With the recent global urban issues such as climate change, urbanization, and energy problems, the smart city was proposed as one of the solutions in urban planning. This study introduces the smart city initiatives of South Korea by examining the recent history of smart city policies and their limitations. This case study reflects the experience of one of the countries which thrived to building smart cities as their national key industries to drive economic growth. It also analyzes the trends of the smart city using big data analysis techniques. Although there are obstacles such as economic recession, failing to differentiate from the U-city, low service level than expected smart functionality, We could recognize the current status of the smart city policies in South Korea such as 1) Korean smart city development projects are actively implemented, 2) public consensus suggests that applying advanced technology and the active role of government need, 3) a comprehensive and strategic approach with the integration and application of advanced technologies is required as well, 4) investment by both private and public sectors need to deliver social improvements. This study suggests future direction of smart city polity in South Korea in the conclusion.

With the rapid development of e-commerce, many customers can now express their opinion on various kinds of product at discussion groups, merchant sites, social networks, etc. Discerning a consensus opinion about a product sold online is difficult due to more and more reviews become available on the internet. Opinion Mining, also known as Sentiment analysis, is the task of automatically detecting and understanding the sentimental expressions about a product from customer textual reviews. Recently, researchers have proposed various approaches for evaluation in sentiment mining by applying several techniques for document, sentence and aspect level. Aspect-based sentiment analysis is getting widely interesting of researchers; however, more complex algorithms are needed to address this issue precisely with larger corpora. This paper introduces an approach of knowledge representation for the task of analyzing product aspect rating. We focus on how to form the nature of sentiment representation from textual opinion by utilizing the representation learning methods which include word embedding and compositional vector models. Our experiment is performed on a dataset of reviews from electronic domain and the obtained result show that the proposed system achieved outstanding methods in previous studies.

We have identified the paradigm, the knowledge structure, and the roles of S&T policy studies in Korea by empirical analysis and focus group interviews. First, it provisionally concluded that S&T policy studies in Korea are still in the pre-paradigm stage. Specifically, the level of consensus among scholars about the "academic definition of discipline" and "research scope", which is essential for an independent discipline, is still low. Next, a great part of the existing S&T policy studies in Korea is excessively weighted in specific research scopes and researcher groups. For a balanced development as an academic discipline, such imbalance must be overcome. Third, the studies in Korea showed that much of the research in the earlier stage was fragmented at the micro-level. More recently, however, S&T policy studies show co-evolutionary patterns, which increase the responsiveness of the society. Based on this analysis, the future direction of studies should form a unique flow of our own, building Korean policy cases and models rather than following those developed countries.

Molecular modeling study has been performed to assist in the design of PTP1B inhibitors using FlexX. FlexX dockings with 19 test ligands, whose structures have been determined by X-ray crystallography, were successful in reproducing the experimental conformations within the protein. An increase in biological activity is observed as hydrophobic character of formylchromone derivatives increases. Most ligands bind to the activesite regions of the protein successfully in two different score runs. The Drug score run gave better results than the FlexX score run based on the score, rank, binding modes and bond distance of docked structures. Consensus values from the CScore scoring function are between 3 and 5, suggesting that the scoring scheme is reliable. All formylchromone inhibitors considered in this work show unidirectional binding modes in the active site pocket, which is contrary to the bidirectional X-ray results by Malamas et al. and amino acid residues responsible for such orientation are identified to help further development of the inhibitors.

During the past decade, many studies using platelet-rich plasma (PRP) or adipose-derived stem cells (ASCs) have been conducted in various medical fields, from cardiovascular research to applications for corneal diseases. Nonetheless, there are several limitations of practical applications of PRP and ASCs. Most reports of PRP are anecdotal and few include controls to determine the specific role of PRP. There is little consensus regarding PRP production and characterization. Some have reported the development of an antibody to bovine thrombin, which was the initiator of platelet activation. In the case of ASCs, good manufacturing practices are needed for the production of clinical-grade human stem cells, and in vitro expansion of ASCs requires approval of the Korea Food and Drug Administration, such that considerable expense and time are required. Additionally, some have reported that ASCs could have a potential risk of transformation to malignant cells. Therefore, the authors tried to investigate the latest research on the efficacy and safety of PRP and ASCs and report on the current state and regulation of these stem cell-based therapies.

The objectives of this study is to examine the German mandatory prescription system in terms of the applicability and restriction of the pharmaceutical policy in order to obtain some useful implications for solving the problems in Korean prescription system. Recently, in Germany, an issue about the security of the prescription, the price control of the pharmaceuticals and the containment of the increasing prescription expenditure has been intensively discussed. Similar problems are also occurred in Korea. So, the policy measurements of Germany could be used in Korea. But it could not easy to introduce the German policy measurements in Korea because of the social-institutional differences between the two countries, which are following; (1) Korea has a short experience with the mandatory prescription system, (2) the German concept of the management differs from that of the Korea, (3) the subscribers and the patients are excluded from the decision making process, (4) the medical service providers often resist against reform plans. For the stable development of the Korean prescription system the principle of self-government, the collective bargaining concept for cost containment, and social consensus about optimal expenditure of the pharmaceuticals are expected to be needed.
