The real estate management includes not only the brokerage, property management, development, investment and consulting which are related to real estate handling, but also the human resources who deal with the real estate business. The level of management quality of Korean real estate business is rather poor. This paper deals with management innovation of real estate management using Six Sigma methodology The main focus of this Paper is to develop strategy Planning, and is to select critical success factors for each strategy to make an advanced management system for real estate business. This paper is a case study, and the target company for this innovation is ERA-Korea Company. Seven strategies are proposed, and for each strategy several critical success factors are suggested. Through this case study, the authors hope that a management quality model for real estate business is proposed, and an improved management method can be adopted in the other real estate companies.

The purpose of this study was to determine the service quality satisfier and dissatisfier factors of family restaurants in Korea by using a qualitative research method, the critical incident technique(CIT). The CIT helps researchers find new factors or attributes by grouping key issues and categorizing common factors from the raw data, critical incidents which critically satisfied or dissatisfied customers. The respondents must describe the incidents in details. There are many previous studies on the attributes related to service qualities, selections, and revisiting intentions and the relationships between the attributes. These studies offer many insights for general trends and directions for managing service qualities, but not how to improve service quality practically. It is difficult to know specific service quality factors especially influencing Korean customers because the factors come from previous research and not from the respondents themselves. Therefore, this research categorized key satisfier and dissatisfier factors from 402 critical incidents described by 261 respondents into 5 groups and 33 subcategories. Real cases and examples are also explained that either critically satisfied for dissatisfied customers at family restaurants.

In this manuscript, a modified single sampling plan is proposed for the inspection of products in which the nonconforming items can be classified in to two categories namely critical and non-critical; and explained with the help of industrial example. The operating procedure of this plan is also proposed and the performance measures such as the probability of acceptance, average sample number, average total inspection and average out going quality are also derived. The optimal parameters are determined which will have minimum sample size. The efficiency of the proposed plan is also discussed over the conventional single sampling plan. The extensive tables for selecting a modified single sampling plan based on AQL and LQL are provided for both Binomial and Poisson distributions and explained with the help of industrial data.

An experimental study on critical heat flux (CHF) has been performed in an internally heated vertical annulus with non-uniform heating. The CHF data for the chopped cosine heat flux have been compared with those for uniform heat flux obtained from the previous study of the authors, in order to investigate the effect of axial heat flux distribution on CHF. The local CHF with the parameters such as mass flux and critical quality shows an irregular behavior. However, the total critical power with mass flux and the average CHF with critical quality are represented by a unique curve without the irregularity. The effect of the heat flux distribution on CHF is large at low pressure conditions but becomes rapidly smaller as the pressure increases. The relationship between the critical quality and the boiling length is represented by a single curve, independent of the axial heat flux distribution. For non-uniform axial heat flux distribution, the prediction results from Doerffer et al.'s and Bowling's CHF correlations have considerably large errors, compared to the prediction for uniform heat flux distribution.

Quality Assurance Principles must be effectively implemented in developments and in use of safety critical software in nuclear industry. Brief definitions related to computer software and quality assurance were defined and several methods for evaluating software quality were proposed herewith. Independent verification and validation was suggested to assure the quality of safety critical software.

The current health care system demands provisions for patient care in perspectives of a cost-effectiveness and patient satisfaction. Critical pathway implementation facilitates optimal sequencing and intervention timing of patient care, and makes medical team and patients participate in a treatment actively. In this study, a critical pathway was developed and implemented to patients with osmidrosis who undertake operation. Sixty patients were included in the study. The critical pathway was implemented for care of 26 patients while the traditional care was implemented for 34 patients. In the critical pathway implemented group, time needed for charting and unessential working was reduced. Mean time amount of time for patient nursing was increased. The critical pathway implementation is an effective method to utilize time of medical team. Also it increases the satisfaction index of patients and medical team simultaneously.

The objective of this study is to identify the critical dimensions of comprehensive quality and to prioritize them for improvement of the quality competitive advantage. The critical dimensions, sub-dimensions and measurement items of comprehensive quality were abstracted from literature of quality, and constructed a model of hierarchical structure. 115 experts in four groups(supplier, buyer, consultant, and professor) were participated in pair-wise comparison of quality dimensions, but some of these responses were removed because the overall consistency of evaluator judgements exceed the acceptable ratio of 0.10. The priorities of quality dimensions for industrial and consumption goods were calculated respectively using the analytic hierarchy process(AHP) approach. As a result, product quality had the highest weight of 0.65, followed by support quality(0.18) and service quality(0.17) for industrial goods while product quality also had the highest weight of 0.62, but service quality(0.22) was preferred over support quality(0.16) for consumption goods.
