Abstract: An environmental control method, including: receiving settings of a favorite emission color of light that the subject likes and an unfavorite emission color of light that the subject does not like; and switching between first control and second control at a predetermined timing, the first control making a function of a sympathetic nervous system of the subject dominant over a function of a parasympathetic nervous system of the subject by causing an indirect lighting apparatus disposed in a space in which a subject is located and capable of changing an emission color of light to emit light having the unfavorite emission color of the subject received, the second control making the function of the sympathetic nervous system of the subject dominant over the function of the parasympathetic nervous system of the subject by casing the indirect lighting apparatus to emit light having the favorite emission color of the subject received.

Abstract: An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which obtains at least one time included in a scheduled wake-up time of the subject, a scheduled go-to-bed time of the subject, a sunrise time, and a sunset time, and switches control on the wind blower at the at least one time obtained.

Abstract: An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which performs control that makes a sympathetic nervous system of the subject dominant over a parasympathetic nervous system of the subject by changing a wind speed of the wind that is blown by the wind blower at a cycle in a range from 15 minutes to 60 minutes and by setting a time in which the wind speed is a smallest value to less than or equal to 75% of the cycle.

Abstract: An environmental control system includes: an air conditioner for adjusting a temperature in a space in which a subject is located; and a control apparatus which performs control that makes a parasympathetic nervous system of the subject dominant over a parasympathetic nervous system of the subject by performing first control and second control using the air conditioner. The first control increases the temperature in the space, and the second control cyclically changes the temperature in the space in such a manner that a temperature difference from a largest value to a smallest value in the space falls within 3 degrees Celsius.

Abstract: An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which switches between first control and second control at a predetermined timing. The first control makes a sympathetic nervous system of the subject dominant over a parasympathetic nervous system of the subject by changing a wind speed of the wind that is blown by the wind blower at a predetermined cycle, and the second control makes the parasympathetic nervous system of the subject dominant over the sympathetic nervous system of the subject by decreasing a wind speed of the wind that is blown by the wind blower to a wind speed lower than the wind speed in the first control.

Abstract: The semiconductor device includes: an AlGaN layer; a contact electrode; an insulating film; and a passivation film. The semiconductor device further includes: an extended wire extending over the contact electrode and the insulating film; and a pad electrode electrically connected to the extended wire. The passivation film covers the insulating film and the extended wire and including an opening for exposing the pad electrode. The insulating film accommodates the opening in a plan view. The passivation film accommodates the contact electrode in a plan view. The semiconductor device further includes a heat dissipation layer on a surface of the passivation film.
