이동통신사 주도의 LPWA(Low Power Wide Area) 기반 IoT 기술은 NB-IoT와 LTE Cat.M1이 상용화되어 서비스되고 있다. LPWA 기반 IoT에 대한 서비스 요구사항이 증가되면서 이러한 서비스 가입자도 증가하고 있는 상황이다. 서비스 초기에는 NB-IoT 및 LTE Cat.M1을 수용하기 위한 기지국 용량에 이슈가 없었으나, 가입자 증가로 하나의 셀에서 수용하기 위한 용량이 부족해지는 문제가 발생하고 있다. 이러한 Active UE 용량 문제는 지속적인 증가로 인한 과부하와 일시적인 증가로 인한 과부하 문제가 발생할 수 있다. 본 논문에서는 기지국에서 NB-IoT 및 LTE Cat.M1 단말의 일시적인 증가로 인해 발생 하는 LTE 접속제어 채널인 RRC(Radio Resource Control) Active UE 용량 부족 및 기지국 과부하 문제를 해결하기 위한 방안을 제시한다. 제시한 방안은 이동통신의 셀 분할 및 추가 기지국 투자 없이 셀 용량을 증대 시킬 수 있는 방안을 제시함으로써, 증가하는 IoT 단말을 수용해 서비스 성능을 개선시킨다.

This study aims to develop strategies to reinforce the roles of universities and volunteer service activities centering on promotion of their connections to communities and community-oriented volunteer service activities. First, for autonomous and continuing development of volunteer services, universities should have active connections with service organizations. Second, more specialized volunteer service programs should be developed. Third, as volunteer service activities are somewhat forced on college students, recognition for them should be improved. Fourth, as the quality of the service and academic achievement decrease, conditions for volunteer service education and programs should be made available. Fifth, for continuing participation in volunteer service activities, organized systems should be established.

The basic point of a vehicle recall is to remove vehicle defects as soon as possible and thus prevent possible road traffic accidents caused by the defects beforehand. Therefore, the core of vehicle recall under the self-certification system consists of a timely response and fast remedy of defects. The present study aimed to deduce a plan for improvement of the system necessary for the fast remedy of defects through a phased analysis of defect investigation procedure based on defect investigation statistical data. There will be a need to make the TSB(Technical Service Bulletin) or service campaign data submission of a manufacturer compulsory for the collection of broad defect information in the stage of information analysis and to impose a higher penalty when the manufacturer violates the data submission in the investigation stage. In addition, it is considered that an active service campaign should be induced and a punishment for late recall will be needed for consumer protection.

Recently, a wide variety of research on the knowledge-based industries, which are considered a key area of social science research, has been conducted. In this light, this study examines a case of knowledge diffusion taken from the IT service field. The IT service industry has been considered difficult to diffuse due to its unique technological regimes and sophisticated market demand. In particular, the established public service systems have limited markets and encompass national characteristics, thereby making their international diffusion difficult. However, despite these limitations, the automated customs system ASYCUDA has been distributed successfully and is now operating in about 100 countries, making the case very unusual. Using various industrial innovation models, and an analysis of lead markets, with regard to ASYCUDA, this research examines patterns of technological learning activities by actors, characteristics of the lead markets, and paths of technology transfer. The findings indicate that when active technology providers attempt to streamline and standardize the technology to make it suitable for the characteristics of the initial technology application areas(lead markets), this helps to diffuse the technology to passive recipients and the surrounding nations. The findings also confirm that south-south cooperation in the acquired technologies was of considerable help in sharing knowledge among the passive technology recipients, and that the active technology providers' programmed, well-organized technology assistance was a key driving force behind technology transfer and diffusion between the surrounding nations.

Purpose: This study aimed to examine the necessity of administrative compensation insurance and claims cases during the emergency medical service process among administrative compensation insurance cases and suggests problems and improvement measures. Methods: We compared the details of administrative compensation insurance claims of 15 cities and provinces, excluding Seoul and Kwangju, from 2017 to 2020 by requesting details disclosure of the comprehensive deduction for administrative compensation in 17 cities and provinces across the country. Results: A total of 69 cases were compensated through the administrative comprehensive compensation deductions. There were 53 cases of damage that occurred at the field stage, 14 cases at the transfer and hospital stage, and two other cases. Conclusion: The 119 paramedics, which are the perpetrators, should be active in field activities and free from the psychological pressure caused by increased workload and litigation. Active compensation administration is required for damage cases occurring in the firefighting activities context.

A number of toxicants have been incriminated as a causing hepatic disease. Among many detrimental injury, alcohol has been noted for hepatitis, fatty liver, fibrosis, and hepatic cirrhosis. The purpose of this study was to develop animal model for hepatic fibrosis in pigs fed ethanol, and to search for a new anti-fibrogenic agent via this model. Twelve male Landrace pigs were divided into 3 groups of 4 animals each. Group 1, 2 and 3 were fed with active ceramic water only, ceramic water + liquid diet containing 15% ethanol and normal tap water + liquid diet containing 15% ethanol for 12 weeks, respectively. At week 12, all pigs were immediately sacrificed for collection each tissue and blood. Serologically, serum ALT and AST levels were significantly reversed in group 2, as compared to group 3. They were normal range in pigs of group 1. Microscopically, macrovesicular lipid droplets and moderate hepatocellular necrosis were evident in the tap water + ethanol fed group 3. However, the active ceramic water treated group 1 showed normal architecture. Moreover, in group 2, mild fatty changes and necrosis were observed in hepatocytes. Collagen fibers were increased in spaces surrounding periportal and interlobular connective tissues in the group 3 of tap water + ethanol, but collagen synthesis and its thickness of fibrotic septa connecting portal tracts were markedly reduced in the group 2 of ceramic water + ethanol. Myofibroblasts were detected mainly in the interlobular connective tissues of pig liver of group 3 treated ethanol and tap water. Few to no myofibroblasts were observed in groups 1 and 2. CYP2E1 was not or rarely detected in group 1 fed ceramic water. However, group 2 showed slightly activation of CYP2E1 in the area of pericentral vein, while CYP2E1 was significantly activated in group 3 fed tap water and ethanol. Based on the above data, we believe that we have developed a unique alcohol induced fibrosis model in pig, which will be useful in developing anti-fibrotic agents and drugs. Furthermore, the active ceramic water used in our study had an inhibitory and may be protective against ethanol induced hepatic toxicity and fibrosis.

Open Decision Support System(DSS) is an automated and transparent system that is built to be shared both within and across organizations. The open DSS has been thought to be a set of decision components that are communicating through Web protocols. These characteristics intuitively invite the Web services concepts, which are currently one of the new trends in network-based business services. However, web services still are not active enough to be autonomous, and to provide for composing functionalities. These lead to the motivation on building a sophisticated web service to contain these features and to utilize web services on behalf of the user. This paper aims to propose a new concept of Meta Web Service, a web service-based open DSS. Decision modules in a dynamic and open DSS can be viewed as a web service. The Meta Web Service understands the users problem statement with ontology, performs web service discovery, web service composition, and automatically generates codes for composite web service execution. A prototype of example web service has been developed to show the feasibility of the proposed idea.
