[Problem] The present invention makes it possible to maintain the original function of a marine material when used in the state of being submerged in seawater or freshwater and also when stored or stocked in air before use, and also prevent marine pollution after use.
[Problem] The present invention makes it possible to maintain the original function of a marine material when used in the state of being submerged in seawater or freshwater and also when stored or stocked in air before use, and also prevent marine pollution after use.
[Solution] A constituent element of the marine material, which is used in the state of being at least partially submerged in seawater or freshwater, is made of a resin containing polylactic acid (PLA) and polybutylene adipate terephthalate (PBAT). As a result, when the constituent element is used in the state of being at least partially submerged in seawater or freshwater, and also when stored or stocked in air before use, hydrolysis in the constituent element is suppressed, while when it has landed on the seabed or riverbed after use, hydrolysis is promoted.

[Problem] To provide a fish sedating device that can reliably electrify and sedate fish for a successful slaughter operation. [Solution] This fish sedating device is characterized by comprising: a fish placement means 3 capable of placing fish F thereon; electrodes 4a, 4b for electrifying the fish F placed on the fish placement means 3 through high-resistance water that is present on the fish placement means 3 and that has a higher electrical resistance than the fish; and a power source for electrifying the electrodes 4a, 4b.
[Problem] To maintain the original function of a marine material when used in a state of being immersed in seawater or fresh water, and when stored or stocked in air before being used, and to prevent marine pollution after use. [Solution] At least a portion of components of this marine material that is to be used in a state of being immersed in seawater or fresh water is a resin containing polylactic acid (PLA) and polybutylene adipate terephthalate (PBAT). As a result, when at least a portion of the components is used in a state of being immersed in seawater or fresh water and when same is stored or stocked in air before being used, hydrolysis in the components is inhibited, whereas hydrolysis is accelerated when being placed on the seabed or river bed after use.

Abstract
[Problem] To provide a material for improving endometriosis with which it is possible to improve endometriosis and which is a material in which aglycone isoflavones are utilized, and a method for producing the material. [Solution] Production of a material for improving endometriosis, the material having aglycone isoflavones provided with an effect for improving endometriosis, and containing aglycone isoflavones that have beans as the raw material by: inoculating beans with koji mold to produce koji; adding water to the product of this koji-production treatment, thereby hydrolyzing the protein in the product and decomposing the glycosides of the isoflavone compounds in the beans; and producing isoflavone compounds that include a large amount of aglycone.

Abstract
The invention has a curved board. The curved board is formed into a shape that curves in a curving direction corresponding to an expanding direction of a net opening in a towing state, from a front-side end section that is a front side in a towing direction in the towing state towards a rear-side end section that is a rear side in the towing direction in the towing state. At least one of a projecting structure having a projecting surface, a top board, and a bottom board is formed in the curved board.
There is provided a net comprising a plurality of attack-resistant cords joined in a net mesh, wherein each attack-resistant cord comprises one or more hard metal wires running at least partially along its length and one or more high tenacity yarns having a tenacity of at least 1.5N/tex.

Abstract
Force for spreading a trawl net is significantly enhanced. A high lift otter board has a curved board (2) which is shaped to curve in the curving direction corresponding to the developing direction of a net mouth in the towing state from the front end which becomes the front side in the towing direction in the towing state toward the rear end which becomes the rear side in the towing direction in the towing state, wherein at least a bulging structure (4) having a bulging surface (3), a top plate (5) or a bottom plate (7) is formed in the curved board (2).
