概要:
Departmental Bulletin Paper<br />In the wake of Covid-19 pandemic, youth in our country have been using the Internet for
…
extended periods of time. This paper analyzes the relationship between prolonged use and youth fatigue based on data from a cross-sectional survey we conducted between 2021 and 2022. It is known that Internet use for entertainment purposes, such as playing online games and watching videos, is becoming longer, but we would like to call attention to the fact that prolonged use for learning is also fatiguing in its own way. In this paper, we review the situation of schoolchildren’s Internet use as inferred from our survey, analyze the relationship between their health status and prolonged Internet use as revealed by the survey through cross tabulation, and discuss the relationship between Internet use for learning purposes and schoolchildren’s health status through multiple regression analysis.

概要:
Departmental Bulletin Paper<br />In 2021-22, we conducted a large-scale survey of elementary, junior high, and high school students to determine their Internet use and perceived health risks. This large-scale survey received 27,632 valid
…
responses. Based on the aggregate results, this paper attempts to clarify what kind of health risks youths are exposed to due to unhealthy Internet use in Japan. Health hazards include Internet addiction. Prolonged use of the Internet risks causing Internet addiction, and this was observed in all grades, from elementary to high school. Online-game disorder was said to be more common among boys, but in our study, a higher percentage of girls were found to be using the games in a dangerous manner.

…
pecially after a survey result of the Ministry of Health, Labor and Welfare survey team reported in 2013. This paper inquires how much schoolchildren are getting into the Internet addiction on surveys we executed in Maebashi City during these three years (2015 – 2017) including a longitudinal panel survey. The result tells us 4.5-7.9 % of elementary school children and 6.2-7.6% of junior-high school students belong to the high risk group. It also shows that once you fall into addiction, it is appropriately difficult to get out of such condition. We investigated also the influence of the parental control to the Internet addiction among pupils through asking the domestic rules and found that those rules could not prevent the overuse of the Internet of schoolchildren.

ttempts to identify the rate of the high-risk group of this “disease”among schoolchildren, to find out the distribution of them and what kind of net servicesthey incline to use on a survey we executed in primary and junior-high schools in Maebashi city, Gunma prefecture, Japan.\nThe result tells us that 7.9% of 5-6 grade primary schoolchildren and 6.8% of junior-high schoolchildren are regarded as belonging to the high risk group. According to our regression analysis, movie sites are the most influential among several online services for the “addiction score”we set on our questionnaire.We also find out the adaptationto schoollife is important for the score.

Departmental Bulletin Paper<br />The Internet addiction among schoolchildren has been regarded as one of the most seriou
…
s social problems. Not a few researchers point out that it is important to prevent students from falling into the addiction because it is very difficult to recover from this “disease.” This paper attempts to find out risk factors for this disease on a survey we executed in primary and junior high schools in Maebashi city, Gunma prefecture, Japan. The result tells us that 8.3% of 5-6 grade primary schoolchildren and 9.1% of junior-high schoolchildren are regarded as belonging to high risk groups. LINE, online games and movie sites are remarkably popular among the risk groups. They also incline to answer to our questionnaire that they feel the learning at school as difficult, uneasy with their own family, and reluctant to attend schools.

for\nseveral years in Japan. Although the ‘Act on Development of an Environment That Provides\nSafe and Secure Internet Use for Young People’was executed in 2009,not a few media reported\nthat there are many guardians who let their children use the mobile Internet without filtering\nsettings. This paper attempts to investigate the reason why they underestimate the risk of the\nmobile Internet in spite of numerous opportunities for them to know the risk by the information\ngiven by teachers, TV programs, or other media.

概要:
application/pdf<br />Departmental Bulletin Paper<br />The problem of the Internet use of schoolchildren is not a new one. It has been constructed\nas e'a social problem'"for these ten years. The coming of the Internet, above all, that
…
of the\nmobile Internet from mobile phones has changed the channels of the information flow and given\ntremendous influences upon the structures of our daily life in various fields. The situation that\nchildren are exposed to every kind of haumful and dangerous information which had been blocked\nout by the gatekeepers like their parents or teachers is quite a new experience we have to be\nconfronted with.\n This paper wants to investigate how teenagers in Guma prefecture use the mobile Internet\nand how the problems we mentioned above embody themselves, based on the survey which we\nexecuted on 2008-2010. We find out the fact that the parents fail to control their children's use\nof the Internet and that schoolchildren are exposed to latent dangers in their daily lives. It is\nnecessary to inquire how to build a desirable and feasible infoumation enviroument for teenagers\nand their parents.
