Volume 3 deals with the relationships between firms in relation to media products. It examines issues of media concentration in the fields of music, the press, and broadcasting as well as related topics in copyright law, competition law, brand-name law, and domain rights, including protection of work titles, seals, and logos.

Technical improvements over the past twenty years have made endos copy the procedure of choice for examination of the hollow organs of the genitourinary and gastrointestinal tracts. The development of electro surgical techniques, laser technology, injection therapy, and a wide variety of other modalities now allow the endoscopist to treat many problems that in the past required open surgery. The simultaneous development of transcutaneous abdominal sonography has had an equally dramatic impact on the practice of gastrointestinal and geni tourinary surgery. The marriage of these proven technologies, known as endoscopic sonography, provides an exciting new modality that promises to further revolutionize the diagnosis and management of many intraabdominal diseases. Endoscopic sonography opens new frontiers by overcoming the primary limitations of its parent technologies. Fiberoptic endoscopy is limited by the inability to see beyond the luminal surface, this is particularly important when considering neoplastic disease because depth of wall invasion is a key factor in determining treatment. The limiting factor in transcutaneous sonography is the distance between the transducer and the target organ. With endoscopic sonography, the transducer is placed in close proximity to the target organ. This allows the use of high frequency waves (greater than 5 MHz), which provide better tissue resolution and eliminates the image distortion caused by overlying structures.

It is now more than 40 years since Drs. Wild and Reid published their first experience with rectal ultrasonography from the Surgery Department at the University of Minnesota. Professor Owen H. Wangen steen, in whose laboratory the studies were carried out, recognized at that time the need for early detection in the treatment of cancer. Technical improvements over the past 20 years have made endoscopy the procedure of choice for examination of the hollow organs of the genital, urinary and gastrointestinal tracts. The simultaneous development of endosonography has had an equally dramatic impact on the practice of medicine and surgery. The technology has been demonstrated to be helpful in both benign and malignant conditions. One of the so-called benign conditions of the anorectum is fistula-in-ano. Fistula surgery has always relied on excellent anatomic delineation of the intramuscular tracts. There is hope that adaptation of ultrasonographic technology will aid in the surgical management of this malady. Clearly, rectal ultrasonography has considerable potential in the management of rectal carcinoma. Accuracy rates in the range of 90% for the depth of neoplastic invasion have been reported. This ability for accurate assessment will undoubtedly lead to a better definition of the population of patients that can be managed by local therapeutic means.

This book provides a comprehensive guide to the EU Trade Mark Regulation (EUTMR). The book comments in detail on all provisions of the EUTMR, taking into account the case law of the European Court of Justice and domestic courts as EU Trade Mark courts. It then goes on to look at the decisions of the General Court, the Boards of Appeal and the first instance practice of the EUIPO.

Von der Krise lernen. Corona zeigt uns, was wir sonst nicht sehen wurden. Wer sind die Verlierer und Gewinner? U.a. Restaurants, Hotels, Kulturschaffende und Reiseveranstalter kampfen ums (wirtschaftliche) UEberleben. Menschen, die physisch und psychisch krank werden. Wir suchen Nahe und mussen Abstand einhalten. Wo sind die Fehler im System, z.B. Fehlende Notfallvorrate fur Masken, Schutzkleidung Fehlende Digitalisierung in Schulen und Gesundheitsamtern Was koennen wir selber anders machen, z.B. weniger und hochwertigeres Fleisch essen = bessere Arbeitsbedingungen in fleischverarbeitenden Betrieben = weniger Corona-Masseninfektionen Wissenschaftliche Erkenntnisse richtig verstehen und anwenden. Akzeptieren, dass Wissenschaft ein lernendes System ist, das pruft, verwirft und bestatigt. Selbstverstandlichkeiten, die wir vielleicht nicht genug zu schatzen wussten, z.B. Offene Grenzen, unbeschwertes Reisen Menschliche Nahe, Feiern Wie gehen wir mit Globalisierung um? Es ist kaum zu verhindern, dass aus einer begrenzten Epidemie erneut eine globale Pandemie wird. Was haben wir gelernt? Was koennen und mussen wir zukunftig besser machen? Corona zwingt uns zu AEnderungen. Das nachste Virus kommt bestimmt.
