재가방문 치매 요양보호사의 근무환경이 인간중심돌봄에 미치는 영향
유정옥,장두남 한국직업건강간호학회 2023 한국직업건강간호학회지 Vol.32 No.4
Purpose: The purpose of this study was to examine the impact of the working environment on person-centered care for home visiting dementia caregivers. Methods: Participants in this study were 146 caregivers, with the least 6 months of experience working at visiting care centers in Busan, and used a total of 133 questionnaires suitable for analysis. Data were collected from June 9 to July 20, 2023, and were analyzed using descriptive statistics, t-test, ANOVA, pearson’s correlation coefficients, and multiple linear regression using IBM/SPSS 27.0. Results: As a result of multiple linear regression analysis, organizational factors (β=-.37, p<.001), job-related factors (β=-.27, p=.001), and religion (β=.18, p<.013) were factors affecting person-centered care of home visiting dementia caregivers, and working environment explained 37% (F=10.63, p<.001) of person-centered care. Conclusion: Based on the results of this study, the exploration of strategies to improve the working environment will be necessary in order to increase person-centered care for home visiting dementia caregivers.
Pyrrole유도체와 Diethyl Azodicarboxylate의 부가반응

N-substituted pyrrole들, 즉 1-(p-acetylphenyl)-(6a), 1-(m-acetylphenyl)-(6b), 1-(p-bromophenyl)-(6c),1-(p-nitrophenyl)-(6d), 1-(m-nitrophenyl)-(6e), 그리고 1-(p-methoxyphenyl) pyrrole(6f)을 합성하여 이들과 diethyl azodicarboxylate와의 부가반응을 논하였다. 또한 이들 치환체에 의한 감응효과에 다른 반응상의 차이점을 논하였으며, 모든 반응이 1:1 및 1:2 Michael 형태를 부가반응으로 진행됨을 생성물의 IR, UV, NMR spectra로 확인하였다. The following N-substituted pyrroles, that is, 1-(p-acetylphenyl)-(6a), 1-(m-acetylphenyl)-(6b), 1-(p-bromophenyl)-(6c), 1-(p-nitorphenyl)-(6d), 1-(m-nitrophenyl)-(6e) and 1-(p-methoxyphenyl)pyrrole(6f) were prepared by the known methods, and the addition reactions of these compounds with diethyl azodicarboxylate were examined. The difference in reactivities was discussed in terms of inductive effects of the pyrrole derivatives. Both of the 1:1 and 1:2 Michael-type adducts were synthesized by these reactions and identified by IR, UV and NMR spectra.
Pyrrole 유도체와 Diethyl Azodicarboxylate의 반응속도론적 연구

Pyrrole유도체들과 diethyl azodicarboxylate의 Michael부가반응의 반응기구를 규명키 위하여 유전상수를 달리하는 몇가지 용매에서 자외선 분광 광도계를 이용하여 그 반응속도를 측정하였다. 실험결과 이 반응은 2차 반응임이 밝혀졌고, 그 활성화 entropy는 큰 음(negative)의 값을 가졌음을 알았다. 이와 같은 사실들은 이 반응의 반응속도 율속단계가 6원자 고리형의 전하가 분리된 천이상태를 형성하고 있다는 추론의 정당함을 뒷받침하여 주고 있다. The rate constants for Michael-type addition reaction between diethyl azodicarboxylate and N-substituted pyrroles were measured by UV spectrophotometer in various solvents. The reaction was found to be the second-order, and characterized by a large negative entropy of the activation. These results indicate that the rate-determining step in Michael-type addition reaction of diethyl azodicarboxylate to N-substituted pyrroles would be the formation of a zwitter ionic 6-membered cyclic form.
