This article describes a 2-in-1 methodology utilizing simulation optimization technique and Data Envelopment Analysis in measuring an accurate efficiency score. Given the high level of stochastic data in real environment, a novel methodology known as Data Collection Budget Allocation-Data Envelopment Analysis (DCBA-DEA) is developed. An example of the method application is shown in banking institutions. In addition to the novel approach presented, this article provides a new insight to the application domain of efficiency measurement as well as the way one conducts efficiency study.

본 연구에서는 현재 국내 공공도서관 자료선정업무의 현황을 자료구입비 규모, 자료선정정책과 자료선정기준, 자료선정 담당 인력과 자료선정위원회, 자료선정방법과 자료선정도구 등의 카테고리로 나누어 살펴 본 다음 사서들의 자료선정업무에 대한 인식을 조사하였다. 이러한 현황을 바탕으로 효율적인 자료선정이 이루어질 수 있는 방안을 자료선정정책, 자료선정인력, 자료선정방법의 세 가지 측면으로 나누어 논의하였다. 자료선정업무현황 분석을 위한 데이터 수집은 국내 공립공공도서관 315개관을 대상으로 한 설문조사를 통하여 이루어졌다.

정부 재정지출의 효율성 제고를 위해 도입된 총사업비관리제도는 그간 대형 신규 공공투자사업 추진 시 적정한 절차를 순차적으로 거치도록 의무화하고, 총사업비 증가율을 억제하는 등 일부 성과가 있었다. 도입 18년이 지난 시점에서 공공건설사업의 사업비 관리의 근간이 되는 총사업비관리제도에 대한 적용 실태 및 제반 운영에 대한 사업참여자들의 인식을 조사하고, 설문을 통하여 운영상의 문제점을 도출하여 이에 대한 개선방안을 제시하였다. 기본적으로 공공건설사업의 사업비 관리는 사업 초기 단계에 예산을 정확히 산정하고, 후속 단계에서 이를 지키려는 노력을 시행하며, 확정된 예산에 가장 부합하는 사업의 가치 확보라는 개념에 입각해서 계획하고 관리하여야 한다. 공공건설사업의 총사업비관리의 체계화하고, 담당자의 전문성을 제고하는 한편 발주처의 자율성을 확대하여야한다. 무엇보다도 총사업비관리 대상사업의 적기 준공을 유도하여 사업기간 지연으로 인한 총사업비의 증액을 방지 할 수 있는 여건 조성이 필요하다.

It is necessary to calculate prime cost of medical services accurately in order to evaluate the adequacy of medical fee. This paper aims to identify cost analysts' perception on prime cost of medical services and needs in establishing a cost accounting system in hospitals, proposing future directions and guidelines for the calculation of medical fee. A self-administered questionnaire and telephone survey on operation of a hospital cost-accounting system was conducted in November, 2012, among cost analysts currently working in the hospitals and hospital administrators planning to implement the hospital cost-accounting system. Our study shows that most of the cost analysts were aware of the importance of calculating prime cost and responded that collection of the prime cost data from government is necessary although they are less likely to provide the data in the future concerning the risk of data misuse and data security. They also responded that lack of budget allocation and excessive workload were the main reasons for not estimating the prime cost and operating cost management information system. Results show that hospital cost analysts considered the data accuracy is the most critical factor in calculating prime costs of medical services. However, there was no investment budget allocated in some hospitals or limited to less than 100 million, indicating that hospitals are reluctant to invest on implementing the cost accounting system. Respondents stated the organization that collects the prime cost of medical services among hospitals should display strong analytical capabilities, ensure data security, and maintain independence, which is most demanded. There are 57 hospitals that calculated the prime cost of medical services for 2012 by each medical department and 20 hospitals that calculated the prime cost by fee-for-services, aiming to establish a cost accounting system. Our results indicate that hospitals should voluntarily provide the accurate prime cost for medical services in order to properly evaluate the adequacy of medical fee. Consequently, it is critical to establish an independent organization to collect and appraise the data. It is also recommended that government should implement various policies to encourage hospitals to participate in the data collection to achieve the data accuracy and representativeness.

Background: The gelada baboon, Theropithecus gelada Ruppell, 1835, is an endemic primate of the central and western highlands of Ethiopia occurring between altitudes of 1800-4400 m. Variability in activity time budget between the two gelada social units, i.e., one-male units (OMUs) and all-male units (AMUs), has not been studied previously. Thus, the present study was an effort to understand intra- and inter-variations in group size and daily activity time budget in gelada baboon OMUs and AMUs at Guassa Community Conservation Area, Central Ethiopia. The instantaneous sampling method was used in the data collection. Results: Both OMU and AMU groups allocated more time for feeding (OMUs = 36.96%; AMUs = 35%) followed by moving (OMU = 25.8%; AMUs = 27%). Grooming was the most frequent social activity in both family groups (OMUs = 8.56%; AMUs = 11.81%). OMUs and AMUs did not show significant variation between themselves in the time budget and temporal distribution of their daily activities. However, the overall variation in the time budget allocated for daily activities within OMUs and AMUs was statistically significant (p < 0.05%). The different age and sex groups in OMUs (i.e., immature, sub-adult females, subordinate males, adult females, and alpha males) showed statistically significant variation in their time budget allocation for the daily activities (p < 0.05) except for feeding and moving. Alpha males had the highest proportion of resting (32.14%) and aggression (31.92%). Immature individuals were responsible for > 90% of the time budget recorded for playing while adult females showed the highest frequency of grooming. Group size of OMUs ranged between 5 and 15 individuals (mean ± SD = 11.25 ± 1.95). Adult females comprised the highest number within OMUs (mean = 4.5) followed by immature individuals (mean = 3). The group size of AMUs ranged from 4 to 8 (mean ± SD = 6.6 ± 1.5). Conclusion: Our results showed that the gelada baboon spent less time on foraging compared to previous studies at the Simien Mountains and Debre-Libanos area. We suggested this variation could be explained based on higher forage quality at Guassa Community Conservation Area resulting from better conservation of the habitat.

This Study carried out for the purpose of basic data collection school teachers in Korea during September 2000 at Seoul, Kangwon province and JeonRaBuk province. 534 teachers among 600 school health teachers was analyzed by SPSS program. The major findings is as follows; 1. Mean score of Job-satisfaction is $25.52{\pm}4.46$ as 50 total point. Staff cooperation $2.96{\pm}.93$ is the highest score and promotion system $2.02{\pm}1.06$ is the lowest score as 5 total point by Job-satisfaction factor 2. Age-specific mean scores are $20.63{\pm}4.44$ at age of $20{\sim}29$, $25.77{\pm}4.15$ at age of $30{\sim}39$, $27.69{\pm}4.63$ at age of $40{\sim}49$ and $27.11{\pm}5.26$ at age of more than 50.

Job-satisfaction of long period working teachers is higher than that of short workers, 'Salary system' and 'Professional skill' by factor are significantly different. 4. Job satisfaction by area is not significantly different, and 'Professional skill' as a factor of urban is higher than rural area. 5. Job-satisfaction by school level is not significantly different, and 'Health budget', 'Cooperation of school physician', 'Allocation of professional' and 'Professional skill' are significantly different by level of school. 6. Job-satisfaction of big size school is higher than that of small school and 'Health education' of big size school is high. 7. Job-satisfaction of low education is low score and 'Salary', 'Textbook for health education', 'Health facility' and 'Professional skill' are differnt. 8. 'Educational background', 'Size of school' and 'Level of school' are significantly affected to 'Salary system', this three varialbles explained 13.8% of the total. We can express job -satisfaction of 'Salary system' ; y=2.677-$.182X_6$(Education)+$.120X_5$(Size of school)+$.019X_4$(Level of school) 9.

홍수는 다양한 원인으로 발생할 수 있으며, 주로 내수배제 불량이나 외수범람을 홍수의 주요 원인으로 주목하고 있으며, 대규모 유역 유출을 발생시키는 강우 또한 빈번히 발생하고 있는 실정이다. 기존의 홍수위험지도는 수리·수문학적 모델링을 통한 분석을 기반으로 하여 방대한 자료의 수집과 복잡한 분석과정으로 인한 장시간의 소요시간으로 넓은 지역에 대한 홍수위험지도 작성이 어려운 실정이다. 본 연구에서는 이를 극복하고자 홍수위험도 산정 시 필요한 시간과 노력을 절감하고 광범위한 지역에 대한 세밀한 분석을 실시하기 위해 지표유출메커니즘을 고려한 홍수취약지구 선정 기법을 제안하고자 한다. 홍수취약지구 선정 기법을 대상지역인 서울시에 적용하여 2×2 혼동행렬과 ROC(Receiver Operation Characteristic) 곡선을 활용하여 검증함으로써 선정된 취약지구 인근에서 침수피해가 발생하기 쉽다는 것을 확인할 수 있었다. 본 연구의 결과를 이용하여 관리 우선순위를 반영하여 효율적인 예산 배분과 체계적인 방재대책 수립이 가능할 것으로 판단된다.
