In 2003, the Uniform Commercial Code(UCC) which is a kind of model law to unify commercial law between several states in US was amended to use electronic document of title including bill of lading. It is the second following the Australia legislation in 1996. Also, the Korean government amended Commercial Act and made the Presidential Decree for using electronic bill of lading in 2008. In this paper the authors reveal the characteristics of the clause of UCC for electronic bill of lading. The characteristics of the clause are on the technical neutrality of the signature, the possibility of reissuance in alternative medium, and adoption of the concept of "control." It helps to suggest some implications for Korean government authority. The authors suggest the amendment of the Presidential Decree to the Korean government authority to use additionally digital signature authorized by non Korean government such as VeriSign. It will activate the use of electronic bill of lading issued by Korea repositary out of Korea.

The aim of this study is to examine of the cluster approach to ensure high rates of innovation, information and communication enterprises of information technology cluster in order to enhance the competitiveness of regions. Keeping with the previous literature, the present research determined that the novelty of the problem, concerning of the creation IT clusters as drivers of new generation, i.e. a kind of platform of "startup accelerators" through the creation of previously not existing in the country high-tech industries and sectors of the economy. The study employs system approach involves to determine prospective directions of the formation of clusters of IT industry, also applies structured approach to shows relationships between elements of cluster systems (participants of cluster), as well as focusing on some aspects of cluster development such as networking. Based on this analysis we have proposed to create clusters in regions, which can play the role of translator's innovations at the periphery of the country. This research shows that formation of IT clusters is one of the most successful tools to avoid of dependence of Kazakhstan from raw materials.

There have been numerous attempts at finding factors associated with profitability among hospitals in the Republic of Korea. Factors that have been shown to be related to hospital profitability have not yet been systematically reviewed. The purpose of this study was to compile and summarize published works investigating the factors associated with hospital profitability in the Republic of Korea. We searched Research Information Sharing Service, Korea studies Information Service System, Database Periodical Information Academic, Korean Medical Database, KoreaMed, and Google Scholar from 1980 to November 2013. In addition, we manually searched reference lists from eligible studies. Review of 20 peer-reviewed articles revealed that very few of the variables employed in the eligible studies exerted consistent association with profitability, with the exception of personal cost (i.e., employee salaries). Future studies should take our findings into consideration before conducting research on hospital profitability.

Recent trends in deep reinforcement learning (DRL) have revealed the considerable improvements to DRL algorithms in terms of performance, learning stability, and computational efficiency. DRL also enables the scenarios that it covers (e.g., partial observability; cooperation, competition, coexistence, and communications among multiple agents; multi-task; decentralized intelligence) to be vastly expanded. These features have cultivated multi-agent reinforcement learning research. DRL is also expanding its applications from robotics to natural language processing and computer vision into a wide array of fields such as finance, healthcare, chemistry, and even art. In this report, we briefly summarize various DRL techniques and research directions.

Since the global positioning system (GPS) has been included in mobile devices (e.g., for car navigation, in smartphones, and in smart watches), the impact of personal GPS log data on daily life has been unprecedented. For example, such log data have been used to solve public problems, such as mass transit traffic patterns, finding optimum travelers' routes, and determining prospective business zones. However, a real-time analysis technique for GPS log data has been unattainable due to theoretical limitations. We introduced a machine learning model in order to resolve the limitation. In this paper presents a new, three-stage real-time prediction model for a person's daily route activity. In the first stage, a machine learning-based clustering algorithm is adopted for place detection. The training data set was a personal GPS tracking history. In the second stage, prediction of a new person's transient mode is studied. In the third stage, to represent the person's activity on those daily routes, inference rules are applied.

Recent advances in artificial intelligence have allowed for easier sentiment analysis (e.g. positive or negative forecast) of documents such as a finance reports. In this paper, we investigate a method to apply text mining techniques to extract in the financial report using deep learning, and propose an accounting model for the effects of sentiment values in financial information. For sentiment analysis with keyword detection in the financial report, we suggest the input layer with extracted keywords, hidden layers by learned weights, and the output layer in terms of sentiment scores. Our approaches can help more effective strategy for potential investors as a professional guideline using sentiment values.

This paper deals with challenges of Mongolian government regarding Economic Development Plan (hereafter EDP). EDP has a long history, appearing first in the socialist countries, then in European countries following the European Reconstruction Plan after the Second World War, and then in many developing countries after they gained independence from the colonial rule. Major challenges of the Mongolian EDP are largely related to the absence or lack of integrated approach. We will propose a new integrated framework based on the approach suggested by UNDP. The new framework consists of 5 core areas; 1) institutions and governance, 2) evidence-based and empirically backed policy options, 3) development of budgeting and financial system, 4) and monitoring and evaluation (M&E), 5) capacity development. In order to identify challenges in Mongolia, the new integrated approach was applied to diagnose current states. To understand current states of EDP in Mongolia, survey regarding EDP in Mongolia was conducted for the 43 officials of Ministry of Finance. The same approach was applied for Five-Year Economic Development Plans in Korea to compare performances with EDP in Mongolia. On the basis of comparative analysis of EDPs in Mongolia and Korea, some lessons are suggested.
