in a micro-temporal area in a second frequency range beyond 10 kHz. Then, the generated sound is applied to a person, thereby increasing cerebral blood flows of the person. This causes improvement and enhancement of the person's state of mind and body, so as to relieve stresses, thereby relaxing the person.
