Eighteen Suffolk wether lambs (BW = 24 kg) were chronically exposed to temperatures of cold (2$^{\circ}C$) or warm (22$^{\circ}C$). The experimental design consisted of a 2${\times}$3 factorial with a single crossover of environment treatment. The sheep were closely shorn and were housed in individual metabolic crates in controlled environment rooms. Sheep consumed pelleted diets ad libitum, which consisted of mainly barley grain and brome grass, and diets contained 7, 11 or 14% crude protein (CP). Animals were catheterized via one jugular vein with a PVC catheter and received a single injection of 60-65 Ci of $^{14}$C]urea. Plasma urea-N (PUN), urinary urea (UU), and carbon specific radioactivity were measured. Urea metabolism was not affected by environment. Percent urea recycling and urea space clearance were highest (p<0.05) on the low nitrogen diet. Urea pool was increased (p<0.10) for the 14% CP diet. Both UU and PUN concentration were positively related (p<0.01) with diet CP content. Therefore, dietary CP content significantly influenced urea metabolism, however, cold exposure did not alter those parameters.

The aim of this study was to explore the angiographic diagnosis and embolization therapy for renal artery pseudoaneurysms due to acute urinary tract hemorrhage after conservative medical management failed. Seven out of ten cases had fever symptoms after the kidney surgery. The pseudoaneurysms were treated with gelatin sponge and (or) spring coil and the majority demonstrated rapid blockage of hemorrhage. Angiography diagnosis and trans catheter embolization are rapid, safe and effective methods for diagnosis and treatment of renal artery pseudoaneurysms.

Purpose: To investigate the duration of each nursing activity performed by home care nurses for non-cancer patients and the relationship between patients' palliative prognostic index (PPI) and duration of each nursing activity. Methods: Nursing activities performed for six non-cancer terminal patients were timed using a stopwatch, and 18 parameters were measured by visiting each patient thrice. The mean and standard deviations of duration for each category of nursing activities were computed. The relationship between category-specific duration of nursing activities and PPI was analyzed with Spearman's correlation and multiple regression analysis. Results: Among nursing activities, the highest greatest duration of time was spent on traffic time (11.91 min), followed by urinary catheter management (10.65 min) and insertion and management of nasogastric tube (9.03 min). In terms of nursing categories, after excluding movement time, the greatest duration of time was spent on excretion care (5.48 min), nutrition care (5.40 min), and medication (3.82 min). PPI correlated with hygiene care, excretion care, and patient and information management. Multiple regression analysis revealed that PPI increased with increasing duration of hygiene care. Conclusion: These study findings provide grounds for the increased nursing time of hygiene care for people reaching the end of life.

Recently a non-electronic, disposable and portable infusor(Baxter infusor with patient control module, Baxter health care Co., Deerfield IL 60015 USA: BI $\bar{c}$ PCM) has been developed that will deliver both a continuous drug infusion as well as allow the patient to deliver extra doses of medication on a demand basis under predetermined limitation of analgesics. Patients may also not require as high analgesic dose rate to control pain when the acceptable and tolerable level of pain relief can be maintained by this device. From April l99l, we have used a total l93 units of BI $\bar{c}$ PCM. These units consisting of two components which one made by a balloon reservoir(capacity 65 ml, flow rate 0.5 ml/hr) to store medication and to regulate the pump power(490 torr), and another two PCMs to regulate additional analgesic administration by patients demand at intervals of 1S minutes and 60 minutes. The dose administered to the patient can be varied by changing the concentration of the infusate within the balloon reservoir. These devices were utilized for the pain control of 44 patients. These patients were divided into two groups. Twenty seven cases had cancer pain and 17 cases had non-cancer pain. The Touhy needle(No. l8 G.) tip was inserted into the epidural space and was used to guide the catheter to the spinal nerve level corresponding to the most painful area. The device was connected to the opposite site of the catheter tip and was filled with 60 ml of mixture solution such as 0.5% bupivacaine 15 ml, morphine HCl 10 mg, trazodone 10 ml, Tridol 3 ml and normal saline 31 ml were administed as the initial dose. When the initial dose was less effective, the next dose could be varied by increasing the concentration of bupivacaine, by adding more morphine (5~10 mg), and by reducing the volume of normal saline. Using these modules of drug self administration, we experienced the following: 1) Improvement of patient's self titration of analgesic requirement was provided. 2) The patients anxiety with pain recurrence resulting from delays in administering pain control medication was decreased significantly. 3) The working load accompanying with the single bolus injection as the usual method was reduced remarkably. 4) There was urinary retention in 5 cases and pruritus in 4 eases which developed as side effects but respiratory depression and vomiting was not encountered in a single case.

Objective : The purpose of this prospective study was to evaluate the effects of body mass index (BMI) on intra-abdominal pressure (IAP) and intraoperative blood loss (IBL) during lumbar spinal surgery. Methods : Thirty patients scheduled for single level posterior lumbar interbody fusion were allocated equally to a normal group (Group 1, BMI;$18.5-22.9kg/m^2$), an overweight group (Group 2, BMI; $23-24.9kg/m^2$), and an obese group (Group 3, BMI; $25.0-29.9kg/m^2$) according to BMI. IAP was measured using a urinary bladder catheter; 1) supine after anesthesia induction, 2) prone at skin incision, 3) prone at the end of surgery. In addition, IBL was also measured in the three groups. Results : IAP in the supine position was not significantly different in groups 1, 2, and 3 (2.7 mm Hg, 3.0 mm Hg, and 4.2 mm Hg, respectively) ($p$=0.258), and IAP in the prone position at incision increased to 7.8 mm Hg, 8.2 mm Hg, and 10.4 mm Hg, respectively, in the three groups, and these intergroup differences were significant, especially for Group 3 ($p$=0.000). IAP at the end of surgery was slightly lower (7.0 mm Hg, 7.7 mm Hg, and 9.2 mm Hg, respectively). IBLs were not significantly different between the three groups. However, IBLs were found to increase with IAP in the prone position ($p$=0.022) and BMI ($p$<0.05). Conclusion : These results show that BMI affects IAP in the prone position more than in the supine position during lumbar spinal surgery. In addition, IBLs were found to increase with IAP in the prone position and with BMI. Thus, IBLs can be expected to be higher in morbidly obese patients due to an increased IAP.

Purpose: This study was done to examine current status of women's health nursing practicum and identify necessary core nursing skills in this practicum area. Moreover, one syllabus and evaluation sheets for women's health nursing clinical practicum at one university were reviewed. Methods: A survey design was used with 81 educators who were teaching maternity or women's health nursing and its practicum. Results: Most clinical sites for practicum were university hospitals (43.0%), women's hospitals (32.7%), or general hospitals (17.3%); but the majority (77.8%) of educators expressed difficulty in finding appropriate practicum places. Common teaching and learning methods were clinical guides for practicum (44.6%), e-learning content (30.2%), and simulation (23.6%). Core nursing skills for this practicum included assessment of stages of labor, preparation of uterine-fetal monitoring devices and interpretation of results, monitoring uterus and fetal activity, and performing Leopold's maneuver. For postpartum care, the following were included; postpartum fundal massage, assessment of breast engorgement, fundus height, and episiotomy sites, inserting urinary catheter, and teaching the use of patient-controlled analgesia. Conclusion: To improve the quality of clinical practicum, development of a clear course syllabus, standardized clinical guidebook, and core nursing skills is required and should be shared with all relevant nurse educators.

Postoperative hypoxemia in the absence of hypoventilation occurs more often after thoracic or upper abdominal surgery than lower abdominal operations or surgery on extremities. Although the factors which produce postoperative alveolar collapse have not been fully evaluated, the dominant factor of postoperative hypoxia is shunt of blood passing collapsed alveoli and the postoperative pain is associated with restriction of depth of breathing, sighing and movement. In 1979, the first successful clinical usage of epidurally administered morphine was done by Behar and associates for control of postoperative pain. This study was carried out for twenty patients who received posterolateral thoracostomy with Bled resection between May 1990 and May 1991 and who were primary spontaneous recurrent pneumothoraxes. We selected ten of twenty patients, one after the other and treated with epidural analgesia as study group and the remainder ten were grouped as control. Epidural catheters were inserted for study group before operation through T12-L1, 2 interspinous process at the pain clinic or operation room by anesthesiogist and then the drugs[0.25% Bupivacaine 15ml mixing with morphine 3mg] were instillated through the catheter before extubarion and once a day until 4th day, and the patients of control group were treated intermittently by Demerol 50mg intramuscularly for postoperative pain control. The epidural catheters were removed at postoperative 4th day. Observations were done about vital aigns, a-BGA, tidal volume, FVC and occurence of adverse effects during postoperative 2hr, 8hr, 1st day, 2nd day, 7th day in both groups. The results were as follows; [1] Tidal volume[85.1$\pm$29.8%R VS 60.8$\pm$20.5%R, p<0.05] and FVC[53.7$\pm$14.2%R, VS 35.5$\pm$9.l%R, p<0.01] were significantly improved in study group compared with control group during the first day of operation. [2] But the improvement of FVC was delayed after stopping of epidural analgesia[postoperative 7th day, 97.5$\pm$12.3%R VS 83.9$\pm$15.6%R, P <0.05]. [3] Others were statistically not significant. [4] The side effects of epidural analgesia were identified such as urinary retention[2 cases], itching sensation[1 case] and headache[1 case], but there was no need for active treatments.

본 연구의 목적은 낮은 전단흐름조건에서 편모 운동성이 박테리아의 거동 특성에 미치는 영향을 파악하는데 있다. 대다수의 미생물은 편모를 이용하여 수용액 내에서 운동할 수 있는 능력을 가지고 있으며, 이러한 운동성은 수계나 수처리 시스템에서 미생물의 거동에 있어서 중요한 역할을 한다. 그러나 현재까지 병원성 미생물의 이동 현상과 관련된 연구에서 편모에 의한 운동성은 거의 고려되지 않고 있는 실정이다. 본 연구에서는 미세유체장치를 이용하여 전단흐름이 낮은 조건에서 E. coli의 거동 특성을 파악하고자 하였다. 실험을 통하여 유속이 작은 경우에 E. coli는 포물선의 형태의 궤적들을 그리며 이동하는 것을 알 수 있었으며, 벽면 근처에서는 상류로 헤엄쳐 올라간다는 것을 파악하였다. 또한 유속과 종횡비(aspect ratio)에 따른 궤적의 변화를 분석하였는데, 유속이 작을수록 포물선 형태의 궤적을 그리게 되며, 길이가 짧을수록 보다 작은 회전 반경을 그리며 운동하는 것을 관찰할 수 있었다.
