The purpose of this study is to analyze the type of ego states and stress coping style on female college students who are in the course of nursing study. This study is performed in the view of Transactional Analysis and designed to scrutinize descriptive correlations between the type of ego states and stress coping style. The subject is consists of 144 freshmen and sophomore, 138 junior and senior students group, who are students of K nursing college located in Seoul. The sampling investigation period is on Sept. 14, 2002 to Oct. 26, 2002. The measuring instrument used for Transactional Analysis ego state is 50 items Ego-gram research paper devised by Dusay(1997). For studying coping style, Folkman & Lazarus's measurement(1984) was adopted, which is translated and modified by Han, and Oh,(1990). Health states is adopted by standardized health inspecting instrumental table (Cornell Medical Index:CMI) which is designed for Korean people by Ko and Park(1980) Statistic average and standard deviation were generated by using SPSS PC+, t=test and Pearson correlation. The results were as follows: 1) In the type of ego states on both groups indicated the arithmetic apex NP(maximum value), then the point A was high and the data made a down slope to point AC. In the comparison to type of ego states between two groups, only at point CP, the data value of upper year students represented higher than that of lower year ones by c(t=2.28, p=.023). 2) Stress coping style of whole students were highly and affirmatively dedicated to research. Especially hopeful aspect(t=.67, p=.05), relaxation of tension(t=-2.16, p=.03) made significant difference each other in the view of arithmetic calculation. 3) In view of nursing students' physical health states, there is significant difference in past history(t=2.50, p=.013) and in case of mental health states, there are considerable discrepancies between lower group(73.52) and upper group(75.11)(p<.05). In view of all field, state of tension(t=2.13, p=.048) has difference. 4) While verifying coping style in terms of ego states level between lower and upper students group, In type CP, high level ego states group indicated significant difference on stress coping style area than low leveled group and made such sequences as the central point of problem, In type NP, sequences such as the central point of problem, In type A, the central point of problem, In type FC, hopeful aspect and In type AC, hopeful aspect and indifference were derived significantly different (p<.05). 5) While verifying health state differences in the level of lower and upper ego states, In type FC, low level group(150.29) marked higher point than upper group(145.19), there is remarkable discrepancy and so did whole health state(p=.014), In type AC both mental state(p=.000) and whole health state (p=.015) showed differences. 6) When analyzing correlations between whole students' ego states, copying style and health state, all type of ego state showed differences(p<.001). In correlations between ego state and health state, in type FC physical state had an apex and there are inverse correlations among the other types. Especially, type FC showed inverse correlations with great discrepancies(p<.05). In mental state, type NP(${\gamma}=.198$, p<.001) and type A(${\gamma}=.166$, p<.05) represented straight correlations with remarkable differences. Especially, In type AC showed inverse correlations(${\gamma}=.282$, p<.001). In case of correlations between copying style and health state, indifference(${\gamma}=-.157$) and relaxation of tension(${\gamma}=-.158$) presented great difference(p<.05). In mental state, central point of problem and search for social support showed straight correlations with great discrepancies(p<.05), hopeful aspect and indifference showed inverse correlations with considerable differences(p<.001).

This is a study that examines the fashion changes in the 20th century in terms of various subcultures in the period. Starting from defining the concept and the developing process of subculture, this study traces the history of subcultural styles from 1930s to 1990s, focusing on the way each generation resisted the main stream through its styles. This study is intended to provide a theoretical frame on the understanding of subcultural styles, with a close examination of its formative and developing process and characteristics. This study understands subcultural style as a way of deviate or resistant expression within a society. It differentiates itself from the main style by deliberately and publicly asserting its own identity, and, as a result, realizes in the form of fashion its repressed subconsciousness, resistance to the alienation from the society, and deviation from the normative ethics and morality of a society. The four types of subcultural styles presented in chapter 4 are based on their form of resistance, and they are classified and analyzed as follows: The first type is revision, which tries to revise and change the given form by adding new elements. There are two kinds of revision, one is dressing up, which dresses for success, and the other is minimal dressing. Hyperbole is the second type, which resists by emphasizing or hyperbolizing the main stream with its erotic, nihilistic, or dynamic forms. Two kinds of hyperbole are examined, one is hyperbole of masculinity, and the other is ostentatious hyperbole. The third type is reversal and rejection, which reverses the forms from the established sign system into its own secret code, or rejects the traditional taboos. This type include no dressing, and the reversal of sex identity. Isolation and redrawal is the fourth type, which tries to distance itself from the ritual code of the day. This type is divided into dressing of the escape from time, and dressing of the escape from space. The first group of this type is characterized by nostalgia or futurism. An emphasis is given on ethnicity, naturalism, or a closed space within a city in dressing of the escape from space. In conclusion, it can be said that subcultural style puts the foremost importance on individual freedom. Since 1990s, the distinction between the subcultural styles and high fashion gets somewhat blurred, while the liberal, sexual, life stylistic tension between the two groups are heightened.

The data were analyzed by using an S. P. S. S. computerized program for mean, standard deviation, percentage and paired t-test. The results of this study were as follows: 1. The increase in $PaO_2$ after hyperoxygenation and hyperinflation was highly statistically significant(p=0.041), and the increase in $PaO_2$ immediately after suctioning was not significant (p=0.752). The time of lowest $PaO_2$ was 30 seconds after the endotracheal suction. 2. The occurrance of cardiac arrhythmia after the endotracheal suction included sinus tachycardia, sinus arrhythmia, sinus bradycardia, premature atrial contraction (PAC), and premature ventricular contraction (PVC). The most frequent cardiac arrhythmia was sinus tachycardia (a subjects). Sinus arrhythmia was observed in 5 subjects and continued till 10 minutes after suctioning in two of these. Sinus bradycardia occurred in only 3 subjects and among them, 1 subjects shows sinus arrythmia till 10 minutes after suctioning along. PAC was observed in only one subject and continued till five minutes after suctining along with sinus arrhythmia. PVC was observed in three subjects: it lasted for only 30 seconds after suctioning in two subjects. but continued for 10 minutes after suctioning in the third. 6 subjects manifested two kinds of Cardiac arrhythmia Three of them showed sinus tachycardia with PVC, another 2 showed sinus bradycardia with sinus arrhythmia, and the other subject showed sinus arrhythmia with PAC. 3. The increases in heart rate during the endotracheal suction immediately after and at 30 seconds after suctioning were statistically significant (p=0.005). The increase in heart rate at one minute after suctioning was also significant (p=0.023). The increase in heart rate continued until 10 minutes after the endotracheal suction, but was not statistically significant In this study, endotracheal suctioning with hyperoxygenation and hyperinflation was effective in preventing a decrease in $PaO_2$ after suctioning, but not in preventing cardiac arrhythmias. Nurses should be aware of the complications of endotracheal suctioning and do effective hyperoxygenation and hyperinflation before and after suctioning. Further research is needed to develop a efficient endotracheal suction method which will minimize complications. This study needs to be replicated with different population of patients intubatted or having a tracheostomy, specifically, patients who cardiac or pulmonary desease.

스트레스 자극에 대한 심혈관계 및 교감신경계 과활성화 반응은 향후 심혈관계 질환 발생 및 심장 돌연사의 위험을 증가시킨다. 음악 청취는 자율신경계 기능을 향상시켜 안정 시 긴장 이완을 유도하는 것으로 알려져 있으나 음악이 스트레스 상황에서의 과도한 심혈관 반응을 완화 시킬 수 있는지에 대한 연구는 부족하다. 본 연구는 음악청취가 스트레스 자극에 대한 심혈관 반응성을 완화시켜 줄 수 있을지 검증하였다. 15명의 건강한 성인(남자 9명, 여성 6명)을 대상으로 무작위 교차 실험 설계로 진행하였다. 음악 처치는 음악을 30분간 청취하였고 통제 처치는 30분간 휴식을 취하였다. 냉압박 검사로 교감신경계를 자극하였으며, 변인으로 심박수, 상완 및 중심동맥 혈압과 심박변이도(heart rate variability)를 측정하였다. 연구 결과, 음악 처치와 통제 처치 모두 냉압박 검사 중 심박수와 혈압 반응이 유의하게 증가하였으나(p < .001), 처치와 시기 간 상호작용 효과는 유의하지 않았다. 회복 구간에서 상완동맥 수축기혈압이 음악처치 그룹에서만 유의하게 감소하였다(p = 0.008). 나머지 혈압 변인들도 음악중재 그룹에서 더 완화되는 경향이 나타났으나 통계적으로 유의하지는 않았다. 심박변이도는 음악 처치 전후로 음악 처치 그룹에서만 SDNN(standard deviation of the NN intervals), TP(total power)와 HF(high frequency)값이 유의하게 증가하였다(p = 0.001, p = 0.002, p = 0.011). 따라서 음악 청취는 스트레스 이후의 회복력을 촉진시킬 가능성이 있다. 음악 처치의 구체적인 변인들을 고려하여 과도한 심혈관 반응에 대한 보호 효과로서의 음악 청취에 대한 추가적인 연구가 필요하다.

The purpose of this study was to identify risk factors related to sexual function of women with coronary artery disease, and to determine the predictors of sexual function. The study design, a descriptive correlational study, was done through structural questionnaire and interview. A total of 50 subjects from C University Hospital at Kwang-ju city who have undergone coronary angiography at department of cardiology were observed and interviewed from Feb. 22, 1999 to March. 23, 1999. The number of affected vessels, the level of total serum cholesterol, and the ejection fraction of 2-D echo cardiography were analyzed to evaluate the severity of coronary artery disease. And also type A behavior pattern, health behavior, Brief Index of Sexual Functioning for Women (BISF-W) were measured. The data obtained were analyzed using percentage, mean and standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis via SPSS PC+. The results of this study were as follows: 1. The mean age of the subjects were 58.1 and 72.0% of those have been married over 30 years. Seventy two percentage were unemployed and monthly family income of 56.6% was less than 1,000,000 won (approximately $ 840). Eighty percent were in their postmenopausal state, and the frequency of sexual intercourse of 84.0% were two to three times per month. 2. The scores of type A behavior pattern were from 16 to 38(mean 24.94) and health behavior ranged from 21 to 43(mean 31.2). Abstinence from smoking, alcohol, and caffeine were best compliant factors and weight control and exercise were least abided ones. The result of 2D-ECHO EF showed that the half of the subjects were abnormal, and 24% had more than 240mg/dl of total serum cholesterol. The coronary angiography showed that 64% of the subjects had more than one affected vessels. 3. The predictors to explain the factor score of 'orgasm' were number of health examination, the pre- or post-menopausal state, protestant, number of coronary vessel affected, level of serum total cholesterol, and comorbid group of hypertension and diabetes, and it's total variance accounted for 52.4%. The predictors to explain the factor score of 'sexual activity' were comorbid group of hypertension and diabetes and type A behavior pattern, which accounted for 22.4% of total variance. The predictors to explain the factor score of 'sexual satisfaction' were type A behavior pattern, no religion, exercise, level of serum total cholesterol, and pre or post menopausal state, which accounted for 52.1%. The predictors to explain the factor score of 'sexual desire' were the period of marriage, type A behavior, employment or unemployment, and weight control, which accounted for 43.2%. The predictors to explain the factor score of 'external force of sexual functioning' were physical overload and exercise, which accounted for 41.1%. The predictors to explain the factor score of 'sexual activity' were family monthly income, catholics, and exercise, and which accounted for 35.4%. Above results lead us to some consensus that sexual function of women with coronary artery disease is related to various factors including vasogenic factors such as total serum cholesterol level, number of coronary vessel affected, an endocrinal factor such as menopausal state, and type A behavior pattern as a sociopshychological factor. And also health behaviors such as fitness care, overwork, weight control, and emotional tension are contributed to sexual function.
