The ideal design of the new libraries in 21st century is explored by bench marking many libraries in developed countries. The library buildings are designed to be intelligent, multi-functional, and environmentally compatible, displaying various library treasures and promoting library materials. Thus the libraries become the community centers and tourist attractions.

With increasing demand for resources worldwide, Korea has been negotiating with resource-holding countries to achieve conservation of energy resources. Among them, Russia is the third largest resource-producing and exporting nation in the world and has several resource materials such as nickel, platinum group metals, gold, and other reserves. As a result, there is growing interest in cooperation between Korea and Russia. The aim of this article is to summarize the current status of market flow of Russian energy resources as well as Russia's economic cooperation with Korea. Notably, South Korea needs to focus on investing in overseas mines for a stable supply of rare metals. Nevertheless, securing rare metals is a major task by understanding the flow and policy direction of Russian material mines.

The data center has become an increasingly important part of most business operations. An increasing demand for computation has led to increasing industry energy consumption. Therefore, higher-than-normal rates of energy efficiency have become a core issue in the life cycle of data center. In this paper, we proposed the framework of level diagnosis for green data centre that can be used to diagnose the levels of capability maturity model. This framework contains the 5 key areas such as construction, air-conditioning, electricity, information technology, organization and indicators that can be applied as basic level diagnosis guide for green data center.

Objectives : In the Korean Pharmacopoeia 12th edition (KP 12) and the Korean Herbal Pharmacopoeia (KHP), two authentic herbal medicines are described, namely Bang-gi (Cheong-pung-deung) and Mok-bang-gi, respectively. In China, Bun-bang-gi is also used as herbal medicine. This study was conducted to develop a molecular authentication tool for distinguishing the three herbal medicine used as Bang-gi, which are Sinomeni Caulis et Rhizoma (Rhizome of Sinomenium acutum), Stephaniae Tetrandrae Radix (Root of Stephania terandra), and Cocculi Radix (Root of Cocculus trilobus). Methods : Twelve samples of three species (four samples of S. acutum, five samples of S. tetrandra, and three samples of C. trilobus) were collected from different habitats. The sequences of internal transcribed spacer (ITS) regions were obtained and comparatively analyzed to design the species-specific sequence characterized amplified region (SCAR) primers. The specificity of each pair of SCAR primers that amplified species-specific amplicon was evaluated for establishing the singleplex and multiplex PCR assay tools. Results : The singleplex SCAR markers show discriminability in C. acutum, S. tetrandra, and C. trilobus. These SCAR markers were also efficiently authenticated three species in the multiplex SCAR amplification using single PCR reaction. Furthermore, these PCR assay methods were applicable to authenticate dried herbal medicines distributed in the markets. Conclusions : The SCAR markers and PCR assay tools help discriminate the three herbal medicines used as Bang-gi at the species levels and provide a reliable genetic method to prevent the inauthentic distribution of these herbal medicines.

Objectives : The purpose of this study is to report that applying the genetic discrimination method to Pinelliae Tuber is suitable as a countermeasure for the limitations of morphological identification announced publicly in the Ministry of Food and Drug Safety(MFDS). Methods : Randomly selected fifty samples in Pinelliae Tuber imported from China were used for morphological and genetic identification. The morphological identification was applied method announced publicly by the MFDS. The traits of morphological identification were classified as Pinellia ternata, P. tripartita, Pinellia pedatisecta, and Typhonium flagelliforme, according to the formation of tuberous root and tuber morphology. The genetic identifications were conducted by Sequence Characterized Amplified Region(SCAR) marker and DNA barcoding analysis for cross-validation, respectively. SCAR marker was verified according to the presence or absence of amplicon through PCR amplification using species-specific primers. DNA barcoding analysis used sequence information of the matK region. Results : As a result of the morphological identification, 27 out of 50 samples were identified as original species 'P. ternata' of genuine 'Pinelliae Tuber', and 23 were identified as adulterant species 'P. pedatisecta'. Unlike this, the genetic identification was identified as the original species 'P. ternata' in all 50 samples in the SCAR marker and matK regional sequence analysis. Conclusions : Pinelliae Tuber of morphological mutant that can not be classified by morphological identification is imported from China. The SCAR marker would be used as accurate and efficient assays for species identification of the morphological mutant.

Objectives : Herbal medicines have been used a lot traditionally in Northeast Asia. In particular, various Apiaceae plants (Umbelliferae) are widely used for medicinal purposes among countries. However, the original species designated in each pharmacopoeia standards, are sometimes different and confuse. In this study, herbal medicines in the pharmacopoeia were analyzed for Apiaceae taxa to compare the taxonomic identity and different taxonomic opinions for each country based on their local flora and recent taxonomic studies. Methods : The scientific names of herbal medicines were analyzed origins from Pharmacopoeias of Republic of Korea, Democratic People's Republic of Korea, People's Republic of China, Taiwan, and Japan. Especially, we compared their local floras, international plant scientific name database, and recently published taxonomic studies to confirm the correct scientific name. Results : The analyzed apiaceous herbal medicines in pharmacopoeias were all 21 items and 39 taxa; the highest percentage, genus Angelica (21%) and roots including rhizomes (62%) the registered genera and medicinal parts, respectively. Eleven items were in all five country's pharmacopoeias. Four items were in more than two countries' pharmacopoeias. Six items were registered in only one pharmacopoeia. Conclusions : Our research provides necessary information, e.g., corrected scientific names of original species based on taxonomic species concepts, taxonomic reviews, and figures of medicines. These results will help in the understanding of the apiaceous taxa among the five countries' pharmacopoeias. Moreover, these extensive nomenclatural reviews of authentic apiaceous taxa will help for the next revision of Korea Pharmacopoeia.
