Structural Health Monitoring (SHM) is used to provide reliable information about the structure's integrity in near realtime following extreme incidents such as earthquakes, considering the inevitable aging and degradation that occurs in operating environments. This paper experimentally investigates an integrated wireless sensor network (Wi-SN) based monitoring technique for damage detection in concrete structures. An effective SHM technique can be used to detect potential structural damage based on post-earthquake data. Two novel methods are proposed for damage detection in reinforced concrete (RC) building structures including: (i) Jerk Energy Method (JEM), which is based on time-domain analysis, and (ii) Modal Contributing Parameter (MCP), which is based on frequency-domain analysis. Wireless accelerometer sensors are installed at each story level to monitor the dynamic responses from the building structure. Prior knowledge of the initial state (immediately after construction) of the structure is not required in these methods. Proposed methods only use responses recorded during ambient vibration state (i.e., operational state) to estimate the damage index. Herein, the experimental studies serve as an illustration of the procedures. In particular, (i) a 3-story shear-type steel frame model is analyzed for several damage scenarios and (ii) 2-story RC scaled down (at 1/6th) building models, simulated and verified under experimental tests on a shaking table. As a result, in addition to the usual benefits like system adaptability, and cost-effectiveness, the proposed sensing system does not require a cluster of sensors. The spatial information in the real-time recorded data is used in global damage identification stage of SHM. Whereas in next stage of SHM, the damage is detected at the story level. Experimental results also show the efficiency and superior performance of the proposed measuring techniques.

This study examines the performance of program providers(PP) considering various factors. This study employs the panel regression models with the dataset from 2014 to 2019. This study analyzes how various market structural factors and behavioral factors have impact on the performance. The results show that the high proportion of retransmission fees to broadcasting revenue is negatively associated with total media revenue and operating income while advertising revenue is positively associated with these factors. The results imply PPs that have heavily depended on the fees have not showed a superior performance. Current PP markets are evaluated to have low average revenue per users and thus the size of retransmission fees cannot be enlarged. Under such market conditions, PPs focusing on raising advertising revenue show better performance. This study also suggests that PPs that own diverse channel assets have improved their performances.

The fast emerging of network technology and the high demand of computing resources have prompted many organizations to outsource their storage and computing needs. Cloud based storage services such as Microsoft's Azure and Amazon's S3 allow customers to store and retrieve any amount of data, at anytime from anywhere via internet. The scalable and dynamic of the cloud storage services help their customer to reduce IT administration and maintenance costs. No doubt, cloud based storage services brought a lot of benefits to its customer by significantly reducing cost through optimization increased operating and economic efficiencies. However without appropriate security and privacy solution in place, it could become major issues to the organization. As data get produced, transferred and stored at off premise and multi tenant cloud based storage, it becomes vulnerable to unauthorized disclosure and unauthorized modification. An attacker able to change or modify data while data inflight or when data is stored on disk, so it is very important to secure data during its entire life-cycle. The traditional cryptography primitives for the purpose of data security protection cannot be directly adopted due to user's lose control of data under off premises cloud server. Secondly cloud based storage is not just a third party data warehouse, the data stored in cloud are frequently update by the users and lastly cloud computing is running in a simultaneous, cooperated and distributed manner. In our proposed mechanism we protect the integrity, authentication and confidentiality of cloud based data with the encrypt- then-upload concept. We modified and applied proxy re-encryption protocol in our proposed scheme. The whole process does not reveal the clear data to any third party including the cloud provider at any stage, this helps to make sure only the authorized user who own corresponding token able to access the data as well as preventing data from being shared without any permission from data owner. Besides, preventing the cloud storage providers from unauthorized access and making illegal authorization to access the data, our scheme also protect the data integrity by using hash function.

Companies want organizational members who take e-learning courses to enjoy the advantages of transcending time and space that e-learning has, but also want what they have learned to help the organization, the work they perform, or their future careers. In addition, while enjoying the effect of reducing education costs compared to offline education through e-learning, it is expected that executives and employees will apply the knowledge and skills learned to the field and perform tasks to achieve results. As COVID-19 continues, many education programs that have been conducted offline at corporate sites have been converted to e-learning, with a larger number of e-learning operations than in the past. This study was conducted based on the perception that learners' learning satisfaction is important for the successful operation of e-learning education, and that learners' own self-directed learning ability and self-determination are important as well as corporate efforts. As a result of the study, hypotheses 1-1, 1-2, 1-3-1, and 1-3-2 that the better the self-determination (autonomy, competence, full-time support, and peer support) is, the higher the learning satisfaction will be. Both Hypothesis 2-1 and Hypothesis 2-2 were adopted that the better self-directed learning (subjectivity, execution ability) is, the higher the learning satisfaction will increase. In conclusion, it is necessary to properly introduce the concepts of self-determination and self-directed learning in corporate education while operating with the corporate education system.

As the trend towards expanding the functions of modern governments continues, there are also problems such as misconduct and waste that arise as government activities and operations increase. To solve these issues, countries are establishing and developing internal control mechanisms. In this process, the U.S. Inspector General system has been operating for over 40 years with the aim of balancing and overseeing the government and the legislature. Accordingly, this study analyzed in detail the development process of the inspector system, one of the internal control systems promoted by U.S. government agencies, the formation of an inspector community, and the deployment, cooperation, and supervision of inspectors. As a result, the internal control system of domestic government agencies also needs to continue research so that the government and parliament can maintain close relations and introduce the inspector system according to the domestic situation.

Recently, a hydrogen charging station-related memorandum of understanding (MOU) was signed between Korea Transport Institute and United Arab Emirates (UAE) Ministry of Transport in Abu Dhabi, creating a foundation for exporting green hydrogen charging stations and hydrogen powered public transit buses developed with Korean technology to Abu Dhabi. Reliable construction and operation of the charging stations require a thorough review on associated standards and legal requirements. In particular, it is essential to analyze currently effective standards related to hydrogen production, hydrogen vehicle charging, and hydrogen charging stations. This paper specifically focuses on comparative analysis of hydrogen-related standards in the UAE and the Republic of Korea. Similar to UAE, Korean hydrogen charging station-related standards follow International Organization for Standardization (ISO) standards. From real-life experiences in developing and operating charging stations, even more essence of ISO standards have been adopted in Korean standards than UAE. In particular, ISO standards related to fire prevention are additionally included in Korea. This paper also suggests procedural and administrative strategies for enabling application of Korean hydrogen charging station-related standards in UAE.
