Abstract Evaluators must understand the complex overall process that makes up an independent medical evaluation (IME), whether the purpose of the evaluation is to assess impairment or other care issues. Part 1 of this article provides an overview of the process, and Part 2 [in this issue] reviews the pre-evaluation process in detail. The IME process comprises three phases: pre-evaluation, evaluation, and postevaluation. Pre-evaluation begins when a client requests an IME and provides the physician with medical records and other information. The following steps occur at the time of an evaluation: 1) patient is greeted; arrival time is noted; 2) identity of the examinee is verified; 3) the evaluation process is explained and written informed consent is obtained; 4) questions or inventories are completed; 5) physician reviews radiographs or diagnostic studies; 6) physician records start time and interviews examinee; 7) physician may dictate the history in the presence of the examinee; 8) physician examines examinee with staff member in attendance, documenting negative, physical, and nonphysiologic findings; 9) physician concludes evaluation, records end time, and provides a satisfaction survey to examinee; 10) examinee returns satisfaction survey before departure. Postevaluation work includes preparing the IME report, which is best done immediately after the evaluation. To perfect the IME process, examiners can assess their current approach to IMEs, identify strengths and weaknesses, and consider what can be done to improve efficiency and quality.

The advancement in the development of computer technology has led to the idea of human computer interaction. Research experiments in human computer interaction involves the young age group of people that are educated and technically knowledgeable. This paper focuses on the mental model in Human Computer Interaction. There are various approaches of this review paper and one of them is highlighting current approach, results and the trends in the human computer interaction and the second approach is to find out the research that have been invented a long time before and are currently lagging behind. This paper also focuses on the emotional intelligence of a user to become more user like, fidelity prototyping. The development and design of an automated system that perform such task is still being accomplished.

A continual pressure within the educational system in Indonesia to focus on high levels of academic achievement is a major barrier to implementing an effective physical education curriculum in Indonesia. The conflict between the implementation of a movement based approach (MBA) and a sport based approach (SBA) presents another continuing problem. The current approach leads more to an orientation towards the acquisition of sport skills rather than the attainment of objectives of cognitive development. This study is aimed to reveal the association between the physical fitness and academic achievement of children in Sumedang, West Java. Four physical fitness test items and a specially constructed mathematics test were administered to 265 children from grades four and five. The ability of performance on the physical fitness tests to predict performance in mathematics was calculated by linear multipleregression analysis. The findings revealed that there was a significant association, although low, between the physical fitness components and mathematics achievement. Sit ups and squat jumps showed low partial correlations and the relationships for push ups and the 400 metre run were negative Limitations in the ability of the children to perform the tests were suggested as an explanation for the mixed results. It was argued that this weakness served to emphasise the importance of giving greater priority to physical education and the quality of its teaching within the school curriculum.

Melanoma is on the first place in mortality among all skin tumors. Over the past 50 years, there has been a steady increase in the incidence of cutaneous melanoma compared to other types of tumors. Rates of 5-year survival are fairly high, if melanoma is diagnosed in the early stages, which requires adequate diagnostics and treatment. Melanoma diagnostic, especially in the early stages, can be problematic even for an experienced dermatologist. However, primary contact doctor can be any specialty. Melanoma and other skin tumors can be detected by physical examination during treatment for another disease. Phenotypic risks factors, anamnestic data, and physical examination data are important in cutaneous melanoma diagnostics. The sensitivity of clinical diagnosis during a visual examination by an experienced dermatologist is approximately 70 percent. However, dermascopy can significantly increase the accuracy of a clinical diagnostics. In recent years there has been an active research for new non-invasive methods and algorithms for cutaneous melanoma diagnostics. The main goal of non-invasive diagnostics is to determine need for biopsy. This decision should be based on a combination of clinical and dermascopic examinations and other information, including growth dynamics, symptoms and medical history. Thus, an adequate diagnostic of cutaneous melanoma, including non-invasive and invasive methods, is a simple and economically viable way to early detection of cutaneous melanoma and to reduce mortality from this aggressive disease.

AbstractFood synergy concept is suggested to explain observations that isolated antioxidants are less bioactive than real foods containing them. However, mechanisms behind this discrepancy were hardly studied. Here, we demonstrate the profound impact of interactions between two common food flavonoids (individual: aglycones quercetin—Q and naringenin—N− or their glycosides rutin—R and naringin—N+ vs. mixed: QN− and RN+) on their electrochemical properties and redox-related bioactivities. N− and N+ seemed weak antioxidants individually, yet in both chemical and cellular tests (DPPH and CAA, respectively), they increased reducing activity of mixtures synergistically. In-depth measurements (differential pulse voltammetry) pointed to kinetics of oxidation reaction as decisive factor for antioxidant power. In cellular (HT29 cells) tests, the mixtures exhibited properties of a new substance rather than those of components. Pure flavonoids did not influence proliferation; mixtures stimulated cell growth. Individual flavonoids tended to decrease global DNA methylation with growing concentration; this effect was more pronounced for mixtures, but not concentration-dependent. In nutrigenomic studies, expression of gene set affected by QN− differed entirely from common genes modulated by individual components. These results question the current approach of predicting bioactivity of mixtures based on research with isolated antioxidants.

Abstract Biomass ashes like rice husk ash (RHA), bagasse fly ash (BFA), were used for aqueous phase removal of a pesticide, diuron. Response surface methodology (RSM) and artificial neural network (ANN) were successfully applied to estimate and optimize the conditions for the maximum diuron adsorption using biomass ashes. The effect of operational parameters such as initial concentration (10–30 mg/L); contact time (0.93–16.07 h) and adsorbent dosage (20–308 mg) on adsorption were studied using central composite design (CCD) matrix. Same design was also employed to gain a training set for ANN. The maximum diuron removal of 88.95 and 99.78% was obtained at initial concentration of 15 mg/L, time of 12 h, RHA dosage of 250 mg and at initial concentration of 14 mg/L, time of 13 h, BFA dosage of 60 mg respectively. Estimation of coefficient of determination (R 2) and mean errors obtained for ANN and RSM (R 2 RHA = 0.976, R 2 BFA = 0.943) proved ANN (R 2 RHA = 0.997, R 2 BFA = 0.982) fits better. By employing RSM coupled with ANN model, the qualitative and quantitative activity relationship of experimental data was visualized in three dimensional spaces. The current approach will be instrumental in providing quick preliminary estimations in process and product development.

Abstract The so-called ‘Big Mess Construction’ (BMC) frustrates standard assumptions about the structure of nominal groups. The normal position of an attributive adjective is after the determiner and before the noun, but in the BMC, the adjective precedes the determiner, e.g. that strange a sound, so big a scandal, too lame an excuse. Previous accounts of the BMC are couched in ‘Phrase Structure Grammar’ (PSG) and view the noun or the determiner (or the preposition of) as the root/head of the BMC phrase. In contrast, the current approach, which is couched in a ‘Dependency Grammar’ (DG) model, argues that the adjective is in fact the root/head of the phrase. A number of insights point to the adjective as the root/head, the most important of which is the optional appearance of the preposition of, e.g. that strange of a sound, so big of a scandal, too lame of an excuse.
