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.

The purpose of this study is to investigate the management of Indigenous fermented foods during the period of economic development starting from 1960 until now, and to specify their correlation, while paying special concern to the variables of social change such as the increase of people's income, ceaseless migration of population, change in the family structure, heightening up of the educational level of women and the resulting increase of chances for getting employment, all of which may affect the management of Indigenous fermerted foods in korean families. The result is as follows. Basic seasonings and dishes such as soy bean sauce, red pepper paste, pickled seafoods, and Kimchi, are inclined to be bought as readymade products or provided by relatives in case of many nuclear families rather than made at home, which is a traditional way of home life. However, Kimchi and basic sauces or redpepper paste still show high rate of being made at home. Social variables which affect such tendency are the number of family members, the age and educational level of housewife, and the type of residence.

Bovine abdominal fat necrosis (lipomatosis) is relatively common disorder in adult Korean indigenous cattle. Thirteen Korean indigenous cattle with bovine lipomatosis and five clinically healthy cattle were selected and serum biochemical profiles were analyzed. Serum free fatty acids level was significantly high, while total cholesterol, serum albumin and total calcium levels were significantly low in bovine lipomatosis group. In a case of necropsy, saponificated adipose masses surrounding colon was observed and hepatic fatty degeneration and fat deposition in the renal tubules were found in a histopathologic examination. These findings indicate that affected cattle have a predisposition to deposit more fat into adipose tissue than normal cattle. Such abnormalities might lead to the development of abdominal fat necrosis with fibroplasia and possibly compress the intestines and urinary organs.

The digitization of traditional medical knowledge in Tanzania will greatly enhance its preservation and dissemination. This is especially important given the challenges facing the current methods of preserving and managing such knowledge. This study presents the requirements engineering approaches and requirements for a web-mobile application that would successfully digitize indigenous knowledge of phytomedicine and relevant practitioners licensing and registration processes. To establish the requirements of such a digital system application, the study sought the opinion of 224 stakeholders whose suggestions were used to analyze and model the requirements for designing such a web-mobile tool. The study was carried out in Arusha, Kagera and Dar es Salaam regions of Tanzania which involved ethnobotanical researchers, herb practitioners, curators from herbaria and registrar officers from Traditional and Alternatives Health Practice Council. Structured interview, survey, observation and document review were employed to find out the basic functional and non-functional requirements for possible designing and implementation a web-mobile application that would digitize indigenous knowledge of medicinal plants. The requirements were modelled using the use case and context diagrams. Finally, the study came up with a list of items for both functional and non-functional requirements that can be used as guidelines to develop a web-mobile application that will capture and document traditional medical knowledge of medicinal plants in Tanzania and, enabling relevant authorities to regulate and manage stakeholders.

This paper presents how Korea succeeded in developing an indigenous nuclear power plant model over fifty years. Long-lasting national R&D for technical progress and the Korean government for managerial process were the two pillars in the build-up of indigenous Nuclear Power Plant (NPP) technological capabilities. The concept of technological capabilities is used to examine its evolutionary process with a qualitative and longitudinal approach. The government had a developing country ambition to formulate a strategic plan for technical self-reliance on nuclear power plant while establishing the country’s institutions and organization structure for the plan. Under the government leadership, it was national R&D that led to the resolution of a good number of technological problems, efficiently, by absorbing imported technologies and effectively adapting them to local circumstances.

The effects of indigenous bacteria on geochemical behavior of As in As-contaminated sediments (Hwachon mine and Myoungbong mine) after biostimulation with a variety of carbon sources were investigated under anaerobic condition. In Hwachon sediment, As was dramatically extracted from nonsterile sediment with time, reaching the highest concentration of $500{\mu}g/L$. The As leaching was likely caused by microbial dissolution of Fe oxides/oxyhydroxides with which As had been coprecipitated. However, in the case of Myoungbong sediment supplied with glucose, dissolved As decreased with time likely due to production of As sulfide(s) and subsequent precipitation, which resulted from bacterial reduction of $SO_4^{2-}$. The results implied that bacterial in-situ stabilization of As In subsurface has a potential to be practically applied.

Two 1-year-old Korean native steers in the same herd presented severe hemorrhagic diarrhea. Case 1 had severe dehydration and died after 3 days, whereas case 2 had anorexia, depression, and severe diarrhea with mucus and blood. Only case 2 was necropsied, and bovine viral diarrhea virus-2a (BVDV2a) was detected in the tissues of its alimentary tract. Gross lesions, including erosion, ulceration, and extensive hemorrhage, were observed in the digestive tract mucosa. Immunohistochemistry revealed marked positive staining for BVDV2a antigen in the large intestine. These findings are indicative of hemorrhagic disease caused by BVDV2a in a native Korean steer.

말라리아는 세계적으로 매년 1억 이상의 환자를 발생시키며 그 중 약 100만 명씩을 사망케 하고 있는 무서운 원충 질환으로 잘 알려져 있다. 우리 나라에는 과거에 삼일열 말라리아 (tefilnmuwia)의 유행이 있었으나 1970년대 말 이후부터는 토착적 환자 발생 보고가 없어 소멸된 것으로 알려져 왔다. 그러나 최근 저자 등은 해외 여행 경력이 없는 환자 1명에서 삼일열원충 (Plasmodium vivax) 감염을 확일하였기에 보고하고자 한다. 환자는 23세 남자인 국군 병사로서 1993년 7월 중순부터 18일 동안 격일로 매회 4-8시간씩 계속되는 발열과 오한을 주소로 내원하였다. 환자는 경남 창원시에 거주하였고 1992년 6월 군에 입대한 후에는 경기도 파주군의 한 야전군 부대에 근무해 왔으나 외국에 나간 일은 전혀 없다고 하였다. 과거력상 수혈을 받거나 정맥주사를 맞은 일도 없다고 하였다. 환자의 말초혈액 도말 표본에서는 삼일열원충의 ring form, trophozoite, schizont 및 gametocyte가 검출되었고, 약간의 적혈구 감소와 혈소판 감소가 관찰되었다 확진 후 hydroxychloroquine과 primaquine을 투여하여 치료하였고, 추적 혈액 도말검사에서는 말라리아 원충을 발견할 수 없었다. 이 증례가 우리 나라 토착적 말라리아의 재유행에 의한 것인지, 도입성 (introduced) 말라리아의 국내 정착에 의한 2차 감염 환자인지는 판단하기가 쉽지 않으나. 어쨌든 말라리아가 다시 유행할 가능성 에 대해서는 커다란 관심을 기울여 야 할 것으로 생각되었다.

피지는 남태평양의 해양 및 항공교통의 중앙에 위치함으로서 남태평양의 허브로 간주된다. 세계경제 내에서 가장 급속하게 성장하는 관광은 이미 피지 내에서도 잘 정착되고 있다. 본 연구는 해외지역연구로서 피지의 생태관광 특성에 대해 탐구한 것이다. 본 연구의 목적을 달성하기 위해서 피지에 관한 문헌조사 후 Suva의 Raintree 로지, Kula 생태공원, Sigatoka 사구국립공원 그리고 Nadi 부근 Nalesutale 피지 원주민마을에 현지답사를 수행하였다. 관광시설과 프로그램의 대부분은 환경적, 경제적 및 교육적 효과를 위해 개발되었다. 피지의 사례연구들은 한국에서 생태관광과 환경보전이 성공할 수 있는 좋은 모델을 보여주고 있으며, 환경친화적 관광산업을 위한 효과적인 지역정책수립에 일조를 기할 것이다.
