Objectives: This study aimed to develop a school-centered healthy eating environment for children in elementary care classrooms and prevent incorrect eating habits and obesity through the development and application of standardized healthy eating habit-forming educational materials. Methods: Ten schools in eight districts of Gyeonggi-do and 400 students from 19 care classes were selected. Based on the developed educational materials, the program was applied to students once in two weeks. 'Notices for Parents' forms were also sent to the students' home to educate their parents. Pre and post-surveys were conducted to evaluate the effectiveness of the education. The pre-education, education, and aftercare were conducted from September 28 to September 31, 2016, from October 3 to November 30, 2016, and from December 5 to December 9, 2016, respectively. Results: The healthy eating program for elementary care classes was designed to develop a school-centered healthy eating environment and provide standardized educational material for healthy eating habits. Twelve educational topics were developed: , , , , , , , , , , , and . Moreover, the materials were produced in four forms: for students, for after school caring teachers, for external specialists, and for parents. The effectiveness evaluation was conducted to confirm the application of the program. The average eating habits score was 3.3 ± 0.6, with no significant difference between before and after application. The score of overall satisfaction of the education was 3.9 ± 0.9. The most satisfying content was 'Did you get to know how to eat evenly?'. Significant increases were observed in two contents for parents regarding their children's knowledge changes after the education: 'Five nutrients needed for growing children' and 'Knowing sugar foods and sugar-containing foods'. On the other hand, their educational satisfaction was 3.6 ± 0.6, which was lower than the children's satisfaction. This might be because their education was conducted only through the 'Notices for Parents' form. Conclusions: In the long term, the healthy eating habit-formation education for lower elementary school children is expected to be beneficial. To prevent obesity and establish healthy eating habits of children, it is important to develop healthy eating education programs centered on elementary school aftercare classes, including the development of educational materials and an application system through connection with the home and community.

Workflow Management System (WFMS) is a software system to support an efficient execution, control and management of complex business processes. Since traditional commercial systems mainly focus on automating processes, they don't have methods for enhancing the task performer's efficiency. In this paper, we propose a new method of executing business processes more efficiently in that a whole process is scheduled considering the degree of the participants' workload. The method allows managing the largest constraints among constituent resources of the process. We utilize DBR scheduling techniques to develop the method. We first consider the differences between workflow process models and DBR application models, and then develop the modified drum, buffer and rope. This leads us to develop WF-DBR (WorkFlow-DBR) that can control the proper size of the task performers' work list and arrival rate of process instances. Use of WF-DBR improves the efficiency of the whole process as well as the participants' working condition. We then carry out a set of simulation experiments and compare the effectiveness of our approach with that of scheduling techniques used in existing systems.

Since real road experiments have many restrictions, a multi-vehicle traffic simulator can be an effective tool to develop and evaluate fully automated driving systems. This paper presents multi-vehicle environment simulation tool to develop and evaluate motorway automated driving systems. The proposed simulation tool consists of following two main parts: surrounding vehicle model and environment sensor model. The surrounding vehicle model is designed to quickly generate rational complex traffic situations of motorway. The environment sensor model depicts uncertainty of environment sensor. As a result, various traffic situations with uncertainty of environment sensor can be proposed by the multi-vehicle environment simulation tool. An application to automated driving system has been conducted. A lane changing algorithm is evaluated by performance indexes from the multi-vehicle environment simulation tool.

Purpose: This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. Methods: A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, ${\chi}^2$-test, t-test, and ANCOVA with the SPSS 18.0. Results: The experimental group showed more 'self-efficacy for drug dosage calculation' than the control group (t=3.82, p<.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p<.001), with regard to 'metric conversion' (t=2.25, p =.027), 'table dosage calculation' (t=2.20, p =.031) and 'drop rate calculation' (t=4.60, p<.001). There was no difference in improvement in 'anxiety for drug dosage calculation'. Mean satisfaction score for the program was 86.1. Conclusion: These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.
