The electronic documents have the documental aspect that can legible by human and the electronic aspect that can be interpreted and processed automatically by machinery. This usability of electronic documents must be the reason that people use them in almost all the business areas rapidly in these days. That is because we have to utilize the characteristics to interchange electronic documents(EDI) effectively and efficiently. The electronic document interchange of Korean government cannot make the best of this benefit due to the traditional way of thinking based on paper document and the viewpoint of individual business, organization. and project. This paper proposed a direction of ED! for Korean government. At first. the concept of electronic docuemnts is defined. The reason and limitations of structuring the documents with XML and the hidden problems of present ED! in Korean public sector are also explained. And the way to preserve information, to design the structure of electronic document. and to maintain relevant standards is proposed.

Owing to the established international standards for reliability and safety management of railways and the third-part conformity assessment implementation, quantitative risk assessment focusing on communication system related to railway safety has being implemented. The quantitative risk assessment starts from the establishment of quantitative RAMS requirements; the risk has to be maintained under an acceptable safety level. This paper introduces the risk assessment process based on international standards ; risk assessment was conducted using failure data for railway facilities for about 5.5 years. In addition, based on the results, a scientific risk management method for railway facilities is suggested.

Concrete placement work is executed using temporary structures such as formwork, support, etc. The temporary structures could collapse when they are not properly supported, and need to be monitored for structural safety. This paper introduces a USN (Ubiquitous Sensor Network)-based monitoring system that are being tested at the Pusan National University for increasing structural safety. The system takes advantage of ubiquitous technologies together with a variety of sensors, which allows for wireless transmission of construction monitoring data. The temporary structures are constantly monitored to find out whether the structures are being supported in a stable condition. A field test is being conducted to acquire data, and use them for evaluating the safety condition of the construction operation.

The demands for (a) individual vehicle has been gradually increasing recently due to increase of personal income and spare time. In 2009, the quantities of registered vehicles exceeds over 17,325,210 millions pieces, and the risks of traffic accidents and traffic jam are increasing days by days. It has some limitations to solve the problem of traffic jam by transportation facilities and causes lots of time and costs. For a possible solution, ITS(Intelligent Transport System) has been introduced, but it is an insufficient way for abrupt incidents or risks on roads. The riskiest matter on driving a vehicle is unforeseen situation. In this paper, the most efficient and economical system that communicates with a driver about unexpected accident by sensor network and GPS information, is introduced rather than a traditional method associated with lots of time and costs.

Objectives: This study aimed to examine systems behavior of urban walking by analyzing a dynamic structure in Seoul, South Korea. Methods: As a systems thinking approach to urban walking and health promotion, we developed a Casual Loop Diagram based on literature review and expert consultation. The reviewed literature included: 1) qualitative studies that explores the experiences of urban walkers in Seoul; 2) a systematic review study on the built environmental factors related to walking; 3) policy research reports related to urban walking in Seoul. Results: The feedback structure for urban walking was related to the three urban environments (safety & walking environment, socioeconomic environment, and public transportation environment), and was characterized by a trade-off consisting of eight reinforcing loops and four balancing loops. Conclusions: The policies for a walkable city require multi-sectoral cooperation in order to change the causal loop structure related to the decline of walking. Therefore, it is necessary to establish legal and institutional conditions so that multi-sectoral and multidisciplinary approaches are possible.

Purpose: Traffic accidents are the major cause of death in children. Car seat usage in children is important to reduce the risk of death or injury caused by traffic accidents. This study aims to analyze the trends of car seat use among children ages under 6. Methods: This study adopted a cross-sectional study utilizing the Korea National Health and Nutrition Examination Survey from 2015 to 2019. In total, 1,999 responses were included for the analysis. Factors associated with car seat use were age, sex, body weight, height, family type, household income, and monthly household income. Regression analysis was used to compare the car seat use before and after the revision of the Road Traffic Act (2015~2018 vs. 2019). Results: We found that car seat use was increasing by year, age, region, and household income. Car seat use was higher after fines increased in 2019. Age and body weight had negative association with car seat use, while height and household income had positive association with car seat use. Conclusion: Car seat use increased from 2015 to 2019 and is associated with different ages among children and household income. Further education and promotion that describes the safety benefits to children from car seat use are needed.

Purpose: It is important to operate safely and economically in obsolescent power plant facilities. Economical operation is related in the balance of the supply and demand. Safety operation predicts the possible risks in the facilities and then, takes measures to the facilities. For the monitoring of the power plant facilities, we needs several kinds of the sensing system. From the sensors data, we can predict the possible risk. Method: We installed the acoustic, vibration, electric and smoke sensors in the power plant facilities. Using the data, we developed 3 kinds of prediction models, such as, demand prediction, plant engine abnormal prediction model, and risk prediction model. Results: Accuracy of the demand prediction model is over 90%. The other models make a stable operation of the system. Conclusion: For the sustainable operation of the obsolescent power plant, we developed 3 kinds of AI prediction models. The model apply to JB company's power plant facilities.

The low-voltage connection box used as a low-voltage transmission line of KEPCO is intended to branch or connect to an underground line. In comparison with the utility considering the aesthetics of the distance, and safety measures are needed. In this paper, temperature and humidity, $CO_2$, water level, acceleration, and vibration sensor are installed inside the underground low voltage handhole, and the sensor data is transmitted to the ground using the Zigbee module. Antenna (Bolted Antenna) for communication with the ground was proposed and the data reception through it was confirmed. In the LF mode and the HEX mode, the transmitted data was confirmed to be a perfect reception success rate. In the case of the bolted antenna, the difference between the ground state and the underwater state was observed as a result of the experiment in the environmental environment. However, It was judged that reception sensitivity was sufficient for communication. The received data could be confirmed through PC based GUI.

The importance of gamification is garnering increased attention in the corporate world. Gamification refers to using game mechanics and thinking patterns in non-game domains to promote user engagement. By reviewing the definition of gamification and related literary research, we aim to understand how to put theory into practice and determine the organization of gamification's main features. Next, in order to understand the current implementation methods of mobile payment gamification marketing. We analyze popular mobile payment apps as case studies. To examine the effectiveness of game mechanics on mobile payment marketing to determine whether there is a positive impact on brand loyalty and stickiness. The results are used to identify shortcomings in gamified mobile payment systems. Finally, we propose a gamification framework model for mobile payments and offer recommendations for underutilized game mechanics based on previous cases. Future research can reference our model for deeper studies on the effectiveness and impact of gamified mobile payments.
