Purpose: The aim of this study was to establish a simple formula to predict renal length in children using a Technesium-99m dimercaptosuccinic acid (DMSA) scan data, and to compare it with the formula derived from ultrasonography, which is widely accepted. Methods: Children who underwent a DMSA scan and ultrasonography were reviewed retrospectively, and those who had anatomical urinary tract abnormalities or urinary tract infections were excluded. Results: A total of 230 children (84 males and 146 females; age, 1 month to 16 years; mean age, $16.8{\pm}27.4$ months). Mean renal length measured by DMSA scan was longer than that by ultrasonography ($6.38{\pm}1.16$ vs. $6.02{\pm}1.14cm$; P < 0.001). Renal length was correlated with age, weight, height, and body surface area on the DMSA scan and ultrasonography, and showed the strongest positive correlation with height. The following formulae were established to predict renal length: mean renal length (cm) = 5.433 ${\times}$ height (m) + 2.330 (R2, 0.833) using the DMSA scan data, and mean renal length (cm) = 5.367 ${\times}$ height (m) + 2.027 (R2, 0.853) using ultrasonography data. Conclusion: We propose a simple height-based formula to predict renal length in children using a DMSA scan data, and validate it by comparing with ultrasonography formula.

The purpose of this study is to identify the body images of patints with low back pain and their status on adjustment of daily living. The data were collected from 11 general hospitals during Feburary 2, 1987 through May 30,1987. One hundred and ninety five subjects having physical therapy treatment because of low back pain were analyzed. For measurement of body image, 11 pairs of adjectives were used on semantic differential scale, and for measurement of adjustment of daily living, 10 items were used on a likert type scale. Results of the study are summerised as follows. 1. The average patient age were 34yeats and 62% of the patients were men. High school grade completed were 43.1% and Cause of Low Back Pain were respctively;Unknown etiology 31.8%, lifting heavy objects 27.7%, Traffic accident and injury 17.9%. Types of treatment were;medication plus physical therapy 54.9%, physical therapy only 22.6%. Average treatment duration were 24.5 months. 2. There were significant difference in the body image between before low back pain and after low back pain. The body image before low back pain were 59.89(Mean) but after low back pain were 37,24(Mean) and two groups were statistically significant (t=21.3, p<0.00l). 3. there were no significant difference in the body image between the male and female.(t=1.49, p＞0.05) 4. The correlation between body image and adjustment of daily living. in both sexes showed positive correlation coefficient; male(r=0.4648, p<0.00l) female(r=0.4516, p<0.00l) respectively. It means that patients with positive body image can adjust well in daily living. 5. The relation between the body image and general variables revealed sigificant difference with occupation and age.(F=2.12 p<0.05, F=3.48 p<0.05). That is different occupation and different age groups can show different body image. In conculsion with the above results, It is my strong belief that multidisciplinary approach including the concept of body image and patient education about postural care, activities of daily living, lifting mechanics should be applied in treating and dealing with those patients.

Objective: The aim of the present study was to examine the relationship among male age, strict morphology, and sperm chromatin structure and condensation. Methods: Sperm samples from a total of 100 men underwent semen analysis, and sperm chromatin structure and condensation were assessed with toluidine blue (TB) and aniline blue (AB) tests. Results: Prevalence of strict morphology of less than 4%, and abnormal sperm chromatin structure and condensation did not show any statistically significant differences according to male age (p=0.605, p=0.235, and p=0.080). No significant correlation was demonstrated among age of male partners, strict morphology, and abnormal sperm chromatin structure using TB and AB tests. However, abnormal sperm chromatin condensation was positively associated with sperm chromatin structure (r=0.594, p=0.000) and showed negative correlation with strict morphology (r=-0.219, p=0.029). Conclusion: The tests for sperm chromatin condensation showed a significant association with strict morphology. Further study is needed to elucidate the relationship between clinical outcome and sperm chromatin tests.

The objective of the present study was to investigate the effects on growth performance, meat quality parameters and fatty acids of meat by restricted diet amount on finishing Berkshires. A total of 180 pigs (Berkshire, initially 52 kg BW) at 100 days of age were allotted in arrangement in a completely randomized design (10 pigs per pen), blocked arrangement of treatments with 3 replications. The variables were market ages (180, 200 and 220 days) and in which was also included sex (gilts and barrow). All the pigs were restrictively fed so that day could be marked at 103 kg. Pork quality was evaluated from 4 pigs of each treatment. Average daily gain (ADG) and average daily feed intake (ADFI) were decreased (p<0.05) with age increase. The ratio of feed to gain was increased (p<0.05) at 200 and 220 days compared to that of 180 days. Moisture and crude protein of longissimus dorsi muscle (LM) at 180 days were increased (p<0.05) compared to 200 and 220 days. Crude fat was increased (p<0.05) by age and crude ash was lower (p<0.05) at 180 days than at 220 days. Red to green meat color scale (CIE a$^{*}$) increased (p<0.05) at 200 and 220 days more than at 180 days. Regarding fatty acid composition in meat, saturated fatty acids (SFA) was increased more (p<0.05) at 220 days than at 180 and 200 days. The results indicate that even with a restricted diet of low nutrient supplement, there was an improvement in Berkshire meat quality parameters.

Age and growth of Hemibarbus labeo caught from Goe-san Lake in South Korea from March to November, 2011, were studied. A total of 201 specimens was collected, ranging from 110 to 580 mm in total length (TL). Males and females made up 47.9% and 52.1% of the sample, respectively. Marginal increment analyses showed that vertebral increments, each composed of one opaque and one hyaline zone, were deposited annually. Opaque edges were prevalent from June to July. The relationship between TL and vertebral radius was linear, with equations of R = 0.008TL - 0.208 (male) and R = 0.009TL - 0.272 (female). Regression equations between TL and total weight (TW) were $TW=9{\times}10^{-6}TL^{2.987}$ (male), $TW=8{\times}10^{-6}TL^{3.014}$ (female), and $TW=9{\times}10^{-6}TL^{2.988}$ (combined sexes), according to the von Bertalanffy growth equation. Back-calculated TL was expressed using the von Bertalanffy equation as follows: $L_t=438.25(1-e^{-0.175(t+0.164)})$ for males, $L_t=483.36(1-e^{-0.147(t+0.115)})$ for females, and $L_t=464.86(1-e^{-0.162(t+0.176)})$ for the sexes combined. The growth performances were 4.526, 4.536, and 4.544, respectively.

Purpose: The purpose of this study was to investigate the degree of suicidal risk, meaning in life, and life respect in various ages of patients and identify factors influencing their life respect. Method: The participants were 229 patients in a public hospital who completed questionnaires. Data were analyzed using descriptive statistics, t-test, Fisher's exact test, ANOVA with Duncan post hoc test, and multiple regression. Results: There was a negative correlation between the meaning of life and life respect in the old age group (r=-.23, p=.02) and all subjects (r=-.14, p=.01) after controlling for age. Factors significantly influencing life respect were gender (${\beta}$=0.11, p=.050) and educational status (${\beta}$=-0.17, p=.022), and the multiple regression model explained 16.7% of the variance in all subjects (p<.001). In the early adulthood group, factors significantly influencing the life respect were gender (${\beta}$=0.18, p<.001) and suicidal thoughts (${\beta}$=0.21, p=.028), and the multiple regression model explained 6.8% of variance in all subjects (p=.001). Conclusion: The results of this study suggest that suicidal prevention and educational programs for increasing an appreciation of life should consider subject's characteristics, such as gender and educational status.

Purpose: We measured the Oswestry Low Back Pain Disability Index (OLBPDI) and related factors in patients with low back pain. Methods: The sample consisted of 50 patients who received physical therapy at the physical therapy units of the Andong Seoul Sintong Clinic, St. Luke Clinic, and Yeongju Seoul Sintong Clinic in Andong and Yeongju city from October, 2007, to February, 2008. The OLBPDI questionnaire was administered by 5 physical therapists as a cross-sectional study. Student's t-test and analysis of variance (ANOVA/Tukey and Scheffe) were used to analyze OLBPDI score differences. We also used nonparametric statistic analysis (Wilcoxon rank sum test, Median test). Pearson correlation analysis (Spearman correlation analysis) was used to analyze the relationship between OLBPDI and the visual analogue scale (VAS). Multiple regression analysis was performed to determine the effects of independent variables on pain scores as defined by the OLBPDI. Results: The average patient age was 37.1 years (range: 18$\sim$78 years old), and time from onset was 21.7 months (1$\sim$180). OLBPD and VAS scores were 12.70 (3.0$\sim$28.0) and 5.14 (1$\sim$8), respectively. OLBPDI scores were 14.4 in patients taking medicine and 11.57 in those who did not. There was a statistically significant relationship between OLBPDI and VAS (r=0.54, p=0.0001; r=0.55, p=0.0001 by Spearman coefficient). Gender ($\beta$=6.14, p=0.0124), age ($\beta$=-2.01, p=0.0324), weight ($\beta$=0.31, p=0.0222), time from onset ($\beta$=1.54, p=0.0044), and VAS score ($\beta$=1.59, p=0.0004) were significantly associated with OLBPD by multiple regression analysis. Conclusion: Variables associated with OLBPD were gender, age, weight, time from onset, and VAS score. Collecting information on the pain index using OLBPDI was acceptable to patients with low back pain. Further research should explore the pain index by using larger sample sizes and longer follow-up periods.

Purpose: A eutectic mixture of local anesthetics (EMLA$^{(R)}$) cream has been used as a topical anesthetic to reduce the pain of procedures penetrating the skin. It is generally applied for 40 to 60 minutes before the painful procedure. Because of the long application period, EMLA$^{(R)}$ is not useful in the emergency department (ED). The purpose of this study was to determine whether a 20-minute application of 9.6% lidocaine would be useful in reducing the pain of routine peripheral intravenous cannulation in the ED. Methods: We examined 27 male and 19 female patients ages over 18 years of age who required intravenous cannula insertion. Intravenous insertion was performed on 46 patients: 24 patients in the placebo group (mean age: 40.0 years) and 22 in the 9.6% lidocaine group (mean age: 37.6 years). The 9.6% lidocaine or placebo gel was applied and covered with an occlusive dressing for 20 minutes. Pain was scored by the patients using a 0- to 10-cm visual analogue scale. Results: The patients in the 9.6% lidocaine group (mean pain score: 3.4) experienced less pain than those in the placebo group (mean: 5.3), and the difference was statistically significant (p=0.029). Conclusion: We concluded that a 20-minute application of 9.6% lidocaine is safe and effective for reducing pain associated with venipuncture.

Using the hematofluiorometer normal values of the erythrocyte zinc protoporphyrin(ZPP) and ZPP/Heme ratio were measured in 312 males and 163 females aged from 6 month to 73 years old and compared with those of anemic persons. The mean$\pm$SD values of ZPP of normal Koreans were 28.5$\pm$6.4($\mu\textrm{g}$/dl) in males and 3.18$\pm$7.7 in females. the mean$\pm$SD of ZPP/Heme ratio were 49.5$\pm$12.3($\mu$mol/mol heme) in males and 62.0$\pm$15.8 in females. The difference in the mean ZPP and ZPP/Heme ratio values between male and female subjects were statistically signficant(p<0.0001) In male subjects the mean ZPP and ZPP/Heme ratio of the age groups less than 15 years old were higher than adult groups and the difference between age groups was significant(p<0.005 and p<0.0001 respecti-vely) The normal upper limit of the mean$\pm$2SD in normal male and female subjects were 41.3 and 47.2 for ZPP and 74.1 and 93.6 for ZPP/Heme ratio respectively. The mean values of ZPP and ZPP/Heme ratio measured in the anemic persons were higher than those of normal subjects and did not show any significant difference by the sex and age groups except in 6-14 years male groups. The test specificity(positivity) analyzed in the anemic persons by the cut-off values calculated from the normal data were 50.6% for ZPP and 73.0% for ZPP/Heme ratio. The correlation analysis between blood hemoglobin and erythrocyte ZPP or ZPP/Heme ratio in the total 801 normal and anemic subjects showed that there are very high logarithmic correlation between the hemoglobin levels and ZPP/Heme ratio (r=-0.8339) and high correla-tion between the hemoglobin levels and ZPP concentrations(r=-0.6372) These results suggested that the measurement of the erythrocyte ZPP and ZPP/Heme ratio with the hematofluorometer can be a usuful screening method for iron deficiency anermin because they provide a reliable immediate results with a small amount of sample and are relatively simple and inexpensive.
