ABSTRACT
Objective To explore and establish accurate detection quality control method of source positioning and timer precision for afterloading equipment. Methods The source positioning detection device was made of hd camera,EBT3 disposable film and steel rule,collecting source in each resident point for video images and film. Accurate measurement of radioactive source positioning and timer accuracy, including the timing absolute error and linear error through analysis of image sampling rate. After the film grayscale distribution analysis,comparison between film gray peak position and the measurement of resident point geometry,got the stay point source physics and radiation center deviation. Results Radioactive source physics and radiation center deviation was (-0.33± 0. 10) mm;For all default dwell time,timer average absolute deviation was (0.22±0. 02) s,linear fitting result was y=x-0. 226,R2=1,timing linear error was-0. 01％ Conclusions established detection means through the video images and film exposure quantitative analysis for accurately determination of source positioning,dwell time and source radiation center precision. After experimental testing the machine precision satisfied the requirement of clinical use.
ABSTRACT
Diversos investigadores han intentado explicar desde inicios de la psicología, la experiencia temporal y su influencia en las cogniciones, emociones y comportamientos. Tratándose de una de las dimensiones más complejas e influyentes de la psique, ha sido abordado desde diferentes concepciones y sin contar con referentes comunes. Este artículo intenta contribuir a la sistematización de la psicología del tiempo ampliando un modelo de cuatro niveles, profundizando en la percepción del tiempo vital o tiempo III. Se han seleccionado trabajos relevantes en la historia de la psicología o con cierto índice de citación. Se ofrece un modelo explicativo del Tiempo III, que incorpora discusión y debate y pretende integrar diversos modelos existentes en la literatura.
Pesquisadores têm tentado explicar, desde o início da psicologia, a experiência temporal das pessoas e sua influência nas cognições, emoções e comportamentos. Trata-se de uma das dimensões mais complexas e influentes da psique, que tem sido abordada a partir de concepções diferentes e sem uma estrutura consensual. Este artigo tem o objetivo de contribuir na sistematização da psicologia do tempo, ampliando um modelo de quatro níveis, aprofundando na percepção do tempo vital ou tempo III. Trabalhos incluídos foram selecionados segundo a sua importância na historia da psicologia ou índice de citação. Sugere-se um modelo explicativo do Tempo III, que inclui discussão e debate e visa integrar os diferentes modelos existentes na literatura.
Since the beginning of psychology researchers have tried to explain the subjective experience of time on cognitions, emotions and behavior. As it is one of the most complex and influential dimensions of the mind, it has been approached from different conceptions without a common consensual framework. This article attempts to contribute to the systematization of the psychology of time expanding a fourfold model, which emphasizes life-time perception or Time III. Publications were selected that were either relevant in the history of psychology or had a good citation index. An explanatory model of Time III is proposed that incorporates discussion and debate and which intends to integrate various existing models encountered in the literature.
ABSTRACT
The purpose of this study was to explore the risk and pattern of injury which can happen to first time skier and snowboarder. From December 2006 to March 2008, questionnaires were provided to 7,786 patients injured from skiing or snowboarding and hospitalized. First time and experienced groups were distinguished through questionnaire and accidental reports. The differences in incidence, cause of injury, affected body region, type of injury, and severity of injury were compared between the two groups. Falling or slip down was the most common cause of injury in first timers, while collision with person was most common in experienced. Injured sites were similar in both ski and snowboard with arm and wrist as the most frequent injured body region. Sprain and contusion were the most common injury type for both groups. However, the incidence of ligament injury was higher in the first time skiers and concussion and dislocation in the first time snowboarders compared to the experienced. In conclusion, beginners in skiing and snowboarding happened to show different cause and features of injury compared to the experienced. Therefore beginners need effective programs differed from the ones of experienced, such as mentioning risks of skiing and snowboarding and reserving a porting of slopes to the beginners. Moreover, It is necessary to develop and effectively use protective gear in order to secure elbow joint and wrist eminence.

Since the year 2006,I have posted evidences and papers on magazine,webs,and conference.(Ⅰ)Those posts and papers discuss relationship among origin of EEGs,information processing in brain,and blood circulation.(Ⅱ)Those posts and papers suggest that blood circulation plays the role of basic timer when brain processing information;Suggest one possible molecular mechanism of this'olood cycle timer'.In the molecular mechanism,H+,O2,working mechanism of microcirculation system,H+seats of NMDA receptor are key factors.(Ⅲ)Those posts and papers suggest that the sense of'time passes'is the sense of'press'that comes of blood flowing in brain.The sense of'a physical continuous process'is constituted by two senses:(i)Sense of'press'(ii)Sense come from'a sequence of active metadata'.This paper is a review of those evidences and papers.Section 1 gives a description of the model.Section 2～5 give the evidences supporting the model,and clarify some problems.Section 6～8 use the model to explain some phenomena of neuroscience(e.g.Origin of alpha wave,EEGs from kinds of sleep phases,etc.).

ABSTRACT
The Psychopathology of schizophrenia is composed of many heterogeneous symptom complex, and multifaceted approaches have been done on this subject. It is so simplified a method that the complex symptoms of schizophrenia are classified into only positive and negative symptoms. Preceded studies of other researchers said cognitive deficit of the schizophrenics played important roles in the symptom formation. The purpose of this study is the evaluation of the relationship between the symptoms of schizophrenia and the memory function and low level of cognitive function. In this study, 30 subacute and chronic schizophrenic patients were included. PANSS(Positive and Negative Symptom Scale) was applied to evaluate the clinical symptoms in each subject. The memory function and low level cognitive function were evaluated using WMS-R(Wechsler Memory Scale-revised version) and Decision-reaction timer. The results showed negative correlations between cognitive factor of PANSS(5 factor model) and delayed recall of WMS-R. These results suggest the possibility that symptom evaluation using PANSS can be a preliminary estimation of cognitive function in schizophrenia.
