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.

우리나라의 경우 그동안 도로부문의 투자는 신규건설 그 자체가 정부 정책의 핵심이었다. 그러나 최근 정부의 도로부문 예산이 2000년을 정점으로 신규건설은 감소하고 유지관리는 증가하는 추세이다. 이러한 추세에서 도로 유지관리 예산 증가에 대한 정당성을 입증하면서 서비스수준에 대한 사용자 요구에 부응할 수 있는 새로운 도로정책 패러다임이 필요하다. 1950~60년대에 사회기반시설을 집중적으로 건설하였던 선진국들이 최근 공공시설물의 노후화에 대처하기 위해 자산관리 개념을 도입하여 많은 성과를 거두고 있다. 본 연구에서는 일반국도의 효율적인 유지관리를 위해 "한국형 도로 자산관리시스템"을 구축하는데 필요한 기본체계를 제시하였다. 이 시스템의 특징은 장기적이며 예방적인 도로 유지관리 정책을 수립할 수 있도록 기존의 포장관리시스템에 경제성 분석 과정을 포함시키는데 있다.

The water supply facilities of Korea have achieved a rapid growth, along with the other social infrastructures consisting a city, due to the phenomenon of urbanization according to economic development. Meanwhile, the level of water supply service demanded by consumer is also steadily getting higher in keeping with economic growth. However, as an adverse effect of rapid growth, the quantity of aged water supply pipes are increasing rapidly, Bursts caused by pipe aging brought about an enormous economic loss of about 6,161 billion won as of 2019. These problems are not only worsening water supply management, also increasing the regional gap in water supply services. The purpose of this study is to classify hazard evaluation indicators and to rank the water distribution network hazard by cluster using the TOPSIS method. In conclusion, in this study, the entropy-based multi-criteria decision-making methods was applied to rank the hazard management of the water distribution network, and the hazard management ranking for each cluster according to the water supply conditions of the county-level municipalities was determined according to the evaluation indicators of water outage, water leakage, and pipe aging. As such, the hazard ranking method proposed in this study can consider various factors that can impede the tap water supply service in the water distribution network from a macroscopic point of view, and it can be reflected in evaluating the degree of hazard management of the water distribution network from a preventive point of view. Also, it can be utilized in the implementation of the maintenance plan and water distribution network management project considering the equity of water supply service and the stability of service supply.

The purpose of the study was to compare patient's satisfaction on the pharmacy services after introducing the new system of separation of dispensing from prescribing medicines, between those filling their prescriptions from the pharmacy nearby hospitals and those from the pharmacy in their resident areas. To measure patient's satisfaction, a questionnaire survey was conducted with 354 outpatients who received prescriptions from any of the three university hospitals located in In-Cheon city. Study results showed that geographic accessibility to pharmacy was a main attribute to select pharmacy. Size of the pharmacy and availability of prescription drugs are the second major reasons for pharmacy selection for the patients from the pharmacy nearby hospital, whereas patronage is the second major reason for those from the pharmacy in resident areas. Overall satisfaction was higher among the patients from the pharmacy in resident areas than those from the pharmacy nearby hospitals, mainly due to better facilities(waiting area, public telephone, etc), kindness, cleanliness, shorter waiting time, and pharmacist's concern about patient's health. On the other hand, the patients of the pharmacy nearby hospitals showed low satisfaction because of long waiting time and the lack of pharmacist's knowledge and information about patients' health status and medication history. Patients visiting the hospital that has pharmacy-hospital cooperation system showed higher satisfaction as compared to those visiting the hospital without such system. This study provided an empirical evidence that it would be more advantageous for patients to receive pharmacy services from pharmacies located in their living areas than from pharmacies nearby hospitals. This implies that there is a strong need for adequate strategies to enhance the role of pharmacies in resident areas under the new system of separation of dispensing from prescribing medications.

산업시설의 대형, 첨단화에 따라 각 산업현장에서 다양한 종류의 유해 위험물질이 대량으로 사용되고 있다. 이에 따라 독성누출, 화재, 폭발 등의 중대산업사고가 지속적으로 발생되고 있으며 그 위험은 점점 높아지고 있는 실정이다. 여러 예방 시스템 중 Process Safety Management (PSM, 공정안전관리)제도가 있지만 아직까지도 제도의 취지와는 다르게 자율적인 운영보다는 해당 관청의 지도 점검에 맞추어 PSM 제도가 운영되고 있어 보이지 않는 중대위험이 잠재한 대규모 PSM 사업장의 안전성 확보에는 한계가 있다고 할 수 있다. 사업장의 안전시스템을 검증하기 위해서는 기존 시스템의 보완이 절실히 요구된다. 이에 본 연구에서는 PSM 자체감사의 중요성을 강조하고, 현재 제도의 문제점을 분석하여, 이에 대한 시스템 검증으로 제도 개선의 제안과 효율적인 자체감사 운영을 통해 자율 안전성을 강화하도록 하였으며, 또한 제도적으로도 이를 뒷받침할 수 있는 방법을 연구하여 제안하였다.

Objectives : The study enquires into OHB and its importance of preschooler mothers, based on perceived experiences of OHE. It also investigates mothers' sense of responsibility for children's oral health. The purpose is to enhance the effectiveness of OHE and its orientation. Methods : From April 20th to June 15th, 2011, 14 nurseries or preschools were randomly selected from childcare facilities of one gu(borough) in Busan. The objects of study are mothers of four to seven-year-old children. The collected survey data were analyzed using SPSS 12.0 for Windows. Results : 1. There is a statistically significant difference(p<0.01) in relations between the mothers' working status and perceived experiences on OHE. 2. On the survey about OHB practices, there are significant differences(p<0.001) in toothbrushing before breakfast, after meals, in three minutes and after refreshments Significant differences(p<0.01) are also shown in toothbrushing after eating fruits. 3. On the survey about the importance of OHB, there are statistical significances(p<0.001) in toothbrushing manner-rather than the number of it-toothbrushing in three minutes after meals and following the correct way of toothbrushing. There are also significant differences(p<0.05) in brushing teeth for more than three minutes. 4. There are significant differences(p<0.001) in mothers' periodic dental examination, children's periodic dental examination and training experience on children's toothbrushing. 5. On the survey about the sense of responsibility for children's OHE based on experiences of OHE, there is a significant difference(p<0.05) in that many replied OHEis "much-needed" regardless of their experiences on it. Conclusions : The results show that of infants' mothers, those with experience on OHE, have an accurate knowledge about toothbrushing, due to the effectiveness of the education. Both groups, however, replied that children's OHE is much needed, suggesting problems about the accessibility of the OHE.

Machines and facilities are physically or chemically degenerated by continuous usage. One of the results of this degeneration is the process mean shift. The representative type of the degeneration is wear of tool or machine. According to the increasing wear level, non-conforming products cost and quality loss cost are increasing simultaneously. Therefore a periodic preventive resetting the process is necessary. The total cost consists of three items: adjustment cost (or replacement cost), non-conforming cost due to product out of upper or lower limit specification, and quality loss cost due to difference from the process target value and the product characteristic value among the conforming products. In this case, the problem of determining the adjustment period or wear limit that minimizes the total cost is called the 'process mean shift' problem. It is assumed that both specifications are set and the wear level can be observed directly. In this study, we propose a new model integrating the quality loss cost, process variance, and production volume, which has been conducted in different fields in previous studies. In particular, for the change in production volume according to the increasing in wear level, we propose a generalized production quantity function g(w). This function can be applied to most processes and we fitted the g(w) to the model. The objective equation of this model is the total cost per unit wear, and the determining variables are the wear limit and initial process setting position that minimize the objective equation.

HPAI (High pathogenic avian influenza) which is a disease legally designated as an epidemic generally shows rapid spread of disease resulting in high mortality rate as well as severe economic damages. Because Korea is contiguous with China and southeast Asia where HPAI have occurred frequently, there is a high risk for HPAI outbreak. A prompt treatment against epidemics is most important for prevention of disease spread. The spread of HPAI should be considered by both direct and indirect contact as well as various spread factors including airborne spread. There are high risk of rapid propagation of HPAI flowing through the air because of collective farms mostly in Korea. Field experiments for the mechanism of disease spread have limitations such as unstable weather condition and difficulties in maintaining experimental conditions. In this study, therefore, computational fluid dynamics which has been actively used for mass transfer modeling were adapted. Korea has complex terrains and many livestock farms are located in the mountain regions. GIS numerical map was used to estimate spreads of virus attached aerosol by means of designing three dimensional complicated geometry including farm location, road network, related facilities. This can be used as back data in order to take preventive measures against HPAI occurrence and spread.
