The purpose of this study was to perform the fetal education effectively for the delivered woman and her husband. This study was conducted by the questionnaire survey on 199 delivered women and their 171 husbands at several hospitals located in Seoul and Kyonggi Province from February 28 to March 26, 2002. The contents of questionnaire included the purposes, the cognition and the practice of fetal education. The SAS program was used for the statistical analysis of the data. The character of subject was analyzed by the percentage. The difference between the cognition and practice of fetal education was analyzed by t-test, ANOVA, Wilcoxon rank sum test. The factor analysis affected on the practice of fetal education was adopted by Multiple regression. The results were as follows; 1. In the purpose of fetal education, the well- balanced emotion showed the highest mark. The cognition of fetal education(woman:$4.39{\pm}0.52$, husband:$3.88{\pm}0.70$) and the practice (woman:$3.88{\pm}0.60$, husband:$3.83{\pm}0.70$) showed the relatively high mark, but the score of cognition showed higher than that of practice. 2. In the comparison of the cognition between the delivered woman and the husband for the fetal education the item of the mental or health state would affect unborn baby, which occupied the highest mark in both woman and the husband(woman:$4.81{\pm}0.44$, husband:$4.81{\pm}0.50$). But they were prohibited to eat the deformed food, which showed the lowest mark(woman:$3.19{\pm}1.12$, husband:$3.21{\pm}1.29$). 3. In the comparison of the practice for the fetal education between the delivered woman and the husband, the practice for the healthy baby showed the highest mark in woman ($4.51{\pm}0.71$), which had a statistically significant difference(P=0.025), compared with that of the husband($4.13{\pm}0.99$). 4. In the comparison of cognition and practice for the fetal education, the general character was associated with the duration of marriage, the satisfaction with marriage and the support of husband on pregnancy. The mark was associated with the age of woman, the level of education and the first birth. 5. The significant factors influencing on the practice for the fetal education were connected with the cognition of fetal education, age, satisfaction with marriage, the support of husband on pregnancy, the type of family, the experience of delivery and the state of health during the period of pregnancy. etc. In conclusion, it is indicated to make effort for transforming and developing the traditional fetal education in accordance with the modern fetal education. And it is suggested that the fetal education might be recognized by all members of family, and the importance of husband's role for the fetal education should be informed as well as that of woman's.

The purpose of this study was to compare the marginal fit of all ceramic crowns prepared from alumina slip casting, which is consistent with the conventional In-ceram system, and those fabricated from alumina tapes which is currently under development in an effort to alleviate complexities involved in the forming procedure of the In-ceram crown core. All ceramic crowns, made of In-ceram(slip casting) and alumina tapes(Doctor blade casting), were prepared with $90^{\circ}\;and\;135^{\circ}$ shoulder margins. The crowns were cemented with a glass ionomer cement and embeded in epoxy resin. The embedded crowns were sectioned faciolingually and mesiodistally and marginal discrepancies and marginal gaps were measured under the Measurescope MM II. The measurements were analyzed using Wilcoxon rank sum test and Kruskal-Wallis test and the results were as follows: 1. In the case of $90^{\circ}$ shoulder margin, the combined marginal discrepancies and marginal gaps were $78.3{\mu}m\;and\;44.4{\mu}m$ respectively, for the all ceramic crowns fabricated using the alumina tapes. In comparison, the values were $65{\mu}m\;and\;25.5{\mu}m$ for the In-ceram crowns. For the marginal gaps a statistical difference existed (p<0.05) but no significant difference was observed for the marginal discrepancy (p>0.05). 2. In the case of $135^{\circ}$ shoulder margin, the combined marginal discrepancy and marginal gaps were $82.1{\mu}m\;and\;40.2{\mu}m$ respectively, for the all ceramic crowns formed with the tapes. As compared with the marginal discrepancy and gaps of the $90^{\circ}$ shoulder margin in the fabricated from the alumina tapes, no significant statistical differencies were discerned in both cases (p>0.05). 3. There was no statistically significant difference in the fits among four locations around the margins of the all ceramic crowns fabricated using the alumina tapes. The results obtained in this study showed that the marginal fits of the glass infiltrated alumina cores fabricated from the alumina tapes are slightly higher value than those prepared using the In-ceram but the difference is within a clinically acceptable range.

This study was performed 1) to compare the nature of the synchronized behaviors in mother-child plays between autistic and normal groups quantitatively and qualitatively and 2) to identify the behavioral data to improve synchrony. The subjects were consisted of 20 mother-child pairs, 10 for each autistic group(AG) and normal group(NG). The developmental age of two groups was under 24 months old and equally matched. Data were collected by video-taped mother-child free play and analyzed with Wilcoxon Rank Sign(Sum) Test, Spearman Correlation Coefficient, Scheffe's Test, and Content Analysis. The score on synchronized behaviors of AG was significantly lower than that of NG(p<.05). As time progressed, the difference was much higher between the 2 groups. And the structure of motherchild plays in AG was poor and most of the interactions were discontinued as 1 or 2 episodes. On the other hand, mother-child plays in NG were enriched and became somewhat like game or play. The score of mother's growth-fostering nurturing behaviors showed positive relation to synchrony and much highly related to the group of 16 months-old or above. Mother's laughing and patting responses and pausing to get the child's initiative were especially related highly to synchronized behaviors. In conclusion, these mother's growth-fostering nurturing behaviors should be stressed at the mother-child interactions and also well structured therapeutic play with considering in children's developmental level should be given.

The purpose of this study was to compare microleakage and marginal hybrid layer in class V restorations using two one-bottle adhesives and one self-etching adhesive. Class V cavity preparations with occlusal margins in enamel and gingival margins in dentin were pre-pared on buccal and lingual surfaces of 30 extracted human molar teeth. Prepared teeth were randomly divided into three treatment groups (n=30) and restored with three adhesives and composites: Single Bond/Filtek Z-250 (Group 1), Prime&BondNT/Esthet.X (Group 2), UniFil Bond/UniFil F (Group 3). For microleakage, samples were stored in room temperature water for 24 hours, thermocycled stained with 2% methylene blue dye, sectioned into halves, scored and analysed using Mann-whitney test and Wilcoxon signed rank sum test. For marginal hybrid layer, samples were sectioned into halves, treated with 10% phosphoric acid for 5 seconds, stored in 5% NaOCL solution for 24 hours, dried and gold coated. Occlusal and gingival margins of each sample were inspected under SEM. The results of this study were as follows ; 1. Microleakage at the occlusal margins was not evident in group 1 and group 2, but it showed in group 3 (p<0.05). 2. Microleakage in group 1 and group 3 was significantly lower than in group 2 at gingival margins (p<0.05). 3. Microleakage at gingival margins was greater than at occlusal margins in group 1 and group 2, but microleakage at occlusal margins was greater than at gingival margins in group 3 (p<0.05). 4. In group 1 and group 2, no gaps at occlusal margins showed. But gaps showed in group 3. Occlusal margins were free from a hybrid layer in all groups 5. The thickness of the marginal hybrid layers was 2.5~5 $\mu\textrm{m}$ thick in group 5 $\mu\textrm{m}$ thick in group 2 and 1.5 $\mu\textrm{m}$ thick in group 3. 6 There was no corelation between microleakage and thickness of marginal hybrid layer. In coclusion, the effect of dentin adhesives on microleakge in class V composite restorations was excellent when one-bottle adhesives were applied on enamel margin, and it was good when a self-etching adhesive was applied on dentinal margin. There was no corelation between microleakage and thickness of marginal hybrid layer.

Purpose: Most terminally ill cancer patients die from cancer anorexia-cachexia syndrome. This study evaluated a prognostic role of plasma leptin levels in terminally ill cancer patients. Methods: This study enrolled 69 terminally ill cancer patients who were aged above 20 years old from July 2009 to July 2010. For univariate analysis, an association between leptin levels and patient's characteristics or other variables was examined using Spearman's correlation analysis, Wilcoxon's rank-sum test or Kruskal-Wallis test, as appropriately. For multivariable analysis, Cox's proportional hazard regression model was used to evaluate a clinical significance of plasma leptin levels as a prognostic factor and to determine factors which affect the risk of death in terminally ill cancer patients. Results: A statistically significant positive correlation between plasma leptin levels and survival time was found. Univariate Cox's proportional hazard regression analyses also showed a moderately significant association between plasma leptin levels and survival time. However, after adjusting variables for sex, white blood cell counts, total bilirubin, AST, ALT, albumin and CRP levels, plasma leptin levels were not significantly associated with survival time. Conclusion: No significant association was found between plasma leptin levels and survival time in terminally ill cancer patients. However, this study suggested a prognostic value of plasma leptin levels in gastrointestinal cancer patients.

Purpose To compare the MR findings of septic and acute gouty arthritis of the knee joint. Materials and Methods This retrospective study included patients who underwent knee MRI for septic or gouty arthritis at our hospital between October 2012 and October 2018. The MR findings were analyzed for the presence of bone marrow edema, soft tissue edema, abscess, pattern of synovial thickening (frondlike, lamellated, diffuse linear), maximum thickness of the synovium, and joint effusion volume. The gouty (n = 5) and septic arthritis (n = 10) groups were compared using the Wilcoxon rank-sum test and Fisher's exact test. Results No statistically significant differences were observed for each item. One patient in the gouty arthritis group and seven in the septic arthritis group had bone marrow edema. Soft tissue abscess formation was only observed in the septic group. The incidence of each synovial thickening pattern was as follows: 100% (diffuse linear) in the gouty arthritis group and 20% (frondlike), 50% (lamellated), and 30% (diffuse linear) in the septic arthritis group. Conclusion Differentiation of gouty arthritis and septic arthritis based on imaging findings is difficult. However, lamellated synovial thickening patterns, bone marrow edema, and soft tissue abscess formation are more commonly observed in patients with septic arthritis than in those with gouty arthritis.

Background: The correlation between levels of brain natriuretic peptide (BNP) and the effect of pulmonary resection on the right ventricle of the heart is not yet widely known. This study aims to assess the relationship between the change in hemodynamic values of the right ventricle and increased BNP levels as a compensatory mechanism for right heart failure following pulmonary resection and to evaluate the role of the BNP level as an index of right heart failure after pulmonary resection. Material and Method: In 12 non small cell lung cancer patients that had received a lobectomy or pnemonectomy, the level of NT-proBNP was measured using the immunochemical method (Elecsys $1010^{(R)}$, Roche, Germany) which was compared with hemodynamic variables determined through the use of a Swan-Garz catheter prior to and following the surgery. Echocardiography was performed prior to and following the surgery, to measure changes in right ventricular and left ventricular pressures. For statistical analysis, the Wilcoxon rank sum test and linear regression analysis were conducted using SPSSWIN (version, 11.5). Result: The level of postoperative NT-proBNP (pg/mL) significantly increased for 6 hours, then for 1 day, 2 days, 3 days and 7 days after the surgery (p=0.003, 0.002, 0.002, 0.006, 0.004). Of the hemodynamic variables measured using the Swan-Ganz catheter, the mean pulmonary artery pressure after the surgery when compared with the pressure prior to surgery significantly increased at 0 hours, 6 hours, then 1 day, 2 days, and 3 days after the surgery (p=0.002, 0,002, 0.006, 0.007, 0.008). The right ventricular pressure significantly increased at 0 hours, 6 hours, then 1 day, and 3 days after the surgery (p=0.000, 0.009, 0.044, 0.032). The pulmonary vascular resistance index [pulmonary vascular resistance index=(mean pulmonary artery pressure-mean pulmonary capillary wedge pressure)/cardiac output index] significantly increased at 6 hours, then 2 days after the surgery (p=0.008, 0.028). When a regression analysis was conducted for changes in the mean pulmonary artery pressure and NT-proBNP levels after the surgery, significance was evident after 6 hours (r=0.602, p=0.038) and there was no significance thereafter. Echocardiography displayed no significant changes after the surgery. Conclusion: There was a significant correlation between changes in the mean pulmonary artery pressure and the NT-proBNP level 6 hours after a pulmonary resection. Therefore, it can be concluded that changes in NT-proBNP level after a pulmonary resection can serve as an index that reflects early hemodynamic changes in the right ventricle after a pulmonary resection.

Anterior subcapsular cataract was developed by opacification with transdifferentiation and abnormal proliferation of lens epithelial cells (LECs) and pathological accumulation of extracellular matrix (ECM). After-cataract also be caused by a similar transdifferentiation of LECs remaining after surgery and the accompanying increase of ECM deposits. It is blown that prostaglandin E2 and cytokine, such as TGF-$\beta$, bFGF, and IL-1, were associated with abnormal proliferation and transdifferentiation of LECs. The aim of this study was to detect the expression of transforming growth factor-$\alpha$ (TGF-$\alpha$), transforming growth factor-$\beta_1$(TGF-$\beta_1$) and basic fibroblast growth factor (bFGF) in LECs of senile and diabetic cataract. The expressions of these growth factors in lens epithelial cells were determined. The sample for growth factor determination were collected in senile cataract patients without metabolic disorder, especially diabetes mellitus and diabetic cataract patients. The mRNA expression of growth factors was detected by semi-quantitative reverse transcription - polymerase chain reaction (RT-PCR) followed by Southern blot analysis. Statistics were analysed using Wilcoxon rank sum test. Semi-quantitative RT-PCR/southern analysis of RNA obtained from thirty surgical specimens demonstrated that the level of mRNA expression of TGF-$\alpha$, -$\beta_1$ and bFGF was increased in diabetic cataract lens tissues compared with senile cataract specimens but non-significant, bFGF and TGF-$\beta_1$ mRNA expression were detected in most patients, expression level of TGF-$\beta_1$ was most high on the basis of normal ocular concentration. Detection rate of TGF-$\alpha$ in diabetic cataract was 1.5 fold higher than in senile cataract (P=0.098). TGF-$\alpha$, TGF-$\beta_1$, and bFGF mRNA expression of LECs were detected in senile and diabetic cataract. In both patient groups, expression level of TGF-$\beta_1$, mRNA was high, so We suggest TGF-$\beta_1$ strong influence in development of senile cataract and of diabetic cataract also. TGF-$\alpha$ expression level was similar but more frequently detected in diabetic cataract than in senile cataract. In conclusion, TGF-$\alpha$ may be associated with early development of diabetic cataract.

Muscle stiffness, pain and discomfort in dally activities are cardinal symtoms on arthritis. To reduce these symtoms, a nonequivalent one-group pre & posttest experiment was carried out at a rural community health post area in Chonbuk province during eight weeks (from 25th of January to 20th of March, 1999). The subjects were sixteen rural old women(65-89yrs) with osteoarthritis. And to reduce the level of pain, discomfort in daily living and to increase that of life satisfaction, 30 minutes of flexibility exercise followed by $15{\sim}20\;minutes$ of local heat therapy were done three times a week. Pain scale from Arthritis Impact Measurement Scales developed by Meenan(1980) for pain, Jette's Daily Activity Discomfort Scales revised by Lee(1988) for discomfort and Life Satisfaction Scales developed by Youn(1982) for life satisfaction were used as research instruments. The data were collected by face-to-face interviews with Investigator and the experiments were done under demonstration and supervision of investigator in community health post. The data were analyzed in percentage and Wilcoxon sign rank sum test by SPSS/PC+ program. The result could be summarized as follows ; 1. The scores of experiment group who were applied hot bag followed by flexibility exercise were tended to be significant lower in the level of pain statistically(Z=4.949, P=0.0001). 2. The scores of experiment group who was applied hot bag followed by flexibility exercise were tended to be significant lower in the level of discomfort in daily living statistically(Z=2.7226, P=0.0279). 3. The scores of experiment group who was applied hot bag followed by flexibility exercise were tended to be higher in the level of life satisfaction, but there was no significant statistical difference(Z=-1.2087, P=0.2171). In conclusion, flexibility exercise with local heat therapy could be identified as an effective therapy to reduce pain and discomfort in daily living of the rural elderly with osteoarthritis. And as a community health practitioner, the investigator concluded that this exercise with local heat therapy could be developed as a health promotion program for the rural aged people.

The purpose of this study was to investigate the correlation between the knowledge and educational needs related to recurrent in coronary artery bypass graft patients as a basis to provide an individual nursing education for the population. The subjects consisted of 110 patients who had coronary artery bypass graft(CABG) at Asan Medical Center in Seoul and Sechong hospital in Buchon. Data was obtained from a knowledge questionnaire and a learning needs questionnaire between November 1998 and February 1999. Data were analyzed using SAS program for Wilcoxon rank sum test and Spearman correlation coefficient. The results were as follows : 1. With regard to the 18 items to measure knowledge, the mean (median) of items 'don't know' was 4.9(4) items. The mean (median) of items answered wrong was 3.2(3) items. The number of items answered 'don't know' tend to show higher in those who had less education, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension 2. With regard to the level of knowledge by questionnaire about CABG, The most "I dont know" (59.1%) highly response was 'He has to be treated with anticoagulant drug to prevent revasculized vessel from obstructing.' The seond highest response (56.4%) was 'If you were hypotensive, the coronary attack would collapse. 'During the hospitalized day, the patient has complete bedrest.' The highest error probability was cholesterol has not to intake.', 'After surgery, the sexual life is need controlled for 1 year. 3. The mean of educational needs was 3.38. With regard to the level of learning needs by sentence about CABG, 'Food that benefit heart disease', 'Recurrence possibility of heart disease', 'Management method of operation site', 'Risk symptom that visit hospital or report immediately' were higher than other sentenses. With regard to the level of learning needs by factor 'food(5 items)', 'disease(9 items)' and 'exercise(3 items)' showed the highest than other factors. The educational needs by patients characteristics tend to show higher in males, under the age of 49, middle or high school degree, previous experience of admission with coronary artery disease, history of myocardial infarction, expierience of PTCA, history of cerebro-vascular accident, previous expierience of smoking than in their counter parts. 4. The number of items answered 'don't know', wrong and correct weren't correlated with the level educational needs. As the results, the number of items answered 'don't know' tend to show higher in those who had less educated, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension .There were higher frequency of items answered 'don't know' on anti-thrombolitic theraphy, hypotension and pain relief. Also there were higher frequency of items answered wrong on bed rest period, cholesterol intake, and sexual life. Educational needs were higher in young age group, had previous experience of procesure and history of other disease. And when we educate CABG patients, education for diet, recurrence possibility of disease, management methods of operation site and risk symptom should be emphasized.
