China has been aware of the urgent need of developing electronic and information industry in order to improve its productivity. Since 1991, IT industry has been one of the main factors to influence China's economic growth. In the results of the efforts to develop its IT industry, China has achieved average 25% yearly growth rate of IT manufacturing industry since 1991. We will take a look at haw the main IT products' performances was, how the role of IT industry was in China economy and in China's trade and how the prospect of China IT industry will be. However, we need to know that, depending an the different areas, the environment of the China's IT industry will be quite different. In China, the east coastal area has the better environment of technology, menpower, infrastructure, and fund for the development of IT industry and the IT industry of this area is very competitive, comparing with the middle and west area.

The characteristics of construction work cause excessive strain on specific body parts of the construction craft workers. However, there are few tools to mane an accurate measurement of the load on the musculoskeletal system, and the musculoskeletal disorders (MSDs) experienced by the workers have not been properly understood. So, there is an urgent need for development of a tool to measure the load on the musculoskeletal system. Therefore, this research aims to develop a musculoskeletal load measuring device for construction workers. In order to eliminate the noise and errors, an accelerometer, gyro sensors and the Kalman Filter are used in the device developed in this research.

Recent government policies are increasing interest in zero-energy housing, a building that minimizes energy consumption (90% reduction). As the importance of building passive performance is emphasized, the role of insulation is increasing as a way to reduce indoor heat loss in order to minimize the use of cooling and heating energy. There are two main types of insulation. Organic insulation is widely used for various construction structures such as construction and industrial due to some merits such as the convenience of construction and construction cost. However, it has been pointed out as a main cause every time a fire accident occurs, Jecheon Sports Center', the fire damage of buildings caused by the use of organic insulation materials is expanding to social problems, so it is urgent to research on nonflammable inorganic insulation materials.

This study is initiated to solve the problem that the development of an electric machine to drive heavy horse-power load required in the rural district, where only single phase supply is available, is very urgent. As a method for this purpose, the single/three phase converter by single phase induction machine with a tapped auxiliary winding, running unloaded mechanically under single-phase source and supplying three-phase output to a loaded 3-phase induction motor, is devised and the pilot machine is put into test. Analysis based on hybrid equivalent circuit for the phase converter and symmertical component theory for the 3-phase load motor and practical experiment result in that optimum auxiliary winding ratio is to be 1.25 rather than theoretical .root.3/2 in order to keep the voltage unbalance ratio of 3-phase output from the converter as low as possible in both cases of starting and running the load motor.

It is urgent to introduce home visiting physical therapy in order to prevent the unnecessary increase of demand and extravagance for the nation-wide execution of medical insurance and for the medical demand and supply of medical delivery system. We think that it is very important for us, as a physical therapist preparing 21 centry, to clearly undersand the necessity of home visiting physical therapy, which will be needed as the new therapeutic field in the future. When the terms for a new health and medical system, that is, useful trained-manpower, well-equipped facilities, financial and legal support, well-prepared design for this project, positive cooperation between people involved in this project and rational development of the project is held and this project is settled by sieving tile expected problems, this project will give a contribution to the promotion of national health and social welfare

Total accident rate in the construction industry is a very meaningful reduction to establish a comprehensive disaster reduction measures, including through the Survey, the disaster prevention projects whilst driving status and problem analysis in order to reduce the mature workers in the construction industry is growing rapidly in all disaster disasters (share) The days. It is urgent to establish a framework and measures that can identify the specific cause for this than for the middle-aged workers and disaster reduction in disaster reduction efforts, which continue to increase. Used as measures of information and data presented in the basic requirements of mature workers also been.

According to the research of the cultivation result on the spot farmers for 5 years in order to investigate its cultivation conditions and problems of Lycium chinense Mill, the development of the variety with early mature, pest tolerance, and high yielding is urgent and it is call for the development of rooted cutting cultivation by testing of bed soil, growth regulator and cutting times. The development of cultivation method with planting year, planting density, supplementary period and amounts of supplementary of Lycium chinense Mill planted in growing field are required and for the disease and the effective control of disease and insect pest resistance is needed by auxotrophic fertilizing and organic agricultural method, met by agricultural chemicals.

Recently, in order to stay at predominance in the global infinity competition, most of companies have been reducing the cost in many fields of industry First of all, the reduction of the logistics cost have been recognized greatly as the company value rises. But, the current situation of domestic logistics cost is very weak compared with Japan, U.S.A., etc. A rate of logistics cost out of GDP is still high compared with the competitors. The reduction of the transportation cost from overall logistics cost is most urgent subject. One of the methods to make a domestic transportation system efficient is the consolidation. In this paper. we try to compare the consolidated transportation model for a cost reduction with individual case. We also analyze the efficiency of consolidated transportation using simulation program with Arena of System Modeling Company.

Trying to give an overview of home informationization accelerated by the information age, the main purpose of this research is to suggest a guide for home Economics to adjust to the era. While the informatinization in home provides convenience and plays a major role to improve the quality of the life there are still many problems to be reflected on. First of all in order to utilize a variety of information devices it is needed that technical index related to home management such as home information device index and the expenditure on information is studied. Secondly, it is needed to predict possible home life style in the future and build up the ability to adjust to the change. Therefore, in the field of home economics, developing programs to offer the better chance of education on home life and culture, values, relationships, capability to enhance home life etc, is in urgent need of reflection.

Vietnam is entering an important phase of urbanization that corresponds to the current economic development. Developing logistics of Vietnam in general, and Haiphong particularly, is urgent in order to meet the need for the economic development of Viet Nam in this period of international integration. Hai Phong's development record over the past 20 years is remarkable. In conjunction with the local government's efforts, external factors, such as increasing direct foreign investment, is turning Hai Phong into Vietnam's logistics hub. However, even though Hai Phong accounted for 98% of North Vietnam's throughput, its logistics services are low level, the ports are fragmented, and the port management scale is backward, with the legal system overlapping. This paper has systematically evaluated the development of Haiphong city during recent years, then offers some solutions to develop logistics for Hai Phong ports.
