The objectives of this study were to develop theoretical model that outlined the antecedents of satisfaction in an industrial buying context, to investigate product usage level as an outcome of the two economic factors, and to examine the relationships of product, usage level and service factor with customer satisfaction as the organizational market for hospitality is growing. To figure out the relevant constructs and variables for this study, related literature was reviewed. Then, to satisfy the purposes of the study, structural equation modeling method was utilized with a confirmatory factor analysis. A confirmatory factor analysis examined a four-factor solution developed from the factor analysis. Also, goodness-of-fits for measurement model and structural model were evaluated to test the reliability of both models. The various measures of overall model goodness-of-fit lend acceptable level of support to deeming the results an acceptable representation of the hypothesized constructs. Based on the acceptable level of support for the goodness-of-fit tests, the relationships among the constructs in the model were examined. Finally, two alternative models were proposed and compared to the original model.

This paper introduces trust measurement that is composed of trust variables and fuzzy cognitive map. The improved trust measuring method using a stratified FCM can be used to measure the level of risk involved in a specific auction transaction concerned. To reduce the auction transaction cost and time, the proposed system recommends a differentiated transaction protocol according to the risk based on trust measurement. In this system, trust measurement can also be applied for differentiated and varied auction services.

A control scheme to select the appropriate layer between macro- and microcell hierarchical structure is considered. With the assumption that the each mobile speed is known to the system. the algorithm determines the optimal velocity threshold by which the cell section performed. The optimal criterion is to minimize the Grade of Service(GOS), a service criterion in cellular telephone systems. Mobile station with faster speed relative to the determined optimal speed threshold are assigned to a macrocell, while slower moving terminals are assigned to the smaller cells, i,e.. microcells. For the evaluation purpose for the proposed scheme, two different evaluation perspectives are compared and the algorithm proves to work

The present study evaluated the effects of various agents on magnesium sulfate (Mg^(2+))-induced relaxation in aorta and blood pressure lowering in anesthetized guinea pigs. Mg^(2+) inhibited phenylephrine (PE)- or 40 mM KC1-induced sustained contraction of endothelium-intact (+E) guinea pig aortic rings in concentration-dependent manner. In preparations preconstricted with PE or KC1, Mg^(2+)-induced concentration-dependent relaxations. In preparations preconstricted with PE or KCl, Mg^(2+)-induced relaxations were not affected by the removal of endothelium (-E) and by the pretreatment of aortic rings with NO synthase (NOS) inhibitors (L-NAME and LNNA), guanylate cyclase inhibitors (methylene blue and ODQ, adenylate cyclase inhibitor (MDL), K^(+) channel blockers (glibenclamide and tetrabutylammonium), nifedipine or ryanodine. However, Mg^(2+)-induced relaxations were inhibited by Na^(+)-Mg^(2+) exchange inhibitor (imipramine) or removal (or attenuation) of extracellular Ca^(2+) in +E aortic rings. PE-induced contraction was not inhibited by nifedipine. In addition, Mg^(2+)-induced relaxations were inhibited by phospholipase C inhibitor (NCDC) or inositol monophosphatase inhibitor (lithium), but not by protein kinase C inhibitor (staurosporine). In vi패 infusion of Mg^(2+), directly into the femoral veins of guinea pigs, elicited sustained decrease in arterial blood pressure. The Mg^(2+)-lowered blood pressure was attenuated by intravenous administration of imipramine or lithium, but not by methylene blue, indomethacin, tetrabutylammonium nifedipine, LNNA, L-NAME or saponin (as an endothelium removal agent). These results suggest that endothelium independent vasorelaxant effect of Mg^(2+) on aortic ring appear to play important roles on the antihypertensive action in guinea pig, most likely via the inhibitory action of Mg^(2+) on the intracellular C^(2+) involve in PLC-IP pathway and influx (through the Na^(+)-Mg^(2+) exchanger) into the cell in guinea pig aorta.

One hundred and fourteen patients with surgical infection were studied. 65 patients of these had intraabdominal abscess, and the remainders had wound infection. The patients surveyed were admitted at the department of general surgery in Chungnam National University Hospital during the period from April 1981 to March 1984. The author has analyzed clinically the cases with respects of age, sex, primary diseases and has investigated the causative agents of surgical infection, and also studied drug resistance of isolated strains to the various antibiotics by antibiotic susceptibility test. The results were summarized as follows: 1. In the distribution of age, the fifties and sixties (48.2%) were two times as many as the thirties and forties (28.1%). The prevalence rates were 43.0% in summer and 14.9% in winter. 2. The commonest primary disease in intraabdominal abscess and wound infection was perforated appendicitis and periappendiceal abscess (36.9% and 35.7%, respectively). 3. Positive culture were obtained in 84.2% of 114 patients. Of these, intraabdominal abscess was 89.2% and wound infection was 77.6%. Aerobes isolated were 63.5%, aerobes and anaerobes isolated concomitantly were 29.2%, and anaerobes isolated were 7. 3%. 4. Total 193 strains were isolated from patients with surgical infection. Of these, aerobes were 72.6% and anaerobes were 27.4%. The commonest organism was Escherichia coli as 36.9%, the next was Bacteroides as 18.5%, the others isolated were Klebsiella as 11.3%, and Proteus as 10.1%, etc. 5. E. coli was 48.1% of isolated aerobes and Bacteroides fragilis was 50.0% of isolated anaerobes 6. Isolated strains of E. coli and Bacteroides fragilis from patients with surgical infection were resistant to the most of antibiotics such as erythromycin, kanamycin, lincomycin, neomycin, penicillin and tetracycline, but sensitive to chloramphenicol and cephalothin. As above results, E. coli and Bacteroides fragilis were most commonly isolated from patients with surgical infection of the abdomen, and most of isolated strains were resistant to various antibiotics. Therefore, the treatment of surgical infection requires not only proper surgical managements but also appropriate antibacterial therapy by the results of antibiotic susceptibility test.

Purpose : This is to review the cases of posterior maxillary segmental osteotomies to regain the interarch spaces for dental implants in the posterior mandible. Materials & Methods: Seven patients who presented with alveolar extrusion of upper posterior molars underwent segmental osteotomies by single-stage Kufner's buccal approach under the intravenous sedation and local anesthesia. The posterior maxillary cento-alveolar segments were repositioned upward using pre-fabricated palato-occlusal resin splints and immobilized with osteosynthesis microplates and screws Dental implants were installated simultaneously. The regained spaces, tooth vitality, periodontal healing, relapse, tenderness on function, and complications including maxillary sinus involvements were evaluated periodically for over one year after the surgeries. Results : The single-tage procedures were completed within 80 minutes without any surgical complications. The posterior maxillary segments were repositioned upward to regain the interarch spaces ranging from 2.5 to 5.5mm. All teeth involved in the procedures keep their vitalities. The repositioned segments were maintained showing neither evidence of periodontal break-down nor tenderness to function, One patient whose segments had not been immobilized by osteosynthesis plate resulted in 2mm down-ward relapse in post-operative 8 months. A case of postoperative nasal bleeding from the posterior-lateral wall resulted in oroantral fistula and chronic maxillary sinusitis later. Conclusion : The extruded dento-alveolar segments of the posterior maxilla were repositioned properly by Kufner's one-stage segmental osteotomies. One microplate can be of help to keep the position until the osseous healing enough to support the masticatory force.
