Perception of Foreign Tourists to Karawo Embroidery Handicrafts in Gorontalo Tourist Destinations

The purpose of this study was focused on knowing the perceptions of tourists, both foreign tourists, about the craft of Karawo embroidery in Gorontalo Tourism Destinations. This research method using a quantitative approach itself is carried out using a questionnaire given to the public and tourists who visit the Karawo embroidery craft center. The sampling technique in this study used a non-probability or non-random sample selection technique. The results showed that the quantitative approach itself was carried out using a questionnaire given to the public and tourists who visited the Karawo embroidery craft center. The sampling technique in this study used a non-probability or non-random sample selection technique. The results of this study indicate that the Karawo embroidery craft has the potential to be developed as a tourist attraction in Gorontalo Province. Analysis of the attractiveness and perceptions of tourists who visit the Karawo embroidery craft center as well as the local community provide direction on the development of tourist attractions that are related to cultural aspects. The perception of foreign tourists in general gives a positive value to Karawo embroidery and argues that Karawo embroidery is unique from the manufacturing process and has its own characteristics with very beautiful motif designs.

Stability Analysis of Celestial Objects and Cosmos

In this thesis, we study various evolutionary aspects of relativistic collapsing systems, thin-shell wormholes as well as cosmos by incorporating the e®ects of di®erent physical parameters. We consider both spherical and cylindrical stellar objects ¯lled with electromagnetic °uids and discuss their dynamical instability under radial oscillations. The dynamical instability of homogeneous sphere as well as relativistic polytropes is discussed by taking di®erent values of charge in Newtonian and post Newtonian regimes. Moreover, we evaluate the ranges of radii as well as adiabatic index for both charged and uncharged dissipative homogeneous cylinder. It is noted that dynamical instability occurs in the presence of charge if the gaseous mass contracts to the limiting radius. We discuss stability of thin-shell wormholes coupled with nonlinear electrodynam- ics in the vicinity of di®erent cosmological models for exotic matter. A general equa- tion of state is considered in the form of linear perturbation which explores stability of the respective wormhole solutions. We assume linear, logarithmic and Chaplygin gas models to study exotic matter at thin-shell and evaluate maximum viable regions for stability with di®erent values of the involved parameters. We also study stability of thin-shell wormholes in Einstein Ho®mann-Born-Infeld electrodynamics following the same dynamical approach. It is found that the Ho®mann-Born-Infeld parameter and electric charge enhance the stability regions. Finally, we discuss dynamical stability of isotropic and homogenous universe model via phase space analysis by taking a noninteracting mixture of electromagnetic and viscous radiating °uids whose viscous pressure satis¯es a nonlinear version of the Israel-Stewart transport equation. We evaluate corresponding critical points for var- ious choices of physical parameters. It is found that bulk viscosity as well as elec- tromagnetic ¯eld enhances the stability of accelerated expansion of the isotropic and homogeneous cosmos. We also study phase space analysis of locally rotationally sym- metric Bianchi type I universe model by taking di®erent linear combinations for the interactions between scalar ¯eld models and dark matter. This indicates a matter dominated epoch ultimately followed by a late accelerated expansion phase. We con- clude that all the critical points lead to accelerated expansion of the universe for tachyon coupled ¯eld.
