  • This study discusses a contract to promote collection and recycling of used products in a green supply chain (GSC). A collection incentive contract is combined with a reward-penalty contract. The collection incentive contract for used products is made between a retailer and a manufacturer. The reward-penalty contract for recycling used products is made between a manufacturer and an external institution. A retailer pays an incentive for collecting used products from customers and delivers them to a manufacturer with a product order quantity under uncertainty in product demand. A manufacturer remanufactures products using recyclable parts with acceptable quality levels and covers a part of the retailer's incentive from the recycled parts by sharing the reward from an external institution. Product demand information is assumed as (i) the distribution is known (ii) mean and variance are known. Besides, the optimal decisions for product quantity, collection incentive of used products and lower limit of quality level for recyclable parts under decentralized integrated GSCs. The analysis numerically investigates how (1) contract for recycling activity, (ii) product demand information and (iii) quality of recyclable parts affect the optimal operation for each GSC. Supply chain coordination to shift IGSC is discussed by adopting Nash Bargaining solution.

  • It is truism to say that today's customers demand high quality products and services; nevertheless, nowhere is this more prevalent than in the medical industry. Korea's globalization has increased it's citizen's awareness of greater life expectancies and medical improvements in other regions of the globe. Therefore, it is universally essential that in order to be successful in the medical industry, vendors must meet the ever increasing demands of better educated customers. The purpose of this study was twofold: 1) The first objective was discover what health care services are in demand and the quality factors related to these services. 2) The second objective was to determine a strategy for improving health care service through quality function deployment(QFD). One hundred and ninety-five respondents were randomly selected and asked to fill out a questionnaire after having undergone treatment at a medical clinic, located in Daejon, South Korea. The questionnaire was designed to obtain information about both he clients' satisfaction with, and their sense of the value of the medical treatment they received. Penalty-reward analysis and QFD were used to interpret the survey results and to deploy the collective voices of the customers. The results of the penalty-reward analysis illustrated that the 'communication' service quality factor was classified into an excitement factor that incurs no penalty if not achieved but adds value if the requirement is exceeded. As a result of the QFD analysis on the 'communication' service quality factor, eleven strategic alternatives were prioritized, and isolated a vital service quality characteristic. This characteristic can be implemented to bring value-added changes for the improvement of health care services.

  • In this paper, we study a call admission control algorithm for supporting multicast service under the BcN environment where broadcasting, communication and Internet are converging to be one. It is necessary to control service requests with a certain criteria in order to guarantee QoS because the system capacity is limited. As a possible solution, we divide one multicast service into 3 classes and set up a threshold per each class to control service request. Especially, for the purpose of system benefit, we define system pay-off rate 'GAIN' with the term 'Reward' and 'Penalty' according to admit and reject service request. And we confine the range of threshold which makes GAIN to be maximized. For the performance analysis, we model the system as M/M/m/m queueing system, investigate GAIN under various conditions and show the effectiveness of the proposed algorithm.

  • In this paper, we suggest the Measures to improve the Act Bill for establishing the Game User Committee. The Act Bill has a lot of problems which are violations of criminal legalism due to unclear terms in administrative punishment and violations of The Human Right enjoying freedom of occupation and guaranting property due to not defining provisisons about The Duty of Confidentiality or The Legal Fiction as Public Officials for Purposes of Applying Penalty Provisions. also the duplicate regulations in the Act Bill disrupt game industry development. we have three results that were derived through analysis of Prior studies and precedents. The First is to define details of special reasons in enforcement ordinance and enforcement regulations. The Second is to define The Duty of Confidentiality or The Legal Fiction as Public Officials for Purposes of Applying Penalty Provisions in the act bill. The Third is to address managing the random reward items in the Game Rating and Administration Committee or is to give game user advance notice about the Comntent Dispute Mediation system.

  • Service quality is very important to marketers and consumers in that it has many strategic benefits in contributing to profitability of marketing activities and consumers' problem-solving activities. Moreover, despite the phenomenal growth of physical fitness centers little research has focused on the evaluation of service quality from exercisers' perspectives. The major purpose of this article is to explore the concept of two-factor model and its influences on exerciser's perception of quality. This article attempts to achieve its purpose by (1)classfying critical service attibutes into hygiene factors and satisfiers (2) measuring the relative importance of need criteria (3) evaluating SERVPERF model and SERVQUAL model in service sector and (4)identifying the relationship between overall satisfaction and behavior. In explaining the relationship between perceived performance and overall satisfaction only 27 out of original 33 survey items were appreared to be statistically significant. Hence a penalty-reward analysis was performed on these critical attributes to find out 11 satisfiers and 9 hygiene factors. In addition, it was found that only experience-based norms(SERVPERF model) were more appropriate than expectations to serve as a benchmark against which service experiences were compared(SERVQUAL model). However it must be noted that the degree of association to overall satisfaction was not consistent.

  • INSTRODUCTION Service quality is, unlike goods quality, an abstract and elusive constuct. Service quality and its requirements are not easily understood by consumers, and also present some critical research problems. However, quality is very important to marketers and consumers in that it has many strategic benefits in contributing to profitability of marketing activities and consumers' problem-solving activities. Moreover, despite the phenomenal growth of medical service sector, few researchers have attempted to define and model medical service quality. Especially, little research has focused on the evaluation of medical service quality and patient satisfaction from the perspectives of both the provider and the patient. As competition intensifies and patients are demanding higher quality of medical service, medical service quality and patient satisfaction has emerged as a critical research topic. The major purpose of this article is to explore the concept of medical service quality and its evaluation from both nurse and patient perspectives. This article attempts to achieve its purpose by (1)classfying critical service attibutes into threecategories(satisfiers, hygiene factors, and performance factors). (2)measuring the relative importance of need criteria, (3)evaluating SERVPERF model and SERVQUAL model in medical service sector, and (4)identifying the relationship between perceived quality and overall patient satisfaction. METHOD Data were gathered from a sample of 217 patients and 179 nurses in Seoul-area general hospitals. From the review of previous literature, 50 survey items representing various facets of the medical service quality were developed to form a questionnaire. A five-point scale ranging from "Strongly Agree"(5) to "Strongly Disagree"(1) accompanied each statement(expectation statements, perception statements, and importance statements). To measure overall satisfaction, a seven-point scale was used, ranging from "Very Satisfied"(7) to "Very Dissatisfied"(1) with no verbal labels for scale points 2 through 6 RESULTS In explaining the relationship between perceived performance and overall satisfaction, only 31 variables out of original 50 survey items were proven to be statistically significant. Hence, a penalty-reward analysis was performed on theses 31 critical attributes to find out 17 satisfiers, 8 hygiene factors, and 4 performance factors in patient perspective. The role(category) of each service quality attribute in relation to patient satisfaction was com pared across two groups, that is, patients and nurses. They were little overlapped, suggesting that two groups had different sets of 'perceived quality' attributes. Principal components factor analyses of the patients' and nurses' responses were performed to identify the underlying dimensions for the set of performance(experience) statements. 28 variables were analyzed by using a varimax rotation after deleting three obscure variables. The number of factors to be extracted was determined by evaluating the eigenvalue scores. Six factors wereextracted, accounting for 57.1% of the total variance. Reliability analysis was performed to refine the factors further. Using coefficient alpha, scores of .84 to .65 were obtained. Individual-item analysis indicated that all statements in each of the factors should remain. On 26 attributes of 31 critical service quality attributes, there were gaps between actual patient's importance of need criteria and nurse perceptions of them. Those critical attributes could be classified into four categories based on the relative importance of need criteria and perceived performance from the perspective of patient. This analysis is useful in developing strategic plans for performance improvement. (1) top priorities(high importance and low performance) (in this study)- more health-related information -accuracy in billing - quality of food - appointments at my convenience - information about tests and treatments - prompt service of business office -adequacy of accommodations(elevators, etc) (2) current strengths(high importance and high performance) (3)unnecessary strengths(low importance and high performance) (4) low priorities(low importance and low performance) While 26 service quality attributes of SERPERF model were significantly related to patient satisfation, only 13 attributes of SERVQUAL model were significantly related. This result suggested that only experience-based norms(SERVPERF model) were more appropriate than expectations to serve as a benchmark against which service experiences were compared(SERVQUAL model). However, it must be noted that the degree of association to overall satisfaction was not consistent. There were some gaps between nurse percetions and patient perception of medical service performance. From the patient's viewpoint, "personal likability", "technical skill/trust", and "cares about me" were most significant positioning factors that contributed patient satisfaction. DISCUSSION This study shows that there are inconsistencies between nurse perceptions and patient perceptions of medical service attributes. Also, for service quality improvement, it is most important for nurses to understand what satisfiers, hygiene factors, and performance factors are through two-way communications. Patient satisfaction should be measured, and problems identified should be resolved for survival in intense competitive market conditions. Hence, patient satisfaction monitoring is now becoming a standard marketing tool for healthcare providers and its role is expected to increase.
