  • Background : Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen in hospital-acquired infection, and is prevalent in intensive care units (ICU). The MRSA colonization rates of the nares and throat were examined in both the ICU and general ward. This study was performed to investigate the MRSA rate and necessity for MRSA screening cultures in patients admitted to ICU. Methods : Between June and September 2004, those patients admitted to both the medical ICU and general ward participated in this study. Bacterial cultures were performed on swabs of the nares and throat taken within 24 hours of admission. Clinical data were also collected. Results : One hundred and twenty one patients and 84 patients, admitted to the medical ICU and medical general ward, respectively, were investigated. The numbers of nasal MRSA colonization in the ICU and general ward were 3 (2.5%) and 3 (3.6%), respectively. There were 2 (1.7%) cases of throat MRSA colonization in the ICU, but none in the general ward. The MRSA colonization rates of the nares and throat were no different between the ICU and general ward. There were no significant differences in the previous admission, operation history and admission route between the ICU and general ward groups. Conclusion : The MRSA colonization rates of the nares and throat were 3.3 and 3.6% in the ICU and the general ward, respectively. The MRSA screening test does not appear to be required in all patients admitted to the ICU, but further studies, including high-risk patients, are recommended.

  • This study aims at improving Korea's competitiveness in port logistics through marketing strategy with integrating the conceptual approach into the empirical one and combining both the oldest military treatise and the newest evaluating model in social science that was applied by the HFP(hierarchical fuzzy process) model enhanced by the KJ method. The empirical results of this study show Busan in the middle among subject ports. At present, Korea plays a reciprocal role in the port market in East Asia, but in the medium- and long-term, Korea's ports will vie together with most major ports in the East Asian region. A descriptive investigation shows that Korea's developing tasks in port logistics must be considered in the context of the direction for developing port policies, the necessity of expanding port facilities in the capital region, securing the sufficient traffic volume through the establishment of the hinterland linking system and its positive utilization, and reforming the direction for developing the global logistics through increased port competitiveness. In the short- and medium-term, Korea must use the opportunity factor of 'Growth and open door policy of China' as a geoeconomic advantage and to utilize Korea's ports as a gate to Chinese foreign trade. With the rise of China's economy, China also plays a significant role in both port and airport markets. Hence, the linking system between the two must be established to meet the expanding traffic volume, especially in the capital area. Moreover, it is necessary for Korea to secure port logistics through the establishment of the hinterland linking system and its positive utilization. The great accomplishment of this paper is to present strategies to increase Korea's port competitiveness in the rapidly changing environments of world logistics with the focus on both the oldest military strategic treatise and the newest empirical method in social science. In order to reinforce this study, it needs further compensative research because the evaluation structure could be subdivided with more extensive and precise criteria.

  • While the second and the third industrial revolutions made it possible a few standardized designs to be extracted and produced in large quantities, the recent development of the 3D printing technology allowed many individuals to reflect their unique personal characteristics on their creative works and produce them in large quantities-i.e., personally customized designs and mass production of various designs. However, for the customized designs and the mass production of various designs through the 3D printing technology, the individuals should use a 3D modeling software and the supporting features of the software can significantly affect the type and shape of a creative work. In this study, we surveyed the individuals who design the creative works using 3D printers about the type of software that they use and the type of creative works that they design using the software, to propose a possible direction of new software that supports their activities. To do this, we first surveyed sixty members of the OpenCreators, which is the largest 3D printing creator community in South Korea, about the 3D modelling Software that they use for their 3D printing creations, the best 3D modelling software for the 3D printing, and the type of frequently printing creation using the best 3D modelling software. We then analysed the response results. As a result, we found that most of 3D printing creators in South Korea use Rhino and 123D Design. More specifically, the Rhino was being widely used by the people in the 3D printing industry to print prototypes, samples, and mock-ups, while the 123D Design was being mainly used for general purposes such as educational tools, accessories, and home interior accessories. Therefore, we believe it is necessary to develop the software in two separated categories, i.e. for the business, like the Rhino, and for the beginners, and educational and personal purposes, like the 123D Design. Finally, we stressed and proposed the necessity to support individual creators by developing an industry-specific 3D modeling software.

  • To increase the intake of calcium in elementary school children, 20 high calcium dishes (HCD) were developed. The pictures of HCD with the calories, calcium content, and the price per serving were given for the evaluation of HCD to 118 school dietitians. Along with the evaluation, a questionnaire concerning the perception on calcium nutrient and calcium fortified foods (CFF), the use of school milk and CFF, and the need and their endeavor for HCD was administered. Over 90% of subjects were aware of the importance of calcium in school lunch menu and 80% of them recognized the necessity for exploring HCD, though their endeavor remained at a 30% level. HCD that reached the requirement of calcium for the school lunch was 3 and the preference response over 4 (maximum 5) was 2 HCD with better acceptance by younger subjects. 70.3% of subjects were aware of CFF and their response on them were diverse as a positive conception 42%, negative 33% and willing to use 40%, not to use 40%. The dietitians who provided school milk or willing to develop HCD were more positive to use CFF. These results indicate that school milk is the most important calcium source and further pursue for HCD and CFF is needed to achieve the calcium requirement for the elementary school lunch.

  • Purpose : To establish and verify the proper and the practical IMRT (Intensity--modulated radiation therapy) patient QA (Quality Assurance). Materials and Methods : An IMRT QA which consists of 3 steps and 16 items were designed and examined the validity of the program by applying to 9 patients, 12 IMRT cases of various sites. The three step OA program consists of RTP related QA, treatment information flow QA, and a treatment delivery QA procedure. The evaluation of organ constraints, the validity of the point dose, and the dose distribution are major issues in the RTP related QA procedure. The leaf sequence file generation, the evaluation of the MLC control file, the comparison of the dry run film, and the IMRT field simulate image were included in the treatment information flow procedure QA. The patient setup QA, the verification of the IMRT treatment fields to the patients, and the examination of the data in the Record & Verify system make up the treatment delivery QA procedure. Results : The point dose measurement results of 10 cases showed good agreement with the RTP calculation within $3\%$. One case showed more than a $3\%$ difference and the other case showed more than $5\%$, which was out side the tolerance level. We could not find any differences of more than 2 mm between the RTP leaf sequence and the dry run film. Film dosimetry and the dose distribution from the phantom plan showed the same tendency, but quantitative analysis was not possible because of the film dosimetry nature. No error had been found from the MLC control file and one mis-registration case was found before treatment. Conclusion : This study shows the usefulness and the necessity of the IMRT patient QA program. The whole procedure of this program should be peformed, especially by institutions that have just started to accumulate experience. But, the program is too complex and time consuming. Therefore, we propose practical and essential QA items for institutions in which the IMRT is performed as a routine procedure.

  • The objectives of this study was to analyze the major causes of decreasing utilization rate of health care institutios in pilot-project area of regional medical insurance, Kwang-hwa and Kun-wi country. After the implementation of medical insurance, utilization rate of health institutions turned out' to be lower than it was estimated, when the pilot-project of regional medical insurance was planned. It might be due to changes in inhabitant's behavioral attitude toward medical insurance. So this study was made to find measures for financial stability by increasing utilization rate of health care institutions and to be available for basic demand-supply program of medical care. The hypothesis of this study was as follows; First. there is difference in understanding health care institutions between Kun-wi and Kwang-hwa. Second. respondesnts of inquiry survey have exact knowledge of their past experience of treatment taken prior to enforcement of medical insurance, Questionaire survey was made as to each 700 household among total 11, 884 households in Kun-wi and 20,919 households in Kwang-hwa. In case of Kun-wi, 70% of inquired households (491) gave their answers. In Kwang-hwa, the number was 560 households (80% of inquireds). Dollected data was processed and analyzed by way of using SPSS batch system. To evaluate facto rs distribution aspects of data and to make comparison between two area, percentage and $X^2$ distribution were applied. The results were as follows; L The utilization rate of health care institutions in Kun-wi and Kwang-hwa was lower than it was estimated. when pilot-project of medical insurance was planned. 2. Prior to the implementation of medical insurance. inhabitants in two area chose the medical institutions considering such factors. First was medical care fee cheap. second in habitant's residence, Third was the institutions conveniently easy of access. 3. After the implementation of medical insurance. 26.1% of inqurieds in Kun-wi and 41.6% in Kwang-hwa, changed medical institutions. In case of Kwn-wi, from health care institution (p 0.05), and in case of Kwang-hwa, vice versa, from general medical institutions to health care institutions. 4. Evaluation by factors were made such as follows. Inquired gave high marks to following facts: In case of Kun-wi, general medical institutions were difficult of access and relation between patients: was not friendly, but burden of medical expenditure was light. Effects of treatment and facilities was good. In case of Kwang-hwa, inquired gave high evaluation marks to the follow ing facts; facilities of medical institutions was not good, but the burden of medical expenditure was light. 5. After the implementation of medical insurance, the services was evaluated as good, but inquired hopec for lessening the burden of medical expenditure. 6. In case of exact understanding of cost-sharing, the evaluation rate in Kwang-hwa was higher than that of Kun-wi (p < 0.005). And positive attitude toward necessity of medical insurance was also good in Kwang-hwa (p < 0.05). 7. In case of inquired's attitude toward medical institutions, Kwang-hwa showed positive response (p < 0.05) 8. In the case of comparison between general medical institution and health care institution, two area showed similar positive response; medical manpower, facilities of medical institutions and effest: of treatement was good. 9. In comprehensive evaluation of benefit-service; the general medical institution's positiveness was higher than that of health care institutions in Kun-wi. But in Kwang-hwa vice-versa. 10. If the medical expenditure of general medical institution and health care institutions was equal 77% of inquireds in Kun-wi and 59.1% in Kwang-hwa answered that they chose general medical insurance. Considering results above mentioned, the conclusion of this study was made as follows. 1. In Kwang-hwa county, where the understanding of health care institutions's was good, the utilization's of health care institutions was shown high. Therefore, in case of Kwang-hwa, betterment: should be made to induce increasing utilization rate for negative factors of health care institutions. 2. In case of Kun-wi, where the understanding of health care institutions was on the decrease, measures for changing such negative factors should be taken by way of strengthening public relations. And cases of Kwang-hwa should also be studied. 3. On the side of financial stabilization and establishing health care delivery system, primary health care should be available. Therefore, the major cause of inhabitant's avoiding health care institutions should be known. And measures for activating that institutions have to be taken. So, the facilities of health care institution have to be improved up to the level of clinic. And supportive measures for securing equipment and improving health care services should also be taken. It is necessary that strategy for public relations should be employed with policy considerations and supports.

  • The purpose of this study was to provide the basic resources for developing a parish nursing program. We did this by investigating what demands were made on the parish nursing service by the parishes or churches under review. The subjects of this study were 96 pastors located throughout the City of Busan. NP (New paragraph) $\gg$ We conducted our research by utilizing a modified version of the study created by Hwang (2000) and by using the help of prior research and professionals gathered from the parish nurse questionnaire by Djupe (1990). The data in this study were collected from July 1 to Oct. 31, 2001, using the questionnaire method. The Data were analyzed by: (a) frequency: (b) percentage: (c) mean: (d) standard deviation, and x^2-test$ with SPSS/PC program. The study has found the follows: 1. For subjects making demands on the parish nursing service, 95.8% were in need of using the services of parish nurses. On the demands of parish nursing service for the subjects, 95.8% the necessity of parish nursing services. And they answered by their intention of asking for parish nursing service practice. 2. Of the subjects under review, 71.9% were part-time workers and 28.1% were full-time employees 71.9% of part time and 28.1% of full times duty. In terms of the method of pay for work, 41.8% were pay free or freelance while 51.2% were on salary. And engagement intention of parish nurse as preacher was 88.5%. 3. The demand for nursing services in various categories were as follows. (a) hospice care: (4.02 1.11), (b) health screening: (3.98 1.09), (c) home visiting: (3.97 1.16), (d) group health education: (3.81 1.12), (e) organization of volunteer groups: (3.75 1.12), (f) individual health education: (3.75 1.14), (g) advice on choosing hospital or hospital consultation: (3.69 1.21) and (h) individual counseling: (3.51 1.31). 4. In terms of the specific services rendered by parish nurses. our study found that services were needed for the following: physical symptom management; preparation before death in spiritual preparation for death, blood pressure check in health examination, home visiting where the patient makes phone call, management of chronic disease in group health education, disease management in individual health education, advice on choosing hospital, or hospital consultation: and physical problems in individual counseling. 5. With respect to whether there was a correlation between what church a pastor came from and the types of demands made, there was NO significant difference found. 6. In relation to the characteristics of the subjects and their church and the hope demands (duty pattern and method of payment and engagement intention of parish nurse as preacher) for parish nurses, these had non significant differences. In conclusion, the perception of parish nursing service is very high. Moreover, we found that there is a great demand for well ordered parish nursing services to promote the health of each congregation. Before doing so, it would be better to make things known and to consider the relevant characteristics shown in the researched results.

  • Background: There have been controversies whether mitral valvular surgery is necessary in the patients with moderate ischemic mitral regurgitation undergoing coronary artery bypass grafting. The purpose of this study is to evaluate the long term clinical results of patients with moderate ischemic mitral regurgitation. Material and Method: Between January 1992 and February 2005, 44 patients with moderate ischemic mitral regurgitation underwent coronary artery bypass grafting. Concomitant mitral valvular procedure was performed in 20 patients (group 1) and isolated coronary artery bypass grafting was performed in 24 patients (group 2). There were no significant difference between groups except cardiopulmonary bypass time (p<0.01). Postoperative follow up duration was $30.1{\pm}29.6$ months and last follow up echocardiographic examination was performed at $21.2{\pm}28.0$ months. Result: There was no difference in operative mortality between groups (group 1 vs group 2, 15.0% vs 8.3%, p=0.493). Grade of mitral regurgitation ${(0.81{\pm}0.91\;vs\;1.50{\pm}0.05,\;p=0.046)}$ and reduction in regurgitation grade ${(1.75{\pm}0.93\;vs\;0.70{\pm}1.26,\;p=0.009)}$ were different between two groups. But there were no significant differences in left ventricular ejection fraction ${(34.1{\pm}11.4%\;vs\;41.6{\pm}12.9%)}$, left ventricular end systolic volume ${(118.2{\pm}63.9\;ml%\;vs\;85.6{\pm}281\;ml)}$, New York Heart Association functional class ${(2.1{\pm}0.2\;vs\;2.4{\pm}1.2)}$ and 5 year survival rate ${(85{\pm}8%\;vs\;82{\pm}8%)}$. There was no risk factor for operative mortality and the only risk factor for late death was preoperative atrial fibrillation (p=0.042). There was no significant correlation between mitral valvular surgery and late death. Conclusion: Concomitant mitral valvular procedure in patients with moderate ischemic mitral regurgitation undergoing coronary artery bypass grafting had no significant positive effect on survival and ventricular function compared with isolated coronary artery bypass grafting. Prospective randomized study may be needed to evaluate the necessity of concomitant mitral procedure and to find more effective method for the improvement of ventricular function.
