This work was done for 9 patients having experience of a herb medical treatment after being diagnosed as CVA during a year from January, 1996 to December, 1996 by using an ethnographic research method. The summarized results of this research are following. Ⅰ. THE EXPERIENCE OF THE ILLNESS First, the falling-ill phase is the time that they have the first stroke of paralysis and the decision pattern of medical institution' comes out. The emotional experience in the period is something like 'flustration', 'anxiety', 'despair', and 'expectation'. Second, the active-treatment phase is the time that the patients as well as their family or care giver not only show the positive attitude and actively participate in the illness treatment but also show a lot of interest in medical institutions and activities of health recovery. There is a primary factor of the continuation of treatment as an experience of treatment and being crushed and sensitivity as an experience of the illness. Third, the rehabilitation phase is the time that the patients or their family become tired and insensitive to the treatment and recuperation, and then reduce the treatment activity. There is a primary influence factor of the discontinuance of treatment as an experience of treatment and physical experience and emotional experience as an experience of the illness. The physical experience is divided into 'personal-hygiene care', and 'the sphere of activity' The emotional experiences are 'blaming someone', 'contempt' and 'despair' as a negative experience and 'hope' as a positive experience. Ⅱ. COPING STRATEGY There are a physical coping, an emotional and mental coping, a social coping, and a spiritual coping as a coping strategy used for the patients to overcome their illness and adjust themselves to their altered life. First, the physical coping comes out as 8 categories, 'using an auxiliary tool', 'doing exercise', 'protecting', 'improving their diet', 'taking care of something', 'using subsidiary medicines', 'trying a folk remedy', and 'having interest in their health'. Second, for the emotional and mental coping, there are 'accepting' and 'trying' as a positive coping and a failure of control as a negative coping. Third, the social coping is appeared as 'being supported'. Fourth, the spiritual coping is recognized as' recourse to God' and 'preparation of death'. After all, the elderly CVA patients in an agricultural area choose the act of treatment based on the traditional belief and the relationship with a caretaker. A personal health can be maintained by taking care of themselves and controling their mind, and the overcome of the illness is decided on the basis of traditional concepts and cultural principles in which the patients as well as the family, neigbors and take carers should work out together and cooperate with each other in order to achieve that.

In vision measurement systems based on structured light, the key point of detection precision is to determine accurately the central position of the projected laser line in the image. The purpose of this research is to extract laser line centers based on a decision function generated to distinguish the real centers from candidate points with a high recognition rate. First, preprocessing of an image adopting a difference image method is conducted to realize image segmentation of the laser line. Second, the feature points in an integral pixel level are selected as the initiating light line centers by the eigenvalues of the Hessian matrix. Third, according to the light intensity distribution of a laser line obeying a Gaussian distribution in transverse section and a constant distribution in longitudinal section, a normalized model of Hessian matrix eigenvalues for the candidate centers of the laser line is presented to balance reasonably the two eigenvalues that indicate the variation tendencies of the second-order partial derivatives of the Gaussian function and constant function, respectively. The proposed model integrates a Gaussian recognition function and a sinusoidal recognition function. The Gaussian recognition function estimates the characteristic that one eigenvalue approaches zero, and enhances the sensitivity of the decision function to that characteristic, which corresponds to the longitudinal direction of the laser line. The sinusoidal recognition function evaluates the feature that the other eigenvalue is negative with a large absolute value, making the decision function more sensitive to that feature, which is related to the transverse direction of the laser line. In the proposed model the decision function is weighted for higher values to the real centers synthetically, considering the properties in the longitudinal and transverse directions of the laser line. Moreover, this method provides a decision value from 0 to 1 for arbitrary candidate centers, which yields a normalized measure for different laser lines in different images. The normalized results of pixels close to 1 are determined to be the real centers by progressive scanning of the image columns. Finally, the zero point of a second-order Taylor expansion in the eigenvector's direction is employed to refine further the extraction results of the central points at the subpixel level. The experimental results show that the method based on this normalization model accurately extracts the coordinates of laser line centers and obtains a higher recognition rate in two group experiments.

This study aimed at investigating the level of high school students' entrance exam stress and mental health first and also investigating if the entrance exam stress and mental health are related to gender, grade, character type, parenting style and economic status. This is expected to be used as a fundamental data for the development of health education program on high school students' stress and diagnosis of their mental health. To achieve those goals above, the questionnaire was used and the sample consisted of 600 students from general high schools in a large city, C and in a smaller city, A in Chungnam province through questionnaire and the conclusion, which was based on 582 proper questionnaires from the 600 questionnaires, through variable analysis, correlation analysis and multi-regression, is below. First, according to the information provided by respondents, the result showed the relationship between those background variables and the entrance exam stress and mental health level. As the students are more introverted and the parenting style is more authoritative, the entrance exam stress is higher and the mental health level is higher as the parenting style is more authoritative and the economic status is lower. In gender, the entrance exam stress level was high for male students in regard to parents pressure. For female students, it was due to the insufficient free time. In test performance, the good grade group showed high stress level when they don't have enough free time and the poor grade group showed high stress level when they have test tension and poor test performance. In character style, the introverted group showed high stress level in future uncertainty. In parenting style, the authoritative group showed significantly high level in all four sub-factors and there is no significant relationship with the stress level and economic statue. Female students reported higher mental health level than male students in somatization and depression. In academic achievement, the poor grade group showed high level in obsession, fear-anxiety and psychotism. In character style, the introverted group showed high level in sensitivity towards others and depression. And in parenting style, the authoritative group is higher in 9 sub-factors than the other two groups in the factor, economic status. The lower economic status group showed high mental health problem level in this order; in obsession, sensitivity towards others, depression, paranonia and psychotism. Second, the results revealed that there is a significant difference among the groups after comparing and analyzing the relationship between the mental health level according to the three groups, the first, second and third group divided by the degree of entrance exam stress. And the higher the entrance exam stress is, the higher the mental health problem level is. Verification showed that there was obvious difference among the groups. the entrance exam stress was positively correlated with the mental health level. The lack of free time, future uncertainty, test anxiety/poor test performance and parents pressure, these factors, in that order, were correlated with the mental health level. when the prediction variables which influenced on mental health are analyzed, test-anxiety/poor test performance was found to be related to mental health most. And after the factor, test-anxiety, future uncertainty and the lack of free time were listed(ranked), however results did not show any correlation with parents' pressure.

표준 k-${\varepsilon}$, RNG k-${\omega}$ 그리고 k-${\omega}$ SST 난류 모형과 VOF (volume of fluid)기법을 이용하여 사각형 광정위어를 통과하는 난류 흐름의 수면 변화와 유속분포를 수치모의 하였다. 지배방정식은 2차 정확도의 유한체적기법을 이용하여 해석하였으며, 두 개의 서로 다른 격자해상도에서 계산을 수행하여 수치해석 결과의 격자 민감도를 분석하였다. 계산 결과를 Kirkgoz et al. (2008)의 실험 결과 그리고 Moss (1972) 및 Zachoval et al. (2012) 무차원화된 실험값과 비교 분석하여 적용한 수치모형의 정확도를 평가하였다. 수치모의 결과는 사각형 개수로에 설치된 광정위어 흐름의 실험결과들을 합리적으로 예측하고 있으면 적용한 난류모형에 따라서 두 개의 주요 흐름분리 영역에서 계산 결과에 차이가 있는 것으로 나타났다. 표준 k-${\varepsilon}$ 모형은 이들 두 개의 흐름분리영역의 크기를 과소산정하고 있으며, k-${\omega}$ SST 모형은 위어 전면부에서 발생하는 흐름분리 영역을 다소 과대 산정하는 것으로 나타났다. RNG k-${\varepsilon}$ 모형은 전반적으로 양호하게 두 흐름분리 영역을 예측하는 한편, k-${\omega}$ SST 모형은 위어 상류부 모서리에서 발생하는 박리거품의 발생 형태를 가장 잘 예측하는 것으로 나타났다.

This study proposes a process to design and analyze stage costumes by design elements for the costumes of the Korean traditional music cantata 'I Will Rise'. This study states fundamental references to make costumes of similar performances in the future and develop costume designs based on the format of a play. The findings are as follows. First, the costume production process of 'I Will Rise' is conducted in the order of directing intentions and script analysis, costume design, miniature production, costume production, costume modification, run, and post-production. Second, an overall Korean silhouette is expressed through the creation of costumes based on the construction of Korean traditional clothing (hanbok); however, from a detail perspective, a modernistic sensitivity is expressed through the use of modern elements (wing shoulders attached to shoulders, narrow ribbons made in a string form, and wristlets and belts) not found in hanboks. Third, tie-dying is applied to the costume colors of each character to highlight the traditional and unique feeling of dye and symbolic colors that effectively represent each role used to communicate the storyline and character emotions to the audience. Fourth, materials for costumes are cotton and linen (frequently used to create the texture of a Hanbok) as the costume of each character is emphasized to the use of additional and detailed materials such as artificial leather, hemp, and silk.
