The purpose of this study was to investigate gather as decoration techniques of clothes. In this study, we defined 21st century as the modern fashion. And analyzed design that applied gather concerned with Milan, New York, London, Paris, Tokyo Woman's Collections. Data were used from Fashion News and Gap Press Magazine (2001-2004). The results of this study were as follows: 1. Gather was the most original techniques among decoration techniques of clothes and formed three-dimensional space. 2. There were many kinds of gather such as cluster gather, all gather, shirring, smoking, frill, flounce, ruffle. and it gave a different impression with Fabrics, cutting method, sewing method, parts that were used. 3. Gather had practical functions providing enough space in activity and was presented as new shape by three-dimension body motion when it was put on. 4. After analyzing design that applied gather showed in collections, there were various appearance according to designer's sensitivity.

Recently much attention has been paid for interference mitigation technique for the COMA system, since more capacity is available with same bandwidth. In this paper, we introduces a novel adaptive interference suppression techniques for the CDMA system with narrow band interference. The proposed interference rejection scheme employs the adaptive linear prediction techniques in the subband. In each subband, we can more easily find and cancel the narrow band signal as compared to the full band. Thus, the proposed interference rejection can be classified as another time-frequency techniques for the narrow band interference rejection(10). Computer simulation is conducted for the 3-G COMA system with IF band sampling techniques, yielding better interference rejection and bit error rate performance as compared to conventional one. Also, optimum filter is analyzed and from the analysis, it can be shown the subband prediction techniques can suppress narrow band interference more efficiently.

There has been considerable recent interest in deep learning techniques for structural analysis and design. However, despite newer algorithms and more precise methods have been developed in the field of computer science, the recent effective deep learning techniques have not been applied to the damage detection topics. In this study, we have explored the structural damage detection method of truss structures using the state-of-the-art deep learning techniques. The deep neural networks are used to train knowledge of the patterns in the response of the undamaged and the damaged structures. A 31-bar planar truss are considered to show the capabilities of the deep learning techniques for identifying the single or multiple-structural damage. The frequency responses and the elasticity moduli of individual elements are used as input and output datasets, respectively. In all considered cases, the neural network can assess damage conditions with very good accuracy.

Objectives: This study was designed to introduce distinctive Do-In techniques among the many found in the book 'Euibangyoochi'. Methods: 'Do-In section' of Euibangyoochi was translated, and distinctive Do-In techniques were extracted from it. These techniques were categorized as 'using specific actions', 'using vocal sounds'. Results: The Do-In methods in the 'Do-In section' of Euibangyoochi were categorized. The first category includes Do-In methods that involve specific actions, such as 'Myung Chun Go', 'Go-chi Beob', 'Ak-go Beob', 'Gun-yok Beob', and 'An-ma Beob'. The second category is the Do-In technique using vocal sounds, known as 'Yuk Ja Gyeol'. Conclusion: The 'Do-In section' of Euibangyoochi contains numerous Do-In techniques recorded in various texts. Among them, techniques with specified names were extracted and categorized. While there are currently no studies on the actual effects of these techniques, it is hoped that future research can validate their efficacy.

Background and Purpose : The purpose of this study was done to investigate what kinds of statistical techniques have been used to analyze data from oriental medicine research Methods : 135 original articles which used statistical techniques in their data analysis were selected from the articles published in The Journal of Korea Institute of Oriental Medicine(JKIOM) between 1995 to 2007. Results : Among 135 articles, 59 articles used descriptive statistics while 76 articles used inferential statistics for data analysis. For that 76 articles, two-sample t-test(33 articles), analysis of variance(29 articles), regression(9 articles), chi-square test(5 articles), nonparametic test(4 articles), Fisher's exact test(3 articles), and other test(9 articles) were chosen to analyze the data. SAS and SPSS statistical softwares(82.50%) were mostly used to analyze the data. Nonparametic tests were used to 4 articles(6.97%) of 67 articles and parametic tests were used to 63 articles(93.03%) of 67 articles. Among 29 articles used analysis of variance, duncan(8 articles), dunnet(4 articles), bonferroni(4 articles), turkey(3 articles), scheff(1 article) were used to do multiple comparison. 9 articles did not carry out the multiple comparison. Conclusions : It was found that the frequencies of statistical package used and statistical analysis used were not much by now. High level statistical analyses were not used most for oriental medicine research.

소프트웨어의 규모가 커지고 복잡해지면서 소프트웨어의 기능적 실패(Functional Failure)를 만들어 내는 위험(Hazard) 요소들을 분석하기가 어려워지고 있다. 안전 필수 시스템(원자력 발전소, 항공관제 시스템, 철도 운영 시스템)에서 이런 기능적 실패는 곧 큰 사고 (인명피해, 환경오염) 로 이어지게 된다. 따라서 이러한 기능적 실패를 방지하고 소프트웨어의 안전성을 높이기 위해서는 소프트웨어 안전성 분석이 필요하다. 하지만 몇 가지 이유 (시간과 노력, 안전성 분석 기법의 다양한 지식 부족, 기관이나 회사의 관습적인 방법 사용) 로 적절하지 못한 안전성 분석 기법을 선택하게 되는 경우가 있다. 따라서 본 논문에서는 기존 안전성 분석 기법과 최신 안전성 분석 기법, 통합 모델 몇 가지를 소개 하겠다. 이것을 통해 전문가는 여러 종류의 안전성 기법을 간략하게 확인 할 수 있을 것이고, 시스템에 맞는 안전성 분석 기법을 선택하는데 도움을 받을 수 있을 것이다.

흙의 변형을 측정하기 위해 적용되는 이미지 해석 기법으로는 Particle Image Velocimetry(PIV)와 Digital Image Correlation(DIC)가 있으며, 이 기법들이 더욱 널리 활용되기 위해서는 각 기법에 따라 다양한 조건에서 정밀도를 평가하는 연구가 필요하다. 본 연구에서는 이미지 해상도, 변위 및 변형 정도, 픽셀 집합의 크기 및 해석 기법의 다양한 요소를 고려하여 사질토의 변형을 관찰하기에 적합한 최적의 이미지 해석 기법을 제시하고자 한다. 개별요소법(DEM)을 이용하여 구성된 가상의 사질토 이미지를 활용하여 이미지 해석을 행하고 변위를 산정한 후, 개별 요소법의 변위와 비교하였다. 각 영향 요소들이 정확도에 미치는 영향을 분석하였고, 변위 및 변형 정도에 따라 최적의 이미지 해석조건을 제시할 수 있었다.

The volatile component analysis of 82 commercialized liquors(44 samples of single malt whisky, 20 samples of blended whisky and 18 samples of brandy) was carried out by gas chromatography after liquid-liquid extraction with dichloromethane. Pattern recognition techniques such as principle component analysis(PCA), cluster analysis(CA), linear discriminant analysis(LDA) and partial least square discriminant analysis(PLSDA) were applied for the discrimination of different liquor categories. Classification rules were validated by considering sensitivity and specificity of each class. Both techniques, LDA and PLSDA, gave 100% sensitivity and specificity for all of the categories. These results suggested that the common characteristics and identities as typification of whiskies and brandys was founded by using multivariate data analysis method.

While conventional business administration-based information technology management methods are applied to the risk analysis of information systems, no security risk analysis techniques have been used in relation to information protection. In particular, given the rapid diffusion of information systems and the demand for information protection, it is vital to develop security risk analysis techniques. Therefore, this paper will suggest an ideal risk analysis process for information systems. To prove the usefulness of this security risk analysis process, this paper will show the results of managed, physical and technical security risk analysis that are derived from investigating and analyzing the conventional information protection items of an information system.

The technology of gait analysis is moving rapidly. Human gait is very complex, and a through understanding of it demands with the basic principles of biomechanics and the technology used to measure gait. Some professionals reluctance to use gait analysis may be due to the amount of time and effort necessary to accomplish this and the necessity for teamwork among the disciplines involved. Any form of observational gait analysis has limited precision and is more descriptive than quantative. The techniques of 3-D kinetic and kinematic analysis can provide a detailed biomechanical description of normal and pathological gait. This article review gait characteristics and procedures that are available for gait analysis. We are certain that, given the steady advance of technology and our continued efforts to document the benefits of that technology. gait analysis will soon be a routine part of the evaluation of both the elite athlete and the physically impaired adult or child.
