WILLIAMS, MICHAEL D. 이화여자대학교 국제통상협력연구소 2001 Jounal of APEC Studies Vol.3 No.1

Recent changes to the Singapore education system have moved particularly rapidly in the area of the use of computer technologies in schools, and have produced marked demands on teachers to upgrade their technology skills and practices to meet this new educational environment. This paper describes the process which the Singapore education profession, especially pre-service teacher preparation, has undergone in the past several years in an effort to prepare teachers to integrate information and communications technologies (ICT) into their teaching and learning. A variety of factors producing these changes is presented, followed by an updated set of ICT competencies for teachers, as well as the response by the Singapore National Institute of Education to meet these new professional requirements.

Many human studies suggest a benefit of tea consumption on bone health. The study objective was to compare the ability of different tea types to promote mineralization. Saos-2 cells underwent mineralization (5 days) in the presence of tea (white: WT, green: GT, black: BT, green rooibos: GR, or red rooibos: RR; 1 μg/mL of polyphenols) or control. Total polyphenol content (TPC, Folin-Ciocalteu's reagent), antioxidant capacity (2,2-diphenyl-1-picrylhydrazyl [DPPH] scavenging), mineralization (Alizarin Red staining), gene expression quantitative reverse transcription PCR (RT-qPCR), and cell activity (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay) were determined. TPC was highest in GT and BT. The ability of each tea to inhibit DPPH also differed (WT, GT > RR) after normalizing for polyphenol quantity. Each tea increased mineralization and differences were observed among types (GT/BT/GR/RR > WT, GT = BT = GR, RR > BT/GT). mRNA expression of alkaline phosphatase (ALP) and ectonucleotide pyrophosphatase/phosphodiesterase (NPP1) remained unchanged, whereas osteopontin (OPN) and sclerostin (SOST) were reduced in cells treated with tea, regardless of type. At 24- and 48-h postexposure to tea, cell activity was greater in cells receiving any of the teas compared with vehicle control. Supplementation increased mineralization regardless of tea type with both rooibos teas and black tea stimulating greater mineralization than WT, whereas green tea is similar to the others. While future study is needed to confirm in vivo effects, the results suggest that consuming any of the teas studied may benefit bone health.

Background: The purpose of this study was to evaluate the functional outcomes, infection rate, and complications associated with shoulder arthroplasty for sequelae of prior septic arthritis. Methods: This is a retrospective cohort study of 17 patients who underwent shoulder arthroplasty for sequelae of septic arthritis. Patients were analyzed for patient-reported outcomes, complications, and reoperations. Results: The 17 patients in this cohort were an average age of 65.4 ± 12.2 years old, were 58.8% male, and had an average body mass index of 27.9 ± 4.1 kg/m2. These patients underwent 14 reverse shoulder arthroplasties (RSAs; 11 after antibiotic spacer placement), one anatomic total shoulder arthroplasty after antibiotic spacer placement, and two hemiarthroplasties (both after antibiotic spacer placement). Two patients underwent reoperation (dislocated RSAs). There were four complications (23.5%): two RSA dislocations, one acromial stress fracture, and one atraumatic rotator cuff tear after hemiarthroplasty. There were no cases of postoperative wound complications or infection. At an average of 4.1 ± 1.8 years of follow-up for all 17 of 17 cases, the average visual analogue scale pain score was 4.6 ± 2.3, average Single Assessment Numeric Evaluation Score was 59.3 ± 23.7, average American Shoulder and Elbow Surgeons Score was 57.6 ± 15.5, and average Simple Shoulder Test was 6.9 ± 2.6 based on “yes” responses. Conclusions: Shoulder arthroplasty after septic arthritis had inconsistent functional outcomes and high complication rates but no reinfection.

Forisome based biomimetic smart materials

B.D. Hamlington,Winfried S. Peters,Amy Q. Shen,Michael Knoblauch,William F. Pickard 국제구조공학회 2006 Smart Structures and Systems, An International Jou Vol.2 No.3

With the discovery in plants of the proteinaceous forisome crystalloid (Knoblauch, et al. 2003), a novel, non-living, ATP-independent biological material became available to the designer of smart materials for advanced actuating and sensing. The in vitro studies of Knoblauch, et al. show that forisomes (2-4 micron wide and 10-40 micron long) can be repeatedly stimulated to contract and expand anisotropically by shifting either the ambient pH or the ambient calcium ion concentration. Because of their unique abilities to develop and reverse strains greater than 20% in time periods less than one second, forisomes have the potential to outperform current smart materials as advanced, biomimetic, multi-functional, smart sensors or actuators. Probing forisome material properties is an immediate need to lay the foundation for synthesizing forisome-based smart materials for health monitoring of structural integrity in civil infrastructure and for aerospace hardware. Microfluidics is a growing, vibrant technology with increasingly diverse applications. Here, we use microfluidics to study the surface interaction between forisome and substrate and the conformational dynamics of forisomes within a confined geometry to lay the foundation for forisome-based smart materials synthesis in controlled and repeatable environment.

Optimal Flow Experience In Web-Based Instruction

lju Rha,Michael D. Williams,Gyun Heo 서울대학교 교육연구소 2005 Asia Pacific Education Review Vol.6 No.1

The purpose of this study is to explore learner engagement and motivation related to Flow particularly in WBI settings. In the Flow state people are absorbed in their activities while irrelevant thoughts and perceptions are screened out. In this article, we attempted to identify some of the critical elements of learner feelings and WBI features which relate to the experience of Flow. Survey data were collected from 266 Korean cyber-university students and the data were subject to factor analyses and multiple regression to determine the best predictors of Flow in WBI environments. As a result, six factors, including G-factor for flow, were found. Based on these findings, a theoretical model for Learner Flow within WBI was proposed.

Ballasting and deballasting of shipping vessels in foreign ports have been reported worldwide as a vector of introduction of non-native aquatic plants and animals. Recently, attention has turned to ballast water as a factor in the global increase of harmful algal blooms (HABs). Many species of microalgae, including harmful dinoflagellate species, can remain viable for months in dormant benthic stages (cysts) in ballast sediments. Over a period of four years, we surveyed ballast water and sediment of ships docked in two ports of Tampa Bay, Florida, USA. Sampling conditions encountered while sampling ballast water and sediments were vastly different between vessels. Since no single sample collection protocol could be applied, existing methods for sampling ballast were modified and new methods created to reduce time and labor necessary for the collection of high-quality, qualitative samples. Five methods were refined or developed,including one that allowed for a directed intake of water and sediments. From 63 samples, 1,633 dinoflagellate cysts and cyst-like cells were recovered. A native, cyst-forming, harmful dinoflagellate, Alexandrium balechii (Steidinger) F. J. R. Taylor, was collected, isolated, and cultured from the same vessel six months apart, indicating that ships exchanging ballast water in Tampa Bay have the potential to transport HAB species to other ports with similar ecologies, exposing them to non-native, potentially toxic blooms.

Use of Dietary Management in Irritable Bowel Syndrome: Results of a Survey of Over 1500 United States Gastroenterologists

( Adrienne Lenhart ),( Courtney Ferch ),( Michael Shaw ),( William D Chey ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2018 Journal of Neurogastroenterology and Motility (JNM Vol.24 No.3

Background/Aims Dietary therapy is increasingly used to manage gastrointestinal (GI) symptoms in patients with irritable bowel syndrome (IBS). We aim to gauge United States gastroenterologists’ perceptions of dietary therapies for IBS. Methods We distributed a 22-question survey to members of the American College of Gastroenterology. The survey was developed by gastroenterologists and survey methodologists. We collected information pertaining to demographics, providers’ interpretation of their patients’ views on dietary therapy, and gastroenterologists’ perceptions on dietary therapy, and nutritional counseling in IBS. Results One thousand five hundred and sixty-two (14%) surveys were collected. Nearly 60% of participants reported that patients commonly associate food with GI symptoms. IBS patients most commonly use a trial and error approach followed by a lactose-free and glutenfree diet, and rarely use a low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet on their own. Over half of providers recommend diet therapy to > 75% of IBS patients and most commonly recommend a low FODMAP diet. Only 21% of gastroenterologists commonly refer IBS patients to registered dietitians, and only 30% use GI dietitians. Female providers were more likely than males to recommend dietary changes as the primary mode of therapy (OR, 1.43 [1.09-1.88]; P = 0.009). Conclusions Our national survey identified enthusiasm for diet treatment of IBS. While patients infrequently tried a low FODMAP diet on their own, GI providers commonly recommended this diet. Only a minority of GI providers refer their IBS patients to a registered dietitian for nutrition counseling and few refer patients to dietitians with specialized GI training. Female providers were more enthusiastic about diet therapies than males. (J Neurogastroenterol Motil 2018;24:437-451)
