The literature of national libraries

This article reports a study of the literature of national libraries, as evidenced by the content of three bibliographic databases – Library and Information Science Abstracts, Library and Information Science and Technology Abstracts and Web of Science – for 2014–2015. The results, which are neither comprehensive nor systematic, give an indication of the size of the literature, the sources, languages of publication, authorship pattern and content. The aim is to gain an overview of what is happening, currently, within publications from, and about, national libraries. The study suggests that the national library literature comprises about 100 items annually; the smallest body of literature for any of the main sectors of librarianship. This literature shows a Bradford scatter, with 94 journals and a few book and proceedings sources identified in this study. The main language of publication is English, although a variety of European languages are represented. National libraries worldwide are covered, with a focus on reports from Europe, North America and Australasia. Content is concentrated on general descriptions of libraries and their services, on collections and documents and on technology issues. Digital curation is a major part of 20% of the set. Issues of dataset curation per se have no almost presence in this set of national library literature.

Verbal Learning Style as the Least Preferred Learning Style of Students in an Asian Country

Learners develop a preferred way of choosing their learning styles because of their genetic makeup, their particular life experiences, and the demands of their present environment. Hence, the study aimed to determine the learning styles of freshmen students in the language class at Benguet State University, Philippines. Using descriptive - survey method, a questionnaire was used to gather data. It also used the Felder-Solomon Index of Learning Styles (FILS) which consisted of 44 questions designed to identify learning styles of learners. The study showed that their dominant learning style is Visual while Verbal is the least. According to their degree programs, the dominant learning style of the Bachelor in Secondary Education and Doctor of Veterinary Medicine students is Sensory while Bachelor of Science in Nursing, Bachelor of Science in Home Economics, Bachelor of Science in Information Technology, Bachelor of Science in Agricultural Engineering, and Bachelor of Science in Agriculture are all inclined to Visual. Based on the empirical findings and conclusions of the study, the researcher recommends that teachers should devise classroom activities suited for the students' learning styles focusing more on their verbal learning style that will activate their communication skills.

Smart Library Model for Future Generations

The concept of library in educational institutions is changing as the major constituents of library like physical books, hard copies of journals and newspapers are vanishing and a new format called e-format of these resources emerging through advents in computer science, information science and e-storage technology. The physical copies of books, journals and newspapers are thumbing and their electronic format do not need space for storage and single copy of such resource can be shared by any number of users so as the name of library has no longer validity. Hence libraries are now renamed as Resource Centres with online facility to provide resource sharing services to its registered users. Future libraries so called ‘Resource Centres’ do not need large reading rooms, large book/journal old volume storage area or even independent library building. Individual institutions also do not need independent libraries. There should be one Resource centre for a country or even only one for the entire world through which everybody can connect through ICT for uploading and downloading audio, text and video files so that equality in terms of accessibility to any of these types of resources can be maintained irrespective of gender, region, religion, economical background and the country origin of the users. The paper discusses the possibility of such transformation of Library into ‘Universal Resource Center’ and the consequences of such transformation to information sharing throughout the World and further changes in the model of costless higher education and extended opportunity for new knowledge creation. We also discuss how such transformed Libraries as Universal Resource Centres may provide automated customized service for individuals ubiquitously by incorporating smart library model.

Employment Status and Academic Competencies among the Information Technology Graduates: A Tracer Study

Information technology graduates of colleges and universities have increased rapidly while continuously facing stiff employment competition. The study traced the employability of the Bachelor of Science in Information Technology (BSIT) graduates of a university. It also described the profile of the BSIT graduates; assessed graduates' employment conditions; and determined the academic competencies utilized by the BSIT graduates in their current jobs. Using descriptive research design, the study employed standardized tool from Commission on Higher Education (CHED), and a sample of 87 BSIT graduates as respondents. The findings revealed that majority of the respondents were dominantly male, single, and from the Visayas region. Majority of them were regular or permanent in their current job and were locally employed and worked as an IT professionals in their present occupation. The graduates found their first job through advertisement. They utilized advanced information technology competencies in their jobs. Hence, their work matched to their tertiary degrees. The study provided information that the BSIT graduates of the University of Cebu - Banilad Campus are highly employable. After months of linkages for possible employers and career mapping of graduates, the school will be able to increase graduates assistance on job placements. After two hours of seminar on career mapping, the college will be able to assess the skills of the graduates to suggest possible areas of work to engage.

Out-of-the-box

Whilst my objective in Out-of-the-Box is to discuss the exciting new technologies set to transform our lives, we are never far from the real story which is about people. It is people who are variously flummoxed, fooled, facilitated or fascinated by the (technological) tools they use. Indeed the best definition of advanced technology is the technology that was introduced after you started work. There is a heady pace of technology advancement and a recurrent theme of the tensions as the technology clock and human clock move out of sync. In this article I take a look back at around half a professional life and, in a performance coach review, look at what we have achieved to help calibrate the challenges ahead. The centrepiece of this story is one of the editors of Business Information Review – Sandra Ward. Our joint history suggests the interleaved prospects for information science and information technology and the shape of things to come.

How to Design the E-Government Secure Cloud

Nowadays, cloud computing is the innovative product of the upgraded of information science technology. It is another great change following the transition from large scale computer to client-server in the last century. The concepts, such as cloud security, cloud storage, secure cloud, cloud hosting and cloud input, appeared after cloud computing. E-Government Information Security plays an important role in the development and establishment of E-Government. It is an important component part to use cloud security technology to establish our country’s E-Government secure cloud in current E-Government construction.

Spatial Risk Analysis of Water Borne Diseases (Bovine Leptospirosis) in the Rive Nile State-Sudan

Geographical Information Science (GIS) technologies have been used increasingly for ecology and epidemiology of water-borne diseases, providing approach for animal health issues. This study was set up to investigate the geographical distribution of Bovine that was affected by Leptospira hardijo, in River Nile state, on October 2012. Locations of targeted cattle were delimited using GPS. Fifty three (53) of blood samples were collected, and screened in the laboratory for Leptospira hardijo specific antibodies using indirect ELISA. 15.09% had evidence of infection as determined by the presence of anti-leptospira antibodies. It was inferred that no incidences were recorded in 45 locations out of the 53 selected locations in the state. Leptospirosis risk area for transmission was mapped using 5 km buffer distance. Animals’ movements routes were mapped with their contacts area and positive samples locations, hafair locations where animals contacts were mapped. This study demonstrated the value of GIS and GPS in disease mapping for animals’ health, and this might help veterinary authorities to implement strategic interventions for animal disease control.

Spatial modeling of ecological areas by fitting the limiting factors for As in the vicinity of mine, Serbia

Elevated arsenic (As) concentrations in soil are often found in the vicinity of certain mineral deposits that have been, or are currently, under exploitation, regardless of the target resource. Detailed study of such areas for safe agriculture requires considerable financial costs and long periods of time. Application of an appropriate spatial model that describes the behavior of arsenic in soil and plants can significantly ease the whole investigation process. This paper presents a model of ecological security of an area that, in the past, was an antimony mine and has a naturally high content of arsenic. For simulation and modeling the geographic information science (GIS) technology with the inserted predictors influencing the accessibility of As and its content in plants was used. The results obtained were the following: (1) a categorization of contaminated soils according to soil properties was developed; (2) the proposed methodology allows focusing on particular suspect area saving an energy and human resource input; and (3) new safe areas for growing crops in contaminated area were modeled. The application of the proposed model of As solubility to various crops grown around a former antimony mine near the village of Lisa, southwest Serbia showed that significant expansion of the areas suitable for growing potato, raspberry, and pasture was possible.

For the amplification process of sensor coarse signal, the use of adaptive genetic algorithm carries out mathematical modeling, the realization of the signal identification, acquisition and processing functions through software programming control. Finally, the intelligent processing of sensor coarse signal is successfully completed by the experiment system, and the signal processing effect is given as well.

People, organizational, and leadership factors impacting informatics support for clinical and translational research

BackgroundIn recent years, there have been numerous initiatives undertaken to describe critical information needs related to the collection, management, analysis, and dissemination of data in support of biomedical research (J Investig Med 54:327-333, 2006); (J Am Med Inform Assoc 16:316–327, 2009); (Physiol Genomics 39:131-140, 2009); (J Am Med Inform Assoc 18:354–357, 2011). A common theme spanning such reports has been the importance of understanding and optimizing people, organizational, and leadership factors in order to achieve the promise of efficient and timely research (J Am Med Inform Assoc 15:283–289, 2008). With the emergence of clinical and translational science (CTS) as a national priority in the United States, and the corresponding growth in the scale and scope of CTS research programs, the acuity of such information needs continues to increase (JAMA 289:1278–1287, 2003); (N Engl J Med 353:1621–1623, 2005); (Sci Transl Med 3:90, 2011). At the same time, systematic evaluations of optimal people, organizational, and leadership factors that influence the provision of data, information, and knowledge management technologies and methods are notably lacking.MethodsIn response to the preceding gap in knowledge, we have conducted both: 1) a structured survey of domain experts at Academic Health Centers (AHCs); and 2) a subsequent thematic analysis of public-domain documentation provided by those same organizations. The results of these approaches were then used to identify critical factors that may influence access to informatics expertise and resources relevant to the CTS domain.ResultsA total of 31 domain experts, spanning the Biomedical Informatics (BMI), Computer Science (CS), Information Science (IS), and Information Technology (IT) disciplines participated in a structured surveyprocess. At a high level, respondents identified notable differences in theaccess to BMI, CS, and IT expertise and services depending on the establishment of a formal BMI academic unit and the perceived relationship between BMI, CS, IS, and IT leaders. Subsequent thematic analysis of the aforementioned public domain documents demonstrated a discordance between perceived and reported integration across and between BMI, CS, IS, and IT programs and leaders with relevance to the CTS domain.ConclusionDifferences in people, organization, and leadership factors do influence the effectiveness of CTS programs, particularly with regard to the ability to access and leverage BMI, CS, IS, and IT expertise and resources. Based on this finding, we believe that the development of a better understanding of how optimal BMI, CS, IS, and IT organizational structures and leadership models are designed and implemented is critical to both the advancement of CTS and ultimately, to improvements in the quality, safety, and effectiveness of healthcare.

Result showed that, within the waters containing Potamogeton crispus population, the dissolved oxygen (DO) concentration increased from sunrise and droped continuously after sunset, following the water temperature variation. DO declined particularly apparently in the evening around 19:30, experienced a short-term recovery and then decreased until sunrise. The DO concentration within the open waters significantly correlated with water temperature variation; the DO variation tendency in the the boundary waters had the characters of that both for population-contained and open waters.The pH value within the population area increased after sunrise, and reached the highest at sunset, and then declined until sunrise on the following day, which was similar with that in the boundary waters; the pH values in the open waters area showed unobvious diurnal tendency. The DO concentration and pH value distribution followed this pattern: population area > boundary area > open waters. The total nitrogen (TN) content in the population and boundary area was highest around the sunrise and then decreased gradually, while the TN content at the open waters in the night was higher than in the day, and the highest TN content appeared at sunrise. The NH4+-N content variation showed no significant diurnal changes. The total phosphorus (TP) content with the population-contained area was more in the evening than in the day. The TP content reached the highest value at the sunrise, dropped rapidly, and then increased after sunset. The TP content in the open waters is higher in the evening than that in the day, with the lowest value appearing at the midday and highest value at dusk. Both TN and TP showed following distribution patterns: population area < boundary area < open waters. Potamogeton crispus had an important impact on DO, pH, and other water environmental factors, which in turn affected the migration of the endogenous nitrogen and phosphorus. Potamogeton crispus population had no significant effect on both pH value and the migration of nitrogen and phosphorus. Moreover, diurnal variation of DO had greater impact on the migration of endogenous nitrogen and phosphorus compared to photosynthesis. 参考文献 相似文献 引证文献

바이오에탄올 학술정보 분석

최근 세계 각국은 기후변화협약에 따라 온실가스 규제가 발효된 가운데 화석연료에 의한 이산화탄소 배출량을 최소화하는데 국력을 모으고 있으며, 이를 위한 조치와 국가 에너지 안보차원에서 신 재생에너지 개발에 박차를 가하고 있다. 현재 바이오연료는 전 세계적으로 전체 수송연료의 1% 정도를 차지하고 있으나 2030년에는 최대 5%까지 늘어날 것으로 예상된다. 이 글은 바이오에탄올 관련 학술정보를 개량 분석함으로서 기술 및 산업현황, 국내외 개발현황, 시장경쟁력 확보와 산업화에서 해결해야할 과제들을 분석하는데 도움이 되고, 우리나라의 관련 정책 및 기업의 장기 대응 전략 수립에 참고할 수 있을 것이다. 에탄올 혹은 에틸알코올은 흔히 알코올이라 불리는 술의 주성분으로 예로부터 우리들에게 자주 이용되어 왔다. 에탄올은 화학적 합성도 가능하지만 생물공정으로도 생산되는데, 이러한 생물공정에 의해 생산되는 에탄올을 바이오에탄올(bioethanol)이라 한다. 옥수수와 같은 전분을 원료로 하는 경우에는 산이나 아밀라아제로 불리는 효소로 먼저 전분을 포도당으로 전환하여 발효시킨다. "Web of Science"를 이용한 바이오에탄올 관련 학술정보 분석은 2001년 이후 12년간 검색어 '<TEX>$bioethandl^*$</TEX>'에 대한 검색결과 총 2,454건의 결과를 얻을 수 있었으며, 이를 다시 한국과학기술정보연구원이 자체 개발한 "수요자 맞춤형 연구개발 조기경보체제 구축"이란 정보분석 프로그램으로 바이오에탄올 관련 문헌의 연도별, 국가별, 연구기관별, 연구자별 현황 등을 분석하였다. 바이오에탄올 연구는 미국이 주도하고 있으며, 중국과 일본이 추격하는 양상을 보이고 있다. 한편 우리나라는 92편의 논문을 발표하여 브라질, 스페인, 캐나다, 인도에 이어 8위를 차지하였다. Recently, an understanding of new sources of liquid hydrocarbons such as bioethanol is economically very important. Bioethanol is actually ethyl alcohol or also referred to as ethanol, identical to drinking alcohol by its composition. There are mainly two ways of producing ethanol, namely by synthesis of hydrocarbons and from biomass. Only the second approach deserves the terminology 'bioethanol'. The present dissertation is also designed with purpose of developing the energy-saving process for the separation of bioethanol. The world population is expected to grow past 8 billion by 2030 which are almost 60% in Asia Pacific. History has shown that energy use rises much faster than population expands. World wide demand for energy will increase significantly during the next 15 years driven by population growth and the transition of emerging markets into the global economy. In developing nations, a smaller increment in GDP per capita yields a higher increment in energy consumption compared to developed countries. In this study, we analised total 2,454 dissertations for the bioethanol during the 2001~2012 periods by the programs of 'web of science' and 'recently developped program by Korea Institute of Science Technology Information'.

Acupuncture for Shoulder Pain After Stroke: A Systematic Review

Shoulder pain, for which acupuncture has been used, is a common complication after a stroke that interferes with the function of the upper extremities. The aim of this systematic review is to summarize and evaluate the effects of acupuncture for shoulder pain after stroke. Randomized controlled trials (RCTs) involving the effects of acupuncture for shoulder pain, published between January 1990 and August 2009, were obtained from the National Libraries of Medicine, MEDLINE(®), CINAHL, AMED, Embase, Cochrane Controlled Trials Register 2009, Korean Medical Database (Korea Institute of Science Technology Information, DBPIA, KoreaMed, and Research Information Service System), and the Chinese Database (China Academic Journal). Among the 453 studies that were obtained (300 written in English, 137 in Chinese, and 16 in Korean), 7 studies met the inclusion criteria for this review. All of them were RCTs published in China and reported positive effects of the treatment. The quality of the studies was assessed by the Modified Jadad Scores (MJS) and the Cochrane Back Review Group Criteria List for Methodologic Quality Assessment of RCTs (CBRG); the studies scored between 2 and 3 points on MJS, and between 4 and 7 points on CBRG. It is concluded from this systematic review that acupuncture combined with exercise is effective for shoulder pain after stroke. It is recommended that future trials be carefully conducted on this topic.

Methodology for assessing the usability of earth observation-based data for disaster management

The year 2010 through 2011 witnessed a number of disasters such as floods in Pakistan and Eastern Europe and earthquakes in Chile, China and Haiti. In response, earth observation (EO) data, geographic information science (GIS) technologies and services were used to provide information before, during and after the disaster occurred. However, use of EO for disaster management still faces a number of challenges due to the lack of common established standards for producing disaster products, the lack of coordination between a large number of suppliers leading to a large collection of datasets on websites of coordinating agencies and the lack of an established framework for monitoring and authenticating the level of quality and reliability of the products delivered to the targeted users. Assessing the quality of such products is a challenge to any potential user of such datasets. The methodology presented here integrates the role of EO expert and targeted end-user into one model where the first phase involves the expert and the second phase the end-user. The expert handles the technical and expertise aspect of EO data by rating the level of conformance of a product to the parameters of a “quality information template” (QIT), and the end-user explores various rated datasets and sets preferences for decision-making based on this QIT. The end-user has the possibility of accessing the product through an interactive web platform. The preferences set are used for weighing and ranking for the combination of the potential datasets and the task to be performed.

A Preliminary Study on the Multiple Mapping Structure of Classification Systems for Heterogeneous Databases

While science and technology information service portals and heterogeneous databases produced in Korea and other countries are integrated, methods of connecting the unique classification systems applied to each database have been studied. Results of technologists' research, such as, journal articles, patent specifications, and research reports, are organically related to each other. In this case, if the most basic and meaningful classification systems are not connected, it is difficult to achieve interoperability of the information and thus not easy to implement meaningful science technology information services through information convergence. This study aims to address the aforementioned issue by analyzing mapping systems between classification systems in order to design a structure to connect a variety of classification systems used in the academic information database of the Korea Institute of Science and Technology Information, which provides science and technology information portal service. This study also aims to design a mapping system for the classification systems to be applied to actual science and technology information services and information management systems.

Employment Attributes and Expertise of Bachelor of Science in Information Technology Graduating Students of AMA Computer College-Davao

This descriptive research was undertaken to determine the employment attributes and expertise of the graduating students of Bachelor of Science in Information Technology (BSIT) of AMA Computer College (AMACC) Davao. To realize these objectives, a researcher-made instrument using the 4-point Likert type questionnaire-checklist was used. The respondents of the study were the BSIT graduating students for School Year 2011-2012 who completed the required 486 hours on-the-job training. Statistical treatments used were percentage, Chi-Square, Pearson Moment Product Correlation and Multiple Regression. Results showed that the graduating students possessed the basic characteristics, such as personal qualities, core skills and subject knowledge required by business organizations for initial employment. The respondents showed high levels of expertise in terms of knowledge and skills. Findings showed that respondents from outside of Region XI have higher personal qualities than those from Region XI. Students from public schools have higher personal qualities and core skills compared to those from private schools (sectarian or nonsectarian). However, no significant relationship was revealed between profile and level of expertise in knowledge and skills of the respondents.

The Ambient Population and Crime Analysis

This article uses an alternative measure of the population at risk, the ambient population (provided by Oak Ridge National Laboratory), in crime rate calculations. It is shown through a variety of statistical analyses at two different scales of aggregation that this alternatively calculated crime rate is not always related to the conventionally calculated crime rate. The implications of this finding are that past theoretical testing and policy formation might have been based on spurious results, showing the importance of remaining current with the developments of geographic information science technologies and data availability when undertaking a spatial analysis of crime.
