IIn the United States, professional dress codes for working women have changed over time since the 1970s. Considering the changes, from conservative and traditional business uniforms in the 1970s, business casual in the late 1980s through 1990s, and the current revival of tailored business suits, this study investigated working women's business jacket practices and their association with personal, psycho-social, and physical characteristics. Working women's job satisfaction and corporate culture were also examined in relation to business jacket practices. Research data were collected by implementing mail surveys to 1,500 randomly selected working women in the United States. Of the 1,500 distributed questionnaires, a total of 312 were returned, of which 265 were deemed usable, yielding a 20.8% response rate. For data analysis, descriptive statistics, such as frequency, percentage distribution, mean scores, standard deviations, and Canonical Correlation were tabulated. The respondents ranged in age from 22 to 65. The mean age of the respondents was 44 years(SD=9.63). Most respondents were married(77.4%), working full-time(81.4%), career-oriented (77.2%), Caucasian(89.8%), had at least one child(78.9%), and had a professional job(75.9%). Working women's age, number of children, self-confidence in dressing, perceived importance of clothing, body frame size, and visibility to superiors and public were positively associated with business jacket practices, while age of first child, family size, dress size, and job satisfaction were negatively associated with business jacket practices.

This article investigates the interrelationships in daily returns using fractionally integrated error correction term and volatilities using constant conditional correlation and dynamic conditional correlation GARCH with asymmetries between Capesize and Panamax markets. Our findings are as follows. First, for the fractionally cointegrated error correction model, there is a unidirectional relationship in returns from the Panamax market to the Capesize market, but a bidirectional causal relationship prevails for the traditional error correction models. Second, the coefficients for the error correction term are all statistically significant. Of particular interest are the signs of the estimates for the error correction term, which are all negative for the Capesize return equation and all positive for the Panamax return. Third, there are bidirectional volatility spillovers between both markets and the direction of the information flow seems to be stronger from Panamax to Capesize. Fourth, the coefficients for the asymmetric term are all significantly positive in the Capesize market, but the Panamax market does not have a significant effect. However, the coefficients for the asymmetric term are all significant, implying that the leverage effect does exist in the Capesize and Panamax markets.

The object of this study lies on classifying the size, which is mostly favored in Korea where the wedding dress is usually regarded as an article for rent, and on suggesting the range of sleeve design and that of neck line of bodice. For that, I extracted the average size by analyzing and researching the standard size of actual bodice from real wedding dress manufacturing company. According to the result of the research I named the standard size of Korean wedding dress for rent as 'WM' which has the girth of 88cm and the waist measure of 69cm. Based on the size 'WM', I also named the size 'WS' which has the girth of 82cm with extra length of 6cm up and down and the waist measure of 64cm with extra length of 5cm, and the size 'WL' which has the girth of 94cm and the waist measure of 74cm with same extra length as the size 'WS'. The extra space for the inseam of the back is 3 inches for left and right for all sizes and the mark of body size is standardized as 'girth-waist measure'. After that, I suggested the design types of sleeves and neck line of bodice which defined as its size by classifying the bodice of wedding dress based on its size. Generally the neck line of the tank top style has the widest range of wearable size, and the high neck line and bateau neck line types have the narrowest range. And the sleeveless type has the widest range of wearable size while the raglan type has the narrowest one.

In recent times, the median filtering (MF) detector as a forensic tool for the recovery of forgery images' processing history has concerned broad interest. For the classification of MF image, MF detector should be designed with smaller feature set and higher detection ratio. This paper presents a novel method for the detection of MF in altered images. It is transformed from BMP to several kinds of MF image by the median window size. The difference distribution values are computed according to the window sizes and then the values construct the feature set same as the MF window size. For the MF detector, the feature set transformed to the model specification which is computed using latent growth modeling (LGM). Through experiments, the test image is classified by the discriminant into two classes: the true positive (TP) and the false negative (FN). It confirms that the proposed algorithm is to be outstanding performance when the minimum distance average is 0.119 in the confusion of TP and FN for the effectivity of classification.

HEVC is the latest joint video coding standard with ITU-T SG16 WP and ISO/IEC JTC1/SC29/WG11. Its coding efficiency is about two times compared to H.264 high profile. Intra prediction has 35 directional modes including dc and planer. However an accurate mode decision on lots of modes with SSE is too costly to implement it with hardware. The key idea of this paper is a DCT shared architecture to reduce the complexity of HEVC intra encoder. It is to use same DCT block to quantize as well as to calculate SSE in RDO. The proposed intra encoder uses two step mode decision to lighten complexity with simplified RDO blocks and shares the transform resources. Its BD-rate increase is negligible at 20% on hardware aspect and the operating clock frequency is 300MHz@60fps on FHD ($1920{\times}1080$) image.

본 연구에서는 brush painting공법을 이용하여 인쇄형 유기태양전지에 적용이 가능한 ITO nanoparticle/Ag nanowire/ITO nanoparticle (Nano IAI) 다층 하이브리드 투명 전극의 전기적, 광학적, 구조적 특성을 연구하였다. 평균 25 nm 사이즈의 ITO 나노 입자로 구성된 ITO 나노 잉크와 직경 20~25 nm의 Ag nanowire 잉크를 기반으로 Brush painting 기술을 적용해 상온, 상압에서 낮은 면저항과 높은 투과도를 가지는 Nano IAI 하이브리드 투명 전극을 제작하였다. Nano IAI 투명 전극 제작 시 일정한 두께에서 Ag nanowire 코팅을 위한 brush painting 횟수를 변수로 하여 최적화 공정을 진행하였으며, Ag nanowire가 2번 brush painting 된 Nano IAI 다층 하이브리드 투명전극은 $3.4{\times}10^{-3}$ ohm-cm의 비저항과 52.33 ohm/square의 낮은 면저항을 나타내었다. 이를 통해 효과적으로Ag nanowire를 ITO nanoparticle 사이에 삽입할 경우, 고온의 열처리 공정을 통하지 않고 낮은 면저항을 가지는 인쇄형 투명 전극을 구현할 수 있음을 확인할 수 있었다. 특히 Nano IAI 다층 하이브리드 전극은 83.83%의 높은 투과도를 나타내는데 이는 삽입된 Ag Nanowire의 폭과 길이가 나노 사이즈이기 때문에 입사되는 빛이 흡수되기보다 대부분 투과하기 때문으로 사료된다. 또한, XRD 분석과 HRTEM 분석을 통해 Nano IAI 다층 하이브리드 투명전극의 전도 메커니즘을 설명하였다. 이와 같은 우수한 전기적, 광학적 특성은 brush painting 기법으로 제작된 Nano IAI 다층 하이브리드 투명 전극의 인쇄형 유기태양전지 적용 가능성을 나타낸다.

In this paper, we proposed a method for measuring accurate positions and sizes of package and balls in a micro BGA. To find defects of BGA accurately, we focused on finding positions of package and balls. After labeling, we detected connected components of package and balls using feature parameters. After the detection of package component, we measured position and size of package by employing rectangular model which was constructed by the package information. After the detection of the ball components, we measured positions and diameters of balls by employing circular models which were constructed by the ball informations. We did calibration based on landmarks to measure real length, and we compared the measured results with the SEM data. Finally, we found that the accuracy of the proposed method is 94% in terms of ball's radius.

The mobile communication service is widely used and the repeaters is rapidly increasing because of the extending service areas. we propose a new Signed CMA(: Constant Modulus Algorithm) algorithm for ICS(: Interference Cancellation System) as a larger service area of mobile communication service. The proposed Signed CMA algorithm improved performances by adjusting step size values. We showed that the proposed algorithm could improve the Mean Square Error(: MSE) performance of Signed CMA. MATLAB(: Matrix Laboratory) is employed to analyze the proposed algorithm and to compare it with the experimental results. At the convergence of 1000 iteration state, the MSE(: Mean Square Error) performance of the proposed Signed CMA algorithm with step size of 0.0065 is about 5 dB better than the conventional CMA algorithm.
