"ABSTRAKNationalism provides foundation for the love of one's nation. This feeling is based on the shared history and mutual purpose for the future, which stand on solidarity and feeling of unity in a certain group. However, nationalism can often be used as justification for national fanaticism that sacrifice the interests of other groups or other nations. A new interpretation of nationalism in the cosmopolitan era is needed, where interdependence between nations and groups become a concrete and factual reality, and at the same time, the consciousness that human as an integral part of universal order is increasing. This article is an effort to place nationalism in the cosmopolitan framework, which puts highest importance on struggle to create tolerance, solidarity and social equality."

"As mentioned before in the submitted proposal, the aim of this investigation is to study the wide angle reflection characteristic which has both advantage and disadvantage. The advantage we could obtain from such reflection angle is the stronger reflections (i.e S/N ratio) compared to the narrower angle reflections. This strong reflection makes the horizon identification becomes easier and its amplitudes might be used to study the rock properties using inversion technique. Its disadvantage comes from the fact that wide angle reflection involves what co-called chase distortion that affects the travel-time picking and also the amplitude measurement.Some workers have studied the phase distortion effect and proposed some methods to overcome the problem. Choy and Richards [2] who studied seismograms produced by a caustic region found the similarities between event in the original seismograms and the Hilbert transformed seismograms. They observed that, for example, an sS-wave is a Hilbert transform pair of an SS-wave, which suggested a 90° phase distortion. To tackle the problem of obscure travel-time, they applied the matched filter to the distorted signal after Hilbert transforming the reference signal. This method, however, is limited to 913° phase distortion only.The matched filter is a simple and straightforward method to estimate the amplitude ratio and differential travel-time of two different signals. However, it works well only when both signals have similar waveforms. When the phase distortion occurs, i.e. the original waveform is distorted, the matched filter fails to obtain an optimum amplitude and travel-time estimations. Pointer and Neuberg [8] introduced an iterative matched filter for analysing the effect of a phase distortion. First, the reference signal is phase distorted and used to find the amplitude ratio and travel-time by matched filter. The procedure is repeated ti changing the phase with a particular increment until they obtain the best cross-correlation value automatically revealing the amplitude ratio, the differential travel-time, and the phase distortion. However, the method is sensitive to the choice of the phase increment and in some cases it."

This Engineering Practice Report discusses the process of build the Welcoming Dinner and Cultural Performing Art G20 indonesia 2022 stage. This research was obtained by direct observation in the field as a designer and as a field supervisor, which was carried out for 13 months from developing the design to dismantling the set, as well as carrying out several surveys and simulations to find the best results. The results of this study suggest that designers in design development must use supporting theory, know and develop technical knowledge and discuss finding solutions with other parties involved."
