  • Purpose: This study was conducted to compare self-care behaviors and self-care behavior related factors for groups of patients with good, inadequate and poor glycemic control. The study was based on variables of the Theory of Planned Behavior by Ajzen, habit and family support. (1991). Methods: Participants were 134 patients with type 2 diabetes (good glycemic control group: 57, inadequate glycemic control group: 40, poor glycemic control group: 37). Self-care behaviors, intention to self-care behavior and self-care behavior related variables (attitude, subjective norms, perceived behavior control, habits and family support) were measured. Data were collected from August 12 to September 25, 2014 and were analyzed using $x^2$-test, Fisher's exact test, ANCOVA, and logistic regression with SPSS/WIN 21.0. Results: Among the three glycemic groups, there were significant differences in self-care behavior, subjective norms, perceived behavior control, family support, and habits. Multinomial logistic regression showed that poor blood glucose probability was associated with duration of diabetes mellitus, method of DM therapy, perceived behavior control and habits. Conclusion: The study findings reveal the important role of self-care behavior, subjective norms, perceived behavior control, family support, and habits in blood glucose control in adults with type 2 diabetes.

  • Background This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. Methods A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation. Results A significant increase in interincisal distance of 32 mm was seen in 12 (92.31%) patients in the T-plate interposition group, in 2 (25%) cases of the temporalis muscle flap interposition group, and in 1 case (14.28%) of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69%) of the T-plate interposition group, while as it was observed in 4 (50%) cases in the temporalis muscle flap interposition group and 4 (57.14%) cases in the condylectomy group, and these differences were statistically significant. Conclusions Our clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

  • Purpose: This study was conducted to examine the effects of simulation-based practice using standardized patients for the care of woman with postpartum hemorrhage as related to clinical performance competence and critical thinking deposition of nursing students. Methods: A nonequivalent control group pre-post test experimental design was used. Fifty four third year students were recruited, 29 students for the experimental group and 25 students for the control group. The simulation-based practice about nursing care related to postpartum hemorrhage included skill training, team-based practice, and debriefing. It was implemented with the experimental group for about 30 minutes in October 6, 2011. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability, and t-test using the SPSS/WIN program. Results: The experimental group who had the simulation-based practice showed significantly higher knowledge and skills of clinical performance competence than the control group (t=2.19, p=.003). But the experimental group who had the simulation-based practice did not show significantly higher critical thinking deposition than the control group (t=-0.32, p=.748). Conclusion: The results indicate that a simulation-based practice is an effective teaching method to improve knowledge and skills for clinical performance competence of nursing students. Further study is needed to identify the effect of a simulation-based practice on nursing attitudes.

  • This study was conducted to evaluate the difference of staphylococcal colonization between lactating mothers and nursery stares. Samples were obtained from the hands and noses of the newborn(admitted to S Univ. hospital's nursery from 1991. 5. 23 to 6. 8), their mothers and nursery staffs. They were cultured, and then the presence/absence of pathogenic staphylococci in them were analyzed by Fisher exact probability test which led to these conclusion of significance as follows: 1. No differences were detected in pathogenic rate of nasal swab culture between breast~fed newborns and formula-fed ones. 2. Delivery type and hospitalization the ones from the brest-fed newborns show high rate of Sta. aureus coa(+). In case of either C-sec delivery or long (more than 4 days) hospitalization, formula-fed ones in case of NSVD or short (less than 3 days) hospitalization. 3. The ones from breast feeding mothers show higher sta. aureus coa(+) than those from nursery staffs, which was of no significance statistically. Considering nursery staffs only, however, the comparison of those with the data in April indicates that the pathogen rate is higher for hand than nose, and Sta aureus coa(+) for hand is far lower in June than in April, which was statistically significant. These results lead us to infer that newborn infection in hospitalization could be largely reduced by maintaining the ordinary hygienes. Such as the handwashing of mothers as well as nursery staffs (directly involved in newborn care) Thus the pre-enterance hand washing of a mother who visits the nursery only for breast feeding (without any other medical responsibility) should be done, like other medical agents, with $0.05\%$ chlorhexidine antiseptics rather than simple soap cleansing; the one 'that is worth emphasizing thoroughly.

  • Objective : Intraoperative neurophysiological monitoring (IONM) has been widely used during spine surgery to reduce or prevent neurologic deficits, however, its application to the surgical management for cervical myelopathy remains controversial. This study aimed to assess the success rate of IONM in patients with cervical myelopathy and to investigate the factors associated with successful baseline monitoring and the effect of increasing the stimulation intensity by focusing on motor evoked potentials (MEPs). Methods : The data of 88 patients who underwent surgery for cervical myelopathy with IONM between January 2016 and June 2018 were retrospectively reviewed. The success rate of baseline MEP monitoring at the initial stimulation of 400 V was investigated. In unmonitorable cases, the stimulation intensity was increased to 999 V, and the success rate final MEP monitoring was reinvestigated. In addition, factors related to the success rate of baseline MEP monitoring were investigated using independent t-test, Wilcoxon rank-sum test, chi-squared test, and Fisher's exact probability test for statistical analysis. The factors included age, sex, body mass index, diabetes mellitus, smoking history, symptom duration, Torg-Pavlov ratio, space available for the cord (SAC), cord compression ratio (CCR), intramedullary increased signal intensity (SI) on magnetic resonance imaging, SI length, SI ratio, the Medical Research Council (MRC) grade, the preoperative modified Nurick grade and Japanese Orthopedic Association (JOA) score. Results : The overall success rate for reliable MEP response was 52.3% after increasing the stimulation intensity. No complications were observed to be associated with increased intensity. The factors related to the success rate of final MEP monitoring were found to be SAC (p<0.001), CCR (p<0.001), MRC grade (p<0.001), preoperative modified Nurick grade (p<0.001), and JOA score (p<0.001). The cut-off score for successful MEP monitoring was 5.67 mm for SAC, 47.33% for the CCR, 3 points for MRC grade, 2 points for the modified Nurick grade, and 12 points for the JOA score. Conclusion : Increasing the stimulation intensity could significantly improve the success rate of baseline MEP monitoring for unmonitorable cases at the initial stimulation in cervical myelopathy. In particular, the SAC, CCR, MRC grade, preoperative Nurick grade and JOA score may be considered as the more important related factors associated with the success rate of MEP monitoring. Therefore, the degree of preoperative neurological functional deficits and the presence of spinal cord compression on imaging could be used as new detailed criteria for the application of IONM in patients with cervical myelopathy.

  • Objectives : The purpose of this study was to analyze the influence which the professional dental hygiene education has on the knowledge and behavioral change for oral health to the students in the departments of dental hygiene. Methods : 771 students in the first grade and 646 students in the third grade who were attending the departments of dental hygiene from 12 colleges in Korea were surveyed. The self-administered questionnaires were distributed to the students in the colleges during May and asked them to answer the questions and then recovered them on the spot. The collected questionnaires were analyzed by using a SPSS/PC program and the difference of significance depending on the group of the students was tested by Chi-square test or Fisher's exact probability test. Results : In the number of eating snacks by the students during one day, 2-3 times was the highest, irrespectively of the grade. The rate of the students brushing their teeth after snack was higher in the third-grade students(34.8%) than in the first-grade students(20.8%). As the path of acquiring oral health knowledge, all of the first-grade and third-grade students replied that their school classes had impacted them the most. The rate of toothache experience was a higher tendency in third-grade students compared to the first-grade students(p=0.116). The rate of gingival bleeding experience was lower in the third-grade students than in the first-grade students. The rate of oral prophylaxis experience was higher in the third-grade students than in the first-grade students. In the smoking rate, there was lower in the third-grade students than in the first-grade students. The rate of acknowledging smoking hazard to the periodontal health was higher in the third-grade students than in the first-grade students. Conclusions : This study revealed that the third-grade students of dental hygiene departments who were majoring in dental hygiene had a higher perception of oral health than the first-grade students whose the dental hygiene education period was short.
