A 2-site immunoradiometric assay for serum ferritin was evaluated with commercially available kit. The assay required 6 hours. The slope of the standard curve kept up ideal range with the calculation of maxium binding instead of total dose until expire date. The stage II washing was more important than the stage I washing on the modified washing procedure as the bead keeping to remain in the tube. With this modified mothod, three times of tube. washing was sufficient to reduce the significant errors The measured values of serially diluted sample with standard diluting buffer was proportional to the predicted values. In the experiment of serum effect on the assay. a linear relationship from 5 to 50% serum, but beyond 50% there was reduction in measured ferritin concentration. It has a sensitivity of 2.77 ng/ml, within-assay precision (CV) of 8.0%, and between-assay reproducibility(CV) of 7.4% (mean 174.8 ng/ml).

Objectives : Boo-ja and Cheon-o are not commonly prescribed, but are necessary for some clinical conditions, dispite the fact that some negative effects have been known to occur with these medicines. Hence, consequences for aspartate aminotransferase(AST), alanine aminotransferase(ALT) due to herbal medicines, including boo-ja and cheon-o are here reported. Methods : From January 2005 to July 2005, results were analyzed for 36 inpatients belonging to the sixth internal medicine department of Dongeui Oriental Medical Hospital who took herbal medicine, including boo-ja and cheon-o, over 20 days. The study is about the comparison and the investigation of LFT, and all results were taken upon their hospitalization and upon their departure. The standard of liver injury was used as a standard for their examinations. Results were as follows : No Change in normal limit : 28 of the 36 Increased AST. ALT from when they were hospitalized : 2 of 36 Normalized AST. ALT from when they were hospitalized with results higher than normal : 6 of 36 These results show no side-effects, therefore suggest that these herbal medicines, including boo-ja and cheon-o, do not cause adverse side-effects for patients of this kind if administered as was done in this study.

Objective : The purpose of this clinical study was to investigate the effects of moxibustion on functional recovery in stroke patients. Methods : Forty two stroke patients were randomized into either the standard physiotherapy treatment combined with moxibustion group or a control group with standard physiotherapy alone. They were 8 weeks from onset to the start of this study. Moxibustion was applied at 合谷(LI14), 外關(TE5), 曲池(LI11), 太衝(LIV3), 懸鍾(絶骨,G39), 足三里(S36) in hemiplegic upper and lower extremity, once a day for 6 weeks. The effect of treatment on functional recovery was assessed using the Functional Independence Measure scale. Statistical significance was achieved if the probability was less than 5%(p<0.05). Result : These 2 groups had comparable clinical characteristics; sex, age, lesion, and pre-treatment FIM score. After 6 weeks, patients in the moxibustion group performed better on FIM. The differences were significant(P=0.001). Conclusion : These results suggest that moxibustion is an effective treatment for functional recovery in stroke patients.

In order to protect personal information and important information (confidential information, sales information, user information, etc.) in the internal network, companies and organizations apply encryption to the Server-To-Server or Server-To-Client communication section, And are experiencing difficulties due to the increasing number of known attacks and intelligent security attacks. In order to apply the existing S / W encryption technology, it is necessary to modify the application. In the financial sector, "Comprehensive Measures to Prevent the Recurrence of Personal Information Leakage in the Domestic Financial Sector" has been issued, and standard guidelines for financial computing security have been laid out, and it is required to expand the whole area of encryption to the internal network. In addition, even in environments such as U-Health and Smart Grid, which are based on the Internet of Things (IoT) environment, which is increasingly used, security requirements for each collection gateway and secure transmission of the transmitted and received data The requirements of the secure channel for the use of the standard are specified in the standard. Therefore, in this paper, we propose a secure encryption algorithm through mutual authentication and grouping for each node through H / W based Network Control Server (NCS) applicable to internal system and IoT environment provided by enterprises and organizations. We propose a protocol design that can set the channel.

To develop the Korean standard differentiation of the symptoms and signs for the stroke(KSDS), the committee on Stroke Diagnosis Standardization of traditional Korean medicine(TKM) was organized dy nineteen experts in college of Korean medicine. On July 9th 2005, the second consultation meeting was held in Daejeon, Korea. Fifteen experts of the committee attended the meeting and they discussed the KSDS and came to a consensus. The 15-member committee consensus was as follows: First, board members defined the stroke on the basis of TKM. Second, they divided the symptoms and signs of stroke into five categories- fire and heat, dampness and phlegm, blood stasis, qi deficiency, yin deficiency. Third, the symptom indicator of each differentiation type for the stroke was recommended. KSDS-1 will be applied to the clinical practice and revised.

This study was performed to determine the characteristics of physical and mechanical properties of domestic wood based materials; plywood, particleboard, medium density fiberboard. Main items of tested properties were panel size, moisture content, water absorption, linear expansion and thickness swelling, glue bond shear strength, bending properties(stress at proportional limit, modulus of rupture. modulus of elasticity), tensile strength, screw holding strength, and internal bond as neccessary. the results were discussed mainly with Korean Standards. The obtained conclusions are as follows; 1. Length and width of 3mm thin plywood(3-ply) and 12mm thick plywood(7-ply) were satished with KS-standard, but thicknesses of these panels were not- passed tolerance limit except one of eight makers. 2. Length and width of particleboard and medium density fiberboard were greater than the tolerance limit value of KS standard, but the thicknesses of these panels were passed this value. 3. Moisture contents of 12mm thick and 3mm thin plywood were satisfied with KS-standard except one mill made 3mm thin plywood. 4. Moisture absortion of plywood was not passed tolerance limit of KS-standard but particleboard was satisfied with this standard value. 5. Dry and wet shear strengths in glue bond of 3mm thin plywood were not reached to KS-standard, but those of 12mm thick plywood were sufficiently satisfied with KS standrad. 6. Modulus of ruptures, parallel to grain and perpendicular to grain of plywood, and particleboard and medium density fiberboard were satisfied with KS-standard. 7. Tensile strengths, parallel to grain and perpendicular to grain of plywood were satisfied with allowance stress of US product standard PS 1-74. 8. Screw holding strength of particleboard was not reached to KS standard, but internal bond was satisfied with KS standard.

The internal standard method using ion chromatography combined with tandem mass spectrometry (IC-MS/MS) for quantifying perchlorate in different types of food was established. Because the presence of ions and other biomolecules in matrices usually interrupts accurate determination of perchlorate, it is necessary to develop efficient, reproducible method to determine perchlorate concentrations in food. In this study, the internal standard method was compared with the external standard method to determine perchlorate concentrations in standard samples. The obtained method detection limit (MDL) for perchlorate was 0.005 ${\mu}g/L$ for bottled water, 0.12 ${\mu}g/L$ for milk, 0.27 ${\mu}g/kg$ for rice, 0.16 ${\mu}g/kg$ for vegetables, and 0.07 ${\mu}g/kg$ for seaweed, respectively. The limit of quantitation (LOQ) was calculated by multiplying the MDL by 7. The recoveries of perchlorate from food samples spiked with perchlorate ranged from 98 to 105% and their percent relative standard deviation (%RSD) levels were <20%. This method was successfully applied for the quantitative determination of perchlorate in various kinds of food.

Current 'Pronunciation Methods of Standard Korean(PMSK)' has several problems. Some of those are from conflicts with linguistic reality, and the rest are from their internal inconsistencies. So, we feel that it should be revised as soon as possible. But it seems that the revision is not the best way, because linguistic change will make us revise it continually. The only way to establish its reasonable alternative is that we should update our descriptive dictionary whenever we need to.

Reproducing the horizontally homogeneous atmospheric boundary layer in computational wind engineering is essential for predicting the wind loads on structures. One of the important issues is to use fully developed inflow conditions, which will lead to the consistence problem between inflow condition and internal roughness. Thus, by analyzing the previous results of computational fluid dynamic modeling turbulent horizontally homogeneous atmospheric boundary layer, we modify the past hypotheses, detailly derive a new type of inflow condition for standard k-ε turbulence model. A group of remedial approaches including formulation for wall shear stress and fixing the values of turbulent kinetic energy and turbulent dissipation rate in first wall adjacent layer cells, are also derived to realize the consistence of inflow condition and internal roughness. By combing the approaches with four different sets of inflow conditions, the well-maintained atmospheric boundary layer flow verifies the feasibility and capability of the proposed inflow conditions and remedial approaches.
