Psychiatric nurses’ observation techniques

The purpose of this study was to clarify characteristics of psychiatric nurses’ observation techniques for psychopathological symptoms. The subjects were 21 psychiatric nurses and 20 nursing students who had finished their practicum in psychiatric nursing. Using a non-contact eye-tracking analysis system, we compared quantitatively their radial motion while they were observing psychopathological symptoms of a schizophrenia simulation patient. The radial motion of them was recorded while they were observing a video of a simulated patient presenting psychopathological symptoms, and the recording was analyzed by the eye-tracking system. The investigator set the important observation areas and determined the sum of the fixation time and the number of fixations in the areas. Differences between psychiatric nurses and nursing students were tested using the Mann-Whitney U-test. The results revealed a significant difference in observation of the upper limbs area with a median of 7147.90 msec for nurses group and a median of 2447.54 msec for students group (U = 98.00, p = 0.01). The finding suggests that nurses tend to pay more attention to patient’s upper limbs to be cautious about possible violence and to find agitation caused by psychopathological symptoms, extrapyramidal adverse effects, and scars caused by self-mutilation

Radially Anisotropic Ring/Arc-Shaped Rare-Earth Bonded Magnets Using a Self-Organization Technique

We developed a new technique using self-organization of binder that enabled the alignment of a molecular chain. By using this technique, we controlled the flexibility of Nd-Fe-B-based rigid sheet magnets, transformed them into various shapes, and succeeded in preparing radially anisotropic ringor arc-shaped magnets. Optimizations of the consolidation process of the self-organization binder under a transverse alignment field and the transformation process into various specific shapes realized radially anisotropic magnets with 160 kJ/m 3 in (BH)max

A Study on Relationship between Psychological Well-being and Menstrual-Associated Symptoms in Female University Students

Female-specific menstrual-associated symptoms are regarded as a factor to lower psychological well-being. The purpose of the current study was to clarify the relationship between psychologocal well-being and menstrual-associated symptoms. We conducted an anonymous survey using self-report questionnaires, in which the MOS 36-Item Short-Form Health Survey version1.2 （SF-36） and the Menstrual Distress Questionnaire （MDQ） were administered to 382 female university students in order to evaluate health-related quality of life and menstrual-associated symptoms respectively. Data from 311 subjects were analyzed to investigate the relationship between the two scales before, during and after menstruation and in strong and weak menstrual-associated symptoms groups. There were significant negative correlations between the SF-36 subscale ‘vitality’ and the MDQ subscale ‘negative affect’ before and during menstruation. In the strong menstrual-associated symptoms group, significant negative correlations were found between subscales of the SF-36 and the MDQ before, during and after menstruation, suggesting that psychological symptoms of menstrual-associated symptoms might influence their physical and psychological quality of life. We concludes that to examine coping methods in order to reduce psychological symptoms and to provide individualized education are necessary

QOL in schizophrenia inpatients

Objective : The purpose of this study was to clarify the relationship between quality of life (QOL) and clinical factors in inpatients with schizophrenia. Methods : Subjects were 50 hospitalized patients with schizophrenia. Their mean age was 56.48 (Standard Deviation = 11.93) years. Japanese version of the schizophrenia Quality of Life Scale (JSQLS) and Subjective Well-being under Neuroleptic drug Treatment Short form, Japanese version (SWNS-J) were used to assess subjective QOL, and Mini Mental State Examination-Japanese was used to evaluate cognitive function. Japanese version of the Calgary Depression Scale for Schizophrenia (JCDSS), Brief Psychiatric Rating Scale, and Drug-Induced Extrapyramidal Symptoms Scale were used to assess depression severity, psychotic symptoms, and drug-induced extrapyramidal symptoms, respectively. Stepwise regression analyses were conducted to find factors influencing JSQLS and SWNS-J. Results : JCDSS was a predictor of two scales of JSQLS, and JCDSS also predicted SWNS-J Total and it’s two subscales. However, other clinical factors were not related to JSQLS and SWNS-J. Conclusion : The results indicate that treating depressive symptoms may lead to improvement of subjective QOL in inpatients with schizophrenia

Path Loss Prediction Model for a Sloped Area in Microcell Based on Scale Model and Real Environment Measurements

The forests in Japan occupy 70% of the country, and there are many mountains and hills in Japan. As cities and residential areas have expanded the living space for people has spread to such hilly or sloped areas. Mobile communication systems are already a vital infrastructure to daily life, so covering these sloped areas is important in terms of service provisioning. It is necessary to predict propagation losses over the sloped areas for radio link design.The 1st IEEE Asia Pacific Conference on Wireless and Mobile 2014 (APWiMob 2014), Aug. 28-30, 2014, Grand Inna Kuta Hotel, Bali, Indonesi

HCV Virus and Lymphoid Neoplasms

Hepatitis C virus (HCV) is one of the viruses known to cause hepatic cancer. HCV is also believed to be involved in malignant lymphoma. In this paper, we investigated characteristics of malignant lymphoma cases that were anti-HCV antibody (HCV-Ab) positive. We were able to perform pathological examinations on 13 out of 14 HCV-positive cases. Of these, lymphoid tissues of 10 stained positive for HCV-Ab. There was no significant correlation between the degree of HCV staining and the rate of recurrence or resistance to treatment. However, there did appear to be a consistent decrease in the amount of HCV-RNA between pre- and posttreatment among HCV-Ab-positive cases; that is, treatment-resistant cases that exhibited resistance from the first treatment and recurrent cases more frequently had a higher HCV level at treatment termination compared to the pretreatment level. This suggests that the HCV virus either accelerates oncogenesis by direct interaction with B cells or indirectly affects lymphoma prognosis

Rituximab Administration and Reactivation of HBV

Rituximab is a drug used for the treatment of B-cell non-Hodgkin's lymphoma, and its range of use has expanded to the treatment of collagen diseases such as idiopathic thrombocytopenic purpura and rheumatoid arthritis. One serious complication of rituximab use is the reactivation of dormant hepatitis B virus, and prevention of this phenomenon has become an urgent issue. This paper provides a general outline of the problem through an analysis of patient cases that we and other groups have experienced to date

Reduction in Flux Loss of an Nd-Fe-B Bonded Ring Magnet for an SPM Motor

We have previously proposed a simulation method of an initial flux loss in permanent magnets using finite element method, and confirmed that predicted flux loss of an Nd-Fe-B boned ring magnet showed good agreement with measured flux loss. In this paper, we applied our proposed method to an Nd-Fe-B boned ring magnet in an SPM motor. We modeled a rotor composed of an Nd-Fe-B bonded ring magnet and a soft magnetic core made from silicon steels, and carried out the simulations for magnetizing process and prediction process of the flux loss. From the simulation results, we found that the inner side of the ring magnet has large flux loss. In order to reduce in flux loss, we enhanced the coercivity in the inner side of the ring magnet by partial replacement with another bonded magnet with high coercivity. Consequently, we found that the ring magnet with locally enhanced coercivity is effective to reduce in the flux loss
