This paper proposes a new training system for equilibrium sense and postural control using unstable platform and force plate. This system consists of unstable platform, force plate, computer interface, software and the computer. Using this system and training programs, we perform the experiment to train the equilibrium sense and postural control of subject. To evaluate the effects of balance training, we measured some parameters such as the maintaining time in the target, the moving time to the target and the mean absolute deviation of the trace before and after training. The result shows that this system can improve the equilibrium sense and balance ability of subject. This study shows that proposed system had an effect on improving equilibrium sense and postural control and might be applied to clinical rehabilitation training as a new effective balance training system.

In this paper, we consider a new preventive replacement policy for the system which deteriorates while it is in operation with an increasing failure rate. The system is subject to two types of failure. A type 1 failure is repairable while a type 2 failure is not repairable. In the new policy, a system is replaced at the age of $t_p$ or at the instant the$\textsc{k}^{th}$ type 1 failure occurs, whichever comes first. However, if a type 2 failure occurs before a preventive replacement is performed, a failure replacement should be made. We assume that a type 1 failure can be rectified with a minimal repair. We also assume that a replacement takes a non-negligible amount of time while a minimal repair takes a negligible amount of time. Under a cost structure which includes a preventive replacement cost, a failure replacement cost and a minimal repair cost, we develop a model to find the optimal ($\textsc{k},t_p$) policy which minimizes the expected cost per unit time in the long run while satisfying a system availability constraint.

In is a recent trend of the world to study the integrated science curriculum development. This study aims at pursuing how to integrate physics and earthscience in high school course and forming a tentative plan as to an integrated process between both the subjects. The one was compared with the other accor ding to the basic concepts and theteaching objecties. The contents of these two subjects were analysed, the overlapping parts being chosen, and so in the hierachy of the curriculum, some mistakes were found in eaching these two two subjects. It proved valid to in tegrate these two subject. A concrete scheme was offered to in tegrate these two subjects-physics and earthscience, when a tentative plan concerning, the integra ted process was made. This new plan can make the time required for teaching decrease by 5% The better study on the basic structure of the integrated concepts between these two subjects will go on further in this respect. It is necessary to train again the teachres concerned with this new subject and to put an emphasis on the elective course between physics and earthscience in the teacher's college curriculum.

As the NCS(National Competency Standards) classification system continued to be developed and supplemented, NCS became widespread. Qualifications were redesigned to actively reflect industry demands, reduce the burden of redundant acquisition of unnecessary qualifications, and to evaluate objective capacities of the workforce. In addition to the learning modules to be developed in the future, previously developed NCS-based learning modules and lectures should be reorganized based on the new qualification design. In this paper, the Java programming subject designed based on NCS was redesigned according to SW new qualification design. Since the redesigned Java programming subjects consider the qualification design direction or qualification roadmap, not only can they be recognized as a test subject in qualification assessment through course evaluation, but also can be used as individual qualification data.

The purpose of study suggest that new strategies available for the physical therapy curriculum development are trying to elicit from world-renowned universities those to keep pace with the globalization. The curriculum of 3 universities in Australia was compared with those of a four-year course in Korea. The 3 university are Sydney, Melbourne and Queensland Universities in Australia. Overall, the curriculum in Korea not only showed overlapping subjects, a shortage of clinical time and foundation science but, didn't deal with many subject to satisfy international recommendation. We suggest that a new curriculum should be based on the three parts which are foundation, essential divided into 6 areas and selection subject, particularly extended clinical experience to essentially need to be physical therapy in the world-standard.

This paper presents an elastic/plastic model that neglects strain hardening during loading, but accounts for the Bauschinger effect. These mathematical features of the model represent reasonably well the actual behavior of several materials such as high strength steels. Previous attempts to describe the behavior of this kind of materials have been restricted to a class of boundary value problems in which the state of stress in the plastic region is completely controlled by the yield stress in tension or torsion. In particular, the yield stress is supposed to be constant during loading and the forward plastic strain reduces the yield stress to be used to describe reversed yielding. The new model generalizes this approach on plane stress problems assuming that the material obeys the von Mises yield criterion during loading. Then, the model is adopted to describe reversed yielding in thin hollow discs subject to external pressure.

The meticulous figure painting is one of the wonders of traditional Chinese painting and has blossomed in art history with its unique and interesting style. The period from the Warring States period to the Song and Yuan dynasties was a glorious period in its history, after which it tended to decline due to changes in painting materials and many socio-historical reasons. The extensive cultural exchanges in the world today, the penetration of Western values and the expansion of information technology have brought a huge impact on Chinese meticulous figure painting, which has developed an active way of thinking and expression after absorbing certain elements of Western culture and thought on the basis of inherited tradition. Contemporary Realistic Figure painters continue to explore new developments in meticulous figure painting in the contemporary context, and give contemporary meticulous figure painting a new cultural and ideological connotation, forming a new look that meets the requirements of the times, with richer and more lively content, subject matter and formal language. Traditional meticulous figure painting is characterised by a highly refined use of line and coloring composition. Contemporary meticulous figure painting focuses on the use of purely formal language and the expression of the personality of the creative subject, with a new outlook on the world of painting. In the contemporary multicultural context, new formal language and methods of expression are constantly being explored to create a new look. In the process of development, contemporary meticulous figure painting has merged the best qualities of traditional and contemporary culture, making it an art with a subtle language, rich in meaning and with the charm of the times and oriental characteristics. The author in the form of contemporary fine brushwork figure painting language as the research object, explore new form of fine brushwork figure painting, and in the contemporary society and multicultural context factors. Innovation, enrich and develop new forms of art language of contemporary social form and aesthetic temperament and interest.
