Inappropriate antibiotic use significantly contributes to antibiotic resistance, resulting in reduced antibiotic efficacy and an increased burden of disease. The objective of this study was to investigate the characteristics of prescribers whose antibiotics use was high and to explore factors affecting the use of antibiotics by medical institutions. This study analyzed the National Health Insurance claims data from 2015. Antibiotic prescription data were analyzed in terms of the number of defined daily doses per 1,000 patients per day, according to the World Health Organization anatomical-therapeutic-chemical classification and methodologies for measuring the defined daily dose. We investigated the characteristics of prescribers and medical institutions with high antibiotic use. Multivariate regression analyses were performed on the basis of characteristics of the medical institution (number of patients, type of medical institution [hospital or clinic], age of the physician, etc.). The number of patients and number of beds were found to be significant factors affecting antibiotic use in hospitals, and the number of patients, region, and medical department were significant factors affecting antibiotic use at the level of medical institutions. These findings are expected to help policy-makers to better target future interventions to promote prudent antibiotic prescription.

This paper presents a critical analysis of the current application of big data in higher education and how Learning Analytics (LA), and Educational Data Mining (EDM) are helping to shape learning in higher education institutions that have applied the concepts successfully. An extensive literature review of Learning Analytics, Educational Data Mining, Learning Management Systems, Informal Learning and Online Social Networks are presented to understand their usage and trends in higher education pedagogy taking advantage of 21st century educational technologies and platforms. The roles of and benefits of these technologies in teaching and learning are critically examined. Imperatively, this study provides vital information for education stakeholders on the significance of establishing a teaching and learning agenda that takes advantage of today's educational relevant technologies to promote teaching and learning while also acknowledging the difficulties of 21st-century learning. Aside from the roles and benefits of these technologies, the review highlights major challenges and research needs apparent in the use and application of these technologies. It appears that there is lack of research understanding in the challenges and utilization of data effectively for learning analytics, despite the massive educational data generated by high institutions. Also due to the growing importance of LA, there appears to be a serious lack of academic research that explore the application and impact of LA in high institution, especially in the context of informal online social network learning. In addition, high institution managers seem not to understand the emerging trends of LA which could be useful in the running of higher education. Though LA is viewed as a complex and expensive technology that will culturally change the future of high institution, the question that comes to mind is whether the use of LA in relation to informal learning in online social network is really what is expected? A study to analyze and evaluate the elements that influence high usage of OSN is also needed in the African context. It is high time African Universities paid attention to the application and use of these technologies to create a simplified learning approach occasioned by the use of these technologies.

Ever since its introduction in the 1927 ICC Arbitration Rules, scrutiny of awards by the ICC Court has been a cornerstone feature of ICC arbitration. Most players involved in the arbitral process are likely to concede that a certain level of review of arbitral awards is both desirable and beneficial. Indeed, proponents among the users are frequently influenced in their choice of the ICC as the administering arbitral institution, based on their strong conviction that time and money invested in the resolution of a dispute is ultimately only well spent if awards are voluntarily complied with or at least less susceptible to be set aside. By providing a look behind the scenes of the scrutiny process, the article does away with tales of excessive intervention on behalf of the arbitral institution when reviewing and approving awards and demystifies the role played by the ICC Court throughout its close interaction with arbitral tribunals operating under the ICC Rules. The article further argues that the scrutiny process can be a highly efficient tool that helps to increase the quality and enforceability of awards rendered under the aegis of the ICC.

The purpose of this study is to estimate cesarean section rate in Korea and analyze characteristics of health care institution which affect regional variation in the rate. We have searched vaginal and cesarean section deliveries among Diagnosis Related Group dat based upon insurance claim bills which have been submitted to Korean Insurance Corporation for two years since March, 1985. The results are as follows: 1. Out of all delivery cases of 87,500, cesarean section rate was 16.3% (14,299 cases). 2. Cesarean section rate varied according to size and ownership of health care institutions. In above 6- bed sized hospitals, the rate was at about 20% higher than small sized institutions, but rather in hospitals that have more than 500 beds, it was somewhat low. Classified by the hospital ownership, the rate was low at 18.4% in hospitals of religious organization and highest at private or corporate hospitals. 3. This study shows large regional variation in cesarean section rate; there are two times differences between region with the highest and lowest rate. Strongly related factors in that variation was the ownership of health care institution and urbanization variables. Low level of cesarean section rate in a region is explained by high proportion of delivery cases at institutions of religious organization and at insitutions in county level site. This result shows that apart from medical conditions of patients, indications of cesarean section differs from health care providers, and especially ownership of institution strongly affect them. Cesarean section rate in Korea is supposed to be at high level and development of utilization review programs to keep appropriate cesarean section rate is needed.

Purpose: The purpose of this study is to assess the status of the Human research Protection Program (HRPP) within a hospital or a research institute in Korea. Methods: Survey was conducted during June 12th-21th 2019. Survey was distributed to the members of Korean Association of IRB (KAIRB) through each IRB office. Descriptive statistics were performed using SPSS ver. 26. Results: A total of 86 people responded, and 75 (87.0%) answered that they have perceived the HRPP. Seventy out of 86 respondents (81.4%) were conducting internal audit, several institutions were operated simultaneously the other form of audits such as IRB audit, system audit. Regarding the management of Suspected Unexpected Serious Adverse Reaction (SUSAR), 62.8% answered that they have regulation that can decide to suspend the study when there is a risk to subject safety. Among the respondents, 66.3% performed 'Help desk.' Conclusion: In this study, we assessed the current status of HRPP operation at each research institution based on Ministry of Food and Drug Safety (MFDS) HRPP guidelines. The HRPP accredited institution operated the subject protection activities according to this program, and even if the HRPP was not officially operated, the related activities were conducted focusing on the cases that could have a significant impact on the safety of research subjects. In order to ensure the quality of domestic clinical trials and to stably establish the HRPP, efforts at the individual institution level will be required.

Objective : This study aims to understand the consumer's needs for Korean medicine medical service using online review analysis of medical consumers. Methods : We analyzed the purpose and satisfaction factors of medical service use using LDA (Latent Dirichlet Allocation) topic modeling. The data used in the study was 120,727 screened reviews written by medical consumers registered on Naver. The analyzed results were compared with the "2020 Korean Medicine Utilization Survey". Results : From 2018 to 2021, the five most frequently used terms were "kindness", "treatment", "doctor", "Korean medicine", and "acupuncture". The main purpose of visiting Korean medicine medical clinic and hospital was to treat "traffic accidents" in 2018, "waist(back) pain" in 2019, "musculoskeletal pain" in 2020 & 2021. Based on the rating, reviewers were satisfied with "explanation of treatment" and "treatment attitude", and dissatisfied with "accessibility to the institution". Conclusion : We concluded that the main purpose of use of Korean medicine institution was to treat musculoskeletal disorders. Based on the results of this study, it is expected that it will be used to improve Korean medicine medical service in the future.

Purpose: Traumatic pancreatic injury is not common in abdominal trauma injury. However, the morbidity and the mortality rates of patients with pancreatic injury, which are related with difficulties of initial assessment, establishment of diagnosis, and treatment are relatively high. The aim of this study is to review our institution's experience and suggest a diagnosis and therapeutic algorithm for use in cases involving traumatic pancreatic injury. Methods: Eighteen(18) patients with blunt pancreatic injury from January, 2004 to October 2012 were included in this study. We analyzed treatment and diagnosis method, other organ injury, treatment interval, hospital stay and complications retrospectively. Results: Nine patients were treated with conservative medication and another nine patients were treated surgically. Complications occurred in nine patients, and one patient died due to intraventricular hemorrhage and subdural hemorrhage with multiple organ failure. Delayed surgery was performed in three cases. The early and delayed surgery groups showed difference in hospital stay and intensive care unit stay. Delayed surgery was associated with a longer hospital stay (p=0.007) than immediate surgery. Conclusion: In blunt pancreatic trauma, proper early diagnosis and prompt treatment are recommended necessity. Based on this review of our experience, we also suggest the adoption of our institution's algorithm for cases involving traumatic pancreatic injury.

Objectives: Several practice guidelines recommended both medication and behavior modification to control hypertension. The objective of this study was to analyze ambulatory care utilization pattern and related factors. Methods: A retrospective cohort study was conducted among 45,267 new users who initiated treatment with hypertensive drugs in 2003. Korean National Health Insurance Claims Data was used to study the medical care utilization behavior and related factors after treatment initiation for up to four years. Taking prescription was considered as medical care utilization. Results: More than 20% of patients discontinued visiting physicians for prescription after initiating antihypertensive drug therapy. The average number of institutions visited by patients was about 1.3 annually. Clinic was the most frequently visited institution by patients. In GEE analysis, probability of continuous visit one institution after initiating antihypertensive drug treatment increased in patients who were women, old, have comorbidity, visited clinic or hospital mainly in previous year. Conclusions: Young hypertensive male patients who have no major comorbidity showed high possibility to discontinue medical service utilization. It is necessary to educate these targeted patients about importance of hypertension management in early stage after treatment initiation.

Background: Gestational trophoblastic neoplasia (GTN) is a spectrum of disease with abnormal trophoblastic proliferation. Treatment is based on FIGO stage and WHO risk factor scores. Patients whose score is 12 or more are considered as at extremely high risk with a high likelihood of resistance to first line treatment. Optimal therapy is therefore controversial. Objective: This study was conducted in order to summarize the regimen used for extremely high risk or resistant GTN patients in our institution the in past 10 years. Materials and Methods: All the charts of GTN patients classified as extremely high risk, recurrent or resistant during 1 January 2002 to 31 December 2011 were reviewed. Criteria for diagnosis of GTN were also assessed to confirm the diagnosis. FIGO stage and WHO risk prognostic score were also re-calculated to ensure the accuracy of the information. Patient characteristics were reviewed in the aspects of age, weight, height, BMI, presenting symptoms, metastatic area, lesions, FIGO stage, WHO risk factor score, serum hCG level, treatment regimen, adjuvant treatments, side effects and response to treatment, including disease free survival. Results: Eight patients meeting the criteria of extremely high risk or resistant GTN were included in this review. Mean age was 33.6 years (SD=13.5, range 17-53). Of the total, 3 were stage III (37.5%) and 5 were stage IV (62.5%). Mean duration from previous pregnancies to GTN was 17.6 months (SD 9.9). Mean serum hCG level was 864,589 mIU/ml (SD 98,151). Presenting symptoms of the patients were various such as hemoptysis, abdominal pain, headache, heavy vaginal bleeding and stroke. The most commonly used first line chemotherapeutic regimen in our institution was the VAC regimen which was given to 4 of 8 patients in this study. The most common second line chemotherapy was EMACO. Adjuvant radiation was given to most of the patients who had brain metastasis. Most of the patients have to delay chemotherapy for 1-2 weeks due to grade 2-3 leukopenia and require G-CSF to rescue from neutropenia. Five form 8 patients were still survived. Mean of disease free survival was 20.4 months. Two patients died of the disease, while another one patient died from sepsis of pressure sore wound. None of surviving patients developed recurrence of disease after complete treatment. Conclusions: In extremely high risk GTN patients, main treatment is multi-agent chemotherapy. In our institution, we usually use VAC as a first line treatment of high risk GTN, but since resistance is quite common, this may not suitable for extremely high risk GTN patients. The most commonly used second line multi-agent chemotherapy in our institution is EMA-CO. Adjuvant brain radiation was administered to most of the patients with brain metastasis in our institution. The survival rate is comparable to previous reviews. Our treatment demonstrated differences from other institutions but the survival is comparable. The limitation of this review is the number of cases is small due to rarity of the disease. Further trials or multicenter analyses may be considered.
