  • This study was conducted to compare protected areas of South and North Korea based on international conservation criteria and recommend new fundamental directions for nature conservation policy. International conservation criteria used by this research were the 1994 IUCN protected area categories, composed of 6 management categories. Despite a variety of types and names of protected areas created by different domestic legislations, South Korea was revealed to have only two types of protected areas, Category IV and V, indicating the significant lack of ecological diversity and representativeness in its protected area system. Shockingly, there are no national parks meeting IUCN criteria in South Korea. On the other hand, North Korea has three IUCN Categories of II, III, IV and thus more balanced and ecologically representative protected area network than South Korea. Especially, North Korea maintains 9 national parks to be officially recognized by IUCN and UN. However, both South and North Korea should make sincere effort to have new and well-designed protected area system including all IUCN Categories I -Ⅵ and particularly a minimum area in the stricter protected area categories.

  • In recent years, a new approach to cyber security, called the moving target defense, has emerged as a potential solution to the challenge of static systems. In this paper, we design a protected server network with a large number of decoys to anonymize the protected servers that dynamically mutate their IP address and port numbers according to Hidden Tunnel Networking, which is a network-based moving target defense scheme. In the network, a protected server is one-to-one mapped to a decoy-bed that generates a number of decoys, and the decoys share the same IP address pool with the protected server. First, the protected server network supports mutating the IP address and port numbers of the protected server very frequently regardless of the number of decoys. Second, it provides independence of the decoy-bed configuration. Third, it allows the protected servers to freely change their IP address pool. Lastly, it can reduce the possibility that an attacker will reuse the discovered attributes of a protected server in previous scanning. We believe that applying Hidden Tunnel Networking to protected servers in the proposed network can significantly reduce the probability of the protected servers being identified and compromised by attackers through deploying a large number of decoys.

  • This study presents an integrated evaluation method to assess the level of achievement of quantitative expansion goals and qualitative improvement goals based on the Aichi Biodiversity Target 11 for quantitatively expanding and qualitatively improving national protected areas. The quantitative evaluation indicators for national protected areas are the percentage of terrestrial and inland water areas protected and the percentage of marine and coastal areas protected. The quantitative evaluation indicators for national protected areas are selected as 6 indicators: 1) ecologically important areas, 2) ecological representativeness, 3) management effectiveness, 4) connectivity, 5) social equity and 6) integration. Ecologically important areas are an indicator which evaluates how many areas of particular importance for biodiversity and ecosystem services are included in national protected areas. Ecological representativeness is to assess how well national protected areas represent the ecosystem. Management effectiveness is an indicator which evaluates how effectively national protected areas are conserved and managed, and connectivity is an indicator to assess how well national protected areas are connected. Social equity is evaluating how equitably national protected areas are managed and the integration is assessing how much national protected areas are integrated into the wilder landscape and seascape. This study is significant in that it provides a perspective of qualitative improvement as well as quantitative expansion of national protected areas for biodiversity conservation through accurately understanding Aichi Biodiversity Target 11.

  • This study aimed at comparing protected areas of Korea and Australia based on international conservation criteria by IUCN and analyzing what we need to improve for future management of protected areas of Korea. The registration status of protected areas of Korea listed on IUCN were 11 places in the Ia, 17 in II, 7 in IV, 7 in V; in total 42 places were recorded. However, the lists were missing many important areas. In Korea, we have only 4 protected area categories out of 6 indicating ecological diversity and management in its protected area system are insufficient. On the other hand, 9340 protected areas of Australia were listed on IUCN and evenly distributed in the total of six categories. Therefore, Korea should investigate measures for system establishment which ensures the diversity and indicative of our natural ecosystems and establish balanced system of protected areas including all IUCN categories I-VI through revaluation of natural, cultural, economic and social conditions and the needs.

  • The objectives of the present study were to investigate whether or not dietary lysine addition could improve N balance of female Japanese Saanen goats at 15 to 32 months of age, weighing 31 to 40 kg, fed on a wheat bran-hay cube diet supplemented with methionine, and whether or not ruminally protected lysine supplementation could give as good an N balance performance as lysine in the presence of ruminally protected methionine when given orally to the goats. It was considered from changes in N balance and N utilization that the first-and second-limiting amino acids in the diet were methionine and lysine respectively, under the present experimental conditions. The ruminally protected lysine in addition to the ruminally protected methionine gave no improvement in N balance and N utilization compared with the ruminally protected methionine alone, suggesting that the ruminally protected lysine used in the present study was not effectively utilized by the goats.
