The essential oil fraction of Leonurus sibiricus was analyzed by TLC and gas chromatography. By utilizing silica gel column, a ketone compound, m.w. 167, was isolated from the essential oil. The essential oil showed considerably the diuretic action, but the water extract exhibited weak action. This diuretic action of the water extract was potentiated by combined administration of essential oil. On the isolated rabbit's uterus the essential oil decreased spontanous movement and showed relaxation.

China, more than any other countries in the world shared similar ideological system with Korea historically. That is confucian patriarchy, which later combined with socialism and capitalism respectively. Therefore, the hardship that modern chinese women had to go through in the course of great social changes would provide meaningful cross cultural insights in various women issues in Korea. Thus this study attempts to focus on Ding Ling, who is considered to be one of the first women that brought the feminism up in China. One of her early works, and from Yan'an days were analyzed to mirror current feminist movement.

This study examined the effect of calcium supplementation and exercise on bone mineral density (BMD) and general characteristics, dietary intake and biochemical measurements for 45 healthy middle-aged women (40-57 years). Subjects were divided in to 4 groups; control group (G1), exercise group (G2), calcium supplementation group (G3), and calcium supplementation with exercise group (G4). The subjects were 45.8$\pm$ 0.66 years old. BMI(kg/$m^2$) was 23.31 $\pm$ 0.63 in Gl group, 22.92 $\pm$ 0.51 in G2 group, 23.64 $\pm$ 0.61 in G3 group, 23.40 $\pm$ 0.37 in G4 group, and BMI of all groups were in normal value. Energy intake was 1332.28㎉/day, 60% of RDA, so that may be unbalance of micronutrients. Especially, calcium intake was 62.8% of RDA that was very low level. Osteocalcine was not statistically significant but calcium supplementation group (G3) be showed increase. BMD was usually decreased by Aging, but in this study was increased in the all group, except control group. It showed increase of BMD for calcium supplementation and/or exercise. Overall results indicate that calcium supplementation and/or exercise increased BMD of middle-aged women, but long-term calcium supplementation and exercise will be able to more effect.(Korean J Nutrition 35(9) : 962~969, 2002)

This study initiated research aligned with the body positivity movement, aiming to explore size diversity for groups facing relative size discrimination due to their deviation from average body types. Using KS adult women's apparel dimensions as a reference, jackets were developed for women in their 20s to 30s who belong to the small petite-size (S[P]) category, which is characterized by a height under 155cm (petite) and a bust-circumference from 72cm to less than 82cm (small). Using 3D virtual-fitting, we conducted experiment-pattern production and refinement and subsequent real-fitting evaluations by participants to objectively validate aesthetics and comfort. The study's findings are as follows: First, utilizing a 3D virtual-fitting program by identifying 'creases' and 'garment pressure points' in the jacket appearance, experiment patterns were refined and real jackets were produced. This approach addressed challenges in recruiting participants with specific body types and allowed for efficient research in terms of cost and time. Second, through real-fitting evaluations, basic-fit and slim-fit jackets labeled as <79-88-150> were developed for the S(P) size. we presented 'size spec' and 'ease allowance' for jackets by waist fit. Both fits received positive evaluations with approximately 53.5cm sleeve length, and 11.7cm shoulder length. The ease allowances for the basic-fit jacket were approximately 9.2cm at the bust circumference, 12.8cm at the waist circumference, and 6cm at the hip circumference. Similarly, the slim-fit jacket exhibited ease allowances of about 4.8cm at the bust circumference, 4cm at the waist circumference, and 4cm at the hip circumference, receiving positive evaluations for aesthetics and comfort.

The purpose of this study was to investigate the changes of various balls velocity under the different surface conditions after impact. For this study, four different balls were used which are golf ball, tang-tang ball, table tennis ball, and iron ball. And two different types of ground conditions were used which are artificial grass green and glass green. Movements of putter head and ball were recorded with 2 HD video cameras(60 Hz, 1/500s shutter speed). Small size control object($18.5cm{\times}18.5cm{\times}78.5cm$) was used in this study. To transfer the same amount of kinetic energy to the ball, pendulum putting machine was used. Analyzing the process of impact and the ball movement, a putter was digitized the whole movement but the ball was digizited within the 50cm movement. Velocities were calculated by the first central difference method(Hamill & Knutzen, 1995). Putter head velocities were about 112.2cm/s-116.2cm/s at impact. Maximum ball velocities were appeared 0.08s-0.10s after impact no matter what the ground conditions are. Table tennis ball recorded higher ball velocities than the other ball velocities and iron ball recorded the lowest ball velocity in this group. But Table tennis ball was influenced with the frictional force and immediately was decreased at the artificial grass green condition. If an object is received the kinetic energy under the static condition(v=0cm/s), the object recorded the maximum velocity shortly after the impact and then decreased the velocity because of the frictional force. The ball distance from the start position to the peak velocity position is about 6cm-10cm under the 112.2cm/s-116.2cm/s putting velocity with putter. 0.25 seconds later after impact balls were placed 40cm distance from the original position except iron ball. In this study, ball moving distances were too short therefore it was not possible to investigate the reactions after the translational force is disappeared. Rotational force would play a major role at the end of the ball movement. Future study must accept two things. One is long distance movement of ball and the other is balanced ground. Three-piece ball is a good item to investigate the golf ball movement on the different surface conditions.

The purpose of this study was to develop a caregiver's uniform that is appropriate for nursing and to improve movement adaptability as well as having a pleasing appearance. Based on the results of preliminary study, I investigated the inconvenience and problems with the existing uniforms and made a sample uniform taking into consideration the design, the material, and the pattern. We carried out a sensory assessment and quantitative assessment in order to compare the sample uniform with existing uniforms. Following are the results of this research. The top is a short-sleeved blouse with a round neckline having no collar and with armpit gussets. The armpit gussets are semicircles and the inverted pleats in the back are an improvement designed for activity. The pants are long reaching to the ankles with elastic in the waist so that the waist measurement may be adjusted. The length of the pants can be adjusted with strings and the pants have a funnel-shaped pocket for adjustment of length. We used a mix of polyurethane and polyester for the outer cloth of the uniform in order to improve activity function and used $Coolever^{TM}$, the sanitary textile that absorbs moisture well and dries in a short time, for gussets in the armpits, which is the heavy sweat area. The appearance assessment and movement adaptability assessment were performed with 5 subjects and 9 experts. For the results of the assessment, the sample uniform was appraised to be better than the existing uniforms in every item of an appearance comparison assessment except for the neckline assessment by the experts. As for the assessment of movement appropriateness and wearing assessment, the same subjects were used for analysis. As the results of the assessment, the sample uniform was rated higher than the existing uniforms in movement adaptability and pleasing appearance.

This study has carried out scanning tests in order to figure out the features of scanning search by sex of space users, with the result of which the validity of data has been estimated. In this research, the scanning patterns were set up for verifying the typology of scanning paths and then the reason for determining scanning paths and the validity of estimation method were reviewed. Since the observation features depends on sex, the analysis of visual activities for acquiring any information in a space will reveal the intention and purpose of space users. The findings by analyzing the features of scanning pattern by sex which were found at the determination of scanning patterns can be defined as the followings. First, for estimating the process of space-information search, the movement distance at each point of continuative-observation data from the angle of eye-movement has been extracted, on the ground of which the fixation and movement of eye have been defined for the establishment of scanning-cut characteristics. Second, the scanning times were estimated for the extraction of effective observation data that would be used for comparative analysis, which showed that men had more data (3,398.2/64.4%) than women (2,998.2/55.6%). This enables the acknowledgment that the scanning cut of men was relatively less, which indicates that men will acquire more information on space than women in the process of observing any space. Third, men's scanning times (58.0 times/2.02 seconds) were less than those of women (71.9 times/1.39 seconds) while the scanning time of the former was longer than that of the latter, which shows the feature that it takes longer for men than women in scanning while the scanning times of the former is less than those of the latter. Fourth, the observation features can be determined that the combination of this result with the predominance character by sex for a general viewpoint to be employed indicates that while men employ mixed-scanning for observation activities to acquire space-information spending for longer time, women, by concentrated-scanning, focus on a single point for shorter time or stay at one location for a considerably long time for space-information acquirement.

The purpose of this study was to analyze the gait characteristics and interaction between lower extremity joints according to shoe's heel heights in young women. Participants were selected as subject consisted of young and healthy women (age: $23.71{\pm}1.49yrs$, height: $165.92{\pm}2.00cm$, body weight: $54.37{\pm}3.46kg$) and walked with 3 types of shoe's high-heel (0, 5, 9 cm). The variables analyzed consisted of the displacement of Y axis in center of mass ([COM]; (position, velocity), front rear(FR) and left right(LR) angle of trunk, lower extremity joint angle (hip, knee, ankle) and asymmetric index (AI%). The displacement of Y axis in COM position showed the greater movement according to increase of shoe's heel heights, but velocity of COM showed the decrease according to increase of shoe's heel heights during gait. The hip and knee angle didn't show significant difference statistically according to increase of shoe's heel height, but left hip and knee showed more extended posture than those of right hip and knee angle. Also ankle angle didn't show significant difference statistically, but 9 cm heel showed more plantarflexion than those of 5 cm and 0 cm. The asymmetric index (AI%) showed more asymmetric 9 cm heel than those of 0 cm and 5 cm. The FR and LR angle in trunk tilting didn't show significant difference statistically according to the increase of shoe's heel height during gait in young women.

The dissolution and reconstruction of the male-centered social structure is being requested, but the Korean church still call on women and understand women's roles by limiting them based on traditional 'normal family ideology' and matherhood discourse. However, considering women's various aspects of life, life cycle, and individuality, confining women to existing biological maternal discourse is not suitable to help women grow as subjective leaders and contribute to society. The Korean church needs to find a new curriculum that encourages women to form subjective beliefs. In the life of Christian women of the period of port-opening, we can examine the process of the Korean Christian women establishing the subjectivity of the challenges of Protestant theology, which included stereotypes, gender division of labor, and matherhood discourse. Korean Christian women shared the oppressive experiences of traditional patriarchy after passing silent and receptive perceptions, forming a subjective perception of their injustice and seeking liberation. And it was able to act as a subject of faith by forming a procedural and constructive awareness within a sympathetic and relational community. The Korean church should reconstruct the Christian women's curriculum by reflecting on the curriculum that women formed themselves over 100 years ago.
