Objectives : The purpose of this study was to find factors affecting the cost-reduction practice of clinical nurses. Methods : The Data were collected from Feb. 25, to Mar. 15, 2015.the Total subjects were 201 nurses working in secondary-care hospitals located in Busan Results : The Meaningful variables that explain the cost-reduction practice in clinical nurses were psychological ownership, religion, and marital status in that order. Total explanation power was 22.1.% and psychological ownership has most explanation power. Conclusions : Psychological ownership and economic consciousness need to improve to develop cost-reduction practices. Additionally, nurses with and low concern about finances need to receive financial-related education.

건설사업의 목표는 해당 사업의 특성에 따라 우선순위의 차이는 있지만 기본적으로 원가절감, 공기단축, 품질확보로 압축될 수 있다. 그 중 원가절감은 발주자와 건설산업계 모두에게 중요한 목표이며 이를 달성하기 위한 전략과 방법은 중요한 관심사라 하겠다. 원가절감은 사업범위, 품질, 안전, 상호 비즈니스 관계, 고객만족 등 타 매니지먼트 요소의 희생을 수반함으로써 부정적인 이미지로 인식되어 왔다. 그러나 원가절감이란 용어는 부정적인 이미지를 극복하고 가치창조(value for money)를 달성시키는 긍정적인 방향으로 변화하여야 할 것이다. 본 연구에서는 영국 Constructing Excellence의 성공사례를 중심으로 원가절감의 성공사례 분석을 동하여 긍정적인 원가절감 전략의 특징을 도출하고자한다.

Seven diagnosis-related groups (DRGs) prospective payment system is going to expand to all hospitals including university hospitals this year. However there are few studies on the change of practice pattern under prospective payment system in the university hospital setting. So This study was intended to predict the practice pattern change after the introduction of 7 DRGs prospective payment system in a university hospital setting. To predict the change of practice pattern, this study used simulation technique. Five hundred and nineteen patients classified as 5 DRGs in a university hospital were selected for simulation. The change of practice pattern were predicted based on clinicians' opinion. We also predicted payment change by service items. Major findings of this study are as follows. First, the total medical payment was reduced by 14.4%. The drug payment change (8.8%) took most of total payment reduction. The followings are the change of treatment material cost (3.2%), the change of laboratory tests cost (1.8%), the change of room charge (0.5%), and other payment change (0.1%), respectively. Second, most of the reduction in total medical payment resulted from the decreased amount of medical services themselves. The transfer of medical services to outpatient setting took up only 4.9% of the total payment reduction. The change of unit price or composition took up 5.5% of the total payment reduction. In this study we found that it is possible to reduce the inpatient services through practice pattern change in university hospital setting. However, it needs to be careful to adjust DRG payment after the reduction of provided services, because most of reduction was not due to service transfer but to service volume reduction. It is desirable to utilize the saving from practice pattern change as incentive to improve quality of care.

본 연구는 산림작업이 지속적으로 이루어진 5개 지방청 8개 경영계획구를 대상으로 조림 및 숲가꾸기 작업에서 임도시설 전 후의 접근성과 산림작업비용의 절감효과를 분석하였다. 분석 결과, 임도 및 공도로부터 500 m 이내의 사업실행 면적이 임도 시설 전 평균 28.5%에서 임도 시설 후 평균 90.3%로 약 3.2배 증가하였으며, 임도 시설에 따른 조림 및 숲가꾸기 작업에서의 산림작업비용 절감효과는 평균 576천원/km/년인 것으로 나타났다. 따라서 임도시설이 원활한 산림작업을 위한 접근성 개선 및 작업비용 절감효과가 있는 것으로 나타났으며, 임도의 시설효과 분석을 통해 임도 확충 정책의 추진을 위한 기초자료의 제공이 가능할 것으로 판단된다.

본 연구는 임도의 목재수확작업에서의 활용효과에 대한 실증적 구명을 위해 5개 지방산림청 8개 경영계획구의 실행자료를 토대로 목재수확작업에서의 임도시설 전 후의 접근성 변화와 비용절감 효과를 분석하였다. 분석 결과, 임도 및 공도로부터 500 m 이내 목재수확 작업의 사업실행 면적은 임도 시설 전 평균 25.2%에서 시설 후 평균 88.3%로 약 3.5배 증가하였으며, 임도 시설에 따른 목재수확작업 비용 절감효과는 평균 308천원/km/년인 것으로 나타났다. 이에 임도시설이 목재수확작업을 위한 접근성 개선 및 작업비용 절감효과가 큰 것으로 나타났으며, 임도 시설확충을 위한 지속적 정책추진이 필요할 것으로 판단된다.

Since the transportation cost takes two thirds of the logistics cost of Korean firms, significant reduction of business logistics cost can hardly be achieved without effective reduction of the transportation cost. Although consolidated transportation has been regarded as the most promising strategy for reducing the transportation cost, it has not been successful in practice. In this paper, we propose a consolidated transportation model for firms located in industrial complexes, present a heuristic algorithm to operate the system, and analyze the expected cost reduction.

Intelligent investment in setup cost reduction and process reliability improvement is crucial to an emerging integrated lean six sigma practice today. This study examines a cost-minimizing problem of jointly determining production lot size, setup cost reduction, and process reliability improvement decisions for a manufacturer with an imperfect production process. We develop models for previously untapped discrete shipping in a supply chain context as well as continuous shipping and solve them optimally using differential calculus and nonlinear programming. We also conduct analytic and numerical sensitivity analyses to provide various important managerial insights into practices.

In this study, based on the principal-agent paradigm, we investigate a joint cost reduction activity in a buyer-supplier supply chain where a buyer motivates its operations department and a supplier to reduce the supply chain's production cost. We construct a benefit-sharing model based on the target cost scheme, a basic philosophy in practice which has not been explored in previous studies. The model also incorporates various supply chain issues such as the cooperation of multiple agents, the opportunity loss, and the degree of strategic relationship between the buyer and the supplier. Based on the analysis of the principal-agent model, we investigate the benefit-sharing rule to control agents' actions, and we also provide important managerial implications into supply chain practices via extensive comparative static analyses.

본 연구는 전문지식을 갖지 않은 건설기술자와 건설사업 참여자가 건설 실무에서 중요도가 높은 단어와 단어 간의 상호 연관관계를 쉽게 이해할 수 있도록 정보서비스를 개선하고자 하였다. 이를 위해 텍스트마이닝과 네트워크 중심성을 이용하여 건설기술정보시스템에서 가장 많이 사용하고 있는 기술정보, 사례정보 및 원가절감 등 건설실무정보에 대해 단어의 출현 빈도, 주제 모형화, 네트워크 중심성을 분석하였다. 이러한 분석을 통해 도로, 포장, 교량, 터널 등 도로공사와 관련한 설계, 시공, 사업관리, 시방·기준, 유지관리 등이 건설 실무에서 중요한 정보로 파악되었다. 또한, 연결 중심성과 고유벡터 중심성 측정을 통해 중요도가 높은 단어 간의 상관도를 분석하였다. 상관도 분석을 통해 기술정보를 확충한다면 보다 유용한 정보를 제공할 수 있다는 결과를 얻었다. 끝으로, 연구 결과가 갖는 제약과 이에 따른 추가적인 연구를 제시하였다.

Since the transportation cost takes about two thirds of the logistics cost of Korean firms, significant reduction of business logistics cost can hardly be achieved without effectively reducing the transportation cost. Although consolidated transportation has been regarded as the most promising strategy for reducing the transportation cost, it has not been successful in practice. In this paper we consider a consolidated transportation for the factories located in a limited area such as industrial complexes, where loads of various volume and weight are consolidated. We want to group the loads to assign to a truck of various size such that the total transportation cost is minimized, while the maximum volume constraint and weight constraint of each truck are satisfied. We suggest four heuristic algorithms to efficiently determine the groups of loads; and conduct a computer simulation to evaluate the performances of the algorithms.
