Kinerja Karyawan Ditinjau Dari Lingkungan Kerja dan Motivasi Berpretasi Pada CV. Cendana Megah Santosa Kecamatan Purwodadi Kabupaten Grobogan Tahun 2015

The purpose of this study was to describe: 1) The work environment on employee performance CV. Magnificent Santosa 2015 sandalwood, 2) Achievement motivation on employee performance CV. Magnificent sandalwood Santosa 2015, 3) The work and achievement motivation on employee performance CV. Magnificent Santosa 2015 sandalwood. The method used in this research is descriptive quantitative method. The data in this study was obtained from data from the questionnaire. Data collected by using a filling questionnaires, observation, and documentation. The results showed: 1) The results of multiple linear regression analysis obtained by the working environment of 0.342, 0.245 of achievement motivation, this proves that the work environment variables and achievement motivation have an influence on the performance of employees at the company CV. Magnificent sandalwood Santosa 2015. 2) The results of the t test obtained t count for variable working environment of 2.471 while ttable of 2.006, then Ho is rejected so that there is significant influence among the working environment on the performance of individual employees. 3) The results of the t test obtained t count for the achievement motivation of 2.282 while t table of 2.006, then Ho is rejected so that there is significant relationship between achievement motivation on employee performance is individu.4) F-test analysis results obtained F count = 15.252> Ftabel = 3.23, then Ho is rejected so that together there is significant influence work environment (X1), achievement motivation (X2) on employee performance (Y) .From the results of the analysis of data obtained by the coefficient of determination R2 of 0.379 which indicates that the combination work environment variables and achievement motivation of 37.90%, while 62.10% is influenced by other variables not examined

Histological alterations after irradiation of cartilage using Ho : YAG laser

KORKUSUZ, FEZA/0000-0001-9486-3541WOS: 000180843500002PubMed: 12614553The authors carried out an experimental study to evaluate the histological alterations after irradiation of cartilage using Holmium:YAG (Ho:YAG) laser VersaPulse Select 60 watts and Infra. Tome Delivery Systems 30degrees Handpiece (spot size at fiber tip 0.4 mm; Coherent Medical, Palo Alto, CA). Background Data: Recently, some authors reported cases with articular cartilage damage following arthroscopic laser surgery in the knee joint for the treatment of articular cartilage or meniscal pathology. Materials and Methods: The cartilage specimens immersed in saline were exposed to Ho:YAG laser irradiation. The laser wavelength was 2.1 mum, and pulse duration was 250 musec. Power settings were 0.2-1 joules per pulse and 10-15 Hz. Total laser energy used in these procedures was 1.5 K joules. During the procedures, the handpiece was used at an angle of 30degrees and at a distance of 1 mm. Results: Electron microscopic evaluation demonstrated that the ultrastructure of the cartilage is preserved in both experiment and control groups. Conclusion: When Ho:YAG laser is used in optimal dosage (optimal joule and Hertz) with optimal technique (keeping the handpiece at an appropriate angle and distance) and avoiding overtreatment, it does not cause cartilage damage

Histological and magnetic resonance imaging alterations after irradiation of meniscus using holmium : YAG laser

KORKUSUZ, FEZA/0000-0001-9486-3541WOS: 000172158300004PubMed: 11710619Objective: The authors performed an experimental and a prospective clinical study to evaluate the histological and magnetic resonance imaging (MRI) alterations after irradiation of meniscus using holmium:YAG (Ho:YAG) laser VersaPulse Select 60 watts and InfraTome Delivery Systems 30 degrees Handpiece (spot size at fiber tip 0.4 mm; Coherent Medical, Palo Alto, CA). Background Data: Recently, some authors reported a few cases with articular cartilage damage or paraarticular osteonecrosis following arthroscopic knee surgery in which the laser was used to assist in the treatment of meniscal pathology. Methods: Meniscus specimens in saline immersion were exposed to Ho:YAG laser irradiation. The laser wavelength was 2.1 mum and pulse duration was 250 mu sec. Power settings were 1-1.5 joules per pulse and 10-15 Hz. Total laser energy used in these procedures was 2, 3.5, and 6 K joules. Eight patients with meniscal problems underwent arthroscopic partial meniscectomy using Ho:YAG laser. Total laser energy used for these surgeries was 1.5-2.5 K joules. MRI was performed preoperatively and at 6 months postoperatively. Results: At higher energy levels (more than 3 K joules), separation of the gap between the collagen fibers, and a three-dimensional dispersion in the striation were observed on electron microscopic evaluation of meniscus specimens. No patient had abnormal signals in MRI (a sign of articular cartilage damage or osteonecrosis) following arthroscopic laser surgery. Conclusion: When higher energy level is required, conventional instruments should be preferred in the treatment of meniscal lesions. Laser should be reserved for the posteriorly located and smaller meniscal lesions
