  • As a part of attempts to understand better mathematics classroom culture, this paper first reviews plausible factors which influence the mathematics teacher's own development of instructional goals. The proposed factors consist of teacher characteristics and sociocultural factors. The teacher factors include learning and teaching experience, knowledge, beliefs, and personality traits. The sociocultural factors include cultural and educational norms, curriculum development and administration, teacher education, and professional models with community, This paper then presents detailed interview questions to explore significant influences on the teacher's conceptions of mathematics and its teaching. The interview probes 12 topic areas: (a) early influences on becoming a teacher, (b) the decision to become a teacher, (c) the teacher education years, (d) early mathematics interests, (e) early teaching experiences, (f) career path, (g) influence of peers within the school, (h) influence of administrators, (i) professional development, (j) professional self-development, (k) mathematics teaching, and (i) educational policies.

  • The reliability of power system components can be affected by a numbers of factors such as the health level of components, external environment and operation environment of power systems. These factors also affect the electrical parameters of power system components for example the thermal capacity of a transmission element. The relationship of component reliability and power system is, therefore, a complex nonlinear function related to the above-mentioned factors. Traditional approaches for reliability assessment of power systems do not take the influence of these factors into account. The assessment results could not, therefore, reflect the short-term trend of the system reliability performance considering the influence of the key factors and provide the system dispatchers with enough information to make decent operational decisions. This paper discusses some of these important operational issues from the perspective of power system reliability. The discussions include operational reliability of power systems, reliability influence models for main performance parameters of components, time-varying reliability models of components, and a reliability assessment algorithm for power system operations considering the time-varying characteristic of various parameters. The significance of these discussions and applications of the proposed techniques are illustrated by case study results using the IEEE-RTS.

  • Atopic disease is caused by a complex combination of environmental factors and genetic factors, and studies on influence of exposure to various environmental factors on atopic diseases are continuously reported. However, the exact cause of atopic dermatitis is not yet known. Our study was conducted to analyse the association of SNPs with the development of atopic disease in a small cohort. Samples were collected from the Mothers' and Children's Environmental Health (MOCEH) study and 192 cord blood DNA samples were used to identify incidence of atopy due to influence of exposure to environmental factors. Genetic elements were analysed using a precision medicine research (PMR) array designed with various SNPs for personalized medicine. Case-control analysis of atopy disease revealed 253 significant variants (p<0.0001) and SNPs on five genes (CARD11, ZNF365, KIF3A, DMRTA1, and SFMBT1) were variants identified in previous atopic studies. These results are important to confirm the genetic mutation that may lead to the onset of foetal atopy due to maternal exposure to harmful environmental factors. Our results also suggest that a small-scale genome-wide association analysis is beneficial to confirm specific variants as direct factors in the development of atopy.

  • The study investigates some psychological and environmental factors affecting the intention to purchase organic foods of consumers in the inner-city of Hanoi. Impact factors applied for the study include three psychological factors (health concern, environmental concern, consumer awareness of organic foods) and seven environment factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, social status, mass media, state's encouragement). We analyzed research data from 396 consumers to measure the impacting level of these factors. The convenient sampling method was used to collect the research sample. The measurement applied a 5-point Likert scale classifying from 1-completely disagree to 5-completely agree. Based on previous studies, the research model was recommended. We had estimated the reliability of the scales through Cronbach's Alpha and composite reliability. The research data is analyzed by using Structural Equation Model method (SEM). The findings of the study suggest that psychological factors (health concern, environmental concern, consumer awareness of organic foods) had a significantly positive influence on consumer's purchase attention toward organic food. The results also revealed that environmental factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, mass media) were positively linked to consumer's purchase attention toward organic food.

In addition, the characteristics of the center organization were examined to provide practical guidelines for the operation of the center. The aim was to determine management implications with an important meaning in human resource management to enhance the efficiency of the operation of Centers for Children's Foodservice Management (CCFSM). Methods: Out of 207 centers, there were 1,057 employees at 173 centers who agreed to participate in the study, the questionnaire was mailed on February 17, 2017 and collected by mail on March 31, 2017. Finally, 81 centers (46.82%) participated in the survey and 493 questionnaires were used. Results: Neuroticism among the five personality factors had a positive (+) influence on 'cynicism' and 'exhaustion' among the three subordinate factors of emotional exhaustion, negative (-) effects on the 'job' among the six subscales of job satisfaction. In addition, openness showed a negative (-) effect on 'loss of professional confidence' of emotional exhaustion and positive (+) relationship with the 'job' of job satisfaction. Agreeableness appeared to have a negative (-) effect on all factors of emotional exhaustion and a positive (+) influence on all factors of job satisfaction. As a result of analyzing the effects of job performance on emotional exhaustion and job satisfaction, the planning and operations management team showed a positive (+) influence on all factors of emotional exhaustion and negative (-) influence on all factors of job satisfaction. On the other hand, the nutrition management team showed a negative (-) influence on all emotional exhaustion factors and a positive (+) influence on the factors of job satisfaction. The hygiene management team showed a positive (+) relationship with 'Emotional exhaustion' among the subordinate factors of emotional exhaustion and a negative (-) influence on the 'Educational opportunity' of job satisfaction. Conclusions: The personality type and job performance of Centers for Children's foodservice management (ccfsm) staff significantly affected the emotional exhaustion and job satisfaction.

  • This study analyzed the factors influencing the technology acceptance of the general public in the drones and ARs, one of the key technologies of the industry 4.0. The theoretical basis was the extended unified theory of acceptance and use of technology model(UTAUT2), which uses performance expectancy, effort expectancy, social influence, facilitating conditions, and hedonic motivation as factors common to both services. The price value factor was excluded considering that most ARs were free, and the perceived risk factors, including privacy, which were not in UTAUT2, were included because they are important factors for ICT technology acceptance. The hypothesis was tested by structure equation model. Social influence and hedonic motivation had a positive(+) effect on intention to use technology. On the other hand, in the case of effort expectancy, neither the AR nor the drone had a significant influence on intention to use technology. Furthermore, performance expectancy had a positive(+) effect on intention to use in AR, but no significant influence was found out in drones. On the contrary, in the case of the facilitating conditions, the influence of the drones was positive (+), but the relation of AR was not investigated. The perceived risk was tested for the negative (-) influence of use intention of AR, but no significant relationship was found out for the drones. Among the significant influencing factors, hedonic motivation was the most powerful factor in AR and drones. Theoretical and practical implications are presented based on these results.

  • The purpose of this study is to figure out how the recognition for Jeonju hanok village would influence the traditional cultural images and the level of satisfaction with traditional Korean cuisine restaurants. A survey for this study was done from June $1^{st}$ to June $16^{th}$, 2013 to those who had visited traditional Korean restaurants in the Korea traditional village, except Jeonju citizens. The result are as follows. First, there are three factors settled as the recognition factors for the Korea traditional village, which are food factors, Korean traditional beauty factors, and historicity factors. Also, there are two image factors settled, which are traditional image factors and cultural image factors. These factors are verified for the hypothesis. Second, for "The recognition for the Korea traditional village would influence the cultural image" from hypothesis 2, it is accepted as the food factors are found to have the greatest influence. Third, as a result of the hypothesis 3, "The recognition for traditional cultural image would influence the level of satisfaction with traditional Korean cuisine restaurants," it is accepted as the Korean traditional beauty factor has the greatest influence. For the future studies, various studies for restaurant satisfaction levels for each type of restaurant should be conducted and many efforts for maintaining good images for better satisfaction with traditional Korean restaurants are highly required.

  • A contingency model of outsourcing is developed from the information systems (IS) literature and strategic management literature in order to assess the following question: What factors influence change in the extent to which an organization outsources IS functions? Based on the literature, this study identifies four IS factors-gaps in information quality, IS support quality, IS staff quality, and IS cost effectiveness-and three organizational factors-the gap in financial performance, strategic orientation, and the role of information technology in an organization-that influence the change in degree of outsourcing. These factors are hypothesized to influence the change in the extent of an organization's outsourcing of IS functions. From a mail survey of 188 top IS executives in U.S. companies, the results of analysis of covariance and bivariate correlational and multivariate regression analyses provide the following major findings: (a) This study found support for the proposed research model. (b) The change in the degree of IS outsourcing is determined by gaps in information quality, IS support quality, IS cost effectiveness, and financial performance and by the role of IT among IS and organizational factors.
