Red ginseng marc is a by-product of Korean red ginseng (panax ginseng CA Meyer) and contains ginsenoside which has pharmacological effects. The Korean red ginseng marc was fermented with Bacillus subtilis (RGMB). This study was carried out to investigate the RGMB effect on swine immunity. The variation of ginsenoside depending on the RGMB fermentation time was analyzed. Swine (Landrace${\times}$Yorkshire) were divided into control group (basic diet) and RGMB group (RGMB 1% diet). One percent RGMB was fed to the RGMB group for 28 days. The biochemical parameters, cytokine and immunoglobulin were analyzed. For 48 hours of fermentation on RGMB, ginsenoside Rb1 had increased 180.94%, Rg3 235.85%. Rg1 wasn't detected before fermentation, but was detected after 48 hours of fermentation. The RGMB had effect of deceasing initial AST concentration $79.33{\pm}12.85U/L$ to $54.00{\pm}14.46U/L$ in final and was significantly lower (P<0.05) than control in final. In final RGMB had significantly lower (P<0.05) ALT concentration of $48.57{\pm}8.26U/L$ comparing with control group of $65.43{\pm}10.31U/L$. RGMB had the effect of significantly decreasing (P<0.05) $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration of $2.44{\pm}1.31ng/mL$, $0.71{\pm}0.36ng/mL$ and $0.51{\pm}0.21ng/mL$. The IgA concentration had significantly increased (P<0.05) in RGMB group of $0.56{\pm}0.06mg/mL$ in final. These results demonstrate that RGMB has effect of increasing immunity and practicable to use as feed additives on swine.

Background: Tuberculous pleurisy is the leading cause of pleural effusion in Korea. And differential diagnosis of tuberculous pleurisy with other cause is clinically very important. Traditional diagnostic methods such as routine analysis of pleural fluid, staining for acid-fast bacilli or pleural biopsy have major inherent limitaion. This study was designed to evaluate the significance of pleural fluid polymerase chain reaction(PCR) and adenosine deaminase (ADA) activity in early diagnosis of tuberculous pleurisy. Material and Method: Between March 1996 and July 1997, 198 patients with pleural effusion reviewed retrospectively. The study group included 112 cases with tuberculous effusion and 86 cases with non-tuberculous effusions, whose diagnoses were confirmed by pleural biopsy, microbiological methods, or cytology. We compared the results of PCR and pleural fluid levels of ADA between tuberculous and non-tuberculous effusions. Result: Mean age was 47.54$\pm$19.52 years(range 2 to 85 years). The positive rate of PCR was significantly higher in tuberculous group than non-tuberculous group(p<0.05). The sensitivty, specificity, positive predictive value(PPV), and negative predictive value(NPV) for PCR were 31.7, 90.9, 83.0, and 48.8%, respectively. Mean ADA activity was significantly higher in tuberculous group than non-tuberculous group(83.2 U/L vs 49.8 U/L)(p<0.05). With diagnostic thresholds of 40 U/L, the sensitivity, specificity, PPV, and NPV of ADA for tuberculosis were 75.9, 70.9, 77.3, and 69.3% respectively. At a level of 70 U/L, the sensitivity, specificity, PPV, and NPV of ADA for tuberculosis were 70.1, 75.9, 82.9, and 60.3% respectively. Conclusion: PCR is very highly specific, but less sensitive methods in diagnosis of tuberculous pleurisy. But ADA level of pleural fluid has acceptable sensitivity and specificity in diagnosis of tuberculous pleurisy. ADA activity is more useful test in the evaluation of pleural effusions.

Purpose: The purpose of the study was to investigate the effects of an integrated self-management program on self-management, glycemic control, and maternal identity in women with gestational diabetes mellitus (GDM). Methods: A non-equivalent control group non-synchronized quasi-experimental design was used. A total of 55 women with GDM were recruited from Cheil General Hospital, Seoul, Korea and were assigned to an experimental (n=28) or control group (n=27). The participants were 24-30 weeks pregnant women who had been diagnosed with GDM as of July 30, 2010. The program was conducted as a 1 hour small group meeting 3 out of 5 times and by telephone-counseling 2 out of 5 times. The integrated self-management program was verified by an expert panel. Results: Although there was no significant reduction in HbA1c (U= -1.17, p=.238), there were statistically significant increases in self-management (U= -3.80, p<.001) and maternal identity (U= -4.48, p<.001), and decreased 2-h postprandial glucose levels (U= -2.43, p<.015) in the experimental group compared to the control group. Conclusion: These findings suggest that an integrated self-management program for women with GDM improves self-management, maternal identity, and glycemic control. Further studies are needed to identify the effects of an integrated self-management program on pregnancy and neonatal outcomes.

Objectives : The objectives of this study is to develop a mouse model similar to Taeeum-type by inducing Lung fibrosis with bleomycin, and to determine adequate concentration of bleomycin. Methods : The subjects were divided into six groups: normal, obesity induced group, and bleomycin administered 0.015U, 0.03U, 0.06U, and 0.09U(U/100g bw) concentrations respectively. Each concentration of bleomycin was dissolved in distilled water, and administered through Intra-Nazal-Trachea injection method. Food intake and body weight were measured at regular time weekly. At the end of the experiment, blood was gathered by cardiac puncture for biochemical examinations, organs were removed for histological examinations, and weigh and mRNA genes was analyzed. Result : Mice administered with bleomycin at 0.015U and 0.03U showed body and fat weight gain, and increased blood total cholesterol, LDL-cholesterol, glucose, and free fatty acid level. Fat related genes also showed higher level than the control group. Obesity was most strongly induced in the mice administered with 0.03U of bleomycin. On the other hand, when bleomycin was administered at concentrations above 0.06U, a model of obesity mouse was not created due to rapid emphysema inflammation and weakness. Conclusions : Mice were most vulnerable to obesity when bleomycin was administered at a concentration of 0.3 to cause liver damage. Bleomycin concentration over 0.06U did not cause obesity-induced mice, due to severe damage in liver.

Purpose: This study aimed to evaluate the effectiveness of a customized health promotion program (CHPP) on depression, cognitive functioning, and physical health of elderly women living alone in the community. Methods: A randomized comparison of pre-and post-test design was used with 62 participants assigned to either an intervention (n=32 in seven clusters) or a control group (n=30 in seven clusters) in 14 areas of a town. The final sample included 30 intervention participants who completed the CHPP for 10 weeks, and 26 control participants. The intervention group participated in the CHPP weekly; they were provided with instructions about coping with their chronic illnesses, lifestyle modification, risk management, providing emotional support to each other, and floor-seated exercise, which they were encouraged to do three times a week in their homes. Results: Significant group differences were found in depression (U=48.50, p<.001), cognitive functioning (U=2.50, p<.001), left arm flexibility (U=251.50, p=.023), right arm flexibility (U=225.00, p=.007), static balance (U=237.00, p=.012), and gait ability (U=190.50, p=.004). However, there were no significant differences in bothgrip strength and muscle mass between the two groups. Conclusion: The findings indicate that CHPP was overall effective at improving depression, cognitive functioning, and physical functioning of elderly women living alone, and could therefore be considered a positive program for community-dwelling elderly women living alone.

Octacosanol is known to enhance endurance activities, control cholesterol in body and improve the function of cardiopulmonary. Citrulline, which is main compound of watermelon, is known to improve angiectasia through stimulating production of nitric oxide. To improve endurance activity swimming test on rats was carried out using four samples such as 1$\%$ octacosanol, citrulline, the extracts of barks of watermelon and products, mixture of 1$\%$ octacosanol and the extracts of barks of watermelon (6 : 4). Biochemical assays on the liver and serum of tested rats were also performed using commercial analysis kits. In result, it was shown that swimming time of III group increased by 26$\%$ and that of V group was increased by 22$\%$ at the swimming test. As a result of biological assays on the liver and serum of tested rats it was possible to confirm stability of toxicity When compared with creatine kinase of control group (549.11$\pm$39.15 U/l) citrulline (644.11 $\pm$50.67 U/l) and products group (646.00$\pm$46.99 U/l) were largely increased. When compared with inorganic phosphate of control group (12.01$\pm$0.75 mg/이), citrulline (13.03$\pm$0.94 mg/dl) and products group (12.90$\pm$0.55 mg/dl) showed similar results. Also, when compared with lactic acid and glucose of control group (152.91 $\pm$ 13.45, 103.00$\pm$ 8.69 mg/dl), citrulline (125.53$\pm$15.54, 83.75$\pm$7.29 mg/dl) and products group (135.26$\pm$11.50, 78.57$\pm$9.79 mg/dl) were largely decreased. As these test results, it was determined that 1$\%$ octacosanol and extracts of barks of watermelon had some effect of improving endurance activity. Futhermore, it was thought that it could be used as source of functional food.

Purpose: To determine predictive factors for detecting renal parenchymal damages (RPDs) in infants with recurrent febrile urinary tract infection (fUTI). Methods: From January 2015 to December 2021, 102 infants with recurrent fUTI and who underwent ^99mTc-dimercaptosuccinic acid (DMSA) renal scan in our hospital were included in this study. Controls included infants with normal DMSA results performed 3 months apart from the 2nd episode of fUTI. DMSA-positive group included infants with positive DMSA results performed 3 months apart from the 2nd episode of fUTI or at the 3rd episode of fUTI. The recurrence rate, causative bacteria, renal size discrepancy of both kidneys, and laboratory findings including C-reactive protein (CRP) and spot urine sodium-to-potassium ratio (uNa/K) were compared between both groups. Results: Only 3.8% of 79 infants with a 2nd episode of fUTI showed positive DMSA results. fUTI recurred more frequently within 12 months of follow-up in the DMSA-positive group than in the control group (69% vs. 13%, P<0.001). CRP values were significantly higher in the DMSA-positive group than in the control group (7.3 mg/dL vs. 3.7 mg/dL, P<0.001). Spot uNa/K were significantly lower in the DMSA-positive group than in the control group (0.6 vs. 1.1, P<0.001). Conclusions: Congenital renal scar and RPDs on the DMSA scan were more frequently found in infants with recurrent fUTI than those in the control group. High CRP values and low spot uNa/K in acute infections were helpful in predicting the presence of RPD in infants with recurrent fUTI.

The purpose of this work is to examine the viability of employing the prosody cloning technique in teaching English prosody. Ten native speakers of Korean high school students with similar level of English proficiency participated in the poem self-study experiment. Five of them were grouped into the experimental group and the remaining five into the control group. One popular English poem from a high school textbook was selected and its recording by a professional native speaker of English was used in the experiment. The members of the two groups made a recording of the poem both before and after the experiment. For the study material, the experimental group used their own recorded utterances with their prosody cloned from the professional English speaker, while the control group used the utterances of the professional speaker alone. The acoustic analysis of the recordings by the prosodic foot both before and after the experiment showed that the experimental group performed slightly better than the control group in the realization of the intensity contour of the poem. There were no significant differences in the realization of the intonation contour and segmental durations between the two groups. The recording after the experiment was also subjectively evaluated by a native speaker of English and the scores for the experimental group were slightly higher than the control group. These findings suggest that the use of English poems with the help of the prosody cloning technique is a potentially viable approach to teaching English intonation to high school students. A long-term study with more students is necessary.

Purpose: Gastric cancer is one of the most common cancers in Korea, and the proportion of upper-third gastric cancers has been steadily increasing over the last two decades. This study aimed to evaluate the effect of tumor location on gastric cancer prognosis. Materials and Methods: We retrospectively reviewed 2,466 patients who underwent gastrectomy for pathologically proven gastric cancer between January 2011 and December 2016. The patients were divided into an upper-third group (U group; n=419, 17.0%) and a middle- and lower-third group (ML group; n=2,047, 83.0%). Clinicopathological characteristics, overall survival (OS), and recurrence-free survival (RFS) after surgery were compared. Results: The U group had more advanced disease than the ML group and a higher incidence of N3b disease for T3 (12.0% vs. 4.9%, p=0.023) and T4 tumors (33.3% vs. 17.5%, p=0.001). The 5-year RFS rate for stage III disease was marginally lower in the U group than that in the ML group (47.1% vs. 56.7%, p=0.082). The upper third location was an independent prognostic factor for both OS (hazard ratio [HR], 1.350; 95% confidence interval [CI], 1.065-1.711) and RFS (HR, 1.430; 95% CI, 1.080-1.823). Conclusions: Upper-third gastric cancer shows extensive node metastasis compared to those located more distally in ≥T3 tumors. The upper third location is an independent prognostic factor for both OS and RFS and may have an adverse impact on RFS, particularly in patients with stage III gastric cancer.

Purpose: Designed to examine the effects of aerobic exercise therapy on elders' physical functions. Methods: Selected from an elderly welfare center in an agricultural district located in N City. Thirty seven elders were selected in the experimental group and 38 in the control group, and all the subjects aged over 65. Collected data were statistically analyzed by SPSS/PC 12.0 Win. Detailed data analysis methods were Chi-square, Fisher's exact test, Kolmogorov-Smirnov test, t-test, Mann-Whitney u-test, paired t-test, and Wilcoxon's rank sum test. Results: The first hypothesis "The experimental group who had the aerobic exercise therapy will have greater development in lower leg muscular strength compared to the control group" was supported (t=8.95, p<.001). The second hypothesis "Aerobic exercise therapy participants will show greater development in lower leg endurance" was supported (t=6.12, p<.001). The third hypothesis "Aerobic exercise therapy participants will show greater development in flexibility" was supported (U=49.00, p<.001). The forth hypothesis "Aerobic exercise therapy participants will show greater development in balance" was supported (U=322.00, p<.001). Conclusion: The aerobic exercise therapy showed positive effects on physical functions of the elderly in a rural area.
