  • This study suggests the popular culture theory as a basic framework to find out the characteristics of contemporary fashion show meeting the popular culture, and describes that the show is the popular culture of this generation. The culture is the way of our life unifying the world at common area of human being. The popular culture is to subdivide it into the public culture that shares aesthetic taste, and to borrow each other and develop it mutually because of the collapse of dichotomous boundary with high quality culture, and to represent the people’s thought and behaviour expanding their areas. The author has examined the characteristics of popular culture of modern fashion show by four collections, that is, commercialism, mass media, political relationship and interaction, etc: Firstly, at the commercialism, the fashion show combines it with other genre organically to do mass production and sales and produces cultural consumption goods supplying a lot of sight-seeing. Secondly, at the mass media, the image of contemporary fashion show has been spread out with mass media such as fashion magazines, cable TV and Internet beyond time and space to produce advertisement effects and makes new fashion and bring democratic culture. Thirdly, at political relationship, the fashion in its peak can make a big stream of wealth, so that it plays important roles under governmental regulations in this era and governments make efforts to support and develop it. Lastly, at interaction, the fashion show shares media functions to let users participate in the program and to exchange information as a feedback to influence each other.

  • VATS is now used by many thoracic surgeons and in various anatomic locations such as lung parenchyme, pleura and mediastinum, etc. VATS of mediastinal masses has special characteristics compared to that of other diseases. Those are no positional changes of the mass during collapse of the lung and close proximity of the mass to major vascular structures, nerves and other vital organs. From 1992. July to 1993. August, 10 mediastinal masses were treated with video assisted thoracoscopy. There were five males and five females, ages ranged from 11 years to 65 years with average 37.7 17.7 years old. Of the 10 patients, 4 were bronchogenic cysts, 2 were teratoma, and the others were thymoma, neurilemmoma, pericardial cyst, and thymic cyst. Needle aspiration was done in large cysts and the working thoracotomy[or utility thoracotomy] was done in large solid masses for the purpose of easy dissection, easy handling and easy delivery of the mass. The average operation time were 155.6 6.8 minutes and the duration of air leakage were 1 2.2 days. The duration of the chest tube drainage were 3.3 2.6 days. The lengths of the postoperative hospitalization were 5.1 2.7 days which were shorter than those of 12 mediastinal masses treated with conventional thoracotomy during the same periods [p<0.05]. There was 1 patient converted to thoracotomy because of a bleeding at innominate vein. 3 postoperative complications were occured. Those were persistent air leakage for 7 days, diaphragmatic palsy and hoarseness which were recovered within 1 month. We conclude that mediastinal mass can be excised with video assisted thoracoscopy and the posthospitalization is reduced. But careful attention is required for avoiding injury to major vascular structures, nerves, and other vital organs.

  • In event of a tunnel fire, all kinds of equipment can be destroyed in high temperature that can exceed $1300^{\circ}C$, fatal structural demage can be caused by spalling of concrete structural elements. To make matters worse, there is a high possibility of the secondary damage which can lead to the collapse of the shear resisting structure. Accordingly, it is time that we developed the technology to counter fires in connection with the fire-resistant design of a tunnel structure. To secure the reliability of the fire-resistance performance of a tunnel structure, it is necessary to assess the fire's behavior on every structural element exposed to the fire as well as to calculate the tunnel fire intensity and the quantity of heat released. In this study, we drew out the fire damage range of each structural element of a tunnel and the minimum thickness of concrete cover for each fire-resistant material through some actual experiments of fire behavior on the structural elements of a tunnel.

  • Overloading of Commercial vehicles have been an important area of transportation as one of the main causes of pavement damage, bridge collapse, severe traffic accident, etc. In this study, we analyzed the effects of overweight prevention by analyzing overweight driving patterns and using weight sensors. First, we analyzed relevant literatures of overweight and surveyed the commercial weight sensors. Then we chose the typical type of overweight vehicles based of overweight enforcement data analysis. MEMs inclinometer weight sensor were installed to 10 test vehicles and data was collected by weight sensors and gps in real time. As a result of gross vehicle weight and axle weight analysis, it was found weight sensor could decrease overweight rate. However, since the number of samples of test vehicles is insufficient to represent the whole commercial vehicle, further studies are deemed possible through the extension test.

  • Dose calculation algorithms play an important role in radiation therapy and are even the basis for optimizing treatment plans, an important feature in the development of complex treatment technologies such as intensity-modulated radiation therapy. We reviewed the past and current status of dose calculation algorithms used in the treatment planning system for radiation therapy. The radiation-calculating dose calculation algorithm can be broadly classified into three main groups based on the mechanisms used: (1) factor-based, (2) model-based, and (3) principle-based. Factor-based algorithms are a type of empirical dose calculation that interpolates or extrapolates the dose in some basic measurements. Model-based algorithms, represented by the pencil beam convolution, analytical anisotropic, and collapse cone convolution algorithms, use a simplified physical process by using a convolution equation that convolutes the primary photon energy fluence with a kernel. Model-based algorithms allowing side scattering when beams are transmitted to the heterogeneous media provide more precise dose calculation results than correction-based algorithms. Principle-based algorithms, represented by Monte Carlo dose calculations, simulate all real physical processes involving beam particles during transportation; therefore, dose calculations are accurate but time consuming. For approximately 70 years, through the development of dose calculation algorithms and computing technology, the accuracy of dose calculation seems close to our clinical needs. Next-generation dose calculation algorithms are expected to include biologically equivalent doses or biologically effective doses, and doctors expect to be able to use them to improve the quality of treatment in the near future.

  • This paper aims at investigating Dorothy Wordsworth's later conversation poetry, which has not been the focus of critical discussions on her literary works. While many critics have been emphasizing Dorothy Wordsworth's journals and the tendency of self-effacement in her prose, this paper argues that her later poetry often reveals acute self-consciousness about the circumstances that condition this self-annihilation and searches for a creative way to endorse her own identity. In "Lines Intended for My Niece's Album," she expresses anxiety and uncertainty about the inclusion of her poetic piece in Dora Wordsworth's album, which contains poems by prominent male writers of the contemporary period. "Irregular Verses" presents Dorothy Wordsworth's self-conscious narrative of her girlhood and shows how her own ambition to become a "Poet" has been stifled by external circumstances, including the ideology that instills the idea of proper womanhood into aspiring girls. While these poems examine contemporary gender discourse and the frustrated poethood resulting from it, other poems activate conversations with William Wordsworth's poems and thereby provide a revisionary re-writing of her brother's texts. For example, in "Lines Addressed to Joanna H." Dorothy Wordsworth becomes "a woman addressed who herself addresses others." Her scrupulous approach to her own addressee refuses to subordinate the other to the self's will, and through this revision of "Tintern Abbey," Dorothy Wordsworth vicariously liberates her own self confined in her brother's poems. "Thoughts on My Sick-Bed," which echoes "Tintern Abbey" through borrowed phrases and direct address to William Wordsworth, foregrounds her own poetic identity in the form of the first-person pronoun "I." Dorothy Wordsworth's continual illness during this period of her life paradoxically allows her the time for personal reflection formerly denied to her in her busy life constantly occupied by physical and spiritual labor for others. Instead of earning satisfaction from the subsumption of her creative energy under William Wordsworth's poetical endeavor, Dorothy Wordsworth finally starts to affirm her own poetic identity that can properly express her inner vision and artistic talent. Although this final affirmation remains largely incomplete due to her later mental collapse bordering on madness, it powerfully conveys the hidden literary aspiration of the formerly frustrated female poet.

  • It is of great importance to be able to evaluate different structural systems not only based on their seismic performance but also considering their lifetime service costs. Many structural systems exist that can meet the engineering requirements for different performance levels; therefore, these systems shall be selected based on their economic costs over time. In this paper, two structural systems, including special steel moment-resisting and the ordinary concentric braced frames, are considered, which are designed to meet the three performance levels: Immediate Occupancy (IO), Life Safety (LS), Collapse Prevention (CP). The seismic behavior of these two systems is studied under three strong ground motions (i.e., Tabas, Bam, Kajour earthquake records) using the Perform3D package, and the incurred damages to the studied systems are examined at two hazard levels. Economic analyses were performed to determine the most economical structural system to meet the specified performance level requirements, considering the initial cost and costs associated with damages of an earthquake that occurred during their lifetime. In essence, the economic lifetime study results show that the special moment-resisting frames at IO and LS performance levels are at least 20% more economical than braced frames. The result of the study for these building systems with different heights designed for different performance levels also shows it is more economical from the perspective of long-term ownership of the property to design for higher performance levels even though the initial construction cost is higher.

  • The traditional double story isolated structure is a derivative of the base isolated and inter-story isolated structures, while the new double story isolated structure represents a novel variation derived from the traditional double story isolated structure. In order to investigate the seismic response of the new double story isolated structure, a comprehensive structural model was developed. Concurrently, models for the basic fixed, base isolated, inter-story isolated, and traditional double story isolated structures were also established for comparative analysis. The nonlinear dynamic time-history response of the new double story isolated structure under rare earthquake excitations was analyzed. The findings of the study reveal that, in comparison to the basic fixed structure, the new double story isolated structure exhibits superior performance across all evaluated aspects. Furthermore, when compared to the base isolated and inter-story isolated structures, the new double story isolated structure demonstrates significant reductions in inter-story shear force, top acceleration, and inter-frame displacement. The horizontal displacement of the new double story isolated structure is primarily localized within the two isolation layers, effectively dissipating the majority of input seismic energy. In contrast to the traditional double story isolated structure, the new design minimizes displacements within the inter-isolation layer situated in the central part of the frame, as well as mitigates the overturning forces acting on the lower frame column. Consequently, this design ensures the structural integrity of the core tube, thereby preventing potential collapse and structural damage.

  • The stability and structure of bluff-body stabilized hydrogen flames were investigated numerically and experimentally. The velocity of coflowing air was varied from subsonic velocity to a supersonic velocity of Mach 1.8. OH PLIF images and Schlieren images were used for analysis. Flame regimes were used to classify the characteristic flame modes according to the variation of the fuel-air velocity ratio, into jet-like flame, central-jet-dominated flame, and recirculation zone flame. Stability curves were drawn to find the blowout regimes and to show the improvement in flame stability with increasing lip thickness of the fuel tube, which acts as a bluff-body. These curves collapse to a single line when the blowout curves are normalized by the size of the bluff-body. The variation of flame length with the increase in air flow rate was also investigated. In the subsonic coflow condition, the flame length decreased significantly, but in the supersonic coflow condition, the flame length increased slowly and finally reached a near-constant value. This phenomenon is attributed to the air-entrainment of subsonic flow and the compressibility effect of supersonic flow. The closed-tip recirculation zone flames in supersonic coflow had a reacting core in the partially premixed zone, where the fuel jet lost its momentum due to the high-pressure zone and followed the recirculation zone; this behavior resulted in the long characteristic time for the fuel-air mixing.
