Femur is the largest bone in the human body which supports the weight of body. A long pipeline shape of femur has little cancellous bone, so that regeneration is difficult when fracture happens. The fracture caused by an accident most frequently occurs at diaphysis. IM Nailing is the surgical method that implants an IM Nail into a medullary cavity for the fixation of fracture parts. However, a secondary fracture may happen if an IM Nail does not penetrate at the center of femur. In this study, a patient-specific femur was manufactured by a 3D printer using the computed tomography images scanned before surgery, which was used for the simulation of IM Nailing. It is expected that this result may prevent the secondary damage, reduce surgical operation time, and increase the precision.

Soil nailing method is widely used in reinforcing slopes and excavating earth. The analysis of nail-reinforced slopes, generally require complicated computer programs. The purpose of this paper is suggest, Soil stability Chart for nailed slopes which are very useful for pre-design, rapidly design, and final check. Three slope types, three nail lengths and three nail angles are selected for the stability analysis by using limit equilibrium method form Bishop and French. From the above results, this study propose the reinforced design charts for examine the necessity of reinforcement can be examined. The suggested stability chart and Taylor's Slope Stability Chart, showed similar safety factors. This Soil Nailing design charts can provide the solutions for necessity of reinforcement, economical of nail's length ratio and installation angle as well.

Biometrics is getting more and more attention in recent years for security and other concerns. So far, only fingerprint recognition has seen limited success for on-line security check, since other biometrics verification and identification systems require more complicated and expensive acquisition interfaces and recognition processes. Hand-Geometry has been used for biometric verification and identification because of its acquisition convenience and good performance for verification and identification performance. Hence, it can be a good candidate for online checks. Therefore, this paper proposes a Hand-Geometry recognition system based on geometrical features of hand. From anatomical point of view, human hand can be characterized by its length, width, thickness, geometrical composition, shapes of the palm, and shape and geometry of the fingers. This paper proposes thirty relevant features for a Hand-Geometry recognition system. However, during experimentation, it was discovered that length measured from the tip of the finger was not a reliable feature. Hence, we propose a new technique based on Genetic Algorithm for extraction of the center of nail bottom, in order to use it for the length feature.

The analysis for stability of slope reinforced with soil nails need professional knowledge and skilled technology for program. So we spend a lot of money and time. In this study, we try to save it. After we analyzed the stability of reinforced slope with MIDAS GTS using shear strength reduction technique, we made charts by result. Charts created in the stydy can be used rapidly in slope disaster prevention. We try to analyze stability of slopes when we changed nail spacing, nail angle, slope type, properties of soil. We obtained relationship as follows; 1) The safety factor appears effectively when the nail angle is $10{\sim}20^{\circ}$. 2) The safety factor appears effectively when the nail spacing is 0.8~1.2m. 3) The error of Singh's and suggested chart are 3.45, 8.65, 4.35% when the slope are 1:0.5, 1:1, 1:2.

Background: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. Methods: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. Results: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. Conclusions: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.

From 1988 to 1997, we experienced 11 cases of glomus tumor in fingers(10 cases) and toe(1 case). All patients were female, and showed typical pain, tenderness, and cold sensitivity of the lesions. The locations were subungal in nine cases and in pulp from distal phalangeal bone in two cases. Three patients had histories of one or two failed previous operations, and two patients had another glomus tumor in their bodies. All except one had satisfactory results subjectively and without complications. One patient was operated by the excision of the tumor including germinal matrix and surrounding tissues of nail bed, and had a nail deformity in follow-up. The glomus tumor is not malignant to recur or metastasize in the case of complete excision. However, the surgeon should be alert not to injure or repair the nail bed meticulously after the excision of the tumor to prevent a late deformity of nail.

0.5mm thick steel is used to manufacture nail files. The first process is blanking and the second process is making about 300 holes of 0.8-l.0mm in diameter. This process depends mainly on etching which takes 33% of manufacturing cost and it can make manufacturing cost rise. The residual etching reagent is not environmentally friendly and the steel material is apt to rust as well. To solve these problems, researches on the following subjects are performed: proper material to prevent from rusting and strip layout strategies in stamping to replace etching process with press process which makes use of die. And new quill type punch is developed to replace the regular standard punch, one of the die parts, which frequently get broken while working. And these researches and developments lead to develop a progressive perforating die.

In this paper, we introduced phase optimization techniques in the Soil-Nail design to optimize the reinforcement required for each grade level. The optimal design results at the maximum slope height were further amplified to allow for phase optimization of the horizontal spacing of the Nail in accordance with the change in the height of the slope. The limit equilibrium analysis was performed by step-by-step sloping height, and the safety factor exceeded when the horizontal spacing of four days was fixed. The process of optimization was effectively carried out by densifying the required reinforcement depending on the slope elevation. Also limited to reflect the axial force of the nail into the reinforcement details.Using the method, the members' strength was reflected. When phase optimization technique is applied for each slope height by calculating the stiffening precision, it is judged that it will be more economical to optimize horizontal intervals by effectively reducing the repeated reinterpretation process that satisfies the reference safety ratio for each slope height.

The nail service field, which has emerged as a new trend in the beauty industry, is showing rapid growth compared to other beauty fields. As nail beauty services become more common and popular, studies on related fields are also actively progressing, but most of the research has been focused on changes on self-esteem. In addition, most of the preceding studies are centered on female customers, thus, there is little data on male customers that are increasing recently. This research aims to provide customized marketing data to the nail beauty service industry by analyzing the psychological characteristics of the customers and their motives by selecting self-esteem and confidence as factors. First, the customers' confidence and self-esteem were classified into a group with high and low confidence and self-esteem, and as a result of analyzing the difference in service pursuit benefits and revisit intentions, there were significant differences in mood change, professionalism, health hygiene, aesthetics, and revisit. Second, as a result of analyzing the effect of the service pursuit benefits of male and female customers on the revisit intention, it was found that only health and hygiene had a significant effect on the revisit intention. Female customers also had a significant influence on their revisit intention, which is judged to have a significant effect on male customers' revisit intention because most of the main management is cuticle cleaning, callus management, and problematic nails.
