This study compares AI PengTalk’s assessments of Korean children’s pronunciation with the assessments of Korean teachers. Sixty Korean sixth-graders participated as assessees, and four Korean elementary teachers participated as assessors. Both PengTalk and the teachers rated the children’s production of 10 English sentences on a five-point scale. They focused on segmentals, stress-rhythm, intonation, and speech rate. The findings were as follows: Firstly, PengTalk evaluated the children’s pronunciation in the four elements significantly lower than the teachers across all English proficiency levels. Secondly, teachers’ ratings of the students aligned more closely with their pre-evaluated English proficiency levels than the AI PengTalk’s assessments. The teachers rated students at the upper level significantly higher than those at the intermediate level, who were, in turn, assessed significantly higher than those at the lower level in all four elements. Furthermore, AI PengTalk and the teachers differed in the mean order of the four elements, particularly in segmentals. Based on the results of this study, suggestions were made for the development and implementation of AI-based English programs.

Purpose: This study aimed to investigate the readiness for interprofessional education and educational needs, develop a pediatric nursing clinical practicum program for interprofessional education, and evaluate its effectiveness. Methods: A survey of total 272 undergraduate nursing students and medical students and a focus group interview were used to explore the need of interprofessional education. An interprofessional pediatric nursing practicum program was developed. The program consisted of three sessions: orientation and ice break (1 h), holo-patient assessment (1 h), and 5 twins team-based learning (2 h). Effectiveness was evaluated among nine nursing and medical students. Data were analyzed by descriptive statistics, the independent t-test, and the Wilcoxon rank-sum paired t-test. Results: The scores of readiness for interprofessional learning in nursing students were significantly higher than those in medical students. And the scores significantly increased after participating in the program (Z=-2.81, p=.005). The overall satisfaction with the program was 4.33 out of 5 points. Conclusion: The interprofessional education program had a positive effect on the readiness for interprofessional learning. This program can have a positive impact on patient safety and quality of care and can contribute to the expansion of nursing education through various teaching methods.

Assessment of noise exposed population is to check the environment noise level and social influence in order to reduce the risks such as annoyance and disturbance that are generated by environmental noise. Also, this method suggests the preferential noise abatement policy and action plan by accurately finding the area that the noise causes harmful effect to human health. Recently, a noise map, which can predict noise in comprehensive area, is used for the assessment of noise exposed population, breaking from the methods using existing measures. In particular, countermeasure for noise can be considered more effectively by using assessment methods of noise exposed population for specific noise level, area and building types which are the main input factors in noise maps. In this study, we propose noise prediction at traffic noise due to noise map.

The aim of this study was to develop and evaluate a nutrition education program that was designed to increase the knowledge, attitudes, and skills of Korean adults regarding nutrition labeling. The education program was 45 minutes of short-term training, which was conducted in the form of lectures and exercises. The contents of the program were as follows: in the introduction stage, talking about status and reasons for checking nutrition labels; in the development stage, explanation of nutrition labeling and their content, reading, and identifying sample nutrition labels, as well as comparing nutrition labels and selecting better foods; in the closing stage, summary of nutrition labeling and a pledge to check nutrition labels when purchasing processed food. A total of 53 adults (88.5% female) aged 30 years and over participated in this study. The nutrition labeling awareness of the subjects was increased significantly from 55.8 to 96.2% after the education. After the education, the correct recognition rate of a nutrition label was increased significantly from 26.9 to 78.8% for the amount of food, from 25.0 to 73.1% for the calorie content, from 36.5 to 69.2% for the nutrient contents, and from 30.8 to 82.7% for the percent daily value. The self-efficacy of checking nutrition labels was also increased significantly compared to that before the education. The overall satisfaction score of the nutrition education program was 4.2 out of 5. The outcome showed that the nutrition education program of nutrition labeling improved the participants’ awareness and self-efficacy towards checking nutrition labels.

This study aimed to develop and evaluate a sugars intake reduction program (SIRP) that was designed to increase the knowledge, attitude, and skills of Korean children aged 5 years regarding sugars intake reduction. A total of 101 children aged 5~6 years from 6 preschools participated in SIRP. SIRP consisted of 4 sessions including 10 activities (e.g., story-telling, arts, experiment, checking nutrition facts, pledge), delivered to children at preschools by nutritionists over a one-month period. Three letters were sent to parents throughout the program to inform them of the children’s activities at the preschools and to provide additional information on reducing children’s sugars intake. A total of 90 children completed the program; 83 parents of these children completed the SIRP evaluation survey. The children’s sugars intake reduction score was significantly increased after attending SIRP. Teachers (n=6) who participated in this program agreed to improve their students’ attitudes on reducing sugars intake and to decrease students’ behaviors related to sugars intake. Parents agreed to improve their children’s attitude on reducing sugars intake and to decrease children’s behaviors related to sugars intake. The outcome showed SIRP improved participants’ attitudes towards sugars reduction and increased the skills to reduce the sugars intake of children aged 5~6 years. Future studies should examine whether SIRP reduces actual sugars intake among children.

최근 서울 도심 지역에 급격한 자동차 수 증가로 인한 도로교통소음의 심각성이 사회에서 주목을 받고 있다. 각 기관들은 도로교통소음을 해결하기 위해 여러 가지 방안을 내놓고 있으며, 2017년 3월 서울시는 저소음포장을 소음감소대책으로 내놓았다. 여러 가지 소음감소대책 중 저소음포장이 최근 들어 많은 관심을 받고 있는 이유는 방음벽과 방음터널의 경우 도심의 미관을 파괴하고 소음대책이 필요한 지점에 따라 소음저감 효과가 상이하게 발생하는 반면, 저소음포장의 경우 소음대책이 필요한 지점에 상관없이 일정한 소음저감 효과를 나타내고 있기 때문이다. 이와 관련하여 본 연구에서는 소음예측 프로그램을 통하여 저소음포장의 소음감소효과를 평가를 하는 것을 목적을 두고 있다. 소음예측은 Korea Environment Institute 가이드라인에 기초하여 수행되었다. 저소음 포장에 대한 감소효과를 평가하기 위해 소음지도 모델링을 진행하여야 한다. 모델링의 경우 일반포장에서의 실제 교통량과 통행속도를 입력하여 나온 시뮬레이션 값과 실제 지점에서 소음을 측정한 값이 3dB차이가 나지 않아야 검증된 모델로 규정하고 있다. 이렇게 검증이 된 모델을 사용하여 소음예측을 진행하였을 때, 일반 포장이 설치 된 도로를 저소음포장으로 교체 설치하여 소음감소도를 분석하게 된다. 또한 저소음포장이 한 층 및 두 층으로 포장되었을 경우에 대해 소음감소도를 분석하였고, 여러 조건의 속도와 교통량을 입력하여 각 조건별로 감소도를 분석하였다. 여러 가지 상황에서 어떤 경우에 가장 많은 감소도를 보이는지 분석하였다. 그림 1.은 특정 교통량과 특정 속도에 대한 소음예측을 한 것이다. 그림 2.의 경우는 그림 1.과 같은 교통량과 속력을 입력하였지만 포장이 저소음포장을 두 층으로 바꿔 설치 된 것이다. 그림을 비교해보면 저소음포장을 설치한 경우 7dB의 감소도를 볼 수 있다. 이를 포함한 많은 경우의 수에서 저소음포장에 대한 소음감소도를 분석하였다

This study developed a vegetable preference increase program that can be applied at the Center for Children's Foodservice Management (CCFM) for children in child-care facilities and kindergarten and the training performance was evaluated by 192 5-year old children. Teachers considered ‘disliked food’ (3.23±0.85/out of 5) as the most serious nutritional problem and typical disliked food was ‘vegetables’ (54.2%). Based on this finding, to increase the preference for vegetables, a fivephase education program was developed. In this program, each phase was composed of activities to increase children's interest in vegetables by using each sense out of the five senses. Center dieticians had visited and conducted the program in 12 facilities. By using an illustration assessment tool, the training performance was evaluated by comparing the children's knowledge level and their preference changes in vegetables. Consequently, as examined by 10 questions on the knowledge of vegetables, trained children's (in total 192) knowledge of vegetables had considerably increased (p<0.01, p<0.001), and their preference for 15 out of the 16 vegetables, except for carrots, also showed a considerable preference increase after the training (p<0.01, p<0.001). Therefore, this program is considered to have contributed to reducing disliked vegetable eating behaviors.
