Dendropanax morbifera Lev. (D. morbifera) is a species of native tree that is widely distributed in the southern parts of Korea including Jeju island. Since ancient times, leaves, stems and roots of the plant have been used as folk remedies to treat dermal complications and other infectious diseases. The present study was conducted to investigate the diabetes treatment effect of the plant hot water extracts (DMWE) using streptozotocin-induced diabetes in rats. In this study, thirty male 5-week-old Sprague-Dawley rats were used. The rats were divided into six groups of five rats per treatment group and administered for 4 weeks. The treatment group were normal control rats received saline (NC), diabetic control rats received saline (DC), diabetic rats treated with 500 mg/kg body weight (BW) of metformin (DT), diabetic rats treated with 50 (DM-50), 100 (DM-100) and 200 mg/kg BW (DM-200) of DMWE. After 14 days of administration of DMWEs, the BW of all groups treated with DMWEs increased significantly compared to that of DC (P<0.05), however, the BW of DM-100 and DM-200 showed no significant difference compared to that of DT. Blood sugar levels in DT and DM-200 decreased below 200 mg/dL at 3 weeks after administration of DMWEs, and at 4 weeks after treatment, blood glucose levels in DT, DM-100 and DM-200 decreased within the normal range. At 4 weeks after treatment of DMWE, the glycated hemoglobin (HbA1c) concentrations in all groups administered with DMWEs showed no significant difference compared to those of NC and DT. The HbA1c concentrations of DM-100 and DM-200 showed significant reduction compared with that of DC (P<0.05). In blood biochemical parameters, the levels of AST, ALT and BUN in DM-100 and DM-200 showed no significant difference compared to those in NC and DT, however, significant differences compared to that of DC (P<0.05). From the above results, DMWEs have been identified to be effective in the treatment of diabetes.

Objectives: The objective of this study was to identify the influence of shift work on sleep quality, daytime sleepiness, and perceived errors in nursing work among hospital nurses. Methods: The study subjects were 209 hospital nurses working in two general hospitals in South Korea. The data were collected through self-administered questionnaires in May 2013. Sleep quality was measured with Korea Pittsburgh Sleep Quality Index (PSQI-K), daytime sleepiness with Epworth Sleepiness Scale (ESS), and perceived errors in past 6 months in nursing work with the tool developed in this study. Results: The sleep quality was significantly worse in rotating shift nurses than fixed day nurses. However, the odds ratio (OR) of 1.92 [95% confidence interval(CI): 0.58-6.37] adjusted for sociodemographic variables, health behaviors, and working environment in logistic regression was not significant. There was no significant difference in the daytime sleepiness between rotating shift nurses and fixed day nurses in both simple and multivariable analyses. There were significantly more perceived errors in rotating shift nurses than fixed day nurses. However, the OR of 1.26 (95% CI: 0.38-4.21) adjusted for sociodemographic variables, health behaviors, working environment, sleep quality, and daytime sleepiness in logistic regression was not significant. Depression (OR=3.31, 95% CI: 1.11-9.84) and daytime sleepiness(OR=1.18, 95% CI: 1.07-1.30) were significantly associated with perceived errors in logistic regression. Conclusion: This study suggested shift work among hospital nurses had no independent influence of sleep quality, daytime sleepiness, and perceived errors. However, daytime sleepiness had independent influence of perceived errors. More studies are warranted to get more reliable conclusion. Key words: Rotating shift nurses, Nursing work, Clinical nurses, PSQI-K

Salmonella typhimurium (S. typhimurium) is gram-negative bacteria that have been known for the main cause of food-borne disease and typhoid fever in various hosts including humans. Salmonellosis is a major bacterial zoonosis caused by S. typhimurium. Multidrug-resistant strains of Salmonella spp. have increased over the last several decades and recently have caused more serious problems in public health. The present study was investigated the antibacterial effect of Coptidis rhizoma, Poria cocos Wolf and Paeonia japonica extracts against S. typhimurium, and therapeutic effect of sodium chlorate (SC), a mixture of Coptidis rhizoma, Poria cocos Wolf and Paeonia japonica (1:1:1) extracts (HE) and the combination of SC and HE for murine salmonellosis. In the antibacterial effect of Korean traditional herb extracts against S. typhimurium, the inhibition strength at the concentration of 1.0 mg/ml followed the order: Poria cocos Wolf > Paeonia japonica > Coptidis rhizoma. On eight hours after incubation of S. typhimurium, the combination of SC and HE at the dose of 0.5, 1.0 and 2.0 mg/ml were inhibited the growth of S. typhimurium by 28.0, 39.9, and 59.0%, respectively. For 12 days after single challenge with S. typhimurim, forty female ICR mice were divided into four experimental groups which were orally administered with saline, SC (15 mM), HE (1.0 mg/ml) and the combination of SC (15 mM) and HE (1.0 mg/ml), respectively. On the 7th day after infection, the mortality of mice administered with saline, HE, SC and the combination of HE and SC was 30, 20, 10, and 0%, respectively. On the 12th day after infection, the mortality of mice treated with saline, HE, SC and a combination of HE and SC was 100, 90, 90 and 70%, respectively. The results of this study indicate that a combination of SC and HE has a potential treatment for murine salmonellosis. To evaluate the safety of the exposure to various doses of the combination of SC and HE in 5-week-old ICR mice, forty mice were divided into four equal groups and treated with different times of the combination of SC (15 mM) and HE (1.0 mg/ml): ×0, ×1, ×2 and ×4 via the drinking water for 7 consecutive days. In the hematological and blood biochemical analysis, all parameters in the treated groups were not significantly difference compared to those of the control group. Thus, 7-day administration of the combination of SC (15 mM) and HE (1.0 mg/ml) at four times does not affect the hematologic and blood biochemical parameters. In conclusion, this study suggested that it was very safe to administrate the combination of SC (15mM) and HE (1.0 mg/ml) at the dose of four times, and it is also expected that the combination can be used for the substitution of antibiotics on the murine salmonellosis. 본 논문은 사람에서 장티푸스와 식중독을 일으키는 살모넬라균 (Salmonella typhimurium)에 대하여, 항균효과가 알려진 한약재들(황련, 백복령, 백작약)의 열수추출물을 이용하여, 항균효과를 확인하였으며, 세포내 기생하는 살모넬라균에 대한 사멸효과가 있는 것으로 보고된 염소산나트륨과 한약재 열수추출물의 합제를 살모넬라균을 감염시킨 마우스에 투여하여 치료효과를 확인하였다. 한약재 추출물의 항균효과를 확인하기 위하여, 살모넬라균을 평판배지에 배양하여, 황련, 백복령, 백작약 열수추출물을 농도별로 첨가한 paper disc를 올려놓고, 형성된 저지환의 크기를 측정하여 각 물질의 항균활성 정도를 측정하였다. 액체배지 내 살모넬라에 대한 한약재 추출물과 나트륨염의 억균 효과를 확인하기 위해, 액체 영양배지에 살모넬라균을 일정 농도로 배양한 다음, 황련, 백복령, 백작약 등의 열수추출물과, 염소산나트륨을 첨가하여 8시간 동안 배양하면서 균수의 변화를 관찰하였다. 마우스 살모넬라 감염실험을 위해, ICR 마우스 암컷 40마리를 살모넬라균에 모두 감염시킨 다음, 대조군에는 일반 음용수를, 실험군 Ⅰ에는 염소산나트륨을 첨가한 음용수를, 실험군 Ⅱ에는 한약재복합추출물을 그리고 실험군 III에는 염소산나트륨과 한방복합추출물의 합제를 첨가한 음용수를 각각 급여하면서, 12일 동안 마우스의 생존율을 관찰하였다. 한약재추출물과 염소산나트륨 합제의 안전성 실험을 위해, 5주령 ICR 마우스 암컷 40마리를 이용하여, 대조군에는 일반 음용수를, 실험군 Ⅰ, II, II에는, 앞서 살모넬라 마우스 감염실험에서 효과가 있었던, 염소산나트륨과 한약재복합추출물의 합제를 각각 1, 2, 4배로 하여 음용수에 첨가하여 7일 동안 급여하였다. 마우스의 체중은 실험 시작 전과 실험종료 후에 각각 측정하였으며, 실험종료 시점에는, 마우스를 마취시킨 다음, 심장천공법으로 마우스의 혈액을 채취하여 혈액학적·혈액생화학적 분석을 실시하였다. 살모넬라균에 대한 한약재추출물의 항균효과에 있어서, 황련, 백복령, 그리고 백작약은 모두 1,000 μg/ml 농도에서 살모넬라균에 대해 항균활성을 나타내었으며, 백복령, 백작약, 황련 순서로 살모넬라에 대한 항균활성을 나타내었다. 액체배지 내 살모넬라 억균 효과에 있어서는, 한약재복합추출물을 투여한 모든 군(0.5, 1.0, 2.0 mg/ml)에서 배양 4시간부터 무투여 대조군에 비해 통계적으로 유의하게 살모넬라균의 증식을 억제하는 결과를 나타내었다(p<0.05). 마우스 살모넬라 감염실험 결과, 무투여 대조군의 경우, 감염 후 9일째 모두 폐사하였으나, 염소산나트륨을 투여한 군과 한약재복합추출물을 투여한 군은 모두 실험종료 시까지 1 마리가 생존하였으며, 염소산나트륨과 한약재복합추출물 합제를 투여한 군은 실험종료 시점에 3 마리가 생존하여 높은 생존율을 나타내었다. 한약재추출물과 염소산나트륨 합제의 안전성 실험 결과, 대조군과 처리군들 사이에 체중간의 유의한 차이는 관찰되지 않았으며, 혈액학적·혈액생화학적 지표들에 있어서, 대조군과, 염소산나트륨과 한약재복합추출물 합제를 농도별로 투여한 군들 사이에서 통계적으로 유의한 차이를 보이지 않았으며, 약제 투여군들 사이에서도 용량 의존성이 관찰되지 않았다. 본 연구 결과로 부터, 황련, 백복령, 그리고 백작약의 열수추출물 합제는 살모넬라균에 대해 높은 항균효과를 나타내었으며, 염소산나트륨과 한약재복합추출물 합제는 마우스의 살모넬라증에 대해 높은 치료효과를 보였다. 또한, 염소산나트륨과 한약재복합추출물 합제는 마우스의 혈액학적·혈액생화학적 분석 결과에서 매우 안전한 것으로 확인되었다.

Purpose: This study aims to provide primary data for improvement by identifying the working environment, job stress, physical fatigue, and job satisfaction levels for administrative staff working at medical institutions in the COVID-19 pandemic situation and examining factors affecting job turnover. Methods: In this study, six medical institutions designated as screening and relief hospitals with more than 100 beds and less than 300 beds in the J city area of ​​Gyeongnam Province, except for medical personnel (doctors and nurses) who directly participate in patient treatment, were hospital workers who were working as administrative personnel. Data were collected by using a questionnaire. During the collection period, from October 20, 2021, to October 23, 2021, all 140 copies were collected for 140 people. The collected data were analyzed using SPSS/WIN 23.0 program, and real number and percentage, mean and standard deviation, independent t-test, ANOVA, scheffe test, Pearson correlation coefficients, and hierarchical rarity analysis were used. Results: 1. In terms of demographic, job-related, and COVID-19 work-related characteristics of the participants, there were 111 women (79.3%), the average age was 35.06±10.33 years, 73 'unmarried' status (52.1%). As for the education level, 87 people (62.1%) had ‘college or less’, 65 people (46.4%) from the 'general affairs department', working experience averaged 8.83±9.39 years, and 116 people were 'employee/manager' in the job position. Seventy-seven people replied that the salary level was ‘normal’ (55.0%), 58 people were ‘dissatisfied’ (41.4%), 131 people were ‘regular workers’ (93.6%), and 74 people did not exercise regularly (52.9%). Regarding the health status of the workers compared to the pre-COVID-19 situation, 85 people replied that they were ‘healthy’ (60.7%), 76 people said ‘yes’ to have experienced turnover (54.3%), 69 people have had ‘no contact’ with suspected COVID-19 patients (49.3%) while 55 people have had '1-5 times' of experience (39.3%). Among all participants, 115 people (82.1%) said 'no' for the quarantine experience. Also, as a result of multiple response analyses for increased work after the outbreak of COVID-19, 112 people have gone through ‘Fever check’ (80.0%). 2. Looking at the participants’ working environment, job stress, physical fatigue, job satisfaction, and turnover intention, the average score of working environment was 3.16±0.50 out of 5, and 'institutional support' among the sub-factors was the lowest at 2.63±0.67. For job stress, the average score was 3.28±0.53 out of 5, and 'risk of infection' was the highest with 3.51±0.79 points. The average score for physical fatigue was 3.01±0.65 out of 5, and in particular, ‘difficulty due to new roles and demands’ scored 3.16±0.68 points, which corresponded to factors with high physical fatigue. The average scores of job satisfaction and turnover intention were 2.84±0.70 and 3.04±0.76 out of 5, respectivley. 3. As a result of examining the differences in the working environment, job stress, physical fatigue, job satisfaction, turnover intention according to the characteristics of the participants, it was found that if they were satisfied with the salary level, they perceived the working environment as good. However, those who categorized their salary level as 'normal' and 'dissatisfaction' were bound to have higher job stress, physical fatigue, and job satisfaction. Turnover intention differed according to which rank they belonged to; ‘employees and managers’ had higher turnover intention than ‘chief’ and ‘agent level or higher,’ while ‘discontent’ had higher turnover intention than ‘satisfaction’ and ‘normal’ in monthly salary level. 4. As a result of analyzing the correlation between the participants’ working environment, job stress, physical fatigue, job satisfaction, turnover intention, the turnover intention had a negative correlation with the working environment (r=-.63, p<.001) and job satisfaction (r=-.58, p<.001), and positive correlation with job stress (r= .30, p<.001) and physical fatigue (r= .49, p<.001). 5. As a result of hierarchical regression analysis to find out the effect of the subject's work environment, job stress, physical fatigue, and job satisfaction on turnover intention, the variable that had a significant effect on turnover intention was physical fatigue (ß=.31. p<.001), dissatisfaction with salary level (ß=.26, p<.001), working environment (ß=-.24, p=.003), job satisfaction (ß=-.23, p=.001) in order. In other words, the higher the physical fatigue, the higher the dissatisfaction with the salary level, the worse the working environment, and the lower the job satisfaction, the higher the turnover intention. The total explanatory power of these variables explaining turnover intention was 60.9% (F=22.46, p<.001, R2=.609, Adj-R2=.582). Conclusion: In this study, the factors affecting the turnover intention of the administrative staff of small and medium hospitals in the context of COVID-19 in this study were physical fatigue, satisfaction with salary level, working environment, and job satisfaction. The increased workload of hospital administrative staff concerning COVID-19 patients increases physical fatigue, which is expected to increase turnover intention. In addition, dissatisfaction with salary level, working environment, and the job was found to be a factor that increased turnover intention. Therefore, it is necessary to change administrative staff’s salary level and compensation system in small and medium-sized hospitals.

Objectives: The purpose of this study is to explore the degree of empathic abilities, communication competence and their attitudes toward the disabled and identify the relationships among them in female dental hygiene students. Methods: The set of data used in this study were collected from September 2–11, 2020 by means of a self-administered questionnaire. A total of 190 female students in their second and third year of study at the dental hygiene department of a university located in the Gyeongsangnam-do province in South Korea participated in the study. The questionnaire comprised nine questions on general characteristics, 30 on empathic abilities, 15 on communication competence, and 41 on attitudes toward the disabled. The measurement scales used in this study were the Interpersonal Reactivity Index (IRI) for empathic abilities, the Interpersonal Communication Competence Scale (GICC) for communication competence, and the Disability Factor Scale (DFS) for attitudes toward the disabled. Except for the participants’ general characteristics, all the variables were measured on a Likert scale. Means and standard deviations were used to analyze the students’ general characteristics, empathic abilities, communication competence, and attitudes toward the disabled. The differences in the participants’ abilities and attitudes were analyzed according to their general characteristics using an ANOVA and t-test. In addition, the Pearson correlation coefficient was applied to analyze and explore any possible links between the participants’ empathic abilities, communication competence, and attitudes. To explore the factors that influence participants’ attitudes toward the disabled, a multiple linear regression analysis was conducted. Students’ attitudes toward the disabled were considered the dependent variable, whereas the independent variables included the participants’ satisfaction in their major, perspective-taking abilities, imagination, interest in empathy, personal distress, and communication competence. The variables included in the analysis were sub-elements of empathic abilities and had a p < 0.3 in the univariate analysis. Results: The data were analyzed with the 21st edition of the Statistical Package for the SPSS software. The participants’ score was 3.63 points for empathic abilities, 3.69 points for communication competence, and 3.54 points for attitudes toward the disabled. The analyses further indicated a significant positive correlation between empathic abilities and attitudes toward the disabled. With regard to the sub-elements of empathic abilities, the participants’ attitudes toward the disabled had a significant positive correlation with the scales measuring their perspective-taking abilities and their personal distress (p<.05). Furthermore, the analyses indicated a noteworthy positive correlation (p<.05) between communication competence and attitudes toward the disabled. In addition, multiple linear regression analyses confirmed that the students’ attitudes toward the disabled were significantly influenced by the scale measuring their perspective-taking abilities (B=.210). In other words, students with a higher perspective-taking ability displayed a more positive attitudes toward the disabled. Conclusion: This study suggests that the ability of female students in dental hygiene to take perspective, which is associated with empathic abilities, positively influences their attitudes toward the disabled. In turn, a positive attitudes toward the disabled can contribute to improving the quality of their medical services. It is, therefore, crucial to explore ways in which the empathic abilities of those working with the disabled can be improved.

이 연구는 초등학교 5·6학년을 대상으로 비만도를 측정하고 비만도, 신체상, 자아존중감, 그리고 학교생활적응과의 연관성을 규명하고자 수행되었다. 연구 대상자는 경상남도 J시에 소재하는 두 개 초등학교 학생 458명으로 A 초등학교 6학년 전체 학생 200명, B 초등학교 5학년 전체 학생 128명과 6학년 전체 학생 130명이었다. 비만도는 한국소아발육표준치(2007) 중 신장별 체중의 50 백분위수를 표준체중으로 하여 신체발달상황검사에서 측정된 키와 몸무게로 산출하였다. 신체상, 자아존중감, 그리고 학교생활적응은 여러 연구에서 타당성이 검증된 설문 도구를 사용하여 자기기입식의 구조화된 설문지로 측정하였다. 자료수집 기간은 2014년 3월 31일부터 4월 28일이었다. 비만 정도는 남자는 저체중이 25.0%, 정상이 44.6%, 과체중이 15.4%, 경도비만이 9.2%, 중등도 비만이 4.6%, 고도비만이 1.3%였다. 여자는 저체중이 31.2%, 정상이 45.4%, 과체중이 8.7%, 경도비만이 7.8%, 중등도 비만이 6.4%, 고도비만이 0.5%였다. 성별로 유의한 차이는 없었다. 신체상 점수는 남자보다 여자에서 유의하게 낮았으나, 학교별, 학년별, 가족구성, 아버지 교육수준, 어머니 직업종류에 따라서는 유의한 차이는 없었다. 자아존중감 점수는 아버지의 교육 수준이 높은 경우 유의하게 높았으나, 성별, 학교별, 학년별, 가족구성, 어머니 직업종류에 따라서는 유의한 차이는 없었다. 학교생활적응 점수 역시 아버지의 교육 수준이 높은 경우 유의하게 높았으나, 성별, 학교별, 학년별, 가족구성, 어머니 직업종류에 따라서는 유의한 차이는 없었다. 비만도는 신체상과 유의한 부적인 상관(r=-0.493)이 있었으나, 자아존중감 및 학교생활적응과는 약한 부적인 상관(각각 r=-0.060, r=-0.068)이 있었으나 유의하지 않았다. 신체상은 자아존중감 및 학교생활적응과는 유의한 정적인 상관(각각 r=0.529, r=0.303)이 있었다. 자아존중감은 학교생활적응과 유의한 정적인 상관(r=0.734)이 비교적 높게 있었다. 다변량선형회귀형분석에서 학년, 성별, 가족구성, 아버지 교육수준, 그리고 어머니 직업종류를 통제했을 때 비만도와 신체상은 학교생활적응과 정적인 관계(각각 beta=0.129, beta=0.389)가 유의하였다. 결론적으로 비만도는 신체상에 부정적 영향을 미치며, 비만도와 신체상은 다른 조건이 같다면 각각 학교생활적응에 긍정적인 영향을 미치는 것으로 보인다. 그러나 이러한 관계에서 인과성을 확립하기 위해서는 더 많은 연구가 필요하다. Objective: The objective of this study was to measure obesity index and identify the influence of obesity index on body image, self-esteem, and school adjustment in elementary schoolchildren. Methods: The study subjects were 458 children in 5th or 6th grade in two elementary school at J city in Gyeongsangnam-Do. Obesity index was calculated using an individual's weight and height with standard weight based on Korean Child Growth Standards(2007). Body image, self-esteem, and school adjustment were measured with self-administered questionnaires validated in previous studies. The data were collected from 31 March through 28 April in 2014. Results: In boys, 25.0% were underweight, 44.6% were normal, 15.4% were overweight, 9.2% were mildly obese, 4.6% were moderately obese, and 1.3% were severely obese. In girls, 31.2% were underweight, 45.4% were normal, 8.7% were overweight, 7.8% were mildly obese, 6.4% were moderately obese, and 0.5% were severely obese. The difference was not significant between gender. Body image score was significantly lower in girls than in boys. School, grade, family composition, father's educational level, and mother's job made no significant difference in body image score. Except of father's educational level, other socio-demographic factors made no significant difference in self-esteem and school adjustment scores. Obesity index had significant negative correlation with body image(r=-0.493), whereas negative correlations of obesity index with self-esteem(r=-0.060) and school adjustment(r=-0.068) were not significant. Body image had significant positive correlations with self-esteem(r=0.529) and school adjustment(r=0.303). Self-esteem had significant positive correlation with school adjustment(r=0.734). In multiple linear regression analysis, obesity index(beta=0.129) and body image(beta=0.389) had significant influences on school adjustment controlling for socio-demographic factors. Conclusion: Obesity index had negative influence on body image. Both obesity index and body image had positive influence on school adjustment. However, more studies are warranted to establish causality between them. Key words: Obesity index, Body image, Self-esteem, School adjustment, Elementary

본 연구는 치과위생사의 감정노동, 직무스트레스 및 재직의도를 파악하고 감정 노동, 직무스트레스, 재직의도의 관계를 파악하기 위한 것으로 서술적 조사 연구이다. 자료수집 기간은 2015년 9월 14일부터 9월 25일까지 12일간이었으며 연구대상자는 200명 이었다. 자료분석은 SPSS 21.0 프로그램을 이용하여 실수와 백분율, 평균과 표준편차, 독립표본 t-test, Scheffé's test, Pearson's correlation coefficients로 검증 하였고, 단계선택법을 이용한 다중회귀분석을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 1. 감정노동정도의 전체 평균은 5점 만점에 3.20±0.57점 이었고, 직무스트레스의 전체 평균은 4점 만점에 2.39±0.31점, 재직의도의 평균은 8점 만점에 4.89±1.59점이었다. 2. 연구대상자의 일반적 특성에 따른 감정노동의 차이는 연령(F=5.502, p=.005), 근무경력(F=3.034, p=.030), 이직경험(t=2.742, p=.007), 업무량정도(F=11.559, p=.000)에서 차이를 보였다. 3. 연구대상자의 일반적 특성에 따른 직무스트레스의 차이는 최종학력(t=-2.154, p=.032), 업무량(F=20.421, p=.000)에서 차이를 보였다. 4. 연구 대상자의 일반적 특성에 따른 재직의도의 차이는 연령(F=4.666, p=.010), 근무경력(F=4.465, p=.005), 월수입(F=3.321, p=.021), 업무량(F=20.564, p=.000)에서 차이를 보였다. 5.상관분석결과 재직의도는 감정노동정도(r=-.202, p=.004)과 부적상관이 있었으며, 직무스트레스(r=-.479, p=.000)와도 부적상관이 있었다. 감정노동정도와 직무스트레스 간에는 정적상관(r=.404, p=.000)이 있었다. 6. 재직의도에 가장 큰 영향을 미치는 변인은 ‘직무스트레스’(β=-.386) 이었으며, 다음으로 ‘업무량-적당함’(β=.222), ‘소득-250만원 이상’(β=.221), 근무경력(β=-.151) 순으로 영향을 미치는 것으로 나타났다. 직무스트레스, 업무량, 소득, 근무경력 등 4개의 변수에 의한 설명력은 31.4% 이었다(F=22.337, p=.000, R2=.314). This study was conducted to identify relationships among emotional labor, job stress, and intentions to stay among dental hygienists and to grasp the relations among these factors. Data were collected from 200 dental hygienists. Data analysis was conducted using, t-test, ANOVA, and Pearson's correlation coefficients, stepwise multiple regression analysis with SPSS 21.0 program. The result of this study can be summarized as follows: 1. The total average of the emotional labor extent was 3.20±0.57 out of 5 points; that of job stress was 2.39±0.31 out of 4 points; and that of intentions to hold office was 4.89±1.59 out of 8 points. 2. As for the difference in emotional labor depending on the general characteristics of study objects, the significant factors include age (F=5.502, p=.005), working experience (F=3.034, p=.030), experience of changing jobs (t=2.742, p=.007), and workload (F=11.559, p=.000). 3. As for the difference in job stress depending on the general characteristics of study objects, the significant factors include the level of schooling (t=-2.154, p=.032) and workload (F=20.421, p=.000). 4. As for the difference in intentions to stay depending on the general characteristics of study objects, the significant factors include age (F=4.666, p=.010), working experience (F=4.465, p=.005), monthly income (F=3.321, p=.021), and workload (F=20.564, p=.000). 5. The correlation analysis results show that intentions to stay had negative correlation with the extent of emotional labor (r=-.202, p=.004) and job stress (r=-.479, p=.000). It turned out that there was static correlation between the extent of emotional labor and job stress (r=.404, p=.000). 6. The factor that most significantly affected intentions to stay was ‘job stress’(β=-.386), and then ‘workload-moderate’(β=.222), ‘income-2.5 million won or higher’(β=.221), and working experience(β=-.151) in the order. The explanation power of the 4 factors - job stress, workload, income, and working experience - was 31.4% (F=22.337, p=.000, R2=.314)
