This paper proposes the basic analytical framework of web development systems from the perspective of system dynamics. Based on the feedback characteristic of web development activities, we analyze the causality in the web development from six aspects including work stress, web development, motivation, developer maintenance, recruitment and outsourcing and create a casual loop diagram of web development. Through system analysis, crucial factors needed for web developers to accomplish web development tasks continuously and stably are illuminated. The results show that external variables such as new recruitment and case outsourcing can have a short-term effect on the system, while internal variables such as work motivation and work stress have a greater influence on web development activities, which will result in a fluctuation of job performance. From the perspective of management, countermeasures are put forward on how to mobilize the enthusiasm and initiative of developers and improve productivity.

Purpose: Since anticancer medication nursing is an evaluation area for accreditation by medical institutions in Korea, all clinical nurses are required to attend an annual classroom lecture. However, it is necessary to reconsider the methods and effects of this requirement. This study was conducted to develop a web-based anticancer chemotherapy nursing course for clinical nurses and to examine its effectiveness in terms of job knowledge, self-efficacy, and nursing performance. Methods: A randomized controlled design using random selection was utilized. The content was developed into 5 modules featuring basic and advanced learning, and the total learning time was 80 minutes. To test the effect of the multimedia contents, a randomized control group pretest-posttest study design was adopted. Clinical nurses with less than five years of experience were recruited from a university-affiliated hospital and randomly assigned to an experimental (n=28) or control (n=28) group. The experimental group autonomously learned web-based anticancer chemotherapy nursing for two weeks through a website. Results: There was a statistically significant increase in the job knowledge of the experimental group receiving the classroom lecture (p=.001). However, there were no statistically significant differences between the two groups in self-efficacy (p=.055) and nursing performance (p=.359). Conclusion: This study found that web-based self-learning could be a useful learning strategy for the anticancer chemotherapy and nursing education that clinical nurses must complete annually. However, it is necessary to verify the effect on self-efficacy and nursing performance through repeated studies.

Purpose: This study aimed to develop a mobile web-based food allergy (FA) and anaphylaxis management educational program for parents of school-aged children with food allergies and evaluate its effectiveness. Methods: A mobile program was developed based on a web-based teaching-learning system model. Its effectiveness was subsequently evaluated using a parallel, randomized controlled pre- and post-test design. This study included 73 parents of school-aged children with food allergies. These parents were randomly assigned to either the experimental (n ¼ 37) or control (n ¼ 36) groups. The experimental group participated in a 2-week mobile web-based educational program that covered major topics in FA and anaphylaxis management. These topics included an understanding of food allergies and anaphylaxis, learning techniques for using an epinephrine auto-injector, and developing an emergency action plan. An educational booklet was provided to the control group. Participants completed a pre-test and two posttest questionnaires to evaluate the impact of the program. The assessment tools were the Food Allergy Knowledge Test, Food Allergy Self-Efficacy for Parents, and Food Management and Adaptation Scale. The data were analyzed using descriptive statistics, a test of homogeneity for the pre-test, an independent ttest, and repeated measures ANOVA. Results: The experimental group experienced greater improvement in the knowledge of FA (postintervention t ¼ 14.51, p < .001; 2 weeks post-intervention, t ¼ 16.15, p < .001), FA self-efficacy (postintervention t ¼ 77.99, p < .001; 2 weeks post-intervention, t ¼ 76.09, p < .001), and practice behavior in FA management (post-intervention t ¼ 28.10, p < .001; 2 weeks post-intervention, t ¼ 27.98, p < .001) after web-based FA education. Conclusion: This study revealed improvements in the knowledge, self-efficacy, and practice behaviors of parents regarding FA and anaphylaxis management. Therefore, the mobile web-based educational program can contribute to the effective management of food allergies and anaphylaxis for parents of schoolaged children. CRIS registration: KCT0007491.

4차 산업혁명의 기술 발전에 따라 학교에서의 교육환경도 점점 스마트하게 변하고 있다. 교육을 위한 장비들도 보다 첨단화되고 있으며, 이로 인해 전자칠판이 교실환경에 보편화되고 있다. 그러나 지금의 전자칠판은 터치가 되는 장 비에 판서 소프트웨어가 포함되어 배포되고 있기 때문에, 판서 작업을 수행하기 위해서는 소프트웨어가 탑재된 장비 가 필요하다. 또한 판서 소프트웨어의 기능이 수정, 변경될 경우 각 장비마다 일일이 소프트웨어를 재 설치하거나 업데이트를 수행해야 한다. 본 논문에서는 전자칠판 장비의 독립성을 향상시키기 위하여 웹기반 판서 소프트웨어의 개발 내용에 대해 기술한다. 웹기반의 판서 소프트웨어는 터치로 입력이 가능하고 인터넷이 되는 모든 장비에서 웹 을 통해 판서 기능을 사용할 수 있게 함으로써 장비 독립성 통해 소프트웨어 유지보수 비용을 줄이고 사용 접근성을 높여준다.

According to development of the 4th Industrial Revolution technology, the educational environment in schools is gradually changing digital-smart and high-tech. At this time, electronic board system has come into wide use in school. However, since today’s electronic board system is distributed by including the writing software in the touching equipment, the equipment with built-in software is needed to write on the board. In addition, if the functions of the software are modified or changed, the software of each device must be reinstalled or updated. In this paper, we describe the development of web-based writing software to improve the independence of electronic board equipment. Because the web-based writing software can be used through the web on all the Internet and touch-typing enabled devices, the equipment independence reduces software maintenance costs and improves accessibility.

This study introduces the web-camera image processing-based natural landmark extraction method for automatic welding using 3-axis stage. The welding is a highly significant process in the industries of shipbuilding, automobile, construction, machinery, and so on. However, it has been avoided due to poor working conditions such as fume, spatter, noise, and so on. For the automatic welding system, the web-camera is used to extract the natural landmarks which can give the relative coordinate to set up the initial position of the stage for the welding process. The Canny edge and Hough transformation have been used to extract the significant points for the natural landmark extraction in this paper.
