최근 시계열 데이터베이스 기반의 다양한 응용 분야에서 서브시퀀스 매칭(subsequence matching)연구가 활발히 진행되고 있다. FRM과 DualMatch은 효과적인 서브시퀀스 매칭을 위해 처음 제안된 해결책이다. 이후 이들을 일반화한 GeneralMatch가 제안되었으며, 최근에는 GeneralMatch의 이원적 접근법인 DualGMatch가 제안되었다. 본 논문에서는 GeneralMatch와 DualGMath를 비교 분석 하고자 한다. 이를 위해, 먼저 윈도우 구성 관점에서 GeneralMatch와 DualGMatch를 평가한다. 다음으로, 두 해결책을 최대 윈도우 크기 효과와 인덱스 저장 효율 관점에서 이론적으로 비교 분석한다. 마지막으로, 실제 시계열 데이터를 활용하여 GeneralMatch와 DualGMatch의 인덱스 페이지 접근 횟수를 비교한다. 분석 결과, GeneralMatch가 윈도우 크기 효과와 인덱스 저장 효율 측면에서 DualGMatch보다 우수한 것으로 나타났다.

This paper proposes penalty factor equations that take into consideration the weld strength over-match given in the classified form similar to the revised equations presented in the Code Case N-779 via cyclic elastic-plastic finite element analysis. It was found that the $K_e$ analysis data reflecting elastic follow-up can be consolidated by normalizing the primary-plus-secondary stress intensity ranges excluding the nonlinear thermal stress intensity component, $S_n$ to over-match degree of yield strength, $M_F$. For the effect of over-match on $K_n{\times}K_{\nu}$, dispersion of the $K_n{\times}K_{\nu}$ analysis data can be sharply reduced by dividing total stress intensity range, excluding local thermal stresses, $S_{p-lt}$ by $M_F$. Finally, the proposed equations were applied to the weld between the safe end and the piping of a pressurizer surge nozzle in pressurized water reactors in order to calculate a cumulative usage factor. The cumulative usage factor was then compared with those derived by the previous $K_e$ factor equations. The result shows that application of the proposed equations can significantly reduce conservatism of fatigue assessment using the previous $K_e$ factor equations.

Mix & Match Visual Image, appearing in T-shirt one-point graphics, is a new visual image emerged as a result of several trends: development of cutting-edge machinery and computer programs, various needs of consumers, and an international trend of fusion concept. Thus, a concrete research of Mix & Match Visual Images is demanding. This paper studies one-point graphic, which appeared in the SamsungDesignNet, Interfashion Planning, and firstviewkorea, with a focus on apparel T-shirt of women's wear and casual wear from 2001 to 2004. The study shows that the most preferred independent visual image in Mix & Match Visual Images is a typography, and next is in the order of marks, symbols, geometric diagrams and abstract shapes, animals and plants, characters, materials, and collages. As Mix & Match of independent visual images was mainly combined typography with other independent visual images, we need to develop more Mix & Match Visual Images using various independent visual images's mix and match. Then, T-shirt will be one of the most representative items in Korean fashion trend that enable consumers to express their characters, escaping from the old-fashioned concept that T-shirt is just a T-shirt.

본 논문은 대학 졸업생의 숙련 불일치 문제에 대한 분석의 일환으로 임금으로 대표되는 노동시장성과에 대해 전공-직업 일치의 시각에서 접근한 것이다. 실증 분석에 있어서는 선행연구들에서 자주 제기되었던 표본선택편의 문제를 명시적으로 분석 과정에 반영하였고, 분석의 편의상 이항변수로 취급되었던 전공직업일치 변수도 설문조사가 제공한 다항선택변수로 설정하여 분석하였다. 특히 1982년, 1992년, 2002년 세 코호트에 대한 조사 결과를 활용하여 비교적 장기간에 걸친 노동시장의 구조적 변화도 고려하고자 하였다. 실증분석 결과, 전공일치 직업선택에 따른 표본선택편의와 전공직업일치의 임금효과를 확인할 수 있었다. 또 전공직업일치 정도와 비례해 임금프리미엄도 체증하고, 특히 전공계열별 분석을 통해 사회 계열, 공학 계열, 자연 계열에서 전공과 직업이 일치한 경우 상대적으로 높은 임금을 확인할 수 있었다. 그러나 전공 계열별로 선택편의의 영향에 차이가 있음도 볼 수 있었다. 또 1982년, 1992년, 2002년을 비교하면 1992년에 전공직업일치 경향은 급격히 낮아졌고 1992년과 2002년의 차이는 오히려 크지 않아 이 같은 숙련 불일치 현상이 상당히 오래 전부터 진행되어 온 현상임을 확인할 수 있었다.

The past Romanticism, which emphasized loveful, womanish property, has changed into new-concept Romanticism as it was harmonized with various emotional cultures and trends in the 21st century. New-concept romanticism is found in various fields ranging from personality, diversity and discrimination to emotion. It is appearing as a new style searching for taste as it is mixed and matched with other fields. In fashion, Romanticism and mix-and-match trend provide womanish feeling through the match with romantic chiffon, high-waisted pants and cashmere cardigan and show modern emotion through vest and short blazer. Therefore, it is necessary to reconsider the method to analyze and express fashion emotion style on the basis of mix-and-match trend of Romanticism. The purpose of this study is to analyze how Romanticism is expressed in the mix and match with other emotional style, predict direction of Romanticism style and establish the ground to find changing fashion trend accurately. The researcher expects that design development will be focused on the fashion, which is more various and characteristic and search for convenient, healthy life, on the basis of the analysis on mix and match shown in Romanticism fashion of the study. The researcher tried to provide the base of design development and assist design activation by using mix and match, which can create various new styles, accurately and understanding and predicting the fashion trend of the 21st century.

In this work, the effect of strength mismatch on plastic limit loads is quantified for similar metal weld plates with cracks under tension load, via three-dimensional, small strain elastic-perfectly plastic finite element analyses. Relevant variables related to plate geometry and crack length are systematically varied, in addition to the weld width. An important finding is that mis-match limit loads can be uniquely quantified through strength mis-match ratio and one geometry-related parameter. Based on the proposed limit load solutions, reference stress based J-integral estimates is also investigated. When the reference stress is defined by the mis-match limit load, predicted J-integral values agree overall well with FE results.

Purpose - The purpose of this study is to investigate the effect of model attractiveness on brand attitude and purchase intention, and examine whether product-model match-up plays a moderating role in the relationship between model attractiveness and brand attitude and purchase intention. The model attractiveness is consist of psychological and physical attractiveness of the model. The authors investigate how product-model match-up influence the strength of the relationship between model attractiveness - brand attitude and purchase intention. The purpose of this is to test whether product-model match-up influence the form and effectiveness of a model attractiveness on brand attitude and purchase intention and suggest the effective and efficient methods in the model selection strategies to increase advertising effectiveness based on the results of this study. Research design, data, and methodology - The experimental design for this study was the between subject design based on 2 group of the psychological attractiveness(high vs. low) × product-model match-up(high vs low) and 2 group of the physical attractiveness(high vs. low) × product-model match-up(high vs low). And a preliminary investigation was conducted to develop experimental stimuli through manipulation check to enhance the external validity of experimental research. The attractiveness of the model and product-model match-up are independent variables and manipulative variables in presentation of experimental stimuli. The self-administered methode experiment was conducted on 300 subjects in four groups constructed according to the independent variables. Result - The findings provide partial support for a moderator for product-model match-up on the model attractiveness - brand attitude and purchase intention. First, the influence of psychological attractiveness and physical attractiveness on brand attitude and purchase intention was shown significant. Also, it was found that the average value of brand attitude and purchase intention according to psychological attractiveness was significantly higher than the average value of brand attitude and purchase intention according to physical attractiveness in additional analysis. Second, the average value of brand attitude and purchase intention were higher when product - model match-up was high in both high and low psychological attractiveness and physical attractiveness of the model. However, in the case of psychological attractiveness, the correlation effect with product - model match-up was significant, but in the case of physical attractiveness, it was not significant. Conclusions - The results of this study suggest that the attractiveness factor should be considered in selecting the ad model by verifying the effect of the attractiveness of the model on the advertising effect. In particular, this study has great significance both academically and practically in terms of suggesting such implications that the advertising effect of psychological attractiveness and physical attractiveness may be different depending on the product type by additional analysis.

The oscillation character of permanent magnetic motor is highly related to its slot-pole match. By calculating air-gap magnet field and radial electromagnetic force of 6-phase fractional-slot concentrated-winding permanent magnetic motor with slot-pole match of 48/44, 48/46, 48/50 and 48/52 under no load and load status, oscillation character of permanent magnetic motor is analyzed. A 20kW prototype with 48 slots and 44 poles is designed. With many sensors attaching to the corresponding parts, oscillatory acceleration is measured, and spectrum of oscillation frequency is recorded as well. The experiment results give proof to the analysis method for permanent magnetic motor oscillation in this paper.
