Deconstruction Architecture takes various approaching ways in the plural situation of modem times while it has a common thinking way in the whole area of society, art field, etc. This plural phenomenon is expressed by collage used as a painting technique. We examine the relations of collage and Deconstruction Architecture to see what kind of space formation factor collage is applied in the Deconstruction Architecture, which can be applied to the architecture composing vocabulary, and classify the aspects that collage technique is expressed with space formation factor of Deconstruction Architecture by category. We can see that superimpositon, interpenetration, juxtaposition, scaling, open structure, undecidability, assemblage, etc. are expressed as various factors in the space of Deconstruction.

Organic EL has been expected to adopt to a new styles of technology that make flat display after Tang & Vanslyke made good electric luminescence device in late 1980s. Their studies based on multi layer structure that consists of emitting layer and carrier transporting layer using proper organic material. In this study, we made multi layer device using $Eu(TTA)_3(phen)$ as a luminescence material by PVD and investigate luminous properties of each device. But oxidization of organic layer by ITO, energy walls in both pole interface, contaminations of ITO surface, importance of protecting membrane, diffusive dimming of light to cathode organic layer, these causes of degradations are common facts of a macromolecule and micromolecule. We think these degradation caused by the impact of heat and electro-chemical factor, bulk effect and interface phenomenon, and raise a question.

In spite of significant nonlinearities even in the simplest model, some types of steady-state and dynamic behavior common for nonlinear systems have never been associated with distillation columns. In recent years, multiplicity of steady states has been a subject of much research and is now widely accepted. Subsequently, stability of steady states has been explored. Another phenomenon that. although widely observed in chemical reactors, has not been associated with models of distillation columns is the existence of periodic oscillations. In this article we study the steady-state and dynamic behavior of the azeotropic distillation of the ternary homogeneous system methanol-methyl butyrate-toluene. Our simulations reveal nonlinear behavior not reported in earlier studies. Under certain conditions, the open-loop distillation system shows a sustained oscillation associated with branching to periodic solutions. The limit cycles are accompanied by traveling waves inside the column. Significant underdamped oscillations are also observed over a wide range of product rates.

Ranula is a mucocele caused by extravasation of the sublingual gland on the floor of the mouth. The most common presentation is a cystic mass in the floor of the mouth. A portion of the sublingual gland could herniate through the mylohyoid muscle, and its extravasated mucin can spread along this hiatus into submandibular and submental spaces and cause cervical swelling. This phenomenon is called plunging ranula. A variety of treatments for ranula has been suggested and include aspiration of cystic fluid, sclerotherapy, marsupialization, incision and drainage, ranula excision only, and excision of the sublingual gland with or without ranula. Those various treatments have shown diverse results. Most surgeons agree that removal of the sublingual gland is necessary in oral and plunging ranula. Four patients with ranula were investigated retrospectively, and treatment methods based on literature review were attempted.

Cantilevers are unique statically determinate structural elements with respect to their mode of overall buckling, in that the tension flange is the critical flange under gravity loading, and is the flange that deflects greatest during overall buckling. While this phenomenon does not complicate the calculation of the lateral buckling load, either theoretically or in structural design codes, it has been shown in previous research that the influence of distortion in the elastic buckling of cantilevers is not the same as that experienced in the elastic buckling of simply supported beams. This paper extends the study of the distortional buckling of cantilevers into the hitherto unconsidered inelastic range of structural response. A finite element method for studying the inelastic bifurcative instability of members whose cross-sections may distort during buckling is described, and the efficacy of the method is demonstrated. It is then used to study the inelastic distortional buckling of hot-rolled I-section cantilevers with two common patterns of residual stresses, and which may be restrained elastically from buckling by other structural elements.

When collision accident between ships or between ship and offshore platform occurs, a common phenomenon that occurs in structures is the plastic deformation accompanied by a large strain such as fracture. In this study, for the rational design against accidental limit state, the plastic material constants of steel plate which is heated by line heating and steel plate formed by cold bending procedure have been defined through the numerical simulation for the high speed tension test. The usefulness of the material constants included in Cowper-Symonds model and Johnson-Cook model and the assumption that strain rate can be neglected when strain rate is less than the intermediate speed are verified through free drop test as well as comparing with numerical results in several references. This paper ends with describing the future study.

Sudden esophageal obstruction by a bolus of food is not a rare phenomenon. The individual is frequently elderly and has ill-fitting dentures through others may initiate this by bolting food. In adult patient there is a frequent history of alcoholic intake, the consumption of meat with improper chewing. A common anatomic abnormality leading to meat impaction of the esophagus is hiatal hernia, which is often associated with a ring or stricture. Recently authors experienced a case of repeated esophageal foreign bodies in 10 days in the patient who had esophageal stricture.

The purpose of this the end of 20th century fashion about various phenomenon of distopia. This study have the analysis and consideration through the elements and peculiarity of distopia. This study give us the various figures of distopia st fashion as well as the common features of distopia. The study method refers to sundry records, thesis, fashion magazine, publication, the collection works and internet. It is as follows. 'Distopia' prefix to dis of Utopia and means unknown future. Distopia trends towards future negatively. The end of 20th century, it is well brought out various cultures. Movie, novel and pop culture have effect on end of the 20th fashion with a view of distopia. It is the fear and uncertainty of the future. The characters of distopia through the works are divided into formative characteristics and aesthetics meaning. The future fashion of distopia expression mixed and various cultural life, also the mixed of utopia and distopia fashion. Distopia stimulates the designers to the new expression and expose their new areas.

The purpose of this study was to investigate males' and females 'experiences of violence and to determine what variables served as predicting indicators among unmarried college students. The major findings were as follows; 1. Those who sustained psychological agression were 61% physical violence 43% and sexual violence 22% As the sample indicates victimization of dating violence among college students is a common phenomenon.2. More males sustained the severe from of physical violence and the sexual violence than females did while both sexes reciprocally sustained psychological aggression. 3. For males significant predictors of sustaining dating violence were conflicts inthe dating relationship and witness of interparental aggression while for females conflicts in the dating relationship a need to control one's partner and school violence served as significant predictors.
