Purpose : This study identifies the effect of ankle-taping on limb asymmetry, postural sway and lumbar flexibility. Ankle-taping was applied for participants of this study and the results were compared to the control group. Methods : This study targets 46 adults, in which 25 composed the test group and 21 composed the control group. All participants were interviewed. For the test group, inflexible tapes of 5mm width were applied as designed by Danaka Nobudaka while the tapes for the control group were arranged in a symmetric direction to the direction of the test group. Postural balance was measured using Mediance (Human Tech Inc, Korea) and to identify lumbar flexibility, the trunk flexion is targeted. Results : 1. The postural inclination of both the groups decreased, but a statistically significant difference is not found (p>0.05). 2. Both the groups increased, but no statistically significant difference is found (p>0.05). 3. Both the groups increased, and a statistically significant change is found (p<0.05). Conclusion : As demonstrated in the results above, ankle taping is effective for lumbar flexibility as well as stability of ankle joints regardless of the direction of taping. It also suggests that ankle taping is helpful for health management of athletes and the public. However, as the results are limited in that they were obtained 10 minutes after taping, it is hoped that further studies will follow.

안면비대칭의 주원인은 하악골이며, 하악골의 비대칭 성장에 대한 상악골의 보상성장에 따라 교합면 경사 등이 초래된다. 디지털 사진과 삼차원 CT 등 다양한 방법으로 정확한 진단을 하고 수술을 포함한 치료계획을 세운다. 술전 교정 치료는 상악골과 하악골 치열의 치성 보상(dental compensation)을 제거하면서 상악 치열의 중심은 상악골의 정중선에, 하악 치열의 중심은 하악골 정중선에 맞게 이동하여 술후 상하악 치열궁이 일치하면서 동시에 안모 정중선에 일치하게 맞추어야 한다. 악교정 수술은 일반적으로 상하악 동시 수술을 하게 되며 우각부 풍융도 교정과 이부 성형술(genioplasty) 등을 부가적으로 할 수 있으며, 교합면 경사 교정과 수평 회전 등의 이동이 상하악 위치에 서로 영향을 주면서 수술 후 안모 변화에 대한 예측을 어렵게 만들기 때문에, 다양한 분석을 통해 정확한 예측으로 최선의 결과를 얻는 것이 가장 중요하다.

Landslides generally occur due to influences of the internal and external factors. Internal factors include ground characteristics, terrain and so on. External factors can also be divided into natural factors such as rainfall, ground water, earthquake and so on, and artificial factors resulting from cutting and embankments. Among these factors, rainfall becomes the most important external factors by means of which landslides occur in Korea. To appropriately deal with tile effects of pore water pressures due to rainfall, the method using the pore water pressure ratio(r$\_$u/) is generally applied in slope stability analysis or the design of slope reinforcements. Since tire value of r,, is in general not constant over the whole cross section, in most slope stability analyses the average values are used with little loss in accuracy. However, determination of the average values of r$\_$u/ to applied in the design is difficult problem. Therefore, in this study, tile average values of r$\_$u/ according to the intensity of rainfall and slope inclination is suggested based on results of the small scaled model tests using the artificial rainfall apparatus. It is found from the model tests that the average values of r$\_$u/ is about 0.07∼0.18(in case of the intensity of rainfall is 50mm/hr.), about 0.10∼0.28(in case of the intensity of rainfall is 100mm/hr.), and about 0.10∼0.33(in case of the intensity of rainfall is 150mm/hr.).

The experimental evidence evaluation of the 11th grade students(N:91) was investigated. Specially, the influence of students' ideas about optical phenomena and presented evidence types on their evidence evaluation, and the influence of students' ideas on their causal inference modes were investigated. After eliciting the students' ideas about shadow phenomena and conformity of their idea, the experimental results with a binary outcome were presented as the evidence. Then the students were asked to evaluate the evidence. Again students' ideas were elicited. Most of students had causal ideas such that the shape of object(96%) and the inclination of screen(75%) were causes of shadow shape, not the shape(70%) and color(92%) of light source. In the case of the shape of object and the color of light source, most students(70%) believed strongly their ideas. Most responses(80%) in the evidence were evidence-based, and 12% of them were theory-based. There was no significant difference of reponses types between students with causal ideas(81%) and students with non-causal ideas(78%), between covariable and non-covariable evidence. But in the case of non-causal ideas, covariable evidence was more likely to yield evidence-based reponses than non-covariable evidence. If students had preconcepts inconsistent(84%) with the evidence, they were more likely to make evidence-based responses than the students with consistent ideas (75%) with the evidence. Especially in the case perceptually biased evidence, this tendency was marked. In the case of covariable evidence, many students made inclusion inferences(40%) rather than uncertainty inferences(32%). In the case of uncertainty inferences(94%), students more likely to make evidence-based reponses than inclusion inferences(83%) and exclusion infernces(88%). In the case of inclusion inferences and exclusion infernces, students tended to make idea-based responses and distort the evidences. In conclusion, when the students evaluate the experimental evidences, their ideas influence the causal inference modes. Especially, according to the conformity of the preconcepts and logical relation of evidences, the inference modes are more strongly depended upon the preconcepts rather than evidences.

얕은 토층의 무한사면 파괴가 예상되는 지역에서 안전율 계산에 영향을 주는 지역적 특징인 뿌리점착력을 고려하지 않은 무한사면 안전율은 뿌리점착력을 적용한 무한사면 안전율 보다 낮은 수치로 해석되는 경향이 있다. 따라서 합리적인 무한사면의 안전율을 계산하기 위하여 지역적 특징을 반영한 안전율 해석이 필요하다. 본 연구에서는 수목의 뿌리와 수관밀도가 무한사면의 안전율에 미치는 영향을 분석하기 위하여 기존 무한사면 안정해석 방법에 수관밀도를 고려한 뿌리 점착력 이론을 적용하여 안전율의 변화를 비교 분석하였다. 해석결과 뿌리점착력의 효과로 인하여 안전율이 증가하지만, 사면의 경사에 따라서 안전율의 증가량이 다른 것으로 분석 되었으며, 뿌리점착력의 보강 효과는 완만한 경사의 사면일수록 커지는 것으로 나타났다.

The purpose of this study was to illuminate eroticism represented din modern fashion. Art based on sex is very important like all of the other cultural values. But we feel that erotic art, neglected, suppressed , and persecuted for centuries, has an important contribution to make to the understanding of art, the social history of mankind, and human happiness and progress. It is our deep personal conviction that erotic art serves important social and therapeutic functions. Erotic art expresses the demand for sexual freedom-a freedom vital to individual happiness and mental well-being, And sexual freedom, in turn, cannot exist without a high degree of political and economic freedom as well. In that sense , erotic art came a truly revolutionaly message ; it demands no less than extension of freedom , not only in the sexual are, but in every sphere of social life. What is eroticism \ulcorner Eroticism must be distinguished from a mere animal reproduction . Eroticism is deeply rooted in the cultural tradition of myth, religion , customes and art. It also has a close relationship with psychological activities of our life. Eroticism is a kind of psychological revolution in the development of human civilization. Eroticism is related to different kinds of art, which express internal spirit of human especially Surrealism. Surrealism is above all a movement of the conquest and deepening of the unconscious. The exploitation of Freud's discoveries opended a new, practically unlimited path for artistic studies to Surrealism . Especially all theory of mental psychoanalysis a affected artists greatly in western art, Freud was appraised highly on his achievements by art critics in art history on his achievements by art critics in art history. As far as erotic subject matter was concerned, Surrealism provided a means of presentig it. Pop Art is not actually a movement , born at a specific time and place, nor is it an easy concept to define. The term first appeared in Great Britain during the fifties, when it referred, particularly in the decorative arts, to an inclination to go back and imitate the stereotyped images of the mass media : film, advertising , cartoons, and other popular consumer products. The eroticism expressed in Pop Art calls the modern's attentions to their devastated minds, taking advantage of the commercialized sex. Fashion has developed constantly reflecting the spiritual aspiration and social and cultural phenomona of man , and artistic steam. Eroticism in fashion is the style which expresses the internal meanings of sexuality through the texture, color, pattern , silhouette etc.

This study have goal with conceptual design for Offshore Structures of high pressure control valve for localization. Ball valve for development accomplished with flow analysis based on provision of ANSI B16.34, ANSI B16.10, ANSI B16.25 In order to localize the Offshore Structures high pressure control valve. Numerical simulation using CFD (Computational Fluid Dynamic) in order to predict a mass flow rate and a flow coefficient form flow dynamic point of view. The working fluid assumed the glycerin (C3H8O3). The valve inlet and outlet setup a pressure boundary condition. The outlet pressure was fixed by atmospheric pressure and calculated until increasing 1bar to 10bar. CFD analysis used STAR-CCM+ which is commercial code and Governing equations were calculated by moving mesh which is rotated 90 degrees when ball valve operated opening and closing in 1 degree interval. The result shows change of mass flow rate according to opening and closing angle of valve, Flow decrease observed open valve that equal percentage flow paten which is general inclination of ball valve. Relation with flow and flow coefficient can not be proportional according to inlet pressure when compare with mass flow rate. Because flow coefficient have influence in flow and pressure difference. Namely, flow can be change even if it has same Cv value. The structural analysis used ANSYS which is a commercial code. Stress analysis result of internal pressure in valve showed lower than yield strength. This is expect to need more detail design and verification for stem and seat structure.

This study was alone to identify the meaning and the essence of the menopause experience by means of the Colaizzi’s phenomenological method. The participants were eight women, 48-60 years old, who were experiencing perimenopause or postmenopause. They were selected using a theoretical sampling technique. Data were collected through in-depth interviews from April 6 to May 20, 1999. The interviews took from 40 to 90 minutes. Interviews were tape- recorded and analyzed using the constant comparative method. Significant statements from data were extracted. From these formulated meanings, 18 themes, 8 clusters of themes and 3 catagories were constructed. Final descriptions were found to be valid through the interviewee validation process. Essential themes of the menopausal experience which emerged were “coming of change”, “inclined to deny the in mind”, and “adapted life”. Menopause, as coming of change was the turning point in the women’s life cycle acompaning changes, in body and mind and marital life changes. Especially, the unpredictable menopausal changes were an opportunity to hide the fact of menopause and not to talk with anybody. Such a phenomenon reflected on the psychological attributes of menopausal woman such as an inclination to deny in the mind. Their experiences of menopause as adapted life were generally regarded as signalling the end of fertility and were interpreted as a natural developmental process that indicates a life transition. In conclusion, participants depicted the menopause as a natural stage in the life cycle. In order to help women have a positive life change and self accomplishment, nurses need to understand the essential themes of the menopausal experience. Thus, the importance of an open approach in eliciting the phenomena of menopause cannot be overemphasized. In conclusion, the results of this study suggest that exercise program is one of the effective interventions to improve the self-efficacy and also to lower the fatigue in the sample of female college students.
