Moon Jae-in Government announced the Government's 5-Year Plan on July 19, 2017, President Moon directly announced the Government's Plan for Benefit Expansion in National Health Insurance on August 7, 2017. The main contents of the announced expansion include benefit coverage for all medically necessary services with control over non-covered service occurrence, a decrease in the cost-sharing upper limit, and monetary support for catastrophic medical costs. Although past governments have been continuously striving for benefit expansion in the last 15 years, this plan has its breakthrough aspect in that all medical services will be covered by the National Health Insurance. In alignment, there are important tasks to solve: attaining a proper fee schedule, reforming the healthcare delivery system, and improving healthcare quality. This plan is a symptom oriented action in that it is limited in reducing patients' out-of-pocket money, unlike the systematic approach of the National Health Insurance. The sustainability of the National Health Insurance is being threatened due to South Korea's low birth rate, rapidly aging society, and low economic growth, in addition to the unification issue of the Korean Peninsula, medical utilization of the elderly, management of non-communicable diseases, and so on. Therefore, the Government needs to plan the National Health Insurance system reformation including actions addressed toward medical consumers.

In Mo-Xwt%Cu compound, Physical and thermal properties were systematically evaluated in terms of Cu contents and sintering temperature. Typically Cu contents were varied from 15 to 25wt% and also the Sintering temperatures were changed from $1115^{\circ}C$ to $1350^{\circ}C$. In physical properties, Mo-15~25wt%Cu has the maximum density of 95% while Mo-20wt%Cu has the maximum thermal conductivity of 165.179[${\mu}/m^{\circ}C$] at sintering temperature of $1300^{\circ}C$. Especially, Mo-25wt%Cu has the maximum hardness of 173.4 at sintering temperature of $1150^{\circ}C$ and the maximum thermal expansion of 9.0[W/mK] as the specimen heated in the range of temperature from $50^{\circ}C$ to $400^{\circ}C$. Based on electrical conductivity measurements, the relative density increased within creasing Cu contents and the values were in the range of 100~150[W/mK].

Online service has been emphasized in various studies for content uses and diffusion of cultural heritage domain. This study purports to investigate the status of contents organization and information services for online cultural heritage services and to suggest improvement directions. This study conducted case studies and expert interviews based on contents, search systems, additional services, and expansion services. It also suggested an integrated information retrieval service for cultural heritage contents as well as the provision of high-quality content and various types of contents. The flexibility of the search function through the content hierarchy, the expansion of access points through the construction of controlled vocabulary, and authority data were also focused. As an additional service, the study proposed a curation-based, user-customized service, data sets open and share, and user participation.

As OTT services become popular worldwide, content IP expansion strategy has an important position in the platform media industry ecosystem where new content is constantly distributed. In particular, the method in which a successful narrative expands the elements constituting a specific world, that is, the Universe, is effective in reducing risk factors in content IP expansion and expanding content franchises. This study intends to examine how Marvel's cinematic Universe (MCU) is strategically performing content IP expansion while borrowing the multiverse concept and replicating and reproducing it by itself through narrative analysis of . As a result, the multiverse can reproduce an incomplete state by repeating the completed event, which can exist as another self-fulfilling content. At the same time, it can be an effective content IP expansion strategy in that each story can be produced because a single character can exist in multiple under the multiverse.

This study was performed to proof expansion effect of the mortar bar due to Alkali-silica Reaction (ASR) by ASTM C 1260 test. Recently, the failure case of cement concrete pavement by ASR was reported in Korea. Cement concrete structures are caused crack by ASR. The service life of cracked cement concrete structures by ASR will be shorted. In this study, crushed the slate rock producted Chungcheongnamdo Boryeong was caused 0.3% expansion at 14 days due to ASR by ASTM C 1260 test. The particular spectrum showed that the ASR gel was analyzed contents included Si, Na, K, and Ca by EDX (electron dispersive X-ray spectrometer). It was verified that the crushed aggregate was caused expansion by ASR in Korea.

The remarkable growth of the Internet since mid-l990s has expanded the e-learning market and brought the transformation of educational environments and methodology. It can be said that the e-learning has changed the educational paradigm. Korean government is firmly determined to support the diffusion of e-learning because of the benefits of e-learning. People seem to accept the e-learning when its contents have high quality. A lot of research have been conducted on e-learning, however, it was mostly about user's usage intention, satisfaction and educational effect. It can't seem that sufficient research efforts have been put into figuring out the role of e-learning contents quality in the expansion of e-learning. In this paper, we present the empirical study on the influence of e-learning contents quality on user's satisfaction and educational effect. We conducted an questionnaire survey on college students to collect data and found that the quality of e-learning contents has significant influence on the users' satisfaction.

In this study, contents of 'the 2007 revised curriculum handbook' and 16 kinds of mathematics textbooks were analyzed first. The purpose of this study is to examine the understanding state of students at general high schools by making questionnaires to survey the understanding state on contents of chapter of complex number based on above analysis. Results of research can be summarized as follows. First, the content of chapter of complex number in textbook was not logically organized. In the introduction of imaginary number unit, two kinds of marks were presented without any reason and it has led to two kinds of notation of negative square root. There was no explanation of difference between delimiter symbol and operator symbol at all. The concepts were presented as definition without logical explanations. Second, students who learned with textbook in which problems were pointed out above did not have concept of complex number for granted, and recognized it as expansion of operation of set of real numbers. It meant that they were confused of operation of complex numbers and did not form the image about number system itself of complex number. Implications from this study can be obtained as follows. First, as we came over to the 7th curriculum, the contents of chapter of complex number were too abbreviated to have the logical configuration of chapter in order to remove the burden for learning. Therefore, the quantitative expansion and logical configuration fit to the level for high school students corresponding to the formal operating stage are required for correct configuration of contents of chapter. Second, teachers realize the importance of chapter of complex number and reconstruct the contents of chapter to let students think conceptually and logically.

High-strength low-alloy steel is one of the widely used materials in onshore and offshore plant engineering. We investigated the alloying effect of solute atoms in α-Fe based alloy using ab initio calculations. Empirical equations were used to establish the effect of alloying on the Vicker's hardness, screw energy coefficient, and edge dislocation energy coefficient of the steel. Screw and edge energy coefficients were improved by the addition of V and Cr solute atoms. In addition, the addition of trace quantities of V, Cr, and Mn enhanced abrasion resistance. Solute atoms and contents with excellent mechanical properties were selected and their thermal conductivity and thermal expansion behavior were investigated. The addition of Cr atom is expected to form alloys with low thermal conductivity and thermal expansion coefficient. This study provides a better understanding of the state-of-the-art research in low-alloy steel and can be used to guide researchers to explore and develop α-Fe based alloys with improved properties, that can be fabricated in smart and cost-effective manners.

Korean is free of omission of sentence elements and modifying scope, so managing it on morphological analyzer is better than parser. In this paper, we propose functional expansion methods of the morphological analyzer to ease the burden of parsing. This method is a longest phrase matching method. When the series of several morpheme have one syntax category by processing of Unknown-words, Compound verbs, Compound nouns, Numbers and Symbols, our method combines them into a syntactic unit. And then, it is to treat by giving them a semantic features as syntax unit. The proposed morphological analysis method removes unnecessary morphological ambiguities and deceases results of morphological analysis, so improves accuracy of tagger and parser. By empirical results, we found that our method deceases 73.4% of Parsing tree and 52.4% of parsing time on average.
