  • In a large DNA database, indexing techniques are widely used for rapid approximate sequence searching. However, most indexing techniques require a space larger than original databases, and also suffer from difficulties in seamless integration with DBMS. In this paper, we suggest a space-efficient and disk-based indexing and query processing algorithm for approximate DNA sequence searching, specially exact match queries, wildcard match queries, and k-mismatch queries. Our indexing method places a sliding window at every possible location of a DNA sequence and extracts its signature by considering the occurrence frequency of each nucleotide. It then stores a set of signatures using a multi-dimensional index, such as R*-tree. Especially, by assigning a weight to each position of a window, it prevents signatures from being concentrated around a few spots in index space. Our query processing algorithm converts a query sequence into a multi-dimensional rectangle and searches the index for the signatures overlapped with the rectangle. The experiments with real biological data sets revealed that the proposed method is at least three times, twice, and several orders of magnitude faster than the suffix-tree-based method in exact match, wildcard match, and k- mismatch, respectively.

  • One of important goals for early childhood music learning program is to build a positive attitude toward music. Positive attitude toward music is a basic condition on effective music education for all ages of children including early childhood. Although scholars realize such importance of positive music attitude, much research for creating educational environment to foster a positive music attitude has not been performed. Edwin E. Gordon who found a music learning theory for early childhood emphasized the importance of enriched musical environment. Very young children should be provided best quality of music in an interactive way. Audie's important method of education is to provide young children with a variety of musical activities containing the materials in the ordinary life. Through this method, children accept music as close as friends who are always beside themselves, which naturally builds a solid foundation for audiation for children.

  • The global success of PSY's Gangnam Style was mediated through combination of YouTube and SNS. PSY's success led into some communication scholars' consideration of new international circulation of Korean pop culture (Korean Trend 2.0). In terms of global circulation of pop culture, it is noticeable how users appropriate YouTube channel beyond mere watching music videos and mere international circulation of Korean pop culture. The mode of fan's activity and appropriation contributes to the expansion of the width and amplification of the volume of Korean popular culture as well. The circulation of pop culture was considered in the level of exchange of tangible commodities such as CD, DVD, and so on until the adoption of digital media and Internet. YouTube has brought new mode in which the international circulation of pop culture is mediated without exchange of tangible commodities but was amplified with the diffusion of network. This study grasps how the mode of users' appropriation contributes to international circulation of pop culture through case studies of some K-pop music videos and international K-pop fans' tribute activities. In terms of theoretical perspective, fandom studies will be examined. In terms of research method, the researcher adopts netnography, a participatory observation on network, to find the feature of fandom and its contribution to the international circulation of pop cultures.

  • The Uncanny Valley is a hypothesis introduced by a roboticist, Masahiro Mori. The theory holds that as robots and other facsimiles of humans look and act more human-like, the emotional response from a human spectator to them will become increasingly empathic, until they approach realistic similarity to humans but not quite exactly like them, when those images stop being likable and instead become repulsive and "uncanny." Although the scientific validity of this hypothesis is still debatable, it is true that many spectators has tendency to reject hyper-realistic animation. For that reason, the great success of the recent movie Avatar is remarkable. Computer animations that try to represent humans in hyper-realistic way fall into a paradox: successful result images would look too mundane and unsuccessful ones look "wrong". On top of that, audience would expect from hyper-realistic animation to see same level of acting of live-action films, which is usually not the case. The subtle differences between digital characters and real actors irritate spectators and hinder them in absorbtion. The biggest difference between Avatar and other hyper-realistic animation is the referent of their representation. While Avatar pursues a similar hyper-realistic visual style, the referents of the representation shown in this movie are totally alien to us thus impossible to compare with the real counterparts. Unlike characters in other hyper-realistic animations who had to fight an uphill battle with great actors in real life, those in Avatar have criteria of their own. That is why this movie can be free from the dreadful valley and let the audience absorb into the spectacle.

  • Chon-Mun-Ryu-Cho (天文類抄), written (edited) by Lee Sun-Ji (李純之) during the period of King Se-Jong, is a representative astronomy book of Cho-Sun (朝鮮: A.D. 1392-1910) Dynasty. We find and study in the first page of the book; the description of 28 oriental constellations as a Sasin (four mythical oriental animals)-animal sky map which is not widely known yet. The map consists of four groups of constellations, each of which represents the Sasin: Chang-Ryong (蒼龍: dragon), Baek-Ho (白虎: tige.s with Ki-Rin [離隣: Oriental giraffe]), Ju-Jak (朱崔: Chinese phoenix), Hyun-Mu (玄武: a tortoise interwined with a snake). Each group (animals) spans 2 ~ 7 of 28 oriental constellations (宿). As we know from the illustration (論說) of the Chon-Sang-Yol-Cha-Bun-Ya-Ji-Do (天象列次分野之圖), a representative sky map of Cho-Sun Dynasty, astronomy in Cho-Sun Dynasty is closely related to that in Go- Gu-Rye. (高句麗: B.C. 37 -A.D. 668) Dynasty. Since these Sasin-animals appear in most mural paintings of Go-Gu-Rye. (高句麗) tombs, visualization of sky with these animal constellations could have been established as early as in Go-Gu-Ryer Dynasty. We also reconstruct this ”A Sasin-animal Korean sky map” based on the shapes of the Sasin and Ki-Rin from Go-Gu-Ryer paintings and 28 oriental constellations in Chon- S an g- Yol- C h a- B un- Ya- J i- Do.

  • 불어의 "묵음 e(e muet)"에 대한 정의를 내리기는 매우 까다롭다. 불어에서 "e"가 "묵음 e(e muet)"로 불리우는 이유는 "e"가 흔히 탈락되기 때문이다. 현재 "e muet"는 다음 발화체에서 볼 수 있듯이 열린음절에서만 나타난다. "Je/le/re/de/man/de/ce/re/por/ta/ge/." [omitted](나는 그 리포트를 다시 요구한다. : 이 경우 실제 발화시 schwa 삭제 규칙이 적용된다.) 둘째, 접두사에 나타나는 "e muet"는 s의 중자음 앞에서 s가 유성음, [z]로 발음되는 것을 막기 위해 쓰인다. "ressembler[omitted](닮다); ressentir[omitted](느끼다)" 같은 경우, 셋째, 몇몇 낱말의 경우 고어의 철자가 약화되어 "e muet"로 발음이 되고 있다. "monsieur[$m{\partial}sj{\emptyset}$](미스터), faisan[$f{\partial}z{\tilde{a}}$](꿩), faisait[$f{\partial}z{\varepsilon}$]("하다"동사의 3인칭 단수 반과거형)"등. 또 과거 문법학자들은 이를 "여성형의 E"로 불렀는데, 이는 형태론적으로 낱말의 여성형을 남성형과 구분짓기 위해 사용되고 있기 때문이기도 하다. 예를 들어, "$aim{\acute{e}}-aim{\acute{e}}e$"(발음은 둘 다 [${\varepsilon}me$]로 동일하다 : 사랑받다)의 경우. 현대불어의 구어체어서 "e muet"는 어말자음을 발음하기 위해 쓰이고 있다. 예를 들어, "pote[pot](단짝)-pot[po](항아리)". 이러한 "e muet"는 발음상으로 지역적, 개인적 및 문맥적 상황에 따라 그 음색 자체가 매우 불안정하며 여러 가지 음가(열린 ${\ae}$ 또는 닫힌 ${\O}$)로 나타난다. 예를 들어 "seul[$s{\ae}l$](홀로), ceux[$s{\O}$](이것들)"에서와 같이 발음되며, 또한 원칙적으로 schwa, [${\partial}$]로 발음이 되는 "Je[$\Im\partial$]"와 "le[$l{\partial}$]"의 경우, Paris 지역에서는 "Je sais[${\Im}{\ae}{\;}s{\Im}$](나는 안다); Prends-le[$pr{\tilde{a}}{\;}l{\ae}$](그것을 집어라)"로 발음을 하는 한편, 프랑스 북부 지방세서는 동일한 발화체를 [${\ae}$]대신에 [${\o}$]로 발음한다. 실제로 언어학적 측면에서 고려되는 "e muet"는 schwa로 나타나는 "Je[$\Im\partial$]"와 "le[$l{\partial}$]"의 경우인데, 불어 음운론에서는 schwa에 의해 대립되는 낱말짝이 없기 때문에 schwa를 음소로 인정할 것인가에 대해 논란이 있다. 그러나 불어에서 schwark 음운론적 역할을 한다는 사실은 다음과 같은 예에서 찾아 볼 수 있다. 첫째, 발음상으로 동사의 변화형에서 "porte[$p{\jmath}rte$](들다: 현재형), porte[$p{\jmath}rte$](과거분사형), porta[$p{\jmath}rte$](단순과거형)"등이 대립되며, 이휘 "Porto[$p{\jmath}rte$](포르토)"와도 대립된다. 둘째, 어휘적 대립 "le haut[$l{\partial}o$](위)/l'eau[lo](물)"와 형태론적 대립 "le[$l{\partial}$](정관사, 남성단수)/les[le](정관사, 복수)"등에서 "묵음 e"는 분명히 음운론적 역할을 하고 있다. 본 논문에서는 이와 같이 음색이 복잡하게 나타나는 "e muet"의 문제를 리듬단위, 문맥적 분포 및 음절모형 측면, 즉 음성학 및 음운론적 측면에서 다양하게 분석하여 그 본질을 규명해 보고 "e muet"탈락현상을 TCG(Theorie de Charme et de Gouvernement) 측면에서 새롭게 해석해 보았다.

  • Since the failure behavior of transversely isotropic rocks is significantly different from that of isotropic rocks, it is necessary to develop a transversely isotropic rock failure function in order to evaluate the stability of rock structures constructed in transversely isotropic rock masses. In this study, a spatial distribution function for strength parameters of transversely isotropic rocks is proposed, which is based on the Cassini oval curve proposed by 17th century astronomer Giovanni Domenico Cassini to model the orbit of the Sun around the Earth. The proposed distribution function consists of two model parameters which could be identified through triaxial compression tests on transversely isotropic rock samples. The original Mohr-Coulomb (M-C) failure function is extended to a three-dimensional transversely isotropic M-C failure function by employing the proposed strength parameter distribution function for the spatial distributions of the friction angle and cohesion. In order to verify the suitability of the transversely isotropic M-C failure function, both the conventional triaxial compression and true triaxial compression tests of transversely isotropic rock samples are simulated. The predicted results from the numerical experiments are consistent with the failure behavior of transversely isotropic rocks observed in the actual laboratory tests. In addition, the simulated result of true triaxial compression tests hints that the dependence of rock strength on intermediate principal stress may be closely related to the distribution of the microstructures included in the rock samples.

  • Recently the demand for civil protection and security guards shows rapid growth by the social development and improve the quality of life. However the supply and education system have some limitations in spite of the high demand guard-secretary. The main role of secretaries has been to accompany superiors in order to maintain their dignity or trait. However, the secretaries are required to play additional roles of safety managers such as a security manager, a protocol manager, an intelligence manager and a protective driver in order to overcome the domestic and the international safety environment and to elevate the quality of service as a competitive work. Therefore, the purpose of this article is to analyse current situation of curriculum on security guard training at the universities related to this department, and to seek an educational model for this area. For that, the following questions will be examined. First, Do the professional training organizations meet social demand for the body and security guards? Second, What kind of training has to be provide for the body and security guards? and what the qualifications of the trainers? Then, what are the differences in training courses between private organizations and universities? Is there differences in the job placement among the trainers of private organizations and universities? etc.. In summary to meet the social demand common curriculum for the body and security guard will be drawn from the analyses of diverse training organizations with different training courses in contents, training periods, educational value, and social aim. For the scholarly identity to the security and secretary studies is th following on the core curriculum, then the university curriculum is very important for that. It is need to arrange the curriculum that is actually current at College or University for the suggestions on scholarly identity and development of the security and secretary studies.

  • October 31, 2017, a man named Saipov who follows ISIS killed 8 people and injured nearly 20 others by driving his truck to the riverside bicycle path in Manhattan, New York, in an act of terror. June 5, 2017, the Islamic extremist Yacqub Khayre held a woman hostage in a suburb of Melbourne, Australia, before being killed by the police. Various countries around the world including the UK, France, and Germany are in war against terrorism. The terrorists change their target from hard targets such as government officials to vulnerable soft target, intensifying the public's fear, and, unlike in the past when they were organized by governments or organizations, extremists such as ISIS followers are now acting on their own in the act of terrorism. Also, as they use vehicles, pressure cooker, and other objects that can be easily found for terrorism, it is becoming more difficult for the police to prepare against terrorist attacks. Meanwhile, some terrorism researchers argue that conversational techniques (negotiation) used by the police are now of no use, as shown in the cases like 9/11 attacks in 2001 and 2016 Nice attack in France in which the suspects committed terrorist attacks without leaving enough time for the police to take action and that, therefore, tactical suppression techniques need to be developed. Therefore, this study suggested police negotiation techniques are necessary not only for terrorist attacks but also for overall police work, including handling intoxicated people at police station, and proposed ways to activate conversational techniques for police organizations.

  • In an attempt to evaluate the current research status of genetically modified (GM) plants, the scientific research publications in Korea as well as in international SCI journals were screened. About 190 research articles related to the development of GM plants were searched from 10 different domestic journals in the last 12 years (Jan. 1990 to Sept. 2002), The researches in 65 articles were carried out with tobacco plant, 20 with rice, 19 with potatoes, and less then 9 articles from each other plant species, respectively, In total, 38 different plant species were being subjected for the development of GM plants. In particular, there was only one article for each major staple grains such as wheat, barley, soybean, and maize. In more than 47% of total published articles, scientists mainly focused on the basic research such as developing transformation system (46 articles), gene expression study in transgenic plants (34), and vector constructions (10). In addition, 28 articles which main authors are Korean scientists were searched from 11 different international SCI journals. Again, major plants for GM research were tobacco (10) and rice (7). More than 50% of published articles were focused on the basic research, gene expression study with transgenic plants (16). The publications on the research of disease-resistant plants were 7 articles, 3 for the development of stress-resistant and 2 for the herbicide-resistant plants, respectively. It is believed that the last 10 year's investment through government organizations has just strengthen the capacity for the next big stride on agricultural biotechnology in Korea.
