This study aimed to investigate the effect of a lap board that was developed to prevent musculoskeletal disorders caused by the use of a computer mouse. Study participants were 10 college students in their 20s who did not have any musculoskeletal symptoms. We analyzed the difference in upper limb movements, electromyographic activity, task performance, and subjective discomfort between 2 conditions: use of a mouse with the lap board and use of a mouse placed on a desk. Results of behavior analysis showed that there was a significant difference between the 2 conditions in terms of the average angle of shoulder flexion, shoulder internal rotation, and forearm pronation(p< 0.05). However, electromyographic activity, task performance, and subjective discomfort showed no significant differences between the 2 conditions. When subjects used the mouse with the lap board, their upper extremity was located much closer to the torso than when they used the mouse placed on the desk. Six of 10 participating students preferred the lap board. We expect that advanced research on prevention of musculoskeletal disorders due to the use of the computer mouse will be conducted in the near future.

After the modern industrial revolution, rivers in cities became covered and disappeared due to the pressure to develop them. Likewise, their function which is to serve as the basis of natural ecology system in the cities began to be damaged. This research demonstrated that there are a total of 268 categories when it comes to the list of plants, including 64 families, 179 genera, 230 species, 36 varieties, and 1 subspecies. When the relative abundance of the plants that were found at the target research site was studied, the secondary survey demonstrated Bromus japonicus 22.97, Artemisia princeps var. orientalis 16.76 and Erigeron annuus 15.69 while third survey demonstrated Digitaria ciliaris 26.78, Ambrosia trifida 16.29 and Aster pilosus 14.31. There were 54 species of naturalized plants that appeared. Analysis demonstrated annual plant 23 classification category (43%), perennial 11 classification category (20%), multi-perennation 17 classification category (31%), woody plant 3 classification category (6%) and others. When the naturalized plants that were found at the target research site were analyzed by the place of origin, North America and EU took up 76%, which accounts for 3/4 of the all the naturalized plants. At the target research site, naturalization degree of 5 pertained to 22 classification category (41%), which was the highest, followed by 19 classification category (35%) with naturalization degree of 3, 8 classification category (15%) with naturalization degree of 2 and 5 classification category (9%) with naturalization degree of 4 in the order mentioned. Flora of Jungnangcheon did not manifest any change compared to 10 years ago. Thus, it is necessary to increase of biodiversity efforts to improve SeoulCity's natural environment and cityscape.

Service design refers to an activity to design a user's service experience and a design area for professionally executing it. In order to design services from the people's point of view away from the supplier-oriented policy decisions in the past, the recent public participation business model using the service design methodology is increasing. In particular, the Ministry of Public Administration and Security formed the 'National Design Team' in 2014 to design services from the perspective of the public throughout the policy process. The public participatory policy model is being operated in which the public as policy consumers, service designers and public officials as suppliers participate in the overall policy process to develop and develop public services through service design techniques. This study is meaningful in that it presented the developmental direction of the actual project site through the case of the National Design Team sign improvement project with the goal of establishing a regional revitalization strategy using the service design methodology. However, as this study is about the current project, verification of the application of future project sites and user satisfaction evaluation have not been conducted. When the project is completed in the future, it is necessary to conduct a project satisfaction survey targeting consumers.

This study aims to develop an effective model of the optimum route determination by using digital terrain model. So in this study I select testing areas and analyse comparing the usual method with the digital terrain model method. And then I present one of the optimum route determination models by analysing an anticipated view and other roads according to the development plan. In usual method, the selected area was analysed by using panoramic terrestrial and aerial photograph. But in this study I represent the present terrain by using digital terrain materials which was acquired by a check form map of the selected area, and predict the route line according to the view points by using basic development plan. As a result of using the digital terrain model method in the optimum route determination with terrestrial photograph, it is possible to explain the terrain in detail when the present conditions terrain is analysed. As we can anticipated many sided road in large scale development plan with digital terrain materials which was used in analysing the present terrain, it is possible to lead to more effective route planning, landers planning and the optimum road determination than the usual method in the basic plan.

The purpose of this study is to identify the trend of the contents of the plan that was implemented through contents analysis on the master plan project of rural village development projects that began in 2004. Contents analysis is based on the classification of business in the detailed enforcement regulations of rural village development project. Analysis on the project contents was conducted for 30 days from June 20 to July 20 for the 132 regions established in the master plan during the period from 2004 to 2007. The results of the analysis showed the following. First, scenery facilities, rural tourism, cultural welfare and income basis projects accounted for 76.5% of the total projects. Second, with regard to investment costs depending on the contents of the projects, cultural welfare, rural tourism and income basis projects accounted for 66.3% of the total investment costs. Third, it was found out that, with regard to the trend of change in the project contents by year, income basis projects were sharply reduced whereas cultural welfare and scenery facilities projects were increased. Finally, with regard to the analysis on the projects by region, it was found that Gangwon, Gyeonggi and Chungnam gave high weight on rural tourism, whereas Gyeongbuk, Jeonnam and Jeonbuk gave low weight on rural tourism. Particularly, Gyeongnam was found to have given low weight on income basis project.

Trees are important ground objects that cause oxygen and reduce carbon dioxide in urban areas. For management of the trees, many studies using LIDAR data have been conducted. But, they rely on overseas developed LIDAR data processing software applications because there is a lack of domestically developed software applications. Therefore, this work was intended to propose an automation process that helps to extract trees automatically from LIDAR data. The proposed process has the function to classify LIDAR data and to extract building regions and trees automatically. It was applied to a study place in Yongin to conduct a test. As a result, about 88% of trees were extracted from the automation process.
