Although the forest accounts in Korea have been constructed partly as the research projects since the mid-1990s, the framework of the accounts has not yet been established. The objective of this study is to provide the physical asset accounts of forested land and forest stock based on the system of integrated environmental economic accounts(SEEA) by utilizing the restructured 2004 statistical yearbook of forestry in Korea. In 2004 yearbook, new variables such as logging area and volumes are added. The logging area and volumes play important roles in constructing forest accounts because the basic structure of the physical asset accounts are composed of the opening stock, closing stock, and the changes between the two. The changes between the opening and closing stock are largely explained by the harvest. In forest accounts, in general, the main elements for the increase in stock are afforestation and reforestation while the main cause for the decrease is logging. In this study we separate the logging into natural or man-made causes. In addition, other useful information for the status of forest is recorded in an annex even if it is not necessary element in the account table. According to the forested land asset accounts generated with 2003 data, the logging area is larger than the reforestation area, and the total forested land is decreased. The logging volume is 0.4% of the total stock volume, and the planed logging volume is more than 3 times larger than the damaged logging volume. The damaged logging volumes by man-made causes is about $300,000m^3$, and it is much than that of natural causes, which is about $55,000m^3$.

South Korea is a country that emits a large amount of pollutants as a result of population growth and industrial development and is also severely affected by transboundary air pollution due to its geographical location. As pollutants from both domestic and foreign sources contribute to air pollution in Korea, the location of air pollutant emission sources is crucial for understanding the movement and distribution of pollutants in the atmosphere and establishing national-level air pollution management and response strategies. Based on this background, this study aims to effectively acquire spatial information on domestic and international air pollutant emission sources, which is essential for analyzing air pollution status, by utilizing high-resolution optical satellite images and deep learning-based image segmentation models. In particular, industrial parks and quarries, which have been evaluated as contributing significantly to transboundary air pollution, were selected as the main research subjects, and images of these areas from multi-purpose satellites 3 and 3A were collected, preprocessed, and converted into input and label data for model training. As a result of training the U-Net model using this data, the overall accuracy of 0.8484 and mean Intersection over Union (mIoU) of 0.6490 were achieved, and the predicted maps showed significant results in extracting object boundaries more accurately than the label data created by course annotations.

Many companies in Korea have developed job competency models and are utilizing them for the purpose of training and management of employees. However many of them are unable to be utilized efficiently through their own job competency model because the company failed to reflect what happens in the real work place in the model or the model itself is not concrete enough to be applied practically. Thus, in this study, the current status of Korean companies which had developed their own job competency model were investigated and the subsequent development of training system which is based on the model were developed. By result of the survey, about 43.5% of the company, which has more than 400 employees, have developed job competency models and 31.7% of them haven‘t been able to develop training system based upon the model due to the lack of concreteness of their model. To overcome this contradiction, we developed web 2.0 based job competency modeling method where each individuals in the organization themselves develop job competency as opposed to an expert oriented developing method. The result of this study is that web 2.0 based job competency modeling method is superior to any another modeling in an accuracy of competency, an acceptance of competency, and an usefulness of competency description.
