The success of Newton's Gravitational Theory has influenced the theory of capillarity, beginning in the early nineteenth century, by providing a major model of molecular attraction. He used the equation of the attraction of spheroids, which is expressed by second order partial differential equations, to utilize this analogy as the same kind of a particle's force, between gravitational, refractive force of light, and capillarity. The solution of the differential equation corresponds to the geometrical figure of the vessel and the contact angle which is made by the fluid. Unknown abstract functions $\varphi(f)$ represent interaction forces between molecules, giving their potential functions. By conducting several kinds of experimental conditions, it was found that the height of the ascending fluid in the tube is inversely proportional to the rayon of the tube or the distance of the plate. This model is an essential element in the theory of capillarity. Laplace has brought Newtonian mechanics to completion, which relates to the standard model of gravitational theory. Laplace-Young's equation of capillarity is applicable to minimal surfaces in mathematics, to surface tensional phenomena in physics, and to soap bubble experiments.

This article is designed to establish fundamental design criterion for theme park cast costumes in accordance with play type and space. There is an understanding that theme parks act as a play space that is designed to meet diverse playing desires. To analyze cast costumes, the theme park - 'Everland' in South Korea as an example, area was divided into attraction space and non-attraction space. Attraction space is mainly for full-scale play content areas and the non-attraction space is to enforce the attraction space experience. Roger Caillois's play theory states that there are 4 play types; Illinx, Mimicry, $Ag{\hat{o}}n$, and Alea. All 4 play types were shown through attraction and Mimicry at non-attraction. Each cast costume was analyzed in terms of apparel design elements - silhouette, textile, color, detail, and props - related to play type facility and cast role. Criteria for theme park cast costume designs were suggested based on the results. Illinx cast members who fulfill a safety-checking role wear high chroma warm color costumes with the accent on details in bodice cutting lines, collar edges, pockets, buttons and decorative ornaments. A complementary contrast is also used. The guidance cast in Illinx may wear a suit in bright/vivid color. Mimicry guidance cast costumes show meticulous perfection in imitation with the figure in its space. From head to toe, color, textile, and silhouette - every detail and even props should match the character. $Ag{\hat{o}}n$ cast costumes are strictly limited in detail and decorative ornament usage as well as in color, since they are in charge of the management and operation of a competition. Alea cast's role is a self-demonstrator. Alea cast members should be a real tarot card reader. However, a manual should control their costumes. A total of 10 cast roles at a non-attraction space should be designed to show job patterns clearly in accordance with the whole theme at the park.

The purpose of this study is to suggest the analytical framework for a spatial structure of a tourism destination master plan by the two types of the tourism development models: Tourist attraction System Model and Tourism Destination Region Design Model. The resort development plan is introduced as a planning tool for regenerating the eastern Pusan regions, but the economic and environmental impacts and the sociocultural dilemma accompanied by the development should be fully considered before launching the business. The development plan announced currently is traced and examined in comparison with the upper-leveled and related plans. The Tourist Attraction System Model based on the systems theory is applied to the designated regions. The Tourism Destination Region Design Model then is applied for analyzing the components of each region on the master plan. The results of the findings suggest that the tourism destination plan is basically different from a general master plan on the physical comprehensive plan, the destination is recognized as a subsystem of the whole tourism system, and thus tourism destination plan is considered as a spatial arrangement of tourism facilities and the inter- and intra-circulation.

Director Choi Donghoon is the most famous director in Korea as a box office successor, especially (2102) has gained No. 1 box office attraction in Korean film history. However some critics have criticised the works of Dr. Choi because of their plebeianness. This paper focused on the reason of interaction with audiences through the theory of carnival of Mikhail M. Bakhtin. Because the theory of carnival is not only the adapted method to account for the power of popular culture to M. Baktin but also the useful method to understand the keys of interaction of Dr. Choi's films. It's not difficult to find the esthetic elements of carnival theory example for 'dethronement & coronation', 'overturn & ridicule', 'image of feast', 'language of square' in the films of Choi which are The Big Swindle(2004), Tazza: The High Rollers(2006), Woochi(2009), The Thieves(2012). Therefore this paper has endeavored that the box office attraction and success of communication with audiences is due to the realistic attitude and social reflection of Choi's films.

Stability analysis of nonlinear systems is mostly based on the Lyapunov stability theory. The well-known Lyapunov function method provides precise and rigorous theoretical backgrounds. However, the conventional approach to direct stability analysis has been performed without taking account of damping effects, which is pointed as a minor but crucial drawback. For accurate has been performed without taking account of damping effects, which is pointed as a minor but crucial drawback. For accurate stability analysis of nonlinear systems, it is required to take the damping effects into account. This paper presents a new method to derive a group of Lyapunov functions to reflect the damping effects by considering the integral relationships of the system governing equations. A systematical approach is developed to convert a part of damping loss into some appropriate system energy terms. Examples show that the proposed method remarkably improves the estimation of the region of attraction compared considering damping effects. The proposed method can be utilized as a useful tol to determine the region of attraction.

The classical-fluids density functional theory has been developed for studying the structural and the electrical properties of electrolyte solutions containing uniformly charged hard-spherical ions. The modified fundamental-measure theory has been used to evaluate the hard-sphere contribution. The mean-field approximation has been employed to calculate the cross correlation between the hard sphere contribution and the Coulomb interaction. The Poisson equation for ions carrying charges that are spatially separated has been solved. The present theory shows reasonably good agreement with the corresponding Monte Carlo simulation results. The calculated results show that the attraction between like-charged planar surfaces is the result of the intra-ionic correlation and depends strongly on the ion size, valence, mole fraction, and charge distribution of electrolytes.

To put it simply, thing theory is a study of meaningful capacities of materiality. Although T. S. Eliot regarded pathetic fallacy as the bad example of objective correlatives in his modernism poetry theory, it is clear that many objects in literary works reflect diverse human desires. Among many, Victorian sensation novels are the most distinct genre where the various paraphernalia in them indicate the distorted and exaggerated greed of the industrial revolution era. Whereas the male protagonists are usually related with the norms objects of authority such as portrait and locket, the female characters' connection with cosmetics and white dress shows their oppressed and fragile position in the patriarchal and hierarchical society. In the (post)modern society, the ambiguity of things has grown rapidly due to the increasing discrepancy between objects and things. In special, the new journalism and the psychological realism novels often reveal the post-truth phenomenon because consumerized audience depend more upon the attraction and affect than the mere evidence and facts. For the individual, according to object relations theory, these alternative facts are rather internalized into their mind as the internal object when they are motivated by the non/contact with primary caregivers in their childhood. The dominant material imagery in (post)modern fiction becomes the site of resistance because of their reconstructed and extended meaning. The object relations theory and thing theory can be effectively used to uncover the complicated meanings of desired objects by using the human-object's meaningful relations and early mental images that are secretly alive still in the present.
