최근 코로나 팬데믹으로 인해 배달음식을 즐겨 먹는 사람들이 증가하고 있다. 이로 인해 운동량 부족과 고칼로리 음식 섭취 등으로 불균형적인 영양소가 섭취가 되고 있다. 사람들의 올바른 식생활을 위해서 개인 식생활 데이터를 수집하고 분석해서 머신러닝을 이용해서 개인 맞춤형 식단을 제공하고자 한다. 본 논문에서는 머신러닝에 사용될 사람들의 식생활 데이터를 수집목적으로 개인의 식생활을 기록해서 데이터베이스에 저장하는 모바일 어플리케이션을 개발한다.

The purpose of this study is to investigate the mediating effect of child care teachers" professional perception on the relationship between professional learning environment and their efficacy as teachers. For the purpose of the study, a total of 207 copies of the questionnaire were distributed to teachers in Busan, and the final 190 teachers" data were analyzed. Three different inventories were utilized. One was a professional perception inventory consisting of 3 domains and 55 items, the second was a teacher efficacy inventory consisting of two domains and 25 items, and the third was a professional learning environment inventory consisting of 4 domains and 36 items. In order to investigate the relationship of each variable, we conducted a correlation analysis and performed hierarchical regression analysis to verify the mediating effect of professional perception on the relationship between professional learning environment and teacher efficacy. The conclusions of this study are as follows. First, there were significant correlations among professional learning environment, professional perception and teacher efficacy. Second, the professional perception completely mediated the relationship between professional learning environment and teacher efficacy. The results of this study show professional perception should be considered as an important factor to promote professional learning environment of child care teachers and their efficacy. In other words, teacher efficacy can be developed through the enhancement of professional perception and the improvement of professional learning environment by providing various training programs for child care teachers.

This study investigated how teachers monitored students’ various responses while they applied “five practices for orchestrating productive mathematics discussions” by Smith and Stein (2018) to their mathematics lessons. The participants were two third-grade teachers and two fourth-grade teachers. The implementation levels of teacher monitoring were analyzed by three sub-elements. In addition, the factors influencing the implementation of monitoring were explored. The results of this study showed that the teachers had difficulties tracking continuously which approaches students were using. The results of this study also demonstrated that the implementation level in terms of the three sub-elements was different, even though the overall implementation level of monitoring was the same. The factors influencing teacher monitoring included mathematical tasks selected, anticipating students’ responses, using monitoring charts, and teachers’ orientation. Based on these results, implications for implementing effective monitoring were suggested.

N/A To assess the effect of different dosages of interferon alpha-2b(Intron A), 43 patients with chronic hepatitis B were assigned randomly to 3 groups: Group A, l5 patients, received Intron A in a dose of 3 million units (MU) thrice weekly for 12 weeks (total dosage: 1.8×108); Group B, 14 patients, received in a dose of 3 MU every day for the first month and thereafter every other day for the following 4 months (total dosage: 2.7×108); Group C, 14 patients, received no specific therapy. They included 34 men and 9 women, between 17 to 53 (mean 35) years of ages, with elevated serum AST and ALT levels; 41 to 879 (mean 289), and 57 to 334 (mean 288)U/L, respectively. Needle biopsies of the liver before therapy revealed chronic active hepatitis in 35 cases and active cirrhosis in 7 cases, The average follow-up period was 12 months. The results were as follows; 1) During the therapy, serum ALT levels returned to normal in 12 (80%) of Group A and in 12 (86%) of Group B, but increased again in 8 out of 12 in Group A, and in 4 out of 12 in Group B during the follow-up period, In Group C, the ALT level returned to normal in 3 out of 15 during the same period. 2) Serum HBeAg became negative in 6 out of group A in 11 out of Group B, but became positive again in 2 out of 6 in Group A and in 3 out of 11 in Group B during the follow-up period; The sero-negative conversion rate of HBeAg at the end of this study was 27 in Group A and 57% in Group B. In Group C, the sero-conversion of HBeAg was found in 2 out of 14 (14%). A statistically significant difference was noted between Group B and Group C (p<0.05). 3) Comparison of responders and non-responders in the treated group showed no differences in age, sex, liver fuction test, and tissue pathology. 4) Although flu-like symptoms (100%), loss of hair l (10%), and leukopenia (40%) were observed in the treated group, no serious side effects necessitating discontinuation of the therapy were observed. In conclusion, this study showed that the effect of interferon on patients with chronic hepatitis B might be different depending on the dosage and duration of therapy and that with increased dosage, the response rate could to be higher. But further studies should be carried out to determine the exact duration and dosage of therapy in these patients.
