Dancers' motions are perceived by observers through visual processes with visual information forming the basis for the observers' appreciation and evaluation of the dancers' motions. There have been many discussions as to whether or not observers' personal athletic capabilities form an essential basis for accurate assessment of the motions of others but, so far, no valid conclusions have been reached. The purpose of this study is to investigate how the ability to predict motions of others varies depending on the athletic expertise of the observers. Participants of this research were ballet dancers of varying athletic expertise. Twenty seven participants were divided into three groups with nine in each: beginners, intermediate experts and experts. The participants watched the same dance video and then evaluated whether the motion would be successful or not. The movement related visual information required to evaluate the success of the motion was systematically adjusted by controlling the length of the video. Using the temporal occlusion method, this study measured the response accuracy of the participants by category of expertise. Under the circumstance with insufficient visual information to utilize, the experts showed higher rates of correct response than the intermediate experts and the beginners. The beginners showed higher rates of wrong response than the experts and the intermediate experts. These results showed that the ability to predict success or failure of a dance motion varied depending on motion expertise of the observers, although they had similar level of expertise in perception. Participants considered to have high athletic expertise showed high prediction ability on the result of the motion. In addition, high expertise in perception reduced the likelihood that participants would make hasty responses under the circumstance with insufficient information and helped to reduce wrong response rate. In conclusion, this study showed that motor expertise and perceptual expertise contribute to prediction accuracy of observed motions.

Hearing loss in newborns is the most frequently occurring birth defect. If hearing impaired children are not identified and managed early, it is difficult for many of them to acquire the fundamental language, social and cognitive skills that provide the foundation for later schooling and success in society. All newborns, both high and low risk, should be screened for hearing loss in the birth hospital prior discharge (Universal Newborn Heaing Screening, UNHS). Objective physiologic measures must be used to detect newborns and very young infants with hearing loss. Recent technological developments have produced screening methods and both evoked otoacoustic emission (EOAE) and auditory brainstem response (ABR) have been successfully implemented for UNHS. Audiologic evaluation should be carried out before 3 months of age and infants with confirmed hearing loss should receive intervention before 6 months of age. All infants who pass newborn hearing screening but who have risk indicators for other auditory disorders and/or speech and language delay receive ongoing audiologic surveillance and monitoring for communication development. Infants with sensorineural hearing loss are managed with hearing aids and receive auditory and speech-language rehabilitation therapies. Cochlear implants can be an outstanding option for certain children aged 12 months and older with severe to profound hearing loss who show limited benefit from conventional amplifications.

Prospective memory (PM) is related to remember to carry out a previously intented behaviour. The purpose of this study was to develop a paradigm for measuring PM function to diagnosis in mild cognitive impairment 1 or brain injury in patients 2. among brain injured patients Thirty-eight normal healthy subjects participated in current study. The paradigm was composed of four conditions: a baseline and three intention conditions (expectation, execution 1 and 2). In the expectation condition, subjects were asked to make a new response to intented stimuli during ongoing task, but the intented stimuli never occurred. In the execution 1 (one type of expected stimulus) and 2 (two types of expected stimuli), the intended stimuli did occur in 20% of trials. The reaction time and error rate were calculated in each condition. Repeated measures using ANOVA of subject's mean reaction times (RTs) and mean error rates (ERs) showed main effects of conditions during ongoing task. The comparison of PM tasks in executive condition 1 and 2 also showed significance in RTs and ERs. This paradigm reflects sufficiently the performance of prospective memory function during ongoing task in normal individuals. Thus, we suggest that the paradigm will be helpful to study neural network of PM function using brain imaging techniques and diagnosis of PM dysfunction.

Internet-of-Things (IoT) becomes one of the most promising future paradigms, which foresees enormous amounts of interoperable things and heterogeneous services. The goal of IoT is to enable all things connected and brings all kinds information and services to people. However, such a great deal of information may lead to cognitive overload or restrain in productivity of people. Thus, it is a necessity to build intelligent mechanisms to assist people in accessing the information or services they needed in a proactive manner. Most of previous related mechanisms are built on well-defined web services and lack of consideration of constrained resources. This paper suggests a services composition method by adapting a hierarchical model, which is a graph-based model composed of four layers: Context Layer, Event Layer, Service Layer and Device Layer. With a such multi-layer graph, service composition can be achieved by the iteration of layer by layer. Then, to evaluate the effectiveness of this proposed hierarchical model, a real-life emergency response dataset is applied and the experimental results are composed with the general probabilistic method and indicate that the proposed method is help for compositing multiple services while considering given context and constrained resources.

This study is to examine the effects of salespeople' attributes (i.e., empathy, availability, professional appearance) on consumer cognition, emotion, and behavior. A conceptual model was developed based on stimulus-organism-response (S-O-R) theory and cognition-emotion theory. A total of 542 questionnaires were collected online and some incompletely written questionnaires were excluded. Because of the high possibility of memory distortion, only the questionnaires (n=220) written by those who visited fashion stores within one week were used for the final analysis. The results of PLS analyses demonstrated that 1) salespeople's empathy directly affected consumers' shopping emotion; 2) salespeople's availability and professional appearance indirectly affected consumer's shopping emotion through store image; 3) consumers' shopping emotion positively affected purchase intention. Theoretical and practical implications of the results are discussed in conclusion. As a result of this research, the main characteristics of the salespeople were identified in order to allow the consumers visiting the fashion store to buy the fashion products naturally and the basic directions of sales manuals for the salespeople in the fashion store were presented. It is also hoped that academic researchers will be able to use the characteristics of salespeople as the main data to understand how they affect consumers' cognitive and emotional responses and how they are connected to purchase behavior.

Miliary brain metastasis from the lung is uncommon and has a poor therapeutic response. We report a case of pulmonary adenocarcinoma combined with multiple brain cystic lesions that were initially misdiagnosed as neurocysticercosis. A 53-year-old male who never smoked was admitted to our hospital with complaints of agitation and cognitive impairment. Brain magnetic resonance imaging showed innumerable, small nodular lesions with a central, low signal intensity in whole brain parenchyma. His symptoms were not improved by the empirical praziquantel medication for disseminated neurocysticercosis. After a transbronchial biopsy from the right middle lobe, we could diagnose the primary lung adenocarcinoma with a single nucleotide polymorphism in the epidermal growth factor receptor exon 20 at codon 787 (Q787Q). His neurologic symptoms and imaging findings have been gradually improving with a first-line Gefitinib treatment for five months. We recommend a more active diagnostic approach including biopsy in case of atypical imaging findings.

This research aimed 1) to analyze the relationship between consumer's emotional needs and elements of textile design in the 1st survey 2) to investigate textile design process presently conducted in the industry in the 2nd survey, and 3) to suggest a desirable direction to improve the textile design process based on a comparison of the results obtained from the two surveys. A description system and an emotion model on textile design were redeveloped as research devices in this study. In the 1st survey, total 600 respondents were sampled and asked to report their emotional response on 50 representative types of textile design, on a emotion measurement scale. The data set obtained from the 1st survey were statistically analyzed. In the 2nd survey, a depth interview was applied to qualitatively analyze the textile design process presently conducted in the industry. The results from the two surveys were compared.

Hypertension is one of the most common chronic diseases in childhood and adolescence. Untreated hypertension adversely affects many organs including heart, brain, kidney and peripheral arteries. We reviewed the complication of central nervous system caused by pediatric hypertension. Cerebral blood flows are maintained constantly in response to changes in blood pressure by cerebral autoregulation. Severe hypertension which destructs cerebral autoregulation results in acute hypertensive encephalopathy syndrome, ischemic or hemorrhagic stroke. Chronic pediatric hypertension induces learning disability and cognitive defect which are subclinical symptom prior to brain damage caused by severe hypertension. We should consider the effect of hypertension on pediatric brain because appropriate antihypertensive drugs could prevent these complications.

P300 is widely used as a neurophysiological indicator of cognitive processing, which is known as reflecting controlled processing. MMN (mismatch negativity), early response prior to P300, is known as reflecting an early stage of information processing and having involuntary attention and automatic awakening or sensory memory. This study for normal people shows that electric potential of P300 and MMN are in close correlation (r=-0.673, p<0.05). That is, it is observed that the higher negative value electric potential of MMN measured at cerebral forehead-center has, the higher value electric potential of P300 measured at cerebral center-vertex has. This fact implies that working memory for temporary storage and operation of stimuli, and involuntary attention which constitute automatic information processing, an early stage of information processing, play a crucial role in efficient information processing. On the other hand, considering that MMN of cerebral forehead-center and P300 of cerebral center-vertex are in close correlation, it is necessary to pursue further study of cerebral parts which generate P300 and MMN in information processing.

The system performance of Engineered Safety Features is of utmost importance in a nuclear power plant. The human performance is identified as most critical to assurance of the optimal operability of safety systems during an emergency. The aim of this study is to determine how the performance of safety system could be evaluated using Augmented Reality technology. The paper presents a description of how a systems engineered approach could be used to develop the necessary operating conditions needed to conduct this measurement. Augmented Virtual Reality (AVR) interface technology is achieving ease of availability and widespread use in many applications today as illustrated by the launch of several AR and VR devices aimed at media consumption. As such, environments that incorporate such AVR hardware have become invaluable tools in designing human interface systems because of the high fidelity and intuitive response to natural human interaction that can be achieved [2]. The outcome of the measurement undertaken is to determine whether 1.) Operator(s) performance can be enhanced by introducing an improved cognitive method of monitoring plant information during an Emergency Operating Procedures (EOP) and 2.) In correlation, inform the performance of the diverse safety systems on the basis of human factors.
