  • Background: Occupational accidents occur for a variety of reasons, such as unsafe behaviors of workers and insufficient safety equipment at the workplace, but there are also various economic and social factors that can impact working conditions and working environment. This study analyzed the relationship between changes in economic factors and the occurrence of occupational accidents in Korea. Methods: Multilinear regression analysis was used as the analysis model. The general to specific method was also used, which consecutively removes statistically insignificant variables from a general model that includes dependent variables and lagged variables of dependent variables. Results: The frequency of occupational accidents was found to have a statistically significant relationship to economic indicators. The monthly number of cases of occupational injury and disease and fatal occupational injuries were found to be closely related to manufacturing capacity utilization, differences in the production index in the services sector, and commencements of building construction. The increase in equipment investment indicators was found to reduce fatal occupational injuries. Conclusion: The results of this study may be used to develop occupational accident trends or leading indicators, which in turn can be used by organizations that manage and monitor occupational accidents toward taking administrative action designed to reduce occupational accidents. The results also imply that short-term and mid- to long-term economic and social changes that can impact workers, workplaces and working conditions, and workplace organizations must be taken into account if more effective government policies are to be established and implemented toward further prevention of occupational accidents.

  • This article examined relationships between selected variables, such as demographic background, care, treatment variables, environmental characteristics, and patient's daily behavior and mood change. Relationship were determined between independent variabltherapeutic-rapeutie approach, demographic data, environmental management approach-,and dependent variable-patient's daily behavioral and mood change. 35 patients selected within some criteria in a psychiatric ward, were obserbed during 5 weeks by use of Wyatt's Behavior & Mood Rating Scale ac-cording to the object of the study. At the same time, the frequence of the care and treatment were collected. Criteria for sample selection and independent variables as an influential factor to the patient behavioral change, based on a literature revienw and clinical experiences. Pearson's correlation and multiple regression analysis were used to determine the influfntial factors to the patient behavioral change. Systematic reading (r=.8324), Psychiatrist's individual interview (r=.5764), tranquilizer (r=.3441) and hospitalization processing date (r=.4143) were related with patient's behavioral change. That is these 4 variables can be said to influence to the patient's behavior and mood. A stepwise multiple regression analysis of the effect of the independent varibles of systematic reading, psychintrists individual interview, tranquilizer and hospitalization processing date on the dependent variable, patient's behavioral change was carried out. Systematic reading with on R²of. 69 revealed to be the main influential factor to the patient's behavior and mood change, as the next factor psychiatrist individual interview. A total inclusion of these factors revealed a 73% prediction for the patient's behavior and mood change. But the most influential factor was the interaction of the systematic reading and psychiatrist's individual interview.

  • In this study, certain factors influencing cherry tomato were estimated using system equations. In addition, the amount of influence to income from each factor was estimated from both direct and indirect effects. Based on OLS(Ordinary Least Squares) estimation, path analysis and factor analysis were employed to overcome multicollinearity problems. Data used in this study is interviewed cross sectional data of 65 cherry tomato producing farm in Chungnam-do area. Average age of the producers is 46.5. Average year of the production is 8 years. Average farm size, productivity, and income are 1,123 pyong, 7,439kg/10a, 8,112,000won/10a, respectively. The business performance of the sample farms were above average, in terms of the diagnosis by "Standard Business Diagnosis for Cherry tomato". To identify the factors influencing productivity, 15, 19, and 25 independent variables were selected for the dependent variables of yield, price(quality), and business cost, respectively. Finally, yield, quality, and business cost variables were set as independent variables to explain income as dependent variable. As a result of main factor analysis, 10, 12, 15, and 16 factors were identified as main factors for yield, quality, business cost, and income, respectively.

  • The purpose of this study was to find factors affecting sun protective behavior and intention to buy UV-protective clothing among Korean golfers. Health belief (HB) model and diffusion theory(DT) were used for the study. Dependent variable of HB model was sun protective behaviors (SPBs) and dependent variable of DT model was intention to buy (ITB) UV-protective clothing. Independent variables for HB model were cancer perception, perceived benefits, behavioral/psychological barriers and cues to actions, while independent variables of DT model were relative advantage, compatibility, complexity, friability, and observability, besides demographic variables. Perceived benefits and cues to action variables in addition to gender and age were significant determinants of SPB for Korean golfers. Also, relative advantage and compatibility. behavioral barriers and cues to action were significant in affecting intention to buy UV-protective clothes. Both HB model and extended DT model were useful to predict sun protective behavior of Korean golfers.

  • The purpose of this paper is to estimate consumer's satisfaction by purchasing farmer's processed food. So, this paper surveyed consumers which have purchased Korean traditional soybean paste products, by reason of limiting research objects among lots of farmer's processed food. A survey of 220 consumers was carried out on September and October 2016. For this matters, this paper used multiple linear regression model(included LOG-LIN model) and, set up 1 dependent and 11 independent variables. As the analysis results, we could find out that consumer's satisfaction was affected by 6 variables(price, taste, ease of cooking, confidence of product information, social awareness and perceived 6th industrialization). Among these variables, the strongest variable was "social awareness", and the second was "perceived 6th industrialization". This paper also estimated the rate of change that a dependent variable was affected by independent variables. As the results, this paper found out that "perceived 6th industrialization" had the highest rate of change(5.8%) and the second was "social awareness"(5.6%). This paper proposed 7 implications of Korean traditional soybean paste. Those were the proper price policy and quality value's promotion, quality Improvement and confidence enhancement, development of products for consumer's convenience, enhancement of social awareness, enhancement of politic management about 6th industrialization and accessibility of purchasing information.

  • This research aims to shed light on the technology adoption process and its drivers in the Vietnamese educational system. Research data was collected with an online questionnaire from more than 600 teachers in primary schools, secondary schools, high schools, colleges, and universities in Vietnam in 2020. Based on a holistic literature review, we develop a model of two extrinsic factors (global needs and school-infrastructure), and two intrinsic factors (teachers' technological literacy and their beliefs), which are correlated with the teachers' technological adoption. We measure the dependent variable by asking the teachers' ability and their efficacy to implement technology in teaching according to a Likert scale. With the support of SPSS_22 and STATA_2015, we find that over 70% of changes in technology adoption are explained by the changes in four independent variables and three control variables related to age, gender, and teaching-level of the teachers. Furthermore, these independent variables are significantly and positively associated with two dependent variables. However, a significant difference in technology integration ability can be seen among teachers' gender, age, and school-level. Specifically, male teachers seem to adopt technology at schools than female teachers better, and university teachers have the lowest level of technology adoption compared to other school-level teachers.

  • Objectives: We investigated the operation needs of school meal support centers (SMSC) in Chungnam-do based on analysis of nutrition teachers' perception of them. Methods: The Chungnam government established the first SMSC in 2012. Thirteen SMSCs are currently being operated in Chungnam-do. To analyze the results quantitatively, we investigated nutrition teachers opinions regarding the necessity for SMSCs as a dependent variable and derived the independent variables based on the causal relationships with dependent variables using the ordered logit model. Those independent variables included region, school type, number of students, attitude regarding free meal policy, satisfaction with school meal policy, and preference for local food. Results: Briefly, teachers in the region in which the SMSC was located more strongly supported the SMSC. In addition, teachers in public schools with a smaller number of students believed that having a SMSC is more beneficial, and that other variables also affected the necessity for SMSCs. Moreover, nutrition teachers preferred local foods rather than organic foods because of the unstable supply of organic foods. Conclusions: Based on the results of this study, it was recommended that the local government implement the policy consistently. Moreover, it was recommended that the government operate the SMSC more efficiently, enhance the roles of the SMSC as the local organization responsible for student nutritional planing and expand the coverage of agricultural products.

  • This paper presents the differences in growth of time-dependent strain values in reinforced cement concrete (RCC) and pre-stressed concrete (PSC) flexural members through experiment. It was observed that at any particular age, the time-dependent strain values were less in RCC beams than in PSC beams of identical size and grade of concrete. Variables considered in the study were percentage area of reinforcement, span of members for RCC beams and eccentricity of applied pre-stress force for PSC beams. In RCC beams the time-dependent strain values increases with reduction in percentage area of reinforcement and in PSC beams eccentricity directly influences the growth of time-dependent strain. With increase in age, a non-uniform strain develops across the depth of beams which influence the growth of concave curvature in RCC beams and convex curvature in PSC beams. The experimentally obtained strain values were compared with predicted strain values of similar size and grade of plane concrete (PC) beam using ACI 318 Model Code and found more than RCC beams but less than PSC beams.

  • Objective: The aim of the study is to evaluate the difference of legibility between e-book and paper-book by using eye-tracker. Background: Despite of many researches on the e-book and paper-book, there are few researches on the difference between e-book and paper-book. In addition, the researches on the e-book were only dependent on the e-book reader. This study focused on the comparison of e-book and paper-book controlled with the same environments. Method: This study was conducted with $2{\times}3$ within-subject design. Independent variables include the types of book (e-book, paper-book) and font sizes (8pt, 10pt, 12pt). Dependent variables are four measures of fixation duration, saccade length, blink rate and subjective discomfort. Analysis of Variance (ANOVA) with repeated measured design was used to investigate the main and interaction effects of independent variables on each of the dependent variables. The multiple comparisons were performed by post hoc analysis and Bonferroni correction was applied. Results: Fixation duration at e-book was longer than paper-book (p<0.01). Saccade length at e-book was shorter than paper-book (p<0.05). Blink rate at e-book was higher than paper-book (p<0.1). Subjective discomfort at e-book was higher than paper-book (p<0.1). Legibility at 8pt was better than 10pt, 12pt (p<0.01) in fixation duration, saccade length and subjective discomfort. Conclusion: It was found that the legibility at e-book are worse than paper-book from this study. These results indicated that the legibility of e-book was needed to be validated and improved to replace the paper-book. Application: This study suggests improving something related to fixation duration, saccade length, blink rate and subjective discomfort for betterment of e-book.

  • The purpose of this study is analysis of the relationship between autonomy and group cohesiveness perceived by nurses and their job satisfaction, organizational commitment, motivation and intend to stay on jobs to develope the nursing staff management. The results are as follows: 1. Characteristics of subjects are not significantly different in perceived autonomy, but group cohesiveness, organizational commitment and intend to stay on jobs are different in nursing unit(p<.05). Educational background is significantly different in job satisfaction: nurses who has diploma show higher scores than who has baccalaureate degree(p<.05). 2. Perceived autonomy is related with job satisfaction, motivation and intend to stay on jobs but is not related with organizational commitment(p<.05). 3. Group cohesiveness perceived by nurses is significantly related with job satisfaction, organizational commitment motivation and intend to stay on jobs and their correlation coefficients are higher than that of perceived autonomy(p<.05). 4. The interaction effect of autonomy and group cohesiveness with all dependent variables is not significant(p>.05). The main effect on all dependent variables is presented as group cohesiveness. 5. The canonical correlation coefficient of independent variables and dependent variables is 0.503(p<0.000). The above results are important in the aspect of the development of strateges for retension of qualified nurses performing quality of nursing care and organizational efficacy. Autonomy and group cohesiveness perceived by nurses are important factors in nursing staff management; the further studys on job redesign and intervention strateges for enhancing group cohesiveness are needed.
