Health policy is directed to equity in the provision of primary care for rural people before the year of 2, 000. This study aimed to define and identify the need for physician's care by using empirical data, and suggested an alternative of the primary care delivery system in rural areas to the government. 1. Twenty percent of the study population wanted to obtain any form of medical care services. : 9.3 percent of the population was in need for physician's care; 15 percent of the need was met by physicians, while 85 percent remained unmet at the time of survey in 1979. 2. For meeting all the need for physician's primary care, 2.9 annual physician visits per capita are demanded. An alternative, which was devised in some favourable way at reasonable cost in rural settings, was suggested. It was to deploy the physician extender such as community health practitioner in the infrastructure of the health care delivery system, whose supervision is provided by physician, based on experience of the KHDI health demonstration project. 3. One physician, two community health practitioners and two community health aides should be assigned in distant locations for meeting all the estimated need for physician's primary care for 10, 000 rural underserved residents.

In this paper, we present the Tele-consulting system of radiology, which uses the communication network as asymetric satellite data communication system. The asymetric satellite data communication system uses receive-only satellite links or data delivery and PSTN(Public Switched Telephone Network) modem or N-ISDN(Integrate Services Digital Network) for communication. The satellite communication linking shows the very high-speed performance than 28.8kbps modem linking. The satellite linking is 5 - 10 times aster than the modem linking. Consequently, we get the conclusion that our system is suitable or tele-radiology and telemedicine.

It is generally said that primary health care is the base of health delivery system. But in Korea, the primary care have not performed its roles well. To resolve these problems, the government has elaborate some policy measures. One of them is 'Attending Hospital System'. The purposes of this study are to understand Attending Hospital System and to anticipate the change of general hospital and clinic by this regulation.

Purpose: A cost analysis for nursing services in operative nursing unit, emergency nursing unit, and ambulatory nursing unit was performed using patient classification system by nursing intensity in order to determine an appropriate nursing fee schedule. Method: The data were collected from 4 secondary hospitals and 5 tertiary hospitals from November 14th 2000 to January 15th 2001. The study was conducted through four phases as follows: 1) Nursing hours of each nursing service in special nursing units were measured using three kinds of patient classification systems by nursing intensity. 2) The nursing cost of nursing services in operative nursing unit, emergency nursing unit, and ambulatory nursing units was estimated based on patient classification system by nursing intensity. Results: As a result, nursing hours by nursing intensity of each special nursing unit were measured, and every nursing cost by nursing intensity in operation room and emergency room was estimated, meanwhile, the cost of nursing services in ambulatory care units was estimated only per visit as shown in chapter 4. Conclusion: Future research on nursing cost should be extended to other special nursing units such as various intensive nursing care units, delivery room, and so on. In addition, the patient classification system should be refined for its appropriateness to apply all levels of medical institutions.

Motion of lung tumors from respiration has been reported in the literature to be as large as of 1-2 cm. This motion requires an additional margin between the Clinical Target Volume (CTV) and the Planning Target Volume (PTV). While such a margin is necessary, it may not be sufficient to ensure proper delivery of Intensity Modulated Radiotherapy (IMRT) to the CTV during the simultaneous movement of the DMLC. Gated treatment has been proposed to improve normal tissues sparing as well as to ensure accurate dose coverage of the tumor volume. The following questions have not been addressed in the literature: a) what is the dose error to a target volume without gated IMRT treatment\ulcorner b) what is an acceptable gating window for such treatment. In this study, we address these questions by proposing a novel technique for calculating the 3D dose error that would result if a lung IMRT plan were delivered without gating. The method is also generalized for gated treatment with an arbitrary triggering window. IMRT plans for three patients with lung tumor were studied. The treatment plans were generated with HELIOS for delivery with 6 MV on a CL2100 Varian linear accelerator with a 26 pair MLC. A CTV to PTV margin of 1 cm was used. An IMRT planning system searches for an optimized fluence map ${\Phi}$ (x,y) for each port, which is then converted into a dynamic MLC file (DMLC). The DMLC file contains information about MLC subfield shapes and the fractional Monitor Units (MUs) to be delivered for each subfield. With a lung tumor, a CTV that executes a quasi periodic motion z(t) does not receive ${\Phi}$ (x,y), but rather an Effective Incident Fluence EIF(x,y). We numerically evaluate the EIF(x,y) from a given DMLC file by a coordinate transformation to the Target's Eye View (TEV). In the TEV coordinate system, the CTV itself is stationary, and the MLC is seen to execute a motion -z(t) that is superimposed on the DMLC motion. The resulting EIF(x,y)is inputted back into the dose calculation engine to estimate the 3D dose to a moving CTV. In this study, we model respiratory motion as a sinusoidal function with an amplitude of 10 mm in the superior-inferior direction, a period of 5 seconds, and an initial phase of zero.

Recently, the interest in the extension of human life and personal health has been increased. Accordingly, many researchers in a pharmacy and a medical world have been making efforts to improve the sustained drug release property and the stability of drug release property in a body. Many biological researches have demonstrated that chitosan derivatives are effective, safe absorption enhancers that can improve the delivery efficiency of drug and vaccine, and they are suitable for controlled drug release because they have good stability, bio-compatibility, and biodegradability. In this study the experiment was performed in vivo by utilizing chitosan nanoparticles as a biopolymer to control drug delivery rate at an optimal temperature, pH, and concentration. It was observed that nanoparticles containing insulin could effectively control the blood glucose at a low level.

Treatment of polymicrobial infected musculoskeletal defects continues to be a challenge in orthopaedics. This research investigated single and dual-delivery of two antibiotics, vancomycin and amikacin, targeting different classes of microorganism from a biodegradable calcium sulfate-chitosan-nHA microsphere composite scaffold. The addition of chitosan-nHA was included to provide additional structure for cellular attachment and as a secondary drug-loading device. All scaffolds exhibited an initial burst of antibiotics, but groups containing chitosan reduced the burst for amikacin at 1hr by 50%, and vancomycin by 14-25% over the first 2 days. Extended elution was present in groups containing chitosan; amikacin was above MIC ($2-4{\mu}g/mL$, Pseudomonas aeruginosa) for 7-42 days and vancomycin was above MIC ($0.5-1{\mu}g/mL$ Staphylococcus aureus) for 42 days. The antibiotic activity of the eluates was tested against S. aureus and P. aeruginosa. The elution from the dual-loaded scaffold was most effective against S. aureus (bacteriostatic 34 days and bactericidal 27 days), compared to vancomycin-loaded scaffolds (bacteriostatic and bactericidal 14 days). The dual- and amikacin-loaded scaffolds were effective against P. aeruginosa, but eluates exhibited very short antibacterial properties; only 24 hours bacteriostatic and 1-5 hours bactericidal activity. For all groups, vancomycin recovery was near 100% whereas the amikacin recovery was 41%. In conclusion, in the presence of chitosan-nHA microspheres, the dual-antibiotic loaded scaffold was able to sustain an extended vancomycin elution longer than individually loaded scaffolds. The composite scaffold shows promise as a dual-drug delivery system for infected orthopaedic wounds and overcomes some deficits of other dual-delivery systems by extending the antibiotic release.

In contrast to the increase in demand for high quality healthcare, there is limited medical human resources such as doctors and nurses so an excessive amount of workload is being forced to them. Therefore, a patient monitoring system using USN(Ubiquitous Sensor Network) is becoming a solution. This paper proposes a patient monitoring system applying USN in maternity hospital to reduce the workload of nurses. According to the efficiency evaluation test based on the model of two university hospitals(S, K University Hospital) and their doctor's diagnosis, the results showed that under the circumstances that one nurse is in charge of 12 patients(6 normal delivery patients and 6 cesarean delivery patients), a total of 1,260 minutes of workload was saved during hospitalization period(5 days). Also, we compared the workload of nurses with or without our proposed system, and the figures showed that in case of normal delivery patients, the workload of nurses decreased by 50 minutes per patient, whereas in case of cesarean delivery patients, the workload of nurses decreased by 130 minutes per patient.

This study examined the trend of healthcare status and compared the status of South Korea and other member of the Organization for Economic Cooperation and Development (OECD) using the OECD health statistics 2022. We used the OECD health statistics from 2022 and a position value for relative comparison (PARC) index to compare the five elements of the healthcare system. The study also used a Mann-Kendall test to analyze the trend of the PARC values from 2000 to the present year. The findings of the study indicate that many South Korea's PARC values were higher than the OECD median. But practicing physician in supply part and medical cost were lower than OECD median but the trend significantly increased. Medical accessibility part and quality of care part except primary care, and mental health had a high relative position but the trend did not increased significantly. After outbreak of coronavirus disease 2019, there were changes in medical accessibility. Health screening and vaccinations showed an overall decline in 2020 compared to 2019. These results suggest that policymakers need to take necessary steps for a sustainable healthcare system in the country.
