소프트웨어 개발 환경이 빠르게 변화함에 따라 시스템의 복잡성이 증가하고 있다. 이에 따라 크고 작은 소프트웨어의 버그를 피할 수 없게 되며 이를 효율적으로 처리하기 위해 Bug report 를 사용한다. 하지만, Bug report 에서 개발자가 해당 Bug report 의 우선순위를 결정하는 과정은 노력과 비용 그리고 시간을 많이 소모하게 만든다. 따라서, 본 논문에서는 Bug report 내의 Stack trace 를 기반으로 Bug 의 우선순위를 자동적으로 추천하는 기법을 제안한다. 이를 위해 본 연구에서는 첫 번째로 Bug report 로부터 Stack trace 를 추출하였으며 Stack trace 의 3 가지 요소(Exception, Reason 그리고 Stack frame)에 TF-IDF, Word2Vec 그리고 Stack overflow 를 사용하여 특징 벡터를 정의하였다. 그리고 Bug 의 우선순위 추천 모델을 생성하기 위해 4 가지의 Classification 알고리즘을(Random Forest, Decision Tree, XGBoost, SVM)을 적용하였다. 평가에서는 266,292 개의 JDK library 의 Bug report 데이터를 수집하였고 그중 Stack trace 를 가진 Bug report 로부터 68%의 정확도를 산출하였다.

The purpose of this study is to develop an environmental report for children and to examine the learning effects of the environmental report on elementary school students. This study is carried out by the survey. The results of this study are as follows. First, the Environmental Report for children, which consists of 8 subjects related to the environmental policy in Korea. 1) Green Growth and Sustainable Policy, 2) Climate Change, 3) Water Supply and Sewage Policy, 4) Sustainable Watershed Management, 5) Conservation of Biodiversity, 6) Resource Recirculation, 7) Environmental Health for Children, and 8) Environmental Dictionary, was systematically developed. Second, the Environmental report developed was examined the effects to third and fourth grade elementary school students in Incheon and Daegu. By dividing elementary school students into two groups: A Control group and an Experimental group, the lessons were respectively executed. In conclusion, the Environmental Report leads to good effects when it is applied to both Environmental Education and the public relation of the Environmental Policy in Korea. Finally, it would be expected to be efficient in learning Sustainable Development and the Environmental Policy.

Purpose: We aimed to identify the awareness and reporting obligation attitude toward child abuse among paramedic students who will become paramedics in the future and play an important role as those with an obligation to report child abuse. Methods: Data were collected from the paramedic students after consent to this study through online. The period of data collection was from July 10 to August 2, 2023 and 142 questionnaires were analyzed using SPSS 27.0 program. Results: 79.6% of the subjects knew who was required to report child abuse, but only 46.5% knew the reporting agency, and 30.3% knew the reporting procedure. Additionally, 83.8% were willing to report child abuse when discovered. Awareness of child abuse was 4.58±0.29 points out of 5. The reporting obligation attitude toward child abuse was 3.53±0.74 out of 5. Awareness of child abuse was determined by whether one was required to report child abuse (p<.05), whether one was aware of the reporting procedure (p<.05), and whether one was willing to report child abuse (p<.05), there appeared to be a significant difference. Attitude toward reporting obligation regarding child abuse was determined by gender (p<.05), whether one was aware of the obligation to report child abuse (p<.05), and willingness to report upon discovery of child abuse (p<.01), it was found that there was a significant difference. Conclusion: It is necessary to develop realistic educational content that can be linked to suspected abuse sites in hospitals and out of hospitals so that students who will become paramedics in the future can play an active role as mandatory reporters of child abuse.

Introduction The case report provides pivotal basis for clinical research and education, however systematically organized guideline for reporting case report was not properly applied and it tackled the development of traditional medicine in Korea. The purpose of this study was to implement guideline for reporting CAse REport(CARE guideline) incorporating unique characteristics of Sasang medicine with the help of examples and explanations. Methods and Results The guideline for reporting CAse REport for Sasang medicine(CARES guideline) including diagnosis of traditional medicine and treatment with acupuncture and medical herbs was suggested, and practical examples explaining details of each CARES items were provided. Discussion and Conclusion This study would provide foundation for consensus-based and common CARE guideline for traditional Korean medicine. And, the CARES guideline would provide clinical platform for developing refined Sasang type differentiation technique using reported biopsychosocial and clinical type-specific features and realistic cases for Problem Based Learning courses as evidence-based education.

Background : A report published by the National Institute of Toxicological Research (NITR) in January 2004 about toxic hepatitis in Korea contained the result of analysis on 55 cases of severe toxic hepatitis from 7 university hospitals for 8 months. NITR claimed that the extrapolated annual frequency of severe toxic hepatitis in Korea was 1904 cases per year. They also claimed that the most frequent etiology of severe toxic hepatitis were herbal medications and similar plant preparations (61.7%), contrasted with traditional therapeutic preparations and healthy foods (29.1%). I have investigated that report to be certain of the result because it is a very important subject for public health and society in Korea. Results : The NITR report has too many problems to have faith in its results. They include the following: 1. The report uses only 55 cases to estimate annual prevalence rate of severe toxic hepatitis in Korea. 2. There was a large regional preponderancy in the NITR report (2 cases in Seoul from a population of 10.17 million, 19 cases in Gwangju from a population of 1.4 million) 3. There was another preponderancy that selected much fewer cases caused by western medication (9.1%) than other reasons. 4. The NITR report used a modified scale than that officially recognized to diagnose toxic hepatitis. 5. There was a mistake using the scale to adapt the right indications. 6. They collected cases before beginning the study, although it was a prospective study. There was also not any questionnaire or other materials concerned with alcohol, drugs, or history of past liver disease. Conclusions : NITR is one of the important official arms of the government of Korea. Nevertheless, there is a severe problem in validity because of selection bias, uncertain accuracy, and insufficiency of raw materials in the report. Therefore it seems incorrect to generalize the results of the report and there is a lack of confidence in it as a national study publishing by the NITR.

Tracheo-innominate artery fistula (TIF) is a rare, life-threatening complication of tracheostomy that makes it difficult to secure the airway due to massive bleeding, constituting a medical emergency. Therefore, most successful surgical treatments include innominate artery debridement and tracheal fistula repair. Herein, we report a case of successful surgical treatment of a TIF while maintaining cerebral blood flow through an artificial vascular graft.

Report documents of industrial and occupational accidents have continuously been accumulated in private and public institutes. Amongst others, information on narrative-texts of accidents such as accident processes and risk factors contained in disaster report documents is gaining the useful value for accident analysis. Despite this increasingly potential value of analysis of text information, scientific and algorithmic text analytics for safety management has not been carried out yet. Thus, this study aims to develop data processing and visualization techniques that provide a systematic and structural view of text information contained in a disaster report document so that safety managers can effectively analyze accident risk factors. To this end, the risk factor map using text mining and self-organizing map is developed. Text mining is firstly used to extract risk keywords from disaster report documents and then, the Self-Organizing Map (SOM) algorithm is conducted to visualize the risk factor map based on the similarity of disaster report documents. As a result, it is expected that fruitful text information buried in a myriad of disaster report documents is analyzed, providing risk factors to safety managers.
