The results of research investigating differences in matrix completion abilities between low-SES and middle-SES children have been inconsistent. This study provided a framework in which several unresolved issues could be examined. Item type, order of presentation, training modes, and developmental level were varied in two SES groups in an attempt to clarify previous research findings. The subjects were 288 individually tested children. SES level was determined by the Hollingshead and Redlich (1958) scale while developmental level was represented by first, third, and fifth grade levels. Training consisted of maximal prompt, correctness-of-response feedback, and a no-training-control condition. Subject responded to double classification and enclosure matrix completion item types until a criterion performance was obtained, and were then shown 11 transfer items of each type. The results revealed significant SES, grade, and training main effects. Generally, middle-SES and older subjects were able to learn more efficiently and transfer more effectively than their counterparts. SES and training interacted with item type and order of presentation which indicated differential facilitative effects across SES levels. A major finding was the absence of a significant SES X grade interaction. This result supports a developmental lag as opposed to Level I Level II interpretation.

Diabetes is characterized by depressed cardiac functional properties attributed to Ca2+-activated ATPase activity. In contrast, endurance swimming enhances the cardiac functional properties and Ca2+-activated myofibril ATPase. Thus, the purpose of this study was to observe if the changes associated with experimental diabetes can be ameliorated with training. Diabetes was induced with a single i.v. injection of streptozotocin (60 mg/kg). Blood and urine glucose concentrations were 802 ± 44 and 6965 ± 617 mg/dL, respectively. The training control and training diabetic animals were made to swim (±2% body weight) 4 days/week for 8 weeks. Cardiac myofibril, at 10 μM free Ca2+ concentration was reduced by 54% in the sedentary diabetics compared with sedentary control animals (p < 0.05). Swim training enhanced the Ca2+-activated myofibril ATPase activities for the normal animals. The diabetic animals, which swam for 8 weeks, had further reduced their Ca2+-activated myofibril ATPase activity when compared with sedentary diabetics (p < 0.05). Similarly, the Mg2+-stimulated myofibril ATPase activity was depressed by 31% in diabetics following endurance swimming. It is concluded that the depressed Ca2+-activated myofibril ATPase activity of diabetic hearts is not reversible with endurance swimming.

The present study looks at in-patient nursing service at Garut Regional Public Hospital dr. Slamet and patient satisfaction as viewed from the gap between service performance and patient expectations. Using a descriptive approach, the influence of in-patient nursing service on patient satisfaction was analyzed. Research data were collected through observation and questionnaires addressed to the patients. The results of the study lead to a conclusion that patients were satisfied with the in-patient nursing care they received. It is suggested that the hospital improve their responsiveness to patient complaints, provide information in simple and easy to understand language, improve the skills of medical personnel by providing regular education and training, improve patient safety and trust, improve service personnel skills such as knowledge in using disease diagnostic tools, hospitality skills, and communication skills.

We investigated perceptual learning in 85 healthy adults with stereoscopic information contained in dynamic random dot stimuli or with vernier targets. Stimuli were flashed simultaneously at 8 locations at an eccentricity of 1.15° or 2.3°, and subjects had to detect a target in an “8 Alternative Forced Choice” task. For training at a given eccentricity stimuli at the other eccentricity served as a “no training” control. Viewing of visual targets for about 20 minutes resulted in a significant increase of discrimination performance only for the trained stimuli (significant interaction between training and time). Thus, learning is position specific: improved performance can be demonstrated only when test and training stimuli are presented to the same retinal areas. In combination with our earlier electrophysiological results, this study illustrates how perceptual training induces stimulus and visual field specific neural plasticity in adults.

Politicians, societies, stakeholders, health care systems, patients, their relatives, their employers, and the general population need to know what they can expect from clinical psychologists. Even more, for our self-definition as a professional group, we should share a common understanding of the competence profile that characterises our qualifications. This understanding of the competence profile of clinical psychology leads directly to the content that should be taught in university curricula and postgraduate trainings for clinical psychology. The following discussion paper attempts to offer a general European framework for defining the competence profile of clinical psychologists. A group of European specialists developed this discussion paper under the umbrella of the European Association of Clinical Psychology and Psychological Treatment (EACLIPT). Representatives with different treatment orientations, of basic science and clinical applications, and from East to Western European countries, were part of the group. We present a list of competences that should be acquired during regular studies of psychology with a clinical specialisation. Additionally, further competences should be acquired either during studying, or during postgraduate trainings. Clinical psychologists are experts in mental and behavioural disorders, their underlying psychological, social and neurobiological processes, corresponding assessments/diagnostic tools, and evidence-based psychological treatments. While we provide a list with all competences of clinical psychologists, we do not consider this proposal as a final list of criteria, but rather as a living discussion paper that could be updated regularly. Therefore, we invite our colleagues to contribute to this discussion, and to submit comments via email to the corresponding author. People need to know what they can expect from clinical psychologists. We present a list of competences that clinical psychologists acquire during their training. This list of competences was developed by colleagues representing different treatment orientations, different European countries, and basic versus clinical scientists. This competence list can represent a basis for optimising education and training programmes for clinical psychologists, and for informing the public.

The purpose of this study is to examine the effect of periodized core training program on the serve velocity in male tennis players aged 11-13 years. 24 male nationally ranged (age 11.9±1.63, height 154.4±11.32, weight 43±8.76) participated to the study from a professional tennis club. Pre-post-training - control group design was applied and subjects were randomly assigned to Control Group and Training Group. Training Group participated to the core training program consisted of isometric and isotonic core stabilization exercises on stable and nonstable surfaces, three days in a week for 8 weeks in addition to tennis training sessions. Accurate service velocity, was assessed initially and at the end of the 8-week core program for both control and training groups. There was a significant improvement (6.6 %) in the serve velocity for the training group after the experiment, whereas there were no differences in the control group. Core stabilization training improved service velocity for young tennis players. It is recommended tennis coaches to apply periodized core stabilization exercises to young athletes and plan training programs in this way. Extended English abstract is in the end of PDF (TURKISH) file. ÖzetBu çalışmanın amacı 11-13 yaş arası erkek tenisçilerde periyodlanmış core antrenman programının isabetli servis hızına etkisini incelemektir. Çalışmaya profesyonel bir tenis kulübünden ulusal müsabık 24 erkek tenisçi (yaş 11.9±1.63, boy 154.4±11.32, ağırlık 43±8.76) katılmıştır. Araştırmada ön-test son-test kontrol gruplu model uygulanmış, denekler iki gruba rastgele atanmıştır. 12 sporcu Kontrol Grubunu, 12 sporcu ise Deney Grubunu oluşturmuştur. Deney Grubuna haftanın üç günü yarım saatlik 8 hafta boyunca toplamda 24 antrenman birimi stabil ve stabil olmayan yüzeylerde izometrik ve izotonik core stabilizasyon egzersizlerinden oluşan program, tenis antrenmanlarına ek olarak uygulanmıştır. Program öncesi ve sonrasında her katılımcı maksimal hızda 10 servis kullanarak en hızlı ve geçerli atışları kaydedilmiştir. Core antrenman uygulaması sonrası Kontrol Grubunun servis atış hızı değişmezken, Deney Grubu servis atış hızını ortalama 120.93 km/s hızdan 128.6 km/s hıza (% 6.6) çıkarmıştır. Core antrenman uygulamalarının genç tenisçilerde isabetli servis hızını olumlu etkilediği tespit edilmiştir. Tenis antrenörlerinin yüksek şiddet içermeyen, core antrenmanlarını ve stabilizasyon uygulamalarını genç sporcularda uygulamasının yararlı olacağı düşünülmekte ve antrenman programlarını buna göre planlamaları tavsiye edilmektedir.

Coronavirus disease 2019 (COVID-19) has been spread out all over the world. Although a real-time reverse-transcription polymerase chain reaction (RT-PCR) test has been used as a primary diagnostic tool for COVID-19, the utility of CT based diagnostic tools have been suggested to improve the diagnostic accuracy and reliability. Herein we propose a semi-supervised deep neural network for an improved detection of COVID-19. The proposed method utilizes CT images in a supervised and unsupervised manner to improve the accuracy and robustness of COVID-19 diagnosis. Both labeled and unlabeled CT images are employed. Labeled CT images are used for supervised leaning. Unlabeled CT images are utilized for unsupervised learning in a way that the feature representations are invariant to perturbations in CT images. To systematically evaluate the proposed method, two COVID-19 CT datasets and three public CT datasets with no COVID-19 CT images are employed. In distinguishing COVID-19 from non-COVID-19 CT images, the proposed method achieves an overall accuracy of 99.83%, sensitivity of 0.9286, specificity of 0.9832, and positive predictive value (PPV) of 0.9192. The results are consistent between the COVID-19 challenge dataset and the public CT datasets. For discriminating between COVID-19 and common pneumonia CT images, the proposed method obtains 97.32% accuracy, 0.9971 sensitivity, 0.9598 specificity, and 0.9326 PPV. Moreover, the comparative experiments with respect to supervised learning and training strategies demonstrate that the proposed method is able to improve the diagnostic accuracy and robustness without exhaustive labeling. The proposed semi-supervised method, exploiting both supervised and unsupervised learning, facilitates an accurate and reliable diagnosis for COVID-19, leading to an improved patient care and management.
