In this study, I have tested the effects of the agents and dyeing conditions on the Brazil-wood dyestuff as one plant dyestuffs. According to the tests, I have fount that color differenciation depending opon the agents and procedual condtitions. As the agents, Alm induced redness and light yellowness by Aluminum Acetate, dark greenness or blueness by Ferrous chloride, dark redness by Stannous Chloride, dark grenness or blueness by Copperous Chloride, light yellowness or greenness by Calcium Dihydroxide. On the other hand, color-fastness differed from various mordant agents. The color-fastnes was solid using multiple agents than sole agent.

Distributed Artificial Intelligence (DAI) aims to study and develop techniques that allow interaction among intelligent entities. In the last two decades, some types of DAI architecture have been proposed for various fields. However, it can be noticed that the inconsistency phenomenon has not been dealt with properly. This is probably due to the fact that this phenomenon cannot be handled (at least directly) with classical logic. Hence, to deal with such inconsistencies directly, one should employ a logic other than the classical one. The DAI Architecture described in this work is based on a nonclassical logic called Annotated Paraconsistent Logic.

Precipitation measurement with ground-based radar needs an information of the raindrop size distribution (RSD) characteristics. A 10-month dataset was collected in tropical Atlantic coastal zone of northeastern Brazil where the weather radar was installed. The number of drop was mainly recorded in 300 - 500 drop $mm^{-3}$, of which the maximum was registered around 1.1 mm drop diameter.

To address the diversity of cyclodextrin-producing P. graminis strains isolated from wheat roots and rhizospheres of maize and sorghum sown in Australia, Brazil, and France, restriction fragment length polymorphism analysis of part of genes encoding RNA polymerase (rpoB-RFLP) and DNA gyrase subunit B (gyrB-RFLP) was used to produce genetic fingerprints. A phylogenetic tree based on rpoB gene sequences was also constructed. The isolates originated from Brazil could be separated from those from Australia and France, when data from the rpoB-based phylogenetic tree or gyrB-RFLP were considered. These analyses also allowed the separation of all P. graminis strains studied here into four clusters; one group formed by the strains GJK201 and $RSA19^T$, second group formed by the strains MC22.02 and MC04.21, third group formed by the strains TOD61, TOD 221, TOD302, and TOD111, and forth group formed by all strains isolated from plants sown in Cerrado soil, Brazil. As this last group was formed by strains isolated from sorghum and maize sown in the same soil (Cerrado) in Brazil, our results suggest that the diversity of these P. graminis strains is more affected by the soil type than the plant from where they have been isolated.

The present study was carried out to compare the composition of major essential oil components in the flue-cured tobacco produced by Korea, America, China, Brazil and Zimbabwe. Above 100 essential oil components were separated by GC and major 18 components of them, known to be important contributors to flue-cured tobacco flavor and smoke taste, were identified by GC/MS. Neophytadiene was major in quantities in the oils mostly and its composition in flue-cured tobacco produced by Korea, America, Zimbabwe, Brazil, and Unnam and Yenji region of China was 26.82\%,\;25.17\%,\;26.50\%,\;16.92\%,\;and\;18.75\%\;and\;14.87\%$, respectively. Megastigmatrienone, one of the major tobacco carotenoid degradation products was contained above $10\%$ in the oils of flue-cured tobacco produced by Korea and America, but, it was comprised about $5.66\%$ to 8.00 in Brazil, Zimbabwe, and Unnam and Yenji region of China. Damascenone is important to the aroma of tobacco as a crotenoid degradation products. Its amount in the oils was $3.31\%\;in\;Brazil,\;3.13\%\;in\;America,\;2.57\%\;in\;Zimbabwe,\;2.54%$ in Yenji of China, $2.00\%$ in Korea and $1.85\%$ in Unnam of China. These results can furnish the basic information capable of evaluating the quality value of flue-cured tobacco produced by various nations.

Strains of Toxoplasma gondii in Brazil are highly genetically diverse compared to strains from North America and Europe. Dogs are epidemiologically important because they act as sentinels for T. gondii infections in humans and are good indicators of environmental contamination. The aim of this study was to isolate and genetically characterize T. gondii strains from tissues of naturally infected Brazilian dogs. For this study, 21 blood samples were collected from dogs at the Zoonosis Control Centers of $Ilh{\acute{e}}us$ and Itabuna cities, Bahia, Brazil. The sera were examined for T. gondii antibodies using the indirect hemagglutination test. Brains and hearts of seropositive dogs were bioassayed in mice to isolate and characterize T. gondii parasites by PCR-RFLP using 10 genetic markers (SAG1, newSAG2, SAG3, BTUB, c22-8, c29-2, GRA6, PK1, APICO, and L358). However, T. gondii was isolated from only 4 (57.1%) dogs, designated TgDgBr6, 13, 17, and 21. All strains were virulent, causing clinical changes (rough hair coat, lethargy, and abdominal distention) and the death of all mice within 8-20 days after inoculation. Genetic analysis of these 4 T. gondii isolates revealed 4 distinct genotypes with different clonal lineage combinations (types I, II, and III) and 2 atypical alleles. Using PCR-RFLP with several markers, this study contributes to evaluations of the genetic diversity of strains circulating in Brazil.

Recently, 'happiness' has become a major issue of national level, exceeding the matter of personal issue. Especially, Korea has actually increased its GDP by focusing on the economic growth for decades, and now it has achieved the economic/technical development as an IT power. However, Korean people's satisfaction with life called 'happiness index' is moving back every year. Even though there have been continuous efforts to enhance the national happiness by mentioning it as an essential issue in the national level, there are not many researches related to it. This study drew measures to enhance happiness by extracting happiness factors and unhappiness factors of Korea through social network service. Especially, it aims to analyze, compare, and apply happiness factors and unhappiness factors of three countries such as the US, UK, and Brazil with higher happiness indexes than Korea. For this, through the topic modeling of text mining technique, postings including keywords about happiness and unhappiness were collected/analyzed from Twitter of Korea, the US, UK, and Brazil. The significance of this study is to discuss measures to increase happiness and to decrease unhappiness by mining/analyzing the actual public opinions about happiness and unhappiness in four countries like Korea, the US, UK, and Brazil by using the topic modeling. Through this, the quality of life of Korean people could be improved by suggesting measures to enhance happiness and to decrease unhappiness in the level of individual, family, society, and government.

Hanyak, Korean herbal medicine is defined as the herbs understood and explained by traditional Korean medical theories. Considering this definition, there are broad prospective of every species being consilienced and utilized as Korean herbal medicine. Most varied plant species are in tropical regions, and its of these regions posses its own particular traditional medicine. Brazil posses the most varied and abundant plant species and also characteristic traditional medicine, formed by the combination of native indians and immigrants from Africa and Europe. Brazilian traditional medicine are practices by 'garrafeiros', 'raizeiros', or 'curandeiros' and in Caatinga uses herbs in ritual ceremonies. But threatened by modernization, these knowledge may be vanished in a prompt time. Therefore we carried this research in the propose of understanding as well as preserving their traditional medical knowledge. We revised publications about the medical plants and summarized 314 species of 94 families according to repetitive references. The most cited families were COMPOSITAE, LABIATAE, LEGUMINOSAE, RUBIACEAE, SOLANACEAE, UMBELLIFERAE, VERBENACEAE. Also cited major medical efficacies which further medical uses in combinations or modification of current traditional Korean medicine should be studied. This study provides overall prospect of the plants resources of Brazil and their uses. It may serve in the consilience and understanding of varied traditional medicine by traditional Korean Medicine.
