Natural disaster has been hard to prevent the occurrence of itself, thus in order to reduce the economic damages and loss casualties, it is important to be prepared in cases that the disasters should occur in advance. Interest of the related project to prevent various natural disasters has been grown along with an investment in Korea. Along with this movement, when investments related to natural disaster prevention projects were built on, the post evaluation that can verify the ripple effects of those investments on the community should be emerging as an essential task. For evaluating the effects of public investment projects such as natural disaster prevention projects in this study, the related researches would continue through qualitative analyses, for example, cost-benefit analysis. Even the qualitative analysis alone cannot fully explain the effects of those projects, the diverse methods of analyzing and evaluating those effects might not have been presented in those fields. For the post evaluation of natural disaster prevention projects through the qualitative analysis, this study derived subjects that had effects on the post evaluation of natural disaster prevention projects. Also, employing the structural equation modeling (SEM), the causation between post evaluation subjects and the effects of projects were quantitatively analyzed, and the weighting factors of evaluation items were calculated respectively. Based on these results, post evaluation index formula was proposed for the natural disaster prevention projects in Korea.

In this study, the purpose is to present the foot inclination angle for realizing an image similar to that of the existing examination method and to present the clinical usefulness of the new examination method through comparison between the existing examination method and the newly designed standing foot oblique projection. A foot phantom was used, and the magnification of the image according to the angle was quantitatively evaluated by attaching a nut to the position of the cuboid of the phantom. The internal oblique image acquired using a 30° wedge was set as the standard image. And that image was compared with the images acquired by changing the angle of the foot from 20° to 65° at intervals of 5°. Image evaluation was performed by 3 radiological technologists, and qualitative evaluation using a Likert 5-point scale for evaluation items of true oblique view and quantitative evaluation of the value obtained by measuring the diameter of a nut in each image were performed as image evaluation. For data analysis, reliability analysis between the measure and comparative analysis of the average value for each angle were performed. The qualitative evaluation score for each image was 4.5 to 5 points for most questions in the case of the standard image. And 4 points or less for most questions in the images with a foot angle of 45° or less, and an evaluation score close to the standard image was obtained in the image of 50° or more. And in the quantitative evaluation, the diameter of the nut was measured to be 9.28~9.56 mm. The qualitative evaluation showed a reliability of 0.95~1.0 and the quantitative evaluation was 0.62. As a result of comparing and analyzing the average of the quantitative and qualitative average values for each angle image, the group with the average value most similar to the standard image was images obtained at 55° and 60°, and in the post-analysis, the images of both groups were the same group as the standard image(p<0.01). As a result of this study, it was found that the angle of inclination of the foot for realizing the image most similar to the existing image in the standing foot oblique projection is 55°~60°. In addition, if this test method is applied to the clinic, it is believed that it will help prevent safety accidents such as falls during the test and improve test efficiency by minimizing the movement of patients for the test.

The purpose of this study was to develop and validate the Korean version of the Classism Attitude Scale for college students (K-CAS) that measures stereotypes and prejudices about socioeconomic class(SES). In study 1, preliminary items were developed through reviewing classism related theories and literatures, analyzing qualitative data by using Consensus Qualitative Method-modified(CQR-M) and getting experts' consultation. With 440 college students data, exploratory factor analysis and reliability analysis were conducted with 14 items in study 1. In study 2, a confirmatory factor analysis and validity analysis were conducted with 400 college students. As a result, two factor structures, upper classism attitude and downward classism attitude, were confirmed. With the higher level of test-retest reliability, the criterion validity was confirmed by the significant correlations among age, subjective SES, the general belief in a just world, negative affects (depression and anxiety), hostility, and K-CAS. The incremental validity was also confirmed that K-CAS scores significantly accounted for 5% of total variation in scores of negative affects(depression and anxiety) in addition to the variables, such as age, subjective SES, house income, and the general belief in the just world. The result of this study is significant in that the developed and validated K-CAS in this study can be a useful tool for further research and prevention and intervention program development related to classism.

As the development automated vehicles(AV) actively progresses around the world, the demand for a reasonable and systematic evaluation method for AVs is increasing. Research on scenarios, evaluation procedures, and methods for evaluating AVs conducted in simulations and proving ground(PG) is actively conducted internationally. In contrast, methods and procedures for evaluations on real roads are still in their infancy internationally. Therefore, it is necessary to conduct research on evaluating AVs on real roads in preparation for future use of AVs. This study aims to define the basic direction for evaluating the driving safety of AVs on real roads. To this end, the evaluation direction and process of AVs were presented on the real roads, and qualitative and quantitative evaluation indicators were selected to evaluate driving safety. A total of 38 items were selected based on the Road Traffic Act as qualitative evaluation items for evaluating the driving safety of AVs on real roads.

This study proposed the improvement in the evaluation systems and indicators of small libraries, by analyzing the evaluation indicators of the current small libraries, domestic and foreign ones and domestic other institutions, and gathering opinions from managers of them and experts belonging to related groups, in order to enhance the management quality of small libraries and strengthen the independence of them, based on the evaluation on the activation and substantiality of them. The evaluation systems proposed by this study is divided into Track 1 evaluating small libraries and Track 2 evaluating local governments. The evaluation indicators of small libraries was simplified by eliminating the indicators found from the statistics of Track 1 (small libraries). Track 1 consists of three evaluation areas in regard to the management of small libraries, such as library management, infrastructures and services, 8 evaluation items, 10 evaluation indicators, quantitative (a total of 100 points) and qualitative (a total of 120 points) evaluation. Track 2 consists of 2 evaluation areas in regard to the establishment and enforcement of small library policies and the support for small libraries, such as library management and infrastructures, 4 evaluation items, 5 evaluation indicators and quantitative evaluation (a total of 100 points).

This study aims to analyze the effect of urban ecosystem restoration projects by evaluating the short-term restoration performance of the project sites, from both qualitative and quantitative evaluations. In this study, for the qualitative evaluation, we derived the evaluation frame from previous studies and literature. For the quantitative evaluation, the changes in ecological connectivity after the restoration project were described using landscape permeability and network analysis. In addition, changes in habitat quality after the restoration project were evaluated by using InVEST Habitat Quality Model. These evaluations were applied to the three natural madang (ecological restoration) projects and two ecosystem conservation cooperation projects. As a result, three categories, 10 indicators, and 13 sub-indicators were derived from literature as the evaluation frame for this study. In the case of quantitative evaluation of restoration performance, habitat quality increased by 45% and ecological connectivity by 37% in natural-madang, and habitat quality by about 12% and ecological connectivity by about 19% in ecosystem conservation cooperation projects. This implies that the ecological restoration project can increase the ecological connectivity and the habitat quality of degraded sites even in a short period of time by improving the land-cover and land use. The results by applying the evaluation frame indicated that ecological and environmental factors and the ecological functions were improved by the restoration works, even though the magnitude of performances were diverse depending on the specific evaluation items, project type, and site characteristics. This study clarified that the success of ecological restoration project should be assessed by both of the short-term and long-term goals, which can be achieved by the maintenance and sustainable management, respectively.

The quality of service on urban roadways have been evaluated mainly based on such quantitative measures as travel speed and delay. However, in addition to the quantitative aspects, drivers traveling on urban roadways are subject to be influenced by qualitative measures such as aesthetic aspects of the roadway and other drivers' violation of traffic laws. Based on this notion, this study attempts to identify roadway service quality indices, considering both qualitative and quantitative aspects and evaluate the quality of service using the modified Importance-Performance Analysis (IPA), a technique often applied in the field of marketing. The modified IPA is proposed in this study as a way to evaluate the service quality, reflecting the relative performance between study areas and performance indices. A case study is implemented over the Gangnam and Gangbuk areas in Seoul, resulting in identifying the items needed to be improved for each study area.

Purpose: The purpose of the study was to understand and describe the hospital workers' experience related to the hospital evaluation program implemented in Korea between 2004 and 2009. Methods: During 2010, data were collected using focus group interviews. Four focus group interviews were held with a total of 28 hospital workers participating. All interviews were recorded and transcribed as they were spoken, and data were analyzed using qualitative content analysis. Results: Nine themes emerged from the analysis: 1) Positive change in the necessity of the evaluation; 2) Improvement in the hospital system, facilities, and human resources; 3) Unity through cooperation among departments; 4) Nursing work overload; 5) Lack of physicians' awareness and responsibilities; 6) Unfair and unrealistic evaluation items; 7) Lack of credibility of the outcome; 8) Shifting responsibility for negative outcomes to the workers; 9) Lack of pragmatic utility. Conclusion: The results of the study demonstrate that the hospital evaluation program played a key role in improving some work environments and communication among departments. At the same time, they show various negative themes resulting from the context of very authoritarian hospital systems and a connection-oriented society in Korea.

This study comprehensively reviewed and summarized the research on the qualitative assessment tools of elderly leisure activities. 232 papers were searched in three databases, domestic and foreign, and nine were selected to meet the selection criteria. Five out of nine studies (55.5%) have been written in the last five years and have been implemented in six countries. As for the number of questions in the evaluation tool, 20 to 40 items were the most with 6 studies (66.6%), and 7 out of 9 studies used a 3-7 point Likert scale. There were a total of 37 variables related to leisure activities, and the most variables related to mental. Previously developed evaluation tools were biased toward the measurement of specific variables or did not fit the domestic situation. In the future, various variables of leisure activities for the elderly can be measured qualitatively, and a wide range of instruments that reflect the characteristics of the elderly in Korea should be developed.
