Currently, with the development of an advanced industrial form, attention to human life has risen gradually. On the basis of aboves, Oriental medical industry has been achieved revolutionarily, and moreover the new word 'Well-being' has been born due to the value of life and attention to health. All who live in the 21-century have worried about problem with health and well-being, and the substitute medical science centering around the Oriental medicine has come up as the major concern, not to speak of the Oriental the West. Domestically, Research and attention to the Oriental medicine has increased, and its importance has appeared. At the moment, locally self-governing groups have taken an active step to study the genetic resources centering around locally- breedy wild medicinal herbfor their economy growth. Accordingly, in the historic view, to discover our medicinal herb's essence and to supply professional, systemical infomation of herb genetic, the necessity of professional exhibition museum can come up. under the above circumstances, I propose the public information museum in local area.

The liquid crystal device with switchable dynamic mode and memory mode has been investigated and developed. The proposed device reveals splay, ${\pi}$ twist and bend states by selective switching among them. In the dynamic mode, this device is operated in the bend state which exhibits the wide view angle and fast response time properties due to the self-compensated bend structure and flow accelerated fast response time. In the memory mode, the permanent memory characteristics in the splay and ${\pi}$ twist sates are obtained, respectively. The switching mechanisms of the tristate device are also proposed.

This paper presents an experimenal proof for criteria of selecting an optimum adaptive beamforming (ABF) algorithm for a large distorted phased array. A single point target embedded in clutter model is suggested to compare four well-known ABF algorithms. These algorithms are tested to low variance and high variance real data for self-calibrating a large distored phased array. It is shown that these algorithms require at least one dominant scatterer with large radar cross section (RCS) or multiple scatterers with moderate RCS in the field of view. Experimental results are provided to demonstrate the comparisons of the four algorithems in terms of gain loss and image correlaion coefficient, along with corresponding reconstructed cross-range images and range-azimuth images.

Conventional vector quantization (VQ) codebook design methods have several drawbacks such as edge degradation and high computational complexity. In this paper, we first made activity coordinates from the horizonatal and the vertical activity of the input block. Then it is mapped on the 2-dimensional interconnected codebook, and the codebook is designed using kohonen self-organizing map (KSFM) learning algorithm after the search of a codevector that has the minumum distance from the input vector in a small window, centered by the mapped point. As the serch area is restricted within the window, the computational amount is reduced compared with usual VQ. From the resutls of computer simulation, proposed method shows a better perfomance, in the view point of edge reconstruction and PSNR, than previous codebook training methods. And we also obtained a higher PSNR than that of classified vector quantization (CVQ).

Hidden line removal(HLR) algorithms can be devised either in the image space or in the object space. This paper describes a hidden line removal algorithm in the object space specifically for the CAD viewer data. The approach is based on the Appel's 'Quantitative Invisibility' algorithm and fundamental concept of 'back face culling'. Input data considered in this algorithm can be distinguished from those considered for HLR algorithm in general. The original QI algorithm can be applied for the polyhedron models. During preprocessing step of our proposed algorithm, the self intersecting surfaces in the view direction are divided along the silhouette curves so that the QI algorithm can be applied. By this way the algorithm can be used for any triangulated freeform surfaces. A major advantage of this algorithm is the applicability to general CAD models and surface-based visualization data.

International transfer of technology is not a simple mechanical progress obtaining technology from overseas, but a sysmetic progress for advancing ability of domestic research development through technology, men of talent, advanced management and its experience. In this progress, it is a important yardstick measuring a country's standard of technology & productivity and self-reliance of industrialization whether countries have introduced some technologies or settled them somehow or not. Through these views, this paper is dealing in major features on each stage in connection with economic system's change, strategy of economic development and industrialization of China regarding transfer technology in China extended during five decades after war.

An Ethnographic Decision Model (EDM) to explore socioeconomic, cultural, and psychological factors related to the attitudes toward childless family was developed in this study. From college students' protocol writings, this research found that the participants in general had conservative views about childless families. They tended to simplify childless families as either infertile couples or DINK (Double Income No Kids) couples. The participants explained why they decided to have or not to have children in the future. They seemed to believe in a traditional family structure and idealize parental roles, while recognizing the high economic and psychological cost of rearing children. They claimed that Korean society set high standards for parents, which were too difficult to reach. The participants, having been educated to believe in self-actualization through their successful careers, struggled to choose between a family with children and one without children. This study was conducted with a holistic view, and highlighted the importance of interactions between traditional ideology about the family and socioeconomic contexts when interpreting college students' perspectives on childless family.

For advanced civil engineering structures a service life of hundred up to hundred fifty and even two hundred years is sometimes required. The prediction of the performance of concrete structures over such a long period requires accurate and reliable predictive models. Most of the presently used, mostly experience based models don't have the quality and reliability that is required for reliable long-term predictions. The models designers are searching for should be based on an accurate description of the relevant degradation mechanisms. The starting point of such models is a realistic description of the microstructure of the concrete. In this presentation the need and the role of fundamental microstructural models for predicting the performance of concrete structures will be presented. An example will be given of a microstructural model with a proven potential for long-term predictions. Besides this also the role of models in general, i.e. in the whole design and execution process of concrete structures, will be dealt with. Finally recent trends in concrete research will be presented, like the research on self-healing cement-bases systems.

Currently, both Korea and Japan have cooperated to get a foothold in economic major countries in the Asia through the various economic cooperation and the overcoming of cultural difference in cultural interchanges between two countries. However, in the present age, two countries are on the other road in historical view and conception; the final report over 3 year studies by the two countries' history study partnership commission shows the above views; while Korea has been in base of Japan colonialization's unjustification, Japan has been in base of its facts. The aboves have proved that Japan has not taken an honest self examination and conscience over the history. Accordingly, Japan resistance volunteer memorial is proposed as the educational place to carry down the martyr's holy patriotism in later ages and practice its spirit by learning the resistance volunteer resistance volunteer movement, which focused on resisting the Japan invasion and fighting the independence.

This paper represents that auto tunings of membership functions and weights in the fuzzy neural networks are effectively performed by immune algorithm. A number of hybrid methods in fuzzy-neural networks are considered in the context of tuning of learning method, a general view is provided that they are the special cases of either the membership functions or the gain modification in the neural networks by genetic algorithms. On the other hand, since the immune network system possesses a self organizing and distributed memory, it is thus adaptive to its external environment and allows a PDP (parallel distributed processing) network to complete patterns against the environmental situation. Also, it can provide optimal solution. Simulation results reveal that immune algorithms are effective approaches to search for optimal or near optimal fuzzy rules and weights.
