사교육비 지출이 청소년 자녀의 우울과 신체증상에 미치는 영향
이성림,김진숙,Lee, Seonglim,Kim, Jinsook 대한가정학회 2022 Human Ecology Research(HER) Vol.60 No.2
This study examined the effect of private educational expenditure on adolescent depression and somatic symptoms. The sample comprised 2,589 first-grade middle-school students who completed the 2018 Korea Children and Youth Panel Survey. Data were analyzed using ANOVA (the generalized linear model), multiple regression, and quantile regression analysis. The principal results were as follows. First, 15.15% of adolescents reported depression symptoms, and 15.57% reported somatic symptoms. Second, levels of depression were significantly different among classes with a different level of private educational expenditure. Third, depression level was significantly negatively associated with private educational expenditure, in that the higher the private educational expenditure, the lower the depression level. Fourth, the effect of private educational expenditure on adolescent depression was significant at the 70~90th quantile regression, suggesting that private educational expenditure was associated with a higher level of depression symptoms. The results indicate that private education was viewed as a consumption commodity rather than a complementary educational practice or investment in human capital. Private education as a commodity might induce the highly developed and costly private education market. In turn, there is an increased financial burden for education at one end of the social-economic continuum and depression caused by relative deprivation at the other end.

This study was performed to investigate anti-microbial activity of soybean extract against oral microbes, and to determine the minimum inhibition concentration (MIC) for microbes causing oral diseases. The soybean extract was prepared using ethyl acetate and it was treated with 16 types of oral microbes at a concentration of 5.00 mg/ml (0.5%). The MIC of soybean extract for three major microbes causing oral diseases was determined. The anti-microbial activity and MIC were measured using broth dilution method. Significant reduction of microbial activities of 9 types oral microbes when the soybean extract was added to the broth compared to the control (p<0.01). The extract showed higher anti-microbial activity against some anaerobic strains (P. gingivalis and P. intermieia). S. mutans, which causes dental caries, showed MIC at a concentration of 40 mg/ml for the soybean extract. P. gingivalis, which causes adult periodontal disease, showed MIC at a concentration of 20 mg/ml for the extract. C. albicans, which causes denture stomatitis and angular stomatitis, showed MIC at a concentration of 20 mg/ml for the extract. These results indicate that soybean extract showed anti-microbial effort against 9 types of oral microbes, and the anti-microbial effect of the extract against oral microbes was stronger against fungi than against bacteria. The anti-microbial mechanism of soybean extract against oral microbes should be investigated, and more research for clinical application is required at a level of actual intake.

본 연구는 성희롱 인식과 융합 요인을 파악하고자 전남지역 치위생과 학생들 418명을 조사하였다. 자료분석은 SPSS 22.0 프로그램을 이용하였다. 성희롱 인식 정도는 4.18점이었으며 성별(p=0.003), 학년(p=0.001), 성희롱 피해 경험(p=0.007)에서 유의한 차이가 있었다. 자아존중감 정도는 3.62점이었고 통계적으로 유의한 차이는 없었다. 성희롱 인식과 자아존중감은 양의 상관관계가 있었다(r=0.249, p<0.01). 성희롱 인식에 영향을 주는 융합 요인은 자아존중감, 학년, 성별, 성희롱 피해 경험이었으며 설명력은 12.1%였다. 이 연구는 성희롱 인식 수준을 향상시키고 성희롱 예방 및 대처를 위한 교육프로그램을 개발하는데 근거자료로 활용 될 것으로 사료된다. This study was to investigate the awareness and convergence factors of sexual harassment of 418 dental hygiene students in Jeollanam-do area. The data were analyzed using SPSS 22.0 program. Descriptive statistics of sexual harassment was 4.18, there were significantly different means with gender, grade and experience of sexual harassment. Descriptive statistics of self-esteem was 3.62. Awareness of sexual harassment and self-esteem was positive correlated. The convergence factors influencing awareness of sexual harassment were self-esteem, grade. gender and experience of sexual harassment. The explanatory power of the study was 12.1%. This study, expect to improve sexual harassment awareness levels, develop sexual harassment prevention and treatment, and use them as basics date to develop a program for education programs above.

한국 전통 된장 및 콩 추출물의 KB 세포에 대한 증식 억제효과
이성림,김종규,Lee, Sung-Lim,Kim, Jong-Gyu 한국환경보건학회 2005 한국환경보건학회지 Vol.31 No.5
The present study was designed to investigate whether traditional Korean fermented soybean paste(doen-jang) and soybean extracts have inhibitory effects on the growth of KB cell, an oral epithelioid cancer cell. When KB cell ATCC CCL-17 was cultivated for 48 flours with the addition of 0.5% of the five types or doen-jang extract, the growth of KB cell was inhibited by all types of extract, and ethyl acetate extract showed the highest inhibitory effect. In case of soybean extract, all types of extract also showed KB cell inhibitory effects, however, generally less than those of doen-jang extract. When ethyl acetate extract of doen-jang was added in different concentrations and KB cell was cultivated for 24 hours and 45 hours, strong inhibitory effect began to appear from the concentration of 1.25 mg/ml. Although soybean extract showed such a tendency, its effect was lower than that of doen-jang extract. These results indicate that doen-jang extract has inhibitory effect against KB cell, and particularly ethyl acetate extract has the highest effect. The effect of doen-jang extract might be possibly enhanced by the fermentation of soybeans. It is assumed that doen-jang extract may be used to develop nontoxic medicines for preventing and treating oral diseases.

This study was performed to investigate the anti-microbial activity of extract from Korean fermented soybean paste (doen-jang) against 16 types of oral microbes, and to determine the minimum inhibition concentration (MIC) of the extract for three major microbes causing human oral diseases (Streptococcus mutans, Porphyromonas gingivalis, and Candida albicans). The extract was prepared using ethyl acetate and it was treated with the oral microbes at a concentration of 5.00 mg/ml (0.5%). The anti-microbial activity and MIC were measured using broth dilution method. Significant reduction of microbial activities of 16 types of oral microbes occurred when the soybean paste extract was added to the broth compared to the control (p<0.01), and striking inhibition (more than 99%) was observed in ten types. S. mutans, which causes dental caries, showed MIC at a concentration of 1.25 mg/ml for the extract. P. gingivalis, which causes adult periodontal disease, showed MIC at a concentration of 2.50 mg/ml for the extract. C. albicans, which causes denture stomatitis and angular stomatitis, showed MIC at a concentration of 20 mg/ml for the extract. These results indicate that ethyl acetate extract of doen-jang showed strong anti-microbial effect against 16 types of oral microbes, and the anti-microbial effect of the extract against oral microbes was stronger against bacteria than against fungi. The anti-microbial effect might be possibly enhanced by the fermentation of soybeans.
