Objective: The purpose of this study was to compare walking conditions (straight line and curved path) on walking patterns in persons who had experienced hemiplegic stroke and to determine whether if they adapt their walking pattern and performances according to changes in environmental conditions. Design: Cross-sectional study. Methods: Forty-four hemiplegic stroke survivors participated in this study. This study measured walking performance in three different walking conditions, such as straight walking, the more-affected leg in the inner curve walking, and less-affected leg in the inner curve walking conditions, and a 2-dimentional gait analysis system was used as a primary measurement. This study also measured secondary clinical factors including the Timed Up-and-Go Test, the Trunk Impairment Scale, and the Dynamic Gait Index. Results: After analyzing, cadence and step length of the less-affected side, stride length in the more-affected side, and stride length in less-affected side were significantly different among the three different walking conditions in this study (p<0.05), but other temporospatial parameters were not significant. Cadence was the largest in the straight walking condition. Step length in the less-affected side, stride length in the more-affected side, and stride length in less-affected side were also the longest in the straight walking condition. Conclusions: The results of the study suggest that hemiplegic stroke survivors show walking adaptability according to changes in walking demands and conditions, and moreover, cadence and step and stride lengths were significantly different between straight and curved walking conditions.

The somatotype classification of this study was to manufacture well-fitted clothes for middle-aged women. The somatotype classification of the upper body of lateral view was based on previous studies, and 4 postures, straight posture, leaning back posture, bent forward posture, and swayback posture were selected for this study. The front of leaning back posture was longer and wider than that of straight posture, and its front neck depth was deeper. Its front interscye breadth was wider and back interscye breadth was narrower. S.N.P. B.P. front waistline length, waist front length, front diagonal length, chest shedder length, front waistline shoulder line length were longer, and S.N.P. scapular back waistline length, back length, back shoulder length, back diagonal length, shoulder line back waistline length were shorter. On the contrary, the front of bent forward posture was shorter and narrower than that of straight posture, and its back neck depth was deeper. The properties of swayback posture were similar to those of bent forward posture. Its front was shorter and narrower, but the results of front neck depth and back neck depth were like those of straight posture.

The purpose of this study was to investigate the effect of hairstyle, hair length, and hair color on women's professional image. The quasi-experimental method by a $2{\times}3{\times}3\;(hairstyle\;{\times}\;hair length\;{\times}\;hair color)$ factorial design was used. Subjects were 343 women in Seoul, Korea. The bright brown hair was perceived to be less professional than the black and the dark brown. The straight hair was evaluated to be more professional than the wavy hair in the short and the medium length hair, whereas the wavy conveyed a higher professionalism than the straight style in long hair. The shorter the hair was, the more professional the image was. Among 18 stimuli, the short straight hair in black was evaluated to have the highest in professional image, and the long straight hair in bright brown was the lowest. Perceivers in their 40's and 50's evaluated the bright brown hair to be more professional than those in their 10's to 30's did. The present findings provide that hairstyle, hair length, and hair color are significant cues when perceiving women's professional image.

Because of the congestion problems, the high-strength reinforcements are expected to be used in nuclear power plant structures in the near future. According to ACI 349-13, it is permitted to use the high-strength(550MPa) straight bars in design of development length, but there is no special equation for high-strength bars. In order to reflect the anchorage capacity and behavior properties of high-strength straight bars with large-diameter(43 & 57mm), it is necessary to find the modified factor or develop the new development length equation for large-size and high-strength bars.

PURPOSES: Recently, many local governments have applied chicanes for traffic calming to ensure environment-friendly comfortable and safe roads. However, the geometry of a chicane is designed for speed reduction using a curved portion. This study aims to improve the road geometry conditions of chicanes for reducing carbon emissions and maintaining appropriate driving speeds by considering the relationship between road geometry and carbon emissions. METHODS: This study was conducted as follows. First, carbon emissions corresponding to changing acceleration of vehicles were studied. Second, vehicle acceleration caused by the relationship between the curve radius and the straight length was studied. Accordingly, desirable conditions of curve radius and length of the straight section for reducing carbon emissions were proposed. RESULTS: The existing literature on chicanes present the minimum value of stagger length and path angle in the primary variable condition. This study suggests the maximum values of the curve radius and length of straight section in the primary variable condition. Therefore, if a vehicle's speed at a chicane is 30 km/h, this study suggests a curve radius of up to 24 m. In addition, if the vehicle's speed is 24 km/h, this study suggests a length of straight section of up to 6.6 m. These are the geometric conditions for considering the control of acceleration to the vehicle's maximum speed. CONCLUSIONS: This paper proposes an application of geometric conditions to reduce carbon emissions and maintain appropriate speeds of vehicles through a combination of curve radius and length of straight section.

The purpose of this study was to examine the effect of hair style and hair color on women's impression formation. The experimental design was $2{\times}3{\times}3$ (hair wave$\times$hair length$\times$hair color) factorial design by 3 independent variables. Subjects were 343 women in Seoul. Four factors were derived to account for the dimensions of impression formation. These were neatness, sociability, attractiveness, and femininity. The straight hairs were evaluated neater than the permed hairs, and the permed hairs were evaluated higher in sociability and attractiveness. The short hairs were perceived highest in sociability, and the long hairs were perceived high in attractiveness and femininity. The black hairs were perceived highest in neatness, the bright brown were perceived high in sociability and attractiveness, and dark brown were perceived high in femininity. Attractiveness had significant interaction effects depending on three independent variables: hair wave, lengths, and colors. Long black straight hair was perceived most attractive, and midium length black straight hair was least attractive. The light brown permed hairs were perceived high in attractiveness regardless of hair length. In the case of straight hair, the longer the hair length was, the younger the object women were perceived. The women with the long permed hair were perceived older than the women with short and midium length permed hair.

Objective: This study was performed to examine differences in the association between straight and curved walking abilities of inpatients in the subacute phase and walking independence level. Design: Cross-sectional study. Methods: Subjects were divided into an independent group and a supervised group (n=10 each) by walking independence level within the ward decided by physical therapists. Inclusion criteria comprised the ability to ambulate independently within the ward, regardless of the use of walking aids. Straight walking abilities (walking velocity, stride length, and cadence) were evaluated using the 5-meter walk test. Curved walking abilities were evaluated using the Figure-of-8 Walk Test (F8W) and the 3-meter zigzag walk test (3ZW). Differences in associations between straight and curved walking abilities of inpatients were examined by calculating correlation coefficients between straight and curved walking abilities. Results: Age, walking velocity, stride length, F8W and 3ZW varied markedly between independent and supervised groups. In the independent group, F8W and 3ZW correlated significantly with walking velocity and cadence (p<0.05). In the supervised group, F8W correlated significantly with walking velocity and stride length (p<0.05), but 3ZW did not correlate significantly with straight walking abilities. Conclusions: The association between straight and curved walking abilities varied between inpatients who could ambulate independently and inpatients requiring supervision for ambulating. These differences may depend on skill on straight and curved walking abilities. There is a possibility that curved walking exercise is necessary for supervised group.

The purpose of this study was to find out the moving fitness and slit length of tight skirt in relation to its length & silhouette. Five kinds of length, micro mini, mini, natural line, medi and maxi, and two kinds of siihuette, slim & straight-a total of ten tight skirts-were investigated. Ten college students were chosen for this experiment. The moving fitness was tested by measuring the step length, step width and step angle in the case of walking on the flat and going up the stairway & bus stair. The slit length was tested by measuring the back slit length needed in the case of going up stairway & bus stair. Data were analyzed with use of SAS pakage. The statistics were based on average, standard diviation, two-way ANOVA, Pearson's correlation and multiple regression analysis. The main results were as follows. 1. There was significant difference in the moving fitness according to length & silhouette of tight skirt. The moving fitness of slim type was lower than that of straight type and the longer the skirt length was, the lower the moving fitness was. The significance appeared particularly in the case of going up the bus stair. 2. There was significant difference in the skirt length obove slit accorting to length & silhouette of tight skirt. The skirt length obove slit of slim type was shorter than that of straight type. The longer skirt length was, the longer it was from micro mini to natural line, that of medi skirt was shorter or a little longer than that of natural line skirt and there was little change from medi skirt to maxi skirt.
