  • The purpose of this study is to evaluate the differences of visual image on variations in the length and princess line, in a silhouette of a one-piece dress with the application of the 3D Virtual Clothing System known as i-designer. Eight sample were examined: 2 variations of the length and 2 variations of the princess line, 2 variations of the form of a silhouette. The data was obtained from 66 fashion design majors. The data was assessed by a t-test and a multi-way ANOVA and factor analysis. The results were as follows; The visual image according to the design variables, four factors were selected; the attractiveness factor, the activeness factor, the practicality factor, the elegance factor. In these factors, the attractiveness factor is estimated by the most important factor. As a result of analyzing the effect of the interaction in the visual image according to the design variables, the influence of the main effect was found to be great in each factor. In the activeness factor, a significant difference was noted in the two-way interaction between the length and the princess line, the length and the silhouette. In the elegance factor, a significant difference was noted in the two-way interaction between the length and the silhouette. However, the influence on three-way interaction among the length, the princess line, and the silhouette was not significant.

  • Stability of high-speed roll-to-roll printing machines is one of the most important factors that are required for the printing machines to operate properly and to obtain reasonable printing performance. This paper proposes a new model for the web-tension system of a high-speed gravure printing machine considering span-length variations due to dancer rollers, and analyzes the stability of plant dynamics of the printing machine using the proposed model. Span-length variations due to dancer motions are considered for the modeling of plant dynamics in two ways; one is to include the effect of span-length variations without considering dancer inertias and viscous frictions, and the other is to include the effect of span-length variations with considering dancer inertias and viscous frictions. The stability of the plant model is analyzed for various web-speeds using the eigenvalues of the linearized model about operating points.

  • The purpose of this study is to evaluate the differences of visual effects by variations in the shoulder length and puff volume of the puff sleeve blouse. The stimuli are 21 samples: 3 variations of the shoulder length and 7 variations of the puff volume. The data has been obtained from 40 fashion design majors. The data has analyzed by Frequency, Factor Analysis, ANOVA, Scheffe's test and MCA method. The result of the study are as follows. The visual effects by the shoulder length and puff volume are composed of 4 factors : the width of the upper body, the shape of the breast part, the shape of the neck part and the shape of the upper arm. In these factors, the width of the upper body is estimated by most important factor. In view of the visual effects by variation of the shoulder length, the shorter shoulder length goes, the more positive visual image comes in the shape of the breast part. In comparison of the differences of visual effects by the 7 variations of puff volume, the arm looks thin and long when the puff volume goes enough and the breast part has a better visual assesment in case the puff volume goes poor. In the interaction effects between the shoulder length and puff volume, the shoulder length have significant differences in the shape of the breast part, the shape of the neck part and the shape of the upper arm and puff volume has significant difference in the width of the upper body.

  • The purpose of this study is to evaluate the differences of visual image by variations in the volume of flare and the length of flare skirt. The stimuli are 12 samples: 4 variations of volume of flare and 3 variations of the length of skirt. The data has been obtained from 181 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 image by the volume of flare and the length of flare skirt are composed of 4 factors : matureness, attractiveness, stiffness and softness, moderateness. In these factors, matureness is estimated by the most important factor. When the volume of flare is $180^{\circ}$, the visual images are shown to be better. As the skirt gets shorter, it has more vivid and attractive image. And as the skirt gets longer, it looks older and gentle but not too plain or ordinary. The volume of flare and skirt length interact with each other in matureness and attractiveness factors. But the volume of flare affects more in stiffness and softness and moderateness factors than skirt length.

  • The purpose of this study is to evaluate the differences of visual image on variations in the shoulder strap and length of the monokini swimsuit. Nine samples were examined: 3 variations of the shoulder strap and 3 variations of the swimsuit length. Data have been obtained from 90 fashion design majors and analyzed using Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: 1) The visual image, according to changes in the shoulder strap and length of monokini swimsuit, was composed of boldness factor, attention factor and attraction factor. Boldness was the most important factor in the monokini swimsuit. 2) The visual images according to changes in the shoulder strap of the monokini swimsuit are ranked in the order of one shoulder strap, strapless and two shoulder straps. They are shown to be untidy - a trendy image, showy -a characterful image and wanted to dress -an unnatural image. 3) As the swimsuit gets shorter, it has more untidy - trendy image. As the swimsuit gets longer, it looks more tidy and classic. 4) The number of shoulder straps and swimsuit length do not interact with each other in boldness factor, attention factor or attraction factor. However, the number of shoulder straps affects more than swimsuit length in the visual images of the monokini swimsuit.

  • Because of its embryonic origin, the thyroid gland is predisposed to multiple anatomical variations and developmental anomalies. These include the pyramidal lobe, the origin of levator glandular thyroidae, the absence of the isthmus, ectopic thyroid, accessory thyroid tissues, etc. These anatomical variations are clinically significant to surgeons, anatomists, and researchers. The present study was designed to report anatomical variations and developmental anomalies of the thyroid gland in Ethiopian population. The study was conducted on 40 cadavers used for routine dissection classes. The thyroid gland was exposed and observed for any variations and developmental anomalies. The length, width, and thickness of the lobes were measured using a vernier caliper. Differences in the incidence of pyramidal lobe and absence of the isthmus between sexes were tested using a Pearson chi-square test. The mean length, width, and thickness of the right lobe were 4.24 cm, 1.8 cm, and 1.6 cm, respectively, whereas it was 4.08 cm, 1.8 cm, and 1.6 cm, respectively for that of the left lobe. The pyramidal lobe was noted in 52.5% of the cadavers. The levator glandulae thyroidae were prevalent in 40% of the cadavers. The isthmus mainly overlies the 2nd to 4th tracheal rings and was absent in 7.5% of the cadavers. Accessory thyroid tissue and double pyramidal lobes were noted in 2.5% of the cadavers. Most of the variations of the thyroid gland were seen frequently in female but it was not statically significant. Different clinically important and rare variations of the thyroid gland were found.

  • 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.

  • This study examined the radial variations in element demensions of mongolian oak (Quercus mongolica.), elm (Ulmus japonica.), maackia(Maackia amurensis.), castor aralia (Kalopanax pictus.) from pith outwards. Disks were cut from the d.b.h.(above 1.2m) of each species and specimen for tangential pore diameters, fiber length, ray height and width were taken from 1-3rd, 5th, 10th, 15th.............40th ring number from pith. The tangential pore diameters in the earlywood increased rapidly near the pith and then maintained almost constant or very gradually increased diameters in about 20th-30th ring number from pith. In the latewood, tangential pore diameters gradually increased from pith to outwards though the increment is smaller than in early wood. Radial variations of ray height and width maintained almost constant, gradually increased or rapidly increased diameters and then maintained almost constant from pith to outwards. Patterns of radial variations in the fiber length were almost coincident with patterns of earlywood pore diameters, and of ray height or width in Ulmus japonica and Maackia amurensis.

  • Circadian rhythms have been observed to be disturbed in mood disorders, especially seasonal affective disorder (SAD). Clock related gene variants also have been suggested to be associated with seasonality (seasonal variations in mood and behavior). This study tested the potential association between a length polymorphism of Period3 gene and seasonal variations in mood and behavior. 297 Korean college students were genotyped for the Period3 polymorphism and were for evaluated the seasonal variation by Seasonal Pattern Assessment Questionnaire (SPAQ). The genotype frequencies were 0.76 for 4R/4R, 0.22 for 4R/5R and 0.013 for 5R/5R. The global seasonality score was not different among Period3 gene variants (4R/4R, 4R/5R and 5R/5R) except for 'sleep length' subscore. The 5R/5R genotype showed the higher 'sleep length' subscore than others (p=0.024). The comparison between seasonals (syndromal plus subsyndromal SAD determined by SPAQ) and non-seasonals did not show any significant difference in frequencies of genotypes. These findings suggest that there is a possibility that the investigated Period3 polymorphism may play a partial role in the susceptibility of seasonal variations in a Korean population.
