Wind farm development project contains high business risks because that a wind farm, which is to be operating for 20 years, has to be designed and assessed only relying on a year or little more in-situ wind data. Accordingly, long-term correction of short-term measurement data is one of most important process in wind resource assessment for project feasibility investigation. This paper shows comparison of general Measure-Correlate-Prediction models and neural network, and presents new method using neural network for increasing prediction accuracy by accommodating multiple reference data. The proposed method would be interim step to complete long-term correction methodology for Korea, complicated Monsoon country where seasonal and diurnal variation of local meteorology is very wide.

This research was thereby made to study and analysis ecological, landscape, and stability qualities of roadside cut Slopes in expressways and national highways that went through revegetation works. Also, evaluation items and framework for integrated assessment of plant structure and restored state for the maintenance were suggested. Following is the summary of the result. firstly, for stabilization of introduced native plant species on roadside cut slops, assessment on the post-project environmental management through long-term monitoring and maintenance works must be made. It signifies a form of authentic recovery and restoration by the native plants. second, current evaluation framework on the test beds is well managed with clear evaluation standards and table while its method of assessing the post management with only test bed results lacks conformity with this study site. Newly developed evaluation framework on the post construction sites is estimated to be used as assessment standards on any roadside construction sites. Third, after site investigation distinction was observed among different revegetating construction types in the long-term perspective. Due to the different duration time of vegetation state between seed-spray measures(degraded in time) and layer-spray measure(maintained), the use of coarse straw-mat mulching work or Coir net was suggested in long term maintenance of cut slopes. forth, segmentation of post environmental assessment is organized into three large categories of "ecological", "stabile", and "landscape" qualities regarding post restoration quality and stability of slope through native plants with which categories marks 50, 30, 20 points of rates. fifth, components of the post environmental assessment were segmented in twelve categories driving results from former experimental construction and newly focused items on site. In the future, it is possible to propose a customized assessment method considering the location and location of construction work if the research on the application of post-environment assessment methods for road construction surface recording is conducted systematically.

Purpose: This study was conducted to explore the impact of nurse staffing level and oral care on pneumonia in elderly inpatients in long-term care hospitals (LTCHs). Methods: Data were obtained from the Health Insurance Review and Assessment Services (HIRA) including the profiles of LTCHs, monthly patient assessment reports and medical report survey data of pneumonia patients by HIRA in the fourth quarter of 2010. The sample consisted of 37 LTCHs and 6,593 patients. Results: Patient per nurse staff (OR=1.43, CI=1.22~1.68) and no oral care (OR=1.29, CI=1.01~1.64) were significantly related with hospital acquired pneumonia. The difference in percent of oral care by hospital was not significant between high and low group in nurse staffing level. Conclusion: In order to reduce the occurrence of pneumonia in eldery patients, effective nursing interventions are not only required but also nurse staffing levels that enable nurses to provide the intervention.

The purpose of this study is to develop SPA system using diagnostic and formative assessment in earth science classes in order to discuss its effect on learning achievement and self-directed learning attitude. For this purpose, we developed total management system, app for teachers, and app for students. This research was practiced to 76 students in 5th grade. The results are as follows. Firstly, the group taking a class used by app for diagnostic and formative assessment had an effect of improving learning achievement. However, as for learning achievement long term endurance test, the group taking a class using app for diagnostic and formative assessment had no effect. Secondly, the group taking a class using apps for diagnostic and formative assessment had an effect of improving learners' self-directed learning attitude. As for self-directed long-term endurance test, the group taking a class using app for diagnostic and formative assessment had an effect. In conclusion, I hope that this SPA system might apply to the science classes as it is a system that will satisfy the needs of both teachers and students, giving much needed feedback to students.

Purpose: To demonstrate the importance of comprehensive skin observation as an effective intervention for pressure injury prevention in elderly long-term care hospital patients. Methods: The survey was conducted with 70 nursing staff members working at two long-term care hospitals with 200 beds or less in D city. Data were collected from October 16 to October 23, 2019 and analyzed using descriptive statistics, the chi-square test, and the independent t-test with the SPSS 25.0 program. Results: Nursing care knowledge for pressure injury was similar between the two groups. Conversely, nursing care performance for pressure injury degree of the nursing staff in the hospital using skin observation records performed better than those who did not (t=6.11, p<.001). Furthermore, comprehensive skin assessments in long-term care hospitals using skin observation records showed a lower incidence rate of pressure injury than that showed using general skin assessments (t=-5.28, p=.006). Conclusions: Comprehensive skin assessment is important for pressure injury prevention in elderly long-term care hospital patients. To implement this effectively, it is necessary to devise institutional regulations, guidelines, and systematic education programs.

Purpose: This study was done to explore factors related to amount of service use for elders with long-term care needs. Methods: A descriptive-correlation design was used. The sample included 259 elders and their primary caregivers who had cared for the elders for at least 6 months. Data on long-term care need assessment, service use and interviews with primary caregivers were analyzed. Results: There was no significant relationship between the sociodemographic characteristics and the amount of services use. Amount of service use differed significantly by Long-term care classification. The mean scores for class 1, 2 and 3 were 22.68, 21.47 and 17.87 days respectively. Primary caregiver relationship with the elders and the number of family-friend helpers were also significant. Multivariate regression analysis showed that gender, marital status, activities of daily living, cognitive impairment, and secondary caregiver support explained 17% of the total variance of service use among these elders (F=3.50, p<.001). Conclusion: The results of this study indicate that critical factors including secondary caregiver support and individual background, and other functional dependencies except for physical function should be considered in accurately predicting the amount of service use for community dwelling elders with long-term care needs.

With South Korea increasingly focusing on nuclear energy, the management of spent nuclear fuel has attracted considerable attention in South Korea. This study established a novel procedure for selecting safety-relevant radionuclides for long-term safety assessments of a deep geological repository in South Korea. Statistical evaluations were performed to identify the design basis reference spent nuclear fuels and evaluate the source term for up to one million years. Safety-relevant radionuclides were determined based on the half-life criteria, the projected activities for the design basis reference spent nuclear fuel, and the annual limit of ingestion set by the Nuclear Safety and Security Commission Notification No. 2019-10 without considering their chemical and hydrogeological properties. The proposed process was used to select 56 radionuclides, comprising 27 fission and activation products and 29 actinide nuclides. This study explains first the determination of the design basis reference spent nuclear fuels, followed by a comprehensive discussion on the selection criteria and methodology for safety-relevant radionuclides.
