The number of elderly people living alone increases with the trend of nuclear family in recent aging society and advances of health and medical technologies, where the safety of the elderly people becomes a big social issue. One of the safety system for them these days is that security guards regularly visit homes of the elderly living alone to check their safety. However, it is an inefficient system since it costs a great deal. So, a new efficient system with low cost using modern advanced technologies needs to be developed. In this paper, we implement a monitoring system for elderly living alone using ubiquitous sensor and zigbeX. The system can remotely determine the health status of elderly people and report to their hospitals. Since the system can be implemented with low cost and do the same job as security guards do, we expect that it should replace the existing expensive monitoring system.

A discussion on false alarm is a series of problems about a waste of police resources. The the false alarm primarily increase machine the cost of security firm but ultimately increase the costs of national and social management. Verified Report System has been in operation since July 1, 2013, We could analyze the actual operation of 112 report on false alarm rate was 82.4% before this system launched, but after implementation of the Verified Report System, this rate level downs below 69.7% records. So 12.7% is declined at the rate of false alarm. However, the actual alarm rate of Electronic Security itself is just only 0.3 % in the total number of cases responding in contrast to Police is considerable. It is more urgent to evolve the Verified Report System, so penalty system against the false alarm, Police registration system of sensors, and strengthening of the task of the company for installation and management of detection equipment are urgently needed.

According to Neo-liberalism, the privatization of social security systems is pivotal for a country's economic growth and the wellbeing of its people, because such systems hinder the full operation of the market, eventually leading the national economy to collapse. The Chilean case of pension privatization is often cited as a good evidence for the Neo-liberal argument. Neo-liberalists say that Chile has experienced a rapid economic growth and retirees have enjoyed a much more pension payment since the national pension system was successfully privatized in 1981. The primary purpose of this article is to provide a critical review on the results of the Chilean pension privatization reform implemented in 1981. This study is intended to give an objective understanding of the reform because the existing evaluations, particularly those from the neo-liberalism, over-emphasize the bright sides of the reform. for this purpose, this article will pay a particular attention to the change in the level of pension payment after the reform. The conclusion of this study is that, contrary to the argument of Neo-liberalism, the pension reform has lowered the level of pension payment and, compared to the old public pension, has made the lives of ordinary retirees less secure. Reorganization of the social security system is more desirable than privatization as a remedy for the current problems of the welfare state.

As the elderly population is becoming an aging society, the elderly are experiencing many problems. Social security costs for the elderly are increasing and the un-linked social phenomenon is emerging. Thus, the social infrastructure and welfare system established in the past economic growth period are in danger of not functioning properly. People socially isolated or with chronic diseases among the elderly are exposed to various accidents. Thus, an active healthcare management service is imperative. Additionally, in the event of a dangerous situation, the system must have ways to notify guardians (family or medical personnel) regarding appropriate action. Thus, in this paper, we propose the smartphone-based healthcare and emergency response service platform. The proposed service platform aggregates movement of relevant data in real-time using a smartphone. Based on aggregated data, it will always recognize the user's movements and current state using the human motion recognition mechanism. Thus, the proposed service platform provides real-time status monitoring, activity reports, a health calendar, location-based hospital information, emergency situation detection, and cloud messaging server-based efficient notification to several subscribers such as family, guardians, and medical personnel. Through this service, users or guardians can augment the level of care for the elderly through the reports. Also, if an emergency situation is detected, the system immediately informs guardians so as to minimize the risk through immediate response.

Purpose: The goal of this study is to examine what makes young people more likely to use digital banking. This is because digital banking services and their distribution channels are technologically advanced, which can be a double-edged sword between ease of use and resistance to technology. Research design, data and methodology: This study included 320 participants from generation Z in Jakarta who use digital bank and used a quantitative method with PLS-SEM. Results: This study explains how, in addition to usefulness, costs, and self-efficacy, resistance to technology has a direct effect on usage attitudes. Meanwhile, if the attitude of use is preceded by aspects of usefulness, self-efficacy, and awareness, resistance to technology will be felt indirectly. Conclusions: This demonstrated that most discussed factors, such as Ease-of-Use and security of use, are important for Generation Z users but no longer a major consideration in accepting digital banking. Aside from being more open to the use of technology in digital banks, Generation Z also desires a balance of technology services and benefits. The limitations of this study are that it excludes social variables, uses certain generations, and limits the research area to one large city, which can be expanded in future studies.

Credit card is means of payment used like cash in terms of function and its users have increased consistently. With development of Internet and electronic commerce a role as payment method of credit card has been growing. But as the risk which results from centralized information and online increases, credit card fraud is also growing. Card theft and loss are decreasing due to countermeasure of card companies and financial supervisory authorities, while card forge and identity theft are increasing. Recently because of frequent personal information leakage and deregulation of financial security following easy-to-use payment enforcement, customer's anxiety about card fraud is growing. And the increase of card fraud lowers trust on credit system as well as causes social costs. In this paper, the security problems of card operating system are addressed in depth and the measures such as immediate switch to IC card terminals, introduction of new security technology, supervision reinforcement of the authorities are proposed.

Recently, the advancement of information and communication technology(ICT) is expanding the connectivity through Internet of Things(IoT), and the media of connection is also expanding from wire/cable transmission to broadband wireless communication, which has significantly improved mobility. This hyperconnectivity has become a key element of the fourth industrial revolution, whereas the supervisory control network of purification plants in korea is operated as a communication network separated from the outside, thereby lagging in terms of connectivity. This is considered the best way to ensure security, and thus there is hardly any consideration of establishing alternatives to operate an efficient and stable communication network. Moreover, security for management of a commercialized communication network and network management solution may be accompanied by immense costs, making it more difficult to make new attempts. Therefore, to improve the conditions for the current supervisory control network of purification plants, this study developed a industrial security L2 switch that supports modbus TCP(Transmission Control Protocol) communication and encryption function of the transmission section. As a result, the communication security performance improved significantly, and the cost for implementing the network management system using Historical Trend and information of HMI(Human Machine Interface) could be reduced by approximately KRW 200 million. The results of this study may be applied to systems for gas, electricity and social safety nets that are infrastructure communication networks that are similar to purification plants.
