Dressmaking which is defined as the process of changing two-dimensional cloth into three-dime-nsional clothes needs a lot of joining parts. Particularly sleeve needs a more curved surface than other joining parts owing to shape of the top of arms. Easing is used to control the fullness along the seam-line to create the fullness curved shape of the sleeves and it plays an important role in increasing three-dimensional constru-ction power. unfortunately sufficient data regarding effective easing conditions to increase three-dimensional construction power of sleeve are not available. Therefore the author tried to investigate the effective easing conditions to increase three-dimensional construction power of sleeve by cap height. Easing construction power of sleeve by cap height. Easing contraction made by different angles on the sleeve cap curve line previous work were examined and the effective easing conditions according to the variation of angles were determined. This study contains the following objectives. Firstly to obtain the easing contraction ratio in sleeve according to the above easing conditions. Secondly to investigate the three-dimensional construction power or sleeve by the factors of easing contraction. Thirdly to determine for each sleeve the effective easing conditions on the basis of the calcuative easing contraction ratio in the sleeve patterns by cap heights.

The purpose of this study is to quantitatively analyze the impacts of the distribution of easing contraction of the sleeve on the external appearance of bodice and sleeve through virtual clothing simulation. Virtual clothing is conducted by differentiating the sleeve easing in accordance with the experimental condition of bodice and sleeve that are followed by draping. And then the evaluation is carried out. As a result of an analysis of the similarity between the virtual garment and the actual clothing, the whole external appearance of the bodice and sleeve was expressed similarly. The external appearance according to the distribution of easing contraction got better as the easing contraction of sleeve was concentrated on sleeve cap in front while the appearance was better at the back as it was more gently distributed than in the front. In a comparison of armhole form, the clothing of which the top of it was most similar to S0 was S4 in which the gap between the armhole and the arm was the least and the front and rear silhouette fell relatively well. In a comparison between the position of bust circumference line and that of the sleeve base line, the front of the sleeve matched the bust circumference line as the easing contraction was distributed close to the center of the sleeve cap while in the back, the sleeve base line and the bust circumference line matched when some easing contraction ratio was added close to the armpit point. The cross section figures of garment space of the shoulder, the margin was evenly distributed in S4 or S5 with differing distributions of easing contraction in the front and the back. This study is significant in that it supplies the objective baseline data which makes a novice more able to make a good external appearance of the sleeve.

미 연준은 2015년부터 통화정책의 정상화를 진행하고 있으며, 이는 우리 경제에 상당한 영향을 미칠 수 있다. 본 연구는 '시변모수 벡터자기회귀' (Time-varying parameter vector auto regression, TVP-VAR) 모형을 바탕으로 미국 통화정책이 우리나라 금융시장과 자본유출입에 미치는 영향을 분석한다. 미국 통화정책의 변화는 신용스프레드, 페더럴펀드 금리(정책금리), 기간프리미엄 등 세 변수를 통해 파악하였다. 국내 변수로는 금융시장 지표(장기금리, 원/달러 환율, 신용스프레드)와 국제수지표 금융계정을 분석하였다. 미국 정책금리 충격은 2004~2006년 금리인상기에는 국내 금융시장에 불안을 야기 시키고 외국인 국내 투자와 내국인 해외투자의 동시 감소를 초래하였으나 2015년 이후에는 그 효과가 제한적인 것으로 드러났다. 미국 기간프리미엄의 영향력은 양적완화 (Quantitative Easing, QE) 정책 실시 이후 확대되었다. 미국 신용스프레드가 국내 금융시장과 자본유출입에 미친 충격은 글로벌 금융위기 이후 크게 확대된 것으로 나타났다. 미국 통화정책 정상화의 파급효과 예측을 위한 시뮬레이션을 실시한 결과 정책금리 인상 자체보다 이로 인해 금융시장이 불안해질 때 발생할 수 있는 신용스프레드의 상승이 국내 금융시장에 더 큰 부작용을 미치는 것으로 나타났다. 자금유출입 측면에서 미국 통화정책 정상화는 외국인 투자자금의 국외이탈 압력 증가로 이어지나, 내국인의 해외투자자금이 국내로 환수되면서 이를 상쇄한다.

This study compared and analyzed current sleeve head products for men and women to develop sleeve head products for aesthetically-designed sleeves. Men and women's sleeve head products, suitable for sleeve caps, were designed and developed based on the results. The study results are as follows. First, men and women's sleeve heads for aesthetic jacket sleeves were designed with sleeve patterns in the background. Sleeve heads and upper sleeves were additionally designed to make 7-layers for men and 4-layers for women. Second, sleeve head patterns were designed so that men's would have a whole length of 48cm, an angle of $30^{\circ}$ and a width of 4.5-7.5cm; in addition, women's would be 40cm, $30^{\circ}$ and 4-5cm. Third, the same materials were used for men's and women's sleeve head products, and the background was made from 1-layer of soft non-woven fabric. As for the sleeve heads, 2-layers and 1-layer of non-fusible interlinings were used for men's and women's, respectively. In order to provide flexibility, the materials were designed in a bias direction. For upper sleeves, 1-layer of non-woven fabric and felt were used for men's, and 1-layer of felt for women's so that an empty space caused by easing contraction can be supplemented.
