Provided are an underwater radiation monitoring system and method. The monitoring system includes a plurality of sensors configured to measure a value of underwater radiation in a measurement area in which underwater radiation is to be measured, the plurality of sensors being installed in the measurement area by being arranged in a form which is set on the basis of information about the measurement area; and an electronic device configured to identify a value of underwater radiation in the measurement area on the basis of the values of underwater radiation measured by the plurality of sensors, wherein at least one first sensor among the plurality of sensors is connected to the electronic device to collect measured values obtained from the at least one first sensor and a plurality of second sensors excluding the at least one first sensor and to transmit the collected measured values to the electronic device.

Underwater radiation monitoring system and method

A method for producing lysophosphatidylethanolamine 18:1 includes extracting phospholipids including mainly phosphatidylethanolamine from a microorganism ofsp. and treating the extracted phospholipids with phospholipase A2. An alternative method for producing lysophosphatidylethanolamine 18:1 includes treating a microorganism ofsp. directly with phospholipase A2. The lysophosphatidylethanolamine 18:1 can be used as a plant vaccine material for preventing the plants from injuries caused by pathogen infections and/or environmental stresses and accelerating the recovery of plants injured by pathogen infections and/or environmental stresses, and can also be used as a composition for enhancing fruit ripening (color and sweetness) and storage properties, and as it can be used for an application in plant tissues, food products, pharmaceuticals, cosmetics, and agricultural use, it would be very advantageously used in related industries. This invention also provides a method of producing a phosphatidylethanolamine itself from a microorganism ofsp.

This invention relates to a method of preparing a radioisotope nanostructure having a ligand-metal framework, and a radioisotope nanostructure prepared thereby. The method of preparing the radioisotope nanostructure of the invention has a simple preparation process and can thus be applied to mass production of a radioisotope nanostructure. Also, because this radioisotope nanostructure is nano-sized spherical particles and has no reactive group, it can be easily dispersed in a fluid, and this nanostructure is physically and chemically stable and thus can be utilized as a radioisotope tracer in the fields of refineries, chemistry, cement, agriculture, water resources, marine, etc. Furthermore, this nanostructure can be used for diagnosis and/or treatment in medical fields, and can be applied to checking whether a nanomaterial is harmful. In addition, this nanostructure is expected to be applicable in a variety of fields using radioisotopes.
