Objectives : The authors performed this study to further understand Saam acupuncture treatment in an aspect of the use of two patterns i.e. fixed- and transformed-pattern. Methods : The authors did documentary survey based on Do Hae Kyo Kam Sa Am Do In Chim Beop. 1. We investigated the frequency of the use of fixed- and transformed-pattern as well as the examples of use. 2. We surveyed related literatures and classified transformed-pattern. We did study on the principles of prescriptions of fixed- and transformed-pattern and researched the utilization. Results and Conclusions : 1. Fixed-pattern occupys 35.3% and transformed-pattern takes much more part. 2. Fixed-pattern is based on Nangyoung 69nan, and has the prescription of two enhancement and two inhibition by adaptation of Sangsaengsanggeuk(相生相剋) into self meridian and other meridian, and suggests the importance of the order of needling. 3. There are main points and assistant points in tonifying and suppressing of Fixed-pattern, accordingly, it has a system like Gunshinjwasa(君臣佐使). 4. Transformed-pattern is classified into following 3 types: first, the use of Nangyoung 75nan; second, the substitution of Junghuyl(井穴) with Hyunghyul(滎穴) or Haphyul(合穴) according to Nangyoung 73nan; third, the substitution of the same Osuhyul(五輸穴) in other meridians.

The stator winding faults diagnosis technique based on MCSA is as follows. Firstly, collecting the 3 phase motor currents, that signal is transformed by (d-q transform, $i_d$, $i_q$). Park's vector pattern, the circle that is down by d-q transformed currents($i_d$, $i_q$). The circle is widely used for stator winding faults detection. The current distortion ratio(DR), defined by the ratio of max-axis and min-axis of ellipse of Park's vector's pattern. In this study, distortion ratio of Park's vector pattern is suggested for Auto diagnosis of stator winding short fault and usefulness of distortion ratio is verified through simulation using LabVIEW program.

디지털 워터마킹은 이미지, 사운드와 같은 멀티미디어 데이터에 지각할 수 없도록 비밀 정보를 삽입하는 기법이다 일반적으로 주파수 영역 워터마킹 기법에서는 원 이미지에 대해 주파수 변환을 하고, 그 변환 면에 부호화된 워터마크 데이터를 삽입한다. 본 논문에서 우리는 Fresnel 변환을 이용한 새로운 컬러 이미지 워터마킹 기법을 제안한다. 워터마크 이미지를 Fresnel 변환시켜 얻은 패턴의 값들을 컬러 이미지에 삽입한다. 본 워터마킹 모델은, 컬러 이미지에 대한 워터마크 삽입을 위해 원 이미지를 RGB 성분에서 YCrCb 성분으로 분해를 한 후 Y 성분에 워터마크 이미지의 Fresnel 변환된 패턴의 실수와 허수 값을 삽입하는 기법이다. 제안된 기법의 유효성을 검증하기 위한 워터마크 삽입 추출 실험 결과 유효성을 입증 할 PSNR 값을 나타냈으며, 또한 JPEG와 같은 손실 압축 공격에 대해 내성을 지니고 있음을 보였다.

This paper presents a watermarking algorithm for embedding visually recognizable pattern (Mark, Logo, Symbol, stamping or signature) into the image. first, the color image(RGB model)is transformed in YCbCr model and then the Y component is transformed into 3-level wavelet transform. Next, the values are assembled with pattern watermark. PN(pseudo noise) code at spread spectrum communication method and mutilevel watermark weights. This values are inserted into discrete wavelet domain. In our scheme, new calculating method is designed to calculate wavelet transform with integer value in considering the quantization error. and we used the color conversion with fixed-point arithmetic to be easy to make the hardware hereafter. Also, we made the new solution using mutilevel threshold to robust to common signal distortions and malicious attack, and to enhance quality of image in considering the human visual system. the experimental results showed that the proposed watermarking algorithm was superior to other similar water marking algorithm. We showed what it was robust to common signal processing and geometric transform such as brightness. contrast, filtering. scaling. JPEG lossy compression and geometric deformation.

본 논문에서는 MSA에 전기력선을 제한 받지 않도록 용량을 장하한 변형된 MSA와 S자형 변형된 MSA를 제안하였다. 설계ㆍ제작된 S자형 변형된 MSA는 2.24GHz의 중심주파수에서 5.75%의 대역폭을 갖고, 임의의 급전점 변화에 따라 대역폭과 공진주파수의 변화를 보였다. 또한 S자형 변형된 MSA의 측정된 방사패턴에서 E-면과 H-면을 비교 분석하였다.

This study looked into the trend of expression of animal motifs that appears in modern fashion, and the values embedded in them. As to the research method, empirical analysis was performed on the works presented at the four global collections of Paris, Milan, New York and London from 2001S/S to 2010F/W, as well as a literature review. As a result, animal motifs applied in modern fashion appeared in material groups, such as leather or feather. The first group shows a realistic material feel, with artificial leather or fur, expressed in a transformed complex animal motif, with process skill or various methods of expression. The second group is the case of a single motif or reality, mode, and ion pattern. Printing is a generic expression, but patchwork, collage or bead ornament are also used, and expressed in the various forms of pattern: pattern in a single animal, pattern in different animals, and pattern combining both animal and other shape. The third group is a small decorative ornament, including headset or accessory and makeup, which is transformed in an animal-characterized motif into part of clothing components for expression, or to set the real animal to the stage for a performance. The embedded values were also categorized as natural beauty, sensual female beauty, pleasure, and ornamentation, which could be an endless spiritual source, and a breakthrough that enables us to show a creative and new aesthetic for the modern fashion field.

광학적 Hough 변환 필터 배열을 이용하여 입력영상의 특징을 추출할 수 있는 방법을 제안한다. 여기서는 입력 영상의 부분들이 대용되는 필터 배열의 요소들에 의해 독립적으로 동시에 Hough 변환된다. 하나의 광학적 Hough 변환 필터를 사용하여 입력영상 전체에 대한 변환 결과를 얻는 기존의 방식에 비해, 제안한 방법은 입력 영상에 존재하는 선소 특징의 대략적 위치 정보를 함께 얻을 수 있고 복잡한 입력영상에 대해서도 광학적 정확성을 높일수 있다. 이 방식을 실험적으로 입증하기 위해 $5\times5$ Hough 변환 필터 배열을 제작하고 기초적인 실험을 수행하였다.

본 실험은 형질전환 담배내에서의 배유 특이 promoter에 의한 gus 유전자의 조직 특이적 발현 여부와 전이유전자의 후대로의 유전 양상을 확인하고자 수행하였다. 배유 특이 promoter에 의해 유도되는 gus 유전자(Z4pro-gus)와 kanamycin 저항성유전자를 운반하는 BV3 construct를 A. tumerfaciens을 이용하여 담배 형질전환체를 유기시켰다. 형질전환체 중에서 8개체를 선발하여 nptII primer를 이용하여 PCR을 실시한 결과 8개체 모두에서 700bp의 PCR 산물을 얻을 수 있었다. Promoter에 따른 유전자의 발현양상을 알아보기 위하여 Z4pro-gus가 전이된 형질전환체의 잎과 CaMV35S와 gus 유전자(35Spro-gus)로 구성된 pBI121 construct를 전이시킨 형질전환체의 잎으로부터의 발색정도를 비교하였다. 그 결과 Z4pro-gus가 전이된 형질전환체의 경우 잎에서 매우 부분적으로 극소량 발색되었으나 35Spro-gus가 전이된 형질전환체의 잎에서는 상대적으로 많은 양의 발색정도를 보여 promoter에 따른 발현정도의 차이를 보였다. 보다 명확한 Z4 promoter의 조직 특이 발현 양상을 확인하기 위하여 Z4pro-gus로 형질전환시킨 $T_0$ 식물체를 자가수분하여 얻은 $R_1$ 종자와 35Spro-gus를 형질전환시켜 같은 방법으로 얻은 $R_1$ 종자를 histochemical assay하였다. 그 결과 35Spro-gus로 형질전환된 담배 종자는 절단면 전체에서 gus 유전자가 발현되어 배유뿐만 아니라 종자 내 다른 조직에서도 발색되는 양상을 나타내었으나 Z4pro-gus를 형질전환 시켜 얻은 종자의 경우는 배유 부분만이 조직 특이적으로 파랗게 발색되었고 배 또는 그 이외의 조직에서는 gus 발색이 전혀 관찰되지 않았다. Kanamycin 저항성검정을 실시한 결과 모든 계통에서 전이유전자가 후대로 안정적으로 전이됨을 확인할 수 있었다.

The continuous chip generated in cutting process deteriorates workpiece, tool, and machine tool system. It is necessary to treat this continuous chip in ductile material machining condition for stable cutting. This paper deals with the chip control method using acoustic emission(AE) signal in pure copper turning operation. AE raw signals, root mean square(RMS) signals and wavelet transformed signals measured in turning process are introduced to analysis for chip patterns. With analysis of AE signals, it is obtained that the produced chip patterns are correlated with the specified AE signals which are transformed by fuzzy pattern algorithm. By this experimental investigation, the chip patterns can be classified at significant level in pure copper machining process and controlled from continuous chips to reduced-length stable chips.

The hairy root was induced form potato tuber disc by infection of a. rhizogenes. The detection of the agropine and mannopine by paper electrophoresis confirmed that induced hairy root was transformed by A. rhizogenes. The activity of peroxidase was the highest at 5 weeks and isozyme pattern of peroxidase revealed 3 cathodic bands and 2 anodic bands and new C4 band(pI 4.6) was observed at 7 weeks after cultivation in hairy root was isoelectric focusing. To study the effect of Ca2+ on cell wall formation in hairy root, channel blocker of Ca2+ was treated. The activity of $\beta$-glucan synthetase II(GS II) related to cell wall synthesis was inhibited by about 50% in diltiazem and flunarizine treatment than that of control, but stimulated in CaCl2 treatment. Therefore these results showed that Ca2+ might be an effective factor in the cell wall formation. The activity of GS II by NaF treatment was increased by about 30%. This result suggested that the activity GS II is changed through phosphorylation process.
