Bug report processing is a key element of bug fixing in modern software maintenance. Bug reports are not processed immediately after submission and involve several processes such as bug report deduplication and bug report triage before bug fixing is initiated; however, this method of bug fixing is very inefficient because all these processes are performed manually. Software engineers have persistently highlighted the need to automate these processes, and as a result, many automation techniques have been proposed for bug report processing; however, the accuracy of the existing methods is not satisfactory. Therefore, this study focuses on surveying to improve the accuracy of existing techniques for bug report processing. Reviews of each method proposed in this study consist of a description, used techniques, experiments, and comparison results. The results of this study indicate that research in the field of bug deduplication still lacks and therefore requires numerous studies that integrate clustering and natural language processing. This study further indicates that although all studies in the field of triage are based on machine learning, results of studies on deep learning are still insufficient.

It is challenging work to predict weather and climate conditions of the future in advance. Since ENIAC was developed, weather and climate research areas have been taking advantage of the improvements in computer hardware. High performance computers allows researchers to build high quality models that allow them to make good predictions of what might happen in the future. Statistics on the high performance computers are one of the major interest to not only manufacturers but also the users such as weather and climate researchers. For this reason, the Top500 Supercomputer Sites Report has been being released twice a year since 1993 to provide a reliable basis for tracking and detecting trends in high performance computing. Using the Top500 Report, a short review on the supercomputer trends in weather and climate research areas is provided in this article.

This report presents a rare case of ameloblastoma with histopathologic and radiographic calcification, including 3-dimensional cone-beam computed tomographic (CBCT) images. A 22-year-old woman had hard swelling on the right mandible. Panoramic and CBCT images showed multilocular radiolucencies with internal calcification foci in the right mandible. Three-dimensional images clearly showed varying-sized radiopacities within the lesion from various angles. A histopathologic examination showed central squamous differentiation and more densely packed peripheral palisading ameloblastic cells. Many areas of keratin pearls and calcifications were also seen. Four previous reports have described 5 cases of ameloblastoma showing histopathologic calcification. This might be the first report to present the calcification of ameloblastoma on panoramic and CBCT images, especially on 3-dimensional images.

Several modalities that have been used in Korean medicine have not undergone evaluation. The Korea Institute of Oriental Medicine (KIOM), a South Korean national research agency, launched the Korean medicine case Report (KORE) program in May 2019 to promote case reports, especially among clinicians. The aim was to (1) introduce the KIOM-initiated KORE program, (2) report the results from the KORE program, and (3) present the challenges and limitation from the KORE program. We conducted a narrative review of the cases to which KORE was applied. A total of 16 proposals were reviewed since May 2019. Five proposals were rejected, and 7 case reports were included. Case reports for 3 therapies have been created under guidance. The KORE program makes it easier for Korean medicine doctors to initiate and complete case reports.

Recent advances in artificial intelligence have allowed for easier sentiment analysis (e.g. positive or negative forecast) of documents such as a finance reports. In this paper, we investigate a method to apply text mining techniques to extract in the financial report using deep learning, and propose an accounting model for the effects of sentiment values in financial information. For sentiment analysis with keyword detection in the financial report, we suggest the input layer with extracted keywords, hidden layers by learned weights, and the output layer in terms of sentiment scores. Our approaches can help more effective strategy for potential investors as a professional guideline using sentiment values.

The Construction Standard Production Unit(CSPU) has been used for the standard cost estimate in public and private construction projects. However, It is questionable if the reliability and/or authenticity of the system is acceptable due to the lack of consistent enactment and/or revision procedures. This study identifies informational conditions and issues relative to using daily work report as a data collection method for enacting and/or revising CSPU system, and establishes the measures for improving the daily work report. This study aims on the information constitution of daily job-site report, daily manpower report, wages register for specialty contractors. According to the research results, most of necessary data were included in a daily job-site report. In conclusion, it is investigated that data of daily manpower report and wage register need to be included in a daily job-site report for understanding the current state of worker in the future.

Objectives : The purpose of this study is to assess Traditional Korean Medicine (TKM) doctors' awareness and utilization of the case report, based on the opinion that careful observation on the case sometimes provides us with the important information as clinical trial especially in the traditional medicine research field. Methods : A questionnaire study was conducted among TKM doctors who participated in the annual continuous maintenance education (CME) held at 5 regions of the Republic of Korea. Results : Almost 60% of the respondents had read case reports published in medical journals and 67% had openly shared their clinical cases with their colleagues. Of the respondents, 18.6% had been educated on reporting cases, and only 16% had the experience of reporting cases on one's own. However, 32.6% of the respondents had the intention to report cases in the future. These results show significant differences between general physicians who holds a license but no hospital training experience and board certified TKM doctors who have training experience. Conclusions : A majority of TKM doctors have read case reports but holds little experience of having been properly trained. Through this research, it has been found that awareness of case reports is rising in hospital training. Thus, the objective of case report education for TKM doctors who have hospital training experience should be set on encouraging them to do more whereas for doctors without hospital training experience, the objective should be set on making them more exposed to case reports to heighten one's awareness.

건설 프로젝트가 더욱 복잡해지고 대형화함에 따라 정보의 양이 기하급수적으로 증가하고 있는데, 이로 인하여 프로젝트 생애주기간 실적정보를 관리하기 위한 정보 시스템이 필요하다. 특히, 작업일보 시스템은 가장 세부적인 수준에서 다양한 실적정보를 추적 관리할 수 있다는 점에서 매우 중요하다. 그러나 작업 일보 시스템의 프로세스가 시간이 많이 걸리며, 중복업무가 많고, 수집되는 정보표현의 모호성 등으로 인하여 많은 한계를 가지고 있었다. 따라서 본 연구에서는 실적정보를 수집하고 작업일보를 관리하는 프로세스를 향상시키는 것을 목적으로 To-Be 프로세스 모델을 구축하고 이를 검증하기 위해 작업일보 시스템을 개발하였다. 개발된 시스템은 interactive task generator와 작업일보관리 module로 구성되어있으며, 실제 건설프로젝트에서 성공적으로 시험되었다. 이 논문에서는 프로세스 분석, 정보모델 구축, 시스템 특징 등을 포함한 시스템 개발과정이 기술되어 있으며 연구결과와 개선효과도 논의되었다.

The present report describes the results of the cooperative experimental study organized by the High-Speed Marine Vehicle Committee of the Korea Towing Tank Conference. The study aims to improve model test technique and accuracy and to self-evaluate their own capabilities. The resistance tests of a 23m class planing hull were performed at the towing tanks of the Korea Research Institute of Ships and Ocean Engineering (KRISO), Hyundai Maritime Research Institute (HMRI), Seoul National University (SNU), Inha University (IU) and Pusan National University (PNU). In addition, the longitudinal wave cut was measured antral and analyzed at the KRISO. All the results of total resistance, trim and mean sinkage are presented in this report and the results show fairly good agreements comparing with the ITTC HSMV committee's report.

Extranodal intraoral Hodgkin lymphoma is not common. We report the case of a 78-year-old male patient with ulcer of the mandibular oral mucosa that was not cured for about 3 weeks. In biopsy and histopathologic examination, it was found to be extranodal intraoral Hodgkin lymphoma. Early diagnosis of oral lesions led to early detection of lesions of the opposite neck lymph node in an additional PET-CT scan. We report this case and review relevant literature.
