Objectives : The aim of this study was to survey the usage frequency of Sasang constitutional herbal formula in the clinlcal field. Methods : We searched the case report forms from 2031 subjects in the 11 oriental hospitals and 10 oriental clinic. Subjects were diagnosed by the Sasang Constitution specialist in oriental hospital, who had remarkable improvement in their chief complain after Sasang Constitution medication. We counted the usage frequency of each constitutional herbal formula. Results and Conclusions : In TE type, Cheongsimnyeonja-tang, Yeoldahanso-tang, Jowiseungcheong-tang, Taeeumjowi-tang were used in high frequency. In SE type, various herbal formula were used in a similar frequency. In SY type, Yanggyeoksanhwa-tang, Hyeongbangjihwang-tang, Dokhwaljihwang-tang were used in high frequency. Additionally, the use of specific herbal formula was concentrated in SY type.

Objectives : The purpose of this study is to extend indications of Four-Constitution Medicinal formulas by comparing with formulas on Dongeuibogam(東醫寶鑑), focusing on their composition. Methods : 1. We analyzed the composition of Four-Constitution Medicine formula which are mentioned on Donguisusebowon(東醫壽世保元), focusing on their composition. 2. We analyzed the composition of formulas on Dongeuibogam(東醫寶鑑) comparing with 24 formulas for So-Eum type, 17 formulas for So-Yang type, 24 formulas for Tae-Eum type, 2 formulas for Tae-Yang type. Results & Conclusions : 1. We finally selected 14 formulas and its effect as similar formulas with Bojungyikgi-tang, Insamjinpi-tang, Cheongunggyeji-tang, Palmulgunja-tang, Hwanggigyejibuja-tang, Hwanggigyeji-tang for So-Eum type. 2. We finally selected 4 formulas and its effect as similar formulas with Dokwaljihwang-tang, Sukjihwanggosam-tang for So-Yang type.

In this paper, we give a representation formula for an isotropic curve with pseudo arc length parameter and define the structure function of such curves. Using the representation formula and the Frenet formula, the isotropic Bertrand curve and k-type isotropic helices are characterized in the 3-dimensional complex space $\mathbb{C}^3$.

In this paper, based on the concept of solid particles' hovering problem the working formula for the channel design of a Decanter-type centrifuge were derived. The Shields' diagram and its curve-fitting formula were used in determining the criterion of particle size for the sediment. By using these formula the designer can determine the sectional configuration of the channel, such as the liquid depth, the normal pitch of the screw-blade arrangement and the bowl diameter.

It is well known that plurigenus does not vanish for a sufficiently large multiple on a canonical threefold over $\mathbb{C}$. There is Reid Fletcher formula for plurigenus. But, unlike in the case of surface of general type, it is not easy to compute plurigenus. In this paper, we in-duce a different version of Reid-Fletcher formula and show that the constant term in the induced formula has periodic properties. Using these properties we have an application to nonvanishing of plurigenus.

The present study investigated the validity of an equilibrium shoreline empirical formula for real phenomena. Among three types of equilibrium shoreline formulas, Hsu's parabolic type static formula was employed, which is well-known and the most practical for shoreline estimation after coastal or harbor structure construction. The wave data observed at Maengbang beach and the CERC formula on longshore sediment transport were used in the present investigation. A comparison study was only conducted for the case of a shoreline change after the construction of a groyne. Reasonable agreement was seen between the observed wave data and the data obtained under a wave angle spreading function S = 3.5. However, significant changes were observed when S increased. Thus, careful application is required when using Hsu's formula.

In robust design, the mean and variance of design performance are frequently used to measure the design performance and its robustness under uncertainties. In this paper, we present the Gauss-type quadrature formula as a rigorous method for mean and variance estimation involving arbitrary input distributions and further extend its use to robust design optimization. One dimensional Gauss-type quadrature formula are constructed from the input probability distributions and utilized in the construction of multidimensional quadrature formula such as the tensor product quadrature (TPQ) formula and the univariate dimension reduction (UDR) method. To improve the efficiency of using it for robust design optimization, a semi-analytic design sensitivity analysis with respect to the statistical moments is proposed. The proposed approach is applied to a simple bench mark problems and robust topology optimization of structures considering various types of uncertainty.

Lee Jema said in his book, Dongui Susebowon, that the prescriptions for Soum constitutional type were already developed by doctors during the Song Jin Yuan China around 10th-13th century. Those prescriptions were common techniques that were used throughout the East Asian region. Among them, Lee Jema specially selected some candidate formulas and modified them according to his constitutional theory. This study investigated how similar his modified prescriptions to original formulas through database[ancient formula database] analysis. 24 out of 24 Soum prescriptions selected meaningful ingredient herbs from the original formula. A 50% or higher concordance rate compared to the original formulas. There are only 9 treatment prescriptions that cannot be checked in the ancient formula database. A future task will be to reveal the practical meanings of the ingredients Lee Jema adjusted for the Soum constitutional type patients.

Two-dimensional laboratory experiments were conducted in a wave flume to investigate the wave transmission phenomena of impermeable-type submerged structures armored by concrete blocks. Different experimental conditions were included by considering relative crest depth, relative freeboard, relative crest width, wave steepness, and so on. An empirical formula was proposed to predict the wave transmission coefficients over various specifications and structural designs of the impermeable submerged structure from the experimental results. The proposed formula successfully predicted the wave transmission coefficients. Therefore, in this study, the proposed empirical formula of the wave transmission over an impermeable submerged structure was improved from the existing formula.

This study presents results of surveys conducted Seoul and Kangreung public health center using structured questionnaire developed by researchers to identify factors that were relevant to the method of feeding. To compare the infant's development between the breast-fed infants and formula-fed infants, infant's height, weight, triceps skinfold during 1month and 4months were cheked. The results were as follows : 1. At postpartum, 59.1% infants had formula feeding, while 22.6% had breast feeding. At 1 month old, 49.6% infants had formula feeding, 27.8% had breast feeding. At 4 months old, 60.9% infants had formula feeding, while 26.1% had breast feeding. 2. 'Lack of breast milk' was the predominant reason for formula feeding. 3. The sujects didn't enough eat not only rice and seaweed soup but also any other specific foods during breast feeding period. 4. Factors that affected the method of feeding were the patterns of delivery, mother's height & weight, first baby feeding type(at post partum), infant sex, mother's age, preparation of breast feeding, first baby feeding type, regular clinic visit (at 4months old). 5. The birth weight and height were correlated with mother's weight and height. 6. There were no significant different on infant's weight, height, triceps skinfold between breast-fed infants and formula-fed infants.
