The main objective of this study is to investigate the importance of three compositions in multimedia for learning outcomes (LOs) in relation to individual differences in short-term memory (STM) capacity. The study is based on a survey of 378 individuals at the bachelor level (military officers, teachers, and psychology students). The LOs of three different multimedia compositions (means) were tested. This applied to individuals with low, medium, and high STM capacity. The results show that the successive presentation (Type II) of learning materials through multiple representation forms/channels (speech, pictures, and screen text/labels) provides a better LO than just speech (Type I) and simultaneous presentation (Type III). Overall, visual and verbal channel capacities did not contribute to the LO in any of the three tools tested, but some specific STM capacity types or substructures (visual and verbal progressive capacities) and non-verbal (RAPM) types have significance, particularly in exploiting successive presentation (Type II) for learning. Although the tools used in the multimedia educational material had a low cognitive load, the individuals with low capacity learned relatively less than the individuals with higher capacity. A symbolic form of expression was introduced concerning the relationship between cognitive load structure (CLS) and LOs through various tools in multimedia as an aid in the theoretical and empirical analyses. This is referred to as the CLS-LO formula. The main assumption of this study, based on previous empirical and theoretical ones, is that the relationship between CLS and LO is expressed with the following CLS-LO formula: CLSTypeIII>CLSTypeII>CLSTypeI→LOTypeIII>LOTypeI>LOTypeII. Based on this study, the relationship became: CLSTypeIII>CLSTypeI>CLSTypeII→LOTypeII>LOTypeI=LOTypeIII. This basic research study is primarily a contribution to understanding underlying cognitive processes in STM and their importance for learning in multimodal forms compared with analogue text. The findings will also be relevant as a basis for performance analysis and decision-making under high information pressure, risk, and unpredictable conditions.

This chapter aims to reexamine the relationship between Turkish prospective teachers' thinking styles and creativity fostering behaviors. In the study, 182 Turkish prospective teachers were participated. The Thinking Styles Inventory (TSI) and Creativity Fostering Teacher Index Scale (CFTIS) were administered to participants. An exploratory factor analysis, zero order and partial correlation, linear and quadratic trend analysis were conducted on the data. The results indicated that Type I thinking styles are a more powerful predictor for creativity fostering behaviors than Type II thinking styles. Prospective teachers' implicit opinions about creativity negatively predicted to CFTIS. Relationship between Type I and Type II thinking styles, and creativity fostering behaviors were positively significant in the results of quadratic trend analysis; however, the relationship between implicit opinions about creativity and creativity fostering behaviors were negatively significant in the analysis. The results obtained from the study were discussed based on previous studies.

AbstractAn advanced Mendelian Cannabis breeding program has been developed utilizing chemical markers to maximize the yield of phytocannabinoids and terpenoids with the aim to improve therapeutic efficacy and safety. Cannabis is often divided into several categories based on cannabinoid content. Type I, Δ 9-tetrahydrocannabinol-predominant, is the prevalent offering in both medical and recreational marketplaces. In recent years, the therapeutic benefits of cannabidiol have been better recognized, leading to the promotion of additional chemovars: Type II, Cannabis that contains both Δ 9-tetrahydrocannabinol and cannabidiol, and cannabidiol-predominant Type III Cannabis. While high-Δ 9-tetrahydrocannabinol and high-myrcene chemovars dominate markets, these may not be optimal for patients who require distinct chemical profiles to achieve symptomatic relief. Type II Cannabis chemovars that display cannabidiol- and terpenoid-rich profiles have the potential to improve both efficacy and minimize adverse events associated with Δ 9-tetrahydrocannabinol exposure. Cannabis samples were analyzed for cannabinoid and terpenoid content, and analytical results are presented via PhytoFacts, a patent-pending method of graphically displaying phytocannabinoid and terpenoid content, as well as scent, taste, and subjective therapeutic effect data. Examples from the breeding program are highlighted and include Type I, II, and III Cannabis chemovars, those highly potent in terpenoids in general, or single components, for example, limonene, pinene, terpinolene, and linalool. Additionally, it is demonstrated how Type I – III chemovars have been developed with conserved terpenoid proportions. Specific chemovars may produce enhanced analgesia, anti-inflammatory, anticonvulsant, antidepressant, and anti-anxiety effects, while simultaneously reducing sequelae of Δ 9-tetrahydrocannabinol such as panic, toxic psychosis, and short-term memory impairment.

AbstractBackground and purposeModic changes (MC) are bone marrow and vertebral endplate lesions seen in magnetic resonance imaging (MRI) which have been found to be associated with low back pain (LBP), but the association between MC and health-related quality of life (HRQoL) is poorly understood. The aim of this study was to assess the relationship between MC and HRQoL among patients referred to spine surgery.MethodsThe study population consisted of 181 patients referred to lumbar spine surgery in Northern and Eastern Finland between June 2007 and January 2011. HRQoL was assessed using RAND-36 health survey. Lumbar MC were evaluated and classified into ‘No MC’, ‘Type I’ (Type I or I/II), and ‘Type II’ (Type II, II/III or III).ResultsIn total, 84 patients (46%) had MC. Of these, 37% had ‘Type I’ and 63% ‘Type II’. Patients with MC were older, more likely females, had longer duration of LBP and a higher degree of disc degeneration than patients without MC. The total physical component or physical dimensions did not differ significantly between the groups. The total mental component of RAND-36 (P = 0.010), and dimensions of energy (P = 0.023), emotional well-being (P = 0.012) and emotional role functioning (P = 0.016) differed significantly between the groups after adjustments for age and gender. In the mental dimension scores, a statistically significant difference was found between ‘No MC’ and ‘Type II’.ConclusionsAmong patients referred to spine surgery, MC were not associated with physical dimensions of HRQoL including dimension of pain. However, ‘Type II’ MC were associated with lower mental status of HRQoL.ImplicationsOur study would suggest that Type II MC were associated with a worse mental status. This may affect the outcome of surgery as it is well recognized that patients with depression, for instance, have smaller improvements in HRQoL and disability. Thus the value of operative treatment for these patients should be recognized and taken into consideration in treatment. Our study shows that MC may affect outcome and thus clinicians and researchers should be cognizant of this and take this into account when comparing outcomes of surgical treatment in the future. A longitudinal study would be needed to properly address the relationship of MC with surgical outcome.

The investigation of this isolated epidemic of meningococcus meningitis at a C.C.C. camp gave an opportunity to examine the carrier state in contacts carrying what were presumably virulent epidemic strains of organisms. With the aid of Miller's technique for the enhancement of the demonstrable virulence of meningococci for mice, it proved possible to test the virulence of the carrier strains from Camp Rusk. These results were consistent despite the interval of from 3 to 4 weeks which intervened between the isolation of the strains and the virulence titrations. Type I strains were found to have a high virulence, while the virulence of Type II strains was moderately high but definitely less than that of the Type I, and atypical strains and strains of N. catarrhalis isolated from carriers showed a very low virulence. The question of the precise nature of the carrier state was investigated. No evidence has been obtained yet as to the existence of a relationship between pharyngitis, coryza or upper respiratory disease and the presence and degree of the carrier state. This is unlike the situation with regard to pneumococcus carriers. On the other hand, it has proved possible to demonstrate reactions within the body to the meningococci in the nasopharynx, consisting of the formation of agglutinins and protective antibodies in the blood serum. 32.3 per cent of Type I and 60 per cent of Type II carrier sera showed moderate or good agglutinins for homologous organisms and 80 per cent of Type I and 40 per cent of Type II sera showed moderate or good protective antibodies against virulent homologous strains. No idea could be obtained as to the relationship of the presence or absence and the degree of serological reaction and the duration of the carrier state.

AbstractProperties of n-GaN/p-SiC and n-AlGaN/p-SiC heterojunctions prepared by HVPE on 4H SiC substrates were studied by means of C-V, C/G-T, C-f, I-V and DLTS. It is shown, in agreement with earlier publications, that the GaN/p-SiC HJ is staggered type II with ΔEc=-0.4 eV andΔEv=0.6 eV. Whenchanging GaN for AlGaN with Al mole fraction of x=0.25-0.3 the band alignment becomes normal type I with ΔEc=0.2 eV andΔEv=0.6 eV. I-V characteristics of both heterojunctions bear evidence of strong tunneling via defect states, particularly centers with activation energy of 1.25 eV for GaN/4H SiC HJ. The tunneling was found to be more pronounced in the AlGaN/SiC HJs even though these HJs showed no evidence of formation of dark line defects at the interface, in contrast to GaN/SiC. DLTS measurements on both types of HJs revealed the presence of broad bands whose behavior is indicative of these bands being related to continuous states in the gap, most likely near the nitride/carbide interface.

Background and Purpose: The aim of this study was to compare the different subtypes of anterior choroidal artery (AChoA) aneurysm based on a new classification and to analyze the risk factors according to individual endovascular treatment (EVT).Methods: In the new classification, AChoA aneurysms are classified into independent type (I type) and dependent type (II type) based on the relationship between the AChoA and the aneurysm. II type aneurysms have three subtypes, IIa (neck), IIb (body), and IIc (direct). We retrospectively analyzed 52 cases of AChoA aneurysm treated in our center between 2015 to 2019. There were 13 (25.0%) I type aneurysms, 24 (46.2%) IIa aneurysms, 15 (28.8%) IIb aneurysms, and no IIc type; 28 cases had a subarachnoid hemorrhage. According to our preoperative EVT plan for the different subtypes: II type should achieve Raymond-Roy Occlusion Class 1 (RROC 1) where possible. To protect the AChoA, it is best to preserve the neck of the IIa type aneurysms (RROC 2), and RROC 3 is enough for IIb type.Results: Ten asymptomatic cases with minimal aneurysms were treated conservatively. Of the other cases, 42 were treated with individualized EVT (26 with a simple coil, 6 with balloon-assisted coiling, 7 with stent-assisted coiling, and 3 by flow diverter. Different subtypes had different RROC (Z = 14.026, P = 0.001). IIb type aneurysms (χ2 = 7.54, P = 0.023) were one of the factors related to temporary or permanent AChoA injury during surgery. Overall, two patients (IIa = 1, IIb = 1) developed contralateral hemiparesis.Conclusions: The new classification diagram clearly shows the features of all types of AChoA aneurysm and makes EVT planning more explicit. The II type (particularly IIb) was a potential risk factor for AChoA injury.

The Relationship

Apoptosis is a highly organized form of cell death that plays an important regulatory role in many biological processes. The relationship between the two classical signalling pathways of apoptosis, the “death receptor” and “mitochondrial” pathways, was only vaguely appreciated until 1998, when death receptor pathway-mediated activation of the mitochondrial pathway was clearly demonstrated for the first time. The “type I/type II” model of death receptor-mediated apoptosis was proposed and subsequently adopted for use in categorizing cells according to the involvement of the mitochondrion duringdeath receptor-induced apoptosis. Since that time, however, different interpretations of the type I/type II cell definition have appeared in the literature and, consequently, the meaning of type I and type II cells has become less clear.L’apoptose est une forme de mort cellulaire très structurée qui joue un rôle important de régulation dans un grand nombre de processus biologiques. La relation entre les deux voies de signalisation traditionnelles de l’apoptose, la voie des « récepteurs de mort » et la voie mitochondriale, n’était connue que vaguement avant 1998, l'année où l’activation de la voie mitochondriale par l’intermédiaire de la voie des récepteurs de mort a été clairement démontrée pour la première fois. Le modèle « type I / type II » d’apoptose par l’intermédiaire des récepteurs de mort a été proposé puis adopté auxfins de catégorisation des cellules en fonction de la participation des mitochondries à cette apoptose. Depuis, différentes interprétations ont toutefois été formulées dans des ouvrages scientifiques quant à la définition des cellules de type I et de type II et, par conséquent, la signification de « cellules de type I » et de « cellules de type II » est devenue moins évidente.

Abstract OBJECTIVE. We investigated the relationship between Lund-Mackay scale, olfactory bulb depth and width, and Keros classification in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). MATERIAL AND METHODS. In this retrospective study, paranasal sinus computed tomography (PNSCT) images of 47 patients with CRSwNP and 47 healthy subjects (control) were evaluated. In the CRSwNP group, PNSCT scans were assessed based on Lund-Mackay scale. In both groups, olfactory fossae (OF) depth and width, and Keros classification were evaluated. RESULTS. The total Lund-Mackay score was 17.1±5.9. There were no significant differences between OF depth and width values of the nasal polyps group and control group. For both groups, Type II Keros was the most detected type; secondly, Keros type I and rarely Keros type III were detected. There was no significant correlation between Lund-Mackay score (All items and total score) and OF depth and width, and Keros type. There were negative correlations between ipsilateral OF depth and width (p<0.05), whereas there were positive correlations between contralateral OF depth and width (p>0.05). Keros type was positively correlated between ipsilateral and contralateral OF depth and Keros type (p<0.05). In older patients, left OF depth and Keros type decreased (p<0.05). CONCLUSION. As a conclusion, there was no correlation between Lund-Mackay score and olfactory fossa dimensions (depth and width). When considering age, one could notice that Keros type decreased in older patients.

Working memory, our ability to work with information, plays an important role in learning from kindergarten to the college years. In this article, we review the what, the why, and the how of working memory. First, we explore the relationship between working memory, short-term memory, and long-term memory. We also investigate research on the link between whether environmental factors, such as financial background and mother's educational level, affect working memory. In the next section — the why of working memory — we compare the predictive nature of working memory and IQ in learning outcomes. While IQ typically measures the knowledge acquired by the student, working memory measures what they do with that knowledge. Working memory skills are linked to key learning outcomes, including reading and math. In the final section, we present classroom strategies to support working memory. We also review current research on the efficacy of working memory training.
