Recently, in the food culture life, the trend of consumers cooking is changing, and the use rate of induction cookware is increasing. Therefore, in this study, we propose the development of a functional auxiliary device to improve the safety of induction cookware to improve the convenience of cooking according to the increase in the cooking population. The proposed device is linked with IoT through the app. Through the app, the device can control the induction heating power adjustment and time reservation. In addition, an ultrasonic sensor is used to prevent the container from overflowing during cooking, and the user can safely use induction through the fine dust sensor. The implemented device conducts research assuming the actual cooking situation. Finally, it was confirmed that the user's fatigue was reduced during cooking through the device and the user's safety was improved in emergency situations such as overcooking or overflowing of water.

In urban life, an interest in safety and demands for safety information about crimes and traffic are increasing. As well, communication on the internet is so active. In this study, we analyze web sites in US, UK, and JP, which have started safety map services, and then we provide basic material for the introduction of safety map into Korea. According to the analysis result, in US and UK, the safety map web sites are administered by the government and provided to the general public. The geographical area is provided around administrative districts and statistical data. In JP, The safety map web site provide not a one sided service but the service that user can directly take a part in, and also there is an web site for crimes against vulnerable people.

In the event of a short-circuit accident on a 4.16 kV non-safety bus, the voltage is temporarily lowered as backflow occurs on the safety bus. In such cases, the undervoltage relay of the safety bus shall not pick up the undervoltage so as not to interfere with the operation of the safety motors. The aim of this study is to develop an adaptive undervoltage protection scheme for the 4.16 kV safety bus considering the faults on the 13.8 kV and 4.16 kV non-safety buses connected to secondary windings of the three winding transformers, UAT and SAT. The result of this study will be the adaptive undervoltage protection scheme for the safety bus of nuclear power plants satisfying functional requirements of the safety related medium voltage motors. The adaptive undervoltage protection scheme can be implemented into an integrated digital protective relay to make user friendly and reliable protection scheme.

Safety diagnostic indicator pointer can divide by greatly two. One is management (Software) side that one that differ with mechanical (Hardware) side that handle laying stress on equipment connected with safety manages organization and management connected with safety. Weight appropriates according to specific gravity that relevant element occupies in facilities. To give so big value in particular element in grant of weight pays attention because break balance of whole guideline and should gives. Finally, efficient safety net may see effect before self-regulation inside by minimum target establishment using AHP by government and legal, systematic countermeasure establishment for this, strict law application and each business proprietor and though activity and user's active safety activity forms harmony properly.

This study performed factor analysis for 21 independent variables related to the effect of illumination and suggested the effect by multiple regression analysis on the relationship between the effect of illumination and the satisfaction of use of a dependent variable to find the effect of illumination in urban parks at night and the effect of illumination on the satisfaction of use. The results of this study are as follows; 1) Of the 21 independent variables used to study the effect of illumination in urban parks at night, the impact on safety and possibility of crime was highly. The effects of illumination by factor analysis were abstracted as effects of removing anxiety, securing safety, increasing use. 2) As a result of multiple regression analysis, independent variables influencing satisfaction of use in urban park were proved as effects of removing anxiety, securing safety, increasing identity, preparing atmosphere and increasing use. Also, the effect of securing safety was the most important factor; it showed a level of importance 2 times higher than the effect of removing anxiety, and 7.7 times higher than the effect of preparing atmosphere in relative contribution of the effect of illumination to satisfaction of use. 3) Of the effects of illumination influencing satisfaction of use in urban parks, the effect of securing safety and the effect of increasing visibility were more significant than the effects of removing anxiety, preparing atmosphere and increasing use. This fact means that personal safety an the identity of persons or facilities in the space of use should be considered with priority in planning or designing illumination. Also, it implies hat, for night use in urban parks, lightness of the space is required for general safety of use at parks, and proper illuminance on the activity in the space of use should be required. The subject parks of this study are 8 urban neighborhood parks. The model on the effect of illumination and the satisfaction of use depends on characteristics and conditions of location of he park and user class, so the subject parks and persons should be varied, and the difference by sex or ages should be suggested.

P2P(Peer-to-Peer) can compose free network and take away center server function or problem about authentication is risen between each User because is opening network that can participate between each User weakening. We desire to authenticate request about service to user who is admited between each user to limit connection. Wish to admit Kerberos authentication mechanism to mechanism that can do information sharing safety in P2P environment to solve this in this treatise and design authentication mechanism.

Purpose: The purpose of this study is to analyze how the writing rules of the product user guide affect consumers' understanding of products and the prevention of product accidents. Methods: We surveyed consumers to see how the writing rules of the product user guide help consumers to understand products and prevent product accidents. Results: We derived the importance, necessity, usability, and readability of the principle of making product manuals through analysis of previous research. Usability is the writing rule of the product user guide that the consumer has the most influence on the understanding of product use and the product accident. Conclusion: It is necessary to make product user guide so that consumers can understand the function and safety of products by using video and various image media. Also, It is the obligation to explain all stages of the product and to communicate through the product user guide how to prevent the product accident step by step.

This study made an attempt to investigate the influential factor and relationship between the type of parking lot and user satisfaction. The types of parking lot in Apartment complex considered in the research is categorized into three types : ground, underground, and combined. A questionnaire survey has been conducted for apartment complex residents to collect research data which has been used for structural equation modeling. The study result tells that the factors of accessibility, safety for pedestrians and cars, environment which are security and cleanness, and convenience are found to be influential for user satisfaction to the type of parking lot and accessibility is seen as the most influential factor among them. The crucial characteristics for user satisfaction by each type of parking lot have also been suggested such as convenience for ground parking lot, accessibility for combined type, and safety for underground type.

The purpose of this study is to understand the characteristics of O2O service which is emerging recently and to look for ways to take advantage of it. Recently, the emergence of various O2O services that utilize ICT technology of smartphone has attracted a lot of consumers. The study analyzed the characteristics of the O2O service and evaluated whether user satisfaction changes according to use safety. This study carried out a structured questionnaire, by collecting the material for the 421 general public in the country. Hypothesis tests showed that 4 characteristic of O2O services have positive impact on user satisfaction and regression analysis showed accuracy of information and pleasure have significant impact on user satisfaction. After cleaning up of these findings and discussing the theoretical and practical implications, this study provides direction for future research.
