Purpose: The objectives for this study are to produce the comprehensive management indexes and find their application strategies for appropriate medical care in primary care clinics under workers' compensation insurance. Method: Data of this study was workers' compensation insurance medical fees claim's data from July 2006 to June 2007. Data were analyzed using SAS 9.1 version by applying descriptive statistics and Pearson's correlation. The indexes such as costliness index(CI), standard medical fee were calculated based on the fourth revision of korean classification of diseases(KCD-4.). Results: The CI, visiting index(VI), outliers index(OI), and medical review adjustment percentage were positively correlated in the both inpatient and outpatient medical fees in primary care clinics under workers' compensation insurance. The major medical specialities were neurological surgery, general medicine, general surgery, rehabitational medicine, and orthopedic surgery. The CIs were slightly high in rehabitational medicine among major medical specialities. The CIs were mostly high in diagnosis, test, anesthesia, and rehabitational assistive device fees among major medical specialities. The CIs were slightly high in Kwangju, Daegu, Daejeon, and Busan districts among district management centers of Korea Workers' Compensation and Welfare Service. Conclusions: We suggest the continuous development of appropriate disease classification system and medical care quality indicators to successfully take root the comprehensive management for appropriate medical care under workers' compensation.

The purpose of this study was to develop prediction models for plant species abundance by stream restoration. Generally the stream plant is affected by stream gemophology. So in this study, the relationship between the vegetation abundance and stream gemophology was developed by multiple regression analysis. The stream characteristics utilized in this study were longitudinal slope, transectional slope, micro-landforms through the longitudinal direction, riparian width and geometric mean diameter and biggest diameter of bed material, and cumulated coarse and fine sand weight portion. The Pyungchang River with mountainous watershed and the Kyungan stream and the Bokha stream in the agricultural region were selected and vegetation species abundance and stream characteristics were documented from the site at 2~3km intervals from the upper stream to the lower. The Models for predicting the vegetation abundance were developed by multiple regression analysis using SPSS statistics package. The linear relationship between the dependant(species abundance) and independant(stream characteristics) variables was tested by a graphical method. Longitudinal and transectional slope had a nonlinear relationship with species abundance. In the next step, the independance between the independant variables was tested and the correlation between independant and dependant variables was tested by the Pearson bivariate correlation test. The selected independant variables were transectional slope, riparian width, and cumulated fine sand weight portion. From the multiple regression analysis, the $R^2$for the Pyungchang river, Kyungan stream, Bokga stream were 0.651, 0.512 and 0.240 respectively. The natural stream configuration in the Pyungchang river had the best result and the lower $R^2$for Kyunan and Bokha stream were due to human impact which disturbed the natural ecosystem. The lowest $R^2$for the Bokha stream was due to the shifting sandy bed. If the stream bed is fugitive, the prediction model may not be valid. Using the multiple regression models, the vegetation abundance could be predicted with stream characteristics such as, transection slope, riaparian width, cumulated fine sand weigth portion, after stream restoration.

High quality publicly-available transcriptomic data representing relationships in gene expression across a diverse set of biological conditions is used as a context network to explore transcriptomics of the CNS. The context network, 18367Hu-matrix, contains pairwise Pearson correlations for 22,215 human genes across18,637 human tissue samples1. To do this, we compute a network derived from biological samples from CNS cells and tissues, calculate clusters of co-expressed genes from this network, and compare the significance of these to clusters derived from the larger 18367Hu-matrix network. Sorting and visualization uses the publicly available software, MetaOmGraph (http://www.metnetdb.org/MetNet_MetaOm-Graph.htm). This identifies genes that characterize particular disease conditions. Specifically, differences in gene expression within and between two designations of glial cancer, astrocytoma and glioblastoma, are evaluated in the context of the broader network. Such gene groups, which we term outlier-networks, tease out abnormally expressed genes and the samples in which this expression occurs. This approach distinguishes 48 subnetworks of outlier genes associated with astrocytoma and glioblastoma. As a case study, we investigate the relationships among the genes of a small astrocytoma-only subnetwork. This astrocytoma-only subnetwork consists of SVEP1, IGF1, CHRNA3, and SPAG6. All of these genes are highly coexpressed in a single sample of anaplastic astrocytoma tumor (grade III) and a sample of juvenile pilocytic astrocytoma. Three of these genes are also associated with nicotine. This data lead us to formulate a testable hypothesis that this astrocytoma outlier-network provides a link between some gliomas/astrocytomas and nicotine.

This study was performed to offer convenience to determine the vertical dimension of occlusion of edentulous patients by investigating the interocclusal distances at physiologic rest position, at speaking of /m/ sound, and some korean short sounds, that is, /mem/ and /beb/ sounds, which were found in our previous study with dentulous subjects. Ten edentulous subjects - 6 men and 4 women - were selected for this study. The frequencies at speaking of /m/, /mem/, and /beb/ sounds were analyzed with Computerized speech lab($CSL^{TM}$, Model 4300B, Software version 5.X, Kay Elemetrics Co. U.S.A.). And the interocclusal distances at physiologic rest position and at speaking of /m/, /mem/, and /beb/ sounds were measured with K6 diagnostic system(Myo-tronics, Inc. U.S.A.). The results of this study were as follows ; 1. In the acoustic analysis by Computerized speech lab, frequencies of sounds of edentulous subjects with complete denture at speaking of /m/, /mem/, and /beb/ were similar to those of dentulous subjects. 2. In the linear correlation by Pearson's correlation coefficient, the interocclusal distance at physiologic rest position was most similar to those of speaking /mem/ sound, secondly /m/ sound, and thirdly /beb/ sound(p<0.05). In reliability by Cronbach's alpha, the results were reliable with alpha value 0.97. 3. It was found by Levene's test for equality of variance that the difference between men and women in the interocclusal distances at physiologic rest position and at speaking of /m/, /mem/, and /beb/ sounds was not statistically significant(p>0.05).

The purpose of this study was to assess current food-handling practices of employees in school food service settings, as well as their knowledge levels, and identify relationships between knowledge, practices, and influencing variables. The survey was conducted for dietitians and employees in the school foodservice industry in Gyeongsangbuk-do province. A total of 270 and 570 questionnaires for dietitians and employees, respectively, were distributed by mail. Response rates were $62\%$ (N=171) and $66\%$ (N=376) from dietitians and employees, respectively. Data was analyzed using SPSS Windows (version 10.0). Descriptive statistics were used to summarize data. Pearson correlations were applied to test for relationships between knowledge and practice of HACCP principles. Stepwise regression analysis was performed to examine the influence of knowledge, current education guidelines, demographic information (working experience, academic background, and certification for food and cooking), and school characteristics (food production system, service style, and number of meals). School foodservice employees were found to have a significant amount of food safety knowledge ($67.5\pm1.8$ out of 100 possible points). Proper food handling practices were not always being followed in many schools. The relationship between their knowledge, current HACCP education training, and food handling practices was not significant. These results suggested the present situation of HACCP trainings performed by dietitians were inadequate for many school foodservice operations. The number of meals in school was an independent predictor of the employees' food-handling practices. These results suggest that an effective education program should integrate endeavors that take account of social and environmental influences on food safety to support the improvement of food-handling practices and the implementation of a HACCP program. Furthermore, dietitians should continue to provide consulting, training, and technical assistance to schools on HACCP implementation.

We estimated the spatio-temporally distributed soil moisture using Sentinel-1A/B SAR (Synthetic Aperture Radar) sensor images and soil moisture data assimilation technique in South Korea. Soil moisture data assimilation technique can extract the hydraulic parameters of soils using observed soil moisture and GA (Genetic Algorithm). The SWAP (Soil Water Atmosphere Plant) model associated with a soil moisture assimilation technique simulates the soil moisture using the soil hydraulic parameters and meteorological data as input data. The soil moisture based on Sentinel-1A/B was validated and evaluated using the pearson correlation and RMSE (Root Mean Square Error) analysis between estimated soil moisture and TDR soil moisture. The soil moisture data assimilation technique derived the soil hydraulic parameters using Sentinel-1A/B based soil moisture images, ASOS (Automated Synoptic Observing System) weather data and TRMM (Tropical Rainfall Measuring Mission)/GPM (Global Precipitation Measurement) rainfall data. The derived soil hydrological parameters as the input data to SWAP were used to simulate the daily soil moisture values at the spatial domain from 2001 to 2018 using the TRMM/GPM satellite rainfall data. Overall, the simulated soil moisture estimates matched well with the TDR measurements and Sentinel-1A/B based soil moisture under various land surface conditions (bare soil, crop, forest, and urban).
