In a most recent object tracking research work, applying Convolutional Neural Network and Recurrent Neural Network-based strategies become relevant for resolving the noticeable challenges in it, like, occlusion, motion, object, and camera viewpoint variations, changing several targets, lighting variations. In this paper, the LSTM Network-based Tracking association method has proposed where the technique capable of real-time multi-object tracking by creating one of the useful LSTM networks that associated with tracking, which supports the long term tracking along with solving challenges. The LSTM network is a different neural network defined in Keras as a sequence of layers, where the Sequential classes would be a container for these layers. This purposing network structure builds with the integration of tracking association on Keras neural-network library. The tracking process has been associated with the LSTM Network feature learning output and obtained outstanding real-time detection and tracking performance. In this work, the main focus was learning trackable objects locations, appearance, and motion details, then predicting the feature location of objects on boxes according to their initial position. The performance of the joint object tracking system has shown that the LSTM network is more powerful and capable of working on a real-time multi-object tracking process.

The purpose of this study is to analyze the various processes and patterns to build or synthesize class numbers in the 800 class of the Dewey Decimal Classification, Edition 20(1989). The results of the analysis are as follows: 1. The 800(Literature and rhetoric) class in the DDC system is the main class added analytico-synthetic principle positively to an enumerative scheme. 2. The facets to be a n.0, pplied in literature are language literary form literary period ; kind, scope, or medium ; notation 08(collection) or 09(criticism) literary feature, subject, author, etc. 3. In the 800 class, there are the five tables of precedence for literary forms aspects ; specific kinds of persons ; literary, period in relation to the aspects for works treating more than one literary form subforms, aspects and literary periods in the works treating a specific literary form. 4. The basic number synthesis of literary works proceeds through the various facets in the following sequence, as far as necessary for the item : base no. + literary form + literary time or period + kind, scope, or medium + notation 08 or 09 + subform + additional notation from T3C and other tables. 5. In view of the multiplicity of facets, their synthesis formulas take the following order : (1) Works about the literature : base no.(schedule) + language(T6) or form(T3B) (2) Works by or about individual author : base no.(schedule) + form (T3A) + period(schedule) + subform(T3A) (3) Works by or about more than one author, not restricted by language facet : base no.(schedule) + period(T1) ; base no.(schedule) + kind, scope, medium(T3B), or feature(T3C), or person(T5). (4) Works by or about more than one author, restricted by language facet : base no.(schedule) + form (T3B) + period(schedule) + subform(T3B) + notation 08 or 09(T3B) ; base no.(schedule) + notation 08 or 09(T3B) + 9(T3C) + area notation(T2) : base no.(schedule) + form (T3B) + notation 008 or 009(T3B) : base no.(schedule) + form (T3B) + kind, scope, medium(T3B) + notation 08 or 09(T3B) + period(schedule). (5) Affiliated literatures for which period numbers are not us base no.(schedule) + form (T3A or T3B), or notation 08 or 09(T3B) : base no.(schedule) + kind, scope, medium(T3B), feature(T3C), or person(T5) 6. The problems in the number building of the 800 class are the complexity and difficulty of number synthesis, the intrinsic weakness of from distinction and the inconvenience of retrieval inherent in the form class. In order to solve these problems, therefore, the citation orders and methods of DDC should be improved and synthesis patterns simplified from the point of view of its applicability and its usefulness in the "literature class".

Among the Chinese Characters originated in Japan, some of them are very ancient in their origin and others come to exist as different forms by being used widely in forged books in Chinese. These Characters can be divided into three groups. First, the Chinese Characters whose forms are different. Most of these are 'hoiui' (회의)character, being made by imitating the forms of the original Chinese Letters. These characters do have meaning but not pronunciation. This is one distinct feature of Chinese Characters originated in Japan. Second, the Chinese Characters whose meaning has been assigned by the Japanese people. These letters can be grouped into two. One is the letters whose meanings are entirely different from original Chinese Characters, and the other is the letters whose meanings are not known although their pronunciations are known. It can be explained that the letters with different forms are made because of the ignorance of letter's existence. Or, the letters were made on purpose in ordoer to be used in different meanings. Third, the Characters with a partial modification of original Chinese Characters. Among the Characters in three groups above, pure Japanese-made Chinese Characters are those in group one and three since those in group two are Chinese Letters whose meanings (or pronunciation) only are Japanese. As a results of detailed investigation of pure Japanese-made Chinese Character in JIS X 0208-1990, the followings are discovered: 1. Pure Japanese-made Chinese Characters are 147 in numbers. 2. The Characters which were originally Chinese but now considered to be Japanese-made are 5 in numbers. Among these letters, 39 Characters are not listed in TaeHanHwaSaJon(Whose fame is well known as the authoritative dictionary of Chinese Characters), 47 Characters are not found in the dictionaries of Chinese Characters compiled in Korea. 3. 14 Characters seem to be Japanese-made Chinese Characters although it cannot be said so with accuracy because of various meanings found in several dictionaries of Chinese Characrters.

이 연구는 코리안 디아스포라 문학이 가지는 이중언어 및 한국어 이외의 현지 언어로 발간된다는 특징에 주목하여 도서관의 자료분류에서 문학류의 언어에 의한 분류현황을 조사하였다. 이를 위하여 이 연구는 국내 대학 및 공공도서관이 소장하고 있는 디아스포라 문학 자료의 분류기호를 조사하였으며, 조사결과 국내 도서관들은 원작품의 언어에 분류하거나 또는 작가 중심으로 분류하고 있는 것으로 나타났다. 그러나 KDC의 문학류 분류규정에는 원작품의 언어에 대한 규정은 있지만, 작가에 대한 규정은 없는 것이 사실이다. 그러나 국내 도서관들은 동일한 작가의 작품을 언어에 따라 분산하는 것이 아니라 한 곳에서 이용할 수 있도록 하기 위하여 디아스포라 문학작품을 원작품의 언어가 아니라 작가에 따라 다르게 분류하고 있었다. 따라서 국내 도서관이 가지는 코리안 디아스포라 문학 작품의 분류의 혼란을 해결하기 위하여 이 연구에서는 KDC에 코리안 디아스포라 문학과 한국문학을 포괄하는 '한민족 문학'을 810에 분류할 수 있는 별법을 제안하였다. 그러나 이 별법은 코리안 디아스포라 문학에 대한 특별한 요구가 있는 도서관을 위한 시도적 제안이며, 이 별법의 적용을 위해서는 추가의 조사 및 연구가 반드시 필요할 것이다.

대부분의 영상을 이용한 물체추적은 적용환경을 단순화하거나 특정한 영상특징만을 적용할 수 있는 제한된 환경에서 잘 동작하기 때문에 이러한 물체추적방법은 지능자동차의 운전자보조시스템이 적용되는 복잡하고 동적인 교통 환경에서 원하는 물체를 추적하기는 어렵다. 이와 같은 물체간의 부분적인 교합이 존재하고 배경과 물체들이 동시에 동적으로 변하는 복잡한 환경에서는 물체의 색상, 외관, 외형 등과 같은 다양한 영상특징들을 적절하게 융합할 수 있는 구조가 요구된다. 본 논문에서는 기존의 파티클 필터를 이용한 적응형 융합구조[1]와 SIFT[2]를 이용한 영상특징 기술자를 강인한 영상특징으로 사용하고 시점 배경의 동적인 변화에 적응할 수 있도록 학습함으로써 추적의 강건성과 적응성을 향상시킨다. 제안된 알고리듬은 운전자 보조 시스템에서의 차량, 보행자, 자전거와 같은 도로상의 물체추적에 적용하였다.

Management systems for electronic library have been developed on the basis of Client/Server or ASP framework in domestic market for a long time. Therefore, both service provider and user suffer from their high cost and effort in management, maintenance, and repairing of software as well as hardware. Recently in addition, mobile devices like smartphone and tablet PC are frequently used as terminal devices to access computers through the Internet or other networks, sophisticatedly customized or personalized interface for n-screen service became more important issue these days. In this paper, we propose a new scheme of integrated management system for electronic library based on SaaS and Web Standard. We design and implement the proposed scheme applying Electronic Cabinet Guidelines for Web Standard and Universal Code System. Hosted application management style and software on demand style service models based on SaaS are basically applied to develop the management system. Moreover, a newly improved concept of duplication check algorithm in a hierarchical evaluation process is presented and a personalized interface based on web standard is applied to implement the system. Algorithms of duplication check for journal, volume/number, and paper are hierarchically presented with their logic flows. Total framework of our development obeys the standard feature of Electronic Cabinet Guidelines offered by Korea government so that we can accomplish standard of application software, quality improvement of total software, and reusability extension. Scope of our development includes core services of library automation system such as acquisition, list-up, loan-and-return, and their related services. We focus on interoperation compatibility between elementary sub-systems throughout complex network and structural features. Reanalyzing and standardizing each part of the system under the concept on the cloud of service, we construct an integrated development environment for generating, test, operation, and maintenance. Finally, performance analyses are performed about resource usability of server, memory amount used, and response time of server etc. As a result of measurements fulfilled over 5 times at different test points and using different data, the average response time is about 62.9 seconds for 100 clients, which takes about 0.629 seconds per client on the average. We can expect this result makes it possible to operate the system in real-time level proof. Resource usability and memory occupation are also good and moderate comparing to the conventional systems. As total verification tests, we present a simple proof to obey Electronic Cabinet Guidelines and a record of TTA authentication test for topics about SaaS maturity, performance, and application program features.

Altmetrics is an emergent research area whereby social media is applied as a source of metrics to evaluate scientific impact. Recently, the interest in altmetrics has been growing. Traditional scientific impact evaluation indictors are based on the number of publications, citation counts and peer reviews of a researcher. As research publications were increasingly placed online, usage metrics as well as webometrics appeared. This paper explores the potential benefits of altmetrics and the deep relationship between each metrics. Firstly, we found a weak-to-medium correlation among the 11 altmetrics and visualized such correlation. Secondly, we conducted principal component analysis and exploratory factor analysis on altmetrics of social media, divided the 11 altmetrics into four feature sets, confirming the dispersion and relative concentration of altmetrics groups and developed the altmetrics evaluation model. We can use this model to evaluate the scientific impact of articles on social media.
