This study considers various equipment used for collecting traffic information, analyzes that equipment in accordance with the operation states and problems, the suggests a process of traffic information collection using drones to reduce the problems and errors of existing methods. In this field investigation study using drones, the results were analyzed by altitude, angle, and direction. We suggested a standard for drone filming-based traffic information collection. Pros and cons were presented through comparison and review of the existing traffic information collection method and traffic information collection method using drones. Drones can be used to collect various traffic information from the air, more extensively than is possible with existing traffic information collection points, and provide traffic information to users proactively, responding to various accidents and disasters. It is believed that it will be possible to contribute to achieving accurate traffic volume investigation by supplementing the traffic information collected by fixed equipment, including changes and enlargement of collecting points as needed.

This paper proposes Electronic Credit Card(EMV) processing procedures for a credit payment method which can be applied to Korean ETCS(Electrical Toll Collection System). In Korea, Korea Highway Corporation services contactless ETCS's called by Hi-Pass and Touch-Pass system at present. These systems operate on a pre-paid payment method similar to electronic money. On the other side, a credit payment method based on credit card has an advantage which does not require pre-paid. The introduction of credit payment method to ETCS is in preparation. In this paper, we propose EMV processing methods based on a credit payment method which can be applied on ETCS.

Libraries which have a large amount of genealogical materials need to manage them in a special way differing from the other materials. Although genealogy related materials have high pragmatic value, the reality is that the acquiring methods are limited to collect the genealogical table or is not systematic. Even the genealogical materials held in the library are not rationally organized. Under such circumstances, this study investigates the cases of the management of genealogical materials both in domestic and foreign institutions, and also examines the real situations of material organization such as the collection, the classification and the cataloging on the centering of the libraries which hold a large amount of genealogical materials. On the basis of this investigation, the study aims to measure the enhancement of the methods for collecting and organizing genealogical materials which enable the collection management and information retrieval fur them to be efficient and effective.

The operational aerosol retrieval algorithm for the Moderate Resolution Imaging Spectroradiometer (MODIS) measurements was recently updated and named collection 6 (C6). The C6 MODIS aerosol algorithm, a substantially improved version of the collection 5 (C5) algorithm, uses an enhanced aerosol optical thickness(AOT) retrieval process consisting of new surface reflection and aerosol models. This study reports on the estimation and validation of the two latest versions, the C5 and C6 MODIS aerosol products over the East Asian region covering $20^{\circ}N$ to $56^{\circ}N$ and $80^{\circ}E$ to $150^{\circ}E$. This study also presents a comparative validation of the two versions(C5 and C6) of algorithms with different methods(Dark Target(DT) and Deep Blue (DB) retrieval methods) from the Terra and Aqua platforms to make use of the Aerosol Robotic Network (AERONET) sites for the years 2000-2016. Over the study region, the spatially averaged annual mean AOT retrieved from C6 AOT is about 0.035 (5%) less than the C5 counterparts. The linear correlations between MODIS and AERONET AOT are R = 0.89 (slope = 0.86) for C5 and R = 0.95 (slope = 1.00) for C6. Moreover, the magnitude of the mean error in C6 AOT-the difference between MODIS AOT and AERONET AOT-is 40% less than that in C5 AOT.

The purpose of this study has its meaning to indicate the direction on collection and preservation of national literature which is one of the must important functions of the Central National Library. The Central National Library is, however, a representative library of our country and collect every kind of literature and to meet the requests of its users, the present situation of The Central National Library can't be performed sufficiently on these actions. According to studies of this paper, it have suggested the following five methods as a method of collecting national literature. First, the method by registering copyright endowing the number of copyright like ISBN. Second, the method a n.0, pplied by revising and su n.0, pplementing present legal deposit system. Thirdly, the method that the central one institution secure national budget collect literature of nation i.e., central intensive collection one. Fouthly , method of collecting literature by partial charge through local library networks. Fifthly, method by subject intensive collecting. As the preserving method of national literature, this research has indicated the following two ways. First, to keep the literatures forever, the method of The Central National Library keeps records as a limited volume. Second, The method of dispersing records as the local libraries. To put these methods into practice, it must be preceded that not only national helps, budget secures are needed but special committee must be organized to keep and preserve national literatures and material range also be extended and bibliographies for information data issuing must be worked out.

In November 1983, Deng Sanmu's wife, Zhang Jianquan, donated a large number of Deng Sanmu's original seal carving stones and seal cutting scores to the Heilongjiang Provincial Museum in China. Therefore, the Heilongjiang Provincial Museum of China is the richest and most authoritative place to collect Deng Sanmu's original seal cutting stones and seal carving scores. According to the fieldwork, the original seal cutting stones and the seal cutting score donated by Deng Sanmu's wife, Zhang Jianquan, include Deng Sanmu's seal cutting inscriptions made between 1922 and 1963. In addition, Deng Sanmu's own life and career in the art are documented in detail in his markings, so the seal cutting inscriptions of Deng Sanmu in the collection of the Heilongjiang Provincial Museum of China are quite representative. We paper is a documentary review and study of the seal inscriptions of Deng Sanmu in the collection of the Heilongjiang Provincial Museum in China. For the accuracy and richness of this study, a total of 89 representative seals in the collection are used as primary sources to study Deng Sanmu's seal cutting emulation method. The specific content is centered on ancient seals, Qin seals, and Han seals, from which the lineage of Deng Sanmu's emulation methods of seal cutting is further clarified.

Social infrastructure is the basis of public welfare and should be recognized and managed as important assets. Bridge is one of the most important infrastructures to be managed systematically because the impact of the failure is critical. It is essential to monitor the performance of bridges in order to manage them as an asset. But current analytical methods such as predictive modeling and structural analysis are very complicated and difficult to use in practice. To apply these methods, structural and material condition data collection should be performed in each element of bridge. But it is difficult to collect these detailed data in large numbers and various kinds of bridges. Therefore, it is necessary to collect data of major measurement items and predict the life of bridges roughly with advanced information technologies. When certain measurement items reach predefined limits in the monitoring bridges, precise performance measurement will be done by detailed site measurement. This paper describes the selection of major measurement items that can represent the tendency of bridge life and introduces automated bridge data collection test-bed using wireless sensor network technology. The following will be major parts of this paper: 1) Examining the features of conventional bridge management system and data collection method 2) Mileage concept as a bridge life indicator and measuring method of the indicator 3) Test-bed of automated and real-time based bridge life indicator monitoring system using wireless sensor network
