  • The distribution of volume fraction, mean diameter and number density of soot particles are measured quantitatively in a co-flow ethylene diffusion flame using a simultaneous LII/LIS measurement technique. The LII/LIS system and the measured values are, respectively, calibrated and evaluated by comparing to the informations obtained from laser light. extinction/scattering experiments, LII signal shows some sensitivity to the laser light intensity when laser power density exceeds a certain value(threshold). It is also found that there is an optimal laser intensity and a delay time in order to obtain the best result using the simultaneous LII/LIS measurement technique.

  • 본 연구의 목적은 우리나라 문헌정보학계에 iSchool에 대한 학문적 관심을 환기시키고 이를 통해 iSchool에 대한 연구의 시발점을 마련하고자 하는 것이다. 연구목적 달성을 위해 문헌정보학자들과의 심층인터뷰를 진행하였으며 인터뷰자료는 질적 분석 방법을 활용하여 분석하였다. 분석결과 우리나라에 iSchool을 도입하기위해서는 교과과정의 개편을 통한 교육의 다변화가 필요하며 iSchool 도입을 통해서는 융, 복합 연구 및 교육의 기회, 현 문헌정보학의 위기 돌파를 위한 외연의 확장, 문헌정보학에 대한 새로운 이미지의 구축이 가능할 것이라는 기대가 있는 것으로 나타났다. 하지만 iSchool의 도입은 사서양성 교육기관으로서의 문헌정보학의 정체성마저 위협할 수 있다는 위기의식 또한 존재하는 것으로 나타났다.

  • LIS's of cis and trans-methyl-2-phenylcyclopropanecarboxylate, cis and trans-t-butyl-2-phenylcyclopropanecarboxylate, cis and trans-N,N-dimethylcyclopropanecarboxamide, trans-2-phenylcyclopropyl methyl ketone and trans-2-phenylcyclopropyl t-butyl ketone have been studied. The LIS's hold the McConnell-Robertson relation and are mainly influenced by the steric effect. LIS's of trans isomers are larger than those of cis isomers. In trans isomers, the LIS's decrease in the following order: methyl ketone > methyl ester > N,N-dimethyl amide > t-butyl ketone${\sim}$t-butyl ester.

  • Purpose: This study aims to assess the level of job satisfaction among the practicing Library and Information Science (LIS) professionals in India. Some of the key variables studied include salary, work environment, professional position, working hours, location, employee participation in administrative matters, recognition, and advancement. Scope: The study is limited to LIS professionals in India; however, the results of the study show some degree of commonality among LIS professionals across the world. Methodology/Approach: The study has been purely undertaken by analyzing the primary data collected from practicing library and information professionals across India by circulating an online questionnaire, using Google services and by posting the link on various social groups and other social networking sites such as Groups, Facebook, LinkedIn, discussion forums, and e-mails. Findings: Responses were generated across 20 states and union territories of the country, representing 88.15% territory of India. Of the total responses generated, 72.88% are males and 27.12% females. From the data analysis it emerged that every third library professional in India enters in to LIS profession by chance and not by choice, as 35.59% respondents expressed that they landed in the LIS profession by chance and 60.45% by choice. More than 77% respondents have expressed their willingness to change their present employer, if given better opportunity. More than 80% professionals either fully or partly agree that most of the LIS professionals across India are dissatisfied with their employers. All these and many more areas have been explored, which reflect the aspects of job satisfaction and dissatisfaction among LIS professionals in India.

  • 본 연구는 급변하는 대학환경에 대응하기 위한 전략으로 문헌정보학과에 대한 인지도 및 선호도를 조사할 뿐만 아니라 문헌정보학과의 진로에 대한 인식을 높이고자 수행되었다. 이를 위해 고등학교 학생들을 대상으로 설문조사를 수행하였으며, 그 결과는 다음과 같다. 첫째, 우리나라 고등학생들의 사서 및 문헌정보학과에 대한 인지도는 보통 이하로 매우 낮은 것으로 나타났다. 둘째, 문헌정보학과의 진로에 대한 인지도와 선호도를 조사하였으며, 문헌정보학과를 졸업한 후 진출할 수 있는 직장으로 생각되는 기관에 대해 공공도서관, 국가도서관, 대학도서관, 학교도서관 순으로 응답하였으나, 취업하고 싶은 직장은 방송국 자료실, 국가도서관, 학교도서관, 대학도서관, 공공도서관, 포털업체 순으로 나타났다. 셋째, 문헌정보학과의 진로에 대한 인지도는 문헌정보학과에 대한 선호도에 매우 큰 영향을 미치는 것으로 나타났으며, 문헌정보학과에 대해 들어본 적이 있는 학생들이 문헌정보학과를 선택할 확률이 높다고 예측할 수 있다. 본 연구결과는 문헌정보학과의 진로에 대한 인식을 높임으로써 문헌정보학의 경쟁력을 높이는데 활용될 수 있을 것이다.

  • The paper aims to present a comparative analysis of scholarly research output in the fields of Library and Information Science (LIS) in India and South Korea. The Web of Science database was used to retrieve the bibliographic data of the Indian and South Korean LIS published documents during 2001-2020 and the indicators were included in the analysis: research productivity, publication-quality, most prolific authors, institutions and journals, "Annual Growth Rate (AGR)", "Compound Annual Growth Rate (CAGR)", "Relative Growth Rate (RGR)", and "Doubling Time (DT)". All types of documents such as articles, conference papers, book reviews, corrections, editorial materials, so on were included in the study. MS Excel, VOS viewer, and bibliometrix (R-tool) software were used for tabulation and mapping. The results show that South Korea placed the top in the overall output of LIS research publications during the last two decades. The Indian LIS research output, Annual Growth Rate (AGR), and Compound Annual Growth Rate (CAGR) were good compared to South Korean LIS publications. In addition, the South Korean LIS researchers' output has increased rapidly in terms of publications, citations, average citations. Gangan Prathap (India), Seyoung Lee, and Heejin Lee (SK) are the most prolific authors; Indian Institute Technology, Delhi and Yonsei University, Seoul are the most prolific institutions; and the Scientometrics journal was the most preferred journal by the Indian and South Korean LIS researchers during the study period. The results of this study are useful to administrators, policymakers, and academics. In addition, the scope of this study might include looking at research published by LIS scholars in India and South Korea, as well as examining all types of academic publications.

  • Based on the design of the LIS of GuangZhou and BeiJing, this paper discusses the resolution of the LIS with the kernel of process management. It applies the idea of workflow in the management supporting stratum, applies the process-oriented mechanism in the definition, coordination, supervision and control of the management process. The scheme has the character of information-media-oriented, work process dynamic changing supported, application system extended and restructure supported and is independent of the running environment of specific work.. Due to the previous character, the LIS is flexible, useable, elastic and able to support the dynamic application.

  • Needs of our society for information professional have been changed continuously. The purpose of this paper is to study a direction of Library and information Science(LIS) education which can response properly the change. For this purpose, 1) the characteristics of information socitey, the demand to information profession, and the qualification required by the emerging job market of information professionals are examined. 2) the identity of LIS and its educational achievement for information professionals are considered. 3) Information Resources Management (IRM) which in some sense shares the common goal of effective information transfer with LIS is also considered. 4) the similarities and the differences between the two are discussed to seek their interrelationship and cooperation possibiity. While there are differences in focus and practice between LIS and IRM, interdisciplinary partnership between these two can enhance theory and practice of each other's area. Particulary, LIS school can take advantage for their students to penetrate the emerging job market as well-rounded information professionals.

  • The purpose of the study is to identify the perception of the Library and Information Science (LIS) specialists about the use of mobile phones in retrieving information. It investigates the present status of the LIS specialists regarding mobile phone usage, perceptions regarding the use of mobile phones in retrieving information from libraries and points out the possible drawbacks and their solutions for embracing mobile phones in retrieving information from libraries and providing some suggestions. The methodology includes a quantitative approach. The authors used a survey method using a structured questionnaire to measure the perception of LIS specialists regarding the use of mobile phones in retrieving information from libraries. The findings confirmed that the majority (72%) of LIS specialists have the experience of using mobile phones for more than 10 years. Findings also indicate that the LIS specialists have agreed with the statements of advantages of using mobile phones. This paper concludes that the respondents also agreed regarding the possible advantages of introducing mobile phones in retrieving information from libraries. The paper explores the original perceptions of LIS specialists regarding the use of mobile phones in retrieving information from libraries.
