In this research, a cohort of two children, aged 7-8 years, was selected to participate in a specialized three-week training program aimed at enhancing their working memory. The program consisted of three sessions, each lasting approximately 30 minutes. The primary goal was to investigate the impact and developmental trajectory of working memory in school-aged children. Working memory plays a significant role in young children's learning and daily activities. To address the needs of this demographic, products should offer both educational and enjoyable activities that engage working memory. Digital educational tools, known for their flexibility, are suitable for both older individuals and young children. By updating software or modifying content, these tools can be effectively repurposed for young learners without extensive hardware changes, making them both cost-effective and practical. For example, memory training games initially designed for older adults can be adapted for young children by altering images, music, or storylines. Furthermore, incorporating elements familiar to children, like animals, toys, or fairy tales, can increase their engagement in these activities. Historically, working memory capabilities have been assessed predominantly through traditional intelligence tests. However, recent research questions the adequacy of these behavioral measures in accurately detecting changes in working memory. To bridge this gap, the current study utilized electroencephalography (EEG) as a more sophisticated and precise tool for monitoring potential changes in working memory after the training. The research findings were revealing. Participants showed marked improvement in their performance on n-back tasks, a standard measure for evaluating working memory. This improvement post-training strongly supports the effectiveness of the training program. The results indicate that such targeted and structured training programs can significantly enhance the working memory abilities of children in this age group, providing promising implications for educational strategies and cognitive development interventions.

Background: This study aimed to investigate whether there is a difference in organizational member attitudes by workplace environment and workplace types in dental hygienists working at dental health centers. Methods: A face-to-face survey or online survey was administered to dental hygienists working at dental health centers, and a total of 95 subjects were included. The survey includes 13 items to ask factors affecting employee's job satisfaction. Also, some questions were included to assess perception of organizational member attitude: five about organizational citizenship behavior, two about innovative behavior, and four about organizational commitment. Results: Dental hygienists working at dental clinics were more satisfied with their incomes and numbers of working days, while those from dental university hospitals and general hospitals were more satisfied with education support. In addition, hygienists working at dental hospitals were more satisfied with job autonomy, individual work capability, safe working environment, personal relation, potential for personal development, and positive labor-management relations, compared to those working at general and university hospitals (p<0.05). Among the items about perception of organizational member attitudes, the scores of items about organizational citizenship behaviors were higher, whereas the scores of items about innovative behaviors were relatively lower. Individuals working at dental hospitals than those working at general and university hospitals, chiefs and team and department leaders than team members, and those with increased satisfaction with current workplace had more positive perception of organizational member attitudes. Conclusion: For dental hygienists to have positive attitudes as organizational members, working environment should be improved, and executives of dental healthcare centers should pay attention to improving job satisfaction of organizational members. Moreover, since dental hygienists need to improve their perception of innovative behaviors and citizenship behaviors to strengthen specialty of dental hygienists in a changing dental healthcare, relevant training should be addressed in refresher courses or school programs.

This study aims at determining what affects lighting environment of a kitchen in a Japanese restaurant in a hotel and at analyzing. cooks' perception during cooking and appropriate lighting they consider to be important in each working area. For this purpose, 196 cooks working in Japanese restaurants in first-class hotels participated in a survey. After analyzing the results, cooks attach importance to illumination during cooking, and the more inappropriate luminosity is in each working area, the lower appropriateness of luminosity recognized by cooks is. And there is strong correlation between lighting environment items and illumination in each working area. The results suggest that cooks working in a Japanese restaurant in a hotel should be provided with good lighting environment appropriate for each working area. On this ground, it is expected that cooks will see their health and productivity improving.

This study examines difference in expenditure patterns between working-wife families and nonworking-wife families. The data used in the study is 4,506 husband-wife families take National Survey of family Income and Expenditure in 1996. Of the sample, 42.3% are working-wife families. Consumption expenditure patterns are analyzed in two ways. One is the budget share of each given expenditure and the other is elasticity of those expenditure. The main results of this study are as follows: First, there are the differences between working-wife families and nonworking-wife families in the budget share of each given expenditure. In the budget shares of each given expenditure, nonworking-wife families share more than working wife families for food and medicine. And working-wife families allocated more on public transportation than their counterparts. Second, there are also differences between working-wife families and nonworking-wife families in income elasticities.

The purpose of this study was to present the thermal characteristics of the working uniform exposed to the radiation heat. The effect of exposure time and exposure distance on the changes and the relationship between physical properties were investigated experimentally. Regardless of the kind of working uniform, the surface temperature of the working uniform with exposed time sharply increases as exposed distance is more close and the reaching time of steady state is shorter. The surface temperature of working uniform exponentially decreases as exposed distance become more distant. For the safety of the working man, it is necessary that he work far away at a fixed standard distance from the radiant heat source.

Purpose: This present study has been conducted on female workers' shorter working hours in order to look into their fatigue level and the correlation between fatigue and working hours. Method: We surveyed 237 respondents using a questionnaire from June 1st to June 20th, 2005. Results: The means of total fatigue complaint was 3.45. The fatigue level was significantly higher in the lower age group, unmarried group, manager group and shorter working duration group. And the fatigue level was significantly correlated to working hours and work intensity. In the results of stepwise multiple regression, factors affecting the fatigue level were the change of work intensity, age, regular diet habit, working hours and the type of occupation. Conclusion: It is necessary to prepare the health promotion programs, which can reduce female workers' fatigue level and relieve the intensity of their works.

The organic Rankine Cycle (ORC) uses a kind of refrigerant as a working fluid that evaporates at relatively low temperature, as the Rankine Cycle uses superheated steam as the working fluid. A small scale ORC test bench was installed, and two different working fluids (R245fa and R134a) were injected into the test bench. The test bench was in operation with the two different working fluids under the same conditions. The effects against the system performance from the different working fluids were analysed, and root causes were identified. Other factors reflecting the power generation efficiency were also found. A conclusion was drawn, that R245fa makes the system perform better, than R134a.

The differences of coping behaviors of professional and non-professional working mothers were assessed using data(n=704) from the working mothers with children under age 18. Professional working mothers' individual characters family and occupational conditions are more suitable than non-professionals for the coping behaviors. And such individual and situational aspects may relate to the differences of coping behaviors of he two groups. In general professional working mothers use coping behaviors more except the 'role reducation' and 'taking the support of fiends & neighbor' On the other hand the conservativeness and passive attitude in role strain coping is the same aspect of the two groups. Finally the relation of individual character family and occupational condition of working mothers to their coping behavios are slightly different in this two working mothers groups.
