In this paper, we propose the improvement of Hangul OCR accuracy through deep learning. OCR is a program that senses printed and handwritten characters in an optical way and encodes them digitally. In the case of the most commonly used Tesseract OCR, the accuracy of English recognition is high. However, Hangul has lower accuracy because it has less learning data for a complex structure. Therefore, in this study, we propose a method to improve the accuracy of Hangul OCR by extracting the character region from the desired image through image processing and using deep learning using it as learning data. It is expected that OCR, which has been developed only by existing alphanumeric and several languages, can be applied to various languages.

In the circumstances of overflowing numbers of medical journals, progress of their own medical journal is one of the primary concerns of many medical societies. Among the 46-year-history of Journal of Korean Neurosurgical Society (JKNS), it undertook a period of important transition and preparation to take off for journal with international reputation during the period from 2001 to 2006. The overall process of manuscript handling, peer review, and editorial work has undergone systematic improvement. Workshops for authors, reviewer and editors were held, which were very helpful to improve the quality of submitted manuscript, peer review and editorial processing. Articles on the history, current status of the JKNS, citations and the change of proportion of types of articles were published, which provided insight about present condition and direction for further progress. It was changed into English journal in 2005. These efforts resulted in registration of the journal Chemical Abstract Service in 2005 and Science Citation Index Expanded in 2008 and SCOPUS in 2009. Now JKNS has become international journal, with about half of the submitted manuscripts from abroad, with increasing impact factor. Along with the effort of Korean Neurosurgical Society (KNS) members and support of KNS, dedication of Professor Dong Gyu Kim for the progress of JKNS is worth remembering, who served as Editor-in-Chief of JKNS during this period.

Purpose: Carcinosarcomas are rare neoplasms in which both malignant epithelial and mesenchymal elements are identified. We have found only twenty one cases of primary cutaneous carcinosarcoma in the English language literature. Therefore it has been difficult to diagnosis because its unclear etiology and low frequency. Methods: A 31-year-old young man with a protruding mass on his ankle dorsum was examined. The tumor was $7{\times}6{\times}3\;cm$ sized and arose from a burn scar. The mass was wide excised and applied split thickness skin graft. Characteristic pathologic finding was a mixture of squamous cell carcinoma and malignant fibrous histiocytoma. Results: Three months after the operation, the patient died of multiple metastasis to the liver, lung and finally of sepsis despite adjuvant chemotherapy and adjuvant radiotherapy. Conclusion: If a metastatic cutaneous carcinosarcoma is diagnosed, wide excision is required. There should be more aggressive management to minimize the risk of recurrence. Further research into the etiology and pathophysiology of the disease and a more careful differential diagnosis may allow improvement in treatment.

Objectives The purpose of this study was to systematically review previous studies on constitutional herbal medicine treatment for the obesity. Methods A total of 11 databases were searched in English, Chinese, and Korean. Standard methodologies for the systematic review were used to search, analyze and synthesize data for undertaking review and meta-analysis for intervention. The risk of bias was assessed by two independent researchers using the Cochrane risk of bias. Results A total of 2 RCTs were selected and analyzed. The results of the meta-analysis showed a significantly positive effect in the body weight and body mass index for the patient group treated with Taeeumjowi-tang compared to the placebo control group. Conclusions Our results suggested that Taeeumjowi-tang could be considered for improvement of symptoms in obese patients, without serious adverse events. Due to the low quality of the clinical evidence in this study, further studies are needed to evaluate efficacy and safety of constitutional herbal medicines for obesity.

Objectives: The purpose of this study was to evaluate the effectiveness and safety of traditional herbal medicine as a stand-alone treatment group through major English databases due to the lack of RCTs in Korea, and to provide a review of the herbal interventions used. Methods: Using four databases (Pubmed, EMBASE, OASIS, RISS), combination of words such as "Coronavirus" "RCT" "Herb" "Decoction" "TCM" were used. RCTs using herbal medicines to treat coronavirus were searched. Final 4 studies were selected by two authors according to inclusion and exclusion criteria. Results: A total of 1,435 patients were studied. The Chinese herbs used in the treatment group were Shengmai Yin, JingYinGuBiao granules, Jinhua Qinggan granules, and Bufei Huoxue capsules. The intervention group showed greater attenuation of pneumonia lesions on CT. Also, improvement in 6-min walk distance (6MWD), and negative conversion rate in treatment group were reported. Furthermore, scores on the Fatigue Assessment Inventory (FAI) were lower in the herbal group than in the placebo group. The median time to recovery of COVID-19 related symptoms was shorter in TCM group compared to the control group. Reported adverse effects were diarrhea, liver dysfunction, and excessive menstruation, and two papers did not mention side effects in detail. Conclusion: Herbal medicine alone can increase the conversion rate of viral negativity and relieve COVID-19 related symptoms without significant adverse effects.

The purpose of this study was to seek strengths and weaknesses from analyzing Korea and U.S. science textbooks in terms of general structural features, contents, cognitive levels of questions and the purpose of questions used in science textbooks. This provided insight into improvement of textbooks that can effectively assist teaching and learning. To investigate organization of unit in textbooks in-depth, the evolution unit was selected and scrutinized as one example. The results showed that the number of pages, activities, vocabulary words, and vocabulary lists are considerably different between Korean and the U.S. Commonly, U.S. textbooks were more laden with information and lacking in coherence than those of the Korean textbooks. The findings on the cognitive levels of questions showed that the majority of questions in both nations are concerned with knowledge. However, the difference between the two nations is great in the ratios of analysis, synthesis, and evaluation questions. Questions are concentrated in review section (45% of Korean and 60.6% of U.S.) in textbooks. It suggested that well-planned questions in a review section can provide the basic guidance for strength in a science classroom.

Purpose: The purpose of this study was to review and synthesize the existing literature on the experience of nursing students in simulation. Methods: A systematic review was undertaken using meta-ethnography. Eight databases were searched up to January 2014 for peer-reviewed studies, written in Korean and English, that reported primary data, used identifiable and interpretative qualitative methods, and offered a valuable contribution to the synthesis. Results: Nine studies were identified, with quality appraisal undertaken. Three key concepts were generated: ambivalence of simulation practice, learning by reflection, and building up of the competency as a future nurse. Six sub-concepts emerged: double sidedness of simulation setting; feeling ambivalence of simulation; learning from others; learning from self-reflection; improvement of confidence by role experience; and internalization of nursing knowledge. A line of argument has been developed based on the themes generated. Conclusion: The findings from this qualitative synthesis and other related literature indicated the importance of capability of educator and extension of the simulation system to facilitate effective simulation-based education.
