Purpose: Globally, falls are a major public health problem. The study aimed to evaluate the predictive validity of the Timed Up and Go test (TUGT) as a screening tool for fall risk. Methods: An electronic search was performed Medline, EMBASE, CINAHL, Cochran Library, KoreaMed and the National Digital Science Library and other databases, using the following keywords: 'fall', 'fall risk assessment', 'fall screening', 'mobility scale', and 'risk assessment tool'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Thirteen studies were analyzed using meta-analysis with MetaDisc 1.4. Results: The selected 13 studies reporting predictive validity of TUGT of fall risks were meta-analyzed with a sample size of 1004 with high methodological quality. Overall predictive validity of TGUT was as follows. The pooled sensitivity 0.72 (95% confidence interval [CI]: 0.67-0.77), pooled specificity 0.58 (95% CI: 0.54-0.63) and sROC AUC was 0.75 respectively. Heterogeneity among studies was a moderate level in sensitivity. Conclusion: The TGUT's predictive validity for fall risk is at a moderate level. Although there is a limit to interpret the results for heterogeneity between the literature, TGUT is an appropriate tool to apply to all patients at a potential risk of accidental fall in a hospital or long-term care facility.

In recent, library is considered as an integrated knowledge convergence center that can respond to various requests about information service of users. Therefor it is necessary to establish a novel information system based on information communications technologies of the era. In other words, it is currently required to develop mobile information service available in portable devices such as smart phones or tablet PCs, and to establish information system reflecting cloud computing, SaaS, Annotation, and Library 2.0 etc. In this paper we design and implement a library information system using collective intelligence and cloud computing. This information system can be adapted for the varieties of mobile service paradigm and abruptly increasing amount of electronic materials. Advantages of this concept model are resource sharing, multi-tenant supporting, configuration, and meta-data supporting etc. In addition it can offer software on-demand type user services. In order to test the performance of our system, we perform an effectiveness analysis and TTA authentication test. The average response time corresponding to variance of data reveals 0.692 seconds which is very good performance in timing effectiveness point of view. And we detect maturity level-3 or 4 authentication in TTA tests such as SaaS maturity, performance, and application programs.

This study analyzes the problems in reading program of public libraries and provides some suggestions for the program development and management. For this analysis, I sampled and examined 350 news articles to reading programs done in the public libraries between 2013 and 2015. The result shows that 41.4% of the collected articles were the news about the reading programs in Seoul Metropolitan areas. While the articles about simple reading programs occupied 69.9%, the mixed activity programs reached a significant amount in total. In addition, 51.3% of program participants was under the elementary children and their parents, but only 9.0% program participants came from low socioeconomic status classes. 86 reading programs (28.4%) were designed for one-day events without a long-term policy. Based on such analyses, this study provides three suggestions: utilizing public relation teams and communicating mass media to advertize reading programs to local residents, developing systematic reading programs in users' needs, managing the reading programs for all kinds of local residents.

Originally the concept of the traditional resource sharing has been discussed in the context of bibliographic materials, and has been labor-intensive and high-cost activities. The technology has had a great impact on such pattern of the resource sharing, and has expanded the limited scope of the traditional concept into the sharing of library information in the levels of local, regional and national systems, and expertise, materials, facilities, equipments and personnels of the library system. While the traditional circulation service as a basic method to share library materials by users can provide the resource to a single person at a time, the electronic resource can be shared, by multi-users at a time anytime anywhere. The maximization of the electronic resource sharing requires that publishing process should be fundamentally changed and articles, books, chapters, speech manuscripts, music scores, maps, sound, and other formats of materials should be prepared in machine readable format. This study examined the positive effects of the technology on the resource sharing, but not investigate the concrete and complex problems as to the cost, guidelines, detailed procedures, design details, and intellectual properties and protection involved in the resource sharing. Some findings extracted from the study can be summarized as follows; (1) ILL will lose its meaning as a method to share the materials if they are all in the electronic format and the phrase 'networked information resource' becomes omnipresent. (2) The technology keeps on changing the concept of resource sharing. Today, the scope of resource sharing not only encompasses the sharing of the primary and secondary materials but also the sharing of the processings(eg. cataloging), expertise, user education, special facilities, and the integrated automated library systems. (3) The sharing of the networked resource will be a method to provide better services for library users in the low cost. (4) The a n.0, pplication of the technology to the resource sharing should be focus on the method which allows an end-users to do the direct access to the needed materials, and to be delivered the primary document as soon as possible.

This paper suggests a 8-bit RISC microcontroller, which has a 4-stage pipeline architecture. Many low-power design techniques that have been proposed by previous works are adopted into it. The proposed microcontroller consumes only 600㎼ per MIPS for 0.6 ${\mu}{\textrm}{m}$ CMOS process and even lower power of 70㎼ per MIPS for 0.25${\mu}{\textrm}{m}$ process. The RTL level design of this microcontroller is carried out using VHDL. The functional verification is thoroughly done at the gate level using 0.6${\mu}{\textrm}{m}$/0.25${\mu}{\textrm}{m}$ CMOS IDEC standard cell library. This microcontroller contains 7000 NAND gates on a 0.36$\textrm{mm}^2$ die using 0.25${\mu}{\textrm}{m}$ process. Finally the comparison of power consumption with other conventional microcontrollers is provided.

Prisons are mostly filled with social deviants and like other correctional institutions, deserve organized information (provision) centers such as library. A study on library resource needs and accessibility by prison inmates was conducted at Kuje prison, Abuja and Kaduna prison, Kaduna, Nigeria, both of which have functional libraries. A sample of 898 inmates was randomly selected from all the convicted inmates in the two prisons. A total of 106 inmates were selected from Kuje prison and 792 from Kaduna prison. A well-structured questionnaire was used to collect data from the inmates. All the 898 inmates responded. A total of 786 (87.9%) males and 112 (12.4%) females were involved in the study. With regards to the educational level attained by the inmates, 347 (38.6%) had Junior Secondary School Certificate while 323 (30.0%) had Senior School Certificate both accounting for 74.6% of the sampled population. In areas of information needs, 94.5%, 96.1%, 98.7%, 99.4%, 100%, and 100% of the respondents indicated that information on current affairs, survival and coping, educational support, legal aid, skill acquisition, and health, respectively were highly needed by the inmates. Out of the 12 information resources listed, only newspaper, novel, handbook and manual, and bulletin were readily accessible with percentage accessibility of 60.7, 7.8, 6.8, and 1.9, respectively. One major reason adduced by the respondents for limited access to information resources was the very strict rules and regulations in the prison. Providing more library resources and granting the inmates more access to the library would assist in character reformation and rehabilitation of the inmates.

[Sinpyon-jejong-kyojang-chonglok] is a bibliography and subject catalog, called [Sokjangkyoung-catalog], which was introduced in Coryo dynasty. It was developed by [Degakguksa Yuichun] in 11th century(1090) and holds an important feature in Korean cataloging history as well as in the world cataloging history as the first [Sokjangkyoung-catalog]. This study investigates the entry description of [Kyojang-chonglok] and analyzes it in the contemporary perspective of Cataloging Rules. The study has found that the [Kyojang-chonglok] Follows the 'title main entry method'. Since the modern a n.0, pproach a n.0, pplies direct method which utilizes title, rather than indirect method which utilizes author name, we could safely assume that [Kyojang-chonglok] follows the modern principles such as standardization of cataloging and unification of bibliographical description. We could also extend our findings to conclude that [Sinpyon-jejong-kyojang-chonglok] created a foundation for modern 'title main entry system' such as ISBD and KCR3. Also, the bibliographical description of [Kyojang-chonglok] meets the conditions of B. S. Wyner, shown in the below. 1) logicality 2) flexibility 3) quickness 4) compactness 5) economic
