Purpose: The purpose of this paper proposes an effective and systematic methods of risk management in product development project. Methods: This paper first discusses what risk factors be considered during product development period and then presented a model for preventive risk management. For that, this paper proposes how to evaluate the risk factors and risk events, and how to select prevention action for managing risk factors effectively. For this process, this paper uses well-known quality tools such as House of Quality (HOQ) and Failure Mode and Effects Criticality Analysis (FMECA) methods. Results: There is an inherent need for the development of robust risk management framework in order for product development projects to be successful. The identification and quantification of risk factors, risk events, and prevention actions can have significant effects on the success of a product development projects. Project managers can implement the proposed model to improve project success. Conclusion: The findings showed that this method would be effective for project managements in dealing with risk management issues in product development projects.

In order to solve water quality problem of domestic dam reservoir, many projects have been performed in a point of view to restoration of water quality. This study was carried out to evaluate the effect of release from sediment on water quality and release characteristics. Daecheong dam reservoir was investigated for two years, from 1998 to 1999. The nutrient release rates of Daecheong reservoir is less than foreign eutrophic reservoir at anoxic condition. For the evaluation of the effect of nutrient release on water quality, internal and external loading was calculated at Daecheong reservoir. As total phosphorus loading from sediment is calculated 9.3 ton/yr and inflow loading from Daecheong reservoir watershed 118 ton/yr, internal loading shows the portion of 7.88% to external loading. At this study, because sampling point was choosed at the point where much sediment is accumulated, experimental result is more than average release rates. Because Daecheong reservoir shows complete thermal stratification and anoxic condition below 30m from water surface in summer seasons, released phosphorus from sediment can not transfer to epilimnion and eventually resettles. Therefore sediment has insignificant impacts on water quality on Daecheong dam reservoir.

Purpose: This study was conducted to investigate the worker's service quality of the elders at a nursing home. Methods: A total of 371 workers, who were engaged in caring for the elders at a nursing home in B-Metropolitan city and Kyungnam, answered the questionnaires regarding the knowledge & skills of service, information cognition and service quality for the elders related to their clients. Results: Service quality for the elders was significantly correlated to the level of knowledge and skills, as well as the information cognition for the elders, and frequency of educational participation. Service quality for the elders was statistically significant predictors of knowledge and skills, and information cognition for the elders. These two variables accounted for 37% of the variance in service quality for the elders. Conclusion: In order to improve the worker's care level, the workers engaged in caring for the elders should make the efforts to be given a nursing education related to the knowledge & skills, as well as the information for the elders.

In this study, the effects of physical parameters (30-270 MPa of pressure, 3-57 min of time, and 1-$49^{\circ}C$ of temperature) on pork quality were investigated. Response surface methodology was used in order to monitor and model the changes in pork quality under varied pressure conditions. As quality characteristics, shear force, water holding capacity (WHC) and the CIE color of pork were measured, and optimum pressure conditions were evaluated by statistical modeling. Pressure improved the WHC of pork at relatively low temperature ($<25^{\circ}C$); however, the opposite occurred with increasing temperature. Although pressure and temperature affected the tenderness of the meat, interaction effects among variations were not observed. At pressure levels higher than 200 MPa, the color of pork differed markedly from that of the untreated controls. In particular, differential scanning calorimetry (DSC) revealed marked evidence of myosin denaturation. The present study demonstrates that pork quality varies depending on pressure conditions.

This is an empirical study on Korean traditional restaurant service providers and customers who get direct service from them. This study focuses on the service performance determiners; customer satisfaction, service quality, service providers' satisfaction and loyalty. In order to meet its purpose, we survey 1,000 customers who have visited Korean traditional restaurants. This survey uses the SERVPERF service quality measuring theory. The results are as follows: First, the service providers' satisfaction have an effect on service quality, so the supervisor of a Korean traditional restaurant should construct a HRM (Human Resources Management) system for increasing employees' satisfaction. Second, employees' loyalty is significant, but its effect is lower than their satisfaction. Third, service quality affects customers' satisfaction and loyalty significantly. Fourth, employees' satisfaction and loyalty considerably influences customers' satisfaction and loyalty. Consequently, restaurant managers put their effort into increasing employees' satisfaction, loyalty, and service quality.

Nowadays, lots of software that have similar functions is being produced. Hence it is getting more important to select the best and suitable software for each individual or company. Moreover, there are few trustworthy materials regarding to the objective procedure and criteria for the best evaluation of the software quality. To overcome these problems, benchmarking has been carried out. However, benchmarking is also confronting the limit of quality evaluation verification due to the difficult of the objectification of the major test items. To solve these problems, some others try to evaluate the quality of software using objective criteria of evaluation based on ISO/IEC standards. Nevertheless, this method using these defined evaluation items and criteria may result in not very reliable outcome. Therefore, this paper offers the evaluation items reflected in the characteristics of each software in order to prove the validity of the proposed method. Moreover, the objective and quantitative criterion which analyzes and reflects the organization characteristics using AHP methodology is applied to the experiment and performance evaluation. Hence we expect that the proposed method provides the needs of the re-establishment of software quality evaluation criteria and the improvement of process in terms of management.

Purpose: This study aimed to identify the perception of quality-certified children's preferred foods as well as consumption behaviors of nursery directors and parents. Methods: A total of 243 nursery directors and parents of preschool children were surveyed using questionnaires. Results: Parents' perception scores were lower than directors' scores for many of the questions. Parents showed significantly higher scores for food safety standard questions and nutritional fortifying questions than directors (p<0.001 each). On the other hand, directors showed significantly higher scores for questions about products nutrition and safety (p<0.001, p<0.01). When buying children's favorite food items, food additives and hygiene level of vendors were the most important, in that order. Parents' scores for questions on purchasing behaviors of quality-certified children's preferred foods were significantly higher than those of directors'. Further, respondents with nutritional education experience showed high behavior scores. Conclusion: It can be concluded that promotion of quality-certified children's preferred foods is insufficient. The nutrition education group showed high scores for perception and positive consumption behaviors of quality-certified children's preferred foods. It is important to cooperate with nursery directors and parents of preschoolers to further children's nutritional education.

Global competitive pressures are asking industrial companies to find the best way to meet their customer's requirements, reduce the costs of products, and increase productivity. Quality improvement has been proposed and implemented as a primary means of achieving these purposes. The quality improvement usually includes a goal of reducing the costs due to poor quality. While these costs of poor quality (COPQ) are not known precisely, they are known to be very high. Also, they may be underestimated by the hidden costs due to non-value activities, such as potential lost sales, costs of redesign due to quality reasons, and extra manufacturing costs due to defects, etc. In any manufacturing or service operation, all actions and resource expenditures of a company should be focused on creating value for customers. Any activity or resource of not creating the value for customers could be regarded as waste, which consequently causes the COPQ. Some companies did use dashboards to understand and identify value added or non-value added activities in order to reduce or eliminate wastes. These dashboards must be properly designed to consider inherent differences in manufacturing or service operations among business organizations. In addition, a structured quality improvement program such as the Six Sigma must support these dashboards. In this paper, a case study of designing dashboards for evaluating and reporting the COPQ in business units is presented.
