  • Purpose: This study was conducted to investigate the effects of core basic nursing education using cellular phone video recordings on self-confidence in performance, achievement, and practice satisfaction. Methods: The research design was a nonequivalent control group modified and non-synchronized design. The participants were assigned to either the experimental (n=60) or control group (n=67). During one semester, the experimental group received training for 10 selected core basic nursing skills using cellular phone video recording. The control group, also for one semester, received training with traditional practices. Self-confidence in performance and practice satisfaction were measured using a questionnaire, and achievement was evaluated by professors at the conclusion of the semester. Collected data were analyzed using t-test and Pearson correlation coefficients. Results: Self-confidence in performance increased significantly after training in the experimental group (t=7.94, p<.001). The experimental group showed significantly higher self-confidence in performance (t=2.39, p=.018) and achievement (t=2.40, p=.018) compared to the control group. However, the difference in practice satisfaction was not statistically significant. Conclusion: The results indicate that cellular phone video recording is effective in improving self-confidence in performance and achievement of core basic nursing skills.

  • Background: Because a forward-leaning posture can cause increased back muscle activity and pain. Therefore, an innovative method to reduce back muscle activity and pain is required. Objects: This study aimed to investigate the effects of a head support on muscle activity and pain in a forward-leaning posture. Methods: A total of 14 male and 16 female students (average age, 21.65 ± 2.37 years; height, 166.15 ± 7.90 cm; and weight, 60.65 ± 9.00 kg) were recruited for the experiment. Two of them were excluded due to musculoskeletal disorders. The muscle activity and pain in the forward-leaning posture were assessed while participants washed dishes for 7 minutes with and without a head support. The condition of using a head support was randomly performed with a 5-minutes break. To confirm a lumbar flexion angle of 30° during the experiment, myoVIDEO was used, and surface electromyography was used to measure muscle activity. Pain was assessed using a 10-point visual analog scale (VAS). The Wilcoxon signed-rank test was used to analyze the data, with p < 0.05 indicating statistical significance. Results: The cervical, thoracic, and lumbar erector spinae muscle activities significantly decreased with the use of the head support, but there was no significant change in the gluteus maximus. There was a significant decrease in the VAS score for the lumbar erector spinae (p < 0.05), but there was no significant change in the VAS score for the cervical region. Conclusion: The use of a head support in a forward-leaning posture reduced cervical, thoracic, and lumbar erector muscle activity and pain. Therefore, it could be recommended during working in a forward-leaning posture, such as during dishwashing, cooking, and working as a factory employee.

  • 뇌경색, 뇌 신경장애 및 뇌졸중환자 중 급성기 환자는 의식이 없어 연하기능장애로 인한 흡인성 폐렴을 유발하기 때문에 비위관(nasogastric tube)을 삽입하고 영양공급을 한다. 재활훈련 후 회복기에 침상선별검사를 시행하지만 임상적 검사를 통해서는 무증상흡인은 발견할 수 없다. 그래서 연하장애로 비위관을 삽입한 연하재활치료 중인 환자 10명을 대상으로 VFSS를 시행하여 식이재료에 따른 삼킴 정도, 자세에 따른 삼킴을 재활의학과전문의가 평가 후, 흡인이 있거나 삼킴 곤란 등이 있으면 연하재활치료를 시행하여 환자의 상태에 따라 약 30일 ~ 50일후에 재평가를 시행한 후 흡인이 없을 시 비위관을 제거 하였다. 이때 VFSS 영상을 기능적 연하곤란척도를 이용, 분석하여 부여된 점수를 통계 산출 하였는데 비위관 유지군은 $49.79{\pm}9.431$을 보여 흡인의 위험을 나타내며, 비위관 제거군은 $11.20{\pm}1.932$로 흡인의 위험성이 낮아 비위관 제거관련 의미 있게 낮은 점수를 보였다. 두 군의 유의성을 평가하기 위해 Mann-Whitney test를 시행한 결과 p<0.001로 통계적으로 유의하다고 평가하였다. 결론적으로 VFSS는 구강, 인두, 식도의 구조적 이상과 움직임을 가장 효과적으로 평가, 기도흡인여부를 즉시 확인 및 환자에게 적합한 식이나 연하자세를 결정할 수 있어 비위관 제거를 위한 연하평가에 가장 확실한 표준검사로 제안할 수 있다.

  • The multi-band and wide-band antenna for a portable broadcasting terminal is proposed. The proposed antenna consists of two radiators with a parallel structure. The antenna has an enough wide impedance bandwidth for the DVB-H(Digital Video Broadcasting-Handheld) service band since two radiators have adjacent resonance frequencies and operates in the DAB(Digital Audio Broadcasting) service band using the third harmonic of the radiator 1. The fabricated antenna has VSWR characteristics of less than 2:1 in the frequency band $470{\sim}740\;MHz$ for DVB-H and $1,450{\sim}1,480\;MHz$ for DAB. The measured peak gain of the antenna is $1.97{\sim}4.10\;dBi$ in the DVB-H band and $1.98{\sim}2.04\;dBi$ in the DAB band.
