  • Korean Peninsula Flora Database (KPF database), developed by T.B. Lee Herbarium of Seoul National University comprises ca. 65,000 accessions of vascular plants collected from Korean peninsula from 1850 to 1945. Among these, material from North Korea (Democratic People's Republic of Korea) is represented with ca. 33,000 accessions. The largest part of this material [ca. 4287 accessions (13%) from North Korea] originates from five Japanese and one American collectors, such as Imai, Hanjiro, Mills, Ralph Garfield, Furumi, Masatomi, Nomura, Naohiko, Saito, Tatsumoto, and Okuyama, Shunki from 1909 to 1942. These data are the third largest holding (13%) of North Korean collections after Komarov, V.L and Nakai, T. A part of scientific report about the results of these expeditions had been published before, but the present publication set it sights on giving a first overview of the itineraries and the materials collected by five collectors in North Korea. Among these, Saito has by far the largest collection with 1,730 specimens, followed by five collectors in order with 1,067, 532, 510, 368 and 370 accessions by Mills, Nomura, Okuyama, Furumi, and Imai respectively.

  • Many problems are arisen due to the weakness in the security and invasion to privacy by malicious attacker or internal users while various data services are available in ubiquitous network environment. The matter of controlling security for various contents and large capacity of data has appeared as an important issue to solve this problem. The allocation methods of Ito, Saito and Nishizeki based on traditional polynomial require all shares to restore the secret information shared. On the contrary, the secret information can be restored if the shares beyond the threshold value is collected. In addition, it has the effect of distributed DBMS operation which distributes and restores the data, especially the flexibility in realization by using parameters t,v,k in combinatorial design which has regularity in DB server and share selection. This paper discuss the construction of new share allocation method and data distribution/storage management with the application of matrix structure of t-(v,k,1) design for allocating share when using secret sharing in management scheme to solve the matter of allocating share.
