This study investigated the formation of silhouette and hemline shape of knit flare skirts according to the properties of knit material through virtual clothing with a 3D virtual clothing system called i-Designer of Technoa, thus building a database of the property data of knit material to reduce the number of sample making steps repeated and implemented several times in the process of clothes making. The results would help to estimate a silhouette in advance, offer assistance to the development of original knit wear, and explore ways to provide basic data for the development of the knit industry of the nation. The investigator made 12 kinds of experimental clothes to the angles(width of skirt: $90^{\circ}$ and $180^{\circ}$), gauge(7G, 12G, and 15G), and grain directions(wale and bias direction) of experimental clothes for virtual clothing. The dynamic characteristics of knit skirt samples according to each gauge were measured with the KES-FB system. Draper shapes were analyzed with the sectional shape data of hemline based on i-Designer. As for the measurements of the sectional shape of hemline and the formation of silhouette, the number of nodes, the average height of node mountains and valleys, and the hemline width right and left and before and after increased at the angle of $180^{\circ}$ than $90^{\circ}$. As gauges multiplied, the number of nodes, and silhouette angle dropping. When considering grain directions, the number of nodes and silhouette index increased in the wale direction at the angle of $90^{\circ}$ with the number of nodes and silhouette angle increasing in the wale direction at the angle of $180^{\circ}$.

With execution of the social care insurance for the elderly, it has been an issue of raising professionally trained care workers. The importance of building social care employees has already been emphasized in Korean and Japan. The purpose of this study is to empirically survey the job satisfaction of care workers toward workers of nursing homes and care institutions in osaka city of Japan and 150 care worker in Gyeongsangnam-do of Korea were sampled and interviewed to collect informations about the job satisfaction of care workers toward care insurance system for a questionnaire. The results of this survey as follow; basic recognition of care workers on the care insurance system change seems to be low. And then job satisfaction of care workers is high. But it was found that job stress level was relatively high. There wasn't statistically significant difference in job satisfaction and job stress than personal characteristics and job characteristics. But There was statistically significant difference in job satisfaction and job stress by nation.

This study explored the possibility of building a statistical model predicting difficulty of mathematics test items through the analysis of nation-wide scholastic ability test results for the past 5 years. Multiple linear regression analysis was conducted in predicting difficulty of mathematics test items. We adopted three major areas for independent variables: the content area, the behavior area, and the test item format area, each of which was categorized into more detailed sub-areas. For the dependent variable, the proportion of correct answer was used to represent the item difficulty. Statistically significant independent variables were included in the regression model based on the stepwise selection method. Several important factors affecting difficulty of mathematics test items for each area were identified. R-squares for the final regression model were fairly high, implying that the regression equation can be used to predict difficulty of test items at an acceptable level. Lastly, the regression model was cross-validated using independently collected data. We believe that this study will provide basic but very critical information for predicting the proportion of correct answer by showing the factors that should be considered for developing mathematics test items for the college entrance examination or high school classroom test.

In literature, it has been widely accepted that knowledge management (KM) success ratio in private companies depends on the corporate size and type of industries. However, there are few studies concerning the procedures about building knowledge management system in state-run corporations. Especially. as the Korean Government advocated the slogan saying. The Strong Nation with Knowledge and Information, the need to investigate the knowledge management case about state-run corporations instead of private companies becomes more urgent. In this respect, this paper is aimed at introducing how knowledge management system has been successfully incorporated in KAMCO, and summarizing several fact findings which are deemed noteworthy for other similar studies.

This study used the characteristics of the knowledge discovery and data mining algorithms to develop tailored hypertension follow up management model - hypertension care predictive model and hypertension care compliance segmentation model - for hypertension management using the Korea National Health Insurance Corporation database(the insureds’ screening and health care benefit data). This study validated the predictive power of data mining algorithms by comparing the performance of logistic regression, decision tree, and ensemble technique. On the basis of internal and external validation, it was found that the model performance of logistic regression method was the best among the above three techniques on hypertension care predictive model and hypertension care compliance segmentation model was developed by Decision tree analysis. This study produced several factors affecting the outbreak of hypertension using screening. It is considered to be a contributing factor towards the nation’s building of a Hypertension follow up Management System in the near future by bringing forth representative results on the rise and care of hypertension.

In every country, land has always been considered a particularly important resource and property. For Vietnam, a populous country with a relatively narrow cultivated land, the land is even more valuable because property is scarce in the process of building and developing the nation. Therefore, land administration is highly valued by the Vietnamese government and is a big priority. The study of land law and land policy in Vietnam from 1945 to present is a comprehensive view of the changes in land administration policy in Vietnam in each historical period. The study also provides the experiences and lessons learned in the field of land law and land administration in a country that has risen from the ashes of war, has accomplished reunification and has transformed from a centrally-planned economy, a feature of the communist economy, to a socialist-oriented market economy.
