Purpose: Most studies have reported that the abdominal muscle thickness differs according to gender but none of these studies reported a gender difference in the thickness of the multifidus and erector spine. The spinal alignment is affected by the left and right balance in the trunk muscle. The aim of this study was to identify the trunk muscle symmetry according to gender and the correlations of the trunk muscle thickness with spinal alignment. Methods: Forty three subjects(27 males and 16 females) were enrolled in this study. The trunk muscle thickness was measured by ultrasonography. The trunk muscle, which consisted of the rectus abdominis (RA), external oblique abdominis (EOA), internal oblique abdominis (IOA), transverse abdominis (TrA), erector spine (ES), and multifidus (MF), was measured. The spinal alignment was measured by Formetric-III 3D analysis. The dependent variables of the spinal alignment were the trunk imbalance, trunk inclination, lateral deviation, and surface rotation. Results: The muscle thickness of the EOA muscle increased more significantly in the right side than the left side (p<0.05). Each left and right difference in the muscle thickness between the male and female group showed a significant difference (p<0.05) except for the TrA thickness. Significant positive correlations were observed between the ES and lateral deviation and between the TrA with trunk imbalance. Conclusion: These results suggest that asymptomatic men have a greater trunk muscle thickness than women but there was no difference between the left and right in healthy adults. The trunk muscle thickness of ES, TrA is related by the spinal alignment.

Purpose: This study was performed to determine the position of the mental foramen relative to the apices of the teeth based on panoramic radiographs in a Moroccan population. We also analyzed gender differences and the symmetry of location within individuals. Materials and Methods: Seven hundred ninety-four panoramic radiographs were evaluated with regard to the location and symmetry of the mental foramina in male and female subjects. The results were analyzed using Pearson's ${\chi}^2$ and Fisher's exact test. Results: Of the 794 panoramic radiographs, 377 met the inclusion criteria for at least one side. The mental foramen was located just below the apex of the second premolar in 62.7% of the patients and between the first and second premolars in 30%. It was symmetrically located in 79%. No statistically significant differences were found between males and females in the position and symmetry of the mental foramen. Conclusion: The most common position for the mental foramen in this sample was in line with the second premolar.

By reviewing relatively recent theory of coercive control, which considers gender as a key concept to conceptualize domestic violence, this article explores battered women's experiences with police responses and institutional law enforcement. Using data and interviews from Korea Women's Hotline, this article analyzes the effects of state intervention which fails to support battered women and sends a message to the community that domestic violence is not such a serious crime. Specifically, this study found some problematic responses and attitudes of police and legal system: first, police is equating domestic violence with physical attacks or serious harms. Second, police and law enforcement personnel blame victims based on her gender performance or gender roles. Third, by individualizing the problem of domestic violence, state intervention ignores important structural factors that cause and perpetuate it. Finally, police and the justice system disempower and discourage battered women by exacerbating victim's fears and risks. Viewing domestic violence as a liberty crime, this study concludes that enhanced understanding of the nature of domestic violence only can contribute to solving the problem and protecting women's human rights.

Statement of problem : A scientific examination and understanding of overall aspects of the natural dentition is the first step involved in making a satisfactory selection in the shade of an aesthetic prosthesis. Proper natural shade selection of the prosthetic restoration that is in harmony with the remaining dentition is as important aesthetically, as harmony of form and function in the anterior dentition. Clinically, the most commonly applied method of shade selection has been visual, but because of the subjective nature inherent to this method, shade selection results are variable and can be influenced by such factors as the technician, the type of shade guide used, and the type and intensity of the lighting. Purpose : The purpose of this study was to develop a more objective and scientific approach to examining and understanding the shade of teeth, which has in turn lead to the development of a number of shade analysis devices that present a more objective method of shade analysis. Material and Method : In this study, the shades of healthy anterior teeth were examined and analyzed using the recently developed digital shade analysis of the $ShadeScan^{TM}$ System. The study examined 80 individuals in their twenties, 40 males and 40 females, presenting 6 healthy, unrestored maxillary anterior teeth. Tooth brushing and oral prophylaxis were performed prior to evaluation. The ShadeScan handpiece was used to acquire images of the 6 maxillary anterior teeth. These images were analyzed using the Vita/Classical mode of the $ShadeScan^{TM}$ Software, and shade maps of each tooth were acquired and divided into cervical, middle, and incisal thirds. The shade distribution of each third, left and right symmetry, and gender differences were investigated and analyzed. Results : The results of the study are as follows : 1. An overwhelming majority of the examined teeth were found to possess shades belong to Group A, with the greatest variations occurring at the middle and cervical thirds of the maxillary central and lateral incisors, in both male and female subjects. 2. Canines of both male and female subjects showed left and right symmetry with uniform shade distribution of A4 and C4, while the lateral and central incisors showed left-right symmetry of the incisal 1/3 with a uniform shade distribution of A2 and A3 shades 3. No significant differences in shade distribution were seen between genders in maxillary canines, whereas maxillary central and lateral incisors showed differences at the middle and cervical thirds between male and female subjects The results of this study show that with the exception of maxillary canines, maxillary anterior teeth display a diverse shade distribution as well as gender differences. Conclusion : Clinically, when making a shade selection using the existing shade guide, one must consider the fact that even a single tooth consists of a variety of shades. The results of this study show that when selecting a shade from a number of groups is difficult, shades from A group are the most consistent with the natural shade or maxillary anterior teeth.

Purpose: This investigation was designed to evaluate the condyle position and the symmetry of the both condyle heads at the maximum intercuspal position on the sagittal CT image of the temporomandibular joint. Materials and Methods: Cone-beam CT was used to assess 400 joints in 100 symptom and 100 symtom-free subject(100 male, 100 female). Three independent observers(dentists) determined the positions classified with Anterior Position(AP), Middle Position(MP), and Posterior Position(PP), and the symmetry of the both condyle. Results: According to gender, the mean percentages of AP, MP, and PP were 48.5, 28.5, and 23 in male group, and 34, 38, and 28 in female group. The symmetry of condylar heads was more common than asymmetry in the both of groups. In the respect of symptom or symptom-free, the mean percentages of AP, MP, and PP were 44.5, 34, and 21.5 in the symptom-free group, and 37, 33.5, and 29.5 in the symptom group. The symmetry of condylar heads was more common in the symptom-free group, but the asymmetry of condylar heads was more common in the symptom group. Conclusions: These data might serve as useful criteria for the clinical assessment of condyle position at the maximum intercuspal position optained by Cone-beam CT.

Tessellations are the pattern of iterations of geometric symmetry and translation. We can find them in the works of Escher who is the famous Dutch artist, and the American Indean life. Also, we can find the beauty of tessellations in the Korean traditional house door, Buddist temple architecture, palace's fence, etc. In the article, the figures of patterns we present are bird, fish, cat, pig, elephant, penguin, child and horse riding man, including Escher's, which are constructed using the computer geometric program, GSP (Geometer's Sketchpad). We want to talk about girl's disposition toward mathematics related to the figures. If they are supported by this kind of interesting figures constructed by their own hands, students will have more interest in learning geometric figures.

Objective: The purpose of this study was to analyze the effects of wearing spandex underwear on the muscle activity and heart rate during flexion and extension of trunk and knee joint. Background: Back pain continues to be the leading overall cause of physical illness and lowering productivity in workplace. Recently, the utility of assistive garment or back belt have been discussed to lessen the back pain as well as to preserve the right posture. Method: Ten males and ten females participated in the experiment. Gender, wearing spandex underwear and postures were used for independent variables, and muscle activity, the level of asymmetry of muscle activity and variation of heart rate were used as dependent variables. Muscle activity and heart rate were measured during flexion and extension of trunk and knee joint. Results: When wearing spandex underwear, the muscle activity was relatively low compared to the condition not wearing the spandex underwear. The symmetry of muscle activity and the variation of heart rate were statistically significant at the 0.05 significance level. In particular, it was found that the symmetry of muscle activity increased while wearing spandex underwear. Conclusion: Spandex underwear has an effect that can reduce asymmetry of right and left muscles which are relevant to leg because spandex underwear equally supports right and left low-back muscles. Application: The spandex underwear used in this study can apply to the rehabilitation as an useful assistive device.

The Korean family is changing. The growth in dual-earner households has been the 'revolution' of the century, implying inevitable modification of the role division in marriage toward greater symmetry of responsibility for breadwinning and homemaking. So, the purpose of this study is to understand husbands' housework and to investigate the change of the husbands' housework. This means to investigate how the husband is related to housework. For these research purpose, 60 dual-earner couples were deeply interviewed. The major discussions of this study can be summarized as follows: There are four types of housework in men's work, the type of refusal, the type of avoidance, the type of inevitability, and the type of participation. These types are taken order to understand change in housework is women's work. Men in the type of avoidance in household work is 25%, they have a tendency to avoid housework with making any excuses. People in the type of inevitability is 20%. These men are compelled to work in household owing to circumstances beyond control. 13% of couples is type of participation. These have a new idea of housework. They don't get the gender role division. They can become a good husband. and eventually solve conflicts and problems in couples.

The objective of the study is to understand the characteristics of modernistic spatial design and, based on the understanding, to interpret fashion in terms of its spatial relationship with society, culture and human body, thereby looking into unique spatial characteristics fashion has. The main results of this study include : First, the rational space emphasizes geometric symmetry and harmony among each of design elements and is expressed by pursuing a perfect formative beauty that indicates an eternal formal beauty of a physical space. In addition, functional beauty is also pursued, making clothing convenient for activities. Second, the abstract space is characterized as a kind of purity by emphasizing simple patterns and colors and materials of purity for clothing, and it is sometimes expressed as being extremely abstract so that human body can be shown to be distorted. Third, for the uniform and neutral space, mass-production and production at home was made possible with clothing of simple patterns and of standard. In addition, it showed a tendency to become blurred in gender distinction for clothing with women wearing men's clothing, or borrowing design elements from men's clothing. Forth, the space as means of domination and control was shown to be segmented based on place, function and purpose. In addition, control on physical beauty was shown by promoting slim figures that are suited for lineal silhouette of clothing and circumstantial restriction on clothing occurred during war, serving to limit the styles of and purchase of clothing.
