Purposes: The study aimed to translate the Exercise Self-Efficacy Scale (ESES) into Indonesian and test the cultural equivalence, reliability, and validity of the new version for university students. Methods: The cross-sectional study recruited 379 Indonesian university students using convenience sampling. Phase 1, a culturally appropriate version of the ESES was developed in the Indonesian language. Phase 2, the psychometric properties were determined through exploratory factor analysis, bootstrap factor analysis, and confirmatory factor analysis. The internal consistency reliability was tested using Cronbach's a, whereas the stability using intraclass correlation coefficient to assess. Results: The students' ages ranged from 17 to 39 years, and 65.0% were women. For translation equivalence, the mean item content validity indexes ranged from 3.5 to 4, and all items were understandable. The 16-item scale exhibited cross-cultural appropriateness and readability, with a three-factor model explaining 62.3% of the variance in exercise self-efficacy. A bootstrap analysis using 100 resamples further confirmed the three-factor model. The indices of the good-fit model that used the three-factor by two-stage least squares method were satisfactory, with c2/df ¼ 3.3, goodness of fit index = .88, and root mean-square error of approximation = .05 (p < .001). The Cronbach's a was .78, .80, and .92 for factors 1, 2, and 3, respectively. The test–retest reliability was demonstrated with an intraclass correlation coefficient of .91, indicating adequate measurement stability. Conclusion: The 16-item ESES-I has acceptable validity and reliability; however, a broader application of the scale requires further testing in different populations to confirm its external validity.

Metal surfaces treated with pulsed electron beams having a power density of some MW/cm^2 show a wavelike surface after solidification. For several applications, the waviness of the surface-modified layers has to be limited and, more importantly, controlled. Therefore, the development of such treatment-induced roughness is investigated systematically. Time- and space-resolved imaging of the target surface and measurement of the intensity modulation of a reflected laser beam are the diagnostic tools applied to evaluate the origin and development of the roughness during melting and solidification. The intensity modulation measurements of the reflected laser beam are performed using a HeNe-laser (632.8 nm) in normal reflection. A streak camera (Hamamatsu C7700) with high dynamic range is used, as well as a framing camera by PCO Imaging. This allows the time evolution to be measured and the target surface to be visualized with high spatial resolution. Metals with significantly different physical (paramagnetic and diamagnetic) and thermodynamic properties, like Ti, Ta, stainless steel, Al, Ag, and Au, are investigated in these experiments. The results indicate that the surface waviness mainly depends on the physical and the thermodynamic properties of the target materials and that the electron beam parameters play only a secondary role.

In this paper, we review the progress that has been achieved at Karlsruhe Institute of Technology (KIT) for several industrial scale projects and in basic investigations based on intense particle beams and pulsed power technologies.
