In the semiconductor equipment industry, the SECS/GEM protocol has been recognized as the communication standard, but in our 300mm wafer aligner being developed, this capability has not been equipped yet. In this study, we present the realization of SECS-I, SECS-II and HSMS communication protocol between factory host computer and wafer aligner. Its validity is shown in actual test environment.

For the estimation and test of long memory feature in volatilities of stock indices and individual companies semiparametric approach, Geweke and Porter-Hudak (1983), is employed. Empirical study supports the strong evidence of volatility persistence in Korean stock market. Most of indices and individual companies have the feature of long term dependence of volatility. Hence the short memory models are unable to explain the volatilities in Korean stock market.

"Samsung Composite Shear Wall System" has its basis on "Samung Able System". "Samsung Able System" has some problems not only in the connection structure but also in waterproofing and soundproofing. We developed "Samsung Composite Shear Wall System" in order to solve these matters and expand PC system. "Samsung Composite Shear Wall System" is the compromise and complement of all the merits of full PC, half PC and in-situ concrete system.

In regression model with nested error structure interval estimations on regression coefficients in different stages are proposed. Ordinary least square estimators and generalized least square estimators of the regression coefficients in this model are derived for between and within group model. The confidence intervals are dervied by using independent idstributional properties between regression coefficient estimators and quadratic froms obtained from the model.

This paper presents a valuation methodology for optional calling plan contracts on free-phone calls in the telephone industry. Utilization of the model is not limited to valuation and consequent decision making for the subscribers; it provides a useful guideline for telephone companies in designing calling plans and assessing subscribers' behavior.

This study was investigated the effects of ultrasound for collagen fiber in open wounded of skin. Each group was treated under the following conditions; group I was applied 1MHz continue wave US. group II was applied 1 MHz pulse wave, group III was applied control group. The results were prominent in observation of scar tissue of group II.

The domestic animals in Korea, Especially Korean native cattle, are suffering from eurytremiasis. For instance, the cattle in Korea show much higher infection rates of Eurytrema spp. than the cattle in any other countries. They vary from 50 to $80\%$

The moving average filter in this paper, which has robust performance to the noise and can be easily implementable in hardware, is modified in view of real-time processing of the focus value. The simple hardware configurations are implemented to calculate the focus value in real-time. The stable controller of focus lens actuated by motors are designed. The hardware which are composed of EPLD, cheap vision chips, and CPU etc. are designed to perform the real-time calculation of focus value.

Hot spring water is petrifaction water and mixed with animals and plants disintegrated water in the underground. The ingredient are complicated and abundant. The contained element is used to facilitate the function of human body. activate the human structure movement. discharge waste material due to increase circulation and metabolism, also it can remain the homeostasis. We can not find research for spa therapy in our country. We use to drink and bath in the hot spring water bue don't have rehabilitation facilities

We measured small optical beam deflection in an image rotating Sagnac interferometer. We used a weak value measurement scheme that involves a pre-selection, weak perturbation, and a post-selection procedure to obtain the amplified value of beam deflection. The amplification factor of the measured beam deflection varied from 11 to 63 depending on the settings of the post-selection polarizer in front of the photodetector and the settings of polarization compensator in the interferometer.
