본 논문은 부재 단위의 강성 재설계를 통해 전역 자유도 변위의 정량적 조절이 가능한 변위조절 기법의 개발을 목적으로 하고 있다. 이를 위해 부분적 강성변경이 발생했을 때 전체 구조물을 재해석하지 않고 관심 있는 특정 위치의 변위와 부재력만을 실시간 응답수준에서 재계산할 수 있는 부분재해석 기법을 적용하였다. 부분재해석 기법은 복잡한 미분계산이나 반복적인 구조해석을 수행하지 않아도 되는 단순한 기본개념의 기법으로서 계산이 효율적이고 강성변경 후의 변위를 바탕으로 변위에 대한 민감도를 계산하기에 수렴 속도가 빠른 장점을 가진다. 부분재해석 기법을 통해 전역 자유도에 대한 강성 변경 부재의 변위기여도를 계산하고 변위기여도에 따라 해당 부재의 강성을 변경시킴으로써 반복적 구조해석이나 민감도 해석 없이 특정 변위를 최소의 물량만으로 정량적으로 제어하는 변위조절 설계법을 제시하였다. 예제를 통한 검증결과, 부분재해석 기법이 고층건물의 횡변위제어에 효과적으로 활용될 수 있음을 확인하였다.

In order to evaluate the consistency of the serum estradiol pattern and response and to determine the influence of number of ovary on them in repeat cycles in the same patient, 57 cycles in 24 patients who underwent in Vitro Fertilization-Embryo Transfer or Gamete Intrafallopian Transfer in Seoul National University Hospital. The patients were stimulated by follicular stimulating hormone and human menopausal gonadotropin and classified as high(${\geqq}$400 pg/ml) and low(<400 pg/ml) response group according to preovulatory estradiol concentration and classified as three estradiol patterns (A,G.B) according to Jones criteria. Seventeen(89.5%) of 19 patients in when a high response to ovulation induction in their first cycle showed a high response. 40%(2/5) of the second ovulation induction cycle were low response in the patient whose first cycle resulted resulted in a low response. Serum estradiol pattern in the first ovulation induction cycle tended to be repeated in the second cycle. Women with high response tended to be more likely to have A and G patterns and less likely to have a cancellation than those with low response. One-ovary patients were at higher risk for inadequate ovulation induction response.

In human societies, there are various organizations which are unique and have different roles. Among them, hospital organization are much more complex than other organizations because of their multitude of professional groups each with its own goals. To achieve its purposes, hospital should manage each professional group effectively. Hospital nursing organizations are the core positions in hospitals for patient care. Therefore nursing organizations have have efficient nurse managers to lead nurses for their own purposes. First- line nurse managers have special tasks for patients and nurses, which include to motivating, managing communicating with the people. So they should have high self-efficacy, which is the belief that one can successfully perform the behaviors in question. Self-Efficacy of first line nurse managers that asked them for leading their staff, and their tasks, is essential to bring about self-realization of staff nurses through motivation and job satisfaction, taking advantage of sound surrounding which is able to operate her staff nurses in order to function efficiently. But there were few studies on the topic in a hospital setting. This study was designed to measure first-line nurse managers' self-efficacy. The subjects for this Study were 167 first-line nurse managers randomly selected from 18 university hospitals in Korea. The Self-Efficacy was measured using 'The general self-efficacy scale' developed by Sherer and Maddux(1982). The data were collected through questionnaires and analysed using SAS program, frequencies, percentages and Pearson' correlation coefficients. The results of this study were as follows : 1. The average of first- line nurse managers' self- efficacy was 66.7. 2. The correlation between first-line nurse managers' self- efficacy and general characteristics(age, education, career) was not significant. From the above findings, this study can suggest the following : 1. Repeat studies are needed in various hospital settings. 2. First-line nurse managers must be trained with special programs for each nursing organizations' purposes.

The purpose of this study was to obtain the basic element of patterns, which is the motif, from the existing art works and use it to create and simulate a variety of patterns to show the practical use of the computer. Natural dyed works of geometric shapes like squares and 1/4 of circles, each dyed with a different natural dyes, were produced and motifs were extracted. Then using the 4D box in Adobe Photoshop v.6.0, the developing pattern change and simulation effects when using different patterns and different repetition settings were examined. Observations were made as the motifs were replicated. Different patterns like a diagonal line, a square and a circle appeared. In order to find out the effects according to the changes, the motifs from work's square portions, circle centre, and the composition of eight motifs were extracted and used. The repeated patterns according to the extracted motifs simply showed that in the case of just repeating and arranging, square patterns appeared. By replicating and arranging, the motif and the allophone were matched and patterns with regular lines were formed, like a twill, pointed twill line. By setting the direction to Y and X in the repetition methodes, a typical half-drop arrangement or a brick pattern arrangement were formed according to 1/4, 2/4, 3/4, 1/3, or 2/3 in changes. Also the steepness of the slope changes quickly or in turn slowly as the rhombus shape appears. However in the case of a composed motif, an ogee pattern appeared. Lastly, by 3-D mapping patterns like a slant line, pointed twill patterns, diamond patterns, and the repeat patterns of a motif with a circle and a line combined, and a circle motif, an optical illusion could be observed.

Purpose: The purpose of this study was to find out the role conflict and ways of copying of nurses as underwriters worked at life insurance companies in Korea. Method: The subjects were 141 underwriters who were working at 4 major life insurance companies in Korea. For finding the role conflicts, Role conflict and Ambiguity scale developed by Rizzo, House & Lirtzman(1970) was used, For the ways of coping, Ways of coping scale developed by Lazarus et al. (1984) was used. The statistical method used were mean, percentage, t-test, ANOVA and Turkey test by SAS program. Result: The mean of role conflict was 2.76, and its subcategories were intersender conflict 2.95, sequential order interrole conflict 3.13, interarole conflict 2.69, organizational conflict 2.69, ambiguity from the outcome or responses to one's behavior 2.60, ambiguity from clarity of behavior requirements 2.61. The mean of ways of coping was 2.42 and its subcategories were problem focused 2.42, wishful thinking 2.26, detachment 2.09, seeking social support 2.49, focusing positive 2.72, tension reduction 2.08. There is statistically significant difference between single and married person i.e, single was high than married about role conflict. And also there is statistically significant difference among religion groups i.e., christian was high than none about ways of copying. Conclusion: The results of this study suggest that nurses as underwriters' role conflicts and ways of coping were different that of clinical nurses' and examining medical insurance nurses', Therefore it need more detail repeat studies.

In order to determine the effect of individual patient teaching through home visiting on compliance with sick role behavior and the blood sugar level in diabetic patients, to determine if the effectiveness of the education was still present four year later and to inquire as to the effective time for a repeat education program this study was done through two quasi-experimental researches. The subjects consisted of 52 diabetic patients. The results of the study may be summarized as follows ; 1. Hypothesis I, in which the compliance with sick role behavior, the knowledge on diabetes and the health belief of the experimental group who received a diabetic education program will be higher than those of the control group who didn't receive the diabetic education, was supported by both studies in 1984 and 1988, confirming the effect on diabetic patients of the individualized education through home visiting ; In the 1984 study : Compliance(t＝-11.7, p＜.001) Knowledge(t＝-5.41, p＜.001) Health belief(t＝-4.74, p＜.001) In the 1988 study : Compliance(t＝-4.85, p＜.001) Knowledge(t＝-2.85, p＜.01) Health Belief(t＝-2.99, p＜.005) 2. The Hypothesis II, the blood sugar level of the experimental group will be lower than that of the control, was rejected in both studies, 1984 and 1988. 3. The Hypothesis III, the compliance, knowledge and health belief of the expermental group who received the education program in 1984 will not last till 1988, was supported in part, in compliance and health belief, but not in knowledge. In conclusion those who received the education program twice with an interval of 2 weeks, 4 years ago still had knowledge of diabetes but compliance and health belief had disappeared.

Purpose : The purpose of this study was to understand the correlations between ego-resilience, self-efficacy and Satisfaction of Department on Nursing Students. Method : The subjects of this study were 352 nursing students in K college. The data collection period was from April 3, 2017 to April 20, 2017. The collected data was processed using SPSS 21.0 and were analyzed using frequency, means, standard deviation, t-test, ANOVA, Scheffe's test and pearson's correlation coefficient. Result : The mean scores for ego-resilience, self-efficacy and department satisfaction of the nursing students were 2.75 (${\pm}1.00$), 2.86 (${\pm}0.95$) and 3.72 (${\pm}0.92$) respectively. The ego-resilience score of the nursing students was significantly differed according to their religion (F=4.39, p=.002), choice motivation (F=3.99, p=.004), and relationship with friends (F=13.53, p=.015). The self-efficacy of the nursing students was significantly different by religion (F=3.18, p=.014). The department satisfaction of the nursing students also differed according to choice motivation (F=7.54, p= .007), and relationship with friends (F=11.66, p=.001). There was a positive correlation between ego-resilience and self-efficacy (r=.608, p<.01), between ego-resilience and department satisfaction (r=.342, p<.01), between self-efficacy and department satisfaction (r=.256, p<.01). Conclusion : The results of this study suggest the following: It is necessary to repeat the study with expanded number and scope of subjects in order to increase nursing a students' interest in Satisfaction of Department. It is necessary to develop programs for enhancing nursing students ego-resilience and self-efficacy which will result in a higher degree of department satisfaction.

Since the 1980's, despite the conclusion of a number of studies in Western countries focusing upon weight maintenance there has been no similar research in Korea which takes into account the contrasts of culture and eating habits between east and west. In order to identify eating, snacking and exercise behaviors, 24 female university students who have maintained weight for at least a year were enrolled fur an 11 day study. Participants were required to sign into the program and complete the questionnaire, answering questions by concerning what they ate and did everyday. After excluding unanswered questions, data over 11 days were exported into the Microsoft Excel spreadsheet, then both ANOVA and Kendall's tau correlation were applied with SPSS. 75% of weight maintainers had normal BMI (18-23.5) in relation to Korean standard, and appeared to eat a main meal smaller than moderate in portion size. Only two days showed that amount of breakfast eaten negatively correlated with lunch (p < 0.05), while no correlations between amounts of lunch and dinner eaten over all study period. Compared with breakfast or lunch, dinner was usually larger in portion size, but some variables such as TV viewing, restaurant meals, number of people at dinner table seemed not correlated with amount of dinner eaten. In addition, the weight-maintainers reported they rarely consumed snacks or sweetened beverages. Unlike their western counterparts, ffw participants reported that they took part in regular exercise during the day, which may lead us to the conclusion that these young female weight maintainers seem to maintain their weight with eating behaviours such as 'eat small portion', 'avoid snacking' and 'avoid soft drinks' rather than doing regular exercise. The study did not include a control group, and was foreshortened due to technical difficulties so it may be necessary to repeat the study while considering these two points.

Spatial multiplication phenomenon, expressed through de-constructive trend since the late of 20C, have got changed existing fixed and dis-variable space to smooth, fluid, and changeable space. Ex-form and fluidity of new spatial paradigm have been focused through lots of scientific theories studied between digital thought and indeterminacy and rankless nature phenomena. In 21C fashion, indeterminate and irregular form and space have been crested continuously, which could not explain simply according as the fluidity theory Different from the space crested for multi-function and multipurpose, this is revealed the characteristics of chaosmos that communizes the order and the disorder, deconstruction and creation. Ex-formal space of fashion have shown the relationship of de-centerizing, de-territorial, and do-structural phenomenon among different fashion elements. This paper intends to understand the concept of ex-form, and study expressive manners of ex-formal space of 21C fashion, and conclusion as follows. 1) Overlap changes single space of fashion to multi-layered space through the repeat system of pleats, origami, and folding. 2) Ex-gravity expressed in deviation of the gravity acting vertical direction, for example, twisting, curve, winding, portion. 3) Morphing is shown the change process from single fixed form to different complex form. 4) Blurring is expressed in re-combination and re-arrangement among elements of fashion. 5) Blob shows hybrid fashion space through the liberal compounding and separation of a lot of different elements.
