BACKGROUND: The purpose of this study was to identify the attitude of physicians stemming from their experiences of caring for potential brain death donors during the organ donation process. METHODS: Grounded theory methodology was used for this study. In depth interviews were conducted with six physicians who had experience of management of potential brain death donors. Data collection was done from January to October 2011. Theoretical sampling was used until the data reached saturation. RESULTS: As a result of the analysis, dilemma of organ donation solicitation was identified as the core category. Twelve subcategories were identified and they were integrated to the core category. Obtaining organ donation counseling skills was identified as the consequence. CONCLUSIONS: The results of the study will provide a frame for understanding the attitudes stemming from their experience of caring for potential brain death donor and helping the development of effective intervention strategies for increasing organ donation.

The purpose of this study is to estimate cesarean section rate in Korea and analyze the socioeconomic variables and health resources which affect regional variation in the rate. Samples were drawn from the record of vaginal and cesarean section deliveries based upon insurance claim bills which have been submitted to the National Federation of Medical Insurance for the first three months, January through March, 1991. The results are obtained as follows: It was found that, cesarean section rate was increasing rapidly up to 23.1% in 1991. Cesarean section per 10 thousand insured people was 4.8 and the number of cesarean section per 10 thousand insured eligible(15-49 years old) female was 7.6. The fee for normal delivery was 109,489 won and that for cesarean section was 390,024 won. The average days of hospitalization in normal delivery was 2.3 days, and those in cesarean section was 7.6 days. On the average cesarean section has a longer of stay as much as by 4.3 days and cost 3.6 times more than normal deliveries. Cesarean section rates vary among medical facilities: 19.8% at clinics 37.6% in small-scale hospitals, and 29.1% in general hospitals. The regional variation of cesarean section rates was also fairly prominent. The South Cheju Gun has the highest rate of cesarean section, 56.2%. Meanwhile no cesarean section cases has been reported in Sunchang Gun during the period of this study. The variation is noted among provinces. The rate for Cheju province has been 3.4 times higher than that for Chunnam. The number of cesarean section per 10 thousand insured people vary greatly among regions, too. This study has found that there exists significant regional variations among various geographic units in terms of average length of stay, average cost, number of obsretricians and number of beds. Multiple regression analysis was done to identify factors explaining the regional variance of various cesarean section rates: In the urban areas, no significant explaining variables were noted except the number of beds for the dependent variable of cesarean section cases per 10 thousand insured eligible females. The smaller the number of bed, the more cases of cesarean section was noted for an urban area. The is mostly because the rate of cesarean section is higher in medium-size hospitals than in large general hospitals. In the rural areas, the factor of education has been found significant for all three dependent variables. The higher the educational level, the rate of cesarean section is most likely to rise. An income variable measured by the amount of monthly insurance contribution has been identified a powerful predictor in explaining the variance of cesarean section rates. The same has been noted for the number of obstetricians. Similar findings are observed for the country as a whole. The income level has been found as the most powerful explaining factor in the regional variance of cesarean section rates. In general the rate is higher in the urban areas, and lower in the area with more small hospitals. As this is the initial attempt to identify the factors relevant to the regional difference in the rates of cesarean section, more elaborated study is urgently required.

This study was focused on the distribution of different facial types of the Class II division 1 malocclusion groups and skeletal characteristics of the each group and those that anteropsterior relationship of the maxilla and mandible calculated from the analysis of ANB angle and Wits appraisal was quite different from each other, as well. Cephalometric headplates of 140 persons of Class II division 1 malocclusion whose mean age was 11.2 years and 69 persons of normal occlusion whose mean age was 12.2 years were utilized as materials. Measurements were recorded, tabulated and statistically analyzed employing the tracings of the lateral cephalograms, then Class II division 1 malocclusion group was divided into 9 Types according to the angle of SNA and SNB for the anteroposterior relationship of the maxilla and mandible, another 9 Types according to the FH-NPog and SN-MP for the horizontal and vertical relationship, and the other 9 Types according to the ANB and Wits appraisal for intermaxillary relationship as well, with which was based on Mean+/- 1SD of those of normal occlusion. The result allowed the following conclusion: 1. 37.1 % of population demonstrated maxilla within normal range and retrognathic mandible to the cranial base, 30% for both maxilla and mandible within normal range, 20% for retrognathic maxilla and mandible and 12.9 % of the rest were arranged in Class II division 1 malocclusion groups. 2. Retrognathic mandible and hyperdivergent face accounted for 30.7 %, mesognathic mandible and neutrodivergent face for 29.3 %, mesognathic mandible and hyperdivergent face for 16.4 %, retrognathic mandible and neutrodivergent face for 13.6 %, mesognathic mandible and hypodivergent face for 10% of population were computed in Class II division 1 malocclusion groups. 3. It was suggested that skeletal Class II malocclusion might be due to anomaly in size and shape of cranial base, underdevelopment of mandible, retropositioning of mandible, underdevelopment of posterior face against anterior face, or any combination of these factors. 4. Population with underdevelopment and/or retropositioning of the mandible showed hyperdivergent tendency of facial profile. 5. The ANB angle and Wits appraisal did not coincide the severity of anteroposterior dysplasia in 35.7% of Class II division 1 malocclusion group each other, and this inconsistency was suggested to be related with mandibular rotation, inclination of cranial base, and anteroposterior position of the maxilla.

The purpose of this study was to compare bracket shear bond strengths of th crystal growth solutions wi those of the 37% phosphoric acid etch technique. The 4 crystal growth solutions were made experimentally in th lab, that is (1)30% polyacrylic acid solution containing 0.3 M sulfuric acid (ES 1), (2)30% polyacrylic acid solution containing 0.6 M solution acid (ES 2), (3)30% polyacrylic acid solution containing 0.3 M solution acid and 0.6M lithium sulfate(ES 3), (4)30% polyacrylic acid solution containing 0.3 M solution acid and 5% phosphoric acid (ES 4). The 37% phosphoric acid solution used as a control. Bovine lower incisor tooth enamel was treated by the above solutions for 60 sec, washed out for 20 sec with slow water stream, and bonded lower anterior edgewise bracket with the light curing orthodontic composit resin adhesives. The teeth bonded brackets were stored in the distilled water at room temperature for 24h, and followed to test the bracket shear bond strength. The acid etch technique showed 177.6kg/cm(2) of mean shear bond strength which was the highest among the enamel treatment solutions. ES 1 shown 58.4 kg/cm(2) of mead shear bond strength and the of ES 4 showed 66.5 kg/cm(2). There was no significant difference between the two(p>0.05). Es 2 showed 110.6kg/cm(2) of mean shear bond strength which was 62.3% of that of acid etch technique. ES 3 showed 131.3kg/cm(2) of mead shear bond strength which was the highest among experimental crystal growth solution and which was 74% of that of acid etch technique. The shear bond strengths of the crystal growth solutions and were significantly lower that that of acid etch technique(p<0.05). The results suggest that bracket shear bond strength of 30% polyacrylic acid solution containing 0.3M sulfuric acid and 0.6M lithium sulfate were showed the highest, it is low for the clinical application of this solution.

Highly specific and sensitive immunoassay method for soluble human recombinant interleukin-6 (hu rlL-6) was established by two different immunization methods. One is conventional method by Freund's adjuvant method and the other is special method which is directly injected to mouse spleen. Among seven established monoclonal antibodies (mAbs), two typical monoclonal antibodies, designated YB3 (IgG1) and NY2 (IgM), were further characterized. These mAbs highly bound to IL-6, however did not show cross reactivity with IL-1B and IL-2. As the results of ELISA inhibition assay and western blotting method, it was further identified that YB3 and NY2 had high binding specificity with IL-6. And the limiting detection amount of rlL-6 for YB3 was 5 ng/ml and for NY2 was 0.5 ng/ml. Furthermore, N-glycosylated human rlL-6 was also bound to YB3 on ELISA. On the other hand YB-3 furtherly recognized N-glycosylated human rlL-6 by sandwich ELISA method. These mAbs may be of use to diagnose the gynecopathy which contains abortion and preterm labor.

This study was performed to evaluate the semiquantitative food frequency questionnaire used to obtain information about. dietary patterns of adults in a rural county, Yang-pyeung Gun. The study population was 1311 adults aged 17~85 years. And well-trained interviewers interviewed subjects in 1990, 1992, 1993. The results are as follows. 1) Nutrients intake calculated from each questionnaire showed significant difference, because the number of question was not same(fifty questions in 1990, eighty questions in 1992, 1993). 2) Estimated nutrients intake from separate food items was significantly different when food items are combined in one question. 3) The agreement of nutrients intake level except vit C were high when the subjects are cross-classified by their ranks on the nutrients intake level from items in both questionnaires and on the nutrient intake level from items in each questionnaire. 4) And analysing this study data by multiple stepwise regression, we selected twenty seven food items whic could explained over 85% of inter-individual variation of nutrients(energy, carbohydrate, fat, protein, vit A, vit B1, vit B2, vit C, Ca). From above results, we suggested that it is neccessary to standardize questionnaire and perform validity studies.

Eccrine acrospiroma is a rare adnexal tumor of the skin. When the clinical presentation is that of a breast lump, diagnosis can be difficult. Also, most of the cytopathologists are not familiar with the cytologic features of this tumor and this is responsible for diagnostic pitfalls. We experienced a case of eccrine acrospiroma of the right breast in a 41-year-old female, misdiagnosed by fine needle aspiration cytology(FNAC). FNAC was characterized by tight clusters or sheets of small round cells, polygonal cells, and spindle cells and tubule like structures within clusters. Myoepithelial cells were not noted in the clusters. The diagnosis of eccrine acrospiroma was confirmed by histology.

PURPOSE: This study aimed to investigate knowledge of and compliance with the neutropenic diet in hemato-oncology patients undergoing chemotherapy. METHODS: 123 hemato-oncology patients who had more than one chemotherapy participated in this study. Data were collected with a self-administered questionnaire from July 21 to September 26, 2014, and analyzed with SPSS 21.0 program using descriptive statistics, t-test, ANOVA and Pearson's correlation. RESULTS: The average of score for the neutropenic diet was 60.9 out of 100 points and mean compliance score was 69.5 out of 100 percent scale. For preventing infection, patients were found to be stricter in their intake of restricted foods than acceptable foods during neutropenia. There were significant correlations between the knowledge of and compliance with the neutropenic diet in patients receiving chemotherapy (r=.53, p<.001). CONCLUSION: It is necessary to nursing assessment and education should include a periodic assessment of nutritional status and risk evaluation of neutropenia and bacterial infections. This study recommended nursing research to establish a recommendation criterion for a restrictive neutropenic diet and less restrictive food safety education programs for cancer patients.
