In order to implement SGR in Korea, it is necessary to analyse the factors affecting the increase of Korea Medical Insurance Cost. GDP and MEI may substitute the diverse factors affecting the Medical Cost Uprise. In this article, the GDP and MEI influence on the rates of fee schedule is measured when we implement SGR System in Korea. The various cases are made to analyse the rates of fee change. In Korea, if we implement the SGR system successfully. we should make a considerate formula using GDP and MEI because the rate of change in GDP and MEI is much more bigger than that of U.S.

Background: Price control alone may not successfully restrain growth in health expenditures. This study aimed to propose fee adjustment model suitable for Korea reflecting health service volume and to clarify applicability of the model by comparing actual conversion factor with estimated conversion factor from simulation of this model. Methods: Fee adjustment model was developed based on Alberta's fee adjustment formula in Canada and 7 alternatives were assessed according to diversely applied parameters of the model. Results: Estimated conversion factors of the tertiary care hospital and the hospital were lower than actual conversion factors, since the utilization of heath service has been increased. However, there was no big difference between estimated conversion factors and actual conversion factors of the general hospital and the clinic. Eventually this fee adjustment model could estimate proper conversion factor reflecting health service volume. Conclusion: This model may be applicable to the mechanism as determining conversion factor between insurer and provider via negotiation and controling growth in health expenditures.

수자원의 효율적인 관리를 위해서는 홍수량 자료뿐만 아니라 저 평수량의 자료도 매우 중요하며, 이는 최근의 가뭄 발생으로 인하여 용수공급 및 하천수질관리 문제에서 저수위 유량자료의 파악이 중요한 관심 대상이기 때문이다. 이를 위해서는 저수위에 대해 유량측정을 실시하여 유량자료를 확보해야 하며, 이와 더불어 연속적인 유량자료를 얻기 위해서는 신뢰성 있는 수위-유량관계곡선식이 필수적이다. 일반적으로 자연하천에서 수위-유량관계는 수위의 상승 및 하강에 따라 유량변화가 일정한 경향성을 가지고 변동을 하기 때문에 단일함수 관계로 설명이 가능하다. 하지만 갑문 조작에 영향을 받는 구간에서는 수위와 유량만의 단일함수 관계가 아닌 갑문의 개 폐에 따라 수위와 유량이 변동하는 특성을 가지고 있어 일반하천에 비해 수위-유량관계를 규명하는 것이 매우 어려운 문제이다. 본 연구는 금강 하구둑의 갑문조작에 의하여 배수영향을 받는 규암 수위관측소에 대하여 수위-하강고-유량관계를 이용한 유량환산방법, 수면경사를 매개변수로 추가한 다중 회귀식 개발, 자동유량측정 장치를 이용한 유속지수법, 기존 수위-유량관계곡선식을 이용한 유량환산, ADCP(Acoustic Doppler Current Profiler)를 이용한 유량측정성과에 대하여 비교 분석을 통하여 갑문조작에 의한 배수영향을 받는 지점의 안정적인 유량자료를 제공하는데 목적이 있다. 이와 같이 각 유량환산 방법에 따라 실측 유량과 환산유량 비교의 결과 수위-하강고 유량관계의 경우 평균 26.60%, 기존 수위-유량관계곡선의 경우 130.29%, 유속지수법의 경우 36.48%, 다중회귀식의 경우 24.65%의 상대오차가 발생하였다.

This paper is the analysis of the relationship between RQD and decay constant, blasting vi bration constant of cube root scaling and square root scaling, through experimental blast ins test in subway construction for excavation of shaft hole by bottom blasting. The magnitude of particle velocity is largely effected by the distance from blasting source, the maximum charge per delay and the properties of ground. In order to verify the effects of ground properties on blast-induced vibration, the relation-ship between magnitude of blasting vibration and Rock Quality Disignation which stands for joint property was studied. The results of test are verified that blasting vibration constant "K" and the absolute value("n") of decay constant relatively increse as RQD increased. According to the result, it can be predict the particle velocity by the blast -induced vibration in bottom blasting pattern.om blasting pattern.

본 연구에서는 경제성에 기반한 초고층건물 구조시스템의 대안평가 방안에 대하여 연구하였다. 초고층건물 구조시스템의 대안평가 항목은 크게 구조성능, 경제성, 공기의 세 가지로 나눌 수 있다. 일반적으로 구조성능은 주어진 기준의 만족여부로 평가하며, 최종적으로는 경제성이 평가에 결정적인 영향을 미치게 된다. 본 연구에서는 구조성능을 만족하는 대안에 대하여 공기를 비용으로 환산하고, 최종적으로는 물량에 의한 비용과 공기에서 환산된 비용을 합산하여 대안을 평가하는 방안을 제안하였다. 공기의 비용화는 공기의 비용연동지수를 구하고 이로부터 공기의 대체경제성비용을 산정하는 방법으로 고려하였다. 제안된 대안평가 과정은 수많은 대안을 짧은 시간에 평가할 수 있도록 전산시스템 구현가능성을 염두에 두고 구축하였다.

Purpose: The purpose of this study was to develop a resource-based relative value scale (RBRVS) and its conversion factor for advanced nursing practices carried out by critical care nurse practitioners (CCNP) in intensive care units. Methods: The methodology was developed by calculating CCNP's RBRVS for 32 advanced nursing services based on CCNP's workload and time spent in the context of national health insurance. A cost analysis was performed to estimate the conversion factor of CCNP's RBRVS. The share of CCNP's contribution to fee-for-service in intensive care units was also analyzed. Results: Calculation of the RBRVS of 32 advanced nursing practices showed a range of points from 100.0 to 1,181.4 and an average of 296.1 points. The relevant conversion factor for advanced nursing practices in CCNP were estimated at 37.3-48.4 won. The contribution rate of CCNP's advanced nursing practices in the relative value scale of the national health insurance was estimated at 0.1-31.3%. Conclusion: Measuring the economic value of advanced nursing services will be a basis for esta-blishing a reimbursement system for CCNP's practices and thus encourage a social demand for advanced nurse practitioners.

Purpose: The purpose of this study is to establish reliability and validity and to identify the conversion index. Method: The WMSCN for ICU was revised from Workload Management System for Nurses(WMSN) of Walter Reed Army Hospital. Reliability of the WMSCN was evaluated interrater reliability between head nurses and staff nurses at 124 patients in April 2008. Validity through the correlation between direct nursing care hours and WMSCN score was conducted at 20 ICUs of 10 hospitals. Finally the conversion index was identified by total nursing hours and it divided by WMSCN score. Results: The scores by nurses were highly correlated with head nurses’(p=.967), and also scores of the WMSCN were highly correlated with the direct nursing care hours(p<.001). The distribution of patient classification ranks into class V(61.3%), class IV(24.2%) and class VI(11.3%). The scores of the WMSCN were no differences between MICU and SICU. Finally, the conversion index was 8.2 minutes. Conclusion: WMSCN is available to classify the nursing workload for critical care patients. The repeated evaluation of validity and reliability are requisite to use WMSCN effectively. And the conversion index should be adjusted to estimate the appropriate staffing in Korea.

Purpose: This study was performed to verify reliability and validity of Korean Patient Classification System for nurses(KPCS-1), to estimate nursing time conversion index, and to classify patients into groups according to KPCS-1 scores. Methods: KPCS-1 was revised from KPCS by a professional review team. Interrater reliability and construct validity of KPCS-1 were verified by data from 433 patients. Direct and indirect nursing time of 204 patients were measured by stopwatch observation and self reports for 24 hours. Nursing time conversion index was calculated. Results: KPCS-1 consisted of 12 area, 50 nursing activities, and 73 items. The interrater reliability was tested between two nurse group (r=.88, p<.001) and construct validity was verified according to medical department (F=10.97, p<.001) and patient pattern (F=5.54, p=.001). The correlation of nursing time and classification score was also statistically significant (r=.56, p<.001). The nursing time conversion index was 9.03 minutes per 1 classification score. The patients were classified into 4 groups by the classification scores. Conclusion: KPCS-1 can be a useful factor type patient classification system for general ward. Further study is needed to evaluate validity and reliability for refining KPCS-1 and to develop ways connecting the scores with nursing outcomes.

Color indexes and effective temperatures for 25 standard stars have been determined as a pilot project which show a relationship between color index and effective temperature in ultraviolet region. The effective temperature was determined by comparing energy distribution curves derived from the IUE low dispersion spectra with Kurucz atmosphere model. The UV color index was deduced by integrating fluxes in $300{\AA}$ interval of the IUE low disperion spectra. The relation between color index and effective temperature in ultraviolet is similar with that of optical region.
