Purpose: To identify the effects of a smart program for the patients who underwent percutaneous coronary intervention (SP-PCI) on coronary disease-related knowledge, health behaviors, and quality of life. Methods: A nonequivalent control group with a non-synchronized design was utilized and 48 participants (experimental=22, control=26) were recruited from a university hospital in Gyeongsang area from May to December, 2016. The 12-week SP-PCI consisted of self-study of health information using smart phone applications (1/week), walking exercise (>5/week) using smart band, feedback using Kakao talk (2/week), and telephone counseling (1/week). Patients in the control group received usual care from their primary health care providers and a brief health education with basic self-management brochure after the PCI. Data were analyzed using the SPSS 21.0 program through descriptive statistics, $x^2$ test, and t-test. Results: After the 12-week SP-PCI, the experimental group showed higher levels of coronary disease-related knowledge (t=2.43, p=.019), heart-related health behaviors (t=5.96, p<.001), regular exercise (Z=-4.47, p<.001), and quality of life-MCS (t=3.04, p=.004) and showed lower levels of stress (Z=-3.53, p<.001) and sodium intake (t=-4.43, p<.001) than those in the control group. There were no significant group differences in medication adherence and food intake in total energy, lipids, and cholesterol. Conclusion: The suggested SP-PCI provided easy access and cost-effective intervention for patients after PCI and improved their knowledge of the disease, performance of health behaviors, and quality of life. Further study with a wider population is needed to evaluate the effects of SP-PCI on disease recurrence and quality of life for patients after PCI.

일상생활 속에서 자주 접하는 대상 또는 경험을 학습에 활용하면 학생들로 하여금 공부에 대하여 보다 더 관심을 가지게 하고, 주변 환경 및 실생활과의 연계성을 파악하게 하는데 효과적이다. 하지만 일상생활 속 소재를 이용한 기존의 학습방식은 학생들이 공부에 좀 더 쉽고 편하게 접근할 수 있도록 하는 긍정적인 효과를 가지고 있음에도 불구하고, 학습 설명을 위한 예시나 상황 배경으로만 실생활 소재를 사용한다는 부분에서 한계를 가지고 있다. 학생들은 일상생활 속에서 다양한 상황을 접할 수 있는데, 그 중 학습과 연계할 수 있는 상황 맥락들이 존재한다. 이러한 일상생활 속 상황 맥락에 맞춰 적절한 학습이 이루어지게 되면 학습자는 자신이 마주하고 있는 상황이나 대상을 통해 공부할 수 있어, 보다 높은 몰입감을 경험하고 이해를 높일 수 있다. 따라서 본 연구에서는 스마트 디바이스를 이용하여 일상생활 속의 맥락을 활용하는 학습 방안을 모색하였으며, 사례를 통하여 제안함으로써 학습의 효용성을 보이고자 하였다. 이를 위해 문헌을 통하여 일상생활 속 맥락을 기반으로 이루어지는 학습의 교육적 의의와 이에 대한 지원도구로써 스마트 디바이스의 특성을 파악하였다. 그리고 학습 경험에 대한 사용자조사를 통하여 일상생활 속 맥락 기반의 학습서비스를 디자인하기 위한 가이드라인을 도출하였으며, 이를 바탕으로 사례 연구로써 과학 학습을 제공하는 학습 시나리오를 제안하고 구체적인 UI화면을 디자인하였다.

Korea is ranked as the world's No. 1 country in its aging rate. While the interest and demand for health is rapidly increasing, the health status of the elderly is in the lowest among OECD members. Increased chronic diseases, the burden of medical costs and digital/untact changes of societies after COVID-19 have caused the direction of healthcare to be changed from treatment oriented to health care and prevention oriented, along with increased income levels and a desire for a healthy life. Amid this paradigm of change, the gap in health standards and health inequality for the elderly according to local structure and social conditions affects not only socio-economic but also the quality of life for individual senior citizen. Utilizing prior data of Aging Research Panel Survey, this study aims to compare and analyze health conditions and regional gaps which are significant influences on the satisfaction of the life of the elderly, and to suggest direction of studies for health care to provide solutions for health inequalities. The findings are intended to be a basic data for researching models of the New Normal Smart Healthcare System that bridge the health gap between the elderly and enhance life satisfaction with health care models suitable for regional characteristics in aging society.

Smart Work is a way of working independent of time and space restrictions with the help of ICT. For past years, Korea has been promoting Smart Work to boost ICT industry, to overcome low birth rate and population ageing, and to implement Smart Korea. Three elements of Smart Work include people, technology and space. A lot of research has been performed on people and technology for Smart Work. But it is hard to find research on space. In this paper, some representative smart work centers(SWCs) in Korea were selected and analyzed from the perspective of spatial design including general characteristics, personal spaces, group spaces, and support spaces. From this research, it is observed that current SWCs in Korea are good in providing personal work spaces and simple group meeting rooms as well as ICT environments. However, they lack of openness to the public and group spaces to encourage informal communications. It is also observed that personal space plans need to be multi-functional, and that novel supporting spaces are required to improve quality of life and creativity of workers.

IAs smart device penetration rate is more than 90%, mobile transaction ratio using smart device is increasing. Smart contracts are used in various areas of real life including smart trading. By applying smart contracts to the platform for smart transactions through block-chain technology, the threat of hacking or forgery can be reduced. However, various threats to devices in smart transactions can pose a threat to the use of block chain Etherium, an important element in privilege and personal information management. Smart contract used in block chain Ethereum includes important information or transaction details of users. Therefore, in case of an attack of privilege elevation, it is very likely to exploit transaction details or forge or tamper with personal information inquiry. In this paper, we propose a detection and countermeasure method for privilege escalation attack, which is especially important for block chain for secure smart transaction using block chain Ethereum. When comparing the results of this study with the results of similar applications and researches, we showed about 12~13% improvement in performance and suggested the future countermeasures through packet analysis.

The smart cities are evolving constantly and are responsible for the current transformation of cities and countries into a completely connected network of information and technology This interconnected network of a huge number of smart devices is capable of exchanging complex information and provides tremendous support including enhanced quality of life within urban locations. Unfortunately this set-up is vulnerable to security attacks and requires the widespread ubiquitous network to authorize access through privacy and thus offer security in order to ensure civilian participation in a country. The smart network should benefit the individuals of the country by developing potential strategies to protect the smart cities and their participating entities from the unauthorized attacks. Trustworthy data sharing strategies based on the utilization of advanced technology features via smart communication network could solve some issues of privacy and security. This paper presents the challenges and issues related to protection and highlights the important aspects of securing the smart cities and its components. It also presents the role of cloud security for building a secure smart city.

Internet of Things (IoT) will transform our daily life by making different aspects of life smart like smart home, smart workplace, smart health and smart city etc. IoT is based on network of physical objects equipped with sensors and actuators that can gather and share data with other objects or humans. Secure communication is required for successful working of IoT. In this paper, a total of 13 lightweight cryptographic algorithms are evaluated based on their implementation results on 8-bit, 16-bit, and 32-bit microcontrollers and their appropriateness is examined for resource-constrained scenarios like IoT. These algorithms are analysed by dissecting them into their logical and structural elements. This paper tries to investigate the relationships between the structural elements of an algorithm and its performance. Association rule mining is used to find association patterns among the constituent elements of the selected ciphers and their performance. Interesting results are found on the type of element used to improve the cipher in terms of code size, RAM requirement and execution time. This paper will serve as a guideline for cryptographic designers to design improved ciphers for resource constrained environments like IoT.
