The theme, background, and signal music usage history information consists of general information such as music information, platform information, and music usage information, and sensitive information such as rights management information, music usage permission range, and contract information. If sensitive information among these is disclosed, disputes such as trade secrets and infringement of personal information protection between companies or between companies and individuals may arise. We propose a selective encryption/decryption method to secure the confidentiality, integrity, reliability and non-repudiation of sensitive music usage history information used in the theme, background, and signal music blockchain environment. In the proposed method, a monitoring company encrypts sensitive information using a secret key for usage history information, which is combined with general information, and digitally signs it using a private key to register it in a block. A trust group can view and access the information at the time of inquiry by verifying the digital signature with the public key of the monitoring company and then can decrypt the sensitive information using the private key.

With the development of the 4th industry, big data using AI is being used in many areas of our lives, and the importance of data is increasing accordingly. In particular, as various services using personal information appear and hacking attacks that exploit them appear in various ways, the importance of personal information management is increasing. Personal information must be managed safely even when collecting, retaining, using, providing, and destroying personal information, and the rights of information subjects must be protected. In this paper, an analysis was performed on the notification of usage history during the protection of the rights of information subjects using the MyData model. According to the Personal Information Protection Act, users must be periodically notified of the use of personal information, so we notify each individual of the use of personal information through e-mail or SNS once a year. It is difficult to understand and manage which company use my personal information. Therefore, in this paper, a personal information usage history notification system model was proposed, and as a result of performance analysis, it is possible to provide the controllability, availability, integrity, source authentication, and personal information self-determination rights.

In this paper, we propose an intelligent research fund management system that applies artificial intelligence technology to an integrated research fund management system. By defining research fund management rules as work rules, a detection model learned using deep learning is designed, through which the disapproval status is presented for each research fund usage history. The disapproval detection system of the RCMS implemented in this study predicts whether the newly registered usage details are recognized or disapproved using an artificial intelligence model designed based on the use of an 8.87 million research fund registered in the RCMS. In addition, the item-detail recommendation system described herein presents the usage details according to the usage history item newly registered by the artificial intelligence model through a correlation between the research cost usage details and the item itself. The accuracy of the recommendation was shown to be 97.21%.

As an useful application in broadcasting services, the targeting service has been mainly studied to improve the service satisfaction and user usage in various media service environments based on user profile, preferences, and usage history. Targeting service is expanding its domain from broadcasting contents to interstitial contents and from fixed TV devices to mobile devices. Service data also include advertisement data, coupon, and information about media contents as well as simple broadcasting data. In this paper, the targeting data service is designed and implemented on articles, advertisement and broadcasting information on the basis of the user information. To adapt this to web-based media contents, information on user profile, preferences, and usage history is newly defined on the basis of the user metadata developed in TV-Anytime Forum and the user information defined in OpenSocial. The targeting data service is implemented to generate user preferences information and usage history pattern based on the similarity among user preference, contents information, and usage history. Based on performance evaluation, we prove that the proposed targeting data service is effectively applicable to web-based media contents as well as broadcasting service.

This study is a study on the effect of technical readiness factors on counselors' intention to use when applying AICC. AICC counselors experience improved customer service and emotional stability by receiving various monitor notification window services based on artificial intelligence algorithms such as customer counseling history, prohibited word control system, and customized counseling system. Accordingly, this study tried to verify using factors derived from technology readiness theory and technology acceptance theory among the factors affecting the intention to continue using AICC provided to counselors. To verify the research hypothesis, the causal relationship between variables such as Optimism, Innovativeness, Discomfort, Insecurity, and Technology Acceptance Theory, such as Team Support, Ease of Usage, and Innovation Resistance, was verified. As a result of empirical analysis, first, it was verified that Optimism has a positive (+) effect on Team Support and Ease of Usage, and Discomfort and Insecurity have a negative (-) effect on Ease of Usage and Team Support. Second, it was confirmed that Team Support and Ease of Usage had a positive effect on the Intention to use AICC. Based on the above empirical analysis results, the concepts of Technical Readiness were clearly proved, and in practical terms, AICC helped inquiry, quality evaluation, recording, and management of counseling history, ultimately increased corporate work efficiency.

Gallbladder stones in children are not common without underlying hemolytic diseases or other risk factors like obesity. Ceftriaxone, a third generation cephalosporin, is known to make biliary precipitations that can be mistaken for biliary stones. We here report two children with biliary pseudolithiasis with different treatment modalities. One child was mistaken for symptomatic gallbladder stones and underwent elective laparoscopic cholecystectomy, while the other child, after thorough history taking on the ceftriaxone medication, was suspected of biliary pseudolithiasis and was treated conservatively. Both children had the history of usage of ceftriaxone in previous hospitals for infectious diseases. The ceftriaxone history of the first child was missed before the surgery. When gallbladder stones are found in children without any underlying diseases, specific history taking of the usage of ceftriaxone seems to be absolutely required. In this case, immediate interruption of the antibiotic could resolve the episode and avoid unnecessary surgical procedure.

Unsatisfied with the modern medicine's treatment of diabetes, patients diagnosed with the disease turn to alternative medicine for treatment. A look at the percentage of people using alternative medicine marked 72.8% in the United States and more than 60% in Korea in 2006. The most preferred form of alternative medicine turned out to be usage of dietary supplements and herbal medicine. Most of the dietary supplements and herbs that diabetic patients use largely originated from their usage in East Asian Traditional Medicine. As Western Medicine made its way into East Asia in late 18th century, excessive efforts were made to translate Western medical terminology into traditional medical terminology equivalents. In the process of doing so, wasting-thirst became a concept equivalent to diabetes. Theories regarding the pathogenic outbreak and transmission of wasting-thirst has been supplemented and progressed according to needs and even showed new tendencies. Profound understanding of wasting-thirst achieved through historical research is expected to lead to proper application of wasting-thirst treatment methods in treating modern diabetes.

Decay usage scheduling algorithm gives preference to processes that have consumed little CPU in the recent past. It has been widely-used in time-sharing systems such as UNIX, where CPU-intensive processes and interactive processes are mixed. However, there has been no sound understanding about the mixed effects of decay usage parameters on the service performance. This paper empirically analyzes their effects in terms of the resulting service bandwidth and delay Based on such empirical analysis, we derive the clear meaning of each parameter. Such analysis and understanding provides a basis of controlling decay usage parameters for desirable service provision as required by applications.

Ginseng, a Korean native herb, has been a symbol of mystic cure-all which provides longevity benefits throughout Korean history. According to Chinese historical records, a major source of wild ginseng has been described as Korean peninsula, which is the most suitable ginseng production area, and the Manchu region near Mt. Baekdu and the Maritime Province. Since Tang dynasty period (618-917 CE), Chinese has also called ginseng as "Goryeo Ginseng", which is named after "Goguryeo" (37 BCE-668 CE), an ancient kingdom of Korea, from which they mainly imported the herb as the region was famous for its high quality of ginseng. To date, it refers to Korean ginseng. This study compares the medicinal properties of ginseng as stated in the ancient Korean medical books with the major Korean historical records regarding the usage of ginseng and its symbolism of longevity in everyday life. By contrasting these findings, we tried to figure out how the actual medicinal properties of ginseng and the anticipation of longevity are related. It was confirmed that the expectations about longevity were widely applied to everyday life. In addition, the study investigates the various usage of ginseng as a motive for decorative patterns and as an ingredient for daily products including snacks, health drinks, various types of food, clothing patterns, and so on. Finally, the usage of ginseng ingredients in the cosmetic products fulfilled the desire of Korean people to purchase, showing the aesthetic recognition and medicinal understandings about the herb. These findings suggest that ginseng is an important medicinal agent that not only symbolizes longevity and good health but also has a great influence on the lives of Koreans.

Nondestructive inspection and accompanying life analysis based on fracture mechanics were the major conventional methods for evaluating remaining life of critical high temperature components in power plants. By using these conventional methods, it has been difficult to perform in-service inspection for life prediction. Also, quantitative damage evaluation due to unexpected abrupt changes in operating temperature was almost impossible. Thus, many efforts have been made for evaluating remaining life during operation of the plants and predicting real-time life usage values based on the shape of structures, operating history, and material properties. In this study, a core software for on-line life monitoring system which carries out real-time life evaluation of a critical component in power boiler(high temperature steam headers) is developed. The software is capable of evaluating creep and fatigue life usage from the real-time stress data calculated by using temperature/stress transfer Green functions derived for the specific headers and by counting transient cycles. The major benefits of the developed software lie in determining future operating schedule, inspection interval, and replacement plan by monitoring real-time life usage based on prior operating history.
