In the revision of the national curriculum, various creative activities and career activities are highlighted under the goal of fostering creative talent. Following the implementation of this policy, which is represented by creative activities, teachers are burdened with comprehensive responsibilities, such as planning and executing safety procedures and preventing accidents. Existing systems for teacher management had limitations that allowed only the provision of standardized information and management. The main purpose of this study is to help teachers manage their classes systematically through a class management system. The teachers' overall management system includes several functions, such as checking students' locations, registering students' reviews, or registering various kinds of activities for the creative experiential activities of the curriculum. This system not only helps teachers to systematically manage the creative experiential activities, but also allows teachers to share the history of their activities with each other. Furthermore, this system will be helpful in achieving the objectives of the revised curriculum.

In order to reduce the spread of infection due to COVID-19, South Korea has established a four-step social distancing standard and implemented it by changing the steps based on the rate of confirmed cases. The implementation of social distancing brought about a change in the amount of activity of citizens by limiting social contact such as movement and gathering of people. One of the data that can intuitively confirm this is Night Time Light (NTL). NTL is a variable that can measure the size of the national economy measured using lights captured by satellites, and can be used to understand people's social activities during the night. The NTL visible data is obtained via the Visible Infrared Imaging Radiometer Suite (VIIRS) Day-Night Band (DNB) onboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite. 1023 of Suomi data from 1 January 2019 until 26 October 2021 were collected to generate time series of NTL radiance change over Seoul to analyze the correlation with social distancing policy. The results show that implementing the level of social distancing generally decreased the NTL radiance both in spatial disparities and temporal patterns. The higher level of policy, limiting human activities combined with the low number of people who have been vaccinated and the closure of various facilities. Because of social distancing, the differences in human activities affected the nighttime light during the COVID-19 pandemic, especially in Seoul, South Korea. Therefore, this study can be used as a reference for the government in evaluating and improving policies related to efforts reducing the transmission of COVID-19.

This study investigated the correlation between smartphone addiction and eating behaviors of 288 elementary school students (fifth and sixth grades) in the Ansan area. Addiction and normal groups consisted of 29 (10.1%) and 259 students (89.9%). Average usage time of the smartphone addiction group was higher than that of the normal group (P<0.001). Percentages of using a smartphone when eating meals as well as skipping meals due to using a smartphone were also higher in the addiction group than the normal group (P<0.01). Degree of reduction of physical activity and sleep disorders due to using a smartphone were higher in the addiction group than the normal group (P<0.001). However, nutritional knowledge related to protein and dietary life scored lower in the addiction group than the normal group (P<0.05). Correlation between smartphone usage time and eating behaviors was as follows: smartphone usage time on weekdays increased with elevated usage time on weekends in the addiction group (+0.742) (P<0.001) and the normal group (+0.762) (P<0.001). Frequency of snack intake in the addiction group increased with elevated usage time on weekdays (+0.460) (P<0.05). Sleeping time of the normal group decreased with elevated usage time on weekdays (-0.150) (P<0.05), and good eating behaviors decreased with elevated usage time the on weekend (-0.143) (P<0.05). Consequently, smartphone addiction in elementary school students showed negative eating behaviors. Therefore, effective nutritional education programs and national support policy are required to solve problems of unhealthy eating behaviors from smartphone usage in elementary school students.

Organizations depend on smart working environments, such as mobile networks. This development motivates companies to focus on information security. Information leakage negatively affects companies. To address this issue, management and information security researchers focus on compliance of employees with information security policies. Countermeasures in information security are known antecedents of intention to comply information security policies. Despite the importance of this topic, research on the antecedents of information security countermeasures is scarce. The present study proposes information security intelligence as an antecedent of information security countermeasures. Information security intelligence adapted the concept of safety intelligence provided by Kirwan (2008). Information security intelligence consists of problem solving skills, social skills, and information security knowledge related to information security. Results show that problem solving skills and information security knowledge have positive effects on the awareness of employees of information security countermeasures.

As the number of users of SNS (Social Network Service) and smart devices increases sharply nowadays, many studies on various teaching models and methodologies have been made in order to utilize SNS in education. However, there are not so sufficient studies that explore social media as a learning environment and analyze empirically its relation with the academic achievement. Since various kinds of learning experiences are required in order to foster creative talents, it is necessary to have information sharing, debate and information exchange utilizing SNS. If utilizing SNS for general computer education in a university, it will be possible to collect learners' various thoughts and opinions more effectively. Because real-time feedback can be possible in each individual space through SNS by sharing the information related to the interactions between learner and teacher or between leaner and learner and exchanging opinions each other, the learner's ability to utilize a computer can be improved. Especially SNS can provide a real-time help to solve problems for underachieved students and provide an opportunity to improve the academic achievement.
