목적: 본 연구의 목적은 구치부 식립 임플란트에서 지대주 나사 풀림의 발생 빈도 및 지대주 나사 풀림에 영향을 주는 다양한 요인들을 후향적 연구를 통하여 평가하는 것이다. 대상 및 방법: 2013년 1월부터 2016년 1월까지 208명의 환자에서 구치부에 식립한 391개의 임플란트를 대상으로 하였다. 모든 수복물은 고정성으로 단일 혹은 연결 크라운, 브릿지로 제작되었으며, 임시 시멘트로 합착하였다. 전체 수복물 중 지대주 나사 풀림의 발생 빈도를 조사하였고, 성별, 보철물의 위치, 대합치, 보철물의 유형, 지대주 연결 유형, 매식체의 지름이 지대주 나사 풀림에 미치는 영향을 평가하였다. 결과: 2 - 5년의 관찰 결과, 총 29개(7.4%)의 임플란트에서 지대주 나사 풀림이 발생하였다. 최종 수복 후 지대주 나사 풀림이 발생하기까지 소요된 기간은 3개월부터 48개월(평균19.5개월)까지 다양하게 나타났으며, 이 중 3개의 임플란트에서 매식체의 파절이 발생되었다. 고려 요인들 중, 임플란트의 식립 위치에 따라 대구치(9.4%)와 소구치(2.6%)에서 통계적으로 유의한 차이를 보였으며(P < .019), 대합치에 따라 자연치(9.9%), 임플란트(1.0%), 가철성 보철물(0%)에서 유의한 차이를 보였다(P < .018). 다른 고려 요인에 따른 지대주 나사 풀림 발생 빈도는 통계적 유의성이 없었다. 결론: 구치부 임플란트 수복물에서 지대주 나사 풀림의 발생 빈도는 7.4%로 나타났다. 소구치보다 대구치에서 유의하게 높은 발생 빈도를 보였으며, 대합치에 따라서는 임플란트, 가철성 보철물과 비교 시 자연치에서 유의하게 높은 발생 빈도를 보였다. Purpose: This study was to assess clinically the incidence of abutment screw loosening of posterior implant-supported fixed prosthesis and its affecting factors. Materials and methods: 391 implant-supported crowns restored from January 2013 to January 2016 were included in this study. All restorations were fabricated with either a single crowns or a splinted crown, and cemented with temporary cement. The incidence of abutment screw loosening is investigated and gender, restoration position, opposing teeth, restoration type, abutment connection type were assessed as possible factors affecting abutment screw loosening. Results: During the observation period (2 - 5 years), abutment screw loosening was found in 29 restorations (7.4%). It took 3 to 48 months (means 19.5 months) to loose the screw, and three of these implants were fractured. Among the factors considered, there were statistically significant differences at abutment screw loosening rate between molar group (9.4%) and premolar group (2.6%) (P<.019). According to the type of opposing teeth, there were statistically significant differences between nature teeth (74.7%) and implant (25.0%), removable denture (3%) (P<.019). The other possible factors did not have a significant effect on loosening of the abutment. Conclusion: The incidence of abutment screw loosening in posterior restoration was 7.4%. Abutment screw loosening were more likely to occur in molars group than premolar group, and according to the opposing teeth, there were the greatest frequency in nature teeth than implant and removal denture. There was a statistically significant difference.

PURPOSES: In this paper, the effectiveness of speed-maintained standardization in road geometry on environmental impact at a downward slope location, based on greenhouse gas (GHG) emission indicators, was studied. Specifically, the aim of this study was to ascertain whether speed-maintained standardization resulted in decreased CO2 emissions as well as noise pollution, due to reduced vehicle speeds. METHODS : In this study, speed-maintained standardization in road geometry was proposed as a means to reduce vehicle speeds, with a view to reducing CO2 emissions and noise pollution. This technique was applied at a downward slope location. The vehicle speeds, CO2 emissions, and noise levels before and after application of speed-maintained standardization were compared. RESULTS: It was found that speed-maintained standardization was effective as a means to reduce speed, as well as CO2 emissions and noise pollution. By applying speed-maintained standardization, it was confirmed that vehicle speeds were reduced consistently. As a result, CO2 emissions and noise levels were decreased by 9% and 11%, respectively. CONCLUSIONS : This study confirmed that speed-maintained standardization in road geometry is effective in reducing vehicle speeds, CO2 emissions, and noise levels. Moreover, there is further scope for the application of this method in the design of roads in urban and rural areas, as well as in the design of highways.

Although the rapid change from printed media to multi-media has yet to affect the primary goals and roles of the typography as means of information delivery, the new environment requires the typography to find a new direction. In other words, the typography, which has delivered the linguistic information only on the static surface, is urged to add the elements of time, music and technology to itself to fit such multi-media environments as monitors and screens. As a result, the typography changes into a complex concept allowing for expression of video and audio images. Recently, ADSL has been widely distributed with enhanced performances of PC, and thus, numerous multi-media data are distributed, but the majority of Internets and websites are full of texts. People can easily create texts and images, but not sounds because their tools are not efficient. Thus, as in the earlier age of film industry - just as in Chaplin's films - most websites and authoring tools serve the users with texts and figures only. In order to solve such a problem, the kinetic typography can be used to deliver the information effectively because it may help to deliver the sound information in the age of multi-media. With such basic conceptions in mind, this study was aimed at reviewing the structural relationship among visual motions, sound types and images in terms of combination of art and music. To this end, concept and characteristics of the kinetic typography and technological methods of inserting sound were examined.

Elevated Serum C-Reactive Protein as a Prognostic Marker in Small Cell Lung Cancer

홍수정,김대준,강영애,조병철 연세대학교의과대학 2012 Yonsei medical journal Vol.53 No.1

Purpose: Elevated C-reactive protein (CRP) is associated with poor prognosis in several tumor types. The purpose of this study was to investigate serum CRP as a prognostic marker in small cell lung cancer (SCLC). Materials and Methods: The pretreatment serum CRP level was measured in 157 newly diagnosed SCLC patients,and correlation between serum CRP level and other clinical parameters was analyzed. Multivariate analyses were performed to find prognostic markers using Cox’s proportional hazards model. Results: The initial CRP concentration was within the normal range in 72 (45.9%) patients and elevated in 85 (54.1%) patients. There was a significant correlation between serum CRP level and the extent of disease (p<0.001), weight loss (p=0.029) and chest radiation (p=0.001). Median overall survival (OS) in the normal CRP group was significantly longer than with the high CRP group (22.5 months vs. 11.2 months, p<0.001). Extent of disease (p<0.001), age (p=0.025), and performance status (p<0.001) were additional prognostic factors on univariate analysis. On multivariate analysis, elevated serum CRP level was an independent prognostic factor for poor survival (HR=1.8; p=0.014), regardless of the extent of disease (HR=3.7; p<0.001) and performance status (HR=2.2; p<0.001). Conclusion: High level of CRP was an independent poor prognostic serum marker in addition to previously well-known prognosticators in patients with SCLC.

Objective : The purpose of this study is to investigate the use of probiotics for cure of atopic dermatitis and suggest for the better method of studies in order to seek more effective treatment. Methods : We searched from Korean Traditional Knowledge Portal(KTKP), Reserach Information Sharing Service(RISS), National Discovery for Science Leader(NDSL) and PubMed. We selected among the papers published from 2005 to 2019 using terms related to ‘Atopic dermatitic & Allergy diseases & Probiotics’. Results : 41 papers were selected from the database worldwidely. In these collected 41 related theses, there were 14 experimental studies(34.1%), 16 clinical studies( 39.0%), 11 review studies (26.9%). 23 papers(76.7%) insisted that the effects is but 9 papers(30%) said not effective. Conclusion : The effects of probiotics in atopic dermatitis is investigated positively, however, we have to consider the methods to approach the result including the sort, amount of probiotics, how to culture, how to eat and so on.
