Purpose: The purpose of this study is to investigate new nurses' needs for intravenous infusion therapy training by analyzing the current training status. Methods: This study examined the needs for intravenous infusion therapy training with 159 new nurses. The measurement tool consisted of 93 items developed based on intravenous therapy-related studies, and was evaluated on a 4-point Likert scale. For data analysis, SPSS/WIN 25.0 was used, and frequency, percentage, average, standard deviation, paired t-test, were performed. Results: The demand for intravenous therapy education was analyzed using a questionnaire composed of 8 areas, 16 sub-areas, and 93 items. According to the findings, post-ward placement intravenous therapy education(83.7%) is conducted more often than in preliminary education (72.2%). The demand for intravenous infusion therapy education did not differ significantly in preliminary and post-ward placement education (t=-.89, p=.376). While therapy skills were preferred in preliminary education, there were high demands for education content related to blood transfusion, central venous catheter, and drug use in continuing education. As for preferred teaching methods, lecture (38.2%) and simulation (26.7%) were most answered for preliminary education, while a range of methods were preferred for continuing education including lecture (31.1%), clinical practice (20.6%), preceptor training (19.8%), simulation (16.8%), and self-study (11.6%). Conclusion: For efficient training, it is required to provide different education contents and methods for each stage.

Sabah has experienced a rapid decline in the extent of forest cover. The precise impact of habitat loss on the conservation status of the plants of Sabah is uncertain. In this study we use the niche modelling algorithm MAXENT to construct preliminary, revised and final ecological niche models for Dipterocarpus lamellatus and Dipterocarpus ochraceus and combined these models with data on current land-use to derive conservation assessments for each species. Preliminary models were based on herbarium data alone. Ground surveys were conducted to evaluate the performance of these preliminary models, and a revised niche model was generated from the combined herbarium and ground survey data. The final model was obtained by constraining the predictions of the revised models by filters. The range overlap between the preliminary and revised models was 0.47 for D. lamellatus and 0.39 for D. ochraceus, suggesting poor agreement between them. There was substantial variation in estimates of habitat loss for D. ochraceus, among the preliminary, revised and constrained models, and this has the potential to lead to incorrect threat assessments. From these estimates of habitat loss, the historic distribution and estimates of population size we determine that both species should be classified as Critically Endangered under IUCN Red List guidelines. Our results suggest that ground-truthing of ecological niche models is essential, especially if the models are being used for conservation decision making.

Software Education will be implemented at elementary, middle and high schools starting in 2018. The goal of software education is to help students develop Computational thinking skills. Especially, using robots in software education increases student interest and helps to increase creativity. In order for software education using robots to be effective, education for teachers should be effective. The development of effective education contents for preliminary teachers can be said to be the success of software education. By the way, effective education can be said to begin with an accurate analysis of the subjects. In order to develop an effective curriculum for preliminary teachers, it is necessary to grasp the level of preliminary teachers who will carry out the software education using robots. Therefore, in this paper, we surveyed the experiences, levels and perceptions of preliminary teachers to help develop software education curriculum using robots.

The purpose of this study was to develope, based on the Nursing Intervention Classification (NIC) system. a set of standardized nursing interventions which had been validated. and their associated activities. for use with nursing diagnoses related to home health care for women who have had a caesarian delivery and for their newborn babies. This descriptive study for instrument development had three phases: first. selection of nursing diagnoses. second, validation of the preliminary home health care interventions. and third, application of the home care interventions. In the first phases, diagnoses from 30 nursing records of clients of the home health care agency at P. medical center who were seen between April 21 and July 30. 1998. and from 5 textbooks were examined. Ten nursing diagnoses were selected through a comparison with the NANDA (North American Nursing Diagnosis Association) classification In the second phase. using the selected diagnoses. the nursing interventions were defined from the diagnoses-intervention linkage lists along with associated activities for each intervention list in NIC. To develope the preliminary interventions five-rounds of expertise tests were done. During the first four rounds. 5 experts in clinical nursing participated. and for the final content validity test of the preliminary interventions. 13 experts participated using the Fehring's Delphi technique. The expert group evaluated and defined the set of preliminary nursing interventions. In the third phases, clinical tests were held at in a home health care setting with two home health care nurses using the preliminary intervention list as a questionnaire. Thirty clients referred to the home health care agency at P. medical center between October 1998 and March 1999 were the subjects for this phase. Each of the activities were tested using dichotomous question method. The results of the study are as follows: 1. For the ten nursing diagnoses. 63 appropriate interventions were selected from 369 diagnoses interventions links in NlC., and from 1.465 associated nursing activities. From the 63 interventions. the nurses expert group developed 18 interventions and 258 activities as the preliminary intervention list through a five-round validity test 2. For the fifth content validity test using Fehring's model for determining lCV (Intervention Content Validity), a five point Likert scale was used with values converted to weights as follows: 1=0.0. 2=0.25. 3=0.50. 4=0.75. 5=1.0. Activities of less than O.50 were to be deleted. The range of ICV scores for the nursing diagnoses was 0.95-0.66. for the nursing interventions. 0.98-0.77 and for the nursing activities, 0.95-0.85. By Fehring's method. all of these were included in the preliminary intervention list. 3. Using a questionnaire format for the preliminary intervention list. clinical application tests were done. To define nursing diagnoses. home health care nurses applied each nursing diagnoses to every client. and it was found that 13 were most frequently used of 400 times diagnoses were used. Therefore. 13 nursing diagnoses were defined as validated nursing diagnoses. Ten were the same as from the nursing records and textbooks and three were new from the clinical application. The final list included 'Anxiety', 'Aspiration. risk for'. 'Infant behavior, potential for enhanced, organized'. 'Infant feeding pattern. ineffective'. 'Infection'. 'Knowledge deficit'. 'Nutrition, less than body requirements. altered', 'Pain'. 'Parenting'. 'Skin integrity. risk for. impared' and 'Risk for activity intolerance'. 'Self-esteem disturbance', 'Sleep pattern disturbance' 4. In all. there were 19 interventions. 18 preliminary nursing interventions and one more intervention added from the clinical setting. 'Body image enhancement'. For 265 associated nursing activities. clinical application tests were also done. The intervention rate of 19 interventions was from 81.6% to 100%, so all 19 interventions were in c1uded in the validated intervention set. From the 265 nursing activities. 261(98.5%) were accepted and four activities were deleted. those with an implimentation rate of less than 50%. 5. In conclusion. 13 diagnoses. 19 interventions and 261 activities were validated for the final validated nursing intervention set.

Software education will be implemented in elementary schools in Korea since 2019. Although 17 hours of software education is provided, it is necessary for preliminary teachers to have basic ICT skills in training software education. Therefore, it is necessary to objectively compare the basic ICT literacy of preliminary teachers in Korea. This study examines the ICT of preliminary teachers based on the OECD PISA 2015 questionnaires. The contents of the survey compares and analyzes ICT availability and usability items of students. Comparisons are made with students from OECD countries. ICT usability at school was the highest at 2.56, followed by ICT availability at school at 2.4. The third was high at 2.38 for using school works outside the school. Availability outside the school was low at 2.33, and the lowest at school was very low at 1.79. It is necessary for the preliminary teachers to have the ICT ability for the students who will be the protagonists of the future society and the ICT education which can be utilized in each subject in addition to the ICT education in the curriculum of the education college in order to raise the ability.

Purpose: This study was conducted to develop a teacher-efficacy scale which is adequate for heath education teachers. Method: A preliminary questionnaire was made based on the hypothetical factors. A total of 364 health education teachers answered to the preliminary test, and the potential factors of teacher-efficacy were checked out by exploratory factor analysis (EFA). In the main test 378 health education teachers answered, the factor structure was drawn by EFA, and confirmatory factor analysis (CFA) was conducted to test and the fitness of the factor model. Results: Through the preliminary test, 5 potential factors were found, which were instruction, health-service, administrative task, interpersonal relationship, and community connection. Also, 48 items were reduced to 31 items. Through the main test, from the 34 items were extracted 4 factors with 24 items, And then teacher-efficacy scale was developed, which included the subscales of instruction efficacy, health-service efficacy, task-interpersonal efficacy, and community connection efficacy. Conclusion: Different from that for other subject teachers, the factor structure for health teachers had 4 factors with 24 items. The scale developed in this study is consistent with health teachers' work areas, and for this reason, has significance as a adequate and valid scale to measure teacher-efficacy of health education teachers.
