Abstract: Proposed is a board game system for carbon neutrality education including: a game display unit including a game board, general cards having carbon cards on which carbon emission quantities are indicated and environment cards on which carbon absorption quantities are indicated, disaster cards on which climate crisis disasters are indicated, convention cards on which rights to change greenhouse gas target amounts are indicated, earth money cards on which scores are indicated, and an indicator for indicating the level of global warming and carbon emission targets; and a game control unit for controlling the game display unit to display the general cards, the disaster cards, the convention cards, the earth money cards, or the indicator on the game board.

Abstract: Provided is a method for setting a thermal comfort scale of an age-specific perceived temperature of residents living in a certain area based on an experiment exposed to thermal stress environment in an artificial climate chamber.

Abstract: Disclosed in an air conditioner including a control box having a space formed therein, a PCB arranged to form an air circulation passage in the space, the PCB having a plurality of electric components mounted thereto, a cooling module for making a first electric component of the plurality of electric components to heat exchange with refrigerant, and a circulating fan arranged in the air circulation passage to make air to flow to a second electric component of the plurality of electric components after cooled by the cooling module, thereby dissipating heat from an inside of the control box with a mixed cooling system of a refrigerant cooling system and an air cooling system, efficiently.

Abstract: An apparatus for meteorological observation is provided. The apparatus includes: a body part; a coupling part which moves along a first and a second guiding routes alternatively by a motor; a sensor part which rotates according to a movement of the coupling part; and a shoot controlling part for measuring data of the upper atmosphere when the coupling part is placed on the top guiding member while moving along the first guiding route, (ii) measuring data of front lower atmosphere when the coupling part is placed on the first branch while moving along the first guiding route, (iii) measuring data of the upper atmosphere when the coupling part is placed on the top guiding member while moving along the second guiding route, and (iv) measuring data of rear lower atmosphere when the coupling part is placed on the second branch while moving along the second guiding route.

Abstract: A method for estimating a position of a target by using an image acquired from a camera is provided. The method includes the steps of: (a) setting multiple virtual estimated reference points by dividing a view-path; (b) comparing altitude values of the respective estimated reference points with those of respective points on terrain; (c) searching neighboring virtual estimated reference points among the multiple virtual estimated reference points to satisfy a requirement under which a difference between an altitude zk of one point among the neighboring estimated reference points and that of the terrain corresponding thereto and a difference between an altitude zk+1 of the other point among the neighboring estimated reference points and that of the terrain corresponding thereto have different signs; and (d) determining that the actual position of the target exists between the searched estimated reference points Pk.

Abstract: The present invention proposes a water circulation system associated with a refrigerant cycle that can selectively heat-exchange water for cooling and heating and hot water supplying with at least one of a first refrigerant and a second refrigerant. Therefore, the present invention can improve the operation efficiency of the water circulation system associated with the refrigerant cycle.
