PURPOSE: The purpose of this study was to examine effect of Tai-Chi exercise program on joint flexibility for osteoarthritis patients. To evaluate the effects, quasi-experimental study was used for pre and post test with a nonequivalent control group. METHOD: Fifty-tow subjects participated in the experiment(twenty-seven for experimental group and twenty-five for control group) and they were from two different senior citizen centers in J city. The experiment period was from April 2002 through August 2002. The experiment group took part in Tai-Chi exercise program for eighteen weeks(three times a week for four weeks and five times a week for fourteen week). The exercise was performed for 50 minutes at every time (15 minutes for warm-up, 30 minutes for Tai-Chi exercise, and 5 minutes for ending). In order to pursue study purpose, the SPSS/WIN 8.0 program was chosen for the statistical analysis; ANCOVA was employed in examining test hypothesis; t-test and chi2-test were used to examine homogeneity between experimental and control group. RESULT: The study results were as follows :Score of vertebral joint flexibility increased significantly after of Tai-Chi exercise program. Score of wrist joint extension increased significantly after of Tai-Chi exercise program. Score of wrist joint flexion increased significantly after of Tai-Chi exercise program. Score of elbow joint extension increased significantly after of Tai-Chi exercise program. Score of elbow joint flexion increased significantly after of Tai-Chi exercise program. There was a slight increase of knee joint extension in the Tai-Chi exercise group compared to control group, but without statistical significance. Score of knee joint flexion increased significantly after of Tai-Chi exercise program. Score of ankle plantar flexion increased significantly after of Tai-Chi exercise program. Score of ankle dorsiflexion increased significantly after of Tai-Chi exercise program. CONCLUSION: As shown in the results, Tai-Chi exercise program can be effective nursing intervention for osteoarthritis patient to improve joint flexibility.

PURPOSE: The purpose of this study was to identify the degree of Job stress and Coping of the nurses in ICU and Cancer ward, and to compare the Job stress and Coping between two groups, and finally to get the basic information about the adequate method to promote Coping about Job stress of the nurses in ICU and Cancer ward. METHOD: The subjects of this study were 131; 62 nurses in ICU and 69 nurses in Cancer ward. Data were collected from 27th August to 14th September in 2007. The instruments for this study were Job stress scale(55 items) developed by Kim(1989), and Coping scale(32 items) developed by Lazarus and Folkman(1984) and revised by Han and Oh(1990). For the data analysis, SPSS PC/win 12.0 program was utilized for descriptive statistics, chi2- test, t-test, Pearson correlation. RESULT: The results of this study were the followings; The mean score of Job stress(range 1-5) was 2.93 in ICU nurse and 2.58 in Cancer ward nurse. There was a significant difference (t=4.453, p <.01)between them. There were significant differences in subscale of Job stress between the two groups, such as Nursing job(t=3.717, p <.01), Job circumstances(t=4.558, p <.01), Personal relations(t=3.425, p <.01), Hospital administration and ward management(t=2.94, p <.01). The mean score of Coping(range 1-4) was 2.55 in ICU nurse, and 2.54 in Cancer ward nurse; there was no significant difference. But one subscale of the Coping(Search of social support) showed significant difference(t=-2.865, p <.01). There was no significant correlation between Job stress and Coping of ICU nurse vs Cancer ward nurse except one subscale in cancer ward(correlation between Nursing Job and Coping). CONCLUSION: The ICU nurse is higher than the Cancer ward nurse in the Job stress score significantly and lower than the Cancer unit nurse in the Coping. Based on the study results, it is needed the program development using the Coping methods in accordance with ward speciality to relieve Job stress.

PURPOSE: To evaluate the clinical usefulness of 2-D Cine PC (phase contrast) technique in visualizing the pattern and the site of abnormal CSF flow and to assess the effect of a third ventriculostomy in patients with hydrocephalus. MATERIALS AND METHODS: The study group consisted of three normal controls and 13 patients with hydrocephalus, as shown on CT or MRI, and two patients who had undergone their third ventriculostomy. The technique was EKG-gated 2-D Cine PC MRI with velocity encoding 5cm/sec, TR 80msec, TE 12.3-15msec, and flip angle 15-60 degrees. Image quality was analyzed for variable sequences, and CSF flow was observed along the CSF flow pathway. We analyzed continuity and intensity of the CSF flow signal, and obstruction site and flow velocity degree were then defined. RESULTS: Systolic high and diastolic low signal intensity along the CSF flow-pathway, with normal asynchronicity and continuation, were clearly seen in normal controls. In three patients, there was obstruction at the ventricular level while others were either normal or showed a normal pattern with a weak signal. 'Normal' was defined as noncommunicating hydrocephalus and the latter as communicating hydrocephalus. In the two patients who had undergone ventriculostomy, a signal was in one case detected at the site of the third operation. CONCLUSION: A 2-D Cine PC CSF flow study enables us to see CSF flow signals noninvasively and to detect the site of obstruction of a CSF flow-pathway. It can therefore be useful for determining the application of a ventriculoperitoneal shunt and assessing the effect of a third ventriculostomy.

PURPOSE: To evaluate whether soft tissue surrounding the celiac axis, as seen on abdominal CT imaging after gastrectomy for gastric carcinoma, should be considered as the recurrence of carcinoma or postoperative change. MATERIALS AND METHODS: One hundred and forty-one abdominal CT examinations of 71 patients who had undergone subtotal or total gastrectomy for gastric carcinoma were included in our study. Conventional CT scans were obtained with 1 cm thickness and interval from the diaphragm to the kidneys after contrast enhancement. It was considered that carcinoma had not recurred if findings were negative on UGI series, endoscopy with biopsy and a normal level of carcinoembryonic antigen except for soft tissue surrounding the celiac axis on abdominal CT. We then divided subjects into a recurrence group (N = 20) and normal group (N = 51) and on initial follow-up CT (FU-CT), analyzed the incidence, margin, shape, extent, degree and pattern of attenuation of the soft tissue surrounding the celiac axis in both groups. Since the second FU-CT examination, we observed changes in the soft tissue surrounding the celiac axis. RESULTS: On initial follow-up CT, at mean 308 days after surgery, fifty-five percent(39/71) of total patients (70% (14/20) of the recurrence group and 49% (25/51) of the normal group) showed soft tissue surrounding the celiac axis. The margin was distinct in 12 (86%) of the recurrence group and indistinct in 21 (84%) of the normal group (P < 0.001). Twelve (86%) of the recurrence group showed a nodular or confluent nodular shape and 21 (84%) of the normal group showed a permeative shape (P < 0.001). Extent was unilateral in eight (57%) of the recurrence group and bilateral in 16 (64%) of the normal group. Attenuation was similar to that of the spleen and muscle in seven (50%) of the recurrence group and was similar to that of muscle in 18 (72%) of the normal group. The pattern of attenuation was homogeneous in 13 (93%) of the recurrence group and 21 (84%) of the normal group. There was no significant difference in extent, degree and pattern of attenuation between the two groups. Since the second FU-CT examination, soft tissue surrounding the celiac axis was seen to have changed. In one patient in the recurrence group it had a distinct margin, was nodular in shape, unilateral in extent and showed attenuation similar to that of the spleen. In one patient in the normal group, it had changed and had an indistinct margin, three patients showed a decrease in the amount of soft tissue and eight showed decreased attenuation. CONCLUSION: Follow-up abdominal CT is useful in the differentiation of cancer recurrence and postoperative change, and for observing changes in soft tissue surrounding the celiac axis.

BACKGROUND: Recent technological developments have introduced a new method to identifying M. tuberculosis complex DNA in clinical samples directly. The direct amplification test (DAT) is approved for identifying M. tuberculosis complex in respiratory specimens that are smear-positive for acid-fast bacilli (AFB). When there is a discrepancy between the AFB smear and DAT, no information on their clinical utility is currently available. In this study, the diagnostic reliability of DAT was investigated in suspected pulmonary tuberculosis patients whose sputum AFB smear was negative. METHODS: From June 1, 1998 through May 30, 1999, 909 patients with presumed active pulmonary tuberculosis were enrolled. A sputum AFB stain, culture, DAT and /or biopsy were performed. using the criteria of clinical tuberculosis or confirmed tuberculosis, the positive predictive value of DAT in diagnosing pulmonary tuberculosis was investigated. RESULTS: The positive predictive value of DAT was 82.1% by the clinically active tuberculosis criteria. However, it decreased to 61.5% when diagnosis was restricted to only to culture positive or biopsy proven cases. The false positive rate of DAT was 18.0%. CONCLUSION: The DAT is a valuable diagnostic method in suspected patients whose sputum AFB is was negative.

BACKGROUND: The effects of propofol-rocuronium on the conditions of tracheal intubation, maternal hemodynamic changes and status of neonates were evaluated in 28 parturients undergoing an elective caesarean section. METHODS: Anesthesia was induced with propofol 2 mg/kg and rocuronium 0.6 mg/kg and maintained with O2-N2O-Propofol. Neuromuscular transmission was assessed using the electromyographic response to the train-of-four stimulation of the ulnar nerve at the wrist every 10 s. Intubation was begun at the disappearance of the T3 of the TOF or 80 s from the administration of rocuronium, whichever occurred first. The conditions for tracheal intubation were classified into four grades as excellent, good, poor and inadequate. The time to the T1 disappearance (onset time) and the time to the reappearance of T2 (duration of the effect) were recorded. The maternal arterial blood pressure and heart rates were measured before and after propofol-rocuronium administration. The neonates were evaluated by the 1-5 min Apgar scores and the acid-base status of the umbilical cord blood. RESULTS: The mean intubation time was 74.4 +/- 10.1 s and the onset time of rocuronium was 100.8 +/- 31.8 s. The intubation conditions were excellent or good in 26 patients (93%) but poor in 2 patients. The maternal arterial blood pressure decreased and the heart rate increased after administering the propofol-rocuronium. The neonatal Apgar scores and blood gas parameters were within the normal range. CONCLUSIONS: Rapid sequence intubation using propofol-rocuronium is clinically acceptable as a caesarean section anesthetic.

PURPOSE: To evaluate the usefulness of MRI findings in the differentiation of benign from malignant ovarian lesions. MATERIALS AND METHODS: Using MR findings, 29 surgically proven ovarian masses in 22 patients (14 bilateral tumors) were evaluated Twenty-one benign tumors in 16 patients (5 simple cysts, 4 mucinous cystadenomas, 4 serous cystadenomas, 4 endometriomas, 3 cystic teratomas and 1 tuboovarian abscess), and eight malignant tumors in six patients (4 serous papillary cystadenocarcinomas and 4 mucinous cystadenocarcinomas) were included. MRI was performed with SE T1WI, FSE T2WI and Gd-T1WI. MRI findings of lesion size, thickness of wall and of internal septations, number of internal septations, nodularities, and ancillary findings such as adhesion in the pelvic cavity, dissemination, ascites and lymphadenopathy were retrospectively analyzed. RESULTS: Malignant ovarian lesions were larger (18 cm : 11 cm) and had more internal septations, more solid components and nodularities (63 % : 5 %) than benign lesions. On T1WI, cystic lesions, both benign and malignant, showed low signal intensity. Hemorrhage, fat components and mucin containing lesions showed high signals and solid components and nodularities were isointense with muscle on T1WI. Solid components and nodularities were well-enhanced after gadolinium enhancement. Adhesion (50 % : 10 %), dissemination (38 % : 0 %) and ascites (63 % : 24 %) were more frequent in malignant lesions. CONCLUSION: MRI, especially with gadolinium-enhanced T1W1 is useful in the differentiation of benign from malignant ovarian lesions.

The purposes of this study were to describe systematically 18 years of oncology nursing research in Korea and suggest it's direction in future. 149 nursing studies published from 1980 to 1998 were selected for the present study. There were examined the source and the design of study, type of subjects, measurement variables, the intervention outcome of experimental research, and theme of qualitative research. The results were as follows : 1. 121 of 149 studies were composed of master thesis and dissertation of graduate school. There were 55 correlations, 30 descriptions, 19 comparisons, 19 qualitative studies and 2 Q-methods as the type of research design. 2. Cancer patients without describing specified diagnose as subjects' characteristic were 44 of total studies. The others had various diagnoses such as gastric cancer, uterine cancer, breast cancer, leukemia, Iymphoma, colorectal cancer, and lung cancer. According to treatment type. patients receiving chemotherapy were the highest number distribution as 53 of all researches. 3. Most measurement instruments used for research were translated it into Korean that developed by foreigners, such as Zung's depression. Spielberg's anxiety, and Wallston's locus of control. 4. Quality of life was shown the most frequently among correlational researches. the next one was depression the third was hope, and so on. 5. There was the most frequent comparison between cancer and non-cancer patients in comparative researches. It was surveyed those variables as diet habits, risk factors, stressful life events, anxiety and depression and self-care capacity between two groups. 6. The subjects were mostly chemotherapy Patients as 15 of 24 experimental studies. Oral care and education were respectively the highest experimental interventions. 7. Qualitative researches about cancer were reported since 1991. Their themes were illness experience, adaptation process, dying experience, family experience, hope. caring, experience of health behavior, meaning of chemotherapy and experience of cancer survivor. Phenomenologic methodology was designed above 50% of qualitative researches. According to the above findings, cancer research had increased since 1990 and done mostly by descriptive design but a few experimental studies. As recommendations for the future, It is necessary to study the comparison of oncology nursing research internationally. the replication to establish the effect of nursing intervention and the family care of cancer patient.

PURPOSE: The purpose of this randomized clinical trial is to determine whether implant length and the crown-to-implant (C/I) ratio influence implant stability and peri-implant marginal bone loss (MBL). MATERIALS AND METHODS: 46 patients with single tooth missing in the posterior molar region of the mandible were included in this study. 19 implants (CMI IS-III active® long implant) of 5.0 mm diameter and 10 mm length were installed for the control group, while 27 implants (CMI IS-III active® short implant) of 5.5 mm diameter and 6.6, 7.3 or 8.5 mm length were placed for the experimental group. Each implant was inserted and immediately loaded using the digitally pre-fabricated surgical template and provisional restoration. The CAD-CAM monolithic zirconia crown was fabricated at 3 months after the surgery as a definitive restoration. The ISQ value and the MBL was measured at 48 weeks after the surgery. The correlation between the C/I ratio, MBL, and secondary implant stability was analyzed. RESULTS: Successful results in terms of ISQ and MBL were achieved with both groups. There was no significant difference between the groups in terms of ISQ values and MBL at 48 weeks after the surgery (P > 0.05). No significant correlation was found between the C/I ratio and secondary stability as well as the C/I ratio and the MBL (P > 0.05). CONCLUSION: The influence of C/I ratio in both groups was not shown on the stability nor the marginal bone loss in implants supporting single crown of the mandible. Short implant could be a preferable alternative option in the reduced bone height mandible under the limited condition despite its higher C/I ratio.
