The National Living Halls in commemoration of the Olympic games are acknowledge as a living space for all the people. These halls were established and have been operating in 15 cities and provinces, one hall each, throughout the country. However, it seems somewhat insufiicient for many people to join in. In the future, the Government shall have to construct gymnasiums by the unit of Shi(city)/Gun(county) in a level of pormoting national prosperity through physical culture. Meanwhile the National Living Halls shall have to develop a new program suitable to regional conditions, and popularize it. In management, scientific management of system and execution outside the budget are required. Improvement of office workers service and modernization of facilities are required.

The automatic operation of production in industrial society is a necessary facilities. Numerical Control machine tool is also the basic part of productive facilities system. The study, which is one way of program by educational-industrial complex so as to realize copy machine, CND-Index(Turbo-Ix5C), into a detailed position control in 1[mm]and the automatic operation of a uniform copy machine, makes the position control in 1[mm]possible.
내부 열경계조건을 고려한 채란 계사시설의 수치해석적 연구

In this paper, the numerical study to predict air flow patterns and thermal environment characteristics in a window-less laying hen house was performed. The numerical model of this study was calculated with parameter for inlet velocity, inlet temperature reflecting upon interface thermal boundary condition. With 2.5% error, the calculated temperature distributions was predicted very well. Numerical results show that the case of 20∼23℃ inlet temperature with 7 ㎧ inlet velocity was better thermal environment condition. The results of this numerical study reflecting upon interface thermal boundary condition will be very useful for predicting thermal environment characteristics in laying hen house.

The high speed precision spindle, which is an important element part of industrial machinery such as micro drilling, high speed machine tools and the atomizer. In this study, the aero-static spindle was designed and a stiffness analysis of air bearing was carried out to investigate the optimal design parameter for the high speed spindle.

This paper presents a methodology to include such latent factors as explanatory variables. The stated preference survey SP data-to observe the mode choice behavoir are carried out in the Sor-Ak and Kyer-Yong mountains. The new model of mode choice behavior which is introduced the latant variables, LISREL model, was developed by the SP data using the LISTEL package. Accessibility and level of service on road in the tourism region are of important for increasing the attractiveness index. As a result, the new model of mode choice shows good accuracy more then other model. The result will be use to transportation planning and operation for increasing the attractive index in the tourism regional.

In this paper, the RF system of the W-CDMA receiver is analyzed and designed. In order to obtain precise receiving performance parameter, we calculated each parameter which complied with specification(3GPP TS 34.121 V3.2.0). Noise Figure(NF) which is key parameter of receiver is derived from the specification. Linear characteristic and noise characteristic of the receiver system are analyzed by Phase Noise(PN) and Third Order Intercept Point(IP3) respectively. In addition, sweeping of the nonlinear component parameter which affects the linear performance is examined. Finally, we designed RF system which follows the available maximum parameters and introduced it in each part.

Emerging technologies such as Cybercash, E-cash and Smart Cards can be expected to change payment mechanisms, reduce demand for central bank money. This paper studies the process and effect of electronic money and banking. The monetary policy implications of electronic money are uncertainty over security, standards, and the potential to replace central bank currency and banking supervision.

This investigation was conducted to study the effect of bond and slip of reinforcing deformed bars in steel fiber concrete. The experimental study were made to compare the resistance to slip deformed bars in non mixed with steel fiber concrete and mixed with steel fiber concrete through pull-out test in this paper. The capacities of bond and slip of deformed bars in mixed with steel fiber concrete are discussed. The conclussion are as follows. (1) The maximum bond stress increase with the increase of the compressive strength of the concrete. (2) The value of μ_amax/_cσ_c decrease with the increase of compressive strength of the concrete (3) The maximum bond stress of concrete increase with the mixed with steel fiber compare to non mixed with steel fiber.

The paper describes the development of a new automatic wrapping machine using paper films as it has not been used so far. The most of the automatic wrapping machine have used the vinyl film causing environmental pollution, the paper films, however, have a weak point in the aspect of high temperature adhesion. Therefore, the mechanism of the existing wrapping machine should be altered to prevent it from curling effect through the technical know-how. A new method and technology reducing the curling effect in the automnatic wrapping machine are demonstrated by using developed blower. Thus it is exqection and will decrease environmental pollution.
