We develop an adaptive hot-spot operating scheme(AHOS) to mitigate the negative effects from the nonuniform distribution of user location and the variation in the mixture of QoS requirements in OFDMA downlink systems. The base station in a macrocell can control the operation of picocells within the cell, and turns on or off according to the changes in the estimated user outage probability and the AHOS gain parameter. With the computer simulation, the AHOS has been proved to maximize the system throughput while maintaining the QoS outage probability very low under various system scenarios.

Electrolyte matrix fabrication process can be classifed as hot pressing, tape casting, callendering, electrophoretic deposition. however, these have limits in practice. Hot pressing is cumbersome method, because of careful heating and cooling. Furthermore, the perfected tile is so fragile that it is difficult to fit in a cell. Therefore this method is not adequate for mass production of the electrolyte matrix. Using electrophoretic deposition method, a very thin matrix can be made, but many attempts of the electrolyte embeding were found to be failure. Tape casting and callendering methods are employed in most of the matrix fabrication for the present. But these methods require lots of water as a solvent, so that coating of the LiAlO sub(2) with electrolyte is difficult. Recently, hot roll milling method has been developed and the perfected matrix was proved to be free from crack. The method, however, needs a roller to make a matrix and a perfected matrix is carefully striped off from the cooled roller. Therefore, this method requires a long time due to the cooling process. The author proposes a cold rolling process. On this method, heated slurry of the LiAlO sub(2) mixed with binder, is rolled with a cold roller. The heated slurry dose not adhere to the roller, since contacted hot slurry is rapidly solidified. Therefore fabrication speed is increased, without getting rid of merits of the hot rolling process.

A literature study on cancer therapy of warm-hot oriental medicine was done, and the results were as follows. 1. In oriental medicine, oncogens are six exopathogens, seven modes of emotion, overwork, pathogenic factors, and especially related with pathologic cold situation. 2. There are many capillaries in tuomr, and because temperature of inner space of tumor is higher than normal organization. Tumor cell has a character which is weak for high temperature. 3. Warm-hot herb drugs have effects of dissipating mass, warming kidney to reinforce yang and dispering, so it has a function of suppressing tumor as well as improving immunity in cancer therapy. 4. In traditional medical books, main prescriptions of cancer therapy are xinzhiyinyanggongjiwan(新製陰陽攻積丸), qianjinxiaoshiwan(千金硝石丸), feiqiwan(肥氣丸), xibenwan(息賁丸), fuliangwan(伏梁丸), beiqiwan, bentunwan(賁豚丸), zengsunwujiwan(增損五積丸), and these are composed of warm-hot herb drugs. 5. In current, the study of warm-hot drugs is progressed in immunological capacity, anti-tumor activity, stimulating bone marrow and regulating hormone secretion. It will be expected that advanced study of these must be accomplished in cancer patients.
