Objectives: This study was conducted to examine the effects of digital empowerment teacher training program applying virtual reality on digital media literacy, teacher efficacy, and problem-solving ability of school nurse. Methods: A quasi -experimental study of pre- and post-experimental design was performed on 47 school nurse located in K city and the developed digital empowerment teacher training program was implemented. The data collection period is July 27, 2021, and the collected data is collected using the SPSS 18.0 program. Paired t-test were analyzed. Results: According to the results of the effect, it was found that there was a significant difference in digital media literacy and problem-solving ability. Conclusions: The digital empower ment teacher training program developed in this study can be used as an effective program to enhance the digital media literacy and problem-solving ability of school nurse.

N/A Objective:Our goal was to evaluate the clinical characteristics and statistical analysis in incompetent internal os of the cervix(IIOC) Method: At Department of Obstetrics and Gynecology, Eulgi Hospital and Eulgi university Hospital from January 1, 1991 to December 31, 1997, 296 cases of IIOC were admitted and treated with McDonald operation or modified Shirodkar operation. Of this, 38cases were follow up lost, so 252 cases were analayzed. Diagnostic criteria was previous history of painless cervical dilatation, followed by spontaneous abortion or preterm birth, and acceptance without resistance at the internal os of No. 8 Hegar dilator. Result: Incidence of IIOC was 1.61%, 1 in 60 deliveries. Most frequent age group was in 28-30 years old group and mean age was 30 years old. Total number and mean number of gravida was 818 and 3.2. The most common contributing factor was previous artificial abortion(77%), and cervix dilatation(9%), old cervical laceration(4.3%) etc, was followed. Operation methods were McDonald operation(56%) and modified Shirodkar operation(44%). The Success rate of McDonald and modified Shirodkar was 78.1% and 88.1%. Successful fetal salvage rate was 82.5%, and the highest success rate was 86.9% in 14-18th weeks of gestation group. The more cervix dilate, the more failure occured. Causes of operation failure was premature rupture of membrane(54.5%), preterm labor(43.2%) and fetal death in utero(2.3%). Delivery method after operation was vaginal delivery(146cases, 70.9%) and cesarean delivery(60cases, 29.1%). Cause of cesarean delivery was previous cesarean section(43.3%), breech presentation(16.7%), cephalopelvic disproportion(15%), prolonged labor(6.7%), fetal disttess(6.7%), twin(5%), placenta previa(3,3%) and abruptio placenta(3.3%). Conclusion: The 14-18th weeks of gestation group & no cervical dilatation group has higher success rate, which indicate early diagnosis and appropriate timing of operation is probably associated with a greater operation

For each construction material used, there is certain theoretical limit in sizes.For tall building construction, the reduction in slab weight is the first step to take in order to break such size limits.In this paper, the feasibility of such objective is proven and given by numerical analysis result.For a typical building slab, both concrete and advanced composite sandwich panels are considered.The concrete slab is treated as a special orthotropic plate to obtain more accurate result.For each panel, the deflection under the dead and live loads is compared, since both tensile and compressive strengths of the composites are far more higher than those of concrete.All types of sandwich panels considered, except one case, have weights less than one tenth of that of reinforced concrete slab, with deflections less than that of the concrete slab.
