Purpose : The purpose of this study was to investigate the coincidence between keywords of Journal of the Korean Society of Physical Medicine (JKSPM) and MeSH terms, a controlled vocabulary used in MEDLINE. Methods : A total of 838 keywords used in 252 papers of JKSPM from Vol.1, No.1, 2006 to Vol.7, No.1, 2012 were compared with MeSH terms. All of keywords are classified to three large categories; complete coincidence, incomplete coincidence, and complete incoincidence. Results : The keywords in complete coincidence category were 183(21.8%), the keywords in incomplete coincidence category were 378(45.1%), and the keywords in complete incoincidence category were 277(33%). The most used keyword in complete coincidence category was 'stroke' and in complete incoincidence category was 'balance'. The most used keyword matching entry terms in incomplete coincidence category was 'elderly'. Conclusion : The rate of complete coincidene of keywords with MeSH terms was not higher than the rates of incomplete coincidence and complete incoincidence. It is necessary to understand MeSH terms more accurately and specifically. The JKSPM should ask the authors to use MeSH terms as keyword when they submit the paper.

Nowadays, research data repositories (RDR) have become progressively widespread all over the world. To expand repository services and build up inbound linking strategy, organizations list their repositories with so called Global Registries. Accordingly, such registries should be carefully described by the related data. In this study, I explore the metadata schema of re3data.org. I collect and analyze descriptions from the listed repositories, and come up with some suggestions concerning possible improvements to the metadata schema. To accomplish this, I develop a crawler program, which collects necessary data from the re3data.org. Based on the analysis results, I have identified two issues that required elements is missing, one issue that required element value is missing when the corresponding property is applied, five inconsistency issues with re3data controlled vocabulary, six issues with undescribed optional elements, and two inconsistency issues between the elements and their attributes which do not pair with. I believe this discussion can facilitate improvements to the existing re3data.org schema and further help researchers who analyze data repository trends.

Purpose: The clivus is a region in the anterior section of the occipital bone that is commonly imaged on large-volume cone-beam computed tomography (CBCT). There have been several reports of incidental clivus variations and certain pathological entities that have been attributed to the variations. This study aimed to evaluate the effects of these variations within the scope of dentistry. Materials and Methods: Medical databases (PubMed, Scopus, and Web of Science) were searched using a controlled vocabulary (clival anomalies, cone-beam CT, canalis basilaris medianus, fossa navicularis magna, clival variation). The search was limited to English language, humans, and studies published in the last 25 years. The articles were exported into RefWorks^® and duplicates were removed. The remaining articles were screened and reviewed for supporting information on variations of the clivus on CBCT imaging. Results: Canalis basilaris medianus and fossa navicularis magna were the most common anomalies noted. Many of these variations were asymptomatic, with most patients unaware of the anomaly. In certain cases, associated pathologies ranged from developmental (Tornwaldt cyst), to acquired (recurrent meningitis). While no distinct pathognomonic aspects were noted, there were unique patterns of radiographic diagnosis and treatment modalities. Most patients had a normal course of follow-up. Conclusion: Interpretation of CBCT volumes is a skill every dentist must possess. When reviewing large-volume CBCT scans, the clinician should be able to distinguish pathology from normal anatomic variations within the skull base. The majority of clivus variations are asymptomatic and will remain undetected unless incidentally noted on radiographic examinations.

Objective: This study aims to measure cognitive load levels by analyzing the EEG of Koreans and foreigners, when they read a Korean text with care selected by level from the grammar and vocabulary aspects, and compare the cognitive load levels through quantitative values. The study results can be utilized as basic data for more scientific approach, when Korean texts or books are developed, and an evaluation method is built, when the foreigners encounter them for learning or an assignment. Background: Based on 2014, the number of the foreign students studying in Korea was 84,801, and they increase annually. Most of them are from Asian region, and they come to Korea to enter a university or a graduate school in Korea. Because those foreign students aim to learn within Universities in Korea, they receive Korean education from their preparation for study in Korea. To enter a university in Korea, they must acquire grade 4 or higher level in the Test of Proficiency in Korean (TOPIK), or they need to complete a certain educational program at each university's affiliated language institution. In such a program, the learners of the Korean language receive Korean education based on texts, except speaking domain, and the comprehension of texts can determine their academic achievements in studying after they enter their desired schools (Jeon, 2004). However, many foreigners, who finish a language course for the short-term, and need to start university study, cannot properly catch up with university classes requiring expertise with the vocabulary and grammar levels learned during the language course. Therefore, reading education, centered on a strategy to understand university textbooks regarded as top level reading texts to the foreigners, is necessary (Kim and Shin, 2015). This study carried out an experiment from a perspective that quantitative data on the readers of the main player of reading education and teaching materials need to be secured to back up the need for reading education for university study learners, and scientifically approach educational design. Namely, this study grasped the difficulty level of reading through the measurement of cognitive loads indicated in the reading activity of each text by dividing the difficulty of a teaching material (book) into eight levels, and the main player of reading into Koreans and foreigners. Method: To identify cognitive loads indicated upon reading Korean texts with care by Koreans and foreigners, this study recruited 16 participants (eight Koreans and eight foreigners). The foreigners were limited to the language course students studying the intermediate level Korean course at university-affiliated language institutions within Seoul Metropolitan Area. To identify cognitive load, as they read a text by level selected from the Korean books (difficulty: eight levels) published by King Sejong Institute (Sejonghakdang.org), the EEG sensor was attached to the frontal love (Fz) and occipital lobe (Oz). After the experiment, this study carried out a questionnaire survey to measure subjective evaluation, and identified the comprehension and difficulty on grammar and words. To find out the effects on schema that may affect text comprehension, this study controlled the Korean texts, and measured EEG and subjective satisfaction. Results: To identify brain's cognitive load, beta band was extracted. As a result, interactions (Fz: p =0.48; Oz: p =0.00) were revealed according to Koreans and foreigners, and difficulty of the text. The cognitive loads of Koreans, the readers whose mother tongue is Korean, were lower in reading Korean texts than those of the foreigners, and the foreigners' cognitive loads became higher gradually according to the difficulty of the texts. From the text four, which is intermediate level in difficulty, remarkable differences started to appear in comparison of the Koreans and foreigners in the beginner's level text. In the subjective evaluation, interactions were revealed according to the Koreans and foreigners and text difficulty (p =0.00), and satisfaction was lower, as the difficulty of the text became higher. Conclusion: When there was background knowledge in reading, namely schema was formed, the comprehension and satisfaction of the texts were higher, although higher levels of vocabulary and grammar were included in the texts than those of the readers. In the case of a text in which the difficulty of grammar was felt high in the subjective evaluation, foreigners' cognitive loads were also high, which shows the result of the loads' going up higher in proportion to the increase of difficulty. This means that the grammar factor functions as a stress factor to the foreigners' reading comprehension. Application: This study quantitatively evaluated the cognitive loads of Koreans and foreigners through EEG, based on readers and the text difficulty, when they read Korean texts. The results of this study can be used for making Korean teaching materials or Korean education content and topic selection for foreigners. If research scope is expanded to reading process using an eye-tracker, the reading education program and evaluation method for foreigners can be developed on the basis of quantitative values.

의학학술문헌에는 해부학적 조직이나 기관명이 종양, 질환 또는 감염 용어들과 서로 조합하여 사용되는 언어적 특성을 가지고 있다. 의학학술문헌을 검색할 때 데이터베이스가 제공하는 통제어휘도구인 Medical Subject Headings (MeSH)를 활용하면 합성어, 동의어, 그리고 관련어를 추가로 검색할 수 있어 검색효율이 높다. 본 연구에서는 위암(Stomach Neoplasms) 어휘군을 검색용 필터로 추가하는 방법과 동시출현용어의 거리를 측정하여 단어인접탐색 기법으로 검색효율성을 향상시키는 연구를 수행하였다. 검색용 MeSH에 추가할 어휘군을 결정하기 위해 실험데이터로 PubMed에서 중심주제어가 "Stomach Neoplasms"인 2007년~2016년 논문 8,625편을 내려 받아 논문제목으로부터 Stomach와 Neoplasms 관련 용어의 동시출현여부를 분석하였다. 검색효율성은 KoreaMed에서 검색되는 MEDLINE 학술지를 대상으로 "Stomach Neoplasms"가 MeSH로 색인되어 있는 277편으로 검증하였는데 MEDLINE MeSH, MeSH on Demand, 그리고 KoreaMed MeSH Indexer의 "Stomach Neoplasms" 색인어 추출여부와 검색용 필터로 어휘군을 적용했을 때, 그리고 동시출현 용어의 단어인접검색 기법을 적용했을 때 "Stomach Neoplasms"의 매칭여부를 비교하였다. 가장 출현빈도가 높은 용어는 "Gastric Cancer"로 2,780회 출현하였다. "Gastric Adenocarcinoma", "Gastric MALT Lymphoma" 등과 같이 "Stomach" 용어와 "Neoplasms" 관련 조직학적 용어가 조합된 경우는 7,376개(88.51%)였다. 동시출현 거리가 2단어인 용어는 "Stomach"와 "Neoplasms"의 합성어로 5,234개(70.95%)였다. 연구 결과 MeSH용어를 제외하고 973개의 용어를 후보어휘군으로 선정하였다. MEDLINE MeSH와 KoreaMed MeSH Indexer의 MeSH 매칭률은 209편(75.5%)이었는데 검색필터를 적용한 결과 263편(94.9%)으로, 동시출현 용어의 13단어 단어인접탐색 기법을 적용한 경우 268편(96.7%)으로 매칭률이 향상되었다. 본 연구를 통해 자연어 검색에 있어서 검색효율을 향상시키는 수단으로 검색용 시소러스를 사용하면 색인비용에 대한 부담이 적고, 통제어의 망라적 장점과 자연어가 가지는 용어의 특정성을 유지할 수 있음을 증명하였다. 또한 불리안 검색보다는 단어인접탐색 기법을 활용하면 정확률을 높일 수 있어 검색 효율성이 향상됨을 알 수 있었다.

Objective: Various controlled vocabulary such as thesaurus and classification make us to reuse and share effectively by defining different concept and linking terms each other. The UMLS(Unified Medical Language System) is one of the most universal medical terminology systems. It is needed various methods to share and reuse information of traditional Korean medicine. We will research on method that adopt SUI of the UMLS(that is de facto standard in medical terminology system) in traditional Korean medical terminology. Method: We described major problems and applying process when we tried to add traditional Korean medicine in the part of meridian into the UMLS metathesaurus. Comparing western medical terms and traditional Korean medical terms for applying UMLS metathesaurus, there is not only many consistency, but also differences. Result: We confirmed what is the differences and consistency between western medical terms and traditional Korean medical terms. And then reviewed methods that apply the CUI, LUI, SUI in traditional Korean medical terms. Traditional Korean medical terms are not discriminated by singular or plural string. In addition, traditional Korean medical terms have vary string by initial law: the law of initial sound of a syllable. Character is described with Korean, traditional Chinese, modern Chinese, etc. According to meaning, language, initial law, SUI has a distinct value respectively. Conclusion: There are many differences to apply the UMLS between western medical terms and traditional Korean medical terms. For the better implementation to traditional Korean medicine into the UMLS, further research is needed in standardization and classification of traditional Korean medical terms, medical information system, etc. We hope this study helps the implementation UMLS, EHR, knowledge based system in Oriental medicine in the future.

Background: The purpose of this study was to analyze the equality between key words used in the Journal of Korean Dental Society of Anesthesiology and Medical Subject Headings (MeSH). Methods: A total of 666 English key words in 187 papers (average 3.5 words in a paper) from 2001 to 2014 were eligible for this study. We classified them according to matched, and non-matched terms. After descriptive analysis, we assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. Results: Fifty nine point six percent (59.6%) of total key words were completely coincident with MeSH terms, 40.39% were not MeSH terms. Conclusions: The results show that the coincidence rate of key words with MeSH terms was at a moderate level. However, there is a need for us to understand MeSH more specifically and accurately. Use of proper key words aligned with the international standards such as MeSH is important to be properly cited. The authors should pay attention and be educated on correct use of MeSH as key words.
