    It is considered that the psychological distance between the nurses and patients influences the care for patients. The purpose of this study was to clarify the characteristics of the concept of “the psychological distance between the nurses and patients from nurses’ point of view,” and to define this concept. After identifying 34 articles, an analysis was conducted using the Rodgers’ method of concept analysis. The analysis revealed the following characteristics of psychological distance between the nurses and patients from nurses’ point of view. The attributes were: the cognition of patients’ information, controlling emotions toward patients, awareness of their professional roles, nurses’ sense regarding degree of togetherness with patients, and the dynamic movement of the mind. The antecedents were: the physical exchanges, characteristics of nurses, and characteristics of patients. The consequences were: the emotions of patients and their family, trusting relationship between nurses and patients and their family, and nurses’ behaviors toward patients. The proposed definition of the concept was the nurses’ dynamic movement of the mind which obtained the sense of togetherness with patients, controlling their emotions, while being conscious of their professional role. It was suggested that the nurses could consciously reflect on the care for patients from the perspective of psychological distance.

    The purpose of this study was to investigate factors associated with the occurrence of potentially serious medical near-misses, incidents, and accidents. A self-administered questionnaire was completed by 328 nurses performing shift work at general hospital A in the Kanto region. 1165 shifts worked by these nurses in seven days were analyzed by comparing two groups, one with near-misses or incidents and one without near-misses or incidents during a shift of work. Five nurse related factors( gender, duties of the day, drowsiness, consecutive waking hours, and level of fatigue), two patient related factors( level of nursing care - A score and B score), and four environmental factors( working shifts of the day, patient-nurse ratio, hours of work, and break time) were found. There was a significant relationship between both near-misses and incidents and nurses who were awake continuously for 17 hours or more. There was no significant relationship existed in nearmisses or incidents and the presence or absence of naps. From these results, continuous waking was indicated as a risk factor of near-misses and incidents.

    To provide evidence for fall prevention in schizophrenia patients, we evaluated the characteristics of their postural sway by using a stabilograph and studied the factors explaining these characteristics. We measured the postural sway of 40 schizophrenia patients from the in- and out-patient departments of a psychiatric hospital. The average total trajectory length from the center of gravity when the patient’s eyes were open unchanged as compared to healthy controls. However, when their eyes were closed, it was 13 cm shorter than that of them( p<0.01). The average location of the center of gravity in patient’s shifted backward by an average of 3.0 cm when the patient’s eyes were opened and closed as compared to them( p<0.01). Multiple linear regression analysis with variables such as age, sex, outpatient status, disease duration, amount of anti-psychotic and anti-anxiety drugs, and levels of drug-induced extrapyramidal symptoms revealed that disease duration was significantly associated with a longer trajectory from the center of gravity. The center of gravity likely shifted backward with higher doses of anti-psychotics; however, these observations were noted only when the patient’s eyes were closed.

    Although the novel respiratory-gated PET imaging is a commercially available technique, no details of its accuracy and its optimal parameter have been reported. Therefore, the accuracy and optimal acquisition window size were evaluated using a dynamic motion phantom which can simulate breathing movements of the human body. A PET scan was performed using a moving NEMA/IEC body phantom with six hot spheres( diameter: 10 ─ 37 mm) by changing the acquisition window size as an index of the respiration phase. In the reconstructed PET images obtained from different window sizes, the image quality was improved when the window size was narrow. Especially, the improvement of image quality for the 10 mm sphere was significantly higher than that of the other hot spheres. However, the statistical noise contained in the acquisition PET data was increased when the window size was narrow. The optimal acquisition window size was 25% of one breathing cycle.

    Smoking and radon inhalation are the primary causes of lung cancer in many countries. The world average annual dose due to radon inhalation is 1.26 mSv y-1, which is more than half of the annual exposure dose from natural radiation sources, 2.40 mSv y-1. In this study, radon and thoron radioactivity concentrations( hereafter referred to simply as concentrations) measurements were carried out in the Tokyo Metropolitan University Arakawa Campus building using a pulse type ionization chamber and passive radon and thoron discriminative monitors. The respective average (±σ) radon concentrations (Bq m-3) for each day of the week from Sunday to Saturday were: 21 ± 7, 20 ± 7, 20 ± 8, 22 ± 6, 21 ± 7, 20 ± 6, 23 ± 7. On week days, the radon concentration peaked daily at 8:00 am with a value of 25 ± 6 Bq m-3, it decreased until 7:00 pm reaching a value of 17 ± 7 Bq m-3, and then, showed a rising trend to the next morning’s peak. Radon concentration tended to show a higher value and less fluctuation on weekends. No seasonal change was observed. No correlation was observed between radon concentration and thoron concentration. In Japan, the repor ted arithmetic average radon concentration indoors is 15.5 Bq m-3 and the arithmetic average concentration outdoors is 5.4 Bq m-3. The annual effective dose of radon by inhalation in Japan is 0.64 mSv y-1. The average radon concentration of reinforced concrete buildings tends to be higher, though a radon concentration survey in reinforced concrete buildings in Japan is lacking. Calculated annual average exposure dose in the campus reinforced concrete building was 0.15 mSv y-1. Annual average exposure dose considering an indoor environment other than the Arakawa Campus building was 0.42 mSv y-1.
