This study was performed to investigate the level of importance and performance of patient education perceived by patients and nurses. The subjects consisted of 108 patients and 106 nurses in one university-affiliated hospital in Daegu, from February 1 to February 5, 2002. Data were collected through self-report questionnaires which were constructed to include the level of importance and performance of patient education. The data were analyzed by an SPSS program. 1) The level of importance of patient education perceived by patients and nurses was high, but the level of performance of patient education was relatively low. The level of importance and performance of patient education perceived by patients and nurses ranked as the highest in the area of diagnosis and treatment. 2) The level of importance and performance of patient education perceived by patients was not different according to general characteristics. The level of importance and performance of patient education perceived by nurses was different according to age and the working unit and the level of performance of patient education was different according to clinical career and job position. These results suggest that the level of importance of patient education perceived by patients and nurses was different to the level of performance of patient education perceived by them. Therefore nurses should actively provide patients with the educational program based on the importance of patient education perceived by patients.

Purpose: To provide legislative data for the amendment of Article 36 of the Emergency Medical Service Act on the qualifications of emergency medical technicians. Methods: The study was drafted based on the Emergency Medical Service Act; data on the emergency medical technicians (EMT) system and curriculum in Korea, United States. Japan, and Taiwan; and previous studies on the EMT system in Korea. Results: The length of education. work scope. amd role of level 1 EMTs vary significantly depending on the type of qualifications they have as emergency medical professionals, while the supply of level 1 EMTs has already reached a point of saturation. Accordingly, the current regulation on allowing level 2 EMTs with at least three years of experience to take the level 1 EMT test presents serious inequity for students just graduating from their emergency medical services program. It is also a factor that degrades the professionalism of level 1 EMTs. Conclusion: Article 36, paragraph 2. subparagraph 3 of the Emergency Medical Services Act pertaining to regulations on "EMTs who have worked as level 2 EMTs for at least 3 years" needs to be removed.

Monocyte chemoattractant protein-1 (MCP-1) plays an important role in cardiovascular disease (CVD). Genetic polymorphism in the regulatory regions of MCP-1 could affect MCP-1 expression. The purpose of the study was to explore the possible association of MCP-1 -2518 A/G genetic polymorphism and CVD risk factors in the elderly Korean population. Dietary, anthropometric, and biochemical factors were assessed in 168 subjects. The frequency of A/A, G/A, and G/G genotypes was 14.2%, 45.8%, and 40.0%, respectively. The blood level of MCP-1 was significantly higher in subjects with A/A genotype. The MCP-1 level was significantly higher in A/A genotype with hypercholesterolemia than in other genotypes. Meat intake and percent energy from lipids were significantly positively correlated with the MCP-1 level, especially, stronger in A/A genotype. In the stepwise discriminant analysis, TNF-${\alpha}$ level, meat intake, HDL-C were associated with MCP-1 in all subjects (model $R^2=24%$). TNF-${\alpha}$ level, sugar intake, cholesterol intake, and meat intake affected MCP-1 in A/A genotype (model $R^2=82%$), but not in G/A or G/G. In conclusion, subjects possessing A/A genotype exhibited higher levels of MCP-1 than other genotypes in Korean elders. Further, meat, sugar, and cholesterol intakes affected the MCP-1 level. Therefore, the decrement of meat, sugar, and cholesterol intakes helps to normalize the MCP-1 level and can decrease CVD risk in A/A genotype.

The purpose of this study is to evaluate the level of fixed assets management of the factors affecting its management level. The surveyed data were gathered from 105 general hospitals among 263 general hospitals nationwide. The level of fixed assets management was measured by 11 dimensions of assets management. The results were as follows : 1. According to general characteristics of hospitals, the management level of public hospitals and corporatized hospitals was better than that of private hospitals. The management level was better as increasing beds. 2. In the structural characteristics of assets management, the management level of the hospitals which had the responsible person for assets management was better than that of the hospitals which had not. 3. In the operating characteristics of assets management, the hospitals that conducted education for the job had better level of assets management that did not it. The hospital that the discard of assets was decided by engineering department or management department were better in management level than the hospitals that it was decided by user department. The management level of hospitals which were computerized for assets management was better. 4. In the full model, the most factors affecting the level of assets management were the factors that were characterized by operation pattern of assets management, and the operating characteristics of assets management were explained to 23.1% of total 45.7%. Conclusively, the level of assets management was mostly affected by the operating characteristics of assets management which were education for the job, discard decision not by user department, computerization for assets management. Therefore, hospitals perform education of the job, discard decision by engineering or management department, and computerization for better level of fixed assets management

The purpose of this study is to redesign a letter sorting station and to present the optimal work-space through the ergonomic analysis of the sorting station for reducing the 'Work-Related MusculoSkeletal Disorders(WMSDs)'. We surveyed the work environment in terms of the reason causing WMSDs. According to the survey results, Deltoid on the arm, Trapezius on the shoulder and Erector Spinae on the waist are most frequent attacking parts. Accordingly, We classified sorting stations by the horizontal work-space(Level 1, Level 2, Level 3) and the vertical work space(Level 1, Level 2) based on the criteria of ergonomic optimal work-space. In addition we improved the sorting station through investigation and analysis of the work-load regard the each defined work-space. In order to analyze the effect of the horizontal and vertical work-space, subjects carried out simulated sorting tasks. Each level(Level 1, Level 2, Level3) of the horizontal work-space is significant regarding each muscles(the shoulder, arm and waist), and each level(Level 1, Level 2) of the vertical work-space is significant regarding the arm and waist, but not shoulder. Finally, we founded the difference of work-load according to the work-spaces. Then, it is necessary to improve the work-space causing the high work-load(Level 3 of the horizontal work-space). Then, this study presented the specification of a sorting station which is suitable to the korean body size, and constructed the 3D shaped model of the stations by the ergonomic analysis.

The purpose of this study was to investigate the nutritional status of antioxidant vitamins in relation to serum malondialdehye(MDA) level in postmenopausal women with common occurance of cardiovascular disease(CVD). Data about general characteristics including smoking, drinking and exercise status, dietary intake and serum level of antioxidant vitamins, and serum MDA level were collected from eighty-five postmenopausal women. Mean serum MDA level was 1.62$\pm$0.03nmol/ml, and general characteristics and serum lipid profiles were not significantly different among the three group: low MDA(<1.45nmol/ml), midium MDA(1.45-1.74nmol/ml) and high MDA($\geq$1.74nmol/ml). Total mean vitamin A intake was 472.8$\pm$37.7RE, 68% of RDA, vitamin C intake was 134.3$\pm$8.7mg, 192% of RDA and vitamin E intake was 8.6$\pm$0.5mg, 86% of RDA for Korean. In takes of antioxidant vitamins from the diet were not significantly different among the three groups. However significant negative correlation(r=-0.242, p<0.05) was observed between vitamin E intake and serum MDA level in total subjects. Total mean serum vitamin A, $\beta$-carotene and vitamin C level were 0.59$\pm$0.01$\mu\textrm{g}$/ml, 0.25$\pm$0.01$\mu\textrm{g}$/ml and 9.02$\pm$0.28$\mu\textrm{g}$/ml, respectively. Total mean serum vitamin E and vitamin E/total cholesterol level were 9.15$\pm$0.42$\mu\textrm{g}$/ml and 4.09$\pm$0.17$\mu\textrm{g}$/mg, respectively. Serum antioxidant vitamins levels were not significantly different among the three groups. However serum vitamin C and E level were negatively correlated to serum MDA level. We can conclude that it will be helpful for postmenopausal women with common occurance of CVD to improve nutritional status of antioxidant vitamins by increasing intakes of antioxidant vitamins, especially vitamin C and E.
