Heungdukwang'(興德王) costume ordinance(834A.D.) is a very important written historical record because it reveals Tongil Shills's(統一新羅) costume. But among the clothing pieces that appeared in Heundukwang'(興德王) costume ordinance, classification of Naeoe(內衣) and Danoe(短衣) is not clear. This study focuses on the categorization of Naeoe(內衣) and Danoe(短衣). Upper garments included among costume ordinance were Pyooe(表衣), Naeoe(內衣) and Danoe(短衣), Pyooe(表衣) and aeoe(內衣) were unisex, while Danoe(短衣) was worn only by women excluding the lower class. Pyooe(表衣) is applicable to Po(袍), Naeoe(內衣) is aplicable to Yu(유). Shilla'(新羅) upper garments appearing in visual records are as follows: -With the exception of Pyooe(表衣), the length of men's upper garments were between hip and knee length. These upper garments featured V-neck and round neck styles with the left side of the garments folded over the right side. -Again excluding Pyooe(表衣), women's upper garments were similar to men's upper garments having V-neck and round necklines. We know this to be true from the relics found during the excavations of Hwangsungdong and Yonggangdong, as well as from the women in the stone reliefs of Sangju. Although we know the shape of necklines. the length of upper garments remained a mystery because women of that tome tucked in their upper garments into the skirts and/or wore an over garment. However a clay doll found around Bulguksa(佛國寺) wearing a knee length garment with V-neck. The upper garment was opened in the front and was worn over another garment with same length and round neckline. At that time, The upper garments found in China and Japan. were not much different than those found in Shilla (新羅). They also included garments that were waist length, had peach-shaped necklines, or were worn over head. Shilla's(新羅) traditional upper garment was between hip and knee length, but with the introduction and influence of Chinese costume. upper garments with a length coming down to the high waist line began to appear. In addition to Chinese influence, because Shilla's(新羅) women wore the upper garment first and then the lower garment, a long upper garment was not necessary. These shorter upper garments came to be known as 'Danoe(短衣)'When we perceive clothing. we look at silhouette first and then the details. Silhouette is much determined by length and neckline or the front of the garment determines the details, So we need to attention to the basis of ancient dress classifications. These classifications were according to first length [Po(袍), Yu(유)] and then neckline [Danryoung(團領), Jingryoung(首領)]. As a result. Naeoe(內衣) and Danoe(短衣) are classified by the length. The length (內衣) was between hip and knee length while Daneoe(短衣) was waist length. Danoe(短衣) was worn by putting the bottom of it inside skirt naeoe(內衣) was worn over a skirt or plant. But both had V-neck and round neck styles, and styles with the left side of the garments folded over the right side.

This study was to gain a suggestion how to educate the science gifted student and manage the science gifted education center by analyzing the science gifted student's perception of the science, scientist and vocation. One seventy and eight science gifted students were involved in the questionnaire to investigating the perception of science, scientist and vocation. As the results, many of science gifted students thought the convenience as the positive aspect of science and the environmental pollution as the negative aspect of science. Science gifted students considered most scientists a diligent person, researcher and what's more, they are careless about home. They suggested much more of foreign scientists like Einstein, Edison, etc. than Korean ones as respectable scientists. Scientist is a major vocation that they want and know in the science area, while some students want to be a doctor, occurred to science singer. The mystery, difficulty, complexity, scientist, etc. occurred to science gifted students when they heard the ‘science’. According to the results, there are in need of the new educational programs for the science gifted students and science gifted education center. One of the aims of the science gifted education center is the judgment and cultivation of the science gifted student. Therefore, the science gifted student to be educated to improve positively the images of science and scientist. In addition to, they should get a concern about the vocation in science area and to be a famous scientist.

It has been a big mystery what drives filament eruptions and flares. We have studied in detail an X1.8 flare and its associated filament eruption that occurred in NOAA Active Region 9236 on November 24,2000. For this work we have analyzed high temporal (about 1 minute) and spatial (about 1 arcsec) resolution images taken by Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory, Hoc centerline and blue wing ($-0.6{\AA}$) images from Big Bear Solar Observatory, and 1600 ${\AA}$ UV images by the Transition Region and Corona Explorer (TRACE). We have found that there were several transient brightenings seen in H$\alpha$ and, more noticeably in TRACE 1600 ${\AA}$ images around the preflare phase. A closer look at the UV brightenings in 1600 ${\AA}$ images reveals that they took place near one end of the erupting filament, and are a kind of jets supplying mass into the transient loops seen in 1600 ${\AA}$. These brightenings were also associated with canceling magnetic features (CMFs) as seen in the MDI magnetograms. The flux variations of these CMFs suggest that the flux cancellation may have been driven by the emergence of the new flux. For this event, we have estimated the ejection speeds of the filament ranging from 10 to 160 km $s^{-1}$ for the first twenty minutes. It is noted that the initiation of the filament eruption (as defined by the rise speed less than 20 km $s^{-1}$) coincided with the preflare activity characterized by UV brightenings and CMFs. The speed of the associated LASCO CME can be well extrapolated from the observed filament speed and its direction is consistent with those of the disturbed UV loops associated with the preflare activity. Supposing the H$\alpha$/UV transient brightenings and the canceling magnetic features are due to magnetic reconnect ion in the low atmosphere, our results may be strong observational evidence supporting that the initiation of the filament eruption and the preflare phase of the associated flare may be physically related to low-atmosphere magnetic reconnection.

Seok-Jung Choi's Jisuguimundo mentioned as a brilliant legacy in the history of Korean mathematics had been cloaked in mystery for 300 years. In the meantime there has been some efforts to find solutions, and some particular answers were found, but no one achieved full success mathematically. By the way, H-alternating method showed that to find solutions of Jisuguimundo is possible, even though that method restricted magic number to 88~92 and 94~98. In this paper, $n{\times}n$ Jisuguimundo is defined, and it is showed that finding solutions of it is always possible in case of partition $({\upsilon}+1)+{\upsilon}+({\upsilon}+1)$ & co-partition ${\upsilon}+({\upsilon}+1)+{\upsilon}$, partition $({\upsilon}+1)+({\upsilon}-1)+({\upsilon}+1)$ & co-partition $({\upsilon}-1)+({\upsilon}+1)+({\upsilon}-1)$, partition $({\upsilon}+1)+({\upsilon}+2)+({\upsilon}+1)$ & co-partition $({\upsilon}+2)+({\upsilon}+1)+({\upsilon}+2)$, and partition $({\upsilon}+1)+({\upsilon}+3)+({\upsilon}+1)$ & co-partition $({\upsilon}+3)+({\upsilon}+1)+({\upsilon}+3)$. And It is suggested to find solutions of $n{\times}n$ Jisuguimundo could be used as a task for problem solving.

A purpose of this research is to find out characteristic of bronze artifacts and gold ornaments excavated from Xiongnu tombs No. 2~4 at Duurlig Nars in Mongolia through scientific analysis of them. The Tombs are comparatively small. There were still lots of relics remaining although the tombs had been already robbed. Also the tombs are evaluated important since the origin of them show coexisting of chinese and northern style. First of all, an analysis result about bronze vessels found in this site, they have high lead(Pb) content and relatively low tin(Sn) content, as compared with the Bronze Han Mirror and End-fittings of Bronze Parasol Rib. Especially in case of bronze tray and bronze lamp from the no. 2 tomb and also bronze cauldron from the no. 4 tomb contain only 1wt% of tin which means binary alloy composition(Cu-Pb). Also, in the case of gold ornaments found in the no. 2 tomb, they have comparatively high purity. And the research suppose that the high possibility of that they were used soldering using alloy of Au-Cu or diffused bonding(using malachite and copper oxide) for joining gold grains of gold granulation ornament. Further scientific research and analysis in Mongolia and other countries will provide more clues to solve mystery of Xiongnu culture.

Motility and chemotaxis are crucial for disease development in many motile pathogens, including spirochetes. In many bacteria, motility is provided by flagella rotation, which is controlled by a chemotaxis-signal-transduction system. Thus, motility and chemotaxis are inextricably linked. Spirochetes are a unique group of bacteria with distinctive flat-wave morphology and corkscrew-like locomotion. This unusual motility pattern is believed to be important for efficient motility within the dense tissues through which these spirochetes preferentially disseminate in a host. Unlike other externally flagellated bacteria-where flagella are in the ambient environment-the flagella of spirochetes are enclosed by the outer membrane and thus are called periplasmic flagella or endoflagella. Although motilityand chemotaxis-associated genes are well studied in some bacteria, the knowledge of how the spirochete achieves complex swimming and the roles of most of the putative spirochetal chemotaxis proteins are still elusive. Recently, cutting-edge imaging methods and unique genetic manipulations in spirochetes have helped to unravel the mystery of motility and chemotaxis in spirochetes. These contemporary advances in understanding the motility and chemotaxis of spirochetes in a host's persistence and disease process are highlighted in this review.

This study looked for employment services satisfaction surveys done in the UK, USA and Korea. And through which derived the following suggestions for improving Korea the employment service satisfaction survey. First, in terms of research design improvements to ensure the representativeness of the sample region for each center and branch-specific (job seekers and recruiters) requires the sampling design based on user scale. In addition, the sample design should be applied when considering specific user can be distributed. US is restricted to participants within 60 days for sampling and sample extraction once a month at least. Next in terms of survey improvements, it is necessary to apply a weighting part considering the regional characteristics. For this, the correct analysis of the employment center by the internal and external environment is required. And in the case of non-face-to-face service, complaints about worknet use is likely to be channeled into complaints about job centers provide services. It needs to improve on this. And for the improvements of business processes service by an in-depth study, it can be seen to review the possible introduction of a British mystery shopper.

Due to its unique formation and mystery phenomena, comets is a major motif that inspires various creative fields. Media art that has been developed and expanded in step with the development of modern scientific technology has expressed the unique characteristics of comets such as their structure in the art as a motif, using technologies. This study describes the process of producing "Near by", an distance-recognition interactive media art. offering the audience a chance to create a tail of a comet as they close to it. changes the color of a LED structure representing the nucleus of a comet as the audience approaches it. At the same time, a video of a comet's tail is projected. Through this interaction, the audience will renew their perception on comets and emotionally interact with the art. This work capturing not only the formative characteristics of a comet, but also its forming process as a motif. Such composite way of expressing a motif could be presented as a possibility of extending the expression of the natural phenomenon in the future media art field.

"To be, or not to be?" This question is not only Hamlet's agony but also the dilemma of mitochondria in a cancer cell. Cancer cells have a high glycolysis rate even in the presence of oxygen. This feature of cancer cells is known as the Warburg effect, named for the first scientist to observe it, Otto Warburg, who assumed that because of mitochondrial malfunction, cancer cells had to depend on anaerobic glycolysis to generate ATP. It was demonstrated, however, that cancer cells with intact mitochondria also showed evidence of the Warburg effect. Thus, an alternative explanation was proposed: the Warburg effect helps cancer cells harness additional ATP to meet the high energy demand required for their extraordinary growth while providing a basic building block of metabolites for their proliferation. A third view suggests that the Warburg effect is a defense mechanism, protecting cancer cells from the higher than usual oxidative environment in which they survive. Interestingly, the latter view does not conflict with the high-energy production view, as increased glucose metabolism enables cancer cells to produce larger amounts of both antioxidants to fight oxidative stress and ATP and metabolites for growth. The combination of these two different hypotheses may explain the Warburg effect, but critical questions at the mechanistic level remain to be explored. Cancer shows complex and multi-faceted behaviors. Previously, there has been no overall plan or systematic approach to integrate and interpret the complex signaling in cancer cells. A new paradigm of collaboration and a well-designed systemic approach will supply answers to fill the gaps in current cancer knowledge and will accelerate the discovery of the connections behind the Warburg mystery. An integrated understanding of cancer complexity and tumorigenesis is necessary to expand the frontiers of cancer cell biology.

Recognizing a basal group in a taxon is one of the most important factors involved in understanding the evolutionary history of that group of life. Many botanists have suggested a sister to all other angiosperms to understand the origin and rapid diversification of angiosperms based on morphological and fossil evidence. Recent technical advances in molecular biology and the accumulation of molecular phylogenetic data have provided evidence of the extant basal-most angiosperm which is a sister to all other angiosperms. Although it is still arguable, most plant taxonomists agree that Amborella trichopoda Baill., a species (monotypic genus and monotypic family) distributed in New Caledonia, is a sister to all other extant angiosperms based on evidence from the following molecular approaches: 1) classical phylogenetic analyses based on multiple genes (or DNA regions), 2) analyses of a tree network of duplicated gene families, and 3) gene-structural evidence. As an alternative hypothesis with relatively minor evidence, some researchers have also suggested that Amborella and Nymphaeaceae form a clade that is a sister to all other angiosperms. Debate regarding the basal-most angiosperms is still ongoing and is currently one of the hot issues in plant evolutionary biology. We expect that sequencing of the whole genome of Amborella as an evolutionary model plant and subsequent studies based on this genome sequence will provide information regarding the origin and rapid diversification of angiosperms, which is Darwin's so called abominable mystery.
