MORIGUCHI Yukako,OISHI Naoya,MURAI Toshiya,FUKUI Hiroki,FUKUYAMA Hidenao 아시아아동지원학회 2011 아시아아동지원연구 Vol.2 No.-

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.

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.

A Study of the Trend in Research Themes and Contents among Students Aiming to Become School Nurse Teachers (SNTs)

MORIGUCHI Yukako 아시아아동지원학회 2012 아시아아동지원연구 Vol.3 No.-

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 ,).

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.

THE EFFECTS OF BACKGROUND COLORS ON CONSUMERS’ HAPTIC EVALUATIONS AND PRODUCT PREFERENCES

Mayuko Nishii,Takeshi Moriguchi 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

Introduction Can the background colors of products on an online shopping site affect consumers’ haptic perceptions and evaluations? When shopping online, consumers cannot obtain a product’s haptic information by touching it directly and usually rely on visual information such as the product’s image and description. Nevertheless, consumers sometimes use haptic information to judge whether to purchase a product and marketers aim to engage consumers’ haptic preferences. Currently, researchers in the field of sensory-marketing research are interested in the interaction of multiple senses. Although previous research has demonstrated the interaction between visuals and haptic perception (e.g. Xu & Labroo, 2014), there is still considerable opportunity for further research on consumers’ haptic perception of products they cannot touch directly, such as through online shopping. In this study, we focus on how the background colors of product images affect consumer’s haptic perceptions and evaluations of the products. Theoretical Background Krishna & Morrin (2008) indicate that the interaction among plural senses is caused by perceptual transfer. When an individual perceives a sense, it is associated with previous experiences with other senses, which may cause perceptual transfer (Piqueras-Fiszman & Spence, 2015). For instance, Harrar, Piqueras-Fiszman, & Spence (2011) found that the color of the bowl affected consumers’ perceptions of taste when eating popcorn. In this study, when consumers ate popcorn in a red bowl, they associated the color with mature fruit and evaluated the popcorn as sweeter. Consumers who ate popcorn from a blue bowl evaluated the popcorn saltier because they associated the color with the sea. Based on these results, we predict that the background colors of products will affect consumers’ haptic perceptions and product preferences. Babin, Hardesty, & Suter (2013) show that red and orange induce the perception of warmth. Thus, an orange background color causes consumers to perceive products as warmer. Zwebner, Lee, & Goldenberg (2014) demonstrate the influence of physical warmth on consumers’ behavior and they focus on the anthropomorphic characteristics of products. They mention that consumers tend to perceive inanimate products as anthropomorphized so when they percept warmth to products, they feel emotional warmth and it induces their intention to purchase them. From their findings, we predict that the effect of warm background colors is restricted to anthropomorphized products. Additionally, warmth is strongly associated with softness (Tai, Zheng, & Narayanan, 2011). Hence, we also predict that warm background color might affect consumers’ perception of softness of the products. H1: The color orange is perceived as warmer than white (control). H2a:When the background color is orange (vs. white), anthropomorphized products are evaluated with more familiarity. H2b: When the background color is orange (vs. white), anthropomorphized products are evaluated more favorably. H2c: When the background color is orange (vs. white), there is greater intention to purchase anthropomorphized products. H3a:When the background color is orange (vs. white), anthropomorphized products are perceived as warmer. H3b: When the background color is orange (vs. white), anthropomorphized products are perceived as softer. H4: The perception of the warmth of products affects the perception of softness of products. H5: The influence of “H2a” mediates the perception of warmth of products. Methods We conducted two studies to research the hypotheses above. Warm and soft inanimate products are anthropomorphized (Horowits & Bekoff, 2007), and we researched this hypothesis by comparing warm and soft products with cold and hard products in study1. For the purpose of identifying warm and soft products (anthropomorphized products) as well as cold and hard products (non-anthropomorphized products), we conducted a pretest. For the study1 pretest, we chose a teddy bear, futon, and scarf as anthropomorphized products and a garbage can, ice pop, and glass as non-anthropomorphized products. In study2, we used hand watches, which are considered cold and hard. However, a watch indicating 10:10 is recognized as a smiling human (Labroo, Dhar, & Schwarz, 2008). Hence, we compared watches set to 10:10 and 12:00. For study1 and study2, we conduct a 2 (orange vs. white) × 2 (anthropomorphized products vs. non-anthropomorphized products) between-subject test on the participants. Participants answered a questionnaire on a website. They evaluated the color and products on a 7-point Likert scale. For both study1 and study2, we recruited participants via the Internet. They received a point worth 3 JPY (approximately 0.03 USD) for participating in the study. Results Study1 We used a t-test to compare the averages of warmth to the background colors. It showed a significant difference between Group orange and white (t=32.329, df=916.938, p< .001). For H2a to H3b, we conducted the two-way ANOVA of 2 (background color: orange, white)×2(anthropomorphic characteristics of products: anthropomorphized, non-anthropomorphized). The results showed no interactions. Hence, we used t-tests (See Table1). The results supported H2a to H3b. In addition, we conducted a path analysis on the influence of the perception of products’ warmth toward the perception of products’ softness. The influence was significantly positive (β=0.776, p<.001). In comparison, the path from the background colors to the perception of products’ softness was not significant (p= .142). Hence, H4 was supported. Study2 We used a t-test to compare the averages of warmth to the background colors. It showed a significantly positive difference between Groups orange and white (t=22.206, df=323.539, p< .001). Therefore, H1 was supported again. Aside from the above analysis, the results supported H2a to H3b (See Table2). Furthermore, to test H4, we conducted a path analysis on the influence of the perception of products’ warmth towards the perception of products’ softness. Results showed that the influence was significantly different (β=0.823, p<.001). In comparison, the path from the background colors to the perception of products’ softness was not significant (p= .142). Thus, H4 was supported again. Moreover, to test H5, we ran the mediation model by using the PROCESS macro (Model 4, Hayes, 2013). For anthropomorphized products, bootstrapping tests with 2,000 bootstrapped samples revealed that the effect of background colors on familiarity was mediated by the perception of the warmth of the products(a×b=0.09, 95%CI=0.058 to 0.478 excluded 0). The direct effect c’ (0.15) is significant (p= .045), although c (0.06) is not significant (p= .385). On the other hand, for non-anthropomorphized products, the regression analysis revealed that the direct effect c’ (-0.03) is not significant (p=0.711). Hence, H5 was supported. Discussion and Conclusion We demonstrated that warm background colors affect the perception of products’ warmth and softness and increase consumers’ intention to purchase products. We also found that the effect of warm background colors is restricted to anthropomorphized products. This research showed that the effect of warm background colors on the familiarity of anthropomorphized products was mediated by the perception of the products’ warmth. Based on these results, we also demonstrated that the perception of products’ warmth influenced the perception of their softness. Our findings might help to apply Zwebner et al. (2014)’s findings regarding online shopping sites where consumers cannot touch products directly and marketers cannot control consumers’ room temperature.
