Abstract:
The present invention provides a technique for adsorbing I-125 on a support for treating cancer and a method of preparing an I-125 seed using the same. Since a method of preparing iodine according to the present invention uses an intermediate having phosphate-based, oxalate-based, or arsenate-based anions introduced thereinto, the intermediate has a substitution effect of iodine 3 to 5 times higher than that of a typically used intermediate having chlorine anions introduced thereinto. According to the substitution effect, control of a radiation dose may be possible during the manufacturing of an iodine seed and an iodine seed may be prepared within a shorter period of time. Also, since an amount of residual radioactive iodine may be decreased as a result of a large amount of adsorption, an amount of radioactive iodine (I-125) waste may be decreased, and the effect thereof may be also high environmentally.

Abstract:
A data transmission system transmitting data using a relay is provided. The relay selects a transmission terminal from a plurality of terminals connected to a base station. During a first time slot, the base station transmits base station data to the relay and the transmission terminal transmits terminal data to the relay. The relay transmits the terminal data to the base station and transmits the base station data to the transmission terminal during a second time slot.
Abstract:
Provided are a regional information extraction method, a regional information output method, and an apparatus for the same. The regional information output method includes obtaining a regional image through the processing unit, transmitting the regional image to a server through the transmitting/receiving unit, receiving regional information on a geographical position that a regional image feature extracted from the regional image represents through the transmitting/receiving unit, and outputting the regional information through the output unit, wherein the geographical position represents one feature matching to the regional image feature, which is selected from a plurality of features representing a plurality of regional images.
Abstract:
The present invention provides a method for preparing an extract fraction reinforced with ginsenoside Rg1 or Rb1 from ginseng. The method for preparing an extract fraction reinforced with ginsenoside Rg1 comprises the steps of: concentrating an alcohol extract of ginseng and then adsorbing the extract diluted in water by adding the extract to an adsorption resin; passing distilled water through the adsorption resin, then eluting and removing unadsorbed ingredients; and adding 30 to 40 v/v % alcohol to the adsorption resin to obtain an eluate. The method for preparing an extract fraction reinforced with ginsenoside Rb1 comprises the steps of: concentrating an alcohol extract of ginseng and then adsorbing the extract diluted in water by adding the extract to an adsorption resin; passing distilled water through the adsorption resin, then eluting and removing unadsorbed ingredients; and adding 50 to 80 v/v % alcohol to the adsorption resin and then eluting.
