In radiology department, where patients with a variety of diseases receive their tests, there is a large possibility of cross contamination of nosocomial infection. Magnetic resonance imaging (MRI) tests take particularly more time than other tests do, which increases the possibility of being exposed to cross contamination. Therefore, this research examines the status of MRI equipment sterilization and investigates the bacterial distribution on head coils, which have the most frequent contact with patients, patient fixation blocks, and bores, which are confined spaces. The status of MRI equipment disinfection was examined by a survey targeting 150 employees, and the distribution of bacteria was measured in ten medical facilities. The result of bacterial distribution tests on MRI equipment showed various bacteria, including Staphylococcus, Acinetobacter, Sphingomona, Pantoea agglomeranss, Micrococcus, Bacillus, Saprophyticus, Brevundimona, and Myroidesspecies. The result of examining the stat us of MRI room disinfection showed that the disinfections of the head coil, block, and bore were implemented well, and the largest proportion was carried out once a day in the morning. The time and implementation of disinfection by the disinfection manager showed that they were implemented well when the manager was the MRI room examiner. The disinfection after examining a patient using an appropriate disinfectant is mandatory to prevent cross contamination.

It is to establish preliminary data about healthcare convergencr of infection control by performing a bacterial contamination test for CT scanner as well as general radiographic systems in the emergency rooms of general hospitals. The period was December 1 ~ December 31, 2015. It is detect in the emergency rooms of 7 medical facilities including 2 in Seoul, and 1 in Gyeonggi-do Province, and 2 in Jeonla-do Province, and 2 in Chungcheong-do Province. The surface contamination strains detected from CT scanner in the radiology department emergency rooms were Micrococcus species(4,5%), Stenotrophomonas maltophilia(9%), Enterococcus faecium(4.5%), Providencia stuartii(4.5), and Gram negative bacilli(4.5%). Also, the surface contamination strains detected from general radiographic system in the radiology department emergency rooms were Providencia stuartii(11%), Klebsiella pneumonia(3.5%), Stenotrophomonas maltophilia(11%), Pantoea species(11%), Acinetobacter baumannii(3.5%), Micrococcus species(3.5%), Escherichia coli(3.5%), Enterobacter species(3.5%), and Gram negative bacilli(11%). Considering that the regions of most detection were all the places closely related to patients, radiologists would have to thoroughly clean with alcohol before and after a test.

Objective: This study aimed to compare the characteristics of humidifier disinfectant-like products (HD-like products) and humidifier disinfectant products (HD products) and introduce actual cases of the usage of HD-like products in hospitals based on an on-site investigation. Methods: The characteristics, chemical components, and usage of HD-like products (Hichlor or Biospot) and HD products (N-with) containing NaDCC (sodium dichloroisocyanurate) were compared. In the process of conducting the on-site investigation, four hospitals were identified as previously using HD-like products. Each on-site investigation to identify the use of HD-like products was composed of four parts: 1) hospital infection control guidelines, 2) manual for humidifiers in patient's rooms, 3) interviews with nursing staff, infection managers, and purchase managers, 4) searching on the product purchase system. Results: Although HD-like products (Hichlor and Biospot) and HD products (N-with) were sold for different usage purposes, they were all white-colored and coin-shaped foaming tablets with the same chemical component, NaDCC. The manual for using HD-like products and HD products was similar (inserting the tablet in a humidifier container with water). Among the four hospitals, one had used Hichlor in the same manner as HD (N-with) by inserting a tablet in 1L of water in a filled humidifier container and Biospot as a kind of detergent for humidifier container cleaning. Another two hospitals had used Biospot and/or Aniosyme as a kind of detergent for humidifier container cleaning. The other hospital had used unknown product in the same manner as N-with, so we thus assumed it was either an HD products (N-with) or HD-like products (Hichlor, Biospot). Conclusion: This study raises the possibility of the development of adverse health effects similar to exposure to an HD-products when exposed to an HD-like products and the possibility of further use in other medical institutions or multi-use facilities. Therefore, an expansion of the investigation is needed in order to confirm whether there have been similar cases in the past.

This was preliminary study that was to find out the developing point in military meal service to focus on seafood dishes that recently increased plate waste. This study was conducted to analyze menu patterns in military meal service. The result of this study was using to develop new seafood dishes in military meal service. On the basis of some findings, several developing points how to plan meals include many kinds of seafood dishes and to modify taste and cooking method that was more highly prefered by young military persons were suggested. This preliminary study findings were as follows: 1. Each meal was served cooked rice and 4 kinds of dishes(soup or stew, main dish, side dish and kimchi) 2. The seafood dishes was served as 28.6% in soup or stew, 35.0% in main dish and 36.4% in side dish of total serving of seafood dishes. 3. All of raw materials of seafood were supplied by frozen, several items were supplied dried material. Supplying seafood items were limited. Numbers of using seafood items were using 2.7 times per day. Laver and squid was most frequently used. 4. Seafood dishes were frequently serving in breakfast, especially seasoned & toasted laver was served 28.8% of seafood menu in breakfast because of convenience. 5. The nutrients contents of each dishes were as follows, the soup was $86.5{\pm}3.2kcal$ and $10.9{\pm}8.9g$ of animal protein, stew was $165.3{\pm}70.2kcal$ and $13.3{\pm}7.9g$ of animal protein. Nutrients content of other main dish and side dishes was different from 108.1kcal (in steaming dish) to 412.4kcal (in deep-fat frying dish) according to different cooking method. The highest animal protein dish that contented $18.9{\pm}5.1g$ of protein was pan-frying dish or grilling dish. Lowest one was $8.4{\pm}4.9g$ in braising dish. 6. Major cooking method of seafood was stew and the next was deep fat frying, stirfrying and braising. Pan-frying or grilling was seldomly used in military menu because of limitation of kitchen facilities and cooking utensils. On the basis of these findings, newely developing military seafood menus were focused on combination dish(such as seafood cooked rice or seafood fried rice) and many kinds of sauce that was applied to deep-fat frying dishes.

The objective of this study was to examine the impact of changes in maternal age and parity distribution on birth weight. The study population included 7,786 single live births in 1977 and 8,671 single live births in 1987 delivered at 9 medical facilities in Pusan. Data were obtained from the delivery record. The proportion of infants born to the mothers of 25-29 years increased from 56.475 in 1977 to 65.1% in 1987 and the proportion to the mothers of 30-34 years increased from 18.8% in 1977 to 21.6% in 1987. In the same period, the proportions of 1st and 2nd birth order were increased from 56.9% and 28.8% to 59.9% and 36.8%, respectively. The proportion of infants born to the age group of ${\leq}24\;and\;35{\leq}$ years were decreased in 1987. The proportion of births of the third or higher birth order was decreased from 14.2% in 1977 to 3.3% in 1987. Low birth weight (<2500gm) incidence rate was 5.3% in 1977 and it was decreased to 4.0% in 1987. It was estimated that changes in maternal age-parity distribution accounted for 10.7% of the decreased in low birth weight incidence rate. Rest of the change (89.3%) was attributed to the reduction of age-parity specific low birth weight incidence rate. Application of the direct adjustment method was considered to be an adequate tool for evaluating the impact of family planning on neonatal health.

In the conduct of this study, a web-enabled healthcare system for the management of hypertension was implemented through a hyperlink-based inference approach. The hyperlink-based inference platform was implemented using the hypertext capacity of HTML which ensured accessibility, multimedia facilities, fast response, stability, ease of use and upgrade, and platform independency of expert systems. Many HTML documents, which are hyperlinked to each other based on expert rules, were uploaded beforehand to perform the hyperlink-based inference. The HTML documents were uploaded and maintained automatically by our proprietary tool called the Web-Based Inference System (WeBIS) that supports a graphical user interface (GUI) for the input and edit of decision graphs. Nevertheless, the editing task of the decision graph using the GUI tool is a time consuming and tedious chore when the knowledge engineer must perform it manually. Accordingly, this research implemented an automatic generator of the decision graph for the management of hypertension. As a result, this research suggests a methodology for the development of Web-enabled healthcare systems using the hyperlink-based inference approach and, as an example, implements a Web-enabled healthcare system for hypertension, a platform which performed especially well in the areas of speed and stability.

This study was conducted to examine health behaviors in hypertensive patients and the factors that would affect these healthy life-styles. and to provide basic data for effective and continuous hypertension control in private medical facilities. Among those patients diagnosed as hypertension who had visited the Department of Internal Medicine of Yeungnam University Hospital during the two month period from August 2 to September 30, 1999, the present study included 222 patients who were in more than one month after the initial diagnosis of hypertension and those who had hypertension for less than 10 years. Using a structured questionnaire, the present study was conducted by a self-administered survey method, and the obtained data were analyzed with t-test, $x^2$-test and one-way analysis of variance using the SPSS statistical program. The scores on knowledge related to hypertension were higher as the education level of a patient was higher(p〈0.05). As for occupation, those who performed office or management jobs showed higher scores than those who were into manufacturing jobs, and as for economic status, although those patients who were in middle class showed highest scores, however, no statistical significance was observed. The scores of knowledge on hypertension was higher when the family history of hypertension was present(p〈0.05). The scores of health-related behaviors were higher with higher education level and higher economic status, higher in those with family history of hypertension, and higher in those with office or management jobs than those who had manufacturing jobs(p〈0.05). Blood pressure measurement on regular basis was performed most frequently in those who were between 50-59 years old with 83.3% and was least frequent in those who were older than 70 years old with 50%(p〈0.05). The frequency of regular blood pressure measurement was higher with higher education level, higher economic status, higher in those with family history of hypertension, and the highest in those with management position with 93.5%, however, on statistical significance was observed. Changes in health-related behaviors after hypertension diagnosis were higher with higher education level, higher economic status, and in those patients performed office or management work. In particular, diet change was observed in female and higher economic status and smoking cessation was observed in 60-69 years old. Housewives and office workers or managers have taken exercise more regularly and those who had management jobs and had high scores on knowledge related to hypertension would participate health education program more actively. Thus, for improving health-related behaviors for continuous management of hypertension, changes in health-related behaviors can be followed through conduction health education to improve understanding of knowledge related to hypertension as the method of helping to improve changes in health life-styles in those with little education and those in low economic status.

This study examined the relationship between the physical activity levels and health care utilization in Korean elderly based on the data from The fifth Korean National Health and Nutrition Examination Survey (K-NHANES V). As a result, physically active participants were 0.54 times (OR;95% CI, p<0.001) less likely to use inpatient health care and 0.73 times (OR;95% CI, p=0.040) less likely to use outpatient health care and 0.75 times (OR;95% CI, p<0.007) less likely to use drugstores than physically inactive participants, and the frequency of health care use was lower. In addition, physically minimal active participants were 0.64 times (OR;95% CI, p<0.001) less likely to use inpatient health care than physically inactive participants; the frequency of other health care facilities was lower. In conclusion, the relationship between being physically active and lower health care utilization among Korean elderly identified in this study. This suggests that being physically active is helpful to the elderly, not only in health promotion and improving quality of life, but also in reduced medical expenditure.
