The purpose of this study is to link traditional patterns to man's fashion goods design. Of all the traditional patterns, the bat pattern was chosen for use during the development of a man's fashion goods design as like as neck-tie, pocketchief and scarf. This study is based upon document searches, including research papers. Thought these searches, it investigates the form of traditional bat patterns, tessellation which can be found easily in the Islamic culture as well as in tile and carpet patterns and a modern painting by Gustav Klimt(1862-1918). Based on this investigation, the study attempt to modernize the bat pattern and apply the neck-tie, pocketchief and scarf. The design procedure includes three sub-processes: selection, arrangement and color-scheme. In conclusion, six designs of man's fashion goods were created by using one of Korea's traditional patterns - the bat pattern. Therefore, this study offer invaluable suggestions for multifaced research on how to come up with design concepts which apply Korea's traditional patterns to Man's fashion goods design.

We, in this thesis, examined the similarities and differences of bat patterns in China and Korea, along with a consideration of how two peoples understood bats and how their understanding of bats developed and also influenced the bat patterns. As for research period, the Ming(明) dynasty and the Qing(淸) dynasty in China and the Chosun dynasty in Korea were considered. The subjects of this study included clothes, personal ornaments, and embroidery. This research was done by comparing and analyzing the similarities and differences of two countries' bat patterns. The results of comparing and analyzing Chinese and Korean bat patterns were as follows: In terms of similarity, people of two countries understood bat patterns as the symbol of happiness. Therefore, they were used in clothes, personal ornaments, and daily necessities. In terms of difference, bat patterns of two countries had different shapes. In China, colorful and realistic single bat patterns were shown as intensive composition, whereas in Korea plain and simple bat patterns were used. These differences resulted from different way of understanding of bat patterns. It can be concluded that the bat patterns can be a great cultural commodity with high commercial values, if the traditional pattern is used as a unique element of the Oriental designs and altered and developed to attract consumers' attention.

ZnO crystals with a baseball bat shape were synthesized without any catalysts through a simple thermal oxidation of ZnS powder in alumina crucible under air atmosphere. SEM images demonstrated that the bat structure was composed of two pieces of ZnO crystals, i.e hexagonal-shaped rod and inverted cone-shaped rod. X-ray diffraction (XRD) pattern revealed that the ZnO crystals had wurtzite hexagonal structure. Energy dispersive X-ray (EDX) spectrum showed that the ZnO was of high purity. A strong green emission peak at 510 nm was observed in cathodoluminescece spectrum.

Parvalbumin occurs in various types of cells in the retina. We previously reported parvalbumin distribution in the inner nuclear layer of bat retina. In the present study, we identified the parvalbumin-immunoreactive neurons in the ganglion cell layer of the retina of a bat, Rhinolophus ferrumequinum, and investigated the distribution pattern of the labeled neurons. Parvalbumin immunoreactivity was found in numerous cell bodies in the ganglion cell layer. Quantitative analysis showed that these cells had medium to large-sized somas. The soma diameter of the parvalbumin-immunoreactive cells in the ganglion cell layer ranged from 12.35 to 19.12 ${\mu}m$ (n=166). As the fibers in the nerve fiber layer were also stained, the majority of parvalbumin-immunoreactive cells in the ganglion cell layer should be medium to large-sized retinal ganglion cells. The mean nearest neighbor distance of the parvalbumin-immunoreactive cells in the ganglion cell layer of the bat retina ranged from 59.57 to 62.45 ${\mu}m$ and the average regularity index was 2.95 ${\pm}$ 0.3 (n=4). The present results demonstrate that parvalbu-min is expressed in medium to large-sized retinal ganglion cells in bat retina, and they have a well-or-ganized distributional pattern with regular mosaics. These results should be important as they are applicable to a better understanding of the unsolved issue of a bat vision. This data will help to provide fundamental knowledge for the better understanding of the unique behavioral aspects of bat flight maneuverability.

버퍼 오버플로우 취약점은 자체적으로 외부코드를 실행시키거나 다른 취약점과 연계해 공격될 수 있는 취약점으로 이를 탐지하기 위해 많은 연구들이 진행되었다. 기존의 버퍼 오버플로우 취약점 탐지기법에 대한 연구는 취약함수를 검색하거나 동적오염분석으로 얻은 비 신뢰 데이터의 흐름을 감시하여 취약함수로 전파되는 걸 탐지하는 방식 이었다. 하지만 이러한 기법은 다양한 한계를 가진다. 본 논문은 이러한 문제들을 해결하기 위해 버퍼 오버플로우가 발생하는 기계어 패턴을 BBL단위로 감시하고, 비 신뢰 데이터의 흐름을 추적하여 기존의 탐지 사각지대를 없애는 방법을 제안한다.

In this study, we analyzed the pulse-duration, pulse-interval and peak-frequency of echolocation call in three species as Rhinolophus ferrumequinum, Pipistrellus abramus, and Myotis macrodactylus. The peak frequency and pulse duration for above mentioned species were 69 kHz, 47 kHz and 49 kHz and $69.39{\pm}8.76\;ms$, $4.95{\pm}0.77\;ms$ and $3.09{\pm}0.48\;ms$ for R. ferrumequinum, P. abramus and M. macrodactylus, respectively. The pulse intervals for R. ferrumequinum, P. abramus and M. macrodactylus were $103.61{\pm}9.05\;ms$, $67.59{\pm}3.47\;ms$ and $66.35{\pm}4.96\;ms$, respectively. The pulse pattern of R. ferrumequinum was setting into a short FM call and linked to long CF call and went through the short FM call again. The pulse pattern of M. macrodactylus was comprised with serial short FM call and the CF call was not checked up in accordance with the spectrogram analysis. The long FM call and short CF call got join together for the P. abramus and the peak frequency was checked up at the pulse ending as CF call.

Although the physiological roles of calretinin have not been established, it may simply work as a calcium buffer or may actively work in calcium-mediated signal transduction. Calretinin plays a little role in the transport and physiological buffering of calcium in the adult photoreceptor cells, bipolar cells and horizontal cells of the human retina. We identified the calretinin-immunoreactive neurons in the inner nuclear cell layer and ganglion cell layer and the distribution pattern of the labeled neurons in the retina of a bat, Rhinolophus ferrumequinum, in this study. We observed the existence of calretinin-immunoreactive AII amacrine cell in the inner nuclear layer and ganglion cells in the ganglion cell layer of bat retina through this study. This observation must be significant along with our previous studies as we need to study for more understanding about the unsolved issue of a bat vision and the unique behavioral aspects of bat flight maneuverability.

This thesis is focused on the bat symbol, especially prevalent crafts’ pattern in late Joseon period on museum collections. For the use and reperception of them, I am aimed for appropriate analysis of bat symbol by co connotation which reflects the characteristics on number.plastic.color symbol. This point of view, bat idea and bat paintings in Joseon period will be the source of meanings to the denotation of bat patterns. In the museum collections, bat paintings and patterns are calculated 324 objects. By functional classification, the bat patterns on dwelling-crafts for the royal and for the people will be discussed. In result, the bat paintings were only a few, however, usually connoted Taoist hermit with super-natural powers.longevity.protector of Lightning-God.praying for long life, which were based on Taoism. Meanwhile the bat symbol of dwelling-crafts for the royal projected the longevity and prosperity of king and queen. By he Five Blessings and good auspices in Ching dynasty, number of '5.4' implied 'Five Blessings', Through the correct recognition of homo-phone, "a bat(蝠, fu)=happiness(福, fu)$\rArr$five bats(五蝠)$\rArr$Five Blessings(五福 )." In the case of bat symbol on the dwelling-crafts for the people, especially its for women, it expressed on the metal-decoration of furniture and paper-crafts. In the metal-decoration, the signified of bat symbol were expellant-evil('guard') that of characteristic signifier, white-silver color, number '1' and 'flying-type'. The bat symbol on paper-crafts for the people signified 'double happiness'.harmony.sons with number of '2', 'Five Colors' and the transformation of 'flying-type'. Accordingly, the bat symbol on the dwelling-crafts for the people marked 'happiness and guard', because the people had concrete cognition the bat symbol as a denotation of 'happiness and 'guard' by itself

The current study investigated whether Korean learners' English-learning environments, especially target English accent (General American English (GAE) vs. Southern British English (SBE)) and English-language experience affected their production of English vowels. Thirty six EFL learners, 27 ESL-US learners, and 33 ESL-UK learners produced 8 English vowels with a bVt frame (beat, bit, bet, bat, bought, bot, boat, boot). The learners' productions were acoustically analyzed in terms of F1 and F2 frequencies. The overall results revealed that the learners' target accent had an effect on their production of some English vowels. The EFL and ESL-US learners' (especially, female learners') production of bought, bot, boat, and boot, which show characteristic differences between the GAE and SBE accents, was closer to that of the native American English (AE) speakers than the native British English (BE) speakers. In contrast, the ESL-UK learners' production of bought and bot demonstrated the opposite pattern. Thus, the impact of target accent was not demonstrated across the board. The effect of the learners' different English-language experience was also rather limited. This was because the EFL learners' production was not much different from the ESL-US learners' production, in spite of the ESL-US learners' residence in the US for more than 9 years. Furthermore, the Korean learners, irrespective of their different English-language experience, tended to produce bit and bat with lower F1 than the native AE and BE speakers, thus resulting in bit and bat to be produced similarly to beat and bet, respectively. This demonstrates the learners' persistent L1 effects on their English vowel production despite the learners' residence in the English speaking countries or their high English proficiency.

Echolocation call structure and intensity were measured from the Malaysian Myotis muricola, which were recorded from the hand-released bat. The Malaysian M. muricola produced typical FM call pattern of the genus Myotis, producing steep, downward frequency-modulated calls. The average PF of calls is $64.39{\pm}1.33(kHz)$. Discrete PF patterns of two types are found, which consist of 63.39 kHz and 66.15 kHz. The averages of SF and D are $126.07{\pm}3.37kHz$ and $2.14{\pm}0.29ms$, respectively. There are various IPI lengths with average of $42.97{\pm}12.68ms$. A pulse consists of two harmonies which consist of the first harmony with wider bandwidth and the second harmony with narrower bandwidth. The PF of the first harmony is higher than that of the second harmony. The typical FM call structure, with two harmonies and wide bandwidth, would be highly related to fast flying and wide screening in the dense forests.
