Globally, the COVID-19 pandemic has impaired every aspect of life, especially causing much psychological damage—for instance, increasing risk suicide. Intense fear and anxiety are considered to play a central role in mental health problems. This study examined properties Japanese version Fear Scale (FCV-19S) using classical test theory (CTT) item response (IRT). Five hundred fifty participants ...

Task modelling has proven useful as a basis for user interfaces (IU) design. Although different models have been pushed ConcurTaskTrees (CTT) notation has become without any doubt the most extended notation for task model specification. However, this notation suffers from a lack of modularity, making the creation and modification of real-world applications a cumbersome process. In this paper a ...

Despite the fact that the deployment of sensor networks and target tracking could both be managed by taking full advantage of Voronoi diagrams, very little few have been made in this regard. In this paper, we designed an optimized barrier coverage and an energy-efficient clustering algorithm for forming Vonoroi-based Wireless Sensor Networks(WSN) in which we proposed a mobile target tracking sc...

The purpose of the study was to determine comparability of an online version to the original paper-pencil version of Defining Issues Test 2 (DIT2). This study employed methods from both Classical Test Theory (CTT) and Item Response Theory (IRT). Findings from CTT analyses supported the reliability and discriminant validity of both versions. Findings from IRT analyses confirmed that both version...

Medical Surgical Nursing is one of the major subjects in nursing. This study examined the validity and reliability of the achievement examination utilizing the Classical Test Theory and Item Response Theory. The study answered the following objectives specifically : ( a) To establish the validity and reliability of the achievement examination utilizing Classical Test Theory and Item Response Th...

Detection of foreign materials is the first step of successful immune responses. Stimulator of interferon genes (STING) was shown to directly bind cyclic diguanylate monophosphate (c-di-GMP), a bacterial second messenger, and to elicit strong interferon responses. Here we elucidate the structural features of the cytosolic c-di-GMP binding domain (CBD) of STING and its complex with c-di-GMP. The...

The purpose of this study is to develop Education Value Perception Scale (EVPS) based on Bronfenbrenner's Ecological Theory and investigate its psychometric properties according Classical Test (CTT) Item Response (IRT). data were collected from 2872 secondary school students by stratified purposeful sampling method. Measurement invariance EVPS was tested multigroup confirmatory factor analysis ...

A limited-area survey of the η Chamaeleontis cluster has identified 2 new late-type members. The more significant of these is ECHA J0843.3–7905 (= IRAS F08450– 7854), a slowly-rotating (P = 12 d) M2 classical T Tauri (CTT) star with a spectrum dominated by Balmer emission. At a distance of 97 pc and cluster age of ≈ 9 Myr, the star is a nearby rare example of an ‘old’ CTT star and promises to b...

Merocyanine (MC) isomers that are formed after absorption of a UV photon by 1',3'-dihydro-1',3'-3'-trimethyl-6-nitrospiro[2H-1-benzopyran-2',2'-(2H)-indole] were studied. Several, predominantly TTC and TTT, merocyanine isomers are present in toluene solution ("T" and "C" indicate trans and cis conformations of the C-C bonds in the methine bridge). Excitation in the MC visible absorption band (a...
