Objectives: The purpose of this study is to evaluate the effectiveness of herbal medicine for recovery and treatment of cervical intraepithelial neoplasia (CIN) after loop electrosurgical excision procedure (LEEP). Methods: We searched two english, one chinese and four korean database up to November 4, 2019. Randomised controlled trials (RCTs) were eligible. Primary outcome included Human papilloma virus (HPV) clearance rate and the effective ratio of treatment. And vaginal bleeding time and volume, improvement of symptoms, and recovery of wound were regarded as secondary outcomes. The risk of bias was assessed by two independent authors using the Cochrane risk of bias tool. Results: Of 47 screened, 10 RCTs were included. Number of participants per study ranged from 58 to 360. The studies which used HPV clearance rate as primary outcome were considered as low risk of bias. Most of the studies had considerable heterogeneity in terms of type of intervention, comparison and time-points for outcome measurement. Compared to LEEP alone, herbal vaginal suppository combined group showed favorable results for HPV clearance in patients (5 studies, n=627, 95% CI 1.26 to 1.55, I²=75%). And compared to LEEP alone, herbal external application also showed favorable results for HPV clearance in patients (2 studies, n=252, 95% CI 1.19 to 1.61, I²=86%). Three studies reported mild and temporary adverse events, and no serious adverse events were reported. Conclusions: The studies showed that herbal medicine can significantly effective on recovery of CIN after LEEP. However, included studies suffered from incomplete reporting, high or unclear risk of bias and substantial heterogeneity between studies. In the Future, further high-quality RCTs are needed to prove effectiveness of herbal medicine for CIN after LEEP and reduce the risk of bias.

'Visual segment surface' means a surface that extends from the missed approach point of non precision approaches (or the decision altitude location for approaches with vertical guidance and precision approaches) to the threshold to facilitate the identification of and protection from obstacles in this visual segment of the approach. Validation is the necessary final quality assurance step in the procedure design process, prior to publication. The purpose of validation is the verification of all obstacle and navigation data, and assessment of flyability of the procedure. This paper shows how to apply the protection for the visual segment of the approach procedure, and the results of the validation for visual segment surface conducted at an airport.

The purpose of this study was to analyze kinematic techniques in the woman's 100m hurdle. In order to find the kinematic parameters, a 3-D video system for kinematic analysis-kwon3d 3.1(Kwon3D Motion Analysis Program Version 3.1)-was used. Eight JVC video cameras(GR-HD1KR) were used to film the performance of Lee Yeon-Kyoung at a frame rate of 60fields/s. The kinematic characteristics from the first hurdle to last hurdle were analyzed at the clearing hurdle spots such as distance, velocities, heights and angles. The real-life three-dimensional coordinates of 20 body landmarks during each phases were collected using a Direct Linear Transformation procedure. After analyzing the kinematic variables in the 100m hurdle run, the following conclusion were obtained; Lee Yeon-Kyoung had to maintain constant stride lengths between hurdles and increase takeoff distance before clearance and shorter landing distance after clearance. She also had to hit the correct takeoff point in front of the hurdle and extend the lead leg at the moment of landing in order to minimize the loss of velocity. She had to sprint between hurdles as fast as possible over 8m/s and run powerful first stride and shortened third stride preparing for the following hurdle clearances.

The fact that colloidal particulates of rdaiogold are mainly and effectively eliminated from the blood stream by phagocytic activity of Kupffer's cells of the liver has been successfully adopted to the diagnosis if certain liver diseases and the same principle has opened a new avenue to the study of the organ by obtaining scan. Indeed, the latter procedure has been widely used for the detection of space-occupying lesions of cirrhosis of the liver. Nevertheless problem of differential diagnosis of monochromatic "cold" areas or "mottling" of the internal structure on the scan limited the value of this diagnostic modality. The present investigation is aimed at improving intepretation of photoscan findings with the aid of blood clearance rate of the intravenously injected colloidal $^{198}Au$.

An economic procedure of selective assembly is proposed when a product is composed of two mating components. The major qualify characteristic of the product is the clearance between the two components. The components are divided into several classes prior to assembly. The component characteristics are assumed to be independently and normally distributed with equal variance. The procedure is designed so that the proportions of both components in their corresponding classes are the same. A cost model is developed based on a quadratic loss function and methods of obtaining the optimal class limits as well as the optimal number of classes are provided. Formulas for obtaining the proportion of rejection and the unavailability of mating components are also provided. The proposed model is compared with the equal width and the equal area partitioning methods using a numerical example.

The bouncing of a cantilever with the free end pressed against a stop can create high-frequency vibration that the Bernoulli-Euler beam theory is inadequate to solve. An analytic procedure is presented using Timoshenko beam theory to obtain the non-linear response of a cantilever supported by an elastic stop with clearance at the free end. Through a numerical example, the bouncing behavior of the Timoshenko and Bernoulli-Euler beam models are compared and discussed.

The restraining characteristics for the single square drawbead are discussed. The drawbead restraining forces adn maximum strains by the various drawing angles are measured experimentally. During this procedure , the drawing angles are varied from 0$^{\circ}C$ to 60$^{\circ}C$. Also, the wide range of experimental data of the drawing forces and maximum strains for the various drawbead dimensions, dimensions, clearances and blank holding forces are preseted.

Basic equations and its solution procedure are derived for the analysis of an annular pump seal in which the rotor has a large static displacement from the centered position. The Bulk-flow is assumed for a control volume set in the seal clearance and the flow is assumed to be completely turbulent in axial and circumferential direction. Moody's wall-friction-factor formula is used for the calculation of wall shear stresses in the control volume. For the reaction force developed by the seal, linearized zeroth-order and first-order perturbation equations are developed for small motion about an eccentric position. Flow variables are expanded by using Fourier series for the solution procedure. Integration of the resultant first-order pressure distribution along and around the seal defines the 12 elements of rotordynamic coefficients of the eccentric annular pump seal. The results of leakage and rotordynamic coefficients are presented and compared with the Marquette's experimental results and the San Andres' theoretical analysis.

Recently international trade environment has been rapidly changed according to information age. In particular, international trade has been carried out with various ways under the digital revolution. In this regard, the companies are handling their business with the open network internet and doing their critical marketing activities which are very different from the existed trade customs. However, trade-related information database which is necessary to import and export activities is partly built, and there are many issues to be settled down. In other words, electronic trade opportunity website in the field of overseas marketing and customs clearance with EDI(electronic data interchange) are developed, but the database which companies can make use of their businesses is not fully supported. Therefore the structured database should be developed urgently from the stage of opening business to that of payment. This study closely analyzes the databases under the trade procedure, look into the problems of those database and suggest the solutions of trade information databases. Finally this study provides a sort of trade infrastructure for the development of international trade by internet through the building of trade information.
