자연친화적인 급내리막 직선부에서 GHG 배출지표에 근거한 속도유지표준화 형태의 교통정온화
홍수정,오흥운 한국도로학회 2016 한국도로학회논문집 Vol.18 No.2
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.

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.
