The objectives of this study were to determine the degree of job satisfaction and need satisfaction of school foodservice employees, and the relationship between Job in General(JIG) and need satisfaction. The six demographic items, the Job Descriptive Index(JDI) and JIG scale, and Need Satisfaction Questionnaire(NSQ) were used to evaluate job satisfaction and need satisfaction of school foodservice employees. The results of this study showed that the employees were satisfied with co-workers(2.52), then supervision(2.48), work(1.86), promotion(0.72) and pay(0.51) in decreasing order. Older employees(Age$\geq$40) tended to be more satisfied in JIG(p＝0.0620) than younger employees(20$\leq$Age$\leq$39). Employees were satisfied in social needs, then autonomy needs, self-actualization needs, esteem needs, security heeds in decreasing order. There were no significant differences between demographic factors and five need categories. When the employees were classified by their scores on JIG, Group I having the lowest score tended to be less satisfied(p＝0.0627) in security needs than Group II and Group III. The information of study could be useful for foodservice managers in job design to increase the productivity.

Today's health care environment is rapidly changing and nurse administrators' transformational leadership needs to practice in nursing organization to achieve organizational objectives. Transformational leadership is related to the job satisfaction, productivity, and organizational commitment. This study investigated the effect of transformational leadership and carreer characterics on nurses' organizational commitment. The sample for this study consisted of 594 nurse from 8 large Korean hospitals. The factor analysis Cronbach's alpha analysis, Pearson correlation analysis, multiple regression analysis and hierarchical multiple regression analysis were used for the statistical method. The results of this study were found that (1) charisma dimension of transformational leadership has positive influence on nurses' organizational commitment; but another two dimensions (intellectual stimulation and individualized consideration) did not showed significant effect on organizational commitment (2) nurses' career characteristic(age, marital status, education level. work duration, status) moderated the effect of transformational leadership on organizational commitment.

The concepts of interior design work have set forward an aesthetic and functional proposition to be answered by those who design spaces. The available range of suitable materials for interior use appears to be almost inexhaustible in this day and age. Now a day, relatively new fields of study on environmental-friendly interior examine humans'innate affinity for health and explore its implications for architecture and the built environment. A growing field of research suggests that spaces' relationship to aesthetics and environment can either help or hinder their occupants' health and wellness, productivity, and even their creativity. This paper presents several examples of already built apartment houses in practice, and discusses the demand of users of the spaces for health and sustainable environment, deepening the relationship between newly-constructed spaces and the remodeled ones. The considerations to some new and contemporary materials from the aspect of healthy indoor architecture design are presented in this paper. Designers need to rethink the conventional and high-tech interior environment in apartment houses with respect to perceived air quality, material emissions, and odors. The future of interior design is oriented on light shapeable materials which are able to create a unique memorable atmosphere. The primary assignment in accepting recent materials and proceedings is our responsibility to creating proposals, that are mainly safe, hygienic and environmentally proper.

Background: Coal mining is of significant economic importance to the Australian economy. Despite this fact, the related workforce is subjected to a number of psychosocial risks and musculoskeletal injury, and various psychological disorders are common among this population group. Because only limited research has been conducted in this population group, we sought to examine the relationship between physical (pain) and psychological (distress) factors, as well as the effects of various demographic, lifestyle, and fatigue indicators on this relationship. Methods: Coal miners (N = 231) participated in a survey of musculoskeletal pain and distress on-site during their work shifts. Participants also provided demographic information (job type, age, experience in the industry, and body mass index) and responded to questions about exercise and sleep quality (on-and off-shift) as well as physical and mental tiredness after work. Results: A total of 177 workers (80.5%) reported experiencing pain in at least one region of their body. The majority of the sample population (61.9%) was classified as having low-level distress, 28.4% had scores indicating mild to moderate distress, and 9.6% had scores indicating high levels of distress. Both number of pain regions and job type (being an operator) significantly predicted distress. Higher distress score was also associated with greater absenteeism in workers who reported lower back pain. In addition, perceived sleep quality during work periods partially mediated the relationship between pain and distress. Conclusion: The study findings support the existence of widespread musculoskeletal pain among the coal-mining workforce, and this pain is associated with increased psychological distress. Operators (truck drivers) and workers reporting poor sleep quality during work periods are most likely to report increased distress, which highlights the importance of supporting the mining workforce for sustained productivity.

Purpose: By empirically analyzing factors that affect the intention to introduce RPA, we aim to increase understanding of RPA introduction in small and medium-sized businesses and contribute to establishing an effective introduction strategy. The aim is to improve the company's productivity, reduce costs, and strengthen its competitiveness. It also provides policy recommendations for the introduction of RPA. Methods: A survey was conducted to examine whether the technical, organizational, and environmental factors of the TOE framework had an impact on the intention to adopt RPA. We also used stepwise regression analysis to determine whether firm size moderates this relationship. Results: Technical factors, organizational factors, and environmental factors were all found to have a significant impact on small and medium-sized enterprises' intention to adopt RPA. It was confirmed that company size has a moderating effect affecting the intention to adopt RPA. In particular, customer pressure, relative advantage, competitive pressure, age, government support, and the perceived ease of use of RPA was a key determinant of its adoption by small and medium-sized enterprises. Conclusion: This suggests that small and medium-sized businesses should comprehensively consider technical, organizational, and environmental factors when introducing RPA. It is expected to increase understanding of RPA introduction in small and medium-sized businesses, contribute to establishing effective introduction strategies, and contribute to improving company productivity, reducing costs, and strengthening competitiveness.

To investigate the causes of Korea's growth slowdown over the past thirty years, we estimate the contributions of major developmental factors, including i) demographic factors (changes in population growth and workforce age due to the demographic transition), ii) quality-of-life-related choice factors (changes in working hours, education, and the female employment rate), iii) structural change, and iv) the effects of productivity catch-up. Our estimates show that these four groups of factors account for approximately 90 percent of the growth slowdown, with demographic factors contributing approximately 30 percent and the other three groups of factors each contributing about 20 percent. We also show that the same factors explain most of Korea's high growth in the 1980s. These results suggest that Korea's growth slowdown is basically a consequence of its successful economic development and that the high growth and subsequent slowdown can be regarded as a single process. In addition, given that the factors examined here exhibit similar patterns of change in the course of economic development of most countries, we think that our estimation results of the relationship between economic development and changes in economic growth trends could have more general implications that go beyond Korea's experience.

The purpose of this study was to derive association between company's fringe benefits and retirement planning. The study analyzed the 2016 Korean Longitudinal Study of Ageing(KLoSA) and a total of 1,740 participants was included. To analyze the relationship between the number of the company's employee fringe benefit and the retirement planning, multiple logistic regression was conducted. As a result, we found multiple variables affecting the retirement planning including not only the number of the fringe benefits, but also the age, marital status, residence, private health insurance status, and subjective health status. Successful retirement planning for wage workers benefits not only the individuals or government, but companies also gain benefits such as improved productivity of workers and a better corporate image, so further research is needed on the effective implementation of the system, and the role of government to support this.

Site index is an essential tool to estimate forest productivity. Generally, a site index equation is developed and used from the relationship between stand age and dominant tree heights. However, there is a limit to the use of the site index equation in the application of variable ages, environmental influence, and estimation of site index for the unstocked forest. Therefore, it has been attempted to develop a new site index equation based on various environmental factors including site, climate, and topographical variables. This study was conducted to develop a site index equation based on the relationship between site index and environmental factors for the species of Pinus koraiensis in Yangpyung-Gun, Gyunggi Province. The influence of climatic factors (temperature and solar irradiation ratio), topographical factors (elevation, slope, ratio of slope to valley and aspect) and soil profiles (soil depth by layer and soil consistency) on site index were evaluated by multiple regression analysis. Five environmental factors were selected in the final site index equation for Pinus koraiensis. The site index equation developed in this study was also verified by three evaluation statistics: model's estimation bias, model's precision, and mean square error of measurement. Based on the site index equation, the number of productive areas for Pinus koraiensis were estimated by applying GIS technique to digitized forest maps. In addition, the distribution of productive areas was compared with the areas of current distribution of Pinus koraiensis. It is expected that the results obtained in this study could provide valuable information about the amount and distribution of productive areas for Pinus koraiensis reforestation.

The aim of this study was to estimate the factors that can be used as a predictive indicator of antler productivity in elk. Body weight and antler data from 115 stags raised at the Animal Genetic Resources Research Center in Korea were used in this study. The function for the average antler weight was derived by age, which was $y=-3.4693+5.3747x-0.8x^2+0.0424x^3$, and $R^2$ was 0.991. The analysis of the relationship between body weight at birth and the 1st and 2nd year and the antler weight after the 2nd year showed a correlation between them. There was a correlation between the antler weight of 1 and 2 year old stags and the weight of 2 year old stags as well; especially, both antler weights for the 1st and 2nd year were highly correlated with the antler weight of the 4th year. However, there was no relationship between the antler main beam length for the 1st and 2nd year and the antler weight after the 3rd year. Therefore, it is expected that a large amount of antler will be obtained in the future if proper management is carried out for young deer from birth to 2 years old. Additionally, the results of this study are expected to be useful for the development of a deer breeding program and the deer industry.

Diarrhea is reported as one of the most common diseases in calves. It is thought to be a major cause of productivity and economic loss to cattle producers. The aim of this study is to provide a better understanding of well-known diarrheagenic pathogens and incidence of diarrhea in Korean calves. In this study, the relationship of calf diarrhea and pathogens were investigated from calves under 60 days of age in five areas of Korea from April to July, 2016. Of examined fecal samples, 38.3% was positive for any pathogens, and Giardia was the most common pathogen (25.5%). The incidence of diarrhea was 31% from pathogen-negative fecal samples whereas 61.1% from pathogen-positive fecal samples, suggesting high correlation between pathogenic factor and diarrhea. In addition, 80% of E. coli (K99) positive calves showed diarrhea, suggesting E. coli (K99) could be highly pathogenic. The incidence of diarrhea and infection rate increased with age. Rotavirus was revealed as a major pathogen in calves under 20 days of age, and the infection rate of Giardia increased rapidly in calves 20 to 39 days of age. The information on interconnections between clinical diarrhea and pathogens would contribute to developing strategies for treatment of calf diarrhea.
