In this paper we analyze various russian studies related with differentiated mathematics education. Especially we work on the studies published in 1980-1995 years. As a result, we find that many studies are carried out with various view points in different directions, draw out essential variables, embodiment methods of differentiated mathematics education in Russia.

Purpose: This study aimed to analyze the research trends on the image of emergency medical technicians (EMTs) in studies published in Korean journals. Methods: Electronic databases were searched, including RISS, KMbase, and KCI. Eight studies from 21 references screened were included in the analysis. Results: The number of studies related to the image of EMTs is severely lacking. The research methods and participants are limited to questionnaire surveys and EMT students, respectively. In addition, most of the studies used modified tools developed for image measurement of other occupations. Conclusion: Image research for EMTs should include various methods and participants. Standardized measurement tool development and image-related research should be steadily conducted.

This study aims to investigate the antecedent of consumer personal preventive equipment purchase behaviour by extending the HBM model after the pandemic. Pandemic related studies have focused on the effect of perceived susceptibility and perceived severity on consumer preventive behaviour, little studies have investigated the antecedents of consumer perceived risk. This study filled the gaps in the previous studies. This study tested all proposed hypotheses among users who have purchase the self-preventive behaviour. In final 253 valid data were collected through online survey for statistics analysis. This study found that consumer's health consciousness significantly impacted consumer's perceived severity of COVID-19 and perceived risk. Perceived risk positively impacted consumer self-preventive equipment purchase intention. In contrast, perceived susceptibility did not significantly consumer perceived risk. Based on these results, the theoretical implication will be offered on the study of health-related studies and will be given insight for disease control center to effectively manage consumer self-preventive behaviour.

The purpose of this study was to provide the basis for establishing policies and recommendations to the legal system to ensure children's safety related to playground equipment and toys. The present legal system, including national inspections and safety requirements were reviewed both in Korea and other advanced countries. Several issues were found related to accident prevention and improvement of playground and toy safety in Korea. Recommendations were made for the development of educational safety programs for children, parents, teachers, consumers, industry, administrators, and policy makers.

According to recent empirical studies, there is a systematic pattern in temporal behaviors of asset returns, and that systematic pattern is related to the business cycle. I propose a model which captures this evidence. This is done by considering a state dependent preference structure where state dependency is related to the business cycle. In this setting, the three main puzzles(i.e., the volatility puzzle, the equity premium puzzle, mean reversion) are understood as interrelated behaviors.

This paper presents case studies on the oil related failures in automotive engines. In this study, engine oils play an important roles as a friction reducing matehals and should be supplied to a tribological machine elements sufficiently. The starvation or depletion of a lubricant may seriously produce the tribological failures on the rubbing parts of the engine.

The purpose of this study is to investigate consumption values of adolescent consumers and related variables. The data were collected from self administered questionnaire with 560 students attending 6 middle/5 high schools in Seoul. Sub dimensions of each consumption value were extracted through factor analysis. Differences were found on some sub dimensions of each consumption value according to demographic variables, consumer abilities and the level of mother's consumer socialization practice perceived by students.

The relation of parental sociability and parenting behaviors (such as warmth and control) to shyness in children was examined. The subjects were 280 fifth-and sixth-grade children (139 boys and 141 girls). The data were analyzed by multiple regressions. Results showed that (1) maternal sociability was related to shyness in children: the more sociable the mothers, the less shy their children, and (2) paternal and maternal warmth were related to shyness in children: the warmer the fathers and mothers, the less shy their children.

This study is to survey on the status of human resource training programs related to ubiquitous technologies and services of domestic universities. So, this study develop a classification system about human resource related to ubiquitous technologies and services. We propose the implications and plans which are based on the status of human resource training programs related to ubiquitous technologies and services. Human resources related to ubiquitous technology are classified by the flow of information in ubiquitous environment. And human resources related to ubiquitous service are classified by ubiquitous user view. This study can be used to find collaboration alternatives for breeding up ubiquitous human resources and referred to analyzing on the supply and demand of ubiquotous human resources.
