Currently many safety assessment tests are conducted by crashing a vehicle against a rigid or deformable barrier. It is quite rational to evaluate crash performance of a vehicle in a barrier test in terms of vehicle stiffness and strength. However, there has been a lot of debate on whether barrier testing is a duplicate of real world crash collisions. One of the issues is car to car compatability. There are two essential subjects in compatability. One is partner-protection when crashing into another vehicle and the other is self-protection when struck by another vehicle. When considering a car to car frontal crash between a mini car and a large heavy car, it is necessary to evaluate human body stiffness of each vehicle. In this study, in order to evaluate the compatability of cars in car-to-car crashes, four tests were conducted. Test speed of each car is 48.3km/h, and the overlap of the mini and large car is $40\%$, and the overlap of the small cars is $100\%$. In all tests, only a drive dummy is used. The test results of the car to car crash test show that vehicle safety standard of mini car is not satisfied compared with large heavy car and HIC value of mini car is higher than large car. In this case observed that the relatively lower stiffness and weight of the mini car resulted in absorbing a large share of the total input energy of the system when crashed into the large heavy car.

Background: This study purposed to compare the difference on medical utilization and health expenditure of baby boomer generation by depression between gender. Methods: Korea Welfare Panel Survey 2016, provided by the Korea Institute for Health and Social Affairs, was used for the analysis. For the research, we used the two-part model, yes or no of use (part 1), and frequency of use (part 2) for medical utilization. The dependent variables are the whether or not to use of hospitalization services, outpatient services, length of stay, outpatient service visits, and health expenditure. And the independent variables are used as the predisposing (education, spouse presence), enabling (insurance type, private insurance, economic activity, income), and need (chronic disease, self-rated health, disability) factors in the Andersen behavior model. Depression was used as intervening variables. Structural equation model and multiple group analysis by gender were used. Results: There were differences in the medical care usage and cost between men and women in baby boomer. For men, mediating effects of depression were present at the hospitalization (yes/no), length of stay, and health expenditure. On the other hand, for women, the mediating effect of depression was found only at the outpatient visits. Specially, depression was working at the medical services by the different way between gender. The size of effect (multiple group analysis) was affected by significant differences between men and women. Conclusion: This study found that the mediating effect of depression is increased medical usage and health expenditure and the effect factors are different by gender. Therefore, it is necessary to establish a medical care policy considering the socio-economic characteristics of baby boomers.

This study estimated the direct and indirect socioeconomic costs of 238 diseases and 22 injuries from a social perspective in Korea from 2007 to 2015. The socioeconomic cost of each disease group was calculated based on the Korean Standard Disease Classification System. Direct costs were estimated using health insurance claims data provided by the National Health Insurance Service. The numbers of outpatients and inpatients with the main diagnostic codes for each disease were selected as a proxy indicator for estimating patients' medical use behavior by disease. The economic burden of disease from 2007 to 2015 showed an approximately 20% increase in total costs. From 2007 to 2015, communicable diseases (including infectious, maternal, pediatric, and nutritional diseases) accounted for 8.9-12.2% of the socioeconomic burden, while non-infectious diseases accounted for 65.7-70.7% and injuries accounted for 19.1-22.8%. The top 5 diseases in terms of the socioeconomic burden were self-harm (which took the top spot for 8 years), followed by cirrhosis of the liver, liver cancer, ischemic heart disease, and upper respiratory infections in 2007. Since 2010, the economic burden of conditions such as low back pain, falls, and acute bronchitis has been included in this ranking. This study expanded the scope of calculating the burden of disease at the national level by calculating the burden of disease in Koreans by gender and disease. These findings can be used as indicators of health equality and as useful data for establishing community-centered (or customized) health promotion policies, projects, and national health policy goals.

The purpose of this study is to examine the factors associated with the probability and levels of the health service utilization among the disabled elderly in Korea. The sample includes 2,111 people older than 65 who are extracted from the 2008 National Survey on People with Disabilities. More than half (54.3%) of the sample experienced at least 1 outpatient physician visit within two weeks and 26.7% were hospitalized within a year. The key factors associated with the outpatient visits were health insurance status, the existence of chronic disease, self-rated health, the Activities of Daily Living (ADLs), as well as renal impairment. Similarly, the utilization of inpatient care was related to health insurance status along with the existence of the internal organ disabilities such as cardiac or respiratory disorders. The study implies the need for the health care policies regarding the prevention of chronic diseases, dependency for daily activities of the elderly, and a management system that specifically targets those with internal organ disabilities. Moreover, the study suggests that financial supports for the low-income group would be helpful to increase their access to health service utilization.

Purpose: This study aimed to identify the factors affecting compliance with personal protective equipment (PPE) use among medical device reprocessing staff. Methods: This descriptive cross-sectional study included 163 cleaning staff members from ten general hospitals in Seoul and Gyeonggi. Data were collected using self-report questionnaires administered between July and September 2023. Analysis included t-tests, ANOVA, Pearson's correlation coefficient, Bonferroni correction, and multiple regression, conducted using SAS ver.9.4. Results: Statistically significant differences in compliance with PPE were found based on department and exposure to contamination within six months (t=-2.82, p=.007). Attitudes toward PPE (r=.22, p=.006) and awareness of the safety climate (r=.22, p=.006) showed a statistically significant positive correlation with PPE compliance. Factors influencing use of personal protective equipment by cleaning staff during medical device reprocessing were department, compliance with PPE, and awareness of the safety climate. The explanatory power of these factors was 58.0%. Conclusion: Improving PPE compliance and creating a safe cleaning environment entails fostering a supportive safety climate. Additionally, regular training that takes into consideration the characteristics of the cleaning staff, alongside continuous monitoring, is required.

A household survey was conducted to determine the utilization rate of medical facilities and to identify the factors related with the utilization in the South District of Taegu from July 3 to July 15, 1988. Study population included 1,723 family members of 431 households which were selected by one-stage simple cluster random sampling. Well trained medical college students interviewed mainly housewives with a structurized questionnaire. Morbidity rate of acute illness during the 2-week period was 101 per 1,000 persons and it was highest in the age group of 9 years below. The rate for chronic illness was 77 per 1,000 persons, increasing with age, low income and medicaid benefit. During the 2-week period, 689 of 1,000 persons utilized the medical facilities. Of the facilities, most number, 294, used hospital and clinic, and the order ran as pharmacy, health center, and herb medical clinic. The utilization rate was higher in the female, 70-year and older group, medicaid group, the lowest income class and self-employed group than other groups. The average number of visits among users of medical facilities during the 2-week period was 3.25. those who visited medical facilities most frequently were females, the 70-year and older group, the lowest income class and blue collar worker group. During one-year period, admission rate of 1,000 persons was 27.6 and that of female was 38.9, higher than that of male. the eldest group had the highest admission rate. Admission rate of medical insurance beneficiaries was twice or higher than non-beneficiaries. The higher the family monthly income, the more frequently they admitted. During one-year period, average admission days of the persons hospitalized were 22.5 days and males were hospitalized longer than females. The groups which were hospitalized longest were those between the ages of 40 and 49, medical insurance beneficiaries, the lowest income group and unemployed group. During one-year period, average admission days of 1,000 persons were 560 days and those of female were 661 days, more than those of male. The guoups which had the longest admission days were those above 70 years of age, the lowest income and unemployed groups. The medical insurance beneficiaries were three times or longer than non-beneficiaries. In logistic regression analysis of utilization of physician significant independent variables were the 9-year and younger group(+), the 70-year and older group(+), acute illness episode(+), chronic illness episode(+), medical insurance beneficiary(+) and white collar workers(-). Acute and chronic illness episode(+), and medical insurance for government employees and private school teacher(-) were significant variables in analysis of utilization of pharmacy. In multiple regression analysis of the number of physician visits, siginificant variables were acute illnes episode(+), chronic illness episode(+), industrial, occupational and regional medical insurance beneficiary(+), white collar workers(-). Acute and chronic illness episode(+), and medical insurance beneficiary(-) were significant variables in analysis of the number of pharmacy visits. In logistic regression analysis of admission event, significant independent variables were the 9-year and younger group(+), the 70-year and older group(+) , chronic illness episode(+), and medical insurance beneficiary(+).

It is clear that the women's participation in social activity is dramatically increased in civilian field as well as military profession. Because of the characteristics of military nursing service, there are many difficulties. Frequent move, medical insurance, baby care. and the education are typical forms of difficulties for nurse officers in the military. The purpose of this research is to contribute to the perfect execution of nursing service. guarantee the active attitude for research and improve the combat strength by solving those private and economic problems. The method of research was analysis of question survey and the review of related literatures. The subject of research was 300 active nurse officers who work at the Army Hospitals. The survey was conducted 14 days from Oct 15 to Oct 28. The collected data was processed by computer using SPSS(Statistical Package of Social Science). Frequencies and percentages were used to examine the demographic characteristics of subject, and T-test was also used in the case of necessity. The result showed as follows; As the general characteristics of subject group; 28.7 years of average age, 73.6 months of service period, 63.4% of married. In regard of specialty; General 57.7%. Intensive Care 12.7% and Psychiatries 8.8%. The dissatisfactory factors about military welfare system were the difficulties in children education (36.9%). disadvantages on the civil medical insurance system (27.3%), and little chance of self education and development (21.5%). The problems in performing their duties were shown as dwelling instability due to frequent move (67.7%), and bring up children (14.2%). The reasons for resigning their job were shown as the instability of living status (64.2%), bring up children (18.8%) and dissatisfaction to the service (11.2%). The residential status was shown that military offered houses (45.2%), rental houses (29.3%) and own houses(14.64). The average numbers of moving residencies were; 3-4 time(34.6%), less than 2 times(33.1%), and 5-7 times(21.5%). Higher than 94.7% of the subject group spent more than 50.000 Won. In regard of education, they wanted to attend graduate school with their own expense(26.2%), computer science(20%) and Office Job Training(20%). The ways of taking care of children were mother-in-low(49.6%), mother(14.6%), and others(25%). The average expenditure per month for children were 20-30 hundred Won(44.2%), 10-20 hundred Won(25%) and 30-40 hundred Won(22.3%). The places of children care selected were public or occupational care center(56.2%), religious organization(20.8%), and other center managed by social organizations(10.4%). The result of survey for general welfare of nurse officers are as follows; By and large they seem to be satisfied with their job. however. there are some dissatisfactory factors. They are children care facilties, promotion. income. welfare facilities. disadvantage in medical insurance and civil hospitals. house purchase. unfair chances in specialty training. influence on promotion by educational status. and insufficient role for their children and husbands. As conclusion. the recommendations for improving nursing service are as follows; 1. Children care center managed by occupation 2. Dormitory system for children by military personnel 3. Equal opportunities in education according to ability 4. Reasonable moving price according to the distance and scope of family and extra allowance

This study aimed to explore the direction of development of agricultural safety and health system in Korea based on experience on Farmers' Occupational Health Services (FOHS) of Finland. In Finland additional and specialized Occupational Health Services (OHS) for self-employed farmers were developed and have been conducted by municipal primary health care centers with cooperation of National Centre for Agricultural Health (NCAH) of Finnish Institute of Occupational Health, Social Insurance Institute (SII) and Farmers' Social Insurance Institution (FSII). Based on the study, in order to activate the FOHS in Korea, the analysis results could suggest the development of four prerequisites. Firstly, center for farmers' safety and health like NCAH, which conducts surveillance on health and safety status, standardization of intervention contents and epidemiological research is needed in national institution. Secondly, development of evaluation tools with lower cost and difficulty like walk-through survey for checking status of systems of safety in the farms is needed. Thirdly, farmers' occupational health insurance which will be initiated on near future should be connected to preventive intervention programs like FOHS. Lastly, training and qualification of more local occupational health experts and units is needed.

In recent years, national health insurance(NHI) coverage had been expanded gradually for cancer as a severe disease requiring high level of medical expenditure, to reduce patient's financial burden. But, subjective burdens level for out-of-pocket(OOP) money expense are still considerable owing to high medical cost and decent numbers of services not covered by benefit plan. This study aimed to investigate OOP medical expenditures and identify factors influencing subjective financial burden in cancer patients. A 28-items questionnaire for self-reporting by responders was designed to satisfy study goal and finalized following by one pilot study and experts' verification process. Subjects were enrolled during July to October 2010 through regular meetings organized by five patient or patient-advocacy groups had acknowledged the study purpose. Subjects who aged 20 or more, have histories of cancer diagnosis and anticancer drug use, and voluntarily agreed to participate in this study were recruited. Total 107 subjects included in the analysis have cancer lesions in breast, colon, kidney, liver or stomach at the stages from I to IV. Approximately 73% of them has passed less than 5 years since cancer diagnosis. For the OOP medical expenditure regarding cancer, less 6 million won was in 31%, 6-15 million won in 35% and more than 15 million won in 28% of responders, and more than half responders(58%) felt financial burden subjectively. 63% of responders had subscribed commercial insurances, resulting in money receipts of more than 10 million won since cancer diagnoses in 76% of responders. Logistic regression results showed significant differences in subjective OOP financial burden level depending on gender, household income level, benefit type, commercial insurance money receipt degree, year cancer diagnosed, cancer lesion, therapy type, duration of anticancer drug use, drug listing in national formulary, total OOP medical expenditure and total OOP anticancer drug expense. They had mixed feelings both wishes to expand NHI coverage to reduce financial burden(70%) and no willingness to increase premium(59%). This result suggested that NHI might direct future strategies to reduce absolute total OOP medical cost and expand benefit plan coverage in higher burden groups in particular.

The purposesof the study are to analyze the community nursing center in U.S.A and to develop the model of nursing care system based on nurse-midwifery clinic in community for women's health in Korea. 1. In America nursing center is defined as nurse-anchored system of primary care delivery or neighborhood health center. Nursing centers are identified the following four types: (1) community outreach centers, which are similar to traditional public health clinics: (2) institutional-based centers following the mission of a large institution, such as a hospital or university: (3) wellness/health promotion centers, which offer screening, education, counseling, triage, and health maintenance services: and (4) independent practice. Nursing centers are a concept of services provided by nurses in practice arrangements in a community. Nursing centers offer a variety of services, ranging from primary care provided by advanced practice nurses with medical acute management and nursing care to the more traditional education, health promotion, screening wellness and coordination services. Some services, such as the care provided by advanced practice nurses are reimbursed under various insurance plan in some instances and states, where as others, such as preventive and educational services, are not. Thus, lack of reimbursement has threatened the survival of some centers. Licensing of nursing centers varies by state and program and accreditation of nursing centers is also limited. 52% of centers are affiliated with another facility and 48% are freestanding centers. The number of registered nurse at the nursing centers ranges from just one to 115, with a mean of eight RNs peragency and a median of three. Nursing centers avail ability varies: 14% are open 24 hours, 27% have variable short hours, 23% are open 6-7 days per week, and 36% are open Monday- Friday. As the result of my visiting three health centers in Seattle and San Francisco, the women's primary care nurse practitioners focus on a systematic and comprehensive assessment of the health status of women and diagnosis and management of common physical and psychosocial health concerns of women in ambulatory settings. Therapeutic nursing strategies are directed toward self-care, risk reoduction, health surveillance, stress reduction, healthy nutrition, social support, healthy coping, psychological well-being, and pharmacological therapy. They function as primary care providers for the well ness and illness care of women from adolescence through the older adult years and pregnant families. 2. In Korea a nurse-midwife practices independently for pregnant women's health including childbearing family at her own clinic in community. Her services are reimbursed under national health insurance but they are not paid on a fee-for-service schedule covering items. Analyzing the nursing centers in America, I suggest that nurse-midwifery clinics offer primary care for women and home care for chronic ill patients. The health law and health insurance policy should be reovised in order to expand nurse-midwife's and home care nurse's roles at nurse-midwifery clinic.
