PURPOSE: This study was to explore health experiences of the low-income elderly living alone reflected in Newman's Health as expanding consciousness theory. METHOD: The researcher used Newman's praxis methodology because it is good for showing the process of interaction between the researcher and the low-income elderly living alone. RESULTS: The significant characteristics of early health experience during a participant's lifetime were demonstrated that blamed themselves, being burden of themselves hopeless of their lives. However, after a turning point in health experience. The health experience of most of the participants evolved as expanding consciousness. CONCLUSION: This study has provided support for Newman's theory of health. Most of the participants recognized meanings in their patterns and authentic caring relationships with the nurse as researcher, pattern recognition as a nursing practice was a meaningful transforming process in the participant-nurse partnership. This participatory approach expands the scope of sharing health experience with the elderly living alone and with caring community people.

The Schatzki ring, a submucosal fibrotic thickening of the lower esophagus, occurs at the squamocolumnar junction and is invariably associated with an esophageal histal hernia The ring is discrete narrowing covered with squamous epithelium on its superior aspect and columnar epithelium on its inferior aspect, with various degrees of submucosal fibrosis supporting the annulair ring. Symptoms, when present, are generally those of distal esophageal obstruction to the passage of solids and highly associated with ring diameter. The pathogenesis and etlology are obscure. But one theory suggests that they are caused by gastroesophageal reflux. The vast maiority of symptomatic Schatzki rings sre ameneble to dilation, a few patients will require surgical antireflux measures after dilatation. We have experienced a case of Schatzki ring associated with reflux esophagitis and esophageal hiatal hernia by the esophagogram after barium swallowing and endoscopy. So we report this case with brief review of the previous literatures.

STATEMENT OF PROBLEM: Since the concept of osseointegration in dental implants was introduced by Branemark et al, high long-term success rates have been achieved. Though the use of dental implants have increased dramatically, there are few studies on domestic implants with clinical and objective long-term data. PURPOSE: The aim of this retrospective study was to provide long-term data on the Neoplant(R) implant, which features a sandblasted and acid-etched surface and external connection. MATERIAL AND METHODS: 96 Neoplant(R) implants placed in 25 patients in Yonsei University Hospital were examined to determine the effect of the factors on marginal bone loss, through clinical and radiographic results during 18 to 57 month period. Results: 1. Out of a total of 96 implants placed in 25 patients, two fixtures were lost, resulting in 97.9% of cumulative survival rate. 2. Throughout the study period, the survival rates were 96.8% in the maxilla and 98.5% in the mandible. The survival rates were 97.6% in the posterior regions and 100% in the anterior regions. 3. The mean bone loss for the first year after prosthesis placement and the mean annual bone loss after the first year for men were significantly higher than that of women (P<0.05). 4. The group of partial edentulism with no posterior teeth distal to the implant prosthesis showed significantly more bone loss compared to the group of partial edentulism with presence of posterior teeth distal to the implant prosthesis in terms of mean bone loss for the first year and after the first year (P<0.05). 5. The mean annual bone loss after the first year was more pronounced in posterior regions compared to anterior regions (P<0.05). 6. No significant difference in marginal bone loss was found in the following factors: jaws, type of prostheses, type of opposing dentition, and submerged /non-submerged implants (P<0.05). CONCLUSION: On the basis of these results, the factors influencing marginal bone loss were gender, type of edentulism, and location in the arch, while the factors such as arch, type of prostheses, type of opposing dentition, submerged / non- submerged implants had no significant effect on bone loss. In the present study, the cumulative survival rate of the Neoplant(R) implant with a sandblasted and acid-etched surface was 97.9% up to a maximum 57-month period. Further long-term investigations for this type of implant system and evaluation of other various domestic implant systems are needed in future studies.

STATEMENT OF PROBLEM: Volume stability, microstructure reproducibility and fluidity along with compatibility with dental stone must be in consideration in order to use tissue conditioner as a material for functional impression. There are few studies concerning the influence of time factor in oral condition on surface roughness of the stone and optimal retention period in the oral cavity considering such changes in surface roughness. PURPOSE: The purpose of this study was to find out the influence of various kinds of tissue conditioner, its powder/liquid ratio and immersion time on surface roughness of the stone. MATERIAL AND METHODS: Materials used in this study were the three kinds of tissue conditioners (Coe-Comfort, Visco-Gel, Soft-Liner) and were grouped into three: group R - mixed with standard powder/liquid ratio that was recommended by the manufacturers, group M - mixed with 20% more powder, group L - mixed with 20% less powder. Specimens were made with the size of 20 mm diameter and 2 mm width. Each tissue conditioner specimens were subdivided into 5 groups according to the immersion time (0 hour, 1 day, 3 days, 5 days, 7 days), completely immersed into artificial saliva and were stored under 37degrees C. Specimens of which the given immersion time elapsed were taken out and were poured with improved stone, making the stone specimens. Surface roughness of the stone specimens was measured by a profilometer. RESULTS: Within the limitation of this study, the following results were drawn. 1. Major influencing factor on surface roughness of the stone model made from tissue conditioner was the retention period (contribution ratio (rho) = 62.86%, P < .05) of the tissue conditioner in oral cavity to make functional impression. 2. In case of Coe-Comfort, higher mean surface roughness value of the stone model with statistical significance was observed compared to that of Soft-Liner and Visco-Gel as immersion time changes (P < .05). 3. In case of group L (less), higher mean surface roughness value of the stone model with statistical significance was observed compared to that of R (recommended) and M (more) group as immersion time changes (P < .05). CONCLUSION: We may conclude that as the retention period of time in oral cavity influences surface roughness of the stone model the most and as the kind of tissue conditioner and its P/L ratio may influence also, clinician should well understand the optimal retention period in oral cavity and choose the right tissue conditioner for the functional impression, thus making the functional impression with tissue conditioner usefully.

PURPOSE: The purpose of this study was to evaluate the difference in shear bonding strength between resin cements to dental materials when a universal primer (Monobond plus) was applied in place of a conventional primer. MATERIALS AND METHODS: Four groups of testing materials: gold alloy (Argedent Euro, n = 16), non precious metal (T-4, n = 20), zirconia (Cercon, n = 20) and glass ceramic (IPS e.max press, n = 20), were fabricated into discs, which were embedded in an acrylic resin matrix. The gold alloy specimens were airborne-particle abraded, 8 of the specimens were coated with Metal primer II, while the remaining 8 specimens were coated with Monobond plus. The non precious and zirconia specimen were airborne-particle abraded then, the control group received Alloy primer coating, while the other was coated with Monobond plus. Glass ceramic specimens were etched. 10 specimens were coated with Monobond-S and the remaining specimens were coated using Monobond plus. On top of the surface, Multilink N was polymerized in a disc shape. All of the specimens were thermal cycled before the shear bonding strength was measured. Statistical analysis was done with Two sample t-test or Mann-Whitney U test (alpha=.05). RESULTS: There were no significant differences in bonding strength depending on the type of primer used in the gold alloy and glass ceramic groups (P>.05), however, the bonding strengths of resin cements to non precious metal and zirconia groups, were significantly higher when the alloy primer was used (P<.05). CONCLUSION: Within the limitations of this study, improvement of universal primers which can be applied to all types of restorations is recommended to precious metals and zirconia ceramics. But, the bond strengths of non precious metals and zirconia ceramics were significantly lower when compared to a 10-MDP primer. More research is needed to apply universal primers to all types of restorations.

PURPOSE: The purpose of this study was to evaluate the fit of zirconia core using MAD/MAM system comparing to that of conventional metal-ceramic and CAD/CAM system. MATERIALS AND METHODS: Duplicating the prepared resin tooth, 50 improved stone dies were fabricated. These dies are classified as a group of 5 to create the core. The groups were composed of metal-ceramic, Cercon(R), Ceramill(R), Rainbow(TM), and Zirkonzhan(R). Each core was cemented to stone die, and then, absolute marginal discrepancy was measured with microscope at a magnification of x50. Statistical analysis was done with one-way ANOVA test and Tukey's HSD test. RESULTS: The mean absolute marginal discrepancy for metal-ceramic was 51.97 +/- 23.38 micrometer, for Cercon(R) was 62.16 +/- 25.88 micrometer, for Ceramill(R) was 67.64 +/- 40.38 micrometer, for Rainbow(TM) was 125.07 +/- 42.19 micrometer, and for Zirkonzhan(R) was 105 +/- 44.61 micrometer. CONCLUSION: 1. Fit of margin was identified as in the order of metal-ceramic, Cercon(R), Ceramill(R), Zirkonzhan(R), and Rainbow(TM). 2. Absolute marginal discrepancy of the zirconia core that designed by MAD/MAM system had significant differences in order of Ceramill(R), Zirkonzhan(R), and Rainbow(TM). 3. The mean absolute marginal discrepancy between Cercon(R) and Ceramill(R) did not show significant differences.

OBJECTIVE: The aim of this study is to measure the serum levels of CA 125, ESR and CRP in patients with tubo-ovarian abscess (TOA) before and after treatment of abscess and to assess the usefulness of CA 125 in the diagnosis, prediction of the outcome of TOA treatment and clinical follow-up of patient's condition. METHODS: This retrospective study included 65 patients with TOA. Serum CA 125, ESR, CRP and WBC counts were measured. The treatment was done conservatively with antibiotics. The patients were divided into two groups: those with successful results into group 1 (29 cases) and those with unsuccessful results into group 2 (36 cases). If treatment was considered to be unsuccessful, surgical intervention was additionally performed. RESULTS: The serum levels of CA 125, ESR and abscess size on admission in group 2 were significantly higher than in group 1. ESR, abscess size and CA 125 in order were valuable predictive factors affecting the success of medical treatment. And the new cutoff value was 36.5 mm/h, 4.2 cm and 68.3 U/ml, respectively. The sensitivity rate of CA 125, ESR levels was significantly higher in group 2 than in group 1. Although CRP was decreased significantly 10 days after treatment, the serum CA 125 was not decreased significantly. And it took 51.5 days for CA 125 to be normalized after the initiation of treatment. CONCLUSIONS: The serum CA125, ESR levels and abscess sizes are predictive factors affecting the success of medical treatment of abscess treatment. And CA 125 and ESR are useful for diagnosing severity of disease. But serum CA 125 level is an inappropriate marker for monitoring short-term efficacy of treatment.
