Balanced Scorecard menganalisis kinerja organisasi secara keseluruhan melalui empat perspectif. menilai organisasi melalui Financial Return hanya memberikan informasi tentang kinerja organisasi sebelum penilaian, sehingga kinerja masa depan tidak dapat diprediksi dan tidak dapat mengambil strategi maupun tindakan yang tepat untuk Sustainable Development Growth. Penelitian ini mencoba menunjukkan perspektif Balance Scorecard, kemudian analisis SWOT dan dapat ditentukan posisi perusahaan sesuai Internal External Matrix. Objek pada penelitian ini adalah perusahaan sektor perbankan. Metode pengumpulan data pada penelitian ini adalah dengan data primer dan sekunder. Data primer dapat diperoleh melalui wawancara dengan key informan, serta data sekunder didapat melalui dokumentasi data data yang dibutuhkan diperoleh dari PT Bank X. Matrix sesuai dengan SWOT perusahaan, selanjutnya akan dilakukan klarifikasi hasil menggunakan IFE Matrix (Strength Weakness) dan EFE Matrix (Opportunities - Threats). Kedua Matrix yang telah terbentuk tersebut diplot ke dalam Internal External Matrix, dan berada di kuadran I, sehingga dapat diketahui posisi strategik PT Bank X pada posisi Grow and Build. Strategi yang paling tepat berdasarkan posisi Grow and Build adalah dengan menerapkan Intensive Strategy yang spesifik strateginya dapat menggunakan strategi pengembangan pasar, dan product development. Berdasarkan analisa BSC dan IE Matrix dihasilkan suatu rekomendasi strategi pada product development, diantaranya melakukan upaya peningkatan kualitas SDM, perbaikan kualitas kredit, serta digitalisasi perbankan dalam mempersiapkan persaingan di era revolusi industri 4.0

For the extrusion of glasses with a conical bottom using the method of plastic flow by A. L. Vorontsov, the kinematic and stress states of the extruded metal in the area of the plastic deformation zone in contact with the conical surface of the matrix were determined. The results are combined with the results obtained earlier for the cylindrical region located under the forming glass wall. The resulting formulas will be used to determine the stress state in the areas of the focus located under the end of the punch. The derived formula for the maximum pressure on the matrix wall is necessary for calculating the matrix strength and making an informed decision about the need for its banding.

This study examined the effect of adding synthetic fibers, that is, polypropylene (PP) and nylon (Ny), on explosive spalling and residual tensile mechanical properties of high-performance fiber-reinforced cementitious composites (HPFRCCs). Three different matrix strengths (100 MPa, 140 MPa, and 180 MPa), four different volume contents of the synthetic fibers (0%, 0.2%, 0.4%, and 0.6%), and three different exposure time (1 h, 2 h, and 3 h) based on the Internatinoal Organization for Standardization (ISO) fire curve were adopted as variables for this experiment. The experimental results revealed that the addition of synthetic fibers improved the resistance to explosive spalling induced by high-temperature, especially when PP and Ny were mixed together. For a higher matrix strength, greater volume content of the synthetic fibers was required to prevent explosive spalling, and higher residual strengths were obtained after the fire tests. An increase in the volume fraction of the synthetic fibers clearly prevented explosive spalling but did not affect the residual tensile strength. In the case of a higher matrix strength, a reduction in the strength ratio was observed with increased exposure time.

Roles of the particle, strengthening, and weakening during deformation of the particle reinforced metal matrix composite, were studied using in situ technique. Composites with three different strengths Al-Cu-Mg alloy matrices reinforced by three sizes SiC particles were manufactured and subjected to in situ tensile testing. Based on in situ observation, damage process, fraction and size distribution of the cracked particles were collected to investigate the behavior of the particle during composite deformation. The presence of the particle strengthens the composite, while the particle cracking under high load weakens the composite. This strengthening to weakening transformation is controlled by the damage process of the particle and decided by the particle strength, size distribution, and the matrix flow behavior together. With a proper match of the particle and matrix, an effective strengthening can be obtained. Finally, the effective match range of the particle and the matrix was defined as a function of the particle size and the matrix strength.

The gold standard treatment for anterior cruciate ligament (ACL) reconstruction is the use of tendon autografts and allografts. Limiting factors for this treatment include donor site morbidity, potential disease transmission, and variable graft quality. To address these limitations, we previously developed an off-the-shelf alternative, a poly(l-lactic) acid (PLLA) bioengineered ACL matrix, and demonstrated its feasibility to regenerate ACL tissue. This study aims to 1) accelerate the rate of regeneration using the bioengineered ACL matrix by supplementation with bone marrow aspirate concentrate (BMAC) and growth factors (BMP-2, FGF-2, and FGF-8) and 2) increase matrix strength retention. Histological evaluation showed robust tissue regeneration in all groups. The presence of cuboidal cells reminiscent of ACL fibroblasts and chondrocytes surrounded by an extracellular matrix rich in anionic macromolecules was up-regulated in the BMAC group. This was not observed in previous studies and is indicative of enhanced regeneration. Additionally, intraarticular treatment with FGF-2 and FGF-8 was found to suppress joint inflammation. To increase matrix strength retention, we incorporated nondegradable fibers, polyethylene terephthalate (PET), into the PLLA bioengineered ACL matrix to fabricate a “tiger graft.” The tiger graft demonstrated the greatest peak loads among the experimental groups and the highest to date in a rabbit model. Moreover, the tiger graft showed superior osteointegration, making it an ideal bioengineered ACL matrix. The results of this study illustrate the beneficial effect bioactive factors and PET incorporation have on ACL regeneration and signal a promising step toward the clinical translation of a functional bioengineered ACL matrix.
