Purpose: The purpose of this study was to develop content for safety education to prevent hospital safety accidents among hospitalized children and to investigate the status of safety education performed by nurses. Methods: First, the Delphi method was used, with 18 experts, to develop educational contents for preventing safety accidents. Second, an exploratory survey was performed of the actual status of safety education for preventing safety accidents among hospitalized children using a questionnaire developed based on the Delphi method. The participants of this study were 159 nurses with at least 6 months of work experience. Results: The educational content developed through the Delphi method for preventing safety accidents among hospitalized children contained seven domains (falls, injury, electric shocks/burns, suffocation/aspiration, poisoning/abuse, kidnapping, medical devices) with 44 topics. The item mean of nurses'perceptions of the importance of child safety education was 4.18, and the actual performance score was 3.72, which was a statistically significant difference (t=11.58, p<.001). Conclusion: These seven comprehensive domains of accident prevention education for hospitalized children are expected to be useful for interventions to support the safety of hospitalized children.

Existing safety education delivered to construction workers has limitations in concentration and immersion, so delivery power and interest are low. In order to improve the unstable behavior of construction workers and prevent safety accidents through education, a paradigm shift to hands-on education is necessary. Experiential safety education aims to contribute to the prevention of safety accidents and induce safe behavior by construction workers to recognize risks faster, select safe working methods suitable for the working environment, and improve emergency response and proactive response. Experiential education facilities have a follow-up learning effect in case of danger. The experience facility, which consists of the same working environment as the actual construction site, is designed to experience falls, equipment contraction, fire, and electric shock. In order to achieve the results of safety education that has invested a lot of time, construction workers must have motivation to participate, and "experiential safety education" through playful, deviant, and aesthetic experiences reduces serious accidents.

In this paper, an effective curriculum for the department related to industrial safety and health is developed through task analysis by the following approaches. The first approach is DACUM. The method is reflected the demand of industrial fields on subjects in curriculum. In this paper, DACUM workshop involves a trained DACUM facilitator and a committee of 6 expert workers from industrial safety and health area. 21 subjects which are necessary in the industrial fields have been selected by the DACUM analysis. The other is to understand the relative importance among each subject by AHP method. The relative importance of the subject is shown in the order of safety management, mechanical safety, construction safety, human factors engineering and system safety, chemical safety, electric safety by AHP analysis. The competition of department can be improved, if the result of this research is adapted to the department curriculum related to industrial safety and health.

This study tested the electrical, structural, and thermal safety of LED lighting products, available on the market. Five recessed LED systems, 20 W each, and five fixed LED systems, 25 W each, were selected. Dielectric strength tests, live part electric shock protection tests, and thermal tests were conducted on the LEDs. These were key tests for user safety, according to the specification of the safety criteria for electric products, KC 60598-1, South Korea. In addition, the wiring temperature of UL1007, 60227 IEC 08, and UTP cables, was measured. The results of the study gave an in-depth examination of the safety of LED lighting systems for users.

Recently, Concerns of imbalance for power supply has been raised by the increase of electric power consumption, but the interest of electric safety is still lacking due to the incompleteness of regulations. Particularly, Arcing fault, direct cause of electric fire accidents, is difficult to detect, interrupt due to unformal signal behaviour in previous research and apply to real system. In this paper, Arcing fault simulator device was fabricated to investigate the characteristics of series arcing fault and simulated the faults in various real load. Also, this study are analysed arcing fault signal by using the harmonic analysis of the acquired data from the current of the power supply and proposed the methods to prevent the series arcing fault accidents in advance.

The purpose of this study was to develop and evaluate the educational program of life safety for low grade elementary school students. The objectives of the life safety education were established, and the contents and instructions of the educational program were organized according to the needs of the 560 children and their mothers. Both experimental and control groups were evaluated before, immediately after and 3 weeks after the education in terms of knowledge about safety, attitudes and behaviors. The results of this study were as follows: 1. Twelve contents for safety education consisted of safety for electronic games, playing facility, mobile exercise machines, elevator/escalators, traffic and prevention for injury, pricking/cutting, collision/fall/slippery, drowning, burning, electric shock, food toxicity and child missing/sexual harassment/kidnapping. 2. The score of knowledge for safety, attitude, and behavior of the experimental group was improved after the post-tests. Thus, the educational effects were demonstrated to be significant in all evaluation sections.

Transuranic nuclides (such as ²³⁸Pu, ²⁵²Cf, ²⁴⁹Bk, etc.) have a wide range of application in industry, medicine, agriculture, and other fields. However, due to the complex conversion chain and remarkable fission losses in the process of transuranic nuclides production, the generation amounts are extremely low. High flux reactor with high neutron flux and flexible irradiation channels, is regarded as the promising candidate for producing transuranic nuclides. It is of great significance to increase the conversion ratio of transuranic nuclides, resulting in higher efficiency and better economy. In this paper, we perform an optimization design evaluation of producing transuranic nuclides in high flux reactor, which includes optimization design of irradiation target and influence study of reactor core loading. It is demonstrated that the production rate increases with appropriately determined target material and target structure. The target loading scheme in the irradiation channel also has a significant influence on the production of transuranic nuclides.

To effectively deal with video data, a semantic-based retrieval scheme that allows for processing diverse user queries and saving them on the database is required. In this regard, this paper proposes a semantic-based video retrieval system that allows the user to search diverse meanings of video data for electrical safetyrelated educational purposes by means of automatic annotation processing. If the user inputs a keyword to search video data for electrical safety-related educational purposes, the mobile agent of the proposed system extracts the features of the video data that are afterwards learned in a continuous manner, and detailed information on electrical safety education is saved on the database. The proposed system is designed to enhance video data retrieval efficiency for electrical safety-related educational purposes.
