  • Objectives: This study aimed to evaluate job satisfaction and its related factors among radiological technologists. Methods: The subjects were 302 persons in various hospitals and the data were collected from 22 May to 17 July, 2005 using a structured questionnaire. It was composed of socio-demographic characteristics, job-related factors, and job satisfaction with the duty inner factors, the duty outside factors, and the organizational factors. Results: Men were more satisfied than women in their employment(p<0.05). Job satisfaction level of university hospital workers were higher than the general hospital, the hospital, and medical clinics. Job satisfaction level of the general radiological technologists showed lower than the chief radiological technologists (p<0.05). In monthly average grant, the more gained, the higher the satisfaction level(p<0.05). By multiple linear regression analysis, the related factors of job satisfaction level were medical field and duty position (p<0.05). Conclusions: The research shows that job satisfactions levels of the radiological technologists are determined by the health and safety of the work environment. Therefore more improvements must be made for radiological technologists to be more satisfied in their jobs.

  • Objectives: The objective of this study was to examine whether dietary quality varies among different age groups and geographic areas, and whether the difference between geographic areas varies across several age groups in Korea. Methods: The subjects were 14,170 subjects who participated in the 2013-2015 Korea National Health and Nutrition Examination Survey. The dietary quality was assessed using the Korean Health Eating Index (KHEI). Age groups were categorized into six groupings, and areas were categorized into urban and rural according to their administrative districts. The effect of area on the KHEI score was analyzed by multiple linear regression analysis. Results: The KHEI was the lowest in the 20-30s group (57.7 ± 0.4 score for 20s and 61.2 ± 0.3 score for 30s) and increased with age (p<0.001), showing the highest score in the 60s (67.9 ± 0.3 score), and then decreased again in the 70s and older (64.6 ± 0.3 score). As a result of comparing the KHEI score by area, the urban areas had higher KHEI scores than did the rural areas (63.5 ± 0.2 score for urban area and 62.2 ± 0.4 score for rural area, p=0.002). The difference between areas was dependent on the age group, showing a significant difference for subjects who were aged from 50s and older (p=0.002 for 50s, p<0.001 for 60s and p<0.001 for 70s and older). After adjusting for confounding factors, the effect of area on the KHEI score was only shown for those subjects in the over 60 years old group (p=0.035 for 60s and p<0.001 for 70s and older). Conclusions: The dietary quality differed according to the age group and geographic area. The dietary quality was lower for younger people than that for older people, and in rural areas compared to that in urban areas, and especially for older adults. The area factor was a very important factor for the dietary quality.

  • Quantitative structure-activity relationship (QSAR) analysis for recently synthesized imidazole-(benz)azole and imidazole - piperazine derivatives was studied for their anticancer activities against breast (MCF-7) cell lines. The statistically significant 2D-QSAR models ($r^2=0.8901$; $q^2=0.8130$; F test = 36.4635; $r^2$ se = 0.1696; $q^2$ se = 0.12212; pred_$r^2=0.4229$; pred_$r^2$ se = 0.4606 and $r^2=0.8763$; $q^2=0.7617$; F test = 31.8737; $r^2$ se = 0.1951; $q^2$ se = 0.2708; pred_$r^2=0.4386$; pred_$r^2$ se = 0.3950) were developed using molecular design suite (VLifeMDS 4.2). The study was performed with 18 compounds (data set) using random selection and manual selection methods used for the division of the data set into training and test set. Multiple linear regression (MLR) methodology with stepwise (SW) forward-backward variable selection method was used for building the QSAR models. The results of the 2D-QSAR models were further compared with 3D-QSAR models generated by kNN-MFA, (k-Nearest Neighbor Molecular Field Analysis) investigating the substitutional requirements for the favorable anticancer activity. The results derived may be useful in further designing novel imidazole-(benz)azole and imidazole-piperazine derivatives against breast (MCF-7) cell lines prior to synthesis.

  • This study was conducted to identify the effects of the degree of death orientation, attitudes toward withdrawing life-sustaining treatment, and awareness of biomedical ethics on paramedic students' own biomedical ethics. The participants of this study were 228 paramedic students from a college located in D city. Data were collected from April to June 2019 through a self-report questionnaire. There was a positive correlation between awareness of biomedical ethics and attitude toward withdrawing life-sustaining treatment (r=.63, p<.001). Multiple linear regression analysis showed that the factors affecting students' awareness of biomedical ethics were religion (β=.12, p=.018) and their attitude toward withdrawal of life-sustaining treatment (β=.61, p<.001), with an explanatory power of 41.0%. Educational programs must focus on attitudes toward withdrawing life-sustaining treatment to improve paramedic students' awareness of biomedical ethics.

  • Purpose: The aim of this study was to investigate the perceptions of nurses regarding their roles in social welfare facilities, including role expectation, role performance, and role conflict and its influencing factors. Methods: Data were collected by administering a structured questionnaire to 92 nurses working in 5 types of social welfare facilities. Descriptive statistics, paired t test, Pearson correlation coefficient, and multiple linear regression analyses were performed using the SPSS Win 18.0 program. Results: The mean score of role expectation ($4.44{\pm}0.41$) was significantly higher(t =17.50, p<.001) than that of role performance ($3.46{\pm}0.005$). The biggest mean difference between role expectation and role performance was found in "research activities" ($2.92{\pm}0.81$). The mean score of role conflict was $2.89{\pm}0.66$, with the highest mean score found in "conflict caused when one nurse takes up two or more roles" ($3.31{\pm}0.69$). The influencing factors on role conflict were the difference between role expectation and role performance(${\beta}=.45$, p<.001), and facility size (${\beta}=-.37$, p<.001), which accounts for 51.5% incidence of role conflict controlling nurses' age, career, position, and working periods in social welfare facilities (F=17.13, p<.001). Conclusion: The nurses working in the social welfare facilities perceived some restrictions on their role performance compared with their role expectation, this difference being a major factor influencing their role conflict. Therefore, future studies need to investigate interventions to minimize this effect.

  • Purpose: This study investigated the current status of post-traumatic stress and related factors among safety managers in Korea National Parks. Methods: The study subjects were 109 safety managers working in Korea National Parks. General characteristics, job-related characteristics, experience of traumatic events and post-traumatic stress were collected by self-reported questionnaires through the mail. The associated factors with post-traumatic stress was analyzed by t-test, ANOVA and multiple linear regression. Results: Overall score of post-traumatic stress was $10.32{\pm}11.37$ and 12.8% was the high-risk group of post-traumatic stress disorder. In simple analysis, score of post-traumatic stress was associated with drinking frequency, disease history, duration of career, delay of rescue, provided the break, rest space and the number of experiences of traumatic events. Finally, the score of post-traumatic stress was significantly higher in subjects who experienced 3 (B=9.141, SE=3.538) or more than 4 (B=11.367, SE=3.063) traumatic events compared to subjects without experience of traumatic event. Conclusion: The score of post-traumatic stress was $10.32{\pm}11.37$ and 12.8% was the high-risk group among safety managers in Korea National Parks. Post-traumatic stress was associated with the experience of traumatic events. Management of safety managers after mobilization or experience of traumatic events will be helpful to decrease of post-traumatic stress.

  • This study was designed to investigate organizational culture and emotional intelligence as predictors of job performance among library personnel in Edo state, Nigeria. The survey research design was employed for the study with a population size of 181 library personnel in the 15 academic libraries under study, and due to the manageable population size, total enumeration was adopted as the sampling technique. The questionnaire was used to elicit data from the respondents. Of the 181 copies of the questionnaire administered, 163 copies were retrieved and found valid for analysis constituting a 90% response rate. Four research questions and four null hypotheses (tested at 0.05 level of significance) were formulated to guide the study. The tool used to analyze the research question was descriptive statistics (percentage, mean, and standard deviation) and inferential statistics (correlation and multiple regression) for testing the hypotheses. The findings of the study revealed that there is a high level of job performance, good organizational culture, and high level of emotional intelligence among the personnel. Organizational culture and emotional intelligence jointly and significantly predict job performance of personnel. There is significant positive correlation between organizational culture and job performance. The linear combination of emotional intelligence and organizational culture predict job performance of library personnel in the academic libraries under study. The research concludes that there is a need for high job performance in libraries which is predicted by the organizational culture of the library and the level of emotional intelligence of the library personnel.

  • This study examined the predisposing, enabling and need factors, based on Andersen's behavioral model, affecting intention to use community organizing services at a community welfare center. 725 people aged 20 and older who lived in Gwang-jin-gu participated in this study and multiple linear regression analyses were utilized to analyze the deputation. The results demonstrate that intention to use is primarily affected by predisposing factors, age and duration of education. Female and more educated people were significantly associated with the intention to use community organizing services. Enabling factors, reputation and image of the community welfare center significantly affect intention to use community organizing services. People are more likely to use community organizing services when there is higher reputation of the community welfare center and better image of the community welfare center. Finally, intention to use is primarily affected by welfare consciousness, a need factor. People who have liberal welfare consciousness are more likely to use community organizing services. These findings provide implications and suggestions for increasing intention to use community organizing services at a community welfare center.
