We examined a case in which laparoscopic surgery was performed before the first laparotomy for ovarian cancer unexpectedly, and ovarian cancer metastasis occurred at the port site and the circumference. A 48-year-old woman with left ovarian cancer was scheduled to undergo surgery, but acute cholecystitis developed, and an emergency laparoscopic cholecystectomy was performed. On the fifteenth postoperative day, because of acute abdomen and suspected ovarian tumor rupture, total hysterectomy, bilateral salpingo-oophorectomy, and omental biopsy laparotomy were performed. The postoperative pathological diagnosis was endometrial carcinoma with clear cell carcinoma, FIGO stage IC 2 (pT1c2pNXpM0). On the fifty-sixth day after laparotomy, a 10 mm sized tumor was found under the skin at the port site. Computed tomography (CT) revealed a mass in the right upper quadrant of the abdomen, a mass in the porta hepatis, the S4/5 region of the liver, and enlarged lymph nodes in the left external iliac region. It was considered that the ovarian cancer rapidly revived, and debulking surgery was performed. Recurrence of ovarian carcinoma was confirmed by pathological results, including a port-site mass. It is not a typical dissemination of ovarian cancer, and laparoscopic surgery might have resulted in metastasis. It should be prudent for the adaptation of laparoscopic surgery, even if it is an operation for a benign disease in a case, in which ovarian cancer is suspected.

Evasive Malware via Identifier Implanting [chapter]

To cope with the increasing number of malware attacks that organizations face, anti-malware appliances and sandboxes have become an integral security defense. In particular, appliances have become the de facto standard in the fight against targeted attacks. Yet recent incidents have demonstrated that malware can effectively detect and thus evade sandboxes, resulting in an ongoing arms race between sandbox developers and malware authors. We show how attackers can escape this arms race with what
more » ... e call customized malware, i.e., malware that only exposes its malicious behavior on a targeted system. We present a web-based reconnaissance strategy, where an actor leaves marks on the target system such that the customized malware can recognize this particular system in a later stage, and only then exposes its malicious behavior. We propose to implant identifiers into the target system, such as unique entries in the browser history, cache, cookies, or the DNS stub resolver cache. We then prototype a customized malware that searches for these implants on the executing environment and denies execution if implants do not exist as expected. This way, sandboxes can be evaded without the need to detect artifacts that witness the existence of sandboxes or a real system environment. Our results show that this prototype remains undetected on commercial malware security appliances, while only exposing its real behavior on the targeted system. To defend against this novel attack, we discuss countermeasures and a responsible disclosure process to allow appliances vendors to prepare for such attacks.

An innovative column attachment ventilation (CAV) was proposed for heating, ventilating and air-conditioning (HVAC) systems and its performance was evaluated through experimental investigation and numerical modeling. Airflow pattern, air temperature distribution, air diffusion performance index (ADPI), predicted mean vote (PMV), and draught rate (DR), were used as the performance indicators to investigate the air distribution performance. The ventilation effectiveness for heat removal in the

The results showed that the discharged air from the linear slot diffuser can attach to the column and enter into the occupied zone creating air lake phenomenon. The airflow spread over the floor in a radial pattern behaved as a stratified air distribution like displacement ventilation (DV), providing good air quality and comfort level for occupants. Moreover, the heat removal effectiveness in the CAV was found to be higher than in the MV, i.e. 1.32 in the C-CAV and 1.29 in the S-CAV modes. The column attachment ventilation can achieve thermal comfort in the occupied zone without local discomfort caused by high vertical temperature difference and draught, and this ventilation strategy could be expected as a new and efficient air distribution pattern for different HVAC applications.
