Published: March 2022

The reaction of Co(OAc)2·4H2O with multisite coordinated salamo-based ligand H2L containing six coordinating sites in presence of co-ligand NCS- anions afforded successfully a trinuclear Co(II) complex [Co3(L)2(NCS)2]. The trinuclear Co(II) complex has been characterized by elemental analyses, UV-visible, Fourier transform infrared spectroscopic methods and DFT calculation. In addition, the structure of the Co(II) complex has been confirmed by single crystal X-ray crystallography. X-ray crystal structure analysis of the Co(II) complex revealed that the Co(II) complex consists of three Co(II) atoms coordinated by two fully deprotonated ligand (L)2- units and co-ligand NCS- anions. The close surveillance of the crystal structure of the Co(II) complex discloses some notable non-covalent interactions like H-bonding, C-H···π and π···π. The luminescent property of the Co(II) complex has been studied in methanol solution. Apart from, as a complementary revelation, intermolecular interactions with respect to percentages of hydrogen bondings in the X-ray crystal structure of the trinuclear Co(II) complex was quantified by analyses of Hirshfeld surfaces and fingerprint plots.

Introduction: Measurement of skin temperature with infrared thermometry has been utilised for assessing metabolic activity and may be useful in identifying patients with ulcers suitable for hyperbaric oxygen treatment and monitoring their treatment progress. Since oxygen promotes vasoconstriction in the peripheral circulation, we hypothesised that oxygen administration may lower skin temperature and complicate the interpretation of temperatures obtained. This pilot study investigated the effect of oxygen administration on lower limb skin temperature in healthy subjects and diabetic patients. Methods: Volunteers were recruited from healthy staff members (n = 10) and from patients with diabetic foot ulcers (n = 10) at our facility. Foot skin surface temperatures were measured by infra-red thermometry while breathing three different concentrations of oxygen (21%, 50% and 100%). Results: Skin temperature changes were observed with increasing partial pressure of oxygen in both groups. The mean (SD) foot temperatures of diabetic patients and healthy controls at air-breathing baseline were 30.1°C (3.6) versus 29.0°C (3.7) respectively, at FiO2 0.5 were 30.1°C (3.6) versus 28.5°C (4.1) and at FiO2 1.0 were 28.3°C (3.2) versus 29.2°C (4.3). None of these differences between groups were statistically significant. Conclusions: Data from this small study may indicate a difference in thermal responses between healthy subjects and diabetic patients when inhaling oxygen; however, none of the results were statistically significant. Further investigations on a larger scale are warranted in order to draw firm conclusions.

Introduction: Intractable haemorrhagic cystitis (HC) is a serious complication of chemotherapy (CT) and haematopoietic stem cell transplantation (HSCT). Hyperbaric oxygen treatment (HBOT) is a promising treatment option based on the similarities in injury pattern and observed histological changes with radiation induced HC, which is an approved indication. We present our experience with HBOT in HC occurring after CT and HSCT. Methods: Medical files of patients who underwent HBOT between the years 2000-2020 for HC that developed after chemotherapy and/or HSCT were reviewed. Demographic data, primary diagnosis, history of HC and details of HBOT were documented. Treatment outcomes were grouped as complete and partial healing, no response and deterioration. Results: Twenty-five patients underwent a median of 12 HBOT sessions for HC occurring after CT and HSCT. Complete healing was observed in 11 patients whereas haematuria improved in seven patients. HC grades after HBOT were significantly better than referral grades. A significant correlation was shown with the number of HBOT sessions and change in haematuria. Patients who underwent seven or more HBOT sessions benefitted most. Conclusions: HBOT appears to be a safe and effective treatment for refractory HC following CT and HSCT. Higher quality evidence would be needed to prove efficacy. However, given the difficulty of conducting randomised controlled trials on such a vulnerable and small group of patients with few treatment options, and given the consistency of current observational evidence, HC occurring after CT and HSCT may be considered as an optional or investigational indication for HBOT.

Nowhere is redundancy more indispensable than extended range cave diving. Training and practice in this discipline ensure divers are equipped with backup regulators, gauges, lights, and adequate breathing gas for a safe exit, emergencies, and decompression. Depending on penetration distances and depth, open circuit cave diving may require carrying more gas cylinders than can be logistically managed by the diver themselves while maintaining safe gas supply margins. Consequently, divers are forced to either stage cylinders in the cave prior to the dive or rely on resupply from support divers. Both scenarios have significant drawbacks. Due to the improved efficiency of breathing gas utilisation and other advantages, closed circuit rebreathers (CCR) have enabled extended range cave diving. With increasing depths, penetration distances, and bottom times, these divers must also plan for an increasing amount of open circuit bail-out gas in the event of CCR failure. Staged cylinders have traditionally been utilised, but this strategy has limitations due to the advanced dives needed to place them and equipment degradation due to prolonged water immersion, which can often result in cylinder and regulator corrosion with consequent leakage of contents over time. Consequently, a growing number of CCR divers are foregoing open-circuit bailout altogether by carrying an additional CCR system for bailout. Although these bailout rebreathers may facilitate further exploration and have certain advantages, the risks of diving with two complex machines remain to be clearly defined.

Introduction: SARS-CoV-2 (COVID-19) was declared a global pandemic on 11 March 2020 and has become a serious threat to public health. As it can easily be transmitted through droplets and aerosols, there is an increased risk of transmission in enclosed environments such as hyperbaric oxygen treatment (HBOT) units if preventive measures are not taken. Case report: A 16-year-old female tested positive for SARS-CoV-2 during HBOT for idiopathic sudden sensorineural hearing loss. The other patients and the inside attendant who attended the sessions with her were regarded as contacts, tested for SARS-CoV-2, and quarantined until the test results were available. Ultimately, none of them tested positive. Discussion: As HBOT in multiplace chambers entails a high risk of SARS-CoV-2 transmission, we strictly adapted our practice to consider that every patient could be a potential asymptomatic carrier. Therefore, the negative results of all contacts in this case and the fact that no confirmed cases of COVID-19 were reported suggests that these measures successfully prevented SARS-CoV-2 transmission in our HBOT clinic. SARS-CoV-2 transmission can be prevented if sufficient protective measures are taken.
A diving physician’s experience of dental barotrauma during hyperbaric chamber exposure: case report

Previous cases of dental barotrauma have been reported in pilots and divers. We report a case of dental barotrauma and barodontalgia in a diving physician accompanying patients during hyperbaric oxygen treatment, and due to pressure changes in the hyperbaric chamber. The physician developed sharp pain localised to the right maxillary molars but radiating to the face, ear and head during decompression from 243 kPa (2.4 atmospheres absolute). The pain intensified following completion of decompression and was consistent with irreversible pulpitis. Clinical examination and panoramic radiography suggested fracture of a heavily restored tooth due to barotrauma. This was managed by tooth extraction. The physician subsequently discontinued accompanying the patients during their hyperbaric oxygen treatment sessions. Dentists and maxillofacial surgery specialists suggest waiting for a minimum of four weeks or until the tooth socket and/or oral tissue has healed sufficiently to minimise the risk of infection or further trauma before exposure to further pressure change. Although seemingly rare, and despite the comparatively slow pressure changes, dental barotrauma can occur in hyperbaric chamber occupants.

Massive amounts of data gathered over the last decade have contributed significantly to the applicability of deep neural networks. Deep learning is a good technique to process huge amounts of data because they get better as we feed more data into them. However, in the existing literature, a deep neural classifier is often treated as a ”black box” technique because the process is not transparent and the researchers cannot gain information about how the input is associated to the output. In many domains like medicine, interpretability is very critical because of the nature of the application. Our research focuses on adding interpretability to the black box by integrating Formal Concept Analysis (FCA) into the image classification pipeline and convert it into a glass box. Our proposed approach pro- duces a low dimensional feature vector for an image dataset using autoencoder followed by a supervised fine-tuning of features using a deep neural classifier and Linear Discriminant Analysis (LDA). The low dimensional feature vector produced is then processed by FCA based classifier. The FCA framework helps us develop a glass box classifier from which the relationship between the target class and the low dimensional feature set can be derived. Further, it helps the researchers to understand the classification task and refine it. We use the MNIST dataset to test the interfacing between deep neural networks and the FCA classifier. The classifier achieves an accuracy of 98.7% for binary classification and 97.38% for multi-class classification. We compare the performance of the proposed classifier with Convolutional neural networks (CNN) and Random forest.

İyi Niyetli Şehzade ve Kötü Niyetli Şehzade Hikayesinde İyi-Kötü Göstergelerinin Dil-Söz Bağlamında İncelenmesi
Authors: GÖKKAPLAN Yusuf
Published: March 2022

Türk topluluklarının din etkisi ile dünyaya bakış açısında önemli değişiklerin gerçekleştiği dönemlerden biri de Uygur Dönemi’dir. Bu dönemde oluşan yeni kültürü; yeni bir din ve onun gereklilikleri çevresinde oluşturulmuş, Türk topluluklarının eski gelenek, yaşantı ve kültürleriyle beraber yoğrulmuş bir sentez olarak değerlendirebiliriz. Bu yeni kültür, bu dönemde ortaya konmuş olan yazınsal türlere hem içerik hem de ifade biçimi olarak katkı sağlamış ve zengin bir yazınsal türün oluşmasına zemin hazırlamıştır. Bu yazınsal tür sadece din ve kültür motiflerinin yer aldığı, toplumsal düzen ile ilgili söyleyişlerin ifade edildiği metinler değildir. Bu metinlerle aynı zamanda bir uygarlığın dünya görüşü ve hayat felsefesi de ifade edilmiştir. Uygur döneminde bu düşünce ve felsefe ile ortaya konan eserlerden biri de İyi Niyetli Şehzade ve Kötü Niyetli Şehzade hikayesidir.

Bu öyküde iyilik ve kötülük gibi iki zıt kavram, karakterlerin dünya görüşü ve hayatı algılama biçimi çerçevesinde anlatılmıştır. Bu çalışmada bu iki zıt kavram Saussure’nin dil-söz kuramı ile ele alınacaktır. Bir dilbilimci olan Saussure’ün dil bilimi anlayışı dil (langue) ve söz (parole) ayrımı üzerinden daha iyi anlaşılabilir. Saussure göre söz, dilin somut kullanımıdır; uygulanışıdır. Dil ise onu belirleyen, arka plandaki toplumsal yapıdır; sistemdir. Saussure, dil ve sözü homojen bir bütünlük oluşturan kavramlar olarak ele almaz, yapısı gereği ikisinin aynı teoriyle çözümlenemeyecek farklılıklar taşıdığına dikkat çeker ve ayrı olarak incelenmesi gerektiğini belirtir. Bu bakış açısından hareketle, bu metindeki iyi ve kötü kavramlarının arkasındaki derin yapı ifade edilmeye çalışılacaktır.
The Effects of Atmospheric and Pressure Frying Processes on the Quality Characteristics of Meatballs
Authors: ŞİŞİK OĞRAŞ Şeyma
Published: March 2022

In the study, it was aimed to determine the effect of atmospheric and pressure frying on some quality properties of meatballs. For this purpose, meatballs have been subjected to deep frying process using hazelnut oil in atmospheric and pressure conditions. Fried meatball samples were analyzed in terms of pH, % moisture, TBARS (thiobarbutyric acid reactive substance), and instrumental color (internal and external surface). The meatballs were also tested for their instrumental texture properties. The frying factor had a significant effect (p˂0.05) on the moisture value and a very significant effect (p˂0.01) on the TBARS value of meatballs. The % moisture values of the samples fried in atmospheric conditions were determined lower than the samples fried in pressurized conditions. The pressure frying process reduced the TBARS value and increased the L *, a *, and b * values of the internal surface. This method resulted in an increase in the L * value and a decrease in the b * value in the external surface (p˂0.05). The frying repeat factor generally caused a decrease in the internal and external surface colors. The pressure frying process increased the hardness, adhesiveness, resilience, and cohesiveness values of the meatball samples. However, the frying method did not have a significant effect on the springiness (p˃0.05). The frying number caused a decrease in all texture parameters except the gumminess value.
Effects of Salinity on Yield, Yield Components and Water Productivity of Black Carrot (Daucus Carota L.) Under Water Stress Condition
Authors: ALTUN Mehmet , ARSLAN Hakan
Published: March 2022

Salinity and drought are some of the main problems affecting global crop yields. In this study, interaction effects of irrigation interval and salinity on yield, soil salinity, other parameters of black carrot were evaluated in a covered rain shelter. The treatments consist of three different irrigation intervals (4 days (I1), 6 days (I2), and 8 days (I3) with 6 different irrigation water salinity levels (0.38 (S1), 1.5 (S2), 3.0 (S3), 5.0 (S4) 7.0 (S5) and 10.0 (S6) dS m-1. The results indicated that the effect of interaction between irrigation interval and salinity was significant on yield, evapotranspiration, chlorophyll content, and soluble solid content (SSC). Yield and evapotranspiration decreased significantly with an increase in salinity and irrigation intervals. The highest yield was observed in I1S1, and the yield response (Ky) in the black carrot was 1.39. The irrigation water salinity up to 1.5 dS m-1 was nonsignificant on yield. However, the increase in soil salinity by 1 dS m-1 caused a decrease of 3.83%, 2.93%, and 3.03% in the yields of I1, I2, and I3, respectively. Moreover, increasing the salinity of irrigation water reduced the chlorophyll content and carrot juice pH value. The result of the study indicated that black carrot is sensitive to salt and water deficit, and the maximum irrigation interval using saline water should not be more than 6 days. Therefore, it can be concluded that in regions where salinity is high, more frequent irrigation minimizes losses that may occur in yield.

Published: March 2022

This study was carried out in Diyarbakır conditions with 20 advanced triticale lines and 5 standard varieties in 2012-2013 and 2013-14 growing seasons. According to variance analysis results, the interaction of year, genotype and year*genotype was found to be significant (p<0.01; p<0.05) in terms of many characteristics. the results showing that plant height was changed 3 237-5 389 kg/ha-1, hectoliter weight is 71.2-78.8 kg/hl-1, thousand grain weight is 28.0-40.2 g, protein content 14.6%-17.2%, the moisture rate in the grain varied between 7.9-8.1%. In terms of traits, many lines used in the research were superior to the varieties used as standard in the experiment. In addition, superior genotypes were determined by considering all characters together with GT biplot technique. In GT biplot technique, PC1 made up 36.83% of the variation, PC2 constituted 19.53% of the variation and 56.36% of the variation in total. According to the results of the research, depending on the ecological factors of the growing seasons, the plants were earlier spiked and reached higher height in the first year; It was determined that grain yield, thousand grain weight and hectoliter weight were higher than the second year, and on the contrary, the protein content was lower than the second year due to high precipitation. It was concluded that biplot analysis techniques facilitate the work of breeders in selection. It has been concluded that the results of a single growing season will be insufficient and the results of two growing seasons may be sufficient to evaluate the cultivar candidates.

Published: March 2022

The effect of nanoemulsions based on rosemary essential oil (BNE) and its purified version (BEO) on the growth of fish spoilage bacteria (P. luteola, P. damselae, V. vulnificus, E. faecalis, S. liquefaciens, and P. mirabilis) and foodborne pathogens (S. Paratyphi A, S. aureus, K. pneumoniae, and E. faecalis) and their biogenic amine formation were investigated in tyrosine decarboxylase broth (TDB) using HPLC method. The flavour compounds of extracted BEO were determined using GC-MS. Physical properties of BNE (viscosity, thermodynamic stability, droplet size, and surface tension) were analysed. Tween 80, BEO, and BNE were inhibitory effects on the growth performances of the pathogenic and spoilage bacteria. Differences in ammonia (AMN) and biogenic amine (BA) production among groups were statistically significant (p<0.05). The highest HIS production was obtained by spoilage E. faecalis (58.76 mg L-1) and the lowest by V. vulnificus (2.29 mg L-1). Almost all other BAs such as PUT, CAD, SPD, and PHEN were formed by pathogens and spoilage groups. S. aureus (143.05-702.88 mg L-1) was the main high tyramine (TYR) producer in TDB. HIS production by V. vulnificus was considerably suppressed in the presence of BNE (p<0.05). Although the effect of treatment groups (Tween 80, BEO, and BNE) varied depending on the bacterial strain and specific amine, all groups generally decreased AMN and BA accumulation by bacteria. Consequently, the results show that all bacteria tested are capable of decarboxylating more than one amino acid and conversion of rosemary oil into nanoemulsion suppressed BA production activity and its nano-form can be used as an alternative antimicrobial agent in processed or packaged fish or food products.

In this study, it was aimed to determine the medium where Lactobacillus fermentum microorganisms with probiotic properties grow most efficiently by using Response Surface Method (RSM). Studies have been conducted on a 500 ml erlenmeyer scale, the medium optimization of the Lactobacillus fermentum strain was carried out according to the Central Composite Design (CCD) included in RSM. The effects of glucose, yeast extract, inorganic salts, and Tween 80 were investigated on the growth rate of the L. fermentum NBC-08 strain. Samples were taken at regular intervals from the erlenmeyer flask and the number of viable cells was measured by planting them in petri agar medium. In the study, the number of viable cells log10 (cfu/ml) was chosen as the response variable. As a result of the study, it was concluded that glucose and yeast extract are absolutely essential components in the medium. The optimum medium composition was found as 96.06 g/L glucose, 40.76 g L-1 yeast extract, 19.43 g L-1 inorganic salts, and 11.01 ml/L Tween 80. The production of the maximum L. fermentum strain was determined as 10.75 log10 (cfu ml-1). It is predicted that this study will make positive contributions to the fermentation conditions and medium optimization studies for production of lactic acid bacteria
Information-seeking processes of junior high school students: A case study of CD-ROM encyclopedia use
Authors: Branch Jennifer
Published: March 2022

The purpose of this research was to examine the information-seeking processes employed by junior high school students from Inuvik, Northwest Territories, Canada when using CD-ROM encyclopedias. The study revealed that participants needed both instruction and practice to develop the skills and strategies needed for full-text searching of CD-ROM encyclopedias. The participants tended to use search terms only from the original question, had difficulty selecting topics and articles from the retrieved list, and did not read long articles as carefully as short articles. Instruction related to information-seeking skills and strategies should focus on generating search terms, selecting topics from a retrieved list, and skimming and scanning through text to find the answer.

Integration of evidence-based library and information practice into school library education: A case study
Authors: Cahill Marcia , Richey Jennifer
Published: March 2022

Evidence-based library and information practice (EBLIP) provides an avenue toward success for school library programs. This case study explored school library certification students' understandings of, experiences with, and potential applications of EBLIP within the context of a school library management course. Findings suggest students had limited experiences with EBLIP in school library settings. Study of EBLIP over the course of a semester increased students' understanding of the concept. Students recognized the importance of EBLIP for the development, improvement, and sustainability of school library programs.

Published: March 2022

The School of Information Studies at Syracuse University has long been an innovator in library and information science education, including the establishment of the field's first Web-based with limited residencies library and information science distance learning program in 1993. This article describes Syracuse's school library education (both distance and campus-based) in terms of developing student competence through a competency-based curriculum, bringing research into the classroom, and the use of technology for teaching and learning; fostering creativity through inquiry and "scholarship in action"; and building a community of inquiry among school library faculty, students, and practitioners through the use of social media and a variety of inclusive techniques.
The school library of today: Guises and "universal" roles
Authors: Shenton Andrew , Marshman Gwyneth
Published: March 2022

In recent years, the disappearance of traditional libraries from Britain's schools has attracted strong criticism. This paper explores how the computer-oriented information environments that have replaced them do, however,share similarities with old-style book areas. Specifically, each: (a) connects users with information, (b) offers resources that are available to everyone, (c) incorporates structures that demonstrate how large collections of information may be organized, (d) forms a space for developing and practicing information skills, (e) provides a welcoming environment for all, (f) unites pupils of different ages, and (g) may afford access to staff who support the learning process. The paper concludes by suggesting that, irrespective of the nature of the "library", the existence of an intermediary who can discharge a range of teaching and learning functions is crucial.

Going the Extra Mile: What Makes School Librarians Proactive?
Authors: Streatfield David , Rienties Bart , Markless Sharon , Rae-Scott Simon
Published: March 2022

This paper reports on a second round of analysis (conducted in 2012-13) of the results of the national surveys of UK school libraries completed in 2010, involving self-eported activities and priorities of 803 school librarians. This further analysis highlighted four aspects of proactive school library manager behaviour relating to their approaches to: promoting reading for pleasure, information literacy development, collaborating with teachers , and actively exploiting ICT within the school. Various levers or drivers that are associated with proactive library managers were then identified from the survey findings. These are: supervision by senior managers and ready access to them; active development planning; the library manager's academic and professional qualifications. The relative strengths of each of these drivers were assessed from the data.
Are we leaving them lost in the woods with no breadcrumbs to follow? Assessing signage systems in school libraries
Authors: Johnston Melissa P. , Mandel Lauren H.
Published: March 2022

In order to successfully navigate space in seeking information, students need to develop their spatial thinking, or the ability to visualize and interpret location, distance, direction, relationships, movement, and change through space. Learning to think spatially has been defined as a vital skill for students to be equipped properly for their future (National Research Council, 2006; National Science Foundation, 2010). Wayfinding refers to the ability of users of the built environment (i.e., a facility) to navigate through that environment to find specific destinations (Mandel, 2010). In the school library environment this means that student users can find and access the information they need for school related tasks and assignments.
A Research Agenda for Enhancing Teacher Librarians' Roles and Practice in Hong Kong's 21st Century Learning Environments
Authors: Lo Patrick , Yu Kelly , Chiu Dickson
Published: March 2022

In many countries, especially countries in Asia, there has always been a lack of understanding on the role of the teacher librarians. Through the results of interviews with two professionally recognized teacher librarians in Hong Kong, we define some enhancing roles and best practices of teacher librarians in the Asia that merit further exploration. Because previous empirical studies have been small and quantitative, this qualitative study highlights key topics in a proposed research agenda that focuses on current and emerging issues of teacher librarianship in the digital age.
A Place to Learn or a Place for Leisure? Students' Use of the School Library in Norway
Authors: Rafste Elisabeth Tallaksen
Published: March 2022

The aim of this article is to present findings about how students in Norway use and value the school library as part of their daily practice in school, and who those users are. Data were collected through observations, interviews, and questionnaires in two case-study schools (16-18-year-old students) for six months. The findings indicate that students use and value the school library more as a social meeting place and a place for pleasure than as a place for education-related studies. The data are discussed within a theoretical frame of sociology and domain-specific socialization theories and describe the library as a porous space in the school.
Student Learning Through Ohio School Libraries, Part 2: Faculty Perceptions of Effective School Libraries
Authors: Todd Ross , Kuhlthau Carol C
Published: March 2022

This article focuses on the perceptions of school principals and teaching faculty in relation to the school library and the helps it provides to students. Set against a brief review of current literature, it examines data provided by 879 faculty in 39 elementary, middle, and high schools in Ohio as part of the Student Learning Through Ohio School Library research study. In a parallel survey to the Impacts on Learning Survey for students participating in this research, the Perceptions of Learning survey sought to gather faculty's perceptions of the helps provided by the school library to their students. This article presents a summary of the findings, provides a brief comparison with the student data, and addresses the concept of evidence of school library helps as observed by the teaching faculty.
An Analysis of Information Literacy Education Worldwide
Authors: Moore Penny
Published: March 2022

This article was prepared for UNESCO, the United States National Commission on Libraries and Information Science, and the National Forum on Information Literacy, for use at the Information Literacy Meeting of Experts, Prague, The Czech Republic. The author explores some of the factors that facilitate and hinder the drive toward information literacy around the world, as reflected in publications of the International Association of School Librarianship (IASL) between 1998 and 2002. Initiatives taken in the compulsory schooling sector are illustrated with reference to the degree of existing literacy and technological infrastructure in particular countries, together with differing understandings of information literacy. The transition from literacy to information literacy and school library programs, promising practices in addressing students' learning needs, and those of their teachers are explored. Promising government initiatives are outlined, and recommendations for future progress are made.
School Libraries in Bhutan: Birth of a Reading Culture
Authors: Shaw Felicity
Published: March 2022

Modernization of Bhutan began in 7962, with the launching of the country's first five-year development plan. In 1963, the government invited a Canadian Jesuit educationist. Father William Mackey, to come to Bhutan to help establish a secular school system. This article briefly sketches the development of a modern education system and early attempts at library provision, and then studies in detail the ongoing School Library Development Project that is being implemented with funding support from donor agencies and through World Bank-funded (but education sector-inspired) development projects. Significant achievements in library development and reading promotion activities are being brought about through the vision and commitment of career education officers working closely with sympathetic donor agency counterparts toward the realization of longstanding goals.
Korea: A Study of School Library Development
Authors: Han Yoon-ok
Published: March 2022

Until the 1990s, school libraries were a low priority in the South Korean educational system. But the Korean government has now developed a five-year master plan for improving school libraries. Similarly, the government has undertaken significant educational reform in order to cultivate creative human resources through open education and lifelong learning. The implementations of these educational reforms are based on information and communication technology (ICT) in education and the seventh educational curriculum. In addition to these policies, the activity of NGOs has been effective in developing school libraries. Today, South Korea has a modern, well-developed school library system.
Information Policy for Hong Kong Schools: The Case of the Missing Chopsticks
Authors: Henri James , Lee Sandra , Alan Chan
Published: March 2022

A project to develop a research instrument to study information policy in schools was conducted. Part of that study, a literature review and a Hong Kong-based study, was completed to benchmark information policy practice in schools in Hong Kong. The authors found that information policy at a macro level was well addressed in the literature as governments addressed a quagmire of intellectual property, intellectual freedom, security, privacy, and administrative issues. Information policy at the micro level-in schools-was lacking. The purpose of this study was to investigate how the micro-level set of information policies is handled in schools. An online questionnaire administered to in-service teachers in Hong Kong provided findings that reinforced the authors' initial feeling that information policy is a topic more talked about than understood. It is worth pursuing comparisons using the instrument with information policy development in other countries.
The School as an Information Ecology: A Framework for Studying Changes in Information Use
Authors: Perrault Anne Marie
Published: March 2022

This article explores the concept of the school as information ecology and proposes the use of this concept as a framework for studying the dynamics of online information-seeking behaviors of educators within the ecology. From an earlier study of teachers' online information-seeking behaviors using online survey and interview methods, four themes emerged: currency of information, sparking of ideas and gaining personal knowledge, resource management and the role of time, and webs of sharing. However, although teachers were using the Internet widely, they were underusing the online digital tools pecifically designed for educational use.
School Libraries in Sri Lanka: A State-of-the-Art Report
Authors: Yapa Geetha
Published: March 2022

School libraries in Sri Lanka are moving toward a period of rapid growth and development due to an ambitious program developed by the Ministry of Education and Higher Education. Although librarianship is not new to Sri Lankans, the development of school libraries has been slow due to lack of funds and trained personnel. The government has taken the initiative of reorganizing the system of education to meet the challenges of the 21st century, and as part of this the school libraries will also be improved to provide better learning environments to the students. This article highlights the changes that are currently being implemented toward reaching this goal.
