Tsutsugamushi disease is widely spread throughout Japan. A case of tsutsugamushi disease was seen in October, 1996. A 64-year-old male developed typical symptons of tsutsugamushi disease with Rickettsia tsutsugamushi, after he returned to Japan from Cheju Island, Korea. Not only in Japan but also in other Asian countries including Korea, China, Taiwan, and Thailand, tsutsugamushi disease is one of the most important rickettsial diseases carried by ticks or mites.If a traveller returning from an Asian country has symptons such as high fever, skin eruption, and lymphadenitis, we should susupect that he is suffering from tsutsugamushi disease and should search if he has an eschar on any area of his body. We should not forget that tsutsugamushi disease is an imported disease. Patients of tsutsugamushi disease often have hematological disorders. They are sometimes referred to the hematological section of the hospital. Hematologists should be familiar with this disease.

The tumor extension of T4 cases of upper gum carcinoma (UG-Ca) is clinically similar to T2 cases of maxillary sinus carcinoma (NIS-Ca). However, the prognosis of the former is remarkably unfavorable compared with the latter. A comparative study between 16 cases of UG-Ca (T4) and 14 cases of MS-Ca (T2) was undertaken in order to assess the difference in their prognosis.<BR>The 5 year accumulative survival rate of UG-Ca (T4) was 36.5% and MS-Ca (T2) was 92.3%. While the control rate of the primary lesion after initial therapy, the former was 50% and the latter was 78.6%. As for the rat of cervical metastases noted clinically, it was 75% and 35.7% respectively. Bilateral cervical metastases was noted in 6 cases of UG-Ca (T4) and none in MS-Ca (T2). With respect to the 5 year accumulative survival rate of the cases with pathologically confirmed nodal involvement, it was 0% for UG-Ca (T4) but MS-Ca (T2) was 66.7%.<BR>The unfavorable prognosis for UG-Ca (T4) cases was attributed to failure to control primary and cervical metastases. Therefore, it is necessary to reexamine the margin of the primary resection and the timing for carrying out RND.

本稿では,コグニティブ無線に適用可能な無線ビームスイッチング方式について,無線周波数利用効率の観点から,Web閲覧時のレスポンスタイムを評価関数として検討を行った.スイッチング方式とは,基地局間のリンクにおいて,1つの周波数帯域を周波数分割するのではなく,全帯域を対向する基地局間で時分割で共用する方法である.ネットワーク構成は,単純なトポロジーから2段接続,3ブランチの場合も検討を行った.その結果,ビームスイッチングを行うと,固定割当よりもレスポンス特性が良くなり,ユーザの周波数利用効率の観点からは有用であることが明らかになった.ビームスイッチングアンテナの開発も平行して行っており,通信装置も含めたシステム全体の特性についても今後検討を行っていく.
