부동산 간접투자 여건을 개선하여 자금흐름의 선순환을 유도하는 것이 부동산 실물 투자 욕구를 흡수할 수 있는 효과적인 대안으로 보인다. 지난해 아파트시장에 이어 토지시장이 다시 들썩이고 있다. 정부의 각종 투기억제정책 등으로 투기가 확산되기는 힘들겠지만 시중 유동성이 자본시장 등으로 선순환되지 않는 한 부동산투기는 언제든지 재현될 가능성이 남아 있다. 부동산 투기가 상품을 바꿔가면서 반복되고 있는 가장 큰 원인으로는 저금리 기조에 따른 풍부한 유동성과 부동산 간접투자상품 등 대체투자 수단이 다양하지 못한 점을 들 수 있다. 이에 부동산 직접투자의 대안으로 부상하고 있는 부동산 간접투자 여건을 진단해 본다.

The purpose of this study is to evaluate the differences of visual effects by variations in the width of pleats and the length of the accordion pleats skirt. The stimuli are 21 samples: 7 variations of the width of pleats and 3 variations of the length of skirt. The data has been obtained from 43 fashion design majors. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: The visual effects by the number of pleats and the length of skirt are composed of 2 factors: verticality and thickness of lower body, shape of abdomen. In these factors, verticality and thickness of lower body factor is estimated by the most important factor. The accordion pleats skirt makes the lower body look longer when the width of the pleats is wider, and helps the calf and leg look thinner. Also, the waist looks more slender and thin. As the skirt gets longer, one looks taller, and legs look longer and thinner. The shape of abdomen is no difference according to the width of pleats. As the skirt gets longer, the waist looks more slender and thinner. The interaction of visual effect according to the changes in width of pleats and skirt length of accordion pleats skirt is not shown, and the skirt length has more effect than the width of pleats does in verticality and width of lower body factor. The width of pleats has more effect than the skirt length does in shape of abdomen factor.

The purpose of this study is to evaluate the differences of visual effects by variations in the number of pleats and the length of the pleats skirt. The stimuli are 18 samples: 6 variations of the number of pleats and 3 variations of the length of skirt. The data has been obtained from 54 fashion design majors. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: The visual effects by the number of pleats and the length of skirt are composed of 3 factors : vertical of lower body, curves of lower body and shape abdomen. In these factors, vertical factor is estimated by the most important factor. The visual effect is positive when the number of pleats is added and the length of skirt is getting shorter. The short length of skirt and more pleats make legs and calves looked long and slim. The interaction effects between the number of pleats and the length of skirt do not appear. In the vertical of low body factor, the length of skirt is more effective than the number of pleats, and in the curve of low body factor, the number of pleats has more effects than the length of the skirt. In the shape of abdomen, the number of pleats and length of skirt have similar influences.

The Ritz method Is applied In a three-dimensional (3-D) analysis to obtain accurate frequencies for thick. linearly tapered. annular plates. The method is formulated for annular plates haying any combination of free or fixed boundaries at both Inner and outer edges. Admissible functions for the three displacement components are chosen as trigonometric functions in the circumferential co-ordinate. and a1gebraic polynomials in the radial and thickness co-ordinates. Upper bound convergence of the non-dimensional frequencies to the exact values within at least four significant figures is demonstrated. Comparisons of results for annular plates with linearly varying thickness are made with ones obtained by others using 2-D classical thin place theory. Extensive and accurate ( four significant figures ) frequencies are presented 7or completely free. thick, linearly tapered annular plates haying ratios of average place thickness to difference between outer radius (a) and inner radius (b) radios (h$_{m}$/L) of 0.1 and 0.2 for b/L=0.2 and 0.5. All 3-D modes are included in the analyses : e.g., flexural, thickness-shear. In-plane stretching, and torsional. Because frequency data liven is exact 7o a\ulcorner least four digits. It is benchmark data against which the results from other methods (e.g.. 2-D 7hick plate theory, finite element methods. finite difference methods) and may be compared. Throughout this work, Poisson\`s ratio $\upsilon$ is fixed at 0.3 for numerical calculations.s.

The purpose of this study is to analyze the formative characteristics of accordion pleats shown in 10/11 S/S London, Paris, New York collection and evaluate the differences of visual image by variations in the width of pleats and the length of the accordion pleats skirt. The stimuli are 21 samples: 7 variations of the width of pleats and 3 variations of the length of skirt. The data has been obtained from 43 fashion design majors. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test. The results of the study are as follows: Accordion pleats was first introduced by Marriano Fortuny. He published delphos dress by creating silk pleats manufacturing technique and it was recognized as the best pleats work. Since then, pleats with synthetic fiber characteristics were used by many fashion designers. Accordion pleats were used in various items including one-peice, skirt and pants in collection of 2010 and 2011. The design of accordion pleats skirt used different width of pleats, length of the skirt and materials. The visual image by the width of pleats and the length of skirt are composed of 3 factors : dearness, attractiveness and elegance. In these factors, dearness factor is estimated by the most important factor. The accordion p1eats skirt is most attractive and dear when the width of pleats is the shortest, 1/8", and the width of 4/8" and 5/8" follows. The accordion pleats skirt is most attractive and dear when the length of skirt is similar to that of mini-skirt, and the skirt was estimated to be elegant as the skirt gets longer. When the length of skirt is in between, the skirts were estimated to be ambiguous in all visual images. The interaction effect of visual image according to the changes in width of pleats and skirt length of accordion pleats skirt was seemed to have significant differences by factors, and the main effect had great differences in all factors.

This article aims to evaluate the visual effects and images according to the changes in the width of pleats of accordion pleats skirt. I altered the width of the pleats to seven categories in changes of 0.5cm, 0.7cm, l.0cm, 1.3cm, 2.0cm, 2.5cm and 3.0cm. For the visual evaluation, seven stimuli had been placed in mannequins, and had been estimated by experts in fashion design. For the visual evaluation according to changes in the width of pleats of according pleats skirt. I used 11 pairs of items to find their visual effects, and 17 pairs of adjectives to measure the visual images. Those stimuli and adjectives had been randomly given to evaluators and had been evaluated by the seven-point Likert type scale. The data have been analyzed by frequency, factor analysis, ANOVA, Scheffes test and correlation analysis. According to factor analysis of the visual effects of the accordion pleats skirt, the result was classified into three factors: the verticality of the lower body, flexuosity of the lower body, and shape of the abdomen. According to factor analysis of the visual image of the accordion pleats skirt, the result was classified into the following three factors: activity, attraction and neatness. In visual effects, the verticality of the lower body had been assessed as the most important factor of all. The visual effect was positive when the width of pleats had been narrowed. In visual image, activity had been assessed as the most important factor. In the case of accordion pleats skirt, as the width of pleats became wider, it had a stronger image in being active and casual.

This research proposes a pattern design method for 24 pleated skirts in order to develop an automatic draft program for pleated skirts that will enhance fit and enable mass production. The research method and results are outlined as follow. 1. Three-dimensional body measurements were conducted on 30 randomly selected women in their 20s. By using 34 body measurement items and 6 types of calculations among the items, the items required in the designing of an original pleated skirt were extracted. They were then interpreted through correlation analysis, variance analysis, a t-test, linear regression analysis and multiple regression analysis. 2. An extra amount was added to the waist measurement and external capsule measurement according to the number of times the pleats coincided and the thickness of the fabric by the degree of polymerization of the horizontal cross section (the test of this research: 0.518mm). The extra amount of waist measurement was 3.6cm while the hip measurement was 4.3cm larger than the hip measurement combined with the external capsule measurement and the extra amount. 3. Based on the ${\pm}$standard deviation/2 as the average of the difference between the external capsule measurement and waist measurement, the subjects were classified into 3 somatotypes. Somatotype 1 presented an average total length of waist darts of 23.6cm while that of somatotype 2 was 26.2cm and that of somatotype 3 was 30.2cm. It has been confirmed that there is a significant difference among somatotypes in the total length of waist darts from the front center to the front side and the total length of waist darts from the side to the back center in terms of the average amount of waist darts for every 12 parts on the WL.

This study proposes a new two-level condensation scheme for the construction of a reduced system. In the first step, the candidate area is selected for the construction of the reduced system by energy estimation in element-level. In the second step, primary degrees of freedom are selected by sequential elimination from the candidate degrees of freedom linked to the selected elements. Numerical examples demonstrate that the proposed method saves the computational cost effectively and provides a reduced system which predicts the eigenvalues accurately. Moreover, the well-constructed reduced system can present the reliable behavior of the structure under arbitrary dynamic loads comparing to that of global system. Time integration in a reduced system can save the computing time remarkably. Through a few numerical examples, the efficiency and reliability of the proposed scheme are verified.
