The purpose of this study is to investigate the effect of body type(thin, standard, fat), necktie width(narrow, medium, wide), gender(man, woman) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 9 color pictures manipulated with the combination of necktie-width and body type using computer simulation. The subjects were 116 male undergraduates and 99 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, young-activity, attractiveness-gracefulness, stability, and boldness. In the young-activity, attractiveness-gracefulness and stability, body type and necktie-width showed independent effect. In the boldness, body type showed independent effect. Significant interaction effects of body type and necktie-width on young-activity, attractiveness-gracefulness and stability were found. For young-activity image, necktie of narrow width were effective. For attractiveness-gracefulness image, body type of standard were effective. For stability image, body type of standard and body type of thin on necktie of narrow and medium width were effective. The male fashion image can be perceived differently according to combination of the clues used in body type and necktie-width. Therefore, when the male fashion to create images that will have to consider the body type and necktie width.

이 연구에서는 일방향 콘크리트 슬래브를 대상으로 하여, 철근을 사용한 경우와 CFRP 보강근을 사용한 경우에 대해 보강근 사용량에 따른 휨강도와 처짐 및 균열폭을 비교하여 평가하였으며, CFRP 보강근 콘크리트 슬래브의 휨설계의 지배적인 성능과 효율적인 휨설계 방안에 대해 검토하였다. CFRP 보강근을 사용한 콘크리트 슬래브는 철근을 사용한 경우에 비해 동일한 보강근량에서 더 큰 설계휨강도를 얻을 수 있는 반면, 처짐 및 균열폭은 상대적으로 훨씬 크게 발생한다. CFRP 보강근을 사용한 콘크리트 슬래브에서는 최대균열폭이 설계의 지배적인 요인으로 작용하는 것으로 확인하였으며, 효율적 휨설계를 위해서는 허용균열폭을 0.7 mm로 완화하여 적용할 필요가 있으며, 작은 직경의 보강근 적용을 검토할 필요가 있음을 제시하였다.

Optimization of geometry is one of the most important design process of the electrical motors. Tooth and yoke width are important variables that can maximize back emf and load torque among various design parameters. In this paper, in order to design the tooth and yoke width effectively, an equivalent magnetic circuit of one pole is constructed and an optimal value of tooth and yoke width resulting minimum reluctance are determined instead of a finite element analysis(FEA) that is time consuming.

The main purpose is to study the effects of princess lines on different body types and to disguise any imperfection by using diverse princess lines. We separated testers body shapes into specific body types, H, Y by applying both the direct and the indirect measurements. These designs were evaluated by using the point ranking system method, and then average scores were obtained from these evaluations. Following are the results of the study: 1 These are the resulting illusion effects when the shoulder width of the Princess line was fixed. When the Princess line originated from 1/3 point of the armhole, body types Y appeared to show narrow waist width. A-line silhouette appeared to display the narrowest shoulder width. When the Princess line originated from 2/3 point of the armhole, body types H and Y appeared to exhibit narrowest waist widths, and the A-line silhouette once again displayed the narrowest shoulder width. When the Princess line originated from 1/2 point of the armhole, body type H appeared to exhibit narrow width; and H-line silhouette displayed the narrowest shoulder width 2. When the Princess lines waist w'4th was fixed in order to study illusion effects of waist widths. In this experiment, locations of Princess lines and widths of the skirt were varied. When the waist width was fixed at 6.5 cm, For the H body type, the Princess line location of 1/3 point of the armhole in H-line silhouette design exhibited the narrowest waist width. For the Y body type in A-line silhouette design, the Princess line locations of 1/3 and 1/2 points of the armhole exhibited the narrowest waist width because it displayed the hourglass effect. When the waist width was fixed at 10 cm, H body type did not exhibit any significant differences between designs. For Y body type, A-line silhouette design with the Princess line origination point at 1/3 down the armhole exhibited the narrowest waist width. 3. The illusion effects of the hip were studied by fixating the width of the skirt and varying the locations of Princess line and waist widths. In H-line skirt silhouette designs, all two body types exhibited narrow hips when the Princess line origination points were at 1/3 and 1/2 way down the armhole. For A-line skirt silhouette, H body type exhibited narrow hips when narrow waist design with the Princess line originating from 1/2 point in the shoulder was shown. Y body type exhibited narrow hips when narrow waist design with the Princess line originating from 1/3 point of the armhole and 2/3 point of the shoulder. 4. With both waist and skirt widths fixed, all two body types exhibited taller and slender postures when the Princess line originated from the shoulder compare to the armhole.

Among these factors, attention factor is estimated by the most important factor. The visual effects by the angle and the width of shoulder line of power shoulder jacket are composed of 3 factors : whole silhouette, neck and arm figure, upper body figure. In these factors, the whole silhouette is estimated by the most important factor. The power shoulder jacket with extreme changes in shoulder angle has double images: it looks trendy and classy but also gives an awkward image. In case of changes in shoulder width, the visual evaluation shows big differences with the degree of expansion. The visual evaluation with variation in angle has stronger image and effect than that in width. The power shoulder jacket trend itself is also evaluated that variation in angle reflects the trend better than that in width.

본 논문에서는 포스트텐션 콘크리트 포장(PTCP: Post-Tensioned Concrete Pavement)과 줄눈 콘크리트 포장(JCP: Jointed Concrete Pavement)이 접속되는 터미널 조인트의 시공시 초기 줄눈 폭 설계에 대하여 연구하였다. PTCP와 JCP 사이의 줄눈 폭은 소음과 승차감에 직접 영향을 미치는 요소이다. 초기 설계 줄눈 폭이 지나치게 크면 소음과 승차감을 저하시키고, 줄눈 폭이 지나치게 작게 되면 온도 상승시 슬래브의 팽창과 블로우업 발생으로 압축응력이 과도하게 작용하여 줄눈부 파손을 야기할 수 있기 때문이다. 본 연구는 온도변화에 따른 터미널조인트의 줄눈 폭의 연구를 위하여 PTCP와 JCP가 시공된 동해고속도로 주문진현장에서 2010년 8월과 11월에 줄눈 폭 데이터를 측정하고 분석하여 최적의 줄눈 폭 설계방안을 제시하였다.

The purpose of this study is to present basic data that can express beautiful silhouette by studying visual effect that depend on waist position of basic pants and the change of round belt width and analyzing the study of visual effect of the pattern design as well as the effect of design component. The stimuli are 21 samples: 7 variations of the location of the waistline and 3 variations of the width of the belt. The data has been obtained from 35 fashion design majors. The data has analyzed by frequency, factor analysis, anova, scheffe's test and the MCA method. The visual effects by the location of waistline and the width of belt are composed of 3 factors : horizontal direction factor, vertical direction factor and flexuosity factor. In these factors, horizontal factor is estimated by most important factor. Visual effect is positive when belt width widens as the location of waist line goes down to position of low belt. And in case the location of waist line is in the position of natural waist belt and low rise belt, belt of 3.2cm width is effective visually. The interaction effects between the location of the waistline and the width of the belt have significant differences in all factors. Factor that appears in visual effect of basic pants can be evaluated differently according to pattern of pants and characteristic of body shape. So we may receive better visual assessment if we consider the location of waist belt and width of belt in side of visual effect and image, when we produce pants giving variety to crotch depth.
