The purpose of this case series was to investigate the effectiveness of Bojungikki-tang-gamibang for vascular dementia. The case subjects were nine patients who were diagnosed as vascular dementia by Mini-Mental State Examination-Korean (MMSE-K) and Hachinski's ischemic score. They were inpatients at the Kumi Oriental Medical Hospitalof Daegu Haany University from February in 2008 to Aprile in 2009. They were treated with Bojungikki-tang-gamibang. Results of before and after therapy were evaluated and scored using Korean-version Dementia Rating Scale (K-DRS). The results were analyzed using statistical methods, such as Wilcoxon signed rank test and Mann-Whitney U test. The study showed that the K-DRS score significantly increased after treatment (P<0.05). In summary, this cases report suggests that Bojungikki-tang-gamibang appears to be effective in the treatment of vascular dementia.

Polyurethane diagnostic membranes were prepared to measure blood glucose level of diagnostics. Final absorbances at 680 nm through activated polyurethane membranes were measured at various concentration of glucose in blood. The end-point results of varing absorbance values as time (K/S) was found to have a linear relationship toward the blood glucose concentration. The effects of hematocrit on the glucose concentration measurements were examined. In low hematocrit, dose-response slope (DRS) values between gluose concentration and K/S values did not show the big differences compared to those in plasma. However, in high hematocrit (more than 40%) DRS values were considerably decreased.

A new type of diagnostic membranes based on methoxyethoxy and trifluoroethoxy co-substituted polyphosphazene has been prepared to measure blood glucose level of diabetics. Final absorbances at 680 nm through activated polyphosphazene membranes were measured at various concentration of glucose in plasma or blood. The end-point results of varing absorbance values as time (K/S) was found to have a linear relationship toward the blood glucose concentration. The effects of substitution rates with hydrophilic groups and hydrophobic groups on the measurements of glucose concentration were studied. Dose-response slope (DRS) values between glucose concentration and K/S values increased as the hydrophilic substitution rates increased. However, in more than 30% of the substitution rates, it was difficult to measure exact concentration level of glucose because DRS increased rapidly.

A new site classification system and site coefficients based on local site conditions in Korea were developed and implemented as a part of minimum design load requirements for general seismic design. The new site classification system adopted bedrock depth and average shear wave velocity of soil above the bedrock as parameters for site classification. These code provisions were passed through a public hearing process before it was enacted. The public hearing process recommended to modify the naming of site classes and adjust the amplification factors so that the level of short-period amplification is suitable for economical seismic design. In this paper, the new code provisions were assessed using dynamic centrifuge tests and by comparing the design response spectra (DRS) with records from 2016 Gyeongju earthquake, the largest earthquake in history of instrumental seismic observation in Korea. The dynamic centrifuge tests were performed to simulate the representative Korean site conditions, such as shallow depth to bedrock and short-period amplification characteristics, and the results corroborated with the new DRS. The Gyeongju earthquake records also showed good agreement with the DRS. In summary, the new code provisions are reliable for representing the site amplification characteristic of shallow bedrock condition in Korea.

Cationic rosin sizes are prepared by premixing extremely pure ployaluminum chloride (PAC) and dispersed rosin size (DRS). It turned out that zeta potential and particle size of the sizing agents took a big change by Plus90 analyzer's and FTIR analyzer's analysis. It turned out that -C=O and -COOH of the DRS have both chemical reaction with PAC to form the muti-hydroxyl aluminum rosin acid and that the cationic rosin sizes modified by PAC has dissymmetric and symmetric flexible vibration two absorbing peaks of the groups (its absorbing peaks $at1596cm^{-1}\;and\;1425cm^{-1}$). By DRS reacting with PAC, zeta potential of the resin size varied from negative to cationic. $Al_{2}O_{3}/rosin=1:0.3$, zeta potential of premixed admixture is tiptop28.8mv, When joined continuously PAC, zeta potential of cationic rosin sizes descend on the contrary.

Dementia is a syndrome charaterized by a decline in multiple fields of cognitive domains. This is the case of a vascular dementia patient with disorientation, memory impairment and mental disorders. The patient was treated with herb medicine, Sesimtang mixed Gujuntang. As a result of herb medication, patient’s memory and disorientation were improved and the score of K-DRS(Korea-Dementia Rating Scale) and MMSE-K(Mini-Mental State Examination-K) was ascended.

The purpose of this study was to investigate the clinical application of oriental medical therapy to Pick's disease We treated the patient with oriental medical therapy. The recovery of the dementia was evaluated by Korean-Mini Mental State Examination(MMSE-K), Korean-dementia Rating Scale(K-DRS) & Barthel ADL Index.(ADL) The applicability of oriental medical therapy has positive effects on the patient with Pick's disease. The Sum of MMSE-K score was increased. K-DRS & ADL were also promoted.

The real-time dynamic rating system(DRS) can provide the maximum ampacity within required periods, so it can help the transmission-line operation more safely and efficiently. Because the conductor temperature is the main limit of increasing rating current, conductor temperature monitoring(CTM) technology is the basic to DRS. In this paper, real-time CTM was developed for 345kV XLPE cable in tunnel and we have also compared the CTM result of this study with the result according to IEC 287 and JCS 168 thermal parameters.

Multilateration acquires the transponder signal of target from receivers installed on the ground and calculates the position of the target using the difference of the signal acquisition time of each receiver. One of the factors that influence the positioning accuracy of Multilateration using the TDOA calculation method is the error due to the precision measurement of signal input time. When measuring the signal input time at the receiver, the input signal is sampled using the reference clock of the receiver and a reference sample having the same sampling rate is applied to the cross correlation technique. Therefore, the accuracy of the signal input time is proportional to the reference clock. In this paper, the algorithm for precisely measuring the signal input time by performing cross correlation between the input signal of the receiver and DRS(Delayed Reference Sample) is proposed. In order to verify this, we implemented the pulse signal of the transponder that is transmitted from the target using Matlab. Through the simulation, cross correlation between the proposed DRS and the input signal was performed. From this result, the performance of the precise measurement of signal input time was analyzed.

In case of inspection on aluminum castings, traditional RT (Radiographic Testing) method have been utilized for its advantages in interpretation, cost and perpetual storage. But it has disadvantages like time consumption in film processing, low efficiency in storage and environmental pollution. In this thesis, a DRS (Digital Radiography System) utilizing X-Ray TDI Camera (Time Delay and Integration Camera) is developed. Inspections on aluminum castings are performed using the developed Digital Radiography System, DRS and reviewed if newly developed system can substitute for the traditional method.
