This study was carried out in order to find out the pattern of the root resorption following maxillary incisor retraction after maxillary 1st bicuspid extration in maxillary protrusion patients. For this study, thirty two patient who received orthodontic treatment were chosen. The results were as follows; 1. Of the total 192 teeth, 61 teeth(31.77%) showed no apical root loss, 64 teeth(33.33%) fell into the class "slight", 46 teeth(23.96%) fell into the class "moderate". Only 21 teeth(10.94%) were classified as "excessive". 2. No correlation was noted between the amount of apical root loss and the types of tooth movement of the maxillary central incisors. 3. The patients who were treated with standard brackets had more changes in tooth axis and less movement of root apexes, but the patients with straight brackets had less changes in tooth axis and more movement of root apexes. 4. Comparing the degree of root resorption between bracket types, patients who had used standard brackets showed more apical root loss than patients who had used straight brackets. 5. The most frequent degree of root resorption observed in standard bracket patients was second degree, followed by first degree and third degree. The most frequent degree of root resorption observed in straight bracket patients was zero degree, followed by first, second degree and third degree.
When we design a dress, we should not only consider the esthetic sense and the relationship between movements of the body and the type of dress, but also the combination between the qualities and proper uses of textiles. recently the sale of ready-made clothes has been booming but I wonder whether they have been made in accordance with research concerning body movements and dresses. I would like to make the following observations on dresses, because I have personally suffered the inconvenience of restricted arm movements when wearing ready-made clothes. I have made four types types of foundations with muslin and Jersey, with these foundations I measured the degree of tension or how much the waist-line was drawn up then the arm was moved in increments of 45 degree angles and there by covering the entire span of vertical and horizontal movements. I have intended to experiment with sleeves of differing height in several ways. Concerning the movement factor, I have determined that with excessive activity vertical movements are twice as uncomfortable as horizontal movements. Concerning the faburic, I have found that because jersey has more elastic qualities than muslin, it has proven to be more responsive to body movements. concerning dresses, I have fund that the higher the height of the sleeves, the more uncomfortable it is to move the arms and the greater the degree to which the waist-line is drawn up. As a result this experiment I have made the following observations. Firstly, the vertical movement of the arms to a 180 degree angle has the most extreme influence on the breadth of movement of the waist-line. Secondly, because jersey permits freer body movements than muslin, it should be the preferred material for use in making sportswear. Thirdly, the formula A·H/4+3 of the sleev's cap height is suitable for making street dresses and formal wear. The formula A·H/5 and A·H/6 are properly used when making working clothes and sportswear, and the formula A·H/8 is proper for a sleeping garment and clothes for patients. Fourthly when deciding to any garments, it is important to consider the amount of arm movement anticipated and the relationship between the material and the degree to which the waistline is drawn up. In nder-blouse, when we raise our arms to the most extreme position, we should at that point still have 20∼25 cm of material remaining under the waist-line which includes the maximum of 14.1cm plus part of the blouse and breath of skirt's belt. In the case of the over blouse it is proper for us to have the length of 17∼20 cm remaining below the waist-line.

This study aimed to identify the asymmetry observed in the electromyography (EMG) activity patterns of selected trunk and thigh muscles between the affected and unaffected sides during the sit-to-stand movement in ambulatory patients with post-stroke hemiparesis. This study included 20 patients with post-stroke hemiparesis. The differences between stroke fast walkers (${\geq}8m/s$, 11 subjects) and stroke slow walkers (<8 m/s, 9 subjects) were compared. The activation magnitude and onset time of the multifidus, lumbar erector spinae, hamstrings, and quadriceps during the sit-to-stand movement were recorded through surface EMG. Moreover, the EMG activation magnitude and onset time ratios of each bilateral corresponding muscle from the trunk and leg were measured by dividing the relevant values of the unaffected side by those of the affected side. In all the subjects, the activation magnitudes of the multifidus, hamstring, and quadriceps on the affected side significantly decreased compared to those on the unaffected side (p<.05). The onset time of muscle activity in the affected side was markedly delayed for the multifidus and quadriceps during the task (p<.05). The activation magnitude ratios of the quadriceps were markedly decreased in the stroke slow walkers as compared to those in the stroke fast walkers. These findings indicate that the asymmetry in the multifidus, hamstring, and quadriceps muscle activation patterns in patients with post-stroke hemiparesis may be due to the excessive muscle activation in the unaffected side to compensate for the weakened muscle activity in the affected side. Our findings may provide researchers and clinicians with information that can be useful in rehabilitation therapy.
This study was inquire into the state of the family ethics during the period of the beginning of 1880′s to the 3.1 independence movement of 1919 which has been the black period in the history of Korean family ethics. The research was conducted by analyzing the newspapers, magazines, related literature and articles of the period. It was the beginning of the 1860′s and by the "Cheondo-Kyo" (the Religion of the Heavenly) way that the issues regarding the equality of sexes as the central concern of the modem family ethics came to be the object of the social discourse for the first time in Korean history. The social discourse had come to be positively activated around 1900, when the intellectuals of the "Korean enlightenment" had begun to the feel necessity of the modernization of Korean socialite and the importance of the women education as the essential part of it. However, the activation of the social discourse itself, especially with the newspapers of that period did not mean the changes of the traditional Confucian family ethics, but the discourse of the modernizing forces had become the seeds for changing the family ethics of the Korean people. The made chauvinistic nature of the family ethics of the period was not so much different from those of the preceeding patriarch societies, but the state of the family ethics during the period are characterized by several social phenomenon such as the rising needs of using the "Hangle"(Korean alphabet) instead of Chinese character for the equal education of the both sexes, increasing practices of the early marriage, customs of trade marriage in accordance with the demand of excessive weeding presents, and regarding social consciousness of the traditional family ethics as patriotics attitude against the Christian rejection of the ancestor worship ritual.
This study was designed to examine the kinematic factors in the phase during the marche fente motion. For this study, the subjects were 5 elite male fencing players. The direct linear transformation (DLT) method was used in calculating 3-D coordinate of the digitized body parts. The cubic spline function was used for smoothing and the kinematic data for displacement, velocity, angle variables were calculated for Kwon3d ver 2.1. And the following conclusions were drawn; 1. It show that the marche phase appeared to longer time than the pante phase In the performance time. For the fast attack, it showed that the subjects should be moving in a short stride width. 2. For a fast and stable movement posture in the marche phase, the vertical change of COG must be maintain the same position as possible, but all subjects appeared to decrease the COG because of a excessive the knee flection. 3. In the COG velocity change, all the subjects showed to the same change in both the marche and the fente phase. However in the attack extremity velocity, it increased velocity in order of upper arm, fore arm, and hand in the marche phase, but it showed different velocity among each subjects at the moment of stabbing. So that in order to do effective stabbing, they have to extend their upper extremity max and do faster the distal segment than the proximal segment. 4. It showed to take a fast and stable movement, because some subjects showed the big anteroposterior angle of the trunk flexed max shoulder angle and elbow angle of their attack arm and the other upper extremity.
The purpose of this study was to evaluate the kinematic effect of upper extremity usage for the scoccer instep kick motion. Ten male university students were recruited as the subjects. Temporal parameters, ball velocity, velocity of CG, angle of segment, angular velocity, and trunk orientation angle were determined for each trial. The results showed that temporal parameters in WU and WORU were significantly less than those found in WOU during pre impact phase. These indicated that no usage of upper extremity may increase excessive setup time in order to improve the accuracy of instep kick. Angle of right knee in WOU at LC was significantly greater than corresponding value for WU since angular momentum contributions of the lower limb were not effectively balanced by contributions of the upper limb. We found that the lower extremity movement was controlled by lateral movement in the trunk as a result of no usage of the upper extremity, resulting in the relatively greater trunk rotation in WOU.
Observation about space is looked steady in an instant, but in continuous movement, one's observation unconsciously stays at different points. In department store, customer actually observes around the store for buying, not focusing on certain point. By studying customer's movement and observation feature, buying desire and interest can be found. For analysis of the different searching-features according to the continuous-observation depending on sex, the study is set up to record movements of customers at women in Department store. The following are the findings. First, Men observed 0.2-0.4 units more in I-II section which are assumed as predominant. The result shows that men can focus on more section (around +0.4%) and longer (around +5.7%) than women do. Second, the same feature of observation depending on sex is that both men and women observe left and right section while keep focusing on middle section. Third, according to the fact that right-focused observation magnificently occurred in the image curved to right, the Space-composition has influenced on the observation of both men and women on the space. Forth, excessive number of display can cause avoidance of observation. Moreover, observation does not stay on the coverage due to wall or post, but is attracted to the brand name. As brand name causes right-focused observation in the image [(8)], brand name can be one of the reasons to attract observation in women apparel store. To sum up, this study is noticeable as it researches about continuous-observation. Furthermore, verifying the result that the composition of space and the placement of products can cause big differences in the observation feature is meaningful outcome.

Background Excessive bleeding is one of the most severe complications of orthognathic surgery (OGS). This study investigated the associations of intraoperative blood loss and surgical time with the direction of maxillary movement. Methods This retrospective study involved patients who underwent OGS from October 2017 to February 2020. They were classified based on whether maxillary setback was performed into groups A1 and B1, respectively. Relative blood loss (RBL, %) was used as an indicator to compare intraoperative blood loss between the two groups. The surgical time of the two groups was also measured. Subsequently, the patients were reclassified based on whether posterior impaction of the maxilla was performed into groups A2 and B2, respectively. RBL and surgical time were measured in the two groups. Simple linear and multiple regression analyses were performed. P-values <0.05 were considered to indicate statistical significance. Results Eighteen patients were included. The RBL and surgical time for the groups were: A1, 13.15%±5.99% and 194.37±42.04 minutes; B1, 12.41%±1.89% and 196.50±46.07 minutes; A2, 13.94%±3.82% and 201.00±39.70 minutes; and B2, 9.61%±3.27% and 188.84±38.63 minutes, respectively. Only RBL showed a statistically significant difference between the two groups (A2 and B2, P=0.04). Conclusions Unlike maxillary setback, posterior impaction of the maxilla showed a significant association with RBL during surgery. When performing posterior impaction of the maxilla, clinicians need to pay particular attention to surgery and postoperative care.
This paper is intended to explore femininity, the ideal beauty of body and the features in fashion pursued in the fashion system and the Anti-Fashion Movement in the Victorian period, on which the modern fashion is based. For the informative facts needed in this paper, books on history, fashion history, feminism, art history of aestheticism and tole ideal beauty of body are referred to. On the part I of this paper, the femininity and the ideal beauty of body implied in the fashion system in the Victorian period will be reviewed. following are the conclusion : First, in the Victorian period, the value of femininity is put on the body of female by the discrimination of sex divided in two. Consequently, the characteristics of femininity mainly include dependence, passiveness, emotion, beauty, maternity, innocence, and purity. To emphasize the function of reproduction as primary duty and nature of female, the ideal beauty of body is represented in the form of Venus Naturalis, which symbolizes the fertility. And the external form of this body is expressed in slum waist line, ample busom and hip in fashion. Second, the features of this fashion are classified into three categories by their internal value : images of subordinate female, sensual female and maternal female 1) The image of subordinate female is expressed by concealment of legs, tightening the upper part of the body in corset and restriction on action by the crinoline 2) The image of sensual female is revealed in brazing colors and decoration, excessive exposure of the upper part of the body and hip by means of bustle. 3) The image of maternity is expressed in swollen skirt of crinoline, oval bustle silhouette metaphoring the extended womb resulted from pregnancy.

In Cheon Won Gi Dae Ron(天元紀大論), Cheon(大) means Nature, Won(元) means sources, Gi(紀) is Gang Gi(綱紀) that means rules or regulations, so Cheon Won Gi(天元紀) means sources and rules of change that make Nature phenomenons. This volume treats of cause that weather change of Nature caused by, and its general rules, and presents fundamental notions and systems of measuring of 'Five elements' evolutions and Six kinds of natural factors(五運六氣)'. So named Cheon Won Gi Dae Ron(天元紀大論). This article of the research on the Cheon Won Gi Dae Ron(天元紀大論) can be divided into 3 chapters. Chapter 1 presents a theory that the principle of changes of creations' birth, groth and extinction is complished by sympathizing with Hyeong(形) of Ji(地) and Gi(氣) of Cheon(大) by rules of movement of O Un Yum Yang(五運陰陽). Chapter 2 presents theories that Tae Heo(太虛) makes Won Gi(元氣), and this Won Gi(元氣) makes the change of creations' birth, groth and extinction, and movement of O Un(五運) controls creation of nature. And treats of that 'excessive and short(太過不及)' that is made by a quality of Gi(氣) and ups and dons of Hyeong(形) controls weather of year. In Chapter 3, Cheon O Ji Yuk(天五地六) regard six and five as Yong(用). And A Cycle that movment that sympathizing with O Un(五運) and Yuk Gi(六氣) is Il Gi(一氣) as 30 years, and Il Ju(一周) as 60 years. And presents that O Un(五運) and Yuk Gi(六氣) that Gan Ji(干支) control.
