  • Objective: Given the considerable disagreement between the Peer Assessment Rating (PAR) index and the American Board of Orthodontics Cast-Radiograph Evaluation, we aimed to develop a novel assessment system-the Improvement and Completion of Outcome (ICO) index-to evaluate the outcome of orthodontic treatment. Methods: Sixteen criteria from 4 major categories were established to represent the pretreatment malocclusion status, as well as the degree of improvement and level of completion of outcome during/after treatment: dental relationship (arch length discrepancy, irregularity, U1-SN, and IMPA); anteroposterior relationship (overjet, right and left molar position, ANB); vertical relationship (anterior overbite, anterior open-bite, lateral open-bite, SN-MP); and transverse relationship (dental midline discrepancy, chin point deviation, posterior cross-bite, occlusal plane cant). The score for each criterion was defined from 0 or -1 (worst) to 5 (ideal value or normal occlusion) in gradations of 1. The sum of the scores in each category indicates the area and extent of the problems. Improvement and completion percentages were estimated based on the pre- and post-treatment total scores and the maximum total score. If the completion percentage exceeded 80%, treatment outcome was considered successful. Results: Two cases, Class I malocclusion and skeletal Class III malocclusion, are presented to represent the assessment procedure using the ICO index. The difference in the level of improvement and completion of treatment outcome can be clearly explained by using 2 percentage values. Conclusions: Thus, the ICO index enables the evaluation of the quality of orthodontic treatment objectively and consecutively throughout the entire treatment process.

  • This study aimed to investigate health outcome of acute myocardial infarction (AMI) patients such as mortality and length of stay in hospital and to identify factors associated with the health outcome according to the comorbidity index. Nation-wide representative samples of 3,748 adult inpatients aged between 20-85 years with acute myocardial infarction were derived from the Korea National Hospital Discharge Injury Survey, 2005-2008. Comorbidity index was measured using the Charlson Comorbidity Index (CCI). The data were analyzed using t-test, ANOVA, multiple regression, logistic regression analysis in order to investigate the effect of comorbidity on health outcome. According to the study results, the factors associated with length of hospital stay of acute myocardial infarction patients were gender, insurance type, residential area scale, admission route, PCI perform, CABG perform, and CCI. The factors associated with mortality of acute myocardial infarction patients were age, admission route, PCI perform, and CCI. CCI with a higher length of hospital stay and mortality also increased significantly. This study demonstrated comorbidity risk adjustment for health outcome and presented important data for health care policy. In the future study, more detailed and adequate comorbidity measurement tool should be developed, so patients' severity can be adjusted accurately.

  • Since Research and Development has been expanded by government, It is very important to evaluate the outcome of Research and Development. Government have levied the penalty of researchers who misused research funding as time goes on. However, there is no protect law for the research before 2021. Government put new committee for the researchers to judge whether their action is legal or illegal based of Innovation Act 2021. Due to the various outcome index of research and development, many firms which is paticipating the research and development have been confused the outcome index. Also, It is difficult for government agencies for management to evaluate the outcome. Even if the committee is trying to solve dispute between researchers and the government agencies, it is not enough to solve it. Therefore, we need to consider Alternative Dispute Resolution(ADR), because the ADR has been developved detail skills for long time.

  • There are many objective indices of operative outcome of funnel chest, but there has been only a few report about the postoperative change of these indices and which is best correlated with subjective outcome. From January 1989 to December 1991, 74 patients with funnel chest underwent Ravitch operation and radiologic evaluation was performed on the twenty patients whose operative outcome were satisfactory by Humphreys` criteria and postoperative chest X-ray were available. Variable radiologic chest idices such as deformity grade [DG], lower vertebral index [LVI], upper vertebral index [UVI] and configuration index [CI] were measured preoperatively and 1, 6, 12 and 18 months pos-toperatively. The mean value of preoperative DG, LVI, UVI and CI were 5.32, 0.3, 0.26 and 1.01 respectively, and postoperative chages were as follows; DG; 3.13, 3.66, 3, 72, 4.0, LVI: 0.22, 0, 24, 0.25, 0.25 UVI; 0.27, 0.27, 0.27, 0.27 CI; 0.69, 0.77, 0.76, 0.79. The increments of CI were within the 90 percent confidence limit of normogram in most cases, but it was not true for LVI and UVI. And the differences between the observed and expected values of CI did not change significantly through the postoperative periods, which was not the case in LVI. We concluded from these results that 1] DG, LVI and CI were increased slowly during the postoperative follow up periods but the increments of CI were usually within the normal limits and so 2] CI can be used as a objective index of satisfactory outcome.

  • Objective : Psychological factors may have a major influence on the outcome of treatment for back pain. We investigated the relationship between the outcome and some psychological factors, such as self-reported pain intensity, disability, sleep disturbance and fatigue. Method : The study was conducted as a survey using a questionnaire and telephone interviews. The survey included consecutive 294 patients who visited the neurosurgical out-patient department complaining of low back pain and contacted by telephone on average seven months after the first visit. Pain intensity was measured by visual analog scale, and disability was assessed by Waddell's chronic disability index. Results : The outcome of treatment for back pain was recovered in 36.7%, improved in 30.6%, almost same in 28.6%, and aggravated in 4.1%. Overall rate of improvement was 67.3%. The rate of improvement was related to the duration, patterns and intensity of the symptom, and Waddell index. It was not influenced by the doctors, special studies, and methods of treatment. When the duration was more than 6 months, there were the symptoms of both back and legs, and the self-reported Waddell index was 1-3, the rate of improvement was relatively low. Although the intensity of the pain and disability was closely related to the degree of sleep disturbance, fatigue, appetite, or indigestion, the outcome of treatment for back pain was not always bad in patients with high psychological stress. Actually the outcome of the patients who complained severe pain and disability was better than the outcome of the others. Conclusion : The outcome of the back pain can be predicted by the duration, patterns and intensity of the symptom, and Waddell index. The multidisciplinary treatment will be necessary for the patients whose expected outcome is not good to reduce not only the physical symptoms but also the psychological stress.

  • 본 연구는 1984년부터 패널자료의 확보가 가능한 17개 OECD 국가를 표본으로 하여 R&D 생산성 및 효율성에 대한 실증분석을 통해 비교하고 우리나라의 수준과 특징을 살펴보고자 하였다. 이를 위해 그 성과를 산출(output) 측면과 성과(outcome) 측면으로 구분하고, 맘퀴스트 생산성지수와 자료포락분석방법을 활용하여 R&D경로단계별 생산성 및 효율성과 그 변화추이를 비교분석하였다. 우리나라는 R&D 투자 대비 산출 생산성은 매우 높은 반면, 평균효율성은 매우 낮게 나타났으며, 효율성의 시계열 변화추이를 보면 최초 지수 0.10에서 시작하여 최종 0.83까지 가파르게 상승하면서 주요 선진국들 수준에 도달하였다. R&D 산출 대비 생산성은 매우 낮으며, 통합 프런티어에 대한 효율성은 최초 지수 1.00에서 최종 0.057까지 주요 선진국들 수준으로 가파르게 하락하여 왔다. 그리고 상관분석을 통해 R&D 산출 대비 생산성이 곧 R&D 투자 대비 생산성을 가늠하는 지표가 될 수 있음을 보았다. 본 연구는 우리나라의 R&D 생산성 및 효율성 향상을 위해서는 R&D 투자 및 산출 증대의 노력이상으로 R&D 산출물의 활용 측면이 보다 강화되어야 하고 이를 위해 효과적인 기술확산 체계 구축, 기술금융시장환경 조성 및 사업화에 성공하기까지 실질적인 인큐베이팅 제공 등 전반적인 기술사업화 시스템의 혁신이 주요 과제임을 시사하고 있다.

  • Clinical research ultimately aimed to promptly diagnose and prevent diseases through precise biomarker development. Finding the optimal cut-off point of a regularly measured biomarker can help its interpretation and ultimately help in disease investigation and diagnosis, more specifically in determining the presence of diseases. Therefore, this study aimed to use the characteristics of outcome variables in clinical research to explain how to determine the optimal cutoff point. The outcome variables can be divided into dichotomous, ordinal, and survival types. The optimal cut-off point can be determined by finding points that maximize the Youden index, extended Youden index, and log-rank statistics. This study will enable clinical researchers to accurately determine the optimal cut-off points for regularly measured biomarkers, thereby enabling prompt disease diagnosis for effective treatment.

  • Multi-attribute risk assessments provide a useful framework for systematic quantitative risk assessment that the security manager can use to prioritize security requirements and threats. In the first step, the security managers identify the four significant outcome attributes(lost revenue, lost productivity, lost customer, and recovery cost). Next. the security manager estimates the frequency and severity(three points estimates for outcome attribute values) for each threat and rank the outcome attributes according to AHP(Analytic Hierarchy Process). Finally, we generate the threat index by using muiti-attribute function and make sensitivity analysis with simulation package(Crystal Ball). In this paper, we show how multi-attribute risk analysis techniques from the field of security risk management can be used by security managers to prioritize their organization's threats and their security requirements, eventually they can derive threat index. This threat index can help security managers to decide whether their security investment is consistent with the expected risks. In addition, sensitivity analysis allows the security manager to explore the estimates to understand how they affect the selection.

  • The survey was conducted to investigate several factors affecting the disease outcome with 116 infants aged 10 to 24 months residing in Kunsan city, Cheonbuk province . General characteristics, weaning practice , nutrient intake and the actual state for affecting disease were studied. Among many factors, mother's educational status was found to be the most influencing factor for affecting the disease outcome analyzed by oneway ANOVA. The exposure index disease, cold and diarrrhea, against mother's education were analyzed to find out the major factors for disease outcome. The education group up to middle school graduates, mother's job , nutrients supplements, feeding method, sex of baby were the factors, for the high school graduates, job , nutrients supplements were the causes, and the group graduated from the college the above grade mother's health state was the most important factor for the baby exposing to the disease. The disease outcome decreased when the bottle feeding was replaced by breast feeding, sufficient nutrients supplementation was recommended , and health care for mother during pregnancy was strongly advised.

  • 본 연구는 일과성허혈발작 및 급성뇌경색환자에서 양쪽 중 간대뇌동맥의 혈류속도 차이가 예후를 예측할 수 있는 지표가 될 수 있고, 이러한 예후예측력이 뇌졸중 아형 간에 차이가 있는 지를 관찰하는 것이다. 모든 대상자는 일과성허혈발작 및 급성뇌경색환자들이며, 기본적인 평가와 경두개도플러검사(TCD)가 실시되었다. 중간대뇌동맥 비대칭 지수(MCA asymmetry index)는 다음의 공식에 의해 구해졌다; MCA asymmetry index=(|RMCA MFV-LMCA MFV|/mean MCA MFV) ${\times}100$. 뇌경색 분류는 TOAST classification에 따라 진행되었다. 나쁜 예후(poor functional outcome)는 mRS score ${\geq}3$ at 3 months after stroke onset로 정의하였다. 총 988명의 급성뇌경색환자가 분석에 포함되었고, 그 중 157명(15.9%)이 나쁜 예후를 가지고 있었다. 뇌경색 하위유형 및 여러 혼란변수를 보정 후 실시한 다변량분석에서 중간대뇌동맥 비대칭 지수만 유일하게 독립적으로 나쁜 예후와 연관성을 보였다. ROC curve 분석에서 중간대뇌동맥 비대칭 지수를 예측모형에 투입하였을 때 투입 전에 비해 나쁜 예후를 예측하는 능력이 상승하는 것을 관찰하였다(from 88.6% [95% CI, 85.2-91.9] to 89.2% [95% CI, 85.9-92.5]). 급성뇌경색환자에서 중대뇌동맥 비대칭 지수는 나쁜 예후를 독립적으로 예측하였다. 따라서 경두개도플러검사는 급성뇌경색환자에서 나쁜 예후를 예측하는데 유용하게 사용될 수 있을 것이다.
