Purpose: Due to the nature of heatwave research, where research is conducted for a variety of subjects and purposes, it is important to anticipate research trends and development directions in order to improve the quality of the research. Therefore, in order to provide basic data that can suggest the current status of heatwave research and the direction of future research, we tried to examine the trends of heatwave-related research. Method: Heatwave studies published in academic journals registered with the National Research Foundation of Korea from 2011 to 2020 were analyzed by classifying them according to the research period, the purpose of the study, the research subjects and the research method. Result: The main research results are as follows. First, as interest in heatwaves increases, the number of heatwave studies also increases. Second, the purpose of heatwave research is biased and needs to be studied from various perspectives. Third, although various research subjects were used, an even study was not conducted. Fourth, under the influence of the research purpose, the bias of the research method appeared together. Conclusion: The damage caused by the heat wave is persistent and has a widespread impact. In order to manage, prevent, and respond to such heat waves as disasters, equal research should be conducted in various fields.

This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

The demand for noise barriers and necessity for the installation are highly growing because residential areas have become diverse and locational priority is changed to consider how to approach highway easily. However, public annoyance to the noise generated from highway is continued despite lots of noise barrier are installed. Moreover, there are growing concerns to maintain noise barriers to be free from losing transparency, dust stack, and shock fracture. To resolve these issues, it is suggested to develop new polymer materials and conceptually new noise barrier. In this study, as a first step to develop a new noise barrier to overcome current technological challenges as well as economic issues, recent research trends have been analyzed and found the direction for the future research in terms of material, supplementary function, and patterning.

AI education is being emphasized nationwide as a literacy education. At this point, it is necessary to identify critical issues and suggest the direction of future research by examining domestic AI education research trends. To this end, the study applied the scoping review method. A total of 29 AI educational studies from 2017 to 2020 in South Korea were analyzed. As a result, it was confirmed that the number of studies increased rapidly in 2020, and a large proportion of studies targeted elementary school students. In addition, the study found that AI principles were treated as contents at a high rate, both cognitive and affective aspects were frequently reported as a learning outcome, and various practice environments were used relatively evenly. Based on the results, the direction of future research was discussed and suggested.

This study analyzed Korean studies up to August 2023 to suggest the direction of future research on basic academic abilities in mathematics. For this purpose, frequency analysis and LDA-based topic modeling were conducted on the Korean abstracts of 197 domestic studies. The results showed that, first, 'academic achievement', 'impact', 'effect', and 'factors' were all ranked at the top of the TFs and TF-IDFs. Second, as a result of LDA-based topic modeling, five topics were identified: causes of basic academic abilities deficiency, learning status of math underachievers, teacher expertise in teaching math underachievers, supporting programs for math underachievers, and results of National Assessment of Educational Achievement. As a direction for future research, this study suggests focusing on the growth of math underachievers, systematizing the programs provided to students who need learning support in mathematics, and developing teacher expertise in teaching math underachievers.

Over 100 countries have conducted research on experimental testing methods to assess the frost susceptibility of soils. This study aims to prevent structural damage caused by frost heave. Notably, the United States and Japan, which encompass cold regions such as Alaska and Hokkaido, have actively pursued frost heave research. Through laboratory investigations and field applications, standard testing methods and criteria for evaluating frost susceptibility have been established. However, these methods are complex and their engineering explanations are vague. This study closely compares and analyzes the frost-susceptibility testing methods proposed by ASTM and JGS, considering temperature conditions, specimen size, freezing direction, and drainage conditions. By conducting this comparative analysis, this study aims to shed light on the similarities and differences between the two methods. Furthermore, based on the findings, this study proposes future research guidance for refining frost-susceptibility testing methods and criteria.

With the advances of the big-data process technology, acquiring the real-time information from the massive image data taken by a mobile device inside a vehicle will be possible in the near future. Among the information that can be found around the vehicle, the route information is needed for safe driving. In this study, the automatic extraction of route information from the road sign imagery was dealt with. The scope of the route information in this study included the route number, route type, and their relationship with the driving direction. For the recognition of the route number, the modified Tesseract OCR (Optical Character Recognition) engine was used after extracting the rectangular-road-sign area with the Freeman chain code tracing algorithm. The route types (expressway, highway, rural highway, and municipal road) are recognized using the proposed algorithms, which are acquired from colour space analysis. Those road signs provide information about the route number as well as the roads that may be encountered along the way. In this study, such information was called “OTW (on the way)” or “TTW (to the way)” which between the two should be indicated is determined using direction information. Finally, the route number is matched with the direction information. Experiments are carried out with the road sign imagery taken inside a car. As a result, route numbers, route number type, OTW or TTW are successfully recognized, however some errors occurred in the process of matching TTW number with the direction.

Based upon the research and analysis on the downtown residents' satisfaction with their current housing areas and preference for future housing areas, this study clarifies the following. First, the breakdown on various factors influencing the housing environment indicates that downtown residents are the most satisfied with the easy access to the public transportation, and cultural and commercial facilities. Second, they are not content with the amenity aspects such as the air, noise, and the surrounding views, and the economic aspects such as the prices of the houses and the prospects for future investment. The low satisfaction suggests that the amenity aspects and economic aspects should be considered for future downtown housing development. Third, more than half of the residents in downtown areas still prefer to dwell in downtown areas. In the future downtown development, the close analysis on the characteristics of downtown dwelling, and the researches on the right direction of downtown housing development for the whole citizens of Daegu should be done in advance. Last, the majority of people wishing to reside in downtown want medium- or large-scale apartment complexes. In the future downtown housing development, it should be focused on the downtown residence with complex functions rather than on the small-scale maintenance projects.
