registration system were organized, computerized, and simplified. Especially the workers for the hospital registration desk were almost used computer all the working time. Therefore we assessed cumulative trauma disorder of registration desk workers related to computer use of general hospital. Methods: 62 women computer users who worked for registration desk of general hospitals in Busan were assessed from March to August, 2007. The workers were checked general characteristics(age, educational level, and marital status), work related characteristics, and symptoms by self-administered questionnaires. Results: Significantly decreased prevalences for cumulative trauma disorder were observed for subjects who had more educational level, the prevalence of cumulative trauma disorder was 69.2% among high school graduates, 38.2% among junior college graduates, and 20.0% among college graduates. Significantly increased prevalences for cumulative trauma disorder were observed for subjects who had more duration of computer use, the prevalence of cumulative trauma disorder was 56.5% for those who had used computer for more than 8 hours, 32.1% for those who had used computer for 4-7 hours, and 27.3% for those who had used computer for less than 3 hours. And Significantly increased prevalences for cumulative trauma disorder were observed for subjects who had more maximun daily computer use time without break, the prevalence of cumulative trauma disorder was 66.7% for those who had used computer for more than 7 hours, 38.1% for those who had used computer for 3-6 hours, and 21.7% for those who had used computer for less than 2 hours. Multiple logistic regression showed that subjects who had more maximum daily computer use time without break was more likely to report patient. Conclusion: Therefore these findings suggest that preventive interventions on hospital registration desk worker related to computer use were needed

촉매-크래킹에 의한 나프타로부터 경질 올레핀 제조기술

박용기,전종열,한상윤,김정리,이철위 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.5

세계적으로 에틸렌 생산공장에서 배출되는 이산화탄소의 양은 매년 141백만 톤에 이르며, 석유화학산업에서 소비되는 전체 에너지 중 약 40%는 나프타 스팀크래킹에 사용된다. 이로인한 지구 온난화를 막기 위하여 에너지 효율 증대를 통하여 이산화탄소 배출양을 최소화할 수 있는 나프타 크래킹 기술개발이 시급하다. 또한 천연가스로부터 얻어지는 에틸렌의 양이 점점 증가하기 때문에 프로필렌/에틸렌 비를 증대하기 위한 연구가 필요한 실정이다. 그러므로 에틸렌과 프로필렌 수요를 맞추기 위한 thermal cracking의 대안으로 촉매를 이용한 크래킹기술이 시도되고 있다. 본 논문에서는 나프타로부터 에틸렌, 프로필렌 등과 같은 경질 올레핀 제조에 관하여 지난 수 년간 공개된 특허와 실용화 가능한 공정 기술을 소개하고자 한다. In the whole world, the amount of CO₂ emission from the ethylene plant is about 141 million tons per year, and currently about 40% of the energy in petrochemical industry is used for steam cracking of naphtha. So, global warming issues have stimulated the development of new cracking process of naphtha which can minimize CO₂ emission through the increase of energy efficiency. Also there is an effort to increase the ratio of propylene/ethylene in naphtha cracking since the natural gas cracker which can produce ethylene preferentially increases more and more. Therefore, catalytic cracking of naphtha has been studied as an alternative of thermal cracking to balance ethylene and propylene demand and to reduce CO₂ emission. This paper will review the various routes which have been investigated and applied over the past years, hut will focus particularly on the recently patented and commercially demonstrated processes for the production of lower olefins from naphtha.

The purpose of this paper is to examine the effects of the changes in meat imports on marketing margins and producer's income share in Korean livestock industry. Theoretical analyses are based on Gardner's (1975) framework under the assumption of linear homogeneity of the production function and perfect competition both in output and input markets. His theoretical framework of the closed economy is extended by including foreign imports. Also, empirical study is conducted for beef and pork industries. The results show that the increase in import quota by 10 percent causes the domestic beef price to decline by 3.2 percent and the marking margins in this industry to increase by 16 percent with the elastic marketing services. In this case, the cattle producer's income shares reduce by 5.4 percent. For pork industry, domestic pork price declines by 0.9 percent as a result of 10 percent increase in imports. Also, the marketing margin for pork maeket increases by 3.9 percent, and hog producer's income share decreases by 1.3percent. The larger the supply elasticity of marketing services, the greater the marketing margin and the wider the extent that producer income share reduces. The results of this study indicates that marketing margins and producer's income shares are sensitive to the changes in the external economic environments in domestic meat markets such as imports. Some policy recommendations implied by this study can, therefore, be provided as follows. First, it is necessary for cattle producers to be supported by keeping calf production stable. Second, it is essential to make markets operate efficiently in order for the supply elsticities of marketing services to be less sensitive to the changes in imports.

Background : Diabetes mellitus is one of the common chronic disease in Korea. As most chronic diseases need continuous cares and behavioral controls, one of the effective managements for diabetes is maintenance healthy life style which is based on correct medical knowledge. So, we conducted this study to assess change of blood sugar levels and self-management behavior of diabetic patients following the case-management program enforced by National Health Insurance Corporation (NHIC). Methods : We conducted this study during the period from January 2006 to December 2006, 29 case managers performed the case management program for 672 diabetic patients in the districts of Busan, Woolsan, and Gyeongnam. We evaluated the effectiveness of the case management program based on the changes of blood sugar level, knowledge for diabetes and self-management behavior of diabetic patients. Data analysis was performed with t-test, paired t-test, McNemar X2-test and correlation analysis using SPSS program(ver 12.0). Results : After the case management program, smoking rate was reduced from 22.3% to 21.4% and exercise rate was increased from 65.0% to 80.2%(p<0.05). The knowledge standard of diabetics on 10-point scale revealed considerable increase from 6.05 before the management to 8.69 after the case management(p<0.05). All of diabetic self-management behaviors including nutrition management, self-test on blood sugar level, foot care, oral care and diabetic medication showed considerable improvement; the overall behavioral change, on a 5-point scale, improved from 3.25 to 3.75(p<0.05). The FBS level was improved from 138.4mg/dl to 131.5mg/dl and the blood sugar level 2 hours after a meal was improved from 203.7mg/dl to 183.5mg/dl(p<0.05). Conclusion : From the above results, we concluded that the case management program enforced by the NHIC showed positive behavioral changes on smoking and exercise, increased knowledge about diabetes as well as the level of nutrition management and also demonstrated decline of blood sugar levels. So, we need research of customized information for every patients rather than generally summarized information on diabetes and a self-dependent group formations for sustaining improved self-management after case management as well as development of education and training programs for case managers.
