This paper discusses service discoveries for smart trusted reality (TR) glass and networks developed by the Electronics and Telecommunications Research Institute. TR glass provides a differentiated gaze communication service from the well-known AR glass. Services include on-off of products that reach the eye, encryption of courier addresses, and time-based networking services. This paper addresses the technical roots and service scalability of TR glass. Furthermore, the agricultural sector was selected to provide microservices configuration, connectivity with 5G communication, and a full range of applications for extended services.

Information services adopting RSS(Really Simple Syndication) is on an increase. It is replacing the existing email services. Information in the area of science and technology is of vast amount and various area and their life-cycle and service is complex. Institutions providing information of a single area are not faced with many obstacles in designing information services using RSS in acquiring a channel for the service. However, RSS service in the area of science and technology has to be more specific in designing and implementing the services. In this study, RSS is compared with other information service protocols, domestic and international trends in the area of RSS is analyzed to implement the RSS based Science and Technology information service system(STI-RSS) and its service.

Recently, there have been the increase of ship size and the development of oil and gas in arctic region. These trends have led to the requirements such as high strength, good toughness at low temperature and good weldability for prevent of brittle fracture at service temperature. There has been the key issue of crack arrestability in large size structure such as container ship. In this report for the first time, crack arrest toughness of thick steel plate welds was evaluated by large scale ESSO test for estimate of brittle crack arrestability in thick steel plate. For large structures using thick steel plates, fracture toughness of welded joint is an important factor to obtain structural integrity. In general, there are two kinds of design concepts based on fracture toughness: crack initiation and crack arrest. So far, when steel structures such as buildings, bridges and ships were manufactured using thick steel plates (max. 80~100mm in thickness), they had to be designed in order to avoid crack initiation, especially in welded joint. However, crack arrest design has been considered as a second line of defense and applied to limited industries like pipelines and nuclear power plants. Although welded joint is the weakest part to brittle fracture, there are few results to investigate crack arrest toughness of welded joint. In this study, brittle crack arrest designs were developed for hatch side coaming of large container ships using arrest weld, hole, and insert technology.

The aim of this study was to understand how the employee satisfaction effect to their turnover trends through the survey on the employee satisfaction and the turnover trend in the pastry and bakery department on the objection of the employee of the bakers of the luxurious hotels in Seoul area. The study was selected to study the luxurious hotels located in Seoul area and make the objection of the employee in the pastry and bakery kitchen. As the contents of the assumption of the study, the independent variable was ' the pastry and bakery employee's organizational factor ', and the dependant variables were ' job satisfaction of the pastry and bakery employee ', ' turnover trends of the pastry and bakery employee ' and implicates the comparison and the mutual relationship between variables to shows the confirmation of them. As the measurement tools, it adopted the reliability analysis, the technical statistics analysis, the frequency analysis, cross-section analysis and on the verification of the assumption, it was used linear regression analysis. The result of the study showed that the satisfaction degree toward the work schedule showed to be as the personal elements while the systematic organizational establishment and the management policy, the work capacity and the job placement, the cooperation with other parts and the operation of the work time showed to be as the organizational elements. The job satisfaction elements showed as the satisfaction on the system and the rule of the job, the satisfaction on the right and belonging, the satisfaction on the achievement and the communication. As regarded to the job turnover, the turnover intention concerned the opportunity, disappointment of assignment, general complaint, and work condition. Those were shown to be elements of the job satisfaction and the turnover of the employee. And also, that were necessary to manage the job satisfaction and the turnover of the employee concerning these factors.

The altitude compensation nozzle is a nozzle designed for optimum performance at all altitudes. A method of improving the specific impulse of the space launch vehicle is a method of improving the characteristic exhaust velocity which is a characteristic of the combustion chamber and a method of improving the thrust coefficient which is a characteristic of the nozzle. The altitude compensation nozzle enables improvement of the performance of the space launch vehicle by improving the nozzle performance for the same combustor. Research on altitude compensation nozzles has been actively carried out in the DLR in Germany and is being carried out in advanced countries such as the US, Russia, UK, Australia and Japan. In this paper, the technology trends and patent trends of altitude compensation nozzles are investigated and summarized. Based on this, the technical trends of altitude compensation nozzles is grasped and utilized as basic data for the study on the performance improvement of a launch vehicle.
