A foot pedal switch in the diagnosis x-ray radiography system has been researched to improve radiologic technologist works and patient satisfaction. The switch has been installed in the diagnosis x-ray radiography system used in domestic clinics. Quantitative evaluation has been conducted by measuring the exposure dose reproducibility test, tube voltage, mAs, and percentage average error. Qualitative evaluation has been conducted by analysis of the radiologic technologists questionnaire. In the quantitative evaluation for the use of the foot pedal switch, the coefficient of variation was less than 0.05 in the exposure dose reproducibility test. In the mAs test, percentage average error of ${\pm}20%$ was measured. There was no problem raised since it meets the all inspection standards of the diagnosis x-ray generator. In the qualitative evaluation, most of the opinions are that it has a clinical value for the foot pedal switch in the diagnosis x-ray radiography system. Therefore, developing the foot pedal switch for the diagnosis x-ray radiography system can improve effectively the rapidity and accuracy of the radiologic technologist work. In addition, it is effective in decreasing the x-ray exposure of patients and increasing satisfaction for the medical service due to reduction of retaking x-ray.

The government introduced the comprehensive evaluation bidding system with the goal of pursuing the best value and the global standard in 2016. However, for the evaluation criteria on the construction evaluation reflected to the comprehensive evaluation bidding system, the problems of the objectivity insufficiency, the inclusion of multiple subjective evaluation items, and the irrationality of the weight for each evaluation item are continue to be presented. The central office group, the local government, the relevant industry, and the expert group share recognition, but the solution is not derived. Hence, the major evaluation items to be improved were derived with the characteristics analyzed to secure the objectivity of the construction evaluation. For the analysis method, the standard deviation and the Fleiss Kappa analysis method were used by utilizing the characteristics that the construction evaluation criteria consist of all 4-point measures (good, average, insufficient, and poor). According to the result, the 10 evaluation items of the total 25 construction evaluation items were derived as the evaluation items to be improved. It was found in the analysis on the major characteristics of the derived evaluation items that the qualitative evaluation criteria such as 'Very Suitable' and 'Suitable' were commonly included in the detailed evaluation guidelines. Hence, as far as the future construction evaluation standards are concerned, the qualitative evaluation standards are sublated, and the improvement should be made mainly for the quantitative evaluation criteria enabling the objectivity assurance.

Along with the advancement of deep learning technology, securing high-quality dataset for verification of developed technology is emerging as an important issue, and developing robust deep learning models to the domestic road environment is focused by many research groups. Especially, unlike expressways and automobile-only roads, in the complex city driving environment, various dynamic objects such as motorbikes, electric kickboards, large buses/truck, freight cars, pedestrians, and traffic lights are mixed in city road. In this paper, we built our dataset through multi camera-based processing (collection, refinement, and annotation) including the various objects in the city road and estimated quality and validity of our dataset by using YOLO-based model in object detection. Then, quantitative evaluation of our dataset is performed by comparing with the public dataset and qualitative evaluation of it is performed by comparing with experiment results using open platform. We generated our 2D dataset based on annotation rules of KITTI/COCO dataset, and compared the performance with the public dataset using the evaluation rules of KITTI/COCO dataset. As a result of comparison with public dataset, our dataset shows about 3 to 53% higher performance and thus the effectiveness of our dataset was validated.

This paper presents the status of nutrition education for older adults in Korea, and examines considerations in developing effective nutrition education programs for the elderly based on literature reviews. Finally, strategies of nutrition education for older adults in Korea are examined. Status of nutrition education were examined by surveying 90 senior centers, and 46 public health centers providing nutrition services. Most senior centers(96%) provided health education programs, however, nutrition was only a part of health programs. Among the 41 public health centers which responded to the survey, 73.1% provided nutrition education for older adults. The frequently covered topics were prevention & management of hypertension/stroke, diabetes, nutritional management during later adulthood, and osteoporosis. Common barriers in planning and implementing elderly education were; lack of educational materials for older adults, reliance on lectures, difficulty in following-up. To develop effective nutrition education, four stages consisting of needs assessment, planning and implementation of programs, and evaluation should be carefully done. Needs assessment might be done using quantitative or qualitative assessment. Factors influencing nutrition behavior of older adults can be systematically examined using a theoretical approach such as the PRECEDE-PROCEED framework. Qualitative methods, such as focus group interviews, also provide insightful information regarding the needs of older adults. In planning nutrition education programs, physical and pshychological changes associated with aging should be considered. Literature regarding elderly education suggest that active participation or participatory learning is also effective for older adults. Educational materials are developed following the principle of KISS and pre-tested. Program evaluation has been rarely done in practice, although it provides valuable feedback to the program. Strategies for developing nutrition education for Korean elderly include; performing needs assessment, developing a standard program by topics in a logical and systematic way, developing programs for subgroups of elderly, applying diverse education methods developing educational materials for the elderly, evaluating programs using simple tools, and delivering a nutrition program as a part of health promotion program. Finally, the interaction and communication between researchers and practitioners is strongly recommended to ensure better nutrition education and services to the elderly.

Greenhouse gas(GHG) inventories were reported recently in various fields. It, however, has been rarely to mention about the accuracy and reliability of the GHG inventory results. Some reliable assessment methods were introduced to judge the accuracy of the GHG inventory results. It is, hence, critical to develop an evaluation methodology. This project was designed 1) to develop evaluation methodology for reliability of inventory results by GHG-CAPSS, 2) to check the feasibility of the developed evaluation methodology as a result of applying this methodology to two emission sources: liquid fossil fuel and landfill, and 3) to construct the technical roadmap for future role of GHG-CAPSS. Qualitative and quantitative assessment methodologies were developed to check the reliability and accuracy of the inventory results. Qualitative assessment methodology was designed to evaluate the accuracy and reliability of estimation methods of GHG emissions from emission and sink sources, activity data, emission factor, and quality management schemes of inventory results. On the other hand, quantitative assessment methodology was based on the uncertainty assessment of emission results. According to the results of applying the above evaluation methodologies to two emission sources, those seem to be working properly. However, it is necessary to develop source-specific rating systems because emission and sink sources exhibit source-specific characteristics of GHG emissions and sinks.

The width of sidewalk is one of the important factors constructing a pleasant pedestrian environment. The procedure for sidewalk width design based on the Level of Service is suggested in Korea Highway Capacity Manual. However, this manual does not give a difference between the sidewalk on the street with the passage of the subway, therefore, the different flow characteristic of these places is not appropriately reflected. Though the pedestrian flow in the subway encounters a frequent stop and go situation as like the platoon of vehicles, the similar condition is rarely observed at the urban streets. The new measure of LOS for sidewalk is in need. The study reviewed the prominent measure of LOS and carried out the outdoor experiment to evaluate the new measure. Particularity, GPS was used to collect the pedestrian foot path trajectory for the quantitative evaluation and the results from quantitative and qualitative are compared.
