Rapid economic growth brought material affluence and convenience, but it also has caused a negative issue, such as environmental damage. Therefore, this research holds the purpose of grasping structural influencing relationship of environmental awareness of cook, which is taking an important role in food safety among workers in hotel restaurants with eco-friendly attitude and food safety pursuit behavior. To achieve the purpose, collected materials were tested for the fidelity, organic causation and control effect, using Structural Equation Modeling for frequency analysis, confirmatory factor analysis, credibility analysis and hypothesis testing with SPSS (V23.0) and AMOS (V21.0) programs. Environmental awareness of hotel cook has causation with eco-friendly attitude, and the attitude has meaningful causation with food safety pursuit behavior. That is, it proved that cooks are taking care of their job carefully from the pre-cooking stage while most of people ignore the storing stage. The result shows not only hotel's own training session, cook's level of consciousness on the food safety and they are working with high sense of responsibility. The limitation of this research is that it only conducted with cooks of deluxe hotels in Busan, and it could not include various variables about environmental awareness. Therefore, it is expected that the lacking contents to be dealt by a follow-up study.

Plant stress incurred by flooding was studied in terms of oxidative stress, using greened rice seedlings subjected to a complete submergence followed by re-exposure to air under illumination ($30W/m^2$). It appeared that shoot tissues of the seedlings suffered oxygen deficiency during the flooding treatment, pertinent to the general concept. Interestingly enough, however, membrane peroxidation in shoots was enhanced by the submergence, as assessed by the content of 2-thiobarbituric acid-reactive substances (TBARS), and the re-aeration resulted in a rapid reduction of TBARS content. Such pattern of response was also seen in the change in the steady state level of $H_2O_2$. In contrast, superoxide dismutase and glutathione reductase that are involved in the detoxifying processes of superoxide in plant cells were significantly activated only during the re-aeration. These results allowed us to suggest the followings as a working hypothesis. Photorespiration-linked production of $H_2O_2$ may largely contribute to the increase in $H_2O_2$ level as well as TBARS production in shoots during the submergence. An abrupt re-supply of $CO_2$ by the re-aeration brings the photosynthetic apparatus back to full operation, suppressing photorespiration and probably causing a momentary, excess formation of superoxide and its dismutation product through side reaction, which gives rise to activating substrate-inducible antioxidative enzymes.

This study is intended to look into the structural relationships between project manager's creative thinking, entrepreneurship, and project performance. To achieve this, research model and hypothesis were established to carry out statistical analysis based on the results of an empirical sample survey. The findings showed that project manager's creative thinking didn't improve project satisfaction directly, but it improved project satisfaction through the mediating effects of project manager's entrepreneurship. While it had a direct effect on perceived project performance, project manager's entrepreneurship was not mediated in this process. This suggests that even if project managers have a high expertise, thinking skill and motivation as creative thinking in working on the project, they have the limitation in leading to customer satisfaction from a personal perspective.

Learning disorders are diagnosed when the individual's achievement on standardized tests in reading, mathematics, or written expression is substantially below that expected for age, schooling, and level of intelligence. Subtypes of learning disorders may be classified into two groups, language-based type learning disorders including reading and writing disorder, and nonverbal type learning disorder (NLD) such as those relating to mathematics & visuospatial skills, and those in the autism spectrum. Converging evidence indicates that reading disorder represents a disorder within the language system and more specifically within a particular subcomponent of that system, phonological processing. Recent advances in neuroimaging technology, particularly the development of fMRI, provide evidences of a neurobiological basis for reading disorder, specifically a disruption of two left hemisphere posterior brain systems, one parieto-temporal, the other occipito-temporal. The former is the reading system for beginner reading, the latter for skilled reading. Compensatory engagement of anterior systems around the inferior frontal gyrus(Broca's area) and a posterior(right occipito-temporal) system is noted in persistent poor readers in long-term follow up study. The theoretical model proposed to explain NLD's source is not right hemisphere damage, but rather the white matter model. The working hypothesis of the white matter model is that the underdevelopment of, damage to, or dysfunction of cerebral white matter(long myelinated fibers) is the source of this disorder. The role of an evidence-based effective intervention in the remediation of children with learning disorder is discussed.

The aim of this study is to explore the effect of injustice perception on work alienation and the mediating role played by the employee's cynicism between injustice perception and work alienation in the healthcare sector in Oman. By utilizing a simple random sampling technique, data were collected using a questionnaire consisting of 306 nurses working in private healthcare providing organizations in Oman. The collected data was then analyzed using AMOS program through the Structural Equation Modeling (SEM). The results of study show that the levels of perception of injustice and cynicism of nurses in the private healthcare centers were low, while the work alienation was found to be at moderate level in these healthcare organizations. The findings of the empirical study reveal that injustice perception and employee's cynicism significantly affect work alienation. The impact of injustice perception in creating employee's cynicism was also observed. The hypothesis that the mediating role played by employee's cynicism in injustice perception and work alienation relationship was partially supported. Moreover, injustice perception and cynicism directly affect work alienation, therefore, these hospitals should consider organizational policies and procedures to achieve equality and justice among nursing personnel, and to eliminate the factors that cause cynicism and work alienation.

The purpose of this study is to scrutinize the effect of office layouts and ambient office sounds on the performance of office workers involved with a proof-reading test (simple task). Twenty subjects, who were professional researchers and computer programmers, were from three different office layouts: 1) Nine subjects from a combined office type with open meeting places and closed individual offices; 2) five from an open office with rectangular individual workstations, and 3) six from an open office with triangular individual workstations. Architects and consultants working in the field of office have reported from interviews and their own observations that occupants' satisfaction differs as their office layouts vary although the sizes are the same. This finding leads to the hypothesis of this experiment. Proof-reading test results were obtained from three different office layouts (combined office type, rectangular and triangular individual workstations in open offices) under two different sound conditions (quiet background sound and ambient sound of their own workplace) for 10 minutes. The test analysis shows the mean test score of subjects from the triangular individual workstations in open offices is significantly different from the mean test scores of subjects from the combined office type and the rectangular individual workstations in open offices.

It requires to make the safety education not a merely formal education but as a practical one for the factor of safety on the industrial environment. We surveyed the workers who are working for a power plant-related small and medium sized businesses around Incheon about the necessity of safety education to improve the safety awareness for themselves. The answered workers for the survey are numbered 198, and we can analyzed those questionnaires by using SEM(Structural Equation Modeling). We ran the analysis by the tool of statistics, AMOS19.0. We examined the basic hypothesis that self-efficacy, safety education, and perceived safety influenced on the will for the safety on the job through the attitude of safety on the work as a parametric cause. We can derive a result that self-efficacy and education about safety makes an effect not only on the will for the safety directly, but also through the attitude and perceived safety. Perceived safety does not influenced on the attitude of safety on the work. Education, attitude, and perceived safety show positive influential factors, but self-efficacy represents negative effect directly on the will for the safety. Safety eduction makes more positive effect on the attitude and perception of the safety, and it shows the necessity for the reinforcement.
