  • Background: Reverse total shoulder arthroplasty (rTSA) has gained popularity in recent years and is indicated for a wide variety of shoulder pathologies. However, use of rTSA in patients with "weight-bearing" shoulders that support wheelchair use or crutches has higher risk. The aim of this study was to assess the results of rTSA in such patients. Methods: Between 2005 and 2014, 24 patients (30 shoulders) with weight-bearing shoulders were treated with rTSA at our unit. Patients had cuff arthropathy (n=21), rheumatoid arthritis (n=3), osteoarthritis (n=1), acute fracture (n=3), or fracture sequela (n=2). Postoperatively, patients were advised not to push themselves up and out of their wheelchair for 6 weeks. This study was performed in 2016, and 21 patients (27 shoulders) were available for a mean follow-up of 5.6 years (range, 2-10 years). The mean age at surgery was 78 years (range, 54-90 years). Results: Constant-Murley score improved from 9.4 preoperatively to 59.8 at the final follow-up (P=0.001). Pain score improved from 2/15 to 13.8/15 (P=0.001). Patient satisfaction (Subjective Shoulder Value) improved from 0.6/10 to 8.7/10 (P=0.001). Significant improvement in mean range of motion from 46° to 130° of elevation, 14° to 35° of external rotation, and 29° to 78° internal rotation was recorded (P=0.001). Final mean Activities of Daily Living External and Internal Rotation was 32.4/36. Only three patients showed Sirveaux-Nerot grade-1 (10%) glenoid notching and three grade 2 (10%). Conclusions: rTSA can be used for treatment of patients with weight-bearing shoulders. Such patients reported pain free movement, resumed daily activities, and high satisfaction rates.

  • The purpose of the study was to examine the effects of initial body weight and synbiotics supplementation in the diet on growth performance of weaned pigs. A total of 80 crossbred pigs (Landrace×Yorkshire×Duroc, d 28±3, body weight 6.40±1.70 kg) were randomly distributed 4 treatments (4 replication, 5 pigs/replication). The treatments were 1) high initial body weight group (PC), 2) low initional body weight group (NC), 3) low initial body weight with 0.2% antibiotics (amoxicillin) supplementaion group (AB), 4) low initial body weight with 0.2% synbiotics (AllTech® Bio-Mos 0.3%, 0.3%, Bacillus subtillis 0.1%, formic acid 0.1%) supplementation group (Syn). AllTech® Bio-Mos is consist of at least 25% of glucomannanprotein extracted from the cell wall of Saccaromycess cerevisae. Growth performance was measured during 28 d. Average daily gain (ADG) of AB and Syn groups were significantly (p<0.05) higher than that of NC group. However, final body weight at the end of experiment were not different among NC, AB, and Syn groups. Initial body weight and final body weight of PC group were statistically (p<0.001) higher compared to those of other groups. Additionally, PC showed the tendency of lower average daily feed intake and higher ADG, thereby lower feed conversion ratio compared with other groups. Therefore, the current results imply that supplementation of antibiotics and synbiotics in diets for weaned pigs could not catch up with significant differences in initial body weight.

  • In this paper, multiphase dynamic optimization of machine structure is presented. The final goal is to obtain ( i ) light weight, and ( ii ) rigidity statically and dynamically. The entire optimization process is carried out in two steps. In the first step, multiple optimization problem with two objective functions is treated using Pareto genetic algorithm. Two objective functions are weight of the structure, and static compliance. In the second step, maximum receptance is minimized using genetic algorithm. The method is applied to a simplified milling machine.

  • The design of seat is maintaining to final stable posture. The final stable posture is the seated posture in which the force of the pad and spring supporting the body is balanced with the body weight and the bodydoes not sink anyfurther intothe seat. With poorly designed seated seats, your behind maygradually move forward, or localized pressure may result in congestion of the blood or numbness, making you want to move. Therefore, the final stable posture is not maintained. A number of ideas were used in this study will eliminate this problem. In automobile seat design, primary attention has forcused on providing the occupant with a comfortable seat that has sufficient padding and adjuxtments toaccomodate different sizes and postures of people. First of all, whether the process is design-oriented or technology-oriented, the design concept must be human-oriented. The fatigue-alleviating seats which were the primary purpose of this research were studied with a human-oriented approach.

  • Lovastatin is a cholesterol-lowering agent, which plays a role of an inhibitor of 3-hydroxy-3- methylglutaryl coenzyme A reductase (HMG-CoA). When thiamine was supplemented in 3L batch fermentation, the production of lovastatin was improved. At the same time, the levels of pyruvic acid and NAD(P)H were estimated in the course of the fermentation of A. terreus. For the high level production of lovastatin, semi fed-batch fermentation was performed. And the thiamine level was maintained to a concentration of 20 mg/L and glucose was supplied. The final dry cell weight was lowered by 30 % and final lovastatin concentration was increased by 33 %. Final lovastatin concentration of 3.3 g/L was achieved in 8 days.

  • The purpose of this study was to analyze body image of women and investigate the relationships of apparel management behavior and weight(figure) control behavior. To achieve the purposes, a questionnaire was conducted to 329 females from October 5 to October 25, 2011. The final data were analyzed with spss 17.0 program. The results were as follows. First, It was found that body image were classified 4 factors of care for appearance, concern about weight, effort of appearance improvement. and appearance attractiveness. Second, there were significant differences of body image by demographic characteristics. Third, there were significant differences of BMI, apparel management behavior and weight(figure) control behavior by demographic characteristics. Forth, there were significant differences of body image, apparel management behavior and weight(figure) control behavior by BMI. Fifth, there were partial significant relations of body image, BMI, appearance management behavior and weight(figure) control behavior. Thus, it was found that body image is related to appearance management behavior and weight(figure) control behavior.

  • A trial with twenty-four newly weaned Awassi lambs (initial body weight=21.5$\pm$0.8 kg) was conducted using a 3$\times$2 factorial design to study the effect of feeding three sources of protein supplements (soybean meal (SBM), sunflower seed meal (SSM), and cottonseed meal (CSM)), either untreated or formaldehyde-treated on the growth performance and carcass traits of Awassi lambs. Lambs were randomly assigned to one of the six diets (4 lambs/treatment diet) and were individually fed for a period of 107 days. Experimental diets were isonitrogenous and isocaloric. Final live weight and average daily gain (ADG) were affected by both source of protein and formaldehyde treatment (undegradable protein). Lambs fed untreated diets had better (p<0.01) daily gain compared to those fed formaldehyde-treated diets. Similarly total feed intake per animal was significantly (p<0.05) affected by protein source and formaldehyde treatment. Formaldehyde treatment caused a significant decrease (p<0.01) in feed intake compared to lambs fed untreated diets. Feed requirement per unit of gain was not affected by formaldehyde treatment during all periods of the experiment except for the second period (the second 28 day period), whereby untreated SBM, SSM and CSM had better feed conversion ratio (FCR) than the treated groups. Source of protein had a moderate effect (p<0.10) on FCR but had a significant effect (p<0.05) on hot and cold carcass weight, digestive tract empty weight and liver weight, with lambs fed SBM having higher values than lambs fed SSM and CSM diets. Supplementation with undegradable protein had a significant effect (p<0.05) on dressing-out percentage (p<0.05), final live weight, and hot and cold carcass weight (p<0.01). The lower values pertain to lambs fed treated diets compared to lambs fed untreated diets. In general, there were no significant differences among all carcass linear dimensions, carcass cut weights and dissected loin tissue weights for both treatments (protein source and formaldehyde treatment). Supplementation with undegradable protein but not the source of protein resulted in significantly higher dissected leg total bone weight (p<0.05), tibia and femur weight (p<0.05), and femur length (p<0.01) at the same carcass weight. Results suggest that the treatment of SBM, SSM and CSM with formaldehyde did not improve efficiency of feed utilization, lamb performance or carcass traits and that the SBM diet resulted in an increase in lamb performance compared to other experimental diets.

  • Neural networks have been reborn as a Deep Learning thanks to big data, improved processor, and some modification of training methods. Neural networks used to initialize weights in a stupid way, and to choose wrong type activation functions of non-linearity. Weight initialization contributes as a significant factor on the final quality of a network as well as its convergence rate. This paper discusses different approaches to weight initialization. MNIST dataset is used for experiments for comparing their results to find out the best technique that can be employed to achieve higher accuracy in relatively lower duration.

  • Purpose: The purpose was to develop a preliminary scale to measure Korean adolescents' health behaviors through a qualitative approach, to evaluate the scale psychometrically, and to develop a final scale. Methods: Participants were 61 adolescents for qualitative interviews and 1,687 adolescents for the psychometric evaluation. Procedure included content analysis of interviews to identify health behavior categories for Korean adolescents, pre-test to confirm that preliminary scale items were understandable, content validity by an expert panel, development of the web-based computer-assisted survey (CAS), and psychometric analysis to determine reliability and validity of the final scale. Results: A final scale was developed for both paper-and-pencil and CAS. It consisted of 14 health behaviors (72 items), including stress and mental health (10), sleep habits (5), dietary habits (12), weight control (4), physical activity (4), hygiene habits (5), tobacco use (5), substance use (2), alcohol consumption (4), safety (4), sexual behavior (9), computer use (3), health screening (4), and posture (1). Conclusion: The scale's strong points are: 1) Two thirds of the final scale items are Likert scale items, enabling calculation of a health behavior score. 2) The scale is appropriate to Korean culture. 3) The scale focuses on concrete health behaviors, not abstract concepts.
