러시아는 1960년대부터 교육의 차등화에 관련된 다양한 논의가 진행되었고, 1980년대부터 수학교육학 영역에서 차등화된 교육에 관련된 다양한 연구가 본격적으로 이루어졌다. 본 연구에서는 1990년대에서 1995년까지 러시아의 수학교육의 차등화에 관련된 연구들을 분석하여, 수학교육 차등화의 개념, 핵심 변인들을 규명하고, 수학교실에서 차등화된 교육의 구현 방법을 고찰하였다.

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.

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.
