In this paper, we made sausages which included 1% black garlic extracts at $15^{\circ}Bx$ mixed with 0.3% dried powders of Curcuma longa L. (ST1), Opuntia ficus-indica var. saboten (ST2), Asparagus ocinals L. (ST3) and Aloe vera (ST4), respectively, and evaluated the quality of the sausage by instrumental analysis and sensory evaluation. The sausages were stored at $8^{\circ}C$ for 4 weeks. In terms of color intensity, ST2 provided the highest lightness (L) and redness (a), while the yellowness (b) was the highest in ST3. In the initial duration, the control group of sausage showed the highest texture measurement. ST4 had the lowest pH level (highest acidity). These outcomes decreased as the storage time became longer. In the initial storage duration, the ST4 had the highest total sugar content ($17.64{\pm}0.92mg/100g$), and this increased with longer storage duration. Since the contents of TBARS for the proposed sausages had been incremented, the initial contents were generally lower than those of the control sausages. The ABTS radical scavenging activity was performed as $89.11{\pm}0.66{\sim}99.22{\pm}0.09%$ at the $1000{\mu}g/mL$ level during the initial day of storage. To conclude, the sausages supplemented the black garlic with the proposed dried powders have a high chance of being a suitable commercial product for both customs and marketing eld.

Purpose: Long-term survivors of childhood cancer appear to have an increased risk for the metabolic syndrome, subsequent type 2 diabetes and cardiovascular disease in adulthood compared to healthy children. The purpose of this study was to investigate the frequency of the metabolic syndrome and associated factors in childhood cancer survivors at a single center in Korea. Methods: We performed a retrospective review of medical records of 98 childhood cancer survivors who were diagnosed and completed anticancer treatment at Samsung Medical Center, Seoul, Korea between Jan. 1996 and Dec. 2007. Parameters of metabolic syndrome were evaluated between Jan. 2008 and Dec. 2009. Clinical and biochemical findings including body fat percentage were analyzed. Results: A total of 19 (19.4%) patients had the metabolic syndrome. The median body fat percentage was 31.5%. The body mass index and waist circumference were positively correlated with the cranial irradiation dose (r=0.38, P<0.001 and r=0.44, P<0.00, respectively). Sixty-one (62.2%) patients had at least one abnormal lipid value. The triglyceride showed significant positive correlation with the body fat percentage (r=0.26, P=0.03). The high density lipoprotein cholesterol showed significant negative correlation with the percent body fat (r=- 0.26, P=0.03). Conclusion: Childhood cancer survivors should have thorough metabolic evaluation including measurement of body fat percentage even if they are not obese. A better understanding of the determinants of the metabolic syndrome during adolescence might provide preventive interventions for improving health outcomes in adulthood.

Purpose: This study was performed to evaluate the clinical outcomes of operative treatment using porous hydroxyapatite for intraarticular calcaneal fracture of joint depression type. Materials and Methods: Twenty patients with intraarticular calcaneal fracture were followed up for more than 1 year. The period to union was calculated to evaluate the osteoconductivity of porous hydroxyapatite used as bone graft substitute. The measurement of Bohler angle, Gissane angle and the degree of articular surface depression was performed through preoperative and postoperative radiographs. The clinical evaluation was performed according to hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) and scale of the Creighton-Nebraska health foundation (CNHF). Results: Bohler angle and Gissane angle had improved significantly from preoperative average $10.4^{\circ}$, $117.8^{\circ}$ to average $22.6^{\circ}$, $113.5^{\circ}$ immediate postoperatively, and had maintained to average $21.2^{\circ}$ and $114.4^{\circ}$ at the last follow-up. The degree of articular surface depression had improved significantly from preoperative average 4.8 mm to 1.5 mm at the last follow-up. All cases achieved bone union, and the interval to union was average 12.8 weeks. AOFAS score was average 85.2 points at last follow-up. There were 7 excellent, 10 good, and 3 fair results according to the CNHF scale. Therefore, 17 cases (85%) achieved satisfactory results. Conclusion: Plate fixation using porous hydroxyapatite seems to be one of effective treatment methods for intraarticular calcaneal fracture of joint depression type, because of supporting the reduction of subtalar articulation by augmenting bony defect and facilitating bone formation. Further evaluation about long-term radiological changes and histological analysis on hydroxyapatite implantation site should be required.

LiDAR has been one of the widely used and important technologies for 3D modeling of ground surface and objects because of its ability to provide dense and accurate range measurement. The objective of this research is to develop a method for automatic detection and modeling of railroad power lines using high density LiDAR data and RANSAC algorithms. For detecting railroad power lines, multi-echoes properties of laser data and shape knowledge of railroad power lines were employed. Cuboid analysis for detecting seed line segments, tracking lines, connecting and labeling are the main processes. For modeling railroad power lines, iterative RANSAC and least square adjustment were carried out to estimate the lines parameters. The validation of the result is very challenging due to the difficulties in determining the actual references on the ground surface. Standard deviations of 8cm and 5cm for x-y and z coordinates, respectively are satisfactory outcomes. In case of completeness, the result of visual inspection shows that all the lines are detected and modeled well as compare with the original point clouds. The overall processes are fully automated and the methods manage any state of railroad wires efficiently.

Background: Nefopam is a non-opioid, non-steroidal, centrally acting analgesic drug. The concomitant use of opioids and nefopam is believed to have many advantages over the administration of opioids alone for postoperative pain management. We conducted a randomized, double-blind study to determine the fentanyl-sparing effect of co-administration of nefopam with fentanyl for postoperative pain management via patient controlled analgesia (PCA). Methods: Ninety female patients who underwent laparoscopic total hysterectomy under general anesthesia were randomized into 3 groups, Group A, fentanyl $1,000{\mu}g$; Group B, fentanyl $500{\mu}g$ + nefopam 200 mg; and Group C, fentanyl $500{\mu}g$ + nefopam 400 mg, in a total volume of 100 ml PCA to be administered over the first 48 h postoperatively without basal infusion. The primary outcome was total fentanyl consumption during 48 h; secondary outcomes included pain scores and incidence of side effects. Results: Eighty-one patients were included in the analysis. The overall fentanyl-sparing effects of PCA with concomitant administration of nefopam during the first 48 h postoperatively were 54.5% in Group B and 48.9% group C. Fentanyl use was not significantly different between Groups B and C despite the difference in the nefopam dose. There were no differences among the three groups in terms of PCA-related side effects, although the overall sedation score of Group B was significantly lower than that of Group A. Conclusions: The concomitant administration of nefopam with fentanyl for postoperative pain management may allow reduction of fentanyl dose, thereby reducing the risk of opioid-related adverse effects.

The purpose of this study was to analyze the content and design of the seven math camp programs for students of the education centers for the elementary gifted students. The analysis focused on the goals, content, and evaluations utilized in the math camp programs. The results of the study were as follows. First, there was no big difference between the goals set for each camp, and they mainly focused on the goals in affective domain. Second, the content of math camp programs was focused on enrichment rather than acceleration. Most of the programs were focused on geometry, whereas fewer programs were focused on measurement, probability and statistics. Based on the Analysis, we found that only nine out of 27 programs applied level-wised or individual exercise programs. Third, all centers for the mathematically gifted carried out evaluations of their math camp programs. However, a specific evaluation plan was not established for the math camp program plans. We suggested the direction of math camp programs as follows. First, the goals should reflect on the intended outcomes of the math camp programs. Also, the goals of math camp programs need to be distinctive from general education goals. Second, the programs should contain harmonious contents with enrichment and acceleration and must include various reactions and task commitment. The math camp programs need to include references and an appropriate information for the gifted students to encourage self-directed learning. Third, a more specific evaluation plan for math camp programs needs to be developed for effective education for the gifted students.

The assessment of patient status in palliative medicine is essential for determining treatments and for clinical outcomes. The objective of assessment tools is to raise the quality of care for individual patients and their families. There are a number of tools available to assess pain, non-pain symptoms and quality of life. The tools are either uni-dimensional or multi-dimensional measures. Unfortunately, however, no single tool is recommended to be a superior to others in symptoms or quality of life assessment. Therefore, to select an appropriate assessment tool, one should consider the time frame and unique characteristics of tools depending on purpose and setting. The combination of prognostic index is highly recommended in prognostication, and web-based prognostic tools are available. Recently, a new objective prognostic score has been constructed through multicenter study in Korea. It does not include clinicalestimates of survival, but includes new objective prognostic factors, therefore, anyone can easily use it. For beginners in palliative medicine, relatively easy-to-use tools would be convenient. We recommend Eastern Cooperative Oncology Group performance status to assess functional status, numeric rating scale for pain assessment and the Korean version of brief pain inventory for initial pain assessment. Asking directly with numeric rating scale or the Korean version of MD Anderson Symptom Inventory would be desirable to assess various symptoms together. We think that European Organization Research and Treatment Quality of Life Questionnaire Core 15 for Palliative Care is good to assess the quality of life, while Objective Prognostic Score is convenient as prognostic index for beginners.

Background: The purpose of this study was to evaluate whether measuring the ratio of descending aortic enhancement (DAE) to main pulmonary artery enhancement (MPAE) on pulmonary computed tomography angiography (PCTA) can predict poor outcome in patients with acute massive or submassive pulmonary embolism (PE). Methods: We retrospectively, reviewed computed tomgraphy findings and charts of 37 patients with acute PE and right ventricular dysfunction. We divided the enrolled patients into 3 groups; group Ia (n=8), comprised of patients with major adverse event (MAE); group Ib (n=5), consisted of those with PE-related MAE; and group II (n=29), those without MAE. We analyzed the right ventricular diameter (RVD)/left ventricular diameter (LVD) and DAE/MPAE on PCTA. Results: For observer 1, RVD/LVD in group Ia ($1.9{\pm}0.36$ vs. $1.44{\pm}0.38$, p=0.009) and group Ib ($1.87{\pm}0.37$ vs. $1.44{\pm}0.38$, p=0.044) were significantly higher than that of group II. For observer 2, RVD/LVD in group Ia ($1.71{\pm}0.18$ vs. $1.41{\pm}0.47$, p=0.027) was significantly greater than that of group II, but RVD/LVD of group Ib was not ($1.68{\pm}0.2$ vs. $1.41{\pm}0.47$, p=0.093). For both observers, there was a significant difference of DAE/MPAE between group Ib and group II ($0.32{\pm}0.15$ vs. $0.64{\pm}0.24$, p=0.005; $0.34{\pm}0.16$ vs. $0.64{\pm}0.22$, p=0.004), but no significant difference of DAE/MPAE between group Ia and group II ($0.51{\pm}0.3$ vs. $0.64{\pm}0.24$, p=0.268; $0.53{\pm}0.29$ vs. $0.64{\pm}0.22$, p=0.302). Intra-class correlation coefficient (ICC) for the measurement of DAE/MPAE (ICC=0.97) was higher than that of RVD/LVD (ICC=0.74). Conclusion: DAE/MPAE measured on PCTA may predict PE-related poor outcomes in patients with massive or submassive PE with an excellent inter-observer agreement.

Purpose: This study was performed to evaluate the clinical outcomes of operative treatment using mini-open sinus tarsi approach for displaced intraarticular calcaneal fractures. Materials and Methods: We studied 18 cases (16 patients) of intraarticular calcaneal fractures who were treated with sinus tarsi approach by same surgeon. The mean age of patients was 44.8 years, and mean follow-up period was 17.2 months. The measurement of B$\ddot{o}$hler angle, Gissane angle, the degree of articular surface depression, and the period to union were performed through preoperative and postoperative radiographs. The clinical evaluation was performed according to hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) and scale of the Creighton-Nebraska health foundation (CNHF). Results: B$\ddot{o}$hler angle and Gissane angle had improved significantly from preoperative average $9.8^{\circ}$, $117.6^{\circ}$to average $22.4^{\circ}$, $113.4^{\circ}$ immediate postoperatively, and had maintained to average $21.8^{\circ}$and $114.2^{\circ}$ at the last follow-up. The degree of articular surface depression had improved significantly from preoperative average 5.2 mm to 1.2 mm at the last follow-up. All cases achieved bone union, and the period to union was average 10.5 weeks. AOFAS score was average 86.2 points at the last follow-up. There were 7 excellent, 9 good, and 2 fair results according to the CNHF scale. Therefore, 16 cases (88.8%) achieved satisfactory results. Conclusion: The minimally invasive sinus tarsi approach using headless compression screw seems to be an effective surgical method for displaced intraarticular calcaneal fractures, because of the possibility of accurate restoration of articular surface and the low risk of postoperative soft tissue complications.
