Purpose. To investigate the differences in the frequency of post-fitting denture check-ups based on gender, age, insurance status, denture arch, and type among patients aged 65 and above. Methods. This research analyzed 988 patients from National Health Insurance Service Ilsan Hospital's Department of Prosthodontics, who had denture fittings over the last 10 years. Variables including gender, age, insurance status and type, denture arch, and denture type were assessed. Statistical analyses were performed at a 5% significance level. Results. The study incorporated 988 dentures, revealing a median of 3 check-ups post-fitting. Male patients significantly had more visits than females (P = .017), and those with full metal dentures visited significantly more than those with partial dentures (P = .005). Other variables were not significantly influential on the post-fitting check-up frequency. Conclusion. Within this study's confines, an increase in denture adjustment sessions was observed for male patients and those with full metal dentures.

Post-evaluation system reflects the results of performing a public construction project in the future similar public construction projects to be utilized in the planning. However, the current system simply compares the expected values, such as demand, B/C ratio, cost of construction, construction period, with the actual values after the completion of construction. In addition, most public owner does not actively conduct the post-construction evaluation tasks, so that the evaluation results has not been returned to early stage of a construction project. In this study, status of the post-construction evaluation system is investigated by a survey of the public owner and the construction project evaluation system of the United States and Japan was analyzed. This paper presents the improvement scheme of utilization of the results of the post-construction evaluation system. Through improving the post-construction evaluation system, it is expected that public agencies would easily utilize the post-construction evaluation.

This study suggests a few solutions to improve the post-monitoring activities under the Energy Efficiency Labeling Program. First, samples should be selected from each category for the post-monitoring activities, taking account of the consumer's continuous buying behavior, while it is also important to form and operate a deliberation committee. Second, it is necessary to alleviate the checking process of the label content of 9 items which have never been violated the labeling regulation since 2005. This study suggests the detailed checking of label contents and the reinforcement of the measurement of 17 items which have violated labeling more than once over the past few years. Third, this study suggests that the entire post-monitoring process should be disclosed and be posted on the websites of related agencies and on the Internet in general.

Various public construction projects have been performed for public welfare and appropriate evaluation of the effectiveness and efficiency has been required. In accordance with legislation of a post construction project evaluation in Construction Technology Promotion Act, all construction projects that exceed 30 billion won in budget are required to perform post evaluation. Korean Government provides post construction evaluation manual that includes both quantitative and qualitative criteria. However, it only provides general concepts and procedures not but detail guidelines for different construction project types and characteristics. Therefore, this paper developed a standard format for qualitative evaluation using survey through analyzing previous cases and research. As a result, the developed standard for survey can be applied for most civil and architectural facilities. However, it will need further research regarding establishment of detailed evaluation criteria for each type of facilities and data storage system for feedback.

The purpose of this study was to verify the impact of cognitive factors and GSR on the task performance. For this study 64 students participated. Multiple regression and repeated measures were applied to analyze the data. The result for the survey indicated that previous knowledge, physical efforts, and task difficulty had significant impacts on task performance. Particularly, task difficulty has a negative impact. This can be interpreted as someone who has high prior knowledge inputs higher physical efforts with low task difficulty perception will show high performance. On the other hand, the low arousal level of GSR in the evaluation stage is a prediction variable of task performance. This result shows that high prior knowledge and low arousal level of GSR produces high performance. However, the analysis of difference in GSR between learning and evaluation stages does not show significant difference. It suggests that physiological measure such as GSR is reliable index of cognitive load; however, it partially represents cognitive load. Other crucial factors should be added for comprehensive measures.

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.

This study analyzed international case studies on Strategic Environmental Assessment (SEA) follow-up and suggested implications based on the study's findings to aid implementation of SEA follow-up in Korea. SEA requires follow-up in order to identify unforseen adverse effects and enable appropriate remedial action to be taken. Tool kits and methodological framework for effective SEA follow-up are only being researched recently. Based on the study's findings, following implications for implementing SEA follow-up in Korea were drawn. First, the system of carrying out SEA follow-up would be different depending on the PPP topic. During the scoping stage, significant impacts should be identified according to the PPP topic, and thus help determine the indicators to be developed in the later stage. Secondly, responsibility, method, time, intervals and actions from SEA follow-up may vary depending on the target SEA consultation. Thirdly, the indicators of SEA follow-up may be considered together with various environmental standards and current political, social and economic indicators which are a big issue in society. Fourthly, SEA follow-up can be used as an integration system of its target planning and environmental planning. Finally, SEA feedback system should be needed. The result of SEA follow-up should be used for target PPP. These would lead to improvements to the target PPP. If SEA follow up is successfully implemented and actively carried out for domestic PPPs, Korea can be a step closer to realization of sustainable development.
