Abstract: The present invention relates to a pharmaceutical composition for diagnosing and treating prostate cancer, capable of targeting PSMA, and a compound provided by one aspect of the present invention has a glutamine-urea-lysine compound to which a radioactive metal-coupled chelator is structurally coupled and to which an aryl group that can additionally bind to PSMA protein is coupled. Coupling between the glutamine-urea-lysine compound and the chelator includes a polar spacer so as to serve the role of reducing in vivo nonspecific coupling and exhibit an effect of being rapidly removed from vital organs, but not from prostate cancer. These characteristics lower the radiation exposure, which is caused by a therapeutic radioisotope-coupled compound, to normal tissue and organs, and thus reduce side effects. In addition, a compound that contains a phenyl group having a coupling force with albumin has an increased residence time in the blood, thereby becoming more accumulated in prostate cancer.

Abstract: A backlight unit suitable for use as an illuminator for liquid crystal display devices. The backlight unit comprises a glass light guide plate with a glass sheet including a first glass surface comprising a plurality of channels separated by peaks and arranged periodically therein, and a plurality of light emitting diodes arranged in an array along at least one edge surface of the glass sheet.

Abstract: Method and apparatus for interactively changing an EEPROM data of a video cassette tape recorder. A service menu picture of a service mode is displayed on a television screen if the service mode is selected in response to a first remote controller input. An EEPROM data change menu picture is displayed on the television screen if an EEPROM data change mode in the service menu picture is selected in response to a second remote controller input. A characteristic value selection picture of a driving apparatus for projecting lenses of a three dimensional projector selected item is displayed on the television screen if the item in the EEPROM data change menu picture is selected in response to a third remote controller input. Then, EEPROM data are changed to a selected characteristic value if the characteristic value in the characteristic value selection picture is selected in response to a fourth remote controller input.

Abstract: Method and apparatus for interactively checking an error of a video cassette tape recorder. Whether or not a service mode is selected by a first remote controller input is checked. A menu picture is displayed on a television screen if the service mode is selected. Whether or not an error check mode in the menu picture is selected by a second remote controller input is checked, and then an error check mode picture is displayed on the television screen if the error check mode is selected. A first check operation is performed about a reproducing system and a first check result is stored into a memory, and an insertion request picture which requests an insertion of a test video cassette is displayed on the television screen when the first check operation is finished. A second check operation is performed about the reproducing system while a reproducing is going on after the test video cassette is inserted and a second check result is stored into the memory.
