Background : The number of outpatient injected anticancer drug is increasing. and the pathway of prescribing, compounding, and injecting anticancer drug is processed very rapidly in out-patient department. Moreover, Dose of anticancer drug is often changed depending on side effect of patients. So we need more effective inspection of anticancer drug prescriptions. The purpose of this study was to analyze the prescription errors for anticancer drugs in Out-Patient Department and to suggest system to prevent them. Method : The study took place at Asan Medical Center from July to September 2007. The pharmacists performed inspection of anticancer drug prescriptions before compounding and injecting. We used protocol-based anticancer drug order program and Electronic Medical Record (EMR). Result : During the study period, we analyzed 4683 prescriptions for out-patient. And we detected 55 medication errors (1.2%). Most common errors included dosage above or below the correct ones (56.3%), followed by incorrect treatment duration. Because most of dosing errors were in the range of usual dosage, it was hard to detect them. So when inspecting the prescription, we considered the medical records of individual patients. As a result, we could raise the efficiency of intervention. Therefore inspection using EMR could possibly reduce the number of anticancer drug errors. Conclusion : we are preventing the medication errors on stability and dosage above or below the maximum therapeutic dose according to the previous inspection system. However most of dosing errors were in the range of usual dosage according to the result of this study. Because of there was interpatient variability of dosage depending adverse effect. For improvement of quality assurance, we suggest inspection system based on patient's medical history.

The purpose of this study is to examine changes in the pesticides residues in pepper powder by storage conditions. Analysis of pesticide residues was performed using multiresidue analytical methods and the number of pesticides detected from 60 pepper powders was 7 pesticides such as cypermethrin, fenvalerate, kresoxim-methyl, chlorpyrifos, chlorfenapyr azoxystrobin, tebuconazole. The concentrations of cypermethrin and tebuconazole were exceeded their maximum residue limits (MRLs). The degradation patterns of pesticides at $-5^{\circ}C$ were compared to those at $20^{\circ}C$ and $4^{\circ}C$. Without reference to storage temperature, degradation rates of azoxystrobin and fenvalerate were above 80%. Degradation rate of chlorpyrifos was 47% at storage $4^{\circ}C$, $20^{\circ}C$ and 34% at storage $-5^{\circ}C$. During each storage peroid, the degradation patterns were more lower at $-5^{\circ}C$ than at $20^{\circ}C$ and $4^{\circ}C$.

This study presents the optimal isolation period according to the number of vertically expended stories in order to provide the basic data for the application of the seismic isolation system in the vertically expended remodeling of the aged apartment. As a result of the structural analysis, the isolation period should be at least twice the primary structure in three-story vertical expansion, three times in two-story expansion, and four times in one-story expansion for the effective application of the isolation system. On the basis of the result, the efficacy of an isolation system for the actual apartment structure, which is three-story vertically expended, was analytically verified. The maximal acceleration response on the top floor reduced by 70% and 65% of the non-isolated structure in the X and Y directions respectively. Additionally, the base shear force decreased by 30% in the both directions, compared to the non-isolated structure.

When RC structures are repaired or strengthened using FRP, it is required to cure for some Period under certain air temperature and then it is hopeful to avoid detrimental action caused by external vibration sources during that period. Therefore, an effect of repeated loading during Carbon Fiber Sheet(CFS) strengthening Process on the strengthening efficiency is studied through an experiment for a number of RC beams. Experimental results showed that the curing time of 24 hours without any repeated loading after CFS attachment were recommended for 1 ply strengthening, and 12 hours for 2 plies strengthening.

The probabilistic fatigue life analysis is one of the common methods to account the uncertainty of parameters on the structural failure. Frequently, the Bayesian approach has been demonstrated as a proper method to show the uncertainty of parameters. In this work, the application of probabilistic fatigue life prediction method for the aircraft structure was studied. This effort was conducted by using the PoF(Probability of Failure) based on Bayesian approach. Furthermore, numerical example was carried out to confirm the validation of the suggested approach. In conclusion, it was shown that the Bayesian approach can calculate the probabilistic fatigue lives and the quantitative value of PoF effectively for the aircraft structural component. Moreover the calculated probabilistic fatigue lives can be utilized to determine the optimized inspection period of aircraft structures.

Veterinary drugs are widely used to protect production-related diseases and promote the growth of farmed fish. The use of large amounts of veterinary drugs may have potential risk and cause adverse effects on both humans and the environment. In this study, we developed risk-based ranking based on a scoring system to be applied in the national residue program. In this approach, the following three factors of veterinary drugs that may occur as residues in fishery products were considered: potency (acceptable daily intake), usage (number of dose and withdrawal period), and residue occurrence. The overall ranking score was calculated using the following equation: potency × usage (sum of the number of sales and withdrawal period) × residue occurrence. The veterinary drugs that were assigned high score by applying this approach were enrofloxacin, amoxicillin, oxolinic acid, erythromycin, and trimethoprim. The risk-based approach for monitoring veterinary drugs can provide a reliable inspection priority in fishery products. The developed ranking system can be applied in web-based systems and residuemonitoring programs and to ensure safe management of fishery products in Korea.

After constructing the high-speed railroad, KORAIL acquired advanced maintenance techniques about Rolling-stocks. Also RCM theory is applied to maintenance field like as inspection period and method. In the meantime, the development of the maintenance methode for Rolling-stock is slow when it compares to the components and system technology. For this reason KORAIL tries to build the optimal maintenance system which can lead the Rolling-stock maintenance technique. The existing vehicle except High Speed train KTX are separated to electric motor car, electric locomotive, diesel locomotive, diesel car, passenger car and freight car. The inspection period and methode for existing vehicles which mentioned above will be examined and the optimal Rolling-stock maintenance technique will be applied.

For more districted seismic design and attemped multi-bridge continuity, the existing seismic design is difficulted to treat seismic activity. So, many company applied multi-fixed point and damper or isolator, which is effective for decreasing seismic energy, on period shift, decentralization and damping. But, there is hard to design special bridge with adjusted seismic system because of absence seismic device and insufficient design experience. Therefore, the study on behavior characteristics of designed bridge with various seismic device is performed to utilize the result of this for selection of adequate seismic device.

This study is for quality standard establishment of urethane waterproofing membrane method which is mostly applied to waterproofing method for underground parking lot and rooftop. The experiments were carried out on color differences, membrane thickness, tensile property by curing period of liquid urethane before placing protective concrete, and resistance of crack movement according to different substrate surface and reinforcement of non-woven fabric. As a result of experiments, it was found that color differences is increase, membrane thickness is thick, tensile property is low as concrete placing period is shorter. In the fatigue property, membrane thickness of 3 mm was not broken, but 1~2 mm was broken and in the case of the membrane reinforced with non-woven fabric was more stable comparatively non-reinforcement one.
