The convergence characteristics of an LMS type Equalizer whose coefficient are multiple adapted in a symbol time period by recycling the received data are analyzed. The theoretical analysis shows that the data-recycling LMS technique can increase convergence speed by (B+1) times, where B is the number of recycled data. The results of the computer simulation demonstrate that the simulation results are in accordence with the theoretical analysis and the superiority of the equalizer algorithm.

This study has adapted a genetic algorithm for an optimal design for the first time. the models that was used a simulation are the first and second order response surfaces model, Using an genetic algorithm in D-opimal it is more efficient than previous algorithms to get an object function. Not like other algorithm without any restrictions like troublesome about the initial solution not falling into a local optimal solution it's the most suitable algorithm.

The purpose of this study was to investigate the influences of informazation on the structure of family life. This study adapted the theory of family life structure to analyze these influences. this theory viewed the components of family structure as ‘family culture’, ‘means for living’, ‘household management’, ‘family relations’, ‘time’, and ‘living space’. Related research works conducted in the several disciplines and the statistics were used, The informazation had great impacts on the structures of family life. Some impacts wre desirable but undesirable impacts were also found. Some recommendations were made improve the quality of family life in the society of informazation.

The previous quantitative bankruptcy prediction models cannot include time dimension. To overcome this limit, various dynamic models using survival analysis are developed recently. This paper emphasizes that the proportionality assumption must be adapted with caution when the Cox's proportional hazard model is used to explain bankruptcy. It is shown that a non-proportional hazard model including a change point model is a proper alternative, when the proportionality assumption is violated by the change of macroeconomic environment, such as the financial crisis in 1997.

Waste body settlement is an important aspect of management of landfill sites both during the operational and the post-closure phases. Settlement in landfill waste is caused by combination of load, creep and biodegradation induced effects. In this paper, settlement characteristics of closed waste landfill were studied by analyzing in situ measured data and computer simulation technique. Techniques for the analysis of load-induced and creep settlement, and for their implementation, can be adapted for landfill waste. The estimate of settlements from models shows a increase according to time.

Kanban, a pull system for inventory control is in direct contrast to conventional push systems. In the pull system, the kind and quantity of items needed by the succeeding stage are withdrawn from the preceding stage, only at the rate and at the time they are consumed. In this paper, lot size models are formulated in two special cases of practical interests and simple solution procedures are adapted to minimize the total cost of the kanban system. An numerical example is solved to illustrate the method.

This paper presents a framework for seismic damage evaluation for Algerian buildings adapted from HAZUS approach (Hazard-United States). Capacity and fragility curves were adapted to fit the Algerian building typologies (Reinforced Concrete structures, Confined or Non-Confined Masonry, etc). For prediction purposes, it aims to estimate the damages and potential losses that may be generated by a given earthquake in a prone area or country. Its efficiency is validated by comparing the estimated and observed damages in Boumerd$\grave{e}$s city, in the aftermath of Boumerd$\grave{e}$s earthquake (Algeria: May $21^{st}$ 2003; $M_w$ = 6.8). For this purpose, observed damages reported for almost 3,700 buildings are compared to the theoretical predictions obtained under two distinct modelling of the seismic hazard. In one hand, the site response spectrum is built according to real accelerometric records obtained during the main shock. In the other hand, the effective Algerian seismic code response spectrum (RPA 99) in use by the time of the earthquake is considered; it required the prior fitting of Boumerd$\grave{e}$s site PGA (Peak Ground Acceleration) provided by Ambraseys' attenuation relationship.

Korea Furniture design development process is repeated a number of changes by the change of residence and type of market demand derived from the process of industrialization. The modernization process of industrialization advances by large-scale population moves to the city to urbanization proceeds rapidly. Housing problems are concentrated in cities and sparked the furniture industry, furniture design by changes in marketing concepts that appear in the industrialization phase, growth must necessarily accommodate the needs of consumers. Including kitchen furniture, living room furniture and master bedroom furniture has been sensitively adapted changes in the structure of these houses, particularly structural changes Apartments. Starting in the 1990s, jumping over furniture industry has adapted quickly to the market demand, changes in marketing concepts. Furniture industry is growing market share in most of the country, but the entire industry had to undergo a competitive marketing overheating due to excessive supply in excess of market demand since the mid-1990s. Changes in furniture design in this process was the change in furniture design more than the change of the residential structure. The study industrial development and marketing concepts are changing to construct a model to track the changes varied styles and time changes affect whether the main furniture design.

To cope with channel variation, wireless networks such as IEEE 802.11 WLAN provide multiple transmission rates by employing different channel modulation and coding schemes. However, the coexistence of different transmission rates degrades the total system performance of the network. In order to eliminate this performance abnormality and improve protocol capacity, we propose a new Packet transmission algorithm, the RAT(Rate-Adapted Transmission) scheme. The RAT scheme distributes the wireless channel fairly based on the channel occupancy time. Moreover, it efficiently transmits packets even in a single station using rate-based queue management. Therefore, the RAT scheme obtains not only the inter-rate contention gain among stations but also the intra-rate contention gain among connections in a single station.

Through the whole period of the twentieth century, Chinese Traditional Medicine has been affected by the political and cultural changes of Chinese society. Before the 1949 Communist Revolution, Chinese Traditional Medicine was regarded as a dark past which should be cleared off. But Chinese Traditional Medicine has been reevaluated as a national medicine and spreaded quickly since the 1949 Communist Revolution. Moreover, 'the bare foot doctor' who received short term training appeared during the Cultural Revolution. It enhanced the status of Chinese Traditional Medicine. At the same time, it was estimated as a model of the self-reliant development of Third World countries. But the direction of development of Chinese Traditional Medicine was changed again recently. Chinese government has adapted the open-economy policy since the late 1970s. Accordingly Chinese Traditional Medicine also has been changed. Nowadays it pursues the professional development strategy. This paper inquired the following research questions. First, what kind of historical changes in the development strategy of Chinese Traditional Medicine has happened? Second, how much Chinese Traditional Medicine has accomplished the professionalization? Third, what kind of problems Chinese Traditional Medicine has met in the process of professionalization? Finally, why Chinese Traditional Medicine has adapted the professional development strategy?
