    迷惑メール対策には,メール内容から迷惑メールを判定する手法と送信者情報を用いる手法があげられる.送信者情報の送信元IPアドレスや送信者のドメイン名から受け取るべきメールかを判断できれば,判定のための処理負荷の高いメール内容によるメールフィルタの処理を軽減させることができる.本論文では,送信ドメイン認証技術を利用することで転送メールの送信元を特定し,メール転送元が受け取るべき送信元であることを示し,メール転送元を含めた正規メール送信元を収集することで許可リストを構築する手法を提案する.この手法を含めた,送信者レピュテーションの構築手法を提案し,実際に受信したメールの記録を利用して送信者レピュテーションを構築し,適用することで送信者レピュテーションの構築手法の有効性を示す.Anti-spam measures include methods for determining unsolicited mail from the mail content and methods for using sender information. If it can be determined from the sender\u27s IP address of sender information and the sender\u27s domain name whether the email should be received, it is possible to reduce the processing of the email filter by the email content that has a high processing load for the determination. In this research, we identify senders of forwarded emails by using sender domain authentication technology, show that the senders should receive the emails, and collect the legitimate email senders including mail forwarders. We propose a method to build a permission list in. We propose a sender reputation construction method that includes this method, construct the sender reputation using the records of the actually received emails, and show the effectiveness of the sender reputation construction method

    Early Mobilization after Free-flap Transfer to the Lower Extremities: Preferential Use of Flow-through Anastomosis

    Background: Prolonged bed rest and elevation have traditionally been considered necessary after free-flap transfer to the lower extremities. In this retrospective study, we tried to mobilize patients early after free-flap transfer to the lower extremity by means of flow-through anastomosis for both arteries and veins. Methods: This study included 13 consecutive patients who underwent immediate free-flap transfer after wide resection of soft-tissue tumors of the lower extremity from March 2012 through July 2013. The defects were above the knee in 5 patients and below the knee in 8 patients. In all patients, flow-through anastomosis was used for both arteries and veins. The patients were mobilized starting on the first postoperative day, and their activities of daily life were gradually expanded, depending on the wound conditions. Postoperative complications and the progression of their activities of daily life were investigated retrospectively. Results: No anastomotic failure or take back occurred. Partial flap necrosis occurred in 1 patient because of a poor perforator but was unrelated to early mobilization. All patients could move to wheelchairs on the first postoperative day. Within 1 week, 12 of 13 patients could start dangling and 10 of 13 patients could start ambulating. Conclusions: This study demonstrates that early mobilization after free-flap transfer to the lower extremity is made possible by flow-through anastomosis for both arteries and veins. Flow-through flaps have stable circulation from the acute phase and can tolerate early dangling and ambulation
