The purpose of this paper is to analyze theoretically and empirically spillover effects of fishery quota on related markets through their demand curves. Theoretically, the spillover effects of a change in quota can be captured through the directly distorted market alone by computing surpluses associated with the new and old equilibrium. This study estimates empirically demand functions in the context of both the partial equilibrium and general equilibrium. The spillover effect can be computed from the difference between these two estimates. The econometric methodology to estimate the demand curves in the context of general equilibrium is presented and illustrated. The empirical result of fishery markets shows that spillover effects transmitted across other markets are not small and approximately account for 43.3% of the partial equilibrium welfare effects.

This paper presents the effects of partial dampers on the lateral vibration of beams. Both shear and normal stresses in the viscoelastic layer were studied. Analytical results were compared with those obtained by a finite element method. Effects of the size of partial dampers on the system loss factors and resonant frequencies were discussed.

The vortex tube is a simple device for separating a compressed fluid stream into two flows of high and low temperature without any chemical reactions. Recently, vortex tube is widely used to local cooler of industrial equipments and air conditioner for special purpose. The phenomena of energy separation through the vortex tube were investigated to see the effects of cold flow inlet-outlet ratios and partial admission rates on the energy separation experimentally. The experiment was carried out with various cold flow inlet-outlet ratios from 0.28 to 10.56 and partial admission rates from 0.176 to 0.956 by varying input pressure and cold air flow ratio. To find best use in a given cold flow inlet-outlet ratio and partial admission rate, the maximum temperature difference of cold air was presented. The experimental results were indicated that there are an optimum range of cold flow inlet-outlet ratio for each partial admission rate and available partial admission rate.

The pharmacological therapies and whole body vibration as non-pharmacological therapies were known to have adverse side effects. Therefore, partial stimulation was suggested and its effects were evaluated. This study aimed to evaluate the site-specific effects of partial stimulator for treatment of osteoporosis induced by estrogen deficiency. Sixteen virginal Sprague-Dawley rats (12 weeks old) were divided into 2 groups(no stimulation, stimulation groups). All rats were ovariectomised to induce osteoporosis. After 3 weeks of operation, the right tibiae in rats of stimulation group (frequency: 10Hz, cycle: 1500, strain on bone surface: $2000{\mu}{\varepsilon}$) were stimulated perpendicularly at right tibia by using partial stimulator for 6 weeks (3days/week). The right tibiae in rats were scanned, before stimulation (0 week) and at 6 weeks after stimulation by using in-vivo micro computed tomography. For investigation of changes in morphological characteristics, structural parameters were measured and calculated. At 6 weeks the morphological characteristics (relative value) in stimulation group were significantly enhanced than those in no stimulation group (p<0.05). In this study, we find that after 6 weeks of partial stimulation, the morphological characteristics of tibia trabecular bone were enhanced. Thus, we concluded that partial stimulation could be used to treat osteoporosis.

In this study, a four-node quadrilateral partial mixed plate element with low degrees of freedom (dofs) is developed for static and free vibration analysis of functionally graded material (FGM) plates rested on Winkler-Pasternak elastic foundations. The formulation of the presented finite element model is based on a parametrized mixed variational principle which is developed recently by the first author. The presented finite element model considers the effects of shear deformations and normal flexibility of the FGM plates without using any shear correction factor. It also fulfills the boundary conditions of the transverse shear and normal stresses on the top and bottom surfaces of the plate. Beside these capabilities, the number of unknown field variables of the plate is only six. The presented partial mixed finite element model has been validated through comparison with the results of the three-dimensional (3D) theory of elasticity and the results obtained from the classical and high-order plate theories available in the open literature.

In the partial lubrication regime, the roughness effects are most important due to the presence of interacting asperities. An average Reynolds equation using flow factors is very useful to determine effects of surface roughness on partial lubrication. In this paper, the pressure flow factors for Gaussian and non-Gaussian surfaces are evaluated in terms of kurtosis. The effect of kurtosis on pressure flow factor is investigated using random rough surface generated numerically. The pressure flow factor increases with increasing kurtosis in partial lubrication regime(h/$\sigma$<3). As h/$\sigma$increases, the pressure flow factor approach to 1 asymptotically regardless of kurtosis.

In this study, the effects of water vapor in inlet air, spark advance and fuel type in the spark ignition engine were investigated through the experiments of combustion and flame arriving pattern analysis using ionization probe. The results of flame propagation experiment using ionization probe show that the flame which ignited from spark plug located at the center of the combustion chamber propagated faster in exhaust side than in intake side due to the mixture flow motion inducted into combustion chamber from intake tumble port at all conditions. And as the partial vapor pressure increased, the flame propagation became slower in all direction. Especially effects were greater for intake side than the exhaust side.

Generally, we take a bath to obtain a clean body as well as a good health. Human body generates various physical and emotional changes by stimulations of therapeutic effect of heat and hydraulic pressures. Accordingly, we can obtain not only relaxations but also effects of hydrotherapy. The survey of bathing/showering behaviors and therapeutic effect of heat reactions present elementary data for development of a bathing/showering system. However, there are few existing data for bathing/showering behaviors and effects. Consequently, surveys were performed to know patterns of bathing and showering, and relations between physiological changes and water temperature were examined by partial bathing on human body in this study.

We investigated the effects of residual gas partial pressure on the property of a CeO$_2$ buffer layer on a textured Ni tape, where the buffer layer was deposited by e-beam evaporation. The oxygen partial pressure were varied from 10$^{-7}$ to 10$^{-4}$ Torr. we also changed the surface condition for the surface oxygenation. We'll describe the detail of the resultant textures of the buffer layers and effects of YBCO growth on them

The effects of partial pressures of various gases on the qualities of coated conductors are studied, where the long samples were fabricated in a vacuum of a large physical vapour deposition system. The various gases such as $0_25,$H_2$,H_20$,$C_n H_m$, and CO come out from the large heating system and gives somewhat complicated effects on the interfacial chemistry at CeO/Ni which Is Important for the epitaxial growth of the film. The results of XRD measurements on the films fabricated in the controlled partial pressures of thoes gases will be presented.
