This study is to evaluate the drought-related bigdata characteristics published from South Korean by developing crawler. The 5 years (2013 ~ 2017) drought-related posted articles were collected from Korean internet search engine 'NAVER' which contains 13 main and 81 local daily newspapers. During the 5 years period, total 40,219 news articles including 'drought' word were found using crawler. To filter the homonyms liken drought to soccer goal drought in sports, money drought economics, and policy drought in politics often used in South Korea, the quality control was processed and 47.8 % articles were filtered. After, the 20,999 (52.2 %) drought news articles of this study were classified into four categories of water deficit (WD), water security and support (WSS), economic damage and impact (EDI), and environmental and sanitation impact (ESI) with 27, 15, 13, and 18 drought-related keywords in each category. The WD, WSS, EDI, and ESI occupied 41.4 %, 34.5 %, 14.8 %, and 9.3 % respectively. The drought articles were mostly posted in June 2015 and June 2017 with 22.7 % (15,097) and 15.9 % (10,619) respectively. The drought news articles were spatiotemporally compared with SPI (Standardized Precipitation Index) and RDI (Reservoir Drought Index) were calculated. They were classified into administration boundaries of 8 main cities and 9 provinces in South Korea because the drought response works based on local government unit. The space-time clustering between news articles (WD, WSS, EDI, and ESI) and indices (SPI and RDI) were tried how much they have correlation each other. The spatiotemporal clusters detection was applied using SaTScan software (Kulldorff, 2015). The retrospective and prospective cluster analyses were conducted for past and present time to understand how much they are intensive in clusters. The news articles of WD, WSS and EDI had strong clusters in provinces, and ESI in cities.

Background: Swallowing function deterioration is a common problem experienced by older adults worldwide. Many studies have been conducted to improve swallowing function in older adults; however, due to differences in intervention methods and study designs, it is difficult to draw a common conclusion. This study aimed to analyze trends and intervention methods in studies of swallowing function intervention for older adults conducted from 2010 to 2022, to establish a systematic approach for developing interventions to improve swallowing function in older adults and to provide evidence for this approach. Methods: Literature research was conducted for studies published between 2010 and 2022 that applied to swallow function interventions to adults aged 60 years or older. Databases including PubMed, Medline, RISS, Science On, KISS, and KCI were used. From a total of 1,164 articles searched using keywords, 20 articles were selected for final analysis. Results: The number of published articles steadily increased over time, and the intervention period was most commonly 6 or 8 weeks. The types of interventions included focused exercises to improve oral muscle strength in 12 articles and programs incorporating education, practice, and expert management in 8 articles. Among the focused exercises, tongue-strengthening exercises were most common in 4 articles. The evaluation variables for intervention effects were muscle strength evaluation, oral function evaluation, quality of life, and oral health and hygiene status. Muscle strength and oral function evaluations were statistically significant in focused exercise interventions, while the quality of life and oral health and hygiene status was significant in program interventions. Conclusion: This literature review is meaningful as a study that can be used to select the intervention period and program contents when planning an elderly swallowing intervention program.

This study examines how the concept of gender fluidity-viewing gender identity as a fluid and wide spectrum-is represented in modern knit fashion collections. The period spring/summer 2017-fall/winter 2021, when gender-related fashion keywords started attracting attention, was limited to the last five years, and the results of a case analysis focused on a total of 357 knit fashion photos are as follows. First, the androgynous compromise through the mixing of heterogeneous elements appears as a mix-and-match style due to the patchwork of heterogeneous materials and forms that borrow or share masculinity and femininity. Second, it was confirmed that the dismantling exaggeration caused by the destruction of the size and form of clothes was an avant-garde image that exaggerated the size or length of clothes or destroyed ideas and forms. Third, the exposed sensuality caused by the deformation of the fluid knitting technique was shown in the form of proudly expressing sexuality by exposing the body either using the cut-out technique or through the loose texture of the knit. Knit fashion can highlight decorative effects using handcrafted techniques and express a detailed or coarse sense of organization depending on the density. In addition, since it is possible to create a complex image by juxtaposing and mixing various knit structures, it was confirmed that it is a suitable material for expressing gender fluidity flowing between men and women in fashion.

Mobile phones have become an essential item nowadays since it provides access to online platform and service fast and easy. Coming to these platforms such as Social Network Service (SNS) for shopping have been a go-to option for many people. However, searching for a specific fashion item in the picture is challenging, where users need to try multiple searches by combining appropriate search keywords. To tackle this problem, we propose a system that could provide immediate access to websites related to fashion items. In the framework, we also propose a deep learning model for an automatic analysis of image contexts using instance segmentation. We use transfer learning by utilizing Deep fashion 2 to maximize our model accuracy. After segmenting all the fashion item objects in the image, the related search information is retrieved when the object is clicked. Furthermore, we successfully deploy our system so that it could be assessable using any web browser. We prove that deep learning could be a promising tool not only for scientific purpose but also applicable to commercial shopping.

연구 동향을 파악하는 것은 연구 수행 시 필수적인 요소이다. 대부분의 연구자들은 관심분야의 학술대회 및 저널을 대표하는 기술 핵심구나 관심 분야를 검색함으로써 연구 동향을 파악한다. 하지만, 최근 인공지능과 같은 특정 분야의 경우 한 개의 학술대회에 한 해당 수백~수천 개의 논문이 출간되기 때문에 전체 분야의 경향성을 파악하는 데 어려움이 존재한다. 본 논문에서는 학술대회 또는 저널 제목을 활용하여 기술 핵심구를 자동으로 추출함으로써 연도별 학술대회 및 저널의 연구 동향 파악을 지원하고자 한다. 핵심구 추출은 문장 또는 문서를 대표하는 주요 구문을 추출하는 작업으로서 검색, 요약, 내용 파악 등을 위해 근간이 되는 기술이다. 기존 사전학습 언어모델 기반의 핵심구 추출 모델은 문서 단위의 긴 텍스트를 기준으로 모델링 하였기 때문에 제목 단위의 짧은 텍스트에서는 성능이 낮아진다는 단점이 존재한다. 본 논문에서는 짧은 텍스트에 강인하면서 단어 자체의 중요도를 고려한 학술대회 및 저널의 기술 핵심구 추출 모델을 제안하고자 한다.

The advent of big data has brought about the need for analytics. Natural language processing (NLP), a field of big data, has received a lot of attention. Topic modeling among NLP is widely applied to identify key topics in various academic journals. The Korean Society of Industrial and Systems Engineering (KSIE) has published academic journals since 1978. To enhance its status, it is imperative to recognize the diversity of research domains. We have already discovered eight major research topics for papers published by KSIE from 1978 to 1999. As a follow-up study, we aim to identify major topics of research papers published in KSIE from 2000 to 2022. We performed topic modeling on 1,742 research papers during this period by using LDA and BERTopic which has recently attracted attention. BERTopic outperformed LDA by providing a set of coherent topic keywords that can effectively distinguish 36 topics found out this study. In terms of visualization techniques, pyLDAvis presented better two-dimensional scatter plots for the intertopic distance map than BERTopic. However, BERTopic provided much more diverse visualization methods to explore the relevance of 36 topics. BERTopic was also able to classify hot and cold topics by presenting 'topic over time' graphs that can identify topic trends over time.

Purpose : This study systematically reviewed occupational therapy programs for upper extremity functions in subacute patients implemented over the last decade at home and abroad to utilize the findings as the basis for intervention protocols. Methods : This study was conducted with domestic and foreign randomized controlled experimental studies published from January 2013 to May 2023. Acute or subacute, CVA or stroke, upper extremity function, and program or therapy were used as search keywords in the search databases Scopus, PubMed, Riss, and DBpia. A total of 3,723 documents were retrieved, and 1,007 duplicate papers were excluded. In addition, 2,640 papers that did not meet the inclusion and exclusion criteria were excluded by the researcher examining the titles and abstracts. Thereafter, the full texts were checked. Consequently, 67 documents were excluded, and nine documents were finally used for analysis. Results : Due to the evaluation of the quality of the documents of nine studies, five items were rated "low," and two items were rated "unclear" in many studies. Males predominated the genders, and infarction predominated the types. The average age was over 50 but under 60 years, and the number of days after onset was predominantly fewer than one month. Occupational therapy programs were classified into mental programs, mirror therapy, music programs, and virtual reality programs, and virtual reality programs were frequently used. The intervention periods were predominantly 15-30 sessions for less than 30 minutes, and the Fugl-Meyer assessment-upper extremity was predominantly applied as an evaluation tool. Conclusion : This study is significant because it attempted to present the direction of intervention protocols for upper extremity functions in subacute stroke patients in clinical settings. Studies should be conducted with an expanded scope for a literature review.

Objectives : The purpose of this study is to analyze the oriental medical treatments of burning mouth syndrome, understand the tendency of treatment, and apply it to clinical settings. Methods : We collected case reports, retrospective cohort studies and RCT studies related to oriental medical treatments of burning mouth syndrome using domestic and Chinese databases(CNKI, KISS, RISS, OASIS, KCI). Search terms include 'Burning Mouth Syndrome', 'BMS', 'Burning Tongue', '灼口综合征', and 'oriental medicine', 'oriental medical treatment', 'Korean medicine' and '中医'. A search was conducted by appropriately combining keywords. Results : A total of 27 papers were included in the analysis. Among them, 9 are case studies, 1 is a retrospective cohort study, 1 is a before and after study and 16 are RCT studies. Treatments for burning mouth syndrome included herbal medicine, acupuncture, electro-acupuncture, acupoint injection, auricular acupuncture treatment, external use herbal medicine and gargling. In all studies, symptoms of burning mouth syndrome were alleviated after oriental medical treatments. In 14 RCT studies comparing western medical treatments, the results of the treatment group that included oriental medical treatments were found to be more significant, except for one. Conclusions : As a result of the study, oriental medical treatments are effective in treating burning mouth syndrome. In the future, we hope that clinical research related to oriental medical treatments of burning mouth syndrome will be actively conducted so that evidence-based treatment can be implemented.
