This study was conducted to evaluate the internal quality of Korean red ginseng using a VIS/NIR spectral data. Internal qualities of Korean red ginseng were classified into normal, half whit core and white core red ginseng according to different colors of internal tissues. The objective of this study was to evaluate the internal quality of red ginseng by analyzing the transmittance spectrum of the ginseng. To evaluate the internal quality, ANN (Artificial Neural Network) model was developed. In order to save the processing time of data and to increase the quality evaluation performance for including a lot of data point of each spectrum, conducted for the various step size and epochs. The best way to evaluate of internal quality shows the combination of 15 step and 20,000 epochs. The results of performance showed the MSE (Mean Square Error) of 2.9×10-3 value and the estimation accuracy of 92.5% for unknown samples.

Purpose: The objective of this study was to evaluate the risk factors associated with agricultural machinery-related injuries, and to develop strategies to control and prevent such injuries. Methods: The medical records of 148 patients who visited the emergency department of Chosun University Hospital with a history of agricultural machinery-related injuries from January 2005 to December 2006 were examined. Injury rates were categorized by age, sex, underlying disease, place and time of injury, mechanism of accident, kind of machine and final diagnosis, Injury severity was calculated by using TRISS method and compared. Results: 148 cases of agricultural machinery-related injuries were identified. Most cases involved men(85.1%) and occurred between 4 p.m. and 8 p.m., with seasonal peaks in autumn and spring. The largest number of cases involved men in their sixties(33.2%) with a mean age of 57.5. Significant risk factors for injury were age over fifty, transferred patient, accident on main road , and patients of passenger seat or trunk when the accident occurred. Extremities were more vulnerable than other body areas, and injuries of the abdomen, head, and neck had higher fatality and mortality rate. The overall mortality rate was 12.8%. Conclusions: Agricultural machinery-related injuries have a high case fatality rate. Physicians must be able to make rapid, accurate assessments of the injured farmer, taking into account environmental factors that may cause additional problems, and active care of the injured farmer must be initiated at the rural hospital in order for optimal recovery to take place. There will be a need to develop strategies for prevention of these injuries and for educational programs.

Nowadays we globally recognize the importance of the environmental preservation and the environmental energy. The developed countries have already made efforts to realize the saving of energy and the technology based on environment-friendly viewpoint. 'Roof garden' means the restoration of soil eco-system destroyed by rash urbanization and construction. It can also offer the resting place to people in the city. Now it is considered as the realistic way that can solve the serious problems like heat island, pollution and flood in the city fundamentally. In this research, we found out that the following results were obtained: 1) Roof garden is used by users in various objects. Stage, meeting, event, date etc. 2) Users want to design roof garden that have various space features: open and close space, wide and small space etc. 3) The group composed from one to five or more played roof garden. 4) The roof garden aboved have similar facilities excepted one or two. Vaitalization in roof garden remains as a matter to be discussed further.

Recently, the Specified streets are designated in the many cities. The specified street is formed naturally by gathering the same type of shops in the same street. The purpose of the specified street is to enhance and to make more lively the characteristics of the street. These specified street has the network consisted of elements, namely shop owner, the authorities, the consumers, etc. In the beginning, we examined how specific streets are made and composed in Seoul and Inchun: the street of the culture, the rodeo, and the furniture. As it turned out, the formation of the network organization in the specific streets showed that how much it is important that it impacted managing. The members of network work together for improvement of the street by negotiation and cooperation. In that process, the street scenery is also improved. This network promotes the spontaneous participation of the members of the affair. In the result of that, the effect of the network is a core which is one of the factors managing and improving specific street. A continuous examination of the more study would strengthen the importance of the network in changing specific street construction.
