팻 메스니는 1976년도에 데뷔한 이후 현재까지 장르를 재즈에 국한하지 않고 다양하고 실험적인 음악으로 대중에게 어필하였다. 50여장에 이르는 그의 앨범들은 그래미상(Grammy Award)를 20차례나 수상하였고, '골드 디스크(Gold Disc)' 상을 3차례나 수상할 정도로 '예술성'과 '음악성'을 인정받았다. 이러한 이유로 그의 음악은 단순히 재즈라는 한 단어로 표현하기는 힘들다. 기초 화성학에서는 기본적으로 메이저 코드에서 사용하는 스케일과 마이너 코드에서 사용하는 스케일이 정해져 있다. 예를 들어 메이저 코드에서는 Ionian Scale이나 Lydian 스케일을 주로 사용하고, 마이너 코드일 때는 Dorian Scale이나 Phrygian Scale, 그리고 Aeolian Scale을 주로 사용한다. 또 m7b5 코드 일 때는 당연히 Locrian Scale을 사용하는 것이 일반적이다. 하지만 팻 메스니의 스케일을 분석한 결과 메이저 코드일 때 Dorian Scale을 사용한다던지, 또 마이너 코드일 때 Lydian Scale을 사용하여 Lick을 만들었다. 그리고 도미넌트 코드 일 때 사용하는 여섯 가지 스케일도 다양하게 사용하지만 의외로 Dorian Scale이나 Lydian Scale을 자주 사용하는 것을 알 수 있었다. 그리고 어떤 마디에서는 Ionian Scale과 Aeolian Scale을 같이 사용하여 Lick을 만들었는데, 이런 경우에는 그 마디의 전체적인 느낌이 메이저의 밝은 느낌과 마이너의 어둡고 쓸쓸한 느낌을 동시에 표현하기 때문에 아주 독특한 분위기를 연출하기도 한다. 또 블루스의 열두 마디 패턴을 빌려와서 사용하면서 블루스 스케일은 사용하지 않고 Ionian Scale과 Lydian Scale, Mixo-Lydian Scale을 주로 사용하여 Lick을 만드는 스타일을 보여 주기도 하였다.

In recent emerging industry, Display field becomes bigger and bigger, and also semiconductor technology becomes high density integration. In Flat Panel Display, there is an issue that electrostatic phenomenon results in fine dust adsorption as electrostatic capacity increases due to bigger size. Destruction of high integrated circuit and pattern deterioration occur in semiconductor and this causes the problem of weakening of thermal resistance. In order to solve this sort of electrostatic failure in this process, Soft X-ray ionizer is mainly used. Soft X-ray Ionizer does not only generate electrical noise and minute particle but also is efficient to remove electrostatic as it has a wide range of ionization. X-ray Generating efficiency has an effect on soft X-ray Ionizer affects neutralizing performance. There exist variable factors such as type of anode, thickness, tube voltage etc., and it takes a lot of time and financial resource to find optimal performance by manufacturing with actual X-ray tube source. MCNPX (Monte Carlo N-Particle Extended) is used for simulation to solve this kind of problem, and optimum efficiency of X-ray generation is anticipated. In this study, X-ray generation efficiency was measured according to target material thickness using MCNPX under the conditions that tube voltage is 5 keV, 10 keV, 15 keV and the target Material is Tungsten(W), Gold(Au), Silver(Ag). At the result, Gold(Au) shows optimum efficiency. In Tube voltage 5 keV, optimal target thickness is $0.05{\mu}m$ and Largest energy of Light flux appears $2.22{\times}10^8$ x-ray flux. In Tube voltage 10 keV, optimal target Thickness is $0.18{\mu}m$ and Largest energy of Light flux appears $1.97{\times}10^9$ x-ray flux. In Tube voltage 15 keV, optimal target Thickness is $0.29{\mu}m$ and Largest energy of Light flux appears $4.59{\times}10^9$ x-ray flux.

연구목적: 임플란트는 수직교합 하중에는 비교적 잘 견디나 측방하중에 대해서는 약한 역학적 성질을 갖고 있으므로 임플란트의 재료 특성과 기하학적 형태에 따른 응력 분석 연구의 필요성이 제기되고 있다. 연구재료 및 방법: 외부육각구조를 갖는 28개의 임플란트를 7개씩 4군으로 나누어 그 제품에 적합한 UCLA gold abutment를 이용해, 제3형 금합금으로 보철 물을 제작하였고, A군 (3i, FULL $OSSEOTITE^{(R)}$-Implant), B군 (Nobelbiocare, Branemark $System^{(R)}$Mk III Groovy RP), C군 (Neobiotec, $SinusQuick^{(TM)}$ EB), D군 (Osstem, US-II)으로 분류하였다. 고정체와 지대주나사, 지대주를 연결한 후 수직적으로 절단하여 연마한 후 미세경도계를 이용하여 10군데에서 경도측정을 실시하였고, 동적하중 피로시험기를 이용하여 60-600 N범위로 파절시까지 동적 하중을 가하였다. 주사전자현미경을 이용하여 지대주나사 및 고정체의 파절 양상과 파절 위치 등을 관찰하였고, 유한요소분석을 통해 고정체와 지대주 나사에 나타나는 응력 분포와 파절면을 비교 분석하였다. 결과: 1.고정체 경도는 A, B, C, D군에서 각각 245.3, 289.7, 281.3, 300.4 Hv로 D군이 가장 높았고, A군이 가장 낮았다. 지대주 나사의 경도는 A, B, C, D군에서 각각 340.00, 317.62, 306.5, 306.2 Hv로 A군이 가장 높고, D군이 가장 낮았다. 2. 모든 실험군에서 임플란트 고정체의 파절은 응력이 집중되는 고정체 3-4번째 나사산 홈 (valley) 부위 또는 내면의 사공간부와 일치하는 부위에서 발생되었고, 피로수명은 A, B, C, D군에서 각각 31585, 47311, 30141, 105371로 D군이 가장 높았으며, A, B, C군과는 유의한 차이가 있었다(P<.05). 3. 파절양상은 B군과D군에서는 고정체와 나사 모두에서 수직 (longitudinal)파절과 수평 (transverse)파절이 동시에 일어나는 복합 (complex mode) 파절이 관찰 되었고, A와 C군에서는 고정체에서 수평 (transverse mode) 파절만이 관찰되었다. 4. 유한요소분석 결과 인장응력이 가장 높은 고정체 표면부에서 피로 균열이 시발되어 압축응력이 가장 높은 반대편 부위로 피로균열이 전파되었으며, 최대 유효 응력값은 C군이 가장 높았고, B군에서 가장 낮았다. 결론: 피질골 높이와 일치하는 임플란트 고정체 부위에서 최대 인장 주응력이 발생되며, 고정체 사공간부 (dead space)가 최대 인장 주응력이 작용하는 지그 표면과 일치할 때 피로파절이 발생되었다. 따라서 악골에 식립된 임플란트의 신뢰성을 향상시키고 수명을 증대시키기 위해서는 가능한 임플란트 주위의 골소실이 일어나지 않도록 해야 할 것이나 골흡수가 일어나 사공간부 수준까지 진행된다면 임플란트의 파절 빈도가 증가될 수 있으므로 이에 대한 대처가 필요할 것으로 사료된다.

Over the recent years, surface enhanced Raman spectroscopy (SERS) has dramatically grown as a label-free detecting technique with the high level of selectivity and sensitivity. Conventional SERS-active nanostructured layers have been deposited or patterned on rigid substrates such as silicon wafers and glass slides. Such devices fabricated on a flexible platform may offer additional functionalities and potential applications. For example, flexible SERS-active substrates can be integrated into microfluidic diagnostic devices with round-shaped micro-channel, which has large surface area compared to the area of flat SERS-active substrates so that we may anticipate high sensitivity in a conformable device form. We demonstrate fabrication of flexible SERS-active nanostructured substrates based on soft-lithography for simple, low-cost processing. The SERS-active nanostructured substrates are fabricated using conventional Si fabrication process and inkjet printing methods. A Si mold is patterned by photolithography with an average height of 700 nm and an average pitch of 200 nm. Polydimethylsiloxane (PDMS), a mixture of Sylgard 184 elastomer and curing agnet (wt/wt = 10:1), is poured onto the mold that is coated with trichlorosilane for separating the PDMS easily from the mold. Then, the nano-pattern is transferred to the thin PDMS substrates. The soft lithographic methods enable the SERS-active nanostructured substrates to be repeatedly replicated. Silver layer is physically deposited on the PDMS. Then, gold nanoparticle (AuNP) inks are applied on the nanostructured PDMS using inkjet printer (Dimatix DMP 2831) to deposit AuNPs on the substrates. The characteristics of SERS-active substrates are measured; topology is provided by atomic force microscope (AFM, Park Systems XE-100) and Raman spectra are collected by Raman spectroscopy (Horiba LabRAM ARAMIS Spectrometer). We anticipate that the results may open up various possibilities of applying flexible platform to highly sensitive Raman detection.

Laboratory workers, in resource-poor countries, still consider PCR detection of Giardia lamblia more costly and more time-consuming than the classical parasitological techniques. Based on 2 published primers, an in-house one-round touchdown PCR-RFLP assay was developed. The assay was validated with an internal amplification control included in reactions. Performance of the assay was assessed with DNA samples of various purities, 91 control fecal samples with various parasite load, and 472 samples of unknown results. Two cysts per reaction were enough for PCR detection by the assay with exhibited specificity (Sp) and sensitivity (Se) of 100% and 93%, respectively. Taking a published small subunit rRNA reference PCR test results (6%; 29/472) as a nominated gold standard, G. lamblia was identified in 5.9% (28/472), 5.2%, (25/472), and 3.6% (17/472) by PCR assay, $RIDA^{(R)}$ Quick Giardia antigen detection test (R-Biopharm, Darmstadt, Germany), and iodine-stained smear microscopy, respectively. The percent agreements (kappa values) of 99.7% (0.745), 98.9% (0.900), and 97.7% (0.981) were exhibited between the assay results and that of the reference PCR, immunoassay, and microscopy, respectively. Restriction digestion of the 28 Giardia-positive samples revealed genotype A pattern in 12 and genotype B profile in 16 samples. The PCR assay with the described format and exhibited performance has a great potential to be adopted in basic clinical laboratories as a detection tool for G. lamblia especially in asymptomatic infections. This potential is increased more in particular situations where identification of the parasite genotype represents a major requirement as in epidemiological studies and infection outbreaks.

This study identifies formativeness and the Korean consciousness of the vernacular design in a Korean designers' collection in order to discover the internal characteristics of vernacular expression elements. The study is based on a theoretical review and an analysis of cases collected from Korean fashion designers' clothes. Research is limited to international collections of clothes presented by Korean fashion designers since 2,000. The process of Korean vernacular designs in fashion were analyzed for formativeness in form, color, pattern and detail. The research findings identified formativeness and Korean's consciousness of modern fashion designs that reflect vernacular designs as follows. First, they are round, flexible line and shape based on assimilated with nature, rhythmic curve to express life force and asymmetry based on an ecstatic world based on nature. Second, a white color explained the pure mind and racial peculiarities in regards to the five colors that expressed the thinking of traditional rituals such as prayers for comfort of life and ancestor worship. Third, there were patterns around shape of nature, praying, and Korea culture. Finally, there were skills of Korean traditional handcrafts such as embroideries, knit-works, gold foils, and quilts where clothes expressed the hardship of life and strong willpower to overcome. In conclusion, the clothing of Korean vernacular designs contains characteristics such as natural beauty, decorativeness, shamanism, and eclecticism.

This study focused on the accessory of clothes of minority groups in Yunnan province to further the research about specific accessories' development in the future. Among the minorities in Yunnan, this study centralized characteristics of ornaments, hats and belts among five minority groups such as the Bai, Zhuang, Hani, Dai, and the Zang as representatives to study in detail because these five ethnicities have a relatively long history and plentiful information. The results are as follows: First, exaggeration means large gorgeous patterns that attract attention. Generally, there are many natural resources that can be used in places where these minority groups live such as gems, gold, silver shells and animals' horns, bone, teeth and the like. Headdress includes combs, loops, hairpins and other similar articles. Second, nature is a very fundamental part that people rely on for existence and development. The production and living that people need in life all depend on nature. The design of accessories is made from animal forms and patterns of clothes are presented through embroidery and wax printing. Designers always tried to add natural elements to their works. Third, symbolism consists of two aspects: One is the people's imagination, which related to actual materials, and the other is the product of imagination that provides better conditions to inspire people when they design. In China, most minority groups believe in Buddhism. The symbols in the clothing show their devout faith. Even the method of wear has many special implications like the use of accessories and length of clothing. The pattern of dragons and use of golden, red and other colors all have a proper symbolic significance in modern designs.

Transparent Sn-doped $In_2O_3$ (ITO) single-layer and ITO/Au/ITO multilayer films were deposited on glass substrates by reactive magnetron sputtering to compare the properties of the films. They were then annealed in a vacuum of $1{\times}10^{-2}\;Pa$ at temperatures ranging from 150 to $450^{\circ}C$ for 20 min to determine the effect of the annealing temperature on the properties of the films. As-deposited 100 nm thick ITO films exhibit a sheet resistance of $130{\Omega}/{\square}$ and optical transmittance of 77% at a wavelength length of 550 nm. By inserting a 5 nm-thick Au layer in ITO/metal/ITO (IMI) films, the sheet resistance was decreased to as low as $20{\Omega}/{\square}$ and the optical transmittance was decreased to as little as 73% at 550 nm. Post-deposition annealing of ITO/Au/ITO films led to considerably lower electrical resistivity and higher optical transparency. In the Xray diffraction pattern, as-deposited ITO films did not show any diffraction peak, whereas as-deposited ITO/ Au/ITO films have Au (222) and $In_2O_3$ (110) crystal planes. When the annealing temperature reached the 150 - $450^{\circ}C$ range, the both diffraction peak intensities increased significantly. A sheet resistance of $8{\Omega}/{\square}$ and an optical transmittance of 82% were obtained from the ITO/Au/ITO films annealed at $450^{\circ}C$.

Xiognu people were the first of the Central-Asian nomads to establish a nation in 209 B.C. They always moved around looking for places to breed their animals and fertile grounds, so they wore clothes made of fur and leather and covered their tents with felt from the livestock. This research studies on the literatures, costumes and the achievement of archaeological excavation. Furthermore, to investigate on costumes excavated of Xiongnu, we visited the Mongolian National Museum and the Hermitage Museum. A corn-hat made of felt, a felt hat with ear flaps and a golden crown with a bird on the top were unearthed from a tomb of Xiongnu in Inner mongolia. Women usually wore pigtails, and men wore pigtails or ponytails but they cut their hair short when holding a funeral. Many pigtails discovered in Noyon uul tombs can be considered as their funeral customs. The Xiongnu wore a round or v-neck caftan attached straight sleeves reaching knees in the left folded style, and because they always rode horses, having the length of the caftan not go past their buttocks would have made it more convenient for them. During the period of Western Han, Ho refered to Xiongnu and it became a common name for northern races. They used leather belts and an animal-designed buckle was found. Women commonly rouged their cheeks for a vivid and cute look, and many ornaments were excavated including bracelets, rings and decorations made of gold, silver, copper and jade, among which there were hair ornaments used to identify one's class. A horse pattern with wings and a horn of Golmod T20 was substitution for the Schythian use of deer. Patterns or shape of unearthed articles present in the Xiongnu culture in Noyon uul had a close relationship with Altaic, Greek and Persian cultures. The Xiongnu clothing was made of animals' skin and fur, woolen textiles and felt. It was folded to the left for upper garments, and the pants were adjusted using a belt and shoes were made of leather, which was very suitable for protection against the cold and horse riding. Mobility played a significant role in their clothing.

Structural differences in various divisions of the rabbit colon were investigated using light and scanning electron microscopy. For light microscopic study, various Portions of the colon from seven rabbits (2.5 kg body weight) were fixed in 10% neutral buffered formalin, and paraffin sections were stained with hematoxylin-eosin. Tissues for scanning electron microscopy were fixed in 1% glutaraldehyde-1.5% paraformaldehyde and postfixed in 1% $OsO_4$, dehydrated to 100% alcohol, transfered to isoamilacetate and dried by the critical point method. Subsequently, specimens were coated with gold and viewed with a JSM-35C scanning electron microscope. The colon displays a morphological diversity along its proximo-distal axis. Five regions can be discerned based on the macroscopic and microscopic characteristics. 1) The first segment immediately distal to the cecocolical junction possessing three teniae is approximately 5 cm ($4{\sim}6cm$) in length, and displays irregular folds of the mucosa oriented transversely similar to those of the cecum. 2) The second segment possessing three teniae is about 7 cm ($5{\sim}8cm$) in length, and is characterized by the papilla-like protrusions on the mucosal surface. 3) The third segment, possessing a single tenia is about 16 cm ($12{\sim}20cm$) in length, and also displays the papilla-like protrusions similar to the aforegoing segment. 4) Fusus coli, approximately 4 cm ($3{\sim}5cm$) in length, is free of teniae and exhibits longitudinal folds on the mucosal surface. These four portions together constitute the proximal colon. 5) The distal colon reaches a length of about 58 cm ($53{\sim}55cm$) and shows a pattern of surface irregularities with minor ridges on the mucosal folds.
