  • The purposes of the study were to assess levels of burnout, engagement, and turnover intention of dietitians and chefs and to investigate the relationships among the antecedents and consequences of burnout and engagement. A total of 257 dietitians and chefs at a contract foodservice management company in Korea were surveyed using a self-administered questionnaire. Burnout (exhaustion, cynicism, and professional efficacy) and engagement (vigor, dedication, and absorption) were measured with three dimensions each. The dietitians showed significantly higher exhaustion (p < .05) and significantly lower vigor and dedication than the chefs (ps < .05). The exhaustion and cynicism dimensions of burnout were negatively correlated with all three dimensions of engagement (ps < .001) and positively correlated with turnover intention (ps < .001). The professional efficacy was positively correlated with all three engagement dimensions (ps < .001), but not with turnover intent. In addition, turnover intention was positively correlated with negative affectivity and work-load and negatively correlated with vigor, dedication, and absorption. A series of hierarchical regression analyses were conducted to assess the effects of the personal (positive and negative affectivity) and situational factors (workload, interpersonal conflict) and job stresses on turnover intention. After removing the effects of the personal and situational factors, cynicism (p < .01) was the only significant predictor of turnover intention. Based on the findings, suggestions for recruiting and retaining qualified and motivated employees were provided.

  • Purpose: This study aimed to evaluate the relationships among quality of life, caregiver depression levels, and disease severity, especially motor function, in children with cerebral palsy. Methods: Data were collected through questionnaires using survey and interview from 80 caregivers of children with cerebral palsy. The caregivers' quality of life was measured using medical outcomes study 36-item short form health survey, and level of depression was scored using the beck depression inventory. In addition, children's motor function was evaluated using gross motor function measure-88 and functional independence measure scores. Results: Among 8 domains of medical outcomes study 36-item short form health survey, "physical functioning," "physical role functioning," "mental health," and "bodily pain" domains were significantly correlated to "total" percentage scores of gross motor function measure-88. In addition, "mental health" and "bodily pain" domains were correlated to each sub-dimension, including "lying and rolling," "sitting," "crawling and kneeling," "standing," and "walking, running, and jumping." Similarly, the "running" and "jumping" dimensions including motor function measures correlated with "transfer," "locomotion," and "motor subtotal" of functional independence measure scores. The beck depression inventory scores were negatively correlated to "lying and rolling," "sitting," "crawling and kneeling," and the "total" percentage scores of gross motor function measure-88. The beck depression inventory scores were negatively correlated to "sphincter control," "communication," "social cognition," "cognitive subtotal," and "total" functional independence measure scores. Conclusion: It is necessary to consider the quality of life and emotional problems of caregivers of CP children and support them both physically and psychologically with comprehensive rehabilitation.

  • The wavelet analysis method is introduced in this paper to study the nonstationary vibration of vehicles. A new road model, a so-called time domain correlated four-wheel road roughness, which considers the coherence relationships between the four wheels of a vehicle, has been newly developed. Based on a vehicle model with eight degrees of freedom, the analysis of nonstationary random vibration responses was carried out in a time domain on a computer. Verification of the simulation results show that the proposed road model is more accurate than previous ones and that the simulated responses are credible enough when compared with some references. Furthermore, by taking wavelet analysis on simulated signals, some substantial rules of vehicle nonstationary vibration, such as the relationship between each vibration level, and how the vibration energy flows on a time-frequency map, beyond those from conventional spectral analysis, were revealed, and these will be of much benefit to vehicle design.

  • This paper investigated the relationships among Korean EFL learners' listening anxiety, listening strategy use, and listening proficiency. One hundred and forty four Korean college students who were enrolled in the required practical English classes participated in this study. Questionnaires related to students' listening strategy use and listening anxiety were administered and a TOEIC listening comprehension test was given to measure the students' listening proficiency. The one-way ANOVA was used to analyze the data. The findings of this study are that the students' listening performance is positively correlated with their strategy use and negatively correlated with their anxiety level, and their strategy use is negatively correlated with their anxiety level. The results suggest that successful learning will occur when anxiety is reduced and when the use of strategies is encouraged more often. The pedagogical implications for EFL educators and teachers are described.

  • The relationships between the cover of herbaceous species and 15 soil chemical properties (organic carbon contents, total N, available P, exchangeable K, Na, Ca and Mg, HCl-extractable Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in nine poorly controlled waste landfill sites in Korea were examined by correlation analysis and multiple regression equations. Species showed different patterns of correlation between their cover values and soil chemical properties. The cover of Ambrosia artemisiifolia var. elatior, Aster subulatus var. sandwicensis and Erechtites hieracifolia were negatively correlated with the contents of Fe, Mn and Ni within landfill soils. Total cover of all species in quadrats was positively correlated with the contents of Cd and negatively correlated with the contents of Mn and Fe from stepwise regression analysis with 15 soil properties. Canonical correspondence analysis demonstrated that the distribution of native and exotic plants on poorly controlled landfills was significantly influenced by the contents of Na and Ca in soils, respectively.

  • Purpose: This study examined how interpersonal relationship abilities in the elderly affected anger control abilities, as well as the mediating effects of generativity in the relationships between interpersonal relationships, anger control abilities, and self-integration. Research design, data and methodology: The study consisted of randomly selected 300 elderly people currently residing in welfare centers for the elderly, senior citizens colleges, social welfare facilities and other centers in the Seoul or Gyeonggi area. SPSS 23.0 was utilized for this study. Results: Through this research, the effect of interpersonal relationships on anger control ability and self-integration was observed. Not only that, the effects of interpersonal relationship abilities on anger control and self-integration and the mediating role of generativity, was also closely examined. Conclusion: Anger control ability was found to have a direct positive effect on interpersonal relationship abilities. Anger control ability had a direct and positively correlated effect on self-integration. Additionally, ability to control anger was found to have a positive effect on generativity, and generativity was found to have a positive effect on interpersonal relationship ability, but it was not statistically significant. Anger control ability had a positive effect on generativity, and generativity had a positive effect on self-integration.
