The experiment was carried out on eight healthy male subjects of 19-22 years old and they were maintained The experiment was carried out on eight healthy male subjects of 19-22 years old and they were maintained under the rice diet, the general mixed diet and the high animal protein diet for 7 days of each experimental period, respectively. The composition of each diet was indicated in Table 3. The allowance' of each nutrient per head per day in each diet were as follows. a) In the rice diet; protein:139.5 g (animal source:64.6 g, vegetable source:74.9 g), fat:25.3 g (animal source:11.3 g, vegetable source:14.0 g), carbohydrate: 644.0 g, calcium:982.3 mg, phosphorus: 2369.2mg, thiamine:2.1 mg, riboflavin: 1.6 mg, and 3211 Cal. b) In the general mixed diet; protein: 97.4g (animal source: 10.5 g, vegetable source: 86.9 g), fat:40.3 g (animal source:7.1 g, vegetable source:33.2 g), carbohydrate:620.7 g, calcium:887.1m g, phosphorus:2200.8m g, thiamine: 1.8m g, riboflavin:1.9m g, and 3158 Cal. c) In the high animal protein diet; protein: 135.6 g (animal source:68.8 g, vegetable source:66.8 g), fat:32.5g (animal source:17.9 g, vegetable source:14.6 g), carbohydrate:930.9 g, calcium: 626.0 mg, phosphorus: 1998.9 mg, thiamine: 1.5 mg, riboflavin: 1.5 mg, and 3194 Cal. The absorption rates of protein, fat, carbohydrate, calcium, phospherus, thiamine and riboflavin in each diet were observed. The results obtained were summarized as follows: 1. The absorption rates of protein and fat in the rice diet were 88.t % and 71.3.%. 2. The absorption rates of protein and fat in the general mixed diet were 83.4% and 86.4%. 3. The absorption rates of protein and fat in the high animal protein diet were 86.8% and 82.4%. 4. The nitrogen balances in the rice, the general mixed and the high animal protein diet groups were +5.7g, +2.3g and +4.0g respectively. 5. The absorption rates of carbohydrate in each diet were all above 95 % and so seemed to be almost completely absorbed except the cellulose in the diets. 6. The calory utilization rates in each diet were all above 93 %. 7. The minimum absorption rates of protein, fat and calory were 83.8%, 63.3%, and 89.7% in the rice diet, 80.0%, 80.9% and 85.9%, in the general mixed diet and 83.6%, 75.7% and. 89.3 % in the high animal protein diet respectively. Therefore, it is assumed that these data might be significant in practical use. 8. The protein absorption rates of the rice diet (88.1 %) was better than that of the general mixed diet (83.4 %). 9. The fat absorption rates of the general mixed diet and the high animal protein diet (86.4% and 82.4%) were signficantly better than that of the rice diet (71.3%). 10. The calcium absorption rates of each diet, rice diet, the general mixed diet and the high animal protein diet were 41.6%, 36.0%, and 27.7%, respectively. 11. The phosphorus absorption rates of each diet were 51.4%, 56.0% and 52.3%, respectively.12. The phosphorus absorption rate seemed better than that of calcium. 13. The thiamine absorption rates of each diet seemed 27.0 %, 42.9 % and 29.5 %, respectively. 14. The riboflavin absorption rates of each diet seemed above 30.6%, 27.1%, and 39.3% respectively. 15. The excretion amounts of thiamine or riboflavin were much more than the amounts ingested of the both vitamins. Therefore, the certain amount of both vitamins seemed to synthesize in the intestine.

The purpose of this study was to analyze the characteristics of socio-demographic, organizational culture, organizational conflict and organizational commitment, and to examine the interrelation of influential factors in the organizational commitment. The data for this study were collected through a self-administrated survey with a structured questionnaire to 1,027 subjects from several medical doctor staff members, nursing staff members, administration staff members, pharmacist, and technical expert of eleven hospitals. The data were collected by self-reporting questionnaire from July 29 to September 7, 2002. In this analysis frequency test, t-test, ANOVA, multiple regression were used. The main results of this research is as following; 1. According to socio-demographic characteristics the respondents' level of the organizational commitment was higher in a administration staff members than others, for males than females, and for employees aged more than forty, as working for longer time, and as higher level of the working position. 2. According to the organizational culture characteristics the progressive culture, affiliative culture, and task-focused culture among many types of organizational culture were moderately and positively correlated with the level of the organizational commitment while the hierarchical culture was negatively correlated. 3. According to the organizational conflict characteristics as the respondents who got less conflict experience in the organization, their level of the organizational commitment was higher. And, technical conflict experiences were expressed greater than hierarchical conflict experiences. 4. According to the job satisfaction characteristics as his or her satisfaction that is about the promotion, working itself, salary, and fellowship in the organizational was higher, the level of the organizational commitment was higher. The most important factor of the satisfactions was the fellowship among the respondents while the level of job satisfaction for the promotion and salary was average. 5. Overall, according to the result of Multiple Regression as older age and longer working hours, the level of the organizational commitment was higher and as a higher level of the satisfaction for the promotion, working itself, salary, and fellowship in the organization, it caused more effective factors for the organizational commitment. 6. According to the result of Multiple Regression for the doctor staff members in special hospitals rather than general hospitals the hierarchical culture and task focused culture was positively correlated with the satisfaction of working itself while hierarchical conflict factors in the organizational conflict characteristics was negatively correlated with the organizational commitment. For the nursing staff members the affiliative culture and the job satisfaction for the promotion, working itself, salary, and fellowship were positively correlated with the organizational commitment. For the administration staff members as the job satisfaction for the fellowship was positively correlated with the organizational commitment. For medical and pharmacy staff members as more working experience, correlation with the organizational commitment was positive. Besides, as he or she has a high perception of the affiliative culture, it caused statistically more effective factors for the organizational commitment. For the skill and technicians, male worker expressed greater organizational commitment in the organization than female worker. And also older age along with higher education also showed higher organizational commitment. Moreover, the job satisfaction for the fellowship was positively correlated with the organizational commitment. This study identified the major effective factors of the organizational commitment and analyzed the differences among the job category. In that respect, it is significant for the study to be able to provide a reference for managing hospital of industrial accident and organizational development. However, this study has a problem, which is not to identify a valuable model for examining the relationship between organizational factors such as organizational culture, conflict, satisfaction, and commitment. Therefore, further study is needed and strengthened in the field of organizational commitment for hospital for industrial accident.

This study is aimed at examining the ethical values of EMT students. The results below are based on the revised questionnaires, which can be applicable to EMT from the original questionnaires developed by Lee(1990), with a sample of 124 students consisting of 63 first and 61 second year students, conducted November 2-8, 2001. Data were analyzed using SPSS in terms of means, standard deviations, t-test, ANOVA, Pearson's correlation coefficient. The results are as follows: 1. In the area of Human life, all subjects showed utilitarian disposition. All respondents perceived the item "When patients recognizing there is no hope for survival ask for euthanasia, it is ethically right to accommodate their opinions." as the most utilitarian item, whereas they perceived the item "When an hopeless patient is on cardiac arrest, it is ethically right to do CPR as the most deontoogical item. 2. In the area of patient relationship, all students of two groups took on deontoogical characteristics, but there were no statistically significant differences between two groups. All students perceived an item "EMT have to keep it secret if patients disclose their suicide intentions and ask for absolute secrecy" the most utilitarian item, whereas they perceived an item "Even though patients act and speak in a very rude manner, EMT people should do their best to provide care for patients." as the most deontoogical item. 3. In the area of task relationship, first year students perceived an item "Given time limitations, it is ethically right to give priority to the patients who can be rehabilitated over the patients who can't be fully recovered." as the most utilitarian item, whereas second year students perceived an item "Under no circumstances should any placebo be administered to patients." as the most utilitarian item. All students perceived an item "When EMT students see an unconscious person lying in the street, they have to give him/her emergency treatment." as the most deontoogical item. 4. In the area of coworker relationship, all students of two groups took on deontoogical disposition, but there were no significant differences between two groups. All students of two groups perceived an item "Suppose you are regarded as the person who would be promoted. However, you think that your coworker is more competent than you. In that case you should tell your supervisor about your coworker." as the most utilitarian item. First year students perceived an item, whereas second year students perceived an item "When you observe coworkers' misconduct at work, it is ethically right to ignore their misdeeds." as the most deontoogical item. 5. This study demonstrated that for the first year students, there is a correlational relationship between areas of human life and task relationship, and between areas of task relationship and coworker relationship, whereas for the second year students, there is a correlational relationship between areas of human life and task relationship. 6. In areas of human life and task relationship, there are significant differences according to attitudes toward EMT and attendance at ethics training sessions. In the area of coworker relationship, there are significant differences according to religion, attendance at ethics training sessions, and a code of ethics. Recommendations for future research, 1. Sample items to measure ethical values and the instrument tailored to the needs of EMT should be developed. 2. A longitudinal study to track ethical value changes according to the amount of work experience is needed. 3. A code of ethics and/or ethics training, which could apply in actual situations, should be implemented.

The Low Birth Weight infant birth rate in this country is a little more than 15 percent and is being increased. The survival rate of Low Birth Weight infant is over 90 percent and recently the rate runs is getting. However, because of the high risk of Low Birth Weight infant for handicap in growth, a preventive nursing intervention program for Low Birth Weight infant and their mother is considered to be necessary. Touch and massage, thus sensory stimulation has been considered to be important ensuring a normal growth of Low Birth Weight infant During the past decades sensory stimulation program has been used for premature and Low Birth Weight infants. Recently a study on the sensory stimulation for Low Birth Weight infants has bee n done in this country. Mother and infant relationship has a great influence on child's development. Especially, mother and infant interaction during one year after birth plays important role in child's social. affective and cognitive developments. But in the study of Low Birth Weight infants, the mother and infant interaction has been rare yet. However, there was no study effectiveness of the sensory stimulation on mother and infant interaction. In this respect, this study based on the importance of the nursing intervention, is intended to measure the effectiveness of the massage therapy in the aspects of weight, daily feeding amount, cortisolurine stress hormone and mother and infant interactions. This study has been conducted on the nonequivalent control group pretestposttest design in quasi experimental basis and Low Birth Weight infants from NICU of two Medical University Hospitals located in Taegu Metropolitan were selected in experimental group of 21 infants and control group of 20 infants. Data has been collected from May 1, 1999 to September 5, 2000. For the experimental group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00 - 11:00 hours in the morning and 19:00 - 20:00 in the afternoon) by nurse and mother. The electronic indicator scale (Cas Co. Korea) was used to measure infant's body weight. To determine urine cortisol concentration level under stress, rad immuno assay method was used. And to determine mother and infant interactions during feeding, tools developed by Kim Mi-Ye (1999) were used. Collected data were analyzed with SAS program using x-test, t-test, paired t-test and repeated measures ANOVA. Findings were as follows : 1. For the daily mean weight gain, the experimental group showed little higher than the control group, even though, there was no Statistically significant differences between two groups. 2. For the amount of daily mean feeding, the experimental group showed little higher than the control group, while there was no Statistically significant differences between two groups. 3. The level of wine cortisol concentration was increased in both groups, while no Statistical significance was shown between the two groups. 4. Mothers in experimental group were more likely to have higher mean scores in mother and infant interaction during feeding than mothers in the control group. Statistical significance was shown between the two groups(t= 5.78, P=.001). In conclusion, the massage therapy in this study showed with regard to even though through there was no statistically significance in the weight gain and urine stress hormone concentration. there was Statistical significantly higher in the mother and infant interaction during feeding. Based on the result of this study, it is considered that the massage therapy should be applied clinical practice and home to help a developmental growth and interaction of Low Birth Weight infants and mothers during the period of recovery.

Background: The purpose of this study was to determine the benefit of tertiary cytoreductive surgery (TC) for secondary recurrent epithelial ovarian cancer (EOC), focusing on whether optimal cytoreduction has an impact on disease-free survival, and whether certain patient characteristics could identify ideal candidates for TC. Materials and Methods: Retrospective analysis of secondary recurrent EOC patients undergoing TC at three Turkish tertiary institutions from May 1997 to July 2014 was performed. All patients had previously received primary cytoreduction followed by intravenous platinum-based chemotherapy and secondary cytoreduction for first recurrence. Clinical and pathological data were obtained from the patients' medical records. Survival analysis was caried out using the Kaplan Meier method. Actuarial curves were compared by the two tailed Logrank test with a statistical significance level of 0.05. Results: Median age of the patients was 49.6 years (range, 30-67) and thirty-eight (72%) had stage III-IV disease at initial diagnosis. Twenty six (49%) had optimal and 27 (51%) suboptimal cytoreduction during tertiary debulking surgery. Optimal initial cytoreduction, time to first recurrence, optimal secondary cytoreduction, time interval between secondary cytoreduction and secondary recurrence, size of recurrence, disease status at last follow-up were found to be significant risk factors to predict optimal TC. Optimal cytoreduction in initial and tertiary surgery and serum CA-125 level prior to TC were independent prognostic factors on univariate analysis. Conclusions: Our results and a literature review clearly showed that maximal surgical effort should be made in TC, since patients undergoing optimal TC have a better survival. Thus, patients with secondary recurrent EOC in whom optimal cytoreduction can be achieved should be actively selected.

The purpose of this study was to analyze risk factors for nosocomial pneumonia in patients admitted to NS ICU, and to provide a basic data to decrease respiratory nosocomial infection rate engendered from medical environments in NS ICU. The study site was the NS ICU at a university hospital located in Seoul, Korea. The subjects were 31 patients diagnosed with nosocomial pneumonia, who were selected from the initial list of 300 potential subjects who had been a) admitted between September 1999 and January 2000, and September 2000 and January 2001, b) resided at the NS ICU over 72 hours. The diagnostic standard of nosocomial pneumonia was based on the nosocomial infection guides of C university hospital. The data were analyzed using frequencies and logistic regression analysis. The sputums obtained from the subjects were cultivated and causal viruses were separated. The results were as follows: 1. The nosocomial pneumonia rate was $10.3\%$. There were 7 types of causal viruses separated from the sputum. and the most prevalent type of virus was MRSA as $62.2\%$. 2. The factors significantly influencing the incidence of nosocomial pneumonia included age, the residential duration at the NS ICU, GCS scores, diabetes mellitus, insertion of tracheal tube and its duration, tracheostomy and its length of insertion, the use of artificial ventilator and the length of its use, and the insertion of naso-gastic tube. The most significant risk factor among these was the insertion of tracheal tube (odds ratio=18.684. $95\%$ CI=6.849-50.974), followed by the use of tracheostomy (odds ratio=15.419, $95\%$ CI=6.615-35.942), the insertion of naso-gastric tube (odds ratio=14.875, $95\%$ CI=6.396-34.595), and the use of artificial ventilator (odds ratio=13.000. $95\%$ CI=5.633­30.001). 3. Regarding the use of the mechanical aids, the insertion of tracheal tube resulted in 12.968 times increase of the nosocomial pneumonia rate, and the use of artificial ventilator lead 6.714 times increase of the nosocomial pneumonia rate. One point increase of the GCS score resulted in the 1.210 times increase of the nosocomial pneumonia rate. For patients who had tracheal tube, tracheostomy, and artificial ventilator, one day increase of their residential duration at NS ICU lead 1.073 times increase of the nosocomial pneumonia rate. 4. In terms of duration of the mechanical aid usage, one day increase in the use of artificial ventilator engendered 1.080 times increase in the nosocomial pneumonia rate. One day increase of the residential duration at the NS ICU lead 1.604 times increase in the nosocomial pneumonia rate. As one point of the GCS score increased, 0.876 times decrease of the nosocomial pneumonia rate was reported. These study findings show that the risk factors significantly influencing the incidence of nosocomial pneumonia include the use of tracheal tube, tracheostomy, naso-gastic tube, and artificial ventilator. It is recommended that nurses working at NS ICU should pay more attention to the patients with these factors as the risky group for the nosocomial pneumonia, and thus make more active efforts to provide nosocomial pneumonia prevention strategies for them. In further studies patients admitted to the different types of ICUs such as internal medicine or surgery unit ICU will be also included, and more wide investigation of nosocomial pneumonia risk factors will be conducted through one-year longitudinal follow up.
