With the development of broadcasting technology from analogue to interactive digital, the number of TV channels and TV contents provided to audiences is increasing in a rapid speed. In this multi-channel world, it is difficult to adapt to the increase of the TV channel numbers and their contents merely using remote controller to search channels. For these reasons, the EPG system, one of the essential services providing convenience to audiences, is proposed in this paper. Collaborative filtering method with multi-step filtering is used in EPG to recommend contents according to the preference of audience groups with similar preference. To implement our designed TV contents recommendation EPG, we prefer DiTV and use JavaXlet programming based on MHP. The European DVB-MHP specification will be also our domestic standard in DiTV. Finally, the result is verified by OpenMHP emulator.

Life cycle costing is one of the most effective approaches for the cost analysis of long-life products such as the railroad vehicle. Life cycle costing includes the cost of concept design, development, manufacture, operation, maintenance and disposal. Especially, life cycle costing in the railroad industry has been focused on the maintenance cost. In this paper, the standard, guide and maintenance information of railroad vehicle were investigated, and the unique corrective and preventive maintenance templates of railroad vehicle were proposed. Maintenance cost of an auxiliary power supply system of EMU was predicted by using the proposed templates. The results show that the preventive maintenance, PM, cost is much higher compare to corrective maintenance, CM, cost because of daily and monthly maintenance tasks which require lots of labor work. It is expected that these templates can help railroad operators make maintenance strategies with consideration of the cost parameter.

A dentigerous cyst is an epithelium-lined sac that surrounds the crown of an unerupted tooth or odontoma. And the most common sites of this cyst are the mandibular and maxillary third molar and maxillary cuspid a areas. Clinically, expansion of bone with subsequent facial asymmetry, extreme displacement of teeth, severe root resorption of adjacent teeth and pain are all possible sequelae of this cyst. The standard treatment for a dentigerous cyst is enucleation and extraction of the involved tooth. But in large cysts, this can lead to functional, cosmetic and psychologic consequences to the patients. So recently, more conservative methods are used. We report 5 cases of dentigerous cysts in pediatric patient which were treated by a conservative approach, By this methods, we can preserve teeth and guide eruption of the teeth which are involved in cystic area.

The purpose of this study is to guide the research direction for securing the competitiveness of the textile industry by analyzing the trends of patent technology development for flexible materials and platform technologies of domestic and overseas textiles used for wearable devices. The study is based on patents from Korea (KIPO), USA (USPTO), Japan (JPO), Europe (EPO), PCT (WO), and China (SIPO), which were registered as of December 31, 2017. The analysis utilized 3,643 patents acquired from the WINTELIPS search DB. The technology classification system for patent analysis was divided into evangelist-based textile technology developments: human body (AA), fiber attachment patch development (AB), and service platform development (AC). The analysis findings are as follows: 1. The development of flexible materials and platform technologies for textile-based wearable devices has increased since 2000. In particular, China (SIPO) had the most patents. 2. In China, Japan, and Korea, most patent applicants are applied for by natives, but the US has a high proportion of foreigners applying for patents. 3. As for the amount of development of the evangelist-based textile technology (AA) was the most common with 1,203 (33%) cases. As a result of the above IP historical analysis, it can be seen that as a result of the global competition, domestic companies need to acquire IRP and standard technology, and promote commercialization by applying their products to smart wearables devices and other products.

Recently, as evaluation of information security (IS) management become more diverse and complicated, the contents and procedure of the evidence to prepare for actual assessment are rapidly increasing. As a result, the actual assessment is a burden for both evaluation agencies and institutions receiving assessments. However, most of them reflect the evaluation system used by foreign government agencies, standard organizations, and commercial companies. It is necessary to consider the evaluation system suitable for the domestic environment instead of reflecting the overseas evaluation system as it is. The purpose of this study is as follows. First, we will present the problems of the existing information security assessment system and the improvement direction of the information security assessment system through analysis of existing information security assessment system. Second, it analyzes the technical guidance for information security testing and assessment and the evaluation of information security management in the Special Publication 800-115 'Technical Guide to Information Security Testing and Assessment' of the National Institute of Standards and Technology (NIST). Third, we will build a framework to implement the evidence collection system and present a system implementation method for the '6. Information System Security' of 'information security management actual condition evaluation index'. The implications of the framework development through this study are as follows. It can be expected that the security status of the enterprises will be improved by constructing the evidence collection system that can collect the collected evidence from the existing situation assessment. In addition, it is possible to systematically assess the actual status of information security through the establishment of the evidence collection system and to improve the efficiency of the evaluation. Therefore, the management system for evaluating the actual situation can reduce the work burden and improve the efficiency of evaluation.

Since the specifications of public services in broadcasting-telecommunication convergence environment are not standardized, the public services should be developed and presented by each IPTV service provider, and therefore it is worried that public organizations and IPTV service providers may invest in the public services redundantly, which are managed inefficiently. To resolve those problem, in this paper, the service and network interfaces among multiple public organizations and multiple IPTV service providers and the interactive VOD-type public service providing system of one source multi-use based on ACAP-J are proposed. The proposed system can be utilized in the standard platform of the evolved new public services. And the used technologies can be utilized as a guide for the development of new services.

Analysis of the 2016 Gyeongju earthquake and the 2017 Pohang earthquake showed the characteristics of a typical high-frequency earthquake with many high-frequency components, short time strong motion duration, and large peak ground acceleration relative to the magnitude of the earthquake. Domestic nuclear power plants were designed and evaluated based on NRC's Regulatory Guide 1.60 design response spectrum, which had a great deal of energy in the low-frequency range. Therefore, nuclear power plants should carry out seismic verification and seismic performance evaluation of systems, structures, and components by reflecting the domestic characteristics of earthquakes. In this study, high-frequency amplification factors that can be used for seismic verification and seismic performance evaluation of nuclear power plant systems, structures, and equipment were analyzed. In order to analyze the high-frequency amplification factor, five sets of seismic time history were generated, which were matched with the uniform hazard response spectrum to reflect the characteristics of domestic earthquake motion. The nuclear power plant was subjected to seismic analysis for the construction of the Korean standard nuclear power plant, OPR1000, which is a reactor building, an auxiliary building assembly, a component cooling water heat exchanger building, and an essential service water building. Based on the results of the seismic analysis, a high-frequency amplification factor was derived upon the calculation of the floor response spectrum of the important locations of nuclear power plants. The high-frequency amplification factor can be effectively used for the seismic verification and seismic performance evaluation of electric equipment which are sensitive to high-frequency earthquakes.

Since the first dietitian was produced in Korean about 15 years ago the Korena Dietetic Association has grown up to have its 8,500 members as of March, 1979. This study was undertaken to survey the status of hospital dietitians and their bob analysis. current practices were learned and the problems identified mainly in such aspects as : 1. Do the hospitals have enough dietitians? 2.What is the administrative position of the dietetics in the hospital? 3. What is the salary level of the dietitians? 4. How professional are the dietitian's daily tasks? How appropriately are the jobs distributed among the dietary employees? and 5. Do the hospital dietetics have their own diet manuals to go by? The findings are : 1. The severly lacking number of dietitians are employed by the hospitals where one dietitian is responsible for the feeding and nutrition education of 171 in-patients on the average. 2. The administrative position of hospital dietetics appears to be low showing administrative position of hospital dietetics appears to be low showing only 45.7% of the sample hospitals recognize their dietetics as the independent department or section. 3. The starting salary of the 4-year college graduate dietitians is 151,450 won which is 89.23-87.26% of the average starting salary for the 4-year college graduates I 1979. The starting salary for the 4-year college graduates in 1979. the starting salary of the 2-year college graduate dietitians is 148,000 won which is 113.9% of the average standard salary for the 2-year college graduates in 1979. 4. The hospital dietitians spend most of their time doing clerical jobs rather than the jobs utilizing higher priority professional skills they ought to perform. the most obvious cause of the problem can be found in the lack of man power for the general clerical jobs in the dietetics which can be proven from the small number of dietary clerks hired by the sample hospitals not even one person (0.45) per hospital on the average. 5. 68.6% of the sample dietetics have some form of compiled diet manuals or guidelines. 11.4% of the samples have diet guide lines ready for the important diets only. 14.3% of the samples do not have any form of diet guideline prepared. 5.7% of the samples use reference diet manuals from other hospitals when need.
