The Red Queen hypothesis for the advantage of sex predicts that pathogens will evolve by increasing fitness with frequent encounters with specific host genotypes. In this study, BMV population size, measured as an indicator of fitness, was investigated during repeated passages through the same, or different host genotypes of the crop host, Hordeum vulgare (barley). Overall, mean BMV concentration within individual hosts was significantly higher in genetically homogeneous compared to heterogeneous host passage lines. In addition, BMV populations, passaged through a specific host variety, showed higher growth in that host variety compared to BMV passaged through varying varieties. These results supports the Red Queen hypothesis. However, the decrease in viral populations during passages contradicts the Red Queen. Nevertheless, the results found here show that even under simplified conditions, pathogens do not evolve in simple, predictable ways. Constraints on pathogen evolution may lead to counterintuitive results.

From the period of King Tae-Jong up to the third year of King In-Jo, the bestowal system for queen's court dresses from the Myeong Dynasty was one which was much lower than that of China. This system was applied to the queens' court dresses in the early Yi Dynasty. The pheasant's pattern on Jeockwan and Hapee probably indicates that Daesam was possibly regarded as Jeockyoe. In fact, according to Kaeredogam, Jeockyoe was for the first time made in the third year of King Kwanghae, which is the oldest record on Jeockyoe and Daesam. At the age of King Seon-Jo, a new type of queen's clothing was taken as an inevitable result of Japanese Invasion. Jeockyoe system was gradually made ceremonious until the period of King Yeong-Jo through Kakhonjeongye and Kukjosokoryeycobo; it became that of Queen Myeong-Jo's in the end. The traditional Jeockyoe system might have been interblended with Daesam. Yeodae was queen's usual dress and its pattern was the same as that of every women's dresses at Court.

This paper proposes a fast optimization method by combining queen-bee evolution and derivative evaluation in genetic algorithms. These two operations make it possible for genetic algorithms to focus on highly fitted individuals and rapidly evolved individuals, respectively. Even though the two operations can also increase the probability that genetic algorithms fall into premature convergence phenomenon, that can be controlled by strong mutation rates. That is, the two operations and the strong mutation strengthen exploitation and exploration of the genetic algorithms, respectively. As a result, the genetic algorithm employing queen-bee evolution and derivative evaluation finds optimum solutions more quickly than those employing one of them. This was proved by experiments with one pattern matching problem and two function optimization problems.

강화학습(Reinforcement-Learning)의 목적은 환경으로부터 주어지는 보상(reward)을 최대화하는 것이며, 강화학습 에이전트는 외부에 존재하는 환경과 시행착오를 통하여 상호작용하면서 학습한다 대표적인 강화학습 알고리즘인 Q-Learning은 시간 변화에 따른 적합도의 차이를 학습에 이용하는 TD-Learning의 한 종류로서 상태공간의 모든 상태-행동 쌍에 대한 평가 값을 반복 경험하여 최적의 전략을 얻는 방법이다. 본 논문에서는 강화학습을 적용하기 위한 예를 n-Queen 문제로 정하고, 문제풀이 알고리즘으로 Q-Learning을 사용하였다. n-Queen 문제를 해결하는 기존의 방법들과 제안한 방법을 비교 실험한 격과, 강화학습을 이용한 방법이 목표에 도달하기 위한 상태전이의 수를 줄여줌으로써 최적 해에 수련하는 속도가 더욱 빠름을 알 수 있었다.

Alexander McQueen is a typical designer of unconventional and experimental design who showed maximalism through outstanding tailoring. The purpose of this research is to study formative characteristics of maximalism that are expressed in modern fashion based on the works of Alexander McQueen, and to suggest boundless possibilities of development through his sense of design and the expressive ability of his works. Theoretical considerations will be made through literature research and precedent studies, and the collection data for case analysis will be used to select ready-to-wear women's collections from 2001 S/S to 2010 F/W by referring to internet sites. The study results are as follows. First, the most representative characteristic of formative characteristics of maximalism expressed in Alexander McQueen's works is expandability. Second, decorations used as a part of detail on clothes is used as decoration itself, and handcraft expression is shown through excessive use of decorations. The expandability of decoration that emphasizes splendid magnificence is expressed through flawless technique. Third, the fusion of each different image and the combination of ethnic image and modern image was most prevalent. Fourth, fantasy expresses a fictive image that could not be seen in reality by expressing an unrealistic and maximized image through the imagination of designer. Fifth, experimental element is expressed as an image that actively reflects the challenging spirit, which suggests a new direction of beauty through shocking and extraordinary images of the inner world of the designer and the root of new ideas about inhumane modern society.

The pearl is a highly valuable gem that has historically represented wealth and power. Pearl necklaces have developed intro various types and represent an essential status item for modern women. This study first examines the symbolic and various meanings of pearls. Second, this study examines wearing types and pearl necklace patterns based on historical figures and modern fashion icons famous for personal displays of pearls. This study examines and analyzes various specialty publications about jewels, history of costumes, fashion magazines, academic research data, and internet search results. The conclusion of this study is as follows. Pearls have various symbolic meanings that are unlike other gems. Pearls represent purity, innocence, marital fidelity, an intimate relationship with the moon, frozen tears of God, solitude, triumph over adversity, wisdom, and sensual attraction. The societies and people traditionally famous for pearls were the Roman Empire, Queen Cleopatra of Egypt, Queen Theodora of the Byzantine Empire, Queen Elizabeth I, Queen Marie Antoinette, Empress of Eugenie Napoleon III, and Queen Alexandra. They showed a special affection for pearl necklaces and various wearing patterns unique to the time. Their pearl necklaces became a historic and symbolic legacy. Reestablished through the costume jewelry of cultivated pearls designed by Coco Chanel in the $20^{th}$ century, the pearl necklace has showed a variety of fashion trends in addition to a traditional symbolism of wealth and power. Josephine Baker, Louise Brooks, Marilyn Monroe, Elizabeth Taylor, Jacqueline Kennedy, Queen Elizabeth II, Princess Diana, Michelle Obama and Sarah Jessica Parker have worn notable pearl necklaces and established an individual style that utilizes the adornment of fashionable and stylish pearl necklaces. They have worn pearl necklaces while applying various fashion trend motifs to symbolic pearl features of that have changed the perception of the pearl and themselves.

In this essay, I compare the ways in which the mid-thirteenth century English romance, Floris and Blancheflour, represents relationships of the Spanish pagan queen to her adoptive Christian daughter who becomes her daughter-in-law, with the ways in which Chaucer's Man of Law's Tale and other so-called Constance romances delineate relationships between mothers-in-law and daughters-in-law. What draws me into these romances is the fact that they both convey the intergenerational relationships of women. However, the texts become distinct from each other in the way in which each depicts women characters and their relationships with one another. In this paper, I argue that the level of intimacy that the mother-in-law figure has with the daughter-in-law figure plays a defining role in making the former perform her agency for or against the latter. In the Man of Law's Tale and other Constance romances, the daughter-in-law figure is in every sense an alien or 'outsider' to the mother-in-law figure. To the contrary, Blancheflour in Floris is a sort of 'insider' to the queen because they lived in the same household for fourteen years-ever since the girl's birth. The queen, therefore, should have a high degree of intimacy with Blancheflour. I argue that the pagan queen's intimacy to the daughter of a Christian-European captive has enabled the queen to protect the girl as her adoptive daughter first and as a daughter-in-law second, namely contributing to her unreserved endorsement of the inter-racial-religious-class union between her only son, Floris, and Blancheflour. This is one major factor that distinguishes the relationship of the queen and Blancheflour in Floris from the dysfunctional relationships of mothers-in-law and daughters-in-law in the late medieval Constance romances, where women of different generations are strangers to each other, and no way is imagined for women of different races and religions to get along with each other.
