  • PURPOSE. The aim of this review was to analyze the evaluation criteria on mandibular implant overdentures through a systematic review and suggest standardized evaluation criteria. MATERIALS AND METHODS. A systematic literature search was conducted by PubMed search strategy and hand-searching of relevant journals from included studies considering inclusion and exclusion criteria. Randomized clinical trials (RCT) and clinical trial studies comparing attachment systems on mandibular implant overdentures until December, 2011 were selected. Twenty nine studies were finally selected and the data about evaluation methods were collected. RESULTS. Evaluation criteria could be classified into 4 groups (implant survival, peri-implant tissue evaluation, prosthetic evaluation, and patient satisfaction). Among 29 studies, 21 studies presented implant survival rate, while any studies reporting implant failure did not present cumulative implant survival rate. Seventeen studies evaluating peri-implant tissue status presented following items as evaluation criteria; marginal bone level (14), plaque Index (13), probing depth (8), bleeding index (8), attachment gingiva level (8), gingival index (6), amount of keratinized gingiva (1). Eighteen studies evaluating prosthetic maintenance and complication also presented following items as evaluation criteria; loose matrix (17), female detachment (15), denture fracture (15), denture relining (14), abutment fracture (14), abutment screw loosening (11), and occlusal adjustment (9). Atypical questionnaire (9), Visual analog scales (VAS) (4), and Oral Health Impact Profile (OHIP) (1) were used as the format of criteria to evaluate patients satisfaction in 14 studies. CONCLUSION. For evaluation of implant overdenture, it is necessary to include cumulative survival rate for implant evaluation. It is suggested that peri-implant tissue evaluation criteria include marginal bone level, plaque index, bleeding index, probing depth, and attached gingiva level. It is also suggested that prosthetic evaluation criteria include loose matrix, female detachment, denture fracture, denture relining, abutment fracture, abutment screw loosening, and occlusal adjustment. Finally standardized criteria like OHIP-EDENT or VAS are required for patient satisfaction.

  • The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

  • Legislation on pharmaceutical reimbursement decision using economic evaluation results was made in Korea in fm, but has yet to be fully implemented. We evaluated the quality of Korean economic evaluation studies of pharmaceuticals to understand gaps between legislation and implementation. From this evaluation, we propose policy options that might strengthen the research Infrastructure In order to support such studies. We reviewed 23 published studies for drugs conducted between 1996 and 2004. Evaluation criteria included methodological characteristics, healthcare system characteristics, population characteristics, and applicability of results. Large variation in study quality was observed, particularly with study design, outcome data, treatment patterns and interpretation. Korean clinical data used was mostly from observational studies of 1-2 hospitals. Foreign data was extracted from clinical trials that did not Include Asian population and their selection criterion was not clarified. With respect to treatment patterns, medical records and hospital bills were used without adjustment regarding area, hospital type, and others. And next frequent situation relied on expert opinion from academic physicians in specialty practice. preference measures, when used, were not elicited from the Korean population. $78.3\%$ of studies did not clarify the funding source. If the Korean economic evaluation policy is to provide meaningful data for decision makers, the quality of cost-effectiveness studies will need to improve dramatically. This may involve access to or creation of better data, more diverse funding, unproved training of researchers and evaluators, and partnerships with technology manufacturers.

  • Purpose: Vaccine evaluation studies were initiated from 2000 by the Ministry of Food and Drug Safety to produce proper data about the safety and immunogenicity of vaccines. The purpose of this study was to review studies and reports on evaluation of vaccine such as immunogenicity, efficacy, effectiveness, safety and other related topics in order to find and analyze the data on the usefulness of each vaccine. Methods: From 2000 to 2014, the project "The vaccine evaluation" had been performed by several researchers, and studies and reports of vaccine evaluation. We reviewed the results and outcomes of studies regarding the evaluation of vaccine's usefulness and analyzed the possibilities of applying these data for establishing vaccine policies. For each vaccine, data analysis and organization were done according to evaluation fields. Results: A total of 83 studies were performed on vaccines from 2000 to 2014. For each vaccine, 8 studies were performed on BCG, 14 on DTaP/Td, 1 on poliovirus, 5 on Hib, 3 on pneumococcus, 11 on influenza, 3 on hepatitis A, 11 on MMR, 11 on varicella, and 16 on Japanese encephalitis. All studies were analyzed by the following evaluation area, such as safety, immunogenicity, seroprevalence, persistence of immunity, efficacy, effectiveness, vaccine evaluation methods, quality control product for vaccine, and others. Conclusions: Vaccine evaluation studies performed in Korea may be useful as references for establishing vaccination strategy and policy and could be used as baseline data for future studies on vaccine evaluation, vaccine policy establishment, and public/expert vaccine education in Korea.

  • This Paper examines analytic studies of the evaluation system used for evaluating government-supported R&D Institutes (GSRIs), and designs a new model for analyzing the evaluation system's effectiveness. The analytic models in existing studies use the meta evaluation and balanced scorecard (BSC) models. However, theses studies focused on the structure and elements of the evaluation system for examples, the appropriateness of the elements within the evaluation system and the balance of the evaluation index. Accordingly, the effectiveness of the GSRI evaluation system, that is, the evaluation's influence on GSRI performance improvement was not analyzed. This study uses the institution theory and contingency theory perspectives as related to government organization management to develop an analytical model of GSRI evaluation system effectiveness. The new model proposes an analytical approach for improving the effectiveness of the GSRI evaluation system in an institutionalized environment.

  • Purpose : This study aimed to present evidence by analyzing the characteristics and effectiveness of group art therapy interventions through an examination of domestic studies on group art therapy for older people with dementia. Methods : The database used DBpia, Riss, and Google Scholar, and the research period was from 2016 to November 2021. For the selected studies, the level of evidence was analyzed, bias evaluation was performed, and patient, intervention, comparison, and outcome were analyzed. For the evaluation of bias, the risk of bias assessment tool for non-randomized study (RoBANS) and Cochrane's risk of bias (RoB) were used. Results : As for the level of evidence of the included studies, level I consisted of five studies, and levels II and III each had one article. As a result of the bias evaluation of five studies through RoB, a "low risk of bias" was found for incomplete result data, selective result reporting, and others, except for four unclear evaluation areas. The "low risk of bias" ratio was 0~25 % in the evaluation of bias in two studies through RoBANS. For the evaluation tool, cognitive evaluation tool was used the most while mini-mental state examination-Korea was used the most frequently. For the intervention method, the most frequently used was group art therapy that employed recall in three studies, while collage, Korean painting, use of paper media, and procedural memory were used in each of the other studies. Each intervention was found to be significantly effective overall. Conclusion : This study provided clinical evidence by systematically reporting research on group art therapy for older people with dementia. In the future, it is necessary to check the effect of group art therapy on various areas other than cognition for older people with dementia. Moreover, the study should be conducted with the risk of bias sufficiently taken into consideration.

  • Vietnamese scholars contend that they have developed Southeast Asian studies viewing Southeast Asia as both a geographical entity with a long history and cultural tradition and a strategic region for modern development. This study has traced the construction of Southeast Asian studies as an academic discipline in Vietnam through the studies and arguments of Vietnamese scholars. It has put primary focus on the institutionalization of Southeast Asian studies, taking note of the assessment and perceptions of Vietnamese scholars. It also looked into the construction and limitations of Southeast Asian studies in Vietnam, which advocates Southeast Asian Studies as interdisciplinary area studies, with stressing of the origin of indigenous studies. The major contents of this study include: First, a historic overview of the institutionalization of Southeast Asian studies centering on research institutions of Southeast Asian studies in Vietnam, Second, the perceptions of Southeast Asian studies inside Vietnam and the inside evaluation of the effort to indigenize Southeast Asian studies. This study took note of Vietnamese scholars' perceptions and assessment of Southeast Asian studies performed by outsiders, primarily by Western scholars; the perceptions and evaluation of Southeast Asian studies conducted by Southeast Asian insiders; and the perceptions and evaluation of the origin of Southeast Asian studies indigenous to Vietnam. Last, it examined the construction and limitations of Southeast Asian studies in Vietnam, which advocates the studies as interdisciplinary regional studies.

  • Purpose: This study aims to systematically review the dual-task evaluation applied to the screening of mild cognitive impairment. It also aims to present various evaluation items and results analysis methods for dual tasks applied to patients with mild cognitive impairment. Methods: We conducted a systematic search of published studies in PubMed databases and KISS from January 2000 to August 2020 using the main keywords such as "Dual task," "Mild Cognitive impairment," "Elderly," and "Screening." We selected a total of 10 studies for the analysis from 1314 searched articles. Results: We analyzed the qualitative level of 10 studies that were nonrandomized two-group studies with evidence level II (100.0%). These results suggest that the evidence level of the studies was high. We analyzed 10 studies and identified 12 motor tasks and 19 cognitive tasks. Walking was the most commonly used evaluation motor task and counting backward by ones and naming animals were the most commonly used evaluation cognitive tasks. Moreover, the velocity speed was the most used result analysis method. The results indicate that there were significant differences in dual-task performance between patients with normal and mild cognitive impairment. Conclusion: The results of this study can be used as a basis for the selection of dual-task evaluation items and methods of analyzing the results for screening mild cognitive impairment. Furthermore, they are expected to be used for research on the development of dual-task evaluation tools. It is necessary to compare and analyze the usage trends of dual-task evaluation by cultural differences in future studies.

  • The purpose of this study is to suggest the shortcomings and the direction of the web accessibility evaluation studies by analyzing the research trends on web accessibility evaluation in Korea. For this aim, a total of 59 theses presented in the registered academic journal and the candidate of registration academic journals from January 2000 to March 2017 were selected. The selected dissertations have been analyzed based on the evaluators, the evaluation targets, the evaluation methods, and the evaluation results with regard to web accessibility. As a result of the analysis, the highest rate in the evaluator aspect was 'independent evaluation (66 percent)' and the highest percentage in the evaluation target aspect was 'web site (83 percent)'. When it came to the evaluation methods, automatic evaluation and the mixture of automatic evaluation and manual evaluation had a similar percentage. Lastly, only two papers showed that web accessibility did not have any problems. This study is meaningful in the sense that it suggested a desirable direction for the web accessibility studies in Korea and web accessibility evaluation studies in the situation when the meta studies which analyzed research trends are insufficient.
