Purpose: The purpose of the study was done to identify the nursing care needs of patients in the recovery room. Method: The subjects in this study were 127 patients in a recovery room between 6/9/2001 and 24/9/2001. The instrument used for this study was the descriptive questionnaire developed by Shin Hyun-Jin (1999). The data was analysed by frequency, percentage, mean, standard deviation, t-test, ANOVA, and factor analysis using the SPSS program. Result: 1) Kaiser - Meyer -O1kin sample appropriateness was 799 and Bartlett's test of sphericity significant probability was .000. 2) The mean score for nursing care need of patients in the recovery room was $4.17{\pm}.51$ of a total possible score of 5. The score of nursing need for different parameters was as follows : Educational need ($4.31{\pm}.49$), physical need ($4.27{\pm}.47$), emotional need ($4.11{\pm}.52$), environmental need ($3.99{\pm}.56$). 3) Differences in the needs for nursing care according to the demographics were significant for gender, marital status, operation experience, and departments consulted. General characteristic variables significantly related to nursing need were as follows: Physical need significantly related to the departments consulted (F=2.23, p=.036). Educational need significantly related to the marital status (F=2.55. p=.012), departments consulted (F=2.30, p= 031). Emotional need significantly related to the marital status (F=2.22, p=.028). Environmental need significantly related to the gender (t=-2.44, p= .016), marital status (F=2.01, p= .046). operation experience (t=-1.99. p= .048). Conclusion: Nursing care needs of patients in the recovery room are significantly related to educational need, physical need, emotional need and environmental need. Intervention plans and program need to be developed to improve strategies to meet nursing needs of patients in the recovery room.

Postoperative pain is one of the most frequently occurred pain in hospitals, but it has been underestimated because it is only a part of postoperative physiological Process and may disappear in time. It is necessary that nurses me the relaxation technique, planning and implementing by themselves independently, to reduce this postoperative pain. This study is aimed at showing the effect of relaxation technique on reduction of postoperative pain, and exploring the factors influencing postoperative. pain Fifty-seven patients with abdominal surgery who admitted in attacked D Medical Center to K University in Daegu have been studied. Of them twenty-nine were experimental group and the remaining twenty-eight were control group. This study has been conducted for collecting data through interviews and observation from August 23 to October 24, 1984. The tools of this study were two kinds: Postoperative Pain Scale is obtained from a review of references by the researcher, and relaxation technique, designed to use postoperative setting adequately, is also obtained from a review of references by the researcher. After confiriming no significant differences between the two groups, the hypotheses were statistically verified by x²-test, t-test, and pearson Correlation Coefficient. The results of this study are summerized as follows; ＊ The nam hypothesis that the experimental group who use relaxation technique will have less degree of postoperative pain than the control group who don't use relaxation technique is devided into three sub-hypotheses. 1. The first sub-hypothesis that the experimental group will have less score of postoperative pain than control group was accepted (t=7.810, p <.01). Even with controlling pain threshold, showing difference in some degree between the two groups, the experimental group has less score of postoperative pain than the control group. Therefore this confirms the acceptance of the first sub-hypothesis more strongly. 2. The second sub-hypothesis that the expermental group will have less frequency of analgesics than the control group is accepted (x²=9.85, p <.01). 3. The third sub-hypothesis that the experimental group will have less variation of pulse, respiration, and blood pressure between pre End post operative periods than the control group is rejected. So this hypothesis is reverified through comparing the variation of pulse, respiration, and blood pressure between pre and post changing Position to measure the pure effect of relaxation technique. pulse and respiration is significantly lowered in the experimental group (t=7.209, p<.01, t=3.473, p<.01), but systolic and diastolic blood pressure is not different significantly between the two groups (t= 1.309, p＞.05, t=1. 727 p>.05). Therefore the third sub-hypothesis is partially accepted. Conclusively, the researcher thinks that it is necessary that nurses should provide patients with relaxation technique to reduce postoperative pain, and to increase independence of nursing.

Geant4 (GEometry ANd Tracking) provides various packages specialized in modeling electromagnetic interactions. The validation of Geant4 physics models is a significant issue for the applications of Geant4 based simulation in medical physics. The purpose of this study is to evaluate accuracy of Geant4 electromagnetic physics for proton therapy. The validation was performed both the Continuous slowing down approximation (CSDA) range and the stopping power. In each test, the reliability of the electromagnetic models in a selected group of materials was evaluated such as water, bone, adipose tissue and various atomic elements. Results of Geant4 simulation were compared with the National Institute of Standards and Technology (NIST) reference data. As results of comparison about water, bone and adipose tissue, average percent difference of CSDA range were presented 1.0%, 1.4% and 1.4%, respectively. Average percent difference of stopping power were presented 0.7%, 1.0% and 1.3%, respectively. The data were analyzed through the kolmogorov-smirnov Goodness-of-Fit statistical analysis test. All the results from electromagnetic models showed a good agreement with the reference data, where all the corresponding p-values are higher than the confidence level $\alpha=0.05$ set.

Objectives : To evaluate the safety of multiple-dose intramuscular Shinbaro Pharmacopuncture in male and female Sprague-Dawley(SD) rats over a period of 4 weeks(12 sessions). Methods : In order to test the safety of multiple-dose intramuscular Shinbaro Pharmacopuncture we used 40 healthy male and female 6-week old SD rats(male weight 171.79~196.37 g, female weight 127.93~146.43 g). Shinbaro Pharmacopuncture was administered intramuscularly to male and female SD rats at doses of 4.6 (low dose group, n=10), 9.2 (moderate dose group, n=10), and 18.5 mg/kg(high dose group, n=10), respectively. General symptoms, body weight changes, blood tests, biochemical testing, necropsy, organ weight and histopathogical findings were examined over a 4-week period. Results : 1. No mortalities or adverse effects were caused by the investigational substance were observed during the study period. 2. There was no significant difference in body weight caused by the the investigational substance across all groups. 3. No significant between-group difference was found to be caused by the investigational substance in blood tests and biochemical testing. 4. No abnormalities were detected by a necropsy examination with the unaided eye at the macro level after treatment with the investigational substance. 5. Difference in organ weight between groups caused by the investigational substance was not found. 6. All groups did not exhibit pathological findings caused by the investigational substance in histopathogical examination. Conclusions : According to these results, Shinbaro Pharmacopuncture has no systemic or organ toxicity with multiple-dose intramuscular administrations in male and female SD rats over a 4-week period (12 sessions). These results imply that no adverse effects are observed at a level (NOAEL) of Shinbaro Pharmacopuncture of 18.5 mg/kg.

Temperature lapse rate within the planetary boundary layer shows a diurnal cycle with a substantial variation. The widely-used lapse rate value for the standard atmosphere may result in unaffordable errors if used in interpolating hourly temperature in complex terrain. We propose a simple method for estimating hourly lapse rate and evaluate whether this scheme is better than the conventional method using the standard lapse rate. A standard curve for lapse rate based on the diurnal course of temperature was drawn using upper air temperature for 1000hPa and 925hPa standard pressure levels. It was modulated by the hourly sky condition (amount of clouds). In order to test the reliability of this method, hourly lapse rates for the 500-600m layer over Daegwallyeong site were estimated by this method and compared with the measured values by an ultrasonic temperature profiler. Results showed the mean error $-0.0001^{\circ}C/m$ and the root mean square error $0.0024^{\circ}C/m$ for this vertical profile experiment. An additional experiment was carried out to test if this method is applicable for the mountain slope lapse rate. Hourly lapse rates for the 313-401m slope range in a complex watershed ('Hadong Watermark 2') were estimated by this method and compared with the observations. We found this method useful in describing diurnal cycle and variation of the mountain slope lapse rate over a complex terrain despite larger error compared with the vertical profile experiment.

Recently, the steel has been increaseingly used as an integrated part of high-rise buildings, which often composed of steel structures, steel reinforced concrete structures and composite structures. The steel base is designed to transfer the stresses induced from steel column to the reinforced concrete footing through the base plate. However, in the design of steel structures and steel reinforced concrete structure, it is generally difficult to evaluate the bearing strength of the steel base subjected to large axial force. Furthermore, the material used in steel base is quite different from those used in other connections and a load transferring mechanism of steel base is very complicated in nature. Therefore, a special attention must be placed in design and construction of steel base. In generally, the bearing strength test and research of the steel base subjected to concentrated load are carried out. But, in the design of the structures, uniaxial eccentric load is loaded to the steel base of the steel structures. In this research, the bearing strength and the me of failure considering eccentric loads and eccentric length, were experimented when eccentric load is loaded to the steel base of steel structures. Based on the test results, a basic design reference is suggested for a reasonable design of steel structures, steel reinforced concrete structures and composite structures.

Carbapenem resistance, mediated by the major acquired metallo-β-lactamase (MBL) genes, has been increasingly reported, particularly for clinical isolates of Acinetobacter spp. Of the 191 nonduplicate clinical isolates of the carbapenem-nonsusceptible Acinetobacter spp. evaluated, 125 isolates (65.4%) were positive for the modified imipenem or meropenem-Hodge test, and 49 isolates (25.7%) were positive for the imipenem-EDTA+SMA double disk synergy test (DDS). PCR and sequencing of the bla_VIM-2-allele and bla_IMP-1-allele showed that 29 A. baumannii isolates and 1 A. calcoaceticus isolate had bla_VIM-2, whereas 16 A. baumannii isolates and 2 A. calcoaceticus isolates had bla_IMP-6; 1 isolate of the A. genomospecies 3 had bla_VIM-2 and bla_AIM-1. All the above MBL genes belong to class 1 integron. The size of class 1 integron encompassing bla_VIM-2 or bla_IMP-6 ranges from 2.8 kb to 3.2 kb in clinical isolates of A. baumannii, and 3.2 kb to 3.5 kb in clinical isolates of A. genomospecies 3. bla_VIM-2 was most often located first or second in the class 1 integron, and these integrons often included aacA4. Due to dispersion of the MBL-producing Acinetobacter spp. as well as integron, which may encompass various resistance genes, there is an expectation for the increase of multidrug resistant Gram-negative bacteria, including resistance of carbapenems such as imipenem or meropenem. Hence, the development of new antimicrobial agents for treating severe Acinetobacter spp. infections is needed.

This study was conducted to investigate the superoxide dismutase (SOD) characteristics and antioxidant activity by nonenzymatic(Fe$^{2+}$/Ascorbate) and Fe$^{3+}$-ADP/NADPH method in perilla(Perilla frutescens var. japonica Hara.) and jaso(Perilla frutescens Briton var. acuta Kudo.) leaves. The characteristics were evaluated by the nitro blue tetrazolium reduction method. Perilla leaves contained three or four major SODs depending on the varieties. The inhibitor test indicated that the Perilla leaves contained two Cu /ZnSODs and one or two FeSODs, but Jaso leaves have only Cu/ZnSOD. However, no varietal differences were detected in the Cu /ZnSOD isozyme patterns. FeSODs, however, showed different varietal isozyme patterns through the different combinations of the two FeSOD isozymes. Among MeOH extractes, "mil yang 2" showed very strong antioxidant activity. Relatively large differences in the levels of SOD and antioxidant activity detected in the Perilla varietites. There was significantly different in the comparison between perilla leaves and red jaso leaves.s.etween perilla leaves and red jaso leaves.
