This study attempted to identify important problems of the factors related to the indwelling catheter with closed drainage and to enhance recognization of Urinary Tract Infection management to protect patients with indwelling catheter from UTI. We selected the 58 patients with indwelling catheter with closed drainage from md-surg. intensive care units, and general neurological and neurosurgical ward, in one hospital in Pusan, Korea from May 30 to October 15, 1993. Patients were examined by urinary analysis before inserting catheter and then by urine cultures three times. The obtained data was analized using an SPSS /PC$^{+}$ The statistical analyses employed here was the frequency, percentage and x$^2$-tests. 1. Analyses for Indwelling Catheter induced UTI and infection rates were found to be presented in patients related to the factors of being on antibiotic drugs (x$^2$=14.105, p=.000) and the duration of the indwelling catheter(x$^2$=58.0, p=.000), both of which were found to affect the UTI. 2. UTI rates according to the duration of the in-dwelling catheter were high 8.6％ for the 2nd day, 27.6 for the 4th day, and 36.2% for the 7th day, and as the duration for the indwelling catheter was longer, UTI rates were higher. 3. The UTI rates according to the duration of the indwelling catheter related re factors, on the 7th day, were high-52.0% for women, 37.0% for more than 50 years in ages, 30.0% for patients under sur-gery, 33.3% for altered mental states outsides the alert, 76.7% for patients not given antibiotic drugs, 36.4% for less than 3500cc of fluids intakes, it was found that these affected to increase the UTI. 4. Causative organisms of UTI were found ; E.Coli appears the most than all other isolated organisms in women and Klebsiella and Pseudomonas in men. For antibiotic susceptibility of causative organisms, all causative organisms were found to be susceptible to Sul -cefoperazone, Trim-prim, and unasyn and Pseudomonas mostly net susceptible.e.

This study is to develop the model on the joint employment system of occupational health nurse practitioners for medium or small sized enterprises in Korea based on the comparison opinions between employers and occupational health nurses (OHN). The data were collected by questionnaires from Oct. to Nov. in 1997. The number of subjects was 210 OHNs and 176 employers, response rate was 47.1% for OHNs and 23.2% for employers. The SAS PC program was used for the descriptive statistics. The results were as follow: 1. More than three years career was preferred for qualification of OHN by employers and OHNs. OHNs preferred that all instruments and materials should be equipped in each industry, but employers preferred that they should be equipped by OHN. 2. For the limit number of industries and employees per one OHN, employers preferred average 2.25 industries and 307 employees, OHNs preferred average 3.0 industries and 448 employees. Both of them preferred two times visit per week for all day long. 3. OHNs wanted that the local office of Ministry of Labor could act as mediator, but employers preferred direct contact individually. For the average wage, employers preferred 887,000 won per month, but OHNs preferred 1,960,000 won per month. 4. OHNs preferred the Korean Association of Occupational Health Nurse as the recruit agency. Finally, employers and OHNs have the opinions that they can choose this system depending on the condition. There is in need of development of effective strategy for this new system such as manpower development, cost-benefit analysis, establishment of occupational health service standard, advertisement for employers, and government supported project.

Purpose: Music intervention has long been used in research of patients undergoing surgical operation in reducing anxiety level and improve surgical outcome. However, there are few studies that have considered a patient's music preference. We investigated the effect of the tailored music intervention which chose music according to the patient's preference on anxiety level and vital signs. Method: The subjects were 50 patients who received regional anesthesia for surgical operation at D hospital in Pohang city from April, 2006 to November, 2006. All of the subjects were randomly assigned either music group (30 subjects) or non-music group (20 subjects). As the patients arrived in the operating room, vital signs were monitored until the subjects were transferred to the recovery room, while Spielberger's STAI-KYZ questionnaires were applied twice to measure preoperative and intra-operative anxiety. The data were analyzed by 2-test, t-test, one-way ANCOVA and repeated measures ANOVA using SPSS 12.0/PC+. Results: There were no significant differences between the two groups on vital signs. All of the vital signs increased when the subjects arrived in the operating room, but decreased quickly once the operation began, regardless of the groups. However, the music group reported significantly less intra-operative anxiety, compared to the non-music group (F=15.208, p<.000), when preoperative anxiety was treated as a covariance. Conclusion: The findings support that the use of music which was chosen by patients during the surgery significantly reduced patient's intra-operative anxiety during regional anesthesia.

In this study, we compare thermal performance between four different types of cold plates for humanoid robot cooling. Two commercially available cold plates made of copper have different dimensions and internal flow paths: One has $20{\times}20$ $mm^2$ base area with micro-channels and the other has $62.5{\times}62.5$ $mm^2$ base area with 85 round pin-fins. And two different types of cold plates of $20{\times}20$ $mm^2$ base area with 7 mm high are made of PC (polycarbonate), which aims to reduce the weight of cooling system. All cold plates are mounted on a $20{\times}20$ $mm^2$ copper block with two cartridge heaters of 30 $W/cm^2$. The overall heat transfer coefficient and thermal resistances for the liquid-cooled cold plates are obtained. The copper cold plate with micro-channels showed the best performance. Polycarbonate cold plates display fairly good thermal performance with more reduced system weight.

Genetic diversity of forty-four strains of Xanthomonas campestris pv. vesicatoria from diverse geographic origins was investigated using random amplified polymorphic DNA (RAPD) of genomic DNA. One hundred and thirty-seven amplified fragments were produced by polymerase chain reaction with a set of 14 random primers, and the sizes of amplified DNA fragments ranged approximately from 0.3 to 3.2 kb. Cluster analysis of genetic similarity among the strains generated the dendrogram that clearly separated all strains from each other. The 44 strains of X. campestris pv. vesicatoria were classified into 4 major genomic DNA RAPD groups and 15 subgroups at the genetic similarity of 0.60 and 0.92, respectively. The strains from foreign countries formed discrete subgroups, but the United States strain 87-77 clustered closely with some of Korean strains together. Thirty-nine Korean strains were classified into 11 subgroups, and especially Masan strain Ms93-1 clustered distinctly far from the other Korean strains. RAPD polymorphism suggests strongly the occurrence of genetic differentiation of X. campestris pv. vesicatoria and the existence of genetically distinctive subgroups among the populations in Korea.

The hospital is not the place for functional isolationalism, that is, for each department to do their own activities independently. Rather it is an organization in which each part is joined together and concentrating on the same objectives. The hospital must maintain a one-system-function, so that all the resources of the hospital may be used efficiently. Although we do not yet completely understand how the nursing image as perceived by the medical team and the other members of the interdisciplinary team affects nursing practice. It is important to identify how the client recognizes the nursing image as this will influence the growth of the nursing profession directly and indirectly. So we must reevaluate the nursing image as presented to the client and find the ways to present them with a better image of nursing. The study procedures were as follow; First, the image of nurses was analyzed. The subjects for this study were 270 nurses, 172 doctors, 237 hospital employees, and 240 patients and their families from 5 local branches of the Yonsei Medical Center. The four negative responses shown in this study are as follows; 1) Nurses don't listen to patients. 2) Nurses are self-centered. 3) Nurses and careless. 4) Nurses are mechanical. Second, the concrete causes of the four negative responses were analyzed. Third, the contribution of the nurses for clinical practice, research and education was analyzed. Data were collected by questionnaires all seps of the research. Data were analyzed by use of SPSS/PC. In conclusion, the image of nurses differed according to which group, the respondents belonged. Generally, the public have a positive image of nurses, but hospital employees have a negative images of nurses. Further the nurses gave themselves a low grade. They showed negative as to the value of their job, professionality and their contribution to clinical practice when it was compared to that of the doctors.

This study was undertaken to review the relationship between middle-school students' food-behavior and their health conditions/school performances. For this purpose, 495 male and female middle-school students were sampled form seven middle schools located in Seoul for a questionnaire survey. The surveyed data were analysed with simple frequency, percentage, t-test, chi-square test, dispersion analysis, Pearson's correlation and hierarchical multiple-regression analysis which make use of the SPSS/PC+ package system. The results of survey can be summarized as follows; Most of students had three meals a day regularly, but some female students used to skip breakfast or supper. The amount of a mael was adequate. Their main night-smacks were fruits. The problem perceived by students was unbalanced meal ; Female students took more snack than that of male students. They usually took a snack a day. All students tended to take delicious snacks. The most favorate smack of students was fruits. Most students did not suffer any serious diseases, but some had one or more respiratory diseases. Female students had some or other physical troubles in their eyes, mouth, digesting organs, muscle/bone, skin and had fatigue. Female students had mental problems of depression, uneasiness and hostility. The average I.Q. of students was 117.4, and those who had higher I.Q. got much higher scores. The regularity and amount of meal and intake of animal food were all positively related with the growth of height and weight. And the taller, the higher I.Q. they had. Those students who took meals three times regularly and adequately, who had no coffee and snack and who took balanced meals were healthier in both physical and mental terms. In particular, those who had adequate amount of breakfast regularly were not only healthier but also had higher I.Q. and school performance.
