The study of the validity test on the self-monitoring scale for nurses In this study. both the literary survey as well as empirical research has been executed to test the validity of the scales that measure the construct of the self-monitoring scale. The self-monitoring scale could not be classified into five factors as Snyder suggested. Many other scholars( Briggs, Cheek and Buss, 1580) suggested 3 different classifications which was accepted by Snyder and Gangestad (1986) , John, Cheek and Klohnen(1996) claimed a two -factor classification. As has been discussed. factor analysis is used to prove convergent validity within the (actor and discriminant validity between the factors. However, depending on the researchers, many variations in classification of the factors were found and a lack of content and discriminant validity were found in the previous research findings. It is also important to note that Snyder's self-monitoring scale did not factor-load at over . 30 for all 25 items, regardless of how many factors could be classified. According to findings of this study, the self-monitoring scale neither classified as five, three or two factors nor (actor loaded as hypothesized. It is also clear that Snyder's self-monitoring scale lacks convergent validity as the sub-(actors of the scale failed to prove its uni -dimensionality. The A self-monitoring scale not only fail to overcome the problems of Snyder's self-monitoring scale but even lost the attractiveness of the self-monitoring scale. In this study it was also found that the A self-monitoring scale was not classified in either in a two or three-factor classification as hypothesized. It is, of course, not desirable to use any scale that lacks convergent and discriminant validity even though it has been widely used and has held a great deal of influence on the field of social psychology. To overcome the shortcomings of Snyder's self-monitoring scale, Lennox and Wolfe(1984) suggested 13 items. This study was dedicated to test the validity and reliability of the scale, in which we found that the data presented in validity as the two factors were classified and loaded as expected. Reliability was also proven by checking Cronbach's alpha for each factor and for the total items. In addition a confirmatory factor analysis was executed for the 13items using M SREL 8.12 program to confirm convergent validity in a two-factor classification. The model was fitting and sound however, the self-monitoring scale was unfitted and not validated. Thus, it is recommended to use not the original nor the abbreviated self-monitoring scale but the 13 items in future studies. It should also be noted that items 7 and 13 should be removed to obtain better mini-dimensionality for the 13 items. These items loaded at over .30, too high for the two factors in the test results of Factor analysis. In addition. it is necessary to double-check the cause of two-hold loading at over .30 for the two factors. It could be a problem caused by data or by the scale itself. Therefore, additional studies should follow to better clarify this matter.

This study was performed to develop a scale of maternal conflict based on already established scales and the literature review. The major purpose of this study was to develop a scale of which contains difficulties which mother can feel to rearing her child and can be applied to mothers at home or employed mothers. 68 items were developed. For content validity test, the items were examined by 7 experts panel with Likert 4 scale. The 39 items were selected as high validity from 86% of the experts. The item number of each area and the misunderstanding words were corrected by advices of experts. 10 mothers again examined 39 items in order to correct the misunderstanding words and the long sentences. For reliability and factor analysis of 39 items, 496 mothers participated. 34 items were chosen because 5 items that corrected item-total correlation coefficient were lower than 0.2 were excluded by the result of reliability analysis. Factor analysis was done with 34items. 6 factors were classified higher than eigen value 1.0, 28 items were chosen because 6 items that factor loadings were lower than 0.4 were excluded. These factors were named as employment and caring for child(6 items), child education(5 items), support system for caring for child(4 items), interaction with mother and child(4 items), view of maternal role(5 items) and me as human being(4 items). Reliability analysis was done with 28 items. 1 item(36 number of factor 1) was excluded because corrected item-total correlation coefficient were lower than 0.2. Therefore, 27 items were chosen. Maternal Conflict Scale was contained 27 items. The corrected item-total correlation coefficient of 27 items were ranged from .2345 to .5240 and Cronbach alpha coefficient of those was .8207 by the results of reliability analysis. It can be evaluated that this scale had a high validity and reliability because of passing through an objective process of test.

This study was designed to investigate effects of maternal education using Brazelton Neonatal Behavioral Assessment Scale(the following will be marked as NBAS) on the mother-infant interaction and infant behavior. The subjects of this study consisted of 48 pairs of normal mother and infant, 24 pairs for intervention group and 24 pairs for control group. The subjects were recruited from two general hospitals, and an OBGY clinic located in J city. The data were collected from July 30, 2001 to October 6, 2001. Prior to investigation and data collection, following operational hypotheses were set up in order to compare the investigative data against these operational hypotheses(H). H1: Intervention group will higher mother-infant interaction score than control group. H2: Intervention group infants will higher overall performance in infant behavior test score than control group infants. The results of this study were summarized as follows: 1. The mother-infant interaction score was 59.79 points in intervention group and 53.91 points in control group. The mother-infant interaction score of intervention group showed significant difference than control group. Therefore, hypothesis 1 was supported. 2. The infant behavior score of intervention group was significantly higher than control group, but partially. Therefore, hypothesis 2 was partially supported. 1) The social interaction(orientation) score was 46.58 points in intervention group and 43.50 points in control group. The orientation score of intervention group showed significant difference than control group. 2) The state regulation score was 26.79 points in intervention group and 25.33 points in control group. The state regulation score of intervention group showed significant difference than control group. In conclusion, present work demonstrated that maternal education using NBAS is an effective intervention method for promotion of mother-infant interaction and of infant behavior development. Author believes that many inexperience young mother may find NBAS-based maternal education beneficial for their nursing babies, therefore NBAS-based intervention is recommended to be adopted routinely as an integral part of neonatal nursing strategies.

Superior mediastinal widening, as seen on chest radiographs of traumatized patients, has been considered the hallmark of mediastinal injury. The usual causes of superior mediastinal widening are rupture of the aorta, esophagus or trachea, and hematoma as a result of spinal fracture. Posterior dislocation of the sternoclavicular joint is rarely a cause. We report a case of superior mediastinal widening resulting from traumatic posterior dislocation of the stern-oclavicular joint, and describe the CT findings, including those of 3-D imaging.

Guillain-Barré syndrome (GBS) is nowadays consider as an umbrella term that has heterogenous presentation depend on their subtypes. GBS is clinical diagnosis and its diagnosis can be supported by laboratory findings from cerebral spinal fluid study, nerve conduction study, anti-ganglioside antibodies, spinal magnetic resonance imaging and nerve ultrasound. Understanding atypical subtypes and GBS mimicking diseases are crucial for correct diagnosis. Both proper medical care for respiratory and autonomic dysfunction and immunotherapy are essential to improve outcome of GBS. Here, we summarized the current concept on diagnosis, immunopathophysiology and treatment of GBS.

Some of the pituitary prolactinomas were reported that they don't have active dopamine receptors and do not respond to bromocriptine which is a dopamine agonist. GH3 cell line which is derived from the rat pituitary tumor cells lacks affinity of dopamine receptors and secrete prolactin as well as small amount of growth hormone. Although it has been reported that epidermal growth factor (EGF) induces functional expression of dopamine receptors on GH3 cells in vitro, there has been a contradictory result. In the present study, EGF effect on the GH3 cell response to the bromocriptine was observed in order to investigate whether EGF induces dopamine receptor expression on dopamine resistant tumors in the absence of serum. GH3 cells were cultured for 4 days in the serum-supplemented medium (SSM) followed by culture in serum-free medium (SFM) with or without EGF. Additionally, effect of tamoxifen was also observed. EGF decreased the cell number and the ratio of cell division of GH3 cells while the ratio of prolactin-immunoreac-tive cells was increased. However, EGF did not show any significant effect on the GH3 cell response to bromocriptine treatment. Although tamoxifen decreased the GH3 cell number by increasing apoptosis, it did not influence GH3 cell response to bromocriptine. Our results indicate that EGF does not increase the affinity of dopamine receptors on GH3 cells and is not useful for the treatment of the dopamine-resistant prolactinoma.

This study was performed in order to establish the culture system optimal for the study on pituitary prolactin cells using growth factor and extra cellular matrix components as the culture substrate. The effect of epidermal growth factor (EGF) alone or along with extracellular marix components on GH3 cell growth and PRL expression was assessed using cell count, BrdU-immunocytochemistry and PRL-immunocytochemistry in in vitro cultures on plastic, laminin and Matrigel. EGF decreased the cell growth, BrdU-labeling and increased the PRL-immunoreactive cells regardless of the culture substrate by day 3 of the culture. Matrigel was the best culture substrate to decrease the cell growth and to increase the PRL expression. EGF treatment in the Matrigel culture showed about 80.5% of PRL-immunoreactive cells by day 6 of the culture. These results indicated that Matrigel is the better culture substrate than plastic or laminin to inhibit the overgrowth and to increase the prolactin expression of the GH3 cell and that EGF and Matrigel causes very effective culture environment for the long-term culture of the GH3 cell by synergistic mechanism.

This study was to find out whether the rendering screen difference affect to measuring distance in a CAD program according to three types of CAD programs. Materials and methods: The model presented in ISO 12836 for dental scanner evaluation was reduced by 70%. This model was repeatedly scanned 15times using Trios II (3Shape, Denmark). Using the output STL file, 3Shape CAD, inLab 15, and ExoCAD programs were used to measure the horizontal distance (H) and vertical distance (V) between adjacent point angle, and for each experiment, three groups were set according to the CAD program type. Statistical analysis was performed using One-way ANOVA test and post hoc was performed using Dunnett T3 test. Results: In the horizontal and vertical distance measurement, there was no difference in the average of the measured values between the three groups according to the CAD program (P>.05). Conclusion: There were no effect of the difference in the rendering screen in the horizontal and vertical linear distance measurements of the inlay model on the dental CAD program.

Purpose: The effects of circadian blood pressure (BP) alterations on the development and progression of microvascular complications in type 1 diabetes mellitus (T1DM) patients are unknown. We evaluated the effects of circadian BP alterations with development of microvascular complications during follow-up with patients with childhood-onset T1DM. Methods: We investigated the medical records of 81 pediatric patients with T1DM who underwent 24-hour ambulatory BP monitoring (ABPM) between January 2009 and February 2010. Results: Mean age at diagnosis and ABPM evaluation was 8.0±3.9 and 15.6±2.4 years, respectively. Hypertension (daytime, nighttime, and 24-hour mean hypertension) data were available in 42 patients. During the 8 years of follow-up after ABPM, microvascular complications occurred in 8 patients (diabetic retinopathy [DR] alone in 5, microalbuminuria alone in 2, and both in 1), of whom 7 had nondipper BP. Nighttime diastolic BP, nighttime mean arterial pressure, and glycated hemoglobin A (HbA1c) level were higher in patients with DR than in those without DR (P<0.05 for all). Daytime or nighttime BP and presence of dipper BP were not related to microvascular complications, but diabetic microvascular complications were more likely to occur in patients with an older age at diagnosis and higher HbA1c level. The proportion of patients with DR was higher in those with nondipper hypertension (83.3%) compared with dipper and nondipper normotension (0% and 16.7%, respectively; P=0.021). Conclusion As a predictor of microvascular complications, nondipper hypertension was not significant. Glycemic control rather than nondipper hypertension is the predominant factor determining DR in T1DM patients.

OBJECTIVE: The present study was conducted to evaluate the viability of germ cells form the adult and fetal ovarian tissues after vitrification followed by xenografting. METHOD: The human adult ovarian tissues were obtained from 33 years old patients, and the fetal ovarian tissues were obtained from 22 weeks and 25 weeks in gestation. ovarian tissues were cryopreserved by vitrification with 5.5 M ethylene glycol (EG 5.5) and 1.0 M sucrose as cryoprotectants. Adult and fetal ovarian tissues were pre-equilivrated with EG 5.5 at room temperature for 10 and 5 minutes, respectively and plunged into liquid nitrogen immediately. Frozen-thawed tissues were xenografted into NOD-SCID mice to evaluated the viability and capacity for further growth of the primordial follicles. Grafts were recovered from the recipients 4 weeks after transplantation and histological analysis was accomplished. RESULT AND CONCLUSION: Grafts recovered 4 weeks after transplantation contained less number of oocytes and primordial follicles compared to that of the fresh tissues. Survived follicles were mainly primordial and intermediary with larger diameter and more granulosa cells. It is confirmed that 1) the ovarian tissues were healthy and the germ cells were survived after vitrification, and 2) the survived fetal primordial follicles after vitrification resumed the growth in the xenofrafts.
