As new types of medical devices are emerging through convergence with advanced technology, innovative technologies are becoming hot issues in health policy because of their disruptiveness. This study analyzed the innovative medical device management systems in the US, China and Korea. Innovative medical devices have been defined differently depending on the country's management system, but in common, they are defined as products that do not exist or have dramatically improved performance compare to existing products by applying innovative technologies. Innovative medical devices have been supported by regulatory authorities during product development and approval processes. While the US and China have more than 300 products designated as innovative medical devices with diverse functions, application fields, and manufacturing countries considering the initial situation of the implementation for the system, Korea has only 16 products, mainly radiology and diagnostic devices and made in Korea only as innovative medical device. In addition, Korea shows the highest market approval rate of innovative medical devices compare to the US and China, and it is necessary to prepare the approval process in consideration of product diversity.

Big data has recently been used in various industries such as tourism, medical care, distribution, and marketing. And it is evolving to the stage of collecting real-time information or analyzing correlations and predicting the future. In the tourism industry, big data can be used to identify the size and shape of the tourism market, and by building and utilizing a large-capacity database, it is possible to establish an efficient marketing strategy and provide customized tourism services for tourists. This paper has begun with anticipation of the effects that would occur when big data is actively used in the tourism field. Because the method of use must have applicability and practicality, the spatial scope will be limited to Seosan, Chungcheongnam-do, and research will be conducted. In this paper, to improve the quality of tourism courses by collecting and analyzing the number of mention data and sentiment index data on social media, which reflect the tourist's interest, preference and satisfaction. Therefore, it is used as basic data necessary for the development of new local tourism courses in the future. In addition, the development of tourism courses will be able to promote tourism growth and also revitalizing the local economy.

As there has been growing interests in PHR-based personalized health management project, various institutions recently explore safe methods of recording personal medical and health information. In particular, innovative medical solution can be realized when medical researchers and medical service institutes can generally get access to patient data. As EMR data is extremely sensitive, there has been no progress in clinical information exchange. Moreover, patients cannot get access to their own health data and exchange it with researchers or service institutions. It can be operated in terms of technology, yet policy environment are affected by state laws as well as Privacy and Security Policy. Blockchain technology-independent, in transaction, and under test-is introduced in the medical industry in order to settle these problems. In other words, medical organizations can grant preliminary approval on patient information exchange by using the safely encrypted and distributed Blockchain ledger and can be managed independently and completely by individuals. More apparently, medical researchers can gain access to information, thereby contributing to the scientific advance in rare diseases or minor groups in the world. In this paper, we focused on how to manage personal medical information and its protective use and proposes medical treatment exchange system for patients based on a permissioned Blockchain network for the safe PHR operation. Trusted Model for Sharing Medical Data (TMSMD), that is proposed model, is based on exchanging information as patients rely on hospitals as well as among hospitals. And introduce medical treatment exchange system for patients based on a permissioned Blockchain network. This system is a model that encrypts and records patients' medical information by using this permissioned Blockchain and further enhances the security due to its restricted counterfeit. This provides service to share medical information uploaded on the permissioned Blockchain to approved users through role-based access control. In addition, this paper presents methods with smart contracts if medical institutions request patient information complying with domestic laws by using the distributed Blockchain ledger and eventually granting preliminary approval for sharing information. This service will provide an independent information transaction and the Blockchain technology under test will be adopted in the medical industry.

We utilized terahertz time-domain spectroscopy (THz-TDS) to measure the thickness and electrical properties of nickel-chromium (Ni-Cr) films. This technique not only aligns well with traditional methods, such as haze-meter and transmission-densitometer measurements, but it also reveals the electrical properties and thickness of films down to a few tens of nanometers. The complex conductivity of the Ni-Cr thin films was extracted using the Tinkham formula. The experimental values closely aligned with the Drude model, indicating the reliability of our Ni-Cr film's electrical and optical constants. The thickness of Ni-Cr was estimated using the complex conductivity. These findings emphasize the potential of THz-TDS in quality control of metallic nanofilms, pointing toward an efficient and nondestructive test (NDT) for such analyses.

한국의 의료기기 산업은 1995년부터 시작된 G7 의료공학기술개발사업으로 본격적인 성장과 발전의 기틀을 마련하였으며 2020년 한국 의료기기 생산실적은 2001년에 비하여 8.52배, 수출 실적은 13.94배 성장하였다. 의료기기 국산화 개발 초기에 초음파 의료기기 등 전자 의료기기의 개발이 활발하였던 것과 비교하여 2020년에는 체외진단시약과 치과용 임플랜트의 생산 및 수출 실적이 상위권을 차지하고 있다. 그러나 한국 의료기기 시장에서 수입 의료기기가 차지하는 비중은 60-70%에서 큰 변화가 없는데 이는 한국의 의료기기 산업이 중저가 의료기기를 생산 수출하고, 기술집약적이고 자본집약적인 고가 의료기기는 주로 수입에 의존하고 있기 때문이다. 본 논문에서는 한국과 세계시장의 주요 의료기기 회사들의 생산 품목을 비교하여 한국 의료기기 산업의 세계 시장 진출에 대한 전략을 제시하고자 한다.

With the development of medical technology, interest in rehabilitation devices is increasing and various devices are being studied. In particular, devices for speech disorders such as hearing impairment and cleft palate are attracting attention. In general, the nasometer is used for patients with flaccid dysarthria and velopharyngeal incompetence(VPI). However, in the case of the conventional separator type nasometer, that has an acoustic feedback problem between the oral and nasal sounds. In recent, the mask type nasometer has been developed which is insensitive to acoustic feedback. But, still not popularized. In this paper, the nasometer characteristics of the conventional separation type and mask type are analyzed. Also, We were obtained clinical acoustic data from the 6 subjects and examined the significant differences in the structure of the separation type and mask type nasometer. Through experiments, it was confirmed that the measurement was about 3~15% higher in the mask type nasometer than the conventional nasometer having a separator type. Also, We was considered the necessity of nasometer signal processing for acoustic feedback reduction and nasalance calculation optimization.
