본 증례는 다수의 치아 상실과 심한 치아 마모로 인해 교합 고경(occlusal vertical dimension)의 감소 및 수복 공간 부족을 보이는 환자에 대한 computer-aided design and computer-aided manufacturing (CAD/CAM) 기술을 활용한 완전 구강 회복 치료이다. 진단 단계에서 교합 고경에 대한 여러 분석을 통해 교합 고경 증가를 통한 완전 구강 회복을 계획하였다. 새롭게 설정된 교합 고경을 반영한 임시 수복물을 환자에게 적용하여 적응시키고, 이중 스캔 방법을 통해 임시 수복물의 정보를 최종 수복물에 옮긴 후, 3D 프린팅을 통해 금속 코핑을 제작하여 최종 고정성 금속 도재 수복물을 완성하였다. 이후 전자 서베잉과 3D 프린팅을 통해 가철성 국소의치 금속 구조물을 제작, 최종 가철성 국소의치로 환자치료를 완료하였다. 이러한 디지털 기술을 활용한 완전 구강 회복 치료로 환자는 기능적, 심미적으로 만족하였고, 술자는 임상적으로 받아들일 만한 치료결과로 판단하였다. This study reported the treatment of a patient with excessive worn dentition and limited maxillo-mandibular space for restoration, utilizing the computer-aided design and computer-aided manufacturing (CAD/CAM) technology. After the thorough examination of the patient's occlusal vertical dimension (OVD), full mouth rehabilitation was planned with increase of the OVD. The patient was satisfied with the provisional restorations establishing the increased OVD. The horizontal and vertical data of the patient's jaw relation that the provisional restorations contained were transferred to the definitive metal ceramic fixed prostheses by double scanning and three-dimensional printing. After the fixed restorations were cemented to the abutments, electronic surveying and three-dimensional printing were used to fabricate metal frameworks for the patient's removable partial dentures. The mandibular definitive removable prostheses were delivered to the patient's mouth and the full mouth rehabilitation procedures were completed. The digital technologies used for this case produced fixed and removable restorations satisfactory in masticatory, phonetic and aesthetic functions to both the patient and the dental clinician.

This study was performed to assess airborne fungi concentrations during fall in eight subway stations in Seoul, Korea. The purpose of this study was to investigate appropriate culture media and evaluate factors affecting airborne fungi concentrations. Results indicated that airborne fungi concentrations showed log-normal distribution. Thus, geometric mean (GM) and geometric standard deviation (GSD) were calculated. The GM of airborne fungi concentrations cultured on malt extract agar (MEA) media was 466 $cfu/m^3$ (GSD 3.12; Range 113~4,172 $cfu/m^3$) and the GM of concentrations cultured on DG18 media was 242 $cfu/m^3$ (GSD 4.75; Range 49~6,093 $cfu/m^3$). Both of GM values exceeded 150 $cfu/m^3$, the guideline of World Health Organization (WHO). There was no significant difference between two fungi concentrations cultured on MEA and DG18 media, respectively. Two factors, such as relative humidity and depths of subway stations were significantly related to airborne fungi concentrations. It is recommended that special consideration should be given to deeper subway stations for improvement of indoor air quality.

The demand of cyclotron for PET (positron emission tomography) has rapidly grown as the more use of PET or PET-CT equipment requires the increased amount of radioactive isotopes for clinical positron emission. While research on failure statistics of medical equipment used in medical centers has continued to be done, the analysis and study on failure statistics of cyclotron have rarely been conducted. However, the growing demand shows the urgency of systematical management guideline and countermeasures for device failure to minimize any supply delay of radiopharmaceuticals occurred by such failure and complains from waiting patients for PET-CT diagnosis. Therefore, this study aims to analyze the failure report from Minitrace equipped in cyclotron which is owned by the department of nuclear medicine at Yeungnam University Medical Center and draws on the data to build effective management system for cyclotron.

The purpose of this paper is to explain that the phrasal construction determines the meaning of Korean idiom phrase with two examples, mom_sal and kkoch_tun, within HPSG framework, following the spirit of concept of Construction Grammar. To do so, the paper introduces two English idiom studies of Riehemann et al.(1997) and Cho(1999) and Korean idiom explanation of Suh(1996) as the previous study. A hierarchy for Korean idiom is suggested on the basis of Cho(1999) and two criteria like semantically decomposable idiom phrase and semantically non-decomposable idiom phrase. < Hanlyo University >

『동유사서해집평(東儒四書解集評)』의 사본(寫本)과 그 가치

조준호 ( Jun Ho Cho ) 성균관대학교 대동문화연구원 2012 大東文化硏究 Vol.77 No.-

朝鮮經學의 집성을 이룬 大野柳健休(1768~1834)의 『東儒四書解集評』은 보통 石印本을 중심으로 알려져 있었다. 그런데 石印本刊印以前에 書寫된 다섯 가지 寫本이 있다. 이 寫本들은 大野의 後孫들이 보관해오다가 2003년 이후에는 한국국학진흥원에서 受託하고 있다. 이들의 구체적인 서지사항이 아직까지 학계에 구체적으로 알려진 적이 없을 뿐만 아니라, 선후 관계도 규명되어 있지 않다. 이 寫本들의 書誌事項및 내용의 變改과정을 비교하여 그 선후 관계를 따져본 결과, ①4권2책본(KS 03-3090-10117-00117) ②5책본(KS 03-3090-10134-00134) ③4책본(KS 03-3090-10139-00139) ④8권4책본(KS 03-3090-10113-00113) ⑤6권3책본(KS 03-3090-10078-00078)의 순서로 판단된다(괄호 안은 한국국학진흥원의 청구기호임). 그것은 이 寫本들이 ``계속적인 변화(Succession Variation)``를 보인 데에서 알 수 있다. 이와 같이 書誌的형태뿐만 아니라, 被釋詞(주석 대상어)의 선정, 引用자료의 배치, 引用出處表記의 변화 등을 살펴보았을 때, 후기의 寫本으로 갈수록 내용, 체제, 서체 등에서 정비되어 石印本과 가까워지고 있다. 또한 인용 자료의 取捨에있어 師承을 존중하면서도 이에 지나치게 얽매이지 않았다. 한편, 『東儒四書解集評』의 寫本들은 石印本과 차별되는 가치가 있다. 첫째, 寫本들을 통해 他書자료의 출처를 보다 더 명확하게 알 수 있다. 둘째, 『東儒四書解集評』에만 있는 내용을 교감할 때 이 寫本들은 石印本의 중요한 對校本이 된다. 셋째, 石印本에서 누락된 내용들을 모아 유용한 經說들을 輯佚할 수 있다. 넷째, 『東儒四書解集評』에 대해 기존에 알려진 정보들을 수정, 보완할 수 있다. 『Dongyusaseohaejippyeong』 by Daeya Yoo Geon-hyu (大野柳健休, 176 8~1834), who accomplished the compilation of the Joseon gyeonghak (a study of Chinese classics), gyeonghak has been known commonly from a focus on the lithographic printing edition; however, there were five transcribed copies prior to the publication of the lithographic printing edition. These copies were kept by the posterities of Daeya, but they have been entrusted to the Korea Studies Administration Center since 2003. Their detailed bibliographical items have never been known definitely by academics nor has the contextuality been identified. As a result of investigating the contextuality in comparison with their bibliographical items and the changing process of their contents, they are estimated to be in the following order: ①4 volumes 2 editions (KS 03-3090-10117-00117) ②5 editions (KS 03-3090-10134-00134) ③4 editions (KS 03-3090-10139-00139) ④8 volumes 4 editions (KS 03-3090-10113- 00113) ⑤ 6 volumes 3 editions (KS 03-3090-10078-00078). (The indication inside the parenthesis is the signs of claim by the Korea Studies Administration Center). This is determined because these copies have shown "succession variation". As such, in looking not only into their bibliographical types but also the selection of the words subjected to connotation, the placement of quoted materials, and changes in the indication of the sources of quotations, the later in the period the copies were made, the more similar they are to the lithographic printing edition as they are restructured in light of contents, systems, and hand writing. Also, in terms of the selection of quoted materials, while respecting the learning from teachers, this was not of any particular concern. Meanwhile, there is value in the copies of 『Dongyusaseohaejippyeong』 that is differentiated from that of the lithographic printing edition. First, the source of materials may be revealed more clearly through the copies. Second, when communing with the contents only in 『Dongyusaseohae- jippyeong』, these copies become imrlrtant comparison editions ng edition. First, the source of materiaird, it is rlysible to gather missing parts useful for editgyeonseol (edioe es of gyeonghak) by collecting the contents omitted in the lithographic printing edition. Fourth, it is rlysible to modify and complement information regarding 『Dongyusaseohaejippyeong』 that was not known.

Objectives: The aim of this study was to assess the association between the use of heated tobacco products (HTP) and suicidal behaviors such as suicidal ideation, suicide planning, and suicide attempts among adolescents in South Korea. Methods: The study used a cross-sectional design. Data was from the 15th Korea Youth Risk Behavior Web-based Survey (KYRBS) performed in 2019 by the Ministry of Education, Ministry of Health and Welfare, and Korean Center for Disease Control and Prevention. Heated tobacco product use was used as a main independent variable and suicide-related behaviors such as suicidal ideation, planning, and attempts were applied as dependent variables. Out of 60,100 students, 57,303 responded. Results: HTP use significantly increased the odds of a suicide attempt and suicide planning among adolescents. After controlling for confounders, when comparing ‘current HTP users’ with ‘never HTP users’, the adjusted odds ratio (OR) was 1.78 (95% confidence interval (CI): 1.38-2.30) for suicide attempts among adolescents. After controlling the confounders, comparing ‘current HTP users’ with ‘never HTP users’, the adjusted OR was 1.36 (95% CI: 1.06-1.73) for suicide planning among adolescents. For sadness/despair among adolescents, when comparing ‘current HTP users’ with ‘never HTP users’, the adjusted OR was 1.29 (95% CI: 1.11-1.50). However, HTP use had no significant association with suicidal ideation among adolescents. Conclusions: Current HTP users were more likely to attempt to commit suicide, and more likely to plan to commit suicide than never HTP users among adolescents. These results may be useful in developing a scientific basis for designing suicide prevention programs targeting adolescents.
