  • This study sought to observe systematic relationships through taximetrical analyses by morphological characters among the 10 species, on three species in the virilis section (D. virilis, D. tsigana and D. lacertosa) and seven species in the quinaria section (D. angularis, D. brachvnephros, D. curvispina, D. kuntzei, D. nigromaculata, D. takadai and D. unispina) of the subgenus Drosophila. In the cluster and the cladistic analysis among the members of subgenus Drosophila, 10 species was divided into the 1st group of D. virilis, D. tsigana, and D. lacertosa and the 2nd group of D. angularis, D. brachynephros, D. curvispina, D. kuntzei, D. nigromaculata, D. takadai, and D. unispina. In cluster analysis, the 2nd group had three sister groups; one sister group that clustered D. angularis and D. brachynephros then D. unispina was clustered to them, another sister group clustered D, curvispina and D. takadai then D. kuntzei was clustered to them and the other sister group of D. nigromaculata. In the 10 species, D. virilis and D. lacertosa were the first to be divided and then D. tsigana. Although 1st group which D. virilis was belonged can be determined as more primitive than the 2nd group, it seemed that this group was not the direct ancestor of the 2nd group, rather there should be another ancestor. Among the quinaria species group, D. nigromaculata was the first to be divided and D. kuntzei was the most recent species to be divided.

  • We present an efficient data structure to obtain the range minima in an away in constant time. Recently, suffix ways are extensively used to search DNA sequences fast in bioinformatics. In constructing suffix arrays, solving the range minima problem is necessary When we construct suffix arrays, we should solve the range minima problem not only in a time-efficient way but also in a space-efficient way. The reason is that DNA sequences consist of millions or billions of bases. Until now, the most efficient data structure to find the range minima in an way in constant time is based on the method that converts the range minima problem in an array into the LCA (Lowest Common Ancestor) problem in a Cartesian tree and then converts the LCA problem into the range minima problem in a specific array. This data structure occupies O( n) space and is constructed in O(n) time. However since this data structure includes intermediate data structures required to convert the range minima problem in an array into other problems, it requires large space (=13n) and much time. Our data structure is based on the method that directly solves the range minima problem. Thus, our data structure requires small space (=5n) and less time in practice. As a matter of course, our data structure requires O(n) time and space theoretically.

  • The descendants of Jang, Chang-woo(張昌雨) reconstructed the Mangwijung (晩歸亭), which is currently located at Seha-dong, Seo-gu, Gangju Metropolitan City, in the context of succeeding the work of their ancestor. This study investigated the management viewpoint of Mangwijung that has been altered in going through the reconstruction and repairs processes, and examined the chronological history for a landscape of the Mangwijung Garden. First, in the Mangwijung Garden, three gazebos such as Mangwijung, Seubhyanggag(襲香閣) and Mukamjeongsa(墨庵精舍) stand in a row with three bridges between each of them in the middle of a wide pond. This is a group of gazebos that is a quite unique structure. Second, Hyowoodang(孝友堂) Jang, Chang-woo (張昌雨) built Mangwijung as a role of thatched cottage in order to teach younger students and enjoy the arts in his later life. The Mangwijung was reconstructed by the descendants of Jang, Chang-woo at the collapsed place later on in order to commemorate the achievements of their ancestor. By the way, it was revealed that the management of Mangwijung has been altered during the process of reconstruction. Third, when comparing the current appearance with those depicted in the 8 scenic views(八景) by Jang, Chang-woo and the literary works of his descendants, it was confirmed that the landscape and shape of the pond were damaged due to a road expansion caused by a construction of Seubhyanggag and Mukamjeongsa as well as an advancement of the city. Fourth, it is speculated that the pond of Mangwijung Garden is probably a spring not a reservoir to store the water stream that flows in.

  • The purpose of this research paper is to study the characteristics of Huang Yunseok's sijo and it's implications for his poetic intentions. Huang Yunseok's sijo is didactic in its presentation of facts and ethical lessons. The two main facts it presents are royal favors and his clan's pride. Royal favors concern. for example, encouragement of the king, the king's birthday and deathday, and securing a government position by the king's order. His clan's pride concerns, for example, the geographically wonderful place of Huang Yunseok's ancestor's tomb, his ancestor's great conduct, his clan's beautiful tradition, his birth place, and his birth dream. The main content of the ethical lessons concerns cultivation of the human mind and practicing Confucian ethics. Examples of the former describe the purpose of Confucian study, the ethical doctrine that human being's inborn nature is good, the character of the human mind, and the method of cultivating the human mind. Examples of the latter describe the moral rules to govern the Five Human Relations, separation between husband and wife, and discrimination between males and females. The poetic intention of Huang Yunseok's sip consists of political and economic self-promotion and theoretical devotion to Confucian ideology. Proud of his educated, high Confucian clan, he tries to get self-promotion politically and economically by vowing loyalty to the king. He implies devotion to the Confucian ideology through his description of the practice of the Confucian moral rules, the clinging to traditional Neo-Confucianism, and his insistence on the Neo-Confucian theory that all human beings and animals are the same in their original nature. In conclusion, the didactic character of Huang Yunseok's sip stems from his intention to promote himself politically and economically and his theoretical devotion to Confucian ideology. The way of indicative expression originates from the didactic character of Huang Yunseok's sijo.

  • The purpose of the present study is to explore the significance of the Commentaries on Pavilions (樓亭記) from the Sancheong-gun area. To achieve this purpose, the study analyzes the works handed down in Sancheong-eup, Chahwang-myeon, Obu-myeon, and Geumseo-myeon, focusing on the two characteristic themes: the discipline and enlightenment of heart and mind (in Chapter 2) and the succession of integrity and the tradition of ancestor worship (in Chapter 3). The first characteristic theme "the discipline and enlightenment of heart and mind" is explicated in Chapter 2 by reviewing the Commentary on Hwanajeong Pavilion (Hwanajeonggi) written for the namesake building located in Sancheong-ri, Sancheong-eup, and the Commentary on Gyeongjeonjae Pavilion (Gyeongjeonjaegi) in Maechon-ri, Geumseo-myeon. The second theme "the succession of integrity and the tradition of ancestor worship" is examined in Chapter 3 based on the Commentary on Sulgojeongsa Pavilion (Sulgojeongsagi) from Jangwi-ri, Chahwang-myeon, and the Commentary on Maeranjeong Pavilion (Maeranjeonggi) from Yangchon-ri, Obu-myeon.

  • In this paper, we focus on efficient construction of tightest matched subtree (TMSubtree) results, for keyword queries on extensible markup language (XML) data, based on smallest lowest common ancestor (SLCA) semantics. Here, "matched" means that all nodes in a returned subtree satisfy the constraint that the set of distinct keywords of the subtree rooted at each node is not subsumed by that of any of its sibling nodes, while "tightest" means that no two subtrees rooted at two sibling nodes can contain the same set of keywords. Assume that d is the depth of a given TMSubtree, m is the number of keywords of a given query Q. We proved that if d ${\leq}$ m, a matched subtree result has at most 2m! nodes; otherwise, the size of a matched subtree result is bounded by (d - m + 2)m!. Based on this theoretical result, we propose a pipelined algorithm to construct TMSubtree results without rescanning all node labels. Experiments verify the benefits of our algorithm in aiding keyword search over XML data.

  • This study surveyed features of weddings in the main family by selecting 10 families in which the grandnephew and grandnephew's wife dwell in the head house, have a shrine, and hold a memorial service for Bulcheonwi (不遷位). A case survey through in-depth interview was carried out from April 9, to October 8, 2011. It surveyed the contents and the wedding artifacts in Uihon (議婚), Napchae (納采), Nappye (納幣), Daerye (大禮), Hyeongugorye (見舅姑禮), which are the procedures of traditional wedding that have been kept in the wedding ceremony of the main family. As a result, in deciding on marriage, the marriage was formed on the basis of similar Gagyeok (家格) and on ancestor's common scholastic mantle or origin. As for wedding furnishings, wedding presents, and wedding gifts, 9 out of 10 families were indicated to give and take weakly. Also, 6 out of 10 families held a traditional wedding ceremony in the yard of the bride's house. Hyeongugorye (見舅姑禮) was indicated to be held by all of the 10 families. A continuous effort in academic circles and industries is demanded for preserving the living culture of the main family, which proceeds with following the traditional elements even amid a rapidly-changing historical flow as today.

  • The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yo tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery pattern has a high artistic value in that its shapes are diverse and splendid and each one has its own peculiar elegance. As for the research method, I examined the Yo tribe's history, culture, traditional costumes and design patterns through related books, research papers, internet sites, and etc. The results of the paper are as follows. The Yo tribe's costumes consist of a jacket, trousers or a skirt, an apron and a belt. Although the color of the costumes is all black, there are splendid embroidery decorations with the colors of red, orange, yellow, green and white on the chest or shoulder part of a jacket, the adjusting lines, cuffs, or a part of a trousers and aprons. The types of the patterns represented in the Yo tribe's traditional costumes are related to nature, ancestor worship, ethnic legends, history, religion, and agricultural lives. The method by which the Yo tribe expressed on their costumes is a "peach-blossom" technique, which uses cross-shaped embroidery with wrap and woof threads. Because it is not apt to express delicate and detailed patterns, the Yo tribe's patterns tend to show abstract and geometrical forms.
