Objectives This experimental study was performed to investigate the continuous anti-bacterial potency of Coptidis rhizoma extract on cultivation of Staphylococcus species(S. aureus, S. epidermidis) that induce eye disease. Methods Minimal inhibitory concentration(MIC) was measured by dropping to $50{\mu}l$ diluted Coptidis rhizoma extract(100%, 10%, 1%, 0.1%) on S. aureus, S. epidermidis that were cultivated from 2 to 6 days. Anti-bacterial potency was measured by the size of inhibition zone with change of volume($20{\mu}l,\;30{\mu}l,\;40{\mu}l,\;50{\mu}l$). Results 1. Anti-bacterial potency of Coptidis rhizoma extract on S. aureus was appeared in 100%, 10% and was the same as anti-bacterial potency of 2 days and 6 days. Anti-bacterial potency with change of volume(100%) was increased in propotion to increase volume on all samples. Anti-bacterial potency with change of volume(10%) was increased in propotion to increase volume on all samples except $20{\mu}l$. Anti-bacterial potency of Coptidis rhizoma extract on S. aureus was appeared continuous. 2. Anti-bacterial potency of Coptidis rhizoma extract on S. epidermidis was appeared in 100%, 10% and was the same as anti-bacterial potency of 2 days and 6 days. Anti-bacterial potency with change of volume(100%) was increased in propotion to increase volume on all samples. Anti-bacterial potency with change of volume(10%) was appeared in $50{\mu}l$. Anti-bacterial potency of Coptidis rhizoma extract on S. epidermidis was appeared continuous. Conclusions Anti-bacterial potency of Coptidis rhizoma extract on cultivation of S. aureus & S. epidermidis was showed continuous.

An air in the atmosphere is acting constantly without letup. In the air contains not only various kinds of harmful and harmless elements but also always water vapor. In propotion to temperature this vapor transforms atmospheric phenomena. Let's use the air in accordance with various uses in reasonable regulation.

In large construction site, although soil conversion factor is so significant to preliminary design, operation design and calculating the cost of construction that it is important to take reasonable estimation and application, the standard of soil conversion factor for weathered ground doesn't clearly suggested yet. So in this study, at first we obtain the image using DSLR - high resolution camera and Laser scanner in the Haeng-Bok city constructin site, then analysis the ratio of soil and rock using various image processing method(Sobel method, Laplace method, Highpass filter, Hue and Saturation analysis). Mutual comparation with the result of image processing analysis and manual segmentation of 5case image in the cad. As a result, best image processing method was different for each case. In case of high propotion of rock, Laplace was best and in case of high propotion of soil, Highpass was best, and mixed case Laplace was best.

The study aimed to perform the qualitative analysis of food and nutrition informations offered in TV program by monitoring newscastings, health-related programs giving food and nutrition information, dramas for family, education programs for children, and information programs for elderly in major TV broadcasting station(KBS, MBC, SBS, EBS). In this study, statistical analysis were done for numbers of information items related to health or food and nutrition informations. Duration of program the main, subject, sources, evaluation criteria of the contents. Results of qualitative monitoring for TV program are as follows. For health-related informations major propotions of subjects for the newscastings were about diseases. Those for health information programs were about foods. Those for children-education programs were about groceries. Those for seniors’ information programs were about eating habits. The analysis of food and nutrition information sources for most of programs were interviews with specialist and normal person, and on-the-spot-investingations. For food and nutrition informations those were evaluated as inappropriate, the propotion of news was increased to 72.2% in 2003 from 49.3% in 2002. For health information programs, it was increased to 67.7% in 2003 from 54.0% in 2002. But, in drama the propotion of inappropriate scenes were decreased to 16.2% in 2003 from 63.2% in 2002. In children-education programs, it was 40.0%. In seniors’ information programs, it was 17.9% in 2002. The propotion of cases that the quantity of foods is inappropriate in the food scene of serial drama, decreased to 15.8% in 2003 from 28.6% in 2002. The rate of drinking scenes increased to 11.5% from 10.7%. The rate of smoking scenes decreased to 0.2% from 1.6% due to the broadcasting self-regulation of smoking scenes in dramas. In the newscatings and information programs, reasons of being evaluated as inappropriate was that they didn’t have any practical suggestions and proper intakes. There were also insufficient explanation for technical terminology, different comparison standard of nutritive value, and exaggeration for physiological effect of food. The drama contained a lot of unnecessary scenes of alcohol drinking, coffee drinking, midnight meal, and had more quantity of foods than the quantity needed for persons to the scene. As the result of this study, the rate of food and nutrition information were high, but the rate of information which was evaluate as appropriate was not sufficient. There are need to improve contents of information and to moniter the contents for consumer.

In this paper, a instantaneous speed measurement method using a three phase sinusoidal encoder is described and it's simulations are developed. The proposed method can easily detect the AC motor speed by using that the encoder is propotion to the AC motor speed. The performance of proposed method is confirmed by computer simulation and experiment results. The high accuracy of the optimum control system, AC motor speed detection is designed and proposed.

In this paper, a instantaneous speed measurement methode using a three phase sinusoidal taco-generator is described and it's simulations are developed. The proposed methode can easily detect the motor speed by using that the output voltage of taco-generator is propotion to the motor speed. Because the proposed methode consists of some calculation, the proposed system can be implemented with analog devices or micro processor conveniently. From the simulation resualts, the proposed measurement methode can acculately detect the real motor speed over wide range.

추잠기의 적엽정도가 지조의 수량에 미치는 영향을 알기 위하여 시험을 한 바 다음과 같은 결과를 얻었다. (1) 추기에 있어서의 적엽의 영향은 조장이나 조률과 같은 형태적인 면보다는 조량과 같은 질적인 면에 더 크게 나타나고 있다. 2. 조량은 중간부적엽구를 제외하고는 추잠기의 적엽량과 반비례하여 무적엽구, 불반부적엽구, 중간부적엽구가 크고 상반부적엽구와 전적엽구는 작았는데 중간부적엽구는 추기의 적엽량이 많았는데도 조량이 컸다. (3) 춘잠기의 수량은 조량과 정비례의 관계에 있어 조량이 큰 무적엽구, 중간부적엽구, 하반부적엽구의 순위대로 많았고, 상반부적엽구, 전적엽구의 순으로 적었다. (4) 연간합계수량은 중간부적엽구가 가장 많아서 무적엽구에 비한다면 36％, 가행법인 전적엽구(상단 5잎 남기고)보다는 13％정도 많았다.

Objectives : This experimental study was performed to investigate the continuous anti-bacterial potency of Tangpo-san on cultivation of Staphylococcus species(S. aureus, S. epidermidis)that induce eye disease. Methods : Minimal inhibitory concentration(MIC) was measured by dropping to 50 ${\mu}$l diluted Tangpo-san(100%, 10%, 1%, 0.1%) on S. aureus, S. epidermidis that were cultivated from 2 to 6 days. Anti-bacterial potency was measured by the size of inhibition zone with change of volume(20 ${\mu}$l,30 ${\mu}$l,40 ${\mu}$l,50 ${\mu}$l). Results : 1. Anti-bacterial potency of Tanpo-san on S. aureus was not appeared all samples. Anti-bacterial potency with change of volume was increased in propotion to increase volume, and the Anti-bacterial potency of 2 days was equal to 6 days. Anti-bacterial potency of Tangpo-san on S. aureus was appeared continuous. 2. Anti-bacterial potency of Tangpo-san on S. epidermidis was appeared in 100%, 10% on 2 and 6 days, and the Anti-bacterial potency of 6 days was decreased. In 2 days, Anti-bacterial potency was appeared 40 and 50u1, in 6 days, Anti-bacterial potency was appeared all samples. Anti-bacterial potency with change of volume was increased in propotion to increase volume and increased on 6 days, but bacteria was increased. Anti-bacterial potency of Tangpo-san on S. epidermidis wasn't appeared continuous. Conclusions : Anti-bacterial potency of Tangpo-san on cultivation of S. aureus showed continuous, but on cultivation of S. epidermidis was not showed continuous.
