The objective of this study is to identify factors affecting the job satisfaction of cook(n= 173) employed in school food service and to propose a plan to improve school foodservice quality. The subjects were cook employed by school in Chungchon province, Gwangju area. The average of cook's job satisfaction was 3.06, the rank factor for nature of work(4.25). the co-workers(3.28), the organic environment(3.17), promotion welfare payment(2.31), the physical environment(2.29) shown respectively. The highest satisfaction with nature of work and organic environment was indicated in the areas of the group of higher age, and cooks who received college education showed significantly lower job satisfaction in physical environment. The highest satisfaction for promotion welfare payment, and physical environment shown in the group of higher length of service who receive higher wages. The groups of regular job shown higher result in the nature of work(3.46>2.94), organic environment(3.46>2.94), promotion welfare payment(2.88>1.94) comparing to irregular job. It is necessary to elevate cook's low satisfaction for improving their work efficiency and the quality of elementary school foodservice.

The objectives of this study are first to develop the index of school health promoting behaviors, two, to measure those, third, to analysis the relative importance of factors that effect on school health promoting behaviors. School health promotion indexes were composed of 60 components of six areas which modify the element of health promoting schools are developed by world health organization. The survey data were collected by questionnaires from June to September in 1998. The number of subjects was 294 school nurses. The SAS-PC program was used for the statistical analysis. The major results were as follows: 1. The six areas of school health promoting behaviors are: school health politics (20 components), the school physical environment (17 component), the school social environment (7 component), community relationships (6 component), personal health skills (7 component) and health services (3 component). 2. The mean of total school health promotion indexes was highest at elementary school as 3.46. The order of area was health services, the school physical environment, school health politics, the school social environment, personal health skills, community relationships. 3. The regression model used in this analysis presented significant relationships between school health promoting behaviors and independent variables. The important variable affecting the area of school physical environment was education level of school nurses. The important variable affecting the area of the school social environment and personal health services were the location of school, credential education program. Age or career also were significant variables affect the community relationships and health services. In summary, The health promoting behavior of elementary school was higher than other school. It is mean that have to perform active promoting behavior at middle school and high school. Health service level was highest among areas of school health promoting behaviors. It is mean also that school nurse teachers is interested in activity for other areas to improve of school health. Furthermore, it is necessary to develop the specific program for school health promoting behavior.

School age is the period when forms the most of physical, spiritual and behavioral developmental characteristics. And those are kept for lifetime. Since each of developmental characteristics is created through the interaction with physical environment, the learning space which is children's main playground should be designed as healing environment. Therefor, the purpose of this research is to find the healing environmental elements for learning space that help school children's developmental characteristics. For that, we researched the physical, spiritual and behavioral developmental characteristics of school children. And we found the healing environmental characteristics for learning space along with each developmental characteristics, by the analysis of Herman Hertzberger's elementary schools' classroom environment.

Recently, a wide variety of studies on future learning have appeared owing to rapid advances in information and communication technology (ICT) and increased discussion about core competencies in twenty-first-century learning. These studies, though insufficient in number, cover various fields such as architecture (design of the learning space), education (learning model), and technology (adaptation of mobile devices). However, these studies focus on mainstream students and do not discuss the future situation of inclusive education with regard to both mainstream and students with physical disabilities. Hence, in order to fill this gap, the present study explores the perceptions and ideas held by special education preservice teachers on the future learning space with regard to school design and peer-to-peer feedback. For this purpose, these preservice teachers' design proposals about future school were collected and analyzed. In conclusion, special education preservice teachers perceive the future learning space as an inclusive environment in which smart technology is incorporated. Future learning environment were categorized in terms of flexible, ubiquitous technology, physical and mental health, safety, and spaces with facilities for students with physical disabilities.

This study sought to describe the relationships among physical environment, self-congruity, positive emotion, and revisit intentions in the coffeehouse setting. This study adopted second-order factor of physical environment in a structural equation model, imploying trend(fashion), cleanliness, reliability, spatial, convenience, and appropriacy as the second-order factors. The conceptual model in this study used responses from 338 college students who visited coffeehouse at least once in the past month. The proposed relationships were analyzed using SPSS 20.0 and AMOS 6.0. The results of data analysis indicated that the six secondorder factors of physical environment significantly affected coffeehouse visitor's self-congruity and positive emotion, and self-congruity as well as positive emotion significantly influenced revisit intentions. Further discussion and theoretical/practical implications of the findings along with directions for future studies are provided. In essence, the findings highlight significant role of coffeehouse's physical environment toward self-congruity and positive emotion in the formation of customer's revisit intentions in the coffeehouse context.

Channel characteristic-based physical layer authentication is one potential identity authentication scheme in wireless communication, such as used in a fog computing environment. While existing channel characteristic-based physical layer authentication schemes may be efficient when deployed in the conventional wireless network environment, they may be less efficient and practical for the industrial wireless communication environment due to the varying requirements. We observe that this is a topic that is understudied, and therefore in this paper, we review the constructions and performance of several commonly used test statistics and analyze their performance in typical industrial wireless networks using simulation experiments. The findings from the simulations show a number of limitations in existing channel characteristic-based physical layer authentication schemes. Therefore, we believe that it is a good idea to combine machine learning and multiple test statistics for identity authentication in future industrial wireless network deployment. Four machine learning methods prove that the scheme significantly improves the authentication accuracy and solves the challenge of choosing a threshold.

PURPOSE: The purpose of this study is to investigate the effect of the physical therapy treatment room environment using microwave diathermy on the autonomic nervous system of human body. METHODS: Participants were 24 healthy adults. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences(RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were compared in microwave irradiation and non-irradiation group. Data were analyzed in Wilcoxon's signed-ranks test and Mann-Whitney U test. RESULTS: Standard deviation of all normal R-R intervals (SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different in microwave irradiation group. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different in microwave non-irradiation group. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different between two groups. CONCLUSION: There was no significant change in the sympathetic nervous system and parasympathetic nervous system regardless of the presence of microwave irradiation. There was no significant change in the autonomic nervous system adaptability regardless of the presence of microwave irradiation.According to this study, microwave diathermy does not have significant effect on the autonomic nervous system.Future study is necessary to investigate the long term effect of the physical therapy treatment room environment using microwave diathermy on the autonomic nervous system of the human body.

The purpose of this study was to compare the anaerobic threshold (AT) between subjects with and without non-specific chronic low back pain (NCLBP). The patient group included 15 women with NCLBP. The normal group included 15 women without NCLBP who were age-, height-, weight-, and activity level-matched. The subjects performed a Balke treadmill protocol which was symptom-limited progressive loading test. Their heart rate (HR), ventilatory gas and metabolic equivalents (METs) were measured using the automatic breath gas analyzing system. After the test, each subjects' ratings of perceived exertion (RPE) were evaluated. The visual analog scale (VAS) was assessed pre- and post-test. The independent t-test and Wilcoxon's signed-rank test were used for analysis of the data. Time, HR, the volume of oxygen consumption ($VO_2$), relative $VO_2$, and METs at the AT level of the patient group were significantly lower than those of the healthy group (p<.05). However, there were no significant differences in RPE, VAS, and breathing frequency at the AT level (p>.05). The findings of this study indicate that patients with NCLBP had a lower aerobic fitness than healthy subjects. Thus, implementation of rehabilitation program to increase aerobic fitness may be considered in patietns with NCLBP, and further studies are required to determine the etiological factors of decreased aerobic fitness.

This study examined the mediating effects of irrational beliefs on the relationships of middle school students' autonomy of psychological growth environment and behavioral anger responses(impulsive reaction, verbal aggression, physical confrontation and indirect expression). A sample of 346 first and second year students of middle school participated in the autonomy of psychological growth environment scale, the irrational beliefs scale and behavioral anger responses scale. Pearson's correlation analysis and regression analysis were performed. The results showed that: ⑴ The relations among autonomy of psychological growth environment, irrational beliefs and behavioral anger responses were significant. The autonomy of psychological growth environment had negative correlations with irrational beliefs and behavioral anger responses. Irrational beliefs produced positive correlations with behavioral anger responses. There were positive correlations among the subtypes of behavioral anger responses. ⑵ There were mediating effects of irrational beliefs between autonomy of psychological growth environment and behavioral anger responses. The effects of autonomy of psychological growth environment on impulsive reaction, physical confrontation and indirect expression were fully mediated by irrational beliefs. However, the effect of autonomy of psychological growth environment on verbal aggression was partially mediated by irrational beliefs. This study demonstrated that irrational beliefs mediate the relationship between autonomy of psychological growth environment and behavioral anger responses.
