Objectives : Both organized and opportunistic screening programs have been widely used in Korea. This paper examined the determinants of the use of opportunistic screening programs in Korea. Methods : The subjects were a national stratified random sample of 10,254 people aged 45 or older from the first wave of the Korean Longitudinal Study of Ageing in 2006. A logit model was used to examine the determinants of the use of opportunistic screening programs in terms of the demographic and socioeconomic characteristics, the type of health insurance and the health status. Results : Thirteen point seven percent of the individuals received opportunistic screening programs within 2 years from the time the survey was conducted in 2006. The individuals who graduated from college or who had even more education were 3.0 times more likely to use opportunistic screening programs compared with the individuals who were illiterate. The individuals who resided in urban areas and who had religious beliefs were more likely to receive opportunistic screening programs compared with their counterparts. Those who were in the first quartile for the total household assets were 2.6 times more likely to use opportunistic screening programs than those who were in the fourth quartile for the total household assets. Privately insured people were 1.6 times more likely to use opportunistic screening programs than those who were not insured. Finally, the individuals who self-assessed their health status as worst were 2.1 times more likely to use opportunistic screening programs compared individuals who self-assessed their health status as best. Conclusions : This study suggests that opportunistic screening programs can be an indicator for whether or not an individual is among the advantaged group in terms of their socioeconomic characteristics and type of health insurance.

강성욱,장재훈,이재원,김대영,신영진,Kang, Sung-Wook,Chang, Jaehoon,Lee, Jae-Won,Kim, Dae-Young,Shin, Young-Jin 한국터널지하공간학회 2021 한국터널지하공간학회논문집 Vol.23 No.5

Railway projects have been consistently increasing in Korea. In relation to this trend, the mechanized tunneling using Tunnel Boring Machine (TBM) is preferably applied for mining urban areas and passing under rivers. The TBM tunneling under difficult grounds like mixed faces with high water pressure could require ground improvements for stable TBM advance or safe cutter head intervention (CHI). In this study, pre-grouting works for CHI in Daegok-Sosa railway project are presented in terms of the grouting zone design, the executions and the results, the lessons learned from the experience. It should be mentioned that the grouting from inside TBM was carried out several times and turned out to be inefficient in the project. Therefore, grouting experiences from the surface are highlighted in this study. Jet grouting was implemented on CHI points on land, while permeation grouting off shore in the Han River, which mostly allow to access the cutter head of TBM in free air with stable faces. The results of CHI works have been analyzed and the lesson learned are suggested. 철도망 구축이 확대되는 추세 속에 도심지나 한강을 통과하기 위해 TBM 굴착공법 적용사례가 증가하고 있다. 특히, 도심지나 한강하저를 통과하는 경우 불량한 지반 및 지하수조건을 조우하게 되며 안정적인 굴진 및 커터교체(Cutter Head Intervention, CHI)를 위해서 그라우팅을 적용하고 있다. 본 논문에서는 TBM 굴착공법을 적용한 철도 터널 시공 시 적용한 그라우팅에 대하여 소개하고자 한다. 특히, CHI를 위해 그라우팅을 수행한 사례에 대한 소개나 분석이 많지 않은 것으로 판단하여 CHI를 위한 그라우팅 범위산정, 수행결과, 고찰 및 제언(Lessons Learned)을 기술하고자 한다. 그라우팅은 막장안정성을 확보하는 목적이 있으며, 작업위치에 따라 지상(수직)그라우팅과 TBM 장비 내에서 수행하는 갱내 그라우팅으로 나눌 수 있다. 갱내그라우팅을 수행한 결과 공기 및 보강효과 측면에서 지상(수직) 그라우팅에 비해 비효율적이라고 판단되어 지상그라우팅으로 계획을 변경하였다. 한강하저 구간의 경우 슬러지 발생으로 인한 환경오염, 주입재 유실 등이 우려되어 고압분사그라우팅을 적용할 수 없었으며 대안으로 수중불분리 주입재를 적용한 저압그라우팅을 적용하였다. 육상구간은 지상 작업부지를 확보할 수 있어 고압분사그라우팅을 적용하였다. 실제 그라우팅을 수행한 결과를 소개함으로써 향후 쉴드 TBM을 적용한 터널 시공 중 CHI 시 지반조건에 따른 적합한 그라우팅 공법 및 방법을 결정하는데 기초자료로 활용될 수 있을 것으로 기대된다.

강성욱(Sung Wook Kang),전성찬(Sung Chan Jun) 한국HCI학회 2009 한국HCI학회 학술대회 Vol.2009 No.2

Brain Computer Interface (BCI) is a communication pathway between devices (computers) and human brain. It treats brain signals in real-time basis and discriminates some information of what human brain is doing. In this work, we develop a EEG BCI system using a feature extraction such as common spatial pattern (CSP) and a classifier using Fisher linear discriminant analysis (FLDA). Two-class EEG motor imagery movement datasets with both cued and uncued are tested to verify its feasibility.

The purpose of this research was to investigate factors affecting the level of job satisfaction of radiologic technologists who are working at hospitals. This research has been achieved by self-administered questionnaires of 263 radiologic technologists from the 26 hospitals which were located in Gyeongbuk province from March 15th to April 5th, 2011. The questionnaires consisted of general characteristics, job-related characteristics, environmental variables, psychological variables, structural variables and job satisfaction etc. The average score of job satisfaction was 3.21. Those who had a religion or when the present job agreed with the desired job, the job satisfaction was higher(p<0.05). The average score of environmental, psychological and structural variables were each 3.02, 3.28, and 3.08. The associated factors with the higher score in environmental variables were younger age, unmarried, when the duration of working in present hospital was lower than 5 years or the present jobs agreed with the desired jobs(p<0.05). In psychological variables, those who had higher score were man, higher education, with religion, higher income, or when the present jobs agreed with the desired jobs were high(p<0.05). In structural variables, those who had higher score were older age or higher income(p<0.05). The statistically significant variables of multiple regression analysis associated with job satisfaction were religion, psychological variables, and structural variables. As a result, understanding of professional job, pride in the job and providing opportunities that they can show their abilities should be considered to have high level of job satisfaction.
