• This book is the first to cover the research of whole aspects of international mobility to and from Taiwan of both skilled and unskilled workers. The migration of skilled workers is a field that has not been well researched, although it is becoming very important for the economic growth of newly developing countries. The "brain circulation" through which workers who return to their home country bring back technology and the business style of a developed country contributed greatly to Taiwan in the 1980s and1990s. However, according to the author's research, there is a little expectation that returnees now will contribute as in the past, as the proportion of students leaving Taiwan to study abroad is decreasing. Taiwanese companies therefore are seeking skilled human resources from developed countries in other ways. The author also found that some Taiwanese have been to China, Singapore or Japan in response to companies and universities' recruiting by offering high monetary compensation. This book clarifies those aspects of international skilled labor mobility to and from Taiwan and also analyzes the various issues regarding unskilled foreign laborers in Taiwan. There has been a gradual increase in unskilled foreign laborers, working both in industry and in domestic care in Taiwan. This book elucidates the various controversial issues arising from the increased presence of foreign laborers-for instance, the costs of employing foreign laborers, or problems related to the foreign workforce.

  • This book provides the first extensive survey of block ciphers following the Lai-Massey design paradigm. After the introduction, with historical remarks, the author structures the book into a chapter on the description of the PES, IDEA and other related ciphers, followed by a chapter on cryptanalysis of these ciphers, and another chapter on new cipher designs. The appendices include surveys of cryptographic substitution boxes and of MDS codes. This comprehensive treatment can serve as a reference source for researchers, students and practitioners.
