  • Falls are accidents that can happen throughout the overall period of human life and their results are very fatal and have a serious negative effect on individuals and society. In case of aged people, even though they live in places where dangerous risks of falls are prevalent, they cannot improve their residential environment for themselves. Therefore, this study intends to prove the effects of fall prevention education by providing fall prevention education to spatial design majoring students in order to improve their perception about the falls and fall prevention environments and their social responsibility as a designer. This study was designed as Quasi-experimental study, and 121 beginners to spatial design received the education. As a result, the effects of education was proved by showing improvements on their awareness about the fall risks, the importance of fall prevention environment and social responsibility as a designer. In addition, after the education students could know more about spatial elements for fall prevention and they specified the details of important environmental factors for fall prevention. Generally, fall prevention education has been given to aged people and this is a first example of fall prevention education that was given to younger generation. It is meaningful that fall prevention education has changed the awareness of the students to help them work in spatial environment design with a strong sense of responsibility as an expert of spatial designer in future.

  • Spontaneous ignition is not only severe economic damage but also a typical plant damage caused by harmful gases generated during the fire. Because coal is porous, it causes oxygen to be absorbed in the amount of oxygen per unit weight of oxygen, resulting in low humidity and low thermal conductivity. The cause and effect of spontaneous ignition are very complex, so it is difficult to prevent it beforehand and once it is difficult to digest it, it is difficult to digest it. This study examines structural safety by conducting a structural analysis of the cooling ball system to prevent spontaneous combustion of coal stockpile plants and external pressures.

  • IT technology of U-healthcare system is being grafted onto medical services and the use of U-healthcare system are extending steadily. However, in case of patients using Implantable Medical Device (IMD) in U-healthcare system, patients' privacy protection and safe access to system recently has emerged as a major issue. This paper proposes a patients' privacy protection protocol to prevent any illegal accesses from third parties as state value and action value are synchronized after patients' information virtualization. The proposed protocol can limit the access range of patients' information according to authentication information of hospitals, doctors, nurses, and pharmacies registered in the U-healthcare server. Additionally, this protocol can increase management efficiency for patients' privacy by synchronizing state values and action values only for approved information and, by instituting this process, third parties cannot easily access patients' information.

  • As a substitute for preventing school violence, the reward and punishment system has some problems such as different imposition basis for each teacher, ambiguity of applicable items, and difficulties in directing students in relation to parents of students. In this thesis, a reward and punishment points management system is implemented based on the web to solve the problems. The week point of the current system is complemented by separating the system into four parts, operating each part that is operated by administrators, teachers, students and their parents respectively and sharing their data. In addition, as each group of administrators, teachers, students and their parents is organically connected to the system, when special problems occur, the problems can be solved effectively. Therefore, if the implemented system is used in the field, the guidance of human nature is naturally conducted by understanding broadly for student's living guidance. Furthermore, it can be helpful to prevent students from school violence in advance.

  • In this paper, we suggest a plan to take advantage of the SNS data to proactively identify the information on crime risk factor and to prevent crime. Recently, SNS(Social Network Service) data have been used to build a proactive prevention system in a variety of fields. However, when users are collecting SNS data with simple keyword, the result is contain a large amount of unrelated data. It may possibly accuracy decreases and lead to confusion in the data analysis. So we present a method that can be efficiently extracted by improving the search accuracy through text mining analysis of SNS data.

  • The research was conducted to investigate the effect of drama education on the empathy and prosocial behavior abilities of middle school students. A total of 45 students participated in this study. Data were obtained through the use of the IRI(Interpersonal Reactivity Index) and the prosocial behavior scales. Those scales were administered to the group of students as a pre-test. Then, drama education was provided for 14 weeks for the group. The same scale was applied again to the group as a post test once the drama education was completed. The t-test on the differences between pre- and post test scores was used to analyze the effects of the program. The results showed that drama education had a statistically significant effect on the empathy and prosocial behavior abilities of students in the group. Finally, this study suggested implications for future performance arts education programs.

  • in 2010s, many factories are operating without any safety guarantees due to the aging process. Although it is difficult to fundamentally solve the problem of aging process and equipment, Prevent risk by risk assessment in advance. This study targets the corrosion caused by sulfur in the piping in the CDU(Crude Distillation Unit) process desulfurization equipment and conducts the risk assessment by RBI(Risk Based Inspection) referring to API RP 581. RBI expresses the risk by combining frequency and consequence, and creates a risk matrix based on these expression. In this study, the hole size of the pipe was selected as Small and Medium, and the sensitivity of the frequency was selected as 'Low'. You can refer to the Risk Matrix created from the standard to evaluate the risk of corrosion of sulfur from pipes in the piping and to plan future accident prevention. Similarly, prevention of aging in a similar way can prevent large and small incidents that are not visible.
