A gene related to high pristinamycin yield in Streptomyces pristinaespiralis was selected by amplified fragment length polymorphism (AFLP) and its functions were investigated by gene disruption. First, a 561 bp polymorphic sequence was acquired by AFLP from high-yield recombinants compared with the S. pristinaespiralis ancestor ATCC25486, indicating that this approach is an effective means of screening for valuable genes responsible for antibiotic yield. Then, a 2,127 bp open reading frame of a gene designated spy1 that overlaps with the above fragment was identified and its structure and biological functions were investigated. In silico analysis of spy1 encoding a deduced 708-amino-acid-long serine/threonine protein kinase showed that it only contains a catalytic domain in the N-terminal region, which is different from some known homologs. Gene inactivation of chromosomal spy1 indicated that it plays a pleiotropic regulatory function in pristinamycin production, with a positive correlation to pristinamycin I biosynthesis and a negative correlation to pristinamycin II biosynthesis.

Children team about their roles through literature, receive the information about the roles of family members and come to accept them. Especially, father's roles in biographies are so diverse, not consistent, compared to mother's roles, that it world be judged to be difficult for the children who had read to form the concept of the father's roles. As the father's roles in the fairy tales have important effect upon the formation of the children's role concept toward their fathers, the purpose of this study is to investigate the father' role appeared in Korean biographies. The method used for this study is the content analysis of the context related with fathering in Korean biographies. It is found that the most frequent father' role appeared in Korean biographies was a friend and companion such as to talk with child about the child's future. And the second frequent father's role in Korean biographies was a family ancestor, such as, to pray for a son's birth, to name the child, to arrange the child's marriage. The third role was that of a loaming helper. These results have been discussed in the light of former studies, and the limits of study method also have been discussed.

The annals of the Chosun dynasty (朝鮮王朝實錄). on CD-ROM was studied to understand e ceremony and dietary culture of the Chosun dynasty. The Chunshin (薦新) ceremony. the service of offering the first food product of the year to ancestors, was begun in the Song dynasty in China and initiated in the Koryo dynasty in Korea. Chunshin ceremony as the national auspicious ceremony was settled through the 311 the Chosun dynasty. The offerings were graded and the Saongwon (司饔院) was in charge of the transportation of them. A king attended the ceremony in person at Jongmyo (宗廟) once in a while. but the Bongsangsi officials usually took charge of ceremony. Even though the harvest of crops had failed due to the drought. the quantity of the offering was not curtailed. Seven kinds of the new products It ere offered in the Koryo dynasty, twenty-seven kinds of them during the reign of king Sejong, and thirty-one kinds of the them during the reign of King Sungjong according to the Gukjooreeui (國朝五禮儀) (1474). The offerings were served on the utensils called Du (두(豆)), Byun (遼), and Jak (爵). Most of the of the offerings were dedicated by public officials and civilians. The meat products in particular were caught by the king on hunting trips, and offered by the king in Person.

A method for the identification of structural characteristic parameters of a steel bar in the matrices form such as stiffness matrices and mass matrices from frequency response function(FRF) by genetic algorithm is proposed. As the method is based on the finite element method(FEM), the obtained matrices have perfect physical meanings if the FRFs got from the analysis and the FRFs from the experiments were well coincident each other. The identified characteristic matrices from the FRFs with maximun 40 % of random errors by the genetic algorithm are coincident with the characteristic matrices from exact FEM FRFs well each other. The fitted element diameters by using only 2 points experimental FRFs are similar to the actual diameters of the bar. The fitted FRFs are good accordance with the experimental FRFs on the graphs. FRFs of the rest 9 points not used for calculating could be fitted even well.

The genetic diversity plays a significant role in determining a species' survival and perseverance. Endangered species often lack genetic variation, which makes them vulnerable to numerous dangers of extinction including selection, genetic drifts and human interference. Knowing an endangered species' genetic background greatly enhances conservation efforts since it reveals why, what and how to conserve that species. Cotoneaster wilsonii is an endangered plant species endemic to Ulleung island, but not enough genetic research has been done on this taxon for its effective conservation plans. In this study, three populations of C. wilsonii in Ulleung island underwent allozyme analysis through starch gel electrophoresis. 10 loci were analyzed and F-statistics was calculated. Overall data indicated that C. wilsonii possessed low genetic diversity with intense inbreeding, heterozygote deficiency and low differentiation among populations. These results implied that C. wilsonii was recently introduced to the Ulleung island from ancestor species, and did not have much time to differentiate. Current status of C. wilsonii habitats is very fragile and vulnerable, with increasing tourism constantly threatening the species' survival. It is very likely that C. wilsonii will become extinct in near future unless organized conservation protects its populations and genetic diversity.

''The King's Daughters' is referring to the approximately 900 young French women who immigrated to New France between 1663 and 1673. This program was sponsored by Louis XIV. The program was planned to increase New France's population both by encouraging the female immigrants to settle there and by promoting marriages, family formations and the births of children. Marguerite Bourgeoys was the first person to use the expression called as 'filles du roi' in her writings. She was the French foundress of the Congregation of Notre Dame of Montreal in the colony of New France which is now part of Quebec. After agreeing to marry, the couple took a marriage contract directly in front of a notary and the wedding ceremony had generally been held within possible rapid time. The processes of the choice of husband and the marriage would officially be held in the church. By the year 1672, the population of New France had risen to 6,700 from 3,200 in 1663. Although the Filles du Roi represent only 8% of the total immigrants to Canada under the French regime, they account for nearly half of the women who immigrated to Canada in the colony's 150-year history. 'King's Daughters' must be correctly assessed as 'Mother of Quebec' and 'Propagator of the French language' in the history.

Coreanomecon is a monotypic and endemic genus in Korea, distributed mainly in the southern regions. Coreanomecon is morphologically similar to Hylomecon by producing red latex, easily distinguished from Chelidonium, which produces yellow latex. Coreanomecon were merged into Hylomecon or Chelidonium depending on the authors. To understand the phylogenetic relationship of Coreanomecon, DNA sequences of chloroplast rbcL and matK and nuclear Internal Transcribed Spacer (ITS) regions were determined from the species of Papaveroideae (Papaveraceae) in Korea and analyzed with the Maximum Parsimony and Bayesian methods. Phylogenetic analyses of Papaveroideae suggest that Coreanomecon is sister to the clade of Chelidonium and Stylophorum in the ITS data and that it is sister to Hylomecon in the chloroplast (cpDNA) data. A constraining analysis using the Shimodaira-Hasegawa test (S-H test) suggested that the ITS data do not reject the sister relationship of Coreanomecon and Hylomecon. The S-H test also suggested that the cpDNA data is compatible with the placement of Coreanomecon as a sister to the clade of Chelidonium and Stylophorum. Although the conflicting phylogenetic results may stem from insufficient phylogenetic signals, they may also be associated with hybridization between Hylomecon and an ancestor of Stylophorum and Chelidonium. The results of this study suggest that Coreanomecon is a distinct lineage as an endemic genus, supporting the morphological data.

The Lord of Mayan society was a person who was thought to be able to understand phenomena in the universe. And also the Lord could realize these activities of heaven on Earth through ritual. But the manifested ritual function of lordship was very different depends on Classic and Postclassic period. The Classic Mayan rituals were closely related to personal dignity, specially royal blood tradition meanwhile the Postclassic Mayans focused on public function of ritual. The ritual sacrifices of blood letting from their own body, manifested in Yaxchilan Lintel 24, 25 and 17, were focused on royal family's activity, showing the dignity of royal blood. The same ritual about the birth of family successor was observed at the Structure 5C4 from Postclassic ruin of Chichen Itza. However, this scene in focus, was two representative men and the answer of ancestor, not a special person. Also at the Lintel 1 of Temple of Four Lintels it was observed names of four Lords of Chichen Itza, their relationship, their action of firing to dedicate temple instead of writing long history of great royal family. All above shows that during Postclassic period the lords preferred a public function of their lordship than to dignify some royal persons through ritual.
