The purpose of this study is to investigate the transformation of affordance in iOS GUI design and the relationship of affordances. We figured out variety kinds of Affordance concepts and choosed six Affordances(Visceral, Behavioral, Reflective, Explicit, Metaphorical, Pattern Affordance) Based on the previous studies. The result of investigating the transformation of iOS GUI design which based on the viewpoint of these 6 Affordance we have chosen is as follows. Firstly, the Visceral Affordance of iOS GUI design has already sufficiently become to the Reflective Affordance. So we can ignore or ellipsis the Visceral Affordance and the addition of specific Explicit Affordance can be possible. Secondly, due to the use experience of iOS, Behavioral Affordance and Pattern Affordance have already become to a kind of Reflective Affordance. Through this evolution, new kind of Pattern Affordance is formed. At the mean time, it also applied the basic field of Metaphorical Affordance. Thirdly, investigating the Flat Design of iOS based on the viewpoint of Affordance, we have figured out that Visceral Affordance has been reduced. So that the constrains of visual performance has also been reduced. This is the reason that there are more space remained in screen layout design, the color has become more natural and more Explicit Affordance has been provided, ect. Futhermore, in this thesis we have also figured out that there are some interactions and relationships between each Affordance. With the development of iOS, some Affordances have transformed to other Affordances. With the accumulation of use experience, Visceral Affordance has transformed to Reflective Affordance based on the field of Metaphorical Affordance. With the disappearance or reduction of Visceral Affordance, iOS provide Explicit Affordance instead. As a result of this kind of process, a new Pattern Affordance has been formed.

Staurolite-biotite-andalusite-garnet (SBAG) assemblage and its sub-assemblages (SBA and SBG) commonly occur in the Dueumri Formation near the Chunyang granite, belonging to andalusite and sillimanite zones. The occurrence of the SBAG mineral assemblage is unusual because it is univariant in the $K_2O-FeO-MgO-Al_2O_3-SiO_2-H_2O$ (KFMASH) model system. We used projection and singular value decomposition (SVD) methods to investigate the equilibrium relationship between SBAG and its sub-assemblage. The SVD modelling of single specimen containing the SBAG assemblage suggests no reaction relationship with respect to mass-balance. Thus, the SBAG assemblages are stabilized by non-KFMASH component. On the other hand, the AFM-Mn projection suggests a reaction relationship between SBAG and its sub-assemblage because they intersect each other in this composition space. The SVD modelling, however, suggests no reaction relationship between these assemblages. Thus, the SBAG assemblages are likely to be stabilized by the variation in bulk-rock composition and/or 1.1~2,. The stable occurrence of staurolite in the sillimanite zone is compatible with pressure estimates from the garnet-plagioclase-biotite-muscovite geobarometer.

The flow characteristics around KRISO 3600TEU container ship model have been experimentally investigated in a circulating water channel. The instantaneous velocity vectors were measured using 2-frame PIV measurement system. The mean velocity fields and turbulent statistics including turbulent kinetic energy and vorticity were obtained by ensemble-averaging 400 instantaneous velocity fields. The free stream velocity was fixed at 0.6m/s and the corresponding Reynolds number was $9{\times}10^5$. The test sections were divided into two regions, three transverse sections of the wake region(Station -0.5767, -1, -3) and five longitudinal sections of the wake((Z/(B/2)=0, 0.1, 0.2, 0.4, 0.6). In the wake region, large-scale longitudinal vortices of nearly same strength are symmetric with respect to the wake centerline and a relatively weak secondary vortex is formed near the waterline. With going downstream, the strength of longitudinal vortex is decreased and the wake region expands.

Recently. the interest in Physical distribution has increased in economic geography This paper aims to review and prospect the internatonal physical distribution studies of international trade and international freight flows. And it has examined the changes in methodology of international physical distribution. Author has defined international physical distribution as the physical distribution of international trade and international freight flow The results are as follows : (1) As the methodology of international physical distribution studies developes, the physical distribution should be recognized not only as transportation phenomenon but also as total logistics which is understood as the combination of production and consumption including information flow. (2) The studies about model of international physical distribution flow ill need to study regional relations including urban, in the future. And economic geography and location theory adding culture and behaviour elements will be restructured, because not only state but also multinational corporation appear as trade subject in global economy. (3) The studies for the relation of habor and its hinterland in Physical distribution need to analyze the factors causing habor use with decision-making behaviour of corporation. (4) After oil crisis. as air freight is important, the studies for hinterland and foreland of freight centering international airport are needed because of necessity of light and small freight. flexible Production system, free trade, and high speed freight transportation of freshing food and flowers and so forth.

New directions on rural policy have been discussed due to the domestic and international environmental changes such as the price degradation of agricultural products, maintenance of rural landscape, and so on. Development of amenity in rural areas has been come out as the one of new policy directions. Amenity defines as, in a very broad way, the public benefits accruing from the condition of a place, such as aesthetic beauty, clean air and water, or good street lighting. Amenity in rural area is referred as a resource with a potential possibility for development. Among them rural landscape is regarded as the one of major resources. In Jeju, particularly, stone wall retains the most esthetic landscape in rural regions. In addition, the Ministry of Culture and Tourism appointed stone wall as the one of important components in rural landscape and one of the 100 national historic symbols. Stone wall in Jeju has its intrinsic and real value and is widespread in rural regions. However, in spite of it's popularity, the landscape of stone wall has been degraded without any concerns and has been partly destroyed. Landscape of stonewall should be maintained and the depth of concerns and systematic management measures for protection should be discussed. In this sense, the purpose of this paper, first of all, is to examine the status of stone wall and to evaluate the landscape of stone wall in Jeju. GIS is used as an analysis tool. Several areas such as Hankyung, Namyeup, and so on in Jeju are selected as the case areas for this study.

Submarine gas fields have focused because of the increasing fuel cost, the environmental regulations, and the safety & NIMBY problems. LNG-FPSO which is available for acid gas removal, recovery of the condensate & LPG and Liquefaction in topside process is one of high technology offshore structures. On the other hands, it is necessary to verify the pre-treatment efficiency by the ship motion and to apply to the design for LNG-FPSO. This study is to develop the pre-treatment technology for LNG-FPSO as taking account to the process efficiency by ship motion effects and the area optimization. Based on the simulation results, it founds that hybrid process shows the low circulate rate, the low heat duty and the small size of column dimensions compared to typical amine process. It will be verified the process efficiency in the various conditions by sea states as performing the 6-DOF motion test and CFD simulation.

Robot manipulator is a highly nonlinear-time varying system. Therefore, a lot of control theory has been applied to the system. Robot manipulator has two types of control; one is path planning, another is path tracking. In this paper, we select the path tracking, and for this purpose, propose the intelligent control¬ler which is combined with fuzzy logic and neural network. The fuzzy logic provides an inference morphorlogy that enables approximate human reasoning to apply to knowledge-based systems, and also provides a mathematical strength to capture the uncertainties associated with human cognitive processes like thinking and reasoning. Based on this fuzzy logic, the fuzzy logic controller(FLC) provides a means of converhng a linguistic control strategy based on expert knowledge into automahc control strategy. But the construction of rule-base for a nonlinear hme-varying system such as robot, becomes much more com¬plicated because of model uncertainty and parameter variations. To cope with these problems, a auto-tuning method of the fuzzy rule-base is required. In this paper, the GA-based Fuzzy-Neural control system combining Fuzzy-Neural control theory with the genetic algorithm(GA), that is known to be very effective in the optimization problem, will be proposed. The effectiveness of the proposed control system will be demonstrated by computer simulations using a two degree of freedom robot manipulator.

In this paper, a small round-ended slot loaded by double ridges on the broad wall of a rectangular waveguide is presented as an element for a waveguide slot-array antenna(WSAA). By properly adjusting the ridge dimension, a resonance of the slot at a desired frequency can be achieved. The resonant length of the proposed slot is about $0.26{\lambda}_0$(free space wave length) at the resonance frequency. The proposed resonant slot has some advantageous properties, such as small size, small resonant conductance, and short and stable resonant slot length. In addition, the characteristics of the slots are slightly affected by the adjacent elements when the slots are arrayed for a waveguide slot antenna. A $4{\times}1$ WSAA with -20 dB side-lobe level(SLL) is designed, fabricated, and tested experimentally. The measured results are well agreed with the simulated ones and have an SLL of -15.9 dB and a half-power beam width of $110.2^{\circ}$ in the E-plane and $21.2^{\circ}$ in the H-plane, respectively, at 9.41 GHz.

Dynamics of the river plume is a very complicated non-linear problem with the free boundary changing in time and space. Mixing with the ambient water through the boundary makes the problem more complicated. In this paper we reduced 3-dimensional problem into 1-dimensional one by using the integral analysis method. Basic equations have been integrated over the lateral and vertical variations. For these integrations we adopted the well-established assumption that the flow-axis component of plume velocity and the density difference of the plume with the ambient water have Gaussian distributions in directions which are perpendicular to the flow-axis of the plume. We also used the result of our previous study on the lateral spreading velocity of the plume derived under the same assumption. And entrainment was included as a mixing process. The resultant 1-dimensional equations were solved by Runge-Kutta numerical method. Consequently, comparatively easy method of numerical analysis is presented for the 3-dimensional river plume. The method can also be used for the analysis of the thermal plume of cooling water of power plants.

Mr. Miyazaki's heroines tend to be plucky young women who combine guileless decency with tough-mindedness. However, in his the latest film the female character often change herself into wise older women who sometimes serve as foils, sometimes as mother figures. His heroine, Sophie, starts out as a shy girl, but then a curse transforms her into 90-year-old. Her partner is Howl who supports and is supported by Sophie their mutual drawbacks. At first horrified by the change, she comes to embrace it as a liberation from anxiety, fear and self-consciousness, and discovers in herself a new zest for adventure. The castle is surely one of the most extraordinary contraptions to appear on screen recently, more ingenious in its way than the intergalactic armada. It ranges freely from place to place and is also, somehow, in several places at once, its magical front door opening onto different landscapes with the flip of a knob. It is not exactly haunted, but it is nonetheless infused with whimsical and sometimes somber spirits. Sophie, in both her incarnations, joins an impressive sisterhood of Miyazaki heroines, whose version of girl power presents a potent alternative to the mini-machismo that dominates American juvenile entertainment.
