  • With the help of learning analytics, MOOCs have wider potential to succeed in learning through promoting self-regulated learning (SRL). The current study aims to apply and validate visualization design guidelines for a MOOC dashboard to enhance such SRL capabilities based on learning analytics. To achieve the research objective, a MOOC dashboard prototype, LM-Dashboard, was designed and developed, reflecting the visualization design guidelines to promote SRL. Then, both expert and learner participants evaluated LM-Dashboard through iterations to validate the visualization design guidelines and perceived SRL effectiveness. The results of expert and learner evaluations indicated that most of the visualization design guidelines on LM-Dashboard were valid and some perceived SRL aspects such as monitoring a student's learning progress and assessing their achievements with time management were beneficial. However, some features on LM-Dashboard should be improved to enhance SRL aspects related to achieving their learning goals with persistence. The findings suggest that it is necessary to offer appropriate feedback or tips as well as to visualize learner behaviors and activities in an intuitive and efficient way for the successful cycle of SRL. Consequently, this study contributes to establishing a basis for the visual design of a MOOC dashboard for optimizing each learner's SRL.

  • Purpose: While regurgitation is a common and often benign phenomenon in infants and younger children, it can also be a presenting symptom of gastroesophageal reflux disease (GERD). If untreated, GERD can lead to dangerous or lifelong complications. Clinical practice guidelines (CPGs) have been published to inform clinical diagnosis and management of pediatric GERD, but to date there has been no comprehensive review of guideline quality or methodological rigor. Methods: A systematic literature search was performed, and a total of eight CPGs pertaining to pediatric GERD were identified. These CPGs were evaluated using the Appraisal of Guidelines for Research and Evaluation instrument. Results: Three CPGs were found to be "high" quality, with 5 of 6 domains scoring >60%, one "average" quality, with 4 of 6 domains meeting that threshold, and the remaining four "low" quality. Conclusion: Areas of strength among the CPGs included "Scope and Purpose" and "Clarity and Presentation," as they tended to be well-written and easily understood. Areas in need of improvement were "Stakeholder Involvement," "Rigor of Development," and "Applicability," suggesting these CPGs may not be appropriate for all patients or providers. This analysis found that while strong CPGs pertaining to the diagnosis and treatment of pediatric GERD exist, many published guidelines lack methodological rigor and broad applicability.

  • The purpose of this study is to propose a guideline to help the client and bidder operate the BIM project in the domestic road field. As BIM design is mandatory in the construction field, documents disclosed by the ordering agency must essentially include procedures and step-by-step requirements to support BIM. The purpose of this study is to propose the structure and components of the guidelines that practitioners need practically by utilizing the currently announced road field guidelines. The guidelines are analyzed based on the procurement documents that were pre-emptively shared overseas, and supplemented according to the domestic situation. Furthermore, the effectiveness of the revised guidelines is confirmed through expert consultation. This study aims to contribute to creating an environment in which construction practitioners who have no experience in BIM project can efficiently carry out BIM projects.

  • Despite all efforts to reduce construction disaster, construction site accident rate has steadily increased in Korea since 2008. As a different approach from traditional research, there is a growing issue about design for safety concept to prevent construction disaster. The notion is that construction worker's safety need to be considered at design phase, not only at construction phase. Globally, the notion has been noted that to improve the safety of the worker and used in practice. However, in Korea, most of safety management guidelines are limited to construction phase. From recent statistics, only 1.4 percent of designer feel responsible for safety accident at construction site. In this circumstance, this research find out safety guidelines through literatures reviews and practical experience of safety management in other country which apply design for safety concept. Selected guidelines are verified by survey which is evaluated with risk, function, cost, time and aesthetic view categories. Through the survey, define guidelines which could be effectively applied in Korea. By using proposed safety guidelines for design phase, preventing construction accident and improving designer's recognition of safety issue at design phase are expected.

  • Hepatocellular carcinoma (HCC) can be noninvasively diagnosed on the basis of its characteristic imaging findings of arterial phase enhancement and portal/delayed "washout" on computed tomography (CT) and magnetic resonance imaging (MRI) in cirrhotic patients. However, different specific diagnostic criteria have been proposed by several countries and major academic societies. In 2018, major guideline updates were proposed by the Association for the Study of Liver Diseases, European Association for the Study of the Liver (EASL), Korean Liver Cancer Association and National Cancer Center (KLCA-NCC) of Korea. In addition to dynamic CT and MRI using extracellular contrast media, these new guidelines now include magnetic resonance imaging (MRI) using hepatobiliary contrast media as the first-line diagnostic test, while the KLCA-NCC and EASL guidelines also include contrast-enhanced ultrasound (CEUS) as the second-line diagnostic test. Therefore, hepatobiliary MR contrast media and CEUS will be increasingly used for the noninvasive diagnosis and staging of HCC. In this review, we discuss the emerging role of hepatobiliary phase MRI and CEUS for the diagnosis of HCC and also review the changes in the HCC diagnostic criteria in major guidelines, including the KLCA-NCC practice guidelines version 2018. In addition, we aimed to pay particular attention to some remaining issues in the noninvasive diagnosis of HCC.

  • An appropriate post-polypectomy surveillance program requires the effectiveness of reducing colorectal cancer and safety. In addition, the post-polypectomy surveillance program should consider the burden of limited medical resource capacity, cost-effectiveness, and patient adherence. In this sense, a risk-stratified surveillance program based on baseline colonoscopy results is ideal. Major international guidelines for post-polypectomy surveillance, such as those from the European Union and the United States, have recommended risk-stratified surveillance programs. Both guidelines have recently been updated to better differentiate between high- and low-risk individuals. In both updated guidelines, more individuals have been downgraded to lower-risk groups that require less frequent or no surveillance. Furthermore, increased attention has been paid to the surveillance of patients who undergo serrated polyp removal. Previous guidelines in Japan did not clearly outline the risk stratification in post-polypectomy surveillance. However, the new colonoscopy screening and surveillance guidelines presented by the Japan Gastroenterological Endoscopy Society include a risk-stratified post-polectomy surveillance program. Further discussion and analysis of unresolved issues in this field, such as the optimal follow-up after the first surveillance, the upper age limit for surveillance, and the ideal method for improving adherence to surveillance guidelines, are warranted.

  • 본 연구는 경관법 제정 이후 경관법에 의한 경관계획 관련지침과 경관계획의 내용을 분석하여 경관계획 진행사항과 문제점을 파악하고, 이에 대한 개선방안을 제안하고자 하였다. 경관계획의 특정을 살펴보기 위해 경관계획 수립 시 기초가 되는 경관계획수립지침과 경관계획보고서를 비교 분석하였다. 경관계획수립지침 분석은 실제 경관계획을 수립한 전문가를 대상으로 설문조사를 실시하였으며, 중요도-성취도 분석기법을 활용하여 각 단계별 지침 내용의 유효성과 현실적용 정도 등을 분석하였다. 경관계획보고서 분석은 법정계획으로 기본경관계획이 이미 수립된 자치단체 중 광역시, 시, 군별로 각 2곳을 선정하여 총 6개의 경관계획 보고서를 경관계획수립지침을 기준으로 분석하였다. 본 연구의 결과는 다음과 같다. 경관자원조사 및 분석단계는 가장 체계화된 틀로 진행되고 있었으나, 지나치게 세분화되어 실제 경관계획 시 도움이 되지 못하고 있는 부분이 있었다. 반면, 경관구조분석은 경관구조분석에 대한 다양한 접근방법과 기법 등의 구체적 방안 제시가 필요한 것으로 파악되었다. 경관기본구상단계는 기존의 현황조사 결과와 상위계획 등을 반영하여 지역특성에 맞는 지자체 아이엔티티의 확립이 필요하며, 경관계획수립지침에서도 보다 구체적인 지침이 필요한 것으로 파악되었다. 경관기본계획단계는 지자체 간의 수준의 차이가 가장 큰 것으로 나타나서, 경관계획수립지침에서 계획 내용에 대한 구체적인 지침이 필요한 것으로 보인다. 경관계획수립지침 상 경관자원조사 및 분석단계에서는 '경관자원조사 종합 및 과제도출'과 기본경관계획단계의 '조망점 계획'이 추가되는 것이 필요한 것으로 판단된다.

  • Objectives: This study aimed to learn what should be considered in the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD) by analyzing the existing guidelines and clinical trials.Methods: The development committee searched the existing guidelines for herbal medicinal products or GERD. Then, clinical trials related to GERD using herbal medicine were selected. The chosen trials were analyzed in terms of their inclusion and exclusion of participants, intervention, comparators, outcome, and trial design. Then, we compared the results of the analysis according to the regulations and guidelines of the Ministry of Food and Drug Safety to suggest the issues that we will have to consider when developing the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD).Results: As a result, few guidelines for GERD and clinical trials with herbal medicinal products were located in the national institution homepage. In addition, 8 articles were found using the following combination of search terms: “Gastroesophageal reflux disease”, “GERD”, “herbal medicine”, “herbal therapy”, “Korean Medicine”, “Traditional Chinese Medicine”, and “TCM”. Even though all trials had their own unique research questions, all studies were performed using a randomization method. Most trials included participants with reflux esophagitis, but two trials targeted proton pump inhibitor-refractory GERD. The type of intervention varied, such as decoction, granules, and capsules. Additionally, individualized herbal medicines were used in two studies. Comparators were diverse, such as placebo, Western medicine, and electro-acupuncture. The most frequently used outcome for efficacy was the effectiveness rate. In addition, the outcome for evaluating quality of life, esophageal mucosa and pressure, esophageal acid reflux, and recurrence rates were used. Safety was investigated by recording adverse events and carrying out laboratory tests.Conclusions: We identified some issues by reviewing the existing guidelines and comparing them with clinical trials for GERD and herbal medicinal products. These results will be utilized for developing the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD).
