Objectives: The goal of this project was to measure the antibacterial effectiveness of Hwangryunhaedok-tang (barberry root decoction for detoxification) and its constituents. All of the active ingredients including the final product were prepared using high-pressure sterilization for use as medicinal eye drops. The varying forms of Hwangryunhaedok-tang (barberry root decoction for detoxification) were used to treat Staphylococcus epidermidis and Enterococcus faecalis which are found in keratitis. Methods: The antibacterial effect was measured by observing the presence or absence of antimicrobial activity when treated with varying concentrations of Hwangryunhaedok-tang extract. The tests were performed using a dosage of $70{\mu}l$ dosages of 100%, 50%, 10% and 1% the extracted solution by the minimum growth inhibitory concentration measurement. Antimicrobial activity was measured by examining the correlation between dosage strength and bacterial activity from $70{\mu}l$ to $10{\mu}l$ at the same concentration. Results: 1. Hwangryunhaedok-tang (barberry root decoction for detoxification), Phellodendri Cortex, and gardenia didn't show any antimicrobial effects against S. aureus, S. epidermidis, or E. faecalis. 2. Barberry root showed antimicrobial effects against S. aureus and S. epidermidis depending on the levels of concentration but didn't show any antimicrobial effects against E. faecalis. 3. Skullcap showed antimicrobial effects against S. aureus and S. epidermidis when a dosage of 100% extract $70{\mu}l$ was used. However, did not show any antimicrobial effects at all against E. faecalis. Conclusions: Hwangryunhaedok-tang (barberry root decoction for detoxification) and its constituents such as barberry root, phellodendri cortex, skullcap, and gardenia, can be used as an alternative to antibiotic medicinal eye drops to treat keratitis. However, further research on effective uses of and efficient extraction methods are needed.

IMT-2000망 핵심기술은 mobile IP를 이용하는 북미의 3G packet data system과 GSM망과 연계를 하는 유럽의 GPRS로 구분할 수 있다. 이러한 IMT-2000망 핵심기술은 글로벌한 로밍을 위해 Mobile IP도입을 추진하고 있다. Mobile IP상에서는 RADIUS나 DIAMETER같은 AAA 서버가 다이얼 업 컴퓨터의 인증, 허가 서비스를 제공하기 위해 사용되고 있는데, 이것은 MN에게 매우 중요하다. Mobile IP는 MN과 HA간에 강력한 인증을 요구하기 때문이다. 본 논문에서는 이러한 IMT-2000 환경에서 고려되고 있는 Smooth Handoff 기법에서 효과적인 AAA프로토콜의 적용에 관하여 논한다. IMT-2000 technologies are divided 3G packet data system that using mobile IP and GPRS that based on the GSM networks. These technologies Push introduce mobile IP to support seamless roaming. In mobile If environments, use AAA server such as RADIUS or DIAMETER to provide authentication service for dial-up computers. This factor is important for mobile nodes. Mobile If require strong authentication between mobile nodes and home agents. We propose application of AAA protocols for smooth handoff mechanism in IMT-2000 environments.

Objectives: This study was conducted to investigate the actual condition of the farm work environment and personal protective equipment as part of the effort to improve livestock work for the safety and health of poultry farmers and provide basic data for establishing plans to improve and develop personal protective equipment. Methods: For this purpose, a questionnaire survey on general information about stables, the poultry work environment, accidents, the wearing of work clothes and personal protective equipment, and the level of awareness related to personal protective equipment was conducted among 148 poultry farmers. Results: As a result, it was found that poultry workplace environment was exposed to such risks as fine dusts; organic dusts; poisonous gases; odorous substances; chicken excrement; contact with chickens, bacteria or viruses; and accidents related to machine operation. Thirteen percent of respondents suffered severe respiratory diseases, and the most frequently injured sites due to accidents were the hands (25.7%), knees (23.8%), arms (17.3%), and head (10.9%). The most frequent type of accident was collisions between the body and obstacles or machinery during movement (36.4%), followed by erroneous machine operation such as feeders and electric shocks (8.5%). Regarding the wearing of work clothes and personal protective equipment, 51.7% of the respondents wore worn-out clothing or everyday clothes, whereas only 32.0% wore work clothes. The percentage of farmers who wore proper protective equipment for the work environment during poultry work was 48.4%. The most frequently used type of protective equipment was boots (38.9%), followed by mask (36.7%), gloves (36.3%), appropriate work clothes (22.6%), quarantine clothes (17.6%), helmets (13.4%), and goggles (12.6%). The rate of wearing goggles was low because they were considered inconvenient and lowered work efficiency. Furthermore, they purchased everyday products available on the market for their personal protective equipment which were not appropriate for maintaining safety in an actual harmful environment and its consequent risks. As a result of the survey of the awareness level related to personal protective equipment, their levels of awareness of accidents and attitude proved to be average or higher, but the practice of wearing protective equipment and the level of knowledge and management of personal protective equipment were lower. Conclusion: This survey found that the wearing status of personal protective equipment among poultry farmers was insufficient even though they were exposed to risks. Most respondents were aware of the necessity of wearing personal protective equipment and of the potential for accidents, but they did not wear proper protective equipment. Their wearing rate was low due to a lack of knowledge about protective equipment, as well as the inconvenience of wearing it. Therefore there is a need to improve and develop specialized personal protective equipment for respiration, hands, and eyes, as well as work clothes that can protect farmers from major harmful matter that is generated in the poultry workplace. Based on the results of this investigation, we will conduct further studies on the required performance and design directions of personal protective equipment while collecting more objective data through field-oriented assessments.

Nutrient removal in the effluent of manufacturing company is considered to be the major control parameter to prevent and reduce the risk of eutrophication and red tide problems occurring in lakes, reservoir, and coastal area. Twenty eight companies out of three industrial complex(Chungju, Yeochon, Iksan) producing more than 60㎎/L of total nitrogen(T-N) in the effluent were selected for detailed study. Existing treatment processes, concentrations of wastewater, and flowrate were throughly investigated. Mean values of T-N concentration from Chungju, Yeochon, and Iksan industrial complex were 297, 204, 1,613㎎/L, respectively. However, those concentrations were mostly influenced by one or few companies discharging significantly high nitrogen effluent Optimum treatment processes were proposed to bring the effluent nitrogen concentration below the regulated level using market-available technologies.

In this paper, we study on the identification of discrete-time state-space model for robust control of tandem cold mill, using a MOESP(MIMO output-error state-space model identification) algorithm based on subspace method. It is shown that the identified model is well adapted to input-output data sets, which are obtained from nonlinear mathematical equations of tandem cold mill. Furthermore, deterministic H$\infty$ norm bounds on uncertainties including modeling errors and disturbances are quantitatively identified in the frequency domain. Finally, the results give a basic idea to determine weighting functions included in formulating some robust control problems of tandem cold mill.

The nature of hydrophobic sites on the protein surfaces of the Pr and Pfr forms of phytochrome (118 kDa) has been studied by spectroscopic and electrophoretic properties of phytochrome that was partially digested with α -chymotrypsin. The enzyme digestion bleached the Pfr spectrum completely at a 1:60 (w/v) enzyme to substrate ratio, while the Pr absorbance was decreased by 20%. SDS-gel electrophoresis of the α -chymotrypsin-digested phytochrome showed that, at an early stage of digestion, the rate of hydrolysis was faster in the Pr form and the electrophoretic pattern of polypeptide digests was more complicated in the Pfr form than in the Pr form. The chromopeptide domain was more resistant to α -chymotrypsin digestion than the nonchromophore domain. The pronounced susceptibility of the Pfr spectrum to α -chymotrypsin was considered to be the action of the enzyme on hydrophobic site(s) at the chromophore vicinity that was newly developed by phototransformation from the Pr form to the Pfr form.
