This study proposes an integrated approach that uses both a fuzzy service FMEA (failure mode and effect analysis) and HOQ (house of quality) matrix algebra in designing and improving a service system. The fuzzy service FMEA methodology applies the customer satisfaction to the fuzzy RPN model. We fuzzify only the service satisfaction that consist in two failure factors, intangible service and tangible service, to more effectively assess the customer satisfactions on service encounters. Proposed fuzzy service satisfactions with triangle membership function are defuzzified by using the Fuzzy Inference System, and these are eventually identified the ranks on the potential fail points. HOQ matrices are constructed from cause-effect relationships. It is possible for these relationship matrix to find a linear approximation solution on the engineering attributes. Thus, in order to demonstrate how the proposed methods work, practical sample of the A/S part in S Electronic Co. provides for the ranking of the engineering attributes which has been successfully implemented.

Electronic Data Interchange (EDI) between a number of companies goes on increasing on the internet. Although a conventional EDI system reduces business process efforts, time, resources, etc., important information is easily and frequently exposed by well trained hackers and crackers, which inflict a severe loss on the company and even put the company under a crisis. This study integrates the conventional EDI system and Virtual Private Net (VPN) to maximize an overall efficiency of speed and security in data transaction by the level of importance. The EDI system properly interfaced to IPSec and L2TP of VPN allows us to select two modes: the one focuses on a high speed with a low or a medium level security or the other does on a high level security with a low or a medium level speed. Both the company and the end users get a lot of tangible and intangible advantages by integrating the EDI system and VPN.

In 1995, 100PPM Quality Certification System(QCS) has been established by the Industrial Advancement Administration. This study shows the tangible and intangible effects of 100PPM QCS in Korea. 100PPM QCS has been introduced to observe the substantial objects and to solve problems. To achieve this goal, problems of certification system were classified by certification inspection items, certification inspection, post management and inspection methods. This set of problems are also found when enterprise carrying out 100PPM. It is suggested to utilize the proposed problems and improvements which are to upgrade and correct the 100PPM QCS in the beginning stage.

The ANP(Analytic Network Process), though based on the AHP(Analytic Hierarchy Process), is a system for the analysis, synthesis, and justification of complex decisions with the capability to model non-linear relations between the elements. ANP allows the decision makers to leap beyond the traditional hierarchy to the interdependent environment of network modeling. The ANP is designed for problems characterized by the added complexity of interdependencies such as feedback and dependencies among problem elements. Using a network approach makes it possible to represent and analyze interactions, incorporate non-linear relations between the elements, and synthesize mutual effects by a single logical procedure. This study intends to evaluate the contribution of technology in intangible assets by the AHP and ANP.

Purpose : The purpose of the study were to describe outcomes of CHP activities, and to evaluate the economic validity of CHP through a cost-benefit analysis. Method : The sample size was 272. Data were collected using a researcher developed questionnaire from November 1999 to March, 2000. Result : The mean age of CHPs was 39.6 (SD-36). In regard to marital status, 90.8% of the respondents were married. 72% of the CHPs had associate degree. Among CHP activities, providing medical services was 50%, followed by home care visits 20% and health promotion services 20%, preventive services 10%. Total costs per month incurred to CHP activities was \3,053,437($2,442.7). Total benefits per month was \6,711,525($5,369.2). Hence, net benefit was calculated as \3,658,089($2,926). Conclusion : Cost-benefit ratio was 2.20, which provides the evidence of the economic viability of CHP program. The result of cost-benefit analysis, however, would more strongly support the economic value of CHP if intangible benefits of CHP activities such as decreases in pain and suffering and increased quality of life, could be counted.

This paper discusses a scheduling problem on object-oriented developments over multiple teams with limited resources in matrix organization. The objective of the problem is to minimize the makespan of overall projects. There are tangible and intangible advantages such as efficient resource share, improvement of productivity, development efforts and cost reduction, etc. by dispatching resources properly to the development teams. Traditionally, the project scheduling has been done with a manager's intuition or heuristic. We present a scheduling model with illustrative examples, stochastic search approach, and apply a variety of problems generated randomly to the approach. The results are analysed.

Even though Islamic microfinance has flourished in the last two decades, still it faces some problems related to its sustainability and outreach. Market orientation has generally developed some strategies for organizations aiming to retain the current customers and attract new ones. In addition, organizations, which are addressed as Islamic, should be Shariah-compliant in all aspects. This paper introduces the market orientation concept which is adapted to Shariah rules and recommends a solution for sustainability problems of Islamic microfinance institutions. Current study tries to provide some intangible instances and evidences to introduce and use Islamic market orientation concept for Islamic microfinance institutions, in particular.

This paper proposes performance measurement method of quality small-group activity in business. This paper collects and analyzes quality circle activities data respect to tangible and intangible effect in national quality circles competitions festival. This paper proposes QPI (quality-circle performance index) based on Balanced Scorecard for quality small-group activity in quality improvement area. QPI is to measure the performance of quality improvement activities in the business firms. QPI is able to use widely in industries to provide a performance measure of quality small-group activity. In this paper, we propose the application method of QPl.

This study aims to explore the difficulties of evidence-based pharmaceutical policy-making in the Korean context where several pharmaceutical policies were introduced within a short period. Semi-structured in-depth interviews were performed with eight experts in the Korean pharmaceutical arena. The key challenge in Korean situation might be the apparent lack of available evidence caused by the limited resources, the lack of policy consistency and coordination ability in the authorities and distrust across stakeholders. To build an evidence-based tradition, it is essential to resolve the tangible lack. At once, more fundamental changes seem to be required in the intangible policy environments.
