In this paper, we present an improvement of a closed-form formula for mutual impedance computation. Depending on the center-to-center spacing between two rectangular microstrip patch antennas, the mutual impedance formula is separated into two parts. The formula based on synthetic asymptote and variable separation is utilized for spacings of more than 0.5 ${\lambda}_0$. When the spacing is less than 0.5 ${\lambda}_0$, an approximate formula is proposed to improve the computation for closely spaced elements. Simulation results are compared to computational results of mutual impedances and mutual coupling coefficients as functions of normalized center-to-center spacing in both E- and H-plane coupling configurations. A good agreement between simulation and computation is achieved.

Objectives : Blood stasis (BS) is related to be caused by blood circulation and stagnation which are cancer, atherosclerosis and hyperlipidemia in traditional medicine. We extracted 3 kinds of BS formula; Seogakjihwang-tang (SGT), Tonggyuhawlhyul-tang (THT), Hyulbuchukeo-tang (HCT). This study was conducted to investigate whether the 3 kinds of herbal formula extracts have inhibitory efficacy association with anti-adipogenesis. Methods : To investigate the anti-adipogenesis, we used the mouse fibroblast cell line, 3T3-L1 which differentiated into adipocytes in response to insulin, IBMX and dexamethasone (MDI). Cytotoxicity of herbal formula extracts were examined by CCK-8 kit. Intracellular lipid droplets were detected by Oil-Red-O staining. Triglyceride (TG) and leptin were measure using elisa kit. Results : The yield of water extracts was 14.62% (SGT), 21.27% (THT), 20.02% (HCT). Lipid accumulation was reduced significantly by 3 kinds of herbal formula compared to control. Especially, THT and HCT decreased lipid droplet, respectively at all concentration. The TG and leptin were also inhibited by 3 kinds of herbal formula. The IC50 of TG were $280.51{\mu}g/m{\ell}$ (SGT), $52.62{\mu}g/m{\ell}$ (THT), $313.99{\mu}g/m{\ell}$ (HCT). The IC50 of leptin were $348.76{\mu}g/m{\ell}$ (SGT), $164.02{\mu}g/m{\ell}$ (THT), $257.00{\mu}g/m{\ell}$ (HCT). THT was better than other herbal formula on anti-adipogenesis. Conclusion : kinds of herbal formula inhibited adipogenesis in MDI-induced 3T3-L1 adipocytes, as indicated by the significant reduction in TG and leptin concentration without cytotoxicity. Therefore, 3 kinds of herbal formula for BS might act as a therapeutic agent for preventing lipid diseases, such as obesity and atherosclerosis.

Objectives : This study aims to propose a processing method for dosage units of medicinal materials and the database schema to manage formula data in Korean medicine ontology. Methods : All dosage units of medicinal materials are collected from the seven textbooks that contain formula data of Korea medicine ontology. Dosages are converted to Arabic numerals and units that are frequently used are converted to representative units. Database schema is designed for processing and managing the formulas and medicinal materials with dosage units. Results : Seven representative units are selected out of 77 units. They will be used in the addition or subtraction of medicinal materials in a formula support system. The remaining units will be made available for references. Conclusions : EMR or chart programs used in clinical hospitals contain formula data that is already standardized. However, the formula data in Korean medicine literature and textbook is not refined, so it is necessary to process the dosages and units of medicinal materials to use in the formula support system. This result is a processing method to utilize the formula data of Korean medicine textbooks and it will be implemented this method in the established formula support system in the future.

Effects of medicinal herbs and bee propolis on pork quality were assessed using formulae A (control), B (boiling water extraction with propolis), and C (boiling water extraction without propolis). Seasoning sauce was made with medicinal herb, spices, total flavonoid, and soy sauce with/without 0.4% propolis (21.8 mg/g), mixed with pork, and stored at low temperature $(4{\pm}1^{\circ}C)$ for 20 days. In formula B peroxide value and thiobarbituric acid content increased with increasing storage period. Formula B showed highest Volatile Basic Nitrogen (VBN) and lowest microbial counts, followed by formulae C and A, receiving higher scores for taste and fragrance.

Donguisusebowon(東醫壽世保元) doesn't have pretty large quantity of contents, so indications of Four-Constitution Medicine formulas on that medical book are small. Therefore, indications of Four-Constitution Medicine formula need to be extended for broader clinical use of Four-Constitution Medicine. There would be some methods to do that, and we could review the literatures that Four-Constitution Medicine formulas are based on. We reviewed Bojungyikgi-tang on "Dongeuibogam(東醫寶鑑)", and we found that if the Four-Constitution Medicine formula is based on Sanghan formula(傷寒方) or non-classical formula(後世方), it is worth adding more indications of base formulas to those of Four-Constitution Medicine formula. For exmaple, Indications of Bojungyikgi-tang for So-Eum type could be extended by indications of non-classical formula(後世方) Bojungyikgi-tang and modified formula(加減方) Bojungyikgi-tang on Dongeuibogam, We supposed 23 indications of non-classical formula(後世方) Bojungyikgi-tang, and 20 indications of modified formula(加減方) Bojungyikgi-tang as possible indications of Bojungyikgi-tang for So-Eum type.

Objectives : The objectives of this study is to establish data-base to find out similar herbal formulas with a particular herbal formula by comparing composition ratio of configuring herbs. And this thesis is to analyze differences of prescriptions and find out similar prescriptions by utilizing galenical mass ratio, which is directly related to effectiveness of galenical. Methods : This study was proceeded by using Access 2007 with Window 7(MS) and 2,787 prescriptions of which herbal configuration could be indicated by weight unit were analysed from Donguibogam. We standardize all units of the prescription and input the mass ratio data when entered galenical data. Results : We could confirm a degree of similarity between compared prescriptions and a particular prescription according to the sum of differences of herb weight ratio and similarity ratio. Conclusions : A most similar herbal formula could be searched through comparing multi prescriptions by multi prescriptions of herbal configuration from established herbal formula data-base where herb weight ratio of prescriptions is to be input.

Indications of Hyeongbangpaedok-san for Soyang-type on "Donguisusebowon" are small. Therefore, indications of Hyeongbangpaedok-san for Soyang-type need to be extended for broader clinical use. There would be some methods to do that, and we could review "Dongeuibogam" that Four-Constitution Medicine formulas are based on. We reviewed Hyeongbangpaedok-san, Insampaedok-san which is the origin of Hyeongbangpaedok-san, and their modified formula(加減方) on "Dongeuibogam". As a result, we supposed 12 indications of non-classical formula(後世方) Hyeongbangpaedok-san, 2 indications of modified formula of non-classical formula Hyeongbangpaedok-san, and 12 indications of Insampaedok-san and its modified formula as possible indications of Hyeongbangpaedok for Soyang-type.
