This thesis mainly deals with how 'count of Ryang' was used in Joseon dynasty. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in Joseon dynasty does not differ from now one. But the usages of that are slightly different to the present day. In Joseon dynasty, count of Ryang mainly was appeared with another word, count of Kan. Count of Kan has two meanings. One is the length, and the other is the area of building. When they used the count of Ryang combined with Kan, count of Kan had the meaning of length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. In the 19th century, count of Ryang looks similar to the past, but count of Kan shows another aspect. It did not indicate the length but the area of building. Through this study, although the usages of Ryang were different to the present, the concepts of Ryang were similar in Joseon dynasty.

This thesis mainly deals with how 'count of Ryang' was used in the Daehan Empire. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in the Daehan Empire does not differ from now one. But the usages of that are different from the Joseon Dynasty, and from the present. In the Daehan Empire, count of Ryang mainly was appeared with another word, count of Kan. In the Joseon Dynasty, they used the count of Ryang combined with Kan. Count of Kan had the meaning of purlin-directional length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. But in the Daehan Empire, count of Kan, especially the beam-directional length was considered at first, and then count of Ryang. Separately they used another count of Kan meaning the area of building. By using the combined words, count of Kan and Ryang in the beam direction, they got focused on the frame of wooden structure than before.

This article is concerned with count time series taking values in non-negative integers. Along with the first order mean of the count time series, conditional variance (volatility) has recently been paid attention to and therefore various integer-valued GARCH(generalized autoregressive conditional heteroscedasticity) models have been suggested in the last decade. We introduce diverse integer-valued GARCH(INGARCH, for short) processes to count time series and a real data application is illustrated as a case study. In addition, zero inflated INGARCH models are discussed to accommodate zero-inflated count time series.

In this paper, the computational problems of packet transmission probability (PTP) in a computer communication network (CCN) under flooding routing are investigated. To avoid a congestion under this routing, two control methods are considerd, i. e., copy storage control and hop count control. Problems of PTP under flooding routings with these two control methods are respectively shown to be equivalent to those of source-to-terminal reliability(STR) with an exception for a case of hop count control where the hop count is less than the length of the longest path. For this exceptional case, an efficient computational algorithm for PTP is developed. This algorithm is proposed as an efficient tool for the determination of hop count which satisfies a given reliability constraint. A numerical example illustrates a proposed algorithm.

This study was carried out to investigate the relationship between the water resistance and the air permeability. The results are as follows; 1. In case of the water proofing fabrics, We cannot find that there is any relationship between the water resistance and the air permeability according to the kinds of finishing, while in case of the water repellent finished fabries, we can find that there is a correlationship between them, especially the hydrostatic pressure and the air permeability are found to have negative correlation. 2. In case of the water proofing fabrics, the relationship between the water resistance and the air permeability is not affected by the thickness of the fabrics. On the other hand, in case of the water repellent finished fabrics, the relationship between them is affected by the thickness of the fabrics. Especially, the relationship between the hydrostatic pressure and the air permeability as well as the relationship between the water repellency and the air permeability is effect much by the thickness of the fabrics, too. 3. In case of the water proofing fabrics, the relationship between the water resistance and the air permeability is not affected by fabric count. On the otherhand, in case of the water repellent finished fabrics, the relationship between them is affected by the fabric count. Especially, the relationship between hydrostatic pressure and the air permeability, and the relationship between the water proof and the air permeability are affected much by fabric count.

Effects of rotor-stator blade count ratio on the unsteady aerodynamic characteristics of a cascade was studied by using a Navier-Stokes code. Present Navier-Stokes code is a parallel code and works on a multi-cpu machine. It is based on the SIMPLE algorithm and uses QUICK scheme for convection terms and second order back difference for all temporal derivatives. Computations were carried out for two cases : case 1 is for 3 stator cascade passages subjected to two upstream wakes while case 2 is for 2 stator cascade passages subjected to three upstream wakes. Numerical solutions show that rotor-stator blade count ratio plays a significant role in the unsteady aerodynamic characteristics of the stator cascade. Case 2 shows smaller unsteady fluctuation than case 1, even if they show the same time averaged value. The smaller fluctuation of case 2 is believed due to strong interaction between unsteady vortices. The unsteady lift variation of case 2 is shown to have many high frequency fluctuations as more unsteady vortices travel around the cascade. The unsteady turbulent kinetic energy due to the upstream wake is also shown to decay faster through the cascade passage than in the free stream.

Objectives: This study demonstrated the positive effect of herbal medication on a suspected idiopathic thrombocytopenic purpura (ITP) patient-a 57-year-old male with suspected ITP and a decreased platelet count. Methods: The patient was treated with an herbal medicine named Nokyongdaebo-tang, and its effect was measured with periodic platelet blood tests. Results: Before taking the herbal medicine, the patient's blood platelet count was 98 K/μl, but following treatment, the blood platelet count increased to 201 K/μl and maintained a continuously elevated level. Conclusion: The results indicated that herbal medication may improve the blood platelet count of suspected ITP patients.

In the Gen-2 Q-algorithm, the values of weight C, which is the parameter for incrementing or decrementing the slot-count size, are not optimized in the standard. However, the standard suggests that the reader uses small values of C when the slot-count is large and larger values of C when the slot-count is small. In this case, if the reader selects an inappropriate weight, there are a lot of empty or collided slots. As a result, the performance will be declined because the frame size does not converge to the optimal point quickly during the query round. In this paper, we propose a scheme to select the weight based on the slot-count size of current query round. Through various computer simulations, it is demonstrated that the proposed scheme achieves more stable performances than Gen-2 Q-algorithm.

Objective : Stroke is one of the most common causes of death in Korea. This study was done to evaluate the association of complete blood count (CBC) with the risk of hemorrhagic stroke and ischemic stroke. Methods : In 217-case patients with ischemic stroke or hemorrhagic stroke and 146 healthy control subjects without stroke, hypertension, diabetes mellitus, hyperlipidemia, or ischemic heart disease and 160 controls without ischemic stroke or hemorrhagic stroke, we tested and compared white blood cell count (WBC), red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct) and platelet. These data were statically analyzed by general linear models and binary logistic regression analysis to get each adjusted odds ratio. Results :The level of WBC was significantly higher in all cases. The level of RBC, Hct and Hgb was significantly lower in patients of ischemic stroke. The level of platelet was significantly higher in patients of ischemic stroke. Conclusion : These results suggest high WBC may be a risk factor of hemorrhagic stroke and ischemic stroke and low RBC, low Hct, low Hgb and high platelet may be risk factors of ischemic stroke in Koreans.
