The purpose of this survey was to investigate the food behavior and vegetable preferences of elementary school students in the metropolitan areas of, South Korea. Five hundred and eighty students (277 male and 303 female) studying in grades 5~6 participated in the survey. We assessed food behavior by evauating the Nutrition Quotient (NQ). Through a questionnaire, which consisted of 20 food behavior checklist items. These items were grouped under five factors: balance, diversity, moderation, practice and environment. All data were analyzed using SPSS 25.0. The average NQ score weighted using the five factors was 61.32 points. Among the five factors, moderation showed the lowest score, whereas environment showed the highest score. The average score of the vegetable preference was 3.36 points out of a total of 5 points. The vegetable preference was found to be highest for bean sprouts and followed by tomatoes, lettuce, spinach, Chinese cabbage, sesame leaf, pumpkin, carrot, radish, chives, lotus roots, onions, broccoli, sweet peppers, and eggplant. The results of vegetable preferences by NQ grade were 4.13±0.63 points for the high grade, 3.68±0.75 points for the medium-high grade, 3.41±0.82 points for the medium-low grade, and 2.94±0.78 points for the low grade. There was a significant positive correlation between NQ and vegetable preferences (r=0.477, P<0.001). If vegetables with high preference are frequently provided in school meals, it might contribute to improving overall food behavior.

This study suggests a design of predictive modeling for a hospital fall risk based on inpatients' posture. Inpatient's profile, medical history, and body measurement data along with basic information about a bed they use, were used to predict a fall risk and suggest an algorithm to determine the level of risk. Fall risk prediction is largely divided into two parts: a real-time fall risk evaluation and a qualitative fall risk exposure assessment, which is mostly based on the inpatient's profile. The former is carried out by recognizing an inpatient's posture in bed and extracting rule-based information to measure fall risk while the latter is conducted by medical staff who examines an inpatient's health status related to hospital fall risk and assesses the level of risk exposure. The inpatient fall risk is determined using a sigmoid function with recognized inpatient posture information, body measurement data and qualitative risk assessment results combined. The procedure and prediction model suggested in this study is expected to significantly contribute to tailored services for inpatients and help ensure hospital fall prevention and inpatient safety.

This study attempted to analyze the jobs of early childhood special education teachers working in kindergarten's special classes using the DACUM technique. To this end, the DACUM Committee was formed with six early childhood special education teachers with extensive field experience. A total of six DACUM workshops were conducted to derive job definition, job descriptions, and job specifications. As a result, the job description of early childhood special education teachers consisted of 9 duties and 53 tasks, and the job specification consisted of 80 knowledge, 98 skills, and 22 attitudes. Early childhood special education teachers working in kindergarten's special classes were tasks differentiated from special education teachers working in elementary and secondary school including home-linked guidance, health and safety management, elementary school transfer guidance, environmental composition according to play topics, and indoor and outdoor play activities guidance. In the case of knowledge, the Special Education Act on the Disabled, etc. and knowledge on behavioral modification took precedence. Skill showed high frequency of observation-record, parental interviews and parental education skills. Attitudes as experts and administrators took priority. The results of this job analysis can help organize a curriculum to train early childhood special education teachers with high job competency in universities.

The construction is the industry with the highest fatalities, and the fatalities has not decreased despite various institutional improvements. Accordingly, real-time safety management by applying artificial intelligence (AI) to CCTV images is emerging. Although some research on worker detection by applying AI to images of construction sites is being conducted, there are limitations in performance expression due to problems such as complex background due to the nature of the construction industry. In this study, the YOLO model and the OpenPose model were fused to improve the performance of worker detection and posture estimation to improve the detection performance of workers in various complex conditions. This is expected to be highly useful in terms of unsafe behavior and health management of workers in the future.
