Objectives: The purpose of this study was to identify the influence of equality perception and organizational commitment on turnover intention of jobs among psychiatric hospital nurses. Method: Data were collected by questionnaire survey among 158 nurses working in 10 psychiatric hospitals from August 1st to September 30th. 2004. Results: The degree of turnover intention of jobs was significantly different by marital status, religion, qualification of psychiatric specialized nursing, monthly income and the location of hospitals. The correlation analysis showed that the turnover intention of jobs decreased as the equality perception and the organizational commitment increased. The hierachical multiple regression analysis showed that significantly related variables with turnover intention of jobs were religion, monthly income, equality perception and organizational commitment. The model explanation power was 53.1%. Conclusion: Because the equality perception explained 53.1% of variance of turnover intention among psychiatric nurses and organizational commitment was related with the turnover intention of nurses at psychiatric hospitals, activation strategy of organization must include the promotion strategy of equality perception and organizational commitment to decrease turnover intention of jobs among nurses.

"Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

Background : The increasing incidence of multidrug-resistant gram-negative bacteria causing nosocomial infections is an important clinical problem. Isepamicin is a recently developed aminoglycoside which has been known to have potent activity against gram-negative organisms. We evaluated the in vitro activities of isepamicin and other aminoglycosides against a large number of gram-negative organisms. Materials and Methods : We tested the in vitro antimicrobial activities of isepamicin, amikacin, gentamicin, and tobramycin against 566 gram-negative organisms collected between January 2006 and June 2006 in Asan Medical Center. Minimal inhibitory concentrations (MICs) were determined and interpreted according to the recommendations of Clinical and Laboratory Standard Institute (CLSI). The breakpoint MIC used for interpretation of isepamicin was MIC≤16 ㎍/mL as susceptible, 32 ㎍/mL as intermediate, and 64 ㎍/mL as resistant. Results : The MIC_(50)/MIC_(90) of isepamicln for Escherichia coli, Klebsiella pneumon/ae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Enterobacter cloacae were 1/2, 0.5/>128, 4/16, 16/>128, and 1/2 ㎍/mL, respectively. The susceptibilities for E. coli, K. pneumoniae, P. aeruginosa, A. baumannii, and E. cloacae were 100%, 86.4%, 89.7%, 50.0%, and 96.6%, respectively. For E. coli, K. pneumoniae, P. aeruginosa, and E. cloacae, isepamicln had better in vitro activities than gentamicin and tobromycin, and had similar activities with amlkacin. For A. baumanii, all four tested aminoglycosides had similar in vitro activities. Conclusion : Isepamicin had excellent in vitro activities against gram-negative organisms, except A. baumanii. The overall in vitro activities were similar with amikacin. 목적 : 그람 음성 세균은 다양한 지역사회 및 병원 획득 감염의 원인균이다. 최근에는 병원 감염을 일으키는 그람 음성 세균에서 항균제 내성균의 출현과 확산이 큰 문제가 되고 있다. Isepamicin은 최근에 소개된 gentamicin B의 유도체로 외국에서의 연구에 의하면 그람 음성 세균들에 대한 항균력이 우수함이 보고 된 바 있다. 본 연구에서는 우리나라의 임상 균주들을 대상으로 그람 음성세균에서 isepamicin의 시험관내 항균력을 기존의 아미노배당체 제재들과 비교하여 평가하고자 하였다. 재료 및 방법 : 2006년 1월에서 6월 사이에 서울아산병원 환자에서 분리된 Escherichia coli 113 균주, Klebsiella pneumoniae 110 균주, Pseudomonas aeruginosa 117 균주, Acinetobacter baumannii 108 균주, 그리고 Enterobacter cloacae 118 균주를 대상으로 isepaimcin, amikacin, gentamicin, tobramycin에 대한 최소억제농도(minimal inhibitory concentration, MIC)를 한천 희석법(Mueller-Hinton Agar)을 이용하여 측정하였다. 감수성여부는 CLSI 기준에 따랐으며, isepamicin은 MIC≤16㎍/mL를 감수성, MIC=32 ㎍/mL를 중등도 내성, MIC≥64 ㎍/mL를 내성으로 판정하였다. 결과 : Isepamicm의 E. coli, K. pneumoniae, P. aeruginosa, A baumannii, E. cloacae에 대한 MIC_(50)/MIC_(90)은 각각 1/2, 0.5/>128, 4/16, 16/>128, 1/2 ㎍/mL였고, 항균제 감수성률은 차례대로 100%, 86.4%, 89.7%, 50.0%, 96.6%였다. 기존 아미노배당체 제재들과 비교하면 E. coli, K. pneumoniae, P. aeruginosa, E. cloacae에서는 amikacin과 비슷한 감수성률을 보였고, gentamicin과 tobramycin보다 높은 감수성률을 보였다. A baumannii의 경우 isepamicin의 감수성률이 50.0%로 비교적 낮았지만 amikacin, gentamicin, tobramycin도 각각 50.0%, 46.3%, 47.2%의 감수성률을 나타내어 4가지 항균제가 모두 비슷한 항균력을 보였다. 결론 : Isepamicin은 그람 음성 세균들에 있어 기존의 아미노배당체 제재들과 비교했을 때 amikacin과는 동등한 시험관내 항균력을 보이고 gentamicin, tobramycin보다 뛰어난 시험관내 항균력을 보여 사용이 유망한 아미노배당체 중 하나라 생각된다.

문제: 뇌졸중 환자를 돌보는 간호현장에서는 급성기 뇌졸중 환자의 증상악화에 대한 조기사정과 적절한 대처가 매우 중요한 문제이다. 그러나 임상현장에서는 이를 객관화하고 수치화하여 모든 의료진이 의사소통할 수 있는 유용한 도구를 사용하고 있지는 못하는 실정이다. 이러한 문제를 해결하기위해 NIHSS(National Institute of Health Stroke Scale)를 신경과 진료의사를 중심으로활용하고 있지만 아직 간호현장에서는보편적으로사용하지 않고있다. 이에 뇌졸중환자간호에 NIHSS를 활용하여 뇌졸중 증상악화의 조기사정과 빠른 대처로 궁극적으로는 뇌졸중환자 간호의 질을보다 향상시키기 위하여 본활동이 시도되었다. 목적: 첫째, 간호사의 NIHSS 측정 신뢰도의 현수준을 점검하고 이를향상시키기 위한 프로그램을 개발·적용한다. 둘째, 간호사가급성기 뇌졸중환자에게 NIHSS 측정을 통하여 뇌졸중악화를 얼마나 예측할 수 있는지 분석하고 이를 향상시킬수있는 방법을 모색한다. 셋째, 궁극적으로 급성기 뇌졸중 환자의 증상악화의 조기 발견과치료를위한의료진의 올바른 대처지침을 마련하여 이를 적용한다. 의료기관: 경기도에 소재한 대학병원의 뇌졸중 집중치료실 질 향상 활동: 첫째, 간호사의 NIHSS 측정 신뢰도 향상을 위해 「NIHSS 간호사 교육 프로그램」을 마련하였다.

타투 시술 부위에 발생하는 알레르기 반응에 관한 연구

김미소(Mi-So Kim),김은수(Eun-Soo Kim) 사단법인 대한 문신사 중앙회 2021 한국반영구화장학회지 Vol.2 No.1

In modern times, tattoo culture has rapidly become common and popular, and not only do people who already have tattoos increase the number of tattoos, but also people who engrave tattoos regardless of gender and age are rapidly increasing. However, after the tattoo procedure, the allergy experience rate in tattoo areas was 32.5%, indicating that many of those who had tattoos had allergic reactions. The possibility of these potential side effects can occur to anyone, so it is important to think carefully before deciding to get tattooed, but the level of awareness about the potential risk factors of getting tattooed is worrisome. 86.2% of those who participated in the study said they would continue with the tattoo and were concerned about the quality of the tattoo rather than the side effects. Under the current circumstances, improving the awareness of tatooists and people who want to get tattoos is worth more than is necessary. Tattooist should fully explain to people who want to get tattoos for potential hazards that tattoos can cause. And if you were indifferent to professional awareness, professional improvement, and acquisition of expertise, you would have to wake up if you were consistent with a complacent attitude. The level of consciousness of "cultures" will soon serve as a means to determine the direction of tattoo culture in Korea.
