Purpose: The purpose of this study was to provide basic data for improving the response capacity of 119 EMS systems by analyzing the effects of particulate matter on cardio-cerebrovascular and respiratory symptoms in the pre-hospital stage. Methods: We examined 46,389 patients who transferred to the hospital with complaints of cardiopulmonary arrest and cardio-cerebrovascular and respiratory symptoms by 119 ambulances in Incheon from 2016 to 2018. Results: The probability of 119 emergency dispatch for patients with cardiopulmonary arrest increased 2.8-4.0% from the day of symptom onset until two days before hospital presentation as particulate matter 10㎛ or less in diameter(PM₁₀) increased by 10㎍/㎥ (OR=1.028; 95% CI=1.014-1.041, p=0.000, lag 0), (OR=1.040; 95% CI=1.024-1.056, p=0.000, lag 1), (OR=1.032; 95% CI=1.016-1.049, p=0.000, lag 2). Meanwhile, emergency dispatch increased 3.6-6.1% for PM_2.5 in creased by 10㎍/㎥ (OR=1.046; 95% CI=1.024-1.068, p=0.000, lag 0), (OR=1.061; 95% CI=1.035-1.088, p=.000, lag 1), and (OR=1.036; 95% CI=1.010-1.063, p=0.006, lag 2). Conclusion: Emergency medical technicians (EMTs) who respond to 119 calls should rapidly and accurately evaluate patients and provide professional emergency care by identifying the characteristics of the vulnerable groups relative to particulate matter size. To prevent the occurrence and exacerbation of symptoms caused by particulate matter, EMTs should be prepared and equipped with a response system for high particulate matter in the EMS system.

The study examined work and family life of married women employed in a manufacturing industry. Data were gathered from the use of face-to-face interview method from a sample of 230 married working women. The major findings of this study can be summarized as follows: (1) Most of the respondents found the work repetitive and unappealing, with the double burden of a paid work and housework. Thus, it is necessary for the government to implement social policies for married working women, such as establishment of various child care centers, part-time jobs, and dissemination of egalitarian sex-role attitudes. (2) More than half of the respondents were born in rural areas and immigrated to the urban sectors, forming a nuclear family structure. Most of these women were married with love, but some of them could not have a marriage ceremony because of the economic reasons. Thus, it may be necessary to increase the service centers to offer a free marital ceremony. (3) About 30% of the respondents answered they left their preschool aged children unattended, after dismissing from a kindergarden on a private institution. It was shown that working women, even though they were in charge of child-rearing, did not have an effective mechanism to control or protect their children while they were away from home. Most of them frequently used material compensations from their children in order to make up their absence at home. (4) It was found that the strategy for working women to decrease a dual-role conflict is to make a hierachy on the work they to do and to do only basic housework for everyday life and to do the rest of work on a off-day.

오늘날의 모든 통신은 IP(Internet Protocol)을 기반으로 통합 및 연계되어 발전하고 있으며, IP를 통하여 사용자에게 '언제, 어디서나, 끊김 없는 서비스'를 제공할 수 있게 하기 위하여 많은 연구들이 이루어지고 있다. IETF에서는 IPv6를 사용하여 이동성을 제공하는 MIPv6를 제안하였으나 이동노드가 네트워크를 이동할 때 마다 HA(Home Agent)와 CN(Correspondent Node)에게 BU(Binding Update) 메시지를 보냄으로써 많은 Overhead와 전송지연이 발생한다. 이에 현재 MAP(Mobility Anchor Pointer)를 사용하여 CN에게 아무런 영향을 끼치지 않으면서 이동노드가 매번 핸드오버마다 발생하는 HA와 CN에게의 BU를 통한 지연과 Overhead를 줄일 수 있는 HMIPv6를 개발하였다. HMIPv6는 이동노드가 MAP 내부에서 핸드오버시, 같은 RCoA(Regional Care of Address)를 가지고 있음으로 BU를 HA와 CN에게 전달하지 않고 MAP가 직접 처리하여 MAP 내부에서의 이동에 관하여 전송지연과 Overhead 문제를 해결하였지만, MAP와 MAP간의 Macro 핸드오버를 효율적으로 수행하지 못한다. 본 논문은 HMIPv6환경에서 MAP간의 Macro 핸드오버시, 이동노드의 위치정보를 이용한 핸드오버를 사용함으로써 효율을 높일 수 있는 방안을 제시한다.

Purpose: This study was conducted in order to explore self-perceived objectives, effects, determinant factors of satisfaction and demands on home-based rehabilitation service (HBRS) based on a community-based rehabilitation (CBR) model in community-dwelling disabilities. Methods: This research was conducted through in-depth interview. HBRS was conducted by four physical therapists for one hour a day, once a week, for eight weeks. After an eight-week intervention period, in-depth interviews were conducted using a semi-structured questionnaire for five recipients of HBRS and six care givers. Results: For the physical effect, some participants experienced positive effects, whereas others did not due to the short-term intervention period. For the social and emotional effects, 'occurrence of motivation for exercise', 'change of surroundings' and 'sorriness for the therapist' emerged as keywords. For the determinant factors of satisfaction, 'movement-inducing therapy', 'therapy from the specialist', 'development of friendship & social network', and 'learning the way of self-rehabilitation' emerged as keywords. For further demands on HBRS, participants stated that 'sufficient time for therapy', 'user opinion-reflected therapy', 'additional instructions for therapeutic exercise & activities of daily living', and 'active promotion for HBRS' were necessary. Conclusion: Participants were satisfied with the physical, social, emotional, and educational aspects of HBRS. In particular, the participants regarded educational aspects as the significant factor throughout self-perceived objectives, determinant factors of satisfaction and the demands. This result suggests that when providing HBRS to community-dwelling persons with disabilities, therapists should recognize the necessity and significance not only of the physical, but also the educational aspect of HBRS.

Because of the rising healthcare costs, there is a growing need for developing efficiency indicators for medical resources use and measuring efficiency of healthcare providers and healthcare systems using them. In this study, we aimed to develop efficiency indicators for medical resources use by means of Delphi technique. We systematically reviewed the existing measures of medical resource use. Thirty nine indicators were selected as a candidates across the six domains: medical personnel, medical equipment, medical facilities, ethical management, resource efficiency, and drug use. To develop efficiency indicators with professional consensus, a 2-round Delphi survey was conducted among 29 professional experts. The following indicators were selected based on the Delphi survey results: adjusted number of the patient per day and level of the nurse number medical personnel in medical personnel domain; the number of the scan a professional physician and the quality of the scan in medical equipment domain; bed utilization rate in medical facility domain; drug price reported pharmaceutical price by medical institutions, medical fee billing transparency, and medical care appropriateness in ethical management domain; costliness index in resource efficiency domain; and utilization of high cost drug and items per prescription in drug use domain. The efficiency indicators could provide valid information about efficiency of healthcare providers and healthcare systems with respect to their resources use and facilitate policies to improve their efficiency.

In recent years there has been a rapid influx of high cost MRI equipment into Korea. This diffusion has raised concerns about the changes it will bring for the health care utilization. Therefore, the purpose of this study is to identify socio-economic characteristics of MRI uses in Korea. A structured questionnaire was designed for this purpose, and 1, 091 users were surveyed at the 35 MRI units of 33 hospitals during a week, sometimes March 1992. The study reveals that high cost technology such as MRI, CT scanner is so prevalent in Korea. This is particularly the case in metropolitan areas. Among others, Seoul has the highest percentage of MRI equipment, 51.05%, Pusan 12.10% and Kwangju 11.9%. Unfortunately, most high cost technology equipments are foreign products. Thus, hospitals with such a high cost technology have difficulties in maintenance of the equipment. The average performance of MRI equipment has declined from 10.2 cases per day in 1988 to 7.16 cases in March 1992. Due to the rapid increase, the performance of MRI equipment seems to be deterioration. Male usere are dominant in the case of MRI use. The utilization rate has positively increased with the rise of educational level of users. The same is true for the level of income; the MRI utilization rate by income level shows that it is negatively proportional to income, which indicates that the poor have difficulties in the use of high cost technology. Particularly, the cost of MRI is so high that ordinary patients are unable to pay for it. For example, 86.3% of respondents have answered that the cost is too high even though they are insured by health insurance. This is the first empirical study on the use status of MRI. The information obtained in this study is sufficient to maintain that the Korean health insurance programme is urgently in need of improving the insurance benefit schemes. The easiest way to do this is to include provision of high cost technology service into the benefit package.

Purpose: Trauma incidence and hospitalizations of trauma patients are generally believed to be affected by season and weather. The objective of this study was to explore possible associations of the hospitalization rate of trauma patients with weather and time variables at a single regional trauma center in South Korea. Methods: Trauma hospitalization data were obtained from a regional trauma center in South Korea from January 1, 2017 to December 31, 2019. In total, from 6,788 patients with trauma, data of 3,667 patients were analyzed, excluding those from outside the city where the trauma center was located. Hourly weather service data were obtained from the Korea Meteorological Administration. Results: The hospitalization rate showed positive correlations with temperature (r=0.635) and wind speed (r=0.501), but a negative correlation with humidity (r=-0.620). It showed no significant correlation (r=0.036) with precipitation. The hospitalization rate also showed significant correlations with time of day (p=0.033) and month (p=0.22). Conclusions: Weather and time affected the number of hospitalizations at a trauma center. The findings of this study could be used to determine care delivery, staffing, and resource allocation plans at trauma centers and emergency departments.

Purpose: This study attempted to recommend a revision of inpatient nursing fees based on analyzing current and appropriate staffing levels. Methods: Staffing grades and their inpatient nursing fees as of the first quarter of 2022 were analyzed. Nurse managers and staff nurses answered surveys about the current and appropriate staffing levels, working days, and monthly salary. A total of 101 nurse managers and 588 staff nurses working in general wards at tertiary hospitals and general hospitals participated in the study. Results: The results showed that grade 1 staffing was found in 73.3% of tertiary hospitals and 63.7% of general hospitals. The current staffing ratios of tertiary hospitals and general hospitals were 1:9.3 and 1:10.4, respectively. The appropriate staffing ratios according to nurse managers and staff nurses at tertiary hospitals were 1:7.6 and 1:7.0, respectively, and 1:8.7 and 1:8.8 in general hospitals, respectively. The average estimated annual working days of staff nurses were 235.2 days in tertiary hospitals and 240.0 days in general hospitals. The median monthly salary for staff nurses was 4.957 million won in tertiary hospitals and 4.140 million won in general hospitals. The new staffing grade system was suggested from 1:6 (Grade 1) to 1:12 (Grade 5). The new inpatient nursing fee schedules were recommended to be paid based on nursing hours per patient day of each grade. Conclusion: The new staffing grade and inpatient nursing fee schedules are expected to increase staffing levels, improve the quality of nursing care, and provide a better work environment for nurses.
