Personal mobility, which was used exclusively for leisure activities, has recently been used as a means of transportation, and it is expected to increase its role as the next generation transportation. Sales of personal mobility are increasing rapidly, but the problem is that traffic accidents are also increasing. In this study, human body injury caused by various collisions between electric wheel users and road users that occur on bicycle or pedestrian roads mainly used by personal mobility is analyzed through collision analysis and collision risk analysis. In the case of the collision accident for electric wheel, it is analyzed that the road users are more likely to be injured on the pedestrian road than the bicycle road. In addition, the head hit each other or fall and hit the floor caused severe head injury.

The purpose of this paper is to investigate a possibility of applying multimethodological approach for solving a dilemma. The motivation of this attempt is that the two different approaches, the system dynamics and the theory of constraints, resemble each other in having mental models for describing the target system and using graphic tools for representing those mental models. After a brief discussion on the comparison of the two approaches, a combined method applying to the problem of dilemma is suggested. For an experimental example, the proposed approach is applied to the sales and finance conflict on an inventory issue. The study shows that the suggested approach is able to complement each other's drawbacks. Especially constructing a stock-and-flow model and implementing a computer simulation would be very useful for quantifying the system's behavior which is hardly tracked down when applying the theory of constraints alone.

One of the characteristics of contemporary interior design is the prominence of material and its challenge to the established concept of interior design. As material has risen to the new element of design, losing its old concept as something secondary surrounding space, it had become an useful instrument to create unique images as well as to express the paradigm of space that modern society demands. The active role of material has made itself one of the primary elements that make a difference in design. Particularly in commercial spaces where sales are important and attractive spaces are needed, material has been emergent conveying its appling to consumers. Therefore, this study analyses the materiality that material has and its characteristics represented as images in commercial spaces. With the analysis, it researches further into the unlimited possibility of material and show the way for modern interior design to head for.

The outpaced growth of online channel sales over the traditional retail sales is a result from superior shopping convenience that online stores offer to their customers. One major source of online shopping convenience is a personalized store that reduces customer's shopping time. personalization of an online store is accomplished by using various in-store shopping behavior data that the Internet and Web Technology provides. Brick-and-mortar retailers have not been able to make this type of data available for their stores until now. However, RFID technology has now opened a new possibility to personalization of traditional retail stores. In this paper, we propose BRIMPS (BRIck-and-Mortar Personalization System) as a system that brick-and-mortar retailers may use to personalize their business and become more competitive against online retailers.

In this Article the writer introduces the origin and preparation of "the UNIDROIT Principles of International Commercial Contracts". In May 1994 the Governing Council of the UNIDROIT gave its formal imprimatur to the UNIDROIT Principles and recommended their widest possible distribution in practice. After brief discussion of the establishment procedure of the UNIDROIT Principles the writer discusses the legal nature of the Principles as an international restatement of contract law. The UNIDROIT Principles has more flexibility than international convention. But it has deficit in the sense of legal stability. Also the scope of application of the Principles was discussed. It can be applied only to the international commercial contracts. It includes two basic principles in it's application, i. e. "commercial contracts" and "international contracts". For the rest of the Article the writer concentrates on the contents of the Principles and the basic ideas underlying the Principles from the point of view of the comparision between the UNIDROIT Principles and "the UN Convention on the International Sale of Goods" (CISG). The UNIDROIT Principles are only restatements and the CISG is an international convention. The application of the CISG is obligatory due to its nature as an international convention. In the contrary the possibility of the application of the UNIDROIT Principles is more flexible. The UNIDROIT Principles is a more comprehensive instrument than CISG. Therefore it can be applied to all kinds of international commercial contracts. In the contrary the CISG can be applied only to international sales contract. Since CISG only deals with contracts for the sale of goods, and the scope of the UNIDROIT Principles is much wider, no overlap can occur where contracts other than sales contracts are concerned. Rather the UNIDROIT Principles can supplement the CISG and the CISG also can be criteria in interpreting the UNIDROIT Principles. As the conclusion the writer summarizes the meanings of the UNIDROIT Principles and presupposed the futur perspectives of the Principles.

In the fisheries industry, the cost of oil Is the greatest factor, contributing 25% 40% of the cost of production. In order to support fisheries, the government has supplied large amounts of money for oil to the fisheries industry. However, the elimination and restriction against the subsidy of fisheries has been actively discussed throughout international organizations Including the WTO. The purpose of this thesis is to study the existing issue of subsidies on the fisheries Industry, which is currently disputed in international organizations, and predict a future policy about the oil supply that considers the most important factors on fisheries. In chapter 2, the paper begins by outlining the tendencies of discussion in relation to the subsidy on fisheries among international organizations, and categorizes them on the basis of their types. Chapter 3 defines the current conditions and characteristics of the Korean subsidy on fisheries and analyzes which portions of the subsidy on fisheries should be eliminated first when it is prohibited. In chapter 4, procedures and problems for producing tax-free oil are discussed, because tax-free oil has a higher possibility of being ruled out. Chapter 5 proposes a reasonable plan concerning oil supply policies for maintenance or enrichment of the fishing industries, post the elimination of subsidies. Conclusions were drawn in eight areas as a result of this study: 1) securing the large storage of oil, 2) extending customers of oil to include non-fishermen, 3) coordinating the segmentation of marketing area, 4) diversification of the sales goods, 5) producing oil sales experts, 6) developing original brands, 7) expanding the purchasing area to buy oil in the international market, and 8) operating funds to stabilize oil price. It would not be appropriate to wait until international organizations decide to ban the subsidy of fisheries. Corresponding plans ( such as securing the large storage of oil) tend to be large scale and long-term projects because they take a number of years, from designing the oil storage tank to selecting the proper region and initiating the construction. Therefore, it is strongly suggested that any extensive and time consuming projects including preparation for the tax-free oil should be completed in new actions before the ban by the international organizations.

The purpose of this study was to apply the deep running method to real estate price index predicting and to compare it with the time series analysis method to test the possibility of its application to real estate market forecasting. Various real estate price indices were predicted using the DNN (deep neural networks) and LSTM (long short term memory networks) models, both of which draw on the deep learning method, and the ARIMA (autoregressive integrated moving average) model, which is based on the time seies analysis method. The results of the study showed the following. First, the predictive power of the deep learning method is superior to that of the time series analysis method. Second, among the deep learning models, the predictability of the DNN model is slightly superior to that of the LSTM model. Third, the deep learning method and the ARIMA model are the least reliable tools for predicting the housing sales prices index among the real estate price indices. Drawing on the deep learning method, it is hoped that this study will help enhance the accuracy in predicting the real estate market dynamics.

A blockchain is a technology in which all nodes participating in a distributed network manage each transaction's contents without a central server managing the transaction, which is a record of the transaction. The block containing the transaction record of a specific period is connected to the blockchain by referring to the hash value for the previous block, and the chain with the new block added is shared with all nodes again. Transactions using existing certificates will pass through FinTech, and in the near future, applications using blockchains are expected to emerge. In this study, we analyze the problems of the existing model, and propose a transaction model that applies the blockchain to come. Among various applications, this study develops a trading model targeting the energy sales market among the topics that will lead the fourth industrial revolution. As a result of analyzing the proposed model, it was possible to be sure of the possibility of a safer energy sales transaction than the existing method.
