This study was clinically performed with the 73 outpatients of urticaria who had visited the Dept. of Dermartology, Oriental Medical Hospital, Dong-eui University from January 1st 2000 to June 30th 2003. They have all taken the oriental herb medicine as Sungmagalguntanggamibang(SGT, 升麻葛根湯加味方) more than 1 time. Urticaria is a common disease and a well known reaction pattern of the skin charaterized by erythema, wheals and edema, that is the results of various causes. Urticaria is classified into acute or chronic type. The etilogy of acute uricaria has been determined in many cases, but the cause of chronic urticaria has been determined in 10$\%$ to 20$\%$ of cases. Character of chronic type urticaria is recurrent pruritus and erythematous skin disease by stimulating factor. Through checking up the present patient state, we verified the effect of SGT in various ways. The results were summarized as follows; 1. An increase of taking a medicine(SGT) and attending a hospital in number let down repeated urticaria occurence. 2. SGT is more effective when the symptoms with the severe pruritic wheals are spread on the whole body in daily occurrence. 3. In urticaria treatment method, gradually reducing a western medicine and going side by side SGT, that is good at symptoms improvement. 4. Etiology of urticaria is classified into intestine-stomach accumulated heat by indigestion(食滯腸胃積熱), wind-moisture(風濕), wind-heat(風熱) etc. The SGT is available in the order of frequency of use.

Enhancing Information Utilization Capability of the elderly is discussed in the level of nation due to the advent of information society and aging. Information divide of the elderly is wider compared with other age groups. It is necessary for the elderly to enhance information ability. Government was implementing the policy for narrowing information divide continually. Dual information divide is brought about by the character of the elderly such as status, economic factor, the level of education. Therefore not only continuous nation's policy but road map is needed for enhancing information utilization capability to computer and internet. Information divide of the elderly would be narrowed out of education, economy, earning, age through those ways.

The dynamic character of a system of the governing differential equations for the one- dimensional two-fluid model, where the momentum flux parameters are employed to consider the velocity and void fraction distribution in a flow channel, is investigated. In response to a perturbation in the form of a＇traveling wave, a linear stability analysis is peformed for the governing differential equations. The expression for the growth factor as a function of wave number and various flow parameters is analytically derived. It provides the necessary and sufficient conditions for the stability of the one-dimensional two-fluid model in terms of momentum flux parameters. It is demonstrated that the one-dimensional two-fluid model employing the physical momentum flux parameters for the whole range of dispersed flow regime, which are determined from the simplified velocity and void fraction profiles constructed from the available experimental data and $C_{o}$ correlation, is stable to the linear perturbations in all wave-lengths. As the basic form of the governing differential equations for the conventional one-dimensional two-fluid model is mathematically ill posed, it is suggested that the velocity and void distributions should be properly accounted for in the one-dimensional two-fluid model by use of momentum flux parameters.s.

In this paper, a management system of characters and roles for storytelling that is used for drama is proposed with ontology which is a key factor of semantic web. While there are few tools domestically, usage for storytelling with authoring tools is increasing outside. Especially, a study for the management system of characters. roles and casting is not performed. This study proposes a system to control a series of works related with them. It contributes to poor domestic environment of writing, which makes it systematically. Also, it applies semantic web technology by defining ontology.

A simple and convenient device for deflection-type direct reading the variations in electrolytic conductance is described and applied to the analysis of sulfur by combustion-$H_2O_2$ oxidation method. The apparatus consisted of a high resistance-ratio bridge in which the other adjacent arms are the differential cells. By adopting unusually high a-c voltage source for the bridge excitation, the a-c method for unbalanced bridge is established, decreased sensitivity owing to reduced bridge factor, 0.01, is overcome and also the absolute sensitivity and linearity are greatly improved. Over 50% variations in impedance of the balanced cell, within 1% deviation from the linearity can be attained with a volt (rms)order of output which was detected directly with VTVM without further amplification. Analysis of the bridge shows that these useful features are natural result of the constant current character of the high source impedance generator and the performance of the device agreed with the theoretical predictions. A standard procedure for the rapid analysis of sulfur using the bridge is also given, the analytical accuracy was approximately 1%. A determination takes not more than 5 minutes.

In this paper the accumulation of local damage during the cyclic loading in reinforced high-strength concrete columns is experimentally investigated. Two identical column specimens with annular cross-section and spiral reinforcement were designed and two tests, up to failure, under the action of a constant vertical concentrated force and a time-dependent concentrated horizontal force, were carried out at the LNEC shaking tables facility. Sine type signals, controlled in amplitude, frequency and time duration were used for these experiments. The concept of local damage based on local stiffness degradation is considered in detail and illustrated by experimental results. The specimens were designed and reinforced in such a way that the accumulation of damage was predicted by dominating deformations (cracking and crushing of the concrete) while the increasing of the loading values was a dominating factor of damage. It was observed that the local damage of HSC columns has exposed their anisotropic local behaviour. The damage accumulation was slightly different from the expected in accordance with the continuum damage concept, and a partial random character was observed.

Light creates ambiance that affects our impression of space. Before the modern age, the role of light is a religious factor and a primitive state to see. In the modern space design, light is used to achieve the continuous transformation and translation of building's image. Ever-changing space is a flexible corresponding of space to its environment, caused by certain dynamic light. The space turn into some other thing from what it was before, or just changing its character. approaching men and society with different meanings. The purpose of this study is to explore the relation between light(natural and artificial) and ever-changing space through the case study. The impacts of light on ever-changing in today's space design can be summarized as follows. 1) Materialization of light in space design. Nowadays light becomes a form itself. The geometric properties of the space form playa secondary role as compared to the importance assigned to light. 2) Pixelization of space by a light effect. The impacts of digital technology on the space design have come through enhancing the 'pixelization' of the surface from which buildings are made their responsiveness and adaptability to changing needs. The surface with ever-changing lights that blur the boundary of space and expand the image of space.

The study utilizes remote sensing as the main monitoring means. With different spatial high-resolution, multichannel ASTER remote sensing image as the main information in Beijing city zone; with regional border and statistical data as auxiliary factor a study between the thermal space distribution character and the underground medium is analyzed based on the GIS logical algorithm and synthetic analysis technology. Results show thermal forming mechanism and the rule of distribution is mainly related to the underground medium and the change of the city distribution. Different underground medium has different degree and intensity influence on the thermal space distribution. Furthermore, urban greenbelt and water areas can reduce the thermal effect and large-scale greenbelt creates green island effect. In addition, Road net, residential area, population density, heat resources and so on have some positive effect on the thermal distribution, which increase the local temperature and intensity on the other hand. It is important to study the thermal distribution and its related factors, which contributes to the plan, construction and development of the city.
