In my paper, an evaluation method on naturalness and urbanness characterizations of animation image is proposed. In contrast to the prior works, we intend to give the exact degree of naturalness and urbanness by combining the low-level visual feature-based schemes with the biological visual schemes. In our method, four descriptors are extracted and pseudoinverse is adopted. By this method, we can experiment on the exact degree of naturalness and urbanness with satisfactory results.

In retrieving process in angle multiplexing Holographic Data Storage(HDS), It is important to search the exact recording angles. In this paper, we propose the retrieving angle searching method using pre-scan. Pre-scan method is means that rotating the galvano mirror before the retrieving process. Therefore, retrieving signals are maximized when between the galvano mirror and recoded angle are exactly matched. Through the measured signals, we will find the exact angle and compensate tangential tilt angle. The experimental results shows propose method is enough to apply the HDS.

Development of the economy and the growing income of people interested in the leisure and health has been focused. Past the town common wells and groundwater around the water, but health is a priority these days to solve the drinking water directly from tap water, but most people work from home, through the water purifier has been resolved. Depending on seasonal changes and personal taste of coffee, if you can enjoy a snack and water purifier is a restaurant, lounge, public areas and focusing on the rapid spread of the fire, water purifier as compared to the total number of fires increased by 0.03% per year trend on, but the washrooms fire and fire-related research data and case studies with analysis of the exact cause lack of proper preventive measures are insufficient reality. In this study, focusing on electrical energy using a water cooler to understand the structure and principles of fire, the fire revealed the mechanism is vulnerable to the consideration of factors, the exact cause of the fire investigation and the Assistant, manufacturing defects, and to contribute to fire prevention review should.

Ramik[7] introduced a fuzzy goal programming (FGP)problem that generalizes a standard goal programming (GP) problem with fuzzy alternatives, fuzzy objective functions and fuzzy deviation functions for measuring the deviation between attained and desired goals being fuzzy. However, it is known that this FGP tends to produce an approximate solution since it uses an approximate fuzzy multiplication operation to solve the resultant fuzzy model. In this paper, we show that this FGP sometimes leads to the wrong decision. We also propose a procedure that gets the exact solution to overcome these problems. The method is based on $T_M$ (min norm)-based fuzzy operations using $\alpha-cut$ representations. We consider the same example as used in Ramik and investigate how our procedures are compared to Ramik's.

The differential quadrature method (DQM) is applied to computation of eigenvalues of the equations of motion governing the free in-plane and out-of-plane vibrations for circular curved beams. Fundamental frequencies are calculated for the members with various end conditions and opening angles. The results are compared with existing exact solutions and numerical solutions by other methods (Rayleigh-Ritz, Galerkin or FEM) for cases in which they are available. The differential quadrature method gives good accuracy even when only a limited number of grid points is used.

This paper presents the development of depth extraction algorithm for the stereoscopic endoscope data using a stereo matching method. generally, the purpose of existing stereo algorithms is to reconstruct stereo object surface and depth map. but the main purpose of our processing is to give exact depth feeling to doctor showing depth information in some points. for this purpose, this paper presents two stereo matching algorithms which are to measure exact depth. one is using variable window, and the other is reference points-based algorithm for a fast processing.

The interactions between the excavation tool and the excavation environment are dynamic, unstructured and complex. In addition. operating modes of an excavator depend on working conditions, which makes it difficult to derive the exact mathematical model of excavator. Even after the exact mathematical model is established, it is difficult to design of a controller because the system equations are highly nonlinear and the state variable are coupled. The objective of this study is to design a fuzzy logic controller (FLC) which controls the position of excavator's attachment. This approach enables the transfer of human heuristics and expert knowledge to the controller. Expeiments are carried out to check the performance of the FLC.

This paper is for the transient analysis of instant short-circuit test equipment according to the test of tripping limits and characteristics under IEC 60947-2. The in-rush current is harmful to almost equipments and the exact testing is not made because of it. LGIS has a instant short-circuit test equipment, but it is not suitable for carrying out instant short-circuit test on ELB(Earth Leakage Circuit breaker) by reason of that. Now, I am going to show a solution for that problem. After applying this method, manufacturer is going to acquire the exact testing result according to the IEC standard. Moreover, Testing laboratory will be trusted by clients.

This study investigates the stress distribution in a transversely isotropic medium containing a spheroidal cavity where the medium is under uniaxial tension in z-direction in one case and pure shear in the plane of isotropy in another case. The technical approach used in this study combines exact analytical and numerical methods. The exact analytical method is based upon three potential functions taken in terms of the Legendre associated functions of the first and second kind. The numerical method is based upon the finite difference approach. Numerical results concerning the two loading conditions with five anisotropic materials are presented.

It is concentrated their efforts on expanding establishment mind like creating regular subject about establishment business of students and establishment business supporting center in University. Students creation enterprise club for establishment business with this hot wind of change and it seems to be success with hot wind of venture creation and gather many students for it. But practical result of research says that there are many problems like absence of education program, insufficient of professional leader, missing exact purpose so members decreased and activity itself piled up. Also creation business supporting system for student didn't conveyed to students evenly and effectively as much as original purpose and feeling effect is short of expectation. Therefore it will be required to reorganize supporting system and operate existed club to raise their ability of basic quality and gift that needs to do company activity and create basic mind about principal of free enterprise through activity of establishment enterprise by students. And we have to interest in their activity for creation enterprise with exact consciousness of purpose and prepare systematic, material, human supporting system that needs to establish enterprise with our knowledge and ability.
