Objective: The aim of this study was to investigate enuretic children attending oriental hospital and classify subtypes and evaluate possible factors that enhance or hamper of continence. Methods: Children attending kyeongju dongguk oriental hospital pediatrics between January 2000 and December 2003 with chief complaint of nocturnal enuresis were enrolled. The data of present symptoms and improvement progress was collected via telephone interviews with their parents. Results: The total number of children was 61. 32 of them were male and 29 female. Sex ratio was 1.1:1. Patient under 6 years of age was 68.8%. Using acupuncture, acupressure or chimsband with herb medicine, treatment frequency was increased. Patients with nocturnal enuresis(NE) was 48, and primary nocturnal enuresis(PNE) 39, secondary (SNE) 9. 13 was impossible to diagnose. The ratio of male to female was 1:1.09. PNE was 4 times as many as SNE. Male was predominent in PNE, and female in SNE. In the progress of PNE, male and female were similiar. but SNE, male was all cured, female remained 50%. And elapsed time of male to improve was longer than that of female. In the progress of improvement, many parents mentioned that their child was improved spontaneously regardless of subtype. Conclusion: We consider age, sex distinction, subtype, bladder symptoms, frequency, time of progress as influencing factor of prognosis, but failed to verify significance. To develop guideline of NE and find influencing factor of prognosis, more prospective study through taking history carefully and using questionnaire is needed.

A parallelization of the bi-conjugate gradient solver for the pressure equation of the CUPID (component unstructured program for interfacial dynamics) code, which was developed for analyzing the components of a pressurized water-cooled reactor, was studied in a symmetric multi-processing system. The parallel performance was investigated for three typical parallel programming models (MPI, OpenMP, Hybrid) by solving incompressible backward-facing step flow at various grid resolutions. It was confirmed that parallel performance was low when problem size was small or the memory requirement for each thread was considerably higher than the cache memory. Furthermore, it was shown that MPI was better than OpenMP regardless of the problem size, and Hybrid was the best when the number of threads was relatively small.

Obejectives : To investigate the clinical effect of electroacupuncture and bee venom acupuncture for benign prostatic hyperplasia(BPH) symptoms. Methods : Among 39 outpatients who were treated at a BPH clinic, 8 were finally selected for analysis by charts-review, retrospectively. They were treated by electroacupuncture and bee venom acupuncture more than 3 times. We estimated the effectiveness of the treatments by using the International Prostate Symptom Score (IPSS) questionnaire and checking their nocturia frequency. On the basis of these variables, we analyzed the statistical significations of symptom improvements. Results : Among 8 patients, the IPSS and nocturia frequency showed significant improvement after the final treatment compared with baseline (P = .0078, P = .0078). The IPSS significantly decreased even after the 1st treatment and also after the 2nd treatment compared with the baseline (P = .0078, P = .0078). The IPSS at post final-treatment, post 1st- and post 2nd treatment also showed significant improvement compared with IPSS at baseline in 6 severe symptomatic patients(P = .031, P = .031, P = .031). Nocturia frequency decreased after the 1st treatment compared with baseline and showed significant improvement between baseline and post 2nd treatment (P = .0078). Conclusions : In a retrospective and cross-sectional study investigating the clinical effects of electroacupuncture and bee venom acupuncture on BPH, these treatments proved to have significant therapeutic effects, particularly for various symptoms involving frequent nocturia.

Objectives: The purpose of this study was to investigate the clinical effects of HongYi pharmacopuncture monotherapy on female voiding dysfunction. Methods: Korean medical practitioners who used HongYi pharmacopuncture to treat female patients complaining of dysuria were surveyed. They performed a retrospective chart review of 31 female patients who visited their Korean medical clinic for dysuria. General characteristics, marital status, urologic medical history, International Prostate Symptom Score (IPSS), International Consultation on Incontinence Modular Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), and related adverse events were examined. Results: Of 31 cases received, 29 were selected for analysis. Two cases were excluded because treatment was not continued through four weeks. In all cases, IPSS and ICIQ-FLUTS scores were significantly decreased after treatment. Adverse reactions occurred during treatment in four cases. Conclusions: These results suggest that treatment by HongYi pharmacopuncture is effective in improving lower urinary tract symptoms in women. Further studies will be needed for evaluation of clinical responses, to evaluate the safety and efficacy of HongYi pharmacopuncture treatment for female patients complaining of dysuria.

Purpose: Keloid is a clinical term characterized by elevation and extension of scar tissue beyond wound margin. Currently, there is no known treatment that shows consistent effect in all patients. Postoperative radiation therapy is known to prevent recurrence of keloid. Methods: We reviewed data of patients who had undergone operation or operation followed by radiation therapy at our institute for the last 12 years. Follow up was possible in 39 patients(21 patients treated only by operation and 18 treated by operation and radiation therapy) We then investigated recurrence in both groups by VAS score. By mail, patients were asked to score their current condition on the bar in 4 aspects(itching, pain, mass lesion(by patients and other persons)). Two criteria were used for defining successful treatment. One is the case which total VAS score was 0, and the other is sum of VAS score of mass lesion was 0 to 5. Results: In the former, recurrence rate is 90.5% in operations-only group but 66.7% in operations plus radiation therapy group(p < 0.05). In the latter, recurrence rate is 66.7% in operation-only group but 22.2% in operations plus radiation therapy group(p < 0.05). Conclusion: These results shows postoperative radiation therapy is effective method in keloid treatment.

Purpose: To estimate the prevalence and incidence of patellar tendinitis, to discover the patellar tendinitis in top level male volley ball players. Materials and Methods: Thirteen members of the male adult volleyball players were included in this study. From history and physical examination, 3 of the 13 players had patellar tendon pain associated with activity and were diagnosed as patellar tendinitis at the time of the study. Investigators were blinded about the injury status of the players. For all players, data such as age, volleyball experience, amount of training and competition hours were recorded. Results: Of the thirteen cases, two spikers complained pain on the lower pole of the patella, one setter on the upper pole. Conclusion: This findings suggest that patellar tendinitis in the volleyball players are influenced by the amount of the practice and their position. In most cases, the supervised control of the practice will reduce the overuse injuries in the volleyball players.

Acute flank pain from urolithiasis is the most common condition in people visiting emergency rooms. This study is to evaluate the usefulness of color Doppler in detecting ureteral stones in patients without hydronephrosis. We performed ultrasonography and retrospective analysis on 161 patients who were suspected of urinary stones through plain radiography of the kidney, ureter, and bladder examination or urine tests that showed positive signs of hematuria. In ultrasonography, a total of 154 (95.6%) cases from the 161 patients were diagnosed with ureteral stones. In color Doppler, ureteral stones with twinkling artifact (TA) in the absence of hydronephrosis was shown in 18 (85.7%) cases of the 21 patients(p<0.001). The use of color Doppler has a high diagnostic efficacy for the detection of indistinguishable stones, non-dilatational ureteral stones, and middle ureter stones.

The purpose of this study was to evaluate the cause of lens luxation and to determine the frequency of vision loss, glaucoma, cataract, and corneal edema before and after intracapsular lens extraction (ICLE). The medical records of 8 dogs underwent ICLE for the correction of anterior lens luxation at the Veterinary Medical Teaching Hospital of Seoul National University from August 2005 to September 2007 were reviewed. The most frequently affected breed was Miniature Poodle (n = 3). The mean age was $10.8{\pm}2.1$ years. Preoperatively, 5 eyes (67.5%) with anterior luxation had secondary glaucoma, 7 eyes (87.5%) had vision loss, and all eyes (100.0%) had corneal edema. Four weeks after ICLE, 6 eyes (75.0%) had normal intraocular pressure (IOP), and 4 eyes (50.0%) regained vision. Corneal edema was reduced after ICLE in all eyes, but still remained in 4 eyes. It was considered that ICLE was beneficial in the management of anterior lens luxation, but the eyes without glaucoma before ICLE had more favorable prognosis than eyes with.

Purpose: The purpose of this study was to evaluate the surgical success of bone reconstruction of the severely atrophic maxilla using autogenous block bone onlay graft from the ramus and ilium prior to dental implantation. And we measured the amount of vertical height change Material and Methods: 26 partially edentulous patients(32 case) who needed block onlay bone graft before implant placement in posterior maxillary area from 2002 to 2009 were selected for this study. Patients consisted of 20 males & 6 females and the average of their age was 54.2. Patients who were treated with ramal bone were 19 case and patients who were treated with iliac bone were 11 case. Digital panoramic X-ray was taken at the day of surgery, 3 months and 6 months later after the surgery. Vertical height change & resorption rate of grafted bone were measured with the same X-rays and compared Results: Two out of 32 bone grafts had to be removed because of inflamation at the grafts area(97.3%). The mean of radiographic vertical height change(change rate) of post-op. 3 month was 0.54mm(8.5%)and 6 month was 0.99mm(15.9%). Compairing to intraoral donor site(ramus), iliac bone had more vertical height change(1.18mm) at 6 month after surgery. Conclusions: Within the limit of this study, autogenous block onlay grafts can be considered a promising treatment for severely atrophic maxilla.

Introduction: Maxillary malignant tumors are primary tumors of the maxillary gingiva, sinus, and palate. The purpose of this study was to research the prognosis and treatment modalities of maxillary malignant tumors. Materials & Methods: For this study, 52 patients, who were treated after being diagnosed for maxillary malignant tumors at the department of OMFS at Yonsei University college of Dentistry from January 1997 till April 2008, were classified, then the prognoses of these patients were evaluated depending on their primary site, histopathology and treatment modalities. The results of this study showed that the most common primary site for maxillary malignant tumors was the gingiva and for histopathology, squamous cell carcinoma. Result & Conclusion: The average follow up period was 32.7 months. In determining prognosis, the most important factors were the control of local site and metastasis of cervical lymph nodes. Therefore, for a better prognosis, a tumor free margin during surgery and a periodic follow up to examine for metastasis to cervical lymph nodes and other organs are necessary.
