The purpose of this study is to implement and develop the integrated Economic Value Added (EVA) and Time-Driven Activity-Based Costing (TDABC) model to seek both improvement of Net Operating Profit Less Adjusted Tax (NOPLAT) and reduction of Capital Charge (CC). Net Operating Profit Less Adjusted Tax (NOPLAT) can be maximized by reducing the indirect cost of an unused resource capacity increased by Cost Capacity Ratio (CCR) of TDABC. On the other hand, Capital Charge (CC) can be minimized by improving the efficiency of Invested Capital (IC) considered by Weighted Average Cost of Capital (WACC) of EVA. In addition, the integrated system of TDABC using Balance Scorecard (BSC) and EVA is developed by linking between the lagging indicators and the three leading indicators. The three leading indicators include customer, internal process and growth and learning perspectives whereas the lagging indicator includes NOPLAT and CC in terms of financial perspective. When the Critical Success Factor (CSF) of BSC is cascading as a cause and an effect relationship, time driver of TDABC and capital driver of EVA can be used efficiently as Key Performance Indicator (KPI) of BSC. For a better understanding of the proposed EVA/TDABC model and BSC/EVA/TDABC model, numerical examples are derived from this paper. From the proposed model, the time driver of TDABC and the capital driver of EVA are known to lessen indirect cost from comprehensive income statement when increasing the efficiency of operating IC from the statement of financial position with unified KPI cascading of aligned BSC CSFs.

원가 및 관리회계분야에서는 이미 선진국을 중심으로 활동개념을 도입한 활동기준 원가 계산(ABC : activity-based costing)이 성공적으로 도입·운영되고 있다. 하지만 국내외 적으로 재무회계분야에서는 전통적으로 복식부기시스템(double-entry bookkeeping system)에 지나치게 편중되어 있어서 회계정보의 산출과정에서 여러 가지 제약을 받고 있 는 것도 사실이다. 이러한 문제점을 개선·보완하기 위해서 재무회계 분야에도 활동개념을 도입했는데, 이것이 바로 활동정보회계(AIA : activity information accounting)이다. AIA는 기업의 활동이 발생하는 즉시 복식부기처리과정을 거치지 않고 활동과 대응가치의 처리방법 을 통해 실시간으로 회계정보를 생산하며, 기업의 모든 부서가 정보를 즉시 공유하고 교류 함으로써 기업유기체를 가능케 하는 새로운 회?리방법론이다. AIA의 개념을 구현하기 위해 이스턴컨설팅(주)에 의해서 개발된 활동정보회계시스템(activity information accounting system)은 복식부기시스템을 전면 부정하기 보다는 이를 점자 개선하고 보완하려는 의도에 서 개발된 종합회계처리프로그램이며, 따라서 복식부기의 모든 회계처리과정을 누락시키지 않으면서도 다양 회계, 관리 및 경영분석보고서를 제공해준다.

The main purpose of this study is to compare the traditional cost system and ABC(Activity Based Cost) system of clinical laboratory department in a hospital. The study subject was 296 services in clinical laboratory from March, 1997 to August, 1997. In a new costing system, cost for a lab test consist of direct cost element, activity based cost element, and allocated common cost element. In a traditional cost system, cost elements included direct cost element and indirect cost allocated based on test volumes The major findings of this research were as follows. 1. In the application of ABC system, total cost was analyzed as follows. Direct cost was 39.3% of total cost. Activity cost and allocation were 20.9% and 39.8%, respectively. The results of analysis to use traditional cost system were as follows. Direct cost was 39.3% and it was as same as the result of direct cost of ABC system. Indirect cost was 60.7%. 2. Activities of clinical laboratory of subject hospital were registration, pre-test operation, test, test result handling, delivery, culture, post-test operation, technical support, management support, and educational support. 3. The differences of the case of higher number of test case being carried out, the cost of ABC system was lower than the cost of traditional cost system. Otherwise in the case of lower number of test case being carried out, the rests have not been appropriately evaluated, and effective management were needed in clinical laboratory.

Various trials to overcome the limitation of current accounting which fails in synchronizing business activities and their information have failed to make satisfactory result merely showing a little saving of processing time. This is because such trials have been done within the boundary of double-entry bookkeeping system. Without consolidating business activities and their information, reformation efforts such as BPR(business process re-engineering), ABC(activity-based costing), CALS(commerce at light speed) etc to fit the business organization to the changing business environment could not be achieved. Overcoming the limitation of accounting takes precedence of any other attempt to construct the management information systems. Activity Information Accounting System(AIAS) proposes the way of overcoming the limitation of current accounting by using the new accounting methodology and unique solution to real time accounting information. AIAS produces accounting and management information directly of activity information without bookkeeping process of activity information. AIAS adopts method of transforming the details of corporation activities directly into accounting information rather than method of double-entry bookkeeping system. The purpose of this paper is to prove AIAS to be very flexible system by using flexibility concepts. Flexibilities are defined as three aspects, namely ① timeliness (rapid accounting information generations and presentations) ② easy systems modificabilities according to environment changes ③ adaptabilities to all industries.

Terminal market has rapidly crashed and market rates have taken a sharp plunge. The substantial throughput decrease resulted from the world economic downturn has been a finishing blow to the terminal operators in Busan. Every terminal operator is taking cost saving as its first priority and accelerating structural reform and downsizing. Under the desperate situation, the need of effective cost analysis would be highly required to effectively control operation cost and to develop new services to satisfy the different needs of the customers. Furthermore, terminal operators could reduce unnecessary activities and concentrate their resource on the more cost-effective process through the operation cost analysis. In order to suggest a new framework of the cost control of container terminals, this paper seeks to analyze terminal costs based on ABC approach by processing actual data.

This study tries to apply standard cost accounting model to evaluate the cost of workflow instances. Previous studies mainly focus on matching workflow activities into the elements of Activity based costing in order to assign cost drivers, but rarely examine how to evaluate their instance cost. In this study, we estimate unrealized standard cost from workflow model, and realized cost from accomplished instances. On running, workflow engine cumulates cost of finished activities and it enables to monitor the difference between the target cost and the actual cost dynamically at each step of workflow processes. We implemented a prototype which shows that the proposed work can evaluate effectively the cost of various workflow patterns.

This research introduces the Financial Effect Measurement (FEM) models which measures both the improvement and the innovation performance of Quality Control Circle (QCC) and activities of Six Sigma. Concepts and principle of Comprehensive Income Statement (CIS), Balanced Scorecard (BSC), Time-Driven Activity Based-Costing (TDABC) and Total Productive Maintenance (TPM) are applied in order to develop the 4 FEM models presented in this paper. First of all, FEM using CIS depicts the improvement effects of production capacity and yield using relationships between demand and supply, and line balancing efficiency between bottleneck process and non-bottleneck processes. Secondly, cause-and-effect relation of Key Performance Indicator (KPI) is used to present Critical Success Factor (CSF) effects for QC Story 15 steps of QCC and DMAIC (Define, Measure, Analyze, Improve, and Control) of Six Sigma. The next is FEM model for service management innovation activities that uses TDABC to calculate the time-driven effect for improving the indirect activities according to the cost object. Lastly, FEM model for TPM activities presents the interpretation of improvement effect model of TPM Capital Expenditure (CAPEX) and Operating Expenditure (OPEX) maintenance using profit, cash and Economic Added Value (EVA) as metrics of enterprise values. To better understand and further investigate FEMs, recent cases on National Quality Circle Contest are used to evaluate new financial effect measurement developed in this paper.

Purpose: This study was carried out to deveop nursing costs and to substantiate the application of appropriate activity-based nursing costs for the current clinical nurse specialists. Method: The study sample was a group of 8 home health care team of the tirtiary Hospital in Korea. The data was collected from September 2003 through December 2004. The statistical analysis was done by SPSS PC 11.0 program and calculated mean and the standard deviation. In Lee(2003)'s nursing activity analysis, nursing activities were classified into two major classification, 19 domains and 70 activities. Each activities was calculated using its work validity, physical effort, psychological effort, stress as a intensity, and the necessary time. The simple work costs was calculated the work wage per minute and the necessary time. The work load intensity was calculated using the work wage per minute and the necessary time work load intensity/100. Results: In this study, the work wage was 283 won per minute. The work validity ranged from 2.71-4.00. The highest simple work cost/work load intensity cost was 12,735won/47,374won for research activity, 10,700won/27,499won for bedsore care, and 9,727won/35,114won for deathbed care. The lowest simple work cost/work load intensity cost was 2,123won/2,038won for intramuscular injection, 2,210won/2,166won for hypodermic injection, and 2,210won/1,547won for a application of medicine(or ointment or cream). Conclusions: It revealed that the nursing cost should be considered validity, physical effort, psychological effort, stress as a intensity, and necessary time. Therefore, It is necessary to calculate nursing cost systematically based on activities.

There is no doubt that BSC(Balanced Scorecard), ABC(Activity-Based Costing System), EVA(Economic Value Added System) draw sensation in the world as the tools of Performance Evaluation System and Quality Control. They are useful tools that can help succeed in the dynamic and competitive business environment. These three tools are discussed respectably. However, it also brings doubt whether it is possible to integrate the three tools made in the similar time and which way is appropriate among the three tools according to the type and the circumstance of business. In fact, these tools are not the opposing relations but the complementary relations. Consequently, this paper explains the relations of the three methods and suggests the process of the integrated models. Besides, it provides an idea about when Performance Evaluation System and Quality Control are needed for companies under different aspects considering the circumstance used the respective methods individually.
