The primary objective of graduate research conducted in the final year of training curriculums for school nurse teachers (SNTs) is “to enhance learning outcomes by selecting an interesting topic in a specialized area and studying it in a self-directed manner" ‘ It is expected that students develop an ability to implement a task with enhanced awareness and motivation in their future workplaces by conducting graduate r esearch as a summary of their learni ng experiences at the university This study analyzed research areas , motivations, subjects , and methods , involving a11 students (29) the author supervised over the past 4 years (school years 2006/07 to 2009/10). As a result, it was demonstrated that most students aiming to become SNTs were mainly int erested in topics related to health , society, and education. The majority of research methods were literature and ques ti onnaire studies. Primary motivations for research included: training outside the university; classes; and experiences of their own , friends , and acquaintances. Further, th ere was a tendency for research themes and key issues to include new topics peculiar to each year ; therefore , it may be necessary for supervisors to actively deepen th eir knowledge of related areas , such as h ealth-related issues. It may also be necessary to exa mine appropriate methods t 。 guide students who change th eir research themes afterward, in addition to efficient supervision (scheduling, timing of guidance, etc ,).

The risk of committing a crime, including drug offenses, increases in adolescents. Along with the increase in drug offenses, the majority of those in medical reformatories for juvenile offenders are youth8 with mental illness, rather than those with physical illness. A decline in executive function is one of the commonly reported neuropsychological traits of substance dependents; however. most studies examine substance dependence in adults. and there have been only a small number of studies on adolescent substance abuse. limiting the type of substance to marijuana and alcohol. ln this study. the executive function, personality. and behavior in male youths of a medical juvenile reformatory, whose rate of substance abuse offenders is higher than that in general. were investigated. The results demonstrated higher degrees of impulsivity, verbal aggression, and apathy in youths with substance dependence than in those with an equivalent lQ and criminal history without experience of illegal drug use. A decline in the Wisconsin Card Sorting Test results Was also observed in the former. On the other hand, per80nality and behavioural traits, such as enhanced apathy, were observed in youth8 with experience of illegal drug use without having a diagnosis of substance dependence. These results suggest that it is important for health care professionals to provide medical treatment and support while fully understanding the personality and behavioural tendencies, peculiar to adolescent substance abuse, such as high degree8 of impulsivity. verbal aggression, and apathy.
An Instrumented Workstation to Evaluate Weight-Bearing Distribution in the Sitting Posture
Moriguchi, Cristiane S.,Sato, Tatiana O.,Coury, Helenice J.C.G. Occupational Safety and Health Research Institute 2019 Safety and health at work Vol.10 No.3
Background: Sitting posture may be related to risk factors, including inadequate weight-bearing support, particularly when maintained for long periods. Considering that body weight is loaded in a closed support system composed of the seat, backrest, floor and working surface, the aims of the present study were to describe the development of an ergonomic sitting workstation to continuously record weight-bearing at the seat, chair, backrest, work surface, and floor and to test its measurement properties: reproducibility, criterion-related validity, and sensitivity. Methods: Rigid bodies (1 to 30 kg) and participant weights were recorded to evaluate the workstation measurement properties. Results: Rigid body tests showed variation values less than 0.050 kg on reproducibility test and errors below 5% of measured value on criterion validity tests. Participant tests showed no statistically significant differences between repeated measures ($p{\geq}0.40$), errors were less than 2% of participant weights an sensitivity presented statistically significant changes (p = 0.007). Conclusion: The sitting workstation proposed showed to be reliable, valid and sensitive for use in future ergonomic studies to evaluate the sitting posture.

Neutron-production double-differential cross sections for 290 MeV/u carbon-ion incidence on carbon target were measured with NE213 liquid organic scintillators by time-of-flight technique. NE213 liquid organic scintillators 12.7 cm in diameter and 12.7 cm thick were placed in the directions of 15˚, 30˚, 45˚, 60˚, 75˚, and 90˚. The typical flight path length was 4.0 m. In order to reduce neutrons from the beam dump, an iron and a concrete shield was placed between the detectors and the beam dump. For measurement of background, a shadow bar was set between the target and each detector. Neutron detection efficiencies were obtained by calculations with a Monte Carlo simulation code SCINFUL-QMD. The cross sections were obtained for neutron energy above 2.8 MeV. The experimental results were compared with the calculation data of the PHITS code.

Our goal was to create colonization and invasion risk maps for the Argentine ant, Linepithema humile, based on occurrence data in Japan, by combining colonization- and invasion-related variables and spatial filters that alleviate spatial autocorrelation. With these data, we will be better able to implement surveillance and control programs. Species distribution models were generated, using the maximum entropy approach, from presence-only data collected from 12 locations. Colonization-related variables (e.g., temperature, precipitation) and invasionrelated variables (e.g., urban area, distance from ports) were used as environmental variables and spatial filters that alleviate spatial autocorrelation were included at the same time. The high invasion risk area was restricted to coastal areas, whereas high colonization risk applied to a broader area. Elevation, minimum temperature, and flowaccumulationwere themost effective variables for predicting colonization risk,whereas urban area, elevation, and the port distance index were the most effective variables for predicting invasion risk. The invasion risk map had a higher level of accuracy than the colonization risk map. We identified those areas with a high risk of invasion in the early stages and strong propagule pressure with a model using both invasion-related variables and colonization-related variables to accurately estimate the initial invasion distributions. We found that high colonization risk areas were concentrated in the Okinawa and Ogasawara Islands; ecosystems with highly endemic ant species that are likely to have a high sensitivity to L. humile introduction. Our data will aid in strengthening both domestic and international quarantine systems to prevent such introductions.

Neutron-Production Double-Differential Cross Sections from Heavy-Ion Interactions
D. Satoh,D. Moriguchi,T. Kajimoto,Y. Koba,Y. Nakamura,N. Shigyo,M. Ueyama,Y. Uozumi,M. Yoshioka,N. Matsufuji,M. Takada,T. Sanami 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
The existing data of neutron-production double-differential cross sections on C, Cu, and Pb targets bombarded with heavy-ions from He to Xe at 230 - 600 MeV/nucleon were revised by using a new set on neutron-detection efficiency values of an NE213-type liquid organic scintillator calculated with SCINFUL-QMD. The revised data were compared with the experimental data obtained by our new measurements, and the predictions of the Monte-Carlo particle transport codes, PHITS, FLUKA, MCNPX, and Geant4. While the revised and new experimental data showed good agreement, the Monte-Carlo codes failed to reproduce the high-energy peaks in the forward angular region.
