  • World wheat production is now under threat due to the wheat blast outbreak in Bangladesh in early March 2016. This is a new disease in this area, indicating the higher possibility of this pathogen spreading throughout the Asia, the world's largest wheat producing area. Occurrence of this disease caused ~3.5% reduction of the total wheat fields in Bangladesh. Its economic effect on the Bangladesh wheat market was little because wheat contributes to 3% of total cereal consumption, among which ~70% have been imported from other countries. However, as a long-term perspective, much greater losses will occur once this disease spreads to other major wheat producing areas of Bangladesh, India, and Pakistan due to the existing favorable condition for the blast pathogen. The wheat blast pathogen belongs to the Magnaporthe oryzae species complex causing blast disease on multiple hosts in the Poaceae family. Phylogenetic analysis revealed that the Bangladesh outbreak strains and the Brazil outbreak strains were the same phylogenetic lineage, suggesting that they might be migrated from Brazil to Bangladesh during the seed import. To protect wheat production of Bangladesh and its neighbors, several measures including rigorous testing of seed health, use of chemicals, crop rotation, reinforcement of quarantine procedures, and increased field monitoring should be implemented. Development of blast resistant wheat varieties should be a long-term solution and combination of different methods with partial resistant lines may suppress this disease for some time.

  • Vibrio vulnificus, a normal bacterial inhabitant of estuaries, is of concern because it can be a potent human pathogen, a causing septicemia, wound infections and gastrointestinal disease in susceptible host. In this survey, total 431 samples were obtained from different sites of the Chonman coastal area during the periods from Mar. 1997 to Feb. 1998. Vibrio vulnificus was isolated from the middle of May to the begining of November of 1997 in Chonman coastal area, as the seawater temperature was at 20$^{\circ}C$ and 15$^{\circ}C$, respectively and was rapidly increased to above 40% from July to September. The isolation rates of V. vulnificus from sediment, seawater, raw seafoods and aquarium water were 52.1%, 49.1%, 32.5%, and 27.3%, respectively and isolation rate was highest in oyster among various collected samples. V.vulnificus was also isolated from 73.1%(38/52) of sampling sites of Chonman coastal area.

  • Fe (III) impurities in clay could be microbially removed by inhabitant dissimilatory Fe (III) reducing microorganisms. Insoluble Fe (III) in clay particles was leached out as soluble reductive form, Fe (II). The microorganisms removed from 10 to 45% of the initial Fe (III) when each sugar was supplemented to be in ranges of 1 - 5 % (w/w; sugar/clay). The microorganisms reduced 2.1 - 12.8 mol of Fe (III) per 100 mol of carbon in sugars metabolized when sugars such as glucose, maltose, and sucrose were used as sole carbon source. Bacillus sp. IRB-W and Pseudomonas sp. IRB-Y were isolated from the enrichment culture of the clay. The isolates were considered to participate in metabolizing organic compounds to fermentative intermediates with relatively little Fe (III) reduction at initial Fe (III) reduction process. By the microbial treatment, the whiteness of the clay was increased form 63.20 to 79.64, whereas the redness was obviously decreased form 13.47 to 3.55. This treatment did not cause any unfavorable modifications in mineralogical compositions of the clay.

  • Swine dysentery caused by Brachyspira hyodysenteriae, an anaerobic, beta-hemolytic spirochete, is a severe mucohemorrhahic diarrheal disease that primarily affects pigs during the growing and finishing period. The current standard laboratory procedure to culture and identify B hyodysenteriae takes 3 to 7 days. This report present a rapid PCR for detection B hyodysenteriae in a single reaction using DNA from swine intestinal samples. The PCR produced a specific 421bp PCR product with template DNA purified from B hyodysenteriae, and the accuracy for detection of B hyodysenteriae by PCR results compared with those of conventional method was 100% in intestinal specimens. Nonspecific bands were not detected with B innocens, a nonpathogenic common inhabitant spirochete, including other enteric bacterial organisms. This procedure could detect as little as 50 pg of template DNA for B hyodysenteriae.

  • This research is related to house entrance recognition of residents, who have long kept the entrance without a closing door in Eoeun village, Geumho, Keongbook. The purpose of the research was to interpret the recognition of a house entrance in Eoeun village with the theories of cultural ecology. Final results suggest the belief for all the inhabitant\`s welfare through anthropological adaptation to habitat. The fish in the Geumho River had sought the shelter from the heavy rain in summer. The Eoeun forest at the entrance of the village provided good shelter for the fish. The Eoeun residents thought that the safe shelter fur the river fish is also semantic for the people. They believed that if the fish could not find shelter, i.e., the Eoeun forest and left, the village could be not safe for their life. Therefore, even the entrance of house should be structurely opened for the fish shelter in a symbolic sense. The entrance without a closing door has implied that their life should depend upon their natural environments because they have believed that till now there have been no considerable accidents in the village.

  • In recent years, the objective information for the environmental effect of architecture will be furnished to the designer and inhabitant in order to minimize an excessive energy consumption and environmental loads by buildings. In addition, an environmental friendly architectural certification program for a residence, office, and school facilities have been operated to spread and supply environmental friendly architecture. Most of the environmental friendly architectural certification programs proposed in the country are focused on the aspect of the physical environments of architecture in its certification ranges. In the case of a foreign country, however, the certification ranges of an environmental friendly architectural certification program for the school facilities among the programs will be extended not only to the standards for architectural design, environmental aspect, and maintaining and management basis by considering the characteristics of educational effects for students but also to the curriculum, policy of environment, and roles of local community facilities by reflecting a social aspect. Therefore, this study proposes a design and evaluation method by considering an ecological element that will satisfy the requirement for educational well-being that includes not only the requirement for school facilities according to the development of a new curriculum like a space for teaching and learning but also the improvement of the quality of educational environments and the objective of an ecological school.
