Abstract: In accordance with the present invention, a plurality of routers in more than one network based on different protocols can be integrally managed. The management system of the present invention is capable of integrally managing a plurality of routers in a network based on IPv6 from another network based on IPv4, wherein a relay server receives the identification data from a router, and transmits it to a LAN server. The LAN server uses the received identification data, and pushes the configuration data prepared in advance for the accessing router into the router. The relay server, which has a converting function between IPv4 and IPv6, manages the network on the routers side by IPv6 while it manages the network on the LAN server's side by IPv4.

Abstract: Porphyran with modified bioactivity and physical property, method of making the modified Porphyran and use of modified Porphyran. Porphyran with modified bioactivity and physical property is produced by dissociating a salt from a sulphate group in Poryphran and removing it, making Porphyran having a free sulphate group wherein a salt is dissociated. Further, Porphyran with modified bioactivity and physical property is produced by dissociating a salt from sulphate group in Porphyran and removing it, and then altering the sulphate group, with the use of a given salt, into a sulphate salt of the given salt. The modified Porphyran also can be obtained by converting a salt of a sulphate group in Porphyran into a sulphate salt of a given salt by ion exchange. The modified Porphyran be added to cosmetics, food, and drink, and used as cosmetic, food and drink having inhibitory activity against hyaluronidase activity.

Abstract: A heat pump type hot water supply apparatus (10) for heating water by refrigerant heat and stocking the hot water thus achieved including: a heat pump unit (11) having a refrigerant circuit using natural refrigerant, the refrigerant circuit including a compressor (16) for compressing refrigerant, a heat-pump heat exchanger (18) and a refrigerant-water heat exchanger (27) for performing the heat exchange between refrigerant and water to achieve hot water; a hot water supply unit (12) including a hot water supply tank (26) for stocking the hot water achieved by the refrigerant-water heat exchanger (27) of the heat pump unit (11) and supplying the hot water thus stocked; and a water pipe (36) through which the refrigerant-water heat exchanger (27) of the heat pump unit (11) and the hot water supply tank (26) of the hot water supply unit (12) are connected to each other to circulate hot-water/water between the refrigerant-water heat exchanger (27) and said hot water supply tank (26).
