25일령의 한우송아지가 10일 간의 호흡기질환과 출혈성 설사의 병역을 나타내다가 폐사하였다. 이 송아지는 다른 송아지들과 비교해보았을 때 극도로 위축되어 있었다. 꼬리와 회음부의 분변 흔적은 만성설사가 지속되었음을 말해주었다. 부검시 다양한 기관(조직)에서 반상출혈이 관찰되었다. 역전사 중합효소연쇄반응에 의하여 소 바이러스성 설사병 바이러스가 진단되었다. 이 증례는 계통발생분석에서 BVDV-2a 그룹에 속하는데, 이것은 고병원성인 미국 균주890 (U18059)과 유사하다. 본 증례는 BVDV-2가 한국에서 유행하고 있다는 증거를 제공한다. 이를 통해 우리는 BVDV-2의 발생을 재확인하였다.

Batch experiments using indigenous and commercialized adventive microorganisms were performed to investigate the feasibility of the biodegradation process for the diesel contaminated soil, which was taken in US Military Camp 'Hialeah', Korea. TPH concentration of the soil was determined as 3,819 mg/kg. Four indigenous microorganisms having high TPH degradation activity were isolated from the soil and by 16S rRNA gene sequence analysis, they were identified as Arthrobacter sp., Burkholderia sp., Cupriavidus sp. and Bacillus sp.. Two kinds of commercialized solutions cultured with adventive microorganisms were also used for the experiments. Various biodegradation conditions such as the amount of microorganism, water content and the temperature were applied to decide the optimal bioavailability condition in the experiments. In the case of soils without additional microorganisms (on the natural attenuation condition), 35% of initial TPH was removed from the soil by inhabitant microorganisms in soil for 30 days. When the commercialized microorganism cultured solutions were added into the soil, their average TPH removal efficiencies were 64%, and 54%, respectively, which were higher than that without additional microorganisms. When indigenous microorganisms isolated from the contaminated soil were added into the soil, TPH removal efficiency increased up to 95% (for Bacillus sp.). According to the calculation of the average biodegradation rates for Bacillus sp., the remediation goal (87% of the removal efficiency: 500 mg/kg) for the soil would reach within 24 days. Results suggested that TPH removal efficiency of biodegradation by injecting indigenous microorganisms is better than those by injecting commercialized adventive microorganisms and only by using the natural attenuation.

The effects of algal inoculation on chemical oxygen demand (COD) and total nitrogen (TN) removal, and indigenous bacterial dynamics were investigated in municipal wastewater. Experiments were conducted with municipal wastewater inoculated with either Chlorella vulgaris AG10032, Selenastrum gracile UTEX 325, or Scenedesmus quadricauda AG 10308. C. vulgaris and S. gracile as fast growing algae in municipal wastewater, performed high COD and TN removal in contrast to Sc. quadricauda. The indigenous bacterial dynamics revealed by 16S rRNA gene amplification showed different bacterial shifts in response to different algal inoculations. The dominant bacterial genera of either algal case were characterized as heterotrophic nitrifying bacteria. Our results suggest that selection of indigenous bacteria that symbiotically interact with algal species is important for better performance of wastewater treatment.

This paper describes the role of ethnoecology in supporting tourism. We conducted a case study on the island of Bali (Indonesia), the famous tourism destination. We review the culture, nature and ecotourism prospects of Bali and then extend our discussion to examine the role of indigenous philosophies in building the destination’s image. Bali has a rich culture and natural resources that have been utilized and managed through an indigenous philosophy called Tri Hita Karana. Ethnoecology is widely applied and appreciated in the society and has produced Balinese cultural landscapes that have become significant tourism attractions. There has been a recent increase in tourist desire to explore genuine Balinese culture, so ethnoecology has a significant role in the quest to preserve and conserve such indigenous cultural landscapes. Ethnoecology is a key to ensuring and sustaining the images and authenticity of Bali Island. In this paper, we considered the landscape of rice paddies as a cultural landscape and resource for tourism. The structure and function of paddy terrace landscapes is based on the ethnoecology of Tri Hita Karana; therefore, in order to understand nature and ecotourism in Bali Island, knowledge of indigenous philosophy is indispensable. Cultural landscapes that link human and natural systems are not only places of natural beauty but also provide background information about the history of human adaptations to nature.

Climate change is considered to be one of the most serious threats and its impact is felt by the most vulnerable world's poorest countries including Bangladesh. In particular, ethnic communities, whose livelihoods depend on the use of natural resources, are likely to bear the brunt of adverse impacts. A case study was conducted in a fragile ecosystem of Lawachara national park of Bangladesh, to know the indigenous knowledge of the ethnic communities, how they adapt with the climate change impact by using indigenous knowledge. They use various IK to protect their crops from climate change impact. Thus, government should design policies which will be helpful to make them more resilience to face climate change impact.

This study investigated cases of progressively necrotizing limbs in Korean indigenous calves. The recent case (Case 1) involved a 3-month old, male calf in Jeonbuk province that presented a visibly dry form of gangrene affecting joints of the forelimbs and the hind limbs. Radiograph revealed osteoarthritis possibly resulting from pressure of disrupted joint skin, fasciae, deeper underlying musculatures and tendon. Histopathology of affected tissue showed necrotizing; severely thrombosed dilated blood vessels with rechanneling microvasculatures. The lack of substantial infectious inflammatory exudates in the vital organs and the inability to respond to antimicrobial treatment bolstered the notion that the observed thromboembolic and vascular lesion was attributed to possible vasoconstrictive effects of ergot alkaloids. Case 2: A previously encountered similar case in a 4-month old, male calf showing gangrene of hind limbs and posterior ataxia was likewise presented. These two cases were impressed as probable ergotism. Ergotism may be uncommon or underreported in Korea. Future isolation of ergot alkaloids in feeds or in pasture is highly suggested.

The main objective of this article lies in discussing dependecy issues as related to information development in NICs. The theoretical foundation was drawn from theories of 'dependency' and of 'information societies,' The main assertion of the dependency school (the more dependency, the less development) was applied for a test of the relationship between dependency on foreign scientific and technical information (STI) resources and indigenous STI development in NICs. Utilizing a case study method, this study explored the causes and results of dependency on foreign STI in a leading NIC­the Republic of Korea (ROK). First identified were the economic factors that might have influenced the ROK's dependency on foreign STI. Also investigated were the social factors that might have had associations with the R&D personnel's dependency on foreign STI. Regarding the development of information area, this study discussed general features in the process of producing, organizng, and gatekeeping indigenous STIIdentified regarding the ROK's information dependency was the R&D personnel's pattern of using foreign STI resources as well as the country's dependency on foreign STI resources. This study also discussed the socio-economic progress toward an information society in ROK for the past decades. Finally, specific linkages between the selected five variables were examined on the basis of the proposed four hypotheses.

The present study was conducted to examine the outbreak state of bovine dermatophytosis in 14 farms(4 dairy farms, 10 Korean indigenous cattle farms) in Gyeongbuk province from November 2000 to November 2001. The causative agents of dermatophytosis was identified by mycological examination. Antifungal susceptibility test of 26 isolates was performed by agar dilution method, using 5 antifungal drugs. Prevalence of bovine dermatophytosis was found to be 13.5%(90/665) in dairy cattle farms and 14.5%(220/1,520) in Korean indigenous cattle farms. The most common age at which this disease occurred was 2-12 months. This disease usually occurred from winter to spring and the occurrence subsequently decreased in the summer. But 4 Korean indigenous cattle farms with poorly hygienic status were occurred all the year round. The causative agent was identified as Trichophyton verrucosum exclusively in these case. Antifungal susceptibility test of T verrucosum (26 strains) was performed by agar dilution method, using 5 antifungal drugs including tolnaftate, griseofulvin, ketoconazole, amphotericin B and terbinafine. All isolates were highly sensitive to 5 antifungal drugs (geometric mean MICs 0.004∼0.032 $\mu\textrm{g}$/$m\ell$). The isolates were the most sensitive to especially tolnaftate.

The simultaneous biodegradation between MTBE (Gasoline additives) and BTEX (Benzene, Toluene, Ethyl-benzene, o-Xylene, m-Xylene, p-Xylene) was achieved within a competitive inter-relationship, with not only electron accepters such as nitrate, sulfate, and iron(III) without oxygen, but also with electron donors such as MTBE and BTEX. Preexisting indigenous microorganisms from a domestic sample of gasoline contaminated soil was used for a lab-scale batch test. The result of the test showed that the biodegradation rate of MTBE decreased when there was co-existing MTBE and BTEX, compared to having just MTBE present. The growth of indigenous microorganisms was not affected in the case of the MTBE treatment, whereas the growth of the microorganisms was decreased in combined MTBE and BTEX sample. This may indicate that an inhibitor related to biodegradation when BTEX and MTBE are mixed will be found. This inhibitor may be found to retard the anaerobic conditions needed for efficient breakdown of these complex carbon chain molecules in-situ. Moreover, it is also possible that an unknown competitive reaction is being imposed on the interactions between MTBE and BTEX dependent on conditions, ratios of mixture, etc.
