The purpose of this study was to test the hypothetical model designed to explain nursing students' perceived stress, coping levels, and stress outcomes. This hypothetical model was based on the Kim. Jung Hee(l987)' s stress model and stress-related literature. Exogenous variables were self-efficacy. hardiness. social support. and exercise. Endogenous variables were stress perception. coping levels. and stress outcomes. Empirical data for testing the hypothetical model consisted of 205 nursing students. SAS PC Program and LISREL 8.12a program were used for descriptive statistics and linear structural relationship(LISREL) modeling. The results were as follows. 1) The overall fit of the hypothetical model to the data was good( $x^2$=78.41(p=0.010), $x^2$/ df=1.50. RMSEA=0.05, standardized RMR= 0.05, GFI=0.95, AGFI=0.91, NNFI=0.90, NFI=0.94). 2) The results of statistical testing of the hypotheses were as follows. (1) As expected. self-efficacy had a significant effect on stress perception. But. hardiness. social support, and exercise did not have a significant effect on stress perception. Self-efficacy, hardiness. social support, and exercise explained 12% of the total variance of stress perception. (2) As expected, self-efficacy, hardiness, social support, exercise, and stress perception had a significant effect on coping behavior, Self-efficacy, hardiness, social support, exercise, and stress perception explained 53% of the total variance of coping behavior. (3) As expected, stress perception and coping behavior had a significant effect on stress outcomes. Stress perception and coping behavior explained 84% of the total variance of stress outcomes. In conclusion, the hypothetical model of this study was confirmed in explaining and predicting stress perception, coping levels, and stress outcomes in nursing students. And these findings suggest the need to develop nursing intervention to enhance self-efficacy, hardiness, social support, and exercise to decrease the harmful outcomes of stress.

이미라,이원희,Lee, Mi-Ra,Lee, Won-Hee 한국호스피스완화의료학회 2001 한국호스피스.완화의료학회지 Vol.4 No.1

본 연구는 2000년 상반기 한 대학 병원의 호스피스 자원봉사자 교육에 참여한 84명의 설문 응답자를 대상으로 하여 호스피스 자원봉사자의 죽음에 대한 태도와 말기 환자 돌봄에 대한 요구, 말기환자와 가족 돌봄에 대한 태도를 알아보기 위한 서술적 연구이다. 개방형 질문을 이용한 자료에서 응답자의 대부분이 죽음에 임박한다면 가족에 대한 염려와 걱정, 죽음의 고통, 내세의 두려움이 가장 큰 불편함이 될 것이라고 답했고, 사랑과 관심 있는 임종 간호에 대한 요구를 보였으며, 죽음이라는 위기 상황을 극복할 수 있는 가장 큰 자신의 자원을 신앙심으로 인식하고 있다. FATCOD 도구에서(Cronbach ${\alpha}$는 0.778 이었으며) 말기환자와 가족 돌봄이 가치 있는 일이라고 여김에도 불구하고 죽음에 대해 이야기하는 것과 말기환자와 감정을 나누는 것은 여전히 어렵고 불편한 것임을 나타냈다. 또한, 말기환자 돌봄에서 가족 참여는 필수적인 것이고, 말기환자가 남은 여생을 가장 잘 살아갈 수 있도록 정상적인 환경을 유지해야 하며, 죽음이란 모든 인간이 자연스럽게 받아들여야 하는 삶의 한 과정임을 인식하고 있다. Purpose : The purpose of this study was to identify attitudes of hospice volunteers toward care of for terminally ill patients. Method : This was a descriptive study with a sample of 84 adults who were registered for a hospice volunteer education program at Severence Hospice Center. The Frommelt (FATCOD) scale on attitudes toward the care of the dying (Cronbach alpha=.778) and an open ended questions on "what if you only have 6 months to live" were used to collect the data. The data was analyzed using SPSS/W and content analysis. Results : 1) The hospice volunteers were mostly female, with an average age of 45 years, half of them were college graduates and their religious preference was Protestant. 2) The participants of this study demonstrated positive attitudes to care for the dying which is in coherence with hospice philosophy and principles. However they indicated difficulties in maintaining close relationships with people who are dying, and in communicating and sharing, and encouraging those who are dying to express their feelings. In the open ended questions, they identified that their most important issues would be guilt feelings toward their children, family concerns, and the burden of unfinished business in their lives. They also identified the fear of pain in the dying process and fear of the afterlife. The care they would like to receive was to have peace of mind, have a good listener, spiritual counselling, and pain relief and to be respected as a human being. The source of strength would be faith in God and they would like to overcome their of dying. The FATCOD scale has limitation in describing and identifying the need and attitude toward the care of the dying revisions were made. Conclusion : We all are the potential clients for the hospice rare. In a hospice volunteer education program, communication and interpersonal skill are essential. The fear of dying, afterlife, concerns about family with children, and human dignity are major concerns in hospice and palliative care.

Objectives: The purpose of this study was to evaluate the association of smoking and drinking status with gingival symptoms among the adolescents in Korea. Methods:We used the data from the web-based survey of the National Korean Youth Risk Behavior of Korean Center for Disease Control in 2016. The study subjects were 65,528 adolescents from middle- and high schools. Data were analyzed by SPSS Ver. 19.0. Multiple regression analysis was used to assess the factors related to gingival symptoms. Results: We observed 1.52 of odds ratio (OR) for gingival symptoms for those who smoked only without drinking in middle schools. In addition, we had ORs of 1.29 or 1.69 for those who drank only without smoking, or who smoked and drank in the middle schools, respectively, compared to nonsmoking nondrinkers. Risk of gingival symptoms for those who drank only or who smoked and drank in high schools were 1.18 or 1.17 times higher than nonsmoking nondrinkers. Conclusions: Smoking and drinking status among the adolescents are the risk factors to develop gingival symptoms. The problem of smoking and drinking in the adolescents should be considered when establishing the policies and institutions to improve oral health targeting the adolescents.

간호학생을 대상으로한 건강관련 강인성 도구(HRHS)의 신뢰도와 타당도 검증 및 수정

이미라,Lee, Mi-Ra 한국지역사회간호학회 2000 지역사회간호학회지 Vol.11 No.1

The purpose of this study is to test the psychometric properties of the Korean version of the Health-Related Hardiness Scale(HRHS) in a sample of Korean nursing students. The korean version of HRHS was administered to 234 nursing students including 135 college students and 99 university students. The Korean version of HRHS was measured on a 6 Likert scale, assessing three factors of HRHS : control, commitment, and challenge. Internal consistency was used to test the instrument's reliability. The internal consistency of the scale was measured using a coefficient alpha. The coefficient alpha was .69(control), .49(commitment). and .69(challenge), Item analysis and confirmatory factor analysis (CFA) were used to test the instrument's construct validity. The item analysis identified that there were 13 items. which were lower than the .25 item-total correlation. CFA revealed that the scale's fadoral validity was not proper by showing unfit indices(RMSEA .07. stand, RMR .09. GFI .71). According to the findings of this study, the reliability and construct validity of the Korean version of HRHS is not satisfactory in the sample of nursing students. As a result. the researcher modified the scale through item analysis and repetitive CFA process, and proposed the revised 25-item Korean version of HRHS for nursing students. The revised scale's reliability(control .74, commitment .73. challenge .77) and factorial validity were within acceptable levels. The item analysis identified that there was no item, which is lower than the .25 item-total correlation. CFA revealed that the scale's factoral validity was proper by showing fit indices(RMSEA .08 stand. RMR .08. GFI .80).

포도주스 침지 제조 흑삼의 Ginsenoside Rg₃ 함량 변화와 Acetylcholinesterase 억제효과

이미라,윤범식,손백신,류뢰,장동량,왕춘년,왕젠,이선영,모은경,성창근,Lee, Mi-Ra,Yun, Beom-Sik,Sun, Bai-Shen,Liu, Lei,Zhang, Dong-Liang,Wang, Chun-Yan,Wang, Zhen,Ly, Sun-Young,Mo, Eun-Kyung,Sung, Chang-Keun 고려인삼학회 2009 Journal of Ginseng Research Vol.33 No.4

흑삼의 속성제조와 ginsenoside $Rg_3$ 함량을 극대화하고자 흑삼 제조시 포도주스에 24시간 침지한 후 $120^{\circ}C$에서 30분간 3회 반복 증숙하여 흑삼을 제조한 후 HPLC 방법을 이용하여 ginsenosides를 분석하였다. 포도주스에 침지하여 제조한 흑삼의 ginsenoside $Rg_3$ 함량은 10.91 mg/g으로 구증구포 방법으로 제조한 흑삼보다 약 2배 가량 함량이 증가되었다. 총 사포닌 함량은 14.97 mg/g으로 전통적인 구증구포 방식으로 제조한 흑삼 (12.79 mg)보다 그 함량이 높았다. 흑삼의 단회투여 (200 mg/kg, p.o.)에 의한 뇌조직 AChE 활성은 투여 24시간 후에 유의적으로 억제되는 효과를 보여주었다. 따라서 본 연구에 적용한 새로운 제조방법은 ginsenoside $Rg_3$를 강화하는 흑삼의 속성제조에 효과적인 방법으로 판단된다. 또한, AChE 활성억제를 통해 흑삼이 뇌기능 개선에 대한 잠재적인 효능을 가지고 있는 것으로 사료된다. This study was conducted to develop a new method for enhancing ginsenoside $Rg_3$, which is abundant in black ginseng. The cognition-enhancing effect of black ginseng extract was investigated via the assay of acetylcholinesterase (AChE) activity. Black ginseng I was prepared through the traditional method (by steaming and drying nine times repetitions). Black ginseng II, on the other hand, was prepared by steaming the ginseng three times at $120^{\circ}C$ for 30 min after soaking it in grape juice for 24 h. The ginsenosides of white, red, and black ginseng I, and II were investigated using the HPLC method, respectively. In black ginseng II, the ginsenoside $Rg_3$ contents, which cannot be found in white ginseng, amounted to 10.91 mg/g, approximately 18 times more than that in red ginseng. In the in-vivo study, black ginseng extract (200 mg/kg, p.o.) inhibited the AChE activity after 24 h by a single administration in the brain. Thus, the new manufacturing method for black ginseng was found to more effective in the conversion of ginsenoside $Rg_3$ compared to the traditional method. Black ginseng may also have the effect of preventing the cognitive impairment induced by cholinergic dysfunction.
