  • Purpose: To evaluate an effect of additional firing process after sintering of monolithic zirconia crown on marginal and internal fit through three-dimensional analysis. Materials and methods: Ten monolithic zirconia crowns were fabricated using titanium abutment model. Monolithic zirconia crowns were designed, milled, and sintered as a control group, and additional firing with coloring was performed as a test group. Three dimensional analysis were performed by using triple-scan protocol, and cross-section analysis on mesio-distal and disto-lingual section was evaluated to measure marginal and internal fitness. Then, three-dimensional surface difference on between two groups was evaluated (${\alpha}=.05$). Results: There was statistically significant difference between the control group ($32.0{\pm}24.3{\mu}m$) and the test group ($17.0{\pm}10.8{\mu}m$) in the mesial axial wall (P < .02) and the control group ($60.2{\pm}24.3{\mu}m$) and the test group ($71.8{\pm}21.5{\mu}m$) in the distal axial wall (P < .01). There was no statistically significant difference at the remaining point. Conclusion: There was no statistical significance on the deviation of inner surface of crown according to firing number, and the results of both group were considered clinically acceptable.

  • Background: Cardiopulmonary bypass during open heart surgery causes systemic inflammatory respose. IL-10 is an anti-inflammatory cytokine that inhibits inflammatory process and protects organ function by down regulation of pro-inflammatory cytokine release and maintenance of blood level balance with pro-inflammatory cytokines. Mateial and Method: Plasma IL-10 levels were measured and analyzed in 22 patients who underwent open heart surgery (11 cases of coronary artery bypass graft, 11 cases of valve replacement) under cardiopulmonary bypass since 1988 January to July at Department of Thoracic and Czardiovascular surgery, Yeungnam University Hospital. 1g of methylprednisolone was administrated to thirteen patients randomly. Blood samp.es were taken and collected at the time of induction of anesthesia, 10 min before cardiopulmonary bypass, 10 min after starting of CPB, 10 min aftr aortic cross clamping, 10 min after ACC release, and 10 min, 2 hours, and `5 hours after CPB respectively. The plasma levels of IL-10 were determined by enzyme-linked immunosorbent assays(ELISA). Wilcoxon-Raule Sum test was used for statistical analysis. Result: In all 22 patients, cardiopulmonary bypass time was used for statistical analysis. Result: In all 22 patients, cardiopulmonary bypass time was 171$\pm$41.4 min and aortic cross clamp time was 118$\pm$36.5 min. Peak IL-10 level was achieved at 10 min after ACC(361.0$\pm$52.81pg/ml) and was decreased sharply at 2 hours after CPB. Peak IL-10 level was correlated positively with aortic cross clamp time(p=0.011); however, it did not correlated with bypass time(p=0.181). In valve replacement group, mean IL-10 level at peak point was 567.89$\pm$107.69 pg/ml and was significantly higher than that of coronary artery bypass group(205.67$\pm$192.70 pg/ml)(p<0.001). ACC time in valve replacement group was significantly longer than that of coronary artery bypass group(p<0.01), however, bypass time was not(p=0.212). Thirteen patients with steroid pretreatment before starting of CPB showed relatively higher plasma IL-10 level than in control group, however, no statistical significance was noted(p=0.19). Conclusion: plasma level of IL-10 was increased in association with cardiopulmonary bypass and revealed peak at 10 min after ACC release. IL-10 level was correlated positively with ACC time. Therefore, systemic inflammatory respeonse in association with cardiopulmonary bypass could be decreased by reducing ACC time during cardiac surgery.

  • Background and Objectives : Although the incidence of allergic rhinitis has increased specific therapeutics with a certain medicine is not well developed yet. In therapeutics of allergic rhinitis, limited medicines just have been used in the clinin. Sochungyong-tang has been a widespread medicine for allergic rhinitis. However, okbyeongpung-san has been taken for raising immunity. In medical treatment of allergic rhinitis, raising immunity is a necessary part of the process. In this reason, this study aimed to find out therapeutic effects of combination of sochungyoung-tang and okbyeongpung-san extract on allergic rhinintis of nasal tissue in rats. Materials and Methods : The Sprague-Dawley male rats, about 200g of body weight, were divided into three groups: the normal group, the control groups, and the sample groups. With the Levine and Vaz method, the allergic reaction was induced with ovalbumin as antigen in the intraperitoneal route. Rats of the sample groups were treated with 2cc of sochungyoung-tang plus okbyeongpung-san extract once a day for 28days. I observed historical changes in nasal tissue. I also found changes in the segment of lympocyte and neutrophil of Leukocyte and erythrocyte. I used the statistical methods of post Hoc test(p<0.05) Results : The increase of the goblet cell and mucous secretion in the sample groups was rare when compared to the control groups. Effects of sochungyoung-tang plus okbyeongpung-san extract on the liver function were also studied in rats. Treatment of sochungyoung-tang plus okbyeongpung-san extract did not affect GOT and GPT. The number of lymphocyte was decreased, while the number of erythrocyte was increased in sample groups. Conclusion : This study shows that sochungyoung-tang plus okbyeongpung-san plus okbyeongpung-san extract has considerable effects on allergic rhinitis.

  • Changes in the physical and chemical properties of soil materials during the nursing process have a great influence on the quality of containerized seedlings and on growth and survival after planting. In this study, the effect of biomaterials and their mixed ratios on the growth of Zelkova serrata seedlings in a containerized seedling production system was investigated. Mushroom sawdust, pine bark, and carbonized rice husk were used as biomaterials. The mixed ratios were 10% and 20% volume ratio of the growing medium volume, including the untreated controls. There was no significant difference in the height growth of the Zelkova serrata seedlings according to the biomaterials. The root collar diameter was the highest with the 20% carbonized rice husk and the lowest with the mushroom sawdust. The difference between the highest quality index and the lowest quality index was 30% in the order of the carbonized rice husk, pine bark, control, and mushroom sawdust, but there was no statistical significance. In this study, if the growing medium mixed with biomaterials does not reduce the seedling growth compared with the control, it is considered that the biomaterial can replace a part of the growing media. Therefore, the results show that some of the growing media can be replaced with carbonized rice husk or pine bark when producing Zelkova serrata seedlings.

  • Coating thickness is one of target variables in quality control process in steel industry. To predict coating thickness and to control quality of anti-fingerprint steel coils, ultraviolet-visible spectra are measured. We propose a variable-interval selection procedure based on the variable importance in projection in partial least square model. Using the proposed variable interval selection method, prediction performance gets better in the reduced model than the full model with full spectra absorbance. It is also shown that the first differencing as a data preprocessing technique does work well for the prediction of coating thickness.

  • Cervical cancer is a major public health problem in Thailand, being ranked second only to breast cancer. Thai women have been reported to have a low rate of cervical cancer screening (27.7% of the 80% goal of WHO). We therefore aimed to apply the social marketing theory and health belief model in promoting cervical cancer screening in Kanthararom District, Sisaket Province. A total of 92 from 974 targeted women aged 30-60 years were randomly divided into two groups. The experimental group underwent application of social marketing theory and a health belief model program promoting cervical cancer screening while the control group received normal services. Two research tools were used: (1) application of social marketing theory and health belief model program and (2) questionnaire used to evaluate perceptions of cervical cancer. Descriptive and inferential statistics including paired sample t-test and independent t-test were used to analyze the data. After the program had been used, the mean score of perception of cervical cancer of experimental group was at a higher level (${\bar{x}}=4.09$; S.D.=0.30), than in the control group (${\bar{x}}=3.82$; S.D.=0.20) with statistical significance (p<0.001). This research demonstrated an appropriate communication process in behavioral modification to prevent cervical cancer. It can be recommended that this program featuring social marketing and the health belief model be used to promote cervical cancer screening in targeted women and it can be promoted as a guideline for other health services, especially in health promotion and disease prevention.

  • Objectives: The evaluation of iatrogenic dentinal defects in extracted teeth may be influenced by extraction forces and prolonged dry times. The purpose of this study was to compare the presence of dentinal defects in freshly extracted, periodontally compromised teeth with those in a group of teeth with uncontrolled extraction forces and storage time. Materials and Methods: The experimental group consisted of eighteen roots obtained from teeth extracted due to periodontal reasons with class II or III mobility. They were kept in saline and sectioned within 1 hour following extraction. The control group consisted of matched root types obtained from an anonymous tooth collection, consistent with previous dentinal defect studies. The slices were obtained at 3, 6, and 9 mm from the apex. The imaging process exposed all specimens to no more than 60 seconds of dry time. The ${\times}12.8$ magnification was used for the 9 mm slices and ${\times}19.2$ magnification for the 3 mm and 6 mm slices under light-emitting diode (LED) transillumination. The root canal spaces and periodontal tissues were masked to minimize extraneous factors that might influence the evaluators. Chi-square test was used for statistical analysis. Results: Dentinal defects were detected in 17% of the experimental group teeth, compared to 61% of control teeth (p = 0.015). Conclusions: LED transillumination assessment of freshly extracted roots with class II or III mobility showed smaller number of dentinal defects than roots with uncontrolled storage time and extraction forces. The use of freshly extracted roots with mobility should be considered for future dental defect assessment studies.

  • Purpose: Mucogingival defects (MGDs), such as dental root recessions, decreased vestibular depth, and absence of keratinized tissues, are commonly seen in dental clinics. MGDs may result in functional, aesthetic, and hygienic concerns. In these situations, autogenous soft tissue grafts are considered the gold-standard treatment. This study compares the healing process of free gingival grafts (FGGs) to bacterial cellulose matrix (BCM) and human acellular dermal matrix (ADM) seeded with fibroblasts from culture supplemented with platelet-rich plasma in a rat model. Methods: Surgical defects were made in rats, which received the following treatments in a randomized manner: group I, negative control (defect creation only); group II, positive control (FGG); group III, BCM; group IV, BCM + fibroblasts; group V, ADM; and group VI, ADM + fibroblasts. Clinical, histological, and immunological analyses were performed 15 days after grafting. Clinical examinations recorded epithelium regularity and the presence of ulcers, erythema, and/or edema. Results: The histological analysis revealed the degree of reepithelization, width, regularity, and presence of keratin. The Fisher exact statistical test was applied to the results (P<0.05). No groups showed ulcers except for group I. All groups had regular epithelium without erythema and without edema. Histologically, all groups exhibited regular epithelium with keratinization, and myofibroblasts were present in the connective tissue. The groups that received engineered grafts showed similar clinical and histological results to the FGG group. Conclusions: Within the limitations of this study, it was concluded that BCM and ADM can be used as cell scaffolds, with ADM yielding the best results. This study supports the use of this technical protocol in humans.

  • The purpose of this study is to find out the menopausal symptom of middle-aged women and their self-care on it. This study also intended to awaken the relationship of the menopausal symptom and self-care and to provide basic data on the health education of middle-aged women. For this purpose, the study (1) identified respondents background variables, (2) found menopausal symptom and the state of self-care, (3) analyzed relationship between general character, menopausal symptom, and self-care, (4) analyzed the relationship of menopausal symptom and self-care for 543 random sampled women in City of Incheon. The questionnaire consisted of 25 questions on the menopausal symptom interview by Neugarton translated by Jung Hae Ran(1985) and questions of the self-care inventory by Orem reconstructed by Sung Moon Hee(1988). The data were analyzed by using frequency, percentage, t-test, X²-test, pearson's correlation coefficient with SPSS statistical package. The results of this study could be summed up as follows ; 1. The Degree of menopausal symptom were graded from 25 to 75. (x 40.85, s. d. 8. 6.) 2. The test of relationship between the individual background and the menopausal symptom revealed that there seemed to be statistically significant correlation between the sexual life, life-content, the level of education, menstruation(p<0.000). 3. In the test of relationship between the individual background and the self-care process, (1) in case of insight of symptom, there seemed to be statistically significant correlation between the self-content(r=0.1463), sexual life(r= -0.1376), menstruation(r=0.1561), and artificial abortion(r=0.1577), (p<0.001), (2) In case of self-health control, there seemed to be statistical correlation between the states of menstruation and the number of induced abortion. (3) In case of self-health decision, there seemed to be statistically significant correlation between the number of visiting hospitals or clinics and the level of education(r=0.106), the self-content(r=0.1235), induced abortion(r=0.1343) (p<0.0000). And also individual background can show the 40.21 percent of self-health maintenance. 4. The relationship between menopausal symptom and self-care has a significant meaning to the insight of symptom, self-health decision according to the groups of menopausal symptom(p<0.000), but it doesn't have any meaning to self-health control. And self-health maintenance can manifest the 19.88 percent of menopausal symptom.
