Vietnam is endowed with multiform new and renewable energy resources. However, potential of new and renewable resources in Vietnam has not been completely assessed. Although the Government has embarked several programs to expand the use of these resources, the share of new and renewable energy in total commercial energy is still insignificant. The purpose of this study is to summarize potential and current development status as well as the prospect of new and renewable energy. Identification of barriers that are the hindrances in the development of new and renewable energy would suggest measures to future commercialization of new and renewable energy.

Bovine genome samples were collected from meat of three different beef breeds (Hanwoo, Holstein and imported beef breed) that are commercially merchandized in Korean beef market. Operon B (OPB)-kits were used as random primers (3, 7, 10, 11, 12, 14) in random amplified polymorphic DNA (RAPD) method on whole genome. Each primer provided characteristic bands that were highly polymorphic. Each single primer could provide relatively efficient polymorphic band patterns among breeds. However, use of two or more primers in combination is recommended to improve resolution of experiments with higher molecular weight bands of DNA. In our experiments, OPB-11 resolved well between beef cattle breeds and Holstein. And OPB-7, 12 and 14 could be combined with OPB-11 to identify Hanwoo beef from the other two kinds of beef.

We used a non-invasive technique with microsatellite primers to investigate genetic variation among Eurasian otters Lutra lutra in eastern South Korea. We collected twenty two otter spraints in January and six in August 2008. We used spraints from five dead otters from five different river systems for the present genetic analysis. We extracted DNA from 20 spraints from the January sample. Ten microsatellite primers (Lut435, Lut453, Lut457, Lut604, Lut615, Lut701, Lut715, Lut717, Lut733, and Lut832) for Eurasian otters were tested, and four loci were successfully amplified for further analyses. The results of genotyping the otter population with microsatellite loci lead to the identification of 9 individuals from the Ungokcheon Stream. The Ungokcheon population also showed a genetic structure represented by the Hardy-Weinberg equilibrium.

The purpose of this study is to examine the characters and sustainability of built heritage featured in the eight-scenery listings of Gyeonggi municipalities in South Korea. Eight scenery is a place marketing medium that reflects the community's appreciation of the selected resources. For a research method, we utilize framework analysis to understand the cultural resources in three categories: heritage value identification, preservation, and dissemination. Primary sources for data collection include the chosen eleven cities' eight-scenery webpages, the National Cultural Heritage Portal, and articles about the built heritage resources included in the eight scenery. The results of this study show the public's acknowledgment of diverse built heritage, from prestigious monuments to local heritage interpretations, and various preservation and public program development approaches. The conclusion discusses the research findings regarding historic preservation, sustainable development, and place marketing.

Large earthquakes with (M_W > ~ 6) result in ground shaking, surface ruptures, and permanent deformation with displacement. The earthquakes would damage important facilities and infrastructure such as large industrial establishments, nuclear power plants, and waste disposal sites. In particular, earthquake ruptures associated with large earthquakes can affect geological and engineered barriers such as deep geological repositories that are used for storing hazardous radioactive wastes. Earthquake-driven faults and surface ruptures exhibit various fault zone structural characteristics such as direction of earthquake propagation and rupture and asymmetric displacement patterns. Therefore, estimating the respect distances and hazardous areas has been challenging. We propose that considering multiple parameters, such as fault types, distribution, scale, activity, linkage patterns, damage zones, and respect distances, enable accurate identification of the sites for deep geological repositories and important facilities. This information would enable earthquake hazard assessment and lower earthquake-resulted hazards in potential earthquake-prone areas.

The spionid polychaete Scolelepis geniculata, originally described in Japan, is newly recorded in the Korean fauna. Specimens collected from the eastern and southern coasts of Korea between May 1999 and October 2002, stored in the invertebrate collection of the National Institute of Biological Resources, were examined based on their morphology. Scolelepis geniculata is morphologically most similar to S. yamaguchii from Japan and Korea but is distinguished by having branchiae separated from the notopodial lamellae in posterior chaetigers and notopodial prechaetal lamellae digitiform in anterior chaetigers instead of subtriangular. A detailed morphological description of S. geniculate, and an amended identification key to all Korean Scolelepis species is provided.

The fungus genus Sclerotinia contains a number of important plant pathogens. Vegetable growers in our country are probably most familiar with Sclerotinia sclerotiorum, the causes of sclerotinia rot on crisphead lettuce. S. sclerotiorum has a wide host range which can include lettuce as well as crops such as broccoli, cabbage, carrots, celery, beans, peppers, potatoes, stocks, and tomato. Some fungicides, including benomyl, are effective in some crops, but not all. So, we isolated a antagonistic bacteria that are active on sclerotinia rot caused by S. sclerotiorum and that can be used to control it. About 702 strains had been isolated from soil around plant roots in the field. Ten strains showed strong antifungal activity against S. sclerotiorum. In pot test for antagonistic activity, A-7 strain showed high control value against the pathogen when compared with others. The strain was, therefore, selected as a biocontrol candidate against sclerotinia rot and its biochemical properties and 16S rDNA sequence was analyzed. The A-7 strain was highly related to Bacillus subtilis and B. amyloliquefaciens. To confirm precise identification, we had performed gyr A gene sequences analysis. Its sequence had 96% similarity with B. amyloliquefaciens. Consequently, the isolate was identified as B. amyloliquefaciens A-7.

Objectives : Due to the morphological similarity and frequent occurrence of intermediate forms as well as morphological variations of aerial part, the correct identification between Rhei Radix et Rhizoma and Rhei Undulatai Rhizoma is very difficult. To develop a reliable method for correct identification and improving the quality standards of Rhei Radix et Rhizoma and Rhei Undulatai Rhizoma, we analyzed RAPD and developed SCAR marker. Methods : To amplify target DNA at the genomic level, 32 Operon 10-mer random primers were applied with four Rheum species, R. officinale, R. palmatum, R. tanguticum and R. undulatum. The nucleotide sequences were determined and species-specific primers were prepared depending on the species-specific RAPD amplicons after subcloned into the pGEM-Teasy vector. To develop the SCAR markers, species-specific PCR amplification and multiplex-PCR were carried out using the single species-specific primer pairs and combinations of them, respectively. Results : We used RAPD analysis of four Rheum plant species to obtain several species-specific RAPD amplicons. From nucleotide sequences of these RAPD amplicons, we developed two SCAR markers that amplified 314 bp and 390 bp DNA fragments in only R. undulatum but not in R. officinale, R. palmatum, R. tanguticum and R. undulatum, for distinguishing Rhei Undulatai Rhizoma and Rhei Radix et Rhizoma. Furthermore, we established SCAR markers for the simultaneous discrimination of the three species within a single reaction by using multiplex-PCR. Conclusions : These genetic markers can be used for the efficient discrimination of plants species and commercial herbal medicines between Rhei Undulatai Rhizoma and Rhei Radix et Rhizoma, to ultimately prevent indiscriminate distribution and prescription of these herbal medicines.

A single specimen of the genus Sillago, collected from Gwangyang, Korea, in May 2009, is characterized by XI first dorsal fin spines, 3 or 4 rows of melanophore pattern along the second dorsal fin membrane, and a darkish posterior margin of the caudal fin. Our specimen was identified as Sillago sinica reported as a new species; this identification is confirmed by mitochondrial DNA cytochrome oxidase subunit I sequences, which show that our specimen corresponds to S. sinica (d=0.000) and differs from the congeneric species Sillago parvisquamis (d=0.170). Comparisons of Korean specimens previously reported as S. parvisquamis with specimens of S. sinica show that the S. parvisquamis specimens are actually S. sinica. We propose the new Korean name "buk-bang-jeom-bo-ri-myeol" for S. sinica.
