Conventional bio-probes are produced on a silicon substrate, they are not only fragile but unable to dispose according to the profile of human body in a large area manner, and thus the contact resistance between probe and skin may be increased. Besides, the signal processing devices are required to improve both S/N ratio and impedance matching problems. This paper proposes a novel remote human health monitor and an active RFID tag with replaceable non-frangible probes and thin-film-transistor (TFT) amplifiers. The probes are made of bio-degradable polymer (photo resist) and covered with bio-compatible TiN. In addition, we use two pieces of double sides conducting tapes to connect both TFT amplifiers and probe modules. Thus the probe module can be replaced easily by peeling the used probe module away from the double sides conducting tapes to supply a new one. Since the tag is a flexible plastic substrate, e, g. PT, PET and PI, so the probes are easier to deploy and conform to the human body profile. In addition, the signal can be amplified by the TFT amplifier nearby to improve both S/N ratio and impedance matching. Thus the human health conditions can be remotely monitored by measuring various acupuncture impedances via the active RFID tag. The active RFID monitoring range is 15m by using 2.45 GHz ISM band, the probe resistance and parasitic capacitance are as 2735 Ω and 60.7 pf, respectively. Since the typical human acupuncture point resistance is about 40-120KΩ, thus the proposed device and system can be applied.

The salt water mixes with fresh water and forms brackish water. The brackish water contains some quantity of salt, but not equal to sea water. Salinity determines the geographic distribution of the number of marshes found in estuary. Hence salinity is a very important environmental factor in estuary system. Sand is one major natural aggregate, required in construction industry mainly for the manufacture of concrete. The availability of good river sand is reduced due to salinity. The quality of sand available from estuarine regions is adversely affected due to this reason. It is the responsibility of engineers to check the quality of sand and its strength parameters before using it for any construction purpose. Presence of salt content in natural aggregates or manufactured aggregates is the cause for corrosion in steel. In this study the amount of salinity present in estuary sand was determined. Three different methods were used to determine the salinity in different seasonal variations. The sand sample collected nearer to the sea was found to be high in salinity in all methods.  It can be concluded that care should be taken before we use estuary sand as a construction material due to the presence of salinity.

Assessing flood risk and detecting changes of salt water inflow in a coastal micro-tidal brackish marsh using GISIn order to assess changes in salt water inflow and potential flood risks due to sea level rise in a micro-tidal Beka brackish marsh on the Polish Baltic Coast GIS was used. Such wetlands are important elements of coastal zone natural environments. Creating a geodatabase within a GIS system makes it possible to carry out broad analyses of complex systems, such as coastal wetlands. The results indicate that a 40 cm sea-level rise would considerably increase the frequency of flooding in the investigated area, in part because of the small range of the annual sea level oscillations there. A map of the index of changes in saltwater inflow, created with the help of cost-weighted distance (functions), shows that changes which have occurred along the shore, consisting of filling in the drainage channel outlets, have likely had a significant impact on the vegetation of the area.
