Purpose: The purpose of the study is to provide the clinical results of arthroscopic posterior cruciate ligament(PCL) reconstruction with preservation of the original PCL using transtibial tunnel and posterior transseptal portal. Materials and Methods: 36 patients underwent PCL reconstruction with achilles tendon allografts. We tried to preserve of the original PCL.At the final follow-up, patients were evaluated retrospectively by four measurements: Lysholm knee scores, IKDC grades, Telos stress radiography, and second look arthroscopy.Follow-up periods were from 12 months to 30 months. Results: The average Lysholm knee score improved from $66.0{\pm}8.67$ to $87.9{\pm}5.04$. Preoperative IKDC grades were abnormal in 15(41.7%) and severely abnormal in 21(58.3%), postoperative IKDC grades were normal in 6(16%),nearly normal in 24(66%), abnormal in 5(16%) and severely abnormal in 1(2%).The average side to side difference in Telos stress test decreased from $12.5{\pm}2.61(7{\sim}20)$ mm to $3.9{\pm}1.34(7{\sim}1)$ mm (paired sample T test, p=0.001) Conclusion: Arthroscopic posterior cruciate ligament(PCL) reconstruction with preservation of the original PCL using transtibial tunnel and posterior transseptal portal is useful surgical method.

Purpose: The purpose of this study was to examine relationship of preschool child and mother interaction, child's health status, health-related quality of life and social development. Also, it was intended to provide a basis for development of mother-child interaction programs. Methods: The present study was a descriptive research. Participants in this study were a convenience sample of 230 preschool children and their mothers. For the final analysis 209 questionnaires were used after eliminating questionnaires with incomplete responses. Data were analyzed using the SPSS 18.0 program. Results: The mean score for interaction between preschool child and mother was $3.96{\pm}0.55$ out of 5 points, for child health status, $3.75{\pm}0.62$ out of 5 points, for child's health-related quality of life, $83.89{\pm}10.20$ out of 100 points and for child's social development, $19.66{\pm}3.57$ out of 24 points. Positive correlations were found between interaction of preschool child and mother, child's health status, health-related quality of life, and social development. Conclusion: The results demonstrate the importance of the quality of the relationship between mother, the child's primary caregiver, and her child for the healthy growth and development of preschool children. It is suggested that intervention programs for preschool child-mother interaction should be developed using evidence based data.

Background: We vigorously reviewed patients' operation record who had adhesion of the Denonvilliers' fascia and found out most of these patients had prostatic bleeding after prostatic gland biopsies. We examined the magnitude of prostatic bleeding and frequency after biopsies and the relationship with oncological outcomes. Materials and Methods: A total of 285 patients were selected for the final analyses. Inclusion criteria were as follows: receiving MRI three weeks after biopsiesand laparoscopic radical prostatectomy within 300 days after biopsy. We divided the patients into two groups with (group A) or without (group B) prostatic bleeding. We examined the magnitude of prostatic bleeding after biopsies and the relationship with operation time (OT), positive surgical margin (PSM), biochemical recurrence (BCR) and other factors. Furthermore, we created a logistic-regression model to derive a propensity score for prostatic bleeding after biopsies, which included all patient and hospital characteristics as well as selected interaction terms, and we examined the relationship with PSM and BCR. Results: In all patients, the OT in the group B was shorter than the group A (p < 0.001). Prostatic bleeding was associated with PSM (p=0.000) and BCR (p=0.036). In this propensity-matched cohort, 11 of 116 patients in the group B had PSM as compared with 36 of 116 patients from group A (match-adjusted odds ratio, 4.30; 95%CI confidence interval, 2.06 to 8.96; P=0.000). In addition, eight of 116 patients in group B encountered BCR, as compared with 18 of 116 patients in group A (match-adjusted odds ratio, 2.48; 95%CI, 1.03 to 5.96; P=0.042). Kaplan-Meier analysis in the propensity matching cohort showed a significant biochemical recurrence-free survival advantage for being free of prostate bleeding after biopsies. Conclusions: Our findings in the present cohort should help equip surgeons to pay attention to careful excision especially for those who experienced deferred prostatic bleeding.

Purpose: To analyze the clinical results and second look arthroscopic findings of anterior cruciate ligament(ACL) reconstruction with a tibialis anterior tendon allograft and a hamstring tendon autograft. Materials and Methods: We reviewed the cases of athroscopic ACL reconstructions using allogenous tibialis anterior(TA) tendon and autogenous hamstring tendon done from March, 2002 to August, 2005 and followed-up more than 1 year. The 250 cases were included in this study and allogenous TA tendon was used in 150 cases and autogenous hamstring tendon in 100 cases. The mean follow-up period was 15 months and 14 months, respectively. The clinical evaluation was done by Lachman test, Pivot shift test, KT-1000 arthrometer and International Knee Documentation Committee(IKDC) knee score. Graft tension, synovial coverage were observed in cases of second look arthroscopy. Results: At final follow-up, there was no significance between the two groups in clinical examination. On second look arthroscopy, synovial coverage was better in autogenous hamstring tendon group than allogenous TA tendon group(p=0.005). But no difference was found in graft tension(p>0.05). Conclusion: There were no significant differences between the two groups in the clinical results. But autogenous hamstring tendon group had better synovial coverage than allogenous TA tendon group in second look arthroscopy.

The purpose of this study was to improve work performance conducted at an actual clinical site by determining the relationship among critical thinking disposition, problem solving ability, and work performance. In this study, 335 dental hygienists completed self-administered survey. Final analysis was conducted with a total of 331 responses, excluding 4 questionnaire with unreliable responses and non-responses. The results indicated that as the age, educational background, and work experience of the subjects increased, their critical thinking disposition and problem solving ability scores increased and were statistically significant. For work performance, average total score was high for age, educational background and work experience, but only age and work experience were statistically significant. Critical thinking disposition, problem solving ability and work performance of the subject were relevant, and all of them were significant. Work performance was also influenced indirectly by mediating problem solving ability in critical thinking disposition. In other words, both direct and indirect effects were significant, and the existence of partial moderating effect was verified. Thus, in order to improve work performance of dental hygienists, a multilevel educational process that can simultaneously improve critical thinking disposition and problem solving ability of dental hygienists needs to be developed. Therefore, it is expected that the new dental hygiene company will be able to perform without any sense of disparity in the clinical field; this will solve the gap between dental hygiene education and practical skills.

Purpose: The purpose of this study was to evaluate the radiologic and clinical outcomes after intercalary tricortical iliac bone graft with plate fixation for the nonunion of midshaft clavicular fractures. Material and Methods: Between September 2007 and May 2011, 10 patients who were treated by the intercalary tricortical iliac bone graft, with plate fixation for clavicle nonunion, were studied. The mean follow-up period was 30.7 (12~57) months. After the sclerotic bone was excised to the bleeding cortical bone, we interposed the tricortical iliac bone to provide structural support and restore clavicle length, and then fixed the plate and screws. The radiologic outcomes on the serial plain radiographs and clinical outcomes, according to UCLA, ASES and Quick DASH scores, were analyzed. Results: Bony union was obtained in all cases (100%) and the average union time was 18.4 (14~24) weeks. The average respective UCLA and ASES scores improved from 16.7 and 52.1 preoperatively to 27.4 and 83.6 postoperatively (p<0.05). The average Quick DASH score was 40.5, at the final follow-up. Complications were 2 shoulder stiffness, and one case had removal of device and arthroscopic surgery at 11 months, postoperatively. There were no implant failure or infection. Conclusion: Intercalary tricortical iliac bone graft, with plate fixation for the nonunion of midshaft clavicular fractures, is a good option that can provide structural support and restore clavicle length, as well as high union rate.

PURPOSE : For the reconstruction of large bone defect after tumor resection, it is possible to reuse the bone involved by tumor with some treatment to it. Several bone-reusing methods have been reported such as autoclaving, low-heat treatment(pasteurization) and intraoperative radiotherapy. We have used extracorporeally radiated autogenous bone graft for reconstruction after tumor resection, and analyzed the periods for junctional union, functional results and complications to know the indications of this method. METHODS : From Dec. 1993 to Sept. 1995, nine patients had taken autogenous bone graft with extracorporeal irradiation. Eight cases were osteosarcoma and 1 giant cell tumor. The graft sites were 5 in femur, 3 proximal tibia and 1 femur and tibia. Stage 3 was 1 case(GCT), Stage IIB 3 and Stage IIIB 5. After wide resection, surrounding soft tissue and intramedullary and extramedullary portion of the tumor were removed. Radiation was done in 5000cGy to the resected bone. Ender nails and bone cement were inserted and filled into the medulla to prevent fracture. RESULTS : Average follow-up period was 12.3(4 to 21) months. Average junctional union period in simple X-ray was 6.5 months in 4 cases. Average functional score following Enneking's criteria was 19(12-27). Complications were as follows ; condylar fractures and femur neck fracture in 4 cases, subluxation of the knee joint 3 and infection 1. Although local recurrence was detected in 1 case, the site of recurrence was not in the radiated bone but surrounding soft tissue. At final follow-up, no recurrence was found in one case(GCT), CDF 2, AWD 2, DOD 3, and died of chemotherapy related sepsis 1. CONCLUSIONS : Extracorporeally radiated bone autograft is considered to be a method for reconstruction of the large bone defect made by tumor resection, especially in the reconstruction around the joint.

In this study, we evaluated the physicochemical, microbial, and sensory characteristics of Makgeolli made with loquat fruits during fermentation. The pH values of all samples decreased after 3 days of fermentation, with a final pH ranging from 3.91 to 4.05. Total acidity increased (from 0.71 to 0.76%) from the addition of loquat fruits after 15 days of fermentation. Amino acid content increased (from 0.13 to 0.22%) with fermentation time after 15 days of fermentation. Total sugar and reducing sugar content decreased with fermentation, but was significantly higher with the addition of loquat fruit. The alcohol content of the loquat-added groups was also higher compared to the control group after 15 days of fermentation. The microbial and yeast count of all samples increased to its maximum after 3 days and then decreased after 5 days of fermentation. The sensory score of Makgeolli made with 3% loquat fruit showed higher values than other samples. The results of this study suggest that loquat effectively serves as a natural additive for improving the sensory qualities of Makgeolli and potentially other foods.

Purpose : The purpose of this study is to evaluate the results of revision surgery for failed anterior cruciate ligament (ACL) reconstruction using quadruple hamstring tendon autograft. Materials and Methods : From May 2000 to July 2002, six patients received ACL revision surgery using quadruple hamstring autograft for failed ACL reconstruction. Femoral tunnels were made 40 mm in depth and fixed with a cross pin and a bioabsorbable interference screw to fill the bone defect. In tibial tunnels, the grafts were fixed with Intrafix(Mitek, Norwood, MA). In case of tibial tunnel widening, additional screw-washer fixation was done. Follow up was at least 12 months postoperatively. Clinical assessments consisted of Lysholm knee scores, International Knee Documentation Committee(IKDC) evaluation form and manual maximal side to side difference using KT-2000 arthrometer. Results : The average Lysholm knee score improved from 77.2 preoperatively to 87.7 postoperatively. At the final IKDC evaluation, 1 case was graded as normal, 4 nearly normal, 1 abnormal. Mean side to side difference of manual maximum anterior displacement using the KT-2000 arthrometer was 1.8mm. The success rate was $83\%$. Conclusion : ACL revision surgery using quadruple hamstring autograft with double fixation is considered good procedure with successful results.
