Korea has been designated as a National Intangible Cultural Heritage with outstanding value among intangible cultural heritage. We have supported various exhibitions and performance activities, and the Intangible Cultural Heritage Public Events. However, in recent years, more diverse policies have been pursued in order to revitalize transmission activities and the State is leading the Completion examination system. In order to improve the utilization of crafts, we introduced a Craft Bank System. In addition, to increase the marketability of crafts, we have implemented the certification system for crafts. For the diversity of transmission activities, we are promoting the Transmission Education School System. In order to fuse traditional activities, the Intangible Cultural Heritage Exhibition is being held and the World Heritage Forum is being pursued. In this study, we analyze various policies of the new intangible cultural heritage and investigate the problems and seek ways to improve them.

Rapid development of internet service is enabling internet banking services in anywhere and anytime. However, service access through internet can be exposed to adversary easily. To prevent, current service providers execute authentication process with user's identification and password. However, majority of users use short and simple password and do not periodically change their password. As a result of this, user's password could be exposed to attacker's brute force attack. In this paper, we presented enhanced password system which guarantee higher security even though users do not change their current password. The method uses additional secret information to replace real password periodically without replacement of real password.

Recently, Chen et al.'s proposed mutual authentication scheme based on the quadratic resiidue, finding the squaring root problem, for avoiding exhaustive search on the server. But, if a malicious reader sends same random value, the tag is traced by an adversary. Moreover, there is realization problem because of its limited ability to compute squaring and hash function. In this paper, we analyze Chen et al.'s scheme and its weakness. Furthermore we present an improved mutual authentication scheme based on the quadratic residue which solves the tracing problem by generating random value on the tag and uses only squaring. We also make the scheme satisfy to forward secrecy without updating and synchronizing and avoid exhaustive search.

Database construction of basic elements for displaying CCTV informations(the location, direction, distance, maximum distance, Tele mode angle view, Wide mode angle view, etc.) is conducted by complete survey about CCTV information in model area. Automatic mapping algorithm is suggested to schematize and visualize it on the basic of the investigated CCTV informations. In the result, the CCTV locations in partial areas are duplicated on about 11 percents. Duplicated ones among twelve CCTVs are total five. If the redesign of CCTV location and direction by displaying the CCTV informations based on the suggested algorithm is performed, it can be used as scientific explanations.

In korea, Freight generation models developed in korea were estimated by spatial unit method which predict freight flow by traffic zone. But it is difficult to predict freight generation using these models, because there are the difference of the totality method of sampling data on freight volume and the variability of the variables by these models on each case study, This study developed new estimation model to predict freight flow which is generated from each company using the characteristics of each company such as the freight outbound & inbound volume, the number of employee, sales, gross area, land area. This model is simpler than the that of spatial unit and can apply to the other region. The subjects of study were companies in metropolitan area and types of model were exponential regression models. The adequate explanatory variable in the models were sales. this study have a uniqueness apply micro research method to estimate freight generation not use spatial unit method but use flow unit method by each company unit.

According to the article of inventory in the act of public records management from $29^{th}$ January on 1999, record repository, special repository and the archives have been doing inventory totally once every two years. As the archives have acquisited incredibly and explosively lots of archives, this has induced a lot of problem in inventory activity due to legacy inventory acts. To solve these problems, the author have revised and legislated on $29^{th}$ Oct. 2016. The purpose of this study is to point out the problems that prior uniformal inventory cycle and to explain in detail that the contents of the newly revised article, and a benefit and expectations of practical inventory activity. The major revision of article is inventory cycle of at least totally once every four years and the act of obligation on a after-process of inventory.

These days Taekkeon of Shin Han-Seong is newly rased as traditional martial which made up in the academic world. The reason why is that create new shaped Traditional Taekkeon which stipulate good points of systematize Martial Arts to register Song Duck-Ki Taekkyeon eleven figures's a piece of skills to cultural assets. This research show how Shin Han-Seong make up Taekkyeon to register to intangible cultural assets, and found next conclusion and meaning. First, skill organization of Song Duk-Ki Taekkeon that is only one modern Taekkeon's initiator have been transmitted for a piece of skills of playing figure which don't have regular system. But Taekkyeon which have regular system have been developed by Shin Han-Seong, finally Taekkyeon is approved to intangible cultural assets. Second, Shin Han-Seong modernized Taekkyeon by borrowing training system of Judo, Fencing, Hapgido, Taekwondo, Karate. But people criticize that Song Duk-Ki Taekkeon is not initiate with original thing. Third, Shin Han-Seong made the grade classification and practical technique screening, Bon-Dae Buigi Twelve part like Pomse of Taekwondo (there is no for traditional Taekkyeon). And he contributed to popularization and modernized learning system by pursuiting sportization. Through this research geared up Taekkyeon's original shape and generational outline about skill transition or composition. And it gave important data for understand about Taekkyeon controversy which scattered.

The university must open the "School Development Plan and Specialization Plan" at the university allimi. The reason for this is the Special Act on the Disclosure of Information by Educational Institutions, enacted on May 25, 2007, and the Plan for Reform of University Reform announced by the Ministry of Education on Mar 28, 2014. Therefore, we examined the similarity and standardized model of the "School Development Plan and Specialization Plan" published by a total of 137 colleges. As a result of the study, only 17(12.4%) of the college produced information in two ways(school development and specialization), and the rest were not. The school development plan presented quantitative indicators such as world number one, The characterization plan presented qualitative indicators such as human. Based on this, standardized research procedures and conception are presented.

The main focus of this paper is to analyze trend of event informations in a variety of mass media by graphical visualization in axis of the time and location. Especially, continuity analysis based on user-generated social media can reflect the social impact of a certain event according to change time and location and their directional changes. To reveal the characteristics of continuous events, we survey the data set collected from news articles and tweets during two years. Based on case studies on 'disease' and 'leisure', we verify the effectiveness and usefulness of our proposed method. Even though some events occurred during same period, we showed directional changes which have high-impact in social media referred user interest's, compared with fact-based continuous visualization results.

As the structure of an enterprise becomes complicated and distributed, the interoperability between workflow systems for the process automation among partners or departments is rising as an important issue. For the interoperability between workflow systems, we propose a data exchange scenario based on mobile agents. The scenario includes sequence diagrams and methods defined by UML. The mobile agents are designed based on the mobile agent standard, MASIF, developed by OMG. In order to prove the applicability of the mobile agent technology to workflow interoperability, we have developed a prototype function which creates and transfers mobile agents.
