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.

Recently, the Ministry of Strategy and Finance announced a plan to reduce the proportion of economic evaluation in non-metropolitan areas and strengthen balanced development evaluation through the reorganization of the preliminary feasibility study system. In addition, the social value of the quality of life, such as job, environment, and safety, which may be affected by the implementation of transportation facility investment projects, was reflected as the main item of policy evaluation. In this study, the ripple effect of the project in terms of social value was reviewed for the Gangil-Chuncheon. The effect of highway opening was investigated by reviewing the feasibility report, post-evaluation report, and statistical indicators. Recently, the Gangil-Chuncheon highway is getting used by around 110,000 people per day. The number of tourists in Chuncheon rapidly has increased from 5 million a year to more than 11 million now. In addition, it was confirmed to produce effects such as population migration, net inflow and land price increase, improvement of living convenience, and expansion of emergency medical care. Although this ripple effect was influenced by various socio-economic factors as well as the opening of the highway, it is clear that it is difficult to occur without the opening of the highway. It is judged that the evaluation of indirect benefits and social values due to the opening of the highway can be quantified through continuous research and data construction. Post-evaluation of construction works, including project efficiency evaluation and ripple effect evaluation, is performed for construction works with a construction cost of more than 50 billion won. In the future, we will continuously improve the evaluation system in order to evaluate the indirect benefits and social values of public investment projects.

This study is aiming at identifying the foreward and backward lingkage effects of the farm land base development project. Korean Government has continuously carried out farmland base development projets including the integrated agricultural development projects. large and medium scale irrigation projects and the comprehensive development of the four big river basin including tidal land reclamation and estuary dam construction for the all weather farming since 1962. the starting year of the five year economic development plans. Consequently the irrigation rate of paddy fields in Korea reached to 75% in 1998 and to escalate the irrigation rate, the Government had procured heavy investment fund from IBRD. IMF and OECF etc. To cope with the agricultural problems like trade liberalization in accordance with WTO policy, the government has tried to solve such problems as new farmland base development policy, preservation of the farmland and expansion of farmland to meet self-sufficiency of foods in the future. Especially, farmland base development projects have been challanged to environmental and ecological problems in evaluating economic benefits and costs where the value of non-market goods have not been included in those. Up to data, in evaluating benefits and costs of the projects, farmland base development projects have been confined to direct incremental value of farm products and it's related costs. Therefore the projects'efficiency as a decision making criteria has shown the low level of economic efficiencies. In estimating economic efficiencies including Leontiefs input-output analysis of the projects could not be founded in Korea at present. Accordingly this study is aimed at achieving and identifying the following objectives. (1) To identify the problems related to the financial supports of the Government in implementing the proposed projects. (2) To estimated backward and foreward linkage effects of the proposed project from the view point of national economy as a whole. To achieve the objectives, Hwangrak benefited area with reservoir which is located in Seosan-haemi Disticts, Chungnam Province were selected as a case study. The main results of the study are summarized as follows : a. The present value of investment and O & M cost were amounted to 3,510million won and the present value of the value added in related industries was estimated at 5.913million won for the period of economic life of 70 years. b. The total discounted value of farm products in the concerned industries derived by the project was estimated at 10,495million won and the foreward and backward linkage effects of the project were amounted to 6,760 and 5,126million won respectively. c. The total number of employment opportunities derived from the related industries for the period of project life were 3,136 man/year. d. Farmland base development projects were showed that the backward linkage effects estimated by index of the sensitivity dispersion were larger than the forward linkage effect estimated by index of the power of dispersion. On the other hand, the forward linkage effect of rice production value during project life was larger than the backward linkage effect e. The rate of creation of new job opportunity by means of implementing civil engineering works were shown high in itself rather than any other fields. and the linkage effects of production of the project investment were mainly derived from the metal and non-metal fields. f. According to the industrial linkage effect analysis, farmland base development projects were identified economically feasible from the view point of national economy as a whole even though the economic efficiencies of the project was outstandingly decreased owing to delaying construction period and increasing project costs.

In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

The failures of tailing dams have caused irreparable damage to human lives, assets and environment and this has ultimately resulted in great economic, social and environmental challenges worldwide. Due to this, investigation into mechanical behaviour of tailings has received some attention. However, the knowledge and understanding of mechanics of behaviour in iron tailings is still limited. This study investigates the mechanics of iron tailings from Nigeria considering grading, effects of fabric resulting from different sample preparations and the possibility of non-convergent behaviour. This was achieved by conducting series of one-dimensional compression tests in conjunction with index, microstructural, chemical and mineralogical tests. The materials are predominantly poorly graded, non-clayey and non-plastic. The tailings are characterised by angular particles with no obvious particle aggregations and dominated by silicon, iron, aluminium, haematite and quartz. The compression paths do not converge and unique normal compression lines are not found and this is an important feature of the transitional mode of behaviour. The behaviour of these iron tailings therefore depends on initial specific volume. The preparation methods also have effect on the compression paths of the samples. The gradings of the samples have an influence on the degree of transitional behaviour but the preparation methods do affect the degree of convergence. The transitional mode of behaviour in these iron tailings investigated is very strong.

Diphenyl-2-ethanolamidophosphate (DPEOAP) was synthesized to treat polyester fabrics in order to improve its flame retardancy. The flame retardancy and physical properties of DPEOAP-treated polyester fabrics were investigated. The results were as follows: 1) polyester fabrics can be treated with DPEOAP by means of Pad-Dry-Cure method, because DPEOAP was easily soluble in benzene. 2) The most economic conditions of treatment were determined as 10% of DPEOAP cocentration, $140^{\circ}C$ of curing temperature, and 2 minutes of curing time. 3) Though the washablity of DPEOAP is low in comparison with the other products which are purchasable in a market, it has an excellent flame retardment effect 3 times more than in number of flame contact just with 0.66% add-on. 4) The physical properties of DPEOAP treated polyester fabrics were little changed as compared with non-treated fabric.

경제활동공간이 역동적으로 변화하고 있다. 특히 서울시 성동구 성수동 지역은 제조업 집적지였지만, 현재 급격한 변화를 겪고 있는 대표적인 지역 중 하나라고 할 수 있다. 성수동 지역은 도심 제조업이 쇠퇴하면서 공장 이전이나 폐업으로 인한 빈 공간에 새로운 행위자가 유입되고 있다. 이러한 행위자들은 전통적인 접근법에서는 다소 간과되었던 비경제적 행위자인 문화예술 부문의 창조적 행위자들이며, 이들의 비공식적인 모임인 문화예술 인식공동체는 생태계 형성 초기에 지역 생태계가 창조적 환경으로 변화하는데 영향을 끼친 것으로 보인다. 본 연구의 목적은 도시 공간구조 변화 메커니즘의 근본적인 동인을 규명하여 공간적 함의를 도출하고자 하는 것이며, 이를 위해 진화적인 관점에서 인식공동체의 단계별 형성과정에 따라 초기 문화예술 기반의 창조적인 지식생태계의 형성과정과 추동요인을 고찰하고자 하였다. 그 결과, 인식공동체는 진화적인 경로 창출과정에서 지역 프로젝트를 진행하며 지식창출을 위한 지식플랫폼으로서 일시적인 공간 형성에 기여했고, 성수동 지역은 공간적 근접성을 넘어 관계적 근접성을 추구하며 관계적 공간을 형성하고 있는 것으로 나타났다.

교육훈련의 경제적 효과에 대해서 한국노동패널을 자료를 이용하여 개인별로 살펴본 결과 본고에서는 다음과 같은 결과를 얻을 수 있었다. 교육훈련의 임금효과는 근속의 두 배에 조금 미칠 정도로 크고 유의하게 나타난다. 교육훈련은 직무내용과 고용안정, 성장 가능성의 만족에 크고 유의한 양의 효과를 갖는 것으로 나타난다. 선택편의를 통제하기 위해 임금함수의 1계차분으로 추정한 교육훈련의 임금효과는 유의하지 않다. 그러나 계속근속자와 이직경험자의 샘플로 나누어 추정하면 계속근속자의 교육훈련의 임금효과는 유의하지 않으나, 이직 경험자의 교육훈련 임금효과는 크고 유의하게 나타난다. 보다 구체적으로 기업의 비용을 부담한 교육훈련의 효과를 보면 이직 경험자의 교육훈련 임금효과는 그고 유의하게 나타나나, 계속근속자의 교육훈련 임금효과는 작고 유의하지 않게 나타난다. 이는 사용자들이 재직근로자가 교육훈련을 이수한 경우 그에 따라 임금을 올려 주지 않은 결과이다. 기업이 비용부담을 하는 경우에 교육훈련으로 인한 생산성 증가만큼 임금 증가가 이루어지지 않는 것은, 결국 기업이 교육훈련 비용부담을 개별 근로자들에게 전가하고 있음을 나타낸다고 할 수 있다.
