The purpose of this study is to analyze the fusion phenomenon that appears in contemporary women's denim fashion in order to find a way to come up with a creative denim design. The methodology of this study is to research documents related to fusion phenomena and consider precedent studies to establish a criteria for analyzing fusion phenomena. The results are as follows: First, fusion phenomena in modern women's denim can be categorized into fusion of time, fusion of space, fusion of gender, fusion of culture, and fusion of genre. Fusion of time appears as fusion with the past and fusion with the future. Fusion of space appears as fusion with Asia and fusion with other regions. Fusion of gender appears as unisex, androgynous, and genderless. Fusion of culture appears as fusion with subcultures such as grunge, kidult, lingerie, hippy look, hip hop fashion, etc. Finally, fusion of genre appears as fusion of materials, fusion of style, and fusion of circumstances. Second, when analyzing the frequency of appearance for fusion phenomena, fusion of culture appeared with a frequency of 29.7%, followed by fusion of genre with 19.1%, fusion of time with 10.5%, fusion of gender with 9.9%, and fusion of space with 8.5%. When analyzing the most frequently appearing fusion phenomena by year, fusion of culture appeared the most from the year 2000 to 2004, fusion of space and time in 2005, fusion of genre from 2006 to 2007, fusion of culture again in 2008 and 2009, and once more fusion of genre appeared the most in 2010.

In order to facilitate the process of designing a fusion curriculum, this study used the learning outcomes presented in KEC2015 to design a fusion goal dimension. The three dimensions of fusion education in the fusion curriculum framework are fusion goals, fusion approach and fusion context. As a result of examining the curriculum learning activities in order to confirm that the developed curriculum meets these three dimensions, it can be confirmed that it contributes relatively evenly to the fusion goal, fusion approach and fusion context dimension. In addition, it provides a procedure to develop the fusion curriculum through the concrete procedures and examples from the design to implementation of the developed fusion curriculum, and to confirm the result of the fusion dimension.

Envelope proteins of virus contain a segment of hydrophobic amino acids, called as fusion peptide, which triggers membrane fusion by insertion into membrane and perturbation of lipid bilayer structure. Potential fusion peptide sequences have been identified in the middle of L or M proteins or at the N-terminus of S protein in the envelope of human hepatitis B virus (HBV). Two 16-mer peptides representing the N-terminal fusion peptide of the S protein and the internal fusion peptide in L protein were synthesized, and their membrane disrupting activities were characterized. The internal fusion peptide in L protein showed higher activity of liposome leakage and hemolysis of human red blood cells than the N-terminal fusion peptide of S protein. Also, the membrane disrupting activity of the extracellular domain of L protein significantly increased when the internal fusion peptide region was exposed to N-terminus by the treatment of V8 protease. These results indicate that the internal fusion peptide region of L protein could activate membrane fusion when it is exposed by proteolysis.

Butt fusions were practiced with butt fusion in the various conditions of fusion temperatures, pressure and time, and the tests of tesile strength, breaking water pressure and fusion features were also practiced so that the reliability of the butt fusion and the fittets fusion condition may be closely examined. And the width, height and thickness of the beads were also closely measured. The fittest fusion result was achieved in the condition of the temperature of $210^{\circ}C$, heating time hight pressure of 14 seconds on the pressure of $1.5kg/cm^2$, heating time hight pressure of 100 seconds and pressure buid-up time of 11 seconds. And in case of the temperature of $250^{\circ}C$, the fittest fusion result was showed in the condition of the heating time hight pressure of 3 seconds on the pressure of 1.0$kg/cm^2$, the heating time low pressure variable of 100 seconds. heating time hight pressure of 14 seconds and the heating maintenance of around 60 seconds. The result of breaking water pressure test of a test piece fusion in the fittest fusion condition was that the fusion condition of the PE pipe showed a good stability and hight reliance. Through this test, it is proved that the temperature of fusion PE pipes can be increased to $250^{\circ}C$ from $210^{\circ}C$. And it can be expected that the above fusion method greatly helps to reduce the fusion time.

Objective : To identify and investigate differences in spinal fusion between the normal and osteopenic spine in a rat model. Methods : Female Sprague Dawley rats underwent either an ovariectomy (OVX) or sham operation and were randomized into two groups: non-OVX group and OVX group. Eight weeks after OVX, unilateral lumbar spinal fusion was performed using autologous iliac bone. Bone density (BD) was measured 2 days and 8 weeks after fusion surgery. Microcomputed tomography was used to evaluate the process of bone fusion every two weeks for 8 weeks after fusion surgery. The fusion rate, fusion process, and bone volume parameters of fusion bed were compared between the two groups. Results : BD was significantly higher in the non-OVX group than in the OVX group 2 days and 8 weeks after fusion surgery. The fusion rate in the non-OVX group was higher than that in the OVX group 8 weeks after surgery (p=0.044). The bony connection of bone fragments with transverse processes and bone formation between transverse processes in non-OVX group were significantly superior to those of OVX group from 6 weeks after fusion surgery. The compactness and bone maturation of fusion bed in non-OVX were prominent compared with the non-OVX group. Conclusion : The fusion rate in OVX group was inferior to non-OVX group at late stage after fusion surgery. Bone maturation of fusion bed in the OVX group was inferior compared with the non-OVX group. Fusion enhancement strategies at early stage may be needed to patients with osteoporosis who need spine fusion surgery.

The demineralized bone matrix (DBM) as the bone graft material to increase the fusion rate was widely used in spinal fusion. The current study aimed to compare the fusion rate of DBM to the fusion rate of autograft in lumbar spine fusion via meta-analysis of published literature. After systematic search, comparative studies were selected according to eligibility criteria. Checklist (risk of bias assessment tool for non-randomized study) was used to evaluate the risk of bias of the included nonrandomized controlled studies. The corresponding 95% confidence interval (95% CI) were calculated. We also used subgroup analysis to analyze the fusion rate of posterolateral lumbar fusion and lumbar interbody fusion. Eight studies were finally included in this meta-analysis. These eight studies included 581 patients. Among them, 337 patients underwent spinal fusion surgery using DBM (DBM group) and 204 patients underwent spinal fusion surgery with mainly autologous bone and without using DBM (control group). There was no significant differences of fusion rate between the two groups in posterolateral fusion analysis (risk ratio [RR], 1.03; 95% CI, 0.90-1.17; p=0.66) and interbody fusion analysis (RR, 1.13; 95% CI, 0.91-1.39; p=0.27). Based on the available evidence, the use of DBM with autograft in posterolateral lumbar spine fusion and lumbar interbody fusion showed a slightly higher fusion rate than that of autograft alone; however, there was no statistically different between two groups.

Currently, most biometrics system authenticates users by using single biometric information. This method has many problems such as noise problem, sensitivity to data, spoofing, a limitation of recognition rate. One method to solve this problems is to use multi biometric information. The multi biometric authentication system performs information fusion for each biometric information to generate new information, and then uses the new information to authenticate the user. Among information fusion methods, a score-level fusion method is widely used. However, there is a problem that a normalization operation is required, and even if data is same, the recognition rate varies depending on the normalization method. A rank-level fusion method that does not require normalization is proposed. However, a existing rank-level fusion methods have lower recognition rate than score-level fusion methods. To solve this problem, we propose a rank-level fusion method with higher recognition rate than a score-level fusion method using correlation coefficient. The experiment compares recognition rate of a existing rank-level fusion methods with the recognition rate of proposed method using iris information(CASIA V3) and face information(FERET V1). We also compare with score-level fusion methods. As a result, the recognition rate improve from about 0.3% to 3.3%.
