Repeated interaction between a terrorist group and a target government is analyzed in a game-theoretic model. The analysis identifies a dynamic inconsistency problem, which forces the government to under-invest in defensive measures while over-investing in offensive measures. Policy implications are discussed in light of recent US counterterrorism experience. It is shown that governments may resolve the problem by delegating the authority over defensive measures to an independent agency.

Make-or-buy decision of a durable-good monopolist is analyzed when the quality of an existing product may be improved through investment. Outsourcing generates a hold-up problem which leads to underinvestment in product development. But the very inefficiency in investment also helps the monopolist's initial sales as it makes the existing product less likely to become obsolete. Outsourcing is shown to outperform vertical integration when the value of the improvement is relatively small. The strategic motive for outsourcing identified in the analysis sheds new light on the "core competence" argument commonly used in management literature.

Korea's technological achievement in the thin film transistor liquid crystal display (TFT-LCD) industry became possible primarily through a catch-up strategy in technological development. Through qualitative and quantitative analyses of the Korean TFT-LCD industry's knowledge management, the researchers highlight the strategies that key Korean firms utilized to enable a successful technological catch-up. On a national level, patent citation information is analyzed to evaluate the Korean industry's technological knowledge position compared to other Asian countries. Results from this analysis indicate that Korea plays a central role within the knowledge network, as evidenced by the highest centrality value. On a firm level, Samsung and LG Display are investigated in the areas of technological development and manufacturing strategies. Samsung and LG Display show strength in the technological specialization of devices' arrangements/optical operation and arrangement/circuits of control indicating devices. In addition, these two firms show more diversification to allow for new business opportunities. By integrating quantitative and qualitative methods to analyze the TFT-LCD industry on national and firm levels, this research demonstrates the industry's trajectory with depth and precision. In addition, this study contributes a meaningful strengthening of analysis methods in technological knowledge management and provides successful management factors for new latecomers in the industry.

AbstractAlthough advances in cancer treatment and early diagnosis have significantly improved cancer survival rates, cancer therapies can cause serious side effects, including ovarian failure and infertility, in women of reproductive age. Infertility following cancer treatment can have significant adverse effects on the quality of life. However, established methods for fertility preservation, including embryo or oocyte cryopreservation, are not always suitable for female cancer patients because of complicated individual conditions and treatment methods. Ovarian tissue cryopreservation and transplantation is a promising option for fertility preservation in pre-pubertal girls and adult patients with cancer who require immediate treatment, or who are not eligible to undergo ovarian stimulation. This review introduces various methods and strategies to improve ovarian tissue cryopreservation and transplantation outcomes, to help patients and clinicians choose the best option when considering the potential complexity of a patient's situation. Effective multidisciplinary oncofertility strategies, involving the inclusion of a highly skilled and experienced oncofertility team that considers cryopreservation methods, thawing processes and devices, surgical procedures for transplantation, and advances in technologies, are necessary to provide high-quality care to a cancer patient.
