Among service industries of knowledge based economic era, the roles of educational service field are becoming more important and standard of educational service makes a direct effect on economic development and social growth. Therefore, accurate measurement of service quality is the most important assignment and the measurement of the service quality remains difficult assignment. So, this researcher classified quality attributes applying weighted value and found potential satisfaction level(PSL) and potential customer demand improvement index(PCDI) for trainees participating in national manpower business so as to suggest measurement of service quality and easiness of use and then, calculated satisfaction position and opportunity cost by quality factor with Taguchi's loss fraction. And, improvable satisfaction level was measured, opportunity cost by degree of customer dissatisfaction was quantitatively measured, and a model that can indicate with economic factors was suggested. In addition, methodology of measuring quality cost that can be reduced by quality improvement and direction of strategic decision-making for deciding items to be improved preferentially were suggested with qualitative index that can indicate the degree of customers' dissatisfaction by loss.

Evaluation method of soil fertility by combination of soil color characteristics and survey data from soil map as well as chemical properties was investigated on total 35 field and pot experiments. Total 35 tobacco fields including 11 fields located at Cheonweon county in Chungnam Province, 9 fields located at Goesan county in Chungbuk Province, and 15 fields located at Youngcheon county in Kyongbuk Province were selected in 1984 to cover the wide range of distribution in landscape and soil attributes. Yields of tobacco grown on the plots of both the pot and field experiment which were not applied with any fertilizer were considered as basic fertility of the soil (BFS). The BFS was estimated by 32 independent variables including 15 chemical properties, 3 color characteristics, and 14 soil survey data from soil map. Twenty-four independent variables containing 16 quantitative variables selected from 24 quantitative variables by collinearity diagnostics and 8 qualitative variables, were classified and analyzed by multiple linear regression (MLR) of REG and GLM models of SAS. Tobacco yield of field experiment showed high variations by eight times in difference between minimum and maximum yield indicating the diverse soil fertility among the experimental fields. Evaluation for the BFS by the MLR including quantitative variables was still more confidential than that by a single index and that showed more improvement of coefficient of determination ($R^2$) in pot experiment than in field experiment. Evaluation for the BFS by MLR in field experiment was still improved by adding qualitative variables as well as quantitative variables. The variability in the BFS of field experiment was explained 43.2% by quantitative variables and 67.95% by adding both the quantitative and qualitative variables compared with 21.7% by simple regression with NO$_3$-N content in soil. The regression evaluation for the best evaluation of the BFS of field experiment by MLR included NO$_3$-N content, L value, and a value of soil color as quantitative variables and available soil depth and topography as qualitative variables. Consequently, it is assumed that this approach by the MLR including both the quantitative and qualitative variables was available as an evaluation model of soil fertility for tobacco field.

There are big differences in six sigma applications between manufacturing processes and transactional processes. This paper analyzes the differences between two areas by examining 18 six sigma case studies in Korean companies. To characterize six sigma cases, a step-by-step checklist is developed based on 12-step DMAIC methodology proposed by US six sigma academy. On the basis of those characterized data, the differences between two areas are analyzed. The most significant differences is that statistical tools are widely used in manufacturing processes, but qualitative tools are used in transactional processes during improvement phase.

In this paper, a sensitivity analysis is proceeded to improve the network of manufacturing process by converting the qualitative network into GERT Network and by finding equivalent probability, MFG's of variables and sensitivity equation in GERT Network. Sensitivity analysis of GERT Network is important in evaluating, reviewing and improving system. System improvement in GERT Network is achieved by increasing the equivalent probability and by decreasing the equivalent time.

This paper aims to analyze the performance of Construction Supervision System that contributed to domestic construction projects in public area with respect to reduction of shoddy constructions and improvement of the quality of construction results. Thus research suggested qualitative and quantitative criteria for assessing outcomes and analyzed the performance of Construction Supervision System based on the result of survey questionnaires.

The purpose of the present study was to investigate the development of elementary school student's reasoning strategies used in proportional tasks. Three hundred and ninety elementary students were sampled to investigate their reasoning strategies used in Pouring Water Tasks. Results showed that 4 percentage of students used proportional reasoning strategy. By the way, about 80 % of students used qualitative guess or additive strategies to solve proportion tasks. Further, about fifth-grade or 11-year-old students began to use proportional reasoning strategy. Also, female and malt students' development of reasoning strategies improved from 1st grade across 5th grade and from 6-year-old across 11-year-old. However, female did not show the improvement of strategy development after 5th-grade or 11-year-old. However, male students showed a continuous improvement after the grade or age. In addition, students showed developmental patterns of spurts and plateau, ra thor than a linear developmental pattern. The present study also discussed educational implications of this findings in school curriculum.

Study on users which was done centering information approach, acquisition and interoperability between users and information systems need to be studied in the perspective of information behavior including information acquisition and sharing behavior in the changing information environment. In order to analyze users' information acquisition and sharing behavior's demands, motives and processes in libraries and internet environments, integrated approach of both qualitative and quantitative study were tried by applying Wilson's information behavior concept. Plans for the improvement of information services were suggested on the basis of integrative analysis.

Business of various form such as industry, education, medium is appearing by supply of Internet of all the world. The Information Technology market is developing by leaps and bounds among them, but suitable school information education disgrace and improvement plan were not readied in domestic Information Technology and communication situation. Therefore, this proposal wishes to satisfy purpose by school information education improvement plan and manpower practical conditions about ERP education. So that, is used to accelerate medium and small enterprises information through qualitative, quantitative valuation of medium and small enterprises information manpower supply and demand as well as domestic school information.

Competitiveness strategies has been associated in the tourism literature as a crucial factor for the success of tourist. The study aims to explore the competitiveness strategies for tourism destinations by conducting in-depth interviews with probe questions. Thirteen community enterprises' managers in rural tourism communities were interviewed with a semi-structured interview questionnaire for one or two hours. From the interview data, eight themes in two dimensions were identified as competitiveness strategies of rural community enterprises in rural Korea. Differentiation strategies consist of new product development, service improvement, brand image improvement, advertise and public relation, and concentration. Cost leadership dimension includes cost reduction, increasing benefit, and long-term investment. The findings of this paper implicate the underlying the competitiveness strategies from managers' perspective.
