This study was conducted to derive an Instantaneous Unit Hydrograph for the accurate and reliable unitgraph which can be used to the estimation and control of flood for the development of agricultural water resources and rational design of hydraulic structures. Eight small watersheds were selected as studying basins from Han, Geum, Nakdong, Yeongsan and Inchon River systems which may be considered as a main river systems in Korea. The area of small watersheds are within the range of 85 to 470$\textrm{km}^2$. It is to derive an accurate Instantaneous Unit Hydrograph under the condition of having a short duration of heavy rain and uniform rainfall intensity with the basic and reliable data of rainfall records, pluviographs, records of river stages and of the main river systems mentioned above. Investigation was carried out for the relations between measurable unitgraph and watershed characteristics such as watershed area, A, river length L, and centroid distance of the watershed area, Lca. Especially, this study laid emphasis on the derivation and application of Instantaneous Unit Hydrograph (IUH) by applying Nash's conceptual model and by using an electronic computer. I U H by Nash's conceptual model and I U H by flood routing which can be applied to the ungaged small watersheds were derived and compared with each other to the observed unitgraph. 1 U H for each small watersheds can be solved by using an electronic computer. The results summarized for these studies are as follows; 1. Distribution of uniform rainfall intensity appears in the analysis for the temporal rainfall pattern of selected heavy rainfall event. 2. Mean value of recession constants, Kl, is 0.931 in all watersheds observed. 3. Time to peak discharge, Tp, occurs at the position of 0.02 Tb, base length of hlrdrograph with an indication of lower value than that in larger watersheds. 4. Peak discharge, Qp, in relation to the watershed area, A, and effective rainfall, R, is found to be {{{{ { Q}_{ p} = { 0.895} over { { A}^{0.145 } } }}}} AR having high significance of correlation coefficient, 0.927, between peak discharge, Qp, and effective rainfall, R. Design chart for the peak discharge (refer to Fig. 15) with watershed area and effective rainfall was established by the author. 5. The mean slopes of main streams within the range of 1.46 meters per kilometer to 13.6 meter per kilometer. These indicate higher slopes in the small watersheds than those in larger watersheds. Lengths of main streams are within the range of 9.4 kilometer to 41.75 kilometer, which can be regarded as a short distance. It is remarkable thing that the time of flood concentration was more rapid in the small watersheds than that in the other larger watersheds. 6. Length of main stream, L, in relation to the watershed area, A, is found to be L=2.044A0.48 having a high significance of correlation coefficient, 0.968. 7. Watershed lag, Lg, in hrs in relation to the watershed area, A, and length of main stream, L, was derived as Lg=3.228 A0.904 L-1.293 with a high significance. On the other hand, It was found that watershed lag, Lg, could also be expressed as {{{{Lg=0.247 { ( { LLca} over { SQRT { S} } )}^{ 0.604} }}}} in connection with the product of main stream length and the centroid length of the basin of the watershed area, LLca which could be expressed as a measure of the shape and the size of the watershed with the slopes except watershed area, A. But the latter showed a lower correlation than that of the former in the significance test. Therefore, it can be concluded that watershed lag, Lg, is more closely related with the such watersheds characteristics as watershed area and length of main stream in the small watersheds. Empirical formula for the peak discharge per unit area, qp, ㎥/sec/$\textrm{km}^2$, was derived as qp=10-0.389-0.0424Lg with a high significance, r=0.91. This indicates that the peak discharge per unit area of the unitgraph is in inverse proportion to the watershed lag time. 8. The base length of the unitgraph, Tb, in connection with the watershed lag, Lg, was extra.essed as {{{{ { T}_{ b} =1.14+0.564( { Lg} over {24 } )}}}} which has defined with a high significance. 9. For the derivation of IUH by applying linear conceptual model, the storage constant, K, with the length of main stream, L, and slopes, S, was adopted as {{{{K=0.1197( {L } over { SQRT {S } } )}}}} with a highly significant correlation coefficient, 0.90. Gamma function argument, N, derived with such watershed characteristics as watershed area, A, river length, L, centroid distance of the basin of the watershed area, Lca, and slopes, S, was found to be N=49.2 A1.481L-2.202 Lca-1.297 S-0.112 with a high significance having the F value, 4.83, through analysis of variance. 10. According to the linear conceptual model, Formular established in relation to the time distribution, Peak discharge and time to peak discharge for instantaneous Unit Hydrograph when unit effective rainfall of unitgraph and dimension of watershed area are applied as 10mm, and $\textrm{km}^2$ respectively are as follows; Time distribution of IUH {{{{u(0, t)= { 2.78A} over {K GAMMA (N) } { e}^{-t/k } { (t.K)}^{N-1 } }}}} (㎥/sec) Peak discharge of IUH {{{{ {u(0, t) }_{max } = { 2.78A} over {K GAMMA (N) } { e}^{-(N-1) } { (N-1)}^{N-1 } }}}} (㎥/sec) Time to peak discharge of IUH tp=(N-1)K (hrs) 11. Through mathematical analysis in the recession curve of Hydrograph, It was confirmed that empirical formula of Gamma function argument, N, had connection with recession constant, Kl, peak discharge, QP, and time to peak discharge, tp, as {{{{{ K'} over { { t}_{ p} } = { 1} over {N-1 } - { ln { t} over { { t}_{p } } } over {ln { Q} over { { Q}_{p } } } }}}} where {{{{K'= { 1} over { { lnK}_{1 } } }}}} 12. Linking the two, empirical formulars for storage constant, K, and Gamma function argument, N, into closer relations with each other, derivation of unit hydrograph for the ungaged small watersheds can be established by having formulars for the time distribution and peak discharge of IUH as follows. Time distribution of IUH u(0, t)=23.2 A L-1S1/2 F(N, K, t) (㎥/sec) where {{{{F(N, K, t)= { { e}^{-t/k } { (t/K)}^{N-1 } } over { GAMMA (N) } }}}} Peak discharge of IUH) u(0, t)max=23.2 A L-1S1/2 F(N) (㎥/sec) where {{{{F(N)= { { e}^{-(N-1) } { (N-1)}^{N-1 } } over { GAMMA (N) } }}}} 13. The base length of the Time-Area Diagram for the IUH was given by {{{{C=0.778 { ( { LLca} over { SQRT { S} } )}^{0.423 } }}}} with correlation coefficient, 0.85, which has an indication of the relations to the length of main stream, L, centroid distance of the basin of the watershed area, Lca, and slopes, S. 14. Relative errors in the peak discharge of the IUH by using linear conceptual model and IUH by routing showed to be 2.5 and 16.9 percent respectively to the peak of observed unitgraph. Therefore, it confirmed that the accuracy of IUH using linear conceptual model was approaching more closely to the observed unitgraph than that of the flood routing in the small watersheds.

Capillary blood sampling on the forearm reduces pain caused by skin puncture. The present study compared the blood glucose test results performed at different sampling sites of the forearm, finger, and vein to evaluate clinical validity of this alternative site blood sampling technique. Subjects numbered 555 including 61 diabetic patients participated to measure the glucose concentration on the finger ($G_F$) and the forearm ($G_A$) with a portable glucometer under overnight fasting state. Then, the venous glucose concentration ($G_V$) was measured in 514 subjects in less than 1 hour. The test results were analyzed by simple linear regression, intraclass correlation, and Passing-Bablok regression techniques. $G_A$ was highly correlated with $G_F$ or $G_V$ showing the correlation coefficients (r) of approximately 0.97 (P<0.0001) in the normal group. The patient group also resulted similarly high correlation with only slightly lower r value. The mean differences in glucose concentration were less than ${\pm}10mg/dL$ regardless of the sampling sites. Intraclass correlation coefficients were slightly smaller than r but very much similar in value in both groups. The 95% confidence intervals of the slope as well as the intercept in the Passing-Bablok regression analysis were < ${\pm}20%$ and < ${\pm}20mg/dL$, respectively, which were within the clinically acceptable ranges. These three statistical techniques introduced in the present study well demonstrated the consistency of $G_A$ with $G_F$ and $G_V$. Therefore, the forearm blood glucose test could be considered as clinically valid under fasting condition.

This study is a descriptive study to provide basic data related to types of uniforms worn by nurses. Nurses, other medical center personnel, patients and their famillies were asked for their opinion on changing nurses’ uniforms and how the image of nurses is 1 elated to the type of uniform worn by the nurses. The data for this study were collected during the period from Feb. 25, 1993 to Mar. 26, 1993 at Y-University Medical Center from 132 nurses, 137 other medical center personnel, 117 patients and their families. The instruments used for this study were the Nurses’ Image Scale(NIS) developed by Bown(1986), and an instrument to measure opinions of uniform and cap using photographs of nurses’ uniforms that was developed by the researcher through a literture review. Data were analyzed using the SPPS / PC package, Statistics used for analysis were frequencies, percentages, paired t -test, and oneway ANOVA The results of this study are summarized as follows ; 1. Of the nurses, 84.3%, along with, 51.5% of the medical center personnel, 39.1% of the patients and their families agreed to a change in the color of nurses uniforms. 2. Similarly, 87.4% of the nurses,27.7% of the medical center personnel, 19.3% of the patients and their families were in favor of nurses not wearing caps. 3. Only 11.8% of nurses answered that a white uniform was important to the professional image of nursing. Only 2.4% of the nurses answered that a cap was very important to the professional image of nursing. 4. Only 1.6% of the nurses answered that a white uniform and cap were important to show the role of nurses in the twenty first century. 5. About 1/3, 36.5%, of the medical center personnel, the patient and their families answered that changing the color of the nurses' uniform will make a change in the image of nurses. 6. A White uniform and cap were seen as being im-portant in distinguishing nurses from other medical personnel in the hospital by 76.5% of the medical personnel, the patients and their families. 7. Nurses gave high marks to the idea of no cap regardless of the color of the uniform which would still portray the symbol of the nurses’ role, identity and would differentiate the role from other jobs. The patients and their families gave high marks to a white uniform with cap. 8. Generally, nurses, medical center personnel and patients and their families thought that a colored uniform with cap presented a good image of nurses. 9. There was a significant difference in the response among the three groups(F=24.65, P〈.001) to the figure in a white uniform with a cap, and the patients and their families thought it was the best portrayal of the image of nurses. There was a significant difference among the three groups(F=9.03, P〈.001) to the figure in a white uniform with no cap and the nurses indicated that it was the beat portrayed of the image of nurses. There was no significant difference among the three groups to the figure in a colored uniform with cap. There was a significant difference(F=17.50, P〈. 001) to the figure in a colored uniform with no cap, and the nurses indicated that it was the best portrayal of the image of nurses. In summary, the nurses wanted to change the color of uniform and not to wear a cap. But many of the medical center personnel, patients and their families indicated they did not agree with this idea. Therefore, changing the type of uniform worn by nurses should be done only after consideration has been given to the relation of the change to the professional role of nurses and the image of nurses held people in general. Suggestions arising from this study are as follows : 1. The relation between the role of nurses and their uniform was surveyed, and these results can be used as data when considering a change in uniforms. 2. A change in uniforms should be tried based on the norm established about uniforms. 3. The nurses did not want to wear a cap, but before a decision is definitely made it is necessary to study the philosophy related to the symbol of the cap because the figure of a nurse with a cap portrayed a positive image of the nurses. If the cap is kept, the symbol of the cap should be redefined. 4. In this study, only the image related to the uniform was examined, but in future studies it will be necessary to examine the practicality of various types of uniforms.

Rheumatoid arthritis is a chronic systematic disease with unpredictable course of exacerbation and remission, characterized by pain, joint deformity and reduced activity by joint limitation. The growing public awareness of the need for health management of chronic illnesses, provides impetus for nursing to demonstrate social effectiveness by active nursing intervention in this vast area in general, and with rheumatoid condition in particular. However, nursing interventions to date have not demonstrated its active participation in the management of chronic conditions. Nursing intervention for the patients having rheumatoid arthritis is one such area that needs to be studied intensively and to demonstrate their effectiveness empirically. The purposes of this study were two fold : first, to develop a comprehensive program that was intensified with therapeutic joint exercises in water, self-help group activities and utilization of self-efficacy promoting strategies : and secondly, to determine the effect of aquatic exercise program on pain, physiological changes and quality of life in the rheumatoid arthritis patients. Thirty five female subjects participating in this study were selected from outpatients in the Rheumatism Center, Hanyang University hospital. The period of data collection was from December, 1992 to March, 1993 in seoul and Taejeon. Subjects in Taejeon were assigned to the experimental group. The comprehensive aquatic exercise program for the experimental group was carried out three times a week for 6 weeks in regular swimming pool. Subjects in Seoul did not participated in the program, and treated as the control group. Data were analyzed with repeated measure MANCOVA, t-test, ANCOVA, percentage of change, Kruskal-Wallis 1-Way ANOVA using SPSS $PC^+$ program. Results were obtained as follows : 1) Scores on Korean pain scale, Numeric pain score, and RAI score of the experimental group were significantly lower than those of the control group (t=2.11, p=0.022 ; F=4.40, p=0.044 : t=3.10, p=0.002). 2) There was significant improvement in the physiological parameters (higher joint movement parameters, F=15.64, p=0.024 ; higher lean body mass, percentage of change=+12.2, lower body weight, t=1.01, p=0.026 : lower ESR, t=1.69, p=0.001) in the experimental group compaired with subjects In the control group. 3) There was significant improvement in the specific self-efficacy score through the comprehensive aquatic exercise program(t=2.73, p=0.011), but not in the general self- efficacy score(t=0.62, p=0.113). 4) The quality of life failed to show significant improvement in the experimental group as compaired with the control group (F=3.69, p=0.064). 5) In the experimental group, findings from additional analysis showed no significant difference in the specific self-efficacy between those who continued to aquatic exercise after completing 6 week program and those who stopped (X2=0.086, p=0.690). Therefore, adherence to aquatic exercise program for 6 weeks seem to be affected mainly by self-help group activities. An indepth study to delve into articulation of mechanisms affecting the effect of aquatic exercise program be recommended. A further study is necessary to determine the difference in the effect of group and individual aquatic exercise program, to assess factors affecting adherence to exercise for an extended length of time.

Purpose: Objectives of this study was to investigate the level of anxiety and depression according to the stages of autologous and allogeneic hematopoietic stem cell transplantation (HSCT). It would be provide the basis for effective psycho-emotional nursing intervention. Methods: We report on 52 patients, including 19 with autologous HSCT, and 33 with allogeneic HSCT from August 2002 to August 2003, at a university hospital. Spielberger's State-Trait Anxiety Inventory and Jung's Depression Inventory were used to measure levels of anxiety and depression, respectively, at admission time, the day before HSCT, and discharge time. Data was analyzed using SAS program that included Chi-square test, Fisher's exact test, repeated measures ANOVA and Stepwise multiple regression analysis. Results: In all stages of HSCT, the level of anxiety of patients who underwent allogeneic HSCT was significantly higher than that of autologous HSCT (P=0.047). The depression at the day before HSCT was significantly higher than that at admission. The major variable affecting anxiety in autologous HSCT was depression. Specially depression and gender were significant predictors to explain anxiety in allogeneic HSCT at admission time (61%). Experience of relapse and gender were significant predictors to explain anxiety in allogeneic HSCT at discharge time (36%). Conclusion: We recommend that the anxiety and depression be researched during the stages of allogeneic HSCT, specifically in the day before HSCT. It is necessary to develop an effective psycho-emotional nursing intervention according to the stages of HSCT.

The purpose of this study was to estimate the inbreeding level and effective population size of Korean indigenous chickens. In the study, two variables were considered to evaluate the pedigree completeness: (1) the proportion (%) of animals with complete pedigree, and (2) the proportion of animals with inbreeding coefficients greater than zero. In the proportion of animals having complete pedigree, all strains reached almost 100% completeness in 1~2 years. In the proportion of animals with inbreeding coefficients greater than zero, all strains reached almost 100% completeness in 5~6 years. We considered that the pedigree recoding system is well managed and that the inbreeding coefficient is a reliable measure. Over the past 20 years, the increase of inbreeding coefficients in Korean indigenous chicken strains has been 7.6~10.9%. The S strain showed the most rapid increase of inbreeding coefficient of 8.2% in 10 years. The reason for this rapid increase is considered to be associated with the fact that the numbers of sires and dams involved in reproduction was 115 and 91, respectively, which are lower than those of the other strains. According to average rates of increase in inbreeding coefficients (${\Delta}F$), all strains have ${\Delta}F$ values of 0.39~0.85%, which is lower than 1%, and the effective population size is above 50. The results showed that inbreeding levels were within the acceptable range and that Korean indigenous chicken population scan be regarded as safe from the threat of extinction.

Purpose: For better PET imaging with accuracy the transmission scanning is inevitably required for attenuation correction. The attenuation is affected by condition of acquisition and patient position, consequently quantitative accuracy may be decreased in emission scan imaging. In this paper, the present study aims at providing the measurement for attenuation varying with the positions of the patient's arm in whole body PET/CT, further performing the comparative analysis over its SUV changes. Materials and Methods: NEMA 1994 PET phantom was filled with $^{18}F$-FDG and the concentration ratio of insert cylinder and background water fit to 4:1. Phantom images were acquired through emission scanning for 4min after conducting transmission scanning by using CT. In an attempt to acquire image at the state that the arm of the patient was positioned at the lower of ahead, image was acquired in away that two pieces of Teflon inserts were used additionally by fixing phantoms at both sides of phantom. The acquired imaged at a were reconstructed by applying the iterative reconstruction method (iteration: 2, subset: 28) as well as attenuation correction using the CT, and then VOI was drawn on each image plane so as to measure CT number and SUV and comparatively analyze axial uniformity (A.U=Standard deviation/Average SUV) of PET images. Results: It was found from the above phantom test that, when comparing two cases of whether Teflon insert was fixed or removed, the CT number of cylinder increased from -5.76 HU to 0 HU, while SUV decreased from 24.64 to 24.29 and A.U from 0.064 to 0.052. And the CT number of background water was identified to increase from -6.14 HU to -0.43 HU, whereas SUV decreased from 6.3 to 5.6 and A.U also decreased from 0.12 to 0.10. In addition, as for the patient image, CT number was verified to increase from 53.09 HU to 58.31 HU and SUV decreased from 24.96 to 21.81 when the patient's arm was positioned over the head rather than when it was lowered. Conclusion: When arms up protocol was applied, the SUV of phantom and patient image was decreased by 1.4% and 9.2% respectively. With the present study it was concluded that in case of PET/CT scanning against the whole body of a patient the position of patient's arm was not so much significant. Especially, the scanning under the condition that the arm is raised over to the head gives rise to more probability that the patient is likely to move due to long scanning time that causes the increase of uptake of $^{18}F$-FDG of brown fat at the shoulder part together with increased pain imposing to the shoulder and discomfort to a patient. As regarding consideration all of such factors, it could be rationally drawn that PET/CT scanning could be made with the arm of the subject lowered.

Purpose: The PET of the PET/CT (Positron Emission Tomography/Computed Tomography) quantitatively shows the biological and chemical information of the body, but has limitation of presenting the clear anatomic structure. Thus combining the PET with CT, it is not only possible to offer the higher resolution but also effectively shorten the scanning time and reduce the noises by using CT data in attenuation correction. And because, at the CT scanning, the contrast media makes it easy to determine a exact range of the lesion and distinguish the normal organs, there is a certain increase in the use of it. However, in the case of using the contrast media, it affects semi-quantitative measures of the PET/CT images. In this study, therefore, we will be to establish the reliability of the SUV (Standardized Uptake Value) with CT data correction so that it can help more accurate diagnosis. Materials and Methods: In this experiment, a total of 30 people are targeted - age range: from 27 to 72, average age : 49.6 - and DSTe (General Electric Healthcare, Milwaukee, MI, USA) is used for equipment. $^{18}F$- FDG 370~555 MBq is injected into the subjects depending on their weight and, after about 60 minutes of their stable position, a whole-body scan is taken. The CT scan is set to 140 kV and 210 mA, and the injected amount of the contrast media is 2 cc per 1 kg of the patients' weight. With the raw data from the scan, we obtain a image showing the effect of the contrast media through the attenuation correction by both of the corrected and uncorrected CT data. Then we mark out ROI (Region of Interest) in each area to measure SUV and analyze the difference. Results: According to the analysis, the SUV is decreased in the liver and heart which have more bloodstream than the others, because of the contrast media correction. On the other hand, there is no difference in the lungs. Conclusions: Whereas the CT scan images with the contrast media from the PET/CT increase the contrast of the targeted region for the test so that it can improve efficiency of diagnosis, there occurred an increase of SUV, a semi-quantitative analytical method. In this research, we measure the variation of SUV through the correction of the influence of contrast media and compare the differences. As we revise the SUV which is increasing in the image with attenuation correction by using contrast media, we can expect anatomical images of high-resolution. Furthermore, it is considered that through this trusted semi-quantitative method, it will definitely enhance the diagnostic value.

This study is aimed to evaluate the effects of the educational program that is designed to help the patients of T.K.R.A. to improve their self-nursing ability. The research will show how well this program can contribute to raising of their adaptability of everyday life by decreasing the difficulties that the patients had before in their daily life. The sample persons for this research were 40 adult patients who had T.K.R.A. in our hospital, and the data were collected through the questionnaires which were given to them. For the surveying tool, Jette's scale was applied to measure the degree of uncomforting that the patients experienced in their daily life. The materials of report had been gathered from May 1st to December 10th. The collected data were analyzed with real numbers, percentage, average, the standard deviation, TorF test and Pearsons correlation. The results of this study can be summarized like follows: The survey of self-caring exercise part were processed with two groups containing experiment group and contrast group. The exercise which took the highest points in experiment group was repetition of stretching and bending knees with laid down position while taking a walk, repetition of stretching and bending knees with seated on chair position and repetition of stretching and bending knees with laid down position got high points in contrast group. There were distinctive differences in statistics between repetition of stretching and bending knees in laid down position and taking a walk. There was no significant statistical gap between the degrees of inconveniences of daily life that each two groups experienced when we compared the average of the two groups, but 12 out of 20 questions got considerable differences. According to common characters of self-caring, there was a distinctive gap in the group who left the hospital in 14days and the ones who spend more than 30 minutes with exercise. The patient group who left the hospital in fourteen days after T.K.R.A. spent more time doing self-caring exercise. In the relationship between common characters and the degree of difficulties of daily life, Exercising is effective and Spending more that 30 minutes for exercise showed visible differences. The patients who answered that exercise are effective and put more time for it experienced less pain in their everyday life. The data proved by Pearson's correlation showed the relationship between self- caring and the degree of pain of daily life. According to the result, the increasing of self-caring activities helped to down the degree of inconveniences of daily life. This data show that T.K.R.A. reduced self-caring exercise ability and daily life activities. Therefore, the medical staffs who would take care the T.K.R.A. patients should offer stable nursing through well scheduled and education materials for patients. It is also important to encourage the patients to participate to the exercise by showing them how exercise after T.K.R.A. The education program is expecting to guarantee not only the right of patients to get enough information but also effective result to decrease uncomfortable of daily life.

This study determined the effects of the height and the quality of the material of popular heel-up insole on mean plantar foot pressure during walking. Seven healthy college students who are studying at S university in Busan were as participants in this study. After sufficiently explaining about the research to the subjects before the experiment, mean plantar foot pressures were examined using F-Scan Pressure Measure System 5.23 for the gait with shoes inserted insole and the data were compared among the height and the quality of material of insoles. In the result, there was a difference significantly in the mean plantar foot pressure followed the height of insoles both left and right. Especially, mean plantar foot pressure in left indicated significantly lower in 3 cm and 5 cm insoles than in 0 cm and 1 cm insoles. Also mean plantar foot pressure in right showed significantly lower in 3 cm and 5 cm insoles than in 0 cm, and indicated significantly lower in 5 cm insoles than in 1 cm and 3 cm insoles. The mean plantar foot pressure followed the quality of the material of insoles were different significantly. In left, the mean plantar foot pressure of urethane poly-acetyl insole was lower significantly than urethane poly-acetyl inserted air insole, power-gel insole and jelly insole. And the mean plantar foot pressure of urethane poly-acetyl insole was lower significantly than power-gel insole and jelly insole in right. We showed that 3 cm and 5 cm insoles in the height of insoles and Urethane poly-acetyl insole in the quality of material were suitable to reduce a fatigue which is felt in plantar foot during the walking.
