Positive politeness strategy used by Jae Min Jung and Mari Baek in orange marmalade webtoon
Get PDFThis research attempted to analyze the usage of positive politeness strategy used by Jae Min Jung and Mari Baek in Orange Marmalade Webtoon’s English version. The aimed of this research was to found out what kinds of positive politeness strategies that used by Jae Min Jung and Mari Baek and the factors that influence JaeMin Jung and Mari Baek used polite strategy. This research, the researcher applied qualitative approach. The source of data was taken from webtoon and the data were taken from the utterances which consist of words, phrases, and sentence that expressed by Jae Min Jung and Mari Baek in Orange Marmalade webtoon. The researcher used theory about positive politeness strategy from Brown and Levinson (1968) and some other supporting theories to conduct this research. By this research, the researcher found that the main characters Jae Min Jung and Mari Baek applied ten positive politeness strategies. Those strategies were Avoid Disagreement, Notice, attend to hearer (his interest, wants, need, goods), Intensify to the hearer activity, Seek agreement, Include both speaker and hearer activity, Exaggerate (interest, approval, sympathy, with the hearer), Give gift to the hearer (goods, sympathy, understanding, cooperation), Presuppose/ rise/ assert common, Offer and promise, and Assume and assert reciprocity. And the researcher also found two factors that influenced the main characters used positive politeness strategy. Those are payoff and social distance. The main characters used those factors as a mean to maintain the social distance between the speaker and the hearer. By reading this study the researcher hopes, this study will be useful and be inspire work for the readers, especially, for students of English Department to understanding positive politeness strategy
Flow near a slowly rotating disk in a finite cylinder
No full textNumerical soilutons for the steady flow of a viscous fluid driven by a slowly rotating disk in a cylinder of finite aspect ratio are presented. Based on the comprehensive flow data acquired, the torque exerted on the disk is computed. The radial and axial structures of both the azimuthal and meridional flow details are exhibited. The effect of small, but non-zero, Reynolds number is discussed. The torque increases rapidly as the disk-cylinder radius ratio approaches unity because of the concentrated flow gradients near the tip of the disk. As the cylinder aspect ratio increases, the torque decreases. The flow can be approximated by the infinite cylinder model if the aspect ratio is greater than about 2.0. The theoretical torque estimate by using the infinite cylinder configuration is shown to be in reasonable agreement with the numerical results for large aspect ratios
Internal wave dispersion in deep oceans calculated by means of two-variable expansion techniques
No full textAn analytical study is made of linearized internal wave dispersion relation in a density-stratified deep ocean with a N(z) profile which contains turning points. Principal emphasis is placed on obtaining the Ω-k relationship for all frequencies. Taking advantage of the largeness of the nondimensional wavenumber (kS≫1), the mathematical tool to attack the governing Sturm-Liouville equation is a combination of the two-variable expansion (valid far away from the turning point) and the limit-process expansion (valid in the neighborhood of the turning point). The matching conditions for these two expansion schemes provide the desired Ω-k relationship. A numerical example of this method demonstrates satisfactory agreement with the results obtained by the strict analytical solution and the multi-layered matrix numerical model. © 1976 Oceanographical Society of Japan
Flow of a Stratified Fluid Bounded by Walls of Finite Thermal Conductance
No full textA study is made of the behavior of a thermally stratified fluid in a container when the non-horizontal boundaries have finite thermal conductance. The theory of Rahm and Walin is briefly recounted. Numerical solutions to the Navier-Stokes equations for a Boussinesq fluid in a cylinder, adopting a Newtonian heat flux condition at the vertical sidewall, are presented. Results on the details of flow and temperature fields are given over ranges of the Rayleigh number Ra, the container aspect ratio H, and the sidewall conductance S. As S increases, the isotherms in the meridional plane are horizontal at small radii but they diverge at large radii. This creates temperature nonuniformities in the horizontal direction, and convective motions result. The salient features of the interior temperature profiles are captured by the theoretical model. The velocity field is characterized by two oppositely-directed circulations. As Ra or S varies, the qualitative circulation patterns remain substantially unchanged, but the magnitudes of the convective flows differ by large amounts. The effects of the externally-imposed parameters on the flow and temperature structures are examined
Some stability properties of large-scale baroclinic flows with nonlinear zonal current profile
No full textThe stability properties of a baroclinic zonal current with nonlinear velocity profile are investigated. The integral method is applied to the governing eigenvalue equation having the vertical velocity as the dependent variable. Expressed in terms of the Rossby number and the Richardson number, stability criteria, unstable regions in the complex c plane, and the upper bound of the unstable wave growth rate are found. Some differences in the results are noted between the present model and the quasi-geostrophic streamfunction model, particularly in connection with the effect of the velocity profile curvature term Uzz. It is conjectured in the present model that, depending on extreme behaviors of Uzz, the propagation speed of unstable waves can be greater than Umax or smaller than Umin. © 1977 Oceanographical Society of Japan
