Purpose: This pilot study assessed changes in the growth plate and growth rates in children during a 6-month period. Methods: The study included 31 healthy children (17 boys, 14 girls) under evaluation for growth retardation. Height, weight, bone age, insulin like growth factor-1 (IGF-1), and insulin like growth factor binding protein 3 (IGF-BP3) were measured at baseline and after 6 months. In addition, the diameter, thickness, and volume of the femoral and tibial growth plates were measured using magnetic resonance imaging. Results: The mean bone age in boys and girls was 11.7 and 10.7 years, respectively. In boys, height (z score) (-0.2 vs. 0.0), weight (z score) (0.8 vs. 1.1), body mass index (BMI) (z score) (1.27 vs. 1.5), IGF-1 (ng/mL) (343.6 vs. 501.8), and IGF-BP3 (ng/mL) (5,088.5 vs. 5,620.0) were significantly higher after 6 months. In girls, height (z score) (-1.0 vs. -0.7), weight (z score) (-0.5 vs. 0.1), BMI (z score) (-0.02 vs. 0.3), IGF-1 (ng/mL) (329.3 vs. 524.6), and IGF-BP3 (ng/mL) (4,644.4 vs. 5,593.6) were also significantly higher after 6 months. In both sexes, the mean diameter and volume of the femoral and tibial growth plates were significantly increased 6 months later. Conclusion: No significant correlation was found between changes in the growth plate and clinical parameters in children with growth retardation in this study, other than correlations of change in femoral diameter with weight and BMI. A larger, long-term study is needed to precisely evaluate the correlation between change in the growth plate and growth.

The imbalance between reactive oxygen species (ROS) production and total antioxidant capacity (TAC) in seminal fluid indicates oxidative stress and is correlated with male infertility. A composite ROS-TAC score may be more strongly correlated with infertility than ROS or TAC alone. We measured ROS, TAC, and ROS-TAC scores in semen from 127 patients and 24 healthy controls. Of the patients, 56 had varicocele, eight had varicocele with prostatitis, 35 had vasectomy reversals, and 28 had Idiopathic infertility. ROS levels were higher among infertile men, especially those with varicocele with prostatitis (mean ${\pm}$ SE, 3.25 ${\pm}$ 0.89) and vasectomy reversals (2.65 ${\pm}$ 1.01). All infertility groups had significantly lower ROS-TAC scores than control. ROS-TAC score identified 80% of patients and was significantly better than ROS at identifying varicocele and idiopathic infertility. The 13 patients whose partners later achieved pregnancies had a mean ROS-TAC score of 47.7 ${\pm}$ 13.2, similar to controls but significantly higher than the 39 patients who remained infertile (35.8 ${\pm}$ 15.0; P < 0.01). ROS-TAC score is a novel measure of oxidative stress and Is superior to ROS or TAC alone in discriminating between fertile and infertile men. Infertile men with male factor or idiopathic diagnoses had significantly lower ROS-TAC scores than controls, and men with male factor diagnoses that eventually were able to initiate a successful pregnancy had significantly higher ROS-TAC scores than those who failed.

Purpose: This study aimed to analyze the incidence and risk factors of complications following gastric cancer surgery in Korea and to compare the correlation between hospital complications based on the annual number of gastrectomies performed. Materials and Methods: A retrospective analysis was conducted using data from 12,244 patients from 64 Korean institutions. Complications were classified using the Clavien-Dindo classification (CDC). Univariate and multivariate analyses were performed to identify the risk factors for severe complications. Results: Postoperative complications occurred in 14% of the patients, severe complications (CDC IIIa or higher) in 4.9%, and postoperative death in 0.2%. The study found that age, stage, American Society of Anesthesiologists (ASA) score, Eastern Cooperative Oncology Group (ECOG) score, hospital stay, approach methods, and extent of gastric resection showed statistically significant differences depending on hospital volumes (P<0.05). In the univariate analysis, patient age, comorbidity, ASA score, ECOG score, approach methods, extent of gastric resection, tumor-node-metastasis (TNM) stage, and hospital volume were significant risk factors for severe complications. However, only age, sex, ASA score, ECOG score, extent of gastric resection, and TNM stage were statistically significant in the multivariate analysis (P<0.05). Hospital volume was not a significant risk factor in the multivariate analysis (P=0.152). Conclusions: Hospital volume was not a significant risk factor for complications after gastric cancer surgery. The differences in the frequencies of complications based on hospital volumes may be attributed to larger hospitals treating patients with younger age, lower ASA scores, better general conditions, and earlier TNM stages.

In this paper, same parts of a domestic automobiles and foreign automobiles are disassembled fur the evaluation of disassemblability, especially door trim and bumper. Influencing factors of disassembly are determined by the classification of bottleneck process in disassembly process. On the bases of disassembly sequence and structure of parts and subassembly, disassemblability is classified into aye categories. The influencing factors, which are related with the five categories are determined. By these relations, the checklist for disassembly evaluation is draw up and score tables of checked factors are established. For the establishing the disassembly score tables, the weighting values of each five categories are calculated by the disassembly test of automobiles and then, the weighting values of each influencing factors of five categories are calculated by the method of AHP (Analytic Hierarchy Process). And the last, the weighting values are modified and recalculated from the disassembly test. Using these weighting values, the score of influencing factors are determined and then, the score tables are established based on the score of influencing factors.

Dietary therapy is a basic and emphasized treatment for diabetes. Several clinical studies have shown that diet can play a major role in preventing and managing diabetes. The purposes of this study were to evaluate the dietary behavior and to find solutions to barriers of diabetes mellitus patients. From February to July in 2007, questionnaires were distributed to one hundred and ten patients who were diagnosed DM by physicians and excluded first coming out-patients. One hundred and three data were used for statistical analysis using SPSS/Win 12.0. The main results of this study included the following: To measure dietary behaviors and barriers, a five point scale was used with the following labels: 'strongly yes', 'yes', 'fair', 'no', 'strongly no'. Thirteen dietary behaviors related to diabetes were grouped into the following 4 factors using factor analysis; 'taste control factor', 'blood glucose influence factor', 'practice volition factor', and 'exercise factor'. The mean scores of 4 factors were 3.88, 3.48, 3.55, 3.21, respectively. The 'taste control behaviors' score of subjects who had practiced diet therapy(4.00) was higher than those who had not practiced diet therapy(P<0.05). The 'blood glucose influence behaviors' score of subjects who had nutrition education(3.59) was higher than those who had no nutrition education(P<0.05) and subjects who had practiced diet therapy showed higher score(3.59) than those who had not practiced diet therapy(P<0.05). 'Exercise behaviors score' of subjects who were over 60(3.59) was the lowest(P<0.05). Subjects who had nutrition education showed higher 'exercise behaviors' scores(3.38) than those who had no nutrition education(P<0.05). Subjects who had practiced diet therapy showed higher 'practice volition behaviors' scores(3.72) than those who had not practiced diet therapy(P<0.001). Subjects who were over weight showed the highest 'practice volition behaviors' scores(3.78) concerning BMI(P<0.05). In conclusion, this study expected that Nutrition educators(Dietitian) applied to patient effective nutrition education and counseling through evaluation of Dietary behaviors and barriers considered management types and ecological factors of diabetes patients. Also diabetic patients were easy to change dietary habits because they formed behaviors through education and counsel and there were positive effects in their blood glucose control through removing barriers related to dietary therapy.

Purpose : To collect and interpret basic data involving the discomfort level of platelet donors and to see which nursing interventions would help make plateletpheresis more comfortable. Methods : Using "the Platelet Donor's Discomfort Scale" developed by the researcher herself and reviewed by an expert panel, the severity of discomfort as well as factors contributing to the development of this discomfort were analyzed. This scale contained 59 items and each item was scored by the 4-point Likert manner. Between March 1, 1996 and May 31, 1996, 500 platelet donors(16 years of age and older) were enrolled in this study. The Statistical methods used were factor analysis, t-test, and ANOVA. The results were as follows : 1. The mean of the platelet donor's discomfort scale was 130, range 69-207, possible score ranging from 59-236. 2. The platelet donor's discomfort scale had psychological, environmental, physical, and time-related factors. The time- related factor was the highest positive correlation with the development of the discomfort. 3. In looking at the psychological and environmental factors of the discomfort scores, the 16-20 age group had significantly higher ratings than those of the 26-30 age group. The students' group had higher scores than the soldier's group, and those who used the V-50, MCS -3P, or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively), 4. In relation to the physical factor of the discomfort score, the youngest group felt significantly more discomfort, the student's group had a higher score than the soldier's group, and those who used the V-50, MCS-3P, or or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively). 5. The time related factor of the discomfort score had the highest scores in every variable, however, statistically significant differences were not found between any of the variables(P>.05). Conclusion : Based on the above results, it can be oserved that the time-related factor was the most important factor influencing discomfort. The age and job of the donor, as well as the type of machine used, were significant variables in predicting the level of discomfort, regardless of psychological, environmental, and physical factors. This data could be used to determine nursing interventions that would relieve some of the discomfort of patients, as well as donors, undergoing plateletpheresis. Furthermore, consideration of the donor's time, introduction of a platelet donor pool system, publicity and education about platelet donation are required.
