Objectives: The purpose of this study was to evaluate the quality of reporting for case reports published in Journal of Oriental Neuropsychiatry from year 2018 to 2021 compared with year 2013 to 2017 in order to recommend ways to improve the quality of case reports published in the future. Methods: To evaluate the quality of case reports identified by electronic searching in Oriental medicine Advanced Searching Integrated System (OASIS) and by hand searching from archives on peer review system of Journal of Oriental Neuropsychiatry using CAse REport (CARE) guideline. The researcher assessed the quality of reporting based on the CARE guideline as 'Sufficient', 'Not-Sufficient', 'Not-Applicable', and 'Not-Reported' for case reports published from 2018 to 2021 in Journal of Oriental Neuropsychiatry. In addition, it was compared with previous case reports published from 2013 to 2017. Results: Finally, 17 case reports were included for the assessment. General quality of reporting for case reports published from year 2018 to 2021 was improved compared with that of previous case reports published in 2018. The maximum value (46.4%→60.7%, 14.3% increase), the minimum value (22.2%→32.1%, 9.9% increase), and the median value (39.3%→50.0%, 10.7% increase) of the report rate evaluated as 'Sufficient' were generally improved. The maximum value (53.6%→50.0%, 3.6% decrease), minimum value (25.9%→21.4%, 4.5% decrease), and median value (35.7%→32.1%, 3.6% decrease) of the report rate evaluated as 'Not-Sufficient', the maximum value of the report rate evaluated as 'Not-reported' (40.7%→25.9%, 14.8% decrease), the minimum value (14.7%→10.7% decrease), and the intermediate value (14.7% decrease) were also generally improved. Four items (8b, 8d, 10c, and 13) were evaluated as 'Not-Reported'. These items seem to be items that need urgent improvement along with 8c, which showed a significant decrease in reporting rate. Conclusions: There are needs to improve the quality of case reports in Journal of Oriental Neuropsychiatry by comparing case reports published from year 2013 to 2017 with case reports published from year 2018 to 2021. To improve the quality of case reporting, sufficient education at the academic level should be provided on thesis preparation methods. It is also necessary to develop a tool for evaluating the quality of case reporting that reflects characteristics of Korean Medicine.

Landscape elements of historical and cultural value and elements that have negative impact on landscape due to reckless development teem in rural area. Due to this, local government has established a visual landscape plan. The purpose of this study is to analyze the process and content of domestic rural landscape planning process and to suggest improvements for it. For that, this study measure guideline of Ministry of Agriculture, Food and Rural Affairs against guideline of Ministry of Land, Infrastructure and Transport. To analyze the landscape planning guideline of australia which is similar to domestic rural landscape planning process, and to compare both guidelines. The results of this study are as follow. The stage of landscape resource survey and assessment progressed systematically, but it was not practical because for the lack of survey and assessment method. Therefore, it should be suggested for the survey and assessment technique. The rural landscape plan, established in master planning stage, do not necessarily reflect local government's landscape management on the ground of abstract technic of landscape management. For this sake, to develop evaluation method for development of landscape element seems necessary.

Six sigma is focused on quality improvement through variation reduction, while lean is on process flow improvement and lead time reduction by waste elimination. However, lean cannot bring a process under statistical control and six sigma alone cannot dramatically improve process speed. Lean six sigma was developed to achieve faster rate of improvement in customer satisfaction, cost, quality, process speed, and invested capital. In this paper we present the importance of using value stream mapping and suggest a guideline on how to integrate lean and six sigma by is proposed.

This paper describes the path planning method in an unknown environment for an autonomous mobile robot equipped with CCD(Charge-Coupled Device) camera. The mobile robot moves along the guideline. The CCD camera is useful to detect the existence of a guideline. The wavelet transform is used to find the edge of guideline. Using wavelet transform, we can make an image processing more easily and rapidly. We make a fuzzy control rule using image data then make a decision the position and the navigation of the mobile robot. The center value that indicates the center of guideline is the input of fuzzy logic controller and the steering angle of the mobile robot is the fuzzy output. Some actual experiments for the mobile robot applied fuzzy control show that the mobile robot effectively moves to target position.

In December 2006, the Ministry of Environment in Korea established the "Indoor Air Quality Management Guidelines in Public Transportation." As the items of the guideline, $CO_2$(Carbon dioxide) and PM10(Particulate matter). Therefore, the air quality inside the train is supposed to be ruled by this guideline. This study calculated the increase or decrease rate of the $CO_2$ concentration by using the data measured in accordance with flap operation. In case of flap close or open, the calculated $CO_2$ concentration variation was 6.32ppm/min. The $CO_2$ concentration prediction equation was derived from the general equation and the actual measured value are compared with the predicted $CO_2$ concentration suggested during the KyungBu high speed railway construction. The predicted value show good agreement with the measured data.
