알칼리 용해성 회합 증점제의 합성 및 유성학적 물성에 관한 연구
서은현,이덕연,이종길,김중현 ( Eun Hyun Seo,Doug Youn Lee,Jong Kil Lee,Jung Hyun Kim ) 한국공업화학회 1997 공업화학 Vol.8 No.4
본 연구에서는 associative macromonomer로서 비이온성 vinyl surfactant ester(alkyloxy poly(ethyleneoxy)_n ethyl acrylate)[VSE]를 사용한 유화중합을 통하여 회합형 아크릴 증점제를 합성하고, 유성학적 물성을 고찰하였다. VSE의 소수성 말단기의 탄소수, ethoxylation 정도에 따라 회합형 증점제의 중점효과가 크게 영향을 받았다. VSE의 종류를 고정하고, 공단량체 조성을 달리하여 제조한 아크릴 회합형 증점제의 수용액 점도 변화를 고찰한 결과, VSE의 양이 늘어날수록 증점효과가 증가하였다. 이것은 VSE의 소수성 말단기의 상호작용에 의한 회합 증점 메카니즘에 의해 증점효과가 향상되었기 때문이다. 또한 사슬전이제에 의한 분자량이 감소할수록 hydrodynamic volume이 작아져 증점효과가 감소하였다. Associative acrylic thickeners were prepared by emulsion copolymerization using nonionic vinyl surfactant esters as an associative macromonomer and their rheological properties were investigated. The thickening efficiency was shown to depend on the chain length of terminal hydrophobe and degree of ethoxylation of VSE. For a given VSE, increasing the content of VSE enhanced the efficiency of the resulting polymers as a thickener. It was attributed to the intermolecular association of terminal hydrophobes of assoaative thickener in aqueous solution. The chain transfer agent caused to reduce the molecular weight of associative thickener, resulted in decrease of thickening efficiency.

Purpose: The purpose of this study was to examine the effects of an education program for AIDS prevention on knowledge about AIDS and attitudes towards AIDS/people with AIDS among male-high school students. Methods: A research design used in this study was a randomized and non-synchronized control group pre-and-post test. The participants were 560 male students from five high schools in Seoul and Gyeonggi province. In each school two classes were randomly assigned to each the experimental or control group. The contents of the education program for AIDS prevention consisted of six parts with a total of 50 minutes. The data were analyzed using t-test and chi-square test with SPSS WIN program version 13.0. Results: There were significant differences in knowledge and attitudes between experimental and control groups. The experimental group showed higher scores in knowledge and more positive attitudes than the control group. Conclusion: The education program was effective in increasing positive attitudes towards AIDS/people with AIDS among male high school students. Further application of the program with female students is needed before the results of the study can be generalized.
Prioritization of Research Topics of Korean Oncology Nurses
Lee, Eun-Hyun(이은현),Chung, Bok Yae(정복례),Chun, Nami(전나미),Oh, Pok Ja(오복자),Cho, Soo-Yeon(조수연) 대한종양간호학회 2013 Asian Oncology Nursing Vol.13 No.4
Purpose: The aim of this study was to determine the prioritization of research topics by Korean oncology nurses. Methods: A descriptive and cross-sectional survey was conducted via the website of the Korean Oncology Nursing Society, with participation sought by email from all of its members. Results: Overall, ‘pain’ and ‘quality of life’ were the most important among the 74 topics, ‘cancer prevention’ was ranked 47th, while ‘informatics’ and ‘telehealth’ were ranked 62nd and 72nd, respectively. Korean oncology nursing research needs to be expanded to include community-based cancer prevention. In addition, research on informatics and telehealth in the oncology nursing area is necessary given the current dramatic changes in the implementation of information technology in medical services. Conclusion: These findings may contribute toward the development of a Korean oncology nursing research agenda and the provision of information to funding agencies with respect to setting the priorities of oncology nursing research.

목적 : 본 연구 목적은 암 환자의 삶의 질에 대한 국내 연구논문을 분석 평가하여 선행연구의 단점을 보완한 후속 연구의 방향을 제시하기 위함이다. 대상 및 방법 : 전남대학교 보건연구 정보센타, KoreaMed 및 의학연구정보센타의 DB Bank를 검색하여 ‘삶의 질’과 ‘암’이라는 용어가 포함된 논문 31편을 선정하였다. 선정된 연구논문을 암 부위, 삶의 질 정의에 대한 개념적 영역(domains), 사용된 독립변수(예측변수), 연구설계(단면적/종적연구), 측정의 주체(자가측정/대리측정), 사용된 도구(단일도구/일련의 도구 세트), 질문지 번역과정(번역-역번역), 신뢰도, 타당도, 점수계산방법 및 연구결과에 따라 분석하였다. 결과 : 전체 31편의 연구논문 중 약 반이 여러 종류의 암 환자를 대상으로 실시되었고, 삶의 질의 정의에 대해서는 많은 연구에서 다차원적으로 정의하였다. 연구설계는 약 30%의 논문만이 종적연구설계를 하여 삶의 질 변화에 대한 연구를 하였다. 삶의 질 측정도구로는 거의 전 연구에서 환자가 직접 측정하는 질문지 방법을 이용하였으나, 도구의 선택에 있어 신뢰도와 타당도에 대해서는 고려하지 않은 편이다. 또한 외국에서 개발된 질문지를 번역하여 사용할 때 변역-역번역 과정을 통해 한글로 번역한 도구는 하나도 없었다. 측정된 삶의 질 계산방법은 전부 전통적인 방법인 평균이나 합으로 계산하였다. 연구에서 삶의 질에 영향을 미치는 독립변수로 검정되었던 변수들은 다양하지 않았다. 결론 : 앞으로 암 환자의 삶의 질에 대한 국내 연구가 나아가야 할 방향은 치료과정에 따른 삶의 질 변화 파악을 위한 종적 연구설계의 시도와 신뢰도와 타당도가 수립된 적절한 측정도구의 사용, 그리고 삶의 질에 영향을 미치는 제 변수들에 대한 반복적 연구 및 새로운 변수 파악을 위한 연구라고 할 수 있다. Purpose : The purpose of the present study was to analyze and evaluate prior studies published in Korea on the cancer-related quality of life, in order to make recommendations for further research. Materials and Methods : A total of 31 studies were selected from three different databases. The selected studies were analyzed according to 11 criteria, such as site of cancer, domain, independent variable, research design, self/proxy rating, single/battery instrument, translation/back translation, reliability, validity, scoring, and findings. Results : Of the 31 studies, approximately half of them were conducted using a mixed cancer group of patients. Many of the studies asserted that the concept of quality of life had a multidimensional attribute. Approximately 30% were longitudinal design studies giving information about the changes in quality of life. In all studies, except one, patients directly rated their level of quality of life. With respect to the question-naires used for measuring the quality of life, most studies did not consider whether or not their reliability and validity had been established. In addition technique. All studies used sum or total scoring meth-ods when calculating the level of quality of life. The types of variables tested for their influence on quality of life were quite limited. Conclusion : It is recommended that longitudinal design studies be performed using methods of data collection whose validity and reliability has been confirmed, and studies be conducted to identify new variables having an influence on the quality of life.
