The study investigates the impact of data quality on the performance of artificial intelligence (AI). To this end, the impact of labeling error levels on the performance of artificial intelligence was compared and analyzed through simulation, taking into account the similarity of data features and the imbalance of class composition. As a result, data with high similarity between characteristic variables were found to be more sensitive to labeling accuracy than data with low similarity between characteristic variables. It was observed that artificial intelligence accuracy tended to decrease rapidly as class imbalance increased. This will serve as the fundamental data for evaluating the quality criteria and conducting related research on artificial intelligence learning data.

Objectives: In recent years, there has been an increased need for a way to extract desired information from multiple medical literatures at once. This study was conducted to confirm the usefulness of unstructured data analysis using previously published medical literatures to search for new indications. Methods: The new indications were searched through text mining, network analysis, and topic modeling analysis using 5,057 articles of atorvastatin, a treatment for hyperlipidemia, from 1990 to 2017. Results: The extracted keywords was 273. In the frequency of text mining and network analysis, the existing indications of atorvastatin were extracted in top level. The novel indications by Term Frequency-Inverse Document Frequency (TF-IDF) were atrial fibrillation, heart failure, breast cancer, rheumatoid arthritis, combined hyperlipidemia, arrhythmias, multiple sclerosis, non-alcoholic fatty liver disease, contrast-induced acute kidney injury and prostate cancer. Conclusions: Unstructured data analysis for discovering new indications from massive medical literature is expected to be used in drug repositioning industries.

Objectives: In this study, we strived to determine the possibility of socioeconomic welfare in oral healthcare by analyzing the National Health Insurance (NHI) coverage rate. To date, efforts to realize the "social economy" of healthcare are active. While oral disease is common and chronic among Koreans, the rate of NHI coverage of dental clinics is substantially lower than that of the medical clinics. Methods: We defined the NHI coverage of dental clinics as a proxy for "social skills" to improve oral health problems. The data were collected through a comparative analysis of the NHI coverage of dental clinics and that of non-dental clinics, in health welfare social cooperatives. Results: The NHI coverage rate of the dental clinics in health welfare social cooperatives ranged from 0.97 to 2.62 times that of the non-dental clinics in health welfare social cooperatives. Conclusions: In conclusion, responsible management is recommended for making health welfare social cooperatives meaningful as a social economy.

Objectives: It is a statistical analysis study to examine the results of CaPSPI (Diagnostic System for Climacteric and Postmenopausal Syndrome Pattern Identification), developed for objective defecation of climacteric and postmenopausal syndrome. Methods: Total 341 people's questionnaire responses were statistically analyzed. 275 people involved in developing CaPSPI 2018 (E) and 146 people involved in 2019-2020 study of research1,3). Results: The frequency of diagnosis for examination was the highest at liver depression, 93.8% for 320 times, the lowest at heartheat, 62.8% for 214 times. The frequency of treatment for examination was the highest at liver depression, 54.3% for 185 times, and the lowest at dual deficiency of heart-spleen, 16.7% for 57 times. The diagnosis ratio was the lowest at dual deficiency of heart-spleen, 19.72%, and the highest at liver depression, 57.81%. As a result of comparing these diagnoses with the Kupperman's index, all showed significant differences. As a result of comparing these disease elements, all showed significant differences. The correlation between diagnosis and dialectic elements was found to have similar results with the korean medical pathology, and in 7 dialectics except for heartheat, the treatment version was more severe or progressing to perjury than for examination. Conclusions: The CaPSPI shows the characteristics of korean medicine well, and it is needed to utilize the high correlative disease elements to upgrade the system.

Purposes: The objectives of this study present the direction of the criteria for the separately reimbursement of therapeutic medical device. Methodology: We summarized experts' opinion using Delphi survey and Analytic Hierarchy Process(AHP). 48 experts were gathered from Medical Insurance Review Nurses Association, medical device industry, academy and association, Medical Device Expert Evaluation Committee. Descriptive statistics, consistency index, content validity ratio were analyzed. Findings: Clinical utility, patient safety, infection control, cost-homogeneity, cost-effectiveness showed high feasibility and importance, but market contribution and functional utility showed low feasibility and importance in a relative sense. The results of functional utility differed between clinical and non-clinical experts. Measurability was low across the whole area. Among the criteria for the separately reimbursement of therapeutic medical device. Patient safety/infection control and clinical utility showed the highest relative importance values, analyzed using AHP. Practical Implications: Patient safety and infection control are needed to be considered as one of Value Assessment Criteria. It is important to find out how to improve the measurability of therapeutic medical device.

This study is to examine the impact of sales franchisor's relationship-oriented efforts(flexibility, problem solving support, customization, information exchange, and supervisor characteristics) on relationship quality(satisfaction, trust, and commitment) and recontract intentions. In order to analyze proposed model, this study collected the 233 franchisees with owner or hired manager. The data were analyzed with SPSS/PC 18.0 and AMOS 18.0. First, to test unidimensionality and nomological validity of the measures of each construct we employed a scale refinement procedure. The result of reliability test with confirmatory factor analysis warranted unidimensionality of the measures for each construct. The findings are as follows: First, relationship-oriented efforts had positive effects on relationship quality (satisfaction, trust, and commitment) of franchisee. Second, satisfaction had positive effect on trust, but did not on recontract intentions. Third, trust had positive effects on commitment and recontract intentions, respectively. Finally, commitment had a positive effect on recontract intentions. At the end of this paper, managerial implications and limitations and future research directions were suggested.

In order to deduce the pathogenic factor(PF) diagnosis logic of underlying in pattern identification of Korean medicine, 2,072 cases of DSOM(Diagnosis System of Oriental Medicine) data from May 2005 to April 2022 were collected and analyzed by means of decision tree model(DTM). The entire data were divided into training data and validation data at a ratio of 7:3. The CHAID algorithm was used for analysis of DTM, and then validity was tested by applying the validation data. The decision rules of items and pathways determined from the diagnosis data of Qi Deficiency, Blood Deficiency, Yin Deficiency and Yang Deficiency Pathogenic Factor of DSOM were as follows. Qi Deficiency PF had 7 decision rules and used 5 questions: Q124, Q116a, Q119, Q119a, Q55. The primary indicators(PI) were 'lack of energy' and 'weary of talking'. Blood deficiency PF had 7 decision rules and used 6 questions: Q113, Q84, Q85, Q114, Q129, Q130. The PI were 'numbness in the limbs', 'dizziness when standing up', and 'frequent cramps'. Yin deficiency PF had 3 decision rules and used 2 questions: Q144 and Q56. The PI were 'subjective heat sensation from the afternoon to night' and 'heat sensation in the limbs'. Yang deficiency PF had 3 decision rules and used 3 questions: Q55, Q10, and Q102. The PI were 'sweating even with small movements' and 'lack of energy'. Conclusively, these rules and symptom information to decide the Qi·Blood·Yin·Yang Deficiency PF would be helpful for Korean medicine diagnostics.
