The purpose of this study, is to identify the factors affecting reuse intention, determine the accurate demand of suppliers and consumers for qualitative dental care service, and identify the cyclic factors positively affecting one another. The data were analyzed by SPSSWIN 18.0, t-test and one way ANOVA, Pearson correlation and Stepwise multiple regression. Human service quality was significantly positively correlated with service value (r=0.609) and reuse intention (r=0.627) and service value was significantly positively correlated with reuse intention (r=0.645). The higher service value, the higher human service quality, the lower medical service discrimination, the higher level of reuse intention, which accounted for 56.9%. Therefore, it is necessary to make optimal maintenance of the system from the broad viewpoint of dental care in general and apply it in practice by developing good methods steadily.

Cloud storage's elastic expansibility not only provides flexible services for data owners to store their data remotely, but also reduces storage operation and management costs of their data sharing. The data outsourced remotely in the storage space of cloud service provider also brings data security concerns about data integrity. Data integrity verification has become an important technology for detecting the integrity of remote shared data. However, users without data access rights to verify the data integrity will cause unnecessary overhead to data owner and cloud service provider. Especially malicious users who constantly launch data integrity verification will greatly waste service resources. Since data owner is a consumer purchasing cloud services, he needs to bear both the cost of data storage and that of data verification. This paper proposes a verification control algorithm in data integrity verification for remotely outsourced data. It designs an attribute-based encryption verification control algorithm for multiple verifiers. Moreover, data owner and cloud service provider construct a common access structure together and generate a verification sentinel to verify the authority of verifiers according to the access structure. Finally, since cloud service provider cannot know the access structure and the sentry generation operation, it can only authenticate verifiers with satisfying access policy to verify the data integrity for the corresponding outsourced data. Theoretical analysis and experimental results show that the proposed algorithm achieves fine-grained access control to multiple verifiers for the data integrity verification.

This paper is to investigate the relationship between international marketing and service quality, and the moderating effect of gender in that relationship. The data to make an empirical analysis were gathered from 269 workers in telecommunication sector. Multiple regression analysis revealed that (1) education was positively related with tangibility, reliability, responsiveness, empathy, assurance, and (2) internal communication was positively related with tangibility, reliability, responsiveness, assurance, and (3) delegation of authority was positively related with assurance. Hierarchical multiple regression analysis revealed that (4) compensation was more positively related with reliability in woman, and (5) employment security was more positively related with assurance in man.

This paper shows the performance comparisons of several different rate scheduling schemes for non-real time data service over the uplink of burst switching-based direct sequencecode division multiple access (DS/CDMA) system to support the integrated voice/data service. The closed-form solution of optimal scheduling formulation, which minimizes average transmission delay when all of the active data users are transmitting simultaneously, is presented and mathematical analyses with other rate scheduling schemes, which provide efficiency criterion of transmission delay for rate scheduling schemes, are performed. Numerical results show the analyses explicitly.

Ganglioneuroma (GN) is benign neurogenic tumor arising from ganglia of the sympathetic nervous system. They are mostly found at posterior mediastinum, retroperitoneum, and adrenal gland, whereas only 1-5% occurred in the cervical region. GN usually present as a single, painless and slow-growing mass, but multiple cervical occurrences are extremely rare. An 80-year-old woman came to our clinic complained of posterior neck mass for three years. We performed surgical excision, and it was finally diagnosed as GN. We report the unique and rare disease entity with a brief literature review.

The purpose of this study was to investigate the customer service factors and evaluation of consumer satisfaction on the purchase through the C2C E- commerce, focusing on the fashion goods. 190 college students who have purchased products via C2C E-commerce were surveyed. For data analysis, descriptive statistics, 1-test, Pearson＇s correlations, and multiple regression were used. As the results, 50.5% of respondents have purchased fashion products through C2C. Out of 4 C2C characteristics factors. there was statistically the significant difference in only ＇entertainment factor＇ between males and females. All five SERVQUAL＇s factors used for measuring service factors in this study were correlated to customer satisfactions scores. Also. results of multiple regression revealed that assurance, empathy, and reliability were significantly to related to customer satisfaction. Based on these results, fashion marketing strategy for C2C development would be suggested.

Empirical analysis was based on the data of 692 hotel employees from Seoul and Gyung-gi province. To test the relationship between job characteristics and service quality, multiple regression analysis was applied, and hierarchial regression analysis(Cohen & Cohen, 1983) applied to test the moderating effects of gender and tenure. Multiple regressional analysis showed that job importance, job variety, and feedback had an positive impact on tangibility, reliability, responsiveness, assurance, empathy, but autonomy had a negative impact on tangibility, reliability, responsiveness, assurance. Hierarchical regressional analysis showed that gender had moderating effects on 4 relationships between job characteristics and service quality, and tenure had moderating effects on 3 relationships.

This paper developes a multiple-item scale instrument (called SHIPQUAL which is designed to measure the quality of shipping industry. The procedures of developing instrument were followed by recommendations on the developing measures of marketing constructs. We divided shipping service quality into 4 demensions (reliability, conformability, timely/completness, safety) by empirical study. These demensions and scales were varified through the assessment of reliability and validity. Finally, we suggested potential applications of the scale into the shipping industry.

Purpose: The purposes of this study were to provide baseline data for nursing service program and to elevate the quality of service by examining whether nurses' nursing service is related to job stress, job satisfaction, organizational commitment, leadership and nursing service satisfaction in hospitals. Method: Subjects were 135 nurses and 135 patients, working and being in the hospitals in C province & D city from November. 7 to 21, 2005 and completed a structured questionnaire. The data was analyzed using descriptive statistics, t-test, ANOVA, ANCOVA, Pearson's correlation analysis, and multiple regression analysis. Results: The most powerful predictor of nursing service was leadership(60.7%). Altogether leadership, nursing service satisfaction, organizational commitment, and work stress explained 72.5% of nursing service of the nurses in hospitals. Conclusion: The results showed the nurses' nursing service in hospitals was influenced by leadership, nursing service satisfaction, organizational commitment, and job stress. It suggested that concepts of leadership, nursing service satisfaction, organizational commitment, and job stress should be considered in developing nursing services programs.
