Purpose: In relation to perinatal healthcare, medical institutions and resources are limitative and also are in a state of flux due to the therapeutic specialty. We analyzed requests for interhospital transfers received by Busan 1339 Emergency Medical Information Center (EMIC) to grasp the state of perinatal healthcare delivery system. Methods: This study was conducted on the basis of data inputted into the computing system of Busan 1339 EMIC, between January 1 and December 31, 2009. In connection with 378 pregnant women and 136 newborns who were required to transfer, retrospective analyses were made of the success rate of transfer (SR), the number of contacted hospitals, the time required for transfer and the reason of transfer and refusal. Results: In the case of pregnant women, the SR were 65.5%. They came in contact with 2.7 hospitals, and it took 24.4 minutes. As for the reason of transfer, preterm labor accounted for the highest proportion. In the case of newborns, the SR were 71.3%. They came in contact with 2.4 hospitals, and it took 15.6 minutes. The most common reason of transfer were respiratory symptoms. In the reason of refusal with pregnant women and newborn, the lack of medical staff, medical equipments and wards accounted for great. Conclusion: Many pregnant women and newborns have been transferred to hospitals by EMIC, but the SR has not been higher yet. Accordingly, there is a need to evaluate the propriety of perinatal treatment system, as well as to set up effective perinatal healthcare delivery system.

Purpose: In general, We discharged radioactive wastewater and sewages less than $8.1{\times}10^{-13}$ Ci/ml in a exclusive water-purifier tank. Our hospital operating three exclusive water-purifier tank for radioactive wastewater and sewages of 60 tons capacity respectively. In order to meet the criteria it need a enough decay more than 125 days per each exclusive tank. However, recently we fell into the serious situation that decay period was decreased remarkably, owing to the wastewater amount increased rapidly by enlarge the therapy ward. For that reason, in this article, I'd like to say the way that reducing of radioactive wastewater and sewages rationally. Materials and Methods: From January, 2006 to October, four hundred and two cases were analyzed. They were all hospitalized during 3 days and 2 nights. We calculated the average amount of water used (include toilet water used, shower water used, washstand water used, $\cdots$), each exclusive water-purifier tank's decay period, as well as try to search the increased factors about water-purifier tank inflow flux by re-analysis of the procedure of radioisotope therapy step by step. Results: We could increase each exclusive water-purifier tank's decay period from 84 days to 130 days through the improvement about following cause: (1) Improvement of conventional toilet stool for excessive water waste $\rightarrow$ Replacement of water saving style toilet stool (2) Prevention of unnecessary shower and wash (3) Stop the diuretics taking during hospitalization (4) Analysis of relationship between water intakes and residual dose of body (5) Education about outside toilet utilization before the administration (6) Changed each water-purifier tank's maximum level from85% to 90% Conclusion: The originality of our efforts are not only software but hardware performance improvements. Incidentally the side of software's are change of therapy procedures and protocols, the side of hardware's are replacement of water saving style toilet stool and change of each water-purifier tank's maximum level. Thus even if a long lapse of time, problem such as return to the former conditions may not happen. Besides, We expect that our trials become a new reasonable model in similar situation.

This study was conducted to analyze factors affecting the length of stay in children with injuries by determining relationships between length of stay and characteristics of children(aged 0 to 12) with injuries. 7,804 patients aged 0 to 12 who participated in the Korea Nation Hospital Discharge In-Depth Injury Surveys, got a diagnosis of sequelae of injuries and of other consequences of external causes(S00-T98), and were discharged between 1 January 2016 and 31 December 2020 were investigated. A frequency analysis, independent samples t-test, and ANOVA were performed. Also, to identify factors affecting the length of stay, a regression analysis was performed. The average length of stay for the patients investigated in this study was 5.5 days. The length of stay for school-age children(aged 7 to 12) and children who had either public or private coverage was higher than that for preschoolers(aged 0 to 6) and children who didn't have public or private coverage, respectively. The length of stay for children admitted to a hospital in a rural area(Jeolla-do or Gyeongsang-do) was higher than that for children admitted to a hospital in a metropolitan area and the length of stay for children admitted to a hospital that had 100-299 hospital beds was relatively long. However, children who first visited a hospital for outpatient care stayed relatively short in hospital and children who had been burned or injured in traffic crashes stayed relatively long in hospital. Children who got a secondary diagnosis and had a principal procedure or who died after being discharged were in hospital for a long time. The findings of this study shall be useful, as they identified characteristics related to the length of stay for Korean children with injuries and factors that determine the length of stay for those children by analyzing the national dataset, or more specifically, the data from the Korea National Hospital Discharge In-Depth Injury Surveys. The risk of child injuries can be easily reduced by taking actions to prevent them and providing safety education programs. The present study has provided essential baseline data for the provision of aggressive care for child injuries and the establishment of a range of policies for child injury prevention.

This research examined use rate and profitability of equipment in hospital scale with about 500 beds to present data including to review before introducing PACS with the checklist included in preparation and proposal based on expected profit suggested by operation department and cost and use rate of the expensive medical equipment were analyzed. It was proved that profit was generated in the research subject hospital if PACS is introduced. Three to five year of lease is proper for the purchase method of medical equipment. Profit after two year of use will surpass investment cost and generate clear profit. Based on the profit generated from operation of radiology department, the purchase amount to introduce PACS at the hospital will be retrieved after about 1.9 years for the investment. The number of reshoot test at radiology department will be decreased and film, development, and fixer will not be necessary to buy so the operation cost will be reduced. Moreover, other than actual profit increased, the hospital can improve its reputation and employees can reduce their works and get better working environment with less stress. Their job satisfaction will be increased so they can improve service quality and it is good for marketing strategy of the hospital. As a result of this research, it was proved that the small and general hospital should have expected profit with introduction of PACS and analyze its contribution to treatment service and profit after the purchase. Then, the hospital should make a proposal for introduction of the medical equipment and establish effective operation plan.

This study is analyzed the implementation of medical aid for patients over 65 years of age who are among the discharged from hospitals with the capacity of over 100 beds. I have analyzed it with the data from an in-depth study of injury surveillance of discharged patients from hospitals done in a national project in 2004. After analyzing the results of the data from the beginning of this national project to the data collected in 2008, I could get the results that the rate of discharged patients over 65 years of age increased every year. Among them, the rate of discharged women was higher than that of the men, and the rate of deaths while at the hospital for patients over 65 years of age was higher than that of patients less than 65 years of age. The rate of operations done on patients over 65 was lower than that of patients under 65 years of age. The results of a diagnosis of popular symptoms showed that the rate of the diagnosis of cerebral infraction and structure of the heart at the circulatory organ was higher. In addition, the rate of the diagnosis of lung cancer, pneumonia, and chronic obstructive lung disease was higher, as well as the rates of gastric cancer, diabetes, liver cancer, and colorectal cancer. The results showed that the operation of the nerve system or cardiovascular system were higher. Therefore, according to this result, we should prioritize and allocate resources to the elderly people when setting up a management policy. And also, we should promote healthcare for elderly people after considering the characteristics of the implementation of medical aid in preparation of a super-aged society.

The purpose of this study is to provide preliminary data for political measures to minimize the variations by understanding the regional variations and trends of hospital services for heart diseases, and analyzing the factors that could occur any variations. The various data collected from nation-wide inpatient services conducted separately by small region show that there have been some differences in income level, supply of medical resources, standardized rate of hospitalization by sex and age, health level in the residence, and the length of stay per head. Then it indicated that the number of special medical equipment per 10,000 people and the rate of vigorous physical activity have the highest influence over the regional variations in using hospital services. On the other hand, the number of sick-beds per 10,000 people, the number of special medical equipment, and the present smoking rate have significant degree of influence on the length of stay per head. Thus, it is imperative for the authorities to set aside health promoting policies and to distribute the medical resources equitably throughout the country and to enhance the accessibility of local residents to the health care services.

This study is to recognize the relationship between better life index, nursing performance and intents to leave among hospital nurses by comparison. From July 1to July 20, 2012. we collected survey results subjecting on total 700 nurses by random sampling of hospital-class medical institutes over 200 beds located on Busan & Gyeongnam, and analyzed final 677 copies. We recognized the degrees and the differences of happiness index, professionalism, intents to leave among hospital nerses and analyzed the factors impacting on intents to leave among hospital nerses through correlation analysis and multiple regression analysis between variables. The main result is as follows: First, the average of the item related to happiness index of nurse was 3.03 (5 points of scale) and the average score of professionalism was 3.09 (medium degree) but the average score of turnover intention was 3.35 (relatively high); Second, professionalism and turnover intention according to characteristics of subjects were significant statistically (p<0.05) and turnover intention indicated a significant negative relation with happiness index and professionalism; Third, a factor which mostly impact on turnover intention indicated a significant level (p<0.05) in professionalism, happiness index, general hospital, 2.01 to 2.5 million of average pay. Based on such results, as happiness index and professionalism are indicated as major factors to turnover intention, multi-dimensional viewpoint of follow-up study including further variables is required and the plan to apply nursing intervention program for reducing turnover intention is also required.

The purpose of this study was to develop the risk-adjusted mortality model using Korean Hospital Discharge Injury data and US National Hospital Discharge Survey data and to suggest some ways to manage hospital mortality rates through comparison of Korea and United States Hospital Standardized Mortality Ratios(HSMR). This study used data mining techniques, decision tree and logistic regression, for developing Korea and United States risk-adjustment model of in-hospital mortality. By comparing Hospital Standardized Mortality Ratio(HSMR) with standardized variables, analysis shows the concrete differences between the two countries. While Korean Hospital Standardized Mortality Ratio(HSMR) is increasing every year(101.0 in 2006, 101.3 in 2007, 103.3 in 2008), HSMR appeared to be reduced in the United States(102.3 in 2006, 100.7 in 2007, 95.9 in 2008). Korean Hospital Standardized Mortality Ratios(HSMR) by hospital beds were higher than that of the United States. A two-aspect approach to management of hospital mortality rates is suggested; national and hospital levels. The government is to release Hospital Standardized Mortality Ratio(HSMR) of large hospitals and to offer consulting on effective hospital mortality management to small and medium hospitals.
