The purposes of this study were to a) measure the service quality attributes of foodservice type such as school foodservice, hospital foodservice and business & industry(B&I) foodservice, managed by contract management company(CMC), b) compare with service quality attributes by CMC scale, c) analyze overall customer satisfaction(CS) by the foodservice type and the CMC scale, and d) identify the effect of service quality attributes on an overall CS by the foodservice type and the CMC scale. The questionnaires were handed out to 6,620 customers of 207 school, 38 hospital, and 86 B&I foodservices in 108 CMCs. The statistical data analysis was completed using SPSS Win(ver 12.0) for descriptive analysis, t-test, reliability analysis, and multiple linear regression analysis. From an analysis on service quality attributes, 'proper arrangement of table and chair at hall distribution(3.53)', 'operation of nutrition education(3.50)' were highly perceived to student, 'correctable serving(4.08)', 'serve at fixed distribution time(4.08)', 'kindness of serving employee(4.04)' were highly perceived to patient, 'employee's kindness(3.84)' were highly perceived to customer of B&I. In comparison of service quality attributes by CMC scale, most scores of large enterprise(LE) were significantly higher than small and medium sized enterprise(SME) in school foodservice, hospital foodservice and B&I foodservice. Overall CS levels were 3.53 out of a maximum 5 on B&I, 3.46 on school, and 3.44 on hospital and were evaluated differently CS score by CMC scale. Finally, regression results for the effects of service quality attributes on overall CS by each of foodservice type were identified significantly different service quality attributes by foodservice type such as school, hospital, B&I(p<.001) and by CMC scale. For considering the goal of enterprise on profit-making through CS and the needs of customer on CS at moment of truth(MOT), the findings should be applied to the CMC and the foodservice industry.

The epidermal structure and stomatal types in vegetative and reproductive organs of three species of Bryophyllum(B. crenatum, B. diagremontion, B. tubiflorum) were described. The epidermal cells were polygonal, isodiametric, and rectangular in the leaves and stems, and elongated cells in the stamens, styles, and ovaries. These cells were commonly thick, and arched or sinuous in the leaves, epiphylous bunds, petals and ovaries. They were straight in the stems, petioles, pedicels, and peduncles. In both vegetative and reproductive organs, the subsidiary cell walls were commonly thin and mostly arched in all the organs. The great majority of the mature stomata in all the organs were helicocytic type with a helix of four to six subsidiary cells. The mature stomata varied from organ to organ with regard to the number and arangement of subsidiary cells. The ontogenetic type of stomata in all the organs was mostly helico-eumesogenous type. This type was subdivided into three subtypes such as parahelico-eumesogenous, anomohelico-eumesogenous, and diahelico-eumesogenous stomata on the basis of the division angle fo the guard mother cell. Sometimes, the anisoeumesogenous type was found in various organs. This type was subdivided into three subtypes such as paraniso-eumesogenous, anomoaniso-eumesogenous, and dianisoeummesogenous stomata. The tetra-eumesogenous and duplotetra-eumesogenous types were rarely found; the former in the leaf of B. crenatum and the latter in the leaf of B. diagremontiana. Anomometric patterns in the mesogenous categorry of stomatal types was observed in a few organs of all the materials. A new stomatal type with tetra-eumesogenous stoma within a girdle of three subsidiary cells fo aniso-eumesogenous in the leaf of B. diagremontiana was firstly observed in the vascular plants. This stoma was termed the cotetra-aniso-eumesogenous type. Anormal stomata such as aborted stomata, single guard cells, stoma with a constricted part in the middle of large guard cells, and arrested stomata were found in the various organs of all the materials.

Purpose : Enteroviruses are the most common cause of aseptic meningitis. The epidemics of aseptic meningitis in 1993 and 1996 were mostly caused by echovirus type 9. Identification of the causative virus of aseptic meningitis in epidemics, is very important not only for diagnosis but also for epidemiologic purpose. The purpose of this study was to identify the causative virus and investigate the relationship between aseptic meningitis, prevailed in Masan and surrounding areas in Kyoungsangnamdo in 1997, and its clinical manifestations. Methods : One hundred twenty eight cerebrospinal fluid(CSF) and 239 stool specimens were obtained from 239 patients(213 children and 26 adult patients) with aseptic meningitis were admitted to Masan Fatima Hospitals from March to October 1997. Viral isolation and serotype identification was performed by cell culture and immunofluorescent test. Enteroviruses not typed by immunofluorescent test was confirmed by reverse transcription-polymerase chain reaction(RT-PCR). Results : 1) The peak incidence was noted in June. 2) The age of 239 patients(pediatrics-213 cases, internal medicine-26 cases) that were diagnosed ranged from neonate to 35 years, the age of the patients of pediatrics ranged from neonate to 15years(mean 4.9 years), the age of the patients of internal medicine (above 16 years) ranged from 16 years to 35 years(mean 24.2 years). 3) Fifty-three(41.4%) of 128 CSF specimens were positive for enteroviruses, and 163(68.2%) of 239 stool specimens were positive for enteroviruses respectively. 4) Serotypes of 53 enteroviruses isolated from CSF were 16(30.2%) of echovirus type 30, 6(11.3%) of echovirus type 6, 1 of echovirus type 4, 4 of untyped echovirus, 1 of coxsackievirus type B5, and 24 isolates of untyped enteroviruses. Of 163 enterovirus isolated from stool were 72(44.2%) of echovirus type 30, 21(12.9%) of echovirus type 6, 1 of echovirus type 4, 17(10.4%) of undetermined subtyped echovirus, 1 of coxsackievirus type B5, 2 of A24, 3 of undetermined subtyped coxsackievirus type B, and 46 isolates of untyped enterovirus. Conclusion : There were epidemics of aseptic meningitis in the central areas of Kyoungsangnamdo from March to October 1997. The main causative organism was thought to be the echovirus type 30, and echovirus type 4, 6, coxsackievirus B5 and A24 were also thought to contribute to the epidemics.

Background: Costimulation is a critical process in Ag-specific immune responses. Both B7.1 and CD28 molecules have been reported to stimulate T cell responses during antigen presentation. Therefore, we tested whether Ag-specific immune responses as well as protective immunity are influenced by coinjecting with B7.1 and CD28 cDNAs in a mouse HSV-2 challenge model system. Methods: ELISA was used to detect levels of antibodies, cytokines and chemokines while thymidine incorporation assay was used to evaluate T cell proliferation levels. Results: Ag-specific antibody responses were enhanced by CD28 coinjection but not by B7.1 coinjection. Furthermore, CD28 coinjection increased IgG1 production to a significant level, as compared to pgD+pcDNA3, suggesting that CD28 drives Th2 type responses. In contrast, B7.1 coinjection showed the opposite, suggesting a Th1 bias. B7.1 coinjection also enhanced Ag-specific Th cell proliferative responses as well as production of Th1 type cytokines and chemokines significantly higher than pgD+pcDNA3. However, CD28 coinjection decreased Ag-specific Th cell proliferative responses as well as production of Th1 types of cytokines and chemokine significantly lower than pgD+pcDNA3. Only MCP-1 production was enhanced by CD28. B7.1 coimmunized animals exhibited an enhanced survival rate as well as decreased herpetic lesion formation, as compared to pgD+pcDNA3. In contrast, CD28 vaccinated animals exhibited decreased survival from lethal challenge. Conclusion: This study shows that B7.1 enhances protective Th1 type cellular immunity against HSV-2 challenge while CD28 drives a more detrimental Th2 type immunity against HSV-2 challenge, supporting an opposite role of B7.1 and CD28 in Ag-specific immune responses to a Th1 vs Th2 type.

The purpose of this study is to analyze how the task group functioning and need styles have influence on role conflict and role ambiguity as the employee's personality engaged in the service industry such as a hotel. This study uses the hierarchical regression analysis method. Data were collected by the survey method from employees engaged in the service industry such as a hotel located Seoul, the Province of Gyeonggi, and the Province of Gangwon. The study result shows that to the employees in the type A and type X styles, the task group functioning and need styles are not significantly related to the role conflict. But to the employees in the type B style, the task group functioning and need styles are significantly related to the role conflict. And the result shows that to the employees in the type B style, the lower the faith in peers and management, the more the role conflict occur. On the other hand, the study result shows that to the employees in the type A styles, the task group functioning is significantly related to the role ambiguity. And to the employees in the type B style, the higher the faith in peers and management, the more the role ambiguity occur. On the contrary, to the employees in the type X style, need styles are significantly related to the role ambiguity. But to the employees in the type X style, the higher the need for achievement, the more the role ambiguity occur. On the other hand, the study result shows that to the employees in the type B styles, the task group functioning and need styles are significantly related to the role ambiguity. And to the employees in the type B style, the higher the need for achievement, the more the role ambiguity occur or the lower the confidence in peers and management, the more the role ambiguity occur. Although this study provides several managerial implications, this study has some limitations. Specifically data were collected from only the hotel industry in Seoul, the Province of Gyeonggi, and the Province of Gangwon. In spite of the limitations, the study results could be used valuably in case of the personnel managers which manage the employees under the conflict situations.

In this paper, the concept of a weighted b_ν(α)-metric space is introduced as a generalization of the b_ν(s)-metric space and ν-metric space. We prove some fixed point results of the Reich-type contraction in the weighted b_ν(α)-metric space. Furthermore, we generalize Reich's theorem by extending the result to a weighted b_ν(α)-metric space.
