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.

As construction projects are getting more complex and larger in size, the amount of information is increased exponentially, which requires information management systems to accumulate as-built information throughout the project life-cycle. Particularly, a daily report system is very important, since it helps them keep track of various as-built information at the most detailed level. However, there have been many problems with daily reporting since its process is time-consuming and contains a lot of redundancies and ambiguities. Therefore, the objective of this research is to improve a process of collecting as-built information and managing daily report. To do so, this research developed a to-be process model and a daily report system. The daily report system developed in this research consists of interactive task generator and daily report management modules. The system has been successfully implemented in a real world construction project. The system development processes including process analysis, information models and system features are described along with discussions on the results and improvements.

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.
